[0003] Currently, aerosol generating devices generally adopt an integrated filter design, which is difficult to disassemble, thus increasing the maintenance cost of the entire aerosol generating device. In addition, existing filters only focus on a single function, making it difficult to meet the diverse needs of customers, resulting in poor practicality and reduced user experience. Utility Model Content

[0004] The purpose of this invention is to provide a filter and an aerosol generating device. The filter can be used independently, while expanding the function of the filter, improving the user experience and the practicality of the product.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A filter comprising:

[0007] The main body has a first airflow chamber and a second airflow chamber that are isolated from each other. The first airflow chamber is used to allow a first aerosol to flow through, and the second airflow chamber is used to allow a second aerosol to flow through. The second airflow chamber is filled with a filter material.

[0012] As an alternative filter, the body is provided with a first air inlet and at least one second air inlet, the first aerosol can enter the first airflow chamber through the first air inlet, and the second aerosol can enter the second airflow chamber through the second air inlet.

[0013] As an alternative filter, the body is provided with an installation chamber for inserting an aerosol-generating article, and the second air inlet is defined within the installation chamber and communicates with the second airflow chamber.

[0014] As an alternative filter, the first air inlet is located on the side wall of the body, and the filter further includes a seal for blocking the first air inlet.

[0015] As an alternative filter, the mounting chamber is located at the end of the body away from the nozzle, and the mounting chamber is eccentrically positioned relative to the central axis of the body.

[0016] As an alternative to the filter, the mounting chamber is provided with a snap or slot.

[0017] As an alternative filter, the body has a first end near the nozzle and a second end away from the nozzle, and a side surface extending between the first end and the second end, the connection surface between the side surface and the end face of the second end having a different curvature.

[0021] The portion of the outer shell of the main body located at the filter material is a transparent structure.

[0022] An aerosol generating apparatus includes a main body, an atomizer, and a filter as described in any of the above embodiments. The atomizer is used to atomize a liquid matrix to generate a first aerosol. The filter is removably connected to the main body and is at least partially housed within the main body. When the filter is connected to the main body, a first airflow chamber communicates with the atomizer to receive the first aerosol, and a second airflow chamber is used to receive a second aerosol produced by an aerosol generating article inserted into the main body.

[0024] Beneficial effects:

[0025] In the first aspect of this invention, the main body is provided with an installation chamber for the smooth insertion of the aerosol generating product. The installation chamber is connected to a second airflow chamber, allowing the second aerosol generated by the heated aerosol generating product to pass through the installation chamber and enter the second airflow chamber. The first airflow chamber allows the first aerosol to pass through. A filter material can filter the second aerosol flowing through the second airflow chamber. The first and second aerosols can be mixed inside the mouthpiece, allowing the user to inhale the mixed aerosols into their mouth. This filter can not only be used by directly inserting the aerosol generating product but also filter the second aerosol generated by the product, thus improving safety.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] Please see the appendix Figure 1 -Appendix Figure 3 The first aspect of this embodiment relates to a filter, which includes a body 1 and a nozzle 2. The body 1 has a first airflow chamber 11 and a second airflow chamber 12 that are isolated from each other. The first airflow chamber 11 is for a first aerosol to flow through, and the second airflow chamber 12 is for a second aerosol to flow through. The second airflow chamber 12 is filled with a filter material 3. The nozzle 2 is connected to or is part of the body 1, and the first aerosol and the second aerosol flowing through the filter material 3 can merge inside the nozzle 2 to form a mixed aerosol.

[0049] It should be noted that this aerosol generating device needs to be used in conjunction with the aerosol generating article 100 to generate aerosols; in some applications, the aerosol generating article 100 can also be used alone, such as when it is ignited and inhaled. The aerosol generating article 100 can be generally a rod-shaped structure extending longitudinally, and the tobacco segment in the aerosol generating article 100 can contain an aerosol generating matrix. As a suitable example of this application, the aerosol generating article 100 can be a conventional cigarette, used in conjunction with the aforementioned aerosol generating device. During use, the filter segment of the conventional cigarette can be inserted into the aerosol generating device from the end opposite to the mouthpiece, and then held by the aerosol generating device, while the tobacco segment is exposed outside the aerosol generating device. The second aerosol generated by igniting the tobacco segment enters the second airflow chamber 12 through the cigarette itself, and further merges with the first aerosol flowing out of the first airflow chamber 11 to form a mixed aerosol.

[0050] 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.

[0051] Specifically, the main body 1 is a cylindrical structure with a cavity, and the first airflow chamber 11 and the second airflow chamber 12 are separated by an internal partition plate. One end of the main body 1 also has an installation chamber 13, the size and shape of which are adapted to the size and shape of the aerosol generating product 100, allowing for easy insertion of the aerosol generating product 100. Simultaneously, the installation chamber 13 communicates with the second airflow chamber 12, allowing the second aerosol generated by the combustion of the aerosol generating product 100 to pass through the installation chamber 13 and enter the second airflow chamber 12, while the first airflow chamber 11 allows the first aerosol to pass through. The filter material 3 can be either activated carbon or a filter cartridge to filter the second aerosol flowing through the second airflow chamber 12. The first and second aerosols can be mixed inside the mouthpiece 2, which is the direct contact part for the user to hold in their mouth. Through the suction holes on the mouthpiece 2, the user can inhale the mixed first and second aerosols into their oral cavity.

[0052] In this embodiment, the filter can not only be directly inserted into the aerosol generating product 100 for use, but also filter the second aerosol generated by the aerosol generating product 100 to improve safety. Furthermore, a first aerosol can be introduced to enhance the user's inhalation experience. For example, the first aerosol is an atomized aerosol with a fragrance. The first aerosol can be customized according to user needs, expanding the filter's functionality and improving the user experience and product practicality.

[0053] In this embodiment, the filter can be used alone or in conjunction with an aerosol generating device, where a first aerosol is generated and mixed inside the filter. This facilitates both the individual carrying and use of the filter and expands the versatility of the aerosol generating device.

[0054] Optionally, the cross-sectional area of ​​the second airflow chamber 12 is larger than the cross-sectional area of ​​the first airflow chamber 11.

[0055] Specifically, the spatial dimensions of the first airflow chamber 11 and the second airflow chamber 12 can be adjusted according to usage requirements. In this embodiment, the first aerosol only provides some aroma to enhance the taste; the main source of inhalation for the user is still the second aerosol generated by the aerosol generating product 100. Therefore, the cross-sectional area of ​​the first airflow chamber 11 is smaller than that of the second airflow chamber 12, so that the mixed aerosol is mainly composed of the second aerosol. At the same time, this further avoids an excessively large overall structural size, making the filter more compact.

[0056] Optionally, the first airflow chamber 11 and the second airflow chamber 12 extend side by side along the longitudinal direction of the filter.

[0057] In this embodiment, the first airflow chamber 11 and the second airflow chamber 12 are arranged side by side along the same direction, which can ensure that the first aerosol and the second aerosol flow in the same direction and enter the nozzle 2 for mixing, thus ensuring sufficient mixing. At the same time, the side-by-side extension of the first airflow chamber 11 and the second airflow chamber 12 can also take into account the compactness of the overall filter structure.

[0058] Please continue to refer to the appendix. Figure 2 and attached Figure 3 Optionally, the inner ring of the body 1 is provided with a stepped portion 131, which is used to abut against the aerosol generating article 100 that can generate the first aerosol. Multiple stepped portions 131 are arranged sequentially along the insertion direction of the aerosol generating article 100 and their inner diameter gradually decreases.

[0059] Specifically, the mounting chamber 13 of the main body 1 is provided with a step 131 inside. The step 131 is used to fix the aerosol generating product 100. When using it, the user only needs to insert the aerosol generating product 100 into the mounting chamber 13 from the bottom and use the step 131 to hold it in place. It is simple and convenient to use.

[0060] In this embodiment, by providing multiple stepped portions 131, which are arranged sequentially along the insertion direction of the aerosol generating product 100 and whose inner diameter gradually decreases, the filter can adapt to a variety of aerosol generating products 100 of different specifications (the outer diameter of aerosol generating products 100 of different specifications is different), thereby improving the adaptability of the filter and ensuring the user's experience.

[0061] Optionally, the main body 1 is provided with a first air inlet 14 and at least one second air inlet 19. The first aerosol can enter the first airflow chamber 11 through the first air inlet 14, and the second aerosol can enter the second airflow chamber 12 through the second air inlet 19.

[0062] Specifically, the first air inlet 14 is located on the side wall of the main body 1 and close to the nozzle 2. When the filter is used alone, i.e., when the user only obtains the second aerosol flowing through the second airflow chamber 12, the first airflow chamber 11 is idle. Therefore, to prevent dust or moisture from entering and affecting the taste and quality of the inhaled second aerosol, the first air inlet 14 is sealed by the sealing member 5 when the filter is used alone. The sealing member 5 can be a sealing plug, which closes the first air inlet 14 through elastic deformation.

[0063] In this embodiment, the second air inlet 19 is confined within the mounting chamber 13 and communicates with the second airflow chamber 12.

[0064] The second air inlet 19 is a circular hole, through which the second aerosol can enter the second airflow chamber 12. By setting multiple second air inlets 19, the air intake rate of the second aerosol can be increased, ensuring that the main component inhaled by the user is the second aerosol.

[0065] Please see the appendix Figure 4 Optionally, the mounting chamber 13 is located at the end of the body 1 away from the nozzle 2, and the mounting chamber 13 is eccentrically positioned relative to the central axis of the body 1.

[0066] When the filter is used alone, the mounting chamber 13 can be used to insert the aerosol generating article 100. Simultaneously, when the user needs to use it in conjunction with an aerosol generating device, the mounting chamber 13 can be used to connect with the aerosol generating device. Therefore, the mounting chamber 13 is also used to match the connection structure of the aerosol generating device. In this embodiment, to accommodate the connection between the filter and the aerosol generating device, the mounting chamber 13 is not centrally located relative to the central axis of the body 1, but rather adaptively offset.

[0067] Please see the appendix Figure 5 Optionally, the body 1 has a first end 15 near the nozzle 2 and a second end 16 away from the nozzle 2, and a side surface 17 extending between the first end 15 and the second end 16, wherein the connecting surface 18 between the side surface 17 and the end face of the second end 16 has a different curvature.

[0068] In this embodiment, the connecting surface 18 between the side surface 17 and the end face of the second end 16 has a larger curvature and a smaller curvature. By constructing the connecting surface 18 between the side surface 17 and the end face of the second end 16 with different curvatures, the body 1 can have a defined insertion angle in the circumferential direction. That is, after the body 1 and the aerosol generating device have a defined relative position, it is convenient for the user to align the filter so that the body 1 can be accurately connected to the aerosol generating device. Furthermore, when the filter is connected to the aerosol generating device, the outlet of the aerosol generating device that outputs the first aerosol can be aligned with the first inlet 14, thereby guiding the first aerosol into the first airflow chamber 11.

[0069] Please continue to refer to the appendix. Figure 2 and attached Figure 3 Optionally, a liquid suction element 6 is also provided in the second airflow chamber 12, and the liquid suction element 6 is located on the side of the filter material 3 facing the suction nozzle 2.

[0070] Specifically, when high-temperature aerosols encounter low-temperature surfaces or when the ambient temperature fluctuates, some aerosols will condense to form condensate. In this embodiment, by placing the liquid-absorbing element 6 on the filter material 3, the capillary action of the liquid-absorbing element 6 can be used to actively adsorb the condensate, preventing it from flowing along the first airflow chamber 11 and the second airflow chamber 12. After adsorption saturation, the liquid-absorbing element 6 can be replaced or cleaned for maintenance. Alternatively, the liquid-absorbing element 6 can also employ a porous structure to intercept and temporarily store the condensate, achieving liquid management through physical adsorption or drainage mechanisms. The liquid-absorbing element 6 can be made of porous materials such as cotton fibers, non-woven fabric, or fiberglass rope.

[0071] This embodiment can prevent leakage accidents by setting up the liquid absorption component 6, and can also further avoid the generation of irritating odors that affect the user experience due to secondary heating, and can also avoid internal short circuit failures.

[0072] Optionally, the outer shell of the body 1 is a transparent structure, or the portion of the outer shell of the body 1 located at the filter material 3 is a transparent structure.

[0073] Specifically, the body 1 can be formed by injection molding, and after molding, it is partially or entirely transparent or semi-transparent, so that the user can clearly observe the aerosol in the first airflow chamber 11 and the second airflow chamber 12 through the body 1.

[0074] In this embodiment, the semi-transparent and fully transparent states of the main body 1 allow the user to observe at any time whether the filter material 3 inside the second airflow chamber 12 is saturated, helping the user to obtain relevant information in a timely manner to determine whether the filter material 3 needs to be replaced.

[0075] Optionally, the installation chamber 13 is provided with a buckle or a slot.

[0076] In this embodiment, in addition to fixing the aerosol generating product 100 when the filter is used alone, the mounting chamber 13 is further used to connect with other structures. By pre-setting buckles and slots in the mounting chamber 13, the filter can be snapped into other structures, improving the convenience and efficiency of the connection.

[0077] Please see the appendix Figure 6 -Appendix Figure 8 The second aspect of this embodiment also relates to an aerosol generating apparatus, which includes a main body 4, an atomizer 7, and a filter. The atomizer 7 is used to atomize a liquid matrix to generate a first aerosol. The filter is removably connected to the main body 4 and is at least partially housed within the main body 4. When the filter is connected to the main body 4, a first airflow chamber 11 communicates with the atomizer 7 to receive the first aerosol, and a second airflow chamber 12 is used to receive a second aerosol produced by an aerosol generating article 100 inserted into the main body 4. Specifically, the main body 4 has an atomizer 7 inside for generating the first aerosol. When the filter is connected to the aerosol generating apparatus, the first air inlet 14 of the first airflow chamber 11 can communicate with the flow channel of the atomizer 7 to introduce the first aerosol into the interior of the first airflow chamber 11. Figure 7 The airflow path R1 is shown in the diagram.

[0078] The atomizer 7 internally stores an atomizing medium. When powered on, the atomizer 7 generates an atomized first aerosol. The atomizer 7 also includes an atomizing element, which comprises a liquid guide and a heating element attached to the liquid guide. The liquid guide draws in the liquid matrix from the storage chamber and transfers it to the heating element, which then heats and atomizes the liquid matrix to generate the first aerosol. The liquid guide can be made of any porous material such as porous ceramics, cotton fibers, non-woven fabric, or fiberglass rope, allowing it to draw in and transfer the liquid matrix through its internal porous structure.

[0079] This aerosol generating device enhances the taste of inhalable aerosols and improves the user experience by connecting a filter to the aerosol generating device to form a mixed inhalation structure.

[0080] Furthermore, the main body 4 is provided with a clamping member 41 for inserting the aerosol generating product 100. The clamping member 41 is provided with a first snap-fit ​​part 411. The main body 4 is provided with an installation chamber 13 for inserting the aerosol generating product 100. The aerosol generating product 100 is used to generate the second aerosol. The inner wall of the installation chamber 13 is provided with a second snap-fit ​​part 132. When the main body 1 is inserted into the main body 4, the first snap-fit ​​part 411 and the second snap-fit ​​part 132 snap-fit ​​together.

[0081] In this embodiment, a plurality of first snap-fit ​​portions 411 are provided on the outer wall of one end of the clamping member 41, and a plurality of second snap-fit ​​portions 132 are provided on the inner wall of the mounting chamber 13. The first snap-fit ​​portions 411 are snap protrusions or buckles, and the second snap-fit ​​portions 132 are buckles, slots or holes for snap-fit ​​engagement.

[0082] When the filter is connected to the aerosol generating device, the first snap-fit ​​part 411 snaps into the second snap-fit ​​part 132. In use, the user can directly insert the aerosol generating product 100 into the main body 4 and clamp and fix the aerosol generating product 100 using the clamping member 41. Figure 7 As shown, the second aerosol generated after the combustion of the aerosol generating product 100 can enter the second airflow chamber 12 along the airflow path R2, so that the first aerosol and the second aerosol can merge and form a mixed aerosol in the nozzle 2.

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.
