Problems solved by technology

The current sweeping robots are equipped with water tanks in order to have a better dust removal and cleaning effect. However, the current sweeping robots cannot measure the height of the water level in the water tank and need to be checked manually. If the manual check is not timely, it will lead to water shortage, which will further Further affect the cleaning effect

Abstract

The invention discloses a liquid level measurement method in a water tank, which comprises the following steps: a sensor is built on the side wall of the water tank; a voltage balance electrode is arranged at the lowermost end of the sensor; a detection electrode is arranged above the voltage balance electrode, and the The electrodes are connected to the control circuit of the sensor through a high-resistance state; the control circuit determines whether the detection electrode is submerged or in contact by detecting the voltage value change on the electrode or the current change between the detection electrode and the voltage balance electrode; It is good to detect the position of the electrode and get the water level or water volume. The method of the present application utilizes the conductivity of water (except pure water), detects the change of resistance between electrodes through a control circuit, and obtains the water level.

Description

technical field [0001] The invention relates to the technical field of sweeping robots, in particular to a liquid level measurement method in a water tank. Background technique [0002] The sweeping robot, also known as the lazy sweeper, is a smart household appliance that can automatically vacuum the ground. Because it can detect factors such as room size, furniture placement, and floor cleanliness, and rely on the built-in program to formulate a reasonable cleaning route, with certain intelligent effects. In order to have better dust removal and cleaning effect, the current sweeping robots are equipped with water tanks, but the current sweeping robots cannot measure the height of the water level in the water tank and need to be checked manually. further affect the cleaning effect. SUMMARY OF THE INVENTION [0003] The present invention provides a method for measuring the liquid level in a water tank, in order to solve the problems existing in the background technology....
