Abstract:
A mask having an LV structure and a device thereof. A V-shaped structure is fixed on the upper portion of a mask body (9), i.e., a half of the V-shaped structure is provided at the upper portion of each edge of the mask body, the V-shaped structure is arranged downwards from the corner of each edge and towards the left and right middle lines of the mask, and the left and right corners of the upper portion of the mask are slidably connected to the V-shaped structure; and the V-shaped structure is located at the left and right end portions of the two corners of the mask, so that the V-shaped structure can be extended or fixed on the face or head of a person by means of a connecting component. In dozens of years, the structure of the mask is changed into two parts from original three parts, and the mask serves as a medical mask and a protective mask, and thus greatly promotes the effects of energy saving, environmental protection, and small innovation. The structure of the mask body (9) is not changed, and the mask body is suitable for large-scale production of an existing epidemic situation. An existing tableting machine can be used, so that the mask having three parts being replaced with two parts is truly realized on the basis of the existing industry. The device is very simple in structure and low in cost, and can quickly produce the mask.
