Water cleaning device

Abstract

Disclosed is a water cleaning device. A containing space is arranged inside the water cleaning device. A plurality of transparent photocatalyst units with at least one opening are arranged in the containing space at equal intervals. Water to be cleaned can be guided and injected into the water cleaning device to flow along a zigzag water flow path inside the water cleaning device, accordingly, the flowing time of the water to be cleaned inside the water cleaning device is prolonged, and the sterilization clean time of the water to be cleaned inside the water cleaning device is prolonged. Different from existing photocatalyst glass plates, the photocatalyst glass plate is composed of a glass substrate, a photocatalyst coating film and a protective film, the protective film is made of a water corrosion resisting material, and the phenomenon that external water molecules invade through holes in the photocatalyst coating film to corrode the glass substrate can be avoided; the photocatalyst glass plate will not have the glass substrate acid regurgitation phenomenon; the photocatalyst coating film coating the glass substrate will not be disengaged from the glass substrate even when the glass substrate is in use for a long time.

Description

technical field [0001] The invention relates to the related technical field of cleaning and sterilization, in particular to a water cleaning device which uses ultraviolet light sterilization technology and photocatalyst cleaning technology at the same time. Background technique [0002] Whether it is commercial fish farming or ornamental aquarium farming, maintaining the water quality and temperature of the breeding environment and at the same time properly isolating external disease sources is the only way to make farmed fish and shrimp grow healthily. [0003] As we all know, farmed fish are most afraid of encountering diseases and insect pests. Once diseases and insect pests occur, the whole pond of farmed fish may become sick or die; therefore, in order to avoid similar situations, farmers usually put antibiotics, formaldehyde or other drugs into the fish. In the breeding pond, thereby preventing the farmed fish from being attacked by diseases and insect pests. However,...

AI Technical Summary

Problems solved by technology

Among them, since the glass substrate is mainly composed of calcium oxide, sodium oxide, magnesium oxide, and silicon dioxide, the chemical reaction between sodium ions and water molecules will cause the glass substrate to produce acid vomiting. Lateral erosion will cause the photocatalyst film coated on the glass substrate to gradually fall off
