Description

Technical Field

[0001] The utility model relates to the technical field of water tank sterilization, in particular to an ultraviolet sterilization system for a water tank of direct drinking water equipment. Background Art

[0002] Direct drinking water equipment refers to equipment that filters water multiple times to reach the standard of being directly drinkable. Ultraviolet (UV) lamps are usually installed inside water tanks or on pipes through which water flows. These UV lamps emit ultraviolet light of a specific wavelength, usually 254 nanometers. This ultraviolet light has a strong bactericidal ability and can destroy the DNA structure of bacteria, viruses and other microorganisms, making them unable to reproduce and survive.

[0003] Existing ultraviolet disinfection does not produce toxicity, does not have any residues or various by-products, and does not change the taste, odor or pH value of water. However, it has no continuous sterilization ability. If the disinfected water encounters a new pollution source, it will be polluted again.

[0004] The existing patent (Announcement No.: CN204569626U) is a sterilization system for piped drinking water, which continuously sterilizes the drinking water in the drinking water storage tank, double-sterilizes the drinking water through a circulation pump and an ultraviolet sterilizer, and then returns the water to the drinking water storage tank to mix with the drinking water inside. The ozone dissolved in the water is widely dispersed throughout the water tank to sterilize the water therein. At the same time, the trace ozone dissipated in the water can also kill the air and inner wall of the water tank, inhibiting the growth of bacteria.

[0005] In view of the above problems, the existing patents provide solutions, but the sterilization efficiency is low during actual use. If it is directly applied to direct drinking water equipment, users will have to wait for a period of time before they can get direct drinking water, which is inconvenient to use.

[0006] Therefore, a direct drinking water equipment water tank ultraviolet sterilization system is proposed. Utility Model Content

[0039] By adopting the above technical solution, the problem that the ultraviolet sterilization system of the water tank of the existing direct drinking water equipment has low sterilization efficiency during actual use is solved. If it is directly applied to the direct drinking water equipment, it will cause the user to wait for a period of time before being able to receive direct drinking water, which is inconvenient to use.

[0040] When the present application is in use, firstly, a command is issued through the control panel 209 to make the filter 201 filter the water source connected to the outside, and then the first water pump 205 is started to drive the filtered water source to enter the water storage tank 203 through the first spiral tube 204. When the water flows inside the first spiral tube 204, the flow sensor 208 is triggered. Through the flow sensor 208, the first controller 206 starts the first ultraviolet sterilization lamp 207. The ultraviolet rays emitted by the first ultraviolet sterilization lamp 207 pass through the first spiral tube 204 made of quartz to disinfect and sterilize the water source inside the first spiral tube 204. At the same time, since the first spiral tube 204 is a spiral design, the water source can be sterilized by ultraviolet rays to the greatest extent. Then, when water needs to be discharged, the controller 206 starts the first ultraviolet sterilization lamp 207. The second water pump 301 is driven to drive the water source inside the water tank 203 to discharge through the second spiral tube 303 and the water outlet 307 through the water suction pipe 302.
