Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a double electrode connection structure of an electrolytic disinfector for contact lenses. More specifically, the present invention is an electrode that can ensure electrolysis and improve its efficiency in the electrode section of a device that disinfects contact lenses with sodium hypochlorite generated by electrolyzing saline. The present invention relates to a double electrode connection structure of an electrolytic disinfector for contact lenses having the following.

[Conventional technology] Conventionally, in order to disinfect contact lenses, contact lenses are immersed in saline solution.
A method and apparatus for disinfecting contact lenses with sodium hypochlorite by generating sodium hypochlorite in the saline solution by passing an electric current through the saline solution are used (Japanese Patent Laid-Open Publication No. 56-68454 and JP-A-56-130713).

However, when these contact lens disinfection devices are used for a long period of time, dust and salt may be deposited between the electrodes of the electrolytic disinfection device and the electrodes of the contact lens storage case. This may cause contact failure between these electrodes, causing current to no longer flow to the electrodes of the contact lens storage case, or even if current does flow, the amount of electricity is insufficient, resulting in insufficient disinfection of contact lenses. Problems such as this could occur.

Therefore, as a contact lens disinfection device that can solve the above-mentioned problems, by fitting a contact lens storage case and an electrolytic disinfection device main body, the electrodes of the electrolytic disinfection device main body are securely connected to the electrodes of the contact lens storage case. An electrolytic disinfection container has been developed that has a mechanism that allows it to be brought into close contact with the container (see Japanese Utility Model Application Publication No. 189021/1983).

[Problems to be solved by the invention] The electrolytic disinfection container is capable of bringing the electrodes of the electrolytic disinfection device body into close contact with the electrodes of the contact lens storage case. A high degree of dimensional accuracy is required for the fitting part of the product, and the dimensional accuracy of the fitting part deteriorates during repeated use.
A problem may arise in which poor contact occurs between the electrodes.

Therefore, the present invention was created in view of the above-mentioned problems, and it is possible to solve the above-mentioned problems by repeatedly using the electrode of the electrolytic disinfection device body and the electrolytic electrode of the contact lens storage case. Even if dust or salt gets between the electrodes, the amount of electricity will not decrease even if dust or salt gets into the space between the electrodes.
An object of the present invention is to provide a double-electrode connection structure of an electrolytic disinfector for contact lenses that can electrolyze saline in a contact lens storage case.

[Means for Solving the Problems] That is, the present invention provides a two-electrode connection structure for an electrolytic disinfector for contact lenses, which comprises a disinfector body housing a power source and a storage case that can be attached to and detached from the electrode part of the disinfector body. The present invention relates to a two-electrode connection structure for an electrolytic disinfector for contact lenses, characterized in that an electrode provided on the electrolytic disinfector body and an electrode mounting plate are connected via an elastic support.

[Operations and Examples] Next, the electrode connection structure of the electrolytic disinfector for contact lenses of the present invention will be explained with reference to the drawings.

FIG. 1 is a cross-sectional view of a main part of a two-electrode connection structure of an electrolytic disinfector according to an embodiment of the present invention.

In FIG. 1, 1 is the main body of the electrolytic disinfector, 2 and 3 are electrodes, 4c is an elastic support, 5 is an electrode part, 6 is an electrode mounting plate, 7 is a guide plate, 8 is a top lid of the electrolytic disinfector, 9 is a power supply section.

In addition, in FIG. 1, the support body 4c is integrally molded with the protrusion part 4a and the side end part 4b, and the elastic body 4 is formed by the support body 4c, the protrusion part 4a, and the side end part 4b.

Electrodes 2 and 3 are usually platinum electrodes that do not cause corrosion or other changes even when immersed in saline water for a long period of time, or metals such as copper or nickel, or synthetic resins that are plated or vapor-deposited with gold or platinum. Treated electrodes are used. The electrodes 2 and 3 are connected to an elastic body 4 fixed to an electrode mounting plate 6.
Convex portions 2a and 3a are provided to determine the fixed position when fixing the electrodes and to prevent the electrodes 2 and 3 from coming off, respectively. Further, the lower ends 2b and 3b of the electrodes 2 and 3 are connected to the conductive wire 1.
It is connected to the power supply unit 9 through 0 and 11.

The elastic body 4 includes natural rubber, sterene-butadiene rubber, butadiene rubber, chloroprene rubber, butyl rubber, nitrile rubber, ethylene-propylene rubber, acrylic rubber, urethane rubber, and silicone rubber, which have excellent electrical insulation and flexibility. , fluorine rubber, etc. are used, but among these, silicone rubber is particularly suitable for use because it has a high degree of weather resistance and chemical resistance, and is also excellent in hygiene. In addition, in order to prevent salt water from entering between the elastic body 4 and the electrodes 2 and 3,
It is preferable that the inner diameters of the attachment portions and 3 be slightly smaller than the outer diameters of the electrodes 2 and 3, so that the elastic body 4 and the electrodes 2 and 3 are brought into close contact with each other. The means for adhering the elastic body 4 and the electrodes 2 and 3 may be any method such as friction between the two, fitting by a locking portion, adhesive, or a fusion method. Furthermore, the elastic body 4
It is preferable to provide the protruding portion 4a in order to prevent electricity from flowing through the saline and occurrence of defective electrolysis even if the saline leaks onto the top. The side end 4b of the elastic body 4 is fixed with an electrode mounting plate 6, and the top cover 8 of the electrolytic disinfector is crimped onto the upper surface of the side end 4b, and the saline solution is poured into the main body of the electrolytic disinfector on this surface. is prevented from entering.

The guide plate 7 serves as a guide provided to move the electrodes 2 and 3 in the direction of the lead core.

Although the upper lid 8 is fitted to the electrolytic sterilizer main body 1 in FIG. 1, in the present invention, it may be fixed not only by such fitting but also by adhesive, screw fitting, etc. .

The electrode portion 5 of the electrolytic disinfector main body 1 is provided with a threaded portion 5a, and as shown in FIG. 6, the storage case 12 can be rotated and inserted into the electrode portion 5 and fixed.

At this time, the electrodes 2 and 3 are placed in the storage case 12.
At the same time, the elastic support 4c is stretched.

The support body 4c holds the electrodes 2 and 3,
Provided to connect the electrodes 2 and 3 and the electrode mounting plate 6. The thickness of the support body 4c is the same as that of the support body 4c.
Since the mechanical strength varies depending on the material of c, it cannot be determined unconditionally, and is usually determined by considering the support strength of the electrodes 2 and 3 and the tensile strength when the storage case 12 is attached. In order to easily attach the storage case 12 by pushing down the electrodes 2 and 3, it is preferable that the elastic body 4 is thinner than the other portions of the support 4c.

Note that the support body 4c is made of an elastic body 4 in terms of strength.
It is preferable that the support 4c, the side end 4b and the protrusion 4a are made of the same material as the side end 4b and the protrusion 4a, and that the support 4c, the side end 4b and the protrusion 4a are integrally formed.

In addition, when the support body 4c is provided so as to be inclined from the electrodes 2 and 3 toward the electrode mounting plate 6 as shown in FIG.
When attached to the support body 4c, the overall elasticity is generated by the elasticity of the support body 4c itself and the elasticity generated from the shape. Compared to the case where the electrodes are attached to an elastic body 4 having a bellows-like support 4c as shown in FIG. This is preferable because it can be pushed downward.

Next, when the storage case 12 is removed, the support body 4c contracts to its original shape.

As described above, in the present invention, the elastic body 4 plays the role of preventing saline from entering into the electrolytic disinfection device main body 1, and also uses the elastic force of the support body 4c to prevent contact lenses 15 and 16 from being inserted. When the stored storage case 12 is mounted inside the electrode section 5, the electrodes 2 and 3 and the electrolytic electrodes 13 and 14 are reliably crimped, thereby preventing contact failure of the electrodes. Furthermore, even if dust or the like is attached to the electrodes 2 and 3 or the electrolytic electrodes 13 and 14, the storage case 12 is inserted into the electrode part 5,
When the storage case 12 is rotated and fixed, the electrodes 2 and 3 and the electrolysis electrodes 13 and 14 are rubbed against each other, which is preferable because dust and the like are removed.

In FIG. 1, in order to prevent the contact positions between the electrodes 2 and 3 and the electrolytic electrodes 13 and 14 from shifting, positioning protrusions are provided on the threaded portion 5a of the electrolytic disinfector main body 1 or the threaded portion of the storage case 12. For example, the electrolytic disinfector main body 1

Also, instead of the threaded portion 5a used in the electrolytic disinfector main body 1 shown in FIG. 1, an electrolytic disinfectant main body having a structure as shown in FIG. If 1 is adopted,
This is preferable because the storage case 12 can be easily attached to the electrolytic sterilizer body 1 by simply inserting the electrolytic sterilizer body 1 into the electrode part 5 and pressing it.

In FIG. 5, 17 is a spring-like protrusion;
It serves as a positioning (guide) when inserting the storage case 12 into the electrode part 5, and also serves to prevent the storage case 12 from coming off when it is attached. Further, 20 is a member forming the bottom surface of the electrode section.

FIG. 2 is a sectional view showing a state when the storage case 12 is inserted and fixed into the electrolytic disinfector main body 1 shown in FIG. 5. .

In addition, when using a support body 4c with a small elastic force, springs 18 and 19 are provided between the convex portions 2a and 3a of the electrodes 2 and 3 and the guide plate 7, as shown in FIG. It's okay.

Further, in order to drain spilled saline solution, a hole may be provided in a part of the elastic body 4 and communicated with the outside so that the saline solution can be discharged to the outside without leaking into the electrolytic sterilizer main body 1. .
