Technical Field
[0001] This utility model relates to the field of drinking water sterilization technology, and in particular to a drinking water sterilization device. Background Technology
[0002] To ensure the safety of drinking water and prevent the spread of diseases through drinking water, it is usually necessary to sterilize drinking water to kill or remove pathogens and other harmful microorganisms in the drinking water.
[0003] The existing patent publication number: CN219239459U describes a drinking water purification and sterilization device, which includes a mounting frame, a disinfection mechanism, and mounting components. A mounting cylinder is fixedly mounted on the top of the mounting frame. The disinfection mechanism is located inside the mounting cylinder and includes an ozone generator, an air pump, and an air guide pipe. A support plate is fixedly mounted on the inner side of the mounting frame, and a water pump and a water guide pipe are fixedly mounted on the top of the support plate. A set of air guide pipes is fixedly connected to the output end of the water pump. This drinking water purification and sterilization device can control the start of the ozone generator and air pump to blow ozone into the water through a jet nozzle, enabling secondary filtration of the disinfected drinking water through quartz stone, sponge, and activated carbon.
[0004] Currently, different sterilization methods are used to improve the quality of drinking water. However, when drinking water is sterilized multiple times, it is impossible to recirculate the water, which means that the drinking water cannot come into contact with different sterilization methods multiple times. As a result, it is not easy to kill bacteria that are difficult to kill. The aforementioned patented device does not mention this, which reduces the sterilization efficiency of drinking water. Utility Model Content
[0005] The purpose of this utility model is to provide a drinking water sterilization device, which solves the problem that current methods for sterilizing and disinfecting drinking water use different sterilization methods to improve water quality. However, when drinking water is sterilized multiple times, it cannot be refluxed, resulting in the drinking water not being able to come into contact with different sterilization methods multiple times. Consequently, it is not easy to kill bacteria that are difficult to eliminate. The aforementioned patented device does not address this issue, which reduces the sterilization efficiency of drinking water.
[0006] To achieve the above objectives, this utility model provides a drinking water sterilization device.
[0007] The device includes a working board, a left placement frame fixed to the top left side of the working board, a primary sterilization box fixed inside the left placement frame, a right placement frame fixed to the top right side of the working board, and a secondary sterilization box fixed inside the right placement frame.
[0008] The primary sterilization box includes a water inlet pipe on its outer left side, which is fixedly connected to the outside of the primary sterilization box and extends into the inside of the primary sterilization box at its right end. The secondary sterilization box has a water outlet pipe fixed on its outer right side, with its left end extending into the inside of the secondary sterilization box.
[0009] The primary sterilization box and the secondary sterilization box are fixed with a reflux structure. The reflux structure includes a reflux front pipe and a reflux rear pipe. The reflux front pipe and the reflux rear pipe have the same overall length, and both ends of the reflux front pipe and the reflux rear pipe penetrate into the inner side of the primary sterilization box and the secondary sterilization box. A reflux valve is provided at the top of the reflux front pipe and the reflux rear pipe.
[0010] The primary sterilization box has embedded frames fixed at both the front and rear ends of its inner wall, and ultraviolet irradiation lamps are fixed inside each of the two embedded frames. A controller is fixed on the rear side of the primary sterilization box, and the ultraviolet irradiation lamps are electrically connected to the controller.
[0011] The secondary sterilization box is rotatably connected to a stirring rod inside, and a side rod is fixedly arranged on the outside of the stirring rod. A motor is fixed on the right side of the outer side of the secondary sterilization box, and the output end of the motor extends into the interior of the secondary sterilization box and is fixedly connected to the stirring rod through a coupling.
[0012] Both the primary sterilization box and the secondary sterilization box are equipped with lids on their tops. A slot is passed through the top surface of the lid, and a card plate is fixed inside the slot. The card plate is transparent.
[0013] The secondary sterilization box has a dispensing tube fixed to the top right side, the bottom end of the dispensing tube extends into the interior of the secondary sterilization box, and the dispensing tube is set at an angle.
[0014] Both ends of the reflux pre-pipe and reflux post-pipe are fixed with snap rings, and the snap rings are circular in shape.
[0015] A water outlet valve is installed at the top of the water outlet pipe.
[0016] The interiors of both the left and right frames are smoothed.
[0017] This utility model discloses a drinking water sterilization device. When it is necessary to improve the sterilization effect, the reflux valve at the top of the reflux pipe can be opened to allow the drinking water inside the secondary sterilization box to flow back into the primary sterilization box. This causes the drinking water to flow between the primary and secondary sterilization boxes, allowing the sterilization method to act on the water more evenly and avoiding sterilization dead zones due to uneven water flow speed or distribution, thereby improving the sterilization effect of drinking water. By turning on the controller, the ultraviolet irradiation lamps inside the embedded frame are activated to irradiate the drinking water flow. The two ultraviolet irradiation lamps are set opposite each other to improve the irradiation sterilization efficiency of the drinking water flow. Hydrogen peroxide or sodium bicarbonate dilution solution is added into the secondary sterilization box through the dosing pipe. Then, the motor is turned on, causing the stirring rod to rotate with multiple side rods, so that the sterilizing agent can come into contact with the drinking water flow to achieve the secondary sterilization effect.

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0025] The first embodiment of this application is as follows:
[0026] Please see Figures 1-2A drinking water sterilization device includes a working plate 1. A left placement frame 2 is fixed to the top left side of the working plate 1, and a primary sterilization box 3 is fixed inside the left placement frame 2. A right placement frame 4 is fixed to the top right side of the working plate 1, and a secondary sterilization box 5 is fixed inside the right placement frame 4. The outer left side of the primary sterilization box 3 also includes a water inlet pipe 6, which is fixedly connected to the outside of the primary sterilization box 3, with its right end penetrating into the interior of the primary sterilization box 3. A water outlet pipe 7 is fixed to the outer right side of the secondary sterilization box 5, with its left end penetrating into the interior of the secondary sterilization box 5. The primary sterilization box 3 and the secondary sterilization box 5 are connected by a water inlet pipe 6. A reflux structure is fixed between the secondary sterilization boxes 5. The reflux structure includes a pre-reflux pipe 8 and a post-reflux pipe 9. The pre-reflux pipe 8 and the post-reflux pipe 9 have the same overall length, and both ends of the pre-reflux pipe 8 and the post-reflux pipe 9 extend into the inner sides of the primary sterilization box 3 and the secondary sterilization box 5. A reflux valve 10 is installed at the top of both the pre-reflux pipe 8 and the post-reflux pipe 9. In the existing technology, different sterilization methods are currently used to improve the water quality of drinking water. However, when drinking water is sterilized multiple times, it is impossible to reflux the drinking water, thus causing problems for the drinking water quality. Water cannot be repeatedly exposed to different sterilization methods, making it difficult to eliminate stubborn bacteria. This is not addressed in the aforementioned patented device, thus reducing the sterilization efficiency of drinking water. To address this issue, a reflux structure can be fixed between the primary sterilization box 3 and the secondary sterilization box 5. Specifically, drinking water is first introduced into the primary sterilization box 3 through the inlet pipe 6. Then, the sterilization structure inside the primary sterilization box 3 performs a primary sterilization of the drinking water. Finally, the reflux valve 10 at the top of the reflux pre-pipe 8 is opened to allow the drinking water inside the primary sterilization box 3 to be used. The drinking water flows into the secondary sterilization box 5, where it undergoes secondary sterilization through the sterilization structure. To improve the sterilization effect, the return valve 10 at the top of the return pipe 9 can be opened, allowing the drinking water in the secondary sterilization box 5 to flow back into the primary sterilization box 3. This causes the drinking water to flow between the primary sterilization box 3 and the secondary sterilization box 5, ensuring that the sterilization method acts more evenly on the water and avoiding sterilization dead zones caused by uneven water flow speed or distribution, thereby improving the sterilization effect of the drinking water.
[0027] The second embodiment of this application is as follows:
[0028] Please see Figure 2 Figure 4Based on the first embodiment, the drinking water sterilization device of this embodiment further includes an embedded frame 11 fixed at both ends of the inner wall of the primary sterilization box 3. An ultraviolet irradiation lamp 12 is fixed inside the two embedded frames 11. A controller 13 is fixed on the rear side of the primary sterilization box 3. The ultraviolet irradiation lamp 12 is electrically connected to the controller 13. By turning on the controller 13, the ultraviolet irradiation lamp 12 inside the embedded frame 11 is turned on to irradiate the drinking water flow. The two ultraviolet irradiation lamps 12 are arranged opposite each other to improve the irradiation sterilization efficiency of the drinking water flow.
[0029] A stirring rod 14 is rotatably connected to the inner side of the secondary sterilization box 5. Side rods 15 are fixedly arranged in an array outside the stirring rod 14. A motor 16 is fixed to the right side of the outer side of the secondary sterilization box 5, and the output end of the motor 16 extends into the interior of the secondary sterilization box 5 and is fixedly connected to the stirring rod 14 through a coupling. Hydrogen peroxide or sodium bicarbonate dilution solution is added into the secondary sterilization box 5 through the dispensing pipe 20. Then, the motor 16 is turned on, causing the stirring rod 14 to rotate with the multiple side rods 15, so that the sterilizing agent can come into contact with the drinking water flow to achieve the effect of secondary sterilization.
[0030] Both the primary sterilization box 3 and the secondary sterilization box 5 are equipped with a lid 17 on the top. A slot 18 runs through the top surface of the lid 17, and a card plate 19 is fixed inside the slot 18. The card plate 19 is transparent, which makes it easy to observe the sterilization status inside the primary sterilization box 3 and the secondary sterilization box 5. A dispensing tube 20 is fixed on the top right side of the secondary sterilization box 5. The bottom end of the dispensing tube 20 runs through the interior of the secondary sterilization box 5, and the dispensing tube 20 is angled to facilitate the dispensing of sterilizing agent into the secondary sterilization box 5. Both ends of the reflux pre-pipe 8 and reflux post-pipe 9 are fixed with retaining rings 21. The retaining rings 21 are circular in shape, which achieves the effect of fixing the reflux pre-pipe 8 and reflux post-pipe 9 to the outside.
[0031] The top of the water outlet pipe 7 is equipped with a water outlet valve 22, which makes it easy to open the water outlet valve 22 to facilitate the flow of drinking water. The interiors of the left frame 2 and the right frame 4 are both smooth to avoid wear on the outer bottom of the primary sterilization box 3 and the secondary sterilization box 5.
[0032] First, drinking water is introduced into the primary sterilization box 3 through the inlet pipe 6. At this time, the controller 13 is turned on, causing the ultraviolet irradiation lamp 12 inside the embedded frame 11 to irradiate the drinking water. The two ultraviolet irradiation lamps 12 are positioned opposite each other to improve the irradiation and sterilization efficiency of the drinking water, thus achieving primary sterilization of the drinking water. Next, the return valve 10 at the top of the return pipe 8 is opened to allow the drinking water from the primary sterilization box 3 to flow into the secondary sterilization box 5. At this time, hydrogen peroxide or sodium bicarbonate dilution solution is added into the secondary sterilization box 5 through the dispensing pipe 20. Next, the motor 16 is turned on, causing the stirring rod 14 to rotate along with the multiple side rods 15, so that the disinfectant can come into contact with the drinking water flow to achieve a secondary disinfection effect. Then, when it is necessary to improve the disinfection effect, the return valve 10 at the top of the return pipe 9 can be opened to allow the drinking water flow inside the secondary disinfection box 5 to flow back into the primary disinfection box 3. In this way, the drinking water flow is made to flow between the primary disinfection box 3 and the secondary disinfection box 5, so that the disinfection method can act on the water more evenly and avoid the situation of disinfection dead zones due to uneven water flow speed or distribution, thereby improving the disinfection effect of drinking water.
[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
