Description

  The present invention relates to a sealing structure for a shower nozzle used as a bathroom water discharger or the like.

In the case of a conventional shower nozzle, when the shower nozzle is locked to the shower hook after use, the water staying in the shower nozzle that has stopped due to the balance of the surface tension falls from the shower nozzle sprinkling part forever. , There was something inferior.
On the other hand, in order to solve the conventional problems and provide a shower nozzle with good water drainage as disclosed in Patent Document 1, a mesh-like net is already disclosed inside the watering part. . In this case, in order to make it difficult for water droplets falling from the shower nozzle to fall forever, a solution is achieved by incorporating a mesh-like net and increasing the surface tension.

JP 2002-355581

However, even when a mesh-like net is inserted inside the sprinkling part, the surface tension of the net part breaks if the shower head touches the shower hose or the like and gives vibration during cleaning. Air exchange began, and the water staying in the shower nozzle fell forever and the quality was poor.
In particular, in a substantially columnar shower nozzle, the water head pressure inside the sprinkling portion is entirely applied to the downstream water passage holes, so that residual water tends to hardly stop.
In addition, a mesh-like net for exerting a strong surface tension has a problem in that it is expensive to perform special processing and the cost of parts is increased.

Accordingly, the object of the present invention is to solve the above-mentioned problems and to seal the shower nozzle with good water drainage so that the remaining water remaining in the shower head does not leak even when it touches the shower hose during cleaning or the like and is subjected to vibration. It is to provide a stop structure.

In order to solve the above-described problem, in claim 1, a shower nozzle including a hot water inlet, a shower head body having a water passage communicating from the hot water inlet, and a watering portion having a plurality of water holes is provided. In
A sealing structure for a shower nozzle, wherein the water spray portion is provided with a closing member that closes the water passage hole in the closed state and expands the water passage by water pressure in the water passage state to open the water passage hole and sprinkle water. It was.

  By configuring in this way, after the use of the shower is over, the water passage hole can be closed with the closing member mounted inside the watering part, so that the remaining water staying in the shower nozzle is cleaned, etc. At this time, even when the shower hose is touched and vibrations are applied, air exchange is not performed, and it is possible to provide a shower nozzle with good water drainage by preventing leakage.

  In order to solve the above-described problem, in claim 2, the closing member is a soft body that can expand and contract.

  By configuring in this way, after the use of the shower is over, the water passage hole can be closed with a stretchable soft body mounted inside the water sprinkling unit, so that the remaining water staying in the shower nozzle is retained. When cleaning, a shower hose or the like is touched and vibrations are applied, so that the air is not exchanged, so that it can be prevented from leaking and the shower nozzle with good water drainage can be provided.

  In order to solve the above problems, in claim 3, the water passage in the shower head body is closed by the closing member via an elastic member.

  Thereby, since a water flow path can be obstruct | occluded with an elastic member with the pressing force of an elastic member, the water leak from a shower head can be prevented reliably after water stop.

  In order to solve the above problem, in claim 4, the elastic member is a spring member.

Thereby, since the water passage of the shower head can be closed with an elastic member with a simple structure, the cost is reduced and the cost is not increased.

  According to the present invention, there is an effect that the residual water staying in the shower nozzle is not leaked even if the shower hose is touched and vibrations are applied during cleaning.

In order to further clarify the configuration and operation of the present invention described above, preferred embodiments of the present invention will be described below.
FIG. 1 is an external perspective view of a shower nozzle according to an embodiment of the present invention. FIG. 2 is a longitudinal sectional view of a shower nozzle according to an embodiment of the present invention.

First, the appearance of the shower nozzle 1 will be described with reference to FIG.
The shower nozzle 1 has an I-shaped substantially cylindrical shape.
And the shower nozzle 1 is provided with the shower head main body 2 with a hand, and the watering part 1a which formed the several water flow hole 3 in the side surface.
A shower hose (not shown) is connected to one end of the shower nozzle 1 via a joint 11. A cap 7 is disposed on the other end.

Next, the internal structure of the shower nozzle 1 will be described with reference to FIG.
The shower nozzle 1 of the present invention is mainly composed of a shower head main body 2 having a hot water inflow port 2a, a water spray pipe 4 having a plurality of water passage holes 3, and a soft body 8 which is a stretchable closing member. ing.

The specific structure of each component and the mutual relationship of each component will be described below.
The shower head main body 2 has an I-shaped substantially cylindrical shape.
One end of the shower head body 2 is provided with a hot water inlet 2a to which hot water is supplied from a water tap (not shown) via a shower hose (not shown), and the other end has an O-ring. And a screw part 5 to which the water spray pipe 4 is screwed through a packing 9 such as the above.
That is, the shower head main body 2 and the water sprinkling pipe 4 are integrally connected via the screw part 5, and the shower nozzle 1 forms an I-shaped substantially cylindrical shape.

  The water spray pipe 4 has an I-shaped substantially cylindrical shape, forms a water sprinkling part 1a on the side surface, and a plurality of water passage holes 3 are provided in the longitudinal direction of the side surface of the water sprinkling pipe 4 (water sprinkling part 1a). Yes.

A flexible soft body 8 is mounted inside the water spray pipe 4.
The soft body 8 is made of a stretchable material such as a stretch material, or a flexible rubber material, and has cylindrical portions 8a used at the ends of the soft body 8 when attached to a water spray pipe (FIG. 7). reference).

  A shaft 10 for fixing the cylindrical portion 8 a provided at both ends of the soft body 8 to the water spray pipe 4 is inserted. One of the soft bodies 8 into which the shaft 10 is inserted is inserted into a first notch 18 provided at one end of the water spray pipe 4. The first notch 18 is provided along the shape of the water spray pipe 4 from above the water passage hole 3. Thereafter, a cap 7 having a packing 6 such as an O-ring is screwed to the water spray tube 4 and fixed. Thereby, even if it is a case where the water pressure from an upstream side is received, the cap 7 is being fixed without removing. The shaft 10 at the other end is inserted and fixed in a second notch 19 provided in an L-shape on the inner wall of the threaded portion 5 of the water spray pipe 4. Thereby, even if it is a case where the water pressure from an upstream side is received, it is fixed without coming off.

FIG. 3 is a longitudinal sectional view showing a watering state of the shower nozzle 1 according to the embodiment of the present invention. The watering state of the shower nozzle 1 will be described with reference to FIG.
Normally, the hot water supplied from the hot water inlet 2 a enters the space between the sprinkling pipe 4 and the soft body 8 and fills the water hole 3 while spreading the soft body 8. Water can be discharged as a shower. On the other hand, when the supply from the hot water inlet 2a is lost, as the hot water filled in the back surface is lowered by gravity, the hot water also flows out from the water passage hole 3, and the soft body 8 is restored and the water passage hole 3 is restored. And close shower water discharge.

  Thus, the water exchange hole 3 is blocked by the soft body 8, so that the air cannot be exchanged. In other words, even if the surface tension is likely to be broken by vibration, the air cannot be exchanged from the water passage hole 3, so that the stagnant water and the hot water will never leak after use.

FIG. 4 is a longitudinal sectional view showing a water stop state of a shower nozzle according to another embodiment of the present invention.
A lightweight plate 12 can be used to close the water passage hole 3. In this lightweight plate 12, a through hole 14 through which the rotary shaft 15 passes is located in the short direction of the water spray pipe 4, and the other end is bent in parallel to the through hole 14. A rotating shaft 15 is inserted into the through hole 14 and fixed to the upper notch of the water spray pipe 4. The back surface is urged by an elastic body 13 such as a spring in a direction to close the water passage hole 3.

FIG. 5 is a longitudinal sectional view showing a water spray state of a shower nozzle according to another embodiment of the present invention.
In this embodiment, the light-weight plate 12 is configured so as to be inclined toward the center of the water passage portion. With this configuration, the hot water supplied from the hot water inlet 2 a pushes up the lightweight plate 12 against the urging force of the elastic body 13, and the hot water is discharged from the water passage 3 as a shower. On the other hand, when the supply from the hot water inlet 2a is lost, the lightweight plate 12 is pushed to the water hole 3 side by the restoring force of the elastic body 13, the water hole 3 is closed, and the shower water discharge is closed.
It should be noted that even if there is a slight gap between the water passage hole 3 closed by the restoring force of the elastic body 13 and the lightweight plate 12, water does not drip as long as the air is not exchanged. It goes without saying.

Furthermore, FIG. 6 is sectional drawing which shows the water stop and watering state of the shower nozzle 1 which is another Example of this invention.
When the sealing structure of the present invention is applied to a general shower nozzle 1, the soft body 8 is supported by the pressing force of the spring 17 so as to close the water passage 16, and the water stop state is maintained (FIG. 6 (a)).
Moreover, since the soft body 8 is stronger than the pressing force of the spring 17 due to the water pressure of the hot water during watering, shower water is discharged by opening the water passage 16 (see FIG. 6B).
When the water is stopped, similarly to the above effect, the soft body 8 closes the water passage 16 so that water leakage can be surely prevented.

  There is a possibility of being used for a shower device that sprays supplied hot water using a plurality of water holes, for example, a bathroom water discharge device, a kitchen water discharge device, or the like.
