Movably sleeved spike-like suction nozzle of dust collector

Abstract

The invention discloses a movably sleeved spike-like suction nozzle of a dust collector, which comprises a suction nozzle body and a connecting pipe, wherein a suction inlet is formed on the suction nozzle body, and the suction nozzle body is connected to a telescopic pipe of the dust collector by the connecting pipe. Besides, the connecting pipe is formed on the suction nozzle body integrally and communicated with the suction inlet, and a brush is arranged at one end of the suction inlet on the suction nozzle body. The suction inlet comprises an inner annular suction inlet and an outer annular suction inlet, the suction nozzle body consists of two nested sleeves, the inner annular suction inlet is formed by the hollow space of the inner sleeve, and the outer circular suction inlet is formed by the annular space between the inner sleeve and the outer sleeve. The brush is arranged on the outer end face of the inner sleeve, and an elastic connection structure is arranged in the annular space between the inner sleeve and the outer sleeve. A certain space is reserved between the insert end of the inner sleeve and the end of the outer sleeve on the same side, and airflows which contain different dirt and are sucked from the inner annular suction inlet and the outer annular suction inlet are converged in the space, and finally are sucked into a dust collection barrel of the dust collector through the connecting pipe. The movably sleeved spike-like suction nozzle of the dust collector can be used for cleaning dirt gaps thoroughly, and accordingly dust collection efficiency can be improved.

Description

technical field [0001] The invention relates to a suction nozzle structure for a vacuum cleaner, in particular to a nested movable pointed suction nozzle of a vacuum cleaner. Background technique [0002] When cleaning indoors, cars and other places, ordinary brooms or other cleaning tools have places that are difficult to clean. Usually, vacuum cleaners are used to clean the places that are difficult to clean, and use suction to suck in dust and other dirt. Such as figure 1 As shown, the vacuum cleaner is generally composed of a vacuum cleaner body 10 and a suction nozzle 20, and the vacuum cleaner body 10 has a motor, a fan and a dust collection bag (bucket). The motor and fan are used to generate suction, and all kinds of dirt sucked under the action of suction are collected by the dust bag (barrel). Usually, a suction pipe 31 , a handle 32 and a telescopic pipe 33 are sequentially connected between the main body 10 of the vacuum cleaner and the suction nozzle 20 . Aft...

Problems solved by technology

In addition, since the brushes 103 at the front end of the nozzle part 1 are fixed relative to the nozzle part 1, it is difficult to control the direction of these fixed brushes 103 by using the handle of the vacuum cleaner. Therefore, the dust or lint in the gap cannot be completely cleaned. , confetti, etc.

To sum up, using the vacuum cleaner with the above-mentioned sharp nozzle structure, there will often still be dirt left in the suctioned gap, the cleaning effect is not ideal, and the dust collection efficiency is low
