Detailed Description

The utility model is described in further detail below with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 3, a vacuum cleaner with an improved air duct comprises a vacuum cleaner main body 1, which comprises a main body seat 10 and a suction pipe 11 connected with the main body seat 10 and used for dust collection, wherein a fitting head is inserted at the end of the suction pipe, the main body seat 10 comprises a negative pressure chamber 2 and a storage box 3, the bottom cover of the storage box 3 can be opened and closed, and the storage box 3 and the vacuum cleaner main body 1 are detachably and fixedly connected; the negative pressure chamber 2 and the storage box 3 are communicated through a filter screen mechanism 4, the suction pipe 11 is communicated with the storage box 3, the storage box 3 is divided into a first storage part 31 and a second storage part 32 through a baffle 5 arranged at the middle position, the baffle 5 comprises a baffle seat 52 arranged at the middle position and a first guide plate 51 arranged at the periphery of the baffle seat 52 and provided with a turning track, a through hole 50 is formed in the first guide plate 51, and the first guide plate 51 is positioned at the height of one side of the through hole 50 and higher than the height of the other side of the through hole 50.

In the above structure, the storage box 3 is separated into the first storage part 31 located above and the second storage part 32 located below by the baffle 5, and the first guide plate 51 arranged on the periphery of the baffle separates the garbage absorbed from the suction pipe 11 in a spiral direction, so that large-particle garbage is conveyed to the lower part of the storage box (i.e. the second storage part 32), and small particles such as dust are stored in the upper part of the storage box, which makes the problem of dust exposure not caused when the box cover located at the part below the storage box is opened.

Further, the filter screen mechanism 4 comprises a filter screen cylinder 40 and a filter screen seat 41 arranged at the upper end of the filter screen cylinder 40, the bottom of the filter screen cylinder 40 is matched with the baffle seat 52 in shape, and the filter screen cylinder abuts against the baffle seat 52. The lower end surface of the filter screen seat 41 is provided with a second guide plate 42 with a spiral track. The partial garbage absorbed to the second diversion plate 42 by the negative pressure can be separated along the second diversion plate 42 in the rotating direction, so as to further improve the separation effect.
