[0026] As an embodiment of the application, support cloth 7 is fixedly connected to the inner wall of headgear body 1 close to installation port 3, and the support cloth 7 is made of inelastic fabric;When working, the stability of face shield 5 and headgear body 1 during working process is maintained by the set support cloth 7, and the air permeability of air vent 6 is maintained.

[0027] As an embodiment of the application, glasses port 8 is symmetrically provided on the left and right sides of headgear body 1, and the glasses port 8 is used for inserting the external glasses legs;When working, the glasses port 8 symmetrically provided on the two sides of headgear body 1 can effectively solve the problem that the glasses legs cannot be inserted into the headgear when wearing the headgear, thereby improving the comfort and stability of wearing.

[0028] By setting up the glasses port 8 on the left and right sides of the headgear body 1, the external glasses legs can be inserted therein, ensuring the stable wearing of glasses, while avoiding the interference between the headgear and the glasses. Compared with the prior art, this design of the present application improves the wearing comfort, solves the problem that the glasses legs cannot be inserted into the headgear when wearing the headgear, and has significant practical value.

[0029] As an embodiment of the present application, the sealing mechanism comprises a bracket 9 fixedly connected to the inner side of the mask 5, and a sealing element 10 in the shape of a nose bridge fixedly arranged on the side wall of the bracket 9; in operation, a bracket 9 is arranged on the inner side of the mask 5, and the bracket 9 is fixedly connected to the inner side of the mask 5 to ensure that the bracket 9 can be stably supported inside the mask 5, and a sealing element 10 is installed on the side wall of the bracket 9, which is fitted according to the shape of the nose bridge and can effectively form a seal with the nose bridge, thereby preventing hot air from rising into the mask 5 and reducing the formation of fog;

[0030] The sealing element 10 can be made of a soft and elastic material to ensure comfortable fitting of the nose bridge during wearing, avoiding discomfort caused by too hard or unsuitable materials for the nose bridge, and the sealing element 10 can be customized according to different nose bridge shapes to improve the sealing effect, in addition, the bracket 9 can be made of a lightweight and strong material to provide sufficient support without increasing the weight of the mask 5;

Compared with the prior art, the design of the present application improves the comfort and practicality of the headgear, especially in cold environments, which can better protect the user's face.

[0032] As an embodiment of the present application, the sealing element 10 is made of EVA foamed material; EVA foamed material has good elasticity and softness, which can effectively fit the facial contour, especially the nose bridge part, by using this material, it can ensure that the sealing element 10 will not cause discomfort to the skin during use, while providing good sealing effect, preventing hot steam from rising to the observation port 2 area, reducing the formation of fog.

[0033] Specifically, the EVA foaming material has the characteristics of light weight, softness, and strong plasticity. Its excellent elasticity and softness enable it to closely fit the shape of the nose bridge and form an effective seal, thereby effectively preventing the exhaled hot air of the user from entering the inside of the headgear, avoiding the fogging of the glasses or helmet lenses. At the same time, the poor air permeability of the EVA material helps to keep the sealed area dry, further reducing the accumulation of moisture.

[0034] As an embodiment of the present application, the headgear body 1 is made of a polar fleece fabric or a breathable thin fabric. The polar fleece fabric has good warmth retention performance and soft touch, and is suitable for use in cold environments. The breathable thin fabric can ensure good air permeability and is suitable for use in warm environments. The selection of the two fabrics provides flexibility to adapt to different environments, further improving the application range and comfort of the headgear.

[0035] The headgear body 1 of the present application can not only provide a comfortable wearing experience in different environments, but also effectively solve the problem of fogging inside the headgear in the prior art.

[0036] As an embodiment of the present application, the mounting port 3 is located below the observation port 2.

[0037] As an embodiment of the present application, the protective cover 501 is made of a supportive air-tight sponge fabric. Technical solution explanation: The anti-fog headgear of the present application forms a face mask 5 with a protrusion by opening an observation port 2 and a mounting port 3 on the front side of the headgear body 1, bonding an elastic edge 4 on the edge of the observation port 2, sewing a protective cover 501 at both ends of the elastic edge 4, forming a face mask 5 with a protrusion, forming an air vent 6 between the lower part of the face mask 5 and the inside of the headgear body 1 for the discharge of fog to reduce the formation of moisture, and providing a sealing mechanism on the upper side of the side close to the inside of the headgear body 1 for sealing between the nose bridge. The protective cover 501 is made of a supportive air-tight sponge fabric. This supportive air-tight sponge fabric has good support and air-tightness, which can effectively block the entry of external cold air and prevent the leakage of internal hot air. Specifically, the supportive air-tight sponge fabric can be made by high-density foaming process, which has good shape retention ability and heat insulation performance. As a preferred embodiment, a soft lining can be added to the inner layer of the protective cover 501 to improve the wearing comfort.

[0038] As an embodiment of the present application, the lower edge of the protective cover 501 is three-stitched near the secondary stitching position and the edge of the mounting port 3, the secondary stitching and the tertiary stitching are sequential and continuous, and the stitching length after the tertiary stitching is one fourth of the length of the lower edge of the protective cover 501; in operation, the secondary stitching and the tertiary stitching are sequential and continuous, which facilitates the connection of the protective cover 501 and the surface of the headgear body 1 at the edge of the mounting port 3, and the length of the tertiary stitching under the protective cover 501 is set to one fourth of the length of the lower edge of the protective cover 501, which improves the stability of the stitching connection and facilitates the formation of the convex of the face shield 5.

[0039] As an embodiment of the present application, the upper edge length of the protective cover 501 is greater than the lower edge length; the technical solution of this design mainly changes the shape of the protective cover 501, so that the protective cover 501 can better fit the face, especially the position of the nasal bridge and the cheekbone, thereby improving the sealing effect and reducing the formation of fog; the design of the upper edge length of the protective cover 501 being greater than the lower edge length facilitates the formation of the face shield 5 with a convex after stitching, which can make the face shield 5 more stable when worn and not easy to slide, and can also provide a larger coverage area and increase the warmth retention effect, in addition, this design can also make the protective cover 501 have a higher fit on the face and improve the comfort.

[0040] As a preferred embodiment, a layer of material with a certain hardness, such as a plastic strip or a metal wire, can be added to the upper edge of the protective cover 501 to maintain the shape and stability of the protective cover 501.

[0041] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application.
