[0026] The above technical solution can avoid messy wiring, provide unified power supply, and also serve as a backup power source. When the external power supply fails, it can provide auxiliary power supply to prevent damage to the equipment.
[0027] A feed hopper 6 is fixedly connected to the top of one side of the filter box 7. The feed hopper 6 is circular.
[0028] The above technical solutions facilitate the transportation and discharge of water sources;
[0029] The top of both sides of the inner cavity of the filter box 7 is fixedly connected with a guide plate 13, which is inclined.
[0030] Through the technical scheme, the water source can be guided and transported;
