PTC Ceramic Heating Curling Iron

18 2021.12.10

A curling iron used to beautify hair in daily life. The original technology of the hair roller assembly is electrically heated, which is unsafe in use, and there are not many heating rollers. The utility model is composed of a middle cradle fixed on a bottom frame, an electric heating tube, a hair roller, and a hair clipper. A temperature relay is provided to control the temperature. The electric heating tube is composed of a metal shell, an insulator and an electric heating wire. The curling roller is composed of a plastic shell and a metal heat-conducting sleeve. The curling device is a cylinder made of plastic. After the curling curler rises to an appropriate temperature, remove the curled hair and clamp it with the curling device. The hair is not easy to loosen and can be heated at one time. 6-25 curling rollers.

1. A hair curler, which is composed of a box consisting of an upper cover and a bottom frame, a middle frame, an electric heating tube, a curling tube, and a hair clipper. It is characterized in that: the electric heating tubes on the middle frame are connected in series, and there is a temperature breaker in the circuit. The entire middle frame is placed in the box; the electric heating tube is a cylindrical shell made of metal aluminum, with an insulator and the resistance wire wrapped in the shell, the U-shaped resistance wire is supported on the support plate, and the electric heating tube is in a closed shape The hair roller is made of plastic and has a cylindrical shape with a certain thickness, with comb-shaped teeth on the outside and a heat-conducting cylinder made of metal on the inner wall; the hair clipper is made of plastic in a cylindrical shape, and the barrel is a stringer structure.

2. The hair curler according to claim 1, characterized in that the hair clipper is made of plastic in a cylindrical shape, and the cylinder has a stringer structure.

3. The hair curler according to claim 1, characterized in that the heating wire in the electric heating tube is wrapped in an aluminum sleeve by an insulator.

4. The hair curler according to claim 1, characterized in that: 6-25 heating tubes can be installed on one middle frame.

5. The hair curler according to claim 1, characterized in that the metal heat-conducting sleeve of the curling barrel is embedded in the heat-insulating plastic barrel with comb-shaped teeth.

6. The hair curler according to claim 1, characterized in that: the middle frame, the heat generating tube, the curling barrel, and the hair clip are placed in a box composed of a bottom frame and an upper cover.

7. The hair curler according to claim 1, characterized in that there is a temperature breaker in the line of the middle frame.

The disadvantage of the prior art lies in the fact that the hair roller assembly is charged during the heating process of the hair curler. Although separated by insulating materials, it is easy to cause unsafe accidents. Its heating element is a circular PTC ceramic heating element on a cross section perpendicular to the cylinder axis. Therefore, when heating, conduct heat conduction from the upper and lower ends of the middle section. The heating efficiency is not high, time-consuming, and uneven heating. The electrical interface of the curling barrel and the box base must be aligned when the power is turned on, which brings inconvenience to the operation. There is only a comb outside the curling barrel. Shaped teeth, it is not easy to fix the hair, the curling barrel adopts PTC ceramic heating element, and there is a plug-in interface inside, so the curling barrel is heavier and the processing is complicated and the cost is high.

The purpose of the utility model is to change the heating principle of the hair roller on the basis of the prior art, and add a hair clipper outside the comb-tooth hair roller, so that the hair roller can better fix the hair.

The technical scheme of the utility model is: a rectangular box woven by an openable upper cover and a bottom frame, and a middle frame, an electric heating tube, a hair roller, a hair clipper, a temperature relay, etc., which are installed in the bottom frame. The electric heating tube is installed on the middle frame (the middle frames of the upper and lower covers are made of plastic). The electric heating tube is made of aluminum alloy, an insulator made of insulating material is arranged in the middle of the thin cylindrical shell, and the heating wire is placed in the insulator, so that the aluminum shell is not charged. The entire heating tube is in a closed shape, and the two ends of the heating wire are drawn out of the tube to be connected to the junction seat of the middle frame with heat insulation treatment. The hair roller is made into a cylindrical shape, and one end is closed, so that it can be conveniently placed on the electric heating tube. There are comb-shaped teeth on the outside, which are made of plastic, and the inner wall of the cylinder is provided with an aluminum metal heat-conducting sleeve. The cylinder has a certain thickness for heat preservation. The curling roller is sheathed on the electric heating tube to heat up. There is a hair clipper outside the curling barrel, which is a cylindrical shape made of plastic, and the barrel has a stringer structure. When in use, it is inserted into the heat-preserving curling barrel from the opening of the cylinder to clamp the hair. Several electric heating tubes can be arranged on the middle frame. In order to make the curling iron cut off power after reaching a predetermined temperature, a temperature relay is installed in the circuit of the middle frame.

The utility model is characterized in that there are several electric heating tubes on the middle frame, a temperature relay on the circuit, and the electric heating tubes are made of aluminum alloy into a cylindrical shell, and there is a layer of insulator wrapped on the heating wire, and the shell of the hair roller It is made of plastic and has comb-shaped teeth. There is an aluminum thermal sleeve inside. The hair curler is covered with a hair clipper. The structure is simplified as a stringer structure. The curlers and the middle frame are placed by the bottom frame and In a box composed of an upper cover.

The present utility model is further described in detail below in conjunction with the embodiments:

6-25 electric heating tubes (1) of varying sizes are arranged on the middle frame (2) made of plastic, and each heating tube (1) is connected in series, and on the line It is connected with a commercially available temperature relay, when the electric heating tube (1) is energized and heated to the set temperature, the power will be automatically cut off. Electric heating tube (1) by A cylindrical jacket (6) made of metal aluminum is shown in Figure 2. The jacket (6) has an insulating ceramic tube (7) as an insulator, and the center of the ceramic tube (7) has a support plate (8) made of mica, U Type resistance wire(9) Just supported on the mica sheet, there are leads (10) to lead out the electric heating tube body, the whole heating tube (1) is closed, and the top of the ceramic tube (7) is also insulated with mica and aluminum sleeve (6). Therefore, after energization, the resistance wire (9) generates heat and conducts to the ceramic tube (7) and the metal aluminum shell (6), so that the hair roller (3) sheathed on the electric heating tube (1) has a certain temperature, and the hair is curled. The barrel (3) is made of heat-resistant plastic and the shell (11) has a certain thickness to keep it warm. The curly hair slip (3) has a heat-conducting sleeve (12) made of metal aluminum on the inner wall, and comb-shaped teeth are arranged on the outer shell. The hair clipper (4) is made of plastic and has a cylindrical shape (as shown in Figure 3). The entire middle frame (2) is equipped with a heating tube (1), a curling tube (3), and a hair clipper (4). In a box (6) made of plastic.

Compared with the prior art, the utility model has the advantages of safety, reliability, simple manufacture, low cost, and curly hair that is not easy to loosen.
