[0032] In this embodiment, the sealing member 104 is used to install the filling needle 1 on the vacuum inner sleeve 6 and plays a sealing role to prevent the entry of external air.

[0033] The vacuum inner sleeve 2 is arranged vertically, and is provided with a vacuum channel for inserting the needle tube 102 inside; the vacuum channel is divided into an upper vacuum channel and a lower vacuum channel which are interconnected; the diameter of the upper vacuum channel is larger than the diameter of the lower vacuum channel, and the diameter of the lower vacuum channel is larger than the outer diameter of the needle tube 102; the vacuum inner sleeve air outlet 201 is arranged at the side wall of the upper vacuum channel and is connected with the upper vacuum channel; a plurality of circular vacuum holes 202 are circumferentially arranged at the bottom of the lower vacuum channel; an inclined surface is circumferentially arranged at the bottom end of the vacuum inner sleeve 2, and the bottom is inclined toward the middle of the vacuum channel, and the inclined surface is used to facilitate the container 4 to be inserted upward into the groove.
