Aerosol generating devices and nebulizers

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 202410210939.4, filed with the Patent Office of China on February 26, 2024, entitled “Aerosol Generating Device and Atomizer,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The embodiments of the present application relate to the technical field of aerosol generation, and in particular to an aerosol generating device and an atomizer. Background Art

[0004] An aerosol generating device is a device that can atomize a liquid formulation to form an aerosol. In some exemplary prior arts, the aerosol generating device includes an atomizer, wherein the atomizer is provided with an atomizing component and stores a liquid matrix, and the atomizing component is used to atomize the liquid matrix to generate an aerosol.

[0005] However, existing atomizers have limited capacity, resulting in a small amount of liquid matrix stored within them. Therefore, the atomizer must either be frequently replaced or refilled with oil to replenish the insufficient liquid matrix within the atomizer. However, frequent atomizer replacement results in a very high cost of using the aerosol generating device. After long-term use, the atomizer is prone to oil leakage, which not only wastes the liquid matrix but also reduces the user experience.

[0006] Application Contents

[0007] The purpose of this application is to provide an aerosol generating device and an atomizer, which can reduce the frequency of replacing the atomizer, reduce the cost of use and improve the user experience.

[0034] When the container is located at the fourth position, the atomizer is connected to the container, and the second liquid storage chamber is in fluid communication with the atomizer.

[0035] As an example, the power supply assembly has a receiving cavity for at least partially accommodating the container and / or the atomizer, and an interference member is disposed in the receiving cavity for removably retaining the container and / or the atomizer in the receiving cavity.

[0036] As an example, the combination direction of the atomizer and the container is substantially perpendicular to the combination direction of the container and / or the atomizer and the power supply assembly.

[0037] As an example, the second housing is further configured to establish an air path through which air can flow between the second liquid storage chamber and the first liquid storage chamber when the second housing is connected to the first housing.

[0038] An embodiment of the present application provides an atomizer, comprising:

The container is configured to be connected to the atomizer assembly and establish a liquid path for liquid flow between the second liquid storage chamber and the first liquid storage chamber, so that the liquid matrix in the second liquid storage chamber can be transferred to the first liquid storage chamber. The power supply assembly is used to provide power for the atomizer assembly to atomize the liquid matrix; wherein the atomizer and the power supply assembly are detachably electrically connected, and when the atomizer and the power supply assembly are connected, a power supply path is established between the atomizer assembly and the power supply assembly. Thus, the container can supply liquid matrix to the atomizer to supplement the shortage of liquid matrix in the atomizer or reduce the consumption rate of liquid matrix in the atomizer, thereby delaying the service life of the atomizer and reducing the replacement frequency of the atomizer. At the same time, the atomizer can be separated from the power supply assembly, so that the atomizer can be replaced when the quality deteriorates due to long-term use or when a failure occurs. While maintaining a good user experience of the aerosol generating device, the power supply assembly can also continue to be used, thereby further reducing the use cost of the aerosol generating device.

[0061] Referring to Figures 1-10 , one embodiment of the present application provides an aerosol generating device and an atomizer 1 adapted for use therewith. The aerosol generating device includes the atomizer 1, a container 2, and a power supply assembly 3. The atomizer 1 includes an atomizer assembly 11 and a first housing 12. The first housing 12 includes a first liquid storage chamber 121 for accommodating a liquid matrix. The atomizer assembly 11 is in fluid communication with the first liquid storage chamber 121 and is configured to atomize the liquid matrix, thereby generating an aerosol. At least a portion of the atomizer assembly 11 may also be disposed within the first housing 12.

[0062] The container 2 includes a second shell 21, which has a second liquid storage chamber 211 for storing a liquid matrix. When the aerosol generating device is in a complete form, the container 2 can be combined with the atomizer 1, and the second liquid storage chamber 211 is in fluid communication with the atomizer 1 to supply the liquid matrix to the atomizer assembly 11 or the first liquid storage chamber 121. This allows the liquid matrix in the first liquid storage chamber 121 to be replenished by delivering the liquid matrix to the first liquid storage chamber 121, or the liquid matrix can be directly supplied to the atomizer assembly 11 to slow down the atomizer assembly 11's consumption of the liquid matrix in the first liquid storage chamber 121, thereby extending the use time of the atomizer 2 and delaying the time to replace the atomizer 2, thereby reducing the cost of use.

[0063] Wherein, the liquid matrix can comprise the liquid containing tobacco substance that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco substance.The liquid matrix can comprise water, liquid medicine, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture etc., and spices can comprise betel nut extract, menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide various fragrance or local flavor to the user.The vitamin mixture can be the mixture that is mixed with at least one in vitamin A, vitamin B, vitamin C and vitamin E, but is not limited to this.Based on the different properties of liquid matrix, aerosol generating device can be used for different fields, such as, medical treatment, electronic aerosol atomization etc.

[0064] The liquid matrix stored in the first liquid storage chamber 121 and the second liquid storage chamber 21 can be the same liquid matrix, but is not limited thereto.

[0065] In one embodiment, the first liquid storage chamber 121 can accommodate a maximum of 2 ml of liquid matrix, and the second liquid storage chamber 21 can accommodate a maximum of 10 ml of liquid matrix. It should be noted that when the first liquid storage chamber 121 can accommodate a maximum of 2 ml of liquid matrix, the volume of the first liquid storage chamber 121 is greater than or equal to 2 ml, and when the second liquid storage chamber 21 can accommodate a maximum of 10 ml of liquid matrix, the volume of the second liquid storage chamber 21 is greater than or equal to 10 ml.

[0066] In one embodiment, the volume of the first liquid storage chamber 121 is less than or equal to the volume of the second liquid storage chamber 21 .

[0067] In one embodiment, the total volume of the liquid matrix contained in the first liquid storage chamber 121 and the second liquid storage chamber 21 does not exceed 12 ml. It should be noted that in this embodiment, the sum of the volumes of the first liquid storage chamber 121 and the second liquid storage chamber 21 may be greater than or equal to 12 ml.

[0068] In one embodiment, the atomizer assembly 11 includes a liquid absorbing element 111 and a heating element 112. The liquid absorbing element 111 may be a porous body or fiber, capable of absorbing a liquid matrix and directing the liquid matrix into the atomization range of the heating element 112. The heating element 112 is configured to atomize at least a portion of the liquid matrix on the liquid absorbing element 111 to form an aerosol. The heating element 112 may be integrated with the liquid absorbing element 111 so that the heating element 112 and the liquid absorbing element 111 form a single unit.

[0069] In other embodiments, the atomizing assembly 11 includes an ultrasonic atomizing assembly that can generate ultrasonic waves and can use ultrasonic waves to form aerosols from the liquid matrix. The atomizing assembly can also be other components that can form aerosols from the liquid matrix, and this application does not specifically limit the type of atomizing assembly.

[0070] In one embodiment, the atomizer 1 is detachably connected to the power supply assembly 3. Therefore, if the quality of the atomizer 1 deteriorates or if the atomizer 1 malfunctions, the atomizer 1 can be replaced by connecting a new atomizer 1 to the original power supply assembly 3, thereby avoiding the need to discard the entire aerosol generating device. This maintains a good user experience of the aerosol generating device and further reduces the cost of use. When the atomizer 1 is connected to the power supply assembly 3, a power supply path can be established between the atomizer assembly 11 and the power supply assembly 3.

[0071] Based on this, the atomizer 1 also includes an electrical connector 13, one end of which is electrically connected to the atomizer assembly 11, and the other end of the electrical connector 13 is exposed to facilitate electrical connection with the power supply assembly 3. The atomizer assembly 11 is electrically connected to the power supply assembly 3 via the electrical connector 13, thereby establishing a power supply path between the atomizer assembly 11 and the power supply assembly 3, and the atomizer assembly 11 can obtain power provided by the power supply assembly 3 through this power supply path. Preferably, when the atomizer 1 is connected to the power supply assembly 3, the electrical connector 13 abuts against the electrode 31 of the power supply assembly 3, and the electrical connection between the atomizer assembly 11 and the power supply assembly 3 is achieved through the abutment between the two, thereby simplifying the process of separating and connecting the atomizer 1 and the power supply assembly 3.

[0072] Specifically, referring to Figures 4-6 , the atomizer 1 further includes a first base 14. At least a portion of the electrical connector 13 is retained on the first base 14, and a portion of the electrical connector 13 is exposed outside the first base 14 to facilitate electrical connection with the power supply assembly 3. The first base 14 can be connected to the first housing 12 and can directly or indirectly support the atomizer assembly 11, thereby retaining at least a portion of the atomizer assembly 11 within the first housing 12. When the atomizer 1 is connected to the power supply assembly 3, the power supply assembly 3 can support the first base 14.

[0073] In the embodiments shown in Figures 2 and 4 , the detachable connection between the atomizer 1 and the power supply assembly 3 includes the atomizer 1 and the power supply assembly 3 being connected to each other by magnetic attraction. Specifically, the atomizer 1 includes a first magnetic member 15, and the power supply assembly 3 includes a second magnetic member 36. When the first magnetic member 15 and the second magnetic member 36 are in proximity, they are magnetically attracted to each other, thereby maintaining a stable electrical connection between the electrical connector 13 and the electrode 31 of the power supply assembly 3 through magnetic attraction.

[0074] At least a portion of the first magnetic member 15 may be retained on the first base 14 .

[0075] In other embodiments, the detachable connection between the atomizer 1 and the power supply assembly 3 includes a snap connection or a twist connection between the atomizer 1 and the power supply assembly 3. Specifically, the power supply assembly 3 includes a power supply 33 and a third shell 32. The power supply 33 can be any suitable battery or battery cell. The power supply 33 is arranged inside the third shell 32. The third shell 32 extends to form a first receiving chamber 321. When the atomizer 1 is connected to the power supply assembly 3, at least a part of the atomizer 1 is located in the first receiving chamber 321. An interference member is provided on the third shell 32 or in the first receiving chamber 321. The interference member can interfere with the atomizer 1 in the first receiving chamber 321, for example, by snap connection or twist connection with the first shell 12, or by snap connection or twist connection with the first base 14, so that the atomizer 1 can be removably arranged in the first receiving chamber 321.

[0076] In one embodiment, before the atomizer 1 is electrically connected to the power assembly 3, the atomizer 1 is slidably connected to the power assembly 3. When the atomizer 1 slides relative to the power assembly 3 until the electrical connector 13 corresponds to the electrode 31 of the power assembly 3, the atomizer 1 is magnetically connected or snap-fitted to the power assembly 3. In the embodiment shown in Figures 2-4, the atomizer 1 is slidably connected to the power assembly 3 in the longitudinal direction, so that at least a portion of the atomizer 1 slides along the third housing 32 into the first receiving cavity 321. In other embodiments, the atomizer 1 is slidably connected to the power assembly 3 in the transverse direction, with the transverse direction being perpendicular to the longitudinal direction.

[0077] In one embodiment, the atomizer 1 and the container 2 are connected to each other to form an inseparable whole, so that when the atomizer 1 is replaced, the container 2 is replaced along with it. Based on this, when the atomizer 1 is connected to the power supply assembly 3, the container 2 can be spaced apart from the power supply assembly 3 so that there is no direct connection between the container 2 and the power supply assembly 3, or the container 2 can be detachably connected to the power supply assembly 3. As an example, a liquid guide channel is provided in the power supply assembly 3. When both the container 2 and the atomizer 1 are connected to the power supply assembly 3, the second liquid storage chamber 211 is fluidically connected to the atomizing assembly 11 or the first liquid storage chamber 121 through the liquid guide channel.

[0078] In one embodiment, the atomizer 1 and the container 2 are detachably connected, so that the second housing 21 and the first housing 12 are independent of each other, and the atomizer 1 and the container 2 are separable, so that the atomizer 1 can be replaced separately, so that the container 2 can be retained when the atomizer 1 is replaced. When the atomizer 1 and the container 2 are connected, the second liquid storage chamber 211 is in fluid communication with the atomizing assembly 11 or the first liquid storage chamber 121.

[0079] Based on this, as an example, the container 2 includes a liquid outlet 223 and an air pressure balance hole 224. When the atomizer 1 is connected to the container 2, the liquid outlet 223 fluid connects the second liquid storage chamber 211 with the atomizing assembly 11 or the first liquid storage chamber 121, and the second liquid storage chamber 211 supplies the liquid matrix to the atomizing assembly 11 or the first liquid storage chamber 121 through the liquid outlet 223. If the gas outside the container 2 can enter the second liquid storage chamber 211 through the air pressure balance hole 224, the difference in air pressure inside and outside the second liquid storage chamber 211 is small or even no air pressure difference inside and outside. Under the hydraulic pressure of the liquid matrix in the second liquid storage chamber 211, the liquid matrix in the second liquid storage chamber 211 can be automatically introduced into the first liquid storage chamber 121 or the atomizing assembly 11 through the liquid outlet 223. If no gas enters the second liquid storage chamber 211 through the air pressure balance hole 224, the liquid matrix in the second liquid storage chamber 211 decreases, which causes both the air pressure and the hydraulic pressure in the second liquid storage chamber 211 to decrease, thereby balancing the pressure inside and outside the second liquid storage chamber 211. As a result, the liquid matrix in the second liquid storage chamber 211 cannot be discharged from the second liquid storage chamber 211 through the liquid outlet hole 223, and leakage of the liquid matrix in the second liquid storage chamber 211 can be prevented.

[0080] In one embodiment, the air pressure balance hole allows gas to flow between the first liquid storage chamber 121 and the second liquid storage chamber 211 , thereby balancing the air pressure between the first liquid storage chamber 121 and the second liquid storage chamber 211 .

[0081] Specifically, the container 2 may include a connecting portion 22 that is detachably connected to the atomizer 1. When the atomizer 1 is connected to the container 2, the connecting portion 22 is connected to the atomizer 1. After the atomizer 1 is separated from the container 2, the connecting portion 22 is detached from the atomizer 1. At least a portion of the air pressure balance hole 224 and / or at least a portion of the liquid outlet hole 223 is provided on the connecting portion 22.

[0082] In the embodiment shown in Figures 2 and 4, at least a portion of the air pressure balance hole 224 is provided on the connecting portion 22, so that the gas outside the container 2 can enter the second liquid storage chamber 221 through the air pressure balance hole 224 after flowing through the atomizer 1. Specifically, the gas in the first liquid storage chamber 121 can enter the second liquid storage chamber 221 through the air pressure balance hole 224.

[0083] In order to prevent the liquid matrix in the container 2 from leaking through the air pressure balance hole 224 and the liquid outlet hole 223 before being connected to the atomizer 1, in the embodiment shown in Figures 2 and 4, the connecting portion 22 includes a base 221 and a piston 222 that can move relative to the base 221 between a first position and a second position. When the piston 222 is in the first position, the air pressure balance hole 224 is closed, and the gas outside the container 2 cannot enter the second liquid storage chamber 221 through the air pressure balance hole 224. When the piston 222 is in the second position, the air pressure balance hole 224 is opened, so that the gas outside the container 2 cannot enter the second liquid storage chamber 221 through the air pressure balance hole 224.

[0084] For example, referring to Figures 2 and 4, the air pressure balance hole 224 includes a first air pressure balance hole 2241 set on the base 221 and a second air pressure balance hole 2242 set on the piston 222, and one of the first air pressure balance hole 2241 and the second air pressure balance hole 2242 maintains fluid communication with the second liquid storage chamber 211.

[0085] When the piston 222 is in the first position, as shown in FIG. 4 , the second pressure balance hole 2242 is staggered from the first pressure balance hole 2241, disconnecting the pressure balance hole 224 to prevent gas outside the container 1 from entering the second liquid storage chamber 211. At this time, the liquid outlet hole 223 may be in a blocked state. If the minimum diameter of the liquid outlet hole 223 is less than 3 mm, or the minimum spacing between the two opposing inner walls of the liquid outlet hole 223 is less than 3 mm, or the liquid matrix has a relatively high viscosity, the liquid outlet hole 223 may be in an open state. At this time, because the liquid tension of the liquid matrix and the external air pressure are approximately equal to the sum of the air pressure and the hydraulic pressure in the second liquid storage chamber 211, the liquid matrix in the second liquid storage chamber 211 cannot leak through the oil guide port 223.

[0086] When the piston is in the second position, as shown in FIG. 2 , the first pressure balance hole 2241 is in fluid communication with the second pressure balance hole 2242, allowing the pressure balance hole 224 to be unobstructed. This allows gas from outside the container 2 to enter the second liquid storage chamber 211. Once the gas from outside the container 2 enters the second liquid storage chamber 211, it disrupts the original equilibrium between the second liquid storage chamber 211 and the outside world, allowing the liquid from the second liquid storage chamber 211 to be automatically discharged through the liquid outlet hole 223 under the action of hydraulic pressure. At this point, the liquid outlet hole 223 may be open.

[0087] Further, referring to Figures 3 to 6, the atomizer 1 also includes a docking portion 16. When the atomizer 1 is connected to the container 2, the connecting portion 22 is connected to the docking portion 16, and preferably the connection between the connecting portion 22 and the docking portion 16 is detachably connected. During the connection between the connecting portion 22 and the docking portion 16, the docking portion 16 abuts the piston 222 and pushes the piston 223 from the first position to the second position, so that the air pressure balance hole 224 is changed from disconnected to unblocked. Thus, when the connection between the atomizer 1 and the container 2 is completed, the connecting portion 22 is connected to the docking portion 16, and the air pressure balance hole 224 is changed from disconnected to unblocked. There is no need to perform other operations to make the air pressure balance hole 224 change from disconnected to unblocked after the atomizer 1 is connected to the container 2.

[0088] In the embodiment shown in FIG. 2 , when the container 2 is connected to the atomizer 1 , at least a portion of one of the docking portion 16 and the connecting portion 22 may be embedded in the other.

[0089] In one embodiment, referring to Figures 4 to 6, the atomizer 1 includes an air guide hole 161 and a liquid inlet hole 162 that is fluidically connected to the atomizing assembly 11 or the first liquid storage chamber 121. When the atomizer 1 is connected to the container 2, the liquid inlet hole 162 is fluidically connected to the liquid outlet hole 223, and at the same time, the air guide hole 161 is fluidically connected to the air pressure balance hole 224.

[0090] Among them, the air guide hole 161 can be set on the docking part 16, so that when the connecting part 22 is connected to the docking part 16, the air guide hole 161 of the atomizer 1 and the air pressure balance hole 224 of the container 2 can be fluidically connected while the air pressure balance hole 224 changes from being disconnected to being unblocked.

[0091] In the embodiments shown in Figures 2, 4, and 6, at least a portion of the liquid outlet 223 is also provided on the connecting portion 22. Movement of the piston 222 relative to the base 221 may have no effect on the conduction of the liquid outlet 223. When the connecting portion 22 is connected to the atomizer 1, the liquid outlet 223 on the connecting portion 22 is in fluid communication with the liquid inlet 162 of the atomizer 1.

[0092] 2 and 4 to 6 , at least a portion of the liquid inlet 162 is also provided on the docking portion 16. Thus, when the connecting portion 22 is connected to the docking portion 16, the air pressure balance hole 224 is unblocked, and the liquid inlet 162 of the atomizer 1 and the oil storage hole 223 of the container 1 can be in fluid communication.

[0093] In the embodiment shown in Figures 2 and 4, the base 221 has a slide 225 inside, the first air pressure balance hole 2241 maintains fluid communication with the second liquid storage chamber 211, the piston 222 can be movably arranged in the slide 225, and the piston 222 has a first cavity 2221 inside that is fluidly connected to the second air pressure balance hole 2242. When the piston 222 is in the first position, the communication path between the second air pressure balance hole 2242 and the second liquid storage chamber 211 is disconnected. The docking portion 16 includes a first hollow tube 163 and a pushing portion 165. During the connection process between the connecting portion 22 and the docking portion 16, the pushing portion 165 abuts the piston 222 and pushes the piston 222 from the first position to the second position, thereby establishing fluid communication between the first cavity 2221 and the first pressure balance hole 2241 through the second pressure balance hole 2242. At least a portion of the first hollow tube 163 is inserted into the first cavity 2221 and forms an interference fit with the piston 222, resulting in a sealed connection between the outer wall of the first hollow tube 163 and the piston 222. The abutment between the pushing portion 165 and the piston 222 allows the first hollow tube 163 to occupy only a portion of the first cavity 2221, preventing the first hollow tube 163 from blocking the second air guide hole 2422. When the piston 222 is in the second position, the first hollow tube 163 is in fluid communication with the second pressure balance hole 2242 through the remaining first cavity 2221. A stopper 2211 may also be provided on the base 221 , and the stopper 2211 is used to abut the piston 222 at the second position to prevent the second air pressure balance hole 2242 from being pushed by the docking portion 16 to a position exceeding the position where the fluid is connected to the first air pressure balance hole 2241 .

[0094] 2 and 4 , the piston 222 further includes a second cavity, which is in fluid communication with the liquid outlet 223, or at least a portion of the second cavity is disposed within the liquid outlet 223, or at least a portion of the liquid outlet 223 is disposed within the second cavity. The docking portion 16 further includes a second hollow tube 164. During the connection between the connecting portion 22 and the docking portion 16, the piston 222 is pushed from the first position to the second position, and at least a portion of the second hollow tube 164 is inserted into the second cavity and forms an interference fit with the piston 222, such that the connection between the outer wall of the second hollow tube 164 and the piston 222 is sealed. The first cavity 2221 and the second cavity of the piston 222 are independent of each other and isolated from each other.

[0095] In one embodiment, referring to Figures 2 and 4, the first liquid storage chamber 121 has an air flow channel 171, which connects the upper and lower ends of the first liquid storage chamber 121, so that the air pressure at the upper and lower ends of the first liquid storage chamber 121 is balanced, wherein the upper end of the first liquid storage chamber 121 is the end close to the suction nozzle 4, and the lower end of the first liquid storage chamber 121 is arranged opposite to its lower end. The atomizer also includes a pipe connecting the suction nozzle 4 and the atomizing assembly 11, the pipe passes through the first liquid storage chamber 121, and the air flow channel 171 is arranged on the periphery of the pipe, and the pipe and the air flow channel 171 are isolated from each other and not connected to each other.

[0096] The nebulizer 1 also has a main air channel 172 and an auxiliary air channel 173. The main air channel 172 fluid connects the outside world and the atomizing assembly 11, and the auxiliary air channel 173 connects the outside world and the air flow channel 173; wherein, the air guide hole 161 is fluidly connected to the air flow channel 171, so that the gas can enter the second liquid storage chamber 211 through the auxiliary air channel 173, the air flow channel 173, the air guide hole 161 and the air pressure balance hole 224 in sequence.

[0097] The atomizer 1 includes an air inlet 18. When the aerosol generating device is inhaled, the gas enters the main air channel 172 through the air inlet 18, and then enters the mouthpiece 4 in sequence through the atomizing assembly 11 and the pipe. As an example, when the aerosol generating device is inhaled, the gas also enters the auxiliary air channel 173 through the air inlet 18, that is, the external gas can enter the atomizer 1 through the same air inlet 18, and then the gas is diverted to enter the main air channel 172 and the auxiliary air channel 173 respectively, wherein the number of air inlet holes 18 can be one or more. In other examples, other air inlets can be provided separately for the auxiliary air channel 173 to intake air. The other air inlets can be provided at the upper end of the first liquid storage chamber 121, or can be provided near the mouthpiece 4 or on the mouthpiece 4, so that the external gas entering the main air channel 172 and the auxiliary air channel 173 enters the atomizer 1 through different air inlets.

[0098] In the embodiments shown in Figures 2, 4, and 6, the first liquid storage chamber 121 includes a liquid storage medium 191. The liquid storage medium 191 is used to retain the liquid matrix. At least a portion of the liquid matrix stored in the first liquid storage chamber 121 can be retained on the liquid storage medium 191. The liquid storage medium 191 helps prevent leakage of the liquid matrix. The liquid storage medium 191 defines at least a portion of the boundary of the airflow channel 171.

[0099] The auxiliary air channel 173 fluid connects the outside world and the air flow channel 171, so that the outside gas can enter the first liquid storage chamber 121, thereby balancing the air pressure of the first liquid storage chamber 121, and preventing the first liquid storage chamber 121 from having too low an air pressure due to the consumption of the liquid matrix, which causes the atomizer assembly 11 to absorb the liquid matrix in the first liquid storage chamber 121 at a slower rate, which helps prevent the atomizer assembly 11 from dry burning and helps ensure that the atomizer 1 can provide a sufficient amount of aerosol. Under normal circumstances, when the liquid matrix in the first liquid storage chamber 121 has not decreased, the air pressure inside and outside the first liquid storage chamber 121 is roughly balanced, and the outside gas cannot enter the first liquid storage chamber 121 through the auxiliary air channel 173. Therefore, the outside gas enters the first liquid storage chamber 121 through the auxiliary air channel 173 mainly when the user inhales the aerosol generating device.

[0100] At the same time, the air pressure balance hole 224 is fluidically connected to the air flow channel 171, establishing air flow communication between the first liquid storage chamber 121 and the second liquid storage chamber 211. Therefore, when a user draws on the aerosol generating device, external gas can enter the air pressure balance hole 224 through the auxiliary air channel 173 and the air flow channel 171, allowing the container 2 to automatically supply liquid matrix to the atomizer 1 when the user draws on the aerosol generating device. This simplifies the operation of supplying liquid matrix from the container 2. Furthermore, the container 2 can prevent the atomizer 1 from being supplied with liquid matrix when the user is not drawing on the aerosol, thereby preventing the atomizer 1 from leaking due to excessive liquid storage and preventing overloading of the first liquid storage chamber 121.

[0101] Specifically, the liquid storage medium 191 can define at least a portion of the airflow channel 171. For example, the liquid storage medium 191 may have a channel defined within it, the channel being dimensioned so that the liquid matrix cannot block it, and the channel forming at least a portion of the airflow channel 171. For example, the longitudinal length of the liquid storage medium 191 may be less than the longitudinal length of the first liquid storage chamber 121, such that a gap exists between the upper end of the liquid storage medium 191 (the end proximal to the nozzle 4) and the upper end of the first liquid storage chamber 121, and the gap forming at least a portion of the airflow channel. For example, referring to FIG. 6 , the sidewalls of the liquid storage medium 191 may have a groove 1911. When the liquid storage medium 191 is contained in the first liquid storage chamber 121, a portion of the sidewall of the liquid storage medium 191 abuts against the wall of the first liquid storage chamber 121. The groove 1911 on the sidewall of the liquid storage medium 191 forms a gap between the sidewall of the liquid storage medium 191 and the wall of the first liquid storage chamber 121, and the gap forming at least a portion of the airflow channel.

[0102] In the embodiments shown in Figures 2, 4, and 6, the atomizer 1 further includes hard cotton 192. The hardness of the hard cotton 192 is greater than that of the liquid storage medium 191. The liquid storage medium 191 can absorb liquid. The density of the hard cotton 192 is less than that of the hard cotton 192. As a result, the liquid absorption and liquid transfer speeds of the hard cotton 192 are both lower than those of the liquid storage medium 191. The hard cotton 192 supports the liquid storage medium 191 to retain the liquid storage medium 191 in the first liquid storage chamber 121. The hard cotton 192 extends to the end of the liquid inlet hole 162 and blocks the end of the liquid inlet hole 162. The functions of the hard cotton 192 include: 1. transferring at least part of the liquid matrix in the liquid inlet hole 162 to the liquid storage medium 191 for storage; 2. isolating the air guide hole 161 and the liquid inlet hole 162; 3. The hard cotton 192 defines at least part of the boundary of the auxiliary air channel 173. For example, as shown in Figures 4 and 6, the local outer side surface of the hard cotton 192 abuts the cavity wall of the first liquid storage cavity 121, and there is a gap a between the local outer side surface and the first liquid storage cavity 121, and the gap a constitutes at least part of the auxiliary air channel 173; 4. The hard cotton 192 defines at least part of the boundary of the airflow channel 171. For example, as shown in Figures 4 and 6, the local outer side surface of the hard cotton 192 abuts the cavity wall of the first liquid storage cavity 121, and there is a gap b between the local outer side surface and the first liquid storage cavity 121, and the gap b constitutes at least part of the airflow channel 171.

[0103] The liquid absorption and liquid transfer speeds of the hard cotton 192 are both lower than those of the liquid storage medium 191 , which helps prevent the container 2 from supplying too much liquid matrix to the atomizer 1 per unit time, and helps prevent the liquid matrix in the atomizer 1 from leaking.

[0104] 2 and 4 , the hard cotton 192 and the atomizer assembly 11 are spaced apart from each other, and the atomizer assembly 11 is directly connected to the liquid storage medium 191 , so that the atomizer assembly 11 can directly absorb the liquid matrix on the liquid storage medium 191 but cannot directly absorb the liquid matrix on the hard cotton 192 . At least part of the liquid matrix of the hard cotton 192 is mainly transferred to the atomizer assembly 11 through the liquid storage medium 191, thereby preventing the atomizer assembly 11 from leaking the liquid matrix.

[0105] Furthermore, the atomizer 1 includes a retainer 20, which defines at least a portion of the boundary of the first liquid storage chamber 121. At least a portion of the sidewalls of the retainer 20 serve as the walls of the first liquid storage chamber 121. The retainer 20 also includes a base 201, which supports a portion of the bottom of the hard cotton 192. While the hard cotton 192 is retained in the retainer 20, a gap c is defined between the base 201 and the bottom of the hard cotton 192. The gap c forms a portion of the auxiliary airway 173. Specifically, the base 201 has a groove 2011, thereby defining a gap c between the base 201 and the bottom of the hard cotton 192.

[0106] The docking portion 16 and the retaining member 20 can be integrally formed. In the embodiment shown in Figure 3 , a protrusion 202 is formed on the inner sidewall of the retaining member 20. The protrusion 202 abuts against portions of the outer sidewall of the hard cotton 192 and the outer sidewall of the liquid storage medium 191, creating a channel (including a gap b) between the sidewall of the retaining member 20 and the outer side of the hard cotton 192 that is fluidly connected to the first liquid storage chamber 121 and allows gas to pass through. The protrusion 202 is positioned adjacent to the end of the air guide hole 161, allowing the air guide hole 161 to communicate with the gas in the first liquid storage chamber 121 through this channel.

[0107] Preferably, referring to FIG. 2 , the liquid inlet 162 is disposed below the air guide hole 161 to prevent excessive liquid matrix in the second liquid storage chamber 224 from being retained in the container 2 and unable to be introduced into the liquid inlet 162 .

[0108] In the embodiment shown in FIG7 , the outer side wall of the hard cotton 192 adjacent to the air guide hole 161 has a first channel 1921, which defines a portion of the boundary of the gap b, and the outer side wall of the hard cotton 192 adjacent to the groove 2011 of the bottom bracket 201 has a second channel 1922, which defines a portion of the boundary of the gap a.

[0109] In one embodiment, referring to FIG. 9 , the container 2 is provided with a sealing plug 23 and an oil injection hole 2212 in fluid communication with the second liquid storage chamber 211. The oil injection device injects the liquid matrix into the second liquid storage chamber 211 through the oil injection hole 2212. After the liquid matrix is ​​injected into the container 2, at least a portion of the sealing plug 23 is disposed in the oil injection hole 2212 to seal the oil injection hole 2212 and prevent the liquid matrix in the second liquid storage chamber 211 from leaking through the oil injection hole 2212.

[0110] In one embodiment, the connection between the atomizer 1 and the power supply assembly 3 is detachable, and the container 2 is also detachably connected to the power supply assembly 3. Therefore, after the container 2 is separated from the power supply assembly 3, the container 1 can be refilled to replenish the liquid matrix in the second liquid storage chamber 211, allowing the container 2 to be used repeatedly, reducing the cost of using the aerosol generating device, or the container 2 can be replaced.

[0111] In one embodiment, during use of the aerosol generating device, the atomizer 1 can be first connected to the container 2 so that the liquid outlet 223 on the container 2 is fluidically connected to the oil inlet 162 on the atomizer 1, and the air pressure balance hole 224 on the container 2 is fluidically connected to the air guide hole 161 on the atomizer 1. At the same time, the air pressure balance hole 224 is switched from a disconnected state to a unblocked state, so that the container 2 and the atomizer 1 are joined to form a whole; then the whole is connected to the power supply assembly 3, so that the electrical connector 13 of the atomizer 1 is electrically connected to the electrode 31 of the power supply assembly 3, and the aerosol generating device is thus completed and can be used and inhaled by the user.

[0112] In one embodiment, the container 2 further includes a second base 24, which is connected to the second shell 21 and supports the connecting portion 22, so that at least a portion of the connecting portion 22 is retained within the second shell 21. An oil filling hole 2212 is defined on the base 221 of the connecting portion 22, and the sealing plug 23 is connected to the base 221. After the second base 24 is connected to the second shell 21, the second base 24 can cover the oil filling hole 2212, thereby concealing the oil filling hole 2212.

[0113] In the embodiments shown in Figures 2 and 4 , the removable connection between the container 2 and the power supply assembly 3 includes the container 2 and the power supply assembly 3 being connected to each other through mutual magnetic attraction. Specifically, the container 2 includes a third magnetic member 25, and the power supply assembly 3 includes a fourth magnetic member 37. When the third magnetic member 25 and the fourth magnetic member 37 are in close proximity, they are magnetically attracted to each other, thereby maintaining a stable connection between the container 2 and the power supply assembly 3 through magnetic attraction.

[0114] At least a portion of the third magnetic component 25 can be retained on the second base 24 .

[0115] In other embodiments, the detachable connection between the container 2 and the power supply assembly 3 includes a snap-on connection or a twist-on connection between the container 2 and the power supply assembly 3. Specifically, the third shell 32 extends to form a second receiving cavity 322. When the container 2 and the power supply assembly 3 are connected, at least a portion of the container 2 is located in the second receiving cavity 322. An interference member is provided on the third shell 3 or in the second receiving cavity 322. The interference member can interfere with the container 2 in the second receiving cavity 322. For example, the third shell 32 is snap-on connected or twist-on connected to the second shell 21, or snap-on connected or twist-on connected to the second base 23, so that the container 2 can be removably disposed in the first receiving cavity 321.

[0116] In one embodiment, before the container 2 is connected to the power supply assembly 3, the container 2 and the power supply assembly 3 are slidably connected. When the container 2 slides to a predetermined position relative to the power supply assembly 3, the container 2 and the power supply assembly 3 are magnetically connected or snap-fitted. In the embodiment shown in FIG2-4 , the container 2 is slidably connected to the power supply assembly 3 in the longitudinal direction, so that at least a portion of the container 2 slides into the second receiving cavity 322.

[0117] In other embodiments, the container 2 is slidably connected to the power supply assembly 3 in a transverse direction, with the transverse direction being perpendicular to the longitudinal direction. For example, the power supply assembly 3 includes a guide rail, and the container 2 is configured to slide along the guide rail from a third position to a fourth position when connected to the power supply assembly 3. When the container 2 is in the fourth position, the atomizer 1 is connected to the container 2, and the second liquid storage chamber 211 is in fluid communication with the atomizer 1.

[0118] The first receiving cavity 321 and the second receiving cavity 322 may be interconnected, and may have a clear boundary line between them, or may not have a clear boundary line between them. Of course, a partition plate may also be provided between the first receiving cavity 321 and the second receiving cavity 322 to separate them from each other.

[0119] In one embodiment, when the atomizer 1 is connected to the container 2, the first shell 12 and the second shell 21 can be connected to each other and the connection between the two is detachably connected. The detachable connection between the first shell 12 and the second shell 21 can be a snap connection. For example, referring to Figures 5, 8 and 9, one of the first shell 12 and the second shell 21 has a cam 26, and the other has a barb or a slot 27. When the atomizer 1 is connected to the container 2, the cam 26 is snap-connected with the barb or the slot 27, and the first shell 12 and the second shell 21 are detachably fixed to each other. Of course, the connection between the first shell 12 and the second shell 21 can also be detachably connected by magnetic attraction or magnetic repulsion, so that the two are abutted against each other by magnetic attraction or magnetic repulsion.

[0120] In one embodiment, when the atomizer 1 is connected to the container 2, the first base 14 and the second base 24 can be connected to each other and the connection between the two is detachable. The detachable connection between the first base 14 and the second base 24 can be a snap connection. For example, referring to Figures 2 and 4, the first base 14 is provided with a protruding first elastic arm 141, the first elastic arm 141 is provided with a first hook 142, and the second base 24 is provided with a snap convex 241. When the atomizer 1 is connected to the container 2, at least a portion of the first elastic arm 141 is inserted into the interior of the second base 24, and the first hook 142 is snap-connected with the snap convex 241. Of course, the connection between the first base 14 and the second base 24 can also be detachably connected by magnetic attraction or magnetic repulsion, so that the two are abutted against each other by magnetic attraction or magnetic repulsion.

[0121] In one embodiment, referring to Figures 2 and 4, an air inlet 35 is provided on the third shell 32, and the air inlet 35 is fluidically connected to the first receiving chamber 321. After the atomizer 1 is connected to the power supply assembly 3, the air inlet 35 is fluidically connected to the atomizer 1. During inhalation, the outside air passes through the air inlet 35, the first receiving chamber 321, and the air inlet hole 18 of the atomizer 1 in sequence and enters the main air channel 172 and the auxiliary air channel 173.

[0122] Furthermore, the power supply assembly 3 also includes an airflow sensor 34, which is fluidically connected to the air inlet 18 of the atomizer 1. When the user inhales the aerosol generating device, the airflow or air pressure at the position of the airflow sensor 34 will change. The airflow sensor 34 can determine that the user is inhaling the aerosol generating device based on the change in the airflow or air pressure, and then can control the power supply 33 to provide power to the atomizer 1, so that the atomization assembly 11 atomizes the liquid matrix.

[0123] In one embodiment, referring to Figures 2 and 3 , the direction in which the atomizer 1 and the container 2 are assembled is substantially perpendicular to the direction in which the container 2 and / or the atomizer 1 and the power supply assembly 3 are assembled. For example, the direction in which the atomizer 1 and the container 2 are assembled is substantially horizontal, and the direction in which the container 2 and / or the atomizer 1 and the power supply assembly 3 are assembled is substantially vertical.

[0124] In one embodiment, referring to Figures 1 and 3 , the aerosol generating device further includes a mouthpiece 4, which is in fluid communication with the atomizing assembly 11 and the main airway 172. A user inhales the aerosol generated by the atomizer 1 into the oral cavity by suctioning on the mouthpiece 4. The atomizer 1 can be detachably connected to the mouthpiece 4, and the container 2 can be detachably connected to the mouthpiece 4. In the embodiment shown in Figure 3 , the atomizer 1 includes the mouthpiece 4, i.e., the mouthpiece 4 is a component of the atomizer 1.

[0125] In one embodiment, the second shell 21 is also configured to establish an air path for air flow between the second liquid storage chamber 211 and the first liquid storage chamber 121 when combined and connected with the first shell 12, and the air pressure balance hole 224 and the air guide hole 161 are at least part of the air path.
