The decompression pad 6 increases the stress area, not only can prevent the mask body 1 from slipping, but also can relieve discomfort, and avoids the injury and pressure injury caused by the pressure of the back of the head or the back of the ear.

Referring to fig. 1 to 5, in some embodiments of the present application, the first fixing band 2 and the second fixing band 3 may also use a lace without elasticity, instead of an elastic band. The first fixing band 2 and the second fixing band 3 are provided with adjusting pieces 7 for adjusting the tightness of the mask when the mask is worn.

Specifically, a notch 61 for exposing the first fixing strap 2 or the second fixing strap 3 is disposed on the outer side of the pressure reducing pad 6, and the adjusting member 7 is disposed on a portion of the first fixing strap 2 or the second fixing strap 3 exposed from the notch 61.

Referring to fig. 1 and 2, the adjusting member 7 may be a clip, and in use, the first fastening tape 2 or the second fastening tape 3 may be pulled out from the gap 61 of the pressure reducing pad 6 by a suitable length, and then the pulled out portion of the first fastening tape 2 or the second fastening tape 3 may be folded in half, and finally the clip may be clamped on the folded portion of the first fastening tape 2 or the second fastening tape 3 outside the gap 61.

Referring to fig. 1 and 2, the adjusting member 7 may be a hook and loop fastener. The magic tape comprises a magic tape rough surface and a magic tape hook surface. The magic tape hair side with the hook surface is pasted to the magic, and the interval sets up first fixed band 2 or on the 3 inner faces of second fixed band. When the fixing device is used, the first fixing band 2 or the second fixing band 3 can be pulled out of the gap 61 on the pressure reducing pad 6 by a proper length, then the first fixing band 2 or the second fixing band 3 is partially pulled out and folded, and at the moment, the hook-and-loop fastener is adhered to the hook-and-loop fastener.

Referring to fig. 1 and 2, the adjustment member 7 may be a snap fastener. The snap fastener comprises a plurality of female fasteners and a group of male fasteners. A plurality of box and a set of pin thread, the interval sets up first fixed band 2 or on the 3 inner faces of second fixed band. When in use, the first fixing strap 2 or the second fixing strap 3 can be drawn out from the gap 61 on the pressure reducing pad 6 for a proper length, and then the drawn part of the first fixing strap 2 or the second fixing strap 3 is folded in half, and at this time, any female buckle is matched with the male buckle.

Referring to fig. 1 and 3, the adjusting member 7 may be a buckle.

Referring to fig. 1, the mask body 1 is provided with a breather valve 8, and the elastic pad 5 is made of one of sponge, hydrogel, memory cotton and silica gel.
