arranged by the four braking universal wheels 27, the pump 15, the exhaust fan 3 and the electromagnetic valve 21 are operated by the operation control panel 22, when the exhaust fan 3 is operated, the exhaust fan 3 extracts the gas with particles outside, as one end surface of the exhaust tube 205 is smaller and smaller by the tube mouth size of the other end surface, the space for the gas with particles to move is smaller and smaller, when the gas enters the connecting tube 204, under the action of the pressure and the exhaust fan 3, the flow velocity of the gas with particles flowing through the connecting tube 204 is enhanced, the gas with particles enters the inside of the top tube 203 in a high-speed flowing manner, as the opening size from one end surface of the top tube 203 to the other end surface is larger and larger, the gas with particles flowing at high speed is under the action of the pressure, slowing down the movement speed, larger dust particles and the stone particles sucked into the dust removing shell 2 along with the gas with the particles can be separated from the gas under the action of gravity, the solid slides down along the inner side wall of the inner lower part of the top cylinder 203, then the solid is discharged out of the dust removing shell 2 through the first discharge pipe 12 and enters the first collecting box 10 to be collected in a concentrated manner, meanwhile, under the action of inertia, the gas with the particles collides with a plurality of baffle plates 6, so that impurities or dust particles in the gas with the particles can be collided with the baffle plates 6 to realize secondary separation of the solid and the gas, under the action of the collision force, the baffle plates 6 drive the ring plate 5 to overturn on the transmission rod 4, the separated impurities or dust particles can fall into gaps between the baffle plates 6 and ceaselessly overturn along with the baffle plates 6, when the gaps overturn to the lower part, under the action of gravity, the impurities or dust particles in the gaps can fall onto the inner side wall of the inner lower part of the middle cylinder 202 and the top cylinder 203, finally, the gas with particles after secondary filtration continues to move towards the other end face of the middle cylinder 202, the gas with particles can be filtered for the third time under the action of the filter screen 7, if the gas also contains large particles of dust or impurities, the gas is retained by the filter screen 7, and finally the gas is discharged out of the interior of the dust-removing shell 2 through the first discharge pipe 12 and enters the interior of the first collection box 10, the air passing through the filter screen 7 collides with the inner side wall of the bottom cylinder 201, if the air also contains dust or impurities during collision, the dust or impurities can be separated from the air for the fourth time, the dust or impurities can slowly slide down along the inner side wall of the bottom cylinder 201 under the action of gravity, and then the gas is discharged out of the interior of the dust-removing shell 2 through the second discharge cylinder, when the pump 15 and the electromagnetic valve 21 work, under the action of the pump 15, the water source in the water tank 14 enters the fixed pipe 19 after passing through the output pipe 17 and the input pipe 18 in sequence, and is finally sprayed out through the spray head 20, the sprayed water source sprays the air passing through the filter screen 7, so that impurities or dust attached to the air are discharged out of the dust removal shell 2 through the second discharge pipe 13 along with the water source under the action of water source flushing, the fifth separation and dust removal are realized, and the triple effects of cleaning, dust removal and air purification are achieved, the waste liquid mixed with the impurities and dust finally enters the second collection box 11 and is subjected to centralized recovery treatment, so that resource waste is avoided, the hand protection pad 26 is arranged to improve the flexibility of a user when pushing and pulling the handle 25, the comfort of the device during use is enhanced, the first guide plate 23 and the second guide plate 24 both play a role in guiding flow, and small particles in the middle cylinder 202 are avoided, Dust or waste liquid are piled up on the inside wall of well section of thick bamboo 202 below, lead to the inside of a little granule stone, dust or waste liquid can't discharge well section of thick bamboo 202 through first discharging pipe 12 and second discharging pipe 13, influence the result of use of device, and the setting of apron 16 is first can guarantee the inside leakproofness of water tank 14, and second can be convenient for supply the water source to the inside of water tank 14 through dismantling apron 16, the setting of water tank 14 can be convenient for provide the water source for the device, and solenoid valve 21's setting can be convenient for control input tube 18 and whether switch on, the utility model discloses simple structure, convenient operation, the practicality is strong, can use widely.
