Wherein the cutting speed is experimentally determined to be lower than the normal working speed to avoid damaging the cleaning brush and the cutting assembly 6 during the cutting process due to too fast rotation speed of the cleaning brush 2.
In the present embodiment, when the cutting assembly 6 moves to the cutting position, the method further includes: the control device 30 starts timing according to the in-place signal triggered by the driving mechanism 3, compares the timing length with the preset cutting time, and finishes the cutting task when the timing length is greater than or equal to the preset cutting time. Wherein, the cutting process lasts predetermines the cutting time and calculates according to cutting assembly 6's performance and reachs, can avoid predetermineeing the insufficient defect of cutting that the cutting time is too short to cause, can avoid predetermineeing the energy waste that the cutting time is too long to cause again to reach good cutting effect.
The control device 30 controls the driving mechanism 3 to drive the cutting assembly 6 to move from the non-cutting position to the cutting position according to the preset conditions and respectively combines the specific preset conditions to execute the cutting task; and after the cutting task is completed, the step of returning to the non-cutting position is described.
Specifically, taking a preset condition as an example that a measured value of a rotating speed of the driving device 9 driving the cleaning brush 2 to rotate is less than or equal to a preset rotating speed value, the control device 30 controls the driving mechanism 3 to drive the cutting assembly 6 to move from a non-cutting position to a cutting position according to the preset condition, and a cutting task is executed; and returning to the non-cutting position after the cutting task is completed, including: when the cleaning device 100 is started or cleaning is completed, the driving device 9 receives a rotation control signal of the cleaning brush 2 sent by the control device 30, and enters a corresponding rotation speed mode, so as to drive the cleaning brush 2 to enter a rotation state through the belt 12; meanwhile, the control device 30 obtains a rotation speed measurement value of the current rotation of the cleaning brush 2, and compares the rotation speed measurement value with a preset rotation speed value; if the measured value of the rotating speed is less than or equal to the preset rotating speed value, the control device 30 sends a first control signal to the power mechanism 4 of the driving mechanism 3, controls the power mechanism 4 to drive the connecting mechanism 5 to rotate, so that the cutting assembly 6 moves, and controls the driving device 30 to reduce the rotating speed of the cleaning brush 2 to the cutting rotating speed. In the moving process, when the detection mechanism 8 detects that the cutting assembly 6 reaches the cutting position, the detection mechanism 8 sends an in-place signal to the control device 30, and the control device 30 controls the power mechanism 4 to stop moving immediately according to the in-place signal, so that the cutting assembly 6 is ensured to be kept at the cutting position; at this time, the control device 30 triggers a cutting task of the cutting assembly 6 at the cutting position according to the in-place signal, that is, the cutting assembly 6 performs a cutting action on the elongated object on the circumferential end surface of the cleaning brush 2, meanwhile, the control device 30 triggers timing on the cutting task according to the in-place signal, and after the timing duration of the cutting task performed by the cutting assembly 6 reaches a preset cutting time, the control device 30 sends a second control signal, and the control device 30 controls the power mechanism 4 to drive the connecting mechanism 5 to rotate, so that the cutting assembly 6 moves to the non-cutting position.

The preset cutting time can be 30s or 1min, and can be set according to specific practical conditions. The cutting assembly 6 removes the elongated objects wound on the cleaning brush 2, thereby improving the cleaning effect of the cleaning device 100 and improving the use experience of users.
Taking the example that the rotation time of the cleaning brush 2 driven by the driving device 9 is greater than or equal to the preset rotation time, the control device 30 controls the driving mechanism 3 to drive the cutting assembly 6 to move from the non-cutting position to the cutting position according to the preset condition, and execute the cutting task; and returning to the non-cutting position after the cutting task is completed, including: when the host computer is started, the rotation time of the cleaning brush 2 is 10min, the control device 30 obtains the rotation time of the cleaning brush 2 all the time, and when the rotation time is longer than the preset rotation time of the cleaning brush 2, the control device 30 sends a first control signal to the power mechanism 4 of the driving mechanism 3, controls the power mechanism 4 to drive the connecting mechanism 5 to rotate, so that the cutting assembly 6 moves, and controls the driving device 30 to reduce the rotation speed of the cleaning brush 2 to the cutting rotation speed. In the moving process, when the detection mechanism 8 detects that the cutting assembly 6 reaches the cutting position, the detection mechanism 8 sends an in-place signal to the control device 30, and the control device 30 controls the power mechanism 4 to stop moving immediately according to the in-place signal, so that the cutting assembly 6 is ensured to be kept at the cutting position; at this time, the control device 30 triggers a cutting task of the cutting assembly 6 at the cutting position according to the in-place signal, that is, the cutting assembly 6 performs a cutting action on the elongated object on the circumferential end surface of the cleaning brush 2, meanwhile, the control device 30 triggers timing on the cutting task according to the in-place signal, and after the timing duration of the cutting task performed by the cutting assembly 6 reaches a preset cutting time, the control device 30 sends a second control signal, and the control device 30 controls the power mechanism 4 to drive the connecting mechanism 5 to rotate, so that the cutting assembly 6 moves to the non-cutting position. Meanwhile, after receiving the second control signal, the driving device 9 changes the operation mode, and drives the cleaning brush 2 to enter a normal operation speed through the belt 12, that is, enters a cleaning mode, and at this time, the cleaning device 100 performs floor cleaning.
