[0025] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: A breathing mask fixing strap, including a connecting ring 1, a fixed box 2, and a forehead strap 3. An L-shaped block 5 is fixedly connected to the outer wall of the connecting ring 1. A card slot 4 is opened on the outer wall of the fixed box 2. A rotating column 10 is rotatably connected to the inner wall of the fixed box 2. One end of the forehead strap 3 is fixedly connected to the inside of the rotating column 10. A fixed block 6 is fixedly connected to the outer wall of the L-shaped block 5. A fixed column 7 is fixedly connected to the inside of the fixed block 6. A cardboard 8 is rotatably connected to the outer wall of the fixed column 7. A first spring 9 is fixedly connected to the outer wall of the cardboard 8. The end of the first spring 9 away from the cardboard 8 is fixedly connected to the outer wall of the L-shaped block 5. The outer wall of the cardboard 8 is slidably connected to the inner wall of the fixed box 2. The outer wall of the cardboard 8 is slidably connected to the inner wall of the card slot 4. The outer wall of the L-shaped block 5 is slidably connected to the inner wall of the fixed box 2. A fixing component is arranged on the outer wall of the forehead strap 3, and the fixing component is used to fixedly connect the other end of the forehead strap 3 to the breathing mask; the fixing component includes a first magic tape 11, and the lower surface of the first magic tape 11 is arranged on the upper surface of the forehead strap 3;

[0026] Specifically, the connecting ring 1 can play a role in fixing the L-shaped block 5, the L-shaped block 5 can play a role in fixing the fixed block 6, the fixed block 6 can play a role in fixing the fixed column 7, the fixed column 7 plays a role in rotating the cardboard 8, the first spring 9 plays a role in moving and resetting the cardboard 8, the rotating column 10 plays a role in connecting the forehead strap 3, and the first magic tape 11 can fix one end of the forehead strap 3 to the breathing mask.

[0027] Referring to Figure 1, a first strap 12 is fixedly connected to the outer wall of the connecting ring 1. A second magic tape 13 is provided on the upper surface of the first strap 12. A second strap 14 is fixedly connected to the outer wall of the connecting ring 1. A third magic tape 15 is provided on the upper surface of the second strap 14.

[0028] Specifically, the first strap 12 and the second strap 14 can be respectively fixed on the breathing mask through the second magic tape 13 and the third magic tape 15.

[0029] Refer to Figure 1 、 Figure 4 and Figure 5 , a head ventilation pillow 16 is slidably connected to the inner wall of the connecting ring 1. A fixing groove 17 is formed on the outer wall of the head ventilation pillow 16; a sliding column 19 is slidably connected to the inner wall of the connecting ring 1. A sliding groove 18 is formed on the inner wall of the connecting ring 1; a limiting piece 20 is fixedly connected to the outer wall of the sliding column 19. One end of the sliding column 19 is fixedly connected to a clamping block 21. The outer wall of the clamping block 21 is slidably connected to the inner wall of the fixing groove 17; a second spring 22 is slidably connected to the outer wall of the sliding column 19; one end of the second spring 22 is fixedly connected to the outer wall of the clamping block 21, and the other end of the second spring 22 is fixedly connected to the inner wall of the sliding groove 18;

[0030] Specifically, one end of the second spring 22 is fixedly connected to the outer wall of the clamping block 21 and the other end is fixedly connected to the inner wall of the sliding groove 18, which can prevent the sliding column 19 from rotating when sliding inside the connecting ring 1. The head ventilation pillow 16 can improve the comfort of the patient when wearing the breathing mask, especially for patients who need to wear the breathing mask for a long time.

[0031] Working principle: When using this mask, first fix the first strap 12 and the second strap 14 on the breathing mask through the second magic tape 13 and the third magic tape 15 respectively, and then wear it on the patient's head. Secondly, one end of the forehead strap 3 needs to be connected to the breathing mask through the first magic tape 11, and then the fixed box 2 is used to fix the end of the forehead strap 3 fixedly connected to the rotating column 10. When fixing the end of the forehead strap 3 fixedly connected to the rotating column 10, it will cause the outer wall of the L-shaped block 5 to slide on the inner wall of the fixed box 2, and at the same time, the outer wall of the clamping plate 8 will also contact the inner wall of the fixed box 2. When the outer wall of the clamping plate 8 contacts the inner wall of the fixed box 2, that is, during the process of the outer wall of the clamping plate 8 sliding on the inner wall of the fixed box 2, the clamping plate 8 will be forced to rotate on the outer wall of the fixed column 7 and exert pressure on the first spring 9, causing the first spring 9 to contract under force. When the clamping plate 8 slides to the inner wall of the card slot 4 during the sliding process, the clamping plate 8 will no longer be stressed at this time, and then the first spring 9 will rebound and reset, thereby fixing the fixed box 2, and thus completing the rapid installation of the forehead strap 3. The breathing mask is fixed through the forehead strap 3 from the patient's forehead, effectively enhancing the stability of the mask, maintaining a close fit between the mask and the face, ensuring airtightness and treatment effect. Through the mutual cooperation of the fixed box 2 and the clamping plate 8, it is convenient for rapid installation and improves the convenience of use. The head ventilation pillow pad 16 needs to be frequently replaced and cleaned during use, so it needs to be replaced quickly and installed quickly after replacement. When the head ventilation pillow pad 16 needs to be quickly disassembled, only need to pull the limit piece 20, causing the limit piece 20 to drive the sliding column 19 to slide inside the connecting ring 1. At this time, the clamping block 21 will slide out of the inner wall of the fixing groove 17 opened on the outer wall of the head ventilation pillow pad 16 and slide inside the sliding groove 18, so that the head ventilation pillow pad 16 is no longer limited and fixed, and thus the rapid disassembly of the head ventilation pillow pad 16 is completed. When the head ventilation pillow pad 16 that has been replaced or cleaned needs to be quickly installed, only need to slide the outer wall of the head ventilation pillow pad 16 inside the inner wall of the connecting ring 1. During the process of the head ventilation pillow pad 16 sliding inside the inner wall of the connecting ring 1, the clamping block 21 will be forced. The clamping block 21 will move under force and slide inside the sliding groove 18. At the same time, the movement of the clamping block 21 will cause the sliding column 19 to slide inside the connecting ring 1 and drive the limit piece 20 to move. The movement of the sliding column 19 also causes the second spring 22 to slide on the outer wall of the sliding column 19 and contract. When the clamping block 21 slides to the inner wall of the fixing groove 17 opened on the outer wall of the head ventilation pillow pad 16, the clamping block 21 will no longer be stressed at this time, and the second spring 22 will rebound and push the clamping block 21 to reset to fix the head ventilation pillow pad 16, thus completing the rapid installation of the head ventilation pillow pad 16. The design of rapid installation and disassembly enables medical staff to more easily remove the pillow pad from the fixing belt for cleaning and disinfection, which can keep the equipment clean and hygienic and reduce the risk of cross-infection.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
