[0002] Vacuum cleaners are cleaning devices widely used in advanced human life and industrial production. They have been developed for more than a hundred years since their birth. The working principle of a vacuum cleaner is to drive the blades to rotate at high speed by an electric motor to generate a negative air pressure in a sealed housing, and then suck dust through an external suction pipe.

[0003] In the current composition structure of vacuum cleaners, the floor brush is a component used for floor cleaning in a vacuum cleaner. When using a vacuum cleaner at home, it is a very common problem that hair is wound around the rotary brush of the floor brush. Since some hair is difficult to clean when wound around the rotary brush, after the user removes the rotary brush later, auxiliary tools such as scissors and blades are needed to cut the hair before the hair can be cleaned from the rotary brush. The cleaning is rather troublesome, reducing the user experience. Summary of the Invention

[0036] Please refer to Figures 1-4 , the present invention provides a technical solution: a blade telescopic roller brush, including a roller brush body 1 and a connecting head 2. A plurality of first mounting grooves 3 and a plurality of second mounting grooves 4 are provided on the roller brush body 1. The connecting head 2 is connected to the roller brush body 1. A blade member 5 is rotatably connected in the first mounting groove 3, and a limiting body 6 is rotatably connected in the second mounting groove 4. Both the blade member 5 and the limiting body 6 are connected to a driving member 7. The driving member 7 includes a micro motor 71 and a swing arm 72. The micro motor 71 is connected to the connecting head 2, and the swing arm 72 is connected to the micro motor 71.

[0037] The first mounting grooves 3 and the second mounting grooves 4 are arranged crosswise on the circumferential side of the roller brush body 1, so that the sawteeth on the limiting body are located between the cutting blades, improving the cutting efficiency and thus enhancing the user experience.

[0038] A first rotation groove 8 is provided in the first installation groove 3. The blade member 5 includes a blade 51 and a first connecting shaft 52. The blade 51 is connected to the first connecting shaft 52, and the first connecting shaft 52 is connected to the swing arm 72. The first connecting shaft 52 is rotatably connected in the first rotation groove 8. This ensures that the first connecting shaft rotates in the first rotation groove. When cutting is not required, the outer sidewall of the cutter is flush with the first installation groove. When cutting is required, the micro-motor drives the first connecting shaft to rotate, causing the cutter to flip out of the first installation groove to cut hair.

[0039] A second rotation groove 9 is provided in the second installation groove 4. The limiting body 6 is provided with a second connecting shaft 10 and a plurality of saw teeth 11. The second connecting shaft 10 is rotatably connected in the second rotation groove 9. This ensures that the second connecting shaft rotates in the second rotation groove. When cutting is not required, the outer sidewall of the saw teeth is flush with the second installation groove. When cutting is required, the micro-motor drives the second connecting shaft to rotate, causing the saw teeth to flip out of the second installation groove to limit the hair, facilitating cooperation with the cutter to cut the hair.

[0040] Sensors 12 are provided on both the limiting body 6 and the blade 51. When the sensors sense hair entanglement, they immediately transmit signals to the controller to start the micro-motor to rotate, thereby cutting the hair.

[0041] A controller 13 is provided on the micro-motor 71. The controller controls the flipping out of the blade and the saw teeth to limit and cut the hair.

[0042] Both the first installation groove 3 and the second installation groove 4 are inclinedly arranged on the roller brush body 1.

[0043] A fixing block 14 is provided on the micro-motor 71, and the fixing block 14 is fixedly connected to the connecting head 2. This improves the stability of the entire structure.

[0044] Working principle: By setting a first mounting groove and a second mounting groove on the roller brush body, the micro-motor is connected to the connector, the blade member is rotatably connected to the first mounting groove, the limiting body is rotatably connected to the second mounting groove, the motor is connected to the connector, the connecting shaft passes through the connector and is connected to the swing arm, and several swing arms are respectively connected to the first connecting shaft and the second connecting shaft. When there is no hair entanglement on the roller brush body, the outer walls of the limiting body and the blade are flush with the first mounting groove and the second mounting groove respectively. When hair is entangled, the saw teeth on the blade and the limiting body are stressed, and the sensors on the blade and the limiting body transmit signals to the controller. The controller controls the operation of the motor. The motor starts and the top blade and the saw teeth rotate, so that the blade and the saw teeth extend out of the roller brush. The saw teeth limit the hair, and the blade extends out to cut the hair, thus achieving the purpose of automatically cutting the hair and improving the user experience. At the same time, both the first mounting groove and the second mounting groove are inclined on the roller brush body, and the first mounting groove and the second mounting groove are cross-arranged on the circumferential side of the roller brush body, so that the saw teeth on the limiting body are located between the cutting knives, improving the cutting efficiency.

[0045] 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 and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
