Embodiment approach

[0016] Such as figure 1 , figure 2 , image 3 As shown, the transparent mouth mask of the present invention includes that the filter element is movable and replaceable, and is added to the air inlet of the blower fan. The air duct 6 is connected, the blast duct 6 is connected with the blast outlet 8, and is connected with the negative pressure fan 4 and the negative pressure air duct 7 at the bottom of the transparent helmet 2, and the negative pressure air duct 7 is connected with the negative pressure inlet 9. The middle upper part of 2 links to each other with cap liner 3, and adds cooling fan to regulate body temperature in appropriate position, and the bottom of transparent helmet 2 is connected with neck circumference 10 quickly, easy to replace, and neck circumference 10 has stopped virus channel.

Abstract

The invention provides a transparent mask integrating a mask, goggles, a helmet and a neck circumference. The transparent mask filters the mask at the edge of the mouth,; the mask moves to the other part from the face,; the filtered air is sent back to the face by a pipeline and a fan; the air pipe is used for conveying filtered air to the nose; the fixing function of a bracket for separating clean air from dirty air is realized; the periphery of the nostrils is in a positive air pressure state, unfiltered air is prevented from entering the nostrils, the comfort is improved and the consumptionis reduced through electric power assisted breathing, the whole head is protected by a safety helmet with a deepened transparent steel plate called as pc, and a cooling fan is additionally arranged at the proper position to adjust the body temperature.

Description

technical field [0001] The invention relates to labor protection, in particular to a novel transparent mask. Background technique [0002] The N95 mask is one of the 9 types of particulate protective masks certified by NIOSH. "N" means not resistant to oil. "95" means that when exposed to a specified number of special test particles, the particle concentration inside the mask is more than 95% lower than the particle concentration outside the mask. Among them, the value of 95% is not the average value, but the minimum value. N95 is not a specific product name, as long as it meets the N95 standard and passes the NIOSH review, it can be called "N95 mask". The protection level is N95, which means that under the testing conditions specified in the NIOSH standard, the filtration efficiency of the mask filter material for non-oily particles (such as dust, acid mist, paint mist, microorganisms, etc.) reaches 95%. Another five percent is a pain point 1. Other anti-particulate mas...
