Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a floor brush head structure. Background Art

[0002] In the related art, most handheld cleaning devices have the sewage tank installed on the main unit. During actual use, when encountering dead corners such as under sofas and beds, the main unit needs to be tilted to a flat position before the floor brush head can be inserted for cleaning. During this process, the sewage in the sewage tank can easily flow back into the vacuum motor due to surges, thereby affecting the service life of the vacuum motor. In addition, in the related art, the vacuum motor, sewage tank, and battery are all installed in the main unit of the handheld cleaning device, which means that the pressure applied by the floor brush head to the roller brush is relatively small, and the friction between the roller brush and the cleaning surface is small, resulting in poor cleaning effect.
