[0028] Among them, the placement groove 12 is a cylindrical structure, and the placement groove 12 is located at the center of the equipment base 1. The thickness of the placement groove 12 is less than the thickness of the equipment base 1. The placement groove 12 is adapted to the bottom of the thermos bottle, so as to facilitate the placement of the thermos bottle. A display screen and control buttons are arranged on the outside of the control panel 14, and the control panel 14 is electrically connected to the electric telescopic rod 13, the pressure sensor 15, the pressure sensor 9, the air pump 10, the electric telescopic rod 2 132 and the pressure sensor 2 133. A control circuit board and a battery are arranged inside the control box 15. The control panel 14 is electrically connected to the control circuit board, which is conducive to controlling the electric telescopic rod 13 to adjust up and down, driving the connecting groove 7 to seal the top of the thermos bottle. The number of electric telescopic rods 3 is two groups and they are symmetrically distributed. The output end of the electric telescopic rod 3 is fixedly connected to the detection end of the pressure sensor 5. The pressure sensor 5 is connected to the sealing plate 6 by bolts, which is conducive to driving the sealing plate 6 to rise and fall.

[0029] In addition, the connecting groove 7 is located in the middle of the sealing plate 6, and the sealing gasket 8 is a rubber ring structure, which is convenient for connecting and sealing the mouth of the thermos bottle.
