Description

A centrifugal force use portable soft contact lens clean machine

The present invention relates to an apparatus for cleaning a lens using centrifugal force at the same time as disinfecting drugs by ultrasonic and lens cleaner. Although the world's population of contact lenses is rapidly increasing to about 2 million people (Hankook Ilbo 98.10.15), there are no devices that can remove proteins and foreign substances from contact lenses. Depending on the liquid, the lens is washed by hand. As a result, the lens was damaged during lens cleaning (lens tearing, scratching, falling off, etc.) and protein, fat and dirt attached to the microscopic oxygen holes of the lens were not removed, causing various eye diseases.

For this purpose, commercially available ultrasonic lens cleaners (Utility Model No. 121627, Invention Patent No. 98-39695, Design Registration No. 181465, International Invention Patent Application No. 091456520, International Invention Patent Application No. 370854) While 125,000 vibrations per second have the advantage of removing debris by repeating the process of decomposition, fusion, shrinkage, and boosting of saline solution, it is impossible to perform three or more ultrasonic cleanings in succession, and 125.000 times per second to the soft lens by frequent ultrasonic cleaning. Vibration causes surface damage, resulting in shortened or torn lenses.

In addition, only the ultrasonic cleaner is expensive and difficult to carry, because the power supply must be available through the power adapter to operate. In addition, if you want to purchase a portable cleaning bath for an ultrasonic cleaner, the cost is one third of the total cost.

In addition, the development of a multi-purpose multi-lens cleaning solution that enables cleaning, rinsing, preservation, and protein removal at once by putting the soft lens cleaning solution in the lens case and storing the soft lens has a high recognition that there is no need for ultrasonic cleaning. High, but short lens life or multiple repetitive cleaning cycles are an obstacle to the use of ultrasonic lens cleaners.

Therefore, the main object of the present invention is to perform a plurality of lens cleaning using centrifugal force by the rotational force of the AC-type AC motor (1a) when the residual foreign matter still remains on the surface after the ultrasonic cleaning once, so that several surfaces without damage It is to make the lens cleaning more clean by making it possible to wash once.

In addition, since the upper right cap (2a) of the sphere is rotated open and closed, it is designed for easy lens insertion and can be cleaned by simply pouring the multi-purpose multi-cleaning solution into the existing lens case and soaking the lens. The washer was used to increase protein removal efficiency.

In the case of using centrifugal force generated during washing, the column (2d) of the circular filter (2b) has a high elasticity similar to that of bamboo, so the centrifugal force generated by the AC motor is attached to the upper right cap (2a) of the sphere. (2b) adds rolling (up and down) and pitching (left and right) movements to improve the efficiency of lens cleaning.The lenses washed like this do not have a burden even if worn for a long time and the incidence of various eye diseases due to lens failure It is effective to suppress the maximum.

A feature of the portable soft lens cleaner according to the present invention to achieve the above object is to enable the clock (3a) to rotate clockwise and counterclockwise at regular intervals.

That is, because the lens cleaning liquid rotating in the sphere 2 is temporarily fixed to the inner surface of the sphere 2 when the centrifugal force is applied in one direction, the effect of washing cannot be expected. In addition, the high elastic female threaded support (2d) of the circular opening (2b) inside the spherical cylinder (2b) is resilient to move the rolling (up and down) and pitching (left and right) to the lens, thereby rotating the AC motor (1a). In addition to the centrifugal force by the lens cleaning effect to raise the level a step further has been configured to allow efficient cleaning.

Hereinafter, the configuration and effect of the invention by the accompanying drawings, preferred embodiments according to the present invention will be described in detail.

Figure 1 is a side view of the soft lens cleaner according to the present invention, as shown in the structure that reminds the desk fan, it can be divided into three parts. When the upright rod-shaped body (1) is combined with a sphere (2) which receives rotational force by the shaft of the AC-type AC motor (1a) as an axis, and the centrifugal force is applied thereto, the safety and center of gravity of the soft lens cleaner are placed on the lower part. It has a wide bottom 3 for placing, and it is comprised so that operation of a soft lens washing machine is easy and easy using the automatic control apparatus (the operation / stop button 3a and the timer 3b and the intensity 3c).

The upright rod-shaped main body 1 is composed of an AC-type AC motor 1a, an upper body terminal 1b, a lower terminal 1c, and a battery inlet cap 3e, and alternating current to give a rotational force to the bulb 2. The type AC motor 1a is located above the upright rod-shaped main body 1. If the battery insertion cap 3e is opened on the upright bar-shaped main body 1 having the upper terminal 1b and the lower terminal 1c attached thereto, two 1.5v batteries can be inserted into the secondary power supply. In addition, a motor electronic control unit and an ultrasonic wave generator 1d for automatically controlling generation and stop, operation, timer, and the like of the ultrasonic wave are provided above the upper terminal 1b.

In the above-described sphere (2) constitutes a vibrator (2h) for ultrasonic cleaning and the rubber packing (2c) is inserted in order to prevent leakage in the upper right portion of the sphere required when giving centrifugal force, the circular filter (2b) is a sphere It is attached to the upper right cap (2a) and has a configuration of high elastic female screw strut (2f) and male thread strut (2d) to facilitate the replacement of the circular filter.

Also, the top row of rows 2a has a concave groove 2e to facilitate opening and closing. In order to insert the soft lens, first, the upper right cap 2a of the spherical opening and closing method is turned to the right using a concave groove. Then, it is possible to separate, and in the center of the open circular filter 2b, the circular cotton yarn 2i separates the left and right eyes, and the locking jaw 2g is attached by a small spring, so that the lens is inserted in the open circular filter during rotation. (2d) is opened to prevent damage to the surface of the protruding lens, and the circular filter post (2d) has a high elasticity to give the circular filter (2h) the operation of rolling (up and down) and pitching (left and right) By constructing a soft plastic material, the high resilient female-threaded support post 2d is moved up, down, left and right by the centrifugal force of the sphere 2, and has a more efficient cleaning effect on the soft lens.

In the above stand (3) gives the center of gravity of the soft lens cleaner at the lower end to give a rotational force to the sphere to prevent the fall and prevent the automatic control device (action / stop button (3ab), timer (3c), intensity (3d)] It is easy to operate by using and has a configuration to supply secondary power through the battery insertion hole on the lower part.

With the above-described configuration of the present invention, the ball is rotated by the AC-type AC motor, and the centrifugal force generated thereby creates a strong water current. In addition, the highly resilient strut adds the rolling (up and down) and pitching (left and right) movements to the circular filter, so that foreign substances (cosmetics, eyeballs, ink) of the protein and lens can be removed cleanly, The burden is low, and the field of view is kept fresh.

In addition, if there is a foreign substance on the surface of the lens even after ultrasonic cleaning, repeated ultrasonic cleaning may shorten the lens life itself or damage the surface. Therefore, when repeated cleaning after ultrasonic cleaning is necessary, use centrifugal force washing by AC motor. By removing foreign substances in the lens, it is possible to reduce the burden of the soft lens on the use of ultrasonic waves, to prolong the life, and to prevent the surface damage of the lens.

In addition, by using a portable soft lens using centrifugal force, it is possible to solve the problem of clogging the oxygen permeation hole due to the surface damage or protein of the lens, which occurs when washing by hand. It has the effect of reducing the incidence of the disease.
