摘要： A backpack working machine may be configured to eject liquid. The backpack working machine may include: a body unit; and a shoulder harness unit attached to the body unit and configured to be worn on shoulders of a user. The body unit may include: a battery unit comprising a battery attaching part to which a battery is attached; a fan unit comprising a fan configured to operate on electrical power of the battery; and a liquid tank configured to store the liquid. When the backpack working machine is placed on a placement surface, a direction perpendicular to the placement surface may be defined as an up-down direction. When the backpack working machine placed on the placement surface is viewed from above, 50% or more of the battery unit, 50% or more of the fan unit, and 50% or more of the liquid tank may overlap each other.

摘要： 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.

摘要： An electrically powered gardening tool of the type which includes a speed-reduction gear mounted in place to be driven by operation of an electric motor, a crank-cam in the form of overlapped eccentric disk plates fixed to a bottom surface of the speed-reduction gear by means of connecting pins for rotation therewith, and a pair of relatively reciprocating shear blades assembled with the eccentric disk plates. In the gardening tool, an elastic bushing is disposed in a mounting hole formed in the speed-reduction gear or each eccentric disk plate of the crank-cam for engagement with the connecting pins fixed to the eccentric disk plate or the speed-reduction gear, and a stopper is provided to restrict deformation of the elastic bushing caused by load applied to the crank-cam.

摘要： An electrically powered garden tool includes an electric motor mounted upright within an outer shell housing, a pair of relatively reciprocating shear blades assembled to be driven by operation of the motor through a crank mechanism provided within a lower portion of the outer shell housing, and a cooling fan assembled to be driven by operation of the motor for introducing outside air into an upper portion of the outer shell housing to exhaust the introduced air from a lower portion of the outer shell housing. In the garden tool, a downward exhaust opening is formed within a lower end peripheral wall of the outer shell housing enclosing the crank mechanism such that the air spouted by rotation of the cooling fan blows out downward from the downward exhaust opening to restrain the occurrence of blowing noise of the air.

摘要： A mist blower may include: a liquid tank configured to store liquid; a fan; an ejection tube through which air delivered by the fan flows; a liquid nozzle body disposed inside the ejection tube and configured to inject the liquid stored in the liquid tank into the ejection tube; and a facing body being away from the liquid nozzle body. The liquid nozzle body may comprise: a liquid passage through which the liquid flows and which comprises a constricted part having a minimum diameter; and a nozzle side surface along which air delivered by the fan flows. The liquid may be ejected from an ejection hole of the constricted part. The facing body may comprise: a facing surface that faces the ejection hole; and a facing body side surface connected to the facing surface and along which air delivered by the fan flows.

摘要： A mist blower in one aspect of the present disclosure includes an air blower, an air feed pipe, a tank, a liquid feed pipe, a nozzle, a first electromagnetic valve, a controller, and a first manual switch. The first electromagnetic valve (i) opens the liquid feed pipe in response to the first electromagnetic valve being activated and (ii) closes the liquid feed pipe in response to the first electromagnetic valve being deactivated. The controller activates or deactivates the air blower and the first electromagnetic valve. The first manual switch (i) is manually moved by a user of the mist blower and (ii) commands the controller to activate or deactivate the air blower based on a movement of the first manual switch.
