WIPO Patent Application WO/2021/169140
Kind Code:
A1
Abstract:
Disclosed is a water path control device. The water path control device comprises a mounting portion (1), a valve shaft (2) connected to the mounting portion (1) in a sliding manner and an elastic body (3). The mounting portion (1) is provided with a first water path (11) and a second water path (12); a blocking portion (21) and a first sealing member (23) are fixedly arranged on the valve shaft (2); the blocking portion (21) is arranged in the second water path (12), and the blocking portion (21) is driven to slide by means of the sliding of the valve shaft (2) so as to control whether the blocking portion (21) blocks the second water path (12); the elastic body (3) is arranged between the valve shaft (2) and the mounting portion (1) and can generate an elastic force, the first sealing member (23) can generate a water acting force under the hydraulic action of the first water path (11), the water acting force is larger than the elastic force, the directions of the water acting force and the elastic force are the opposite of each other, and the water acting force can act on the valve shaft (2) to drive the blocking portion (21) to block the second water path (12). The device has the following advantage: a switch mechanism does not need to be arranged at the rear end of a water path.
