Abstract

A toilet deodorizer comprising a pump housing in the form of a cylinder 52 and a piston 54. The cylinder 52 is to be mounted on the movable toilet seat 14 of a conventional toilet. When sitting on the toilet seat, the toilet seat moves which causes a piston 54 to be moved within the cylinder 52 which causes liquid to be dispensed from a pump chamber 50 through an outlet valve 100 in contact with a deflector plate 134 which disperses the liquid within a wide area of the toilet bowl 10. When the user gets up from the toilet seat, the toilet seat is lifted which causes retraction movement between the piston 54 and the cylinder 52 which causes a new quantity of liquid to be pulled through an inlet valve 44 into the pump chamber while maintaining the outlet valve closed.
