  • Publication number: 20110225714
    Abstract: A drain cleaning and clearing assembly is revealed. The assembly includes an elastic tube and a cleaning head mounted to a sleeve-jointed part on one end of the elastic tube. The cleaning head includes an integrated inner tube and an integrated outer tube. A tubular opening is disposed on and penetrating two ends of the inner tube while a water inlet is arranged around the outer tube. The water inlet is connected with a columnar water outlet between the inner tube and the outer tube. A projecting stop flange is provided protruding from the bottom end of the inner tube. Thus water flow is ejected from the tubular opening of the cleaning head and the columnar water outlet respectively to form a water jet and radial water flow. Thereby stuff clogged in a drain is removed and a drain wall is cleaned by water flow.

  • 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.
