Title:
AIR INTAKE VALVE AND BUFFER AIRBAG DEVICE HAVING AIR INTAKE VALVE
Document Type and Number:
WIPO Patent Application WO/2023/082525
Kind Code:
A1
Abstract:
Provided is an air intake valve (10), which is mounted on a buffer airbag device (200). An air intake hole (134), an air-passing hole (133) and an air output hole (112) are sequentially formed in the air intake valve (10), wherein one side of the air intake hole (134) is in communication connection with the air-passing hole (133), and the other side of the air intake hole is in communication with the outside; the air output hole (112) is in communication with the buffer airbag device (200), the air intake hole (134) and the air-passing hole (133); and the air intake valve (10) comprises a ball (12), the ball (12) being movably accommodated in the air-passing hole (133). When the buffer airbag device (200) is pressed in a compressed state, under the action of air pressure, the ball (12) moves towards the air intake hole (134) in the air-passing hole (133) and blocks the air intake hole (134), such that the air intake hole (134) is in a closed state; and when the buffer airbag device (200) is released and changes from the compressed state to a released state, under the action of the pressure difference between the outside and the interior of the buffer airbag device (200), the ball (12) moves towards the air output hole (112) in the air-passing hole (133) and opens the air intake hole (134), such that the air intake hole (134) changes from the closed state to an air-passing state. Further provided is a buffer airbag device (200).
