Description

Roller brush for sweeper and sweeper

Technical Field

The utility model relates to a cleaning device technical field especially relates to a machine round brush and machine of sweeping floor sweeps floor.

Background

The cleaning of a middle sweeping rolling brush rod of a sweeper in the market at present has two modes, one mode is that a cutting structure is arranged at a position, close to a rolling brush, on the sweeper, the cutting structure is in contact with the rolling brush, and the winding object is cut in the movement of the rolling brush. Another is to design an auxiliary tool for manually cleaning the roll brush by removing the roll brush from the body and then cleaning the roll brush with the auxiliary tool.

However, since the length of the rolling brush is generally over 10cm, when the rolling brush is axially cleaned, the auxiliary tool needs to be cleaned from one end of the rolling brush to the other end of the rolling brush, so that the winding materials need to be gradually removed from one end of the rolling brush to the other end of the rolling brush, and the winding materials are gradually accumulated due to the long length of the rolling brush, so that the cleaning difficulty is increased. Therefore, Chinese patent CN101999859A proposes a roller structure of a brush head of a dust collector, and specifically, the roller structure is divided into a first roller and a second roller, the second roller is a differential roller, and teeth are arranged on the periphery of a thin shaft and are matched with the inner diameter of the first roller. When the structure is disassembled, any roller needs to be screwed to a certain angle to complete the disassembly, so that the structure is relatively troublesome to disassemble and assemble.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a machine round brush and machine of sweeping floor can solve the problem among the prior art.

Specifically, the utility model provides a machine round brush sweeps floor, including the round brush stick, the round brush stick is equipped with the first connecting portion that are the corner post type including the first brush stick and the second brush stick of coaxial setting on the first brush stick, is equipped with the interior concave part that holds first connecting portion on the second brush stick, is equipped with the second connecting portion of being connected with first connecting portion magnetism including the concave part. The rolling brush rod is configured into a multi-section structure, the rolling brush is convenient to disassemble through magnetic connection, and meanwhile, the rolling brush is prevented from being relatively separated in the process of rotating and cleaning garbage.

In an embodiment, the first connecting portion and/or the second connecting portion are/is a magnet.

In a technical scheme, be equipped with the external screw thread on the first connecting portion, be equipped with the internal thread in the interior concave part, utilize first connecting portion to be connected first brush stick and second brush stick through threaded connection and fix together, strengthen the firm intensity of connection, improve transmission efficiency.

In one technical scheme, the rolling brush rod further comprises bristles, and the bristles are spirally distributed from the first brush rod to the second brush rod along the axial direction of the rolling brush rod.

The utility model also provides a sweeper, including the roller brush for sweeper in any preceding technical scheme.

Compared with the prior art, the beneficial effects of the utility model reside in that: the traditional long rolling brush is made into a rolling brush formed by connecting a plurality of sections of brush rods, and the plurality of sections of brush rods are connected together through magnetic connection, so that the rolling brush is prevented from being relatively separated in use; meanwhile, the roller brush is easy to disassemble into a single section for cleaning, and the problem that the cleaning difficulty of the long roller brush is high is effectively solved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the present application provides a sweeper 10, which moves on a floor through a moving wheel set 400 disposed on a chassis, wherein a roller brush driven by a motor to rotate is further disposed on the chassis, and the roller brush contacts with the floor to complete a cleaning operation. Wherein the roll brush includes a first brush bar 100 and a second brush bar 200 that are magnetically coupled together.

Specifically, as shown in fig. 2, 3 and 4, the roll brush includes a first brush bar 100 and a second brush bar 200 which are coaxially disposed and linked, a first connection portion 101 having a corner post shape is provided on the first brush bar 100, an inner recess portion 201 for accommodating the first connection portion 101 is provided on the second brush bar 200, and a second connection portion 202 magnetically connected to the first connection portion 101 is provided on the inner recess portion 201. The rotating force of the first brush bar 100 or the second brush bar 200 driven by the motor to rotate is transmitted to the other brush bar through the first connecting part 101 of the corner column type, so that the integral equidirectional rotation of the roll brush is realized; meanwhile, the first brush bar 100 and the second brush bar 200 can be prevented from being relatively separated during the rotation of the roll brush for cleaning the garbage by the magnetic connection between the first connection part 101 and the second connection part 202.
