Description
Technical Field
The invention relates to the field of bathroom, in particular to a washing surface flushing structure of a low-water tank closestool.
Background
Along with the development of the world economic level, the living standard of people is continuously improved, the requirements of people on living quality are also higher and higher, and the toilet bowl is used as a living article commonly used in modern families, and the appearance and usability of the toilet bowl are more and more valued by people.
The early-stage closestool adopts a traditional gravity drainage mode to realize flushing of the cleaning surface of the closestool, the position of the water tank is required to be set higher, the water flow in the water tank can have a larger flow speed to flow into the water guide ring at the top of the closestool urinal by utilizing the height difference, and then the water flows onto the cleaning surface of the closestool from the water guide ring to flush the cleaning surface of the closestool.
For aesthetic purposes and space saving of toilets, low tank toilets have been developed, which currently have a tank usually located at the rear of the toilet slightly below the seat of the toilet. When the water tank is sunk to the bottom of the water tank below the upper edge of the seat ring, the flushing of the cleaning surface of the toilet can obviously not be realized by adopting a traditional gravity drainage mode. The prior art adopts a brush ring injector with a negative pressure principle, water in a water tank is extracted into a water guide ring with higher level by the kinetic energy of tap water and then flows into a cleaning surface, so that the cleaning surface is flushed, and the structures are disclosed in Chinese patent CN201810205829.3 and Chinese patent CN 201810205829.3. At present, a water inlet of a brush ring ejector is communicated with a water inlet valve of a closestool, a water outlet of the brush ring ejector is communicated with a water guide ring, a switching mechanism for controlling the water supply quantity of the brush ring ejector to the water guide ring is arranged on the brush ring ejector, the switching mechanism comprises a switching baffle for controlling the water outlet quantity of the brush ring ejector in a rotating mode and a power mechanism for driving the switching member to rotate, and the power mechanism is controlled by the water level in a water tank to drive the switching baffle to rotate; when the toilet needs to be washed, the switching mechanism opens the brush ring injector, and water flow from the water inlet valve drives water flow in the water tank to flow into the water guide ring under the action of negative pressure, so that water is supplied to the water guide ring, and water flow in the water guide ring flows onto the toilet washing surface again to wash the toilet washing surface. When the water tank needs to store water, the switching mechanism reduces the water supply amount of the brush ring ejector to the water guide ring, so that most or all water flow of the water inlet valve flows into the water tank to store water.
However, the brush ring ejector is used for realizing that the water tank of the low water tank toilet flushing the cleaning surface has less water drawn from the water tank when the pressure of a tap water pipeline is lower than 0.12MPa, so the effect of cleaning the cleaning surface of the toilet is also common.
