Toilet stool and control method thereof
InactiveCN112144625AReduce flushing water consumptionClean upWater closetsMechanical energy handlingFecesWater rinsing
The invention belongs to the field of bathroom accessories, and particularly discloses a toilet stool and a control method thereof. The toilet stool comprises a shell, a control module, a conveying assembly arranged in the shell and a water spraying assembly; the shell comprises a sewage inlet and a sewage outlet communicated with a drainage pipeline; the conveying assembly comprises a bearing part and a transmission part, the bearing part is used for receiving dirt falling from the dirt inlet, and the control module is used for controlling the transmission part to rotate to drive the bearingpart, so that the bearing part moves around the transmission part, and the dirt falls from the bearing part to enter the dirt outlet; and a water spraying port of the water spraying assembly faces thebearing surface of the bearing part. Most excrement such as faeces falls into a sewer line under the action of gravity through movement of the bearing part, only a small amount of water is needed forflushing, a small amount of residual excrement remains, the water consumption for flushing the toilet is reduced, meanwhile, the problem that the toilet cannot be flushed cleanly or even cannot be flushed is solved, and spreading of infectious viruses, bacteria and the like is prevented to a certain extent.

ActiveCN105525665BSpeed up dischargeReduce flushing water consumptionLavatory sanitoryWater useSiphon
The invention discloses a closestool washing water way structure capable of accelerating siphon and a toilet seat. The closestool washing water way structure comprises a common water way arranged in the toilet seat, a washing ring water way for providing water to a closestool washing ring, and a spray water way for providing water to a closestool spray hole, wherein the front end of the common water way is communicated with a water inlet of the toilet seat, the rear end of the common water way forms split-flows and is respectively communicated with an inlet end of the washing ring water way and an inlet end of the spray water way, the common water way is internally provided with a flow guide structure for preferentially guiding the water flow into the spray water way, so that most of the air in the spray water way enters the washing ring water way and is exhausted from a washing ring hole along the washing ring water way before washing is carried out, therefore, the influences of the air to the potential energy of the water flow is reduced, the exhausting speed of the air in the spray water way is improved, the early formation of spray siphon is facilitated, and the water use amount for washing is reduced.
