INTELLIGENT VACUUM PRESERVATION BOXES AND CONTROL METHOD THEREOF

摘要

The present invention relates to a smart vacuum freshly maintained lunch box and a control method thereof, which includes a lunch box body, a lunch box cover, an air suction and discharge structure, and a control module, and an air suction and discharge structure and a control module are installed in the lunch box cover , The lunch box cover and the lunch box body are detachably connected, and the control module controls the air intake and exhaust structure. The control method of the smart vacuum freshly maintained lunchbox includes detecting a power amount of the battery BT1, detecting whether the lunch box is in a horizontal state, detecting whether the lunch box cover is rotating, and detecting whether the lunch box cover is covered in the lunch box body. The present invention has the advantage that the freshness retention time is long and the freshness retention effect is excellent because the air is pumped out through the air suction pump and the air is discharged from the lunch box and the air leakage speed is greatly reduced to increase the degree of vacuum. The present invention further realizes smartization and thus has a long service life.;
