The inlet and outlet are preferably microporous structures. The filter cavity of the filter 230 is filled with at least one filter material, such as activated carbon, filter cotton, etc., so that the filter 230 can filter and purify the flue gas flowing through the filter material; the front end of the thinning columnar body 240 is in contact with the rear end surface of the support ring 260, and the outer wall of the thinning columnar body 240 is provided with a plurality of axially conductive thinning grooves 241 for the front and rear ends at circumferential intervals (preferably uniform intervals), and the plurality of thinning grooves 241 are connected to the inner surface of the second channel. The walls cooperate to form a number of thinning channels, and the thinning columnar body 240 can divert the smoke to the various thinning channels of the outer wall and guide it through, so that the smoke will impact the end face of the thinning columnar body 240 when flowing through the thinning columnar body 240, so that the harmful substances in the smoke will condense and stay on the thinning columnar body 240 to achieve a purification effect. At the same time, the large smoke can be divided into multiple small smoke streams through the thinning channel to improve the subsequent filtering and purification effect; the front end of the spiral columnar body 250 abuts against the thinning channel The rear end face of the columnar body 240 and the outer wall of the spiral columnar body 250 are provided with a spiral groove 251. The spiral groove 251 cooperates with the inner wall of the second channel to form a spiral channel connected to the refinement channel. In this way, the smoke passing through the refinement channel will impact the groove wall of the spiral groove 251 so that the harmful substances condense and remain on the spiral columnar body 250. At the same time, the spiral groove 251 on the spiral columnar body 250 also effectively extends the flow path of the smoke, thereby achieving better filtering and purification effects.

[0050] In the above scheme, if Figure 3 and Figure 5 As shown, a support ring 260 is further provided between the filter 230 and the thinning columnar body 240. The filter 230, the support ring 260, the thinning columnar body 240 and the spiral columnar body 250 are sequentially abutted and connected and clamped between the front wall of the front mounting portion and the rear wall of the rear mounting portion; the front end of the support ring 260 abuts against the rear end face of the filter 230 and circles the outlet on the filter 230, and the front end of the thinning columnar body 240 abuts against the rear end face of the support ring 260 The front end of the refined groove 241 thereon is located within the annular surface of the support ring 260, and the front end surface of the refined columnar body 240 is provided with at least one connecting groove 242 for connecting to the annular hole of the support ring 260 corresponding to each refined groove 241. Such an arrangement not only facilitates the control of the connecting cross-sectional area between the connecting groove 242 and the annular hole of the support ring 260, but also avoids the direct connection between the flue gas flowing in the flue gas channel and the refined groove 241, thereby effectively improving the filtering and purification effect.

[0051] In the above scheme, if Figure 5 As shown, the spiral columnar body 250 is preferably a hollow tubular structure, and the rear end portion of the spiral columnar body 250 is provided with at least one connecting gap 252 that communicates with the notch of the spiral groove 251. In this way, when the spiral columnar body 250 is pressed against the rear wall of the rear mounting portion, the smoke flowing along the spiral groove 251 can pass through the connecting gap 252 to facilitate flowing into the second channel at the rear.

[0052] In this embodiment, if Figure 1 and Figure 3 As shown, the bite 200 is provided with an oxygen-enriched hole 221 connected to the thinning channel or the spiral channel. The oxygen-enriched hole 221 can effectively increase the amount of oxygen inhaled during smoking, thereby reducing the formation of carbon monoxide.

[0053] Compared with the existing technology, the utility model has a simple and reasonable structure and has the following advantages:

[0054] 1. The cigarette holder and the mouthpiece are connected by magnetic attraction, which not only facilitates the disassembly and assembly between the two and makes the disassembly and assembly process more playable and interesting, but also effectively ensures the stability of the cooperation between the two.

[0055] 2. The cigarette holder adopts a split two-section structure, which effectively shortens the length of a single section of the cigarette holder for easy storage and carrying. At the same time, the two sections of the cigarette holder can be easily assembled and connected through a connecting tube and a pressure cap for use. Furthermore, the assembled cigarette holder structure can be used to insert cigarettes of large, medium and small calibers, which greatly expands its scope of application.

[0056] 3. The filter assembly of the bite is a multi-filter structure consisting of a filter, a support ring, a refined columnar body and a spiral columnar body, which can more effectively remove harmful substances in the inhaled smoke, thereby effectively reducing the damage caused by smoking to the human body;

[0057] 4. The design of oxygen-enriched holes can effectively increase the intake of oxygen and reduce the formation of carbon monoxide.

[0058] The above disclosure is only an embodiment of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
