  • the second end of the tilt sensor 810 is grounded, and the resonant circuit is also connected to the control circuit 400 .
  • the sensor circuit 800 can be used to detect the inclination angle of the chassis mechanism 100 and the preset plane, thereby allowing the control circuit 400 to control the floor washing machine 1000 to avoid the chassis mechanism 100 and the machine having been stored after the floor washing machine 1000 has been stored. When the body 200 is placed vertically, the operator mistakenly operates the operating switch, causing the floor washing machine 1000 to operate, resulting in damage to the floor washing machine 1000 or water leakage.
