The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0039] In one embodiment, an aerosol generating device is provided. The atomizing substrate used in the aerosol generating device is a heat-not-burn cigarette cartridge. The heat-not-burn cigarette cartridge only includes the tobacco section of the traditional heat-not-burn cigarette cartridge, and does not include the hollow cooling section and the mouthpiece section of the traditional heat-not-burn cigarette cartridge. The heat-not-burn cigarette cartridge is shorter than the traditional heat-not-burn cigarette cartridge and has a lower cost, thereby reducing the user's use cost. In addition, the aerosol generating device is a movable or detachable structure. In the open state, the user can insert or remove the atomizing substrate from the installation port of the second atomizing shell, and the replacement of the atomizing substrate is relatively convenient.

[0040] Please refer to Figures 1 to 6 The aerosol generating device of this embodiment mainly includes a first atomizing shell 1, a second atomizing shell 2 and an atomizing core assembly 3. The first atomizing shell 1 and the second atomizing shell 2 are connected in a movable or detachable manner. For example, in this embodiment, the first atomizing shell 1 and the second atomizing shell 2 are connected in a reversible rotational manner. In other embodiments, the first atomizing shell 1 and the second atomizing shell 2 may be connected in a sliding manner, a plug-in separation manner, etc., so that the first atomizing shell 1 and the second atomizing shell 2 can be moved relative to each other to replace the atomizing matrix 7.

[0041] In this embodiment, the first atomizing shell 1 can be flipped over to be closed and opened relative to the second atomizing shell 2, and the first atomizing shell 1 and the second atomizing shell 2 have a combined state and an open state; in the combined state, the first atomizing shell 1 and the second atomizing shell 2 are closed and docked, and the first atomizing shell 1 covers the atomizing core assembly 3 in the second atomizing shell 2; in the open state, the first atomizing shell 1 and the second atomizing shell 2 are separated, and the atomizing core assembly 3 in the second atomizing shell 2 is exposed, and in this state, the atomizing matrix 7 can be inserted into the atomizing core assembly 3, and the atomizing matrix 7 in the atomizing core assembly 3 can be taken out.

[0042] The first atomizing shell 1 is an upper cover structure. A suction nozzle 11 is provided at one end of the first atomizing shell 1. An axially penetrating air outlet passage 12 is provided inside the first atomizing shell 1. The air outlet passage 12 extends from one end of the first atomizing shell 1 facing away from the suction nozzle 11 to the suction nozzle 11, that is, the suction nozzle 11 is connected to the air outlet passage 12.

[0043] The first atomizing shell 1 may be an integrated structure, and the nozzle 11 and the air outlet channel 12 are formed by integral injection molding. The first atomizing shell 1 may also be composed of a plurality of components, for example, the first atomizing shell 1 includes a main body and a nozzle, the nozzle is fixedly connected to the main body by plugging, threading, etc., and the air outlet channel 12 runs through the connected main body and nozzle.

[0044] In this embodiment, the second atomizing shell 2 is the main body of the aerosol generating device. The second atomizing shell 2 may be a shell of an integrated structure, or may be composed of a plurality of shells.

[0045] The second atomizing shell 2 has an end face facing the first atomizing shell 1, and the end face can be a plane. The second atomizing shell 2 has an end face facing the first atomizing shell 1, and correspondingly, the end face of the second atomizing shell 2 can also be a plane, that is, the end face of the second atomizing shell 2 facing away from the suction nozzle 11 is a plane. The first atomizing shell 1 and the second atomizing shell 2 are provided with corresponding end faces, so that when the first atomizing shell 1 and the second atomizing shell 2 are combined, they can be butted through the planar end faces, which can improve the stability of the combined connection of the first atomizing shell 1 and the second atomizing shell 2, and can also improve the airtightness of the combined connection of the first atomizing shell 1 and the second atomizing shell 2.

[0046] The end surface of the second atomizing shell 2 facing the first atomizing shell 1 is provided with a mounting opening 21, and a receiving cavity 22 is further provided inside the second atomizing shell 2. When the second atomizing shell 2 is not in the state of the atomizing core assembly 3, the mounting opening 21 is communicated with the receiving cavity 22. The mounting opening 21 can be a round hole or a square hole, and the inner diameter of the mounting opening 21 is slightly larger than the outer diameter of the atomizing matrix 7, so that the atomizing matrix 7 can be taken in and out through the mounting opening 21.

[0047] The atomizing core assembly 3 is fixedly installed in the accommodating cavity 22 of the second atomizing shell 2. The atomizing core assembly 3 has an atomizing cavity 31. One end of the atomizing cavity 31 has an opening and the other end has an air inlet. The opening of the atomizing cavity 31 is axially aligned and communicated with the mounting port 21. The atomizing cavity 31 can be a cylindrical cavity, and the central axis of the atomizing cavity 31 is colinear with the central axis of the mounting port 21. The user can insert the atomizing matrix 7 into the atomizing cavity 31 through the mounting port 21, and the user can also take out the atomizing matrix 7 in the atomizing cavity 31 from the mounting port 21.

[0048] The atomizing chamber 31 is used for inserting and accommodating the atomizing substrate 7 and for heating the atomizing substrate 7 to form smoke.

[0049] An air inlet is provided on the side or bottom of the second atomizing shell 2 , and the air inlet, the accommodating chamber 22 , the air inlet hole of the atomizing chamber 31 and the atomizing chamber 31 are sequentially connected, so that external air can enter the atomizing chamber 31 .

[0050] The depth of the atomizing chamber 31 is equal to or slightly greater than the length of the atomizing matrix 7. For example, when the atomizing matrix 7 is 10-14 mm, the depth of the atomizing chamber 31 is 10-15 mm, so that the entire atomizing matrix 7 can be accommodated in the atomizing chamber 31. The atomizing chamber 31 heats the entire atomizing matrix 7, which is beneficial to improving the heating atomization efficiency.

[0051] In this embodiment, the atomization core assembly 3 may include a heating tube 3a and a heating body 3b. The heating tube 3a is a tubular structure. The interior of the heating tube 3a has an atomization chamber 31. The heating body 3b is a resistance heating structure. The heating body 3b may be a resistance heating sheet. The resistance heating sheet may be applied to the circumferential outer side or inner side of the heating tube 3a. After the resistance heating sheet is energized, it can convert electrical energy into thermal energy to heat the heating tube 3a, so as to heat the atomization matrix 7 in the atomization chamber 31.

[0052] In other embodiments, the atomizer core assembly 3 may also include a heating tube and an electromagnetic induction coil, wherein the interior of the heating tube has an atomization chamber 31, and the electromagnetic induction coil is disposed around the circumferential outer side of the heating tube, and the heating tube is an electromagnetic heating structure, that is, the heating tube is a metal tube that can be heated by electromagnetic induction, such as a copper tube. When the electromagnetic induction coil is energized, electromagnetic induction heating can be achieved on the heating tube to achieve heating of the atomization matrix 7 in the atomization chamber 31.

[0053] In this embodiment, the atomizer core assembly 3 further includes a mounting seat 3c, which is fixed in the accommodating cavity 22 in the second atomizer shell 2 by means of snap connection or the like, and the heating tube 3a is mounted on the mounting seat 3c.

[0054] In this embodiment, a mounting groove 23 is provided on the edge of one end of the second atomizing shell 2 facing the first atomizing shell 1, and a rotating shaft 24 is installed in the mounting groove 23. An axially protruding connecting portion 13 is provided on the edge of one end of the first atomizing shell 1 facing the second atomizing shell 2. The connecting portion 13 is provided with a connecting hole. The rotating shaft 24 is passed through the mounting hole of the connecting portion 13 to realize the rotational connection between the first atomizing shell 1 and the second atomizing shell 2.

[0055] The first atomizing shell 1 is rotatably connected to the second atomizing shell 2 via a rotating shaft 24 , and the first atomizing shell 1 can be connected to the second atomizing shell 2 and opened and separated by turning over.

[0056] The installation groove 23 can hide the rotating shaft 24, so that when the first atomizing shell 1 and the second atomizing shell 2 are combined, the outer wall of the first atomizing shell 1 and the outer wall of the second atomizing shell 2 are perfectly butted against each other, which is more beautiful.

[0057] In other embodiments, the rotating shaft 24 is mounted on the first atomizing shell 1 , and the second atomizing shell 2 is provided with a corresponding mounting hole, so that the first atomizing shell 1 and the second atomizing shell 2 can also be rotatably connected.

[0058] In this embodiment, the first atomizing shell 1 and the second atomizing shell 2 of the aerosol generating device can be flipped to a combined state and an open state;

[0059] Please refer to Figure 1 and Figure 3 In the assembled state, the end face of the first atomizing shell 1 fits with the end face of the second atomizing shell 2, and the air outlet channel 12 of the first atomizing shell 1 is aligned and connected with the mounting port 21 of the second atomizing shell 2, so that after the atomizing matrix 7 in the atomizing chamber 31 is heated to form smoke, it can reach the nozzle through the mounting port 21 and the air outlet channel 12 for use by the user.

[0060] Please refer to Figure 2 In the open state, the first atomizing shell 1 is flipped open relative to the second atomizing shell 2, and the mounting port 21 of the second atomizing shell 2 is exposed and not covered by the first atomizing shell 1; in this state, the user can flip the aerosol generating device, and the volume of the atomizing matrix 7 will shrink after being heated and used, so the atomizing matrix 7 in the atomizing chamber 31 can be poured out by lightly shaking the flipped aerosol generating device; of course, the user can also use tools such as tweezers to clamp out the atomizing matrix 7; after taking out the used atomizing matrix 7, a new atomizing matrix 7 can be directly inserted into the atomizing chamber 31.

[0061] The aerosol generating device of the present embodiment has a first atomizing shell 1 provided with a suction nozzle 11 which can be connected to the atomizing chamber 31. The suction nozzle 11 can replace the suction nozzle section of the traditional heat-not-burn cigarette cartridge. The suction nozzle 11 is a part of the first atomizing shell. The atomizing matrix 7 is installed in the atomizing chamber 31 of the second atomizing shell 2. The suction nozzle 11 is separated from the atomizing matrix 7. The heat energy generated by heating the atomizing matrix 7 is difficult to transfer to the suction nozzle 11, and the hollow cooling section of the traditional heat-not-burn cigarette cartridge can be omitted, so that the atomizing matrix 7 including only the tobacco segment can be installed in the atomizing chamber of the present aerosol generating device, which greatly reduces the user's use cost; and the first atomizing shell 1 and the second atomizing shell 2 can be movably connected. In the open state, the user can insert or remove the atomizing matrix 7 from the mounting port 21 of the second atomizing shell 2, which facilitates the replacement of the atomizing matrix 7.

[0062] Please refer to Figure 3 In one embodiment, the air outlet channel 12 of the first atomizing shell 1 includes a first air outlet channel 121 and a second air outlet channel 122 connected in series, an end of the first air outlet channel 121 away from the second air outlet channel 122 is used to dock with the mounting port 21, and an end of the second air outlet channel 122 away from the first air outlet channel 121 extends to the suction nozzle 11.

[0063] The inner diameter of the first air outlet channel 121 is larger than the inner diameter of the atomization chamber 31, and the inner diameter of the second air outlet channel 122 is smaller than the inner diameter of the atomization chamber 31. The inner wall area of ​​the first air outlet channel 121 is larger than the inner wall area of ​​the second air outlet channel 122. The first air outlet channel 121 forms a cooling channel with a larger space, so that the smoke discharged from the atomization chamber 31 first enters the first air outlet channel 121 for cooling, then enters the second air outlet channel 122, and finally reaches the user's mouth, which can prevent the user from being scalded by overly hot smoke.

[0064] The inner diameter of the second gas outlet channel 122 is smaller than the inner diameter of the atomization chamber 31 , which can also prevent the atomized matrix 7 in the atomization chamber 31 from leaking out of the second gas outlet channel 122 .

[0065] In other embodiments, the air outlet channel 12 includes more than three channels connected in series, and the inner diameter of the channel closer to the installation port 21 is larger. A cooling inner wall close to the installation port 21 can also be added to cool the smoke.

[0066] Please refer to Figure 3In one embodiment, a sealing member 4 is provided in the second atomizing shell 2. The sealing member 4 may be a silicone elastic structure. One end of the atomizing core assembly 3 close to the mounting port 21 is connected to the second atomizing shell 2 through the sealing member 4. The sealing member 4 is squeezed between the inner wall of the second atomizing shell 2 and the end of the heating tube 3a of the atomizing core assembly 3. The sealing member 4 seals the connection between the mounting port 21 and the atomizing chamber 31 to prevent the mist outlet port of the atomizing chamber 31 from being connected to the accommodating chamber 22 of the second atomizing shell 2, thereby preventing the smoke generated by the atomizing chamber 31 from entering the accommodating chamber 22 of the second atomizing shell 2.

[0067] The sealing member 4 may be provided with a connection structure such as an annular slot, and the end of the heating tube 3 a is sealedly connected to the connection structure such as the annular slot of the sealing member 4 .

[0068] In other embodiments, an annular slot is provided on the inner side of the mounting opening 21 of the second atomizing shell 2, and the end of the heating tube 3a is inserted into the annular slot by interference fit to form a sealed connection, which can also seal the connection between the mounting opening 21 and the atomizing chamber 31 to prevent the smoke generated by the atomizing chamber 31 from entering the accommodating chamber 22 of the second atomizing shell 2.

[0069] Please refer to Figure 6 In one embodiment, the seal 4 may be provided with a radially protruding limiting portion 41, which may be a protruding hemispherical structure or a triangular structure. The limiting portion 41 is located on the path of the atomizing substrate 7 inserted into the atomizing chamber 31, and when the atomizing substrate 7 is located in the atomizing chamber 31, the limiting portion 41 abuts against the end of the atomizing substrate 7. The limiting portion 41 of the seal 4 can fix the atomizing substrate 7 in the atomizing chamber 31, avoid the shaking of the atomizing substrate 7 in the atomizing chamber 31, and improve the stability of the atomizing substrate 7 insertion.

[0070] In other embodiments, a radially protruding limiting portion is provided in the atomizing chamber 31, that is, a protruding limiting portion is provided on the inner wall of the heating tube 3a, which can also improve the stability of the insertion of the atomizing matrix 7.

[0071] In one embodiment, the rotating shaft 24 can be a damping rotating shaft, and a certain external force needs to be applied to realize the flipping of the first atomizing shell 1 relative to the second atomizing shell 2, so that when the first atomizing shell 1 is in a combined state relative to the second atomizing shell 2, the first atomizing shell 1 will not be accidentally turned over, and when the first atomizing shell 1 is in an open state relative to the second atomizing shell 2, the first atomizing shell 1 will not be accidentally closed. The provision of the damping rotating shaft can improve the safety of the use of the aerosol generating device, and is conducive to the convenient replacement of the atomizing matrix 7.

[0072] In other embodiments, the rotating shaft 24 is connected to a rotational damping structure. For example, a radially protruding rib is provided in the mounting hole of the connecting portion 13 of the first atomizing shell 1, and the rib is pressed against the rotating shaft 24. This structure can generate a damping force on the first atomizing shell 1 relative to the second atomizing shell 2, thereby realizing a damped rotational connection between the first atomizing shell 1 and the second atomizing shell 2, and can also improve the safety of the use of the aerosol generating device, and facilitate the replacement of the atomizing matrix 7.

[0073] Please refer to Figure 7 In one embodiment, one end of the first atomizing shell 1 facing the second atomizing shell 2 is provided on the first limiting portion 14, and one end of the second atomizing shell 2 facing the first atomizing shell 1 is provided with the second limiting portion 25, the first limiting portion 14 and the second limiting portion 25 are correspondingly arranged, the first limiting portion 14 and the second limiting portion 25 can be magnetic blocks with different magnetic properties, or one of the first limiting portion 14 and the second limiting portion 25 is a magnetic block, and the other is a magnetizable metal block, and the first limiting portion 14 and the second limiting portion 25 can generate magnetic attraction when they are close to each other.

[0074] In the combined state, the magnetic attraction formed between the first limiting portion 14 and the second limiting portion 25 can fix the first atomization shell 1 relative to the second atomization shell 2, thereby preventing the first atomization shell 1 from being accidentally opened, thereby ensuring the safety of the aerosol generating device in the combined state.

[0075] In other embodiments, one of the first limiting portion 14 and the second limiting portion 25 is a buckle, and the other is a slot. The first limiting portion 14 and the second limiting portion 25 can form a detachable snap connection, and can also prevent the first atomization shell 1 from being accidentally flipped open, thereby ensuring the safety of the aerosol generating device in the combined state.

[0076] Please refer to Figure 8 In one embodiment, an electronic aerosol generating device is provided. The difference between the electronic aerosol generating device and any of the above embodiments is that it also includes a circuit board 5 and a battery 6.

[0077] The electronic aerosol generating device of this embodiment comprises a circuit board 5, a battery 6 and an aerosol generating device in any of the above embodiments.

[0078] The circuit board 5 and the battery 6 are installed in the accommodating cavity 22 of the second atomizer shell 2. The circuit board 5 is electrically connected to the battery 6 and the atomizer core assembly 3 respectively. The circuit board 5 can be electrically connected to the heating body 3b of the atomizer core assembly 3 through a cable.

[0079] A charging socket may be provided at one end of the second atomizing shell 2 away from the first atomizing shell 1 or at the side of the second atomizing shell 2 . The charging socket is electrically connected to the circuit board 5 . The charging socket may be connected to a mobile power source or mains electricity to replenish power for the battery 6 .

[0080] The electronic aerosol generating device of the present embodiment has a first atomizing shell 1 provided with a nozzle 11 which can be connected to the atomizing chamber 31. The nozzle 11 can replace the nozzle section of a conventional heat-not-burn cigarette cartridge. The nozzle 11 is a part of the first atomizing shell. The atomizing matrix 7 is installed in the atomizing chamber 31 of the second atomizing shell 2. The nozzle 11 is separated from the atomizing matrix 7. The heat energy generated by heating the atomizing matrix 7 is difficult to transfer to the nozzle 11. The hollow cooling section of the conventional heat-not-burn cigarette cartridge can be omitted, so that the atomizing matrix 7 including only a tobacco section can be installed in the atomizing chamber of the present aerosol generating device, thereby greatly reducing the user's usage cost. In addition, the first atomizing shell 1 and the second atomizing shell 2 can be movably connected. In the open state, the user can insert or remove the atomizing matrix 7 from the mounting port 21 of the second atomizing shell 2, thereby facilitating the replacement of the atomizing matrix 7.
