Below the technical solution of the utility model is made further explanation:
In order further to improve the filter effect of mouth mask filter disc, the present invention proposes the mouth mask filter disc of a kind of high efficiency filter PM2.5.This mouth mask filter disc is on the basis of conventional rectangle, done a series of distortion, its in four limits be arc or oval-shaped rectangle at least on one side, a limit that is included in rectangle is that two relative limits of arc or ellipse, rectangle are that two adjacent limits of arc or ellipse, rectangle are arc or ellipse, and three limits of rectangle are that four limits of arc or ellipse or rectangle are arc or oval these five kinds of situations.And the length of arc chord length equals the length of rectangle or high length, or the length of oval-shaped axle or the string parallel with axle equals the length of rectangle or high length.Further preferred situation is: two relative limits of rectangle are arc or ellipse, and arc action is rectangle length or height 1/8～1 times, preferably 1/4～1/2 times; The length of the semiaxis that described ellipse is vertical with rectangular edges is rectangle length or height 1/8～1 times, preferably 1/4～1/2 times.Mouth mask filter disc of the present invention can be adjusted according to different mouth mask shape and shape of face, thereby meets to greatest extent the needs in market.
The beneficial effect that technical scheme of the present invention is brought is:
Mouth mask major part in the market does not have the effect of filtering PM2.5, and inventor, by research, invents a kind of filter disc that can effectively filter PM2.5, this filter disc is positioned in common mouth mask, just can play the effect of filtering PM2.5, simultaneously cheap, consumer is received more tangible benefits.The filter disc that the utility model adopts is three layers or four layers of composite construction, can increase the filter effect of filter disc to pellet, and further preferably polypropylene spunbond nonwoven internal layer and the outer field grammes per square metre of polypropylene spunbond nonwoven 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
2; Further preferably, polypropylene spunbond nonwoven internal layer and the outer field grammes per square metre of polypropylene spunbond nonwoven are for being respectively 30g/m
2, polypropylene fibre melt spraying non-woven fabrics intermediate layer grammes per square metre is 25g/m
2, active carbon layer grammes per square metre be 40g/m
2, total grammes per square metre is 125g/m
2.Active carbon layer can increase adsorption effect.Skin and/or internal layer polypropylene spunbond nonwoven can be selected fragrant, increase user's joyful sense.This is due to the nonwoven polypropylene fabric filter disc that adopts this thickness, make filter disc there is good particle filtering efficiency, can reach NIOSH(American National employment security health research institute) effect of N95 type mouth mask, in to the testing process of PM2.5, filter disc of the present utility model is not less than 95% to particle filtering efficiency, and can reach 99%.Filter disc of the present utility model has good aeration, at gas flow, is in 85L/min situation, and the inspiratory resistance of filter disc is 210～270Pa.Comfort level when the ventilative degree of mouth mask has determined to wear, the poor mouth mask of gas permeability can be in mouth mask, water smoke is formed on surface, of long duration may multiply bacterium, and as poor in the gas permeability of mouth mask, a lot of weakly old men, child and patient, all should not wear, so in the particle filtering efficiency while that guarantees mouth mask, guarantee that gas permeability is only the key of product.Some expensive, baroque masks, face shield, its gas permeability is poor, is unsuitable for people and uses in daily life and wear.Also there is ventilative poor shortcoming in the medical yarn mouth mask of 12～16 layers.
The utility model passes through the optimization of filter disc to select, thereby makes filter disc of the present utility model have filter effect and gas permeability concurrently, is the good selection of people's daily life protection PM2.5.Filter disc of the present utility model can be used in conjunction with the mouth mask that is designed with socket, also can be used in conjunction with common mouth mask, thereby can make the common mouth mask in consumer's hand become the mouth mask that can effectively protect PM2.5.Mouth mask filter disc of the present invention is three-decker, is respectively polypropylene spunbond nonwoven skin, polypropylene fibre melt spraying non-woven fabrics intermediate layer and polypropylene spunbond nonwoven internal layer, or between skin and intermediate layer or between internal layer and intermediate layer, is being provided with layer of active carbon layer.Thereby make it have the effect of effective filtration PM2.5.
After the structure of mouth mask filter disc is in optimized selection, originally novel have pair shape of mouth mask filter disc to carry out the research of a dark step, and find, by the edge designs of mouth mask filter disc, be ellipse or arc, can further improve the filter effect of mouth mask filter disc, greatly reduced flowing of the space of air-flow by mouth mask and nose, thus the filter effect of more effective performance mouth mask filter disc structure to PM2.5.Under same circumference, area of a circle maximum, thus the effect of filtering is best, so this mouth mask filter disc is made it, when supporting the use with mouth mask, to make largeizationr of filter effect.Mouth mask filter disc of the present invention, because it has the outer of ellipse or arc, thereby more even while making respiratory air flow pass through filter disc, wearer breathes more smooth; And more press close to shape of face, filter effect is better.
In order further to make mouth mask filter disc laminating face, the right and left after the doubling of mouth mask filter disc is adhesively fixed in top margin along broken line, the length of the canned paragraph 5 along top margin of the formation that is adhesively fixed is 1～8 millimeter, more preferably 1～6 millimeter, more preferably 1～4 millimeter; A thereby obtuse angle of fixing formation after mouth mask filter disc is folded, thereby it is more applicable for is positioned in three-dimensional mask, laminating face more, fix a bit of distance, thereby the space that can stop air-flow directly to form from nose top is passed through after the top margin central authorities doubling due to mouth mask filter disc.Or by after the doubling of mouth mask filter disc, from top margin along broken line to upper 1/3～1/2 of broken line formation " V " the type flanging that is adhesively fixed, on the mouth mask filter disc of stick portion after doubling, form upper 1/3～1/2 place take broken line as summit, bonding zone 6 take the top margin of mouth mask filter disc as the acute triangle on base, the length on bonding zone base 7 is 1～8 millimeter.Thereby make more fit face and can stop air-flow to pass through from nose top of mouth mask filter disc, increased filter effect.
When being used, consumer can adjust according to the demand of oneself size of mouth mask filter disc, this novel cementing line forming according to bonding multilayer mouth mask filter disc is set to many, and more preferably 3～5, thereby consumer can shear along cementing line, be cut into the applicable size of oneself using.Distance between cementing line is 1～5 millimeter.Thereby mouth mask can be designed to a kind of size, and by the shearing between cementing line, adjust the size of mouth mask filter disc.Thereby make the size of mouth mask more adapt to everyone specific requirement, the laminating face of hommization more.In this novel optimal technical scheme, in the upper and lower scheme with arc-shaped protrusions, can be by shearing the length of the rectangle in mouth mask filter disc as to be adjusted to 6cm from 15cm, preferredly from 13cm, be adjusted to 10cm; And the action of mouth mask filter disc arc-shaped protrusions can be adjusted to 1cm from 6cm, and preferably from 3cm, be adjusted to 1.5cm.
