Abstract

The invention discloses a flexible and stretchable ring mouth brush suction nozzle, which belongs to the suction nozzle for a vacuum cleaner and has a vacuum cleaner structure for driving a dust loosening tool. The invention comprises an insertion pipe and a suction pipe combined with a ring brush and a duckbill sleeve at one end, and a dust suction hose sandwiched by a flexion and extension positioning mechanism is arranged between the insertion pipe and the connection pipe. The flexion and extension positioning mechanism includes the hose interface at the other end of the socket and the leaf-shaped buckles on both sides. The buckles are concentrically rotated and matched with the chuck cover and the side cover at the end of the connecting tube after being combined, and the chuck cover is equipped with a brake buckle. Elastic bayonet for middle gear. The present invention designed in this way makes the dust-absorbing hose between the insertion pipe and the connecting pipe bend to a satisfactory degree without being bent into a dead angle and not hindering ventilation. It not only maintains the original function of simply vacuuming or brushing to loosen dust, but also, because the degree of flexion and extension can be adjusted, it realizes vacuuming operations in various spaces on higher working surfaces without having to climb high.

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...
