[0002] A hair straightener is a hairdressing tool that combines the functions of hair drying and hair straightening. Its feature is that it can blow out airflow to dry hair like an ordinary hair dryer, and can also use the clamping plate to straighten hair. This makes it more convenient and quick to use, and you can do hair straightening while drying your hair, saving time. The heating frame of a hair straightener usually uses a heating wire wrapped around a mica support sheet. The common heating frame is small in size and cannot be installed with a fuse. When the current rises rapidly, the circuit cannot be protected, which poses certain safety hazards. Summary of the invention

[0005] By adopting the above technical solution, the heating element is protected by the fuse. When the temperature of the heating element is too high or the current is excessive, the fuse disconnects the circuit to protect the heating element, thereby protecting the circuit and extending the practical life of the hair straightener.

[0006] The protection provided by the safety circuit can effectively prevent the heating wire from overheating, making the hair straightener safer to use.

[0007] Optionally, a placement platform for placing the safety component is fixed on the first support platform; connecting rings are installed at both ends of the safety component; screw holes are opened on the upper side of the placement platform; and the safety component is locked on the placement platform by screws.

[0008] By adopting the above technical solution, a placement table specially used for preventing the safety member is installed on the first supporting table, and the safety member is installed on the placement table, so that the volume of the heating rack does not need to be increased to install the safety member.

[0009] The safety piece is fixed on the placement table by bolts passing through the connecting ring, making the installation of the safety piece more convenient and quick

[0010] Optionally, the safety component is a fuse tube.

[0011] By adopting the above technical solution, when the current increases or the temperature rises, the fuse of the fuse tube blows, which can disconnect the circuit in a short time, protect the hair straightener, and prevent the high temperature from causing harm to the user.

[0012] Optionally, the safety component is a temperature sensor.

[0013] By adopting the above technical solution, the temperature sensor is used to quickly cut off the circuit when the temperature rises, thereby protecting the hair straightener and preventing the high temperature from causing harm to the user.

[0014] Optionally, the heating component includes a first support frame, a second support frame and a heating wire installed on the first support frame and the second support frame; one end of the first support frame is connected to the first support platform, and the other end is connected to the second support platform; one end of the second support frame is connected to the placement platform, and the other end is connected to the second support platform.

[0016] Optionally, the first support frame and the second support frame are both a pair of mica sheets parallel to each other; limiting grooves for limiting the heating wire are opened on both sides of the mica sheets.

[0017] By adopting the above technical solution, the heating wires can be evenly distributed on the mica sheet through the limiting grooves.

[0018] Optionally, the mica sheet is provided with elongated holes, and the elongated holes are used for heat dissipation.

[0019] By adopting the above technical solution, the gas can flow through the long holes in the middle of the mica sheet through the long holes, thereby increasing the heat dissipation effect.

[0021] By adopting the above technical solution, under the action of the dividing protrusion, a sufficient gap is left between the first support frame and the second support frame after installation, which can effectively prevent the heating wires from overlapping each other, causing the local temperature to be too high and burn out the heating wires;

[0022] At the same time, air can pass through the gap between the first support frame and the second support frame to accelerate heat dissipation.

[0023] Optionally, the heating component includes support plates installed in parallel on the upper and lower sides of the first support platform and the second support platform; a heating wire is wound on the support plates; the safety component is installed between the support plates; and the safety component is connected in series with the heating wire through a metal sheet.

[0024] By adopting the above technical solution, the support sheets are installed on the upper and lower sides of the first support platform and the second support platform, so that the internal space of the heating wire can be increased, and the safety element can be installed between the support sheets;

[0025] The safety component is connected in series with the heating wire through a metal sheet to reduce wind resistance.

[0026] Optionally, there may be multiple safety elements.

[0027] By adopting the above technical solution, multiple fuses can be connected in series in the circuit to improve the safety factor; at the same time, the temperature sensor can also be used together with the fuse tube to improve the safety factor.

[0030] The protection provided by the safety circuit can effectively prevent the heating wire from overheating, making the hair straightener safer to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Reference Figure 1 , Figure 2 A placement platform 5 for placing a safety element 4 is fixed on one side of the first support platform 1 close to the second support platform 2; connecting rings 41 are fixedly installed at both ends of the safety element 4; screw holes 51 are opened on the upper side of the placement platform 5; the safety element 4 is locked on the placement platform 5 by screws, and the heating component 3 is connected to the placement platform 5 at the same time; the safety element 4 can be quickly installed and removed through the connecting ring 41, and the safety element 4 can be quickly replaced when it is damaged; under the action of the placement platform 5, the safety element 4 can be installed without increasing the volume of the hair straightener heating frame, so as to improve the safety performance of the hair straightener.

[0041] Preferably, the safety element 4 is a fuse tube, which can quickly melt the fuse inside the fuse tube to disconnect the circuit when encountering a strong current, thereby protecting the hair straightener and effectively preventing the heating component from causing harm to the user due to instantaneous excessive temperature.

[0042] Preferably, the safety element 4 is a temperature sensor; when the temperature of the heating component 3 rises, the temperature sensor 4 senses the temperature rise and controls the switch (not shown) of the hair dryer to disconnect the power supply, so as to protect the hair dryer and prevent the hot air from being too hot and causing harm to the user.

[0043] Reference Figure 1 , Figure 4The heating component 3 includes a first support frame 31, a second support frame 32 and a heating wire 33 installed on the first support frame 31 and the second support frame 32; one end of the first support frame 31 is fixed to the first support platform 1 by bolts, and the other end is fixed to the second support platform 2 by bolts; one end of the second support frame 32 is fixed to the placement platform 5 by bolts, and the other end is fixed to the second support platform 2 by bolts. The heating wire is evenly wound on the first support frame 31 and the second support frame 32. The length of the second support frame 32 plus the length of the placement platform 5 is equal to the length of the first support frame 31, so that the safety component 4 is added without increasing the volume of the hair dryer straightener heating frame to protect the hair dryer straightener circuit and improve the safety factor.

[0044] Reference Figure 4 , Figure 5 The first support frame 31 and the second support frame 32 are both a pair of mica sheets 34 parallel to each other; a plurality of limiting grooves 35 for limiting the heating wire 33 are equidistantly provided on both sides of the mica sheet 34; by winding the heating wire 33 in the limiting groove 35, the heating wire 33 is evenly arranged on the first support frame 31 and the second support frame 32, so that the blown air is heated more evenly, and at the same time, it is effectively prevented that the local heating wires are too dense and the local temperature of the heating component is too high, which poses a safety hazard to the user.

[0045] Preferably, the mica sheet 34 is provided with long holes 36 ; the long holes 36 are used for heat dissipation; the wind can flow through the long holes 36 , thereby accelerating the heat dissipation of the heating component 3 and effectively preventing the temperature of the heating component 3 from rising sharply.

[0046] Reference Figure 1 , Figure 2 , Figure 3 A dividing protrusion 11 is fixed on the first support platform 1 and the second support platform 2; the first support frame 31 and the second support frame 32 are respectively installed on both sides of the dividing protrusion 11, so that a certain distance is maintained between the first support frame 31 and the second support frame 32, so as to prevent the heating wires 33 installed on the first support frame 31 and the second support frame 32 from interfering with each other and causing a sharp increase in temperature; at the same time, the hot air generated by the hair straightener can flow through the gap between the heating wires 33 on the first support frame 31 and the second support frame 32, so as to achieve uniform heating of the air; and the heat dissipation of the heating component 3 is accelerated again.

[0047] The second embodiment, referring to Figure 6 The heating component 3 includes support sheets 6 installed in parallel on the upper and lower sides of the first support platform 1 and the second support platform 2; a heating wire 33 is wound on the support sheet 6; a safety member 4 is installed between the support sheets 6; the safety member 4 is connected in series with the heating wire 33 through a metal sheet 7;

[0048] The support sheets 6 are respectively mounted on the upper and lower sides of the first support platform 1 and the second support platform 2, so that the space between the support sheets 6 is increased. There is enough space between the support sheets 6 for placing the safety element 4. The safety element 4 is connected in series with the heating wire 33 through the metal sheet 7. The direction of the metal sheet 7 is parallel to the support sheet 6, so that the wind can blow through the support sheets 6 to reduce the wind resistance.

[0049] Installing the safety member 4 between the support sheets 6 can make the safety member 4 be heated more evenly.

[0050] There can be multiple fuses 4, and multiple fuses can be connected in series in the circuit to improve the safety factor; the fuse tube and the temperature sensor can also be connected in series in the circuit at the same time to protect the circuit and improve the safety factor.
