A liquid drawing device includes a main body assembly, a drawing pump mounted inside the main body assembly; an adjustable air intake is mounted outside the air intake hole of the connecting seat of the main body assembly, and the first liquid delivery pipe of the connecting seat is mounted with a drawing straw. With the drawing pump drawing liquid inside a container, the procedure of liquid drawing may not be restricted by whether an airtight condition of an opening of the container is well maintained, and an opened degree of the air intake hole of the connecting seat can be adjusted by the adjustable air intake. Besides, because the drawing straw is a telescopic pipe assembly with a plurality of sections, the liquid drawing device can be conveniently carried around after the drawing straw is retracted and shortened. |
