[0001] The utility model relates to the technical field of drinking water disinfection equipment, in particular to an ozone and ultraviolet integrated disinfection device for direct drinking water. Background Technique

[0002] Direct drinking water refers to water that is free of pollution and degradation and meets the physiological needs of the human body and can be directly drunk. Usually, it needs to be disinfected by a disinfection device to kill bacteria and other harmful microorganisms in the water.

By dissolving ozone into the water and irradiating it with ultraviolet light simultaneously, most of the harmful microorganisms in the water can be killed to ensure the safety of drinking water. However, there are some functional deficiencies in the actual use process, and there is still room for improvement. For example, ozone is mostly directly input into the water tank through a pipeline, with a small contact area with water, a low dissolved water volume, and mostly floating in the voids at the top of the water tank. There is still room for improvement in the sterilization effect, and it does not have the function of boosting pressure to promote the dissolution of ozone in water.

[0007] The pressure boosting component includes a pressure boosting pipe, the pressure boosting pipe is fixedly connected to one side inside the water storage tank, a piston rod is vertically inserted into the top end of the pressure boosting pipe, and a one-way valve is fixedly connected to the top of one side of the pressure boosting pipe.

[0008] Preferably, a water inlet is fixedly connected to the top of one side of the water storage tank, and the ozone delivery pipe, the pressurizing pipe, and the inside of the one-way valve are connected.

[0009] Preferably, an electric cylinder is installed on one side of the top of the water storage tank, and the top end of the piston rod is connected to the bottom end of the electric cylinder.

[0010] Preferably, an air outlet head is fixedly connected to the bottom of the pressurizing pipe, and fine holes are evenly arranged inside the air outlet head.

[0013] Preferably, a housing is arranged on the left side of the water pump. A stainless steel filter screen is horizontally placed at the bottom end inside the housing. A limiting ring is fixedly connected to the top of the stainless steel filter screen. The bottom of the housing is threadedly connected with a bottom cover. A water inlet pipe is fixedly connected between the top of the housing and the bottom of the other side of the water storage tank. A water outlet pipe is fixedly connected between one side of the housing and the other side of the water pump.

[0014] Preferably, the outer diameter of the limiting ring is the same as the inner diameter of the housing, and the outer diameter of the stainless steel filter screen is smaller than the inner diameter of the housing.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The ozone and ultraviolet integrated disinfection device for direct drinking water not only realizes the function of pressurizing and promoting ozone dissolution in water, but also realizes the function of monitoring the water output, and also realizes the function of facilitating slag and scale removal;

[0016] (1) By setting up an electric cylinder, a supercharging pipe, a piston rod, a one-way valve, and an air outlet head, during use, tap water enters the water storage tank along the water inlet. The ozone generator generates ozone and sends it into the water storage tank through the ozone delivery pipe. The ozone dissolves in water to disinfect the inside of the water storage tank. The ultraviolet germicidal lamp irradiates synchronously to kill harmful microorganisms in the water. The ozone oxidizes bromide ions in the water into bromate, and the reverse osmosis membrane in the filter cartridge can filter it out. The water after filtration is directly drinkable water. During the process of inputting ozone, the ozone enters the supercharging pipe through the one-way valve. The electric cylinder presses down regularly, pushing the piston rod to move downward along the supercharging pipe, and pressing the ozone in the supercharging pipe out along the air outlet head. The ozone emerges through the fine holes on the surface of the air outlet head, forming fine bubbles, which can increase the dissolution amount with water. When the electric cylinder retracts, part of the water body is brought into the supercharging pipe by the piston rod. As the amount of ozone in the supercharging pipe continuously increases, the water body is squeezed out again, and then the electric cylinder extends downward again to press out ozone. This cycle repeats, thus realizing the function of promoting ozone dissolution in water by supercharging;

[0017] (2) By setting up an outlet flowmeter, a data cable, and a flowmeter main unit, during use, the sterilized water body is transported by a water pump into the filter cartridge. The reverse osmosis membrane in the filter cartridge filters out the bromate in the water. The water after filtration enters the outlet pipe along the water collecting pipe. The outlet flowmeter can monitor the water collecting pipe corresponding to the filter cartridge in real time and feedback the data to the flowmeter main unit through the data cable, which is convenient for the staff to check. When the flow data of a single water collecting pipe is abnormal, it indicates that there may be a problem with the corresponding filter cartridge, and it needs to be repaired in time, thus realizing the function of monitoring the water output;

[0018] (3) By setting up a housing, a limiting ring, a stainless steel filter screen, a bottom cover, a water inlet pipe, and a water outlet pipe, when the water storage tank is descaled regularly, the scale inside it falls off under the action of the descaling agent and is sucked out by the water pump and enters the housing along the water inlet pipe. The stainless steel filter screen inside the housing can intercept large pieces of scale, preventing it from directly entering the filter cartridge and shortening the service life of the reverse osmosis membrane. The intercepted water body then drains out along the water outlet pipe. The operator can open the bottom cover to take out the stainless steel filter screen for cleaning. The limiting ring on the top of the stainless steel filter screen can limit its position to keep it upright, thus realizing the function of facilitating slag and scale removal.

[0027] At the top of one side of the water storage tank 4, a water inlet 6 is fixedly connected. The ozone delivery pipe 5, the pressurizing pipe 8, and the check valve 10 are internally connected. An electric cylinder 7 is installed on one side of the top of the water storage tank 4. The top end of the piston rod 9 is connected to the bottom end of the electric cylinder 7.

By pressurizing and discharging ozone, its water solubility can be improved;

[0028] Specifically, as Figure 1 and Figure 2 shown, ozone enters the pressurizing pipe 8 through the check valve 10. The electric cylinder 7 periodically presses down, pushing the piston rod 9 to move down along the pressurizing pipe 8, and pressing the ozone in the pressurizing pipe 8 out along the air outlet head 11.

The electric cylinder 7 retracts, and part of the water body is brought into the pressurizing pipe 8 by the piston rod 9. As the amount of ozone in the pressurizing pipe 8 continuously increases, the water body is squeezed out again, and then the electric cylinder 7 extends downward again to press out ozone, and so on in a cycle.

[0029] Embodiment 2: An effluent flowmeter 20 is arranged between the water collecting pipe 18 and the water outlet pipe 19. A flowmeter main unit 22 is installed at the bottom of the front end of the filter support frame 14.

When the flow rate data of a single water collecting pipe 18 is abnormal, it means that the corresponding filter cartridge tank 16 may have problems and needs to be repaired in time.

[0031] Embodiment 3: A housing 23 is arranged on the left side of the water pump 13. A stainless steel filter screen 25 is horizontally placed at the bottom inside the housing 23. A limiting ring 24 is fixedly connected to the top of the stainless steel filter screen 25. The bottom of the housing 23 is threadedly connected with a bottom cover 26.

The limit ring 24 at the top of the stainless-steel filter screen 25 can restrict its position and keep it upright.

[0033] Working principle: When the present utility model is in use, first, tap water enters the water storage tank 4 along the water inlet 6. The ozone generator 3 generates ozone and sends it into the water storage tank 4 through the ozone delivery pipe 5. The ozone dissolves in the water to disinfect the inside of the water storage tank 4. The ultraviolet germicidal lamp 12 irradiates synchronously to kill harmful microorganisms in the water. The ozone oxidizes bromide ions in the water into bromate, and the reverse osmosis membrane 17 in the filter cartridge 16 can filter it out. The filtered water is the direct drinking water. During the process of inputting ozone, the ozone enters the pressurizing pipe 8 through the one-way valve 10. The electric cylinder 7 periodically presses down, pushing the piston rod 9 to move down along the pressurizing pipe 8, and pressing the ozone in the pressurizing pipe 8 out along the air outlet head 11. The ozone emerges through the fine holes on the surface of the air outlet head 11 to form fine bubbles, which can increase the dissolution amount with the water. The electric cylinder 7 retracts, and part of the water body is brought into the pressurizing pipe 8 by the piston rod 9. As the amount of ozone in the pressurizing pipe 8 continuously increases, the water body is squeezed out again. Then the electric cylinder 7 extends downward again to press out ozone, and so on in a cycle. The sterilized water body enters the filter cartridge 16 under the transportation of the water pump 13. The reverse osmosis membrane 17 in the filter cartridge 16 filters out the bromate in the water. The filtered water enters the water outlet pipe 19 along the water collecting pipe 18. The water outlet flowmeter 20 can monitor the water collecting pipe 18 corresponding to the filter cartridge 16 in real time and feedback the data to the flowmeter main unit 22 through the data line 21, which is convenient for the staff to check. When the flow data of a single water collecting pipe 18 is abnormal, it indicates that there may be a problem with the corresponding filter cartridge 16, and it needs to be repaired in time. When the water storage tank 4 is descaled regularly, the scale inside it falls off under the action of the descaling agent and is sucked outwards by the water pump 13 and enters the housing 23 along the water inlet pipe 27. The stainless-steel filter screen 25 inside the housing 23 can intercept large pieces of scale, preventing them from directly entering the filter cartridge 16 and shortening the service life of the reverse osmosis membrane 17. The intercepted water then drains out along the water outlet pipe 28. The operator can open the bottom cover 26 to remove the stainless-steel filter screen 25 for cleaning. The limit ring 24 at the top of the stainless-steel filter screen 25 can restrict its position and keep it upright.
