In order to facilitate the controller 24 to control the air pressure in the mask body 11, so that the mask body 11 always has a certain degree of micro positive pressure, the unit seat 131 is further provided with an air pressure sensor 132, and the air pressure sensor 132 can detect the air pressure difference between the inner side and the outer side of the oral mask body 1; the air pressure sensor 132 is connected to the controller 24. The controller 24 can determine whether a slight positive pressure is formed inside the cover body 11 relative to the outside of the cover body 11 according to the detection value of the air pressure sensor 132, so that the controller 24 can control the flow rate of the air pump 21 conveniently.

Further, the gas pipe 3 is provided with a branch pipe 31, and the branch pipe 31 is provided with a relief valve 32 and a filter unit 33. The branch pipe 31 and the pressure release valve 32 are arranged to prevent the breathing system from being out of control to cause the internal air pressure of the mask body 11 to be too high, and the air pressure of the pressure release valve 32 in the branch pipe 31 can be automatically opened to release the pressure when reaching a certain threshold value, so that the air pressure in the air pipe 3 (namely the air pressure in the mask body 11) cannot exceed the certain threshold value.

The neck hanging part 2 comprises a shell 25, and the air pump 21, the power supply 22, the filtering device 23 and the controller 24 are all arranged in the shell 25. The shell 25 is a symmetrical U-shaped structure as a whole, and the width of the area in the U-shaped structure in the direction perpendicular to the symmetry line is gradually widened and then gradually narrowed in the direction from the bottom of the U-shaped structure to the two ends of the U-shaped structure along the symmetry line; in addition, as seen from the side of the housing 25, the two side portions 251 thereof extend straight, and the middle portion 252 thereof is offset from the side portions 251 thereof with respect to the two side portions 251 of the housing 25; the middle part 252 of the shell 25 is thin and the two side parts 251 are thick, when the shell is worn, the middle part 252 is in contact with the back neck of a user, the two side parts 251 are hung on the front side of the user and are arranged on the two sides of the neck of the user, the design of the shell 25 accords with ergonomics, and the neck hanging part 2 has good wearing comfort after being worn on the neck of the user.
