In view of this, the present utility model proposes a cleaning apparatus, and fig. 1 to 5 are an embodiment of the present utility model.

Referring to fig. 1 to 4, the cleaning apparatus 100 includes a housing 1 and a cleaning structure 3, wherein a via hole 2 is formed on a lower side of the housing 1; the cleaning structure 3 comprises a cleaning part 31 and a connecting part 32 arranged on the upper side of the cleaning part 31, wherein the connecting part 32 is movably arranged at the through hole 2 along the up-down direction, an inclined plane 4 is formed on the connecting part 32, and the cleaning part 31 is provided with a ground-leaving position for separating from the ground and a cleaning position for abutting against the ground in the moving stroke; the driving structure 5 includes a first driving member 51 and a second driving member 52, the first driving member 51 includes a driving portion 511 that rotates along an up-down extending axis, the driving portion 511 abuts against the inclined surface 4, the driving portion 511 can drive the cleaning portion 31 to move from the off-position to the cleaning position in a moving stroke of the driving portion 511, and the second driving member 52 is used for driving the cleaning portion 31 to move from the cleaning position to the off-position; the limiting structure 6 is disposed between the housing 1 and the connecting portion 32, and is used for limiting the connecting portion 32 to rotate when the cleaning portion 31 moves between the ground-leaving position and the cleaning position.

In the technical solution of the present utility model, when the cleaning apparatus 100 is in the inactive state, the second driving member 52 drives the cleaning portion 31 to be located at the ground-leaving position, at this time, the driving portion 511 abuts against the inclined surface 4 of the connecting portion 32, and when it is understood that, when in the ground-leaving position, the driving portion 511 is located at a lower position of the inclined surface 4, and when the driving portion 511 works, it rotates along an up-down axis, at this time, because the limiting structure 6 limits the connecting portion 32 to rotate, during the rotation of the driving portion 511, the driving portion 511 abuts against the inclined surface 4 and pushes the connecting portion 32 to move downward, thereby driving the scenario portion to move to the cleaning position, and correspondingly, at this time, the driving portion 511 is located at a lower position of the inclined surface 4; when the driving part 511 stops working, the second driving member 52 can automatically drive the cleaning part 31 to move from the cleaning position to the ground-leaving position; compared with the prior art that the screw thread structure is adopted to control the up-and-down movement of the mop, the utility model adopts the rotation mode of the driving part 511 to be abutted against the inclined surface 4, so that the friction resistance when the cleaning part 31 is driven to move downwards can be reduced, and the abrasion of the structural components is not easy to occur.

The inclined surface 4 may be an inclined surface formed directly at the upper end of the connecting portion 32, or may be a rail; specifically, in an embodiment of the present utility model, the connecting portion 32 extends in a vertical direction and is provided in a cylindrical shape, the connecting portion 32 is provided with a first rail 4a along a circumferential direction thereof, and the first rail 4a is provided obliquely in a vertical direction to form the inclined surface 4; correspondingly, the driving part 511 abuts against the first rail 4a.

By providing the first stopper 61 and the second stopper 62 to stop on a path along which the connection portion 32 is to be rotated, the connection portion 32 is restricted from rotating simultaneously with the driving portion 511 when the driving portion 511 rotates, so that the cleaning portion 31 can be switched between the off-floor position and the cleaning position.

Further, when the cleaning unit 31 is located at the cleaning position, the cleaning unit 31 may be rotated by an external structure or the driving unit 511 may be rotated by the rotation; specifically, in an embodiment of the present utility model, the driving part 511 is configured to drive the cleaning part 31 to rotate, specifically, the connecting part 32 is further configured with a second guide rail 7 around its circumference, the second guide rail 7 is connected to the first guide rail 4a, at least part of the second guide rail 7 is disposed obliquely upward and downward, and the driving part 511 can slide into the second guide rail 7 from the first guide rail 4 a; when the driving unit 511 is located on the second rail 7, the first stopper 61 and the second stopper 62 are vertically offset from each other. When the driving unit 511 moves along the first rail 4a to the second rail 7, the second rail 7 is continuously inclined vertically, and when the driving unit is on the second rail 7, the first stopper 61 and the second stopper 62 are displaced vertically, so that the first stopper 61 and the second stopper 62 cancel the contact, the connecting unit 32 is rotatable, and the driving unit 511 can contact the second rail 7, and the cleaning unit 31 can be driven to rotate by the friction between the driving unit 511 and the second rail 7, thereby cleaning.

Further, in order to achieve a better effect of driving the cleaning portion 31 to rotate, the connection portion 32 is provided with a protrusion 8 protruding upward from the second rail 7 on the second rail 7, and the protrusion 8 abuts against the driving portion 511 in the circumferential direction of the connection portion 32, so that the driving portion 511 can drive the connection portion 32 to rotate together. When the convex portion 8 is provided on the second rail 7, the driving portion 511 abuts against the convex portion 8 when the driving portion 511 rotates and moves along the second rail 7, so that the connecting portion 32 can rotate along with the driving portion 511.

Further, the positions where the first rail 4a and the second rail 7 are formed are not limited, and may be on the peripheral side of the connecting portion 32 or may be on the upper end of the connecting portion 32; specifically, in an embodiment of the present utility model, the first rail 4a and the second rail 7 are both disposed at the upper end of the connecting portion 32. By arranging the first guide rail 4a and the second guide rail 7 at the upper end of the connecting portion 32, the connecting portion 32 is convenient to be formed.

By providing the two guide surfaces 9, the driving part 511 can drive the connecting part 32 to move up and down, regardless of forward rotation or reverse rotation.

It will be appreciated that, since the second guide rail 7 is connected to the first guide rail 4a, the number of the second guide rails 7 corresponds to the number of the first guide rails 4a.

Referring to fig. 2 to 3, in an embodiment of the present utility model, the second driving member 52 includes a spring 521 and a spacer 522, and the spring 521 is installed between the lower end portion of the connecting portion 32 and the housing 1; the washer 522 is installed between the spring 521 and the connection portion 32. When the driving part 511 drives the cleaning part 31 to move from the off-position to the cleaning position, the spring 521 is compressed, and when the driving part 511 stops working, the spring 521 returns to the original shape and drives the cleaning part 31 to move from the cleaning position to the off-position, and the pad 522 is arranged to separate the spring 521 from direct contact with the connecting part 32, so that friction is transferred to a contact part between the pad 522 and the connecting part 32 and between the pad 522 and the connecting part 32 as an arc surface when the connecting part 32 rotates, thereby reducing the contact surface and further reducing the friction resistance.

In another embodiment of the present utility model, the second driving member 52 includes two magnets, which are separately disposed on the connecting portion 32 and the housing 1 and repel each other in the up-down direction, so as to drive the connecting portion 32 to move upward. That is, the cleaning portion 31 can be driven to move from the cleaning position to the ground-leaving position by the mutual repulsion of the two magnets when the driving portion 511 stops operating.

It will be appreciated that the particular type of cleaning apparatus 100 is not limited and may be a floor washer, sweeper, or the like.
