The injected air will form bubbles in the water. The generation of bubbles helps to disperse the harmful substances and particulate matter in the smoke more effectively in the water, making it easier to be absorbed and processed by water, thereby improving the dissolution and removal efficiency of the harmful substances and particulate matter in the smoke.

[0014] (2) The present invention sets a wetting device so that the rotating rod, connecting rod, brush roller, filter cartridge, U-shaped shell, L-shaped plate, and U-shaped cotton rod cooperate to drive the brush roller to wet the mesh surface of the filter cartridge. The wetted mesh surface of the filter cartridge can improve the efficiency of capturing particulate matter, thereby better adsorbing particulate matter and pollutants in the smoke, thereby improving the purification effect of the smoke; at the same time, the U-shaped shell, the convex plate, the round block, and the brush roller cooperate to drive the convex plate to squeeze one side of the U-shaped cotton rod, and the water adsorbed by the U-shaped cotton rod is squeezed out and sprinkled on the outside of the brush roller. The water sprinkled on the brush roller can help clean the surface of the brush roller, thereby avoiding the problem that particulate matter on the mesh surface of the filter cartridge adheres to the surface of the brush roller, resulting in the brush roller causing secondary pollution to the mesh surface of the filter cartridge when rotating.

[0015] (3) The present invention sets a brushing device so that the rotating rod, the elastic telescopic rod and the fixed plate cooperate to drive the brush to brush the inner wall of the filter cartridge, so that the brush can effectively remove particulate matter attached to the inner wall of the filter cartridge, thereby preventing the filter cartridge from being blocked and maintaining its normal working state; at the same time, the elastic telescopic rod, the fixed plate, the resistance rod, the resistance block and the filter cartridge cooperate to push the fixed plate to drive the brush toward the inner wall of the filter cartridge. The proximity of the brush to the inner wall of the filter cartridge increases the brushing pressure applied to the filter cartridge, making the brush clean the filter cartridge more thoroughly. At the same time, the mesh surface of the filter cartridge will disrupt the bristles of the brush. After the bristles of the brush are disrupted, an irregular brush surface will be formed, which can make the bristles of the brush contact the mesh surface of the filter cartridge more effectively and help remove particulate matter on the mesh surface of the filter cartridge.

Through the setting of the above structure, the Z-shaped tube 210 squeezes the folding capsule 212, and the air in the folding capsule 212 is injected into the water in the water tank ring box 21 through the Z-shaped tube 210. The injected air will form bubbles in the water. The generation of bubbles helps to disperse the harmful substances and particulate matter in the smoke more effectively in the water, making it easier to be absorbed and processed by water, thereby improving the dissolution and removal efficiency of the harmful substances and particulate matter in the smoke.

[0028] The wetting device 3 includes a connecting rod 31, a brush roller 32, a U-shaped shell 33, an L-shaped plate 34, and a U-shaped cotton rod 35. The connecting rod 31 is fixed to the upper outer wall of the rotating rod 24, and the brush roller 32 is rotatably installed at the bottom of one end of the connecting rod 31 away from the rotating rod 24. The rotating shaft of the brush roller 32 passes through the bottom of the rotating ring 23, and the brush roller 32 contacts the outer wall of the filter cartridge 8. The U-shaped shell 33 is slidably installed on the outer wall of the filter cartridge 8, and the U-shaped shell 33 is located outside the brush roller 32. The L-shaped plate 34 is fixed to the side of the U-shaped shell 33 away from the brush roller 32. One end of the U-shaped cotton rod 35 is fixed to The U-shaped cotton rod 35 is arranged on the outer wall of the L-shaped plate 34, and one end of the U-shaped cotton rod 35 extends to the inside of the water tank ring box 21, and the other end of the U-shaped cotton rod 35 contacts the outer wall of the brush roller 32. Through the arrangement of the above structure, the U-shaped cotton rod 35 can absorb the water in the water tank ring box 21 to wet the brush roller 32, so that when the brush roller 32 rotates outside the filter cartridge 8, the brush roller 32 will wet the mesh surface of the filter cartridge 8. The moistened mesh surface of the filter cartridge 8 can improve the capture efficiency of particulate matter, thereby better absorbing the particulate matter and pollutants in the smoke, thereby improving the purification effect of the smoke.

[0029] The wetting device 3 also includes a plurality of round blocks 36 and a protrusion plate 37. The protrusion plate 37 is slidably installed inside the U-shaped shell 33, and the protrusion plate 37 contacts the inner wall of one side of the U-shaped cotton rod 35 close to the brush roller 32. The plurality of round blocks 36 are evenly fixed on the top edge of the fixed cylinder 6. A semi-arc block is fixed on the bottom of the protrusion plate 37. The round blocks 36 are located on the movement trajectory of the semi-arc block of the protrusion plate 37. Through the arrangement of the above structure, the water absorbed by the U-shaped cotton rod 35 is squeezed out and sprinkled on the outside of the brush roller 32. The water sprinkled on the brush roller 32 can help clean the surface of the brush roller 32, thereby avoiding the particulate matter on the mesh surface of the filter cartridge 8 adhering to the surface of the brush roller 32, resulting in the problem of secondary pollution of the mesh surface of the filter cartridge 8 caused by the brush roller 32 when rotating.

[0030] When in use, the bottom opening of the mounting shell 1 is connected to the fire duct by bolts. When the fire duct is exhausting smoke, the suction fan 5 is started, and the suction fan 5 guides the smoke in the fire duct upward. When the smoke passes through the filter cartridge 8, the filter cartridge 8 will filter the particulate matter in the smoke. Then the smoke will be guided by the rotating ring 23 and the L-shaped air guide ring 22. The rotating ring 23 and the L-shaped air guide ring 22 will discharge the smoke into the water of the water tank ring box 21. The water in the water tank ring box 21 can effectively absorb and remove harmful substances and particulate matter in the smoke, thereby achieving the purpose of purifying and discharging smoke, thereby reducing the adverse effect of the filtered and discharged smoke on the air quality; at the same time, during the rotation of the suction fan 5, the rotating rod 24 will be driven to rotate, and the rotating rod 24 will drive the L-shaped rod 27 to rotate. The L-shaped rod 27 drives the ring plate 26 to rotate inside the cavity ring 25. At the same time, the L-shaped rod 27 drives the folding bag 212 and the Z-shaped tube 210 to rotate. 10 drives the slide column 211 to slide along the wavy groove of the wavy groove ring 29. Under the restriction of the wavy groove of the wavy groove ring 29, the wavy groove of the wavy groove ring 29 drives the slide column 211 to move up and down, and the slide column 211 drives the Z-shaped tube 210 to move up and down. Each time the Z-shaped tube 210 moves upward, the Z-shaped tube 210 squeezes the folding bag 212, and the air in the folding bag 212 is injected into the water in the water tank ring box 21 through the Z-shaped tube 210. The injected air will form bubbles in the water. The generation of bubbles helps to disperse the harmful substances and particulate matter in the smoke more effectively in the water, making it easier to be absorbed and processed by water, thereby improving the dissolution and removal efficiency of the harmful substances and particulate matter in the smoke. Each time the Z-shaped tube 210 moves downward, the Z-shaped tube 210 stretches the folding bag 212. At this time, the folding bag 212 can be inhaled from the one-way air inlet nozzle 28 through the cavity of the L-shaped rod 27 and the cavity ring 25.

[0031] During the rotation of the rotating rod 24, the connecting rod 31 is driven to rotate, and the connecting rod 31 drives the brush roller 32 to rotate outside the filter cartridge 8, and the brush roller 32 drives the U-shaped shell 33 and the L-shaped plate 34 to rotate accordingly. Since one end of the U-shaped cotton rod 35 extends into the water tank ring box 21, the U-shaped cotton rod 35 absorbs water in the water tank ring box 21 to wet the brush roller 32, so that during the rotation of the brush roller 32 outside the filter cartridge 8, the brush roller 32 will wet the mesh surface of the filter cartridge 8. The wet mesh surface of the filter cartridge 8 can improve the capture efficiency of particulate matter, thereby better absorbing particulate matter and pollutants in the smoke, thereby improving the purification effect of the smoke; at the same time, the U-shaped shell 33 drives the protrusion plate 37 to rotate, and when the protrusion plate 37 moves to the round block 36, the round block 36 pushes The semi-arc block of the movable protrusion plate 37 drives the protrusion plate 37 to move along the inside of the U-shaped shell 33 toward the brush roller 32, and the protrusion plate 37 squeezes one side of the U-shaped cotton rod 35. The water adsorbed by the U-shaped cotton rod 35 is squeezed out and sprinkled on the outside of the brush roller 32. The water sprinkled on the brush roller 32 can help clean the surface of the brush roller 32, thereby avoiding the problem that particulate matter on the mesh surface of the filter cartridge 8 adheres to the surface of the brush roller 32, causing the brush roller 32 to cause secondary pollution to the mesh surface of the filter cartridge 8 when it rotates. Here, the connecting rod 31 drives the brush roller 32 to rotate, and the brush roller 32 drives the swivel 23 to rotate. Since the L-shaped air guide ring 22 is fixed to the bottom of the inner wall of the water tank ring box 21, the L-shaped air guide ring 22 will not rotate during the operation of the swivel 23.

[0032] See also Figure 1 - Figure 8 On the basis of the above embodiment, in another embodiment of the present invention, a brushing device 4 is provided inside the filter cartridge 8 .

A plurality of brushes 43 are respectively fixed to the side of the two fixed plates 42 away from each other, and the brushes 43 are in contact with the inner wall of the filter cartridge 8. Through the arrangement of the above structure, the brushes 43 will brush the inner wall of the filter cartridge 8, so that the brushes 43 can effectively remove particulate matter attached to the inner wall of the filter cartridge 8, thereby preventing the filter cartridge 8 from being blocked and maintaining its normal working state.

[0034] The brushing device 4 also includes two resistance rods 44 and a plurality of resistance blocks 45. The two resistance rods 44 are respectively fixed on the sides of the two fixed plates 42 close to each other. The side of the resistance rod 44 away from the fixed plate 42 is semicircular. The plurality of resistance blocks 45 are evenly fixed on the top of the conical ring 7. The side of the resistance block 45 away from the center of the conical ring 7 is semicircular.

Through the arrangement of the above structure , so that the resistance rod 44 pushes the fixing plate 42 to drive the brush 43 toward the inner wall of the filter cartridge 8. The proximity of the brush 43 to the inner wall of the filter cartridge 8 will increase the brushing pressure applied to the filter cartridge 8, making the brush 43 clean the filter cartridge 8 more thoroughly. At the same time, the mesh surface of the filter cartridge 8 will disrupt the bristles of the brush 43. After the bristles of the brush 43 are disrupted, an irregular brush surface will be formed, which can make the bristles of the brush 43 more effectively contact the mesh surface of the filter cartridge 8, thereby helping to remove particulate matter on the mesh surface of the filter cartridge 8.

[0035] When in use, when the rotating rod 24 rotates, the elastic telescopic rod 41 is driven to rotate, and the elastic telescopic rod 41 drives the brush 43 to rotate through the fixing plate 42, and the brush 43 brushes the inner wall of the filter cartridge 8, so that the brush 43 can effectively remove the particles attached to the inner wall of the filter cartridge 8, thereby preventing the filter cartridge 8 from being blocked and maintaining its normal working state; at the same time, the elastic telescopic rod 41 drives the resistance rod 44 to rotate through the fixing plate 42, and when the semicircular shape of the resistance rod 44 rotates to the semicircular position of the resistance block 45, the semicircular shape of the resistance block 45 pushes the semicircular shape of the resistance rod 44 to drive the resistance The rod 44 moves toward the inner wall of the filter cartridge 8, and the resistance rod 44 pushes the fixed plate 42 to drive the brush 43 toward the inner wall of the filter cartridge 8. At the same time, the fixed plate 42 drives the telescopic end of the elastic telescopic rod 41 to stretch. The brush 43 approaches the inner wall of the filter cartridge 8, which increases the brushing pressure applied to the filter cartridge 8, making the brush 43 clean the filter cartridge 8 more thoroughly. At the same time, the mesh surface of the filter cartridge 8 will disrupt the bristles of the brush 43. After the bristles of the brush 43 are disrupted, an irregular brush surface will be formed, which can make the bristles of the brush 43 more effectively contact the mesh surface of the filter cartridge 8, thereby helping to remove particulate matter on the mesh surface of the filter cartridge 8.
