When the device detection switch SW2 detects that the hair setting device 2 is not mounted at the outlet of the blower body 1, the device detection switch SW2 generates a non-mounted signal and sends the non-mounted signal to the controller U1; then the normal function switch SW3 is closed, when the controller U1 receives the uninstall signal and detects that the normal function switch SW3 is closed, the controller U1 controls the blower body 1 to enter the normal function mode; then the additional function switch SW1 is closed, when the controller U1 detects that the additional function switch SW1 is closed, the controller U1 controls the blower body 1 to switch from the normal function mode to the additional function mode;
when the device detection switch SW2 detects that the hair setting device 2 is mounted at the outlet of the hair dryer body 1, the device detection switch SW2 generates a mounted signal and sends the mounted signal to the controller U1; then the normal function switch SW3 is closed, when the controller U1 receives the installed signal and detects that the normal function switch SW3 is closed, the controller U1 controls the hair dryer body 1 to realize the standby mode; when the hair dryer body 1 enters the standby mode, the additional function switch SW1 is closed, and when the controller U1 detects that the additional function switch SW1 is closed, the controller U1 controls the hair dryer body 1 to be started; in contrast, when the controller U1 detects that the additional function switch SW1 is turned off, the controller U1 controls the blower body 1 to stop.

In view of fully realizing the functions of the hair dryer body 1, the invention further comprises a cold air controllable switch T1 and a hot air controllable switch T2 which are respectively connected between the controller U1 and the hair dryer body 1, and it should be noted that the initial states of the cold air controllable switch T1 and the hot air controllable switch T2 are both off states.
Specifically, when the hairdressing device 2 is not mounted at the outlet of the hair dryer body 1, the device detection switch SW2 sends a non-mounting signal to the controller U1; at the moment, the normal function switch SW3 is shifted to a cold air gear LOW, when the controller U1 receives an uninstalled signal and detects that the normal function switch SW3 is located at the cold air gear LOW, the controller U1 controls the cold air controllable switch T1 to be closed, a motor MD and a fan blade in the hair dryer body 1 are started, cold air entering from an air inlet is blown out from an air outlet of the hair dryer body 1 under the centrifugal force action of the fan blade, and therefore the hair dryer body 1 can realize a cold air mode; at this time, the additional function switch SW1 is pressed to close the additional function switch SW1, when the controller U1 detects that the additional function switch SW1 is closed in the cold air mode, the controller U1 controls the cold air controllable switch T1 to be kept closed and controls the hot air controllable switch T2 to be closed at the same time, which means that the cold air controllable switch T1 and the hot air controllable switch T2 are both in a closed state at this time, so that the heating coil in the hair dryer body 1 heats cold air in the cavity, heated air is blown out from the air outlet of the hair dryer body 1, that is, the hair dryer body 1 enters the hot air mode, and the hair dryer body 1 is switched from the cold air mode to the hot air mode; conversely, by releasing the additional function switch SW1 to turn off the additional function switch SW1, the controller U1 controls the cool air controllable switch T1 to remain closed and simultaneously controls the hot air controllable switch T2 to be turned off, so that the air in the cavity of the hair dryer body 1 is still cool air, and the hair dryer body 1 is kept in the cool air mode.
When the hairdressing device 2 is not mounted at the outlet of the hair dryer body 1, the device detection switch SW2 sends a non-mounting signal to the controller U1; at the moment, the normal function switch SW3 is shifted to a hot air gear HIGH, when the controller U1 receives an uninstalled signal and detects that the normal function switch SW3 is in the hot air gear HIGH, the controller U1 respectively controls the cold air controllable switch T1 and the hot air controllable switch T2 to be closed, so that the outlet of the hair dryer body 1 can realize air blowing, cold air in the cavity can be heated, the air blowing of the hair dryer body 1 blows hot air, and the hair dryer body 1 realizes a hot air mode; at this time, the additional function switch SW1 is pressed to close the additional function switch SW1, when the controller U1 detects that the additional function switch SW1 is closed in the hot air mode, the controller U1 controls the cold air controllable switch T1 to be kept closed and controls the hot air controllable switch T2 to be switched off at the same time, so that the air outlet of the hair dryer body 1 can only blow out cold air, that is, the hair dryer body enters the cold air mode, and the hair dryer body 1 is switched from the hot air mode to the cold air mode; conversely, the additional function switch SW1 is released to turn off the additional function switch SW1, and the controller U1 controls the cold air controllable switch T1 and the hot air controllable switch T2 to be kept closed respectively, so that the air outlet of the cavity of the hair dryer body 1 blows out hot air, and the hair dryer body 1 is kept in the hot air mode.
When the hairdressing device 2 is not mounted at the outlet of the hair dryer body 1, the device detection switch SW2 sends a non-mounting signal to the controller U1; at this time, the normal function switch SW3 is toggled to the stop gear OFF, that is, the blower body 1 is in the power-OFF state, the controller U1 is also in the power-OFF state, and the cold air controllable switch T1 and the hot air controllable switch T2 are turned OFF, so that the blower body 1 enters the stop state.
It can be seen that when no hairdressing device 2 is installed at the outlet of the hair dryer body 1, the normal function switch SW3 can normally realize the hot air mode or the cold air mode, and when the hair dryer body 1 is in the hot air mode or the cold air mode, the operation mode of course of the hair dryer body 1 can be switched by pressing the additional function switch SW1, and compared with the existing normal function mode, the additional function switch SW1 can assist the user to quickly switch the normal function mode, and the operation is convenient.
Similarly, when the hair dressing device 2 is mounted to the outlet of the hair dryer body 1, the device detection switch SW2 sends a mounted signal to the controller U1; at the moment, the normal function switch SW3 is shifted to a cold air gear LOW, and when the controller U1 receives an installed signal and detects that the normal function switch SW3 is in the cold air gear LOW, the controller U1 respectively controls the cold air controllable switch T1 and the hot air controllable switch T2 to be switched off, so that the hair dryer body 1 realizes a standby mode; at this time, the additional function switch SW1 is pressed to close the additional function switch SW1, and when the controller U1 detects that the additional function switch SW1 is closed in the standby mode, the controller U1 controls the cold air controllable switch T1 to be closed, so that the air outlet of the hair dryer body 1 blows out cold air, and the hair dryer body 1 realizes the cold air mode; conversely, the additional function switch SW1 is released to turn off the additional function switch SW1, and the controller U1 controls the cool air controllable switch T1 to turn off, so that the blower body 1 is maintained in the standby mode.
When the hair dressing device 2 is mounted to the outlet of the hair dryer body 1, the device detection switch SW2 sends a mounted signal to the controller U1; at the moment, the normal function switch SW3 is shifted to a cold air gear LOW, and when the controller U1 receives an installed signal and detects that the normal function switch SW3 is in a hot air gear HIGH, the controller U1 respectively controls the cold air controllable switch T1 and the hot air controllable switch T2 to be switched off, so that the hair dryer body 1 realizes a standby mode; at this time, the additional function switch SW1 is pressed to close the additional function switch SW1, and when the controller U1 detects that the additional function switch SW1 is closed in the standby mode, the controller U1 controls the cold air controllable switch T1 and the hot air controllable switch T2 to be closed respectively, so that the air outlet of the hair dryer body 1 blows out hot air, and the hair dryer body 1 realizes the hot air mode; conversely, the additional function switch SW1 is released to turn off the additional function switch SW1, and the controller U1 controls the cold air controllable switch T1 and the hot air controllable switch T2 to turn off, respectively, so that the blower body 1 maintains the standby mode.
When the hair setting device 2 is not mounted at the outlet of the hair dryer body 1, the normal function switch SW3 is toggled to the stop position OFF, and as can be seen from the above, the hair dryer body 1 enters the stop state.
Therefore, when the hair dressing device 2 is installed at the outlet of the hair dryer body 1, and the normal function switch SW3 is adjusted to the cold air gear LOW or the hot air gear HIGH, the hair dryer body 1 is always in the standby mode, so that the hair dryer body 1 cannot realize the normal function mode; when the normal function switch SW3 is in the cold air position LOW, the blower body 1 is directly in the cold air mode by pressing the additional function switch SW 1; when the normal function switch SW3 is in the hot wind position HIGH, the blower body 1 is directly put into the hot wind mode by pressing the additional function switch SW 1; therefore, the hair dryer body 1 can be started and stopped conveniently through the additional function switch SW1, a user does not need to frequently adjust the normal function switch SW3 with multiple gears, and the operation is convenient.
It should be noted that the additional function mode may be a wind speed adjusting mode or other modes besides the above-mentioned modes, and is not limited in particular.
In order to further enrich the functions of the hair dryer, the hot air controllable switch T2 comprises a low-grade controllable switch T21 and a high-grade controllable switch T22 which are respectively connected between the controller U1 and the hair dryer body 1, and correspondingly, the hot air mode comprises a high-heat mode and a low-heat mode, wherein the high-heat mode is that hot air with higher temperature is blown out from the air outlet of the hair dryer body 1 when the controller U1 respectively controls the cold air controllable switch T1, the low-grade controllable switch T21 and the high-grade controllable switch T22 to be simultaneously closed; similarly, the low-heat mode is that the air outlet of the hair dryer body 1 blows hot air with a lower temperature when the controller U1 controls the cold air controllable switch T1 and the low-level controllable switch T21 to be closed simultaneously respectively; thereby conveniently satisfy user's special demand, for example blow dry hair etc. fast, be favorable to promoting user experience and feel.

That is, when the hair dryer body 1 is normally operated by the normal function switch SW3 while the hairdressing device 2 is not mounted, the blue indicator lamp 33 is kept lighted.
When the controller U1 detects that the hair dryer body 1 is in the standby state, the controller U1 controls the yellow indicator lamp 32 to be turned on and controls the red indicator lamp 31 and the blue indicator lamp 33 to be turned off respectively.
