Description

[Detailed explanation of the idea] This case concerns a spray head.

Spray heads are already well known in which a pressurized liquid is given a high-velocity turbulence (spin) and ejected from a nozzle to obtain a spray.

The present invention attempts to make it possible to easily obtain foam and liquid jets in addition to spraying by providing an additional member to such a spray head.

The illustrated embodiment will be described below.

In the figure, 1 is a head main body, and 2 is an additional member attached to the front part of the head main body, and these are molded from synthetic resin.

The head body 1 has a spray nozzle 11 in the center of the front surface that sprays pressurized liquid in a high-speed overflow.
The outer periphery 12 of the front end is formed to have a smaller diameter, and an engaging protrusion 13 is provided around the outer periphery of the front end.

The additional member 2 is attached to the outer periphery 12 of the front end of the head body 1.
an annular base 21 is provided which fits into the front end of the container, and an engagement groove 22 is provided around the inner periphery of the annular base which engages with the engagement protrusion 13 on the outer periphery of the front end of the container. A foaming plug 25 and a liquid collecting plug 26 are integrally connected to the upper and lower surfaces of the annular base 21 via hinges 23 and 24 with reversing springs.
These plugs 25, 26 are connected to the reversible spring hinge 2
The bends at 3, 24 allow for alternative engagement with the annular base and stretching allows for separation.

The foam plug 25 has a foam tube 251 in the center, intake holes 252 around the foam tube, and a protrusion 253 on the edge opposite to the hinge 23 with the reversing spring.
The foam tube 251 is made to protrude inward and provided with a ventilation notch 254 at its inner end, and has an inner periphery with a small inclination angle and gradually becomes smaller in diameter outward, and an opening at the outer end. It is formed with a relatively large taper so that it can be positioned just in front of the spray nozzle 11.

The liquid collection stopper 26 has a liquid collection tube 261 in the center and a projection piece 262 on the edge opposite to the hinge 24 with the reversing spring. The circumference has a large inclination angle and the diameter gradually decreases outward, and the opening at the outer end is formed with a relatively small taper so that it can be positioned just in front of the spray nozzle 11.

The hinges 23 and 24 with reversing springs are provided with normal main thin hinges 231 and 241 at two places on the left and right, and a reversing spring 23 consisting of a F-shaped leaf spring in the center.
2, 242, and both ends of the reversing spring are connected to the annular base 21, the foam plug 25, and the liquid collection plug 26 via thin-walled hinges 233, 234, 243, 244,
Thin hinges 233, 234, 2 at both ends of the reversing spring
43, 244 are the main thin hinges 231, 241
It is located behind the.

With the above configuration, when pressurized liquid is sent to the head body 1 in the state shown in FIGS. 1 and 2, it is sprayed from the spray nozzle 11.

Next, when the foam plug 25 is rotated downward, the foam plug fits into the annular base 21 as shown in FIG. 3, and this state is held by the reversing spring 232. When pressurized liquid is sent in this state, the spray nozzle 11 sprays the same as before, but the spray is collected by the inner periphery of the foam tube 251, and the outside air is injected into the intake holes 252 and the ventilation notches. 254..., and is ejected from the foam tube 251 as foam.

Further, when the liquid collecting stopper 26 is rotated upward, the liquid collecting stopper is fitted into the annular base 21 as shown in FIG. 4, and this state is maintained by the reversing spring 242. When pressurized liquid is sent in this state, it is sprayed from the spray nozzle 11 in the same way, but the spray is sufficiently collected by the inner periphery of the liquid collecting tube 261 and returns to liquid. It ejects in a line from.

According to the present invention, not only the conventional spray can be obtained, but also foam can be ejected by positioning the foam plug 25 in front of the head body 1, and the liquid collection plug 26 can be positioned in front of the head body 1. This makes it extremely easy to eject liquid, and the foaming stopper 25 and the liquid collection stopper 26 are connected to the hinge 2 with a reversing spring.
3 and 24 to the annular base 21, its position can be secured by the hinges 23 and 24 with reversal springs, whether it is placed in front of the head body 1 or separated from it. This is extremely convenient for use.

It is simple in structure and production, can be provided at low cost, and is extremely useful in practice.
