Background technique

With the development of science and technology and the improvement of people's living standards, a variety of intelligent household cleaning appliances have appeared on the market, such as sweeping robots, which can autonomously navigate around the environment and perform cleaning operations, greatly reducing labor intensity and time.

At present, most of the sweeping robots include a roller brush assembly, a dust box and a fan, and these three components are connected in sequence. The working principle is: through the high-speed rotation of the fan, a certain vacuum is generated in the dust box, and the air is discharged from the air inlet. Inhaling air, the dust and debris near the air inlet are sucked into the dust box along with the air, and the dust box is also equipped with a filter screen and a filter element, so the air filtered by the filter screen and the filter element enters the fan, and finally exits the air outlet. is discharged, while dust and debris are left in the dust box. After the sweeping robot is finished, take out the dust box and remove the collected dust and debris.

It can be seen from the above working principle that the cleaning robot needs to ensure the airtightness of the air circulation channel composed of the roller brush assembly, the dust box and the fan when it is working. Therefore, in the existing sweeping robots, the fan and the dust box are often integrated, which not only makes the dust box unable to be cleaned with water, but also needs to be routed on the main body to supply power to the dust box, which increases the complexity of the circuit. In order to solve the above problems, some sweeper robot manufacturers set the fan assembly in the main body of the sweeping robot.
