[0036] When the hair dryer provided by the present application is in use, the user holds the hair dryer 100 and the handle 200 with both hands respectively, and then rotates them forcefully to open the folded hair dryer, and then operates it like a traditional hair dryer. After use, the user holds the hair dryer 100 and the handle 200 with both hands respectively and rotates them together to achieve folding to save space and facilitate travel, etc. The reliability when in use and the foldable feature when not in use embody the advantage of the compact structure of the hair dryer; in addition, by providing a power connection structure 700 between the handle 200 and the hair dryer 100, the power connection structure 700 can electrically connect the control panel 600 and the functional elements of the hair dryer, thereby providing wiring margin for the rotational movement between the handle 200 and the hair dryer 100, ensuring that the cables arranged between the handle 200 and the hair dryer 100 will not be broken due to the large rotation between the handle 200 and the hair dryer 100.

[0037] like Figure 3 and Figure 4As shown, optionally, the power connection structure 700 includes an electric ring 710 for electrically connecting to the functional elements of the hair dryer, the electric ring 710 is in contact and electrically connected to the control board 600, and the electric ring 710 can rotate synchronously with the hair dryer 100 or the handle 200 relative to the control board 600 when the hair dryer 100 rotates relative to the handle 200. Specifically, when the hair dryer 100 rotates relative to the handle 200, the electric ring 710 can rotate synchronously with the hair dryer 100 or the handle 200 relative to the control board 600, and the electric ring 710 always maintains contact and electrical connection with the control board 600, so that the electrical connection between the control board 600 and the functional elements of the hair dryer does not need to rely entirely on cables, thereby providing wiring margin for the rotational movement between the handle 200 and the hair dryer 100, ensuring that the cables arranged between the handle 200 and the hair dryer 100 will not be broken due to the large-scale rotation between the handle 200 and the hair dryer 100.

[0038] like Figure 4 As shown, further, the control board 600 and the electric ring 710 each include two, the two control boards 600 are respectively a first control board 601 and a second control board 602, the two electric rings 710 are respectively a first electric ring 711 and a second electric ring 712, the voltage of the first electric ring 711 is less than the voltage of the second electric ring 712, the first electric ring 711 is in contact and electrically connected with the first control board 601, and the first electric ring 711 can rotate synchronously with the hair dryer 100 or the handle 200 relative to the first control board 601 when the hair dryer 100 rotates relative to the handle 200, the first electric ring 711 is used to be electrically connected to the low-voltage functional element of the hair dryer, the second electric ring 712 is in contact and electrically connected with the second control board 600, and the second electric ring 712 can rotate synchronously with the hair dryer 100 or the handle 200 relative to the second control board 602 when the hair dryer 100 rotates relative to the handle 200, and the second electric ring 712 is used to be electrically connected to the high-voltage functional element of the hair dryer.

[0039] Specifically, the low-voltage functional element of the hair dryer may include a sensor device, which may include a displacement sensor and / or an infrared sensor. The displacement sensor is used to obtain the distance characteristic quantity between the hair dryer and the target object; the infrared sensor is used to obtain the temperature characteristic quantity of the target object, wherein the target object refers to the object being blown, conventionally hair, and may also be a related object for local drying, heating and physical therapy in laboratories, industrial production, art, etc.

[0040] The high-voltage functional elements of the hair dryer may include a heating component 300 and / or a blowing component 400. The heating component 300 is used to heat the flowing gas flowing through the air duct 130. The blowing component 400 is used to draw the flowing gas into the air duct 130 through the air inlet 120, and then the flowing gas flows out from the air outlet 110 after being heated or not heated by the heating component 300.

The routing length of the cable along the outer wall of the wiring ring 720 is greater than or equal to the maximum rotational displacement of the wiring ring 720 to rotate synchronously with the handle 200 or the hair dryer 100. Since the cable is routed along the rotation trajectory of the hair dryer 100 or the handle 200 with the aid of the routing ring 720, and the routing length of the cable along the outer wall of the routing ring 720 is long enough (specifically greater than or equal to the maximum rotational displacement of the routing ring 720 following the synchronous rotation of the handle 200 or the hair dryer 100), sufficient routing margin can be provided for the rotational movement between the handle 200 and the hair dryer 100, ensuring that the cable routed between the handle 200 and the hair dryer 100 will not break due to the large-scale rotation between the handle 200 and the hair dryer 100. In addition, the wiring through the routing ring 720 to connect the control panel 600 and the functional components of the hair dryer makes the wiring more organized, does not cause cable accumulation compared to traditional methods, makes the line more beautiful, and facilitates the maintenance of the line.

The second cable is connected to the second control board and is led out through the second wiring hole and routed along the outer wall of the second wiring ring, and then enters the handle 200 along the second wiring channel and is electrically connected to another functional element disposed in the handle 200. Specifically, the first cable is used to electrically connect the low-voltage functional element in the handle 200, and the second cable is used to electrically connect the high-voltage functional element in the handle 200.

[0051] In an optional embodiment, the handle 200 is connected to the wind tube 100 in a damped rotation connection. Since the handle 200 is connected to the wind tube 100 in a damped rotation connection, when the user rotates the handle 200 relative to the wind tube 100 to any angle, the handle 200 and the wind tube 100 can maintain the angle under the action of the damping force generated by the damped rotation, thereby achieving arbitrary adjustment of the opening angle between the handle 200 and the wind tube 100.
