Vacuum heat preservation container water dispenser capable of being automatically powered off

The utility model discloses a vacuum heat preservation container water dispenser capable of being automatically powered off. The vacuum heat preservation container water dispenser is based on the control technology of a single-chip microcomputer (4). A vacuum heat preservation container (1) has the good heat preservation performance, cooled or heated water can be slowly heated or cooled in the vacuum heat preservation container (1) for a long time, the work time of a compressor or a heater is effectively reduced, on this basis, when the single-chip microcomputer (4) controls refrigeration or heating, the analog quantity output by a water temperature sensor (3) is uninterruptedly sampled, whether a person drinks water or not can be judged, when the continuous time without people drinking the water is accumulated to reach the preset value, one I/O terminal of the single-chip microcomputer (4) sends out a power-off signal (6), the water dispenser is controlled to be in the power-off state, and the electricity sa
