In the prior art, a heating element wrapped around the inner wall of a liquid-guiding element typically has two heating circuits along its axial direction. These two heating circuits are connected by multiple heat dissipation strips. As a result, the two heating circuits are spaced a certain distance apart, resulting in uneven temperature distribution in the atomization area of the heating element (i.e., the areas corresponding to the two heating circuits). This results in poor atomization and affects the puffing experience. Summary of the Invention

In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0043] See also Figure 1-4 As shown, on the one hand, the present application provides a heating element 10, which includes a first pin 11, a second pin 12 and a heating element 13. The heating element 13 is connected between the first pin 11 and the second pin 12, and is electrically connected to the battery rod through the first pin 11 and the second pin 12, so that the heating element 13 can generate heat when powered on and heat the aerosol matrix, so that the heated aerosol matrix can be atomized to generate aerosol.

[0044] The heating element 13 includes a first heating circuit 131, a second heating circuit 132, and a first heat dissipation bar 133. The first heating circuit 131 and the second heating circuit 132 each bend and extend along the first pin 11 toward the second pin 12. The first heat dissipation bar 133 is used to dissipate heat from at least one of the first heating circuit 131 and the second heating circuit 132.

[0045] In an embodiment of the present application, the first heating circuit 131 and the second heating circuit 132 are enclosed to form at least one mesh 134. Compared with the prior art in which the heating circuit needs to cooperate with the heat dissipation strip to form a mesh hole structure, the present application enables the first heating circuit 131 and the second heating circuit 132 to generate heat in a concentrated manner, thereby improving the atomization effect, thereby improving the fullness of the atomized taste, and thus improving the user's inhalation sample. In addition, it can also effectively shorten the length of the heating element 10 in the direction perpendicular to the extension of the first heating circuit 131, so that the heating element 10 can be more compact. Therefore, the miniaturization of the heating element 10 can be controlled, and the liquid guide 30 in the atomization module 100 can also be controlled to be more compact, thereby reducing the amount of raw materials used in the liquid guide 30 and effectively reducing production costs.

[0046] In addition, by arranging the first heat dissipation strip 133 to be located in the mesh 134, it is possible to ensure the heat dissipation effect of the first heating circuit 131 and the second heating circuit 132 while utilizing the first heat dissipation strip 133 to enhance the structural strength of the first heating circuit 131 and the second heating circuit 132. Further, when the heating element 10 is curled to the inner side of the liquid guide member 30, the effect of the first heating circuit 131 and the second heating circuit 132 fitting the liquid guide member 30 can be enhanced, thereby reducing the dry burning and gelatinization phenomenon of the liquid guide member 30 and the explosion of the aerosol matrix.

[0047] Among them, a first heat dissipation bar 133 can be connected only to the first heating circuit 131, or only to the second heating circuit 132, or can be connected to the first heating circuit 131 and the second heating circuit 132 at the same time, so that each first heat dissipation bar 133 can dissipate heat for the first heating circuit 131 and the second heating circuit 132 at the same time.

[0048] In the examples of this application, please refer to Figure 3-4 As shown, the first heating circuit 131 includes a first heating segment 1311 and a second heating segment 1312, and the first heating segment 1311 and the second heating segment 1312 are electrically connected; wherein, the first heating circuit 131 may have multiple first heating segments 1311 and multiple second heating segments 1312, and each of the two ends of the first heating segment 1311 is respectively connected to a second heating segment 1312, so that the multiple first heating segments 1311 and the multiple second heating segments 1312 are alternately connected first.

[0049] The second heating circuit 132 includes a third heating segment 1321 and a fourth heating segment 1322, and the third heating segment 1321 and the fourth heating segment 1322 are electrically connected; wherein, the second heating circuit 132 may have multiple third heating segments 1321 and multiple fourth heating segments 1322, and each of the two ends of the third heating segment 1321 is respectively connected to a fourth heating segment 1322, so that the multiple third heating segments 1321 and the multiple fourth heating segments 1322 are alternately connected first.

[0050] The first heating section 1311 , the second heating section 1312 , the third heating section 1321 and the fourth heating section 1322 enclose the mesh 134 , so that the first heating circuit 131 and the second heating circuit 132 can be close to each other and generate heat in a concentrated manner, thereby improving the atomization effect.

[0051] In an embodiment of the present application, for the first heating segment 1311, the second heating segment 1312, the third heating segment 1321 and the fourth heating segment 1322 that constitute the same mesh 134, the first heating segment 1311 and the third heating segment 1321 are close to the first pin 11, and the second heating segment 1312 and the fourth heating segment 1322 are close to the second pin 12.

[0052] Among them, one of the first heat dissipation bars 133 is connected between the first heating segment 1311 and the third heating segment 1321, so that the first heat dissipation bar 133 can effectively dissipate heat for the first heating segment 1311 and the third heating segment 1321, thereby effectively reducing the respective temperature extremes of the first heating segment 1311 and the third heating segment 1321, and strengthening the structural strength of the first heating segment 1311 and the third heating segment 1321; another of the first heat dissipation bars 133 is connected between the second heating segment 1312 and the fourth heating segment 1322, so that the first heat dissipation bar 133 can effectively dissipate heat for the second heating segment 1312 and the fourth heating segment 1322, thereby effectively reducing the respective temperature extremes of the second heating segment 1312 and the fourth heating segment 1322, and greatly strengthening the structural strength of the second heating segment 1312 and the fourth heating segment 1322.

[0053] In the examples of this application, please refer to Figure 4 As shown, a first heat dissipation bar 133 is connected between the first midpoint M1 of the first heating segment 1311 and the third midpoint of the third heating segment 1321. Therefore, the high temperature extremes of the first heating segment 1311 and the third heating segment 1321 can be effectively lowered, thereby lowering the maximum temperatures of the first heating segment 1311 and the third heating segment 1321, so that the temperatures of various regions of the first heating segment 1311 are more uniform, and the temperatures of various regions of the third heating segment 1321 are more uniform.

[0054] In addition, the first heat dissipation bar 133 divides the first heating segment 1311 into two equal-length first sub-heating segments 13111, and divides the third heating segment 1321 into two equal-length third sub-heating segments 13211. Therefore, the distance from one end of each first sub-heating segment 13111 away from the first heat dissipation bar 133 to the first heat dissipation bar 133 is equal, so that the first heat dissipation bar 133 can also efficiently and evenly dissipate heat for the two first sub-heating segments 13111, and the distance from one end of each third sub-heating segment 13211 away from the first heat dissipation bar 133 is equal, so that the first heat dissipation bar 133 can also efficiently and evenly dissipate heat for the two third sub-heating segments 13211.

[0055] Another first heat dissipation bar 133 is connected between the second midpoint of the second heating segment 1312 and the fourth midpoint M4 of the fourth heating segment 1322. Therefore, the high temperature extremes of the second heating segment 1312 and the fourth heating segment 1322 can be effectively lowered, thereby lowering the maximum temperatures of the second heating segment 1312 and the fourth heating segment 1322, so that the temperatures of various areas of the second heating segment 1312 are more uniform, and the temperatures of various areas of the fourth heating segment 1322 are more uniform.

[0056] In addition, the first heat dissipation bar 133 divides the second heating segment 1312 into two second sub-heating segments 13121 of equal length, and divides the fourth heating segment 1322 into two fourth sub-heating segments 13221 of equal length. Therefore, the distance from one end of each second sub-heating segment 13121 away from the first heat dissipation bar 133 to the first heat dissipation bar 133 is equal, so that the first heat dissipation bar 133 can also efficiently and evenly dissipate heat for the two second sub-heating segments 13121, and the distance from one end of each fourth sub-heating segment 13221 away from the first heat dissipation bar 133 is equal, so that the first heat dissipation bar 133 can also efficiently and evenly dissipate heat for the two fourth sub-heating segments 13221.

[0057] In an embodiment of the present application, the first heating segment 1311 extends along a first direction, the second heating segment 1312 extends along a second direction, the third heating segment 1321 extends along a third direction, and the fourth heating segment 1322 extends along a fourth direction, wherein the first direction and the fourth direction are parallel to each other, and the second direction and the third direction are parallel to each other. Therefore, the mesh 134 enclosed by the first heating segment 1311, the second heating segment 1312, the third heating segment 1321 and the fourth heating segment 1322 is a parallelogram.

[0058] Furthermore, the first heating section 1311, the second heating section 1312, the third heating section 1321, and the fourth heating section 1322 are of equal length, so that the mesh 134 enclosed by the first heating section 1311, the second heating section 1312, the third heating section 1321, and the fourth heating section 1322 is diamond-shaped. This ensures that the two first heat dissipating bars 133 within each mesh 134 are of the same length, and the two first heat dissipating bars 133 can uniformly dissipate heat from the first heating section 1311, the second heating section 1312, the third heating section 1321, and the fourth heating section 1322, respectively.

[0059] In the examples of this application, please refer to Figure 4 As shown, each first heat dissipation strip 133 is connected to at least one first puncture portion 1351. When the heating element 13 is in a flat state, the first puncture portion 1351 does not extend out of the heating element 13; when the heating element 13 is in a curled state, the first puncture portion 1351 protrudes from the outside of the heating element 13, so that the first puncture portion 1351 can be inserted into the inner side of the curled liquid guide member 30, so that the heating element 13 and the liquid guide member 30 can be in close contact with each other, and then the first heating circuit 131 and the second heating circuit 132 can both be stably attached to the liquid guide member 30, so that the first heating circuit 131 and the second heating circuit 132 can stably heat the aerosol matrix adsorbed on the liquid guide member 30, thereby improving the atomization stability and avoiding the dry burning phenomenon of the first heating circuit 131 and the second heating circuit 132, as well as avoiding the explosion of the aerosol matrix.

[0060] In one embodiment, three first puncture portions 1351 are connected to each of the heat dissipation strips, one of which is located in the middle of the first heat dissipation strip 133, and the other two first puncture portions 1351 are respectively located at the first connection between the first heat dissipation strip 133 and the first heating circuit 131 and at the second connection between the first heat dissipation strip 133 and the second heating circuit 132.

[0061] Furthermore, three first puncture portions 1351 are respectively provided on the two first heat dissipation bars 133 in each mesh 134. One of the first puncture portions 1351 on the first heat dissipation bar 133 connected to the first heating segment 1311 and the third heating segment 1321 is located in the middle of the first heat dissipation bar 133, and the other two first puncture portions 1351 are respectively located at the first connection between the first heat dissipation bar 133 and the first heating segment 1311, and the second connection of the third heating segment 1321; one of the first puncture portions 1351 on the other heat dissipation bar connected to the second heating segment 1312 and the fourth heating segment 1322 is located in the middle of the first heat dissipation bar 133, and the other two first puncture portions 1351 are respectively located at the first connection between the first heat dissipation bar 133 and the second heating segment 1312, and the second connection of the fourth heating segment 1322.

[0062] By respectively providing the first piercing portion 1351 at the first connection and the second connection, the first heating section 1311, the second heating section 1312, the third heating section 1321 and the fourth heating section 1322 can be more closely attached to the inner side of the liquid guide member 30, thereby ensuring the atomization effect.

[0063] Two first heat dissipation strips 133 are provided in each of the mesh holes 134. When the heating element 13 is in a flat state, the first puncture portions 1351 respectively connected to the two first heat dissipation strips 133 located in the same mesh hole 134 are opposite to each other. Therefore, in the process of curling the heating element 10 inside the liquid guide member 30, the first puncture portions 1351 respectively on the two first heat dissipation strips 133 located in the same mesh hole 134 will be respectively inserted into the liquid guide member 30, so that the first heating segment 1311, the second heating segment 1312, the third heating segment 1321 and the fourth heating segment 1322 corresponding to the mesh hole 134 will be close to the inner wall of the corresponding liquid guide member 30.

[0064] In the examples of this application, please refer to Figure 3As shown, the heating element 13 further includes a second heat dissipation bar 136 and a third heat dissipation bar 137. A second heat dissipation bar 136 is connected to the first bend of the first heating circuit 131 corresponding to each mesh hole 134, and each second heat dissipation bar 136 extends in a direction away from the second heating circuit 132. A third heat dissipation bar 137 is connected to the second bend of the second heating circuit 132 corresponding to each mesh hole 134, and each third heat dissipation bar 137 extends in a direction away from the first heating circuit 131. Therefore, the second heat dissipation bar 136 and the third heat dissipation bar 137 extend in opposite directions, so that the second heat dissipation bar 136 cooperates with the first heat dissipation bar 133 to dissipate heat from the first heating segment 1311 and the second heating segment 1312, and the third heat dissipation bar 137 cooperates with the first heat dissipation bar 133 to dissipate heat from the third heating segment 1321 and the fourth heating segment 1322.

[0066] Among them, the first connection part 138 and the second connection part 139 are respectively provided with a second puncture part 1352. When the heating element 13 is in a flat state, the second puncture part 1352 on the first connection part 138 and the second puncture part 1352 on the second connection part 139 are opposite to each other. When the heating element 13 is in a curled state, the second puncture part 1352 on the first connection part 138 and the second puncture part 1352 on the second connection part 139 respectively protrude from the outside of the heating element 13 and are inserted into the corresponding inner wall of the liquid guide part 30, so that the heating net can be tightly attached to the liquid guide part 30, thereby improving the connection stability between the heating net and the liquid guide part 30.

[0067] On the other hand, see Figure 5-6 As shown, the present application further provides an atomization module 100, which includes any of the heating elements 10 described above. Therefore, the atomization module 100 has all the above-mentioned beneficial effects, which will not be repeated here.

[0068] Furthermore, the atomization module 100 further includes an atomization tube 20 and a liquid guide 30 . The liquid guide 30 is at least partially curled and disposed inside the atomization tube 20 . The heating element 10 is curled and disposed inside the liquid guide 30 .

[0069] In addition, the atomization module 100 also includes a mounting tube 40, and the liquid guide member 30 includes a first sub-liquid guide member 31 and a second sub-liquid guide member 32. The first sub-liquid guide member 31 is curled and arranged on the inner side of the atomization tube 20, and the mounting tube 40 is inserted into the inner side of the curled first sub-liquid guide member 31, and the second sub-liquid guide member 32 is curled and arranged on the inner side of the mounting tube 40. The heating element 10 is curled and arranged on the inner side of the second sub-liquid guide member 32.

[0070] By providing the first sub-liquid-guiding member 31 and the second sub-liquid-guiding member 32 , the liquid-locking capability of the atomization module 100 can be effectively improved, and the risk of leakage of aerosol matrix through the atomization module 100 can be reduced.

[0075] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0076] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
