[0004] 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 receiving cavity for receiving an aerosol-forming substrate. The first electrode is fixed to the outer surface of the heating pot body. The first electrode is used to form an electric arc outside the receiving cavity.

[0005] 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, so that 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 electrode loss and the normal operation is affected, and the reliability and cleaning convenience of the aerosol generating device and the heating module are improved. In addition, the restriction conditions for replacing the heating pot body are improved, and the arbitrary replacement of non-standard heating pot bodies is avoided, which ensures the suction taste and safety of use. Furthermore, the electrode and the heating pot body are formed into a whole, which 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 of replacement of the heating pot body can be determined, and the replacement standard can be unified.

[0006] In some embodiments, the bottom of the heating pot is a flat bottom structure or a round bottom structure.

[0007] 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.

[0008] In some embodiments, the heating pot body 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.

[0009] In this way, by forming a flange at the top, the heating pot body can be easily taken out and replaced.

[0010] 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.

[0011] 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.

[0012] In some embodiments, the first electrode includes a first conductive part and a second conductive part, the first conductive part is closer to the bottom of the heating pot body than the second conductive part, the first conductive part extends along the circumference of the heating pot body, and along the circumference of the heating pot body, the size of the second conductive part is smaller than the size of the first conductive part.

[0013] Thus, such a configuration can increase the thermal resistance of the first electrode, reduce heat transfer upward from the first conductive part, and reduce the temperature rise of the first electrode.

[0014] In some embodiments, the first conductive portion surrounds the heating pot along the circumference of the heating pot to form a closed ring.

[0015] In this way, when a magnetic field is provided at the electric arc, the first conductive portion is in a closed ring shape, which is conducive to the magnetic field driving the electric arc to rotate, and the electric arc is continuous along the rotation trajectory of the circumference of the heating pot body.

[0016] In some embodiments, the first electrode also includes a third conductive part, the second conductive part connects the first conductive part and the third conductive part, the second conductive part is closer to the bottom of the heating pot body than the third conductive part, the third conductive part extends along the circumference of the heating pot body, and a fracture is formed on the third conductive part so that the third conductive part includes at least two segments distributed at intervals along the circumference of the heating pot body.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] In some embodiments, the second electrode is fixed to the outer surface of the heating pot.

[0021] In this way, the electric 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.

[0022] In some embodiments, the second electrode is fixed at the center of the bottom of the heating pot.

[0023] 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.

[0024] 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 at least partially disposed on the side wall.

[0025] 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.

[0026] In some embodiments, the shortest connection line between the first electrode and the second electrode passes through the bottom of the heating pot.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] In some embodiments, the heating pot body comprises 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.

[0031] 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.

[0032] The aerosol generating device according to the embodiment of the present application comprises a housing and a 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 comprises a conductive component, which abuts against the first electrode and is used to supply power to the first electrode.

[0036] In this way, the conductive component is in contact with the first electrode to facilitate the replacement of the first electrode and the heating pot body.

[0059] See also Figure 1 and Figure 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 aerosol 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. 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, and the aerosol inhaled into the user's respiratory system can be used for various purposes such as food, medicine, health care, entertainment, etc.

[0060] See also Figure 2-Figure 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 receiving cavity 101 for receiving 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 receiving cavity 101.

[0061] The aerosol generating device 1000 of the embodiment of the present application fixes the first electrode 110 on the outer surface 103 of the heating pot body 10, and the first electrode 110 and the heating pot body 10 form an integral heating component 100, so that after a period of use, the first electrode 110 and the heating pot body 10 can be taken out and replaced together, which improves the restriction conditions for replacing the heating pot body 10, avoids the arbitrary replacement of non-standard heating pot bodies, and ensures the suction taste and safety of use. In addition, the first electrode 110 and the heating pot body 10 are replaced together, so that the aerosol generating device 1000 is not easily affected by electrode loss in normal operation, and the reliability and cleaning convenience of the aerosol generating device 1000 are improved. Furthermore, the first electrode 110 and the heating pot body 10 are formed into a whole, which is conducive to the efficient use of thermal efficiency. Further, the critical point of replacement of the heating pot body 10 can be determined by measuring the change in the resistance value of the first electrode 110, so as to unify the replacement standard.

[0062] Specifically, the aerosol-forming matrix 20 in the accommodating cavity 101 may be in a fully solid or semi-solid state. For example, the aerosol-forming matrix 20 may be a paste or a gel, and the paste or gel with high humidity may be applied to the inner wall surface of the pot bottom 11 or filled in the pot bottom 11. For another example, the completely solid aerosol-forming matrix 20 may be in a relatively fine block or sheet shape. The aerosol-forming matrix 20 as a whole may have a certain fluidity, and the aerosol-forming matrix 20 may be placed in the accommodating cavity 101 and may be deposited on the bottom of the heating pot body 10.

[0063] The heating pot body 10 has an opening 102, one end of which forms the opening 102 is the top of the heating pot body 10, and the pot bottom 11 is opposite to the top and closes the bottom of the heating pot body 10. In this application, the direction from the opening 102 of the heating pot body 10 to the pot bottom 11 is defined as the direction from top to bottom, and the direction from the center of the opening 102 to the geometric center of the pot bottom 11 is defined as the axial direction of the heating pot body 10, that is, the vertical direction of the heating component 100. The transverse direction of the heating component 100 is perpendicular to the vertical direction, and the shape of the cross section of the inner and outer contours of the heating pot body 10 includes but is not limited to a circle, an ellipse, a regular quadrilateral, a rectangle, a polygon, and other polygons with rounded corners or curved edges. Exemplarily, this application is described with the shape of the cross section of the inner and outer contours of the heating pot body 10 as a circle, and the direction of the circumference of the cross section of the outer contour is the circumference of the heating pot body 10. The heating pot body 10 can be made of a material with good heat resistance, for example, the heating pot body 10 is made of quartz, ceramic or heat-resistant glass.

[0064] The first electrode 110 is in the form of a film, and the first electrode 110 is attached to the outer surface 103 of the heating pot body 10. The first electrode 110 can be formed on the outer surface 103 of the heating pot body 10 by screen printing. The first electrode 110 can be made of a material with good conductivity and heat resistance, for example, the first electrode 110 can be made of one or more of copper and copper alloys, tungsten and tungsten alloys, graphite, and carbon fiber. The first electrode 110 can also use an adhesive to strengthen the connection strength between the first electrode 110 and the heating pot body 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, the number of the first electrodes 110 is two, and the two first electrodes 110 can be respectively arranged at the center of the pot bottom 11 and between the pot bottom 11 and the opening 102, and the two first electrodes 110 are opposite to each other along the extension direction of the outer surface 103, and can discharge and generate an arc at the position where the distance between the two first electrodes 110 is closest. 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 are opposite to 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 conduct 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 polarity voltage, and discharge with an electrode conducting another polarity voltage to generate an arc.

[0069] In some embodiments, the pot 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 is 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 is 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 may be a round bottom 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 connected by an arc. The pot bottom 11 may also be a flat surface at the center, and transitionally connected to the side wall 12 by an arc connection surface. In this embodiment, the curvature radius 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 of heat transfer and a relatively large contact area with the electric arc.

[0074] See also Figure 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 heating pot body 10, and can simplify the replacement operation of the heating component 100.

[0076] Specifically, the body 13 includes a pot bottom 11 and a side wall 12, and the pot bottom 11 and the side wall 12 define a receiving cavity 101. The side wall 12 can extend along the axial direction of the heating pot body 10, connecting the pot bottom 11 with an opening 102 at the top. The aerosol-forming substrate 20 can enter the receiving cavity 101 through the opening 102, and can be applied on the pot bottom 11 and the side wall 12, can be poured or injected into the receiving cavity 101, or can be directly placed on the pot bottom 11 by a handheld or transfer tool.

[0077] The opening 102 may be defined by the inner circular surface of the top of the body 13, and the side wall 12 extends toward the outer periphery along the radial direction of the body 13 at the opening 102 to form a flange 14. The distance that the flange 14 extends in the radial direction of the heating pot body 10 is the length of the flange 14, and the length of the flange 14 may be greater than the thickness of the side wall 12, and the length of the flange 14 is usually set to be significantly smaller than the diameter of the body 13. The thickness of the flange 14 may be consistent with the thickness of the side wall 12, or may be slightly greater than or slightly less than the thickness of the side wall 12. In some embodiments, the direction in which the flange 14 may extend toward the outer periphery may be the radial direction of the body 13.

[0078] See also Figure 2 and Figure 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, with high space utilization, which is conducive to the miniaturization of the heating component 100.

[0080] Specifically, the pot bottom surface 1031 may be a flat surface, or may include a flat surface and an arc transition surface, and the flat pot bottom surface 1031 may extend along the radial direction of the heating pot body 10. The pot bottom surface 1031 may also be an arc surface, and the normal direction of the pot bottom surface 1031 with curvature may be consistent with the axial direction of the heating pot body 10. The outer peripheral surface 1032 is connected 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 may be attached to the outer peripheral surface 1032 and arranged close to the pot bottom surface 1031.

[0081] Please continue reading Figure 2 and Figure 3In 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 body 10 than the second conductive portion 112, and the first conductive portion 111 extends along the circumference of the heating pot body 10. Along the circumference of the heating pot body 10, the size of the second conductive portion 112 is smaller than the size of the first conductive portion 111.

[0082] In some embodiments, the first electrode 110 also 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 be in various shapes with different parts and combined in various forms to form various patterns on the outer peripheral surface 1032, so as to control the direction of the current and the position of the discharge end, and affect the heat dissipation path. The first conductive part 111 and the third conductive part 113 can both be annular, surround the heating pot body 10 along the circumference of the heating pot body 10, and be spaced at a predetermined distance along the axial direction of the heating pot body 10. The first conductive part 111 is closer to the pot bottom 11 than the third conductive part 113, and the discharge end of the first electrode 110 forming an arc is located at the first conductive part 111.

[0085] The second conductive part 112 is located on the outer circumferential surface 1032 between the first conductive part 111 and the third conductive part 113, with one end connected to the first conductive part 111 and the other end connected to the third conductive part 113. Each first conductive part 111 and the third conductive part 113 are connected by at least one second conductive part 112. Along the circumference of the heating pot body 10, the size of the second conductive part 112 is smaller than the size of the first conductive part 111, and can also be smaller than the size of the third conductive part 113. The second conductive part 112 can be in a strip shape and can extend between the first conductive part 111 and the third conductive part 113 along a straight path or a curved path. The extension direction of the second conductive part 112 can be formed at a certain angle with the circumference of the heating pot body 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] For example, Figure 3 As shown, the second conductive portion 112 extends in a direction perpendicular to the circumference of the heating pot body 10 on the outer peripheral surface 1032 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 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, a magnetic part (not shown) may be provided in the aerosol generating device 1000, and the magnetic flux component of the magnetic field formed by the magnetic part (not shown) perpendicular to the arc can drive the arc to rotate around the heating pot body 10. The first conductive part 111 is in a closed ring shape, which can be a circular ring, an elliptical ring, a ring with multiple sections of different curvatures, etc. The first conductive part 111 surrounds the outer surface 103 along the circumference of the heating pot body 10 for at least one circle, and the first conductive part 111 extends continuously along the circumference of the heating pot body 10. The formed arc can rotate continuously during the process of rotating around the heating pot body 10, and it is not easy to break the arc, and the heating efficiency is high.

[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 body 10 along the circumference of the heating pot body 10. Accordingly, the arc will be broken in a very short time, and the broken arc is not visible to the naked eye.

[0091] See also Figure 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 sections spaced apart from each other along the circumference of the heating pot body 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 part 113 forms a fracture 1130, and the fracture 1130 can be a sub-conductive part 1131 that separates the third conductive part 113 into two semicircular rings. The sub-conductive parts 1131 extend along the circumference of the heating pot body 10 and are spaced from each other. The first electrode 110 is applied with a breakdown voltage, which can be connected to an external power supply through the third conductive part 113. The two sub-conductive parts 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 a voltage or resistance value change reaching 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 the change in 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 at the first conductive portion 111, and 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 value of the first electrode 110 after ablation. The third conductive portion 113 surrounds the circumference of the heating pot body 10, and the length of the third conductive portion 113 is relatively long, which can increase the basic resistance value or voltage of the detection circuit. Such a design also raises the product threshold and has a certain anti-wildcarding effect.

[0095] See also Figure 3-Figure 5 In some embodiments, the heating component 100 includes a second electrode 120 located outside the accommodating cavity 101, and 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, and the first electrode 110 and the second electrode 120 are connected to one of the cathode and the anode, respectively. The first electrode 110 and the second electrode 120 are arranged at intervals, and a gap is formed between the first electrode 110 and the second electrode 120, and there is a gas such as air in the gap. Arc discharge is a gas discharge phenomenon, which is a process in which the gas in the gap between the first electrode 110 and the second electrode 120 is ionized to form plasma under the action of a strong electric field, that is, an arc. The generation of the arc is accompanied by dazzling brilliance 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, which can quickly heat the aerosol-forming matrix 20 in the accommodating cavity 101 and atomize it to form an aerosol. The heating pot 10 and the first electrode 110 quickly heat up during the arc generation process, and heat can be transferred to the aerosol-forming matrix 20 by heat transfer and heat radiation.

[0098] In some embodiments, the number of the first electrode 110 is one. The first electrode 110 may be a first electrode 110 extending along the circumference of the heating pot body 10 on the outer peripheral surface 1032 of the heating pot body 10 to form a ring-shaped first electrode 110. The second electrode 120 may be arranged to face the center of the pot bottom surface 1031, and the first electrode 110 is located above the second electrode 120. An arc is generated by discharge between the second electrode 120 and the end of the first electrode 110 that is closest to it.

[0099] See also Figure 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 improve 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 by a structural member. The second electrode 120 can be fixed to the bottom surface 1031 or the outer peripheral surface 1032 of the pot, and is spaced a certain distance from the first electrode 110 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, and a strong electric field is formed on the outer surface 103 between the first electrode 110 and the second electrode 120 when power is turned on, so that an arc is formed on the outer surface 103 of the heating pot body 10.

[0102] See also Figure 3-Figure 5In 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] like Figure 3 As shown, in some embodiments, the second electrode 120 is in the form of a film and is formed at the center of the pot bottom surface 1031 by a printing process. Figure 5 As shown, in other embodiments, the second electrode 120 may be in the shape of a disk and may 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 at the outer peripheral surface 1032 and may partially extend to the arc surface of the pot bottom 11. When the first electrode 110 and the second electrode 120 are energized, they may be connected along the Figure 4 Middle BB connection or Figure 5 The path indicated by the CC line generates an arc, and the arc can cover the entire pot bottom surface 1031 , which is beneficial to improving the heat transfer efficiency from the arc to the heating pot body 10 .

[0105] See also 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] In this way, by arranging the first electrode 110 and the second electrode 120 on the side wall 12 , the insulation can be strengthened, and the discharge ends 140 are arranged at intervals 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 side wall 12 define a receiving cavity 101. The side wall 12 may surround the central axis of the heating pot body 10, and extend along the axial direction of the heating pot body 10 to connect the pot bottom 11 and the opening 102. The thickness of the pot bottom 11 and the side wall 12 may be equal, or the thickness range of the pot bottom 11 and the side wall 12 may be the same. The thickness of the pot bottom 11 and the side wall 12 may also be inconsistent.

[0108] In this embodiment, the pot bottom 11 can be a round bottom structure or a flat bottom structure. The outer contour of the heating pot body 10 is circular, oval, square, olive, racetrack or other polygons with curved edges. Exemplarily, 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 5mm to 20mm (including the end points), and the diameter of the outer peripheral surface 1032 of the side wall 12 can be regarded as 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 part 130 of the first electrode 110 and the second electrode 120 can be evenly arranged on the side wall 12, and the portion of the conductive part 130 connected to the discharge end 140 can fit or contact 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 against the side wall 12 near the bottom 11 of the pot.

[0110] The first electrode 110 and the second electrode 120 are arranged in pairs, and the number of the first electrode 110 and the second electrode 120 can be one pair, two pairs, three pairs, three pairs or more. The multiple pairs of the first electrode 110 and the second electrode 120 can be distributed at intervals along the circumference of the heating pot body 10. Further, the multiple pairs of the first electrode 110 and the second electrode 120 can be evenly distributed on the side wall 12 along the circumference of the heating pot body 10. The shortest connecting line of each pair of the first electrode 110 and the second electrode 120 passes through the center of the pot bottom 11 of the heating pot body 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 body 10 .

[0112] Thus, 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 the first electrode 110 and the second electrode 120 will discharge between the two ends with the shortest distance when power is supplied. To ensure that the arc is generated between the discharge ends 140 of the first electrode 110 and the second electrode 120, it is necessary to set the connection line between the discharge ends 140 of the first electrode 110 and the second electrode 120 as the shortest connection line. It should also be noted that the shortest connection line refers to the shortest connection line of the discharge ends 140 in the air medium, and the shortest connection line will not pass through the wall of the heating pot body 10. It can also be said that the shortest connection line is the shortest line segment between the first electrode 110 and the second electrode 120 on the outer surface 103 of the heating pot body 10. For example, Fig.11 In the embodiment shown, the MM line is the shortest line between the first electrode 110 and the second electrode 120, and the arc is generated on the MM line. Fig.12 In the embodiment shown, NN is the shortest line between the first electrode 110 and the second electrode 120, and the arc is generated on the NN line. The MM line and the NN line are both line segments on the pan bottom surface 1031.

[0114] In some embodiments, the pot bottom 11 is a round bottom structure, and the shortest connection line between the first electrode 110 and the second electrode 120 passes through the pot bottom 11 of the heating pot body 10. Fig.11The 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 line connecting the discharge end 140 through the pot bottom 11. For example, Fig.10 The LL line shown is a line connecting the discharge ends 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 line is less than the length of the LL line. The discharge ends 140 of the first electrode 110 and the second electrode 120 are 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] See also Fig.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, the first electrode 110 and the second electrode 120, whose discharge end 140 discharges to form an arc when energized, form an electrode pair, and the electrode pair is arranged along the radial direction of the heating pot body 10, and the first electrode 110 and the second electrode 120 are distributed at both ends of the same radial direction of the heating pot body 10. As described above, the shortest connecting line of the first electrode 110 and the second electrode 120 is the shortest connecting 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 the first electrode 110 and the second electrode 120 are energized, they discharge along the shortest connecting line NN to generate an arc, and the shortest connecting line NN passes through the center of the pot bottom 11, so that the arc can be generated at the center of the pot bottom 11, or formed near the center of the pot bottom 11, or the formed arc can pass through the center of the pot bottom surface 1031.

[0118] See also Figure 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, and the thickness D of the side wall 12 ranges from 0.5 mm to 1.0 mm (inclusive). In some embodiments, the minimum thickness d of the pot bottom 11 ranges from 0.3 mm to 0.8 mm (inclusive).

[0119] In this way, by setting the thickness of the bottom and the 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 side wall 12 may be formed around the central axis of the heating pot body 10, and the side wall 12 may be of uniform thickness, and the thickness D of the side wall 12 may also be of gradient or slope variation. The side wall 12 may also be of uniform thickness over a large area, with a local wall thickness reduced or increased. Exemplarily, the thickness D of the side wall 12 may be 0.5 mm-1.0 mm, 0.6 mm-0.9 mm, 0.63 mm-0.88 mm, 0.7 mm-0.9 mm, 0.75 mm-0.8 mm, etc. For another example, the thickness D of the side wall 12 may be 0.5 mm, 0.54 mm, 0.65 mm, 0.72 mm, 0.81 mm, 0.97 mm, 1.0 mm.

[0121] In some embodiments, the side wall 12 and the pot bottom 11 may be of equal thickness. In some other embodiments, the thickness H of the pot bottom 11 may be less than the thickness D of the side wall 12, and the thickness of the connection between the pot bottom 11 and the side wall 12 gradually decreases in thickness. The overall thickness H of the pot bottom 11 may be consistent. The thickness of the pot bottom 11 may be locally thinned to reduce the thermal resistance between the arc and the aerosol-forming matrix 20. At locations where the thickness of the pot bottom 11 is not equal, the thickness may change smoothly to avoid a step difference between the inner and outer surfaces 103 of the heating pot body 10. Exemplarily, the thickness d at the thinnest part of the pot bottom 11 may range from 0.3mm to 0.8mm, 0.4mm to 0.7mm, 0.45mm to 0.6mm, 0.5mm to 0.58mm, etc. For another example, the minimum wall thickness d of the pot bottom 11 may be 0.3mm, 0.37mm, 0.46mm, 0.57mm, 0.68mm, 0.75mm, 0.8mm.

[0122] Please refer again Figure 2-Figure 4 The heating component 100 of the embodiment of the present application further includes a sealing member 30 , which 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 the 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 elasticity, such as rubber, silicone, resin, etc. In some embodiments, the seal 30 can be made into a rubber ring or a rubber strip, and is 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 coated on the heating pot body 10 with sealing glue and cured. The seal 30 can be fixed on 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] See also Figure 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, and the aerosol can overflow from the opening 102 for inhalation. The sealing member 30 can be the edge of the heating pot body 10 sleeved at the opening 102. When the heating pot body 10 is loaded into the heating module or the aerosol generating device 1000, the sealing member 30 can seal the accommodating chamber 101 at the opening 102 to reduce the diffusion of the aerosol inside 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 to the accommodating chamber 101 in the form of heat transfer and heat radiation through the first electrode 110, the second electrode 120, and the heating pot body 10. The inside and outside of the accommodating chamber 101 can be sealed and isolated by the sealing member 30 at the opening 102, so as to prevent the odor during the discharge process from entering the accommodating chamber 101, prevent the arc from directly contacting the aerosol and / or the aerosol-forming matrix 20, and ensure the purity of the aerosol-forming matrix 20 and the quality of the aerosol. In addition, the sealing member 30 disposed at the opening 102 is also conducive to the heat insulation of the top of the heating pot body 10.

[0128] Please continue reading Figure 4 In some embodiments, the flange 14 is formed with an opening 102 , and the seal 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 from the top of the side wall 12 to a direction away from the accommodating cavity 101 along the circumference of the heating pot body 10. As described above, the inner circle of the side wall 12 at the top, that is, the inner circle of the flange 14, defines an opening 102. The edge of the flange 14 is away from the accommodating cavity 101 relative to the side wall 12, and the seal 30 wraps the edge of the flange 14 from the outer periphery of the opening 102, and the seal 30 fits tightly with the flange 14. The heating pot body 10 can be assembled by the angle formed by the flange 14 and the side wall 12, and the seal 30 wraps the edge of the flange 14, which can play a certain buffering and bonding role during assembly.

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

[0132] See also Figure 3 and Figure 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 peripheral 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 sealing member 30 can be more closely matched to the shape of the sealed portion of the heating pot body 10, thereby increasing the contact area and obtaining a better sealing effect.

[0134] Specifically, the first sealing portion 31 can extend outward from the inner circumference of the opening 102, and closely adhere 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 closely adheres 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 is closely fitted to 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 are different in position and shape, and the first sealing portion 31 and the second sealing portion 32 can be integrally formed as one element.

[0135] Please continue reading Figure 4 and Figure 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 surface of the first sealing portion 31 wrapped below the flange 14 on one side facing away from the flange 14 is the first sealing surface 311. The extension direction of the first sealing surface 311 may be consistent with the flange 14. For example, the flange 14 extends outward along the circumference of the heating pot body 10. The first sealing surface 311 extends along the circumference of the heating pot body 10 on the side of the flange 14 facing the bottom of the heating pot body 10. The first sealing surface 311 may form a certain angle with the axial direction of the heating pot body 10. The second sealing surface 321 is the surface of the second sealing portion 32 on one side facing away from the side wall 12.

[0138] In some embodiments, the heating pot body 10 is installed in the housing 200 from top to bottom, and the sealing member 30 wraps the flange 14 and abuts 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 a 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 extending along the circumferential direction of the heating pot body 10 may be significantly smaller than the width of the second sealing surface 321. When the housing 200 and the sealing member 30 are pressed against each other, the sealing protrusion 322 may be deformed to a certain extent along the protruding direction, thereby increasing the contact area between the second sealing surface 321 and the housing 200.

[0142] See also Figure 6 and Figure 7 The aerosol generating device 1000 of the embodiment of the present application includes a housing 200 and a heating component 100 of any of the above-mentioned embodiments, and the heating pot body 10 is at least partially accommodated in the housing 200 .

[0143] In this way, the heating pot body 10 is accommodated in the housing 200 , and the housing 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 body 10 is accommodated in the shell 200, and the flange 14 can at least partially extend out of the shell 200. The heating pot body 10 is detachably connected to the shell 200. When the heating pot body 10 is replaced, the sealing member 30 and the first electrode 110 can be removed from the shell 200 together with the heating pot body 10.

[0145] See also Figure 7 In some embodiments, the seal 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 seal 30 to prevent discharge or heat release odor from mixing into the aerosol.

[0147] Specifically, the heating pot body 10 is accommodated in the shell 200, and the side wall 12 and the pot bottom 11 are spaced a certain distance from the wall surface of the shell 200 to form a gap. The shell 200 can 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 the seal 30, and the first sealing surface 311 and the second sealing surface 321 are extruded assembly surfaces. The seal 30 is wrapped outside the flange 14, and the first sealing surface 311 and the second sealing surface 321 are in close contact with the shell 200 to seal the gap between the shell 200 and the heating pot body 10. The electric arc is generated between the heating pot body 10 and the shell 200, and the aerosol is generated in the accommodating cavity 101. The accommodating cavity 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 body 200 abut may be on the outer peripheral surface 1032 . In this embodiment, the seal 30 is disposed at the position where the heating pot body 10 and the shell body 200 abut to seal the gap between the shell body 200 and the heating pot body 10 .

[0149] See also Figure 6 and Figure 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 the top of the heating component 100, and can be extruded and assembled with the heating pot body 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, so that the aerosol generated in the accommodating cavity 101 overflows from the opening 102 and is inhaled through the nozzle assembly 300.

[0152] See also Figure 7 and Figure 8In some embodiments, the seal 30 wraps the flange 14, the seal 30 and the heating pot body 10 are integrated, the heating pot body 10 abuts against the shell 200 through the flange 14, the first sealing surface 311 abuts against the top of the shell, the first sealing portion 31 is pressed against the nozzle assembly 300 on the side away from the first sealing surface 311, and the nozzle assembly 300, the heating pot body 10 and the shell 2000 are extruded and assembled by the seal 30, with stable support, high reliability, and good thermal insulation performance. The nozzle assembly 300 and the heating pot body 10, and the heating pot body 10 and the shell 200 can be detachably connected, and the heating pot body 10 is easy to replace.

[0153] See also 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 the heat loss in the insulating space 401, thereby improving the heating efficiency and the heating rate.

[0155] Specifically, the insulating and heat-insulating body 400 can be arranged below the heating pot body 10, and the insulating and heat-insulating body 400 can cover part of the side wall 12 and cover the pot bottom 11. The inner wall surface of the insulating and heat-insulating body 400 and the pot bottom surface 1031 define an insulating space 401, and the insulating space 401 and the accommodating cavity 101 can be separated by the pot bottom 11. The first electrode 110 can partially extend into the insulating space 401, and the second electrode 120 can be arranged on the pot bottom 11 or the insulating and heat-insulating body 400. When the first electrode 110 and the second electrode 120 are energized, they discharge in the insulating space 401 below the pot bottom 11 to generate an arc, and the odor and electric sparks during the discharge can be isolated by the insulating and heat-insulating body 400.

[0156] The insulating and heat-insulating body 400 can be made of insulating materials with good heat resistance, such as quartz, heat-resistant glass and the like. The heating pot body 10 transfers the arc heat to the accommodating cavity 101 to heat the aerosol-forming matrix 20. The insulating and heat-insulating body 400 isolates the arc, which can prevent high-voltage discharge from damaging other structural parts and reduce the transmission of arc heat to other structural parts.

[0157] See also Figure 7 and Fig. 9 In some embodiments, the aerosol generating device 1000 includes a conductive component 500 , which abuts against the first electrode 110 and is used 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 facilitate 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 ends of the transformer (not shown), and the other output end 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 ends 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 through the sub-conductive portion 1131.

[0160] The first electrode 110 is in contact with the conductive component 500 and is connected at the upper end of the first electrode 110 along the axial direction of the heating pot body 10 to prevent the arc from breaking through 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 body 10, the sealing member 30 is formed integrally with the heating pot body 10, the heating component 100 is detachably connected to the housing 200, and the first electrode 110, the sealing member 30 and the heating pot body 10 can be removed from the aerosol generating device 1000 and replaced together after being used for a period of time, which is convenient for cleaning and maintenance of the aerosol generating device 1000. The replacement frequency of the first electrode 110 and the sealing member 30 is increased, which reduces the failure caused by the ablation of the first electrode 110 or the aging of the sealing member 30, and improves the reliability and service life of the aerosol generating device 1000.
