Abstract
The utility model discloses a kind of air particle protective mask with one-way breather valve.The utility model main body comprises internal layer and skin, and arrange the intermediate filter layer of polypropylene melt-blown fibrous electret filter material between described internal layer and skin, main body arranges one-way breather valve, main body both sides mounting ear band.The utility model is on the basis adopting the high electret filter material of filter efficiency as air particle protective mask filter course, mask main body installs an one-way breather valve, greatly reduce respiratory resistance, and solve wear mouth mask after the problem that hazes of glasses.
Description
Technical field
The utility model relates to personal hygiene epidemic prevention, Atmospheric particulates protective articles field, specifically, is a kind of air particle protective mask with one-way breather valve with sandwich construction.
Background technology
The outburst of haze in recent years brings great impact to the healthy of people, the number showed increased of respiratory passage infectious disease patients in hospital during haze outburst, how effectively to avoid people to suck harmful substance, especially the personal protection of PM2.5 becomes the problem of people's general concern.The air particle protective mask that filter efficiency is high is one of important item needed for haze.At present, traditional cotton cloth respirator and single-layer nonwoven mask filtration efficiency low, only can protect particle larger in air, limited to the filtration of PM 2.5.Adopt the protective mask that high-efficiency fiber filter material or electret filter material make, good filter protection effect can be played to molecule, bacterium, virus, but there is the problem that respiratory resistance is large, people with glasses's glasses after wearing such mouth mask easily haze, and affect daily travel activity.
Utility model content
The purpose of this utility model is, overcomes the defect existed in above-mentioned prior art, provides the air particle protective mask that a kind of polypropylene fibre electret filter being provided with one-way breather valve makes.
The utility model is with the air particle protective mask of one-way breather valve, main body comprises internal layer and skin, arrange the intermediate filter layer of polypropylene melt-blown fibrous electret filter material between described internal layer and skin, main body arranges one-way breather valve, main body both sides mounting ear band.
Described main body is freshwater mussel type or cup type.Body top middle position arranges bridge of the nose folder, arranges sponge strip inside the mouth mask that bridge of the nose folder is corresponding.Described bridge of the nose folder adopts the sheet metal that can bend arbitrarily of outer layer covers soft plastics to make.Described skin is spun-bonded non-woven fabrics layer or the acupuncture nonwoven layer of cloth of water proofing property, and described internal layer is spunlace non-woven cloth layer.Described ear band arranges adjusting button.
The utility model is on the basis adopting the high electret filter material of filter efficiency as air particle protective mask filter course, mask main body installs an one-way breather valve, greatly reduce respiratory resistance, and solve wear mouth mask after the problem that hazes of glasses.
Advantage of the present utility model is: this air particle protective mask selects polypropylene melt-blown fibrous electret filter material as filter course, there is excellent barrier propterty, 99% is reached to the aerocolloidal filter efficiency of physical particles, by installing one-way breather valve, its inspiratory resistance is less than 120Pa, expiratory resistance is less than 40Pa, well below the 250Pa that standard specifies.Its integrated protection performance exceedes the requirement of China standard GB/T 2626-2006 KN95 grade.Bridge of the nose folder and the setting of sponge strip more contribute to mouth mask wear after with the laminating of face, play good protective action.In addition, mouth mask adopts folding design, is convenient to packaging and carries.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model, by profile, can be divided into freshwater mussel type and cup type.
Embodiment 1
As shown in Fig. 1, the utility model is a kind of freshwater mussel type air particle protective mask with one-way breather valve, comprise main body and ear band 6, main body comprises outer field spunbond or needle punched non-woven fabrics 1, polypropylene melt-blown fibrous electret filter material intermediate filter layer 2 and spunlace non-woven cloth internal layer 3, along the weldering line ball 4 on mouth mask main ring edge, the weldering of skin 1, intermediate filter layer 2 and internal layer 3 is pressed into one by being located at.The position of main body upper limb central authorities is provided with bridge of the nose folder 5, and presss from both sides corresponding position at internal layer and the bridge of the nose sealing strip is set, contribute to mouth mask and better fit in wearer, play good protective action.Main body side is outlet valve 7, as shown in Figure 3, outlet valve by the bottom of valve 71, adhesive sheet 72 and valve gap 73 form; Upon inhalation, adhesive sheet in Fig. 3 72 with 71 to fit tightly at the bottom of valve, form closure state (see figure 4), prevent haze from entering body interior; Adhesive sheet 72 is away from the bottom of valve 71 upon exhalation, and form opening (see figure 5), the gas of exhalation is discharged from outlet valve.
By the opening and closing of outlet valve, effectively reduce respiratory resistance.With adjusting button 8 and 9 on ear band 6, the length of ear band can be shortened, facilitate the people of different shape of face to use.
The electret air particle protective mask that the utility model makes of polypropylene melt-blown fibrous electret filter material, its filter efficiency is greater than 99%, and gas-flow resistance is less than 120Pa, meets the technical requirement of KN95 protection level in standard GB/T 2626-2006.
Embodiment 2
As shown in Fig. 2, the utility model is a kind of cup type air particle protective mask with one-way breather valve, comprises main body and ear band 6.Main body comprises outer field spunbond or needle punched non-woven fabrics 1, polypropylene melt-blown fibrous electret filter material intermediate filter layer 2 and spunlace non-woven cloth internal layer 3, along the weldering line ball 4 on mouth mask main ring edge, the weldering of skin 1, intermediate filter layer 2 and internal layer 3 is pressed into one by being located at.The position of main body upper limb central authorities is provided with bridge of the nose folder 5, and presss from both sides corresponding position at internal layer and the bridge of the nose sealing strip is set, contribute to mouth mask and better fit in wearer, play good protective action.Main body central authorities are outlet valve 7, effectively can reduce respiratory resistance.With adjusting button 8 and 9 on ear band 6, the length of ear band can be shortened, facilitate the people of different shape of face to use.
