[0027] See also Figure 1-Figure 6 The utility model provides a sweeping robot structure, including a dust suction pipe 1, a bristle structure 2, a dust collecting chamber 3 and a suction fan 4;

[0028] The dust suction pipe 1 is provided with a front pipe 11 and a rear pipe 12, and the front pipe 11 and the rear pipe 12 form a zigzag, and are connected to the dust collecting chamber 3 from the bottom of the sweeping robot. The dust inlet 13 of the front pipe 11 is provided at the front end of the brush structure 2 in the forward direction of the sweeping robot. The dust inlet 13 of the dust suction pipe 1 is provided at the bottom of the sweeping robot and is close to the ground when the sweeping robot is working. The rear pipe 12 is communicated with the front pipe 11 and is connected to the dust collecting chamber 3. The bristle structure 2 is provided with at least two openings, and the first opening 21 faces the ground. When the sweeping robot is working and moving, hair enters from the first opening 21, and the second opening 22 is connected to the dust collecting chamber 3.

A suction channel 5 is provided between the suction fan 4 and the dust collecting chamber 3, and the wind force of the suction fan 4 acts on the dust suction pipe 1 through the suction channel 5.

[0029] Specifically, the front tube 11 is a straight tube perpendicular to the ground, and the inner diameter of the front tube 11 is 1-3 cm. If the inner space is too large, the suction fan 4 will have insufficient wind force, making it difficult to suck hair and other debris into the dust collecting chamber 3. If the inner space is too small, the inner cavity will be blocked, making it difficult to clean when hair accumulates. Both ends of the rear tube 12 are slightly bent downward, and the lower end of the connection between the rear tube 12 and the dust collecting chamber 3 is the second opening 22 of the bristle structure 2.

[0030] For details, please refer to Figure 6 The bristle structure 2 is provided with a partition 7 at the second outlet. One end of the partition 7 is fixed, and the other end can swing toward the dust collecting chamber 3. The second opening 22 is a downwardly inclined expansion, providing space for the partition 7 to swing. The top of the partition 7 is fixed to the second opening 22, and the partition 7 can swing upward through the negative pressure formed by the rotation of the bristle structure 2. When the bristle structure 2 stops working, the partition 7 closes the second opening 22. The negative pressure generated by the bristle structure 2 is limited. The partition 7 has a certain weight. The negative pressure can swing the partition 7 to be parallel to the ground. When the partition 7 is parallel to the ground, there is still space for the hair debris to flow through at the connection between the dust suction tube 1 and the dust collecting chamber 3.

[0031] Specifically, the bristle structure 2 includes a rotating shaft and bristles. The bristles rotate around the rotating shaft. When the sweeping robot is working, the bristles can contact the ground during rotation, separate the dust adsorbed on the ground, and transfer it to the dust collecting chamber 3. The rotating shaft is connected to the motor, and the motor provides the energy required for the sweeping robot to work.
