Specifically, when liquid food needs to be extracted, the negative pressure dual-purpose pump operates in a mode of outputting negative pressure, the liquid food overcomes the elastic action of the elastic member 330 to generate a gap between the sealing member 500 and the first liquid inlet 110, and the liquid food to be extracted is pumped into the liquid storage cavity through the liquid inlet pipe 121, the liquid inlet cavity, the first liquid inlet 110 and the second liquid inlet 230; the ray generating part 700 can be opened before and after the liquid food is extracted so as to disinfect the liquid in the liquid storage cavity of the wing of the liquid storage body 210. When liquid food is discharged from the liquid storage cavity, the stirring assembly 600 can be used for stirring the liquid in the liquid storage cavity, the negative pressure dual-purpose pump is operated in a mode of outputting positive pressure, and meanwhile, the control rod 310 is pulled manually by an operator, so that the control rod 310 drives the sealing piece 500 to be away from the first liquid inlet 110, and the liquid food is discharged from the liquid storage cavity through the second liquid inlet 230, the first liquid inlet 110, the liquid inlet cavity and the liquid discharge pipe in sequence. The extraction method of liquid food that this embodiment provided easy operation, degree of automation is high, and labour saving and time saving accords with the leakproofness detection requirement to food.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
