Description

Heating plate, atomizer core, atomizer and electronic cigarette Technical Field

[0001] The present disclosure relates to the field of atomization technology, and in particular to a heating plate, an atomization core, an atomizer, and an electronic cigarette including the atomization 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 heating plates in atomizer cores suffer from uneven heating and easy burning. Therefore, it is necessary to provide a heating plate and atomizer core that offer a stable taste, uniform oil supply, and resistance to burning.

[0009] According to yet 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.

[0010] According to one or more embodiments of the present disclosure, the present disclosure provides a heating sheet, which includes an atomized matrix absorption matrix and a heating body. By providing a plurality of pores for adsorbing the atomized matrix in the atomized matrix absorption matrix, and the plurality of pores are arranged according to a preset rule, the atomized matrix can be directly heated by passing through the plurality of pores in the atomized matrix absorption matrix to the heating body, thereby making the heating contact area larger, the heating more uniform, and improving the uniformity and rate of providing the atomized matrix through the heating sheet, so that the formed aerosol is softer and more consistent, and is not prone to problems such as core sticking.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] "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.

[0035] "Aerosol" refers to a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium.

[0036] 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.

[0037] In the related art, the heating element within the atomizer core primarily has two structures: a cotton heating core and a ceramic heating core. Cotton heating cores typically wrap a heating wire around an oil-conducting cotton core, which is powered by a battery to heat the heating wire. Once the heating wire reaches a certain temperature, the atomized matrix adsorbed on the oil-conducting cotton begins to volatilize. In cotton heating cores, the oil-conducting cotton core is in direct contact with the heating wire, causing the atomized matrix around the heating wire to evaporate rapidly, resulting in a dry burn. After the atomized matrix evaporates, the oil-conducting cotton core is easily burned by the heating wire, affecting the flavor of the vapor. Furthermore, compared to cotton cores, ceramic heating cores use a sintering process to sinter the ceramic around the heating wire. Because the ceramic in ceramic heating cores is sintered, even though the ceramic is heat-resistant, its inherent properties still result in irregular porosity distribution within the sintered ceramic core, resulting in unstable flavor.

[0038] In view of this, the present disclosure provides a heating plate, which includes an atomized matrix absorption matrix and a heating body. By providing multiple pores for adsorbing the atomized matrix in the atomized matrix absorption matrix, and the multiple pores are arranged according to preset rules, the atomized matrix can be directly passed through the multiple pores in the atomized matrix absorption matrix to reach the heating body for heating, thereby making the heating contact area larger and the heating more uniform, and improving the uniformity and rate of providing the atomized matrix through the heating plate, so that the formed aerosol is softer and more consistent, and is not prone to problems such as core sticking.

[0039] The heating sheet disclosed in the present invention can achieve the advantages of both the taste restoration of the cotton core and the high stability of the ceramic core, but at the same time overcome the problems of poor consistency of the ceramic atomization core and poor durability of the cotton core in the prior art. In addition, compared with the cotton heating core (which requires manual assembly), the heating sheet disclosed in the present invention can be automated through the setting of a jig, thereby improving production efficiency. Moreover, by directly providing a plurality of pores for oil conduction in the base supporting the heating body, the components of the heating sheet can be reduced and the thickness of the heating sheet can be reduced.

[0040] 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. 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 in other equipment that requires atomization of the atomizing matrix, such as medical atomizers, skin care instruments, aromatherapy devices, etc.

[0041] The heating plate and the atomizing core of the present disclosure will be described in detail below with reference to FIG. 1 to FIG. 9 .

[0042] FIG. 1 is a perspective view of a heating sheet 10 according to some embodiments of the present disclosure; FIG. 2 is a perspective view of the heating sheet of FIG. 1 from another angle; and FIG. 3 is an exploded view of the heating sheet of FIG. 1 .

[0043] As shown in FIG. 1 to FIG. 3 , a heating plate 10 for atomizing an atomizing matrix to form an aerosol may include an atomizing matrix absorption base 11 and a heating body 12 .

[0044] The atomized matrix absorption matrix 11 is provided with a plurality of pores arranged according to a preset rule, and the heating body 12 is provided on the surface of the atomized matrix absorption matrix 11 , wherein the plurality of pores are used to adsorb the atomized matrix and guide the adsorbed atomized matrix to the heating body 12 .

[0045] In the above-mentioned embodiment, the atomized matrix reaches the heater 12 under the absorption and guiding effect of the multiple pores arranged according to the preset rules in the atomized matrix absorption matrix 11, so as to be heated and atomized at the heater 12. The above-mentioned embodiment directly attaches the heater to the atomized matrix absorption matrix provided with multiple pores, so that the heating contact area is larger and the heating is more uniform. In addition, the multiple pores arranged according to the preset rules (that is, distributed with a certain regularity) can improve the uniformity and rate of the atomized matrix provided by the atomized matrix absorption matrix. This can cause the formed aerosol to be softer and more consistent, and is not prone to problems such as sticking the core. In addition, by directly arranging multiple pores for oil conduction in the matrix supporting the heater, the components of the heating plate can also be reduced, and the thickness of the heating plate can be reduced.

[0046] The multiple pores of the atomizing matrix absorption matrix disclosed herein can adsorb and guide the atomizing matrix through capillary action, thereby avoiding direct contact between the heating body 12 and the atomizing matrix, and further avoiding the atomizing matrix (for example, tobacco oil) from impacting the heating body 12 when the flow rate is too fast, causing it to directly enter the atomizing channel without being atomized.

[0047] In some embodiments, the heating body 12 can be made of, for example, iron-chromium-aluminum or nickel-chromium alloy. The atomized matrix absorption substrate 11 acts as a conductive part of the heating plate 10, and the heating body 12 is attached to the back of the atomized matrix absorption substrate 11 and acts as a heating element.

[0048] As shown in Figures 1 to 3, the electrode 13 may include an electrode 13 (specifically, a positive electrode and a negative electrode), which is electrically connected to the electrode contacts 14 (specifically, a positive electrode contact and a negative electrode contact) of the heating body 12, and is energized with the external battery cell to supply power to the heating body 12. The heating body 12 can be used to heat the atomized matrix in the storage cavity (e.g., the oil storage cavity) that is adsorbed by the atomized matrix absorption matrix 11 and guided to be transferred to the heating body 12, thereby forming an aerosol.

[0049] Optionally, as shown in Figures 2 and 3, two electrode contacts 14 are provided on both sides of the heating body 12, which can be electrode contact sheets extending over the entire length of the atomized matrix absorption matrix 11. A heating wire structure with a planar mesh structure is provided between the two electrode contacts. For example, the heating wires are arranged in an array, and the middle part is diamond-shaped. The heating wire structure can extend over the entire length of the atomized matrix absorption matrix 11. This helps to evenly heat the atomized matrix, thereby promoting the uniformity of the atomized matrix provided by the heating sheet 10. The heating body 12 with a planar mesh structure can be easily fitted on the atomized matrix absorption matrix 11. In addition, when the heating body 12 does not have a mesh structure, the various parts in the heating body 12 are equivalent to a parallel state, which will cause the resistance value to decrease, thereby affecting the heating of the heating body 12. Therefore, the heating body 12 with a mesh structure is conducive to increasing the calorific value per unit area of ​​the heating body 12, thereby promoting the heating and atomization effect of the atomized matrix. In addition, the flat (ie sheet-like) heating body has a greater heating power than the metal-plated one, making the atomization heavier and more complete, and the taste better. In some examples, a smaller grid may be provided in the flat mesh-structured heating body 12, thereby increasing the density of the grid and increasing the heat generation of the single-sided area of ​​the heating body 12. A bending portion 15 (including an electrode contact bending portion and a heating wire bending portion) may be provided at at least one of the two ends of the heating body adjacent to the above-mentioned two sides, which is used to be inserted into the atomized matrix absorption matrix to increase the firmness between the heating body and the atomized matrix absorption matrix.

[0050] In some embodiments, the atomizing matrix absorption matrix can be made of glass or the like. Glass is, for example, quartz glass, high silica glass, etc. Quartz glass includes, but is not limited to, natural quartz glass, synthetic quartz glass, transparent quartz glass, opaque quartz glass, etc. Alternatively, the atomizing matrix absorption matrix can also be made of other materials that can be processed by laser or the like to have a plurality of pores arranged in a preset regular pattern. Compared to the atomizing core made of cotton and ceramic used in the prior art, quartz glass and other materials can be engraved with a plurality of micropores or pores arranged in a preset regular pattern by laser or other processing means. The plurality of micropores or pores are used to adsorb the atomizing matrix by capillary action and are evenly distributed on the surface of a plurality of monomers, thereby promoting the uniformity and efficiency of adsorption and conduction of the atomizing matrix (such as oil smoke), making the formed aerosol softer and having a better taste consistency.

[0051] In some other embodiments, the multiple pores of the atomized matrix absorption matrix can also be formed by sintering. Specifically, the atomized matrix absorption matrix 11 may include multiple monomers, and the multiple monomers are arranged so that multiple pores arranged according to preset rules are formed between each adjacent monomer in the multiple monomers. Compared to obtaining multiple pores directly on the atomized matrix absorption matrix 11 by other physical or chemical methods, the above-mentioned use of the gaps between the monomers as pores can avoid the use of pore-forming agents. On the one hand, it can increase the safety of aerosol generation and avoid the generation of odors. On the other hand, it can enhance the accuracy of the size of multiple pores and the arrangement rules, further avoid the pores generated from being blocked, so that the oil guide channel formed is not obstructed. In this way, the atomized matrix can be adsorbed and conducted more evenly and quickly, promoting the uniformity and consistency of the atomized matrix provided by the heating plate, and improving the efficiency of conduction. Compared to cotton atomizer cores and ceramic atomizer cores, which require 1 to 2 minutes to guide the atomized matrix to the heating wire for heating, the heating plate of the above embodiment can improve the conduction efficiency of the atomized matrix. Specifically, the e-liquid can be conducted to the heating element within 1 to 3 seconds, and water can be conducted to the heating element in less than 1 second. The shape and size of each of the multiple monomers can be consistent or have a certain error range. The shape and size can be set as needed.

[0052] In some embodiments, each of the multiple monomers is spherical. Since the multiple monomers included in the atomizing matrix absorption matrix 11 are relatively small in size, the monomers arranged in a spherical shape are easy to process, which can further reduce manufacturing costs. In addition, it is convenient to form pores with a suitable pore area size between the multiple spherical monomers, so that the multiple pores can adsorb and guide the atomizing matrix through capillary action, thereby avoiding direct contact between the heating body 12 and the atomizing matrix, and further avoiding the atomizing matrix (for example, smoke oil) impacting the heating body 12 when the flow rate is too fast, causing it to directly enter the atomizing channel without atomization. In addition, when the atomizing matrix supplied to the heating plate 10 is exhausted, the atomizing matrix of the multiple pores stored in the heating plate 10 can avoid dry burning of the heating plate and avoid the generation of burnt smell.

[0053] In some embodiments, the diameter of each monomer in the plurality of monomers is in the range of 100 μm to 150 μm. Thus, the plurality of monomers can form a plurality of pores of appropriate size, for example, the pore size of the plurality of pores can be set to the micron level, for example, the pore size of the plurality of pores formed can be, for example, in the range of 40 μm to 50 μm, so that the plurality of pores can achieve the function of guiding and locking oil. Specifically, on the one hand, the smoke oil can be adsorbed and guided through the plurality of pores, and on the other hand, the tension of the atomization matrix such as the smoke oil can be utilized to prevent it from passing through the heating plate 10 into the atomization channel, thereby reducing the risk of leakage. In addition, having a diameter in the range of 100 μm to 150 μm enables each monomer in the plurality of monomers to withstand higher manufacturing temperatures and will not melt.

[0054] In certain embodiments, a plurality of monomers are made of quartz glass. Wherein, quartz glass includes but is not limited to one of natural quartz glass, synthetic quartz glass, transparent quartz glass, opaque quartz glass, etc. A plurality of monomers made of quartz glass can increase the overall strength, damage resistance and temperature resistance of the atomized matrix absorption matrix 11. These properties of quartz glass can make the atomized matrix absorption matrix itself both as a support member of the heater and as a guide member of the atomized matrix, thereby reducing the thickness of the atomized matrix absorption matrix and increasing its service life. In addition, quartz glass also has extremely high safety and is a food grade material. Thus, using quartz glass can increase the safety of the aerosol formed.

[0055] The above-mentioned multiple spherical monomers made of quartz glass and having a diameter within the range of 100 μm to 150 μm can enable the prepared atomized matrix absorption substrate to withstand high temperatures exceeding 1000° C. without melting, thereby increasing the service life of the heating plate.

[0056] In some embodiments, the content of quartz glass in the atomized matrix absorption base 11 is greater than or equal to 90%. Therefore, the use of quartz glass can further increase the service life of the heating plate and improve the safety of the aerosol formed.

[0057] In certain embodiments, the thickness of atomized matrix absorption matrix 11 is less than 2mm, for example, less than 1mm. Alternatively, the thickness of atomized matrix absorption matrix 11 can also be set to between about 1mm to 1.2mm. Atomized matrix absorption matrix of the present disclosure (for example, a plurality of monomers made using quartz glass are arranged to form) can realize that heating sheet has less volume, and does not affect the intensity of atomized matrix absorption matrix.

[0058] In some embodiments, the cross-sectional shape of the atomized matrix absorption matrix 11 can be set to a circular shape, a square shape, etc. When the cross-sectional shape of the atomized matrix absorption matrix 11 is a square shape, the width of the atomized matrix absorption matrix 11 can be set to about 7 mm, and the length of the atomized matrix absorption matrix 11 can be set to about 9 mm. It should be understood that the size of the atomized matrix absorption matrix 11 can be set to other values ​​according to the size of the atomizer.

[0059] In some embodiments, the atomized matrix absorption substrate 11 is formed by sintering a plurality of monomers arranged in an array at a temperature between 800°C and 900°C without the addition of a pore-forming agent. The pore-forming agent includes, but is not limited to, high-temperature decomposable salts such as ammonium carbonate, ammonium bicarbonate, and ammonium chloride, as well as other decomposable compounds such as Si3N4, or inorganic carbon such as coal dust, carbon powder, sawdust, naphthalene, starch, and one of polyvinyl alcohol, urea, methyl methacrylate, polyvinyl chloride, and polystyrene. By sintering at 800°C to 900°C, the plurality of monomers arranged in an array can be combined together, and pores of appropriate size can be formed between adjacent monomers without the need for the pore-forming agent described above. This avoids the pores being clogged by foreign matter generated during the pore-forming agent sintering process, resulting in uneven and inconsistent pores.

[0060] In some embodiments, the heating body 12 can be sintered integrally with multiple monomers. This can simplify the production process and improve economic efficiency. In addition, the sintering process makes it more efficient to attach the heating body 12 to the atomized matrix absorption base 11, and the attachment is more secure and tight, so that even if the heating body 12 is continuously heated during actual use, it is not easy to fall off. In some examples, the heating body and multiple monomers can be pressure-injected into a mold to form a preliminary embryo, and then further fired.

[0061] FIG4 is a perspective view of a heating sheet 10' according to other embodiments of the present disclosure; FIG5 is a perspective view of the heating sheet of FIG4 from another angle; and FIG6 is an exploded view of the heating sheet of FIG4. The features of the heating sheet 10' in FIG4 to FIG6 are substantially the same as those of the heating sheet 10 in FIG1 to FIG3 , the difference being that the planar mesh-shaped heating wire structure in FIG4 to FIG6 extends over a portion of the length of the atomized matrix absorption base 11' and the electrode contact 14' is a partially hollowed-out electrode contact sheet structure.

[0062] Specifically, a planar mesh-like heating wire structure is disposed between the two electrode contacts 14' of the heater 12'. This heating wire structure can extend over a portion of the length of the atomized matrix absorbent substrate 11. A bend 15' (including the electrode contact bend) can be provided at at least one of the two ends of the heater adjacent to the aforementioned two sides. This bend is designed to be inserted into the atomized matrix absorbent substrate to enhance the securement between the heater and the atomized matrix absorbent substrate.

[0063] It should be understood that in addition to the features described above, other features of the heating plate 10' (for example, features of the atomizing matrix absorption base 11', other features of the heating body 12', features of the electrode 13' and the electrode contact 14', etc.) may be the same as the corresponding features of the heating body 10 described in Figures 1 to 3. For the sake of brevity, they will not be described in detail here. According to another aspect of the present disclosure, an atomizing core including the above-mentioned heating plate 10 or 10' is provided. The atomizing core 100 including the heating plate 10 is described in detail below in conjunction with Figures 7 to 9.

[0064] Figure 7 is an exploded view of the atomizer core 100 including the heating plate 10 of Figure 1, and Figure 7 further shows an exploded view of the atomizer 1000 including the atomizer core 100; Figure 8 is a cross-sectional view of the atomizer of Figure 7; Figure 9 is a cross-sectional view of the atomizer of Figure 7 from another angle.

[0065] As shown in FIG. 7 , the atomizer core 100 may include an atomizer core housing 110 , an atomizer seat 120 , and the heating plate 10 described with reference to FIG. 1 to FIG. 3 .

[0066] The atomizer core housing 110 defines an air flow inlet 111 , an air flow outlet 112 , a receiving space 113 between the air flow inlet 111 and the air flow outlet 112 , and an atomizer substrate inlet 114 leading into the receiving space 113 .

[0067] As shown in Figure 7, the atomizing matrix inlet 114 is formed in the atomizing core housing wall and penetrates the atomizing core housing wall, so that the space outside the atomizing core housing and the accommodating space 113 can be connected, so that the atomizing matrix outside the atomizing core housing 110 can enter the interior of the atomizing core housing 110. In Figure 7, an atomizing matrix inlet 114 is shown, that is, a structure with a single oil inlet hole. The atomizing core with an atomizing matrix inlet has the advantage of being more resistant to negative pressure. In some other embodiments, multiple atomizing matrix inlets can also be provided.

[0068] The atomizer seat 120 is disposed within the accommodation space 113 and defines an atomization channel 121 for communicating with the air flow inlet 111 and the air flow outlet 112. As shown in Figure 9, a cavity approximately in the center of the atomizer seat 120 forms an atomization channel 121 for air, steam, and aerosol to flow through. When the atomizer seat 120 is installed in the accommodation space 113 of the atomizer core housing 110, one end of the atomization channel 121 is communicated with the air flow inlet 111 of the atomizer core housing 110, and the other end is communicated with the air flow outlet 112.

[0069] The atomizer seat 120 further defines an opening 122 for communicating the atomizing substrate inlet 114 and the atomizing channel 121. For example, as shown in FIG7 , the atomizer seat 120 is provided with an opening 122 that is at least partially opposite to the atomizing substrate inlet 114 on the atomizing core housing 110, and the heating plate 10 can be disposed in the opening 122, and the opening 122 can be provided with a step for supporting the heating plate 10. Since the opening 122 is formed in the side wall of the atomizer seat 120 and passes through the side wall, the opening 122 is opposite to the atomizing substrate inlet 114 and passes into the atomizing channel 121. Therefore, the atomizing substrate located outside the atomizing core housing 110 can enter the atomizing channel 121 via the atomizing substrate inlet 114 and the opening 122.

[0070] As shown in Figures 7 to 9, the heating plate 10 is arranged in the atomizing seat 120, the heating body faces the atomizing channel, and the surface of the atomizing matrix absorption substrate opposite to the heating body faces the atomizing matrix inlet. Thus, the atomizing matrix entering through the atomizing matrix inlet 114 (and the opening 122) can reach the heating plate 10 and penetrate into the heating body through the multiple pores of the atomizing matrix absorption substrate on the heating plate 10, so as to be heated by the heating body and atomized to form an aerosol.

[0071] In the above embodiment, when the user inhales at the air flow outlet 112, the air flow can reach the air flow outlet 112 from the air flow inlet 111 via the atomizing channel 121 in the atomizing seat 120, thereby forming an air flow path. A part of the air flow path (i.e., atomizing channel 121) forms an atomizing chamber. Wherein, one side of the heating plate 10 is communicated with the atomizing matrix inlet 114 via an opening 122, and its other side is communicated with the air fluid in the atomizing channel 121. The atomizing matrix outside the atomizing core housing 110 penetrates into the atomizing matrix absorption matrix 11 of the heating plate 10 through the atomizing matrix inlet 114 and the opening 122, and then continues to penetrate into the heating body 12 of the heating plate 10, so as to reach the heating body on the first surface 111 of the heating plate, and forms steam after being heated and atomized by the heating body. Steam is entrained in the air flowing through the atomizing channel 121 to form an aerosol for the user to inhale.

[0072] In some embodiments, the heating plate 10 can be arranged longitudinally within the atomizer seat, that is, parallel to the longitudinal extension direction of the atomizer seat 120 or the atomizer core housing 110, so that the heating plate does not block the airflow in the atomization channel 121 from the airflow inlet 111 to the airflow outlet 112. The above embodiment can ensure that the formed aerosol (i.e., smoke) is unobstructed, thereby improving the taste reproduction.

[0073] In some embodiments, the atomizer housing 110 is a hollow structure that provides a mounting space for the atomizer holder 120 and forms an airflow path therein. The atomizer housing 110 can be made of a hard material such as metal, such as copper, iron, or aluminum, to protect the components therein and to separate the storage chamber from the atomization channel 121.

[0074] In some embodiments, the atomizer core 100 further includes a sealing cap 130 disposed at one end of the atomizer core housing 110 where the airflow outlet 112 is located. The sealing cap 130 defines an airflow hole 131, into which the airflow outlet 112 flows, thereby discharging the formed aerosol from the airflow hole 131. The sealing cap not only guides the discharge of the aerosol, but can also be embedded within a guide tube (described in detail below) of the atomizer housing to isolate the guide tube from the environment surrounding the atomizer core, thereby preventing leakage of the formed aerosol.

[0075] In some embodiments, the surface of the atomizing matrix absorption matrix 11 opposite to the heating body 12 is covered on the atomizing matrix inlet 114. Thus, the atomizing matrix absorption matrix 11 can act as a buffer structure between the heating plate 10 and the atomizing matrix, preventing the atomizing matrix (for example, cigarette oil) from impacting the heating plate 10 when the flow rate is too fast, thereby causing it to not be atomized and directly enter the atomization channel, but to be guided to the heating body for heating through multiple pores of the atomizing matrix absorption matrix 11, thereby promoting the uniformity of heating. The atomizing matrix absorption matrix 11 of the heating plate 10 serves as a guiding buffer structure between the atomizing matrix inlet and the heating body, without the need to additionally provide additional atomizing matrix absorption material, thereby reducing the number of components and reducing manufacturing costs.

[0076] In some other embodiments, as shown in Figures 7 and 9, in order to further reduce the risk of leakage, the atomizer core 100 may further include an atomizing matrix absorption material 61. At this time, the heating plate 10 is arranged in the atomizing channel 121 of the atomizing seat, and the atomizing matrix absorption material 61 is embedded in the opening 122 and is located between the atomizing matrix inlet 114 and the heating plate 10. The first side of the atomizing matrix absorption material 61 covers the atomizing matrix inlet 114 from the inside of the atomizing core housing, and the second side opposite to the first side is against the heating plate 10. Thus, a buffer structure can be further provided between the heating plate 10 and the atomizing matrix to prevent 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 directly without atomization. In some examples, the atomizing matrix absorption material 61 may include cotton or woven fabric, including but not limited to sanitary napkins, inert cotton, organic cotton, composite cotton, linen cotton, asbestos, and fiber cotton. Cotton or woven fabrics are made of fibers that absorb and conduct oil, providing a better cushioning effect and preventing excess oil. Furthermore, cotton has evenly distributed pores, allowing for smoother oil conduction.

[0077] In some embodiments, the atomizer core housing 110 defines a notch 115, which extends from one end of the atomizing matrix inlet 114 toward the air flow inlet 111 toward the air flow inlet 111. The above embodiment can allow the airflow from the direction of the air flow inlet 111 to at least partially circulate through the notch, forming an air pressure during the suction process of the atomizer, so that the supply of the atomizing matrix to the heating plate is smoother. In some embodiments, the notch 115 has a width in a direction perpendicular to the extension direction of the notch 115, and the width is set to between 0.05mm and 0.35mm. In this way, the atomizing matrix such as smoke oil can form an oil film between the edges of the notch, thereby avoiding leakage.

[0078] In some embodiments, the size of the opening 122 is smaller than that of the heating plate to prevent the heating plate 10 from falling out of the opening 122. In some other embodiments, the shape and size of the opening 122 can be set so that the heating plate 10 can be placed in the atomization channel 121 through the opening 122. Specifically, for example, the size of the opening 122 can be set to be slightly larger than the size of the heating plate 10, or the size of the opening 122 can be set to be slightly smaller than the size of the heating plate 10 and the heating plate 10 can pass through, for example, at a slight angle, and / or the shape of the opening 122 can be set to match the shape of the heating plate 10.

[0079] The atomizer core 100 may further include an electrode 13. As shown in the embodiment of Figures 1 to 3, the electrode 13 includes two electrodes for contacting the electrode contacts on the heater plate 10. One end of the electrode 13 can extend into the atomizer seat 120 to contact the electrode contacts on the heater plate 10, and the other end at least partially extends from the accommodation space 113 to electrically connect to the electrode member 1800. The materials of the electrodes include, but are not limited to, pure copper, graphite, brass, steel, cast iron, and tungsten alloy.

[0080] According to another aspect of the present disclosure, an atomizer 1000 is provided, comprising: the aforementioned atomizer core 100; and a housing, wherein the atomizer core is disposed within the housing, and a storage cavity for storing an atomized substrate is formed between an inner wall of the housing and an outer wall of the atomizer core. Specifically, for example, as shown in Figures 7 to 9 , the atomizer 1000 may include the aforementioned atomizer core 100 and a housing 1100.

[0081] The atomizer core 100 is disposed within the housing body 1200, and the storage cavity is defined by the space between the inner wall of the housing body 1200, the base 1300, and the outer wall of the atomizer core housing 110. The atomizer substrate in the storage cavity can enter the atomizer core housing through the atomizer substrate inlet 114.

[0082] The atomizer 1000 is also provided with an electrode member 1800 and a magnetic member 1400, and the base 1300 is provided with a through hole, and the electrode 13 of the atomizing core 100 is at least partially provided in the through hole, one end of the electrode 13 is electrically connected to the electrode contact on the heating plate, and the other end is electrically connected to the electrode member 1800. In some embodiments, the material of the electrode member includes but is not limited to pure copper, graphite, brass, steel, cast iron and tungsten alloy. The material of the base 1300 can be composite plastic, etc. In order to prevent the atomized matrix in the storage chamber from leaking from places other than the atomized matrix inlet, a seal 1500 is provided on one side of the base 1300 located in the storage chamber.

[0083] In some embodiments, the housing body 1200 defines a mouthpiece 1600 and a guide tube 1700 extending inward from the mouthpiece 1600. The sealing cap 130 is configured to be embedded within the guide tube 1700 of the atomizer housing body, allowing the aerosol formed by the atomizer core 100 to flow from the sealing cap 130 to the guide tube 1700 and out of the mouthpiece 1600. The sealing cap 130 can separate the guide tube 1700 from the environment surrounding the atomizer core 100, thereby preventing the aerosol formed by the atomizer core from leaking into the environment surrounding the atomizer core. The sealing cap 130 makes the structure of the atomizer 1000 including the atomizer core 100 more compact and provides a better sealing effect. In some embodiments, the base 1300 is configured to accommodate one side of the atomizer core 100 where the airflow inlet is located. The portion of the base opposite the atomizer substrate inlet can be provided with a groove to avoid the atomizer substrate inlet, thereby facilitating effective supply to the atomizer substrate inlet even when the atomizer substrate in the storage chamber is low.
