2. Description of the Prior Art
People with myopic problems usually wear glasses with frames in order to obtain normal or enough eyesight to maintain their normal vision performances. Recently, the glasses with frames are widely replaced by contact lenses under beauty consideration. However, corneas of users may suffer from anoxia that will cause injury to the corneas when people continuously wear contact lenses for a long period of time. Thereby, after wearing contact lenses for a certain period of time, people have to take off, wash, and clean their contact lenses for the next use.
Prior to soaking the contact lenses, manufacturers usually advise users to rub their contact lenses by their fingers in order to loosen foreign debris. The most common way to clean contact lenses is to put a pair of contact lenses into two containers of a contact lens case that is filled with clean solution and rub the contact lenses with fingers. Thereby, the dust, deposited proteins, mucus, oil stain, or other dirty things can be removed therefrom and the oxygen permeability of the contact lenses can be maintained. However, the cleaning way mentioned above may fail to work effectively if the fingers used to rub the contact lenses are unclean. Besides, the cleaning process is also time-consuming. Thereby, vibration is introduced as an alternative to the use of finger rubbing.
Different types of cleaning devices for contact lenses are invented recently and the contact lenses put in these cleaning devices can be shaken by hands, vibrated by motors, or shaken by ultrasonic agitation. When people clean their contact lenses by soaking their contact lenses in cleaning devices that is shaken by their hands, the contact lenses may be damaged if they exert too great a force to shake the cleaning devices. When people clean their contact lenses by using cleaning devices that is vibrated by motors or shaken by ultrasonic agitation, they are to put their contact lenses or contact lens cases into the cleaning devices to proceed with cleaning process. However, the specifications of contact lens cases that are manufactured by different companies are different. When people are in different countries or regions, they may use contact lens cases that are manufactured by different companies and thus are of different specifications. Thereby, people have to buy different cleaning devices according to the contact lens cases they use and it will be uneconomic for them to buy a variety of cleaning devices. Besides, these cleaning devices are not convenient to carry because of their relatively large size.
In order to solve the problems mentioned above to provide a cleaning device for contact lenses that is suitable for different specifications of contact lens cases and for economic purpose, is convenient to carry, and has effective cleaning function, inventor had the motive to study and develop the present invention after hard research.
The main object of the present invention is to provide a vibration-type cleaning device for contact lenses having a base, on which is provided with an adaptor that can be attached to or detached from the base. Thereby, adaptors of different specifications can be provided for connection with contact lens cases of different specifications and the cost for buying different cleaning devices can be saved.
Another object of the present invention is to provide a vibration-type cleaning device for contact lenses having a soundproof base, so that the noise can be reduced and the movement of the cleaning device can be restricted while limited freedom of movement is still allowed to enhance vibration transmission when the contact lenses are vibrated in the contact lens cases.
Another object of the present invention is to provide a vibration-type cleaning device for contact lenses having a control button and a display for inputting and showing the vibration time and the time when users have to dispose their contact lenses, so that users can be reminded timely in order to clean their contact lenses effectively and extend the lifetime of the contact lenses.
Another object of the present invention is to provide a vibration-type cleaning device for contact lenses having a positioning element that is magnetic and used for connecting the base and the adaptor, so that the base, the adaptor, and the contact lens case can be assembled easily and the size of the cleaning device can be reduced to carry conveniently.
In order to achieve the above objects, the present invention provides a vibration-type cleaning device for contact lenses comprising an adaptor and a base. The adaptor is disposed with a support part thereon for supporting a contact lens case. The base is connected with the adapter via a positioning element and is disposed with a vibrator therein. The vibrator is connected with a power source for driving the vibrator to vibrate the contact lens solution and the contact lenses in the contact lens case and the cleaning effect of the contact lenses in the contact lens solution is enhanced through vibration.
In practice, the base includes a bottom plate and a cover, wherein the cover covers the bottom plate and the bottom plate is provided with a groove for placing the vibrator.
In practice, the base is made of elastic plastics.
In practice, the present invention further includes a display, a microprocessor, and at least a control button and the display, the microprocessor, and the control button are in electric connection with the power source and the vibrator.
In practice, the positioning element includes a first magnetic piece and a second magnetic piece that are attractable with each other. The first magnetic piece is located in the base while the second magnet piece is located on the support part.
The following detailed description, given by way of examples and not intended to limit the invention solely to the embodiments described herein, will best be understood in conjunction with the accompanying drawings.
Please refer to
The adaptor 2 is appropriately in flat shape. The left and right sides of the top of the adaptor 2 are provided respectively with a conical recess 21 and the two recesses form a support part 22.
