Problems solved by technology

[0013] (4) Not conducive to children's growth
In addition, due to the weak light and the resulting low air pressure in foggy days, some people will experience laziness and depression in foggy days
[0016] (6) Affect reproductive ability
[0022] The anti-smog masks of the prior art all purify the air through filtration or adsorption, but nitrogen oxides or sulfur oxides in the air cannot be removed by filtration or adsorption.

Embodiment 1

[0037] The catalyst is prepared by an impregnation method, the carrier is a mixture of cerium oxide nanocubes and gibbsite, and its mixing mass ratio is 2:1;

[0038] The active component is a composite oxide of copper, zirconium, vanadium and tungsten, and its molar ratio is 1:1:1:1, and the weight content of the active component in the catalyst is 2%;

[0039] The co-catalyst is silver and anatase titanium dioxide, the molar ratio of Ag to Ti is 2:5, and the weight content of the co-catalyst in the catalyst is 1%.

[0040]Open the zipper to open the structure, put in the catalyst to form a catalyst structure layer. And then prepare mouth mask of the present invention according to following structure. It includes a mask body covering at least the wearer's mouth and nose, which has an inner contact layer in contact with the wearer's skin and a surface layer arranged on the side away from the inner contact layer. A filtering structure is provided between the inner contact laye...

Abstract

The invention discloses a mask for preventing and treating haze. The mask is provided with a catalyst structure layer. After haze air passes through the mask provided by the invention, PM2.5 particles, nitric oxide and sulfur oxide are all reduced to an extremely low level, so that respiratory health is effectively protected.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a mask for preventing haze. Background technique [0002] Haze weather is a state of air pollution. Haze is a general expression of the excessive content of various suspended particulate matter in the atmosphere, especially PM2.5 (particulate matter with an aerodynamic equivalent diameter less than or equal to 2.5 microns) is considered to cause haze. The "culprit" of the weather. [0003] Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the surface. It mostly occurs in autumn and winter, and is the product of condensation (or sublimation) of water vapor in the air near the surface. The existence of fog will reduce the transparency of the air and deteriorate the visibility. If the horizontal visibility of the target is reduced to within 1000 meters, the weather phenomenon of water vapor condensation (or sublimati...
