The power supply assembly 80 may also be in other shapes, such as a rectangular parallelepiped.

[0049] Please refer to Figure 4 In some embodiments, the battery cell holder 50 includes a bottom plate 51, a first side plate 52a and a second side plate 52b, the first side plate 52a and the second side plate 52b are both connected to the same end surface of the bottom plate 51, and the power supply installation cavity 504 is opened between the first side plate 52a and the second side plate 52b; the bottom plate 51 includes a first side edge 512 and a second side edge 514, the first side edge 512 and the power supply installation cavity 504 are respectively arranged on both sides of the first side plate 52a, and the second side edge 514 and the power supply installation cavity 504 are respectively arranged on both sides of the second side plate 52b, a part of the fixed wire through-holes 5102 are arranged along the first side edge 512 and penetrate the first side edge 512, and another part of the fixed wire through-holes 5102 are arranged along the second side edge 514 and penetrate the second side edge 514.

Through the above structure, when the power supply component 80 is installed in the power supply installation cavity 504, the power supply component 80 is located between the first side plate 52a and the second side plate 52b, and a part of the fixed wire through-holes 5102 are arranged along the first side edge 512 and pass through the first side edge 512, and another part of the fixed wire through-holes 5102 are arranged along the second side edge 514 and pass through the second side edge 514, so that the first side plate 52a separates the power supply component 80 from a part of the fixed wire through-holes 5102, and the second side plate 52b separates the power supply component 80 from another part of the fixed wire through-holes 5102, so that both the first side plate 52a and the second side plate 52b can separate the leads from the power supply component 80, so that when the power supply component 80 is installed into the power supply installation cavity 504, the power supply component 80 is not easy to squeeze the leads, so that the leads are disconnected from the circuit board 90 or the power contact sheet 60.

[0051] Specifically, in this embodiment, the bottom plate 51, the first side plate 52a and the second side plate 52b are all rectangular sheet structures, the first side plate 52a and the second side plate 52b are both perpendicular to the bottom plate 51, and the first side plate 52a and the second side plate 52b are symmetrically distributed relative to the central axis of the bottom plate 51.

[0054] Each fixed wire through hole 5102 corresponds to a first lead stopper 53 or a second lead stopper 54. Through the above structure, the first lead stopper 53 and the second lead stopper 54 can both stop the lead, so that the lead is more stably fixed in the fixed wire through hole 5102, reducing the possibility of the lead detaching from the fixed wire through hole 5102 when the aerosol generating device 100 vibrates during transportation or other situations, thereby improving the stability between the lead and the battery holder 50.

[0055] Specifically, in the present embodiment, the first lead limiter 53 has an "L"-shaped structure, and the second lead limiter 54 has the same structure as the first lead limiter 53; the first lead limiter 53, the second lead limiter 54 and the base plate 51 are integrally formed, and the two ends of the first lead limiter 53 are respectively connected to the two opposite side hole walls of the corresponding fixed wire through hole 5102, and the two ends of the second lead limiter 54 are also respectively connected to the two opposite side hole walls of the corresponding fixed wire through hole 5102.

[0057] In some embodiments, the first lead limiter 53 includes a first vertical wall 532 and a first parallel wall 534, one end of the first vertical wall 532 is connected to the side hole wall of the fixed wire through hole 5102, and the first parallel wall 534 is connected to the other end of the first vertical wall 532; the first vertical wall 532 is perpendicular to the bottom plate 51, and the first vertical wall 532 and the first side plate 52a are located on the same side of the bottom plate 51; the first parallel wall 534 is parallel to the bottom plate 51, and the vertical projection of the first parallel wall 534 on the bottom plate 51 overlaps with the corresponding fixed wire through hole 5102.

[0058] The second lead stopper 54 includes a second vertical wall 542 and a second parallel wall 544, one end of the second vertical wall 542 is connected to the side hole wall of the fixed wire through hole 5102, and the second parallel wall 544 is connected to the other end of the second vertical wall 542; the second vertical wall 542 is perpendicular to the bottom plate 51, and the second vertical wall 542 and the first side plate 52a are located on the same side of the bottom plate 51; the second parallel wall 544 is parallel to the bottom plate 51, and the vertical projection of the second parallel wall 544 on the bottom plate 51 overlaps with the corresponding fixed wire through hole 5102.

[0059] Through the above structure, the lead is placed between the gap between the first parallel wall 534 and the bottom plate 51, or between the second parallel wall 544 and the bottom plate 51, and then the first parallel wall 534 and the second parallel wall 544 limit the lead, so that the lead cannot move away from the end surface of the bottom plate 51.

[0060] Specifically, the first vertical wall 532, the first parallel wall 534, the second vertical wall 542, and the second parallel wall 544 are all rectangular block structures, and the first vertical wall 532 and the second vertical wall 542 have the same size, so that the spacing between the first parallel wall 534 and the bottom plate 51 is the same as the spacing between the second parallel wall 544 and the bottom plate 51. The shapes of the first parallel wall 534 and the second parallel wall 544 are both adapted to the shape of the fixed wire through hole 5102.
