The utility model provides a filter element still includes cylindric parcel layer, and this parcel layer cladding is in the filter segment outside, and closely laminates with the at least partial lateral surface of above-mentioned each grade baffle, and then forms airflow channel by the clearance passageway in each grade baffle.
It is noted that the end of the filter element adjacent to the mouth of the consumer is referred to as the proximal end (i.e., end B in fig. 1), and is generally used for the consumer to draw filtered smoke from the filter element through the mouth, and the end of the filter element further away from the mouth of the consumer is referred to as the distal end (i.e., end a in fig. 1), and is generally in communication with a smoke generating device (e.g., a cigarette cartridge in a cigarette or an e-cigarette) for receiving unfiltered smoke for filtering.
For example, on the outer side of the filter segment 1 shown in fig. 1, there are multiple stages of baffles distributed from the far mouth end (a end) to the near mouth end (B end), and referring to fig. 3, an axial view of the filter segment 1 is shown, and the multiple stages of baffles specifically include a first stage baffle 103, a second stage baffle 104, a third stage baffle 105, a fourth stage baffle 106, a fifth stage baffle 107, and a sixth stage baffle 108, which are arranged in parallel with each other. Further, on each stage of baffle, there are 4 clearance channels, see fig. 2, which shows a radial view of the filter segment 1 on the side of the a end, wherein the first stage of baffle 103 is taken as an example and comprises a channel a, a channel b, a channel c and a channel d.

Wherein, the wherein one end of a plurality of protruding separation blades that each grade baffle included closely laminates to the main part of filter segment, and one end closely laminates to the inner chamber on cylindric parcel layer in addition to clearance passageway between a plurality of protruding separation blades of baffle at the same level and the clearance space between the different grades of baffles and formation flue gas passageway
As shown in fig. 1, each stage of baffle may comprise a plurality of raised baffles which are arranged at the same axial position in the filter segment 1 and are not arranged continuously around the axial center line of the filter segment, but form one or more intermittent portions as clearance passages by arranging a plurality of raised baffles circumferentially apart from each other in the filter segment. For example, as shown in fig. 1 and fig. 2, taking the primary baffle 103 as an example, the primary baffle 103 includes a plurality of raised baffles in a fan-shaped structure, and outer side surfaces of the plurality of raised baffles are located on the same circular ring, so as to form a plurality of clearance passages including a passage a, a passage b, a passage c, and a passage d.
Preferably, the height of the raised blocking piece is between 0.2 mm and 5mm, further preferably between 0.5 mm and 2mm, the thickness of the raised blocking piece is preferably between 0.1 mm and 2mm, and the width of a gap between any two adjacent raised blocking pieces in the plurality of raised blocking pieces is between 0.1 mm and 3mm, so that the suction resistance of the filtering component can be reduced.
Alternatively, each stage of the baffle plates may be an annular structure fixedly sleeved outside the main body part of the filter section (i.e. the part of the cylindrical filter section except for the plurality of stages of the baffle plates), and at least one through hole is arranged on each stage of the baffle plates to form a gap channel. Optionally, the inner ring side of the ring structure of each stage of baffle is closely attached to the outer side of the main body part of the cylindrical filter segment, and the outer ring side of the ring structure of each stage of baffle is closely attached to the inner cavity of the cylindrical wrapping layer, so that a flue gas channel is formed by a gap channel formed in each stage of baffle and a gap space between different stages of baffles.

Preferably, the filter segment is made of a polymer material as a matrix, wherein the polymer material comprises one or more of the following: acetate tow, polypropylene tow and polylactic acid. The polymer material is a material commonly used in the cigarette industry, and has low cost and easy acquisition.
Preferably, the wrapping layer is formed as a paper fiber product, and a surface of the wrapping layer is formed to include a plurality of micro-through holes. The paper fiber product is a material commonly used in the cigarette industry, is low in cost and easy to obtain, and promotes the exchange efficiency of heat exchange of smoke with the outside through the wrapping layer by arranging the plurality of micro through holes on the surface of the wrapping layer, further reduces the smoke temperature, and promotes the smoking taste of consumers.
