[0002] With the wide use of liquid cooling system in container integrated system, the liquid injection operation of the system becomes more and more important. In the prior art, the traditional liquid injection device has many problems. On the one hand, the electric control part and the pump body of many liquid injection devices are separated, which makes the device need complex wiring and assembly during installation and use, consumes a lot of manpower and time cost, and due to the separation structure, the overall device has a large volume and occupies a lot of space, which is not conducive to flexible deployment.
