Abstract

A cleaning mechanism (100) and a cleaning device. The cleaning mechanism (100) comprises a base (1) and a cleaning assembly (2). The cleaning assembly (2) is arranged on the base (1), and comprises a cleaning member (21) rotatably arranged on the base (1), wherein the cleaning member (21) extends transversely along the base (1); and under the action of a driving force, at least one end of the cleaning member (21) in the transverse direction thereof may at least partially extend out of the base (1). When the cleaning mechanism (100) is cleaning normally, the cleaning member (21) may perform cleaning at a first position where normal sweeping is performed. When the cleaning mechanism (100) cleans an edge area, such as a wall corner area, one end of the cleaning member (21) may be driven to extend out of the base (1), such that the cleaning member (21) may be better attached to the edge of a wall corner for cleaning. Since, the cleaning mechanism (100) does not have a cleaning blind area, the cleaning effect on edge areas such as the wall corners, is better, such that the user experience is also better.

[0023] The technical solutions in the present disclosure will be described clearly and completely below with reference to the drawings; obviously, the described embodiments are some of, rather than all of, the embodiments of the present disclosure. The present disclosure is described in detail below with reference to the accompanying drawings and the embodiments. It should be noted that in the case of no conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.

[0025] In the present disclosure, unless stated to the contrary, the orientation terms used such as "up", "down", "top" and "bottom" are generally intended to refer to the orientation shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction of a component itself: and similarly for ease of understanding and description, the terms of "inside" and "outside" refer to the inside and outside relative to the contour of each component itself. These orientation terms are not intended to limit the present disclosure.Embodiment 1

[0026] This embodiment provides a cleaning mechanism 100. Referring to FIGS. 1 and 2, the cleaning mechanism 100 includes a base 1 and a cleaning assembly 2. The base 1 is configured to mount the cleaning assembly 2, and the cleaning assembly 2 includes a cleaning member 21 rotatably arranged on the base 1. By the rotation of the cleaning member 21, the cleaning member 21 may rub against a surface to be cleaned, so as to roll up impurities such as dust on the surface to be cleaned for cleaning. Moreover, the cleaning member 21 extends in a transverse direction, such that when the cleaning mechanism 100 performs a normal cleaning, the forward direction refers to the front of the base 1, and the transverse direction herein may refer to the left-right direction of the base 1, to which reference may be made for the following descriptions of orientations. Moreover, when the cleaning member 21 is subject to a driving force, e.g., when a user manually pushes the cleaning member 21 or the driving mechanism 22 drives the cleaning member 21, at least one end of the cleaning member 21 in a transverse direction thereof may at least partially extend beyond the base 1. When the cleaning mechanism 100 performs the normal cleaning, the cleaning member 21 may perform cleaning in a first position where normal sweeping is performed. When the cleaning mechanism 100 cleans an edge area, such as a wall corner area, one end of the cleaning member 21 may be driven to extend beyond the base 1, such that the cleaning member 21 can better fit against an edge of a wall corner for cleaning. Therefore, the cleaning mechanism 100 has no cleaning blind area, has a better cleaning effect on the edge area such as the wall corner, and provides a better user experience.

[0027] The cleaning member 21 has the first position where the normal cleaning is performed, and the cleaning member 21 also has a second position where one end thereof extends beyond the base 1. When the cleaning member 21 is subject to a driving force, the cleaning member 21 can reciprocate between the first position and the second position, such that different operation modes can be switched for more flexible operation.

[0028] It can be understood that the movement of the cleaning member 21 may be a linear reciprocating motion or, of course, may be a curvilinear reciprocating motion. For example, the cleaning member 21 may swing about a swing axis. Alternatively, the cleaning member 21 may perform a "concentric square"-shaped reciprocating motion. For example, the cleaning member 21 is driven by a rocker structure of a crank 2325 and thus has many modes of movement. However, apparently, the rectilinear reciprocating motion can make the form of a driving structure of the cleaning member 21 simpler, and the moving space of the cleaning member 21 smaller, so that the size of the cleaning mechanism 100 can be smaller.

[0029] Preferably, the cleaning mechanism 100 further includes a driving mechanism 22. The driving mechanism 22 is connected to the cleaning member 21 for driving the cleaning member 21 to reciprocate linearly between the first position and the second position, achieving more labor-saving and convenient movement.

[0030] The driving mechanism 22 may be configured in various forms. In an implementation, as shown in FIGS. 2 and 3, the driving mechanism 22 includes a first driving member 221 and a connector 222. The connector 222 is in threaded fit with the cleaning member 21, and the connector 222 is driven to rotate by the first driving member 221, such that the cleaning member 21 is driven to reciprocate linearly in the transverse direction, to reciprocate between the first position and the second position.

[0031] Further, the cleaning member 21 is hollow, and the first driving member 221 and the connector 222 are both arranged inside the cleaning member 21, thereby saving more space, so that the size of the entire cleaning mechanism 100 can be smaller. The first driving member 221 can drive the connector 222 to rotate in a first direction, and can also drive the connector 222 to rotate in a second direction. The first direction is opposite to the second direction. For example, the second direction may be a counterclockwise direction when the first direction is a clockwise direction, or the second direction may be a clockwise direction when the first direction is a counterclockwise direction. When the first driving member 221 drives the connector 222 to rotate in the first direction, the cleaning member 21 is engaged with the connector 222, and the cleaning member 21 rotates and performs cleaning in the first position; and when the first driving member 221 drives the connector 222 to rotate in the second direction, the cleaning member 21 may be disengaged from the connector 222, and under the action of the connector 222, the cleaning member 21 may be driven to move in the transverse direction of the base 1 to the second position, such that the cleaning member 21 can perform a cleaning operation in the second position. The first driving member 221 may be provided as a drive motor to drive the connector 222 to rotate. The cleaning member 21 is driven to rotate by means of the first driving member 221 and the connector 222, and has a direction of rotation adjusted by means of the first driving member 221, such that the cleaning member 21 can reciprocate between the first position and the second position, achieving a simple structure. In addition, the first driving member 221 and the connector 222 are both arranged inside the cleaning member 21, not occupying the outer space of the cleaning member 21 and thus occupying a small space, so that the cleaning mechanism 100 can have both a smaller size and low manufacturing costs.

[0032] Of course, the base 1 may be further provided with an adjustment button and a controller (not shown). The controller is electrically connected to the adjustment button and the first driving member 221. When the user performs cleaning using the cleaning mechanism 100, the cleaning member 21 may perform cleaning in the first position if the cleaning mechanism 100 is in an initial state. When the user cleans a corner area such as a wall corner, the user may send an adjustment signal by pressing the adjustment button, and control, by means of the controller, the first driving member 221 to adjust the direction of rotation, thereby adjusting the steering of the cleaning member 21, such that the cleaning member 21 can extend beyond the base 1 to better fit against the corner area for use, making the operation easier and achieving a better cleaning effect.

[0033] Moreover, the base 1 is further provided with a limiting structure 31, and the cleaning member 21 is provided with a mating structure 32 which mates with the limiting structure 31 for limiting, in order to prevent the cleaning member 21 from extending too much and the cleaning member 21 from being prone to fall off or operating unstably. The limiting structure 31 mates with the mating structure 32 to limit a reciprocating stroke of the cleaning member 21, such that the extension length of the cleaning member 21 is more appropriate for both thorough cleaning and better cleaning of the corner area, achieving a more desirable cleaning effect.

[0034] Preferably, one of the limiting structure 31 and the mating structure 32 is provided as a limiting baffle 311, and the other is provided as a mating groove 321. The limiting baffle 311 slides in the mating groove 321 to limit the reciprocating stroke of the cleaning member 21. Specifically, as shown in FIGS. 1 and 10, the cleaning member 21 may be provided as a cleaning roller brush. The cleaning roller brush has a first end connected to the base 1 and a second end arranged in a suspended state, and the connector 222 may extend into the interior of the cleaning roller brush from the first end of the cleaning roller brush, so as to be connected to the cleaning roller brush to drive the cleaning roller brush to rotate. The base 1 is provided with an arc-shaped cover body covering a peripheral side of the cleaning roller brush, the limiting baffle 311 is arranged on the cleaning roller brush, and the mating groove 321 runs over the arc-shaped cover body of the base 1. The limiting baffle 311 extends into the mating groove 321 when the cleaning member 21 is mounted on the base 1. The mating groove 321 has a first groove wall and a second groove wall arranged opposite to each other in an axial direction of the cleaning roller brush. The limiting baffle 311 abuts against the first groove wall when the cleaning member 21 is in the first position for normal operation; and the limiting baffle 311 abuts against the second groove wall when the cleaning member 21 is in the second position. The movement stroke of the cleaning member 21 is consistent with the length of the mating groove 321 in the axial direction of the cleaning roller brush, such that the cleaning member 21 is in a better cleaning position, improving the cleaning efficiency.

[0035] Moreover, when the cleaning member 21 reciprocates between the first position and the second position, the cleaning member 21 may stay in any position between the first position and the second position to perform the cleaning operation, such that the cleaning member 21 has more flexible operation modes to adapt to different operation environments. Preferably, a plurality of limiting protrusions (not shown) may be provided in the mating groove 321. The plurality of limiting protrusions are arranged at intervals in an axial direction of the cleaning member 21, and the limiting baffle 311 may abut against any one of the limiting protrusions, such that the cleaning member 21 can be limited to any position between the first position and the second position. An end of each limiting protrusion may be configured in the form of an arc, and the limiting baffle 311 may pass over one limiting protrusion and be retained at another one of the limiting protrusions, such that the cleaning member 21 has more operation positions and more diversified cleaning modes.

[0036] In another implementation, the driving mechanism 22 may include a second driving member 23, a transmission assembly 232 and a mating member 231. The mating member 231 is arranged at one end of the cleaning member 21. The transmission assembly 232 is connected to the mating member 231 and the second driving member 23. The transmission assembly 232 is driven to move by the second driving member 23, so as to drive the mating member 231 to reciprocate in the transverse direction of the base 1, such that the cleaning member 21 can reciprocate in the transverse direction of the base 1 to switch the cleaning member 21 between the first position and the second position, so as to switch different operation modes.

[0037] It can be understood that the transmission assembly 232 may be configured in various forms. In an example, the transmission assembly 232 includes a nut 2321 and a lead screw 2322. The nut 2321 is arranged on the mating member 231. The lead screw 2322 is threadedly connected to the nut 2321 and extends in the transverse direction of the base 1. The second driving member 23 is connected to the lead screw 2322 for driving the lead screw 2322 to rotate. When the lead screw 2322 rotates, the nut 2321 can be driven to move along the lead screw 2322, so as to drive the mating member 231 to move in the transverse direction of the base 1. By means of the mating member 231, the cleaning member 21 is driven to move in the transverse direction of the base 1.

[0038] Specifically, as shown in FIGS. 4 to 6, the second driving member 23 may be provided as a drive motor, and the second driving member 23 is arranged on the base 1. The mating member 231 is configured in the form of a flat plate and arranged at an end of the cleaning member 21 that is connected to the base 1. The nut 2321 is mounted on one side of the mating member 231. The lead screw 2322 is threadedly connected to a screw thread, and has one end connected to the second driving member 23, such that the mating member 231 is driven to move through the sliding of the nut 2321 along the lead screw 2322, and at the same time, the cleaning member 21 can move in the transverse direction of the base 1. Moreover, the lead screw 2322 may be driven to change the direction of rotation when the second driving member 23 changes the direction of rotation, such that the direction of movement of the nut 2321 can be adjusted, and the cleaning member 21 can reciprocate in the transverse direction of the base 1.

[0039] In another example, as shown in FIGS. 7 to 9, the transmission assembly 232 may include a slider 2324 and a crank 2325. The slider 2324 is connected to the mating member 231, and the slider 2324 is provided with a sliding groove extending in a longitudinal direction of the base 1. The longitudinal direction herein may refer to the front-rear direction of the base 1. The crank 2325 is rotatably arranged on the base 1, and has one end nested in the sliding groove of the slider 2324 and the other end connected to the second driving member 23. The crank 2325 is driven to rotate by the second driving member 23, such that one end of the crank 2325 can slide along the sliding groove. The crank 2325 is pressed against the groove wall of the sliding groove, such that the mating member 231 can be driven to reciprocate in the transverse direction of the base 1.

[0040] Specifically, as shown in FIG. 9, the mating member 231 is configured in the form of a flat plate, and the slider 2324 is arranged on one side of the mating member 231 in a protruding manner. The sliding groove is in the form of a square elongated hole. At least a part of the crank 2325 is nested in the sliding groove and can slide along the sliding groove. The second driving member 23 is arranged on the base 1 and has an output end connected to the other end of the crank 2325 to drive the crank 2325 to rotate along a horizontal plane, such that the mating member 231 has a reciprocating stroke in the transverse direction of the base 1, thereby driving the cleaning member 21 to reciprocate in the transverse direction of the base 1.

[0041] It can be understood that there are many ways to drive the cleaning member 21 to reciprocate, which can be adaptively adjusted according to the actual structure of the cleaning mechanism 100 and will not be listed herein.Embodiment 2

[0042] This embodiment provides a cleaning device. The cleaning device includes the cleaning mechanism 100 described above. The cleaning device, when performing cleaning, may adjust the operation position of the cleaning member 21 according to different areas to be cleaned. For example, when the cleaning device performs a normal cleaning, the cleaning member 21 of the cleaning mechanism 100 may perform cleaning in the first position; and when the cleaning device cleans a corner area such as a wall corner and a table corner, the driving mechanism 22 of the cleaning mechanism 100 may be activated to adjust the cleaning member 21 of the cleaning mechanism 100 to the second position for cleaning, such that the cleaning member 21 can better fit against the corner area of the wall corner for cleaning. Therefore, the cleaning device does not have a cleaning blind area and thus has a better cleaning effect. In addition, the cleaning device has more diversified cleaning modes and is more convenient to perform cleaning.

[0043] Apparently, the embodiments described above are merely some rather than all of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, those of ordinary skills in the art can make other changes or variations in different forms without creative efforts, which shall all fall within the scope of protection of the present disclosure.
