[0002] An aerosol generating device is a device that can atomize a liquid preparation to form an aerosol. In some exemplary prior arts, the aerosol generating device includes an atomizer, in which an atomizing component and a liquid matrix are stored, and the atomizing component is used to atomize the liquid matrix to generate an aerosol.

[0003] However, the existing atomizer has a limited volume, resulting in a small amount of liquid matrix stored therein, so the atomizer must be replaced frequently or refilled with oil to supplement the insufficient liquid matrix in the atomizer. However, frequent replacement of the atomizer will result in a very high cost of using the aerosol generating device. After long-term use, the atomizer is prone to oil leakage, which will not only waste the liquid matrix, but also reduce the user experience. Utility Model Content

[0062] Please refer to Figure 1-Figure 10One embodiment of the present application provides an aerosol generating device and an atomizer 1 adapted for the aerosol generating device, the aerosol generating device comprising an atomizer 1, a container 2 and a power supply assembly 3. The atomizer 1 comprises an atomizing assembly 11 and a first shell 12, a first liquid storage chamber 121 for accommodating a liquid matrix is ​​provided inside the first shell 12, the atomizing assembly 11 is in fluid communication with the first liquid storage chamber 121, and the atomizing assembly 11 is used to atomize the liquid matrix, thereby generating an aerosol. At least a part of the atomizing assembly 11 may also be provided in the first shell 12.

[0063] The container 2 includes a second shell 21, and the second shell 21 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, so that the liquid matrix in the first liquid storage chamber 121 can be replenished by conveying 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 consumption of the liquid matrix in the first liquid storage chamber 121 by the atomizer assembly 11, thereby extending the use time of the atomizer 2 and delaying the time to replace the atomizer 2, and reducing the use cost.

[0064] Wherein, liquid matrix can comprise the liquid containing tobacco substance containing volatile tobacco flavor component, can also be the liquid comprising non-tobacco substance.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, European mint, green mint 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.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 attributes of liquid matrix, aerosol generating device can be used for different fields, such as, medical treatment, electronic aerosol atomization etc.

[0065] The liquid matrix stored in the first liquid storage chamber 121 and the second liquid storage chamber 21 may be the same liquid matrix, but is not limited thereto.

[0066] 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.

[0067] 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 .

[0068] 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.

[0069] In one embodiment, the atomization 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 capable of guiding the liquid matrix to the atomization range of the heating element 112. The heating element 112 is used to atomize at least part of the liquid matrix on the liquid absorbing element 111 to form an aerosol. The heating element 112 may be combined with the liquid absorbing element 111, so that the heating element 112 and the liquid absorbing element 111 can form a whole.

[0070] In other embodiments, the atomizing assembly 11 includes an ultrasonic atomizing assembly that can generate ultrasonic waves and can use ultrasonic waves to form aerosol from the liquid matrix. The atomizing assembly can also be other assemblies that can form aerosol from the liquid matrix, and the present application does not specifically limit the type of the atomizing assembly.

[0071] In one embodiment, the atomizer 1 is detachably connected to the power supply assembly 3, so that when the quality of the atomizer 1 decreases or when the atomizer 1 fails, the atomizer 1 can be replaced, and a new atomizer 1 is connected to the original power supply assembly 3, so that the entire aerosol generating device does not need to be discarded, thereby maintaining a good user experience of the aerosol generating device and further reducing 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.

[0072] 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 through the electrical connector 13, so that a power supply path is established 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 the 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 by abutting the two, thereby simplifying the process of separating and connecting the atomizer 1 and the power supply assembly 3.

[0073] Specifically, please refer to Figure 4-Figure 6The atomizer 1 further includes a first base 14, on which at least a portion of the electrical connector 13 is held, and a portion of the electrical connector 13 is exposed outside the first base 14, so as to facilitate electrical connection with the power supply assembly 3. The first base 14 can be connected to the first housing 12, and the first base 14 can directly or indirectly support the atomizer assembly 11, so as to hold at least a portion of the atomizer assembly 11 in 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.

[0074] In such Figure 2 and Figure 4 In the illustrated embodiment, 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 mutual 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 close to each other, the two are magnetically attracted to each other, and the electrical connector 13 and the electrode 31 of the power supply assembly 3 are stably electrically connected by magnetic attraction.

[0075] At least a portion of the first magnetic member 15 may be retained on the first base 14 .

[0076] In other embodiments, the detachable connection between the atomizer 1 and the power assembly 3 includes a snap connection or a twist connection between the atomizer 1 and the power assembly 3. Specifically, the power 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 assembly 3, at least 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, snap connection or twist connection with the first shell 12, or 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.

[0077] 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, and 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-connected to the power assembly 3. Figure 2-Figure 4 In the illustrated embodiment, 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 into the first receiving cavity 321 along the third housing 32. In other embodiments, the atomizer 1 is slidably connected to the power assembly 3 in the transverse direction, and the transverse direction is perpendicular to the longitudinal direction.

[0078] 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 together. 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, and when the container 2 and the atomizer 1 are both connected to the power supply assembly 3, the second liquid storage chamber 211 is connected to the atomization assembly 11 or the first liquid storage chamber 121 through the liquid guide channel fluid.

[0079] In one embodiment, the atomizer 1 is detachably connected to the container 2, so 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 is connected to the container 2, the second liquid storage chamber 211 is in fluid communication with the atomization assembly 11 or the first liquid storage chamber 121.

[0080] 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 fluidly 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 between the inside and outside of the second liquid storage chamber 211 is small or even no air pressure difference between the inside and outside, and 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 reduction of the liquid matrix in the second liquid storage chamber 211 will cause the air pressure and the hydraulic pressure in the second liquid storage chamber 211 to decrease, so that the pressure inside and outside the second liquid storage chamber 211 is balanced, so that 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.

[0081] 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 , so as to balance the air pressure between the first liquid storage chamber 121 and the second liquid storage chamber 211 .

[0082] Specifically, the container 2 may include a connecting portion 22, which 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 separated 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 disposed on the connecting portion 22.

[0083] In such Figure 2 and Figure 4 In the illustrated embodiment, at least a portion of the air pressure balance hole 224 is disposed 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.

[0084] 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, Figure 2 and Figure 4 In the illustrated embodiment, the connecting portion 22 includes a base 221 and a piston 222 that can move between a first position and a second position relative to the base 221. When the piston 222 is located at 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 located at 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.

[0085] For example, see Figure 2 and Figure 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.

[0086] When the piston 222 is in the first position, Figure 4, the second air pressure balance hole 2242 is staggered with the first air pressure balance hole 2241, so that the air pressure balance hole 224 is disconnected to block the gas outside the container 1 from entering the second liquid storage chamber 211. At this time, the liquid outlet hole 223 can be in a blocked state. When the minimum aperture of the liquid outlet hole 223 is less than 3mm or the minimum spacing between the two inner walls of the liquid outlet hole 223 that are opposite to each other is less than 3mm, or the liquid matrix has a large viscosity, the liquid outlet hole 223 can be in an open state. At this time, since 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.

[0087] When the piston is in the second position, you can refer to Figure 2 The first air pressure balance hole 2241 is in fluid communication with the second air pressure balance hole 2242, so that the air pressure balance hole 224 is unblocked, so that the air pressure balance hole 224 can allow the gas outside the container 2 to enter the second liquid storage chamber 211. After the gas outside the container 2 enters the second liquid storage chamber 211, the original balance between the second liquid storage chamber 211 and the outside world can be broken, so that the second liquid storage chamber 211 can be automatically discharged by the liquid outlet hole 223 under the action of hydraulic pressure. At this time, the liquid outlet hole 223 can be in an open state.

[0088] For further information, please refer to Figure 3-Figure 6 The atomizer 1 further comprises 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 against 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 at the same time, the air pressure balance hole 224 is changed from disconnected to unblocked, and 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.

[0089] exist Figure 2 In the illustrated embodiment, 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.

[0090] In one embodiment, reference may be made to Figure 4-Figure 6 The atomizer 1 includes an air guide hole 161 and a liquid inlet hole 162 which 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 the air guide hole 161 is fluidically connected to the air pressure balance hole 224.

[0091] 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, while the air pressure balance hole 224 changes from being disconnected to being unblocked, the air guide hole 161 of the atomizer 1 and the air pressure balance hole 224 of the container 2 can be fluidically connected.

[0092] In such Figure 2 , Figure 4 and Figure 6 In the illustrated embodiment, at least a portion of the liquid outlet 223 is also disposed on the connecting portion 22, and the movement of the piston 222 relative to the base 221 may have no effect on whether the liquid outlet 223 is open or not. 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.

[0093] For further information, please refer to Figure 2 and Figure 4-Figure 6 , at least part of the liquid inlet hole 162 is also arranged on the docking portion 16. Thus, when the connecting portion 22 is connected to the docking portion 16, while the air pressure balance hole 224 is changed from being disconnected to being unblocked, the liquid inlet hole 162 of the atomizer 1 and the oil storage hole 223 of the container 1 can be fluidically connected.

[0094] In such Figure 2 and Figure 4In the illustrated embodiment, 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 disposed 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 between the connecting portion 22 and the docking portion 16, the pushing portion 165 abuts against the piston 222 and pushes the piston 222 from the first position to the second position, so that the first cavity 2221 is in fluid communication with the first gas pressure balance hole 2241 through the second gas pressure balance hole 2242. At least a portion of the first hollow tube 163 is inserted into the first cavity 2221 and is interference-fitted with the piston 222, so that the connection between the outer wall of the first hollow tube 163 and the piston 222 is a sealed connection. The abutment between the pushing portion 165 and the piston 222 enables the first hollow tube 163 to occupy only a partial space of the first cavity 2221 to prevent the first hollow tube 163 from blocking the second gas guide hole 2422. When the piston 222 is in the second position, the first hollow tube 163 is in fluid communication with the second gas 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 against the piston 222 located 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 in fluid communication with the first air pressure balance hole 2241 .

[0095] Please refer to Figure 2 and Figure 4 The piston 222 also includes a second cavity, the second cavity is in fluid communication with the liquid outlet 223, or at least a portion of the second cavity is disposed in the liquid outlet 223, or at least a portion of the liquid outlet 223 is disposed in the second cavity. The docking portion 16 also 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 is interference-fitted with the piston 222, so that the connection between the outer wall of the second hollow tube 164 and the piston 222 is a sealed connection. The first cavity 2221 and the second cavity of the piston 222 are independent of each other and isolated from each other.

[0096] In one embodiment, reference may be made to Figure 2 and Figure 4The first liquid storage chamber 121 has an air flow channel 171 therein, and the air flow channel 171 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, and the atomizer also includes a pipeline connecting the suction nozzle 4 and the atomization assembly 11, the pipeline passes through the first liquid storage chamber 121, and the air flow channel 171 is arranged on the periphery of the pipeline, and the pipeline and the air flow channel 171 are isolated from each other and not connected to each other.

[0097] 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 and the nebulizer assembly 11, and the auxiliary air channel 173 connects the outside and the airflow channel 173; wherein, the air guide hole 161 is fluidly connected to the airflow channel 171, so that the gas can enter the second liquid storage chamber 211 through the auxiliary air channel 173, the airflow channel 173, the air guide hole 161 and the air pressure balance hole 224 in sequence.

[0098] The atomizer 1 includes an air inlet 18. When the aerosol generating device is inhaled, the gas enters the main airway 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 airway 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 divided and enters the main airway 172 and the auxiliary airway 173 respectively, wherein the number of the air inlet 18 can be one or more. In other examples, other air inlets can be set separately for the auxiliary airway 173 to inlet air, and the other air inlets can be set at the upper end of the first liquid storage chamber 121, or can be set near the mouthpiece 4 or set on the mouthpiece 4, so that the external gas entering the main airway 172 and the auxiliary airway 173 enters the atomizer 1 through different air inlets.

[0099] In such Figure 2 , Figure 4 and Figure 6 In the illustrated embodiment, the first liquid storage chamber 121 has a liquid storage medium 191 therein, and the liquid storage medium 191 is used to retain the liquid matrix. At least part of the liquid matrix stored in the first liquid storage chamber 121 can be retained on the liquid storage medium 191, and the liquid storage medium 191 is helpful in preventing the liquid matrix from leaking. The liquid storage medium 191 defines at least part of the boundary of the airflow channel 171.

[0100] 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, preventing the first liquid storage chamber 121 from having too low air pressure due to the consumption of liquid matrix, resulting in the atomization component 11 absorbing the liquid matrix in the first liquid storage chamber 121 at a slower speed, which is beneficial to prevent the atomization component 11 from dry burning and helps to 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 is not reduced, 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.

[0101] At the same time, the air pressure balance hole 224 is connected to the air flow channel 171 through a fluid, so that the first liquid storage chamber 121 is connected to the second liquid storage chamber 211 by air flow, so that when the user inhales the aerosol generating device, the external gas can enter the air pressure balance hole 224 through the auxiliary air channel 173 and the air flow channel 171, so that the container 2 can automatically supply the liquid matrix to the atomizer 1 when the user inhales, so the operation of the container 2 supplying the liquid matrix is ​​simple. At the same time, it can also prevent the liquid matrix from being supplied to the atomizer 1 when the user is not inhaling, prevent the atomizer 1 from leaking oil due to excessive liquid storage, and prevent the first liquid storage chamber 121 from being overloaded.

[0102] Specifically, the liquid storage medium 191 can define at least part of the boundary of the airflow channel 171. For example, a channel is provided inside the liquid storage medium 191, and the size of the channel is such that the liquid matrix cannot block it, and the channel constitutes at least part of the airflow channel 171. For example, the longitudinal length of the liquid storage medium 191 is smaller than the longitudinal length of the first liquid storage cavity 121, so that there is a gap between the upper end of the liquid storage medium 191 (the end close to the suction nozzle 4) and the upper end of the first liquid storage cavity 121, and the gap constitutes at least part of the airflow channel. For example, reference can be made to Figure 6 The liquid storage medium 191 has a groove 1911 on its side wall. When the liquid storage medium 191 is accommodated in the first liquid storage cavity 121, part of the side wall of the liquid storage medium 191 abuts against the cavity wall of the first liquid storage cavity 121. The groove 1911 on the side wall of the liquid storage medium 191 forms a gap between the side wall of the liquid storage medium 191 and the cavity wall of the first liquid storage cavity 121, and the gap constitutes at least a part of the airflow channel.

[0103] In such Figure 2 , Figure 4 and Figure 6In the illustrated embodiment, the atomizer 1 further includes hard cotton 192, the hardness of the hard cotton 192 is greater than the hardness of the liquid storage medium 191, and the liquid storage medium 191 can absorb liquid cotton, and its density is less than the density of the hard cotton 192, so that the liquid absorption speed and liquid transfer speed of the hard cotton 192 are both less than the liquid absorption speed and liquid transfer speed of the liquid storage medium 191. The hard cotton 192 supports the liquid storage medium 191 to keep 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. Conducting 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 airway 173, for example Figure 4 and Figure 6 As shown, the partial outer side surface of the hard cotton 192 abuts against the wall of the first liquid storage cavity 121, and there is a gap a between the partial outer side surface and the first liquid storage cavity 121, and the gap a constitutes at least a part of the auxiliary airway 173; 4. The hard cotton 192 defines at least a part of the boundary of the airflow channel 171, for example Figure 4 and Figure 6 As shown, a partial outer side surface of the hard cotton 192 abuts against the cavity wall of the first liquid storage cavity 121 , and a gap b is provided between the partial outer side surface and the first liquid storage cavity 121 , and the gap b constitutes at least a portion of the airflow channel 171 .

[0104] The liquid absorption speed and liquid transfer speed 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 leakage of the liquid matrix in the atomizer 1 .

[0105] Please refer to Figure 2 and Figure 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, and 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.

[0106] Further, the atomizer 1 includes a holder 20, which defines at least part of the boundary of the first liquid storage chamber 121, and at least part of the side wall of the holder 20 is the cavity wall of the first liquid storage chamber 121. The holder 20 also includes a base 201, and the base 201 supports a part of the bottom of the hard cotton 192, so that the hard cotton 192 is retained in the holder 20, and a gap c is provided between the base 201 and the bottom of the hard cotton 192, and the gap c forms a part of the auxiliary airway 173. Specifically, the base 201 has a groove 2011, so that there is a gap c between the base 201 and the bottom of the hard cotton 192.

[0107] The docking portion 16 and the retaining member 20 may be integrally formed. Figure 3 In the illustrated embodiment, a protrusion 202 is provided on the inner wall of the side wall of the retaining member 20, and the protrusion 202 abuts against a portion of the outer wall of the hard cotton 192 and a portion of the outer wall of the liquid storage medium 191, so that a channel (including a gap b) for fluid communication with the first liquid storage chamber 121 and for gas to pass through is provided between the side wall of the retaining member 20 and the outer side surface of the hard cotton 192. The protrusion 202 is disposed adjacent to the end of the air guide hole 161, so that the air guide hole 161 can be in fluid communication with the gas in the first liquid storage chamber 121 through the channel.

[0108] Preferably, you can refer to Figure 2 The liquid inlet hole 162 is arranged below the air guide hole 161 to prevent the liquid matrix in the second liquid storage chamber 224 from being excessively retained in the container 2 and unable to be introduced into the liquid inlet hole 162 .

[0109] In such Figure 7 In the embodiment shown, the outer side wall of the hard cotton 192 adjacent to the air guide hole 161 has a first channel 1921, and the first channel 1921 defines a portion of the boundary of the gap b. The outer side wall of the hard cotton 192 adjacent to the groove 2011 of the bottom bracket 201 has a second channel 1922, and the second channel 1922 defines a portion of the boundary of the gap a.

[0110] In one embodiment, reference may be made 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 container 2 completes the injection of the liquid matrix, at least a part of the sealing plug 23 is arranged in the oil injection hole 2212 to seal the oil injection hole 2212 to prevent the liquid matrix in the second liquid storage chamber 211 from leaking through the oil injection hole 2212.

[0111] In one embodiment, the connection between the atomizer 1 and the power assembly 3 is detachably connected, and the container 2 is also detachably connected to the power assembly 3. Therefore, after the container 2 is separated from the power assembly 3, the container 1 can be refilled with oil to replenish the liquid matrix in the second liquid storage chamber 211, so that the container 2 can be used repeatedly, reducing the use cost of the aerosol generating device, or the container 2 can be replaced.

[0112] In one embodiment, during the use of the aerosol generating device, the atomizer 1 can be first connected to the container 2, so that the liquid outlet hole 223 on the container 2 is fluidly connected to the oil inlet 162 on the atomizer 1, and the air pressure balance hole 224 on the container 2 is fluidly connected to the air guide hole 161 on the atomizer 1, and 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; and 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 transformed into a complete form and can be used and inhaled by the user.

[0113] 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 in the second shell 21.
