In summary, the cleaning storage seat 10 provided in this embodiment solves the problems that the existing cleaning appliance cannot be dried in time after use, and the brush head is prone to mold and smelly, and the charging and drying functions are integrated on the cleaning storage seat, which realizes convenient operation. After using the cleaning appliance 88, place the cleaning appliance 88 directly on the cleaning storage seat 10 and start the corresponding switch to achieve automatic charging, drying and other operations without human intervention. For example, referring to FIG. 16, the cleaning appliance 88 is placed in the cleaning storage seat 10 to directly activate the switch assembly, so that the control motherboard 300 receives the access signal from the switch assembly that corresponds to the cleaning appliance 88. Then, the operating status information of the cleaning appliance 88 is determined according to the access signal, and then the drying control signal is output according to the operating status information to start the air drying device 200 and the heating element 203 to dry the cleaning brush head 20. The above drying control signal can be a PWM control signal. The PWM control signal has strong noise resistance in signal transmission and can ensure the stability of signal transmission. Before the drying control signal is output according to the operating status information to dry the cleaning brush head 20, it can also be checked whether the input voltage is within the preset voltage range. If it is in the preset voltage range, it will judge the operating status information of the cleaning appliance 88 according to the access signal and output the drying control signal for drying processing. Otherwise, it will provide a voltage warning signal to indicate that the input voltage is abnormal, or directly use the control motherboard 300 to cut off the input voltage to prevent excessive input voltage from damaging the cleaning appliance 88, air drying device 200 and heating element 203.
Furthermore, the drying control device of the roller brush also comprises a current sampling module. The output terminal of the current sampling module is connected to the input terminal of the main control module. The current sampling module is used to obtain the drying working current when the drying device performs the drying process on the roller brush and then transmit it to the main control module. The main control module judges whether the current value is within the preset current range according to the information of the received drying working current. When the drying working current is too large, stop outputting the drying control signal to stop the drying treatment of the roller brush by the drying device, effectively preventing the burning of the device caused by the excessive drying working current.
It is worth mentioning that, please refer to FIG. 17, the cleaning appliance 88 is placed in the cleaning storage seat 10, In addition to the self-cleaning and drying function, when charging the cleaning appliance 88 and the backup battery 501, the control motherboard 300 can output a first charging control signal to charge the cleaning appliance 88 with the input voltage. Until the cleaning appliance 88 is fully charged, you can optionally output a second charging control signal to make the input voltage charge the backup battery 501. When the input voltage is cut off, the backup battery 501 can output the backup voltage as the input voltage to ensure the reliability of the power supply.
