Document Type and Number:
WIPO Patent Application WO/2021/139123
Kind Code:
A1
Abstract:
A liquid drawing device and a container having same. The liquid drawing device comprises: a piston (1) that can move up and down; a fixed part (2) provided with a suction chamber (20) allowing the piston (1) to move up and down; a liquid suction means that can move up and down to drive the piston (1) to move up and down in the liquid suction chamber (20); a rotatable sleeve (3) that can rotate back and forth to drive the liquid suction means to move up and down; a housing (7) rotatably fitted to the rotatable sleeve (3). When the housing (7) is rotated, the rotatable sleeve (3) is rotated under the drive of the housing (7) to drive the liquid suction means to move up and down, so as to drive the piston (1) to move up and down along the liquid suction chamber (20) to draw the liquid. The provision of the present structure enables the piston (1) to move up and down in the liquid suction chamber (20) under the drive of the liquid suction means so as to achieve drawing of the liquid, such that the entire liquid drawing device can be made of the same material, such as plastic, thus achieving the purpose of convenient recovery, high efficiency, and low cost.
