The filter screen cleaning device provided by the embodiment of the application drives the filter screen 100 to move through the driver, and cleans the filter screen 100 moved in place through the cleaner 200, so as to separate dust on the filter screen 100 from the filter screen 100, the separated dust enters the collecting member 300 through the collecting port and is discharged through the discharge port, and meanwhile, the dust entering the collecting member 300 is fluidized through the fluidizer 31, that is, the dust in the collecting member 300 is fully vibrated, so that fine particles, scraps and the like attached to the inner wall of the collecting member 300 can fall off from the inner wall under the vibration condition, and after the filter screen 100 is cleaned, the inner wall of the collecting member 300 has no attachments, and after the cleaning is finished, the filter screen 100 is manually opened, the collecting member 300 is detached, the dust in the device is secondarily collected or secondarily cleaned, and the self-cleaning effect of the collecting member 300 in the process is realized, the good sewage discharge effect is achieved, and meanwhile, the labor and the time are saved.

Preferably, in the embodiment, the fluidizer 31 is a vibrator, and the vibrator is fixedly connected to the sidewall of the collecting member 300, so that the dust in the collecting member 300 is fluidized by the vibrator and discharged through the discharge port. Specifically, the vibrator may be an ultrasonic motor, a linear motor, or a rotor motor with a bias weight. The ultrasonic motor has the largest vibration frequency, and the cleaning effect on the inner wall of the collecting piece 300 is better.

The ultrasonic motor is an actuator using mechanical vibration in an ultrasonic frequency range as a drive source. A linear motor is a transmission device that directly converts electric energy into mechanical energy for linear motion without any intermediate conversion mechanism. The rotary motor can be seen as being formed by cutting a rotary motor in the radial direction and expanding the rotary motor into a plane. The rotor motor with the eccentric weights is characterized in that a group of adjustable eccentric blocks are respectively arranged at two ends of a rotor shaft through a vibration motor, and an excitation force is obtained by utilizing a centrifugal force generated by high-speed rotation of the shaft and the eccentric blocks.
