The utility model relates to an electric heating curling iron. It includes a curling body, an electric heating body, a handle and a wire. The curling body, handle and other structures are improved in this hair curler. At the same time, a thermal insulation cover and a pressing sheet are provided so that the hair does not directly contact the curling body, which protects the hair and improves safety, it has the characteristics of simple structure, convenient use, and suitable for family use.
An electric hair curling iron, comprising a curling body with a circular cross-section and an electric heating core in it,The handle and wire are characterized in that a raised boss is designed on the upper part of the curling body with a circular cross-section, and an insulating sleeve with a certain gap is arranged on the outside of the curling body. There is a long narrow groove on the upper part of the insulating sleeve to make the curling body The convex protrusion of the upper protrusion is just stuck in the long narrow groove. At the same time, a semi-circular pressing piece is arranged on the long narrow groove of the insulating sleeve and under the handle. The center of the pressing piece is circular and can be fitted on the handle. It is connected by a small shaft, and a spring sheet is arranged under the joint of the pressing piece, which can make the boss on the hair curling body move downward relative to the heat insulating sleeve so that the boss does not expose the surface of the heat insulating sleeve.
The utility model belongs to an electric heating curling device or tool
At present, there are many types of devices or tools in the curling and perm industries, such as devices or tools that use heat or medicine to curl the hair. The electric hair curling comb sold on the market is relatively close to the existing technology. It consists of a metal comb, an electric heater inside, an insulated handle, etc., because when the comb is used, the metal comb (usually aluminum and its alloy) directly touches the hair , It is easy to scorch the hair, which is not safe, and the metal aluminum is harmful to the human body, thus affecting its promotion and application. In response to the above situation, the new model has developed an electric hair curler with simple structure, convenient use, safe and reliable, and suitable for household use.
It is realized by the following way: an electric hair curling device, comprising a round cross-section hair curling body and an electric heating core, handle and wires in it, characterized in that a convex boss is designed on the upper part of the round cross-section curling body, and A thermal insulation sleeve with a certain gap is arranged on the outside of the curling body. There is a long narrow groove on the upper part of the thermal insulation sleeve, so that the convex protrusion on the curling body is just stuck in the long narrow groove. A circular pressing piece is arranged on the top of the Jubilee and under the handle. The center of the pressing piece is circular and can be set on the handle and hinged with a small shaft. A spring piece is arranged under the hinge of the pressing piece, which can make the heat insulating sleeve move up and curl the hair. The protrusion on the body moves down relatively, so that the protrusion does not expose the surface of the insulating sleeve.
When it is in use, first turn on the power, the electric heating core first heats and heats the curling body, and it can reach the working temperature in about one minute. The pressing sheet at the curling body is opened), and a bunch of hair to be curled is placed on the projection of the pressing sheet and the curling body. At this time, the thermal insulation sleeve is bounced under the action of the spring sheet, and the projection on the curling body moves down relatively , The boss on the curling body does not expose the surface of the insulating sleeve, which can prevent the hair from directly contacting the curling body, prevent hair damage, improve safety and reliability, and hold the pressing plate at the handle so that the pressing plate at the curling body clamps the hair into work State (see Figure 2), at the same time, pull up the curling iron in the direction of the arrow in Figure 2. At this time, the thermal insulation sleeve is pressed down, and the protrusions on the curling body are exposed. The hair slides continuously on the curling body, and the side of the hair contacting the curling body is heated by the shrinking body. The hair is bent, and the heat insulation cover protects the other parts of the hair from high temperature. Between sets) cooling and styling. When the hair leaves the electric curling iron, the temperature is low enough and its internal stress no longer changes. At this time, a bunch of hair curling is completed. After all the hair to be curled with this method, the curling is completed.
Compared with the prior art, the utility model has the characteristics of simple structure, convenient use, safe and reliable, suitable for family use, etc.
