Description

Technical Field

[0001] This utility model relates to a sterilization device, specifically a high-efficiency ultraviolet sterilization device. Background Technology

[0002] Currently, ultraviolet (UV) sterilization technology is widely used in water treatment systems, especially in household water purifiers, medical and health care, and food processing. It destroys bacteria, viruses, and other microorganisms through physical means, offering advantages such as no chemical residue, rapid sterilization, and high efficiency. In common UV sterilization devices, an external power supply typically powers the UV light source, and a quartz tube is used as the UV light propagation medium, allowing the water flowing through the device to be irradiated with ultraviolet light to achieve sterilization.

[0003] However, existing technologies still have the following shortcomings: On the one hand, current ultraviolet sterilization devices generally rely on external power sources or batteries, which not only limits the flexibility of their installation location but also increases usage costs and maintenance complexity. On the other hand, to achieve efficient sterilization, it is often necessary to extend the contact time between the water and ultraviolet light. However, in traditional straight-pipe structures, the water flow velocity is relatively fast and the flow path is relatively short, resulting in insufficient ultraviolet irradiation time and thus reducing the sterilization effect. In addition, some ultraviolet sterilization devices fail to effectively improve the utilization rate of ultraviolet light in their structure, resulting in the problem of wasted light energy. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a highly efficient ultraviolet sterilization device that requires no external power supply, extends the irradiation path in water, and improves the utilization efficiency of ultraviolet light. This enhances sterilization performance, reduces energy consumption, and increases the adaptability and convenience of the device in various scenarios.

[0007] The first ultraviolet sterilization device is installed on the water inlet side of the sleeve and generates electricity through the first power generation device.

[0008] The second ultraviolet sterilization device is installed on the water outlet side of the sleeve and generates electricity through the second power generation device.

[0009] A conical quartz tube is installed inside the sleeve. The large-diameter end of the conical quartz tube is located at the water inlet end of the sleeve, and the small-diameter end of the conical quartz tube is located at the water outlet end of the sleeve. The first ultraviolet sterilization device and the second ultraviolet sterilization device are both installed outside the conical quartz tube and are used to sterilize the water passing through the conical quartz tube with ultraviolet light.

[0010] A reflective film, installed on the inner wall of the sleeve, is used to reflect ultraviolet light onto the conical quartz tube and to sterilize the water flowing through the conical quartz tube with ultraviolet light.

[0011] As a preferred technical solution, a fan-shaped rotating component is also included, which is installed at the water inlet end of the sleeve. The fan-shaped rotating component is provided with fan blades. After the water flows through the fan-shaped rotating component, it forms a swirling flow and enters the conical quartz tube.

[0012] As a preferred technical solution, a water-passing adapter is provided at the outer end of the fan-shaped rotating component. The water-passing adapter is threadedly assembled with the sleeve, and an O-ring is provided on the threaded assembly surface. The large-diameter end of the tapered quartz tube is connected to the water outlet end of the fan-shaped rotating component, and a water inlet adapter is installed on the external thread of the water-passing adapter.

[0013] As a preferred technical solution, the water inlet end of the water inlet adapter is threadedly connected to the first power generation device, the water inlet end of the first power generation device is connected to a faucet, and the first power generation device is driven to generate electricity by water pressure. A first 4-point waterproof gasket is provided on the threaded connection side of the first power generation device and the water inlet adapter.

[0014] As a preferred technical solution, a fixed adapter is fixedly provided at the water outlet end of the sleeve. One end of the fixed adapter is fixedly installed inside the sleeve, and the other end extends out of the sleeve and is threadedly connected to a water outlet adapter.

[0015] As a preferred technical solution, a silicone waterproof sleeve is sealed between the fixed adapter and the tapered quartz tube, and the second ultraviolet sterilization device is fitted to the fixed adapter.

[0016] As a preferred technical solution, one end of the water outlet adapter is threaded to the second power generation device, and a second 4-point waterproof gasket is installed between the second power generation device and the water outlet adapter.

[0017] As a preferred technical solution, the first ultraviolet sterilization device includes a first UVC lamp plate, which is annular with a first positioning hole in the middle, and one end of the conical quartz tube passes through the first positioning hole.

[0018] As a preferred technical solution, the second ultraviolet sterilization device includes a second UVC lamp plate, which is annular with a second positioning hole in the middle, and the other end of the conical quartz tube passes through the second positioning hole.

[0019] The beneficial effects of this utility model are: This utility model is equipped with a first power generation device and a second power generation device at the water inlet and water outlet respectively. Both devices generate electricity through water flow to supply the two sets of ultraviolet sterilization devices. This realizes a green and environmentally friendly sterilization solution that is powered entirely by water pressure, reducing energy consumption and improving the flexibility of use.

[0020] This utility model is equipped with ultraviolet sterilization devices at both the water inlet and outlet positions. Through the front and rear UVC lamp panels, ultraviolet irradiation is carried out, which effectively extends the cumulative irradiation time of the water under the sterilization light source, enhances the sterilization effect, and achieves dual protection.

[0021] This invention features a conical quartz tube inside the device, with its larger diameter facing the water inlet and its smaller diameter facing the water outlet. This forces the water to flow through a gradually narrowing channel, extending the water's residence time in the ultraviolet irradiation area and facilitating more thorough sterilization.

[0022] This invention features an ultraviolet reflective film on the inner wall of the sleeve, which effectively reflects and focuses ultraviolet light onto the quartz tube and its internal water, enabling multiple ultraviolet irradiations and significantly improving the utilization rate of ultraviolet light and overall sterilization efficiency.

[0023] The water inlet of this invention is equipped with a fan-shaped rotating component with internal fan blades, which can guide the straight water flow into a rotating water flow, so that the water flow forms a vortex-like flow trajectory in the conical quartz tube, thereby extending the path length and residence time of the water in the tube and further improving the sterilization efficiency.

[0032] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0033] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0034] like Figures 1-5 As shown, this utility model discloses a high-efficiency ultraviolet sterilization device that utilizes water flow to efficiently disinfect water through ultraviolet sterilization technology. The device has a simple structural design and an efficient water flow utilization method, enabling it to generate its own electricity and optimize the ultraviolet sterilization effect.

[0035] like Figure 1 and Figure 2 As shown, the device includes a sleeve 15, with a first power generation device 1 and a second power generation device 14 installed at the inlet and outlet ends of the sleeve 15, respectively. Water flows through these power generation devices, providing power to the first and second ultraviolet sterilization devices. In this way, the device achieves the function of generating electricity through water flow to power the ultraviolet sterilization devices without relying on an external power source, ensuring efficient and environmentally friendly operation.

[0036] A tapered quartz tube 8 is installed inside the sleeve 15. The large-diameter end of the tapered quartz tube 8 is located at the water inlet end of the sleeve 15, and the small-diameter end is located at the water outlet end of the sleeve 15.

[0037] The design of the conical quartz tube 8 effectively prolongs the residence time of water within the tube, increasing the contact time between the water and ultraviolet light, thereby enhancing the sterilization effect. The first and second ultraviolet sterilization devices are respectively installed on the outside of the conical quartz tube 8. These two sets of ultraviolet sterilization devices are powered by a generator and directly sterilize the water passing through the conical quartz tube 8. This dual ultraviolet irradiation further enhances the sterilization effect, ensuring that the water is effectively disinfected after passing through two stages of ultraviolet irradiation.

[0038] In addition, a reflective film 16 is installed on the inner wall of the sleeve 15. The reflective film 16 can reflect ultraviolet light back to the conical quartz tube 8 and perform ultraviolet sterilization on the water flow again.

[0039] In this way, with the assistance of the reflective film 16, ultraviolet light is utilized more effectively, so that the water is irradiated with ultraviolet light multiple times when it flows through the pipe, thereby improving the utilization efficiency of ultraviolet light and the sterilization effect of water.

[0040] To optimize the water flow path and increase the contact time between water and ultraviolet light, this implementation scheme also includes a fan-shaped rotating component 5, which is installed at the water inlet end of the sleeve 15.

[0041] The fan-shaped rotating component 5 is equipped with fan blades. When water flows through this rotating component, the water flow forms a vortex and enters the conical quartz tube 8. The formation of the vortex not only increases the residence time of the water in the conical quartz tube 8, but also changes the flow trajectory of the water, allowing the water to be better irradiated by ultraviolet light, thereby improving the sterilization efficiency.

[0042] After the water flows through the inlet end of the sleeve 15, the water-transfer adapter 6 is threadedly assembled with the sleeve 15, and an O-ring waterproof ring 4 is provided on the threaded assembly surface to ensure the sealing performance of the device.

[0043] Meanwhile, the external thread of the water transfer adapter 6 is fitted with a water inlet adapter 3, which is connected to the first power generation device 1 via a thread. The first power generation device 1 generates electricity through water flow to provide the necessary power for the ultraviolet sterilization device.

[0044] A first 4-point waterproof gasket 2 is installed between the water inlet adapter 3 and the first power generation device 1 to ensure the sealing of the connection and prevent water leakage.

[0045] At the outlet end of the sleeve 15, a fixed adapter 10 is installed inside the sleeve 15 and connected to the outlet adapter 12 by threads. A silicone waterproof sleeve 11 is provided between the fixed adapter 10 and the tapered quartz tube 8 to ensure that water does not leak from the connection.

[0046] In addition, the second ultraviolet sterilization device is set close to the fixed adapter 10, and is consistent with the path that the water flows through at the outlet end, so as to ensure that the water can be fully sterilized by ultraviolet light when it flows through this area.

[0047] One end of the water outlet adapter 12 is connected to the second power generation device 14 via a thread. The second power generation device 14 also generates electricity through water flow, providing power to the second ultraviolet sterilization device. To ensure the stability and waterproofness of the power connection, a second 4-point waterproof gasket 13 is installed between the water outlet adapter 12 and the second power generation device 14.

[0048] like Figures 3-5 As shown, the first ultraviolet sterilization device includes an annular first UVC lamp plate 7, with a first positioning hole in the middle of the first UVC lamp plate 7. One end of a conical quartz tube 8 passes through the positioning hole, so that the lamp plate can be accurately positioned outside the conical quartz tube 8, ensuring that ultraviolet rays can be concentrated on the water passing through the pipe.

[0049] Similarly, the second ultraviolet sterilization device also includes a ring-shaped second UVC lamp plate 9. The second UVC lamp plate 9 has a second positioning hole in the middle. The other end of the conical quartz tube 8 is connected through this hole, so that the second UVC lamp plate 9 can be docked with the conical quartz tube 8 to ensure efficient transmission and irradiation of ultraviolet light.

[0050] This high-efficiency ultraviolet sterilization device not only achieves the environmentally friendly characteristic of water-driven power generation, but also greatly improves the sterilization efficiency of ultraviolet light through the combination of ultraviolet irradiation and reflective film 16. The swirling water flow design further enhances the water residence time, ensuring sufficient ultraviolet irradiation, thereby improving the overall sterilization effect.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
