[0021] Embodiment: As shown in FIGS. 1 to 4, the present invention discloses an embodiment of a floor brush for a vacuum cleaner that does not entangle hair, including a floor brush base 100 that can reciprocate on a surface to be cleaned and has a rotating brush chamber 120, a floor brush cover 200 connected to the floor brush base 100, and a rotating brush body 300 positioned within the rotating brush chamber 120 in the axial direction. The rotating brush body 300 includes a first brush strip 360 located on the outside and a second brush strip 364 provided at an interval from the first brush strip 360 and made of a different material from the first brush strip 360. The first brush strip 360 rotates around the axis of the rotating brush body 300 to form a first brush strip virtual rotation circle, and the second brush strip 364 rotates around the axis of the rotating brush body 300 to form a second brush strip virtual rotation circle. The diameter of the second brush strip virtual rotation circle is equal to or greater than the diameter of the first brush strip virtual rotation circle.

[0022] The rotating brush body 300 further includes a rotating brush sleeve 320 located inside, a driving end 304 provided at one end, a plurality of mounting portions 340 provided at intervals in the circumferential direction surrounding the rotating brush sleeve 320, and a plurality of circumferential gaps 342 located between two adjacent mounting portions 340. The mounting portion 340 includes a first mounting groove 344 for accommodating the first brush strip 360 and a second mounting groove 348 provided adjacent to the first mounting groove 344 for accommodating the second brush strip 364. The extending directions of the first mounting groove 344 and the second mounting groove 348 are parallel to the central direction of the rotating brush body 300. The axial cross-sections of the first mounting groove 344 and the second mounting groove 348 are T-shaped grooves. The first brush strip 360 is a hair strip, includes a plurality of hairs, the diameter of the hairs is 0.1 - 0.6 mm, and a nylon fiber material is used. The second brush strip 364 is a silicon rubber strip, and a rubber material is used. The circumferential width of the first brush strip 360 is larger than the circumferential width of the second brush strip 364. The axial cross-sections of the first brush strip 360 and the second brush strip 364 are T-shaped, and the non-contact ends of the first brush strip 360 and the second brush strip 364 are both located at the bottom of the T-shaped groove. The thickness of the non-contact end of the first brush strip 360 is smaller than the thickness of the non-contact end of the second brush strip 364. The diameter range of the virtual rotation circles of the first and second brush strips is preferably 10 - 60 mm. The width of the second brush strip 364 is 0.5 - 30 mm.

[0023] This embodiment further includes a connection head 400 connected to the floor brush base 100 and the floor brush cover 200 and having a connection head passage 420, a connection air duct 140 with one end communicating with the rotating brush chamber 120 and the other end communicating with the connection head passage 420, a sawtooth portion 104 provided in the rotating brush chamber 120 and adjacent to the rotating brush body 300, and a transmission mechanism 500 with one end connected to the driving end 304 to drive the rotating brush body 300 to rotate. The sawtooth portion 104 is provided at intervals along the axial direction of the rotating brush body 300 and includes a plurality of comb teeth capable of contacting the first brush strip 360 or the second brush strip 364, and the comb teeth are provided toward the rotating brush body 300. The connection head 400 is rotatable relative to the floor brush base 100 and is connected to one end of the telescopic tube or hose of the vacuum cleaner, and the other end of the telescopic tube or hose of the vacuum cleaner is connected to the vacuum cleaner body. The transmission mechanism 500 includes a transmission gear or a transmission belt with one end connected to the output of the floor brush motor.

[0024] During operation, at the high-speed rotation of the floor brush motor, the first brush strip 360 and the second brush strip 364 of the rotating brush body 300 rotate accordingly to strike the cleaning target surface to generate a dust-containing airflow. The dust-containing airflow enters the rotating brush chamber 120, enters the connection air duct 140 through the opening at the rear side of the rotating brush chamber 120, and further flows in the direction of the dust cup of the vacuum cleaner body through the connection head passage 420, and finally is filtered and discharged to the outside. Since the length along the diameter direction of the second brush strip 364 is larger than the length along the diameter direction of the first brush strip 360 and it is a silicon rubber strip with excellent elasticity, in the rotation direction of the rotating brush body 300, the first brush strip 360 contacts the sawtooth portion 104 earlier than the second brush strip 364, so that the hair can be loosened and spread from the comb teeth, reducing entanglement and enabling absorption. Thereby, the cleaning ability is improved because the hair is not entangled.

[0025] The advantage of this invention is that it can effectively loosen and spread the hair entangled around the rotating brush body, which helps the hair to be combed out by the comb teeth and sucked, preventing the hair from getting entangled, improving the cleaning ability, and ensuring the reliability of the operation of the floor brush motor.

[0026] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereto. Those skilled in the art can make various modifications and improvements without departing from the creative concept of the present invention, and all of these belong to the protection scope of the present invention.
