The first interface is communicated with the ventilation port of the connecting pipe 111 through a pipeline, the second interface is communicated with the pressure relief port of the pressure relief valve through a pipeline, and the third interface is communicated with the air suction port of the vacuum pump through a pipeline.

[0093] When the first channel 211A and the second channel 411 are docked to form a connection channel, the vacuum pump works to evacuate the storage cavity a through the connecting pipe 111, the air pressure in the storage cavity a decreases, and the liquid in the liquid storage cavity b flows into the storage cavity a through the connection channel; when the liquid and the material are mixed completely, the pressure relief valve works to relieve the pressure of the storage cavity a through the connecting pipe 111, the air pressure in the storage cavity a increases, and the liquid in the storage cavity a flows back into the liquid storage cavity b through the connection channel.

[0094] Certainly, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations and substitutions are all included in the scope defined by the claims of this application.
