Centrifugal battery liquid injection mechanism and liquid injection method thereof

A centrifugal battery liquid injection mechanism, comprising a liquid injection device, a driving device, and a supporting device, wherein,

• the liquid injection device comprises a main body and a plurality of supporting columns extending along a liquid injection direction and arranged around the main body;
• the main body has two ends opposite to each other, wherein one of the two ends is arranged with a liquid outlet head capable of being opened and closed and a liquid injection port capable of being opened and closed;
• the liquid injection port is used for injecting a wetting liquid into the liquid injection device;
• and the liquid injection device is connected with a to-be-wetted device through the liquid outlet head, so as to inject the wetting liquid into the to-be-wetted device;
• a piston mechanism is arranged inside the main body;
• the other of the two ends is arranged with a mechanical valve;
• and the mechanical valve is connected with an external air pump, so as to drive the piston mechanism to slide in the liquid injection device based on air blowing and suction of the air pump;
• the piston mechanism comprises a piston and a driving rod;
• an edge of the piston clings to an inner wall of the liquid injection device, and the driving rod is connected with the piston, so as to drive the piston to slide along the inner wall of the liquid injection device;
• the piston is capable of moving towards one end of the liquid outlet head, and therefore injects the wetting liquid into the liquid into the to-be-wetted device;
• the piston is capable of moving towards one end far away from the liquid outlet head, so as to pump out gas in the to-be-wetted device;
• the driving device is connected with the to-be-wetted device for driving the to-be-wetted device to move;
• and
• the liquid injection device and the to-be-wetted device are both connected with the supporting device, and the driving device is connected with the to-be-wetted device by being connected with the supporting device;
• the supporting device comprises a bracket, and the liquid injection device is detachably connected with the bracket;
• in condition of the liquid injection device being detached with the bracket, the plurality of supporting columns pass through the bracket.
