Abstract
The utility model belongs to a highly purified and dustproof labor protection health care article. The utility model is composed of a purified filter cover, a plastic cover frame, a sponge soft pad and an elastic and telescopic bandage, wherein, the purified filter cover is composed of a middle filter layer and a vice-highly effective filter layer, both sides of the middle filter layer and a vice-highly effective filter layer are nonwoven cloth, and the middle parts of the middle filter layer and a vice-highly effective filter layer aare provided with thick filter layers. The utility model can be a disposable appliance. The clean degree of the utility model can reach thousand degree to ten thousand degree, and namely, microparticles which equal or are more than 0.5 mum are 35 to 350 per liter, and microparticles which equal or are more than 0.5 mum are 0.23 to 2.3 per liter.
Description
The utility model belongs to the high mouth mask that purifies of a kind of dedusting, is mainly used in various dirt ore deposit miners such as underground work, colliery, cement plant, velvet apple textile mills etc. and sends out dirt operation workman.Can prevent occupational diseases such as pneumoconiosis well.Be applicable to that higher clean area operating personnel use, in case the bacterium particulate in oral cavity enters clean area.Existing common mouth mask mostly is gauze or other spun cotton cloth is made, and its dust removing effects is very poor, can only intercept 50 to up to a hundred microns block.There is not the effect that purifies particulate.Because of the cotton products good heat insulating, permeability is poor, makes the people feel to feel suffocated, and especially more is reluctant to use in work.
The purpose of this utility model addresses the above problem exactly, provides that a kind of permeability is good, simple in structure, the anti-pneumoconiosis mouth mask of good purification.
The utility model is by movable udst separation cover removably, and plastic jacket frame, the soft packing of sponge and telescopic bandage are formed.Movable udst separation cover is thick, the inferior efficient filtering layer composition of neutralization by the nonwoven in two outsides therebetween.
The utility model is easy to use, and permeability is strong, is no more than 1250Pa, can be used as disposable utensil, also can repeatedly use, and must clean.But contain inferior efficient filtering layer person only as disposable use.Good purification, its cleanliness factor can reach 1,000 or 10,000 grades.
Figure one is the structural representation of utility model:
As shown in the figure, the utility model is made up of plastic jacket frame 1 purification filter bowl 2 soft sponge packings 3 and retractility bandage 4.It purifies filter bowl by nonwoven 2
12
2Coarse filtration layer 2
3Middle filtering layer 2
4With the efficient filtering layer 2 in Asia
5Form.
The utility model is made according to deep layer cleaning principles such as the diffusion effect that purifies, obstruction effect, gravitational effect, electrostatic effects, and adopt optimum seeking method to select the proportional formation of best group, so the purifying and dedusting effect is best, permeability is also fine, make it to keep optimum state, resistance to suction＜1250Pa.
In order to improve cleanliness factor, increased inferior efficient filtering layer, make it to reach 1,000 grades, but can only be as disposable use.Inferior efficient filtering layer lost efficacy after washing, and cleanliness factor is reduced to 10,000 grades, repeatedly uses anti-dust respirator but can be used as, and is still effective than common mouth mask.General common mouth mask is all below 100,000 grades even below 1,000,000 grades.
