Abstract

PURPOSE:To wash a contact lens and to sterilize it at a high temperature by incorporating an oscillation circuit member having an ultrasonic oscillation circuit which supplies the output to an oscillator in a washer body and providing a heater, to which power supply is automatically stopped after a certain time, under the washing vessel. CONSTITUTION:When a contact lens 6 is put in a washing vessel 5, it is held in a cylindrical holding part of a storage case 8 and is covered with a cap P. Washing liquid is charged in the washing vessel 5 until the storage case 8 is completely sunk in the washing liquid; and after washing, a timer switch 7 is switched to the side of a heater 9 to supply power to the heater 9 attached to the outside wall of the washing vessel 5 to raise the temperature of the washing liquid to boil and sterilize the contact lens 6. Since power supply to the heater 9 is automatically stopped after boiling for a certain time, the contact lens is prevented from being damaged by heating without liquid. Thus, the contact lens is surely washed in a short time by ultrasonic waves.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cleaning device for cleaning contact lenses.

BACKGROUND ART Conventionally, contact lenses have been cleaned by hand using a special cleaning agent, or by soaking them in a cleaning solution and rinsing them with water.

Problems to be Solved by the Invention However, with long-term use, secretions in lacrimal fluid, especially proteins, adhere to the surface of the lens, reducing the performance of the lens. Contact lenses and soft contact lenses have proteins attached to their permeable pores that cannot be removed with normal cleaning solutions. To do this, we have to use an enzyme-based protein remover and soak the lens in the solution for 3 to 10 hours to remove the protein and prevent the lens from becoming cloudy, a process that must be carried out once a week. Must be.

In addition, in the case of soft lenses, secretions inside the eyes and dirt from handling tend to adhere to the lenses, which can lead to the growth of bacteria and mold, so after cleaning, sterilize them by boiling them in a pot or pot every day. There is a problem in that it requires double cleaning and cleaning. Also, as shown in Figure 4, ultrasonic cleaners are commercially available, but they are large and difficult to use.
The disadvantage that the aforementioned disinfection cannot be performed remains.

Means for Solving the Problem The present invention provides a cleaning container inside the main body that protrudes from the upper surface,
A vibrator that vibrates at high frequency in contact with the bottom of the cleaning container is disposed, an oscillation circuit member having an oscillation circuit is built in the main body, and the output of the oscillation circuit is supplied to the vibrator, and the vibration of the cleaning container is It is equipped with a heater at the bottom that automatically stops energizing after a certain period of time.

Effect The effect of the technical means of the present invention is that the vibrator vibrated at high frequency by the oscillation circuit transmits ultrasonic waves to the cleaning container, and the ultrasonic vibrations are transmitted to the contact lens through the liquid filled in the cleaning container, thereby removing dirt. drop.

Thereafter, the temperature of the cleaning container is raised by the heating element, and the contact lenses are sterilized at high temperature.

Embodiment FIG. 1 is a cross-sectional view of one embodiment of the washing machine of the present invention, FIG. 2 is a perspective view of the same, and FIG. 3 is a perspective view of a partially sectional storage case.

The structure of the cleaning device of the present invention will be explained.

In Figures 1, 2, and 3, the main body case (1
) contains an annular recess ID provided inside the upper part of the vibrator support IC, in which a vibrator (3) that vibrates with the high frequency voltage generated by the oscillation circuit member (2) projects inwardly at the bottom IA of the main body. It is attached via a vibration isolator (4) fitted to the.

The transducer support IC is attached to the main body cover IB of the main body case (1).
A rectangular hole is drilled directly above the hole, and an annular locking part α0 is placed on the top surface.
) is placed on the vibrator (3) fitted to the vibration isolator (4) of the vibrator support IC. Ultrasonic vibrations are transmitted to the cleaning container (5) by the vibrator (3). (11) is a ring-shaped thermal insulation material.

A heater (9) is freely installed at the bottom of the cleaning container (5) and is stopped after a certain period of time.

When cleaning contact lenses (6), use a cleaning container (5).
) In the present invention, the object to be cleaned is a contact lens (
6) Add cleaning solution until it is completely submerged in the liquid. Then, turn the timer switch (7) to set the time and turn on the switch.

The contact lens (6) can remove dirt stuck to itself by ultrasonic vibration. The present invention is economical as it can utilize a storage case (8). In addition, when putting the contact lenses (6) into the cleaning container (5), as shown in Fig. 3, there is usually a storage case (8) for storing the contact lenses (6), a cylinder for holding the K contact lenses (6), and a cylinder for holding the contact lenses (6). Store it in the shape holding part and cover it with the cap P. Pour the cleaning solution into the cleaning container °5 until the storage case (8) is completely submerged in the cleaning solution. When cleaning is completed, the timer switch (7) is switched to the heater (9), and the heater (9) attached to the outer wall of the cleaning container (5) is energized, heating the cleaning container (5) and discharging the cleaning liquid. The temperature of the contact lens (6) increases, and the contact lens (6) can be sterilized by boiling.

After boiling for a certain period of time, the power supply to the heater (9) is automatically stopped, so there is no damage to the contact lenses due to dry boiling.

Contact lenses (6) are placed directly into the cleaning solution using a cleaning device (5).
can be stored without touching it.

Effects of the Invention According to the present invention, contact lenses can be cleaned using ultrasonic waves in a short time and reliably. Furthermore, since the cleaning container can be made smaller, a smaller amount of cleaning liquid can be used. Because the vibration energy can be controlled specifically for contact lenses, there is no chance of contact lenses breaking, which is an advantage that regular ultrasonic cleaners do not have. Also,
Since cleaning and boiling sterilization can be performed with the same equipment, it is very convenient and saves time and effort, and the structure of the present invention also prevents damage to the lens due to dry cleaning.
