Abstract

The invention discloses a UVC LED water sterilization device capable of automatically adjusting optical power, and relates to deep ultraviolet disinfection and electronic control. The device is provided with a data acquisition and processing module, a power supply module, a light source module and a display and control module. The data acquisition and processing module comprises an MCU, a distancesensor, an AD converter and a memory. The distance sensor is used for acquiring analog signals of information of the distance between a light source and the water surface, the analog signals are converted into digital signals through the AD converter, and the digital signals are transmitted to the MCU for processing. The MCU is used for storing the data in the memory and is connected with the power supply module. The display and control module comprises a Bluetooth and an LCD touch display screen, and real-time data acquired or calculated by the MCU is transmitted through the Bluetooth to theLCD touch display screen for display. The output end of the LCD touch display screen is connected with the MCU, and the received touch input data is transmitted to the MCU to be processed. Automaticcontrol, precise sterilization, energy conservation, environmental protection, visual data, no damage to substances and no chemical residues are realized.

Description

technical field [0001] The invention relates to the technical field of deep ultraviolet disinfection and electronic control, in particular to a UVC LED water body sterilization device with automatic optical power adjustment. Background technique [0002] The means of inactivating the new coronary pneumonia virus (SARS-CoV-2) can be divided into chemical disinfecting methods (such as ether, 75% ethanol, chlorine-containing disinfectant (84 disinfectant), peracetic acid, chloroform and other fat solvents, etc. ), and physical disinfecting methods (such as UV irradiation or heating at 56°C for 30 minutes, etc.). Although chemical disinfection is the most widely used, most disinfectants have toxic and side effects on the human body. Compared with chemical disinfecting, physical killing is relatively less harmful to the human body, and there is no secondary pollution. Since the heating scheme can cause damage to the object itself, the scope of use is narrow. UV disinfection tec...
