Before use, the smoke removal pipe 1 is connected to the smoke outlet of the oil smoke removal equipment, and purified water is injected into the water tank 5 through the water inlet pipe 51. The height of the purified water is lower than the height of the activated carbon filter plate 61 in the water tank 5 (to ensure that there is an oil smoke channel between the activated carbon filter plate 61 and the purified water surface). Finally, the high-pressure water supply pump 71 and the exhaust fan body 3 are connected to the external power supply through a wire. The exhaust fan body 3 draws the oil smoke into the smoke removal pipe 1. The oil smoke is blocked by the sealing partition plate 42 and enters the water tank 5 to be filtered through the activated carbon filter plate 6. At the same time, the high-pressure water supply pump 71 draws the purified water in the water tank 5 into the spray water guide plate 41 for spraying to dilute and purify the oil smoke passing through. The purified gas is finally discharged from the outlet of the smoke removal pipe 1;

[0030] The right surface of the activated carbon filter plate 6 is fixedly mounted with a sealing block 61. The left surfaces of the two sealing blocks 61 are respectively in contact with the right surface of the exhaust fan body 3 and the water storage tank 5. The right surface of the sealing block 61 is fixedly mounted with a handle 62. The sealing block 61 can prevent the leakage of oil smoke.

[0031] The outer surface of the connecting base 2 is symmetrically provided with a receiving groove 21, and a telescopic rod 22 and a spring 23 are fixedly installed in the receiving groove 21. The outer end of the telescopic rod 23 is rotatably installed with a fixed block 25, and the outer surface of the fixed block 25 is fixedly installed with a positioning block 251. The outer end of the spring 23 is fixedly installed with a top plate 24, and the outer surface of the top plate 24 is in contact with the inner surface of the fixed block 25. A positioning arc groove 211 is provided in the receiving groove 21, and a locking groove 33 is symmetrically provided on the outer surface of the exhaust fan body 3 through the inner cavity. A fixed arc groove 331 is provided in the locking groove 33, and a fixed arc groove 331 is provided between the fixed arc groove 331 and the positioning arc groove 211. There is a sliding groove 332 at the beginning, and the inner surface of the fixed arc groove 331 fits with the outer surface of the positioning block 251. When the exhaust fan body 3 needs to be removed, pinch the half ring 252 and rotate the fixing block 25, slide the positioning block 251 in the fixing block 25 into the sliding groove 332, and press the fixing block 25 inward. When the positioning block 251 is located at the connection between the sliding groove 332 and the positioning arc groove 221 (the half ring 252 and the fixing block 25 are both inside the receiving groove 21), rotate the fixing block 25 so that the positioning block 251 slides to the limit position in the positioning arc groove 221. At this time, the exhaust fan body 3 can be removed by lifting it up. When installing the exhaust fan body 3, the reverse operation can be performed;

[0032] A sealing ring 32 is fixedly installed in the inner cavity of the exhaust fan body 3. The lower surface of the sealing ring 32 is in contact with the upper surface of the connecting base 2. The sealing ring 32 can prevent oil smoke leakage.

[0033] The width of the sliding groove 332, the positioning arc groove 211 and the fixed arc groove 331 is the same as the width of the positioning block 251, and the positioning block 25 can slide in the sliding groove 332, the positioning arc groove 211 and the fixed arc groove 331. By sliding and adjusting the positioning block 251 in the sliding groove 332, the positioning arc groove 211 and the fixed arc groove 331, the exhaust fan body 3 can be easily disassembled and assembled.

[0034] A half ring 252 is fixedly mounted on the outer surface of the fixing block 25 to facilitate the rotation of the fixing block 25 .

[0035] Working principle: Before use, connect the smoke removal pipe 1 to the smoke outlet of the oil smoke removal equipment, and inject purified water into the water tank 5 through the water inlet pipe 51. The height of the purified water is lower than the height of the activated carbon filter plate 61 in the water tank 5 (to ensure that there is an oil smoke channel between the activated carbon filter plate 61 and the purified water surface). Finally, connect the high-pressure water supply pump 71 and the exhaust fan body 3 to the external power supply through a wire. The exhaust fan body 3 draws the oil smoke into the smoke removal pipe 1. The oil smoke is blocked by the sealing partition plate 42 and enters the water tank 5 to be filtered through the activated carbon filter plate 6. At the same time, the high-pressure water supply pump 71 draws the purified water in the water tank 5 into the spray water guide plate 41 for spraying to dilute and purify the passing oil smoke. The purified gas is finally discharged from the outlet of the smoke removal pipe 1.

[0036] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
