Description

Technical Field

[0001] This application relates to the technical field of automatic cleaning equipment, and in particular to a side brush device and an automatic cleaning device. Background Technology

[0002] Automatic cleaning devices, also known as robotic vacuum cleaners, are devices that can automatically clean, freeing people's hands and are very popular with consumers. Generally, automatic cleaning devices are disc-shaped, making it difficult to clean corners, furniture edges, and other hard-to-reach areas. Therefore, automatic cleaning devices are equipped with cleaning devices at the edges, called side brushes. These side brushes effectively sweep debris and dust from hard-to-reach areas such as wall edges and furniture edges into the cleaning range of the automatic cleaning device.

[0003] The side brush device includes a cleaning brush that contacts the surface to be cleaned. A conventional cleaning brush maintains continuous contact with the floor, as exemplified by CN109091072B – a side brush device for a robotic vacuum cleaner. If there are sticky contaminants such as liquid stains, grease, or dust on the floor, these contaminants will adhere to the cleaning brush, causing it to become dirty. When the dirty brush continues to work, it will carry the contaminants back to the previously clean floor, creating secondary pollution. When the device passes over carpets, the cleaning brush will also pull and entangle the carpet fibers, which will damage the carpet and increase the noise and energy consumption of the device during operation.

[0004] To avoid the aforementioned technical problems, the side brush device also includes a lifting mechanism, which can raise the cleaning brush to avoid unnecessary contact. For example, CN118303807A - A side brush lifting device, CN118716976A - Side sweeping lifting device and cleaning equipment, etc., embody the above-mentioned technology.

[0005] To improve the mobility of the equipment, its thickness needs to be minimized, which requires maximizing its structural compactness in the thickness direction. However, since the lifting mechanism needs to move up and down to drive the sweeping brush, a certain amount of lifting space needs to be reserved for the lifting mechanism. This affects the structural compactness of the equipment in the thickness direction, which is detrimental to improving the equipment's passage capacity. Utility Model Content

[0006] The purpose of this application is to overcome the shortcomings of the prior art and provide a side brush device and automatic cleaning device that improves the structural compactness of the device in the thickness direction.

[0007] The objective of this application is achieved through the following technical solution:

[0008] In a first aspect, this application provides a side brush device, comprising:

[0009] Mounting housing;

[0010] A rotating component is rotatably connected to the mounting housing to form a first axis.

[0011] A cleaning brush is connected to the rotating component;

[0012] A transmission component, the first end of which is rotatably connected to the rotating component to form a second axis inclined to the first axis; and

[0013] The actuating element is coaxially arranged with the mounting housing and can rotate relative to it. It is also used to abut against the second end of the transmission element. When rotating relative to the mounting housing, it pushes the transmission element to swing along the rotation plane of the actuating element, so that the rotating element rotates along the first axis and drives the cleaning brush to rise and fall.

[0014] In some embodiments, the cleaning brush is fixedly connected to the rotating member, and the extending direction of the cleaning brush forms an angle with the first axis.

[0015] When the rotating component rotates around the first axis, the entire cleaning brush rotates and rises and falls around the first axis.

[0016] In some embodiments, the cleaning brush includes a mounting arm and a bristle arm. The mounting arm is coaxially arranged and fixedly connected to the rotating member. The bristle arm is connected to the mounting arm and has an included angle with the mounting arm, so that the cleaning brush will flip when the rotating member rotates around the first axis.

[0017] In some embodiments, the side brush device is provided with two limiting surfaces, and the second end of the transmission member is located between the two limiting surfaces. The two limiting surfaces together limit the second end of the transmission member on the rotation plane of the actuating member.

[0018] The actuating member has two spaced-apart abutment surfaces along its circumference, and the second end of the transmission member is located between the two abutment surfaces. Each abutment surface is used to abut against the second end of the transmission member. When the actuating member rotates relative to the mounting housing, one of the abutment surfaces pushes the transmission member to swing along the rotation plane of the actuating member.

[0019] In some embodiments, each of the abutting surfaces is an arc surface, and each of the abutting surfaces protrudes toward the other abutting surface.

[0020] In some embodiments, the transmission member includes a connecting part, a transition part, and a force-receiving part connected in sequence, the connecting part being rotatably connected to the rotating member, and the actuating member being used to abut against the force-receiving part;

[0021] When the actuating member rotates relative to the mounting housing, it pushes the force-receiving part to slide along the rotation plane of the actuating member, causing the transmission member to swing along the rotation plane of the actuating member.

[0022] In some embodiments, the rotating member is provided with a connecting hole, and the connecting part is rotatably connected to the connecting hole.

[0023] In some embodiments, the mounting housing has a rotating area, and the rotating member is located within the rotating area and rotatably connected to the mounting housing.

[0024] In some embodiments, the periphery of the mounting housing is provided with a clearance opening that communicates with the rotating area, and the cleaning brush passes through the clearance opening.

[0025] Secondly, this application provides an automatic cleaning device, including a driving device and a side brush device as described in any of the above embodiments. The driving device is pulsatorically connected to one of the actuating member and the mounting housing, and the driving device is used to cause the actuating member to rotate relative to the mounting housing.

[0026] Compared with the prior art, this application has at least the following advantages:

[0027] 1. When the actuating component rotates relative to the mounting housing, the actuating component pushes the second end of the transmission component. After being pushed by the actuating component, the transmission component swings along the rotation plane of the actuating component. At this time, since the second axis is inclined to the first axis, the transmission component will not only rotate around the second axis, but also drive the rotating component to rotate around the first axis, so as to drive the sweeping brush to switch between the sweeping position and the retracted position.

[0028] 2. The relative rotation between the actuating component and the mounting housing can drive the sweeping brush to switch between the sweeping position and the retracted position. Since the relative rotation between the actuating component and the mounting housing does not involve lifting or lowering, there is no need to reserve lifting or lowering space for the actuating component and the mounting housing. In other words, there is no need to reserve lifting or lowering space for the components that drive the sweeping brush to lift or lower. This makes the automatic cleaning equipment more compact in the thickness direction, which is beneficial to improving the passability of the automatic cleaning equipment.

[0029] 3. The mounting shell and the actuating component are rotatably connected, and the transmission component is rotatably connected to the mounting shell. The actuating component and the transmission component abut against each other, so that the side brush device lifts the cleaning brush through multiple low-pair transmissions. This simplifies the structure of the side brush device, reduces the design, manufacturing and assembly difficulty of the side brush device, and also reduces the wear caused by the transmission. This not only extends the service life of the side brush device, but also improves the working stability of the side brush device. Attached Figure Description

Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0046] Example 1:

[0047] like Figure 1 and Figure 2 As shown, the side brush device 10 provided in this application embodiment includes a mounting shell 100, a rotating component 200, a cleaning brush 300, a transmission component 400, and a toggle component 500.

[0048] The rotating component 200 is rotatably connected to the mounting housing 100 to form a first axis 210, that is, the axis on which the rotating component 200 rotates relative to the mounting housing 100 is the first axis 210.

[0049] The cleaning brush 300 is connected to the rotating component 200. When the rotating component 200 rotates around the first axis 210, it can switch the cleaning brush 300 between a cleaning position and a retracted position. It can be understood that the cleaning brush 300 is in contact with the surface to be cleaned when in the cleaning position, and separates from the surface to be cleaned when in the retracted position. The surface to be cleaned can be a floor, wall, tabletop, or other existing surface that needs cleaning. The floor can be a tile surface, cement surface, carpet, or other existing floor surface.

[0050] The first end of the transmission member 400 is rotatably connected to the rotating member 200 to form a second axis 401 that is inclined to the first axis 210. That is, the axis of rotation of the transmission member 400 relative to the rotating member 200 is the second axis 401, and the second axis 401 is inclined to the first axis 210.

[0051] The actuating member 500 is coaxially arranged with the mounting housing 100, and the actuating member 500 and the mounting housing 100 are rotatable relative to each other. The actuating member 500 is also used to abut against the second end of the transmission member 400. When the actuating member 500 rotates relative to the mounting housing 100, it pushes the second end of the transmission member 400 through the abutting force, thereby pushing the transmission member 400 to swing along the rotation plane of the actuating member 500, causing the rotating member 200 to rotate along the first axis 210 and drive the sweeping brush 300 to rise and fall, that is, to drive the sweeping brush 300 to switch between the sweeping position and the retracted position. Specifically, when the actuating member 500 rotates relative to the mounting housing 100, the actuating member 500 pushes the second end of the transmission member 400. After being pushed by the actuating member 500, the transmission member 400 swings along the rotation plane of the actuating member 500. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 will not only rotate around the second axis 401, but also drive the rotating member 200 to rotate around the first axis 210, so as to drive the cleaning brush 300 to switch between the cleaning position and the retracted position.

[0052] It can be understood that the rotation plane of the toggle member 500 is a plane perpendicular to the rotation center line of the toggle member 500.

[0053] like Figure 2 and Figure 3 As shown, in this embodiment, when the sweeping brush 300 is switched from the sweeping position to the retracted position, the actuating member 500 rotates relative to the mounting shell 100 in direction A, and pushes the second end of the transmission member 400 through the abutment force, causing the transmission member 400 to swing along the rotation plane of the actuating member 500 in direction B. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 not only rotates around the second axis 401 in direction C1, but also drives the rotating member 200 to rotate around the first axis 210 in direction D, so that the sweeping brush 300 is switched from the sweeping position to the retracted position.

[0054] Conversely, such as Figure 4 As shown, when the sweeping brush 300 is switched from the retracted position to the sweeping position, the actuating member 500 rotates relative to the mounting housing 100 in direction a, and pushes the second end of the transmission member 400, causing the transmission member 400 to swing along the rotation plane and direction b of the actuating member 500. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 not only rotates around the second axis 401 in direction C2, but also drives the rotating member 200 to rotate around the first axis 210 in direction d, so that the sweeping brush 300 is switched from the retracted position to the sweeping position.

[0055] It is understandable that direction A is opposite to direction a, direction B is opposite to direction b, direction C1 is opposite to direction C2, and direction D is opposite to direction d.

[0056] When the actuating member 500 rotates relative to the mounting housing 100, the actuating member 500 pushes the second end of the transmission member 400. After being pushed by the actuating member 500, the transmission member 400 swings along the rotation plane of the actuating member 500. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 will not only rotate around the second axis 401, but also drive the rotating member 200 to rotate around the first axis 210, so as to drive the cleaning brush 300 to switch between the cleaning position and the retracted position.

[0057] The relative rotation between the actuating component 500 and the mounting housing 100 can drive the sweeping brush 300 to switch between the sweeping position and the retracted position. Since the relative rotation between the actuating component 500 and the mounting housing 100 does not involve lifting or lowering, there is no need to reserve lifting or lowering space for the actuating component 500 and the mounting housing 100. In other words, there is no need to reserve lifting or lowering space for the components that drive the sweeping brush 300 to lift or lower, which makes the automatic cleaning equipment more compact in the thickness direction, which is beneficial to improving the passability of the automatic cleaning equipment.

[0058] The mounting housing 100 is rotatably connected to the actuating member 500, and the transmission member 400 is rotatably connected to the mounting housing 100. The actuating member 500 abuts against the transmission member 400, so that the side brush device 10 lifts the cleaning brush 300 through multiple low-pair transmissions. This simplifies the structure of the side brush device 10, reduces the design, manufacturing and assembly difficulty of the side brush device 10, and also reduces the wear caused by the transmission. This not only extends the service life of the side brush device 10, but also improves the working stability of the side brush device 10.

[0059] It should be noted that the terms "raise," "lift," "retract," "lower," "descend," and "put down" used in this document, which indicate orientation or positional relationships based on the accompanying drawings, are only for the purpose of clearly describing the embodiments of this application and do not indicate or imply that the structure or component referred to must have a specific orientation or be constructed in a specific orientation. That is, they do not represent the only implementation method and therefore should not be construed as limiting the embodiments of this application. For example, when the surface to be cleaned is the ground, "raise," "lift," and "retract" are all directions of movement away from the ground, while "lower," "descend," and "put down" are all directions of movement closer to the ground; when the surface to be cleaned is a wall, "raise," "lift," and "retract" are all directions of movement away from the wall, while "lower," "descend," and "put down" are all directions of movement closer to the wall.

[0060] It should be noted that "the transmission component 400 oscillates along the rotation plane of the actuating component 500" does not mean that the transmission component 400 oscillates only along the rotation plane of the actuating component 500. In actual products, considering factors such as the smoothness of movement, the difficulty of assembly, manufacturing errors of parts, and assembly errors, there may be gaps between parts. Therefore, when the transmission component 400 oscillates along the rotation plane of the actuating component 500, the transmission component 400 may move in a direction perpendicular to the aforementioned rotation plane. However, since this movement is relatively slight, it will not affect the normal operation of the side brush device 10.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the side brush device 10 has two limiting surfaces 600, which are spaced apart along the rotation center line of the actuating member 500. The second end of the transmission member 400 is located between the two limiting surfaces 600. The two limiting surfaces 600 are respectively used to abut against the second end of the transmission member 400, and the two limiting surfaces 600 together limit the second end of the transmission member 400 on the rotation plane of the actuating member 500. The actuating member 500 has two abutting surfaces 510 spaced apart along its circumference. The second end of the transmission member 400 is located between the two abutting surfaces 510, and each abutting surface 510 is used to abut against the second end of the transmission member 400. When the actuating member 500 rotates relative to the mounting housing 100, one of the abutting surfaces 510 pushes the second end of the transmission member, causing one of the abutting surfaces 510 to push the transmission member 400 to swing along the rotation plane of the actuating member 500 through the abutting force.

[0062] like Figure 5 and Figure 6As shown, in this embodiment, when the cleaning brush 300 is switched from the cleaning position to the retracted position, the actuating member 500 rotates relative to the mounting shell 100 in direction A, causing one of its contact surfaces 510 to push the second end of the transmission member 400, thereby causing the transmission member 400 to swing along the rotation plane of the actuating member 500 in direction B. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 not only rotates around the second axis 401 in direction C1, but also drives the rotating member 200 to rotate around the first axis 210 in direction D, so that the cleaning brush 300 is switched from the cleaning position to the retracted position.

[0063] Conversely, such as Figure 7 As shown, when the sweeping brush 300 is switched from the retracted position to the sweeping position, the actuating member 500 rotates relative to the mounting shell 100 in direction a, causing the other contact surface 510 to push the second end of the transmission member 400, thereby causing the transmission member 400 to swing along the rotation plane and direction b of the actuating member 500. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 not only rotates around the second axis 401 in direction C2, but also drives the rotating member 200 to rotate around the first axis 210 in direction D, so that the sweeping brush 300 is switched from the retracted position to the sweeping position.

[0064] like Figure 7 As shown, in some embodiments, each abutment surface 510 is an arc surface, and each abutment surface 510 protrudes towards another abutment surface 510, so that the contact stress between each abutment surface 510 and the transmission member 400 is small, which improves the smoothness of the operation of the side brush device 10 and extends the service life of the side brush device 10.

[0065] Of course, the contact surface 510 is not limited to a curved surface. For example, in other embodiments, each contact surface 510 may also be a plane, a protrusion, or an existing structure that can be used to drive the transmission member 400.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the two limiting surfaces 600 are a first limiting surface 610 and a second limiting surface 620, respectively. The first limiting surface 610 is disposed on the actuating member 500. The second limiting surface 620 is disposed on the mounting housing 100. The first limiting surface 610, the second limiting surface 620, and the two abutting surfaces 510 together form a receiving groove 601, and the second end of the transmission member 400 is located within the receiving groove 601.

[0067] It is understood that in other embodiments, the second limiting surface 620 may also be provided on the toggle member 500.

[0068] like Figure 1As shown, in some embodiments, the side brush device 10 further includes a mounting shaft 700, one end of which is connected to the mounting housing 100. The actuating member 500 is rotatably sleeved on the mounting shaft 700, so that the actuating member 500 and the mounting housing 100 are coaxially arranged.

[0069] like Figure 1 As shown, in some embodiments, the transmission member 400 includes a connecting portion 410, a transition portion 420, and a force-receiving portion 430 connected in sequence. The connecting portion 410 is rotatably connected to the rotating member 200, and the axis of rotation of the connecting portion 410 relative to the rotating member 200 is a second axis 401. The actuating member 500 is used to abut against the force-receiving portion 430. When the actuating member 500 rotates relative to the mounting housing 100, it pushes the force-receiving portion 430 to slide along the rotation plane of the actuating member 500, causing the transmission member 400 to oscillate along the rotation plane of the actuating member 500.

[0070] Furthermore, the force-bearing part 430 is a cylindrical structure, which reduces the contact stress between the force-bearing part 430 and the actuating member 500, which not only extends the service life of the side brush device 10, but also improves the smoothness of the operation of the side brush device 10.

[0071] Of course, the force-bearing part 430 is not limited to a cylindrical structure. For example, in other embodiments, the force-bearing part 430 can be a square structure, a flat structure, etc.

[0072] In some embodiments, the rotating member 200 is provided with a connecting hole 201, and the connecting part 410 is rotatably connected to the connecting hole 201, so that the connecting part 410 and the rotating member 200 are rotatably connected together.

[0073] It is understood that in other embodiments, the connecting portion 410 may be omitted from the transmission member 400. Specifically, the connecting hole 201 is provided in the transition portion 420, and the outer side of the rotating member 200 is provided with a connecting shaft. The connecting shaft is located in the connecting hole 201 and is rotatably connected to the transmission member 400, so as to realize the rotatable connection between the transmission member 400 and the rotating member 200.

[0074] like Figure 2 As shown, in some embodiments, the mounting housing 100 is provided with a rotation area 101, and the rotating member 200 is located within the rotation area 101 and rotatably connected to the mounting housing 100. In this embodiment, since the rotating member 200 is located within the rotation area 101, the inner wall of the rotation area 101 can restrict the position of the rotating member 200 to ensure that the rotating member 200 rotates at a predetermined position within the mounting housing 100.

[0075] In some embodiments, the mounting housing 100 has a clearance opening 102 on its periphery that communicates with the rotating area 101. The cleaning brush 300 passes through the clearance opening 102, so that the cleaning brush 300 can extend out of the outside of the mounting housing 100, thereby increasing the cleaning range of the cleaning brush 300.

[0076] like Figure 2 As shown, in some embodiments, the mounting shell 100 includes a first shell 110 and a second shell, the first shell 110 and the second shell are fixedly connected, the first shell 110 is provided with a first rotating groove 111, the second shell is provided with a second rotating groove, and the first rotating groove 111 and the second rotating groove together form a rotating area 101.

[0077] Example 2:

[0078] The difference between this embodiment and Embodiment 1 is that this embodiment further refines the cleaning brush 300 of this application.

[0079] like Figure 2 As shown, in this embodiment, the cleaning brush 300 is fixedly connected to the rotating member 200, and the extending direction of the cleaning brush 300 forms an angle with the first axis 210. When the rotating member 200 rotates around the first axis 210, the cleaning brush 300 rotates and rises and falls as a whole around the first axis 210.

[0080] like Figure 2 and Figure 3 As shown, in this embodiment, when the cleaning brush 300 is switched from the cleaning position to the retracted position, the rotating member 200 rotates around the first axis 210 and in the direction D, so that the entire cleaning brush 300 rotates around the first axis 210 and in the direction D, thereby raising the cleaning end of the cleaning brush 300 to the retracted position.

[0081] Conversely, such as Figure 4 As shown, when the sweeping brush 300 is switched from the retracted position to the sweeping position, the rotating component 200 rotates around the first axis 210 in the direction d, causing the sweeping brush 300 as a whole to rotate around the first axis 210 in the direction d, thereby causing the sweeping end of the sweeping brush 300 to descend to the sweeping position.

[0082] Example 3:

[0083] The difference between this embodiment and Embodiment 1 is that this embodiment further refines the cleaning brush 300 of this application. The difference between this embodiment and Embodiment 2 is that the cleaning brush 300 of this embodiment is different from the cleaning brush 300 of Embodiment 2.

[0084] like Figure 8As shown, the cleaning brush 300 in this embodiment includes a mounting arm 310 and a bristle arm 320. The mounting arm 310 is coaxially arranged and fixedly connected to the rotating member 200. The bristle arm 320 is connected to the mounting arm 310. There is an angle between the bristle arm 320 and the mounting arm 310, so that when the rotating member 200 rotates around the first axis 210, it drives the cleaning brush 300 to flip.

[0085] like Figure 9 As shown, in this embodiment, when the cleaning brush 300 is switched from the cleaning position to the retracted position, the rotating member 200 rotates around the first axis 210 and in the direction D, the mounting arm 310 of the cleaning brush 300 rotates around the first axis 210 and in the direction D, and the bristle arm 320 of the cleaning brush 300 flips away from the surface to be cleaned, so that the bristle arm 320 is switched to the retracted position.

[0086] Conversely, such as Figure 10 As shown, when the cleaning brush 300 is switched from the retracted position to the cleaning position, the rotating component 200 rotates around the first axis 210 in the direction d, the mounting arm 310 of the cleaning brush 300 rotates around the first axis 210 in the direction d, and the bristle arm 320 of the cleaning brush 300 flips towards the surface to be cleaned, thus switching the bristle arm 320 to the cleaning position. In this way, the rotation of the rotating component 200 can cause the cleaning brush 300 to flip, thereby allowing the cleaning brush 300 to switch between the cleaning position and the retracted position.

[0087] Example 4:

[0088] This application discloses an automatic cleaning device, including a driving device and a side brush device 10 of any of the above embodiments. The driving device is connected to one of the toggle member 500 and the mounting shell 100 in a transmission manner. The driving device is used to make the toggle member 500 rotate relative to the mounting shell 100.

[0089] In some embodiments, the drive device is connected to the toggle member 500, and the drive device drives the toggle member 500 to rotate, so that the toggle member 500 rotates relative to the mounting housing 100.

[0090] In another embodiment, the drive device is connected to the mounting housing 100 in a transmission manner, and the drive device drives the mounting housing 100 to rotate, causing the actuating member 500 to rotate relative to the mounting housing 100.

[0091] Compared with the prior art, this application has at least the following advantages:

[0092] 1. When the actuating member 500 rotates relative to the mounting housing 100, the actuating member 500 pushes the second end of the transmission member 400. After being pushed by the actuating member 500, the transmission member 400 swings along the rotation plane of the actuating member 500. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 will not only rotate around the second axis 401, but also drive the rotating member 200 to rotate around the first axis 210, so as to drive the sweeping brush 300 to switch between the sweeping position and the retracted position.

[0093] 2. By rotating the actuating component 500 relative to the mounting housing 100, the sweeping brush 300 can be switched between the sweeping position and the retracted position. Since the relative rotation between the actuating component 500 and the mounting housing 100 does not involve lifting or lowering, there is no need to reserve lifting or lowering space for the actuating component 500 and the mounting housing 100. That is, there is no need to reserve lifting or lowering space for the components that drive the sweeping brush 300 to lift or lower, which makes the automatic cleaning equipment more compact in the thickness direction, which is beneficial to improving the passability of the automatic cleaning equipment.

[0094] 3. The mounting housing 100 is rotatably connected to the actuating component 500, and the transmission component 400 is rotatably connected to the mounting housing 100. The actuating component 500 abuts against the transmission component 400, so that the side brush device 10 lifts the cleaning brush 300 through multiple low-pair transmissions. This simplifies the structure of the side brush device 10, reduces the design, manufacturing and assembly difficulty of the side brush device 10, and also reduces the wear caused by the transmission. This not only extends the service life of the side brush device 10, but also improves the working stability of the side brush device 10.

[0095] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
