[0035] The hook slide box 62 includes a box body 621 that is slidably connected to the metal hook plate of the hook strap 61. A constraint slider 622 is slidably connected to the front of the inner wall of the box body 621 by a spring. The constraint slider 622 is located on the left side of the metal hook plate of the hook strap 61.

[0036] The adsorption kit 63 is provided inside the box body 621. The adsorption kit 63 includes a permanent magnet block 631 fixedly connected inside the box body 621.

[0040] The inner rotating column of the connecting component 4 is provided with a mandibular rotation stop component 7. The mandibular rotation stop component 7 includes a three-sided fixing band 71 fixedly connected to the bottom of the inner rotating column of the connecting component 4. The three-sided fixing band 71 is an elastic band. The front of the three-sided fixing band 71 is fixedly connected to the bottom of the mask body 1 through the elastic band. The end of the three-sided fixing band 71 is fixedly connected to a rotation stop box 72. The rotation stop box 72 includes a main box 721 fixedly connected to the three-sided fixing band 71. The bottom of the main box 721 is slidably connected to a ratchet slide column 722 through a spring. A ratchet gear is fixedly connected to the outer surface of the ratchet slide column 722. A ratchet strip 723 is slidably connected inside the main box 721. The ratchet strip 723 and the ratchet gear of the ratchet slide column 722 mesh with each other. The end of the ratchet strip 723 is fixedly connected to the bottom of the inner rotating column of the connecting component 4 on the other side.

[0041] In use, the mask body 1 is placed on the user's mouth and nose area, and then the notch buckle 32 is inserted into the horizontal locking box 31. When the bottom of the notch buckle 32 passes the top of the vertical locking block 33, the bottom of the notch buckle 32 presses against the bottom of the vertical locking block 33, and the bottom of the vertical locking block 33 presses against the first arch bridge plate 34. The first arch bridge plate 34 undergoes elastic deformation. Subsequently, when the notch at the bottom of the notch buckle 32 contacts the top of the vertical locking block 33, the vertical locking block 33 resets under the elastic force of the first arch bridge plate 34. The vertical locking block 33 abuts against the notch buckle 32 from the vertical direction, thereby restraining the notch buckle 32. At the same time, the end of the notch buckle 32 presses against the abutting rod 351. The abutting rod 351 slides and drives the relay rod 352 to rotate, thereby pushing the constraint rod 353 to slide in the opposite direction. The end of the constraint rod 353 abuts against the back of the vertical locking block 33, thereby restraining the vertical locking block 33. At the same time, the abutting rod 351 restrains the end of the notch buckle 32.

[0042] Pull the sliding box 64 to the top of the user's head, insert the metal hook plate of the hook strap 61 into the box body 621, and push the constraint slider 622 to compress the spring after the hook strap 61 contacts the constraint slider 622. Then, when the end of the hook strap 61 moves away from the constraint slider 622, the constraint slider 622 returns to its original position, thereby constraining the hook strap 61.

[0043] Pull the bottom of the three-sided fixing strap 71 to the user's chin area, insert the ratchet strap 723 into the main box 721, the ratchet strap 723 and the ratchet slide 722 mesh with each other, then turn the ratchet slide 722 to make the ratchet slide 722 rotate and drive the ratchet strap 723 to slide, thereby tightening the chin lock assembly 7.

[0044] During the use of the mask body 1, the adhesive tape 51 is subjected to tension, which causes the force sensor of the monitoring component 5 to transmit the tension data of the adhesive tape 51 to the control circuit of the carrier box 52 in real time. Based on the feedback tension data, the control circuit of the carrier box 52 adjusts the current through the adsorption electromagnet 65, thereby adjusting the electromagnetic force of the adsorption electromagnet 65. The electromagnetic force generated by the adsorption electromagnet 65 attracts the permanent magnet block 631, which in turn drives the permanent magnet block 631 to slide. The permanent magnet block 631 drives the entire hook slide box 62 to slide. At the same time, the adsorption electromagnet 65 attracts and pulls the tape head 66, tightening the restraint tape of the vertical restraint component 6 located on the front, thereby improving the restraint effect of the vertical restraint component 6 and achieving stable vertical restraint.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
