Title:
NOVEL VALVE USED FOR VENTILATION OF BOTTOM OF FLUID SUPPLY CUP
Document Type and Number:
WIPO Patent Application WO/2023/124715
Kind Code:
A1
Abstract:
A novel valve used for ventilation of the bottom of a fluid supply cup, said valve comprising a base (2) capable of being matched with a valve housing (1) at the bottom of the fluid supply cup, a blocking member (3) being hinged on the base (2). A tenon pin (5) used for sealing a vent hole (4) at the bottom of the fluid supply cup is arranged on the blocking member (3), a locking buckle being arranged on the outer wall of the base (2). The locking buckle is matched with the inner wall of the valve housing (1), at least one fixing ring being arranged on the inner wall of the valve housing (1). By means of the match between an inner wall (8) of a locking position (7) and a side wall (9) of the blocking member (3), the locking position (7) deforms when just in contact with the blocking member (3). When all of the blocking member (3) is clamped, the inner wall (8) of the locking position (7) recovers the original form, so the blocking member (3) can be clamped into the locking position (7) more smoothly, meaning that the finished base essentially does not undergo any deformation, and the stability of the performance of the finished product is greatly improved.
