Abstract

The utility model discloses a gauze mask of high gas tightness, it relates to gauze mask gas tightness technical field, the gauze mask top edge outside sets up a stub, and this stub has been undertaken the gauze mask area and has been geared to the needs of the job and covers the pulling force at edge, thereby has solved when wearing the gauze mask top edge and expanded the unable problem that laminate the face by tensile under gauze mask area tensile force, simultaneously, pulling force with the gauze mask area of bearing short line turns into the pressure to the bandage, and this pressure makes gauze mask top edge and face closely laminate, can bear great breathing pressure and not in bridge of the nose both sides gas leakage. The utility model discloses beneficial effect does: it can make the inseparable laminating of the inboard top edge of gauze mask and the person of wearing face, has simple structure, reasonable in design, cost of manufacture low grade advantage moreover.

Description

A kind of mouth mask of high-air-tightness

Technical field

The utility model relates to mouth mask air-tightness technical field, is specifically related to a kind of mouth mask of high-air-tightness.

Background technology

Mouth mask on open market is the bubble-tight problem of ubiquity when actual wear, causes the actual effect of mouth mask obviously to reduce.Usually, under the effect of respirator belt, the mouth mask at cheek and chin place mates with face contour better, fit tight.In nose and two side areas thereof, face contour big rise and fall, the tall bridge of the nose and both sides cheekbone play the effect of fulcrum, and under the effect of respirator belt pulling force, the oral mask portion between the bridge of the nose and cheekbone has the trend be straightened, and cause mouth mask and bridge of the nose both sides to occur gap.In addition, the breath pressure that during expiration, mask body diverse location bears is almost identical, but the pulling force effect of respirator belt that mouth mask top edge is subject to is minimum, and therefore, during expiration, mouth mask top edge is the place the most easily occurring to leak gas.So bridge of the nose both sides the most easily gas leakage occur when wearing mouth mask and the most serious position that leaks gas.Bridge of the nose both sides, mouth mask top leak gas, and not only reduce the protection effect of mouth mask, the puzzlement of people with glasses during low temperature environment especially.

In addition, have the mouth mask that the doubling of nose clip is received, when launching to wear, in an angle, this angle causes nose clip can not fit tightly with bridge of the nose top profile to the easy shape in nose clip fold position, causes during breathing and leaks gas in this angle.

Utility model content

The purpose of this utility model is to provide a kind of mouth mask of high-air-tightness, and it can improve the close fitting of top edge and wearer's face inside mouth mask.

In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it includes mouth mask top edge, short-term, nose clip, respirator belt, Detachable connection structure; Short-term is arranged at outside mouth mask top edge, and mouth mask top edge is provided with nose clip, and short-term two ends are provided with Detachable connection structure, and respirator belt is arranged at mouth mask both sides of the edge.

Described nose clip length >=8cm, close to human face's width; Bending diameter >=the 2mm of nose clip doubling; The spacing of nose clip two ends and respirator belt tie point on mouth mask is 0-1cm.

When described short-term is non-elastic material, the half length of short-term than the fixing point of short-term on mouth mask to the little 2 ~ 15mm of the distance of mouth mask horizontal direction medium line.

When described short-term is elastomeric material, the half length of short-term than the fixing point of short-term on mouth mask to the little 4 ~ 30mm of the distance of mouth mask horizontal direction medium line.

Adopt after said structure, the utility model beneficial effect is: the short-term in the present invention assume responsibility for the pulling force of respirator belt to mouth mask top edge, solves nose clip when wearing and to be stretched under the effect of respirator belt pulling force expansion thus the problem of the face that cannot fit; Meanwhile, it is tightr that the pressure of short-term to nose clip makes mouth mask top edge and face fit, and can bear larger respiratory pressure and not leak gas in bridge of the nose both sides, and having the advantages such as structure is simple, reasonable in design, cost of manufacture is low.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Description of reference numerals:

1-mouth mask top edge; 2-short-term; 3-nose clip; 4-respirator belt; 5-Detachable connection structure.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, this detailed description of the invention adopts following technical scheme: it includes mouth mask top edge 1, short-term 2, nose clip 3, respirator belt 4, Detachable connection structure 5; Short-term 2 is arranged at outside mouth mask top edge 1, and mouth mask top edge 1 is provided with nose clip 3, and short-term 2 two ends are provided with Detachable connection structure 5, and respirator belt 4 is arranged at mouth mask both sides of the edge.

Described nose clip 3 length >=8cm, close to human face's width; Bending diameter >=the 2mm of nose clip 3 doubling; The spacing of nose clip 3 two ends and respirator belt 4 tie point on mouth mask is 0-1cm.

Described short-term 2 is that line, rope, band etc. are made into, and material can be non-elastic material, also can be elastomeric material:

(1) when short-term 2 is non-elastic material, the half length of short-term 2 than the fixing point of short-term 2 on mouth mask to the little 2 ~ 15mm of the distance of mouth mask horizontal direction medium line.

(2) when short-term 2 is elastomeric material, the half length of short-term 2 than the fixing point of short-term 2 on mouth mask to the little 4 ~ 30mm of the distance of mouth mask horizontal direction medium line.

In the middle of the nose clip 3 and near mouth mask on some fluctuatings point is set, as the point of adjustment of short-term 2 tensile force.By regulating the diverse location of short-term 2 at bridge of the nose place, the arcuate shape that can change nose clip 3 and the pressure size being delivered to arc nose clip 3 and distribution, and can the different shape of face of flexible adaptation.

Short-term 2 two ends and mouth mask can be fixedly connected with, and also can be that one end is fixedly connected with, and the other end adopts hook, thread gluing etc. to removably connect 5, can also be two ends are all removably connect 5.

The operation principle of this detailed description of the invention is: when wearing mouth mask, first mouth mask top edge 1 and wearer's face outline is made with finger extruding nose clip 3, then short-term 2 is hung near the nose clip 3 on the bridge of the nose, like this, short-term 2 and nose clip 3 just define two arc.The pulling force of the respirator belt 4 that short-term 2 bears is converted into the pressure to nose clip 3, this pressure dissipation is pressed to face in whole cambered surface by now curved nose clip 3, thus mouth mask top edge 1 and face are fitted tightly, and larger respiratory pressure can be born and do not leak gas in bridge of the nose both sides.

The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
