A dust collection container for power tool with suction capacity is described comprising a first pipe (15) for air inlet and at least one second pipe (20) for air outlet, i.e. connected to the external environment, the dust container (13) comprising a filtering element (22) placed inside an external casing (14). The container further comprising a bladed element (100) accommodated in the external casing (14) and being adapted to increase the air turbulence. The shape of the space comprised between the filtering element (22) and the external casing (14) determines a cyclonic type air motion.

The invention claimed is: 1. A dust collection container for power tool with suction capacity, comprising a first pipe for air inlet into a head chamber, and at least one second pipe for air outlet connected to the outside environment, said dust container comprising a filtering element placed inside an external casing, and a bladed element accommodated in said external casing, said filtering element delimiting an internal space communicating with said second pipe and an external space communicating with said head chamber through the bladed element surrounding said internal space, characterized in that: said bladed element is provided with a cylindrical portion containing the head of the filtering element and outwardly supporting a plurality of peripheral blades radially extending from the external surface of the filtering element to the internal surface of the external casing at the inlet of said external space. 2. The container according to claim 1, characterized in that said peripheral blades have diverting surfaces inclined with respect to the filtering element and the external casing. 3. The container according to claim 1, characterized in that said bladed element comprises an air conveying conical head portion mounted on the head of the filtering element. 4. The container according to claim 1, characterized in that the container comprises a head chamber upstream of the bladed element. 5. The container according to claim 1, characterized in that said external casing comprises a removable dust accumulation closing element. 6. The container according to claim 1, characterized in that said filtering element is truncated-cone-shaped. 7. The container according to claim 1, characterized in that said filtering element is cylindrical-shaped. 8. The container according to claim 1, characterized in that said external casing is cylindrical-shaped. 9. The container according to claim 1, characterized in that said external casing has at least one truncated-cone-shaped portion. 10. The container according to claim 1, characterized in that the external surface of filtering element is inclined with respect to the internal surface of the external casing, said conformation causing a cyclonic motion of the air after the same has interacted with the bladed element. 11. The container according to claim 1, characterized in that said filtering element is removably couplable with the bladed element. 12. The container according to claim 1, characterized in that said bladed element is removably couplable with the external casing. 13. The container according to claim 1, characterized in that said bladed element is integrally made with the external casing. 14. The container according to claim 1, characterized in that said bladed element is integrally made with the filtering element.
