A power tool () is disclosed comprising a tool (), a power source () arranged to power the tool (), a throttle lever (), a circuit board (), and a human machine interface () comprising components () arranged on the circuit board (). The power tool () further comprises a magnet () operably connected to the throttle lever (), and a sensor arrangement () configured to sense the intensity of the magnetic field of the magnet (). The sensor arrangement () is arranged on the circuit board ().

Hand held power tool with a human machine interface

A blower () may include a housing (), a motor (), a fan assembly () and an inlet assembly (). The housing () may include a handle () operably coupled thereto. The fan assembly () may be operably coupled to the motor () to force air through a blower tube () responsive to operation of the motor (). The blower tube () may define a tube axis (). The inlet assembly () may provide a path for air to the fan assembly (). The inlet assembly () may include an inlet aperture () formed at an end of the housing (). The inlet assembly () may further include an inlet mesh () disposed within the housing () spaced apart from the inlet aperture ().

Blower with improved sound reduction

A blower () may include a housing (), a blower tube (), a fan assembly () and an eyelet (). The housing () may include a handle portion () defining a handle aperture (). The blower tube () may extend forward from the housing () and define a tube axis (). The fan assembly () may be operably coupled to the blower tube () to force air through the blower tube () responsive to operation of a motor (). The eyelet () may be disposed on a side portion of the housing () proximate to the handle aperture ().

Blower comprising an eyelet

A blower may include a housing, a motor, a fan assembly and an aperture array. The housing may include a handle portion, a top wall and a bottom wall. The fan assembly may be operably coupled to the motor to force air through a blower tube responsive to operation of the motor. The blower tube may define a tube axis. The aperture array may be provided at a portion of the housing to provide a path for air to the fan assembly. The aperture array may be defined by a plurality of vanes disposed at a portion of the housing between the top wall and the bottom wall. The vanes may be angled downward relative to the handle portion.

Noise reduction system for a blower

A method of cooling blower components may include rotating a fan assembly () responsive to operation of a motor (). The rotation of the fan assembly may create an underpressure region in an inlet portion () and an overpressure region at a main channel () of the fan assembly (). The method may further include drawing air into the inlet portion () through a control unit housing portion () of a housing () of the blower () to cool a control unit () of the blower (), drawing air into the inlet portion () through a battery compartment () to cool a battery () of the blower (), and pushing air from the main channel () through a motor housing () to cool the motor ().
