An assembly including a wearable blower having a fan, a motor, an air duct having a duct housing thereof, a handle attached to the duct housing, and a hanger disposed on the duct housing. The hanger has an attachment part attached to the duct housing and adjacent to the handle and a hanger part connected to the attachment part for holding an accessory attached to the blower. The hanger part rotates with respect to the duct housing at a first hanging position whereat the hanger part is unfolded with an opening mouth for holding the accessory of the blower and the hanger part rotates with respect to the duct housing at a second folded position. Thus, the arrangement of the hanger can help the user to hold the accessory of the blower at the work states.

An electrical apparatus includes first and second battery interfaces disposed on a housing for electrically and mechanically connecting first and second battery packs in series. A controller is disposed within the housing and includes an apparatus microprocessor that receives first and second communication signals respectively outputted from respective microprocessors of the first and second battery packs. A first signal communication path communicates the first communication signal from the first battery pack microprocessor to the apparatus microprocessor by shifting a first voltage range of the first communication signal to a second voltage range that is suitable for inputting into the apparatus microprocessor. A second signal communication path communicates a third communication signal from the apparatus microprocessor to the first battery pack microprocessor by shifting the second voltage range of the third communication signal to a first voltage range that is suitable for inputting into the first battery pack microprocessor.

The present invention provides a blower with reduced noise. The blower comprises a blower main body incorporating a centrifugal fan. The blower main body is configured to suck air from both sides of the blower main body by rotation of the centrifugal fan. The centrifugal fan includes a support plate having a rotation center and a plurality of blades provided on each of a first surface and a second surface of the support plate. A position of at least part of the plurality of blades on the first surface and a position of at least part of the plurality of blades on the second surface are misaligned in a circumferential direction, and/or a number of the plurality of blades on the first surface differs from a number of the plurality of blades on the second surface.

A outdoor power equipment system includes a removable rechargeable battery module, a robotic lawn mower, and a portable power equipment. The robotic lawn mower includes a receptacle configured to receive the battery module, and an electric motor electrically coupled to the receptacle to receive electricity to drive at least one of a wheel and a cutting implement. The portable power equipment includes a receptacle configured to receive the battery module, and at least one of an electric motor, a light source, and an amplification circuit coupled to the receptacle to receive electricity.

A blower includes a motor, a fan driven by the motor to rotate about a first axis, a power supply device, and a housing assembly accommodating the motor and including an inner duct and an outer duct assembly. The inner duct is formed with an inner air inlet. The outer duct assembly surrounds the inner duct. The outer duct assembly includes an outer duct and a hood, where the outer duct is disposed on a front side of the hood, an outer air outlet is formed at an end of the outer duct facing away from the hood, an outer air inlet is formed on the hood and has a front end portion and a rear end portion along a direction of the first axis, and the inner air inlet is disposed between the front end portion and the rear end portion along the direction of the first axis.

A debris-collecting apparatus includes a draft inducer operable to draw air and debris, an input portion for receiving incoming air and debris caused by operation of the draft inducer, and a bagging portion. The bagging portion includes a hood having an arcuate portion, a bag removably positioned below the hood and having an inner face, and a bagging passage for directing the air and debris from the input portion to the hood. The arcuate portion extends from the bagging passage to the bag such that the air and debris from the bagging passage travels along the arcuate portion and thereafter apply a dislodging force to dislodge debris collected at the inner face of the bag.
