Furthermore, the tips of the two leg portions 48b of the portal spring 48 extending into the portal spring holding member 50 are received in the heart cam grooves 56c formed on both side surfaces of the cylindrical portion 56a, respectively. ing.

  The first slide pin 30 is a substantially cylindrical member, and one end of the first slide pin 30 is connected to the tip of the slide shaft 52. Further, the other end of the first slide pin 30 is disposed so as to press the end surface of the slide box 20 on the front end side (left side in FIG. 3). The first slide pin 30 is slidably received in the cylindrical portion 56a of the heart cam member 56, and the first position (FIG. 4) where the first water passage hole 26a is closed and the second water passage. The hole 26b is slid between a second position (FIG. 3) where the hole 26b is closed.

  First, as shown in FIG. 4, when the first slide pin 30 is in the first position, the tips of the leg portions 48b of the portal spring 48 are located near the point P1 of the heart cam groove 56c. In this state, the operation unit 8, the operation unit main body 46, and the portal spring holding member 50 are moved to the distal end side (left side in FIG. 4) by the urging force of the operation unit urging spring 54. Thereby, the slide shaft 52 and the first slide pin 30 attached thereto are also moved to the first position on the distal end side.

  Next, when the operation unit 8 is pressed toward the base end side (right side in FIG. 4) by the user's operation, the portal spring holding member 50 is moved against the urging force of the operation unit urging spring 54. Moved to the end side. As a result, the portal spring 48 attached to the portal spring holding member 50 is also moved to the proximal side, and accordingly, the distal end of the leg portion 48b of the portal spring 48 is proximal to the inside of the heart cam groove 56c. Moved to.

  When the pressing operation of the user is finished and no pressing force is applied to the operation unit 8, the operation unit 8, the operation unit main body 46, and the portal spring holding member 50 are moved to the distal end side by the urging force of the operation unit urging spring 54. Start moving to. At this time, the tip of the leg 48b of the portal spring 48 disposed in the heart cam groove 56c is moved to the point P2 of the heart cam groove 56c, and the tip of the leg 48b is held at this position. As a result, the operation unit 8, the operation unit main body 46, and the portal spring holding member 50 are held at the second position shown in FIG. 3 against the urging force of the operation unit urging spring 54.

  As the operation unit 8 moves to the second position, the first slide pin 30 attached to the distal end of the slide shaft 52 is also moved to the proximal side (right side in FIG. 4), and the slide box 20 is moved to the position shown in FIG. To the second position shown in FIG. In the present embodiment, the first slide pin 30 is moved about 4 mm along the movement axis A between the first position shown in FIG. 4 and the second position shown in FIG.

  Further, when the user presses the operation unit 8 again, the operation unit 8 is slightly moved from the position shown in FIG. 3 to the base end side (right side in FIG. 3). By this movement, the tip of the leg portion 48b held at the point P2 of the heart cam groove 56c is disengaged from the position, and the engagement with the heart cam groove 56c is released. Next, when the pressing force on the operation unit 8 by the user does not act, the operation unit 8, the operation unit main body 46 and the portal spring holding member 50 are moved to the distal end side by the urging force of the operation unit urging spring 54. , Moved to the first position shown in FIG.

  Thus, when the first slide pin 30 is moved from the first position shown in FIG. 4 to the second position shown in FIG. 3 by the first slide pin moving mechanism 36, the slide box 20 is moved to the first slide pin 30. And is moved to the base end side (right direction in FIG. 4). When the slide box 20 is moved to the base end side, the second slide pin 32 is also moved to the base end side against the biasing force of the second slide pin biasing spring 34. On the other hand, when the first slide pin 30 is moved from the second position shown in FIG. 3 to the first position shown in FIG. 4 by the first slide pin moving mechanism 36, the biasing force of the second slide pin biasing spring 34 is used. The second slide pin 32 presses the slide box 20 toward the distal end side (left direction in FIG. 3). Thereby, the slide box 20 is moved to the front end side and is moved to the first position shown in FIG. Therefore, in the present embodiment, the first slide pin moving mechanism 36, the first slide pin 30, the second slide pin 32, and the second slide pin biasing spring 34 are the slide box 20 and the first and second spherical valve bodies. It functions as a valve body moving mechanism to be moved.

Next, the effect | action of the water discharging apparatus 1 by embodiment of this invention is demonstrated.
First, when the hot water / mixing tap 4 (FIG. 1) is operated to discharge water, the hot water that has passed through the hot / water mixing tap 4 flows into the shower hose 14 (FIG. 3) connected to the head portion 1a. The hot water flowing out from the shower hose 14 flows into the recess 6a of the head body 6 and further flows into the valve body box 26d of the base member 26.

  When the head portion 1a is in the second position shown in FIG. 3, the second spherical valve body 18 is located above the second water passage hole 26b. For this reason, the second coil spring 24 disposed in the valve body receiving portion 20b of the slide box 20 presses the second spherical valve body 18 against the upper end opening of the packing 28b. That is, the second coil spring 24 causes the second spherical valve body 18 to be seated on the second valve seat, thereby closing the second valve seat. On the other hand, in the second position, the first spherical valve body 16 is not aligned with the packing 28a, and the first spherical valve body 16 is separated from the first valve seat, so the first valve seat is open. . Thereby, the hot water which flowed into the inside of the valve body box 26d is discharged from the rectification water discharge part 10 through the packing 28a and the 1st water flow hole 26a.

  Next, when the user presses the operation unit 8, the first slide pin moving mechanism 36 moves the first slide pin 30 to the first position shown in FIG. 4. As a result, the slide box 20 is pressed toward the distal end side (left direction in FIG. 3) by the second slide pin 32 and moved to the first position. At this time, the second spherical valve element 18 seated on the second valve seat is moved upward while being pushed up against the urging force of the second coil spring 24 and is separated from the second valve seat. . As described above, when the spherical valve body is separated from the valve seat, the spherical valve body is moved in the horizontal direction and the vertical direction. Therefore, a large flow path can be obtained simply by moving the spherical valve body in the horizontal direction with a short stroke. Area is secured.

  On the other hand, the first spherical valve body 16 that has been separated from the first valve seat is moved to a position aligned with the packing 28 a, and the first spherical valve body 16 is placed in the valve body receiving portion 20 a of the slide box 20. The first coil spring 22 is pressed against the upper end opening of the packing 28a. That is, the first coil spring 22 causes the first spherical valve body 16 to be seated on the first valve seat, thereby closing the first valve seat. Thereby, the flow path is switched so that the hot water flowing into the inside of the valve body box 26d is discharged from the shower water discharger 12 through the packing 28b and the second water passage hole 26b.

  According to the water discharging apparatus of the embodiment of the present invention, the first valve seat is opened and closed by the first spherical valve body, and the second valve seat is opened and closed by the second spherical valve body. The moving distance of the spherical valve body and the second spherical valve body can be designed independently of the distance between the first valve seat and the second valve seat. Thereby, since the movement distance of a 1st spherical valve body and a 2nd spherical valve body can be designed short, a water discharge state can be switched rapidly. Further, since the stroke for operating the operation unit can be designed to be short, the operational feeling can be improved.

  Further, according to the water discharge device of the present embodiment, the first spherical valve body and the second spherical valve body are seated on the first valve seat and the second valve seat by the first coil spring and the second coil spring, respectively. The first valve seat and the second valve seat can be reliably closed.

  Furthermore, according to the water discharge device of the present embodiment, the first spherical valve body and the second spherical valve body are moved by the slide box while maintaining the distance between them. The two spherical valve bodies can be simultaneously moved by the same distance.

  Moreover, according to the water discharging apparatus of this embodiment, since the moving distance of the 1st spherical valve body and the 2nd spherical valve body is very shorter than the valve seat space | interval and shorter than the radius of each spherical valve body, it is short operation. The stroke can quickly switch between rectified water discharge and shower water discharge.

  Furthermore, according to the water discharge device of the present embodiment, since the distance between the valve bodies is shorter than the valve seat interval, the spherical valve body that is separated from the valve seat is always located between the valve seat and the valve seat.
