DETAILED DESCRIPTION

[0030] The utility model will be described in further detail below with reference to the drawings.

[0031] Reference Figure 1 With Figure 2 A cleaning robot, comprising a suction assembly 100, the suction assembly 100 is arranged on the base plate 200. The second component 3 of the suction assembly 100 can be assembled on the base plate 200 by screws and the like fasteners.

[0032] The base plate 200 is assembled with a walking system, the walking system comprises wheels and steering wheels, the wheels and the steering wheels are all driven by corresponding motors, so as to drive the cleaning robot to walk, travel along the advancing direction A, realize automatic and intelligent cleaning.

[0033] Reference Figure 3 With Figure 4 The suction assembly 100 comprises a roller brush 1, a first component 2 and a second component 3, the roller brush 1 is rotatably assembled in the cavity 20 of the first component 2, and the roller brush 1 rotates along the B direction and cooperates with the advancing direction A.

[0034] The second component 3 is arranged above the first component 2, and the first component 2 and the second component 3 are connected through the floating mechanism 4, so that the first component 2 and the roller brush 1 can float in the vertical direction.

[0035] The floating mechanism 4 comprises an elastic member 41; the elastic member 41 can be a spring, an elastic rubber sleeve or the like structure.

[0036] The top of the first component 2 is provided with a guide column 25, the second component 3 is provided with a second through hole 31 matched with the guide column 25, the elastic member 41 is sleeved on the guide column 25, the lower end of the elastic member 41 abuts against the first component 2, and the upper end of the elastic member 41 abuts against the second component 3.

[0037] Therefore, the floating mechanism 4 makes the roller brush 1 press the cleaned surface downward, so as to ensure the cleaning effect. For the cleaned body such as a carpet, a bed and a sofa, the roller brush 1 can press into the cleaned body to a certain extent, so as to improve the cleaning effect. Moreover, the floating mechanism 4 also makes the roller brush 1 adapt to the uneven cleaned surface, so as to ensure the cleaning effect.

[0038] The elastic members 41 are evenly arranged, for example, four are arranged, to ensure that the roller brush 1 has sufficient downward pressure; correspondingly, the guide columns 25 and the second through holes 31 are each arranged four, and the guide columns 25 are arranged at the middle part of the first member 2. The elastic members 41 are vertically arranged to ensure sufficient floating stroke, and correspondingly, the guide columns 25 are vertically arranged.

[0039] Optionally, the second through hole 31 can be a circular hole.

[0040] Optionally, the second through hole 31 can be a long hole. The long hole is arranged along the length direction of the second member 2. When floating up and down, the first member 2 will be unbalanced, that is, the floating amount of the two ends of the first member 2 is not the same. In this case, the arrangement of the long hole structure can reduce or avoid the situation that the guide column 25 and the second through hole 31 are stuck or jammed, and promote the first member 2 to float or adjust to a certain extent in the length direction relative to the second member 3.

[0041] Reference Figure 3 , one end of the first member 2 is provided with a power mechanism 21, and the power mechanism 21 is drivingly connected with the roller brush 1;

[0044] The top of the other end of the first member 2 is provided with a groove 28, and the groove 28 is provided with the balance weight 9. The balance weight 9 can be fixed in the groove 28 by screws.

[0045] Therefore, the balance weight 9 can balance the weight of the two ends of the first member 2, that is, balance the weight of the power mechanism 21, so that the first member 2 is more stable when floating up and down, and the stress of each elastic member 41 of the floating mechanism 4 is more balanced.

[0046] Reference Figure 6 The power mechanism 21 comprises a first motor 211, a gear set 212 and an output shaft 213 which are drivingly connected in sequence. The output shaft 213 extends into the cavity 20. The gear set 212 can be placed in a gear box 214, and the gear box 214 can be assembled to the end of the first member 2 by screws or other fasteners. The output shaft 213 can be connected with the shaft hole of the roller brush 1.

[0047] Reference Figure 4 The first member 2 is also provided with a dust suction port 26. The dust suction port 26 is connected with a dust suction system which comprises a fan, a dust collecting box and other components. The dust suction port 26 can be connected with the dust suction system through a hose 7. The dust suction port 26 is arranged behind the forward direction A of the roller brush 1.

[0048] Reference Figure 4 The suction assembly 100 further comprises a strip member 6 arranged behind the advancing direction A of the roller brush 1; the strip member 6 can be assembled to the bottom of the first member 2 by means of fasteners such as screws; the strip member 6 can be in contact with the surface to be cleaned; the strip member 6 can block or gather the garbage and facilitate the garbage to be sucked into the suction port 26.

[0049] Reference Figure 5 The suction assembly 100 further comprises a plurality of auxiliary rollers 8 arranged on the periphery of the roller brush 1; for example, two auxiliary rollers 8 can be arranged behind the advancing direction A of the roller brush 1, and auxiliary rollers 8 can be arranged on the left and right sides of the advancing direction A of the roller brush 1. The auxiliary rollers 8 can be rotatably assembled on the corresponding first members 2. The auxiliary rollers 8 can be in contact with the surface to be cleaned, and can play a certain supporting role, improve the stability during walking, and ensure the relative distance between the roller brush 1 and the surface to be cleaned, thereby ensuring the cleaning effect.
