Do further explanation and explanation in the face of the technical scheme of the utility model down:
A kind of three-dimensional mask that can effectively filter PM2.5; Described mouth mask is made up of mouth mask sheet portion, the pressure nose that is positioned at mouth mask sheet portion top, contraction flow region and the frenulum that is positioned at mouth mask sheet subordinate side; Described mouth mask sheet portion, press nose and contraction flow region to comprise three-decker; Be respectively by warming layer outer, that constitute by insulation cotton and the nexine that constitutes by weaving face fabric; Between internal layer and warming layer, be provided with compound nonwoven polypropylene fabric filter disc, and the socket that at least one is convenient to the filter disc filling or changes be set at internal layer.
Wherein, Three-dimensional mask of the present invention is by pressing nose, sheet portion and contraction flow region to constitute the projective structure of a solid, the muffle portion that comprises the people that can be good, and after hanging over ear by frenulum; Wherein frenulum can be selected various bungees for use; The fixture of an adjusting bungee length also can be installed, fixing with better, the convenient use.Also can select tatting, knitting for use by outer field lining, plain color, stamp, cotton, polyester-cotton blend etc., and preferred antibiotic facing material.
Take, replace filter disc for ease, preferred socket is two, is symmetricly set in the left and right sides side of filter disc.Thereby can be after socket be on one side put into, in the spigot adjustment of another side.
Comfortable in order to use, and make filter disc in interlayer, be difficult for being subjected to displacement, the area of the mouth mask sheet portion internal layer between preferred two sockets is greater than or equal to the area that the nonwoven polypropylene fabric filter disc is dissolved in spray, thereby makes the lining of mouth mask internal layer shelter from filter disc fully.
The compound nonwoven polypropylene fabric filter disc that the utility model adopted is a three-layer composite structure, is respectively polypropylene spunbond nonwoven skin, polypropylene fibre melt spraying non-woven fabrics intermediate layer and polypropylene spunbond nonwoven internal layer.Three-layer composite structure of the present invention can increase the filter effect of filter disc to pellet, and further preferred polypropylene spunbond nonwoven internal layer and the outer field grammes per square metre of polypropylene spunbond nonwoven are for being respectively 30g/m
2, the grammes per square metre in polypropylene fibre melt spraying non-woven fabrics intermediate layer is 25g/m
2, total grammes per square metre is 85g/m
2This is owing to adopt the compound nonwoven polypropylene fabric filter disc of this thickness; In conjunction with other structures of three layers of mouth mask; Make mouth mask have good particle filter efficiency, can reach the effect of NIOSH (American National employment security health research institute) N95 type mouth mask, in testing process PM2.5; The novel mouth mask of this use is not less than 95% to the particle filter efficiency, and can reach 99%.The mouth mask of the utility model has excellent air permeability, is under the 85L/min situation at gas flow, and the inspiratory resistance of mouth mask is 280～210Pa; Comfort level when the ventilative degree of mouth mask has determined to wear; The mouth mask of gas permeability difference can be in mouth mask, water smoke is formed on the surface, of long duration may multiply bacterium, and poor like the gas permeability of mouth mask; A lot of weakly old men, child and patient; All should not wear, so in the particle filter efficiency that guarantees mouth mask simultaneously, guarantee that gas permeability is only the key of product.Some cost an arm and a leg, baroque mask, face shield, and its gas permeability is poor, is inappropriate for people and uses in daily life and wear.And also there is the shortcoming of ventilative difference in the medical yarn mouth mask of 12-16 layer.
The utility model passes through the optimized choice to filter course, thereby makes the mouth mask of the utility model have filter effect and gas permeability concurrently, is the good selection of people's daily life protection PM2.5.
