[0003] Cleaning rigid gas permeable (RGP) lenses is generally done manually. Some automated cleaning devices are also available. Existing cleaning devices generally do not have UV sterilization capabilities. The few that do emit UV light typically only emit a specific wavelength of violet or deep ultraviolet light. If visible violet light is used, the sterilization ability is weak. If deep ultraviolet light is used, the sterilization ability is reliable, but it is invisible to the human eye and there is no perceptible experience of UV sterilization. Utility Model Content

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] like Figures 1-24 As shown, in another embodiment of this utility model, a rigid gas permeable lens cleaning device includes: The lower housing 10 has an opening at its upper end. The outline of the upper opening of the lower housing 10 is a racetrack shape with semicircles at both ends and a rectangle in the middle. The top of the wall of the lower housing 10 is provided with a concave sealing groove 13, and an annular sealing ring 30 is embedded in the sealing groove 13. The upper cover plate 40 includes a flat portion 41 and a boss portion 42. The outer contour of the flat portion 41 is a racetrack shape with semicircular ends and a rectangular middle section. A sealing flange 43 protruding downwards is provided on the edge of the lower surface of the flat portion 41. The sealing flange 43 presses against the annular sealing ring 30 of the sealing groove 13 of the lower housing. The boss portion 42 protrudes upwards from the flat portion 41. The outer contour of the boss portion 42 is also racetrack-shaped. The boss portion 42 is offset to one side of the flat portion 41. A working status display area 411 is provided in the crescent-shaped area on the flat portion 41 located on the side of the boss portion 42. A concave cleaning pool 43 is provided on the upper surface of the boss portion 42. The cleaning pool 43 is a racetrack shape with semicircular ends and a rectangular middle section. The lens clamping cover 60 includes a cover plate 61, a left lens clamp 62, a right lens clamp 63, and a sealing ring 64. The outer contour of the cover plate 61 is a racetrack shape with semicircles at both ends and a rectangle in the middle. The lower surface of the cover plate 61 is provided with a racetrack-shaped ring wall 611. The outer wall of the ring wall 611 is embedded with the sealing ring 64, which is in contact with the upper part of the inner wall of the cleaning tank 43. The left lens clamp 62 is installed in the left semicircular area inside the ring wall 611 on the lower surface of the cover plate, and the right lens clamp 63 is installed in the right semicircular area inside the ring wall 611 on the lower surface of the cover plate. The left lens clamp 62 and the right lens clamp 63 are used to clamp rigid gas permeable lenses. When the rigid gas permeable lenses are installed on the left and right lens clamps, the rigid gas permeable lenses are set perpendicular to the length direction of the cover plate 61. The space between the left lens clamp 62 and the right lens clamp 63 is used to provide space for the stirring magnetic column 81 to rotate and stir. The flip cover 70 is hinged to the lower housing 10 at its rear end. The horizontal cross-section of the flip cover 70 has a racetrack-shaped outer contour. The width of the lower racetrack-shaped outer contour of the flip cover 70 is the same as the width of the upper racetrack-shaped outer contour of the lower housing 10. When the flip cover 70 is in the closed state, the flip cover 70 surrounds the boss portion 42 of the upper cover plate. The flip cover 70 is offset on the side of the lower housing near the boss portion. The working status display area 411 on the upper cover plate is located outside the flip cover 70. The magnetic stirring drive mechanism 80 includes a stirring magnetic column 81 and an external magnetic drive mechanism. The stirring magnetic column 81 is freely placed in the middle rectangular area of ​​the racetrack-shaped inner cavity of the cleaning tank 43. The external magnetic drive mechanism is used to drive the stirring magnetic column 81 to rotate in the space between the left mirror clamp 62 and the right mirror clamp 63. Circuit board 90 is fixedly mounted on the bottom surface of the upper cover plate 40; A battery is disposed in the inner cavity of the lower housing 10, and the battery is used to provide electrical energy.

[0042] The beneficial effects of adopting the above technical solution are as follows: the cleaning tank adopts a racetrack-shaped inner cavity, the lens clamping cover adopts a structure in which the left and right lens clamps clamp the lens in separate areas and the lens is set perpendicular to the cover plate. The stirring space reserved between the lens clamps, combined with the free-placed stirring magnetic column and the non-contact transmission design of the external magnetic drive mechanism, not only ensures the sealing integrity of the cleaning tank, but also drives the cleaning liquid to form a circulating water flow through the rotation of the stirring magnetic column, so as to perform all-round physical rinsing of the lens surface and efficiently remove pollutants such as tear protein and oil. The lower housing, upper cover, lens clamping cover, and flip cover all adopt a racetrack-shaped contour design with semi-circular ends and a rectangular middle section. The protrusion and flip cover are offset relative to the upper cover, with one side of the upper cover serving as the working status display area. Compared to existing technologies that typically place the working status display device on the upper surface of the top cover, no wiring is required inside the flip cover. This achieves a high degree of adaptability and compactness in the overall structure, significantly improving space utilization and making the device small, portable, and easy to store. At the same time, the unified contour design also enhances the overall integration and aesthetics. Through the sealing groove of the lower housing with a ring sealing ring and the sealing flange of the upper cover pressing against the sealing ring, a full-area sealing effect is formed, effectively preventing cleaning fluid leakage and blocking external dust and water stains from entering the lower housing, protecting electronic components such as circuit boards and batteries, and improving the stability and lifespan of the device. The overall structure has tightly fitted components and a reasonable functional layout, achieving multiple effects of cleaning, protection, and portability, while taking into account cleaning efficiency, safety, and ease of operation.

[0043] like Figure 6 As shown, in some other embodiments of this utility model, the horizontal cross-sectional outer contour of the lower housing 10 is racetrack-shaped, and the lower half of the outer surface of the side wall of the lower housing 10 has an arc-shaped transition surface that gradually tapers from top to bottom. The beneficial effect of adopting the above technical solution is to improve the aesthetics and feel of the device.

[0044] like Figure 3 , Figures 6-11 As shown, in some other embodiments of this utility model, the upper part of the rear side of the lower housing 10 is provided with a recessed lateral groove 11, the rear side and the top of the lateral groove 11 are open, and a pin insertion hole 12 is provided on the side wall of the lateral groove 11. Figure 24As shown, a hinge wall 71 extending downwards is provided on the rear side of the flip cover 70 at the position of the rectangular side in the middle of the racetrack-shaped outline. Connecting ribs 72 are provided on the left and right sides of the inner wall of the hinge wall 71, and through pin holes 73 are provided on the connecting ribs 72. When the flip cover 70 is in the closed state, the outer wall of the hinge wall 71 is flush with the rear side of the lower housing 10. It also includes a pin 77 connecting the flip cover 70 and the lower housing 10. The beneficial effects of adopting the above technical solution are: the lateral groove provides a space for the hinge wall, so that the hinge structure is hidden in the groove when the flip cover is closed; the outer wall of the hinge wall is flush with the rear side of the lower housing, so that there is no protrusion at the connection between the flip cover and the lower housing, resulting in a smoother, more integrated overall appearance and improved aesthetics.

[0045] like Figure 6 As shown, in some other embodiments of this utility model, a charging interface hole 18 that runs through the rear side wall of the lower housing 10 is provided. Both the lateral groove 11 and the charging interface hole 18 are located on the rectangular side of the racetrack-shaped outline of the lower housing 10, and are distributed left and right on the rear side of the lower housing 10. The beneficial effect of adopting the above technical solution is that the charging interface hole and the lateral groove are both arranged on the rectangular side of the racetrack shape, utilizing the straight space of the rectangular side to arrange the components, avoiding space waste caused by setting components on the semi-circular side, and improving space utilization.

[0046] like Figure 6 , Figure 12 As shown, in some other embodiments of this utility model, a concave rubber plug slot 19 is provided around the outer periphery of the charging interface hole 18, and an insertion hole 20 for inserting the umbrella-shaped connecting end 351 of the rubber plug 35 is also provided on the side of the charging interface hole 18 away from the lateral groove 11. The beneficial effects of adopting the above technical solution are: the rubber plug slot provides a precise positioning and installation position for the rubber plug, so that the rubber plug can tightly cover the charging interface hole, effectively preventing external dust and water stains from entering the charging interface and causing short circuits and oxidation, thus improving the service life of the charging interface; the insertion hole is used to fix the umbrella-shaped connecting end of the rubber plug, so that the rubber plug is integrated with the device, avoiding the loss of the rubber plug and improving the convenience of use.

[0047] Because the lower shell is injection molded, the core structure of the pin insertion holes on the left and right side walls of the side groove in the injection mold is a side core-pulling mechanism. The core pin of the pin insertion hole is pulled out laterally by the mold opening action. However, this utility model is a handheld portable cleaning device. The overall length and width of the device are limited by its dimensions. For aesthetics and ergonomics, the hinge between the flip cover and the lower shell must be located on the rear side, and the charging port must also be located on the rear side. Therefore, the distance between the left and right side walls of the side groove is only about 15mm. This results in the pin insertion holes having an insufficient axial length. After repeated opening and closing of the flip cover over a long period, the strength at the pin insertion holes is insufficient, leading to a short service life and significantly reducing the user experience. Figure 1 , Figures 6-11 , Figure 24 As shown, in order to improve the technical problem of insufficient axial depth of the pin insertion hole mentioned above, in some other embodiments of this utility model, a concave U-shaped groove 14 is provided on the bottom surface of the sealing groove 13 located on the inner side of the side wall of the side groove 11. The U-shaped groove 14 is set adjacent to the inner wall surface of the side wall of the side groove 11. The semi-circular groove at the bottom of the U-shaped groove 14 is coaxially arranged with the pin insertion hole 12 and has the same diameter. The pin 77 is inserted into the pin through hole 73 and the pin insertion hole 12 and extends to the bottom of the U-shaped groove 14. The U-shaped groove 14 is formed directly on the injection mold by a punch structure integrally machined at the corresponding position of the upper mold core. It is integrated with the forming punch of the sealing groove 13 and is formed synchronously with the sealing groove during mold closing and injection molding. While the lateral core-pulling mechanism for forming the pin insertion hole of the side groove on the mold remains unchanged, the mating length between the pin 77 and the lower housing is significantly enhanced. The beneficial effects of adopting the above technical solution are: the shaft pin is inserted into the bottom of the U-shaped groove, and the shaft pin insertion hole and the U-shaped groove cooperate with the shaft pin together, which significantly improves the stability of the shaft pin installation and extends the service life of the hinge structure.

[0048] like Figure 8 As shown, in some other embodiments of this utility model, a retaining surface 15, which is at the same level as the bottom surface of the sealing groove, is provided between the upper opening of the U-shaped groove 14 and the inner wall of the sealing groove 13. The minimum width of the retaining surface 15 is 0.3mm-0.5mm. The beneficial effects of adopting the above technical solution are: the setting of the retaining surface can ensure that the annular sealing ring and the bottom surface of the sealing groove retain a certain contact support part, which can effectively prevent external dust, water stains, etc. from entering the inner cavity of the lower housing through the U-shaped groove, avoid the annular sealing ring in the sealing groove from shifting due to the opening of the U-shaped groove, ensure the installation stability and sealing effect of the sealing ring, and maximize the axial length of the U-shaped groove in a compact space, thereby improving the fit with the shaft pin.

[0049] like Figure 3 , Figure 6As shown, in some other embodiments of this utility model, a positioning slot 16 is provided on the inner wall of the sealing groove 13, and a horizontally extending positioning latching part 31 is provided on the annular sealing ring 30, which matches the positioning slot 16. The beneficial effect of adopting the above technical solution is that it realizes the positioning of the annular sealing ring in the sealing groove, which facilitates the installation of the sealing ring.

[0050] In some other embodiments of this utility model, the top of the outer wall of the sealing groove 13 is higher than the top of the inner wall; the outer contour wall of the flat portion 41 of the upper cover plate 40 is installed along the inner wall surface of the outer wall of the sealing groove 13 of the lower housing. The beneficial effects of adopting the above technical solution are: the outer wall is higher than the inner wall, forming a stepped structure, which provides precise guidance and positioning for the installation of the upper cover plate, enabling the upper cover plate to be quickly and accurately aligned and installed with the lower housing, improving assembly efficiency, and further strengthening the connection stability between the upper cover plate and the lower housing.

[0051] like Figure 6 , Figure 14 As shown, in some other embodiments of this utility model, the inner wall surface of the lower housing 10 is provided with a plurality of hook portions 17 protruding into the inner cavity at a position below the sealing groove; the lower surface of the planar portion of the upper cover plate 40 is provided with a downwardly extending hanging hole wall 44 on the inner side of the sealing flange 43, and the hanging hole wall 44 is provided with a hook hole 441, the hook portion 17 engaging with the hook hole 441. The beneficial effect of adopting the above technical solution is that the engaging structure of the hook portion and the hook hole enables quick installation of the upper cover plate and the lower housing, and, together with the sealing structure, forms a dual connection method of "sealing + mechanical fixing", improving the connection stability of the upper cover plate and the lower housing and preventing the upper cover plate from loosening when the device vibrates.

[0052] like Figure 6 , Figure 14 As shown, in some other embodiments of this utility model, the upper sides of the hook portion 17 are provided with first reinforcing ribs 171 extending downward to the inner wall of the housing, and the upper part of the hook portion and the first reinforcing ribs 171 are provided with first guide slopes 172; the inner side wall of the hanging hole wall 44 is provided with second reinforcing ribs 442 extending upward to the bottom surface of the flat portion, and the bottom of the outer side wall of the hanging hole wall 44 is provided with second guide slopes 443. The beneficial effects of adopting the above technical solution are: the first reinforcing ribs and the second reinforcing ribs respectively strengthen the structural strength of the hook portion and the hanging hole wall, and the first guide slope and the second guide slope form a mutually cooperating guide structure, so that the hook portion can quickly and smoothly engage with the hook hole when the upper cover plate is installed.

[0053] like Figures 1-3 , Figures 13-15As shown, in some other embodiments of this utility model, the working status display area 411 of the upper cover plate 40 is provided with a vertically penetrating digital display screen opening 412 and multiple status indicator light emission holes 413; it also includes a decorative panel film 65, which is attached to the upper surface of the flat portion 41 of the upper cover plate; the decorative panel film 65 is transparent or semi-transparent, at least in the area corresponding to the digital display screen opening and the status indicator light emission holes. The beneficial effects of adopting the above technical solution are: the digital display screen opening and the status indicator light emission holes enable the information of the display screen and indicator lights to be clearly displayed, making it convenient for users to view the working mode, remaining time, battery level, and other status of the device in real time; the decorative panel film makes the surface of the upper cover plate smoother and more beautiful, while protecting the display area and the surface of the upper cover plate from scratches and water stains.

[0054] like Figure 14 As shown, in some other embodiments of this utility model, a downwardly extending light-shielding tube 414 is provided on the back of the light-emitting hole 413 of the status indicator light. The beneficial effect of adopting the above technical solution is that the light-shielding tube can effectively block the light of the indicator light from scattering in all directions, so that the light is concentrated and emitted from the light-emitting hole, thereby improving the display clarity of the indicator light.

[0055] like Figure 13 As shown, in some other embodiments of this utility model, the opening of the cleaning tank 43 is provided with a recessed positioning step surface 431, and the long side of the positioning step surface 431 is provided with a lens-retrieving clearance portion 432 extending to both sides; the areas on both sides of the long side of the bottom surface of the cover plate 61 located outside the ring wall 611 are provided with concave curved grooves 612, and the concave curved grooves 612 correspond to the positions of the lens-retrieving clearance portions 432 at the opening of the cleaning tank. The beneficial effects of adopting the above technical solution are: the positioning step surface provides a precise positioning reference for the installation of the lens clamping cover, so that the lens clamping cover can be quickly and accurately closed at the opening of the cleaning tank, ensuring the fit between the sealing ring and the inner wall of the cleaning tank; the lens-retrieving clearance portion and the concave curved groove cooperate to provide sufficient operating space for the user's fingers to insert and retrieve the lens clamping cover, improving the convenience of retrieving and retrieving the lens.

[0056] like Figure 13 As shown, in some other embodiments of this utility model, the upper surface of the protrusion 42 is further provided with a recessed stick placement groove 44. The beneficial effects of adopting the above technical solution are: the stick placement groove provides a dedicated storage space for the orthokeratology lens stick, allowing the stick and cleaning device to be stored together in one piece, preventing the stick from being lost, and making it convenient for users to pick it up at will, thus improving ease of use.

[0057] like Figure 5As shown, in some other embodiments of this utility model, a lower magnetic block 48 is fixedly installed on the front side of the bottom surface of the upper cover plate 40; an upper magnetic block 74 is provided on the inner side of the front wall of the flip cover 70.

[0060] like Figures 13-15 As shown, in some other embodiments of this utility model, light guide blocks 433 are respectively embedded in the side walls of the two long sides of the cleaning tank 43. The light guide blocks 433 and the upper cover plate 40 are integrally injection molded. The light-receiving surface 4331 of the light guide block 433 faces the light-generating device, and the light-emitting surface 4332 of the light guide block 433 faces the inside of the cleaning tank 43.

The beneficial effects of adopting the above technical solution are: this size design makes the overall device compact, suitable for hand-held grip, easy to carry and store, and adaptable to the small space requirements of teenagers' school bags, desktops, etc.; at the same time, the size of the cleaning tank is compatible with the specifications of rigid gas permeable lenses, minimizing the amount of cleaning solution used while ensuring sufficient cleaning space for the lenses, thus saving cleaning costs.

[0065] like Figure 16 As shown, in some other embodiments of this utility model, the upper surface of the motor bracket 82 is provided with a positioning ring 821 surrounding the motor bracket mounting post 47, and the motor bracket 82 is locked and fixed to the motor bracket mounting post 47 on the bottom surface of the upper cover plate by screws. The beneficial effect of adopting the above technical solution is that the positioning ring provides precise circumferential positioning for the installation of the motor bracket, ensuring the alignment accuracy between the motor bracket and the upper cover plate, so that the output shaft of the drive motor can be precisely aligned with the center of the bottom surface of the cleaning tank.

[0066] like Figure 16 , Figure 17 As shown, in some other embodiments of this utility model, the magnetic block holder 841 is provided with two magnetic block slots for setting the first magnetic block 842 and the second magnetic block 843. The first magnetic block 842 and the second magnetic block 843 are inserted from the bottom of the magnetic block slots. The upper part of the magnetic block slots is provided with a stop step surface, and the middle of the stop step surface is provided with a magnetic through hole 8411. Claws 8412 for locking the lower surfaces of the first magnetic block and the second magnetic block are provided on the front and rear sides of the magnetic block slots. The beneficial effects of adopting the above technical solution are as follows: the magnetic block slot provides precise installation positioning for the first and second magnetic blocks, ensuring the symmetry and magnetic pole direction of the two magnetic blocks and improving the uniformity of the rotating magnetic field; the bottom insertion method facilitates the assembly of the magnetic blocks; the stop step surface forms an upward limit on the magnetic blocks, preventing the magnetic blocks from coming off upward during rotation; the magnetic opening ensures that the magnetic force can be transmitted to the cleaning tank without obstruction, improving the magnetic transmission efficiency; the front and rear claws form a downward clamping and fixing of the magnetic blocks, which, together with the stop step surface, achieves bidirectional fixation of the magnetic blocks from top to bottom, preventing the magnetic blocks from shifting or falling off during rotation and vibration, and improving the stability of the magnetic block installation.

[0067] like Figure 16 , Figure 17As shown, in some other embodiments of this utility model, the opposing surfaces of the front and rear jaws 8412 are provided with inclined surfaces 8413 to facilitate pressing the first and second magnetic blocks, and a narrow groove 8414 is provided between the lateral part of the root of the jaw 8412 and the wall of the magnetic block groove. The beneficial effects of adopting the above technical solution are: the inclined surfaces on the jaws provide guidance for pressing the magnetic blocks, so that the magnetic blocks can be pressed into the magnetic block groove quickly and smoothly; the narrow groove gives the jaws a certain elastic deformation capability, so that the jaws can open appropriately when pressing the magnetic blocks, and automatically reset and lock after the magnetic blocks are in place, realizing the elastic locking of the magnetic blocks, improving the firmness of the locking and the assembly efficiency.
