[0042] The bottom of the inner cavity of the collecting box 1 is provided with a driving assembly, and the driving assembly drives the filter cartridge 3 to rotate.

[0043] The inner bottom surface of the collecting box 1 is fixedly connected with two protrusions 9 in symmetry. The bottom surface of the filter cartridge 3 is fixedly connected with a support frame 6, and the support frame 6 is composed of a disc and four support rods, and the four support rods are fixedly connected to the outer surface of the disc. When the filter cartridge 3 rotates, the four support rods are sequentially abutted with the protrusions 9. When the support rod rotates to the protrusion 9, the protrusion 9 will push the support rod upward; when the support rod rotates away from the protrusion 9, the support rod will move downward under the action of gravity.

The bottom surface of the filter cartridge 3 is fixedly connected with a support frame 6, and the support frame 6 is composed of a disc and four support rods, and the four support rods are fixedly connected to the outer surface of the disc. When the filter cartridge 3 rotates, the four support rods are in turn abutted with the protrusions 9. When the support rod rotates to the protrusion 9, the protrusion 9 will push the support rod upward; when the support rod rotates away from the protrusion 9, under the action of gravity, the support rod will move downward.

[0066] The top surface of the protrusion 9 is provided in a semispherical shape, and the bottom surface of the four support rods is provided in an arc shape. When the support rod contacts the protrusion 9, the support rod passes through the protrusion 9 conveniently.

[0067] The driving assembly includes a motor 7, and the motor 7 is fixedly connected to the inner bottom surface of the collecting box 1. The output end of the motor 7 is fixedly connected with a rotating shaft 8, and the top end of the rotating shaft 8 is a rectangular block.
