In the coaxial and upright state of the working head 1 and the handle 2, the outer surface of the first part 341 and the outer surface of the second part 342 are substantially coplanar, so that the exposed part of the locking mechanism 34 has a flat appearance.

[0049] Further, the side end surface of the first part 341 is provided with a locking portion 3411, and the second bracket 344 is provided with a locking matching portion 3441, and the locking portion 3411 and the locking matching portion 3441 are used to fix the first part 341 and the second part 342 after rotating a predetermined angle. That is, the working head 1 and the handle 2 are maintained in the coaxial and upright state and the bending and rotating state through the locking portion 3411 and the locking matching portion 3441, so as to maintain the straight or bending working state.

[0054] Considering that there is a certain gap at the joint of the handle shell 21 and the head shell 11 in the coaxial upright state of the working head 1 and the handle 2, a magnet auxiliary positioning member 345 is used to eliminate or reduce the gap. Specifically, the locking mechanism 34 further comprises a magnet auxiliary positioning member 345, which is arranged on the outer wall of the handle shell 21 on the other side relative to the second bracket 344, and the magnet auxiliary positioning member 345 can extend to the outer wall of the head shell 11 and can be magnetically attracted to the outer wall end of the head shell 11. That is, in the coaxial upright state of the working head 1 and the handle 2, the magnet auxiliary positioning member 345 and the second bracket 344 are located on the two sides of the axis of the handle head symmetrically.

[0055] In the embodiment, the working head 1 has an air outlet 12 for air blowing; the handle 2 is held by an operator; the bending connection structure 3 is connected between the working head 1 and the handle 2, and can switch the working head 1 relative to the handle 2 between a coaxial upright state and a bending state.

[0058] For example, the flexible pipe 31 has an inner pipe 311 and can also have an outer pipe 312, both the inner pipe 311 and the outer pipe 312 are flexible and stretchable, and optionally, the inner pipe 311 is a spring pipe; if the outer pipe 312 is provided, the outer pipe 312 is sleeved outside the inner pipe 311, and the outer pipe 312 is an elastic decorative member and plays a decorative and protective role. Optionally, the two ends of the inner pipe 311 and the outer pipe 312 are fixed through gluing or in-mold injection with the first fixing member 32 and the second fixing member 33. When the bending angle is specified, the spring pipe and the external elastic decorative pipe are in a stretched state, realizing the bending of the air duct.

[0059] In the embodiment, the head shell 11 is provided with a sleeve 14, and the sleeve 14 is provided with a heating wire 15, which can heat the air passing through the first air duct.

When the user uses it to blow hair, the working head 1 can be bent to present 90 degrees or other suitable angles with the handle for use. When the user uses it to make hair curling, the working head 1 can be straightened to present coaxial and upright state with the handle part 2, which is convenient for operation of hair curling. Of course, the user can choose a comfortable angle to use the hair care appliance to blow hair in upright state or to curl hair in bent state, so as to meet different use habits of the user, and the user can choose a comfortable angle to use the hair care appliance.
