[0014]
In each of the above embodiments, the same reference numerals are given to the same structural parts, and the description is omitted.
In each of the above embodiments, in the case of the first embodiment shown in FIGS. 1 and 2 and the second embodiment shown in FIG. 3, the pressurizing cylinder passes through the liquid storage cylinder 6 and the water passage hole 8. When an appropriate amount of washing water is put into the part 1, the outward flange at the upper end of the liquid storage cylinder is applied to the face portion around the eye, and the elastic bellows cylinder parts 3 and 3 are elastically squeezed, the inside of the pressure cylinder part 1 is increased in pressure. Thus, as shown in FIG. 2, the washing water in the pressure cylinder portion is ejected upward through the water passage hole 8 and can be washed with the ejection water. When the upper end surface of the liquid storage cylinder 6 is brought into close contact with the face when the liquid is ejected, the inside of the cylinder is increased in pressure, and the inside of the liquid storage cylinder 6 is restored due to the elastic restoration of the pressurizing cylinder 1 by releasing the bellows cylinder. The negative pressure can be eliminated by separating a part of the upper end surface of the liquid storage cylinder from the face, or by providing the ventilation recess 7 on the upper end surface of the liquid storage cylinder.
[0015]
In the case of the third embodiment shown in FIGS. 4 and 5 and the fourth embodiment shown in FIG. 6, an appropriate amount of cleaning water is put into the liquid storage cylinder 6, and the case of the first and second embodiments. If the bellows-like cylindrical portions 3 and 3 are squeezed in a state where the upper end surface of the liquid storage cylinder is applied to the face portion around the eye and the outside air suction hole 25 is closed with a finger or the like, the air in the pressurized cylinder 1 is reversed. Since the stop valve 30 is opened and the washing water is raised, the eyes can be washed with the above-mentioned washing water. Air released above the water surface is released into the outside air through the ventilation recess 7 or the gap with the face, and is released by releasing the finger from the outside air intake hole and releasing the accordion tube portion. The pressure cylinder portion 1 is elastically restored.
[0016]
【The invention's effect】
Since the present invention has the above-described configuration, the pressure cylinder 1 is formed by attaching elastic bellows-shaped cylinders 3 and 3 that can be expanded and contracted to the left and right ends of the intermediate cylinder 2. The pressurization and negative pressure of the part can be performed by squeezing the bellows-like cylindrical part and restoring the elasticity, and since these can be operated with one hand, the operation is easy. Further, since the liquid storage cylinder 6 having an outer diameter larger than that of the support cylinder rises from the upper end of the support cylinder 4 rising from the intermediate cylinder portion, and the upper end surface of the support cylinder is closed by the bottom plate 9 with the water holes 8, the liquid storage cylinder It is easy to wash the eyes by spraying the washing water from the water passage hole 8 by pressing the upper end of the face 6 to the face portion around the eye and pressing the bellows-like cylindrical portions 3, 3. Since it can be returned, the washing water will not splash.
[0017]
Also in the case of the invention according to claim 2, since the pressure cylinder part 1 is formed by attaching the elastic bellows cylinder parts 3 and 3 to the left and right ends of the intermediate cylinder part 2, the case of the pressure cylinder part according to claim 1 Has the same effect as
A liquid storage cylinder 6 having an outer diameter larger than that of the support cylinder 4 is erected from the upper end of the support cylinder 4 rising from the intermediate cylinder portion 2, and the upper end of the support cylinder 4 is closed with a bottom plate 9 with a valve hole 26. A check valve 30 is formed by the valve hole 26 and the outer periphery of the elastic valve plate 29 pressed against the outer periphery of the upper surface of the valve hole by fitting the shaft 28 that hangs down from the center of the elastic valve plate 29 into the inside. The upper end surface of the cylinder 6 is applied to the face part of the outer periphery of the eye, and the air in the pressurized cylinder part is released into the liquid storage cylinder by the accordion-like cylinder parts 3 and 3, and the liquid in the cylinder is raised upward by the release. Thus, it is easy to wash eyes with the swelled washing water. Further, since the bellows-like cylindrical portions 3 and 3 are immediately elastically restored by releasing the outside air suction hole 25, it is possible to continue the re-pressing of the pressure cylinder portion having the bellows-like cylindrical portion.
[0018]
According to the third aspect of the present invention, the air in the liquid storage cylinder is discharged into the outside air through the recess 7 when the eye is washed by providing the recess 7 for ventilation on a part of the upper end surface of the liquid storage cylinder 6. In addition, since the outside air also flows into the liquid storage cylinder, it is possible to eliminate the trouble of separating the upper end surface of the liquid storage cylinder from the face or bringing it into pressure contact as in the case where the concave portion 7 is not provided.
