BLOWER WITH CRUISE CONTROL AND BOOST FUNCTION |
| 摘要 |
A blower may (100) include a power unit and fan assembly powered by the power unit, a stepless trigger (146), control circuitry configured to at least partially control application of power to drive the fan assembly based on a position of the stepless trigger (146), and one or more buttons. The fan assembly may rotate at a speed proportional to the position of the stepless trigger (146) in a first mode of operation. The control circuitry may be configured to enable the operator to actuate a first button (164) of the one or more buttons to shift to a second mode of operation in which speed of the fan assembly is not proportional to the position of the stepless trigger (146) over at least a portion of a range of motion of the stepless trigger (146). |

1. A blower comprising:
a power unit and fan assembly powered by the power unit; a stepless trigger; control circuitry configured to at least partially control application of power to drive the fan assembly based on a position of the stepless trigger; and one or more buttons, wherein the fan assembly rotates at a speed proportional to the position of the stepless trigger in a first mode of operation, and wherein the control circuitry is configured to enable the operator to actuate a first button of the one or more buttons to shift to a second mode of operation in which speed of the fan assembly is not proportional to the position of the stepless trigger over at least a portion of a range of motion of the stepless trigger. |
