Dust collection brush head of dust collector

Abstract

The invention discloses a dust collection brush head of a dust collector. The dust collection brush head comprises a brush head main body shell and a rotating shaft, wherein the rotating shaft is directly driven to rotate by virtue of a direct drive motor which is arranged in the brush head main body shell; and a plurality of rotary brushes, which are rotated along with the rotating shaft, and a movable brush, which can do reciprocating moving in an axial direction of the rotating shaft under the rotating driving of the rotating shaft, are arranged on the rotating shaft. When the dust collector provided by the invention is used for collecting dust, the movable brush is driven to do reciprocating moving by virtue of a guide rotary groove when brush bristles, driven by the rotating shaft, are rotated to remove dirt and collect dust so as to scrub and collect dirt in a transverse direction; therefore, a dust collection effect is enhanced; moreover, with the adoption of the direct drive motor, the volume of the brush head is greatly diminished and the convenience of the dust collector is enhanced, so that the dust collector can collect dust at various corners conveniently; and the dust collector provided by the invention is original in structure, convenient and reliable to use and quite strong in practicability.

Description

technical field [0001] The invention relates to a dust-absorbing brush head of a vacuum cleaner, which belongs to the technical field of vacuum cleaners. Background technique [0002] At present, vacuum cleaners have been widely used. Vacuum cleaners are mainly composed of three parts: dust collection, dust collection, and dust filtration, generally including series commutator motors, centrifugal fans, dust filters (bags) and dust collection accessories. Generally, the power of the vacuum cleaner is 400-1000W or higher, and the power of the portable vacuum cleaner is generally 250W or less. The vacuum cleaner can remove dust, mainly relying on the electric exhaust fan. There is a wind impeller on the shaft of the exhaust fan. After power on, the exhaust fan will generate strong suction and pressure at a speed of 500 cycles per second. The air in the fan is replenished in a timely manner, resulting in an instantaneous vacuum inside the vacuum cleaner, forming a negative pres...

AI Technical Summary

Problems solved by technology

Its quality is directly related to the dust-absorbing effect of the vacuum cleaner. However, the current dust-absorbing brush head is generally realized by simple bristles or floor brushes. The dirt on the items is difficult to effectively remove the dirt only by the suction of negative pressure, which seriously affects the effect and efficiency of vacuuming. It is not suitable for vacuuming in such dirty places, and it is impossible to truly achieve dust removal and cleaning. Vacuum effect
