[0002] With the improvement of people's living standards and the enhancement of health awareness, the safety and hygiene of drinking water are receiving increasing attention. While traditional water dispensers provide convenient drinking water services, they have certain limitations in water sterilization. For example, conventional water dispensers mostly use physical filtration or chemical sterilization methods, which may not effectively kill all microorganisms in the water, and chemical disinfectant residues may pose potential risks to human health. Furthermore, after long-term use, bacteria and viruses can easily grow in the water tank inside the dispenser, further affecting water quality safety.
[0003] To address the aforementioned issues, some water dispensers with ultraviolet (UV) sterilization functions have emerged on the market. However, existing UV sterilization water dispensers still have design shortcomings, such as improper UV lamp placement leading to uneven UV radiation, or insufficiently tight connection between the UV lamp and the water tank, affecting the sterilization effect. Therefore, developing a more rationally designed water dispenser spout structure with better sterilization performance is particularly important. Clearly, existing technology still needs improvement and enhancement. Utility Model Content

[0031] This utility model provides a water outlet structure for a water dispenser. To make the purpose, technical solution and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments.
[0032] In the description of this utility model, it should be understood that the terms "up, down, left, right" and other indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation" and "connection" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] Please see Figures 1 to 4 This utility model provides a water outlet structure for a water dispenser, comprising a housing 1, a UV sterilization water tank 2, and a UV sterilization lamp 3. The housing 1 is injection molded from food-grade ABS engineering plastic, forming a cylindrical cavity with a diameter of 120-150mm inside, and a maintenance cover with a threaded connection at the top. The UV sterilization water tank 2 is coaxially suspended within the cavity by four sets of silicone shock-absorbing pads. Its bottom has a water inlet 4 with a check valve, and a 15mm diameter water outlet hole is opened on the upper side wall 30mm from the top. Optionally, the axis of the water outlet 5 is flush with the horizontal plane or at a 15° angle. The UV sterilization lamp 3 is a 265nm wavelength UVC-LED module, vertically fixed to the central mounting base at the top of the UV sterilization water tank 2, and connected to the control circuit board on the outside of the housing 1 via a waterproof cable.
[0034] Preferably, the front side of the outer casing 1 is provided with a water inlet assembly, which includes a main water outlet 6, a first vent 7, and a second vent 8. The main water outlet 6 has an inner diameter of 8mm and is directly connected to the water outlet interface 5. The water outlet end of the main water outlet 6 protrudes 20mm from the lower surface of the outer casing 1. The first vent 7 and the second vent 8 are respectively made of 304 stainless steel pipes with diameters of 4mm and 3mm, arranged concentrically around the main water outlet 6, with a distance of 2mm between them. The end faces of the pipes are polished to form an arc transition. It can be understood that the first vent 7 and the second vent 8 work together to release air in time when the drinking water boils, ensuring stable water output and compatibility with the true boiling function of the water dispenser.
[0035] Furthermore, the first exhaust nozzle 7 is connected to an upwardly extending first exhaust pipe 9, the top opening of which is 35mm from the top inner wall of the outer casing 1; the top opening of the second exhaust pipe 10 is 5mm from the top inner wall. Both the first exhaust pipe 9 and the second exhaust pipe 10 are made of PC material, and anti-siphon air holes are provided on the pipe wall at 50mm intervals. The center line of the water outlet is located between the two top openings, forming a stepped airflow channel with a height difference of 15mm.
[0036] The PCB board 11 is fixed to the heat dissipation area on the upper surface of the housing 1 by clips, and a lamp holder with overload protection is soldered to its center. The electrodes of the UV germicidal lamp 3 are connected to the lamp holder through quick-connect connectors. The PCB board 11 integrates a light intensity sensor and a timing module, which can monitor the ultraviolet irradiation intensity in real time and accumulate the sterilization time.
[0037] The UV sterilization water tank 2 has a quartz glass partition 12 at the top, with fluororubber sealing rings 13 embedded on both the upper and lower ends of the partition 12, forming a double-sealing structure with the mounting base. The inner wall of the UV sterilization water tank 2 is coated with a 304 stainless steel reflective layer with a nano-silver coating, which has a reflectivity of ≥85%, allowing ultraviolet rays to be reflected and refracted multiple times inside the UV sterilization water tank 2. A porous flow stabilizing mesh 14 with a 2mm aperture is provided at the bottom, and the surface of the porous flow stabilizing mesh 14 has water inlet micropores arranged in a honeycomb pattern.
[0038] The working principle of the water outlet structure of this utility model is as follows: After the water to be treated enters the UV sterilization water tank 2 through the water inlet, it forms a laminar flow under the action of the flow stabilizing net. The ultraviolet rays emitted by the UV sterilization lamp 3 form multiple reflection paths through the reflective layer, sterilizing the water source of the UV sterilization water tank 2. When water is drawn, the water flows out through the main water outlet 6, and at the same time, the first and second exhaust pipes 10 form a gradient negative pressure through the height difference, effectively eliminating the water hammer phenomenon. When the cumulative sterilization time reaches the set threshold, the control circuit automatically triggers an alarm to prompt maintenance.
[0039] In summary, the water outlet structure of this utility model for a water dispenser features a UV sterilization water tank 2 coaxially housed within the outer casing 1. The bottom water inlet 4 is designed to be aligned with the water outlet 5 near the top of the side wall, ensuring a scientific water flow path and facilitating full UV irradiation of the water. This effectively kills bacteria and viruses, guaranteeing water quality safety. The UV sterilization lamp 3, located at the center of the top of the water tank, emits ultraviolet light that penetrates the water evenly, sterilizing without blind spots. Furthermore, its connection design with the external control circuit facilitates user operation and ensures precise control and efficient operation of the sterilization process. This structure not only simplifies installation and maintenance but also significantly improves the hygiene standards of the water dispenser, providing users with a healthier and more convenient drinking experience. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.
[0040] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
