The liquid injection mechanism 13 includes a movable member 131 and an elastic member 132, wherein one end of the elastic member 132 is respectively abutted against the cover plate 11 or the liquid storage bin 12, and the other end is abutted against the movable member 131, so that the movable member 131 seals the liquid outlet 104 under the elastic force of the elastic member 132, and the movable member 131 overcomes the elastic force of the elastic member 132 to open the liquid outlet 104 when receiving the external force.

A cover plate assembly according to claim 3, wherein the movable member is further configured to open the liquid inlet when the external force is applied, and the cover plate includes an inclined guide surface disposed near one side of the liquid inlet, so that after the external force is removed, the movable member returns to close the liquid inlet and the liquid outlet along the inclined guide surface under the action of the elastic force of the elastic member.
8. The closure assembly of claim 1, wherein,
The liquid injection mechanism is provided with a liquid injection channel, the cover plate is used for sealing the liquid injection channel when the liquid injection mechanism is not acted by external force, and the liquid injection channel is communicated with the liquid storage cavity when the liquid injection mechanism is acted by the external force; or (b)
The liquid injection mechanism comprises an inclined drainage surface which is close to one side of the liquid injection port, and the liquid injection mechanism is used for forming a liquid injection gap communicated with the liquid storage cavity between the inclined drainage surface and the cover plate under the action of external force.
9. A shell, characterized in that the shell comprises a shell body and the cover plate assembly according to any one of claims 1-8, wherein the shell body is provided with a containing space for containing a core bag and a common electrolyte, and the cover plate is covered in the containing space and the liquid outlet is communicated with the containing space.
10. A battery, comprising a core pack and the housing of claim 9, wherein the core pack is disposed in the accommodating space.
