The aerosol-generating substance layer 15 may be a solid, a paste, a jelly or the like. It can be understood that the heating sheet 12 coated with the aerosol-producing substance 15 is directly placed in the heating inhaler, and the gas or aerosol can be heated to generate additional tobacco products in the casing 11 without additional Or an aerosol-generating substance such as a drug is convenient and quick, and the heating piece is easy to clean. Further, the heater chip 12 has a simple structure and a low cost, and can be used at one time. It will be appreciated that the heater chip 12 can also be used multiple times.

[0041] As shown in FIG. 4, the heating sheet 12 can be used for a suction heater for heating an aerosol-generating substance such as a tobacco product or a medicine, and the heating sheet 12 includes a heating portion 121 and an electrical connection portion 122 connected to the heating portion 121. And an aerosol-generating material layer 15 such as a tobacco product or a drug coated on the surface of the heating unit 121. Electrical connection 12 2 includes a positive electrode electrical connection portion and a negative electrode electrical connection portion that are spaced apart from each other at the bottom of the heating portion 121 to be electrically connected to the positive electrode and the negative electrode of the battery assembly 20, respectively. Preferably, the heating portion 121 and the electrical connection portion 122 are of a unitary structure, which simplifies the manufacturing process and provides a more stable current flow.

[0042] The heating portion 121 has a flat sheet shape, is convenient to manufacture, and takes up a small space, and the space is uniformly dissipated. The heating portion 121 includes at least one slit structure 13 for guiding the flow of current to make the heat generation uniform. The at least one slit structure 13 may include at least two slit structures 13; the at least two slit structures 13 include two or N-channel slit structures, and the N is greater than two, and the slit structures separate the heating portions 121 by N+1 series.

[0043] As shown in FIG. 2, the N-channel slit structure 13 includes a first slit structure 131, a second slit structure 132, and a third slit structure 133 which are sequentially arranged, wherein the first slit structure 131 and the third slit structure 133 is respectively extended from the bottom edge of the heating portion 121 toward the top edge, and the second slit structure 132 extends from the top edge of the heating portion 121 toward the bottom edge. The slit structure 13 plans the heating portion 121 into a regular series circuit, and the current flows through the electrical connection portion 122 into the heating portion 121, so that the entire heating portion 121 generates heat uniformly, and the heating portion 121 at the end connected to the electrical connection portion 122 is prevented from being The heat loss during heat conduction is faster than that of the heating portion 121 at the end of the electrical connection portion 122, resulting in uneven heating of the heating portion 121 as a whole.

As shown in FIG. 5, the first slit structure 131, the second slit structure 132, and the third slit structure 133 sequentially partition the first heating segments on both sides and connected to the electrical connection portion 122 and at least one in the middle. a second heating section, the first heating section having a width smaller than the second heating section. And the width of the first heating segment is gradually widened from a direction close to the electrical connection portion to away from the electrical connection portion. The first heating section includes a first heating unit 1211 and a fourth unit 1214, and the second heating section includes a second heating unit section 1212 adjacent to the first heating unit 1211 and a third heating unit 1213 adjacent to the fourth heating unit 1214. The first heating unit 1211 and the fourth heating unit 1214 are respectively connected to the positive electrode electrical connection portion and the negative electrode electrical connection portion, and the widths of the first heating unit 1211 and the fourth heating unit 1214 are smaller than the second heating unit 1212 and the third heating unit The width of 1213. Since the first heating unit 1211 and the fourth heating unit 1214 are located at the edge of the heating sheet 12, the heat dissipation speed is fast; and since the first heating unit 1211 and the fourth heating unit 1214 are connected to the electrical connection portion 1 22, heat is lost due to heat conduction. fast.

Since the heating power of the first heating unit 1211 and the fourth heating unit 1214 is large, the width of the first slit structure 131 and the third slit structure 133 is larger than the width of the second slit structure 132, so that the first heating unit 1211 and the first heating unit 1211 can be prevented. The temperature of the side of the fourth heating unit 1214 near the inner side of the heating sheet is too high, so that the overall temperature of the heating portion 121 is more uniform. Specifically, the ratio of the width of the first slit structure 131 and the third slit structure 133 to the width of the second slit structure 132 is controlled to be between 1.8 and 2.2. In some embodiments, the width of the first slit structure 131 and the third slit structure 133 is 0.1 mm, and the width of the second slit structure 132 is 0·05 mm.

Preferably, the mount 14 is made of a high temperature resistant, non-conductive material such as ceramic, ceramic core, mica plate or the like.

4, the electrical connection portion 122 may include a horizontal portion 1221 and a vertical portion 1222; the horizontal portion 1221 connects the heating portion 121 and the vertical portion 1222, and is located on the same plane as the heating portion 121; the vertical portion 1222 is perpendicular to the water The flat portion 1221 is parallel to the axial direction of the casing 11, and the vertical portion 1222 is perpendicular to the axial direction of the casing 11. The heating piece 121 is mounted on the fixed seat 14, and the horizontal portion 1221 is fixed to the linear abutting portion 141.
