DEVICE FOR PREVENTING THE WATER IN-FLOW FOR EXHAUST AIR PURIFIER OF MUFFLER CHAMBER SYSTEM

摘要

This invention is about the device for preventing water in the exhaust clarifier of absorbing chamber of vacuum cleaner from inflow. The device contains the air injection pipe(230) screwed up the female screw(146b')(150a') formed on the one end of air blowoff pipe(146') and air drain pipe(150'); and the inflow preventing device(235) for controlling air flow in the air injection pipe(230). The air injection pipe(230) with a hollow in its inside contains the body formed a male screw(210) on its peripheral surface and the conical head attached with many openings(220) radially communicating with a hollow(205). The inflow preventing device(235) is adhered closely to one end of the air injection pipe(230) to close and open the opening(220).
