the driving circuit is connected with the main control module and the electric heating device and is used for driving the electric heating device to work;
the display interface is connected with the main control module and used for displaying prompt information for cleaning the scale;
and the alarm module is connected with the main control module and used for giving an alarm to remind a user of cleaning the scale.
15. The apparatus of claim 14, wherein the control unit is further configured to:
when the electric heating device is determined to be scaled, the electric heating device is controlled to stop working through the power supply, or the electric heating device is controlled to intermittently work through the power supply, or the working parameters of the electric heating device are reduced through the control of the driving circuit;
after the working state of the electric heating device is controlled and adjusted, the alarm module is controlled to give an alarm, and/or prompt information for cleaning the scale is displayed through the display interface.
16. The apparatus according to any one of claims 11-15, wherein the apparatus is an electrothermal humidifier.
17. A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, wherein the processor when executing the program implements a scale detection method as claimed in any one of claims 1 to 10.
18. A storage medium containing computer executable instructions for performing the scale detection method of any one of claims 1 to 10 when executed by a computer processor.
