Referring to fig. 4, in some embodiments, the filter 200 may include a filter element 201. For example, referring to fig. 5, the filter element 201 includes a housing 2011 and a cover 2012, the chamber 30 is formed on the housing 2011, the cover 2012 covers the housing 2011, and the cover 2012 cooperates with the housing 2011 to form the chamber 30, so that the structure is simple and the assembly is convenient.

Illustratively, the cover 2012 is made of silica gel, and the cover 2012 is made of silica gel, which is beneficial to realizing tight connection between the cover 2012 and the container 2011, thereby improving connection reliability.

In some embodiments, the air inlet 10, the air outlet 20 and the chamber 30 are formed in the filter element 201, and in particular, the filter element 201 with the air inlet 10, the air outlet 20 and the chamber 30 formed therein can be used as the filter 200, so that the structure is simple and the cost is low.

The structure is compact, the gas circuit is simple, and the assembly is convenient.

It will be appreciated that the number of the filter elements 201 and the receiving spaces 204 may be set according to actual requirements, for example, one, two, three or more. Illustratively, the number of cartridges 201 is provided in a one-to-one correspondence with the number of chambers 30.

Referring to fig. 4 and 6, the number of the receiving spaces 204 and the filter elements 201 is illustratively at least two, such as two, three or more, respectively. Each of the accommodation spaces 204 accommodates therein one filter cartridge 201, and the first housing 202 is detachably connected to the second housing 203. In this way, when one of the filter elements 201 reaches the upper limit of use, the first housing 202 and the second housing 203 can be detached, the filter element 201 with the upper limit of use is replaced by another filter element 201, and then the first housing 202 and the second housing 203 are assembled and connected, so that the quick replacement of the filter element 201 can be realized, the first housing 202 and the second housing 203 do not need to be replaced, and the loss of components is reduced.

Referring to fig. 3 and 6, in some embodiments, the solid particles 40 include a number of filter particles 41 and a number of flavor-enhancing particles 42, the filter particles 41 being used to filter the aerosol; the flavour enhancing particles 42 are adsorbed with a flavour enhancing substance, the flavour enhancing particles 42 being adapted to release the flavour enhancing substance to the aerosol flowing therethrough. Wherein both the filter particles 41 and the flavour enhancing particles 42 exchange heat with the aerosol flowing therethrough, and the number of flavour enhancing particles 42 is located downstream of the number of filter particles 41 in the flow direction of the aerosol. In this way, the plurality of filter particles 41 can filter large-particle harmful substances and tar in the flowing aerosol, and prevent the odor-increasing particles 42 from being influenced by the adsorption of a large amount of substances (such as harmful substances, etc.) by the odor-increasing particles 42, so as to ensure the flavoring effect of the odor-increasing particles 42 on the flowing aerosol, and further ensure that the aerosol flowing out from the air outlet 20 has good taste. It can be understood that the aerosol flows through the filter particles 41 and then flows through the flavor enhancement particles 42, the filter particles 41 can provide a purer environment for the flavor enhancement particles 42, the adsorption and filtration pressure of the flavor enhancement particles 42 is relieved, the problem that the flavor enhancement substances are difficult to release after the flavor enhancement particles 42 adsorb a large amount of substances is avoided, the environment for fully releasing the flavor enhancement substances is provided for the flavor enhancement particles 42, the flavor enhancement particles 42 can fully release the flavor enhancement substances, and therefore good filtering effect and flavoring effect are guaranteed, consistency of front taste and back taste is guaranteed, suction taste is better, and the use experience of users is further improved.

Illustratively, the volume V1 of the number of filter particles 41 satisfies: 10 cm 3 is greater than or equal to V1 and greater than or equal to 0.15 cm 3, such as 0.15 cm 3, 0.3 cm 3, 5 cm 3, 10 cm 3 or any other suitable value between 0.15 cm 3 and 10 cm 3. The volume V2 of the number of flavour enhancing particles 42 satisfies: 15 cm 3 is greater than or equal to V2 and greater than or equal to 0.15 cm 3, such as 0.15 cm 3, 1 cm 3, 1.4 cm 3, 6 cm 3, 15 cm 3 or any other suitable value between 0.15 cm 3 and 15 cm 3. In some embodiments, V2 > V1 may be used to enhance the flavor enhancement effect.

Referring to fig. 6, in some embodiments, the filter particles 41 are positioned in the chamber 30 adjacent to the air inlet 10 in the flow direction of the aerosol, so as to facilitate the filtration at the air inlet 10 and reduce the influence of the impurity gas. The flavor-enhancing particles 42 are positioned in the chamber 30 adjacent to the air outlet 20 so as to release the fragrance during the air outlet and avoid waste of the flavor-enhancing substance.

Referring to fig. 3 and 6, in some embodiments, a baffle 50 is disposed between the air inlet 10 and the air outlet 20, the filter particles 41 and the flavoring particles 42 are respectively located at two sides of the baffle 50, and the baffle 50 can separate the filter particles 41 and the flavoring particles 42 in different spaces of the chamber 30, so as to prevent the filter particles 41 and the flavoring particles 42 from mixing to affect the filtering effect or the flavoring effect, and provide a guarantee for effectively realizing the filtering effect and the flavoring effect. Illustratively, the barrier 50 is provided with vents (not shown); alternatively, the baffle 50 cooperates with the inner wall of the chamber 30 to form a vent for communicating the space in which the filter particles 41 are located with the space in which the flavor-enhancing particles 42 are located, for example, referring to fig. 6, the baffle 50 cooperates with the cover 2012 to form a vent for communicating the space in which the filter particles 41 are located with the space in which the flavor-enhancing particles 42 are located.

It will be appreciated that the schematic diagram of the filter 200 shown in fig. 3 is merely exemplary, and that the size of the space in which the filter particles 41 are located and the size of the space in which the flavour enhancing particles 42 are located are also merely exemplary, without limiting the structure, shape and/or size of the filter 200. In the actual application process, the method can be changed according to the actual application scene, and the method is not limited.

In some embodiments, the length of the shortest heat exchange path of the aerosol and the flavour enhancing particles 42 is greater than the length of the shortest heat exchange path of the aerosol and the filter particles 41, so that the flavouring path of the aerosol is longer and the flavouring effect is significant. It will be appreciated that as the aerosol flows through the flavour-enhancing particles 42, the aerosol will exchange heat with the flavour-enhancing particles 42, and the path of the heat exchange between the aerosol and the flavour-enhancing particles 42 is the path of the aerosol flowing through the initially contacted flavour-enhancing particles 42 to the end contacted flavour-enhancing particles 42. The heat exchange path of the aerosol and the flavour-enhancing particles 42 comprises at least one, such that the aerosol is allowed to exchange heat through different heat exchange paths to enhance the heat exchange effect. The shortest heat exchange path of the aerosol and the flavour enhancing particles 42 is the one of the heat exchange paths of the aerosol and the flavour enhancing particles 42 that has the smallest length.

Similarly, when the aerosol flows through the filter particles 41, the aerosol can exchange heat with the filter particles 41, and the heat exchange path between the aerosol and the filter particles 41 is the path between the filter particles 41 in initial contact and the filter particles 41 in final contact. The heat exchange path of the aerosol and the filter particles 41 comprises at least one, which enables the aerosol to exchange heat through different heat exchange paths to enhance the heat exchange effect. The shortest heat exchange path of the aerosol and the filter particles 41 is the shortest one of the heat exchange paths of the aerosol and the filter particles 41.

Illustratively, the dashed arrows in fig. 3 represent the general flow direction of the aerosol.

In some embodiments, the temperature change Δt1 of the aerosol before and after passing through the filter particles 41 and the temperature change Δt2 of the aerosol before and after passing through the flavour enhancing particles 42 satisfy: Δt1+.2Δt2, such as Δt1 equaling 2Δt2 or 3Δt2, etc. Since the filter particles 41 are close to the air inlet 10 relative to the flavor-enhancing particles 42 in the flow direction of the aerosol, the temperature of the aerosol close to the air inlet 10 is relatively high, and Δt1 is larger than or equal to 2Δt2, so that a guarantee can be provided for the aerosol flowing out of the air outlet 20 without scalding the mouth.

Illustratively, the length of the shortest heat exchange path of the aerosol and the flavour enhancing particles 42 is greater than the length of the shortest heat exchange path of the aerosol and the filter particles 41, Δt1+.2Δt2. It will be appreciated that although the filtering path (such as the shortest heat exchanging path between the aerosol and the filter particles 41) is short, the temperature drop is large, mainly because the high temperature aerosol contacts the filter particles 41 first, and the temperature difference between the filter particles 41 and the high temperature aerosol is large, so that the heat exchanging between the aerosol and the filter particles 41 is obvious, and the aerosol can be greatly cooled after the heat exchanging between the aerosol and the filter particles 41. When the aerosol flows through the fragrancing particles 42, the temperature difference between the aerosol and the fragrancing particles 42 is small, and thus the heat exchange amplitude between the aerosol and the fragrancing particles 42 is also small.

Applicants found that the temperature of the aerosol is too high, which tends to burn the filter 200; the temperature of the aerosol is too low and the aroma released by the flavour enhancing particles 42 into the aerosol is not noticeable when the aerosol flows through the flavour enhancing particles 42. To this end, in some embodiments, the temperature T0 of the aerosol at the air inlet 10 satisfies: 280 ℃ or more, T0 or more, 50 ℃, such as 50 ℃, 200 ℃, 280 ℃, or any other suitable temperature between 50 ℃ and 280 ℃. In this manner, the flavour enhancing particles 42 can be caused to release sufficient flavour enhancing material to the aerosol as it flows through the flavour enhancing particles 42 for effective flavouring and can prevent scorching of the filter 200. Illustratively, the temperature T0 of the aerosol at the air inlet 10 satisfies: 280℃or more and T0 or more and 200℃or more, such as 200℃250℃280℃or any other suitable temperature between 200℃and 280 ℃.

Referring to fig. 6, the filter 200 is illustratively formed with a vent 205, the vent 205 being in communication with the air inlet 10, the vent 205 being in communication with the chamber 30, air flow from the air inlet 10 into the filter 200 flowing into the chamber 30 through the vent 205. In some embodiments, the temperature T3 of the aerosol at the vent 205 satisfies: 100 ℃ or more, T3 or more, 80 ℃ or more, such as 80 ℃, 90 ℃,100 ℃, or any other suitable temperature between 80 ℃ and 100 ℃. In this manner, the flavour enhancing particles 42 can be caused to release sufficient flavour enhancing material to the aerosol as it flows through the flavour enhancing particles 42 for effective flavouring and can prevent scorching of the filter 200.

Referring to fig. 6, illustratively, the temperature T4 of the aerosol at the top position E of the filter particles 41 satisfies: 55 ℃ or more, T4 or more, 35 ℃ or more, such as 35 ℃, 45 ℃, 55 ℃, or any other suitable temperature between 35 ℃ and 55 ℃. In this way, the flavour enhancing particles 42 can release sufficient flavour enhancing substances to the aerosol when the aerosol flows through the flavour enhancing particles 42 to provide effective flavouring, and the aerosol flowing from the air outlet 20 can be prevented from scalding the user.

Referring to fig. 6, illustratively, the temperature T5 of the aerosol at the top position F of the flavour enhancing particles 42 satisfies: 50 ℃ or more, T5 or more, 35 ℃ or more, such as 35 ℃, 40 ℃, 50 ℃ or any other suitable temperature between 35 ℃ and 50 ℃. In this way, the flavour enhancing particles 42 can release sufficient flavour enhancing substances to the aerosol when the aerosol flows through the flavour enhancing particles 42 to provide effective flavouring, and the aerosol flowing from the air outlet 20 can be prevented from scalding the user.

Referring to fig. 6, illustratively, the temperature T6 of the aerosol at the air outlet 20 satisfies: 48 ℃ or more T6 or more 35 ℃, such as 35 ℃, 40 ℃, 48 ℃, or any other suitable temperature between 35 ℃ and 48 ℃. In this way, the aerosol flowing out from the air outlet 20 can be prevented from scalding the user.

In some embodiments, a portion of the solid particles 40 are porous plant particles and the flavoring substance is a flavor essential oil. The plant particles adopt a porous structure, so that the plant particles are light in weight on one hand and can adsorb the flavor enhancing substances on the other hand. Some of the solid particles 40 are porous plant particles which can enhance the taste of the plant itself and regulate the mouthfeel of the aerosol.

The adsorption quantity of the porous plant particles is too low, so that the utilization rate of the internal space of the porous plant particles is not high; the adsorption quantity of the porous plant particles is too high, so that the problem of liquid leakage is easily caused by liquid. To this end, in some embodiments, the adsorption amount L of the porous plant particles satisfies: and the L is more than or equal to 70 percent and is more than or equal to 30 percent, such as 30 percent, 50 percent, 70 percent or any other suitable value between 30 percent and 70 percent, so that the utilization rate of the inner space of the porous plant particles is fully utilized, and the problem of liquid leakage is prevented.

Illustratively, the flavour enhancing substances include propylene glycol or tobacco flavour and the like. The propylene glycol is used as a solvent of the tobacco essence, and the components of the tobacco essence conform to national food safety standard GB2760, tobacco industry standard YC/T164-2012 and 797 license lists of the tobacco essence, so that the redundant description is omitted herein.
