[0039] Working principle: When in use, just wear the device on the head. The top of the head touches the rubber top plate 25, causing the trapezoid-shaped sliding block 20 to move upward. At this time, the positive trapezoid-shaped sliding blocks 19 on both sides of the trapezoid-shaped sliding block 20 move towards the trapezoid-shaped sliding block 20, so that the arc-shaped iron sheet 21 moves inward, driving the strip-shaped airbag 11 to fit the user's scalp. The setting of the pawl 16 prevents the trapezoid-shaped sliding block 20 from moving and causing the device to fall off the user's head when the user shakes up, down, left, or right. After wearing, just start the blower inside the support plate 8. The gas blown out by the blower causes the strip-shaped airbag 11 to expand intermittently, massaging the wearing part of the user. If you want to remove the device, just press the column 13 to make the pawl 16 disengage from the outer wall of the ratchet 14, and the trapezoid-shaped sliding block 20 can move downward by its own gravity. At this time, the positive trapezoid-shaped sliding block 19 moves in the opposite direction, causing the strip-shaped airbag 11 to disengage from the user's head. The overall device simplifies the wearing process and avoids discomfort caused by long-term wearing.
