[0013] The beneficial effects of the present invention are:

[0014] 1. The present invention starts the air purifier to drive the filter to rotate, replacing the side of the filter where air enters with the clean side. At the same time, the air purifier drives the brush to move up and down to clean the side of the filter where dust accumulates, thereby realizing automatic cleaning of the filter, avoiding filter blockage, and continuously filtering the air.

[0015] 2. The air purifier will drive the power input shaft and propeller blades to rotate at high speed. Air will enter through the filter, which will filter the dust in the air. The gearbox will reduce the speed provided by the power input shaft and output it through the power output shaft, thereby driving the L-shaped strong magnet to drive the square strong magnet to rotate. When the square strong magnet is reset, it will drive the filter to rotate a quarter of a turn, rotating the filter on the side where the air is entering to the side of the fixed frame, and rotating the clean filter on the side where the air is entering the air filter chamber, so that the filter on the side with dust accumulation is replaced with a clean filter, thereby completing the filter replacement and continuing to filter the air to prevent air from always entering from one side of the filter, causing dust to accumulate on the filter and causing the filter to be blocked.

[0016] 3. In addition, when the square strong magnet rotates, it will push the arc-shaped piston to move, and then drive the hexagonal cross to move upward and get stuck in the slot of the power output shaft. The slow rotation of the power output shaft will drive the power output shaft to rotate, and then drive the brush to move back and forth along the wavy groove of the wave turntable, cleaning the dust accumulated on the filter, thereby preventing the filter from being blocked and allowing the filter to continue to filter the air. Compared with traditional air purifiers, the present invention can realize automatic cleaning of the filter, and there is no need to manually remove the filter for cleaning, which will be more convenient and practical, and easy to use.

[0017] 4. In addition, when the hexagonal cross is reset downward, the air in the straight cylinder will be pushed to the air guide pipe, and then the air will be diverted through the air distributor. The diverted air is evenly blown out from several air outlets on the brush, blowing the dust on the filter and the dust swept off by the brush into the dust collection box, which is convenient for dust collection. At the same time, the dust on the filter can be cleaned more fully and work more efficiently.

[0018] 5. In addition, the rubber sealing strips on both sides of the fixing frame will block the dust, which can effectively prevent the dust swept by the brush from floating around the air filter cavity, thereby limiting the dust in the dust collection box, allowing the dust collection box to collect dust more concentratedly. Then the staff can open the dust collection box to clean the dust, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The filter replacement device 6 includes an L-shaped strong magnet 61, a square strong magnet 62, an arc spring 63, a fixed mounting plate 64, an inclined surface 65, a block 66 and a torsion spring 67. The L-shaped strong magnet 61 is connected to the power output shaft 54 ​​by bolts. The L-shaped strong magnet 61 has an "L"-shaped structure. The square strong magnet 62 is slidably connected to the semicircular groove of the air filter chamber 2. The square strong magnet 62 contacts the L-shaped strong magnet 61. The square strong magnet 62 is located in the filter 4. The fixed mounting plate 64 is welded to the upper side surface inside the air filter chamber 2.

The square strong magnet 62 contacts one of the blocks 66. Two torsion springs 67 are connected between the block 66 and the filter 4 by a hook.

[0039] In actual operation, the staff turns on the air purifier 55. The start of the air purifier 55 will drive the power input shaft 52 to rotate rapidly, and the power input shaft 52 will drive the propeller blades 53 to rotate at high speed. The high-speed rotation of the propeller blades 53 will guide the air, allowing the air to enter from the filter screen 4 on one side of the arc-shaped opening of the air filter chamber 2. The propeller blades 53 will then guide the air to the air purifier 55. The filter screen 4 will filter the dust in the air. The air purifier 55 will purify the air, and the purified air will be discharged through the semicircular filter screen of the air deflector 3. The rapid rotation of the power input shaft 52 will drive the input shaft of the gearbox 51 to rotate, thereby driving the gearbox 51. The gearbox 51 The speed will be slowed down, and the slowed power will be output through the output shaft. The slow rotation of the output shaft of the gearbox 51 will drive the power output shaft 54 ​​to rotate slowly. The rotation of the power output shaft 54 ​​will drive the L-shaped strong magnet 61 to rotate counterclockwise. Since there is a strong magnetic force between the L-shaped strong magnet 61 and the square strong magnet 62, the counterclockwise rotation of the L-shaped strong magnet 61 will drive the movement along the semicircular groove of the air filter chamber 2. The arc spring 63 is compressed. Since the filter screen 4 is provided with an inclined surface 65, the block 66 can swing in one direction. The counterclockwise rotation of the square strong magnet 62 will contact one of the blocks 66 and push the block 66 to swing. The torsion spring 67 is compressed, and the square strong magnet 62 continues to move. It will disengage from one of the blocks 66. When the square strong magnet 62 moves to the end of the semicircular groove of the air filter chamber 2, the air filter chamber 2 will limit the square strong magnet 62. The L-shaped strong magnet 61 continues to rotate and will disengage from the square strong magnet 62. The arc spring 63 resets and drives the square strong magnet 62 to reset. When the square strong magnet 62 resets, it will re-contact one of the blocks 66. Since the filter 4 will limit the block 66, the block 66 will not swing at this time. When the square strong magnet 62 resets, it will drive one of the blocks 66 to move together. The movement of one of the blocks 66 will drive the filter 4 to rotate a quarter of a turn. The filter 4 rotates a quarter of a turn just The filter on the side where air is introduced will be rotated to the side of the fixing frame, and the clean filter on the side where air is introduced into the air filter chamber 2, so that the filter on the side where dust is accumulated is replaced with a clean filter, thereby completing the filter replacement of the filter 4 and continuing to filter the air, preventing air from always entering from one side of the filter 4, causing dust to accumulate on the filter 4 and causing blockage of the filter 4; when the square strong magnet 62 is reset, the L-shaped strong magnet 61 continues to rotate and will re-contact the square strong magnet 62 and continue to drive the square strong magnet 62 to rotate, thereby realizing the continuous replacement of the filter 4 and allowing air to continue to pass in, so that the air purifier 55 can continue to filter the air.

[0040] After the square strong magnet 62 is reset, the staff can push the hexagonal cross 413 to move upward. The upward movement of the hexagonal cross 413 will contact the bottom end of the power output shaft 54 ​​and get stuck in the slot of the power output shaft 54. The slow rotation of the power output shaft 54 ​​will drive the hexagonal cross 413 to rotate slowly. The slow rotation of the hexagonal cross 413 will drive the straight cylinder 412 to rotate. The rotation of the straight cylinder 412 will drive the wave turntable 411 to rotate. The rotation of the wave turntable 411 will drive the brush 414 to move back and forth along the wavy groove of the wave turntable 411. At this time, the filter screen 4 on the side with dust accumulated has been replaced to the side of the fixed frame, and the reciprocating movement of the brush 414 up and down will brush the filter screen 4, removing the dust accumulated on the filter screen 4 The dust is cleaned, thereby preventing the filter 4 from being blocked, so that the filter 4 can continue to filter the air. Compared with the traditional air purifier 55, the present invention can realize automatic cleaning of the filter 4, and there is no need to manually remove the filter for cleaning, which is more convenient and practical and easy to use; when the filter 4 is cleaned, the staff releases the hexagonal cross 413, and the hexagonal cross 413 moves downward under the action of gravity. The hexagonal cross 413 resets downward and disengages from the power output shaft 54. At this time, the brush 414 no longer moves, and the dust swept by the brush 414 will accumulate in the dust collection box. The staff can regularly open the dust collection box, clean up the dust inside, and then put the dust collection box back into the fixed frame.

[0041] Example 2

[0042] On the basis of Example 1, Figure 4-Figure 8 As shown, it also includes an inflation device 7, which is provided on the filter replacement device 6.

[0043] When the L-shaped strong magnet 61 drives the square strong magnet 62 to move along the semicircular groove of the air filter chamber 2, the square strong magnet 62 will contact the arc piston 72 and squeeze the arc piston 72 to move, and the compression spring 74 will be compressed. Under the action of pressure, the air in the arc cylinder 71 will be squeezed and enter the air supply pipe 73 through the one-way air outlet pipe, and then pass into the straight cylinder 412. Under the action of pressure, the air in the straight cylinder 412 will push the hexagonal cross 413 to move upward. The upward movement of the hexagonal cross 413 will be stuck in the slot of the power output shaft 54, driving the brush 414 to work and clean the filter screen 4 on the side replaced last time, thereby reducing manual operation and allowing the brush 414 to clean the filter screen 4 more punctually and accurately, allowing the present invention to work efficiently; when the square strong magnet 62 is reset, it will disengage from the arc piston 72, and the reset of the compression spring 74 will drive the arc piston 72 to reset, while the hexagonal cross 413 will move downward under the action of gravity.

The air blowing device 8 includes an air guide pipe 81, an air distribution plate 82 and a hose 83. One end of the air guide pipe 81 is connected to the bottom of the straight cylinder 412 and is communicated with the straight cylinder 412. The other end of the air guide pipe 81 is provided with a one-way air outlet valve. The air distribution plate 82 is connected to the one-way air outlet valve of the air guide pipe 81 and is communicated with the air guide pipe 81. The air distribution plate 82 is communicated with the brush 414. The air distribution plate 82 is used to divert air.

A plurality of air outlet holes 84 are provided on the side of the brush 414 close to the filter 4.

[0046] When the hexagonal cross 413 moves upward, under the action of the one-way air outlet valve of the air guide pipe 81, the air guide pipe 81 will not inhale. When the hexagonal cross 413 is reset downward, the air in the straight cylinder 412 will be pushed onto the air guide pipe 81, and then the air will be diverted through the air distributor 82. The diverted air will be transported to the brush 414 through the hose 83, and will be blown out evenly through the several air outlet holes 84 on the brush 414.
