[0025] The upper side wall of the water tank 1 is provided with a feeding barrel 17 connected thereto, and a barrel cover 18 is provided in the feeding barrel 17. By opening the barrel cover 18, various materials can be easily added to the water tank 1 through the feeding barrel 17, which is convenient and quick. After closing the barrel cover 18, it can be sealed to ensure that the temperature in the water tank 1 is stable.

[0026] A fixing plate 19 is fixedly connected to the side wall of the water tank 1, and a disinfection box 20 is fixedly connected to the upper side wall of the fixing plate 19. The upper end of the disinfection box 20 extends into the feeding bucket 17. An inflation device is provided on the side wall of the disinfection box 20, and the inflation device is connected to the support rod 6. A guide pipe 21 is provided on the side wall of the disinfection box 20, and a nozzle 22 is provided at one end of the guide pipe 21 away from the disinfection box 20.

When the air pressure in the disinfection box 20 increases, the disinfectant can be squeezed out of the disinfection box 20 and then sprayed into the water. The water flow rotates and sprays the disinfectant evenly, so that the disinfectant contacts the swimming pool water more evenly, thereby improving the disinfection effect.

[0027] The inflatable device includes a cam 23 and an inflatable airbag 24. The cam 23 is fixedly sleeved on the support rod 6. The inflatable airbag 24 is installed below the fixed plate 19.

[0031] When the present invention uses a cavitator to cavitate swimming pool water, a driving motor 2 is used to drive a high-speed wheel 4 to rotate, thereby utilizing the high rotation of the high-speed wheel 4 to cavitate the swimming pool water, thereby utilizing the high temperature generated during cavitation to heat and disinfect the swimming pool water. At the same time, the rotating shaft 3 can drive the bevel gear 1 5 and the bevel gear 2 7 to rotate, thereby driving the support rod 6 and the connecting rod 8 to rotate, the connecting rod 8 drives the power gear 9 to rotate, the power gear 9 cooperates with the gear ring 11 to drive the annular heater 10 to rotate, the annular heater 10 drives the stirring blade 12 to rotate, and the annular heater 10 and the stirring blade 12 rotate in the opposite direction to the high-speed wheel 4, so that the inner circle and the outer circle of the water flow can be driven to rotate in the opposite direction, so that the water flow can contact the power wheel faster, accelerate the cavitation rate, and make the annular heater 10 contact the water in the water tank 1 more uniformly, thereby improving the heating effect.
