DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0028] The present disclosure will now be described in detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, and only illustrate the basic structure of the present disclosure in a schematic manner, so they only show the structures related to the present disclosure.

[0029] First embodiment [0030] As shown in FIG. 1 and FIG. 2, the first embodiment of the present disclosure provides an aerosol generating device. The aerosol generating device includes an atomizer 100 and a power supply device electrically connected to the atomizer 100. Specifically, the atomizer 100 includes a liquid storage member 10 and an atomizing assembly 20 received in the liquid storage member 10. The liquid storage member 10 is provided with a liquid storage cavity 11 therein. The liquid storage cavity 11 is configured to store an aerosol-forming substrate. The atomizing assembly 20 includes an atomizing member 21. The atomizing member 21 is made of a porous material, and the porous material can conduct electricity. The atomizing member 21 is electrically connected with the power supply device, so that the atomizing member 21 not only can guide liquid, but also can conduct electricity. The aerosol-forming substrate in the liquid storage cavity 11 flows to the atomizing member 21 and is absorbed by the atomizing member 21, the power supply device supplies power to the atomizing member 21, and the atomizing member 21 atomizes the aerosol-forming substrate to generate smoke for the user to inhale.

[0031] The liquid storage member 10 is substantially in the form of a hollow cylindrical structure with an opening at a bottom end thereof. A vent tube 12 is provided in the liquid storage member 10. The vent tube 12 is substantially in the form of a hollow cylindrical structure. The liquid storage member 10 is provided with a smoke outlet 13, and the smoke outlet 13 communicates with the inner cavity of the vent tube 12.

[0032] The atomizing assembly 20 also includes an atomizing base 22 arranged at one end of the liquid storage member 10 and a mounting member 23 arranged on the atomizing base 22. The atomizing base 22 is arranged at one end of the liquid storage member 10 away from the smoke outlet 13. One end of the mounting member 23 is connected with the atomizing base 22, and the other end of the mounting member 23 is connected to the vent tube 12. The cavity in the mounting member 23 forms an atomizing cavity 24. The mounting member 23 is provided with at least one liquid inlet hole 231. The liquid inlet hole 231 is in communication with the liquid storage cavity 11 and the atomizing cavity 24. The atomizing base 22 is provided with an air inlet hole 221. One end of the atomizing cavity 24 is communicated with the air inlet hole 221, and the other end of the atomizing cavity 24 is communicated with the inner cavity of the vent tube 12. The atomizing member 21 is received in the atomizing cavity 24. The aerosol-forming substrate in the liquid storage cavity 11 flows to the atomizing member 21 through the liquid inlet hole 231 to be absorbed by the atomizing member 21 and stored on the atomizing member 21.

[0033] As shown in FIG. 1 or FIG. 3, the atomizing member 21 is generally in the shape of a sheet. The atomizing member 21 is made of a porous conductive material selected from metal, metal alloy, carbon, semiconductor material or conductive ceramic, or a combination thereof The atomizing member 21 is provided with a plurality of micro pores, so that the atomizing member 21 can guide liquid and conduct electricity, [0034] The shape of the atomizing member 21 matches the amount of the aerosol-forming substrate to be atomized in different regions of the atomizing member 21. Since the amount of the aerosol-forming substrate to be atomized in different regions of the atomizing member 21 is different, the effective heating area required by different regions of the atomizing member 21 is different, that is, the shape of the atomizing member 21 is different. The atomizing member 21 includes at least two regions, and the effective heating area of one region with a large amount of the aerosol-forming substrate to be atomized is larger than the effective heating area of the other region with a small amount of the aerosol-forming substrate to be atomized. In this embodiment, one of the regions of the atomizing member 21 is the upper half of the atomizing member 21, and the other region is the lower half of the atomizing member 21. Due to the gravity effect of the aerosol-forming substrate, the aerosol-forming substrate flowing from the liquid storage cavity 11 to the atomizing member 21 will accumulate in the lower half of the atomizing member 21, so that the aerosol-forming substrate to be atomized in the lower half of the atomizing member 21 will be more. Therefore, the effective heating area of the lower half of the atomizing member 21 is larger than the effective heating area of the upper half of the atomizing member 21, the resistance of the lower half of the atomizing member 21 is greater than the resistance of the upper half of the atomizing member 21, that is, the heating power of the lower half of the atomizing member 21 is greater than the heating power of the upper half of the atomizing member 21. As shown in FIG. 3, the atomizing member 21 is trapezoidal. It can be understood that, in other embodiments not shown, since the region of the atomizing member 21 near the liquid inlet hole 231 first contacts the aerosol-forming substrate, and then the aerosol-forming substrate spreads to other regions, so that the region of the atomizing member 21 near the liquid inlet hole 231 contacts more aerosol-forming substrate. Thus, the effective heating area of the region of the atomizing member 21 near the liquid inlet hole 231 can be increased, so that the shape of the atomizing member 21 matches the amount of the aerosol-forming substrate to be atomized in different regions of the atomizing member 21.

[0035] The atomizing member 21 includes an atomizing main body 211 and two conductive parts 212 provided on the atomizing main body 211. The atomizing main body 211 is used for absorbing and storing the aerosol-forming substrate. The two conductive parts 212 are provided on opposite sides of the atomizing main body 211. One of the conductive parts 212 is electrically connected to one of the positive and negative electrodes of the power supply device, the other conductive part 212 is electrically connected to the other one of the positive and negative electrodes of the power supply device, so that the atomizing member 21 is electrically connected to the power supply device, and the power supply device can provide electrical energy to the atomizing main body 211 to heat the aerosol-forming substrate on the atomizing main body 211.

[0036] In this embodiment, the two conductive parts 212 may be formed by protruding outward from the atomizing main body 211. As shown in FIG. 3, one of the conductive parts 212 is arranged on the upper end surface of the atomizing member 21, the other conductive part 212 is arranged on the lower end surface of the atomizing member 21. It can be understood that, in other embodiments not shown, according to the structure in the atomizer 100 or the circuit design requirements in the atomizer 100, the two conductive parts 212 may be formed at other opposite sides of the atomizing main body 211. [0037] The sheet-like structure of the atomizing member 21 enables the atomizing member 21 to heat more uniformly and to atomize more sufficiently. It can be understood that the atomizing member 21 has a uniform thickness, so that the resistance per unit area of the atomizing member 21 is the same, and accordingly, the amount of the atomized aerosol-forming substrate per unit area of the atomizing member 21 is the same. Alternatively, the atomizing member 21 has an uneven thickness, so as to satisfy that the amount of the aerosol-forming substrate to be atomized in different regions of the atomizing member 21 is different. In this embodiment, the average thickness of the atomizing member 21 is 1 mm. It can be understood that, in other embodiments not shown, in order to make the liquid guide rate of the atomizing member 21 faster and the heating more uniformly, the average thickness of the atomizing main body 211 is in the range of 0.03 to 2 mm [0038] In one embodiment, the atomizing member 21 is provided with a plurality of first grooves 213 arranged at intervals. The first groove 213 is formed by extending from the peripheral side of the atomizing member 21 towards an interior of the atomizing member 21. Due to the presence of the first groove 213, the aerosol-forming substrate does not flow in the first groove 213, so that the effective heating area of the region where the groove 213 is provided in the atomizing member 21 is reduced, so as to match the amount of the aerosol-forming substrate to be atomized in this region. It can be understood that, according to the different amounts of the aerosol-forming substrate to be atomized in different regions of the atomizing member 21, the plurality of first grooves 213 can be arranged on one side of the atomizing member 21; alternatively, as shown in FIG. 3, the plurality of first grooves 213 are arranged on opposite sides of the atomizing member 21; alternatively, in another embodiment, as shown in FIG. 4, the plurality of first grooves 213 are arranged obliquely. It can be understood that, the groove wall area of the first groove 213 (i.e., the depth or width of the first groove 213) matches the amount of the aerosol-forming substrate to be atomized in the region where the first groove 213 is provided in the atomizing member 21. That is, when the amount of the aerosol-forming substrate to be atomized in the region where the first groove 213 is provided is large, the groove wall area of the first groove 213 is reduced, thereby reducing the effective heating area of this region and reducing the amount of the aerosol-forming substrate being atomized; when the amount of the aerosol-forming substrate to be atomized in the region where the first groove 213 is provided is small, the groove wall area of the first groove 213 is increased, thereby increasing the effective heating area of this region and increasing the amount of the aerosol-forming substrate being atomized.

[0039] In another embodiment, as shown in FIG. 4, the atomizing member 21 is further recessed to be provided with a second groove 214. The groove wall area of the second groove 214 is larger than the groove wall area of the first groove 213. That is, the depth or width of the second groove 214 is greater than the depth or width of the first groove 213. Due to the presence of the second groove 214, the aerosol-forming substrate does not flow in the second groove 214, so that the effective heating area of the region where the second groove 214 is provided in the atomizing member 21 is reduced, to enable the effective heating area of the region where the second groove 214 is provided in the atomizing member 21 to match the amount of the aerosol-forming substrate to be atomized in this region. As shown in FIG. 4, due to the action of gravity, the aerosol-forming substrate flows in the atomizing member 21 from the direction close to the smoke outlet 13 to the direction away from the smoke outlet 13, so that the amount of the aerosol-forming substrate to be atomized in the region of the atomizing member 21 close to the smoke outlet 13 is smaller than the amount of the aerosol-forming substrate to be atomized in the region of the atomizing member 21 away from the smoke outlet 13. Therefore, the second groove 214 is arranged close to the smoke outlet 13, so that the effective heating area of the region close to the smoke outlet 13 on the atomizing member 21 is reduced, so as to avoid that the amount of the aerosol-forming substrate to be atomized in local area of the atomizing member 21 is insufficient to occur dry burning.

[0040] In one embodiment, as shown in FIG. 3, the atomizing member 21 is provided with at least one through hole 215. The aerosol-forming substrate does not flow in the through hole 215. The presence of the through hole 215 reduces the effective heating area of the region where the through hole 215 is provided in the atomizing member 21, so that the effective heating area of the region where the through hole 215 is provided in the atomizing member 21 matches the amount of the aerosol-forming substrate to be atomized in this region.

[0041] Furthermore, a protrusion corresponding to the through hole 215 is protruded on the cavity wall of the atomizing cavity 24. When the atomizing member 21 is received in the atomizing cavity 24, the protrusion can be inserted into the through hole 215, which is convenient for fixing the atomizing member 21 and preventing the atomizing member 21 from loosening or bending. Or, the protrusion corresponds to the first groove 213, and when the atomizing member 21 is received in the atomizing cavity 24, the protrusion can be inserted into the first groove 213 and can also play a role of fixing the atomizing member 21.

[0042] It can be understood that in other embodiments not shown, the shape of the atomizing member 21 can also be other irregular polygons, as long as the shape of the atomizing member 21 matches the amount of the aerosol-forming substrate to be atomized in different regions of the atomizing member 21. In other embodiments not shown, other types of fixing structures may also be provided on the cavity wall of the atomizing cavity 24, as long as the atomizing member 21 is stably and flatly fixed in the atomizing cavity 24.

[0043] When the aerosol generating device of this embodiment is in use, the aerosol-forming substrate in the liquid storage cavity 11 flows to the atomizing member 21 through the liquid inlet hole 231, the atomizing member 21 heats the aerosol-forming substrate under the electric driving action of the power supply device to form smoke and emits it into the atomizing cavity 24, at the same time, the outside air enters the atomizing cavity 24 through the air inlet hole 221 and mixes with the smoke to form a mixed gas. When the user inhales, the mixed gas enters the user's mouth after passing through the inner cavity of the vent tube 12 and the smoke outlet 13.

[0044] In the atomizing member 21 provided in this embodiment, the atomizing member 21 is made of a porous liquid guide material, and the atomizing member 21 can conduct electricity, so that the atomizing member 21 has both liquid guide function and electricity conducting function, so as to avoid the problem of dry burning or oil frying due to the poor cooperation between the liquid guide member and the heating member in the prior art. Moreover, the shape of the atomizing member 21 matches the amount of the aerosol-forming substrate to be atomized in different regions of the atomizing member 21, that is, the effective heating area of the different regions of the atomizing member 21 matches the amount of the aerosol-forming substrate to be atomized in the different regions of the atomizing member 21. The atomizing is more sufficient, thereby avoiding dry burning or oil frying, and the user experience is good.
