Description

An electronic anti-fog mask

technical field

The utility model relates to the field of masks, in particular to an electronic anti-smog mask.

Background technique

A mask is a device that can prevent pollutants in the air (such as smog, dust particles) from entering the human body through the mouth and nose. Wearing a mask can reduce the occurrence of respiratory diseases to a certain extent; and for working in dust and other pollution For workers in an environment with a lot of pollutants, wearing a mask can also reduce the intrusion of pollutants to a certain extent.

Ordinary masks in the prior art are utensils that cover the mouth and nose. Although they have a filtering effect, wearing them for a long time will hinder the normal circulation of the air, which will easily cause the human body to feel that breathing is not smooth, and will increase the work of the lungs simultaneously. The pressure will form a feeling of suffocation and stuffiness due to the poor gas circulation of the human body and the inability to replace fresh air. There are also some electronic masks with built-in fans on the existing market, but the structural design of this type of masks is not very reasonable. At the same time, the built-in fans are all set in the body of the cover, so it is very troublesome to take out the fan when replacing the mask; or the fan and the mask It is a one-piece disposable mask, which is expensive to use for a long time.

Chinese patent (notification number is CN205233534U) discloses a kind of dust-proof anti-odor anti-fog haze electronic mask with built-in detachable fan. The electronic mask of this patent comprises a cover body, the two sides of the cover body are provided with hanging straps, the inner layer of the cover body is provided with a detachable small air filter device, and a fan is arranged in the small air filter device. The electronic mask provided by this patent makes it very easy for the mask wearer to inhale and exhale, and no longer has the feeling of suffocation when wearing a mask, and at the same time realizes air filtration through the mask filter. However, the patented electronic mask uses a filter to filter the air. The filter can play a certain role for ordinary light smoke, but the effect is not obvious for major haze weather.

Therefore, it is necessary to provide an electronic anti-fog mask with good filtering effect and easy to use.
