Description

Technical Field

[0002] High-speed hair dryers are very popular among consumers. With the miniaturization design of hair dryers, the volume of existing high-speed blower motors needs to be reduced. Existing high-speed blower motors generally use a terminal block connection method, that is, the PCB board is welded to the terminal block, and then the terminal block is welded to the motor. Due to the height limitation of the terminal block itself, the overall height of the motor increases after being assembled into a motor, thereby increasing the volume of the finished hair dryer, which is not conducive to the application of subsequent miniaturized products; and if the terminal block is directly removed and directly welded on the outside of the PCB board, the consistency of the welding solder joints is relatively poor, which will lead to inconsistent product height after welding.
