When the tilt angle is greater than the preset angle threshold, the floor washing machine 1000 can be considered to be in a stowed state, that is, the chassis mechanism 100 and the body 200 of the floor washing machine 1000 are approximately When the tilt angle is less than or equal to the preset angle threshold, the floor washing machine 1000 can be considered to be in a running state, that is, the chassis mechanism 100 and the body 200 of the floor washing machine 1000 are placed vertically. Among them, the preset plane can be the ground or a horizontal plane.

Since the inclination angle of the chassis mechanism 100 can be detected through the sensor circuit 800, the control circuit 400 can control the on/off load of the floor washing machine 1000 according to the inclination angle of the chassis mechanism 100 and the preset plane, thus controlling the floor washing machine 1000. The working status is trial operation or closed. This avoids the problem of malfunction of the machine due to improper operation by the operator when the operation switch is triggered when the floor washing machine 1000 is in an upright state, that is, when the inclination angle of the chassis mechanism 100 is greater than the preset angle threshold, thereby avoiding damage to the floor washing machine 1000. .

Specifically, the sensor circuit 800 may include a tilt sensor 810, an angle sensor or a gravity sensor, etc., and may detect the tilt angle formed between the chassis mechanism 100 and a preset plane. The control circuit 400 may be a circuit including a control chip, and is used to control the conduction and disconnection of all load devices of the floor scrubber 1000 according to the electrical signal input to the control circuit 400 through the sensor circuit 800 .

When the control circuit 400 receives the electrical signal input through the sensor circuit 800, it can determine the tilt angle formed between the chassis mechanism 100 and the preset plane according to the input electrical signal, and then control the floor washing machine 1000 according to the tilt angle. Switching between various loads. For example, if the tilt angle is greater than the preset angle threshold, the disconnection between the loads of the floor washing machine 1000 is controlled; if the tilt angle is less than or equal to the preset angle threshold, the conduction between the loads of the floor washing machine 1000 is controlled.

If the tilt sensor 810 detects that the angle between the chassis mechanism 100 and the preset plane is less than or equal to the preset angle threshold, the internal tilt switch is closed. At this time, the first resistor 820 and the second resistor 831 are connected in parallel. At this time, the control circuit 400 can obtain the same electric energy as the electric energy provided by the battery 1191, that is, it receives a high-level signal. At this time, the control circuit 400 can control all the loads in the floor washing machine 1000 to turn on. The resistance values of the first resistor 820 and the second resistor 831 may be the same or different, and are not limited here.

Optionally, the preset plane may be a horizontal plane, or the floor washing machine 1000 may be placed on the plane where the plane to be cleaned is located during operation, which is not limited here.

The devices (for example, the fan 710, the driving part 180, the display part 212, and the solenoid valve) are controlled on and off. For example, the fan 710, the driving part 180, and the solenoid valve can be turned off, so that only the display part 212 of the floor washing machine 1000 can operate. display, but cannot work, thus it will not cause water leakage, etc. In other embodiments, only the driving part 180, solenoid valve, etc. can be disconnected. In other embodiments, the entire floor washing machine 1000 can also be controlled to be powered off. , making the floor washing machine 1000 unable to be turned on, etc.; there are no restrictions here.

Specifically, the main control switch 191 can be connected to the control circuit 400 to control the switch of the entire circuit board 190 . It is also possible to independently connect multiple electrical devices (for example, the fan 710, the driver 180, the display unit 212, the solenoid valve), etc., and independently control the shutdown of a certain electrical device, which is not limited here.

As an embodiment, the circuit board 190 is installed on the base body 112 and located below the battery 1191 , that is, optionally, the circuit board 190 is located on the side of the battery 1191 away from the fuselage 200 . By arranging the circuit board 190 below the battery 1191, this layout method can not only reduce the length of the wiring, but also save the volume of the layout chassis mechanism 100 (the layout space is smaller due to the interference of the driving member 180).

In this embodiment, since the sensor circuit 800 is introduced into the floor washing machine 1000, and there is a tilt sensor 810 connected to the control circuit 400 in the sensor circuit 800, it also includes a first resistor 820 and a resonant circuit.
