[0098] When there is too much water stored in the water tank, it will be discharged through the overflow pipe. When the water is discharged through the overflow pipe, it will squeeze the sealing baffle to move, so that the overflow pipe opens to drain water. In normal state, the sealing baffle is blocked on the inside of the overflow pipe to prevent mosquitoes from entering the water tank through the overflow pipe.

[0099] When the motor is started, the filter element can be driven to rotate together. At the same time, the guide scraper can contact the surface of the filter element to scrape off the filter material adhered to the surface of the filter element. When the motor is started, the third gear can be rotated intermittently by toggling the tooth block, so that the guide scraper can swing under the pull of the first spring, thereby achieving the effect of facilitating the material guiding and avoiding the problem of filter material adhesion. At the same time, the first eccentric wheel, the second eccentric wheel and the linkage rod can be linked to drive the shaft rod to reciprocate, and then the knocking ball at the end of the traction rope can be driven to knock the lower surface of the guide scraper to vibrate, making it more convenient to unload materials.

[0100] The filter element is easy to disassemble and install. By pulling the clamping plate, the second block is disengaged from the inside of the recess. At this time, the round rod can slide along the inside of the filter element, so that it can be disengaged from the first block. At this time, it is easy to disassemble the filter element. After the filter element is installed, it can be tightly engaged with the inside of the recess through the first block under the squeezing and pulling of the second spring, so that the motor can drive the filter element to rotate and filter after starting.

[0101] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
