[0003] To increase the flexibility of cleaning equipment, some related art cleaning devices feature a cleaning portion (e.g., a roller mop) that can be lifted and moved (expanded).

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] Please refer to Figures 1 to 7To achieve the above-mentioned objectives, an embodiment of the present invention provides a cleaning assembly, which includes: a main body 1, a cleaning part 2, and a driving part 3; wherein the cleaning part 2 is used to clean external objects and is movably disposed on the main body 1; the driving part 3 includes a moving part 31 and a guide part 32, the moving part 31 is movably disposed along a first direction, at least a portion of the guide part 32 is inclined relative to the first direction, and the moving part 31 cooperates with the guide part 32; the moving part 31 has a first position, a second position, and a third position, along the first direction, the first position is located between the second position and the third position, when the moving part 31 moves from the first position to the second position, the moving part 31 drives at least a portion of the cleaning part 2 to extend outside the main body 1 along the first direction; when the moving part 31 moves from the first position to the third position, the main body 1 abuts against the cleaning part 2 and / or the guide part 32 to prevent the cleaning part 2 from moving relative to the main body 1 along the first direction, and under the guidance of the guide part 32, the moving part 31 drives the cleaning part 2 to rise.

[0033] The cleaning component adopts this structural design, by providing a guide part 32 inclined to the first direction, and cooperating with the abutment and blocking effect of the main body part 1 on the cleaning part 2 and / or the guide part 32, can convert the driving force of the moving part 31 along the first direction into a force that drives the cleaning part 2 to lift. In this way, the moving part 31 can drive the cleaning part 2 to move along the first direction or drive the cleaning part 2 to lift. Only one driving part 3 is needed to realize the two different driving effects of lifting and translating the cleaning part 2, which can reduce the number of driving parts, which is conducive to simplifying the structure of the cleaning component, reducing its manufacturing cost, and solving the technical problem of high manufacturing cost of cleaning equipment in related technologies.

[0034] In actual use, the moving portion 31 moves in the first direction, driving the cleaning portion 2 to extend in the first direction outside the main portion 1, thereby improving the cleaning flexibility of the cleaning assembly and facilitating the cleaning of hidden corners (such as wall corners). Furthermore, the moving portion 31 moves in the first direction, combined with the guidance of the guide portion 32 and the contact of the main portion 1 with the cleaning portion 2, to convert the driving force in the first direction into a force that drives the cleaning portion 2 to rise, thereby raising the height of the cleaning portion 2, thereby avoiding obstacles and protecting objects below, thereby ensuring the operational flexibility of the cleaning device.

[0035] As can be seen from the above description, the direction in which the moving portion 31 drives the cleaning portion 2 to rise is different from the first direction. As the name implies, driving the cleaning portion 2 to rise means raising the height of the cleaning portion 2 so that it contacts objects such as the ground and carpet, thereby achieving the purpose of avoiding obstacles or preventing objects from being wet. Specifically, when the cleaning device is placed in an operating state, the direction in which the cleaning portion 2 is raised can be vertically upward or obliquely upward.

[0036] like Figure 1 and Figure 2 As shown, it should be pointed out that the above-mentioned first direction should be understood as two opposite directions, that is, the moving part 31 can move in two directions along the first direction.

[0037] As mentioned above, the cleaning part 2 is used to clean external objects. According to different cleaning requirements, the specific form of the cleaning part 2 can also be flexibly selected. For example, the cleaning part 2 can include but is not limited to a flat mop, a roller brush, a roller mop, a dust collection structure, etc., which can be freely selected according to actual needs.

[0038] Specifically, the moving part 31 is arranged on the main part 1, and the guide part 32 is arranged on the cleaning part 2; or, when the main part 1 only abuts against the cleaning part 2 when the moving part 31 moves from the first position to the third position, the moving part 31 is arranged on the cleaning part 2, and the guide part 32 is arranged on the main part 1.

[0039] That is, in actual implementation, the moving portion 31 and the guide portion 32 need to be located on both the main portion 1 and the cleaning portion 2, respectively. This allows for interaction between the moving portion 31 and the guide portion 32 to drive the cleaning portion 2. In actual implementation, the moving portion 31 can be located on the main portion 1, and the guide portion 32 can be located on the cleaning portion 2, or the guide portion 32 can be located on the main portion 1, and the moving portion 31 can be located on the cleaning portion 2.

[0040] For example, in one specific embodiment, the movable portion 31 is disposed on the main portion 1, and the guide portion 32 is disposed on the cleaning portion 2. When the movable portion 31 moves from the first position to the third position, the main portion 1 abuts against at least one of the cleaning portion 2 and the guide portion 32, thereby preventing the cleaning portion 2 from moving in the first direction. At this time, as the movable portion 31 moves, compression is generated between the movable portion 31 and the guide portion 32, causing the movable portion 31 to drive the cleaning portion 2 upward under the guidance of the guide portion 32.

[0041] For another example, in another embodiment, the guide portion 32 is provided on the main body 1, while the movable portion 31 is provided on the cleaning portion 2. When the movable portion 31 moves from the first position to the third position, the main body 1 only abuts the cleaning portion 2, not the guide portion 32, thereby preventing the cleaning portion 2 from moving in the first direction. At this time, as the movable portion 31 moves, compression is generated between the movable portion 31 and the guide portion 32, and under the guidance of the guide portion 32, the movable portion 31 drives the cleaning portion 2 to rise.

[0042] In this embodiment, the guide portion 32 includes a guide surface 321, which includes a plane or an arcuate surface. When the movable portion 31 moves from the first position to the third position, the movable portion 31 contacts the guide surface 321; and / or the tilt direction of the guide portion 32 is parallel to a preset plane, which is a plane defined by the first direction and the lifting direction of the cleaning portion 2. By designing the guide portion 32 to include a guide surface in the form of a plane or an arcuate surface, the direction of the force can be reversed and the movable portion 31 can be ensured to move more smoothly. The plane mentioned here is a plane that is tilted relative to the horizontal direction, not a horizontal plane. As a preferred embodiment, by designing the tilt direction of at least part of the guide portion 32 so that its tilt direction is parallel to the above-mentioned preset plane, when the movable portion 31 moves along the first direction, the guide portion in this tilted state can better change the direction of the extrusion force, thereby causing the movable portion 31 to drive the cleaning portion 2 to lift. Of course, in other optional embodiments, the inclination direction of at least part of the guide portion 32 may not be parallel to the preset plane, for example, there is a smaller angle between the two. In this case, the direction of the force can be changed by the inclination structure, thereby achieving the above-mentioned effect of "using one driving part 3 to achieve two different driving effects of lifting and translating the cleaning part 2".

[0043] In a preferred embodiment, the guide portion 32 includes an escape space 322 . When the movable portion 31 is in the first position and the cleaning portion 2 is lifted by an external force, the escape space 322 allows the movable portion 31 to escape.

[0044] By providing an escape space 322 on the guide portion 32, when the movable portion 31 is in the first position, the escape space 322 can be used to avoid the upward movement of the movable portion 31, thereby allowing the cleaning portion 2 to be lifted by an external force. In other words, by adopting this design, in addition to the above-mentioned active lifting of the cleaning portion 2 when the movable portion 31 moves from the first position to the third position, the passive lifting of the cleaning portion 2 under the action of an external force can also be achieved when the movable portion 31 is in the first position, which can achieve a better obstacle avoidance effect and improve the passing performance of the cleaning equipment in different environments. In other optional embodiments, the guide portion 32 may include an obliquely arranged strip hole, and the movable portion 31 is inserted into the strip hole and can move along the length direction of the strip hole. In this implementation, the direction of the force can also be changed by the squeezing effect between the movable portion 31 and the inner wall of the strip hole, and the lifting and translation of the cleaning portion 2 can be achieved by a driving portion 3. However, when the strip hole is narrow to a certain extent, it cannot provide an escape space for the movable portion 31, and the passive lifting of the cleaning portion 2 under the action of an external force cannot be achieved.

[0045] Specifically, the plane defined by the first direction and the lifting direction of the cleaning part 2 is a preset plane; wherein the projection shape of the avoidance space 322 in the preset plane is a triangle; or, along the direction from the first position to the third position, the width of the projection of the avoidance space 322 in the preset plane gradually decreases, and the width direction of the projection is the same as the lifting direction. With the above-mentioned setting method, on the one hand, a smooth force-bearing surface can be provided by a triangular structure or a structure with a gradually changing width. When the movable part 31 moves from the first position to the third position, the smooth force-bearing surface can ensure the smooth movement of the movable part 31 and the change in the direction of the force, thereby ensuring that the cleaning part 2 is lifted smoothly. On the other hand, when the movable part 31 is in the first position, if the cleaning part 2 is subjected to an external lifting force, it can be passively lifted. During the lifting process, the spare part in the triangular structure or the structure with a gradually changing width can provide a larger space for movement, so that the cleaning part 2 can move freely up and down within a larger range relative to the main part 1, thereby improving the obstacle-crossing ability of the cleaning equipment.

[0046] In actual implementation, in order to ensure that the cleaning part 2 is lifted and translated more stably and to improve the reliability of its movement, the cleaning component may include at least one of the following: a first stop structure 10, the first stop structure 10 is arranged on the main body part 1 and / or the cleaning part 2, and when the moving part 31 moves from the first position to the third position, the first stop structure 10 prevents the cleaning part 2 from moving along the first direction relative to the main body part 1; a second stop structure 20, the first stop structure 10 is arranged on the main body part 1 and / or the cleaning part 2, and when the moving part 31 moves to the second position, the second stop structure 20 prevents the cleaning part 2 from continuing to move along the first direction relative to the main body part 1; a third stop structure 30 and a fourth stop structure 40, the third stop structure 30 is arranged on the main body part 1 and / or the cleaning part 2, and the fourth stop structure 40 is arranged on the main body part 1 and / or the cleaning part 2, the third stop structure 30 and the fourth stop structure 40 prevent the cleaning part 2 from moving along the second direction relative to the main body part 1, and the second direction is a direction perpendicular to the first direction in the horizontal plane.

[0047] Among them, each of the above-mentioned stop structures is a limiting structure. Through the corresponding stop structures, the contact limit between the main body part 1 and the cleaning part 2 can be achieved, thereby limiting the relative movement range between the main body part 1 and the cleaning part 2. In actual implementation, the specific structural forms of the above-mentioned each stop structure can be various. For example, a protrusion is provided on one of the main body part 1 and the cleaning part 2, and the protrusion contacts the other of the two, thereby playing a limiting role. Of course, protrusions can also be provided on both the main body part 1 and the cleaning part 2, so that the contact between the two protrusions plays a limiting role. The stop structure can also be a part of the surface of the main body part 1 and the cleaning part 2, and the surfaces of the two directly contact each other, thereby playing the above-mentioned limiting role. Specifically, when the movable part 31 moves from the first position to the third position, the first stop structure 10 plays a stopping role, that is, the main body part 1 and the cleaning part 2 contact at the first stop structure 10, thereby preventing the cleaning part 2 from moving relative to the main body part 1 along the first direction. When the moving portion 31 moves to the second position, the second stop structure 20 acts as a stop, i.e., the main portion 1 and the cleaning portion 2 come into contact at the second stop structure 20, thereby preventing the cleaning portion 2 from continuing to move in the first direction relative to the main portion 1. The third stop structure 30 and the fourth stop structure 40 are structures for limiting the position of the cleaning portion 2 in the second direction, thereby preventing the cleaning portion 2 from moving in the second direction relative to the main portion 1.

[0048] In a preferred embodiment, the cleaning component may also include at least one of the following: a first position detection element 50, when the moving part 31 is in the first position, the corresponding trigger part on the driving part 3 triggers the first position detection element 50; a second position detection element 60, when the moving part 31 is in the second position, the corresponding trigger part on the driving part 3 triggers the second position detection element 60; a third position detection element 70, when the moving part 31 is in the third position, the corresponding trigger part on the driving part 3 triggers the third position detection element 70.

[0049] By setting the first position detection element 50, the second position detection element 60, and the third position detection element 70, when the movable part 31 moves to the first position, the second position, and the third position, the first position detection element 50, the second position detection element 60, and the third position detection element 70 can be triggered by the corresponding triggering part. At this time, the position of the movable part 31 can be accurately known, thereby accurately grasping the working status of the cleaning component, which is conducive to achieving precise control of the operation of the cleaning component.

[0050] In actual implementation, the first position detection element 50, the second position detection element 60, and the third position detection element 70 can have different specific forms, such as photoelectric switches, mechanical contact switches, etc., as long as the detection elements can accurately detect the position of the movable portion 31. Specifically, the triggering portion that triggers the first position detection element 50, the second position detection element 60, and the third position detection element 70 can be the same, or multiple triggering portions can be provided for each, so that different triggering portions can trigger the corresponding detection elements. In one specific embodiment, considering the limited lifting height of the cleaning portion 2, the distance that the movable portion 31 moves between the first and third positions is also relatively small. To achieve more efficient structural utilization, simplify the structure, and save space, the triggering portion includes a first triggering portion 80 and a second triggering portion 90. When the movable portion 31 is in the first position, the first triggering portion 80 on the driving portion 3 moves to the first position detection element 50, thereby triggering the first position detection element 50. When the movable portion 31 is in the third position, the first triggering portion 80 moves to the second position detection element 60, thereby triggering the second position detection element 60. In this way, the first triggering portion 80 can trigger both position detection elements. When the moving portion 31 moves to the second position, the second triggering portion 90 moves to the third position detection element 70, thereby triggering the third position detection element 70. In this embodiment, the driving portion 3 includes a rack, the first triggering portion 80 is disposed on the side of the rack, and the second triggering portion 90 is disposed at the end of the rack.

[0051] As a preferred embodiment, there are multiple (for example, two) moving parts 31, and the multiple moving parts 31 are arranged at intervals along the first direction; there are multiple guide parts 32, and the multiple guide parts 32 are arranged at intervals along the first direction, and the multiple moving parts 31 and the multiple guide parts 32 are arranged one-to-one correspondingly.

[0052] By providing a plurality of corresponding moving parts 31 and guiding parts 32, the balance of the driving of the cleaning part 2 by the moving part 31 can be improved, so that the lifting or outward expansion movement of the cleaning part 2 is more stable and reliable.

[0053] In a specific embodiment, the driving part includes: a rack 33, which is slidably arranged on the main body 1 along a first direction, and the moving part 31 is installed on the rack 33; a gear 34, which is engaged with the rack 33, and when the gear 34 rotates, the rack 33 is driven to move along the first direction; a motor 35, which is installed on the main body 1, and the motor 35 is connected to the gear 34 to drive the gear 34 to rotate.

[0054] Of course, this is just an optional embodiment. In specific implementation, other driving methods that can achieve linear driving can also be selected, such as a structure that converts the rotational power of the motor into a linear driving force through a structure that cooperates with a nut and a screw, a structure that drives the chain to rotate through a motor to achieve a linear driving effect, etc., as long as the driving part can drive the moving part 31 to move along the first direction.

[0055] Specifically, the cleaning component includes a rack cover, which is installed on the main body part 1, and a space for accommodating the rack 33 is formed between the rack cover and the main body part 1, wherein a first guide structure 11 extending along the first direction is provided on the main body part 1 and / or the rack cover, and a second guide structure 331 extending along the first direction is provided on the rack 33. The first guide structure 11 cooperates with the second guide structure 331 to guide the movement of the rack 33 along the first direction.

[0056] In addition, an embodiment of the present invention further provides a cleaning device, which includes a cleaning component, wherein the cleaning component is the cleaning component described above.

[0057] In actual implementation, the specific type of cleaning equipment can be selected in various forms according to different cleaning needs, such as a sweeping robot, a floor scrubber, a floor cleaning robot, etc. For example, in a specific embodiment, the cleaning equipment is a sweeping robot, and the cleaning part of the cleaning equipment is a roller mop. After adopting the above structural design, the roller mop can be lifted and translated (expanded) by a driving part 3, thereby effectively reducing its production cost while ensuring the flexibility of the sweeping robot, thereby achieving good economic benefits.

[0058] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0059] The cleaning assembly of an embodiment of the present invention includes: a main body 1, a cleaning part 2 and a driving part 3; wherein the cleaning part 2 is used to clean external objects, and the cleaning part 2 is movably arranged on the main body 1; the driving part 3 includes a moving part 31 and a guide part 32, the moving part 31 is movably arranged along a first direction, at least a part of the guide part 32 is inclined to the first direction, and the moving part 31 cooperates with the guide part 32; the moving part 31 has a first position, a second position and a third position, along the first direction, the first position is located between the second position and the third position, when the moving part 31 moves from the first position to the second position, the moving part 31 drives at least a part of the cleaning part 2 to extend to the outside of the main body 1 along the first direction; when the moving part 31 moves from the first position to the third position, the main body 1 abuts against the cleaning part 2 and / or the guide part 32 to prevent the cleaning part 2 from moving relative to the main body 1 along the first direction, and under the guiding action of the guide part 32, the moving part 31 drives the cleaning part 2 to lift. The cleaning component adopts this structural design, by providing a guide part 32 inclined to the first direction, and cooperating with the abutment and blocking effect of the main body part 1 on the cleaning part 2 and / or the guide part 32, can convert the driving force of the moving part 31 along the first direction into a force that drives the cleaning part 2 to lift. In this way, the moving part 31 can drive the cleaning part 2 to move along the first direction or drive the cleaning part 2 to lift. Only one driving part 3 is needed to realize the two different driving effects of lifting and translating the cleaning part 2, which can reduce the number of driving parts, which is conducive to simplifying the structure of the cleaning component, reducing its manufacturing cost, and solving the technical problem of high manufacturing cost of cleaning equipment in related technologies.
