The mounting tube 31 is fixedly connected to the housing 1. The housing 1 is penetrated with a through hole 12 connected to the mounting tube 31. The through hole 12 is connected to the suction end of the vacuum pump 101. The sealing sleeve 32 is sleeved with the mounting tube 31, and the sealing sleeve 32 covers the inner wall of the mounting tube 31. When the sealer seals a sealed container with a small-caliber interface such as a vacuum lunch box or a vacuum red wine bottle, the user can seal the elastic interface member 3 with the interface of the sealed container to vacuumize the inner cavity of the sealed container. The housing 1 is penetrated with an exhaust hole 13, which is connected to the exhaust end of the vacuum pump 101.

[0026] The controller 103 is composed of a circuit board and a button. The controller 103 has a timing module and an air pressure sensing module. By pressing the button, the vacuum pump 101 starts to work and perform a vacuum operation, the timing module starts timing, and the air pressure sensing module senses the negative air pressure generated by the vacuum pump 101 until the display screen 102 times 1S to 50S or the air pressure is greater than 50Kpa, the vacuum pump 101 stops working, and then the solenoid valve of the vacuum pump 101 opens for 5S to perform a vacuum breaking operation, so that the user can open the sealer and take it out of the sealed container.
