A pivoting handle keeps the grip upright above the center of gravity in both modes, enabling balanced one-handed blower and vacuum use.

A flexible elbow, rigid insert, and motorized gear drive keep blower airflow directed across a wide arc with low turbulence.

Pressure-driven airflow through pipe wall holes cools the control circuit unit without adding a separate cooling structure.

A widened fan-side flow area and protected wire routing help this handheld blower extend runtime, improve airflow, and reduce fatigue.

Integrated chassis alignment, preset nozzle angles, and resume throttle control cut setup effort, fuel use, and noise during turns.

Movable deflectors and outlet control let a portable blower redirect and split pressurized air quickly, improving ground coverage and user handling.

Rear volute placement and central battery layout increase air intake, improve balance, and reduce strain in a battery-powered backpack blower.

A rear-facing volute and balanced battery-motor layout increase air intake area, improve airflow, and reduce user fatigue.

By reversing fan rotation, one suction pipe handles both vacuum and blower modes, simplifying layout while preserving conveying performance.

A frustro-conical cyclone separates garden waste from dirty fan airflow to prevent clogging, dust exposure, and suction loss.

Offset outlet projections disturb the high-speed air jet, shifting noise frequency bands and lowering blower tube noise.

Flexible front and rear handle arms cut front-back vibration while preserving directional rigidity and blower control.

A handle-mounted adjustable light lets leaf blower users illuminate the airflow area in low light without adding separate flashlights or headlamps.

Deflected outlet airflow creates transverse force to pivot the blower tube, cutting operator effort and improving ergonomic control.

A movable outer pipe shifts the outlet and draws in extra air, letting one portable blower switch between high-speed and high-volume airflow.

A pivoting door and cam lock secure the vacuum tube to the blower intake, simplifying mode changes and reducing manual adjustment.

A cam-and-blocking-plate interlock prevents motor start unless the attachment is secured and quickly brakes the fan when removed.

An axial fan with a downward suction elbow and smooth converging pipe cuts blower noise and energy use while maintaining airflow.

Fixed internal passages create a side-to-side airstream, sweeping debris efficiently without operator motion or complex moving parts.
