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 have problems such as uneven heating and easy core burn.

[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 plate. By opening a guide hole for accommodating a first atomized matrix absorption material on a base of the heating plate and fixing a heating body on the surface of the base of the heating plate, the atomized matrix can reach the heating body through the first atomized matrix absorption material in the guide hole for heating, thereby making the heating contact area larger, the heating more uniform, and less likely to cause problems such as core sticking.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] "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.

[0060] "Aerosol" refers to a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium.

[0061] 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.

[0062] In the related art, the heating element in the atomizer core mainly has the following two structures: one is a combination of metal heating wire and cotton core (usually in the form of cotton core wrapped around the heating wire), and the other is a structure in which microporous ceramic and metal heating wire are co-fired to form an integral body. Although the combination of metal heating wire and cotton core has the advantage of good taste restoration, the outer surface of the cotton core is heated by the metal heating wire to atomize the e-liquid, resulting in a small heating contact area. Therefore, the heating element of this structure needs to reach a higher temperature to achieve atomization, which often leads to phenomena such as core sticking. Long-term use is prone to produce a burnt smell and poor taste stability. In addition, compared with the cotton core, the structure of microporous ceramic and metal heating wire as a whole uses a ceramic core. Although it has the advantages of good stability and is not easy to break or stick to the core, it has the problem of poor taste restoration.

[0063] In view of this, the present disclosure proposes a heating plate, which provides a guide hole for accommodating the first atomized matrix absorption material on the base of the heating plate, and fixes the heating body on the surface of the base of the heating plate, so that the atomized matrix can reach the heating body through the first atomized matrix absorption material in the guide hole for heating, thereby making the heating contact area larger, the heating more uniform, and less likely to cause problems such as core sticking. The heating plate according to the present disclosure can achieve the advantages of both the taste restoration of the cotton core and the high stability of the ceramic core. In addition, compared with the combination of metal heating wire and cotton core (which requires manual assembly), the heating plate disclosed in the present disclosure can achieve automated production through jig settings, thereby improving production efficiency.

[0064] 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 substance such as smoke liquid (specifically, smoke oil, etc.) for people to inhale, suck, chew or nasally inhale. 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 that the atomizing core of the present disclosure can also be used in other devices that require atomization of the atomizing matrix, such as medical atomizers, skin care instruments, aromatherapy devices, etc.

[0065] The heating sheet of the present disclosure will be described in detail below with reference to FIG. 1 to FIG. 6 .

[0066] 1 is an exploded view of a heating sheet 100 according to some embodiments of the present disclosure; FIG. 2 is a right side view of the heating sheet 100 of FIG. 1 ; and FIG. 3 is a left side view of the heating sheet 100 of FIG. 1 .

[0067] As shown in FIG. 1 to FIG. 3 , the heating sheet 100 may include a heating sheet base 110 , a heating body 120 , and a first atomized matrix adsorption material 130 .

[0068] The heating plate base 110 includes a first surface 111, a second surface 112, and a guide hole 113 extending from the first surface 111 to the second surface 112. The heating body 120 is disposed on the first surface 111 and at least partially opposite the guide hole 113. The first atomized matrix adsorption material 130 is disposed (e.g., embedded) in the guide hole 113 and abuts against the heating body 120.

[0069] In the above embodiment, the atomized matrix is ​​absorbed and guided by the first atomized matrix absorbing material 130 in the guide hole 113 to reach the heating body 120, where it is heated and atomized. The above embodiment can increase the contact area between the atomized matrix and the heating body 120, making heating more uniform and less likely to cause problems such as core burning.

[0070] In some embodiments, the heater substrate 110 is used to fix components such as the heater 120 and the first atomized matrix absorption material 130. The heater substrate 110 can be made of a high-temperature resistant, hard non-conductive material (e.g., a non-metallic material). In some examples, the heater substrate 110 can be made of hard ceramic, glass, zircon, crystal, etc. The ceramic heater substrate 100 can increase the overall damage resistance of the heater 100. Additionally, the heater substrate 110 can be made of a material suitable for sintering or printing the heater.

[0071] In some embodiments, the cross-sectional shape of the heater substrate 110 can be set to a circular shape, a square shape, or the like. When the cross-sectional shape of the heater substrate 110 is a square shape, the width of the heater substrate 110 can be set to approximately 7 mm, and the length of the heater substrate 110 can be set to approximately 9 mm. Alternatively, the width of the heater substrate 110 can be set to approximately 5 mm, and the length of the heater substrate 110 can be set to approximately 10 mm. In addition, the thickness of the heater substrate 110 can be set to between approximately 1 mm and 1.2 mm. It should be understood that the dimensions of the heater substrate 110 can be set to other values ​​depending on the size of the atomizer.

[0072] In some embodiments, the guide hole 113 defined in the heater substrate 110 may be located in the middle of the heater substrate 110. Alternatively, the guide hole 113 may be located at an end of the heater substrate 110. Furthermore, although only one guide hole is shown in FIG1 , it should be understood that the heater substrate 110 of the present disclosure may also be provided with multiple guide holes.

[0073] In some embodiments, the shape of the cross section of the guide hole 113 can be set to a circular, square, etc. In the case where the shape of the cross section of the guide hole 113 is circular, the diameter of the cross section of the guide hole 113 can be set to about 4.5 mm, which is particularly suitable for a heating plate substrate 110 with a width of about 7 mm and a length of about 9 mm. Alternatively, in the case where the shape of the cross section of the guide hole 113 is square, the width of the cross section of the guide hole 113 can be set to about 2.5 mm, and the length of the cross section of the guide hole 113 can be set to about 4 mm, which is particularly suitable for a heating plate substrate 110 with a width of about 5 mm and a length of about 10 mm. It is understood that the size of the guide hole 113 can be set to other values ​​as needed. The size of the guide hole 113 cannot be set too large to prevent too much atomized matrix from entering from the guide hole 113, causing the heating body 120 to be unable to evenly atomize it, thereby causing problems such as core burn. In addition, the size of the guide hole 113 cannot be set too small to prevent too little atomized substrate from entering through the guide hole 113 and causing the heating body 120 to dry-burn.

[0074] In some embodiments, as shown in Figures 1 to 3, the opening of the guide hole 113 on the first surface 111 is completely covered by the heater 120. This allows for more uniform heating of the atomized substrate and prevents the atomized substrate from entering the atomization channel without being atomized. Alternatively, the opening of the guide hole 113 on the first surface 111 is partially covered by the heater 120.

[0075] In some embodiments, the heating body 120 has a planar mesh structure, as shown in Figure 3. The heating body 120 with a planar mesh structure can be easily attached to the heating sheet substrate 110. In addition, when the heating body 120 does not have a mesh structure, the various parts in the heating body 120 are equivalent to a parallel state, which will cause the resistance value to decrease, thereby affecting the heating of the heating body 120. Therefore, the heating body 120 with a mesh structure is conducive to increasing the calorific value per unit area of ​​the heating body 120, thereby promoting the heating and atomization effect of the atomized matrix. In some examples, a smaller grid can be provided in the heating body 120 with a planar mesh structure, thereby increasing the density of the grid and increasing the calorific value of the single-sided area of ​​the heating body 120.

[0076] In some embodiments, the heater 120 can be fixed to the first surface 111 by a printing process (e.g., a thick film printing process) or a sintering process (a high-temperature sintering process). Compared to processes such as welding, the printing process and the sintering process make it more efficient to attach the heater 120 to the first surface 111 of the heater substrate 110, and the attachment is more secure and tight, so that the heater 120 is not likely to fall off even when it is continuously heated in actual use. In some examples, the heater 120 can be made of a conductive material such as metal (e.g., nickel-chromium alloy).

[0077] In some embodiments, at least one of the surface of the heater 120 opposite the first surface 111 and the first surface 111 of the heater base is flat. This facilitates printing of the conductive paste when attaching the heater 120 using a printing process, thereby improving the production efficiency of the heater 100.

[0078] In some embodiments, the first atomizing matrix absorption material 130 may include cotton. Cotton includes, but is not limited to, sanitary napkins, inert cotton, organic cotton, composite cotton, linen cotton, asbestos, and fiber cotton. The first atomizing matrix absorption material 130 may be provided with a buffer structure between the heater 120 and the atomizing matrix to prevent direct contact between the heater 120 and the atomizing matrix, thereby preventing the atomized matrix (e.g., tobacco oil) from impacting the heater when the flow rate is too fast, causing it to enter the atomization channel without atomization. Furthermore, cotton is composed of fibers, which can absorb and guide oil, thereby better achieving the effect of buffering and avoiding excessive oil. Furthermore, cotton has the characteristic of evenly distributed pores, which makes the oil conduction smoother. The heating plate 100 of the above embodiment can make the mouthfeel of the aerosol formed by the atomization of the atomized matrix similar to the structure of a metal heating wire plus a cotton wick in the related art. At the same time, due to the arrangement of the heater 120 disclosed in the present invention, the heat generation is not excessively concentrated, which would cause the first atomizing matrix absorption material 130 to burn, thereby maintaining the mouthfeel of the aerosol for a longer period of time.

[0079] In some embodiments, the shape and size of the first atomized matrix absorption material can match the shape and size of the guide hole. Specifically, the shape of the cross section of the first atomized matrix absorption material can be the same as the shape of the cross section of the guide hole (as shown in Figures 1 and 4), or the shape of the cross section of the first atomized matrix absorption material can also be different from the shape of the cross section of the guide hole. For example, the cross section of the guide hole is square, and the shape of the cross section of the first atomized matrix absorption material is a circle inscribed in the square, as shown in Figures 21 and 22. In addition, the size of the cross section of the first atomized matrix absorption material can be slightly smaller than the size of the cross section of the guide hole, or the size of the cross section of the first atomized matrix absorption material can be greater than or equal to the size of the cross section of the guide hole, that is, it is set so that the first atomized matrix absorption material can be embedded in the guide hole and have an interference fit with the guide hole.

[0080] In some embodiments, the heating plate 100 may include a plurality of electrode contacts 140 disposed at at least one end of the heating element 120. For example, as shown in Figures 1 to 3, the heating plate 100 includes two electrode contacts 140 disposed at the left and right ends of the heating element 120, respectively. Alternatively, the two electrode contacts 140 may be disposed at the upper and lower ends of the heating element 120, respectively, as shown in Figure 3. The electrode contacts 140 may be connected to an external power source to provide power to the heating element 120.

[0081] In some embodiments, the heating sheet 100 using the first atomizing matrix absorption material including cotton can generate an aerosol with a high degree of taste restoration and can be applied to disposable electronic cigarettes, etc.

[0082] Figure 4 is a perspective view of a heating plate 200 according to other embodiments of the present disclosure; Figure 5 is a perspective view of the heating plate 200 in Figure 4 from another angle; and Figure 6 is a cross-sectional view of the heating plate 200 in Figure 4 along the AA section line. The features of the heating plate 200 in Figures 4 to 6 are substantially the same as those of the heating plate 100 in Figures 1 to 3 . The difference between the two is that the first atomized substrate absorption material 230 in the heating plate 200 in Figures 4 to 6 can be a block-shaped structure with multiple micropores, such as porous ceramic, porous glass, etc. The multiple micropores can be formed by laser or chemical etching. The multiple micropores are used to absorb the atomized substrate through capillary action. This allows the atomized substrate to be absorbed into the micropores of the porous ceramic through the capillary action of the porous ceramic, for example, and then transferred to the heating element through the porous ceramic for heating. The above-described embodiment not only controls or increases the amount of atomized substrate, such as tobacco oil, absorbed, but also makes the oil intake more uniform, thereby promoting a softer aerosol and a more consistent taste. Furthermore, when the atomized substrate supplied to the heater plate 200 is depleted, the atomized substrate stored in the micropores of the heater plate 200 prevents the heater plate from burning dry and thus avoids the generation of a burnt smell. In some examples, the apertures of the multiple micropores can be set to micrometers. This can utilize the tension of the atomized substrate, such as tobacco oil, to prevent it from passing through the heater plate 200 and entering the atomization channel, thereby reducing the risk of leakage.

[0083] In some embodiments, referring to FIG6 , the first atomized matrix adsorption material 230 defines a third surface 231 proximate to the second surface 212 of the heater substrate 210. The third surface 231 is spaced apart from the second surface 212 of the heater substrate 210 by a predetermined distance in a direction perpendicular to the second surface 212. In other words, if the size of the guide hole 213 is constant, the thickness of the first atomized matrix adsorption material 230 can be adjusted to control the amount of atomized matrix adsorbed, thereby adapting to different types of atomized matrix.

[0084] In some embodiments, the preset distance can be set in association with the type of atomized matrix. For example, if the atomized matrix has high viscosity and slow permeation, the preset distance can be increased, i.e., the thickness of the first atomized matrix absorbing material 230 can be reduced, so that the heating element can receive more atomized matrix to prevent the core from becoming sticky. If the atomized matrix has low viscosity and fast permeation, the preset distance can be reduced, i.e., the thickness of the first atomized matrix absorbing material 230 can be increased, thereby reducing the amount of atomized matrix supplied to the heating element.

[0085] In the heating plate 200, the width of the heating plate base 210 can be set to about 5 mm, and the length of the heating plate base 210 can be set to about 10 mm. The width of the cross section of the guide hole 213 can be set to about 2.5 mm, and the length of the cross section of the guide hole 213 can be set to about 4 mm. In this case, the thickness of the first atomized matrix adsorption material 230 can be set to between about 0.3 mm and 0.6 mm.

[0086] In some embodiments, the heating plate 200 may further include a second atomizing matrix absorbing material 250 disposed within the guide hole 213 and abutting against the third surface of the first atomizing matrix absorbing material 230. The second atomizing matrix absorbing material 250 comprises cotton, wherein the cotton includes but is not limited to sanitary napkins, inert cotton, organic cotton, composite cotton, linen cotton, asbestos, and fiber cotton. The second atomizing matrix absorbing material 250 can further strengthen the buffer between the heating body 120 and the atomizing matrix, thereby preventing the atomizing matrix (e.g., tobacco oil) from impacting the heating body when the flow rate is too fast, causing it to directly enter the atomization channel without being atomized.

[0087] 5 , the heating plate 200 may have two electrode contacts 240 disposed at the upper and lower ends of the heating body, respectively. The two electrode contacts 240 are disposed at the upper and lower ends of the heating body 220, respectively.

[0088] In one or more of the above embodiments, the heating plate 200 may be manufactured by the following steps: sintering the heating body 220 and the first atomized matrix adsorption material 230 ; and then firing the heating plate base 210 around the first atomized matrix adsorption material 230 using a jig.

[0089] It should be understood that in addition to the features described above, other features of the heating plate 200 (for example, other features of the heating plate substrate 210, other features of the heating body 220, features of the first surface 211 and the second surface 212, etc.) may be the same as the corresponding features of the heating body 100 described in Figures 1 to 3. For the sake of brevity, they will not be described in detail here.

[0090] In some embodiments, the heating sheet 200 using the first atomized matrix absorption material having a block structure with a plurality of micropores has a long service life and can therefore be applied to rechargeable electronic cigarettes and the like.

[0091] According to another aspect of the present disclosure, an atomizer core is provided that includes the heating plate 100 or 200. This atomizer core is described in detail below with reference to Figures 7 to 19.

[0092] FIG7 is a perspective view of the atomizer core 1000 including the heating plate 100 of FIG1 ; FIG8 is an exploded view of the atomizer core 1000 of FIG7 ; FIG10 is a cross-sectional view of the atomizer core 1000 in FIG7 , wherein the cross-sectional direction passes through the atomizer substrate inlet in FIG7 ; FIG9 is a cross-sectional view of the atomizer core 1000 in FIG7 , wherein the cross-sectional direction is orthogonal to the cross-sectional direction of FIG10 ; FIG11 is a perspective view of the atomizer seat 1200 in the atomizer core 1000 of FIG7 ; FIG12 7 ; FIG13 is a perspective view of the atomizer seat 1200 and the heating plate 100 in the atomizer core 1000 of FIG7 , wherein the atomizer seat 1200 is cut open; FIG14 is a perspective view of the atomizer seat 1200 and the heating plate 100 in the atomizer core 1000 of FIG7 , wherein the atomizer seat 1200 is cut open and the atomizer seat 1200 and the heating plate 100 are assembled together.

[0093] As shown in FIG7 to FIG14 , the atomizer core 1000 may include an atomizer core housing 1100 , an atomizer seat 1200 , and the heating plate 100 described with reference to FIG1 to FIG3 .

[0094] The atomizing core housing 1100 includes an air flow inlet 1110, an air flow outlet 1120, a receiving space 1130 between the air flow inlet 1110 and the air flow outlet 1120, and an atomizing matrix inlet 1140 that is connected to the receiving space 1130. As shown in Figure 7, the atomizing matrix inlet 1140 is formed in the atomizing core housing wall and runs through the atomizing core housing wall, so that the space outside the atomizing core housing and the receiving space 1130 can be connected, so that the atomizing matrix outside the atomizing core housing 1100 can enter the interior of the atomizing core housing 1100. In Figure 7, an atomizing matrix inlet 1140 is shown, which is a structure of a single oil inlet. 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.

[0095] The atomizer seat 1200 is arranged in the accommodating space 1130 and defines an atomizing channel 1210 for communicating with the air flow inlet 1110 and the air flow outlet 1120 and an opening 1220 for communicating with the atomizing matrix inlet 1140 and the atomizing channel 1210. As shown in Figures 10 and 11, the cavity roughly in the center of the atomizer seat 1200 forms the atomizing channel 1210. When the atomizer seat 1200 is installed in the accommodating space 1130 of the atomizer core housing 1100, one end of the atomizing channel 1210 is communicated with the air flow inlet 1110 of the atomizer core housing 1100, and the other end is communicated with the air flow outlet 1120. In addition, as shown in Figure 11, the opening 1220 is formed in the side wall of the atomizer seat 1200 and runs through the side wall. The opening 1220 is opposite to the atomizing matrix inlet 1140 and passes into the atomizing channel 1210. Thus, the atomizing substrate outside the atomizing core housing 1100 can enter the atomizing channel 1210 through the atomizing substrate inlet 1140 and the opening 1220 .

[0096] The heating plate 100 is disposed within the atomizing seat 1200, with the first surface 111 of the heating plate 100 facing the atomizing channel 1210 and the second surface 112 of the heating plate 100 facing the atomizing substrate inlet 1140. Thus, the atomizing substrate entering through the atomizing substrate inlet 1140 (and the opening 1220) can reach the guide hole on the second surface 112 of the heating plate 100, and penetrate into the heating body through the first atomizing substrate absorbing material 130 in the guide hole, so as to be heated by the heating body and atomized to form an aerosol.

[0097] In the above embodiment, when the user inhales at the air flow outlet 1120, the air flow can reach the air flow outlet 1120 from the air flow inlet 1110 via the atomizing channel 1210 in the atomizing seat 1200, thereby forming an air flow path. A part of the air flow path (i.e., atomizing channel 1210) forms an atomizing chamber. Wherein, one side of the heating plate 100 is communicated with the atomizing matrix inlet 1140 via an opening 1220, and its other side is communicated with the air fluid in the atomizing channel 1210. The atomizing matrix outside the atomizing core housing penetrates into the second surface 112 of the heating plate 100 through the atomizing matrix inlet 1140 and the opening 1220, and then continues to penetrate into the first atomizing matrix absorption material 130 inside the guide hole of the heating plate 100, so as to reach the heating body on the first surface 111 of the heating plate, and steam is formed after being heated and atomized by the heating body. Steam is entrained in the air flowing through the atomizing channel 1210 to form an aerosol for the user to inhale.

[0098] In some embodiments, as shown in Figures 9 and 10, the heating plate 100 can be arranged longitudinally within the atomizer seat, that is, parallel to the longitudinal extension direction of the atomizer seat 1200 or the atomizer core housing 1100, so that the heating plate does not block the airflow within the atomization channel 1210 from the airflow inlet 1110 to the airflow outlet 1120. The above embodiment can ensure that the formed aerosol (i.e., smoke) is unobstructed, thereby improving the taste reproduction.

[0099] In some embodiments, the atomizer housing 1100 is a hollow structure that provides a mounting space for the atomizer holder 1200 and forms an airflow path therein. The atomizer housing 1100 can be made of a metal, such as a hard material such as copper, iron, or aluminum, to protect the components therein and to separate the storage chamber from the atomization channel 1210.

[0100] In some embodiments, an air flow conduit 1160 extends from the air flow outlet 1120 of the atomizer core housing 1100 to guide the aerosol formed in the atomizer core out.

[0101] In some embodiments, as shown in Figures 7 and 8, the atomizer core housing 1100 may include a notch 1150, which extends from one end of the atomized substrate inlet 1140 that faces the air flow inlet 1110 toward the air flow inlet 1110. This embodiment allows at least a portion of the air flow from the air flow inlet 1110 to flow through the notch, thereby generating air pressure during the atomizer's inhalation process, thereby smoothing the supply of atomized substrate to the heating plate.

[0102] In some embodiments, the slot 1150 has a width perpendicular to the slot's extension direction, which is set to be between about 0.15 mm and 0.20 mm. This allows atomized substrates, such as tobacco oil, to form an oil film between the edges of the slot, thereby preventing leakage.

[0103] In some embodiments, the atomizer seat 1200 is used to provide an installation space for the heating plate 100 and to set an atomizer channel 1210 for air, steam and aerosol to flow through.

[0104] In some embodiments, as shown in Figures 11 to 14, a limiting groove 1211 and a limiting portion 1212 located on the bottom wall of the limiting groove 1211 are provided in the atomizing channel 1210, and the heating plate 100 is inserted into the limiting groove 1211 and abuts against the limiting portion 1212 to at least partially oppose the opening 1220. In this way, the atomized matrix entering through the atomizing matrix inlet 1140 and the opening 1220 can reach the guide hole on the second surface 112 of the heating plate 100, and is guided to the heating body on the first surface 111 of the heating plate 100 via the first atomizing matrix absorption material 130 in the guide hole, so as to be heated by the heating body and atomized to form an aerosol. In the above embodiment, as shown in Figure 12, the heating plate 100 is inserted into the limiting groove 1211 from one end of the atomizing seat close to the airflow outlet 1120, that is, from the left side of Figure 12. 13 and 14 , a stopper 1212 is provided on the bottom wall of the stopper groove 1211 (specifically, the stopper 1212 may be a protrusion protruding from the bottom wall of the stopper groove 1211). The heater plate 100 is inserted into the stopper groove 1211 and positioned at the stopper 1212, at least partially opposite the opening 1220. In some embodiments, the size of the opening 1220 is smaller than that of the heater plate to prevent the heater plate 100 from falling out of the opening 1220. In other embodiments, the shape and size of the opening 1220 may be configured to allow the heater plate 100 to pass through the opening 1220 and be positioned within the atomization channel 1210. Specifically, for example, the size of the opening 1220 may be configured to be slightly larger than the size of the heater plate 100, or the size of the opening 1220 may be configured to allow the heater plate 100 to pass through, for example, at a slight angle, and / or the shape of the opening 1220 may be configured to match the shape of the heater plate 100.

[0105] As shown in Figures 8 and 10, in order to further reduce the risk of leakage, the atomizer core 1000 may further include a third atomization matrix absorption material 1300. The third atomization matrix absorption material 1300 is embedded in the opening 1220 and is located between the atomization matrix inlet 1140 and the heating plate 100. The first side of the third atomization matrix absorption material 1300 covers the atomization matrix inlet 1140 from the inside of the atomizer core housing, and the second side opposite to the first side is abutted against the heating plate 100, specifically against the second surface 112 of the heating plate 100. Thus, a buffer structure can be provided between the heating plate 100 and the atomization matrix to prevent the atomization matrix (e.g., smoke oil) from impacting the heating plate when the flow rate is too fast, thereby causing it to enter the atomization channel directly without atomization. In some examples, the third atomization matrix absorption material 1300 may include cotton, which includes but is not limited to sanitary napkins, inert cotton, organic cotton, composite cotton, linen cotton, asbestos, and fiber cotton. Cotton is made of fibers that absorb and guide oil, providing a better cushioning effect and preventing excess oil. Furthermore, cotton has evenly distributed pores, allowing for smoother oil transfer.

[0106] The atomizer core 1000 may further include electrodes 1400 (in the embodiment shown in Figures 7 to 11, two electrodes are included) for contacting the electrode contacts on the heater plate 100. The electrodes 1400 may extend into the atomizer base 1200 to contact the electrode contacts on the heater plate 100. Materials for the electrodes include, but are not limited to, pure copper, graphite, brass, steel, cast iron, and tungsten alloy.

[0107] As shown in Figures 13 and 14, the atomizer seat 1200 may further define a plurality of first limiting channels 1230 surrounding the limiting portion 1212, with the plurality of electrodes respectively inserted into one of the plurality of first limiting channels 1230. The shape and size of the first limiting channels 1230 may be adapted to the electrode 1400 to ensure the stability of the position of the electrode 1400 relative to the atomizer seat 1200 when inserted into the atomizer seat 1200.

[0108] In one or more of the above-described embodiments, the assembly of some components of the atomizer 1000 may be as follows: the electrode 1400 is pre-attached to the electrode contact of the heating plate 100; the heating plate 100 with the electrode 1400 attached is inserted into the limiting groove 1211 from the end of the atomizer base near the airflow outlet 1120 (during the insertion of the heating plate, the electrode is also inserted into and passes through the first limiting channel 1230 around the limiting portion 1212) until the heating plate abuts against the limiting portion 1212, thereby positioning the heating plate 100 at least partially opposite the opening 1220; and the third atomized matrix adsorption material 1300 is inserted from the direction of the opening 1220. Alternatively, the atomized matrix adsorption material 130 can be assembled separately from the heating plate base with the heater and electrode. That is, the heating plate base with the heating body and the electrode is inserted into the limiting groove 1211 of the atomizing channel 1210 until the heating plate rests against the limiting portion 1212 protruding on the bottom wall of the limiting groove 1211, and then the first atomizing matrix absorption material 130 (placed in the guide hole of the heating plate base) and the third atomizing matrix absorption material 1300 (placed in the opening of the atomizing seat) are placed in sequence from the direction of the opening 1220.

[0109] It should be understood that although the atomizer core 1000 includes the heating plate 100 described with reference to FIG. 1 to FIG. 3 , the atomizer core 1000 may alternatively include the heating plate 200 described with reference to FIG. 4 to FIG. 6 .

[0110] Figures 15 to 19 illustrate atomizer cores 2000 according to other embodiments of the present disclosure. The features of the atomizer cores 2000 in Figures 15 to 19 are substantially the same as those of the atomizer core 1000 in Figures 7 to 14 , with the difference being that the heating plate of the atomizer core 2000 in Figures 15 to 19 is the heating plate 200 described with reference to Figures 4 to 6 , and the heating plate is disposed within the opening 2220 .

[0111] Specifically, as shown in Figures 15 to 19, a fixed cover 2500 is provided between the atomizer core housing 2100 and the atomizer seat 2200, wherein the fixed cover 2500 is used to confine the heating plate 200 within the opening 2220 and includes a window 2510, which is opposite to and connected to the opening 2220 and the atomizer substrate inlet 2140. The fixed cover 2500 is arranged in the accommodating space 2130 of the atomizer core housing 2100 and is fixed relative to the atomizer seat 2200. Thus, it is easy to confine the heating plate within the opening and does not affect the transfer of the atomizer substrate from the atomizer substrate inlet 2140 to the heating plate. Furthermore, the size of the window 2510 along the longitudinal direction of the atomizer core 2000 can be smaller than the size of the heating plate 2000, thereby ensuring that the heating plate 200 is confined within the opening 2220 and will not fall out of the window 2510.

[0112] A third atomized matrix adsorbing material 2300 is disposed between the fixed cover 2500 and the atomizing seat 2200. The third atomized matrix adsorbing material 2300 has a first side surface and a second side surface opposite the first side surface. The first side surface covers the window 2510 from the inside of the fixed cover 2500, and the second side surface at least partially abuts the heating plate 200. This facilitates confinement of the third atomized matrix adsorbing material 2300 and the heating plate 200 within the opening 2220. Furthermore, the dimension of the window 2510 along the longitudinal direction of the atomizing core 2000 can be smaller than the dimension of the third atomized matrix adsorbing material 2300, thereby ensuring that the third atomized matrix adsorbing material 2300 is confined and prevented from escaping from the window 2510.

[0113] It should be understood that other features of the third atomized matrix adsorption material 2300 are the same as those of the third atomized matrix adsorption material of Figures 7 to 14 and will not be described in detail here.

[0114] The atomizer core 2000 may further include an electrode 2400 (in the embodiment shown in FIG. 15 to FIG. 19 , including a first electrode 2410 and a second electrode 2420 ) for contacting the electrode contacts on the heating plate 200 .

[0115] As shown in Figure 18, in order to ensure that the electrode contacts the electrode contact during assembly, the atomizer seat 2200 may also define multiple second limiting channels 2230 located at different ends of the atomizer seat. Multiple electrodes are respectively inserted into a second limiting channel in the multiple second limiting channels 2230 to contact an electrode contact in the multiple electrode contacts. Specifically, as shown in Figures 18 to 19, the multiple second limiting channels 2230 may include a second limiting channel 2231 on the upper side and a second limiting channel 2232 on the lower side. The second limiting channel 2231 on the upper side extends from one end of the atomizer seat 2200 near the air flow outlet 2120 to the other end near the air flow inlet 2110, while the second limiting channel 2232 on the lower side is located at the other end of the atomizer seat 2200 near the air flow inlet 2110. The first electrode 2410 and the second electrode 2420 are respectively inserted into the second limiting channel 2231 on the upper side and the second limiting channel 2232 on the lower side. The shape and size of the second limiting channel can be adapted to the electrode to ensure the stability of the position of the electrode inserted into the atomizer seat 2200 relative to the atomizer seat 2200 .

[0116] In some embodiments, each electrode in the plurality of electrodes defines a first portion located within the corresponding second limiting channel and a second portion extending from the limiting channel into an opening connected to the limiting channel. As shown in Figure 18, the first electrode 2410 defines a first portion 2411 located within the second limiting channel 2231 on the upper side and a second portion 2412 extending outwardly from the first portion 2411 (i.e., extending from the second limiting channel 2231 on the upper side into the opening 2220 connected to the limiting channel so as to contact the electrode contacts on the heating plate in the opening). As shown in Figure 18, the second electrode 2420 defines a first portion 2421 located within the second limiting channel 2232 on the lower side and a second portion 2422 extending outwardly from the first portion 2421, so that the electrode forms an L-shape. This shape facilitates the electrode extending from the second limiting channel 2232 on the lower side into the opening 2220 connected to the limiting channel so as to contact the electrode contacts on the heating plate in the opening.

[0117] In one or more of the above-mentioned embodiments, the assembly method of some components of the atomizer may be as follows: insert the first electrode 2410 and the second electrode 2420 into the second limiting channel 2231 on the upper side and the second limiting channel 2232 on the lower side from the two ends of the atomizer seat 2200 respectively; install the heating plate 200 into the opening 2220 of the atomizer seat 2200; insert the third atomization matrix absorption material 2300 from the direction of the opening 2220; install the fixing cover 2500 on the atomizer seat 2200 to maintain the position of the third atomization matrix absorption material 2300 and the heating plate 200.

[0118] It should be understood that, in addition to the features described above, other features of the atomizer core 2000 (for example, other features of the atomizer core housing 2100 , other features of the atomizer seat 2200 , etc.) may be the same as the corresponding features of the atomizer core 1000 described in FIG. 7 to FIG. 14 , and for the sake of brevity, they will not be described in detail here.

[0119] It should be understood that although the atomizer core 2000 includes the heating plate 200 described with reference to FIG. 4 to FIG. 6 , the atomizer core 2000 may alternatively include the heating plate 100 described with reference to FIG. 1 to FIG. 3 .

[0120] Figures 20 to 23 illustrate atomizer cores 5000 according to other embodiments of the present disclosure. The features of the atomizer cores 5000 in Figures 20 to 23 are substantially the same as those of the atomizer core 1000 in Figures 7 to 14 , with the difference being that the heating plate in the atomizer core 5000 in Figures 20 to 23 is a heating plate 300 and that the airflow outlet of the atomizer core housing 5100 of the atomizer core 5000 is not provided with an airflow duct but with a sealing cap 5151.

[0121] Specifically, as shown in Figures 21 and 22, the cross-sectional shape of the first atomized matrix adsorption material 330 differs from the cross-sectional shape of the guide hole 313. The guide hole 313 has a square cross-sectional shape, while the cross-sectional shape of the first atomized matrix adsorption material 330 is a circle inscribed within the square. Furthermore, the cross-sectional dimensions of the first atomized matrix adsorption material 330 are set so that the first atomized matrix adsorption material can be embedded in the guide hole, thereby achieving an interference fit with the guide hole.

[0122] As shown in Figures 20 to 23, the atomizer core 5000 further includes a sealing cap 5150 disposed at one end of the atomizer core housing 5100 where the airflow outlet 5120 is located. The sealing cap 5150 includes an airflow hole 5151, into which the airflow outlet 5120 flows, so that the formed aerosol is discharged from the airflow hole 5151. The sealing cap not only serves to guide the discharge of the aerosol, but can also be embedded in a guide tube (described in detail below with reference to Figure 27) of the atomizer housing body to isolate the guide tube from the environment surrounding the atomizer core and prevent leakage of the formed aerosol. Compared with the atomizer core 1000 of Figures 7 to 14 and the atomizer core 2000 of Figures 15 to 19, the sealing cap 5150 integrates the airflow duct extending from the airflow outlet of the atomizer core shell and the first sealing member (as shown in Figure 25, the airflow duct 1160 and the first sealing member 3400), so that the structure of the atomizer including the atomizer core 5000 is more compact and the sealing effect is better.

[0123] It should be understood that, in addition to the features described above, other features of the atomizer core 5000 (for example, other features of the atomizer core housing 5100 , features of the air flow inlet 5110 , features of the third atomization matrix absorption material 5300 , and other features of the atomizer seat 5200 , etc.) may be the same as the corresponding features of the atomizer core 1000 described in FIG. 7 to FIG. 14 , and for the sake of brevity, they will not be described in detail here.

[0124] It should be understood that although the atomizer core 5000 includes the heating plate 300, the atomizer core 2000 may alternatively include the heating plate 100 described with reference to Figures 1 to 3 or the heating plate 200 described with reference to Figures 4 to 6.

[0125] According to another aspect of the present disclosure, an atomizer is provided, comprising: the atomizer core 1000, 2000, or 5000 according to the above-mentioned embodiment; and a shell, wherein the atomizer core is arranged in the shell, and a storage cavity for storing the atomized matrix is ​​formed between the inner wall of the shell and the outer wall of the atomizer core.

[0126] Specifically, for example, as shown in Figures 24 and 25 , the atomizer 3000 may include the atomizer core 1000 and a housing 3100 . Furthermore, as shown in Figure 26 , the atomizer 4000 may include the atomizer core 2000 and a housing 4100 . As shown in Figures 27 and 28 , the atomizer 6000 may include the atomizer core 5000 and a housing 6100 .

[0127] As shown in FIG21 , the housing 3100 of the atomizer may include a housing body 3200 and a base 3300, wherein the atomizer core 1000 is disposed within the housing body 3200, and a storage cavity is defined by the space between the inner wall of the housing body 3200, the base 3300, and the outer wall of the atomizer core housing 1100 of the atomizer core. The atomized substrate in the storage cavity can enter the atomizer core housing via an atomized substrate inlet.

[0128] The atomizer 3000 may also include a first seal 3400, a second seal 3500, an annular seal ring 3600, an oil filling plug 3700, an electrode member 3800, and a bottom cover 3900. As shown in Figure 21, a suction nozzle portion is provided on the shell body 3200, and a suction nozzle opening is provided in the suction nozzle portion. The shell body 3200 defines a guide tube extending inward from the suction nozzle opening. One end of the atomizing core 1000 is connected to the guide tube, and the other end thereof is inserted into the base 3300. In order to prevent the atomized matrix in the storage chamber from leaking from places other than the atomized matrix inlet, a first seal 3400 is provided between the guide tube and the atomizing core 1000. A second seal 3500 is provided on one side of the base 3300 located in the storage chamber, and an annular seal ring 3600 is provided on the periphery of the base 3300. The bottom cover 3900 is disposed at one end of the housing body 3200 away from the suction nozzle opening and is detachably connected to the housing body 3200 to confine the various components within the housing body 3200 within the housing body 3200 .

[0129] The atomizer 3000 is further provided with an electrode member 3800 , and the second sealing member 3500 and the base 3300 are provided with a through hole. The atomizer core 1000 is at least partially disposed in the through hole, and the electrode of the atomizer core 1000 is electrically connected to the electrode member 3800 .

[0130] The base 3300 is also provided with a second through-hole, which communicates with the storage chamber. An oil filling plug 3700 is disposed within the second through-hole to prevent oil leakage. At this point, the atomized matrix is ​​first injected into the storage chamber through the second through-hole, and then the oil filling plug 3700 is inserted into the second through-hole to seal the storage chamber. The base 3300 and the bottom cover 3900 are correspondingly provided with air inlet holes, which connect the external space to the airflow inlet of the atomizer core 1000.

[0131] In some embodiments, the material of the electrode includes, but is not limited to, pure copper, graphite, brass, steel, cast iron, and tungsten alloy. The material of each sealing component includes, but is not limited to, rubber, silicone, composite plastic, etc. The material of the base includes, but is not limited to, composite plastic, etc.

[0132] As shown in FIG22 , the housing 4100 of the atomizer may include a housing body 4200 and a base 4300, wherein the atomizer core is disposed within the housing body 4200, and a storage cavity is defined by the space between the inner wall of the housing body 4200, the base 4300, and the outer wall of the atomizer core housing 2100 of the atomizer core. The atomized substrate in the storage cavity may enter the atomizer core housing via an atomized substrate inlet.

[0133] The atomizer 4000 may further include a first sealing member 4400, a second sealing member 4500, an annular sealing ring 4600, an oil filling plug 4700, an electrode member 4800, and a bottom cover 4900. It should be understood that the features of the first sealing member 4400, the second sealing member 4500, the annular sealing ring 4600, the oil filling plug 4700, the electrode member 4800, and the bottom cover 4900 of the atomizer 4000 are the same as those of the corresponding components of the atomizer 3000 and, for the sake of brevity, will not be described in detail herein.

[0134] As shown in Figures 27 and 28, the housing 6100 of the atomizer may include a housing body 6200 and a base 6300, wherein the atomizer core is disposed within the housing body 6200, and a storage cavity is defined by the space between the inner wall of the housing body 6200, the base 6300, and the outer wall of the atomizer core housing 5100 of the atomizer core. The atomized substrate in the storage cavity can enter the atomizer core housing via the atomized substrate inlet 5140.

[0135] In some embodiments, the housing body 6200 includes a mouthpiece 6210 and a guide tube 6220 extending inward from the mouthpiece 6210, wherein a sealing cap 5150 is sealingly embedded in the guide tube 6220 to connect the guide tube 6220 with the airflow hole 5151. The sealing cap is used to be embedded in the guide tube 6220 of the housing body of the atomizer, so that the aerosol formed by the atomizer core 5000 flows from the airflow hole 5151 to the guide tube 6220 and out of the mouthpiece 6210. The sealing cap 5150 can isolate the guide tube 6220 from the environment surrounding the atomizer core 5000, thereby preventing the aerosol formed by the atomizer core from leaking into the environment surrounding the atomizer core. Compared with the atomizer core 1000 of Figures 7 to 14 and the atomizer core 2000 of Figures 15 to 19, the sealing cap 5150 integrates the airflow duct extending from the airflow outlet of the atomizer core shell and the first sealing member (as shown in Figure 25, the airflow duct 1160 and the first sealing member 3400), so that the structure of the atomizer including the atomizer core 5000 is more compact and the sealing effect is better.

[0136] In some embodiments, the base 6300 is used to accommodate the side of the air flow inlet of the atomizing core 5000. The portion of the base opposite to the atomizing matrix inlet is provided with a groove to avoid the atomizing matrix inlet, thereby helping to achieve effective supply to the atomizing matrix inlet when there is less atomizing matrix in the storage chamber. Specifically, as shown in Figures 27 and 28, when a second seal 6500 (for preventing the atomizing matrix from entering the base and leaking from the bottom of the base) is provided around the circumference of the atomizing core 5000 in the base 6300, the portion of the second seal 6500 opposite to the atomizing matrix inlet 5140 is provided with a groove 6510 to avoid the atomizing matrix inlet 5140.

[0137] It should be understood that other features of the atomizer 6000 are the same as those of the atomizer 3000 and will not be described in detail for the sake of brevity.
