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 method for measuring the liquid level in a water tank. The method comprises the following steps that a sensor is arranged in the side wall of the water tank; a voltage balance electrode is arranged at the lowermost end of the sensor; detecting electrodes are arranged above the voltage balance electrode, and the detecting electrodes are connected to a control circuit of the sensor through a high resistance state; the control circuit judges whether the detection electrode is submerged by water or is in contact with the detection electrode according to the change of the voltage value on the detection electrode or the change of the current between the detection electrode and the voltage balance electrode; and the water level or the water quantity is obtained through the predetermined position of the detection electrode. According to the method, the electrical conductivity of water (except purified water) is utilized, the resistance change condition between the electrodes is detected through the control circuit, and the water level is obtained.

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 built-in programs to formulate reasonable cleaning routes, it has certain intelligent effects. The current sweeping robots are equipped with water tanks in order to have a better dust removal and cleaning effect, but the current sweeping robots cannot measure the height of the water level in the water tank and need to be manually checked. If the manual check is not timely, it will lead to water shortage, which will further Further affect the cleaning effect. Contents of the invention [0003] The invention provides a liquid level measurement method in a water tan...
