The main body has a buckling position for installing the roller brush 20 and a separation position for removing the roller brush. The roller brush can drive the main body from the separation position to the buckling position through the cooperation of the first assembly part and the main body. At this time, the elastic component accumulates elastic restoring force to switch the main body to the separation position; in the process of switching the main body from the buckling position to the separation position, the second assembly part drives the first assembly part to separate from the main body.

[0007] In one embodiment, the body is configured to generate magnetic attraction with the first assembly portion.

[0008] In one embodiment, the elastic assembly includes a first elastic member and a second elastic member, the first elastic member is elastically connected between the shell and the body along a first direction, and the second elastic member is connected between the shell and the body along a second direction, the first direction intersects the second direction, and the second direction is parallel to and opposite to the assembly direction of the first assembly portion;

[0009] When the body is switched to the buckling position, the first elastic member accumulates a first elastic force to drive the body along the first direction, and the second elastic member accumulates a second elastic force to drive the body along the second direction. The elastic restoring force includes the first elastic force and the second elastic force.

[0010] In one embodiment, the body includes a mounting groove and an assembly opening communicating with the mounting groove, the first assembly portion enters the mounting groove from the assembly opening and cooperates with the body, and the groove wall of the mounting groove is inclined relative to the plane where the assembly opening is located;

[0011] When the main body switches from the buckled position to the separated position, the groove wall of the installation groove pushes the first assembly part to disengage from the installation groove.

[0012] In one embodiment, the body includes a first half block and a second half block, both of which have an arc-shaped opening. The first half block and the second half block are spliced ​​with the openings facing each other to define a mounting groove and an assembly opening.

[0013] The inner walls of the arc-shaped openings in the first half block and the second half block are tilted downward in the direction of approaching each other in the assembly direction of the first assembly part, and the second half block abuts against the first assembly part when the main body switches from the buckled position to the separated position.

[0014] In one embodiment, the second elastic member includes a supporting portion and an elastic portion, the elastic portion is connected between the supporting portion and the housing along the second direction, and the other end of the supporting portion is slidably connected to the body.

[0015] In one embodiment, the housing includes a first end cover, one axial end of the roller brush is rotatably connected to the first end cover, and the first assembly portion is provided on an outer edge of the first end cover;

[0021] According to another aspect of the present application, a cleaning device is further provided, comprising a body and a floor brush assembly according to any one of the above embodiments, wherein the floor brush assembly is connected to the body through a shell.

[0022] The above-mentioned floor brush assembly has a first assembly portion provided at one axial end of the roller brush, a second assembly portion provided on the shell, and an elastic assembly of the second assembly portion elastically connected between the shell and the body. When the axial end of the roller brush assembly moves toward the side close to the body and the first assembly portion and the second assembly portion engage, the body moves from a detached position separated from the roller brush to a buckled position assembled with the roller brush. During the movement of the body, a force is applied to the elastic assembly, causing the elastic assembly to deform and accumulate an elastic restoring force that switches the body to the detached position. When the mating relationship between the first assembly portion and the second assembly portion disappears, the elastic restoring force acts on the body, causing the body to move and push the first assembly portion away from the body until the body returns to the detached position, thereby completing the disassembly of the roller brush. In this way, the roller brush is easy to disassemble, and with the help of the elastic restoring force, the roller brush is easy to disassemble, saving time and effort.

[0035] See Figure 1 The present application provides a cleaning device 1000, including a floor brush assembly 100 and a body. One end of the body is connected to the floor brush assembly 100, and the other end forms a handle for convenient operation of the cleaning device 100, thereby achieving cleaning of the floor through the floor brush assembly 100.

[0036] Specifically, see Figures 2 to 5 The present application provides a floor brush assembly 100, including a shell 10, a roller brush 20 and a second assembly part 30. The roller brush 20 has a first assembly part 22 at one axial end, and the second assembly part 30 is arranged in the shell 10. The second assembly part 30 includes a body 31 and an elastic component 32. The body 31 has a buckling position for installing the roller brush 20 and a separation position for removing the roller brush 20. The elastic component 32 is elastically connected between the shell 10 and the body 31. The roller brush 20 can drive the body 31 from the separation position to the buckling position through the cooperation between the first assembly part 22 and the body 31. At this time, the elastic component 32 accumulates elastic restoring force to switch the body 31 to the said separation position.

[0037] Furthermore, when the body 31 switches to the buckling position, the second assembly portion 30 drives the first assembly portion 22 to separate from the body 31 .

[0038] In this way, when one axial end of the roller brush 20 moves toward the side close to the main body 31 and makes the first assembly part 22 and the second assembly part 30 cooperate, the main body 31 moves from the separation position separated from the roller brush 20 to the buckled position assembled with the roller brush 20, and in the process of movement, a force is applied to the elastic component 32, causing the elastic component 32 to deform and accumulate elastic restoring force to switch the main body 31 to the separation position.

[0039] When the matching relationship between the first assembly part 22 and the second assembly part 30 disappears, the elastic restoring force accumulated in the elastic component 32 acts on the main body 31, the main body 31 moves, and pushes the first assembly part 22 to separate from the main body 31 until the main body 31 returns to the separation position. The first assembly part 22 is completely separated from the main body 31, thereby completing the disassembly of the roller brush 20. In this way, the disassembly of the roller brush 20 is simple, and with the help of the elastic restoring force, the disassembly of the roller brush 20 is simple, time-saving and labor-saving.

[0040] Specifically, the user can hold one axial end of the roller brush 20 and move the first assembly portion 22 toward the side close to the body 31 until it mates with the second assembly portion 30, thereby assembling the roller brush 20 to the housing 10. When the roller brush 20 needs to be removed, the mating relationship between the first assembly portion 22 and the second assembly portion 30 is canceled. At this time, under the action of the elastic restoring force, the body 31 can automatically switch back to the separated position, and push the first assembly portion 22 to easily detach from the body 31, thereby completing the removal of the roller brush 20.

[0041] Furthermore, the roller brush 20 has a first fixing portion at one end close to the first assembly portion 22, and a second fixing portion on the shell 10. When the first assembly portion 22 cooperates with the second assembly portion 30, the first fixing portion and the second fixing portion are limitedly engaged, thereby completely fixing the roller brush 20 on the shell 10.

[0042] In one embodiment, the first fixing portion can be a protrusion or groove provided along one axial end of the roller brush 20, and the second fixing portion can be a groove or protrusion provided in cooperation with the protrusion or groove. When the first assembly portion 22 is matched with the second assembly portion 30, the protrusion is inserted into the groove and realizes a radially limited snap connection with the groove of the roller brush 20.

[0043] When the roller brush 20 needs to be disassembled, an external force is applied to disengage the protrusion from the groove, and then the first assembly portion 22 is disengaged from the second assembly portion 30, thereby conveniently disassembling the roller brush 20. It can be understood that since the roller brush 20 needs to clean the bottom surface, the first fixing portion can rotate around the axial direction of the roller brush 20 within the second fixing portion.

[0044] In one embodiment, the first assembly portion 22 and the second assembly portion 30 may be matched with each other by suction, contact, or the like. For example, the first assembly portion 22 is configured to generate magnetic attraction with the second assembly portion 22 .

[0045] The shorter the distance between the first assembly part 22 and the second assembly part 30, the greater the magnetic force between the two. Therefore, when the user moves the first assembly part 22 toward the side of the main body 31, not only is there an external force applied (provided by the user), but the second assembly part 30 itself also applies an attractive force to the first assembly part 22, making the assembly of the roller brush 20 more labor-saving. The user can apply a smaller force, and the force required for other assembly is provided by the magnetic force.

[0046] In one embodiment, the mating state of the first assembly part 22 and the second assembly part 30 can be that the first assembly part 22 and the second assembly part 30 are magnetically fitted. At this time, the first fixing part and the second fixing part cooperate with each other. Under the dual action, during the cleaning operation of the floor brush assembly 100, the roller brush 20 is prevented from accidentally detaching from the shell 10, thereby improving the installation firmness of the roller brush 20.

[0047] In addition, during the operation of the floor brush assembly 100, the two magnets continuously attract each other, which can reduce the shaking of the roller brush 20 during operation and reduce the noise generated by the shaking of the roller brush 20 during operation.

[0048] In one embodiment, the elastic component 32 includes a first elastic member 321 and a second elastic member 322, the first elastic member 321 is elastically connected between the shell 10 and the main body 31 along a first direction L1, and the second elastic member 322 is connected between the shell 10 and the main body 31 along a second direction L2, the first direction L1 intersects with the second direction L2, and the second direction L2 is parallel to and opposite to the assembly direction L3 of the first assembly portion 22.

[0049] When the body 31 switches to the buckled position, the first elastic member 321 accumulates a first elastic force driving the body 31 along the first direction L1, and the second elastic member 322 accumulates a second elastic force driving the body 31 along the second direction L2. The elastic restoring force includes the first elastic force and the second elastic force.

[0050] When the first assembly part 22 approaches the main body 31 along a set direction until it abuts against the main body 31, the main body 31 will drive the first elastic member 321 to deform until the second assembly part 30 and the first assembly part 22 are completely opposite in the assembly direction L3 of the first assembly part 22, and then the first assembly part 22 continues to move toward the side close to the second assembly part 30 until the second assembly part 30 drives the second elastic member 322 to deform until the main body 31 moves to the buckled position, and at this time the first fixing part and the second fixing part are limited at the same time.

[0051] Specifically, when the first assembly portion 22 approaches the main body 31 in a predetermined direction, the main body 31 stretches the first elastic member 321, generating a first elastic force in the first direction L1 that propels the main body 31 to its original position. Subsequently, the main body 31 compresses the second elastic member 322, generating a second elastic force in the second direction L2 that propels the main body 31 to the separated position. Once the external force acting on the main body 31 is removed, the combined action of the first and second elastic forces causes the main body 31 to switch to the separated position, simultaneously pushing the first assembly portion 22 away from the main body 31 during this switching process.

[0052] It can be understood that in this embodiment, the separation position of the main body 31 is located at the upper left corner of the buckle position. In other embodiments, the separation position of the main body 31 can also be set to the upper right corner of the buckle position, and the user only needs to operate one axial end of the roller brush 20 straight up and down.

[0053] In one embodiment, when the separation position of the main body 31 is located at the upper left corner of the buckle position, when the main body 31 switches from the buckle position to the separation position, it moves toward the upper left corner under the action of the first elastic force and the second elastic force, and in the process of moving toward the upper left corner, pushes the first assembly part 22 to leave the installation groove 311.

[0054] In this way, the present application can not only achieve time-saving and labor-saving disassembly, but also achieve time-saving and labor-saving installation.

[0055] In one of the embodiments, if there is no magnetic effect between the main body 31 and the first assembly part 22, the same time-saving and labor-saving effect as in the present application cannot be achieved when assembling the roller brush 20. When disassembling the roller brush 20, the main body 31 can still push the roller brush 20 away from the main body 31 while moving toward the upper left corner, thereby achieving labor-saving disassembly.

[0056] In one embodiment, the second elastic member 322 includes a supporting portion 3221 and an elastic portion 3222 . The elastic portion 3222 is connected between the supporting portion 3221 and the housing 10 along the second direction L2 . The other end of the supporting portion 3221 is slidably connected to the body 31 .

[0057] The support portion 3221 can lift the first assembly portion 22 along the second direction L2 under the action of the elastic portion 3222. At the same time, under the action of the first elastic member 321, the first assembly portion 22 can be driven to slide along the first direction L1 on the support portion 3221. The setting of the support portion 3221 can avoid the elastic portion 3222 from getting stuck or failing, so that the first assembly portion 22 can run smoothly.

[0058] In one embodiment, the main body 31 includes a mounting groove 311 and an assembly opening 312 connected to the mounting groove 311. The first assembly portion 22 enters the mounting groove 311 from the assembly opening 312 and cooperates with the main body 31. The groove wall of the mounting groove 311 is inclined relative to the plane where the assembly opening 312 is located.

[0059] When the body 31 switches from the fastening position to the separating position, the groove wall of the installation groove 311 pushes the first assembly portion 22 to disengage from the installation groove 311 .

[0060] Specifically, the groove wall of the installation groove 311 forms an inclined surface 31a. When the main body 31 switches from the buckled position to the separated position, when the main body 31 moves along the first direction L1, the inclined surface 31a abuts and cooperates with the first assembly part 22 and guides the first assembly part 22 to gradually slide out of the installation groove 311.

[0061] In one embodiment, the body 31 includes a first half block 313 and a second half block 314 , both having an arc-shaped opening. The first half block 313 and the second half block 314 are spliced ​​with the openings facing each other to define a mounting groove 311 and an assembly opening 312 .

[0062] Among them, the inner walls of the arc-shaped openings of the first half block 313 and the second half block 314 are tilted downward in the direction of approaching each other in the assembly direction L3 of the first assembly part 22, and the second half block 314 abuts against the first assembly part 22 when the main body 31 switches from the buckled position to the separation position. The first elastic member 321 is connected between the second half block 314 and the shell 10, and the first half block 313 is used to guide and push the first assembly part 22 to disengage from the installation groove 311.

[0063] Specifically, the size of the mounting groove 311 gradually decreases from the assembly opening 312 (i.e., the groove opening) to the bottom of the groove, and the assembly opening 312 is the largest. On the one hand, it can facilitate the assembly of the first assembly part 22. On the other hand, it allows the inclined surface 31a formed by the first half block 313 to abut and guide the first assembly part 22, making it easier to push the first assembly part 22 out of the mounting groove 311.

[0064] Furthermore, the shell 10 includes a baffle 14, which is arranged inside the shell 10. One end of the first elastic member 321 is connected to the baffle 14, and the other end is connected to the outer wall of the second half block 314 away from the mounting groove 311, thereby realizing the movement of the main body 31 relative to the main body 31 in the first direction L1 and the second direction L2.

[0065] In one embodiment, the shell 10 includes a first end cover 21, one axial end of the roller brush 20 is rotatably connected to the first end cover 21, the first assembly portion 22 is provided at the outer edge of the first end cover 21, and the first end cover 21 is controlled to move toward the body 31 to drive the first assembly portion 22 to cooperate with the second assembly portion 30.

[0066] The first end cap 21, as part of the housing 10, is directly connected to one axial end of the roller brush 20. The roller brush 20 can be lifted or lowered by operating the first end cap 21, thereby installing or removing the roller brush 20. Furthermore, after the roller brush 20 is installed, it can rotate relative to the first end cap 21 to clean the floor.

[0067] Furthermore, the floor brush assembly 100 also includes a driving member, the shell 10 includes a second end cover, the other axial end of the roller brush 20 is rotatably connected to the second end cover, and the driving member is drivingly connected to the roller brush 20 on one side of the second end cover; the driving member is used to drive the roller brush 20 to rotate relative to the shell 10.

[0068] During assembly, the roller brush 20 can be first assembled on the end connected to the driver. That is, the user can operate the second end cap to connect one axial end of the roller brush 20 to the driver. At this point, the roller brush 20 is assembled to the housing 10. Then, the user operates the first end cap 21 to assemble the other axial end of the roller brush 20 to the housing 10 until the first assembly portion 22 and the second assembly portion 30 engage, thus completing the fixation of the roller brush 20. It is understood that for disassembly, the user can simply reverse the operation.

[0069] The floor brush assembly 100 and cleaning device 1000 provided in the present application can not only realize the easy disassembly of the roller brush 20, saving time and effort, but also realize the easy installation of the roller brush 20 under the action of magnetic attraction, saving time and effort.

[0070] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
