As shown in fig. 1 to 3, the present embodiment provides a roll brush, including:

the rotary drum comprises a rotary drum 1, wherein a plurality of mounting grooves 11 communicated with an inner cavity of the rotary drum 1 are formed in the circumferential direction of the rotary drum 1;

the telescopic positioning assembly 2 is assembled in the inner cavity, and the telescopic positioning assembly 2 can move along the axial direction of the roller 1 and is positioned at two ends of the moving track of the roller;

the bristle assemblies 3 are arranged in the mounting groove 11, the telescopic positioning assembly 2 is in driving connection with the bristle assemblies 3 through a connecting rod 5 and is used for driving the bristle assemblies 3 to stretch and retract along the radial direction of the roller 1;

a fluff assembly 4, said fluff being assembled on the surface of said cylinder 1.

Therefore, two brush structures of a bristle component 3 and a soft bristle component 4 are integrated on the rolling brush, wherein the bristle component 3 is made of hard materials, the hard bristle component 3 can be used for cleaning a carpet, the soft bristle component 4 is made of soft materials, and the soft bristle component 4 is made of soft materials and can be used for cleaning the floor. And the two brush structures of the bristle component 3 and the soft bristle component 4 can be oppositely switched on the rolling brush, wherein the soft bristle component 4 is a fixed structure fixed on the surface of the roller 1, the bristle component 3 is movably assembled in the mounting groove 11 corresponding to the soft bristle component 4, so that the bristle component 3 can adjust the radial position relative to the soft bristle component 4 by extending or retracting in the mounting groove 11.

Wherein the control of the extension or retraction of the bristle assembly 3 can be achieved using the telescopic positioning assembly 2. The telescopic positioning component 2 is assembled in the inner cavity, and the telescopic positioning component 2 can move along the axial direction of the roller 1 and can be positioned at two ends of the moving track, for example, when the telescopic positioning component 2 moves linearly in the inner cavity of the roller 1 along the axial direction of the roller 1, the telescopic positioning component 2 can be positioned at the current first positioning position when the telescopic positioning component 2 moves to one end of the moving track along the moving track of the linear movement of the telescopic positioning component 2. Similarly, when the telescopic positioning assembly 2 moves linearly in the inner cavity of the roller 1 along the axial direction of the roller 1, the telescopic positioning assembly 2 moves to the other end of the moving track along the moving track of the linear movement of the telescopic positioning assembly 2, and at this time, the telescopic positioning assembly 2 can be positioned at the current second positioning position.

Therefore, when the telescopic positioning component 2 moves axially in the inner cavity of the roller 1, the connecting rod 5 can be driven to rotate, and the connecting rod 5 can drive the bristle component 3 to extend or retract in the mounting groove 11 along with the movement of the telescopic positioning component 2 because two ends of the connecting rod 5 are respectively hinged with the bristle component 3 and the telescopic positioning component 2, namely, the telescopic positioning component 2 can be in driving connection with the bristle component 3 through the connecting rod 5, and then the bristle component 3 is driven to extend and retract along the radial direction of the roller 1.

Since the retractable positioning assembly 2 can be positioned at the first and second positioning positions when it is moved linearly in the axial direction in the inner cavity of the roller 1, the retractable positioning assembly 2 can be moved to the first and second positioning positions to fix the bristle assembly 3 in the extended state or the retracted state, which are the carpet cleaning mode and the floor cleaning mode of the roller brush.

When the bristle assembly 3 extends out of the mounting groove 11, the bristle assembly 3 should be higher on the surface of the roller brush than the soft bristle assembly 4, while the bristle assembly 3 is in an active state in which the roller brush belongs to the cleaning mode of a carpet scene. When the bristle assembly 3 is retracted into the mounting groove 11, the bristle assembly 3 should be lower at the surface of the roller brush than the bristle assembly 4, while the bristle assembly 4 is in an active state in which the roller brush belongs to the cleaning mode of the floor scene.

Therefore, when the cleaning environment is a floor, the bristle sub-assembly 3 is in a retracted state, and the roll brush is switched to a floor cleaning mode in which the bristle sub-assembly 4 is in contact with the floor and cleans the floor, and at this time, the bristle sub-assembly 3 is not in contact with the floor, thereby protecting a hard floor such as the floor from being damaged. When the cleaning environment is a carpet, the bristle component 3 is in an extending state, the roller brush is switched to a carpet cleaning mode, the bristle component 3 is in contact with the carpet and cleans the floor in the carpet cleaning mode, and the soft bristle component 4 is not in contact with the carpet at the moment, so that the cleaning efficiency is improved.

Therefore, through the extension or retraction position of the bristle component 3 in the mounting groove 11, the bristle component 3 and the soft bristle component 4 protrude out of the surface of the rolling brush relative to each other, so that the switching of cleaning modes of different scenes of the rolling brush can be completed, a user does not need to manually replace different types of brushes, and only the extension or retraction of the bristle component 3 in the mounting groove 11 needs to be controlled through the telescopic positioning component 2, so that the use is very convenient.
