[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0022] Reference Figures 1-5 A contact lens storage device, comprising a first base 1 and a second base 2, the first base 1 is connected with the second base 2, a nursing liquid packaging bottle 3 is arranged on the first base 1, an external thread joint 4 is arranged on the second base 2, a screw cap 5 is threadedly connected on the external thread joint 4, a storage cavity 6 is formed on the second base 2, the storage cavity 6 corresponds to the position of the external thread joint 4, a liquid supplement pipe hole 7 is formed in the first base 1 and the second base 2, the liquid supplement pipe hole 7 is communicated with the nursing liquid packaging bottle 3 and the storage cavity 6 respectively, a connecting rod 8 is rotatably connected on the inner wall of the storage cavity 6, a first floating ball 9 is connected on the bottom end of the connecting rod 8 close to the center of the storage cavity 6, a tapered plug 10 is connected on the other end of the connecting rod 8, and the tapered plug 10 is sealingly connected at the communication between the liquid supplement pipe hole 7 and the storage cavity 6.
[0023] When the water level height of the nursing liquid in the storage cavity 6 is reduced, the first floating ball 9 is sagged under the action of gravity, thereby driving the connecting rod 8 to rotate downward in the storage cavity 6, and further driving the tapered plug 10 to rotate and open the blocked liquid supplement pipe hole 7, so that the nursing liquid in the nursing liquid packaging bottle 3 is automatically supplemented into the storage cavity 6 along the liquid supplement pipe hole 7, and the storage cavity 6 always has sufficient nursing liquid, which is helpful for the storage of the contact lens and is convenient to use. When the water level rises, the first floating ball 9 rises, the connecting rod 8 drives the tapered plug 10 to rotate, thereby blocking the liquid supplement pipe hole 7, and further realizing the automatic stop in the nursing liquid supplement process, which avoids waste and ensures that the storage cavity 6 always has nursing liquid with a uniform capacity.
[0024] Specifically, in the embodiment, an internal thread joint 11 is arranged on the first base 1, and a threaded mouth of the nursing liquid packaging bottle 3 is threadedly connected in the internal thread joint 11, so that the nursing liquid packaging bottle 3 is convenient to replace.
[0025] Specifically, in the embodiment, the inner wall of the storage cavity 6 is provided with a hinge 12, and one end of the connecting rod 8 close to the conical plug 10 is rotatably connected in the hinge 12, so as to ensure the integrity of the connection between the connecting rod 8 and the storage cavity 6.
[0026] Specifically, in the embodiment, the connecting rod 8 is a hollow pipe, so as to reduce the weight of the connecting rod 8 and improve the overall buoyancy effect.
[0027] Specifically, in the embodiment, the storage cavity 6 is provided with a separation net 13, and the separation net 13 is arranged in a circular arc shape, with the inner circular arc direction close to the first floating ball 9 side. The circular arc-shaped separation net 13 provides sufficient space for the rotation of the first floating ball 9, and isolates the contact lens from the first floating ball 9, so as to prevent the contact lens from being scratched.
