Description

Technical Field

[0001] This utility model relates to the field of contact lens placement, and more particularly to a contact lens auxiliary humidification device. Background Technology

[0002] Contact lenses are thin, transparent optical lenses that adhere directly to the cornea of ​​the eye. They are used to correct myopia, hyperopia, astigmatism, or improve appearance. Made of highly oxygen-permeable flexible materials, they naturally adhere to the cornea through tears, providing clear vision without affecting daily activities. They are available in daily and monthly disposable versions and require strict cleaning and care to avoid infection.

[0003] When placing contact lenses, they are usually put into a special case. The inside of the case has a raised round frame, and a moistening liquid is added inside. The contact lens is placed inside the round frame. Because the lens itself is small and it is stuck inside the frame, it is very inconvenient to take out and put in, which affects the user experience. In addition, the need to put fingers into the liquid to remove the lens raises hygiene issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary humidification device for contact lenses, thereby improving the convenience of handling and wearing contact lenses and enhancing the safety of contact lens placement.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A contact lens humidification aid includes a support frame, a flip-top cover rotatably connected to the top of the frame, a placement platform fixedly connected inside the frame, support rings fixedly connected to the two side slots of the placement platform, an uplift filter plate abutting the top of the support rings, a sealing sleeve fixedly connected to the front center of the placement platform, the outer side of the sealing sleeve fixedly connected to the front of the frame, a pressing post slidably connected inside the sealing sleeve, an outward pushing triangular block fixedly connected to the rear end of the pressing post, an upward pushing assembly installed inside the placement platform, and pull-back reset assemblies installed inside the two side slots of the placement platform for easy removal of contact lenses. A compression limiting assembly is installed inside the flip-top cover to protect the contact lenses.

[0007] Furthermore, the compression limiting assembly includes limiting posts fixed on both sides inside the flip cover frame, with limiting protective pads fixedly connected to the bottom ends of the limiting posts, and the outer sides of the limiting protective pads respectively attached to the top of the slots on both sides of the placement platform.

[0008] Furthermore, the upward pushing assembly includes traction plates that slide on both sides inside the placement platform. Each traction plate is fixedly connected to an outer push column, and each outer push column is fixedly connected to an outer push seat. Each outer push seat is rotatably connected to a flipping link. The bottom end of the upward-lifting filter plate is fixedly connected to a fixed seat, and the top ends of the flipping link are rotatably connected to the inside of the fixed seat.

[0009] Furthermore, the pull-back reset assembly includes a fixed circular sleeve located inside the slots on both sides of the placement platform. An upward push column is slidably connected inside the fixed circular sleeve. The top end of the upward push column is fixedly connected to the middle of the bottom end of the lifting filter plate. The bottom end of the upward push column is connected to the inside of the fixed circular sleeve through a reset tension spring.

[0010] Furthermore, inner guide covers are fixedly connected to both sides of the top of the placement platform to limit the contact lens from protruding.

[0011] Furthermore, an external drain pipe is fixedly connected to the right side of the placement platform. The outside of the external drain pipe penetrates the outside of the placement frame. An anti-blocking block is nested inside the external drain pipe. A connecting slot is opened on both sides of the bottom inside the placement platform.

[0012] Furthermore, a sealing gasket is fixedly connected to the top of the placement frame to achieve sealing of the interior of the placement frame.

[0013] Furthermore, a soft rubber pad is fixedly connected to the top of the raised filter plate to protect the contact lenses.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, pressing the pressing column pushes the outward-pushing triangular block to the rear, thereby generating an outward squeezing force on the traction plate. The outward-pushing column is then squeezed outward, thereby pushing the flipping linkage to flip and push the lifting filter plate upward, protruding the contact lens located inside the placement platform. This improves the convenience of taking out and wearing contact lenses and enhances the hygiene and safety of taking them out.

[0016] 2. In this utility model, when the cover is flipped and closed, the limiting post exerts a downward squeezing force on the limiting protective pad, thereby squeezing the limiting protective pad into the slots on both sides of the placement platform. At this time, the contact lens is restricted inside by the soft rubber pad and the limiting protective pad. When the outside of the box shakes, the lens is squeezed and restricted, thereby preventing the lens from colliding with the frame and improving the safety of contact lens placement.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1-3 This utility model provides an embodiment of an auxiliary humidification device for contact lenses, comprising a placement frame 1 for support, a flip cover frame 2 rotatably connected to the top of the placement frame 1, a placement platform 7 fixedly connected inside the placement frame 1, support rings 14 fixedly connected inside the slots on both sides of the placement platform 7, an upward filter plate 13 abutting the top of the support rings 14, a sealing sleeve 4 fixedly connected to the middle of the front end of the placement platform 7, the outer side of the sealing sleeve 4 fixedly connected to the front end of the placement frame 1, and a pressing post 3 slidably connected inside the sealing sleeve 4. (See reference...) Figure 4The rear end of the pressing column 3 is fixedly connected to an outward pushing triangular block 24. An upward pushing assembly is installed inside the placement platform 7. Retractable reset assemblies are installed inside the slots on both sides of the placement platform 7 to facilitate easy removal of contact lenses. A limiting compression assembly is installed inside the flip cover frame 2 to protect the contact lenses. The upward pushing assembly includes traction plates 22 that slide on both sides inside the placement platform 7. Outward pushing columns 21 are fixedly connected to the outer sides of the traction plates 22. Outward pushing seats 20 are fixedly connected to the outer sides of the outward pushing columns 21. A flipping connecting rod 19 is rotatably connected to the outer side of the outward pushing seats 20. A fixed seat 18 is fixedly connected to the bottom end of the lifting filter plate 13. The top ends of the flipping connecting rod 19 are respectively... The corresponding rotational connection is inside the fixed base 18. The pull-back reset assembly includes a fixed round sleeve 16 located inside the slots on both sides of the placement platform 7. The fixed round sleeve 16 is slidably connected to an upper push column 15. The top of the upper push column 15 is fixedly connected to the middle of the bottom of the lifting filter plate 13. The bottom of the upper push column 15 is connected to the inside of the fixed round sleeve 16 through a reset spring 17. The top two sides of the placement platform 7 are fixedly connected to an inner guide cover 9 to limit the contact lens from being ejected. The right side of the placement platform 7 is fixedly connected to an outer drain pipe 6. The outer side of the outer drain pipe 6 penetrates the outer side of the placement frame 1. An anti-blocking block 5 is nested inside the outer drain pipe 6. The bottom two sides of the placement platform 7 are provided with a connecting slot 23.

[0025] When the user needs to retrieve the internal contact lens, they simply flip the cover frame 2 outwards. This action simultaneously applies inward pressure to the pressing post 3. During this process, the rear inclined surface of the outward pushing triangle 24 contacts the front inclined surface of the traction plate 22, and the angle between the outward pushing triangle 24 and the inclined surface of the traction plate 22 is 45°±5°. By optimizing the force transmission, the smoothness of ejection is improved, pushing the traction plate 22 to unfold and move to both sides. The unfolding action of the traction plate 22 further drives the outward pushing post 21 to move outwards, while simultaneously pushing the outward pushing seat 20 to move outwards in sync. This series of mechanical transmissions generates an upward thrust through the lower side of the flipping linkage 19, causing the flipping action to occur. The linkage 19 completes the flipping action, and the flipping linkage 19 ultimately applies an upward pushing force to the lifting filter plate 13, causing it to move upward and push out the contact lens. During the upward pushing of the lifting filter plate 13, the upper push post 15 moves upward, and the reset spring 17 generates a downward pulling force on the upper push post 15. The reset spring 17 has a wire diameter of 0.3mm and a preload of 0.8N, which generates resistance to the upward push of the lifting filter plate 13, ensuring the stability of the lens being pushed out and making it easy for the user to take it out. When the pressing post 3 is released, the reset spring 17 will pull the upper push post 15 downward to reset, so that the lifting filter plate 13 is reattached to the top of the support ring 14 and remains immersed in the liquid.

[0026] Reference Figure 1 and Figure 2The compression limiting assembly includes limiting posts 12 fixed on both sides inside the flip cover frame 2. The bottom end of the limiting posts 12 is fixedly connected to a limiting protective pad 11. The outer sides of the limiting protective pad 11 are respectively attached to the top of the slots on both sides of the placement platform 7. The top end of the placement frame 1 is fixedly connected to a sealing pad 8 to achieve sealing inside the placement frame 1. The top end of the lifting filter plate 13 is fixedly connected to a soft rubber pad 10 to achieve protection for contact lenses.

[0027] After the contact lens is placed inside the housing 1, when the flip cover 2 is closed, the limiting post 12 will press down on the limiting protective pad 11, causing it to embed into the slots on both sides of the placement platform 7. At this time, the contact lens is stably restricted between the placement soft rubber pad 10 and the limiting protective pad 11, forming a reliable fixing structure. When the housing is subjected to external shaking or impact, the lens will be uniformly buffered and restrained, effectively preventing it from colliding with the housing, thereby significantly improving the safety and stability of contact lens storage.

[0028] Working principle: When removing the internal contact lens, the flip cover frame 2 is flipped outwards. At this time, an inward pressing force is generated on the pressing post 3, and the rear inclined surface of the outward pushing triangular block 24 contacts the front inclined surface of the traction plate 22, thereby squeezing the traction plate 22 outwards. The traction plate 22 exerts an outward force on the outward pushing post 21, thereby moving the outward pushing seat 20 outwards at the same time, and generating a pushing force on the lower side of the flipping linkage 19. The flipping linkage 19 flips accordingly, thereby generating an upward pushing force on the lifting filter plate 13, pushing the contact lens outwards. During the upward pushing of the lifting filter plate 13, the upward pushing post 15 moves upwards, and the return spring 17 generates a downward pulling force on the upward pushing post 15, pushing the lifting filter plate 13 outwards. The upward push of the 3rd column generates resistance, ensuring the stability of the lens ejection and facilitating user retrieval. Releasing the pressing force of the 3rd column causes the return spring 17 to exert a downward pulling force on the upward push column 15, thereby pressing the upward filter plate 13 against the top of the support ring 14 and immersing it in liquid. When the contact lens is placed inside the placement frame 1, with the flip-top frame 2 closed, the limiting column 12 exerts a downward squeezing force on the limiting protective pad 11, thereby squeezing the limiting protective pad 11 into the slots on both sides of the placement platform 7. At this time, the contact lens is restricted inside by the placement soft rubber pad 10 and the limiting protective pad 11. When the outside of the case shakes, the lens is squeezed and restricted, thereby preventing the lens from colliding with the frame and improving the safety of contact lens placement.
