Description

Technical Field

[0001] The present invention relates to a non-combustion heating device, and more specifically, to an aerosol generator.

Background Art

[0002] Generally, an aerosol generator in the related art includes a power supply module and a housing module. The power supply module includes a casing and a battery installed in the casing. Further, the housing module is used to accommodate an aerosol-forming substrate. Usually, an air flow path communicating with the housing module is provided in the casing. When a user inhales aerosol, external gas is conveyed to the housing module through the air flow path and then can be conveyed into the user's mouth.

[0003] In the aerosol generator of the related art, the distance between the container for accommodating the aerosol-forming substrate in the housing module and the upper cover is close. Therefore, when the aerosol-forming substrate is heated, heat is easily transmitted to the upper cover, and the temperature of the upper cover becomes high. Generally, since the upper cover is a part that the user holds by hand, when the temperature of the upper cover becomes high, it gives the user an uncomfortable feeling.

Advantages of the Invention

[0034] The aerosol generator of the present invention has the following beneficial effects. Specifically, the aerosol generator has an airflow path that communicates with the opening, extends at least a portion of the airflow path in the thickness direction of the side wall, extends along the side wall to the side of the support wall facing the aerosol-forming substrate, and then extends toward the opening. This makes it possible to allow external gas to enter the insertion path of the containment and to transport out the aerosol generated by the aerosol-forming substrate. Furthermore, because the aerosol generator has an air barrier between the upper cover and the aerosol-forming substrate due to the airflow path, the situation in which heat is directly transferred to the upper cover and the temperature of the upper cover becomes too high is avoided.

[0037] To ensure a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0038] Figures 1 and 2 show a first embodiment of the aerosol generator according to the present invention. The aerosol generator is capable of heating the aerosol-forming substrate by a low-temperature, non-combustion heating method. In some embodiments, the aerosol-forming substrate may be cylindrical. Specifically, the aerosol-forming substrate is a thread-like or chip-like fixing material consisting of plant leaves and / or stems. Aromatic components may be further added to the fixing material. In some embodiments, the aerosol-forming substrate can be inserted into the aerosol generator. The aerosol generator has the advantages of a simple structure, excellent comfort during use, and a high user experience.

[0039] As shown in Figures 1 to 3, in this embodiment, the aerosol generator includes a containment module 10 and a heating module 20. The containment module 10 is used to contain an aerosol-forming substrate. The heating module 20 is provided within the containment module 10 and is used to generate an aerosol by heating the aerosol-forming substrate for inhalation by the user.

[0040] Furthermore, in this embodiment, the housing module 10 includes a lower base 11, a housing 12, and an upper cover 13. The lower base 11 is used to mount the housing 12 and the heating module 20. The housing 12 is removably assembled to the lower base 11 and is used to house an aerosol-forming substrate. The upper cover 13 covers the outer periphery of the lower base 11 and the housing 12 and is used for user gripping.

[0041] As shown in Figures 4 to 6, in this embodiment, the lower base 11 includes an outer cover 111 and an inner cylinder 112. The outer cover 111 covers the outer circumference of the heating base 21 of the heating module 20 and can be assembled to the power supply module 60. The outer cover 111 has a hollow structure and can form a housing chamber 114 on the inside for housing the heating base 21 and the circuit board 40. The cross-section of the outer cover 111 may be substantially rectangular. The inner cylinder 112 can be installed inside the outer cover 111 and its radial size may be smaller than the length and width of the outer cover 111. The inner cylinder 112 has a hollow structure with both ends passing through and can form assembly holes on the inside. These assembly holes are used to insert a part of the housing 12 and can also allow the heating element 22 of the heating module 20 to pass through.

[0042] In this embodiment, the container 12 includes a housing section 121 and a position regulating section 122. The housing section 121 may be substantially cylindrical and includes a first end 121a and a second end 121b. The first end 121a and the second end 121b are positioned opposite each other. The housing section 121 is inserted into the inner cylinder 112. That is, the lower base 11 can cover the housing section 121. The housing section 121 is used to insert an aerosol-forming substrate. The position regulating section 122 is provided at the first end 121a of the housing section 121. When the housing section 121 is inserted into the inner cylinder 112, the position regulating section 122 is located at one end of the outer cover 111 and can be fitted onto the outer cover 111, thereby regulating the position of the housing section 121.

[0043] As shown in Figure 7, in this embodiment, the housing 121 further includes a support wall 1211, a side wall 1212, and an opening 1213. The support wall 1211 is provided at the second end 121b and is used to support the aerosol-forming substrate. The opening 1213 is provided at the first end 121a and is provided corresponding to the support wall 1211 and is used to insert the aerosol-forming substrate into the housing 121. The side wall 1212 is installable on the support wall 1211 and extends upward in a direction perpendicular to the support wall 1211, or extends so as to gradually widen toward a position close to the opening 1213. The side wall 1212 is connected to the support wall 1211 and, together with the support wall 1211, surrounds and forms an insertion path 1214 for inserting the aerosol-forming substrate. In some embodiments, the size of the cross-section of the insertion path 1214 may be larger than the size of the cross-section of the aerosol-forming substrate, and a gap may be maintained between the insertion path 1214 and the aerosol-forming substrate to facilitate gas flow. Naturally, as can be understood, in some other embodiments, the size of the cross-section of the insertion path 1214 may be the same as the size of the cross-section of the aerosol-forming substrate. Also, in some embodiments, the opening 1213 may be substantially circular. The shape and size of the cross-section of the opening 1213 may be adapted to the shape and size of the cross-section of the aerosol-forming substrate.

[0044] Furthermore, in this embodiment, the support wall 1211 is provided with a through hole 1215. The through hole 1215 is used for inserting the heating element 22. The through hole 1215 may be provided so as to penetrate along the thickness direction of the support wall 1211, and may also be provided so as to face the opening 1213. In some embodiments, the support wall 1211 is provided with a first groove 1216. There may be multiple first grooves 1216. The multiple first grooves 1216 may be provided at intervals in the circumferential direction of the through hole 1215. In some embodiments, the first groove 1216 may be a linear groove, and may extend from the through hole 1215 to the side surface of the support wall 1211. In some embodiments, a second groove 1219 may be provided on the inside of the hole wall of the through hole 1215. There may be multiple second grooves 1219. The plurality of second grooves 1219 may be provided at intervals in the circumferential direction of the through hole 1215. By providing the second grooves 1219, a gap can be maintained between the heating element 22 and the wall of the through hole 1215, making it easier for gas to pass through the second grooves 1219. In some other embodiments, the first groove 1216 may be omitted. In some other embodiments, the second grooves 1219 can also be omitted. In this case, by making the diameter of the through hole 1215 larger than the radial size of the heating element 22, it is possible to facilitate the insertion of the heating element 22 and to maintain a gap between the heating element 22 and the wall of the through hole 1215.

[0045] In this embodiment, an air guide groove 1217 may be provided in the side wall 1212. The air guide groove 1217 may be located in a section of the side wall 1212 adjacent to the opening 1213, and is located on the inner wall surface of the side wall 1212 and communicates with the opening 1213. The air guide groove 1217 is a linear groove and extends for a predetermined length in the direction of the support wall 1211. Specifically, in some embodiments, the extension length of the air guide groove 1217 may be equal to the thickness of the position regulating section 122. Also, the depth of the air guide groove 1217 may be less than the thickness of the side wall 1212. In some embodiments, there are multiple air guide grooves 1217. These multiple air guide grooves 1217 may be provided at intervals in the circumferential direction of the opening 1213 and are used to allow external gas to enter the insertion path 1214.

[0046] In this embodiment, an air supply groove 1218 is provided in the side wall 1212. The air supply groove 1218 may extend in the thickness direction of the side wall 1212. Furthermore, the air supply groove 1218 may be provided in a vertically elongated shape. The air supply groove 1218 extends in the direction of the support wall 1211 along the insertion direction of the aerosol-forming substrate. In some embodiments, one end of the air supply groove 1218 may extend to the support wall 1211. Also, one end may communicate with the air guide groove 1217, and the other end may communicate with the first recessed groove 1216. In some embodiments, the extension length of the air supply groove 1218 in the insertion direction of the aerosol-forming substrate may be half or more of the height of the side wall 1212. Also, the air supply groove 1218 may be provided in a one-to-one ratio with the first recessed groove 1216. In some embodiments, the depth of the air supply groove 1218 may be greater than the thickness of the side wall 1212. Specifically, the air supply groove 1218 may be a through groove and may be provided to penetrate along the thickness direction of the side wall 1212. Naturally, as can be understood, in some embodiments, the air supply groove 1218 is not limited to a through groove and may have a depth less than the thickness of the side wall 1212. After the external gas passes through the guide groove 1217 and enters the air supply groove 1218, it becomes possible to enter the bottom of the aerosol-forming substrate from the first recess 1216. Then, it sends the aerosol generated by the aerosol-forming substrate toward the opening 1213.

[0047] In some embodiments, the position restricting portion 122 is provided to cover the outer circumference of the opening 1213 of the housing portion 121. The length and width of the position restricting portion 122 may both be larger than the radial size of the opening 1213. The position restricting portion 122 is located at one end of the outer cover 111 and is fitted into the outer cover 111 to restrict its position, and may also be connected to and fixed to the upper cover 13 by providing a connecting module.

[0048] Furthermore, as shown in Figures 3 and 4, in this embodiment, the upper cover 13 may cover the lower base 11 and also cover the outer circumference of the container 12. The upper cover 13 is provided with a through hole 131. The through hole 131 may be located in the ceiling wall of the upper cover 13 and provided to correspond to the opening 1213. In some embodiments, the size of the through hole 131 may be larger than the size of the opening 1213 and also larger than the cross-sectional size of the aerosol-forming substrate. This makes it easier for external gas to pass through the through hole 131 and enter the opening 1213. It also makes it easier to load the aerosol-forming substrate into the container 12 and to remove it from the container 12.

[0049] In this embodiment, the heating module 20 includes a heating base 21 and a heating element 22. The heating base 21 is provided at one end of the inner cylinder 112 that is spaced apart from the through hole 131, and may also be located in the lower part of the housing chamber 114 and facing the inner cylinder 112. In some embodiments, the heating base 21 is provided on the side of the support wall 1211 opposite to the aerosol-forming substrate and is spaced apart from the support wall 1211. The heating element 22 may be columnar, insertable into the heating base 21, and positioned perpendicular to the heating base 21. The heating element 22 can enter and be inserted into the aerosol-forming substrate through the through hole 1215, and heats the aerosol-forming substrate by generating heat. Naturally, as can be understood, in some other embodiments, the heating element 22 may be sheet-shaped and is not limited to a columnar shape.

[0050] In addition, in this embodiment, the aerosol generator further includes an airflow path 30. The airflow path 30 communicates with the opening 1213. The airflow path 30 is provided on the side of the containment section 121 facing the aerosol-forming substrate and on the side opposite to the aerosol-forming substrate. Specifically, in this embodiment, the airflow path 30 extends from the opening 1213 toward the support wall 121 and enters the insertion path 1214. Alternatively, a portion of the airflow path may extend in the thickness direction of the side wall 1212, then along the side wall 1212 to the side of the support wall 1211 facing the aerosol-forming substrate, and then extend toward the opening 1213. Naturally, as can be understood, in some other embodiments, the extension is not limited to the side of the support wall 1211 facing the aerosol-forming substrate. In some other embodiments, the airflow path 30 may extend to the side of the support wall 1211 opposite to the aerosol-forming substrate, enter the insertion path 1214 from the support wall 1211, and then extend toward the opening 1213. By providing the airflow path 30 in the housing module 10 to cool the upper cover 13 and lower base 11, the situation in which the temperature of the upper cover 13 and lower base 11 becomes too high and causes discomfort to the user is avoided. The path of the airflow path 30 can also be shortened.

[0051] In this embodiment, the airflow path 30 includes a first air supply path 31, a second air supply path 32, and a third air supply path 33. The first air supply path 31 is formed within the insertion path 1214 and is provided in close proximity to the opening 1213. Specifically, in some embodiments, the first air supply path 31 may be formed in the air guide groove 1217, specifically, in the gap between the air guide groove 1217 and the aerosol-forming substrate. The first air supply path 31 communicates with the opening 1213, thereby enabling communication with the outside. The second air supply path 32 is formed in the side wall 1212 and may extend along the side wall 1212 toward the support wall 1211 and to the inside of the support wall 1211. Specifically, the second air supply path 32 may be a recessed airflow path. Furthermore, the second air supply path 32 may be provided in a bent shape. In some embodiments, the second air supply path 32 is formed in part in the air supply groove 1218 and in part in the first recess 1216. The second air supply path 32 is provided bent relative to the first air supply path 31 and communicates with the first air supply path 31. Naturally, as can be understood, in some other embodiments, the second air supply path 32 is not limited to being formed in the first recess 1216. In some other embodiments, part of the second air supply path 32 may be formed by the gap between the heating base 21 and the support wall 1211, or by the space between a plurality of spaced protrusions on the support wall 1211. In some embodiments, the third air supply path 33 communicates with the second air supply path 32 and extends toward the opening 1213. Specifically, in this embodiment, the third air supply path 33 is provided perpendicular to the support wall 1211, and at least a portion of it is located in the gap between the aerosol-forming substrate and the support wall 1211. The third air supply path 33 can be used to allow gas to enter the aerosol-forming substrate from the bottom of the aerosol-forming substrate. As can be understood, in some other embodiments, the third air supply path 33 may be provided in part along the axial direction of the through-hole 1215, with a portion of it formed in the through-hole 1215.The external gas enters the aerosol-forming substrate by passing through the first air supply path 31, the second air supply path 32, and the third air supply path 33 in sequence, and then carries out the aerosol formed by the heating of the aerosol-forming substrate.

[0052] In this embodiment, the aerosol generator further includes a circuit board 40. The circuit board 40 is provided in the housing chamber 114, connected to the heating base 21, and connectable to the power supply module 60.

[0053] In this embodiment, the aerosol generator further includes a slide cover module 50. The slide cover module 50 includes a slide cover 51 and a slider 52. The slide cover 51 is slidably mounted on the upper cover 13 and can open and close the through hole 131 by sliding. The slider 52 is mounted on the position regulating portion 122 and is located on the side of the upper cover 13 facing the aerosol-forming substrate and is connected to the slide cover 51. As a result, the slide cover 51 is configured to slide.

[0054] In this embodiment, the aerosol generator further includes a power supply module 60. The power supply module 60 includes a casing 61 and a battery 62 housed within the casing 61. The casing 61 is mountable to the lower base 11, and a portion of the lower base 11 is inserted into it. The battery 62 is connected to the circuit board 40 and used to supply electricity to the heat generation module 20.

[0055] Figure 8 shows a second embodiment of the aerosol generator according to the present invention, which differs from the first embodiment in the following respects. Specifically, the airflow path 30 extends in the thickness direction of the side wall 1212, and then extends along the side wall 1212 to the side opposite to the aerosol-forming substrate in the support wall 1211. In other words, it extends to the space between the support wall 1211 and the heating base 21, and then enters the insertion path 1214 from the through hole 1215 and extends toward the opening 1213. This allows external gas to enter the container 12 and carries out the aerosol generated by the aerosol-forming substrate. Furthermore, a portion of the third air supply path 33 of the airflow path 30 may be formed in the through hole 1215.

[0056] To ensure that this is understood, the above embodiments merely represent preferred embodiments of the present invention and, although described in a relatively specific and detailed manner, should not be interpreted as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical characteristics and make some modifications and improvements, provided they do not depart from the concept of the present invention, and all of these fall within the scope of the protection of the present invention. Therefore, equivalent modifications and additions made within the scope of the claims of the present invention shall all fall within the scope covered by the claims of the present invention.
