By making the rotation stopper structure 500 include the rotation stopper protrusion 510 fixedly disposed in the inner cavity of the floor brush body 100, when the rotation shaft limiting protrusion 2142 rotates to the horizontal position, the rotation stopper protrusion 510 can block the rotation shaft limiting protrusion 2142, so that the rotation shaft body 214 is maintained at the position and does not rotate any more. Also, by setting the rotation stopper protrusion 510 to have an arc-shaped structure, the rotation stopper protrusion 510 may gradually block the rotation axis restricting protrusion 2142; meanwhile, the rotation shaft limiting protrusion 2142 may also be correspondingly configured to have an arc-shaped structure. In addition, the rotation stopper protrusion 510 may be an arc protrusion, a trapezoid protrusion, or a protrusion with other shapes; the shape of the rotation shaft limiting protrusion 2142 corresponds to the shape of the rotation stopper protrusion 510.

In this embodiment, the rotation stopper protrusion 510 may be coupled to the first elastic expansion member 520, such that the rotation stopper protrusion 510 is telescopically movably disposed. Thus, when the rotation stopper protrusion 510 receives a large pressing force, the rotation stopper protrusion 510 may press the first elastic expansion member 520 to compress the rotation stopper protrusion 510, so that the rotation stopper protrusion 510 may contract, and the rotation stopper protrusion 510 may be separated from the rotation shaft limiting protrusion 2142, so that the rotation shaft body 214 may rotate to pass through the position of the rotation stopper structure 500, and the rotation angle of the cleaning apparatus main body 10 may be enlarged.

Thus, when the rotation shaft limiting protrusion 2142 rotates along with the rotation shaft body 214 to contact with the rotation stopper protrusion 510, the friction acting force of the rotation stopper protrusion 510 on the rotation shaft limiting protrusion 2142 is F1, the cleaning device main body 10 can be in a stable standing state, and at this time, the device can be shut down and stand still; when the cleaning device needs to be started up to clean the floor, the cleaning device main body 10 is pulled backward by the handle on the top of the cleaning device main body 10, and at this time, the acting force applied to the rotation limiting protrusion 2142 is greater than the friction acting force F1, so that the rotation stopper protrusion 510 overcomes the acting force of the first elastic expansion element 520 to contract, the rotation shaft body 214 rotates past the position of the rotation shaft limiting protrusion 2142, and thus the rotation shaft can rotate freely again, and the rotation shaft limiting protrusion 2142 can be restored to the maximum position under the elastic force of the first elastic expansion element 520. When the cleaning device main body 10 needs to be adjusted to a standing state, the handle at the top of the cleaning device main body 10 can be held and pushed forward with force, so that the rotation stopper protrusion 510 contracts against the action force of the first elastic expansion piece 520, the rotation shaft body 214 rotates, the rotation shaft limiting protrusion 2142 rotates to a corresponding position in an upright state, the friction action force of the rotation stopper protrusion 510 on the rotation shaft limiting protrusion 2142 is F1, and the cleaning device main body 10 is in a stable standing state. The rotation axis body 214 and the cleaning device main body 10 can be limited by the rotation stopper structure 500, so that the cleaning device main body 10 keeps a standing posture; meanwhile, the cleaning device main body 10 can be maintained at a large rotation angle, so that the brush assembly 20 can have a large cleaning angle.

Specifically, two limit baffles may be protruded side by side on the bottom wall of the inner cavity of the floor brush, so that the elastic limit groove 102 is defined between the two limit baffles. Moreover, the aforementioned limit groove cover plate can limit the first elastic expansion element 520 from above, and the first elastic expansion element 520 can be limited from the end portion by the cover plate mounting seat, and it is also convenient to assemble and disassemble the limit groove cover plate 104 and the first elastic expansion element 520 by the cover plate mounting seat and the cover plate connecting member. In addition, in this embodiment, the cover plate connector may be a connection screw passing through the limiting groove cover plate 104 and the cover plate mounting seat; the first elastic expansion member 520 may be an expansion spring.

In addition, in some embodiments, the rotation shaft limiting protrusion 2142 may include an arc-shaped limiting protrusion block disposed on the rotation shaft body 214, and the rotation stopper protrusion 510 is correspondingly engaged with the limiting protrusion block. The rotating shaft limiting protrusion 2142 can include a limiting protrusion block fixedly disposed on the rotating shaft body 214, such that when the limiting protrusion block rotates to a certain angular position, the rotating stop protrusion 510 can block the limiting protrusion block, and the rotating shaft body 214 can be maintained at the position and can not rotate.
