(54) Dust-bag vacuum cleaner


(57) The present invention discloses a dust-bag vacuum cleaner, whose dust box (10) is provided with a dust bag (20) and an isolator (30) used for preventing the dust bag (20) from contacting walls of the dust box (10) so as to allow the airflow to pass through. The present invention, being simple in structure, can not only prevent the dust bag (20) from directly contacting sidewalls of the vacuum chamber, but also increase the air volume and keep the dust-collecting force from decreasing by fully making use of capacity inside the dust bag (20).
