Description

Switch out water installation and closestool thereof Technical Field The utility model belongs to the technical field of bathrooms, and particularly relates to a water outlet switching device and a closestool thereof. Background When some toilets are used for flushing dirt, the liquid paths need to be switched through the switching mechanism so as to clean the pan surface of the toilet and discharge the dirt out of the toilet. However, the switching mechanism generally needs to be driven by an electric control assembly, so that the cost is high, and the electric control assembly needs to be in a dampproof and water leakage-proof structure, so that the cost is further increased. In order to solve the problems, the Chinese patent document CN117926890A discloses a liquid path switching mechanism, a flushing device and a closestool, wherein the liquid path switching mechanism comprises a shell component, a reset piece and a movable component. Wherein, the movable assembly can enclose into first cavity with the casing subassembly. The movable assembly is driven by the resetting piece to disconnect the second liquid outlet channel from the first cavity, and can move relative to the mounting cavity under the action of liquid with the liquid pressure in the first cavity being greater than or equal to a preset value, so that the resetting piece generates the driving force for resetting the movable assembly, the first liquid outlet channel can be used for discharging liquid and the second liquid outlet channel is stopped from discharging liquid when the liquid pressure in the first cavity is lower than the preset value, and the liquid pressure in the first cavity is greater than or equal to the preset value and is switched into the first liquid outlet channel and the second liquid outlet channel to be discharged simultaneously, so that the switching of liquid paths is realized by utilizing the liquid pressure change in the first cavity, and the switching of non-electric control is realized, so that the cost is reduced, but the liquid path switching mechanism has no function of discharging foam water, has no foam isolation function and needs to be further improved.
