Title:
FLUSHING PRESSURE LOSS PREVENTING ASSEMBLY AND WATER TANK
Document Type and Number:
WIPO Patent Application WO/2020/082193
Kind Code:
A1
Abstract:
A flushing pressure loss preventing assembly (100), comprising: a fixed cylinder (10), a water bag (20) connected to the fixed cylinder (10), a movable core (30) penetrating the water bag (20), a sealing member (40) connected to the movable core (30), and an elastic member (50) connected between the movable core (30) and the water bag (20). The fixed cylinder (10) is used for mounting at an overflow port (401) of an overflow pipe (400) of a water tank (1000); the fixed cylinder (10) is provided with an overflow hole (11)used for communicating with the overflow pipe (400); the water bag (20) comprises: a bag body (21) and an elastic partition block (22); the sealing member (40) is used for plugging the overflow hole (11); the elastic member (50) is used for providing a driving force for resetting the movable core (30). At that same time, also provided is the water tank (1000) comprising the flush pressure stop assembly (100). During flushing, water released from the water tank (1000) is used as a driving force to push the movable core (30) to move, so as to drive the sealing member (40) to seal the overflow hole (11), thereby sealing the overflow port (401) of the overflow pipe (400). Therefore, water in a flushing pipe (300) of the water tank (1000) cannot overflow to the outside from the overflow port (401) of the overflow pipe (400), thereby reducing the pressure loss during flushing and improving a cleaning effect.
