Description

Technical Field

[0001] The utility model belongs to the field of cleaning equipment, and in particular relates to an anti-entanglement type roller brush component based on a left-right structure. Background Art

[0002] At present, common cleaning household appliances on the market, such as vacuum cleaners, mite removers, etc., generally include a roller brush assembly, a motor assembly, and a dust collection assembly, wherein the motor assembly drives the roller brush in the roller brush assembly to keep rotating to brush the surface to be cleaned, and the bristles on the roller brush are used to sweep the dust on the surface to be cleaned toward the suction port of the dust collection assembly, and finally dust suction and dust collection are achieved under the suction force at the suction port.

[0003] However, in actual use, in addition to dust, the surface to be cleaned may also contain long hair shed by the human body in daily life. When the existing roller brush assembly is working, the hair is very easy to be entangled on the surface of the roller brush, and the user needs to remove the roller brush regularly for cleaning. This is not only cumbersome and inconvenient to operate, but also easy to dirty the user's hands, greatly affecting the user experience. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved anti-hair entanglement type roller brush assembly based on a left-right structure.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The invention discloses an anti-hair entanglement roller brush assembly based on a left-right structure, which is installed on a casing formed with a suction port. The roller brush assembly includes a left roller brush and a right roller brush extending left and right respectively, wherein the left roller brush and the right roller brush are respectively rotated from one end to be arranged on the left and right sides of the casing, and are separated from the other end to form an opening connected to the suction port, and the outer diameters of the left roller brush and the right roller brush are respectively gradually reduced from one end to the other end. When brushing, the left roller brush and the right roller brush rotate synchronously, and the hair entangled on the left roller brush and / or the right roller brush gathers from the left and right sides to the middle, and is sucked into the suction port through the opening.

[0007] Preferably, the width of the opening is d, 1mm≤d≤13mm. Under this layout, the cleaning area formed by the left and right roller brushes can be ensured, and the hair wrapped around the left and right roller brushes can be efficiently gathered and absorbed in the middle, ensuring smooth hair collection and avoiding accumulation on the roller brush surface to form knots.

[0008] Preferably, the center line of the opening coincides with the center line of the suction opening.

[0009] According to a specific implementation and preferred aspect of the utility model, the left roller brush and the right roller brush each include a truncated cone-shaped roller brush body, wherein the roller brush body is rotated from the end with a larger diameter to be arranged on the housing, and an opening is formed between the ends with a smaller diameter; the angle between the side of each roller brush body and its own center line is θ, wherein 1°≤θ≤10°. Here, the structure is simple and the processing cost is low.

[0010] Preferably, each roller brush body is further formed with a mounting groove extending spirally around its own center line, and the left roller brush and the right roller brush each include an elastic rubber strip correspondingly mounted in the mounting groove, wherein the rubber strip is arranged outside the mounting groove. Here, by arranging the rubber strip, hair is prevented from being directly entangled on the surface of the roller brush body, and the friction between the hair and the roller brush can be greatly reduced, so as to facilitate the transmission and collection of the hair.

[0011] Specifically, each roller brush body is provided with 3 to 6 mounting grooves, which are distributed in a ring-shaped manner.

[0012] Furthermore, the rotation directions of the left and right mounting grooves are opposite, and the rotation directions of the left and right roller brush bodies are the same. Here, the structure is simple, and it is convenient for hair to converge from the left and right sides along the rotation directions of the corresponding roller brushes to the middle, thereby realizing the collection of hair.

[0013] Preferably, the left roller brush and the right roller brush are arranged symmetrically.

[0014] According to another specific implementation and preferred aspect of the utility model, the left roller brush and the right roller brush each include a magnet correspondingly embedded in the end of the roller brush body with a smaller diameter, wherein the left and right magnets attract each other and keep the centers of the left and right roller brush bodies aligned. Here, the concentricity of the left and right roller brushes is corrected by magnetic force, thereby ensuring the dynamic balance of the roller brushes during rapid rotation.

[0015] In addition, the roller brush assembly also includes a left power module and a right power module, wherein the left power module and the right power module each include a bracket detachably mounted on the housing, a motor disposed on the bracket, and the left roller brush and the right roller brush are respectively connected to the corresponding bracket by rotating from the end, and the left roller brush and the right roller brush are respectively connected to the output shaft of the corresponding motor through a belt. Here, the motor, roller brush and bracket on the same side can be assembled and fixed into an assembly in advance, which is conducive to optimizing the production process and improving the production efficiency of the production line.

[0016] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:

[0017] When the roller brush assembly of the prior art is in use, hair is very easy to be entangled on the surface of the roller brush, and the user needs to remove the roller brush regularly for cleaning. Not only is the operation cumbersome and inconvenient, but it is also easy to dirty the user's hands, greatly affecting the user's experience. The present application designs the structure of the roller brush assembly as a whole, cleverly solving the shortcomings and defects of the prior art. After adopting the roller brush assembly, during cleaning, as the left and right roller brushes rotate, the hair entangled on the left and right roller brushes can be automatically transferred from the left and right sides along the roller brush surface to the middle and converge to the open position. Finally, under the suction force formed by the suction port, the hair passes through the open position and is sucked into the suction port to complete the collection of the hair. Therefore, compared with the prior art, the present invention, on the one hand, effectively prevents the hair from being entangled on the surface of the roller brush by automatically transferring the hair to the middle during cleaning and sucking it into the suction port when it reaches the open position, thereby greatly reducing the frequency of cleaning the roller brush and improving the user experience. On the other hand, the structure is simple, reliable, and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
