Detailed Description

The glasses fogging prevention shield 1 of the present patent application, as shown in fig. 3, comprises a lining layer 112, an inner layer 113 inside the lining layer 112 and a surface layer 111 outside the lining layer 112, which are compounded together and cut according to the face width, wherein the length range of the downward covering extension of the upper edge 10 of the shield 1 should exceed the length of the bridge of the nose, and the length thereof preferably exceeds the mouth.

The inner liner layer 112 is made of hard liner type non-woven liner fabric with moderate hardness, specifically, non-woven liner with the weight of 60-100 g, paper liner, hot melt adhesive liner and the like can be selected, and the inner liner layer has good deformation resistance and support shape after being cut in a three-dimensional manner.

The upper edge 10 of the shield 1 is in sealing fit with the face 2, and the lower part of the shield 1 is supported by the high points of the face, such as the bridge of the nose and cheekbones, due to the stiff and smooth structure of the inner liner 112 and the wearing of the shield, so that the lower part of the shield 1 is separated from the mask body, i.e. the mask 8, and forms a communicated gap with the outside, as shown in fig. 2, wherein the gap is generally 1-2 cm. Breathe hot vapour and be blockked by anti-fogging separation blade 2 to by the guide of anti-fogging separation blade 2, discharge from the downside space 4 of keeping away from glasses, make glasses no longer receive breathing hot vapour and invade, thereby reach glasses and prevent the result of use of hazing.

The surface layer 111 is mainly a decorative fabric layer, and fabrics with different thickness textures, such as plush fabrics suitable for winter, can be selected according to different use seasons.

The inner layer 113 can be made of light thin cotton or thin smooth fabric, or a silver ion antibacterial fabric layer is selected, or a silver ion antibacterial fabric layer 114 is attached to the outer surface of the inner layer 113, so that bacterial growth on the mask in the shield cover or in combination with the mask can be effectively inhibited.

The upper edge of the baffle cover 1 is fixed with a plastic sealing strip for assisting the attaching of the human face 2, such as a sealing metal strip.

The blocking cover 1 is manufactured by three-dimensional cutting. As shown in fig. 1, the blocking cover 1 is formed by stitching a left symmetrical blocking piece 11 and a right symmetrical blocking piece 12 through a central line, the stitched central line 14 is an arc line along the bridge of the nose, the upper edges 10 of the two symmetrical blocking pieces 11 and 12 are upward along the side direction of the bridge of the nose to a protrusion 13 which is in a central arc shape and is arranged at the top end of the stitched central line 14, and the protrusion 13 and the upper edges 10 cover the bridge of the nose and are attached to the face of a person; the rear ends of the upper edges of the two symmetrical blocking pieces 11 and 12 preferably extend to the root of the ear, and the lower edges of the two symmetrical blocking pieces 11 and 12 are connected in a convex tip mode towards the bottom end of the stitching center line 14.

For the convenience of single use, the two sides of the shield 1 are provided with tying belts 3.

Fig. 4 shows an embodiment of the mask used in combination with a mask. The upper edge 10 of the shield 1 is flexibly connected with a sealing strip 4 for internally buckling the upper edge of the suspended respirator 8, as shown in fig. 5, and the shield 1 is combined with the respirator 8 through the sealing strip 4. The interior of the sealing strip 4 is fixed with a plastic sealing strip 5 for fitting the face of a person, such as a sealing metal strip.

The central line 6 of the sealing strip 4 is a concave arc line along with the nose shape relative to the central line 14 of the blocking cover, when the sealing strip 4 is turned over and internally buckled on the upper edge of the mask 8, the central line 6 of the sealing strip 4 is turned over and is basically matched with the inner and outer arc of the central line 14, and the sealing strip can be attached to the face of a person, particularly the nose bridge more comfortably.
