Separable evacuation device

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.

What is claimed is: 
     
         1 . A separable evacuation device, comprising an evacuation module, wherein the evacuation module comprises:
 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 comprises a vacuum pressure switch, wherein 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.   
     
     
         2 . The separable evacuation device according to  claim 1 , further comprising an interaction assembly connected to the control assembly, wherein the interaction assembly is configured to display a status of the vacuum pressure switch and input a signal for controlling the vacuum pressure switch. 
     
     
         3 . The separable evacuation device according to  claim 2 , wherein the control assembly further comprises a first electromagnetic wave signal transceiver, a second electromagnetic wave signal transceiver is disposed on the interaction assembly, and the first electromagnetic wave signal transceiver and the second electromagnetic wave signal transceiver mutually transmit electromagnetic wave signals. 
     
     
         4 . The separable evacuation device according to  claim 1 , wherein an air port is disposed on the base, a solenoid valve is disposed at the air port, and the solenoid valve is configured to be opened to communicate the to-be-evacuated container with outside atmosphere or be closed to isolate the to-be-evacuated container from the outside atmosphere. 
     
     
         5 . The separable evacuation device according to  claim 1 , wherein the evacuation module further comprises a sealing ring, which is disposed at a connection position of the base and the to-be-evacuated container. 
     
     
         6 . The separable evacuation device according to  claim 1 , wherein a connection assembly is configured to be further disposed between the evacuation module and the to-be-evacuated container, one end of the connection assembly is detachably connected to the base, and the other end of the connection assembly is detachably connected to the to-be-evacuated container. 
     
     
         7 . The separable evacuation device according to  claim 1 , wherein the power supply assembly comprises a rechargeable battery. 
     
     
         8 . The separable evacuation device according to  claim 7 , wherein the power supply assembly further comprises a wireless charging coil, which is connected to the rechargeable battery and is configured to charge the rechargeable battery. 
     
     
         9 . The separable evacuation device according to  claim 1 , wherein the control assembly further comprises a power switch, which is electrically connected to the power supply assembly and is configured to control an operation of the power supply assembly or stop the operation of the power supply assembly.
