[0031] The utility model provides a hair curler.
[0032] In the embodiment of the present utility model, Figures 1 to 3 As shown, the hair curler includes a main body 10, a movable arm 20, an electronic control device 30 and two ceramic heating plates 40. The main body 10 includes a gripping portion 11 and a mounting portion 12 connected to one end of the gripping portion 11; one end of the movable arm 20 is rotatably mounted on one end of the gripping portion 11 and is arranged opposite to the mounting portion 12; the electronic control device 30 is arranged on the gripping portion 11; each ceramic heating plate 40 is provided with a wiring portion at both ends to electrically connect to the electronic control device 30 through the wiring portion, one ceramic heating plate 40 is arranged on the movable arm 20, and the other ceramic heating plate 40 is arranged on the mounting portion 12. The two ceramic heating plates 40 are arranged opposite to each other to clamp the hair together.
[0033] That is, when in use, by holding the grip portion 11 with the thumb positioned on the pressing portion 21, the movable arm 20 can be rotated relative to the mounting portion 12 by pressing the pressing portion 21, thereby opening a certain space between the two ceramic heating plates 40. Optionally, a return spring 22 (torsion spring or compression spring) is provided between the movable arm 20 and the main body 10. The return spring 22 has elastic deformation that drives the movable arm 20 to rotate and return to the mounting portion 12.
[0034] In the embodiment, the electric control device 30 has a controller, a power supply circuit and the like circuit structure, and the specific circuit structure can refer to the prior art, and the utility model will not be described one by one. Optionally, the circuit device also has a power line 60, and the power line 60 is used for external power supply;Or the electric control device 30 has a power supply interface, and the power supply interface is used for connecting the power line 60.
[0035] The ceramic heating plate 40 is made of conductive ceramic material, and at least one terminal is arranged at each end of the ceramic heating plate 40. The terminals at both ends of the ceramic heating plate 40 are connected to the power supply circuit (the terminal at one end of the ceramic heating plate 40 is connected to the positive electrode of the power supply, and the terminal at the other end is connected to the negative electrode of the power supply). After the power supply is turned on, the current flows through the ceramic heating plate 40, thereby converting the electric energy into heat energy, so that the ceramic heating plate 40 generates heat.
[0036] The utility model technical scheme is through installing the ceramic heating plate 40 at the front end mounting portion 12 of the main body 10 and the movable arm 20 opposite to the mounting portion 12, after opening the movable arm 20 through the pressing portion 21, the ceramic heating plate 40 is directly contacted with the hair, so that the heat generated by the ceramic heating plate 40 can be quickly conducted to the surface thereof for contacting the hair. Compared with the traditional heating structure, the process of conducting heat from the heating device to the metal part is reduced, thereby reducing heat loss, quickly heating the surface of the ceramic heating plate 40 contacting the hair to the hair straightening temperature, significantly improving the heating speed of the hair iron during use, reducing the waiting time of the user from turning on the hair iron to use, and also helping to reduce power consumption, greatly facilitating the user.
[0037] In some embodiments, the ceramic heating plate 40 is a silicon carbide ceramic heating body. Specifically, the silicon carbide ceramic heating plate 40 is made of silicon carbide ceramic material, so that the silicon carbide ceramic heating plate 40 is a conductive structure and has a certain resistance, so that the silicon carbide ceramic heating plate 40 is a heating body as a whole. At least one terminal is arranged at each end of the silicon carbide ceramic heating plate 40. The terminals at both ends of the silicon carbide ceramic heating plate 40 are connected to the power supply circuit (the terminal at one end of the silicon carbide ceramic heating plate 40 is connected to the positive electrode of the power supply, and the terminal at the other end is connected to the negative electrode of the power supply). After the power supply is turned on, the current flows through the silicon carbide ceramic heating plate 40, thereby converting the electric energy into heat energy, so that the silicon carbide ceramic heating plate 40 generates heat. By using the silicon carbide ceramic heating body as the ceramic heating plate 40, the heating efficiency of the ceramic heating plate 40 can be improved, and the heating speed can be improved.
[0038] The silicon carbide ceramic heating plate 40 can be made by mixing silicon carbide powder as the main sintering phase raw material with one or more conductive phase raw materials selected from titanium nitride powder, zirconium nitride powder, titanium carbonitride powder, titanium carbide powder, zirconium carbide powder, thallium carbide powder, hafnium carbide powder, titanium boride powder, zirconium boride powder, molybdenum silicide powder, and tungsten carbide powder, and then forming and sintering the mixture according to the designed shape. For example, silicon carbide powder, yttrium oxide powder, aluminum oxide powder, and titanium boride powder can be uniformly mixed in a certain mass ratio, then water can be added as a solvent, uniformly mixed using a ball mill, and then spray-dried. The dried powder is heated and mixed with paraffin wax in a certain mass ratio, poured into a hot die casting machine, and hot die casting is completed. After the green body is dried, it is placed in a sintering furnace for sintering to obtain the silicon carbide ceramic heating plate 40. Of course, in other embodiments, zirconium oxide, aluminum oxide, yttrium oxide, silicon oxide, or silicon nitride can also be used as the main sintering phase raw material.
[0039] In some embodiments, the ceramic heating plate 40 includes a heating plate body and an insulating layer provided on the surface of the heating plate body. The heating plate body is mounted on the mounting portion 12 and is provided with a wiring portion. The insulating layer of each ceramic heating plate 40 is located on the side of its heating plate body facing the other ceramic heating element so as to contact the hair through the insulating layer. This can avoid the risk of short circuit when two ceramic heating plates 40 contact each other or when conductive devices are accidentally clamped, thereby improving safety in use. Of course, in other embodiments, when sintering the ceramic heating plate 40, the ceramic heating plate 40 can also be set as a multi-layer structure so that the resistance of the surface layer is greater than the resistance of the inner layer.
[0040] In some embodiments, the insulating layer and the heating plate are integrally sintered to improve the reliability of the insulating layer, reduce the risk of falling off, and improve thermal conductivity. During the molding process, a ceramic substrate can be formed first, and then an insulating ceramic slurry containing silicon dioxide is evenly coated on the surface of the ceramic substrate. The ceramic substrate coated with the insulating ceramic slurry is then placed in a high-temperature sintering furnace at 1000-12000°C for sintering, thereby obtaining a ceramic heating plate 40 with an insulating layer.
[0041] In some embodiments, both ends of the ceramic heating plate 40 are provided with a latching protrusion 41. The hair curler further includes two mounting bases 50, each of which is provided at each end of the ceramic heating plate 40 and has a socket 51 that plugs into the latching protrusion 41. That is, during installation, the two mounting bases 50 can be first installed at each end of the silicon carbide ceramic heating plate 40, so that the latching protrusions 41 snap into the corresponding sockets 51 of the mounting bases 50. The silicon carbide ceramic heating plate 40 and the two mounting bases 50 are then mounted on the mounting portion 12. After the mounting bases 50 are secured to the housing 13 of the main body 10 / movable arm 20, the silicon carbide ceramic heating plate 40 can be secured to the main body 10. This simple structure facilitates installation and helps reduce the production cost of the hair curler.
[0042] In some embodiments, the mutually facing surfaces of the two ceramic heating plates 40 are both flat. That is, the ceramic heating plates 40 are flat, which simplifies their structure and facilitates production. In other embodiments, one of the silicon carbide ceramic heating plates 40 has a concave curved surface, with its generatrix extending along the length of the body 10, while the other silicon carbide ceramic heating plate 40 has a convex curved surface that matches the concave curved surface, facilitating user shaping of hair texture.
[0043] In some embodiments, the hair iron further includes a battery and a charging component (not shown), both of which are electrically connected to the electronic control device 30, and the battery and the charging component are provided on the grip portion 11. In this way, the ceramic heating plate 40 can be powered by the battery, which is convenient for short-term use when going out. Moreover, when powered by a battery, the voltage used by the hair iron can be lower, and safety can be ensured even if an insulating layer is not provided on the ceramic heating plate. Among them, the charging component can be a charging port (such as a USB Type-C port) or a wireless charging coil.
[0044] In some embodiments, as Figure 4 and 5 As shown, the main body 10 includes a shell 13 and a cover 14. The shell 13 has a mounting portion 12 and a grip portion 11. The shell 13 is provided with a mounting opening 131 at one end away from the mounting portion 12. The mounting opening 131 is connected to the inner cavity of the shell 13. The cover 14 covers the mounting opening 131 and is provided with a wire hole 141. The hair curler also includes a power cord 60, which is passed through the wire hole 141 and is electrically connected to the electronic control device 30. That is, when installing the power cord 60, the power cord 60 can be first passed through the wire hole 141 and installed in the shell 13, and then the cover 14 is closed over the mounting opening 131. This facilitates the installation and maintenance of the power cord 60. Optionally, the electronic control device 30 has a step-down circuit, and the ceramic heating plate 40 is connected to the output end of the step-down circuit to reduce the output voltage of the ceramic heating plate 40 through the step-down circuit to improve safety.
[0045] In some embodiments, a mounting groove 132 is provided at the mounting port 131, the main body 10 also includes a limit cover 15, the power cord 60 includes a swivel assembly 61 and a wire 62 connected to the swivel assembly 61, the swivel assembly 61 is installed in the mounting groove 132, the limit cover 15 covers the side of the swivel assembly 61 away from the mounting groove 132, and is connected to the main body 10, so that the installation and maintenance of the swivel assembly 61 can be facilitated.
