It is a principal part expanded sectional block diagram of the watering hole lower part of FIG. It is a principal part expanded sectional block diagram of FIG.

Next, the form for implementing this invention is demonstrated using an Example.
FIG. 1 is an external perspective configuration diagram of a state in which the shower head 1 is hooked on a shower hanger 13, and FIG. 4 is a cross-sectional configuration diagram illustrating an internal structure of the shower head. 2 and 3 are exploded perspective views of the constituent members of the shower head viewed from different directions.

  The shower head 1 is a rod-shaped shower head main body 2 having a connecting portion 2a of a shower hose 9 at the lower end, and a tubular shape that is inserted into the shower head main body 2 from above and is externally fitted to the shower head main body 2. The cover 6 and the cap 7 screwed to the upper end of the shower head main body 2 are mainly configured.

  The shower head main body 2 is made of resin, and a locking portion 2b is formed in a ring shape protruding in the radial direction above the shower hose connection portion 2a on the lower end side. A projecting portion 2c extending in the vertical direction upward from the locking portion 2b is integrally formed so as to project in the radial direction, and the upper end of the projecting portion 2c is an upper end projecting portion 2d that projects further in the radial direction.

Inside the shower head body 2, a supply path 3 through which water is introduced from the shower hose 9 is formed so as to penetrate from the lower end to the upper end side.
A tubular water spray plate member 4 is attached to the outer periphery above the upper end protrusion 2d of the shower head body 2 through an O-ring 8 in the form of a cover, as shown in FIG. In addition, a plurality of claws 2f, 2f formed to protrude above the upper end projection 2d of the shower head body 2 are fitted into a plurality of openings 4c, 4c formed on the lower end side of the water spray plate member 4, respectively. The water spray plate member 4 is integrally covered on the outer periphery of the upper portion of the shower head body 2.

  A partition wall 2e of the shower head main body 2 extends in the water spray plate member 4 from below to above, and inside the water spray plate member 4 by the partition wall 2e, the inner supply passage side partition portion 3a and the outer water spray hole side. The supply passage side partition portion 3 a is continuous with the supply passage 3. The outside position of the water spray hole side partition part 3b of the water spray plate member 4 is a water spray plate part 4b in which a large number of water spray holes 5, 5, and 5 are formed, and is located behind the upper surface 4a at the upper end of the water spray plate member 4. On the side, a concave portion 4d is formed integrally in a V-shape downward, and a male screw is formed on the outer periphery of the upper end of the water spray plate member 4 to form a mounting portion 4f of the cap 7. .

  The supply channel side partition portion 3a and the water spray hole side partition portion 3b partitioned by the partition wall 2e are communicated with each other through a communication passage 3c at the upper end thereof. Since it is formed in the gap between 4a and the recess 4d is formed, the flow path at the upper end of the supply path side partition part 3a is narrowed.

  The cover 6 fitted around the outer periphery of the shower head main body 2 and the water spray plate member 4 is made of mirror-finished metal and is formed in a straight cylindrical shape having an upper end opening 6a and a lower end opening 6b. On the back side, a notch 6c is formed in a slit shape upward from the lower end opening 6b. A large number of openings 6d, 6d, 6d are formed through the upper portion of the front side of the cover 6 opposite to the notch 6c. The number of the many openings 6d is the same as the number of the many water holes 5 formed in the water spray plate portion 4b, and the positions of the respective openings 6d are formed at the same positions as the positions of the water holes 5. Is.

That is, as shown in the enlarged cross-sectional view of the main part of FIG. 5, in the state in which the cover 6 is fitted, the water spray holes 5 of the water spray plate part 4b and the openings 6d of the cover 6 are aligned.
6 is an enlarged cross-sectional view of the vicinity of the water sprinkling hole 5 in a state in which the cover is externally fitted. In the center of FIG. 6, the supply passage side partition portion 3a continuous with the supply passage 3 described above is formed. The water spray hole side partition part 3b is formed outside through the partition wall 2e, and the water spray plate part 4b having a large number of water spray holes 5 is arranged outside the water spray hole side partition part 3b. The

  On the outer periphery of the upper portion of the shower head main body 2, a water spray plate member 4 is preliminarily covered integrally with claws 2f and 2f. In this state, the cover 6 is covered with the water spray plate member 4 and the shower head main body from the upper end side. When the projection 2c on the shower head body 2 side is inserted into the notch 6c of the cover 6 and the cover 6 is further moved downward, Eventually, the lower end opening 6b of the cover 6 comes into contact with the upper surface of the ring-shaped locking portion 2b of the shower head body 2. In this state, the cap 7 is screwed into the mounting portion 4f on the outer periphery of the upper end of the water spray plate member 4 from above, and when the cap 7 is tightened, the lower end of the cap 7 comes into contact with the upper end opening 6a of the cover 6, Thus, the cover 6 is sandwiched and fixed between the locking portion 2b of the shower head body 2 and the cap 7.

  When the cover 6 is attached, the protrusion 2c is inserted into the notch 6c so that the cover 6 is well guided and assembled, and the cover 6 is positioned well without rotating and the shower head main body. 2 and the outer periphery of the water spray plate member 4, and the water spray hole 5 of the water spray plate member 4 and the opening 6d of the cover 6 are attached in a well aligned state. That is, each opening 6d is reliably arranged outside each watering hole 5.

  In the state where the cover 6 is completely attached, as shown in FIG. 4, the protrusion 2 c and the upper end protrusion 2 d protrude outward from the notch 6 c and protrude outside the cover 6. Accordingly, when the shower head 1 is used, when the grip portion 6P in the lower part of the cover 6 is gripped by the hand, the protrusion 2c hits the hand, and thereby the user can grip the shower head 1 firmly. Moreover, the direction of the water spray hole 5 and the opening 6d on the opposite side can be well known by the protrusion 2c, and the shower head 1 is easy to use without making a mistake in the water spray direction.

Thus, since the protrusion 2c protrudes to the outer peripheral side of the cover 6, when it is grasped by a hand, it becomes a slip stopper in the rotation direction, and further protrudes to the upper end side of the protrusion 2c to form an upper end protrusion 2d. Therefore, the upper end protrusion 2d provides an anti-slip action in the vertical direction, and when it is used while being gripped with a hand, the vertical slip is also suppressed, which makes it easy to use.
In FIG. 4, the cap nut 12 at the tip of the shower hose 9 is screwed to the outer periphery of the shower hose connection portion 2a at the lower end, and the shower hose 9 is connected to the shower hose connection portion 2a. An O-ring 10 and a U-packing 11 are interposed on the inner periphery of the cap nut 12 to ensure sealing performance.

  In the shower head 1 having such a structure, hot water is introduced into the supply path 3 from the shower hose 9 side, and hot water is further introduced from the supply path side partition part 3a through the communication path 3c to the sprinkling hole side partition part 3b. Shower water is ejected from a large number of water spray holes 5 through a large number of openings 6b.

When the shower is stopped (after use), the water remaining in the water spray hole partition 3b and the communication passage 3c is discharged well from the water spray hole 5 and the opening 6d, and the water spray hole partition 3b. In addition, since the volume of the communication passage 3c is small, the amount of water discharged is small, and the remaining water can be discharged quickly when the shower is stopped.
Moreover, the water spray hole 5a on the lowermost side of the large number of water spray holes 5 is formed in a large diameter as shown in the enlarged cross-sectional view of the main part in FIG. 7, and is configured so that the remaining water can be drained earlier.

  As shown in the enlarged cross-sectional view of the main part in FIG. 8, ribs 4 e that protrude in the radial direction and come into contact with the inner periphery of the cover 6 are provided on the outer periphery of the water spray plate member 4 below the water spray hole 5 a on the lowermost end side. The rib 4 e prevents the water from entering the cover 6 and prevents the water from dripping from the lower end of the cover 6.

In addition, since the upper end side of the supply path side partition part 3a is a very narrow passage by the recess 4d, the amount of water discharged after the shower is stopped (after use) can be reduced, and the remaining water can be quickly discharged. Can be discharged to the outside.
After the shower is stopped (after use), the water discharged from the large number of water spray holes 5 and the cover opening 6d flows down the straight outer peripheral surface of the cover 6 at an early stage, and falls down quickly. The discharge rate of the remaining water to the side is increased, the dripping water does not droop from the opening 6d, and the remaining water is discharged at an early stage in an inconspicuous state.
In addition, the shower head 1 having such a structure can be removed by pulling the cover 6 upward from the shower head body 2 by removing the cap 7, whereby cleaning around the sprinkling holes 5 and the like can be performed very easily. Will be able to.

  It should be noted that calcium contained in the water may crystallize and adhere to the outer end of each sprinkling hole 5 and the inner peripheral side of each opening 6d shown in FIG. If a deposit (scale) such as a crystal is attached, the cap 7 is removed, and the cover 6 is moved up and down on the outer periphery of the shower head main body 2 to adhere to the water sprinkling hole 5 and the opening 6d. The removed scale can be removed well, and then the scale can be removed by washing with water, which makes cleaning easy.
