Description

A kind of disposable breathing mask

Technical field

The utility model is related to a kind of disposable breathing mask, especially it is a kind of have prevent the disposable of both sides alice and gas leakage Mask.

Background technology

The disposable breathing mask sold on the market folds disposable non-woven cloth mouth especially with the most traditional rectangle of amount Cover, is essentially all the intermediate rectangle non-woven fabrics gauze mask for having 3 Z-types to roll over, and the national standard specification of this mask is usually 95mmX175mm is pulled open not less than 150mm up and down, as shown in Figure 1, this mask is really very simple, speed of production is fast, cost Low, use is also very convenient, because of these advantages, using also very extensive.

But this traditional disposable 3 folding mouth mask also has its obviously several drawback, it is main also in that this The simple construction feature of kind mask itself and material characteristics, cause mask body periphery and facial docile degree is not high, leakproofness Not enough, it is easy gas leakage, therefore causes at least following three points defect.

First point, be exactly that mask body tightness at the bridge of the nose is inadequate, is easy deflation, gas leakage, nasal fossa 4 as shown in Figure 2 It sets, although generally there is deformable nose bridge batten 3 at the bridge of the nose, the construction features of existing this traditional disposable breathing mask ontology And the stress of working method and nose bridge batten material itself is unable to this simply and easily mask of radical change with yield force Air-tightness, is easy gas leakage when air-breathing, and gas leakage obviously will influence the filter effect of mask itself, and expiration when is also easy to run Gas, especially in winter, the hot gas leaked out at nasal fossa 4 can make the eyeglass of the user to wear glasses generate fog, seriously affect sight, Influence safety.

Therefore, so for many years, have much for this disposable breathing mask prevent from the breathing out scheme of hot gas leakage, Wo Menmai Many such disposable breathing masks, also retrieved it is related be related to anti-hot gas, breathe out, the mask patent of fog, condensing gas, have more It is essentially all to install, paste and be arranged some at nose bridge batten similar to protrusion, prominent knot up to nearly hundred patent applications The accessory structure of structure, binding, long strip etc., these methods can only all be the increase in production cost, increase production stage, Actually all without what practicability, poor operability, what even basic no operability of some, unsuitable scale Production, for disposable breathing mask pocket-handkerchief so simple in this way, without practical significance, so so for many years, market On still or only this simple disposable breathing mask.

Second point, be exactly mask both sides tightness it is inadequate, it is easy to become flat, gas leakage, to find out its cause, be actually this Caused by the geneogenous structure feature of kind mask, this folding mouth mask is all the Z-fold portion of 3 10mm in centre or so, such as Fig. 1 It is shown, but when mask is pulled open by about 5 ear band, folded portion will be launched into M type waveforms naturally, because folding Portion is higher, and the Wave crest and wave trough difference in height generated after expansion will be bigger, because expansion is so that be the mask both sides of straight line originally Edge sealing, which will be bent, becomes arc-shaped curved surface, and material bending makes the edge sealing of mask tilt outward at the stress that curved surface generates, institute With you notice observation just it will be seen that the both sides for having on disposable breathing mask traditional in this way are essentially all tilting, and Taobao searches for one Under, all model's pictures for wearing such disposable breathing mask are all absolutely to tilt.The edge sealing of tilting is not enough to push down envelope The M types gap that firmly Wave crest and wave trough of folding part is formed, so gas leakage is inevitable.

Because of the geneogenous construction defect of this disposable breathing mask so that the actual filtration effect of this mask is just beaten greatly Discount, it is many always using crowd because it is simple and convenient, although so many people attempt to change for many years, but Never people can really change.

Thirdly, this mask generally uses non-woven fabrics, and material is than relatively thin, when even having 3 folding parts to open Can be as certain support, but support force or far from enough is especially short of breath and the time soaks with carbonated drink Afterwards, it is easy to attach on lip when air-breathing, significantly reduces comfort when people use.Therefore also someone tastes Examination changes, and in centre plus one section of backing material, we also queried related patents, is all because simple disposable small in this way Production cost is increased on product, increases extra production stage, is needed to increase many people to complete, it is operable in production process Property is not high without practical value, so these improvement are not all realized really, we respect each people having the courage to bring forth new ideas, but There is no real operability, not the fantasy of practical value, virtually free from meaning, therefore, uses on the market most Be still this disposable breathing mask for having drawback.

So above three drawback is actually because of the geneogenous fault of construction of this disposable 3 folding mouth mask and material Caused by material feature so that the filter effect of this disposable breathing mask is had a greatly reduced quality, but its usage amount it is very big also in that it The congenital advantage having, it is simple, conveniently, it is economical, practical, also have certain effect if it is with regular good product.

Utility model content

It creates and changes the mankind, innovation service society, the most simple most economical most practical approach of use changes it, it is allowed preferably to take Be engaged in the public, is based on this theory, this utility model is bad mainly for above-mentioned disposable breathing mask periphery air-tightness, and there are gas leakage Defect, any cost and production process need not be increased by originally using, and very simple and practical easily method is effectively Solves the puzzlement of industry for many years.

Nearly all such traditional disposable breathing mask is all that tradition is disposable shown in B1 in Fig. 1 and as shown in Fig. 5 Shown in the folding schematic diagram B11 of mask B1 and B1, substantially all is all in middle there are one fold domain, and it is general all 3 Z-fold portions, each fold in 10mm or so, overall width 95mm or so, be exactly because of this congenital structure feature, As shown in Fig. 2, the hot gas for causing exhalation is easy to scurry out from the position of nasal fossa 4 and from both sides gas leakage to influence filter efficiency Defect.

By repetition test, the utility model is off the beaten track, folded portion has been carried out unconventional setting, that is, one Increase a folding part at the secondary property mask bridge of the nose corresponding when wearing, so that it may easily solve what hot gas was scurried out with very simple Puzzlement.

C1 as shown in Figure 3 is disposable more folding mouth masks described in the utility model with anti-breath function, and first folds Portion 11 is exactly the position increase of the unfolded between first folding part 21 of traditional disposable breathing mask B1 and nose bridge batten 3 One folding part.Fig. 5 be traditional 3 fold disposable breathing mask B1 and its fold schematic diagram B11 and C1 described in the utility model and It folds the folding position position versus figure of schematic diagram C11, is illustrated in figure 6 the folding of disposable breathing mask C1 described in the utility model Folded schematic diagram C11, for convenience of description, by each fold portion number consecutively from top to bottom, the number in figure is the utility model institute It is naming each position stated on disposable breathing mask C1.

Each folding part is 11 successively from top to bottom, 21,22,23...., the bridge of the nose of the folding part 11 on mask top Under press strip 3, from the mask body upper edge 8-30mm or so place, at preferably 10-25mm, setting 1-11mm or so Z-type foldings Portion 1-3 folded, preferably folding parts 6-10mm 1, the folding part Uniform Name of described this at the bridge of the nose is by this explanation Bridge of the nose folding 11, is a kind of meaning really changed for increased this is explained in more detail to seem simple folding part, by nose Each position of beam folding 11 carries out refinement name to facilitate statement.

The fold line of the folding bridge of the nose folding 11 has two, respectively the visible fold line 111 in outside, inner face fold line be Invisible foldable line 112；There are 3 faces, the folded portion of 11 outside of bridge of the nose folding, i.e., from 111 or less fold line in each Z-fold portion It is named as front domain 113 to the face domain between the fold line 212 of folding part 21, among the folding part between fold line 111 and 112 Folded portion be in face domain 114, rearmost folded portion from fold line 112 to nose bridge batten 3 face domain name For domain 115 below.Likewise, the visible fold line of folding part 21 is named as 211, invisible foldable line is 212, before domain be 213, the intermediate fold plane domain domains Zhong Mian are 214.

As shown in figure 5, B11 is the folding schematic diagram of the disposable 3 folding mouth mask B1 of tradition shown in Fig. 1, the disposable mouth of tradition 3 folding parts of cover are essentially all in middle, and C11 is the folding schematic diagram of the utility model mask C1 shown in Fig. 3, figure The example continuously folded and the comparison of the method for folding of traditional disposable breathing mask folding part for being shown as the utility model are illustrated Figure.

A simple bridge of the nose folding 11 directly is designed in the location of bridge of the nose, it is very simply very common in this way to set It is very unique design instead that meter, which is completely unusual in fact, wherein there are five significant very useful benefits.

First, bridge of the nose folding 11 particularly simple solves traditional disposable breathing mask hot gas and is easy to scurry out and generates mist on glasses Gas perplexs.

According to the conventional program for wearing the disposable breathing mask, the folded portion of mask is pulled open up and down, and band muzzles, pressed The nose bridge batten 3 is pressed, as shown in figure 4, at this moment the wave crest of 11 expansion of bridge of the nose folding is exactly fold line 111, trough is exactly to roll over Superimposing thread 112, in this way, by the front and back support in middle face domain 114, trough fold line 112 is just bent docile at nasal fossa so that the bridge of the nose Mask body part among press strip 3 and the bridge of the nose folding 11 i.e. below domain 115 just completely bending docile the bridge of the nose, nasal fossa 4 and At pouch, and at this moment the middle face domain 114 at nasal fossa 4 almost with the bridge of the nose, nose bridge batten 3 domain 115 below, the bridge of the nose folding 11 wave Domain 113 all constitutes abrupt slope shape inclined-plane before on peak, and portion is equivalent to so even close to vertical plane in mask exhibition A wall is formd at the nasal fossa for the mask cavity and the bridge of the nose that mask body is formed by bending when opening, just blocks the hot gas of exhalation It scurries out to from nasal fossa, the hot gas to simply and effectively solve very much exhalation is scurried out forms the puzzlement of fog on eyeglass.

And this to be also exactly traditional centre 3 fold the indeterminable problem of disposable breathing mask because such centre 3 folds Mask is pulling open folding part, and when to which mask body be unfolded, their nose bridge batten 3 arrives the fold line 211 of folding part 21 Intermediate face domain 213 is substantially flat, tradition disposable breathing mask wearing state as shown in Figure 2, the face domain 213 and mask body Other faces domain formed is common cavity, when exhaling, the positive pressure generated in cavity just pushes face domain 213 open outward, The gap between mask body and nasal fossa is more pulled open so that hot gas is scurried out unblockedly from nasal fossa, and this practicality is new The middle face domain 114 of the bridge of the nose folding 11 of type just forms a wall and blocks scurrying out for hot gas, and when expiration in mask cavity When domain 113 moves out before the positive pressure expulsion of generation, two faces of fold line 111 are just axle center with fold line 111 Opening and closing have unloaded this outside thrust, and this face domain 213 of traditional mask is pushed open outward by rigid linkage, Thus, the drawbacks of this hot gas is easy to scurry out is the congenital fault of construction of all such disposable 3 folding mouth masks of tradition Caused by, it is therefore desirable to the change that essence is carried out in structure, it is new in this this practicality that mask body is topmost increased by Bridge of the nose folding 11 described in type, it will be apparent that change mask body upper part cavity body structure feature and loading characteristic.

By particularly simple method, as soon as increasing a slight folding in the nose bridge, the utility model is very light Loose ground solves the puzzlement of many people so for many years, is a kind of very useful change.

Second, air inlet area when bridge of the nose folding 11 improves air-breathing, reduces expiratory resistance.

Just as stated earlier, traditional disposable breathing mask rolls over 11 design due to no bridge of the nose described in the utility model, such as Shown in Fig. 2, on the cheek that the negative pressure that generates upon inhalation can make mask body be adsorbed near cheekbone, waste natively not Big effective filtration area, it will be apparent that reduce effective air inlet area, to increase respiratory resistance.

And the utility model because have the bridge of the nose folding 11 well-designed, the middle face domain 114 as standing wall, support Play front domain 113 so that middle face domain 114 and 111 filter area below of fold line have obtained effective utilization, even exist Under negative pressure state when air-breathing, but also the front domain 113 is always at overhead support surface state, rather than as traditional primary Property mask in the face domain 213 of same position be the curved surface for curving inwardly and almost touching cheek, to effectively maintain cheekbone The usable efficiency of mask body is more fully utilized in air inlet area near bone at cheek, compares traditional disposable breathing mask, Be the equal of increasing effective admission area, to reduce respiratory resistance.

Third, the bridge of the nose folding 11 opened can significantly alleviate the pressure of the bridge of the nose.

Traditional disposable breathing mask is since 213 part of face domain of mask body is entirely flat, as shown in Fig. 2, even if opening The cavity that the first folding part 21 is formed by bending afterwards can form certain radian space at the bridge of the nose, but in the drawing of 5 elastic force of ear band Under dynamic, this face domain is also to be pressed on the bridge of the nose with entirely having no buffering, and to the bridge of the nose, nose, there are one apparent pressure, especially It is Roman nose user, pushing down nose for a long time influences the aeration of nose, influences very much the user experience of mask, so many people are not Like wearing masks, this is also one of factor.

And bridge of the nose folding 11 described in the utility model is since just at the bridge of the nose, the folded portion after expansion is equivalent to a Z Type spring, formed a loose folding buffer memory, the pulling force of ear band be buffered by folded portion it is after-applied on the bridge of the nose , the pressure of bridge of the nose nose is considerably reduced, it therefore, can be thereby according to the crowd characteristic of user group, adjustment bridge of the nose folding 11 Width, produce a variety of different specifications, to adapt to different crowd and race, such as the white people of Roman nose, in this way Can more hommization, this is not easily achieved in traditional disposable breathing mask.

Fourth, bridge of the nose folding 11 is so that the both sides of mask upper edge are slight curving downwards so that the exposing area under canthus is more It increases wealthy.

For traditional disposable breathing mask since the first folding part 21 is remote from top edge, folding part 21 there is not the top edge of mask body The active force for having drop-down, top edge is substantially positioned on same plane when wearing, and top edge just may resist or cover Firmly under eyelid at pouch, the user of especially small shape of face and the big user of pouch resist and are certain to not very comfortable, this practicality is new Type is close with the top edge of mask body due to there is the folding of the bridge of the nose folding 11, can be effectively when mask pulls open Reduce the height of top edge so that there are one downward folding is curved on the both sides of the top edge of mask body described in the utility model Qu Liang, 42 pointed location as shown in Figure 4, effectively expands the space of face under eyes, reduces to resisting pressure under eyes Power is the beneficial improvement of a comparison, user especially big to small shape of face user and pouch.

Fifth, the folding of bridge of the nose folding 11 reduces the width on mask body both sides, the sealing on mask body both sides is increased Degree.

Mask body described in the utility model can also use the material of same width, the width being unfolded after pulling open up and down in this way Degree will be identical with traditional disposable breathing mask, and the width of finished product can also keep original standard 95mm width after folding, Each fold part overall width is reduced, but in the case of same widths because a more folding part it is necessary to The corresponding width for reducing folding part, the width of folding part reduce the supporting role that can accordingly reduce counterpart cover chamber body too much, therefore Mask overall width is preferably reduced 10mm or so by disposable breathing mask described in the utility model, marginally reduces the width of folding part Degree, finished product overall width is in 85mm or so, but developed area is essentially identical.

Beneficial benefit improved in this way is exactly that the height fall of Wave crest and wave trough reduces, and pulls open rear folding part in mask The compactness of both sides and cheek can increase, and mask both sides are narrower, also can therefore be improved with the compactness of cheek, although National standard is 95mm wide, but in fact pass through the utility model be transformed, keep pull open width it is certain under the premise of, it is slightly narrow Some effects can be more preferable, especially the user to small shape of face, although traditional mask can also make multiple specifications, in fact at The disposable breathing mask traditional in this way that year people uses is most or only there are one conventional specifications.Although national standard finished product is not Spreading width is 95mm wide, but in practice for vast majority of people for, the ear band that the width of ear hangs up mask is not enough to The width for pulling open 95mm can not draw away the side of this width, and docile degree is not certainly just high, this is also that mask both sides tightness is not high One major reason.

The width of folding part can also be reduced under the requirement for keeping conventional width, certain number of folds is more, while also dropping The low height of folding part, therefore the support force of counterpart cover chamber body can be also reduced, for this problem, the applicant also has very simple Single practical and operational good solution, it will be additionally carried out separately apply on this question.

The drawbacks of being easy gas leakage for aforementioned conventional disposable breathing mask both sides, be easy to tilt, the utility model uses ingeniously The method of wonderful segmentation bevel edge, and without increasing any cost without increasing any process, and simply easily solves very much It has determined the above problem.

That traditional disposable breathing mask B1 as shown in Figure 1, the pressing on mask body both sides or suture sideline use is all 2-4 The rectangular lattice edge sealing of dotted straight lines composition, entire edge sealing are the rectangular lattice envelopes of strip made of being pressed by these dot matrix Side, for the edge sealing of pressing because multilayer mask body material bonds together and is hardened, the length of side on both sides is basically not stretch It pulls open to open up above and below mask body such as the sideline 71,72 of edge sealing in Fig. 8 in the sideline of the equal regular length of contracting When opening cover forms cavity, the B1 wearing effects figure as shown in Fig. 2, Fig. 8, wherein Fig. 8 is edge sealing position amplification on the right of Fig. 2 Figure, the edge sealing will be in the arc-shaped with face's natural torsion, and the inner edge 71 of edge sealing is naturally just at the outer arc of circular arc, outside Just at inner arc, however because the inside and outside side line length of edge sealing is equal, two edge sealing lines have the spacing of nearly 1cm, institute again in sideline 72 Can only be just to flip outward to tilt naturally with outer edge 72, the edge sealing on both sides tilts so not only influences beauty very much, and And simultaneously because the Wave crest and wave trough that folding part described above is formed when pulling open feature, the edge sealing tilted in this way is obvious The both sides of mask body cannot be sealed well, it is clear that the air-tightness that mask both sides will be greatly reduced, to cause to leak Gas can thus greatly affected the filter effect of mask.Obviously this be also such disposable breathing mask design and molding Structure feature caused by inevitable phenomenon.

For this defect, by validation trial, the utility model proposes the solutions of segmentation bevel edge, such as scheme 10-17 show the solution of a variety of segmentation bevel edges, that is, the segmentation that unit design pressing is independent with each fold portion is sealed Sideline item, preferably edge sealing lines shown in legend orientation combination, including but not limited to these diagram in scheme, Because the disposable breathing mask is bilateral symmetry, few examples do not influence the exhibition of associated exemplary only with left-hand component Show.

The edge sealing lines are made of point or line segment, and point can be the point of arbitrary shape, and the size of point is flat with traditional mask 1 The point of square millimeter or so is advisable, and is no more than 3 square millimeters as possible, mask D2 as shown in figure 12 is the straight line bevel edge line of dot composition Item 93, other legends are square dot lines；The segmentation edge sealing lines are on one side at least oblique line, and oblique line side can be straight line, Can also be the bevel edge 92 that mask A10 as shown in figure 11 is slightly camber line, effect is identical, it can be understood as it is straight line, His legend is straight line；It can also be two or more bevel edge lines, such as Figure 17 that the segmentation edge sealing lines, which can be one, Shown mask C12 is the bevel edge lines 94 of two oblique lines composition, and for convenience of description, other legends are a line, the point of a line It is big a little to have good effect, preferably two oblique lines；The segmentation edge sealing lines can be one or two straight lines or arc Line can also be the edge sealing of triangle or gore that mask C13 as shown in figure 16 is made of point or face, the wherein nose of C13 Beam folding 11 is gore edge sealing lines 95, and folding part 21 is triangle edge sealing lines 96, and folding part 22 is sealed for right angled triangle Sideline item 97, folding part 23 are dotted face triangle edge sealing lines 98, as long as it is oblique line to keep a side, can substantially be expired Foot or part meet the utility model proposes segmentation bevel edge function；The segmentation edge sealing lines can be each fold portion Oblique line edge sealing is all used, can also be that partially folded portion uses, the bridge of the nose folding 11 of mask A10 as shown in figure 11 is traditional rectangular dot matrix Edge sealing preferably all uses oblique line edge sealing scheme, the bridge of the nose of mask D1 preferably as shown in Figure 10 to roll over 11 oblique line directions, There is optimum efficiency in such direction to the bridge of the nose and middle face domain 113.

In conclusion it is bevel edge or oblique line that above-mentioned edge sealing lines or face, which are substantially all there are one side or line, it is characterised in that Be non-perpendicular state with the fold line of the folding part under non-deployed condition, you can reach the utility model proposes segmentation bevel edge All or part of function be segmentation bevel edge by its Uniform Name, number in the accompanying drawings and be with 9 beginning labels for convenience of description 91,92,93......, the segmentation bevel edge of specification hereinafter can uniformly understand and be named as segmentation bevel edge 91.

Although only whole strip rectangle edge sealing of traditional disposable breathing mask is designed as described in the utility model Segmentation bevel edge 91, slight change can effectively improve the edge sealing gas leakage alice of above-mentioned traditional disposable breathing mask Phenomenon so that the edge sealing on mask both sides effectively improves the air-tightness on mask both sides closer to cheek, improves filtering effect Rate.

As shown in figure 9, Fig. 9 is the right enlarged drawing of the wearing effect figure of the utility model example mask D1 shown in Fig. 7, this Wearing effect figure in all attached drawings illustrated is all the photo imitation lines figure for wearing mask in kind, when the mask is upper and lower It pulls open when be worn on face, the edge sealing of the mask is under the pulling force effect of ear band 5, along the active force range line of edge sealing That is double directions arc dotted line L3 natural torsion camber shown in Fig. 9, the envelope of this present position L3 and traditional mask B1 in Fig. 8 Interior 71 position of edge sealing lines on side is suitable, and L4 is suitable with the position of outer sealing edge lines 72 of the edge sealing of B1, due to the mask D1 Each folding part all use it is described in the utility model segmentation bevel edge 91 design so that each fold portion is in edge sealing range Interior fold line can open certain angle that crosses one another, for example, in Fig. 9 folding part 21 two fold lines 212 and 211 And it is equivalent to there are one the angle intersected is substantially misaligned between two fold lines 222 and 221 of folding part 22 and has widened institute State the arc length of the edge sealing inner edge of mask D1, while each folding part can also be naturally at L4 at the outer edge of edge sealing An overlapping part, is equivalent to the length for reducing outer edge so that entire edge sealing, without tilting, but is fitted at fan shape On cheek, the air-tightness on mask both sides is effectively improved, improves the filter effect of mask, at will also mask is made to have on more Add beauty.

The edge sealing design sketch on the both sides of traditional disposable breathing mask B1 shown in comparison diagram 8, so that it may to find out, due to being typically all The dotted lines ultrasonic fusing of 2-4 items of use forms, edge sealing whole partially hard, the inner edge lines 71 of the mask edge sealing and outside The length of lines 72 is fixed from telescopic variation, and the fold line of folding part is all to be fixed in edge sealing parallel to each other always, Such as the fold line 222 and 221 of the folding part 22 in figure is substantially parallel in edge sealing, it is clear that can not be as the utility model The variation that the segmentation bevel edge 91 provided can make the fold line of each folding part generate certain intersecting angle, when inner edge lines 71 when bend to camber line, and outside lines 72 can only can necessarily flip outward, it is important to when such hard edge sealing bending The edge sealing can be made to become like arch bridge and equally arch upward, when the pulling force of ear band is inadequate, be not enough to move to its edge sealing touching cheek When, because the reason of the Wave crest and wave trough of its folding part generation, gas leakage is inevitable at the inner edge lines 71 to arch upward, especially small The user of shape of face wears the mask of 95mm wide, and mask alice on both sides rise and are not bonded, it is seen that it is several much to wear such mask It is almost to lose the filtering function to wear masks just as ornaments.

So the solution for the segmentation bevel edge 91 that the utility model innovatively proposes, and entirety are reduced to 85mm wide Disposable breathing mask described in the utility model can completely effectively solve the problems, such as this, and can better adapt to big absolutely Most crowds, preferably protect the public.

In addition the superimposing thread rolled over of each folding part is because without the traditional disposable breathing mask of picture to institute at edge sealing inner edge 71 Stating the superimposing thread rolled over of folding part, there are one the active forces for bonding drop-down so that under the segmentation bevel edge scheme that the utility model uses The superimposing thread rolled over of each folding part is able to discharge 3mm or so height outward so that mask cavity can farther away from lip position, It is less susceptible to be close to lip and a beneficial improvement compared to traditional disposable breathing mask.

In summary solution, the utility model proposes more optimized example, mask D1 as shown in Figure 7, mask D1 For the edge sealing of each folding part on both sides all using segmentation bevel edge 91, the folding direction D11 as shown in Figure 6 of each folding part is mouth It is continuous same folding that the folding schematic diagram for covering D1, which with exemplary disposable breathing mask C1 described in the utility model is several folding parts, Unlike folded direction, the exemplary disposable breathing mask D1 of the utility model second and third, four folding parts and the first folding part bridge of the nose The folding direction of folding 11 is exactly the opposite, and the folding schematic diagram C11 of mask C1 can be seen that difference, tradition are disposable in comparison diagram 6 The folding direction of the folding part of mask is folded to the same direction, design of the utility model based on bridge of the nose folding 11, unusual The innovation for being made that rule bridge of the nose folding 11 and folding the folding part negative direction among traditional disposable breathing mask, with bridge of the nose folding 11 Folding direction is on the contrary, internal folding wire 112 is opposite and adjacent with the internal folding wire 212 of folding part 21, when mask is unfolded, just Produce more beneficial effect.

The design sketch of mask D1 shown in wearing as shown in Figure 7, the beneficial effect generated in this way are exactly bridge of the nose folding 11 Superimposing thread rolled over 111 and folding part 21 superimposing thread rolled over 211 always in same flat cambered surface so that front domain 113 bends to flat Cambered surface, rather than as before mask C1 domain 113 be the curved surface of arc, more efficiently increase the mask at front domain 113 Cavity volume so that the filter area in the middle face domain 214 of front domain 113 and folding part 21 obtains maximum performance, compares mask The effective filtration area of C1 has certain promotion again.

Be exactly there are one beneficial effect, when mask D1 is unfolded, the supporting surface of bridge of the nose folding 11 i.e. in face domain 114 with The supporting surface of folding part 21 i.e. in face domain 214 as arch bridge, supported front domain 113 into flat cambered surface to intermediate resultant force, So that the even forced suction of front domain 113 is not easy to collapse and be attached to upper lip, effect is very good, oblique in conjunction with the segmentation Side 91, before domain 113 mask both sides complete docile in cheek, tightness is very good, this is also tradition one described above The thirdly indeterminable drawback of secondary property mask, such innovative design are to be worth affirmative, and can be rolled over by adjusting The width in folded portion 21 makes the support range in middle face domain 214 wider so that front domain 113 is wider, but no more than 20mm.Attached drawing In the example of all D words number be all to use such method for folding.

Yes, although being all the change of little bit, and it is very simple, any cost need not be increased, do not increased In the case of any process, a slight folding part is simply increased, is only the stripe shape for changing mask edge sealing, It just easily solves the worry of puzzlement in the industry so for many years, the defencive function of this mask is greatly improved, for same The very simple pocket-handkerchief of sample, actually small change, great change.

But this can be solved the problems, such as by not being one folding part of arbitrary increase, simple pocket-handkerchief, is transformed Get up and be just more difficult to, so so for many years, having lofty ideals for changing the innovators of this problem, none is not intended to increase on this It is desired to achieve the effect that add whatsit, however for such simple pocket-handkerchief, all because operability is not high, Cost performance is too poor and rarely has implementer, and the utility model is only to increase a folding, implements very simple, also Unexpected effect can be reached.

Although only only increase a slight folding, the present inventor is also for changing the two gas leakage The problem of problem and anti-breath, is worried for many years.Because general people even expects this mask increasing a folding Part also can be to increase a folding part the centre according to inertial thinking more, as B12 show intermediate 4 folding parts in Fig. 5 21,22,23,24, the integral position of this 4 folding parts is still either partial to middle section intermediate, and common people are substantially not Can as the utility model anti-convention design, fold directly discounting next to the position of nose bridge batten by one because Just have a property mask of the pure paper matter for food service industry of 4 foldings on the market, folded portion be exactly in intermediate position, Equally, for traditional disposable non-woven lint face mask, 3 folding, 4 folding even 5 foldings are made all without what too big difference in centre Not.

It is not only to have beaten a folding, it is important that beat this folding part thus it is possible to reach such effect more Position.

Obviously, such effect can be reached, be because the bridge of the nose folding 11 among middle face domain 114 play it is vital Effect, as shown in fig. 7, be because the bridge of the nose folding 11 middle face domain 114 at the wing of nose 41 of nasal fossa 4 substantially with the front domain 113 With the back domain 115 all in sty even vertical plane state, the support force in middle face domain 114 makes fold line 112 certainly Right ground docile has arrived in paranasal ala sulcus, the effect that the hot gas of blocking exhalation is scurried out has been functioned well as, therefore, when mask is unfolded It waits, i.e. at least more than half part, especially fold line 112 should be in the bridge of the noses for the main part in the middle face domain 114 of bridge of the nose folding 11 Locate position shown in L1 to L2, i.e. double straight positions dotted line L1, L2 shown in nose 81 to the bridge of the nose 82 in Fig. 7, such bridge of the nose folding 11 is just The advantageous effect that blocking hot gas is scurried out can be played.

The clear benefit and reason that this bridge of the nose folding 11 is beaten in bridge of the nose position is explained in detail if not with above-mentioned word, Others may be thought as the substandard products that the appearance of folded portion sideslip is caused because of equipment fault to the product worked it out, because of this nose Inherently a kind of achievement of anti-convention thinking of setting of beam folding 11, just as guessing riddles, only having spoken up can be bright White profoundness therein.

Similar example, there is a kind of disjunctor throwaway chopsticks, and traditional this throwaway chopsticks are all two once breaking into two with one's hands It is a pair of chopsticks, groove and the chopsticks seam of chopsticks connector are on one wire, to be conveniently divided into two, but this chopsticks connect The groove of head is perpendicular to chopsticks seam, a folding one dividing into three, and chopstick head can just be used as chopsticks pad, this intention is very Good, only the groove to fracture, which is had rotated 90 degree, just unexpected benefit, this intention has the utility model Prodigious enlightenment effect.

So big length is spent, only to illustrate, although the utility model only increases a slight folding, still It gives a discount in different positions, how to beat this folding, practical significance is to be very different.Although only changing mouth The stripe shape in cover edge sealing sideline, but be not each shape be all effective.With simplest method, minimum cost is complete It is the real meaning of invention at same target, so, the utility model is worth obtaining this patent power.
