Portable anti-haze device

Abstract

The invention discloses a portable anti-haze device. The portable anti-haze device comprises a filter device and a breather connected with the filter device through a hose. The filter device is fixed to a light foam helmet, and comprises two filter screen supporting layers, a filter layer and a light foam inner shell. The filter layer is arranged between the two filter screen supporting layers, and the filter screen supporting layers and the filter layer are fixed to the light foam inner shell. According to the portable anti-haze device, the influence of expiration on glasses can be avoided, the hair is protected against contamination, and the filtering effect of the filter layer is improved.

Description

technical field [0001] The invention relates to a personal anti-haze product, in particular to a nasal congestion type anti-fog device with a one-way breathing valve. Background technique [0002] Recently, serious smog particle pollution has occurred in our country, especially in autumn and winter, smog pollution seriously affects people's quality of life. Although the existing masks on the market can play a good anti-smog effect, there are still some defects in the process of use, which need further improvement, as follows: [0003] 1. Part of the fit between the mask and the face is not tight, especially in the area near the nose. The moist air exhaled by the human body will be discharged upward along the gap between the mask and the face. If the user wears glasses, the exhaled water vapor will be very fast. Condensation on the glasses will cause blurred vision. Even if the gap is reduced by adding plastic aluminum strips, the effect is still unsatisfactory, and moisture...

AI Technical Summary

Problems solved by technology

[0003] 1. Part of the fit between the mask and the face is not tight, especially in the area near the nose. The moist air exhaled by the human body will be discharged upward along the gap between the mask and the face. If the user wears glasses, the exhaled water vapor will be very fast. Condensation on the glasses will cause blurred vision. Even if the gap is reduced by adding plastic aluminum strips, the effect is still unsatisfactory, and moisture will remain in the filter layer, which can easily cause bacteria to grow;

[0004] 2 Ordinary masks, the actual effective use position is only a small filter layer near the mouth, the filter layer on the cheeks is not actually used, and when the mouth filter layer is polluted, the mask needs to be replaced, which leads to The use efficiency of the filter layer is very low, and the service life of the mask is greatly shortened

[0005] 3 Another neglected problem is that in addition to the respiratory system, the hair also absorbs a large amount of smog particles

Since the hair itself has a large specific surface area and many small gaps, when the human body's hair is exposed to a large area of ​​smog, the smog particles are easy to adhere, which is not conducive to hygiene and may cause potential harm to the human body.
