Multi-purpose vacuum machine

A multi-purpose vacuum machine, comprising:

• a body comprising at least two end faces, each of the at least two end faces defining a vacuum chamber;
• the vacuum chamber comprising a chamber base and a sealing ring, and the chamber base defining at least one air suction hole;
• an air extraction assembly comprising a vacuum pump and a multi-way valve, the multi-way valve comprising a first port and at least one second port, a number of the at least one second port is equal to a number of the at least one air suction hole, and the first port being selectively in communication with one of the at least one second port to form different connection states;
• the first port being in communication with the vacuum pump, and each of the at least one second port being in communication with a corresponding one of the at least one air suction hole;
• a direction sensing switch configured to obtain a directional change of the body;
• and
• a main control board;
• the vacuum pump, the multi-way valve and the direction sensing switch being electrically connected to the main control board, and the main control board configured to control the connection state of the multi-way valve based on a direction obtained by the direction sensing switch;
• wherein the vacuum chamber is configured to accommodate a bottle mouth of a container and seal the bottle mouth, and the at least two of the vacuum chambers comprises at least two different accommodation sizes to adapt to bottle mouths of different sizes.
