Abstract
A protective cotton mask belongs to the technical field of the breath protective mask and comprises a cotton mask body and an elastic chalaza hung over the ears or the back head. The protective cotton mask is characterized in that the cotton mask body is respectively a surface layer made of non-woven fabric of 20 to 60g/m <2>, a filtering dustproof middle layer made of chemical fibre staple fibre, a purifying layer made of melt-blown cloth of 20 to 60g/m <2>, and an inner layer made of non-woven cloth of 20 to 40g/m <2> from the outside to the inside, the centre of the cotton mask protrudes forwards to form a cup shape, the edge joints each layer by an ultrasonic melt-joint method. The protective cotton mask solves the shortcoming of the prior art that the protective effect is bad, adopts multilayer compound, such as the non-woven cloth, the melt-blown cloth (INRI filter material), activated charcoal sheet material, chemical fibre staple fibre layer, etc., the dust resistant efficiency is high, and the repellency is good; the compound layer of the cotton mask is jointed by adopting the ultrasonic melt-joint, the appearance is beautiful and the joint is tight.
Description
Technical field
The utility model belongs to respiratory protection mask technical field, particularly has multi-layer combined filter body mouth mask.
Background technology
In manufacturing industry production, hospital and daily life, there are many particles and sensibiligen in the air, in order to stop particulates such as dust, pollen, bacterium, virus, wear cotton cloth respirator usually.Mouth mask of the prior art adopts gauze mostly, and protection effect is poor, and the difficult closely stickup of cotton gauze, and outward appearance is not attractive in appearance.
China utility model patent CN2794227 " mouth mask " (open day 2006.07.12) provide a kind of three layers of mouth mask, and the mouth mask sheet connects into whole mouth mask by cover body portion and ear's hot glue; The 25g/m that cover body portion is surface layer and internal layer by three layers of non-weaving cloth
2Spunbond cloth and middle level 30-40g/m
2Fusion spray cloth is combined into, and ear is that perforated film, spunbond cloth are combined into by two layers of non-weaving cloth, and ear establishes earhole.This scheme is by the compound mask material of forming of non-weaving cloth, the hot glue disposal molding, and production process is simplified, and efficiency improves, but three layers of non-weaving cloth, protection effect is poor.And the complicated material that takes of ear's design, cost improves.
Summary of the invention
Poor in order to overcome existing mouth mask protection effect, the inaesthetic problem of outward appearance, the utility model provides a kind of dust proof rate height, appearance looks elegant, protective mask that cost is low.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of protective mask comprises the mouth mask body and hangs over ear or occipital elastic frenulum, it is characterized in that the mouth mask body is respectively 20-60g/m from outside to inside
2The superficial layer that nonwoven is made is by the dustproof intermediate layer of the made filtration of staple fibre, by 20-60g/m
2The purifying layer that fusion spray cloth is made, 20-40g/m
2The nexine that nonwoven is made, the formation cup-shaped is protruded at mouth mask body center forward, and periphery engages each layer with the ultrasonic wave connection.
Described superficial layer and filtration also are provided with one deck is compound in nonwoven by micro activated carbon particle sheet material between the dustproof intermediate layer.
Described mouth mask nose fine strain of millet portion also is provided with the full aluminium nose clip that can arbitrarily adjust profile.
Described elastic frenulum is welded in mouth mask body both sides with the ultrasonic wave connection.
The utility model is with respect to existing protective mask, and beneficial effect mainly shows: 1 adopts nonwoven, fusion spray cloth (INRI filter material), active carbon sheet material, MULTILAYER COMPOSITE such as staple fibre layer, and the dust collection efficiency height, protective is good; 2, adopt ultrasonic bonding that the composite bed of mouth mask is engaged, appearance looks elegant is fitted closely.3, have the purifying layer that fusion spray cloth is made,, have interception, degraded, suction-operated, and purifying rate is up to 99.996% the carcinogenic invasions such as N-nitroso compound of industries such as chemical industry, rubber, coal.4, the mask nose bridge place establishes full aluminium nose clip, and is arbitrarily moulding during use, simple light and handy, and the driving fit of pack port cover body and face easily, wears comfortablely, and protection tightly.5, the formation cup-shaped is protruded at mouth mask body center forward, and is easy to process, smooth when depositing, and use can be to outer lug, comfortable wearing.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is an A-A place cutaway view among Fig. 1.
Fig. 3 is a ultra-sonic welded schematic diagram shown in Figure 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to protective mask shown in Fig. 1～3, by mouth mask body 1 with hang over ear or occipital elastic frenulum 2 is formed, mouth mask body 1 is respectively superficial layer 3 from outside to inside, activated carbon non-woven layer of cloth 4, filters the intermediate layer 5 of preventing dust, purifying layer 6, nexine 7.
Superficial layer 3 adopts 20-60g/m
2Smooth surface, the nonwoven that is difficult for laying dust do superficial layer.
Activated carbon non-woven layer of cloth 4 employing micro activated carbon particles are compounded in the sheet material on the nonwoven, make the utility model not only have the filtration dustproof effect, have also played the effect that purifies bad air.
Filter the staple fibre sheet material that use in dustproof intermediate layer 5, can play and filter dustproof and fill out thick effect.
Purifying layer 6 is 20-60g/m
2Fusion spray cloth, promptly the INRI filter material is made, and the INRI filter material has efficient purification particulate, and low-resistance performance 0.27～0.42 mean particle dia reaches more than 98% the purification efficiency of the utility model mouth mask.
Nexine 7 is 20-40g/m
2White nonwoven make, contact with face does not stimulate, non-secondary pollution is present respiratory protection desirable material comparatively.
The formation cup-shaped is protruded at mouth mask body 1 center forward, and periphery engages above-mentioned each layer along each point 1a shown in Figure 3 with the ultrasonic wave connection,
The utility model all adopts the ultrasonic technology produced with combination to form, and does not have and makes pin hole, and dust collection efficiencies such as weaving commonly used improve.
Outside or the inboard full aluminium nose clip 8 that is provided with random adjustment profile of mouth mask nose fine strain of millet portion, present embodiment adopts full aluminium nose clip 8, and is simple light and handy, and pack port cover body and face's driving fit easily, wears comfortablely, and protection is tightly.
