Description

Overflowing type UV LED diffuse reflection circulating sterilization device

Technical Field

The application relates to the field of water sterilization and disinfection and purification, in particular to an overflowing type UV LED diffuse reflection circulating sterilization device.

Background

Water is a source of life, and the quality of drinking water is increasingly poor along with the serious pollution of the environment. Most of water used in cities comes from water purification plants, but chemical substances such as bleaching agents, disinfection solutions and the like are used in the process of water purification, and certain chlorine or ammonia is left after the water purification. In the process of conveying tap water, the tap water can be used through the water outlet pressurization system and the plurality of water pipes, and iron water pipes are inevitably used for a long time to generate iron rust. Because the water storage system is difficult to clean and purify, the water storage system is usually cleaned once every quarter, and therefore escherichia coli, algae, bacteria and the like can grow.

In order to ensure the safety of drinking water, water purifiers are purchased by many families, and the water purifiers are simple in filtration, such as tap water purifiers which only rely on PP cotton, activated carbon, compressed carbon and the like and have lower cost; it is also preferable, for example, to filter tap water thoroughly through a reverse osmosis membrane, such as a water purification machine; and the ultrafiltration water purifier filters tap water through an ultrafiltration membrane to reach the standard of kitchen and drinking water. The water purifier is very effective in purifying water, but generally neglects the problem that bacteria grow after the water purifier is used for a long time. For example, the water purifier is provided with an activated carbon filter element for improving taste and adsorbing organic matters, but ignores the self-pollution problem of an activated carbon medium, and is like a super sponge, so that a large amount of toxic and harmful pollutants are adsorbed, the stay time is long, a large amount of bacteria can be propagated in micropores of the super sponge, and particularly, certain drinking water equipment is arranged in a shady, cool and humid place or a direct sunlight place, and the propagation speed of the bacteria is higher. The water outlet of the faucet and the activated carbon filter element are both used as a hotbed for bacterial reproduction, which can not only achieve the purpose of purifying water quality but also pollute the water quality. Therefore, ensuring the safety and health of drinking water is a problem to be solved urgently.

Optionally, referring to fig. 2, the overflowing type UV LED diffuse reflection circulation sterilization apparatus 100 provided in this embodiment further includes a fourth sealing ring 63; the light source heat sink 60 includes a fourth recess 64 therearound, and the fourth sealing ring 63 is located at the position of the fourth recess 64. Specifically, in this embodiment, the fourth recess 64 surrounding the light source heat sink 60 is disposed on the outer wall of the light source heat sink 60, and the fourth sealing ring 63 is disposed in the fourth recess 64, so as to prevent water from permeating through the outer wall of the light source heat sink 60, thereby avoiding the water leakage problem of the overflow type UV LED diffuse reflection circulation sterilization device 100, and facilitating the improvement of the use effect and the service life of the overflow type UV LED diffuse reflection circulation sterilization device 100. In addition to the first, second, third, and

fourth gaskets

36, 41, 52, and 63 provided in the above embodiment, gaskets may be provided in the nut 20, so that the problem of water leakage in the overflow UV LED diffuse reflection circulation sterilization apparatus 100 can be further prevented.

Alternatively, referring to fig. 1 and 2, the outer envelope 10, the UV diffuse reflection tube 50 and the quartz glass tube 40 are cylindrical in shape. Specifically, the shape of the quartz glass tube 40 is a hollow cylinder, and therefore, the quartz glass tube 40 is selected to be a common cylinder in this embodiment, so that the existing quartz glass tube 40 can be utilized, special manufacturing is not required, and cost reduction is facilitated, and meanwhile, the shapes of the shell 10 and the UV diffuse reflection tube 50 are also set to be cylindrical, so that the UV diffuse reflection tube 50 can be manufactured by using the existing manufacturing process, and the process is simple and is beneficial to reducing the manufacturing difficulty of the sterilization device 100. Of course, the shape of the outer shell 10, the UV diffuse reflection tube 50 and the quartz glass tube 40 is cylindrical, which is only one embodiment in this embodiment, and in other embodiments, the outer shell 10, the UV diffuse reflection tube 50 and the quartz glass tube 40 may be provided in other shapes, which is not limited in this application.

It should be noted that, in the present application, each component adopts a combination of multiple materials, wherein, the materials contacting the drinking water all adopt UV-resistant materials which are safe, environment-friendly and meet the standards of the drinking water; the light source heat sink 60 is made of metal; the quartz glass tube 40 is made of quartz glass environment-friendly material with high light transmittance; the housing 10 is made of high-strength plastic or metal.
