Handheld dust collector

Abstract

The embodiment of the invention relates to a dust collector and discloses a handheld dust collector which includes a casing, a filter screen and a cyclone separator, wherein the casing is used for being detachably connected with a dust collecting cup of the dust collector; the filter screen is arranged in the dust collecting cup in a surrounding mode and used for filtering out dust; the cyclone separator is disposed in the dust collecting cup and used for being surrounded by the filter screen; the casing is internally also provided with an accommodating chamber for placing a filter cartridge,and the accommodating chamber is located above the cyclone separator after the casing is detachably connected with the dust collecting cup. Compared with the prior art, the filter cartridge of the dust collector is convenient to dismantle and easier to clean, the dust filtering intensity of the dust collector is maintained, and the size of the dust collector is reduced.

Description

technical field [0001] Embodiments of the present invention relate to a vacuum cleaner, in particular to a handheld vacuum cleaner. Background technique [0002] The handheld vacuum cleaner is small in size, very convenient to carry and use, and suitable for use in a small space. Hand-held vacuum cleaners generally include a shell, fan, filter, dust collection tube, cyclone separator, filter element and suction nozzle. The fan sucks air, and the airflow carrying dust enters the dust collection cylinder through the suction nozzle, and then filters through the filter device. Most of the dust stays in the dust collection tube, and the airflow passes through the filter to form a cyclone by the cyclone separator, and the airflow after the cyclone is filtered again by the filter element, and finally discharged into the atmosphere by the fan. [0003] However, the inventor found that the cyclone separator of the existing hand-held vacuum cleaner is arranged above the filter screen...

AI Technical Summary

Problems solved by technology

[0003] However, the inventor found that the cyclone separator of the existing hand-held vacuum cleaner is arranged above the filter screen and placed in the housing, and the filter element is placed in the cyclone separator. Due to space constraints, only small filter cotton can be used to filter. After the vacuum cleaner has been used for a long time Residual dust blocks the filter element and affects the filtering effect of the filter element, so the filter element needs to be cleaned or replaced

However, since the filter element is set in the cyclone separator, it is troublesome to disassemble and difficult to clean

At the same time, the cyclone separator is located above the filter net, which makes the overall space of the vacuum cleaner larger, the customer experience is poor, and the arrangement of other components in the vacuum cleaner is not regular
