[0002] As an important component in an aerosol generating device, the main function of the atomization core is to heat an aerosol generating substrate to generate an aerosol.

[0003] During the process of heating the aerosol generating substrate by the existing atomization core, condensate will form at the cold-hot intersection inside the atomization core. As the condensate accumulates, the condensate will form droplets and drip to the bottom of the atomization core and / or the aerosol generating substrate will drip to the bottom of the atomization core. Generally, ventilation holes communicating with the atmosphere are provided at the bottom of the atomization core. After the condensate and / or the aerosol generating substrate drip to the bottom of the atomization core, the liquid will leak out from the bottom of the atomization core, thus polluting the appearance of the aerosol generating device.

[0032] As used herein, the mention of "embodiments" means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0033] An embodiment of this application provides a leak-proof atomization core. Refer to Figures 1 to 7 , Figures 1 to 7 The leak-proof atomization core provided by Embodiment 1 of this application is shown as follows. The leak-proof atomization core includes a bracket 100, an aerosol generating component 200, and an electrode 300. The aerosol generating component 200 and the electrode 300 are both connected inside the bracket 100. An atomization cavity 101 is provided inside the bracket 100. The aerosol generating component 200 is used to heat the aerosol generating substrate to form aerosol in the atomization cavity 101. An air intake channel 301 is provided inside the electrode 300, and an air intake port 302 is provided on the side wall of the electrode 300. The air intake channel 301 is communicated with the atomization cavity 101 through the air intake port 302. A liquid storage tank 102 is formed by the outer wall of the electrode 300 and the bracket 100, and the liquid storage tank 102 is located below the aerosol generating component 200.

[0034] It can be understood that the working principle of the leak-proof atomization core provided by this application is as follows:

[0035] When the atomization core is working, the aerosol generating component 200 heats the aerosol generating substrate and forms aerosol in the atomization chamber 101. When the user inhales the aerosol, the gas enters the atomization chamber 101 from the intake channel 301 through the intake port 302, and takes out the aerosol in the atomization chamber 101 for the user to inhale. During the process of the aerosol generating component 200 heating the aerosol generating substrate, condensate will be formed at the aerosol generating component 200. The condensate is generally a mixture of water and the aerosol generating substrate. The condensate accumulates into large particles and forms liquid droplets at the aerosol generating component 200, or the aerosol generating substrate will drip into the liquid storage tank 102 located below the aerosol generating component 200. Under the action of suction, the liquid in the liquid storage tank 102 will be suctioned back along the outer wall of the electrode 300 and re-enter the aerosol generating component 200, as Figure 5 shown, and then the aerosol generating component 200 re-heats and atomizes the aerosol generating substrate in the liquid.

[0036] Compared with the prior art, the leak-proof atomization core provided by the present application has at least the following technical effects:

[0037] In the present application, by setting the electrode 300, the intake channel 301 in the electrode 300 is communicated with the atomizer, and the electrode 300 and the bracket 100 cooperate to form the liquid storage tank 102. While ensuring that the aerosol in the atomization chamber 101 can be discharged under the action of air flow, the condensate can be collected in the liquid storage tank 102 after dripping, avoiding the leakage of the condensate from the atomization core, and the condensate can be atomized twice to reduce the accumulation of the condensate, and at the same time avoid the waste of the aerosol generating substrate.

[0038] In this embodiment, at least two intake ports 302 are provided on the side wall of the intake channel 301, and the intake ports 302 are evenly distributed on the side wall of the intake channel 301, and the top end of the electrode 300 is sealed. Specifically, the intake end of the intake channel 301 is arranged at the bottom of the electrode 300, and the intake channel 301 is communicated with the atmosphere. When the user applies suction to the atomization core, the air in the atmosphere is inhaled from the bottom of the electrode 300 into the intake channel 301, and then enters the atomization chamber 101 through the intake port 302 (as Figure 7 shown). The intake ports 302 are evenly distributed at the same horizontal height, and the top of the electrode 300 is sealed, so that the air can only enter the atomization chamber 101 dispersedly from the evenly distributed intake ports 302, so that the air flow entering from the outside can enter the atomization chamber 101 dispersedly, mix fully with the aerosol in the atomization chamber 101, can carry away more aerosol, improve the flow rate of the aerosol, and enable the aerosol generating substrate to be fully atomized.

[0039] Refer to Figures 1 to 7, in this embodiment, under the action of external suction, the condensate can form a trickle and flow upward along the interval area formed between adjacent air inlets 302 on the electrode 300. Since the air inlets 302 are opened on the side wall of the electrode 300, the area of the side wall becomes smaller. The smaller side wall area limits the particles of the refluxing condensate, and only small particles can continue to be sucked back upward along the side wall of the electrode 300. The small-particle condensate is sucked back into the atomization chamber 101 and reaches the aerosol generating assembly 200, where it can be heated and atomized more quickly, ensuring that the sucked-back condensate can be fully heated and atomized, and preventing large particles from being directly sucked out of the atomization core into the user's mouth after being sucked back, which affects the user experience.

[0040] In this embodiment, the lowest point of the air inlet 302 is higher than the bottom surface of the bracket 100. Specifically, the plane where the lowest point of the air inlet 302 is located is higher than the plane where the bottom surface of the bracket 100 is located, so that the side wall of the electrode 300 below the air inlet 302 can enclose a liquid storage tank 102 with the bracket 100, and the condensate will not flow into the air inlet passage 301 from the air inlet 302.

[0041] In this embodiment, the electrode 300 is located directly below the atomization chamber 101, facilitating the suction of the condensate along the electrode 300 back into the atomization chamber 101 and reaching the aerosol generating assembly 200 for heating and atomization.

[0042] In this embodiment, the leak-proof atomization core further includes a first seal 400, which is arranged at the connection between the bracket 100 and the electrode 300. The first seal 400 is used to fill the connection gap between the bracket 100 and the electrode 300. Specifically, the liquid storage tank 102 is formed by enclosing the bracket 100, the first seal 400 and the electrode 300. The first seal 400 can improve the tightness of the liquid storage tank 102 and prevent the condensate stored in the liquid storage tank 102 from leaking out through the connection gap between the bracket 100 and the electrode 300.

[0043] In this embodiment, both the electrode 300 and the bracket 100 are made of conductive materials, and the first seal 400 is made of insulating materials. The electrode 300 and the bracket 100 are respectively conductive electrodes. The first seal 400 arranged at the connection between the bracket 100 and the electrode 300 also serves to separate the two conductive electrodes to avoid short circuits. The structure is simple, saving the space of each component in the atomization core and facilitating the miniaturization of the atomization core.

[0044] In this embodiment, the aerosol generating component 200 includes a liquid guiding member 210 and a heating element 220. The liquid guiding member 210 is connected to the bracket 100. The liquid guiding member 210 is used to contact the aerosol generating substrate. The heating element 220 is connected to the liquid guiding member 210. The heating element 220 is used to heat the aerosol generating substrate entering the liquid guiding member 210 to form an aerosol in the atomization chamber 101.

[0045] Specifically, the two electrode pins of the heating element 220 are respectively connected to the electrode 300 and the bracket 100.

[0046] Furthermore, in this embodiment, the liquid guiding member 210 is cylindrical. The outer side of the liquid guiding member 210 is connected to the bracket 100. The heating element 220 is connected to the inner side wall of the liquid guiding member 210. The atomization chamber 101 is located inside the liquid guiding member 210. The heating element 220 is connected to the inner side wall of the cylindrical liquid guiding member 210, enabling the heating element and the liquid guiding member 210 to have a larger contact area and increasing the atomization amount. The atomization chamber 101 is the inner cavity of the liquid guiding member 210. Airflow is discharged from the plurality of air inlets 302 at different directions below the atomization chamber 101 and is sucked upward into the atomization chamber 101. The aerosol in the atomization chamber 101 is discharged upward under the action of suction.

[0047] The liquid storage tank 102 is located below the liquid guiding member 210. The liquid storage tank 102 is an annular groove. The opening of the liquid storage tank 102 faces the liquid guiding member 210, enabling the condensate dripping from the liquid guiding member 210 to be collected in the liquid storage tank 102. The electrode 300 is cylindrical, and the air inlets 302 are circumferentially distributed, allowing airflow to enter the atomization chamber 101 from multiple directions.

[0048] In this embodiment, the leak-proof atomization core further includes a sleeve 500 and an outer wrapping member 600. The outer wrapping member 600 is connected to the outside of the bracket 100. The sleeve 500 is connected to the outside of the bracket 100. The bracket 100 is provided with a first through hole 103, and the sleeve 500 is provided with a second through hole 501. The first through hole 103 and the second through hole 501 are correspondingly arranged. The aerosol generating substrate enters the liquid guiding member 210 through the second through hole 501 and the first through hole 103 in sequence. Specifically, the outer wrapping member 600 is made of a material such as cotton or ceramic that can conduct the aerosol generating substrate. The outer wrapping member 600 is arranged between the sleeve 500 and the bracket 100 and is used to guide the aerosol generating substrate into the liquid guiding member 210.

[0049] In this embodiment, the leak-proof atomization core further includes a second sealing ring. The second sealing ring is connected to the outside of the bracket 100. When the bracket 100 is connected to the housing of the atomizer, the second sealing member 700 is used to fill the connection gap between the bracket 100 and the housing of the atomizer.

[0050] Based on the above leak-proof atomization core, an embodiment of the present application further provides an atomizer, which includes the leak-proof atomization core described in Embodiment 1.

[0051] The atomizer further includes a housing. The atomization core is connected inside the housing, and a liquid storage cavity is formed by enclosing the outside of the atomization core and the inside of the housing.

Further, the power supply component is electrically connected to the positive electrode pin and the negative electrode pin of the heating element 220 through the electrode 300 and the bracket 100 respectively.
