WIPO Patent Application WO/2022/227155
Kind Code:
A1
Abstract:
The present utility model provides an anti-siphon assembly, a drainage device, and a toilet device. The anti-siphon assembly comprises: a water inlet pipe; and a water outlet pipe, the water of the water inlet pipe flowing into the water outlet pipe under the action of an inlet water pressure. When the flowing of the water of the water inlet pipe is stopped, an air break is formed between a water outlet end of the water inlet pipe and a water inlet end of the water outlet pipe; when the water of the water inlet pipe flows in, a movable member moves under the action of a driving force and at least partially closes the air break to prevent or reduce the flowing of the water of the water inlet pipe out of the air break; or when the water of the water inlet pipe flows in, the water outlet end of the water inlet pipe and the water inlet end of the water outlet pipe relatively move close to shorten or eliminate the air break.
