Description

Cartridge and suction device

The present invention relates to a cartridge and a suction device.

In the past, there has been known a scented suction device for absorbing a fragrance without burning a material. Such a flavor absorber is known, for example, as an electronic cigarette. An electronic cigarette supplies an aerosol generated by atomization of a liquid containing a fragrance such as nicotine (corresponding to an example of an aerosol source) to a user's mouth, or a liquid containing no fragrance such as nicotine (equivalent to an aerosol) An example of the source is that the aerosol generated by atomization is supplied to the mouth of the user after passing through a source of flavor (for example, a source of tobacco).

The electronic cigarette includes a liquid tank or a reservoir containing a liquid for generating an aerosol, and a heater for atomizing the liquid. One of such electronic cigarettes has an insulating ring to insulate the wires from one of the connection heaters and the battery (see, for example, Patent Document 1).

Fig. 1 is an overall perspective view of a suction device according to the first embodiment. As shown in FIG. 1, the suction device 10 has a mouthpiece 11, a cartridge 20, and a battery unit 12. The cartridge 20 atomizes a liquid containing a fragrance (for example, a fragrance containing a component such as nicotine) to supply an aerosol toward the mouthpiece 11. The battery unit 12 supplies electric power to the cartridge 20 . The mouthpiece 11 guides the aerosol generated by the cartridge 20 into the mouth of the user. The mouthpiece 10 can replace the mouthpiece 11 and the cartridge 20 after a predetermined time of use. Further, it is also possible to replace only the cartridge 20 without replacing the mouthpiece 11. In the first embodiment, the mouthpiece 11 is provided with the mouthpiece 11, but the present invention is not limited thereto, and the mouthpiece 10 may not include the mouthpiece 11. Further, in the first embodiment, the cartridge 20 and the mouthpiece 11 are configured as separate members, but the cartridge 20 and the mouthpiece 11 may be integrally formed.

Fig. 2 is an exploded perspective view of the cartridge 20 shown in Fig. 1. As shown in FIG. 2, the cartridge 20 has a casing 30, a liquid holding member 40, a heater 50, and a cover 70. In addition to these, the cartridge 20 may include an outer casing (not shown) that houses the components inside. In this case, the parts shown in Fig. 2 constitute a part of the cartridge 20.

Fig. 3 is a perspective view of the cartridge 20 in a state in which the cover 70 is assembled to the outer casing 30. 4 is a perspective view of the cartridge 20 in a state in which the cover 70, the liquid holding member 40, and the heater 50 are assembled to the outer casing 30. Fig. 5 is a perspective view of the cartridge 20 in a state in which all the components are assembled. Fig. 6 is a side sectional view showing the cartridge 20 in a state in which all the components are assembled. Fig. 7 is a cross-sectional view of the cartridge 20 viewed from the direction of arrows 7-7 shown in Fig. 6. Hereinafter, the detailed configuration of the cartridge 20 will be described with reference to Figs. 2 to 7 . In the present specification, the term "longitudinal direction" refers to the direction in which the cartridge 20 and the battery portion 12 of the absorbing device 10 shown in Fig. 1 are arranged, and the short-side direction is substantially orthogonal to the longitudinal direction. direction. In addition, in the present specification, the upstream side refers to the side opposite to the air outflow port 34 based on the position of the heater 50 or the upstream side of the flow direction of the aerosol, and the so-called downstream side refers to the upstream side. The side closer to the air outflow port 34 or the downstream side in the flow direction of the aerosol is based on the position of the heater 50.

The outer casing 30 is a substantially cylindrical member that extends in the longitudinal direction of the cartridge 20, and is provided with a liquid tank 31 that can accommodate a liquid. In the present specification, the internal space of the liquid tank 31 is referred to as a housing space 31a (see FIG. 6). In the first embodiment, the outer casing 30 and the liquid tank 31 are integrally formed. However, the present invention is not limited thereto, and the outer casing 30 and the liquid tank 31 may be formed as individual components. The outer casing 30 has a casing body 30a and a mask member 60 attached to the casing body 30a. The casing body 30a has a partition member 36 constituting a part of the liquid tank 31. The partition member 36 is defined along the longitudinal direction: an air flow path defined by mounting the mask member 60 to the outer casing body 30a 62 (refer to Fig. 6) and the accommodating space 31a inside the liquid tank 31. The partition member 36 has a liquid supply port 32 for supplying a liquid to the accommodating space 31a inside the liquid tank 31. The liquid supply port 32 is opened in the short side direction of the cartridge 20, and the accommodating space 31a communicates with the air flow path 62. Further, the communication system referred to herein includes communication of a liquid and communication of a gas.

As shown in Fig. 2 and the like, the partition member 36 has a recess in which the liquid holding member 40 is fitted, and the liquid supply port 32 is formed in the recess. That is, the partition member 36 has a first surface 36a closest to the mask member 60 of the partition member 36, and a second surface 36b closer to the housing space 31a than the first surface 36a, and the liquid supply port 32 is formed. On the second side 36b. Further, the first surface 36a and the second surface 36b may have the same height. In this case, the liquid holding member 40 is disposed on the partition member 36 so as to cover the liquid supply port 32. The partition member 36 is configured to support the liquid holding member 40 that is fitted into the recess of the partition member 36. In the first embodiment, an example in which two liquid supply ports 32 are provided is disclosed. However, the present invention is not limited thereto, and the liquid supply port 32 may be provided in any number of one or more. When a plurality of liquid supply ports 32 are provided in the first embodiment, the partition member 36 separates a plurality of liquid supply ports 32.

The liquid tank 31 has an opening portion 33 that opens in the longitudinal direction of the cartridge 20 (see FIG. 7). The opening 33 is formed on the end surface of the liquid tank 31 on the side to which the battery unit 12 is connected. In the first embodiment, the opening area of the liquid supply port 32 is larger than the opening area of the opening 33. In other words, since the liquid supply port 32 is opened in the short-side direction, an opening area larger than the opening portion 33 opened in the longitudinal direction can be secured, and the liquid can be easily supplied into the liquid tank 31. In addition, in the case where there are a plurality of liquid supply ports 32, the liquid supply port 32 The opening area refers to the sum of the opening areas of the respective liquid supply ports 32.

Further, the outer casing 30 also has an air outflow opening 34 through which the aerosol passes. Specifically, in the first embodiment, the casing main body 30a has an air outflow port 34 on the end surface on the side connected to the mouthpiece 11. The air outflow port 34 is in communication with the mouthpiece 11. In the case where the mouthpiece 10 is not provided with the mouthpiece 11, the user can directly absorb the aerosol from the air outflow port 34. Further, in the first embodiment, the air outflow port 34 is formed in the casing main body 30a. However, the present invention is not limited thereto, and the air outflow port 34 may be partitioned from the casing member 60 by the casing body 30a by attaching the mask member 60 to The casing body 30a is formed. An air flow outlet 34 may also be formed in the mask member 60. In addition, the air outflow port 34 may be formed, for example, on the side of the outer casing 30. Furthermore, the casing body 30a has a notch portion 35 formed along the longitudinal direction of the cartridge 20. The notch portion 35 is covered by the mask member 60. The notch portion 35 is configured to expose the liquid holding member 40 and the heater 50 when not covered by the mask member 60.

The mask member 60 is a substantially plate-shaped member that extends in the longitudinal direction of the cartridge 20 . The mask member 60 has an air inflow port 61 penetrating the thickness direction thereof. The air inflow port 61 is provided at a position facing the partition member 36 and the heater 50 of the casing body 30a. In the first embodiment, the air inflow ports 61 are provided in plural at substantially equal intervals along the longitudinal direction of the mask member 60. However, the air inflow port 61 may be a single one. The mask member 60 forms an air flow path 62 together with the case body 30a (see FIGS. 6 and 7; an example of a space), and the heater 50 and the liquid holding member 40 are housed in the air flow path 62. Air inflow 61 and air outflow The port 34 is in communication through the air flow path 62. Further, in the present embodiment, the air inflow port 61 is configured to directly open to the atmosphere and introduce external air. However, the present invention is not limited thereto, and the outer casing 30 may be provided to surround the outer casing, and the air in the outer casing may be introduced. In this case, the outer casing 30 and the outer casing may each have a mechanism that engages with the battery portion 12. Alternatively, the outer casing 30 may have a mechanism that engages with the battery unit 12, and the outer casing 30 presses the outer casing 30 against the battery unit 12 to engage the outer casing 30 with the battery unit 12.

The liquid holding member 40 is a porous member formed of, for example, cotton, glass fiber, or porous ceramic. In the present specification, the term "liquid holding member" means a porous member that does not have a self-heating function. As shown in FIG. 4, the liquid holding member 40 is provided in the cartridge 20 in such a manner as to cover the liquid supply port 32 of the partition member 36. In other words, the liquid retaining member 40 is laminated on the partition member 36 and supported by the partition member 36. The liquid contained in the liquid tank 31 comes into contact with the liquid holding member 40, is absorbed by the liquid holding member 40, and is held in the liquid holding member 40. In other words, the liquid holding member 40 sucks the liquid contained in the liquid tank 31 toward the heater 50. The area of the liquid holding member 40 facing the liquid supply port 32 is preferably larger than the opening area of the liquid supply port 32. In this way, not only the entire opening area of the liquid supply port 32 can be surely covered by the liquid holding member 40, but also the liquid holding member 40 can be easily supported by the partition member 36.

The heater 50 is substantially U-shaped as a whole, and is disposed on the opposite side of the liquid supply port 32 with the liquid holding member 40 interposed therebetween. In other words, the heater 50 is disposed in the liquid holding member 40 as shown in FIGS. 6 and 7 Between the mask members 60. The shape of the heater 50 is not limited to a U shape, and may be, for example, a line shape or a surface shape. Specifically, the heater 50 may have an I-shape or a form in which a plurality of I-shaped heaters are connected to each other by a lead wire. In the case where the heater 50 is planar, it is preferable to arrange the end surface (planar portion) in contact with the liquid holding member 40.

The heater 50 is preferably made of a porous metal such as a porous metal, but is not limited thereto. The material of the porous metal used for the heater 50 is not particularly limited as long as it can be used as a wick for atomizing the liquid to be held by electric heating when the user sucks. limits. The heater 50 may be a porous metal body containing, for example, nickel, nichrome, stainless steel (SUS) or the like. Further, ceramics such as tantalum carbide (SiC) may be used as long as the conductive material can generate heat when electric power is applied. The heater 50 in the first embodiment has a three-dimensional mesh structure. The three-dimensional mesh structure is a structure that contains voids and at least a portion of the voids communicate, that is, has an open pore structure. The heater 50 of the first embodiment has a function of attracting a liquid by a capillary phenomenon. For the porous metal body having such an open pore structure, for example, Celmet (registered trademark) manufactured by Sumitomo Electric Industries, Ltd. is mentioned. Celmet is a porous metal body containing nickel (Ni) or a porous metal body containing an alloy of nickel and chromium (Cr). Further, the heater 50 may be formed by arranging a plurality of wires including, for example, nickel, nichrome, stainless steel (SUS) or the like on the liquid holding member 40 in a mesh shape or in parallel with each other.

At least a portion of the heater 50 is configured to be in contact with or in proximity to the liquid holding member 40 to heat the liquid holding member 40. The liquid produces an aerosol. When the heater 50 is made of a porous metal, the heater 50 contacts the liquid holding member 40, and the heater 50 absorbs the liquid from the liquid holding member 40 and holds it, thereby heating the liquid held by the heater and efficiently angering the property. Sol. Further, when the heater 50 is made of a porous metal, the liquid holding member 40 may not be provided in the cartridge 20. In this case, the heater 50 has a function of holding a liquid in addition to the function as a heating element. Therefore, the heater 50 is disposed in the concave portion of the partition member 36 to heat the planar porous metal. The device 50 covers the liquid supply port 32 instead of the liquid holding member 40. In addition, when the liquid holding member 40 is porous and rigid, such as porous ceramics, a heater such as platinum or palladium may be provided in the liquid holding member 40 in a predetermined pattern by means of, for example, printing or vapor deposition. on.

The heater 50 has a pair of lead wires 51 (corresponding to an example of a conductor) for connecting to the battery unit 12. The lead wires 51 are housed in a pair of housing portions 76 of a cover 70 which will be described later. The heater 50 has a blocking portion 52 that is provided to be branched from the lead wires 51. When the lead wire 51 is housed in the accommodating portion 76, the latching portion 52 is caught on the second surface 72 of the cover 70, which will be described later, and the heater 50 is prevented from moving toward the mouthpiece 11 (air flow outlet 34 side) in the longitudinal direction. Alternatively, the latching portion 52 may be formed to be engaged with the first surface 71 of the cover 70, which will be described later. In this case, it is possible to suppress the heater 50 from moving toward the battery unit 12 side in the longitudinal direction. The latching portion 52 can also be formed by bending the end portion of the lead wire 51 as shown in FIGS. 22 and 23 to be described later.

Next, the cover 70 will be described in detail. As shown in Fig. 2, the cover 70 is configured to be attachable and detachable with respect to the cartridge 20. that is, The cover 70 is configured as a separate component from the components constituting the cartridge 20. Therefore, the cover 70 and the outer casing 30 of the cartridge 20 can be made of different materials. For example, the cover 70 may be formed of a flexible material so that the cover 70 can be easily attached and detached with respect to the cartridge 20, and the outer casing 30 can be formed of a non-flexible material (a material having high rigidity) to increase the strength of the outer casing 30. In one embodiment, the cover 70 can be configured, for example, integrally with the outer casing 30 or the liquid reservoir 31. Further, the cover 70 is preferably made of an insulating material such as plastic or a material having insulating properties and flexibility such as silicone. As shown in FIGS. 2 to 7, the cover 70 is disposed between the liquid tank 31 and the battery unit 12 shown in FIG. 1 in the longitudinal direction of the cartridge 20. Alternatively, in other words, the cover 70 is provided in the middle of the circuit connecting the heater 50 and the conductor of the battery unit 12. The cover 70 is configured to seal at least a portion of the space in the liquid tank 31. Specifically, the cover 70 is configured to seal the opening portion 33 of the liquid tank 31 when attached to the cartridge 20 .

As shown in Fig. 2, the cover 70 has a first surface 71, a second surface 72 opposite to the first surface 71, and a cover side surface 73. The cover side 73 is connected to the outer peripheral edge of the first surface 71 and the outer peripheral edge of the second surface 72. The cover 70 of the first embodiment has a substantially plate shape as a whole, but the shape is not limited thereto.

Fig. 8 is a front view of the first face 71 side of the cover 70. As shown in Fig. 8, the cover 70 is attached to the first surface 71 with a sealing region 74 that seals at least a portion of the space within the liquid reservoir 31. The sealing region 74 is constituted by a portion that contacts the edge of the opening portion 33 where the liquid groove 31 is formed and a portion that blocks the opening portion 33. In addition, the cover 70 is attached to the sealing area of the first surface 71. The field 74 has a substantially D-shaped projection 75 in the front view shown in FIG. When the cover 70 is attached to the cartridge 20, the projection 75 is fitted into the opening 33 of the liquid tank 31 to improve the sealing property of the cover 70. That is, as shown in Fig. 7, in the first embodiment, the shape of the opening portion 33 has a D-shaped opening corresponding to the shape of the projection 75.

As shown in FIGS. 2 to 8, the cover 70 has a pair of lead wires 51 for accommodating the heater 50 to the accommodating portion 76. In the first embodiment, the accommodating portion 76 accommodates the pair of lead wires 51. However, the accommodating portion 76 may accommodate any of the electric conductors constituting a part of the circuit between the heater 50 and the battery unit 12. The conductor in the present specification includes, for example, a part of the heater 50, a lead 51 connected to the heater 50, a lead (not shown) connected to the battery unit 12, a lead 51 connecting the heater 50, and the battery unit 12. A lead wire (connector), a terminal of the heater 50, a terminal of the battery unit 12, and a combination of the above are used to electrically connect any of the electric conductors of the heater and the battery unit. As shown in FIG. 8, the accommodating portion 76 is provided outside the sealing region 74. In other words, the receiving portion 76 is disposed not in the sealing region 74 on the surface of the cover 70. Therefore, any conductor (for example, the lead wire 51) accommodated in the accommodating portion 76 does not affect the sealing region 74 of the opening portion 33 of the sealing liquid tank 31. In other words, since the conductor does not pass through the sealing region 74, it is not necessary to provide a hole or the like through which the conductor passes through the sealing region 74, and it is possible to more reliably prevent the liquid from leaking out of the liquid tank 31.

The accommodating portion 76 is provided on at least a part of the side surface 73 of the cover. In the first embodiment, the accommodating portion 76 has a configuration formed on the side surface 73 of the cover and penetrating from the first surface 71 to the concave portion of the second surface 72. More As shown in FIG. 8, the accommodating portion 76 in the form of the recess is recessed toward the center side of the cover 70 with respect to the outer peripheral surface 73a of the cover side surface 73. In other words, the accommodating portion 76 is formed to recess the cover 70 substantially in the direction toward the center when viewed from the front view of Fig. 8. The pair of leads 51 are housed in the accommodating portion 76 so that at least a part of the cover side surface 73 is in contact with one of the connection heater 50 and the battery portion 12 to the conductor. In other words, since the cover 70 does not have a hole through which the electric conductor connecting the heater 50 and the battery portion 12 passes, a pair of electric conductors pass through the outer peripheral surface side of the cover 70.

The cover 70 of the first embodiment has a positional relationship as described below between the sealing region 74 and the accommodating portion 76. That is, as shown in FIGS. 6 to 8, when the sealing area 74 of the first surface 71 of the cover 70 is distinguished from the other area by the virtual plane P1 which is parallel to the longitudinal direction of the cartridge 20, In the plane P1, the liquid tank 31 is located on the side of the sealing area 74, and the housing portion 76 and the heater 50 are located on the opposite side of the sealing area 74 as compared with the plane P1. That is, in the cover 70 of the first embodiment, since the sealing region 74 and the accommodating portion 76 have a positional relationship which is clearly distinguished by one plane P1, the accommodating portion 76 does not affect the sealing region 74, and can be more reliably prevented. The liquid leaking from the liquid tank 31 due to the accommodating portion 76.

Next, the assembly procedure of the cartridge 20 will be described. First, as shown in FIG. 3, the opening portion 33 of the liquid tank 31 is closed by the cover 70. Thus, the sealing portion 74 of the cover 70 seals the opening portion 33 to prevent liquid from leaking from the opening portion 33. Next, the liquid as the aerosol source is supplied from the liquid supply port 32 into the accommodating space 31a. Then, as shown in Figure 4, keep the liquid The member 40 is configured to cover the form of the liquid supply port 32. Since the partition member 36 has a concave portion due to the difference between the first surface 36a and the second surface 36b, even if some of the micro liquid overflows from the liquid supply port 32 of the liquid tank 31, the liquid remains in the concave portion. The liquid holding member 40 is disposed to cover the form of the liquid supply port 32, and the liquid holding member 40 holds the liquid while preventing the liquid from leaking out of the liquid tank 31. In other words, the cartridge 20 can hold a larger amount of liquid than the liquid tank 31 by the liquid holding member 40.

On the other hand, when liquid is supplied to the accommodating space 31a through the opening portion 33 after the liquid supply member 40 is disposed to cover the liquid supply port 32, there is a gap between the liquid holding member 40 and the liquid supply port 32, or a liquid The possibility of the member 40 being held out is leaked. In addition, in this case, since the cover 70 is attached to the opening portion 33 after the liquid is supplied to the accommodating space 31a, when the opening portion 33 is closed by the cover 70, the pressure in the accommodating space 31a rises and the liquid may be promoted. It leaks from the liquid supply port 32. Therefore, in the present embodiment, the liquid is supplied into the accommodating space 31a after the opening portion 33 is closed by the lid 70, and liquid can be prevented from leaking out of the liquid tank 31.

Further, as described above, the heater 50 is made of a porous metal, and the liquid holding member 40 may not be provided in the cartridge 20. In this case, the heater 50 is made of a planar porous metal instead of the liquid holding member 40, and the heater 50 is disposed in the concave portion of the partition member 36 so as to cover the liquid supply port 32. Moreover, in this case, since the heater 50 is in direct contact with the outer casing 30 (the partition member 36 in the first embodiment), the contact portion of the outer casing 30 can be formed with a heat resistant material, or covered with a heat resistant material. The contact portion of the cover 30 is covered.

Next, the heater 50 is disposed above the liquid holding member 40. At this time, the lead wire 51 of the heater 50 is housed in the accommodating portion 76. In other words, the lead 51 of the heater 50 is caught in the accommodating portion 76 of the cover 70, and the heater 50 is brought into contact with the surface of the liquid holding member 40. Since the accommodating portion 76 has a shape of a recess formed in the side surface 73 of the cover, the lead wire 51 can be easily disposed from the side surface of the cover 70 to the accommodating portion 76.

Finally, as shown in FIGS. 5 to 7, the mask member 60 is attached to the casing body 30a to cover the notch portion 35. As a result, the assembly of the cartridge 20 is completed. In the state in which all the components of the cartridge 20 are assembled, as shown in Figs. 6 and 7, the air flow path 62 is defined by the mask member 60 and the casing body 30a. When electric power is supplied to the heater 50, the liquid held in the liquid holding member 40 is heated to generate an aerosol. In the case where the heater 50 can be used as a heater having both the function of the wick, the liquid held in the heater 50 is heated to generate an aerosol. When the user inhales from the mouthpiece 11, the air that has flowed in from the air inflow port 61 of the mask member 60 flows out of the air outflow port 34 together with the aerosol existing in the air channel 62 through the air channel 62. The aerosol is supplied to the mouth of the user.

As described above, the cover 70 of the cartridge 20 has a sealing region 74 and a housing portion 76 provided on the outer side of the sealing region 74. Therefore, it is not necessary to provide a hole or the like for holding the conductor (for example, the lead 51) housed in the accommodating portion 76 inside the sealing region 74. Therefore, it is possible to more reliably prevent the liquid in the liquid tank 31 from leaking to the battery unit 12 side through the accommodating portion 76.

Further, in the cartridge 20 of the present embodiment, the liquid supply port 32 The opening is opened in the short side direction, and the accommodating portion 76 is provided on at least a part of the cover side surface 73 of the cover 70. Therefore, when the liquid holding member 40 and the heater 50 are assembled to the cartridge 20, the liquid holding member 40 can cover the liquid supply port 32 from the short side direction, and the lead wire 51 can be disposed in the housing portion 76 from the side surface of the cover 70. Therefore, the liquid holding member 40 and the heater 50 can be easily assembled to the cartridge 20 as compared with the case where the lead wire 51 is formed in the through-hole-shaped accommodating portion formed in the longitudinal direction.

Further, in the cartridge 20 of the present embodiment, the pair of leads 51 are arranged to be electrically connected to each other without being electrically connected to each other. Specifically, in the present embodiment, the lead wires 51 are respectively housed by the pair of housing portions 76. However, the number of the accommodating portions 76 may be one. In this case, the pair of lead wires 51 are housed in one accommodating portion 76 so as not to be electrically connected to each other. Alternatively, the pair of leads 51 may be covered with an insulating material so that the two are not in electrical contact with each other. The shape of the accommodating portion 76 may be any shape capable of accommodating the electric conductor.

Further, the cover 70 of the first embodiment has a substantially plate shape including the first surface 71, the second surface 72, and the cover side surface 73. However, if the housing portion 76 is provided outside the sealing region 74, Then the shape is not limited to the above. For example, the cover 70 may have any shape such as a spherical shape or a cylindrical shape in which the end surface is spherical. Further, in the cartridge 20 of the first embodiment, the lead wire 51 of the heater 50 is disposed in the housing portion 76 of the cover 70. However, the present invention is not limited thereto, and the heater 50 and the lead 51 may be disposed in the housing portion 76. A separate conductor (e.g., a connector member or the like) is connected to the lead 51 of the heater 50. That is, in this case, the conductor is For example, the connector member is disposed between the first face 71 and the second face 72 of the cover 70.

Next, the positional relationship between the accommodating space 31a in the short-side direction of the cartridge 20 shown in FIGS. 2 to 8, the air flow path 62, the partition member 36, the heater 50, the air inflow port 61, and the air outflow port 34 will be described. As shown in FIGS. 2 to 6, the cartridge 20 has an air inflow port 61 (mask member 60), an air flow path 62, a partition member 36, and a housing space 31a of the liquid tank 31 in the short side direction. . The heater 50 is disposed between the air inflow port 61 and the partition member 36 and disposed in the air flow path 62.

Fig. 9 is a view showing the cartridge 20 of the first embodiment from the end surface on which the air outflow port 34 is provided. As described with reference to Fig. 6, when the user inhales from the mouthpiece 11 or the air outflow port 34, the air that has flowed in from the air inflow port 61 of the mask member 60 flows through the air channel 62 to the air outflow port 34. At this time, in order to efficiently transfer the aerosol generated by the heater 50 to the air outflow port 34 by the air flowing in from the air inflow port 61, the air flowing in from the air inflow port 61 passes through the vicinity of the heater 50 or It is preferable that the internal form flows through the air flow path 62. In other words, when the air flowing in from the air inflow port 61 does not pass through the vicinity or inside of the heater 50 and flows to the air outflow port 34, the air system cannot sufficiently contain the aerosol suspended in the vicinity of the heater 50. On the other hand, in the first embodiment, as shown in FIG. 9, when viewed in the longitudinal direction, the position of the air outflow port 34 in the short-side direction is partially overlapped with the position of the heater 50 in the short-side direction.

Moreover, as shown in FIG. 6, the heater 50 is at least one. It is preferable that the portion is located at the same position as any of the air inflow ports 61 along the longitudinal direction, or is located closer to the air outflow port 34 than any of the air inflow ports 61. In other words, in the longitudinal direction of the heater 50 shown in Fig. 6, the end portion close to the air outflow port 34 is used as the first end portion 50b, and the end portion away from the air outflow port 34 is used as the second end portion 50c. It is preferable that at least one of the air inflow ports 61 is provided on the upstream side of the first end portion 50b of the heater 50 in the longitudinal direction. Further, the air inflow port 61 may be provided on the upstream side of the second end portion 50c of the heater 50 at the position in the longitudinal direction. Further, the air outflow port 34 herein does not mean the opening of the air outlet 34 exposed to the outside of the cartridge 20, but refers to the boundary between the air flow path 62 and the air outflow port 34, that is, the air outflow port 34. It faces the opening of the air flow path 62.

For example, when the position of the airflow outlet 34 in the short-side direction is closer to the airflow inlet 61 than the position of the heater 50 in the short-side direction, the air flowing in from the airflow inlet 61 passes through the shortest distance from the airflow outlet 34. The passage is difficult to access the heater 50. On the other hand, when the air outflow port 34 and the heater 50 are in the positional relationship shown in FIG. 9, at least a part of the heater 50 is disposed in the air flowing in from the air inflow port 61 to flow out from the air outflow port 34. Since the air flow path 62 is in the air flow, the air from the air flow inlet 61 is more likely to contact the heater 50.

The positional relationship between the air outflow port 34 and the short side direction of the heater 50 is not limited to this. Fig. 10 is a side cross-sectional view showing the cartridge 20 of an example in which the air flow outlet 34 and the heater 50 are in other positions. As shown in Fig. 10, in the cartridge 20, the air outlet 34 is heated in the short side direction. The device 50 is closer to the side of the accommodating space 31a. Specifically, the end portion 34a of the air outflow port 34 near the air inflow port 61 is in the short side direction, and is located closer to the accommodating space 31a than the upper end portion 50a of the heater 50 near the air inflow port 61 side. In the example shown in Fig. 10, the upper end portion 34a of the air outflow port 34 near the air inflow port 61 is in the short side direction, and is closer to the receiving end than the lower end portion 50d of the heater 50 away from the air inflow port 61 side. Space 31a side.

When the air outlet 34 and the heater 50 are in the positional relationship shown in FIG. 10, the upper end portion 34a of the air outflow port 34 is located closer to the accommodating space 31a than the lower end portion 50d of the heater 50 in the short-side direction. The air of the air inflow port 61 easily contacts the heater 50. Therefore, the aerosol generated by the heating of the heating unit 50 can be efficiently delivered to the air outflow port 34.

Next, other examples of the mask member 60 shown in Figs. 2 to 10 will be described. 11 and 12 are plan views showing other forms of the mask member 60. As shown in Fig. 11, the mask member 60 has a plurality of air inflow ports 61 provided along the longitudinal direction. Further, the mask member 60 shown in Fig. 12 has a single air inflow port 61 provided along the longitudinal direction.

When the opening areas of the plurality of air inflow ports 61 are the same, when the user inhales from the mouthpiece 11 (refer to FIG. 1) or the air outflow port 34, the air inflow from the air inflow port 61 located in the vicinity of the air outflow port 34 flows. The amount of air will be larger than the amount of air flowing in from the air inflow port 61 located far from the air outflow port 34. On the long side of a single air inlet 61 The same applies to the case where the area per unit length is constant. When the user inhales from the mouthpiece 11 (see FIG. 1) or the air outflow port 34, the user flows in from the portion of the air inflow port 61 located in the vicinity of the air outflow port 34. The amount of air will be larger than the amount of air flowing from the air inflow port 61 located farther from the air outflow port 34.

On the other hand, the air inflow port 61 shown in Figs. 11 and 12 is formed such that the closer to the air outflow port 34, the smaller the opening area. In other words, the area of the air inflow port 61 near the air outflow port 34 side is smaller than the area of the air inflow port 61 away from the air outflow port 34 side. Therefore, the amount of air flowing in from each of the plurality of air inflow ports 61 or the amount of air flowing in from the respective positions in the longitudinal direction of the single air inflow port 61 can be made uniform. As a result, air can be brought into contact with the entirety of the heater 50, and the aerosol can be efficiently transported.

Next, the shape of the partition member 36 of the cartridge 20 shown in Figs. 2 to 8 will be described in detail. Figure 13 is a plan view of the partition member 36. As shown in Fig. 13, the partition member 36 has a downstream side end portion 36e located closest to the air outflow port 34 side and an upstream side end portion 36f located farthest from the air outflow port 34 side. As shown in Fig. 6, the downstream side end portion 36e is an end portion in contact with the outer casing 30 in the longitudinal direction, and the upstream side end portion 36f is an end portion in contact with the cover 70. Further, the liquid supply port 32 of the partition member 36 has a downstream side opening edge portion 36c located closest to the air outflow port 34 side and an upstream side opening edge portion 36d located farthest from the air outflow port 34 side. Further, as shown in Fig. 13, the downstream side opening edge portion 36c in the case where there are a plurality of liquid supply ports 32 is located at the lowermost of the plurality of liquid supply ports 32 The upstream side opening edge portion 36d is an opening edge on the most upstream side among the plurality of liquid supply ports 32. Further, the partition member 36 has an upstream portion 36h between the upstream side opening edge portion 36d and the upstream side end portion 36f of the liquid supply port 32, and a downstream side opening edge portion 36c and a downstream side of the liquid supply port 32. The downstream portion 36g between the ends 36e.

In the present embodiment, as shown in Fig. 13, the liquid supply port 32 is formed in the partition member 36 in such a manner that the entire upstream side is on the upstream side. More specifically, the liquid supply port 32 is such that the distance L2 between the upstream side opening edge portion 36d of the liquid supply port 32 and the upstream side end portion 36f of the partition member 36 is larger than the downstream side opening edge portion 36c of the liquid supply port 32. The distance L1 between the downstream side end portion 36e of the partition member 36 is smaller, and is formed in the partition member 36. The distance L2 between the upstream side opening edge portion 36d of the liquid supply port 32 and the upstream side end portion 36f of the partition member 36 may be referred to as the length in the longitudinal direction of the upstream portion 36h of the partition member 36. Similarly, the distance L1 between the downstream side opening edge portion 36c of the liquid supply port 32 and the downstream side end portion 36e of the partition member 36 can be referred to as the length in the longitudinal direction of the downstream portion 36g of the partition member 36. Therefore, the length of the upstream portion 36h in the longitudinal direction is shorter than the length of the downstream portion 36g in the longitudinal direction.

Fig. 14 is a plan view of the partition member 36, the liquid holding member 40, and the heater 50. As shown in Fig. 14, the liquid holding member 40 is disposed in the recess of the partition member 36, and the heater 50 is disposed on the liquid holding member 40. The heater 50 has a first end portion 50b (corresponding to an example of the downstream side heater end portion) located closest to the air outflow port 34 side, and a second end portion 50c located on the side farthest from the air outflow port 34 (equivalent to An example of the upstream heater end).

In the present embodiment, as shown in Fig. 14, the heaters 50 are also disposed on the upstream side as a whole. More specifically, the distance L4 between the second end portion 50c and the upstream side end portion 36f of the partition member 36 is smaller than the distance L3 between the first end portion 50b and the downstream side end portion 36e of the partition member 36. .

The suction device 10 shown in Fig. 1 is held by the user: when the user inhales from the mouthpiece 11, the cartridge 20 is usually positioned lower than the mouthpiece 11, that is, the posture of the upstream side is below. . Therefore, if the liquid supply port 32 is provided on the downstream side, the position of the liquid supply port 32 when the suction device 10 is used is located higher than the case where the liquid supply port 32 is biased toward the upstream side. In this case, when the suction device 10 is used, the liquid in the liquid tank 31 is retained on the upstream side (lower side) by gravity. Therefore, when the liquid in the liquid tank 31 becomes small, it is difficult for the liquid to contact the liquid holding member 40.

On the other hand, when the liquid supply port 32, the liquid holding member 40, and the heater 50 are provided integrally across the longitudinal direction of the partition member 36, the heater 50 is disposed close to the air outflow port 34. In this case, the aerosol generated in the vicinity of the first end portion 50b of the heater 50 is introduced into the air outflow port 34 without being sufficiently cooled, and is still in a high temperature, and reaches the user's mouth. Further, in the case where the liquid supply port 32, the liquid holding member 40, and the heater 50 are integrally provided across the longitudinal direction of the partition member 36, when the liquid in the liquid tank 31 becomes small, the liquid system is difficult to be held by the liquid holding member. Partial absorption of the downstream side (upper side) of 40. That is, the liquid system is easily maintained at the portion on the upstream side (lower side) of the liquid holding member 40, and thus heat near the first end portion 50b of the heater 50 may be difficult to assist in the aerosol. It is produced to reduce efficiency.

Therefore, in the first embodiment, as shown in Fig. 10, the liquid supply port 32 is disposed so as to be entirely on the upstream side, so that the liquid supply port 32 is located below when the suction device 10 is used. When the suction device 10 is used, the liquid in the liquid tank 31 is retained on the upstream side (lower side) by gravity, so that even if the liquid in the liquid tank 31 is small, the liquid holding member 40 can be made to pass through the liquid supply port 32. Maintain liquids efficiently. Therefore, the heater 50 can be used to efficiently heat the liquid as a whole to generate an aerosol.

Further, in the first embodiment, since the liquid supply port 32 and the heater 50 are not provided on the downstream side of the partition member 36, the aerosol generated by the heater 50 can be extended to reach the air outflow port 34 (refer to the second The distance to 8). As a result, the distance that the generated aerosol reaches the mouth of the user becomes longer, and the time for cooling the aerosol can be prolonged.

As shown in Figs. 13 and 14, the area of the surface of the liquid holding member 40 facing the liquid supply port 32 is smaller than the surface of the partition member 36 where the liquid supply port 32 is provided (in the first embodiment, the first portion is included) The area of the face 36a and the face of the second face 36b is preferably. In this way, the amount of moisture retention per unit area of the liquid holding member 40 can be sufficiently ensured, and the heater 50 and the liquid supply port 32 are positioned at opposite positions with the liquid holding member 40 interposed therebetween, so that the liquid can be directly supplied to the liquid holding member. The portion of the 40 which is easily heated by the heater 50 can suppress the drying of the liquid (aerosol source) held in the liquid holding member 40 during the heating of the heater 50.

Next, other examples of the cover 70 shown in Figs. 2 to 8 will be described. Fig. 15 is a perspective view showing another form of the cover 70. As shown in Fig. 15, the cover 70 has a shape different from that of the cover 70 shown in Figs. 2 to 8. That is, the cover 70 shown in Fig. 15 has a shape in which the first surface 71 and the second surface 72 are formed in a substantially semicircular shape, and has two receiving portions 76 on the side surface 73 of the cover. Specifically, the accommodating portion 76 of the cover 70 has a pair of ridge portions 78 projecting from the cover side surface 73, respectively. A recess is formed between the pair of ridges 78, and the recess 51 is housed in the lead 51 of the heater 50 shown in Fig. 2 and the like. Thereby, the pair of lead wires 51 are disposed apart from each other in such a manner as not to be in electrical contact with each other. In addition, three ridge portions 78 may be provided on the side surface 73 of the cover. In this case, two housing portions 76 are formed between the three rib portions 78. Further, the number of the accommodating portions 76 may be one. In this case, the pair of lead wires 51 are housed in one accommodating portion 76 so as not to be in electrical contact with each other.

The cover 70 shown in Fig. 15 is also the same as the cover 70 shown in Figs. 2 to 8, because the accommodating portion 76 is provided outside the sealing portion 74, so that the liquid in the liquid tank 31 can be more reliably prevented from passing through the accommodating portion 76. It leaks to the side of the battery unit 12. Further, since the accommodating portion 76 is provided on at least a part of the cover side surface 73 of the cover 70, the lead wire 51 can be placed in the accommodating portion 76 from the side surface of the cover 70, and the heater 50 can be easily assembled to the cartridge 20. Furthermore, since the shape of the cover 70 shown in Fig. 15 is a substantially semicircular plate-like body, when the cover 70 is assembled to the cartridge 20, the cover member 60 and the outer casing 30 can be enlarged. The area of the air flow path in which the internal space 62 communicates with the space on the side of the battery unit 12. Therefore, for example, the air inflow port is provided on the upstream side (the battery unit 12 side) closer to the cover 70, so that air can be supplied from the upstream side of the cover 70 to the internal space 62. In this case, no An air inflow port 61 is provided in the mask member 60.

Further, in the cover 70 shown in FIG. 15, an individual conductor (for example, a connector member) separate from the heater 50 and the lead 51 may be disposed in the housing portion 76, and the conductor and the heater 50 may be disposed. The leads 51 are connected. That is, in this case, a conductor (for example, a connector member) is disposed between the first surface 71 and the second surface 72 of the cover 70.

Fig. 16 is a perspective view showing another form of the cover 70. As shown in Fig. 16, the cover 70 has a shape different from that of the cover 70 shown in Figs. 2 to 15 . That is, the accommodating portion 76 of the cover 70 shown in Fig. 16 has a shape that penetrates the hole between the first surface 71 and the second surface 72. Further, the housing portion 76 of the cover 70 houses a connector member 79 (corresponding to an example of a conductor) extending between the first surface 71 and the second surface 72. The connector member 79 is configured such that one end thereof is connected to the lead 51 of the heater 50, and the other end is connected to a lead or terminal (not shown) of the battery unit 12, and the lead 51 and the battery unit 12 are electrically connected.

When the cover 70 shown in Fig. 16 is used for the cartridge 20, the lead 51 of the heater 50 is formed to be slightly shorter than the lead 51 shown in Figs. 2 to 7. When the heater 50 is placed on the liquid holding member 40, the lead 51 is brought into contact with or connected to the end of the connector member 79 provided on the cover 70. Thereby, the lead wire 51 is electrically connected to the battery unit 12.

The cover 70 shown in Fig. 16 is also provided with the accommodating portion 76 on the outer side of the sealing region 74 in the same manner as the cap 70 shown in Figs. 2 to 15, so that the liquid in the liquid tank 31 can be more reliably prevented from passing through. The portion 76 leaks to the side of the battery portion 12. Also, the cover 70 shown in Fig. 16 Since the connector member 79 disposed in the accommodating portion 76 is provided, the heater 50 can be easily assembled to the cartridge 20 in a state of being electrically connected to the battery portion 12. As shown in Fig. 16, when the connector member 79 has a length protruding from the first surface 71 and the second surface 72 of the cover 70, a recess or the like may be provided at the end of the connector member 79 so as to be detachable from the cartridge The lead wire 51 is connected in the short side direction of 20. In this case, when the liquid holding member 40 and the heater 50 are assembled to the cartridge 20, the liquid supply port 40 can be covered from the short side by the liquid holding member 40, and then the lead 51 can be connected to the connector member 79 from the short side direction. . Therefore, the liquid holding member 40 and the heater 50 can be assembled to the cartridge 20 more easily. Further, the connector member 79 shown in Fig. 16 has a length protruding from the first surface 71 and the second surface 72 of the cover 70, but may be accommodated in the housing portion 76 for example, having a length accommodated in the housing portion 76. Inside. In this case, the end of the lead 51 of the heater 50 is inserted into the accommodating portion 76, and the end portion of the lead 51 is guided by the accommodating portion 76 to the connector member 79 so that the end portion of the lead 51 comes into contact with the connector member 79. Or connect.

Fig. 17 is a perspective view showing another form of the cover 70. Fig. 18 is a front view seen from the side of the second face 72 of the cover of Fig. 17. Figure 19 is a side cross-sectional view of the cover of Figure 17. As shown in Fig. 17, in the cover 70, the first surface 71 has a sealing region 74, and the first surface 71 and the second surface 72 are formed in a substantially semicircular shape. When viewed from the side cross section shown in FIG. 19, the accommodating portion 76 has a shape that penetrates the substantially L-shaped hole of the cover side surface 73 and the second surface 72.

As shown in FIG. 19, the receiving portion 76 of the cover 70 houses a connector member extending between the side surface 73 of the cover and the second surface 72. 79 (corresponding to an example of a conductor). The connector member 79 is configured such that one end thereof is connected to the lead 51 of the heater 50, and the other end is connected to a lead or terminal (not shown) of the battery unit 12, and the lead 51 and the battery unit 12 are electrically connected. In the illustrated example, the connector member 79 is configured to protrude from the hole of the accommodating portion 76. However, the present invention is not limited thereto, and the end portion of the connector member 79 may be formed in the accommodating portion 76. Further, the illustration of the connector member 79 is omitted in the cover 70 shown in Figs.

When the cover 70 shown in FIG. 17 is used for the cartridge 20, when the heater 50 is placed on the liquid holding member 40, the lead 51 is in contact with the end of the connector member 79 provided at the cover 70 or connection. The lead or terminal (not shown) of the battery unit 12 is electrically connected to the end of the connector member 79 on the second surface 72 side, whereby the lead 51 and the battery unit 12 are electrically connected. Further, in a case where the end portion of the connector member 79 is located in the accommodating portion 76, when the heater 50 is placed on the liquid holding member 40, the end portion of the lead wire 51 is formed in the side surface 73 of the cover. In the hole of the accommodating portion 76, the lead wire 51 is formed in an L shape. Thereby, the lead wire 51 is brought into contact with or connected to the end of the connector member 79, and the lead wire 51 is electrically connected to the battery portion 12.

Also in the cover 70 shown in Fig. 17, as in the cover 70 shown in Figs. 2 to 16, the accommodating portion 76 is provided outside the sealing region 74, so that the liquid in the liquid tank 31 can be more reliably prevented from passing through the accommodating portion. 76 leaks to the side of the battery unit 12. Moreover, since the cover 70 shown in FIG. 17 has the connector member 79 disposed in the accommodating portion 76, the heater 50 can be easily assembled to the cartridge 20 in a state of being electrically connected to the battery portion 12. again Since the shape of the cover 70 shown in FIG. 17 is a substantially semicircular plate-shaped body, when the cover 70 is assembled to the cartridge 20, the inside formed by the mask member 60 and the outer casing 30 can be enlarged. The area of the air flow path in which the space 62 communicates with the space on the side of the battery unit 12. Therefore, for example, the air inflow port is provided on the upstream side (the battery unit 12 side) closer to the cover 70, so that air can be supplied from the upstream side of the cover 70 to the internal space 62. In this case, the air inflow port 61 may not be provided in the mask member 60. Further, the cover 70 shown in Fig. 17 does not have the projections 75 of the cover 70 shown in Figs. 2 to 16, but the projections 74 may be provided with the projections 75. The accommodating portion 76 has a shape that penetrates the hole between the cover side surface 73 and the second surface 72. However, the accommodating portion 76 may be replaced by a recess having a cover side surface 73 and a second surface 72.

Figure 20 is a perspective view showing another form of the cover 70. Figure 21 is a side cross-sectional view of the cover of Figure 20. As shown in Fig. 20, in the cover 70, like the cover 70 shown in Figs. 17 to 19, the first surface 71 has a sealing region 74, and the shapes of the first surface 71 and the second surface 72 are formed as It is roughly semi-circular.

Moreover, since the cover 70 shown in FIG. 20 has the connector member 79 disposed in the accommodating portion 76, the heater 50 can be easily assembled to the cartridge 20 in a state of being electrically connected to the battery portion 12. Furthermore, since the shape of the cover 70 shown in FIG. 20 is a substantially semi-circular plate-like body, when the cover 70 is assembled to the cartridge 20, the cover member 60 and the outer casing 30 can be enlarged. The area of the air flow path in which the internal space 62 communicates with the space on the side of the battery unit 12. Therefore, for example, the air inflow port is provided on the upstream side (the battery unit 12 side) closer to the cover 70, so that air can be supplied from the upstream side of the cover 70 to the internal space 62. The mask member may also have no air Inflow. Further, the cover 70 shown in Fig. 20 does not have the projections 75 of the cover 70 shown in Figs. 2 to 16, but the projections 74 may be provided with the projections 75. The accommodating portion 76 has a shape that penetrates the hole between the cover side surface 73 and the first surface 71. However, the accommodating portion 76 may be replaced by a recess having a cover side surface 73 and a first surface 71.

Although the examples of the cover 70 of various forms have been described above, in the cover 70 shown in Figs. 17 to 21, the connector member 79 is an arbitrary member. Therefore, when the cover 70 shown in FIGS. 17 to 21 does not have the connector member 79, the lead of the heater 50 is directly connected to the terminal of the battery portion 12 or the lead of the battery portion 12.
