Then, under the action of the right spring 1312, the right latch tooth 1311 is reset after being squeezed, and is meshed with the gear 134 again. When the gear 134 rotates clockwise and is driven, the guide plate 1317 provided on the sliding plate 137 moves along with the sliding plate 137, and the auxiliary rod 1319 sliding in the guide groove 1318 drives the control plate 15 to move under the action of the auxiliary plate 1320 and the connecting plate, so that the control plate 15 is in contact with the inner wall of the connecting pipe 93 and slides on the inner wall of the contact plate, thereby blocking the lower through hole 96 and preventing air from entering the second auxiliary pipe 97.

[0062] When the plurality of filter holes 4 in the filter plate 3 are blocked, the air between the filter plate 3 and the collecting plate 111 cannot be quickly discharged through the filter holes 4, and the airflow generated by the air pump 91 accumulates in the tank body 1 and the connecting pipe 93, which will cause the airflow in the connecting pipe 93 to be unable to quickly enter the tank body 1, thereby slowing down the airflow speed in the connecting pipe 93, thereby affecting the rotation of the control fan group 133. When the control fan group 133 cannot rely on the airflow to rotate clockwise, the spring 141 starts to exert force, and the spring 141 will make the control shaft 131 rotate counterclockwise. The needle rotates, thereby causing the gear 134 on the outside of the control shaft 131 to rotate counterclockwise with it. When the gear 134 rotates counterclockwise, the gear 134 will drive the right latch 1311 meshing with it to move, and the right latch 1311 will mesh with multiple control latches 138, thereby driving the sliding plate 137 and the left latch 1315 to move, so that the sliding plate 137 slides in the connecting tube 93 through the limiting plate 136 at its bottom. When the end of the limiting plate 136 close to the right latch 1311 is completely fitted with one end of the limiting groove 135, the gears 134 will rotate counterclockwise. The wheel 134 will continue to push the left latch tooth 1315, and under the action of the gear 134, the left latch tooth 1315 will slide on both sides of the sliding plate 137 through the left slide bars 1313 on both sides, so that the left latch tooth 1315 and the gear 134 are temporarily out of meshing state. When the left latch tooth 1315 is no longer in contact with the gear 134, the left spring 1316 will push the left latch tooth 1315 to contact and mesh with the gear 134 again, so that the left latch tooth 1315 always remains in meshing state with the gear 134, and the sliding plate 137 rotates the gear 134 counterclockwise. Under the action of 34, the control groove blocks the upper through hole 94 through the guide plate 1317 and the auxiliary rod 1319, so that the airflow cannot enter the first auxiliary pipe 95 through the upper through hole 94. Its function is to switch the direction of the airflow through the flow rate of the airflow in the tank body 1 and the connecting pipe 93, so that the airflow switching movement direction has different effects. When the airflow speed is faster, the control board 15 will not move. When the airflow speed slows down, the control board 15 will automatically move under the influence of the control fan blade group 133 and switch to the blocking state.

[0063] The reset member 14 includes a clockwork spring 141 arranged at one end of the control shaft 131 away from the control fan blade group 133, and the end of the clockwork spring 141 away from the control shaft 131 is arranged in the connecting tube 93. When the control shaft 131 rotates clockwise, the clockwise rotating control shaft 131 will cause the clockwork spring 141 to start storing force. When the control fan blade group 133 cannot rotate clockwise by relying on the airflow, the clockwork spring 141 starts to exert force, and the clockwork spring 141 will cause the control shaft 131 to rotate counterclockwise. Its function is to store force through the clockwise rotation of the control shaft 131, and when the control fan blade group 133 cannot rotate clockwise by the airflow, it starts to exert force and drives the control shaft 131 to rotate counterclockwise, so that when the airflow in the connecting tube 93 cannot quickly enter the tank body 1, it provides power for the rotation of the control plate 15 and the switching of the airflow movement direction.

[0064] During use, when the staff needs to control air pollution, they start the air pump 91. At this time, the air pump 91 will suck in the air outside the tank body 1 and discharge it into the connecting pipe 93 through the driving pipe 92 at its output end. When the gas enters the connecting pipe 93, the flowing gas will blow the control fan blade group 133, causing the control fan blade group 133 to rotate and enter the corresponding first auxiliary pipe 95 or second auxiliary pipe 97 through the upper through hole 94 or the lower through hole 96. After the airflow passes through the second auxiliary pipe 97 and the one-way valve 98 into the tank body 1, the one-way valve 98 will immediately close to prevent the airflow in the tank body 1 from flowing back.

[0065] When the gas in the driving tube 92 blows the control blade group 133, the control blade group 133 will rotate clockwise, thereby driving the control shaft 131 at its axis to rotate together. At this time, the clockwise rotating control shaft 131 will cause the spring spring 141 to start accumulating force. When the control shaft 131 rotates clockwise, the gear 134 set on the outside of the control shaft 131 will rotate clockwise along with the control shaft 131, thereby driving the sliding plate through the multiple control teeth 138 engaged therewith. 137 moves. When the sliding plate 137 moves under the action of the clockwise rotating gear 134 and the plurality of control teeth 138, the limit plate 136 at the bottom of the sliding plate 137 will slide in the limit groove 135 in the connecting pipe 93. The limit groove 135 and the limit plate 136 will limit the running track of the sliding plate 137 so that the sliding plate 137 can only move in the specified area. When the gear 134 rotates clockwise and engages with the right tooth 1311, the gear 134 will continue to rotate, but At this time, one end of the limiting plate 136 has completely fit with one end of the limiting groove 135, so that the right latch tooth 1311 is squeezed toward the sliding plate 137. When the right latch tooth 1311 is squeezed by the gear 134, the right slide bars 139 on both sides of the right latch tooth 1311 slide on both sides of the sliding plate 137, so that the right latch tooth 1311 is temporarily displaced. Then, under the action of the right spring 1312, the right latch tooth 1311 is reset after being squeezed, and is meshed with the gear 134 again. When the gear 134 rotates clockwise and is driven, the guide plate 1317 provided on the sliding plate 137 moves along with the sliding plate 137, and the auxiliary rod 1319 sliding in the guide groove 1318 drives the control plate 15 to move under the action of the auxiliary plate 1320 and the connecting plate, so that the control plate 15 is in contact with the inner wall of the connecting pipe 93 and slides on the inner wall of the contact plate, thereby blocking the lower through hole 96 and preventing air from entering the second auxiliary pipe 97.

[0066] When the plurality of filter holes 4 in the filter plate 3 are blocked, the air between the filter plate 3 and the collecting plate 111 cannot be quickly discharged through the filter holes 4, and the air flow generated by the air pump 91 accumulates in the tank body 1 and the connecting pipe 93, which will cause the air flow in the connecting pipe 93 to be unable to quickly enter the tank body 1, thereby slowing down the air flow rate in the connecting pipe 93, thereby affecting the rotation of the control fan blade group 133. When the control fan blade group 133 cannot rely on the air flow to rotate clockwise, the spring 141 starts to exert force, and the spring 141 will cause the control shaft 131 to rotate counterclockwise, thereby causing the gear 134 on the outside of the control shaft 131 to rotate counterclockwise with it. When the gear 134 rotates counterclockwise, the gear 134 will drive the right latch 1311 meshing with it to move, and through the right latch 1311 meshing with the plurality of control latch teeth 138, it will drive the sliding plate 137 and the left latch tooth 1315 to move, so that the sliding plate 137 When the gear 134 is rotated counterclockwise, the sliding plate 137 blocks the control slot from the upper through hole 94 through the guide plate 1317 and the auxiliary rod 1319, so that the air flow cannot pass through the upper through hole 94 and enter the first auxiliary pipe 95;

[0067] When the control plate 15 blocks the lower through hole 96 and the airflow enters the first auxiliary pipe 95 through the upper through hole 94, the moving airflow pushes the first blade group 103. After being impacted by the airflow, the first blade group 103 drives the transmission rod 101 at its axis to rotate together. When the transmission rod 101 rotates, the scraper 5 provided on the top of the transmission rod 101 rotates along with the transmission rod 101 and cleans the bottom of the filter plate 3, so that the debris adsorbed on the bottom of the filter plate 3 is scraped off by the scraper 5. The bearing 102 provided on the outside of the transmission rod 101 can reduce the friction between the transmission rod 101 and the filter plate 3, so that the first blade group 103 and the second blade group 104 on the outside of the transmission rod 101 are more easily driven by the airflow.

[0068] When the control plate 15 blocks the upper through hole 94 and the airflow enters the second auxiliary pipe 97 through the lower through hole 96, the moving airflow pushes the second fan blade group 104. After being impacted by the airflow, the second fan blade group 104 will drive the transmission rod 101 at its axis to move together, so that no matter whether the upper through hole 94 or the lower through hole 96 is blocked, the transmission rod 101 can always keep rotating, without affecting the normal rotation of the scraper 5 and the spray plate 6. After the airflow passes through the one-way valve 98 in the second auxiliary pipe 97, the one-way valve 98 will close after the airflow passes, preventing the gas in the tank body 1 below the collecting plate 111 from flowing back.

[0069] When the airflow enters the tank body 1 below the collecting plate 111 through the second auxiliary pipe 97, the one-way valve 98 will restrict the backflow of the gas after the gas passes through. The gas below the collecting plate 111 will occupy the space in the tank body 1 and squeeze the water flow in the tank body 1, so that the water flows through the drainage hole 122 into the drainage pipe, and then the water flows through the drainage pipe to reach the spray plate 6 and sprays water mist through the spray plate 6, so that the water mist can clean the filter hole 4. When water needs to be replenished, unscrew the water inlet cap 124 and pour the water to be replenished into the water inlet pipe 123. The blocking airbag 125 slidably arranged on the outside of the transmission rod 101 can promptly block the drainage hole 122 after the water is used up, so as to prevent the airflow from being discharged from the drainage hole 122 and causing air pressure leakage.

[0070] After the scraper 5 or the spray plate 6 cleans the filter plate 3 and the filter holes 4, the debris and sewage will fall onto the collecting plate 111 and then enter the U-shaped tube 113. The dustproof plate 112 arranged on the collecting plate 111 can prevent the debris in the filter plate 3 and the filter holes 4 from entering the bottom of the collecting plate 111. When the atmospheric pollution control is completed and the debris needs to be discharged, the sewage discharge handle 115 is unscrewed to make the debris in the U-shaped tube 113 flow out through the sewage discharge pipe 114, thereby completing the debris collection work. The U-shaped plate can prevent sewage from flowing back, and the sewage discharge handle 115 can keep the air pressure in the tank body 1 from being discharged through other channels, so that the air flow and pressure drive the switching of the control panel 15 to be more stable.

[0071] Example 2: Please refer to Figure 1-4 , the present invention provides a technical solution:

[0072] The collecting plate 111 is an arcuate surface, and the U-shaped tube 113 is arranged at the lowest point of the collecting plate 111. When debris and sewage fall on the collecting plate 111, the arcuate collecting plate 111 can quickly collect the debris and sewage falling on its surface, and the fluid sewage can quickly gather to the lowest point of the collecting plate 111 and enter the U-shaped tube 113 in time. Its function is to quickly collect sewage and debris and prevent the debris from being blown away by the incoming airflow.
