Dustproof sterilizing screen window

Abstract

The invention relates to a dust-proof disinfection window screen, wherein the outer side of fixing frame has 40-60deals of metal meshes; the inner side of fixing frame has the inner window screen with 30-50deals; the surfaces of inner and outer window screens carry the nanometer Ti02 light catalyst doping with metal ion or non-metal ion; the metal ion comprises Co2+, Cr3+, Cu2+, Fe3+, Mo5+, V5+ or W6+; and the non-metal ion comprises N3-, C4-, or P6-; the surfaces of inner and outer window screens also can carry the nanometer TiO2 light catalyst decorated with expensive metal Pt, Ag, Au, Ru, Pd, or Rh; and said surfaces can carry the composite light catalyst with WO3-TiO2, SnO2-TiO2, Cds-TiO2, or V205-TiO2. And the fixing frame and the window frame are arranged with power controller; the outer window screen via the wire is connected to the 1000-3500V direct-current high-voltage anode of power controller; the inner window screen via wire is connected to the 20-35V direct-current low-voltage cathode of power controller.

Description

technical field [0001] The invention belongs to the technical field of special-purpose doors, windows or similar closures, and particularly relates to a screen window with dust-proof and sterilization function. Background technique [0002] The harm of indoor air pollution to health has attracted the attention of the whole society. Therefore, a large number of patents and products for indoor air sterilization and purification have been produced, especially the application of nano-photocatalytic air sterilization and purification technology, which can provide the solution to indoor air pollution problems. effective method. However, at present, independent air purification devices are widely used to sterilize and purify indoor air. The problems are high energy consumption, high noise, and often there are dead spots for purification. It is difficult to completely solve the problem of indoor pollution. [0003] Opening windows to allow air to circulate naturally is considered t...

AI Technical Summary

Problems solved by technology

Therefore, while the outdoor air dilutes the indoor dirty air, new pollution is produced.

Chinese patent ZL03226651 provides a method to solve the above problems, but it actually installs the air purification device on the window. Although the effect of dust removal is better, it has high energy consumption, high noise and poor light transmission for a long time. In particular, the comfort of "coming slowly" produced by the natural flow of air is changed, so the practicality is poor

The applicant's patent number is ZL03219014.X, and the Chinese patent titled "Nano Photocatalytic Antivirus and Sterilization Screen Window" uses nano-TiO 2 Loaded on the window screen for air sterilization and purification, although it has a certain effect, it can only kill the virus and bacteria that naturally adhere to the nano-photocatalytic window screen, and can only use less than 5% of the ultraviolet light in sunlight to stimulate its photocatalysis Sterilization and purification, the sterilization efficiency is very low, especially most of the floating dust and pollen still enter the room through it, and the dustproof ability is poor

The patent application number 200510200652.0 and the Chinese patent titled "Sterilized Dustproof Window and Its Manufacturing Method" also use nano-TiO 2 It is applied on the mesh surface for air sterilization and disinfection, and at the same time it is proposed to energize the mesh surface to enhance the ability of the mesh surface to absorb dust. This patent has several deficiencies: First, the pure nano-TiO loaded on the window screen 2 The photocatalyst can only use less than 5% of the ultraviolet light in the sunlight to stimulate its photocatalytic sterilization and disinfection function, so its photocatalytic sterilization and disinfection efficiency is very low; second, the purpose of electrifying the mesh surface is to make the free electrons of the mesh move in a directional manner, The ability of the mesh surface to absorb dust is enhanced. Although it may produce a certain adsorption effect, the mesh surface can only absorb charged dust particles in the air, and most of the particle pollutants in the air are uncharged neutral particles, that is, A large number of neutral particle pollutants will still enter the room through it, so its dust isolation effect is poor
