Abstract
A suction nozzle for use with an extraction cleaner having a suction source includes a tool body and a front cover connected to the tool body. The tool body includes a rear wall. The tool body defines an exhaust port configured to connect to the suction source. The front cover and the rear wall together define an extraction nozzle volume having a suction inlet. The tool body defines a pair of air vents situated above the suction inlet. The front cover has a pair of side walls. In some embodiments, lateral edges of the side walls adjacent to the suction inlet define an arcuate notch for introducing a slipstream into the extraction nozzle volume.
Claims18
A suction nozzle for use with an extraction cleaner having a suction source, comprising:
- a tool body having a rear wall, wherein the tool body defines an exhaust port configured to connect to said suction source;
- and
- a front cover connected to the tool body, wherein the front cover and the rear wall together define an extraction nozzle volume having a suction inlet, and wherein the rear wall or the front cover defines an oppositely-disposed pair of air vents situated at a height above the suction inlet, wherein the air vents are formed in the rear wall, and wherein a center axis of each of the oppositely-disposed pair of air vents intersect the rear wall at a non-orthogonal angle.
A suction nozzle for use with an extraction cleaner having a suction source, comprising:
- a tool body having a rear wall;
- an exhaust port defined by the tool body, wherein the exhaust port is configured to connect to said suction source;
- an agitator assembly;
- and
- a front cover connected to the tool body and having a pair of side walls, wherein a lower edge of each side wall of the pair of side walls defines an arcuate notch, and wherein:
- the front cover and the rear wall together define an extraction nozzle volume having a suction inlet, wherein the agitator assembly is disposed adjacent to the suction inlet;
- the arcuate notch is configured to admit a slipstream into the extraction nozzle volume;
- and
- the rear wall defines a pair of air vents having respective center axes that intersect the rear wall at a non-orthogonal angle.
An extraction cleaner comprising:
- a housing;
- a suction source connected to the housing;
- and
- a suction nozzle comprising:
- a tool body having a rear wall;
- an exhaust port defined by the tool body, wherein the exhaust port is connected to the suction source;
- and
- a front cover connected to the rear wall such that the front cover and the rear wall together define an extraction nozzle volume having a suction inlet, wherein the rear wall defines an oppositely-disposed pair of air vents situated at a height above the suction inlet, each respective one of the air vents having a respective center axis that intersects the rear wall at a non-orthogonal angle.
