Document Type and Number:
WIPO Patent Application WO/2017/113449
Kind Code:
A1
Abstract:
Provided are a straw capable of automatically switching a drinking channel and a water cup. The straw comprises a straw body (1), a piston sleeve (2) and a hollow piston (3), wherein the piston sleeve (2) is arranged at one end of the straw body (1) and a radial water inlet hole (21) is formed in a wall of the piston sleeve; the piston (3) is sheathed inside the piston sleeve (2) and can slide relative to the sleeve; the piston (3), the piston sleeve (2) and the straw body (1) are in communication in the axial direction; when the straw body (1) is vertically placed, the piston (3) is located at the bottom end of the piston sleeve (2) so as to block the water inlet hole (21); and when the straw body (1) is reversed, the piston (3) is located at the top of the piston sleeve (2) so as to open the water inlet hole (21). The automatic switching of the drinking channel can be achieved such that regardless of whether the water cup is vertically placed or reversed, a user can normally drink water and the whole process does not require any manual operation; and the straw is convenient and rapid to use, simple in structure, easy to wash and low in cost.
