Claims

[Scope of utility model registration request]

A cavity that communicates with the atmosphere is provided on the back wall of the airflow unstable region on the side wall of the once-through blower's discharge port, and the upper surface of this cavity is airtightly covered with a flexible thin film to prevent the unstable region from flowing depending on the operating status of the once-through fan. A once-through blower characterized by a flexible thin film that protrudes from the discharge port when pressure changes.
