As shown in fig. 1-2, an embodiment of the present invention relates to a vacuum cleaner 1, the vacuum cleaner 1 includes a cleaning apparatus 10, the cleaning apparatus 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 juxtaposed 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 two opposite sides, the first cleaning member 210 and the second cleaning member 220 are respectively disposed on two 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 can be used to clean the floor surface when the first cleaning member 210 is moved to the cleaning position, the second cleaning member 220 serves as a spare cleaning member, the second cleaning member 220 can be used to clean the floor surface when the second cleaning member 220 is moved to the cleaning position, and the first cleaning member 210 serves as a spare cleaning member.

the cleaning device 10 will first be described assuming that the first cleaning member 210 is in the cleaning position for cleaning the floor surface and the second cleaning member 220 is a spare cleaning member before the cleaning members have not been replaced. When the cleaning member used for cleaning the floor is required to be replaced from the first cleaning member 210 to the second cleaning member 220, only the cleaning assembly 200 is required to be operated, so that the cleaning assembly 200 rotates by a certain angle, and the second cleaning member 220 assembly 200 is required to be 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 assembly 200 at a distance, the switching mechanism is rotatably connected to the cleaning assembly 200, and the switching mechanism is configured to drive the cleaning assembly 200 away from the blocking body 110, so that a movable space for the cleaning assembly 200 to rotate is formed between the cleaning assembly 200 and the blocking body 110.

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

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

as shown in fig. 3, 5, and 7, specifically, the bracket 230 of the cleaning assembly 200 is provided with a first rotating shaft 231, the first guide 310 is provided with a first mounting hole, the first rotating shaft 231 penetrates the first mounting hole, and the cleaning assembly 200 is rotatably connected to the first guide 310 through the first rotating shaft 231. The operating element 300 may drive the first guiding element 310 to move along a first direction through the first transmission assembly, and may also drive the first guiding element 310 to move along a second direction opposite to the first direction, when the first guiding element 310 moves along the first direction, the first guiding element 310 drives the cleaning element 200 to move away from the blocking body 110, and when the first guiding element 310 moves along the second direction, the first guiding element 310 drives the cleaning element 200 to move towards 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 pulling member 330, the first elastic pushing member 320 is disposed on the housing 100 and abuts against the first guiding member 310, one end of the first pulling 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 used for applying a pushing force to the first guiding member 310 so that the first guiding member 310 has a tendency to move along the first direction, so that the cleaning assembly 200 has a tendency to move away from the blocking body 110; the manipulating member 300 is used to apply a pulling force to the first guide 310 by the first pulling member 330 to make the first guide 310 have a tendency to move in the second direction, so that the cleaning assembly 200 has a tendency to move toward the blocking body 110.

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

Before the cleaning elements are not replaced (as shown in fig. 3), and the cleaning assembly 200 is in the working position, the first elastic pushing element 320 is in a compressed state, and the pulling force and the pushing force on the first guiding element 310 are balanced; when the operating element 300 is operated, so that the pulling force applied to the first guiding element 310 is smaller than the pushing force, the first elastic pushing element 320 extends and pushes the first guiding element 310 to move along a 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 barrier 110 and a movable space for the cleaning assembly 200 to rotate is formed between the cleaning assembly 200 and the barrier 110, the cleaning assembly 200 can be manually rotated to complete the operation of replacing the cleaning member; after the cleaning assembly 200 completes the cleaning member replacement operation, the operation member 300 may be operated such that the pulling force applied to the first guiding member 310 is greater than the pushing force, so that the first guiding member 310 moves in the second direction, and 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 leaf spring, an elastic rubber, or the like.
