Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the technical field of flow type sterilization device, concretely is a large flow flow type sterilization device. BACKGROUND

[0002] Deep ultraviolet, also known as UVC, can penetrate the cell membrane and nucleus of microorganisms and is widely used as a sterilization method. UVC LED is a high-efficiency and environmentally friendly sterilization technology. There are some UVC LED flow type sterilization products on the market. Flow type sterilization refers to a sterilization device that does not contact the water source. In the instant of water flow, sterilization treatment is carried out by using ultraviolet light irradiation. The advantage of this sterilization method is that there is no secondary pollution. In order to improve the sterilization effect of LED on water flow, the existing solutions mostly use methods such as extending the length of the water pipe to extend the water flow path, increasing the power of LED, or extending the sterilization time to meet the sterilization requirements. However, extending the length of the water pipe will increase the size of the device, which is not conducive to the compactness and miniaturization of the device. Increasing the power of LED and extending the sterilization time will increase the energy consumption of the device, which is not conducive to energy saving.

[0003] In the patent with the authorization announcement number CN 213171571 U, a large flow flow type ultraviolet sterilization device is disclosed. The inner surface of the sterilization cavity is covered with an ultraviolet reflective layer that has high reflection effect on ultraviolet light, which can improve the reflectivity of UVC light and reduce energy loss, greatly improving light utilization and sterilization efficiency. The optical assembly is provided with a lamp bead module, a multi-prism lamp plate, a reflector and an optical lens, which can improve the light utilization and sterilization efficiency. However, the device needs to be provided with a flow dividing member, a rectifying water cooling assembly, etc. by surrounding the second flow area with the first flow area, which makes the device structure more complex and the water body in the device more likely to remain. Since the optical assembly is located at the center of the device, and the heat dissipation assembly can only be located at the surface side of the device, the heat dissipation efficiency is low, and stronger heat dissipation equipment is needed.
