The term "and/or" used herein includes any and all combinations of one or more related listed items.

The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

As shown in Fig. 1-2, an embodiment involves a vacuum cleaner 1, which has a cleaning device 10. The cleaning device 10 includes a shell 100 and a cleaning component 200 having a cleaning position. The cleaning component 200 is rotatably disposed on the shell 100. The cleaning component 200 includes a first cleaning member 210 and a second cleaning member 220 arranged in parallel with the first cleaning member 210. The cleaning component 200 is operably rotatable so that the first cleaning member 210 and the second cleaning member 220 can be selectively moved to the cleaning position.

As shown in FIG2 , specifically, the first cleaning member 210 and the second cleaning member 220 are both roller brushes, and the cleaning assembly 200 further includes a bracket 230 having two opposite sides, and the first cleaning member 210 and the second cleaning member 220 are respectively arranged on both sides of the bracket 230, and the first cleaning member 210 and the second cleaning member 220 are arranged in parallel. The cleaning position is located at the lower side of the cleaning assembly 200, and when the first cleaning member 210 moves to the cleaning position, the first cleaning member 210 can be used to clean the floor, and the second cleaning member 220 serves as a spare cleaning member, and when the second cleaning member 220 moves to the cleaning position, the second cleaning member 220 can be used to clean the floor, and the first cleaning member 210 serves as a spare cleaning member.

First, the cleaning device 10 is described. Before the cleaning member is replaced, it is assumed that the first cleaning member 210 is located at the cleaning position for cleaning the floor, and the second cleaning member 220 is a spare cleaning member. When the cleaning member that can be used to clean the floor needs to be replaced from the first cleaning member 210 to the second cleaning member 220, it is only necessary to operate the cleaning assembly 200, so that the cleaning assembly 200 rotates a certain angle, and the second cleaning member 220 is moved to the cleaning position, which is easy to operate.

As shown in Figures 3 and 5, in one embodiment, the cleaning device 10 also includes a switching mechanism arranged on the shell 100, the shell 100 includes a blocking body 110 arranged opposite to the cleaning component 200, the switching mechanism is rotatably connected to the cleaning component 200, and the switching mechanism is used to drive the cleaning component 200 away from the blocking body 110, so that a movable space for the cleaning component 200 to rotate 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, and is used to prevent dirt and other stains from entering the housing 100. When the cleaning component 200 is in the working position (i.e., the position of the cleaning component in Figures 3 and 4), the cleaning component 200 is close to the blocking body 110, and the blocking body 110 will hinder the rotation of the cleaning component 200. By switching the components to drive the cleaning component 200 away from the blocking body 110, the distance between the cleaning component 200 and the blocking body 110 can be increased, so that there is a movable space between the cleaning component 200 and the blocking body 110 for the cleaning component 200 to rotate (as shown in Figures 5 and 6), so that the blocking body 110 can be prevented from hindering the rotation of the cleaning component 200.

As shown in Fig. 3 and Fig. 5, further, the switching mechanism 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 assembly transmission-connected to the first guide member 310, the operating member 300 is transmission-connected to the first transmission assembly, and the operating member 300 is used to drive the first guide member 310 to move through the first transmission assembly, so that the cleaning assembly 200 is close to or away 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 connected to the first guide member 310.

As shown in Fig. 3, Fig. 5 and Fig. 7, specifically, a first rotating shaft 231 is provided on the bracket 230 of the cleaning assembly 200, a first mounting hole is provided on the first guide member 310, the first rotating shaft 231 is penetrated in the first mounting hole, and the cleaning assembly 200 is rotatably connected with the first guide member 310 via the first rotating shaft 231. The operating member 300 can drive the first guide member 310 to move in a first direction through the first transmission assembly, and can also 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 Figures 3 and 5, more specifically, the first transmission assembly includes a first elastic pushing member 320 and a first traction member 330. The first elastic pushing member 320 is arranged on the shell 100 and abuts against the first guide member 310. One end of the first traction member 330 is connected to the first guide member 310, and the other end is connected to the operating member 300.

Among them, the first elastic pushing member 320 is used to apply a thrust to the first guide member 310 so that the first guide member 310 has a tendency to move along the first direction, so that the cleaning component 200 has a tendency to move away from the blocking body 110; the operating member 300 is used to apply a pulling force to the first guide member 310 through the first traction member 330, so that the first guide member 310 has a tendency to move along the second direction, so that the cleaning component 200 has a tendency to move toward the blocking body 110.

It can be understood that the first elastic push member 320 is used to apply a thrust to the first guide member 310, and the operating member 300 is used to apply a pulling force to the first guide member 310 through the first traction member 330. The difference between the thrust and the pulling force received by the first guide member 310 determines the moving direction of the first guide member 310. When the thrust received by the first guide member 310 is greater than the pulling force, the first guide member 310 moves in the first direction to move the cleaning assembly 200 away from the blocking body 110. When the thrust received by the first guide member 310 is less than the pulling force, the first guide member 310 moves in the second direction to move the cleaning assembly 200 toward the blocking body 110. When the thrust received by 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 member is replaced (as shown in FIG. 3 ), and when the cleaning assembly 200 is in the working position, the first elastic pushing member 320 is in a compressed state, and the tension and thrust on the first guide member 310 are balanced; when the operating member 300 is operated so that the tension on the first guide member 310 is less than the thrust, 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 moves away from the blocking body 110, 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 ). When the cleaning component 200 is at a certain distance from the blocking body 110 and there is a movable space between the cleaning component 200 and the blocking body 110 for the cleaning component 200 to rotate, the cleaning component 200 can be manually rotated to complete the operation of replacing the cleaning component; when the cleaning component 200 completes the operation of replacing the cleaning component, the operating member 300 can be operated so that the pulling force on the first guide member 310 is greater than the pushing force, so that the first guide member 310 moves along the second direction, so that the cleaning component 200 moves toward the blocking body 110 and returns to the working position.

Optionally, the first elastic pushing member 320 may be a spring, a spring sheet or elastic rubber.

As shown in FIG5 , in one embodiment, the housing 100 is provided with a first abutting portion 121, the first guide member 310 is provided with a second abutting portion 3111 spaced apart from the first abutting portion 121, and both ends of the first elastic push member 320 are respectively abutted against the first abutting portion 121 and the second abutting portion 3111. In this way, the first elastic push member 320 can be installed and can apply a thrust to the first guide member 310.

Specifically, the second supporting portion 3111 and the first supporting portion 121 are arranged relative to each other at intervals along the first direction, the first elastic pushing member 320 is arranged between the first supporting portion 121 and the second supporting portion 3111, and the two ends of the first elastic pushing member 320 are respectively abutted against the first supporting portion 121 and the second supporting portion 3111, and the first elastic pushing member 320 can provide a thrust to move the first guide member 310 along the first direction.

As shown in Fig. 5 and Fig. 7, the first guide member 310 further includes a first limiting column 312, and the first elastic pushing member 320 is a spring, and the first elastic pushing member 320 is sleeved on the first limiting column 312. In this way, the first elastic pushing member 320 can be limited, and the second elastic pushing member 360 is prevented from bending along its axial direction when being compressed, thereby improving stability.

As shown in Figures 5 and 7, specifically, the first guide member 310 includes a first guide portion 311 rotatably connected to the cleaning assembly 200, and a first limiting column 312 connected to the first guide portion 311, the first guide portion 311 is provided with a second supporting portion 3111 at one end close to the first limiting column 312, the first supporting portion 121 is provided with a through hole, the first elastic pushing member 320 is arranged between the second supporting portion and the first supporting portion, the first limiting column 312 passes through the first elastic pushing member 320 and the through hole, and is connected to the first traction member 330.

As shown in Fig. 5 and Fig. 7, further, the housing 100 is further provided with a first guide groove 120, and the first guide member 310 is guided and matched with the first guide groove 120. The first guide groove 120 is used to guide the first guide member 310 to move along the first direction or the second direction, so as to avoid deviation of the moving path of the first guide member 310 and improve the stability of the device.

Specifically, the guide path of the first guide groove 120 extends along the first direction, the first guide member 310 slides with the groove wall of the first guide groove 120, and the groove wall of the first guide groove 120 guides the moving direction of the first guide member 310, thereby guiding the first guide member 310 to move along the first direction or the second direction.

As shown in Fig. 3 and Fig. 5, in one embodiment, the cleaning device 10 further includes a first pulley 340, which is disposed on the housing 100, and the first traction member 330 is a flexible traction member, which is wound around the first pulley 340. The first pulley 340 is used to provide tension to the first traction member 330, so that the first traction member 330 is always in a stretched state, thereby ensuring the operating accuracy of the operating member 300 on the first traction member 330.

The first traction member 330 may be a flexible connection member such as a soft rope or a chain.

Specifically, the first pulley 340 is set on the shell 100 by screws, one end of the first traction member 330 is connected to the first guide member 310, and the other end is connected to the operating member 300 after passing through the first pulley 340. The position of the joint between the operating member 300 and the first traction member 330 can be changed by the operating member 300, so that the position of the first guide member 310 is changed under the joint action of the first traction member 330 and the first elastic pushing member 320.

As shown in Fig. 3, Fig. 5 and Fig. 7, further, the operating member 300 is a knob rotatably disposed on the housing 100. When the operating member 300 rotates in the third direction, it is used to pull the first guide member 310 to move in the second direction through the first traction member 330. When the operating member 300 rotates in a fourth direction opposite to the third direction, the first elastic push member 320 is used to push the second guide member 350 to move in the first direction. The moving direction of the first guide member 310 is changed by rotating the operating member 300, which is convenient for operation.

Specifically, the rotation of the operating member 300 along the third direction refers to the rotation of the operating member 300 in the clockwise direction, and the rotation of the operating member 300 along the fourth direction refers to the rotation of the operating member 300 in the counterclockwise direction. The first traction member 330 is fixedly connected to the operating member 300, and the operating member 300 can change the position of the joint between the operating member 300 and the first traction member 330 by rotating, so that the position of the first guide member 310 is changed under the joint action of the first traction member 330 and the first elastic pushing member 320.

As shown in Figures 7, 9 and 10, in one embodiment, a mounting seat 140 is also provided on the shell 100, the mounting seat 140 is provided with a first limiting groove 142, and the operating member 300 is provided with a limiting portion 303, and the limiting portion 303 is used to position and cooperate with the first limiting groove 142 when the cleaning component 200 is in the first position.

Among them, the first position refers to the cleaning component 200 being in the working position (the position of the cleaning component 200 in Figure 3). When the cleaning component 200 is in the first position, the limiting portion 303 sinks into the first limiting groove 142 to prevent the operating member 300 from rotating under the action of the first elastic pushing member 320, thereby causing the position of the cleaning component 200 to be unstable.

As shown in FIG. 7 , FIG. 9 and FIG. 10 , further, the mounting seat 140 is further provided with a second limiting groove 143 , and the limiting portion 303 is used for positioning and cooperating with the second limiting groove 143 when the cleaning assembly 200 is in the second position.

The operating member 300 is also used to drive the second guide member 350 to move through the second transmission assembly to move the cleaning assembly 200 closer to or away from the blocking body 110.

The first guide member 310 and the second guide member 350 are respectively connected to the two ends of the cleaning component 200, which is beneficial to improving the stability of the transmission unit driving the cleaning component 200 to move. The user can simultaneously change the positions of the first guide member 310 and the second guide member 350 by operating the operating member 300, thereby changing the position of the cleaning component 200.

As shown in Fig. 7 and Fig. 8, specifically, one of the brackets 230 of the cleaning assembly 200 is provided with a first rotating shaft 231, and the other end is provided with a second rotating shaft, the first guide member 310 is provided with a first mounting hole, the second guide member 350 is provided with a second mounting hole 3512, the first rotating shaft 231 is inserted into the first mounting hole, the cleaning assembly 200 and the first guide member 310 are rotationally connected through the first rotating shaft 231, the second rotating shaft is inserted into the second mounting hole 3512, and the cleaning assembly 200 and the second guide member 350 are rotationally connected through the second rotating shaft. The operating member 300 can drive the first guide member 310 to move in the first direction through the first transmission assembly, and can also drive the second guide member 350 to move in the fifth direction through the second transmission assembly; and the operating member 300 can drive the first guide member 310 to move in the second direction opposite to the first direction through the first transmission assembly, and can also drive the second guide member 350 to move in the sixth direction opposite to the fifth direction through the second transmission assembly. When the first guide member 310 moves along the first direction and the second guide member 350 moves along the fifth direction, the first guide member 310 and the second guide member 350 drive the cleaning component 200 to move away from the blocking body 110. When the first guide member 310 moves along the second direction and the second guide member 350 moves along the sixth direction, the first guide member 310 and the second guide member 350 drive the cleaning component 200 to move toward the blocking body 110.

One end of the second traction member 370 is connected to the second guide member 350, and the other end is connected to the operating member 300.

Among them, the second elastic pushing member 360 is used to apply a thrust to the second guide member 350 so that the second guide member 350 has a tendency to move along the fifth direction, so that the cleaning component 200 has a tendency to move away from the blocking body 110; the operating member 300 is used to apply a pulling force to the second guide member 350 through the second traction member 370, so that the second guide member 350 has a tendency to move along the sixth direction opposite to the fifth direction, so that the cleaning component 200 has a tendency to move toward the blocking body 110.

It can be understood that the second elastic push member 360 is used to apply a thrust to the second guide member 350, and the operating member 300 is used to apply a pulling force to the second guide member 350 through the second traction member 370. The difference between the thrust and the pulling force received by the second guide member 350 determines the moving direction of the second guide member 350. When the thrust received by the second guide member 350 is greater than the pulling force, the second guide member 350 moves in the fifth direction to move the cleaning assembly 200 away from the blocking body 110. When the thrust received by the second guide member 350 is less than the pulling force, the second guide member 350 moves in the sixth direction to move the cleaning assembly 200 toward the blocking body 110. When the thrust received by the second guide member 350 is equal to the pulling force, the position of the second guide member 350 does not change.

Before the cleaning member is replaced and the cleaning assembly 200 is in the working position (as shown in FIG. 3 ), the second elastic pushing member 360 is in a compressed state, and the pulling force on the second guide member 350 is balanced with the pushing force; when the operating member 300 is operated so that the pulling force on the second guide member 350 is less than the pushing force, the second elastic pushing member 360 extends and pushes the second guide member 350 to move along the fifth 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 away from the blocking body 110, the second elastic pushing member 360 extends and pushes the second guide member 350 to move along the fifth direction (as shown in FIG. 5 ). When the cleaning component 200 is at a certain distance from the blocking body 110 and there is a movable space between the cleaning component 200 and the blocking body 110 for the cleaning component 200 to rotate, the cleaning component 200 can be manually rotated to complete the operation of replacing the cleaning component; when the cleaning component 200 completes the operation of replacing the cleaning component, the operating member 300 can be operated so that the pulling force on the second guide member 350 is greater than the pushing force, so that the second guide member 350 moves along the sixth direction, so that the cleaning component 200 moves toward the blocking body 110 and returns to the working position.
