Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the present invention.

[0019] like Figure 1 As shown in the figure, the dual-voltage heating structure described in this embodiment includes a substrate 100, which is made of a material with good thermal conductivity, such as ceramic or metal. The substrate 100 can be configured as a plate or a tube, depending on the actual application scenario. The surface of the substrate 100 is provided with a plurality of heating resistor lines 200 arranged in parallel at intervals. For example, the surface of the substrate 100 is provided with M heating resistor lines 200, where M is a positive integer and M is greater than 1. The surface of the substrate 100 is also provided with a first electrode 300, a second electrode 400, a third electrode 500, and a fourth electrode 600.

[0020] One end of the first electrode 300 is electrically connected to one end of a part of the heating resistance lines 200 in the arrangement direction of the heating resistance lines 200, for example, one end of the first electrode 300 is electrically connected to one end of N heating resistance lines 200, N is a positive integer, and N is less than M; the other end of the first electrode 300 extends a first connecting part 301; one end of the second electrode 400 is electrically connected to the other end of all the parallel heating resistance lines 200; the other end of the second electrode 400 extends a second connecting part 401; the third electrode 500 is located between the first electrode 300 and the second electrode 400;

[0021] One end of the third electrode 500 is electrically connected to the other end of all the parallel heating resistance lines 200; the other end of the third electrode 500 extends a third connecting part 501; one end of the fourth electrode 600 is electrically connected to one end of the remaining heating resistance lines 200, that is, one end of the fourth electrode 600 is electrically connected to one end of M-N heating resistance lines 200; the other end of the fourth electrode 600 is electrically connected to one end of the second electrode 400. Preferably, the third electrode 500 is electrically connected to the center position of each heating resistance line 200; of course, the third electrode 500 can also be arranged at other positions, which can be set according to actual application needs.

[0022] The third electrode 500 is located at the center position in this embodiment. Specifically, if the application scenario is a first voltage, the first voltage can be set to 220V, 24V, etc., the first voltage is connected to the first connecting part 301 and the second connecting part 401, the third connecting part 501 is suspended, the third electrode 500 divides each heating resistance line 200 into left and right parts, at this time, the left part of the N heating resistance lines 200 is connected in parallel to form a first resistance R1, the right part of the M heating resistance lines 200 and the left part of the M-N heating resistance lines 200 are connected in parallel to form a second resistance R2, and the first resistance R1 and the second resistance R2 are connected in series to work, thereby providing a large power heating demand; for example, assuming that the resistance value of each heating resistance line 200 is a, and the voltage of the first voltage is VH, then the first resistance R1=a / (2*N), the second resistance R2=a / (2*(2M-N)), at this time, the heating power P1=VH*VH / (a / (2*N)+a / (2*(2M-N)));

[0023] If the application scenario is the second voltage and the second voltage is less than the first voltage, the second voltage can be set to 110V, 12V, etc., the first connecting part 301 and the second connecting part 401 are short-circuited, and the second voltage is connected with the third connecting part 501, the third electrode 500 divides each heating resistor circuit 200 into two parts, at this time, the left and right parts of the M heating resistor circuits 200 are connected in parallel to form a third resistor R3, and then the heating work is carried out, so as to provide a large power heating demand; for example, assuming that the resistance value of each heating resistor circuit 200 is a, and the voltage of the second voltage is VL, then the third resistor R3=a / (M*4), at this time, the heating power P2=4*VL*VL*M / a.

[0024] The embodiment sets the heating resistor circuits 200 in parallel with intervals, and connects through the first electrode 300, the second electrode 400, the third electrode 500 and the fourth electrode 600, so that different resistance structure modes are combined by each heating resistor circuit 200 at different voltages, to meet the large power heating demand at different voltages, without separately setting a plurality of heating bodies, saving manufacturing cost and saving area, and improving the utilization rate of the heating resistor circuit 200.

[0025] The double-voltage heating structure provided in the embodiment, in some embodiments, the heating resistor circuit 200 is a thick film resistor layer. In this way, the structure is more reliable and has better stability.

[0026] The double-voltage heating structure provided in the embodiment, in some embodiments, the heating resistor circuit 200 is sintered on the surface of the base body 100 through silk screen printing; the structure is more reliable and has better stability.

[0027] As shown in Figure 1 The embodiment also provides a quick heating type heating module, which comprises the double-voltage heating structure as described above. The embodiment has all the beneficial effects of the double-voltage heating structure, which will not be repeated here.

[0028] The above is only a preferred embodiment of the utility model, so equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application range are included in the protection range of the utility model patent application.
