Abstract
Description
Technical Field
[0001] The utility model relates to an unmanned aerial vehicle with a cleaning structure, in particular to an anti-blocking unmanned aerial vehicle with a cleaning structure. Background Art
[0002] The current cleaning technologies of cleaning robots mainly include vacuuming, sweeping, mopping, etc. Among them, some high-end cleaning robots are also equipped with special detergent spraying devices to improve the cleaning effect. In addition, some cleaning robots can also automatically identify different floor materials and stain levels, so as to select the most suitable cleaning method and strength.
[0003] The size and shape of current cleaning robots may be limited by the furniture and equipment in the home. If the size of the cleaning robot is too large, it may not be able to enter certain small spaces for cleaning. In addition, the cleaning robot may be blocked by other objects in the home and cannot reach the areas that need to be cleaned, making it difficult to clean corners, lampshades, ceilings, etc.
[0004] Manual ceiling cleaning requires the use of equipment such as ladders and even ropes to enable cleaners to reach the required cleaning height for cleaning work. When using ladders, due to the high center of gravity, cleaners can easily fall from the ladders in safety accidents. In addition, cleaners need to carry a large number of cleaning tools when climbing ladders. There is also the possibility of cleaning tools falling and injuring people at high altitudes. Drone-based cleaning devices can completely avoid such accidents and greatly reduce the probability of safety accidents. Utility Model Content

After identifying the dust, the two side brushes 2 will sweep the dust and dirt into the roller brush working area for cleaning.
