[0005] In addition, there is a certain risk when replacing the activated carbon filter screen. The activated carbon filter screen adsorbs a large amount of impurities during use, and if it is bumped during replacement, the impurities on the filter screen can easily leak out, causing secondary pollution.

[0047] The particle adhering mechanism 200 comprises two rotating seats 210 fixedly connected with the top wall and the bottom wall of the box 110, a round rod 211 rotatably connected to the outer wall of the rotating seat 210, a rocker 212 fixed to one end of one of the round rods 211, a group of square grooves 230 provided on the inner wall of one side of the square groove 2 112, an arc-shaped frame 232 slidably inserted into the square groove 3 230, a spring 231 fixed between the outer wall of the arc-shaped frame 232 and the inner wall of the square groove 3 230, and a protrusion 233 fixed to the outer wall of one of the arc-shaped frames 232. The thin film 240 can be conveniently rolled and replaced in part when it adheres to more particles by shaking the rocker 212 by a person, and the operation is simple and fast.
[0048] The leakage-proof replacing mechanism 300 comprises an activated carbon net frame 310 inserted into the square groove 1 111, a protrusion 311 fixed to one end of the top of the activated carbon net frame 310, a group of L-shaped frames 1 320 fixedly connected to the outer wall of the box 110 at the square groove 1 111, an L-shaped frame 2 330 inserted into the square groove 1 111, a group of L-shaped grooves 1 331 provided on the outer wall of the L-shaped frame 2 330, a group of L-shaped grooves 2 342 provided on the outer walls of the two ends of a square shell 340, a square groove 4 341 provided on the top wall of the square shell 340, and two handles 343 fixed to the outer walls of the two sides of the square shell 340. The activated carbon net frame 310 is completely encapsulated in the square shell 340 for operation when it is replaced, and the leakage of impurities on the activated carbon net frame 310 is effectively prevented by the leakage-proof replacing mechanism 300.
[0049] Specifically, in operation, the fan 120 is driven to guide the exhaust gas into the box body 110 through the air inlet of the box body 110, and the filter screen frame 130 close to the fan 120 starts to play a role to preliminarily filter most of the particles in the exhaust gas. An inclined angle is arranged at the rear of the filter screen frame 130 in the box body 110, and the local area of the film 240 is located at this position. The exhaust gas is blown onto the film 240 wound between the two pipe coils 241, and the film 240 is coated with a polyvinyl butyral PVB coating. When the exhaust gas contacts the coating, due to the viscosity of the PVB coating, the fine particles can be adhered. This design utilizes the adsorption characteristics of the PVB coating to fine particles, effectively solving the problem that ordinary filter screens are difficult to intercept fine particles. When the film 240 inside the box body 110 adheres more particles, the person can push the protruding block one 233 to drive the arc-shaped frame 232 at the top of the box body 110 to slide into the square groove three 230, thereby releasing the limiting of the film 240 above the box body 110. Then the person uses the rocker 212 to rotate the round rod 211 at the top of the box body 110. The rotation of the round rod 211 drives the pipe coil 241 inserted thereon to rotate, thereby winding the used part of the film 240, so that the unused area of the film 240 enters the inside of the box body 110 to continue to adhere particles. When the film 240 needs to be replaced and cleaned as a whole, the person detaches the T-shaped frame 220 from one end of the square groove two 112 on the box body 110, separates the rotating seat two 221 from one end of the round rod 211, and then removes the pipe coil 241 at the bottom and top of the box body 110 from the round rod 211, thereby completing the overall replacement of the film 240. When the person needs to replace the activated carbon screen frame 310, the L-shaped frame two 330 is first pushed upward to separate the L-shaped groove one 331 on the L-shaped frame two 330 from the L-shaped frame one 320, thereby unsealing. At this time, the activated carbon screen frame 310 inside the box body 110 can be seen from the square groove one 111, the square shell 340 is lifted by holding the handle 343, the L-shaped groove two 342 on the square shell 340 is inserted along the L-shaped frame one 320, the protruding block two 311 is pushed to drive the activated carbon screen frame 310 to slide along the track of the square groove one 111 into the square shell 340, and the protruding block two 311 is slidably inserted into the square groove four 341. After the activated carbon screen frame 310 is installed into the square shell 340, the square shell 340 is lifted by holding the handle 343 and separated from the L-shaped frame one 320, thereby completing the disassembly of the activated carbon screen frame 310, and effectively preventing impurities from leaking out of the activated carbon screen frame 310 during replacement to cause secondary pollution.
