These lenses need to be worn daily and thoroughly cleaned to remove contaminants such as tear proteins, oils, and dust from the lens surface, thus avoiding the risk of eye infections and ensuring the optical performance and lifespan of the lenses.

[0003] Existing rigid gas permeable lens cleaning devices are either purely manual with limited functionality, only capable of basic rinsing or wiping, resulting in poor cleaning effects; or multi-functional cleaning devices are bulky, loosely structured, take up a lot of desktop space, are inconvenient to carry and store, and cannot meet the needs of teenagers in different scenarios such as home and school.

[0004] In addition, while the rigid gas permeable lens cleaning device is designed to be compact, it also limits the space for the hinge structure of the flip cover. How to improve the service life of the flip cover hinge structure within a compact space will be an important factor in improving the user experience. Summary of the Invention

The stirring magnetic column is freely placed in the middle rectangular area of ​​the racetrack-shaped inner cavity of the cleaning tank. The external magnetic drive mechanism is used to drive the stirring magnetic column to rotate in the space between the left and right lens clamps. A circuit board is fixedly mounted on the bottom surface of the upper cover plate. A battery is disposed in the inner cavity of the lower housing and is used to provide electrical energy.

[0012] Furthermore, the outer contour length of the lower housing is 100±10mm and the width is 70±10mm; the outer contour length of the flip cover is 80±10mm and the width is 70±10mm; the length of the cleaning pool is 35±5mm and the width is 25±5mm.

[0013] Furthermore, an upper magnetic block is provided on the inner side of the front wall of the flip cover; a lower magnetic block is fixedly installed on the front side of the bottom surface of the upper cover plate.

[0014] Furthermore, the upper cover plate's working status display area has a vertically extending digital display screen opening and multiple status indicator light emission holes; light guide blocks are respectively embedded in the side walls of the two long sides of the cleaning tank, and the light guide blocks are integrally injection molded with the upper cover plate.

The magnetism of the upper end of the first magnetic block is opposite to that of the upper end of the second magnetic block.

[0016] The beneficial effects of this invention are as follows: The flip-top hinge structure has a U-shaped groove on the bottom surface of the sealing groove, increasing the mating length between the pin and the lower housing. The U-shaped groove is formed directly on the injection mold by a punch structure integrally machined at the corresponding position of the upper mold core, and is integrated with the forming punch of the sealing groove, forming synchronously with the sealing groove during mold closing and injection molding.

[0017] The cleaning tank features a racetrack-shaped inner cavity, and the lens clamping cover uses left and right lens clamps to clamp the lenses in separate areas. 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 enables the cleaning fluid to form a circulating water flow through the rotation of the stirring magnetic column, which physically washes the lens surface in all directions, effectively removing contaminants such as tear proteins and oils.

[0018] The lower shell, upper cover, lens clamping cover, and flip cover all adopt a racetrack-shaped outline design with semi-circular ends and a rectangle in the middle. The protrusion and flip cover are offset relative to the upper cover. One side of the upper cover becomes the working status display area. Compared with the existing technology that usually sets the working status display device on the upper surface of the top cover, there is no need for wiring inside the flip cover, which realizes the compactness of the overall structure, greatly improves the space utilization, and makes the device small in size and easy to carry and store. At the same time, the unified outline design also improves the integration and aesthetics of the overall appearance. Attached Figure Description

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] As shown in Figures 1-3, a rigid gas permeable lens cleaning device includes a lower housing 10 and a flip cover 70, the flip cover 70 being hinged to the lower housing 10.

[0047] As shown in Figures 3 and 6-11, in some other embodiments of the present invention, the upper part of the rear side of the lower housing 10 is provided with a concave 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. As shown in Figure 24, the rear side of the flip cover 70 is provided with a downwardly extending hinge wall 71 corresponding to the position of the middle rectangular side of the racetrack-shaped outline. Connecting ribs 72 are provided on the left and right sides of the inner wall surface of the hinge wall 71, and the connecting ribs 72 are provided with through pin holes 73. When the flip cover 70 is in the closed state, the outer wall surface of the hinge wall 71 is flush with the rear side of the lower housing 10. A pin 77 connecting the flip cover 70 and the lower housing 10 is also included. The beneficial effects of adopting the above technical solution are: the side 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 surface of the hinge wall is flush with the rear side of the lower shell, so that there is no protrusion at the connection between the flip cover and the lower shell, the overall appearance is flatter and more integrated, and the aesthetics are improved.

[0048] Since 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 invention is a handheld portable cleaning device. The overall length and width of the device are limited by size. For aesthetics and ergonomics, the hinge between the flip cover and the lower shell must be located on the rear side, and the charging interface 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 axial length of the formed pin insertion hole being too short. After repeated opening and closing of the flip cover for a long time, the strength of the pin insertion hole is insufficient, the service life is short, and it will significantly reduce the user experience. As shown in Figures 1, 6-11, and 24, to improve the technical problem of insufficient axial depth of the pin insertion hole mentioned above, in some embodiments of the present invention, 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 lateral groove 11. The U-shaped groove 14 is arranged adjacent to the inner wall surface of the side wall of the lateral 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 injection molding. While the lateral core-pulling mechanism for forming the pin insertion hole of the lateral 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.

[0049] The following are durability test data on the opening and closing damping retention capability of the flip cover for two samples: one without a U-groove and one with a U-groove. From the test data above, it can be seen that the added U-groove structure can significantly improve the service life of the flip cover hinge structure and enhance the opening and closing damping retention capability of the flip cover.

[0050] As shown in Figures 1-24, a rigid gas permeable (RGP) lens cleaning device includes: a lower housing 10 with an opening at its upper end, the upper opening of the lower housing 10 having a racetrack-shaped profile with semicircular ends and a rectangular middle section; a recessed sealing groove 13 is provided at the top of the wall of the lower housing 10, and an annular sealing ring 30 is embedded in the sealing groove 13; an upper cover plate 40, including a flat portion 41 and a boss portion 42, the outer contour of the flat portion 41 having a racetrack-shaped profile with semicircular ends and a rectangular middle section, and a downwardly protruding sealing flange 43 is provided on the edge of the lower surface of the flat portion 41, the sealing flange 43 pressing against the annular sealing ring 30 of the sealing groove 13 of the lower housing; the boss portion 42 protrudes upward 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 on the flat portion 41 in a crescent-shaped area on the side of the boss portion 42. The upper surface of the boss portion 42 is provided with a recessed cleaning pool 43, which is racetrack-shaped 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 racetrack-shaped with semicircular ends and a rectangular middle section. 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 fitted with a sealing ring 64, which is in contact with the upper part of the inner wall of the cleaning pool 43. The left lens clip 62 is installed in the left semicircular area inside the annular wall 611 on the lower surface of the cover plate, and the right lens clip 63 is installed in the right semicircular area inside the annular wall 611 on the lower surface of the cover plate. The left lens clip 62 and the right lens clip 63 are used to hold the rigid gas permeable lens. When the rigid gas permeable lens is installed on the left lens clip and the right lens clip, the rigid gas permeable lens is set perpendicular to the length direction of the cover plate 61. The space between the left lens clip 62 and the right lens clip 63 provides 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-sectional outer contour of the flip cover 70 is racetrack shaped. 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. The widths are the same; when the flip cover 70 is in the closed state, the flip cover 70 surrounds the boss portion 42 of the upper cover plate, and 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; the circuit board 90 is fixedly installed on the bottom surface of the upper cover plate 40; the battery is disposed in the inner cavity of the lower housing 10, and the battery is used to provide electrical energy.

[0051] 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.

[0052] As shown in Figure 6, in some other embodiments of the present invention, the horizontal cross-sectional outer contour of the lower housing 10 is racetrack-shaped, and the lower half of the outer surface of the sidewall 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.

[0053] As shown in Figure 6, in some embodiments of the present invention, a charging interface hole 18 extending 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 profile of the lower housing 10, and are distributed left-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.

[0054] As shown in Figures 6 and 12, in some embodiments of the present invention, 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.

[0055] As shown in Figure 8, in some embodiments of the present invention, 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.

[0056] As shown in Figures 3 and 6, in some embodiments of the present invention, 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, the positioning latching part 31 matching 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, facilitating the installation of the sealing ring.

[0057] In other embodiments of the present invention, 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.
