[0031] The side brush assembly provided by this utility model includes a side brush shell, a bearing sleeve, a brush structure, a rotating component, a transmission component, and an elastic component. The bearing sleeve is fixedly connected to the top of the side brush shell. The brush structure is provided inside the side brush shell, and multiple brushes of the brush structure can extend from the side brush shell to clean the surface to be cleaned (such as the ground). Furthermore, a rotating component is also provided inside the side brush shell, connected to the bearing sleeve and the rotating component via the transmission component. When the transmission component is subjected to external force and rotates in a first direction, it can drive the entire side brush assembly to rotate together, and the brush structure is in a lowered position. At this time, the brushes are in contact with the ground, and the side brush assembly is in normal cleaning operation. When the transmission component rotates in the second direction under the action of an external force, it drives the rotating component to rotate relative to the side brush housing. With the cooperation of the first and second abutting parts, the rotating component moves upward along the side brush housing, causing the brush structure to move upward along the side brush housing to a raised position. At this time, the brush component is separated from the ground. Therefore, when cleaning special areas (such as water-stained areas or carpeted areas), the transmission component can be driven to rotate in the second direction to raise the brush structure upward, allowing the brush component to move away from the special area without causing secondary pollution, thus better ensuring the cleaning effect of the cleaning equipment. Furthermore, an elastic element is provided inside the side brush housing. When the brush structure moves from the raised position to the lower position, the elastic element can elastically support the bottom of the brush structure.

[0045] This utility model provides a side brush assembly 100, which is suitable for cleaning equipment, such as sweepers, floor scrubbers, or sweeper-mop combos. For ease of explanation, the following description mainly uses the side brush assembly 100 as an example of a sweeper; other equipment can be adapted accordingly.

[0046] Specifically, please refer to Figure 1 and Figure 2 In this embodiment, the side brush assembly 100 includes a side brush shell 1, a bearing sleeve 2, a brush structure 3, a rotating component 4, a transmission component, and an elastic component 5. The top of the side brush shell 1 has a first through hole 13, and the periphery of the side brush shell 1 has multiple second through holes 14. A first abutment portion 15 is provided inside the side brush shell 1. The bearing sleeve 2 is fixedly fitted inside the first through hole 13. The brush structure 3 includes a main body 31 and multiple brush members 32 disposed around the periphery of the main body 31. The multiple brush members 32 are correspondingly inserted into the multiple second through holes 14 and at least partially protrude from the multiple second through holes 14. The rotating component 4 connects to the main body 31 and is located between the main body 31 and the side brush shell 1. The rotating component 4 has a second abutment portion 421 that cooperates with the first abutment portion 15. The transmission component connects the rotating component 4 and the bearing sleeve 2. The elastic component 5 abuts between the brush structure 3 and the side brush shell 1. When the transmission component rotates in the first direction under the action of an external force, it drives the entire side brush assembly 100 to rotate as well, and the brush structure 3 is in a lowered position. When the transmission component rotates in the second direction under the action of an external force, it can drive the rotating component 4 to rotate relative to the side brush shell 1. With the cooperation of the first abutment part 15 and the second abutment part 421, the rotating component 4 can move upward along the side brush shell 1, driving the brush structure 3 to move upward along the side brush shell 1 to a raised position. The first and second directions are opposite, and when the brush structure 3 moves from the raised position to the lowered position, the elastic component 5 can provide a reverse elastic support force at the bottom of the brush structure 3.

[0047] In this embodiment, a bearing sleeve 2 is fixedly connected to the top of the side brush housing 1. A brush structure 3 is provided inside the side brush housing 1, with multiple brush members 32 extending from it. These brush members 32 clean the surface to be cleaned (e.g., the ground). A rotating member 4 is also provided inside the side brush housing 1, connected to the bearing sleeve 2 and the rotating member 4 via a transmission member. When the transmission member is subjected to external force and rotates in the first direction, it drives the entire side brush assembly 100 to rotate as well, and the brush structure 3 is in a lowered position. At this time, the brush members 32 are in contact with the ground, and the side brush assembly 100 is in a normal cleaning working state. When the transmission member is subjected to external force and rotates in the second direction, it drives the rotating member 4 to rotate relative to the side brush housing 1. With the cooperation of the first abutment part 15 and the second abutment part 421, the rotating member 4 can move upward along the side brush housing 1, driving the brush structure 3 to move upward along the side brush housing 1 to a raised position. At this time, the brush members 32 are separated from the ground.

[0048] Therefore, when cleaning special areas (such as water-stained areas or carpeted areas) with the cleaning equipment, the transmission component can be driven to rotate in the second direction to lift the brush structure 3 upwards, allowing the brush component 32 to move away from the special area without causing secondary pollution and better ensuring the cleaning effect of the cleaning equipment. Furthermore, an elastic element 5 is provided inside the side brush housing 1, which elastically supports the bottom of the brush structure 3 when it moves from the lifted position to the lowered position. When the brush structure 3 moves downwards, the elastic element 5 provides better support, preventing wear and damage to the brush structure 3 and better protecting it, thus extending the service life of the side brush assembly 100.

[0049] The side brush assembly 100 is generally located at the bottom of the main body of the cleaning equipment. The brushes 32 of the side brush assembly 100 rub against the ground to clean it. The side brush assembly 100 is driven to rotate by a drive mechanism within the main body of the equipment, allowing multiple brushes 32 to rotate and increasing the friction efficiency between the brushes 32 and the ground, thereby improving cleaning efficiency. The output shaft of the drive mechanism can be integrally formed with the transmission component, or the output shaft of the drive mechanism can be connected to the transmission component. The drive mechanism controls the rotation of the transmission component, thereby driving the brush structure 3 to rotate for cleaning or to move up and down.

[0050] Understandably, for the brush structure 3 to rotate along with the transmission component when it rotates in the first direction, the bearing sleeve 2 needs to rotate along with the transmission component, causing the entire side brush housing 1 to rotate together, thus allowing the entire side brush assembly 100 to rotate and enter the cleaning state. However, when the transmission component rotates in the second direction, the brush structure 3 does not need to rotate. In this case, the bearing sleeve 2 needs to remain stationary, while the transmission component can rotate relative to the bearing sleeve 2.

[0051] Among them, a limiting component can be provided on the outer periphery of the bearing sleeve 2 to restrict the bearing sleeve 2 from rotating in the second direction, so that when the transmission component rotates in the second direction, the bearing sleeve 2 and the side brush shell 1 are in a stationary state.

[0052] Preferably, combined with Figures 2 to 4 As shown, the rotating component 4 is arranged in a ring shape and coaxially with the bearing sleeve 2. The two ends of the transmission component are respectively fitted inside the bearing sleeve 2 and the rotating component 4. The side brush assembly 100 also includes a one-way bearing, which is mounted on an external component to be installed, such as the drive housing of the drive mechanism. The one-way bearing sleeve 2 is located on the outer periphery of the bearing sleeve 2 to form the aforementioned limiting component. When the transmission component rotates along the first direction, the bearing sleeve 2 rotates along with the transmission component, keeping the side brush assembly 100 in a clean state. When the transmission component rotates along the second direction, the bearing sleeve 2 is stationary, and the transmission component can rotate relative to the bearing sleeve 2, preventing the brush structure 3 from rotating. The rotating component 4 rotates along with the transmission component, thereby lifting the brush structure 3.

[0053] There are many ways to achieve the lifting and lowering movement of the brush structure 3 by rotating a transmission component. In one embodiment, the transmission component can be a screw, and a nut screwed to the screw is provided on the brush structure 3. By rotating the transmission component in a second direction, the nut can move along the transmission component, thereby driving the entire brush structure 3 to move and achieve lifting and lowering.

[0054] In another embodiment, combined Figure 3 and Figure 4 As shown, the first abutment portion 15 includes a first wedge-shaped protrusion 151 located inside the side brush housing 1, and the second abutment portion 421 includes a second wedge-shaped protrusion 4211 located on the rotating member 4. The first wedge-shaped protrusion 151 and the second wedge-shaped protrusion 4211 form a wedge-shaped fit, so that when the rotating member 4 rotates in the second direction, the rotating member 4 can move upward relative to the side brush housing 1, driving the brush structure 3 to move upward together. Driven by the drive mechanism, the transmission member is driven to rotate in the second direction. The bearing sleeve 2 is restricted by the action of the one-way bearing, and the bearing sleeve 2 cannot rotate, nor can the side brush housing 1 rotate. The rotating member 4 rotates together under the action of the transmission member, so that the rotating member 4 can rotate relative to the side brush housing 1, and the second wedge-shaped protrusion 4211 rotates relative to the first wedge-shaped protrusion 151, thereby causing the rotating member 4 to move upward, driving the brush structure 3 to move upward together, so that the brush member is lifted to detach from the ground.

[0055] To better control the upward movement distance of the brush structure 3, preferably, a first limiting part 111 is provided on the side brush shell 1, and a first engaging part is provided on the rotating member 4. When in the raised position, the first limiting part 111 abuts against the first engaging part to limit the rotating member 4 from continuously rotating in the second direction, thus preventing the brush structure 3 from moving upward too much and causing interference.

[0056] Specifically, in combination Figure 4 and Figure 6 As shown, the first limiting part 111 includes a first limiting rib 1111 protruding from the top wall of the side brush housing 1, and the first mating part includes a first limiting boss on the rotating member 4. When the brush structure 3 is in the raised position, the first limiting boss and the first limiting rib 1111 form a stop-fit ​​in the second direction to restrict the rotating member 4 from continuously rotating in the second direction and keep the brush structure 3 in the raised position. When the brush structure 3 is in the lowered position, the first limiting boss and the first limiting rib 1111 move away from each other, so that the rotating member 4 has enough rotation space to rotate in the first direction and adjust the brush structure 3 to the lowered position.

[0057] Multiple first limiting ribs 1111 are provided, which surround the outer periphery of the first through hole 13 and extend radially from the first through hole 13 toward the edge of the side brush shell 1. Multiple first limiting bosses are also provided, which are arranged in a one-to-one correspondence with the multiple first limiting ribs 1111, so that the limiting of the rotating part 4 is more balanced and the rotating part 4 is prevented from tilting.

[0058] Of course, a corresponding limiting structure is also provided at the downward position of the brush structure 3, so that the brush structure 3 can be better maintained in the downward position. Specifically, a second limiting part 121 is provided on the side brush shell 1, and a second mating part 422 is provided on the rotating member 4. When in the downward position, the second limiting part 121 and the second mating part 422 abut against each other to limit the rotating member 4 from continuously rotating in the first direction, so as to avoid the brush structure 3 moving downward too much and causing interference.

[0059] Preferably, combined with Figure 4 and Figure 5 As shown, the second limiting part 121 includes a second limiting rib 1211 protruding from the bottom wall of the side brush housing 1, and the second mating part 422 includes a second limiting boss 4221 located on the outer periphery of the rotating member 4. When the brush structure 3 is in the lowered position, the second limiting boss 4221 and the second limiting rib 1211 form a stop-fitting engagement along the first direction to restrict the rotating member 4 from continuously rotating along the first direction, so that the brush structure 3 can be held in the lowered position for better cleaning. When the brush structure 3 is in the raised position, the second limiting boss 4221 and the second limiting rib 1211 move away from each other, so that the rotating member 4 can rotate along the second direction to move toward the raised position.

[0060] The side brush housing 1 is roughly cylindrical and hollow inside. Preferably, it is combined with... Figure 3 and Figure 4As shown, the side brush housing 1 includes an upper housing 11 and a lower housing 12 connected to each other, and the upper housing 11 and the lower housing 12 are detachably connected in the vertical direction. Both the upper housing 11 and the lower housing 12 are groove-shaped, so as to form an accommodating space between them for the installation of the rotating component 4, the brush structure 3 and the conductive component.

[0061] The first limiting part 111 is provided on the upper housing 11, and the second limiting part 121 is provided on the lower housing 12. The side brush assembly 100 also includes a connector and a sleeve screwed to the connector. The connector passes through the lower housing 12 from the outside and is inserted into the lower housing 12. The sleeve is located inside the lower housing 12 and is movably sleeved on the inner side of the transmission component. The connector can be a screw or bolt, and the transmission component can be a gear shaft of the output gear of the drive mechanism. The gear shaft is connected to the lower housing 12 through the sleeve and the connector to form a support, ensuring greater stability of the transmission component during rotation.

[0062] Moreover, combined Figure 2 and Figure 3 As shown, the brush structure 3 also includes a rubber ring 6, which is fitted onto the inner ring side of the main body 31. The rubber ring 6 is an elastic plastic part, which makes the connection between the brush structure 3 and the rotating component 4 more stable and prevents wear between the rotating component 4 and the main body 31. The main body 31 is annular in shape, with an annular groove on its inner ring side. Multiple reinforcing posts are provided within the annular groove, spaced apart along the circumference of the main body 31. The rubber ring 6 can be integrally formed with the main body 31, so that at least a portion of the rubber ring 6 is nested within the annular groove, and the multiple reinforcing posts limit the rubber ring 6, preventing it from detaching from the main body 31.

[0063] The rotating component 4 includes a rotating inner ring portion 41 and an extension portion 42 extending outward from one end of the rotating inner ring portion 41. The inner ring portion is fitted inside the rubber ring 6, and the extension portion 42 overlaps the upper end of the main body portion 31. The inner side of the inner ring portion forms an anti-rotation fit with the transmission component, so that the rotating component 4 can be better driven to rotate when the transmission component rotates. The inner ring hole of the rotating component 4 is square to better form an anti-rotation fit with the transmission component. A second wedge-shaped protrusion 4211 is provided on the upper end face of the rotating inner ring portion 41, and the height of the second wedge-shaped protrusion 4211 protruding from the upper end face of the rotating inner ring portion 41 gradually decreases along the second direction. The second wedge-shaped protrusion 4211 also forms the aforementioned first mating portion. The side end face of the highest end of the second wedge-shaped protrusion 4211 abuts against the first limiting rib 1111 on the upper housing 11 to restrict the rotating component 4 from continuing to rotate along the second direction. The second mating part 422 is formed on the extension part 42, and the second limiting boss 4221 extends outward in the radial direction.

[0064] Preferably, multiple second wedge-shaped protrusions 4211 are provided, and the multiple second wedge-shaped protrusions 4211 are arranged in a ring to surround the outer periphery of the inner ring hole of the rotating member 4. Multiple second limiting protrusions 4221 are also provided, and the multiple second limiting protrusions 4221 are evenly spaced along the circumferential direction on the outer periphery of the extension portion 42.

[0065] Furthermore, a first groove 122 is provided on the bottom wall of the side brush housing 1, and a second groove 61 opposite to the first groove 122 is provided on the rubber ring 6. The elastic element 5 includes a telescopic spring 51, with both ends of the telescopic spring 51 respectively housed in the first groove 122 and the second groove 61, making the fixation of the telescopic spring 51 more reliable. Moreover, when the brush structure 3 is in the raised position and the lowered position, the telescopic spring 51 is in a compressed state to better support the brush structure 3 and avoid wear on the brush structure 3 during the lifting and lowering process, thus affecting its service life.

[0066] This utility model also provides a cleaning device, which includes the aforementioned side brush assembly 100. This allows the cleaning device to perform normal cleaning work more effectively, and when traveling through special areas (such as water-stained areas, carpet areas, or areas with sticky, heavily soiled areas), the brush structure 3 of the side brush assembly 100 can be raised to move away from these areas, preventing secondary pollution, improving the cleaning function of the cleaning device, and extending its service life. The cleaning device can be configured as a sweeper, floor scrubber, or a combined sweeper and mop, etc.
