Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, specifically to a cleaning device; this disclosure also relates to a cleaning equipment. Background Technology

[0002] With the development of social productivity, people's living standards have also improved. With basic material needs met, people have begun to utilize various tools to reduce labor and improve their quality of life, leading to the emergence of household cleaning equipment. However, cleaning robots on the market often struggle to achieve zero-distance contact with walls when working close to them, resulting in cleaning blind spots. To solve this problem, side brushes extending beyond the machine's edge can be added to increase the cleaning range, thus achieving thorough cleaning.

[0003] However, in existing technologies, the side brushes on cleaning equipment do not have a lifting function. When there are oil or water stains on the ground, the side brush will come into contact with the oil or water stains, causing the dirt to be smeared onto the clean floor; or when the cleaning equipment sweeps on a carpet, the side brush will come into contact with the carpet, thereby increasing the resistance of the side brush and affecting its lifespan. Utility Model Content

[0009] In one embodiment of this disclosure, a drive shaft is further included, the drive shaft being configured to connect the housing and the base, the drive shaft being configured to drive the cleaning unit to rotate relative to the housing.

[0010] In one embodiment of this disclosure, the transmission unit includes a one-way transmission member connected to the housing and configured to rotate relative to the housing only in a first direction; one end of the one-way transmission member extending into the base is configured to engage in transmission with the cleaning component.

[0011] In one embodiment of this disclosure, the one-way transmission component includes a reversing shaft coaxially disposed with the drive shaft, the reversing shaft being rotatably connected to the housing via a one-way bearing and configured to rotate relative to the housing only in a first direction;

[0012] The reversing shaft is provided with a first mating part, and the cleaning component is provided with a second mating part; the first mating part and the second mating part are connected in a driving connection.

[0013] In one embodiment of this disclosure, the first mating part is a gear disk disposed on the reversing shaft, and the second mating part is a meshing gear disposed on the cleaning component and engaging with the gear disk in a transmission manner.

[0014] In one embodiment of this disclosure, the reversing shaft is fixedly connected to a protrusion, and the base is provided with at least two limiting members. The protrusion is configured to be limited between any two limiting members, and when the transmission unit rotates relative to the base, the protrusion moves between the two limiting members.

[0015] In one embodiment of this disclosure, the first mating part is a flange disposed on the reversing shaft, and the second mating part is a first abutting part and a second abutting part disposed on the cleaning component. The first abutting part and the second abutting part are configured to have a predetermined included angle, and the flange is configured to restrict movement between the first abutting part and the second abutting part.

[0016] In one embodiment of this disclosure, an arc-shaped groove is formed at the location where the first abutting portion and the second abutting portion are connected.

[0017] In one embodiment of this disclosure, the base includes an upper cover, a lower cover, and a cavity enclosed by the upper cover and the lower cover, and the reversing shaft is configured to be rotatably connected within the cavity.

[0018] In one embodiment of this disclosure, the reversing shaft has a hollow cavity, and the lower end of the drive shaft is configured to pass through the hollow cavity and bond to the base.

[0019] According to a second aspect of this disclosure, a cleaning apparatus is also provided, comprising:

[0020] case;

[0021] A cleaning unit is configured to rotate on the housing; the cleaning unit includes a base and a cleaning component, the cleaning component being rotatably connected to the base and configured to move between a first position and a second position; in the first position, the cleaning component is configured to extend from the base in the height direction to contact the working surface; in the second position, the cleaning component is configured to rotate away from the working surface; a meshing gear is provided on the cleaning component;

When the cleaning component is in the first position, it contacts the working surface; when it is in the second position, it detaches from the working surface. The cleaning device can be a side brush, and the cleaning component can be the bristles of the side brush. During normal cleaning operations, the cleaning component can remain in the first position, thus contacting and cleaning the working surface. When there is oil or water on the working surface to be cleaned, the cleaning component can be controlled to move to the second position in advance, thereby detaching from the working surface early and preventing the cleaning component from being contaminated by liquid dirt or carrying dirt to other locations. Furthermore, when the working surface to be cleaned is a carpet (or other working surface with a high coefficient of friction), the cleaning component can also be controlled to move to the second position in advance, thus avoiding excessive rotational resistance and extending the service life of the cleaning unit.

[0041] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0042] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0043] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0045] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0046] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0047] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0048] This disclosure provides a cleaning apparatus and a cleaning device. To keep the text concise, the cleaning apparatus will be described in conjunction with the description of the cleaning device, and will not be described separately.

[0049] This disclosure provides a cleaning device, which includes a main body and a cleaning device. The cleaning device can be a handheld cleaning device, such as a handheld cleaning machine, handheld vacuum cleaner, handheld floor scrubber, handheld fabric cleaning machine, or other handheld cleaning devices well known to those skilled in the art. It can also be a sweeping robot, mopping robot, sweeping and mopping robot, or other self-moving cleaning devices used to clean work surfaces such as floors, sofas, and carpets that require cleaning.

[0050] In this embodiment, taking a robotic vacuum cleaner as an example, the main body of the device can be equipped with a walking component, which is used to move the cleaning device on the work surface. A suction port can be provided on the bottom surface of the main body for vacuuming and cleaning the work surface. The suction port is usually located in the middle area of ​​the main body and within the projection range of the main body onto the work surface. When the cleaning device works close to a wall, it is usually difficult for the main body to achieve zero-distance contact with the edge, resulting in cleaning dead corners. The cleaning device on the cleaning device of this disclosure can be used to solve the above problems.

[0051] In one embodiment of this disclosure, the cleaning device is a side brush. Taking the direction of travel of the cleaning device as the front, the side brush can be installed at the bottom front edge of the device body. The bristles of the side brush can extend beyond the projection range of the device body on the working surface, thereby filling the gap between the suction port and the wall when the cleaning device is working close to the wall, cleaning hard-to-reach areas, and achieving thorough cleaning. During normal operation, the side brush can rotate relative to the device body, and its bristles can sweep dust from the walls and corners to areas within the suction range of the suction port for thorough cleaning.

[0052] refer to Figures 1 to 3 The cleaning device provided in this disclosure includes: a housing 1, a cleaning unit 2, and a transmission unit. The cleaning unit 2 is configured to rotate on the housing 1, and during rotation, it cleans the working surface. The cleaning unit 2 includes a base 21 and cleaning components 22, which are rotatably connected to the base 21. Preferably, multiple cleaning components 22 are provided, and the multiple cleaning components 22 are distributed in the circumferential direction of the base 21. Alternatively, only one cleaning component 22 may be provided; this disclosure does not specifically limit the specific number or distribution of the cleaning components 22. (Reference) Figure 4 and Figure 5 Multiple rotating grooves 24 are provided on the side of the base 21, and the cleaning component 22 is rotatably connected to the base 21 through the rotating grooves 24. The position on the cleaning component 22 that mates with the rotating groove 24 is constructed as a cylindrical rotating part 221. Under the action of external force, the rotating part 221 can rotate in the rotating groove 24, thereby allowing the cleaning component 22 to rotate relative to the base 21.

[0053] In the case where the cleaning device is a side brush, the cleaning element 22 is the bristles of the side brush, which can be bristles with a certain degree of hardness or soft rubber. In a specific embodiment of this disclosure, the cleaning elements 22 distributed in the circumferential direction of the base 21 are constructed in a conical shape, wherein the apex of the cone is the location of the base 21. The fixed ends of multiple clusters of cleaning elements 22 are fixedly connected to the main body, and the free ends extend freely outward. The taper of the cleaning elements 22 gradually decreases from the fixed end to the free end, and the free ends spread out on the working surface, thereby forming an annular cleaning surface. By setting the cleaning elements 22 to a conical shape, the base 21 of the cleaning unit 2 will not directly contact the working surface. Only the soft cleaning elements 22 can contact the working surface, thereby avoiding the base 21 from scratching or damaging the working surface.

[0054] refer to Figure 1 and Figure 2 The cleaning component 22 can move between the first position and the second position, such as... Figure 1As shown, when in the first position, the cleaning component 22 is configured to extend from the base 21 in the height direction to contact the working surface. During normal cleaning operations, the cleaning component 22 can remain in the first position, thereby contacting and cleaning the working surface.

[0055] like Figure 2 As shown, in the second position, the cleaning component 22 is configured to rotate away from the working surface. At this time, the cleaning component 22 rotates relative to the base 21 to a flipped-up state, thus preventing the cleaning component 22 from contacting the working surface. When there is oil or water on the working surface to be cleaned, the cleaning component 22 can be controlled to move to the second position in advance, thereby detaching from the working surface and preventing the cleaning component 22 from being contaminated by liquid dirt or carrying dirt to other locations. Furthermore, when the working surface to be cleaned is a carpet (or other working surface with a high coefficient of friction), the cleaning component 22 can also be controlled to move to the second position in advance, thus avoiding excessive rotational resistance and extending the service life of the cleaning unit 2.

[0056] The cleaning unit 2 of this disclosure is driven by a transmission unit, thereby enabling the cleaning unit 2 to rotate relative to the housing 1 and allowing the cleaning component 22 to move between a first position and a second position. Specifically, as shown... Figure 1 As shown, the transmission unit is configured to be controlled by the drive unit to move the cleaning component 22 to the first position when the drive unit rotates in the first direction X1, as... Figure 2 As shown, the transmission unit is configured to move the cleaning component 22 to the second position when the drive unit rotates in the second direction X2. (Referring to...) Figures 1 to 3 The drive unit may include a motor 31 and a reduction gearbox 32 that is drively connected to the motor 31. The driving force output by the motor 31 is transmitted to the transmission unit through the reduction gearbox 32, thereby driving the cleaning unit 2 to move. In a specific embodiment of this disclosure, the housing 1 may include a portion of the housing of the reduction gearbox 32.

[0057] Furthermore, the cleaning device also includes a drive shaft 4, which is configured to connect the housing 1 and the base 21, and is configured to drive the cleaning unit 2 to rotate relative to the housing 1. (Reference) Figure 3 In its view direction, the upper end of the drive shaft 4 is connected to the output shaft of the reduction gearbox 32, and the lower end of the drive shaft 4 is connected to the base 21. When the drive unit is working, the drive shaft 4 drives the base 21 to rotate together. By controlling the output power signal of the motor 31, the drive shaft 4 is controlled to drive the base 21 to rotate along the first direction X1 or the second direction X2, thereby controlling the movement of the cleaning component 22 between the first position and the second position.

[0058] The transmission unit includes a one-way transmission component connected to the housing 1 and configured to rotate relative to the housing 1 only in a first direction X1. Specifically, the one-way transmission component includes a reversing shaft 5 coaxially arranged with the drive shaft 4. The reversing shaft 5 is rotatably connected to the housing 1 via a one-way bearing 7 and is configured to rotate relative to the housing 1 only in the first direction X1. (Reference) Figures 3 to 5 The base 21 includes an upper cover 211, a lower cover 212, and a cavity formed by the upper cover 211 and the lower cover 212. The reversing shaft 5 is configured to be rotatably connected in the cavity, and one end of the reversing shaft 5 is configured to pass through the upper cover 211.

[0059] One end of the reversing shaft 5 extends into the base 21. Specifically, the end of the one-way transmission component extending into the base 21 is configured to engage with the cleaning component 22. The cavity formed by the upper cover 211 and the lower cover 212 provides space for the transmission installation of the reversing shaft 5 and the cleaning component 22. When the drive shaft 4 drives the cleaning unit 2 to rotate, the cleaning component 22 can apply a corresponding rotational force to the reversing shaft 5. Figure 5 As shown, a through hole 25 for the reversing shaft 5 to pass through can be provided on the upper cover 211. The through hole 25 can be constructed as a circle. The position where the reversing shaft 5 mates with the through hole 25 can be constructed as a cylinder, so that the reversing shaft 5 can rotate relative to the upper cover 211.

[0060] The other end of the reversing shaft 5 extends into the housing 1 and is rotatably connected to the housing 1 via a one-way bearing 7 located between the housing 1 and the reversing shaft 5. Under the restriction of the one-way bearing 7, the reversing shaft 5 can only rotate in the first direction X1. When it is subjected to a force that rotates in the second direction X2, the reversing shaft 5 will be locked by the one-way bearing 7 and cannot rotate in the second direction X2.

[0061] In one specific embodiment of this disclosure, such as Figure 4 As shown, the reversing shaft 5 has a hollow cavity 53, and the lower end of the drive shaft 4 is configured to pass through the hollow cavity 53 and be bonded to the base 21. Specifically, as... Figure 5 As shown, a connecting groove 23 can be provided on the bottom wall of the lower cover 212 of the base 21. The lower end of the drive shaft 4 extends into the connecting groove 23 and is keyed to it. Both the connecting groove 23 and the lower end of the drive shaft 4 are constructed in a non-circular shape, for example, a hexagon, so that the drive shaft 4 always maintains engagement with the inner wall of the connecting groove 23 during rotation, thereby driving the base 21 to rotate together. Furthermore, the hollow cavity 53 in the reversing shaft 5 can be constructed as a cylindrical cavity. The drive shaft 4 passes through the hollow cavity 53 and does not contact the inner wall of the hollow cavity 53 during rotation, thus not directly applying rotational force to the reversing shaft 5.

[0062] Under normal operating conditions, the cleaning component 22 is located in the first position and is configured to drive the one-way transmission component to rotate freely in the first direction X1 as the base 21 rotates in the first direction X1. At this time, the drive shaft 4 rotates along the first direction X1 under the action of the drive unit, and drives the base 21 and the cleaning component 22 to rotate in the first direction X1; the reversing shaft 5 is subjected to the transmission force of the cleaning component 22, and it is not subject to the locking force of the one-way bearing 7 in the first direction X1, so it can rotate together with the cleaning component 22 in the first direction X1.

[0063] When it is necessary to control the cleaning component 22 to move to the second position, the cleaning component 22 in the first position is configured to move relative to the base 21 towards the second position under the locking force of the one-way transmission component in the second direction X2 as it rotates with the base 21 in the second direction X2. At this time, the drive shaft 4 rotates along the second direction X2 under the action of the drive unit, and drives the base 21 and the cleaning component 22 to rotate along the second direction X2; the reversing shaft 5 is subjected to the transmission force of the cleaning component 22. Since it is subject to the locking force of the one-way bearing 7 in the second direction X2, the reversing shaft 5 cannot rotate along the second direction X2, and it will apply a reverse force to the cleaning component 22, thereby causing the cleaning component 22 to rotate relative to the base 21, and thus move to the second position.

[0064] When it is necessary to control the cleaning component 22 to move back to the first position, the cleaning component 22 in the second position is configured to move relative to the base 21 toward the first position under the rotational resistance of the one-way transmission component during the rotation of the base 21 in the first direction X1, and when the cleaning component 22 is in the first position, the cleaning component 22 drives the one-way transmission component to overcome its rotational resistance and rotate relative to the housing 1. At this time, the drive shaft 4 rotates along the first direction X1 under the action of the drive unit, and drives the base 21 and the cleaning component 22 to rotate along the first direction X1. The reversing shaft 5 is subjected to the transmission force of the cleaning component 22. Since the rotational resistance between it and the base 21 is greater than the transmission force applied by the cleaning component 22, the reversing shaft 5 will not immediately follow the rotation of the cleaning component 22, but will apply a force in the opposite direction to the cleaning component 22, thereby causing the cleaning component 22 to rotate relative to the base 21, and thus move to the first position. The cleaning component 22, which has moved back to the first position, continues to transmit rotational force to the reversing shaft 5 until it overcomes the resistance, thereby enabling the reversing shaft 5 to rotate along the first direction X1 with the cleaning component 22.

[0065] In one embodiment of this disclosure, reference is made to Figure 3 and Figure 4The inner ring of the one-way bearing 7 is provided with a bushing 8, and one end of the reversing shaft 5 that protrudes from the upper cover 211 is configured to be keyed to the bushing 8. The bushing 8 is disposed between the reversing shaft 5 and the one-way bearing 7, and the sleeve hole of the bushing 8 is configured to fit the upper end of the reversing shaft 5. Both the sleeve hole of the bushing 8 and the upper end of the reversing shaft 5 are configured to be non-circular, for example, hexagonal, so that relative rotation does not occur between the reversing shaft 5 and the bushing 8.

[0066] This disclosure allows the cleaning unit 2 to be detachably connected to the housing 1 via the reversing shaft 5 by providing a bushing 8. When the cleaning unit 2 and the reversing shaft 5 are removed, the one-way bearing 7 remains between the bushing 8 and the housing 1 and will not fall off. During installation, the user needs to insert the upper end of the reversing shaft 5 into the bushing 8, and simultaneously insert the drive shaft 4 through the hollow cavity 53 of the reversing shaft 5 and into the connecting groove 23 at the bottom of the base 21. The base and drive shaft 4 are then fixed together using fasteners such as screws 9. By providing a detachably connected cleaning unit 2, the user's replacement cost is reduced. After a period of use, the user does not need to replace the entire cleaning device, but can replace only the severely worn cleaning unit 2.

[0067] In one embodiment of this disclosure, a limiting mechanism is provided between the reversing shaft 5 and the base 21. The limiting mechanism is configured to limit the relative rotation angle of the reversing shaft 5 relative to the base 21 in a first direction X1 and a second direction X2. It is understood that the reversing shaft 5 can move relative to the base 21, thereby driving the cleaning component 22 to move between a first position and a second position. The cleaning component 22 should not continue to rotate after switching to the correct position. Therefore, this disclosure provides a limiting mechanism, which prevents the reversing shaft 5 from rotating further relative to the base 21, thus preventing further rotation of the cleaning component 22. The cleaning component 22 can remain in the first or second position.

[0068] In one specific embodiment of this disclosure, reference is made to Figure 5 and Figure 9 A protrusion 54 is fixedly connected to the reversing shaft 5, and at least two limiting members 26 are provided on the base 21. The protrusion 54 and the limiting members 26 together constitute the aforementioned limiting mechanism. The protrusion 54 is configured to be confined between any two limiting members 26, and when the transmission unit rotates relative to the base 21, the protrusion 54 moves between the two limiting members 26. The protrusion 54 may protrude from the bottom surface of the reversing shaft 5, and the limiting members 26 may be provided on the lower cover 212 of the base 21, such as... Figure 5As shown, in this embodiment, three limiting members 26 are provided, and the three limiting members 26 are evenly spaced along the circumferential direction. The protrusion 54 is located between two of the limiting members 26. When the reversing shaft 5 rotates relative to the base 21, the protrusion 54 can move within the gap between the two limiting members 26. When it moves to the limit position, the side wall of the protrusion 54 abuts against the side wall of the limiting member 26, thereby restricting the reversing shaft 5 and the base 21 from continuing to move relative to each other in the current rotation direction.

[0069] When the cleaning component 22 reaches the first position, the reversing shaft 5 cannot continue to rotate relative to the base 21 under the restriction of the limiting mechanism. At this time, the cleaning component 22 can drive the reversing shaft 5 to rotate freely in the first direction X1. When the cleaning component 22 reaches the second position, the reversing shaft 5 cannot continue to rotate relative to the base 21 under the restriction of the limiting mechanism. At this time, the reversing shaft 5 transmits rotational resistance to the cleaning component 22, the base 21, the drive shaft 4, and the drive unit in sequence, and the current of the motor 31 increases accordingly. When the current increases to a value greater than the threshold, the control unit can determine that the cleaning component 22 has reached the second position, so there is no need to continue to output the driving force for rotation in the second direction X2.

[0070] In one embodiment of this disclosure, a first mating portion is provided on the reversing shaft 5, and a second mating portion is provided on the cleaning component 22; the first mating portion and the second mating portion are connected in a transmission manner. When the drive shaft 4 starts to drive the base 21 and the cleaning component 22 to rotate synchronously, the reversing shaft 5 remains stationary under the action of resistance, thus causing relative movement between the first mating portion and the second mating portion. The first mating portion is located at the end of the reversing shaft 5 that extends into the base 21, and the second mating portion is located at the end of the cleaning component 22 that extends into the base 21. The transmission connection between the first and second mating portions realizes the transmission connection between the cleaning component 22 and the reversing shaft 5.

[0071] This disclosure provides the following two specific structures for the first and second mating parts, and describes their specific transmission forms. It should be noted that the two embodiments provided in this disclosure are merely examples; in addition to the following two specific embodiments, the first and second mating parts can also be arranged in other ways, and this disclosure does not limit their application.

[0072] In one specific embodiment of this disclosure, reference is made to Figure 5 and Figure 6The first mating part is a gear disk 51 mounted on the reversing shaft 5, and the second mating part is a meshing gear 61 mounted on the cleaning component 22 and drivingly meshing with the gear disk 51. The meshing gear 61 is configured to tend to drive the gear disk 51 in the same direction during its revolution around the drive shaft 4. Specifically, the gear disk 51 is located at the lower end of the reversing shaft 5, and the meshing gear 61 is constructed to be fixed to one end of the cleaning component 22 within the base 21, with the rotation axis of the gear disk 51 configured to be perpendicular to the rotation axis of the meshing gear 61. Figure 5 As shown, during the rotation of the cleaning component 22 along the first direction X1, the meshing gear 61 tends to rotate in the third direction X3 due to its interaction with the gear disk 51; during the rotation of the cleaning component 22 along the second direction X2, the meshing gear 61 tends to rotate in the fourth direction X4 due to its interaction with the gear disk 51.

[0073] refer to Figure 6 When it is necessary to control the cleaning component 22 to move from the first position to the second position, the drive shaft 4 rotates along the second direction X2 under the action of the drive unit, and drives the base 21 and the cleaning component 22 to rotate along the second direction X2. At this time, the meshing gear 61 has a tendency to rotate in the fourth direction X4 due to its interaction with the gear disk 51. The reversing shaft 5 is driven by the force transmitted by the cleaning component 22, and therefore has a tendency to rotate in the second direction X2. Because it is locked by the one-way bearing 7 in the second direction X2, the reversing shaft 5 cannot rotate in the second direction X2, and can apply a force to the meshing gear 61 through the gear disk 51. The meshing gear 61 rotates in the fourth direction X4, and drives the cleaning component 22 to rotate in the fourth direction X4 relative to the base 21, thereby moving to the second position.

[0074] refer to Figure 5 When it is necessary to control the cleaning component 22 to move back to the first position, the drive shaft 4 rotates along the first direction X1 under the action of the drive unit, and drives the base 21 and the cleaning component 22 to rotate along the first direction X1. At this time, the meshing gear 61 has a tendency to rotate in the third direction X3 due to its interaction with the gear disk 51. The reversing shaft 5 is transmitted by the cleaning component 22, so it has a tendency to rotate in the first direction X1. The reversing shaft 5 is transmitted by the cleaning component 22. Since the rotational resistance between it and the base 21 is greater than the transmission force applied by the cleaning component 22, the reversing shaft 5 will not immediately follow the cleaning component 22 to rotate, but will apply a force in the opposite direction to the cleaning component 22. The meshing gear 61 rotates in the third direction X3, and drives the cleaning component 22 to rotate in the third direction X3 relative to the base 21, thereby moving to the first position. The cleaning component 22, which has moved back to the first position, continues to transmit rotational force to the reversing shaft 5 until it overcomes the resistance, thereby enabling the reversing shaft 5 to rotate along the first direction X1 with the cleaning component 22.

[0075] In another specific embodiment of this disclosure, reference is made to Figure 7 and Figure 8 The first mating part is a flange 52 provided on the reversing shaft 5, and the second mating part is a first abutment part 621 and a second abutment part 622 provided on the cleaning component 22. The first abutment part 621 and the second abutment part 622 are configured to have a predetermined included angle, and the flange 52 is configured to restrict movement between the first abutment part 621 and the second abutment part 622. Preferably, the extending directions of the first abutment part 621 and the second abutment part 622 can be perpendicular to each other, and the first abutment part 621 and the second abutment part 622 are integrally formed swing rods.

[0076] Specifically, such as Figure 8 As shown, an arcuate groove 623 is formed at the junction of the first abutment portion 621 and the second abutment portion 622, and the flange 52 is configured to be confined within the arcuate groove 623. During the rotation of the cleaning member 22 along the first direction X1, the flange 52 abuts against the first abutment portion 621 and applies force to it; during the rotation of the cleaning member 22 along the second direction X2, the flange 52 abuts against the second abutment portion 622 and applies force to it. As the cleaning member 22 rotates between the first and second positions, the flange 52 slides within the arcuate groove 623, thereby switching between abutting against the first abutment portion 621 and the second abutment portion 622.

[0077] When it is necessary to control the cleaning component 22 to move from the first position to the second position, the drive shaft 4 rotates along the second direction X2 under the action of the drive unit, and drives the base 21 and the cleaning component 22 to rotate along the second direction X2. At this time, the second abutment portion 622 abuts against the flange 52, and the reversing shaft 5 is subjected to the transmission force of the cleaning component 22, so it has a tendency to rotate in the second direction X2. Because it is subjected to the locking force of the one-way bearing 7 in the second direction X2, the reversing shaft 5 cannot rotate in the second direction X2, and can apply force to the second abutment portion 622 through the flange 52. The second abutment portion 622 drives the cleaning component 22 to rotate relative to the base 21 to the second position.

[0078] When it is necessary to control the cleaning component 22 to move back to the first position, the drive shaft 4 rotates along the first direction X1 under the action of the drive unit, and drives the base 21 and the cleaning component 22 to rotate along the first direction X1. At this time, the first abutment part 621 abuts against the flange 52, and the reversing shaft 5 is subjected to the transmission force of the cleaning component 22, so it has a tendency to rotate in the first direction X1. The reversing shaft 5 is subjected to the transmission force of the cleaning component 22. Since the rotational resistance between the reversing shaft 5 and the base 21 is greater than the transmission force applied by the cleaning component 22, the reversing shaft 5 will not immediately follow the rotation of the cleaning component 22, but will apply a force in the opposite direction to the cleaning component 22. The first abutment part 621 drives the cleaning component 22 to rotate relative to the base 21 to the first position. The cleaning component 22, which has moved back to the first position, continues to transmit rotational force to the reversing shaft 5 through the first abutment part 621 until the resistance is overcome, thereby enabling the reversing shaft 5 to rotate along the first direction X1 with the cleaning component 22.

[0079] This disclosure also provides a cleaning device, including: a housing 1, a cleaning unit 2, and a transmission unit. The cleaning unit 2 is configured to rotate on the housing 1. The cleaning unit 2 includes a base 21 and a cleaning component 22. The cleaning component 22 is rotatably connected to the base 21 and configured to move between a first position and a second position. In the first position, the cleaning component 22 is configured to extend from the base 21 in the height direction to contact a working surface. In the second position, the cleaning component 22 is configured to rotate away from the working surface. A meshing gear 61 is provided on the cleaning component 22. The transmission unit is provided with a gear disk 51 that meshes with the meshing gear 61. The gear disk 51 is configured to drive the cleaning component 22 to the first position when rotating in a first direction, and to drive the cleaning component 22 to the second position when rotating in a second direction.

[0080] Application scenarios

[0081] In home cleaning scenarios, the cleaning device is a robotic vacuum cleaner, with a side brush installed on the bottom front edge of the main body of the robotic vacuum cleaner. The cleaning components 22 of the side brush can extend beyond the projection range of the main body of the device on the working surface, thereby filling gaps when the robotic vacuum cleaner works close to the wall and achieving thorough cleaning.

[0082] In a normal cleaning scenario, the drive unit simply drives the drive shaft 4 to rotate along the first direction X1, thereby driving the cleaning component 22 to rotate while maintaining it in the first position in contact with the ground, thus cleaning the ground. Specifically, the drive shaft 4 rotates along the first direction X1 under the action of the drive unit, driving the base 21 and the cleaning component 22 to rotate along the first direction X1; the reversing shaft 5 is driven by the force transmitted by the cleaning component 22, and it is not subject to the locking force of the one-way bearing 7 in the first direction X1, thus it can rotate along the first direction X1 with the cleaning component 22.

[0083] When the cleaning surface changes to a carpet, the cleaning component 22 needs to be moved to a second position away from the working surface in advance to prevent wear on the cleaning component 22 and extend the service life of the side brush. Specifically, the drive shaft 4 rotates along the second direction X2 under the action of the drive unit, and drives the base 21 and the cleaning component 22 to rotate along the second direction X2; the reversing shaft 5 is driven by the force transmitted by the cleaning component 22. Since it is locked by the one-way bearing 7 in the second direction X2, the reversing shaft 5 cannot rotate along the second direction X2, and it will apply a force in the opposite direction to the cleaning component 22, thereby causing the cleaning component 22 to rotate relative to the base 21, and thus move to the second position.

[0084] After the robot vacuum cleaner finishes cleaning the carpet and moves to a normal floor, the cleaning component 22 can be controlled to move back to the first position, allowing the side brush to continue cleaning. Specifically, the drive shaft 4 rotates along the first direction X1 under the action of the drive unit, driving the base 21 and the cleaning component 22 to rotate along the first direction X1. The reversing shaft 5 is subjected to the power transmitted by the cleaning component 22. Since the rotational resistance between it and the base 21 is greater than the power transmitted by the cleaning component 22, the reversing shaft 5 will not immediately follow the cleaning component 22 to rotate. Instead, it will apply a force in the opposite direction to the cleaning component 22, causing the cleaning component 22 to rotate relative to the base 21 and move to the first position. The cleaning component 22, which has moved back to the first position, continues to transmit rotational power to the reversing shaft 5 until it overcomes the resistance, thereby enabling the reversing shaft 5 to rotate along the first direction X1 with the cleaning component 22.
