Abstract

PURPOSE:To prevent a contact lens from flawing in cleaning by providing a liquid processing container with a lower liquid hole which is open slantingly downward to a lens storage chamber and supplies upward agitating liquid into the lens storage chamber. CONSTITUTION:The lower water hole 83c of the liquid processing container 80 is open slantingly downward in an area GG, so the upward stirring water flow passes through the lower water hole 83c from slantingly below the lens storage chamber 83, i.e. as shown by an arrow P1 to enter the lens storage chamber 83. Consequently, the contact lens W in the lens storage chamber 83 floats properly in the lens storage chamber 83 separately from the wall surface of the lens storage chamber 83 and is cleaned effectively. Consequently, even when a hard lens which is easy to flaw is cleaned, its flawing is suppressed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a contact lens cleaning device that cleans contact lenses by generating an agitated liquid flow.

[Prior Art] When wearing contact lenses, the general practice is to support the contact lens with the palm of the hand or fingertips, drop cleaning water onto the surface of the contact lens, and clean the contact lens by touching it with your fingertips. This allows the surface of the contact lens (
Removes dirt, especially fat contained in tear fluid.

In order to effectively perform such cleaning, the applicant has recently developed a cleaning device that operates an agitator placed in the cleaning chamber to generate an agitated water stream and cleans contact lenses with the agitated stream. 63-134111@〉.

[Problem to be solved by the invention] The present invention was made as part of the development of the above-mentioned device, and its purpose is to effectively float contact lenses in a lens storage chamber, thereby making it possible to further improve contact lenses. To provide a contact lens cleaning device that can effectively clean contact lenses and prevent damage to contact lenses during cleaning.

[Means for Solving the Problem] In the process of developing a contact lens cleaning device, the present inventor discovered that by applying a liquid flow to the contact lens obliquely from below, the contact lens can be effectively floated in the lens storage chamber. The inventors have discovered that it is possible to more effectively clean the lens and to suppress the amount of damage to the lens during cleaning, and based on this discovery, the present invention has been completed. .

The contact lens cleaning device of the present invention includes a cleaning chamber ζ having a container chamber, a solution processing container arranged in parallel with a lens storage chamber for storing lenses, and a solution processing container disposed below the solution processing container. and a stirring section that generates an upward stirring liquid flow that rises toward the container chamber. It has an appropriate number of liquid holes, and at least one of the liquid holes is a lower hole that opens diagonally downward with respect to the lens storage chamber and allows the upward stirring liquid flow to flow into the lens storage chamber. It is.

The cleaning room is a room where contact lenses are cleaned. The cleaning chamber can be equipped with a heating unit that heats the liquid in the cleaning chamber 1 to disinfect the lenses. The planar shape of the container chamber in the cleaning chamber is two circular planar chambers arranged side by side so that a total of two lenses for the right eye and the left eye can be housed side by side. It can also be referred to as an elliptical-shaped chamber or an approximately-shaped chamber.

The liquid processing container is provided with a tank 1 and a lens storage chamber for storing lenses. The liquid processing container is removably or fixedly disposed in the container chamber.

The liquid processing container has an appropriate number of liquid holes that penetrate the side wall portion that partitions the lens storage chamber and communicate the inside of the lens storage chamber with the outside. The liquid hole is a hole through which the agitated liquid flow flows into the lens storage chamber. It is desirable that the opening area of the liquid hole and the direction of passage of the liquid hole can be selected appropriately, or that the liquid hole does not come out of the contact lens or the liquid processing container. Here, at least one liquid hole is a dipping hole that opens diagonally downward. In this case, since the rising stirring liquid flow flows upward, it is necessary to set the lower hole at a position facing this flow. The angle of opening diagonally downward with respect to the vertical line can be appropriately selected depending on the type of accompanying part, the degree of stirring, the type of soft type or hard type contact lens, etc.

Note that the liquid processing container may be of a type in which lens storage chambers are formed separately on the left and right sides, a type in which lens storage chambers are formed separately on the top and bottom, or a type in which a single lens storage chamber is provided depending on the case.

The trailing section is disposed below the liquid processing container and generates an upward agitated liquid flow that rises toward the container chamber. As the trailing section, for example, a vane system in which a trailing blade is rotated to generate a liquid flow (rotation speed, e.g., 3000 to 9000 rpm) is used.
Alternatively, it is possible to adopt a method of generating a stirring liquid flow using a liquid jetted out from a nosulkara.

[Function] The accompanying part operates while a soft type or hard type contact lens is stored in the lens storage chamber of the liquid processing container and a liquid is supplied to the cleaning chamber. Then, the stirred liquid flow becomes an upward stirred liquid flow that rises toward the container chamber, and the liquid flow flows into the lens storage chamber from the liquid hole of the liquid processing container, and the contact lenses in the lens storage chamber are cleaned. At this time, the immersion hole of the liquid processing container opens diagonally downward, so
The upward stirring liquid flow flows into the lens storage chamber from diagonally below the lens storage chamber. Therefore, the contact lenses in the lens storage chamber come to float appropriately, and the contact lenses are effectively cleaned.

Next, the liquid processing container 80 will be explained with reference to FIGS. 6 to 10. FIG. 8 is a diagram along the Y--Y line of FIG. 6. The liquid processing container 80 is a resin container that accommodates the contact lens W, and is formed by a container body 81 and a lid 82. In the container body 81, two lens storage chambers 83 having an opening on the upper surface are formed side by side on the left and right. Lens storage room 8
A small circular water hole 83a serving as a liquid hole is formed in the bottom wall of No. 3 so as to penetrate in the vertical direction. As shown in FIG. 10, the ring-shaped lens storage chamber 83 has five thick side wall portions 83 which are defined as a zone, a zone GG, and a zone FF in the clockwise direction.

In the area HH of the side wall part 83, a large number of upper water holes 83b in the form of slits 1 as liquid holes are formed in the radial direction, and further in the area GG of the side wall part 83, as lower liquid holes. A suitable number of sewage holes 83c are formed in the recutting direction, and a large number of slit-like water holes 83b as liquid holes are formed in the radial direction in the region FF of the side wall portion 83. 8th
As shown in the figure, the water supply hole 83b penetrates laterally,
It does not penetrate diagonally downward. Further, as shown in FIG. 8, a sewage hole 83 C4J penetrates diagonally downward.

At the center of the container body 81, a long rod-shaped protrusion 85, which also serves as a legitimate child to be grasped with the fingertips, is formed with an upward C curve, and an escape hole 85G is formed near the protrusion 85. Note that the escape hole 85C is for letting water escape to the trailing blade 15 side.

On the other hand, m82 is attached to the upper opening of the lens storage chamber 83 of the container body 81 to close the lens storage chamber 83. As shown in FIG. 7, a holding hole 82e for holding the protruding portion 685 is formed in m82, and two thick fitting portions 86 are formed in a bulging manner. The portion 86 is adapted to fit into the lens storage chamber 83 of the container body 81. A small circular water hole 86a serving as a liquid hole is formed in the fitting part 86 to penetrate in the vertical direction, and a regulating protrusion 86b for regulating the position of the contact lens W is provided at the center of the bottom surface of each fitting part 86. It is formed. As shown in FIG. 10, when the liquid processing container 80 is installed in the container chamber 5a of the cleaning chamber 5, a gap 5s through which water flows is formed between the inner wall surface 5h of the container chamber 5a and the liquid processing container 80. has been done.

Note that a protrusion 87 is formed on the container body 81, and m82
A protrusion 88 is formed in the. Here, if the left and right lens storage chambers 83 are placed in the wrong direction, the protrusions 87 and 88 will interfere with each other, making it impossible to attach the lid 82 to the container body 81 even if m82 is attempted to be attached to the container body 81.

(How to use the example) Next, how to use the device according to this example 7 The effects will be explained separately in (A) to (D).

(A> Preparation First, rotate the rotation M3 to open the cleaning chamber 5, drop several drops of concentrated cleaning liquid into the cleaning chamber 5, and place the liquid processing container 80 containing the contact lens W in the lens storage chamber 83. It is placed on the step 5 of the cleaning chamber 5 and stored in the container chamber 5a, and the rotation M3 is closed. It engages with the projection 2 to be engaged, and the rotary lid 3 is locked.Also, the water tank 30 storing water is lowered in the direction of arrow D1, that is, downward, and attached to the water tank mounting portion 2g, as shown in FIG. As shown, the valve 39 of the water tank 30 is brought into contact with the protrusion 26 and pushed up to open the water supply port 37.

(B)) When an unillustrated switch is operated in the above-mentioned state, the water supply valve 22 is opened for a predetermined time using a timer.

Then, the water in the tank chamber 30d of the water supply tank 30 is supplied into the cleaning chamber 85 through the passage 25a under pressure due to its water head pressure. Therefore, the inside of the cleaning chamber 5 is swirled up to the reference water level, which is almost full of water. This dilutes the concentrated cleaning solution.

Note that when water is supplied, the atmosphere release valve 69 is turned on and the hole 6 is closed.
Since B is opened, the cleaning chamber 5 is communicated with the outside air via the chamber 46, the passage 47, and the passage 70a, and water can be smoothly supplied. When the water supply is finished, the motor 9 rotates for a predetermined period of time, the motor shaft 9a and the rotating shaft 3 rotate, and the stirring blade 15 moves into the cleaning chamber 5.
It rotates at a high speed of about 800 rpm. As a result, the water in the stirring chamber 5b of the cleaning chamber 5 becomes an accompanying water flow that has an upward tendency to rise while swirling toward the container chamber 5a. The accompanying water flow flows into the lens storage chamber 83 through the water holes 83a and other C of the liquid processing container 80, and the contact lenses W in the lens storage chamber 83 are cleaned.

At this time, as shown in FIG.
In other words, it rotates in the clockwise direction, so the stirring chamber 5b
The accompanying water flow inside also rotates clockwise.

Therefore, the accompanying water flow transferred from the sliding chamber 5b to the container chamber 5a flows in the direction of arrow R2 within the gap 5S9 along the inner wall surface 5h of the container chamber 5a. The accompanying water flow flowing in the two directions of the arrow holes within the gap 5S is the water hole 83b and the sewer hole 83.
It flows into the lens storage chamber 83 from G. In region GG, which is not shown in Fig. 10, the associated water flow tends to be upward, and in region F, the associated water flow tends to be downward. JIC conjectures that this is because the region F is located near the stirring blade 15, which is the source, and the region F is located in the direction a3 around the hour 11 and is far from the stirring blade 15, which is the accompanying source.

In this regard, in this embodiment, the sewage hole 83C of the liquid processing container 80 is located in the region GG and opens diagonally downward, so that the rising water flow is directed from diagonally downward of the lens storage chamber 83, that is, in the direction of arrow P1 shown in FIG. It flows into the lens storage chamber 83 through the sewage hole 83C.

Therefore, the contact lenses W in the lens storage chamber 83 are separated from the wall surface of the lens storage chamber 83 and float appropriately within the lens storage chamber 83, and the contact lenses W are effectively cleaned.

It is presumed that the direction of the effluent flow in the lens housing chamber 83 during cleaning is as indicated by arrows R4, R5, and R6 shown in FIG. Since microscopic air bubbles are included in the water stream during cleaning, the removal of dirt from the contact lens W is effective.

During cleaning, the water supply valve 22, drain valve 23, and atmosphere release valve 69 are closed, so that the cleaning chamber 5 is sealed.

When the cleaning is finished and the motor 9 stops, the drain valve 2
3 or open works. As a result, as can be understood from FIG.
2.

(C) Rinsing: Next, the water supply valve 22 is opened for a predetermined period of time, so water in the water supply tank 30 is supplied into the cleaning chamber 5 at its water head pressure. In this state, the motor 9 rotates for a predetermined period of time, and as a result, the stirring blade 15 rotates in the clockwise direction of arrow R1 (not shown in FIGS. 9 and 10) in the same manner as described above. An accompanying water flow is generated in the circular direction with
Rinsing of the tank ~ 2 lunes W is performed. At this time, as described above, the sewage hole 83C of the liquid processing container 80 opens obliquely downward, so that the upward accompanying water flow flows into the lens accommodating chamber 83 from obliquely below the lens accommodating chamber 83 via the sewage hole 83G. Therefore, the contact lens W in the lens storage chamber 83 comes to float appropriately, and the contact lens W is effectively rinsed.

When the cleaning is completed, the river water valve 23 is opened and the water in the cleaning chamber 5 is discharged into the drain tank 42. In addition, at the time of washing, the water supply valve 22, the drain valve 23, and the popular release valve 69 are closed, so that the cleaning chamber 5 is in a sealed state.

(D> Disinfection) Next, the water supply valve 22 is opened for a predetermined period of time, so that the water in the water supply tank 30 is supplied to the cleaning chamber 5 at the head pressure. Then, the water in the cleaning chamber 5 is heated, and the contact lens W is sterilized by boiling θ11.

Note that when using a contact mill lens, open the rotating lid 3 and take out the liquid processing container 82O from the cleaning chamber 5, then remove the lid 82 from the container body 81, and remove the tank 1 to lens inside. Just take out the W.

During disinfection, the water supply valve 22, drain valve 23, and atmosphere release valve 69 are closed, so that the cleaning chamber 5 is kept in a sealed state to prevent germs, dust, etc. from entering.

Furthermore, when the internal pressure of the cleaning chamber 5 increases abnormally during the 11th boiling period, the check valve 50 is activated and the through hole 3C is opened -υ, so that an abnormal increase in pressure inside the cleaning chamber can be avoided via the relief vent 8. .

By the way, when performing boiling sterilization, the cleaning chamber 5 is normally kept in a sealed state to prevent the intrusion of germs, dust, etc. Therefore, as the inside of the cleaning chamber 5 cools down after sterilization by boiling, the inside of the cleaning chamber 5 becomes in a negative pressure state, and due to the influence of atmospheric pressure, the rotary lid 3
There is a3 that cannot be released. In this case, if the button 56 of the rotary lid 3 is pressed, the operating shaft portion 56a of the button 56 is pressed.
presses the lock plate 57, which causes the relock plays 1 to 57 to rotate, and the operation section 5 of 57 to the lock play 1.
7C or press check valve 55. As a result, the flange portion 55b and the seal portion 55G are lowered, and the communication passage 354 is opened. As a result, the outside air and the inside of the cleaning chamber 5 are communicated with each other, and the negative pressure inside the cleaning chamber 5 is released.

(Effects of the Example) As explained above, in this example, the contact mill lens W is cleaned and cleaned using a high-speed accompanying water stream, so the cleaning is performed using an ultrasonic cleaning device and an elastic pad. [Compared to a conventional cleaning device] It is possible to efficiently clean the dirt deposited on the surfaces of the tank 1 to the lens W.

In particular, in this embodiment, the sewage hole 80G of the liquid processing container 80 opens diagonally downward, so that the upward stirring water flow flows into the lens storage chamber 83 from diagonally below the lens storage chamber 83. Therefore, the tank 1 to the lens W in the lens storage chamber 83 float appropriately, and the contact lens W is effectively cleaned and rinsed.

Furthermore, since the tank 1 Helen's W in the lens storage chamber 83 floats appropriately, the contact lenses are away from the wall that partitions the lens storage chamber 83, and therefore, damage to the contact lens 1 Helen's W is avoided as much as possible.

Further, in this embodiment, the water supply tank 30 is a tamp for washing water and a sailor, and only one tank is required, thereby reducing the number of tanks. Therefore, only one passage 25a of the pipe 25 is required for communicating the cleaning chamber 5 and the water supply tank 30. Further, the number of electromagnetic valves for supplying water to the cleaning chamber 5 is only 22.1 water supply valves.

Therefore, it is advantageous in terms of space. Moreover]
If you wish to change the type, material, or concentration of contact lens cleaning, you can change the dilution level or type of concentrated cleaning water to change the concentration and type of water used to clean contact lenses. It is also possible to change the material depending on the degree of dirt on the contact lens and the type of lens.

[Effects of the Invention] According to the tank 1 to lens cleaning device of the present invention, the liquid flow flows into the lens storage chamber from the liquid hole of the liquid processing container, and the contact lenses in the lens storage chamber are cleaned. Since the immersion hole of the processing container opens diagonally downward, the rising agitating water flow flows into the lens storage chamber from diagonally below the lens storage chamber.Therefore, the contact lenses in the lens storage chamber float appropriately. Contact lenses are effectively cleaned.

Moreover, damage to contact lenses during cleaning can be suppressed. Therefore, even if hard lenses that are easily scratched are cleaned, it is advantageous to prevent scratches from occurring.
