"substantially" means within an acceptable error range, and a person skilled in the art can solve the technical problem within a certain error range to substantially achieve the technical effect.

Furthermore, the term "coupled" is intended to include any direct or indirect coupling. Thus, if a first device couples to a second device, that connection may be through a direct connection, or through an indirect connection via other devices. The following description is of the preferred embodiment of the present invention, and is made for the purpose of illustrating the general principles of the invention and not for the purpose of limiting the invention. The protection scope of the present invention is subject to the limitations defined by the appended claims.

It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

A cleaning device such as a cleaner is a novel cleaning tool for cleaning household sanitation, and the principle of the cleaning device is that water is sprayed on the surface to be cleaned to accelerate the molecular motion speed of a dirt surface, dirt on the dirt surface is absorbed by a suction nozzle by destroying the binding force between the dirt surface and the surface to be cleaned, and stubborn dirt, oil stain and the like are eliminated. Fig. 1 is a schematic structural diagram of a cleaning device provided by an embodiment of the present invention. Referring to fig. 1, in particular, the cleaner may comprise a main body 100 and an accessory assembly 200, wherein a suction nozzle 2111 is provided at an end of the accessory assembly 200 away from the main body 100, and the suction nozzle 2111 is used for sucking dirt on a dirty surface. Power equipment for generating vacuum suction may be provided in the main body 100, and the dirt sucked from the suction nozzle 2111 is sucked to the main body 100 through the attachment assembly 200.

In the prior art, when the cleaning machine works, solid matters such as pet hair, paper scraps and the like can be sucked more or less, and in a long term, the solid matters are easy to block in narrow channels such as pipelines of the cleaning machine, so that the use effect of the cleaning machine is influenced, and the user experience is seriously reduced.

The embodiment of the utility model provides a for solving above-mentioned current situation, provide a cleaning device's annex brush. Fig. 2 is an exploded view of an attachment brush of a cleaning device according to an embodiment of the present invention; fig. 3 is a sectional view of an attachment brush of a cleaning device according to an embodiment of the present invention. Fig. 7 is a cross-sectional view of an accessory assembly of a cleaning device according to an embodiment of the present invention. Referring to fig. 2 to 3 and fig. 7, the accessory brush of the cleaning apparatus provided in the present embodiment is configured to communicate with the main body 100, and the accessory brush 210 includes: an attachment brush body 210a, and a filter assembly 213.

A sealing member 215 may be provided between an outer wall of the front end 211 and an inner wall of the rear end 212, and the sealing member 215 may seal a gap between the front end 211 and the rear end 212 in a dirt flow direction, whereby dirt inhaled from the suction nozzle 2111 does not flow to the main body 100 from the gap between the front end 211 and the rear end 212. The sealing element 215 may be fixedly disposed on the outer wall of the front end 211 or fixedly disposed on the inner wall of the rear end 212, as shown in fig. 2, and preferably, the sealing element 215 in this embodiment is fixedly disposed on the outer wall of the front end 211, which is less difficult to process than the sealing element disposed on the inner wall of the rear end 212. The sealing element 215 can be a rubber sealing element, which has good sealing effect and good corrosion prevention effect.

It is understood that, as an alternative embodiment, the rear end 212 may be inserted into the front end 211, as long as the cavity 214 is formed therebetween, and the present invention is not limited thereto.

Further, the accessory brush 210 may further include two connection buckles 216, and in this embodiment, it is preferable that the number of the connection buckles 216 is two, and the two connection buckles 216 may be symmetrically disposed on two opposite outer walls of the front end 211. The connecting buckle 216 may have a latching portion 2161 thereon, a mating portion 2162 on the inner wall of the rear end 212 for mating with the latching portion 2161, and the latching portion 2161 mates with the mating portion 2162 to relatively latch the front end 211 to the rear end 212. As shown in fig. 2, specifically, the locking portion 2161 may be a protrusion disposed on the outer wall of the front end 211, and correspondingly, the matching portion 2162 may be a groove disposed on the inner wall of the rear end 212, and further, in order to facilitate the protrusion to be locked into the groove, a guiding surface M may be disposed on the end of the locking portion 2161 away from the suction nozzle 2111 to guide the protrusion to be locked into the groove more smoothly, and the guiding surface M may be a slope or a cambered surface.

Of course, it is also possible to reverse the snap-in part 2161 to be a recess provided on the outer wall of the front end 211 and correspondingly the mating part 2162 to be a protrusion formed on the inner wall of the rear end, it being understood that in this case, a guide surface (not shown in the figures) may be provided on the mating part 2162.

One end of the connecting buckle 216 is rotatably disposed at the front end 211, preferably, as shown in fig. 2, one end of the connecting buckle 216 may be hinged to the front end 211, the other end of the connecting buckle 216 forms an operating portion 2163, and the operating portion 2163 is used for receiving an external force to relatively separate the buckle portion 2161 from the mating portion 2162. Specifically, the user can press the operation parts 2163, so that the operation parts 2163 are close to the front end 211, and when there are two oppositely arranged connecting buckles 216, the user presses the two operation parts 2163, so that the two operation parts 2163 are relatively close, the clamping parts 2161 on the connecting buckles 216 gradually disengage from the matching parts 2162, and then the front end 211 is pulled out from the rear end 212, so that the front end 211 and the rear end 212 can be detached. The front end 211 and the rear end 212 are connected through the connecting buckle 216, the connecting buckle 216 can be conveniently detached, the cleaning efficiency of a user is improved, time is saved, and the use is convenient. The acceptance and the convenience of the user to the cleaning equipment are improved.

It is understood that the connecting buckle 216 may be a plastic member having a certain elasticity, or the hinged end of the connecting buckle 216 may be provided with a torsion spring, so that it is ensured that the connecting buckle 216 can be operated and moved by the operation part 2163 within a certain range, and in the clamping state, the clamping state can be maintained more stably.
