Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] In an aerosol generating device, aerosols can be generated by heating the aerosol generating product.

[0003] To improve ease of use, some aerosol generating devices employ a pusher structure to automatically discharge the generated aerosol product. That is, after the aerosol product has finished heating, the pusher structure pushes it out of the heating chamber to prevent residue buildup or manual cleaning by the user.

[0004] However, during the ejection of the aerosol-generating product by the pusher structure, the filter structure on the pusher comes into contact with and compresses the aerosol-generating product, causing debris from the aerosol-generating product to adhere to or become stuck on the filter structure. Furthermore, the debris may undergo localized carbonization or adhesion under high-temperature conditions, further exacerbating the degree of filter clogging. Utility Model Content

[0005] The purpose of this invention is to provide an aerosol generating device to solve the problem of filter clogging caused by debris adhering to the filter structure.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An aerosol generating apparatus, comprising:

[0008] A heating element, wherein the heating element is provided with a chamber for containing an aerosol-generated product;

[0009] A push rod assembly, wherein the push rod assembly has an internal air passage;

[0010] A filter element is provided on the pusher assembly, and the aerosol generated by the aerosol generating product enters the air passage through the filter element from the chamber.

[0011] The filter element has a first abutting portion for squeezing the aerosol generating article to detach it from the chamber; and / or, the push rod assembly has a first end that is retractable within the chamber, the first end being closer to the aerosol generating article than the filter element, the first end being used to squeeze the aerosol generating article to detach it from the chamber.

[0012] As an alternative to an aerosol generating device, the filter element includes a filter section having a plurality of through holes for the aerosol to pass through.

[0013] As an alternative to an aerosol generating device, a portion of the structure of the filter extends toward the interior of the chamber to form the first abutment portion.

[0014] As an alternative to the aerosol generating apparatus, the first contact portion is formed at a location closer to the aerosol generating article before the first contact portion contacts the aerosol generating article.

[0015] As an alternative to the aerosol generating device, the filter element includes a connecting portion inserted into the air passage, the connecting portion being press-fitted with the inner wall of the air passage.

[0016] As an alternative to the aerosol generating device, the filter element includes a connecting portion that is inserted into the air passage and engages with the inner wall of the air passage.

[0017] As an alternative to the aerosol generating device, a second abutment is provided on the first end, and the second abutment is used to compress the aerosol generated product.

[0018] As an alternative to the aerosol generating device, the first contact part and the filter element are an integral structure.

[0019] As an alternative to the aerosol generating device, the first contact portion is detachably connected to the filter element.

[0020] As an alternative to the aerosol generating device, the pusher assembly also has a second end opposite to the first end, and the second end is provided with a nozzle that communicates with the air passage.

[0021] Beneficial effects:

[0022] In this invention, by directly providing a first abutment portion on the filter element and using the first abutment portion to compress the aerosol-generating product, or by directly using the end of the push rod assembly to compress the aerosol-generating product, the filtration portion of the filter element can be prevented from directly contacting the aerosol-generating product. This avoids the adhesion or jamming of aerosol-generating product debris in the filtration portion of the filter element, thus preventing the filter element from failing to filter. Furthermore, it solves the problem of severe clogging of the filtration portion of the filter element due to the potential for localized carbonization or adhesion of debris under high-temperature conditions.

[0037] Please see the appendix Figure 1 -Appendix Figure 4 This embodiment relates to an aerosol generating device 10. The aerosol generating device 10 includes a heating element 1, a pusher assembly 2, and a filter element 3. The heating element 1 has a chamber 11 for receiving an aerosol-generated product 100; the pusher assembly 2 has an internal air passage 23; the filter element 3 is disposed on the pusher assembly 2, and the aerosol generated by the aerosol-generating product 100 enters the air passage 23 through the chamber 11 and the filter element 3; wherein, the filter element 3 has a first abutment portion 31, which is used to squeeze the aerosol-generating product 100 to disengage it from the chamber 11; and / or, the pusher assembly 2 has a first end 21 that is retractable within the chamber 11, the first end 21 being closer to the aerosol-generating product 100 than the filter element 3, and the first end 21 being used to squeeze the aerosol-generating product 100 to disengage it from the chamber 11.

[0038] It should be noted that this device needs to be used in conjunction with the aerosol generating product 100, so that the aerosol generating product 100 generates aerosols. The aerosol generating product 100 used in this embodiment has a block structure, and the aerosol generating product 100 may have an aerosol generating matrix.

[0039] As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form inhalable aerosols. An aerosol-generating matrix may include tobacco-containing materials containing volatile tobacco flavor compounds that are released from the substrate upon heating. Specifically, the aerosol-generating matrix may be a tobacco-containing aerosol-generating matrix or an aerosol-generating matrix containing solid tobacco. Alternatively, the aerosol-generating matrix may include non-tobacco materials. The aerosol-generating matrix may also include aerosol-forming agents. Examples of suitable aerosol-forming agents are glycerol and propylene glycol.

[0040] In this embodiment, the heating element 1 is an infrared heating tube. A cylindrical chamber 11 is formed inside the heating element 1. The chamber 11 contains and heats the aerosol generating product 100, thereby heating the aerosol generating product 100 and generating aerosol for the user to inhale. The push rod assembly 2 has a first end 21 that is retractable within the chamber 11, and a second end 22 opposite to the first end 21. The second end 22 is located outside the chamber 11 and has a suction nozzle 24 that communicates with the airway 23. The suction nozzle 24 is the direct part of the user's mouth that holds the product. The aerosol generated by the aerosol generating product 100 passes through the filter 3 from the chamber 11 and enters the airway 23, then through the airway 23 and into the user's oral cavity via the suction nozzle 24. The filter element 3 can not only block some impurities from entering the airway 23 from the chamber 11, but also prevent impurities from falling from the airway 23 into the chamber 11, thus avoiding affecting the composition of the aerosol generated by the aerosol product 100 and ensuring a consistent inhalation experience for the user.

[0041] In one embodiment of this invention, a first abutting part 31 is provided on the filter element 3. When the push rod assembly 2 is pushed, the first abutting part 31 can extend into the interior of the chamber 11, thereby pushing the heated aerosol generating product 100 through the first abutting part 31 and separating it from the other side of the chamber 11, thereby achieving the purpose of separating the aerosol generating product 100 from the aerosol generating device 10.

[0042] This method, by directly providing the first abutment portion 31 on the filter element 3, prevents the filtration portion of the filter element 3 from directly contacting the aerosol generating product 100, thereby further preventing debris from the aerosol generating product 100 from adhering to or getting stuck in the filtration portion of the filter element 3, thus causing the filtration function of the filter element 3 to fail. It also further solves the problem of severe clogging of the filtration portion of the filter element 3 due to the possibility of local carbonization or adhesion of debris under high-temperature environments.

[0043] In another embodiment of this invention, the first end 21 of the pusher assembly 2 is closer to the aerosol generating product 100 than the filter element 3. When the pusher assembly 2 is pushed, the first end 21 of the pusher assembly 2 directly squeezes the heated aerosol generating product 100 and separates it from the other side of the chamber 11, thereby achieving the purpose of separating the aerosol generating product 100 from the aerosol generating device 10. Specifically, a second abutment portion (not shown in the figure) protrudes from the first end 21. The second abutment portion can be rod-shaped or ring-shaped, and the second abutment portion is used to squeeze the aerosol generating product 100.

[0044] This method directly contacts the aerosol generating product 100 through the end of the push rod assembly 2, completely avoiding contact between the filter element 3 and the aerosol generating product 100. This further prevents debris from the aerosol generating product 100 from adhering to or getting stuck in the filtration section of the filter element 3, thus preventing the filter element 3 from failing to filter. It also further solves the problem of severe clogging of the filtration section of the filter element 3 due to the possibility of local carbonization or adhesion of debris under high-temperature conditions.

[0045] Optionally, the filter element 3 includes a filter section 32, which has a plurality of through holes 321 for aerosols to pass through.

[0046] In this embodiment, the filter section 32 is in the shape of a circular plate, and a plurality of circular through holes 321 are arrayed on the surface of the filter section 32. The through holes 321 allow aerosol inside the chamber 11 to pass through and enter the air passage 23. At the same time, the filter section 32 can also block some large particulate impurities from passing through and falling into the chamber 11, which will affect the quality of the aerosol.

[0047] Optionally, a portion of the structure of the filter section 32 extends toward the interior of the chamber 11 to form a first contact section 31.

[0048] In this embodiment, a first abutment portion 31 protrudes outward on the side of the filter portion 32 facing the chamber 11. The first abutment portion 31 can be formed by integral molding of the filter portion 32 to reduce costs. Of course, the first abutment portion 31 can also be fixed to the filter portion 32 by a detachable connection method such as threaded connection or snap-fit, ensuring convenient assembly and disassembly. Welding can also be used for fixed connection. Those skilled in the art can specifically select the connection method according to the convenience and economy of assembly.

[0049] Furthermore, before the first contact portion 31 contacts the aerosol generating article 100, the filter portion 32 forms the first contact portion 31 at a location closer to the aerosol generating article 100.

[0050] In this embodiment, the aerosol-generated product 100 has a block structure with a slightly bulging top and bottom, forming a short columnar structure that is thick in the middle and thin at the edges.

[0051] By forming a first contact portion 31 on the part of the filter section 32 near the aerosol generating article 100, it can be ensured that the push rod assembly 2 can contact and squeeze the aerosol generating article 100 with a small displacement, thereby further shortening the stroke of the push rod assembly 2.

[0052] In one implementation of this embodiment, the filter element 3 includes a connecting part 33, which is inserted into the air passage 23 and is interference-fitted with the inner wall of the air passage 23.

[0053] In this embodiment, the connecting part 33 is annular, and one end is connected to the filter part 32. The connecting part 33 and the filter part 32 can be integrally formed, or they can be connected by snap-fit ​​or welding. The outer diameter of the connecting part 33 is slightly larger than the inner diameter of the air passage 23, so that the filter element 3 and the push rod assembly 2 can be assembled by interference fit between the connecting part 33 and the inner wall of the air passage 23. The structure is simple and the connection is stable.

[0054] In another implementation of this embodiment, the connecting part 33 is inserted into the air passage 23 and the connecting part 33 is engaged with the inner wall of the air passage 23.

[0055] Specifically, a buckle can be provided on the inner wall of the airway 23, and a locking hole that cooperates with the buckle can be provided on the connecting part 33. When the filter element 3 is inserted into the airway 23, the buckle is engaged in the locking hole. Multiple buckles and locking holes can be provided circumferentially to ensure the reliability of the engagement, but this embodiment does not limit the specific number.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
