[0002] A hair dryer, also known as a hairdryer or hair dryer, is a hair styling device that uses electricity to heat air and output high-speed airflow to quickly dry or style hair. It is one of the most commonly used hair styling devices in people's daily lives. Currently, hair dryers on the market mainly include ordinary hair dryers and negative ion hair dryers. Ordinary hair dryers heat air with heating wires and output the hot air through a fan. They are easy to operate, but may make hair dry, frizzy, or even damaged during use. Negative ion hair dryers release negative ions, reducing static electricity and making hair smoother. They are better at protecting hair quality and reducing frizz. However, regardless of the type of hair dryer, its product structure is relatively fixed. It can only output airflow in a directional manner according to the fixed airflow output structure. It cannot adjust the airflow output direction according to the needs of hair styling, making it inflexible and not user-friendly. Summary of the Invention

The other end of the second male connector is provided with a second retaining edge, and the third fastening groove and the fourth fastening groove are fastened together on the second retaining edge.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Its steering connection structure forms an inner steering component through the first inner steering housing and the second inner steering housing. The turning structure design of the inner steering component allows airflow to enter the inner steering component through the first male connector. Under the guiding effect of the airflow direction of the inner steering component, the airflow is output from the first female connector, thereby realizing the change of airflow direction.

[0016] 2. The L-shaped design of the first connecting groove of the first male connector and the second connecting groove of the second male connector, after the first male connector or the second male connector is connected to the corresponding second female connector or the first female connector, makes it difficult for the first connecting block or the second connecting block to detach from the corresponding second connecting groove or the first connecting groove due to the corner design of the first connecting groove and the second connecting groove; in conjunction with the unidirectional arrangement of the first connecting groove or the second connecting groove, the first connecting groove of the first male connector or the second connecting groove of the second male connector rotates into contact with the second connecting block of the corresponding second female connector or the second connecting block of the first female connector, thus enabling... Easily achieve component connection between the first male connector and the second female connector, or between the second male connector and the first female connector; both the first connecting block of the first female connector and the second connecting block of the second female connector have at least one outwardly curved structure. Through the curved design of the first and second connecting blocks, the first and second connecting blocks can slide more smoothly into their respective first and second connecting slots; when disassembly is required, simply rotate the first male connector and / or the second male connector in the opposite direction to disengage the first and / or second connecting slots from their respective second or first connecting blocks, making assembly and disassembly simple and quick;

[0017] 3. By engaging the first latch of the first latch and / or the second latch of the second latch with the first locking position of the first male connector or the second locking position of the second male connector, the connection between the first male connector and the second female connector, the second male connector and the first female connector, or the second male connector and the second female connector is limited. This effectively prevents the first male connector and the second female connector, the second male connector and the first female connector, or the second male connector and the second female connector from loosening after connection, ensuring the stability of the structural connection between the components of this utility model. When it is necessary to disassemble the components, the first latch and the second latch are reset, and the first male connector or the second male connector can be rotated in the opposite direction to easily remove the first male connector or the second male connector from the first female connector or the second female connector.

[0018] 4. It is connected to the first male and first female connectors of the turning connection structure through the second female connector at one end of the main body of the hair styling device and the second male connector at one end of the air outlet component, respectively, forming an airflow turning structure between the main body of the hair styling device and the air outlet component, thereby turning the output airflow of the hair styling device; when the air outlet component is connected to the second female connector of the main body through the second male connector, the airflow of the hair styling device can be output in a straight line. Users can choose between straight airflow output or turning airflow output according to their daily styling needs. The airflow output direction can be switched flexibly, making it more user-friendly.

At the same time, each retaining block 111c of the first air vent connector 111 is connected to the first retaining hole 112c and the second retaining hole 113c respectively. Then, the first actuating part 143 of the first latch 14 passes through and protrudes from the first latching edge 121 of the steering housing 114. At the first buckle hole 114a, one end of the steering housing 114 is inserted through one end of the first air vent connector 111 of the inner steering component and sleeved on the outside of the inner steering component. Then, the first female connector 13 is sleeved on one end of the first air vent connector 111 of the inner steering component. At this time, the first buckle 131 of the first female connector 13 is respectively fastened in the first slot 112a of the corresponding first inner steering housing 112 and the second slot 113a of the second inner steering housing 113.

[0056] This specific embodiment is for illustrative purposes, and the technical features of Specific Embodiment 1 are used for explanation, which will not be repeated here.

[0057] During assembly, first, the end cap 7 is fitted onto one end of the power cord 6, and the power cord 6 is electrically connected to the control unit. Next, the control unit is placed between the first cavity component 221 and the second cavity component 222. Simultaneously, the first connecting hole 221a of the first cavity component 221 and the second connecting hole 222a of the second cavity component 222 are respectively fastened to the corresponding connecting protrusions 211 of the guide member 21, so that the first cavity component 221 and the second cavity component 222 are engaged. Then, the second actuating part 872 of the second latch 87 is passed through and protrudes into the second latching hole 235 of the outer sleeve 23. Finally, one end of the outer sleeve 23 is fitted onto the guide member 21, covering the outside of the guide member 21 and the inner cavity 22. Then, the second anti-fooling groove 86 of the second female connector 8 is inserted into the corresponding anti-fooling strip 236 of the outer casing 23, and the second female connector 8 is sleeved on one end of the guide member 21. At this time, the limiting buckle 84 of the second female connector 8 is engaged with the limiting protrusion 231 of the outer casing 23, and the limiting protrusion 232 of the outer casing 23 is engaged with the corresponding limiting groove 85 of the second female connector 8.

Thus, the assembly of the main body 2 and the second female connector 8 is completed.

[0058] Furthermore, the third groove 311 of the first inner air outlet housing 31 and the fourth groove 321 of the second inner air outlet housing 32 are fastened together onto the second locking edge 93 of the second male connector 9. Then, the air outlet housing 33 is sleeved on the outside of the first inner air outlet housing 31 and the second inner air outlet housing 32. At this time, the inner locking block 331 of the air outlet housing 33 is respectively locked onto the first locking position 312 of the first inner air outlet housing 31 and the second locking position 322 of the second inner air outlet housing 32, thus completing the assembly of the air outlet assembly 3 and the second male connector 9.

[0059] In daily use, the second connecting slots 91 of the second male connector 9 at one end of the air outlet assembly 3 are rotated relative to the second connecting blocks 81 of the second female connector 8, so that each second connecting block 81 slides into the corresponding second connecting slot 91. Then, the second actuating part 872 of the second latch 87 is moved towards the air outlet assembly 3, so that the second latching part 871 of the second latch 87 is fastened on the corresponding second locking position 92, thereby limiting the rotation of the second male connector 9 and ensuring that the air outlet assembly 3 is stably connected to the main body 2. At this time, the power switch is turned on by the power button 25 to start the invention, and the control unit moves towards the air outlet assembly 3. The motor in the main body 2 issues a command to drive the motor blades, which in turn drive the fan blades to deliver the airflow in the inner cavity 22 of the main body 2 to one end of the second guide section 212 of the guide member 21. The airflow then passes through the second air outlet 213 and the second female connector 8 and is output from the inner air outlet member formed by the first inner air outlet housing 31 and the second inner air outlet housing 32. The user can also use the touch key 24 to adjust the mode (such as switching the wind speed and / or temperature mode). At this time, the airflow is output in a straight line from the main body 2 to the air outlet assembly 3. After use, the power switch is turned on by using the power button 25 to turn off the utility model.

[0060] When it is necessary to change the airflow output direction of the main body 2, the first connecting slots 122 of the first male connector 12 at one end of the deflection connection structure 1 are respectively rotated and connected to the second connecting blocks 81 of the second female connector 8, so that each second connecting block 81 slides into the corresponding first connecting slot 122. Then, the second actuating part 872 of the second latch 87 is moved towards the deflection connection structure 1, so that the second latching part 871 of the second latch 87 is fastened to the corresponding first locking position 123 of the first male connector 12, thereby limiting the rotation of the first male connector 12 and making the deflection connection structure 1 stably connected to the main body 2. Next, the second connecting slots 91 of the second male connector 9 at one end of the air outlet assembly 3 are respectively rotated and connected to the first connecting blocks 132 of the first female connector 13, so that each first connecting block 132 slides into the corresponding second connecting slot 91. Then, the first actuating part 143 of the first latch 14 is moved towards the air outlet assembly 3, so that the first latching part 143 of the first latch 14 is fastened to the corresponding first locking position 142. 2 is fastened to the corresponding second locking position 92 of the second male connector 9, and the second male connector 9 is rotated and limited, so that the air outlet assembly 3 is stably connected to the steering connection structure 1. At this time, the power switch is turned on by the power button 25 to start the utility model. The control unit sends a command to the motor in the main body 2 to turn the motor. The motor drives the fan blades, so that the airflow in the inner cavity 22 of the main body 2 is delivered to one end of the second guide part 212 of the guide member 21, and through the second air outlet 213 and the second female connector 8, it is delivered from the inner steering member composed of the first inner steering housing 112 and the second inner steering housing 113 to the air outlet assembly 3, and output from the air outlet assembly 3. Due to the turning structure design of the inner steering member, the airflow is turned and guided, so that the airflow output by the main body 2 achieves the effect of turning the output. The user can also use the touch key 24 to adjust the mode of the touch button (such as switching the wind speed and / or temperature mode). After use, the power switch is turned on by the power button 25 to turn off the utility model.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
