Embodiment one.

Referring to Figures 1 to 4, a foldable hair dryer includes a casing, a heating mechanism 1, a blowing mechanism 2 and a control device 7, and the heating mechanism 1, blowing mechanism 2 and control device 7 are all arranged in the casing, so that The casing includes an air cylinder 3 and a handle 4, one end of the air cylinder 3 is an air outlet, the other end of the air cylinder 3 is provided with a first connector 5, and the upper end of the handle 4 is provided with a A connecting head 5 is hinged to a second connecting head 6 , and the first connecting head 5 or the second connecting head 6 is provided with a limiting protrusion 51 . When the hair dryer is in use, the user holds the hair dryer 3 and the handle 4 with both hands, and then pulls it to the limit protrusion 51 to open the folded hair dryer, and then operate it like a traditional hair dryer It should be emphasized that the first connecting head 5 and the second connecting head 6 can adopt a tight-fitting hinge connection structure, and the limiting protrusion 51 can be arranged on the first connecting head 5 or on the second connecting head 5. The connecting head 6 can realize the effect of the present technology; after use, the user can hold the blower 3 and the handle 4 with both hands to realize folding. The connection between the hair dryer 3 and the handle 4 of this hair dryer directly realizes the covered hinge, and at the same time, under the action of the limit protrusion 51, it can prevent abnormal folding or excessive rotation due to the external force used, and the use is quite reliable. , and when not in use, it can be folded directly to save space and facilitate travel and portability, etc. Obviously, the reliability in use and the foldable feature in use when not in use reflect the advantages of the compact structure of the hair dryer.

In this embodiment, the second connector 6 is hinged to the first connector 5 and is located outside the first connector 5, and both the second connector 6 and the first connector 5 are provided with air inlet holes 61 . That is to say, the second connector 6 of the handle 4 is covered on the outside of the first connector 5. Since the handle 4 is held by hand, the second connector 6 is arranged on the outside of the first connector 5 to provide Better supporting force, when working, under the effect of the blowing mechanism 2, a large amount of air enters from the air inlet hole 61 and is sent into the air cylinder 3 to blow out.

In this technical solution, the first connecting head 5 includes a left rotating case 52 and a right rotating case 53 that cooperate with each other. The hinge portion 533 connecting the support bar 532 with the shell body 531 is described.
