[0037] The movable frame 7 is arranged inside the liquid storage tank 2. The movable frame 7 is arranged inside the liquid storage tank 2. When the protective cover 4 is opened, the movable frame 7 will be driven to move out.

[0038] A moving component is arranged on the outside of the liquid storage tank 2, and the moving component is fixedly connected to the moving frame 7. The moving component includes a rotating rod 6 rotatably connected to the protective shell 5. A rotating rod 64 is rotatably arranged in the inner wall of the bottom of the liquid storage tank 2. The output end of the motor 3 is connected to the rotating rod 64 through a second synchronous belt transmission connection, and the rotating rod 6 and the rotating rod 64 are rotatably connected through a first synchronous belt 61. One end of the rotating rod 6 is fixedly connected to a rotating plate 62, and a movable frame 63 is slidably connected to one side of the liquid storage tank 2. Both sides of the movable frame 63 are fixedly provided with movable blocks. A groove for the movable block to move is provided on one side of the liquid storage tank 2 to facilitate the movement of the movable block. One end of the rotating plate 62 is rotatably connected to a mounting shaft, and the mounting shaft is slidably arranged in the movable frame 63. One end of the movable frame 63 is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the moving frame 7. A groove for the connecting plate to move is provided on the surface of the liquid storage tank 2. A groove is provided on the surface of the liquid storage tank 2 to facilitate the connecting plate to drive the moving frame 7 to move.

[0039] A rotating assembly is arranged inside the liquid storage tank 2, and the rotating assembly includes a connecting rod 8. The output end of the motor 3 is fixedly connected to a mounting plate, the mounting plate is fixedly connected to the connecting rod 8, one end of the connecting rod 8 is rotatably connected to the protective cover 4, one end of the liquid storage tank 2 is rotatably connected to a rotating shaft 81, one end of the rotating shaft 81 is fixedly connected to a connecting frame 82, a T-shaped limiting block is fixedly provided on one side of the protective cover 4, a slot matching the limiting block is opened on one side of the connecting frame 82, and the connecting frame 82 is slidably provided on the outside of the limiting block.
