[0058] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the embodiment of the present application provides an atomizer 100, which comprises a shell 1, a suction nozzle 3 and a conversion mechanism 4.

[0059] The shell 1 is internally provided with a plurality of cartridges 2, each of which has an aerosol passage 521 for guiding airflow to pass through and an aerosol outlet 22 for outputting aerosol.

[0060] The suction nozzle 3 is connected to one end of the shell 1 close to the aerosol outlet 22.

[0061] The conversion mechanism 4 is arranged between the shell 1 and the suction nozzle 3, and a plurality of passages 5 are arranged on the conversion mechanism 4 and communicated with the suction nozzle 3.

[0062] The conversion mechanism 4 is configured to be able to be operated by the user to rotate relative to the shell 1, and at least includes a first state and a second state in the rotation process. When the conversion mechanism 4 is in the first state, only one of the aerosol outlets 22 of the cartridges 2 is communicated with the mouthpiece 3 through the channel 5. When the conversion mechanism 4 is in the second state, the aerosol outlets 22 of at least two cartridges 2 are simultaneously communicated with the mouthpiece 3 through the channel 5, so as to combine the airflow in the aerosol channels 521 of the at least two cartridges 2 into the mouthpiece 3. When the user rotates the conversion mechanism 4, the conversion mechanism 4 can rotate relative to the shell 1, and in the rotation process, the communication between the channel 5 and the aerosol outlet 22 is realized, and the first state and the second state are presented. When the conversion mechanism 4 is in the first state, the channel 5 thereon only communicates the aerosol outlet 22 of one cartridge 2 with the mouthpiece 3, that is, only the aerosol generated in one cartridge 2 is output from the aerosol outlet 22 to the mouthpiece 3. When the conversion mechanism 4 is in the second state, the channel 5 thereon can simultaneously communicate at least two aerosol outlets 22 with the mouthpiece 3, that is, the aerosols generated in at least two cartridges 2 are simultaneously output from the aerosol outlets 22 to the mouthpiece 3. Thus, the conversion between the first state and the second state can be realized by rotating the conversion mechanism 4, and the user can realize the switching of different cartridge 2 flavors on one atomizer 100, providing rich smoking flavors for the user to choose, that is, the aerosol generated by different single cartridges 2 can be smoked, and the mixed aerosol generated by cartridges 2 of multiple flavors can also be smoked.

[0063] In some embodiments, the housing 1 can be provided with two cartridges 2, or three cartridges 2, or four cartridges 2, or more cartridges 2. The types or compositions of the liquid substrate carried in different cartridges 2 can be the same, or different, for example, the liquid substrate in different cartridges 2 has different types of flavorings or different concentration ratios of flavorings, including sweeteners, cooling agents or fruit flavor ingredients. For example, the liquid substrate in different cartridges includes different content ratios of nicotine salts. For example, the housing 1 is provided with a first cartridge, a second cartridge, a third cartridge and a fourth cartridge, four cartridges 2, which can be distributed around a central axis. The first state of the conversion mechanism 4 can be that the passage 5 therein only connects the aerosol outlet 22 of the first cartridge, the second cartridge, the third cartridge or the fourth cartridge to the mouthpiece 3, that is, only the aerosol generated in the first cartridge, the second cartridge, the third cartridge or the fourth cartridge is output from the aerosol outlet 22 of the cartridge 2 to the mouthpiece 3. The second state of the conversion mechanism 4 can be that the passage 5 therein simultaneously connects the aerosol outlets 22 of the first cartridge and the second cartridge to the mouthpiece 3; or the second state of the conversion mechanism 4 can be that the passage 5 therein simultaneously connects the aerosol outlets 22 of the second cartridge and the third cartridge to the mouthpiece 3; or the second state of the conversion mechanism 4 can be that the passage 5 therein simultaneously connects the aerosol outlets 22 of the third cartridge and the fourth cartridge to the mouthpiece 3; or the second state of the conversion mechanism 4 can be that the passage 5 therein can simultaneously connect the aerosol outlets 22 of the fourth cartridge and the first cartridge to the mouthpiece 3. Alternatively, the second state of the conversion mechanism 4 can be that the passage 5 therein simultaneously connects any three aerosol outlets 22 of the four cartridges 2 to the mouthpiece 3. Alternatively, the second state of the conversion mechanism 4 can be that the passage 5 therein simultaneously connects the aerosol outlets 22 of all cartridges 2 to the mouthpiece 3.

[0064] In some embodiments, one end of the mouthpiece 3 towards the housing 1 can be provided with a through hole, and the housing 1 is provided with a fixing hole 12 corresponding to the through hole, and the atomizer 100 is further provided with a fastener 6, after the housing 1, the conversion mechanism 4 and the mouthpiece 3 are assembled, the fastener 6 can pass through the fixing hole 12 of the housing 1 and the through hole of the mouthpiece 3 in sequence, and the mouthpiece 3 is fixed to the housing 1, and the conversion mechanism 4 is fixed between the mouthpiece 3 and the housing 1.

[0065] In some embodiments, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4The switching mechanism 4 is configured to be able to switch the first state and the second state alternately in the rotation process, so that the user can switch different cartridges 2 in communication with the mouthpiece 3 by rotating the switching mechanism 4, and realize the switching of different flavors of cartridges 2. For example, the inside of the atomizer 100 can be provided with four cartridges 2, and the switching mechanism 4 can be rotated in the clockwise direction to realize the alternate switching of the first state and the second state. When the channel 5 of the switching mechanism 4 is only connected to the aerosol outlet 22 of the first cartridge and the mouthpiece 3, the switching mechanism 4 is in the first state; when the switching mechanism 4 is rotated again in the clockwise direction and switched from the first state to the second state, the aerosol outlets 22 of the first cartridge and the second cartridge are simultaneously connected to the mouthpiece 3; when the switching mechanism 4 is rotated again in the clockwise direction, the switching mechanism 4 can be switched from the second state to the first state, and only the aerosol outlet 22 of the second cartridge is connected to the mouthpiece 3; when the switching mechanism 4 is rotated again in the clockwise direction, it can be switched from the first state to the second state, and the aerosol outlets 22 of the second cartridge and the third cartridge are simultaneously connected to the mouthpiece 3. In this way, the switching mechanism 4 can continuously switch the first state and the second state alternately in the clockwise direction, so that the four cartridges 2 can realize the switching of eight different smoking flavors. It can be understood that rotating the switching mechanism 4 in the counterclockwise direction can also realize the alternate switching of the first state and the second state.

[0066] In some embodiments, referring to Figure 3 and Figure 5 , the end of the shell 1 close to the mouthpiece 3 can be provided with a plurality of air holes 11 corresponding to the plurality of aerosol outlets 22, wherein each air hole 11 can correspond to an aerosol outlet 22. In this embodiment, the aerosol outlet 22 on the cartridge 2 needs to be connected to the channel 5 on the switching mechanism 4 through the air hole 11 on the shell 1. The end of the aerosol outlet 22 close to the mouthpiece 3 can abut the outer periphery of the air hole 11 to realize the sealing between the aerosol outlet 22 and the air hole 11. For example, the outer periphery of the aerosol outlet 22 can be provided with a sealing ring, which can abut the outer periphery of the air hole 11 after the shell and the cartridge 2 are assembled, to realize the sealing between the aerosol outlet 22 and the air hole 11.

[0067] In other embodiments, the end of the shell 1 close to the mouthpiece 3 is provided with a large opening, and the aerosol outlets 22 of all cartridges 2 are connected to the channel 5 on the switching mechanism 4 through the opening. At this time, the shell 1 can not be provided with corresponding air holes 11 corresponding to the aerosol outlets 22 on each cartridge 2, but be directly connected to the channel 5 on the switching mechanism 4 through the aerosol outlet 22 on each cartridge 2.

[0068] In some embodiments, referring to Figure 6The conversion mechanism 4 can include a rotating member 41 and a sealing member 42. The rotating member 41 can be configured to rotate relative to the housing 1. The sealing member 42 can be configured to rotate with the rotating member 41. Thus, the sealing member 42 can seal the aerosol transmission path between the cartridge 2 and the mouthpiece 3, preventing the aerosol from leaking out of the conversion mechanism 4.

[0069] In some embodiments, the rotating member 41 can be provided with a first sub-channel 411, and the sealing member 42 can be provided with a second sub-channel 421. The first sub-channel 411 and the second sub-channel 421 can jointly form the channel 5 in the conversion mechanism 4.

[0070] In some embodiments, referring to Figure 7 and Figure 8 , the channel 5 in the conversion mechanism 4 can be formed in the rotating member 41. The sealing member 42 can be used to seal the fitting gap between the rotating member 41 and the housing 1.

[0071] In some embodiments, referring to Figure 9 and Figure 10 , the channel 5 in the conversion mechanism 4 can be formed in the sealing member 42. The sealing member 42 can be arranged between the rotating member 41 and the housing 1, and can rotate with the rotating member 41 relative to the housing 1.

[0072] In some embodiments, referring to Figure 7 , Figure 8 , Figure 9 and Figure 10 , the rotating member 41 and the sealing member 42 can both be arranged in a ring shape with the transmission channel 5 formed in the middle. The rotating member 41 can be provided with a ring-shaped wall 416 extending towards the mouthpiece 3 along the outer periphery of the transmission channel 5. The sealing member 42 can be provided with a ring-shaped column 424 extending towards the mouthpiece 3 along the outer periphery of the transmission channel 5. The ring-shaped column 424 can be arranged inside the ring-shaped wall 416, and can be in interference fit with the ring-shaped wall 416. To further ensure the fixation between the sealing member 42 and the rotating member 41, the ring-shaped column 424 can be provided with an extension structure 4241 at the end extending into the mouthpiece 3. The extension structure 4241 can have an outer diameter greater than the inner diameter of the ring-shaped wall 416, preventing the ring-shaped column 424 from being separated from the inside of the ring-shaped wall 416.

[0073] In order to make the connection between the seal 42 and the rotating member 41 more firm, one of the protrusions and the grooves can be arranged on the rotating member 41, and the other one of the protrusions and the grooves can be arranged on the seal 42 correspondingly. For example, a plurality of first protrusions 413 can be arranged on the inner side between the two ends of the rotating member 41 close to and away from the suction nozzle 3, and at the same time, the seal 42 can be provided with first grooves 422 corresponding to the first protrusions 413 between the two ends close to and away from the suction nozzle 3, at least a part of the first protrusions 413 is inserted into the first grooves 422, for example, the first protrusions 413 and the first grooves 422 can be in interference fit. Further, the second protrusions 414 can be arranged on the end of the rotating member 41 away from the suction nozzle 3, and the second grooves 423 can be arranged on the outer edge of the end of the seal 42 away from the suction nozzle 3 corresponding to the second protrusions 414, at least a part of the second protrusions 414 is inserted into the second grooves 423, for example, the second protrusions 414 and the second grooves 423 can be in interference fit.

[0074] In some embodiments, referring to Figure 11 and Figure 12 , the included angle between two adjacent channels 5 on the seal 42 is smaller than the included angle between two adjacent aerosol outlets 22. For example, the included angle between two adjacent channels 5 on the seal 42 can be a first included angle a, and the included angle between two adjacent aerosol outlets 22 on the cartridge 2 can be a third included angle c, the first included angle a is smaller than the third included angle c, so that the channel 5 on the conversion mechanism 4 can only guide the aerosol outlet 22 of one cartridge 2 to the suction nozzle 3, and the conversion mechanism 4 is in the first state. When the shell 1 has a plurality of air holes 11 corresponding to the plurality of aerosol outlets 22 close to the end of the suction nozzle 3, and each air hole 11 corresponds to one aerosol outlet 22, the included angle between two adjacent air holes 11 on the shell 1 can be a fourth included angle d, the fourth included angle d is equal to the third included angle c, and therefore the first included angle a is also smaller than the fourth included angle d.

[0075] In some embodiments, referring to Figure 11 , Figure 12 and Figure 13The channel 5 can include a first channel 51, a second channel 52 and a third channel 53 extending radially and communicating with each other, the second channel 52 being located between the first channel 51 and the third channel 53; a plurality of aerosol outlets 22 are circumferentially distributed and spaced apart from each other corresponding to the sealing members 42; and an included angle between the first channel 51 and the third channel 53 is equal to an included angle between two adjacent aerosol outlets 22. The included angle between the first channel 51 and the third channel 53 can be a second included angle b, and the included angle between the two aerosol outlets 22 on the adjacent cartridges 2 can be a third included angle c, the second included angle b being equal to the third included angle c. Thus, when the first channel 51 and the third channel 53 respectively communicate with the two adjacent aerosol outlets 22, the second channel 52 does not communicate with any aerosol outlet 22, the second channel 52 can be located between the two aerosol outlets 22 or be blocked by the shell 1, so as to communicate the two adjacent aerosol outlets 22 for the mouthpiece 3, and the conversion mechanism 4 is in the second state.

[0076] In some embodiments, referring to Figure 3 , Figure 4 and Figure 14 , the mouthpiece 3 and the conversion mechanism 4 can further include an elastic member 7, one end of the elastic member 7 being connected to the mouthpiece 3 and the other end of the elastic member 7 abutting against the conversion mechanism 4; a plurality of gears are arranged between the conversion mechanism 4 and the shell 1, the plurality of gears being distributed around the conversion mechanism 4; and the elastic member 7 is configured to keep the conversion mechanism 4 at a certain gear, and the arrangement of the elastic member 7 can keep the conversion mechanism 4 stably at a certain gear and provide a switching feeling for gear switching. For example, an opening is formed in an end of the mouthpiece 3 facing the shell 1, and the elastic member 7 includes a fixed end and a free end, wherein the fixed end of the elastic member 7 is fixed in the opening of the mouthpiece 3, and the free end of the elastic member 7 abuts against the conversion mechanism 4. The plurality of gears arranged between the conversion mechanism 4 and the shell 1 include: the gears are arranged on the conversion mechanism 4; or the gears are arranged on the shell 1; or a part of the gears are arranged on the conversion mechanism 4 and the other part of the gears are arranged on the shell 1.

[0077] In some embodiments, referring to Figure 3 , Figure 4 , Figure 11 and Figure 14The first concave cavity 8 can be provided on the side of the conversion mechanism 4 close to the suction nozzle 3. The bottom wall of the first concave cavity 8 can be provided with a plurality of stops, for example, the stops can be a plurality of recesses 412 arranged at intervals away from the suction nozzle 3. The elastic member 7 can be configured to abut against the bottom wall of the first concave cavity 8 when the conversion mechanism 4 rotates relative to the shell 1. In the process of rotation of the conversion mechanism 4, the elastic member 7 can slide from the bottom wall of the first concave cavity 8 into the recess 412, or can slide out of the recess 412. When the elastic member 7 slides from the bottom of the first concave cavity 8 into the recess 412, the elastic member 7 can fix the free end in the recess 412 by its own elastic force, and apply a biasing force to the recess 412, so that the conversion mechanism 4 stops rotating, thereby fixing the conversion mechanism 4 at a certain gear. When the elastic member 7 slides out of the recess 412 of the conversion mechanism 4 under the action of an external force, and slides again into another recess 412 through the bottom wall of the first concave cavity 8, the conversion mechanism 4 is switched from one gear to another. Through the cooperation of the elastic member 7 and the conversion mechanism 4, the conversion mechanism 4 can be fixed at different gears, thereby realizing the switching of different flavors of the cartridges 2 on the atomizer 100. For example, the shell 1 of the atomizer 100 can be provided with four cartridges 2, the sealing member 42 can be provided with three passages 5, and the first concave cavity 8 can be provided with eight recesses 412 corresponding to the eight gears of the conversion mechanism 4, each gear corresponding to a suction flavor of the atomizer 100. The recess 412 is arranged at the aerosol outlet of each cartridge 2 and between the aerosol outlets of two cartridges 2. The elastic member 7 can be a spring or an elastic ball structure, both of which can apply a biasing force to the conversion mechanism 4 to fix the conversion mechanism 4 at a certain recess 412 or position. At the same time, due to the elastic force of the elastic member 7, the conversion mechanism 4 can float up and down within a certain space, so that the conversion mechanism 4 can better realize the switching and fixing of gears.

[0078] Further, the bottom wall of the first concave cavity 8 can be provided with an anti-suction hole between the recesses 412. When the free end of the elastic member 7 rotates and slides into the anti-suction hole, the passage 5 on the conversion mechanism 4 can not be connected to the aerosol outlet 22 of any cartridge 2 or the suction nozzle 3, and the atomizer 100 is in a closed state and cannot be smoked. The anti-suction hole is located between the recesses 412 and on the rotation track of the free end of the elastic member 7 rotating around the bottom wall of the first concave cavity 8.

[0079] In some embodiments, referring to Figure 11 and Figure 14, the included angle between two adjacent two passages 5 on the sealing member 42 is equal to the included angle between two adjacent gears, i.e. the first included angle a is equal to the fifth included angle e. From the above embodiment, it can be known that the included angle between the first passage 51 and the third passage 53 can be equal to the included angle between two adjacent aerosol outlets 22, i.e. the second included angle b is equal to the third included angle c; and the fourth included angle d between two adjacent air holes 11 on the shell 1 is equal to the third included angle c. Therefore, when the conversion mechanism 4 rotates one gear relative to the shell 1, the passage 5 can rotate from one air hole 11 on the shell 1 to the middle position of two air holes 11, and when the conversion mechanism 4 rotates one gear relative to the shell 1 in the same direction again, the passage 5 can rotate from the middle position of two air holes 11 to the next air hole 11.

[0080] For example, four cartridges 2 can be arranged in the shell 1. The air passage 11 on the shell 1 corresponding to the aerosol outlet 22 of the first cartridge can be a first air passage, the air passage 11 on the shell 1 corresponding to the aerosol outlet 22 of the second cartridge can be a second air passage, and so on. The sealing member 42 can be provided with three channels 5 arranged in series and connected in communication. The original position of the first channel 51 on the sealing member 42 can correspond to the first air passage on the shell 1. At this time, the second channel 52 on the sealing member 42 is located between the first air passage and the second air passage, and the third channel 53 corresponds to the second air passage. At this time, the first air passage and the second air passage can be simultaneously communicated with the mouthpiece 3 through the first channel 51 and the second channel 52, that is, the aerosol outlets 22 of the first cartridge and the second cartridge are simultaneously communicated with the mouthpiece 3 through the first channel 51 and the second channel 52. At this time, the conversion mechanism 4 is in the second state. When the sealing member 42 rotates one position with the rotating member 41, the first channel 51 is transferred to between the first air passage and the second air passage, the second channel 52 is transferred to communicate with the second air passage, and the third channel 53 is transferred to between the second air passage and the third air passage. At this time, the second air passage can be communicated with the mouthpiece 3 through the second channel 52, that is, the aerosol outlet 22 of the second cartridge is communicated with the mouthpiece 3 through the second channel 52. At this time, the conversion mechanism 4 is in the first state, and the conversion mechanism 4 completes the conversion from the second state to the first state. When the sealing member 42 rotates one position again in the same direction with the rotating member 41, the first channel 51 is transferred to communicate with the second air passage, the second channel 52 is transferred to between the second air passage and the third air passage, and the third channel 53 is transferred to communicate with the third air passage. At this time, the aerosol outlets 22 of the second cartridge and the third cartridge are simultaneously communicated with the mouthpiece 3 through the first channel 51 and the second channel 52, that is, the conversion mechanism 4 is in the second state, and the conversion mechanism 4 completes the conversion from the first state to the second state. In this way, the conversion mechanism 4 can rotate one circle by rotating eight times, and the sealing member 42 can complete one rotation by rotating eight times, so that the eight positions of the conversion mechanism 4 can be changed, the second state and the first state can be changed eight times, and the four cartridges 2 can be changed in eight flavors.

[0081] In some embodiments, referring to Figure 15 、 Figure 16 、 Figure 17 and Figure 18 , the shell 1 can be provided with a second cavity 9 near the end close to the mouthpiece 3, and the inner wall around the second cavity 9 can be provided with a relief structure 13. The relief structure 13 includes a plurality of upper convex portions 131 and a plurality of lower concave portions 132. The conversion mechanism 4 can be provided with a plurality of matching portions 415 corresponding to the plurality of lower concave portions 132. The plurality of matching portions 415 are configured to rotate along the relief structure 13 under external actuation and match with different lower concave portions 132 under the abutment of the elastic member 7.

[0082] Exemplarily, the inside of the shell 1 of the atomizer 100 can be provided with four cartridges 2, the sealing member 42 can be provided with three passages 5, and the inner wall of the second recess 9 can be provided with eight undulating structures 13, i.e., the number of the upper convex portions 131 and the lower concave portions 132 can also be eight, i.e., the conversion mechanism 4 is provided with eight adjustable gears, and each gear can correspond to one smoking taste of the atomizer 100. The aerosol outlet of each cartridge 2 and the middle of the aerosol outlets of the two cartridges 2 are both provided with the lower concave portions 132. The cooperation portion 415 can be provided on the end of the rotating member 41 close to the shell 1 and correspond to the lower concave portions 132. When the conversion mechanism 4 is in the first state or the second state or in a certain cooperation gear, at least a part of the cooperation portion 415 is located in the lower concave portion 132. When the rotating member 41 rotates under the action of an external force, the end of the cooperation portion 415 away from the mouthpiece 3 can rotate on the undulating structure 13. When the cooperation portion 415 slides from the upper convex portion 131 into the lower concave portion 132, the conversion mechanism 4 can remain in the corresponding gear under the biasing force of the elastic member 7. When it is needed to adjust the conversion mechanism 4 to other gears, the user needs to slightly increase the rotating force, which needs to be large enough to overcome the biasing force of the elastic member 7 on the rotating member 41, so that the cooperation portion 415 can be turned out of the lower concave portion 132, and the cooperation portion 415 can be turned into the next lower concave portion 132 via the connected upper convex portion 131, and the conversion mechanism 4 completes the adjustment from one gear to another. Exemplarily, the elastic member 7 can be a spring or an elastic ball structure, both of which can exert a biasing force on the conversion mechanism 4 to fix the conversion mechanism 4 at a certain concave portion 412 or position. At the same time, due to the elastic force of the elastic member 7, the conversion mechanism 4 can float up and down within a certain space, so that the conversion mechanism 4 can better realize the switching and fixing of gears.

[0083] In some embodiments, the number of the cooperation portions 415 can be one or more. In some embodiments, in order to facilitate the rotation of the rotating member 41 relative to the shell 1, the number of the cooperation portions 415 can be two, and the two cooperation portions 415 are oppositely arranged. Further, in order to make the rotating member 41 rotate more smoothly relative to the shell 1, the number of the cooperation portions 415 can be three, and the three cooperation portions 415 are equidistantly arranged, so that the rotating member 41 rotates more stably and does not deviate.

[0084] In some embodiments, please refer to Figure 19The electronic atomization device 1000 can include the atomizer 100 in the above-described embodiments and the power supply 200 electrically connected with the atomizer 100 to provide the atomizer 100 with electric energy. The electronic atomization device 1000 can further be provided with a plurality of airflow sensors electrically connected with the power supply 200. Each cartridge 2, i.e., each aerosol channel 21, is respectively provided with an airflow sensor. In the switching process, only the cartridge 2 in communication with the mouthpiece 3 can be triggered to start when a suction action is generated, and the other cartridges 2 not in communication cannot start when a suction action is generated. For example, in the present embodiment, only one or two cartridges 2 in communication with the mouthpiece 3 can be triggered to start when a suction action is generated. Further, the heating assembly in the cartridge 2 can heat the tobacco tar in the cartridge 2 to generate aerosol for the user to smoke.
