Figure 9 An exploded view of the side brush structure of the sweeper described in an embodiment of this application is shown; refer to Figure 10 This diagram illustrates the structural schematic of the side brush body of the sweeper according to an embodiment of this application. The sweeper may specifically include: a housing 10, a side brush structure 30, a cleaning unit 20, and a locking structure.

[0054] The side brush structure 30 is rotatably connected to the bottom of the housing 10, and the cleaning part 20 is spaced apart from the side brush structure 30;

[0055] The locking structure is disposed within the housing 10 and is connected to the side brush structure 30;

[0056] The side brush structure 30 has a plurality of extended brush strips 31, and the locking structure can lock the side brush structure 30 so that at least one brush strip 31 is located in the cleaning section 20 for cleaning the brush strip 31.

[0057] In this embodiment, the locking structure positions the side brush structure 30 so that the brush strip 31 used for cleaning is located in the cleaning section 20. The cleaning section 20 cleans easily generated debris such as hair, pet fur, or rope from the brush strip 31, giving the side brush structure 30 better cleaning performance and reducing the risk of motor stalling or even component damage. When cleaning is not required, the locking structure can be released, allowing the side brush structure 30 to operate normally and clean the floor.

[0058] In the embodiments of this application, such as Figure 2 The diagram shows the brush strip 31 located in the cleaning section 20, where the cleaning section 20 performs self-cleaning on the brush strip 31. Figure 3 The diagram shows the brush strip 31 not located in the cleaning section 20. In this case, the cleaning section 20 does not perform self-cleaning on the brush strip 31. Figure 4 As shown, the side brush structure 30 is prone to entanglement of hair, ropes, and other debris. For example... Figure 5 As shown, the arrows indicate the cleaning direction of the cleaning unit 20 for cleaning hair, ropes, and other debris. The cleaning unit 20 can clean hair, ropes, and other debris from the brush strip 31 in the direction of the arrows. Figure 6 As shown, the arrows also indicate the cleaning direction of the cleaning unit 20 for cleaning hair, ropes, and other debris. At this time, the cleaning unit 20 cleans the hair, ropes, and other debris off the brush strip 31 in the direction of the arrows, thus achieving a better self-cleaning function for the brush strip 31.

[0059] For example, in this embodiment, the cleaning unit 20 may be equipped with a roller brush to clean easily tangled debris such as hair, pet fur, or rope from the brush strip 31. Alternatively, the cleaning unit 20 may be equipped with a suction structure to absorb and clean debris such as hair, pet fur, or rope from the brush strip 31. The specific type of the cleaning unit 20 is not limited in this embodiment.

[0060] In this embodiment, the side brush structure 30 is rotatably connected to the housing 10, and the brush strip 31 contacts the ground. The rotation of the side brush structure 30 causes the brush strip 31 to clean the ground. For example, the side brush structure 30 can be located at the edge of the bottom of the housing 10; alternatively, it can be located in the middle of the bottom of the housing 10. Similarly, the cleaning part 20 can be located in the middle of the bottom of the housing 10; alternatively, the side brush structure 30 can be located at the edge of the bottom of the housing 10, etc. The specific locations of the side brush structure 30 and the cleaning part 20 are not limited in this embodiment.

[0061] For example, in this embodiment, the side brush structure 30 has multiple brush strips 31, such as two, three, five, or ten, etc., which can be set according to actual needs. This embodiment does not limit the specific number and setting method of the brush strips 31. The locking structure locks the side brush structure 30, which can place one of the brush strips 31 in the cleaning section 20, two of the brush strips 31 in the cleaning section 20, three of the brush strips 31 in the cleaning section 20, etc., which can be set according to the setting range of the cleaning section 20 and cleaning needs, etc., and this embodiment does not limit this as well.

[0062] In this embodiment, for example, the number of side brush structures 30 can be one, two, or three, etc., and the number of cleaning parts 20 can be set to one. Multiple side brush structures 30 can be distributed at intervals around the cleaning parts 20 on the edge of the housing 10, so that one cleaning part 20 can simultaneously clean the brush strips 31 of multiple side brush structures 30. Furthermore, the number of cleaning parts 20 can also be two or three, etc., with one side brush structure 30 corresponding to one cleaning part 20, or two side brush structures 30 sharing one cleaning part 20. This embodiment does not limit the specific number and arrangement of the cleaning parts 20 and the side brush structures 30.

[0063] Specifically, in this embodiment, the housing 10 provides space for the locking structure and connects the side brush structure 30 to the cleaning part 20. For example, the housing 10 can be made of plastic, metal, etc., and this embodiment does not limit the specific material and shape of the housing 10.

[0064] Optionally, in this embodiment, the locking structure includes a first transmission component and a locking member 43. The first transmission component is connected to the side brush structure 30, and the locking member 43 is connected to the first transmission component. The locking member 43 locks the movement of the first transmission component, thereby locking the side brush structure 30. In this way, the first transmission component enables the connection and transmission between the side brush structure 30 and the locking structure. The locking member 43 locks the first transmission component, thus stopping the rotation of the side brush structure 30 and allowing the brush strip 31 to be positioned in the cleaning section 20 for cleaning, achieving the self-cleaning function of the sweeper on the side brush structure 30.

[0065] Optionally, in this embodiment, the first transmission assembly includes a first transmission member 41 and a second transmission member 42. The first transmission member 41 is connected to the side brush structure 30, the second transmission member 42 is connected to the first transmission member 41, and the locking member 43 is connected to the second transmission member 42. Thus, the first transmission assembly is connected to the side brush structure 30 via the first transmission member 41, and the first transmission assembly is connected to the locking member 43 via the second transmission member 42. This provides a better transmission effect and facilitates configuration according to the spatial layout within the housing 10.

[0066] For example, the number of first transmission components 41 can be one, two, or three, etc., and can be set according to the actual needs based on the spatial volume of the housing 10 and the transmission and layout requirements. In this embodiment, the specific number of first transmission components 41 is not limited. Similarly, the number of second transmission components 42 can be two, two, or three, etc., and can be set according to the actual needs based on the spatial volume of the housing 10 and the transmission and layout requirements. In this embodiment, the specific number of second transmission components 42 is not limited.

[0067] Optionally, in this embodiment, the first transmission member 41 is an incomplete gear, the second transmission member 42 is a transmission gear, and the locking member 43 is a one-way bearing; the incomplete gear is connected to the side brush structure 30, the transmission gear meshes with the incomplete gear, and the one-way bearing is connected to the transmission gear; the side brush structure 30 rotates in a first direction, driving the incomplete gear to rotate, the incomplete gear driving the transmission gear to rotate, and the transmission gear driving the one-way bearing to rotate in the first direction; the side brush structure 30 rotates in a second direction, driving the incomplete gear to rotate, the incomplete gear driving the transmission gear to rotate in the second direction, and the one-way bearing locks the transmission gear, wherein the second direction is opposite to the first direction. Thus, the locking position of the side brush structure 30 is defined by the meshing position of the incomplete gear and the transmission gear, so that the brush strip 31 is located at the cleaning section 20 position, and the locking member 43 locks the rotation of the transmission gear, thereby locking the brush strip 31 of the side brush structure 30.

[0068] Specifically, in this embodiment, the incomplete gear can also be called a sector gear, which is a gear with only a portion of its teeth, meaning its number of teeth is incomplete. When the teeth of the incomplete gear mesh with the transmission gear, the incomplete gear drives the transmission gear to rotate. The incomplete gear and the transmission gear combine to form an incomplete gear mechanism, and the incomplete gear drives the transmission gear to rotate intermittently. Figure 7 As shown, the incomplete gear has two teeth. In addition, the incomplete gear can also have three or four teeth, etc., which can be set according to actual needs. In this embodiment, the specific number of teeth of the incomplete gear is not limited.

[0069] For example, in this embodiment of the application, when the side brush structure 30 is working normally and does not require self-cleaning, the side brush structure 30 rotates clockwise, driving the incomplete gear to rotate clockwise. The incomplete gear drives the transmission gear to rotate intermittently clockwise, and the transmission gear drives the one-way bearing to rotate clockwise. When the side brush structure 30 needs the brush strip 31 to be located in the cleaning section 20 for self-cleaning, the side brush structure 30 rotates counterclockwise, driving the incomplete gear to rotate counterclockwise. The incomplete gear drives the transmission gear to rotate counterclockwise, and the transmission gear drives the one-way bearing to have a tendency to rotate counterclockwise. However, the one-way bearing can only rotate clockwise and cannot rotate counterclockwise, thereby locking the counterclockwise rotation of the transmission gear and the incomplete gear, so that the brush strip 31 of the side brush structure 30 stops rotating in the cleaning section 20, realizing the self-cleaning function of the cleaning section 20 for the brush strip 31.

[0070] In this embodiment, the position of the teeth of the incomplete gear can be designed according to the setting position of the brush strip 31. When the incomplete gear rotates counterclockwise, the locking action of the one-way bearing ensures that when the incomplete gear is in a stopped position, the brush strip 31 is located within the area of ​​the cleaning section 20. The specific structural type, such as the position and number of teeth of the incomplete gear, can be set according to actual needs, and this embodiment does not limit this aspect.

[0071] In this embodiment, for example, the one-way bearing can rotate in a first direction, such as clockwise, but cannot rotate in the opposite direction, such as counterclockwise, thus achieving locking. Alternatively, the one-way bearing can also rotate counterclockwise, but cannot rotate clockwise, thus achieving locking. This embodiment does not limit the rotatable direction of the one-way bearing.

[0072] Optionally, in this embodiment, the sweeper further includes a driver 50 and a second transmission assembly connected to the driver 50. The second transmission assembly is disposed within the housing 10 and connected to the side brush structure 30. The driver 50 drives the second transmission assembly to rotate in a first direction or a second direction, the second direction being opposite to the first direction. The side brush structure 30 is also connected to the locking structure. Thus, the driver 50 provides a relatively stable and reliable driving force, and when the side brush structure 30 is cleaning the floor, the driver 50 outputs a driving force rotating in the first direction, driving the second transmission assembly to move and causing the side brush structure 30 to rotate and clean the floor in the first direction. At this time, the one-way bearing of the locking structure can rotate in the first direction without locking the side brush structure 30, avoiding any impact on the side brush structure 30 during floor cleaning. When the side brush structure 30 is self-cleaning its brush strips 31, the driver 50 outputs a driving force rotating in the second direction, driving the second transmission assembly to move, and the second transmission assembly causes the side brush structure 30 to rotate in the second direction. At this time, the locking structure locks the rotation of the side brush structure 30 through the one-way bearing and the first transmission assembly. Specifically, the side brush body 33 of the side brush structure 30 stops rotating, and the position of its brush strip 31 is locked.

[0073] For example, in the embodiments of this application, the driver 50 can be a motor or a motor, etc. The output end of the driver 50 is connected to the second transmission component to drive the second transmission component to rotate. The specific type of the driver 50 is not limited in the embodiments of this application.

[0074] Optionally, in this embodiment, the side brush structure 30 includes a side brush shell 32 and a side brush body 33. The side brush body 33 is provided with a plurality of brush strips 31, which extend out of the side brush shell 32. The side brush body 33 is rotatably connected to the side brush shell 32. The second transmission assembly is connected to the side brush shell 32, and the first transmission member 41 is connected to the side brush body 33. Thus, the second transmission assembly can drive the side brush shell 32 to rotate. When the side brush structure 30 reverses direction, the first transmission assembly can lock the rotation of the side brush body 33, preventing damage to the side brush structure 30 when it is locked by the locking structure.

[0075] For example, in this embodiment of the application, when the driver 50 drives the second transmission assembly to rotate in the first direction, the second transmission assembly drives the side brush housing 32 to rotate in the first direction, and the side brush housing 32 can drive the side brush body 33 to rotate in the first direction, so that the brush strips 31 on the side brush body 33 rotate to perform cleaning work on the ground. When the driver 50 drives the second transmission assembly to rotate in the opposite direction to the first direction, the second transmission assembly drives the side brush housing 32 to rotate in the second direction, the side brush housing 32 drives the side brush body 33 to rotate in the second direction, and the side brush body 33 drives the first transmission assembly to rotate in the second direction. The locking member 43 uses a reverse bearing to lock the rotation of the first transmission assembly in the second direction, so that at least one brush strip 31 is located in the cleaning part 20, and at the same time, the side brush housing 32 rotates relative to the side brush body 33 under the action of the second transmission assembly.

[0076] In this embodiment, for example, the side brush housing 32 has an opening on its side, and the side brush arm 35 of the side brush body 33 extends out of the side brush housing 32 from the opening. For example, the side brush housing 32 may include an upper shell and a lower shell, which together form a receiving cavity. The central portion of the side brush body 33 is located within the receiving cavity, facilitating assembly and improving assembly efficiency. Furthermore, the side brush housing 32 may be a one-piece structure or multiple separate structures; the specific type of the side brush housing 32 is not limited in this embodiment.

[0077] Optionally, in this embodiment, the second transmission component includes a first gear 61, a second gear 62, and a third gear 63; the first gear 61 is connected to the driver 50, the second gear 62 meshes with the first gear 61, the third gear 63 meshes with the second gear 62, and the side brush structure 30 is connected to the third gear 63. Specifically, the side brush shell 32 of the side brush structure 30 is connected to the third gear 63. Thus, the second transmission component is connected to the driver 50 via the first gear 61, the second transmission component is connected to the side brush structure 30 via the third gear 63, and the transmission between the first gear 61 and the third gear 63 is achieved via the second gear 62. This provides good transmission efficiency and reliability, and facilitates the design of the force transmission path based on the spatial layout within the housing 10.

[0078] For example, in this embodiment, the second gear 62 includes a first gear ring and a second gear ring spaced apart. The first gear ring meshes with the first gear 61, and the second gear ring meshes with the third gear 63, thereby achieving separate meshing of the second gear 62 with the first gear 61 and the third gear 63. Furthermore, the same gear ring of the second gear 62 can also mesh with both the first gear 61 and the third gear 63. This embodiment does not limit the specific type of the second gear 62.

[0079] In this embodiment, for example, the number of first gears 61 can be one, two, or three, etc., depending on the spatial volume of the housing 10 and the requirements for transmission and layout, and is set according to actual needs. This embodiment does not limit the specific number of first gears 61. Similarly, the number of second gears 62 can be two, two, or three, etc., depending on the spatial volume of the housing 10 and the requirements for transmission and layout, and is not limited in this embodiment. Furthermore, the number of third gears 63 can be three, two, or three, etc., depending on the spatial volume of the housing 10 and the requirements for transmission and layout, and is not limited in this embodiment.

[0080] Optionally, in this embodiment, the locking structure and the second transmission component are at least partially coaxial. This allows the locking structure and the second transmission component to be positioned on the same axis, saving the additional space required for separate arrangements, improving the space utilization of the housing 10, and facilitating product miniaturization.

[0081] Optionally, in this embodiment, the sweeper further includes a locking shaft 44, with the locking member 43 and the second gear 62 spaced apart and connected to the locking shaft 44. The second transmission member 42 is sleeved on the locking member 43, and the locking member 43, the second transmission member 42, and the second gear 62 are coaxially arranged. Figure 1 As shown, the locking shaft 44 can extend vertically, allowing the locking member 43 and the second gear 62 to be stacked vertically, reducing the horizontal dimension of the housing 10. Furthermore, the second transmission member 42 is fitted onto the locking member 43, further improving space utilization. Additionally, the locking shaft 44 passes through both the locking member 43 and the second gear 62, providing good structural stability.

[0082] Optionally, in this embodiment, the side brush structure 30 further includes a side brush shaft 34, one end of which is located inside the side brush housing 32, and the other end of which extends upward beyond the side brush housing 32. The side brush body 33 is connected to one end of the side brush shaft 34, and the first transmission member 41 is connected to the other end of the side brush shaft 34. In this way, the side brush body 33 of the side brush structure 30 is connected to the first transmission member 41 via the side brush shaft 34, and the other end of the side brush shaft 34 extends upward beyond the side brush housing 32, preventing the first transmission member 41 from affecting the movement of the housing 10. Furthermore, the first transmission member 41 can be fixedly connected to the outer periphery of the side brush shaft 34, providing good force transmission stability.

[0083] Optionally, in this embodiment, the side brush shaft 34 is disposed on the central axis of the side brush housing 32, and the third gear 63 of the second transmission assembly is coaxially disposed with the first transmission member 41. Figure 1 As shown, the side brush shaft 34 can extend vertically, so that the third gear 63 can be stacked with the first transmission member 41 in the vertical direction, reducing the horizontal dimension of the housing 10 and improving space utilization.

[0084] Optionally, in this embodiment, the side brush structure 30 is vertically connected to the housing 10. When the side brush structure 30 is raised close to the housing 10, the locking structure locks the side brush structure 30, ensuring that at least one brush strip 31 is located in the cleaning section 20. This allows the sweeper to return to the base station for self-cleaning. With the side brush structure 30 in a raised state, its distance from the ground prevents secondary contamination from contact with dirt, ensuring effective cleaning of the brush strips 31 by the cleaning section 20. Furthermore, when the sweeper is cleaning liquid dirt or in single-mopping mode, even when the side brush structure 30 is not in use, it can be raised to clean its brush strips 31, improving cleaning efficiency.

[0085] Optionally, in this embodiment, the side brush body 33 of the side brush structure 30 includes a side brush curved arm 35, and the brush strip 31 is connected to the side brush curved arm 35; the side brush structure 30 includes a side brush shell 32, and the side brush is bent and abuts against the upper surface inside the side brush shell 32, so that the side brush structure 30 is raised close to the shell 10. Thus, by bending the side brush curved arm 35 to fold it, it abuts against the upper surface inside the side brush shell 32, allowing the side brush structure 30 to achieve a raised state.

[0086] For example, in the embodiments of this application, when the side brush structure 30 is performing a floor cleaning operation, the side brush arm 35 can extend downward toward the ground. When the side brush structure 30 is switched to the raised state, the side brush arm 35 is bent and folded to extend toward an approximately horizontal direction and abuts against the upper surface inside the side brush housing 32 to maintain the raised state.

[0087] Optionally, in this embodiment, the side brush body 33 further includes a sleeve 36, which is sleeved on the side brush shaft 34 of the side brush structure 30. The side brush curved arm 35 is connected to the outer periphery of the sleeve 36, and a bending portion 37 is provided at one end of the side brush curved arm 35 near the sleeve 36. When the side brush shell 32 rotates in the second direction, the bending portion 37 bends so that the side brush curved arm 35 abuts against the upper surface inside the side brush shell 32. By providing the bending portion 37 at one end of the side brush curved arm 35 near the sleeve 36, the side brush curved arm 35 can be bent and flipped at the end near the sleeve 36, giving the side brush curved arm 35 a higher lifting height.

[0088] For example, in the embodiments of this application, the bending portion 37 can be a hollow structure. The shape of the hollow structure can be semi-circular, elliptical, or rectangular, etc., and can be set according to the stress conditions. The specific shape of the bending portion 37 is not limited in the embodiments of this application.

[0089] Optionally, in this embodiment, the upper surface of the side brush housing 32 is provided with a protruding abutment portion 38, and the side brush curved arm 35 is bent and abuts against the abutment portion 38. In this way, the side brush curved arm 35 has a more stable and reliable abutment effect with the side brush housing 32 through the abutment portion 38, thereby improving the structural stability of the side brush structure 30 when it is in the raised state.

[0090] For example, in the sweeper of this embodiment, when the sweeper is performing normal floor cleaning, the incomplete gear of the first transmission member 41 and the transmission gear of the second transmission member 42 are normally engaged, and the side brush performs normal floor cleaning. When the sweeper returns to the base station for cleaning, the side brush structure 30 will lift itself to a raised state, the drive motor will reverse, and the first gear 61, the second gear 62, and the third gear 63 will sequentially engage to drive the side brush shell 32 to reverse, thereby driving the side brush body 33 to reverse. The side brush body 33 and the side brush shaft 34 can be connected by a snap-fit. The side brush shaft 34 rotates synchronously with the incomplete gear of the first transmission member 41. When the incomplete gear rotates to engage with the transmission gear of the second transmission member 42, since the transmission gear of the second transmission member 42 rotates synchronously with the outer side of the one-way bearing, the one-way bearing will lock during the reverse rotation, causing the transmission gear, the incomplete gear, the side brush shaft 34, and the side brush body 33 to stop rotating. At this time, the side brush housing 32 will still rotate in reverse under the drive of the third gear 63, and the side brush body 33 and the side brush housing 32 will rotate relative to each other. At the same time, the protruding abutment part 38 on the inner upper surface of the side brush housing 32 will abut against the upper surface of the side brush curved arm 35, causing the side brush curved arm 35 to fold downward along its foldable bending part 37. This action will change the end of the side brush curved arm 35 from bending towards the ground to bending towards an approximately horizontal direction, thereby lifting the side brush. Since the position of the teeth of the incomplete gear can be set according to the actual situation, when the incomplete gear meshes with the transmission gear, after the side brush structure 30 is lifted, its side brush curved arm 35 is within the cleaning range of the roller brush of the cleaning part 20.

[0091] In this embodiment, the side brush arm 35 is exemplarily described as having a certain bending angle. When the side brush structure 30 is in a lowered state, the side brush arm 35 is bent downwards. When the sleeve 36 and the side brush shell 32 move relative to each other, the abutting portion 38 on the side brush shell 32 presses down on the sleeve 36. For example, the abutting portion 38 on the side brush shell 32 abuts downwards on the side brush arm 35, thereby causing the side brush arm 35 to fold downwards, and the bending direction of the side brush arm 35 changes. For example, the bending direction of the side brush arm 35 changes from downward bending to horizontal bending, thereby raising the height of the side brush arm 35. When the side brush arm 35 is in the raised state, the side brush structure 30 can be away from the ground. Therefore, when the cleaning robot is cleaning liquid dirt or performing single mopping mode, the side brush structure 30 can be folded away from the ground to avoid contact with dirt, improve the cleanliness of the side brush structure 30 and avoid secondary pollution during the cleaning process.

[0092] Optionally, in this embodiment, the abutting portion 38 may include a first abutting inclined surface and a second abutting surface connected to the first abutting inclined surface. When the side brush housing 32 rotates, the first abutting inclined surface abuts against the bent portion 37 of the side brush arm 35, causing the side brush arm 35 to rotate, thereby enabling the side brush structure 30 to clean the floor. When the side brush housing 32 moves relative to the sleeve 36, the first abutting inclined surface forms an abutting guide against the bent portion 37 of the side brush arm 35, causing the bent portion 37 of the side brush arm 35 to fold downwards, raising the height of the side brush structure 30. When the side brush structure 30 is raised to its highest point, the second abutting surface abuts against the bent portion 37 of the side brush arm 35.

[0093] In this embodiment, the second abutting surface connects with the first abutting inclined surface, or the second abutting surface can smoothly transition with the first abutting inclined surface. For example, when the side brush shell 32 rotates, the first abutting inclined surface of the abutting part 38 abuts against the bent part 37 of the side brush curved arm 35. The abutting force applied by the abutting part 38 to the bent part 37 of the side brush curved arm 35 drives the side brush structure 30 and the sleeve 36 to rotate synchronously, so that the side brush structure 30 remains in contact with the ground and performs ground cleaning. During the cleaning process of the side brush structure 30, when encountering large particles or debris of a certain thickness, the aforementioned abutting force keeps the side brush structure 30 pressed down and prevents it from being lifted up with the debris, further improving the cleaning effect of the side brush structure 30.

[0094] For example, in this embodiment of the application, when the side brush housing 32 and the sleeve 36 move relative to each other, the first abutting slope on the abutting part 38 forms an abutting guide for the bent part 37 of the side brush arm 35. This abutting guide can be understood as the abutting part 38 and the bent part 37 of the side brush arm 35 maintaining contact while the bent part 37 of the side brush arm 35 moves along the first abutting slope under the action of the abutting force. Thus, during the relative movement, the abutting part 38 gradually increases the abutting force on the bent part 37 of the side brush arm 35, causing the bent part 37 of the side brush arm 35 to be pressed down and fold downwards, thereby changing the bending direction of the side brush arm 35. The bending direction of the side brush arm 35 changes from downward bending to horizontal bending, thereby raising the height of the side brush arm 35 off the ground. Furthermore, when the side brush structure 30 is raised to its highest position, the bent portion 37 of the side brush arm 35 abuts against the second abutting surface. The second abutting surface is further provided with a chamfer at a position away from the first abutting slope, and this chamfer is used to avoid the side brush structure 30.

[0095] In some alternative embodiments, the second abutting surface on the abutting portion 38 can be extended along the circumferential length of the sleeve 36, thereby further increasing the relative rotation range between the side brush shell 32 and the sleeve 36, which facilitates the lifting or lowering control of the side brush structure 30.

[0096] For example, in some embodiments, the thickness of the bent portion 37 of the side brush arm 35 in the radial direction of the sleeve 36, away from the center of the sleeve 36, is greater than the thickness near the center of the sleeve 36. In this embodiment, the thickness of the bent portion 37 of the side brush arm 35 refers to the thickness of the bent portion 37 of the side brush arm 35 along the axial direction of the sleeve 36. The center thickness of the bent portion 37 of the side brush arm 35 in the radial direction of the sleeve 36 is relatively thin. This facilitates the application of abutment force by the abutment portion 38 to the bent portion 37 of the side brush arm 35, allowing the thinner area of ​​the bent portion 37 of the side brush arm 35 to bend downwards, forming a foldable feature on the side brush arm 35. Furthermore, the bending direction of the side brush arm 35 can be changed by folding the bent portion 37 of the side brush arm 35, thereby achieving a height increase of the side brush arm 35.

[0097] In some embodiments, the thickness of the bent portion 37 of the side brush arm 35 near the center of the sleeve 36 is less than the thickness away from the center of the sleeve 36 along the radial direction. This allows the bent portion 37 of the side brush arm 35 to form an arc-shaped groove or a V-shaped groove, etc., along the radial direction of the sleeve 36. The bent portion 37 of the side brush arm 35 abuts against the abutting portion 38. This makes it easier for the bent portion 37 of the side brush arm 35 to be pressed down, and causes deformation at the thinner center of the bent portion 37, causing the bent portion 37 of the side brush arm 35 to fold downwards, thereby changing the bending direction of the side brush arm 35.

[0098] In one optional embodiment, the bending portion 37 of the side brush arm 35 can be made of rubber material. In this embodiment, the side brush arm 35 can be made of rubber material with good deformation properties, thereby enabling the bending portion 37 of the side brush arm 35 to have good deformation performance. This allows the bending portion 37 to maintain structural stability during repeated deformation, thus improving the service life of the bending portion 37 of the side brush arm 35.

[0099] The inner circumference of the side brush body 33 may be provided with a side brush limiting part, and the sleeve 36 is provided with a transmission limiting part. The side brush limiting part cooperates with the transmission limiting part to limit the side brush body 33 along the radial direction of the sleeve 36.

[0100] In this embodiment, a side brush limiting portion is provided on the inner circumference of the side brush body 33, and a corresponding transmission limiting portion is provided on the sleeve 36. In some embodiments, the side brush limiting portion can be a limiting groove, and the transmission limiting portion can be a limiting protrusion that matches the shape of the limiting groove. In other embodiments, the side brush limiting portion can be a limiting protrusion, and the transmission limiting portion can be a limiting groove that matches the shape of the limiting protrusion. Thus, when the side brush body 33 is sleeved on the sleeve 36, the side brush limiting portion and the transmission limiting portion cooperate to limit the side brush body 33 radially along the sleeve 36.

[0101] For example, in this embodiment of the application, the sleeve 36 can be a plastic part. After the side brush body 33 is sleeved on the sleeve 36, the sleeve 36 is then injection molded a second time, so that the side brush body 33 can be limited along the axial direction of the sleeve 36.

[0102] In some optional embodiments, the number of side brush arms 35 can be at least two, and the at least two side brush arms 35 are distributed at equal angles about the central axis of the side brush body 33 in the horizontal circumferential direction. Those skilled in the art can determine the number of side brush arms 35 according to actual design requirements, and no further limitations are made here. As a preferred embodiment, the number of side brush arms 35 can be three.

[0103] In some optional embodiments, the side brush structure 30 further includes an elastic element sleeved on the sleeve 36. A first end of the elastic element is fixed to the side brush shell 32, and a second end of the elastic element is fixed to the sleeve 36, so that the side brush arm 35 can be folded back to its original position through the deformation recovery of the elastic element. When the side brush shell 32 rotates the side brush structure 30, the elastic element provides a torsional force to keep the abutting portion 38 in contact with the side brush structure 30. When the side brush shell 32 and the side brush structure 30 move relative to each other, the torsional force of the elastic element increases, and the side brush structure 30 is folded back to its original position through the torsional recovery of the elastic element.

[0104] In this embodiment, the elastic element is sleeved on the sleeve 36, and its two ends are fixed to the sleeve 36 and the side brush shell 32, respectively. For example, the elastic element may include a torsion spring, with its first end fixed to the upper half of the side brush shell 32 and its second end fixed to the sleeve 36. Thus, an elastic connection is formed between the sleeve 36 and the side brush shell 32 along the circumference of the sleeve 36 through the elastic element.

[0105] In other embodiments, the first end of the elastic member can be fixed to the lower half of the side brush housing 32, and the second end of the elastic member can be fixed to the sleeve 36. This allows an elastic connection to be formed between the sleeve 36 and the lower half of the side brush housing 32 along the circumference of the side brush drive member. When the abutting part 38 abuts against the side brush arm 35, causing the side brush arm 35 to rotate synchronously, and the side brush structure 30 is in a lowered state, the deformation and torsional force of the elastic member maintains the contact between the abutting part 38 and the side brush arm 35. This allows the side brush structure 30 to remain in contact with the ground, and the rotation of the side brush structure 30 performs ground cleaning.

[0106] When the side brush shell 32 is subjected to an external force and rotates relative to the sleeve 36, the elastic potential energy (also known as the deformation torsional force) of the elastic element increases, thereby increasing the abutting force of the abutting part 38 on the side brush curved arm 35. The abutting part 38 presses down on the side brush curved arm 35, causing the side brush curved arm 35 to fold downward.

[0107] When the side brush housing 32 drives the sleeve 36 to rotate synchronously again, under the torsional recovery action of the elastic element, the bent portion 37 of the side brush arm 35 moves along the abutting portion 38, and the abutting force of the abutting portion 38 on the bent portion 37 of the side brush arm 35 gradually decreases, thereby restoring the deformation of the bent portion 37 of the side brush arm 35. The bending direction of the side brush arm 35 is restored to a horizontal downward state. And through the deformation torsional force of the elastic element, the abutting portion 38 and the side brush arm 35 are kept in contact, thereby allowing the side brush structure 30 to maintain contact with the ground, and the ground is cleaned by the rotation of the side brush structure 30.

[0108] In summary, the sweeping machine described in the embodiments of this application may include at least the following advantages:

[0109] In this embodiment, the sweeper includes: a housing, a side brush structure, a cleaning section, and a locking structure. The side brush structure is rotatably connected to the bottom of the housing, and the cleaning section is spaced apart from the side brush structure. The locking structure is disposed within the housing and connected to the side brush structure. The side brush structure has multiple extending brush strips, and the locking structure can lock the side brush structure, so that at least one brush strip is located in the cleaning section for cleaning. Thus, by positioning the side brush structure using the locking structure, the brush strips used for cleaning are positioned in the cleaning section. The cleaning section removes easily generated debris such as hair, pet fur, or rope from the brush strips, resulting in better cleaning performance and reducing the risk of motor stalling or even component damage. When cleaning the side brush structure is not required, the locking structure can release the lock, allowing the side brush structure to operate normally and clean the floor.
