BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine for a portable contact lens, and more particularly, to a washing machine for a portable contact lens, which is portable and excellent in cleaning and disinfecting of a contact lens.

In general, contact lenses are worn in direct contact with the eye, so that fat may be attached to the lens surface from the eye and various foreign substances are attached from the outside, so that the eye is contaminated with various diseases by using a clean solution using saline or chemicals. You can prevent it. Therefore, since wearing the contact lens is required to be washed and worn as often as possible, there has been a steady study on the effective method for cleaning the contact lens.

Designed by Lim Sung-mook and filed with the Korean Patent Office and patented as No. 279,074, "Cleaning and sterilizing device for contact lenses" cleans contact lenses injected into a container containing saline using ultrasonic vibration and an ultraviolet lamp generated from a vibrator. Sterilization is disclosed. However, sterilization by ultrasonic waves using electric vibration force is not used for high hardness hard contact lenses due to the fear of damage, and there is a limit that they can be applied only to soft type contact lenses.

In addition, in order to remove bacteria or viruses attached to the lens or suspended in saline, it is difficult to obtain a sufficient effect by using only ultrasonic vibration generated in the vibrator.

Accordingly, there is a need for a portable contact lens cleaner that can be washed and sterilized regardless of soft type or hard type while being convenient to carry, and capable of sterilizing bacteria or viruses.

The present invention has been made to solve the above problems, and as a result of the more intense electrolysis to generate a large amount of oxidant in a short time to separate the foreign matter attached to the surface of the lens as well as to sterilize bacteria or bacteria in a short time. It is an object of the present invention to provide a cleaner for a portable contact lens that can be used.

In addition, another object of the present invention is to implement the function of the washing machine of the portable contact lens with a simple configuration, it is possible to make a compact and portable to wash the contact lens in any place, more affordable and portable It is to be able to manufacture a washing machine of the contact lens.

The present invention, in order to achieve the above object, a lens receiving portion for receiving a contact lens; An electrode portion having a negative electrode portion formed in the receiving portion and a positive electrode portion arranged in the receiving portion so as to be spaced apart from the negative electrode portion by a predetermined distance; A power supply unit supplying power to the negative electrode unit and the positive electrode unit; It provides a cleaner for a portable contact lens comprising a.

It supplies power to the negative electrode and the positive electrode and induces electrolysis therebetween, whereby the oxidized product removes and disinfects proteins and foreign substances attached to the contact lens placed in the lens receiving portion, and the virus. To sterilize and bacteria.

At this time, the negative electrode portion and the positive electrode portion are formed in the negative electrode portion and the positive electrode portion to face each other, so that more charge is concentrated on the negative electrode projection and the positive electrode projection, leading to more intense electrolysis therebetween.

When power is applied to the cathode projection and the anode projection that are spaced apart by a predetermined distance, the water between the cathode projection and the anode projection is electrically divided. At this time, oxidants such as ozone (O ₃ ), hydrogen peroxide (H ₂ O ₂ ), OH radicals, and HOCl are generated, and microorganisms, bacteria, and bacteria are sterilized by the oxidants. The production and sterilization of the oxidant by electrolysis is carried out by the following steps (1) to (5).

(1) Ozone is generated by electrolysis of water (H ₂ O) and finally ozone is formed through the following process where O and O ₂ are combined.

^{_{H 2 O -> H + +}} (OH) ads + e -

_{(OH) ads -> (O} ) ads + H + + e -

_{2 (OH) ads -> O} 2 + 2H + + 2e -

2 (O) _ads- > O ₂

(O) _ads + O _2- > O ₃

(2) Hydrogen peroxide is produced by the direct route by the electrolysis of oxygen and the indirect route produced by the combination of OH radicals, an intermediate product produced by ozone decomposition. In other words,

^{_{O 2 + e - -> O}} 2 · -

_{^{O 2 + 2H + + 2e -}} -> H 2 O 2

With a direct path such as

OH + OH-> H ₂ O ₂

Is generated by an indirect path such as

(3) HOCl reacts with H ₂ O to form HOCl after Cl ⁻ ions in water bind with Cl ₂ . In other words,

_{^{2Cl - -> Cl 2 + 2e}} -

^{_{2H 2 O + 2e - ->}} H 2 + 2OH -

_{Cl 2 + H 2 O ->} HOCl + H + + Cl -

(4) OH radicals are instantaneously produced and disappeared, so they cannot be measured directly, but when ozone is present in water, they react with OH ^- or a counterbase of hydrogen peroxide to form a radical chain cycle. Produces OH radicals.

O ₃ + OH-> Radial Chain Reaction-> OH

O ₃ + HO ^2- (covalent base of H ₂ O ₂ )-> radical chain reaction-> OH

(5) Microorganisms (microorganisms) present in water are inactivated or removed by the oxidants produced, and the following microorganisms are removed by electrosorption, and the following microorganics are e- and It is removed by direct electrolysis reaction.

In other words, for Microorgainsm

M (Microorganism)-> Electrosorption-> Inactivation

Also,

M (Microorganism) + O _3- > Inactivation

M + OH ·-> Inactivation

M + HOCl-> Inactivation.

And about Microorganics,

M (Microorganics) + e--> M-

Also,

M (Microorganics) + O _3- > Product

M + OH

M + HOCl-> Product

That is, during electrolysis, oxidation and sterilization is performed smoothly by the mixed oxidants (O 3, H 2 O 2, HOCl, OH radicals) generated in the process of (1) to (5), and electrolysis is performed. Afterwards, high sterilization power is maintained by high residual HOCl.

Hydrogen peroxide (H ₂ O ₂ ), which is produced during electrolysis, also has the ability to produce free radicals (HO · + O ·), which can convert proteins into low molecular weight peptides and amino acids. It breaks down into a water-soluble substance, and flocks to the double bond site to produce epoxides. More specifically, the free radicals produced in hydrogen peroxide are very reactive, oxidizing hydrogen peroxide by attacking other organic molecules such as proteins to achieve their stability. This breaks down the protein into amino acids to make it a water-soluble substance, which removes the protein from the surface of the contact lens.

In this way, by cleaning the contact lens using an oxidant generated through electrolysis, it is not only applicable to a hard type contact lens that could not be used due to the fear of damage in the past, but also a simple configuration of the contact lens. The cleaning and sterilization can be implemented, which contributes to the miniaturization of the washing machine of the portable contact lens.

At this time, the negative electrode portion and the positive electrode portion is formed in a plate shape, and on the surface facing each other is formed a projection having a pointed end or columnar shape such as conical to face each other, more charge to the projection Is aggregated to further promote the electrolysis reaction. In addition, the negative electrode portion and the positive electrode portion may be formed of a plurality of pairs of plates or bars so as to induce more electrolysis in the unit installation space.

On the other hand, the negative electrode portion formed in the shape of a plate and the branch plate branched from the plate surface of the positive electrode portion protrudes, the branch plate branched from the negative electrode portion and the branch plate branched from the positive electrode portion are arranged so as to face each other one by one, facing each other Cathodes and anodes are formed on the branch plates, respectively. Through this, it is possible to maximize the area where the electrolysis occurs in the minimum space. Further, another branch plate may be formed from the branch plate, and the cathode and anode protrusions may be formed on opposite surfaces of the other branch plates extending from the positive electrode portion and the negative electrode portion, respectively.

At this time, in order for the electrolysis reaction between the cathode projection and the anode projection to occur more violently, the cathode projection and the anode projection are preferably formed of platinum or plated with platinum. At this time, the platinum plating layer may be formed over the entire electrode portion, but it is more effective to plate thicker on the cathode projection and the anode projection.

On the other hand, instead of the positive and negative projections are formed, the same effect can be obtained by forming a groove around the concentration to concentrate the charge in a certain portion.

In addition, if the cathode projection and the anode projection are formed of platinum and formed to a certain size or more, only the projections may be replaced by a method such as screwing. Meanwhile, in order to reduce cost, the cathode protrusion and the anode protrusion may be titanium plated or formed of titanium.

In addition, an operation button is formed on the front of the outer case. Therefore, when the user puts the used contact lens on the lens housing and presses the operation button, power is applied to the electrode for the set time required for cleaning, and violent electrolysis occurs between the electrode parts. Contact lenses in the lens receptacle are cleaned and sterilized.

The washing machine of the portable contact lens according to the present invention can clean the contact lens more quickly by providing a vibrator that not only cleans and sterilizes the contact lens with an oxidant by electrolysis at the electrode portion, but also generates ultrasonic waves at the same time.

In addition, the disinfecting effect of the oxidant produced by electrolysis can be used for the purpose of spraying the sterilizing water into the nose of a person with rhinitis, so as to communicate with the lens receiving portion that is electrolyzed and sterilized, and a cleaner for the portable contact lens. It may be configured to further include a sprayer for spraying to the outside.

For the convenience of the user, the electrode unit may be used by receiving an external AC power, but is preferably configured to apply power to a battery that can be easily purchased on the market. The battery may be one that can be charged.

Then, in order to discharge the heat generated in the electrode portion to the outside, a heat dissipation fin for dissipating heat is formed around the lens receiving portion or the periphery of the electrode portion, and a blower fan for quickly supplying heat transferred to the heat dissipation fin to the outside is attached. It may be.

In addition, a circulation fan for circulating water in the lens accommodating part is formed in the lens accommodating part, so that sterilized water sterilized around the electrode part is quickly circulated around the lens. At this time, it is effective that the circulation fan is rotated only when power is applied to the electrode unit. By doing so, not only can the lens be cleaned more quickly, but the inside of the lens accommodating portion can be maintained aseptically.

In addition, the negative electrode support jaw fixed to the negative electrode portion and the positive electrode support jaw is fixed to the positive electrode, and the negative electrode of the power supplied from the power supply unit connected to the negative electrode support jaw, and received from the power supply And a support configured to connect the anode of the power supply with the anode support jaw. Through this, the electrode part can be easily installed in the container, and the electrode part can be easily replaced by simply attaching and detaching the electrode part to the support jaw of the support.

On the other hand, the power supply unit can be configured to apply the application direction of the power applied to the electrode in reverse. In other words, this means that the direction of the current applied to the electrode part is reversed. The anode power is applied to the first electrode part acting as the positive electrode part and the cathode power is applied to the second electrode part acting as the negative electrode part for a predetermined period. On the other hand, the negative power may be applied to the first electrode and the positive power to the second electrode. This makes it possible to prevent the solid solution from adhering to the respective electrode portions during the electrolysis process. The predetermined period may be set to a number of times from 1 to 10 times, or may be set in advance for a time such as 2 to 5 days.

In addition, the front of the outer case is formed with a receiving portion for receiving a salt solution capsule or salt lumps, even if the user does not carry a separate salt water in order to put the saline solution in the lens receiving portion, the salt solution capsule or salt in the receiving portion By carrying a lump, the user can easily wash the contact lens by making saline when the user wants to wash the contact lens.

A lens cover is rotatably formed on the outer case to open and close the lens accommodating part. At this time, a rubber packing is formed on the bottom of the lens cover to seal the lens housing, so that outside air does not enter the lens housing while the lens cover is closed. This makes it possible to keep the cleaned and sterilized contact lenses uncontaminated for a long time.

In addition, an opening / closing valve may be formed on the lens cover to selectively communicate the lens receiving portion with the outside. In the case of using the washing machine of the portable contact lens according to the present invention, it is possible to release the gas generated in the lens accommodating part to the outside by opening and closing the valve, and at the same time, the cleaning and disinfection of the contact lens are finished. In this case, the outside air penetrates into the lens housing to prevent contamination of the water and the contact lens in the lens housing.

In addition, the water may use only one or more of tap water, ground water, distilled water, and purified water, or salt water may be used to induce a more intense electrolysis reaction. If you use brine, you can use commercially available saline solution, but you can make saline by mixing the appropriate amount of salt solution according to the amount of tap water filled after filling the lens receiving part with tap water. The use of a saline solution with a concentration of about 0.7% to 1.5% compared to tap water has the advantage of minimizing damage to the fine pores formed on the surface of the contact lens, and enables faster lens cleaning through more intense electrolysis. Become. At this time, in the case of using a commercially available saline solution in terms of preventing the occurrence of side effects such as allergy due to the preservatives mixed in saline, it is more effective to use a salt mixed with water such as tap water.

On the other hand, the present invention provides a salt solution capsule, characterized in that the salt solution is packed in a container in order to prepare the brine used in the washing machine of the portable contact lens. This is to enable the user to simply wash the contact lens anywhere by simply carrying a capsule or ampoule that is as large as a nail without carrying the saline solution for cleaning the contact lens.

Here, the amount of the salt solution packaged in the capsule or ampoule in consideration of the concentration to prepare the water filled in the lens receiving portion of the brine having a concentration of 0.7% to 1.5%, preferably about 0.9% Lose. Through this, the user can simply make a salt water having a concentration corresponding to saline simply by putting a salt solution in one capsule or ampoule to the lens receiving unit for cleaning the contact lens once. At this time, the salt solution may be a saturated salt solution, but since the amount of water contained in the lens receiving portion for accommodating the contact lens is not large, it is preferable that the salt solution has an appropriate concentration in consideration of the amount of water contained in the lens receiving portion. .

On the other hand, having a container containing an amount larger than the amount of water contained in the lens receiving portion in a suitable container, by mixing more than the above-described salt solution, saturated salt solution, or salt mass in consideration of the water contained in the container About 0.9% saline can also be prepared.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, the lens cover 14 is marked (not shown), respectively, so as to distinguish the left and right sides of the contact lens, the front case so that the lens cover 14 does not open by itself even if flipped in the closed state. A locking projection 14a which is engaged with the 11 and fixed, and a sealing rubber packing 14b formed around the bottom of the lens cover 14 to prevent water in the lens receiving portion 20 from leaking outward when closed. ), An opening / closing valve 14c that opens and closes the slide lamp to block the outside air from flowing into the lens accommodating portion 20 after the sterilization and disinfection of the contact lens has been completed, and the external opening according to the movement of the opening / closing valve 14c. And a communication hole 14d for communicating the lens housing portion 20 with each other. And, the inside of the display unit 15 is formed with an LCD to indicate the operating state, the mounting ring 16a for assisting the operation button 16 is coupled to the front case 11 is fitted to the front case (11). .

The lens accommodating part 20 is formed to have a size capable of accommodating the left and right contact lenses, and therein, a circulation fan 21 formed at one side to circulate water in the lens accommodating part 20, and an electrode part ( A heat dissipation fin 22 formed at its periphery to emit heat generated at 30), a vibrator 23 formed to wash the contact lens even by ultrasonic waves, and a contact lens inside the lens accommodating part 20. And a fixing stand (not shown) having a slit for fixing. At this time, the vibrator 23 is selectively operated according to the user's setting.

The electrode part 30 is installed in one of the electrode parts 130, 230, 430 of Figures 4 to 10, or laid down, the detailed configuration will be described later.

The circuit board 40 includes a control unit 41 having a plurality of elements mounted thereon so as to be driven using power supplied from the battery 50, and an electrode unit to supply power to the positive electrode unit and the negative electrode unit of the electrode unit 30. The power supply unit 42 connected to the 30, the second power supply unit 43 connected to the vibrator 23 to supply power to the vibrator 23, and the power of the battery 50 are controlled by the controller 41. And a battery terminal 44 configured to transmit to.

Hereinafter, the operating principle of the washing machine 1 of the portable contact lens of an embodiment of the present invention will be described in detail.

The manufacturer obtains the optimum time required for cleaning the contact lens in advance, and leaves the washing machine 1 of the manufactured portable contact lens in a state in which the control unit 41 stores the memory in advance. If the user purchases such a product and wants to clean the contact lens, open the lens cover 14 and put the right contact lens in the lens receiving portion 20 marked with "R", and the lens receiving portion labeled with "L". After inserting the left contact lens into 20, the on-off valve 14c is set to the open state.

Then, the user puts some clean water such as tap water, distilled water or ground water into the lens receiving portion 20. Then, by opening the capsule (not shown) containing a high concentration of salt solution that can make the water contained in the lens receiving portion 20 of the salt water (saline) having a concentration of about 0.9%, the lens receiving portion 20 Mix with water. As a result, the water in the lens accommodating portion 20 becomes about 0.9% saline. Meanwhile, commercially available saline solution may be directly added to the lens accommodating part 20.

Then, when the user presses the operation button 16 to clean and sterilize the contact lens, the positive and negative powers of the positive electrode and the negative electrode of the electrode part 30 in the lens accommodating part 20 are respectively set in advance. Only for a while. At this time, the display unit 15 displays the message " in operation " indicating that power is being applied to the electrode unit. At this time, when no water is contained in the lens receiving portion 20, since the positive electrode portion and the negative electrode portion are spaced apart from each other, the flow of current is automatically cut off, and the water is contained in the lens receiving portion 20 Only current flows through water or brine between the positive electrode and negative electrode.

While power is applied for a predetermined time, electrolysis is actively performed in the electrode part 30 to generate a large amount of oxidants in a short time, and the circulation fan 21 in the lens accommodating part 20 rotates to rotate the lens accommodating part 20. Circulate the water inside. At the same time, the blower fan 45 around the heat dissipation fins 22 protruding around the lens accommodating part 20 is circulated to dissipate the heat generated by the electrode part 30 to the outside, so that hot air is supplied to the lower case 12. Through the vent hole (12a) of the).

Then, when the power is applied for a predetermined time and the cleaning and sterilization of the contact lens is completed by the oxidant generated from the electrode unit 30, the display unit 15 indicates that the cleaning of the contact lens is completed. Is displayed. Even when the cleaning and sterilization is completed, if the user wishes to store for several hours to several days due to taking a sleep without wearing the immediately washed contact lens, the lens cover 14 is closed and the opening / closing valve 14c is closed. It is set to the closed state to prevent outside air from penetrating into the lens receiving portion 20. Through this, the contact lens is not contaminated by external air, and thus it is possible to maintain a sterilized state for a long time.

On the other hand, after about 1 to 10 times, when the contact lens is to be cleaned using the washing machine 1 of the portable contact lens, the flow direction of the current supplied from the power supply unit 42 is applied upside down. Therefore, it is possible to automatically suppress the attachment of the solid solution to the positive electrode portion and the negative electrode portion of the electrode portion 30 through electrolysis.

In addition, the controller 41 recognizes the case where the operation button 16 is pressed once and the operation button 16 is pressed twice in succession as the signals different from each other, and the time for applying power to the electrode unit 30 is determined. You can also adjust. That is, since it takes a longer time to decompose protein than the time required for normal lens cleaning, if you want to operate a long time periodically according to the user's preference, press the operation button 16 twice for more complete cleaning And may be configured to obtain the effect of disinfection. At this time, the power supply is not always applied to all of the electrode portions 30, but is configured to apply power only to a part of the electrode portion 30, thereby obtaining effects similar to those described above.

That is, the washing machine 1 of the portable contact lens according to the embodiment of the present invention, as shown in Figure 5, the positive electrode portion 131 and the negative electrode portion 132 in the water 111 in the container 110 Leave it at a predetermined distance, and apply power from the power supply unit 120 through the power supply line 121 to induce electrolysis in the water 111, oxidation of ozone, OH radicals, etc. that appear in the reaction of the electrolysis. The principle is to sterilize bacteria or bacteria using a sieve. More specifically, the electrode unit 30 according to the exemplary embodiment of the present invention may be formed of any one of the electrode units 130, 230, and 430 of FIGS. 5 to 11.

At this time, the device 100 having the electrode portion 130, as shown in Figure 5, the container 110 for receiving the water 111, and the electrode portion fixed to the bottom surface of the container 110 And a power supply unit 130 for supplying power to the electrode unit 130.

The power supply unit 130 may be an external AC power source, a DC power source converted from AC power source, or a DC power source supplied to a battery. The negative power line 121 from the power supply 130 is connected to the negative electrode plate 131, and the positive power line 122 from the power supply 130 is connected to the positive electrode plate 132.

6 to 8, the negative electrode plate 131 having a plurality of negative electrode protrusions 131a formed on a surface thereof, and the positive electrode plate having a plurality of positive electrode protrusions 132a formed on a surface thereof, as illustrated in FIGS. 6 to 8. 132, the negative electrode plate 131 and the positive electrode plate 132 is fixed to the bottom of the container 110, the support 133 and the fixing hole 133a of the support 133 through the container It is configured to include a fixing screw 134 for fixing to the bottom surface of (110).

Here, the negative electrode plate 131 and the positive electrode plate 132 are spaced apart by a predetermined interval d2 and fixed to the support 132, spaced apart by a predetermined interval d1 and faced to each other so as to face each other. Conical cathode projections 131a and anode projections 132a protruding from each other are provided, and the electric charges applied to the electrode plates 131 and 132 are concentrated on the tip portions B of the projections 131a and 132a. Therefore, the electrolysis of water between the cathode protrusion 131a and the anode protrusion 132 can be further promoted as compared with the case where the same power is applied.

In addition, the cathode protrusion 131a and the anode protrusion 132a are thickly plated with platinum so that active electrolysis occurs.

And, as shown in Fig. 7, the support 133 is connected to the negative electrode plate connection slot 1331, which is recessed to insert and fix the negative electrode plate 131, and the positive electrode plate connection to be recessed to sandwich the positive electrode plate 132. Slot 1332 is formed. 6, the cathode power line 121 is connected to the negative electrode plate connection slot 1331, and the anode power line 122 is connected to the positive electrode plate connection slot 1332 inside the support 133. It is configured to be connected, so as to simply insert the electrode plate (131,132) in the slots (1331, 1332) of the support 133, the power is configured to be supplied to the electrode plate (131,132).

 Therefore, when the platinum of the electrode plates 131 and 132 is consumed, the replacement is completed by simply removing the consumed electrode plates 131 and 132 from the slots 1331 and 1332 and inserting the new electrode plates 131 and 132 into the slots. Therefore, the cleaner 100 of the portable contact lens configured as described above can be used semi-permanently.

Hereinafter, the operating principle of the device 100 including the electrode portion will be described in detail.

When the user wants to clean and disinfect the contact lens using the apparatus 100, the tap water 111 is filled in the container 100, and when the power is applied from the power supply unit 120, the power supply unit 120 is applied. Power is supplied from the negative electrode plate connection slot 1331 and the positive electrode plate connection slot 1332 of the support 133 to the power supply. Then, through each of the connection slots 1331 and 1332, the negative power is supplied to the negative electrode plate 131 and the positive power is supplied to the positive electrode plate 132. At this time, power is applied to the negative electrode plate 131 and the positive electrode plate 132, but charges are concentrated on the negative electrode protrusions 131 a and the positive electrode protrusions 132 a formed on opposite surfaces of the respective electrode plates 131 and 132. . Therefore, electrolysis occurs violently between each of the protrusions 131a and 132a, and foreign substances, proteins, and bacteria in which oxidants such as ozone, hydrogen peroxide, HOCl, and OH radicals generated in a large amount through intense electrolysis are attached to the contact lens. And bacteria can be cleaned and sterilized in a short time.

Since the apparatus 100 needs only to install the electrode plates 131 and 132 having the projections 131a and 132a formed in the container, the size of the washing machine 100 of the portable contact lens can be configured to be small enough to be portable.
