In this embodiment, adsorption and dust removal subassembly 7 includes driven shaft 71 and sliding shaft 72, driven shaft 71 rotates with three 33 of support of three-way pipe 3 to be connected, it is connected with rotating ring 74 to rotate through one-way bearing 73 on the driven shaft 71, the circumference equidistance is equipped with four spliced poles 741 on the rotating ring 74, spliced pole 741 outside threaded connection has sleeve 75, sliding connection has slider 721 in the sleeve 75, the one end and the slider 721 of sliding shaft 72 are connected, and its other end passes sleeve 75 and is connected with brush 722, the cover is equipped with spring two 76 on the sliding shaft 72 between slider 721 and the sleeve 75, the bottom just is located the outside of brush 722 and is equipped with friction ring 77 in outer tube 1, friction ring 77 realizes fixedly through pressing from both sides between support and outer tube 1. The brush 722 and the friction ring 77 are made of different materials, and when the brush 722 and the friction ring 77 rub against each other, an electrostatic effect is generated, so that dust is adsorbed onto the friction ring 77.

In this embodiment, cleaning device 4 includes pivot 40, the one end of pivot 40 is rotated with a support 21 and is connected, and filter screen 20 is worn to the other end to sliding connection is in driven shaft 71, and passes through spline structure and driven shaft 71 transmission moment of torsion, fixedly connected with flabellum 41 in the pivot 40, the upside of filter screen 20 is equipped with triangle brush one 42, and its downside is equipped with triangle brush two 43, all be connected through one-way bearing two between triangle brush one 42 and the pivot 40 and between triangle brush two 43 and the driven shaft 71.

In this embodiment, when the airflow in the filter tube 2 is upward, the rotating shaft 40 rotates forward, the second one-way bearing is not locked, the first triangular brush 42 and the second triangular brush 43 are kept stationary, the first one-way bearing 73 is locked, and the rotating ring 74 rotates, whereas when the airflow in the filter tube 2 is downward, the rotating shaft 40 rotates backward, the second one-way bearing and the third one-way bearing are locked, the first triangular brush 42 and the second triangular brush 43 rotate, the first one-way bearing 73 is not locked, and the rotating ring 74 is kept stationary.

The working process and the principle thereof are as follows:

when the air compressor 8 works, the contact switch 5 is in a closed state, and the controller controls the first electromagnetic valve 61 to be in a normally open state and the second electromagnetic valve 62 to be in a normally closed state.

The air is sucked from the air inlet 31 of the three-way pipe 3, the first one-way air valve 311 is pushed by the wind to be opened inwards, the second one-way air valve 321 is kept closed, then the upward air flow passes through the filter screen 20, dust is filtered and intercepted, the air flow continues upwards, the fan blade 41 is pushed to rotate forwards when meeting the fan blade 41, the fan blade 41 drives the rotating shaft 40 to rotate forwards, the second one-way bearing is in an unlocked state at the moment, namely, the first triangular brush 42 and the rotating shaft 40 and the second triangular brush 43 and the driven shaft 71 are both in rotating connection, and therefore the first triangular brush 42 and the second triangular brush 43 cannot rotate along with the rotating shaft 40.

The rotating shaft 40 drives the driven shaft 71 to rotate forward, and a section of the bottom of the rotating shaft 40 is of a spline structure with a non-circular section, so that the driven shaft 71 can slide in the driven shaft and transmit torque. At this time, the first one-way bearing 73 is in a locked state, the driven shaft 71 rotates to drive the rotating ring 74 to rotate, so that the sliding shaft 72 in the sleeve 75 generates an outward centrifugal force, the sliding shaft 72 slides outward, the sliding block 721 compresses the second spring 76, the brush 722 is in contact with the friction ring 77, the brush 722 keeps a fixed direction to rub against the friction ring 77 along with the rotation of the rotating ring 74, static electricity is generated on the friction ring 77, and dust is adsorbed onto the friction ring 77 when air with dust passes through the friction ring 77.

When the dust on the filter screen 20 is accumulated more and more, the original air can pass through the filter screen 20, but after the filter screen 20 is blocked, the filter pipe 2 at this moment is equivalent to a piston, and the negative pressure above the filter pipe 2 can suck the filter pipe 2 for a certain distance, so that the sliding column 211 is contacted with the contact switch 5, and the contact switch 5 is triggered to be conducted.

The controller receives the conducting signal, the first electromagnetic valve 61 is controlled to be closed, the second electromagnetic valve 62 is opened, high-pressure gas stored in the gas tank in the air compressor 8 enters from the top of the outer pipe 1 to form downward airflow, the airflow is in contact with the fan blades 41 to drive the fan blades 41 to rotate reversely, the first triangular brush 42 and the second triangular brush 43 are driven to rotate, and therefore the filter screen 20 is cleaned, and cleaned dust is blown to the three-way pipe 3 in cooperation with the reverse airflow.

At this moment, the first one-way air valve 311 is closed, the second one-way air valve 321 is opened, the air with dust passes through the friction ring 77, and because the first one-way bearing 73 is in an unlocked state, although the driven shaft 71 rotates, the rotating ring 74 stops rotating, the brush 722 is not in contact with the friction ring 77 any more, static electricity is gradually weakened and reduced, the dust adsorbed on the friction ring 77 falls off, and the cleaned dust is collected and processed along with the blowing of the first air flow from the discharge port 32 to the dust collecting gauze bag 322, so that the dust overflow is avoided.

It will be appreciated by those skilled in the art that the invention can be embodied in other specific forms without departing from the spirit or essential attributes thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or range of equivalency of the invention are to be embraced within their scope.
