Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
182 words
A shower device having a water injecting portion comprising a casing adapted to be connected to a water source and including a chamber to which water is supplied under pressure, a nozzle plate having a plurality of nozzles formed therein, a cover having an outer end face formed with water jet holes corresponding in number to said nozzles and aligned therewith, said face of said cover being spaced at all points from said plate so as to form a continuous air chamber therebetween, said cover being further formed with a plurality of individual air inlet openings around the circumference thereof directly communicating with said air chamber for admitting air into said chamber, and means for securing said cover and said plate, in said spaced relationship, to said casing, said securing means comprising screw members fixedly attaching said cover to said casing, said cover being formed with an annular recess for receiving said plate, and said casing including a cylindrical outer end portion which engages said plate and forces the same against a wall of said recess to retain said plate in position.
Claim 2
Dependent Claim
182 words
A shower device having a water injecting portion comprising a casing adapted to be connected to a water source and including a chamber to which water is supplied under pressure, a nozzle plate having a plurality of nozzles formed therein, a cover having an outer end face formed with water jet holes corresponding in number to said nozzles and aligned therewith, said face of said cover being spaced at all points from said plate so as to form a continuous air chamber therebetween, said cover being further formed with a plurality of individual air inlet openings around the circumference thereof directly communicating with said air chamber for admitting air into said chamber, and means for securing said cover and said plate, in said spaced relationship, to said casing, said securing means comprising screw members fixedly attaching said cover to said casing, said cover being formed with an annular recess for receiving said plate, and said casing including a cylindrical outer end portion which engages said plate and forces the same against a wall of said recess to retain said plate in position.
Claim 3
Dependent Claim
48 words
The shower device of claim 1 in which said nozzles and water jet holes are tapered to have a smaller diameter towards the outlet end of said device, wherein the outlet side of each nozzle is smaller in diameter than the inlet side of each water jet hole.
