[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0036] As shown in Figures 1 to 8, this utility model embodiment provides a mica heater for a hair dryer, including an outer mica tube 1, an inner mica tube 2, a fixing bracket 3, a wound mica sheet 4, a heating wire 5, a fuse 6, a temperature controller 7, and a negative ion generator 8; the inner mica tube 2 is disposed inside the outer mica tube 1, and an accommodating space is formed between the inner mica tube 2 and the outer mica tube 1; the fixing bracket 3 is attached to the inner side of the inner mica tube 2, and the top of the fixing bracket 3 is provided with multiple spaced features along the circumferential direction. The clamping groove 30 is used to clamp and fix the wound mica sheet 4, which is located within the accommodating space. The double-layer structure of the inner mica tube 2 and the outer mica tube 1 can effectively prevent heat leakage. The multiple clamping grooves 30 on the top of the fixing bracket 3 can accurately clamp and fix the wound mica sheet 4, preventing it from shifting during use. In addition, the wound mica sheet 4 is located within the accommodating space and is isolated from the external environment, which can effectively reduce the interference of external airflow on the heating element, thereby improving the uniformity of the heating effect.
[0037] The heating wire 5 has a corrugated spiral structure. The outer wall of the winding mica sheet 4 is provided with a plurality of spaced winding grooves 40 along the vertical direction. The winding grooves 40 are used to fix and snap the heating wire 5. The corrugated spiral structure of the heating wire 5 can increase the surface area of the heating wire 5, thereby improving the heat conduction efficiency. The winding grooves 40 can accurately position the heating wire 5, preventing the heating wire 5 from shifting or loosening during use, thereby ensuring the stability of the heating effect.
[0038] One end of the heating wire 5 is connected to the first power line 101 via a first connecting piece 91, and the other end of the heating wire 5 is connected to one end of the fuse 6 via a second connecting piece 92. The other end of the fuse 6 is connected to one end of the thermostat 7 via a third connecting piece 93, and the other end of the thermostat 7 is connected to the second power line 102. The connection between one end of the heating wire 5 and the first power line 101 via the first connecting piece 91 allows electrical energy to be transferred to the heating wire 5 through the first power line 101, thereby achieving heating. The other end of the heating wire 5... One end of the fuse 6 is connected to the fuse 6 via the second connecting piece 92. When the current exceeds the safe value, the fuse 6 can automatically cut off the circuit, thereby preventing safety problems caused by current overload. The other end of the fuse 6 is connected to one end of the thermostat 7 via the third connecting piece 93. The thermostat 7 can control the heating process of the heating wire 5 to keep the temperature within a safe and suitable range. When the temperature is too high, the thermostat 7 can cut off the current, thereby preventing the heater from overheating. The other end of the thermostat 7 is connected via the second power line 102, thereby realizing the closed loop of the entire circuit.
[0039] An ion emission electrode 81 is provided between the fixed bracket 3 and the inner mica tube 2. The negative ion generator 8 is connected to the ion emission electrode 81 through a connecting wire 80. The negative ion generator 8 is used to deliver negative ions to the ion emission electrode 81. These negative ions are released into the airflow. The negative ions combine with water molecules in the airflow and penetrate into the hair through the airflow, thereby neutralizing the static electricity of the hair, reducing frizz, and making the hair smoother and softer.
[0040] As shown in Figure 2, it further includes an NTC sensor 100, which is located between two adjacent wound mica sheets 4. The NTC sensor 100 is used to detect the airflow temperature through the accommodating space. The temperature controller 7 can adjust the heating power according to the real-time temperature information provided by the NTC sensor 100, so that the heating temperature is maintained within the set range. This not only improves the temperature control accuracy of the hair dryer, but also enhances the safety of the heater.
[0041] As shown in Figure 7, the bottom of the ion emission electrode 81 is provided with a pointed needle portion 811 extending toward the accommodating space. This arrangement can improve the release efficiency of negative ions.
[0042] As shown in Figure 8, furthermore, the two ends of the temperature controller 7 are riveted to the top of the wire-wound mica sheet 4 by the first rivet 201. This arrangement can improve the assembly structure stability of the temperature controller 7.
[0043] As shown in Figure 6, furthermore, both ends of the fuse 6 are riveted to the bottom of the wire-wound mica sheet 4 by second rivets 202.
[0044] As shown in Figures 3 and 5, the fixed bracket 3 is provided with a first positioning groove 31 on the wall facing the inner mica tube 2, and the ion emission electrode 81 is located in the first positioning groove 31. This arrangement can improve the positioning accuracy and assembly stability of the ion emission electrode 81.
[0045] As shown in Figure 4, the winding groove 40 is further characterized by a triangular structure. Compared to other shapes, the triangular structure provides better clamping, thereby enhancing the installation stability of the heating wire 5.
[0046] As shown in Figures 2 and 5, the fixed bracket 3 is further provided with a second positioning groove 32 on the wall surface facing the inner mica tube 2. The second positioning groove 32 is used to position and constrain the sensor wire 1001 led out by the NTC sensor 100. This setting can effectively improve the assembly efficiency of the NTC sensor 100.
[0047] As shown in Figure 6, the first power line 101 and the second power line 102 are further riveted to the top of the wire-wound mica sheet 4 by the third rivet 203.
[0048] Furthermore, the diameter of the heating wire 5 is 0.3-0.6 mm. In this embodiment, the diameter of the heating wire 5 is 0.4 mm.
