[0051] The base 110 has a first accommodating cavity 111.
[0052] The sleeve 120 is disposed in the first accommodating cavity 111 of the base 110.
[0053] The atomizing core 130 is disposed in the sleeve 120. The atomizing core 130 includes a liquid guiding member 131 and a first heating element 132 disposed on the liquid guiding member 131. In this embodiment, the first heating element 132 is a heating wire. According to needs, the heating method of the first heating element 132 can also be other heating methods, such as resistance heating atomization, electromagnetic induction heating atomization, etc. Different heating methods can be selected according to actual needs. In this embodiment, the liquid guiding member 131 is a liquid storage cotton.
[0054] The second heating element 140 is disposed in the first accommodating cavity 111 of the base 110. The second heating element 140 is located at the bottom of the atomizing core 130. The second heating element 140 is used to receive the aerosol-forming matrix leaked from the liquid guiding member 131 and atomize the aerosol-forming matrix.
[0055] In the atomization core component 100 provided in the above embodiments, since the second heating element 140 is located at the bottom of the atomization core 130, and the second heating element 140 is used to receive the aerosol-forming matrix leaked from the liquid guide member 131 and atomize the aerosol-forming matrix. When condensation occurs during the atomization process or when the smoke flows back during smoking, or when the liquid guide member 131 has a reduced oil-locking ability due to thermal expansion and contraction, resulting in the leakage of the aerosol-forming matrix to the base 110 of the atomization device, the second heating element 140 can receive the condensed aerosol-forming matrix or the aerosol-forming matrix leaked from the liquid guide member 131 and atomize the aerosol-forming matrix, thereby avoiding the pollution problem caused by the outflow of the aerosol-forming matrix to the external environment of the atomization device.

[0058] In this embodiment, since the bottom wall 141 and the side wall 142 together form a disc shape to receive the aerosol-forming matrix leaked from the liquid guide member 131, at this time, the aerosol-forming matrix generated by the condensation of the smoke or the aerosol-forming matrix generated by the leakage of the liquid guide member 131 can be temporarily stored in the disc formed by the bottom wall 141 and the side wall 142. At the beginning of the next atomization process, the aerosol-forming matrix in the disc can be atomized again by the second heating element 140. In this embodiment, the second heating element 140 is in the shape of a disc and is disposed in the first accommodation cavity 111 of the base 110.

In this embodiment, the second accommodation cavity 112 and the third accommodation cavity 113 are provided at the bottom of the base 110.
[0066] In some embodiments, the base 110 further includes an air intake passage L1. The air intake passage L1 includes an air inlet 114 and an air outlet 115.

In this embodiment, the number of the intake ports 114 is two. One of the intake ports 114 is arranged close to the second accommodation cavity 112, and the other intake port 114 is arranged close to the third accommodation cavity 113. The two intake ports 114 are separated by the second accommodation cavity 112 and the third accommodation cavity 113. Similarly, the number of the air outlet ports 115 is also two. One of the air outlet ports 115 is arranged close to the second accommodation cavity 112, and the other air outlet port 115 is arranged close to the third accommodation cavity 113. The two air outlet ports 115 are respectively communicated with the corresponding two intake ports 114.
[0071] According to requirements, a first through hole 1111 and a second through hole 1112 are provided at the bottom of the first accommodation cavity 111.
[0072] The first through hole 1111 extends from the first accommodation cavity 111 to the second accommodation cavity 112. One of the electrodes of the first heating element 132 or the second heating element 140 passes through the first through hole 1111 to be connected with the first electrode 151.
[0073] The second through hole 1112 extends from the first accommodation cavity 111 to the third accommodation cavity 113. The other electrode of the first heating element 132 or the second heating element 140 passes through the second through hole 1112 to be connected with the second electrode 152.
[0074] By providing a first through-hole 1111 and a second through-hole 1112 at the bottom of the first accommodation cavity 111, the electrodes of the first heating element 132 or the second heating element 140 can conveniently pass through the base 110 to form an electrical connection with the first electrode 151 or the second electrode 152, thus facilitating the assembly process of the atomization core assembly 100. In fact, a first electrode lead accommodation groove 1121 is further provided in the second accommodation cavity 112, and a second electrode lead accommodation groove 1131 is further provided in the third accommodation cavity 113. When the electrode of the first heating element 132 or the second heating element 140 passes through the first through-hole 1111, its exposed part can be bent into the first electrode lead accommodation groove 1121. When the first electrode 151 is placed in the second accommodation cavity 112, the exposed part of the electrode of the first heating element 132 or the second heating element 140 can form an electrical connection with the first electrode 151. Similarly, when the other electrode of the first heating element 132 or the second heating element 140 passes through the second through-hole 1112, its exposed part can be bent into the second electrode lead accommodation groove 1131. When the second electrode 152 is placed in the third accommodation cavity 113, the exposed part of the other electrode of the first heating element 132 or the second heating element 140 can form an electrical connection with the second electrode 152.
[0075] In some embodiments, the atomization core assembly 100 further includes a seal 160. The seal 160 is disposed on the top of the base 110 and surrounds the sleeve 120.
[0076] Please also refer to Figures 8 to 11 , one embodiment of the present application further provides an atomization device 200. The atomization device 200 is used to atomize an aerosol-forming substrate to generate an aerosol for a user to inhale, so as to replace traditional cigarettes. In this embodiment, the atomization device 200 is of the POD type and is used in combination with an external battery compartment. The atomization device 200 includes a housing 210 and the atomization core assembly 100 as described in any one of the above embodiments.
[0077] The housing 210 has a liquid storage cavity 211. An aerosol-forming substrate is disposed in the liquid storage cavity 211. In this embodiment, the housing 210, the sleeve 120, and the seal 160 together form the liquid storage cavity 211. According to requirements, a convex ring 161 is provided on the outer side of the seal 160. When the atomization core assembly 100 is assembled in the housing 210, the convex ring 161 can be in close contact with the inner wall of the housing 210, thereby ensuring the sealing between the atomization core assembly 100 and the housing 210, and further preventing the aerosol-forming substrate in the liquid storage cavity 211 from leaking.
[0078] The atomizing core assembly 100 is disposed within the housing 210. The sleeve 120 is provided with liquid guiding holes 121. The aerosol forming substrate within the liquid storage cavity 211 is transferred to the atomizing core 130 through the liquid guiding holes 121. In this embodiment, an air flow channel L2 is provided inside the atomizing core 130. When the atomizing device 200 is in operation, the first heating element 132 is energized to generate heat, thereby heating and atomizing the aerosol forming substrate in the liquid guiding member 131. The atomized aerosol forming substrate is mixed with air in the air flow channel L2 and then flows out from the suction port of the atomizing device 200 for the user to inhale.
[0079] Similarly, in the atomizing device 200 provided in the above embodiments, since the second heating element 140 is located at the bottom of the atomizing core 130, and the second heating element 140 is used to receive the aerosol forming substrate leaked from the liquid guiding member 131 and atomize the aerosol forming substrate. When condensation occurs during the atomization process or when the smoke refluxes during smoking, or when the liquid guiding member 131 has a reduced oil locking ability due to thermal expansion and contraction, resulting in the leakage of the aerosol forming substrate to the base 110 of the atomizing device, the second heating element 140 can receive the condensed aerosol forming substrate or the aerosol forming substrate leaked from the liquid guiding member 131 and atomize the aerosol forming substrate, thereby avoiding the pollution problem caused by the aerosol forming substrate flowing out to the external environment of the atomizing device 200.
[0080] In some embodiments, the atomizing device 200 further includes a mouthpiece 220.
[0081] The mouthpiece 220 is disposed at the top of the housing 210. The mouthpiece 220 has a suction port 221. The suction port 221 is in communication with the air flow channel L2 in the atomizing core assembly 100.
[0082] In some embodiments, the atomizing device 200 can be activated by detecting the sucking action of the user at the mouthpiece 220. At this time, during actual use, when the user inhales at the suction port 221 of the mouthpiece 220, the air flow detection component detects the inhalation action of the user, generates an induction signal and sends it to the control component. The control component receives the induction signal sent by the air flow detection component and controls the first heating element 132 to generate heat, thereby atomizing the aerosol forming substrate in the liquid guiding member 131. At the same time, the control component also controls the second heating element 140 to generate heat to heat the condensed aerosol forming substrate or the aerosol forming substrate leaked from the liquid guiding member 131 to atomize it again.
[0083] In some embodiments, the atomizing device 200 can also be activated by a user's key operation. At this time, during actual use, the user presses the operation key to generate a control signal and send it to the control component. The control component controls the first heating element 132 to heat up according to the control signal, so as to atomize the aerosol-forming matrix in the liquid guiding member 131. At the same time, the control component also controls the second heating element 140 to heat up, so as to heat the condensed aerosol-forming matrix or the aerosol-forming matrix leaked from the liquid guiding member 131 to atomize it again.
[0084] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will be positioned "below" or "beneath" other devices or structures afterwards. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.
