Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to the structure of the tip portion of a flash valve type gun water sprinkler represented by a simple flush toilet, The purpose is to raise.

[Prior Art] Cleaning a toilet bowl requires a certain amount of water and water pressure. There are three methods for that purpose: low tank type, high tank type, and flash valve type.

The low tank type is a method to attach the washing tank 40 to 50 cm above the floor surface, and there are flat type, tightly bound type, corner type,
Most are hand-washed on the top.

The high tank type is a system in which a container made of ceramics, plastic, etc. is installed at a position 180 cm or more from the floor surface, and the container is washed by the drop of water.

Since these two methods do not allow the user to select the cleaning location in the toilet bowl, the amount of water required for each cleaning (usually equal to the tank capacity) is set to be very large. This is not only from the viewpoint of effective use of water resources, but in areas where public sewers are not fully equipped, it is necessary to store them in a private human waste tank, etc. Because of the drawback of increasing the number, many areas regulate the tank-type water washing system by laws and regulations.

On the other hand, the flash valve method is a method to flush the valve using the water pressure of tap water by opening the valve of the water sprayer directly connected to the water supply. It has the characteristic of being able to. Therefore, the cleaning ability is superior to other methods, and as a practical method,
Generally, a simple and highly efficient flushing method per volume of water is used, in which the entire toilet bowl is first washed with a small amount of water (in the case of flushing after urine, this is all that is required), and then additional washing is performed with a gun type Has been taken.

[Problems to be solved by the invention]

However, since the flushing of the toilet with a gun-type water spouter is of a type in which the water pressure required for washing depends on the water pressure of tap water, the strength adjustment is handled exclusively by adjusting the distance between the washing point and the water spouter. However, various inconveniences have been problems.

In other words, the nozzle opening of the gun-type water sprayer is extremely small in order to enhance the cleaning effect, and water is discharged in such a manner that the cleaning points are concentrated at a very small point in order to clean with a strong pressure. However, in reality, such a strong pressure is rarely required, and because of its strength, it often wets the outside of the toilet bowl and hands with the splashes, and since there is only one cleaning point, it is necessary to clean a certain area. Since the water discharge location has to be moved diligently, there is a drawback that it takes time and the amount of water.

[Means for solving problems]

Therefore, the present inventor has completed the present invention as a result of earnest research in view of the above points, and is characterized by the tip of a flush valve type toilet bowl cleaning gun-type water spout It is composed of a screw groove engraved on the end and a tip member having a screw groove in its inner periphery that can be screwed, a small circular hole is provided at the tip of the main body side, and a long hole is provided in the tip member. Is that they are screwed together with elastic body packing.

That is, it is the greatest feature that a nozzle having a long hole opening is added to a tip member having a nozzle opening that discharges water as a single line by itself. In addition, it can be tightened by packing each with a screw groove to adjust the direction of the water discharged in a diffused form by the nozzle of the long hole opening, or to remove this nozzle and make it a normal water discharger It is what

In addition, the "main body" referred to in the present specification refers to one excluding the middle tip member of the gun type water sprinkler. This is a flush valve system in which a valve is opened by a switch and tap water is ejected, and there are various structures and shapes, but the present invention is not particularly limited thereto. Further, the water discharge nozzle portion is usually attachable / detachable to the tip on the main body side (to the muzzle portion of a gun), but the concept of "main body" also includes the water discharge nozzle portion.

The "tip member" is a member having a screw groove in its inner peripheral portion and has a long hole at its tip. The material is not particularly limited, but metal or synthetic resin excellent in rust resistance and strength is preferable.

The "small circular hole" is an opening for discharging a thin linear water and is similar to the opening of a conventional gun-type water sprayer.

The “long hole” is a hole corresponding to the small circular hole, refers to an opening that allows diffusion type water discharge, and is provided on the tip member side. This may be carved so as to simply penetrate the tip member, or carved with an inclined groove.

The "elastic body packing" is a packing made of an elastic material such as rubber or synthetic resin, and is a member for giving a so-called play to the screwing.

〔Example〕

The present invention will be described in more detail with reference to the embodiments shown in the drawings.

FIG. 1 is a gun-type water sprinkler having a tip structure according to the present invention.
It shows one of the embodiments of (1) (hereinafter, simply referred to as "water discharger (1)"). As is clear from the figure, the water discharger (1)
It can be divided into a main body (2) and a tip member (3). In addition, the main body (2) consists of a hose (20) that connects to the tap and a gun.
(21) and the tip of the main body (22) can be divided.
Screw grooves (23) and (31) are formed on both members of the main body (2) and the tip member (3) so as to be screwed. A rubber packing (4) is provided between them.

Due to the presence of the packing (4), there is some margin in the sealing by screwing. It was confirmed that in the present example, the hermeticity is maintained in the range in which the tip member (3) is rotated about 180 °.

Next, FIGS. 2 and 3 clarify the structure of an embodiment of the tip member (3). The tip member (3) diffuses tap water to be ejected by attaching the tip member (3), and therefore, as apparent from FIG. 3, the tip member is provided with a long hole (32). Further, in the case of this example, the elongated hole (32) has a V-shaped inclined groove (3) for controlling diffusion of water.
2) is involved.

Thus, in the case of this example, water is discharged in the form of forming a strip-shaped surface (A) in the toilet bowl (Fig. 4). Moreover, since the tip member (3) can be rotated while keeping the seal, it is possible to freely change the direction of the belt-like surface (A) as is clear from the broken line part of the figure, which is the optimum water discharge state for cleaning. Can be obtained.

[Effect of device]

As described above in detail, the present invention relates to the structure of the tip member of a flush type gun-type water sprayer for flushing a toilet, and a screw that can be screwed into a screw groove engraved on the outer periphery of the body side tip. The main body side tip is provided with a small circular hole, the tip member is provided with an elongated hole, and both members are screwed together with elastic body packing. It is characterized by being a thing, making it possible to discharge a gun type water sprayer that was conventionally only able to discharge water only in the form of a strip,
Further, due to the presence of the elastic body packing, the band-shaped water discharge surface can be appropriately rotated as necessary by rotating the tip member slightly along the screw, and if necessary, the tip member can be removed to remove the conventional member. It is a very useful device for practical use, which has the advantages that it can be easily used as a linear water discharge type.
