Description

A kind of slim mask breather valve

Technical field

This utility model is related to a kind of mask breather valve, especially a kind of slim mask breather valve.

Background technology

There are many mask with breather valve on the market, these breather valves are typically all relatively thicker list in sold mask Diaphragm breather valve, thickness typically in 11-14mm, what only a few was the thinnest also only accomplished 10mm about thick, typically tradition is exhaled The effective closing area inhaling the diaphragm of valve is 450-700mm, and the integral thickness of breather valve is partially thick, in the mouth of some styles Some positions of cover or existing breather valve mask are not very suitable for using.

The thickness of traditional breather valve is not also subject matter under existing use scene it is important that most mask Breather valve actually do not play corresponding using effect, is exactly at all much just as ornaments, for this universal phenomenon, The present inventor has formerly had been filed on Application No. 2016202159854《A kind of many valves piece mask breather valve》Utility model Application, the functional defect for existing mask breather valve is it is proposed that the very simple and practical beneficial of many valves diaphragm changes Enter although this utility model is greatly improved in terms of venting quality, but the overall appearance design of breather valve still with biography System mask breather valve ratio is relatively similar, is also the abundant design of comparison, major part is still also used in clamshell folding mouth mask Lip near sites.

Because this kind of breather valve is all thicker, therefore fold on non-woven fabrics gauze mask just less such as slim disposable three It is suitable for using, so the three folding disposable non-woven lint face masks not carrying breather valve on the market are sold.

Utility model content

For traditional mask breather valve all too thick using limitation, in conjunction with many valves diaphragm of the present inventor's earlier application Intention, the utility model proposes breather valve base portion especially has carried out the design of more optimization by mask breather valve, with Ask and reach less, thinner design and use effect, make it possible to use on more different types of masks, or use Be inconvenient to other the more positions of mask using in some tradition breather valve masks.

The utility model proposes a kind of mask breather valve, especially a kind of slim mask breather valve it is characterised in that：Institute State the breather valve film lobe seat that slim breather valve has one or more multiple film lobes, described film lobe seat is to have different shape aerofluxuss Hole and the independent miniature film lobe seat separating film lobe, described slim breather valve has the breather valve valve gap corresponding to film lobe seat.

, it is desirable to the radius of turn opened of diaphragm is as little as possible, diaphragm opens for mentality of designing based on thinner breather valve Torque ratio requirement is more rationally more practical, and this utility model is by the area coverage of single for breather valve diaphragm in the valve outlet hole that ensures respiration It is optimized design on the basis of unobstructed optimum using effect, make every effort to the using effect that optimization diaphragm is opened or closed, such as Fig. 1 show diaphragm 01 splaying effect schematic diagram, and in figure show the film lobe 011 of described diaphragm 01 with rotary shaft 012 for axially The state opened, the area of effective coverage S of described film lobe 011 and length L of rotary shaft 012 square ratio be torque ratio extremely It is greater than 1 just relatively more reasonable, i.e. S ÷ L ＞ 1 less, the effect that so gas of exhalation is discharged just can be accordingly quite a lot of, and this practicality is new Type recommends preferred torque ratio to be more than 1.5 about, and so gas of exhalation will be more lighter when discharging.

Carry out corresponding intention optimization based on the torque ratio formula that this utility model will be extracted based on this, ensureing Good exhale discharge effect on the premise of be designed to be as small as possible in the hope of breather valve, thin for principle.

As shown in Figure 2 the preferred length of rectangle steam vent 13 of breathing valve base 10 is 7mm, and width is 4mm, The length and width of the corresponding film lobe 011 using about 7.8mmX5.6mm about, torque ratio is about 1.4, substantially conforms to this utility model institute State the torque ratio concept requirement of diaphragm.

Based on thinner mentality of designing, in conjunction with described torque ratio concept, this utility model also needs to carry out breathing valve base More thinning design, is illustrated in figure 2 the most basic many valves of this utility model six rectangle steam vent combination types breathing valve base 10, the in figure breathing preferably long 5-10mm of valve outlet hole 13 about, wide 3-7mm about, covered than traditional breather valve monolithic diaphragm Ventilation aperture area much smaller, more preferably grow a width of 7mmX4mm, the thickness of the base plate 101 of described breathing valve base 10 Degree can accomplish 0.1-1mm, preferably 0.2-0.5mm, the thickness of base plate 101 of in figure valve seat 10 and example below The base plate thickness of base described in two is designed as 0.2mm, and in figure rectangle steam vent 13 peripheral part exceeds base plate 101, constitutes Film lobe seat 112, the thickness exceeding is designed as 0.1-1mm, preferably 0.3-0.6mm about, it is left that this in figure is designed as 0.3mm Right.So, the thickness of whole breathing valve base 10 can accomplish 0.5mm.

Because entirely the design thickness of breathing valve base 10 can accomplish only very thin 0.5mm, if described exhale Inhaling valve is design and installation it may happen that bending under the use scene at the position of bending, such as example below two, in use Power may be such that very thin film lobe seat itself produces deformation, thus lead to diaphragm sealing state change cause possible Gas leakage, is designed between film lobe seat 112 two-by-two as shown in Figure 2 and unloads power groove 16, the described lobe seat of film two-by-two less than film lobe seat Between have can unload power groove design, so when occur bending situation when, bending section branch produces naturally in base 10 Position the weakest, that is, unload at power groove 16, such design can dissolve breathing valve base under thinner design requirement The deformation ratio of film lobe seat can also be ensured as much as possible.

Unloading power groove 16 described in Fig. 2 is right-angle side groove, of course it is also possible to will unload the design of power groove as shown in Figure 3 It is arc or triangle unloads power groove 161, simultaneously can also correspondence position design in the middle of the back side two film lobe seat of base plate 101 Similar unloads power groove 162, can act as unloading the effect of bending power, anchor point adopts location hole 141 design.

Of course, if the thickness of breathing valve base design is more than 1mm, or the position that design uses will not produce During big bending, described valve seat has enough hardness to resist smaller deformation power produced by general mask it is possible to need not The groove of power is unloaded in design, as shown in figure 4, film lobe seat can be designed to the full wafer shape of imposite film lobe seat 111.

Fig. 5 show the rectangle six valve diaphragm 010 corresponding to breathing valve base 10 Aided design shown in Fig. 3, adopts Injection gel silica membrane, because the diaphragm of the relatively conventional breather valve of film lobe of described diaphragm is little a lot, therefore this utility model is adopted The thickness of diaphragm is also thinner than the diaphragm of traditional breather valve 0.4mm left and right thickness a lot, only needs 0.2mm, in figure diaphragm Positioning table 163 is corresponding with unloading power groove 160 in Fig. 3, plays certain fixation, in figure papillary bulge 142 and positioning Hole 141 corresponding matching, acts the effect installing positioning, and certain diaphragm can also adopt cutting die punching molding, such as corresponds to Fig. 4 institute The diaphragm of the breathing valve base of the justifying film lobe seat 111 showing, if the anchor point of described valve seat is designed as the positioning shown in figure 2 Post 14, then the anchor point of corresponding diaphragm be designed to corresponding location hole of course.

It is possible to further the design of more optimization is done on the film lobe seat of described breathing valve base, as shown in fig. 6, in institute State the steam vent 13 of film lobe seat three sides design a wide 0.5mm about domatic stalk 12, constitute the film lobe seat 113 of diagram, Described domatic stalk two corresponding sides are triangular in shape with the upper surface of described film lobe seat 113 for plane for described domatic stalk 12 domatic, and two The highest point 1-3mm of contained side in the middle of corresponding sides about, preferably 1.5mm about, described film lobe seat tool has around different shape row The domatic stalk of the domatic of pore edge setting, the described domatic stalk high 1-3mm of highest point, described domatic obstructs 12 so that diaphragm Film lobe 011 keeps the stress of a closing adhesive with respect to breathing valve base, is also prevented from too thin diaphragm simultaneously and is pasted onto Thus affecting exhaust effect on the smooth upper surface of film lobe seat.In addition because diaphragm is very thin very soft, it is punched by cutting die and produces Gap very little, described domatic stalk it is also possible that by the film lobe of diaphragm of cutting die punching molding with ride over the upper of film lobe seat Between the diaphragm on surface formed a difference in height, prevent film lobe because possible skew so that in adhesive film lobe be shelved on diaphragm On, affect sealing effectiveness.

It should be evident that domatic stalk can also be designed to flat cambered surface 121 as shown in Figure 7, constitute the film lobe seat of diagram 114, it is also possible to described domatic stalk is designed to the domatic stalk 122 of arch cambered surface as shown in Figure 8, constitute the film lobe seat 115 of diagram, Because the width of described domatic stalk only has the 0.5mm of very little, its surface configuration is not overly critical, the height of domatic extension Degree difference is more relatively important.
