A blower (100) includes a blower attachment housing (112), a power head housing (122) having a handle (130) operably coupled thereto, a motor (140) disposed in the power head housing (122), a fan (160) disposed in the blower attachment housing (112), a battery (150), and an intake chamber (174) disposed between the motor (140) and the fan (160) to enable the air to enter the blower (100) between the motor (140) and the fan (160).

The present invention is directed to an outdoor blower that is capable of safely releasing any electrostatic charge that builds up in the blower. During the operation of the blower, electric charge builds up in the housing and components of the blower as particles in the air are moved through the blower. The blower includes a wire contact in the handle that is electrically connected to various other components in the blower. As electric charge is built up in the blower, it can be passed to the wire contact, which is graspable by a user, who acts as a ground and is able to release any charge that builds up.

Provided is an axial flow blower capable of improving an intake efficiency even when air is introduced from a plurality of suction openings. An axial flow blower includes a housing including an air blowing passage extending from a plurality of suction openings (lateral suction opening and lower suction opening) to an ejection opening, an electric motor, and an air blowing fan that blows air from the plurality of suction openings (lateral suction opening and lower suction opening) toward the ejection opening. An air blowing guide member is provided closer to the plurality of suction openings (lateral suction opening and lower suction opening) than to the air blowing fan, inside of the plurality of suction openings (lateral suction opening and lower suction opening). The air blowing guide member guides air introduced into the air blowing passage from the plurality of suction openings (lateral suction opening and lower suction opening) toward the air blowing fan.

Provided is an axial flow blower capable of effectively increasing a wind speed while suppressing decrease in a wind volume. The axial flow blower includes a housing including an air blowing passage extending from a suction opening to an ejection opening, an electric motor, and an air blowing fan that blows air from the suction opening toward the ejection opening. The housing is provided with a blow-out pipe that forms a portion of the air blowing passage extending in a direction along a rotation axis of the air blowing fan and has a distal end opening serving as the ejection opening, and a distal end portion of the blow-out pipe formed of a straight pipe is provided with an R part (first R part) formed of an outwardly rounded arc.

An information processing device includes a vegetation analysis section configured to analyze a vegetation state of a monitoring area on the basis of detection information acquired from a detection unit and indicating a status of the monitoring area, a restricted area determination section configured to define a restricted area, where entry is restricted, in the monitoring area on the basis of the vegetation state, and a guidance information providing section configured to provide a terminal device with guidance information indicating restrictions on entry into the restricted area.

A concentrator nozzle attachment for a blower device is disclosed that increases the airflow velocity of the blower without sacrificing the field of the jetting air. The concentrator nozzle is formed of an outer ring with a centrally located guide surface and is placed at the exit of an air tube. As the air exits the air tube, it's forced to flow around the guide surface, thus increasing its velocity. The attachment is secured to the end of the air tube and so does not alter the outer diameter through which the air exits. In this way, air velocity is increased without reducing its effectiveness.
