Dust separation apparatus
DCFirst Claim
1. Vacuum cleaner apparatus for separating dirt or dust from an airflow comprising a frustoconical cyclone having a tangential air inlet located at or adjacent the end of the cyclone having the larger diameter and a cone opening located at the end of the cyclone having a smaller diameter than at the end having the larger diameter, and a collector arranged so as to surround the cone opening and having a base surface facing towards the cone opening, wherein the distance between the cone opening and the base surface is either less than 8 mm or between 30 mm and 70 mm such that there is improved separation of the dirt or dust because of the distance in the apparatus.

Abstract
An apparatus (10) for separating dirt or dust from an airflow comprising a frustoconical cyclone (12) having a tangential air inlet (16) located at or adjacent the end of the cyclone (12) having the larger diameter and a cone opening (18) located at the end of the cyclone (12) having the smaller diameter is described. A collector (20) is arranged so as to surround the cone opening (18) and has a base surface (24) facing towards the cone opening (18). The distance between the cone opening (18) and the base surface (24) is between 4 and 6 mm or between 45 and 60 mm. The apparatus (10) is reduced in size without substantially affecting the separation efficiency.
