摘要 A vacuum pump valve includes a valve body and a suction element. The valve body includes a sealing platform sealedly attached on the container at the opening thereof, and a guiding sleeve upwardly extended from the sealing platform to form a suction channel, wherein the sealing platform has an operation hole formed thereon at a position within the suction channel and at least a through ventilating groove communicating the receiving cavity of the container with an exterior thereof. The suction element is disposed within the suction channel of the valve body, including an enlarged sealing head adapted to seal on the sealing platform to enclose the ventilating groove thereof, and a guiding shaft extended from the sealing head to slidably mount at the sealing platform at the operation hole to move the sealing head between a releasing position and a sealing position.
