Referring to fig. 1, the present application provides a vacuum cleaner including a floor brush assembly 100. The floor brush assembly 100 comprises a housing 10, a rolling brush 20, a first magnetic member 30, a second magnetic member 40 and a driving assembly 50, wherein the housing 10 is used for providing an installation basis for the rolling brush 20, the first magnetic member 30 and the driving assembly 50, the driving assembly 50 is used for driving the rolling brush 20 to rotate relative to the housing 10, and the first magnetic member 30 and the second magnetic member 40 are matched for assembling the rolling brush 20 to the housing 10.

Referring to fig. 2 and 3, the rolling brush 20 includes a rolling brush body 21 and a fixed shaft 23 rotatably connected to one end of the rolling brush body 21. The driving assembly 50 includes a driving member 51 and a transmission shaft 53, the driving member 51 is coupled to the housing 10, one end of the transmission shaft 53 is in transmission connection with the driving member 51, and the roller brush body 21 is sleeved on and fixed to the other end of the transmission shaft 53 away from the driving member 51. The first magnetic member 30 is coupled to the housing 10, and the second magnetic member 40 is coupled to the fixed shaft 23 and arranged with the first magnetic member 30 in sequence along the axial direction of the fixed shaft 23. The fixed shaft 23 is fixed to the housing 10 by a magnetic attraction force between the first magnetic member 30 and the second magnetic member 40. Preferably, the axial direction of the fixed shaft 23, the axial direction of the roll brush body 21, and the axial direction of the transmission shaft 53 all coincide.

When the vacuum cleaner is in operation, the driving member 51 drives the transmission shaft 53 to drive the roller brush main body 21 to rotate relative to the fixed shaft 23 and the housing 10, so that the roller brush main body 21 can perform a cleaning operation on a surface to be cleaned. In order to ensure that the roller brush 20 has a good cleaning effect during each cleaning operation, the roller brush 20 needs to be periodically disassembled and cleaned. In the present application, since the fixing shaft 23 is fixed to the housing 10 by the magnetic attraction between the first magnetic member 30 and the second magnetic member 40, when the roller brush 20 needs to be cleaned, a large downward detaching force is applied to the roller brush 20, and the fixing shaft 23 is separated from the housing 10 and the transmission shaft 53 is separated from the roller brush body 21 by the detaching force, so that the roller brush 20 can be detached. As can be seen, the dust collector and the floor brush assembly 100 thereof can be assembled and disassembled without any disassembling tool, so that the dust collector has the characteristic of convenient disassembly and assembly.

Referring to fig. 4, 5 and 6, further, the housing 10 is provided with a rolling brush cavity 11 and a position avoiding opening 12, the position avoiding opening 12 is located below the rolling brush cavity 11 and is communicated between the rolling brush cavity 11 and the outside, and the cavity wall of the rolling brush cavity 11 is provided with a clamping through groove 13 with a downward notch. The roller brush main body 21 of the holding through groove 13 is partially positioned in the roller brush cavity 11, the rest part extends out of the roller brush cavity 11 through the avoiding opening 12 and contacts with the surface to be cleaned, and the fixed shaft 23 is held in the holding through groove 13. It can be understood that the surface to be cleaned is located below the floor brush assembly 100, and the avoiding opening 12 and the notch of the clamping through groove 13 are arranged facing the surface to be cleaned. By providing the retaining through groove 13, the reliability of connection between the roller brush 20 and the housing 10 can be further improved, so that the installation of the roller brush 20 is more stable. Moreover, since the notch of the holding through groove 13 and the avoiding opening 12 are both arranged downward, the roller brush body 21 and the fixed shaft 23 can be respectively moved out of the avoiding opening 12 and the notch of the holding through groove 13 and separated from the housing 10 under the action of the detaching force, so that the roller brush 20 has better convenience in detachment and installation.

Of course, the mounting manner of the fixed shaft 23 is not limited to the above one. In other embodiments, the fixing shaft 23 may be completely located in the rolling brush cavity 11 and fixed by the first magnetic member 30 and the second magnetic member 40 disposed on the inner wall of the rolling brush cavity 11.

Referring to fig. 5 again, the clamping through slot 13 includes a clamping section 131 and a guiding section 133 sequentially disposed and communicated along the gravity direction, the clamping section 131 is in interference fit with the fixing shaft 23, and the diameter of the guiding section 133 is greater than the diameter of the fixing shaft 23 and gradually increases along the gravity direction. During the assembly of the roller brush 20, the guiding section 133 can guide and limit the fixed shaft 23, so as to facilitate the operation of gradually approaching the fastening section 131 and finally fixing the fixed shaft 23 in the fastening section 131.

Further, the holding through groove 13 further includes an elastic section 135, and the elastic section 135 is communicated with one end of the guiding section 133 far away from the clamping section 131. When the fixing shaft 23 is clamped in the clamping through groove 13, the caliber of the elastic section 135 is smaller than the diameter of the fixing shaft 23, and the caliber of the elastic section 135 is increased under the pressing of the fixing shaft 23. It is understood that the elastic section 135 has a certain elasticity, and the caliber of the elastic section 135 can be increased or decreased by an external force.

When the fixing shaft 23 is held in the holding section 131 in the holding through groove 13, the elastic section 135 is not subjected to an external force and has a diameter smaller than the diameter of the fixing shaft 23. Therefore, when the fixing shaft 23 is separated from the clamping section 131 by gravity and passes through the elastic section 135, the fixing shaft 23 is difficult to be separated from the elastic section 135 due to a large friction force between the elastic section 135 and the fixing shaft 23. Therefore, the fixed shaft 23 can be still maintained in the holding through groove 13 and can rotate relative to the roller brush body 21. When the roller brush 20 needs to be disassembled, under the action of the disassembling force, the elastic section 135 can be increased under the abutting pressure of the fixing shaft 23, and then the fixing shaft 23 can be moved out of the clamping through groove 13, so that the roller brush 20 can be disassembled.

Referring to fig. 6 again, in some embodiments, the first holding space 16 is formed in the housing 10, and the first magnetic member 30 is held in the first holding space 16. Compared with other methods of fixing the first magnetic member 30 by using the mounting member, the method of assembling the first magnetic member 30 in the first holding space 16 is simpler, and the number of used parts is less, so that the assembling efficiency of the first magnetic member 30 can be effectively improved.

It should be noted that the first holding space 16 may be a part of the space inside the rolling brush chamber 11, or may be a separate space outside the rolling brush chamber 11. Preferably, the first catching space 16 is independent from the outside of the brush chamber 11 to prevent the first magnetic member 30 from interfering with the rotation of the brush main body 21.

Further, the housing 10 includes an upper shell 14 and a lower shell 15, and the upper shell 14 and the lower shell 15 are detachably abutted and enclosed to form the rolling brush cavity 11. The lower case 15 is formed with a first holding space 16, a loading and unloading opening 17 and a holding through groove 13, and the loading and unloading opening 17 is communicated between the first holding space 16 and the outside and is used for allowing the first magnetic member 30 to enter and exit the first holding space 16. When the upper case 14 and the lower case 15 are butted against each other, the upper case 14 covers the loading/unloading port 17.

Specifically, when the upper shell 14 and the lower shell 15 are butted to form the housing 10, the first magnetic member 30 can be sealed in the first holding space 16. Thus, the first magnetic member 30 is prevented from falling from the loading/unloading port 17. When the upper shell 14 and the lower shell 15 are disassembled, the first magnetic member 30 can enter and exit the first holding space 16 from the loading and unloading opening 17, so that the first magnetic member 30 has better assembly simplicity.

In some embodiments, the second holding space 232 is formed in the fixed shaft 23, and the second magnetic member 40 is held in the second holding space 232. Compared with other methods of fixing the second magnetic member 40 by using an assembly member, the method of clamping the second magnetic member 40 in the second clamping space 232 is simpler, and fewer parts are used, so that the assembly efficiency of the second magnetic member 40 can be effectively improved.

Referring to fig. 3 again, further, the end surface of the fixing shaft 23 facing the first magnetic member 30 is recessed to form a second holding space 232, so that when the second magnetic member 40 is held in the second holding space 232, the second magnetic member 40 does not occupy the space of the floor brush assembly 100. As such, the compactness of the floor brush assembly 100 can be improved, so as to facilitate the miniaturization of the floor brush assembly 100. Moreover, since the second holding space 232 is formed by the end surface of the fixed shaft 23 being recessed, the second magnetic member 40 can be operated to enter and exit the second holding space 232 from the opening of the recessed portion, so as to facilitate the assembly and disassembly of the second magnetic member 40.

In some embodiments, the first magnetic member 30, the second magnetic member 40 and the fixing shaft 23 are coaxially disposed. It is understood that the magnetic central axes of the first magnetic member 30 and the second magnetic member 40, which are coaxially disposed, are also overlapped and extend in the axial direction of the fixed shaft 23. In this way, the fixed shaft 23 can be stably fixed to the housing 10 by the first magnetic member 30 and the second magnetic member 40, and the roller brush body 21 can be conveniently rotated with respect to the fixed shaft 23.

In the vacuum cleaner and the floor brush assembly 100 thereof, the fixed shaft 23 is fixed to the housing 10 by the magnetic attraction between the first magnetic member 30 and the second magnetic member 40. When it is necessary to detach the roll brush 20, the fixed shaft 23 is separated from the housing 10 by directly applying a large downward detaching force to the roll brush 20, and the roll brush 20 can be separated from the housing 10 by the detaching force. As can be seen, the dust collector and the floor brush assembly 100 thereof can be assembled and disassembled without any disassembling tool, so that the dust collector has the characteristic of convenient disassembly and assembly.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
