The secondary heating element 7 is a mesh-shaped resistance heating sheet which is covered in the air flow communication passage 9. Through setting up netted resistance heating piece, can promote the area of contact of secondary heating element 7 with atomizing gas to can make atomizing gas be heated evenly. Further, the plane of the resistance heating sheet is perpendicular to the conveying direction D of the airflow communication channel 9. Through the arrangement mode, the fixing structure of the resistance heating sheet can be simplified, and the volume of the resistance heating sheet can be reduced.

In another embodiment, the plane of the resistance heating sheet may be inclined with respect to the transmission direction D of the air flow communication channel 9 to increase the area of the resistance heating sheet in the air flow communication channel 9, and further increase the contact area between the resistance heating sheet and the atomizing air to further increase the temperature of the atomizing air.

In yet another embodiment, the resistance heating sheet may be further provided in a spiral disk shape, and the plane of the resistance heating sheet is perpendicular to the conveying direction D of the airflow communication channel 9. Alternatively, the secondary heating element 7 may be a spiral heating wire extending in the conveying direction D of the air flow communication passage 9. Or, in other optional embodiments, the secondary heating element 7 with other shapes may also be adopted, and the setting position of the secondary heating element 7 may be flexibly set as required, and the embodiment of the present invention is not particularly limited.

Preferably, the temperature of the atomized gas after secondary heating is controlled within the range of 60-100 ℃; more preferably, the temperature of the atomized gas after the second heating is controlled within the range of 60-85 ℃. The temperature of the seasoning material container 5 is preferably controlled to be in the range of 60 to 65 degrees celsius.

Wherein the heating temperature of the secondary heating element 7 is 60-100 ℃, so that the temperature of the atomized gas heated by the secondary heating element 7 is 60-100 ℃. By controlling the temperature of the heated atomizing gas to be 60-100 ℃, on one hand, the components in the seasoning material can be volatilized, and on the other hand, the phenomenon that the seasoning material generates scorched flavor and the taste is influenced due to overhigh temperature of the atomizing gas can also be avoided.

Further, as shown in fig. 1 and 5, fig. 5 is a partially enlarged schematic structural view of fig. 1. The electronic atomization device 100 includes a suction sensing component for sensing suction force, so as to determine whether the user is using the electronic atomization device 100. When the suction sensing assembly senses that the user is sucking the electronic atomization device 100, the suction sensing assembly generates a sensing signal, and the circuit board 3 further controls the atomization unit 4 to begin atomizing the aerosol-generating substrate after receiving the sensing signal.

As shown in fig. 1 and 5, the suction sensing assembly includes an airflow sensor airflow channel 81 and an airflow sensor 8. The airflow sensor airflow passage 81 communicates the airflow communication passage 9 with the airflow sensor 8, and the airflow sensor 8 is used to detect a pressure change in the airflow communication passage 9. That is, the airflow sensor airflow passage 81 has one end connected to the airflow communication passage 9 and one end leading to the airflow sensor 8. When the user draws, the airflow sensor 8 transmits a sensed signal to the control circuit 3, and the control circuit 3 activates the first heating element 41 to heat the aerosol.

Specifically, when a suction force acts on the electronic atomization device 100, the pressure in the airflow communication channel 9 changes, the airflow sensor airflow channel 81 is communicated with the airflow communication channel 9, the pressure change in the airflow communication channel 9 causes the pressure change in the airflow sensor airflow channel 81, and the airflow sensor 8 generates a sensing signal when sensing the pressure change in the airflow sensor airflow channel 81.

Optionally, the airflow sensor 8 is disposed above the atomizing unit 4 and the power supply 2, so that liquid leakage from the atomizing unit 4 can be prevented from polluting, the airflow sensor 8 is protected, and the detection accuracy of the airflow sensor 8 is improved.

Specifically, as shown in fig. 1, the power supply 2 and the atomizing unit 4 are arranged side by side to make the structure of the electronic atomizing device 100 more compact. The airflow sensor 8 is disposed above the power supply 2 to prevent the suction sensing assembly from interfering with the airflow communication channel 9.

Fig. 6 is a circuit schematic diagram 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 air flow 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.

A heating control method of an electronic atomization device comprises the following steps:

when a suction signal is received, starting a primary heating element to heat the liquid storage of the atomization unit to form atomized gas;

and judging whether a user selects a secondary heating mode, and determining whether to start a secondary heating element for heating, wherein the secondary heating element is arranged in an air flow communication channel between the seasoning material and the atomizing unit.

Specifically, please refer to fig. 7, fig. 7 is a schematic flow chart illustrating a heating control method according to an embodiment of the present invention. Another aspect of the present invention further provides a heating control method, which is applied to the electronic atomization device 100, and the heating control method in this embodiment is described in detail with reference to fig. 1 to 6. Specifically, the heating control method includes the steps of:

step S101: when a puff signal is received, a primary heating element of the nebulizing unit is activated to heat the aerosol-generating substrate to form a nebulized gas.

In particular, a puff sensing assembly disposed within the electronic nebulizing device 100 is used to sense the force of the puff of the user, the puff sensing assembly generates a puff signal when the user uses the electronic nebulizing device 100 by puffing, and the circuit board 3 receives the puff signal and controls the operation of the primary heating element 41 of the nebulizing unit 4 to heat the nebulized aerosol-generating substrate to form the nebulized aerosol.

Alternatively, in other alternative embodiments, a switch button may be further disposed on the electronic atomization device 100 to generate an activation signal by pressing the switch button, so as to control the operation of the primary heating element 41 of the atomization unit 4 to heat the atomized aerosol-generating substrate to form atomized aerosol, and the embodiment of the present invention is not limited to the activation manner of the primary heating element 41.

Step S102: and judging whether the user selects secondary heating or not.

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

Step S103: if the user selects the secondary heating, the secondary heating element is started to heat the atomized gas; wherein the secondary heating element is disposed in the air flow communication channel between the flavouring material and the atomising unit.

Specifically, if the electronic atomization device 100 determines that the user selects the secondary heating, the power supply 2 is controlled to supply power to the secondary heating element 7, so as to start the secondary heating element 7 to heat the atomization gas. The flavoring material is disposed in the air flow communication channel 9 of the electronic atomization device 100, so that the atomized air heated again by the secondary heating element 7 flows through the flavoring material and then is discharged out of the electronic atomization device 100 for the user to suck. So, the higher atomizing gas of temperature can be so that the abundant release of composition in the material of flavouring after flavouring the material, and then discharge together with the atomizing gas that aerosol generation matrix atomizing produced, supplies the user to absorb, so can promote electronic atomization device 100's taste, promotes user's use and experiences.

If the electronic atomization device 100 determines that the user does not select the secondary heating, the secondary heating element 7 is turned off.

Referring to fig. 8, fig. 8 is a schematic flowchart of step S102 in fig. 7. The step of judging whether the user selects the secondary heating specifically comprises the following steps:

step S201: and judging whether a pressing signal is received.

Wherein, the user can generate the pressing signal by pressing the pressing part 12 provided on the housing 1 to trigger the switch 6. When the pressing part is pressed, a pressing signal is generated, and the circuit board receives the pressing signal. When the pressing part is not pressed, no pressing signal is generated, and the circuit board does not generate the pressing signal.

Step S202: and judging whether the secondary heating element is started or not.

Specifically, the electronic atomization device 100 detects whether the secondary heating element 7 is heated, and if the electronic atomization device 100 detects that the secondary heating element 7 is in a heated state, the secondary heating element 7 is activated, and if the electronic atomization device 100 detects that the secondary heating element 7 is in a non-heated state, the secondary heating element 7 is not activated.

Step S203: if the pressing signal is received and the secondary heating element is not started, or if the pressing signal is not received and the secondary heating element is started, the fact that the user selects secondary heating is judged.

If, in step S101, the suction signal is received, not only the primary heating element 41 but also the secondary heating element 7 is activated at the same time, the secondary heating element 7 heats the aerosol-generating substrate formed by atomization again at the same time as the primary heating element 41 atomizes the aerosol-generating substrate. At this time, if the electronic atomization device 100 does not receive the pressing signal and determines that the secondary heating element 7 is activated, it is determined that the user selects the secondary heating, and at this time, the secondary heating element 7 continuously heats the atomization gas. If the electronic atomization device 100 receives the pressing signal and determines that the secondary heating element 7 is 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.

If the pumping signal is received in step S101, 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 does not select the 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 selects the secondary heating, and at this time, the secondary heating element 7 continuously heats the atomization gas.

Further, the step of activating the secondary heating element 7 to heat the atomizing gas comprises: the secondary heating element 7 is controlled to heat the atomizing gas again so that the temperature of the heated atomizing gas is 60-100 ℃. By controlling the temperature of the heated atomizing gas to be 60-100 ℃, on one hand, the components in the seasoning material can be volatilized, and on the other hand, the phenomenon that the seasoning material generates scorched flavor and the taste is influenced due to overhigh temperature of the atomizing gas can also be avoided.

Wherein, in one embodiment, the heating temperature of the secondary heating element 7 can be set to 60-85 ℃.

Step S302: and judging whether the user selects secondary heating or not.

Step S303: if the user selects the secondary heating, the secondary heating element is started to heat the atomized gas; wherein the secondary heating element is disposed in the air flow communication channel between the flavouring material and the atomising unit.

Steps S301 to S303 are the same as steps S101 to S103 in the above embodiment, please refer to the description in the above embodiment, and are not repeated herein.

Step S304: in response to the switch control signal, the flavoring material heating element is controlled to heat the atomized flavoring material.

Alternatively, in an embodiment, the switch control signal and the pressing signal may both be triggered by the pressing part 12. Specifically, the user can generate the switch control signal and the pressing signal by pressing the pressing portion 12 provided on the housing 1 to simultaneously trigger the switch 6. At this time, the switch 6 electrically connects the flavoring material heating element 51 with the circuit board 3, the circuit board 3 electrically connects the flavoring material heating element 51 with the power supply 2, and then the flavoring material heating element 51 is controlled to heat and atomize the flavoring material, so as to further raise the temperature of the flavoring material, and facilitate the sufficient volatilization of the components in the flavoring material.

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

Further, the step of controlling the flavouring material heating element 51 to heat the atomised flavouring material comprises: the temperature at which the flavouring material heating element 51 heats the atomised flavouring material is controlled to be 60-65 ℃.

In summary, as those skilled in the art can easily understand, the embodiment of the present invention arranges the secondary heating element 7 in the air flow communication channel 9, and the secondary heating element 7 is 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 communication channel 9, before entering the flavoring material containing portion 5, the secondary heating element 7 can re-heat the cooled atomized gas, so as to re-heat the large droplets condensed in the atomized gas to form small droplet atomized gas, and further raise the temperature of the atomized gas entering the flavoring material containing portion 5, so as to fully release the components in the flavoring material, and further discharge the atomized gas formed by atomizing the aerosol generating substrate together for the user to absorb, so as to improve the taste of the electronic atomizing device 100, and the use experience of the user is improved.
