When the sewage enters the housing 1, the motor 31 is started, and the rotation of the motor 31 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the toggle rod 33 to rotate, so that the sewage can be stirred to avoid sediment deposition in the sewage, thereby avoiding clogging of the filter plate 1 35, thereby maintaining the water flow. The fluidity of the liquid is ensured by the following steps: the partition 34 is fixedly connected to the inner wall of the shell 1, the filter plate 1 35 is fixedly connected to the inner wall of the partition 34, the fixed plate 2 36 is fixedly connected to the left side of the partition 34, the spring 1 37 is fixedly connected to the top of the fixed plate 2 36, the activated carbon plate 38 is fixedly connected to the circumferential surface of the rotating rod 32, and the activated carbon plate 38 is located on the right side of the toggle rod 33, the stirring plate 39 is fixedly connected to the circumferential surface of the rotating rod 32, and the stirring plate 39 is located on the right side of the activated carbon plate 38, the fixed column 310 is fixedly connected to the right side of the stirring plate 39, the filter plate 2 311 is fixedly connected to the top of the spring 1 37, the rubber soft plate 312 is fixedly connected to the bottom of the filter plate 2 311, and the circumferential surface of the rotating rod 32 is rotatably connected to the inner wall of the shell 1.

At the same time, when the toggle rod 33 rotates, the toggle rod 33 will contact the rubber soft plate 312, so that the rubber soft plate 312 moves upward, and the rubber soft plate 312 drives the second filter plate 311 to move. At the same time, when the toggle rod 33 contacts the rubber soft plate 312, the spring 1 37 will reduce the weight of the second filter plate 311 , so that the force received by the toggle rod 33 when in contact with the rubber soft plate 312 is reduced, the impact force received by the toggle rod 33 is reduced, and the toggle rod 33 is prevented from being damaged, so that the filter plate 311 vibrates so that the sludge accumulated on the top of the filter plate 311 can be shaken, and the water in the sludge can be vibrated out while avoiding the clogging of the filter plate 311. At the same time, after the sewage flows into the filter plate 35, the rotating rod 32 drives the activated carbon plate 38 to rotate, so that impurities in the sewage can be adsorbed, and the cleaning effect of the sewage can be enhanced. The rotating rod 32 drives the stirring plate 39 to rotate, and the stirring plate 39 drives the fixed column 310 to rotate, so that the medicine flowing out of the medicine box 4 can be stirred, which is convenient for the diffusion of the medicine.

The push plate 73 is fixedly connected to the top of the protrusion 74, and the bottom of the medicine box 4 is fixed to the top of the pipe 72. The rotating plate 71 is connected to the fixed column 310, the surface of the push plate 73 is in contact with the inner wall of the outer shell 1, the surface of the protrusion 74 is in contact with the inner wall of the fixed plate three 75, and the bottom of the push plate 73 is in contact with the top of the fixed plate three 75. At the same time, when the fixed column 310 rotates, the fixed column 310 will contact the rotating plate 71, so that the fixed column 310 pushes the rotating plate 71 to rotate. When the rotating plate 71 rotates to block the water outlet of the medicine box 4, the medicine will no longer flow out. When the rotating plate 71 rotates without blocking the water outlet of the medicine box 4, the medicine will flow out along the pipe 72 and enter the interior of the outer shell 1, so that the intermittent closure of the medicine outlet can be achieved to avoid excessive flow of medicine and cause waste.

At the same time, after the sewage flows into the filter plate 1 35, the rotating rod 32 drives the activated carbon plate 38 to rotate, so that impurities in the sewage can be adsorbed and the cleaning effect of the sewage can be enhanced. The rotating rod 32 drives the stirring plate 39 to rotate, and the stirring plate 39 drives the fixed column 310 to rotate, so that the medicine flowing out of the medicine box 4 can be stirred, which is convenient for the diffusion of the medicine.

[0016] When the medicine is being stirred, the activated carbon plate 38 rotates and contacts with the protrusion 74, so that the activated carbon plate 38 drives the protrusion 74 to move back and forth, and the movement of the protrusion 74 drives the push plate 73 to move, so that the sludge can be lifted up, which is convenient for the subsequent links to crush the sludge on the push plate 73. At the same time, when the fixed column 310 rotates, the fixed column 310 will contact the rotating plate 71, so that the fixed column 310 pushes the rotating plate 71 to rotate. When the rotating plate 71 rotates to block the water outlet of the medicine box 4, the medicine will no longer flow out. When the rotating plate 71 rotates without blocking the water outlet of the medicine box 4, the medicine will flow out along the pipe 72 and enter the interior of the shell 1, so that the intermittent closure of the medicine outlet can be achieved to avoid excessive flow of the medicine and cause waste.
