ONE WAY VALVE ASSEMBLY
First Claim
1. A one way valve assembly, comprising:
- a base, comprising a base inner surface, a first lower hollow and a second lower hollow which are recessed at the base inner surface, and an inlet connected through the first lower hollow;
a cover, comprising a cover inner surface, a first upper hollow, a second upper hollow and a connecting path which are recessed at the cover inner surface, an outlet, and an exhaust nozzle located in the first upper hollow, wherein positions of the first upper hollow and the second upper hollow respectively correspond to positions of the first lower hollow and the second lower hollow, the first upper hollow is connected through the second upper hollow via the connecting path, and the outlet is connected through the second upper hollow; and
a valve member, disposed between the base and the cover, the valve member having a first zone, a second zone, and a third zone corresponding to the first upper hollow, the second upper hollow, and the connecting path, and comprising a valve nozzle located between the second lower hollow and the second upper hollow, wherein the first zone is suitable to deform towards the first lower hollow or the first upper hollow, the second zone is suitable to deform towards the second upper hollow, and the third zone is suitable to deform towards the connecting path, wherein;
in an initial state, the valve member is suitable to seal the first lower hollow and the second lower hollow, after a gas enters the first lower hollow from the inlet, the first zone of the valve member is pushed by the gas to deform towards the first upper hollow so as to abut against the exhaust nozzle, then the third zone of the valve member is pushed by the gas to deform towards the connecting path, and then the second zone of the valve member is pushed by the gas to deform towards the second upper hollow, such that the gas flows from the first lower hollow through the second lower hollow, the valve nozzle, and the second upper hollow sequentially, and then is exhausted from the outlet,in an exhaust state, the valve member is recovered to close a connected state between the first lower hollow and the second lower hollow and a connected state between the second lower hollow and the second upper hollow, and the gas located between the cover and the valve member leaves from the one way valve assembly from the exhaust nozzle automatically.

Abstract
A one way valve assembly including a base, a cover, and a valve member is provided. The base includes a first and a second lower hollows and an inlet connected through the first lower hollow. The cover includes a first and a second upper hollows, a connecting path, an outlet, and an exhaust nozzle. Positions of the first and the second upper hollows correspond to positions of the first and the second lower hollows. The first upper hollow is connected through the second upper hollow via the connecting path. The outlet is connected through the second upper hollow. The valve member is disposed between the base and the cover. The valve member has a first zone, a second zone, and a third zone corresponding to the first and the second upper hollows and the connecting path, and includes a valve nozzle between the second lower hollow and the second upper hollow. The first zone can deform towards the first lower hollow or the first upper hollow. The second zone can deform towards the second lower hollow or the second upper hollow. The third zone can deform towards the connecting path.
