1. A blower comprising:
- an impeller that is rotatable around a central axis extending vertically;
a motor that includes a stator and a rotor and that together with the rotor rotates the impeller;
a motor housing, at least a part of the motor housing being disposed on an outer side of the motor in a radial direction;
a blower housing that is disposed on an outer side of the impeller in the radial direction, and that opposes an outer surface of the motor housing in the radial direction with a gap therebetween;
an electronic component that is disposed below the stator in an axial direction; and
a circuit board that is disposed below the motor housing in the axial direction,wherein the motor housing includes a motor housing inlet that has a cylindrical shape extending in the axial direction, that extends below a lower end of the blower housing in the axial direction and surrounds an outer side of the electronic component in the radial direction, that is formed below the lower end of the blower housing in the axial direction, and that allows an inner side and an outer side of the motor housing in the radial direction to communicate with each other.

Abstract
A blower includes an impeller, a motor that rotates the impeller, an electronic component that is disposed below a stator in an axial direction, and a circuit board that is disposed below a motor housing in the axial direction. The motor housing includes a motor housing inlet that has a cylindrical shape extending in the axial direction, that extends below a lower end of a blower housing in the axial direction and surrounds an outer side of the electronic component in a radial direction, that is formed below the lower end of the blower housing in the axial direction, and that allows an inner side and an outer side of the motor housing in the radial direction to communicate with each other.
