Abstract
The utility model belongs to the respiratory protection technology, particularly relates to a protection respirator, which aims at the problems that existing protection respirators are not smooth to breath, can not discharge hazardous substances, and are easy to breed bacteria and leak and the like. The protection respirator comprises an outer layer, an inner layer, a cover body, an adjusting belt and a moving adjusting bucket, wherein the cover body comprises an insulation layer which is arranged between the outer layer and the inner layer. The protection respirator further comprises a nasal splint, exhalation valves and a composite filter layer, wherein the composite filter layer is arranged between the insulation layer and the inner layer, the nasal splint is arranged in the middle position of the inner side of the cover body, the two exhalation valves are arranged on the composite filter layer corresponding to two nostrils, lateral rhinotomy tighten belts are further symmetrically arranged on the upper part of the inner layer of the cover body, a jaw tighten belt is arranged on the lower end of the cover body, and a plurality of silicone rubber wires are arranged on the inner contour of the cover body. The protection respirator enables the air inside and outside the cover body to exchange, can discharge heat and hazardous substances, and enables clean air to enter, thereby effectively reducing leakage problems and the like.
Description
Technical field
The utility model belongs to respiratory protection technology, is specifically related to a kind of protective mask.
Background technology
At present, at home on market, PM2.5 protective mask is divided into and has the protective mask of outlet valve and insert filter disc type, composite filter chip two classes without the protective mask of outlet valve from structure.Wherein have protective mask and the composite filter chip of outlet valve to be generally used for Occupational health protection, be generally disposable (disposable), the smooth and easy profile of exhaling is single; Insert filter disc type structure and be generally used for daily life protection, reusable (filter disc is replaceable), good looking appearance.China at industrialization high speed development, PM2.5 cannot overcome in a short time, PM2.5 protective mask for daily life will have larger market, but common PM2.5 mouth mask in use still exists to exhale and has some setbacks in the market, in cover, thermal accumlation causes discomfort, long periods of wear harmful substance can not be discharged, the problem of bacteria breed and leakage, and plug-in type filter disc structure is not covered with cover body, according to aerodynamic principle, air-flow can enter respiratory tract from the less place of filter disc ambient air resistance, and filter disc can not effectively play a role.Therefore need to aly can guaranteed performance have again both artistic and practical PM2.5 protective mask concurrently.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can makes to cover inner air and outer air and exchange, and heat and harmful substance can be discharged, and pure air enters; Effectively lowered a kind of protective mask of the problems such as leakage.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: a kind of protective mask, comprise by outer (10), internal layer (4), be arranged on the cover body that the heat-insulation layer (6) between skin and internal layer forms, accommodation zone (2) and be arranged on the activity adjustment button (1) on accommodation zone (2), be characterized in: it also comprises nose clip (9), outlet valve (7), combination filtering layer (3), described combination filtering layer (3) is arranged between heat-insulation layer (6) and internal layer (4), described nose clip (9) is arranged on centre position inside cover body, on described combination filtering layer, corresponding two places, nostril are provided with two outlet valves (7), on described cover body internal layer, part also arranges symmetrical nasal side belt tensioner (8), lower end arranges chin belt tensioner (5), at described cover body internal layer profile, some sections of silicon rubber lines (11) are set.
Further preferred embodiment: described skin (10) is selected antibiotic facing material; Described heat-insulation layer (6) is selected light-duty ventilative insulation material; Described internal layer (4) is selected natural fabric material; Described combination filtering layer (3) selects three layers of polypropylene electret filter materials compound.
Compared with prior art, the utility model protective mask adopts built-in outlet valve, clean air can be discharged and sucked to the gas of exhalation, and the silicon rubber line of cover body inner side and the belt tensioner at nose and chin position can effectively lower slip, the filter disc design that is covered with cover body has fundamentally improved filter efficiency.The present invention selects antibiotic facing material, in conjunction with built-in outlet valve and high-performance static filter material, the position of the coated nose of cover body and chin is tightened up to process to reduce and is leaked, the personnel that guaranteed can effectively filter the air of suction, complete machine is not less than 95% to the filter efficiency of PM2.5, the foul smell of breathing out is discharged by outlet valve, good protection is provided to personnel's respiratory system of wearing this mouth mask, improve simultaneously and breathe comfortableness and whole perception effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 cutaway view;
Fig. 3 is the partial sectional view of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of protective mask in the present embodiment, comprise the skin 10 of being made by first-chop antibiotic facing material, the internal layer 4 made from natural fabric material, be arranged on the cover body that heat-insulation layer 6 that the light-duty ventilative insulation material of use between skin and internal layer makes forms, accommodation zone 2 and be arranged on the activity adjustment button 1 on accommodation zone 2, be characterized in: it also comprises nose clip 9, two outlet valves 7, with three layers of compounded combination filtering layer 3 of polypropylene electret filter material, described combination filtering layer 3 is arranged between heat-insulation layer 6 and internal layer 4, described nose clip 9 is arranged on centre position inside cover body, on described combination filtering layer, above corresponding two nostrils, be provided with two outlet valves 7, on described cover body internal layer, part also arranges symmetrical nasal side belt tensioner 8, lower end arranges chin belt tensioner 5, at described cover body internal layer profile, some sections of silicon rubber lines 11 are set.
The operation principle of protective mask of the present utility model:
When air-breathing, in cover body, in negative pressure state, outlet valve cuts out, and air-flow enters human respiratory by each layer.Outer and heat-insulation layer is as the dust of pre-filtering filtering larger particles, the most PM2.5 of PM2.5 filtering layer filtering and above particle, and finally the internal layer by the skin of fitting enters human respiratory.
When exhaling, cover body is in barotropic state, and outlet valve is opened, and air-flow, through internal layer, directly passes through outlet valve, outer discharged to ambient atmosphere without filter disc.
After respiration action, the air of suction is clean air like this, discharge be foul smell (nitrogen, oxygen, carbon dioxide, steam, metabolite and heat).
