[0039] The following will be combined with the attached Figure 1-9 A detailed introduction to this application is given.

[0040] The present application provides a hair dryer, including a detachably connected hair dryer body and a plurality of hairdressing accessories. The user can use the hair dryer body in conjunction with the plurality of hairdressing accessories to blow out various styles, thereby meeting the user's various usage requirements. Specifically, the hair dryer body includes an air inlet, an air outlet, a fan unit, and a heating unit. The external airflow enters the interior of the hair dryer body from the air inlet under the action of the fan unit, and becomes a hot airflow after being heated by the heating unit and is discharged from the air outlet; the hair dryer body includes a cylindrical main body and a handle connected to the main body. The air outlet of the hair dryer is arranged at one end of the main body, and the user can hold the handle of the hair dryer to style the hair. The main body includes a hollow main body bracket 2 and a main body shell 1 arranged outside the main body bracket 2, and the handle includes a hollow handle bracket 4 and a handle shell 5 arranged outside the handle bracket 4.

[0041] The hair dryer of this solution has multiple hairdressing accessories, each of which has different styling functions. In order to improve the user experience, a control device 6 and an identification device 3 are provided on the hair dryer body. The identification device 3 includes a trigger rod 31 and a micro switch 32. An indicator light 48 is also provided on the hair dryer body. The control device 6 is configured to light up the indicator light 48 according to the triggering state of the micro switch 32. More specifically, the control device 6 controls the indicator light 48 to display different colors corresponding to different hairdressing accessories.

[0042] Furthermore, different hairdressing accessories of the present solution generally need to match different heating powers and wind speeds, so the identification device 3 includes multiple trigger rods 31 and multiple micro switches 32. Different hairdressing accessories trigger different micro switches 32. The control device 6 has built-in control programs corresponding to different hairdressing accessories. The control device 6 is configured to execute the corresponding control program according to the triggering state of the micro switch 32. That is, the identification device 3 not only has the function of identifying whether the hairdressing accessory is in place, but also has the function of identifying what kind of accessory it is. In this example, different hairdressing accessories may also trigger different numbers of micro switches 32. The identification of different accessories is achieved by mechanical means, and the identification is highly reliable.

[0043] In the present application, the main body bracket 2 is a hollow cylindrical structure, and a fan unit and a heating unit are installed inside the main body bracket 2; it can be understood that the heating unit is arranged in the main body, and the fan unit is arranged in the handle. An air duct is formed inside the main body bracket 2, and a heating unit is provided at the end of the main body bracket 2 near the air outlet. In order to prevent the heat of the heating unit from being transferred to the trigger rod 31, causing the trigger rod 31 to overheat, deform, and trigger failure, an interlayer space 100 is formed between the main body shell 1 and the main body bracket 2 of the present application, and the trigger rod 31 is installed in the interlayer space 100. Since the interlayer space 100 is separated from the air duct inside the main body bracket 2, the temperature in the interlayer space 100 is relatively low, and the probability of deformation of the trigger rod 31 is low, thereby improving the reliability of the hair dryer.

[0044] Specifically, the trigger rod 31 is in a Z shape, and includes a first rod body 311, a second rod body 312, and a third rod body 313 connected between the first rod body 312 and the second rod body 311. The first rod body 311 and the second rod body 312 are not in the same straight line. One end of the first rod body 311 is used to trigger the hairdressing attachment, and the other end of the first rod body 311 is connected to the third rod body 313. One end of the second rod body 312 is connected to the third rod body 313, and the other end of the second rod body 312 is used to trigger the micro switch 32. With such a configuration, space can be reasonably utilized, the main body can be designed to be smaller, and the cost can be reduced while improving the aesthetics. In addition, the trigger rod 31 is installed on the main body bracket 2, and a return spring 33 is provided between the trigger rod 31 and the main body bracket 2. When a part of the hairdressing accessories is installed on the hair dryer body, the trigger rod 31 is pushed to move and compress the return spring 33. When the hairdressing accessories are removed from the hair dryer body, the trigger rod 31 returns to its original position under the action of the return spring 33, so as to facilitate the detection of the hairdressing accessories installed next time.

[0045] In the present application, the control device 6 is arranged in the handle, and the handle includes a hollow handle bracket 4 and a handle housing 5 sleeved on the outside of the handle bracket 4.

Specifically, the outer periphery of the handle bracket 4 is provided with a limiting protrusion 45 and a buckle 44. The limiting protrusion 45 is arranged around the outer periphery of the micro switch 32 to limit the micro switch 32, and the buckle 44 fixes the micro switch 32 to the outer periphery of the handle bracket 4.

[0046] Since the micro switch 32 needs to be electrically connected to the control device 6, the wire 321 of the micro switch 32 needs to pass through the handle bracket 4 and enter the space inside the handle bracket 4. The space inside the handle bracket 4 is connected to the internal space of the main body bracket 2. Therefore, the handle bracket 4 of the present application is provided with a wire passing hole 41 for allowing the wire 321 of the micro switch 32 to pass through. The wire passing hole 41 is located below the micro switch 32. A seal is provided at the wire passing hole 41. The seal has a notch on its periphery. The wire 321 of the micro switch 32 is inserted into the center of the seal through the notch.

[0047] The control device 6 is provided with an indicator light 48, which can light up the indicator light 48 according to the triggering state of the micro switch 32, to prompt the user the type of hairdressing accessory selected and whether the hairdressing accessory is assembled in place. Specifically, the indicator light 48 of the present application is installed on the handle.

[0048] In a preferred embodiment, a light shielding member 47 is provided on the indicator light 48, and the light shielding member 47 includes a light-transmitting area corresponding to the position of the indicator light 48 and a light-shielding area arranged on the periphery of the light-transmitting area. The handle bracket 4 is also provided with a light panel 46, and a first light-transmitting hole 7 is opened at the position of the light panel 46 corresponding to the indicator light 48, and the light shielding member 47 is snap-fitted with the light panel 46.
