发明名称 Water ejectable umbrella
摘要 A water ejectable umbrella includes a water conduit which is disposed in a tubular stem and which has axially extending water drawing and expelling ducts that are communicated with each other by a transit chamber formed in a handle end portion of the stem. A plunger has a plunger head which is disposed in and which is movable relative to the transit chamber to perform a drawing stroke, during which a reduced pressure is created in the chamber for drawing water through the water drawing duct into the chamber, and an expelling stroke, during which the water in the chamber is pressurized to rush through the water ejecting duct so as to be ejected out of a spout proximate to an upper end of the stem.
