[0049] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification is not necessarily all referring to the same embodiment, nor is it necessarily referring to a particular alternative embodiment. It will be explicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0050] It should be understood that when an element as a limitation of some element or components, it can be directly connected to the other element or component, or one or more intervening elements can exist. The terms "vertical", "horizontal", "left", "right", and similar expressions as used herein are intended for purposes of explanation and illustration and are not intended to be limiting.

[0051] Please refer to Figures 1-4 The present application provides an aerosol generating device 100, which includes an atomizer 1 and a power supply device 2. The power supply device 2 is used in combination with the atomizer 1 and can provide electric power to the atomizer 1 held in a proper position to atomize an aerosol generating substrate to generate an aerosol.

[0052] In some embodiments, the aerosol generating substrate includes a liquid substrate in a liquid state at room temperature. The liquid substrate can include a liquid containing a tobacco-containing substance including a volatile tobacco flavor component. The liquid substrate can include a liquid containing a non-tobacco substance. The liquid substrate can include water, a solvent, ethanol, a plant extract, a flavoring, a flavoring agent, or a vitamin mixture, etc. The flavoring can include areca extract, menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. The flavoring agent can include a component that can provide various flavors or tastes to a user.

The solid substrate can include a solid containing a non-tobacco substance.

[0054] In other embodiments, the aerosol generating substrate further includes a paste substrate in a paste state at room temperature.

[0055] In some embodiments, the atomizer 1 includes an atomizing wick for atomizing the liquid substrate to generate an aerosol.

[0056] The atomizing wick can include a liquid absorbing element and a heating element, and the heating element can be disposed on the liquid absorbing element. The liquid absorbing element can be a porous body for guiding the aerosol generating substrate to an atomization range of the heating element. The heating element can be used to heat the atomized aerosol generating substrate to generate an aerosol. The porous body can be a fiber such as a cotton fiber, a polypropylene fiber, a polyester fiber, or a nylon fiber, etc. The porous body can be a porous ceramic or a porous metal, and the present application does not limit the structure and composition of the porous body.

[0057] Of course, the atomizer can further include an ultrasonic element capable of generating ultrasonic waves, and the atomizer can atomize the liquid substrate using the ultrasonic waves to form the aerosol. Of course, the atomizer can further include other elements capable of atomizing the aerosol-generating substrate to form the aerosol.

[0058] In some embodiments, the atomizer 1 includes an atomizer including a heating element for heating a fixed substrate, and the heating element generates volatile substances from the solid substrate by releasing heat, thereby generating an aerosol. The heating element for heating the fixed substrate can include at least one of an external heating element, an internal heating element, and an air heating element. As used herein, the "external heating element" refers to a heating element that provides heat or radiates infrared rays outside the solid substrate to heat the fixed substrate. The "internal heating element" refers to a heating element that provides heat or radiates infrared rays inside the solid substrate to heat the fixed substrate. The "air heating element" refers to a heating element that is disposed upstream of the fixed substrate in the direction of the airflow to heat the air, and then the heated air flows into the fixed substrate to heat the solid substrate.

[0059] In some embodiments, the atomizer 1 includes a storage chamber for storing the aerosol-generating substrate. The atomizer is in fluid communication with the storage chamber, so that the atomizer can atomize the aerosol-generating substrate contained in the storage chamber.

[0060] In some embodiments, the atomizer 1 further includes an air guide tube capable of guiding the aerosol generated by the atomization of the aerosol-generating substrate by the atomizer to an air outlet of the atomizer 1, so that the aerosol flows out of the atomizer 1 through the air outlet.

[0061] In some embodiments, at least a portion of the atomizer is disposed in the air guide tube. In other embodiments, the atomizer further includes a compartment in which the atomizer is disposed, and the compartment is in fluid communication with the storage chamber through a liquid passage, so that the aerosol-generating substrate in the storage chamber can be transferred to the atomizer, and the compartment is in fluid communication with a second air guide tube, so that the aerosol formed in the compartment can be guided out by the air guide tube.

[0062] In some embodiments, the atomizer 1 further includes a liquid storage element having a large number of pores capable of absorbing a large amount of liquid substrate. The liquid storage element is disposed in the storage chamber, and at least a portion of the liquid substrate stored in the storage chamber is retained in the liquid storage element, thereby preventing the aerosol-generating substrate from leaking from the storage chamber. The liquid storage element includes, but is not limited to, one of the following materials: cotton fibers, polypropylene fibers, polyester fibers, nylon fibers, porous ceramic materials, high molecular fibers, or various combinations of the above materials.

[0063] In some embodiments, reference can be made to Figure 1, the aerosol-generating device 100 further comprises a mouthpiece 11 having an air outlet 111, at least a portion of the mouthpiece 11 being capable of being held in the mouth of a user, and the air outlet 111 being arranged to face the oral cavity of the user when the user holds the mouthpiece 11. The user sucks the aerosol generated by the atomizer 1 by sucking the mouthpiece 11.

[0064] Further, the atomizer 1 comprises the mouthpiece 11, or the mouthpiece 11 of the aerosol-generating device 100 is arranged on the atomizer 1.

[0065] In some embodiments, with reference to Figure 1 and Figure 2 , the power supply device 2 comprises a main body 21, which is configured to be connectable to at least two atomizers 1 simultaneously or to an atomization assembly.

[0066] In some embodiments, the atomization assembly comprises at least two atomizers 1, each of which has a storage cavity, and the total amount of aerosol-generating substrate that can be stored by the aerosol-generating device 100 is increased by the plurality of atomizers 1, thereby prolonging the aerosol generation time of the aerosol-generating device before a new atomizer is obtained from the outside to be used in combination with the power supply device.

[0067] In some embodiments, the total amount of aerosol-generating substrate stored in the atomization assembly is greater than 2 ml. For example, the atomization assembly comprises an atomizer 1 and a storage reservoir for storing aerosol-generating substrate, and the storage reservoir is in fluid communication with the atomizer 1 to replenish the atomizer 1 with aerosol-generating substrate. The sum of the capacity of the storage reservoir and the capacity of the atomizer 1 is greater than 2 ml. The capacity of the storage reservoir can be greater than 2 ml, for example, the capacity of the storage reservoir can be about 10 ml. The capacity of the storage reservoir can be greater than the capacity of the atomizer 1.

[0068] When the main body 21 is connectable to at least two atomizers 1 simultaneously or to an atomization assembly comprising at least two atomizers 1, the components or proportions of the aerosol-generating substrate stored in the at least two atomizers 1 can be different, thereby enabling the at least two atomizers 1 to generate aerosols of different tastes or mouthfeels. Of course, the at least two atomizers 1 can also store exactly the same aerosol-generating substrate, thereby enabling the generation of aerosols of the same taste and mouthfeel.

[0069] In some embodiments, with reference to Figure 3 and Figure 4 , the main body 21 is provided with a first accommodating cavity 213 and a second accommodating cavity 214, both of which are configured to removably receive at least a portion of an atomizer 1. The first accommodating cavity 213 is capable of holding at least one atomizer 1, and the second accommodating cavity 214 is capable of holding a number of atomizers 1 that is greater than or equal to the number of atomizers 1 that the first accommodating cavity 213 is capable of holding.

[0070] When the aerosol generating device 100 includes a plurality of atomizers 1, at least a portion of at least one atomizer 1 may be held in the first receiving cavity 213, and at least a portion of at least one atomizer 1 may be held in the second receiving cavity 214. Preferably, the plurality of atomizers 1 have substantially the same size and / or substantially the same structural features, thereby allowing the atomizers 1 held in the first receiving cavity 213 and the second receiving cavity 214 to be interchanged.

[0071] In some embodiments, the number of atomizers 1 in the aerosol generating device 100 is less than the maximum number of atomizers 1 that the first receiving cavity 213 and the second receiving cavity 214 can hold together. For example, the aerosol generating device 100 includes one atomizer, and both the first receiving cavity 213 and the second receiving cavity 214 can only hold one atomizer 1. Thus, the atomizer 1 held in the first receiving cavity 213 can be moved to the second receiving cavity 214, leaving the first receiving cavity 213 empty, or the atomizer 1 held in the second receiving cavity 214 can be moved to the first receiving cavity 213, leaving the second receiving cavity 214 empty.

[0072] In some embodiments, reference may be made to Figure 3 and Figure 4 The main body 21 also includes a first opening 215 and a second opening 216. The first opening 215 is configured to allow the atomizer 1 to be fitted into or removed from the first receiving cavity 213. The second opening 216 is configured to allow the atomizer 1 to be fitted into or removed from the second receiving cavity 214 when open. This allows at least two atomizers 1 to be individually fitted into or removed from different positions on the main body 21, thereby preventing atomizers 1 held in other positions from falling out when removing an atomizer 1 held in one position on the main body 21.

[0073] In some embodiments, reference may be made to Figures 1-4 At least one of the first opening 215 and the second opening 216 is formed on the side wall of the main body 21. For example, the second opening 216 is formed on the side wall of the main body 21, so that the atomizer 1 can be laterally fitted into the second receiving cavity 214 and held in place through the second opening 216 when the second opening 216 is open, or can be laterally removed from the second receiving cavity 214 through the second opening 216. This helps to prevent the atomizer 1 held in the second receiving cavity 214 from automatically falling out of the second receiving cavity 214 under its own weight when the second opening 216 is open, and / or helps the user to apply force to an area other than the mouthpiece 11 on the atomizer 1 to remove the atomizer 1 from the second receiving cavity 214, thereby keeping the mouthpiece 11 of the atomizer 1 clean and hygienic.

[0074] In some embodiments, referring to Figures 1-4 , the first opening 215 and the second opening 216 have different opening directions. Thus, the direction of assembling the atomizer 1 into the first accommodating cavity 213 through the first opening 215 is different from the direction of assembling the atomizer 1 into the second accommodating cavity 214 through the second opening 216, and the direction of removing the atomizer 1 from the first accommodating cavity 213 through the first opening 215 is different from the direction of removing the atomizer 1 from the second accommodating cavity 214 through the second opening 216. Also, the user can easily distinguish the first opening 215 and the second opening 216, and the user can be prevented from mistakenly identifying the first opening 215 and the second opening 216, thereby preventing the atomizer 1 from being assembled into the wrong accommodating cavity.

[0075] As an example, referring to Figure 3 and Figure 4 , the first opening 215 is opened on the proximal end of the main body 21, and the second opening 216 is opened on the sidewall of the main body 21. Further, when the atomizer 1 is retained in the first accommodating cavity 213, the mouthpiece 11 of the atomizer 1 can pass through the first opening 215 to be exposed outside the main body 21 for the user to hold the mouthpiece 11 with the mouth. Further, the user can remove the atomizer 1 from the first accommodating cavity 213 by applying a force to the mouthpiece 11 of the atomizer 1.

[0076] Alternatively, not shown, the first opening and the second opening have different opening directions, and both the first opening and the second opening are opened on the sidewall of the main body.

[0077] In some embodiments, referring to Figures 1-3 , the power supply device 2 further comprises a cover 22 connected to the main body 21 to shield the second opening 216, to prevent the atomizer 1 arranged in the second accommodating cavity 214 from being removed from the second accommodating cavity 214 through the second opening 216, and to shield the atomizer 1 in the second accommodating cavity 214 so that at least part of the atomizer 1 is hidden, and the cover 22 also helps to provide a good appearance. Wherein, the cover 22 is configured to be movable relative to the main body 21 so that the second opening 216 can be opened.

[0078] In one example, the cover 22 is configured to be removably connected to the main body 21, so that the second opening 216 can be opened by removing the cover 22 from the main body 21.

[0079] In one example, referring to Figure 1 and Figure 2 , one end of the cover 22 is connected to the main body 21, and the other end of the cover 22 is configured to be removably connected to the main body 21, so that the other end can be lifted to open the second opening 216. Thus, the second opening 216 can be opened by lifting the other end of the cover 22.

[0080] Further, it can be referred to Figure 5 The body 21 is provided with a first magnetic member 217, and the other end of the cover member 22 is provided with a second magnetic member (not shown). The first magnetic member 217 and the second magnetic member are magnetically attracted to each other, so that the other end of the cover member 22 is connected to the body 21, and the cover member 22 is kept in a position covering the second opening 216.

[0081] In some embodiments, the first magnetic member 217 comprises a magnet, and the second magnetic member comprises a metal member that can be magnetically attracted. At least a part of the metal member can be embedded in the interior of the cover member 22.

[0082] In some embodiments, the second magnetic member comprises a magnet, and the body 21 comprises a housing 212 or a support 211, at least a part of which is made of a material that can be magnetically attracted.

[0083] In some embodiments, the body 21 comprises a housing 212 and a support 211 at least partially arranged in the interior of the housing 212. The first magnetic member 217 is kept in the support 211, and the first magnetic member 217 can be covered by the housing 212.

[0084] In some embodiments, the body 21 comprises a housing 212 and a support 211 at least partially arranged in the interior of the housing 212. The cover member 22 is connected to the support 211, and the cover member 22 is substantially flush with the outer surface of the housing 212 when the cover member 22 covers the second opening 216, so that the surface of the power supply device 2 has good consistency.

[0085] In some embodiments, one end of the cover member 22 is connected to one side of the body 21, and the other end of the cover member 22 is removably connected to the other side of the body 21.

[0086] In some embodiments, at least a part of the cover member 22 is flexible and can be flipped. For example, the cover member 22 comprises a soft cover that can be flipped, and the soft cover is made of a material that can be deformed, bent or folded, for example, the soft cover can be made of leather or textile. Alternatively, the cover member 22 comprises leather or textile, so that the cover member 22 can be flipped.

[0087] In some embodiments, it can be referred to Figures 3-5 and Figure 8 The power supply device 2 further comprises a first sealing member 23 located in the second accommodating cavity 214. The first sealing member 23 is configured to elastically abut the atomizer 1 received in the second accommodating cavity 214, and seal one of the gas outlet 111 and the gas inlet 112 of the atomizer 1, so as to reduce the gas convection between the internal environment of the atomizer 1 and the external environment, and also to reduce the oxygen in the external environment from entering the storage cavity or the atomization core to oxidize the aerosol generating substrate.

[0088] Further, it can be referred to Figures 3-5 The power supply device 2 further comprises a second sealing member 24 located in the second accommodating cavity 214, the second sealing member 24 is configured to elastically abut the atomizer 1 received in the second accommodating cavity 214 and seal the other one of the air outlet 111 and the air inlet 112 of the atomizer 1. Thus, the air outlet 111 and the air inlet 112 of the atomizer 1 received in the second accommodating cavity 214 are both sealed, so as to reduce the influence of the change of the air pressure of the external environment on the air pressure inside the atomizer 1, which helps to prevent the leakage of the aerosol generating substrate in the atomizer 1, and can also prevent solid particles in the external environment from entering the inside of the atomizer 1.

[0089] In the embodiment as shown in Figure 2 The first accommodating cavity 213 can accommodate part of the atomizer 1, and the second accommodating cavity 214 can completely accommodate the atomizer 1.

[0090] In some embodiments, it can be referred to Figure 4 and Figure 5 The power supply device 2 comprises a power supply assembly 25, the power supply assembly 25 is configured to be able to provide electrical power for at least one atomizer 1, so that the atomizer 1 atomizes the aerosol generating substrate to generate aerosol.

[0091] For example, the power supply assembly 25 is configured to be able to provide electrical power for the atomizer 1 received in the first accommodating cavity 213, so that the atomizer 1 received in the first accommodating cavity 213 atomizes the aerosol generating substrate to generate aerosol. Further, the power supply assembly 25 is configured to be unable to provide electrical power for the atomizer 1 received in the second accommodating cavity 214.

[0092] The power supply device 2 further comprises a power supply, which can include any suitable battery, for example, the power supply can include a lithium battery, a disposable battery or a rechargeable battery.

[0093] In some embodiments, it can be referred to Figure 4 and Figure 5The power supply includes a first power supply 251 and a second power supply 252, which are connected in parallel. In one aspect, the parallel connection of the first power supply 251 and the second power supply 252 can increase the total power of the power supply assembly 25, which is conducive to increasing the endurance of the aerosol generating device 100, is beneficial for the aerosol generating device 100 with more aerosol generating substrate, and can avoid the power supply assembly 25 from running out of power or being insufficient before the aerosol generating substrate is consumed, or can reduce the charging frequency of the aerosol generating device 100 before the aerosol generating substrate is consumed, thereby improving the user's experience; at the same time, the parallel connection of the first power supply 251 and the second power supply 252 can provide redundancy, and when one of the power supplies fails, the other power supply can continue to provide electric power to the corresponding atomizer 1, thereby not affecting the continuous use of the aerosol generating device 100; and when the first power supply 251 and the second power supply 252 are both rechargeable power supplies, the parallel connection of the first power supply 251 and the second power supply 252 helps the first power supply 251 and the second power supply 252 have the same charging rate, which is conducive to maintaining the consistency and service life of the first power supply 251 and the second power supply 252.
