Description

[Detailed explanation of the invention] Eye and nose diseases such as so-called hay fever have been increasing in recent years, and in response to these diseases, this invention relates to a small nozzle that is used by connecting to a washer that is always automatically pressurized. It is something. Note that the nozzle referred to in this proposal is a general term for each component.

The nozzles used in conventional cleaning devices simply jet out cleaning water, and there is no way to adjust the amount of water or stop the water at the tip of the nozzle using a control device in the nozzle body. Therefore, since it is controlled at a location separate from the nozzle, both hands are tied up, and there is a risk that the cleaning water may be contaminated by backflow due to negative pressure from the pump. In general, patients with hay fever often want to wash their eyes and nose at the same time, but it is cumbersome to use an eye wash device and a nose wash device separately, and it is not suitable for the same purpose to be used for both purposes for the reasons mentioned above. . Further, even if a nozzle equipped with a control device used for car washing or the like is made smaller in size, it is considered to be inconvenient to use.

This proposal was made to solve these problems, and will be explained in detail with reference to the drawings. First, as shown in FIG. , 2a are provided, corresponding notches 5, 5a are also made on the sides of the hose connector 3 and the nozzle base 4, and the plate spring 1 is
Attach the punched parts 2 and 2a by pushing them open. Then, as shown in FIGS. 2 and 3, the nozzle pipe 7 is inserted from the rear end into the hole 6 provided at the center of the bottom of the nozzle base 4, and is screwed into the hose connector 3 or fixed with an adhesive. The hole 6 is made slightly larger than the diameter of the nozzle pipe 7 so that the entire nozzle can move up and down easily. A cylindrical gasket 8 is buried at the tip of the nozzle pipe 7, and a water injection hole 9 is provided at the rear of the gasket 8, and a groove-shaped recess 10 is provided at the outer periphery of the rear portion.
Then, a hole made in the center of the circular rubber plate 12 is inserted into the nozzle pipe 7, fitted into the recess 10, and attached to the rubber plate receiver 11 provided on the upper inner periphery of the nozzle base 4. Then, a nozzle cap 14 having a spout 13 at its tip is screwed into a screw 15 on the upper part of the nozzle base 4, thereby compressing the rubber plate 12, thereby forming a cleaning water reservoir 16.

The configuration of the present invention is as described above, but when in use, the nozzle is pressed directly under the eyes for eye washing, or directly against the nostrils for nose washing. In either case, the natural way to hold the nozzle is to hold it between your thumb and forefinger, but in this case, the amount of water can be controlled without changing it. That is, as shown in FIG. 3, by pressing the leaf spring 1 which also serves as a handle, the notch 5 of the hose connector 3 is
The entire nozzle is pushed out from the attachment point of the punched part 2a at the lower part of the leaf spring 1, leaving the nozzle pipe 7 fixed to the hose connector 3 and the central part of the rubber plate 12 fitted in the recess 10. Therefore, a gap is created between the gasket 8 and the spout 13, and water is sent from the washer along with the air flow, passes through the water injection hole 9, fills the cleaning water reservoir 15, and is then jetted out. If the leaf spring 1 is pushed strongly, the gap will become larger and the amount of water will increase, but if it is loosened, it will decrease, and if it is completely returned to its original position, the water will stop. Note that the rubber plate 12 forms the cleaning water storage section 15 and also serves as a seal to prevent water leakage from there.
When in use, the central portion bends downward, and when use is stopped, it returns to its original shape and water is stopped by a gasket 8 buried at the tip of the nozzle pipe 7. This is due to the synergistic elastic action of the leaf spring 1 and the rubber plate 12. Therefore, no other coil springs are required. In addition, since the water stops at the tip of the nozzle, if you connect the nozzle of this invention to a washer that is constantly pressurized during use,
In addition to not contaminating the washing water due to backflow, it is also possible to wash the eyes and nose at the same time since both hands are not tied up.
