The atomizing air supply device 20 is communicated with an atomizing air inlet 34.

In use, the filter body 10 is connected to the main body of an aerosol-generating device, and the smoke inlet 32 is in communication with the smoke tube assembly 200 of the main body. The tube assembly 200 is used to heat the tobacco rods to produce smoke, which is carried in the tube assembly 200 from the smoke inlet 32 into the smoke passage 30. At the same time, the atomizing air supply device 20 supplies atomizing air, which enters the smoke passage 30 through the atomizing air inlet 34, and is mixed with the smoke in the smoke passage 30 to form a mixture of the smoke and the atomizing air, and the mixture is finally discharged through the suction opening 36 for being sucked by the user.

In use, the flue gas in the flue pipe assembly 200 enters the flue gas channel 31 through the flue gas inlet 32, and then enters the gas mixing chamber 35 through the flue gas channel 31. Meanwhile, the atomizing gas in the atomizing gas supply device 20 enters the atomizing gas passage 33 through the atomizing gas inlet 34, and then enters the gas mixing chamber 35 through the atomizing gas passage 33. The atomizing gas mixes with the flue gas in the gas mixing chamber 35 as it enters the gas mixing chamber 35 to form a mixture of atomizing gas and flue gas. The mixture in the gas mixing chamber 35 reaches the suction port 36 through the suction passage 37, and is finally discharged from the suction port 36 for the user to suck.

By providing the gas mixing chamber 35, in a first aspect, the mixture can be mixed in advance in the gas mixing chamber 15 before entering the suction channel 37 for the user to suck, the atomized gas and the smoke gas are mixed more uniformly, and the taste can be improved; in the second aspect, the temperature can drop in the atomizing gas and flue gas mixing process, can avoid scalding the user.

In a first aspect, compactness of the arrangement of the gas mixing channel 39 and the flue gas channel 31 is achieved. In the second aspect, the longer length of the gas mixing channel 39 can be realized in a limited space, so that the path of the mixture flowing through the gas mixing channel 39 is longer, the mixture is mixed more sufficiently, and the phenomenon of taste layering is avoided. The mouthfeel is "stratified", i.e. the mouthfeel of the last bite and the next bite of the puff is not the same, mainly due to the fact that the content of the regulating solution in the mixture is too different. In the third aspect, ensuring the length of the gas mixing channel 39 also ensures sufficient condensation of the mixed gas, thereby avoiding insufficient condensation of the mixed gas from scalding the user.

The flue gas channel 31 comprises an air inlet section 310 and an arc-shaped section 312.

Because the first channel section 390a is circumferentially arranged along the smoke channel 31a, the first channel section 390a and the smoke channel 31a are compactly arranged, the first channel section 390a is longer and is beneficial to fully condensing the mixture, the horizontally arranged third condensation channel 394a can save the vertical space of the filter assembly 100a, the vertically arranged second condensation channel 392a enables the third condensation channel 394a to be arranged above the first channel section 390a, the third channel section is parallel to the plane where the first channel section 390a is located, and the third channel section 394a is compactly arranged with the first channel section 390 a.

An adsorbent member 40a is disposed within first passage section 390a and third passage section 394a for adsorbing condensate formed by condensation of the mixture. Because the second channel section 392a is vertical, the condensate in the second channel section 392a automatically flows into the first channel section 390a under the influence of self-weight and is adsorbed by the adsorbing member 40a in the first channel section 390a, so the adsorbing member 40a does not need to be arranged in the second channel section 392a, and the cost can be reduced.

Referring to fig. 13, fig. 13 is a schematic view of an internal structure of an aerosol generating device according to another embodiment of the present invention. The aerosol-generating device comprises a host machine and the filter assembly 100, 100a provided by the various embodiments described above. The main body includes a smoke tube assembly 200. The smoke tube assembly 200 communicates with the smoke inlets 32, 32a. The smoke tube assembly 200 includes a smoke tube for containing cigarettes, which may be conventional cigarettes, etc., or may be a special cartridge; the heating element is used for heating cigarettes contained in the smoke pipe to generate smoke.

Compared with the prior art, the embodiment of the utility model provides a filter assembly 100, 100a and aerosol generating device, when using, the host computer of aerosol generating device is connected to filter body 10, and flue gas entry 32 communicates the tobacco pipe subassembly 200 of host computer. The smoke tube assembly 200 is used for heating the cigarettes to generate smoke, and the smoke in the smoke tube assembly 200 enters the smoke channel 200 from the smoke inlet 32 and then enters the gas mixing chamber 35 from the smoke channel 31. Meanwhile, the atomizing gas supply device 20 supplies atomizing gas, the atomizing gas enters the atomizing gas passage 33 through the atomizing gas inlet 34, and then enters the gas mixing chamber 35 through the atomizing gas passage 33 to be mixed with the flue gas in the gas mixing chamber 35 to form a mixture of the flue gas and the atomizing gas, and the mixture is finally discharged through the suction opening 36 for being sucked by a user. Through setting up gas mixing chamber 35, on the one hand, the mixture can mix in advance in gas mixing chamber 35 before getting into suction channel 37 and supplying the user's suction, and atomizing gas and flue gas mix comparatively evenly, can improve the taste. In the second aspect, the temperature can drop in the atomizing gas and flue gas mixing process, can avoid scalding the user. Moreover, by providing the smoke passage 30 with the smoke inlet 32 and the atomizing inlet 34, the source of the smoke and the source of the atomizing can be separated, that is, the smoke tube assembly 200 and the atomizing supply device 20 are separated, so that the temperatures of the smoke and the atomizing before entering the smoke passage 30 can be controlled respectively, the temperature difference between the mixed smoke and the atomizing is small, the atomizing and the smoke do not produce excessive condensate when cooled together, and the mouth feeling of smoking can also be ensured.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; within the idea of the invention, also technical features in the above embodiments or in different embodiments can be combined, steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the invention in its corresponding aspects.
