[0025] Working principle: During use, first connect the air inlet pipe 13 to the air outlet pipe of the paint spraying room, then start the fan 6 through the controller 8, and the fan 6 draws the air in the conical bin cover 4 through the air pipe. Under the action of atmospheric pressure, the air in the paint spraying room is sucked into the air inlet pipe 13, and the air enters the filter bin 3 through the air inlet pipe 13, and then enters the telescopic bellows 16 through the inside of the filter element 18 after being filtered by the filter element 18. The filtered air is transported to the conical bin cover 4 by the telescopic bellows 16 and is drawn away by the fan 6 and transported to the next processing device. When the filter element 18 needs to be replaced, the filter element 18 is replaced by the fan 6. The fan 6 is turned off through the controller 8, and the box cover 5 is opened by pulling the pull ring on the box cover 5 by external force, and then the electric push rod 15 is controlled to retract through the controller 8, and the end of the electric push rod 15 drives the plug connector 17 to move upward until the plug connector 17 leaves the inside of the filter element 18, and then the motor 23 is controlled to start through the controller 8, and the driving end of the motor 23 drives the gear 24 to rotate. Since the gear 24 is meshed and connected with the gear guide rail 9, the rotation of the gear 24 drives the motor 23 to move, and the movement of the motor 23 drives the fixed base 20 to move, and the movement of the fixed base 20 drives the filter element 1 8 moves until the filter element 18 completely enters the core changing box 7. At this time, the motor 23 is turned off by the controller 8, and then the filter element 18 is twisted by external force. The rotation of the filter element 18 drives the block 21 to rotate until the top of the block 21 is separated from the fixed base 20. Then the filter element 18 is lifted to the outside of the core changing box 7 by external force, and then a new filter element 18 is taken, and the block 21 is aligned with the card slot 19 and inserted. Then the filter element 18 is twisted by external force to fix it, and then the motor 23 is controlled to reverse by the controller 8. The driving end of the motor 23 drives the gear 24 to rotate, and the gear 24 drives the motor 23 Move toward the filter bin 3, the movement of the motor 23 drives the fixed base 20 to move, and the movement of the fixed base 20 drives the filter element 18 to move, until the fixed base 20 is close to the side of the rubber gasket 10 away from the top rod 11, and the motor 23 is controlled to be closed through the controller 8, and then he makes a controller 8 to control the electric push rod 15 to extend, and the end of the electric push rod 15 drives the plug connector 17 to move downward, until the plug end of the plug connector 17 is inserted into the interior of the filter element 18, and then the box cover 5 is rotated by external force to cover the core replacement box 7, and then the fan 6 is controlled by the controller 8 to start and continue to filter harmful air.
