Dust collector of vacuum cleaner

Abstract

The present invention relates to dust collector of vacuum cleaner, and aims at avoid foreign matter splash and raising dust collecting performance. The dust collector includes one first cylindrical cyclone unit with opened lower end and to separate foreign matters from the inflow air on the cyclone principle; one second dust separating unit around the first cyclone unit to further separate foreign matters from the air the first cyclone unit exhausts; one dust storing unit including one first dust storing part to store the foreign matters the first cyclone unit separates out and one second dust storing part to store the second dust separating unit separates out; one splash preventing unit to avoid the elevation of dust in the first dust storing part caused by the eddy flow; and one partitioning wall to separate the first dust storing part and the second dust storing part.

Description

technical field

[0001] The invention relates to a dust collecting device of a vacuum cleaner, in particular to a dust collecting device of a vacuum cleaner which utilizes the principle of a cyclone to collect dust and foreign matter. Background technique

[0002] The cyclone dust collection device is a device that uses the principle of the cyclone to collect dust and other foreign substances in the air. The cyclone dust collection device is suitable for many fields, and it is mainly suitable for vacuum cleaners in the home.

[0003] In recent years, in order to improve dust collection performance, a multi-cyclone dust collector having a plurality of cyclones is used.

[0004] Combine below figure 1 A dust collecting device of a conventional vacuum cleaner will be described.

[0005] The existing dust collection device includes the following parts: a primary cyclone dust collection part 10 that inhales polluted air from the outside and collects relatively large dust; a sec...
