PUMPING DEVICE

摘要

A pumping unit is operable between sucking and discharging states. The main body has a sucking channel, a discharging channel and at least one blocking mechanism. The sucking channel communicates with outside and an interior of the pumping unit, the discharging channel communicates with a receiving space of a receiving unit and the interior of the pumping unit, and one said blocking mechanism is arranged within the sucking channel to block the sucking channel selectively. Wherein, when the pumping unit is in the sucking state, the blocking mechanism unblocks the sucking channel, and the fluid enters the interior of the pumping unit; when the pumping unit is in the discharging state, the blocking mechanism blocks the sucking channel, and the fluid enters the receiving space. A pumping device is further provided for sucking a fluid from the receiving space and discharging the fluid to outside.
