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 the liquid level control method of an electronic toilet. Background technique [0002] The existing toilets mostly adopt a mechanical water level control method to control the liquid level of the toilet tank. Mechanical water level control is prone to failure. In the era of water conservation and environmental protection, the development and application of secondary water equipment is an inevitable trend. The secondary water toilet is the most suitable equipment for the application of secondary water. However, due to the poor cleanliness of the secondary water and a lot of debris, it will place higher requirements on equipment valves and pipe fittings. The mechanical water level control method is easy to be blocked when using secondary water, which affects the popularization and application of secondary water toilets.

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.
