Abstract:
The purpose of the present invention is to provide a shower head capable of mixing sufficient air bubbles into a liquid. The present invention includes an air-bubble liquid generating means 4 that mixes air bubbles into a liquid to generate an air-bubble mixed liquid. The air-bubble liquid generating means 4 includes a rectification piece 111 that is disposed inside an air-bubble mixing room BR and a plurality of air introduction paths 112 through which air is made to flow into the air-bubble mixing room BR. The rectification piece 111 includes: a rectification nozzle disc 114 that is fixed in a water-sprinkler cylindrical section 97; a plurality of liquid squeezing holes 117 that are formed in the rectification nozzle disc 114 and from which the liquid is injected into the air-bubble mixing room BR; and a plurality of rectification piece plates 116 that are formed on the rectification nozzle disc 114 and that protrude toward the inside of the air-bubble mixing room BR. Each of the rectification piece plates 116 protrudes toward the inside of the air-bubble mixing room BR with a mixing gap GP provided with respect to a water-sprinkler nozzle plate 96. Each of the rectification piece plates 116 turns the liquid injected from each of the liquid squeezing holes 117 into a turbulent flow, at a protruding end 116D.
