Document Type and Number:
WIPO Patent Application WO/2022/267227
Kind Code:
A1
Abstract:
An axial water intake type dual-path single-control valve core, comprising a valve casing (10) and a valve seat (20), wherein the valve seat (20) is provided with a water intake path and a water output path, and the valve casing (10) is internally provided with a valve stem (11), a movable plate (12) and a static plate (13). The static plate (13) is provided with a water inlet and a water outlet. The water intake path extends towards the end of the valve seat (20) that faces away from the valve casing (10), and the axis of the water intake path is parallel to the axis of the valve casing (10). The water output path (21) is internally provided with a tapered spray pipe (22), wherein a small-diameter end of the tapered spray pipe (22) faces the end of the water output path (21) away from the water outlet (131), and a large-diameter end of the tapered spray pipe (22) is in communication with the water outlet (131); the cross-sectional flow of the small-diameter end of the tapered spray pipe (22) is less than the cross-sectional flows of the water output path (21), the water outlet (131) and the large-diameter end of the tapered spray pipe (22); and the axis of the small-diameter end of the tapered spray pipe (22) is concentric with the axis of the end of the water output path (21) away from the water outlet (131). The valve seat (20) is further provided with a secondary water output path (23), the secondary water output path (23) being in communication with the inner wall of the water output path (21) that is located between the large-diameter end and the small-diameter end of the tapered spray pipe (22).
