The first spring 401 will squeeze the top block 4, the top block 4 will press against the sliding block 203, and when the top block 4 is pressed, the Z-shaped limiting rod 402 will limit the top block 4.

[0027] In this embodiment, a second spring 406 is fixed on one side of the inner walls of the two second vertical grooves 108, and the other ends of the two second springs 406 are respectively fixed to one ends of the two Z-shaped limiting rods 402.

[0028] In this embodiment, two symmetric first baffles 405 are fixed on both sides of the mutually remote sides of the two top blocks 4. Guide blocks 404 are fixed on the mutually remote sides of the two top blocks 4, and the guide blocks 404 are located at one end of the V-shaped groove of the V-shaped limiting block 403.

[0029] In this embodiment, a circular fixing frame 202 is fixed on the outer wall of the filter screen plate 2. Sliding blocks 203 are fixed on both the top and bottom of the circular fixing frame 202, and the sliding blocks 203 are matched with the first vertical groove 106, the horizontal groove 107, and the second vertical groove 108. Two symmetric handles 201 are fixed on the outer wall of one end of the circular fixing frame 202. A smoking mechanism is provided inside the smoking pipe 104.

[0030] In this embodiment, the smoking mechanism includes a same fixing plate 301 fixed on the top and bottom of the inner wall of the smoking pipe 104. One end of the fixing plate 301 is rotatably connected to a rotating rod 303. A suction fan 302 is fixed at one end of the rotating rod 303. A motor 3 is installed at the other end of the fixing plate 301, and the output shaft of the motor 3 is fixedly connected to the other end of the rotating rod 303. The other end of the smoking pipe 104 is fixed with a smoke outlet pipe 105, and the smoke outlet pipe 105 is inclined. A filtering mechanism is provided inside the smoke outlet pipe 105. The suction fan 302 will suck the external smoke into the smoking pipe 104 and then discharge it from the smoke outlet pipe 105.

[0031] In this embodiment, the filtering mechanism includes an adsorption layer 1051 and an activated carbon layer 1052 provided on the inner wall of the smoke outlet pipe 105. The adsorption layer 1051 and the activated carbon layer 1052 will filter the toxic substances in the smoke.

[0033] Working principle: When in use, first, the entire device is displaced to the area where smoke needs to be exhausted through the universal wheels 102. With the smoking mechanism provided, the motor 3 is operated. The motor 3 drives the rotating rod 303 to rotate, and the rotating rod 303 drives the suction fan 302 to rotate. At this time, the suction fan 302 inhales the external smoke into the smoking pipe 104. When the smoke passes through the smoke outlet pipe 105, the adsorption layer 1051 and the activated carbon layer 1052 can adsorb the harmful substances in the smoke and then discharge it from the smoke outlet pipe 105, thus achieving the effect of filtering and discharging the smoke. When filtering and discharging the smoke, the filter mesh plate 2 filters the external impurities to prevent them from adhering to the outer wall of the suction fan 302 and affecting its smoking effect. When it is necessary to disassemble, repair, and maintain the filter mesh plate 2, with the quick-release mechanism provided, by pressing the circular fixing frame 202 with the handle 201, the circular fixing frame 202 drives the sliding block 203 to move. The sliding block 203 squeezes the top block 4, and the top block 4 squeezes the first spring 401. When the top block 4 drives the V-shaped limiting block 403 to move and contact one end of the Z-shaped limiting rod 402, the Z-shaped limiting rod 402 rotates and slides in the V-shaped limiting block 403. When the other end of the Z-shaped limiting rod 402 moves into the V-shaped groove of the V-shaped limiting block 403, the Z-shaped limiting rod 402 limits the top block 4. At this time, rotate the handle 201, and the handle 201 drives the sliding block 203 to move in the horizontal groove 107. When it moves to one end of the first vertical groove 106, pull the handle 201 to open the rotating baffle 109, and then take out the filter mesh plate 2, thus achieving the effect of quickly installing and disassembling the filter mesh plate 2.
