Abstract
A tool to generate airflow including a housing that has an intake port and an outlet port, and an impeller coupled to the housing. The housing at least partially defines a volute between the intake port and the outlet port, and the impeller is in airflow communication with the volute to generate an airflow between the intake port and the outlet port through the volute. The tool includes an airflow guide that is disposed in the housing and that has an air intake portion with a volute wall partially defining the volute and disposed in close proximity to the impeller. The air intake portion defines the intake port and a passageway extends from the intake port toward the impeller along an airflow axis.
Claims17
A tool to generate airflow, the tool comprising:
- a housing including an intake port and an outlet port and partially defining a volute between the intake port and the outlet port;
- an impeller coupled to the housing and in airflow communication with the volute to generate an airflow between the intake port and the outlet port through the volute;
- and
- an airflow guide disposed in the housing and including an air intake portion having a volute wall separate from the housing, the volute wall partially defining the volute with the housing and disposed adjacent to the impeller, the air intake portion defining the intake port and a passageway extending from the intake port toward the impeller along an airflow axis.
A tool to generate airflow, the tool comprising:
- a housing including an intake port and an outlet port and at least partially defining a volute between the intake port and the outlet port, the intake port having an outer wall and an inner wall spaced radially inward from the outer wall by a gap;
- an impeller coupled to the housing and in airflow communication with the volute to generate an airflow between the intake port and the outlet port through the volute;
- and
- an airflow guide disposed in the housing and including an air intake portion at least partially defining the intake port and having a passageway extending from the intake port along an airflow axis, the passageway at least partially defined by an inner surface of the inner wall,
- wherein the inner surface has a curved profile.
