Self-cleaning sterilizer for external water tank

Abstract

The invention discloses a self-cleaning sterilizer for an external water tank and relates to the technical field of water quality purification. The self-cleaning sterilizer comprises a sterilizing lamp, a rectifier, a contactor, a water pump, a sterilization tank and a switch, wherein a water inlet of the water pump can be connected with a water outlet of the external water tank, a water outlet of the water pump is connected with a water inlet of the sterilization tank, and a water outlet of the sterilization tank can be connected with a water inlet of the external water tank; during working, water in the water tank enters the sterilization tank through the water pump, the sterilizing lamp emits ultraviolet rays to kill bacteria and microorganisms in water, meanwhile, the ultraviolet rays irradiate oxygen in water, ozone is formed and can kill the bacteria and the microorganisms in the water, ozone can be decomposed in certain period of time, no residues are left in the water, the bacteria and the microorganisms in the water are killed by the ultraviolet rays and the ozone simultaneously in a sterilizing process, so that the sterilizing rate is increased, the sterilizing effect is obvious, and normal water usage of users cannot be influenced in the sterilizing process; the operation is simple, sterilizing apparatus of the whole device is just the sterilizing lamp, and the sterilizing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to an external water tank self-cleaning disinfector. Background technique [0002] People are closely related to water in their lives, and the quality of water is closely related to people's health. With the intensification of industrialization and urbanization, water pollution has become more and more serious, and people's drinking water is full of a large number of bacteria. and microorganisms, endangering people's health; as my country's economy is in a period of rapid development, a large number of high-rise buildings such as apartments and office buildings have emerged, and people's water consumption is increasing. The water tank, because the water in the water tank and the pool sometimes stays for a long time, it is polluted by various microorganisms and bacteria, so that the water quality index of the water cannot meet the hygienic standard, resulting in secondary po...
