The unwinding roller releases the cleaning cloth, and the take-up roller takes up the cleaning cloth released from the unwinding roller. A holding mechanism holds the cleaning cloth between the unwinding roller and the take-up roller. The cleaning cloth is detachably connected to the unwinding roller and the take-up roller.

[0006] In some embodiments, the holding mechanism further includes a retainer, the elastic portion of which is disposed on the side of the retainer facing the cleaning cloth.

[0007] In some embodiments, the elastic portion is provided at least at a first edge of the retainer, the first edge including an edge close to the unwinding roller.

[0008] In some embodiments, the elastic portion is further provided at a second edge of the retainer, the second edge including an edge close to the take-up roller.

[0009] In some embodiments, the elastic portion at the first edge and the elastic portion at the second edge are spaced apart.

[0010] In some embodiments, the elastic portion is further provided at the third and fourth edges of the retainer, the third and fourth edges intersecting with the first and second edges and connecting the first and second edges.

[0011] In some embodiments, the elastic portion at the third edge and the elastic portion at the fourth edge are spaced apart.

[0012] In some embodiments, along the spacing direction between the first edge and the second edge, the size of the elastic portion located at the first edge and the second edge is smaller than the size of the elastic portion located at the third edge and the fourth edge; along the spacing direction between the third edge and the fourth edge, the size of the elastic portion located at the first edge and the second edge is larger than the size of the elastic portion located at the third edge and the fourth edge.

[0013] In some embodiments, the width of the elastic portion at the first edge is less than 10 mm along the spacing direction between the first edge and the second edge.

[0014] In some embodiments, along the spacing direction between the first edge and the second edge, the width of the elastic portion at the second edge is less than 10 mm.

[0015] In some embodiments, along the spacing direction between the third edge and the fourth edge, the width of the elastic portion at the third edge is less than 10 mm.

[0016] In some embodiments, along the spacing direction between the third edge and the fourth edge, the width of the elastic portion at the fourth edge is less than 10 mm.

[0017] In some embodiments, the holding mechanism further includes a support disposed on the retainer, the support being located on the side of the first edge near the take-up roller and near the elastic portion at the first edge.

[0018] In some embodiments, the support is located between the first edge and the second edge, and close to the elastic portion at the first edge and the second edge.

[0019] In some embodiments, the holding mechanism further includes a support member, with an elastic portion surrounding the periphery of the support member.

[0020] In some embodiments, the elastic portion, in its uncompressed state, is higher than the support on the side facing the cleaning cloth.

[0021] In some embodiments, the elastic portion includes a plurality of elastic posts, the ends of which abut against the cleaning cloth.

[0022] In some embodiments, at least one of the plurality of elastic columns is capable of deforming at least along the direction of movement of the cleaning cloth as it passes the holding mechanism.

[0023] In some embodiments, the outer diameter of the elastic column is less than or equal to 2.5 mm.

[0025] Thirdly, this application provides a cleaning device, which includes the cleaning apparatus and base station shown in the above embodiments, and the cleaning apparatus can be docked at the base station.

[0026] The beneficial effects of this application are as follows: Unlike the prior art, this application provides an unwinding roller to release the cleaning cloth and a take-up roller to take in the cleaning cloth. Furthermore, this application also provides a pressing mechanism to press the cleaning cloth between the unwinding roller and the take-up roller. Under the action of the unwinding roller and the take-up roller, the cleaning cloth can be stretched and tightly adhered to the elastic part of the pressing mechanism. After being pressed by the cleaning cloth, the elastic part can generate an elastic force in the opposite direction. The elastic force of the elastic part can press the cleaning cloth onto the surface to be cleaned, thereby allowing the cleaning cloth to adapt to different surfaces to be cleaned and to adhere tightly to the surface to be cleaned, thereby improving the cleaning efficiency and cleaning effect of the cleaning component.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0036] The following is an exemplary description of the display stand in the embodiment of the cleaning equipment.

[0037] like Figure 1 As shown, cleaning equipment 1 is a mechanical device capable of performing cleaning functions. For example, cleaning equipment 1 can be a sweeper, floor scrubber, window cleaner, mop, sweeper truck, or sofa cleaning equipment. Cleaning equipment 1 may include a cleaning device 10 and a base station 20, and the cleaning device 10 can be docked in the base station 20.

[0038] Base station 20 serves as a docking station for cleaning device 10, enabling it to perform preset operations such as charging, collecting waste, replenishing water, and recycling wastewater. Base station 20 can communicate with cleaning device 10, allowing it to obtain location information and enabling base station 20 to access its usage status.

[0039] The cleaning device 10 is the main cleaning component in the cleaning equipment 1. It can detach from the base station 20 to perform cleaning tasks, or it can dock within the base station 20. The cleaning device 10 is capable of autonomous movement, requiring no direct human control or operation during cleaning. It also features path planning, automatic obstacle avoidance, human-machine interaction, and recharging functionality. The bottom of the cleaning device 10 is equipped with drive wheels and / or tracks for automatic movement. The cleaning device 10 can be used to clean surfaces, removing liquids, debris, particles, strips, flakes, or filaments. For example, the cleaning equipment 1 is a floor cleaning system, which includes a robotic vacuum cleaner and the base station 20. The robotic vacuum cleaner can dock within the base station 20, and the base station 20 can charge the robotic vacuum cleaner.

[0040] In some embodiments, such as Figure 2As shown, the cleaning device 10 may include a main body 100 and a cleaning component 200. The cleaning component 200 is mounted on the main body 100, and the main body 100 can drive the cleaning component 200 to move, thereby enabling the cleaning component 200 to clean the surface to be cleaned. The main body 100 can realize functions such as autonomous walking, path planning, automatic obstacle avoidance, human-computer interaction, and return to charging. The cleaning component 200 can clean the surface to be cleaned, wiping away liquids, debris, dust, and other garbage on the surface to be cleaned.

[0041] The surface to be cleaned can be the working surface of the cleaning component 200. The surface to be cleaned can be any surface that needs cleaning, such as a floor, wall, or glass surface. The surface to be cleaned can be a horizontal surface or a sloped surface.

[0042] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the cleaning assembly 200 includes a support mechanism 210, a retraction mechanism 220, and a holding mechanism 230. The support mechanism 210 can support the retraction mechanism 220 and the holding mechanism 230. The retraction mechanism 220 can be supported by the support mechanism 210 and is used to release and retract the cleaning cloth 2. The holding mechanism 230 can hold the cleaning cloth 2 on the surface to be cleaned.

[0043] The support mechanism 210 can be detachably connected to the device body 100. The retracting mechanism 220 and the holding mechanism 230 can be connected to the device body 100 through the support mechanism 210. Therefore, the cleaning component 200 can be installed on the device body 100 through the support mechanism 210, or it can be detached from the device body 100 through the support mechanism 210. Of course, in other embodiments, the support mechanism 210 can also be fixed to the device body 100, so that the device body 100 and the cleaning component 200 form an integrated structure.

[0044] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the unwinding mechanism 220 may include an unwinding roller 221 and a take-up roller 222 rotatably supported on the support mechanism 210. The two ends of the cleaning cloth 2 are respectively connected to the unwinding roller 221 and the take-up roller 222. The unwinding roller 221 releases the cleaning cloth 2, and the take-up roller 222 takes up the cleaning cloth 2 released from the unwinding roller 221.

[0045] Specifically, the unwind roller 221 and the take-up roller 222 are capable of rotating along their respective axes. The unwind roller 221 and the take-up roller 222 can be arranged side-by-side. The rotation axes of the unwind roller 221 and the take-up roller 222 can be arranged parallel to each other. One end of the cleaning cloth 2 is connected to the unwind roller 221, and most of the cleaning cloth 2 is wound on the unwind roller 221. The cleaning cloth 2 can be gradually released as the unwind roller 221 rotates. The other end of the cleaning cloth 2 is connected to the take-up roller 222, and the take-up roller 222 can gradually retract the cleaning cloth 2 as it rotates, so that the cleaning cloth 2 is wound on the take-up roller 222.

[0046] When the unwind roller 221 and the take-up roller 222 rotate simultaneously, the cleaning cloth 2 can be gradually transferred from the unwind roller 221 to the take-up roller 222. When the cleaning assembly 200 is cleaning the surface to be cleaned, the unwind roller 221 can release a clean cleaning cloth 2 to clean the ground, and the cleaning cloth 2 after wiping the surface to be cleaned can be taken up by the take-up roller 222. Thus, during the cleaning process of the cleaning assembly 200, the surface to be cleaned is always cleaned with a clean cleaning cloth 2 that has not been used to wipe the surface.

[0047] Furthermore, when the unwind roller 221 and the take-up roller 222 rotate simultaneously, their rotational speeds can be controlled to ensure that the cleaning cloth 2 is tensioned. During the cleaning process of the cleaning assembly 200, the cleaning cloth 2 slides relative to the surface under the action of the unwind roller 221 and the take-up roller 222, thereby rubbing against the surface and allowing the cleaning cloth 2 to better wipe the surface, thus improving the cleaning efficiency and effect of the cleaning assembly 200.

[0048] Since the surface to be cleaned may be a floor, wall, or other object surface, the surface of the surface to be cleaned will be uneven. During the cleaning process of the cleaning component 200, the cleaning cloth 2 between the unwinding roller 221 and the take-up roller 222 will be tightened by the unwinding roller 221 and the take-up roller 222 to become flat. This makes it difficult for the cleaning cloth 2 to clean the uneven surface to be cleaned, resulting in poor cleaning effect of the cleaning component 200.

[0049] The holding mechanism 230 in the cleaning assembly 200 can hold the cleaning cloth 2 against the surface to be cleaned, so that the cleaning cloth 2 can maintain stable contact with the surface to be cleaned, thereby cleaning the surface more effectively. Specifically, the holding mechanism 230 is disposed on the support mechanism 210 and holds the cleaning cloth 2 between the unwinding roller 221 and the take-up roller 222. The holding can be a supporting force with interaction between the holding mechanism 230 and the cleaning cloth 2. The holding mechanism 230 can provide a force to the cleaning cloth 2 toward the surface to be cleaned, so that the cleaning cloth 2 always adheres tightly to the surface to be cleaned.

[0050] It should be noted that the cleaning cloth 2 can be detachably connected to the unwind roller 221 and the take-up roller 222. For example, the end of the cleaning cloth 2 connected to the unwind roller 221 can be detachably connected to the unwind roller 221. The end of the cleaning cloth 2 connected to the take-up roller 222 can be detachably connected to the take-up roller 222. This arrangement allows the cleaning cloth 2, as a consumable, to be detached from the unwind roller 221 and the take-up roller 222 for cleaning or replacement. In some embodiments, the cleaning assembly 200 may also include the cleaning cloth 2.

[0051] like Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the holding mechanism 230 includes an elastic part 231, which faces the cleaning cloth 2 and holds the cleaning cloth 2.

[0052] The cleaning cloth 2 between the unwinding roller 221 and the take-up roller 222 can clean the surface to be cleaned. The elastic part 231 faces and presses the cleaning cloth 2 between the unwinding roller 221 and the take-up roller 222. When the cleaning assembly 200 cleans the surface to be cleaned, the elastic part 231 is located on the side of the cleaning cloth 2 opposite to the surface to be cleaned. Under the action of the unwinding roller 221 and the take-up roller 222, the cleaning cloth 2 can be stretched and pressed tightly against the elastic part 231. After being pressed by the cleaning cloth 2, the elastic part 231 can generate an elastic force in the opposite direction. The elastic force of the elastic part 231 can press the cleaning cloth 2 onto the surface to be cleaned.

[0053] Therefore, the setting of the holding mechanism 230 can ensure that the cleaning cloth 2 can always adhere tightly to the surface to be cleaned, thereby improving the cleaning efficiency and cleaning effect of the cleaning component 200.

[0054] In some embodiments, such as Figure 4 , Figure 5 as well as Figure 6 As shown, the holding mechanism 230 may also include a retainer 232, and an elastic part 231 may be provided on the side of the retainer 232 facing the cleaning cloth 2.

[0055] Specifically, the retainer 232 can serve as the base of the holding mechanism 230. The retainer 232 can be positioned between the unwinding roller 221 and the take-up roller 222 to hold the cleaning cloth 2. The elastic portion 231 is disposed on the retainer 232 and faces the cleaning cloth 2 to hold the cleaning cloth 2. This arrangement allows the retainer 232 to support the elastic portion 231, making it less prone to displacement when subjected to pressure from the cleaning cloth 2 or the surface to be cleaned, thereby improving the structural stability of the cleaning assembly 200 and enabling the elastic portion 231 to better hold the cleaning cloth 2.

[0056] The shape of the retainer 232 can be arbitrary. To ensure that the holding mechanism 230 provides good and stable support for the cleaning cloth 2, the retainer 232 can be square. The width of the retainer 232 can be approximately the same as the width of the cleaning cloth 2. The width direction of the cleaning cloth 2 is perpendicular to its direction of movement. The direction of movement of the cleaning cloth 2 can be the direction in which the cleaning cloth 2 moves relative to the holding mechanism 230 within the contact area between the holding mechanism 230 and the cleaning cloth 2. For example, Figure 6 The arrow direction B shown can indicate the direction of movement of the cleaning cloth 2. When the cleaning assembly 200 is mounted on the device body 100, the direction of movement B of the cleaning cloth 2 can be opposite to the forward direction of the device body 100. The width direction of the retainer 232 can be consistent with the width direction of the cleaning cloth 2. The length direction of the retainer 232 can be perpendicular to the width direction of the retainer 232. In some embodiments, to increase the coverage area of ​​the cleaning cloth 2 during the movement of the device body 100, the width of the retainer 232 can be greater than the length of the retainer 232.

[0057] In some embodiments, such as Figure 4 as well as Figure 5 As shown, the elastic portion 231 may be provided at least on the first edge 2321 of the retainer 232. The first edge 2321 may include the edge near the unwinding roller 221. That is, the elastic portion 231 is provided at least on the edge of the retainer 232 near the unwinding roller 221.

[0058] As the unwind roller 221 releases the cleaning cloth 2 and the take-up roller 222 collects it, the cleaning cloth 2 moves from the edge near the unwind roller 221 to the edge near the take-up roller 222. Therefore, the cleaning cloth 2 near the edge of the unwind roller 221 is always clean. After cleaning the surface to be cleaned, the dirty cleaning cloth 2 is wound up and collected by the take-up roller 222. By setting the elastic part 231 on the edge of the retainer 232 near the take-up roller 222, the clean cleaning cloth 2 released by the unwind roller 221 can be pressed against the surface to be cleaned by the elastic part 231 when it moves to the edge of the retainer 232 near the take-up roller 222. This allows the clean cleaning cloth 2 to adhere to and wipe the surface to be cleaned, thereby improving the cleaning effect and cleaning efficiency of the cleaning assembly 200.

[0059] In some embodiments, such as Figure 4 as well as Figure 5As shown, the elastic portion 231 may also be provided on the second edge 2322 of the retainer 232, the second edge 2322 including an edge close to the take-up roller 222. Here, the edge close to the take-up roller 222 means that this edge is closer to the take-up roller 222 than the first edge 2321. The first edge 2321 may be opposite to the second edge 2322. The first edge 2321 and the second edge 2322 may be two edges on the retainer 232 that are opposite each other in the length direction.

[0060] Specifically, the elastic portion 231 is not only provided on the first edge 2321 of the retainer 232 near the unwinding roller 221, but also on the edge of the take-up roller 222 of the retainer 232. The increase in the area of ​​the elastic portion 231 can also increase the area of ​​the cleaning cloth 2 being pressed by the elastic portion 231, thereby increasing the area of ​​the cleaning cloth 2 in contact with the surface to be cleaned, thereby increasing the cleaning area of ​​the cleaning assembly 200 and improving the cleaning effect of the cleaning assembly 200.

[0061] In some embodiments, the elastic portion 231 at the first edge 2321 and the elastic portion 231 at the second edge 2322 are spaced apart.

[0062] This configuration allows the elastic portions 231 at the first edge 2321 and the second edge 2322 to support the cleaning cloth 2 at opposite edges of the retainer 232, ensuring the cleaning surface of the cleaning cloth 2 facing away from the retainer 232 remains flat and that the force on the cleaning cloth 2 is more even. During the cleaning process of the cleaning assembly 200, the elastic portions 231 on the side of the retainer 232 facing the cleaning cloth 2 can push the cleaning cloth 2 towards the surface to be cleaned, resulting in a larger cleaning area and better cleaning effect from the cleaning assembly 200.

[0063] In some embodiments, an elastic portion 231 may also be provided at the midpoint between the elastic portion 231 at the first edge 2321 and the elastic portion 231 at the second edge 2322, so that the side of the retainer 232 facing the cleaning cloth 2 is fully covered with the elastic portion 231. Increasing the area of ​​the elastic portion 231 on the retainer 232 in this way expands the area of ​​the cleaning cloth 2 in contact with the surface to be cleaned, thereby increasing the cleaning area of ​​the cleaning assembly 200 and improving its cleaning effect.

[0064] Alternatively, in some embodiments, the elastic portion 231 at the first edge 2321 and the elastic portion 231 at the second edge 2322 may not be provided. This arrangement not only allows the elastic portions 231 at the first edge 2321 and the elastic portion 231 at the second edge 2322 to support the cleaning cloth 2, ensuring the cleaning cloth 2 adheres to the surface to be cleaned, but also reduces friction between the cleaning cloth 2 and the surface to be cleaned when the cleaning cloth 2 slides relative to the surface under the action of the unwinding roller 221 and the take-up roller 222. This facilitates the sliding of the cleaning cloth 2 and the replacement of the fabric tightly adhering to the surface to be cleaned, and reduces the rotational driving force of the unwinding roller 221 and the take-up roller 222.

[0065] In some embodiments, such as Figure 4 As shown, the elastic portion 231 may also be provided on the third edge 2323 and the fourth edge 2324 of the retainer 232. The third edge 2323 and the fourth edge 2324 intersect with and connect the first edge 2321 and the second edge 2322. The third edge 2323 may be opposite to the fourth edge 2324. The third edge 2323 and the fourth edge 2324 may be two opposite edges of the retainer 232 in the width direction.

[0066] Specifically, the two ends of the third edge 2323 are connected to the first edge 2321 and the second edge 2322 respectively, forming an intersection. The two ends of the fourth edge 2324 are also connected to the first edge 2321 and the second edge 2322 respectively, forming an intersection. The first edge 2321, the second edge 2322, the third edge 2323, and the fourth edge 2324 can be combined to form a ring.

[0067] By providing elastic portions 231 at the third edge 2323 and the fourth edge 2324 of the retainer 232, the cleaning cloth 2 can be further supported at the positions of the third edge 2323 and the fourth edge 2324. The expansion of the area of ​​the elastic portion 231 can also increase the area of ​​the cleaning cloth 2 being pressed by the elastic portion 231, thereby increasing the area of ​​the cleaning cloth 2 in contact with the surface to be cleaned, increasing the cleaning area of ​​the cleaning assembly 200 and improving the cleaning effect of the cleaning assembly 200.

[0068] In some embodiments, the elastic portion 231 at the third edge 2323 and the elastic portion 231 at the fourth edge 2324 are spaced apart. This arrangement allows the elastic portion 231 at the third edge 2323 and the elastic portion 231 at the fourth edge 2324 to support the cleaning cloth 2 at the two opposite edges of the retainer 232, so that the cleaning cloth 2 can remain flat in the spaced direction of the third edge 2323 and the fourth edge 2324.

[0069] Furthermore, under the action of the elastic portion 231 corresponding to the first edge 2321, the second edge 2322, the third edge 2323 and the fourth edge 2324, the force on the cleaning cloth 2 can be more balanced, making the side of the cleaning cloth 2 facing away from the retainer 232 flatter. Moreover, the cleaning cloth 2 is less likely to wrinkle when sliding relative to the surface to be cleaned, which can reduce the situation where the cleaning cloth 2 is torn due to uneven force.

[0070] In some embodiments, such as Figure 4 , Figure 5 as well as Figure 6 As shown, the holding mechanism 230 may further include a support member 233 disposed on the retainer 232. The support member 233 is located on the side of the first edge 2321 near the take-up roller 222 and near the elastic portion 231 at the first edge 2321. Here, "the support member 233 near the elastic portion 231 at the first edge 2321" means that the support member 233 and the elastic portion 231 at the first edge 2321 are disposed adjacent to each other.

[0071] Specifically, as the cleaning cloth 2 moves from the unwinding roller 221 to the take-up roller 222, the elastic portion 231 is tilted by the cleaning cloth 2. By placing the support member 233 on the side of the first edge 2321 closer to the take-up roller 222, the support member 233 can support the elastic portion 231 at the first edge 2321 when the elastic portion 231 is tilted, thereby improving the structural stability of the cleaning assembly 200.

[0072] In some embodiments, the support member 233 may be a material with supporting force, such as memory foam or UPE foam. In some embodiments, the support member 233 may also be other materials with supporting force. The supporting force of the support member 233 refers to the ability of the support member 233 to resist elastic deformation better than that of the elastic part 231. This allows the support member 233 to better support the elastic part 231.

[0073] In some embodiments, the side of the support 233 facing the cleaning cloth 2 is a smooth surface with a surface roughness below a threshold, thereby reducing the friction force when the cleaning cloth 2 moves.

[0074] In some embodiments, such as Figures 4 to 7 As shown, the support member 233 can be located between the first edge 2321 and the second edge 2322, and close to the elastic portion 231 at the first edge 2321 and the second edge 2322. In other words, one side of the support member 233 is adjacent to the elastic portion 231 located at the first edge 2321, and the other side of the support member 233 is adjacent to the elastic portion 231 located at the second edge 2322.

[0075] Since the cleaning device 10 may move in multiple directions during the cleaning process, the cleaning cloth 2 causes the elastic part 231 located at the second edge 2322 to tilt towards the first edge 2321. Therefore, by placing the support member 233 between the first edge 2321 and the second edge 2322, the support member 233 can jointly support the elastic part 231 located at the first edge 2321 and the elastic part 231 located at the second edge 2322, so that the elastic part 231 located at the first edge 2321 and the elastic part 231 located at the second edge 2322 can maintain the state of pressing the cleaning cloth 2, thereby improving the structural stability of the cleaning assembly 200.

[0076] In some embodiments, such as Figure 5 as well as Figure 6 As shown, in the uncompressed state, the elastic part 231 is higher than the support member 233 on the side facing the cleaning cloth 2. That is, when the elastic part 231 is pressed against the cleaning cloth 2, the side of the elastic part 231 facing the cleaning cloth 2 is higher than the support member 233.

[0077] As an example, the height of the support member 233 can be as follows: Figure 5 As shown in L1, the height of the elastic part 231 can be as follows: Figure 5 As shown in L2, L1 < L2.

[0078] If the side of the elastic part 231 facing the cleaning cloth 2 is lower than or flush with the support member 233 when it is not compressed, the elastic part 231 will be lower than the support member 233 when it is compressed by the cleaning cloth 2. As a result, the support member 233 will lift the cleaning cloth 2, and the elastic part 231 will not be able to apply elastic force to the cleaning cloth 2, thus failing to push the cleaning cloth 2 toward the surface to be cleaned.

[0079] Therefore, by setting the side of the elastic part 231 facing the cleaning cloth 2 higher than the support member 233 when it is not compressed, it can be ensured that the elastic part 231 can press against the cleaning cloth 2 when the cleaning cloth 2 is tensioned by the unwinding roller 221 and the take-up roller 222, so that the cleaning cloth 2 is in close contact with the surface to be cleaned.

[0080] like Figure 6As shown, when the elastic part 231 is compressed by the cleaning cloth 2, the side of the elastic part 231 facing the cleaning cloth 2 can be higher than the support member 233, so that the cleaning cloth 2 and the support member 233 are spaced apart. This arrangement not only allows the elastic part 231 to hold and tension the cleaning cloth 2, but also reduces the frictional force when the cleaning cloth 2 slides against the surface to be cleaned. Alternatively, in some embodiments, when the elastic part 231 is compressed by the cleaning cloth 2, the side of the elastic part 231 facing the cleaning cloth 2 can be flush with the support member 233, so that the side of the cleaning cloth 2 facing away from the support member 233 and the elastic part 231 is more flush.

[0081] In some embodiments, such as Figure 5 as well as Figure 6 As shown, the elastic part 231 may include a plurality of elastic posts 2311, the ends of which abut against the cleaning cloth 2. The side of each elastic post 2311 away from the cleaning cloth 2 is disposed on the retainer 232.

[0082] The multiple elastic pillars 2311 can be multiple elastic strip-shaped structures, such as wool strips. The elastic pillars 2311 can also be made of elastic materials such as sponge, memory foam, or rubber.

[0083] Specifically, when the cleaning cloth 2 is tensioned under the action of the retraction mechanism 220, it contacts and abuts the end of the elastic column 2311. The elastic column 2311 is pressed by the cleaning cloth 2 and undergoes elastic deformation. The elastic force of the elastic column 2311 will press the cleaning cloth 2 onto the surface to be cleaned.

[0084] Furthermore, the arrangement of multiple elastic pillars 2311 abutting against the cleaning cloth 2 allows the cleaning cloth 2 to provide elastic force corresponding to different uneven positions on the surface to be cleaned by different elastic pillars 2311. This enables the cleaning cloth 2 to fit more closely to the surface to be cleaned, thereby solving the problem of uneven grounding of the cleaning cloth 2 when facing an uneven surface to be cleaned, and improving the cleaning effect of the cleaning component 200.

[0085] Of course, in other embodiments, the elastic part 231 can be composed of multiple springs or other elastic elements such as sheet metal, which will not be specifically listed here.

[0086] In some embodiments, at least one of the plurality of elastic columns 2311 is capable of deforming at least along the direction of movement of the cleaning cloth 2 as it passes the holding mechanism 230.

[0087] Specifically, under the action of the unwinding roller 221 and the take-up roller 222, the cleaning cloth 2 moves from the first edge 2321 to the second edge 2322. Therefore, at least one of the multiple elastic pillars 2311 deforms in the direction from the first edge 2321 to the second edge 2322. In other words, at least one of the multiple elastic pillars 2311 tilts and collapses in the direction of movement of the cleaning cloth 2. The collapse of the elastic pillar 2311 allows it to elastically press the cleaning cloth 2 against the surface to be cleaned.

[0088] The end of the elastic column 2311 abuts against the cleaning cloth 2. Therefore, under the drag of the cleaning cloth 2, the elastic column 2311 can deform and fall along the moving direction of the cleaning cloth 2 when it passes the holding mechanism 230. Therefore, after the cleaning cloth 2 is tightened by the retraction mechanism 220, most of the elastic columns 2311 can fall in the same direction, so that the plane of the part of the cleaning cloth 2 that the elastic column 2311 abuts can be flatter, and the multiple elastic columns 2311 can also support each other to improve the structural stability of the cleaning component 200.

[0089] Since a support member 233 is provided between the elastic portion 231 at the first edge 2321 and the elastic portion 231 at the second edge 2322, when the cleaning cloth 2 is subjected to the action of the multiple elastic columns 2311 by the retracting mechanism 220, causing the multiple elastic columns 2311 to deform and fall over in the interval direction between the first edge 2321 and the second edge 2322, the support member 233 can support the fallen elastic columns 2311, thereby reducing the excessive falling of the elastic columns 2311, ensuring that one end of the elastic column 2311 abuts against the cleaning cloth 2, and improving the counter-pushing effect of the elastic column 2311 on the cleaning cloth 2, so that the cleaning cloth 2 can better fit the surface to be cleaned.

[0090] In some embodiments, the outer diameter of the elastic column 2311 is less than or equal to 2.5 mm. For example, the outer diameter of the elastic column 2311 can be 0.5 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.3 mm or 2.5 mm, etc.

[0091] Among them, the outer diameter of the elastic column 2311 refers to the largest diameter of the elastic column 2311.

[0092] The cleaning device 10 can be a small device such as a sweeper or a handheld cleaner. The surface to be cleaned may be an uneven floor, sofa surface, or other object surface. However, floors and sofa surfaces have many small pits. Therefore, setting the outer diameter of the elastic column 2311 to be less than or equal to 2.5mm allows the elastic column 2311 to better adapt to the shape of the floor at the point where it presses against the cleaning cloth 2, thereby enhancing the cleaning effect of the cleaning cloth 2 on the floor, sofa surface, and other surfaces to be cleaned. If the outer diameter of the elastic column 2311 is greater than 2.5mm, the cleaning component 200 will not be able to clean the small pits in the surface to be cleaned, reducing the cleaning effect of the cleaning device 10.

[0093] In some embodiments, such as Figure 7 As shown, the elastic part 231 can surround the periphery of the support member 233. This arrangement facilitates the support member 233 in supporting the elastic part 231. Furthermore, by placing the support member 233 in the middle of the elastic part 231, the area of ​​the cleaning cloth 2 facing the surface to be cleaned can be increased after the elastic part 231 supports the cleaning cloth 2, thereby improving the cleaning effect of the cleaning assembly 200.

[0094] In some embodiments, such as Figure 7 As shown, the elastic portion 231 on the retainer 232 can be rectangular, and the support member 233 is disposed in the middle of the rectangular elastic portion 231 to support the elastic portion 231.

[0095] In some embodiments, the number of support members 233 can be multiple, with the multiple support members 233 spaced apart, and elastic portions 231 surrounding the periphery of each support member 233. The multiple support members 233 are arranged along the spacing direction between the first edge 2321 and the second edge 2322, and the elastic portions 231 are disposed at the intervals between the first edge 2321, the second edge 2322, and the multiple support members 233. Alternatively, the multiple support members 233 can also be arranged along the spacing direction between the third edge 2323 and the fourth edge 2324.

[0096] Of course, in other embodiments, the support member 233 may be disposed only between the elastic portion 231 at the first edge 2321 and the elastic portion 231 at the second edge 2322, without being surrounded by the elastic portion 231. Alternatively, the support member 233 may have other arrangements, which will not be specifically listed here.

[0097] In some embodiments, along the spacing direction between the first edge 2321 and the second edge 2322, the size of the elastic portion 231 located at the first edge 2321 and the second edge 2322 may be smaller than the size of the elastic portion 231 located at the third edge 2323 and the fourth edge 2324.

[0098] As an example, the spacing direction between the first edge 2321 and the second edge 2322 can be as follows: Figure 7 As shown in the X direction, the dimensions of the elastic portion 231 located at the first edge 2321 are as follows: Figure 7 As shown in the middle length L3, the dimensions of the elastic portion 231 at the second edge 2322 are as follows: Figure 7 As shown in the medium length L4, the dimensions of the elastic portion 231 located at the third edge 2323 and the fourth edge 2324 are as follows: Figure 7 The intermediate length L5 is shown. Where (L3+L4)<L5.

[0099] Since the X-direction of the interval between the first edge 2321 and the second edge 2322 is the direction of movement of the cleaning cloth 2 under the action of the unwinding roller 221 and the take-up roller 222, which is the main cleaning direction of the cleaning cloth 2, the size of the elastic part 231 is set in this way so that the cleaning cloth 2 has a larger area to clean the surface to be cleaned during the cleaning process, thereby improving the cleaning efficiency and cleaning effect.

[0100] Along the spacing direction between the third edge 2323 and the fourth edge 2324, the size of the elastic portion 231 located at the first edge 2321 and the second edge 2322 can be larger than the size of the elastic portion 231 located at the third edge 2323 and the fourth edge 2324.

[0101] As an example, the spacing direction between the third edge 2323 and the fourth edge 2324 can be as follows: Figure 7 As shown in the Y direction, the dimensions of the elastic portion 231 located at the first edge 2321 and the second edge 2322 can be as follows: Figure 7 As shown in the middle length L6, the size of the elastic portion 231 at the third edge 2323 can be as follows: Figure 7 As shown in the middle length L7, the dimensions of the elastic portion 231 at the fourth edge 2324 can be as follows: Figure 7 The intermediate length L8 is shown. Where L6 > (L7 + L8).

[0102] This configuration reduces the area occupied by the cleaning cloth 2 in the Y direction of the interval between the third edge 2323 and the fourth edge 2324, thereby reducing the size of the cleaning component 200 and making the cleaning component 200 and the cleaning device 10 more compact.

[0103] In some embodiments, along the spacing direction X between the first edge 2321 and the second edge 2322, the width of the elastic portion 231 at the first edge 2321 is less than 10 mm.

[0104] As an example, the elastic portion 231 at the first edge 2321 has a width along the spacing direction X between the first edge 2321 and the second edge 2322 as shown in the figure. Figure 7The width L3 is shown in the figure.

[0105] For example, along the interval X between the first edge 2321 and the second edge 2322, the width L3 of the elastic portion 231 at the first edge 2321 can be a value such as 5mm, 6mm, 7mm, 8mm, 9mm or 9.5mm.

[0106] If the width L3 of the elastic portion 231 at the first edge 2321 is greater than or equal to 10 mm along the interval X between the first edge 2321 and the second edge 2322, then the elastic portion 231 at the first edge 2321 will occupy a large size along the interval X between the first edge 2321 and the second edge 2322, thereby increasing the size of the cleaning component 200 and the cleaning device 10. In some embodiments, the cleaning device 10 can be a small device such as a robot vacuum cleaner or a handheld cleaner. If the size of the cleaning device 10 is too large, the cleaning device 10 will not be able to enter some narrow areas for cleaning, thereby reducing the cleaning area of ​​the cleaning device 10, affecting the cleaning effect of the cleaning device 10, and reducing the user experience.

[0107] Therefore, by setting the width L3 of the elastic portion 231 at the first edge 2321 to less than 10 mm in the interval direction X between the first edge 2321 and the second edge 2322, the size of the cleaning assembly 200 in the interval direction X between the first edge 2321 and the second edge 2322 can be reduced, thereby reducing the size of the cleaning device 10, making the cleaning device 10 more compact, thereby increasing the flexibility of the cleaning device 10 and expanding the cleaning area of ​​the cleaning device 10.

[0108] In some embodiments, along the spacing direction between the first edge 2321 and the second edge 2322, the width of the elastic portion 231 at the second edge 2322 is less than 10 mm.

[0109] As an example, the elastic portion 231 at the second edge 2322 has a width along the distance X between the first edge 2321 and the second edge 2322 as shown in the figure. Figure 7 The width L4 is shown in the figure.

[0110] For example, along the interval direction X between the first edge 2321 and the second edge 2322, the width L4 of the elastic portion 231 at the second edge 2322 can be a value such as 5mm, 6mm, 7mm, 8mm, 9mm or 9.5mm.

[0111] If the width L4 of the elastic portion 231 at the second edge 2322 is greater than or equal to 10 mm along the interval X between the first edge 2321 and the second edge 2322, then the elastic portion 231 at the second edge 2322 will occupy a large size along the interval X between the first edge 2321 and the second edge 2322, thereby increasing the size of the cleaning assembly 200 and the cleaning device 10. Therefore, by setting the width L4 of the elastic portion 231 at the second edge 2322 to less than 10 mm along the interval X between the first edge 2321 and the second edge 2322, the size of the cleaning assembly 200 in the interval X between the first edge 2321 and the second edge 2322 can be reduced, thereby reducing the size of the cleaning device 10, making the cleaning device 10 more compact, and further increasing the flexibility of the cleaning device 10 and expanding the cleaning area of ​​the cleaning device 10.

[0112] In some embodiments, along the Y direction of the interval between the third edge 2323 and the fourth edge 2324, the width of the elastic portion 231 at the third edge 2323 is less than 10 mm.

[0113] As an example, the elastic portion 231 at the third edge 2323 has a width along the distance Y between the third edge 2323 and the fourth edge 2324 as shown in the figure. Figure 7 The width L7 is shown in the figure.

[0114] For example, along the Y direction of the interval between the third edge 2323 and the fourth edge 2324, the width L7 of the elastic part 231 at the third edge 2323 can be a value such as 5mm, 6mm, 7mm, 8mm, 9mm or 9.5mm.

[0115] If the width of the elastic portion 231 at the third edge 2323 is greater than or equal to 10 mm along the interval Y between the third edge 2323 and the fourth edge 2324, then the elastic portion 231 at the third edge 2323 will occupy a large size in the interval Y between the third edge 2323 and the fourth edge 2324, thereby increasing the size of the cleaning assembly 200 and the cleaning device 10. Therefore, by setting the width L7 of the elastic portion 231 at the third edge 2323 to less than 10 mm in the interval Y between the third edge 2323 and the fourth edge 2324, the size of the cleaning assembly 200 in the interval Y between the third edge 2323 and the fourth edge 2324 can be reduced, thereby reducing the size of the cleaning device 10, making the cleaning device 10 more compact, and further increasing the flexibility of the cleaning device 10 and expanding the cleaning area of ​​the cleaning device 10.

[0116] In some embodiments, along the Y direction of the interval between the third edge 2323 and the fourth edge 2324, the width of the elastic portion 231 at the fourth edge 2324 is less than 10 mm.

[0117] As an example, the elastic portion 231 at the fourth edge 2324 has a width along the distance Y between the third edge 2323 and the fourth edge 2324 as shown in the figure. Figure 7 The width L8 is shown in the figure.

[0118] For example, along the Y direction of the interval between the third edge 2323 and the fourth edge 2324, the width of the elastic part 231 at the third edge 2323 can be 5mm, 6mm, 7mm, 8mm, 9mm or 9.5mm.

[0119] If the width of the elastic portion 231 at the fourth edge 2324 is greater than or equal to 10 mm along the interval Y between the third edge 2323 and the fourth edge 2324, then the elastic portion 231 at the fourth edge 2324 will occupy a large size in the interval Y between the third edge 2323 and the fourth edge 2324, thereby increasing the size of the cleaning assembly 200 and the cleaning device 10. Therefore, by setting the width of the elastic portion 231 at the fourth edge 2324 to less than 10 mm in the interval Y between the third edge 2323 and the fourth edge 2324, the size of the cleaning assembly 200 in the interval Y between the third edge 2323 and the fourth edge 2324 can be reduced, thereby reducing the size of the cleaning device 10, making the cleaning device 10 more compact, and further increasing the flexibility of the cleaning device 10 and expanding the cleaning area of ​​the cleaning device 10.

[0120] In summary, this application provides an unwinding roller 221 to release the cleaning cloth 2 and a take-up roller 222 to take in the cleaning cloth 2. Furthermore, this application provides a holding mechanism 230 to hold the cleaning cloth 2 between the unwinding roller 221 and the take-up roller 222. Under the action of the unwinding roller 221 and the take-up roller 222, the cleaning cloth 2 can be stretched and tightly adhered to the elastic part 231 of the holding mechanism 230. After being pressed by the cleaning cloth 2, the elastic part 231 can generate an elastic force in the opposite direction. The elastic force of the elastic part 231 can press the cleaning cloth 2 onto the surface to be cleaned, thereby enabling the cleaning cloth 2 to adapt to different surfaces to be cleaned and to adhere tightly to the surface to be cleaned, thereby improving the cleaning efficiency and cleaning effect of the cleaning component 200.
