Description

Atomizer core, atomizer, electronic cigarette and assembly method Technical Field

[0001] The present disclosure relates to the field of atomization technology, and in particular to an atomizer core, an atomizer, an electronic cigarette including the atomizer core, and an assembling method for the atomizer core. Background Art

[0002] An electronic cigarette (also known as an "electronic cigarette") or smoking device is an electronic delivery system that generates an aerosol from an atomized substrate for inhalation by the user. The atomized substrate can be a liquid (e.g., a smoke liquid) or a solid or gel (e.g., a smoke paste).

[0003] Typically, a traditional e-cigarette consists of a cartridge containing an atomized substance and a power supply. The cartridge also includes a heating or vaporization device, such as an atomizer containing an atomizer core. The power supply supplies power to the atomizer core, transforming the atomized substance in the cartridge into an aerosol for the user to inhale. In many e-cigarettes, the user's inhalation activates the atomizer core, vaporizing the liquid atomized substance in the cartridge. The user then inhales the resulting aerosol through the mouthpiece.

[0004] The atomizer core is a key component in e-cigarettes, directly affecting the aerosol produced by heating and atomization, thereby affecting the user experience. Existing atomizer cores have problems such as high assembly difficulty and multiple and complex processes.

[0005] Summary of the Invention

[0006] According to a first aspect of the present disclosure, an atomizing core is provided for atomizing an atomizing substrate to form an aerosol, and comprises: an atomizing core shell, the atomizing core shell defining an air flow inlet, an air flow outlet, a accommodating space between the air flow inlet and the air flow outlet, and at least one atomizing substrate inlet, the at least one atomizing substrate inlet leading to the accommodating space; an atomizing seat, the atomizing seat being arranged in the accommodating space, and defining an atomizing channel for communicating with the air flow inlet and the air flow outlet, and at least one opening, the at least one opening being used to communicate at least one atomizing substrate inlet with the atomizing channel; and at least one heating plate, the at least one heating plate being arranged in the atomizing seat, and respectively at least partially opposite to one or more of the at least one opening or respectively located in a corresponding one of the at least one opening.

[0007] According to another aspect of the present disclosure, an atomizer is provided, comprising the atomizer core and a housing. The atomizer core is disposed in the housing, and a storage cavity for storing atomized substrate is formed between the housing and the atomizer core.

[0008] According to another aspect of the present disclosure, an electronic cigarette is provided, comprising the above-mentioned atomizer and a power supply assembly for supplying power to the atomizer.

[0009] According to yet another aspect of the present disclosure, a method for assembling an atomizer core of the present disclosure is provided, wherein the atomizer core further includes an electrode and an atomizing matrix absorption material, and the atomizer seat defines a limiting structure for inserting the electrode. The assembly method comprises: inserting the electrode into the limiting structure of the atomizer seat; installing at least one heating plate and the atomizing matrix absorption material to the atomizer seat; inserting the installed atomizer seat into the accommodating space of the atomizer core housing through the air flow inlet; and closing the space between the electrode, the atomizer seat and the atomizer core housing at the air flow inlet.

[0010] According to one or more embodiments of the present disclosure, the present disclosure provides an atomizer core. By modularly arranging the various components in the atomizer core, the degree of integration of the atomizer core can be improved, so that the atomizer core can meet the requirements of standardization and modular assembly, thereby improving production efficiency and product stability.

DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0045] It should be noted that all directional indications in the embodiments of the present disclosure (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0046] In this disclosure, unless otherwise expressly specified or limited, the terms "connected" and "fixed" should be understood broadly. For example, they may refer to direct connection or indirect connection through an intermediate medium, internal communication between two elements, or interaction between two elements, unless otherwise expressly specified. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0047] As used herein, "communication" refers to fluid communication, i.e., fluid (including liquid and / or gas) can flow from one component to another. Furthermore, as used herein, communication between two components can mean direct communication between the two components, e.g., at least partial alignment of two holes, or communication through an intermediary.

[0048] In the present disclosure, unless otherwise indicated, all numbers used in the specification and claims to represent component parameters, technical effects, etc. should be understood as being modified by the term "about" or "approximately" in any case. Therefore, unless otherwise indicated, the numerical parameters listed in the following specification and the appended claims are approximate values. For those skilled in the art, it can vary according to the desired properties and effects sought to be obtained through the present disclosure, and each numerical parameter should be interpreted according to the number of significant digits and conventional rounding methods or in a manner understood by those skilled in the art.

[0049] In this disclosure, the terms used in describing the various examples are for the purpose of describing the specific examples only and are not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the element may be one or more. In addition, the term "and / or" used in this disclosure encompasses any and all possible combinations of the listed items.

[0050] "Aerosolizable substrate" refers to a mixture or auxiliary substance that can be fully or partially aerosolized into an aerosol by an electronic device or similar device. The aerosolizable substrate can include liquid media such as e-cigarette liquid, medical medications, and skin care lotions. By aerosolizing these media, an aerosol can be delivered to the user for inhalation or absorption.

[0051] "Aerosol" refers to a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium.

[0052] A "nebulizer" is a device that converts a stored atomizable matrix, i.e., atomized matrix, into an aerosol by heating or ultrasound. The atomizer core is one of the main components of a nebulizer.

[0053] In the related art, taking electronic cigarettes as an example, the atomization core usually includes two types: cotton heating core and ceramic heating core. Among them, the cotton heating core mainly wraps the heating wire around the outer periphery of cotton, or the heating wire is covered with cotton, and the ceramic heating core embeds the heating wire into the inner wall of a hollow porous ceramic. The cotton in the cotton heating core and the ceramic in the ceramic heating core are used to absorb tobacco oil and transfer it to the heating wire, which is heated by the heating wire tobacco oil and then atomized. In the related art, the pores in cotton and ceramic are irregular, resulting in individual differences in oil locking and oil conduction, and the taste consistency of the smoke produced by heating and atomization is poor. In addition, the assembly of cotton heating cores or ceramic heating cores is difficult. For example, cotton heating cores need to be manually plugged with cotton, and the assembly process of ceramic heating cores is numerous and complicated (especially the assembly and welding of the heating wire are very complicated). This leads to problems such as low production efficiency, high scrap rate, and large individual differences in the heating cores in the related art, and it is unable to meet the requirements of standardized and modular assembly.

[0054] In view of this, the present disclosure proposes a highly integrated atomizer core. By modularly arranging the various components in the atomizer core, the degree of integration of the atomizer core can be improved, so that the atomizer core can meet the requirements of standardization and modular assembly, thereby improving production efficiency and product stability. Compared with the cotton heating core (which requires manual cotton plugging) or ceramic heating core (which has many and complicated processes) in the related art, the various components in the atomizer core of the present disclosure can be standardized and modularized, and the assembly of the various components can be completed automatically, thereby improving product production efficiency and stability.

[0055] The atomizing core according to the present disclosure can be used in electronic cigarettes. In the scope of the present disclosure, "electronic cigarette" refers to a system that generates an aerosol by atomizing a matrix, such as smoke liquid (specifically smoke oil, etc.) for people to inhale, suck, chew or nasally inhale, etc. In some examples, the electronic cigarette may include a storage chamber for storing the atomizing matrix and an atomizing core for adsorbing and atomizing the atomizing matrix to form an aerosol. Among them, the atomizing matrix can be in liquid form (for example, smoke liquid) or solid or gel form (for example, smoke paste), etc. It should be understood here that the atomizing core of the present disclosure can also be used for other equipment that requires atomization of the atomizing matrix, such as medical atomizers, skin care instruments, aromatherapy devices, etc.

[0056] The atomizer core of the present disclosure will be described in detail below with reference to FIG. 1 to FIG. 28 .

[0057] According to one or more embodiments of the present disclosure, the atomizing core is used to atomize the atomizing matrix to form an aerosol, and the atomizing core includes: an atomizing core shell, the atomizing core shell defines an air flow inlet, an air flow outlet, a accommodating space between the air flow inlet and the air flow outlet, and at least one atomizing matrix inlet, and the at least one atomizing matrix inlet leads to the accommodating space; an atomizing seat, the atomizing seat is arranged in the accommodating space and defines an atomizing channel for communicating with the air flow inlet and the air flow outlet, and at least one opening, and the at least one opening is used to connect at least one atomizing matrix inlet and the atomizing channel; and at least one heating plate, the at least one heating plate is arranged in the atomizing channel, and is respectively at least partially opposite to one or more openings of the at least one opening.

[0058] Figures 1 and 2 show stereoscopic views of the atomizer core at different angles according to some embodiments of the present disclosure; Figure 3 shows an exploded view of the atomizer core of Figure 1; Figure 4 shows a cross-sectional view of the atomizer core in Figure 1, and its cutting direction passes through the atomizer matrix inlet located in the middle among the three atomizer matrix inlets in Figure 1; Figures 5 and 6 show another cross-sectional view of the atomizer core in Figure 1, and its cutting direction is orthogonal to the cutting direction of the cross-sectional view of Figure 4; Figures 7 and 8 show the atomizer seat in the atomizer core of Figure 1 in a stereoscopic view and a cross-sectional view, respectively.

[0059] As shown in FIG. 1 to FIG. 4 , the atomizer core 1000 includes an atomizer core housing 1100 , an atomizer seat 1200 and a heating plate 1300 .

[0060] The atomizer core housing 1100 defines an air flow inlet 1110, an air flow outlet 1120, a receiving space 1130 between the air flow inlet 1110 and the air flow outlet 1120, and a plurality of atomizer substrate inlets 1140 that pass into the receiving space 1130. As shown in FIG1 , the atomizer substrate inlet 1140 is formed in the atomizer core housing wall and passes through the atomizer core housing wall, thereby connecting the space outside the atomizer core housing and the receiving space 1130, so that the atomizer substrate located outside the atomizer core housing 1100 can enter the interior of the atomizer core housing 1100. In FIG1 , three atomizer substrate inlets 1140 are shown. It should be understood that other numbers of atomizer substrate inlets 1140 may also be provided.

[0061] Atomizer seat 1200 is arranged in accommodating space 1130, and defines the atomizing channel 1210 for being communicated with air flow inlet 1110 and air flow outlet 1120 and the opening 1220 for being communicated with atomizing matrix inlet 1140 and atomizing channel 1210. As shown in Figure 4, the cavity roughly in the center of atomizer seat 1200 forms atomizing channel 1210. When atomizer seat 1200 is installed in the accommodating space 1130 of atomizer core housing 1100, one end of atomizing channel 1210 is communicated with the air flow inlet 1110 of atomizer core housing 1100, and the other end is communicated with air flow outlet 1120. In addition, as shown in Figure 4, opening 1220 is formed in the side wall of atomizer seat 1200 and runs through the side wall, and opening 1220 is opposite to a plurality of atomizing matrix inlets 1140 and passes into atomizing channel 1210. Thus, the atomizing substrate outside the atomizing core housing 1100 can enter the atomizing channel 1210 through the multiple atomizing substrate inlets 1140 and the opening 1220 .

[0062] The heating plate 1300 is disposed within the atomizing seat 1200. Specifically, the heating plate 1300 is disposed within the atomizing channel 1210, and the heating plate 1300 is at least partially opposite the opening 1220, so that the atomized substrate entering through the atomized substrate inlet 1140 and the opening 1220 can reach the heating plate 1300, and is heated by the heating plate to be atomized to form an aerosol. Alternatively, the heating plate may also be located within the opening (described in detail below with reference to Figures 30 to 36).

[0063] In the above embodiment, as shown in Figure 4, when the user inhales at the airflow outlet 1120, the airflow can reach the airflow outlet 1120 from the airflow inlet 1110 via the atomization channel 1210 in the atomization seat 1200, thereby forming an airflow path. A part of the airflow path (i.e., the atomization channel 1210) forms an atomization chamber. Among them, one side of the heating plate 1300 is communicated with the atomization matrix inlet 1140 via an opening 1220, and the other side is communicated with the air fluid in the atomization channel 1210. The atomization matrix located outside the atomization core housing penetrates into the heating plate 1300 through the atomization matrix inlet 1140 and the opening 1220. In the example where the heating plate 1300 is a heating plate with micropores, it can continue to penetrate into the inside of the heating plate 1300, evaporate to form steam after heating and atomizing by the heating plate 1300. Steam is entrained in the air flowing through the atomization channel 1210 to form an aerosol for the user to inhale.

[0064] The above embodiment provides a simple and compact atomizer core 1000, which improves the integration level of the atomizer core 1000. The atomizer core housing, atomizer seat, and heater plate of the atomizer core 1000 can be designed as standardized or modular components, thereby achieving standardized or modular assembly requirements for the atomizer core 1000, thereby improving production efficiency and product stability.

[0065] The atomizer core housing 1100 is a hollow structure for providing an installation space for the atomizer seat 1200 and forming an air flow path for air to flow through inside it. The atomizer core housing 1100 can be made of a hard material such as metal, such as steel, so as to protect the components therein and separate the storage chamber from the atomization channel 1210. The atomizer core housing 1100 can be set to any shape, for example, cylindrical (as shown in Figures 22 and 23), or elliptical cylindrical (as shown in Figures 1 to 3), etc., and the present disclosure is not limited thereto. As shown in Figures 1 to 3, the atomizer core housing 1100 may include a accommodating portion (i.e., a portion including the accommodating space 1130) for accommodating the atomizer seat 1200 and a mouth for providing an air flow outlet 1120. Among them, the accommodating portion can be set to a cylindrical or elliptical cylindrical shape, etc., to match the shape of the atomizer seat 1200 accommodated. The mouth can be set to a cylindrical shape with a cross-sectional area smaller than that of the accommodating portion so that the user can inhale.

[0066] In some embodiments, the atomizing substrate inlet 1140 provided on the atomizing core housing 1100 for accessing the accommodating space 1130 can be configured as one or more windows, or one or more holes, or a combination of the two, etc., and the present disclosure is not limited thereto. The number and size of the atomizing substrate inlet can be set as needed, for example, according to a predetermined atomizing substrate flow rate, or, for example, can be set to be less than or equal to the size of the heating plate, etc.

[0067] The shape and size of the air flow inlet 1110 provided on the atomizer core housing 1100 can be set so that the atomizer seat 1200 can be arranged in the accommodating space 1130 through the air flow inlet 1110. Thus, it is convenient for the atomizer seat 1200 to enter from the air flow inlet 1110 and be installed in the accommodating space 1130, and it is particularly convenient to automatically install the atomizer seat 1200 in the accommodating space 1130 by an automated installation device. Specifically, for example, the size of the air flow inlet 1110 can be set to be slightly larger than the size of the cross section of the atomizer seat 1200, and / or the shape of the air flow inlet 1110 can be matched with the shape of the cross section of the atomizer seat 1200. Similarly, in some examples, the size of the accommodating space 1130 can also be set to be slightly larger than the size of the atomizer seat 1200, so that the atomizer seat 1200 can be inserted into the accommodating space 1130.

[0068] The atomizer seat 1200 is used to provide an installation space for the heating plate 1300 and to provide an atomization channel 1210 for air, steam and aerosol to flow through. The atomizer seat 1200 can be entirely embedded in the accommodating space 1130 or partially embedded in the accommodating space 1130. For ease of installation, the atomizer seat 1200 can be made of a flexible material such as plastic. The atomizer seat 1200 can be set to any shape, for example, cylindrical (for example, as shown in Figures 22 and 23), or elliptical cylindrical (for example, as shown in Figures 1 to 3), etc., and the present disclosure is not limited thereto.

[0069] As shown in Figures 4 to 7, the atomization channel 1210 in the atomizer seat 1200 can be set as at least one through hole or through groove, and its extension direction L can be consistent with the extension direction of the air flow path of the atomizer core housing 1100 so as to connect the air flow inlet 1110 and the air flow outlet 1120.

[0070] As shown in Figure 7, the opening 1220 on the atomizing seat 1200 can be set to one or more windows, or one or more holes, or a combination of the two, etc., and the present disclosure is not limited thereto. In the embodiments shown in Figures 1 to 7, the heating plate 1300 is inserted into the atomizing channel 1210 from one end of the atomizing channel 1210 for communicating with the airflow outlet 1120, that is, from the top in Figure 7. Referring to Figure 4, a step is provided on the inner wall of the atomizing seat 1200, and the heating plate 1300 is inserted into the atomizing channel and positioned at the step. Further, with reference to Figure 5, guide rails extending along the longitudinal direction of the atomizing seat 1200 can be provided on both sides of the step, and the heating plate 1300 can be inserted into the guide rails and moved along the guide rails to the step. Thus, it is convenient for the heating plate 1300 to be automatically installed in the atomizing channel 1210 by an automatic installation device. In some embodiments, as shown in Figures 1 to 7, the size of the opening 1220 is smaller than the size of the heating plate to prevent the heating plate 1300 from falling out of the opening 1220. In some other embodiments, the shape and size of the opening 1220 can be set so that the heating plate 1300 can be placed in the atomization channel 1210 through the opening 1220. Specifically, for example, the size of the opening 1220 can be set to be slightly larger than the size of the heating plate 1300, or the size of the opening 1220 can be set to be slightly smaller than the size of the heating plate 1300 and the heating plate 1300 can pass through, for example, slightly tilted, and / or the shape of the opening 1220 can be set to match the shape of the heating plate 1300.

[0071] As shown in Figures 4 and 7 , a protrusion 1230 is provided on the peripheral side surface of the atomizer seat 1200. When the atomizer seat is installed in the atomizer core housing 1100, when viewed along the longitudinal extension direction of the atomizer core, the protrusion 1230 is located between the opening 1220 and the airflow outlet 1120 and abuts against the inner wall of the atomizer core housing 1100, thereby substantially separating the space formed by the inner wall of the atomizer core housing 1100 and the peripheral side wall of the atomizer seat 1200 from the airflow outlet 1120. In the case where the size of the atomizer seat 1200 is slightly smaller than the accommodating space 1130, there is a small gap between the two after the atomizer seat 1200 is inserted into the accommodating space 1130. The protrusion 1230 provided on the side surface of the atomizer seat 1200 can be well abutted against the inner wall of the atomizer core housing 1100, so that the atomizer seat 1200 and the atomizer core housing 1100 are matched more closely to prevent leakage, such as preventing the liquid entering from the atomization matrix inlet 1140 from flowing out from the air flow outlet 1120. In some examples, the protrusion 1230 can surround the entire periphery of the atomizer seat 1200. In other examples, the protrusion 1230 can be only provided on one or two sides of the atomizer seat 1200. For example, as shown in Figure 7, two protrusions 1230 are respectively provided on the relatively flat front and rear sides of the atomizer seat 1200, and the cambered surfaces on the left and right sides of the atomizer seat 1200 may not be provided with protrusions 1230 due to the presence of manufacturing errors. For an oily atomized matrix, even if the protrusion 1230 is only provided around a portion of the periphery of the atomizing seat 1200 , the surface tension of the oil itself can effectively prevent the oil from leaking.

[0072] As shown in Figure 4, the heating plate 1300 provided in the atomizing channel 1210 of the atomizing seat 1200 can be set to be parallel to the extension direction L of the atomizing channel 1210. At this time, the area of ​​the air entering the atomizing channel 1210 through the heating plate 1300 is small. Alternatively, the heating plate can also be set to form a certain angle with the extension direction L of the atomizing channel, for example, at an angle of about 15 degrees (as shown in Figure 15), thereby increasing the area of ​​the heating plate 1300 passed by the air entering the atomizing channel 1210. By changing the angle between the heating plate and the extension direction of the atomizing channel, the area of ​​the heating plate 1300 passed by the air entering the atomizing channel can be changed, thereby changing the distribution characteristics of the aerosol formed. For the case of using tobacco oil as the atomizing matrix, the taste of the aerosol can be changed.

[0073] Electrode contacts are provided on the surface of the heating plate 1300. These contacts can be located on a second surface of the heating plate 1300, facing away from the outlet 1220, to prevent contact between the contacts and e-liquid, and to facilitate the electrode 1500 extending from the atomization channel 1210 into the atomizer seat 1200 and contacting the electrode contacts. This further enhances the ease of assembly of the atomizer core 1000.

[0074] The heating plate 1300 can be a sheet structure with multiple micropores, which are used to absorb the atomized substrate through capillary action. This not only controls or increases the amount of atomized substrate, such as tobacco oil, absorbed, but also ensures more uniform oil delivery, resulting in a softer aerosol with a more consistent taste. Furthermore, when the atomized substrate supplied to the heating plate 1300 is depleted, the atomized substrate stored in the micropores of the heating plate 1300 prevents the heating plate from drying out and the generation of a burnt odor. In some examples, the multiple micropores on the heating plate 1300 can be formed by laser or chemical etching to ensure uniformity, thereby further increasing the amount of atomized substrate, such as tobacco oil, absorbed. In some examples, the pore size of the multiple micropores can be micrometers. This can utilize the tension of the atomized substrate, such as tobacco oil, to prevent it from passing through the heating plate 1300 and entering the atomization channel, thereby reducing the risk of leakage. In some examples, a metal coating for heating the atomized substrate is provided on one side of the sheet structure of the heating plate 1300. In some examples, the heating plate 1300 can be made of glass, ceramic, mica, or the like.

[0075] As shown in FIG4 , the first surface of the heating plate 1300 facing the opening 1220 rests against the inner wall of the atomizer base 1200, and this first surface is sealed to the inner wall of the atomizer base 1200, for example, by a colloid. This prevents tobacco liquid entering the atomization matrix inlet 1140 and the opening 1220 from bypassing the heating plate 1300 and entering the atomization channel 1210, thereby reducing the risk of leakage. Alternatively, the heating plate 1300 may not rest against the inner wall of the atomizer base 1200, with a seal between the two being provided.

[0076] In order to further reduce the risk of leakage, the atomizer core 1000 may also include an atomizing matrix absorption material 1400. For the smoke oil, oil-conducting cotton can be used as the atomizing matrix absorption material. The atomizing matrix absorption material 1400 is embedded in the opening 1220 and is located between the atomizing matrix inlet 1140 and the heating plate 1300. The first side of the atomizing matrix absorption material 1400 covers the atomizing matrix inlet 1140 opposite to the atomizing matrix absorption material from the inside of the atomizing core housing, and the second side opposite to the first side is abutted against the heating plate opposite to the atomizing matrix absorption material, specifically against the first surface of the heating plate 1300 facing the opening 1220. Thus, a buffer structure can be provided between the heating plate 1300 and the atomizing matrix to prevent the heating plate 1300 from directly contacting the atomizing matrix, thereby preventing the atomizing matrix (e.g., smoke oil) from impacting the heating plate when the flow rate is too fast, resulting in it not being atomized and directly entering the atomization channel 1210. In some examples, the atomized matrix absorption material 1400 may include cotton. Cotton is composed of fibers that can absorb and guide oil, thereby better achieving the effect of buffering and avoiding excessive oil. In addition, cotton has the characteristic of evenly distributed pores, making the oil conduction smoother. In some examples, the shape of the atomized matrix absorption material 1400 can be adaptively set according to the angle at which the heating plate 1300 is placed. For example, as shown in Figure 3, when the heating plate 1300 is parallel to the extension direction L of the atomizing channel 1210, the longitudinal cross-section of the atomized matrix absorption material 1400 can be set to a rectangular shape. In other examples (described in detail below in conjunction with Figures 14 and 15), when the heating plate is angled with the extension direction of the atomizing channel, the longitudinal cross-section of the atomized matrix absorption material 1400 can be set to a trapezoidal shape, etc., so that one side covers the atomized matrix inlet 1140 and the other side is against the first surface of the heating plate 1300 opposite the opening 1220.

[0077] The atomizer core 1000 may also include an electrode 1500 (in the embodiment shown in FIG. 1 , two electrodes are included) for contacting the electrode contacts on the heating plate. The electrode 1500 can extend into the atomizer seat 1200 through the atomizer channel 1210 to contact the electrode contacts on the heating plate 1300. The shape and size of the electrode 1500 can be set according to the placement direction of the heating plate 1300 and / or the shape of the atomizer seat 1200. In the embodiments shown in FIG. 1 to FIG. 8 , the electrode 1500 can be set to have a Y-shaped structure on its upper portion so that after being inserted into the atomizer channel 1210, its side is in contact with the heating plate 1300. In addition, in the case where two heating plates are arranged opposite to each other, the electrode with a Y-shaped structure on the upper portion can simultaneously contact the electrode contacts on the two heating plates through the two branches of the Y-shaped structure.

[0078] In order to ensure that the electrode 1500 contacts the electrode contact during the assembly process, the atomizer seat 1200 may further define a limiting structure. For example, as shown in FIG8 , the atomizer seat 1200 defines a limiting structure 1240 on the side of the heating plate 1300 facing away from the outlet 1220. The limiting structure 1240 includes a limiting channel 1241, and the electrode 1500 is inserted into the limiting channel 1241 of the limiting structure 1240 to contact the electrode contact. The shape and size of the limiting channel 1241 can be adapted to the electrode 1500 to ensure the stability of the position of the electrode 1500 inserted into the atomizer seat 1200 relative to the atomizer seat 1200, so that the contact between the electrode 1500 and the electrode contact can be ensured even during the automated assembly process.

[0079] As shown in Figure 8, the electrode 1500 defines a first protrusion 1510 for abutting the inner wall of the limiting channel 1241. The first protrusion 1510 can be a convex portion of about 15° on the electrode 1500, for closely fitting with the inner wall of the limiting channel 1241 after being inserted into the limiting channel 1241. It should be understood that the first protrusion can also be set to a protrusion at other angles as needed. In some examples, as shown in Figure 8, the electrode 1500 can also define a first end 1530 and a second protrusion 1520 (for example, forming an electrode with a "cross" structure in the lower part) in sequence along the extension direction L of the atomizing channel 1210, and the second protrusion 1520 is used to abut against the limiting portion of the limiting structure 1240 to limit the position of the electrode 1500 along the extension direction L of the atomizing channel 1210.

[0080] As shown in Figures 4 and 8 , the limiting channel 1241 extends inward from the first end surface of the atomizer base 1200 near the air inlet 1110. Specifically, the limiting channels 1241 corresponding to the two electrodes 1500 both extend inward from the first end surface of the atomizer base 1200 near the air inlet 1110. This ensures that the two electrodes 1500 are assembled in the same direction, improving the convenience of assembling the electrodes 1500.

[0081] As shown in FIG8 , the limiting structure 1240 may further include a first limiting portion 1242 and a second limiting portion 1243. The first limiting portion 1242 is positioned adjacent to the heating plate 1300, while the second limiting portion 1243 is formed by the first end surface of the atomizer base 1200. At this point, the first end 1530 of the electrode 1500 abuts against the first limiting portion 1242, and the second protrusion 1520 abuts against the second limiting portion 1243. This further limits the position of the electrode 1500 along the extension direction L of the atomizer channel 1210, ensuring contact between the electrode 1500 and the electrode contacts even during automated assembly.

[0082] In some embodiments, the ends of the electrode 1500 and the atomizer seat 1200 near the air flow inlet 1110 are sealed with colloid to prevent the e-liquid from leaking from the bottom of the atomizer core 1000 and affecting the battery.

[0083] Figures 9 to 11 illustrate an atomizer core 2000 according to other embodiments of the present disclosure. The features of the atomizer core 2000 in Figures 9 to 11 are substantially the same as those of the atomizer core 1000 in Figures 1 to 8 , with the difference being that the atomizer core 2000 in Figures 9 to 11 is provided with two heating plates. Accordingly, the atomizer core housing 2100 is provided with atomizing substrate inlets at two locations corresponding to the heating plates, and the atomizer seat 2200 is provided with two openings.

[0084] Specifically, the atomizer core 2000 includes a first heating plate 2300 having the features of the heating plate 1300 shown in Figures 1 to 8, a first atomizing substrate inlet 2140 having the features of the atomizing substrate inlet 1140 shown in Figures 1 to 8, and a first opening 2220 having the features of the opening 1220 shown in Figures 1 to 8. In addition, the atomizer core housing further defines a second atomizing substrate inlet 2140', which is used to pass into the accommodation space and is opposite to the first atomizing substrate inlet 2140. Correspondingly, the atomizer seat also defines a second opening 2220', which is used to connect the second atomizing substrate inlet 2140' and the atomizing channel 2210 and is opposite to the first opening 2220. In addition, the atomizer core also includes a second heating plate 2300', which is arranged in the atomizing channel 2210 and is at least partially opposite to the second opening 2220'.

[0085] As shown in Figures 9 to 11, the first atomizing matrix inlet 2140 and the second atomizing matrix inlet 2140' are respectively formed on the two opposite side walls of the atomizing core housing. The first opening 2220 and the second opening 2220' are respectively formed on the two opposite side walls of the atomizing seat. The first heating plate 2300 is at least partially opposite to the first opening 2220, and the second heating plate 2300' is at least partially opposite to the second opening 2220', so that the atomizing matrix can reach the first heating plate 2300 through the first atomizing matrix inlet 2140 and the first opening 2220, and / or reach the second heating plate 2300' through the second atomizing matrix inlet 2140' and the second opening 2220'.

[0086] The features of the second heating plate 2300', the second opening 2220', and the second atomizing substrate inlet 2140' are respectively the same as the features of the heating plate 1300, the opening 1220, and the atomizing substrate inlet 1140 shown in Figures 1 to 8. It should be noted that the features of the first heating plate 2300 and the second heating plate 2300' can be the same or different, for example, they can be of different sizes. Similarly, the features of the first opening 2220 and the second opening 2220' can be the same or different, and the features of the first atomizing substrate inlet 2140 and the second atomizing substrate inlet 2140' can be the same or different.

[0087] Accordingly, a second atomized matrix adsorption material 2400' may also be provided for the second heating plate 2300'. The features of the second atomized matrix adsorption material 2400' are the same as those of the atomized matrix adsorption material 2400 shown in Figures 1 to 8.

[0088] In the above embodiment, the atomizer core 2000 may further include an electrode 2500 having the same features as the electrode 1500 shown in Figures 1 to 8. The electrode 2500 may be configured in a Y-shaped structure so that after being inserted into the retaining structure 2240, it can simultaneously contact the electrode contacts on the two opposing heating plates.

[0089] It should be understood that, in addition to the features described above, other features of the atomizer core 2000 (e.g., features of the limiting structure 2240, other features of the electrode 2500, etc.) may be the same as the corresponding features of the atomizer core 1000 described in Figures 1 to 8. For the sake of brevity, they will not be described in detail here.

[0090] Figures 12 to 21 show an atomizer core 3000 according to other embodiments of the present disclosure. Among them, the features of the atomizer core 3000 in Figures 12 to 21 are substantially the same as those of the atomizer core 1000 in Figures 1 to 8. The difference between the two is that the heating plate 3300 in the atomizer core 3000 in Figures 12 to 21 is arranged at a certain angle to the extension direction L of the atomization channel 3210 (i.e., tilted), thereby increasing the area of ​​the heating plate 3300 through which the air entering the atomization channel 3210 passes, as shown in Figure 15. By setting the angle between the heating plate 3300 and the extension direction L of the atomization channel 3210, the area of ​​the air entering the atomization channel 3210 through the heating plate 3300 can be changed, thereby changing the distribution characteristics of the formed aerosol. For the case of using tobacco oil as the atomization matrix, the taste of the aerosol can be changed.

[0091] The atomizing core 3000 may further include an atomizing matrix absorption material 3400. The longitudinal cross-section of the atomizing matrix absorption material 3400 may be set to a trapezoidal shape so that its first side covers the atomizing matrix inlet 3140 from the inner side of the atomizing core shell, and its second side opposite to the first side is abutted against the first surface of the heating plate 3300 opposite to the opening 3220.

[0092] The atomizer core 3000 may also include electrodes 3500, specifically, a first electrode 3510 and a second electrode 3520. The electrodes may extend through the atomizer channel 3210 into the atomizer base 3200 to contact electrode contacts on the heater plate 3300. The shape and size of the electrodes may be configured based on the placement orientation of the heater plate 3300 and / or the shape of the atomizer base 3200. In embodiments where the heater plate 3300 is tilted, the structures of the two electrodes of the atomizer core 3000 may differ. Specifically, the lengths of the two electrodes along the extension direction L of the atomizer channel 3210 may differ (as shown in Figures 14, 20, and 21), so that after being inserted into the atomizer channel 3210, the two electrodes may contact electrode contacts located at different depths on the heater plate 3300. Specifically, the length of the upper portion of the first electrode 3510 is shorter than the length of the upper portion of the second electrode 3520. In this case, the first and second electrodes are arranged in an upper and lower offset manner within the atomizer base. Accordingly, the two electrodes may be in an "L" shape.

[0093] To ensure contact between the electrodes and the electrode contacts during assembly, as shown in Figures 17 to 19, the atomizer base 3200 may further define a retaining structure 3240 on the side of the heater plate 3300 facing away from the opening 3220. The retaining structure 3240 may include at least one retaining channel 3241 and at least one ramp 3242. The second surface of the heater plate 3300, facing away from the opening or the inner wall of the atomizer core housing, abuts against the at least one ramp 3242. In this case, during assembly, after the heater plate 3300 is installed into the atomizer channel 3210, for example through the opening 3220, it can be positioned against the ramp 3242. The tilt angle of the ramp 3242 determines the tilt angle of the heater plate. After the heater plate 3300 is assembled, the first and second electrodes can be inserted through their respective retaining channels 3241 to contact the electrode contacts on the heater plate 3300.

[0094] Corresponding to the two electrodes, the atomizer base 3200 may define two inclined platforms 3242, which are respectively located at the ends of the two limiting channels 3240. The second surface of the heating plate 3300 abuts against the two inclined platforms 3242. This embodiment prevents the stepped platforms 3242 from blocking air in the atomization channel 3210 from passing through the heating plate 3300, thereby ensuring smoother aerosol inhalation.

[0095] It should be understood that, in addition to the features described above, other features of the atomizer core 3000 (e.g., features of the atomizer seat, other features of the electrode, etc.) may be the same as the corresponding features of the atomizer core 1000 described in Figures 1 to 8. For the sake of brevity, they will not be described in detail here.

[0096] Figures 22 to 28 illustrate atomizer cores 4000 according to other embodiments of the present disclosure. The features of the atomizer cores 4000 in Figures 22 to 28 are substantially the same as those of the atomizer core 1000 in Figures 1 to 8 , with the difference being that the atomizer seat 4200 and the atomizer core housing 4100 in the atomizer core 4000 in Figures 22 to 28 are cylindrical in shape.

[0097] The atomizer core 4000 may also include an electrode 4500, specifically, a first electrode 4510 and a second electrode 4520. Each electrode 4500 can extend into the atomizer seat 4200 through the atomizer channel 4210 to contact the electrode contacts on the heating plate 4300. The shape and size of the electrode 4500 can be set according to the placement direction of the heating plate 4300 and / or the shape of the atomizer seat 4200. In this embodiment, as shown in Figures 24, 27 and 28, the intermediate position of the first electrode 4510 defines a first bend 4511, and the end position of the second electrode 4520 defines a second bend 4521. At this time, the first electrode 4510 and the second electrode 4520 can be horseshoe-shaped, as shown in Figures 23 and 24.

[0098] To ensure contact between the electrode 4500 and the electrode contact during assembly, as shown in FIG8 , the limiting structure 4240 of the atomizer base 4200 includes two limiting channels. A first limiting channel 4241 extends inward from a first end surface of the atomizer base 4200 near the airflow inlet 4110, and a second limiting channel 4241′ extends inward from a second end surface of the atomizer base 4200, opposite the first end surface. The two limiting channels extending inward from different directions can save space in the atomizer base 4200, making the atomizer core 4000 more compact.

[0099] The first limiting channel 4241 further includes a third limiting portion 4242 having a stepped structure and being located adjacent to the heating plate 4300. The first bent portion 4511 abuts against the third limiting portion 4242. The second limiting channel 4241' further includes a fourth limiting portion 4242' formed by the second end surface of the atomizer seat 4200. The second bent portion 4521 abuts against the fourth limiting portion 4242'. This limits the positions of the first and second electrodes in the extension direction L of the atomizer channel 4210 so that they can contact the electrode contacts on the heating plate 4300 after being inserted into the limiting structure.

[0100] It should be understood that, in addition to the features described above, other features of the atomizer core 4000 (e.g., features of the atomizer core housing 4100 , other features of the electrode 4500 , etc.) may be the same as the corresponding features of the atomizer core 1000 described in FIG. 1 to FIG. 8 , and for the sake of brevity, they will not be described in detail here.

[0101] FIG29 shows an atomizer core 5000 according to some other embodiments of the present disclosure, wherein the features of the atomizer core 5000 in FIG5 are substantially the same as those of the atomizer core 4000 in FIG22 to FIG28 .

[0102] Different from the atomizer core housing 4100 in the atomizer core 4000 (which is provided with two atomizer substrate inlets 4140 ), the atomizer core housing 5100 of the atomizer core 5000 is provided with one atomizer substrate inlet 5140 .

[0103] In addition, the atomizer core 5000 may also include a leak-proof material 5600. The leak-proof material 5600 is disposed between the electrode 5500 and the atomizer core housing 5100 and abuts against the end of the atomizer seat 5200 near the air flow inlet 5110, thereby further preventing liquid leakage at the bottom of the atomizer core. In some embodiments, after applying glue between the electrode 5500, the atomizer core housing 5100, and the end of the atomizer seat 5200 near the air flow inlet 5110, the leak-proof material 5600 can be inserted between the atomizer core housing 5100 and the electrode 5500 at the air flow opening 5110 and abutted against the end of the atomizer seat 5200 near the air flow inlet 5110, thereby further promoting the leak-proof effect.

[0104] The leak-proof material 5600 can be made of cotton or other materials. The shape of the leak-proof material can match the shape of the atomizer core housing (for example, both are circular, etc.) so that it can be embedded in the atomizer core housing. In addition, the outer diameter of the leak-proof material 5600 can be slightly larger than the inner diameter of the atomizer core housing so that it can be embedded in the atomizer core housing through an interference fit, thereby improving the leak-proof effect.

[0105] An opening may be provided at a portion of the leakage-proof material 5600 opposite to the atomization channel 5210 , so that the airflow at the airflow inlet may pass through the opening and enter the atomization channel.

[0106] It should be understood that, in addition to the features described above, the other features of the atomizer core 5000 (e.g., features of the atomizer core housing 5100, other features of the electrode 5500, etc.) may be the same as the corresponding features of the atomizer core 4000 described in Figures 22 to 28. For the sake of brevity, they will not be described in detail here. In addition, it is understood that for the atomizer core of one or more of the above embodiments, a leak-proof material that is the same as or similar to the leak-proof material 5600 described with reference to Figure 29 may be provided.

[0107] Figures 30 to 36 illustrate an atomizer core 7000 according to other embodiments of the present disclosure. The features of the atomizer core 7000 in Figures 30 to 36 are substantially the same as those of the atomizer core 1000 in Figures 1 to 8 , with the difference being that the at least one heating plate 7300 of the atomizer core 7000 in Figures 30 to 36 is disposed within at least one opening 7220 . Accordingly, the atomization matrix absorption material 7400 is configured as a hollow cylindrical structure and is sleeved on the peripheral sidewall of the atomizer seat 7200 and located between the atomizer core housing 7100 and the atomizer seat 7200 .

[0108] Specifically, as shown in Figures 30 to 32, an atomizing matrix absorption material 7400 is provided between the atomizing core housing 7100 and the atomizing seat 7200. The atomizing matrix absorption material 7400 is sleeved on the peripheral side wall of the atomizing seat 7200 and has a first side and a second side opposite to the first side. The first side covers at least one atomizing matrix inlet 7140 from the inner side of the atomizing core housing 7100, and the second side is at least partially abutted against at least one heating plate 7300. Thus, a buffer structure can be provided between the heating plate and the atomizing matrix to prevent the heating plate from directly contacting the atomizing matrix, thereby preventing the atomizing matrix (e.g., smoke oil) from impacting the heating plate when the flow rate is too fast, thereby causing it to enter the atomizing channel 7210 directly without atomization. It should be understood that, except for the shape and setting position of the atomizing matrix absorption material 7400, which is different from the atomizing matrix absorption material 1400 of Figures 1 to 8, the other features are the same as those of the atomizing matrix absorption material of Figures 1 to 8, and will not be described in detail here.

[0109] In some embodiments, at least one fixed cover is provided between the atomizing matrix absorption material and the atomizing seat, wherein each fixed cover in the at least one fixed cover is used to limit a corresponding one of the at least one heating plate to an opening corresponding to the heating plate, and each fixed cover in the at least one fixed cover is defined with a window, and the window is relative to and communicates with an opening corresponding to the at least one opening and the atomizing matrix inlet corresponding to the opening. Specifically, as shown in Figures 31 to 33, a fixed cover 7600 is provided between the atomizing matrix absorption material 7400 and the atomizing seat 7200 for limiting the heating plate 7300 to an opening 7220. The fixed cover is arranged in the accommodating space 7130 and is relatively fixed to the atomizing seat 7200. In addition, the fixed cover 7600 is defined with a window 7640, and the window 7640 is relative to and communicates with the opening 7220 and the atomizing matrix inlet 7140, respectively. Thus, it is convenient to limit the heating plate to the opening, and does not affect the transfer of the atomized matrix from the atomizing matrix absorption material to the heating plate. Furthermore, the size of the window 7640 along the longitudinal direction of the atomizer core 7000 is smaller than the size of the heating plate 7300 (see FIG. 31 ), thereby ensuring that the heating plate is confined within the opening and does not escape from the window 7640 .

[0110] In some embodiments, each of the at least one fixed cover includes a first side wall, a second side wall, and a third side wall connected in sequence, wherein the first side wall, the second side wall, and the third side wall are coated on the peripheral side wall of the atomizing seat. Specifically, as shown in Figure 33, the fixed cover 7600 includes a first side wall 7610, a second side wall 7620, and a third side wall 7300 connected in sequence. The second side wall 7620 is opposite to the heating plate 7300. The first side wall 7610, the second side wall 7620, and the third side wall 7630 are coated on the outer periphery of the atomizing seat 7200. The above embodiment can achieve the reliably fixing of the heating plate in the opening.

[0111] In some embodiments, the window can be provided only on the second side wall opposite to the heating plate. Alternatively, as shown in Figure 33, the window 7640 can also extend from the first side wall 7610 through the second side wall 7620 to the third side wall 7630. In this case, as shown in Figures 33, 35 and 36, the portion of the peripheral side wall of the atomizer seat 7200 opposite to the portion of the window 7640 located on the first side wall 7610 is provided with a first snap 7651 extending outwardly, and the portion of the peripheral side wall of the atomizer seat 7200 opposite to the portion of the window located on the third side wall 7630 is provided with a second snap 7652 extending outwardly, the first snap 7651 and the second snap 7652 extend outward from the window 7640 and are fastened to the frame of the window 7640, that is, they are fastened to each other with the frame of the fixed cover corresponding to the window. The above embodiment can ensure that the fixed cover 7600 is positioned on the atomizer seat 7200, thereby further realizing that the heating plate is reliably confined within the opening.

[0112] In some embodiments, as shown in FIG. 33 , FIG. 35 and FIG. 36 , the first buckle 7651 and the second buckle 7652 are inclined in a direction away from the second side wall 7620 .

[0113] In some embodiments, at least one heating plate has a second surface facing the atomization channel 7210 provided with multiple electrode contacts. The atomizer core 7000 also includes multiple electrodes 7500 (e.g., a first electrode 7510 and a second electrode 7520) for contacting the multiple electrode contacts. This facilitates the electrodes extending from the atomization channel 7210 into the atomizer seat 7200 and contacting the electrode contacts. This further improves the ease of assembly of the atomizer core.

[0114] In order to ensure that the electrodes are in contact with the electrode contacts during the assembly process, the atomizer seat 7200 may also define a limiting structure 7240. The limiting structure includes a plurality of limiting channels connected to at least one opening, and a plurality of electrodes are respectively inserted into one of the plurality of limiting channels to contact one of the plurality of electrode contacts. Specifically, as shown in Figures 34 to 36, the limiting structure 7240 includes a first limiting channel 7241 and a second limiting channel 7242, and the first electrode 7510 and the second electrode 7520 are respectively inserted into the first limiting channel 7241 and the second limiting channel 7242. The shape and size of the limiting channel can be adapted to the electrode to ensure the stability of the position of the electrode inserted into the atomizer seat 7200 relative to the atomizer seat 7200, so that the contact between the electrode and the electrode contact can be ensured even in the automated assembly process.

[0115] In some embodiments, each of the plurality of electrodes defines a first portion located within a corresponding limiting channel and a second portion extending from the limiting channel into an opening connected to the limiting channel. As shown in FIG35 , the first electrode 7510 defines a first portion 7511 located within the first limiting channel 7241 and a second portion 7512 extending outward from the first portion 7511 (i.e., extending from the first limiting channel 7241 into an opening connected to the limiting channel), such that the electrode forms an L-shape. This shape facilitates the electrode extending from the limiting channel into the opening connected to the limiting channel to contact the electrode contacts on the heating plate within the opening. As shown in FIG36 , the second electrode 7520 defines a first portion 7521 located within the second limiting channel 7242 and a second portion 7522 extending outward from the first portion 7521, such that the electrode forms an L-shape. This shape facilitates the electrode extending from the second limiting channel 7242 into the opening connected to the limiting channel to contact the electrode contacts on the heating plate within the opening.

[0116] In some embodiments, the atomizer core 7000 may further include a bottom cover 7700, which closes the ends of the electrode and the atomizer seat 7200 close to the air flow inlet, thereby preventing the e-liquid from leaking from the bottom of the atomizer core and affecting the battery.

[0117] It should be understood that, in addition to the features described above, other features of the atomizer core 7000 (for example, features of the atomizer core housing 7100 , other features of the heating plate 7300 , etc.) may be the same as the corresponding features of the atomizer core 1000 described in FIG. 1 to FIG. 8 . For the sake of brevity, they will not be described in detail here.

[0118] According to another aspect of the present disclosure, an assembly method 2900 for an atomizer core 1000, 2000, 3000, 4000, 5000, or 7000 is provided. As shown in FIG37 , the assembly method 2900 may include: step S2901, inserting the electrode into the limiting structure of the atomizer seat; step S2902, installing at least one heating plate and an atomization matrix absorption material to the atomizer seat; step S2903, inserting the installed atomizer seat into the accommodating space of the atomizer core housing through the air flow inlet of the atomizer core housing; and step S2904, sealing the space between the electrode, the atomizer seat, and the atomizer core housing at the air flow inlet.

[0119] In some examples, step S2904, sealing the space between the electrode, the atomizer seat, and the atomizer core housing at the air flow inlet, may include injecting a colloid into the space between the electrode, the atomizer seat, and the atomizer core housing at the air flow inlet. In some other examples, step S2904, sealing the space between the electrode, the atomizer seat, and the atomizer core housing at the air flow inlet, may include sealing the space between the electrode, the atomizer seat, and the atomizer core housing at the air flow inlet using a bottom cover.

[0120] In some examples, the assembly method 2900 may further include: installing a leak-proof material on the end of the atomizer seat near the air flow inlet.

[0121] Although the various operations are depicted in the accompanying drawings as being in a specific order, this should not be understood as requiring that these operations must be performed in the specific order shown or in a sequential order, nor should it be understood as requiring that all illustrated operations must be performed to obtain the desired result. For example, step S2902 can be performed before step S2901. For another example, the installation of the heating plate or the installation of the atomized matrix adsorbent in step S2902 can be performed before step S2901.

[0122] In the case where the atomizer core is the atomizer core 1000 shown in Figures 1 to 8, the assembly method 2900 includes, for example: inserting the electrode 1500 into the limiting structure 1240 (specifically, the limiting channel 1241) of the atomizer seat 1200; sequentially installing the heater plate 1300 and the atomized matrix adsorption material 1400 into the atomizer seat 1200, for example, inserting the heater plate into the atomizer seat 1200 from the upper side of the atomizer seat 1200 as shown in Figure 7, and inserting the atomized matrix adsorption material 1400 into the opening 1220; inserting the installed atomizer seat 1200 into the receiving space 1130 of the atomizer core housing 1100 through the air flow inlet 1110; and injecting the colloid between the electrode 1500, the atomizer seat 1200, and the atomizer core housing 1100 at the air flow inlet 1110. In some examples, the electrode may be installed first and then the heater plate, in which case the electrode may serve as a support for the heater plate.

[0123] In the case where the atomizer core is the atomizer core 2000 in FIG. 9 to FIG. 11 , the assembly method 2900 is, for example, as follows: inserting the electrode 2500 into the limiting structure 2240 (specifically, the limiting channel 2241 ) of the atomizer seat 2200 ; inserting the first heating plate 2300 The second heating plate 2300' and the first and second atomized matrix absorbing materials 2400 and 2400' are installed in the atomizer seat 2200. For example, the first and second heating plates are inserted into the atomizer seat 2200 from above as shown in FIG. 10 , and the first and second atomized matrix absorbing materials are respectively embedded in the first opening 2220 and the second opening 2220'; the installed atomizer seat 2200 is inserted into the receiving space 2130 of the atomizer core housing 2100 through the air flow inlet 2110; and the colloid is injected between the electrode 2500, the atomizer seat 2200, and the atomizer core housing 2100 at the air flow inlet 2110. In some examples, the electrodes may be installed first and then the heating plates. In this case, the electrodes may serve as a support for the heating plates.

[0124] When the atomizer core is the atomizer core 3000 in Figures 12 to 21, the assembly method 2900 is, for example: installing the heating plate 3300 and the atomization matrix absorption material 3400 into the atomizer seat 3200, for example, installing them from the opening 3220, so that the heating plate 3300 rests on the inclined platform 3242 of the limiting structure 3240; inserting the electrode 3500 into the limiting structure 3240 (specifically, the limiting channel 3241) of the atomizer seat 3200, so that the electrode 3500 contacts the electrode contact on the heating plate 3300; inserting the installed atomizer seat 3200 into the accommodating space 3130 of the atomizer core shell 3100 from the air flow inlet 3110; and injecting colloid between the electrode 3500, the atomizer seat 3200 and the atomizer core shell 3100 at the air flow inlet 3110. It is understandable that the order of installing the heating plate, the atomized matrix absorption material and the electrode can be changed. For example, the step of installing the electrode can be performed first, and then the step of installing the heating plate and the atomized matrix absorption material can be performed. The present disclosure is not limited to this.

[0125] In the case where the atomizer core is the atomizer core 4000 in Figures 22 to 28, the assembly method 2900 is, for example, as follows: inserting the first electrode 4510 from the first end face of the atomizer seat 4200 close to the air flow inlet 4110 into the first limiting channel 4241 of the atomizer seat 4200, and inserting the second electrode 4510' from the second end face of the atomizer seat 4200 away from the air flow inlet 4110 into the second limiting channel 4241' of the atomizer seat 4200; inserting the heating plate 4300 and the atomization matrix absorption material 4400 into the atomizer seat 4200; The atomizer seat 4200 is installed, for example, by inserting the heating plate into the atomizer seat 4200 from above as shown in FIG. 26 , and inserting the atomized matrix absorption material 4400 into the opening 4220; inserting the installed atomizer seat 4200 into the receiving space 4130 of the atomizer core housing 4100 through the air flow inlet 4110; and injecting the colloid between the first electrode 4510 and the second electrode 4520, the atomizer seat 4200, and the atomizer core housing 4100 at the air flow inlet 4110. In some examples, the electrodes may be installed first and then the heating plate, in which case the electrodes may serve as a support for the heating plate.

[0126] When the atomizer core is the atomizer core 7000 in Figures 30 to 36, the assembly method 2900 is, for example: inserting the first electrode 7510 and the second electrode 7520 into the first limiting channel 7241 and the second limiting channel 7242 of the limiting structure 7240 of the atomizer seat respectively; installing the heating plate 7300, the fixing cover 7600 and the atomization matrix absorption material 7400 to the atomizer seat 7200 in sequence; inserting the installed atomizer seat 7200 into the accommodating space 7130 of the atomizer core shell 7100 from the air flow inlet 7110; and using the bottom cover 7700 at the air flow inlet 7110 to close the space between the electrode 7500, the atomizer seat 7200 and the atomizer core shell 7100.
