Description

heating equipment

The present invention relates to a heating device, and more particularly to a heating device suitable for heating cigarettes at low temperatures.

The non-burn cigarette-type electronic cigarette smoking device is mainly divided into: an electronic atomizing suction device (commonly known as electronic cigarette), a non-combustion type cigarette smoking device, and a combination of an electronic atomizer and a non-combustion type. Three categories, such as a suction device.

The electronic cigarette system uses an essential oil filled with nicotine and spices to form a water droplet that can float in the air through an electron atomizer, and is heated by a heater, so that the smoker can absorb the mist beads containing nicotine and flavor. Similar to the purpose of smoking cigarettes. However, since the user is consuming artificial flavors, the user cannot taste the natural flavor from the tobacco leaves, and the flavor contents are often not labeled as health-harming ingredients.

The non-combustion type of smoke source of the non-combustion type can be divided into two types: the first type is a container or carrier containing a heat generating aerosol precursor, and the second type is a commercially available paper smoke as a smoke source.

Furthermore, the heating method of the non-combustion type suction device can also be divided into two types: the first heating method is a heater made of a PTC (Positive Temperature Coefficient) semiconductor heating element, or a nickel-chromium electric battery. The hot wire is wound into an elongated heater, which is heated by the center of the aerosol precursor container or the center of the commercially available cigarette, and the direction of thermal energy is diffused to the surface of the aerosol precursor container centered on the heater or heated. The device is centered by the commercially available cigarette center to the outside of the paper tube wall; the second heating method is heated by a heating tube type, and the container for heating the aerosol precursor or the commercially available cigarette can be placed in the heating tube. The direction of thermal energy transfer is diffused outside the container from which the aerosol precursor can be heated or from the outside of a commercially available cigarette paper tube.

However, the container which is conventionally heated to generate an aerosol precursor has a bulk design which is required to be miniaturized for its use, and thus the battery capacity used is limited, resulting in the following disadvantages:

First, you need to buy a special aerosol.

Second, because the volume of the container is small, not only the flavor is too light, but also the power capacity is limited, and continuous feeding or short smoking time is not possible.

Third, the aerosol-forming precursor is mainly composed of tobacco leaf extract and various additives such as a curing agent and an additive which is easy to be thermally evaporated, so that the flavor is completely different from that of the conventional tobacco leaf.

Furthermore, the conventional tubular heater places a general cigarette therein, but since the heating tube is heated from the outside of the cigarette, and the inside of the heating tube does not contact the outer surface of the cigarette to smoothly pick up and place the cigarette, it is necessary to increase the heating. The temperature of the tube (even increased to above 350 degrees Celsius) causes the high temperature to increase the concentration of tar and other hazardous substances produced after heating the cigarette, thereby increasing the risk of health hazards. Moreover, the outer paper tube of the cigarette is heated by an excessively high temperature, causing the paper tube to emit an odor that is heated by an excessively high temperature, which adversely affects the flavor.

Moreover, since the conventional PTC heater (such as the CN103859608A patent) is inflexible and flat, and the heating sheet is thick and wide, it is only used for special smoking articles, and the smoking article is not too long to heat the PTC. The piece is inserted into the cigarette. If a commercially available cigarette is used, the PTC heating sheet cannot be smoothly inserted into the cigarette, and the paper tube of the cigarette exterior is damaged.

In addition, the combination of the atomizer and the non-combustion type cigarette smoker, such as the JP 2017-127300 A patent, improves the flavor of the smoke when sucking, but also increases the risk of health hazards (such as excessive nicotine intake). ), and this style is likely to cause an increase in power consumption, thereby reducing the number of times a single charge can be used.

Therefore, how to overcome various problems of the prior art is an important issue.

In order to solve the above problems in the prior art, the present invention discloses a heating device, comprising: a carrier having an accommodation space and an opening connecting the accommodation space; and an electric heating tube disposed in the accommodation space; And the electric heating tube has two electrode portions and an opening end facing the opening.

In the aforementioned heating device, the carrier is a sleeve. For example, the electric heating tube is disposed coaxially with the carrier.

In the above heating device, the electric heating tube has a tapered annular cylindrical shape, and has two slits on the wall surface thereof to define the two electrode portions. For example, the electric heating tube is formed by removing a part of the sheet from a piece of body and crimping, and integrally forming the two electrode portions and the opening end.

In the aforementioned heating device, the open end is a tip end.

In the foregoing heating device, a base for assembling the carrier is further included. For example, the base has a recess for receiving the carrier, and a bottom is disposed on the bottom of the recess to fix the carrier and the electric heating tube. Alternatively, there is a space between the carrier and the base.

In the foregoing heating device, an electronic control unit electrically connected to the electric heating tube is further included to transmit current to the two electrode portions to heat the electric heating tube.

In the foregoing heating device, a sensor for determining the position of the carrier, such as an acceleration detector or a face proximity detector, is included.

It can be seen from the above that the heating device of the present invention mainly uses the design of the carrier and the electric heating tube to directly and uniformly heat the tobacco without using a special cigarette or a special aerosol precursor carrier container, etc. Knowing the technology, the heating device of the present invention can heat the tobacco in a low temperature manner, thereby achieving the best effect of smoking cigarettes in a non-combustion manner.

The embodiments of the present invention are described below by way of specific embodiments, and those skilled in the art can readily appreciate other advantages and functions of the present invention from the disclosure of the present disclosure.

It is to be understood that the structure, the proportions, the size and the like of the drawings are only used in conjunction with the disclosure of the specification for the understanding and reading of those skilled in the art, and are not intended to limit the implementation of the present invention. The conditions are limited, so it is not technically meaningful. Any modification of the structure, change of the proportional relationship or adjustment of the size should remain in this book without affecting the effectiveness and the purpose of the creation. The technical content revealed by the creation can be covered. In the meantime, the terms "upper" and "one" as used in this specification are for convenience of description only, and are not intended to limit the scope of implementation of the creation, and the relative relationship is changed or adjusted. Under the technical content of substantive changes, it is also considered to be the scope of implementation of this creation.

Fig. 1 is a perspective view showing the side of the heating device 1 of the present invention. As shown in FIG. 1, the heating device 1 is a non-combustion type cigarette smoking device, comprising: a carrier member 10, an electric heating tube 11, a base 12 and an electronic control unit 13.

The carrier 10 has an accommodating space S and an opening 10a that communicates with the accommodating space S.

In this embodiment, the carrier 10 is a sleeve which can be made of a metal, alloy or ceramic material and has a cylindrical shape (eg, 2A). The figure shows) or a rectangular strip (as shown in Fig. 2B), but is not limited to the above.

Moreover, the accommodating space S is a cylindrical passage to facilitate the accommodation of cigarettes of a general specification. For example, the accommodating space S is connected to both ends of the carrier 10 such that the opening 10a is formed at one end and the interface 10b is formed at the other end.

The electric heating tube 11 is coaxially disposed in the accommodating space S, and the electric heating tube 11 includes two electrode portions 111, 112, and a contact end 11b toward the bottom of the accommodating space S (or toward the interface 10b) ( It is a contact point of the electrode portions 111, 112, and an opening end 11a facing the opening 10a, wherein the contact end 11b can protrude from the interface 10b as needed.

In the present embodiment, as shown in FIGS. 3A and 3B, the electric heating tube 11 has a tapered (unclosed) column shape, and two corresponding slits 110a, 110b are formed on the front and rear wall surfaces, respectively. The two electrode portions 111 and 112 are defined such that the two electrode portions 111 and 112 are the circumferential surfaces of the electric heating tube 11. For example, the two slits 110a, 110b extend from top to bottom, wherein the slit 110a communicates with the opening end 11a, and the slit 110b is not connected to the opening end 11a, so that the opening end 11a can connect the two electrodes. The portion 111, 112, and the slit 110b of the wall surface of the electric heating tube 11 is farther from the opening end 11a than the slit 110a of the wall surface of the electric heating tube 11. Thereby, the current for heating can flow through the electric heating tubes 11 by the two electrode portions 111, 112 to heat the electric heating tubes 11.

Furthermore, the electric heating tube 11 is a high-resistance electric heating conductor, and the material thereof may be an alloy (but not a semiconductor material), for example, a nickel-chromium alloy (Ni-Cr Alloy) or an iron-chromium-aluminum alloy system (Fe- Cr-Al Alloy), or stainless Steel alloys (Stainless Steel Alloy), etc., may also be added with other trace metals to facilitate corrosion protection or processing. The structure and material of the electric heating pipe 11 are not limited to the above.

Moreover, the opening end 11a is a tip end of the top, such as an arrow shape, and has a slanted hole A at the front thereof, and the oblique shape of the slant hole A can be curved (as shown in FIGS. 4A, 4B and 4C). Geometric shapes with right angles (as shown in Figures 4D and 4E) or geometric shapes with curved corners (as shown in Figures 4F and 4G). The configuration regarding the opening end 11a is not limited to the above.

In addition, the electric heating tube 11 can remove a part of the sheet from a piece of body and curl, and integrally form the two electrode portions 111, 112 and the opening end 11a.

The base 12 is assembled with the carrier 10, for example, the base 12 has a recess 120 for receiving the carrier 10.

Specifically, as shown in FIG. 1 , a fixing seat 14 can be disposed at the bottom of the recess 120 to fix the interface 10 b of the carrier 10 and the contact end 11 b of the heating tube 11 . In this embodiment, the material forming the fixing base 14 is insulated and/or high temperature resistant (can withstand a material greater than 100 ° C, preferably a material that can withstand more than 230 ° C), and the shape of the recess 120 is The carrier 10 is shaped like a circular through hole so that the carrier 10 is fixed to the bottom of the recess 120 with its side of the interface 10b.

Furthermore, the carrier 10 is coaxially disposed in the recess 120, so that the recess 120 and the accommodating space S define a double-sleeve structure.

The electronic control unit 13 is electrically connected to the electric heating tube 11. For example, the electronic control unit 13 includes a controller 130 having a control switch 130a and a power source 131 for supplying power to the controller 130.

In the embodiment, the electronic control unit 13 is embedded in the base 12, so that the base 12 can be regarded as a casing, and the control switch 130a is exposed to the base 12.

Furthermore, the controller 130 is configured to control the level of energy, timing and pulse required for heating the electric heating tube 11, and the energy required for heating can be transmitted through the interval timing, pulse frequency, current magnitude or voltage level. Control is performed and transmitted to the electric heating pipe 11 via the controller 130.

Moreover, the power source 131 is a rechargeable battery that can be repeatedly charged and discharged to provide the power required for the heating tube 11 to be heated and the power required by the controller 130 during operation.

In addition, it should be understood that the wire 132 of the electronic control unit 13 is disposed through the power source 131, the controller 130, the base 12 and the fixing base 14 to connect the contact end 11b (or the electrode portions 111, 112). The contact 埠), so the mount 14 can be regarded as an electrical switch or socket.

When the heating device 1 is used, as shown in FIGS. 5A and 5B, a generally commercially available cigarette 9 is first inserted into the accommodating space S, and the filter 90 of the cigarette 9 protrudes from the opening 10a. The control switch 130a activates the controller 130 to transmit the current required for heating to the electric heating tube 11, and the electric heating tube 11 directly heats the tobacco 91 of the cigarette 9 to make the nicotine and other additions of the tobacco 91 heated. The flavor of the object is not leaked from the paper tube 9a of the surface of the cigarette 9, so that the user can directly suck through the filter 90 of the cigarette 9.

Therefore, the heating device 1 of the present invention is designed such that the electric heating tube 11 is disposed in the accommodating space S, so that the tobacco 91 of the cigarette 9 can be inserted into the electric heating. In the tube of the tube 11, a portion of the tobacco 91 is covered by the electric heating tube 11, and another portion of the tobacco 91 covers the periphery of the electric heating tube 11 so that the electric heating tube 11 directly heats the tobacco 91, so that The technology needs to indirectly heat the tobacco through the paper tube. The heating device 1 of the present invention can increase the contact area between the electric heating tube 11 and the tobacco 91, and shorten the heat transfer between the electric heating tube 11 and the tobacco 91 of the cigarette 9. The distance (such as the distance d between the circumferential surface of the electric heating tube 11 and the paper tube 9a shown in FIG. 5B is approximately equal to the radius r of the electric heating tube 11), so as to effectively reach a low temperature (between 160 degrees and 230 degrees Celsius, The purpose of heating the tobacco 91 is preferably between 200 and 230 degrees Celsius, so that the tobacco 91 is not required to be heated at a high temperature, thereby reducing unnecessary power consumption and improving the heating device 1 after a single charge. The number of times of smoking.

The low temperature heating means that the heating temperature is lower than 230 degrees Celsius, and the tobacco 91 can be effectively warmed for smoking. Specifically, in the general cigarette 9, an aqueous potassium citrate powder is often added as a cigarette combustion improver, and its boiling point is about 230 degrees Celsius. Therefore, if the heating temperature exceeds 230 degrees Celsius, the combustion-supporting agent on the surface of the tobacco leaves will be vaporized. The flavor of non-combustion heated cigarettes changes, so it is extremely important to control the heating temperature below 230 degrees Celsius.

Further, by the design of the opening end 11a, the electric heating tube 11 can be easily inserted into the tobacco 91 of the cigarette 9, and the tobacco 91 can be stuffed into the electric heating tube 11 by the inclined hole A.

Further, as shown in FIG. 5B, since the tobacco 91 of the cigarette 9 can be inserted into the tube of the electric heating tube 11 and the periphery of the electric heating tube 11, the electric heating tube 11 is used for the operation of heating the tobacco 91. An inner heating zone H1 and an outer heating zone H2 will be defined, and one half of the width W1 of the inner heating zone H1 will be defined. The width W2 of the outer heating zone H2 is substantially equal (i.e., 1⁄2 W1 = W2), so that the electric heating pipe 11 can perform equivalent low-temperature heating of the tobacco 91 in all directions. Further, the width W1 of the inner heating zone H1 and the width W2 of the outer heating zone H2 can be easily adjusted by the coaxial arrangement of the accommodating space S and the electric heating pipe 11 to heat the tobacco by the electric heating pipe 11. At 91 o'clock, the thermal conduction distance can be minimized, thereby meeting the high-efficiency, low-energy heating requirements.

In addition, since the air is a good thermal insulation layer, its thermal conductivity is extremely low (about 0.025 Wm ^-1 K ^-1 ), so the width W of the accommodating space S can be greater than the width D of the cigarette 9, as shown in Fig. 5A. It is shown that a space is formed between the carrier 10 and the paper tube 9a of the cigarette 9 as the air layer f1, so that the heat energy generated by the electric heating tube 11 is not lost. More preferably, the carrier 10 and the wall surface of the recess 120 have a spacing t such that the interval t acts as another air layer f2 to form a double heat insulating effect, so that when the user smokes the cigarette 9, There is no problem that the susceptor 12 is overheated due to the heating operation of the electric heating tube 11. It should be understood that the space t and the space between the carrier 10 and the cigarette 9 are used for heat insulation, so that the space and the interval t can be filled with appropriate heat insulating materials according to requirements, or can be required according to requirements. The effect of adding more air layers to enhance the heat insulation is not limited to the heat insulation mode of the above air layers f1, f2.

6A and 6B are side perspective views of other embodiments of the heating device 6a, 6b of the present invention.

As shown in Figures 6A and 6B, the heating device 6a, 6b includes at least one sensor 60, 61 for determining the position of the carrier 10.

In this embodiment, the sensors 60, 61 are disposed on the base 12 and electrically connected to the controller 130 to form an energy-saving control loop.

Furthermore, the sensor 60 is an acceleration detector embedded in the susceptor 12 without being exposed on the surface of the susceptor 12.

For example, when the user moves the pedestal 12 upward (such as near the lip of the face), the sensor 60 can detect the upward acceleration, and the controller 130 can instantaneously output high heating power, so that the heating device The temperature of 6a is higher than the preset smoking temperature, so that the electric heating tube 11 heats the smoking article, and the controller 130 continues to output power for a predetermined period of time after the heating power output is high.

On the other hand, when the user smokes the smoking article and holds the pedestal 12 downward (eg, away from the lip of the face), the sensor 60 detects the downward acceleration, so that the controller 130 is adjusted to be low. Heating the power causes the heating device 6a to enter an energy-saving standby state.

Alternatively, another sensor 61 exposed on the surface of the susceptor 12 may be added, which is a Face Proximity Sensor, such as an optical transmitting and receiving integrated inductive detector and a pyroelectric sensor. (Pyro-electric Infrared Radial Sensor) or ultrasonic sensor type detector, etc., but not limited to the above.

For example, when the user moves the pedestal 12 upward (such as near the lip of the face), the sensor 60 can detect the upward acceleration, and the controller 130 can instantaneously output high heating power, so that the heating device The temperature of 6b is higher than the preset smoking temperature, so that the electric heating tube 11 heats the smoking article, and if the other sensor 61 senses the condition that the face is close to the base 12, the control The heater 130 will continue to a high heating power for a period of time before dropping to a predetermined heating temperature.

It should be noted that if the sensor 60 detects an upward acceleration and the other sensor 61 does not sense that the face is close to the susceptor 12, the controller 130 will stop the high heating power output and adjust. The low heating power output (which is lower than the heating power required for the preset smoking temperature) causes the heating device 6b to enter an energy-saving standby state.

On the other hand, when the user smokes the smoking article, the sensor 60 detects the downward acceleration when the base 12 is moved downward (or when the other sensor 61 does not sense the face), The controller 130 is adjusted to a low heating power to bring the heating device 6b into an energy-saving standby state.

In summary, the heating device of the present invention is designed to directly heat the tobacco of the cigarette by the design of the carrier and the electric heating tube, without using a special cigarette or a special aerosol precursor carrier container, etc. The created heating device can heat the tobacco in a low temperature manner, so that it is easy to achieve the best effect of smoking the cigarette in a non-combustion manner, and the flavor of the nicotine and other additives produced by the cigarette is not leaked from the paper tube of the cigarette, Reduce the amount of second-hand smoke that others use.

Moreover, the heating device of the present invention can be heated at a low temperature, thereby improving the performance of the power source. Therefore, compared with the prior art, the heating device of the present invention is advantageous for continuously smoking the cigarette or increasing the time for smoking the cigarette.

The above embodiments are intended to illustrate the principles of the present invention and its effects, and are not intended to limit the present invention. Anyone who is familiar with this skill can repair the above embodiments without violating the spirit and scope of this creation. change. Therefore, the scope of protection of this creation should be as listed in the scope of patent application described later.
