[0002] Electronic cigarettes are aerosol-generating devices that heat tobacco oil to form smoke for users to inhale.

[0003] The Chinese utility model patent with the announcement number CN216931893U disclosed a multi-smoke cartridge atomizer on July 12, 2022. The multi-smoke cartridge atomizer includes an oil cup for accommodating smoke oil, an atomization component connected to the oil cup and used to heat the smoke oil to form smoke, and a suction nozzle component for providing a suction part, wherein the suction nozzle component includes a fixed frame and a suction nozzle rotatably mounted on the fixed frame, and the fixed frame is provided with a plurality of through holes, each of which is correspondingly connected to an output end of an atomization component, and the bottom of the suction nozzle is provided with a first flue port and at least one second flue port that can be opened and closed. The suction nozzle rotates relative to the fixed frame so that when the first flue port is connected to the through hole, the second flue port is opened, so that the smoke can pass through the through hole, the first flue port and the second flue port in sequence for the user to inhale.

[0004] However, after the first flue opening is connected to the through hole, the nozzle is easily rotated. Therefore, it cannot be guaranteed that the first flue opening and the through hole are completely aligned, which may cause insufficient smoke to flow out of the nozzle or the generated smoke to remain in the atomizer assembly. In the above case, the inside of the atomizer assembly may be easily damaged by the smoke. Utility Model Content

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] Please also read Figures 1 to 3 , Figure 1 It is a structural schematic diagram of an aerosol generating device 100 provided in one embodiment of the utility model; Figure 2 yes Figure 1 A schematic cross-sectional structure diagram of the aerosol generating device 100; Figure 3 yes Figure 1 Exploded view of the aerosol generating device 100.

[0035] The aerosol generating device 100 provided in one embodiment of the utility model comprises an atomizing mainframe 10, a main support 20, a nozzle 30 and a magnetic suction component 40; the atomizing mainframe 10 comprises two atomizing components 11, each of which is provided with an atomizing cavity 111; the main support 20 is provided with two air guide holes 21, each atomizing component 11 is mounted on the main support 20 and is located on one side of a corresponding air guide hole 21, and the atomizing cavity 111 of each atomizing component 11 is connected to the corresponding air guide hole 21. 1 is connected; the suction nozzle 30 is rotatably mounted on the main bracket 20, and an air outlet channel 31 is opened on the suction nozzle 30, and both ends of the air outlet channel 31 pass through the suction nozzle 30; the magnetic suction component 40 includes a first magnetic suction member 41 and a second magnetic suction member 42, the two first magnetic suction members 41 are connected to the main bracket 20, and one second magnetic suction member 42 is connected to the suction nozzle 30, and when the suction nozzle 30 is rotated so that the second magnetic suction member 42 is attracted to one of the first magnetic suction members 41, the air outlet channel 31 is aligned with and connected to a corresponding air guide hole 21.

[0036] Here, it should be noted that the atomizer assembly 11 is used to store e-liquid, and the atomizer assembly 11 can heat the e-liquid to form smoke for the user to inhale. In this embodiment, the two atomizer assemblies 11 can store e-liquids of different flavors for the user to choose smoke of different flavors; the two atomizer assemblies 11 can also store the same e-liquid to increase the oil capacity of a single aerosol generating device 100. Furthermore, the aerosol generating device 100 can change the number of atomizer assemblies 11 according to actual needs, such as setting three atomizer assemblies 11 or four atomizer assemblies 11, etc. In this embodiment, the number of atomizer assemblies 11 is set to two for example.

[0037] When the user chooses a flavor to inhale, the user can rotate the suction nozzle 30 so that the air outlet channel 31 on the suction nozzle 30 is aligned with one of the air guide holes 21, and the atomization component 11 located on one side of the air guide hole 21 can form smoke, and the smoke passes through the air guide hole 21 and the air outlet channel 31 in turn for the user to inhale. The first magnetic suction member 41 is set to two, and the two first magnetic suction members 41 are respectively located on one side of the corresponding two air guide holes 21, and the second magnetic suction member 42 is set to one, and the second magnetic suction member 42 is located on one side of the air outlet channel 31. After the suction nozzle 30 is rotated, when the air outlet channel 31 is aligned with and connected to an air guide hole 21, the second magnetic suction member 42 and the corresponding first magnetic suction member 41 will be attracted to each other, so that the connection between the suction nozzle 30 and the main bracket 20 is more stable. In the case of no interference from external forces, the suction nozzle 30 is difficult to continue to rotate, thereby ensuring that the smoke passes through the air guide hole 21 and the air outlet channel 31 smoothly.

[0038] Optionally, the caliber of the air outlet channel 31 is consistent with the caliber of the air guide hole 21 .

[0039] Optionally, the first magnetic member 41 and the second magnetic member 42 may both be magnets; or, one of the first magnetic member 41 and the second magnetic member 42 may be a magnet, and the other may be a metal material such as nickel, iron, cobalt, etc. that can be attracted by a magnet.

[0040] If the air outlet channel 31 is not aligned with the air guide hole 21, part of the air guide hole 21 will be blocked by the side wall of the air outlet channel 31. When the smoke flows from the air guide hole 21 to the air outlet channel 31, the smoke will adhere to the blocked part and form condensate. The condensate will flow back into the atomizer assembly 11 and easily corrode the atomizer assembly 11. In addition, the amount of smoke inhaled by the user will be reduced, and the user experience will be poor.

[0041] In addition, the internal structure of the atomizer assembly 11 is illustrated herein, and the atomizer assembly 11 includes an oil cup 112, an end cover 113, an air guide pipe 114, oil guide cotton 115 and a heating wire 116. The end cover 113 is sealed to the side of the oil cup 112 facing the base 25 by sealing silicone, the air guide pipe 114 is installed in the oil cup 112, the atomization chamber 111 is opened in the air guide pipe 114, and an oil storage bin 1121 and an oil outlet 1122 are opened in the oil cup 112. The oil outlet 1122 is connected to the oil storage bin 1121 and the air guide pipe 114, and the oil guide cotton 115 is sleeved on the outside of the heating wire 116 and accommodated in the atomization chamber 111 together.

[0042] See also Figure 3 and Figure 4 , Figure 4 yes Figure 1 Another exploded view of the aerosol generating device 100.

[0043] In one embodiment, the suction nozzle 30 includes a cover body 32 and a shielding portion 33. The cover body 32 is rotatably mounted on the main bracket 20, and the shielding portion 33 is connected to the cover body 32. When the cover body 32 is rotated so that the air outlet channel 31 is aligned and connected to a corresponding air guide hole 21, the shielding portion 33 closes the other air guide hole 21.

[0044] Specifically, the cover body 32 and the shielding part 33 are integrally manufactured, and the shielding part 33 is located on the side of the cover body 32 facing the main bracket 20, and the shielding part 33 is extended in the direction toward the main bracket 20. The user rotates the cover body 32 so that the air outlet channel 31 is aligned with and connected to one air guide hole 21, and the corresponding first magnetic attraction member 41 and the second magnetic attraction member 42 are attracted to each other. At the same time, the shielding part 33 closes the other air guide hole 21, so that the user can only select one atomization assembly 11 for inhalation. In other words, the user can only inhale smoke of one flavor.

[0045] If the shielding portion 33 is not provided, and there is a gap between the suction nozzle 30 and the main bracket 20, that is, the other air guide hole 21 is connected to the outside, then when the air pressure changes, the corresponding other atomization component 11 will generate smoke by heating the e-liquid, and the smoke is difficult to be discharged through the suction nozzle 30, which may easily cause waste of the e-liquid.

[0046] In one embodiment, the magnetic component 40 also includes a third magnetic component 43, which is connected to the shielding portion 33. When the second magnetic component 42 is attracted to one of the first magnetic components 41, the third magnetic component 43 is attracted to the other first magnetic component 41, and the shielding portion 33 closes the corresponding air guide hole 21.

[0047] Specifically, the user rotates the nozzle 30, and the air outlet channel 31 is aligned with one air guide hole 21, and the corresponding first magnetic component 41 is attracted to the second magnetic component 42. At the same time, the other first magnetic component 41 is attracted to the third magnetic component 43, thereby ensuring that the shielding portion 33 closes the other air guide hole 21 to ensure that the user only inhales one flavor of e-liquid.

[0048] In one embodiment, the main bracket 20 includes a first positioning portion 22, which extends in the direction of the suction nozzle 30. Two first positioning portions 22 are provided, and two air guide holes 21 respectively pass through the two first positioning portions 22. The suction nozzle 30 also includes a second positioning portion 34, which extends in the direction of the main bracket 20. The air outlet channel 31 passes through the second positioning portion 34. The two first magnetic components 41 are respectively connected to the two first positioning portions 22, and the second magnetic component 42 is connected to the second positioning portion 34. When an air guide hole 21 is connected to the air outlet channel 31, the second positioning portion 34 abuts against a corresponding first positioning portion 22, the second magnetic component 42 is attracted to a corresponding first magnetic component 41, the other first positioning portion 22 abuts against the shielding portion 33, and the other first magnetic component 41 is attracted to the third magnetic component 43.

[0049] Specifically, the air guide hole 21 passes through the first positioning portion 22, the output end of the atomizer assembly 11 is connected to the air guide hole 21, and the air outlet channel 31 passes through the second positioning portion 34. When one air guide hole 21 is connected to the air outlet channel 31, the second positioning portion 34 abuts against a corresponding first positioning portion 22 to ensure the air tightness when the air guide hole 21 is connected to the air outlet channel 31. If the first positioning portion 22 and the second positioning portion 34 do not abut against each other, there is still a gap between the air guide hole 21 and the air outlet channel 31, and the smoke generated by the atomizer assembly 11 can overflow through the gap, thereby causing the amount of smoke inhaled by the user through the nozzle 30 to decrease, resulting in a poor user experience. In addition, the other first positioning portion 22 abuts against the shielding portion 33, thereby preventing a gap from being left between the first positioning portion 22 and the shielding portion 33 to ensure air tightness.

[0050] In one embodiment, the first positioning portion 22, the second positioning portion 34 and the shielding portion 33 are all cylindrical structures, the first magnetic member 41, the second magnetic member 42 and the third magnetic member 43 are all annular structures, each first magnetic member 41 is sleeved on a corresponding first positioning portion 22, the second magnetic member 42 is sleeved on the second positioning portion 34, and the third magnetic member 43 is sleeved on the shielding portion 33; when the second positioning portion 34 abuts against a corresponding first positioning portion 22, the end face of the first magnetic member 41 abuts against the end face of the second magnetic member 42, and the second positioning portion 34 abuts against the end face of the second magnetic member 42, and the second positioning portion 34 abuts against the end face of the second magnetic member 42. The central axis of the part 34, the central axis of the corresponding first positioning part 22, the central axis of the second magnetic member 42, and the central axis of the corresponding first magnetic member 41 are located on the same straight line, the other first positioning part 22 is abutted against the shielding part 33, the end face of the corresponding other first magnetic member 41 is abutted against the end face of the second magnetic member 42, and the central axis of the other first positioning part 22, the central axis of the shielding part 33, the central axis of the other first magnetic member 41 and the central axis of the third magnetic member 43 are all located on another straight line.

[0051] Specifically, when a first magnetic member 41 and a second magnetic member 42 are attracted to each other, the end face of the first magnetic member 41 abuts against the end face of the second magnetic member 42, and at the same time, the second positioning portion 34 abuts against the corresponding first positioning portion 22; the first magnetic member 41 is sleeved on the first positioning portion 22, and the second magnetic member 42 is sleeved on the second positioning portion 34. The first magnetic member 41 and the second magnetic member 42 are attracted to each other to form a sealing protection for the first positioning portion 22 and the second positioning portion 34. It can be understood that when the first magnetic member 41 and the second magnetic member 42 are attracted to each other, a chamber can be formed, and the first positioning portion 22 and the second positioning portion 34 are located in the chamber to ensure that smoke does not leak out.

[0052] Moreover, the end face of the first magnetic member 41 and the end face of the second magnetic member 42 are against each other, the first positioning portion 22 and the second positioning portion 34 are against each other, and the second positioning portion 34 can rotate with the rotation of the nozzle 30, so the end face of the first positioning portion 22, the end face of the second positioning portion 34, the end face of the first magnetic member 41 and the end face of the second magnetic member 42 are located on the same plane. The central axis of the first positioning portion 22, the central axis of the second positioning portion 34, the central axis of the first magnetic member 41 and the central axis of the second magnetic member 42 are located on the same straight line. In the actual production process, the above structure can make the internal structure of the aerosol generating device 100 more compact and the parts more standardized.

[0053] Similarly, the central axis of another first positioning portion 22, the central axis of another magnetic member, the central axis of the shielding portion 33 and the central axis of the third magnetic member 43 are all located on another straight line, which also has a similar effect and is not elaborated here.

[0054] See also Figure 2 , Figure 3 and Figure 5 , Figure 5 yes Figure 1 Exploded view of the main support of the aerosol generating device.

[0055] In one embodiment, the main bracket 20 includes a top plate 23, the circumferential outer edge of the top plate 23 is fitted and abutted against the circumferential outer edge of the cover body 32 to enclose and form a sealed cavity 50, the first positioning portion 22, the second positioning portion 34 and the shielding portion 33 are all accommodated in the sealed cavity 50, the end face of one first positioning portion 22 facing the suction nozzle 30 is adapted to and abutted against the end face of the second positioning portion 34 facing the main bracket 20, and the end face of the other first positioning portion 22 facing the suction nozzle 30 is adapted to and abutted against the end face of the shielding portion 33 facing the main bracket 20.

[0056] Specifically, the circumferential outer edge of the top plate 23 is fitted against the circumferential outer edge of the cover body 32 to form a sealed cavity 50 to ensure that the gas does not leak. Moreover, the appearance of the aerosol generating device 100 is more compact. The end face of the first positioning portion 22 is adapted to the end face of the second positioning portion 34, so that when the first positioning portion 22 is abutted against the second positioning portion 34, the gap between the first positioning portion 22 and the second positioning portion 34 is smaller, thereby improving the air tightness of the aerosol generating device 100. Similarly, the end face of the first positioning portion 22 is adapted to the end face of the shielding portion 33, which also has the effect of improving the air tightness of the aerosol generating device 100, which will not be elaborated here.

[0057] In one embodiment, a battery compartment 24 is provided inside the main bracket 20, and a battery 60 is installed in the battery compartment 24. The main bracket 20 includes a base 25, and the base 25 includes two electrode connectors 251. The two electrode connectors 251 are electrically connected to the battery 60. The base 25 has two receiving cavities 252, and each electrode connector 251 extends into a corresponding receiving cavity 252; a wiring terminal 117 is provided at the bottom of each atomizer assembly 11, and each atomizer assembly 11 is installed in a corresponding receiving cavity 252, and the wiring terminal 117 of each atomizer assembly 11 cooperates with a corresponding electrode connector 251.

[0058] Specifically, the two electrode connectors 251 are electrically connected to a battery 60, so that the structure inside the main bracket 20 is more compact. The atomizer assembly 11 is installed in the receiving cavity 252, and the wiring terminal 117 on the bottom of the atomizer assembly 11 can cooperate with the electrode connector 251, so that the atomizer assembly 11 and the battery 60 are electrically connected, and the atomizer assembly 11 can heat the e-liquid. One end of the electrode connector 251 extends into the receiving cavity 252, so that the user can observe the position of the electrode connector 251 when installing the atomizer assembly 11, and align the wiring terminal 117 with the electrode connector 251 to install the atomizer assembly 11.

[0059] In some other embodiments, the number of the receiving chambers 252 can be designed according to the number of the atomizer assemblies 11 , and the multiple atomizer assemblies 11 can be electrically connected to the same battery 60 , so that the interior of the main bracket 20 is more compact.

[0060] In one embodiment, the main bracket 20 also includes a main body 26, and the top plate 23 and the base 25 are respectively connected to the opposite ends of the main body 26, and the circumferential outer walls of the top plate 23, the base 25 and the main body 26 enclose a receiving cavity 252, and the cavity opening of the receiving cavity 252 is far away from the main body 26.

[0061] Specifically, the opening of the accommodating cavity 252 is away from the main body 26, so that the top plate 23, the base 25 and the main body 26 are roughly I-shaped. The purpose of this arrangement is that when the user installs or replaces the atomizer assembly 11, the atomizer assembly 11 can be installed in the main bracket 20 by inserting it into the main bracket 20 from the side of the main bracket 20, so as to facilitate the user to replace it.

[0068] Specifically, when the user inhales, the air pressure in the air inlet cavity 81 will change. The sensing microphone 92 is installed on the microphone bracket 91 and is located in the air inlet cavity 81. The air pressure in the air inlet cavity 81 and the connecting hole 27 will change.
