The working principle of the device is briefly explained based on the structure as follows:

when the headband is adjusted by inflation: the elastic pressing body 31 is rotated to enable the air inlet 312 to be aligned and communicated with the external communication port 3216 (the air inlet 312 is opened to ensure that air can smoothly enter the air cavity 311); the elastic pressing body 31 is pressed, the gas in the air cavity 311 is pressed into the air channel structure 323 through the air guide structure 313, and enters the cavity of the body 321 on the upper side of the partition plate 325 through the air vent 324, the partition plate 325 moves in the direction away from the air channel structure 323 under the action of pressure difference, at the moment, the elastic resetting piece 326 is compressed, a gap for air to pass is formed between the partition plate 325 and the air channel structure 323 (namely, the air hole 3251 is opened), and the air enters the profiling air bag 2 through the gap, the air hole 3251, the air outlet 327 and the air guide tube 21 to inflate the profiling air bag (see fig. 5); after the primary inflation is finished, under the action of the elastic force provided by the elastic resetting piece 326 and the pressure difference, the partition plate 325 moves towards the air channel structure 323 to reset, the partition plate 325 is abutted against the end part of the air channel structure 323, the air hole 3251 is sealed, the air entering the profiling air bag 2 can be prevented from leaking, and the function of one-way conduction is achieved. At the moment, air enters the air cavity 311 again through the air inlet 312 to recover the initial state, and the elastic pressing body 31 can be repeatedly pressed for multiple times as required, so that the profiling air bag 2 is expanded to be tightly attached to the head of the user, and the intelligent head-mounted device is fixed on the head of the user; after the inflation is completed, the elastic pressing body 31 is rotated to displace the air inlet 312 from the outside communication opening 3216 in the circumferential direction (close the air inlet 312).

When the headband is adjusted through deflation, the pressing type inflating structure 3 is screwed, the pressing type inflating structure 3 moves axially relative to the air duct 21, so that the air vent 22 is exposed and communicated with the atmosphere, and the profiling air bag 2 is extruded to deflate; the air quantity of the profiling air bag 2 can be properly reduced according to the requirement of a user on comfort; after the deflation, the pressing type inflating structure 3 is reversely screwed, so that the deflation holes 22 are closed.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
