Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0048] In the description of the present application, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "a plurality" means two or more, and "at least one" may mean one, two or more, unless otherwise specifically defined.

[0049] With the steady improvement of China's economy, more and more teenagers and adults wear contact lenses. Since human tears are extremely easy to secrete and tear proteins are extremely easy to penetrate into the fiber oxygen-permeable pores, resulting in a decrease in the gas permeability of the lens, corneal damage, bacterial infection, corneal inflammation, and even vision impairment. Removing proteins and bacteria is the key to using this lens.

[0050] Proteins usually have cationic and anionic groups, called zwitterions. They are often dispersed in solution as particles, and their net charge depends on the H+ concentration of the medium or the interaction with other macromolecules. In an electric field, charged particles migrate towards the cathode or anode, and the direction of migration depends on the sign of their charge. This migration phenomenon is called electrophoresis. Under the action of the electric field force, the charged protein migrates away from the lens towards the electrode. The physiological saline (NaCl) in the nursing chamber produces hypochlorous acid under electrolysis, and bacteria are quickly inactivated under the dual action of hypochlorous acid and microcurrent, enabling the lens to be quickly sterilized.

[0051] When nursing contact lenses, each lens needs to be placed in a cleaning tank, and positive and negative electrode posts need to be set in each cleaning tank at the same time, so that the internal structure used in the nursing device is more, and the setting is more complex; at the same time, it will also increase the cost during production and processing.

[0052] In view of this, the embodiment of the present application provides a nursing device to overcome at least one of the above technical problems.

[0053] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , in the embodiment of the present application, the nursing device is a device for removing proteins from contact lenses. The nursing device includes: a first housing 10, a second housing 20, a first electrode post 30, and a plurality of second electrode posts 40. The first housing 10 has a receiving groove 11, and the inside of the receiving groove 11 can be used to install some structures, providing a good working environment for these structures. At least a part of the second housing 20 is embedded in the receiving groove 11 and is connected to the first housing 10. There is a gap 15 between the first housing 10 and the second housing 20. This gap 15 is actually a part of the receiving groove 11. Since at least a part of the second housing 20 is embedded in the receiving groove 11, only a part of the space between the first housing 10 and the second housing 20, that is, the gap 15, remains in the receiving groove 11. The gap 15 can be used to place some other structures in the nursing device.

[0054] The second housing 20 has a plurality of cleaning grooves 21, and the number of cleaning grooves 21 can be two or more, so that the device can care for multiple contact lenses at the same time, improving the working efficiency of care. The cleaning groove 21 has an opening 24 and a bottom wall 25 disposed opposite to the opening 24. When the care device is in use, the user places the contact lens into the corresponding cleaning groove 21 through the opening 24. The bottom wall 25, as the part at the bottom of the cleaning groove 21, forms a relative setting form with the opening 24. The bottom wall 25 at least cooperates with a part of the first housing 10 to enclose a gap 15, and the opening 24 faces away from the gap 15. Since the number of cleaning grooves 21 is plural, the number of bottom walls 25 is also plural. The plurality of bottom walls 25 and at least a part of the first housing 10 cooperate to enclose a gap 15. The second housing 20 has a first through hole 22, and the first through hole 22 can penetrate through the bottom wall 25 of each cleaning groove 21 at the same time. The gap 15 is communicated with each cleaning groove 21 through the first through hole 22. The first through hole 22 can penetrate through all the bottom walls 25 at the same time, so that the first through hole 22 is communicated with the gap 15 and also communicated with all the cleaning grooves 21.

[0055] The first pole column 30 passes through the first through hole 22 and is hermetically connected to the second housing 20. At least part of the first pole column 30 is located in each cleaning tank 21. A plurality of second pole columns 40 are arranged in each cleaning tank 21 and are arranged at intervals from the first pole column 30. The first pole column 30 and the corresponding second pole column 40 cooperate to form an electric field. Among them, sealing can be achieved by arranging a seal between the first pole column 30 and the second housing 20 to ensure that the solution in the cleaning tank 21 does not leak. The seal can be made of materials such as rubber or silica gel, and its shape can be set as required. Or during product processing, the sealing connection between the first pole column 30 and the second housing 20 can be realized through the bonding process with glue. Since at least a part of the first pole column 30 is located in each cleaning tank 21, that is to say, a part of the first pole column 30 is present in all the cleaning tanks 21, it is not necessary to arrange a first pole column 30 inside each cleaning tank 21. Only one first pole column 30 needs to be arranged in this way, and then a second pole column 40 is arranged inside each cleaning tank 21. When the care device is working, first put the corresponding cleaning solution into the inside of the cleaning tank 21, and then place the lens in the corresponding cleaning tank 21. The first pole column 30 and the second pole column 40 are in contact with different electrodes of the power supply structure, so that the first pole column 30 is positively charged and the second pole column 40 is negatively charged, or the first pole column 30 is negatively charged and the second pole column 40 is positively charged. The first pole column 30 present in each cleaning tank 21 will generate an electric field with the second pole column 40 in the corresponding cleaning tank 21. Through the action of the electric field, the protein with charges on the contact lens in each cleaning tank 21 moves towards the corresponding pole column and separates from the contact lens, realizing the functions of care and cleaning. This setting only requires one first pole column 30 to realize the care of the contact lens, and it is not necessary to arrange a first pole column 30 inside each cleaning tank 21. The reduction in the number of first pole columns 30 also reduces the number of structures connected to the first pole column 30, simplifies the internal structure of the care device, is relatively simple to set up, can also reduce the volume of the care device, and makes the design more compact. At the same time, with the reduction of the structure, materials are saved, and the processing cost of the device can be reduced. The simplification of the structure also facilitates the assembly and maintenance of the device.

[0056] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6, in some embodiments, the second housing 20 has a plurality of second through holes 23, which are respectively formed through the bottom wall 25 of the corresponding cleaning tank 21. The gap 15 communicates with one cleaning tank 21 through one second through hole 23. Each second pole 40 passes through one second through hole 23 and is hermetically connected to the second housing 20. Similar to the first pole 30, a seal can also be provided between the second pole 40 and the second housing 20. The seal can be made of materials such as rubber or silica gel, and its shape can be set as needed. Or during product processing, the adhesive process can be used to achieve the sealed connection between the first pole 30 and the second housing 20 as well as between the second pole 40 and the second housing 20. The first housing 10 has a first connection hole 12 and a second connection hole 13 that communicate with the gap 15. The nursing device further includes a first connector 50 and a second connector 60. The first connection hole 12 and the second connection hole 13 on the first housing 10 are for the convenience of the passage of the first connector 50 and the second connector 60, so that the first connector 50 and the second connector 60 can connect the corresponding poles. The other ends of the first connector 50 and the second connector 60 can be connected to the corresponding power supply structure. That is, the corresponding power supply structure supplies power to the corresponding pole through the first connector 50 or the second connector 60.

[0057] The first connector 50 passes through the first connection hole 12 into the gap 15 and is connected to the first housing 10. The first connector 50 is electrically connected to the first pole 30. The first connector 50 passes through the first connection hole 12 and enters the gap 15, and is connected to the first housing 10 to ensure the stability of the first connector 50 during operation. The part of it in the gap 15 establishes an electrical connection with the first pole 30, and supplies the required electrical energy to the first pole 30 in an electrical connection manner to enable it to work properly.

[0058] The second connector 60 passes through the second connection hole 13 into the gap 15 and is connected to the first housing 10. The second connector 60 is electrically connected to each second pole 40. The second connector 60 passes through the second connection hole 13 and enters the gap 15, and is connected to the first housing 10, and at the same time establishes an electrical connection with each second pole 40. The function of the second connector 60 is to supply the required electrical energy to each second pole 40 through electrical connection, so that the second pole 40 can cooperate with the first pole 30 to generate an electric field to care for the contact lenses in the cleaning tank 21.

[0059] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , in some embodiments, the first connector 50 includes a first conductive part 51 and a first overlapping part 52.

[0060] The first conductive part 51 penetrates through the first connection hole 12 into the gap 15 and can be connected to the first housing 10. The first conductive part 51 is a part of the first connector 50 and is usually made of a conductive material such as metal or other conductive materials. The function of the first conductive part 51 is to establish an electrical connection between the power supply structure and the first overlapping part 52 so that electrical energy can be transmitted to the corresponding pole of the care device.

[0061] The first overlapping part 52 is located in the gap 15, and the first conductive part 51 connects to the first pole 30 through the first overlapping part 52. The first overlapping part 52 is located in the gap 15 and is used to establish an electrical connection with other structures inside the first connector 50. The first conductive part 51 is connected to the first pole 30 through the first overlapping part 52. The first overlapping part 52 is usually made of a conductive material to ensure good electrical conductivity. Through the connection and cooperation of the first overlapping part 52 and the first conductive part 51, the electrical energy on the power supply structure can be transmitted to the first pole 30, thus enabling the normal operation of the care device.

[0062] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , in some embodiments, the first overlapping part 52 is composed of three components: the first main body 521, the first contact end 522, and the second contact end 523.

Among them, the first main body 521 is the main component of the first overlapping portion 52. It is usually made of a conductive material, such as metal. The first main body 521 is located within the gap 15 and can be regarded as the central hub of the first overlapping portion 52. The first contact end 522 is connected to the first main body 521 and is located on the side of the first main body 521 away from the second contact end 523. One side of the first contact end 522 is connected to the first main body 521, and the other side of the first contact end 522 establishes an electrical connection with the first conductive portion 51. The first contact end 522 usually has a well-designed contact surface to ensure that it can reliably establish good electrical contact with the first conductive portion 51. Through the connection with the first conductive portion 51, electrical energy can be transmitted from the first conductive portion 51 through the first contact end 522 to the first main body 521. The second contact end 523 is connected to the first main body 521 and is located on the other side of the first main body 521 away from the first contact end 522. It establishes an electrical connection with the first pole 30 through the connection with the first main body 521. The second contact end 523 usually has an appropriate contact surface to ensure stable electrical contact with the first pole 30, so that the electrical energy on the first conductive portion 51 is transmitted to the first pole 30 through the first contact end 522, the first main body 521 and the second contact end 523 to achieve effective transmission of electrical energy.

[0064] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , in some embodiments, the second connector 60 includes a second conductive portion 61 and a second overlapping portion 62.

[0065] The second conductive portion 61 passes through the second connection hole 13 and extends into the gap 15 and is connected to the first housing 10. Similar to the first conductive portion 51 in the first connector 50, the second conductive portion 61 is usually made of a conductive material, such as metal.

The second overlapping portion 62 is located within the gap 15 and is used to establish an electrical connection with other power supply structures inside the second connector 60. The second conductive portion 61 is connected to the second pole 40 through the second overlapping portion 62. The second overlapping portion 62 is generally made of a conductive material to ensure good electrical conductivity. Through the connection and cooperation of the second overlapping portion 62 and the second conductive portion 61, the electrical energy on the power supply structure can be transmitted to multiple second poles 40, thereby enabling the normal operation of the care device.

[0067] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 ,In some embodiments, the second overlapping portion 62 includes a second main body 621, a third contact end 622 connected to the second main body 621, and a plurality of fourth contact ends 623. They jointly form the second overlapping portion 62 to achieve a specific electrical connection function.

The second main body 621 is made of a conductive material, such as metal. It can be regarded as the central hub of the second overlapping portion 62. The third contact end 622 is connected to one side of the second main body 621. The third contact end 622 generally has a well-designed contact surface to ensure a reliable electrical contact with the second conductive portion 61. Through the connection with the second conductive portion 61, electrical energy can be transmitted from the second conductive portion 61 through the third contact end 622 to the second main body 621. The plurality of fourth contact ends 623 are connected to the other side of the second main body 621. The second main body 621 establishes electrical connections with each second pole 40 through the plurality of fourth contact ends 623. Each fourth contact end 623 also generally has an appropriate contact surface to ensure a stable electrical contact with each second pole 40. So that the electrical energy on the second conductive portion 61 is transmitted to the plurality of second poles 40 through the third contact end 622, the second main body 621, and the plurality of fourth contact ends 623 to achieve an effective transmission of electrical energy.

[0068] Please refer to Figure 5 and Figure 6, in some embodiments, both the first connecting member 50 and the second connecting member 60 are elastic connecting members. They have a certain elasticity and flexibility when connecting and conducting electrical energy. The arrangement of the elastic connecting members enables them to adapt to different shapes and sizes and can withstand deformation and stress within a certain range. The elastic connecting members are made of elastic materials such as spring steel. These materials have the ability to restore their shape, can undergo elastic deformation under the action of external forces, and return to their original state after the external forces are removed. This elastic characteristic enables the connecting members to adapt to the shape and size differences of the connected components and provide a tight electrical connection. Secondly, the elastic connecting members can absorb and reduce the impact or vibration from the external environment and stress to a certain extent. The presence of the elastic material can play a buffering and shock-absorbing role, preventing the destruction of the connection caused by external vibrations and protecting the stability and reliability of the connection. The elastic connecting members also have a certain degree of adjustability and can be finely adjusted and adjusted according to actual needs. The elastic material has a certain degree of plasticity, and the shape and structure of the connecting member can be changed to adapt to specific connection requirements. This adjustability enables the connecting members to be applicable to different electrical connection environments and requirements and provide a more flexible and reliable connection.

The corrosion-resistant layer 32 is wrapped around the body portion 31, and the adsorption layer 33 is wrapped around the corrosion-resistant layer 32. The body portion 31 is usually made of a conductive material such as metal. The design shape and size of the body portion 31 can be adjusted according to specific requirements to adapt to the use environment of the pole. The corrosion-resistant layer 32 is wrapped outside the body portion 31. The corrosion-resistant layer 32 is usually made of a material with good corrosion resistance, such as a chromium plating layer, a zinc plating layer, or a ceramic material. Its function is to protect the body portion 31 from the effects of corrosion and oxidation and extend the service life of the pole. The corrosion-resistant layer 32 forms a protective layer to isolate the direct contact between the external environment and the pole, thereby reducing the risk of corrosion and damage. The adsorption layer 33 is wrapped outside the corrosion-resistant layer 32. The adsorption layer 33 is usually made of an adsorbent material such as graphene. The function of the adsorption layer 33 is to adsorb pollutants and particles present in the device solution.

[0071] Please refer to Figure 1 and Figure 8 , in some embodiments, the care device further includes an upper cover 80, which is connected to the second housing 20 and seals a plurality of openings 24. The upper cover 80 is connected above the second housing 20. The upper cover 80 is generally made of a material with durability and waterproof performance, such as plastic or metal. Its main function is to protect the lens in the cleaning tank 21 and prevent external dust and other contaminants from entering the inside of the cleaning tank 21.

[0072] Please refer to Figure 1 , Figure 10 and Figure 11 , the cleaning system in the present application includes the care device described above (the care device is represented by H in the circuit structure schematic diagram), and further includes a circuit component 90. The circuit component 90 includes a power supply 91, a first switch 92, a second switch 93, a third switch 94, and a fourth switch 95.

[0073] The input terminal of the first switch 92 is electrically connected to the positive electrode of the power supply 91, and the output terminal of the first switch 92 is electrically connected to the nursing device (the output terminal of the first switch 92 is electrically connected to the first pole 30 or the second pole 40 of the nursing device). The input terminal of the second switch 93 is electrically connected to the positive electrode of the power supply 91, and the output terminal of the second switch 93 is electrically connected to the nursing device (the output terminal of the second switch 93 is electrically connected to the first pole 30 or the second pole 40 of the nursing device). The input terminal of the third switch 94 is electrically connected to the nursing device (the input terminal of the third switch 94 is electrically connected to the first pole 30 or the second pole 40 of the nursing device), and the output terminal of the third switch 94 is electrically connected to the negative electrode of the power supply 91. The input terminal of the fourth switch 95 is electrically connected to the nursing device (the input terminal of the fourth switch 95 is electrically connected to the first pole 30 or the second pole 40 of the nursing device), and the output terminal of the fourth switch 95 is electrically connected to the negative electrode of the power supply 91. It can be understood that when the circuit component 90 is connected to the cleaning device, the first switch 92 and the fourth switch 95 in the circuit component 90 can be closed, and the second switch 93 and the third switch 94 in the circuit component 90 can be opened. The current can flow out from the positive electrode of the power supply 91, pass through the closed first switch 92 and be transmitted to the first pole 30 or the second pole 40 of the cleaning device, and then pass through the closed fourth switch 95 from the second pole 40 or the first pole 30 and be transmitted to the negative electrode of the power supply 91 (here, if the current flows in from the first pole 30, it will flow out from the second pole 40; if the current flows in from the second pole 40 through the closed first switch 92, it will flow out from the first pole 30, and the same applies hereinafter). At the same time, the first switch 92 and the fourth switch 95 in the circuit component 90 can also be opened, and the second switch 93 and the third switch 94 in the circuit component 90 can be closed. The current can flow out from the positive electrode of the power supply 91, pass through the closed second switch 93 and be transmitted to the second pole 40 or the first pole 30 of the cleaning device, and then pass through the closed third switch 94 from the first pole 30 or the second pole 40 and be transmitted to the negative electrode of the power supply 91.

[0074] For example, when the nursing device cleans the lens through the first pole 30 and the second pole 40, the first switch 92 and the fourth switch 95 are closed, and the second switch 93 and the third switch 94 in the circuit component 90 are opened. The current is transmitted from the positive pole of the power supply 91 through the first switch 92 to the first pole 30, making the polarity of the first pole 30 the positive pole. Then the current passes from the second pole 40 through the fourth switch 95 to the negative pole of the power supply 91, and the polarity of the second pole 40 is the negative pole. At this time, an electric field is formed in the nursing solution, and the charged particles migrate towards the positive or negative pole, and the migration direction depends on the sign of their charge, so that the lens immersed in the solution can be cleaned. After cleaning for a period of time, the first switch 92 and the fourth switch 95 in the circuit component 90 can be opened, and the second switch 93 and the third switch 94 in the circuit component 90 can be closed. The current is transmitted from the positive pole of the power supply 91 through the second switch 93 to the second pole 40, making the polarity of the second pole 40 converted to the positive pole. Then the current passes from the first pole 30 through the third switch 94 to the negative pole of the power supply 91, making the polarity of the first pole 30 converted to the negative pole. Through this polarity conversion effect, it is convenient for the migration of charged particles at different positions of the lens, and the impurities on the lens can be removed more fully and effectively, improving the nursing effect.
