[0041] Example

[0042] A method of using a hair dryer, applied to the hair dryer described in Example 8, includes the following steps: The diffuser nozzle is attached to the hair dryer body (14) by the attraction of the first magnetic component (9) and the second magnetic component (15); When the hair dryer is working, the airflow blown out by the hair dryer body (14) passes through the air channel (3) of the lower shell (2) of the nozzle and several ventilation holes (12) and several toothed columns (4) of the upper shell (1) of the nozzle and blows it onto the user's hair.

[0043] Specifically, in combination Figure 9 As shown, the method of using a hair dryer includes the following steps: 1) The diffuser nozzle is attached to the hair dryer body 14 by the first magnetic attachment 9 and the second magnetic attachment 15 engaging and connecting; 2) Turn on the power of the hair dryer and start working.
