An acquisition resistor can be arranged in the rolling brush current acquisition module 19 to acquire the current flowing through the rolling brush 111. The control module 10 judges the rolling brush 111 current signal acquired by the rolling brush current acquisition module 19. If the rolling brush 111 current signal exceeds the second preset threshold, the control module 10 controls the rolling brush control module 11 to control the rolling brush 111 to stop working. The second preset threshold can be set according to actual application.

[0054] Further, an alarm module can be arranged in the floor mopping machine. If the control module 10 judges that the rolling brush 111 current signal exceeds the second preset threshold, the control module 10 controls the alarm module to alarm.

[0061] The second sensor 211 can be any kind of sensor, and exemplarily, the second sensor 211 is a Hall sensor, and the water tank in the embodiment can be a sewage tank or a clean water tank.

[0062] The second preset position can be set according to actual application. For example, the second sensor 211 is arranged at a water tank placement position of the floor cleaning machine.

The input end of the floor cleaning machine state detection module 22 is connected with a spring switch 221 arranged at a third preset position of the floor cleaning machine. The output end of the floor cleaning machine state detection module 22 is electrically connected with the control module 10. The control module 10 is used to determine whether the floor cleaning machine is in a preset state according to the state detection signal of the floor cleaning machine state detection module 22. If it is determined that the floor cleaning machine is in the preset state, the control module 10 controls the floor cleaning machine to stop cleaning.

[0065] The third preset position can be set according to actual application.

[0066] For example, the preset state is a vertical state. The control module 10 determines whether the floor cleaning machine is in the vertical state according to the state signal of the floor cleaning machine state detection module 22. If it is determined that the floor cleaning machine is in the vertical state, the control module 10 controls the floor cleaning machine to stop cleaning. Further, the control module 10 can lock the floor cleaning machine when it is determined that the floor cleaning machine is in the vertical state, so that the user cannot start the floor cleaning machine through the start button.

[0067] The control circuit of the floor cleaning machine in this embodiment is arranged with the spring switch 221 on the floor cleaning machine.

The floor cleaning machine is prevented from tilting when working, the surrounding environment is prevented from being damaged, and the safety of the floor cleaning machine is ensured.

[0068] In an embodiment, the control circuit of the floor cleaning machine further includes a voltage stabilizing module. The input end of the voltage stabilizing module is connected with the charging battery 15.

The input end of the second pull-up unit is used to connect to the power supply. The other end of the energy storage unit is electrically connected to the control module 10.

[0073] Exemplarily, the energy storage control unit is a triode Q14. When the floor mopping machine obtains the charging signal, the charging signal flows to the control end of the triode Q14 after being divided by the resistors R80 and R81. The triode Q14 is turned on, the voltage at one end of the capacitor C59 of the energy storage unit is pulled down, the capacitor C59 of the energy storage unit is charged by using the resistor R42 of the second pull-up unit to connect the power supply signal MCU VCC, and then the voltage input to the control module 10 is lowered.
