The valve body is assembled in a liquid injection hole and includes a fixing portion and a sealing portion. The fixing portion is connected to an end cover. The sealing portion is connected to the fixing portion and configured to be in sealing engagement with the end cover. The valve core is at least partially fitted within the valve body and defines, with the valve body, a flow passage for communication with an external environment. The valve core is configured to drive, under an external force, the sealing portion to deform and separate from the end cover to form a flow port, the flow port being in communication with the flow passage. The end cover assembly, battery cell, battery, and electric apparatus provided in the present application have good waterproofing and high liquid injection efficiency.
