Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaner floor brushes, and particularly to an electric floor brush with a roller brush anti-winding design. Background Art

[0002] The working principle of a vacuum cleaner is that an electric motor drives the blades to rotate at a high speed, generating a negative air pressure inside a sealed housing to suck dust debris. The vacuum cleaner achieves the wiping and cleaning of the ground through an electric floor brush.

[0003] When the vacuum cleaner floor brush cleans the ground, the roller brush rotates driven by the motor. During the cleaning process, hair is easily wound around the roller brush, affecting the rotation of the roller brush, resulting in a decline in the cleaning ability of the vacuum cleaner floor brush, and it is inconvenient to clean the hair wound around the roller brush. Summary of the Invention

[0037] Embodiment 1

[0038] Please refer toFigure 1-7 , the present invention provides a technical solution: an electric floor brush with an anti-winding design for a rolling brush, comprising:

[0039] A floor brush body 1, on which a rolling brush cavity 11 is provided. A rolling brush 9 is rotatably installed in the rolling brush cavity 11. A dust suction channel opening 12 is provided in the middle of the rolling brush cavity 11. Symmetrically arranged first scraping tooth groups are provided on both sides of the dust suction channel opening 12. A step surface 13 is provided between the first scraping tooth group and the side wall of the rolling brush cavity 11. The first scraping tooth group includes a plurality of first scraping teeth 14 arranged along the width direction of the floor brush body 1. A first tooth part 141 is provided on the side of the first scraping tooth 14 away from the step surface 13, and the first tooth part 141 contacts the surface of the rolling brush 9;

[0040] A first photoelectric sensor 2, which is provided on the side wall at one end of the rolling brush cavity 11, and the position of the first photoelectric sensor 2 corresponds to the step surface 13.

[0041] One side of the top opening of the rolling brush cavity 11 extends above the step surface 13, so that the step surface 13 and the first scraping tooth group are exposed when the bottom surface of the floor brush body 1 faces upwards, which is convenient for manual cleaning.

[0042] Working principle: When the floor brush of the vacuum cleaner is cleaning the ground, the rolling brush 9 rotates in the rolling brush cavity 11. The first scraping teeth 14 in the rolling brush cavity 11 contact the surface of the rolling brush 9 through the first tooth parts 141, separate the sundries such as hair that may exist on the surface of the rolling brush 9, and accumulate them at the step surface 13, so as to be sucked by negative pressure through the dust suction channel opening 12 or for subsequent cleaning, so as to avoid the decline of the cleaning ability of the floor brush caused by hair being easily wound around the rolling brush. For the sundries separated from the surface of the rolling brush 9 and remaining on the step surface 13, they are monitored by the first photoelectric sensor 2. When the floor brush finishes cleaning, if there are sundries on the step surface 13, the first photoelectric sensor 2 feeds back a control signal to the vacuum cleaner controller for timely cleaning.

[0043] Embodiment 2

[0044] On the basis of the above embodiment, this embodiment further makes the following improved technical solutions: Circular holes 142 are provided on the first scraping teeth 14, and a second photoelectric sensor 3 corresponding to the circular holes 142 in position is also provided on the side wall at one end of the rolling brush cavity 11.

[0045] The second photoelectric sensor 3 can monitor whether there are sundries between two adjacent first scraping teeth 14 through the circular holes 142. When the floor brush finishes cleaning, when the second photoelectric sensor 3 detects that the circular holes 142 are blocked, it feeds back a control signal to the vacuum cleaner controller for timely cleaning of the blockage.

[0046] The cooperation between the second photoelectric sensor 3 and the circular holes 142 also realizes the monitoring of the deformation of the first scraping teeth 14, and timely discovers the damage of the first scraping teeth 14.

[0047] Example 3

[0048] On the basis of the above embodiment, the following technical solutions are further improved in this embodiment: A second scraping tooth group corresponding to the dust suction channel opening 12 in position is further provided on the roller brush cavity 11. The second scraping tooth group includes a plurality of second scraping teeth 15 arranged along the width direction of the floor brush body 1.

[0049] The second scraping teeth 15 are arranged on the side of the first scraping tooth group away from the dust suction channel opening 12, avoiding blocking debris from being sucked into the dust suction channel opening 12, and at the same time further improving the cleaning effect on the roller brush 9.

[0050] Example 4

[0051] On the basis of the above embodiment, the following technical solutions are further improved in this embodiment: A driving module is provided on the floor brush body 1. The driving module includes a driving motor 4, a transmission belt 41 and a transmission cover 42. The output end of the driving motor 4 is connected to the transmission cover 42 through the transmission belt 41. Tooth grooves 421 for meshing with the transmission belt 41 are provided on the surface of the transmission cover 42. Driving teeth 422 are provided on the end face of the transmission cover 42. One end of the roller brush 9 is provided with a driven cover 91, and a plurality of driven teeth 911 arranged circumferentially are provided on the driven cover 91.

[0052] When the roller brush 9 rotates, the driving motor 4 drives the transmission cover 42 to rotate through the transmission belt 41. The driving teeth 422 at the end of the transmission cover 42 are inserted between two adjacent driven teeth 911 to drive the roller brush 9 to rotate.

[0053] A plurality of driven teeth 911 are arranged in a spiral shape along the axis of the roller brush 9. Due to the spiral arrangement of the driven teeth 91, the anti-deformation ability can be improved, making the roller brush 9 not easily stuck, and improving the cutting and scraping ability of the first scraping teeth on the hair on the roller brush 9.

[0054] Three driving teeth 422 arranged circumferentially are provided on the end face of the transmission cover 42, and six driven teeth 911 arranged circumferentially are provided on the driven cover 91, facilitating the clamping connection between the roller brush 9 and the transmission cover 42. And the driving teeth 422 have a trapezoidal structure with a narrower upper part and a wider lower part. This makes it easier for the driving teeth 422 to be stuck between two adjacent driven teeth 911, further facilitating the installation of the roller brush.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
