[0015] (1) The invention pushes away the impurities accumulated at the bottom of the purification box by moving the push plate to prevent the impurities from accumulating. At the same time, the push plate drives the L-shaped rod to move in the direction away from the motor. When the L-shaped rod moves to the end of the guide frame away from the motor, the L-shaped rod rises along the inclined surface of the guide frame. The rise of the L-shaped rod drives the push plate to move upward. The upward movement of the push plate will break away from the contact with the purification box. The moving frame drives the elastic telescopic rod and the push plate to reset, so that the push plate breaks away from the contact with the purification box during the reset process, thereby preventing impurities from floating freely inside the purification box and affecting the purification effect.

[0016] (2) In the invention, when the push plate moves away from the motor, it will contact the sliding seat. The push plate will push the sliding seat to move away from the motor. The movement of the sliding seat away from the motor will push the rotating rod to rotate. The rotation of the rotating rod will push the sliding block to move downward. The downward movement of the sliding block will drive the rotating plate to rotate downward. The downward rotation of the rotating plate will open the sewage outlet to discharge impurities at the bottom of the purification box to prevent impurities from accumulating and affecting the purification effect. At the same time, the downward rotation of the rotating plate will drive the pulley frame to rotate downward. The downward rotation of the pulley frame will push the trapezoidal block to move downward. The downward movement of the trapezoidal block will drive the sealing connecting plate to move downward. The downward movement of the sealing connecting plate will overlap and seal with the sealing ring to prevent a large amount of water from being discharged along with the sewage outlet when the rotating plate is opened, causing waste.

[0017] (3) The invention drives the fixed seat to move away from the motor by moving the sliding seat in the direction away from the motor, so that the liquid oxidant in the feed box enters the purification box, which helps to decompose organic pollutants, ammonia nitrogen and sulfide in the water. At the same time, the upward movement of the sealing plate drives the long rod to move upward, and the upward movement of the long rod drives the rack to move upward. The upward movement of the rack drives the tooth block to rotate, and the rotation of the tooth block drives the stirring rod to rotate. The rotation of the stirring rod drives the stirring blade to rotate. The rotation of the stirring blade improves the mixing effect of the liquid oxidant and prevents liquid precipitation due to long-term storage, which affects the purification effect.
