[0041] Reference Figure 1The present invention provides a contact lens cleaning device, comprising: a cup body 1, a platinum neutralization ring 2, a cup cover, and a left lens clamp 3 and a right lens clamp 4 for clamping the lens;

[0042] The cup body 1 is provided with an external thread at the cup mouth. The platinum neutralization ring 2 is located inside the cup body 1. The left lens clip 3 and the right lens clip 4 are respectively connected to the cup cover to form a whole. The cup cover is screwed on the cup mouth of the cup body 1 by threaded assembly, and the left lens clip 3 and the right lens clip 4 are both located in the cup body 1 and above the platinum neutralization ring 2.

[0043] When cleaning the lenses, unscrew the cup cover, install the left lens and the right lens on the left lens clip 3 and the right lens clip 4 respectively, and then when the cup cover is closed, the left lens clip 3 and the right lens clip 4 directly bring the left lens and the right lens into the cup body 1, and use the hydrogen peroxide in the bottle to clean the lenses.

[0044] Reference Figure 2-3 Furthermore, the cup cover in this embodiment includes an inner cover 5 and an outer cover 6, the left lens clip 3 and the right lens clip 4 are both connected to the inner top surface of the inner cover 5; the inner side of the inner cover 5 is provided with an internal thread adapted to the external thread arranged at the cup mouth, the inner cover 5 is provided with a vent hole and a waterproof breathable membrane 7 covering the vent hole, the outer top surface of the inner cover 5 is provided with a fitting portion A51; the inner top surface of the outer cover 6 is provided with a fitting portion B61; the outer cover 6 wraps the inner cover 5 inside thereof and can rotate relative to the inner cover 5, and the outer wall of the outer cover 6 is in contact with the inner cover 5. An exhaust groove 8 is provided at the joint of the inner wall of the cover 5; the top of the outer cover 6 has the ability to deform. Under normal conditions, there is a distance between the interlocking portion B61 arranged on the inner side of the top of the outer cover 6 and the interlocking portion A51 arranged on the outer top surface of the inner cover 5 to maintain a separation state. When the top of the outer cover 6 is under pressure, the top of the outer cover 6 deforms inwardly so that the interlocking portion B61 arranged on the inner side of the top of the outer cover 6 is engaged with the interlocking portion A51 arranged on the outer top surface of the inner cover 5, thereby making the outer cover 6 and the inner cover 5 enter a circumferentially fixed connection state.

[0045] During the lens cleaning operation, the gas in the cup enters between the inner cover 5 and the outer cover 6 through the vent holes and the waterproof breathable membrane 7 on the inner cover 5, and is discharged from the port of the cup cover along the exhaust groove 8. This design does not show the vent holes and the waterproof breathable membrane 7 in appearance, making the appearance more simple and beautiful. At the same time, after the cleaning is completed, when opening the cup cover, the outer cover 6 is pressed on the top while twisting the outer cover 6 so that the interlocking part B61 is interlocked with the interlocking part A51, and the inner cover 5 rotates with the twisting of the outer cover 6, thereby completing the opening operation. When the pressure on the top of the outer cover 6 is released, the top of the outer cover 6 is reset, and the interlocking part B61 is separated from the interlocking part A51. At this time, the inner cover 5 no longer rotates with the twisting of the outer cover 6, that is, when the outer cover 6 is rotated, the inner cover 5 does not move, which can prevent the container cover from being accidentally opened and improve the safety of use.

[0046] Furthermore, the matching modes of the interlocking portion A51 and the interlocking portion B61 in this embodiment include at least the following three modes:

[0047] The first one is that the interlocking part A51 is a protruding structure arranged on the outer top surface of the inner cover 5, and the interlocking part B61 is a groove structure arranged on the inner top surface of the outer cover 6. In the interlocking state, the interlocking part A51 is embedded in the interlocking part B61, so that when the outer cover 6 is twisted, the interlocking part B61 pushes the interlocking part A51 to rotate the inner cover 5.

[0048] The second type is that the interlocking part A51 is a groove structure arranged on the outer top surface of the inner cover 5, and the interlocking part B61 is a convex structure arranged on the inner top surface of the outer cover 6. In the interlocking state, the interlocking part B61 is embedded in the interlocking part A51, so that when the outer cover 6 is twisted, the interlocking part B614 pushes the interlocking part A51 to rotate the inner cover 5.

[0049] The third type is that the interlocking part A51 is a protruding structure arranged on the outer top surface of the inner cover 5, and the interlocking part B61 is a protruding structure arranged on the inner top surface of the outer cover 6. In the interlocking state, the interlocking part A51 is on one side of the rotation direction of the interlocking part B61, so that when the outer cover 6 is twisted, the interlocking part B61 pushes the interlocking part A51 to rotate the inner cover 5.

[0050] Furthermore, there are multiple interlocking parts A51, which are evenly distributed circumferentially on the outer top surface of the inner cover 5; the number of interlocking parts B61 is consistent with the number of interlocking parts A51, and are evenly distributed circumferentially on the inner top surface of the outer cover 6, so as to increase the driving effect of the outer cover 6 on the inner cover 5 when the outer cover 6 is twisted.

[0051] The outer cover 6 in this embodiment is sleeved on the inner cover 5 and is rotatably connected with the inner cover 5, so that the outer cover 6 wraps the inner cover 5 inside and can rotate relative to the inner cover 5. In addition, an undercut structure 63 is provided on the inner side of the port of the outer cover 6, and the undercut structure 63 is stuck on the edge of the port of the inner cover 51, so as to prevent the inner cover 5 from slipping out of the outer cover 6 by using the undercut structure 63. A limiting ring extending inward is provided on the inner side of the outer cover 6, and a limiting groove is provided on the outer periphery of the inner cover 5, and the limiting ring is located in the limiting groove to form a rotating assembly of the outer cover 6 and the inner cover 5, and ensure the stability of the assembly of the two. The outer side wall of the outer cover 6 is evenly distributed with a number of anti-slip protrusions in the circumferential direction to increase the friction of the peripheral wall of the outer cover 6, thereby facilitating the twisting of the outer cover 6.

[0052] In addition, in this embodiment, a sealing structure is provided at the contact point between the cup body 1 and the inner cover 5 to ensure the sealing between the two.

[0053] Reference Figure 4The sealing structure includes a main sealing rib 57 arranged on the inner top surface of the inner cover 5. The main sealing rib 57 is an annular structure and a distance is reserved between the inner cover 5 and the peripheral wall. When the inner cover 5 is screwed onto the cup body 1, the main sealing rib 57 is inserted into the inner side of the cup mouth of the cup body 1 and fits tightly with the inner wall of the cup mouth, thereby forming a seal.

[0054] Reference Figure 5 The sealing structure also includes a secondary sealing rib 58 arranged on the inner top surface of the inner cover 5, and a sealing groove arranged on the port of the cup body 1; the sealing groove is an annular groove arranged along the circumference of the port of the cup body 1; the secondary sealing rib 58 is an annular structure, and is coaxially arranged between the main sealing rib 57 and the peripheral wall of the inner cover 5; when the inner cover 5 is screwed onto the cup body 1, the main sealing rib 57 is inserted into the inner side of the cup mouth of the cup body 1 and fits tightly with the inner wall of the cup mouth, thereby forming a first seal, and the secondary sealing rib 58 is inserted into the sealing groove and fits tightly with the sealing groove, thereby forming a second seal.

[0055] Reference Figure 6 Furthermore, a pressure surface 571 protruding outward is provided on the outside of the main sealing rib 57 to increase the sealing effect with the inner wall of the cup mouth.

[0056] In addition, in this embodiment, an inner groove 56 is provided on the outer top surface of the inner cover 5, and the vent hole is provided on the inner side of the inner groove 56, and the waterproof breathable membrane 7 is fixed in the inner groove 56. This structural design facilitates the installation of the waterproof breathable membrane 7, and the inner groove 56 can limit the installed waterproof breathable membrane 7, thereby ensuring the firmness of the installation of the waterproof breathable membrane 7.

[0057] Furthermore, the inner top surface of the outer cover 6 is provided with a plurality of protrusions 62 evenly distributed around the outer periphery of the vent holes, and all the protrusions 62 are located inside the inner groove 56 and rest against the waterproof breathable membrane 7 to press the waterproof breathable membrane 7 and ensure the firmness of the installation of the waterproof breathable membrane 7.

[0058] In this embodiment, the outer cover 6 is made of plastic, and its top is a thin-walled structure so that its top has deformation capability.

[0059] Reference Figure 7-9The inner top surface of the inner cover 5 is provided with a left embedding groove 52, a right embedding groove 53, a left assembly part 54 arranged inside the left embedding groove 52, and a right assembly part 55 arranged inside the right embedding groove. The left lens clip 3 includes a left connecting rod 31, a left clamping part 32 arranged at one end of the left connecting rod 31, a left embedding block 33 arranged at the other end of the left connecting rod 31, and a left assembly hole arranged at the end of the left embedding block 33; the left embedding block 33 is interference-fitted in the left embedding groove 52, and the left assembly part 54 is interference-fitted in the left assembly hole. The right lens clip 4 includes a right connecting rod 41, a right clamping part 42 arranged at one end of the right connecting rod 41, a right embedding block 43 arranged at the other end of the right connecting rod 41, and a right assembly hole arranged at the end of the right embedding block 43; the right embedding block 43 is interference-fitted in the right embedding groove 53, and the right assembly part 55 is interference-fitted in the right assembly hole. This structure enables the left lens clip 3, the right lens clip 4 and the cup cover to form a two-way assembly, thereby increasing the stability of the assembly while achieving detachable assembly.

[0060] Furthermore, the left clamping part 32 and the right clamping part 42 in this embodiment both have a clamping groove 9, and the clamping groove 9 includes a left groove cavity and a right groove cavity with groove openings facing each other and a reserved spacing therebetween, and the left groove cavity and the right groove cavity have an open end at one end away from the cup cover, and the groove bottoms of the left groove cavity and the right groove cavity both include a concave arc segment with both ends facing the inner side of the two, and a convex arc segment with both ends facing the outer side of the two, and the convex arc segment is located at the port of its open end and connected with the corresponding concave arc segment. This not only facilitates the lens to slide into the clamping groove 9 along the convex arc segment, but also can more effectively prevent the lens from sliding out of the clamping groove 9. In addition, a through hole 10 is provided on the concave arc segment, so that the lens cleaning liquid in the bottle can enter the groove cavity through the through hole 10 to avoid cleaning dead corners.

[0061] In addition, in order to avoid confusion between the left and right lenses of the photo during cleaning, the present embodiment provides distinguishing marks on the left lens clip 3 and the right lens clip 4. The distinguishing marks can be colors. For example, the colors of the left and right lens clips 4 and the right lens clip 4 are different, and the two can be distinguished by the difference in color. Alternatively, they can be distinguished by different symbols, such as setting different symbols on the left lens clip 3 and the right lens clip 4 to distinguish the two.

[0062] Referring to 10, the platinum neutralization ring 2 in this embodiment includes a ring body 21, and a plurality of blades 22 uniformly distributed in the circumference and integrally formed on the inner ring surface of the ring body 21, and the ends of all blades 22 are facing the center of the neutralization ring. Since the neutralization ring is placed in the lens cleaning cup, it is necessary to maintain a gap of more than 1mm with the inner wall and bottom of the bottle body, and cannot contact the lens clamp, so the surface area cannot be increased by increasing the outer size of the product, and the thickness of the outer teeth of the traditional gear-shaped neutralization ring structure cannot be too thin due to molding requirements, and then the number of outer teeth cannot be designed too much. The present invention has the blades 22 built-in, so that the thickness of the blades 22 can be designed to be thinner and the number of blades 22 can be designed to be more without changing the specifications of the neutralization ring, thereby increasing the surface area of ​​the entire neutralization ring. And the bubbles generated by the reaction are diffused from the inside of the neutralization ring to the outside, that is, the bubble density on the inside of the neutralization ring is the largest, so that the lens in the center can be better cleaned.

[0063] Furthermore, the blades 22 in this embodiment are wavy, S-shaped, or Z-shaped to further increase the surface area of ​​the neutralization ring. The blades 22 in this embodiment are of equal thickness, so that the closer the blades 22 are to their inner annular surface, the larger the spacing between the blades 22. Since during the cleaning process, the contact surface of the neutralization ring near its inner annular surface with hydrogen peroxide is greater than the contact surface near the end of the blade 22, this structural design of equal thickness of the blades 22 can ensure that during the cleaning process, the spacing between the blades 22 near the inner annular surface is sufficient to ensure that the bubbles overflow quickly. In addition, in this embodiment, the end of the blade 22 is set as an arc surface to ensure the smoothness of the line at its end.

[0064] Furthermore, the inner bottom surface of the cup body 1 is provided with a plurality of circumferentially arranged lower ribs, and the inner wall of the cup body 1 near its bottom is provided with a plurality of circumferentially arranged lateral ribs; the lower end surface of the platinum neutralization ring 2 is supported by the lower ribs, and its outer wall is against the lateral ribs. The lower ribs and the lateral ribs are used to maintain a gap between the platinum neutralization ring 2 and the bottom surface of the cup bottom and the inner wall of the side wall, so as to ensure that the surface of the platinum neutralization ring 2 is completely exposed to the cleaning liquid. In order to make the platinum neutralization ring 2 slide smoothly to the bottom along the lateral ribs, the top of the lateral ribs and the inner wall of the cup body 1 are smoothly transitioned or inclined.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
