The handle portion 121 is configured to be held by a user to operate the surface cleaning apparatus 1. The handle portion 121 is further provided with a cleaning switch 124 and a self-cleaning switch 125, the cleaning switch 124 is used for a user to start a cleaning procedure of the surface cleaning device 1, and the self-cleaning switch 125 is used for the user to start a self-cleaning procedure of the surface cleaning device 1
The fluid supply system includes a supply tank 131 for storing and supplying the cleaning liquid to the outside, an infusion path (not shown) between the supply tank 131 and the roller brush 112, and a pump 132 located on the infusion path.

The surface cleaning apparatus 1 further includes a rechargeable battery pack 151, a charging plug 153, and a charging circuit 152 (see fig. 4) located between the rechargeable battery pack 151 and the charging plug 153.

As shown in fig. 4, the controller 16 is located inside the surface cleaning apparatus 1 and can be triggered to run a cleaning program, in this case both the cleaning switch 124 and the self-cleaning switch 125 are coupled to the controller 16. In this example, when the cleaning switch 124 is pressed, the controller 16 will run a cleaning program in which the controller 16 simultaneously activates the roller brush motor 114, the pump 132, and the suction motor 142. The cleaning liquid in the supply tank 131 reaches the fluid dispenser through the liquid delivery path by the pump 132 and is dispensed onto the roller brush 112 via the fluid dispenser; the roller brush 112 driven by the roller brush motor 114 performs a cleaning operation on the contacted surface to be cleaned with a cleaning liquid; the suction motor 142 forms a negative pressure on a recovery path from the lower opening of the roller brush chamber 116 to the recovery tank 141, and the contaminated liquid passing through the recovery path reaches and is stored in the recovery tank 141 by the negative pressure in the recovery path 142.
The controller 16 can be triggered to run a self-cleaning program. In this example, when the self-cleaning switch 125 is pressed, the controller 16 will run the self-cleaning program; the controller 16, when running the self-cleaning program, will transmit corresponding control signals to the brush motor 114, the pump 132 and the suction motor 142, respectively, in stages. In an embodiment, the controller 16 is triggered to start the self-cleaning procedure, or the controller 16 may be triggered to operate by itself after the internal set operating conditions are met, or may be triggered by receiving a trigger command from the outside.
As shown in fig. 5, the charging circuit 152 is coupled to the rechargeable battery pack 151 to supply a charging current to the rechargeable battery pack 151. The charging circuit 152 includes an input terminal 1521, an output terminal 1522, a first current path 1523 between the input terminal 1521 and the output terminal 1522, and a second current path 1524 between the input terminal 1521 and the output terminal 1522.
When a predetermined current I 0 (for example, the predetermined current is a supply current from the charger input of the tray 2) is input from the input terminal 1521 and passes through the first current path 1523, the output terminal 1522 outputs the first charging current I 1; when a predetermined current I 0 is input from the input terminal 1521 and routed through the second current path 1524, the output terminal 1522 outputs a second charging current I 2 which is less than the first current I 1.
The controller 16 is coupled to the charging circuit 152 to transmit a first signal to the charging circuit 152 that opens the first current path 1523 and closes the second current path 1524 or a second signal to open the second current path 1524 and close the first current path 1523.
As shown in fig. 6, a charging circuit of an embodiment is provided with a current limiting resistor 1525 and a MOS transistor Q1.JP2 is connected to a power supply circuit for supplying power to the charging circuit 152, JP3 is connected to the rechargeable battery pack 151, and JP4 is connected to a control signal of the controller 16.
When JP4 receives the control signal from the controller 16 to control the MOS transistor Q1 to be turned on, the JP4 output voltage controls the U1 optocoupler to be turned on, so that the R1 and the R2 are divided to turn on the Q1, the charging circuit passes through the Q1, the second current path 1524 is turned off, the predetermined current input by the input terminal 1521 does not pass through the current limiting resistor 1525, and the predetermined current input by the input terminal 1521 passes through the first current path 1523 and outputs the first charging current I 1 through the output terminal 1522. When JP4 receives the control signal from the controller 16 to control the MOS transistor Q1 to be turned off, JP4 does not output a voltage, the U1 optocoupler is not turned on, R1 and R2 do not form a divided voltage, Q1 is turned off, and a predetermined current can only pass from the current limiting resistor 1525 of the second current path 1524, thereby reducing the charging current value output from the output terminal 1522 to the second charging current I 2.
In this example, the controller 16 transmits a second signal to the charging circuit 152 when running the self-cleaning program, that is, when self-cleaning, controls the MOS transistor Q1 to be turned off, and the charging current passes through the current limiting resistor, thereby reducing the charging current. When the self-cleaning procedure is finished, the controller 16 selects to transmit the first signal to the charging circuit 152, i.e. to resume normal charging, at this time, the controller 16 will control the MOS transistor Q1 to be turned on, and the charging current does not pass through the current limiting resistor 1525.
In order to ensure the use safety of the rechargeable battery pack during self-cleaning, the controller 16 has a maximum operating current I max of the brush motor 114, the pump 132 and the suction motor 142 when running the self-cleaning program, and the value of the second charging current I 2 is set to be smaller than the value of the maximum operating current I max; the second charging current I 2 may be set to 40 milliamps or less.
The process of the surface cleaning apparatus 1 running the self-cleaning procedure will now be described. After the surface cleaning apparatus 2 is parked on the tray 2, the controller 16 is triggered to start the self-cleaning procedure, at this time, the controller 16 transmits a second signal to the charging circuit 152 to disconnect the first current path 1523 and connect the second current path 1524, the preset current output by the tray 2 is input from the input terminal 1521 of the charging circuit 152, passes through the second current path 1524 and outputs the second charging current I 2 to the rechargeable battery pack 151 through the output terminal 1522; on the other hand, the controller 16 sets up the self-cleaning program to start the rolling brush motor 114, the pump 132 and the suction motor 142 in sequence to operate; after a self-cleaning procedure is completed, the controller 16 will immediately transmit a first signal to the charging circuit 152 to disconnect the second current path 1524 and connect the first current path 1523, the preset current output from the tray 2 will be input from the input terminal 1521 of the charging circuit 152, the second charging current I 1 is output to the rechargeable battery pack 151 through the output terminal 1522 via the first current path 1523, and after that, after the charge of the rechargeable battery pack 151 is full, the controller 16 controls the charging circuit 152 to be turned off.
The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention.
