[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure. The working principle of a vacuum cleaner is that the vacuum cleaner motor rotates at high speed, sucking air from the suction port to create a certain vacuum in the dust box. The dust enters the dust filter bag in the dust box through the roller brush, connecting pipe, handle, hose and main suction pipe, and the dust is retained in the dust filter bag. The filtered air then passes through a layer of filter sheet and enters the motor. This layer of filter sheet is a protective barrier to prevent the dust bag from breaking and being sucked into the motor. The air entering the motor flows out through the motor.

[0003] The use of a roller brush can help the vacuum cleaner remove impurities adhering to the ground so that they can be better sucked into the dust filter bag. The vacuum cleaner pipe is usually set in the middle of the roller brush, where the suction is the strongest. However, the impurities removed by the common roller brush cannot be well gathered in the middle, making it difficult for the vacuum cleaner pipe to suck the impurities at the edge of the roller brush into the vacuum cleaner, affecting the vacuuming effect. In addition, the end caps at both ends of the roller brush are generally integrated with the roller brush, resulting in a large weight of the roller brush, which will cause excessive waste of materials when replacing it. Summary of the invention

[0004] The purpose of the present application is to provide a spiral combined roller brush to solve the problem proposed in the above-mentioned background technology that the vacuum cleaner connecting pipe is generally arranged in the middle of the roller brush, where the suction force is the largest, and the impurities cleaned out by the common roller brush cannot be well gathered in the middle, making it difficult for the vacuum cleaner connecting pipe to suck the impurities at the edge of the roller brush into the inside of the vacuum cleaner, affecting the vacuuming effect, and the end covers at both ends of the roller brush are generally an integrated structure with the roller brush, resulting in a large weight of the roller brush, which will cause excessive waste of materials when replaced.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a spiral combination roller brush, comprising a roller brush assembly, both ends of the roller brush assembly are threadedly connected with a fixing tube, a carrier plate is fixed to the end of the fixing tube away from the roller brush assembly, a carrier tube is inserted in the middle of the carrier plate, and the joint of the carrier plate and the carrier tube is rotatably connected through a bearing, the roller brush assembly is used for stripping and cleaning ground impurities, a fixing block is fixed to the inner wall of the carrier tube, a spring is fixed to one side of the fixing block, a connecting tube is fixed to the other end of the spring, the connecting tube is sleeved on the outside of the carrier tube, and the carrier tube and the inner wall of the connecting tube are slidably matched, an installation groove is opened in the middle of the connecting tube, and the connecting tube is installed on the vacuum cleaner with the aid of the installation groove.

[0006] Two symmetrically arranged limiting rods are fixed to the inner wall of the connecting tube, and a limiting sliding groove for sliding of the limiting rods is provided on the outer wall of the carrier tube.

[0007] The roller brush assembly comprises a roller, the fixing tube is inserted into the interior of the roller, and the fixing tube is threadedly connected with the roller.

[0008] A partition and a plurality of bristles are fixed on the outer wall of the roller, and the partition is located in the middle of the roller.

[0009] The bristles are evenly and symmetrically arranged about the partition, and the bristles on the same side of the partition are distributed on the roller in a spiral shape.

[0010] A plurality of reinforcement rings and a plurality of reinforcement ribs are fixed to the inner wall of the roller, the plurality of reinforcement rings are arranged linearly, the plurality of reinforcement ribs are distributed in a circular array, and the plurality of reinforcement rings and the plurality of reinforcement ribs are combined into a mesh shape.

[0011] In summary, the technical effects and advantages of the utility model are:

[0023] The fixed tube 2 is fixed to the roller brush assembly by a threaded connection, so that the fixed tube 2 can be reused when the roller brush assembly is replaced, which reduces the dead weight of the roller brush assembly and avoids unnecessary waste of materials. The carrier tube 3 is rotatably connected to the carrier plate 1 through a bearing, so that when the roller brush assembly rotates, it can coordinate with the carrier plate 1 and the fixed tube 2 to rotate synchronously, thereby reducing the rotational resistance of the roller brush assembly. The compression spring 5 of the connecting tube 6 can form a folding relationship with the carrier tube 3, making it easier to install the connecting tube 6 on the vacuum cleaner with the help of the mounting groove 7.

[0024] Two symmetrically arranged limit rods 8 are fixed to the inner wall of the connecting tube 6 , and a limit sliding groove 9 for the limit rods 8 to slide is provided on the outer wall of the carrier tube 3 .

[0025] By means of the cooperation between the limiting rod 8 and the limiting slide groove 9, the carrier tube 3 and the connecting tube 6 can be prevented from being completely separated, so that the connecting tube 6 can be better connected to the vacuum cleaner through the installation groove 7 under the push of the elastic force of the spring 5.

[0026] The roller brush assembly includes a roller 10, a fixed tube 2 inserted into the interior of the roller 10, and the fixed tube 2 is threadedly connected to the roller 10, a partition 11 and a plurality of bristles 12 are fixed to the outer wall of the roller 10, the partition 11 is located in the middle of the roller 10, and the plurality of bristles 12 are evenly divided and symmetrically arranged about the partition 11, and the plurality of bristles 12 located on the same side of the partition 11 are spirally distributed on the roller 10.

[0027] A plurality of bristles 12 are designed to be evenly and symmetrically arranged about the partition 11.
