Abstract
A blower includes a body, a motor, and a single fan configured to rotate in response to rotation of a motor shaft to discharge air through a discharge opening. The maximum rotational speed of the motor shaft is within a range of 50,000 rpm to 120,000 rpm. An area of the discharge opening is changeable by a user. The blower is configured to selectively operate in a first mode or in a second mode according to the area of the discharge opening. In the first mode, the maximum blowing force of the air discharged through the opening is within a range of 2.5 N to 5.0 N when the motor is driven at the maximum rotational speed. In the second mode, the maximum dynamic pressure of the air discharged is within a range of 30 kPa to 65 kPa when the motor is driven at the maximum rotational speed.
Claims11
A blower comprising:
- a body having an inlet opening and a discharge opening;
- a motor housed in the body;
- a fan housed in the body and is configured to rotate in response to driving of the motor to generate a flow of air that is sucked through the inlet opening, passes through the motor and is discharged through the discharge opening;
- and
- at least one removably mounted filter arranged between the inlet opening and the motor within the body;
- wherein:
- the body includes (i) a filter mounting part that has an opening and within which the at least one filter is removably mounted and (ii) a cover that removably surrounds the opening of the filter mounting part and that removably surrounds the filter mounting part in a direction from the inlet opening to the discharge opening;
- and
- the at least one filter is removable from and mountable within the filter mounting part through the opening.
