an integrated circuit chip: an Integrated Circuit (IC) chip (Integrated Circuit Chip) is formed by placing a large number of microelectronic devices (transistors, resistors, capacitors, etc.) on a plastic substrate.

Ultrasonic liquid level meter: is a non-contact digital liquid level meter controlled by a microprocessor. In the measurement, ultrasonic pulses are emitted by a sensor (transducer), sound waves are received by the same sensor after being reflected by the surface of the liquid, the sound waves are converted into electric signals through a piezoelectric crystal, and the distance from the sensor to the surface of the liquid to be measured is calculated from the time between the emission and the reception of the sound waves. As non-contact measurement is adopted, the measured medium is almost unlimited, and can be widely used for measuring the heights of various liquid and solid materials.

Radar level gauge: the non-contact liquid level meter is based on the measuring instrument of time travel principle, radar wave operates at light speed, and the running time can be converted into material level signal through electronic component. The probe emits high frequency pulses that propagate in space at the speed of light, reflect back to be received by a receiver in the meter when the pulses encounter the surface of the material, and convert the distance signal into a level signal.

In a first aspect, embodiments of the present application provide a cleaning apparatus 100, which belongs to the technical field of the cleaning apparatus 100, and the cleaning apparatus 100 can determine whether a water tank 130 therein is in a liquid shortage state.
