[0045] In one embodiment, please refer to Figures 1 to 7 The aerosol generating device comprises a main unit and an atomizer 1 for heating and atomizing an aerosol generating substrate to generate an aerosol. The main unit comprises a power supply unit, a shell component 4 and a locking structure 22. The power supply unit supplies power to the atomizer 1. The locking structure 22 is used to act on the power supply unit to lock the power supply unit with the shell component.

[0046] The power supply unit includes a power supply 3 and a controller, and the power supply 3 outputs voltage and current in response to a control signal output by the controller. The housing assembly 4 includes a cylindrical housing 41 and a bottom cover 42 connected to a first end 4101 of the cylindrical housing 41, and a second end 4102 of the cylindrical housing 41 has a second port 411 for loading or unloading the power supply unit. The locking structure 22 is used to lock the power supply unit with the cylindrical housing 41, or to lock the power supply unit with the bottom cover 42, so as to limit the displacement of the power supply unit relative to the cylindrical housing 41.

[0047] The power supply unit can be installed into the shell assembly 4 through the second port 411. After installation, the power supply unit is locked by the locking structure 22 to limit the movement of the power supply unit, so that the reliability of the power supply unit is better.

[0048] Regarding the atomizer 1, the atomizer 1 has a nozzle 11 at the top, and the nozzle 11 is used to inhale the aerosol generated by the atomizer 1. In the present application, the atomizer 1 can use an aerosol generating rod, and the aerosol generating rod is heated to generate aerosol, and can also use an aerosol generating oil, and the aerosol generating oil is heated and atomized to generate aerosol.

[0049] In one embodiment, please refer to Figure 2 and Figure 3 The aerosol generating device is a disposable aerosol generating device, and the atomizer 1 has an oil storage tank for storing aerosol generating oil. The atomizer 1 includes an electric heating element 12, and the power supply 3 supplies power to the electric heating element 12, and the electric heating element 12 is used to heat the aerosol generating oil to generate aerosol. In one embodiment, the power supply 3 is a battery.

[0050] Any feasible atomizer 1 in the prior art can be used in this application. Since the atomizer 1 in this application is a mature existing structure, this application only briefly introduces it. Figure 2 and Figure 3The atomizer 1 includes an atomizer shell 13 and an atomizer upper cover 14. The suction nozzle 11 is installed on the atomizer upper cover 14, and there is an oil-absorbing cotton 16 between the suction nozzle 11 and the atomizer upper cover 14. The atomizer shell 13 includes an oil storage bin, oil storage cotton 17 in the oil storage bin, and an atomizing assembly 18. The atomizing assembly 18 includes an electric heating element 12. The aerosol-generating oil in the oil storage bin is heated and atomized to generate aerosol after reaching the position of the electric heating element 12.

[0051] Regarding the shell component 4, in one embodiment, please refer to Figure 2 and Figure 3 The shell 41 has an atomizer installation space for loading the atomizer 1, and the power supply unit has a fixed connection structure for fixedly connecting with the atomizer 1 of the aerosol generating device. In this way, the power supply unit can be fixed to the atomizer 1 and then installed in the shell 41 as a whole, so that the atomizer 1 and the power supply unit can be assembled as separate modules into a combined module, and then assembled as a whole with the shell 41, which simplifies the assembly process. In one embodiment, please refer to Figure 2 and Figure 3 The atomizer installation space is located on the side of the power supply unit facing the second port 411 .

[0052] In some other embodiments, the shell assembly 4 can be used only to install the power supply unit, and the atomizer 1 comes with the atomizer 1 shell. In this case, after the host is connected to the atomizer 1, the atomizer 1 is outside the barrel shell 41. In some other embodiments, the atomizer 1 and the power supply unit can also be installed in the barrel shell 41 respectively.

[0053] In one embodiment, please refer to Figure 2 and Figure 3 The power supply unit includes a power supply bracket 2, and the power supply 3 is configured on the power supply bracket 2. The locking structure 22 is at least partially configured on the power supply bracket 2, and the locking structure 22 is used to lock the power supply bracket 2 and the cylinder shell 41. It should be noted that the locking structure 22 can be configured only on the power supply bracket 2, can also be configured on the cylinder shell 4, and can also be partially configured on the cylinder shell 4 and partially configured on the power supply bracket 2.

[0054] In order to facilitate assembly and disassembly, the power supply bracket 2 is connected to the bottom of the atomizer 1. The power supply bracket 2 and the atomizer 1 can be connected in any feasible manner, including bonding, welding, snap connection, or fixed connection by fasteners.

[0055] In one embodiment, please refer to Figure 3 , the second port 411 is located at the top of the cylinder shell 41. The mouthpiece 11 is exposed from the shell assembly 4, and is provided for the user to inhale the aerosol generated by the aerosol generating device.

[0056] Please refer to Figure 2 , Figure 4 and Fig.11 , the locking structure 22 is locked with the cylindrical shell 41 after the power supply bracket 2 is installed into the shell assembly 4, and the power supply bracket 2 is restricted from leaving the shell assembly 4. In order to facilitate the disassembly of the power supply 3, the bottom cover 42 is movably arranged at the first end 4101 of the cylindrical shell 41, and the bottom cover 42 has a first position and a second position relative to the cylindrical shell 41. When the bottom cover 42 is in the second position, the bottom cover 42 causes the locking structure 22 to unlock the cylindrical shell 41. When the bottom cover 42 is in the first position, the locking structure 22 is locked with the cylindrical shell 41.

[0057] When the power source 3 needs to be recovered, the bottom cover 42 is pressed so that the bottom cover 42 pushes the power supply unit, and the locking structure 22 and the cylinder shell 41 are unlocked. After unlocking, the power supply unit can be pulled out from the second port 411, and then the power source 3 can be recovered, thereby improving the current technical problems of difficult disassembly of the aerosol generating device and inconvenient recovery of the power source 3.

[0058] Specifically, in one embodiment, please refer to Figure 2 , Figure 3 , Fig.10 and Fig.11 The bottom cover 42 has a push portion 421, which is used to push the power supply unit or the locking structure 22 when the bottom cover 42 is pressed from the first position to the second position, so that the power supply unit is unlocked from the cylinder shell 41. Unlocking the locking structure 22 by pressing the bottom cover 42 is simple and convenient.

[0059] Further, in one embodiment, please refer to Figure 2 and Figure 3 In order to facilitate unlocking the locking structure 22, the pushing portion 421 pushes the locking structure 22 to elastically deform the locking structure 22 and then unlocks it from the cylinder shell 41. The locking structure 22 is located at the bottom of the power supply bracket 2, and the pushing portion 421 of the bottom cover 42 directly acts on the locking structure 22, making unlocking more convenient and effective, and less prone to failure. The bottom space of the power supply bracket 2 is large, which is also convenient for the arrangement of the locking structure 22.

[0060] In some other embodiments, in addition to elastically deforming the locking structure 22 to unlock the locking structure 22, a mechanical locking structure may also be used. For example, the locking structure 22 includes a hook movably connected to the power supply bracket 2 and an elastic member that applies elastic force to the hook. The elastic member applies force to the hook so that the hook always hooks the cylinder shell 41 to keep the locking structure 22 in a locked state. When unlocking is required, the pushing portion 421 pushes the lock hook to separate the lock hook from the cylinder shell 41, thereby completing the unlocking of the locking structure 22.

[0061] In one embodiment, please refer to Figure 3 , Figure 5 and Figure 6In order to facilitate unlocking, the locking structure 22 includes a bracket locking arm 221 extending up and down and a bracket locking buckle 222 at the lower end of the bracket locking arm 221. The bottom of the cylinder shell 41 has a locking buckle adapting structure locked with the bracket locking buckle 222. The pushing portion 421 is used to push the bottom of the bracket locking buckle 222 so that the bracket locking arm 221 is deformed and unlocked from the cylinder shell 41. By arranging the bracket locking buckle 222 at the lower end of the bracket locking arm 221, the bracket locking buckle 222 is easier to deform, and less force is required during the unlocking operation.

[0062] Further, in one embodiment, please refer to Figure 7 The number of the bracket locking arms 221 is at least two, and each bracket locking arm 221 is arranged at intervals in the circumferential direction of the cylinder shell 41, and each bracket locking arm 221 is provided with a bracket locking buckle 222. The number of the bracket locking arms 221 is at least two, so that the power supply bracket 2 and the cylinder shell 41 can be locked at at least two positions in the circumferential direction of the cylinder shell 41, and the stability is better. In some other embodiments, only one bracket locking arm 221 can be provided.

[0063] Specifically, in one embodiment, please refer to Figure 7 The number of the bracket locking arms 221 is two, the two bracket locking arms 221 are arranged opposite to each other, and the cross-sections of the bracket locking arms 221 are both arc-shaped. In some other embodiments, the cross-sections of the bracket locking arms 221 can be any feasible shapes such as circular, square, etc. as needed.

[0064] In one embodiment, please refer to Figure 7 The number of the lock buckle adapter structures is at least two, and the lock buckle adapter structure corresponds to at least one bracket lock buckle 222 on the bracket lock arm 221. When there are more than two lock buckle adapter structures, the locking stability of the power supply bracket 2 and the cylinder shell 41 is better.

[0065] Regarding the lock adapter structure, in one embodiment, please refer to Figure 7 The lock buckle matching structure includes a lock hook 414 in the cylinder shell 41, and the bracket lock buckle 222 is locked after being hooked with the lock hook 414. In some other embodiments, the lock buckle matching structure can also be a lock hole in the cylinder shell 41, and the lock buckle is locked in the lock hole to achieve locking.

[0066] Specifically, when the bracket lock 222 and the lock hook 414 are locked, the bracket lock 222 is inserted downward into the cartridge shell 41, and the upper side surface 4141 and the lower side surface 4142 of the lock hook are both inclined surfaces. The bracket lock 222 first contacts the upper side surface 4141 of the lock hook, and after pressing down the atomizer 1 and the power supply bracket 2, under the guidance of the upper side surface 4141 of the lock hook, the bracket locking arm 221 is deformed until the upper side surface 2221 of the lock hook is hooked with the lower side surface 4142 of the lock hook, thereby completing the locking of the lock and the lock hook 414.

[0067] Please note that, please refer to Figure 3 and Figure 7 The upper side 2221 of the lock buckle is an inclined surface, and the lower side 2222 of the lock buckle is also an inclined surface. In this way, when the pushing portion 421 on the bottom cover 42 pushes the lock buckle to unlock, the upper side 2221 of the lock buckle contacts the lower side 4142 of the lock hook, guiding the bracket locking arm 221 to deform, so that the bracket lock buckle 222 is separated from the lock hook 414.

[0068] In some other embodiments, the upper side 2221 of the lock buckle and the lower side 2222 of the lock buckle are both inclined surfaces, and the upper side 4141 of the lock hook and the lower side 4142 of the lock hook can also be planes perpendicular to the axis of the cylinder shell 41. In some other embodiments, the upper side 2221 of the lock buckle and the lower side 2222 of the lock buckle can also be planes perpendicular to the axis of the cylinder shell 41, and the upper side 4141 of the lock hook and the lower side 4142 of the lock hook are both planes.

[0069] In one embodiment, please refer to Figure 3 and Figure 7 The locking structure 22 is configured on the power supply unit, and the locking structure 22 includes a locking guide protrusion 223. The cylinder shell 41 has a guide slope 412 facing the second port 411. When the locking structure 22 is installed into the cylinder shell 41 along with the power supply unit, the guide slope 412 and the locking guide protrusion 223 are slidably matched to guide the locking structure 22 to lock the power supply unit with the cylinder shell 41. Specifically, in one embodiment, please refer to Figure 3 and Figure 7 In order to lock the bracket lock buckle 222 on the bracket lock arm 221 with the corresponding lock buckle matching structure, the bracket lock arm 221 is provided with a locking guide protrusion 223, and the cylinder shell 41 has a guide slope 412 facing the second port 411 (see Figure 7 ), when the power supply bracket 2 is installed into the cartridge case 41, the guide slope 412 and the locking guide protrusion 223 are slidably matched to guide the power supply bracket 2 to rotate to a suitable angle, so that the bracket lock 222 on the bracket locking arm 221 is locked with the corresponding lock adapter structure. In this way, when the power supply bracket 2 and the atomizer 1 are installed, under the guidance of the locking guide protrusion 223, it is more convenient to lock the power supply bracket 2 and the cartridge case 41, which is conducive to improving the assembly efficiency.

[0070] Further, in one embodiment, please refer to Figure 3 and Figure 7 The bottom of the cylinder shell 41 has a rotation-stop groove 413, and the locking guide protrusion 223 is inserted into the rotation-stop groove 413 after the locking structure 22 locks the power supply unit and the cylinder shell 41, preventing the power supply unit from rotating. The locking guide protrusion 223 cooperates with the rotation-stop groove 413 to make the cylinder shell 41 and the power supply bracket 2 more stable and not easy to shake.

[0071] In one embodiment, please refer to Figure 6 and Figure 7 The locking guide protrusion 223 is a long strip protrusion extending up and down, and the locking guide protrusion 223 is arranged on the bracket locking arm 221. In one embodiment, the locking guide protrusion 223 is located between two bracket lock buckles 222, and the two bracket lock buckles 222 are connected together through the locking guide protrusion 223. Specifically, the number of the locking hooks 414 and the number of the bracket lock buckles 222 are both four, and the anti-rotation groove 413 is located between the two locking hooks 414.

[0072] In one embodiment, please refer to Figure 2 The bottom of the cylinder shell 41 has a bottom cover movable hole 415, which can guide the bottom cover 42 to move along the extension direction of the cylinder shell 41. The guiding effect of the bottom cover movable hole 415 can make the bottom cover 42 run more stably when the bottom cover 42 is pressed, and it is not easy to deflect and get stuck.

[0073] In one embodiment, the bottom cover 42 has a bottom cover stop structure. Before the bottom cover 42 is pressed to push the power supply bracket 2, the bottom cover stop structure and the cylinder shell 41 are blocked to prevent the bottom cover 42 from moving away from the power supply bracket 3. Figure 3 and Figure 5 The bottom cover anti-retraction structure includes an anti-retraction hook 422, and the bottom of the cylinder shell 41 has a hook matching groove or a hook matching hole 416, and at least a part of the anti-retraction hook 422 is in the hook matching groove or the hook matching hole 416. The anti-retraction hook 422 can better prevent the bottom cover 42 from leaving the cylinder shell 41.

[0074] Specifically, in one embodiment, please refer to Figure 3 and Figure 5 The bottom cover 42 includes a cover body 423 and a bottom cover locking arm 424 located on the side of the cover body 423 facing the power supply bracket 2, and the anti-retraction hook 422 is located at the end of the bottom cover locking arm 424 away from the cover body 423. When the bottom cover 42 is installed, the bottom cover locking arm 424 can be deformed so that the anti-retraction hook 422 can be installed from the lower end of the bottom cover movable hole 415. In order to prevent the bottom cover 42 from falling off, the lower side of the anti-retraction hook 422 facing the cover body 423 is a plane perpendicular to the center line of the cylinder shell 41, and the upper side of the anti-retraction hook 422 is an inclined surface, which is used to guide the deformation of the bottom cover locking arm 424 when the bottom cover is installed into the cylinder shell 41.

[0075] Specifically, in one embodiment, please refer to Figure 3 and Figure 5 There are two bottom cover locking arms 424 , which are arranged opposite to each other.
