Air blower

Abstract

An air blower has a left cover, a right cover, a vented disk, an impeller and a motor. The motor is mounted at the same side with an air inlet. The vented disk is mounted on the right cover by multiple first screws, and the left cover is combined with the right cover by the first screws with the impeller received between the left cover and the right cover. The motor is mounted beside an exterior of the right cover and blades of the impeller face to the motor. Therefore, the direction of the air flow is over and around the motor, and the strong air flow can effectively cool the operating motor, which prolongs the operating life of the motor.

1 . An air blower comprising a left cover ( 2 ), a right cover ( 7 ) a vented disk ( 8 ), an impeller ( 4 ) and a motor ( 9 ), wherein the vented disk ( 8 ) is mounted on the right cover ( 7 ) by multiple first screws ( 1 ), and the left cover ( 2 ) is combined with the right cover ( 7 ) by the first screws ( 1 ) and forms a cavity wherein the impeller ( 4 ) is received; the motor ( 9 ) is mounted besides an exterior of the right cover ( 7 ) and the impeller ( 4 ) is connected with the motor ( 9 ) through a spindle; the impeller ( 4 ) has multiple blades that face to the motor ( 9 ).  
   
   
       2 . The air blower as claimed in  claim 1  wherein the motor ( 9 ) is secured in an enclosure ( 12 ) with at least one opening ( 122 ), a capacitor box ( 20 ) having a capacitor ( 18 ) and a power cable ( 16 ) therein is mounted on the motor box ( 12 ), and a switch ( 15 ) is mounted on a side of the capacitor box ( 20 ) and secured by a switch cover ( 14 ).
