[0015] The present invention has the following beneficial effects:

[0016] (1) In the present invention, the filter cartridge is placed at the top center of the threaded square plate, and the motor is started. The motor drives the rotating shaft to rotate, and the rotating shaft drives the first toothed disc to rotate. The first toothed disc drives the first gear to rotate during the rotation process, and the first gear drives the threaded rod to rotate. During the rotation process, the threaded rod causes the threaded square plate to move upward, and the threaded square plate drives the filter cartridge to move upward. During the rising process of the filter cartridge, because the two magnetic blocks are in a state of like-charge repulsion and move away from each other, the magnetic block drives the vertical plate to rotate, so that the filter wall of the filter cartridge can be stuck between the two vertical plates, and the filter cartridge squeezes the clamping ring block to rise, so that the filter cartridge can be accurately positioned to prevent cleaning. The spring rope is deformed and the two semi-circular blocks are moved closer to each other, the semi-circular blocks drive the sealing cylinder to move closer to each other, the sealing cylinder drives the first sliding block to move closer to each other, the sealing cylinder drives the second return spring to move closer to each other, the second return spring drives the sliding rod to move closer to each other, the sliding rod drives the cleaning plates to move closer to each other, so that the inner and outer walls of the filter cartridge can be tightly fitted, and the rotating shaft drives the rotating disk to rotate, and the rotating disk drives the first sliding block to rotate, which indirectly enables the two cleaning plates to rotate around the filter cartridge for cleaning, thereby enhancing the cleaning effect of the device on the inner and outer walls of the filter cartridge.

[0017] (2) In the present invention, when the cleaning plate squeezes the filter cartridge, it is subjected to a reaction force, and the cleaning plate squeezes the sliding rod, and the sliding rod moves inside the sealing cylinder, so that the airflow inside the sealing cylinder enters the interior of the limiting tube, and the airflow pushes the connecting block inside the limiting tube, and the connecting block drives the first elastic rope to move, and the first elastic rope drives the disc to move. When the first elastic rope is no longer located inside the limiting tube, it is subjected to the elastic deformation of the first elastic rope, and the first elastic rope shrinks and shortens, driving the disc to move. During the movement of the disc, the disc bends, so that the elastic arc rods are combined to present an arc spherical shape, so that the elastic arc rods are in During the rotation around the inner wall of the filter cartridge, the elastic arc rod continuously elastically deforms and touches the inner wall of the filter cartridge to clean the inner wall of the filter cartridge, further enhancing the cleaning effect of the inner wall of the filter cartridge, and the two magnetic blocks are respectively located at the inner and outer walls of the filter cartridge. The magnetic blocks are attracted by the iron magnetism of the filter cartridge, so that the magnetic blocks and the filter cartridge are tightly fitted, and the magnetic blocks drive the vertical plate to fit the filter cartridge, and the vertical plate drives the heating plate to fit the inner and outer walls of the filter cartridge, so that the heating plate heats the filter cartridge to prevent the filter cartridge from being too wet, causing impurities to adhere to the inner and outer walls of the filter cartridge and unable to be removed, further enhancing the cleaning effect of the elastic arc rod on the inner wall of the filter cartridge.

[0018] (3) In the present invention, when the threaded rod rotates, the threaded rod drives the second gear to rotate, the second gear drives the second toothed disc to rotate, the second toothed disc drives the rotating rod to rotate, the rotating rod drives the connecting rod to rotate, the connecting rod drives the squeezing ball to rotate, the squeezing ball squeezes the separation airbag during rotation, the separation airbag is squeezed, the internal airflow passes through the bent pipe and enters the inside of the special-shaped tube and the round tube respectively, and is subjected to the elastic force of the second elastic rope, so that the sealing ball is always blocked at the tube mouth of the special-shaped tube to prevent the gas from spraying out, and the airflow is pressed against the second sliding part inside the round tube. When the separation air bag is no longer squeezed, the separation air bag generates negative pressure, and the negative pressure enters the interior of the special-shaped tube through the bent pipe. At this time, the sealing ball no longer blocks the special-shaped tube, and the negative pressure can absorb the dust cleaned out near the filter cartridge through the special-shaped tube to prevent the dust from adhering to the outer wall of the filter cartridge again, thereby enhancing the separation effect between the filter cartridge and the dust, and further enhancing the cleaning effect of the filter cartridge.
