Title:
STRUCTURE OF TOILET LID DAMPER FOR MAINTAINING CONSTANT PRESSURE
Document Type and Number:
WIPO Patent Application WO/2018/165838
Kind Code:
A1
Abstract:
Provided is a structure of a toilet lid damper for maintaining constant pressure, comprising a sealing cover (1), a sealing ring (2), a valve core (3), a rotating ring (4), an oil cavity housing (5), and a blade (6), wherein the sealing cover (1) is sheathed in the oil cavity housing (5) and an outer wall of the sealing cover (1) is welded to an inner wall of the oil cavity housing (5); the sealing ring (2) is sheathed in a rubber ring groove (31) of the valve core (3) and is located between the sealing cover (1) and the valve core (3); and a central hole of the sealing cover (1) is sheathed at an upper end of the valve core (3); a cylindrical lug boss (33) of a lower end of the valve core (3) is sheathed in a cylindrical groove (52) of an inner bottom face of the oil cavity housing (5). Since the rotating ring (4) is additionally provided, a triangular groove (41) on the rotating ring (4) cooperates with a triangular protrusion (322) at the middle part of the valve core (3), and under the action of oil pressure, the rotating ring (4) climbs upwards or downwards along a slope of the triangular protrusion (322), ensuring a gap between a lower surface (323) of an annular protruding ring (32) of the valve core (3) and a side face (62) of the blade (6) is always 0mm, ensuring damping oil only passes through a small oiling slot (61) under a damping action, and ensuring the size of the oil-flow area remains unchanged throughout, thereby ensuring the stability of the slow descending time of a toilet lid plate.
