It is to be understood that the above definitions are merely provided to facilitate understanding of the relative positional relationship of the various components of the cleaning mechanism 1000 and are not to be construed as limiting the present application.

In the embodiment, the cleaning mechanism 1000 is provided, which is applicable to a surface cleaning apparatus, and the cleaning mechanism 1000 can be used for scraping dirt, sewage, and the like on a surface to be cleaned. The surface cleaning device may be one of a device including, but not limited to, a sweeper, a mopping machine, a floor washer, a tabletop cleaning robot, etc., and correspondingly, the surface to be cleaned may be a floor or a tabletop, etc.

As shown in fig. 1, the cleaning mechanism 1000 may include a roll brush cover 100, a wiper strip 200, and a holder 300.

Referring again to fig. 7, the wiper strip 200 may include a cleaning portion 210 and an insertion portion 230. The insertion portion 230 may be disposed at one side of the cleaning portion 210.

Referring to fig. 5 again, the wiper strip 200 may be coupled to one side of the roll brush cover 100 through a bracket 300. Specifically, the support 300 may be fixedly connected to one side of the rolling brush cover 100, and one side of the support 300, which is close to the rolling brush cover 100, may be provided with an insertion groove 340 extending along the first direction. In addition, at least one limiting block 350 is further disposed on a side of the bracket 300 close to the rolling brush cover 100, and the at least one limiting block 350 may be located on the opening structure side of the inserting groove 340. In some embodiments, the first direction may be parallel to the length direction of the cleaning mechanism 1000.

The insertion portion 230 of the wiper strip 200 may be inserted into the insertion groove 340. And the at least one limiting block 350 may be abutted against one side of the plugging portion 230 away from the bottom of the plugging groove 340. In an embodiment, the stopper 350 can limit the engaging portion 230 in the engaging groove 340, so as to prevent the engaging portion 230 from being arbitrarily separated from the engaging groove 340. Thereby, a pre-fixing of the wiper strip 200 to the holder 300 can also be achieved.

In the prior art assembly, the wiper strip 200 is generally directly clamped by the roll brush cover 100 and the bracket 300. In the assembly process, the position of the scraping strip 200 is easy to move, so that the assembly is not in place, the assembly efficiency is low, and the productivity is affected.

In the application, the pre-fixing of the scraping strip 200 and the bracket 300 can be realized firstly, and then the bracket 300 and the rolling brush cover 100 are fixedly installed, so that the positioning installation between every two is conveniently realized. Compared with the prior art, the application can obviously reduce the probability of the offset of the scraping strip 200 relative to the bracket 300 and the rolling brush cover 100, is easier to assemble the scraping strip 200 in place, and correspondingly can improve the assembly efficiency, improve the productivity and reduce the production cost.

As shown in fig. 2 to 4, further, the roll brush cover 100 may include a roll brush cover body 110 and an elastic buckle assembly 120. The rolling brush cover body 110 is provided with a hollow hole 112 for the rolling brush in the surface cleaning device to contact the surface to be cleaned so as to provide the cleaning function for the surface to be cleaned. In addition, an assembling portion 111 may be formed on one side of the rolling brush cover body 110, and the assembling portion 111 may be located on one side of the hollowed-out hole 112 and may extend along the length direction of the cleaning mechanism 1000. In an embodiment, the roll brush cover body 110 may include a proximal side 1102 and a distal side 1101.

The elastic clasp assembly 120 may include a clasp 121, a torsion spring 123, and a pin 122. The lock catch 121 may be disposed through the assembly portion 111 of the rolling brush cover body 110, and may be rotatably connected to the assembly portion 111 through the pin 122. The torsion spring 123 may be sleeved on the pin 122 and respectively abuts against the assembly portion 111 and the lock catch 121. In an embodiment, the torsion spring 123 may be used to drive the latch 121 to reset, and maintain the locked state.

It will be appreciated that the latch 121 may include an integral operating portion 1211 and a snap-fit portion 1212. The operating portion 1211 may protrude with respect to the proximal side 1102 of the fitting portion 111, and the buckling portion 1212 may protrude with respect to the distal side 1101 of the fitting portion 111. In application, the buckling part 1212 can be used for buckling connection with a host of the surface cleaning apparatus, so that the cleaning mechanism 1000 can be connected with the host, and a user can drive the latch 121 to rotate through the operation part 1211, so that the buckling part 1212 is buckled connection or separation with the host.

In an embodiment, the rolling brush cover 100 may include two symmetrical elastic buckle assemblies 120, and the two elastic buckle assemblies 120 may be matched to realize the detachable connection between the cleaning mechanism 1000 and the host.

As shown in fig. 1, 3, 5, and 6, the bracket 300 may include a bracket body 310, a first partition 320, and a second partition 330.

In some embodiments, the bracket body 310 may be fixedly connected to the fitting portion 111 by a screw, and the bracket body 310 may be located at the proximal side 1102 of the roll brush cover body 110. In addition, the bracket body 310 may be provided with a through hole 370 opposite to the elastic buckle assembly 120, and the operating portion 1211 of the latch 121 may be disposed through the through hole 370 and protrudes from a side of the bracket body 310 away from the roller brush cover body 110, so as to be convenient for a user to touch.

In other embodiments, the bracket body 310 may be detachably connected to the mounting portion 111 of the roller brush cover body 110 by a clamping manner. Of course, the bracket body 310 may be connected to the mounting portion 111 by non-detachable connection such as adhesion, riveting, welding, or the like.

In the embodiment, the first partition 320 and the second partition 330 are disposed on one side of the support body 310 close to the roller brush cover body 110, and on one side close to the hollow hole 112. The first partition 320 and the second partition 330 are both parallel to the longitudinal direction and the height direction of the cleaning mechanism 1000 at the same time. In an embodiment, the first partition 320 and the second partition 330 are spaced apart from each other and cooperate to define a mating groove 340 extending in the first direction. Additionally, in some embodiments, the first and second baffles 320, 330 and the bracket body 310 may be a unitary structure, which may be formed by integral injection molding.

The side of the insertion groove 340 near the roll brush cover body 110 may have an opening structure. In the first direction, both ends of the insertion groove 340 may be closed by a structure such as a coaming on the bracket body 310, so that the insertion portion 230 of the wiper strip 200 may be restricted from being randomly shaken in the first direction in the insertion groove 340.

Of course, in other embodiments, both ends of the insertion groove 340 may be closed by a structure such as a shroud on the mounting portion 111.

As shown in fig. 5 and 6, the stopper 350 may be disposed at a side of the second partition 330 near the roll brush cover body 110. And the stopper 350 may protrude with respect to a side of the second partition 330 near the first partition 320, i.e., the stopper 350 may cover a portion of the opening structure of the insertion groove 340. In some embodiments, the stopper 350 may be integrally formed with the second separator 330.

In addition, the distance between the surface of the stopper 350, which is close to the bracket body 310, and the bracket body 310 may be greater than the distance between the surface of the first spacer 320, which is far from the bracket body 310, and the bracket body 310. I.e., the height of the second separator 330, may be greater than the height of the first separator 320. Therefore, a height difference can be formed between the limiting block 350 and the first partition 320, so that the insertion of the insertion portion 230 of the wiper strip 200 into the insertion groove 340 can be facilitated.

In other embodiments, second baffle 330 may also be the same height as first baffle 320. The stopper 350 has a gap between an end remote from the second partition 330 and the first partition 320 to be inserted into the insertion portion 230.

In some embodiments, the bracket 300 may include three stoppers 350, and the three stoppers 350 may be uniformly disposed at a side of the second partition 330 remote from the bracket body 310 along the first direction. Accordingly, the force applied to each portion of the engagement portion 230 is uniform, and the probability that the engagement portion 230 is disengaged from the engagement groove 340 can be reduced.

In other embodiments, the bracket 300 may also include one, four, or six equal numbers of stop blocks 350. When the bracket 300 includes the plurality of stoppers 350, the plurality of stoppers 350 may be uniformly or non-uniformly disposed on the second separator 330 at intervals along the first direction.

Further, three avoidance notches 321 are further formed on the first partition 320, and the three avoidance notches 321 can be set in one-to-one correspondence with the three limiting blocks 350. Specifically, the projection of the avoidance notch 321 on the bracket body 310 and the projection of the corresponding stopper 350 on the bracket body 310 are at the same position in the first direction. On the one hand, when the scraper 200 and the bracket 300 are assembled and disassembled, the operator can insert the inserting portion 230 into the inserting groove 340 or pull out from the inserting groove 340 beyond the limiting block 350 at the corresponding position, so as to apply force to the corresponding position of the scraper 200. On the other hand, when the cleaning mechanism 1000 is cleaned, dirt in the insertion groove 340 can be conveniently cleaned, and the self-cleaning efficiency of the cleaning mechanism 1000 is improved.

As shown in fig. 3 and 7, the insertion portion 230 may have a substantially plate-like structure and be parallel to both the length direction and the height direction of the cleaning mechanism 1000. The inserting portion 230 may be matched with the inserting groove 340, and when the inserting portion 230 is inserted into the inserting groove 340, a circumferential sidewall of the inserting portion 230 may be attached to an inner wall of the inserting groove 340, so as to prevent the inserting portion 230 from shaking in the inserting groove 340. In addition, the three limiting blocks 350 may abut against one side of the plugging portion 230 away from the bottom of the plugging groove 340.

In an embodiment, the wiper strip 200 further includes an engagement portion 220 connected between the cleaning portion 210 and the insertion portion 230. In some embodiments, the cleaning portion 210, the engagement portion 220, and the insertion portion 230 may be a unitary structure. The cleaning portion 210 and the connecting portion 220 may be disposed on a side of the inserting portion 230 near the hollow hole 112. And both the cleaning part 210 and the engagement part 220 are obliquely disposed with respect to the insertion part 230. In addition, the cleaning part 210 may protrude with respect to a side of the holder 300 near the hollowed-out hole 112 and a side of the fitting part 111 near the hollowed-out hole 112 so that the cleaning part 210 contacts the surface to be cleaned, scrapes off dirt or the like on the surface to be cleaned.

Referring to fig. 6 again, a plurality of support ribs 360 are further disposed on a side of the first partition 320 away from the second partition 330, and the plurality of support ribs 360 can be connected between the first partition 320 and the bracket body 310. In one aspect, the supporting ribs 360 can improve the structural strength of the support 300, and reduce the possibility of deformation and damage of the support 300. On the other hand, the side of the connecting portion 220 away from the rolling brush cover body 110 can be attached to the side of the supporting rib 360 away from the bracket body 310, and the supporting rib 360 provides a supporting function for the connecting portion 220, so as to improve the installation stability of the scraping strip 200.

In addition, the rolling brush cover body 110 further includes a pressing portion 113, and the pressing portion 113 may be disposed on a side of the assembling portion 111 near the hollowed-out hole 112. The shape of the pressing portion 113 near the surface of the scraping strip 200 may be adapted to the engaging portion 220. The pressing portion 113 may press against a side of the engagement portion 220 away from the supporting rib 360. Accordingly, the engaging portion 220 can be further clamped and fixed by the pressing portion 113 and the supporting rib 360, so as to reduce the possibility of shaking the scraper bar 200.

As shown in fig. 3 and 7, a limiting table 221 is further disposed on a side of the engaging portion 220 near the cleaning portion 210. The limiting mesa 221 may be formed on a side of the engagement portion 220 away from the supporting rib 360, and opposite to an end of the pressing portion 113 away from the mounting portion 111. In an embodiment, an end surface of the pressing portion 113 away from the end of the assembling portion 111 may abut against the limiting table 221. On the one hand, the positioning of the scraping strip 200 and the rolling brush cover body 110 in the assembly process can be realized, and the assembly precision and the assembly efficiency are improved. On the other hand, the pressing portion 113 may also provide a limit for the scraping strip 200, so as to reduce the possibility that the cleaning portion 210 is pressed between the bracket 300 and the roller brush cover 100, so as to ensure that the scraping strip 200 provides a stable and reliable cleaning function.

In addition, a surface cleaning apparatus is provided in the embodiment, including a host (not shown) and the cleaning mechanism 1000 provided in the embodiment. The cleaning mechanism 1000 is detachably mounted on a side of the main body close to the surface to be cleaned.
