Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a nozzle for a private parts cleaning device.

(Prior art) Conventionally, water pressure using a pump device installed inside the container,
Alternatively, in a hydraulic telescopic nozzle device that moves the nozzle 1 for body washing using direct tap water pressure, in order to prevent the surface of the nozzle 1 from getting dirty and the discharge hole 1a to be clogged after use, a part of the nozzle 1 is A hydraulic telescopic self-cleaning nozzle is used in which dirt is washed from the nozzle 1 by flowing water through the gap between the nozzle 1 and the cylinder 2, and after the extension of the nozzle 1 is completed, this gap is sealed with a packing 4.

(Problem to be solved by the invention) However, for example, if a sudden valve opening operation is performed, the water seal packing 4 provided in the nozzle 1 will violently collide with the inner wall of the cylinder 2, causing deterioration of the packing 4 and causing water leakage. It was causing this.

Also, depending on the quality of the water used, water scale may adhere to the discharge hole 1a and the outer periphery of the nozzle 1, causing malfunctions in the expansion and contraction of the nozzle 1. In this case, the nozzle 1
If the gap between cylinder 2 and cylinder 2 is increased, nozzle 1
It has been difficult to enlarge the gap because the water pressure when the extension is completed becomes high, and the water pressure discharged from the nozzle 1 also becomes high, causing strong contact with the private parts and making it unusable.

The present invention aims to solve the above-mentioned problems and provide a hydraulic telescopic self-cleaning nozzle that is extremely reliable, provides a soft cleaning sensation, and is easy to clean.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 3 corresponding to the embodiments. The present invention has an opening 8 formed at one end. The other end is covered with a lid 3 having an inlet 3a to form a cylindrical cylinder 2. Then, there is a discharge hole 1 at the top of the tip.
A dish-shaped recess 1b having a diameter of 1.a is provided, and a higher step 1e is provided at the rear, and a gap is provided in the inner wall of the cylinder 2 that is continuous with the step 1e and allows water to pass therethrough, thereby forming a pressing portion 1f that is slidable by water supply pressure. Providing and pressing part 1f
A nozzle 1 is formed by providing an inlet 1g communicating with the discharge hole 1a on the side surface. Further, the nozzle 1 is housed inside the cylinder 2 with a gap provided between the nozzle 1 and the opening 8 of the cylinder 2 so as to be able to protrude freely.

Then, a ring 6 provided with an elastic body 7 in the cylinder 2 is loosely fitted with a gap that allows water to pass through, and a packing 4 is attached to the outer periphery of the base of the first step portion 1e of the nozzle, and the ring 6 and the nozzle are fitted together. 1
A spring 5 is provided between the pressing portions 1f to bias the nozzle 1 in the direction of housing the nozzle 1 in the cylinder 2.

(Function) According to the above-mentioned means, when the valve (not shown) is opened during use, cleaning water flows into the cylinder 2 from the inlet port 3a at the rear of the cylinder 2, and is caused by the inflow water pressure. Pressing part 1f of nozzle 1
is extended (moved) toward the outside of the opening 8 of the cylinder 2 against the spring 5. At this time, some of the inflow water enters from the inlet 1g of the nozzle 1 and enters the discharge hole 1a.
However, the force is weak, and most of the inflow water passes through the gap between the pressing part 1f of the nozzle 1 and the inner wall of the cylinder 2, and then the gap between the inner wall of the ring 6 and the nozzle outer periphery 1c, and flows between the nozzle outer periphery 1c and the opening. It flows out from between the inner wall of the part 8 and self-cleans the outer circumference 1c of the nozzle. (Self-cleaning is also performed when the nozzle 1 returns to the cylinder 2.) When the nozzle 1 moves further, the packing 4 comes into contact with the ring 6 and closes the gap, so all the water that has flowed into the cylinder 2 is removed from the inlet port. Discharge hole 1 via 1g
From a, the liquid begins to be discharged vigorously through the dish-shaped recess 1b with an appropriate spread and a soft sensation. This state is the state in which the nozzle 1 has completed extension as shown in FIG. That is, high water pressure flows into the cylinder 2,
Even if the packing 4 attached to the nozzle outer periphery 1c violently hits the ring 6, the impact is absorbed by the elastic body 7, so that the packing 4 does not deteriorate as in the conventional system.

When the valve (not shown) is closed after use, the pressure inside the cylinder 2 drops rapidly, and at this time, the shape of the elastic body 7 tries to return to its original shape, so this restoring force is applied to the ring 6 to cause packing. 4 and the nozzle 1 in the storage direction, the set load of the spring 5 can be reduced accordingly.

(Example) An example of the present invention will be described below based on FIGS. 1 to 3.

2 has a circular opening 8 at the bottom of a cylinder with a bottom, and a tapered surface 2 from the opening 8 toward the inner wall of the cylinder.
a and the other end is a washing water inlet 3a.
It is a cylinder made of synthetic resin and can be removably sealed with a lid 3 provided with.

1 is a cylindrical nozzle that has a diameter that allows it to be inserted into the opening 8 of the cylinder 2 with a gap, and has a length that excludes the thickness of the lid 3 from the entire length of the cylinder. 1 to the outside to clean the discharge hole 1a and the surrounding area of the nozzle 1, and the discharge hole 1a on the upper surface of the outer periphery of the tip.
A dish-shaped recess 1b is formed. At the rear of the nozzle 1 inside the cylinder 2, a gap is provided between a higher step 1e and an inner wall of the cylinder 2, which is provided even higher next to the step 1e, to allow water to pass through. A pressing portion 1f to be pressed is formed, and an inlet 1g communicating with the discharge hole 1a at the tip portion is formed on the side surface of the pressing portion 1f on the side of the inlet 3a. 6 is cylinder 2
It is a ring with an inverted L-shaped cross section that is loosely fitted with a gap that allows water to pass through the outer circumference of the inner nozzle 1. On the outer circumference of the ring 6, there is an elastic body 7 made of synthetic rubber or the like that comes into contact with the tapered surface 2a of the cylinder 2. are provided around the area.

4 is provided around the outer periphery of the base of the nozzle 1 step part 1e, and the pressure part 1f of the nozzle 1 is pressed by the inflow water pressure from the inflow port 3a, and the nozzle 1 is pushed into the cylinder 2.
It is a packing made of synthetic rubber or the like that comes into contact with the ring 6 when it is fully protruded from the opening 8 and closes the gap between the nozzle 1 and the ring 6.

5 is attached between the ring 6 and the pressing part 1f of the nozzle 1, and the protruding nozzle 1 is attached to the cylinder 2.
This is a spring that biases the device in the direction of storage.

In the above embodiment, since the protrusion 1d is provided at the tip of the nozzle 1, in the unlikely event that the discharge hole 1a and around the nozzle 1 become clogged with water scale, dirt, etc., discharge failure and nozzle expansion/contraction failure may occur. Also, by pulling and pushing the protrusion 1d at the tip of the nozzle by hand, cleaning can be easily performed.

(Effects of the invention) Therefore, since the present invention has the above configuration, it has the following effects.

1 A ring with an elastic body that comes into contact with the tapered surface of the cylinder is loosely fitted around the outer circumference of the nozzle in the cylinder, so even if high water pressure is suddenly applied to the pressure part of the nozzle, the elastic body will not hold the cushion. As a result, there is no deterioration of the packing and the durability has been greatly improved.

In addition, when the water pressure disappears after cleaning, the restoring force of the elastic body is added to the return force of the spring, so even if the spring pressure is weak, the nozzle will not stick to the inner wall of the cylinder due to water scale, and the nozzle will be reliably installed. stored inside the cylinder. Therefore, since the spring pressure can be set lower, a highly reliable nozzle device that can reliably expand and contract even in a low water pressure region can be obtained.

2. Since the nozzle tip is provided with a concave portion having a discharge hole, optimal spreading and a soft cleaning sensation can be obtained even if the discharge amount is small.
