Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an eyewash.
[0002]
[Prior art]
For example, as disclosed in Japanese Patent Laid-Open No. 9-225003, there is known an eyewash device that has a battery and a motor and is provided so that washing water is ejected from a shower portion by operating an operation button.
[0003]
[Problems to be solved by the invention]
The conventional eye wash is inevitably expensive because it is electrically driven and the structure is complicated.
The present invention is a hand-held eyewasher that has a simple structure and is easy to operate.
[0004]
[Means for Solving the Problems]
As a first means, the lower cylinder of the vertical cylinder 2 is closed with an inverted dome-shaped elastic bottom wall 3 projecting downward, and a holding cylinder having an engaging ridge 5 on the inner surface of the upper edge from the center of the elastic bottom wall. 4 to stand 4 upright,
From the upper end of the insertion tube 12 that is water-tightly fitted to the upper inner surface of the vertical tube portion 2, the abutment tube 13 that expands upward and outward is raised, and the lower end from the center portion of the bottom plate 14 at the lower end of the insertion tube The connecting rod 16 is suspended and the enormous portion 15 is engaged with the lower surface of the engaging protrusion 5 so that it cannot be pulled out into the lower part of the cylindrical hole of the holding cylinder.
Further, by making several elongated holes 17 in the outer peripheral portion of the bottom plate 14 at substantially equal intervals, the outer peripheral surface of the bottom plate central portion 14a and the inner peripheral surface of the lower end of the insertion tube are equally spaced. It consists of a main member 11 provided in a shape connected at both ends of elastic thread pieces 18 of substantially the same length protruding in the circumferential direction,
The central part of the bottom plate 14 is formed to be movable up and down through the connecting rod 16 by the vertical movement of the central part of the elastic bottom wall 3.
[0005]
A ventilation groove 19 was formed in a part of the upper end surface of the abutting tube 13 while having the first means as the second means.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings, the eyewash device of the present invention includes a base tube and a main member assembled to the base tube.
The base cylinder 1 is closed by an inverted dome-shaped elastic bottom wall 3 projecting the lower end surface of the vertical cylinder part 2 downward, and the holding cylinder 4 is erected from the center of the bottom wall. The holding cylinder is for fitting a connecting rod, which will be described later, and has an engaging protrusion 5 on the inner surface of the upper end.
[0007]
The main member 11 stands upright from the upper end of the insertion tube 12 that is watertightly fitted to the upper inner surface of the vertical tube portion 2 and extends upward and outward from the center of the bottom plate 14 at the lower end of the insertion tube. A connecting rod 16 having a lower end 15 as a bulging portion 15 is suspended, and the bulging portion is fitted into the holding cylinder 4, and the upper surface of the bulging portion is engaged with the lower surface of the engaging protrusion 5 so that it cannot be removed. . The fitting may be performed by forced pushing.
[0008]
As shown in FIG. 2, the bottom plate 14 has a plurality of elongated holes 17 formed in the outer peripheral portion thereof, so that the bottom plate central portion 14a excluding the outer peripheral portion of the bottom plate and the inner peripheral surface of the lower end of the insertion tube 12 are The bottom plate central portion 14a is resistant to the elasticity of each elastic thread piece 18, and is formed in a shape that is connected at substantially equal intervals by several elastic thread pieces 18 that protrude in the same circumferential direction and have substantially the same length. Thus, it is formed to be movable up and down with respect to the lower end of the insertion tube 12. In the illustrated example, the three elongated holes 17 and the three thread pieces 18 are provided, but they may be addressed to two or four, respectively.
The aforementioned base tube 1 and the main member 11 are formed of a synthetic resin material having elasticity.
[0009]
The above eyewash can be used, for example, as follows. When washing water is put into the base tube 1 and the main member 11, the upper end of the contact tube 13 is pressed around the eye, and the central portion of the elastic bottom wall 3 is moved up and down, the connecting rod 16 moves up and down together with the bottom plate central portion 14a. The whole washing water is stirred with this, so that the eyes can be washed with the stirred water. The inside of the eyewash is pressurized by pushing up the elastic bottom wall 3, and the pressurized state is canceled by restoration, but by forming a ventilation groove 19 in a part of the upper end of the contact tube, Pressurization can be prevented. When the groove is not provided, the pressure contact of the upper end of the contact tube 13 to the face can be partly performed. When the groove is provided, the eye wash is performed with care so that the washing water does not leak from the groove.

【The invention's effect】
In the present application, the lower end surface of the vertical cylindrical portion 2 is closed by the inverted dome-shaped elastic bottom wall 3 extending downward, and the outer peripheral portion of the bottom plate 14 at the lower end of the insertion tube of the main member 11 is closed. By making several long holes 17 in the outer peripheral portion, the outer peripheral surface of the center portion of the bottom plate and the inner peripheral surface of the lower end of the insertion tube are substantially the same length protruding in the same circumferential direction at equal intervals. Since it is formed in a shape that is connected at both ends of the elastic thread piece 18, the insertion tube 12 is fitted in a watertight manner on the upper inner surface of the vertical tube portion 2, and the enormous portion at the lower end of the connecting rod 16 that is suspended from the center of the bottom plate 14 By fitting 15 into the holding cylinder 4 erected from the center of the elastic bottom wall 3 so that it cannot be pulled out, the upper bottom plate central portion 14a can be moved up and down through the elastic bottom wall 3 and thus washed. The entire water can be effectively stirred.
Further, by providing the ventilation groove 19 in a part of the upper end surface of the abutting tube 13, it is possible to prevent high pressure in the eyewasher and enhance the cleaning effect.
