This structure is usually made of precision metal or polymer materials, with a slender and precise nozzle shape to ensure that the flow and flow rate of the liquid can be accurately controlled during the filling process. In addition, the design of the filling nozzle must also consider its durability and sealing to ensure stable performance during long-term continuous work and effectively prevent liquid leakage. By optimizing the filling nozzle structure, the production efficiency and product quality of button batteries can be significantly improved.

The liquid injection channel structure forms a fluid channel for the flow of electrolyte, and the blocking structure has an open state and a blocking state. When the liquid injection machine injects liquid into the battery, the cavity part of the battery is inserted into the blocking structure, the blocking structure is in the open state, and the fluid channel is connected to the interior of the battery through the cavity part of the battery.

[0004] In the process of implementing this application, it was found that the technology had the following problems: the injection nozzle structure in the above patent document did not have a component designed to control the injection flow rate, and the injection amount could not be accurately controlled, resulting in unstable battery performance. At the same time, there was no structure to prevent the liquid from continuing to fall after the injection was completed, and the excess liquid would affect the product quality.

[0005] For this reason, a liquid injection nozzle structure of a liquid injection machine is proposed. Utility Model Content

Specifically, two groups of soft ring grooves 15 are arranged on the periphery of the pressing rod 10, with the soft ring 17 sandwiched therebetween, and the soft ring 17 is tightly in contact with the pressing rod 10 and the second limiting groove 16 to ensure the sealing and stability during the pressing process. This design effectively prevents liquid leakage and improves equipment performance. A group of buffer grooves 21 are arranged between the periphery of the second limiting groove 16 and the inner surface of the movable cover body 7, a group of springs 18 are vertically arranged inside the buffer groove 21, and the two side ends of the spring 18 are respectively fixed on the bottom outer surface of the pressing member 6 and the bottom outer surface of the buffer groove 21.

The two ends of the spring are respectively fixed on the bottom of the pressing member 6 and the bottom of the buffer groove 21, so as to provide a buffer effect during the pressing process, ensure smooth operation, and enhance structural stability.

[0027] Reference Figure 1-Figure 4The outer surfaces of the two groups of soft ring grooves 15 and the soft ring 17 are slidably connected to the inner surface of the second limiting groove 16. Specifically, the outer surfaces of the two groups of soft ring grooves 15 and the soft ring 17 are slidably connected to the inner surface of the second limiting groove 16, ensuring that the pressing rod 10 can move flexibly and smoothly during operation.
