However, adjusting the radian of the nursing mask by means of the straps necessarily requires the straps to apply a certain binding force, and a larger binding force can increase the pressure of the whole fitting face of the nursing mask, thereby causing the problem of uncomfortable wearing.
As shown in fig. 1, in order to solve the above technical problems, the present embodiment provides a mask radian adjustment device, which includes an elastic mask body, wherein the elastic mask body includes a mask attaching rear shell 10, a lamp bead arrangement layer 20 and an opaque front shell 30, which are sequentially arranged from inside to outside;
the opaque front shell 30 is an opaque first elastic shell, at least one group of spoke lamp bead groups are arranged on the lamp bead arrangement layer 20, the lamp bead arrangement layer 20 is a flexible layer, the mask attaching rear shell 10 is a second elastic shell, and the mask attaching rear shell 10, the lamp bead arrangement layer 20 and the opaque front shell 30 are integrally and fixedly connected;
the mask attaching rear shell 10 is provided with an adjusting air bag 40 for adjusting the bending radian of the elastic mask body, and the adjusting air bag 40 is transversely arranged on the mask attaching rear shell 10 in a strip shape.
The regulating air bag 40 is connected with an air charging and discharging main machine through an air tap, and the air charging and discharging main machine is arranged on the mask controller. The air bag 40 is inflated or deflated through the inflation and deflation main machine, the connecting hose and the air tap, and then the transverse radian of the elastic mask body is adjusted. The air tap of the regulating air bag 40 is also provided with a control switch valve. The control switch valve may be an electromagnetic valve, and the inflation state of the airbag 40 is stably regulated by closing the electromagnetic valve, so that the elastic mask body stably maintains a certain radian.

When the hardness of the first elastic shell is equal to that of the second elastic shell, the bending variable of the mask-fitted rear shell 10 and the bending variable of the opaque front shell 30 are substantially the same, when the hardness of the first elastic shell is greater than that of the second elastic shell, the bending variable of the opaque front shell 30 is smaller than that of the mask-fitted rear shell 10, and when the hardness of the first elastic shell is smaller than that of the second elastic shell, the bending variable of the opaque front shell 30 is greater than that of the mask-fitted rear shell 10. The hardness of the first elastic shell and the second elastic shell can be selected according to different use scenes.
In another embodiment, the adjusting air bag 40 is disposed on the face-facing side of the mask-attaching rear shell 10, as shown in fig. 3, the adjusting air bag 40 is disposed on the innermost layer of the elastic mask body, and in the inflated and deflated state of the adjusting air bag 40, although the original mask-attaching rear shell 10, the light bead arrangement layer 20 and the opaque front shell 30 will not be deformed greatly, the gap between the elastic mask body and the face is filled or released due to the deformation of the air bag, and finally the radian adjustment of the mask can be realized.
Specifically, the adjusting airbag 40 is further provided with a flexible cushion on the side facing the face to increase the softness of the nursing mask for facial fitting.
The adjusting air bag 40 is arranged on the mask attaching rear shell 10 at the inner side of the elastic mask main body of the multiple layers, and the bending radian of the mask attaching rear shell 10 is adjusted by filling gas into the adjusting air bag 40 or discharging gas, so that the bending radian of the nursing mask is finally realized. The bending radian of the nursing mask is adjusted by adjusting the inflation and deflation of the air bag 40, the binding force of binding can not be increased, and therefore the increase of the extrusion force to the face caused by the change of the radian of the elastic mask main body can be avoided, and the fitting degree and the comfort degree of wearing the mask can be effectively improved.
The embodiment also provides a nursing mask, which comprises a mask radian adjusting device, wherein the mask radian adjusting device comprises an elastic mask body, and the elastic mask body comprises a mask attaching rear shell 10, a lamp bead arrangement layer 20 and an opaque front shell 30 which are sequentially arranged from inside to outside; the opaque front shell 30 is an opaque first elastic shell, at least one group of spoke lamp bead groups are arranged on the lamp bead arrangement layer 20, the lamp bead arrangement layer 20 is a flexible layer, the mask attaching rear shell 10 is a second elastic shell, and the mask attaching rear shell 10, the lamp bead arrangement layer 20 and the opaque front shell 30 are integrally and fixedly connected; the mask attaching rear shell 10 is provided with an adjusting air bag 40 for adjusting the bending radian of the elastic mask body, and the adjusting air bag 40 is transversely arranged on the mask attaching rear shell 10 in a strip shape.
