This utility model provides a kind of forehead protective pad, comprising fixed part 11, support portion and top.Support portion at least comprises the first support portion 121 and the second support portion 121, support portion 122, first have on the first top 1211 and the first support portion 122, bottom 1212, second and has the second top 1221 and the second bottom 1222.First bottom 1212 of the first support portion 121 is fixedly installed on fixed part 11, and accordingly, the second bottom 1222 of the second support portion 122 is also fixedly installed on fixed part 11.Especially, top is elastic top 13, when elastic top 13 is subject to stress, can produce the elastic deformation of stretching or shrinking.First top 1211 of the first support portion 121 is arranged in elastic top 13, and accordingly, the second top 1221 of the second support portion 122 is also arranged in elastic top 13.Relative distance between first bottom 1212 and the second bottom 1222 should be less than the relative distance between the first top 1211 and the second top 1221.Fixed part 11, support portion and elastic top 13 form a frame structure, and support portion forms certain space between elastic top 13 and fixed part 11.Forehead protective pad entirety can be made up of elasticity, deformable material, to reach reliable deformation effects.Preferably, the material of forehead protective pad can be silica gel or elastomeric material, the material such as silica gel and rubber can provide good elastic performance for forehead protective pad, and those skilled in the art by the thickness of adjustment fixed part, support portion and elastic top 13, can change the elastic performance between each portion.
When elastic top 13 and fixed part 11 are subject to the active force making both close to each other, due to two support portions bottom between distance be less than distance between two tops, so, support portion this active force can be divided send as an envoy to the first top 1211 and the second top 1221 mutually away from component.Under the effect of this component, elastic top 13 can produce extensional deformation, and the distance between the first top 1211 and the second top 1221 is increased.Distance between two tops increases, and makes two support portions produce or angle of inclination increase, thus reduces the distance between fixed part 11 and elastic top 13.When remove this make elastic top 13 and fixed part 11 active force close to each other time, elastic top 13 can produce contraction distortion, returns to initial shape.The top of two support portions is close to each other, reduces the angle of inclination of support portion, thus makes range recovery between fixed part 11 and elastic top 13 to original state.Pass through said process, forehead protective pad of the present utility model can adjust the relative distance between fixed part 11 and elastic top 13, the forehead supports 3 forehead protective pad being contained in Ventilation mask can realize automatically the adjustment of height, to adapt to the forehead height of different individual.
Concrete, as shown in Figure 1, elastic top 13 is undulate structure preferably, and corrugated elastic top better can produce and stretches or shrink deformation.Elastic top 13 is connected with fixed part 11 by support portion, and the distance between elastic top 13 and fixed part 11 is supported by two support portions and forms.Support portion is preferably gripper shoe, and the first support portion 121 is the first gripper shoe, and the second support portion 122 is the second gripper shoe.The support portion of platy structure better can provide support effect, also can be more stable be disperseed to both sides by pressure.The bearing of trend of the wavy shaped configuration of elastic top 13 should be identical with the incline direction of gripper shoe, when increasing to make the angle of inclination of gripper shoe, can order about elastic top smoothly and produce extensional deformation.Especially, when gripper shoe is dull and stereotyped, the first gripper shoe should be parallel with the intersection of fixed part 11 with the second gripper shoe with the intersection of fixed part 11, and two intersections relative to fixed part 11 center line axisymmetricly.Like this, the first gripper shoe and the second gripper shoe can tilt to two antipodal directions, by pressure to two contrary direction dispersions, better can order about elastic top 13 and produce extensional deformation.As shown in Figure 2, the distance between the first top 1211 and the second top 1221 is greater than the distance between the first bottom 1212 and the second bottom 1222.When elastic top 13 and bottom are subject to the pressure making the two close to each other, pressure can disperse to both sides by support portion, makes elastic top 13 produce extensional deformation, thus increases the angle of inclination of two support portions, makes elastic top 13 and bottom close to each other.Gripper shoe can also be the bent plate with radian, and gripper shoe has bending in the vertical, namely bending along the direction from fixed part to elastic top.Now the intersection of gripper shoe and fixed part is not straight line, and two intersections are usually not parallel, but the intersection of the first gripper shoe and fixed part still with the intersection of the second gripper shoe and fixed part relative to fixed part center line axisymmetricly, be conducive to the bulk deformation of forehead protective pad.In the embodiment shown in Fig. 1,2, in order to enable support portion be disperseed to both sides by pressure, when not being under pressure effect, the included angle A of support portion and fixed part 11 should be greater than 90 °.Certainly, this utility model does not limit included angle A must be greater than 90 °, and when included angle A equals 90 °, as long as the distance between two tops is greater than the distance between two bottoms, the function of being disperseed to both sides by pressure still can be played in support portion.
Except the specific embodiment shown in Fig. 1,2, the wavy shaped configuration of elastic top 13 can also be other forms, and such as, side is the structure of polyline shaped, or in being spread the wavy shaped configuration of extension towards periphery by center.Accordingly, support portion is not only a kind of form of gripper shoe yet, can also be the structures such as support bar.Fig. 1,2 embodiment in, forehead protective pad comprises the first support portion and the second support portion, but in other embodiments, forehead protective pad can also comprise more support portion.Such as, when elastic top is in when spreading the wavy shaped configuration of extension towards periphery by center, can arrange multiple bar-like support portion between elastic top and bottom, the top of multiple support portion distributes in the form of a ring in elastic top, can cross promotion elastic top and produce extensional deformation towards periphery.This utility model does not specifically limit above feature, and those skilled in the art according to practical situation, can design the structure of elastic top, support portion, the quantity of support portion.
Further, the inclined degree of support portion is larger, is easilier disperseed to both sides by pressure, but more weak to the supporting role between elastic top 13 and bottom; Contrary, when support portion is perpendicular to elastic top 13 and bottom, it can provide good supporting role to elastic top 13 and bottom, but is more difficultly disperseed to both sides by pressure.So, preferably, effectively the both sides of pressure to elastic top 13 can either be disperseed to make support portion, good supporting role can be provided again to elastic top 13 and bottom, that the included angle A between support portion and fixed part 11 should between 120 ° to 135 ° in elastic top 13 and the bottom effect of not being under pressure.
On the other hand, forehead protective pad is when being subject to suitable pressure effect, and elastic top 13 just should produce extensional deformation, so that the distance between adjustable elastic top 13 and bottom.If elastic top 13 is really up to the mark, even if then forehead protective pad is subject to larger pressure, elastic top 13 can only produce a small amount of distortion, and this situation can make the patient worn feel forehead discomfort.And if elastic top 13 is excessively soft, then, when forehead protective pad is subject to less pressure, elastic top 13 will produce moderate finite deformation, and this situation can make forehead protective pad can not provide reliable supporting role, cannot share the pressure of Ventilation mask main body to patient facial region.So in order to avoid above-mentioned two situations, the forehead protective pad making this utility model provide both had had suitable deformability, can provide reliable supporting role again, so the thickness of elastic top 13 is preferably between 1mm to 1.5mm.
Especially, in embodiment as shown in Figure 1, 2, the overall structure that fixed part 11, first support portion 121 and the second support portion 122 are formed in one, so, when the distance on the first top 1211 and the second top 1221 increases, the junction of support portion and fixed part 11 can be subject to stress and produce distortion, and included angle A is increased.This stress likely makes fixed part 11 self produce deformation, but fixed part 11, as the fixed installation position of forehead protective pad and forehead supports, should reduce deformation, loosening possibility as far as possible.So in order to the hardness that ensures fixed part 11 and rigidity, the thickness of fixed part 11 is preferably between 2.5mm to 3.5mm.
In addition, in embodiment as shown in Figure 1, 2, the preferred rectangular plate of structure of fixed part 11, first top 1211 of the first support portion 121 is fixedly connected on a lateral edges place of rectangle fixed part 11, and 1221, second top of the second support portion 122 is fixedly connected on another lateral edges place of the rectangle fixed part 11 relative with the first top 1211.First support portion 121 and the second support portion 122 can be supporting plate structure, and the intersection of support portion and fixed part 11 is the lateral edges of rectangle fixed part 11.Like this, not only structure is simple, and moulding process is simple, also can provide good deformation condition for forehead protective pad entirety.Usually, the thickness in plate-like support portion is evenly unified, but gripper shoe also can have different thickness in different positions.Such as, the bottom thickness in plate-like support portion can be less than the thickness of support portion other parts, and this design is more conducive to the adjustment of forehead protective pad height.
Further, this utility model additionally provides a kind of Ventilation mask, and as shown in Figure 3, Ventilation mask comprises mask body 2, forehead supports 3 and above-mentioned forehead protective pad.Wherein, the front end of forehead supports 3 is provided with bindiny mechanism 31, as shown in Figure 4, the fixed part 11 of forehead protective pad then has fixed mechanism 111, as shown in Figure 1.Forehead protective pad is assemblied on forehead supports 3 by fixed mechanism 111 and bindiny mechanism 31, and fixed mechanism 111 is fixedly connected with bindiny mechanism 31.Mask body 2 is provided with the lower headband hook for connecting lower headband, and the end of forehead supports 3 is provided with the upper headband hook for connecting upper headband, face shield can be fixed on face by upper and lower headband hook by user, and the good fit by regulating the degree of tightness of lower headband to realize face shield bottom and face.Equally, user by regulating the degree of tightness of upper headband, can also make forehead produce pressure to forehead protective pad, making elastic top 13 produce extensional deformation, reducing the distance between elastic top 13 and bottom 11, make mask cushion top be fitted in face better.
Preferably, fixed mechanism 111 can be installing hole, and bindiny mechanism 31 can be grab, and when forehead protective pad is arranged on forehead supports 3, snap fit snaps in installing hole, as shown in Figure 5.Snap fit can be stable be connected in installing hole, thus fixed part 11 to be stably fixed on forehead supports 3.This utility model is not specifically limited bindiny mechanism 31 and fixed mechanism 111 mechanism of assembling, and those skilled in the art can design fixed mechanism 111 and bindiny mechanism 31 according to practical situation.Such as, fixed mechanism 111 can be screwed hole, and bindiny mechanism 31 can be made up of through hole and screw association.
