Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1-4, the utility model provides an antiwind mechanism, it includes:

a sleeve 1 having a hollow mounting cavity; the screw shaft 2 is arranged in the mounting cavity and can rotate relative to the sleeve 1; the screw shaft 2 is composed of a shaft body 21 and a screw rib plate 22 arranged on the outer peripheral surface of the shaft body 21.

As an embodiment of the present invention, the screw shaft 2 may be fixedly disposed, specifically, one end of the screw shaft 2 is inserted into the sleeve 1 through the rotating shaft, and the other end is fixed through the fixing block 20; thus, the sleeve 1 can support one end portion of the screw shaft 2, and the mounting structure between the two is optimized.

The screw shaft 2 can also be rotatably arranged, specifically, the sleeve 1 is rotationally driven by a first driver, the screw shaft 2 is rotationally driven by a second driver, and of course, the sleeve 1 and the screw shaft 2 can also be simultaneously driven to rotate by the same driver through a transmission piece; the sleeve 1 and the screw shaft 2 may be rotated in opposite directions to realize relative rotation therebetween, or they may be arranged to rotate in the same direction but have different rotational angular velocities to realize relative rotation therebetween. In order to save the production cost, it is preferable to fixedly arrange the screw shaft 2.

Further, the sleeve 1 is provided with one or more open ports 10; when long foreign materials such as hair, wool, fluff, etc. are wound around the sleeve 1, they can come into contact with the spiral rib 22 through the opening 10. Because the spiral rib plate 22 and the sleeve 1 rotate relatively, the spiral rib plate 22 can push the wound foreign matters along the axial direction of the spiral shaft 2.

The opening 10 has edges 101 extending in the longitudinal direction of the sleeve 1, and at least one of the edges 101 is provided with serrations 3. As shown in fig. 1 and 2, in some embodiments of the present invention, the edge 101 may be parallel to the axis of the sleeve 1, i.e., the arrangement direction of the saw teeth 3 may be parallel to the axial direction of the sleeve 1 and the screw shaft 2. Fig. 4 is another assembly schematic of the screw shaft and the sleeve in the present application. As shown in fig. 4, in other embodiments of the present application, the edge 101 (the arrangement direction of the saw teeth 3) may also be at an angle with respect to the axis of the sleeve 1, i.e. not parallel to the axial direction of the sleeve 1 and the screw shaft 2, i.e. the edge 101 may be an arc-shaped edge at an angle with respect to the axis of the sleeve 1.

In the above embodiments, the foreign matter wound around the sleeve 1 is caught between the saw teeth 3; when the sleeve 1 rotates relative to the screw shaft 2, the screw rib plates 22 can push foreign matters, and meanwhile, the cutting edges 31 formed on the saw teeth 3 can be matched with the screw rib plates 22 on the screw shaft 2 to cut off the foreign matters, so that the foreign matters can be conveniently removed. Specifically, as shown in fig. 1, 2, and 4, in some embodiments of the present invention, the serrations 3 may be disposed on the edge 101 of the opening 10.

Under specific application scene, sawtooth 3 can be metal material, also can be other stereoplasm materials such as plastics, do not do the injecing in this application, can satisfy the cutting requirement to winding the foreign matter can. In order to reduce the production cost, the saw-tooth 3 and the sleeve 1 are preferably made of the same material and are manufactured by an integral molding process.

Further, the cross section of the saw teeth 3 may be triangular (triangular prism shape as a whole), or may be trapezoidal, rhombic, or rectangular. In order to allow foreign matter to be easily caught between the saw teeth 3, the saw teeth 3 are preferably triangular prism-shaped, one corner of which faces the outer peripheral surface of the sleeve 1, and the other two corners are arranged as the cutting edge 31.

Still further, the serrations 3 may be equally spaced or may have unequal spacing. In view of the above, when the sleeve 1 rotates relative to the screw shaft 2, the saw teeth 3 can reciprocate relative to the screw rib 22, that is, the saw teeth 3 repeatedly contact and separate from the screw rib 22, so that the wound foreign matter can be cut off.

In a specific application scenario, the open port 10 is provided in a long shape along the axial direction of the screw shaft 2, and other positions on the outer circumferential surface of the sleeve 1 are arranged as the attachment surface 11 for cleaning the ground.

Since the open port 10 of the sleeve 1 cannot clean the ground, the number of the open ports 10 is not large enough to satisfy both the cleaning capability of the sleeve 1 and the foreign matter cutting capability; in this embodiment, two openings 10 are provided for mounting the saw teeth 3, and a row of saw teeth 3 is disposed on each of both sides of the opening 10 in the rotational direction.

As an embodiment of the present invention, an insertion hole 12 is formed at one end of the sleeve 1, and the screw shaft 2 can be installed in the installation cavity through the insertion hole 12; by the mode, the installation between the two is more convenient. Further, a bearing is installed at one end of the shaft body 21 close to the fixed block 20, an inner ring of the bearing is in contact with the shaft body 21, and an outer ring of the bearing is in contact with the sleeve 1, so as to rotatably support the sleeve 1.

It will be appreciated that the anti-wind mechanism in the present application may be applied to a roller brush. Wherein, the rolling brush comprises the anti-winding mechanism and bristles for cleaning the ground. Specifically, the bristles may be fixed to the mounting surface 11 by bonding, tufting, or the like.

Further, the roll brush in the present application may be applied to an automatic cleaning apparatus. Wherein, the automatic cleaning equipment comprises the roller brush and is used for cleaning and treating foreign matters; and includes a bottom case for mounting the roll brush, on which a dust suction port capable of absorbing foreign matters is formed.

Specifically, the sleeve 1 is rotatably embedded in the bottom shell and used for cleaning and treating foreign matters; the screw shaft 2 can be fixed in the bottom shell through the fixing block 20, and can also rotate under the action of a driver, and the requirement of rotating relative to the sleeve 1 can be met.

In summary, by providing the sleeve 1, the screw shaft 2 and the saw teeth 3, the foreign matter wound on the sleeve 1 can be pushed while relatively rotating until the foreign matter is cut off by the edge angle 31 on the saw teeth 3. The cut foreign matters are rolled into the dust suction port of the automatic cleaning equipment by the rolling brush, so that the anti-tangling cleaning effect is realized.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application suitable for this invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and illustrations shown and described herein, without departing from the general concept defined by the claims and their equivalents.
