CYLINDER ASSEMBLY AND DISPENSER PUMP USING THE SAME

摘要

The cylinder assembly includes a first body, a second body and a coupling mechanism. The first body is of a tubular shape and has a valve set at a bottom end thereof. The valve set includes a valve, an elastomer and a passage. The second body has a ring with an outline fitting the valve.;The coupling mechanism includes a first coupling piece disposed on the first body and a second coupling piece disposed on the second body and is used for detachably coupling the first and second bodies. The valve is located in an aperture of the ring, the elastomer flexibly supports the valve to abut against the ring and seal up the aperture or retracts to open the aperture for allowing liquid to flow into the first body through the passage.
