In the present embodiment, the air supply assembly 18 is composed of an air cavity cover 7, a motor stator 8, a motor rotor 9 and fan blades 10, see fig. 3. The fan blade 10 and the motor rotor 9 need to be subjected to strict dynamic balance test and can be used after being qualified.
In this embodiment, the control switch is divided into a main button switch 2 and a sub button switch 5, the main button switch 2 and the sub button switch 5 are cooperatively controlled, the main button switch 2 controls the power supply of the air blower to be turned on and off, the electric quantity indicator lamp 3 displays the electric quantity residual quantity of the lithium battery pack after the main button switch 2 is turned on, and the sub button switch 5 can only function when the main button switch 2 is turned on. The knob type sub-switch 5 is rotated to start the motor of the air feeder and adjust the air supply quantity.
In this embodiment, as shown in fig. 4, the control circuit board 15 is fixed inside the upper casing 1 at a position such that the push switch on the control circuit board 15 faces the push button of the push button type main switch installed on the upper casing 1, and the push button type main switch 2 is embedded inside the upper casing 1 and installed in an interference fit manner (see fig. 1) to ensure air tightness. The control circuit board 15 is fixed inside the upper case 1 in such a position that the potentiometer with switch on the control circuit board 15 is aligned with the knob mounted on the upper case 1. The control circuit board 15 is fixed in the upper casing 1, so that the positions of the five surface mount diodes on the control circuit board 15 face the five light emitting diode columns, the five light emitting diode columns are arranged in the five through holes in the top of the upper casing 1 of the air blower in a tight fit manner (see the attached drawing 1), and each light emitting diode column represents 20% of the electric quantity of the lithium battery pack.
