For example, in some embodiments, the counterweight of the floor brush device 100 in the first area is larger than the counterweight in the second area, and the torsion force of the torsion spring 700 in the first area is smaller than that of the torsion spring 700 in the second area when the adapter 400 is in the same state; in other embodiments, the counterweight of the floor brush device 100 in the second area is larger than that in the first area, and the torsion force of the torsion spring 700 in the first area is larger than that of the torsion spring 700 in the second area when the adapter 400 is in the same state.

In order to realize the setting guide to two torsion springs 700 torsion, the specific embodiment of the present invention further provides the relationship between two torsion springs 700 torsion. The component force of the pressure of the torsion spring 700 on the base 104 in the first area in the vertical direction is F ₁ The component force of the pressure of the torsion spring 700 on the base 104 in the second area in the vertical direction is F ₂ The counterweight of the floor brush device 100 in the first area is M ₁ The counterweight of the floor brush device 100 in the second region is M ₂ Satisfy the provision of
