[0060] Please refer to Figures 1-4 、 Figures 6-8 and Figures 12-15 , an embodiment of the present application provides an electronic atomization device, which includes an atomization generating device 2 for generating aerosol and a power supply device 1 for supplying power to the atomization generating device 2, wherein:

[0061] The power supply device 1 includes a first housing 10, a power supply component 12 installed in the first housing 10, and a host electrode 13 electrically connected to the power supply component 12 (specifically, the power supply component 12 and the host electrode 13 can be electrically connected by means of a wire). One end of the first housing 10 in its height direction is provided with a nozzle 11, and the first housing 10 is provided with a receiving cavity 101 for receiving the aerosol generating device 2. The receiving cavity 101 penetrates the first housing 10 along the first direction of the first housing 10 and is communicated with the nozzle 11. The host electrode 13 is exposed on the cavity wall of the receiving cavity 101 facing the nozzle 11 (i.e., the lower side wall of the receiving cavity 101). The first direction of the first housing 10 is perpendicular to the height direction of the first housing 10. Illustratively, the first direction of the first housing 10 is Figure 2 , Figure 7 and Figure 14 the front-back direction in Figure 2 , Figure 7 and Figure 14 the up-down direction in

[0062] The aerosol generating device 2 includes a second housing 20, a first aerosol generator 21 for generating a first aerosol, and a second aerosol generator 22 for generating a second aerosol. The second housing 20 is installed in the receiving cavity 101 and is rotatably connected to the first housing 10. The second housing 20 can be rotated relative to the first housing 10 to a first position or a second position. And the second housing 20 has opposite first end 201 and second end 202 in its length direction (illustratively, the length direction of the second housing 20 is Figure 2 , Figure 7 and Figure 14 the up-down direction in

[0063] As Figure 3As shown, when the second housing 20 rotates relative to the first housing 10 to the first position, the first electrode assembly 211 is in electrical contact with the host electrode 13 and the first mist exhaust port 2011 is in communication with the mouthpiece 11. At this time, the first aerosol generator 21 operates due to being connected to the power supply assembly 12 and generates a first aerosol of one flavor. The first aerosol is discharged to the outside through the first mist exhaust port 2011 and the mouthpiece 11 for the user to inhale, so that the user can inhale the first aerosol of one flavor.

[0064] As Figure 4 shown, when the second housing 20 rotates relative to the first housing 10 to the second position, the second electrode assembly 221 is in electrical contact with the host electrode 13 and the second mist exhaust port 2021 is in communication with the mouthpiece 11. At this time, the second aerosol generator 22 operates due to being connected to the power supply assembly 12 and generates a second aerosol of another flavor. The second aerosol is discharged to the outside through the second mist exhaust port 2021 and the mouthpiece 11 for the user to inhale, so that the user can inhale the first aerosol of another flavor. Here, it can be understood that when the second housing 20 is in the first position, since the second electrode assembly 221 of the second aerosol generator 22 is not in contact with the host electrode 13 (that is, a closed circuit is not formed between the second aerosol generator 22 and the power supply assembly 12), the second aerosol generator 22 is in a stopped working state at this time. Similarly, when the second housing 20 is in the second position, since the first electrode assembly 211 of the first aerosol generator 21 is not in contact with the host electrode 13 (that is, a closed circuit is not formed between the first aerosol generator 21 and the power supply assembly 12), the first aerosol generator 21 is in a stopped working state at this time.

[0065] In the technical solution of this embodiment, since the aerosol generating device 2 includes a first aerosol generator 21 for generating a first aerosol and a second aerosol generator 22 for generating a second aerosol, and when the first housing 10 rotates to the first position, the first electrode assembly 211 of the first aerosol generator 21 can be in electrical contact with the main electrode 13 of the power supply device 1 to turn on the power supply assembly 12 of the power supply device 1. Therefore, the first aerosol generator 21 can be powered on to work and generate a first aerosol of one flavor (such as mint flavor). When the second housing 20 rotates to the second position, the second electrode assembly 221 of the second aerosol generator 22 can be in electrical contact with the main electrode 13 of the power supply device 1 to turn on the power supply assembly 12 of the power supply device 1. Therefore, the second aerosol generator 22 can be powered on to work and generate a second aerosol of another flavor (such as tobacco flavor). That is, the electronic atomization device provided in this embodiment can generate a first aerosol and a second aerosol with different flavors, so as to meet the user's demand for inhaling aerosols of different flavors. Moreover, when the user needs to change the flavor of the aerosol to be inhaled, the user only needs to rotate the position state of the aerosol generating device 2 from the first position to the second position or from the second position to the first position. That is, the user can switch the flavor by rotating the aerosol generating device 2, which is very convenient to operate, thus improving the user experience.

[0066] Please refer to Figures 3-4 、 Figure 8 and Figure 15 , in some alternative embodiments of the present application, an air intake passage 102 is provided in the first housing 10. The air intake passage 102 has an air intake hole 1021 and an air outlet hole 1022. The air intake hole 1021 is provided on the outer wall of the first housing 10, and the air outlet hole 1022 is provided on the wall of the receiving cavity 101 facing the mouthpiece 11. The first mist outlet 2011 is in communication with the second mist outlet 2021. Among them, when the second housing 20 rotates to the first position, the second mist outlet 2021 is in communication with the air outlet hole 1022; when the second housing 20 rotates to the second position, the first mist outlet 2011 is in communication with the air outlet hole 1022.

[0067] In this embodiment, based on the above structural design, when the user uses the electronic atomization device for suction, the user can smoothly inhale the aerosol of the desired flavor. Specifically, when the second housing 20 of the aerosol generating device 2 rotates to the first position and the user sucks at the mouthpiece 11, a suction airflow is formed on the airflow circulation path in which the air inlet hole 1021, the air outlet hole 1022, the second aerosol outlet 2021, the first aerosol outlet 2011, and the mouthpiece 11 are sequentially connected. The suction airflow will carry away the first aerosol generated when the first aerosol generator 21 is powered on and working. The first aerosol will finally be discharged to the outside from the mouthpiece 11 along with the suction airflow and be inhaled by the user; when the second housing 20 of the aerosol generating device 2 rotates to the second position and the user sucks at the mouthpiece 11, a suction airflow is formed on the airflow circulation path in which the air inlet hole 1021, the air outlet hole 1022, the first aerosol outlet 2011, the second aerosol outlet 2021, and the mouthpiece 11 are sequentially connected. The suction airflow will carry away the second aerosol generated when the second aerosol generator 22 is powered on and working. The second aerosol will finally be discharged to the outside from the mouthpiece 11 along with the suction airflow and be inhaled by the user.

[0068] Please continue to refer to Figures 3-4 、 Figure 8 and Figure 15 , in some alternative embodiments of the present application, the electronic atomization device further includes an airflow sensor 14 installed on the airflow circulation path of the air inlet passage 102. The power supply assembly 12 includes a battery 121 and a control circuit board 122 installed in the first housing 10. The control circuit board 122 is electrically connected to the battery 121, the airflow sensor 14, and the main body electrode 13 respectively. With such a setting, the electronic atomization device can work intelligently, thereby improving the user experience.

[0069] In this embodiment, specifically, please refer to Figure 3, when the second housing 20 of the aerosol generating device 2 rotates to the first position and the user sucks at the mouthpiece 11, a suction airflow will be formed on the airflow passage between the air inlet hole 1021 and the mouthpiece 11. When the suction airflow passes through the airflow sensor 14, the suction airflow will trigger the airflow sensor 14 to act, so that the airflow sensor 14 will send a suction signal indicating that the user is sucking to the control circuit board 122. When the control circuit board 122 receives this suction signal, the control circuit board 122 will control the first aerosol generator 21 to be powered on and work to generate a first aerosol of one flavor. The first aerosol will finally be discharged to the outside from the mouthpiece 11 together with the suction airflow and be inhaled by the user. When the user stops sucking, the suction airflow disappears, so that the airflow sensor 14 will send a stop signal indicating that the user stops sucking to the control circuit board 122. When the control circuit board 122 receives this stop signal, the control circuit board 122 will control the first aerosol generator 21 to be powered off and stop working.

[0070] Similarly, please refer to Figure 4 , when the second housing 20 of the aerosol generating device 2 rotates to the second position and the user sucks at the mouthpiece 11, a suction airflow will be formed on the airflow passage between the air inlet hole 1021 and the mouthpiece 11. When the suction airflow passes through the airflow sensor 14, the suction airflow will trigger the airflow sensor 14 to act, so that the airflow sensor 14 will send a suction signal indicating that the user is sucking to the control circuit board 122. When the control circuit board 122 receives this suction signal, the control circuit board 122 will control the second aerosol generator 22 to be powered on and work to generate a second aerosol of another flavor. The second aerosol will finally be discharged to the outside from the mouthpiece 11 together with the suction airflow and be inhaled by the user. When the user stops sucking, the suction airflow disappears, so that the airflow sensor 14 will send a stop signal indicating that the user stops sucking to the control circuit board 122. When the control circuit board 122 receives this stop signal, the control circuit board 122 will control the second aerosol generator 22 to be powered off and stop working.

[0071] Please refer to Figures 1-2 , Figures 6-7 and Figures 12-14 , in some optional embodiments of the present application, the shape and size of the aerosol generating device 2 are adapted to the shape and size of the receiving cavity 101. Illustratively, as Figures 1-2 and Figures 6-7As shown, the overall shape of the aerosol generating device 2 is generally a cuboid. The accommodation cavity 101 of the first housing 10 is generally a rectangular through hole. The length of the aerosol generating device 2 in the up-down direction is the same as or approximately the same as the length of the accommodation cavity 101 in the up-down direction. The width of the aerosol generating device 2 in the left-right direction is the same as or approximately the same as the width of the accommodation cavity 101 in the left-right direction. The height of the aerosol generating device 2 in the front-back direction is the same as or approximately the same as the depth of the accommodation cavity 101 in the front-back direction. Such a setting is conducive to improving the aesthetic appearance of the electronic atomization device. It should be noted here that the specific shape of the aerosol generating device 2 can be other shapes (such as a regular octagonal prism) in addition to a cuboid, and it can be determined according to actual usage requirements. This embodiment does not make specific restrictions on this.

[0072] Further, in some alternative embodiments of the present application, the second housing 20 of the aerosol generating device 2 and the first housing 10 of the power supply device 1 can be rotatably connected by setting a rotating shaft. Specifically, as Figures 2-4 , Figures 7-9 and Figures 14-15 shown, the electronic atomization device further includes a first rotating shaft 31 and a second rotating shaft 32. The accommodation cavity 101 has a first cavity wall 1041 and a second cavity wall 1051 that are relatively spaced apart in the second direction of the first housing 10. The second housing 20 and the first cavity wall 1041 of the first housing 10 are rotatably connected through the first rotating shaft 31 (specifically, one end of the first rotating shaft 31 can be fixed on the first cavity wall 1041 of the first housing 10, and the other end of the first rotating shaft 31 can be in clearance fit with the outer wall of the second housing 20 facing the first cavity wall 1041). The second housing 20 and the second cavity wall 1051 of the first housing 10 are rotatably connected through the second rotating shaft 32 (specifically, one end of the second rotating shaft 32 can be fixed on the second cavity wall 1051 of the first housing 10, and the other end of the second rotating shaft 32 can be in clearance fit with the outer wall of the second housing 20 facing the second cavity wall 1051). The second direction of the first housing 10 is perpendicular to the first direction of the first housing 10 and the height direction of the first housing 10. Illustratively, the second direction of the first housing 10 is the Figure 2 , Figure 7 and Figure 14 left-right direction in

[0073] Please refer to Figures 12-15, in some alternative embodiments of the present application, the first housing 10 includes a mounting portion 103, and a first support portion 104 and a second support portion 105 that are spaced apart from each other. The power supply assembly 12 is installed in the mounting portion 103. The first support portion 104 extends along the height direction of the first housing 10, and one end of the first support portion 104 is integrally connected to the mounting portion 103. The second support portion 105 extends along the height direction of the first housing 10, and one end of the second support portion 105 is integrally connected to the mounting portion 103. The first support portion 104, the second support portion 105, and the mounting portion 103 together define a receiving cavity 101 having a notch 1011. The first cavity wall 1041 is located on the first support portion 104, and the second cavity wall 1051 is located on the second support portion 105. The nozzle 11 is detachably sleeved at the notch 1011 of the receiving cavity 101 and wraps one end of the first support portion 104 away from the mounting portion 103, one end of the second support portion 105 away from the mounting portion 103, and one end of the second housing 20 away from the mounting portion 103.

[0074] In this embodiment, based on the above structural design, after the user completes the taste switching by rotating the aerosol generating device 2, under the limiting action of the mouthpiece 11, the aerosol generating device 2 can be stably held at the first position or the second position, preventing the aerosol generating device 2 from shaking violently and affecting the contact stability between the electrode assembly of the aerosol generating device 2 (i.e., the first electrode assembly 211 or the second electrode assembly 221) and the main body electrode 13 of the power supply device 1, thereby facilitating the improvement of the working stability of the electronic atomization device. Specifically, when the user needs to inhale the second aerosol generated by the second aerosol generator 22 and needs to rotate the entire aerosol generating device 2 from the first position to the second position, the user can first pull the mouthpiece 11 off the upper end of the first housing 10 by hand, and then push the first end 201 or the second end 202 of the first housing 10 by hand to rotate the entire aerosol generating device 2. When the entire aerosol generating device 2 rotates to the second position, the mouthpiece 11 is reinstalled on the upper end of the first housing 10 so that the mouthpiece 11 wraps around both the upper end of the first housing 10 and the second end 202 of the aerosol generating device 2. Since the second end 202 of the aerosol generating device 2 is restricted by the mouthpiece 11 at this time, even if the aerosol generating device 2 is pushed, the aerosol generating device 2 will not rotate, so that the aerosol generating device 2 can be stably held at the second position and is not prone to shaking. Similarly, when the user needs to inhale the first aerosol generated by the first aerosol generator 21 and needs to rotate the entire aerosol generating device 2 from the second position to the first position, the user can first pull the mouthpiece 11 off the upper end of the first housing 10 by hand, and then push the first end 201 or the second end 202 of the first housing 10 by hand to rotate the entire aerosol generating device 2. When the entire aerosol generating device 2 rotates to the first position, the mouthpiece 11 is reinstalled on the upper end of the first housing 10 so that the mouthpiece 11 wraps around both the upper end of the first housing 10 and the first end 201 of the aerosol generating device 2. Since the first end 201 of the aerosol generating device 2 is restricted by the mouthpiece 11 at this time, even if the aerosol generating device 2 is pushed, the aerosol generating device 2 will not rotate, so that the aerosol generating device 2 can be stably held at the first position and is not prone to shaking.

[0075] Please refer to Figures 2-5 、 Figures 7-11 and Figures 14-15, in some alternative embodiments of the present application, at least one first magnetic member 15 is provided on the cavity wall of the receiving cavity 101, and at least one second magnetic member 23 is provided on the outer wall of the aerosol generating device 2. When the second housing 20 rotates to the first position or the second position, at least one first magnetic member 15 and at least one second magnetic member 23 attract each other. In this way, by using the attraction force between the first magnetic member 15 and the second magnetic member 23, after the user completes the taste switching by rotating the aerosol generating device 2, the aerosol generating device 2 can be stably held at the first position or the second position, avoiding violent shaking of the aerosol generating device 2 and affecting the contact stability between the electrode assembly of the aerosol generating device 2 (i.e., the first electrode assembly 211 or the second electrode assembly 221) and the main electrode 13 of the power supply device 1, thereby facilitating the improvement of the working stability of the electronic atomization device.

[0076] In this embodiment, it should be noted that in specific implementation, in some alternative embodiments, the first magnetic member 15 can be a magnet embedded in the cavity wall of the receiving cavity 101, and the second magnetic member 23 can be a magnet embedded in the outer wall of the second housing 20, and the polarity of the exposed end of the first magnetic member 15 is opposite to the polarity of the exposed end of the second magnetic member 23; in other alternative embodiments, one of the first magnetic member 15 and the second magnetic member 23 is a magnet, and the other is a magnetic conductor made of a magnetic conductive material (such as magnetic conductive materials of iron, nickel-chromium-iron alloy, silicon steel, etc.), as long as the use requirements can be met. The present embodiment does not specifically limit the structural forms of the first magnetic member 15 and the second magnetic member 23. In addition, the number of the first magnetic members 15 and the number of the second magnetic members 23 can be one or multiple, and they can be flexibly set according to actual use needs. The present embodiment also does not specifically limit the number of the first magnetic members 15 and the second magnetic members 23. Additionally, the first magnetic member 15 can be provided on the upper side wall of the receiving cavity 101, or on the lower side wall of the receiving cavity 101, or on the left side wall or the right side wall of the receiving cavity 101. Correspondingly, the second magnetic member 23 can be provided on the upper side wall of the aerosol generating device 2, or on the lower side wall of the aerosol generating device 2, or on the left side wall or the right side wall of the aerosol generating device 2, as long as the use requirements can be met. The present embodiment also does not specifically limit the specific installation positions of the first magnetic member 15 and the second magnetic member 23.

[0077] Please refer to Figures 2-5 , Figures 7-11 and Figures 13-15, in some alternative embodiments of the present application, the first electrode assembly 211 includes at least two first fixed electrodes 2110 arranged at intervals, the second electrode assembly 221 includes at least two second fixed electrodes 2210 arranged at intervals, and the host electrode 13 includes at least two elastic electrodes 131 arranged at intervals. Wherein, when the second housing 20 rotates to the first position, at least two first fixed electrodes 2110 are in one-to-one electrical contact with at least two elastic electrodes 131; when the second housing 20 rotates to the second position, at least two second fixed electrodes 2210 are in one-to-one electrical contact with at least two elastic electrodes 131. It can be understood here that in some specific application scenarios, the two first fixed electrodes 2110 can serve as the positive and negative electrodes of the first aerosol generator 21 respectively, the two second fixed electrodes 2210 can serve as the positive and negative electrodes of the second aerosol generator 22 respectively, and the two elastic electrodes 131 can serve as the positive and negative electrodes of the power supply device 1 respectively.

[0078] In this embodiment, based on the above structural design, by designing both the positive and negative electrodes of the host electrode 13 as elastic electrodes 131 and designing the positive and negative electrodes of the first electrode assembly 211 and the second electrode assembly 221 as fixed electrodes. Thus, on the one hand, during the process of rotating the entire aerosol generating device 2 from the first position to the second position (or from the second position to the first position), since the host electrode 13 with the structural form of an elastic electrode 131 will be squeezed by the first end portion 201 (or the second end portion 202) of the aerosol generating device 2 and automatically contract, even if the host electrode 13 protrudes from the lower side wall of the receiving cavity 101, the host electrode 13 will not cause substantial obstruction to the rotation of the aerosol generating device 2, so that the aerosol generating device 2 can normally rotate from the first position to the second position (or from the second position to the first position); on the other hand, after the aerosol generating device 2 rotates to the second position (or the first position), since the host electrode 13 is in a compressed state, the host electrode 13 will generate a rebounding force towards the aerosol generating device 2. Under the action of this rebounding force, the host electrode 13 can always maintain close contact with the second electrode assembly 221 (or the first electrode assembly 211), thereby improving the reliability of the electrical contact between the second electrode assembly 221 (or the first electrode assembly 211) and the host electrode 13, which is beneficial to further improving the working stability of the electronic atomization device.

[0079] In this embodiment, it should be noted that a fixed electrode is a type of electrode that cannot perform elastic expansion and contraction, and the elastic electrode 131 is a type of electrode that can perform elastic expansion and contraction along its own axis. Their specific structures are well-known to those skilled in the art and will not be elaborated here.

[0080] Please refer to Figures 3-5 and Figures 7-11, in some alternative embodiments of the present application, at least two first electrode mounting holes 2012 are formed on the end surface of the first end portion 201, at least two second electrode mounting holes 2022 are formed on the end surface of the second end portion 202, at least two first fixed electrodes 2110 are fixedly mounted in the at least two second electrode mounting holes 2022 in a one-to-one correspondence, at least two second fixed electrodes 2210 are fixedly mounted in the at least two first electrode mounting holes 2012 in a one-to-one correspondence, and the end surface of each exposed end of the elastic electrode 131 is an arc surface. Wherein, when the second housing 20 rotates to the first position, the corresponding elastic electrode 131 is snapped into the corresponding second electrode mounting hole 2022 and is in electrical contact with the corresponding first fixed electrode 2110; when the second housing 20 rotates to the second position, the corresponding elastic electrode 131 is snapped into the corresponding first electrode mounting hole 2012 and is in electrical contact with the corresponding second fixed electrode 2210.

[0081] In this embodiment, based on the above structural design, since the upper end surface of each elastic electrode 131 is an arc surface, a sliding contact can be formed between the first end portion 201 (or the second end portion 202) of the aerosol generating device 2 and the upper ends of the respective elastic electrodes 131. Furthermore, during the process of applying a force to push the entire aerosol generating device 2 to rotate from the first position to the second position (or from the second position to the first position), each elastic electrode 131 can be more easily compressed, so that the aerosol generating device 2 can rotate to the second position (or the first position) more smoothly and the main body electrode 13 and the second electrode assembly 221 (or the first electrode assembly 211) can maintain close contact; moreover, at the moment when the elastic electrode 131 is snapped into the second electrode mounting hole 2022 (or the first electrode mounting hole 2012), the upper end of the elastic electrode 131 will make a certain degree of impact sound due to hitting the second fixed electrode 2210, thereby bringing a certain degree of auditory feedback or tactile feedback to the user, enabling the user to clearly perceive that the aerosol generating device 2 has rotated to the second position (or the first position), and thus improving the user experience; in addition, after the elastic electrode 131 is snapped into the second electrode mounting hole 2022 (or the first electrode mounting hole 2012), due to a certain degree of engagement between the elastic electrode 131 and the second electrode mounting hole 2022 (or the first electrode mounting hole 2012), compared with pushing the first end portion 201 (or the second end portion 202) of the aerosol generating device 2 into the receiving cavity 101, the user needs to apply more force to push the first end portion 201 (or the second end portion 202) of the aerosol generating device 2 out of the receiving cavity 101. That is to say, the elastic electrode 131 can also play a certain limiting role, so that after the aerosol generating device 2 is rotated to the second position (or the first position), the aerosol generating device 2 is less likely to shake.

[0082] In some alternative embodiments of the present application, the specific structural form of the aerosol generating device 2 may be as follows:

[0083] Specifically, as Figures 3-5 and Figure 15 shown, a first storage cavity 212 for storing the first aerosol forming matrix and a first air passage 213 communicating with the first mist outlet 2011 are provided in the second end portion 202 of the second housing 20. The first aerosol generator 21 includes a first atomization core 214 electrically connected to the first electrode assembly 211 (specifically, the first electrode assembly 211 and the first atomization core 214 can be electrically connected by means of a wire). The first atomization core 214 is installed on the airflow passage of the first air passage 213 so that the aerosol generated by the subsequent first atomization core 214 can be carried away by the suction airflow flowing through the first air passage 213. Moreover, the first atomization core 214 communicates with the first storage cavity 212 so that the first atomization core 214 can suck the first aerosol forming matrix from the first storage by means of capillary action. Among them, the first aerosol forming matrix may be a liquid substance (such as e-liquid or liquid medicine) with a certain flavor (such as mint flavor). The type of the first aerosol forming matrix can be determined according to actual usage requirements, and this embodiment does not make specific limitations on this;

[0084] A second storage cavity 222 for storing the second aerosol forming matrix and a second air passage 223 communicating with the second mist outlet 2021 are provided in the first end portion 201 of the second housing 20. The second storage cavity 222 is arranged separately from the first storage cavity 212. The second aerosol generator 22 includes a second atomization core 224 electrically connected to the second electrode assembly 221 (specifically, the second electrode assembly 221 and the second atomization core 224 can be electrically connected by means of a wire). The second atomization core 224 is installed on the airflow passage of the second air passage 223 so that the aerosol generated by the subsequent second atomization core 224 can be carried away by the suction airflow flowing through the second air passage 223. Moreover, the second atomization core 224 communicates with the second storage cavity 222 so that the second atomization core 224 can suck the second aerosol forming matrix from the second storage by means of capillary action. Among them, the second aerosol forming matrix may be a liquid substance (such as e-liquid or liquid medicine) with a certain flavor (such as tobacco flavor). The type of the second aerosol forming matrix can be determined according to actual usage requirements, and this embodiment does not make specific limitations on this.

[0085] In this embodiment, based on the above structural design, as Figure 3As shown in the figure, when the second housing 20 rotates to the first position, the first atomization core 214 is powered on through the first electrode assembly 211 and the main body electrode 13 to connect to the power supply assembly 12. The first atomization core 214 is energized and heated to atomize the first aerosol-forming matrix it absorbs into a first aerosol with a certain flavor. The first aerosol is discharged to the outside through the first exhaust port 2011 and the mouthpiece 11 for the user to inhale; as Figure 4 shown in the figure, when the second housing 20 rotates to the second position, the second atomization core 224 is powered on through the second electrode assembly 221 and the main body electrode 13 to connect to the power supply assembly 12. The second atomization core 224 is energized and heated to atomize the second aerosol-forming matrix it absorbs into a second aerosol with a certain flavor. The second aerosol is discharged to the outside through the second exhaust port 2021 and the mouthpiece 11 for the user to inhale.

[0086] In this embodiment, it should be noted that the specific structural form and working principle of the first atomization core 214, the specific structural form and working principle of the second atomization core 224, the way of realizing communication between the first atomization core 214 and the first storage cavity 212, and the way of realizing communication between the second atomization core 224 and the second storage cavity 222 are well known to those skilled in the art and will not be elaborated here.

[0087] In some other alternative embodiments of the present application, the specific structural form of the aerosol generating device 2 may also be as follows:

[0088] Specifically, as Figures 8-11 shown in the figure, a first accommodation cavity 203 for accommodating the first aerosol generator 21 is provided in the second end portion 202, a second accommodation cavity 204 for accommodating the second aerosol generator 22 is provided in the first end portion 201, a partition 205 is provided between the first accommodation cavity 203 and the second accommodation cavity 204, and a ventilation hole 2051 is opened on the partition 205;

[0089] The first aerosol generator 21 includes a first housing assembly 215 and a first atomization core 214. A first air passage 213 and a first storage cavity 212 for storing the first aerosol-forming matrix are provided inside the first housing assembly 215. The first housing assembly 215 is detachably installed in the first accommodation cavity 203 and one end of the first air passage 213 is communicated with the ventilation hole 2051. The end face of the first housing assembly 215 facing away from the partition 205 is the end face of the second end portion 202. The first atomization core 214 is installed on the airflow path of the first air passage 213 and is communicated with the first storage cavity 212. The first electrode assembly 211 is electrically connected to the first atomization core 214, and the second exhaust port 2021 is communicated with the end of the first air passage 213 far from the ventilation hole 2051;

[0090] The second aerosol generator 22 includes a second housing assembly 225 and a second atomization core 224. A second air passage 223 and a second storage cavity 222 for storing the second aerosol formation matrix are provided inside the second housing assembly 225. The second housing assembly 225 is detachably mounted in the second accommodation cavity 204, and one end of the second air passage 223 communicates with the ventilation hole 2051. The end face of the second housing assembly 225 facing away from the partition 205 is the end face of the first end portion 201. The second atomization core 224 is installed on the airflow path of the second air passage 223 and communicates with the second storage cavity 222. The second electrode assembly 221 is electrically connected to the second atomization core 224. The second mist outlet 2021 communicates with the end of the second air passage 223 away from the ventilation hole 2051.

[0091] In this embodiment, it can be understood that the electronic atomization device provided in this embodiment (as Figures 6-11 shown) is different from the electronic atomization device provided in the embodiment as Figures 1-5 , Figures 12-15 shown in that in the electronic atomization device provided in this embodiment, the first aerosol generator 21 and the second aerosol generator 22 can be replaced. Specifically, after the first aerosol formation matrix in the first aerosol generator 21 and the second aerosol formation matrix in the second aerosol generator 22 are consumed, the aerosol generating device 2 can be rotated to a position state where both the first end portion 201 and the second end portion 202 of the second housing 20 are out of the receiving cavity 101. Then, the used first aerosol generator 21 and second aerosol generator 22 are removed from the second housing 20. Immediately afterwards, a new first aerosol generator 21 is installed in the first accommodation cavity 203 of the second housing 20 and a new second aerosol generator 22 is installed in the second accommodation cavity 204 of the second housing 20. Finally, the aerosol generating device 2 is rotated to the first position or the second position. In this way, the electronic atomization device can continue to be used to inhale the aerosol of the desired flavor. That is to say, it is equivalent to that the second housing 20 and the entire power supply device 1 can be reused, which is beneficial to reducing the user's usage cost and improving the environmental protection performance of the electronic atomization device. Among them, in specific implementation, the structural compositions, shapes and sizes of the first aerosol generator 21 and the second aerosol generator 22 can be exactly the same, so that both the first accommodation cavity 203 and the second accommodation cavity 204 can be adapted to the first aerosol generator 21 and the second aerosol generator 22, which is beneficial to improving the replacement efficiency of the first aerosol generator 21 and the second aerosol generator 22, and is also beneficial to the mass production of the first aerosol generator 21 and the second aerosol generator 22.

[0092] Further, please continue to refer to Figures 8-11, in some alternative embodiments of the present application, the detachable connection between the first aerosol generator 21 and the second housing 20, and between the second aerosol generator 22 and the second housing 20 can be achieved by magnetic attraction.
