Cyclonic separation device with acceleration ramp

摘要

A cyclonic separation device for dust and debris in vacuum cleaners, comprising a roughly cylindrical interior cyclonic chamber connected to an air intake, as well as a separator filter located in the central part of the interior chamber, comprising a tube segment to direct airflow to the air intake with this tube segment located around the roughly cylindrical interior cyclonic chamber, from a starting point to an end point near the air intake, with the cross-section of this tube segment near the end point being smaller than that near the starting point in order to form an acceleration ramp for the airflow between these two points.

主权项

1. A vacuum cleaner, comprising a substantially cylindrical interior cyclonic chamber connected to an air intake, including a separator filter located in a central part of the interior cyclonic chamber, the separator filter configured to separate dust and debris from airflow, said device further comprising an intake tube having a vertical first segment fixed to the cyclonic chamber with an upper part forming an elbow followed by a horizontal second segment forming an acceleration ramp for airflow that extends around an outer surface of the interior cyclonic chamber, wherein the horizontal second segment directs airflow to the air intake and extends from a starting point to an end point near the air intake, with a cross-section of the horizontal second segment near the end point being smaller than the cross-section of the horizontal second segment near the starting point in order to form the acceleration ramp for airflow between the starting point and the end point, and wherein the vacuum cleaner comprises a handle forming a housing for the device for cyclonic separation that includes a vertical recess for receiving the vertical first segment and a horizontal recess extending from the vertical recess for receiving a first portion of the horizontal second segment such that the first portion of the horizontal second segment is positioned within the housing and a second portion of the horizontal second segment extends outside of the housing.
