Description

Technical Field

[0001] The utility model relates to the technical field of lens cleaning, in particular to a lens cleaning cup. Background Art

[0002] Orthokeratology lenses are made of gas-permeable rigid contact lens material, commonly known as RGP. Orthokeratology lenses are a special type of RGP lens. While standard RGP lenses are used for vision correction, orthokeratology lenses are used for "correction," improving vision by changing the corneal morphology. However, if orthokeratology lenses are not cleaned, they can lead to eye infections. Therefore, regular lens cleaning is essential.

[0003] Contact lens cleaning cups are a commonly used lens cleaning device. However, existing contact lens cleaning cups on the market have complex waterproofing and venting designs, requiring gaskets, gears, and other components, significantly increasing costs. Furthermore, the vent holes can leak out, making them unsightly. Utility Model Content

[0019] Figure 3 This is an appearance diagram of a lens cleaning cup proposed in the utility model. DETAILED DESCRIPTION

[0020] Reference Figure 1-3 The present invention provides a lens cleaning cup, comprising: a cup body 1 and a cup cover, wherein the cup cover comprises an inner cover 2 and an outer cover 3, wherein:

[0021] The inner lid 2 has an internal thread on its inner side and an external thread at the mouth of the cup. The inner lid 2 is screwed onto the mouth of the cup body 1 in a threaded fit. The inner lid 2 is provided with a vent hole 21 and a waterproof breathable membrane 4 covering the vent hole 21. The outer top surface of the inner lid 2 is evenly distributed with a number of bosses 22.

[0022] The outer cover 3 is rotatably mounted on the inner cover 2, and a gap is provided between the inner top surface of the outer cover 3 and the outer top surface of the inner cover 2. The inner top surface of the outer cover 3 is provided with an outer groove 31 corresponding to each boss 22. The top of the outer cover 3 has the ability to deform so that when the top of the outer cover 3 is pressed, it can be pressed against the top of the inner cover 2, so that the outer groove 31 on the outer cover 3 can clamp the boss 22 on the inner cover 2. When the pressure disappears, the top of the outer cover 3 can automatically reset so that the outer groove 31 is separated from the boss 22. An exhaust groove 5 is provided at the junction of the outer wall of the outer cover 3 and the inner wall of the inner cover 2, so that the gas in the cup can pass through the waterproof and breathable membrane 4 and enter between the inner cover 2 and the outer cover 3, and be discharged through the exhaust groove 5 provided between the two.

[0023] When cleaning the lens, the gas in the cup enters between the inner cover 2 and the outer cover 3 through the air holes 21 and the air permeable membrane on the inner cover 2, and is discharged from the port of the cup cover along the exhaust groove 5. This design makes the air holes 21 and the air permeable membrane invisible in appearance, making the appearance more simple and beautiful. At the same time, when cleaning is completed and the cup cover needs to be opened, it is necessary to press the top of the outer cover 3 so that the outer groove 31 set on the inner top surface of the outer cover 3 is engaged with the boss 22 on the inner cover 2. Then, when the outer cover 3 is rotated, the inner cover 2 can be driven to rotate, thereby unscrewing the cup cover. When the pressure on the top of the outer cover 3 is released, the top of the outer cover 3 automatically resets, so that the boss 22 disengages from the outer groove 31, so that the inner cover 2 no longer rotates with the rotation of the outer cover 3. This structural design can prevent the cup cover from being accidentally opened, thereby improving the safety of use.

[0024] In addition, this embodiment also provides an inner groove 23 on the outer top surface of the inner cover 2, arranges the air vent 21 on the inner side of the inner groove 23, and fixes the waterproof breathable membrane 4 in the inner groove 23. This structural design facilitates the installation of the waterproof breathable membrane 4, and the inner groove 23 can limit the installed waterproof breathable membrane 4 to ensure the firmness of the installation of the waterproof breathable membrane 4.

[0025] Furthermore, in this embodiment, a plurality of sealing ribs 32 are provided on the inner top surface of the outer cover 3, which are evenly distributed around the outer periphery of the vent hole 21, and all the sealing ribs 32 are located on the inner side of the inner groove 23 and rest against the waterproof breathable membrane 4 to press the waterproof breathable membrane 4 and ensure the firmness of the installation of the waterproof breathable membrane 4.

[0026] In addition, this embodiment further provides an undercut structure 33 on the inner side of the port of the outer cover 3 so as to catch the edge of the port of the inner cover 2 and prevent the inner cover 2 from rotating into the outer cover 3 and detaching.

[0027] Furthermore, in this embodiment, a plurality of anti-slip protrusions 34 are evenly distributed around the outer wall of the outer cover 3 in the circumferential direction, so as to achieve the effects of anti-slip, easy screwing and labor-saving.

[0028] Furthermore, in this embodiment, the exhaust port of the exhaust groove 5 is set at the port of the outer cover 3 or the inner cover 2, so that the gas is discharged from the lower end of the cup cover, thereby further enhancing the aesthetic appearance.

[0029] The specific structural designs of the exhaust groove 5 in this embodiment include but are not limited to the following two types: the inner side wall of the outer cover 3 is provided with a groove with one end extending to its inner top surface and the other end penetrating its port edge to form the exhaust groove 5; or the inner side wall of the inner cover 2 is provided with a groove with one end extending to its outer top surface and the other end penetrating its port edge to form the exhaust groove 5.

[0030] The outer cover 3 in this embodiment is made of plastic, and its top is a thin-walled structure so that its top has deformation capability.

[0031] As can be seen from the above, the present invention configures the cup lid as a combination of an inner lid 2 and an outer lid 3. The structure of the outer lid 3 and the inner lid 2 is designed so that the outer lid 3 covers the air holes 21, the waterproof and breathable membrane 4, and the exhaust grooves 5 on its inner side. This design is simple and low-cost, and while ensuring waterproof and breathable effects, it also makes the appearance of the cleaning cup more beautiful. In addition, the outer lid 3 is rotatably mounted on the outside of the inner lid 2, allowing the outer lid 3 to rotate relative to the inner lid 2. When the inner lid 2 needs to be unscrewed, the top of the outer lid 3 is pressed so that the outer groove 31 on the outer lid 3 engages the boss 22 on the inner lid 2. The outer groove 31 cooperates with the boss 22, allowing the inner lid 2 to rotate as the outer lid 3 rotates, thereby achieving installation and opening of the cup lid. This structural design can prevent the cup lid from opening accidentally, improving user safety.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
