[0043] Please refer to Figures 1 to 6 , and other drawings. Among them, Figure 1 is a perspective view of the atomization structure 100 provided by some embodiments of the present application, Figure 2 is a top view of the atomization structure 100 provided by Figure 1 , Figure 3 is an exploded view of the atomization structure 100 provided by Figure 1 , Figure 4 is a perspective view of the jig rod 10, the pin 222 and the fixing bracket 40 of the atomization structure 100 provided by Figure 1 , Figure 5 is a sectional view along A-A, Figure 1 is a sectional view along A-A, Figure 6 is a perspective view of the atomization core 20 of the atomization structure 100 provided by Figure 1 . The jig rod 10 provided by the embodiments of the present application is applied to the heating element 22 of the atomization core 20. The atomization core 20 includes a liquid guide 21 and a heating element 22 arranged on the liquid guide 21, and the heating element 22 includes a heating body 221 and a pin 222 arranged on the heating body 221.

[0044] Among them, the heating body 221 is the part of the heating element 22 for heating, which is the main part of the heating element 22.

[0045] Among them, the pin 222 is arranged on the heating body 221 and is electrically connected with the heating body 221. The pin 222 is used to electrically connect the heating body 221 and the power supply. In operation, current can flow to the heating body 221 through the pin 222 to make the heating body 221 heat up to heat the aerosol generating substrate. Among them, the power supply can be a battery of the aerosol generating device.

[0046] Among them, the liquid guide 21 can be but is not limited to a liquid guide cotton with cotton fiber material.

[0047] The outer peripheral wall of the jig rod 10 provided by the embodiments of the present application is provided with a groove 101. Among them, as Figures 1 to 4As shown, the groove 101 penetrates both ends of the jig rod 10 along the axial direction Z; or, the groove 101 penetrates one end of the jig rod 10 along the axial direction Z. The groove 101 is used for inserting the pin 222 of the heating element 22 to position the pin 222.

[0048] The jig rod 10 refers to a structure in a substantially cylindrical shape. The axial direction Z refers to the extending direction of the jig rod 10, i.e., the length direction of the jig rod 10.

[0049] The groove 101 refers to a recess structure formed on the outer peripheral wall of the jig rod 10.

[0050] It should be noted that when the jig rod 10 is used, the atomization core 20 can be sleeved on the outer periphery of the jig rod 10, so that the liquid guide 21 is sleeved on the outer periphery of the jig rod 10, the heating main body 221 of the heating element 22 is arranged between the outer peripheral wall of the jig rod 10 and the inner peripheral wall of the liquid guide 21, and the pin 222 is inserted into the groove 101. Based on this, the jig rod 10 can avoid the pin 222 through the groove 101.

[0051] The jig rod 10 provided by the embodiment of the present application has the groove 101 arranged on the outer peripheral wall of the jig rod 10, and the groove 101 penetrates one end or both ends of the jig rod 10 along the axial direction Z. After the atomization core 20 is wrapped on the outer periphery of the jig rod 10, the pin 222 of the heating element 22 can be inserted and positioned in the groove 101 of the jig rod 10, so that the jig rod 10 can avoid the pin 222. In this way, the problem that the liquid guide 21 is damaged by the heating element 22 due to the extrusion of the pin 222 on the jig rod 10 can be improved, so that the liquid guiding effect of the liquid guide 21 can be effectively guaranteed, the problem of the atomization core 20 being damaged can be improved, and the atomization effect of the aerosol generating device can be improved.

[0052] In addition, by penetrating one end or both ends of the jig rod 10 along the axial direction Z through the groove 101, after the positions of the liquid guide 21 and the heating element 22 are fixed, the jig rod 10 can be easily pulled out of the atomization core 20 along the axial direction Z. The jig rod 10 can be pulled out after the atomization core 20 is assembled to the atomization support 30 and the fixing support 40 which will be described below, or after the atomization core 20 is assembled to the aerosol generating device.

[0053] It should be noted that the number of pins 222 is two, and the polarities of the two pins 222 are positive and negative, respectively.

[0054] In some embodiments, please refer to Figures 1 to 5 in combination with other drawings. The number of grooves 101 is multiple, and the multiple grooves 101 are arranged at intervals along the circumferential direction E.

[0055] Specifically, the multiple grooves 101 are arranged at intervals along the circumferential direction E on the outer peripheral wall of the jig rod 10.

[0056] Wherein, the circumferential direction E refers to the circumferential direction of the jig rod 10, and the circumferential direction E is perpendicular to the axial direction Z.

[0057] Wherein, the number of the grooves 101 can be two or more than two.

[0058] In some embodiments, please refer to Figures 1 to 5 , and combine with other drawings. The number of the grooves 101 is two.

[0059] In this way, the two pins 222 on the heating element 22 can be inserted into the two grooves 101 one by one. In this way, on the one hand, the jig rod 10 can better avoid the pins 222 to improve the problem that the pins 222 are extruded and damaged under the extrusion of the jig rod 10. On the other hand, the two grooves 101 correspond to the insertion of the two pins 222 respectively, so that the two pins 222 can be positioned, which is convenient for the subsequent positioning and installation of the pins 222.

[0060] In some embodiments, the number of the grooves 101 is more than two. That is, the number of the grooves 101 can be three, four, etc.

[0061] In this way, the two pins 222 can be inserted into the two grooves 101 respectively. In this way, it is convenient for the jig rod 10 to avoid the two pins 222.

[0062] In some embodiments, please refer to Figures 1 to 5 , and combine with other drawings. The grooves 101 penetrate through both ends of the jig rod 10 along the axial direction Z.

[0063] In this way, on the one hand, it is convenient for the molding of the jig rod 10. On the other hand, when the jig rod 10 is assembled to the atomization core 20, it is not necessary to distinguish the two ends of the jig rod 10, so that after the position of the atomization core 20 is fixed, the jig rod 10 can be pulled out from the atomization core 20 along the axial direction Z.

[0064] In some embodiments, please refer to Figure 2 and Figure 5 , and combine with other drawings. In the depth direction of the groove 101, the groove 101 is gradually expanded outward.

[0065] By gradually expanding the groove 101 outward, it is convenient for the pin 222 to be inserted into the groove 101 during the process of inserting the pin 222 into the groove 101, so as to facilitate the installation of the jig rod 10 and the atomization core 20, and thus improve the assembly efficiency of the aerosol generating device.

[0066] In some embodiments, please refer to Figure 2 and Figure 5, and in combination with other drawings. The cross section of the jig rod 10 perpendicular to the axial direction Z is circular.

[0067] In the embodiment, as shown in Figure 5 , the cross section of the jig rod 10 perpendicular to the axial direction Z is circular.

[0068] The cross section of the jig rod 10 perpendicular to the axial direction Z is circular, so that the jig rod 10 is substantially cylindrical.

[0069] In this way, the outer peripheral wall of the jig rod 10 is provided with a circular arc transition, which can improve the problem that the outer peripheral wall of the jig rod 10 is too sharp and damages the atomizing core 20.

[0070] In the embodiment, as shown in Figure 2 and Figure 5 , the cross section of the jig rod 10 perpendicular to the axial direction Z is circular, so that the depth direction of the groove 101 is the radial direction of the jig rod 10, that is, the radial direction of the jig rod 10. It can be understood that in the radial direction of the jig rod 10, the groove 101 is provided outwardly expanding. In which, the radial direction of the jig rod 10 is perpendicular to the axial direction Z.

[0071] In some embodiments, the jig rod 10 is a plastic rod, a glass rod or a metal rod.

[0072] By providing the jig rod 10 as a plastic rod, a glass rod or a metal rod, the structural hardness of the jig rod 10 is greater than that of the liquid guide 21, thereby helping the jig rod 10 to abut and support the heating element 22 to achieve the position fixing effect on the heating element 22.
