[0002] A vacuum cleaner is a must-have device in most households. Its main principle is to use an electric motor to drive the rotating blades to rotate at high speed, creating negative pressure inside the blades, which sucks the dust on the ground into the interior. There is no need to use a broom to sweep, making it convenient for users to clean the house. The floor brush is an important part of the vacuum cleaner. The floor brush includes a suction port for collecting dust and other garbage. Different floor brushes are equipped with bristles / rollers, etc., which can sweep up dust and stubborn garbage.

[0003] However, during the use of the existing vacuum cleaner floor brush, since the roller brush is a component that directly contacts the surface to be cleaned, it is very easy to get entangled with foreign objects such as hair. If these hairs are not cleaned in time, they are likely to fall and float during subsequent cleaning, which will affect the subsequent cleaning of the vacuum cleaner and reduce the cleaning effect of the vacuum cleaner. Therefore, there is a special need for a vacuum cleaner floor brush that can prevent hair entanglement. Utility Model Content

[0004] The purpose of the utility model is to provide a vacuum cleaner floor brush that prevents hair entanglement, so as to solve the problem that the existing vacuum cleaner floor brush proposed in the above background technology is that during use, since the roller brush is a component that directly contacts the surface to be cleaned, it is very easy to produce the problem of foreign matter such as entanglement.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] See also Figure 1-Figure 8 As shown, the utility model provides a technical solution: a vacuum cleaner floor brush for preventing hair entanglement, comprising a box cover 1, a roller 4, a brush 5 and a cutting assembly 6, wherein a roller 2 is rotatably connected to the outer wall of the bottom end of the box cover 1, a motor 3 is fixedly connected to the outer wall of one end of the box cover 1, a roller 4 is fixedly connected to the outer wall of one end of the motor 3, a brush 5 is bonded to the outer wall of the roller 4, and a cutting assembly 6 is arranged on the inner wall of the roller 4;

[0029] The cutting assembly 6 includes a protective sleeve 601, a rotating shaft 602, a transmission shaft 603, a transmission block 604, a blade 605, a ball 606 and a groove 607. The protective sleeve 601 is fixedly connected to the outer wall of the drum 4, the rotating shaft 602 is rotatably connected to the outer wall of the drum 4, the transmission shaft 603 is rotatably connected to the outer wall of the rotating shaft 602, and one end of the transmission shaft 603 is fixedly connected to the box cover 1, the transmission block 604 is fixedly connected to the outer wall of the transmission shaft 603, the blade 605 is slidably connected to the outer wall of the transmission block 604, the ball 606 is rotatably connected to the inner wall of the blade 605, and the protective sleeve 601 is fixedly connected to the outer wall of the drum 4. A groove 607 is provided on the outer wall. When in use, the floor brush of the vacuum cleaner is first placed in the designated position, and then the outer wall power supply is connected to start the motor 3 to drive the roller 4 to rotate on the surface of the box body 1, so that the brush 5 on the surface of the roller 4 cleans the floor. When the hair is entangled with the surface of the brush 5, the rotation of the roller 4 drives the blade 605 to slide on the surface of the transmission block 604, so that the blade 605 can perform telescopic movement inside the protective cover 601. When the blade 605 extends out of the roller 4 and enters the interior of the protective cover 601, it can cut off the hair entangled on the surface of the brush 5, so that the hair falls off from the surface of the brush 5 and enters the interior of the vacuum cleaner through the box cover 1.

[0030] In this embodiment, the cross-section of the transmission shaft 603 is an elliptical shape. When the drum 4 rotates, the transmission shaft 603 always remains stationary inside the drum 4. The rotation of the drum 4 can convert the rotational motion of the blade 605 on the surface of the transmission shaft 603 into a linear motion of the blade 605 inside the protective sleeve 601, so that the blade 605 can automatically cut the hair.

[0031] In this embodiment, the blade 605 is slidably connected to the inside of the protective sleeve 601 through the transmission shaft 603. Through the design of the protective sleeve 601, when the blade 605 is extended outward, the blade 605 will not slide out of the protective sleeve 601, so that the protective sleeve 601 protects the blade 605 and prevents the blade 605 from scratching the ground when extending outward and causing damage to the surface of the blade 605.

[0032] In this embodiment, the blade 605 is slidably connected to the transmission block 604 via ball bearings 606 , and multiple groups of ball bearings 606 are arranged on the outer wall of the blade 605 . The design of ball bearings 606 can improve the smoothness of the blade 605 sliding on the surface of the transmission block 604 .

[0033] In this embodiment, the outer wall of the groove 607 is an inclined surface. Through the setting of the groove 607, when the hair is entangled on the surface of the protective cover 601, the hair can slide into the interior of the groove 607 along the inclined surface of the groove 607, thereby promoting the cutting efficiency of the blade 605 on the hair.

[0034] In this embodiment, the rollers 2 are arranged in multiple groups on the outer wall of the bottom end of the box cover 1, and the rollers 2 are symmetrically arranged with respect to the central axis of the box cover 1. The design of the rollers 2 can promote the stability of the box cover 1 moving on the ground.

[0035] Working principle: When in use, first place the vacuum cleaner brush in the designated position, then connect the outer wall power supply to start the motor 3 to drive the roller 4 to rotate on the surface of the box body 1, so that the brush 5 on the surface of the roller 4 cleans the floor. When the hair is entangled with the surface of the brush 5, the roller 4 rotates on the surface of the transmission shaft 603, and the transmission shaft 603 always remains stationary inside the roller 4. The cross-section of the transmission shaft 603 is an elliptical shape. Through the rotation of the roller 4, the rotational motion of the blade 605 on the surface of the transmission shaft 603 can be converted into a linear motion of the blade 605 inside the protective cover 601, so that the blade 605 can perform telescopic motion inside the protective cover 601. When the blade 605 extends out of the roller 4 and enters the inside of the protective cover 601, it can cut off the hair entangled on the surface of the brush 5, so that the blade 605 automatically cuts the hair, so that the hair falls off the surface of the brush 5 and enters the inside of the vacuum cleaner through the box cover 1, thus completing the use process of a vacuum cleaner floor brush that prevents hair entanglement.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
