FIG. 1 is a perspective view of a first embodiment of the cartridge of the present invention. FIG. 2 is a longitudinal sectional view of the cartridge shown in FIG. FIG. 3 is a view for explaining the function of the first valve of the cartridge shown in FIG. FIG. 4 is a view for showing a modification of the cartridge shown in FIG. FIG. 5 is a view for showing another modification of the cartridge shown in FIG. FIG. 6 is a view for showing another modification of the cartridge shown in FIG.

In the following description, the left rear side of FIG. 1 and the left side of FIGS. 2, 4, 5, and 6 are referred to as “base ends”, and the right front side of FIG. The right side of FIG. 2, FIG. 4, FIG. 5 and FIG.

The cartridge 1 shown in FIG. 1 has a gas inlet for allowing gas to flow in, a gas outlet for ejecting gas, a storage portion 2 for storing an arbitrary substance 5, and a gas in the storage portion 2 A first valve (check valve) 3 connected to the inflow port and a second valve (check valve) 4 connected to the gas outlet of the storage unit 2 are provided. In addition, the gas that flows into the storage unit 2 through the gas inlet and is ejected from the storage unit 2 to the outside through the gas outlet is not particularly limited. For example, air (outside air), carbon dioxide gas, Active gas, noble gas, etc. are mentioned.

The storage unit 2 has a long cylindrical shape, and stores an arbitrary substance 5 therein. A gas inflow port for allowing gas to flow in is formed on the base end side of the storage unit 2, and a gas injection port for discharging gas is formed on the front end side of the storage unit 2. Therefore, the gas that has flowed into the storage unit 2 through the gas inflow port passes through the storage unit 2 and then jets out of the storage unit 2 through the gas outlet.

The constituent material of the storage unit 2 is not particularly limited, but a metal, a thermoplastic resin, a thermosetting resin, an EVOH (ethylene / vinyl alcohol copolymer) resin, and a laminate resin that is a processing resin obtained by laminating a plurality of materials. A material having a high gas barrier property such as glass is preferable. The characteristics of the constituent materials of the storage section 2 are shown in Table 1 below.

The substance adsorption property referred to here is a performance indicating whether or not the substance 5 stored in the storage unit 2 is easily adsorbed to the constituent material of the storage unit 2. “Excellent” indicates that the substance 5 is difficult to be adsorbed by the constituent material of the storage unit 2, and “Low” indicates that the substance 5 is easily adsorbed by the constituent material of the storage unit 2.

If it is sufficient to manufacture a small amount of the cartridge 1 at the time of trial manufacture of the cartridge 1, it is preferable to configure the storage portion 2 using a metal with high workability. In the case where a metal is used as the constituent material of the storage unit 2, the storage unit 2 can be formed by cutting, casting, or processing aluminum, stainless steel, brass, or the like.

The storage unit 2 is preferably configured using a laminate resin or the like. Among the resins, it is preferable to configure the storage portion 2 using an EVOH resin having the highest level of gas barrier properties among thermoplastic resins. When a resin is used as the constituent material of the storage unit 2, the storage unit 2 can be formed by processing the resin by cutting, injection molding, or the like, or a combination thereof.

Further, when the storage unit 2 that satisfies the desired performance cannot be obtained with one kind of material, the storage unit 2 is configured using a laminate resin that is a processing resin obtained by laminating a plurality of materials. It is preferable. For example, by forming the storage portion 2 using a laminate resin in which an aluminum film having a high gas barrier property is laminated on a polypropylene resin that is lightweight and has a high workability but a low gas barrier property, the lightweight and high workability and The accommodating part 2 provided with gas barrier property can be obtained.

When the shape of the storage part 2 is simple, these glass processing costs are low, so that the storage part 2 can be formed at low cost.

Further, after the storage part 2 is formed of the above-described material, a functional material may be overcoated on the surface (inner surface or outer surface) of the storage part 2. For example, fluorine processing or aluminum vapor deposition is performed on the surface of the storage unit 2. Thereby, the characteristic of a functional material can be provided to the surface of the storage part 2.

In addition, when the accommodating part 2 is comprised using the material (for example, a thermoplastic resin or a thermosetting resin) with low adsorption | suction property with respect to a substance (the substance 5 is easy to adsorb | suck), the cartridge 1 is used disposable. That is, in this case, the material 5 stored in the storage unit 2 is not replaced and the cartridge 1 is not reused. In the case where the cartridge 1 is used in a disposable manner, it is preferable to configure the storage unit 2 using a resin (for example, a thermoplastic resin or a thermosetting resin) that is excellent in cost.

On the other hand, when the storage unit 2 is configured using a material (for example, metal or glass) having high anti-substance adsorptivity, the cartridge 1 is reused. That is, in this case, after removing the substance 5 stored in the storage unit 2 and removing the substance 5 from the storage unit 2 and on the surface of the storage unit 2 by ultrasonic cleaning or high temperature cleaning, the same type or different types By re-accommodating the substance 5 in the accommodating portion 2, the cartridge 1 can be reused.

The mode of the substance 5 stored in the storage unit 2 is not particularly limited, and a solid substance, a powdery substance, a liquid substance, or the like can be stored in the storage unit 2. When the substance 5 is a powdery substance, it is preferable to store the substance 5 in the storage unit 2 in a state where the powdery substance is supported on a gel-like or solid carrier. Further, when the substance 5 is a liquid substance, the substance 5 is stored in the storage unit 2 in a state in which the substance 5 is supported on a carrier that can soak and hold a liquid such as sponge, cloth, or fiber bundle core. It is preferable to store it in a container.

In particular, when the substance 5 is a liquid substance, it is preferable to impregnate the substance 5 into a fiber bundle core obtained by bundling polyester fibers and store the fiber bundle core in the storage unit 2. A fiber bundle core obtained by bundling polyester fibers or the like can be impregnated with a larger amount of the substance 5 than a sponge or cloth. Therefore, the amount of the substance 5 accommodated in the accommodating part 2 can be increased by using such a fiber bundle core as a support for the substance 5.

Moreover, the kind of the substance 5 accommodated in the accommodating part 2 is not specifically limited, For example, the adsorbent for adsorb | sucking substances in gas, such as a volatile substance containing a volatile component, activated carbon, a medicine, nicotine, Arbitrary naturally derived substances such as liquor, any artificially obtained chemical substances, etc., and combinations of two or more thereof can be stored in the storage unit 2.

The volatile substance stored in the storage unit 2 includes an aromatic substance (fragrance) containing a volatile aromatic component. The aromatic substance stored in the storage unit 2 is not particularly limited as long as it contains a volatile aromatic component. For example, a solid aromatic substance such as coffee beans, tea leaves, herbs, flowers, fragrant trees, solid To store powdery aromatic substances such as spices obtained by powdering the aromatic substances in liquid, liquid aromatic substances such as perfumes and perfumed oils, artificially synthesized aromatic components, etc. in the storage unit 2 Can do. These aromatic components have various effects such as a relaxing effect, an awakening effect, an appetite increasing effect, a concentration enhancing effect, an analgesic effect, and a deodorizing effect, depending on the type.

Only the gas flow path for allowing the gas to pass through is opened, so that the reverse flow of the gas from the inside of the storage portion 2 to the outside via the first valve 3 is prevented. That is, the first valve 3 also has a function as a check valve that prevents the backflow of gas from the inside of the storage portion 2 to the outside.

As shown in FIG. 2, the first valve 3 has an umbrella shape, a valve body 31 made of an elastic material, and a concave shape that opens to the base end side, and supports the valve body 31. And a seat 32. The distal end side of the valve seat 32 is connected to the gas inlet of the storage unit 2.

The valve body 31 of the first valve 3 includes a long shaft portion 311, an enlarged diameter portion 312 provided in the middle of the shaft portion 311, and an umbrella portion 313 provided at the tip of the shaft portion 311.

On the other hand, in FIG. 3B, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ is equal to or greater than a predetermined value Th ₁ (the valve opening pressure of the first valve 3). The state of the first valve 3 in the case of

As shown in FIG. 3A, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ is less than a predetermined value Th ₁ (the valve opening pressure of the first valve 3). In this case, the umbrella portion 313 of the valve body 31 is in contact with the valve seat 32 on the storage portion 2 side, and the gas flow path 322 of the valve seat 32 is closed by the umbrella portion 313 of the valve body 31.

On the other hand, as shown in FIG. 3B, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ is a predetermined value Th ₁ (the valve opening pressure of the first valve 3). ) or more when umbrella part 313 by the upstream pressure P ₁ is pushed up to the elastic deformation or upper, valve head 313 is separated from the valve seat 32, the gas flow path 322 is opened. At this time, the gas flows into the storage unit 2. Thereafter, when the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ becomes less than a predetermined value Th ₁ (the valve opening pressure of the first valve 3), the umbrella portion 313 The gas flow path 322 is closed by contacting the seat 32 again.

Returning to FIG. 2, the second valve 4 is connected to the gas outlet of the storage unit 2, and an upstream pressure P ₁ that is a pressure applied from the gas inflow side to the second valve 4. The differential pressure (P ₁ -P ₂ ) from the downstream pressure P ₂ , which is the pressure applied from the gas outflow side to the second valve 4, is a predetermined value Th ₂ (opening of the second valve 4 When the pressure becomes equal to or higher than the valve pressure, the gas is allowed to pass.

That is, the second valve 4 has a differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ , which is the internal pressure of the storage portion 2, and the downstream pressure P ₂ , at a predetermined value Th ₂ (second valve The valve functions as a valve that causes gas to flow out from the storage unit 2 to the outside only when the pressure is equal to or higher than (open valve pressure of 4), and otherwise does not flow gas from the storage unit 2 to the outside.

The second valve 4, when the upstream side pressure P ₁ is a pressure of the container 2 than the downstream pressure P _{2, (valve} opening pressure of the second valve 4) a predetermined value Th 2 or greater Only the gas flow path for allowing the gas to pass through is opened, so that the backflow of the gas from the outside through the second valve 4 into the storage portion 2 is prevented. In other words, the second valve 4 also has a function as a check valve that prevents a backflow of gas from the outside into the storage unit 2.

As shown in FIG. 2, the second valve 4 has an umbrella shape, a valve body 41 made of an elastic material, and a valve seat that has a concave shape that opens to the distal end side and supports the valve body 41. 42. The base end side of the valve seat 42 is connected to the gas outlet of the storage unit 2. Therefore, the gas that has passed through the storage unit 2 is ejected outside the cartridge 1 (storage unit 2) via the second valve 4.

The valve body 41 of the second valve 4 includes a long shaft portion 411, an enlarged diameter portion 412 provided in the middle of the shaft portion 411, and an umbrella portion 413 provided at the tip of the shaft portion 411. Prepare. The valve seat 42 of the second valve 4 includes an insertion hole 421 into which the shaft portion 411 of the valve body 41 is inserted, and a plurality of gas flow paths 422 for allowing gas to flow out from the storage portion 2 to the outside. . The shaft portion 411 of the valve body 41 is inserted into the insertion hole 421 of the valve seat 42, and the umbrella portion 413 of the valve body 41 is on the tip opening side of the valve seat 42 (the side from which the gas in the gas flow path 422 flows out, It is located on the downstream side of the gas flow), and the enlarged diameter portion 412 is located on the storage portion 2 side (the side into which the gas flows in the gas flow path 422, the upstream side of the gas flow).

The 2nd valve 4 is comprised so that the operation | movement similar to the operation | movement of the 1st valve 3 demonstrated with reference to FIG. 3 may be performed. That is, when the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ is equal to or greater than a predetermined value Th ₂ (the valve opening pressure of the second valve 4), the umbrella portion 413 is The gas flow path 422 is opened away from the valve seat 42. On the other hand, when the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ is less than a predetermined value Th ₂ (the valve opening pressure of the second valve 4), the umbrella of the valve body 41 The portion 413 is in contact with the valve seat 42 on the tip opening side of the valve body 41, and the gas flow path 422 of the valve seat 42 is closed by the umbrella portion 413 of the valve body 41.

In addition, the connection method to the gas inflow port of the storage part 2 of the 1st valve 3 and the connection method to the gas jet port of the storage part 2 of the 2nd valve 4 are not specifically limited, Screw type connection, press-fit A connection method such as combined connection or adhesion can be used.

The elastic material constituting the valve body 31 of the first valve 3 and the valve body 41 of the second valve 4 is preferably a highly elastic material such as a resin material or rubber, and has a high elasticity. Furthermore, it is more preferable that the fluororesin has excellent gas resistance and solution resistance.

The storage portion 2 is sealed by the first valve 3 and the second valve 4 having such a configuration. Therefore, unnecessary inflow of gas into the storage unit 2 and unnecessary outflow of gas from the storage unit 2 to the outside can be prevented. Thereby, the unnecessary drying of the substance 5 accommodated in the accommodating part 2 can be prevented.

When such a cartridge 1 is used, the inflow of gas into the storage portion 2 can be controlled by adjusting the upstream pressure P ₁ with respect to the first valve 3. Similarly, by adjusting the downstream pressure P ₂ for the second valve 4, it is possible to control the outflow of gas to the outside from the inside of container 2.

Therefore, by increasing the upstream pressure P ₁ with respect to the first valve 3 of the cartridge 1 and / or decreasing the downstream pressure P ₂ with respect to the second valve 4 of the cartridge 1, the inflow of gas into the storage portion 2. And the outflow of the gas from the inside of the storage part 2 to the outside can be controlled.

More specifically, when the cartridge 1 is not used, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the first valve 3 is a predetermined value Th ₁ ( Therefore, the first valve 3 is closed. Therefore, gas does not flow into the storage unit 2. Similarly, when the cartridge 1 is not used, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the second valve 4 is a predetermined value Th ₂ (second Therefore, the second valve 4 is closed. Therefore, gas does not flow out from the storage unit 2 to the outside. As a result, the storage portion 2 is sealed by the first valve 3 and the second valve 4 when the cartridge 1 is not used.

On the other hand, in use of the cartridge 1, downstream pressure P ₂ for the upstream side pressure P ₁ second valve 4 increases and / or cartridge 1 for the first valve 3 of the cartridge 1 is reduced. First, a case where the upstream pressure P1 for the first valve 3 of the cartridge ₁ is increased when the cartridge 1 is used will be described.

When the cartridge 1 is used, gas is supplied to the first valve 3 of the cartridge 1, and the upstream pressure P ₁ with respect to the first valve 3 increases. Thereafter, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ with respect to the first valve 3 and the downstream pressure P ₂ that is the internal pressure of the storage portion 2 is a predetermined value Th ₁ (first valve 3 The first valve 3 is opened, and the gas flows into the storage portion 2 through the first valve 3.

When gas flows into the storage portion 2 through the first valve 3, the internal pressure of the storage portion 2 increases, and the upstream pressure P ₁ with respect to the second valve 4 increases. Thereafter, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ for the second valve 4 and the downstream pressure P ₂ for the second valve 4 is a predetermined value Th ₂ (of the second valve 4). When the pressure is equal to or higher than the valve opening pressure, the second valve 4 is opened, and the gas flows out from the storage portion 2 to the outside through the second valve 4.

Thereafter, when the supply of gas to the first valve 3 of the cartridge 1 is stopped, the upstream pressure P1 to the _first valve 3 decreases. Thereafter, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ with respect to the first valve 3 and the downstream pressure P ₂ that is the internal pressure of the storage portion 2 is a predetermined value Th ₁ (first valve 3 The first valve 3 is closed, and the inflow of gas into the storage portion 2 via the first valve 3 is stopped.

When the inflow of gas into the storage unit 2 via the first valve 3 stops, the internal pressure of the storage unit 2 decreases, and the upstream pressure P ₁ with respect to the second valve 4 decreases. Thereafter, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ for the second valve 4 and the downstream pressure P ₂ for the second valve 4 is a predetermined value Th ₂ (of the second valve 4). When the pressure is less than the valve opening pressure, the second valve 4 is closed, and the outflow of gas from the inside of the storage portion 2 via the second valve 4 to the outside stops.

Then, when using the cartridge 1, a case where the downstream pressure P ₂ is reduced to the second valve 4 of the cartridge 1. In this case, when the cartridge 1 is used, gas suction is performed on the second valve 4 of the cartridge 1, and the downstream pressure P ₂ with respect to the second valve 4 decreases. Thereafter, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ for the second valve 4 and the downstream pressure P ₂ for the second valve 4, which is the internal pressure of the storage portion 2, is a predetermined value Th _2. (Valve opening pressure of the second valve 4) When the pressure is equal to or higher than the above, the second valve 4 is opened, and the gas flows out from the storage portion 2 to the outside via the second valve 4.

When the gas flows out from the storage portion 2 to the outside via the second valve 4, the internal pressure of the storage portion 2 decreases and the downstream pressure P ₂ with respect to the first valve 3 decreases. Thereafter, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ with respect to the first valve 3 and the downstream pressure P ₂ that is the internal pressure of the storage portion 2 is a predetermined value Th ₁ (first valve 3 The first valve 3 is opened, and the gas flows into the storage portion 2 through the first valve 3.

Thereafter, when the suction of the gas to the second valve 4 of the cartridge 1 is stopped, the downstream pressure P2 to the _second valve 4 increases. Thereafter, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ for the second valve 4 and the downstream pressure P ₂ for the second valve 4, which is the internal pressure of the storage portion 2, is a predetermined value Th _2. When the pressure is less than (the valve opening pressure of the second valve 4), the second valve 4 is closed, and the outflow of gas from the inside of the storage unit 2 via the second valve 4 to the outside stops.

When outflow of gas to the outside from the inside of container 2 through the second valve 4 is stopped, it increases the internal pressure of the container 2 is, downstream pressure P ₂ to the first valve 3 is increased. Thereafter, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ with respect to the first valve 3 and the downstream pressure P ₂ that is the internal pressure of the storage portion 2 is a predetermined value Th ₁ (first valve 3 The first valve 3 is closed, and the inflow of gas into the storage portion 2 via the first valve 3 is stopped.

As described above, by supplying gas to the first valve 3 of the cartridge 1 and / or by performing suction of the gas to the second valve 4 of the cartridge 1, the storage unit It is possible to control the inflow of gas into 2 and the outflow of gas from inside the storage unit 2 to the outside.

In the cartridge 1 of the present invention, the internal pressure of the storage unit 2 increases due to the change (evaporation or the like) of the substance 5 stored in the storage unit 2, and the upstream of the second valve 4 that is the internal pressure of the storage unit 2. When the differential pressure (P ₁ -P ₂ ) between the side pressure P ₁ and the downstream pressure P ₂ with respect to the second valve 4 is equal to or greater than a predetermined value Th ₂ (the valve opening pressure of the second valve 4) In addition, the second valve 4 is opened, and gas flows from the inside of the storage portion 2 to the outside via the second valve 4. Therefore, the internal pressure of the storage unit 2 can be automatically reduced. For this reason, it is possible to prevent the internal pressure of the storage unit 2 from increasing due to a change (evaporation or the like) of the substance 5 stored in the storage unit 2, and the storage unit 2 can be prevented from being ruptured or damaged. Can increase the sex.

In the cartridge 1 of the present invention, even if the external pressure (such as atmospheric pressure) of the cartridge 1 is decreased or increased due to a change in atmospheric pressure or the like, the differential pressure between the external pressure of the cartridge 1 and the internal pressure of the storage portion 2 is increased. It is kept within a certain range. For example, if the external pressure of cartridge 1 is increased by a change in air pressure or the like, the upstream pressure P ₁ with respect to the first valve 3 is increased. Thereafter, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ with respect to the first valve 3 and the downstream pressure P ₂ that is the internal pressure of the storage portion 2 is a predetermined value Th ₁ (first valve 3 The first valve 3 is opened, and the gas flows into the storage portion 2 through the first valve 3. As a result, the internal pressure of the storage unit 2 increases, and the differential pressure between the external pressure of the cartridge 1 and the internal pressure of the storage unit 2 is maintained in a certain range.

On the other hand, if the external pressure of cartridge 1 is reduced by atmospheric pressure change and the like, the downstream pressure P ₂ for the second valve 4 is reduced. Thereafter, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the second valve 4 is equal to or greater than a predetermined value Th ₂ (the valve opening pressure of the second valve 4). Then, the second valve 4 is opened, and the gas flows out from the storage unit 2 to the outside through the second valve 4. As a result, the internal pressure of the storage unit 2 decreases, and the differential pressure between the external pressure of the cartridge 1 and the internal pressure of the storage unit 2 is maintained in a certain range.

Further, a cap for sealing the first valve 3 and the second valve 4 may be attached to the proximal end side opening of the first valve 3 and the distal end side opening of the second valve 4. Thereby, it is possible to prevent the first valve 3 and / or the second valve 4 from being opened when the external pressure of the cartridge 1 is changed due to a change in atmospheric pressure as described above.

In the present embodiment, since the first valve 3 and the second valve 4 have the same configuration, the valve opening pressure Th ₁ of the _first valve 3 and the valve opening of the second valve 4 are the same. The pressure Th ₂ is the same, but the present invention is not limited to this. For example, the valve opening pressure Th ₁ of the first valve 3 and the valve opening pressure Th ₂ of the second valve 4 may be different from each other.

For example, when a substance 5 having a high vapor pressure (a substance 5 that easily volatilizes) is stored in the storage unit 2, the valve opening pressure Th ₂ of the _second valve 4 is higher than the valve opening pressure Th ₁ of the first valve 3. Also, the cartridge 1 may be configured so as to be larger (Th ₂ > Th ₁ ). Thereby, even when the internal pressure of the storage unit 2 is increased due to the volatilization of the substance 5, the volatilized substance 5 flows out of the storage unit 2 unintentionally through the second valve 4 together with the gas. It is possible to prevent the volatilized substance 5 from leaking and the trial period of the cartridge 1 from being shortened.

Further, even when the liquid substance 5 is stored in the storage unit 2, the valve opening pressure Th ₂ of the _second valve 4 is made larger than the valve opening pressure Th ₁ of the first valve 3 (Th ₂ > Th ₁ ), the cartridge 1 may be configured. Thereby, the internal pressure of the accommodating part 2 can be kept high compared with atmospheric pressure. Thereby, the boiling point of the liquid substance 5 accommodated in the accommodating part 2 can be raised, and evaporation of the liquid substance 5 can be suppressed.

Further, the cartridge 1 may be configured such that the valve opening pressure Th ₁ of the first valve 3 is larger than the valve opening pressure Th ₂ of the second valve 4 (Th ₁ > Th2 ₁ ). As a result, the valve opening pressure Th ₂ of the _second valve 4 becomes lower than the valve opening pressure Th _{1 of} the first valve 3, so that the valve opening pressure Th ₁ of the first valve 3 and the first valve 3 The opening and closing of the second valve 4 can be controlled by controlling only the upstream pressure P1.

The first embodiment of the cartridge 1 of the present invention has been described above with reference to FIGS. 1 to 3, but the present invention is not limited to this. For example, the cartridge 1 can be used in the manner shown in FIGS.

That is, by using the cartridge 1a in such a manner, a plurality of mixed aroma components can be ejected to the outside of the cartridge 1a together with the gas. In this case, it is preferable to use air (outside air), carbon dioxide gas, or the like as the gas supplied into the storage unit 2 and ejected from the storage unit 2 to the outside.

The cartridge 1a having such a configuration is an adsorbing substance for the substance 5 accommodated in the accommodating portion 2 of the two cartridges 1 to adsorb a substance (for example, an impurity) in a gas such as activated carbon. Also useful in cases. By storing different types of adsorbing substances that adsorb different substances in the gas in the storage units 2 of the two cartridges 1, different substances in the gas can be adsorbed in the storage units 2. Thereby, the gas in a state where a plurality of substances are removed can be ejected to the outside of the cartridge 1a. In this case, it is preferable to use air (outside air) as the gas supplied into the storage unit 2 and ejected from the storage unit 2 to the outside. Thereby, the air of the place where the card ridge 1a was provided can be wash | cleaned.

Similarly to the cartridge 1a shown in FIG. 4, the number of cartridges 1 used in the cartridge 1b shown in FIG. 5 is not particularly limited, and any number of cartridges 1 equal to or greater than 2 can be used in the cartridge 1b. Further, the connection between the plurality of cartridges 1 is not limited to the direct connection between the second valve 4 of the proximal-side cartridge 1 and the storage portion 2 of the distal-side cartridge 1 as shown in FIG. A plurality of cartridges 1 may be connected by connecting the second valve 4 of the cartridge 1 on the proximal end side and the storage portion 2 of the cartridge 1 on the distal end side via an arbitrary connecting member such as a tube.

A cartridge 1c shown in FIG. 6 is obtained by omitting the storage portion 2 from the cartridge 1 shown in FIGS. FIG. 6A shows a perspective view of the cartridge 1c. FIG. 6B shows a longitudinal sectional view of the cartridge 1c.

As the elastic material constituting the valve body 31, the same elastic material as that constituting the valve bodies 31 and 41 used in the first valve 3 and the second valve 4 of the cartridge 1 of the first embodiment is used. be able to.

The valve seat 32 has a substantially cylindrical overall shape. The valve seat 32 includes a cylindrical proximal end opening 323 that opens downward in FIG. 7, a cylindrical connection portion 324 provided on the upper surface of the proximal end opening 323, and an upper surface of the connection portion 324. The circular gas flow path 322 formed so that the upper surface of the connection part 324 may be penetrated, and the ring-shaped flange part 325 formed in the upper surface edge part of the connection part 324 are provided.

The outer diameter of the base end side opening 323 is larger than the outer diameter of the connection portion 324. Further, the hollow portion of the base end side opening 323 and the hollow portion of the connection portion 324 communicate with each other. Therefore, the gas supplied from the base end side opening portion 323 side passes through the hollow portion of the base end side opening portion 323 and the hollow portion of the connection portion 324, and flows out of the valve seat 32 through the gas flow path 322. To do. Therefore, in the valve seat 32 of the present embodiment, the lower side (base end side opening 323 side) in FIG. 7 is the upstream side of the gas flow, and the upper side (connection part 324 side) in FIG. It is downstream of the flow. In addition, a ring-shaped protruding portion 326 that engages with the holding member 33 is formed on the outer peripheral surface of the connecting portion 324.

The flange portion 325 is formed so as to protrude upward at the upper edge of the connection portion 324, and defines a space for placing the membrane valve body 31 thereon. The membranous valve body 31 is placed on the upper surface of the connection portion 324 and in a space defined by the flange portion 325. That is, the membrane-like valve element 31 is placed on the side (downstream side) of the gas flow path 322 of the valve seat 32 from which gas flows out.

The holding member 33 has a function of holding the membranous valve body 31 on the upper surface of the connection portion 324 of the valve seat 32. By the holding member 33, the membrane-like valve element 31 is held on the gas outflow side (downstream side of the gas flow) of the gas flow path 322 of the valve seat 32.

The holding member 33 has a substantially cylindrical overall shape. The holding member 33 opens downward in FIG. 7, and has a cylindrical connection part 331 connected to the connection part 324 of the valve seat 32, and a cylindrical tip side opening part 332 provided on the upper surface of the connection part 331. And.

The outer diameter of the connection portion 331 of the holding member 33 is substantially equal to the outer diameter of the proximal end side opening 323 of the valve seat 32. Further, the hollow portion of the connection portion 331 of the holding member 33 has a shape corresponding to the connection portion 324 of the valve seat 32. Further, a ring-shaped protrusion 333 that engages with a ring-shaped protrusion 326 formed on the outer peripheral surface of the connection part 324 of the valve seat 32 is formed on the inner peripheral surface of the connection part 331 of the holding member 33. ing.

The hollow portion of the connection portion 331 and the hollow portion of the distal end side opening portion 332 communicate with each other via a ring-shaped insertion hole 334 formed in the lower surface of the distal end side opening portion 332. Therefore, the gas that has flowed into the holding member 33 via the gas flow path 322 of the valve seat 32 flows into the hollow portion of the distal end side opening 332 of the holding member 33 via the ring-shaped insertion hole 334, and then It flows out of the front end side opening 332.

Also, a pressing portion 335 formed so as to protrude downward from the lower surface of the distal end side opening 332 is formed on the lower surface of the distal end side opening 332. In the state where the first valve 3 shown in FIG. 7 is assembled, the pressing portion 335 contacts the substantially central portion of the upper surface of the membrane-like valve body 31, and the membrane-like valve body 31 is connected to the connection portion of the valve seat 32. Hold on top of 324.

With the membrane valve body 31 placed on the upper surface of the connection part 324 of the valve seat 32, the connection part 324 of the valve seat 32 is inserted into the hollow part of the connection part 331 of the holding member 33, By engaging a ring-shaped protrusion 326 formed on the outer peripheral surface of the connection portion 324 and a ring-shaped protrusion 333 formed on the inner peripheral surface of the connection portion 331 of the holding member 33, a membrane is obtained. The valve body 31 can be held between the valve seat 32 and the holding member 33.

The first valve 3 of the present embodiment having such a configuration has an upstream pressure P ₁ applied from the upstream side of the gas flow to the membrane valve body 31 and the membrane valve body 31. When the differential pressure (P ₁ -P ₂ ) from the downstream pressure P ₂ applied from the downstream side of the gas flow becomes equal to or higher than a predetermined value Th ₁ (the valve opening pressure of the first valve 3), It is comprised so that gas may pass. That is, the first valve 3 of the present embodiment provides the same function as the first valve 3 used in the cartridge 1 of the first embodiment.

Specifically, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the membrane-like valve body 31 is a predetermined value Th ₁ (the valve opening pressure of the first valve 3). ), The membranous valve body 31 closes the gas flow path 322 of the valve seat 32. Therefore, in this state, the first valve 3 does not pass gas.

On the other hand, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the membrane-shaped valve body 31 is equal to or greater than a predetermined value Th ₁ (the valve opening pressure of the first valve 3). in some cases, the portion not in contact with the pressed portion 335 of the film-like valve element 31 (film-shaped valve body 31 near portion), the elastic deformation or pushed towards the upper by the upstream pressure P _1, membranous A gap is formed between the valve body 31 and the upper surface of the connection portion 324 of the valve seat 32, and the gas flow path 322 of the valve seat 32 is opened. Therefore, in this state, the first valve 3 allows gas to pass.

Further, oil may be applied between the membrane-like valve body 31 and the upper surface of the connection portion 324 of the valve seat 32. Thereby, the adhesiveness with the upper surface of the connection part 324 of the membranous valve body 31 and the valve seat 32 can be improved.

The first valve 3 having such a configuration can also provide the same function as the first valve 3 used in the cartridge 1 of the first embodiment.

<< Third Embodiment >>
Next, a third embodiment of the cartridge of the present invention will be described with reference to FIG. FIG. 9 is a longitudinal sectional view of a valve used in the third embodiment of the cartridge of the present invention. In the following description, the upper side of FIG. 9 is referred to as “upper” or “upper”, and the lower side of FIG. 9 is referred to as “lower” or “lower”.

Hereinafter, the cartridge of the third embodiment will be described focusing on the differences from the cartridge of the second embodiment, and the description of the same matters will be omitted. In the cartridge 1 of the third embodiment, the configurations of the first valve 3 and the second valve 4 are different, and the other configuration is the same as the cartridge 1 of the second embodiment. Hereinafter, the first valve 3 and the second valve 4 used in the cartridge 1 of the third embodiment will be described.

Since the first valve 3 and the second valve 4 used in the cartridge 1 of the third embodiment have the same configuration, the configuration of the first valve 3 will be described below as a representative.

As shown in FIG. 9, the first valve 3 used in the cartridge 1 of the third embodiment is a valve having a spherical valve body 31 made of an elastic material and a gas flow path 322 for allowing gas to pass therethrough. A seat 32 and a holding member 33 for holding the spherical valve body 31 on the valve seat 32 are provided. In the present embodiment, a cylindrical pressing portion 335 is formed on the upper surface of the distal end side opening 332 of the holding member 33. In addition, a slit 336 is formed on the inner surface of the cylindrical pressing portion 335, and the gas that has passed through the gas flow path 322 of the valve seat 32 passes through the slit 336 and the opening 332 on the distal end side of the holding member 33. From the outside to the outside.

The valve body 31 according to the present embodiment is a spherical member made of an elastic material, and has a function of closing and opening the gas flow path 322 formed on the upper surface of the connection portion 324 of the valve seat 32. The elastic material constituting the valve body 31 includes the elastic material constituting the valve bodies 31 and 41 used in the first valve 3 and the second valve 4 of the cartridge 1 of the first embodiment and the second embodiment. Similar ones can be used.

As in the first valve 3 of the second embodiment, the spherical valve body 31 is held between the valve seat 32 and the holding member 33. In the state where the first valve 3 shown in FIG. 9 is assembled, the spherical valve body 31 is disposed so as to close the gas flow path 322 formed on the upper surface of the connection portion 324 of the valve seat 32.

The first valve 3 of the present embodiment having such a configuration includes an upstream pressure P _{1 applied} to the spherical valve body 31 from the upstream side of the gas flow, and a gas to the spherical valve body 31. When the differential pressure (P ₁ -P ₂ ) from the downstream pressure P ₂ applied from the downstream side of the flow of the gas becomes equal to or greater than a predetermined value Th ₁ (the valve opening pressure of the first valve 3), It is configured to pass through. That is, the first valve 3 of the present embodiment provides the same function as the first valve 3 used in the cartridge 1 of the first embodiment and the second embodiment.

Specifically, the upstream pressure P _{1 applied} to the spherical valve body 31 from the upstream side of the gas flow and the downstream pressure P _{1 applied} to the spherical valve body 31 from the downstream side of the gas flow. ₂ (P ₁ -P ₂ ) is less than a predetermined value Th ₁ (opening pressure of the first valve 3), the spherical valve body 31 causes the gas flow path 322 of the valve seat 32 to pass through the gas flow path 322. Block. Therefore, in this state, the first valve 3 does not pass gas.

On the other hand, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the spherical valve body 31 is equal to or greater than a predetermined value Th ₁ (the valve opening pressure of the first valve 3). If, spherical valve member 31 is elastically deformed by the upstream pressure P _1, a gap between the between the spherical valve body 31 and the valve seat 32, the gas passage 322 of the valve seat 32 is opened. Therefore, in this state, the first valve 3 allows gas to pass.

The spherical valve body 31 may be made of a hard material having a higher hardness than the constituent material of the holding member 33. In this case, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the spherical valve body 31 is equal to or greater than a predetermined value Th ₁ (the valve opening pressure of the first valve 3). In some cases, the spherical valve body 31 pushed upward by the upstream pressure P ₁ deforms the holding member 33. At this time, a gap is generated between the spherical valve body 31 and the valve seat 32, and the gas flow path 322 of the valve seat 32 is opened. Therefore, in this state, the first valve 3 allows gas to pass.

The first valve 3 having such a configuration can also provide the same function as that of the first valve 3 used in the cartridge 1 of the first embodiment and the second embodiment.

<< Fourth Embodiment >>
Next, a fourth embodiment of the cartridge of the present invention will be described with reference to FIGS. FIG. 10 is a longitudinal sectional view of a valve used in the fourth embodiment of the cartridge of the present invention. FIG. 11 is an exploded perspective view of the valve shown in FIG. In the following description, the upper side of FIGS. 10 and 11 is referred to as “upper” or “upper”, and the lower side of FIGS. 10 and 11 is referred to as “lower” or “lower”. In FIG. 11, in order to show the internal structure of the valve, the valve is shown with a part cut away.

Hereinafter, the cartridge according to the fourth embodiment will be described with a focus on differences from the cartridge according to the second embodiment, and description of similar matters will be omitted. In the cartridge 1 of the fourth embodiment, the configurations of the first valve 3 and the second valve 4 are different, and the other configuration is the same as the cartridge 1 of the second embodiment. Hereinafter, the first valve 3 and the second valve 4 used in the cartridge 1 of the fourth embodiment will be described.

Since the first valve 3 and the second valve 4 used in the cartridge 1 of the fourth embodiment have the same configuration, the configuration of the first valve 3 will be described below as a representative.

The holding member 33 of the present embodiment is a breathable membrane and is attached to the upper surface of the flange portion 325 of the valve seat 32. The constituent material of the holding member 33 of the present embodiment is not particularly limited as long as it has air permeability. For example, it is a laminated film PET / AL / ONY / CPP, a single layer film, a rubber elastic body such as nitrile rubber, or the like. The holding member 33 of this embodiment can be formed. The attachment of the holding member 33 to the upper surface of the flange portion 325 of the valve seat 32 is realized by a method such as adhesion.

The first valve 3 of the present embodiment having such a configuration has an upstream pressure P ₁ applied from the upstream side of the gas flow to the membrane valve body 31 and the membrane valve body 31. When the differential pressure (P ₁ -P ₂ ) from the downstream pressure P ₂ applied from the downstream side of the gas flow becomes equal to or higher than a predetermined value Th ₁ (the valve opening pressure of the first valve 3), It is comprised so that gas may pass. That is, the first valve 3 of the present embodiment provides the same function as the first valve 3 used in the cartridge 1 of the first to third embodiments.

Specifically, the upstream pressure P ₁ applied from the upstream side of the gas flow to the membrane-like valve body 31 and the downstream side applied from the downstream side of the gas flow to the membrane-like valve body 31. When the differential pressure (P ₁ -P ₂ ) from the pressure P ₂ is less than a predetermined value Th ₁ (the valve opening pressure of the first valve 3), the membrane-like valve element 31 is connected to the connection part of the valve seat 32. It contacts the upper surface of 324 and closes the gas flow path 322 of the valve seat 32. Therefore, in this state, the first valve 3 does not pass gas.

On the other hand, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the membrane-shaped valve body 31 is equal to or greater than a predetermined value Th ₁ (the valve opening pressure of the first valve 3). some cases, the film-like valve element 31 is lifted upward by the upstream pressure P _1, a gap between the film-like valve element 31 and the valve seat 32, the gas passage 322 of the valve seat 32 is opened . Therefore, in this state, the first valve 3 allows gas to pass.

In the present embodiment, the holding member 33 may be omitted. In this case, a part of the membrane-like valve body 31 is fixed to the upper surface of the connection portion 324 of the valve seat 32. In such a configuration, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the membranous valve body 31 is a predetermined value Th ₁ (opening of the first valve 3). When the pressure) or more, only the part which is not fixed to the upper surface of the connecting portion 324 of the valve seat 32 of the membrane-like valve body 31 is lifted upward by the upstream pressure P _1, film-like valve body 31 and the valve seat A gap is created between the two, and the gas flow path 322 of the valve seat 32 is opened. On the other hand, since a part of the membrane-like valve body 31 is fixed to the upper surface of the connection portion 324 of the valve seat 32, the membrane-like valve body 31 continues to be held on the upper surface of the connection portion 324 of the valve seat 32. In addition, fixation to the upper surface of the connection part 324 of the valve seat 32 of a part of membranous valve body 31 can be implement | achieved by arbitrary fixing methods, such as adhesion | attachment and a fitting type.

The first valve 3 having such a configuration can also provide the same function as that of the first valve 3 used in the cartridge 1 of the first to third embodiments.

In the cartridge 1 of the fifth embodiment, the configurations of the first valve 3 and the second valve 4 are different, and the other configuration is the same as the cartridge 1 of the first embodiment. Hereinafter, the first valve 3 and the second valve 4 used in the cartridge 1 of the fifth embodiment will be described.

Since the first valve 3 and the second valve 4 used in the cartridge 1 of the fifth embodiment have the same configuration, the configuration of the first valve 3 will be described below as a representative.

As shown in FIG. 12, the first valve 3 used in the cartridge 1 of the fifth embodiment has an umbrella-type valve body 31 made of an elastic material, and a gas flow path 322 for allowing gas to pass therethrough. A valve seat 32 and a holding member 33 for holding the umbrella-type valve body 31 are provided.

The valve body 31 of the present embodiment is an umbrella type member made of an elastic material, and has a function of closing and opening the gas flow path 338 formed in the holding member 33. As the elastic material constituting the valve body 31, the same elastic material as that constituting the valve bodies 31 and 41 used in the first valve 3 and the second valve 4 of the cartridge 1 of the first embodiment is used. be able to.

The valve body 31 of this embodiment is provided in the middle of the elongate shaft part 311 and the shaft part 311 similarly to the valve body 31 of the 1st valve 3 used in the cartridge 1 of 1st Embodiment. The enlarged diameter portion 312 and the umbrella portion 313 provided at the tip of the shaft portion 311 are provided. However, unlike the valve body 31 of the first valve 3 used in the cartridge 1 of the first embodiment, the umbrella part 313 of the valve body 31 of the present embodiment is formed by cutting the upper half of the sphere. It has a shape.

Similarly to the valve seat 32 of the first valve 3 used in the cartridge 1 of the first embodiment, the valve seat 32 of the present embodiment has an insertion hole 321 into which the shaft portion 311 of the valve body 31 is inserted, and gas. And a gas flow path 322 for supplying the inside of the storage unit 2.

The holding member 33 of the present embodiment has an overall shape of a substantially cylindrical shape, and from the inner peripheral part on the upper side of the hollow part on the tip side (the upper side in FIG. 12B), the center of the hollow part A ring-shaped protrusion 337 extending toward the surface is formed, and the gas flow path 338 is defined by the protrusion 337.

In the state where the first valve 3 shown in FIG. 12B is assembled, the lower surface of the hemispherical shape of the umbrella portion 313 of the valve body 31 is in contact with the protruding portion 337 of the holding member 33, and the holding member The 33 gas flow paths 338 are closed by the umbrella portion 313 of the valve body 31. Therefore, in this state, the first valve 3 does not pass gas.

On the other hand, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the hemispherical umbrella 313 is equal to or greater than a predetermined value Th ₁ (the valve opening pressure of the first valve 3). in some cases, the umbrella portion 313 of the hemispherical pushed elastically deformable or upper by the upstream pressure P _1, a gap between the hemispherical valve head 313 and the holding member 33, the gas flow path 338 of the holding member 33 Opened. Therefore, in this state, the first valve 3 allows gas to pass.

The first valve 3 having such a configuration can also provide the same function as that of the first valve 3 used in the cartridge 1 of the first to fourth embodiments.

<< Sixth Embodiment >>
Next, a sixth embodiment of the cartridge of the present invention will be described with reference to FIG. FIG. 13 is a view showing a valve used in the sixth embodiment of the cartridge of the present invention. FIG. 13A is a view showing a one-piece slit valve used in the sixth embodiment of the cartridge of the present invention. FIG. 13B is a view showing a two-piece type slit valve used in the sixth embodiment of the cartridge of the present invention.

Hereinafter, the cartridge according to the sixth embodiment will be described focusing on the differences from the cartridge according to the first embodiment, and description of similar matters will be omitted. In the cartridge 1 of the sixth embodiment, the configurations of the first valve 3 and the second valve 4 are different, and the other configurations are the same as the cartridge 1 of the first embodiment. Hereinafter, the first valve 3 and the second valve 4 used in the cartridge 1 of the sixth embodiment will be described.

Since the first valve 3 and the second valve 4 used in the cartridge 1 of the sixth embodiment have the same configuration, the configuration of the first valve 3 will be described below as a representative.

The 1st valve 3 used in cartridge 1 of this embodiment shown in Drawing 13 (a) is a 1 piece type slit valve. The first valve 3 can be formed by inserting a slit 34 in the center of a film (sheet) made of an elastic material. As an elastic material constituting the first valve 3, a rubber elastic body such as silicone, nitrile rubber, or fluororubber can be used.

Unlike the first valve 3 used in the cartridge 1 of the first to fifth embodiments, the first valve 3 having such a configuration prevents the backflow of gas from the inside of the storage unit 2 to the outside. Does not function as a check valve.

That is, the upstream pressure P ₁ applied from the upstream side of the gas flow to the first valve 3 of the present embodiment, and the downstream side applied from the downstream side of the gas flow to the membrane-like valve body 31. differential pressure between the pressure _{P 2 (P} 1 -P ₂₎ or _(P 2 _-P 1), i.e., the absolute value of the differential pressure is less than the predetermined value Th ₁ (the valve opening pressure of the first valve 3) In some cases, the slit 34 is closed. Therefore, in this state, the first valve 3 does not pass gas.

On the other hand, an upstream pressure P ₁ applied to the first valve 3 from the upstream side of the gas flow, and a downstream pressure P ₂ applied to the membrane-like valve body 31 from the downstream side of the gas flow. Differential pressure (P ₁ -P ₂ ) or (P ₂ -P ₁ ), that is, when the absolute value of the differential pressure is equal to or greater than a predetermined value Th ₁ (the valve opening pressure of the first valve 3) 34 is opened. Therefore, in this state, the first valve 3 allows gas to pass.

Thus, in the first valve 3 of the present embodiment, the slit 34 formed in the membrane valve body 31 opens and closes according to the pressure applied to the membrane valve body 31. Therefore, in the 1st valve 3 of this embodiment, the slit 34 functions as a gas flow path for allowing gas to pass through.

The first valve 3 used in the cartridge 1 of the present embodiment shown in FIG. 13B is a two-piece slit valve. The first valve 3 is configured by adhering a part (for example, both end portions) of end faces of two films (sheets) made of an elastic material to each other by heat fusion or the like. The portions of the end faces of the two films that are not bonded to each other form a slit 34. Such a two-piece slit valve can also provide the same function as the one-piece slit valve described above.

As described above, the cartridge 1 of the present invention has been described based on the illustrated embodiment. However, the present invention is not limited to this, and each configuration may be replaced with any one that can exhibit the same function. Or an arbitrary configuration can be added.

Those skilled in the art and in the art to which the present invention pertains will be able to make changes to the described configuration of the cartridge 1 of the present invention without significantly departing from the principles, concepts, and scope of the present invention, Odor squirting devices having a modified configuration are also within the scope of the present invention.

Moreover, in each embodiment, although the 1st valve 3 and the 2nd valve 4 have the same structure, this invention is not limited to this. For example, at least one of the first valve 3 and the second valve 4 has the same configuration as the first valve 3 and the second valve 4 of any of the first to sixth embodiments described above. The other of the first valve 3 and the second valve 4 may have the same configuration as that of the first valve 3 and the second valve 4 in a different embodiment.

Further, the first valve 3 and the second valve 4 used in the cartridge 1 of the present invention are not limited to the valves described in the first to sixth embodiments. For example, at least one of the first valve 3 and the second valve 4 may be replaced with an electromagnetic valve that opens and closes the valve by turning on and off electricity. In this case, the opening and closing of the first valve 3 and the second valve 4 is electrically controlled by a control device such as a CPU or a microcomputer connected to the first valve 3 and the second valve 4 of the cartridge 1. .

The cartridge 1 of the present invention has a cylindrical overall shape, but the present invention is not limited to this. For example, the cartridge 1 of the present invention may have an arbitrary cylindrical shape such as an elliptical cylindrical shape, a rectangular cylindrical shape, or a polygonal cylindrical shape.

FIG. 17 is a perspective view showing a blower mechanism and a cartridge of the ejection device shown in FIG. 18 is a block diagram schematically showing the ejection device shown in FIG.

In the following description, the upper side of FIGS. 14, 15, and 17 is referred to as “upper” or “upper”, and the lower side of FIGS. 14, 15, and 17 is referred to as “lower” or “lower”. To tell. Further, the left rear side of FIG. 14, FIG. 15, and FIG. 17, and the left side of FIG. 16 are referred to as “base end side”, and the right front side of FIG. 14, FIG. The right side is called the “tip side”. 15 and 16, the upper surface and both side surfaces of the housing of the ejection device are omitted in order to show the internal structure of the ejection device.

In the ejection device of the present invention, any of the cartridges 1 of the first to sixth embodiments described above can be used. However, the present embodiment assumes that the cartridge 1 of the first embodiment is used. The jet apparatus of a form is demonstrated. That is, the first valve 3 and the second valve 4 used in the cartridge 1 of the ejection device of the present embodiment are umbrella type check valves described with reference to FIGS.

The substance 5 stored in the storage unit 2 of the cartridge 1 is a volatile substance containing a volatile component, more specifically, a liquid fragrance substance containing a volatile fragrance component (for example, a liquid fragrance). The ejection device of this embodiment will be described as being carried on a fiber bundle core obtained by bundling polyester fibers and the like.

14 to 16 includes a housing 110 that accommodates each component of the ejection device 100, a first substrate 120a provided in the housing 110, and a substrate mounted on the first substrate 120a. The blower mechanism 130, the cartridge 1 connected to the blower mechanism 130 and containing a fragrance material, the second substrate 120b provided on the upper side of the blower mechanism 130, and the second substrate 120b, A control unit 140 for controlling the air blowing mechanism 130 and two batteries 150 mounted on the bottom surface of the housing 110 are provided. Moreover, the ejection device 100 may be configured to receive a signal from a sensor 170 (see FIG. 18) provided inside or outside the ejection device 100 via wired communication or wireless communication.

The housing 110 stores each component of the ejection device 100. The housing 110 has a long rectangular tube shape with a size of about 160 mm × 50 mm × 45 mm, for example. On the upper surface of the housing 110, an elliptical opening 111 is formed for projecting a power switch 141 for manually turning on / off the blower mechanism 130 out of the housing 110. In addition, a slit 112 for projecting an adjustment knob 142 for manually adjusting the amount of the aromatic component ejected from the ejection device 100 to the outside of the housing 110 is formed on the base end side surface of the housing 110. In addition, an opening 113 for projecting the gas ejection path 160 connected to the opening on the distal end side of the second valve 4 of the cartridge 1 to the outside of the housing 110 is formed on the distal end side surface of the housing 110. A plurality of columnar spacers 114 for holding the first substrate 120a and the second substrate 120b are provided on the bottom surface of the housing 110 on the base end side.

The constituent material of the housing 110 is not particularly limited, and examples thereof include a metal material, a ceramic material, a resin material, and a carbon material. Among these, from the viewpoint of easy processing of the housing 110 and improvement of the strength of the housing 110, it is preferable to configure the housing 110 using a metal material. Further, from the viewpoint of weight reduction and cost reduction of the housing 110, it is preferable to configure the housing 110 using a resin material.

The first substrate 120 a has a long flat plate shape, and is fixedly held at a base end side in the housing 110 by a plurality of spacers 114 while being separated from the bottom surface of the housing 110. The length of the first substrate 120 a in the longitudinal direction is shorter than the length of the housing 110 in the longitudinal direction. Therefore, when the first substrate 120 a is fixedly disposed on the proximal end side in the housing 110, a space for accommodating the two batteries 150 is formed on the distal end side in the housing 110.

The air blowing mechanism 130 is fixedly mounted on the first substrate 120 a and has a function of supplying gas into the cartridge 1. Examples of the air blowing mechanism 130 include a motor pump, a piezo pump, a fan, an air cleaner, an air conditioner, a fan heater, a knock pump, a mechanism that blows air by sucking or blowing gas (mainly air) at the mouth, and a manual pump. In the cartridge 1 by blowing a compressed gas such as a gas cylinder (for example, carbon dioxide gas, inert gas, rare gas, etc.) and generating an air flow Any other mechanism that can blow gas can be used. In the present embodiment, the blower mechanism 130 includes a blower part 131 and a connection part 132 that functions as an inflow path of gas supplied from the blower part 131 to the cartridge 1. In the present embodiment, the air blowing unit 131 includes a motor driven (controlled) by the control unit 140, a fan (rotor) that rotates by driving the motor, and a case that houses the motor and the fan. Supply air (atmosphere) to When the fan of the blower 131 is rotated in accordance with control from the control unit 140, gas is sent out into the connecting part 132. The gas (air) sent out into the connection part 132 flows into the cartridge 1 through the first valve 3 connected to the gas inlet of the storage part 2 of the cartridge 1.

The amount of gas supplied from the blower mechanism 130 into the cartridge 1 depends on the rotational speed of the fan. Therefore, the amount of gas supplied from the blower mechanism 130 into the cartridge 1 can be adjusted by controlling the rotational speed of the fan using the control unit 140. The supply amount of the gas supplied from the blower mechanism 130 into the cartridge 1 is at least, with respect to the cartridge 1, the valve opening pressure Th ₂ of the valve opening pressure Th ₁ and the second valve 4 of the first valve 3 of the cartridge 1 It is adjusted so that the above pressure can be applied.

In addition to satisfying these conditions, the amount of gas supplied from the blower mechanism 130 into the cartridge 1 is preferably about 0.001 L / min to 2.0 L / min, and 0.01 L More preferably, it is about / min to 1.0 L / min. If the gas supply amount is less than the lower limit value, it is not possible to secure a sufficient amount of the fragrance component ejected out of the cartridge 1, and the user may not be able to confirm the odor of the fragrance component depending on the type of the fragrance component. is there. On the other hand, when the gas supply amount exceeds the upper limit, the rotational speed of the fan of the air blowing unit 131 increases, and noise and vibration generated from the air blowing mechanism 130 may become significant.

As shown in FIGS. 15 to 17, the connection portion 132 of the air blowing mechanism 130 is connected to the proximal end side opening of the first valve 3 of the cartridge 1, and the distal end side opening of the second valve 4 of the cartridge 1. Is connected to a cylindrical gas ejection path 160.

When gas is supplied from the blower mechanism 130 to the first valve 3 of the cartridge 1, the upstream pressure P ₁ that is a gas pressure applied to the first valve 3 from the blower mechanism 130 side increases. Thereafter, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ with respect to the first valve 3 and the downstream pressure P ₂ that is the internal pressure of the storage portion 2 is a predetermined value Th ₁ (first valve 3 The first valve 3 is opened, and the gas flows into the storage portion 2 through the first valve 3.

When gas flows into the storage portion 2 through the first valve 3, the internal pressure of the storage portion 2 increases, and the upstream pressure P ₁ with respect to the second valve 4 increases. Thereafter, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ for the second valve 4 and the downstream pressure P ₂ for the second valve 4 is a predetermined value Th ₂ (of the second valve 4). When the pressure is equal to or higher than the valve opening pressure, the second valve 4 is opened, and the gas flows out from the storage portion 2 to the outside through the second valve 4.

When the gas passes through the storage unit 2 and flows out to the outside through the second valve 4, the volatile fragrance component drifting in the storage unit 2 is transported by the gas and stored together with the gas. It ejects from the gas outlet of part 2. Thereby, a volatile aroma component with gas can be ejected out of the cartridge 1.

The gas ejection path 160 has a cylindrical shape and functions as an ejection path for gas and aroma components that are ejected outside the ejection device 100 (cartridge 1). An opening (inlet) on the proximal end side of the gas ejection path 160 is connected to the opening on the distal end side of the second valve 4. The distal end portion of the gas ejection path 160 protrudes outside the housing 110 through the opening 113 of the housing 110, and the opening (ejection outlet) on the distal end side of the gas ejection path 160 opens to the outside of the ejection device 100. Yes. Therefore, the gas that has passed through the storage unit 2 is jetted out of the jetting device 100 (cartridge 1) through the second valve 4 and the gas jetting path 160 together with the aromatic component drifting in the storage unit 2.

As the constituent material of the gas ejection path 160, the same material as the constituent material of the storage unit 2 can be used. When the amount of gas supplied from the blower mechanism 130 into the cartridge 1 is within the above range, the diameter of the opening (jet port) of the gas ejection path 160 is about 0.1 mm to 10.0 mm. The thickness is preferably about 0.2 mm to 8.0 mm. If the diameter of the opening (jet port) of the gas ejection path 160 is less than the lower limit value, the gas supplied from the blower mechanism 130 may stagnate in the cartridge 1. On the other hand, when the diameter of the opening (ejection port) of the gas ejection path 160 exceeds the upper limit, the pressure of the gas ejected from the opening (ejection port) of the gas ejection path 160 is reduced, and the aroma component is moved far away. It may not be possible to erupt.

In the present embodiment, the cartridge 1 is attached with a recognition tag 6 (see FIG. 18) such as an RFID (Radio Frequency Identifier) tag that is read to identify the cartridge 1. The control unit 140 can identify the cartridge 1 by reading the recognition tag 6 of the cartridge 1.

Returning to FIGS. 15 and 16, the battery 150 is fixedly disposed on the front end side in the housing 110, and is connected to the control unit 140 via the power port 143 (see FIG. 18) of the control unit 140 to control the battery 150. Power is supplied to the unit 140. The battery 150 may be a rechargeable battery such as a lithium ion secondary battery, or may be a disposable battery such as a dry battery. In the example shown in FIGS. 14 to 16, the two batteries 150 have a long cylindrical shape and are arranged on the front end side in the housing 110 so as to sandwich the cartridge 1 in plan view. Yes.

The second substrate 120b is fixedly held above the air blowing mechanism 130 by a plurality of spacers 114. That is, in the present embodiment, the air blowing mechanism 130 is provided between the first substrate 120a and the second substrate 120b. Similar to the first substrate 120a, the second substrate 120b has a long flat plate shape. The length in the longitudinal direction of the second substrate 120b is shorter than the length in the longitudinal direction of the first substrate 120a, and the width (length in the short direction) of the second substrate 120b is the same as that of the first substrate 120a. It is almost equal to the width.

The control unit 140 is fixedly mounted on the second substrate 120b and has a function of controlling the blower mechanism 130. As shown in FIG. 18, the control unit 140 includes a power switch 141 for manually turning on / off the blower mechanism 130 and an adjustment knob for manually adjusting the ejection amount of the aromatic component ejected from the ejection device 100. 142, a power supply port 143 for inputting power to the control unit 140, a power supply unit 144 for supplying power to the motor of the blower mechanism 130, and an amount of power supplied to the motor of the blower mechanism 130 Variable resistor 145, a control unit 146 that controls the operation of the control unit 140, and a storage unit 147 that stores data, programs, modules, and the like for executing the operation of the control unit 140. .

In addition, the control unit 146 of the control unit 140 uses a data, a program, a module, or the like stored in the storage unit 147 to make a timer function, a count function for counting the number of rotations of the fan of the blower mechanism 130, a smartphone , Wireless communication functions such as BLE (Bluetooth (registered trademark) Low Energy), Zigbee, WiFi, etc. that execute wireless communication with external devices such as user terminals and external servers such as mobile phones and tablets, and the recognition tag 6 of the cartridge 1 A recognition tag identification function can be executed.

Further, the control unit 146 may be configured to receive a signal from one or more sensors 170 provided inside or outside the ejection device 100 via wired communication or wireless communication. In this case, the control unit 146 can control the ejection device 100 based on the signal received from the sensor 170. The sensor 170 that transmits a signal to the control unit 146 includes an odor sensor, a temperature sensor, a humidity sensor, a sound sensor, a light sensor, a thermal sensor, a human sensor, a pressure sensor, an acceleration sensor, a force sensor, and a current (or voltage). Any type of sensor, such as a sensor, a smoke sensor, an image sensor, a position sensor, or a combination thereof can be used.

The power supply unit 144 is connected to the motor of the blower mechanism 130, and the control unit 140 sends the power from the battery 150 via a regulator IC (Integrated Circuit) or DCDC converter IC of the power supply unit 144. The motor 130 can be supplied to drive the air blowing mechanism 130.

The power switch 141 is used for manually turning on / off the power supply from the power supply unit 144 of the control unit 140 to the motor of the blower mechanism 130. As shown in FIG. 14, the power switch 141 protrudes from the opening 111 of the housing 110 to the outside of the housing 110. Therefore, the user can manually turn on / off the power supply from the power supply unit 144 to the blower mechanism 130 by manually operating the power switch 141.

The adjustment knob 142 is used to manually adjust the resistance value of the variable resistor 145 of the control unit 140. By changing the resistance value of the variable resistor 145 using the adjustment knob 142, the value of the voltage output to the motor of the blower mechanism 130 via the regulator IC or DCDC converter IC of the power supply unit 144 is changed. Can do. The rotational speed of the fan of the blower mechanism 130 (rotational speed of the motor) depends on the voltage value output from the power supply unit 144 to the motor of the blower mechanism 130. Therefore, by changing the resistance value of the variable resistor 145 using the adjustment knob 142, the rotational speed of the fan of the blower mechanism 130, that is, the amount of gas supplied from the blower mechanism 130 into the storage unit 2 of the cartridge 1 is changed. It is possible to adjust and control the ejection amount of the aromatic component ejected out of the cartridge 1.

As shown in FIG. 14, the adjustment knob 142 protrudes from the slit 112 of the housing 110 to the outside of the housing 110. Therefore, the user manually operates the adjustment knob 142 to adjust the amount of gas supplied from the blower mechanism 130 into the storage unit 2 of the cartridge 1 and to control the amount of fragrance components ejected outside the cartridge 1. be able to.

The power supply port 143 is used to input electric power from the power supply such as the battery 150 to the control unit 140. The power supply port 143 is not particularly limited as long as power can be input from the power supply such as the battery 150 to the control unit 140, and examples thereof include a terminal for connecting a power supply line, a USB power supply port, and an ATA port.

Note that the power switch 141 and the adjustment knob 142 are used by the user to directly operate the control unit 140, but on / off of power supply from the power supply unit 144 to the motor of the blower mechanism 130 and out of the cartridge 1. The control unit 146 may change the ejection amount of the fragrance component to be ejected using data, a program, a module, or the like stored in the storage unit 147 or a signal received from one or more sensors 170. Good. Note that the control unit 146 changes the amount of the fragrance component ejected out of the cartridge 1 by the control unit 146 storing data, programs, modules, etc. stored in the storage unit 147 or one or more sensors 170. Is executed by changing a PWM (Pulse Width Modulation) signal output from the control unit 146 to the motor of the blower mechanism 130 based on the signal received from the control unit 146.

For example, the control unit 146 may drive the blower mechanism 130 at predetermined time intervals using the timer function to supply gas from the blower mechanism 130 into the storage unit 2. In addition, the control unit 146 identifies the cartridge 1 by identifying the recognition tag 6 of the cartridge 1 using the recognition tag identification function, and further, the fragrance substance (in the storage unit 2 of the cartridge 1 ( Depending on the type of the substance 5), the resistance value of the variable resistor 145 may be changed.

For example, when the fragrance substance stored in the storage unit 2 includes a fragrance component having a relatively strong odor, the control unit 146 reduces the ejection amount of the fragrance component ejected out of the cartridge 1. On the contrary, when the fragrance substance stored in the storage unit 2 includes a fragrance component having a relatively weak odor, the control unit 146 increases the ejection amount of the fragrance component ejected out of the cartridge 1.

Furthermore, the control unit 146 detects that the cartridge 1 has been replaced by using the recognition tag identification function, and further, the control unit 146 uses the above-described count function to detect the blower mechanism 130 from when the cartridge 1 has been replaced. The rotational speed of the fan may be counted, and the remaining amount of the fragrance component in the storage unit 2 may be determined based on the rotational speed of the fan of the air blowing mechanism 130. The determined remaining amount of the fragrance component in the storage unit 2 can be used to keep the amount of the fragrance component ejected out of the cartridge 1 constant.

Specifically, when the remaining amount of the fragrance component in the storage unit 2 is large, the density of the fragrance component floating in the storage unit 2 is high. Therefore, the control unit 146 reduces the amount of gas supplied from the blower mechanism 130 into the storage unit 2 of the cartridge 1. On the other hand, when the remaining amount of the fragrance component in the storage unit 2 is small, the density of the fragrance component floating in the storage unit 2 is low. Therefore, the control unit 146 increases the amount of gas supplied from the blower mechanism 130 into the storage unit 2 of the cartridge 1. By such control, the amount of the fragrance component ejected out of the cartridge 1 can be made constant regardless of the remaining amount of the fragrance component in the storage unit 2.

Further, when the controller 146 determines that the remaining amount of the fragrance component in the storage unit 2 has become a predetermined amount or less, the controller 146 uses the wireless communication function to connect the cartridge 1 to an external device such as a user terminal or an external server. You may notify that the replacement time is approaching. Further, the control unit 146 may transmit the remaining amount of the fragrance component in the storage unit 2 to an external device such as a user terminal or an external server at a predetermined time interval using a wireless communication function. Thereby, the user or the administrator of the odor ejection device 100 can accurately grasp the replacement time of the cartridge 1 and the remaining amount of the fragrance component in the storage unit 2.

In addition, the control unit 146 performs the ejection amount of the fragrance component in the storage unit 2 in the predetermined period (for example, several hours, one day, one week, one month), the remaining power of the battery 150, and the driving time of the blower mechanism 130. (I.e., the fragrance component ejection time in the storage unit 2), and various types of information relating to the ejection device 100 such as the type of the fragrance component in the storage unit 2 are transmitted to a user terminal or an external server using the wireless communication function. Also good. Thereby, the user or the administrator of the ejection device 100 can know the state of the ejection device 100 based on various types of information regarding the ejection device 100 accumulated in the user terminal or the external server. In addition, the user or administrator of the ejection device 100 can acquire information useful for the use and marketing of the ejection device 100 by analyzing various information related to the ejection device 100 accumulated in the user terminal or the external server. it can. For example, the user or the administrator of the ejection device 100 can analyze how often the cartridge 1 is replaced by analyzing various types of information related to the ejection device 100 accumulated in the user terminal or the external server. It is possible to acquire information such as whether or not the fragrance component is consumed most.

Further, the user terminal and the external server may receive various information related to the above-described ejection device 100 from the plurality of ejection devices 100 provided in various environments. Further, the control unit 146 of each ejection device 100 includes various information about the ejection device 100 as well as various information acquired from the sensor 170 (for example, the odor, temperature, humidity, sound, environment, etc. in which the ejection device 100 is provided). Light quantity, heat, pressure, position information, time stamp, etc.) may be transmitted to a user terminal or an external server using a wireless communication function. Thereby, in the user terminal or the external server, various types of information regarding the plurality of ejection devices 100 and various types of information acquired from the sensors 170 are linked and accumulated as big data. By analyzing such big data, the user or administrator of the ejection device 100 can obtain information useful for the use and marketing of the ejection device 100.

For example, the following usage modes are conceivable as usage modes of the ejection device 100 for acquiring information useful for the use and marketing of the ejection device 100 using such big data. In an exemplary mode of use, a plurality of ejection devices 100 that eject different types of fragrance components are installed in each store of the perfume maker, and each of the ejection devices 100 relates to a plurality of ejection devices 100 from the ejection device 100 to a user terminal or an external server. Various information and various information acquired from the sensor 170 are transmitted and stored as big data. By analyzing the big data accumulated in this way, it is possible to acquire various information useful for fragrance marketing.

For example, by analyzing the type of fragrance component in the storage unit 2 in association with the ejection amount of the fragrance component in the storage unit 2 in a predetermined period, information on which fragrance was most smelled by the customer (for example, , Popularity ranking of aromatic components). In addition, by analyzing the positional information of each store where the ejection device 100 is provided and the amount of fragrance components ejected in the storage unit 2 in a predetermined period, the scent preference for each store or region is analyzed. A tendency (difference) can be acquired. Further, by analyzing the temperature and humidity of the environment in which the ejection device 100 is provided and the ejection amount of the fragrance component in the storage unit 2 in a predetermined period, analysis is performed according to environmental conditions such as weather and temperature. Information about how customers' preferences for fragrances can be obtained.

Further, the control unit 146 may drive the air blowing mechanism 130 only when a specific type of cartridge 1 is attached to the ejection device 100 using the recognition tag identification function. For example, the control unit 146 stores the types of usable cartridges 1 specified in advance by the user in the storage unit 147, and stores the types of cartridges 1 identified by the control unit 146 and the storage unit 147. The blower mechanism 130 may be driven only when the type of the usable cartridge 1 matches. Thereby, it is possible to prevent the use of the ejection device 100 in a dangerous application in which a dangerous fragrance component (for example, a fragrance component having a tearing effect) is erroneously ejected.

Further, the control unit 146 turns on / off the supply of power from the power supply unit 144 to the motor of the blower mechanism 130 based on the signal received from the one or more sensors 170 and the fragrance component ejected outside the cartridge 1. You may perform the change of the ejection amount.

For example, when the sensor 170 is a human sensor, the presence of a person at a predetermined place can be detected by using the sensor 170. When the sensor 170 detects that a person is present at a predetermined location and transmits a signal to the control unit 146, the control unit 146 drives the ejection device 100. Accordingly, when the person is surely present, the ejection device 100 is automatically driven, and when the person is present, the amount of the aromatic component ejected out of the cartridge 1 is automatically increased (or reduced). Such control is possible.

For example, when the sensor 170 is an optical sensor, the brightness of the place (for example, a bedroom, an entrance, etc.) where the ejection apparatus 100 is attached can be detected by using the sensor 170. Based on the signal received from the sensor 170, the control unit 146 performs automatic on / off of driving of the ejection device 100 and / or automatic control of the ejection amount of the aromatic component ejected out of the cartridge 1. . When the ejection device 100 is attached to the bedroom, when the control unit 146 receives a signal indicating a sudden decrease in the brightness of the bedroom from the sensor 170, the control unit 146 determines that the light in the bedroom has been turned off. You may be comprised so that the aromatic component which has the effect of sleeping can be ejected. Further, when the controller 146 receives a signal from the sensor 170 indicating that the brightness of the bedroom is gradually increasing and exceeds a predetermined threshold value, the controller 146 determines that the night is dawning, and awakening effect. You may be comprised so that a certain aromatic component may be ejected. Moreover, the control part 146 may be comprised so that the ejection amount of the aromatic component which has a wake-up effect may be increased gradually according to the increase in the brightness of a bedroom.

In this manner, the control unit 146 is turned on / off of power supply from the power supply unit 144 to the motor of the blower mechanism 130 and ejected out of the cartridge 1 based on the signals received from the one or more sensors 170. By changing the ejection amount of the fragrance component, the drive of the ejection device 100 is automatically turned on / off according to various situations, and the ejection amount of the fragrance component ejected outside the cartridge 1 is automatically controlled. Control is possible.

In addition, the control unit 146 receives a control signal from an external device such as a user terminal or an external server using a wireless communication function, and from the power supply unit 144 to the motor of the blower mechanism 130 according to the received control signal. The on-off of the power supply and the change of the amount of the fragrance component ejected out of the cartridge 1 may be executed. Thereby, it becomes possible to remotely operate the ejection device 100.

As described above, in the cartridge 1 used in the ejection device 100 of the present invention, the storage unit 2 that stores the fragrance material (substance 5) includes the first valve 3 on the gas inlet side and the gas outlet side. It is sealed by the second valve 4. Therefore, in a state where no gas is supplied from the blower mechanism 130 into the cartridge 1 (a state where the ejection device 100 is not driven), the aromatic component in the storage unit 2 does not flow out of the ejection device 100.

Further, since the first valve 3 of the cartridge 1 is detachably connected to the connection portion 132 of the air blowing mechanism 130, the cartridge 1 can be easily removed. Therefore, the user using the ejection device 100 can easily change the fragrance component to be ejected by exchanging the cartridge 1.

Further, since the sealing structure of the cartridge 1 is composed of the first valve 3, the storage unit 2, and the second valve 4, and is very simple, the manufacturing cost of the cartridge 1 is low. Therefore, the cartridge 1 can be made disposable. Therefore, the user using the ejection device 100 can change the aroma component to be ejected at low cost by exchanging the cartridge 1.

When the bellows-like main body part 133 is pressed in a state where the outside air intake hole 134 of the air blowing mechanism 130 of the present embodiment is closed with a finger or the like, the bellows-like main body part 133 contracts in the longitudinal direction as shown in FIG. . As a result, the gas inside the bellows-shaped main body portion 133 is compressed, and the upstream pressure P ₁ with respect to the first valve 3 increases. Thereafter, the differential pressure (P ₁ −P ₂ ) between the upstream pressure P ₁ with respect to the first valve 3 and the downstream pressure P ₂ that is the internal pressure of the storage portion 2 is a predetermined value Th ₁ (first valve 3 The first valve 3 is opened, and the gas flows into the storage portion 2 through the first valve 3.

When gas flows into the storage portion 2 through the first valve 3, the internal pressure of the storage portion 2 increases, and the upstream pressure P ₁ with respect to the second valve 4 increases. Thereafter, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ for the second valve 4 and the downstream pressure P ₂ for the second valve 4 is a predetermined value Th ₂ (of the second valve 4). When the pressure is equal to or higher than the valve opening pressure, the second valve 4 is opened, and the gas flows out from the storage portion 2 to the outside through the second valve 4. At this time, the substance 5 (or a component derived from the substance 5) stored in the storage unit 2 flows out from the storage unit 2 to the outside together with the gas.

Thereafter, when the blocking of the outside air intake hole 134 of the air blowing mechanism 130 is released, the outside air intake hole 134 is opened, the outside air flows into the bellows-like main body part 133, and the bellows-like main body part 133 returns to the original state.

When the ejection device 400 is used as a suction device, the user holds the opening on the distal end side of the second valve 4 of the cartridge 1 of the ejection device 400 with his / her mouth and further uses the finger to the outside air intake hole 134 of the blower mechanism 130. In a closed state, the bellows-like main body part 133 is pressed to contract. By such an operation, the user derives from the substance 5 (or the substance 5) stored in the storage unit 2 together with the gas (air) ejected from the distal end side opening of the second valve 4 of the cartridge 1. Component) can be aspirated.

Further, the user sucks the substance 5 stored in the storage unit 2 by holding the opening at the front end of the second valve 4 of the cartridge 1 of the ejection device 400 and sucking gas (air). can do. In this case, the downstream pressure P ₂ for the second valve 4 is reduced. As a result, the substance 5 (or a component derived from the substance 5) is ejected together with the gas (air) in the storage unit 2 through the second valve 4 of the cartridge 1, and the user sucks the substance 5. Can do.

Thus, when the ejection device 400 is used as a suction device, powder medicine, suction medicine containing volatile medicinal ingredients, aroma, nicotine, and the like are used as the substance 5 stored in the storage section 2. When a medicine such as a powder medicine or an inhalation medicine containing a volatile medicinal component is used as the substance 5, by using the ejection device 400 of the present embodiment, the active ingredient of the medicine is directly applied to a user's trachea or lung by suction. Can be delivered.

When aroma or nicotine is used as the substance 5, the ejection device 400 of this embodiment can be used as a suction device such as an electronic cigarette. In particular, when nicotine is used as the substance 5, the ejection device 400 of the present embodiment can be used as a suction device for smoking cessation treatment. Since it is well known that the main cause of tobacco poisoning is nicotine, the ejection device 400 of this embodiment can be used for smoking cessation treatment by letting the user suck only nicotine.

Moreover, in the ejection apparatus 400 of this embodiment, the ventilation mechanism 130 is abbreviate | omitted, and also the slit type valve as used in 6th Embodiment of the cartridge 1 is used as the 1st valve 3 and the 2nd valve. It may be used. Since the slit type valve does not have a function as a check valve, the user can open either the proximal end opening of the first valve 3 or the distal end opening of the second valve 4 of the cartridge 1 by mouth. In addition, by sucking gas (air), the substance 5 (or a component derived from the substance 5) can be sucked.

As mentioned above, although the ejection apparatus of this invention was demonstrated based on embodiment of illustration, this invention is not limited to this, Each structure is substituted with the arbitrary things which can exhibit the same function. Or an arbitrary configuration can be added.

Similar to the mechanism 130, any mechanism such as a motor pump, a piezo pump, a fan, an air conditioner, a fan heater, a knock pump, or a manual pump can be used as the blower mechanism 520.

The gas inlet of the blower mechanism 520 is open to the internal space of the sealed container 510, and the gas discharge port of the blower mechanism 520 is connected to the sealed container 510 (substance collector) via the front end side opening of the sealed container 510. 500). When the air blowing mechanism 520 is driven, the gas in the sealed container 510 is discharged out of the sealed container 510, and the internal pressure of the sealed container 510 is reduced. When the internal pressure of the sealed container 510 is lowered, the downstream pressure P ₂ for the second valve 4 of the cartridge 1 is reduced. Thereafter, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ and the downstream pressure P ₂ with respect to the second valve 4 of the cartridge 1 is a predetermined value Th ₂ (the valve opening pressure of the second valve 4). If it becomes above, the 2nd valve 4 will open and gas will flow out in the airtight container 510 from the inside of the accommodating part 2 via the 2nd valve 4.

When the internal pressure of the container 2 is lowered by the outflow of gas into the sealed container 510 from the inside of container 2, the downstream pressure P ₂ to the first valve 3 of the cartridge 1 is reduced. Thereafter, the differential pressure (P ₁ -P ₂ ) between the upstream pressure P ₁ (atmospheric pressure or the like) and the downstream pressure P ₂ with respect to the first valve 3 of the cartridge 1 is a predetermined value Th ₁ (first valve 3 The first valve 3 opens and the gas flows from the outside of the substance collection device 500 into the storage unit 2 through the first valve 3. At this time, the floating substance floating in the outside air of the substance collection device 500 flows into the storage unit 2 together with the gas outside the substance collection device 500. As a result, the suspended substance flowing into the storage unit 2 is adsorbed by the adsorbed material stored in the storage unit 2.

Thereafter, when the driving of the blower mechanism 520 is stopped, the discharge of gas from the sealed container 510 (decompression in the sealed container 510) is stopped. Thereafter, in a state where the discharge of gas from the sealed container 510 (decompression in the sealed container 510) is stopped, the inflow of gas from the storage unit 2 through the second valve 4 into the sealed container 510 continues. The differential pressure (P ₁ −P ₂ ) between the downstream pressure P ₂ for the second valve 4 of the cartridge 1 and the upstream pressure P ₁ for the second valve 4 decreases. As a result, when the differential pressure (P ₁ -P ₂ ) is less than a predetermined value Th ₂ (opening pressure of the second valve 4), the second valve 4 is closed. Thereafter, with the second valve 4 closed, gas flows into the storage portion 2, and the downstream pressure P ₂ for the first valve 3 of the cartridge 1 and the upstream of the cartridge 1 for the first valve 3. The differential pressure (P ₁ -P ₂ ) with respect to the side pressure P ₁ decreases. As a result, when the differential pressure (P ₁ -P ₂ ) becomes less than a predetermined value Th ₁ (opening pressure of the first valve 3), the first valve 3 is closed.

As described above, by using the substance collection device 500 of the present invention, the suspended substance suspended in the gas outside the substance collection device 500 can be adsorbed to the adsorbed substance in the storage unit 2. Further, the floating substance can be collected by collecting the adsorbed substance in the storage unit 2 after using the substance collecting apparatus 500 (after driving the air blowing mechanism 520). Thereby, for example, it becomes possible to analyze a suspended substance suspended in a gas at an arbitrary place.

Moreover, in the substance collection apparatus 500 of this invention, the airtight container 510 is connected to the front end side opening of the 2nd valve 4 of the cartridge 1, Furthermore, the ventilation mechanism 520 is provided in the airtight container 510 inside. . Therefore, since the outside air can be directly sucked into the storage unit 2 of the cartridge 1 without going through the air blowing mechanism 520, extra impurities (for example, inside the air blowing mechanism 520) emitted from the air blowing mechanism 520 (for example, a pump or a fan). Dust, dust, and wear pieces generated by driving the air blowing mechanism 520 do not flow into the storage unit 2. Therefore, it is possible to prevent such impurities from adsorbing to the adsorbing substance in the storage unit 2. Thereby, only the suspended substance in the target gas can be adsorbed by the adsorbing substance in the storage unit 2 and collected.

As mentioned above, although the substance collection apparatus of this invention was demonstrated based on embodiment of illustration, this invention is not limited to this, Each structure is substituted with the arbitrary things which can exhibit the same function. Or an arbitrary configuration can be added.

Those skilled in the art and in the field to which the present invention pertains can make changes to the configuration of the described material collection device of the present invention without significantly departing from the principles, concepts, and scope of the present invention. A material collection device having a brazed and modified configuration is also within the scope of the present invention. For example, it is possible to change the shape of the sealed container of the substance collection device, or to arbitrarily change the configuration of the air blowing mechanism of the substance collection device.

According to the present invention, the storage unit has a gas inlet and a gas outlet and stores an arbitrary substance such as a volatile substance, the first valve connected to the gas inlet, and the gas outlet. And a second valve can be provided. Since the storage part for storing an arbitrary substance is sealed by the first valve on the gas inlet side and the second valve on the gas outlet side, the arbitrary substance (or the substance stored in the storage part (or It is possible to prevent a component derived from an arbitrary substance) from being ejected to the outside. Furthermore, since the cartridge has a simple sealing structure including the first valve, the storage portion, and the second valve, the cost is low. Therefore, the present invention has industrial applicability.
