Definitions

• the present disclosure relates to blowers and vacuums for outdoor use, specifically axial-fan or in-line type blowervac designs.
• FIG. 6 is a front view of the baffle of the tool of Fig. 1 ;
• the blowervac 10 can be operated either in a blowing mode or a vacuum mode.
• the flap 30 is moved between the two positions, and the motor direction is changed.
• a switch 44 located in the handle 14, controls power to the motor 36. Either AC or DC power can be provided.
• the switch 44 is connected to the motor through electrical wiring that is routed through the main housing 12, which has an inner layer 12a and outer layer 12b to house the wiring (see Fig. 3).
• the flap 30 In the blowing mode, the flap 30 is in the down position so that it covers the air exhaust 32.
• the motor rotates in a first direction where air is pulled in through the air inlet 20 and passes through the housing 12 to exit out of the airpipe 16. Because the air exhaust 32 is blocked by the flap 30, no air passes in this direction. Also, because the motor 36 is positioned outside of the main housing 12, eg. in the motor housing 40 below the main housing 12, the main housing's radial and longitudinal dimensions are reduced. Additionally, greater airflow efficiencies are achieved since the motor does obstruct the airflow path.
• the flap 30 has a non-planar circular shape with scoops 31 on a top surface.
• the scoops 31 have a rounded curved shape that function to help move the flap into the proper position.
• air is pulled in through the air inlet 20 and push the flap 30 downward into the blowing mode position.
• the rear portions of the scoops 31 smoothly transition with the flap 30 so that air flowing over the flap is not disrupted.
• the baffle 122 covers a bottom section of the rear portion 1 13 so that it blocks the air exhaust 32.
• the fan assembly 24 pulls air in through the air inlet 120, which then travels past the fan assembly 24 and ultimately out of the airpipe 16.
• the baffle 122 In the vacuum mode, shown in Fig. 10, the baffle 122 is rotated so that it covers a top section of the rear portion 1 13 to block the vents 114.
• the motor 36 and fan assembly 24 operate in reverse and pulls air in through the airpipe 16, past the fan assembly 24 and out through the air exhaust 32.
• a bag may be attached to air exhaust 32 to catch and collect any debris.
