Detailed description

The utility model provides a hair curling iron. 1 and 2, in the embodiment of the present invention, the hair curling iron 100 includes: a handle 110; a heating body 160, the heating body is cylindrical, and one end of the heating body 160 is connected to the handle 110;

A first clamping area is formed on the outer surface of the heating body;

The hair clipping mechanism 120 is movably connected to the handle 110 to open or close relative to the heating body 160. The outer surface of the hair clipping mechanism 120 is formed with a second clamping area. When the hair clipping mechanism 120 is closed to the heating body, the first clamping area and the second clamping area are disposed opposite to each other for clamping hair.

The handle 110 of the present invention is cylindrical, and the upper cover and the lower cover are fixed by screws to form an internal cavity. The cavity is provided with a PCBA circuit board and components that provide power for the heating body 160. The end of the handle 110 is provided with The power cord is used to connect the external power supply. The heating body needs to be electrically connected to the circuit board, so the heating body 160 can be connected to the handle 110 and the circuit board through a wire or a conduit to realize power supply to the heating body. The heating body is cylindrical and has a hollow design. It is convenient to rotate and curl the hair, and the weight is light, and it will not be too tired when hand-held. The cylindrical shape can be understood as a cylindrical shape, or it can be a square cylindrical shape or a hollow hexagonal structure. The first clamping area, the first clamping area is directly in contact with the hair, and the head can be heated. Different from the existing heat transfer method, the heating body does not need to pass the heat through the heating body and then conduct the heat.

To the outer shell of the curling iron, the outer shell is heated and the hair is curled, so the repeated heat transfer will not only cause the heat transfer efficiency to be slow, but also cause a large amount of heat loss and waste.

Of course, in order to ensure that the current will not be conducted to the hair during use, the first clamping area needs to be an insulating heat conductor. At the same time, since the hair is wrapped around the surface of the heating body 160, the first clamping area is set on the outer surface of the heating body, and the heating body is It can be a metal heating element or a non-metal heating element, such as a stainless steel heating element, a silicon carbon rod heating element, a glass heating element, etc., and it mainly has the function of electrical conduction and heat transfer. In addition, the heating body needs to rely on the hair clipping mechanism 120 to fix the tail of the hair on the heating body when curling the hair, so that the heating body rotates to wrap the hair around the heating body to achieve the curling of the hair. The hair clipping mechanism 120 and The heating body is movably connected and can be opened and closed relative to the heating body. In the non-working state of the hair curler, the hair clipping mechanism 120 is in a closed state relative to the heating body 160. When working, the hair clipping mechanism 120 is opened, and the hair is placed on the hair clipping mechanism 120 and the heating body. At the same time, the hair clipping mechanism 120 is closed and clamped, and the hair is clamped on the heating body. The opening and closing of the hair clipping mechanism 120 can be realized by manual manual pressing and loosening, or a control switch can be set to control the hair through intelligent control. The switch enables opening and closing of the hair clip mechanism 120 .

Understandably, in the present invention, a heating body is arranged at one end of the handle 110, and the heating body is cylindrical, and the hair is wound on the cylindrical heating body 160, so that the heat emitted by the heating body is conducted to the hair. The curling of the hair also cooperates with the hair clipping mechanism 120. The hair clipping mechanism 120 can be opened and closed on the top of the heating body to act on the heating body and clamp the hair. When the heating body is in contact with the hair, it has a first clamping area. The hair-clamping mechanism 120 has a second clamping area when it is in contact with the hair. When the hair-clamping mechanism 120 is opened and closed, it can be relatively far away from or close to the heating body. When the first clamping area and the second clamping area are in relative positions, that is, clamping. The mechanism is close to and closed to the heating body 160 to achieve clamping and curling of the hair. By energizing the heating body, the utility model heats the heating body and the first clamping area of ​​the heating body and conducts the heat to the hair, so as to realize the heating and curling treatment of the hair, and directly heat the hair through the heating body 160. The heat conduction method (the heat is conducted to the heating body through the heating body, and then the heat is conducted to the heating rod shell through the heating body, and finally the hair is heated through the heating rod shell), this conduction method has a simple structure, fast heat conduction, and reduces conduction energy loss in the process. That is, the improvement of the heat conduction mode of the heating body is realized, and the heat conduction rate of the heating body is improved.

In this embodiment, the outer surface of the heating body is covered with a thermally conductive layer.

The heat-conducting layer is arranged on the outer surface of the heating body for heat conduction. The heating body 160 is in contact with the hair through the heat-conducting layer, and the heat-conducting layer directly contacts the hair to conduct the heat of the heating body to the hair. Therefore, the heat-conducting layer needs to have the function of insulating and heat-conducting, so the heating body and the hair are in contact with the hair. The connection methods and materials of the heat-conducting layer can be selected in various ways. The heat-conducting layer can be made of ceramic parts or glass parts, which can be painted or laid on the contact surface of the heating element and the hair. When the heating element 130 is heated, the heat is conducted to the ceramic or glass parts. , so that the ceramic piece or glass piece heats the hair, or the top of the ceramic piece or glass piece can abut on the contact area between the heating body and the hair. One way, that is, the heat-conducting layer is made of glass, and the glass (heat-conducting layer) is applied to the contact area between the heating body and the hair (the first clamping area). The layer conducts heat to the hair, thereby achieving heating of the hair.

In this embodiment, the thermally conductive layer is an insulating thermally conductive layer.

Understandably, since the heat-conducting layer should be able to conduct both the heat emitted by the heating body 160 and the received heat to the hair, and the human body is an electrical conductor, the hair only needs to receive heat and cannot conduct the power to the human body, that is, heat conduction. The layer needs to be thermally conductive and an insulator, so the thermally conductive layer can be a glass piece or a ceramic piece.

In this embodiment, the hair curler further includes a bracket 130 , the bracket 130 is cylindrical, one end of the bracket 130 is connected to the handle 110 , and the heating element 160 is sleeved on the bracket 130 .

The bracket 130 is connected to the handle 110 for supporting the heating element. The heating element 160 is sleeved on the outside of the bracket 130 to ensure the stability of the heating element. Therefore, the structure of the bracket 130 is similar to that of the heating element and is cylindrical. The bracket 130 and the handle 110 The connection between the bracket 130 and the handle 110 is provided with a through hole. The screw passes through the through hole and is at least partially inserted into the handle 110 to fix the bracket 130. The overall structure of the bracket 130 is similar to that of the heating body, and the bracket 130 is made of metal. The bracket 130 is arranged to carry the heating body and is connected to the handle 110 through the bracket 130, which can prevent the handle 110 from directly contacting the heating body.

In this embodiment, the heating body 160 has a cylindrical structure.

Since the hair is wrapped around the outer surface of the heating body 160, the heat is conducted to the hair through the heating body 160 to realize the heating of the hair. At the same time, when the hair is too long, the heating body needs to be rotated so that all the hairs are wrapped around the outer surface of the heating body, so the heating body 160 is set in a cylindrical shape, which can make the hair wrapped around the heating body heat more evenly, but the curl is more balanced.
