[0061] Based on the embodiment 5, as shown in Figure 1 and Figure 3 , the elastic buckling member 400 has a plurality of elastic and tight buckling edges 41, which have the characteristics of plastic deformation and elastic deformation, so that the buckling edge 41 can be bent to form a structure close to a "concave" or "C" shape. The elastic buckling member 400 forms a buckling state by surrounding the first buckling part 311 and the second buckling part 321 after being bent by the plurality of buckling edges 41. In the buckling state, the elastic buckling member 400 continuously buckles the first clamping member 31 and the second clamping member 32, so that the distance between the first clamping member 31 and the second clamping member 32 continuously decreases until the first clamping member 31 and the second clamping member 32 are pressed on the conductive member 200 to contact the electrode layer of the conductive member 200 to limit the clamping distance.

In the loose buckling state, the first clamping member 31 and the second clamping member 32 no longer have the elastic clamping tightening force, and can be easily disassembled for maintenance, repair or replacement, which is convenient for users and workers to use.

[0062] Embodiment 7:

[0063] Based on the embodiment 6, as shown in Figure 1 and Figure 3The elastic buckle 400 has a buckle edge a, a buckle edge b, a buckle edge c and a buckle edge d. The buckle edge a is a first contact edge of the elastic buckle 400 for abutting against the first buckle part 311. The buckle edge b is a length extension edge of the elastic buckle 400 for enclosing the first buckle part 311 and the second buckle part 321. The buckle edge c is a second contact edge of the elastic buckle 400 for abutting against the second buckle part 321.

[0065] Embodiment 8:

[0066] Based on the embodiment 4, as shown in Figures 4-8 The conductive part 200 has a conductive wiring part 23 extending out of the outer side of the conductive part 200 in a direction away from the center of the conductive part 200 for connecting an external power source.

The clamping limiting part 34 has an avoiding opening 35 at a position corresponding to the conductive wiring part 23 for avoiding the conductive wiring part 23. The conductive wiring part 23 extends from the outer side of the conductive part 200 in a direction away from the center of the conductive part 200 and extends to the outside through the avoiding opening 35, which can be used for increasing the wiring range of the conductive part 200. On this basis, the conductive wiring part 23 is also provided with a threading hole for more conveniently installing the wiring later.

[0067] Embodiment 9:

[0068] Based on the above embodiments, as shown in Figure 6The heating component shown also includes a temperature control device 500 for detecting and controlling the heating temperature of the heating element. The temperature control device 500 is connected between the heating element and an external power supply. The temperature control device 500 can use an NTC thermistor to contact the surface of the substrate carrier 100 to detect its actual temperature, or use an infrared temperature probe to detect the actual temperature of the surface of the substrate carrier 100. The heating temperature of the substrate carrier 100 is monitored in real time through the temperature control device 500. The buttons on the temperature control device 500 can also be operated to manually adjust the preset temperature to avoid overheating and scalding the user. The temperature control device 500 is automatically adjusted in time according to the real-time heating temperature of the heating element so that the heating element reaches the preset temperature, thereby achieving the temperature control effect.

[0069] As another embodiment of Example 9, the temperature control device 500 can use a fuse as a temperature controller. When the current rises abnormally and exceeds the specified value, the heat generated by the temperature control device 500 causes the fuse to melt, thereby disconnecting the circuit. Since the temperature control device 500 is connected between the heating element and the external power supply, when the circuit is abnormal, the fuse can also be used as one of the power-off protection methods to prevent the heating temperature of the substrate carrier 100 from continuing to rise.

[0070] like Figures 1-8 As shown, the specific implementation of the utility model is as follows:

[0071] During the production, surface A and surface B are formed on the substrate carrier 100, and several parallel first through holes 12 are passed through surface A and surface B. The conductive heating layer adopts nano-semiconductor metal oxide and is attached to the surface of several first through holes 12 by physical vapor deposition (PVD). The electrode layer adopts silver paste and is laid on surface A and surface B respectively. The electrode layer of surface A and the electrode layer of surface B respectively contact the conductive heating layer from both ends of the first through hole 12 (can be connected in series or in parallel).

[0072] During installation, the conductive part 200 is sleeved on the substrate carrier 100, and the contact parts 24 of the two conductive parts 200 respectively contact the electrode layer of surface A and the electrode layer of surface B, and then the insulating clamping parts 300 are surrounded by the outer sides of the conductive part 200 and the substrate carrier 100 to form a structure clamped from the outside to the inside on both sides. The first clamping part 31 is sleeved on the conductive part 200 on the outside of surface A and is pressed against the surface of the conductive part 200 through the clamping ribs 36. The second clamping part 32 is sleeved on the conductive part 200 on the outside of surface B and is pressed against the surface of the conductive part 200 through the clamping ribs 36. After the conductive connection part 23 of the conductive part 200 extends out of the outside through the avoidance opening 35, the elastic fastener 400 is used to fasten the first clamping part 31 and the second clamping part 32.

[0073] When buckling, the buckling edge a of the elastic buckling piece 400 is placed in the first groove 312 of the first buckling part 311, the buckling edges b on both sides of the buckling edge a are respectively wrapped around the outside of the first buckling part 311 and the outside of the second buckling part 321 and are close to the second groove 322 of the second buckling part 321, and the buckling edges c are respectively placed in the second groove 322 from both sides of the second buckling part 321, and the buckling edge d is stretched into the limiting cavity 323 of the second clamping piece 32 to form a buckling state.

[0074] In the buckling state, the elastic buckling piece 400 continuously buckles the first clamping piece 31 and the second clamping piece 32, so that the distance between the first clamping piece 31 and the second clamping piece 32 continuously decreases until the first clamping piece 31 and the second clamping piece 32 are pressed on the conductive part 200 and are contacted with the electrode layer of the conductive part 200 to limit the clamping distance.

[0075] In use, after the external power supply is electrically connected to the conductive wiring part 23 and started, the current reaches the conductive heating layer through the conductive wiring part 23 and the electrode layer of the surface A, and the current flows back from the electrode layer of the surface B to form a power supply loop, the conductive heating layer is powered on, the hole space of the first through hole 12 is heated, all the conductive heating layers of the first through hole 12 form a parallel or series connection relationship, and the airflow passing through all the first through holes 12 is heated to achieve the heating effect.

[0076] On this basis, a temperature control device 500 can also be arranged between the heating body and the external power supply, the temperature control device 500 is used to detect and control the heating temperature of the conductive heating layer in real time, the overall temperature of the heating body is controlled, overheating and scalding of the user are avoided, and the temperature of the airflow passing through the first through hole 12 can also be controlled.

[0077] When disassembling, the buckling edges 41 are pulled apart one by one to release the first buckling part 311 or the second buckling part 321, and finally the elastic buckling piece 400 no longer contacts the first buckling part 311 or the second buckling part 321, forming a loose buckling state, and the first clamping piece 31 and the second clamping piece 32 no longer have the elastic clamping tightening force in the loose buckling state, so that they can be easily disassembled for maintenance, repair or replacement, and are convenient for users and workers to use.
