[0030] like Figure 1 As shown, a heating element for heating cigarettes includes at least one substrate 2 and at least two heating elements 3. The heating elements 3 are attached to the surface of the substrate. The substrate 2 is wound, forming a receiving cavity 1 in the middle. The receiving cavity 1 is used to place removable smoke-generating material. The heating elements and substrate are arranged alternately in sequence, such that a heating element is provided on both sides of each substrate layer. The multiple heating elements 3 are arranged radially along the receiving cavity 1. The heating elements 3 are connected to an external power source through electrode leads 4 and a control circuit. In this embodiment, the substrate 2 is a ceramic substrate.
[0031] Example 1:
[0032] like Figure 2 As shown, the substrate 2 can be wound into a cylindrical or near-cylindrical shape. The heating element 3 includes a first heating element 31 and a second heating element 32. The first heating element 31 is attached to the inner wall of the substrate 2, and the second heating element 32 is attached to the outer wall of the substrate 2. The substrate 2 is disposed between the first heating element 31 and the second heating element 32. The substrate 2 has the structural strength to support the heating element, and the substrate 2 also makes the first heating element 31 and the second heating element 32 electrically insulated.
[0033] like Figure 3 As shown, the first heating element 31 is configured with two heating zones: a first heating zone 311 and a second heating zone 312. The heating power of the first heating zone 311 is set to 70%-99% of the total heating power of the first heating element 31, causing the temperature of the first heating zone 311 to rise rapidly to 180℃-350℃ during operation. The second heating zone 312, due to its lower heating power, maintains a lower temperature. To ensure the heating speed of the first heating zone 311, its area is set to 5%-40% of the total area of the first heating element 31, and the area of the second heating zone 312 is set to 60%-95% of the total area of the first heating element 31.
[0034] The second heating element 32 is configured with two heating zones: a third heating zone 321 and a fourth heating zone 322. The heating power of the fourth heating zone 322 is set to 70%-90% of the total heating power of the second heating element 32, so that when the second heating element 32 is working, the temperature of the fourth heating zone 322 is maintained at the atomization temperature of the suction material, which is 180℃-350℃. The third heating zone 321, because of its lower heating power, will maintain its temperature at the insulation temperature of the suction material, which is 100℃-200℃.
[0035] The first heating area 311 of the first heating element 31 corresponds to the third heating area 321 of the second heating element 32 in terms of position and area, and the second heating area 312 of the first heating element 31 corresponds to the fourth heating area 322 of the second heating element 32 in terms of position and area.
[0036] When the first heating element 31 is working, the upper part of the receiving cavity 1 is maintained at the atomization temperature of the extractable material (180℃-350℃), and the lower part is maintained at the insulation temperature of the extractable material (100℃-200℃). When the second heating element 32 is working, the lower part of the receiving cavity 1 is maintained at the atomization temperature of the extractable material (180℃-350℃), and the upper part is maintained at the insulation temperature of the extractable material (100℃-200℃). By setting the working time of the two heating elements, the heating element obtains different high-temperature areas at different times, thereby achieving the effect of segmented and timed atomization of the extractable material placed in the receiving cavity 1.
[0037] The heating element 3 is connected to electrode leads welded to the periphery of the heating body of this device, and is connected to an external power source through the electrode leads. Holes 201 are provided on the substrate 2, and two first leads 41 are connected to the two poles of the first heating element 31 through the holes 201. Two second leads 42 are connected to the two poles of the second heating element 32.
[0038] like Figure 4 As shown, the positional relationship of the heating element and the substrate 2 is displayed. The first heating element 31 and the second heating element 32 are vertically arranged on both sides of the substrate 2. The first heating element 31 and the second heating element 32 are the same in height. The tops of the first heating element 31 and the bottoms of the second heating element 32 are aligned with each other.
[0039] After the first heating element 31, the substrate 2, and the second heating element 32 form the heating body of this device, the first heating element 31, the substrate 2, and the second heating element 32 are arranged in a radial direction from the inside to the outside, with the central axis of the accommodating cavity 1 as the starting point.
[0040] like Figure 5 As shown in the left figure, substrate 2 is wound into a circle, as follows:Figure 5 As shown in the right figure, the substrate 2 is wound into a near-circular shape, the first heating element 31 is attached to the inner wall of the substrate 2, and the second heating element 32 is attached to the outer wall of the substrate 2. The first heating element 31 and the second heating element 32 are arranged radially along the center point of the cross section.
[0041] Example 2:
[0042] The difference between this embodiment and Embodiment 1 is that this device is configured with three or more heating stages:
[0043] like Figure 6 As shown, the substrate includes a first substrate 21 and a second substrate 22. The first substrate 21 is wound into a cylindrical or near-cylindrical shape, forming an internal cavity 1. A first heating element 31 is attached to the inner wall of the first substrate 21, and a second heating element 32 is attached to the outer wall of the first substrate 21. The second substrate 22 is disposed on the outer ring of the first substrate 21 and contacts the second heating element. A third heating element 33 is attached to the outer wall of the second substrate 22. The first substrate 21 and the second substrate 22 are disposed between the three heating elements to support the structural strength of the heating body and to provide electrical insulation between the heating elements.
[0044] The first heating element 31 has a first heating zone 311 and a second heating zone 312. The heating power of the first heating zone 311 is set to 70%-99% of the total heating power of the first heating element 31, so that when the first heating element 31 is working, the temperature of the first heating zone 311 rises rapidly to 180℃-350℃, while the temperature of the second heating zone 312, due to its lower heating power, remains at a lower temperature. To ensure the heating speed of the first heating zone 311, the area of the first heating zone 311 is set to 5%-40% of the total area of the first heating element 31, and the area of the second heating zone 312 is set to 60%-95% of the total area of the first heating element 31.
[0045] The second heating element 32 is provided with a third heating zone 321, a fourth heating zone 322 and a fifth heating zone 323. The heating power of the fourth heating zone 322 is set to 70%-90% of the total heating power of the entire second heating element 32, so that when the second heating element 32 is working, the temperature of the fourth heating zone 322 is maintained at the atomization temperature of the suction material, 180℃-350℃. Because the heating power of the third heating zone 321 and the fifth heating zone 323 is lower, their temperature is maintained at the heat preservation temperature of the suction material, 100℃-200℃.
[0046] The third heating element 33 is provided with a sixth heating area 331 and a seventh heating area 332, wherein the heating power of the seventh heating area 332 is set to 70%-90% of the heating power of the entire third heating element 33, so that when the third heating element 33 is working, the temperature of the seventh heating area 332 is maintained at the atomization temperature 180℃-350℃ of the smokable material, while the temperature of the sixth heating area 331 is maintained at the heat preservation temperature 100℃-200℃ of the smokable material because of the lower heating power.
[0047] The first heating area 311 of the first heating element 31 corresponds in position and matches in area with the third heating area 321 of the second heating element 32, the second heating area 312 of the first heating element 31 corresponds in position and matches in total area with the fourth heating area 322 and the fifth heating area 323 of the second heating element 32, the sixth heating area 331 of the third heating element 33 corresponds in position and matches in total area with the third heating area 321 and the fourth heating area 322 of the second heating element 32, and the seventh heating area 332 of the third heating element 33 corresponds in position and matches in area with the fifth heating area 323 of the second heating element 32.
[0048] When the first heating element 31 is working, the upper part of the containing cavity 1 is maintained at the atomization temperature 180℃-350℃ of the smokable material, and the middle part and the lower part are maintained at the heat preservation temperature 100℃-200℃ of the smokable material; when the second heating element 32 is working, the middle part of the containing cavity 1 is maintained at the atomization temperature 180℃-350℃ of the smokable material, and the upper part and the lower part are maintained at the heat preservation temperature 100℃-200℃ of the smokable material; when the third heating element 33 is working, the lower part of the containing cavity 1 is maintained at the atomization temperature 180℃-350℃ of the smokable material, and the upper part and the middle part are maintained at the heat preservation temperature 100℃-200℃ of the smokable material; by setting the working time of the three heating elements, different high-temperature areas of the heating body are obtained at different times, thereby achieving the effect of segmented and timed atomization of the smokable material placed in the containing cavity 1.
[0049] The heating element is connected with the electrode lead welded on the periphery of the heating body, and is connected with the external power source through the electrode lead. The first base material 21 is provided with a first hole 211, the second base material 22 is provided with a second hole 221 and a third hole 222, and the first lead 41 is connected with the two poles of the first heating element 31 through the first hole 211 and the second hole 221. The second lead 42 is connected with the two poles of the second heating element 32 through the third hole 222. The third lead 43 is connected with the two poles of the third heating element 33.
[0050] As Figure 8As shown, the first heating element 31, the second heating element 32 and the third heating element 33 keep the same in the height direction, the top aligns with the top, and the bottom aligns with the bottom. The first substrate 21 is placed between the first heating element 31 and the second heating element 32, and the second substrate 22 is placed between the second heating element 32 and the third heating element 33, which guarantees that the first heating element 31, the second heating element 32 and the third heating element 33 are arranged in the radial direction from inside to outside along the axis of the heating body.
