Water dispenser photocatalytic gas phase sterilizer

Abstract

The invention relates to a photocatalytic gas-phase sterilizer of a water dispenser. The photocatalytic gas-phase sterilizer comprises more than one centrally perforated photocatalytic ceramic sheet which is stacked into a cylinder through a screw rod, the screw rod is arranged on the outer end surface of the photocatalytic ceramic sheet and is locked by a nut, the photocatalytic ceramic sheet is separated by a wafer to form a gas-phase photocatalytic reaction tank, an ultraviolet lamp is formed in the central hollow part of the cylinder, the lower end of the ultraviolet lamp is fixedly arranged on a lamp holder, a filtering sponge is sleeved around the outer circumference of the cylinder and is at a compression stage, an air outlet is formed in the center of an upper cover plate and is communicated with the photocatalytic reaction tank through circumferential intervals around the ultraviolet lamp, a lower cover plate is fixedly arranged on a base, and a ballast and a pressure sensing switch circuit are arranged in the base. The photocatalytic gas-phase sterilizer disclosed by the invention has an assembly structure and the advantages of simplicity, convenience, practicability, reliable performance and easiness in popularization, overcomes the defects of the barreled-water dispenser in air sterilization and disinfection aspect in the prior art, and combines with the existing photocatalytic technology, so that the drinking water is more health and safer, is easy to recycle after being used, is not polluted and can be recycled.

Description

technical field [0001] The invention belongs to the technical field of air filtration and sterilizing devices for drinking water dispensers, and in particular relates to a sterilizer which adopts photocatalytic oxidation reaction to degrade organic pollutants in the air and eliminate bacteria from entering the drinking water dispenser. Background technique [0002] With the development of the country's economy, people's requirements for the quality of life are gradually improving, and drinking water safety is getting more and more attention. Therefore, drinking water dispensers from the pipe network of waterworks are widely used. Daily water dispensers mostly use bottled water sources. They have passed strict quality inspections when they leave the factory, and they can be guaranteed for about three months without opening, thus ensuring the safety of regular drinking requirements. But once opened, since the water dispenser will continue to inhale air to replenish during the ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the existing water dispenser in the waterproofing process, the air will enter the water dispenser to pollute the water source, resulting in excessive microbial content in the water, which is not suitable for drinking, and a photocatalytic gas phase sterilizer for drinking fountains is provided.
