In addition, it is possible to appropriately select a watertight connection method such as interposing an elastic member such as an O-ring or simply sealing with a resin seal.

  In order to assemble the watering head, the screw 29 and the watering member 3 connected to the rotating member 2 are pivotally supported on the shaft member 18 protruding from the water passing head portion 6 of the head body 1. Is screwed into the shaft member 18 through the screw hole 28 and the shaft through hole 22 (FIG. 1).

Hereinafter, the operation of switching the watering state of such a watering head will be described.
In a state where the fan water hole 25c is in communication with the outlet 7a, the water supplied from the inner water hole 7 of the head body 1 passes through the fan water hole 25c and the water spray pipe 36b from the outlet 7a. It discharges from the fan water spout 33 (refer FIG. 2).

When the rotary member 2 is rotated counterclockwise from the fan water discharge position and the shower water passage hole 25b is communicated with the outlet 7a as shown in FIG. 6, the internal water passage hole 7 of the head body 1 is used. From the outlet 7a passes through the shower water hole 25b and flows into the gap between the water spray plate 3a. The water flowing into the gap passes through the flow path indicated by the broken arrow in FIG. 5C and is discharged from the shower sprinkling port 31 with a relatively strong water force.
At this time, since the closing portion 16a is positioned and closed upstream of the sprinkle water hole 25d, water does not flow from the gap to the sprinkle water hole 25d and cause water leakage.

  In a state where the rotating member 2 is further rotated counterclockwise from the shower water discharge position and the straight water hole 25a is communicated with the outlet 7a, the water supplied from the internal water hole 7 of the head body 1 is used. Is discharged from the straight water spout 32 through the straight water hole 25a and the water spray tube 36a from the outlet 7a.

In the state where the rotating member is rotated clockwise from the water discharge position and the water outlet hole 25d is in communication with the outlet 7a as shown in FIG. 7, the water is supplied from the internal water hole 7 of the head body 1. The water to be passed flows from the outlet 7a through the sprinkle hole 25d into the gap between the water spray plate 3a. The water that has flowed into the gap passes through the flow path indicated by the broken line arrow in FIG.
Since the water passage hole 25d has a smaller diameter than the shower water hole 25b, the flow rate of water flowing into the gap from the internal water hole 7 is reduced. Therefore, water is discharged from the shower spout 31 in a shower water discharge state (joro water discharge state) with relatively weak water.
At this time, since the closing portion 16b is positioned and closed upstream of the shower water passage hole 25b, water does not flow from the gap to the shower water hole and cause water leakage.

  In the state where the rotating member 2 is further rotated clockwise from the sprinkling water discharge position and the cone water hole 25e is communicated with the outlet 7a, the water supplied from the internal water hole 7 of the head body 1 is From the outlet 7a, it passes through the cone water hole 25e and the water spray cylinder 36c, and is discharged from the cone water spout 34 (see FIG. 2).

  In such a watering head, by rotating the watering member 3 and the rotating member 2, one of the shower water hole 25b and the water hole 25d having different diameters is selected and communicated with the outlet 7a. Since water is sprinkled from the shower sprinkling port 31 and the other is closed by the front end surface of the water flow head unit 6, a flow control device that is easy to switch with a compact configuration is provided. Moreover, since many water flow holes 25a-25e are arrange | positioned on the same periphery of the rotation member 2, many water flow holes can be provided also in the thin disk-shaped rotation member 2, and flow volume is provided. The control device can be reduced in size.

  In particular, a gap is provided between the tip of the shower water hole 25b and the water sprinkle hole 25d and the water spray plate 3a of the water spray member 3, and this is used as a common water flow path to the shower water spout 31. Compared with the case where a water channel is provided, it is possible to save materials and manufacture parts easily.

Further, when one of the shower water passage hole 25b and the sprinkle water passage hole 25d communicates with the outflow port 7a, the other is closed by the closing portion 16, and thus water leakage is prevented.
By sealing the closing portion 16 in a watertight manner with the O-ring 20 having a necessary minimum area, it is possible to minimize the resistance of the rotating operation caused by the sealing member such as the O-ring, and to control the flow rate easily. An apparatus is provided.

  Further, on the same circumference as the shower water hole 25b and the Jolo water hole 25d, the straight water hole 25a that communicates with the straight water hole 32, the fan water hole 33, and the cone water hole 34 independently of each other. By providing the fan water hole 25c and the cone water hole 25e, it is possible to switch the water discharge shape in addition to the flow rate control by the turning operation in the same plane.
