Abstract
A shower device having a water injecting portion consisted of a nozzle plate having a plurality of nozzles thereon and a cover having water jet holes of the same number positioned respectively to correspond to said nozzles at a given distance. Said nozzles and water jet holes are all tapered to have a smaller diameter towards the outlet side of the device. Between the cover and the nozzle plate, an air chamber is formed by means of which air is sucked in by the gushing water, and jetted out in a state of minute foam mixed with water. When the water jet strikes against one's body, the minute foam ruptures in succession generating minute pulsations and supersonic waves thereby to provide a massage and hot spring bath effect. The shower device is simple, easy to fabricate, and handy to use and disassemble for cleaning.
