[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a portable low-temperature eye drop box, including a storage box 1. A connecting cavity 3 is opened in the middle of the storage box 1, and a storage cavity 2 is opened at both ends of the storage box 1. The proximal ends of the two storage cavities 2 are respectively connected to the left and right ends of the connecting cavity 3, and the distal ends of the two storage cavities 2 extend to the outside of the storage box 1. A piston assembly 4 is movably fitted inside each storage cavity 2. A sealing assembly 5 is provided in the middle of the outer surface of the storage box 1. The storage cavity 2 and the connecting cavity 3 are sealed with eye drops through the two piston assemblies 4. The middle of the connecting cavity 3 is connected to the sealing assembly 5. Ice cubes are placed inside the piston assembly 4. Due to the setting of the piston assembly 4, it is convenient for users to control the flow rate of eye drops, and it can effectively avoid the situation where the storage cavity 2 is filled with air and contaminates the eye drops. Moreover, the eye drops that are always filled between the two piston assemblies 4 can ensure that the flow rate of the squeezed eye drops remains stable and improve the comfort of dripping.

[0024] like Figure 3 As shown, the inner diameter of the connecting cavity 3 is smaller than that of the drug storage cavity 2, and the left and right ends of the connecting cavity 3 are respectively in contact with the opposing surfaces of the two piston assemblies 4.

[0025] like Figure 3 As shown, the piston assembly 4 includes a piston rod 41 that is movably sleeved inside the medicine storage chamber 2. Both piston assemblies 4 have a cold storage groove 42 on their opposite sides. The inside of the cold storage groove 42 is threaded and sealed with a heat insulation cover 43. A pull rod 44 is fixedly connected to the outside of the heat insulation cover 43. Due to the setting of the pull rod 44, the user can easily remove the piston assembly 4 to add eye drops or replace ice.

[0026] like Figure 3 As shown, the opposing surfaces of the two piston columns 41 are heat-transferring metal plates, and the heat-insulating cover 43 and the sides of the piston columns 41 are heat-insulating structures. Due to the setting of the heat-insulating cover 43, it is convenient to replace the ice in the storage box, so as to provide a low-temperature storage environment for the eye drops between the two piston assemblies 4 in the medicine storage chamber 2 and the connecting chamber 3 under the action of the heat transfer panel on the opposing surfaces of the two piston assemblies 4.

[0027] like Figures 3 to 5 As shown, the sealing assembly 5 includes a sealing groove 51 located in the middle of the outer surface of the medicine storage box 1. The sealing groove 51 is located on the outside of the connecting cavity 3. A sealing ring 52 is sealed inside the sealing groove 51. A medicine outlet hole 53 is provided in the middle of the sealing ring 52. The lower end of the medicine outlet hole 53 penetrates the medicine storage box 1 and extends into the interior of the connecting cavity 3. Due to the setting of the sealing groove 51, the installation of the sealing ring 52 is facilitated. With the cooperation of the anti-slip groove 54, the user can easily and quickly control the rotation of the sealing ring 52, thereby realizing the passage of the medicine outlet hole 53.

[0028] like Figures 3 to 5 As shown, the outer diameter of the sealing ring 52 is the same as that of the medicine storage box 1, and the outer surface of the sealing ring 52 is provided with anti-slip grooves 54.

[0029] like Figures 3 to 5 As shown, the medicine storage box 1 has a limiting groove 55 located at both ends of the sealing groove 51. A limiting block 56 is slidably engaged inside the limiting groove 55. The limiting block 56 passes through the limiting groove 55 and extends into the interior of the sealing groove 51 and is fixedly connected to the left and right sides of the sealing ring 52. When the two ends of the medicine outlet 53 are interconnected, the limiting block 56 is located at one end of the limiting groove 55. Due to the setting of the limiting groove 55 and the limiting block 56, the stability of the sealing ring 52 after repeated rotation can be improved with the cooperation of the sealing groove 51, thereby ensuring the sealing of both ends of the medicine outlet 53. Moreover, it can facilitate the user to quickly align the two ends of the medicine outlet 53 and realize the rapid connection of the medicine outlet 53.

[0030] Working principle and usage process of this utility model:

[0031] Unscrew the insulation cover 43 by pulling rod 44, place ice cubes inside the cold storage tank 42, tighten the insulation cover 43, insert a piston assembly 4 into one of the drug storage chambers 2, inject an appropriate amount of eye drops into the other drug storage chamber 2, and then insert the other piston assembly 4 into the upper and lower drug storage chambers 2, ensuring that the space between the two piston assemblies 4 is completely filled with eye drops and no air remains.

[0032] When using the product, rotating the sealing ring 52 via the anti-slip groove 54 will allow the medicine outlet 53 in the sealing ring 52 to communicate with the medicine outlet 53 in the medicine storage box 1 and medicine storage cavity 2 under the restriction of the sealing groove 51, the limiting groove 55, and the limiting block 56. At this time, pressing the two piston assemblies 4 will bring them closer together and squeeze out the eye drops, allowing them to flow out from the medicine outlet 53. After use, rotating the sealing ring 52 in the opposite direction will disconnect the medicine outlet 53.

[0033] During the carrying period, the ice in the cold storage tank 42 can provide a low-temperature storage environment for the eye drops through the heat transfer panels on the opposing surfaces of the two piston assemblies 4.
