Abstract: A blower may include an airflow pipe disposed between an inlet and an outlet, an axial flow fan including a hub and a plurality of blades, a drive shaft, an electric motor, a motor housing, a diffuser cone, a first vent defined on the diffuser cone, and a second vent defined between the hub and the motor housing. An airflow path in which air flows from the inlet to the outlet is defined in the airflow pipe. A circulation path in which the air flows from the first vent to the second vent is defined in the airflow pipe. When a circumferential end of the second vent on the inlet side is a first end and a circumferential end of the second vent on the outlet side is a second end, an outer diameter of the first end is larger than an outer diameter of the second end.

Abstract: A power blower includes a power blower main body and a blower tube member. The main body takes in air through an air intake portion by rotation of a blower fan rotated by a motor and discharges the air from an air discharge portion. The blower tube member has an opening on a base end side through which air discharged from the air discharge portion of the main body flows in, and an opening on a tip end side from which the air which has flowed in, is blown out. When a plane perpendicular to an axis of the blower tube member is in contact with the opening at the tip end side of the blower tube member, blown-air passages are formed on opposite sides of contact portions of the opening at the tip end side of the blower tube member and the plane.

Abstract: A mist blower may include: a liquid nozzle configured to inject liquid stored in a liquid tank into an ejection tube. The liquid nozzle may include: an end surface disposed on a distal end of the liquid nozzle, an ejection opening being defined in the end surface; a side surface constituting at least a part of an outer shape of the liquid nozzle; and a corner part connecting the end surface and the side surface and constituting a corner of the liquid nozzle. At the corner part, a virtual end surface defined by extending the end surface and a virtual side surface defined by extending the side surface may intersect at a first point. Each of a distance from the first point to the end surface and a distance from the first point to the side surface may be equal to or less than 0.3 mm.

Abstract: A blower may include a motor; a centrifugal fan configured to rotate with rotation of the motor; a casing configured to guide air from a suction port to a discharge port; a trigger configured to be pressed; and a control board configured to control rotation of the motor. The control board may include a normal mode and a low speed mode. In the normal mode, the control board may be configured to adjust a rotation speed of the motor in accordance with a degree by which the trigger is pressed. In the low speed mode, the control board may be configured to adjust the rotation speed of the motor to a target rotation speed, wherein the target rotation speed is lower than a maximum rotation speed of the motor that is achieved when the degree by which the trigger is pressed is a maximum degree in the normal mode.
