Description

Technical Field

[0001] This utility model relates to the field of lens cleaning technology, and in particular to a rigid gas permeable contact lens cleaner. Background Technology

[0002] Rigid contact lenses (such as orthokeratology lenses and RGP lenses) are important non-surgical vision correction medical devices widely used in myopia control in adolescents and in the control and treatment of corneal diseases such as keratoconus. They improve vision by physically pressing and reshaping the cornea, requiring extremely high hygiene standards during wear. During long-term use, contaminants such as proteins and lipids secreted by the eye can easily accumulate on the lens surface. If not cleaned thoroughly, this can lead to corneal infections, decreased lens oxygen permeability, and other problems, seriously affecting wearing safety and corrective efficacy. Therefore, regular, efficient, and safe cleaning of rigid contact lenses is crucial for maintaining their performance.

[0003] Currently, ultrasonic cleaners for rigid gas permeable contact lenses on the market generally have the following defects:

[0004] 1. Existing equipment relies on an external power source (such as charging via a power cord connected to a socket or USB port), requiring a power or charging interface to be provided on the equipment casing. However, in actual use, the cleaning process involves contact with liquids (such as care solutions or cleaning solutions). During user operation, splashing water or incomplete wiping of the cleaning tank may cause liquid to seep into the equipment through the power interface, resulting in short circuits, component damage, and seriously affecting the safety and lifespan of the equipment.

[0005] 2. The design of requiring an external power supply limits the portability of the device. Users of rigid gas permeable contact lenses (especially teenagers) often need to go out to study, travel, or use the device in situations where there is no fixed power source. Existing cleaning devices require an additional power cord or rely on a power outlet, which cannot meet the need for immediate and convenient cleaning and greatly reduces the user experience.

[0006] In summary, existing rigid gas permeable contact lens cleaners have significant shortcomings in terms of waterproofing and ease of use due to limitations in their power supply design, and further improvements are needed. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a rigid gas permeable contact lens cleaner that can be wirelessly charged.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A rigid gas permeable contact lens cleaner includes a housing and a base that are interlocked. The housing contains a cleaning tank, an ultrasonic transducer disposed at the bottom of the cleaning tank, a wireless charging receiver, a battery, a UVC circuit board, and a control mechanism. The base contains a wireless charging transmitter adapted to the wireless charging receiver. The wireless charging receiver is connected to a power adapter. The control mechanism is electrically connected to the ultrasonic transducer, the battery, the UVC circuit board, and the wireless charging receiver. The UVC circuit board is equipped with a UVC lamp, and the side wall of the cleaning tank has a light-transmitting hole for the UVC lamp light to enter.

[0010] As a further improvement to the above technical solution, the base is provided with a first permanent magnet, and the housing is provided with a second permanent magnet that has a magnetic attraction with the first permanent magnet.

[0011] As a further improvement to the above technical solution, a first cylinder is provided in the middle of the base, and multiple supporting ribs are arranged circumferentially around the outside of the first cylinder. The first permanent magnet is installed inside the first cylinder, and the multiple supporting ribs jointly support the primary coil of the wireless charging transmitter.

[0012] As a further improvement to the above technical solution, a second cylinder is provided in the middle of the inner bottom surface of the housing, the second permanent magnet is installed inside the second cylinder, and the secondary coil of the wireless charging receiver is sleeved on the second cylinder and fits against the inner bottom surface of the bottom shell.

[0013] As a further improvement to the above technical solution, the cleaning tank can be sealed by a tank cover, the cleaning tank is divided into a left mirror area and a right mirror area, two UVC lamps are provided and the two UVC lamps face the left mirror area and the right mirror area respectively, and a mirror holder is provided in the cleaning tank.

[0016] As a further improvement to the above technical solution, the top of the casing is provided with a flip cover.

[0017] As a further improvement to the above technical solution, a mirror is provided inside the flip cover.

[0018] The beneficial effects of this utility model are as follows: Compared with the prior art, the rigid gas permeable contact lens cleaner provided by this utility model has the following advantages:

[0019] 1. Through the contactless power transmission design of the wireless charging transmitter and wireless charging receiver, there is no need to open a power interface or charging interface on the shell. This further optimizes the overall sealing of the device and fundamentally avoids problems such as short circuits and corrosion of electronic components caused by cleaning fluid or water seeping into the inner cavity of the shell through the interface. This significantly improves the waterproof performance of the device, extends its service life, and reduces the risk of use.

[0020] 2. The built-in battery can store electrical energy, enabling the cleaner to work independently when detached from the base (without external power supply) (such as when traveling or in situations without a power outlet).

[0021] 3. The ultrasonic transducer efficiently removes physical contaminants (such as proteins and lipids) from the lens surface through cavitation, while the UVC lamp sterilizes by destroying the structure of microorganisms with ultraviolet light. The two work together to comprehensively improve the cleanliness and hygiene safety of the lenses. Attached Figure Description

Detailed Implementation

[0029] This utility model provides a rigid gas permeable contact lens cleaner. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0030] Please see Figures 1 to 6 This utility model provides a rigid gas permeable contact lens cleaner, including a housing 1 and a base 2 that are interlocked. The housing 1 contains a cleaning tank 6, an ultrasonic transducer 31 disposed at the bottom of the cleaning tank 6, a wireless charging receiver 4, a battery 32, a UVC circuit board 8, and a control mechanism. The base 2 contains a wireless charging transmitter 5 adapted to the wireless charging receiver 4. The wireless charging receiver 4 is connected to a power adapter. The control mechanism is electrically connected to the ultrasonic transducer 31, the battery 32, the UVC circuit board 8, and the wireless charging receiver. The UVC circuit board 8 is equipped with a UVC lamp, and the side wall of the cleaning tank 6 is provided with a light-transmitting hole 63 for the UVC lamp light to enter.

[0031] When the housing 1 is engaged with the base 2, the primary coil of the wireless charging transmitter 5 corresponds to the secondary coil of the wireless charging receiver 4. With power connected, the primary and secondary coils are inductively coupled to generate an induced current, wirelessly charging the battery 32 and storing electrical energy. When the housing 1 is detached from the base 2 (i.e., in the absence of an external power source), the battery 32 acts as an independent power source for all functional modules, ensuring the cleaner can be used offline.

[0032] After the control mechanism is activated, it sends a high-frequency electrical signal to the ultrasonic transducer 31. The ultrasonic transducer 31 converts the electrical signal into high-frequency mechanical vibration, which is transmitted to the cleaning fluid in the cleaning tank 6, causing the liquid molecules to vibrate violently and generate a large number of tiny cavitation bubbles. Through the cavitation effect, contaminants such as proteins and lipids deposited on the lens surface are removed, achieving efficient physical cleaning. The control mechanism synchronously or time-divisionally drives the UVC circuit board, causing the UVC lamp to emit short-wave ultraviolet light with a wavelength of 200-280nm. The ultraviolet light enters the cleaning tank 6 through the light-transmitting hole 63 on the side wall of the cleaning tank 6, penetrates the lens surface and the cleaning fluid, and destroys the DNA / RNA molecular structure of microorganisms (such as bacteria and viruses), causing them to lose their ability to replicate and survive, thereby achieving sterilization and disinfection.

[0033] The rigid gas permeable contact lens cleaner provided by this utility model has the following advantages:

[0034] 1. Through the non-contact power transmission design of the wireless charging transmitter 5 and the wireless charging receiver 4, the housing 1 does not need to have a power interface or charging interface, which further optimizes the overall sealing of the device and fundamentally avoids problems such as short circuits and corrosion of electronic components caused by cleaning fluid and water stains seeping into the inner cavity of the housing through the interface. This significantly improves the waterproof performance of the device, extends its service life and reduces the risk of use.

[0035] 2. The battery 32 installed inside the housing 1 can store electrical energy, enabling the cleaner to work independently when detached from the base 2 (without external power supply) (such as when traveling or in scenarios without a power outlet). Users do not need to carry an extra power cord or rely on a fixed power outlet, meeting immediate cleaning needs and greatly improving the portability and flexibility of the device.

[0036] 3. The ultrasonic transducer 31 efficiently removes physical contaminants (such as proteins and lipids) from the lens surface through cavitation effect, while the UVC lamp sterilizes by destroying the structure of microorganisms with ultraviolet light. The two work together to comprehensively improve the cleanliness and hygiene safety of the lens.

[0037] Wireless charging relies on the precise alignment of the wireless charging transmitter 5 and the wireless charging receiver 4. If their positions are misaligned, the electromagnetic induction efficiency will decrease or even charging will fail. Therefore, the base 2 is equipped with a first permanent magnet, and the housing 1 is equipped with a second permanent magnet that magnetically attracts the first permanent magnet. Through the magnetic attraction of the first and second permanent magnets, the housing 1 and base 2 are automatically guided to the optimal alignment position (i.e., the central axes of the wireless charging transmitter 5 and the wireless charging receiver 4 coincide) when they are engaged, avoiding charging interruptions or reduced efficiency due to manual placement errors, and ensuring the reliability and efficiency of the wireless charging process.

[0038] Specifically, a first cylinder 21 is provided in the middle of the base 2. Multiple supporting ribs 22 are arranged circumferentially on the outside of the first cylinder 21. The first permanent magnet is installed in a cylindrical shape inside the first cylinder 21 and properly fixed. The multiple supporting ribs 22 form a uniform support surface for the primary coil, which avoids deformation or displacement of the primary coil due to uneven force, ensures that the primary coil maintains the preset shape and position, further guarantees the coupling effect with the secondary coil, and optimizes the charging performance.

[0039] Furthermore, a second cylinder 14 is provided at the center of the inner bottom surface of the housing 1. The second permanent magnet is installed inside the second cylinder 14, and the secondary coil of the wireless charging receiver 4 is sleeved on the second cylinder 14 and fits against the inner bottom surface of the base 11. The second cylinder 14 serves as a dedicated mounting cavity for the second permanent magnet, and the second permanent magnet is fixed to the center position of the housing 1 by means of interference fit, adhesive, etc., ensuring that it is strictly aligned with the magnetic attraction center of the first permanent magnet in the base 2. When the magnetic attraction guides the housing 1 and the base 2 to snap together, it automatically corrects the positional deviation, ensuring that the secondary coil always maintains the optimal coupling distance with the primary coil, and avoiding a decrease in electromagnetic coupling efficiency due to coil misalignment.

[0040] Preferred, see Figure 1 As shown, the cleaning tank 6 can be sealed by the tank cover 64. This design prevents the cleaning fluid from splashing out due to ultrasonic vibration during the cleaning process, keeping the exterior of the equipment clean. Furthermore, the sealed tank reduces UVC ultraviolet leakage, preventing accidental exposure to UV light during operation and improving safety. Simultaneously, the fit between the tank cover 64 and the cleaning tank 6 (e.g., snap-fit, sealing ring) enhances internal airtightness, creating a reflective and diffused UVC environment within the tank, increasing the UV coverage area on the lens and strengthening the sterilization effect.

[0041] Furthermore, the cleaning tank 6 is divided into a left lens area 61 and a right lens area 62, allowing the lenses for the left and right eyes to be cleaned in separate areas. This effectively avoids cross-contamination caused by mixing lenses, meeting the hygiene requirements for independent use of rigid gas permeable contact lenses. Simultaneously, the partitioned design aligns with users' daily habits of distinguishing between left and right eyes (e.g., left lens area 61 is labeled "L" and right lens area 62 is labeled "R"), reducing the risk of users mistakenly placing the right lens in the left lens area 61, thus improving ease of use.

[0042] Correspondingly, there are two UVC lamps, and the two UVC lamps are respectively facing the left mirror area 61 and the right mirror area 62, so that the lens of each mirror area can directly receive the directional irradiation of the corresponding UVC lamp, avoiding the irradiation blind zone caused by the partition or the position of the lens when a single lamp is irradiated, thus making sterilization more effective.

[0043] See Figure 2 As shown, a lens holder 7 can be installed inside the cleaning tank 6. The lens holder 7 provides stable support for the lens, preventing it from shifting, colliding with each other, or rubbing against the wall of the cleaning tank 6 due to violent vibrations during ultrasonic cleaning (rigid contact lenses are relatively brittle, and friction can easily cause scratches or breakage). The fixing function of the lens holder 7 also keeps the lens in a preset position and angle, ensuring that the ultrasonic cavitation effect is evenly applied to the lens surface, further optimizing the cleaning effect.

[0044] See Figure 3 and Figure 4As shown, the housing 1 includes a bottom shell 11 and a cover 12 disposed on top of the bottom shell 11. The cleaning tank 6 is integrally formed with the cover 12 (e.g., through injection molding), eliminating the seams between the cleaning tank 6 and the cover 12 in traditional designs. This fundamentally avoids the risk of cleaning fluid seeping into the interior of the cover 12 through gaps. The integrally formed structure also enhances the overall rigidity of the cleaning tank 6. During ultrasonic cleaning, high-frequency vibration will not cause cracking or deformation at the connection between the cleaning tank 6 and the cover 12, ensuring the stability of the cleaning process and extending the service life of the equipment.

[0045] See Figure 4 As shown, the UVC circuit board 8 is mounted on the housing cover 12. Its highly integrated position with the cleaning tank 6 allows the UVC lamp to be placed as close as possible to the light-transmitting hole 63 of the cleaning tank 6, or even directly embedded within the light-transmitting hole 63, shortening the propagation distance of ultraviolet light from the lamp source to the lens and significantly improving sterilization efficiency.

[0046] Preferably, the cover 12 has a storage slot 13 for storing rigid gas permeable contact lenses. The storage slot 13 on the cover 12 provides a dedicated storage space for rigid gas permeable contact lenses after cleaning. After cleaning, the user can directly put the lens into the storage box and then into the storage slot 13.

[0047] Preferably, the control mechanism includes a control main board 33 fixed on the bottom shell 11 and a control button 34 disposed on the cover 12. The control button 34 controls the operation of the ultrasonic transducer 31. After the user places the lens into the cleaning tank 6, their hand is already close to the surface of the cover 12, and they can directly start the ultrasonic cleaning by pressing the button on the cover 12. This design significantly reduces the difficulty of operation, and the proximity of the button to the cleaning tank 6 makes the operation feedback more intuitive, improving the user's perception of the equipment status.

[0048] The insertion and removal of rigid gas permeable contact lenses require precise alignment with the cornea. Users often need to use a mirror 92 to observe the position of the eye and the lens to avoid operational errors (such as lens misalignment or finger touching the cornea). Therefore, the top of the housing 1 is equipped with a flip cover 91, within which a mirror 92 is housed. The mirror 92 within the flip cover 91 is directly integrated into the top of the cleaning device. After cleaning, the user can directly open the flip cover 91 and use the built-in mirror 92 for assistance with insertion and removal, eliminating the need to search for or carry a separate mirror 92. This design significantly improves the convenience and accuracy of insertion / removal operations, especially in scenarios such as outings or travel where a fixed mirror 92 is unavailable, reducing the risk of corneal abrasions due to operational errors.
