[0033] Please also read Figure 1 , Figure 2 , Figure 3 and Figure 4 , 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 diagram of a partial explosion structure of the aerosol generating device 100; Figure 3 yes Figure 1 A schematic cross-sectional structure diagram of the atomizing assembly 20 of the aerosol generating device 100; Figure 4 yes Figure 1 Schematic diagram of the explosion structure of the aerosol generating device 100.

[0034] An aerosol generating device 100 provided in an embodiment of the utility model includes a main support 10, an atomizing assembly 20, a nozzle 30 and an adsorption assembly 40. The main support 10 includes a body 11 and a base 12. The base 12 is connected to one end of the body 11. An installation cavity 111 is formed between the base 12 and the body 11. The two installation cavities 111 are respectively located on opposite sides of the body 11. The base 12 includes a positioning surface 121, which faces the installation cavity 111. A guide strip 122 is convexly provided on the positioning surface 121. The guide strip 122 is extended from one installation cavity 111 to another installation cavity 111.

[0035] Each atomizer assembly 20 is accommodated in a corresponding installation cavity 111, each atomizer assembly 20 is installed on the base 12, the bottom surface of each atomizer assembly 20 is against the positioning surface 121, and a guide groove 21 is provided on the bottom of each atomizer assembly 20, and the guide groove 21 is extended from one installation cavity 111 to another installation cavity 111, and one end of the guide groove 21 passes through the side of the atomizer assembly 20 facing the main body 11, and the guide strip 122 is accommodated in the guide groove 21, and the guide strip 122 is against the groove wall of the guide groove 21, and each atomizer assembly 20 is provided with an atomizer cavity 22;

[0036] The suction nozzle 30 is mounted on the main support 10, and a suction channel 31 is provided in the suction nozzle 30. The suction nozzle 30 can rotate relative to the main support 10, so that the suction channel 31 can selectively communicate with the atomization chamber 22 of one of the atomization assemblies 20;

[0037] The adsorption component 40 includes a first magnetic component 41 and a second magnetic component 42. The first magnetic component 41 is installed on the side of the atomization component 20 facing the main body 11, and the second magnetic component 42 is installed on the side of the main body 11 facing the atomization component 20. The first magnetic component 41 and the second magnetic component 42 are adsorbed to each other.

[0038] Specifically, the main body 11 and the base 12 are integrally manufactured, the base 12 is located at the end of the main body 11, the main body 11 is roughly strip-shaped, the main body 11 and the base 12 form two mounting cavities 111, the two mounting cavities 111 are respectively located on opposite sides of the main body 11, and the two atomizer assemblies 20 can be respectively accommodated in the two mounting cavities 111. When the atomizer assembly 20 is fully pushed into the mounting cavity 111, the first magnetic member 41 and the second magnetic member 42 are adsorbed to ensure that the atomizer assembly 20 is difficult to fall off from the mounting cavity 111. Moreover, the two atomizer assemblies 20 can be placed in the mounting cavity 111 facing each other, so that the user can replace the atomizer assembly 20. Among them, the first magnetic member 41 and the second magnetic member 42 are both magnets. In some other embodiments, one of the first magnetic member 41 and the second magnetic member 42 is a magnet, and the other is a metal material that can be attracted by a magnet, such as nickel, iron, cobalt, etc. In addition, it should be noted that the atomizer assembly 20 can be understood as a component equipped with smoke oil and can heat the smoke oil.

[0039] The bottom of the atomizer assembly 20 has a guide groove 21, and a guide strip 122 is convexly provided on the positioning surface 121 of the base 12. The guide strip 122 extends from one mounting cavity 111 to another mounting cavity 111. During the process of installing the atomizer assembly 20 in the mounting cavity 111, the atomizer assembly 20 needs to be pushed into the mounting cavity 111 along the guide strip 122. The purpose of this arrangement is that the user can push two atomizer assemblies 20 into two mounting cavities 111 in the same plane. In this embodiment, the two atomizer assemblies 20 can be pushed into the two mounting cavities 111 in the same horizontal plane, so as to facilitate the user to install or replace the atomizer assembly 20. Moreover, the setting of the guide strip 122 can improve the stability of the atomizer assembly 20 during the installation process.

[0040] After the atomizer assembly 20 is installed in the installation cavity 111 , the bottom surface of the atomizer assembly 20 abuts against the positioning surface 121 , thereby ensuring the stability of the connection between the atomizer assembly 20 and the base 12 and preventing a gap from appearing between the atomizer assembly 20 and the base 12 so that the atomizer assembly 20 is placed unstably.

[0041] In this embodiment, the suction nozzle 30 is rotatably mounted on the main bracket 10, so that the suction nozzle 30 can rotate relative to the main body 11, so that the suction channel 31 in the suction nozzle 30 is connected to the atomization chamber 22 of one of the atomization assemblies 20. The purpose of this arrangement is that the two atomization assemblies 20 can be equipped with e-liquids of different flavors, and the suction nozzle 30 can be rotated so that the user can experience smoke of different flavors.

[0042] In one embodiment, the guide strip 122 includes a connecting portion 1221 and a guiding portion 1222, one end of the connecting portion 1221 abuts against the main body 11, and the other end of the connecting portion 1221 is connected to the guiding portion 1222, and the height of the guiding portion 1222 protruding from the positioning surface 121 gradually decreases along the direction from the main body 11 to the connecting portion 1221, and the atomizer assembly 20 abuts against the main body 11 on the side facing the main body 11.

[0043] Specifically, the connecting portion 1221 and the guiding portion 1222 are integrally manufactured, the connecting portion 1221 is roughly in the shape of a long strip, and the guiding portion 1222 is roughly in the shape of a triangle. The purpose of such a configuration is that when the atomizer assembly 20 is installed in the installation cavity 111, the guiding portion 1222 has a guiding function to prevent the guiding strip 122 from being separated from the guiding groove 21, resulting in unstable installation of the atomizer assembly 20.

[0044] One end of the connecting portion 1221 abuts against the side of the main body 11. The purpose of this arrangement is that when the atomizer assembly 20 is fully installed in the mounting cavity 111, the side of the atomizer assembly 20 facing the main body 11 can abut against the main body 11. The side of the main body 11 can limit and position the atomizer assembly 20 and facilitate the user to determine whether the atomizer assembly 20 is fully installed in the mounting cavity 111.

[0045] If one end of the connecting portion 1221 does not abut against the main body 11 , the user may not continue to push the guide bar 122 into the guide groove 21 until it is completely in contact with the main body 11 , and a gap may exist between the atomizing assembly 20 and the main body 11 , causing the atomizing assembly 20 to fall off easily.

[0046] In this embodiment, the center of gravity of the atomizer assembly 20 may be located at one side of the atomizer assembly 20 facing the main body 11 , so that the atomizer assembly 20 is not easily tilted in a direction away from another atomizer assembly 20 .

[0047] See also Figure 3 , Figure 4 and Figure 5 , Figure 5 yes Figure 1 Schematic diagram of the cross-sectional structure of the aerosol generating device 100.

[0048] In one embodiment, a battery compartment 112 is provided in the main body 11, and a battery 50 is installed in the battery compartment 112. The base 12 includes an electrode connector 123, and the electrode connector 123 is electrically connected to the battery 50. The electrode connector 123 extends into the installation cavity 111, and the electrode connector 123 is located at the end of the guide portion 1222 away from the connecting portion 1221; a wiring hole 23 is recessed at the bottom of the atomizer assembly 20, and a wiring terminal 60 is provided in the wiring hole 23. The wiring hole 23 is located on one side of the guide groove 21, and the electrode connector 123 is inserted into the wiring hole 23 and abuts against the wiring terminal 60.

[0049] Specifically, when the electrode connector 123 is in contact with the wiring terminal 60, the atomizer assembly 20 is electrically connected to the battery 50, and the battery 50 provides electrical energy to the atomizer assembly 20, so that the atomizer assembly 20 can heat the tobacco oil to form smoke. The electrode connector 123 is located at the end of the guide portion 1222 away from the connecting portion 1221. The purpose of this arrangement is that when the atomizer assembly 20 is pushed into the installation cavity 111, the electrode connector 123 is first accommodated in the guide groove 21. As the atomizer assembly 20 is pushed in, the electrode connector 123 moves relative to the atomizer assembly 20 toward the wiring hole 23 until the atomizer assembly 20 is in contact with the body 11, and the electrode connector 123 is also inserted into the wiring hole 23 and contacts the wiring terminal 60; through the above operation, the user does not need to align the electrode connector 123 with the wiring hole 23 before installing the atomizer assembly 20, thereby achieving the effect of facilitating the user to install the atomizer assembly 20.

[0050] In some other embodiments, the electrode connector 123 may be an electrode sheet, wherein one end of the electrode sheet is exposed in the mounting cavity 111 , and the other end of the electrode sheet is electrically connected to the battery 50 .

[0051] See also Figure 5 and Figure 6 , Figure 6 yes Figure 1 A schematic structural diagram of the main support 10 and the bottom cover 70 of the aerosol generating device 100.

[0052] In one embodiment, the aerosol generating device 100 further includes a bottom cover 70, which is detachably connected to the base 12, and the bottom cover 70 and the base 12 enclose an air inlet cavity 71, and the bottom cover 70 includes an air inlet portion 72, and the air inlet portion 72 is provided with an air inlet hole 721, and the air inlet hole 721 is penetrated in the air inlet portion 72, and the air inlet hole 721 communicates with the air inlet cavity 71 and the outside; the base 12 is also provided with a connecting hole 124, and the connecting hole 124 communicates with the air inlet cavity 71 and the atomizing cavity 22;

[0053] The aerosol generating device 100 further includes a sensing component 80 . The sensing component 80 includes a sensing bracket 81 and a sensing microphone 82 . The sensing bracket 81 is sleeved on the air inlet portion 72 , and the sensing microphone 82 is mounted on the sensing bracket 81 .

[0054] Specifically, the sensing bracket 81 is located in the air inlet cavity 71, and the sensing microphone 82 is also located in the air inlet cavity 71. The user inhales through the suction nozzle 30, and the gas enters the air inlet cavity 71 from the outside, and the gas in the air inlet cavity 71 enters the atomizing cavity 22 through the connecting hole 124. Since the sensing microphone 82 is installed on the sensing bracket 81, and the sensing bracket 81 is sleeved on the air inlet portion 72, the sensing microphone 82 can sense the change of air pressure and feedback the corresponding signal during the process of the gas entering the atomizing cavity 22 through the connecting hole 124. There is no need to set an additional airway for the sensing microphone 82 in the atomizing assembly 20 to connect to the suction nozzle 30. The sensing microphone 82 can also sense the change of air pressure, thereby avoiding the need to set an additional sensing airway. Such a setting makes the internal structure of the aerosol generating device 100 more compact.

[0055] When the sensing microphone 82 is damaged, the sensing microphone 82 can be taken out by removing the bottom cover 70 .

[0056] In one embodiment, two guide bars 122 are provided, the communication hole 124 is located between the two guide bars 122 , and the two guide bars 122 are symmetrically arranged relative to the communication hole 124 .

[0057] Specifically, when the user inhales, the gas flows from the outside along the path of the air inlet 721, the air inlet cavity 71, the connecting hole 124, the atomizing cavity 22 and the suction channel 31. The guide strips 122 are set to two, and the corresponding guide grooves 21 are also set to two. Moreover, the two guide strips 122 are symmetrically arranged relative to the connecting hole 124, and the corresponding two guide grooves 21 are also symmetrically arranged relative to the connecting hole 124, and the connecting hole 124 is connected to the atomizing cavity 22. The purpose of this arrangement is that when the atomizing assembly 20 is pushed into the installation cavity 111, the atomizing assembly 20 can be pushed into the installation cavity 111 more smoothly relative to both sides of the connecting hole 124, so as to prevent the bottom of the atomizing assembly 20 from having a gap with the positioning surface 121. For example: when the guide strip 122 is set to one, when the atomizing assembly 20 is pushed into the atomizing assembly 20, the atomizing assembly 20 is tilted toward one side of the guide strip 122 relative to the connecting hole 124, resulting in a gap between the bottom of the atomizing 20 and the positioning surface 121, insufficient air intake, and poor suction effect.

[0058] In this embodiment, the atomizing chamber 22 is substantially a cylindrical cavity, and the atomizing assembly 20 is symmetrically arranged relative to the central axis of the atomizing chamber 22 .

[0059] In one embodiment, the aerosol generating device 100 also includes a circuit board 90, which is installed in the air inlet cavity 71. Two air inlet parts 72 are provided, and two air inlet holes 721 are provided. The two air inlet holes 721 correspond to the atomization cavities 22 connected to the two atomization components 20 respectively. Two sensing components 80 are provided, and the two sensing microphones 82 are electrically connected to the circuit board 90. The battery 50 is electrically connected to the circuit board 90.

[0060] Specifically, the battery 50 is located in the main body 11, the circuit board 90 is located on the side of the battery 50 facing the base 12, and the circuit board 90 is electrically connected to the battery 50; the two induction microphones 82 are both located in the air inlet cavity 71, and the two induction microphones 82 are electrically connected to the circuit board 90. The purpose of this arrangement is that only one circuit board 90 is required to control the functions of charging the battery 50, controlling the atomization assembly 20 to heat the e-liquid, and receiving the signal of the induction microphone 82, so that the internal structure of the aerosol generating device 100 is more compact.

[0061] Here, it should be noted that the circuit board 90 can be a PCB board.

[0062] In one embodiment, a vertical projection of the communication hole 124 on the bottom cover 70 is separated from a vertical projection of the sensing microphone 82 on the bottom cover 70 .

[0063] Specifically, the smoke formed by the heated smoke oil in the atomizer assembly 20 will form condensate during the movement along the atomizer chamber 22 to the suction channel 31, and the condensate will drip in the opposite direction, that is, the condensate will drip along the suction channel 31, the atomizer chamber 22, the connecting hole 124 and the air inlet 721. Because the vertical projection of the induction microphone 82 on the bottom cover 70 is separated from the vertical projection of the connecting hole 124 on the bottom cover 70, the condensate is not easy to drip on the induction microphone 82. Therefore, the induction microphone 82 can be protected from being contaminated by the condensate.

[0065] In one embodiment, the main bracket 10 also includes a top plate 13, and the top plate 13 and the base 12 are respectively connected to the opposite ends of the main body 11, and the top plate 13, the main body 11 and the base 12 together enclose two installation cavities 111. The top plate 13 is provided with a strip-shaped positioning block 131 protruding from one side of the installation cavity 111, and the positioning block 131 extends into the installation cavity 111. A strip-shaped positioning groove 24 is opened on the top of the atomizer assembly 20, and one end of the positioning groove 24 passes through the side of the atomizer assembly 20 facing the main body 11. The positioning block 131 and the positioning groove 24 are both extended from one installation cavity 111 to another installation cavity 111. The positioning block 131 is accommodated in the positioning groove 24, and the positioning block 131 abuts against the groove wall of the positioning groove 24, and the upper top surface of the atomizer assembly 20 abuts against the lower bottom surface of the top plate 13.

[0066] Specifically, the top plate 13, the main body 11 and the base 12 are integrally manufactured, and the top plate 13, the main body 11 and the base 12 are roughly I-shaped. When the atomizer assembly 20 is installed in the installation cavity 111, the opposite ends of the atomizer assembly 20 are respectively against the top plate 13 and the base 12, so that the atomizer assembly 20 is limited, so that the atomizer assembly 20 is installed more stably. Moreover, the atomizer assembly 20 is against the main body 11 on one side facing the main body 11, which can further limit the atomizer assembly 20 and improve the connection firmness between the atomizer assembly 20 and the main bracket 10.

[0067] The positioning block 131 serves as a guide when the atomizer assembly 20 is pushed into the installation cavity 111 , thereby facilitating the user to install the atomizer assembly 20 .

[0068] In one embodiment, the top plate 13 is provided with two air guide holes 132, both ends of each air guide hole 132 pass through the top plate 13, and the air guide hole 132 passes through the end of the positioning block 131 away from the main body 11, and the atomization chamber 22 of each atomization component 20 is connected to a corresponding air guide hole 132, and the suction channel 31 can be selectively connected to a corresponding air guide hole 132 and a corresponding atomization chamber 22 of an atomization component 20.

[0069] Specifically, two air guide holes 132 are provided, and the two air guide holes 132 correspond to the atomizing chambers 22 connecting the two atomizing assemblies 20, respectively. The suction nozzle 30 is rotated so that the suction channel 31 is aligned with one of the air guide holes 132, and the smoke generated by the corresponding atomizing chamber 22 can be inhaled by the user through the air guide hole 132 and the suction channel 31. The air guide hole 132 runs through the positioning block 131. The purpose of such a setting is that when the atomizing assembly 20 is gradually pushed into the installation cavity 111 until it is completely pushed into the installation cavity 111, the air guide hole 132 is automatically aligned with the atomizing chamber 22, so that the user can install the atomizing assembly 20, reducing the steps of aligning the suction channel 31 and the air guide hole 132 before installing the atomizing assembly 20.

[0070] In some other embodiments, the size of the opening of the atomizing chamber 22 is the same as that of the air guide hole 132 to prevent smoke from remaining in the atomizing chamber 22. If smoke remains in the atomizing chamber 22, condensate will form if the smoke is not discharged for a long time, and the condensate backflow will corrode the parts inside the atomizing assembly 20.

[0071] See also Figure 3In one embodiment, each atomization assembly 20 includes an oil cup 25, an air guide tube 26, an end cover 27 and an atomization core 28. The end cover 27 is sealed and connected to the bottom of the oil cup 25. The oil cup 25 is provided with an oil storage bin 251. The air guide tube 26 is installed in the oil cup 25. The atomization chamber 22 is provided in the air guide tube 26. The atomization core 28 is installed in the atomization chamber 22. The air guide tube 26 is also provided with an oil outlet hole 261. The oil outlet hole 261 is connected to the oil storage bin 251 and the atomization chamber 22. The guide groove 21 is provided on the surface of the end cover 27 away from the oil cup 25.

[0072] Specifically, the end cap 27 is connected to the bottom of the oil cup 25 through a sealing silicone. The oil cup 25 is provided with an oil storage bin 251, and the oil storage bin 251 is provided with smoke oil. The air guide pipe 26 is installed in the oil cup 25. The inner wall of the oil cup 25 is provided with an oil outlet hole 261, and the oil outlet hole 261 is connected to the oil storage bin 251 and the air guide pipe 26. The atomizer core 28 is located on one side of the oil outlet hole 261. The smoke oil in the oil storage bin 251 enters the air guide pipe 26 through the oil outlet hole 261 and is heated by the atomizer core 28 to form smoke. The guide groove 21 and the wiring hole 23 are both provided on the surface of the end cap 27 away from the oil cup 25. One end of the wiring terminal 60 is connected to the atomizer core 28, and the other end of the wiring terminal 60 is located in the wiring hole 23. When the atomizer assembly 20 is installed in the installation cavity 111, the atomizer core 28 is electrically connected to the battery 50.

[0073] In this embodiment, the oil cup 25 serves as the outer shell of the atomizer assembly 20. The oil cup 25 abuts against the side of the main body 11, and the opposite ends of the oil cup 25 abut against the top plate 13 and the base 12 respectively. This arrangement can reduce parts such as the outer shell.
