Example 1
As shown in fig. 1, the filter device of the present invention comprises: a filter body and an aerosol-generating article holder 8 disposed at a distal lip end (i.e., a lower end in fig. 1) of the filter body and extending axially downward. The aerosol-generating article holder 8 comprises two axially extending circular arc segments. Two claws 7 with barbs are arranged on the inner wall of each circular arc piece.
An axial airflow channel 2 is arranged in the filter device main body.
The filter device body includes: a proximal lip filter segment 3 and a distal lip filter segment 6 removably connected. The detachable connection mode can be selected from a threaded connection, a clamping connection and the like. In this embodiment a threaded connection.
Wherein the distal lip filter segment 6 has a tapered cavity 9 communicating with the axial airflow passage 2, the tapered cavity 9 having a larger inner diameter the closer it is to the claw 7. In this embodiment, the tapered cavity 9 is a truncated cone structure. The inner diameter of the upper end of the tapered cavity 9 is equal to the inner diameter of the axial gas flow channel 2.
The filter device body is internally provided with a filler cavity 4 communicated with the axial airflow channel 2 and used for filling a filtering component or a flavoring component. In this embodiment, the filler cavity 4 is filled with filter cotton for adsorbing the perfume. The inner diameter of the filling chamber 4 is larger than the inner diameter of the axial gas flow channel 2. The upper part of the filler cavity 4 is located in said near lip filter segment 3 and the lower part of the filler cavity 4 is located in the far lip filter segment 6. After the proximal lip filter segment 3 and the distal lip filter segment 6 are connected, the joint of the two forms the filler cavity 4. The longitudinal cross-section of the filler chamber 4 is substantially octagonal.
In this embodiment, the outer wall of the near-lip filter segment 3 is substantially a rounded curve. The longitudinal section of 3 outer walls of the near lip filter segments is two symmetrical concave curves, so that a user can conveniently suck the upper end of the near lip filter segments 3 into the mouth, and meanwhile, two concave handheld parts are formed on the outer walls of the main bodies of the filter devices, and the filter devices are convenient for the user to hold.
The outer wall of the distal lip filter segment 6 is substantially linear in longitudinal cross-section to conform to the inner cavity of the aerosol generating device 11. The distal lip segment 6 outer diameter is less than the maximum outer diameter of the proximal lip segment 3. The outer diameter enlargement 5 is the largest outer diameter of the lip-proximal filter segment 3. The outer diameter expansion section 5 is positioned at the far lip end of the near lip filter section 3. One function of the outer diameter expansion section 5 is: when the filter device is used with a side-intake aerosol generating device (such as the aerosol generating device disclosed in application number 201280070578.3, the side intake specifically refers to air intake in a gap between the housing of the aerosol generating device and the heating cavity), the lower end part of the outer diameter expansion section 5 abuts against the upper end part of the housing of the aerosol generating device to block an air flow channel, so that the function of isolating oxygen from the aerosol generating products in the heating cavity is achieved, the heating temperature of the heating cavity can be increased without worrying about the combustion of the aerosol generating products, and the aerosol generated by the aerosol generating products through pyrolysis at a higher temperature is more sufficient.
Of course, in alternative embodiments, an outer flange may be provided on the outer wall of the filter body, which outer flange, as well as the outer diameter expansion segment 5, may close off the air flow path between the aerosol generating device housing and the heating chamber.
The near lip section of the near lip filter tip section is a gradually-expanding cavity 1 communicated with the axial airflow channel. The divergent cavity 1 is capable of emitting and softening the smoke so that the smoke entering the lips of the user is soft and even.

The outer shell of the aerosol generating device 11 is abutted against the lower end part of the outer diameter expanding section 5, and the inflow of the outside air to the heating cavity 11-1 is isolated. Even if a gap exists between the shell of the aerosol generating device 11 and the heating cavity 11-1, the gap is blocked by the outer diameter expansion section 5 and cannot be communicated with the outside air to play a role in air intake.
In alternative embodiments, the aerosol generating device 11 may of course employ other forms of heating, for example electrical resistance heating of the central or circumferential type.
In alternative embodiments, the outer shell of the aerosol-generating device 11 and the lower end of the outer diameter-expanded section 5 may be magnetically connected or inserted.
Of course, in alternative embodiments, the tapered cavity 9 and the filler chamber 4 may be replaced by a single integral cavity having an internal diameter greater than the axial airflow passage communication 2, optionally filled with a reinforcing member such as a filter or bead.
In this embodiment, the aerosol-generating article 10 is simply a smoking segment.
