Laminar flow type UVC module

Abstract

The invention discloses a laminar flow type UVC module, and the module comprises a top cover provided with a water inlet and a water outlet; a heat dissipation shell is connected to the lower portionof the top cover in a sealed mode, a light reflection sleeve is arranged on the surface of the inner wall of the lower portion of the heat dissipation shell, and a light reflection pipe communicated with the water inlet is arranged in the middle of the interior of the heat dissipation shell; a horizontal baffle part extends from the position, close to the middle, of the reflective tube in the peripheral direction, a gap allowing water to flow through is reserved between the baffle part and the reflective sleeve, the baffle part, the reflective tube and the reflective sleeve define a sterilization space, the lower portion of the sterilization space is a base, and a UVC light-emitting component is arranged on the base and used for sterilizing water flowing through the sterilization space; the sterilized water flows out of the sterilization space, passes through the upper part of the heat dissipation shell, directly dissipates heat to the outside through the heat dissipation shell and flows out of the water outlet. The laminar flow type UVC module disclosed by the invention has better heat dissipation performance, and the sterilization efficiency and the sterilization intensity can beimproved.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, in particular to a laminar flow UVC module. Background technique [0002] With the improvement of living standards, people's requirements for sanitary conditions are getting higher and higher, and consumers' demand for household sterilization is increasing. Among them, the miniaturization of UVC LED chips and modules makes sterilization components more extensive. Its small size allows it to be embedded in a variety of household appliances, such as refrigerators, air conditioners, and washing machines. It can also be attached to various living utensils, allowing users to carry them with them, such as water cups, Items such as lunch boxes and toothbrushes can be attached to it. The sterilizing principle of this UVC LED is to destroy or terminate the process of DNA replication of bacteria, spores and viruses through ultraviolet irradiation, so as to achieve the purpose of effectiv...

Problems solved by technology

[0004] UVC modules in the prior art such as figure 1 as shown, figure 1 It is a schematic diagram of an existing UVC module, wherein the ultraviolet light source 101 is located at the bottom, and the quartz glass 102 is used to accommodate the water flow (indicated by the direction of the arrow) above it. The outside of the quartz glass 102 is surrounded by a metal shell 103, and the whole module The upper part of the module is covered with a plastic shell 104. It should also be noted that the water inlet 105 is located directly above the light source. It can be seen that the light source and heat dissipation module are installed at the bottom of the module for irradiation and sterilization, and the water flow enters from the upper end of the module. It is laminar flow, and the sterilization chamber is a long cylinder, which improves the surface uniformity and penetration of light, and the volume of the rectification area is relatively large. However, the above-mentioned existing UVC modules have the following disadvantages: UVC modules simply use the components themselves to dissipate heat , and quartz glass cannot dissipate heat, so it cannot dissipate heat from the surrounding metal shell, so the heat dissipation function is poor, and higher power UVC light sources cannot be used, resulting in low sterilization efficiency and weak sterilization intensity
