Referring to fig. 1 to 4, an atomizing assembly according to an embodiment of the present invention will now be described. Embodiments of the present invention provide an aerosol generating device comprising generally an atomiser for atomising an aerosol-forming substrate to form an aerosol, and a power supply device 8 electrically connected to the atomiser. The embodiment of the utility model provides an atomizing component is applicable to above-mentioned atomizer, then when using, power supply unit 8 can provide the electric energy to the atomizing component of atomizer, and atomizing component's heat-generating body produces the heat under the electric drive effect, can heat and atomize aerosol formation substrate for aerosol formation substrate atomization forms the aerosol of tiny granule, so that supply the user to inhale.

Please refer to fig. 1 and fig. 3 in combination, an embodiment of the present invention provides an atomizing assembly including an atomizing core 1, an atomizing support 2 and a first liquid guiding member 3, wherein a first cavity 23 is formed inside the atomizing support 2, the first liquid guiding member 3 is disposed in the first cavity 23, a liquid inlet groove 24 is disposed on the atomizing support 2, the liquid inlet groove 24 is communicated with the first cavity 23, and then aerosol-forming substrate stored inside the atomizer can be guided to the first liquid guiding member 3 through the liquid inlet groove 24. The atomizing core 1 generates heat after being electrified, and heats and atomizes the aerosol forming substrate to form aerosol which can be sucked by a user. The atomizing core 1 includes a first atomizing member 11 and a second atomizing member 12, the second atomizing member 12 is disposed in parallel with the first atomizing member 11, and the first atomizing member 11 and the second atomizing member 12 have the same resistance value. In some embodiments, the resistance of the first atomizing element 11 and the resistance of the second atomizing element 12 can be, but not limited to, 1 to 1.2 Ω. In use, with the first atomizing member 11 and the second atomizing member 12 both disposed in the first cavity 23 of the atomizing support 2, the first liquid guiding member 3 can transport the adsorbed aerosol-forming substrate to the first atomizing member 11 and the second atomizing member 12, respectively, so as to continuously and uniformly provide the aerosol-forming substrate to the first atomizing member 11 and the second atomizing member 12. Because atomizing core 1 comprises first atomizing 11 and second atomizing 12 parallelly connected, then atomizing core 1's atomizing area is bigger, but its single-point calorific capacity can reduce to can not lead to atomizing core 1's generating heat too concentrated, can reduce atomizing core 1 promptly to the requirement of first drain 3 confession liquid rate, even appear in atomizing core 1 that the confession liquid is not enough or supply under the insufficient condition, also can effectively prevent the carbonization of dry combustion. It will be appreciated that, for example, in some embodiments, the atomizing core 1 of the first embodiment, in which a single third atomizing member having a resistance of 0.6 Ω is used, due to the structural limitations of the atomizer, the smaller size of the single third atomizing member results in a more concentrated heat generation area of the third atomizing member, and the atomizing core 1 is highly susceptible to dry burning and carbonization in the case of insufficient or insufficient liquid supply of the third atomizing member, especially in the case of poor flowability of the aerosol-forming substrate. In the atomizing core 1 of the second scheme, the first atomizing part 11 and the second atomizing part 12 with the resistance values of 1.2 Ω are adopted, and the first atomizing part 11 and the second atomizing part 12 are arranged in parallel, so that the final resistance value of the atomizing core 1 is 0.6 Ω. As shown in fig. 2, when the first atomizing member 11 and the second atomizing member 12 having two resistance values of 1.2 Ω are connected in parallel, the heat generating regions of the entire atomizing core 1 can be dispersed, which is equivalent to two regions having a high resistance value generating heat simultaneously, so that under the condition that the heat generating amount and the atomizing amount are matched with the flow rate of the aerosol-forming substrate, even if the atomizing core 1 has insufficient liquid supply or insufficient liquid supply, the dry burning carbonization does not occur, and the heat generating amount and the atomizing amount of the atomizing core 1 having an equivalent resistance value of 0.6 Ω are released.

Therefore, it can be seen that, in the first scheme, the temperature of the single third atomizing part is too high, the uniformity of the temperature field distribution is poor, the atomizing core is easily subjected to dry burning carbonization, and if the heating power is reduced to reduce the temperature, the atomizing power of the atomizing core and the amount of the atomized aerosol are reduced; in the second scheme, the temperature of the first atomizing part 11 and the second atomizing part 12 which are connected in parallel is relatively low, the uniformity of temperature field distribution is good, the proper atomizing temperature is ensured, dry burning carbonization is avoided, and the atomizing power of the atomizing core and the amount of the atomized aerosol are not reduced.
