Technical Field

[0001] This utility model belongs to the technical field of face mask equipment, specifically relating to a high-efficiency protective gas mask for nuclear radiation environments. Background Technology

[0002] Nuclear science and technology have been widely applied in various fields such as national defense, energy, industry, and medicine, bringing enormous economic and social benefits. However, they have also increased people's exposure to various forms of radiation and their potential threats, making nuclear and radiation safety issues increasingly prominent and attracting widespread attention. Radiation protection materials and equipment are crucial for ensuring the safety of workers and the public in radiation-affected areas, and are an effective means of mitigating nuclear accident crises. They are also an important guarantee for military and civilian radiation safety protection and are in urgent need.

[0003] In the medical field, radiation protection masks are required to avoid radiation damage to the face and eyes. However, most existing masks come into direct contact with the face during wear, which can cause discomfort. Furthermore, once the protective mirror inside the mask is worn or broken, the entire mask needs to be replaced, which greatly increases costs. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and provide a high-efficiency protective gas mask for nuclear radiation environment. By setting a clamp on the top of the mask, the clamp is fixed to the front of the wearing frame by a fixing member, so that there is a certain gap between the mask and the user's face, which improves the wearing comfort. At the same time, the mask is detachable and replaceable, so it can be easily replaced once it is worn or broken, thus reducing costs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A high-efficiency protective gas mask for use in nuclear radiation environments includes a mask body, which comprises a face shield and a wearing frame. The face shield is fixed to the user's face by the wearing frame. A clamp is provided at the top of the face shield, and the clamp is fixedly connected to the front side of the wearing frame by a fixing member. This invention, by providing a clamp at the top of the face shield and fixing it to the front side of the wearing frame by a fixing member, creates a certain gap between the face shield and the user's face, improving wearing comfort. Simultaneously, the face shield is detachable and replaceable, allowing for easy replacement in case of wear or breakage, thus reducing costs.

[0007] Furthermore, the clamping component includes a pad and a clamping plate, with the face shield positioned between the pad and the clamping plate. The pad is located between the face shield and the wearer's frame. The pad provides protection for the face shield during installation, while also creating a gap between the face shield and the user, preventing direct contact between the face shield and the user's face. The clamping plate and the pad work together to secure the face shield.

[0008] Furthermore, the fasteners include connecting screws, locking nuts, and caps. The connecting screws are evenly distributed and connected to the front side of the wearer. The gasket has a connecting hole one corresponding to the connecting screw, the face shield has a connecting hole two corresponding to the connecting screw, and the clamping plate has a stepped hole corresponding to the connecting screw. The connecting screw passes through connecting hole one, connecting hole two, and the stepped hole. The locking nut is screwed into the end of the connecting screw and tightened in the stepped hole. The cap is then tightened in the stepped hole. First, the face shield is positioned between the gasket and the clamping plate. Then, the face shield is installed by sequentially passing the connecting screw through connecting hole one, connecting hole two, and the stepped hole. The locking nut is then screwed into the connecting screw and tightened in the stepped hole, thus fixing the face shield to the front side of the wearer. Finally, the cap is tightened in the stepped hole, thereby sealing the opening on the front side of the stepped hole, preventing debris from entering the stepped hole, and also increasing the aesthetics of the face shield.

[0009] Furthermore, the cover is equipped with a connecting post, and the connecting post has a threaded hole corresponding to the connecting screw. By screwing the connecting post into the end of the connecting screw, the cover is tightly sealed in the stepped hole. The threaded hole is provided corresponding to the connecting screw. When installing the cover, the threaded hole and the threaded connection of the connecting screw allow the cover to be screwed into the stepped hole for fixation, thereby achieving the closure of the stepped hole.

[0010] Furthermore, the frame includes a mounting part and a wearing part. The mounting part is connected to the front of the wearing part, and a buffer zone is formed between the wearing part and the mounting part. The wearing part fits snugly against the user's face, and the face shield is fixedly connected to the front of the mounting part. The wearing part fits tightly against the user's face, and the mounting part is used to mount and connect the face shield. The buffer zone formed between the mounting part and the wearing part prevents the mounting part from directly impacting the wearing part when subjected to force, thus providing protection for the user. Simultaneously, it creates a certain distance between the face shield and the user's face, improving wearing comfort.

[0011] Furthermore, the buffer zone is equipped with an elastic cushioning section. This elastic cushioning section acts as a buffer, preventing the face shield from directly contacting the user's face after being subjected to force, thus providing better protection for the user's face.

[0012] Furthermore, the wearing area has evenly distributed ventilation holes. The ventilation holes increase the breathability of the wearing area, ensuring wearing comfort.

[0013] Furthermore, the rear end of the wearer is connected to an elastic band. The elastic band facilitates the attachment of the wearer to the user's face.

[0014] Furthermore, the face shield is made of lead glass. The use of lead glass provides radiation protection.

[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0016] This invention features a clamping component at the top of the face shield, which is fixed to the front of the wearer's frame by a fastener, creating a certain gap between the face shield and the user's face, thus improving wearing comfort. Additionally, the face shield is detachable and replaceable, allowing for easy replacement if worn or broken, thereby reducing costs.

[0017] In this invention, the clamping component includes a pad and a clamping plate. The face shield is positioned between the pad and the clamping plate, and the pad is located between the face shield and the wearer's frame. The pad provides protection for the face shield during installation. Simultaneously, the pad creates a certain distance between the face shield and the user, preventing direct contact between the face shield and the user's face. The clamping plate and the pad work together to secure the face shield.

[0018] In this invention, the fixing components include connecting screws, locking nuts, and caps. The connecting screws are evenly distributed and connected to the front side of the wearer. A first connecting hole is provided for the gasket corresponding to the connecting screw, a second connecting hole is provided for the face mask corresponding to the connecting screw, and a stepped hole is provided for the clamping plate corresponding to the connecting screw. The connecting screws pass through the first connecting hole, the second connecting hole, and the stepped hole. The locking nut is screwed into the end of the connecting screw and tightened in the stepped hole. The cap is then tightened in the stepped hole. First, the face mask is positioned between the gasket and the clamping plate. Then, the face mask is installed by sequentially passing the connecting screws through the first connecting hole, the second connecting hole, and the stepped hole. The locking nut is then screwed into the connecting screw and tightened in the stepped hole, thus fixing the face mask to the front side of the wearer. Finally, the cap is tightened in the stepped hole, thereby closing the opening at the front of the stepped hole, preventing debris from entering the stepped hole, and also improving the aesthetics of the mask.
