[0019] like Figure 1-7As shown, this application provides an electronic cigarette with a long battery life, including a main unit 11 and a cartridge 1 detachably connected to the main unit 11. The main unit 11 has a receiving cavity 901 and a bracket 5 detachably disposed in the receiving cavity 901. The bracket 5 has an adapter space 501 corresponding to and communicating with the lower end of the receiving cavity 901. A battery cell 8 is disposed in the adapter space 501.

The battery cell 8 and the charging board 7 are electrically connected to the power board 6, and the power board 6 is electrically connected to the cartridge 1. It should be noted that by setting an adaptation space 501 of the same size as the receiving cavity 901 on the bracket 5 to adapt the battery cell 8, not only can the host 11 be adapted to power the large-volume, high-capacity battery cell 8, thereby extending the battery life of the electronic cigarette, but also because the bracket 5 is detachable inside the host 11, it can be removed and replaced when the power board 6 and the battery cell 8 fail.

[0020] In some embodiments, the charging board 7 is provided with a charging socket 701, and the host 11 is provided with a socket 906 corresponding to the charging socket 701. It should be noted that after the charging device is inserted into the charging socket 701 through the socket 906, the battery cell 8 can be charged through the charging board 7 and the power board 6.

[0021] In some embodiments, the bracket 5 is located inside the lower end of the receiving cavity 901, and the main unit 11 is provided with a positioning screw 10 for positioning the bracket 5 inside the lower end of the receiving cavity 901. The lower end of the receiving cavity 901 is used to receive the bracket 5, and the positioning screw 10 is designed to prevent the bracket 5 from moving inside the lower end of the receiving cavity 901.

[0022] In some embodiments, the top end of the bracket 5 corresponds to the upper end of the receiving cavity 901, and the lower end of the tobacco cartridge 1 is inserted into the upper end of the receiving cavity 901.

The power board 6 supplies power to the cartridge 1 through the conductive structure 1101. The conductive structure 1101 is used to conductively connect the cartridge 1. The conductive structure 1101 can be a conductive electrode post, wire, conductive contact, conductive pin, etc., but is not limited to these.

[0024] In some embodiments, the cavity wall corresponding to the receiving cavity 901 is provided with a snap-hole structure 1103, and the outer wall of the bracket 5 is provided with a snap-fit ​​structure 1102 corresponding to the snap-hole structure 1103. The bracket 5 is detachable within the receiving cavity 901 through the snap-hole structure 1103 and the snap-fit ​​structure 1102. The design of the snap-fit ​​structure 1102 and the snap-hole structure 1103 makes it easier to assemble and disassemble the bracket 5 within the receiving cavity 901, and the structure is simple and easy to design.

[0025] In some embodiments, the main unit 11 includes a main shell 9, a receiving cavity 901 formed within the main shell 9, and the shell wall of the main shell 9 serving as the cavity wall of the receiving cavity 901. The shell wall of the main shell 9 has a first snap hole 903 and a second snap hole 904 forming a snap hole structure 1103. The outer wall of the bracket 5 has a first snap 505 extending into the first snap hole 903 and a second snap 506 extending into the second snap hole 904. The first snap 505 and the second snap 506 constitute a snap structure 1102. The bracket 5 is detachable within the receiving cavity 901 via the first snap 505 extending into the first snap hole 903 and the second snap 506 extending into the second snap hole 904. The first snap hole 903 and the second snap hole 904 are integrally formed with the main shell 9 using a stamping process, eliminating the need for separate machining. The first snap 505 and the second snap 506 are integrally formed with the bracket 5 using an in-mold injection molding process.

[0026] In some embodiments, the bottom end of the bracket 5 has a connecting piece 502, and the bottom end of the connecting piece 502 has a support base 503 corresponding to the bottom end of the bracket 5. The space between the top end of the support base 503 and the bottom end of the bracket 5 forms an adaptation space 501, so that both ends of the battery cell 8 can extend into the lower end of the receiving cavity 901 from the adaptation space 501. The outer wall of the bracket 5 also has a groove 508, the power board 6 is disposed in the groove 508, the charging board 7 is disposed in the support base 503, the bottom end of the main body shell 9 has a socket 906 corresponding to the charging socket 701 on the charging board 7, the shell wall of the main body shell 9 also has a through hole 902, and the outer wall of the bracket 5 has an internal thread channel 504 corresponding to and communicating with the through hole 902. The bracket 5 is screwed into the internal thread channel 504 from the through hole 902 by the positioning screw 10, so that the bracket 5 is positioned in the lower end of the receiving cavity 901. The connecting piece 502, support base 503, adapter space 501, and groove 508 are integrally formed with the bracket 5, requiring no separate design or installation. The through hole 902 allows the positioning screw 10 to be screwed into the internal thread channel 504 outside the main body shell 9. After the tobacco cartridge 1 is inserted into the upper end of the receiving cavity 901, the positioning screw 10 provides support force to the upper end of the bracket 5, preventing the connecting piece 502 from bending under the pressure of the tobacco cartridge 1, which would cause the adapter space 501 to deform and the pressure ring battery 8 to bend. When the cartridge 1 is pulled out from the upper end of the receiving cavity 901, the magnetic attraction between the cartridge 1 and the bracket 5 is provided by the first magnetic attraction 2 and the second magnetic attraction 108. The positioning screw 10 can provide a pulling force to the bracket 5 to prevent the bracket 5 from being pulled out of the receiving cavity 901. When it is necessary to replace the battery cell 8 or the power board 6, the positioning screw 10 is removed. Then, the bracket 5, together with the battery cell 8 and the power board 6, can be removed from the receiving cavity 901 through the first buckle 505 and the first buckle hole 903, as well as the second buckle 506 and the second buckle hole 904.

[0027] In some embodiments, the top of the bracket 5 is provided with a first electrode post 3 and a second electrode post 4 as a conductive structure 1101. The power board 6 is electrically connected to the first electrode post 3 and the second electrode post 4. The bottom of the cartridge 1 is provided with a first contact 109 that abuts against the first electrode post 3 and a second contact 110 that abuts against the second electrode post 4.

The first electrode post 3 and the second electrode post 4, as well as the first contact body 109 and the second contact body 110, are all made of conductive copper. The good conductivity can reduce the power loss of the battery cell 8. The hard texture will not wear or deform after contact, which will lead to poor conductive contact. The air inlet 905 is used for air intake, and the air passage 507 is used to flow the air into the receiving cavity 901 to provide atomized airflow to the cartridge 1.

[0028] In some embodiments, an oil cavity 102 is formed inside the cartridge 1, an atomizing core 103 is provided inside the oil cavity 102, a mist channel 104 is formed inside the atomizing core 103, a heating core 105 electrically connected to the first electrical contact 109 and the second electrical contact 110 is provided inside the mist channel 104, an oil inlet hole 106 corresponding to the heating core 105 is opened on the outer wall of the atomizing core 103, an air guide channel 107 communicating with the mist channel 104 and the receiving cavity 901 is opened at the bottom end of the cartridge 1, and an exhaust channel 101 communicating with the mist channel 104 is opened at the top end of the cartridge 1.
