ABSTRACT:
A vacuum pot capable of showing the vacuum status comprises a container and a cover body. The cover body comprises a seat, a top lid, an air-pumping unit, and an indicating unit. The top lid connects with the seat. A groove is installed on the top edge of the top lid. The air-pumping unit is installed between the seat and the top lid to draw out the air inside the container unidirectionally by the pressing and releasing of an air-pumping button. The indicating unit has a retractable pump. One end of the retractable pump connects with the seat. The retractable pump connects with the inside of the container. The other end of the retractable pump connects with a rack. The rack is meshed with a gear. The gear is pivotably installed on the seat. The gear fixedly joins a pointer installed in the groove of the top lid. A scale is installed on the groove. Thereby articles can be superposed on the cover body, the vacuum degree of the vacuum pot can be known exactly, and the user can operate using only one hand.
