4 to 7 specifically show the configuration of the first pulse shower mechanism 91.
As shown in FIGS. 5, 2, and 7, the first pulse shower mechanism 91 has an annular and circular guide groove 93 provided on the upper surface of the cap 48, that is, the upper surface (inner surface) of the water spray plate 58. ing.
First shower holes 94 are provided at regular intervals in the circumferential direction along the bottom of the guide groove 93.
Here, the first shower hole 94 has a large diameter of φ1.8 mm.
In the present embodiment, a total of eight first shower holes 94 are provided at regular intervals in the circumferential direction.

As shown in FIG. 5, the first pulse shower mechanism 91 further includes a rotating body 96 and a water flow ejection member 98 (both of which are made of resin).
The rotating body 96 is a member having a circular ring shape, and has a bottom portion 100 and a peripheral wall portion 102 as shown in FIG. 6B. Has a ball holding portion 104.
Further, between the ball holding portions 104 and 104, a plurality of walls 106 having an L shape in plan view are provided at equal intervals.
Here, the wall 106 has a main portion 106A extending in the center direction, that is, in the centripetal direction from the annular peripheral wall portion 102, and a bent portion 106C bent at a right angle at the tip of the main portion 106A.

The rotating body 96 is provided with a plurality of slit-shaped through-openings 108 at a constant pitch on the bottom 100, and a side opening 110 is formed between adjacent L-shaped walls 106 and 106 in plan view. Has been.
The ball holding portion 104 in the rotating body 96 has a holding hole 112 (see FIG. 6B) having a spherical shape opened on the lower surface in the drawing, strictly speaking, a partial spherical shape. The balls 114 (the balls 114 are also made of resin) are rotatably held in a state where their lower portions protrude slightly downward.

The rotating body 96 is configured such that a ball 114 having a lower portion projecting from each holding hole 112 is concavo-convexly fitted in the guide groove 93 having a concave shape with a circular cross-sectional shape, and the concavo-convex fitting state is maintained. The ball 114 rotates around the center of the guide groove 93 (the center in the radial direction) while rotating around the guide groove 93.
In other words, the guide groove 93 and the ball 114 are rotated along a rotation locus defined by the concave-convex fitting.

At this time, when the ball 114 that rolls along the guide groove 93 reaches the shower hole 94 provided at the bottom of the guide groove 93, the shower hole 94 is blocked by the ball 114, and this is further separated into the ball. The shower hole 94 is opened by 114 passing.
That is, each ball 114 intermittently blocks and opens each shower hole 94 as it moves around the guide groove 93.

On the other hand, the water jet member 98 has a disk shape as a whole, and has a plurality of jet holes 116 at a constant pitch along the circumferential direction.
Each injection hole 116 forms an oblique hole, and the water flowing from the upstream side passes through the injection hole 116 to the downstream side, and at this time, the above-mentioned wall provided in the rotating body 96 as the injection water flow. A driving force for rotating the rotating body 96 is generated by colliding with 106.

In the present embodiment, the first pulse shower mechanism 91 operates as follows.
By rotating the ring-shaped switching operation portion 64, the water that has flowed into the first water channel 74 by matching the first inflow opening 82 shown in FIG. It reaches the upper surface of the water jet member 98 downward in the figure via 88.
The water flow injection member 98 injects the water that has reached in this way as a water flow through its own injection hole 116 downward in the figure and obliquely in the rotational direction.
The jet water flow hits the wall 106 of the rotating body 96 to rotate it.

At this time, the rotating body 96 rotates smoothly along the rotation locus defined based on the concave / convex fitting between the ball 114 and the guide groove 93 and by the function of the ball 114 as a bearing.
At that time, the ball 114 rolls (rotates) the guide groove 93 integrally with the rotating body 96 while being held by the rotating body 96, and the ball 114 is moved along with the rotating motion, that is, every time it passes through the first shower hole 94. It shuts off and opens, so that the shower water is intermittently discharged from the first shower hole 94 to discharge the pulse shower.

  In other words, in this embodiment, the ball 114 cooperates with the guide groove 93 to define the rotation locus of the rotating body 96, to reduce the rotational resistance of the rotating body 96 as much as possible by the bearing action, Three functions as a valve for opening and closing one shower hole 94 are simultaneously performed.

  In the first pulse shower mechanism 91, the first shower holes 94 are large-diameter shower holes with a large hole diameter, and the first shower holes 94 as a whole have a small number of only eight and a large pitch. Therefore, a thick and vigorous water flow is jetted from each first shower hole 94. Therefore, the shower water flow from the first shower hole 94 is effectively interrupted, and the user is effectively massaged. Is done.

4, 5 and 8 show the configuration of the second pulse shower mechanism 92 in detail.
As shown in FIG. 5, the second pulse shower mechanism 92 has second shower holes 118 arranged in a triple concentric manner on the inner peripheral side of the first shower hole 94. ing.
The outermost shower hole 118-1, the inner shower hole 118-2, the innermost shower hole 118-3, and the innermost shower hole 118-3 have the same diameter of 0.8 mm at the tip (lower end). However, the diameter of the opening at the upper end is gradually reduced from the outermost shower hole 118-1 to the inner peripheral shower hole 118-2 and further to the innermost shower hole 118-3. .

  In addition to the second shower hole 118 described above, the second pulse shower mechanism 92 includes a cylindrical hollow shaft 120 that rises from the center of the water spray plate 58 and a cylindrical shape that is rotatably fitted to the shaft 120. An impeller 124 having a fitting portion 122 and a water jet member 127 having a solid shaft 126 fitted further downward in the figure inside the cylindrical shaft 120 are provided.

The water jet member 127 has a disk shape, and is press-fitted into the press-fitting hole 125 of the lower case 20 at the outer peripheral portion and fixed thereto.
The water jet member 127 introduces the water flowing in through the inflow opening 84 of FIG. 3 (a) and the communication opening 90 of FIG. Then, a jet water flow is generated, and this is applied to the blade 129 of the lower impeller 124 in the figure to generate the rotational driving force of the impeller 124.
Here, as shown in FIG. 8, the direction of the injection hole 128 is determined so that the water flow injected from here hits the concave side of the curved blade 129 of the impeller 124.

Each blade 129 of the impeller 124 is extended from the center toward the outer periphery so as to draw a partial spiral shape.
The impeller 124 is based on the fitting of the cylindrical fitting portion 122 to the cylindrical hollow shaft 120 erected from the water spray plate 58, with the shafts 120 and 126 serving as rotation support shafts and the shaft 120 and the middle shaft 120. It rotates around the axis of the real axis 126.
As shown in FIG. 8, the impeller 124 has an approximately half of its lower surface opened and the other approximately half closed, and the closed portion intermittently blocks the second shower hole 118. The shower hole blocking part 130 to be opened is formed.

The second pulse shower mechanism 92 operates as follows.
The water that has flowed into the second water channel 76 of FIG. 2 by matching the inflow opening 84 of FIG. 3 with the outflow opening 80 by the rotation operation of the switching operation unit 64 passes to the water jet member 127 through the communication opening 90 of FIG. It arrives.
The water jet member 127 passes the flowing water through its own injection hole 128, and at that time, the passing water becomes a jet water flow and collides with each blade 129 of the lower impeller 124.
Here, the impeller 124 rotates around the hollow shaft 120 by the momentum of the jet water flow.
At this time, the shower hole blocking part 130 in a state of covering substantially half of the lower surface of the impeller 124 intermittently blocks and opens the second shower hole 118 with rotation, and intermittently shower water from the second shower hole 118. Let the water discharge into the pulse.

The number of the second shower holes 118 is large as a whole, and each shower hole has a smaller diameter than the first shower hole 94 in the first pulse shower mechanism 91. Water is discharged.
And the shower water can achieve water saving by intermittently discharging water and stopping water discharge, that is, intermittent shower water discharge.

  As described above, the first pulse shower mechanism 91 in the shower water spouting device of the present embodiment can rotate the impeller based on the fitting structure of the shaft and the cylindrical portion that is rotatably fitted to the shaft as in the prior art. The ball 114 held rotatably on the rotating body 96 is fitted into the circular guide groove 93 provided on the inner surface of the water spray plate 58, and the ball 114 is held while maintaining the concave and convex fitting state. The rotating body 96 is rotated about the center of the guide groove 93 while rotating 114 along the guide groove 93, and the ball 114 acting as a shower hole blocking portion is accompanied by the rotational movement of the rotating body 96. One shower hole 94 is cut off and opened intermittently.

  Therefore, it is possible to arrange the rotating body 96 at a position on the outer peripheral side of the water spray plate 58, and intermittently discharge the shower water from the shower hole 94 at the position on the outer peripheral side of the water spray plate 58 for massage. be able to.

In some cases, the second shower holes 118 in the second pulse shower mechanism 92 are made large shower holes, and the number thereof is reduced. It is also possible to configure as a massage pulse shower mechanism, or the second pulse shower mechanism 92 is omitted and the first pulse shower mechanism 91 is positioned at the center side of the water spray plate 58, i.e., inside. It is also possible to arrange them on the circumferential side.

Further, in some cases, the first pulse shower mechanism 91 can be configured to discharge normal shower water by reducing the diameter of the shower holes 94 and increasing the number thereof.
Further, in the above embodiment, the ball 114 in the first pulse shower mechanism 91 is configured as a shower hole blocking portion that blocks and opens the first shower hole 94 intermittently. It is also possible to provide other than the above.
