A cigarette plug adapter 3 is provided at the lower end of the cigarette holder portion 1. A filter cavity 101 is provided in the cigarette holder portion 1. The filter cavity 101 is filled with a flavor filler 4. A secondary filter cotton 5 and a primary filter cotton 6 are respectively provided at the upper and lower ends of the flavor filler 4. An upper anti-permeability membrane assembly 7 and a lower anti-permeability membrane assembly 8 are respectively provided at the ends of the secondary filter cotton 5 and the primary filter cotton 6 away from the flavor filler 4.

[0024] See attached Figure 1-3 The smoke barrel portion 1 and the cigarette holder portion 2 are an integrally formed structure and the connection between the cigarette holder portion 2 and the smoke barrel portion 1 is transitioned through an arc chamfer. An installation guide portion 102 is provided on the outer wall of the smoke barrel portion 1, and a limit ring 103 is also provided on the outer wall of the smoke barrel portion 1 close to the cigarette holder portion 2. The cigarette plug adapter head 3 at the lower end of the smoke barrel portion 1 is inserted downward into the assembly port of the heat-not-burn tobacco device through the installation guide portion 102, and is clamped with the inner wall of the assembly port until the position of the limit ring 103 is reached to achieve installation in place. A clamping block 104 matching the cigarette plug adapter head 3 is also provided at the lower end of the smoke barrel portion 1, and the cigarette plug adapter head 3 is embedded in the clamping block 104.

[0025] See attached Figure 1-3 The mouthpiece 2 has a smoke outlet channel 201, which is connected to the filter chamber 101. A step one is formed between the smoke outlet channel 201 and the filter chamber 101, and a step two is formed between the cigarette adapter 3 and the filter chamber 101. The upper anti-permeability membrane component 7 and the lower anti-permeability membrane component 8 are respectively embedded in the step one and the step two. The upper anti-permeability membrane component 7, the secondary filter cotton 5, the flavor filler 4, the primary filter cotton 6, and the lower anti-permeability membrane component 8 are arranged in the filter chamber 101 from top to bottom. The upper and lower ends are fixed by the upper anti-permeability membrane component 7 and the lower anti-permeability membrane component 8 of the embedded structure to limit the secondary filter cotton 5, the flavor filler 4, and the primary filter cotton 6 between the two.

[0026] See attached Figure 1-3The upper anti-permeation membrane assembly 7 and the lower anti-permeation membrane assembly 8 have the same structure. The lower anti-permeation membrane assembly 8 includes a positioning clamp ring 801 and an anti-permeation membrane 802. The anti-permeation membrane 802 is embedded in the filter cavity 101 of the smoke pipe 1 at both ends through the structural design of the positioning clamp ring 801. The anti-permeation membrane 802 is made of TPU membrane material. The material of the anti-permeation membrane 802 used in this technical solution can also be polytetrafluoroethylene (PTFE) membrane, GORE-TEX, hydrophilic polymer non-porous film, etc. The upper There is a certain gap between the anti-permeability membrane component 7 and the secondary filter cotton 5, and between the lower anti-permeability membrane component 8 and the primary filter cotton 6. The upper anti-permeability membrane component 7 and the lower anti-permeability membrane component 8 have a microporous structure to achieve the function of waterproof and breathable. The waterproof and breathable properties of the upper anti-permeability membrane component 7 and the lower anti-permeability membrane component 8 are utilized to prevent the water vapor generated after the smoke passes through from entering the chimney part 1 and condensing into condensed water and condensed smoke oil, thereby preventing reflux, affecting the life of the smoking device and the smoking taste of the filter cigarette holder.

[0027] See attached Figure 1-3 There is no gap between the secondary filter cotton 5, the primary filter cotton 6 and the flavor filler 4. There are multiple smoke impact holes in the secondary filter cotton 5 and the primary filter cotton 6. The smoke impact holes are micropores that are connected front to back. The smoke impact holes in the secondary filter cotton 5 and the smoke impact holes in the primary filter cotton 6 are axially offset. Through physical jet and wall attachment effects, the smoke changes its speed through the microporous smoke impact holes to form liquid. During the smoke circulation process, a certain degree of tar, nicotine and carbon monoxide in the smoke are filtered out through the primary filter cotton 6 and the secondary filter cotton 5. The three major harmful substances marked on the cigarette box can be effectively filtered, which not only retains the original taste of the cigarette, but also does not affect the taste, reducing the harm of harmful substances to the human body.

[0028] See attached Figure 1-3 A cigarette insertion port 301 is provided on the cigarette insertion adapter head 3. The cigarette insertion port 301 is a through hole with a gradually expanding lower end. The gradually expanding design increases the bottom space to facilitate the insertion of cigarette butts. The cigarette insertion adapter head 3 also has mounting protrusions 302 on both sides that match the smoke barrel part 1. The cigarette insertion adapter head 3 is embedded in the block 104. The cigarette insertion port 301 corresponds to the filter cavity 101 in the smoke barrel part 1 and is connected thereto. In the present technical solution, the cigarette insertion adapter head 3 with cigarette insertion ports 301 of different calibers can be replaced corresponding to thin cigarettes, medium cigarettes, and thick cigarettes. The cigarette insertion adapter head 3 is made of high temperature resistant material.

[0029] See attached Figure 1-3 The flavor filler 4 is a porous material and is located between the upper anti-permeation membrane component 7 and the lower anti-permeation membrane component 8. The flavor filler 4 releases aromas of different flavors when heated and enters the mainstream smoke. It has good aroma retention and good sustained release performance, thereby improving the sensory quality of cigarette smoking.

[0030] The cigarette butt insertion filter cigarette holder provided in this embodiment is used in conjunction with the heat-not-burn tobacco device. Different from the traditional filter tip insertion type, the present technical solution adopts the cigarette butt insertion type. When in use, one end of the cigarette holder is inserted into the heat-not-burn tobacco device, and the exposed cigarette butt end is inserted from the cigarette insertion port 301 of the cigarette adapter head 3. When inhaling, the cigarette is heated by the tobacco device to generate smoke. The smoke passes through the lower anti-permeability membrane component 8, the primary filter cotton 6, the flavor filler 4, the secondary filter cotton 5 and the upper anti-permeability membrane component 7 in sequence, and a certain degree of tar, nicotine, carbon monoxide and other harmful substances in the smoke are filtered out, and then sucked out from the cigarette holder part 2. During the inhalation process, the water vapor generated after the smoke is filtered is isolated in the filter cavity 101 through the upper anti-permeability membrane component 7 and the lower anti-permeability membrane component 8, so as to avoid the condensed water generated after the condensation of the water vapor and the condensed tobacco oil from flowing back into the tobacco device, so as to prevent affecting the heating effect of the tobacco device and the smoking taste of the cigarette holder.

[0031] To sum up, the technical effect achieved by the present technical scheme is: different from the traditional filter tip insertion type, the present technical scheme adopts the cigarette butt insertion type, and the condensed water and condensed tobacco oil generated after inhalation are isolated in the tobacco pipe by adopting the upper anti-permeability membrane assembly and the lower anti-permeability membrane assembly arranged up and down in the smoke pipe, so as to prevent the condensed water and condensed tobacco oil from flowing back into the smoking device, thereby affecting the life of the smoking device, and by adopting a replaceable cigarette plug adapter head, it can adapt to thin cigarettes, medium cigarettes and thick cigarettes of different calibers, and has strong applicability.
