Description

Technical Field

[0001] The utility model relates to the technical field of descaling and flow stabilizing devices, in particular to a self-cleaning flow stabilizing device, an intelligent cover plate and a toilet bowl. Background Art

[0002] When the water for the flushing end passes through the filter element, after long-term use, sediment impurities are likely to block the water inlet or outlet of the filter element, resulting in a decrease in the water inlet flow rate and the inability to flush the toilet properly.

[0039] a flow limiter, disposed at the water purification outlet 102, the flow limiter adjusts the size of the water passing cross-sectional area of the water purification outlet 102 based on the magnitude of the water outlet pressure; and

[0040] a switching valve, disposed in the sewage outlet 103, for opening or closing the sewage outlet 103;

[0041] As Figures 7-8As shown in the figure, when the switching valve opens the sewage outlet 103, the filtering component presses the first elastic member 204 under the action of the inlet water pressure, so that the filtering component is in the first state where the backwashing channel is communicated with the water inlet 101; when the switching valve closes the sewage outlet 103, the filtering component moves to the second state where the backwashing channel is not communicated with the water inlet 101 under the elastic force of the first elastic member 204.

[0042] Specifically, when the switching valve opens the sewage outlet 103, the filtering component presses the first elastic member 204 and moves towards the sewage outlet 103 until it is in the first state where the water inlet 101 is communicated with the first water passing hole 2021. The water flow at the water inlet 101 flows into the filtering component from the second water passing hole 2012 and the first water passing hole 2021, flushes the filtering component and then flows out from the sewage outlet 103; when the switching valve closes the sewage outlet 103, the filtering component is pressed by the first elastic member 204 and moves towards the clean water outlet 102 until it is in the second state where the water inlet 101 and the first water passing hole 2021 are not communicated with each other.
