[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] like Figure 1 As shown, a Cartesian coordinate system is established. The length direction of the cleaning mechanism 1000 is defined to be parallel to the x-axis, the width direction of the cleaning mechanism 1000 can be parallel to the y-axis, and the height direction of the cleaning mechanism 1000 can be parallel to the z-axis. It is understood that the above definitions are only for the convenience of understanding the relative positional relationships of the various parts of the cleaning mechanism 1000 and should not be construed as limitations on this application.

[0046] The embodiment provides a cleaning mechanism 1000, which can be applied to surface cleaning equipment. The cleaning mechanism 1000 can be used to scrape away dirt and sewage from the surface to be cleaned. The surface cleaning equipment can be one of the following, including but not limited to sweeping robots, mopping robots, floor scrubbing robots, and desktop cleaning robots. Correspondingly, the surface to be cleaned can be a floor or a desktop.

[0047] like Figure 1 As shown, the cleaning mechanism 1000 may include a roller brush cover 100, a scraper 200, and a bracket 300.

[0048] Combined again Figure 7 The scraper 200 may include a cleaning section 210 and an engaging section 230. The engaging section 230 may be disposed on one side of the cleaning section 210.

[0049] Combined again Figure 5 The scraper 200 can be connected to one side of the roller brush cover 100 via a bracket 300. Specifically, the bracket 300 can be fixedly connected to one side of the roller brush cover 100, and the side of the bracket 300 near the roller brush cover 100 can have an insertion groove 340 extending in a first direction. In addition, at least one limiting block 350 is also provided on the side of the bracket 300 near the roller brush cover 100, and the at least one limiting block 350 can be located on one side of the opening structure of the insertion groove 340. In some embodiments, the first direction can be parallel to the length direction of the cleaning mechanism 1000.

[0050] The insertion portion 230 of the scraper 200 can be inserted into the insertion groove 340. At least one limiting block 350 can abut against the side of the insertion portion 230 away from the bottom of the insertion groove 340. In this embodiment, the limiting block 350 can confine the insertion portion 230 within the insertion groove 340, preventing the insertion portion 230 from arbitrarily disengaging from the insertion groove 340. This also achieves pre-fixation between the scraper 200 and the bracket 300.

[0051] In existing assembly techniques, the scraper 200 is typically clamped directly between the brush cover 100 and the bracket 300. During assembly, this can easily lead to movement of the scraper 200, resulting in incomplete assembly, low assembly efficiency, and reduced production capacity.

[0052] In this application, the scraper 200 and the bracket 300 can be pre-fixed before the bracket 300 and the roller brush cover 100 are fixedly installed, facilitating the positioning and installation of the two components. Compared with the prior art, this application can significantly reduce the probability of the scraper 200 shifting relative to the bracket 300 and the roller brush cover 100, making it easier to assemble the scraper 200 into place. Consequently, it can also improve assembly efficiency, increase production capacity, and reduce production costs.

[0053] like Figures 2 to 4 As shown, the roller brush cover 100 may further include a roller brush cover body 110 and an elastic buckle assembly 120. The roller brush cover body 110 has a perforated hole 112, allowing the roller brush in the surface cleaning device to contact the surface to be cleaned, thus providing a cleaning function. Additionally, a mounting portion 111 may be formed on one side of the roller brush cover body 110. The mounting portion 111 may be located on one side of the perforated hole 112 and may extend along the length of the cleaning mechanism 1000. In this embodiment, the roller brush cover body 110 may include a near-ground side 1102 and a far-ground side 1101.

[0054] The elastic buckle assembly 120 may include a latch 121, a torsion spring 123, and a pin 122. The latch 121 may pass through the mounting portion 111 of the brush cover body 110 and is rotatably connected to the mounting portion 111 via the pin 122. The torsion spring 123 may be sleeved on the pin 122 and abuts against both the mounting portion 111 and the latch 121. In this embodiment, the torsion spring 123 can be used to drive the latch 121 to reset, maintaining the latched state.

[0055] It is understood that the latch 121 may include an integral operating part 1211 and a fastening part 1212. The operating part 1211 may protrude relative to the near-ground side 1102 of the mounting part 111, and the fastening part 1212 may protrude relative to the far-ground side 1101 of the mounting part 111. In application, the fastening part 1212 can be used to fasten and connect with the main unit of the surface cleaning equipment, realizing the connection between the cleaning mechanism 1000 and the main unit. The user can drive the latch 121 to rotate through the operating part 1211 to fasten or de-fasten the fastening part 1212 with or away from the main unit.

[0056] In this embodiment, the roller brush cover 100 may include two symmetrical elastic buckle assemblies 120, which can cooperate to achieve a detachable connection between the cleaning mechanism 1000 and the main unit.

[0057] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the bracket 300 may include a bracket body 310, a first partition 320, and a second partition 330.

[0058] In some embodiments, the bracket body 310 can be fixedly connected to the assembly part 111 by screws, and the bracket body 310 can be located on the ground side 1102 of the roller brush cover body 110. In addition, the bracket body 310 can be provided with a through hole 370 opposite to the elastic buckle assembly 120, and the operating part 1211 of the latch 121 can pass through the through hole 370 and protrude from the side of the bracket body 310 away from the roller brush cover body 110 for easy access by the user.

[0059] In other embodiments, the bracket body 310 may also be detachably connected to the assembly portion 111 of the brush cover body 110 by means of snap-fit ​​or other methods. Of course, the bracket body 310 may also be connected to the assembly portion 111 by means of non-detachable connection such as bonding, riveting or welding.

[0060] In this embodiment, both the first partition 320 and the second partition 330 are disposed on the side of the support body 310 near the roller brush cover body 110 and near the perforated hole 112. Both the first partition 320 and the second partition 330 are parallel to both the length and height directions of the cleaning mechanism 1000. In this embodiment, the first partition 320 and the second partition 330 are spaced apart and cooperate to form an insertion groove 340 extending along a first direction. Furthermore, in some embodiments, the first partition 320, the second partition 330, and the support body 310 can be an integral structure, formed by integral injection molding.

[0061] The side of the insertion groove 340 near the roller brush cover body 110 may be an open structure. In the first direction, both ends of the insertion groove 340 may be closed by a structure such as a surrounding plate on the bracket body 310, which can restrict the insertion part 230 of the scraper 200 from swinging freely in the insertion groove 340 in the first direction.

[0062] Of course, in other embodiments, the two ends of the mating groove 340 may also be closed by a structure such as a surrounding plate on the assembly part 111.

[0063] like Figure 5 and Figure 6 As shown, the limiting block 350 can be disposed on the side of the second partition 330 near the brush cover body 110. The limiting block 350 can protrude relative to the side of the second partition 330 near the first partition 320, that is, the limiting block 350 can cover a portion of the opening structure of the insertion groove 340. In some embodiments, the limiting block 350 can be integrally formed with the second partition 330.

[0064] Furthermore, the distance between the surface of the limiting block 350 near the support body 310 and the support body 310 can be greater than the distance between the surface of the first partition 320 away from the support body 310 and the support body 310. That is, the height of the second partition 330 can be greater than the height of the first partition 320. Thus, a height difference can be formed between the limiting block 350 and the first partition 320, which facilitates the insertion of the scraper 200's mating portion 230 into the mating groove 340.

[0065] In other embodiments, the second partition 330 may also be at the same height as the first partition 320. A gap is left between the end of the limiting block 350 away from the second partition 330 and the first partition 320 to allow for the insertion of the mating part 230.

[0066] In some embodiments, the bracket 300 may include three limiting blocks 350, which are evenly spaced along a first direction on the side of the second partition 330 away from the bracket body 310. This also makes the forces on each part of the mating portion 230 uniform, reducing the probability of the mating portion 230 disengaging from the mating groove 340.

[0067] In other embodiments, the bracket 300 may also include one, four, or six limiting blocks 350. When the bracket 300 includes multiple limiting blocks 350, the multiple limiting blocks 350 may be evenly or non-uniformly spaced on the second partition 330 along the first direction.

[0068] Furthermore, the first partition 320 is provided with three clearance notches 321, which can be correspondingly set with three limiting blocks 350. Specifically, the projection of the clearance notch 321 on the bracket body 310 and the projection of the corresponding limiting block 350 on the bracket body 310 are at the same position in the first direction. On the one hand, when disassembling and assembling the scraper 200 and the bracket 300, it is convenient for the operator to insert the mating part 230 into the mating groove 340 or pull it out of the mating groove 340 past the corresponding limiting block 350, making it convenient for the operator to apply force to the corresponding position of the scraper 200. On the other hand, it is also convenient to clean the dirt in the mating groove 340 when cleaning the cleaning mechanism 1000, thereby improving the self-cleaning efficiency of the cleaning mechanism 1000.

[0069] like Figure 3 and Figure 7 As shown, the mating portion 230 can be generally plate-shaped and is parallel to both the length and height directions of the cleaning mechanism 1000. The mating portion 230 can be matched with the mating groove 340. When the mating portion 230 is inserted into the mating groove 340, the circumferential sidewall of the mating portion 230 can fit against the inner wall of the mating groove 340 to prevent the mating portion 230 from moving freely in the mating groove 340. In addition, three limiting blocks 350 can abut against the side of the mating portion 230 away from the bottom of the mating groove 340.

[0070] In this embodiment, the scraper 200 further includes a connecting portion 220 connecting the cleaning portion 210 and the insertion portion 230. In some embodiments, the cleaning portion 210, the connecting portion 220, and the insertion portion 230 may be an integral structure. The cleaning portion 210 and the connecting portion 220 may be disposed on the side of the insertion portion 230 near the hollow hole 112. Both the cleaning portion 210 and the connecting portion 220 are inclined relative to the insertion portion 230. Additionally, the cleaning portion 210 may protrude relative to the side of the bracket 300 near the hollow hole 112 and the side of the mounting portion 111 near the hollow hole 112, so that the cleaning portion 210 contacts the surface to be cleaned and scrapes away dirt and other contaminants on the surface.

[0071] Combined again Figure 6 The first partition 320, on the side away from the second partition 330, is provided with multiple support ribs 360, which can connect the first partition 320 and the support body 310. On the one hand, the support ribs 360 can improve the structural strength of the support 300 itself, reducing the possibility of deformation and damage to the support 300. On the other hand, the side of the connecting part 220 away from the roller brush cover body 110 can fit against the side of the support rib 360 away from the support body 310, and the support rib 360 provides support for the connecting part 220, improving the stability of the scraper 200 installation.

[0072] In addition, the roller brush cover body 110 also includes a pressing part 113, which can be disposed on the side of the assembly part 111 near the hollow hole 112. The shape of the surface of the pressing part 113 near the scraper 200 can be adapted to the connecting part 220. The pressing part 113 can press against the side of the connecting part 220 away from the support rib 360. Accordingly, the connecting part 220 can be further clamped and fixed by the pressing part 113 and the support rib 360, reducing the possibility of the scraper 200 shaking.

[0073] like Figure 3 and Figure 7 As shown, a limiting platform 221 is also provided on the side of the connecting portion 220 near the cleaning portion 210. The limiting platform 221 can be formed on the side of the connecting portion 220 away from the support rib 360, and is opposite to the end of the pressing portion 113 away from the assembly portion 111. In the embodiment, the end face of the pressing portion 113 away from the assembly portion 111 can abut against the limiting platform 221. On the one hand, it can realize the positioning of the scraper 200 and the roller brush cover body 110 during the assembly process, improving the assembly accuracy and assembly efficiency. On the other hand, the pressing portion 113 can also provide a limit for the scraper 200, reducing the possibility of the cleaning portion 210 being squeezed into the space between the bracket 300 and the roller brush cover 100, so as to ensure that the scraper 200 provides a stable and reliable cleaning function.

[0074] Additionally, the embodiment also provides a surface cleaning device, including a main unit (not shown) and a cleaning mechanism 1000 provided in the embodiment. The cleaning mechanism 1000 is detachably mounted on the side of the main unit near the surface to be cleaned.
