As shown in fig. 3, the rolling brush structure is widely applied to cleaning devices, and in mite removing instruments and dust collectors, the rolling brush is driven by a motor to rotate, so as to sweep up the garbage and dust on the surface to be cleaned, and the garbage and dust are sucked into a dust collecting box by a fan in the cleaning device.

As shown in fig. 1-2, the bottom of the mite killing apparatus a has a mounting groove K for accommodating the rolling brush structure R, the rolling brush structure R is rotatably connected between two groove walls of the mounting groove K, and a fence-shaped panel T for allowing air flow and dirt to pass through is arranged outside the mounting groove K. The rolling brush structure acts on the surface of the object to be cleaned through the window P of the fence-shaped panel T.

As shown in fig. 3-5, the rolling brush structure R includes a roller 100 and a plurality of soft rubber strips 10 disposed on the surface of the roller 100; the soft rubber strip 10 is composed of a plurality of mutually independent film units 1 which are arranged in a straight line, and a spacing groove 2 is arranged between the adjacent film units 1.

It should be noted that the film unit 1 extends outwards from the surface of the roller 100, and the plane of the film unit 1 is at a first angle with the tangent plane of the surface of the roller 100 at the corresponding position. The filming unit 1 extends along the above-described straight line in its longitudinal direction.

Compared with the traditional bristles, the rubber sheet unit 1 keeps the elastic deformation capacity of the original bristles, can contact the surface of an object to be cleaned and realizes the cleaning of dirt; moreover, the fabric does not have sharp ends and is soft as a whole, so that the fabric cannot be punctured or hooked, and the protection of the object to be cleaned is facilitated; the film unit 1 is convenient to form and simple to assemble with the roller 100, and can be integrally formed even through processes of integral injection molding, insert injection molding, in-mold injection molding and the like, and the film unit 1 and the roller 100 are good in fixing reliability, so that the film unit can be effectively prevented from being separated from the roller 100, and the cleaning effect of the rolling brush is guaranteed.

Compared with the whole soft rubber, the film units 1 are mutually independent and are provided with the spacing grooves 2, so that the film units 1 have better support and resetting capability. Each film unit 1 can be better attached to different heights of the surface to be cleaned of bed sheets and sofas, and further the cleaning effect is improved.

Preferably, the angle of the first included angle is 70 to 90 degrees, and more preferably 90 degrees. First contained angle is 90 degrees and can be so that when roller 100 rotated, film unit 1 acted on the surface of treating the cleaning thing along the tangential direction of effect circumference, and it is bigger to clean the effort, and it is better to clean the effect.

Preferably, the flexible strip 10 in each line is composed of 6-12 film units 1 arranged independently of each other, and a spacing groove 2 is arranged between the adjacent film units 1.

Preferably, the width of the spacing groove 2 is between 3mm and 6 mm. The spacing grooves 2 not only independently open the film units 1, but also provide gaps for air flow to pass through when the film units 1 have independent deformation capacity, and improve the cleaning effect. But the spacing grooves 2 also facilitate cleaning of the roller brush when hair is wound around the roller 100.

Preferably, the film unit 1 on each strip 10 corresponds to the film unit 1 of the adjacent strip 10 so that the spacer grooves 2 are on the same circumference.

Preferably, as shown in fig. 6, the film unit 1 is a TPU material. The roller 100 includes a sleeve 3 coated on the outside and a metal shaft 4 on the inside. The shaft sleeve 3 is made of TPU material and is integrally formed with the film unit 1, so that the soft rubber strip 10 and the roller 100 form an integral structure, and the firmness of the soft rubber strip 10 is further ensured.

The metal shaft 4 is arranged to strengthen the supporting strength of the roller 100 and ensure the connection stability between the rolling brush and the host components such as the mite removing instrument, the dust collector and the like.

In the molding mode, the metal shaft 4 can be plugged into the shaft sleeve 3 after the shaft sleeve 3 and the soft rubber strip 10 are subjected to injection molding. Preferably, plugs 5 are further provided at both ends of the sleeve 3 to limit the metal shaft 4 from being separated from the sleeve 3.

In addition, the shaft sleeve 3 and the soft rubber strip 10 on the outer surface can be integrally molded outside the metal shaft 4 in a metal insert mode, so that the process is simplified, and the production efficiency is high.

The metal shaft 4 and the sleeve 3 are radially fixed to each other, so that the sleeve 3 and the soft rubber strip 10 rotate in the circumferential direction along with the rotation of the metal shaft 4. Preferably one end of the metal shaft 4 is driven by a motor to make the roller brush rotatable.

As shown in fig. 6, preferably, the center of the shaft sleeve 3 is a through hole a with a circular cross section, the metal shaft 4 is a circular rod matched with the through hole a, the periphery of the metal shaft 4 is provided with a longitudinal connecting rib b protruding outwards, the through hole a of the shaft sleeve 3 is provided with a linear groove c matched with the connecting rib b, and the connecting rib b is embedded into the linear groove c, so that the radial rotation between the metal shaft 4 and the shaft sleeve 3 is limited.

As shown in fig. 3-5, four soft rubber strips 10 distributed linearly are arranged outside the roller 100, and two adjacent soft rubber strips 10 form a 90-degree included angle. Four soft adhesive tape 10 symmetries evenly distribute outside roller bearing 100, and four soft adhesive tape 10 are 1/4 circle's mode, and when the round brush rotated, soft adhesive tape 10 waited to clear up the surface in proper order and scraped the brush, owing to distribute evenly, the round brush just more steady when rotating.

As shown in fig. 4, the film unit 1 includes a film body 11 and a support member supporting the film body, the support member having a thickness greater than that of the film body. The support member is a film frame 12 located at the edge of the film body 11, and the film frame 12 has a thickness greater than that of the film body 11. The film body 11 has a thickness of about 1-2 mm and the film frame 12 has a thickness of about 2-3 mm, and the film frame 12 has a better supporting force and wear resistance than the film body 11.

More preferably, the filming unit 1 has a square sheet-like structure. The film unit is in a sheet shape, has good flexibility, can be completely restored to an original state after the external acting force is eliminated.

Under the action of the film units 1, dust and other garbage can be more easily gathered at the concave film main body 11 of each film unit 1 and absorbed by the sweeper, and the disposable dust removal rate is further improved.

In addition to the embodiment provided in this embodiment, it is also proposed that the film units 1 outside the roller 100 can be distributed along a curve, which can be a spiral line spaced from each other. The spiral line can increase the relative area of the film unit 1 and improve the cleaning efficiency.

Alternatively, the film units 1 may be distributed not along a straight line or a curved line but scattered outside the roller 100.
