Description

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

The present disclosure relates to the field of atomization technology, and in particular to an atomization core, an atomizer, an electronic cigarette including the atomization core, and an assembly method for the atomization core.

Background Art

An electronic cigarette (also called an "electronic cigarette") or a smoking device is an electronic delivery system for generating an aerosol from an atomized substrate for a user to inhale. The atomized substrate can be a liquid (e.g., a smoke liquid, etc.) or a solid or gel (e.g., a smoke paste), etc.

Generally, a conventional electronic cigarette mainly includes a cartridge storing an atomized matrix and a power supply device. The cartridge has a heating or evaporation device, such as an atomizer including an atomizer core. The power supply device supplies power to the atomizer core to convert the atomized matrix in the cartridge into an aerosol for the user to inhale. In many electronic cigarettes, the user's inhalation activates the atomizer core, vaporizing the liquid atomized matrix in the cartridge, and then the user inhales the generated aerosol through the mouthpiece.

The atomizer core is a key component in electronic cigarettes, which directly affects 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.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

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 components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

In the present disclosure, unless otherwise clearly specified and limited, the terms "connected", "fixed", etc. should be understood in a broad sense, for example, it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

In this article, "communication" refers to fluid communication, that is, fluid (including liquid and/or gas) can flow from one component to another component. In addition, in this article, communication between two components can refer to direct communication between the two components, for example, at least partial alignment between two holes, or communication through an intermediate medium.

In the present disclosure, unless otherwise stated, all numbers used in the specification and claims to represent component parameters, technical effects, etc. should be understood as being modified by the term "approximately" or "roughly" in any case. Therefore, unless otherwise indicated, the numerical parameters listed in the following specification and the attached 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.

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

"Atomized substrate" refers to a mixture or auxiliary substance that can be completely or partially atomized into an aerosol by an electronic device or similar device. The atomized substrate can be a liquid medium such as e-cigarette liquid, medical drugs, skin care lotion, etc. By atomizing these media, an aerosol that can be inhaled or absorbed can be delivered to the user.

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

"Atomizer" refers to a device that forms aerosol from stored atomizable substrate, i.e., atomized substrate, by heating or ultrasound. The atomizer core is one of the main components of the atomizer.

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 cotton periphery, 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 the smoke oil and transmit it to the heating wire, and then atomize it by heating the heating wire smoke oil and the like. In the related art, the pores in the cotton and ceramic are irregular, resulting in individual differences in oil locking and oil conduction, and the taste consistency of the smoke generated 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 many and complicated (especially the assembly and welding of heating wires are very complicated), which leads to problems such as low production efficiency, high scrap rate, and large individual differences of the heating cores in the related art, and cannot meet the requirements of standardized and modular assembly.

In view of this, the present disclosure proposes a highly integrated atomizer core. By modularly arranging the various components in the atomizer core, the integration level of the atomizer core can be improved, so that the atomizer core can meet the requirements of standardized 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 modularly produced, and the assembly of the various components can be completed automatically, thereby improving product production efficiency and stability.

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

The atomizer core of the present disclosure will be described in detail below with reference to FIGS. 1 to 28 .

According to one or more embodiments of the present disclosure, the atomizer core is used to atomize the atomizer substrate to form an aerosol, and the atomizer core includes: an atomizer core shell, the atomizer core shell defines an airflow inlet, an airflow outlet, a storage space between the airflow inlet and the airflow outlet, and at least one atomizer substrate inlet, and the at least one atomizer substrate inlet leads to the storage space; an atomizer seat, the atomizer seat An atomizing channel and at least one opening are defined in the accommodating space and are used to communicate with an air flow inlet and an air flow outlet, and the at least one opening is used to communicate with at least one atomizing substrate inlet and the atomizing channel; and at least one heating plate is disposed in the atomizing channel and is respectively at least partially opposite to one or more of the at least one opening.

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 middle atomization substrate inlet among the three atomization substrate 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.

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

The atomizer core housing 1100 defines an airflow inlet 1110, an airflow outlet 1120, a receiving space 1130 between the airflow inlet 1110 and the airflow 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 penetrates the atomizer core housing wall, so that the space outside the atomizer core housing and the receiving space 1130 can be connected, so that the atomizer substrate 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.

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

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

In the above embodiment, as shown in FIG. 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 atomizing channel 1210 in the atomizing seat 1200, thereby forming an airflow passage. A portion of the airflow passage (i.e., the atomizing channel 1210) forms an atomizing chamber. 1220 is in communication with the atomization substrate inlet 1140, and the other side thereof is in communication with the air fluid in the atomization channel 1210. The atomization substrate outside the atomization core housing penetrates into the heating sheet 1300 through the atomization substrate inlet 1140 and the opening 1220, and in the example where the heating sheet 1300 is a heating sheet with micropores, it can continue to penetrate into the interior of the heating sheet 1300, and evaporate to form steam after being heated and atomized by the heating sheet 1300. The steam is entrained in the air flowing through the atomization channel 1210 to form an aerosol for the user to inhale.

The above embodiment provides a simple and compact atomizer core 1000, which improves the integration of the atomizer core 1000. The atomizer core housing, atomizer seat, and heating plate of the atomizer core 1000 can be designed as standardized or modular components, so that the atomizer core 1000 can meet the requirements of standardized or modular assembly, thereby improving production efficiency and product stability.

The atomizer core housing 1100 is a hollow structure for providing an installation space for the atomizer seat 1200, and forming an airflow passage for air to flow through 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, a cylindrical shape (as shown in Figures 22 and 23), or an elliptical cylindrical shape (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 an accommodating space 1130) for accommodating the atomizer seat 1200 and a mouth for providing an airflow outlet 1120. Among them, the accommodating portion may be set to a cylindrical shape or an elliptical cylindrical shape, etc., to match the shape of the atomizer seat 1200 accommodated. The mouth may be set to a cylindrical shape with a cross-sectional area smaller than that of the accommodating portion, so that the user can inhale.

In some embodiments, the atomizing substrate inlet 1140 provided on the atomizing core housing 1100 for accessing the accommodating space 1130 may be provided 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 may be provided as required, for example, according to a predetermined atomizing substrate flow rate, or, for example, may be provided to be less than or equal to the size of the heating plate, etc.

The shape and size of the airflow inlet 1110 provided on the atomizer core housing 1100 can be set so that the atomizer seat 1200 can be arranged in the accommodation space 1130 through the airflow inlet 1110. Thus, it is convenient for the atomizer seat 1200 to enter from the airflow inlet 1110 and be installed in the accommodation space 1130, and it is particularly convenient to automatically install the atomizer seat 1200 in the accommodation space 1130 through an automated installation device. Specifically, for example, the size of the airflow 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 airflow inlet 1110 can be set to match the shape of the cross section of the atomizer seat 1200. Similarly, in some examples, the size of the accommodation 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 accommodation space 1130.

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

As shown in FIGS. 4 to 7 , the atomization channel 1210 in the atomizer seat 1200 may be configured as at least one through hole or through groove, and its extension direction L may be consistent with the extension direction of the airflow passage of the atomizer core housing 1100 so as to connect the airflow inlet 1110 and the airflow outlet 1120 .

As shown in Figure 7, the opening 1220 on the atomizing seat 1200 can be set 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. 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, referring to Figure 5, a guide rail 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 rail and moved to the step along the guide rail. Thus, it is convenient to automatically install the heating plate 1300 into 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 may 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 may be set to be slightly larger than the size of the heating plate 1300, or the size of the opening 1220 may be set to be slightly smaller than the size of the heating plate 1300 and the heating plate 1300 may pass through, for example, slightly tilted, and/or the shape of the opening 1220 may be set to match the shape of the heating plate 1300.

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, 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, so as to substantially separate 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 atomizer seat 1200 after the accommodating space 1130 is inserted, and the protrusion 1230 arranged 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 more closely matched to prevent leakage, for example, to prevent 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 arranged only on one or two sides of the atomizer seat 1200. For example, as shown in Figure 7, two protrusions 1230 are respectively arranged on the relatively flat front and rear sides of the atomizer seat 1200, and the curved 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 atomization matrix, even if the protrusion 1230 is only provided around a portion of the periphery of the atomization seat 1200 , the surface tension of the oil itself can well prevent the oil from leaking out.

As shown in FIG. 4 , the heating sheet 1300 disposed in the atomization channel 1210 of the atomization seat 1200 may be arranged to be parallel to the extension direction L of the atomization channel 1210. At this time, the area of the air entering the atomization channel 1210 passing through the heating sheet 1300 is small. Alternatively, the heating sheet may also be arranged to be at a certain angle to the extension direction L of the atomization channel, for example, at an angle of about 15 degrees (as shown in FIG. 15 ), thereby increasing the area of the heating sheet 1300 through which the air entering the atomization channel 1210 passes. By changing the angle between the heating sheet and the extension direction of the atomization channel, the area of the heating sheet 1300 through which the air entering the atomization channel passes 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.

The surface of the heating plate 1300 is provided with an electrode contact. The electrode contact can be provided on the second surface of the heating plate 1300 away from the outlet 1220 to avoid contact between the electrode contact and the e-liquid, etc., and facilitate the electrode 1500 to extend from the atomization channel 1210 into the atomization seat 1200 and contact the electrode contact. This can further improve the assembly convenience of the atomization core 1000.

The heating plate 1300 may be a sheet structure provided with a plurality of micropores, and the plurality of micropores are used to adsorb the atomized matrix through capillary action. In this way, not only the amount of atomized matrix such as smoke oil adsorbed can be controlled or increased, but also the oil intake can be made more uniform, thereby making the formed aerosol softer and having a better taste consistency. In addition, when the atomized matrix supplied to the heating plate 1300 is exhausted, the atomized matrix stored in the micropores of the heating plate 1300 can avoid dry burning of the heating plate and avoid the generation of burnt smell. In some examples, the plurality of micropores on the heating plate 1300 can be formed by laser or chemical corrosion to ensure the uniformity of the plurality of micropores formed, thereby further promoting the increase in the amount of atomized matrix such as smoke oil adsorbed. In some examples, the aperture of the plurality of micropores can be set to micrometer level. Thus, the tension of atomized matrix such as smoke oil can be used to prevent it from penetrating the heating plate 1300 into the atomization channel, thereby reducing the risk of leakage. In some examples, a metal coating for heating the atomized matrix is provided on one side of the sheet structure of the heating plate 1300. In some examples, the heating sheet 1300 may be made of glass, ceramic, mica, or the like.

As shown in FIG4 , the first surface of the heating plate 1300 facing the opening 1220 is against the inner wall of the atomizer seat 1200, and the first surface is sealed with the inner wall of the atomizer seat 1200 by a colloid, for example. Thus, the tobacco oil entering the atomization matrix inlet 1140 and the opening 1220 can be prevented 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 be against the inner wall of the atomizer seat 1200, and the two are sealed by a seal.

In order to further reduce the risk of leakage, the atomizer core 1000 may also include an atomizing matrix absorption material 1400. For the e-liquid, 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 inner side of the atomizing core shell, and its 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 avoid The heating plate 1300 is in direct contact with the atomization substrate, so as to avoid the atomization substrate (e.g., smoke oil) from impacting the heating plate when the flow rate is too fast, thereby causing it to enter the atomization channel 1210 directly without atomization. In some examples, the atomization substrate absorption material 1400 may include cotton. Cotton is composed of fibers, which can achieve the effects of oil absorption and oil conduction, thereby better achieving the effect of buffering and avoiding excessive oil. In addition, cotton has the characteristics of uniform distribution of pores, making the oil conduction smoother. In some examples, the shape of the atomization substrate absorption material 1400 can be adaptively arranged according to the angle of the heating plate 1300 placement, for example, as shown in Figure 3, when the heating plate 1300 is parallel to the extension direction L of the atomization channel 1210, the longitudinal section of the atomization substrate absorption material 1400 can be set to a rectangle. 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 atomization channel, the longitudinal cross-section of the atomization matrix absorption material 1400 can be set to a trapezoid, etc., so that one side of it covers the atomization matrix inlet 1140 and the other side is attached to the first surface of the heating plate 1300 opposite to the opening 1220.

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 FIGS. 1 to 8 , the electrode 1500 can be set to have a Y-shaped structure in 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 oppositely, the electrode with a Y-shaped structure in the upper portion can contact the electrode contacts on the two heating plates at the same time through the two branches of the Y-shaped structure.

In order to ensure that the electrode 1500 contacts the electrode contact during the assembly process, the atomizer seat 1200 may also 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 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 in the automated assembly process.

As shown in Figure 8, the electrode 1500 defines a first protrusion 1510 for abutting against 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 being closely matched with the inner wall of the limiting channel 1241 after being inserted into the limiting channel 1241. It should be understood here that the first protrusion can also be set as a protrusion at other angles as needed. In some examples, as shown in Figure 8, the electrode 1500 can also define the first end 1530 and the 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 atomization 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 atomization channel 1210.

As shown in Figures 4 and 8, the limiting channel 1241 extends inwardly from the first end surface of the atomizer seat 1200 close to the air flow inlet 1110. Specifically, the limiting channels 1241 corresponding to the two electrodes 1500 extend inwardly from the first end surface of the atomizer seat 1200 close to the air flow inlet 1110. In this way, the assembly directions of the two electrodes 1500 can be the same, which improves the convenience of assembling the electrodes 1500.

As shown in FIG8 , the limiting structure 1240 may further include a first limiting portion 1242 and a second limiting portion 1243, wherein the first limiting portion 1242 is disposed close to the heating plate 1300, and the second limiting portion 1243 is formed by the first end surface of the atomizing seat 1200. At this time, 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. Thus, the position of the electrode 1500 along the extension direction L of the atomizing channel 1210 can be further limited, so that the electrode 1500 can be ensured to contact the electrode contact even in the automated assembly process.

In some embodiments, the ends of the electrode 1500 and the atomizer seat 1200 close to the air flow inlet 1110 are sealed with the atomizer core housing 1100 by colloid, thereby preventing the e-liquid from leaking from the bottom of the atomizer core 1000 and affecting the battery.

Figures 9 to 11 show 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, except 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 atomization substrate inlets at two locations corresponding to the heating plates, and the atomizer seat 2200 is provided with two openings.

Specifically, the atomizing 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 atomizing 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 atomizing seat also defines a second opening 2220', which is used to communicate the second atomizing substrate inlet 2140' and the atomizing channel 2210 and is opposite to the first opening 2220. In addition, the atomizing 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'.

As shown in Figures 9 to 11, the first atomization substrate inlet 2140 and the second atomization substrate inlet 2140' are respectively formed on two opposite side walls of the atomization core housing. The first opening 2220 and the second opening 2220' are respectively formed on two opposite side walls of the atomization 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 atomization substrate can reach the first heating plate 2300 through the first atomization substrate inlet 2140 and the first opening 2220, and/or reach the second heating plate 2300' through the second atomization substrate inlet 2140' and the second opening 2220'.

Among them, the features of the second heating plate 2300', the second opening 2220' and the second atomization substrate inlet 2140' are respectively the same as the features of the heating plate 1300, the opening 1220 and the atomization substrate inlet 1140 shown in Figures 1 to 8. It should be noted here that the features of the first heating plate 2300 and the second heating plate 2300' can be set to be the same or different, for example, set to different sizes, etc. Similarly, the features of the first opening 2220 and the second opening 2220' can be set to be the same or different, and the features of the first atomization substrate inlet 2140 and the second atomization substrate inlet 2140' can be set to be the same or different.

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 Figs. 1 to 8 .

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 as a Y-shaped structure so that after being inserted into the limiting structure 2240, it simultaneously contacts the electrode contacts on the two opposite heating plates.

It should be understood that, in addition to the features described above, other features of the atomizer core 2000 (for example, 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, and for the sake of brevity, they will not be described in detail here.

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 the features 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 (i.e., tilted arrangement) to the extension direction L of the atomization channel 3210, 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.

The atomizer core 3000 may also include an atomizer matrix absorption material 3400, and the longitudinal section of the atomizer matrix absorption material 3400 may be set to a trapezoidal shape so that its first side covers the atomizer matrix inlet 3140 from the inner side of the atomizer core shell, and its second side opposite to the first side is attached to the first surface of the heating plate 3300 opposite to the opening 3220.

The atomizer core 3000 may further include an electrode 3500, specifically, a first electrode 3510 and a second electrode 3520. The electrode may extend into the atomizer seat 3200 through the atomization channel 3210 to contact the electrode contacts on the heating plate 3300. The shape and size of the electrode may be set according to the placement direction of the heating plate 3300 and/or the shape of the atomizer seat 3200. In an embodiment where the heating plate 3300 is arranged obliquely, the structures of the two electrodes of the atomizer core 3000 may be different. Specifically, the lengths of the two electrodes along the extension direction L of the atomization channel 3210 are different (as shown in Figures 14, 20 and 21), so that the two electrodes can respectively contact the electrode contacts located at different depths of the heating plate 3300 after being inserted into the atomization channel 3210. 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. At this time, the first electrode and the second electrode are arranged in an up-down staggered manner in the atomizer seat. Accordingly, the shape of the two electrodes can be "L" shaped.

In order to ensure that the electrode contacts the electrode during the assembly process, as shown in Figures 17 to 19, the atomizer seat 3200 may further define a limiting structure 3240 on the side of the heating plate 3300 away from the opening 3220, and the limiting structure 3240 may include at least one limiting channel 3241 and at least one inclined platform 3242. The second surface of the heating plate 3300 away from the opening or away from the inner wall of the atomizer core housing is against at least one inclined platform 3242. In this case, during the assembly process, after the heating plate 3300 is installed into the atomization channel 3210 through the opening 3220, for example, the heating plate 3300 can be abutted against the inclined platform 3242, thereby achieving the positioning of the heating plate 3300, and the inclination angle of the inclined platform 3242 determines the inclination angle of the heating plate. After the heating plate 3300 is assembled, the first electrode and the second electrode can be inserted through the corresponding limiting channels 3241 respectively to contact the electrode contacts on the heating plate 3300.

Corresponding to the two electrodes, the atomizer seat 3200 may define two inclined platforms 3242, which are respectively located at the ends of the two limiting channels 3240, and the second surface of the heating plate 3300 is attached to the two inclined platforms 3242. The above embodiment can prevent the stepped platforms 3242 from blocking the air in the atomization channel 3210 from passing through the heating plate 3300, so that the aerosol can be inhaled more smoothly.

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 FIGS. 1 to 8 , and for the sake of brevity, they will not be described in detail here.

Figures 22 to 28 show 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 the features of the atomizer core 1000 in Figures 1 to 8, except 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.

The atomizer core 4000 may also include an electrode 4500, specifically, a first electrode 4510 and a second electrode 4520. Each electrode 4500 may 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 may 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 may be horseshoe-shaped, as shown in Figures 23 and 24.

In order to ensure that the electrode 4500 contacts the electrode contact during the assembly process, as shown in FIG8 , the limiting structure 4240 of the atomizer seat 4200 includes two limiting channels, a first limiting channel 4241 of the two limiting channels extending inwardly from a first end surface of the atomizer seat 4200 close to the air flow inlet 4110, and a second limiting channel 4241′ of the two limiting channels extending inwardly from the atomizer seat 4200 close to the air flow inlet 4110. The second end face opposite to the first end face extends inward. The two limiting channels extending inward from different directions can save space of the atomizer seat 4200, making the atomizer core 4000 more compact.

The first limiting channel 4241 further includes a third limiting portion 4242, which is a step structure and is close to the heating plate 4300, and the first bending portion 4511 abuts against the third limiting portion 4242, and the second limiting channel 4241' further includes a fourth limiting portion 4242', which is formed by the second end surface of the atomizing seat 4200, and the second bending portion 4521 abuts against the fourth limiting portion 4242'. In this way, the positions of the first electrode and the second electrode in the extension direction L of the atomizing channel 4210 can be limited, so that the first electrode and the second electrode can contact the electrode contacts on the heating plate 4300 after being inserted into the limiting structure.

It should be understood that, in addition to the features described above, other features of the atomizer core 4000 (for example, 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 FIGS. 1 to 8 , and for the sake of brevity, they will not be described in detail herein.

Fig. 29 shows an atomizer core 5000 according to some other embodiments of the present disclosure. The features of the atomizer core 5000 in Fig. 5 are substantially the same as the features of the atomizer core 4000 in Figs. 22 to 28 .

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 .

In addition, the atomizer core 5000 may also include a leak-proof material 5600, which 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 leakage at the bottom of the atomizer core. In some embodiments, after gluing 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 may be plugged between the atomizer core housing 5100 and the electrode 5500 at the air flow opening 5110 and abuts against the end of the atomizer seat 5200 near the air flow inlet 5110, thereby further promoting the leak-proof effect.

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 round, etc.) so as to 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 interference fit, thereby promoting the leak-proof effect.

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

It should be understood that, in addition to the features described above, 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 FIGS. 22 to 28, and 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 or similar to the leak-proof material 5600 described with reference to FIG. 29 may be provided.

Figures 30 to 36 show the 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 the features of the atomizer core 1000 in Figures 1 to 8, and the difference between the two is that at least one heating plate 7300 of the atomizer core 7000 in Figures 30 to 36 is respectively arranged in at least one opening 7220. Accordingly, the atomization matrix absorption material 7400 is arranged in a hollow cylindrical structure, and is sleeved on the peripheral side wall of the atomizer seat 7200 and is located between the atomizer core housing 7100 and the atomizer seat 7200.

Specifically, as shown in Figures 30 to 32, an atomizing matrix absorbing material 7400 is provided between the atomizing core housing 7100 and the atomizing seat 7200. The atomizing matrix absorbing 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 attached to 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 (for example, smoke oil) from impacting the heating plate when the flow rate is too fast, thereby causing it to directly enter the atomizing channel 7210 without atomization. It should be understood here that the atomizing matrix absorbing material 7400 is different from the atomizing matrix absorbing material 1400 of Figures 1 to 8 in terms of shape and setting position, and the other features are the same as the atomizing matrix absorbing material of Figures 1 to 8, and will not be described in detail here.

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 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 at least one fixed cover is defined with a window, and the window is opposite and connected to 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 the opening 7220. The fixed cover is arranged in the accommodation 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 opposite and connected to the opening 7220 and the atomizing matrix inlet 7140 respectively. Thus, it is convenient to limit the heating plate to the opening, and the atomizing matrix is not affected 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 will not escape from the window 7640 .

In some embodiments, each fixed cover in 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 periphery of the atomizing seat 7200. The above embodiment can realize that the heating plate is reliably fixed in the opening.

In some embodiments, the window may be arranged only on the second side wall opposite to the heating plate. Alternatively, as shown in Figure 33, the window 7640 may 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 peripheral side wall of the atomizer seat 7200 and the portion of the window 7640 located on the first side wall 7610 are opposite to each other. The portion of the peripheral side wall of the atomizer seat 7200 and the portion of the window located on the third side wall 7630 is provided with a second buckle 7652 extending outward, and the first buckle 7651 and the second buckle 7652 extend outward from the window 7640 and are buckled on the frame of the window 7640, that is, the frame corresponding to the window of the fixed cover is buckled with each other. The above embodiment can ensure that the fixed cover 7600 is positioned on the atomizer seat 7200, so that the heating plate can be further reliably restricted in the opening.

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

In some embodiments, at least one heating plate is provided with a plurality of electrode contacts on the second surface facing the atomization channel 7210, and the atomization core 7000 further includes a plurality of electrodes 7500 (e.g., a first electrode 7510 and a second electrode 7520) for contacting the plurality of electrode contacts. Thus, it is convenient for the electrode to extend from the atomization channel 7210 into the atomization seat 7200 and contact the electrode contacts. Thus, the assembly convenience of the atomization core can be further improved.

In order to ensure that the electrode contacts the electrode 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 in a limiting channel in the plurality of limiting channels to contact an electrode contact in 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 in 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.

In some embodiments, each electrode in a plurality of electrodes defines a first portion located in a corresponding limiting channel and a second portion extending from the limiting channel to an opening in communication with the limiting channel.
