[0030] In view of the above problems, the embodiments of the present application provide a filter assembly and an aerosol generating device, which can reduce harmful substances contained in smoke while also taking into account the taste.

[0031] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0032] Figure 1 is a structural schematic diagram of the filter assembly shown in the embodiments of the present application.

[0033] Referring to Figure 1 , the first aspect of the present application provides a filter assembly, which comprises a main body 1, an odor generating unit 2, a filter 3 and a movable element 4. The main body 1 is formed with an air passage 11, an air inlet 12 and an air outlet 13, the air inlet 12 and the air outlet 13 are respectively communicated with the air passage 11, and aerosol can enter the air passage 11 from the air inlet 12 and then flow out from the air outlet 13. The user can align the air outlet 13 with the oral cavity and suck the aerosol flowing out of the air outlet 13.

[0034] The smell generating unit 2 is arranged in the air channel 11, and the smell generating unit 2 contains a flavoring medium. When the smell generating unit 2 is acted upon, the smell generating unit 2 can release the flavoring medium inside, and the flavoring medium diffuses into the aerosol in the air channel 11 and mixes with the aerosol in the air channel 11. The aerosol mixed with the flavoring medium can flow out from the air outlet 13.

[0035] The filter 3 is arranged in the air channel 11, and the filter 3 is used to filter harmful substances in the aerosol, so as to reduce the harmful substances inhaled by the user. The movable element 4 is arranged in the air channel 11, and the movable element 4 can move under the action of an external force and act on the smell generating unit 2, so as to make the smell generating unit 2 release the flavoring medium. When the filter tip assembly is not used, the smell generating unit 2 will not release the flavoring medium. When the user needs to use the filter tip assembly, an external force can be applied to the movable element 4, so that the smell generating unit 2 releases the flavoring medium under the action of the movable element 4. The flavoring medium mixes into the aerosol in the air channel 11, and the user inhales the aerosol mixed with the flavoring medium from the air outlet 13.

[0036] In some embodiments, the movable element 4 can move under the action of an external force and act on the smell generating unit 2, so as to make the smell generating unit 2 release the flavoring medium. The movable element 4 can act on the smell generating unit 2 in the form of extruding or piercing the smell generating unit 2, so as to make the smell generating unit 2 release the flavoring medium.

[0037] In some embodiments, the smell generating unit 2 is a burst bead containing a flavoring medium. When the burst bead is pressed or pierced, the flavoring medium inside is released to flavor the aerosol. The flavoring medium can be selected according to requirements, and the flavoring medium can be mint, tea, fruit, etc., which is not limited herein.

[0038] The movable element 4 can act on the smell generating unit 2 in the form of extruding the smell generating unit 2. Taking the movable element 4 extruding the smell generating unit 2 as an example, the filter tip assembly further comprises an extruding element 5 arranged in the air channel 11. The movable element 4 can move towards the smell generating unit 2 in the air channel 11 under the action of an external force, so that the movable element 4 and the extruding element 5 extrude the smell generating unit 2 together, so as to make the smell generating unit 2 release the flavoring medium.

[0039] The filter 3 and the smell generating unit 2 are arranged in the air channel 11, so that the filter 3 can filter the aerosol passing through the air channel 11, thereby reducing the harmful substances inhaled by the user. The movable element 4 acts on the smell generating unit 2, so that the smell generating unit 2 releases the flavoring medium and mixes into the smoke, enriches the taste of the smoke, reduces the taste loss of the aerosol caused by the filtering of the filter 3, and can also take into account the taste while reducing the harmful substances contained in the aerosol.

[0040] In some embodiments, the filter 3 can be made of porous materials such as ceramic particles, activated carbon, etc. to adsorb large particles, heavy metals and acid gases in the aerosol.

[0041] The pressing member 5 is located on the side of the smell generating unit 2 away from the moving member 4, and the smell generating unit 2 is located between the moving member 4 and the pressing member 5. When the moving member 4 acts on the smell generating unit 2, the moving member 4 and the pressing member 5 jointly press the smell generating unit 2, so that the smell generating unit 2 releases the flavoring medium. The smell generating unit 2 can be fixed to the moving member 4, and the moving member 4 can drive the smell generating unit 2 to abut against the pressing member 5 under the action of external force. The smell generating unit 2 can also be fixed to the pressing member 5, and the moving member 4 moves towards the pressing member 5 and abuts against the smell generating unit 2 fixed to the pressing member 5.

[0042] In some embodiments, the pressing member 5 is provided with a piercing structure which can be a needle-shaped structure, a spherical structure or a knife-shaped structure. When the moving member 4 moves towards the pressing member 5 under the action of external force, the moving member 4 drives the smell generating unit 2 to move towards the pressing member 5, so that the smell generating unit 2 contacts the piercing structure on the pressing member 5. The moving member 4 continues to move, so that the smell generating unit 2 is pierced to release the flavoring medium.

[0043] In some embodiments, the pressing member 5 can be a separate part or can be integrally formed with the main body 1.

[0044] In some embodiments, the smell generating unit 2 is fixed to the moving member 4. In order to better fix the smell generating unit 2, the side of the moving member 4 facing the pressing member 5 is provided with a receiving groove 41, and the smell generating unit 2 is located in the receiving groove 41. This ensures that the smell generating unit 2 can move with the moving member 4 and can be accurately pressed by the pressing member 5.

[0045] The moving member 4 is provided with a cavity 42, and the moving member 4 is provided with an air inlet hole 45 and an air outlet hole 46. The cavity 42 communicates with the air inlet hole 45 and the air outlet hole 46, respectively. The filter 3 is arranged in the cavity 42. The air inlet hole 45 communicates with the air inlet 12, and the air outlet hole 46 communicates with the air channel 11. The aerosol can enter the air channel 11 from the air inlet 12, then enter the cavity 42 through the air inlet hole 45, so that the filter 3 filters the aerosol. The filtered aerosol reflows into the air channel 11 from the cavity 42 through the air outlet hole 46, and then contacts the smell generating unit 2. By arranging the cavity 42 in the moving member 4 to accommodate the filter 3, the space in the air channel 11 is saved, so that the filter 3 can move with the moving member 4, and it is ensured that the filter 3 does not affect the movement of the moving member 4.

[0046] The air inlet 12, the filter 3, the odor generating unit 2 and the air outlet 13 are sequentially arranged along the flow path of the aerosol. The filter 3 is arranged between the air inlet 12 and the odor generating unit 2, so that the flavoring medium released by the odor generating unit 2 is not filtered by the filter 3, and the flavoring medium released by the odor generating unit 2 can reach the user's oral cavity through the air outlet 13.

[0047] The main body 1 is provided with a blocking portion 14 located at the air inlet 12. The blocking portion 14 is used to limit the disengagement of the movable piece 4 from the air inlet 12. In some embodiments, the blocking portion 14 is an annular end edge, and the aperture diameter of the blocking portion 14 is smaller than the diameter of the movable piece 4, so that the movable piece 4 cannot pass through the air inlet 12. In some embodiments, the blocking portion 14 can be a protrusion located on the inner surface of the main body 1, and the blocking portion 14 can resist the outward movement of the movable piece 4 from the air inlet 12.

[0048] The movable piece 4 comprises a shell 43 and a cover 44 connected to each other. The receiving groove 41 is arranged on the shell 43, and the shell 43 and the cover 44 jointly define the cavity 42. The air inlet hole 45 is arranged on the cover 44, and the air outlet hole 46 is arranged on the shell 43. The cover 44 is detachably mounted on the shell 43. When the movable piece 4 is assembled, the filter 3 can be first loaded into the cavity 42, and then the cover 44 and the shell 43 are assembled together, so as to avoid the filter 3 from falling out of the cavity 42.

[0049] In some embodiments, in order to facilitate the assembly of the movable piece 4, the filter 3 and the main body 1, the cover 44 is made of elastic material, and the cover 44 can be deformed. Preferably, the cover 44 is made of silica gel or rubber. When the movable piece 4 is assembled into the main body 1, the shell 43 can be first loaded into the air channel 11 from the air outlet 13, and then the filter 3 is loaded into the cavity 42 from the air inlet 12. Then, the cover 44 is deformed and inserted into the air channel 11 from the air inlet 12, and the cover 44 and the shell 43 are assembled together. The cover 44 is disc-shaped, and the diameter of the cover 44 is the same as the inner diameter of the main body 1. The cover 44 is attached to the inner surface of the main body 1. When no external force is applied to the movable piece 4, the shell 43 can be stopped in the air channel 11 by the friction between the cover 44 and the main body 1, and the shell 43 will not move towards the pressing piece 5, so as to avoid that the movable piece 4 acts on the odor generating unit 2 to release the flavoring medium from the odor generating unit 2 in advance when the filter tip assembly is not used. In some embodiments, the cover 44 can be made of hard material. In this case, the filter 3 is first loaded into the shell 43, and then the cover 44 is mounted on the shell 43. Finally, the entire movable piece 4 together with the filter 3 is loaded into the air channel 11.

[0050] Figure 2 FIG. 1 is a structural schematic diagram of a cooling piece according to an embodiment of the present application.

[0051] Referring to Figures 1-2The filter assembly further comprises a cooling member 6 arranged in the air channel 11, which is used to cool the aerosol to avoid the user from being scalded by the aerosol when inhaling the aerosol, and the cooled aerosol can provide a better taste for the user. The cooling member 6 can be arranged between the air outlet 13 and the movable member 4, or arranged between the movable member 4 and the air inlet 12, or arranged in the cavity 42.

The aerosol can enter the cooling channel from the air channel 11, the aerosol can be cooled in the cooling channel, and the cooled aerosol can be supplied to the user from the air outlet 13.

[0054] In some embodiments, the extrusion member 5 can be connected to one end of the cooling member 6 close to the movable member 4, and the extrusion member 5 and the cooling member 6 can also be two independent components.

[0055] In some embodiments, the cooling channel is a labyrinth channel. The aerosol flows in the cooling channel and constantly exchanges heat with the cooling member 6, thereby reducing the temperature of the aerosol.

[0056] In some embodiments, the cooling member 6 comprises an air inlet portion 61, a first baffle 62, a second baffle 63 and an air outlet portion 64 arranged in the air channel 11 in sequence.

The first gap 621 is staggered with the first through hole 611 and the second gap 631, and the second through hole 641 is staggered with the second gap 631. The first through hole 611, the first gap 621, the second gap 631 and the second through hole 641 form a cooling air channel 11 for cooling the gas.

[0057] In some embodiments, the air inlet part 61 is a cylindrical structure, the extrusion piece 5 is located in the air inlet part 61, when the movable piece 4 moves towards the air outlet 13, the accommodation groove 41 can bring the odor generating unit 2 into the air inlet part 61, so that the extrusion piece 5 extrudes and breaks the odor generating unit 2, the flavoring medium is mixed with the aerosol, the aerosol mixed with the flavoring medium passes through the first through hole 611 to the gap between the first baffle 62 and the air inlet part 61, and then passes through the first gap 621 after being cooled by the first baffle 62, reaches the gap between the first baffle 62 and the second baffle 63, and then passes through the second gap 631 after being cooled by the second baffle 63, and then passes through the second through hole 641 into the air outlet part 64, and finally is supplied to the user from the air outlet 13 after being cooled by the air outlet part 64. The first gap 621 is staggered with the first through hole 611 and the second gap 631, which can prolong the length of the cooling channel 11, thereby improving the cooling effect of the aerosol. The second through hole 641 is staggered with the second gap 631, which can also prolong the length of the cooling channel 11, thereby improving the cooling effect of the aerosol.
