Description

Cleaning assembly and sweeping robot Technical Field The application relates to a cleaning assembly and a sweeping robot, and belongs to the technical field of cleaning equipment. Background When the floor sweeping robot cleans the floor, the floor sweeping robot is mainly contacted with the floor through the rotation of the rolling brush, and dirt is collected into the floor sweeping robot by matching with the suction force of the floor sweeping robot. Accordingly, the suction force of the sweeping robot determines the effect of the sweeping robot on collecting dirt. Because the position that the round brush set up can shelter from the inside air inlet of robot that sweeps floor to a certain extent, consequently, can lead to sweeping robot's suction difficult further promotion to lead to sweeping robot's cleaning effect relatively poor. Disclosure of utility model The application provides a cleaning assembly and a sweeping robot, which are used for solving the problem that the suction force of the sweeping robot is not enough in the related art. In order to achieve the above purpose, the present application adopts the following technical scheme: In a first aspect, the present application provides a cleaning assembly comprising: The shell is provided with an air inlet, a mounting cavity and a dust collecting port, and the mounting cavity is communicated with the air inlet and the dust collecting port; The two rolling brushes are at least partially arranged in the installation cavity, are rotatably connected with the shell, are intersected or collinear in central axes, and are arranged opposite to the dust collecting opening; The outer diameter of the part of the rolling brush adjacent to the air inlet is smaller than that of the part of the rolling brush far away from the air inlet; and the driving piece is connected with the rolling brush and is configured to drive the rolling brush to rotate. In the cleaning assembly provided by the application, the rolling brush can be contacted with the ground, and the driving piece can drive the rolling brush to rotate, so that the rolling brush can roll garbage on the ground into the mounting cavity. The air inlet of the shell can be connected with the dust box, and negative pressure is formed in the dust box, so that garbage in the installation cavity and on the surface of the rolling brush can be sucked into the dust box through the air inlet. By making the outer diameter of the portion of the rolling brush adjacent to the air inlet smaller than the outer diameter of the portion of the rolling brush remote from the air inlet, the portion of the outer diameter of the rolling brush can be made relatively small and the portion of the outer diameter relatively large. The external diameter of the part of the rolling brush adjacent to the air inlet is smaller, so that the space of the rolling brush adjacent to the air inlet in the installation cavity is smaller, the shielding of the rolling brush to the air inlet can be reduced, the suction force at the air inlet is larger, and the cleaning assembly can suck garbage more fully. The outer diameter of the part of the rolling brush far away from the air inlet is relatively larger, so that the rolling brush can keep a relatively larger surface area, the cleaning effect of the rolling brush on ground garbage is better, and finally, the cleaning effect of the cleaning assembly is better. In some embodiments, the roller brush has a first side and a second side in an axial direction of the roller brush, a direction from the first side to the second side being a direction in which the roller brush is away from the air inlet, and an outer diameter of the roller brush gradually increases in the direction from the first side to the second side. Therefore, the rolling brush can be in a round table or conical structure, so that the structure of the rolling brush is more regular, and the processing is more convenient. In some embodiments, the central axes of the two rolling brushes are arranged in an intersecting manner. In some embodiments, the half apex angle of the cone where the rolling brush is located is a first angle, the included angle between the axial direction of the rolling brush and the plane where the dust collecting port is located is a second angle, and the first angle is equal to the second angle, so that in the direction from the first side to the second side, the outer wall of one side of the rolling brush facing the dust collecting port is consistent with the distance between the dust collecting port. Through making the round brush towards the interval unanimity of air inlet one side, can make the round brush follow the circumference outer wall of first side to the second side all can be with ground contact, increased the area of contact of round brush and ground, improved clean effect. In some embodiments, the first angle is greater than 0 °, and not greater than 8 °. In some embodiments, the first angle is 4 °. Thr
