Soap dispenser head

Abstract

An improved structure of a soap dispenser head to deliver a fixed amount of soap liquid and to prevent any leakage of soap liquid, essentially comprised of a graded trough on either side of a soap delivery head of a soap dispenser; a soap liquid inlet being provided on either side of the graded trough; a soap liquid outlet being provided at the bottom of the graded trough; a piston penetrating the graded trough, a cap being provided on the top of the graded trough, a ring seat being provided at the bottom of the piston ring of the piston; a coil being inserted on to the bottom of the ring seat, a stop being provided at the lower end of the piston; a retaining hole is provided at the lower end of the piston, a hole being provided on the stop for the retaining to penetrate through the stop and inserted into the retaining hole in the piston thus to position the stop in the lower end of the piston so that when the soap dispenser is depressed for the piston in the soap delivery head to move downward, the ring seat on the piston closes up the soap liquid inlet on either side of the graded trough of the soap delivery head to avoid continuous feeding of the soap liquid to deliver only a fixed amount of soap liquid while the sop completely closes up the soap liquid outlet once the piston returns to its original piston to prevent leakage of soap liquid.
