Specifically, the recycling circulation assembly 7 includes a recycling tank 29, a recycling tank 27, a liquid discharge pipeline 28, a second water pump 46, a circulation pipeline 44 and a suction pipeline 45, the recycling tank 29 is disposed at the top of the base 2, the recycling tank 27 is disposed at the bottom of the exhaust pipeline 11, a rectangular through groove for the recycling tank 27 to pass through is formed in the bottom of the exhaust pipeline 11, the recycling tank 29 is communicated with the recycling tank 27 through the liquid discharge pipeline 28, the second water pump 46 is disposed at the top of the recycling tank 29, an input end of the second water pump 46 is communicated with the recycling tank 29 through the suction pipeline 45, an output end of the second water pump 46 is communicated with the water storage tank 10 through the circulation pipeline 44, and a waste liquid pipeline 17 is disposed at the bottom of the recycling tank 29; the purified liquid flows into the recovery tank 29 through the recovery tank 27, and is conveyed to the water storage tank 10 through the second water pump 46, so that the purified liquid can be recycled.

Specifically, the bottom of the inner wall of the water storage tank 10 is provided with a heater 41, the bottom of the motor mounting rack 33 is provided with a sewage discharge pipeline 49, the top of the water storage tank 10 is provided with an air pump 43, and the output end of the air pump 43 is communicated with the inside of the water storage tank 10; the heater 41 is used for heating the purified liquid in the water storage tank 10, the residual waste liquid flows out through the sewage discharge pipeline 49 during cleaning, and the air pump 43 is used for pressurizing the water storage tank 10, so that the atomization effect of the purified liquid and the flushing pressure during cleaning are improved.

The working principle is as follows: waterproof motor 50 works, drives exhaust fan 18 and rotates, and exhaust fan 18 is with in the oil smoke suction exhaust duct 11, and the oil smoke is when through filter screen 34, and large granule thing in the oil smoke is tentatively purified, and air pump 43 pressurizes storage water tank 10, and later the solenoid valve is opened, and the scavenging solution after being diluted passes through atomizing pipe 30 and enters into atomizer 31, and remaining oil smoke is behind the scavenging solution after the atomizing, is discharged in the atmosphere through exhaust duct 11 after being purified completely.

Driving motor 42 work, it rotates to drive mounting panel 9, mounting panel 9 continues to drive the terminal two sets of dwang 39 rotations of mounting panel 9, because every group dwang 39 all rotates with mounting panel 9 to be connected, and the top of every group dwang 39 all overlaps and is equipped with a set of driven gear 36, thereby realized the revolution to puddler 40, driven gear 36 meshes with driving gear 37 again, driving gear 37 is through two sets of dead lever 38 and storage water tank 10 fixed connection, and then make two sets of puddler 40 realize the rotation in the revolution, thereby realized to the intensive mixing with the purifying liquid.

The screw rod sliding table 53 works to drive the shielding plate 47 to move upwards to seal and separate the public exhaust pipeline 11 from the filter screen 34, so that the cleaned water flow is prevented from flowing backwards into the public exhaust pipeline 1, then the heater 41 heats the purified liquid in the water tank, the air pump 43 pressurizes the water storage tank 10, and then the high-temperature and high-pressure purified liquid thoroughly washes the filter screen 34 and the exhaust fan 18 through the high-pressure nozzle 26.
