Abstract

A shower head includes a handle and a head portion. The head portion includes shower holes. The handle includes an upstream bubble generator that generates minute bubbles in water. The head portion includes a downstream bubble generator that generates minute bubbles in water in the same manner as the upstream bubble generator. The upstream bubble generator includes a constriction and a tapered portion. The downstream bubble generator has a swirling flow mode. Since minute bubbles are generated on the upstream and downstream sides, the amount of minute bubbles mixed in water becomes larger. This allows for showering by effectively using the function of minute bubbles.

First claim

The invention claimed is:

1. A shower head, comprising a head portion that includes shower holes,
wherein minute bubble generators are disposed at positions on an upstream side and a downstream side in a water passage, wherein
the shower holes include a mist shower hole configured to release a mist shower,
the water passage includes an accommodation recess, the mist shower hole extending through a bottom of the accommodation recess,
the accommodation recess accommodates a swirling flow generating member,
the swirling flow generating member has an opening at an end closer to the mist shower hole,
drawing grooves are disposed on an outer circumference of the swirling flow generating member
an end of each of the drawing grooves includes a guide opening, the guide opening being connected to an internal space of the swirling flow generating member, and
the minute bubble generator on the downstream side includes the accommodation recess and the swirling flow generating member.

2. The shower head according to claim 1 , comprising a handle held by a user,
wherein the head portion is located proximate to a distal end of the handle.

3. The shower head according to claim 2 , wherein
the minute bubble generator on an upstream side of water is located in the handle, and
the minute bubble generator on a downstream side of the water is located in the head portion.

4. The shower head according to claim 3 , wherein
the minute bubble generator on the upstream side has a straight passage mode with a constriction so as to utilize a Venturi effect, and
the minute bubble generator on the downstream side has a swirling flow mode.

5. The shower head according to claim 3 , wherein the minute bubble generator on the upstream side includes a passage of a straight passage mode, the passage including constrictions.

6. The shower head according to claim 3 , wherein the minute bubble generator on the downstream side includes passages of a swirling flow mode.

7. A shower head, comprising a head portion that includes shower holes, wherein
minute bubble generators are disposed at positions on an upstream side and a downstream side in a water passage,
a bifurcated portion is disposed at a part of the water passage, and
a shower switch mechanism is disposed in a narrow section of the bifurcated portion.

8. The shower head according to claim 7 , wherein the minute bubble generator is disposed on each of an upstream side and a downstream side of the bifurcated portion.

9. The shower head according to claim 8 , wherein a switch button of the switch mechanism on a front surface of the head portion is shifted from a central position in a left-right direction.
