Description

Technical Field

[0001] This application relates to the field of aerosol generation, and more particularly to a filter assembly and an aerosol generation device. Background Technology

[0002] Aerosol generating devices heat an aerosol generating matrix, causing it to produce aerosols for users to inhale. These devices typically include a filter through which users can inhale the generated aerosols.

[0003] When users draw aerosol through the filter, the aerosol always passes through the filter via the shortest path, which may result in insufficient filtration and flavor enhancement, and low utilization of the space inside the filter. Utility Model Content

[0004] The purpose of this application is to provide a filter assembly and an aerosol generating device, which are designed to improve the filtration or aroma enhancement effect of aerosols.

[0005] To achieve the above objectives, this application provides a filter assembly, comprising:

[0006] The filter body has an air inlet channel, an air outlet channel, and a dispersion baffle. The dispersion baffle separates the filter body into a filter chamber and a dispersion chamber. The dispersion baffle has a plurality of first through holes that connect the dispersion chamber and the filter chamber. The air inlet channel is connected to the dispersion chamber, and the air outlet channel is connected to the filter chamber.

[0007] In particular, along the direction away from the air intake channel, the diameter of the plurality of first through holes gradually increases.

[0008] In the filter assembly of this application, the air intake channel is located at the center of one end of the dispersion chamber.

[0009] In the filter assembly of this application, the end of the first through hole facing the dispersion chamber is provided with an air guide hole, and the diameter of the air guide hole gradually decreases along the direction from the dispersion chamber to the filter chamber.

[0010] The filter assembly of this application further includes a filtration structure and / or a flavoring structure, wherein the filtration structure and / or the flavoring structure are disposed within the filter cavity.

[0011] The filter assembly of this application further includes a baffle that divides the filter cavity into a first chamber and a second chamber. The baffle is provided with a plurality of second through holes. The first chamber and the second chamber are connected through the plurality of second through holes. Along the flow direction of the aerosol, the first chamber is located upstream of the second chamber. The first chamber is filled with the filter structure and / or the flavoring structure, and the second chamber is filled with the filter structure and / or the flavoring structure.

[0012] The filter assembly of this application also includes a cover plate, which is disposed on the end of the filter cavity away from the dispersion cavity. The cover plate is provided with a plurality of third through holes, which communicate with the filter cavity.

[0013] In the filter assembly of this application, the filter body includes a filter shell and a suction nozzle, the suction nozzle is provided with the air outlet channel, the filter shell is provided with the dispersion baffle, and the suction nozzle is connected to the filter shell.

[0014] In the filter assembly of this application, the filter body includes a filter shell and an air inlet structure. The filter shell is provided with the dispersion partition. The air inlet structure includes an installation part and an air inlet channel. The installation part is provided with an air inlet groove that opens toward the dispersion partition. The air inlet groove is connected to the air inlet channel. The installation part is connected to the filter shell and together with the dispersion partition forms the dispersion cavity.

[0015] In the filter assembly of this application, the dispersion partition is provided with a fixing post, the mounting part is provided with a fixing hole, and the fixing post is fitted into the fixing hole.

[0016] In the filter assembly of this application, the air intake channel extends in a direction away from the dispersion chamber.

[0017] In the filter assembly of this application, a plurality of first through holes are arranged along the shape of the dispersion partition and are distributed on the dispersion partition.

[0018] This application also provides an aerosol generating apparatus, including a main unit and a filter assembly as described in any of the above;

[0019] The main unit is equipped with a heating component for heating the aerosol generation matrix to generate aerosols. The filter assembly is detachably connected to the main unit. The air inlet channel is connected to the heating component, and the aerosols can enter the dispersion chamber and the filter chamber sequentially through the air inlet channel.

[0020] The filter assembly and aerosol generating device provided in this application allow the user to draw in aerosol through the filter assembly. The aerosol enters through the inlet channel, passes sequentially through the dispersion chamber and the filter chamber, and exits through the outlet channel. When the aerosol flows from the dispersion chamber to the filter chamber, it passes through the first through-hole of the dispersion baffle. During flow, the aerosol initially concentrates near the inlet channel within the dispersion chamber. The closer to the inlet channel, the smaller the diameter of the first through-hole in the dispersion baffle, resulting in greater flow resistance and making it more difficult for the aerosol to flow through the through-hole to the filter chamber. Conversely, the farther away from the inlet channel, the larger the diameter of the first through-hole, resulting in less flow resistance and easier flow. Therefore, the aerosol can easily flow within the dispersion chamber to a location away from the inlet channel, achieving uniform dispersion throughout the dispersion chamber. When the aerosol flows into the filter chamber through the first through hole, it can enter the filter chamber evenly. Therefore, the aerosol can fully contact the filtration structure and / or aroma-enhancing structure in the filter chamber to extend the service life of the filter assembly and improve the filtration or aroma-enhancing effect of the aerosol, thereby improving the user's inhalation experience.

[0042] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] In related technologies, when a user inhales aerosol through a filter, the aerosol passes through the filter via the shortest path. For example, the aerosol enters the filter from the position closest to the air inlet. When the filter filters or enhances the aroma of the aerosol, most of the aerosol only comes into contact with the filtration or aroma-enhancing structures near the air inlet to achieve filtration or aroma enhancement. Therefore, this may result in insufficient aerosol filtration and aroma enhancement, and low space utilization within the filter.

[0044] Therefore, this application provides a filter assembly and an aerosol generating device to improve the filtration or aroma enhancement effect of aerosols.

[0045] like Figure 1 and Figure 2 As shown, the filter assembly 100 provided in this embodiment includes a filter body 10. The filter body 10 has an air inlet channel 132, an air outlet channel 121, and a dispersion partition 111. The dispersion partition 111 divides the filter body 10 into a filter chamber 10b and a dispersion chamber 10a. The dispersion partition 111 has multiple first through holes 111a, which connect the dispersion chamber 10a and the filter chamber 10b. The air inlet channel 132 communicates with the dispersion chamber 10a, and the air outlet channel 121 communicates with the filter chamber 10b. Wherein, as... Figure 3 As shown, along the direction away from the air intake passage 132, the diameter of the plurality of first through holes 111a gradually increases.

[0046] In the above embodiments, since the plurality of first through holes 111a are all provided on the dispersion baffle 111, the statement that the diameter of the plurality of first through holes 111a gradually increases along the direction away from the intake channel 132 refers to the arrangement of the plurality of first through holes 111a on the dispersion baffle 111. Specifically, as... Figure 3As shown, the closer the first through hole 111a is to the air intake channel 132, the smaller its diameter, making it less likely for aerosols to pass through; the farther away the first through hole 111a is from the air intake channel 132, the larger its diameter, making it easier for aerosols to pass through. In this way, the aerosols passing through the dispersion baffle 111 can flow evenly to the filter chamber 10b.

[0047] In the filter assembly 100 of this application embodiment, when the user draws in aerosol through the filter assembly 100, the aerosol enters from the air inlet channel 132, passes through the dispersion chamber 10a and the filter chamber 10b in sequence, and flows out from the air outlet channel 121. When the aerosol flows from the dispersion chamber 10a to the filter chamber 10b, it passes through the first through-hole 111a of the dispersion baffle 111. During flow, the aerosol initially concentrates at a position in the dispersion chamber 10a near the air inlet channel 132. The closer to the air inlet channel 132, the smaller the aperture of the first through-hole 111a of the dispersion baffle 111, resulting in greater flow resistance and making it more difficult for the aerosol to flow through the first through-hole 111a to the filter chamber 10b. Conversely, the farther away from the air inlet channel 132, the larger the aperture of the first through-hole 111a of the dispersion baffle 111, resulting in less flow resistance and easier flow. Therefore, the aerosol can flow relatively easily within the dispersion chamber 10a to a position away from the air inlet channel 132, thus achieving uniform dispersion throughout the dispersion chamber 10a. When the aerosol flows through the first through hole 111a to the filter chamber 10b, it can enter the filter chamber 10b evenly. Therefore, the aerosol can fully contact the filtration structure 51 and / or the aroma-enhancing structure 52 in the filter chamber 10b, so as to extend the service life of the filter assembly 100 and improve the filtration or aroma-enhancing effect of the aerosol, thereby improving the user's inhalation experience.

[0048] like Figure 2 As shown, in some embodiments, the air inlet channel 132 is located at the center of one end of the dispersion chamber 10a. When the aerosol enters the dispersion chamber 10a from the air inlet channel 132, since the air inlet channel 132 is centrally located, the aerosol can flow towards the periphery of the air inlet channel 132 under the action of the dispersion baffle 111 when it initially enters the dispersion chamber 10a, so as to flow to all parts of the dispersion chamber 10a faster and more evenly, and then enter the filter chamber 10b faster and more evenly through the multiple first through holes 111a.

[0049] It should be noted that the center of one end of the dispersion cavity 10a mentioned here can be understood as the center of the shape of the dispersion cavity 10a perpendicular to the cross-section of the intake passage 132. For example, when the shape of the cross-section of the dispersion cavity 10a perpendicular to the intake passage 132 is circular, the center is the center of the circle; when the shape of the cross-section of the dispersion cavity 10a perpendicular to the intake passage 132 is polygonal, the center is the center of the circumcircle of the polygon; when the shape of the cross-section of the dispersion cavity 10a perpendicular to the intake passage 132 is elliptical, the center is the center of symmetry of the ellipse. Figure 2 and Figure 3 As shown, in some embodiments, the dispersion cavity 10a has an arc-shaped extension. In this case, the center is located at a position where the distance to both ends of the dispersion cavity 10a in its length extension direction is the same, and the distance to both ends of the dispersion cavity 10a in the vertical direction of its length extension is the same.

[0050] Of course, in other embodiments, the air intake channel 132 can also be configured according to the specific structure of the filter assembly 100, as long as the air intake channel 132 can cooperate with the main unit 200 of the aerosol generating device, without limitation. For example, the air intake channel 132 can also be located on one side of one end of the dispersion chamber 10a.

[0051] like Figure 3 As shown, in some embodiments, the end of the first through hole 111a facing the dispersion chamber 10a is provided with a guide hole 111b. Along the direction from the dispersion chamber 10a to the filter chamber 10b, the diameter of the guide hole 111b gradually decreases. The side of the guide hole 111b facing the dispersion chamber 10a is flared. When the aerosol flows from the dispersion chamber 10a to the filter chamber 10b, the flared guide hole 111b can guide the aerosol flow, allowing the aerosol to flow quickly and smoothly into the filter chamber 10b, thus improving the aerosol flow efficiency. It should be noted that the diameter variation of the multiple first through holes 111a includes the diameter variation of the guide holes 111b. That is, the closer the guide hole 111b is to the first through hole 111a of the air intake channel 132, the smaller its overall diameter; the farther the guide hole 111b is from the first through hole 111a of the air intake channel 132, the larger its overall diameter. Of course, in other embodiments, the first through hole 111a may also be a cylindrical hole, and the diameter of the first through hole 111a does not change along the direction from the dispersion cavity 10a to the filter cavity 10b.

[0052] like Figure 2 and Figure 3As shown, in some embodiments, the filter assembly 100 further includes a filter structure 51. The filter structure 51 is disposed within the filter cavity 10b. The filter structure 51 can filter aerosols to remove impurities and improve the user's inhalation experience. After the aerosol passes through the dispersion partition 111, the aerosol can be evenly dispersed to various positions in the filter cavity 10b. When it passes through the filter structure 51, each position of the filter structure 51 can contact the aerosol to filter it. In this way, the aerosol can be fully filtered, thereby improving the user's inhalation experience. Furthermore, the filter structure 51 can make uniform contact with the aerosol, making full use of the filter structure 51 within the filter cavity 10b and avoiding situations where some filter structures 51 are not used. Therefore, the service life of the filter structure 51 can be increased, thereby increasing the service life of the filter assembly 100.

[0053] For example, the filter structure 51 includes ceramic particles, which can adsorb large particles, acidic gases and heavy metal gases in the aerosol to improve the taste of the aerosol inhaled by the user and ensure the user's inhalation experience.

[0054] For example, the filter structure 51 includes activated carbon, which can adsorb large particles, acidic gases and heavy metal gases in the aerosol to improve the taste of the aerosol inhaled by the user and ensure the user's inhalation experience.

[0055] like Figure 2 and Figure 3 As shown, in some embodiments, the filter assembly 100 further includes a flavoring structure 52. The flavoring structure 52 is disposed within the filter cavity 10b. The flavoring structure 52 can flavor the aerosol to improve the user's inhalation experience. After the aerosol passes through the dispersion partition 111, the aerosol can be evenly dispersed to various positions in the filter cavity 10b. When it passes through the flavoring structure 52, each position of the flavoring structure 52 can contact the aerosol to adjust its flavor. This allows the aerosol to be fully flavored, thereby improving the user's inhalation experience. Furthermore, the flavoring structure 52 can make uniform contact with the aerosol, fully utilizing the flavoring structure 52 within the filter cavity 10b and avoiding any unused portions of the flavoring structure 52. This extends the lifespan of the flavoring structure 52, and consequently, the lifespan of the filter assembly 100.

[0056] For example, the flavoring structure 52 includes plant fiber particles adsorbed with tobacco flavoring. When the aerosol flows through the plant fiber particles, it can carry out the tobacco flavoring adsorbed in the plant fiber particles to adjust the flavor of the aerosol and achieve flavoring of the aerosol.

[0057] like Figure 2As shown, in some embodiments, the filter assembly 100 further includes a baffle 20, which divides the filter chamber 10b into a first chamber 10c and a second chamber 10d. The baffle 20 has a plurality of second through holes 20a, through which the first chamber 10c and the second chamber 10d are connected. Along the flow direction of the aerosol, the first chamber 10c is located upstream of the second chamber 10d. The first chamber 10c is filled with a filter structure 51 and / or a fragrance-enhancing structure 52, and the second chamber 10d is filled with a filter structure 51 and / or a fragrance-enhancing structure 52. The baffle 20 can divide the filter chamber 10b into two independent chambers, so that the first chamber 10c and the second chamber 10d can stably accommodate the filter structure 51 and / or the fragrance-enhancing structure 52, respectively. After the aerosol is uniformly dispersed and flows into the filter chamber 10b, it flows sequentially into the first chamber 10c to fully contact the filter structure 51 and / or flavoring structure 52 of the first chamber 10c. Then, it passes through the multiple second through-holes 20a of the baffle 20 and flows into the second chamber 10d to fully contact the filter structure 51 and / or flavoring structure 52 of the second chamber 10d. This structure ensures sufficient contact between the aerosol and the filter structure 51 and / or flavoring structure 52 of each chamber, allowing for thorough filtration or flavoring of the aerosol and maximizing the utilization of the filter structure 51 and / or flavoring structure 52, thereby extending the service life of the filter structure 51 and / or flavoring structure 52 in each chamber.

[0058] For example, the first chamber 10c is filled with a filter structure 51, and the second chamber 10d is filled with a flavoring structure 52.

[0059] For example, a plurality of second through holes 20a are distributed on the baffle 20 so that the aerosol at each point of the first chamber 10c can pass through the baffle 20 and flow evenly to the second chamber 10d, so as to achieve full contact between the filtration structure 51 and / or the aroma-enhancing structure 52 of the second chamber 10d.

[0060] like Figure 2 As shown, in some embodiments, the filter assembly 100 further includes a cover plate 30, which covers the end of the filter cavity 10b away from the dispersion cavity 10a. The cover plate 30 has a plurality of third through holes 30a communicating with the filter cavity 10b. The cover plate 30 can separate the filter cavity 10b so that the filter structure 51 and / or the flavoring structure 52 can be stably housed within the filter cavity 10b. After the aerosol comes into full contact with the filter structure 51 and / or the flavoring structure 52 within the filter cavity 10b, it can pass through the plurality of third through holes 30a of the cover plate 30 and flow to the air outlet channel 121 for inhalation by the user.

[0061] For example, a plurality of third through holes 30a are distributed on the cover plate 30 so that aerosols in all parts of the filter chamber 10b can pass through the cover plate 30 and flow out of the filter chamber 10b for the user to inhale.

[0062] like Figure 2 and Figure 3 As shown, in some embodiments, the filter body 10 includes a filter housing 11 and a suction nozzle 12. The suction nozzle 12 is provided with an air outlet channel 121, and the filter housing 11 is provided with a dispersion partition 111. The suction nozzle 12 is connected to the filter housing 11. After the aerosol and the filtration structure 51 and / or the flavoring structure 52 in the filter cavity 10b have made sufficient contact, the aerosol flows out of the filter cavity 10b and flows to the air outlet channel 121, where it is inhaled by the user.

[0063] like Figure 2 and Figure 3 As shown, in some embodiments, the filter housing 11 includes an outer shell 112 and a dispersion partition 111, with the dispersion partition 111 disposed within the outer shell 112. The dispersion partition 111 and the outer shell 112 are integrally formed, ensuring the overall structure of the filter housing 11 is stable and reliable, while also facilitating the assembly of the filter nozzle assembly 100. A baffle 20 and a cover 30 are sequentially and transversely arranged within the outer shell 112 along its length, and are positioned opposite to the dispersion partition 111 along the length of the outer shell 112. Figure 2 As shown, the cover plate 30, the dispersion partition 111, and the outer shell 112 together form a filter chamber 10b; the dispersion partition 111, the baffle 20, and the outer shell 112 together form a first chamber 10c; and the baffle 20, the cover plate 30, and the outer shell 112 together form a second chamber 10d. The suction nozzle 12 is connected to one end of the outer shell 112 to connect the exhaust channel 121 and the filter chamber 10b.

[0064] like Figure 2 and Figure 3 As shown, in some embodiments, the filter assembly 100 further includes a seal 40 disposed within the housing 112 and along the length of the housing 112 on the side of the cover plate 30 away from the filter chamber 10b. For example, the seal 40 is made of sealing silicone. The periphery of the seal 40 is fitted into the inner wall of the housing 112, and one end of the seal 40 abuts against the cover plate 30, so that the cover plate 30 can be stably installed within the housing 112. The seal 40 has a groove opening toward the cover plate 30, and the bottom of the groove has multiple fourth through holes 40a. The groove and the cover plate 30 together form a flow chamber 10e. When the aerosol flows out of the filter chamber 10b from the multiple third through holes 30a of the cover plate 30, it enters the flow chamber 10e and passes through the multiple fourth through holes 40a to flow to the air outlet channel 121 for the user to inhale. The seal 40 can further limit the flow direction of the aerosol, ensuring that the aerosol can flow smoothly from the filter chamber 10b to the outlet channel 121, and preventing the aerosol from overflowing from the side.

[0065] For example, a plurality of fourth through holes 40a of the seal 40 are distributed on the bottom of the groove so that the aerosol can pass smoothly through the seal 40 and flow to the venting channel 121 for the user to inhale.

[0066] For example, the suction nozzle 12 is connected to one end of the housing 112 and surrounds the periphery of the seal 40. This allows the seal 40 to seal the connection between the suction nozzle 12 and the housing 112, preventing aerosol leakage.

[0067] like Figure 2 and Figure 3 As shown, in some embodiments, the filter body 10 further includes an air inlet structure 13. The filter housing 11 is provided with a dispersion baffle 111. The air inlet structure 13 includes an mounting part 131 and an air inlet channel 132. The mounting part 131 is provided with an air inlet groove that opens toward the dispersion baffle 111. The air inlet groove is connected to the air inlet channel 132. The mounting part 131 is connected to the filter housing 11 and together with the dispersion baffle 111, forms a dispersion cavity 10a. After the aerosol enters from the air inlet channel 132, it can flow to the dispersion cavity 10a formed by the mounting part 131 and the dispersion baffle 111. Under the action of the dispersion baffle 111, the aerosol can be evenly dispersed to all parts of the dispersion cavity 10a. After passing through multiple first through holes 111a, it can evenly enter the filter cavity 10b to fully contact the filter structure 51 and / or the aroma-enhancing structure 52 in the filter cavity 10b.

[0068] For example, the periphery of the mounting portion 131 is fitted into the inner wall of the housing 112, and one end of the mounting portion 131 facing the dispersion partition 111 abuts against the dispersion partition 111. In this way, the mounting portion 131 can be tightly connected to the filter housing 11, and a seal is formed between the mounting portion 131 and the filter housing 11 to prevent aerosol from leaking out from the connection point. For example, the mounting portion 131 is made of sealing silicone.

[0069] like Figure 3 As shown, in some embodiments, the dispersion partition 111 is provided with a fixing post 1111, and the mounting part 131 is provided with a fixing hole (not shown), and the fixing post 1111 is fitted into the fixing hole. The mounting part 131 can be stably connected to the filter housing 11 through the assembly connection of the fixing hole and the fixing post 1111, so as to ensure that the filter body 10 can be used reliably.

[0070] For example, the fixing post 1111 is located at the edge of the dispersion partition 111, and the fixing hole is located outside the mounting groove of the mounting part 131. When the mounting part 131 is connected to the filter shell 11 through the fixing hole and the fixing post 1111, the connection structure between the two can be used to avoid affecting the flow of aerosol, so as to ensure that the aerosol can be uniformly dispersed and flow.

[0071] like Figure 4 As shown, in some embodiments, the air intake channel 132 extends in a direction away from the dispersion chamber 10a. When the filter assembly 100 is mounted on the aerosol generating device, the air intake channel 132 of the filter assembly 100 communicates with the heating assembly. In general aerosol generating devices, a support is provided in the heating assembly to limit the insertion position of the aerosol generating matrix. During use, carbon accumulates in the support within the heating assembly, making cleaning difficult. In this embodiment, the air intake channel 132 is extended, allowing it to penetrate deep into the heating assembly, with its end abutting against the end of the aerosol generating matrix. This limits the insertion position of the aerosol generating matrix when using the aerosol generating device, preventing excessive insertion and eliminating the need for a support. Furthermore, when removing the filter assembly 100 from the aerosol generating device, the extended air intake channel 132 can also remove carbon deposits from the heating assembly, facilitating cleaning of the aerosol generating device.

[0072] For example, the air intake channel 132 is also provided with a stepped portion. When the filter assembly 100 is assembled with the aerosol generating device, the stepped portion can limit the position of the air intake channel 132 to achieve a stable installation of the filter assembly 100.

[0073] In some other embodiments, the air intake channel 132 may not be extended; it is sufficient to ensure that it is connected to the heating component when the filter assembly 100 is mounted on the aerosol generating device.

[0074] like Figure 3 As shown, in some embodiments, a plurality of first through holes 111a are arranged along the shape of the dispersion partition 111 and cover the dispersion partition 111. It should be noted that the arrangement of the plurality of first through holes 111a is based on the shape of the dispersion partition 111 to ensure that aerosols can pass through at all positions of the dispersion partition 111. In this way, under the action of the dispersion partition 111, the aerosol can be evenly dispersed to all parts of the dispersion cavity 10a, so that when the aerosol flows through the plurality of first through holes 111a to the filter cavity 10b, it can fully contact the filter structure 51 and / or the aroma-enhancing structure 52 at various positions in the filter cavity 10b.

[0075] like Figure 3 As shown, in some embodiments, the dispersion partition 111 extends in an arc shape. A plurality of first through holes 111a are arranged at intervals along the extended shape of the dispersion partition 111 to cover the entire dispersion partition 111. Exemplarily, the dispersion cavity 10a and the filter cavity 10b are also arc-shaped, with the air intake channel 132 located at the center of one end of the dispersion cavity 10a. Along a direction away from the center of the dispersion partition 111, the diameter of the plurality of first through holes 111a gradually increases.

[0076] In other embodiments, the dispersion partition 111 is circular in shape. The plurality of first through holes 111a comprises a plurality of first through hole groups, which are arranged sequentially around the center of the dispersion partition 111, with each first through hole group having multiple first through holes 111a spaced around the center of the circle according to its outline. This ensures that the plurality of first through holes 111a cover the dispersion partition 111. Exemplarily, the dispersion cavity 10a and the filter cavity 10b are also circular in shape, with the air intake channel 132 located at the center of one end of the dispersion cavity 10a. Along a direction away from the center of the dispersion partition 111, the diameter of the plurality of first through holes 111a gradually increases.

[0077] In some other embodiments, the dispersion baffle 111 is rectangular in shape. A plurality of first through holes 111a are arranged in a matrix pattern, horizontally and vertically, covering the dispersion baffle 111. Exemplarily, the dispersion cavity 10a and the filter cavity 10b are also rectangular in shape, with the air intake channel 132 located at the center of one end of the dispersion cavity 10a. Along a direction away from the center of the dispersion baffle 111, the diameter of the plurality of first through holes 111a gradually increases.

[0078] In some embodiments, the dispersion partition 111 is elliptical in shape. The plurality of first through holes 111a comprises a plurality of first through hole groups, which are arranged sequentially around the center of the dispersion partition 111, with each first through hole group having multiple first through holes 111a spaced around the center of the ellipse according to its contour. This ensures that the plurality of first through holes 111a cover the dispersion partition 111. Exemplarily, the dispersion cavity 10a and the filter cavity 10b are also elliptical in shape, with the air intake channel 132 located at the center of one end of the dispersion cavity 10a. Along a direction away from the center of the dispersion partition 111, the diameter of the plurality of first through holes 111a gradually increases.

[0079] like Figure 5 As shown in the figure, this application embodiment also provides an aerosol generating device, including a main unit 200 and a filter assembly 100.

[0080] The main unit 200 is equipped with a heating component (not shown) to heat the aerosol generation matrix to generate aerosol. The filter assembly 100 and the main unit 200 are detachably connected. The air inlet channel 132 is connected to the heating component, and the aerosol can enter the dispersion chamber 10a and the filter chamber 10b in sequence through the air inlet channel 132.

[0081] In the aerosol generating apparatus of this application embodiment, the heating component heats the aerosol generating mechanism to generate aerosol. The aerosol enters from the air inlet channel 132, passes through the dispersion chamber 10a and the filter chamber 10b in sequence, and flows out from the air outlet channel 121. When the aerosol flows from the dispersion chamber 10a to the filter chamber 10b, it passes through the first through-hole 111a of the dispersion baffle 111. During flow, the aerosol initially concentrates at a position in the dispersion chamber 10a near the air inlet channel 132. The closer to the air inlet channel 132, the smaller the aperture of the first through-hole 111a of the dispersion baffle 111, resulting in greater flow resistance and making it more difficult for the aerosol to flow through the first through-hole 111a to the filter chamber 10b. Conversely, the farther away from the air inlet channel 132, the larger the aperture of the first through-hole 111a of the dispersion baffle 111, resulting in less flow resistance and easier flow. Therefore, the aerosol can flow relatively easily within the dispersion chamber 10a to a position away from the air inlet channel 132, thus achieving uniform dispersion throughout the dispersion chamber 10a. When the aerosol flows through the first through hole 111a to the filter chamber 10b, it can enter the filter chamber 10b evenly. Therefore, the aerosol can fully contact the filtration structure 51 and / or the aroma-enhancing structure 52 in the filter chamber 10b, so as to extend the service life of the filter assembly 100 and improve the filtration or aroma-enhancing effect of the aerosol, thereby improving the user's inhalation experience.
