At the same time, the connecting rod 5 and the second disc 8 move downward at the same time, and the volute spring 10 is deformed by force. When the bottom of the second disc 8 is connected to the rotating shaft 4, the sensor 15 transmits the user's breathing signal collected by the ventilator to the motor 3 to control the operation of the motor 3. When the motor 3 is running, the rotating shaft 4 rotates at the same time, the gear-adjusting second disc 8 rotates, and the first disc 6 and the connecting rod 5 rotate. The connecting rod 5 is rotated at the same time, and the connecting rod 5 rotates inside the sleeve 9 and the rotating shaft 4. At this time, the telescopic belt 7 is rolled up around the outer wall of the connecting rod 5. At the same time, the telescopic belt 7 moves through the through groove 14 to tighten and relax the user's head. When it is not needed, the sleeve 9 is rotated in the opposite direction to make the rotating shaft 4 disengage from the rotating groove 12. At the same time, the telescopic belt 7 is reset by the spiral spring 10. When the staff needs to adjust the nose pad 18, the moving rod 17 is manually rotated to make the nose pad 18 in a suitable position inside the mask body 1. The above is the working principle.
