Description

  The present invention relates to a shower head capable of improving a massage effect by changing the amount of water to be sprayed and applying it to the body.

  As a shower head, what was disclosed by patent document 1 is proposed conventionally. In this shower head, a watering cap is joined to an opening of a water chamber formed in the main body, and two blocking plates having two cutout portions are rotatably accommodated inside the water chamber. When the swirling water flow is applied to the rotor blade connected to the blocking plate via the shaft, the rotor blade, the shaft and the blocking plate are swirled, and the water supplied to the watering holes of the watering cap is intermittently changed. Since the intermittent flow of water is applied to the human body, the massage effect can be enhanced.

Japanese Utility Model Publication No. 62-197335

  However, in the shower head disclosed in Patent Document 1, since the shielding plate is in surface contact with the watering cap, the turning torque for turning the shielding plate by the swirling flow is increased, and the amount of water sprayed and the flow velocity are increased. There was a problem that it was lowered and the massage effect could not be improved. Moreover, since the water sprayed from the water spray hole of the water spray cap is discharged as intermittent shower water, the spray speed of the shower water decreases and the massage effect cannot be improved.

  An object of the present invention is to provide a shower head capable of solving the above-described problems in the prior art and smoothly rotating the impeller and improving the massage effect.

  In order to solve the above problems, the invention according to claim 1 is characterized in that a watering cap having a plurality of watering holes formed in an opening of a water chamber of a main body is joined to a water chamber upstream of the watering cap. The gist is that the impeller is rotatably accommodated by a swirling water flow at a predetermined position, and a gap is formed between the substrate having an opening constituting the impeller and the inner surface of the watering cap.

  The invention according to claim 2 is the invention according to claim 1, wherein a swirling water flow generating member is provided at a predetermined position in the water chamber upstream of the impeller, and a cylindrical portion is provided at an outer peripheral edge of the substrate of the impeller. The gist is that a plurality of blades are provided on the inner peripheral surface of the cylindrical portion.

The gist of the invention of claim 3 is that, in claim 1 or 2, the opening of the impeller is provided on the outer peripheral side of the substrate.
According to a fourth aspect of the present invention, in any one of the first to third aspects, the swirling water flow generating member has a cylindrical portion and a plurality of inclined plates having a fan shape in a plan view provided inside the cylindrical portion. And a plurality of openings formed between opposing edges of each inclined plate.

  A fifth aspect of the present invention is the bearing according to any one of the first to fourth aspects, wherein a shaft portion provided at a central portion of the impeller is rotatably supported at a central portion of the swirling water flow generating member. The center part of the impeller substrate is formed with a convex part or a concave part that is engaged with the concave part or the convex part formed in the central part of the inner surface of the watering cap. .

  The invention according to claim 6 is characterized in that, in claim 4 or 5, the opening of the swirling water flow generating member is set to an even number or an odd number, and the blades of the impeller are set to an odd number or an even number. And

The gist of a seventh aspect of the present invention is that, in any one of the first to sixth aspects, the water spray hole of the water spray cap is formed in a tapered shape having a smaller diameter toward the tip.
(Function)
In this invention, since a gap is formed between the inner surface of the watering cap and the substrate of the impeller, water is not divided when the impeller is turned and the opening is turned. The amount of the shower water is repeatedly increased and decreased, and it is applied to the body as continuous and strong shower water. As a result, the massage effect is enhanced compared to intermittent pulsed shower water. In addition, the contact area between the watering cap and the impeller substrate is reduced, the contact resistance of both members during the rotation of the impeller is reduced, the impeller can be rotated properly, and shower water is injected. It can be done properly to improve the massage effect.

  According to the present invention, the impeller can be smoothly rotated and the massage effect can be improved.

Further, as shown in FIG. 14B, the openings 17d of the impeller 17 are formed at three locations at equal pitches in the circumferential direction so as to be positioned on the outer peripheral side of the flat plate portion 17b, and the blades The planar shape of 17e may be formed in an arc shape. In these embodiments, since the three openings 17d are formed on the outer peripheral side of the flat plate portion 17b, when the impeller 17 is rotated and each opening 17d is turned, the outer peripheral side of the watering cap 13 is rotated. From the sprinkling hole 13e, the water is ejected vigorously as a cylindrical lattice shower water. As a result, shower water whose water volume changes repeatedly can be properly supplied to the scalp, etc., and scalp massage, shampoo and soap can be effectively washed, and the amount of water used is reduced to save energy. can do. Furthermore, when shower water is applied to the face, dirt such as makeup on the face can be effectively removed, and the massage effect can be enhanced.
