DEVICE OF CYCLONIC DIVISION Russian patent published in 2010 - IPC A47L9/16 

FIELD: personal use articles.

SUBSTANCE: device of cyclonic division is intended for a vacuum cleaner and contains the first module of cyclonic division with at least one first cyclone having an axis, placed lower on a stream concerning the first module of cyclonic division the second module of cyclonic division with the several second cyclones located with parallel functioning possibility, and the third module of cyclonic division with the several third cyclones located with parallel functioning possibility. The number of the second cyclones exceeds number of the first cyclones, and the number of the third cyclones exceeds number of the second cyclones. Every third cyclone has an axis inclined downwards in a direction to an axis of the first cyclone. The second cyclones are executed identically to each other and the third cyclones also are executed identically to each other. The device can contain the additional modules of cyclonic division located after the third module of division. One or each additional module of cyclonic division includes many additional cyclones established in parallel. The number of additional cyclones more than number of the cyclones included in the module of cyclonic division, located directly ahead of it.

EFFECT: increase of branch efficiency from a dirt and dust air stream.
