As a further solution of the present utility model, the ear strap is made of a pure cotton flat elastic band with a width of 2.0cm-3.5cm, and the end of the ear strap and the junction of the mask body are hot-pressed and fixed with a reinforcing sheet .

The beneficial effects of the utility model are:

1. This mask is based on the traditional mask, and the window is opened in the breathing part of the human body. The nose part uses the nose chamber to discharge the gas through the nostril end, reducing the water vapor entering the lens through the sides of the nose and reducing the accumulation of fog. At the same time, the mouth uses Fitted air-permeable cloth ensures good air permeability and reduces the accumulation of fog to the nose;

2. This mask is equipped with shaping strips and color-changing nose pads on the nose. The shaping strips are used to fix the nose, and the color-changing nose pads are used to detect whether the mask body is wet. Using the principle of aluminum chloride changing color when it meets water, it prompts to replace the mask in time;

3. The four-layer cloth structure of the mask is composite, the activated carbon absorbs the odor of the exit gas, and the melt-blown cloth blocks most of the germs, and the water-absorbing cloth layer and the protective cloth are used for the internal and external protection of the mask to improve the safety of the mask protection.

Detailed ways

The technical solution in the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the utility model. Obviously, what is described is only a part of the utility model, not the whole.

Referring to Figures 1-4, an anti-fogging protective mask includes a mask body 1, the four sides of the mask body 1 are seamed with edge banding 3, and the inner wall of the bottom end of the edge banding 3 is interspersed with a lower jaw laminating elastic band 6, The outer walls on both sides of the mask body 1 are symmetrically fixedly connected with semi-circular ear straps 2, the middle part of the top outer wall of the mask body 1 is provided with a nose compartment 4, and the top outer wall of the nose compartment 4 is snapped with a fixed piece 5, the mask body 1 The middle part of the inner wall is located at the bottom of the nose compartment 4, and the mouth breathable cloth 7 is provided. The nose compartment 4 is a triangular prism structure, and the inner wall of the bottom end of the nose compartment 4 and the inner edge of the mouth breathable cloth 7 are provided with breathable melt-blown cloth. , the middle part of the inner wall of the fixed piece 5 is interspersed with an aluminum custom-shaped strip 8, and the middle part of the inner edge of the fixed piece 5 is fixedly connected with a color-changing nose pad 9, which is arc-shaped and fits on the bridge of the nose, and the color-changing nose The interior of the pad 9 is hollow and filled with aluminum chloride material, and the inner wall of the bottom end of the color-changing nose pad 9 is provided with air holes communicating with the aluminum chloride material.

The mask body 1 includes an outer protective cloth 11, an activated carbon layer 12, a melt-blown cloth layer 13 and a water-absorbent cloth layer 14. The activated carbon layer 12 and the melt-blown cloth layer 13 are located between the outer protective cloth 11 and the water-absorbent cloth layer 14. The outer protective cloth 11 It is composed of 50% pure cotton, 40% polyester fiber and 5% polyester fiber. The absorbent cloth layer 14 is composed of 95% pure cotton and 5% polyester fiber.
