As shown in fig. 1-2, an embodiment relates to a dust collector 1, the dust collector 1 has a cleaning device 10, the cleaning device 10 includes a housing 100, and a cleaning assembly 200 having a cleaning position, the cleaning assembly 200 is rotatably disposed on the housing 100, the cleaning assembly 200 includes a first cleaning member 210, and a second cleaning member 220 disposed parallel to the first cleaning member 210, and the cleaning assembly 200 is operable to rotate so that the first cleaning member 210 and the second cleaning member 220 can be selectively moved to the cleaning position.

As shown in fig. 2, specifically, the first cleaning member 210 and the second cleaning member 220 are both roller brushes, the cleaning assembly 200 further includes a bracket 230 having opposite sides, the first cleaning member 210 and the second cleaning member 220 are disposed on the opposite sides of the bracket 230, and the first cleaning member 210 and the second cleaning member 220 are disposed in parallel. The cleaning position is located at the lower side of the cleaning assembly 200, the first cleaning member 210 may be used to clean the floor when the first cleaning member 210 is moved to the cleaning position, the second cleaning member 220 may be used as a spare cleaning member, and the second cleaning member 220 may be used to clean the floor when the second cleaning member 220 is moved to the cleaning position, and the first cleaning member 210 may be used as a spare cleaning member.

First, the cleaning apparatus 10 will be described, assuming that the first cleaning member 210 is located at the cleaning position for cleaning the floor before the cleaning members have not been replaced, and the second cleaning member 220 is a spare cleaning member. When the cleaning member for cleaning floor is required to be replaced from the first cleaning member 210 to the second cleaning member 220, the cleaning assembly 200 is only required to be operated, so that the cleaning assembly 200 is rotated by a certain angle, and the second cleaning member 220 assembly 200 is moved to the cleaning position, and the operation is convenient.

As shown in fig. 3 and 5, in one embodiment, the cleaning apparatus 10 further includes a switching mechanism disposed on the housing 100, the housing 100 includes a blocking body 110 disposed opposite to the cleaning component 200 at a distance, the switching mechanism is rotatably connected to the cleaning component 200, and the switching mechanism is used for driving the cleaning component 200 away from the blocking body 110, so that a movable space for rotating the cleaning component 200 is formed between the cleaning component 200 and the blocking body 110.

The blocking body 110 is a baffle at the end of the housing 100, the blocking body 110 is used for preventing dirt such as dust from entering the housing 100, and when the cleaning assembly 200 is in the working position (i.e. the position of the cleaning assembly in fig. 3 and 4), the cleaning assembly 200 is close to the blocking body 110, and the blocking body 110 prevents the cleaning assembly 200 from rotating. The switching component drives the cleaning component 200 to be far away from the blocking body 110, so that the distance between the cleaning component 200 and the blocking body 110 can be increased, and a movable space (as shown in fig. 5 and 6) for the cleaning component 200 to rotate is formed between the cleaning component 200 and the blocking body 110, so that the blocking body 110 can be prevented from blocking the cleaning component 200 to rotate.

As shown in fig. 3 and 5, further, the switching mechanism includes an operation member 300 and a transmission unit, the transmission unit includes a first guide member 310 rotatably connected to the cleaning assembly 200, and a first transmission assembly drivingly connected to the first guide member 310, the operation member 300 is drivingly connected to the first transmission assembly, and the operation member 300 is configured to drive the first guide member 310 to move through the first transmission assembly so as to make the cleaning assembly 200 approach or separate from the blocking body 110. The user can change the position of the first guide 310 by operating the operating member 300, thereby changing the position of the cleaning assembly 200 connected to the first guide 310.

As shown in fig. 3, 5 and 7, specifically, the support 230 of the cleaning assembly 200 is provided with a first rotating shaft 231, the first guide member 310 is provided with a first mounting hole, the first rotating shaft 231 is inserted into the first mounting hole, and the cleaning assembly 200 is rotatably connected with the first guide member 310 through the first rotating shaft 231. The operation member 300 may drive the first guide member 310 to move in a first direction through the first transmission assembly, or drive the first guide member 310 to move in a second direction opposite to the first direction, when the first guide member 310 moves in the first direction, the first guide member 310 drives the cleaning assembly 200 to move away from the blocking body 110, and when the first guide member 310 moves in the second direction, the first guide member 310 drives the cleaning assembly 200 to move toward the blocking body 110.

As shown in fig. 3 and 5, more specifically, the first transmission assembly includes a first elastic pushing member 320 and a first traction member 330, where the first elastic pushing member 320 is disposed on the housing 100 and abuts against the first guiding member 310, and one end of the first traction member 330 is connected to the first guiding member 310, and the other end is connected to the operating member 300.

Wherein the first elastic pushing member 320 is configured to apply a pushing force to the first guide member 310, such that the first guide member 310 has a tendency to move in a first direction, such that the cleaning assembly 200 has a tendency to move away from the blocking body 110; the operating member 300 is configured to apply a pulling force to the first guide member 310 through the first pulling member 330 such that the first guide member 310 has a tendency to move in the second direction such that the cleaning assembly 200 has a tendency to move toward the blocking body 110.

It can be appreciated that the first elastic pushing member 320 is configured to apply a pushing force to the first guiding member 310, the operating member 300 is configured to apply a pulling force to the first guiding member 310 through the first traction member 330, and a difference between the pushing force and the pulling force applied to the first guiding member 310 determines a moving direction of the first guiding member 310. When the pushing force applied to the first guide member 310 is greater than the pulling force, the first guide member 310 moves in a first direction to move the cleaning assembly 200 away from the blocking body 110, when the pushing force applied to the first guide member 310 is less than the pulling force, the first guide member 310 moves in a second direction to move the cleaning assembly 200 toward the blocking body 110, and when the pushing force applied to the first guide member 310 is equal to the pulling force, the position of the first guide member 310 does not change.

Before the cleaning element is replaced (as shown in fig. 3), and when the cleaning assembly 200 is in the working position, the first elastic pushing element 320 is in a compressed state, and the tensile force and the thrust force applied by the first guiding element 310 are balanced; when the operating member 300 is operated such that the pulling force exerted by the first guide member 310 is smaller than the pushing force, the first elastic pushing member 320 extends and pushes the first guide member 310 to move in the first direction (as shown in fig. 5), so that the cleaning assembly 200 moves away from the blocking body 110; when the cleaning assembly 200 is at a certain distance from the blocking body 110, and a movable space for the cleaning assembly 200 to rotate is formed between the cleaning assembly 200 and the blocking body 110, the cleaning assembly 200 can be manually rotated at this time, so that the cleaning member replacement operation is completed; when the cleaning assembly 200 completes the cleaning member replacement operation, the operation member 300 may be operated such that the first guide member 310 receives a greater pulling force than the pushing force, thereby moving the first guide member 310 in the second direction, so that the cleaning assembly 200 moves toward the blocking body 110 and returns to the working position.

Alternatively, the first elastic pushing member 320 may be a spring, a shrapnel, or elastic rubber.
