Haze-proof cap

Abstract

The invention discloses a haze-proof cap, which comprises an upper case, a support frame, a memory cotton liner, a lower case, a transparent wind blocking cover, a filtering material assembly, a fan assembly, an LED (light emitting diode) lamp group, a rechargeable battery, a circuit board and a switch assembly, wherein the memory cotton liner is internally lined at the inner side of the support frame; the LED lamp group and the rechargeable battery are assembled on the support frame; the circuit board and the switch assembly are assembled on the lower casing; the support frame, the upper case and the lower case are jointly assembled to form a C-shaped cap body; the transparent wind blocking cover is assembled at the sealed end of the cap body; the filtering material assembly and the fan assembly are assembled and arranged at the opening end of the cap body and filtered and purified air is input into a space formed at the inner side of the transparent air blocking cover through an air guide pipe. The haze-proof cap has the advantages that the wearing is simple and convenient; the three-dimensional air purification effect is achieved in a narrow and small space in the mouth and nose position; the use performance is safe and reliable; the invasion caused by outgoing in haze weather is effectively avoided.

Description

Technical field [0001] The invention relates to the technical field of anti-smog products, in particular to an anti-smog cap. Background technique [0002] In recent years, the rapid development of the domestic industrial economy has caused a serious deterioration in air quality, and the number of days of haze weather has increased day by day. PM2.5 particulate matter is the main component of the haze, and it is the most harmful to the human body. These fine particles with a diameter of less than or equal to 2.5 microns are densely suspended in the air and are almost invisible to the naked eye. When people breathe, they follow the air. Enter the respiratory tract and lungs, cause diseases such as tracheitis, pneumonia, and endanger human health. People are aware of the dangers of haze and more and more people choose to wear anti-smog masks when traveling. However, the anti-smog mask has a very unsatisfactory filtering and protection effect on PM2.5. Wearing an anti-smog mask ne...

AI Technical Summary

Problems solved by technology

However, the anti-smog mask has a very unsatisfactory filtering and protective effect on PM2.5. Wearing an anti-smog mask needs to fit the face, completely cover the nose and mouth and keep it sealed. Limited by the way of wearing, it also has certain limitations in application. Limitations, moreover, are usually disposable and cannot be disassembled, washed, replaced and reused
