Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more specifically to a cleaning device. Background Technology

[0002] A floor scrubber is a cleaning device suitable for home use, primarily used for cleaning and washing household floor surfaces. Floor scrubbers typically have water spraying and suction functions; they automatically spray water and scrub the floor, then suck the wastewater and residual dirt into the machine's wastewater tank. Floor scrubbers are easy to use and provide a thorough cleaning result.

[0003] However, currently, users typically turn the floor scrubber by rotating the machine body to make the floor brush turn. The excessively large turning radius of the floor brush results in a smaller coverage area when cleaning narrow areas such as under beds and table corners, easily creating cleaning blind spots. Furthermore, the user's ability to maneuver the brush to turn is not flexible enough. Utility Model Content

[0004] This application provides a cleaning device that can reduce the turning radius of the floor brush to improve the cleaning effect of the floor brush in narrow areas, and make the turning of the floor brush more flexible.

[0005] This application provides a cleaning device. The cleaning device includes a body and a floor brush, the body being rotatably connected to the floor brush. The body has a handle for gripping, and the floor brush is used to clean the surface to be cleaned. The floor brush includes a brush body connected to the body. The floor brush also includes a cleaning component disposed on the brush body, used for cleaning the surface to be cleaned. The cleaning device also includes an auxiliary wheel for assisting the movement of the floor brush. The cleaning device further includes a steering knuckle rotatably disposed on the brush body and connected to the auxiliary wheel. The axis of rotation of the steering knuckle relative to the brush body is denoted as a first axis of rotation, and the angle between the first axis of rotation and the surface to be cleaned is greater than or equal to 85°. The cleaning device also includes a drive assembly, which is drivenly connected to the steering knuckle. The drive assembly is configured to drive the steering knuckle to rotate about the first axis of rotation, thereby causing the auxiliary wheel to deflect on the surface to be cleaned.

[0006] In this application, the auxiliary wheel is deflected by a drive component. The deflected auxiliary wheel reduces the overall resistance of the floor brush during turning. The user only needs to gently push the handle in the desired turning direction, without needing to twist their wrist, to move in the direction of least resistance under the guidance of the deflected auxiliary wheel. This makes the overall turning radius of the floor brush approach the turning radius guided by the auxiliary wheel, significantly reducing the overall turning radius. This is particularly suitable for flexible steering in narrow spaces, and the thrust is effectively converted into turning force, making the entire turning process easy and effortless. If the auxiliary wheel cannot actively deflect and instead moves in tandem with the original direction of the floor brush... If the forward direction remains consistent, when the user needs to make a turn, they will find that the expected turning direction of the brush is at a large angle to its original forward direction. When the user pushes the brush, because the resistance is least in the original forward direction, the brush will involuntarily move to one side of its original forward direction, resulting in a very large turning radius. This is not conducive to use in narrow areas, and the user's pushing force is difficult to convert into turning force. The user needs to drag the brush by pulling the body to reduce the turning radius. However, the overall weight of the body and the brush is relatively heavy, which puts too much strain on the user's wrist and affects the user experience.

[0007] In one embodiment of this application, the floor brush has a first direction and a second direction, the first direction and the second direction are perpendicular to each other, and both the first direction and the second direction are parallel to the surface to be cleaned.

[0016] In one embodiment of this application, the drive assembly further includes a steering tie rod, one end of which is pivotally connected to a moving member and the other end of which is pivotally connected to a steering knuckle.

[0044] This application provides a cleaning device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0045] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the cleaning device of this application.

[0046] In one embodiment, the cleaning device 10 can be a floor scrubber or other cleaning equipment. The user holds the cleaning device 10 and pushes it across the floor, the surface of the item to be cleaned, or the cleaning surface 10a, allowing the cleaning device 10 to clean the area it passes over. Alternatively, the cleaning device 10 can be a cleaning robot or other cleaning equipment. The cleaning device 10 can move autonomously across the cleaning surface 10a and clean the area it passes over. This application uses a floor scrubber as an example for illustration, but this is not intended to limit the scope of the invention.

[0047] Specifically, the cleaning device 10 includes a body 20 and a floor brush 30. The body 20 is rotatably connected to the floor brush 30. The body 20 is provided with a handle for gripping. The floor brush 30, also called a cleaning head or suction head, is used to clean the surface 10a to be cleaned. The floor brush 30 includes a brush body 31 and a cleaning element 32. The brush body 31 is rotatably connected to the body 20. The cleaning element 32 is disposed on the brush body 31 and is used to clean the surface 10a to be cleaned. By gripping the handle on the body 20, the user moves the floor brush 30 across the surface 10a to be cleaned, and the cleaning element 32 on the brush 30 can clean the area it passes over. The cleaning element 32 can be a roller brush, a cleaning brush, a bristle brush, a brush disc, etc., and is not limited here. The cleaning device 10 also includes an auxiliary wheel 40, which is used to assist the movement of the floor brush 30. The auxiliary wheel 40 can specifically be disposed on the brush body 31.

[0048] Please refer to the following: Figure 2 and Figure 3 , Figure 2 yes Figure 1 A schematic diagram of the cleaning device from another perspective. Figure 3 yes Figure 1 A schematic diagram of the drive assembly of the cleaning device shown.

[0049] In one embodiment, the cleaning device 10 further includes a drive assembly 50, which is kinetically connected to the auxiliary wheel 40. The drive assembly 50 is configured to drive the auxiliary wheel 40 to rotate about a first rotation axis O1, thereby causing the auxiliary wheel 40 to deflect on the surface 10a to be cleaned. Thus, when the user pushes the cleaning device 10 forward, the deflected auxiliary wheel 40 can guide the floor brush 30 to turn in the corresponding direction.

[0050] In this embodiment, the auxiliary wheel 40 is configured to deflect relative to the brush body 31. The drive assembly 50 drives the auxiliary wheel 40 to rotate about the first rotation axis O1, so that when the user pushes the cleaning device 10 forward, the deflected auxiliary wheel 40 guides the brush 30 to turn on the surface 10a to be cleaned. The deflection of the auxiliary wheel 40 relative to the brush body 31 reduces the turning radius of the brush 30, increasing the area covered by the brush 30 when cleaning narrow areas, thereby improving the cleaning effect of the brush 30 on narrow areas, and making the turning of the brush 30 more flexible.

[0051] In one embodiment, the cleaning device 10 further includes a steering knuckle 60, which is rotatably disposed on the floor brush body 31. The drive assembly 50 is connected to the auxiliary wheel 40 via the steering knuckle 60. The axis of rotation of the steering knuckle 60 relative to the floor brush body 31 is denoted as the first axis of rotation O1.

[0052] In this embodiment, the auxiliary wheel 40 is configured to deflect relative to the brush body 31. The drive assembly 50 drives the steering knuckle 60 to rotate around the first rotation axis O1, causing the auxiliary wheel 40 to rotate synchronously around the first rotation axis O1. This allows the deflected auxiliary wheel 40 to guide the brush 30 to turn on the surface 10a to be cleaned when the user pushes the cleaning device 10 forward. The deflection of the auxiliary wheel 40 relative to the brush body 31 reduces the turning radius of the brush 30, increasing the area covered by the brush when cleaning narrow areas, thereby improving the cleaning effect of the brush on narrow areas and making the brush more flexible in turning.

[0053] The driving component 50 of the present application embodiment will be described below.

[0054] Please refer to the following: Figure 4 , Figure 4 yes Figure 3 The diagram shows the exploded structure of the driving component.

[0055] In one embodiment, the floor brush 30 has a first direction X and a second direction Y, the first direction X and the second direction Y are perpendicular to each other, and both the first direction X and the second direction Y are parallel to the surface 10a to be cleaned. The first direction X is the traveling direction of the floor brush 30, and the cleaning component 32 is disposed near the front end of the floor brush body 31 in the first direction X.

[0056] The drive assembly 50 includes a drive member 51 and a moving member 52. The drive member 51 is connected to the steering knuckle 60 via the moving member 52. The drive member 51 is configured to drive the moving member 52 to move in the second direction Y or the opposite direction of the second direction Y, so that the moving member 52 drives the steering knuckle 60 to rotate around the first rotation axis O1.

[0057] Specifically, the drive unit 51 includes a servo motor 511 and a steering arm 512. The steering arm 512 is rotatably mounted on the servo motor 511 and is drively connected to the moving member 52. The servo motor 511 is configured to drive the steering arm 512 to rotate, thereby causing the moving member 52 to move along the second direction Y or the opposite direction of the second direction Y. Further, the drive assembly 50 also includes a steering tie rod 53. One end of the steering tie rod 53 is pivotally connected to the moving member 52, and the other end is pivotally connected to the steering knuckle 60. When the moving member 52 moves along the second direction Y or the opposite direction of the second direction Y, the moving member 52 causes the steering knuckle 60 to rotate around the first rotation axis O1 via the steering tie rod 53. The two ends of the steering tie rod 53 are pivotally connected to the moving member 52 and the steering knuckle 60 respectively, enabling the steering tie rod 53 to support a drive method in which the moving member 52 moves along the second direction Y or the opposite direction of the second direction Y to rotate the steering knuckle 60.

[0058] For example, the floor brush 30 has auxiliary wheels 40 on both sides of the moving part. Each auxiliary wheel 40 is pivotally connected to the moving part 52 through a corresponding steering knuckle 60 and steering tie rod 53. The moving part can drive each auxiliary wheel to rotate in the same direction.

[0059] As the auxiliary wheel 40 guides the brush 30, it rolls around its own central axis. The steering knuckle 60 is located on the rotational central axis of the auxiliary wheel 40, i.e., in the second direction Y. The auxiliary wheel 40, steering knuckle 60, and brush body 31 move along... Figure 2 The distribution is shown in the left-right direction. The drive assembly 50 is connected to each steering knuckle 60. The drive assembly 50 is configured to synchronously drive each steering knuckle 60 to rotate around its respective first rotation axis O1, and the rotation direction of each steering knuckle 60 is the same, causing the auxiliary wheels 40 on both sides of the floor brush 30 to deflect in the same direction. The auxiliary wheels 40 on both sides of the floor brush 30 cooperate to guide the floor brush 30 to turn in the corresponding direction. The steering knuckles 60 connected to each auxiliary wheel 40 are located on the same side of the moving member 52 in the first direction X, and on both sides of the moving member 52 in the second direction Y, so that the moving member 52 can drive each steering knuckle 60 to rotate in the same direction. The moving member 52 is away from the cleaning member 32 relative to the steering knuckle 60 in the first direction X.

[0060] like Figure 5 As shown, when the user wants to control the brush 30 to turn left, the servo motor 511 drives the rudder arm 512 to... Figure 5 When the rudder arm 512 rotates to the right, it drives the moving part 52 to move along the second direction Y and towards... Figure 5When the moving part 52 moves to the right, the steering knuckles 60 on both sides rotate counterclockwise via the steering linkages 53 on both sides, causing the auxiliary wheels 40 on both sides of the floor brush 30 to rotate counterclockwise. That is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the left, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn to the left; Figure 6 As shown, when the user wants to control the brush 30 to turn right, the servo motor 511 drives the rudder arm 512 toward... Figure 6 When the rudder arm 512 rotates to the left, it drives the moving part 52 to move along the second direction Y and towards... Figure 6 When the moving part 52 moves to the left, the moving part 52 drives the steering knuckles 60 on both sides to rotate clockwise through the steering tie rods 53 on both sides, so that the auxiliary wheels 40 on both sides of the floor brush 30 rotate clockwise, that is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the right, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn to the right.

[0061] In one embodiment, one of the movable member 52 and the rudder arm 512 is provided with a first guide rod 513, and the other is provided with a first guide groove 521 extending in a direction perpendicular to the surface to be cleaned 10a. The first guide rod 513 is movably embedded in the first guide groove 521. When the rudder arm 512 drives the movable member 52 to move in the second direction Y, the first guide rod 513 moves synchronously along the first guide groove 521, so that the rotation of the rudder arm 512 can be converted into the movement of the movable member 52 in the second direction Y.

[0062] For example, Figure 4An exemplary illustration shows a first guide rod 513 disposed on the rudder arm 512 and a first guide groove 521 disposed on the movable member 52. When the rudder arm 512 rotates to one side in the second direction Y, the first guide rod 513 moves towards the bottom of the first guide groove 521 to guide the movable member 52 to move towards the same side in the second direction Y. When the user wants to control the ground brush 30 to turn left, the servo motor 511 drives the rudder arm 512 to rotate to the right side in the second direction Y, and the first guide rod 513 moves towards the bottom of the first guide groove 521 so that the rudder arm 512 drives the movable member 52 to move to the right side in the second direction Y. The movable member 52 drives the steering knuckles 60 on both sides to rotate counterclockwise through the steering tie rods 53 on both sides, so that the auxiliary wheels 40 on both sides of the ground brush 30 rotate counterclockwise, that is, the auxiliary wheels 40 on both sides of the ground brush 30 deflect to the left, and the auxiliary wheels 40 on both sides of the ground brush 30 can guide the ground brush 30 to turn left. When the user wants to control the ground brush 30 to turn right, the servo motor 511 drives the rudder arm 512 to rotate to the left in the second direction Y. The first guide rod 513 moves towards the bottom of the first guide groove 521 so that the rudder arm 512 drives the moving part 52 to move to the left in the second direction Y. The moving part 52 drives the steering knuckles 60 on both sides to rotate clockwise through the steering tie rods 53 on both sides, so that the auxiliary wheels 40 on both sides of the ground brush 30 rotate clockwise, that is, the auxiliary wheels 40 on both sides of the ground brush 30 deflect to the right. The auxiliary wheels 40 on both sides of the ground brush 30 can guide the ground brush 30 to turn right.

[0063] Of course, in other embodiments of this application, the first guide rod 513 may be disposed on the movable member 52 and the first guide groove 521 may be disposed on the rudder arm 512. In this way, when the rudder arm 512 rotates to one side in the second direction Y, the first guide rod 513 moves in the first guide groove 521 toward the top of the first guide groove 521 to guide the movable member 52 to move to the same side in the second direction Y. This is not limited here.

[0064] Furthermore, the moving part 52 can also approach the cleaning part 32 relative to the steering knuckle 60 in the first direction X. In this way, when the moving part 52 moves to the right along the second direction Y, the moving part 52 drives the steering knuckle 60 on both sides to rotate clockwise through the steering rods 53 on both sides, causing the auxiliary wheels 40 on both sides of the floor brush 30 to rotate clockwise, that is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the right, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn to the right; when the moving part 52 moves to the left along the second direction Y, the moving part 52 drives the steering knuckle 60 on both sides to rotate counterclockwise through the steering rods 53 on both sides, causing the auxiliary wheels 40 on both sides of the floor brush 30 to rotate counterclockwise, that is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the left, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn to the left.

[0065] In one embodiment, the end of the first guide rod 513 remote from the rudder arm 512 is further connected to a first baffle 514, which is configured to cooperate with the movable member 52 to restrict the first guide rod 513 from disengaging from the first guide groove 521. Figure 5 As shown, in the first direction X, the rudder arm 512 is located on the side of the movable member 52 closer to the cleaning member 32, and the first baffle 514 is located on the side of the movable member 52 away from the cleaning member 32. The first baffle 514 can abut against the movable member 52 around the first guide groove 521, thereby cooperating to restrict the first guide rod 513 from dislodging from the first guide groove 521.

[0066] Of course, in other embodiments of this application, the rudder arm 512 may be located on the side of the moving member 52 away from the cleaning member 32 in the first direction X, and the first baffle 514 may be located on the side of the moving member 52 close to the cleaning member 32. The first baffle 514 may abut against the moving member 52 around the first guide groove 521, thereby restricting the first guide rod 513 from dislodging from the first guide groove 521. This is not limited here.

[0067] In one embodiment, the drive assembly 50 further includes a mounting base 55, which is fixed to the brush body 31. Specifically, the mounting base 55 includes an upper body 551 and a lower body 552, which are joined together in a direction perpendicular to the surface 10a to be cleaned. A servo motor 511 is fixed to the mounting base 55.

[0068] The steering knuckle 60 is rotatably mounted on the fixed base 55. In the example described above, where the floor brush 30 has auxiliary wheels 40 on both sides in the second direction Y, the steering knuckles 60 connected to each auxiliary wheel 40 are distributed on both sides of the fixed base 55 in the second direction Y. The drive assembly 50 also includes a first rotating connector 541, through which the steering knuckle 60 is rotatably mounted on the fixed base 55. Optionally, the first rotating connector 541 may include a shaft and bearings. The shaft is embedded in the steering knuckle 60, and the upper body 551 and lower body 552 of the fixed base 55 are respectively fitted with bearings. The two ends of the shaft are connected to the bearings on the upper body 551 and lower body 552, respectively, to achieve a rotatable connection between the steering knuckle 60 and the fixed base 55.

[0069] The drive assembly 50 also includes a second rotary connector 542, through which both ends of the steering tie rod 53 are pivotally connected to the steering knuckle 60 and the moving member 52, respectively. Optionally, the second rotary connector 542 may include a double-ended screw and a nut, the double-ended screw extending in a direction perpendicular to the surface to be cleaned 10a, and both ends of the double-ended screw being secured by corresponding nuts. The pivotal connection between the steering tie rod 53 and the moving member 52 via the second rotary connector 542 allows the moving member 52 to move in the second direction Y, while restricting its movement in other directions.

[0070] Please refer to the following: Figure 7 , Figure 7 This is a structural schematic diagram of an embodiment of the steering tie rod of this application.

[0071] In one embodiment, the steering tie rod 53 includes a first tie rod portion 531, a second tie rod portion 532, and a third tie rod portion 533. The first tie rod portion 531 has a first end and a second end at opposite ends, respectively. The first end is pivotally connected to the moving member 52, and the second end is pivotally connected to the steering knuckle 60. The second tie rod portion 532 is connected to the first end, and the third tie rod portion 533 is connected to the second end. The ends of the second tie rod portion 532 and the third tie rod portion 533 are connected to each other at an angle. In other words, the first tie rod portion 531, the second tie rod portion 532, and the third tie rod portion 533 of the steering tie rod 53 form a stable, triangular-like structure, which helps to ensure the structural strength of the steering tie rod 53.

[0072] Please refer to the following: Figure 8 , Figure 8 This is a schematic diagram of the structure of an embodiment of the steering knuckle of this application.

[0073] In one embodiment, the steering knuckle 60 includes a first steering portion 61, a second steering portion 62, and a pivot portion 63. The pivot portion 63 is rotatably disposed on the brush body 31, and the axis of rotation of the pivot portion 63 relative to the brush body 31 is denoted as the first rotation axis O1. The first steering portion 61 is connected to the pivot portion 63 and is also pivotally connected to the moving member 52. The second steering portion 62 is connected to the pivot portion 63 and is also connected to the auxiliary wheel 40.

[0074] Please continue reading Figure 2 In one embodiment, the floor brush body 31 includes a first base 311, a second base 312, and a third base 313 sequentially distributed along the travel direction of the floor brush 30 (i.e., the first direction X), that is, the first base 311, the second base 312, and the third base 313 are sequentially distributed from front to back in the first direction X. A cleaning component 32 is disposed on the first base 311, the body 20 is connected to the second base 312, and at least a portion of the drive assembly 50 and the auxiliary wheel 40 are disposed on the third base 313.

[0075] In the above manner, the first base 311 and the second base 312 are equipped with a number of components. Compared with the case where the drive assembly 50 is disposed in the first base 311 or the second base 312, in this embodiment, at least a part of the drive assembly 50 and the auxiliary wheel 40 are disposed in the third base 313. The drive assembly 50 is disposed on the rear side of the auxiliary wheel 40, which can avoid the drive assembly 50 occupying the installation space of the first base 311 and the second base 312, which is beneficial to the layout and installation of the internal components of the floor brush 30.

[0076] Of course, in other embodiments of this application, the brush body 31 may include a first base 311 and a second base 312 distributed along the traveling direction of the brush 30, that is, the first base 311 and the second base 312 are distributed sequentially from front to back in the first direction X. The cleaning component 32 is disposed on the first base 311, and the body 20 is connected to the second base 312. At least a portion of the drive assembly 50 is disposed on the first base 311 and / or the second base 312. The cleaning device 10 has at least an inclined use state and a flat state. The angle between the body 20 and the surface 10a to be cleaned in the inclined use state is greater than the angle between the body 20 and the surface 10a to be cleaned in the flat state. Preferably, the body 20 is parallel to the surface 10a to be cleaned in the flat state. The drive assembly 50 is located on the front side of the auxiliary wheel 40, which eliminates the need for the third base 313 described in the previous embodiment. This allows the body 20 of the cleaning device 10 to lie as flat as possible when it is in a lying position, avoiding interference from the third base 313. Furthermore, the drive assembly 50 can be hidden inside the brush body 31 or located near the bottom of the brush body 31, minimizing any impact on the overall appearance of the brush 30.

[0077] In one embodiment, the cleaning device 10 further includes a caster wheel (not shown), which is disposed on the side of the floor brush body 31 facing the surface 10a to be cleaned. During the turning of the floor brush 30, the caster wheel can roll in the corresponding direction along with the floor brush 30. The turning radius of the caster wheel is always consistent with the turning radius of the floor brush 30, ensuring that the movement trajectory of the caster wheel remains parallel to the movement trajectory of the floor brush 30, thereby enabling the floor brush 30 to turn smoothly.

[0078] When the bottom of the floor brush 30 is equipped with a guide wheel that can only roll in one direction, the turning radius of the guide wheel will differ from that of the floor brush 30. This causes the movement trajectory of the guide wheel to interfere with the movement trajectory of the floor brush 30, resulting in the floor brush 30 getting stuck during turning or the floor brush 30 dragging the guide wheel, causing excessive wear on the guide wheel.

[0079] In one embodiment, the cleaning device 10 further includes a control element configured to receive control information input by a user, causing the drive assembly 50 to drive the steering knuckle 60 to rotate about a first rotation axis O1 according to the control information. For example, the control element may be a button for controlling the auxiliary wheel 40 to turn left or right, or a touch area on the cleaning device 10. The user inputs control information to control the auxiliary wheel 40 to turn left or right through the control element, causing the drive assembly 51 to drive the moving assembly 52 to move according to the control information, so that the moving assembly 52 drives the steering knuckle 60 to turn left or right, thereby driving the auxiliary wheel 40 to turn left or right.

[0080] In an alternative embodiment, the cleaning device 10 further includes a sensor configured to detect the angle of rotation of the body 20 about a second rotation axis O2, such that the drive assembly 50 drives the auxiliary wheel 40 to rotate about a first rotation axis O1 according to the angle detected by the sensor.

[0081] For example, in this embodiment, a sensor can detect whether the angle of rotation of the body 20 around the second rotation axis O2 reaches a preset angle threshold, and then determine whether to drive the auxiliary wheel 40 to rotate around the first rotation axis O1. For instance, when the sensor detects that the angle of rotation of the body 20 around the second rotation axis O2 reaches the preset angle threshold, the drive component 51 is controlled to drive the moving component 52 to move, so that the steering knuckle 60 can turn left or right through the moving component 52, thereby driving the auxiliary wheel 40 to turn left or right. When the sensor detects that the angle of rotation of the body 20 around the second rotation axis O2 does not reach the preset angle threshold, the central axis of the auxiliary wheel 40 is kept parallel to the second direction Y, that is, the auxiliary wheel 40 is not driven to rotate around the first rotation axis O1. Alternatively, in this embodiment, the sensor can also detect the angle of rotation of the body 20 around the second rotation axis O2 to drive the auxiliary wheel 40 to rotate around the first rotation axis O1 by a target angle, wherein the magnitude of the target angle is positively correlated with the magnitude of the angle of rotation of the body 20 around the second rotation axis O2, which is not limited here.

[0082] Please refer to the following: Figures 9 to 11 , Figure 9 This is a schematic diagram of the structure of the second embodiment of the cleaning device of this application. Figure 10 This is a schematic diagram of the structure of one embodiment of the driving component in the fuselage of this application. Figure 11 yes Figure 9 A schematic diagram of the drive assembly of the cleaning device shown.

[0083] In an alternative embodiment, the fuselage 20 has a second rotation axis O2 extending along it, and is configured to rotate about the second rotation axis O2. This embodiment differs from the previous one in that a drive member 51 is disposed on the fuselage 20 and is configured to rotate synchronously with the fuselage 20 to drive the moving member 52 to move along the second direction Y.

[0084] When the fuselage 20 rotates around the second rotation axis O2, the drive component 51 rotates synchronously with the fuselage 20 around the second rotation axis O2. For example... Figure 12 As shown, when the user wants to control the brush 30 to turn left, the user controls the body 20 to rotate left around the second rotation axis O2. The drive component 51 rotates synchronously with the body 20 to drive the moving component 52 along the second direction Y and towards... Figure 12 When the moving part 52 moves to the right, the steering knuckles 60 on both sides rotate counterclockwise via the steering linkages 53 on both sides, causing the auxiliary wheels 40 on both sides of the floor brush 30 to rotate counterclockwise. That is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the left, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn to the left; Figure 13 As shown, when the user wants to control the brush 30 to turn right, the user controls the body 20 to rotate around the second rotation axis O2 and to the right. The drive component 51 rotates synchronously with the body 20 to drive the moving component 52 along the second direction Y and towards Figure 13 When the moving part 52 moves to the left, the moving part 52 drives the steering knuckles 60 on both sides to rotate clockwise through the steering tie rods 53 on both sides, so that the auxiliary wheels 40 on both sides of the floor brush 30 rotate clockwise, that is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the right, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn to the right.

[0085] The body 20 also has a third rotation axis O3 parallel to the second direction Y, and the body 20 is configured to rotate relative to the brush 30 about the third rotation axis O3. In the example described above where the cleaning device 10 has an inclined use state and a lying-flat state, the body 20 rotates relative to the brush 30 about the third rotation axis O3, allowing the cleaning device 10 to switch between the inclined use state and the lying-flat state. One of the drive member 51 and the moving member 52 is provided with a second guide rod 515, and the other is provided with a second guide groove 522 extending circumferentially along the third rotation axis O3. The second guide rod 515 is movably embedded in the second guide groove 522. The drive member 51, through the cooperation of the second guide rod 515 and the second guide groove 522, can drive the moving member 52 to move along the second direction Y. The design of the second guide groove 522 extending circumferentially along the third rotation axis O3 allows the body 20 to rotate relative to the brush 30 about the third rotation axis O3, thereby allowing the cleaning device 10 to switch between the inclined use state and the lying-flat state.

[0086] Furthermore, a second baffle 516 is connected to the end of the second guide rod 515 away from the drive member 51. The second guide rod 515 passes through the second guide groove 522, and the drive member 51 and the second baffle 516 are respectively located on both sides of the second guide groove 522 in the second direction Y. The second baffle 516 is configured to cooperate with the moving member 52 to restrict the second guide rod 515 from disengaging from the second guide groove 522.

[0087] For example, the driving member 51 is provided with a second guide rod 515, and the moving member 52 is provided with a second guide groove 522. A second baffle 516 abuts against the moving member 52 surrounding the second guide groove 522, thereby preventing the second guide rod 515 from disengaging from the second guide groove 522. The driving member 51 has second guide rods 515 on both sides in the second direction Y, and the ends of each second guide rod 515 away from the driving member 51 are connected to the second baffle 516. The driving member 51 has second guide grooves 522 on both sides in the second direction Y, and each second guide rod 515 passes through the corresponding second guide groove 522.

[0088] like Figure 12 As shown, when the user wants to control the brush 30 to turn left, the user controls the body 20 to rotate around the second rotation axis O2 and to the left. The drive component 51 rotates synchronously with the body 20. The drive component 51 and / or the second baffle 516 on the left side of the drive component 51 drive the moving component 52 to move along the second direction Y and towards Figure 12 When the moving part 52 moves to the right, the steering knuckles 60 on both sides rotate counterclockwise via the steering linkages 53 on both sides, causing the auxiliary wheels 40 on both sides of the floor brush 30 to rotate counterclockwise. That is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the left, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn to the left; Figure 13 As shown, when the user wants to control the brush 30 to turn right, the user controls the body 20 to rotate around the second rotation axis O2 and to the right. The drive component 51 rotates synchronously with the body 20. The drive component 51 and / or the second baffle 516 on the right side of the drive component 51 drive the moving component 52 to move along the second direction Y and towards Figure 13 When the moving part 52 moves to the left, the moving part 52 drives the steering knuckles 60 on both sides to rotate clockwise through the steering tie rods 53 on both sides, so that the auxiliary wheels 40 on both sides of the floor brush 30 rotate clockwise, that is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the right, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn to the right.

[0089] In an alternative embodiment, this embodiment differs from the above embodiment in that auxiliary wheels 40 and steering knuckles 60 (not shown) are respectively provided on opposite sides of the brush body 31. The drive assembly 50 includes at least two drive members 51, each drive member 51 being connected to a different auxiliary wheel 40 via a different steering knuckle 60. The drive member 51 is configured to drive the steering knuckle 60 to which it is connected to rotate around the first rotation axis O1.

[0090] When the user wants to control the floor brush 30 to turn left, each drive component 51 drives its connected steering knuckle 60 to rotate counterclockwise, causing the auxiliary wheels 40 on both sides of the floor brush 30 to rotate counterclockwise, that is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the left, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn left; when the user wants to control the floor brush 30 to turn right, each drive component 51 drives its connected steering knuckle 60 to rotate clockwise, causing the auxiliary wheels 40 on both sides of the floor brush 30 to rotate clockwise, that is, the auxiliary wheels 40 on both sides of the floor brush 30 deflect to the right, and the auxiliary wheels 40 on both sides of the floor brush 30 can guide the floor brush 30 to turn right.
