Description

Technical Field

[0001] This utility model relates to the field of water purifiers, and in particular to a water purifier with an ultraviolet sterilization device. Background Technology

[0002] A water purifier with ultraviolet (UV) sterilization is an advanced household water purification device that uses UV lamps to emit ultraviolet light to kill bacteria, viruses, and other microorganisms in the water. These purifiers typically include a multi-stage filtration system, such as a pre-filter, activated carbon filter, and reverse osmosis membrane, to remove impurities, chlorine, heavy metals, and organic matter from the water. UV sterilization technology is a physical disinfection method that does not chemically pollute the water or alter its taste or odor. Using this type of water purifier ensures safe and hygienic drinking water and is particularly suitable for homes, offices, or public places.

[0003] Most water purifiers on the market are equipped with ultraviolet (UV) sterilization devices. These devices work by inserting UV lamps into a sterilization tank, using ultraviolet light to disinfect the flowing water. However, in practical applications, if the liquid flow rate is too fast, the water may not stay in the sterilization tank long enough, thus affecting the UV's effectiveness in killing microorganisms. In this case, even if the water passes through the UV lamp, it may not receive sufficient irradiation, resulting in a reduced sterilization effect. Utility Model Content

The inlet pipe 4 and the outlet pipe 6 are connected to both ends of the multi-stage filtration assembly 5, allowing the water treated by the multi-stage filtration assembly 5 to be discharged smoothly.

[0025] In addition, the frame 1 is connected to the sterilization tank 7 via brackets, bolts, nuts, and other connectors. The upper end of the sterilization tank 7 is connected to the drain pipe 6 to ensure that filtered water can flow into the sterilization tank 7. A drain pipe 8 is provided on the lower side wall of the sterilization tank 7 to discharge the sterilized water. A sealing cap 9 is installed at the lower end of the sterilization tank 7, and an ultraviolet lamp holder 12 is installed at the lower end of the sealing cap 9. An ultraviolet lamp tube 13 is connected to the upper end of the ultraviolet lamp holder 12. This lamp tube is inserted into the sterilization tank 7, and the water inside the tank is sterilized by ultraviolet irradiation.

[0026] The inner end of the sealing cap 9 is equipped with a fixing seat 10, and the side wall of the fixing seat 10 has a liquid outlet 11, which is directly opposite the liquid outlet pipe 8 to ensure that the disinfected water can flow out smoothly. The upper end of the fixing seat 10 is connected to the assembly cover 14 through a screw tube 15. Multiple assembly covers 14 are connected together by screw tubes 15 to form a whole structure. The ultraviolet lamp tube 13 is inserted into the opening at the lower end of the assembly cover 14. By reducing the orifice diameter, the liquid flow rate is slowed down, thereby increasing the time that the water is exposed to ultraviolet light and improving the disinfection and sterilization effect.

[0027] The drain pipe 6 is fixed to the upper pipe of the sterilization tank 7 using a connecting flange, bolts, and nuts. A sealing ring is provided between the two to ensure the connection is airtight.
