[0040] The cleaning roller brush of the embodiment is capable of driving the movable blade 4 to reciprocate relative to the fixed blade 5 along the axis direction of the roller brush body 1 when the roller brush body 1 is driven to rotate in the first rotation direction, so as to cut the filaments such as hairs wound on the roller brush body 1. In the design, the movable blade 4 is driven to move relative to the fixed blade 5 by the power driving the roller brush body 1 to rotate, so that a separate driving member for the movable blade 4 is not needed, the problem of too crowded internal space of the cleaning roller brush leading to difficult layout of components is effectively solved, and the use energy consumption and production cost of the cleaning device can be reduced.

[0041] Further, as shown in Figure 2 the transmission assembly of the embodiment specifically comprises a rotating shaft 3 located in the accommodating cavity and rotationally connected with the accommodating cavity, and the rotating shaft 3 is provided with a driving cam 6;

[0042] The part of the movable blade 4 located in the accommodating cavity is connected with a protruding portion 401 matched with the driving cam 6;

[0043] When the roller brush body 1 is driven to rotate in the first rotation direction, the rotating shaft 3 rotates relative to the accommodating cavity, and the driving cam 6 is matched with the protruding portion 401 to drive the movable blade 4 to reciprocate relative to the fixed blade 5 along the axis direction of the roller brush body 1.

[0044] Specifically, the rotating shaft 3 of the embodiment is inserted into the accommodating cavity from one end of the roller brush body 1 and can rotate relative to the accommodating cavity.

[0045] In addition, in order to make the rotating shaft 3 rotate more smoothly, a bearing 10 is installed at the end of the roller brush body 1, and the shaft body of the rotating shaft 3 is connected to the bearing 10.

[0046] Further, as shown in Figure 2 and Figure 3 the end face of the driving cam 6 of the embodiment towards the protruding portion 401 is an inclined face, wherein the inclined face is provided with a cam groove 601 matched with the protruding portion 401;

[0065] It should be noted that through the above design, when the movable blade 4 reciprocates in the first direction and the second direction, the guide protrusion 1101 moves in the guide groove 402, thereby effectively improving the stability of the movable blade 4 during movement.

[0066] Further, the opposite sides of the movable blade 4 and the opposite sides of the fixed blade 5 are both provided with the cutting part.

[0067] The number of the grooves 2 in the embodiment is two, and the two grooves 2 are symmetrically arranged about the central axis of the roller brush body 1.

[0068] Specifically, the cutting part in the embodiment is a comb-shaped sawtooth.

[0069] It should be noted that through the above design, the opposite sides of the cleaning roller brush can both have the function of cutting hair, effectively improving the anti-winding efficiency, and the internal center of gravity of the cleaning roller brush is more stable, and the dynamic balance is more stable, thereby effectively preventing the cleaning roller brush from shaking during cleaning.

[0070] Please refer to Figures 1 to 4 The cleaning device in the embodiment is specifically a dust collector, a cleaning robot, etc., which specifically includes the cleaning roller brush and a driving member for providing driving force for the cleaning roller brush to rotate to perform cleaning work.
