Abstract
Description
Technical Field
[0001] This utility model relates to a sterilization device, specifically a self-generating faucet ultraviolet sterilization device. Background Technology
[0002] Currently, as people pay increasing attention to the safety of drinking water, more and more families are choosing faucets or water treatment equipment with sterilization functions to reduce the potential harm of bacteria in the water to human health. Among them, ultraviolet sterilization, as a highly efficient and rapid physical sterilization method, is widely used in water purification systems in homes, medical facilities, laboratories, and other fields because it does not produce harmful byproducts and can kill bacteria, viruses, and other microorganisms in the water without changing its chemical properties.
[0003] However, existing ultraviolet sterilization devices generally suffer from the following problems: First, most ultraviolet sterilization devices rely on external power sources, such as sockets or batteries, which not only limits the application scenarios and installation locations of the products, but also increases energy consumption and maintenance costs; Second, some small household ultraviolet sterilization devices are limited by size, resulting in low sterilization light power, low sterilization efficiency, and problems such as light dispersion and limited effective range; Third, some products have complex structures or are bulky, making the installation process cumbersome and inconvenient for users to disassemble and clean themselves, thus affecting the user experience.
[0004] Furthermore, existing devices often lack effective light focusing and reflection designs in terms of ultraviolet (UV) efficiency, leading to UV scattering within the chamber and further reducing sterilization efficiency. If the UV light emitted cannot be concentrated on key areas of the water, the desired sterilization effect cannot be achieved. Summary of the Invention
[0005] To address the aforementioned problems, this utility model provides a self-generating faucet ultraviolet sterilization device that generates its own electricity using tap water pressure, does not rely on an external power source, has a compact structure, is easy to install, has high sterilization efficiency, and is easy to clean and maintain. This solves the problems existing in the prior art.
[0006] This utility model is achieved through the following technical solution: a self-generating water tap ultraviolet sterilization device, comprising:
[0007] The housing has a water inlet at one end and a water outlet at the other end, with the water inlet connected to the water outlet of a faucet.
[0008] A self-generating mechanism is installed inside the housing, with the drive end of the self-generating mechanism facing the water inlet end of the housing. The water pressure at the water inlet end drives the self-generating mechanism to generate electricity.
[0009] An ultraviolet sterilization mechanism is installed inside the housing and located at the outer end of the self-generating mechanism. It is used to generate ultraviolet sterilization light and focus it onto the water inlet of the housing.

[0011] As a preferred technical solution, the ultraviolet sterilization mechanism includes one or more UVC lamp beads, which are installed on the outer surface of the generator. The output of the generator is rectified by a rectifier module and supplied to the UVC lamp beads.
[0012] As a preferred technical solution, the ultraviolet sterilization mechanism further includes a first quartz glass sleeve, a second quartz glass sleeve, and a reflective film.

[0018] As a preferred technical solution, the housing includes a light guide ring, an upper shell, and a lower shell, wherein the upper shell and the lower shell are threadedly installed at the upper and lower ends of the light guide ring.
[0019] The beneficial effects of this utility model are: This utility model generates electrical energy by driving the internal self-generating mechanism through water pressure to power the ultraviolet germicidal lamp, without the need for an external power supply or built-in battery, which is energy-saving and environmentally friendly, and improves the flexibility and safety of the product.
[0020] The device uses UVC band ultraviolet lamp beads for sterilization and constructs a sealed sterilization chamber through a quartz glass sleeve and an internal reflective film, which effectively reflects and focuses ultraviolet light to the water inlet, greatly improving the sterilization efficiency of ultraviolet light. Experimental results show that the sterilization rate of bacteria in the flowing water can reach 99.99%. Attached Figure Description

[0026] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0027] 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.
[0028] like Figures 1-2 As shown, this utility model provides a self-generating faucet ultraviolet sterilization device, aiming to achieve efficient water sterilization without external power supply, improving ease of use and sterilization efficiency. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0029] The self-generating faucet UV sterilization device mainly includes a housing, a self-generating mechanism, and a UV sterilization mechanism. The housing has a cylindrical structure with an inlet at one end and an outlet at the other. The inlet connects to the outlet of a household faucet and is compatible with most standard faucet interfaces. To improve the flexibility and sealing of the connection between the device and the faucet, a universal adapter 1 is installed at the inlet. This adapter connects to the housing via threads and has a waterproof filter screen 14 on its inner side, effectively preventing larger particles from entering the housing and providing primary filtration and protection for the internal structure.
[0030] Inside the housing, a self-generating mechanism and an ultraviolet sterilization mechanism are arranged sequentially along the water flow direction. The self-generating mechanism is preferably installed near the water inlet of the housing, with its drive end facing the water inlet direction. When water enters the water inlet from the faucet, the water pressure impacts the turbine blades 7 inside the self-generating mechanism, causing them to rotate and thus driving the generator 8 to generate electricity. The output end of the generator 8 is connected to the ultraviolet sterilization mechanism to power the sterilization device, avoiding the use of batteries or external power sources and improving environmental friendliness and safety.
[0031] Specifically, the generator 8 in the self-generating mechanism has a compact structure, and its drive end is equipped with multiple turbine blades 7. These blades have good hydrodynamic response performance, enabling high-speed output under low water pressure and improving power generation efficiency. The power output end of the generator 8 is connected to the input end of the ultraviolet sterilization mechanism. Before the current is output, it is rectified by a rectifier module to ensure a stable power supply to the ultraviolet sterilization lamp beads, ensuring a continuous and stable sterilization effect.
[0032] An ultraviolet (UV) sterilization mechanism is located on the outer end of the generator 8, facing the water inlet, and is used to emit UV sterilization beams. The UV sterilization mechanism includes at least one UVC lamp bead 9, preferably multiple bead beads, to enhance the overall sterilization intensity. The lamp bead is mounted on the outer surface of the generator 8, and as water flows through it, it directly irradiates the area through which the ultraviolet light passes, effectively killing bacteria and viruses in the water.
[0033] To improve the utilization efficiency of ultraviolet light and avoid light waste, the ultraviolet sterilization mechanism is also equipped with a first quartz glass sleeve 10, a second quartz glass sleeve 11, and a reflective film 12. The first quartz glass sleeve 10 is installed on the outside of the generator 8, serving as the first sealing and protective layer for the UVC lamp beads 9. This quartz sleeve has high transparency and strong resistance to ultraviolet radiation, effectively isolating water flow and preventing damage to the lamp beads from contact with water. At the same time, first O-rings 15 are respectively provided above and below the UVC lamp beads 9 to fit with the first quartz glass sleeve 10, improving the sealing performance and preventing moisture from entering the lamp bead cavity.
[0034] The second quartz glass sleeve 11 is fixedly installed on the inner wall of the housing, covering the outside of the first quartz glass sleeve 10, forming a double-layer isolation and protection structure. This structural design not only improves the overall sealing strength but also provides installation space to accommodate the reflective film 12. The reflective film 12 is fixed in the gap between the second quartz glass sleeve 11 and the housing. Its material has a high ultraviolet reflectivity, which can reflect and focus unabsorbed ultraviolet rays to the water inlet position, increasing the irradiation density of ultraviolet rays in the key sterilization area, thereby achieving higher sterilization efficiency. The reflective film 12 can be installed at an angle to achieve the purpose of reflection and focusing.
[0035] To ensure tight assembly of all components, the bottom of the generator 8 engages with the internal threads on the inner side of the housing via an external thread structure, making installation simple and reliable, and facilitating subsequent disassembly, cleaning, and maintenance. A water outlet 5 is provided at the water outlet end, and a water-saving device 6 is installed inside the water outlet 5 to regulate the water flow and improve water usage efficiency. A second O-ring 13 is provided at the connection between the water outlet 5 and the housing to prevent leakage at the connection and ensure reliable sealing during long-term use.
[0036] The housing consists of a light guide ring 3, an upper shell 2, and a lower shell 4. The upper shell 2 and the lower shell 4 are connected to the upper and lower ends of the light guide ring 3 by threads, respectively. The light guide ring 3 can be made of plastic or glass with certain light transmittance and UV resistance. It not only serves as a structural connection but also helps to guide some light out in conjunction with the internal UV lamp beads, making it easier for users to intuitively judge whether the device is in working condition, further improving the product's ease of use and intelligent prompting function.
[0037] This invention provides a compact, non-external power supply-required, highly efficient, adaptable, easy-to-install, and easy-to-clean UV sterilization device for faucets, which is particularly suitable for daily water use scenarios such as kitchens and bathrooms in homes and has good practical and promotional value.
[0038] 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.
