Description

[Detailed description of the invention] This invention is a water sprinkler switch that can be attached to a water faucet and can dispense water in the form of a shower or rectify the water so that it does not splash even if it hits utensils. Regarding.

A water sprinkler switch capable of dispensing water in the form of a shower or in the form of a rod is well known, for example, from Japanese Utility Model Publication No. 52-39316 and Japanese Utility Model Publication No. 56676.

However, the problem is that if you use a stick to spray water, when the water hits the utensils, the water will splash and wet the surrounding area.

Therefore, the present invention improves this, and when switching from the shower type, some of the water comes out from one hole in the shower, but the remaining water passes through the porous rectifier tube and comes out by wrapping around the water spray coming out from the Java hole. As a result, the present invention has been improved so that it can be used without splashing even if it hits objects.Hereinafter, the present invention will be explained with reference to an embodiment shown in the drawings.

Reference numeral 1 is a base having a mounting opening 2 facing downward in the center of the upper part, which is attached to the outer periphery of the faucet.In this case, it has the same conical shape as S, but the shape can be arbitrary, for example, it can be shaped like a lower arm or cylindrical. It can also be a shape.

The base body 1 is longer than the lower end of the mounting port 2 (has a cylindrical wall 3 that protrudes downward, and the mounting port 2 is
An annular valve seat 4 projects inward at a distance below the lower end of the valve seat 4.

It is preferable that the base body, especially the mounting opening 2, has enough elasticity to be easily fitted into the faucet and to be able to strongly grip the faucet when it is pressed by water pressure from around it when in use. Preferably, the wall has a degree of hardness that prevents it from being deformed by water pressure.

For this reason, in the illustrated embodiment, the mounting port 2 and the cylindrical wall 3 are molded from soft synthetic resin, and the valve seat 4 and a reinforcing tube that protrudes downward from the outer periphery of the valve seat and is press-fitted into the inner periphery of the cylindrical wall 3. 4' is integrally molded with relatively hard synthetic resin, a reinforcing tube 4' is fitted and glued to the inner periphery of the cylindrical wall 3, and if necessary, a reinforcing ring 3' is fitted to the outer periphery of the cylindrical wall 3 to secure the base. (Assembling) Yes.

However, the mounting port 2 may be made of soft synthetic resin, the cylindrical wall and the valve seat may be made of hard synthetic resin, and the base body may be made into one piece.

Reference numeral 5 denotes an operating body that can be fitted into the base 1 from below and moved up and down, and includes an operating barrel 6 that can be fitted into the cylindrical wall 3 of the base 1 from below and moved up and down, and an inner periphery of the operating barrel. A valve cylinder 7 that protrudes long below the lower end of the operating cylinder and moves up and down together with the operating cylinder, a perforated plate 8 provided at the lower end opening of the valve cylinder 7, and a perforated plate 8 whose upper end is connected to the operating cylinder. At the lower end, there is a porous rectifier cylinder 9 whose lower end is joined to the outer periphery of the lower end of the valve cylinder.

In this embodiment, screws are attached to the inner periphery of the cylindrical wall 3 of the base body, to the inner periphery of the reinforcing cylinder 4' which is glued and fixed to the inner periphery of the cylindrical wall in this case, and to the outer periphery of the inner cylindrical part 6a of the operating cylinder. 10, and by turning the operating body 5 and tightening the screw, the operating body rises with respect to the base body, and in the highest state, the upper end of the valve cylinder 7 comes into contact with the valve seat 4 of the base body from below. ing.

Therefore, when the mounting port 2 is attached to a faucet and the operating body is raised to the highest level to dispense water from the faucet, the water passes through the valve barrel 7 and exits from the perforated plate 8, forming a shower-like shape.

Also, when the operating body is turned in the opposite direction and the upper end of the valve cylinder is released downward from the valve seat 4, some of the water coming out of the faucet passes through the valve seat and the upper end of the valve cylinder, and flows into the outer periphery of the valve cylinder and the inside of the rectifier cylinder 9. It comes out at intervals around the circumference, permeates through the porous wall of the rectifying tube and exits.

Further, the remaining water comes out from the perforated plate 8 at the lower end of the valve barrel.

Therefore, the flow that is rectified after passing through the cylindrical wall of the rectifier tube wraps around the shower-like flow that comes out from the perforated plate 8, so that water will not splash even if it hits the utensils.

Thus, according to the present invention, it is possible to provide an unprecedented water sprinkler switch for a faucet that can output water in a shower-like manner or in a rectified manner so that water does not splash on utensils.

When the operating body is raised to its highest position, the water pressure from the faucet is applied to the valve seat 4 from above, pressing the valve seat against the upper end of the valve cylinder 7, so that water does not leak into the rectifying cylinder.

The vertical movement of the operation tube relative to the base body is performed using screws in this example, but this can be achieved by, for example, having an inclined groove or hole in one of the operation tube 6 and the cylinder wall 3 of the base body, and the groove or hole in the other side. A protrusion that engages with the hole is provided, and the protrusion is moved vertically in the groove, and when the operating body is raised to the highest level, it is rotated slightly to push the protrusion into the horizontal part of the upper end of the groove, and the highest state is maintained. It can also be done in different ways.

The valve cylinder 7 may be integrally connected to the inner periphery of the operating cylinder 6 with a suitable connecting part 11 such as an arm spaced apart in the circumferential direction or an annular wall having holes in the circumferential direction, or it may be molded separately. Then, connect them by gluing or the like.

Furthermore, in the operating cylinder 6), an inner cylinder 6a that fits into the inner circumference of the cylinder wall
It consists of an outer cylinder 6b that fits around the outer periphery of the cylinder wall, and has an S'U-shaped cross section, but this is not necessarily necessary and either the inner cylinder or the outer cylinder may be used.

When having an inner cylinder and an outer cylinder like this, a hole 6' is provided at the bottom that connects the two cylinders, so that water leaking onto the fitting surface of the cylinder wall 3 and the operating cylinder 6 is drained from this hole 6'. Just do it.

Furthermore, in this embodiment, the lower end of the valve cylinder is enlarged in diameter into a trumpet shape, but this is to join the lower end inner circumference of the cylindrical rectifying cylinder 9, so the valve cylinder is shaped like a right cylinder. The diameter of the rectifier tube may be narrowed at the lower end.
