The utility model discloses a washing unit says in semi -automatic chamber, including cylinder, push rod and removal piston, move the piston and is connected with the push rod, move the piston and the push rod is movably installs in the cylinder, and the needle mouth of cylinder is respectively with the imbibition pipeline with wash the pipeline and be connected, and the tip of cylinder is closed for the space at push rod place is the vacuum in the cylinder, the cylinder respectively through check valve and imbibition pipeline with wash the pipeline and be connected, the cylinder passes through imbibition in the check valve follow imbibition pipeline, the cylinder is through the check valve to washing pipeline towards liquid. Because the space at push rod place be the vacuum in the cylinder, and the cylinder is respectively through the check valve with the imbibition pipeline with wash the pipeline and be connected for the cylinder washes the back in manual propelling movement, because the vacuum in the cylinder forms the negative pressure, the activity piston can return voluntarily and move back after unclamping the hand, and through check valve from imbibition pipeline imbibition. Through the negative pressure automatic return to move back make this washing unit realize semi -automatic washing, has practiced thrift the pumpback time, and has made things convenient for the operation, provide work efficiency.
