SINGLE STAGE CYCLONE VACUUM CLEANER.

摘要

The present invention relates to an upright vacuum cleaner (A) including a housing (D) and a nozzle base (C) having a main suction opening (24). The housing is pivotally mounted on the nozzle base. The housing comprises a cyclonic separator (70) including a dirty air inlet (72) and a sidewall (76). A lower end (86) of the separator being secured to a lower skirt (88). A dust collector section (100) is located beneath the separator and includes a sidewall (102). A perforated tube (140) is disposed within the separator. The perforated tube includes a shroud (152) extending away from a closed lower end of the perforated tube. A diameter of the shroud is larger than a diameter of the separator lower end. The lower skirt and the shroud define a first air channel (170) for directing air from the separator into the dust collector section. The first air channel has a substantially constant volume for maintaining airflow velocity.
