Fully-invisible folding conductive tube and dust collector comprising same

Technical Field

The invention relates to the technical field of dust collectors, in particular to a full-invisible folding conductive tube and a dust collector comprising the same.

Background

Household vacuum cleaners have been widely used in the daily life of consumers due to their excellent cleaning effect. The dust collector generally comprises a dust collection head, a conductive tube and a dust collection host which are connected in sequence, wherein the conductive tube is connected with the dust collection head and the dust collection host, and a conductive wire is arranged in the conductive tube in a penetrating manner and used for communicating the dust collection head with the dust collection host.

The current conducting tubes used in the existing dust collector are generally divided into three types, namely a straight tube, an extension tube and a folding tube, wherein the straight tube and the extension tube have relatively mature technologies and are widely applied. However, when the two pipes need to clean dust at low positions, the cleaning effect is poor, the pipe needs to be stooped down for work, and the pipe is inconvenient to use. Therefore, the folding tube is formed, the folding tube can realize the bending of the conductive tube, and the application range of the dust collector is enlarged. However, the folding part of the existing folding pipe is often complex in structure, exposed outside, thick and ugly, and not high in consumer acceptance.
