[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] Figure 1 The electronic atomization device 100 includes a housing 1, a power supply 2, a circuit board 3, an atomization unit 4, a seasoning material storage portion 5, a switch 6, a secondary heating element 7, an airflow sensor 8 and an airflow communication channel 9.

[0039] The housing 1 accommodates a power supply 2, a circuit board 3, an atomization unit 4, a switch 6, a secondary heating element 7 and an airflow sensor 8. The housing 1 is provided with a pressing portion 12, which cooperates with the switch 6 to control the on and off of the switch 6. The housing 1 is provided with a seasoning material receiving portion 5 at one end for receiving seasoning materials. A seasoning material heating element 51 is provided on the side wall of the seasoning material receiving portion 5. In this embodiment, the seasoning material is placed in an independently packaged flavor cartridge 10, and the flavor cartridge 10 is detachably received in the seasoning material receiving portion 5, so that the seasoning material can be updated by replacing the flavor cartridge 10 after consumption. In other embodiments, the seasoning material can also be directly fixed once or replaceably placed in the seasoning material receiving portion 5.

[0040] The flavoring material has a flavoring agent that increases the taste. In one embodiment, the flavoring material can be a solid material, and specifically can be tobacco or a solid material containing tobacco. The flavoring material can also be a solid material such as traditional Chinese medicine. The aerosol generating matrix can be a liquid, and specifically can be a smoke oil, etc. By providing a solid flavoring material, it can be easy to fix the flavoring material and improve the taste of the liquid aerosol generating matrix.

[0041] Optionally, in another embodiment, when the aerosol generating matrix is ​​liquid, the flavoring material may also be liquid. By providing two different types of liquids, the taste of the atomized gas can be enriched, thereby enhancing the user experience.

[0042] Alternatively, in other optional embodiments, the aerosol generating substrate and the flavoring material may be both solid materials. The embodiment of the present invention does not specifically limit the types and forms of the flavoring material and the aerosol generating substrate.

[0043] See also Figure 1 and Figure 2 , Figure 2 yes Figure 1 The power supply 2, the circuit board 3 and the switch 6 are arranged in the housing 1, the pressing part 12 is in contact with the switch 6 and exposed through the housing 1, and the pressing part 12 is used to receive the pressing force to control the switch 6 to be turned on or off.

[0044] The power source 2 provides power to the primary heating element 41 , the secondary heating element 7 and the flavoring material heating element 51 of the atomization unit 4 .

[0045] The circuit board 3 is electrically connected to the power source 2, the primary heating element 41 is electrically connected to the circuit board 3, the secondary heating element 7 and the seasoning material heating element 51 are electrically connected to the circuit board 3 via the switch 6, and the switch 6 is used to connect or disconnect the secondary heating element 7 and the seasoning material heating element 51. It is convenient to control whether the secondary heating element 7 and the seasoning material heating element 51 are working through the switch 6, so that the user can choose whether to start the secondary heating element 7 or the seasoning material heating element 51 through the pressing portion 12 according to his own taste, so as to meet the use needs of different users.

[0046] The circuit board 3 is used to control the heating of the primary heating element 41, the secondary heating element 7 and the seasoning material heating element 51. The heating circuit of the primary heating element 41 is an independently controlled heating circuit. The heating circuit of the secondary heating element 7 and the heating circuit of the seasoning material heating element 51 can be independently controlled heating circuits or simultaneously controlled heating circuits. That is, the switch connected to the secondary heating element 7 and the switch connected to the seasoning material heating element 51 can be the same switch or different switches, which is not specifically limited in the embodiment of the present invention.

[0047] The seasoning material receiving portion 5 is connected to the housing 1 , and a receiving cavity 52 is provided on the seasoning material receiving portion 5 . The seasoning material is provided in the receiving cavity 52 , so as to fix the seasoning material.

[0048] like Figure 1 and Figure 3 As shown, Figure 3 yes Figure 1 The flavor cartridge 10 is disposed in the receiving chamber 52 , and a barrier net 12 is disposed at one end of the flavor cartridge 10 facing the airflow communication channel 9 , and the barrier net 12 is used to confine the seasoning material in the flavor cartridge 10 .

[0049] In another embodiment, the barrier net 12 may also be disposed at other positions as required, such as directly disposed at the bottom of the seasoning material receiving portion 5, so as to directly place the seasoning material in the receiving cavity 52, which is not specifically limited in the embodiment of the present invention.

[0050] In one embodiment, the barrier net 12 and the seasoning material receiving portion 5 can be provided as an integral structure, for example, the barrier net 12 and the seasoning material receiving portion 5 can be integrally injection molded by injection molding. In another embodiment, the barrier net 12 and the seasoning material receiving portion 5 can also be provided as two separate components, and the barrier net 12 and the seasoning material receiving portion 5 can be detachably connected, or connected by welding or threaded connection. The embodiment of the present invention does not specifically limit the connection method of the barrier net 12 and the seasoning material receiving portion 5.

[0051] Alternatively, if Figure 1 As shown, the electronic atomization device 100 includes a flavoring material heating element 51, which is in contact with the flavoring material and is used to heat the atomized flavoring material. By providing the flavoring material heating element 51 for heating the flavoring material, the temperature of the flavoring material can be further increased, so that the ingredients in the flavoring material are fully released, so as to further improve the taste of the atomized gas.

[0052] The seasoning material heating element 51 may be in direct contact with the seasoning material, or the seasoning material heating element 51 may be in indirect contact with the seasoning material.

[0053] In one embodiment, the seasoning material heating element 51 is disposed on the inner wall of the receiving cavity 52 and surrounds the circumference of the receiving cavity 52 .

[0054] Specifically, the seasoning material heating element 51 is disposed in a continuous ring shape on the inner wall of the receiving cavity 52 so that the seasoning material in the receiving cavity 52 is heated evenly.

[0055] Optionally, the number of the seasoning material heating elements 51 may be multiple, and the multiple seasoning material heating elements 51 are evenly spaced around the inner wall of the receiving cavity 52 .

[0056] In one embodiment, if the seasoning material is directly disposed in the receiving cavity 52 , the seasoning material can be in direct contact with the seasoning material heating element 51 , thereby improving the heat conduction efficiency between the seasoning material heating element 51 and the seasoning material, and reducing the heat transfer loss of the seasoning material heating element 51 .

[0057] In another embodiment, if the flavor cartridge 10 is disposed in the receiving cavity 52, the seasoning material heating element 51 can be separated from the seasoning material, so as to protect the seasoning material heating element 51 and avoid direct contact between the seasoning material and the seasoning material heating element 51, thereby preventing more dust and dirt from being attached to the surface of the seasoning material heating element 51, reducing the heating efficiency of the seasoning material heating element 51 and wasting electric energy.

[0058] The heating temperature of the seasoning material heating element 51 is 60-65° C., so that the ingredients of the seasoning material can be volatilized slowly.

[0059] In one embodiment, the atomizing unit 4 can be detachably connected to the housing 1. Figure 1 As shown, the atomizing unit 4 includes a liquid storage chamber 42, a primary heating element 41 and an atomizing gas channel 43. The liquid storage chamber 42 stores a liquid aerosol-generating substrate at room temperature. The primary heating element 41 heats and atomizes the liquid aerosol-generating substrate, and the atomizing gas flows along the atomizing gas channel 43 to the air flow communication channel 9. By detachably connecting the atomizing unit 4 to the housing 1, the atomizing unit 4 can be easily replaced when the aerosol-generating substrate in the liquid storage chamber 42 is used up.

[0060] Alternatively, in another embodiment, the atomization unit may also be fixedly disposed in the shell. For example, the shell may be used to form a liquid storage chamber for storing an aerosol-generating matrix, so as to simplify the structure of the electronic atomization device and reduce the volume of the electronic atomization device.

[0061] The secondary heating element 7 is located in the air flow communication channel 9 between the seasoning material storage portion 5 and the atomizing gas channel 43 .

[0062] Specifically, the electronic atomization device 100 includes a connector 11, which is disposed between the atomization unit 4 and the seasoning material receiving portion 5, an air flow connecting channel 9 is disposed on the connector 11, the air flow connecting channel 9 connects the atomization gas channel 43 and the receiving chamber 52, and the secondary heating element 7 is disposed in the air flow connecting channel 9.

[0063] In one embodiment, the atomizing gas channel 43 , the airflow connecting channel 9 and the receiving chamber 52 are connected in sequence to form a closed transmission channel to prevent the atomizing gas from leaking inside the electronic atomizing device 100 .

[0064] In another embodiment, other channels or elements may be provided between the atomizing gas channel 43, the airflow communication channel 9 and the receiving chamber 52 as required, which is not specifically limited in the embodiment of the present invention.

[0065] Among them, in the transmission direction perpendicular to the airflow connecting channel 9, the cross-sectional dimensions of the atomizing gas channel 43, the cross-sectional dimensions of the airflow connecting channel 9 and the cross-sectional dimensions of the accommodating cavity 52 may be equal or unequal, and the embodiment of the present invention does not make specific limitations.

[0066] In one embodiment, if Figure 1 As shown, the transmission direction of the airflow communication channel 9 is the D direction shown in the figure, and the shape and size of the cross section of the atomized gas channel 43 are substantially the same as the shape and size of the cross section of the airflow communication channel 9, so as to enhance the air tightness of the connection between the atomized gas channel 43 and the airflow communication channel 9. The cross-sectional size of the receiving cavity 52 is larger than the cross-sectional size of the airflow communication channel 9, so as to reduce the transmission rate of the atomized gas in the receiving cavity 52, thereby prolonging the contact time and contact area between the atomized gas and the flavoring material, so that the components in the flavoring material are fully released into the atomized gas.

[0067] In this embodiment, in order to more fully heat the atomized gas, the airflow communication channel 9 is provided with a space expansion portion 91 , and the secondary heating element 7 is located in the space expansion portion 91 .

[0068] Specifically, Figure 1 As shown, in the transmission direction perpendicular to the airflow communication channel 9, the cross-sectional dimension of the space expansion part 91 is larger than the cross-sectional dimension of other parts adjacent to the space expansion part 91, and the secondary heating element 7 is arranged in the space expansion part 91. When the atomized gas is transmitted to the position of the space expansion part 91, the transmission rate of the atomized gas is reduced due to the increase in the cross-sectional dimension of the space expansion part 91. The secondary heating element 7 is arranged in the space expansion part 91, which can prolong the contact time between the atomized gas and the secondary heating element 7, thereby making the atomized gas more fully heated, so as to obtain atomized gas with higher temperature and smaller particles.

[0069] In one embodiment, the space expansion portion 91 is provided in the middle of the airflow communication channel 9. In the transmission direction perpendicular to the airflow communication channel 9, the cross-sectional dimension of the space expansion portion 91 is larger than the cross-sectional dimension of the end where the airflow communication channel 9 is connected to the atomizing gas channel 43, and is larger than the cross-sectional dimension of the end where the airflow communication channel 9 is connected to the receiving chamber 52, so as to form an airflow communication channel 9 with a large middle portion and small ends. By providing the space expansion portion 91 in the middle of the airflow communication channel 9, on the one hand, it is convenient to connect the airflow communication channel 9 with the atomizing gas channel 43, and on the other hand, it is convenient to set the cross-sectional dimension of the receiving chamber 52 to be larger than the cross-sectional dimension of the airflow communication channel 9.

[0070] In another embodiment, the space expansion portion 91 may also be disposed on the side where the airflow communication channel 9 is connected to the atomizing gas channel 43. Alternatively, in another embodiment, the space expansion portion 91 may also be disposed on the side where the airflow communication channel 9 is connected to the receiving chamber 52. The embodiment of the present invention does not specifically limit the location of the space expansion portion 91, and it may be flexibly disposed as required.

[0071] The secondary heating element 7 can be a mesh-shaped, spiral disc-shaped resistance heating sheet, or a spiral heating wire. In this embodiment, the secondary heating element 7 is a mesh heating sheet, which is perpendicular to the airflow direction.

[0072] Specifically, Figure 1 and Figure 4 As shown, Figure 4 yes Figure 1 A schematic diagram of the three-dimensional structure of the secondary heating element in FIG. The secondary heating element 7 is a mesh-shaped resistance heating sheet, and the mesh-shaped resistance heating sheet covers the airflow connecting channel 9. By providing the mesh-shaped resistance heating sheet, the contact area between the secondary heating element 7 and the atomized gas can be increased, and the atomized gas can be heated evenly. Furthermore, the plane where the resistance heating sheet is located is perpendicular to the transmission direction D of the airflow connecting channel 9. Through this arrangement, the fixing structure of the resistance heating sheet can be simplified, and the volume of the resistance heating sheet can be reduced.

[0073] In another embodiment, the plane where the resistance heating plate is located can be set to be inclined relative to the transmission direction D of the airflow connecting channel 9 to increase the area of ​​the resistance heating plate located in the airflow connecting channel 9, thereby increasing the contact area between the resistance heating plate and the atomizing gas to further increase the temperature of the atomizing gas.

[0074] In another embodiment, the resistance heating sheet can also be set to a spiral disk shape, and the plane where the resistance heating sheet is located is perpendicular to the transmission direction D of the airflow communication channel 9. Alternatively, the secondary heating element 7 can also be a spiral heating wire, and the spiral heating wire is extended along the transmission direction D of the airflow communication channel 9. Alternatively, in other optional embodiments, the secondary heating element 7 of other shapes can also be used, and the setting position of the secondary heating element 7 can be flexibly set as needed, which is not specifically limited in the embodiment of the present invention.

[0075] The mist after secondary heating can better take away the aroma of tobacco. Preferably, the temperature of the atomized gas after secondary heating is controlled within the range of 60-100 degrees Celsius; more preferably, the temperature of the atomized gas after secondary heating is controlled within the range of 60-85 degrees Celsius. The temperature of the flavoring material receiving portion 5 is preferably controlled within the range of 60-65 degrees Celsius.

[0076] The heating temperature of the secondary heating element 7 is 60-100° C., so that the temperature of the atomized gas heated by the secondary heating element 7 is 60-100° C. By controlling the temperature of the heated atomized gas to be 60-100° C., on the one hand, the components in the seasoning material can be volatilized, and on the other hand, the atomized gas temperature can be prevented from being too high, which may cause the seasoning material to have a burnt smell and affect the taste.

[0077] Furthermore, if Figure 1 and Figure 5 As shown, Figure 5 yes Figure 1 The electronic atomization device 100 includes a suction sensing component, which is used to sense the suction force to determine whether the user is using the electronic atomization device 100. When the suction sensing component senses that the user is sucking on the electronic atomization device 100, the suction sensing component generates a sensing signal. After the circuit board 3 receives the sensing signal, it further controls the atomization unit 4 to start atomizing the aerosol to generate the matrix.

[0078] Among them, Figure 1 and Figure 5 As shown, the suction sensing component includes an airflow sensor airflow channel 81 and an airflow sensor 8. The airflow sensor airflow channel 81 is connected to the airflow communication channel 9 and the airflow sensor 8, and the airflow sensor 8 is used to detect the pressure change in the airflow communication channel 9. That is, one end of the airflow sensor airflow channel 81 is connected to the airflow communication channel 9, and the other end leads to the airflow sensor 8. When the user inhales, the airflow sensor 8 transmits the sensed signal to the control circuit 3, and the control circuit 3 starts the primary heating element 41 to heat and atomize.

[0079] Specifically, when the suction force acts on the electronic atomization device 100, the pressure in the airflow connecting channel 9 will change. The airflow sensor airflow channel 81 is connected to the airflow connecting channel 9. The pressure change in the airflow connecting channel 9 causes the pressure change in the airflow sensor airflow channel 81. When the airflow sensor 8 senses the pressure change in the airflow sensor airflow channel 81, it generates a sensing signal.

[0080] Optionally, the airflow sensor 8 is arranged above the atomization unit 4 and the power supply 2 , so as to avoid being contaminated by liquid leakage from the atomization unit 4 , thereby protecting the airflow sensor 8 and improving the detection accuracy of the airflow sensor 8 .

[0081] Specifically, Figure 1 As shown, the power source 2 and the atomization unit 4 are arranged side by side to make the structure of the electronic atomization device 100 more compact. The airflow sensor 8 is arranged above the power source 2 to avoid interference between the suction sensing component and the airflow communication channel 9.

[0082] Figure 6 1 is a circuit diagram 110 of an embodiment of the present invention. The primary heating circuit 111, the secondary heating circuit 112 and the seasoning material heating circuit 113 are independent control circuits connected in parallel. The suction signal of the airflow sensor 8 and the pressing signal of the pressing part 12 are transmitted to the circuit board 3, and the control circuit on the circuit board 3 controls the heating circuit 111, the secondary heating circuit 112 and the seasoning material heating circuit 113 according to a preset strategy.

[0083] A heating control method for an electronic atomization device, the steps comprising:

[0084] When receiving the suction signal, the first heating element is activated to heat the stored liquid of the atomization unit to form atomized gas;

[0085] It is determined whether the user selects a secondary heating mode and whether to start the secondary heating element for heating, wherein the secondary heating element is arranged in an air flow communication channel between the seasoning material and the atomization unit.

[0086] Specifically, see Figure 7 , Figure 7 FIG. 1 is a flow chart of a heating control method in an embodiment of the present invention. Another aspect of the present invention further provides a heating control method, which is applied to the above-mentioned electronic atomization device 100. Figures 1 to 6 The heating control method in this embodiment is described in detail. Specifically, the heating control method includes the following steps:

[0087] Step S101: when a puff signal is received, the primary heating element of the atomization unit is started to heat the aerosol-generating substrate to form atomized gas.

[0088] Specifically, the suction sensing component arranged in the electronic atomization device 100 is used to sense the user's suction force. When the user puffs and uses the electronic atomization device 100, the suction sensing component generates a suction signal. The circuit board 3 receives the suction signal and controls the first heating element 41 of the atomization unit 4 to work to heat the atomized aerosol to generate a matrix to form atomized gas.

[0089] Alternatively, in other optional embodiments, a switch button may be provided on the electronic atomization device 100 to generate a start signal by pressing the switch button, so as to control the operation of the first heating element 41 of the atomization unit 4 to heat the atomized aerosol-generating matrix to form atomized gas. The embodiment of the present invention does not specifically limit the start method of the first heating element 41.

[0090] Step S102: Determine whether the user selects secondary heating.

[0091] Specifically, the electronic atomization device 100 determines whether the user selects secondary heating.

[0092] Step S103: If the user selects secondary heating, the secondary heating element is started to heat the atomized gas; wherein the secondary heating element is arranged in the air flow communication channel between the flavoring material and the atomization unit.

[0093] Specifically, if the electronic atomization device 100 determines that the user selects secondary heating, the control power supply 2 supplies power to the secondary heating element 7 to start the secondary heating element 7 to heat the atomized gas. The flavoring material is arranged in the airflow communication channel 9 of the electronic atomization device 100, so that the atomized gas after being heated again by the secondary heating element 7 flows through the flavoring material and then is discharged from the electronic atomization device 100 for the user to inhale. In this way, after the atomized gas with a higher temperature passes through the flavoring material, the components in the flavoring material can be fully released, and then discharged together with the atomized gas generated by the aerosol generation matrix atomization for the user to inhale, which can improve the taste of the electronic atomization device 100 and enhance the user's experience.

[0094] If the electronic atomization device 100 determines that the user has not selected secondary heating, the secondary heating element 7 is disconnected.

[0095] Among them, see Figure 8 , Figure 8 yes Figure 7 The step of judging whether the user selects secondary heating specifically includes:

[0096] Step S201: Determine whether a pressing signal is received.

[0097] The user can press the pressing portion 12 disposed on the housing 1 to trigger the switch 6 to generate a pressing signal. When the pressing portion is pressed, a pressing signal is generated, and the circuit board receives the pressing signal. When the pressing portion is not pressed, no pressing signal is generated, and the circuit board does not generate a pressing signal.

[0098] Step S202: Determine whether the secondary heating element is started.

[0099] Specifically, the electronic atomization device 100 detects whether the secondary heating element 7 is heated. If the electronic atomization device 100 detects that the secondary heating element 7 is in a heating state, the secondary heating element 7 is started. If the electronic atomization device 100 detects that the secondary heating element 7 is in a non-heating state, the secondary heating element 7 is not started.

[0100] Step S203: If a pressing signal is received and the secondary heating element is not activated, or if no pressing signal is received and the secondary heating element is activated, it is determined that the user selects secondary heating.

[0101] If in step S101, when the suction signal is received, not only the primary heating element 41 is activated, but also the secondary heating element 7 is activated at the same time, then when the primary heating element 41 atomizes the aerosol to generate the matrix, the secondary heating element 7 simultaneously heats the atomized gas formed by atomization again. At this time, if the electronic atomization device 100 does not receive a press signal and determines that the secondary heating element 7 has been activated, it is determined that the user has selected secondary heating, and the secondary heating element 7 continues to heat the atomized gas. If the electronic atomization device 100 receives a press signal and determines that the secondary heating element 7 has been activated, it is determined that the user cancels the secondary heating, and the power supply 2 stops supplying power to the secondary heating element 7 to stop heating.

[0102] If in step S101, when the suction signal is received, only the primary heating element 41 is activated, and the secondary heating element 7 is not activated. At this time, if the electronic atomization device 100 does not receive the pressing signal and determines that the secondary heating element 7 is not activated, it is determined that the user has not selected secondary heating, and the secondary heating element 7 does not heat. If the electronic atomization device 100 receives the pressing signal and determines that the secondary heating element 7 is not activated, it is determined that the user has selected secondary heating, and the secondary heating element 7 continues to heat the atomized gas.

[0103] Furthermore, the step of starting the secondary heating element 7 to heat the atomized gas includes: controlling the secondary heating element 7 to heat the atomized gas again so that the temperature of the heated atomized gas is 60-100° C. By controlling the temperature of the heated atomized gas to be 60-100° C., on the one hand, the components in the seasoning material can be volatilized, and on the other hand, the temperature of the atomized gas can be prevented from being too high, which may cause the seasoning material to have a burnt smell and affect the taste.

[0104] In one embodiment, the heating temperature of the secondary heating element 7 can be set to 60-85°C.

[0105] See also Fig. 9 , Fig. 9 FIG. 1 is a flow chart of a heating control method in another embodiment of the present invention. In this embodiment, the heating control method includes the following steps:

[0106] Step S301: When a puff signal is received, the primary heating element of the atomization unit is activated to heat the aerosol-generating substrate to form atomized gas.

[0107] Step S302: Determine whether the user selects secondary heating.

[0108] Step S303: If the user selects secondary heating, the secondary heating element is activated to heat the atomized gas; wherein the secondary heating element is disposed in the air flow communication channel between the flavoring material and the atomization unit.

[0109] Among them, step S301 to step S303 are the same as step S101 to step S103 in the above embodiment. Please refer to the description in the above embodiment and will not be repeated here.

[0110] Step S304: In response to the switch control signal, controlling the flavoring material heating element to heat the atomized flavoring material.

[0111] Optionally, in one embodiment, the switch control signal and the pressing signal can both be triggered by the pressing portion 12. Specifically, the user can press the pressing portion 12 provided on the housing 1 to simultaneously trigger the switch 6 to generate the switch control signal and the pressing signal. At this time, the switch 6 electrically connects the seasoning material heating element 51 to the circuit board 3, and the circuit board 3 electrically connects the seasoning material heating element 51 to the power source 2, thereby controlling the seasoning material heating element 51 to heat the atomized seasoning material, so as to further increase the temperature of the seasoning material, so as to facilitate the full volatilization of the ingredients in the seasoning material.

[0112] Alternatively, in another embodiment, the switch control signal and the pressing signal may also be triggered by different pressing parts, so as to control the secondary heating element 7 and the seasoning material heating element 51 separately.

[0113] Further, the step of controlling the flavoring material heating element 51 to heat the atomized flavoring material includes: controlling the temperature of the flavoring material heating element 51 to heat the atomized flavoring material to be 60-65°C.

[0114] In summary, those skilled in the art can easily understand that in the embodiment of the present invention, by arranging the secondary heating element 7 in the air flow connecting channel 9 and making the secondary heating element 7 located between the atomizing unit 4 and the flavoring material containing portion 5, the atomized gas generated by the atomizing unit 4 is transmitted through the air flow connecting channel 9. Before entering the flavoring material containing portion 5, the secondary heating element 7 can heat the cooled atomized gas again. In this way, not only can the large droplets condensed in the atomized gas be heated again to form atomized gas with small droplets, but also the temperature of the atomized gas entering the flavoring material containing portion 5 can be increased, so that the components in the flavoring material are fully released, and then discharged together with the atomized gas formed by the atomization of the aerosol generating matrix for the user to inhale. In this way, the taste of the electronic atomizing device 100 can be improved, and the user experience can be improved.
