Adding the flexible material into the forehead support frame 3 is beneficial to improving the adjustment capability of the forehead support frame 3 .

[0026] In this embodiment, an annular portion is formed inside the fixing portion 31, and a groove 311 is formed on the inner wall of the annular portion; a protrusion 111 corresponding to the groove 311 is formed on the outer peripheral side of the frame assembly 1, and the annular portion is sleeved on the outer peripheral side of the frame assembly 1, and the groove 311 is engaged with the protrusion 111.

[0027] Specifically, in this embodiment, the number of grooves 311 can be one or more, and the number of protrusions 111 corresponds to the number of grooves 311. Preferably, the inner wall of the annular portion (i.e., the mounting ring) is provided with two mutually symmetrical grooves 311, and the shape and size of the annular portion are just adapted to the shape and size of the corresponding connection on the frame assembly 1, and the outer peripheral side of the frame assembly 1 is provided with a protrusion 111 that matches the shape and position of the two grooves 311. When assembling and fixing, the annular portion is inserted into the appropriate position on the outer side of the frame assembly 1, and the protrusion 111 is inserted into the corresponding groove 311, so that the connection and fixation between the forehead support frame 3 and the frame assembly 1 can be achieved. Of course, in some other embodiments, a protrusion can also be provided on the inner wall of the annular portion, and a groove corresponding to the protrusion 111 can be provided on the outer side of the frame assembly 1, thereby also achieving a stable connection between the forehead support frame 3 and the frame assembly 1. In this embodiment, a symmetrical fixing ring can also be provided on the fixing portion 31, and the fixing ring can be connected to some other fixing components, so that the breathing mask can be firmly fixed to the user's head through the cooperation of the fixing ring and the fixing components.

[0028] In this embodiment, the outer peripheral side of the air intake pipe 2 is connected with a boss 21 and a blocking edge 22, and the boss 21 and the blocking edge 22 are spaced apart along the axial direction of the air intake pipe 2; the frame assembly 1 is provided with a mounting cavity 113 connected to the air guide cavity, the air intake pipe 2 extends into the mounting cavity 113 and is fixed to the frame assembly 1, and the side of the boss 21 facing the blocking edge 22 abuts against the wall surface of the air guide cavity, and the side of the blocking edge 22 facing the boss 21 abuts against the outer side wall of the frame assembly 1. The thickness of the boss 21 is 0.2 to 0.8 mm. A guiding inclined surface is formed on the side of the boss 21 away from the blocking edge 22.

[0029] Specifically, the distance between the boss 21 and the blocking edge 22 is equal to the length of the installation cavity 113 in the axial direction. The boss 21 and the blocking edge 22 are respectively in contact with the frame assembly 1 at the port edges at both ends of the installation cavity 113, so that the intake pipe 2 and the frame assembly 1 can be firmly fixed. The thickness of the boss 21 can refer to the distance from the farthest point of the boss 21 in the axial direction of the intake pipe 2 to the outer peripheral side of the intake pipe 2. The thickness of the boss 21 can be 0.3 mm, 0.5 mm, 0.6 mm, etc., which is not limited here. The size of the installation cavity 113 is adapted to the size of the body of the air intake pipe 2. During assembly, the air intake pipe 2 can be inserted into the installation cavity 113 from outside the frame assembly 1. The boss 21 and the air intake pipe 2 can be squeezed and deformed in the process of moving along the installation cavity 113. When the air intake pipe 2 and the installation cavity 113 are aligned in the final position, the air intake pipe 2 can automatically return to its original shape because it is no longer squeezed. When the shape of the air intake pipe 2 is restored to its original shape, the boss 21 and the frame assembly 1 are automatically abutted and engaged. In this embodiment, a guiding bevel is set on the side of the boss 21 away from the blocking edge 22, that is, a bevel chamfer is formed on the side of the boss 21 away from the blocking edge 22, so that the air intake pipe 2 can be more easily inserted into the installation cavity 113 under the guiding effect of the guiding bevel, which is conducive to reducing the difficulty of the assembly operation.

[0030] In this embodiment, the ventilation device can be a ventilator. The frame assembly 1 is provided with an exhaust hole 112. When the ventilation device is connected to the air inlet pipe 2 for operation, the gas flows from the ventilation device to the air inlet pipe 2 to the air guide cavity for the user to inhale; when the user exhales, the ventilation device stops supplying gas, and the gas exhaled by the ventilation device passes through the air guide cavity and is discharged to the outside of the breathing mask along the exhaust hole 112. It can be understood that in some other embodiments, the exhaust hole 112 can also be set on the ventilation pipe, which is not limited here. Further, in this embodiment, a plurality of exhaust holes 112 can be set, and a plurality of exhaust holes 112 are distributed around the periphery of the installation cavity 113 to ensure that the gas exhaled by the user after exhalation can be discharged from the body in time.
