[0030] like Figures 1 to 3 As shown, the present application provides a hair dryer, which includes a hair dryer 100 and a handle 200. The handle 200 is rotatably connected to one end of the hair dryer 100 to unfold or fold the hair dryer. An air outlet 110 is provided at one end of the hair dryer 100, and an air inlet 120 is provided on the other end of the hair dryer 100 and / or the end of the handle 200 connected to the hair dryer 100. The air inlet 120 is connected to the air outlet 110 to form an air duct 130, and when the opening angle between the handle 200 and the hair dryer 100 reaches a preset value, the unfolded hair dryer can be supported on the operating platform without the help of external force.

[0031] When using the hair dryer provided by the present application, 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. In addition, when the opening angle between the handle 200 and the hair dryer 100 reaches a preset value, the unfolded hair dryer can be directly supported on an operating platform (such as a desktop) without the aid of external force, so that the hair dryer can be completely free from the hands when in use, and the user can free up both hands to better perform other operations; after use, the user holds the hair dryer 100 and the handle 200 with both hands respectively and rotates them together to fold them to save space and facilitate travel, etc. The reliability when in use and the foldability when not in use reflect the advantage of the compact structure of the hair dryer.

[0032] In an optional embodiment, the handle 200 is connected to the hair dryer 100 in a damped rotation connection. Due to the damped rotation connection, when the user rotates the handle 200 relative to the hair dryer 100 to any angle, the handle 200 and the hair dryer 100 can maintain the angle due to the damping force generated by the damped rotation, thereby achieving stepless adjustment of the opening angle between the handle 200 and the hair dryer 100.

[0033] In an optional embodiment, the opening angle between the handle 200 and the hair dryer 100 (i.e., the rotation angle of the handle 200 relative to the hair dryer 100) is 0 to 210 degrees. It should be noted that when the handle 200 and the hair dryer 100 are completely folded and retracted, the handle 200 and the hair dryer 100 are parallel to each other. In this state, the opening angle between the handle 200 and the hair dryer 100 is 0 degrees.

[0034] like Figure 4 As shown, further, a positioning ring 140 is provided between the handle 200 and the hair dryer 100, and the positioning ring 140 is used to limit the rotation of the handle 200 relative to the hair dryer 100, thereby preventing the hair dryer from abnormally folding or excessively rotating due to excessive external force used by the user.
