A blower including a base having a housing, a handle extending from the housing, a power source positioned within the housing, the blower including: a drive shaft extending forwardly from the power source, wherein the drive shaft is rotatable by the power source; a fan member operatively connected to the drive shaft; a flywheel extending rearwardly from the power source, the flywheel being positioned adjacent to a rear of the housing; and at least one rear vent formed into the rear of the housing adjacent to the flywheel, wherein rotation of the flywheel draws ambient air into the housing through the at least one rear vent, and rotation of the flywheel generates a cooling air flow that directs the ambient air across the power source to cool the power source during operation thereof.

A blower (100) may include a housing (110), a blower tube (150), a fan assembly (160) and an eyelet (190). The housing (110) may include a handle portion (144) defining a handle aperture (145). The blower tube (150) may extend forward from the housing (110) and define a tube axis (152). The fan assembly (160) may be operably coupled to the blower tube (150) to force air through the blower tube (150) responsive to operation of a motor (120). The eyelet (190) may be disposed on a side portion of the housing (110) proximate to the handle aperture (145).

A portable leaf blower comprises a housing having an air inlet and an air outlet port and defines an air outlet port axis. A handle is attached to the housing. A motor is mounted within the housing, with the motor mount having a rotatable drive shaft. A rotatable impeller is mounted on the drive shaft for rotation therewith, and to draw air into the air inlet and to blow the air out of the air outlet port in generally parallel relation to the air outlet port axis. A blower tube has a tube ingress port and a tube egress port, and defines a tube ingress port axis. The blower tube is connectable in supported relation to one of the housing and the handle, such that the tube ingress port is positioned in spaced relation to the air outlet port, with the air outlet port axis being coincident with the tube ingress port axis.

Disclosed is a blowing-suction device, comprising a housing; an air pipe extending along a longitudinal direction and connected to the housing; a motor located in the housing and providing rotational motion; and a fan rotationally generating an airflow; wherein when the fan operably rotates along a first direction, the blowing-suction device is in a blowing mode; and when the fan operably rotates along a second direction, the blowing-suction device is in a suction mode.

A blower/vacuum being interchangeable between a blower configuration and a vacuum configuration is provided. The blower/vacuum includes a blower assembly attachable to a base in the blower configuration and a vacuum assembly attachable to the base in the vacuum configuration. The blower/vacuum includes a fan member that has both a first fan and a second fan integrally formed together, wherein the first fan is utilized to generate air flow in the blower configuration and the second fan is utilized to generate air flow in the vacuum configuration.

The battery-powered blower includes a housing assembly including a first housing portion having a first inner surface, a second housing portion having a second inner surface, and connected to the first housing portion, and a third housing portion connected to the second portion. The third housing portion has a side outer surface configured to receive a battery. The battery is mountable to the side outer surface of the third housing portion. The second housing portion in connection with to the first housing portion forms an inner chamber therebetween. A fan is provided in the inner chamber to facilitate airflow through the housing assembly and out an outlet, and a motor is provided intermediate to the second housing portion and the third housing portion. The center of gravity with respect to the overall blower is provided proximate to a handle portion.

A back carrier has a back plate and a shoulder strap. The back plate has a longitudinal extent and, in the direction of its longitudinal extent, has an upper and a lower end section. The upper end section reaches as far as the upper end of the back plate. The strap extends on the back side of the back plate, which faces toward the back of a user. The strap is fastened with a first strap section in the area of the upper end section to an upper fastening location and is fastened with a second strap section in the area of the lower end section to a lower fastening location. In the area of the upper end section, the back plate has a recess for receiving an extension plate. In the direction of the longitudinal extent, the recess is open toward the upper end of the back plate.
