Referring to fig. 1 to 8, a preheating module 1 according to an embodiment of the present utility model will be described.

When the aerosol generating device is used, the power supply device 20 can provide electric energy for the atomizer 10 and the preheating component 1, and the heat generated after the preheating component 1 is electrified can preheat the atomized liquid with higher viscosity and easy solidification, so that the viscosity of the atomized liquid with higher viscosity and easy solidification is reduced to enhance the fluidity, the liquid guiding rate of the atomized liquid with higher viscosity and easy solidification is improved, the preheated atomized liquid can be quickly transmitted to the atomizing core 9 of the atomizer 10, and the atomized liquid stored in the atomizer 10 is atomized to form aerosol which can be sucked by a user under the action of electric driving by the atomizing core 9.

Referring to fig. 1, 2 and 3 in combination, a preheating assembly 1 according to an embodiment of the present utility model includes a heating element 11, a heat conducting member 12 and a controller 13, wherein the heating element 11 may be, but is not limited to, a resistance wire or a heating film made of nichrome. The heating element 11 generates heat after being electrified, so that atomized liquid which has higher viscosity and is easy to solidify in the liquid storage cavity 60 of the atomizer 10 can be heated. The heat conducting piece 12 is used for conducting the generated heat on the heating element 11 in a dispersing way, so that the situation that the temperature is too high on the heating element 11 is avoided, and further the atomized liquid which is higher in viscosity and easy to solidify in the liquid storage cavity 60 can be heated uniformly, and the viscosity is reduced. The heating element 11 is bonded to the heat conducting member 12, and the fixing manner of the heating element 11 to the heat conducting member 12 may be, but not limited to, embedding the heating element 11 on the heat conducting member 12, welding the heating element 11 on the heat conducting member 12, or sintering the heating element 11 on the heat conducting member 12. The controller 13 is electrically connected to the heating element 11, and the controller 13 is used for controlling the heating power and/or the heating time of the heating element 11. In the process of sucking and using the aerosol generating device by a user, the user firstly preheats the atomizing liquid with higher viscosity and easy solidification by the heat generated after the preheating component 1 is electrified, so that the viscosity of the atomizing liquid with higher viscosity and easy solidification is reduced, the fluidity is enhanced, the liquid guiding rate of the atomizing liquid with higher viscosity and easy solidification is improved, and the preheated atomizing liquid can be quickly transmitted to the atomizing core 9 of the atomizer 10. After the preheated atomized liquid can be quickly transferred to the atomizing core 9 of the atomizer 10, a user can suck and use the aerosol generating device, and the controller 13 can control the heating element 11 to stop preheating the atomized liquid in the atomizer 10 when the controller 13 senses the sucking airflow formed by sucking of the user. In the process of sucking the aerosol generating device by a user, when the user stops sucking the aerosol generating device, the controller 13 does not sense the sucking air flow, the controller 13 controls the heating element 11 to preheat the atomized liquid in the atomizer 10, so that the heating element 11 can preheat the atomized liquid in the atomizer 10 within the interval time between two times of sucking by the user, the preheated atomized liquid is effectively prevented from being lower in viscosity or solidified again to cause poorer flowability, the user can suck the aerosol without waiting for longer time when sucking next time, and the reduction of the aerosol generating amount due to poorer flowability and slower liquid guiding rate of the atomized liquid due to lower viscosity is effectively avoided, so that the sucking taste and the using experience of the user are improved.

Compared with the prior art, when the aerosol amount generated by the suction of the aerosol generating device is reduced due to the fact that the viscosity of the atomized liquid in the liquid storage cavity 60 of the atomizer 10 is high and solidification is easy, the atomized liquid in the liquid storage cavity 60 can be uniformly preheated by utilizing the heat generated by the preheating component 1, so that the viscosity of the preheated atomized liquid is reduced, the fluidity is enhanced, the liquid guide rate of the atomized liquid is improved, the aerosol amount generated by the single-port suction of the aerosol generating device is improved, a user can quickly suck enough aerosol without waiting for a long time, and the suction taste of the user is improved. In addition, at the moment when the user stops sucking the aerosol generating device, the controller 13 can control the heating element 11 to preheat the atomized liquid in the atomizer 10, so that viscosity reduction or solidification of the preheated atomized liquid is effectively prevented from happening again within the interval time between two times of sucking of the user, the user can quickly suck sufficient aerosol without waiting for a long time again when sucking next time, and the sucking use experience of the user is improved.

When the user stops sucking the aerosol generating device, the controller 13 does not sense the suction airflow, the controller 13 controls the heating element 11 to preheat the atomized liquid in the atomizer 10, so that the heating element 11 can still preheat the atomized liquid in the atomizer 10 within the interval time between two times of user suction, the preheated atomized liquid is effectively prevented from being lower in viscosity or solidified again to cause poorer fluidity, and the user can quickly suck sufficient aerosol without waiting again in the next suction, so that the suction taste and the use experience of the user are improved. It should be noted that, the airflow sensor 131 may be, but is not limited to, a microphone disposed at an air inlet of the atomizer 10, and when the microphone senses the suction airflow, the microphone may automatically start the atomizing core 9 of the atomizer 10 to heat and atomize the atomized liquid.

In addition, the heat conducting member 12 can also serve as a bearing member for assisting in detachably mounting the atomizer 10, facilitating the disassembly and replacement of the atomizer 10.

Referring to fig. 1, 10 and 12 in combination, in other embodiments, the preheating assembly 1 includes a heating element 11 for generating heat when energized and a controller 13 for controlling the operation of the heating element 11, the controller 13 being electrically connected to the heating element 11. After the preheating component 1 preheats the atomized liquid in the liquid storage cavity 60 of the atomizer 10, when the airflow sensor 131 senses the suction airflow, the controller 13 controls the heating element 11 to stop preheating the atomized liquid in the atomizer 10, so that electric energy can be saved and the power supply time of the power supply device 20 can be prolonged. When the user stops sucking the aerosol generating device, the controller 13 does not sense the suction airflow, the controller 13 controls the heating element 11 to preheat the atomized liquid in the atomizer 10, so that the heating element 11 can still preheat the atomized liquid in the atomizer 10 within the interval time between two times of user suction, the preheated atomized liquid is effectively prevented from being lower in viscosity or solidified again to cause poorer fluidity, and the user can quickly suck sufficient aerosol without waiting again in the next suction, so that the suction taste and the use experience of the user are improved.

Referring to fig. 13 and 14 in combination, an embodiment of the present utility model further provides an aerosol-generating device comprising a nebulizer 10 and a power supply device 20 according to any of the embodiments described above. Since the aerosol-generating device has all the technical features of the power supply device 20 provided in any of the above embodiments, it has the same technical effects as the power supply device 20 described above.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
