A filter screen 22 is embedded on the inner wall of the mask body 2. The filter screen 22 performs secondary filtration on the air entering the inside of the mounting sleeve 4. A guiding sleeve 23 is provided on the inner wall of the mask body 2 by welding. A PC sunlight panel 24 is embedded inside the goggle 3.

[0027] When wearing this radiation protection mask, the user first fits the mask body to the face, and then comfortably fixes it to the head using the first and second telescopic belts 1501 to ensure a stable fit of the mask, providing a comprehensive radiation protection barrier for the face. During operation, the built-in filter 5 can effectively intercept tiny radioactive particles in the air and prevent them from entering the respiratory tract, thus protecting the user from radiation contamination. When the filter 5 needs to be replaced, the user pulls the C-shaped hook 1001 to separate the clamping block 10 to both sides, compressing the first elastic element and releasing the locking state of the filter 5. Then, the filter 5 can be easily removed from the mounting sleeve 4 by smoothly pulling it forward, realizing the quick replacement of the filter 5 without replacing the entire mask, significantly improving the convenience and economy of the mask. When replacing the new filter 5, just place it into the mounting sleeve 4 and release the C-shaped hook 1001.

[0029] When the filter 5 needs to be replaced, the traction rope 13 is pulled downward, so that the connecting rod 11 drives the clamping block 10 to move toward the side away from each other, and then the two clamping blocks 10 are simultaneously separated from the filter 5, so as to facilitate quickly taking out the filter 5, thereby improving the replacement efficiency.

[0030] Please refer to Figure 7 , a positioning block 18 is provided on the guide block 16 by welding, a second fixing rod 19 is provided on the positioning block 18 by welding, a limiting block 21 is slidably arranged on the second fixing rod 19, the limiting block 21 slides inside the guide block 16 and can contact with the first elastic band 15, a second elastic member 20 is sleeved on the second fixing rod 19, and two ends of the second elastic member 20 are respectively connected with the positioning block 18 and the limiting block 21.

[0031] Before wearing the radiation protection mask, the user first gently lifts the limiting block 21 upward to make it separated from the first elastic band 15. At this time, the second elastic element is stretched. Then, the user can flexibly adjust the distance between the first elastic band 15 and the mask body by moving the first elastic band 15 left and right, so as to realize the personalized adjustment of the tightness of the mask, make the radiation protection mask adapt to users with different head shapes and face shapes, improve the versatility and comfort of the product. After adjusting the first elastic band 15 to an appropriate position, the user only needs to release the limiting block 21, and the second elastic element will naturally rebound, driving the limiting block 21 to reset downward and re-clamping the first elastic band 15 to maintain the set tight state, ensuring the stability and sealing performance of the mask during actual wearing.
