When in operation, the air-supply pipe stretching means retracts and stretches the air-supply pipe, which enables the guiding air hammer to clean out the dust on the inner walls and in the corners of a ventilation duct without the need of an operator entering the ventilation duct. The air-supply pipe stretching means may be controlled by manual operation or program composition. The device may be used for cleaning ventilation ducts with a polygonal section.Type: GrantFiled: February 28, 2005Date of Patent: April 14, 2009Inventor: Jiang Yu

Publication number: 20090083934Abstract: A sweeping broom apparatus for use with a vehicle comprises a main body with a debris receiving inlet, and a broom shroud with an open bottom. Airflow obstructing flaps are disposed around the bottom edge of the broom shroud. A forwardly facing debris outlet in the broom shroud permits the directed egress of debris therefrom as a forwardly propelled stream of debris. A main sweeping broom is mounted within the broom shroud for propelling debris forwardly, thereby creating a stream of debris propelled forwardly through the forwardly facing debris outlet. An air blast nozzle is connected in fluid communication to a source of compressed air for receiving compressed air therefrom. There is a nozzle mount for mounting the air blast nozzle for movement between a lower position whereat the air blast nozzle is disposed adjacent the surface being cleaned and to emit air in a forward and downward direction to impact on the surface being cleaned, and a raised impact-absorbing position.Type: ApplicationFiled: September 25, 2008Publication date: April 2, 2009Inventor: Roger P.
