The guide rod 14 is placed in the through hole 522, and the air on the front and rear sides of the dust filter partition 2 is detected through the pressure difference sensor 13. The change in pressure difference is used to judge the degree of dust accumulation on the upper part of the dust filter partition 2 after a period of use. The accumulation of dust is large, resulting in a large air pressure difference between the front and rear sides of the dust filter partition 2, exceeding the pressure difference. The preset value of the sensor 13 can transmit the signal to the controller 9 for control.

A dust filter partition 2 is inserted into a slot in the middle of the upper side wall of the air intake housing 1. The dust filter partition 2 includes an outer frame 21, and an inner frame of the outer frame 21 is provided with a layer of dust filter cloth 22.

The upper end of the screw rod 3 is rotationally connected to the top of the shell through a fixed sleeve 31. The fixed sleeve 31 at the upper end ensures that the screw rod 3 is rotating. During the process, always maintain an upright position.

The lower end of the screw rod 3 extends out of the bottom of the housing and is fixedly connected to the output shaft of the servo motor 4. By controlling the servo motor 4 to periodically reciprocate counterclockwise, the screw rod 3 drives the vacuum cleaner head 51 to reciprocate up and down.

A dust suction mechanism 5 is installed on the screw rod 3. The dust suction mechanism 5 includes a dust suction head 51. The dust suction head 51 is in the shape of a long rectangle and its width is equal to the width of the dust filter cloth 22. The dust suction head 51 is The opening of the dust head 51 faces the surface of the dust filter cloth 22. The middle part of the front side of the dust head 51 is fixedly connected to a bump 52. A threaded hole 521 is provided in the middle of the bump 52. The right side of the threaded hole 521 A through hole 522 is opened, and the hole on the left side wall of the bump 52 is connected to a dust suction hose 53. The dust suction hose 53 penetrates the bottom of the air intake housing 1. The screw rod 3 rotates to drive the bump 52 together with the rear end. The dust collecting head 51 reciprocates up and down, so that the dust collecting head 51 repeatedly sucks the dust deposited on the surface of the dust filter cloth 22 .

A dust collecting bin 6 is provided at the lower part of the air inlet housing 1. A fixed partition 61 is provided in the dust collecting bin 6. A circle of spray pipes 62 is provided on the side wall of the dust collecting bin under the fixed partition 61. A drawer 63 is provided in the front side wall opening of the lower part of the spray pipe 62, and the fixed partition 61 serves to isolate water vapor to prevent the water mist sprayed from the spray pipe 62 from corroding the upper servo motor 4 and dust pump 7.

The lower end of the dust suction hose 53 is connected to the dust extraction pump 7. The dust extraction pump 7 is installed on the fixed partition 61. The exhaust pipe of the dust extraction pump 7 penetrates downward through the fixed partition. 61. The dust extraction pump 7 sucks away the dust through the dust suction hose 53 and discharges it into the dust collecting bin 6 at the bottom.

One end of the opening of the spray pipe 62 passes through the left side wall of the dust collecting bin 6 and is connected with the ultrasonic humidifier 8. A controller 9 is installed on the right side wall of the dust collecting bin 6, and dust is discharged into the dust collecting bin 6. Within, the controller 9 controls the ultrasonic humidifier 8 to start, spraying the water mist from the spray pipe 62 surrounding the exhaust pipe at the lower end of the dust pump 7, wrapping the dust in all directions, and accelerating its rapid humidification with water. settlement.

The working principle of the utility model: when in use, dusty air enters the air intake housing 1 through the filter 11 on the rear side of the air intake housing 1, and is filtered by the dust filter partition 2 in the air intake housing 1. The dust in the filter cloth 22 accumulates on the dust filter cloth 22. After a period of use, as the dust continues to accumulate, the holes on the dust filter cloth 22 are gradually blocked, which in turn causes the air pressure difference between the front and rear sides of the dust filter cloth 22 to increase. When the dust filter cloth 22 After the pressure difference sensor 14 on the front and rear sides of the cloth 22 detects that the pressure difference value exceeds the preset threshold, the signal is transmitted to the controller 9. The controller 9 controls the servo motor 4 to rotate periodically clockwise and counterclockwise, and at the same time, controls the dust extraction. The pump 7 and the ultrasonic humidifier 8 are turned on, and the dust suction head 51 on the screw rod 3 reciprocates up and down along the guide rod 14 to suck away the dust accumulated on the dust filter cloth 22 and flow into the dust suction pump 7 through the dust suction hose 53 , and then the dust is discharged into the lower dust collecting bin 6 through the dust extraction pump 7. The dust falling into the dust collecting bin 6 quickly settles into the lower drawer 63 due to the water mist sprayed from the surrounding spray pipe 62. , thereby realizing automatic cleaning of dust on the dust filter cloth 22 and at the same time humidifying and settling the dust to prevent dust from spreading again during the collection process and causing secondary pollution.
