[0053] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0055] In view of the low efficiency of installing outer cotton during the current assembly process of atomizer components, the present application provides a new atomizer component, which realizes oil conduction by ventilation inside and outside the oil storage chamber through physical structure, does not require the use of outer cotton, saves materials and improves assembly efficiency.

[0056] In one embodiment, please refer to Figures 1 to 6 The atomization assembly includes an atomization housing 1, a porous oil guide member 2 and an electric heating member 3.

[0057] The atomizer housing 1 has a housing oil passage 11, and the housing oil passage 11 is used to communicate with the oil storage chamber 4 of the atomizer. For ease of understanding, the atomizer is introduced as follows: In one embodiment, please refer to Figures 1 to 3 The atomizer comprises an atomizer shell 5, and the oil storage chamber 4 is located in the atomizer shell 5 for storing the aerosol generating oil. The atomizer further comprises a suction nozzle 6 fixed on the atomizer shell 5, and the suction nozzle 6 has a suction nozzle hole 61.

[0058] The aerosol-generating oil in the oil storage chamber 4 can enter the atomizing housing 1 through the housing oil passage 11. The atomizing housing 1 has an airflow passage 12 for airflow to pass through, and the airflow passage 12 is used to communicate with the suction nozzle 6 of the atomizer. The housing oil passage 11 can be either a housing oil passage hole 110 or a housing oil passage groove. The suction nozzle hole 61 communicates with the airflow passage 12, so that the aerosol in the airflow passage 12 can be sucked through the suction nozzle hole 61.

[0059] The porous oil guide 2 is arranged in the atomizer housing 1 , and the air flow channel 12 passes through the porous oil guide 2 for the generated aerosol to enter. When the user inhales the atomizer through the mouthpiece 6 , the aerosol can be inhaled by the user through the air flow channel 12 .

[0060] The electric heating element 3 is in contact with the porous oil-conducting element 2 to heat and atomize the aerosol-generating oil entering the porous oil-conducting element 2. When the atomizer of the present application is working, the aerosol-generating oil enters the atomizing housing 1 from the oil storage chamber 4 of the atomizer through the oil passage 11 of the housing, and then enters the porous oil-conducting element 2. After entering the porous oil-conducting element 2, it can contact the electric heating element 3, so that after the electric heating element 3 contacts the aerosol-generating oil in the porous oil-conducting element 2, the aerosol-generating oil is heated and atomized to generate an aerosol. The aerosol can enter the airflow channel 12 and be inhaled by the user. The electric heating element 3 can adopt any feasible form, such as a heating wire mesh, a plurality of parallel heating wires, a hollow columnar grid, etc.

[0061] The porous oil guide 2 and the atomizing shell 1 are surrounded by a ventilation channel 7, and the ventilation channel 7 connects the shell oil passage 11 and the airflow channel 12. Compared with the current scheme of using external cotton, the atomizing component of the present application ventilates the oil storage chamber 4 by setting a ventilation channel 7 between the porous oil guide 2 and the inner wall of the atomizing shell 1, thereby reducing the types of materials, and does not need to assemble external cotton during the assembly process, which can improve the assembly efficiency. During the manufacturing process of the atomizing component, by designing the size of the ventilation channel 7, the ventilation speed of the oil storage chamber 4 can be controlled to control the speed of the aerosol-generated oil entering the atomizing shell 1, thereby reducing the leakage of the aerosol-generated oil.

[0062] The ventilation channel 7 can be in any feasible form. For example, in one embodiment, please refer to Figures 3 to 5 , the inner wall of the atomizer housing 1 has a ventilation groove 13, the ventilation groove 13 has a ventilation notch 131, the ventilation notch 131 is opposite to the groove bottom of the ventilation groove 13, and the porous oil guide member 2 covers at least a portion of the ventilation notch 131 to enclose the ventilation channel 7. For another example, in one embodiment, an oil guide groove is processed on the porous oil guide member 2, and the inner wall of the atomizer housing 1 covers at least a portion of the notch of the oil guide groove to enclose the ventilation channel 7. For another example, in one embodiment, the inner wall of the atomizer housing 1 has a ventilation groove 13, and the porous oil guide member 2 has an oil guide groove, and the notch of the oil guide groove and the notch of the ventilation groove 13 are opposite to each other to enclose the ventilation channel 7.

[0063] Furthermore, in one embodiment, the porous oil-guiding member 2 is oil-guiding cotton, and some cotton threads of the oil-guiding cotton (not shown in the figure) extend from the ventilation groove 131 into the ventilation groove 13. In this way, the cotton threads extending into the ventilation groove 13 can prevent the aerosol-generating oil from leaking from the ventilation groove 13. In some other embodiments, the porous oil-guiding member 2 can also be microporous ceramics. In this case, the ventilation groove 13 is smaller in size, and the ventilation groove 13 is a micro-channel structure, which can lock the entering aerosol-generating oil through capillary force to prevent the aerosol-generating oil from leaking. It should be noted that when the porous oil-guiding member 2 is oil-guiding cotton, in order to reduce the leakage of the aerosol-generating oil, the ventilation groove 13 can also be set as a micro-channel structure.

[0064] Further, in one embodiment, please refer to Figures 3 to 5 , the extension direction of the ventilation groove 13 is consistent with the extension direction of the air flow channel 12, and the ventilation groove 13 extends to the end of the atomizer housing 1. In this way, the ventilation groove 13 has a simple structure and is more convenient for processing the ventilation groove 13. In some other embodiments, the ventilation groove 13 can adopt any other feasible structure, for example, the ventilation groove 13 can be a reciprocating curved groove or a spiral groove.

[0065] In one embodiment, please refer to Figure 5 and Figure 6 , a portion of the ventilation slot 131 is covered by the porous oil guide member 2, and a portion thereof is connected to the air flow channel 12. In some other embodiments, the ventilation slot 131 may be completely covered by the porous oil guide member 2.

[0066] Further, in one embodiment, please refer to Figure 3 , Figure 5 and Figure 6 In the airflow direction of the airflow channel 12, the ventilation groove 13 is located upstream of the shell oil passage 11 and extends to the end opening of the airflow channel 12. In this case, the ventilation groove 13 is more convenient to process. In some other embodiments, in the airflow direction of the airflow channel 12, the ventilation groove 13 can be located downstream of the shell oil passage 11. In this way, when in use, the ventilation groove 13 is on the upper side of the shell oil passage 11, and the aerosol-generated oil is less likely to leak.

[0067] Specifically, in one embodiment, please refer to Figure 3 , Figure 5 and Figure 6 The atomizer housing 1 is a sleeve-shaped structure, and the inner hole of the atomizer housing 1 includes a large diameter section 14, a transition section 15 and a small diameter section 16, wherein the porous oil guide member 2 is in the large diameter section 14, and the housing oil hole 110 is connected with the large diameter section 14. The ventilation groove 13 is on the hole wall of the large diameter section 14, so that the operation space is larger when processing the ventilation groove 13, which is convenient for processing the ventilation groove 13. Of course, in some other embodiments, the atomizer housing 1 can also be formed by integral die casting or integral injection molding.

[0068] In one embodiment, please refer to Figure 4 , Figure 5 and Figure 6 , the number of the ventilation groove 13 is one, and the number of the housing oil holes 110 is four. In some other embodiments, the ventilation groove 13 may also correspond to the housing oil holes 110 one by one.

[0069] In one embodiment, please refer to Figure 4 , Figure 5 and Figure 6The porous oil guide member 2 is an oil guide sleeve, the outer wall surface of the oil guide sleeve is in contact with the inner wall surface of the atomizing shell 1, and the electric heating member 3 is in contact with the inner wall surface of the oil guide sleeve.

[0070] In one embodiment, the aerosol-generating oil is tobacco oil.

[0071] In one embodiment, the assembly process of the atomizer assembly is as follows:

[0072] The side of the electric heating element 3 without pins is attached to the oil-conducting cotton, tightly wrapped around a cotton stick (auxiliary structure, not shown) and loaded into a cotton clamping fixture (auxiliary structure, not shown), and then the excess oil-conducting cotton is removed and assembled into the atomizing housing 1 through a cotton pushing fixture (auxiliary structure, not shown).

[0073] For an embodiment of an atomizer, please refer to Figures 1 to 6 The atomizer comprises an atomizer shell 5, a suction nozzle 6 arranged on the atomizer shell 5 and an atomizing assembly, and the atomizer shell 5 has an oil storage chamber 4. The structures of the atomizing assembly, the atomizer shell 5 and the suction nozzle 6 can refer to the structures introduced in any of the above embodiments, and will not be repeated here.

[0074] In an embodiment of an electronic atomization device, the electronic atomization device includes an atomizer and a power supply, and the power supply supplies power to the atomizer.
