发明名称 Air-burst drain plunger
摘要 An affordable plumbing device that uses a compressed gas and a burst disk having a relatively even surface of substantially uniform thickness to produce a sudden discharge of energy to forcibly act against any obstruction that may interfere with the proper function of a drain. The plumbing device has a cylindrical chamber for receiving the compressed gas and may generally take the shape of a plunger, which is flexible to use and is easy to store. A portion of the chamber forms a receiving chamber with the burst disk for harnessing and directing the energy of the compressed gas to clear the drain.
