[0035] See also Figures 1 to 8 The utility model is a capacitor vacuum automatic liquid injection device, comprising a cup body 1, a connecting piece 2, a first tube body 3, an auxiliary vacuum pumping component 4, a liquid injection pressurizing component 5 and a second tube body 6;

[0036] The connecting member 2 is connected to the cup body 1 to form a cavity, and the connecting member 2 is provided with a flow channel 201, and the two ends of the flow channel 201 are connected to the cavity and an external container respectively;

[0037] The auxiliary vacuum pumping component 4 is disposed on the cup body 1 and away from the connecting piece 2. The auxiliary vacuum pumping component 4 is used to block the flow channel 201 or stay away from the flow channel 201.

[0038] The first tube body 3 is communicated with the flow channel 201 , the liquid injection and pressurizing assembly 5 is disposed on the cup body 1 and communicated with the cavity, and the second tube body 6 is disposed on the cup body 1 and communicated with the cavity.

[0039] Specifically, in this embodiment, the cup body 1 includes a cylinder and a cover plate. The cylinder is in a hollow cylindrical shape. The cover plate is fixedly connected to the cylinder and sealed with a sealing ring. The connecting piece 2 is fixedly connected to the cylinder and sealed with a sealing ring.

The upper through hole 101 is arranged along the side wall of the cylinder. The second tube body 6 is connected to the cavity through the upper through hole 101. A lower through hole 203 and a flow channel 201 are processed on the connecting piece 2. The lower through hole 203 is connected to the flow channel 201. The flow channel 201 is arranged along the central axis of the connecting piece 2. The flow channel 201 connects the cavity with the external container 100. The first tube body 3 is connected to the flow channel 201 through the lower through hole 203. The working principle is as follows: first, the external container 100 is connected to the connecting piece 2, the flow channel 201 is connected with the external container 100, the auxiliary vacuum pumping component 4 seals the end of the flow channel 201 close to the cavity, and then the external container 100 is vacuumed through the first tube body 3. When the air pressure in the container 100 reaches the preset value, the first tube body 3 is closed, the auxiliary vacuum pumping component 4 is away from the flow channel 201, and the external electrolyte is injected into the cavity through the liquid injection and pressurizing component 5, and then enters the external container 100 through the flow channel 201. Then the auxiliary vacuum pumping component 4 is further away from the flow channel 201, and the second tube body 6 is started to vacuum the cavity. The air pressure in the container 100 is further reduced, the second tube body 6 is closed, and the external electrolyte is injected into the cavity through the liquid injection and pressurizing component 5, and then enters the external container 100 through the flow channel 201. The above actions are repeated, that is, vacuuming through the second tube body 6 for multiple times, and liquid injection through the liquid injection and pressurizing component 5 for multiple times, so as to achieve the purpose of filling the container 100 with electrolyte.

[0040] By setting up a capacitor vacuum automatic liquid injection device composed of a cup body 1, a connecting piece 2, a first tube body 3, an auxiliary vacuum pumping component 4, a liquid injection pressurizing component 5 and a second tube body 6, under the action of the first tube body 3, the auxiliary vacuum pumping component 4, the liquid injection pressurizing component 5 and the second tube body 6, the purpose of multiple vacuum pumping and multiple liquid injections is achieved, and the external container 100 is filled with electrolyte to meet the production requirements.
