Electric vacuum cleaner

Abstract

The invention relates to an electric dust collector, aiming at providing a small-sized electric dust collector with an easily operated cyclone separating dust collecting part. In the invention, a cyclone separating tube (104) for centrifugal separating and dust collecting and a dust collecting box (105) provided with a first auxiliary filter (106) inside are independently detachably arranged in parallel on a lower shell (101) of a dust collector body (1); part of the gas exhausted by the cyclone separating tube (104) flows into an electric blower through the dust collecting box (105). Furthermore, in the invention, the cyclone separating tube (104) for centrifugal separating and dust collecting and the dust collecting box (105) provided with the first auxiliary filter (106) inside are independently detachably arranged in parallel on the lower shell (101) of the dust collector body (1); part of the gas exhausted by the cyclone separating tube (104) flows into the electric blower through the dust collecting box (105) and a filter arranged below.

Description

[0001] This application is a divisional application. The application date of the original application is June 4, 2003, the application number is 03141284.X, and the invention name is electric vacuum cleaner. technical field [0002] The present invention relates to electric vacuum cleaners. Background technique [0003] A general electric vacuum cleaner is a structure in which the dusty air inhaled from the suction port is introduced into the vacuum cleaner body, the dust is removed by the dust collecting part in the vacuum cleaner body, and the clean air after dust removal is discharged outside the vacuum cleaner body. The dust collection part is a structure that captures dust through the filtration of a paper filter, or captures dust through centrifugal separation of a cyclone separator. [0004] An electric vacuum cleaner having a cyclone-type dust collecting unit is described in JP-A-2001-29288. The dust collection part of this electric vacuum cleaner is a structure whi...

Problems solved by technology

[0007] The dust collection unit that captures dust with one cyclone separator collects coarse dust and fine dust together, so when discarding the captured dust, the fine dust is easy to scatter, and the dust disposal operation is troublesome

In addition, if the performance of dust capture (dust collection = dust removal) is to be improved, the cyclone separator will inevitably become longer, leading to an increase in size.

[0008] Cyclone dust separator (dust collection unit) with inner and outer double separation cylinder structure is difficult to be compact and easy to operate due to the integrated structure of the outer separation cylinder and the inner separation cylinder

For general household use, although a large amount of coarse dust is captured and the operation frequency of discarding the coarse dust is high, the dust collection part with the structure of the inner and outer double separation cylinders cannot achieve the outer separation of only taking out and capturing the coarse dust cylinder, only the coarse dust is discarded
