Document Type and Number:
WIPO Patent Application WO/2021/115341
Kind Code:
A1
Abstract:
A hookah air valve, comprising an air valve element (1). The air valve element (1) comprises an air suction channel (2) and an air blowing channel. The air suction channel (2) is provided with a first sealing member (7). The first sealing member (7) enables the air suction channel (2) to be in a normally closed state. The air blowing channel comprises an air blowing segment (3), a sealing member moving segment (4), and an air outlet segment (5) arranged in sequence. The air blowing segment (3) communicates with the air outlet segment (5) by means of the sealing member moving segment (4). The sealing member moving segment (4) is provided with a second sealing member (8). Under normal conditions, the air blowing segment (3) is not in communication with the air outlet segment (5). When a certain amount of gas is input into the air blowing channel through the air blowing segment (3), the second sealing member (8) moves toward the air outlet segment (5), and enables the air blowing segment (3) to communicate with the air outlet segment (5). A hookah comprising the hookah air valve can be used for multiple persons to smoke and blow smoke simultaneously without affecting each other.
