  • Patent number: 7213273
    Abstract: A plunger includes a lever, a pipe, a rod passed through an axial hole of the pipe, a covering member, and a spring; the rod will be upwards displaced when the lever is pivoted upwards; the rod has a passage therein, and a head at an upper end for connection with an air pump; the covering member has a neck, and an outlet on a lower side; the pipe is inserted in the neck; two airtight rings are secured on an inner side of the neck; the rod is normally biased to a lowermost position by the spring; the lower end of the rod will block the outlet, and the passage will communicate with inside of the covering member when the rod is in lowermost position; when the lever is pivoted upwards, high-pressure air will escape through the outlet to push a blockage in a drain tube of a sink.

  • Patent number: 6032301
    Abstract: A plunger includes an upper base, a pressure ball under the upper base, a correlative tubular shaft extending vertically through the pressure ball, a handle pivotally connected with an upper end of the correlative tubular shaft, a connecting rod connects to the correlative shaft, and a lower end stopper threadably connected with the lower end of the connecting rod. The pressure ball can store air supplied by an air pump or compressor through an air inlet. The handle can be operated to let the air stored in the pressure ball flow through the correlative shaft, the connecting rod and the lower end stopper into a clogged pipe or drain for clearing passage with a large force of pressured air.
