摘要： An air blower includes an impeller, a motor and a blower housing. The blower housing includes a first housing member for receiving the motor and a second housing member for receiving the impeller. The first and second housing members are mounted to each other. Two opposed air outlets are formed at an end of the first housing member remote from the second housing member. Each air outlet is formed by an outwardly inclined cutout. The cutout is bounded by two inclined sides. An angle A formed by each inclined side and an axial direction of the blower is in the range from 0 to 45 degrees. Radial lines extending from one inclined side of one air outlet and the adjacent inclined side of the other air outlet form an angle B in the range from 15 to 45 degrees.

摘要： A diffuser includes a body and diffusion blades disposed at a circumferential edge of the body. The body includes an air inlet side and an air outlet side. Each diffusion blade has an inclined guide surface. The guide surface has a starting end at the air inlet side of the body and a terminating end adjacent the air outlet side of the body. The guide surface extends from the starting end to the terminating end along a circumferential path and has a width gradually increasing from the starting ending to the terminating end. The diffuser further includes air outlets at the terminating ends of the guide surfaces. Each air outlet fluidly connects the terminating end of a corresponding one of the guide surfaces and the air outlet side of the body. A blower employing the diffuser is also provided.
