Description

Technical Field

[0001] The invention relates to the technical field of contact lens cleaning, in particular to a household device for replacing contact lens liquid and an operating method thereof. Background Art

[0002] Many of the contact lens cleaning devices currently available on the market are semi-automatic cleaning devices, and are almost all aimed at deep cleaning of contact lenses, so human intervention is necessary. However, in real life, since contact lens users may have multiple pairs of glasses, or the frequency of contact lens wear is not high, they often forget to change the contact lens solution. Failure to replace the contact lens solution in time will provide conditions for the growth of bacteria, and it is likely that the contact lenses will no longer be suitable for continued wear. At the same time, due to the existence of business trips, travel and other events, the probability of not being able to replace the contact lens solution in time and regularly will greatly increase. Secondly, due to the existence of human initiative, the cleaning effect and cleaning efficiency may not meet certain standards.

[0003] Traditional semi-automatic contact lens cleaning usually uses ultrasonic waves or rotating liquids. However, if the liquid is not drained out in time during the cleaning process, the cleaning effect is limited. If the liquid is not replenished in time, the contact lenses will dry out and lose their effectiveness.

[0004] Traditional contact lens cases vary widely, but most are of the twist-off cap type. These different sizes and dimensions make it extremely difficult to automatically replace contact lens solution.

[0005] There are still few cases that are suitable for automatic timed cleaning of contact lenses. In real life, a cheap and reliable device for automatic timed cleaning and replacement of contact lens solution is in great demand. Summary of the invention

[0046] There are two slide rails, which are arranged in parallel, and the ends of the two slide rails are arranged toward the opening.

[0049] The operating method of the device for replacing contact lens liquid at home is as follows: the driving mechanism drives the mounting plate and the glasses box to translate between the liquid discharge position, the liquid filling position and the storage position through the front and rear translation mechanism; when the glasses box is at the storage position, the upper cover and the lower cover seal the glasses box; when the glasses box is at the liquid filling position, the upper cover is opened, the lower cover is sealed, and the automatic liquid filling mechanism fills the glasses box with contact lens liquid; when the glasses box is at the liquid discharge position, the upper cover and the lower cover are both opened, and the contact lens liquid is discharged; the glasses box reciprocates within the travel range of the front and rear telescopic mechanism, the lower cover is sealed, and the contact lenses are cleaned. Timed liquid discharge, timed liquid replacement, and timed cleaning are realized through a single-chip microcomputer.

[0050] Working process: At the beginning, the first servo rotates and the second slider is in the storage position. The first servo is powered on to maintain this position. At this time, the spring is in a compressed state, the upper opening is tightly matched with the upper cover, the lower opening is tightly matched with the lower cover, and the glasses box is sealed. The single-chip control system provides a timing module, and after 24 hours, a control signal is sent to the system. The first servo starts to rotate, and the first slider is in the drainage position. At this time, the upper and lower openings of the glasses box are opened at the same time. Due to the filter screen made of special materials in the contact lens box, the liquid is discharged from the contact lens box, and the contact lenses are still in the box. The spring returns to its original length, and the lower cover extends due to the combined action of the spring and the first slider in conjunction with the slide rail.

[0051] The first servo starts to rotate, the mounting plate is in the liquid adding position, the spring is in a compressed state, and the lower opening is closed due to the joint action of the spring and the first slider and the slide rail, which are tightly connected to the lower cover. At this time, the upper cover is still in an open state. Then the second servo starts to rotate a certain angle, and through the gear rack meshing transmission, it drives the block to withdraw a small section from the connecting channel. The connecting channel is opened a little, and the liquid slowly flows down the pipeline and falls into the glasses box with the upper opening in the open state. The amount of liquid in the contact lens is controlled through testing to complete the liquid injection.

[0052] The second servo restores the angle, the block is pushed into the communication channel, the communication channel of the reservoir is closed, and the liquid flow in the conduit is drained. The first servo starts to rotate intermittently, and the second slider moves back and forth between the liquid adding position and the storage position, thereby cleaning the contact lens. After 5 to 6 times back and forth, it returns to the liquid draining position to drain the contact lens liquid.

[0053] Repeat the above-mentioned draining, filling, cleaning and draining process 3 to 4 times. Return to the position to add liquid and complete the filling process again. The first servo turns back to the initial position, and the second slider moves to the position storage position. At this time, the upper and lower openings of the contact lens box are closed at the same time, the spring is in a compressed state, and the contact lens box is sealed. The first servo maintains the position and the work is completed.

[0054] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
