[0039] The following is a detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

[0040] Refer to Figures 1 to 10 , the present invention provides a rotatable cigarette clamping mechanism, including: an exhaust rear housing 1, a cigarette clamping nozzle 2, a lock cover 3, a clamping jaw disc 4 and a front cover 5. For the convenience of understanding, Figure 3The front cover 5 on the right side shown is in the front position, and the exhaust rear housing 1 on the front and left side is in the rear position. The exhaust rear housing 1 is not limited to a cylindrical shape, and its front side is recessed inward to form a receiving cavity 101. In other words, the exhaust rear housing 1 is a groove cavity structure with a closed rear end and an open front end. An air suction port 102 leading to the receiving cavity 101 is provided along the central axis on the rear outer wall of the exhaust rear housing 1, and this air suction port 102 is used for directly smoking or installing a suction nozzle for smoking. The cigarette holder 2 is installed in the receiving cavity 101, and a cigarette positioning hole 201 is provided in the middle of the cigarette holder 2, and the cigarette positioning hole 201 communicates with the air suction port 102.

[0041] Furthermore, the locking cover 3 is fixed in the receiving cavity 101 and presses the cigarette holder 2. The clamping claw disc 4 is installed on the locking cover 3. The clamping claw disc 4 has an annular claw disc body 401. A plurality of clamping claws 402 extend radially toward the central axis along the inner circle of the claw disc body 401. The plurality of clamping claws 402 are evenly distributed in an annular shape at equal intervals, and the plurality of clamping claws 402 can all undergo elastic deformation. The inner ends of the plurality of clamping claws 402 are all at a certain distance from the center of the clamping claw disc 4. Furthermore, a first central hole 403 formed by surrounding the inner ends of the plurality of clamping claws 402 is used for the cigarette to pass through. The front cover 5 and the locking cover 3 cooperate with each other to clamp and fix the clamping claw disc 4.

[0042] Among them, a third central hole is provided in the middle of the front cover 5, a fourth central hole is provided in the middle of the locking cover 3, the first central hole 403, the third central hole, the fourth central hole and the cigarette positioning hole 201 are all coaxially distributed. The cigarette is inserted from the third central hole of the front cover 5 along its filter tip end, and sequentially passes through the first central hole 403 of the clamping claw disc 4 and the fourth central hole of the locking cover 3 and is inserted into the cigarette positioning hole 201.

[0043] In this application, both the cigarette holder 2 and the clamping claw disc 4 are made of soft rubber material, preferably silicone, which is non-toxic and harmless to the human body, and can increase the fitting degree between the filter tip end of the cigarette and the cigarette positioning hole 201, and prevent air leakage from causing poor smoking effect. It should be noted that the diameter of the first central hole 403 of the clamping claw disc 4 is smaller than the diameter of the cigarette. In this way, when the cigarette passes through the first central hole 403, it will cause the plurality of clamping claws 402 to undergo elastic deformation, expand the first central hole 403, and at the same time, the inner ends of the plurality of clamping claws 402 all abut against the outer circumferential surface of the cigarette, thereby clamping the cigarette, and cooperating with the cigarette positioning hole 201 to form a stable clamping of the cigarette and it is not easy to fall off.

[0044] Refer to Figure 3 and Figure 5, the diameter of the cigarette positioning hole 201 expands step by step from one end close to the suction port 102 towards the other end, thereby forming positioning slots with different diameters for cigarettes with corresponding diameters to be inserted. It can adapt to cigarettes with different diameters, and cigarettes with different diameters can form a good fit with the corresponding positioning slots, ensuring airtightness between them. At the same time, the adjacent two positioning slots are connected by a conical transition surface, which is beneficial for the cigarette to be smoothly inserted into the corresponding positioning slot.

First card slots 5013 are provided on the inner side surfaces of the hook portions 5012, and four first bumps 302 are annularly and equally spaced on the rear side surface of the lock cover 3 facing away from the front cover 5. The four first bumps 302 respectively fall into the corresponding four first card slots 5013, thereby realizing the fixation between the front cover 5 and the lock cover 3.

[0050] Refer to Figure 3 , Figure 4 , Figure 6 and Figure 8 , a plurality of second card slots 303 are provided at intervals around the edge of the front side surface of the lock cover 3 facing the front cover 5. Specifically, a plurality of avoidance holes 301 divide the outer ring of the lock cover 3 into a plurality of arc-shaped fixing pieces, and the second card slots 303 are respectively provided on the fixing pieces one by one. A plurality of second bumps 103 are provided along the inner wall of the circumference of the exhaust rear shell 1, and the second bumps 103 fall into the corresponding second card slots 303. And under the mutual cooperation of the second bumps 103 and the second card slots 303, the lock cover 3 cannot rotate in the exhaust rear shell 1. In addition, the inner wall of the circumference of the exhaust rear shell 1 at the rear side of the lock cover 3 is thickened to form a limiting step 104, and the limiting step 104 is used to stop the lock cover 3, and cooperate with the second bumps 103 to form a limit on the lock cover 3, thereby realizing the fixation between the lock cover 3 and the exhaust rear shell 1.

[0051] Refer to Figure 3 , Figure 7 and Figure 8 , positioning boss structures for mutual cooperation are provided on the opposite side surfaces of the lock cover 3 and the clamping jaw disc 4. Specifically, a third annular boss is provided on the front side surface of the lock cover 3, and a plurality of notches are equally spaced on the third annular boss to form a plurality of first positioning bosses 305. The outer periphery of the claw disc main body 401 at the front side extends outward to form a second flange 404, and a plurality of second positioning bosses 405 are provided between the rear side of the second flange 404 and the outer peripheral surface of the claw disc main body 401. The plurality of second positioning bosses 405 respectively fall into the notches one by one, coincide with the first positioning bosses 305, and make the second flange 404 abut against the side surface of the first positioning boss 305, thereby realizing the positioning of the clamping jaw disc 4.
