Description

Contact lens restoring instrument
The application date of the invention is as follows: the invention is divided into divisional applications of Chinese patent application with patent application number of 201510481824.X and name of contact lens reduction instrument on 8/7/2015.
Technical Field
The invention relates to a contact lens cleaning device, in particular to a contact lens restoring instrument.
Background
People with considerable myopia choose to use contact lenses for aesthetic or mobility reasons. However, contact lenses suffer from protein deposition after extended use, which causes the lenses to lose oxygen permeability and may cause corneal damage after wear, and therefore, after a certain period of wear, the contact lenses must be cleaned for reuse.
The most commonly used cleaning mode of the contact lenses at present is that the lenses of the contact lenses are respectively put into two containers of a contact lens cleaning box, cleaning liquid medicine is respectively injected, and then the contact lenses are rubbed by fingers to remove dirt such as dust, protein deposition, mucus, oil stain and the like on the contact lenses and maintain the oxygen permeability of the lenses. However, the above-mentioned cleaning method is prone to fail to achieve good effects due to unclean fingers, and it takes a lot of time to clean the fingers.
There are also some contact lens cleaning devices on the market today, which use ultrasonic, heating type electromagnetic stirrers, uv or ozone, etc., however: 1) the ultrasonic frequency for cleaning the contact lenses needs to be more than 100KHz, the lenses are easy to be physically damaged, the requirement on the matching between a circuit and the frequency is high, and the production cost is also high; 2) the heating type electromagnetic stirrer heats and stirs by utilizing an electromagnetic principle, and the adhesive of the lens is separated by adding a cleaning agent, so that the heating temperature is high, and the possibility of touching and scalding the lens by mistake and damaging the lens is caused; 3) ultraviolet rays have strong killing power on bacteria, and ozone is a good oxidant and disinfectant, but cannot completely remove adhesive substances attached to lenses.
Chinese patent publication No. CN102053390A discloses a contact lens cleaning device, which includes a housing, a circuit board disposed in the housing, two conductive members electrically connected to the circuit board, and an electric power starting member electrically connected to the circuit board for starting the conductive members, wherein the conductive members are in contact with a cleaning agent in a cleaning unit under the housing to form a power-on loop to take away stickers on the contact lenses, thereby completing the cleaning operation. However, such cleaning devices have various problems during use: 1) because the power supply, the circuit board and other electronic elements are arranged in the shell, although the cleaning agent (or called contact lens care solution) can be prevented from entering the shell, the structure with heavy weight and light feet ensures that the situation of side turning is easy to occur in the process of opening the shell and placing the cleaning device, and the liquid is splashed out; 2) the conductive piece penetrates through the shell from top to bottom and penetrates into the cleaning agent, and the structure determines that the using amount of the cleaning agent at least reaches the standard of contacting with the conductive piece, so that on one hand, a user cannot measure the adding amount of the cleaning agent, and on the other hand, the waste of the cleaning agent is inevitably caused; 3) the cleaning device does not fundamentally solve the waterproof problem, and is difficult to store the contact lenses for carrying, so that a user must additionally purchase a contact lens box in actual use; 4) the cleaning device does not solve the problem of sealing between the conductive piece and the shell, and even if the electronic element is placed above the cleaning unit, the phenomenon that liquid enters the shell to damage the electronic element cannot be avoided.
In view of the above-mentioned drawbacks, the present designer has made active research and innovation to create a new structure of contact lens reduction instrument, which has more industrial utility value.
