Dust removal brush with locked-rotor indication function

Abstract

The invention discloses a dust removal brush with a locked-rotor indication function, which comprises a body and a connecting pipe, wherein a rolling brush and a driving device for driving the rollingbrush to rotate are arranged in the body; and the rolling brush comprises a roller and a central shaft. The dust removal brush with a locked-rotor indication function is characterized in that a locked-rotor indication device is arranged; the locked-rotor indication device comprises an induction coil, a magnetic ring and at least one light emitting diode electrically connected to the induction coil, the induction coil and the magnetic ring are respectively connected with one of the roller and the central shaft, and the installation positions of the induction coil and the magnetic ring are matched with each other, so that when the induction coil and the magnetic ring rotate relatively, the induction coil generates induced electromotive force. A user can visually and rapidly judge whether the rolling brush of the dust collector is in a normal working state or not, a dust removal brush does not need to be additionally arranged to be connected with a circuit of the dust collector, circuitlayout of the dust collector is not affected, and implementation is easy.

Description

technical field [0001] The invention relates to an accessory of a dust suction device, in particular to a dust removal brush used for the dust suction device, in particular to a dust removal brush which can visually indicate the occurrence of a locked-rotor state. Background technique [0002] Vacuum cleaners usually consist of a main body of the vacuum cleaner and a dust removal brush. The dust removal brush is divided into a floor brush and a bed brush, etc., and is used to clean the surface of the floor or sheets, sofas and other items. Dust removal brushes are very important for vacuum cleaners, and a good dust removal brush will substantially improve the user experience of consumers. With the development of cleaning electric vacuum cleaners, consumers have higher and higher requirements on the user interface and user experience of the vacuum cleaner, so it is necessary to improve the dust removal brush of the vacuum cleaner. [0003] In floor brushes and bed brushes, t...

Problems solved by technology

However, this solution cannot intuitively understand the rotation of the roller brush, and an alarm message can only be issued when the set value is reached. In the case of low speed and locked rotor, the difference in current change is not very obvious, and the locked rotor current of different single motors will also vary, resulting in insensitive current collection and comparison, and even judgment errors.
