Integrated positive pressure protective mask

Abstract

An integrated positive pressure protective mask is formed by connecting a transparent protective mask, an under-chin mask and an air filter in a sealed manner through an air pipe. A hollow elastic sealing rubber strip is arranged at the contact part of the transparent protective mask and the face, and the lower part of the transparent mask is connected with the elastic sealing rubber strip through the under-chin mask. A filter frame of the air filter is covered with a filter cloth bag, a centrifugal fan is arranged in the filter cloth bag to blow purified and filtered air into the protective mask through the air pipe with vent holes in the head, air flow is blown into the protective mask from top to bottom, positive pressure is kept, and the under-chin mask exhausts the air. The integrated positive pressure protective mask can be used in cooperation with protective clothing, so that virus invasion is effectively prevented. The mask can also be used for preventing sand wind, haze and wind and rain, and the defect of wearing the mask is overcome. The protective mask is suitable for various people to wear.

Description

[0001] Technical field [0002] The invention relates to an integrated positive pressure protective face mask equipped with an air filter to transport purified air. Background technique [0003] At present, the existing protective masks have the following deficiencies: most of them are split protective masks, which are composed of masks, goggles, protective masks, etc., and each part cannot be seamlessly connected, and the skin connecting the gaps is directly in contact with polluted air; If the virus in the air invades, it must be kept sealed. Wearing a mask, goggles, and protective mask for a long time will oppress the human face, causing indentations, hindering blood circulation, soaking in sweat, and even damaging the skin; although the area of ​​the mask is large, the effective use area is limited. Masks that rely on breathing filters have difficulty breathing, the face is covered, people's faces cannot be seen clearly, the pronunciation is distorted, and language and exp...

Problems solved by technology

[0003] At present, the existing protective masks have the following deficiencies: most of them are split protective masks, which are composed of masks, goggles, protective masks, etc., and each part cannot be seamlessly connected, and the skin connecting the gaps is directly in contact with polluted air; If the virus in the air invades, it must be kept sealed. Wearing a mask, goggles, and protective mask for a long time will oppress the human face, causing indentations, hindering blood circulation, soaking in sweat, and even damaging the skin; although the area of ​​the mask is large, the effective use area is limited. Masks that rely on breathing filters have difficulty breathing, the face is covered, people's faces cannot be seen clearly, the pronunciation is distorted, and language and expression communication is blocked; the water vapor generated by human breathing condenses in the mask, increasing breathing resistance, and the inside of the mask is wet and close Skin; the water vapor produced by human sweating condenses in the goggles, forming fog and affecting vision; the split protective mask is troublesome to wear and increases the chance of virus infection

The existing protective masks and goggles are generally designed for medical use, which are not suitable for daily wear, nor can they replace the protective effect of masks
