handheld vacuum cleaner

Abstract

The invention discloses a handheld dust collector. The handheld dust collector comprises a dust cup. The dust cup comprises a first cyclone device, a cyclone assembly and a filter part. The cyclone assembly comprises a plurality of second cyclone devices arranged in the circumferential direction of the first cyclone device in parallel, a guide channel is defined between every two second cyclone devices, the guide channels are communicated with a first gas outlet and guide gas flow to the periphery of the cyclone assembly along the tangent line of the circumferential wall of the adjacent second cyclone device, each second cyclone device is provided with a gas guide notch so that the gas flow can enter the second cyclone device in the tangential direction, each second cyclone device is internally provided with an air guide pipe, each air guide pipe and the inner circumferential wall of the corresponding second cyclone device are spaced, each air guide pipe is provided with an air guide inlet and an air guide outlet, and each air guide inlet is communicated with the corresponding gas guide notch; the filter part is arranged on the periphery of the cyclone assembly, and the gas flow on the periphery of the cyclone assembly enters the second cyclone devices in the tangential direction through the filter part and the gas guide notches. The handheld dust collector is good in dust and gas separating effect.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to a hand-held vacuum cleaner. Background technique [0002] In the related art, the structure for separating dust and gas in the handheld vacuum cleaner is usually easy to block the air duct. In addition, there are also some handheld vacuum cleaners that use a single-stage cyclone structure for dust and gas separation. However, this single-stage cyclone structure is relatively simple, and the effect of dust removal is not obvious, which makes the filter located downstream of the single-stage cyclone structure easy to block. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a hand-held vacuum cleaner, the separation effect of the dust cup of the hand-held vacuum cleaner is good. [0004] The handheld vacuum cleaner according t...
