DETAILED DESCRIPTION

The disclosure will be further described below in conjunction with accompanying drawings:

Referring to FIGS. 1-4, a curling device according to an embodiment is shown. The curling device includes a curling component 1 and a handle component 2, wherein the curling component 1 includes two clamping parts 11 arranged oppositely and a sleeve 12 concentrically sleeved on the clamping parts 11. The handle component 2 includes a housing 21, a driving motor 22 disposed within the housing 21 and used for driving the clamping parts 11 or the sleeve 12 to rotate around an axis, and an airflow generating component 23 for providing cold wind. The sleeve 12 has a placement groove 121 for receiving hair which extends axially and being open outwards. The clamping part 11 comprises a shell 111 extending axially and having an axial mounting groove 111a inwards, a heating plate component 113 mounted in the mounting groove 111a by one or more springs 112, and a metal plate 114 fixed on the back surface of the shell 111 and being arc-shaped viewed in cross section. Two sets of opposite heating plate components 113 are capable of being in contact with each other by the springs 112 to provide a perm working surface 11a. A cooling channel provided between the back surface of the shell 111 and the metal plate 114 is in fluid communication with the handle component 2. One or more air holes 115 are provided on the metal plate 114, and the metal plate 114 has a smooth layer such that a cylindrical and smooth curl cooling surface 11b is formed by two opposite metal plates 114. A control circuit board 24 is arranged within the housing 21 of the handle component 2, and an air inlet 25 is provided at the end of the housing 21 away from the curling component 1 (or its trailing end). The airflow generating component 23 comprises a motor and fan blades for generating cold wind blowing to the curling component 1. The heating plate component 113 comprises a heating plate with a receptacle, and a heating element and a temperature control sensor installed in the receptacle.

When curling hair, a bundle of hair may be positioned between the perm working surfaces 11a, and then a continuous rotation is executed so that the hair is completely wrapped around the outer peripheral surface of the clamping parts 11, in this way, the hair is combed slowly towards the end. During the combing process, the hair is heated by the perm working surfaces 11a and cooled by the curl cooling surfaces 11b, which facilitates curling and styles the hair quickly.

The hair clamped by the perm working surfaces 11a is then fully wrapped around the curl cooling surfaces 11b after the rotation, which tends to cause hair to be stuck or impede combing action. If it is partially wrapped around the cooling surface, e.g. only half or one turn at a time depending on the control of a button, this is not conducive to the curling performance because the length of curled hair is too short during the perming process. Moreover, this controlled rotation leads to a complicated operation, for example, when the hair is wrapped too tightly, it is necessary to reverse the rotation via the button to loosen the hair, and in some embodiments, the rotation caused by multiple operations of the button will make the hair entangled too tightly, which leaves a risk. The smooth layer provided on the outer peripheral surface of the metal plate 114 enables the curl cooling surface 11b to achieve a better cooling effect, while solving the problem that the hair gets stuck because of continuous rotation and winding so that the hair can be easily combed. This designs a simple curling device and its control method, and a better curling effect can be obtained.

In a preferable embodiment, the metal plate 114 has arc-shaped edges 114a open inwards at its two longer sides, and the heating plate component 113 has arc-shaped edges 113a at its two longer sides corresponding to the perm working surface 11a, in this way, a smooth transition surface 11c is formed at the junction of the perm working surface 11a and the cooling surface 11b. Furthermore, the smooth layer on the outer peripheral surface of the metal plate 114 is selected as one of an oxide layer, a paint layer or an electroplating layer. As a small angle is formed between the perm working surface 11a and the curl cooling surface 11b, the smooth transition surface 11c is used to reduce the frictional resistance of the hair, which makes combing more labor-saving and avoids hair damage or snap off caused by excessive curling.

In a preferable embodiment, a flared guiding surface 11d for guiding hair is provided at the outward end of the perm working surface 11a, and a flared guiding portion 122 corresponding to the guiding surface 11d is provided at the outward end of the sleeve 12. The guiding surface 11d and the guiding portion 122 can easily snap the hair between the perm working surfaces 11a.

In a preferable embodiment, the placement groove 121 of the sleeve 12 is a groove having a width that gradually decreases towards its outer end (or away from the handle component 2), which prevents hair from escaping from the outer end during the rotation process.

The above description does not intend to limit the technical scope of the present disclosure. Any modifications, equivalent changes and modifications made to the above embodiments according to the concept of the present disclosure still fall within the scope of the technical solution of the present disclosure.
