Since the cleaning roller is in contact with the filter element, when the cleaning roller slides, it will rotate along with it, thereby enhancing the cleaning effect. Since the slider is limited and slides in the slide groove, rotating the threaded rod can drive the slider to slide, making the cleaning operation more convenient. By starting the motor, the output shaft of the motor drives the threaded rod to rotate, thereby further improving the convenience of operation. After cleaning, the vacuum cleaner can be started so that the cleaned dust is sucked into the vacuum cleaner through the cleaning groove, preventing the dust from falling into the shell and being re-adsorbed on the filter body.

Since the cleaning roller 34 is in contact with the filter element, the cleaning roller 34 will rotate as it slides, thereby enhancing the cleaning effect, thereby avoiding the situation where the high-efficiency air filter is usually disassembled for cleaning, which makes the operation very troublesome and increases the workload of the staff. Since the slider 32 slides in the slide groove 31, rotating the threaded rod 38 can drive the slider 32 to slide, making the cleaning operation more convenient. By starting the motor 39, the output shaft of the motor 39 drives the threaded rod 38 to rotate, thereby further improving the convenience of operation. After the cleaning is completed, the vacuum cleaner 37 can be started so that the cleaned dust is removed by the cleaner. The cleaning groove 36 is sucked into the vacuum cleaner 37 to prevent dust from falling into the shell 2 and being re-adsorbed on the filter body 1. The fixing block 35 can limit the upper slider 32 to prevent the lower slider 32 from sliding onto the cleaning groove 36 and blocking the cleaning groove 36. When the filter body 1 reaches the end of its service life, the four mounting blocks 42 can be separated from the mounting groove 41 to facilitate the removal of the filter body 1 for replacement. When the filter body 1 is connected to the shell 2, the round rod 43 can be inserted into the round groove 44 to make the connection between the filter body 1 and the shell 2 more stable. When the connecting rod 45 is pulled upward, the spring 46 is in a compressed state. Therefore, when the round rod 43 contacts the round groove 44, the connecting rod 45 is released, and the round rod 43 is stuck into the round groove 44 under the rebound elastic force of the spring 46, making the installation operation more convenient.
