Description

Technical Field

[0001] The utility model relates to the field of flowing water sterilization, in particular to a flowing water UVC sterilization component, a component and a water purification device. Background Art

[0002] For the existing flowing water UVC sterilization component, to achieve the sterilization rate index of 99.99%, in addition to increasing the UVC sterilization power, it is also necessary to improve the light utilization rate of UVC from the product structure, so as to realize the uniform distribution of the UVC irradiation intensity in the whole flowing water cavity, so as to meet the requirement of instant sterilization of flowing water. To improve the light utilization rate of UVC, a reflection cavity structure is usually made of high-reflection materials by machining, and the tube wall is polished by machining to improve the reflectivity. However, there are still surface capillary rough surfaces on its surface. After long-term use, substances in the water will gradually precipitate and adhere to the surface of the tube wall. The decrease in the reflectivity of the precipitation area will reduce the UVC reflection effect, resulting in a decrease in the sterilization ability. Moreover, the cost of such materials is high, the machining cost is high and the efficiency is low. The above points restrict the popularization and application of the flowing water UVC sterilization component in the terminal market.

[0003] In addition, restricted by the existing structural design, the UVC light source is placed on one side of the reflection cavity, and the light is projected from one side into the whole cavity. Although the cavity wall has a reflection effect, it is still necessary to increase the radiation power of the UVC light source to meet the energy distribution in the whole cavity; and both sides of the reflection cavity are also the in / out channels for flowing water, resulting in a narrow space in this area. It is necessary to concentrate the UVC light source distribution. Therefore, the heat dissipation power of the UVC LED lamp beads / chips per unit area is too large, and a heat dissipation design needs to be made with copper parts. It is also necessary to place the copper parts in the flowing water channel for water cooling; the assembly process is cumbersome and the cost is high. Summary of the Utility Model
