A blanking shell 7 is welded to the bottom of the filter box 1, and the bottom of the blanking shell 7 is connected with a discharge nozzle 8, and the blanking shell 7 is respectively connected with the left filter cartridge 6 and the right filter cartridge 10. The grease impurities are easily entered into the slag shell 13 through the slope surface 19 at the opening 18. In order to prevent grease from accumulating in the slag shell 13, a filter screen (not shown in the figure) corresponding to the aperture of the filter disc 14 is also embedded in the bottom surface of the slag shell 13. For the waterproof motor 11, the control mode of the utility model is to control it by manually starting and shutting down the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the utility model is mainly used to protect the mechanical device, so the control mode and wiring arrangement are no longer explained in detail in the utility model.

[0025] In one embodiment, the outer surface of the waterproof motor 11 is covered with a waterproof shell, and a fixed block 17 connected to the inner wall of the left filter cartridge 6 or the right filter cartridge 10 is provided on the side of the waterproof shell.
