Description

Technical Field

[0001] This utility model relates to the field of drinking water preparation technology, and in particular to a circulating ultraviolet low-temperature sterilization drinking water preparation device. Background Technology

[0002] The safety and hygiene of drinking water are crucial to people's health, and sterilization is a key step in the drinking water preparation process. Currently, commonly used methods for drinking water sterilization include high-temperature sterilization and chemical sterilization. High-temperature sterilization requires a large amount of energy to heat the water to a certain temperature, which is not only energy-intensive but may also alter the taste and nutritional composition of the water. While chemical sterilization is relatively simple to operate, it is easy for chemical residues to remain in the water, posing potential risks to human health.

[0003] Ultraviolet (UV) sterilization, as a physical sterilization method, has advantages such as high efficiency, no residue, and simple operation, and has been widely used in drinking water treatment. However, most existing UV sterilization drinking water preparation devices are single-pass sterilization devices, where water is discharged after only one UV irradiation. For some heavily polluted water sources, this may not achieve the desired sterilization effect, resulting in incomplete sterilization and affecting the safety of drinking water. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circulating ultraviolet low-temperature sterilization drinking water preparation device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a circulating ultraviolet low-temperature sterilization drinking water preparation device, comprising a sterilization component, which is composed of a sterilization tube and a top cover, and further comprising:

[0006] The rotating frame assembly consists of an annular frame disposed between the sterilization tube and the top cover. The annular frame is provided with a support frame. There are three support frames in total, and the three support frames are arranged in a ring. The distance between two adjacent support frames is equal. The bottom of the support frame is provided with a tripod sliding frame.

[0007] Furthermore, the tripod sliding frame is provided with a sliding block, and the tripod sliding frame is slidably connected to the ring frame through the sliding block.

[0008] The beneficial effects of adopting the above-mentioned further solution are as follows: the tripod sliding frame is slidably connected to the ring frame by means of sliding blocks, which can drive the rotating sterilization component to move flexibly along the ring frame, expand the coverage of ultraviolet irradiation, and allow all areas of the water body to be fully treated by sterilization. This sliding structure allows the sterilization component to adapt to different water flow conditions, improve the uniformity of sterilization, avoid incomplete sterilization in some areas, and at the same time, the sliding connection method reduces the wear and tear of components, enhances the stability and durability of the device, and helps to efficiently complete the cyclic sterilization process.

[0009] Furthermore, a drive motor is provided on the support frame, and the output end of the drive motor passes through the support frame and is connected to the tripod sliding frame. A rotating sterilization component is provided on the tripod sliding frame. There are three rotating sterilization components in total, and the included angle between two adjacent rotating sterilization components is equal.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: the drive motor on the support frame provides power to the tripod sliding frame, driving it to slide stably, thereby causing the rotating sterilization components to move accordingly. The three rotating sterilization components, which are distributed at equal angles, can form a comprehensive sterilization coverage during movement, reducing sterilization blind spots. The motor drive ensures a stable sliding rhythm. Combined with the uniform distribution of the components, it allows all parts of the water to be irradiated by ultraviolet light more evenly, improving the overall sterilization effect. At the same time, the structural design makes the power transmission efficient, enhancing the coordination and reliability of the device operation.

[0011] Furthermore, the rotary sterilization component consists of a bearing shaft located at the bottom of a tripod sliding frame. A mounting bracket is provided at the bottom of the bearing shaft, and a rotating rod is rotatably connected to the bottom of the mounting bracket. Both ends of the rotating rod are equipped with ultraviolet lamps.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: The rotating sterilization component is connected to the tripod sliding frame through the bearing shaft, and the bottom mounting frame drives the rotating rod to rotate, so that the ultraviolet lamps at both ends can flexibly adjust the irradiation angle. The bearing shaft ensures smooth rotation of the component, and the rotation of the rotating rod allows the ultraviolet lamps to cover more water areas and avoid irradiation dead spots. This structure enables the ultraviolet lamps to achieve multi-angle sterilization while moving, improves the contact efficiency with the water, enhances the comprehensiveness and depth of sterilization, ensures that all parts of the water can be effectively irradiated, and helps to improve the overall sterilization effect.

[0013] Furthermore, a micro motor is provided between the mounting bracket and the bearing shaft, and the output end of the micro motor is connected to the rotating rod.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the micro motor between the mounting bracket and the bearing shaft provides power to the rotating rod, driving it to rotate stably and continuously adjusting the irradiation direction of the ultraviolet lamps at both ends. The motor drive ensures a uniform rotation rhythm, allowing the ultraviolet lamps to fully sweep the surrounding water body and avoid irradiation blind spots caused by fixed angles. This design enhances the full contact between ultraviolet light and water body, improving the fineness and thoroughness of sterilization. At the same time, the micro motor has low energy consumption, and together with the overall structure, it makes the device operate more efficiently and coordinately.

[0015] Furthermore, a sterilizing cotton partition is provided inside the sterilization tube, and a through hole is opened on the sterilizing cotton partition. Connecting pipes are fixedly connected to both sides of the sterilization tube.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the blister and perforated structure of the blister cotton inside the blister tube can buffer and disperse the water flow, prolonging the water's residence time in the tube and forming turbulence, increasing the chance of contact with ultraviolet light. The blister cotton can also intercept some impurities, improving water quality while preventing it from blocking the ultraviolet lamp. The connecting pipes on both sides ensure smooth water circulation, allowing the inlet and outlet water to form an orderly flow path, ensuring that all parts of the water can fully pass through the blister area, enhancing the overall blister effect and treatment efficiency.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] In this invention, the sterilization tube and the top cover are connected by the ring frame of the rotating frame assembly, providing stable support for the overall structure. The three equally spaced ring-shaped support frames, together with the bottom tripod sliding frame, form a balanced force structure, ensuring stability during sliding. This layout allows the rotating sterilization component to be evenly distributed along the ring trajectory, covering more areas inside the sterilization tube, reducing irradiation dead zones, making the water body more evenly irradiated by ultraviolet light, improving the comprehensiveness and reliability of sterilization, and enhancing the overall coordination of the device during operation.

The drive motor 211 on the support frame 22 provides power to the tripod sliding frame 23, driving it to slide stably, thereby causing the rotating sterilization components 3 to move accordingly. The three rotating sterilization components 3, which are distributed at equal included angles, can form a comprehensive sterilization coverage during movement, reducing sterilization blind spots.
