Embodiment Construction

[0038] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0039] As shown in Fig. 4 and Fig. 5, the multi-cyclone dust collection device of the present invention includes a dust suction container 5 for dust collection by separating impurities; a plurality of secondary cyclones 3 installed on the outer peripheral side of the dust collection container; The space portion 23 formed on the side of the second inlet 33 of each secondary cyclone 3 ; and the molding portion 100 formed in each space portion 23 .

[0040] The central portion of the dust collection container 5 also includes a cylindrical primary cyclone device 1 that uses the principle of a cyclone to separate impurities contained in the air flowing into it. The secondary cyclone 3 is smaller than the primary cyclone 1 and There are a plurality of them, and they are installed sequentially along the outer circumference of the primary cyclone 1 . I...

Abstract

A multiple cyclones type dust sucking mechanism for vacuum cleaner is composed of a dust sucking container for separating impurities and sucking dust, multiple secondary cyclone units surrounding part of the circumference of said dust-sucking container, multiple space parts for said secondary cyclone units (one for one), and multiple shaping parts for said space parts (one for one) in order to prevent the collection of dust in space part.

Description

technical field [0001] The invention relates to a dust collection device for vacuum cleaning equipment, in particular to a multi-cyclone dust collection device which utilizes the cyclone principle to collect dust for impurities. Background technique [0002] The multi-cyclone dust collection device refers to the device that uses the principle of cyclone to separate the contained dust and other impurities from the air. The multi-cyclone dust collection device is suitable for various fields, and the household is mainly used for vacuum cleaning equipment. [0003] Recently, in order to improve dust collection performance, a multi-cyclone cleaner having a plurality of cyclones is used. [0004] As shown in Figure 1, the multi-cyclone type dust suction device of existing vacuum cleaning equipment includes the cyclone 1 (hereinafter referred to as the primary cyclone) that sucks polluted air from the outside and carries out dust suction to larger dust; The secondary cyclone 1 is...
