The present disclosure relates to the technical field of vacuum cleaners, in particular to a cyclonic propping anti-hair-winding roller brush body, a floor brush and a vacuum cleaner.
In a working process of a vacuum cleaner, hair and other dirt are first transported to a dust extraction port of the vacuum cleaner under the rotation of a floor brush, and meanwhile, the dirt is sucked away under a continuous negative pressure suction of the vacuum cleaner.
However, in a process of dust collection, the hair is very prone to being wound onto a transmission part of a roller brush body with the rotation of the roller brush body, which may cause burning of a motor in serious cases.
In order to solve the above technical problem, the present disclosure provides a cyclonic propping anti-hair-winding roller brush body. In a rotation process of a roller brush, hair can be propped and whirled to one side away from the roller brush body, and at the same time, with the help of a dust collection force of a vacuum cleaner, the hair can be quickly sucked away without being wound on the roller brush body. Therefore, the amount of the hair entering transmission components is reduced to the greatest extent.
The cyclonic propping anti-hair-winding roller brush body of the present disclosure includes a roller brush main body, a plurality of cleaning ribs which are arranged separating from each other are arranged on a surface of the roller brush main body, a flow guide groove is formed in a side face of at least one side of the cleaning ribs, the flow guide groove is formed in the side face of the cleaning ribs in a length direction of the roller brush main body, and the flow guide groove is formed in a side facing an area where dirt enters the roller brush main body; and when the roller brush main body rotates, the dirt is capable of entering the flow guide groove and being rotated under an action of the flow guide groove, so as to form a cyclone and prop the dirt. According to the roller brush body of the present disclosure, the flow guide groove is formed in the side facing the hair and other dirt, therefore, when the roller brush main body rotates, the hair is driven to hit the flow guide groove and whirl under a guiding action of the flow guide groove, so that a cyclonic mode is generated when a roller brush rotates at a high speed, the generated cyclone props the hair outwards, so as to prevent the hair from being naturally wound on the roller brush, and at the moment that the hair is suspended in a vacuum chamber of a dust collection housing of the vacuum cleaner under the action of cyclonic propping, the hair is directly sucked into a dust cup by the vacuum cleaner, thereby achieving an effect of no hair winding.
Further, a groove bottom of the flow guide groove is arc-shaped, planar or V-shaped.
Further, the cleaning ribs are spirally arranged on the surface of the roller brush main body.
Furthermore, each cleaning rib includes a first rib body and a second rib body, and an included angle formed by intersection of extension lines at ends, close to each other, of the first rib body and the second rib body is not 180 degrees.
Further, the cleaning ribs are arranged in an axial direction of the roller brush main body.
Further, the cleaning ribs are linear or curved.
The present disclosure further provides a floor brush, including the aforementioned cyclonic propping anti-hair-winding roller brush body.
Furthermore, the floor brush further includes a backflow piece located at an end part of a roller brush main body, the backflow piece includes at least one group of backflow parts, each backflow part includes a lead-in area and a reflux area, and the reflux area is used to redirect dirt entering the lead-in area and move it towards a middle area of the roller brush main body.
Furthermore, a plurality of first block edges are further arranged on one side of the backflow piece away from an axial center of the roller brush main body, and the floor brush further includes second block edges which are staggered and coaxially arranged with the first block edges.
The present disclosure further provides a vacuum cleaner, including the aforementioned floor brush.

The preferred embodiments of the present disclosure are described in detail below in combination with accompanying drawings, so that advantages and features of the present disclosure can be more easily understood by those skilled in the art, and the scope of protection of the present disclosure can be more clearly defined.
Referring to
In some implementations, the flow guide groove 1111 is formed in the side face of the cleaning ribs 11 in a length direction of the roller brush main body 1, and the flow guide groove 1111 is formed in a side facing an area where dirt enters the roller brush main body 1. When the roller brush main body 1 rotates, the dirt can enter the flow guide groove 1111 and move towards a direction away from the surface of the roller brush main body under an action of the flow guide groove 1111.
Referring to
Therefore, according to a vacuum cleaner provided with the roller brush main body 1 of the present disclosure, since the opening of the flow guide groove 1111 faces the side faces of the cleaning ribs 11, that is, when the roller brush rotates, the hair and other dirt hit head-on in the flow guide groove 1111, so that under the action of the flow guide groove 1111, a cyclonic mode is generated when the roller brush rotates at a high speed, the generated cyclone props the hair and other dirt, so as to prevent the hair from being naturally wound on the roller brush main body 1, the roller brush main body 1 cannot be wound, then, at the moment that the hair is suspended in a vacuum chamber under the action of cyclonic propping, the hair is directly sucked into a dust cup by the vacuum cleaner, thereby achieving an effect of no hair being wound on the surface of the roller brush main body 1.
In some implementations, each cleaning rib 11 includes a body 111 and a soft scraping layer (not drawn in the figure), and the soft scraping layer may be any material with a scraping function, such as fluff, brush hair or leather strips. The soft scraping layer may be embedded on the body 111 or covered on the surface thereof.
A first face 1112 is a face where a surface of each body 111 away from one side of the roller brush main body 1 is located. In some implementations, the first face 1112 is a cylindrical face coaxially arranged with the roller brush main body 1, thereby facilitating mold opening and processing of the roller brush main body 1. The first face 1112 of each cleaning rib 11 may be on the same cylindrical face or on different cylindrical faces, that is, distances between the first face 1112 of each body 111 and an outer surface of the roller brush main body 1 are different. In other possible implementations, the first face 1112 may also be a curved face or an inclined face.
Referring to
In some implementations, the cleaning ribs 11 are spirally arranged on the surface of the roller brush main body 1.
Each cleaning rib 11 may include a first rib body 1113 and a second rib body 1114 which are mutually connected, and an included angle formed by intersection of extension lines at ends, close to each other, of the first rib body 1113 and the second rib body 1114 is not 180 degrees. Referring to
The first rib body 1113 and the second rib body 1114 may be mutually connected or not connected, and when the two are mutually connected, they together form a V shape, a C shape with an outward opening, a herringbone shape, a shape like a Chinese character “ru” or an arc shape. When the first rib body 1113 and the second rib body 1114 may be not mutually connected, they together form a splay shape.
The first rib body 1113 and the second rib body 1114 of each cleaning rib 11 may also be arranged in an integrated and through mode, that is, the second rib body 1114 continues to rotate in a spiral direction of the first rib body 1113, and an extension line of one end of the first rib body 1113 close to the second rib body 1114 mutually coincides with an extension line of one end of the second rib body 1114 close to the first rib body 1113. That is, the cleaning ribs 11 are spirally arranged from one end of the roller brush main body 1 to the other end of the roller brush main body 1 step by step.
In other implementations, the cleaning ribs 11 may also be arranged in an axial direction of the roller brush main body 1. For example, the cleaning ribs may be arranged in a direction parallel to an axis of the roller brush main body 1, or an overall arrangement direction is in the axis direction of the roller brush main body 1, but the cleaning ribs are wavy or tooth shaped. Therefore, it is convenient for dust and other dirt to gather at a bottom of a wave or tooth.
The present embodiment is a floor brush, including the cyclonic propping anti-hair-winding roller brush body in embodiment 1.
The floor brush of the present embodiment further includes a backflow piece 2 located at an end part of the roller brush main body 1. Referring to
In some implementations, each lead-in area 211 is correspondingly connected to one flow guide groove 1111. Therefore, even if a small amount of hair remains in the flow guide groove 1111 and moves to the lead-in area 211 without being propped, it can also be blocked by the reflux area 212 for backflow in time.
In some implementations, there are the plurality of backflow parts 21 which are sequentially connected and arranged at the end part of the roller brush main body 1 in a circular mode, and an arrangement direction of each backflow part 21 is arranged in a circumferential direction of the end part of the roller brush main body 1.
Referring to
In some implementations, the backflow parts 21 may be arranged on an end cover 4, the end cover 4 has a mounting edge 41 extending towards a middle of the roller brush main body 1, and the backflow parts 21 are arranged on the mounting edge 41 sequentially. The first block edges 31 are arranged on an outer side face of the end cover 4 away from the roller brush main body 1. Correspondingly, a connecting cover 5 covering the end cover 4 partially is arranged, and the second block edges 32 are arranged on one side of the connecting cover 5 close to the roller brush main body 1.
The present embodiment is a vacuum cleaner, including the floor brush in embodiment 2.
