Aerosol generating devices with electrically operated heaters require batteries and drive circuits, making the devices relatively large. Therefore, when using such an aerosol generator, it is necessary to hold it with at least one hand.

Note that there is also known a non-combustion flavor inhaler that heats a flavor source held by a holding member with a heat source that includes a heat storage material (see Patent Document 2).

One of the objects of the present invention is to achieve further miniaturization or weight reduction in an aerosol generation device.

According to the first aspect, the holder can hold a stick-shaped consumable material, and the smokable substance can be heated by the heated latent heat storage material. Therefore, since the holder does not require a battery and a drive circuit, the holder that functions as an aerosol generator can be made smaller and lighter than a conventional device having an electrically operated heater.

The gist of the second aspect is that in the first aspect, the latent heat storage material is encapsulated in a capsule.

According to the second aspect, even if the latent heat storage material is heated to the melting point (operating point) and melted by the heating section of the charger, it is suppressed from flowing out from the holder. In other words, even if the latent heat storage material melts, the latent heat storage material can be handled as a solid, so the user can safely handle the holder.

In a third aspect, in the first aspect or the second aspect, the latent heat storage material of the holder includes a first latent heat storage material disposed so as to surround the smokable substance of the consumable material inserted from the insertion hole. The gist is to include.

Further, since this prevents the outer surface of the charger from becoming high temperature, the user can hold the charger even when the heating section of the charger is heating the latent heat storage material of the holder.

The gist of a sixth aspect is that in any one of the first to fifth aspects, the holder has a second heat insulating part surrounding the latent heat storage material.

According to the sixth aspect, even if the latent heat storage material is heated to the operating point by the heating section, the heat of the latent heat storage material is suppressed from being transmitted to the outside of the holder. This prevents the outer surface of the holder from becoming hot, allowing the user to grip the holder when using the holder.

In a seventh aspect, in any one of the first to sixth aspects, one of the holder and the charger has a magnet, and the other of the holder and the charger has a magnetic body attracted to the magnet. However, when the charger and the holder are connected, the magnet exerts a magnetic force on the magnetic body so as to maintain the connection with the holder.

According to the seventh aspect, when the charger and the holder are connected, the connection is maintained by the magnet and the magnetic body. Therefore, the influence of the heat of the heating section or the latent heat storage material on the connection structure between the charger and the holder is suppressed.

The gist of an eighth aspect is that in any one of the first to seventh aspects, the heating section is configured to heat the latent heat storage material at a temperature equal to or higher than the operating point of the latent heat storage material. do.

According to the eighth aspect, the latent heat storage material is heated above the operating point and melts. This ensures that when the holder is removed from the charger for use, the latent heat storage material undergoes a phase transition from liquid to solid while maintaining the temperature (melting point) at the operating point, heating the smokable material to the desired temperature. can.

The gist of a ninth aspect is that in any of the first to eighth aspects, the charger includes a temperature sensor configured to measure the temperature of the latent heat storage material.

According to the ninth aspect, the temperature sensor can detect whether the temperature of the latent heat storage material has reached the operating point or higher. Thereby, it is possible to detect that sufficient heat has been stored in the latent heat storage material, and when the holder is used, the smokable substance can be heated to a desired temperature.

In a tenth aspect, in the ninth aspect, the charger includes a control unit that can communicate with the temperature sensor and the heating unit, and the control unit receives data indicating the measured temperature from the temperature sensor, and The gist is that the operation of the heating section is stopped when the measured temperature reaches the operating point or higher of the latent heat storage material.

When using the holder, the smokable substance can be heated to a desired temperature. It can be heated to.

The gist of an eleventh aspect is that in the tenth aspect, the control section stops the operation of the heating section when a predetermined time has elapsed after the measured temperature reaches the operating point of the latent heat storage material. do.

According to the eleventh aspect, the control unit can control the operation of the heating unit to reliably heat the latent heat storage material above the operating point. This ensures that the smokable substance is heated to the desired temperature when the holder is used.

The gist of a twelfth aspect is that in any of the first to eleventh aspects, the holder has a plurality of the latent heat storage materials having different operating points.

According to the twelfth aspect, the smokable material can be partially heated at different temperatures, or the smokable material can be heated at different temperatures over time. Therefore, the heating of the smokable substance can be controlled by a plurality of latent heat storage materials with different operating points.

The gist of a thirteenth aspect is that in the twelfth aspect, the plurality of latent heat storage materials are stacked on each other in a direction perpendicular to the insertion direction of the consumable material.

According to the thirteenth aspect, a plurality of latent heat storage materials having different operating points are stacked in a direction perpendicular to the insertion direction of the consumable material. Therefore, initially, the plurality of latent heat storage materials are maintained at the highest operating point by the latent heat storage material having the highest operating point among the plurality of laminated latent heat storage materials, and then the latent heat storage materials having the next highest operating point The heat storage material maintains the plurality of latent heat storage materials at their operating points. This allows the smokable material to be heated initially to a higher operating point and, over time, to a lower operating point.

A fourteenth aspect is a thirteenth aspect that cites the third aspect, wherein the holder has a plurality of the first latent heat storage materials having different operating points, and the plurality of first latent heat storage materials are used for the consumables. The gist is that the operating point of the first latent heat storage material that is stacked on top of each other in the direction orthogonal to the insertion direction and that is placed on the inside is higher than the operating point of the first latent heat storage material that is placed on the outside. .

According to the fourteenth aspect, a plurality of first latent heat storage materials having different operating points are stacked in a direction perpendicular to the insertion direction of the consumable material. Therefore, initially, a plurality of latent heat storage materials are maintained at a high operating point by a latent heat storage material with a high operating point located on the inside, and then a plurality of latent heat storage materials with a low operating point located on the outside are maintained at a high operating point. The latent heat storage material is maintained at a low operating point. As a result, the smokable substance is initially heated at a high operating point while suppressing the temperature of the latent heat storage material disposed inside near the consumable material from falling below the target heating temperature in the initial heating stage. Over time, the smokable material can be heated at a lower operating point. Moreover, by arranging the latent heat storage material having a low operating point on the outside, energy loss to the outside of the housing can be suppressed.

The gist of the fifteenth aspect is that in the twelfth aspect, the plurality of latent heat storage materials are arranged in line in the insertion direction of the consumable material.

According to a fifteenth aspect, the smokable material can be heated at different temperatures in the direction of insertion of the consumable.

In a 16th aspect, in the 15th aspect, the operating point of the latent heat storage material disposed on the front end side in the insertion direction of the consumable material is the operating point of the latent heat storage material disposed on the rear end side in the insertion direction of the consumable material. The gist is that it is lower than the operating point of.

According to the sixteenth aspect, the leading end of the smokable material is heated at a lower operating point, and the trailing end is heated at a higher operating point. Thereby, it is possible to prevent the generated aerosol from leaking from the front end side of the consumable material and to prevent the aerosol from condensing at the rear end side of the consumable material, and it is possible to efficiently generate the aerosol.

According to a seventeenth aspect, an aerosol generation device is provided. The aerosol generating device includes a housing having an insertion hole into which a consumable material can be inserted, and a latent heat storage material housed in the housing and configured to heat a smokable substance contained in the consumable material.

According to the seventeenth aspect, the aerosol generator can hold the stick-shaped consumable material, and the smokable material can be heated by the latent heat storage material.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals and redundant explanation will be omitted.

FIG. 1 is a schematic side sectional view of the aerosol generation system according to the present embodiment. FIG. 2 is a schematic side sectional view of a charger that constitutes the aerosol generation system according to this embodiment. FIG. 3 is a schematic side sectional view of a holder that constitutes the aerosol generation system according to this embodiment. As shown in FIGS. 1 to 3, an aerosol generation system 100 according to this embodiment includes a charger 10 and a holder 40. Also shown in FIG. 3 is a consumable 110 that is heated in the holder 40. As shown in FIG. 3, the consumable material 110 includes a smokable substance 116 that is heated in the holder 40, a paper tube section 114, and a filter section 112. The consumable product 110 may further include a center hole filter. A center hole filter may be located between the smokable material 116 and the paper tube section 114. The paper tube section 114 can function as a cooling section that cools the aerosol generated by the smokable substance 116. The inside of the paper tube section 114 may be filled with a material such as a sheet for increasing the contact area with the aerosol and promoting cooling of the aerosol.

The holder 40 is configured to heat the solid or liquid smokable material 116 to atomize the smokable material 116. The smokable substance 116 constitutes a part of the consumable material 110, which has a columnar shape, for example, extending along the longitudinal direction. The consumable material 110 may be, for example, a tobacco stick in which the smokable material 116 includes tobacco. The smokable material 116 included in the consumable 110 may contain an aerosol source that is heated to a predetermined temperature to generate an aerosol. The type of aerosol source is not particularly limited, and extracts from various natural products and/or their constituent components can be selected depending on the purpose. Aerosol sources can include, for example, glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. The smokable material 116 may be tobacco, such as lamina, ribs, or other known plants. Further, the shape of the smokable substance 116 such as tobacco may be shredded, sheet-like, string-like, powder-like, granular, pellet-like, slurry-like, or porous.

As shown in FIGS. 1 and 3, the holder 40 (corresponding to an example of an aerosol generator) has a latent heat storage material 50 (corresponding to an example of a first latent heat storage material). It is preferable that the holder 40 has a side wall 43 (corresponding to an example of a second heat insulating part) surrounding the latent heat storage material 50. Thereby, even if the latent heat storage material 50 is heated to the operating point by the heating section 12 of the charger 10, which will be described later, the heat of the latent heat storage material 50 is suppressed from being transferred to the outside of the holder 40. As a result, the outer surface of the holder 40 is prevented from becoming hot, so the user can grip the holder 40 when using the holder 40. Specifically, in this embodiment, the holder 40 includes a cylindrical side wall 43 as a part of the housing 41. However, the present invention is not limited to this, and the holder 40 may have a heat insulating section surrounding the latent heat storage material 50, in addition to the side wall 43 that is a part of the housing 41.

The housing 41 has an insertion hole 41a into which the consumable material 110 can be inserted. In this embodiment, the housing 41 further includes an end wall 42 provided at one end of a side wall 43, and the insertion hole 41a is formed in the end wall 42. The present invention is not limited to this, and the housing 41 may not include the end wall 42 as long as it can hold the latent heat storage material 50. Further, the housing 41 may include another end wall at the other end of the side wall 43. In this case, this other end wall may be provided with a hole into which the heating part 12 of the consumable material 110 or the charger 10, which will be described later, can be inserted.

The latent heat storage material 50 is housed within the housing 41 and is configured to heat the smokable substance 116 contained in the consumable material 110 inserted into the holder 40 as shown in FIG. In the example shown in FIGS. 1 and 3, the latent heat storage material 50 may be arranged to surround the smokable substance 116 of the consumable material 110 inserted through the insertion hole 41a. This allows the latent heat storage material 50 to heat the smokable substance 116 from the outside. Specifically, in the example shown in FIGS. 1 and 3, the latent heat storage material 50 has a cylindrical shape with a hole 50a into which a consumable material 110 or a heating section 12 described below can be inserted. As shown in FIG. 3, the latent heat storage material 50 is configured to come into contact with the outer peripheral surface of the consumable material 110 when the consumable material 110 is inserted into the holder 40. Thereby, the consumable material 110 can be held in the holder 40.

The latent heat storage material 50 generates heat due to latent heat (also referred to as heat of fusion or heat of crystallization). Specifically, when the latent heat storage material 50 is heated, it undergoes a phase transition from solid to liquid, and can store heat from the heating source. Thereafter, the latent heat storage material 50 can maintain a predetermined temperature (operating point or melting point) while undergoing a phase transition from a liquid to a solid, supply the accumulated thermal energy to the smokable material 116, and become a smokable material that has received the thermal energy. The substance 116 efficiently generates an aerosol or the like.

The latent heat storage material 50 is preferably composed of one or more alloys selected from Mg-Zn, Zn-AL, and Al-Si, and is, for example, a Mg-Zn-Ni alloy. Further, the operating point (melting point) of the latent heat storage material 50 is preferably 250°C or more and 400°C or less, and specifically may be about 300°C, for example. In addition, the metal-based latent heat storage material 50 not only has high heat resistance but also high thermal conductivity, so the temperature inside thereof tends to be uniform, so that heat can be efficiently stored and radiated.

It is preferable that the latent heat storage material 50 is enclosed in a capsule. Thereby, even if the latent heat storage material 50 is heated to a melting point (operating point) and melted by the heating section 12 of the charger 10, which will be described later, it is suppressed from flowing out from the holder 40. In other words, even if the latent heat storage material 50 melts, the latent heat storage material 50 can be handled as a solid, so the user can safely handle the holder 40. The capsule in which the latent heat storage material 50 is enclosed may be a microcapsule. Additionally, the microcapsules may be constructed from a ceramic material such as alumina. The plurality of capsules in which the latent heat storage material 50 is enclosed may be fixed inside the holder 40 using, for example, a heat-resistant adhesive or binder. As the binder, an inorganic binder with high heat resistance can be suitably used. Specifically, for example, an inorganic binder containing alumina can be used.

The latent heat storage material 50 may be mixed with a retention material. The latent heat storage material 50 mixed with the holding material can be fixed inside the holder 40 using, for example, a heat-resistant adhesive or the like. Specifically, the holding material is preferably a material that can hold the latent heat storage material 50 even when the latent heat storage material 50 reaches its melting point and melts. More specifically, the holding material that holds the latent heat storage material 50 is preferably a compound having a multilayer structure, and vermiculite is particularly preferable as the compound having a multilayer structure. By using vermiculite as the holding material, excessive heat radiation per unit time to the outside of the latent heat storage material 50 is suppressed, and the heat is gradually released. As a result, a temperature that volatilizes a sufficient amount of aerosol can be maintained over a certain period of time.

Furthermore, when vermiculite is used as the holding material, the content of the holding material is preferably 100% by weight or more and 200% by weight or less based on the latent heat storage material 50. By setting the weight percentage of vermiculite to the latent heat storage material 50 to be 100% or more, the holding material can hold a sufficient amount of the latent heat storage material 50. Therefore, even when the latent heat storage material 50 is heated and melted, the outflow of the latent heat storage material 50 from the holder 40 can be suppressed. By setting the weight percentage of vermiculite to the latent heat storage material 50 to be 200% or less, it is possible to suppress excessive loss of the amount of heat released by the latent heat storage material 50 when melted to the vermiculite.

As shown in FIGS. 1 and 2, the charger 10 is configured to be connectable to the holder 40. The charger 10 also includes a heating section 12 configured to heat the latent heat storage material 50 of the holder 40. In this embodiment, the heating unit 12 is a pin-shaped heating unit 12 that is inserted into the hole 50a of the latent heat storage material 50 and heats the latent heat storage material 50 from inside. The heating unit 12 may be, for example, a resistance heating type heater. The heating unit 12 is not limited to this, and may be an induction heating type heater. In that case, the charger 10 may have a coil (not shown) that heats the heating section 12 by induction.

According to the aerosol generation system 100 shown in FIGS. 1 to 3, the holder 40 can hold the stick-shaped consumable material 110, and the smokable material 116 is heated by the latent heat storage material 50 heated by the heating section 12. be able to. Therefore, since the holder 40 does not require a battery or a drive circuit, the holder 40 functioning as an aerosol generator can be made smaller or lighter in weight than a conventional device having an electrically operated heater.

It is preferable that the charger 10 has a heat insulating part 10a surrounding the heating part 12. In this case, when the heating section 12 of the charger 10 is heating the latent heat storage material 50 of the holder 40, the heat of the heating section 12 is suppressed from being transmitted to the outside of the charger 10. It can be heated efficiently. Further, since the outer surface of the charger 10 is prevented from becoming high temperature, the user can hold the charger 10 even when the heating section 12 of the charger 10 is heating the latent heat storage material 50 of the holder 40. In this embodiment, the side wall portion of the housing of the charger 10 functions as the heat insulating part 10a, but the present invention is not limited to this, and the charger 10 may have a heat insulating part separate from the housing.

One of the holder 40 and the charger 10 has a magnet, and the other of the holder 40 and the charger 10 has a magnetic material that is attracted to the magnet, and when the charger 10 and the holder 40 are connected as shown in FIG. , it is preferable that the magnet exerts a magnetic force on the magnetic body so as to maintain the connection with the holder 40. In this case, when the charger 10 and the holder 40 are connected, the connection is maintained by the magnet and the magnetic material. This prevents the heat of the heating section 12 or the latent heat storage material 50 from affecting the connection structure between the charger 10 and the holder 40. The magnet can be a permanent magnet or an electromagnet. Further, in this specification, the magnetic material may include a magnet.

In this embodiment, as an example, the charger 10 has a magnet 14, and the holder 40 has a magnetic body 44 that is attracted to the magnet 14. More specifically, as shown in FIGS. 1 to 3, the magnet 14 and the magnetic body 44 are preferably arranged to face each other in the attachment/detachment direction of the holder 40 to/from the charger 10 (vertical direction in FIG. 1). . As a result, the magnet 14 and the magnetic body 44 generate an attractive force that opposes the direction in which the holder 40 is removed from the charger 10, so that the connection between the holder 40 and the charger 10 can be more firmly maintained. Note that the housings of the charger 10 and the holder 40 may function as magnets or magnetic bodies.

The heating unit 12 of the charger 10 is preferably configured to heat the latent heat storage material 50 at a temperature equal to or higher than the operating point of the latent heat storage material 50. In this case, the latent heat storage material 50 is heated above the operating point and melts. As a result, when the holder 40 is removed from the charger 10 for use, the latent heat storage material 50 undergoes a phase transition from liquid to solid while maintaining the temperature (melting point) at the operating point, bringing the smokable substance 116 to the desired temperature. Can be heated.

As shown in FIGS. 1 and 2, the charger 10 preferably includes a temperature sensor 15 configured to measure the temperature of the latent heat storage material 50. In this case, the temperature sensor 15 can detect whether the temperature of the latent heat storage material 50 has reached the operating point or higher. Thereby, it can be detected that sufficient heat has been stored in the latent heat storage material 50, and when the holder 40 is used, the smokable substance 116 can be heated to a desired temperature.

Furthermore, it is preferable that the charger 10 has a control section 16 that can communicate with the temperature sensor 15 and the heating section 12. The control section 16 controls the operation of the heating section 12 . Specifically, the control unit 16 receives data indicating the measured temperature from the temperature sensor 15, and stops the operation of the heating unit 12 when the measured temperature reaches the operating point of the latent heat storage material 50 or higher. In this case, the control unit 16 can control the operation of the heating unit 12 to heat the latent heat storage material 50 to a temperature higher than the operating point. As a result, it is possible to prevent the latent heat storage material 50 from being excessively heated and to determine that heat has been sufficiently stored in the latent heat storage material 50. When using the holder 40, the smokable substance 116 can be It can be heated to the desired temperature. Charger 10 further includes a battery 17. Battery 17 stores electric power used by charger 10 . For example, battery 17 is a lithium ion battery. Battery 17 may be rechargeable by an external power source. The control unit 16 is communicably connected to the battery 17 and is configured to supply power from the battery 17 to the heating unit 12 . Note that the charger 10 may be a stationary device that can be installed in a smoking area or the like. In that case, since power can be supplied directly from the plug, it is not necessary to provide the battery 17 inside the charger 10. Further, the charger 10 may be able to accommodate a plurality of holders 40 at the same time.

Further, it is more preferable that the control unit 16 stops the operation of the heating unit 12 when a predetermined time has elapsed after the temperature measured by the temperature sensor 15 reaches the operating point of the latent heat storage material 50. In this case, the control unit 16 can control the operation of the heating unit 12 to more reliably heat the latent heat storage material 50 above the operating point. This ensures that the smokable substance 116 is heated to the desired temperature when the holder 40 is used.

Next, an aerosol generation system 100 according to another embodiment will be described. FIG. 4 is a schematic side sectional view of an aerosol generation system 100 according to another embodiment. FIG. 5 is a schematic side sectional view of the charger 10 that constitutes the aerosol generation system 100 according to another embodiment. FIG. 6 is a schematic side sectional view of a holder 40 that constitutes an aerosol generation system 100 according to another embodiment. Also shown in FIG. 6 is a consumable 110 that is heated in the holder 40. The aerosol generation system 100 shown in FIGS. 4 to 6 differs from the aerosol generation system 100 shown in FIGS. 1 to 3 in the shapes of the heating section 12 and the latent heat storage material 50.

Specifically, as shown in FIGS. 4 and 6, the latent heat storage material 50 (corresponding to an example of the second latent heat storage material) of the holder 40 is configured to absorb the smokable substance of the consumable material 110 inserted through the insertion hole 41a. 116. This allows the latent heat storage material 50 to heat the smokable substance 116 from the inside. The latent heat storage material 50 can have any shape that can be inserted into the smokable material 116, such as a pin or a blade. In the embodiment shown in FIG. 6, the insertion hole 41a is not provided in the end wall 42, and the opening of the side wall 43 on the side opposite to the end wall 42 functions as the insertion hole 41a. As shown in FIG. 6, the latent heat storage material 50 is inserted into the smokable material 116 of the consumable 110 when the consumable 110 is inserted into the holder 40. Thereby, the consumable material 110 can be held in the holder 40.

Further, as shown in FIGS. 4 and 5, the heating section 12 of the charger 10 has a substantially cylindrical shape with a hole 12a extending along the attachment/detachment direction of the holder 40 to/from the charger 10. As shown in FIG. 4, when the holder 40 is connected to the charger 10, the latent heat storage material 50 of the holder 40 is inserted into the hole 12a of the heating section 12 of the charger 10. Thereby, the heating unit 12 can heat the latent heat storage material 50 from the outside.

Note that the charger 10 shown in FIGS. 4 and 5 may further include the heating section 12 shown in FIGS. 1 to 3. In this case, the holder 40 has the cylindrical latent heat storage material 50, and the heating unit 12 can heat the cylindrical latent heat storage material 50 from inside and outside. Further, the holder 40 shown in FIGS. 4 and 6 may further include the latent heat storage material 50 shown in FIGS. 1 to 3. In this case, the latent heat storage material 50 can heat the smokable substance 116 from the inside and the outside.

Next, a holder 40 according to another embodiment will be described. FIG. 7 is a schematic side sectional view of a holder 40 according to another embodiment. FIG. 8 is a schematic side sectional view of a holder 40 according to yet another embodiment. The holder 40 shown in FIGS. 7 and 8 includes a plurality of latent heat storage materials having different operating points. In this case, the smokable material 116 may be heated at different temperatures in sections or the smokable material 116 may be heated at different temperatures over time. Therefore, the heating of the smokable material 116 can be controlled by a plurality of latent heat storage materials having different operating points.

In the holder 40 shown in FIG. 7, a plurality of latent heat storage materials are stacked on each other in a direction perpendicular to the direction in which the consumable material 110 is inserted. Specifically, in the holder 40 shown in FIG. 7, a latent heat storage material 51, a latent heat storage material 52, and a latent heat storage material 53 having different operating points are stacked on each other in a direction perpendicular to the insertion direction of the consumable material 110. It has a hole 50a in the center into which the heating part 12 or the consumable material 110 is inserted.

In the example shown in FIG. 7, the operating point of the latent heat storage material 51 placed on the inside is preferably higher than the operating point of the latent heat storage material 52 or 53 placed on the outside. Specifically, in the example shown in FIG. 7, the operating point of the latent heat storage material 51 is the highest, and may be, for example, about 350°C. Further, the operating point of the latent heat storage material 53 may be the lowest, for example, about 270°C.
