Referring to fig. 1, in an embodiment of the present application, a cleaning device 100 is provided, which includes a housing (not shown), a rolling brush mechanism 30 and a driving mechanism 50, wherein the housing has a cleaning opening, the rolling brush mechanism 30 is disposed in the housing in a manner that the rolling brush mechanism 30 corresponds to the cleaning opening, and the rolling brush mechanism 30 that descends to the cleaning opening can be used for cleaning the floor. The driving mechanism 50 is disposed in the housing and can be in transmission connection with the rolling brush mechanism 30, and is used for driving the rolling brush mechanism 30 to swing up and down in the housing in a direction away from and close to the cleaning opening. Wherein the cleaning opening is an opening for exposing the roller brush mechanism 30, through which the cleaning device 100 allows debris on the floor to be cleaned by the roller brush mechanism 30.

Therefore, the dust box can be prevented from being wetted by the large beach water on the ground to generate peculiar smell, and the cleaning range is not limited.

In addition, the rolling brush mechanism 30 is arranged in the shell in a lifting manner, and when the cleaning device 100 encounters an obstacle in the walking process, the rolling brush mechanism 30 can be adaptively lifted under the action of the obstacle, so that the cleaning device 100 can walk more smoothly.

Referring to fig. 2-4, in some embodiments, the driving mechanism 50 has a transmission state and an avoidance state, and in the transmission state, the driving mechanism 50 is in transmission connection with the rolling brush mechanism 30 and drives the rolling brush mechanism 30 to lift; for example, when a large beach water stain is encountered, the driving mechanism 50 is switched to a transmission state to drive the rolling brush mechanism 30 to lift, so that the rolling brush mechanism 30 is prevented from being contacted with the water stain, and the dust box is prevented from being wetted. In the avoidance state, the driving mechanism 50 is separated from the roller brush mechanism 30; for example, when the cleaning mechanism passes over a large beach water spot, the driving mechanism 50 is switched to an avoiding state, so that the driving mechanism 50 is separated from the rolling brush mechanism 30, and the rolling brush mechanism 30 cannot collide with the driving mechanism 50 when encountering obstacle to adaptively lift, thereby preventing noise.

In some embodiments, the driving mechanism 50 includes a driving member 52 and a transmission assembly 54, and the driving member 52 drives the transmission assembly 54 to swing in a direction approaching and moving away from the cleaning opening, and drives the rolling brush mechanism 30 to lift. Thus, when the driving member 52 works, the driving assembly 54 is driven to swing in a direction approaching to and away from the cleaning opening, and then the rolling brush mechanism 30 is driven to approach to and away from the cleaning opening through the swinging driving assembly 54, so as to control the rolling brush mechanism 30 to lift.

Further, the transmission assembly 54 has a supporting surface 541 capable of abutting against the rolling brush mechanism 30, and when the transmission assembly 54 swings under the driving of the driving member 52, the supporting surface 541 moves in a direction approaching and separating from the cleaning opening, and remains parallel to the plane in which the cleaning opening is located. The cleaning device 100 is operated with the cleaning opening in the housing facing the floor and maintaining a horizontal orientation parallel to the floor to allow debris on the floor to be cleaned by the roller brush at the cleaning opening, wherein the plane of the cleaning opening is the horizontal plane of the cleaning device 100 when placed on the floor.

In this way, the supporting surface 541 of the transmission component 54 is matched with the rolling brush mechanism 30 to drive the rolling brush mechanism 30 to lift, and the supporting surface 541 of the transmission component 54 is always kept parallel to the plane where the cleaning opening is located in the driving process, so that the rolling brush mechanism 30 supported by the transmission component 54 is kept horizontal, the rolling brush mechanism 30 cannot incline in the lifting process, and the rolling brush mechanism 30 is prevented from contacting with water stains on the ground due to inclination.

When the first free end 545 and the second free end 548 are swung in synchronization in a direction approaching the cleaning opening, the driving swing arm 542 and the driven swing arm 546 are moved away from each other, and the supporting surface 541 formed by the plane in which the first free end 545 and the second free end 548 are located gradually approaches the cleaning opening, allowing the roll brush mechanism 30 supported by the first free end 545 and the second free end 548 to descend.

In addition, at the initial stage of the swing of the first free end 545 and the second free end 548 towards the direction approaching the cleaning opening, the driving mechanism 50 is in a transmission state, the rolling brush mechanism 30 is allowed to synchronously descend until the rolling brush mechanism 30 descends to the extreme limit position and is blocked by the extreme limit position to keep static, the first free end 545 and the second free end 548 can continue to swing towards the direction approaching the cleaning opening, the driving mechanism 50 is switched to an avoidance state, at this time, the first free end 545 and the second free end 548 are separated from the rolling brush mechanism 30 which is static, and further the rolling brush mechanism 30 is prevented from colliding with the first free end 545 or the second free end 548 when floating under the action of external obstacles, and collision noise is prevented.
