Abstract: A container cover device having an automatic vacuum function includes a container cover. The container cover is provided with an air extraction mechanism, a vacuum indication assembly, a first switch and a second switch. For the second switch, a control assembly is provided. The first switch and the second switch control the air extraction mechanism to open or close so as to extract the air in the container thorough. The vacuum indication member is to indicate whether the container is in a vacuum state or not for the user to check air leakage. The control assembly automatically controls connection or disconnection of the second switch, so that the air extraction mechanism is automatically started to extract the air in the container when there is air leakage. In this way, the inside of the container can be kept vacuum all the time, providing fresh-keeping and moisture-proof functions.
