Abstract
A shower head comprises a jet nozzle for jetting pressurized water supplied, a shower main body having ejector mechanisms consisting of the jet nozzle and an air-liquid mixing tube provided via an air suction member, a discharge outlet of the air-liquid mixing tube opening to a shower discharge member, and an annular projecting member projecting from the shower discharge member so as to surround the discharge outlet, wherein an air absorption hole of the air absorption member is made in an outer side section of the annular projecting member.
Claims13
A shower head comprising:
- a shower head main body having one or a plurality of Venturi mechanisms for generating a negative pressure with pressurized water supplied, a discharge outlet of said one or plurality of Venturi mechanisms opening to a shower discharge portion;
- an air absorption path for communicating a throat portion of said one or plurality of Venturi mechanisms with atmosphere;
- and
- an annular projecting member projecting from the shower discharge portion so as to surround the discharge outlets,
- wherein an air absorption hole of the air absorption path is located outside a space defined within the annular projecting member.

A shower head comprising:
- nozzle provided at a distal end of a shower head main body to which pressurized water is supplied, for jetting out the pressurized water;
- an air absorption portion having a space section located on an exit side of the jet nozzle, for suctioning air from outside the space section;
- an air-liquid mixing tube for discharging the pressurized water and the air while mixing them together;
- an annular projecting member provided on a discharge outlet side of the air-liquid mixing tube, so as to surround the discharge outlet;
- a second fluid suction portion having a second space section situated on the discharge outlet side of the air-liquid mixing tube, for suctioning a second fluid from outside into the second space section;
- a second air-liquid mixing tube for discharging the pressurized water and the air while mixing them together;
- an air absorption hole of the air absorption portion located outside a space defined within the annular projecting member;
- and
- a fluid suction hole of the second fluid suction portion located inside the space defined within the annular projecting member,
- wherein the pressurized water is supplied to the jet nozzle when an edge of an end of the annular projecting member is brought into contact with an object to be washed.
