In a negative pressure sealing structure and a negative pressure sealing method, the cavity is under vacuum negative pressure during use and ambient air pressure during non-use, and the sealing body that cooperates with the cavity also changes with the pressure state in the cavity. Changes, and corresponding deformation occurs, so that the fit tightness between the sealing body and the cavity changes. When the cavity is in a negative pressure state, the sealing body is deformed so that the sealing pressure between the sealing surface of the cavity and the cavity is increased, and the airtightness is improved; when the cavity is in an ambient air pressure state, the sealing body returns to the initial state, and the sealing body and the cavity The sealing pressure between the sealing surfaces is reduced, and it is convenient for the user to separate the sealing body and the cavity. The vacuum food processor, vacuum fresh-keeping tank and vacuum press adopting the negative pressure sealing structure of the present invention, while ensuring the airtightness of the working state, improve the user's convenience of putting in and taking out food, and improve experience.
