A contact lens, or contact lens, is a lens that is worn on the cornea of an eye. Contact lenses in the narrow sense are used to correct vision or protect the eyes. The contact lenses comprise hard and soft lenses, which not only bring great improvement to ametropia patients with myopia, hyperopia, astigmatism and the like from the aspects of appearance and convenience, but also have wide visual field and vivid visual objects, and also play special efficacies in the aspects of controlling the development of myopia and astigmatism of teenagers, treating special ophthalmopathy and the like.
The material of the contact lens is generally a transparent material such as silicone hydrogel or a hydrated polymer (e.g., methyl methacrylate, hydroxyethyl methacrylate, or glyceryl methacrylate). The center thickness, oxygen permeability coefficient, diameter, optical power of the optic zone, lens tint, base curve, water content, etc. all have the general and special requirements of the industry.
Generally, permeability of contact lenses is a common problem causing ocular hypoxia leading to redness and disease. In addition, the lens is vulnerable to damage, including dehydration, poor oxygen permeability, damage caused by heat (e.g., fire), deposit formation, contamination and even mildew, aging of the lens material, damage and breakage of the lens, etc. These conditions affect the use of contact lenses and even cause damage to the eye, including decreased resistance of the eye, asthenopia, dry eye, induction of ocular allergy, corneal abrasion, neuroparalysis, accelerated corneal aging, increased myopic degree, and aesthetic impact on the appearance of the individual.
At present, due to the wide application of the contact lenses, when a person wearing the contact lenses wants to take down the contact lenses for cleaning, the person wearing the contact lenses only puts the contact lenses in a liquid box of the contact lenses for cleaning, and the cleaning mode cannot completely clean the surfaces of the contact lenses, so that the eyes of the person wearing the contact lenses are easily damaged to a certain extent, and meanwhile, the use definition of the person wearing the contact lenses can also be reduced. If the contact lens needs to be cleaned, the wearer needs to take the contact lens to a specific place for targeted cleaning, which causes inconvenience and increases the cost of the wearer.
In view of the above-mentioned drawbacks, the present inventors have made active research and innovation to create a circuit for cleaning contact lenses and a contact lens case including the same, which have industrial applicability. In the chinese patent publication No. CN204967610U, the present designer proposed a circuit and a contact lens case for cleaning contact lenses. The contact lens cleaning circuit can realize stable voltage output of the electric needle, and when stable output voltage can be ensured, the contact lens cleaning circuit can not cause damage to the contact lens due to overlarge voltage when the contact lens is cleaned, and can also ensure that the contact lens is cleaned.
However, the circuit for cleaning contact lenses and the contact lens case have the following disadvantages: when no cleaning liquid or insufficient cleaning liquid exists in the cleaning bin, the controller cannot generate any feedback signal, and the power supply is normally started and performs cleaning operation. In severe cases, the cleaning circuit will be damaged.

Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention.
The contact lens cleaning box comprises a box body and a cleaning bin arranged in the box body, wherein the inner wall of the cleaning bin is provided with at least one pair of positive electric needles and negative electric needles. When the contact lenses need to be cleaned, cleaning liquid is poured into the cleaning bin, the contact lenses to be cleaned are immersed in the cleaning liquid, and then the power supply is switched on. The positive electric needle and the negative electric needle generate a potential difference, and the charged protein particles adhered on the contact lens are separated from the contact lens due to the action of the potential difference, move towards one electric needle and are adsorbed on the surface of the electric needle, so that the contact lens is cleaned.
It is easy to understand that when the cleaning liquid in the cleaning bin is insufficient, the conductivity between the positive electric needle and the negative electric needle is reduced (which is equivalent to the resistance value between the positive electric needle and the negative electric needle is increased). In an extreme case, when no cleaning liquid exists in the cleaning bin, the positive electricity needle and the negative electricity needle are equivalent to an open circuit.
Based on the principle, the invention provides a novel contact lens cleaning circuit, wherein a resistor is connected in series between a negative electric needle and a grounding end, and a voltage value between the positive electric needle and the negative electric needle in a cleaning bin (the voltage value between the positive electric needle and the negative electric needle is approximately equal to a power supply voltage value-the voltage value on the resistor) can be correspondingly obtained by collecting the voltage value on the resistor, so that whether the cleaning liquid in the cleaning bin is sufficient or not is judged.
Referring to fig. 1, a contact lens cleaning circuit includes a power circuit 1, a controller 2, a cleaning chamber circuit 3 and a cleaning chamber circuit pin set 4. The cleaning bin electric needle group 4 comprises at least one positive electric needle and one negative electric needle, and the negative electric needle is connected to a grounding end through a resistor.
The cleaning bin circuit 3 is connected between the power supply circuit 1 and the positive needles of the cleaning bin needle group 4, and is used for connecting the power supply circuit 1 and the cleaning bin needle group 4 and supplying the current output by the power supply circuit 1 to the cleaning bin needle group 4.
The controller 2 comprises a voltage acquisition end and a cleaning bin circuit control end, the voltage acquisition end is connected to the resistor and a connection node of the negative electricity needle, the cleaning bin circuit control end is connected to the cleaning bin circuit 3, the controller 2 controls the cleaning bin circuit 3 based on a voltage value signal on the voltage acquisition end to realize the on/off of the power supply circuit 1 and the cleaning bin needle group 4.
The voltage signal supplied to the cleaning bin by the cleaning bin circuit 3 is divided into the cleaning bin electric needle group 4 and the resistor. Therefore, when the cleaning liquid in the cleaning bin is reduced (the conductivity between the positive and negative electricity needles of the electricity needle group of the cleaning bin is reduced), the voltage value divided on the electricity needle group 4 of the cleaning bin is increased, and the voltage value divided by the resistance is correspondingly reduced. The voltage acquisition end can acquire the voltage value information on the resistor, so that the controller 2 can judge whether the cleaning liquid in the cleaning bin is sufficient or not by comparing the voltage value on the voltage acquisition end with a preset threshold value, and correspondingly controls the cleaning bin circuit 3 on the basis.
Specifically, the method comprises the following steps: when the voltage value on the voltage acquisition end is smaller than a preset threshold value (which indicates that the cleaning liquid in the cleaning bin is insufficient), the controller 2 outputs a closing control signal through the control end of the cleaning bin circuit, and the cleaning bin circuit 3 stops working after receiving the closing control signal, so that the power supply circuit 1 cannot supply power to the cleaning bin electric needle group 4. When the voltage value of the resistor acquired by the voltage acquisition end is greater than a preset threshold value (which indicates that the cleaning liquid in the cleaning bin is sufficient), the controller 2 controls the cleaning bin circuit 3 to normally work, and the power supply circuit 1 can realize normal power supply for the cleaning bin electric needle group 4.
Example one

A first resistor R9 is connected in series between the first negative pin T2 and the ground terminal, and a second resistor R12 is connected in series between the second negative pin T4 and the ground terminal.
Two pins of the controller 2 are used as voltage acquisition terminals, namely a first voltage acquisition terminal AIN1 and a second voltage acquisition terminal AIN0, wherein: the first voltage collecting terminal AIN1 is connected to a connection node of the first negative electric needle T2 and the first resistor R9, and the first voltage collecting terminal AIN1 is used for collecting a voltage value of the first resistor R9. The second voltage collecting terminal AIN0 is connected to a connection node of the second negative electric needle T4 and the second resistor R12, and the second voltage collecting terminal AIN0 is used for collecting a voltage value of the second resistor R12. It can be seen that the output voltage signal VCC _5 of the cleaning chamber circuit 3 is divided into two paths to flow through the first positive electric needle T1, the first negative electric needle T2, the first resistor R9, and the second positive electric needle T3, the second negative electric needle T4, the second resistor R12.

And when the voltage value of the first resistor R9 collected by the first voltage collection end AIN1 and the voltage value of the second resistor R12 collected by the second voltage collection end AIN0 are greater than or equal to 2V (indicating that the cleaning liquid in the cleaning bin is sufficient), at this time, the controller 2 outputs a high level to the enabling control end EN of the voltage multiplication chip TC3200, the voltage multiplication chip TC3200 can normally work, and at this time, the power supply circuit 1 can realize the normal power supply of the cleaning bin electric needle group 4.
In some embodiments, the controller 2 is further connected to a key circuit 5, and preferably, the key circuit 5 may be a touch key circuit including a touch button, and when a user touches the touch button, the key circuit 5 sends an activation signal to the controller 2. Fig. 8 shows a circuit structure diagram of a touch key circuit in an embodiment, which uses a touch chip U6 with a model number of TTP223E as a core chip, as shown in fig. 3 and 8, one pin (pin 20) of the controller 2 is used as a control terminal TP _ SW of the touch key circuit, and the control terminal TP _ SW is connected to a pin Q of the touch chip U6, so as to realize the control of the touch key circuit by the controller 2.
Preferably, after the controller 2 receives the start signal sent by the key circuit 5, the voltage value at the voltage collecting end is compared with a predetermined threshold value, and the following control is performed: when the voltage value on the voltage acquisition end is greater than or equal to the preset threshold value, the controller 2 outputs an enabling control signal to the cleaning bin circuit 3 through the cleaning bin circuit control end, and the cleaning bin circuit 3 starts to work, so that the power supply circuit 1 is communicated with the cleaning bin electric needle group 4.
In some embodiments, the controller 2 is further connected with an indicator light circuit 7, and the indicator light circuit 7 includes a plurality of indicator lights for displaying the working state of the cleaning chamber. Fig. 9 shows a circuit diagram of an indicator light circuit in an embodiment, the indicator light circuit includes three LED indicator lights, which are a blue LED indicator light, a red LED indicator light, and a green LED indicator light. As shown in fig. 3 and 9, three pins (15 th, 16 th and 17 th pins) of the controller 2 are used as LED indicator lamp control terminals, namely a control terminal LED _ B _ CTRL, a control terminal LED _ G _ CTRL and a control terminal LED _ R _ CTRL, respectively, wherein: the control terminals LED _ B _ CTRL, LED _ G _ CTRL and LED _ R _ CTRL are respectively connected with one LED indicator lamp, so that independent or combined control over the LED indicator lamps is realized, and different indication functions are realized.
Preferably, when the controller 2 outputs a turn-off control signal to the cleaning bin circuit 3 through the control end of the cleaning bin circuit, the controller 2 simultaneously outputs an indicator light turn-off control signal to stop the indicator light circuit, and the indicator lights are all turned off.
In some embodiments, an LED breathing lamp circuit 6 is further connected to the controller 2, and one or more LED lamps are included in the LED breathing lamp circuit 6. In the cleaning process, under the control of the controller 2, the luminous intensity of the LED lamp in the LED breathing lamp circuit 6 shows a gradual change effect from light to dark. Fig. 10 shows a circuit structure diagram of an LED breathing lamp circuit 6 in an embodiment, the LED breathing lamp circuit 6 includes a field effect transistor Q7 with model number CJ2302 and twelve LED lamp branches, each of which includes a current limiting resistor and a blue LED lamp connected in series. Wherein: one end of each of twelve LED lamp branches is connected to a power supply end, the other end of each of twelve LED lamp branches is connected to a drain of a field effect transistor Q7, and a source electrode of the field effect transistor Q7 is grounded. One pin (pin 13) of the controller 2 is used as an LED breathing lamp control terminal LED _ N _ CTRL, which is connected to the gate of the fet Q7. The controller 2 outputs a variable duty ratio signal through the control end LED _ N _ CTRL, so that the field effect tube Q7 is controlled to be switched on and off according to a rule, and finally the brightness change of each blue light LED lamp is realized. Therefore, the field effect transistor Q7 is equivalent to a control switch connected in series between the LED lamp branch and the ground terminal, and regular on-off is realized based on a variable duty ratio signal, thereby realizing the brightness change of each blue LED lamp.
