Electronic closestool provided with liquid level sensor and preventing liquid level from fluctuating

Abstract

An electronic closestool provided with a liquid level sensor and preventing a liquid level from fluctuating comprises the liquid level sensor, a closestool inflow assembly and a control circuit, wherein the closestool inflow assembly comprises a vertically arranged water inlet assembly and a liquid level sensor fixing frame connected to the position above the water inlet assembly. The water inlet assembly is provided with a tubular main body which is through from top to bottom, a lower pipe opening of the tubular main body is a water inlet, and an upper pipe opening of the tubular main body is a water outlet. The fixing frame is provided with a cylindrical casing, an inner cavity is divided into an upper cavity body and a lower cavity body which are not communicated with each other through a horizontal partition wall, a plurality of through holes are evenly distributed on the cylindrical casing, water flow can flow into and out of the fixing frame through the through holes, and the liquid level sensor is fixed on the liquid level sensor fixing frame. The liquid level sensor is adopted to serve as a control device of the water tank liquid level, an inflow structure is improved simultaneously so that the water level rises gently, severe fluctuation is avoided, and misoperation of the liquid level sensor is reduced.

Description

technical field [0001] The invention relates to the technical field of toilets, in particular to a liquid level control method of an electronic toilet. Background technique [0002] Existing toilet mostly adopts the liquid level height that is mechanical water level control mode to control the toilet water tank. Mechanical water level control methods are prone to failure. In the current situation of saving water and promoting environmental protection, it is an inevitable trend to develop and apply secondary water equipment. The secondary water toilet is the most suitable equipment for the application of secondary water. However, because the cleanliness of the secondary water is poor and contains a lot of debris, it will impose higher requirements on the valves and fittings of the equipment. However, the mechanical water level control method is easy to block when using secondary water, thereby affecting the popularization and application of secondary water toilets. [000...

AI Technical Summary

Problems solved by technology

The water level sensor is easily affected by the fluctuation of the water level and the accuracy of the detection is affected. However, the existing toilet water intake method is to flow upward from the bottom water inlet pipe into the water tank. When the water pressure is high, the water intake fluctuates greatly, and the water level sensor will easily cause misoperation.
