It is to be understood that the above definitions are merely provided to facilitate understanding of the relative position relationship of the structural members in the rolling brush mechanism 100, and should not be construed as limiting the present application.

As shown in fig. 1 and 7, in the embodiment, a rolling brush mechanism 100 is provided, which can be used in a surface cleaning apparatus to remove dirt on a surface 300 to be cleaned, so as to clean the surface 300 to be cleaned.

The surface cleaning device can be one of a sweeper, a floor washer, a wall cleaning robot, a table top cleaning robot, a window cleaning robot and the like. The surface 300 to be cleaned may be one or more of a floor, a table, a wall, a window, etc.

As shown in fig. 1 and 2, the roll brush mechanism 100 includes a housing 10, a liner housing 20, and a roll brush 30.

The housing 10 may include a housing main body 11 and a first connecting portion 12, and the first connecting portion 12 may be fixedly connected to one side of the housing main body 11. In some embodiments, the housing main body 11 and the first connection portion 12 may be provided as one body.

In other embodiments, the housing body 11 and the first connecting portion 12 may be fixedly connected by screws, bonding, clamping, or the like.

Referring to fig. 3, 7 and 8 together, the liner case 20 may include a liner case body 21 and a second connection portion 22. Wherein the liner case body 21 is accommodated in the case main body 11. Meanwhile, a floating gap 80 is provided between the liner case body 21 and the outer case main body 11.

In the embodiment, the second connection portion 22 is fixedly connected to the liner shell body 21 on a side close to the first connection portion 12. For example, the second connection portion 22 and the lining shell body 21 may be fixedly connected by way of integral molding, screw connection, adhesion, clamping, welding, or the like. The second connecting portion 22 is rotatably connected to the first connecting portion 12 to achieve the connection between the liner case 20 and the outer case 10.

Of course, in other embodiments, the second connection portion 22 and the lining shell body 21 may be movably connected by a rotation connection or the like.

It can be understood that the second connecting portion 22 rotates relative to the first connecting portion 12 to drive the lining shell body 21 to move relative to the housing main body 11, wherein a floating gap between the lining shell body 21 and the housing main body 11 can provide a space for the lining shell body 21 to move relative to the housing main body 11, that is, the lining shell body 21 is installed in a floating manner relative to the housing main body 11.

In some embodiments, when the second connection portion 22 rotates relative to the first connection portion 12, the rotation axis of the second connection portion 22 may be parallel to the length direction of the rolling brush mechanism 100.

The roller brush 30 is rotatably mounted on the side of the lining shell body 21 away from the housing main body 11, i.e., the roller brush 30 can smoothly rotate with respect to the lining shell body 21. In one embodiment, the roller brush 30 can provide cleaning operation for the surface 300 to be cleaned to remove the dirt on the surface 300 to be cleaned.

As shown in fig. 1, 2 and 6, in the axial direction of the roll brush 30, the length n of the second connecting portion 22 and the length m of the lining shell body 21 satisfy,

here, the axial direction of the roll brush 30 may refer to an extending direction of the axis L of the roll brush 30 itself. In some embodiments, the axial direction of the rolling brush 30 may be parallel to the length direction of the rolling brush mechanism 100. In the embodiment, the roller brush 30 is rotatable about its own axis L when rotated relative to the lining shell body 21.

Referring to fig. 7 and 8, it can be understood that the lining shell body 21 can drive the rolling brush 30 to float synchronously when floating relative to the housing main body 11.

When the rolling brush mechanism 100 encounters an obstacle 400 on the surface 300 to be cleaned, the rolling brush 30 may move in a direction away from the surface 300 to be cleaned under the urging of the obstacle 400. Meanwhile, the roll brush 30 may push the lining shell body 21 to move synchronously even if the lining shell 20 floats with respect to the outer shell 10. The length of the second connecting portion 22 is 1/4 to 1/2 of the length of the lining shell body 21, so that when the second connecting portion 22 rotates relative to the first connecting portion 12, the second connecting portion 22 can provide stable and reliable support for the lining shell body 21, so that the rolling brush 30 smoothly crosses over the obstacle 400 under the pulling of the lining shell 20, that is, the rolling brush mechanism 100 can smoothly cross over the obstacle, and the problem that the rolling brush 30 cannot cross over the obstacle 400 due to shaking, tilting and the like is avoided.

Therefore, the rolling brush mechanism 100 provided by the application can improve the reliability when the rolling brush mechanism crosses the obstacle 400, and ensure the obstacle crossing capability of the surface cleaning equipment.

Further, as shown in fig. 1 and 3, in some embodiments, the inside of the housing main body 11 may be a hollow structure, and forms a first receiving cavity 1101 to provide a receiving space for the liner housing body 21. In an embodiment, the liner housing body 21 may be disposed in the first accommodation chamber 1101. In the height direction of the rolling brush mechanism 100, a gap may be left between the liner case body 21 and the inner wall of the first accommodation chamber 1101, that is, a floating gap 80 is formed, to provide a space for floating of the liner case body 21 relative to the housing main body 11.

In an embodiment, the lining shell body 21 may also be a hollow structure, and the second accommodating cavity 2101 is formed inside the hollow structure. The roller brush 30 may be installed in the second receiving cavity 2101 and rotatably connected to the lining case body 21.

In some embodiments, a first opening structure 1102 communicating with the first accommodating chamber 1101 is formed on one side of the housing main body 11. The first opening structure 1102 may be formed at a side of the housing body 11 away from the floating gap 80. A second opening structure 2102 is formed in one side, close to the first opening structure 1102, of the lining shell body 21, and the second opening structure 2102 is communicated with the second accommodating cavity 2101.

The roller brush 30 may be exposed sequentially through the second and

first opening structures

2102 and 1102 so that the roller brush 30 may contact the surface 300 to be cleaned to provide cleaning work to the surface 300 to be cleaned.

As shown in fig. 3 to 5, in some embodiments, the second connection portion 22 may be a connection plate, i.e., the second connection portion 22 presents a plate-shaped structure. The connection plate may include opposing first and

second sides

2201, 2202, wherein the first side 2201 may be fixedly attached to the liner shell body 21. It is understood that the first side 2201 is connected to a side of the liner housing body 21 away from the second accommodating cavity 2101, and the first side 2201 is connected to a side of the liner housing body 21 close to the first connection portion 12.

In the embodiment, the second side 2202 of the connecting plate is rotatably connected to the first connecting portion 12 by two symmetrical rotating shafts 23. Specifically, along the length direction of the rolling brush mechanism 100, two ends of the connecting plate are respectively and fixedly connected with a rotating shaft 23, and the two rotating shafts 23 are both disposed near the second side 2202 of the connecting plate. One end of the rotating shaft 23 far away from the connecting plate is rotatably connected with the first connecting part 12. In an embodiment, the rotation shaft 23 may be parallel to the axial direction of the roll brush 30.

In other embodiments, the shaft 23 may be rotatably connected to the connecting plate. One end of the rotating shaft 23 far away from the connecting plate can be fixedly connected with the first connecting part 12.

Referring also to fig. 6, in some embodiments, the length of the connecting plate may be 1/3 of the liner housing body 21 along the length of the rolling brush mechanism 100. Of course, in other embodiments, the length of the connecting plate may also be set to 1/4, 5/12, 1/2, etc. of the lining shell body 21 along the length direction of the rolling brush mechanism 100.

As shown in fig. 4 and 5, further, a hollow-out groove 2203 is further formed on the connecting plate, so that the weight of the connecting plate can be reduced, and the material cost of the connecting plate can be reduced. Further, the weight of the roller brush mechanism 100 and the surface cleaning apparatus can be reduced, as well as the production cost. Along the height direction of the rolling brush mechanism 100, the hollow-out groove 2203 may be opened on the side of the connecting plate away from the second opening structure 2102 or on the side of the connecting plate close to the second opening structure 2102.

In the embodiment, a plurality of reinforcing ribs 221 arranged in a staggered manner are further arranged in the hollow-out groove 2203, so that the structural strength of the connecting plate can be enhanced, and the probability of fracture of the connecting plate is reduced. In some embodiments, the plurality of ribs 221 may be arranged in an orthogonal distribution.

Of course, in other embodiments, the plurality of ribs 221 may be non-orthogonally disposed. Or, the plurality of ribs 221 may be distributed in parallel or non-parallel and non-intersecting manner.

As shown in fig. 1 to 3, in some embodiments, the first connecting portion 12 may be a casing structure covering the second connecting portion 22. That is, the second connecting portion 22 is inserted into the first connecting portion 12, two rotating shafts 23 connected to the second connecting portion 22 can be connected to two opposite side walls of the first connecting portion 12, and the rotating shafts 23 are connected to a side of the first connecting portion 12 away from the housing main body 11. It will be appreciated that the side of the second connecting portion 22 facing away from the second opening 2102 is spaced from the inner wall of the first connecting portion 12 to provide clearance for rotation of the second connecting portion 22.

In other embodiments, the second connecting portion 22 may also be a connecting rod structure and may be fixedly connected to the lining shell body 21 by a connecting arm or the like. The second connecting portion 22 has two ends directly rotatably connected to the first connecting portion 12.

As shown in fig. 1 and fig. 4, further, at least one first stopper 111 is disposed around an end of the housing main body 11 close to the first opening structure 1102. The first limiting member 111 extends from the sidewall of the housing body 11 toward the middle of the first opening structure 1102.

For example, in some embodiments, two first stoppers 111 are circumferentially disposed on an end of the housing main body 11 close to the first opening structure 1102, and are located on a side of the housing main body 11 away from the first connecting portion 12. Along the length direction of the rolling brush mechanism 100, two first stoppers 111 are respectively disposed at two ends of the housing main body 11.

Correspondingly, at least one second limiting member 211 is disposed on the liner housing body 21 near one end of the second opening structure 2102 in the circumferential direction. The second retaining member 211 has a sidewall of the housing body 21 protruding and extending away from the second opening 2102. In an embodiment, the number of the second limiting members 211 may be equal to the number of the first limiting members 111, and the second limiting members are disposed opposite to each other.

In an embodiment, the first limiting member 111 and the second limiting member 211 are engaged with each other to prevent the liner housing body 21 from falling off from the housing main body 11, so as to ensure that the liner housing body 21 is always accommodated in the housing main body 11.

In other embodiments, the circumferential direction of the end of the housing main body 11 close to the first opening structure 1102 may be further provided with one, three, five, six, etc. first limiting members 111, and correspondingly, the circumferential direction of the end of the liner shell main body 21 close to the second opening structure 2102 may be provided with an equal number of second limiting members 211. The first limiting member 111 is engaged with the second limiting member 211 to prevent the liner housing body 21 from falling off from the housing main body 11.

As shown in fig. 1 and 4, in some embodiments, the first limiting member 111 and the second limiting member 211 can be both configured as a plate-shaped structure, so as to increase a contact area between the first limiting member 111 and the second limiting member 211, so that the first limiting member 111 provides a stable and reliable support for the second limiting member 211, and further provides a stable and reliable limiting function for the liner shell body 21, and the liner shell body 21 is prevented from falling off from the housing main body 11.

Of course, in other embodiments, the first position-limiting member 111 may also be a rod-shaped structure, an arc-shaped plate structure, etc., and the second position-limiting member 211 may also be a column-shaped structure, an arc-shaped plate structure, etc.

Further, in some embodiments, the elastic member 70 is disposed on one side of the second limiting member 211 close to the first limiting member 111. When the liner housing body 21 floats in the housing main body 11, specifically, when the liner housing body 21 moves from a position far away from the first opening structure 1102 to a position close to the first opening structure 1102 under the action of gravity, the second limiting member 211 will gradually abut against the first limiting member 111 under the driving of the liner housing body 21. The elastic member 70 can prevent the first limiting member 111 and the second limiting member 211 from rigidly colliding, thereby reducing the probability of damage to the first limiting member 111 and the second limiting member 211, avoiding generation of collision abnormal sound, and improving user experience. In an embodiment, the elastic member 70 may be a flexible pad structure such as a silicone pad, a rubber pad, or foam.

In other embodiments, the elastic element 70 may also be a spring, a leaf spring, or the like.

In other embodiments, the elastic element 70 may also be disposed on a side of the first limiting element 111 close to the second limiting element 211. Or, the elastic member 70 is disposed on one side of the first limiting member 111 close to the second limiting member 211 and one side of the second limiting member 211 close to the first limiting member 111.

As shown in fig. 7 and 8, during cleaning of the surface 300 to be cleaned, the side of the drum brush 30 exposed with respect to the second opening structure 2102 and the first opening structure 1102 may be brought into contact with the surface 300 to be cleaned. When the rolling brush mechanism 100 encounters the obstacle 400, the rolling brush 30 may move away from the surface 300 to be cleaned under the pushing action of the obstacle 400, and the lining shell 20 is driven by the rolling brush 30 to float relative to the outer shell 10. After the rolling brush 30 passes over the obstacle 400, the rolling brush 30 and the lining shell 20 can be reset under the action of gravity, that is, the rolling brush 30 and the lining shell 20 can be reset by moving towards the direction close to the surface 300 to be cleaned, and the rolling brush 30 and the lining shell body 21 can be prevented from falling from the housing main body 11 by the matching and limiting of the first limiting piece 111 and the second limiting piece 211.

In some embodiments, when the rolling brush 30 rolls over the obstacle 400, the floating angle α of the liner case 20 and the rolling brush 30 with respect to the surface 300 to be cleaned may be 0 ° < α ≦ 30 °, enhancing the obstacle crossing ability of the rolling brush mechanism 100. For example, the floating angle α of the liner case 20 and the roll brush 30 with respect to the surface 300 to be cleaned may be set to 12 °, 15 °, 19 °, 21 °, etc. It is understood that the floating angle α may refer to a maximum swing angle of the liner case 20 and the roll brush 30 with respect to the surface 300 to be cleaned. The space occupied by the rolling brush mechanism 100 is ensured to be as small as possible, and meanwhile, the rolling brush mechanism 100 has high obstacle crossing capability so as to improve the user experience.

Of course, in other embodiments, the floating angle α of the liner case 20 and the roll brush 30 with respect to the surface 300 to be cleaned may be set to 1 °, 5 °, 8 °, 25 °, 28 °, 30 °, etc.

As shown in fig. 1, 2 and 4, the rolling brush mechanism 100 further includes a driving unit 40 for driving the rolling brush 30 to rotate around its own axis L.

The driving unit 40 may include a driving member 41 and a transmission assembly 42, wherein the driving member 41 may be in transmission connection with one end of the roller brush 30 through the transmission assembly 42, and the roller brush 30 may be driven by the driving member 41 to rotate. In some embodiments, the driving member 41 can be a motor, and the transmission assembly 42 can be a combination of a timing belt and a timing wheel, so as to smoothly transmit the output power of the driving member 41 to the roller brush 30, and avoid the occurrence of the problems of slipping and the like.

In the embodiment, the transmission assembly 42 is disposed in a mounting housing 44 to prevent impurities and the like from entering and interfering with the operation of the transmission assembly 42. The driving member 41 is fixedly installed at a side outside the mounting case 44. It will be appreciated that the output shaft of the driver 41 may extend into the mounting housing 44 to connect with the transmission assembly 42. The shaft core of the roller brush 30 may also extend into the mounting housing 44 and be drivingly connected to the output shaft of the drive assembly 42.

The mounting case 44 may be fixedly mounted to one end of the liner case body 21 in the lengthwise direction of the roll brush mechanism 100. The driving member 41 may be disposed at a side of the mounting shell 44 adjacent to the lining shell body 21. In order to ensure the mounting stability of the driving member 41, a supporting block 212 for supporting the driving member 41 is further protrudingly provided on a side surface of the liner housing body 21 away from the second accommodating chamber 2101. When the lining shell 20 drives the roller brush 30 to float relative to the outer shell 10, the driving unit 40 can be driven to move synchronously, so as to ensure the stability of power transmission between the roller brush 30 and the driving unit 40.

As shown in fig. 2, in some embodiments, the second connection portion 22 may be disposed near an end of the liner housing body 21 where the driving unit 40 is mounted. On one hand, the stability of the lining shell 20 during floating can be ensured, on the other hand, the probability of the lining shell 20 breaking can be reduced, and the service life of the rolling brush mechanism 100 is prolonged.

As shown in fig. 1, in some embodiments, the drive unit 40 further includes a plug connector 43. The plug-in connector 43 is disposed at an end of the driving member 41 away from the mounting shell 44, and is electrically connected to the driving member 41. The plug-in connector 43 facilitates the plug-in electrical connection between the driving member 41 and the main body 200 of the surface cleaning apparatus, thereby saving the wiring space. In some embodiments, the plug connector 43 may be a gold finger, a Universal Serial Bus (USB) connector, or the like.

As shown in fig. 1 and 3, the rolling brush mechanism 100 further includes an air duct 60 for discharging dirt cleaned by the rolling brush 30.

Specifically, one end of the air guiding tube 60 may be communicated with the second accommodating cavity 2101 in the lining shell body 21. Correspondingly, a second air guiding opening 2103 communicated with the second accommodating cavity 2101 is formed in one side, away from the second opening structure 2102, of the lining shell body 21, and one end of the air guiding pipe 60 is connected with the second air guiding opening 2103 in a sealing mode. The end of the housing body 11 away from the first opening structure 1102 is opened with a first air guiding opening 1103 opposite to the second air guiding opening 2103. The end of the air duct 60 away from the second air guiding opening 2103 can be connected to the first air guiding opening 1103 in a sealing manner.

When the rolling brush mechanism 100 is mounted on the main body 200, one end of the air duct 60 near the first air guiding opening 1103 can be sequentially communicated with a dust collecting box (not shown) and a fan (not shown) in the main body 200. Therefore, the blower inside the main body 200 can provide power to convey the dirt cleaned by the roller brush 30 to the dust collecting box inside the main body 200 through the second accommodating chamber 2101 and the air duct 60 in sequence.

In some embodiments, the duct 60 may be a flexible tube such as a silicone tube, a rubber tube, an accordion tube, or the like. Therefore, when the liner 20 floats relative to the outer shell 10, the air guide pipe 60 can be deformed according to the movement of the liner 20, and the air guide pipe 60 can be ensured to be smooth.

As shown in fig. 1 to 3, in some embodiments, the rolling brush mechanism 100 further includes a bottom cover 50, and the bottom cover 50 can be disposed at the second opening 2102 of the liner housing body 21. In an embodiment, the bottom cover 50 and the lining shell body 21 can be detachably connected by a spring buckle, a snap, a lock screw, or the like. An avoiding hole 501 opposite to the roller brush 30 may be formed in the bottom cover 50 so that the roller brush 30 smoothly contacts the surface 300 to be cleaned to provide a cleaning operation for the surface 300 to be cleaned. It can be understood that the avoiding hole 501 may serve as a dust suction port of the rolling brush mechanism 100, and dirt may enter the second accommodating cavity 2101 through the avoiding hole 501.

It can be understood that, during the obstacle crossing process of the rolling brush mechanism 100, the bottom cover 50 may also float synchronously with the lining shell 20, so that the distance between the avoiding hole 501 and the surface 300 to be cleaned, that is, the distance between the dust suction opening and the surface 300 to be cleaned, may be adjusted to ensure the dust suction effect and improve the user experience.

As shown in fig. 1 and fig. 2, further, a plurality of buckles 112 are further disposed on a circumferential direction of an end of the housing main body 11 close to the first opening structure 1102, and the plurality of buckles 112 are used for buckling the main body 200 to achieve a detachable connection between the roller brush mechanism 100 and the main body 200. That is, the entire rolling brush mechanism 100 may be detachable from the main body 200 to facilitate operations such as maintenance, repair, or replacement of the rolling brush mechanism 100. It is understood that the latch 112 may be disposed on a side of the housing body 11 away from the first receiving cavity 1101.

Illustratively, three, four, five, six, eight, etc. snaps 112 may be circumferentially disposed about the housing body 11. Meanwhile, a plurality of the snaps 112 may be uniformly distributed around the circumference of the housing body 11 to ensure the connection reliability of the roll brush mechanism 100 and the main body 200.

Of course, in other embodiments, the plurality of buckles 112 may be distributed non-uniformly around the circumference of the housing body 11.

Embodiments also provide a surface cleaning apparatus that may be used to clean one or more of a floor, wall, table, window, or surface 300 waiting to be cleaned.

The surface cleaning apparatus may include a main body 200 and a rolling brush mechanism 100 provided in the embodiments. Wherein, the rolling brush mechanism 100 is detachably installed at one side of the main body 200. It is understood that the roll brush 30 of the roll brush mechanism 100 may be externally protruded with respect to one side of the main body 200.

When the surface cleaning apparatus is operated, the rolling brush mechanism 100 side of the surface cleaning apparatus can be brought close to the surface 300 to be cleaned, and the rolling brush 30 is brought into contact with the surface 300 to be cleaned, so that the cleaning work can be performed on the surface 300 to be cleaned. When the surface cleaning apparatus encounters an obstacle 400 on the surface 300 to be cleaned, the obstacle 400 can be smoothly crossed without having to re-plan the cleaning route or the like. Correspondingly, the working efficiency of the surface cleaning equipment can be improved, and the user experience is improved.
