Abstract: The present disclosure relates to the technical field of small household appliances and discloses a separable evacuation device. The separable evacuation device includes an evacuation module. The evacuation module includes a base, which is connected to an opening of a to-be-evacuated container; a vacuum pump, which is disposed on the base and configured to vacuum the to-be-evacuated container; a power supply assembly, which is connected to the vacuum pump and configured to supply power to the vacuum pump; and a control assembly, which is connected to the power supply assembly and the vacuum pump and includes a vacuum pressure switch. The vacuum pressure switch is configured to detect an air pressure value in the to-be-evacuated container and control the power supply assembly to perform one of supplying power to the vacuum pump or powering off the vacuum pump.
