[0002] This application claims priority and benefits of patent application No. 202420152445.0 filed with the State Intellectual Property Office of China on January 22, 2024, and the entire text of which is incorporated herein by reference. Technical Field

[0003] The present application relates to the technical field of aerosol generating devices, and in particular to a heating component and an aerosol generating device. Background Art

[0004] An aerosol-generating device can be used to heat an aerosol-forming substrate to form an aerosol through heating without combustion. In related art, an aerosol-generating device includes a heating pot, which contains the aerosol-forming substrate. After a period of use, the heating pot can contain residues that are difficult to clean, necessitating replacement. However, users may arbitrarily replace non-standard heating pots, resulting in uneven heating of the aerosol-forming substrate or other safety hazards. Summary of the Invention

[0005] The present application provides a heating component and an aerosol generating device.

[0006] The heating component of the embodiment of the present application includes a heating pot body and a first electrode. The heating pot body is formed with a accommodating cavity for accommodating an aerosol-forming substrate. The first electrode is fixed on the outer surface of the heating pot body and is used to form an electric arc outside the accommodating cavity.

[0007] The aerosol generating device of the embodiment of the present application fixes the first electrode on the outer surface of the heating pot body, and the first electrode and the heating pot body form an integral heating component. Therefore, after a period of use, the first electrode and the heating pot body can be taken out and replaced together, so that the aerosol generating device is not easily affected by the normal operation due to electrode loss, thereby improving the reliability and cleaning convenience of the aerosol generating device and the heating module. In addition, the restriction conditions for replacing the heating pot body are improved, avoiding the arbitrary replacement of non-standard heating pot bodies, and ensuring the puffing taste and safety of use. Furthermore, forming the electrode and the heating pot body into a whole is conducive to the efficient use of thermal efficiency and higher thermal efficiency. In addition, by measuring the change in the resistance value of the electrode formed on the heating pot body, the critical point for replacing the heating pot body can be determined and the replacement standard can be unified.

[0008] In some embodiments, the bottom of the heating pot is a flat bottom structure or a round bottom structure.

[0009] In this way, the bottom of the pot is a round bottom or a flat bottom structure, and the surface area of ​​the bottom of the pot is relatively larger, which increases the heat transfer area of ​​the electric arc to heat the heating pot body.

[0010] In some embodiments, the heating pot includes a main body and a flange formed on the top of the main body, and the main body is formed with a receiving cavity.

[0011] Thus, by forming a flange at the top, the heating pot body can be easily taken out and replaced.

[0012] In some embodiments, the outer surface of the heating pot body includes a pot bottom surface and an outer peripheral surface connected to the pot bottom surface, and the first electrode is at least partially disposed on the outer peripheral surface.

[0013] In this way, the first electrode can form a breakdown path on the outer peripheral surface of the heating pot body and the outer side of the pot bottom surface, thereby generating an arc for heating, with high space utilization, which is conducive to the miniaturization of the heating component.

[0014] In some embodiments, the first electrode includes a first conductive portion and a second conductive portion, the first conductive portion is closer to the bottom of the heating pot than the second conductive portion, the first conductive portion extends along the circumference of the heating pot, and along the circumference of the heating pot, the size of the second conductive portion is smaller than the size of the first conductive portion.

[0015] Thus, such a configuration can increase the thermal resistance of the first electrode, reduce heat transfer upward from the first conductive portion, and reduce the temperature rise of the first electrode.

[0016] In some embodiments, the first conductive portion surrounds the heating pot along the circumference of the heating pot to form a closed ring.

[0017] In this way, when a magnetic field is provided at the arc, the first conductive portion is in a closed ring shape, which is conducive to the magnetic field driving the arc to rotate, and the arc is continuous along the rotation trajectory of the circumference of the heating pot body.

[0018] In some embodiments, the first electrode also includes a third conductive portion, the second conductive portion connects the first conductive portion and the third conductive portion, the second conductive portion is closer to the bottom of the heating pot body relative to the third conductive portion, the third conductive portion extends along the circumference of the heating pot body, and a fracture is formed on the third conductive portion so that the third conductive portion includes at least two segments distributed at intervals along the circumference of the heating pot body.

[0019] In this way, the resistance value of the first electrode or the voltage across the first electrode can be detected by forming a fracture through the third conductive part, and then the ablation condition of the first electrode can be confirmed by detecting the resistance value or voltage parameters, so that the heating component can be replaced in time according to the ablation condition of the first electrode.

[0020] In some embodiments, the heating component includes a second electrode located outside the accommodating cavity, the second electrode is spaced apart from the first electrode, and an arc is formed between the first electrode and the second electrode when power is supplied to the first electrode and the second electrode.

[0021] In this way, the aerosol-forming substrate in the accommodating cavity is heated by forming an arc between the first electrode and the second electrode.

[0022] In some embodiments, the second electrode is fixed to the outer surface of the heating pot.

[0023] In this way, the arc formed between the first electrode and the second electrode is close to the outer surface of the heating pot body, which is beneficial to improving the heating efficiency.

[0024] In some embodiments, the second electrode is fixed at the center of the bottom of the heating pot.

[0025] In this way, the second electrode forms an arc between the center of the pot bottom and the first electrode on the outer peripheral surface, which is conducive to uniform arc heating.

[0026] In some embodiments, the heating pot body includes a side wall and a pot bottom connected to the side wall, and the first electrode and the second electrode are both at least partially disposed on the side wall.

[0027] In this way, by arranging the first electrode and the second electrode on the side wall, the insulation can be strengthened, and the discharge ends are arranged at intervals on both sides of the pot bottom, and the position where the arc is generated between the two discharge ends is relatively fixed.

[0028] In some embodiments, the shortest connection line between the first electrode and the second electrode passes through the bottom of the heating pot.

[0029] In this way, the shortest connection line between the first electrode and the second electrode passes through the bottom of the heating pot, so that the arc is generated at the bottom of the pot, reducing the probability of the arc breaking down along the circumference of the heating pot and improving the heating efficiency.

[0030] In some embodiments, the pot bottom is a circular pot bottom with a flat bottom structure, the first electrode and the second electrode are arranged opposite to each other along the radial direction of the pot bottom, and the shortest connecting line passes through the center of the pot bottom.

[0031] In this way, the shortest connection between the first electrode and the second electrode along the outer surface of the heating pot passes through the center of the pot bottom, ensuring that the arc is generated at the center of the pot bottom, which is beneficial to the uniformity of heating and the stability of the heating position.

[0032] In some embodiments, the heating pot body includes a side wall and a pot bottom connected to the side wall, and the thickness of the side wall ranges from 0.5 mm to 1.0 mm. In some embodiments, the minimum thickness of the pot bottom ranges from 0.3 mm to 0.8 mm.

[0033] In this way, by setting the thickness of the bottom and side walls of the heating pot body within a reasonable range, the heating efficiency and the heating rate can be improved.

[0034] The aerosol generating device according to the embodiment of the present application includes a housing and the heating component according to any one of the above embodiments, and the heating pot is at least partially accommodated in the housing.

[0035] In some embodiments, the aerosol generating device further comprises an insulating insulator, wherein the insulating insulator forms an insulating space, the bottom of the heating pot is accommodated in the insulating space, and the electric arc is formed in the insulating space.

[0036] In this way, by arranging an insulating insulator outside the arc, the aerosol generating device can be insulated and protected, and at the same time, the formation of an insulating space can reduce heat loss and improve heating efficiency and heating rate.

[0037] In some embodiments, the aerosol generating device comprises a conductive component, the conductive component abutting the first electrode, for supplying power to the first electrode.

[0038] In this way, the conductive component is in contact with the first electrode to facilitate the replacement operation of the first electrode and the heating pot body.

[0059] Referring to Figures 1 and 2, the present application provides a heating component 100 and an aerosol generating device 1000. In the present application, the aerosol generating device 1000 refers to a device that can generate aerosols using an aerosol-forming substrate 20. The aerosol-forming substrate 20 is a flower, stem, or leaf product of a plant that has been processed to generate an aerosol after heating. An aerosol is a colloid formed by solid or liquid particles distributed in a gaseous medium. The user can inhale the aerosol into the oral cavity, nasal cavity, or lungs through the mouth or nose. The aerosol inhaled into the user's respiratory system can be used for various purposes such as food, medicine, health care, and entertainment.

[0060] Please refer to Figures 2 to 4. The heating component 100 of the embodiment of the present application includes a heating pot body 10 and a first electrode 110. The heating pot body 10 is formed with a accommodating cavity 101 for accommodating the aerosol-forming matrix 20. The first electrode 110 is fixed to the outer surface 103 of the heating pot body 10. The first electrode 110 is used to form an electric arc outside the accommodating cavity 101.

[0061] The aerosol generating device 1000 of the present embodiment secures the first electrode 110 to the outer surface 103 of the heating pot 10. The first electrode 110 and the heating pot 10 form an integrated heating component 100. After a period of use, the first electrode 110 and the heating pot 10 can be removed and replaced together. This reduces the restrictions on replacing the heating pot 10, avoids the need to arbitrarily replace non-standard heating pots, and ensures a good puffing experience and safe use. Furthermore, by replacing the first electrode 110 and the heating pot 10 together, the aerosol generating device 1000 is less likely to be affected by electrode wear and tear, thereby improving its reliability and ease of cleaning. Furthermore, the integration of the first electrode 110 and the heating pot 10 facilitates efficient utilization of thermal efficiency. Furthermore, the critical point for replacing the heating pot 10 can be determined by measuring the change in resistance of the first electrode 110, thereby standardizing replacement standards.

[0062] Specifically, the aerosol-forming substrate 20 in the accommodating cavity 101 may be in a fully solid or semi-solid state. For example, the aerosol-forming substrate 20 may be a paste or gel. Highly humid pastes and gels may be applied to the inner wall of the pot bottom 11 or filled into the pot bottom 11. In another example, a fully solid aerosol-forming substrate 20 may be in the form of relatively finely divided blocks or sheets. The aerosol-forming substrate 20 as a whole may have a certain degree of fluidity. The aerosol-forming substrate 20 may be placed in the accommodating cavity 101 or deposited on the bottom of the heating pot body 10.

[0063] The heating pot 10 has an opening 102. One end of the opening 102 forms the top of the heating pot 10. The bottom 11 opposes the top and encloses the bottom of the heating pot 10. In this application, the direction from the opening 102 of the heating pot 10 toward the bottom 11 is defined as the top-to-bottom direction, and the direction from the center of the opening 102 toward the geometric center of the bottom 11 is defined as the axial direction of the heating pot 10, i.e., the vertical direction of the heating element 100. The lateral direction of the heating element 100 is perpendicular to the vertical direction. The cross-sectional shapes of the inner and outer contours of the heating pot 10 include, but are not limited to, circular, elliptical, regular quadrilateral, rectangular, polygonal, and other polygons with rounded corners or curved edges. For example, this application assumes that the cross-sectional shapes of the inner and outer contours of the heating pot 10 are circular, and the circumferential direction of the outer contour cross-section is defined as the circumferential direction of the heating pot 10. The heating pot 10 can be made of a heat-resistant material, such as quartz, ceramic, or heat-resistant glass.

[0064] The first electrode 110 is in the form of a film and adheres to the outer surface 103 of the heating pot 10. The first electrode 110 may be formed on the outer surface 103 of the heating pot 10 by screen printing. The first electrode 110 may be made of a material with good electrical conductivity and heat resistance, for example, one or more of copper and copper alloys, tungsten and tungsten alloys, graphite, and carbon fiber. An adhesive may also be used to strengthen the connection between the first electrode 110 and the heating pot 10.

[0065] There is at least one first electrode 110 formed on the surface of the heating pot 10. In some embodiments, there is one first electrode 110, which can be configured to discharge with another electrode disposed outside the heating component 100 to generate an arc.

[0066] In other embodiments, there are two first electrodes 110. The two first electrodes 110 can be respectively disposed at the center of the pot bottom 11 and between the pot bottom 11 and the opening 102. The two first electrodes 110 face each other along the extension direction of the outer surface 103, and can discharge and generate an arc at the position closest to the two first electrodes 110. In this embodiment, the two first electrodes 110 can both extend along the circumference of the heating pot body 10, surround the heating pot body 10, and face each other along the circumference of the heating pot body 10.

[0067] In other embodiments, there are multiple first electrodes 110 , and the multiple first electrodes 110 can be configured so that every two adjacent first electrodes 110 are connected to opposite voltage ends, thereby discharging on the outer surface 103 of the heating pot body 10 to generate multiple arcs.

[0068] When there are two or more first electrodes 110 , the first electrodes 110 may all conduct the same voltage, and discharge with an electrode conducting another voltage to generate an arc.

[0069] In some embodiments, the bottom 11 of the heating pot body 10 is a flat bottom structure or a round bottom structure.

[0070] In this way, the pot bottom 11 has a round bottom or a flat bottom structure, and the surface area of ​​the pot bottom 11 is relatively larger, thereby increasing the heat transfer area of ​​the electric arc to heat the heating pot body 10.

[0071] Specifically, the pot bottom 11 has a flat bottom structure, and the pot bottom 11 may be a flat surface as a whole, and the connection between the pot bottom 11 and the side wall 12 may have a certain rounded corner.

[0072] The pot bottom 11 can be a rounded structure protruding outward along the circumference of the pot body. The inner and outer contours of the center of the pot bottom 11 are both arc-shaped, and the connection between the pot bottom 11 and the side wall 12 is a circular arc. The pot bottom 11 can also be flat at the center and transition to the side wall 12 via a circular arc connection surface. In this embodiment, the radius of curvature of the pot bottom surface 1031 is not limited.

[0073] Compared with the sharp shape of the pot bottom 11 , the pot bottom 11 has a flat or round bottom structure, which has better uniformity in heat transfer and a relatively large contact area with the arc.

[0074] Referring to FIG. 4 , in some embodiments, the heating pot body 10 includes a main body 13 and a flange 14 formed on the top of the main body 13 , and the main body 13 is formed with a receiving cavity 101 .

[0075] Thus, by forming the flange 14 at the top, the heating pot body 10 is easy to take and replace. The sealing member 30 wraps the edge of the flange 14, has a heat insulation effect, is convenient for hand-held taking of the heating pot body 10, and can simplify the replacement operation of the heating component 100.

[0076] Specifically, the body 13 includes a bottom 11 and sidewalls 12, which define a receiving cavity 101. The sidewalls 12 may extend axially along the heating pot body 10, connecting the bottom 11 with an opening 102 at the top. The aerosol-forming substrate 20 may enter the receiving cavity 101 through the opening 102. The aerosol-forming substrate 20 may be applied to the bottom 11 and sidewalls 12, poured or injected into the receiving cavity 101, or placed directly on the bottom 11 using a handheld or transfer tool.

[0077] The opening 102 can be defined by the inner circular surface of the top of the body 13. The sidewall 12 extends radially outward from the opening 102 along the body 13 to form a flange 14. The distance that the flange 14 extends radially in the heating pot body 10 is the length of the flange 14. The length of the flange 14 can be greater than the thickness of the sidewall 12, and is typically set to be significantly less than the diameter of the body 13. The thickness of the flange 14 can be the same as the thickness of the sidewall 12, or slightly greater or less than the thickness of the sidewall 12. In some embodiments, the direction in which the flange 14 extends outward can be radially in the body 13.

[0078] Referring to FIG. 2 and FIG. 3 , in some embodiments, the outer surface 103 of the heating pot body 10 includes a pot bottom surface 1031 and an outer peripheral surface 1032 connected to the pot bottom surface 1031 , and the first electrode 110 is disposed on the outer peripheral surface 1032 .

[0079] In this way, the first electrode 110 can form a breakdown path outside the outer peripheral surface 1032 and the bottom surface 1031 of the heating pot body 10, thereby generating an arc for heating, which has high space utilization and is conducive to the miniaturization of the heating component 100.

[0080] Specifically, the pot bottom surface 1031 can be a flat surface, or can include a flat surface and a circular transition surface. The flat pot bottom surface 1031 can extend radially along the heating pot body 10. The pot bottom surface 1031 can also be a circular surface, and the normal of the curved pot bottom surface 1031 can be aligned with the axial direction of the heating pot body 10. The outer peripheral surface 1032 connects to the edge of the pot bottom surface 1031 and extends upward from the pot bottom 11 along the axial direction of the heating pot body 10. The first electrode 110 can be disposed on the outer peripheral surface 1032 and close to the pot bottom surface 1031.

[0081] Continuing with Figures 2 and 3 , in some embodiments, the first electrode 110 includes a first conductive portion 111 and a second conductive portion 112. The first conductive portion 111 is closer to the bottom 11 of the heating pot 10 than the second conductive portion 112. The first conductive portion 111 extends along the circumference of the heating pot 10. Along the circumference of the heating pot 10, the second conductive portion 112 is smaller than the first conductive portion 111.

[0082] In some embodiments, the first electrode 110 further includes a third conductive portion 113 , the second conductive portion 112 connects the first conductive portion 111 and the third conductive portion 113 , the second conductive portion 112 is closer to the bottom 11 of the heating pot body 10 relative to the third conductive portion 113 , and the third conductive portion 113 extends along the circumference of the heating pot body 10 .

[0083] Thus, the second conductive portion 112 is narrower than the first conductive portion 111 and the third conductive portion 113 in the circumferential direction of the heating pot body 10 , thereby increasing the thermal resistance of the first electrode 110 , reducing the upward heat transfer of the first conductive portion 111 , and reducing the temperature rise at the upper end of the heating component 100 .

[0084] Specifically, the first electrode 110 can have various shapes and be combined in various forms, forming a variety of patterns on the outer peripheral surface 1032. This can control the direction of the current and the location of the discharge end, thereby affecting the heat dissipation path. The first conductive portion 111 and the third conductive portion 113 can both be annular, surrounding the heating pot 10 along the circumference and spaced a predetermined distance apart along the axial direction of the heating pot 10. The first conductive portion 111 is closer to the pot bottom 11 than the third conductive portion 113, and the discharge end of the first electrode 110, where the arc is formed, is located on the first conductive portion 111.

[0085] The second conductive portion 112 is located on the outer circumferential surface 1032 between the first conductive portion 111 and the third conductive portion 113, with one end connected to the first conductive portion 111 and the other end connected to the third conductive portion 113. Each first conductive portion 111 and third conductive portion 113 are connected by at least one second conductive portion 112. Along the circumference of the heating pot 10, the size of the second conductive portion 112 is smaller than the size of the first conductive portion 111, and can also be smaller than the size of the third conductive portion 113. The second conductive portion 112 can be strip-shaped and can extend between the first conductive portion 111 and the third conductive portion 113 along a straight path or a curved path. The extension direction of the second conductive portion 112 can form a certain angle with the circumference of the heating pot 10 on the outer circumferential surface 1032. When an arc is formed on the first conductive part 111 and high temperature is generated, the thin strip-shaped second conductive part 112 increases the thermal resistance of heat transfer from the first conductive part 111 to the third conductive part 113, thereby reducing the temperature rise of the structure above the first electrode 110, reducing heat loss and lowering the heat resistance threshold of other structural parts on the upper end of the heating component 100.

[0086] Exemplarily, as shown in Figure 3, the direction in which the second conductive portion 112 extends on the outer peripheral surface 1032 is perpendicular to the circumference of the heating pot body 10 and extends in a straight path. The first conductive portion 111, the third conductive portion 113 and the second conductive portion 112 form a pattern that is approximately in the shape of an "I" on the outer peripheral surface 1032.

[0087] In some embodiments, the first conductive portion 111 surrounds the heating pot body 10 along the circumference of the heating pot body 10 to form a closed ring.

[0088] In this way, when a magnetic field is provided at the arc, the first conductive portion 111 is in a closed ring shape, which is conducive to the magnetic field driving the arc to rotate, and the arc is continuous along the circumferential rotation trajectory of the heating pot body 10.

[0089] Specifically, the aerosol generating device 1000 may be provided with a magnetic member (not shown). The magnetic flux component of the magnetic field generated by the magnetic member (not shown) perpendicular to the arc can drive the arc to rotate around the heating pot body 10. The first conductive portion 111 is in the form of a closed ring, which can be a circular ring, an elliptical ring, or a ring with multiple segments of varying curvature. The first conductive portion 111 surrounds the outer surface 103 along the circumference of the heating pot body 10 for at least one revolution. The first conductive portion 111 extends continuously along the circumference of the heating pot body 10. The formed arc can rotate continuously as it rotates around the heating pot body 10, making it less likely to break, and improving heating efficiency.

[0090] In other embodiments, a certain notch may appear on the first conductive portion 111, and the notch forms a gap much smaller than the outer diameter of the heating pot 10 along the circumference of the heating pot 10. Accordingly, the arc will be extinguished in a very short time, and the extinguished arc is not visible to the naked eye.

[0091] Referring to FIG. 2 , in some embodiments, the third conductive portion 113 is formed with a fracture 1130 so that the third conductive portion 113 includes at least two segments spaced apart along the circumference of the heating pot 10 .

[0092] In this way, the resistance value of the first electrode 110 or the voltage across the first electrode 110 can be detected through the fracture 1130, and then the ablation condition of the first electrode 110 can be confirmed by detecting the resistance value or voltage parameters, so that the heating component 100 can be replaced in time according to the ablation condition of the first electrode 110.

[0093] Specifically, the third conductive portion 113 forms a fracture 1130, and the fracture 1130 can be a sub-conductive portion 1131 that separates the third conductive portion 113 into two semicircular rings. The sub-conductive portions 1131 extend along the circumference of the heating pot body 10 and are spaced apart from each other. A breakdown voltage is applied to the first electrode 110, which can be connected to an external power supply through the third conductive portion 113. The two sub-conductive portions 1131 can be connected to the voltage of the same pole, or can be connected to opposite poles. The first electrode 110 will be ablated during the discharge process. When the first electrode 110 is ablated to the point where the voltage or resistance value changes to a certain threshold, the heating component 100 can be replaced in time to maintain the purity of the aerosol-forming matrix 20. By detecting the change in resistance value or breakdown voltage after the ablation of the first electrode 110, the life of the pot body can be detected.

[0094] In some embodiments, the first electrode 110 discharges in the first conductive portion 111. The thickness and width of the first conductive portion 111 decrease after ablation, the overall resistance of the first electrode 110 increases, and the breakdown voltage increases. A low-voltage detection circuit can be connected on both sides of the fracture 1130 to detect the change in resistance of the first electrode 110 after ablation. The third conductive portion 113 surrounds the circumference of the heating pot body 10. The length of the third conductive portion 113 is relatively long, which can increase the basic resistance value or voltage of the detection circuit. This design also raises the product threshold and has a certain anti-wildcarding effect.

[0095] Referring to Figures 3 to 5, in some embodiments, the heating component 100 includes a second electrode 120 located outside the accommodating cavity 101. The second electrode 120 is spaced apart from the first electrode 110. When the first electrode 110 and the second electrode 120 are energized, an arc is formed between the first electrode 110 and the second electrode 120.

[0096] In this way, the aerosol-forming substrate 20 in the accommodating cavity 101 is heated by forming an arc between the first electrode 110 and the second electrode 120 .

[0097] Specifically, the first electrode 110 and the second electrode 120 are configured to apply a breakdown voltage when energized. The first electrode 110 and the second electrode 120 are connected to either the cathode or the anode, respectively. The first electrode 110 and the second electrode 120 are spaced apart, forming a gap between the first electrode 110 and the second electrode 120. A gas, such as air, exists in the gap. Arc discharge is a gas discharge phenomenon in which, under the action of a strong electric field, the gas in the gap between the first electrode 110 and the second electrode 120 is ionized to form a plasma, a process known as arcing. The generation of an arc is accompanied by a dazzling glow and a large amount of heat. When the first electrode 110 and the second electrode 120 are energized, an arc is formed outside the accommodating cavity 101, rapidly heating the aerosol-forming substrate 20 in the accommodating cavity 101, causing it to atomize and form an aerosol. The heating pot 10 and the first electrode 110 rapidly heat up during the arcing process, and heat can be transferred to the aerosol-forming substrate 20 through heat transfer and thermal radiation.

[0098] In some embodiments, there is one first electrode 110. The first electrode 110 can be arranged to extend along the circumference of the heating pot 10 from the outer peripheral surface 1032 of the heating pot 10, forming a ring-shaped first electrode 110. The second electrode 120 can be positioned directly opposite the center of the pot bottom surface 1031, with the first electrode 110 positioned above the second electrode 120. An arc is generated by discharge between the second electrode 120 and the nearest end of the first electrode 110.

[0099] Referring to FIG. 3 , in some embodiments, the second electrode 120 is fixed to the outer surface 103 of the heating pot 10 .

[0100] In this way, the arc formed between the first electrode 110 and the second electrode 120 is close to the outer surface 103 of the heating pot body 10, which is beneficial to improving the heating efficiency.

[0101] Specifically, the second electrode 120 can be formed on the outer surface 103 of the heating pot body 10 by printing, plating, or coating, or can be fixed to the outer surface 103 via a structural member. The second electrode 120 can be fixed to the pot bottom surface 1031 or the outer peripheral surface 1032, and separated from the first electrode 110 by a certain distance along the extension direction of the outer surface 103. The material selected for the second electrode 120 can be one or more of copper or copper alloy, tungsten or tungsten alloy, graphite, carbon fiber, etc., and the material of the second electrode 120 can be the same as or different from that of the first electrode 110. The first electrode 110 and the second electrode 120 are both fixed to the outer surface 103 of the heating pot body 10. When power is applied, a strong electric field is formed on the outer surface 103 between the first electrode 110 and the second electrode 120, causing an electric arc to form on the outer surface 103 of the heating pot body 10.

[0102] Please refer to FIG. 3 to FIG. 5 . In some embodiments, the second electrode 120 is fixed at the center of the bottom 11 of the heating pot 10 .

[0103] In this way, the second electrode 120 forms an arc between the center of the pot bottom 11 and the first electrode 110 on the outer peripheral surface 1032, which is conducive to uniform arc heating.

[0104] As shown in FIG3 , in some embodiments, the second electrode 120 is in the form of a film and is formed in the center of the pot bottom surface 1031 through a printing process. As shown in FIG5 , in other embodiments, the second electrode 120 can be in the form of a disk and can be fixed to the center of the pot bottom 11 by other structural members (not shown). The first electrode 110 surrounds the heating pot body 10 on the outer peripheral surface 1032 and can partially extend to the arc surface of the pot bottom 11. When the first electrode 110 and the second electrode 120 are energized, an arc can be generated along the path shown by the BB line in FIG4 or the CC line in FIG5 . The arc can cover the entire pot bottom surface 1031, which helps to improve the heat transfer efficiency from the arc to the heating pot body 10.

[0105] Referring to FIG. 11 , in some embodiments, the heating pot body 10 includes a side wall 12 and a pot bottom 11 connected to the side wall 12 , and the first electrode 110 and the second electrode 120 are at least partially disposed on the side wall 12 .

[0106] Thus, by arranging the first electrode 110 and the second electrode 120 on the side wall 12 , insulation can be enhanced, and the discharge ends 140 are spaced apart on both sides of the pot bottom 11 , so that the formed arc can easily cover the pot bottom surface 1031 .

[0107] Specifically, the pot bottom 11 and the sidewall 12 define a receiving cavity 101. The sidewall 12 may surround the central axis of the heating pot body 10 and extend axially along the heating pot body 10, connecting the pot bottom 11 and the opening 102. The pot bottom 11 and the sidewall 12 may have equal thickness or the same thickness range. The thickness of the pot bottom 11 and the sidewall 12 may also be different.

[0108] In this embodiment, the pot bottom 11 can be a round or flat bottom structure. The outer contour of the heating pot body 10 can be circular, oval, square, olive, racetrack, or other polygonal shapes with curved edges. For example, the cross-sectional shape of the outer contour of the heating pot body 10 can be circular or nearly circular. The outer diameter of the heating pot body 10 ranges from 5 mm to 20 mm (inclusive). The diameter of the outer circumferential surface 1032 of the side wall 12 can be considered the outer diameter of the heating pot body 10. The opening 102 can be defined by the inner circumference of the side wall 12 at the top.

[0109] The discharge end 140 and the conductive portion 130 of the first electrode 110 and the second electrode 120 can be disposed on the side wall 12, and the portion of the conductive portion 130 connected to the discharge end 140 can be attached to or in contact with the outer peripheral surface 1032 of the side wall 12. The discharge end 140 of the first electrode 110 and the second electrode 120 can be placed against the side wall 12 near the pot bottom 11.

[0110] The first electrodes 110 and the second electrodes 120 are arranged in pairs. The number of first electrodes 110 and second electrodes 120 can be one, two, three, or more. Multiple pairs of first electrodes 110 and second electrodes 120 can be spaced apart along the circumference of the heating pot 10. Furthermore, multiple pairs of first electrodes 110 and second electrodes 120 can be evenly distributed along the circumference of the heating pot 10 on the sidewall 12. The shortest connecting line between each pair of first electrodes 110 and second electrodes 120 passes through the center of the bottom 11 of the heating pot 10.

[0111] Please refer to the figure, in some embodiments, the shortest connection line between the first electrode 110 and the second electrode 120 passes through the bottom 11 of the heating pot 10 .

[0112] In this way, the shortest connection line between the first electrode 110 and the second electrode 120 passes through the bottom 11 of the heating pot 10, so that the arc is generated at the bottom 11, reducing the probability of the arc breaking down along the circumference of the heating pot 10 and improving the heating efficiency.

[0113] It should be noted that when power is applied to the first and second electrodes 110, 120, discharge occurs between the two ends with the shortest distance. To ensure that the arc is generated between the discharge ends 140 of the first and second electrodes 110, 120, the line connecting the discharge ends 140 of the first and second electrodes 110, 120 needs to be the shortest line. It should also be noted that the shortest line refers to the shortest line between the discharge ends 140 in the air medium, and the shortest line does not pass through the wall of the heating pot 10. Alternatively, the shortest line is the shortest line segment between the first and second electrodes 110, 120 at the outer surface 103 of the heating pot 10. For example, in the embodiment shown in FIG11, line MM is the shortest line between the first and second electrodes 110, 120, and the arc is generated on line MM. For another example, in the embodiment shown in FIG12, line NN is the shortest line between the first and second electrodes 110, 120, and the arc is generated on line NN. The MM line and the NN line are both line segments on the pot bottom surface 1031 .

[0114] In some embodiments, the pot bottom 11 has a round bottom structure, and the shortest connecting line between the first electrode 110 and the second electrode 120 passes through the pot bottom 11 of the heating pot body 10, such as the MM connecting line in Figure 11. The minimum distance between the first electrode 110 and the second electrode 120 in the circumferential direction of the heating pot body 10 is greater than the distance of the connecting line of the discharge end 140 passing through the pot bottom 11. For example, the LL connecting line shown in Figure 10 is a connecting line between the discharge end 140 of the first electrode 110 and the second electrode 120 along the circumference of the heating pot body 10, and the length of the MM connecting line is shorter than the length of the LL connecting line. The discharge end 140 of the first electrode 110 and the second electrode 120 is closer to the central axis of the heating pot body 10 or the center of the pot bottom 11 relative to the conductive portion 130.

[0115] Please refer to Figure 12. In some embodiments, the pot bottom 11 is a circular pot bottom 11 with a flat bottom structure. The first electrode 110 and the second electrode 120 are arranged opposite to each other along the radial direction of the heating pot body 10, and the shortest connecting line passes through the center of the pot bottom 11.

[0116] In this way, the shortest connection between the first electrode 110 and the second electrode 120 along the outer surface 103 of the heating pot body 10 passes through the center of the pot bottom 11, ensuring that the arc is generated at the center of the pot bottom 11, which is beneficial to the uniformity of heating and the stability of the heating position.

[0117] Specifically, when energized, the first electrode 110, whose discharge end 140 discharges to form an arc, and the second electrode 120 form an electrode pair. The electrode pair is arranged radially along the heating pot body 10, with the first electrode 110 and the second electrode 120 located at opposite ends of the same radial direction of the heating pot body 10. As previously described, the shortest line connecting the first electrode 110 and the second electrode 120 is the shortest line segment along the outer surface 103 of the heating pot body 10 between the discharge end 140 of the first electrode 110 and the second electrode 120. When energized, the first electrode 110 and the second electrode 120 discharge along the shortest line NN to generate an arc. The shortest line NN passes through the center of the pot bottom 11, allowing the arc to be generated at or near the center of the pot bottom 11, or to pass through the center of the pot bottom surface 1031.

[0118] Referring to FIG. 4 , in some embodiments, the heating pot body 10 includes a side wall 12 and a pot bottom 11 connected to the side wall 12. The side wall 12 has a thickness D ranging from 0.5 mm to 1.0 mm (inclusive). In some embodiments, the pot bottom 11 has a minimum thickness d ranging from 0.3 mm to 0.8 mm (inclusive).

[0119] In this way, by setting the thickness of the bottom and side wall 12 of the heating pot body 10 within a reasonable range, and further setting the thickness of the pot bottom 11 to be smaller than the thickness D of the side wall 12, the heating efficiency and the heating rate can be improved.

[0120] Specifically, the sidewall 12 can be formed around the central axis of the heating pot body 10. The sidewall 12 can have a uniform thickness. The thickness D of the sidewall 12 can also vary in a gradient or slope. The sidewall 12 can also have a uniform thickness over a large area, with the thickness decreasing or increasing in some areas. For example, the thickness D of the sidewall 12 can be 0.5 mm to 1.0 mm, 0.6 mm to 0.9 mm, 0.63 mm to 0.88 mm, 0.7 mm to 0.9 mm, 0.75 mm to 0.8 mm, etc. For another example, the thickness D of the sidewall 12 can be 0.5 mm, 0.54 mm, 0.65 mm, 0.72 mm, 0.81 mm, 0.97 mm, or 1.0 mm.

[0121] In some embodiments, the sidewalls 12 and the pot bottom 11 may be of equal thickness. In other embodiments, the thickness H of the pot bottom 11 may be less than the thickness D of the sidewalls 12, with the thickness gradually tapering at the junction of the pot bottom 11 and the sidewalls 12. The overall thickness H of the pot bottom 11 may be uniform. The pot bottom 11 may be locally thinned to reduce thermal resistance between the arc and the aerosol-forming substrate 20. Where the thickness of the pot bottom 11 varies, the thickness may vary gradually to avoid discontinuities between the inner and outer surfaces 103 of the heated pot body 10. For example, the thickness d at the thinnest point of the pot bottom 11 may range from 0.3 mm to 0.8 mm, 0.4 mm to 0.7 mm, 0.45 mm to 0.6 mm, 0.5 mm to 0.58 mm, and so on. For another example, the minimum wall thickness d of the pot bottom 11 may range from 0.3 mm to 0.37 mm, 0.46 mm, 0.57 mm, 0.68 mm, 0.75 mm, or 0.8 mm.

[0122] Please refer to Figures 2 to 4 again. The heating component 100 of the embodiment of the present application further includes a sealing member 30. The sealing member 30 is fixed on the heating pot body 10 and extends along the circumference of the heating pot body 10.

[0123] In this way, the sealing member 30 and the first electrode 110 can be replaced together with the heating pot body 10 , thereby reducing aging and wear of the sealing member 30 and ensuring that the sealing performance of the heating component 100 is effective for a long time.

[0124] Specifically, the seal 30 can be made of an insulating material with a certain degree of elasticity, such as rubber, silicone, or resin. In some embodiments, the seal 30 can be made into a rubber ring or a rubber strip and sleeved on the heating pot body 10. The seal 30 and the heating pot body 10 can be interference fit so that the seal 30 and the heating pot body 10 remain as a whole during replacement and use. In other embodiments, the seal 30 can also be formed by applying a sealing glue to the heating pot body 10 and curing it. The seal 30 can be fixed to the heating pot body 10 in an annular shape, extending along the axial direction of the heating pot body 10 to increase the contact area.

[0125] Referring to FIG. 4 , in some embodiments, the heating pot body 10 has an opening 102 opposite to the pot bottom 11 of the heating pot body 10 , and the sealing member 30 is disposed at the opening 102 .

[0126] In this way, the opening 102 of the heating pot body 10 is sealed by the sealing member 30 , so that the accommodating cavity 101 can be sealed and isolated.

[0127] Specifically, the aerosol-forming substrate 20 is atomized in the accommodating chamber 101 to form an aerosol, which can overflow from the opening 102 for inhalation. The seal 30 can be the edge of the heating pot 10 positioned over the opening 102. When the heating pot 10 is installed in the heating module or the aerosol generating device 1000, the seal 30 can seal the accommodating chamber 101 at the opening 102, thereby reducing the diffusion of the aerosol within the aerosol generating device 1000. When the first electrode 110 (and the second electrode 120) are energized, an arc is generated outside the accommodating chamber 101 to heat the atomized aerosol-forming substrate 20. The heat generated by the arc can be transferred into the accommodating chamber 101 through the first electrode 110, the second electrode 120, and the heating pot 10 via heat transfer and heat radiation. The interior and exterior of the accommodating chamber 101 can be sealed and isolated by a seal 30 at the opening 102. This prevents odors from entering the accommodating chamber 101 during the discharge process and prevents the arc from directly contacting the aerosol and / or the aerosol-forming substrate 20, thereby ensuring the purity of the aerosol-forming substrate 20 and the quality of the aerosol. Furthermore, the provision of the seal 30 at the opening 102 also facilitates thermal insulation of the top of the heating pot 10.

[0128] Continuing to refer to FIG. 4 , in some embodiments, the flange 14 is formed with an opening 102 , and the sealing member 30 wraps around the edge of the flange 14 .

[0129] In this way, the sealing effect can be enhanced by wrapping the edge of the flange 14 with sealant.

[0130] Specifically, the flange 14 may extend along the circumference of the heating pot body 10 from the top of the side wall 12 in a direction away from the accommodating cavity 101. As previously described, the inner circle of the top of the side wall 12, i.e., the inner circle of the flange 14, defines the opening 102. The edge of the flange 14 is away from the accommodating cavity 101 relative to the side wall 12. The seal 30 wraps around the edge of the flange 14 from the outer periphery of the opening 102, and the seal 30 and the flange 14 are tightly fitted. The heating pot body 10 can be assembled by the angle formed by the flange 14 and the side wall 12. The seal 30 wraps around the edge of the flange 14, providing a certain cushioning and bonding effect during assembly.

[0131] In other embodiments, the seal 30 is fixed to the outer circumferential surface 1032 of the body 13. In the axial direction of the heating pot 10, the seal 30 is located between the opening 102 and the pot bottom 11. In this embodiment, the assembly surface between the heating pot 10 and other structural components is located between the opening 102 and the pot bottom 11, and the seal 30 can cover a portion of the outer circumferential surface 1032 at the assembly location.

[0132] 3 and 8 , in some embodiments, the seal 30 includes a first sealing portion 31 and a second sealing portion 32 connected to the first sealing portion 31 . The first sealing portion 31 wraps around the flange 14 , and the second sealing portion 32 surrounds the outer circumferential surface 1032 of the body 13 .

[0133] In this way, by wrapping the flange 14 with the first sealing portion 31 and surrounding the outer peripheral surface 1032 with the second sealing portion 32, the shape of the sealing member 30 and the sealed portion of the heating pot body 10 can be more closely matched, the contact area can be increased, and a better sealing effect can be achieved.

[0134] Specifically, the first sealing portion 31 can extend outward from the inner circumference of the opening 102 and cling to the top, side and bottom of the flange 14, forming an enclosure for the flange 14. The first sealing portion 31 is annular as a whole with a hollow space, and the flange 14 extends into the hollow space of the first sealing portion 31. The second sealing portion 32 is annular as a whole, extending downward from the bottom of the flange 14 along the axial direction of the heating pot body 10, and clinging to the outer peripheral surface 1032 of the side wall 12. The connection between the first sealing portion 31 and the second sealing portion 32 can be an outer wall surface that fits tightly against the connection between the side wall 12 and the flange 14. The first sealing portion 31 and the second sealing portion 32 are parts of the sealing member 30 that have different positions and shapes. The first sealing portion 31 and the second sealing portion 32 can be integrally formed as one component.

[0135] Please continue to refer to Figures 4 and 8. In some embodiments, the first sealing portion 31 includes a first sealing surface 311, and the second sealing portion 32 includes a second sealing surface 321. The second sealing surface 321 is connected to the first sealing surface 311 and faces away from the outer peripheral surface 1032 of the main body 13. The first sealing surface 311 faces the bottom of the heating pot body 10, and the second sealing surface 321 extends along the circumference of the heating pot body 10.

[0136] In this way, the heating pot body 10 can be sealed in both the axial and circumferential directions by using the same seal 30, which reduces the number of seals 30, simplifies assembly, and helps to improve space utilization.

[0137] Specifically, the portion of the first sealing portion 31 wrapped below the flange 14, facing away from the flange 14, is a first sealing surface 311. The first sealing surface 311 may extend in the same direction as the flange 14. For example, if the flange 14 extends outward along the circumference of the heating pot 10, the first sealing surface 311 may extend along the circumference of the heating pot 10 on the side of the flange 14 facing the bottom of the heating pot 10. The first sealing surface 311 may form a certain angle with the axial direction of the heating pot 10. The second sealing surface 321 is the surface of the second sealing portion 32 facing away from the sidewall 12.

[0138] In some embodiments, the heating pot 10 is assembled into the housing 200 from top to bottom, with the seal 30 wrapping around the flange 14 and resting against the housing 200. The first sealing surface 311 is attached to the top of the housing 200, and the second sealing surface 321 is in close contact with the side of the housing 200, sealing the assembly gap between the housing 200 and the flange 14.

[0139] In some embodiments, the second sealing surface 321 is formed with a sealing protrusion 322 , and the sealing protrusion 322 extends along the circumference of the heating pot body 10 .

[0140] In this way, by extending the second sealing surface 321 along the circumferential direction of the heating pot body 10 to form the sealing protrusion 322, the contact surface between the sealing member 30 and the heating pot body 10 and other sealed components can be increased, thereby improving the sealing effect.

[0141] Specifically, the second sealing surface 321 is pressed against the housing 200, and the sealing protrusion 322 abuts against the housing 200. The height of the sealing protrusion 322 along the circumference of the heating pot 10 can be significantly less than the width of the second sealing surface 321. When the housing 200 and the sealing member 30 are pressed together, the sealing protrusion 322 can deform in the direction of the protrusion to increase the contact area between the second sealing surface 321 and the housing 200.

[0142] 6 and 7 , the aerosol generating device 1000 according to the embodiment of the present application includes a housing 200 and the heating component 100 according to any of the above embodiments, and the heating pot 10 is at least partially accommodated in the housing 200 .

[0143] In this way, the heating pot body 10 is accommodated in the shell body 200, and the shell body 200 can provide support and protection for the heating pot body 10 and facilitate assembly.

[0144] Specifically, the main body 13 of the heating pot 10 is accommodated in the housing 200, and the flange 14 can at least partially extend outside the housing 200. The heating pot 10 and the housing 200 are detachably connected. When the heating pot 10 is replaced, the seal 30 and the first electrode 110 can be removed from the housing 200 along with the heating pot 10.

[0145] Referring to FIG. 7 , in some embodiments, the sealing member 30 seals the gap formed between the housing 200 and the heating pot 10 .

[0146] In this way, the heating pot body 10 is installed in the shell 200, and the gap formed between the shell 200 and the heating pot body 10 is sealed by the sealing member 30 to prevent discharge or heat-generated odor from mixing into the aerosol.

[0147] Specifically, the heating pot body 10 is housed in the shell 200, with the side walls 12 and the pot bottom 11 spaced a certain distance from the wall of the shell 200, forming a gap. The shell 200 may surround the heating pot body 10 and be connected to the heating pot body 10 at the flange 14. The heating pot body 10 can be extruded and assembled with the shell 200 through a seal 30, and the first sealing surface 311 and the second sealing surface 321 are extruded assembly surfaces. The seal 30 is wrapped around the flange 14, and the first sealing surface 311 and the second sealing surface 321 are in close contact with the shell 200, sealing the gap between the shell 200 and the heating pot body 10. An electric arc is generated between the heating pot body 10 and the shell 200, and an aerosol is generated in the accommodating chamber 101. The accommodating chamber 101 and the shell 200 are sealed and isolated by the seal 30 to maintain the purity of the aerosol.

[0148] In other embodiments, the position where the heating pot body 10 and the shell 200 abut each other may be on the outer peripheral surface 1032. In this embodiment, the seal 30 is arranged at the position where the heating pot body 10 and the shell 200 abut each other to seal the gap between the shell 200 and the heating pot body 10.

[0149] 6 and 7 , in some embodiments, the aerosol generating device 1000 includes a nozzle assembly 300 , which covers the accommodating cavity 101 and compresses the sealing member 30 .

[0150] In this way, gas can be blown into the accommodating chamber 101 through the nozzle assembly 300 , and aerosol generated in the accommodating chamber 101 can be sucked away by suction.

[0151] Specifically, the nozzle assembly 300 can be disposed at one end of the housing 200. The nozzle assembly 300 can be disposed on top of the heating element 100 and can be extruded and assembled with the heating pot 10 at the flange 14. The seal 30 can seal the assembly gap between the nozzle assembly 300 and the flange 14. The nozzle assembly 300 can cover the opening 102, allowing aerosol generated in the accommodating chamber 101 to overflow from the opening 102 and be inhaled through the nozzle assembly 300.

[0152] Referring to Figures 7 and 8 , in some embodiments, the seal 30 wraps around the flange 14 , forming an integral unit with the heating pot 10 . The heating pot 10 rests against the housing 200 via the flange 14 , with the first sealing surface 311 resting against the top of the housing. The side of the first sealing portion 31 facing away from the first sealing surface 311 is pressed against the nozzle assembly 300 . The nozzle assembly 300 is extruded and assembled with the heating pot 10 and the housing 2000 via the seal 30 , providing stable support, high reliability, and excellent thermal insulation. Both the nozzle assembly 300 and the heating pot 10 , and the heating pot 10 and the housing 200 , are detachably connected, making replacement of the heating pot 10 easy.

[0153] Please refer to Figure 7. In some embodiments, the aerosol generating device 1000 further includes an insulating insulator 400. The insulating insulator 400 forms an insulating space 401. The bottom 11 of the heating pot 10 is accommodated in the insulating space 401, and the electric arc is formed in the insulating space 401.

[0154] In this way, by providing an insulating insulator 400 outside the arc, the aerosol generating device 1000 can be insulated and protected, while reducing heat loss in the insulating space 401 and improving heating efficiency and heating rate.

[0155] Specifically, the insulating body 400 can be disposed below the heating pot body 10. The insulating body 400 can partially cover the side wall 12 and enclose the pot bottom 11. An insulating space 401 is defined between the inner wall surface of the insulating body 400 and the pot bottom surface 1031. The insulating space 401 can be separated from the accommodating cavity 101 by the pot bottom 11. The first electrode 110 can partially extend into the insulating space 401, and the second electrode 120 can be disposed on the pot bottom 11 or the insulating body 400. When the first and second electrodes 110 and 120 are energized, discharge occurs in the insulating space 401 below the pot bottom 11, generating an arc. The insulating body 400 can isolate odors and sparks during discharge.

[0156] The insulating body 400 can be made of a heat-resistant insulating material, such as quartz or heat-resistant glass. The heating pot 10 transfers arc heat to the aerosol-forming matrix 20 in the accommodating cavity 101. The insulating body 400 isolates the arc, preventing damage to other components from the high-voltage discharge and reducing the transfer of arc heat to other components.

[0157] 7 and 9 , in some embodiments, the aerosol generating device 1000 includes a conductive component 500 , which abuts against the first electrode 110 to supply power to the first electrode 110 .

[0158] In this way, the conductive component 500 is in contact with the first electrode 110 and is electrically connected to the first electrode 110 , which facilitates the replacement operation of the first electrode 110 and the heating pot body 10 .

[0159] Specifically, the conductive component 500 can be in contact with the first electrode 110 through an elastic conductive member (not shown). When the heating component 100 is installed in the housing 200, the elastic conductive member (not shown) presses the first electrode 110. When the heating component 100 is removed from the housing 200, the elastic conductive member (not shown) relaxes and detaches from the first electrode 110. The conductive component 500 can be connected to one of the output terminals of a transformer (not shown), and the other output terminal of the transformer (not shown) is connected to the second electrode 120. When the conductive component 500 contacts the first electrode 110, a high-voltage electric field is applied between the first electrode 110 and the second electrode 120. In other embodiments, the conductive component 500 can be connected to both output terminals of the transformer (not shown) at the same time, and the first electrode 110 can be connected to the two poles of the high-voltage electric field respectively through the sub-conductive portion 1131.

[0160] The first electrode 110 is in contact with the conductive component 500 and is electrically connected at the upper end of the first electrode 110 along the axial direction of the heating pot 10 , so as to prevent the arc from striking the conductive component 500 .

[0161] In the aerosol generating device 1000 of the embodiment of the present application, the first electrode 110 is disposed on the outer surface 103 of the heating pot 10, the seal 30 is integrally formed with the heating pot 10, and the heating component 100 is detachably connected to the housing 200. The first electrode 110, the seal 30, and the heating pot 10 can be removed from the aerosol generating device 1000 and replaced after a period of use, facilitating cleaning and maintenance of the aerosol generating device 1000. This increases the frequency of replacement of the first electrode 110 and the seal 30, reduces failures caused by ablation of the first electrode 110 or aging of the seal 30, and improves the reliability and service life of the aerosol generating device 1000.
