Intelligent control device for ultraviolet sterilization

Abstract

The invention provides an ultraviolet sterilization intelligent control device which comprises a shell, a water inlet end and a water outlet end, a circuit board, an induction assembly used for detecting fluid flow and a sterilization assembly used for sterilizing fluid are installed in the shell, the water inlet end, the induction assembly and the water outlet end are sequentially communicated, and the sterilization assembly is installed between the induction assembly and the water outlet end; the sterilization assembly comprises a UVC sterilization lamp with adjustable output power, and the circuit board adjusts the output power of the UVC sterilization lamp according to the flow of the fluid detected by the induction assembly. The induction assembly and the sterilization assembly are sequentially installed in the flowing direction of the fluid, so that the induction assembly can detect the flow of the fluid at first, then the circuit board controls the output power of the sterilization assembly, the illumination intensity of the UVC sterilization lamp is adjusted in real time according to the flow of the fluid, and the sterilization effect is guaranteed under the condition of energy conservation; and the flow velocity of fluid in the shell can be monitored in real time, the functions are diversified, and the service life of the UVC germicidal lamp can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of ultraviolet sterilization, in particular to an intelligent control device for ultraviolet sterilization. Background technique [0002] Traditional ultraviolet sterilizers generally use mercury lamps to generate ultraviolet rays, which play a sterilizing role by continuously irradiating fluids. Mercury lamp type ultraviolet sterilizer has the following disadvantages: complex structure, large volume, can not be flexibly installed inside the machine; complex production process, high manufacturing cost; need the main control board to give a start signal to run, and it can be produced normally after a few minutes of operation Ultraviolet light consumes a lot of power during operation, and its life is affected by the number of switches. In addition, if the mercury lamp type ultraviolet sterilizer is damaged, the leaked mercury will pollute the environment, and after the "Minamata Convention", mercury lamps hav...

Problems solved by technology

The mercury lamp type ultraviolet sterilizer has the following disadvantages: complex structure, large volume, and cannot be flexibly installed inside the machine; Ultraviolet light, which consumes a lot of power during operation, and its life is affected by the number of switches

However, at present, the service life of LED lamp beads is about 3000 hours, and they are generally lit for a long time, resulting in a service life of only 3-4 months, and the fluid flow rate in the pipeline of each machine is different, and the existing technology cannot effectively monitor The flow rate, and the power of the LED lamp beads cannot be adjusted according to the flow rate
