The pump body 5 has an air inlet end 11 and an exhaust end. The air inlet end 11 is connected to the air extraction port 8 through a pipeline, and the exhaust end can communicate with the tube body 3. When the pump body 5 is evacuated, the air in the bag body 1 is pumped into the tube body 3 and exhausted through the exhaust port 10 of the tube body 3. At the same time, the air pressure switch 6 is connected to the air pressure detection port 9. According to the set vacuum degree, when the vacuum degree in the bag body 1 reaches the set value, the air pressure switch 6 control circuit is disconnected, and the pump body 5 stops working.

[0031] In specific use, the vacuum device 2 is installed at the opening position of the bag body 1, and the switch button of the vacuum device 2 is pressed to drive the pump body 5 to operate. The pump body 5 pumps the air in the bag body 1 to the tube body 3, and discharges it through the exhaust port 10 of the tube body 3.

At the same time, the vacuum device 2 and the bag body 1 are detachably connected, so that the advantage of the bag body 1 can be reused; an air pressure switch 6 is arranged in the vacuum device 2 to control the vacuum degree in the bag body 1. When the vacuum degree reaches the preset vacuum degree, the pump body 5 automatically cuts off the power to complete the vacuum process, which is more convenient to use.

[0033] Specifically, a conduit is provided at the air extraction port 8, and the conduit extends into the bag body 1. To facilitate the extraction of air from the bag body 1, a conduit can be added to the air extraction port 8, and the conduit extends into the bag body 1, so as to facilitate the extraction of air from the bag body 1.

[0034] As shown in the figure, the bag body 1 is provided with a shell 13 for accommodating the air extraction device 2 at the opening position, the shell 13 is a hollow tube, and the air extraction device 2 is accommodated in the shell 13.

An external thread 14 is set at the upper end of the shell 13, and an internal thread 15 is set on the end cover 19 of the vacuum device 2. When the vacuum device 2 is installed, the tube body 3 is placed in the shell 13, and the end cover 19 of the vacuum device 2 is threadedly connected and fixed to the shell 13, thereby realizing the installation and disassembly of the vacuum device 2.

[0036] Specifically, it includes a charging port 16 , which is exposed on the end cover 19 . The charging port 16 is arranged on the circuit board 7 , and is used to charge the battery 4 .

[0037] Furthermore, the bag body 1 is provided with a handle 17. The provided handle 17 is used to take the bag body 1.

[0038] Furthermore, a T-shaped rubber plug 18 is installed at the air inlet end 11 of the pump body 5 . The T-shaped rubber plug 18 is hollow and used to seal the air inlet end 11 of the pump body 5 . The air outlet end 12 of the pump body 5 is higher than the air inlet of the T-shaped rubber plug 18 .

[0039] The T-shaped rubber plug 18 is convenient for sealing the pipeline and the air inlet end 11 of the pump body 5 to improve the air extraction effect. At the same time, the air outlet end 12 of the pump body 5 is higher than the air inlet of the T-shaped rubber plug 18, forming a height difference, which can help the air outlet end 12 of the pump body 5 to exhaust.
