Abstract

The invention discloses a retractable annular opening brush suction nozzle, belonging to suction nozzles for dust collectors. The retractable annular opening brush suction nozzle is provided with a dust collector structure for driving a dust loosening tool. The retractable annular opening brush suction nozzle comprises a socket joint tube and a suction tube, wherein one end of the suction tube is combined with an annular opening brush and a duckbill sleeve, and a dust suction hose clamped by a retractable positioning mechanism is arranged between the socket joint tube and a connection tube. The retractable positioning mechanism comprises a hose interface on one end of the socket joint tube and lobulated clamping buckles on both sides; the clamping buckles respectively form a concentric rotating fit with a chuck cover and a side cover on one end of the combined connection tube; and the chuck cover is provided with an elastic clamping pin for braking gears in the clamping buckles. According to the invention, the dust suction hose between the socket joint tube and the connection tube can be bent to the satisfactory degree without falling into a dead angle or hindering ventilation. The retractable annular opening brush suction nozzle has the original single function of dust suction or the function of loosening dust by the brush; and since the retraction degree is adjustable, the user can complete dust suction operation on high working planes and various other spaces without ascending a height.

Description

technical field [0001] The invention relates to a suction nozzle for a vacuum cleaner, or a structure of a vacuum cleaner with a tool for driving dust loosening, or a connecting tool for a hose, in particular to a flexible and stretchable ring mouth brush suction nozzle. Background technique [0002] Vacuum cleaner is a cleaning and sanitary electrical device used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. [0003] Vacuum cleaners generally include a vacuum cleaner motor that introduces current to generate suction, a motor inlet that forms an air path system, a suction head, a suction hose, a dust suction steel pipe, and a dust collection device that filters and collects inhaled objects. [0004] According to the classification of vacuum cleaners, they can be divided into vertical vacuum cleaners, horizontal (tank) vacuum cleaners and portable vacuum cleaners. [0005] In order to adapt to the dust collection work on different cleaning...
