Abstract

The invention discloses a retractable pointed-end suction nozzle, belonging to suction nozzles for dust collectors. The pointed-end suction nozzle comprises a socket joint part on one end and a suction nozzle part on the other end. The invention is characterized in that the socket joint part of the pointed-end suction nozzle is fixed with a clamping buckle interface on one end of a retractable positioning mechanism; a dust suction hose is communicated with the clamping buckle interface on one end of the retractable positioning mechanism and a connecting tube on the other end; the retractable positioning mechanism comprises a clamping buckle provided with a buckling interface and a chuck, and forms a concentric rotating fit with a chuck cover and a side cover on the combined connecting tube; and the chuck cover is provided with an elastic clamping pin for braking the clamping buckle. According to the invention, the pointed-end suction nozzle and the retractable positioning mechanism are integrated; the retraction angle is selected according to the requirements of the working plane and the will of the user; and the invention has the function of cleaning high-position regions, corner working planes and various other spaces, thereby adding a new integrated component for the suction nozzle of the dust collector by combining the pointed-end suction nozzle with the retractable positioning mechanism.

Description

technical field [0001] The invention relates to a suction nozzle for a vacuum cleaner, in particular to a flexible and stretchable pointed 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 surfaces, the suction head (or brush head) of the vacuum cleaner can have different structures and uses, such as tap...
