Abstract
The utility model provides a planar foldable mask. The planar foldable mask comprises a middle portion, a first portion, a second portion and a crease, the first portion is connected with the middle portion by a first welding line, the second portion is connected with the middle portion by a second welding line, the crease is used for symmetrically dividing the mask, and a plurality of folds are arranged on the middle portion. Filtering area of the mask is increased greatly while exhalation resistance is reduced due to the design of the folds. Additionally, wearing comfortableness of the mask is improved.
Description
Technical field
The utility model relates to a kind of mouth mask, is applicable to the air protection, is used for the dust particle of filtered air.
Background technology
Mouth mask is used to stop some harmful visible or sightless materials to filter for people's health designs, thereby can not come bad influence to human body.Mouth mask commonly used in daily life has the air filter-type respirator.In general, the mouth mask of this type comprises two kinds of citation forms---molded cup-shape or flat-folded shape.Cup-shaped mouth mask is normally molded to form, and between user's nose, mouth and mouth mask, forms with breathing chamber.Flat-folded mouth mask, for example C shape mouth mask can be folded into the plane when not using, and can form the protruding shape of opening when opening.This mouth mask is easy to use, can store easily.But expiratory resistance is excessive in use, often lets the people feel humidity and feel oppressed.
The utility model content
The utility model is excessive to existing flat-folded mouth mask expiratory resistance, in airtight breathing chamber easily moist with feel oppressed, cause the uncomfortable problem of user, provide a kind of and can effectively reduce the flat-folded mouth mask mouth mask expiratory resistance, comfortable wearing.
The technical scheme that the utility model solves its technical problem is: a kind of flat-folded mouth mask; Comprise mid portion, pass through the first that first sealing wire is connected with mid portion; The second portion that is connected with mid portion through second sealing wire, and the folding line that the mouth mask symmetry is separated; Said mid portion is provided with some folds.
Said first sealing wire and said second sealing wire mutually disjoint in the mask main body scope.
Said mid portion is a filter course.
Said filter course is the melt-blown nonwoven layer of cloth.
Said mid portion also comprises the shape layer that is distributed in the filter course both sides.Said shape layer is the spun-bonded non-woven fabrics layer.
The fold of said mid portion is vertical or horizontally disposed, is preferably vertical setting.
The position of the corresponding eye of the top edge of said first is provided with an arc-shaped recess.The shape of preferred arc-shaped recess and lower part of eye is consistent.
The madial wall of said first be provided with one extend to two tails flexible layer.Said flexible layer is a spongy layer, can increase mouth mask top edge and facial sealing, prevents that the hot gas of breathing out from fog glasses.
C type mouth mask of the present invention is divided into three parts that are welded to each other, and mid portion is folded into some folds, because mid portion is folded into some folds, has increased the filter area of mouth mask greatly, has reduced expiratory resistance.Improved the comfort when putting on mouth mask.
The eye of mouth mask below is provided with depression in the utility model preferred implementation in addition, makes mouth mask tightr with facial sealing, and the mouth mask edge can not push up, injure under-eye skin, dresses more comfortable.
The spongy layer that the madial wall top edge of mouth mask is provided with in the utility model preferred implementation not only can further increase mouth mask and facial sealing, can also prevent that the hot gas that the people breathes out from making glasses fuzzy.

The specific embodiment
First 2 as shown in Figure 1, that a kind of flat-folded mouth mask comprises mid portion 1, is connected with mid portion 1 through first sealing wire 4, the second portion 3 that is connected with mid portion 1 through second sealing wire 5, and the folding line 7 that the mouth mask symmetry is separated; Said mid portion has some folds 6.When mouth mask was opened, fold can increase the specific area of mouth mask, reduced the expiratory resistance of mouth mask relatively.As shown in Figure 2, the mid portion 1 of present embodiment mouth mask is one or more layers filter course 101, and filter course 101 is melt-blown nonwoven layer of cloths commonly used in the mouth mask, can also be the melt-blown nonwoven layer of cloth of electret melt spraying non-woven fabrics filter course or static electrification.Said mid portion 1 also comprises the shape layer 102 and 103 that is distributed in the filter course both sides.Shape layer 101 and 102 is spun-bonded non-woven fabrics layers.Other layer also can be set, like activated carbon layer 104 between 101 and 102.In order to enlarge the specific area of mid portion as far as possible, first sealing wire 4 and second sealing wire 5 in the present embodiment mutually disjoint in the mask main body scope.As shown in figures 1 and 3, the position of first's 2 corresponding eyes of the utility model mouth mask is provided with an arc-shaped recess 8.The shape of preferred arc-shaped recess 8 and lower part of eye is consistent.As shown in Figure 4, split folding line 7 and form by 701,702 and 703.701 and the 702 crossing angles that form 140-150 °, 702 and 703 intersect the angles of 135-150 ° of formation, and in order to let mouth mask meet Chinese shape of face structure, this angle of implementing preferred 701 and 702 formation is 140 °, and the angle of 702 and 703 formation is 135 °.
Said mouth mask as shown in Figure 4 also is provided with nose clip 10.The madial wall of said first be provided with one extend to two tails flexible layer 11.Said flexible layer is a spongy layer, can further increase mouth mask top edge and facial sealing, prevents that the hot gas of breathing out from fog glasses.Flexible layer 11 can be and is made as vertical bar shaped as shown in Figure 3, also can be set to the shaped form that is provided with depression as shown in Figure 5.11 preferred shapes as shown in Figure 5 of present embodiment can make face shield closer with facial cooperation.
