Detailed Implementation

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0023] like Figs. 1-2 As shown, a disinfection device for drinking water production includes a tank 1, an ozone generator 2 externally mounted on the tank 1, and the tank 1 and ozone generator 2 connected by a gas supply pipe 22. The tank 1 has an inlet 3 at its top and a first outlet 5 at its bottom. A lifting plate 4 is installed inside the tank 1, which can slide up and down relative to the tank 1. The lifting plate 4 has several through holes 6 and several puncture elements 7 for puncturing air bubbles on its lower surface. A rotating rod 8 is located below the lifting plate 4, horizontally mounted and rotatably installed on the tank 1. Two cams 9 are fitted onto the rotating rod 8, overlapping the lower surface of the lifting plate 4. One end of the rotating rod 8 extends out of the tank 1 and is connected to a motor 13. Driven by the motor 13, the two cams 9 rotate, causing the lifting plate 4 to rise and fall, puncturing the air bubbles with the puncture elements 7. During the rising and falling of the puncture elements 7, the puncture elements 7 and the rotating rod 8 do not interfere with each other. The puncture elements 7 can be blades or conical protrusions. Several springs 20 are connected to the lower surface of the lifting plate 4 and the inner wall of the tank 1. The springs 20 cause the lifting plate 4 to tend to move downward.

[0024] Specifically, when motor 13 rotates, it drives rotating rod 8 to rotate, which in turn drives cam 9 to rotate. When cam 9 rotates, lifting plate 4 moves up and down, causing piercing element 7 to move up and down as well. During its up-and-down movement, piercing element 7 encounters small air bubbles, breaking them up and releasing the ozone within, thus preventing the formation of large air bubbles as they rise. Spring 20 is in a tensioned state, causing lifting plate 4 to tend to move downwards. The cooperation of spring 20 and cam 9 ensures smooth lifting and lowering of lifting plate 4, improving the efficiency of the blade or conical protrusion in piercing air bubbles. Lifting plate 4 can stir drinking water during its lifting and lowering process, and cam 9 can also stir drinking water during its rotation, promoting the mixing of ozone and drinking water and improving the disinfection effect. Piercing element 7 and rotating rod 8 do not interfere with each other, so piercing element 7 will not damage rotating rod 8 when it descends to its lowest point.

[0025] A stirring component is located above the rotating rod 8. This stirring component includes a rotating shaft 10, which is horizontally positioned and rotatably mounted on the tank body 1. Several stirring paddles 11 are mounted on the rotating shaft 10, and one end of the shaft 10 extends outside the tank body 1. A transmission component is located outside the tank body 1 between the rotating shaft 10 and the motor 13, and can control the rotation of the rotating shaft 10. The transmission component includes a driving wheel 12, which is connected to the output shaft of the motor 13. A driven wheel 14 is located below the driving wheel 12 and connected to the rotating shaft 10. A matching conveyor belt 15 is fitted between the driving wheel 12 and the driven wheel 14.

[0026] A sterilization chamber 16 is located at the bottom of the tank body 1. The first water outlet 5 of the tank body 1 and the sterilization chamber 16 are connected by a water outlet pipe 17. A second water outlet 19 is located on the side wall of the sterilization chamber 16, and a drain pipe 21 is connected to the second water outlet 19. A drain valve is installed on the drain pipe 21. A control valve is installed on the gas supply pipe 22, and a water outlet valve is installed on the water outlet pipe 17. Several ultraviolet lamps 18 are installed inside the sterilization chamber 16. The ultraviolet lamps 18 are connected to an external power source and switch via wires.

[0027] The output of the motor 13 drives the drive wheel 12 to rotate. The drive wheel 12, through the conveyor belt 15, synchronously drives the driven wheel 14 to rotate, which in turn drives the rotating shaft 10 to rotate, ultimately driving the agitator 11 to rotate. The agitator 11 promotes the mixing of ozone and drinking water, improving the disinfection effect of the drinking water. The ozone-disinfected drinking water flows into the sterilization tank 16 through the outlet pipe 17. The ultraviolet lamp 18 in the sterilization tank 16 further disinfects the drinking water, and finally it flows out from the second outlet 19 on the sterilization tank 16.

[0028] Detailed operation process

[0029] When the puncture element 7 is a blade, drinking water is first introduced into tank 1 through the inlet 3. The ozone generator 2 is then started, and the control valve on the gas supply pipe 22 is opened to introduce ozone into tank 1. The motor 13 is then started, and its output drives the drive wheel 12 to rotate. The drive wheel 12 drives the rotating rod 8 and cam 9 to rotate synchronously. The rotation of cam 9 causes the lifting plate 4 to move up and down, which in turn causes the blade to move up and down. During this movement, the blade breaks up and punctures the small air bubbles at the bottom of the small tank 1, releasing the ozone inside. Simultaneously, the drive wheel 12 drives the driven wheel 14 to rotate synchronously via the conveyor belt 15. The driven wheel 14 drives the rotating shaft 10 to rotate, which in turn drives the stirring paddle 11. The lifting plate 4, cam 9, and stirring paddle 11 stir the drinking water, ensuring thorough mixing of ozone and drinking water, and promoting the redissolution of the released ozone in the drinking water. Then, the outlet valve on the outlet pipe 17 is opened, and the ozone-disinfected drinking water flows from the first outlet 5 of tank 1 into the sterilization chamber 16. Turn on the ultraviolet lamp 18 to further disinfect the drinking water. After disinfection, open the drain valve on the drain pipe 21 and the drinking water flows out from the second outlet 19.
