An automatic height-adjusting pillow cushion comprises an outer case (1), an airbag core (2) placed in the outer case (1), a control device (4), and an inflation device. The airbag core (2) at least comprises one airbag (3), wherein respective air chambers of each airbag (3) are mutually independent, and each airbag (3) is provided with an air pressure sensor (6) configured to detect an air pressure in the air chamber thereof. The airbag (3) is connected to the inflation device (5) via an air pipe (7). The air pipe (7) is connected to an electronic control valve (8) in series. The electronic control valve (8), the air pressure sensor (6), and the inflation device (5) are respectively electrically connected to the control device (4). The pillow cushion detects the air pressure in the air chamber of each of the airbags (3) via the pressure sensor (6), and then provides feedback to the control device (4). The control device (4) controls the inflation device (5) to operate so as to inflate the airbag (3) or controls the electronic control valve (8) to perform a deflation operation, thereby changing an air volume in the airbag (3) to realize an automatic height adjustment for the pillow cushion. By controlling inflation or deflation of different airbags (3), the present invention enables a height variation in different areas of the pillow cushion, and such height variation cycles sequentially and rhythmically. Therefore, a user can relax from a nervous state, and the rhythmical cycle tends to cause the user to fall asleep, thereby achieving a hypnotic effect. |
