[0049] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0050] It should be understood that the terms "front", "rear", "left", "right", "upper", "lower", "first", "second", etc. are only for the convenience of describing the technical solution of the present invention, and do not indicate that the devices or elements referred to must have special differences, and therefore cannot be understood as limitations on the present invention. It should be noted that when a piece is considered to be "connected" to another piece, it can be directly connected to the other piece or there may be a central piece at the same time. Unless otherwise defined, all technical and scientific terms used in this document have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0051] Figure 1 and Figure 2 An electronic atomization device in some embodiments of the present invention is shown, which can be used for users to inhale aerosols, and may include an atomizer 1 and a battery device 2 that cooperates with the atomizer 1. The atomizer 1 can be used to store and heat atomized liquid aerosol-generating substrates such as liquid medicine, and to guide the aerosol out. The battery device 2 can be used to power the atomizer 1. In some embodiments, the atomizer 1 and the battery device 2 can both be cylindrical, and the two are mechanically and electrically connected together along the axial direction. In some embodiments, the atomizer 1 and the battery device 2 are detachably connected together by threaded connection. It can be understood that the atomizer 1 and the battery device 2 are not limited to being connected by threading, and they can also be detachably connected together by magnetic attraction. It can also be understood that the atomizer 1 and the battery device 2 are not limited to being cylindrical, and they can also be cylindrical with an elliptical, racetrack-shaped or irregular cross-section.

[0052] like Figures 3 to 5 As shown, in some embodiments, the atomizer 1 may include a cylindrical atomizing body 10 located at the bottom and a nozzle assembly 20 axially connected to the upper end of the atomizing body 10. The atomizing body 10 is used to store and heat the atomized liquid aerosol generating matrix, and the nozzle assembly 20 is used to block the liquid aerosol generating matrix in the atomizing body 10 and guide the aerosol out. In some embodiments, the nozzle assembly 20 is embedded in the upper end of the atomizing body 10 in a tight fit to facilitate the injection of the liquid aerosol generating matrix into the atomizing body 10. The nozzle assembly 20 can be detachably connected to the upper end of the atomizing body 10. At this time, the liquid aerosol generating matrix can be repeatedly added to increase the service life of the atomizer 1. For some disposable atomizers 1, the nozzle assembly 20 and the atomizing body 10 may also be non-detachable, that is, once the two are connected, they are locked and cannot be separated without destroying the existing structure. In addition, even a reusable atomizer can be an integrated structure by adding a liquid injector, such as Fig.16This is the case with the atomizer 1c shown.

[0053] Read also Figure 6 and Figure 7 In some embodiments, the atomizing body 10 may include a base 11, a ventilation pipe 12, a shell 13, an atomizing assembly 14, an electrode column 15, an insulating sealing ring 16, a first electrode claw 17 and a second electrode claw 18 which are coaxially assembled together.

[0054] In some embodiments, the base 11 may be cylindrical and conductive. In some embodiments, the ventilation duct 12 may also be conductive, and is longitudinally embedded in the upper part of the base 11 and electrically connected to the base 11; the ventilation duct 12 defines a columnar atomization chamber 120. In some embodiments, the shell 13 may be cylindrical, and is longitudinally sleeved on the upper part of the base 11 and surrounds the ventilation duct 12; an annular liquid storage chamber 130 is defined between the inner wall surface of the shell 13 and the outer wall surface of the ventilation duct 12. A liquid inlet hole 122 that connects the liquid storage chamber 130 with the atomization chamber 120 may also be formed on the ventilation duct 12. In some embodiments, the atomization assembly 14 may be cylindrical and longitudinally arranged in the atomization chamber 120; a longitudinally through-going air flow channel 140 may be formed in the middle of the atomization assembly 14. The electrode column 15 is longitudinally penetrated in the lower part of the base 11 and is electrically insulated from the base 11; specifically, an insulating sealing ring 16 is longitudinally provided in the lower part of the base 11, and the electrode column 15 is penetrated in the insulating sealing ring 16, so as to achieve an insulating and sealed connection with the base 11. One end of the first electrode claw 17 is fixed to the inner wall of the ventilation duct 12 and is electrically connected to the ventilation duct 12, and the other end is elastically contacted with the upper end of the atomizer assembly 14, thereby electrically connecting the upper end of the atomizer assembly 14 to the ventilation duct 12. One end of the second electrode claw 18 is fixed to the electrode column 15 and is electrically connected to the electrode column 15, and the other end is elastically contacted with the lower end of the atomizer assembly 14, thereby electrically connecting the lower end of the atomizer assembly 14 to the electrode column 15.

[0055] In some embodiments, the electrode column 15 is used to be electrically connected to the positive electrode of the battery device 2, and the base 11 is used to be electrically connected to the negative electrode of the battery device 2, thereby forming an electrical circuit. After the current is allowed to come out from the positive electrode of the battery device 2, it passes through the electrode column 15 and the second electrode claw 18 in sequence, reaches the lower end of the atomizer assembly 14, penetrates the atomizer assembly 14 and heats the atomizer assembly 14, reaches the upper end of the atomizer assembly 14, and then passes through the first electrode claw 17, the ventilation pipe 12 and the base 11 in sequence before flowing back to the negative electrode of the battery device 2. It can be understood that in some embodiments, the electrode column 15 and the base 11 can also be electrically connected to the negative electrode and the positive electrode of the battery device 2 respectively. At this time, the direction of the current is opposite to the above direction.

[0056] For example Figure 6 and Figure 7As shown, in some embodiments, the base 11 may be integrally formed of metal materials, and may include a circular base 111, a first mounting cylinder 112 longitudinally disposed on the upper surface of the base 111, and a second mounting cylinder 113 longitudinally disposed on the bottom surface of the base 111. A through hole 1110 is longitudinally provided in the middle of the base 111, and the through hole 1110 connects the first mounting cylinder 112 and the second mounting cylinder 113. The outer wall surface of the second mounting cylinder 113 is formed with a thread structure 1131 for threading the upper end of the battery device 2, and the inner wall surface is formed with a mounting ring 1132 that matches the insulating seal ring 16.

[0057] In some embodiments, the ventilation duct 12 may be integrally formed of a metal material, and may include a first pipe section 121, a second pipe section 123 axially connected to the upper end of the first pipe section 121, and a third pipe section 125 axially connected to the lower end of the first pipe section 121, and the inner diameter and outer diameter of the third pipe section 125, the first pipe section 121, and the second pipe section 123 are all decreased in sequence. The first pipe section 121 defines the above-mentioned atomization chamber 120, and the above-mentioned liquid inlet holes 122 may be multiple and uniformly formed on the circumference of the side wall of the first pipe section 121. The inner wall surface of the second pipe section 123 near the first pipe section 123 may be provided with a retaining ring 1231 extending toward the central axis, which is used to provide an axial resistance force to the first electrode claw 17. The end surface of the retaining ring 1231 close to the first electrode claw 17 may be a plane perpendicular to the central axis of the second pipe section 123, and the end surface away from the first electrode claw 17 may be a trumpet-shaped conical surface. The outer diameter of the third pipe section 125 is adapted to the inner diameter of the first mounting tube 112, so that the third pipe section 125 is embedded in the first mounting tube 112 in the longitudinal direction and is tightly matched with the first mounting tube 112. The height of the third pipe section 125 is equivalent to the height of the first mounting tube 112. In some embodiments, in order to facilitate the embedding of the third pipe section 125 in the first mounting tube 112, the outer wall surface of the third pipe section 125 near the lower end is also inwardly formed with a guide portion 1251, and the outer diameter of the guide portion 125 is smaller than the first mounting tube 112.

[0058] In some embodiments, the housing 13 may be made of a transparent material, and its inner diameter is adapted to the outer diameter of the first mounting tube 112, so that the housing 13 can be sleeved on the first mounting tube 112 at the lower end along the axial direction and tightly fit with the first mounting tube 112. The upper end surface of the housing 13 may be slightly lower than the upper end surface of the second pipe segment 123, so as to better match the nozzle assembly 20. The inner wall surface of the housing 13 and the inner wall surfaces of the first pipe segment 121 and the second pipe segment 123 define the above-mentioned liquid storage cavity 130, and an annular liquid injection port 132 is formed between the upper end of the housing 13 and the upper end of the second pipe segment 123.

[0059] In some embodiments, the atomizer assembly 14 may include a longitudinally disposed cylindrical atomizer core 141 , a first sealing ring 142 sleeved on the upper end of the atomizer core 141 , and a second sealing ring 143 sleeved on the lower end of the atomizer core 141 .

[0060] The first sealing ring 142 may have an L-shaped cross section, and is used to seal the gap between the upper end of the atomizer core 141 and the upper end of the first pipe section 121. In some embodiments, the first sealing ring 142 may include a cylindrical first sealing portion 1421 and a circular second sealing portion 1423 connected to the upper end edge of the first sealing portion 1421, the first sealing portion 1421 is sleeved on the outer wall surface of the upper end of the atomizer core 141, and the second sealing portion 1423 covers the upper end surface of the atomizer core 141. The inner diameter of the second sealing portion 1423 is preferably larger than the aperture of the atomizer core 141, so that the first electrode claw 17 will not be blocked by the second sealing portion 1423 when it cooperates with the atomizer core 141.

[0061] The second sealing ring 143 may also have an L-shaped cross section, which is used to seal the gap between the lower end of the atomizer core 141 and the third pipe section 125. In some embodiments, the second sealing ring 143 may include a cylindrical third sealing portion 1431 and a circular fourth sealing portion 1433 connected to the lower end edge of the third sealing portion 1431, the third sealing portion 1431 is sleeved on the outer wall surface of the lower end of the atomizer core 141, and the fourth sealing portion 1433 covers the lower end surface of the atomizer core 141. The middle of the outer wall surface of the atomizer core 141 may face the liquid inlet hole 122. A central through hole 1410 is formed in the middle of the atomizer core 141. The inner diameter of the fourth sealing portion 1433 is preferably larger than the aperture of the atomizer core 141, so that the second electrode claw 18 will not be blocked by the fourth sealing portion 1433 when it cooperates with the atomizer core 141.

[0062] In some embodiments, the inner wall surface of the first sealing ring 142 is formed with a first ventilation groove 1420 in a labyrinth shape, and the first ventilation groove 1420 penetrates the inner wall surfaces of the first sealing part 1421 and the second sealing part 1423. The size of the first ventilation groove 1420 can be designed to be small enough to have a capillary force in the use state, and is used to connect the liquid storage chamber 130 with the air flow channel in the ventilation duct 12 when the liquid storage chamber 130 is under a large negative pressure, so as to achieve gas-liquid balance and prevent dry burning. In some embodiments, the second sealing ring 143 can also be provided with a second ventilation groove 1430 in a labyrinth shape on the inner wall surface, and the second ventilation groove 1430 penetrates the inner wall surfaces of the third sealing part 1431 and the fourth sealing part 1433, and has the same function as the first ventilation groove 1420. In some embodiments, the first sealing ring 142 and the second sealing ring 143 have the same structure, and the two can be used universally, so that it is convenient for automated installation and saves the mold opening cost of the sealing ring.

[0063] It can be understood that either the first sealing ring 142 or the second sealing ring 143 can be provided with a ventilation structure, and both have their own advantages and disadvantages. When only the first sealing ring 142 has a ventilation structure, if the first ventilation groove 1420 of the first sealing ring 142 leaks, part of the leaked liquid will flow downward from the upper end of the atomizer core 141, and will be absorbed by the atomizer core 141 and atomized again. When only the second sealing ring 143 has a ventilation structure, although the possible leaked liquid is easy to flow into the base 11, since the airflow direction in the airflow channel is from bottom to top, the air replenishment through the second sealing ring 143 is smoother. In some embodiments, the sealing silicone of the second sealing ring 143 at the lower end is thicker, that is, the distance from the surface of the second sealing ring 143 in contact with the atomizer core 141 to the surface in contact with the ventilation pipe 12 can better seal the lower end of the atomizer core 141 through interference fit, thereby avoiding leakage. When the two are compared, they are compared with the thickness of the corresponding part of the first sealing ring 142.

[0064] Read also Figure 8 In some embodiments, the atomizing core 141 may include a cylindrical porous body 1411, a heating body 1412 disposed on the inner wall of the porous body 1411, a first electrode 1413 disposed on the upper end of the inner wall of the porous body 1411 and electrically connected to the upper end of the heating body 1412, and a second electrode 1414 disposed on the lower end of the inner wall of the porous body 1411 and electrically connected to the lower end of the heating body 1412. In some embodiments, the porous body 1411 may be a porous ceramic, and may be a small-sized porous body 1411. In some embodiments, the length of such a small-sized porous body 1411 may be 0.8-1.2 cm, and the inner diameter may be 0.18-0.22 cm.

[0065] In some embodiments, the heating element 1412 may be made of nickel-chromium alloy, iron-chromium-aluminum alloy, silver-palladium alloy, etc., printed or sprayed on the inner surface of the porous body 1411, and then sintered to form the inner wall surface of the porous body 1411. It may include two long and thin circular heating circuits B arranged in parallel in the axial direction of the porous body 1411 and a connecting circuit C connecting the two in series. The length direction of the two heating circuits B extends along the inner wall surface of the porous body 1411 in the circumferential direction so that the whole is C-shaped. The heating element 1412 may also include an upper circuit D and a lower circuit A connected to the upper end and the lower end respectively, so as to be electrically connected to the first electrode 1413 and the second electrode 1414 respectively.

[0066] The first electrode 1413 and / or the second electrode 1414 can be made of materials such as silver and copper, and can be formed on the inner wall surface of the cylindrical porous body 1411 by coating / printing and sintering with silver paste or copper paste, and at least partially connected to the heating element 1412. In some embodiments, the first electrode 1413 and / or the second electrode 1414 can be C-shaped, which is usually first printed on the body of the porous body 1411 with the heating element 1412 slurry, and then the electrode slurry is printed or coated, and then sintered together. In some embodiments, the width of the notch of the first electrode 1413 can be smaller than the width of the conductive portion 173, so as to be in electrical contact with all the conductive portions 173 of the first electrode claw 17; the width of the notch of the second electrode 1414 can be smaller than the width of the conductive portion 183, so as to be electrically connected to all the conductive portions 183 of the second electrode claw 18. It is understandable that the heating element 1412 may also be made of a metal heating sheet in some embodiments, and the porous body 1411 is also limited to porous ceramic materials, and other suitable porous body materials may also be used. It is understandable that the first electrode 1413 and / or the second electrode 1414 are not limited to being distributed in a C-shaped manner at the end of the inner wall surface of the porous body 1411, and they may also be distributed on the entire circumference of the end of the inner wall surface of the porous body 1411, that is, in a ring shape.

[0067] The arrangement of the first electrode 1413 and / or the second electrode 1414 does not require opening holes in the porous body 1411 for threading wires, and the internal structure of the porous body 1411 is more complete, controllable and reliable, so the consistency of the product is well guaranteed. In addition, the use of wires can be avoided, reducing the manufacturing difficulty and production cost. This is even more obvious for the application of miniaturized porous bodies 1411.

[0068] In some embodiments, there are also many benefits to respectively arranging the first electrode 1413 and the second electrode 1414 at the two ends of the inner wall surface of the small-sized porous body 1411. Because the inner wall area of ​​the miniaturized porous body 1411 is very small, if two electrodes are arranged at one end, the area of ​​the two electrodes is too small to establish a stable electrical connection with the electrode connector, and short circuit problems are prone to occur. By arranging the first electrode 1413 and the second electrode 1414 at both ends, the deployment of the first electrode 1413 and the second electrode 1414 can be facilitated, and the area of ​​the first electrode 1413 and the second electrode 1414 can be larger to facilitate the establishment of a stable electrical connection with the electrode connector.

[0069] For example Figure 6 and Figure 7As shown, in some embodiments, the electrode column 15 includes a central hole 150 extending upward from the lower end surface, an air outlet 152 formed on the top side wall, and a slot 154 formed on the side wall surface, and the air outlet 152 is connected to the central hole 150 for air intake. The slot 154 is used to engage with the insulating seal ring 16. The outer wall surface of the insulating seal ring 16 forms a slot 160 for engaging with the mounting ring 1132 of the base 11.

[0070] In some embodiments, the first electrode claw 17 can be made of materials such as phosphor copper or 316 stainless steel, and a gold-plated layer can be provided on its surface. The first electrode claw 17 is preferably made of phosphor copper material, and the impedance of phosphor copper material is relatively small. The first electrode claw 17 may include a mounting portion 171 embedded in the inner wall surface of the second tube section 123, three extension portions 172 connected to the mounting portion 171, and three conductive portions 173 respectively connected to the three extension portions 172. Each extension portion 172 and the corresponding conductive portion 173 form an elastic conductive arm of the first electrode claw 17. It can be understood that the number of elastic conductive arms of the first electrode claw 17 is not limited to three, one or more than one is fine, and having multiple elastic conductive arms can make the electrical connection more reliable and the assembly more convenient.

[0071] In some embodiments, the mounting portion 171 may be cylindrical, and have a longitudinal cutout 1710 that passes through the two side edges. The existence of the cutout 1710 may cause deformation during installation to ensure that the mounting portion 171 is better fixed to the inner wall surface of the second pipe segment 123. Specifically, a trumpet-shaped guide surface 1210 is provided at the junction of the second pipe segment 123 and the first pipe segment 121. The guide surface 1210 applies a radially inward force to the mounting portion 171 of the first electrode claw 17 during the process of the first electrode claw 17 being inserted into the second pipe segment 123 along the axial direction, so that the cutout 1710 of the mounting portion 171 is closed, the outer diameter is reduced, and the mounting portion 171 can be inserted into the second pipe segment 123; after being installed in place, the mounting portion 171 provides a reaction force to the inner wall surface of the second pipe segment 123, so that it can be firmly fixed to the second pipe segment 123. It can be understood that the mounting portion 171 can also be integrated with the second pipe segment 123 in some embodiments. In some embodiments, the mounting portion 171 may be axially embedded into the upper end of the central through hole 1410 of the atomizer core 141 and elastically abutted and fixed to the first electrode 1413 , while the elastic conductive arm is extended to elastically contact the ventilation duct 12 .

[0072] In some embodiments, the extension portion 172 may be strip-shaped and have good elasticity. Starting from the mounting portion 171, it first bends and extends toward the central axis of the mounting portion 171 for a distance, and then extends in a direction away from the mounting portion 171 along the central axis parallel to the mounting portion 171, so as to provide space for the conductive portion 173 to bend in a direction away from the central axis of the mounting portion 171 and provide good elastic properties. The extension portion 172 preferably has two or more extension portions to ensure a more reliable electrical connection; when there are multiple extension portions 171, it is best to evenly distribute them on the lower side edge of the mounting portion 171 and extend downward. Specifically, the extension portion 172 first extends obliquely toward the central axis of the mounting portion 171 for a distance, and then extends in a direction away from the mounting portion 171 along the central axis parallel to the central axis. A conductive portion 173 is provided at the end of each extension portion 172 for elastic contact with the first electrode 1413 of the atomizer core 141. In some embodiments, the conductive part 173 may be spoon-shaped. Specifically, the conductive part 173 first extends obliquely in a direction away from the central axis of the mounting part 171, and then bends and extends obliquely in the direction of the central axis. The inclined surface of the spoon-shaped structure is inclined inward, and has a guiding function. The bottom arc transition of the spoon-shaped structure can better contact the first electrode 1413 of the atomizer core 141, and the first electrode 1413 will not be scratched during assembly. The vertical distance from the bottom of the conductive part 173 to the central axis is slightly larger than the radius of the central through hole 1410 of the atomizer core 141 at the location of the first electrode 1413, so that when the conductive part 173 is axially inserted into the central through hole 1410, since the conductive part 173 has an inclined surface inclined inward, the force exerted by the atomizer core 141 on the conductive part 173 has a component force in the direction of the central axis, so that the extension part 171 is elastically deformed in the direction of the central axis, and the conductive part 173 can be inserted. After the conductive portion 173 is inserted into the central through hole 1410 , the elastic force of the extending portion 171 enables the conductive portion 173 to maintain close contact with the first electrode 1413 .

[0073] In some embodiments, the second electrode claw 18 may be made of materials such as phosphor copper or 316 stainless steel, and a gold-plated layer may be provided on its surface. The second electrode claw 18 is preferably made of phosphor copper material, which has a relatively small impedance. The second electrode claw 18 may include a mounting portion 181 sleeved on the upper part of the electrode column 15, an extension portion 182 connected to the mounting portion 181, and a conductive portion 183 connected to the extension portion 182. In some embodiments, the mounting portion 181 may be cylindrical, and has a longitudinal fracture 1810 that passes through the two side edges. The presence of the fracture 1810 may cause deformation during installation to ensure that the mounting portion 181 is better fixed to the upper part of the electrode column 15. It can be understood that the mounting portion 181 may also be connected to the electrode column 15 in some embodiments. In some embodiments, the extension portion 182 may be strip-shaped and have good elasticity. The extension portion 182 preferably has two or more extension portions to ensure a more reliable electrical connection. When there are multiple extension portions 181, it is best to evenly distribute them on the lower side edge of the mounting portion 181 and extend downward. A conductive portion 183 is provided at the end of each extension portion 182 for elastically contacting the second electrode 1414 of the atomizer core 141. In some embodiments, the conductive portion 183 may be spoon-shaped, with the inclined surface of the spoon-shaped inclined inward and having a guiding function. The bottom arc of the spoon-shaped transition can better contact the second electrode 1414 of the atomizer core 141, and the second electrode 1414 will not be scratched during assembly. In some embodiments, the second electrode claw 18 may have the same structure as the first electrode claw 17, and the two can be used universally, so that the difficulty of assembly can be reduced and the cost can be reduced.

[0074] When assembling the atomizer body 10, the following steps may be used:

[0075] (1) providing a base 11, an electrode column 15, an insulating seal ring 16 and a second electrode claw 18, installing the electrode column 15 into the second installation tube 113 of the base 11 through the insulating seal ring 16, and then sleeve the second electrode claw 18 onto the top of the electrode column 15 to form a base assembly; at this time, the conductive portion 183 of the second electrode claw 18 extends upward;

[0076] (2) providing the ventilation duct 12 and the first electrode claw 17 as shown in the figure, and embedding the first electrode claw 17 into the second duct 123 of the ventilation duct 12, with the conductive portion 173 of the first electrode claw 17 extending downward;

[0077] (3) Providing an atomizer core 141, a first sealing ring 142, and a second sealing ring 143, and respectively sleeve the first sealing ring 142 and the second sealing ring 143 on the upper and lower ends of the atomizer core 141 to form an atomizer assembly 14;

[0078] (4) Insert the atomizer assembly 14 from bottom to top into the ventilation duct 12, so that the first electrode 1413 of the atomizer core 141 is in conductive contact with the conductive portion 173 of the first electrode claw 17, thereby achieving electrical connection between the first electrode 1413 of the atomizer core 141 and the ventilation duct 12, thereby forming a ventilation duct assembly;

[0079] (5) The ventilation duct assembly is inserted into the first mounting tube 112 at the top of the base assembly, so that the ventilation duct 12 and the base 11 are tightly matched and electrically connected. In addition, the conductive portion 183 of the second electrode claw 18 is in contact and conducts with the second electrode 1414 of the atomizer core 141;

[0080] (6) Provide a shell 13 and sleeve the shell 13 onto the outside of the first mounting tube 112 to complete the assembly of the atomizing body 10 .

[0081] In the above-mentioned assembly steps of the atomizing body 10, the first electrode claw 17 and the second electrode claw 18 realize quick electrical contact and conduction between the components, which is more convenient and quicker to operate than the related art through wire welding and other methods, and it is easier to realize the automatic assembly of the product. It can be understood that the serial numbers before the above-mentioned steps are only for the convenience of description and do not indicate the order of each step. For example, during the specific assembly, the ventilation duct assembly can also be constructed first, and then the base assembly can be constructed.

[0082] For example Figure 4 and Figure 5 As shown, in some embodiments, the nozzle assembly 20 may include an annular sealing portion 21 and a flat nozzle portion 22 connected to the annular sealing portion 21, and the annular sealing portion 21 is used to be embedded in the annular liquid injection port 132 at the upper end of the atomizing body 10. The nozzle portion 22 has a longitudinal air guide hole 220 in the middle, and the air guide hole 220 is used to communicate with the upper end of the second pipe section 123 of the ventilation pipe 12 to guide the mixture of aerosol and air.

[0083] The atomizer 1 is assembled. First, the liquid aerosol generating matrix is ​​injected into the liquid storage chamber 130 of the atomizing body 10 through the liquid injection port 132. After the liquid storage chamber 130 is filled, the suction nozzle assembly 20 is inserted into the liquid injection port 132 to close the liquid storage chamber 130, and the air guide hole 220 of the suction nozzle assembly 20 is connected to the ventilation duct 12. At this time, the liquid aerosol generating matrix reaches the vicinity of the atomizing core 144 through the liquid inlet hole 122, and the porous body 1411 of the atomizing core 141 absorbs the liquid aerosol generating matrix to the inner surface through capillary force and contacts the heating element 1412. When in use, the atomizing assembly 1 is installed on the battery device 2. When the user inhales through the suction nozzle 22, the outside air such as Figure 3As shown by the arrow X, the liquid enters through the central hole 150 of the electrode column 15, passes through the through hole 1110 of the base 11, enters the central through hole 1410 of the atomizer core 141, and then is discharged through the air guide hole 220 of the nozzle assembly 20. At the same time, the air switch (not shown) in the battery device 2 is turned on, driving the battery device 2 to supply power to the atomizer 1. The heating element 1412 of the atomizer core 141 is energized to generate heat, and the liquid aerosol-generating matrix on the inner surface of the porous body 1411 is heated and atomized to form an aerosol. The aerosol is mixed with the air flowing through the central through hole 1410 and is carried out by the airflow.

[0084] Figures 9 to 11 The atomizing body 10a in some embodiments of the present invention is shown, and the shell is omitted in the figure. The atomizing body 10a can be used as a substitute for the above-mentioned atomizing body 10. As shown in the figure, the atomizing body 10a may include a base 11a, a ventilation pipe 12a, an atomizing assembly 14a, an electrode column 15a, an insulating sealing ring 16a, a first electrode claw 17a and a second electrode claw 18a coaxially assembled together in some embodiments. The base 11a may be cylindrical and conductive in some embodiments. The ventilation pipe 12a may also be conductive in some embodiments, and it is longitudinally arranged on the upper part of the base 11a and electrically connected to the base 11a; the ventilation pipe 12a defines a columnar atomizing chamber 120a. A liquid inlet hole 122a that connects the liquid storage chamber with the atomizing chamber 120a may also be formed on the ventilation pipe 12a. In some embodiments, the atomizer assembly 14a may be cylindrical and arranged longitudinally in the atomizer chamber 120a; a longitudinally through-flow airflow channel 140a may be formed in the middle of the atomizer assembly 14a. The electrode column 15a is longitudinally arranged in the lower part of the base 11a and is electrically insulated from the base 11a; specifically, an insulating sealing ring 16a is longitudinally arranged in the lower part of the base 11a, and the electrode column 15a is further arranged in the insulating sealing ring 16a, thereby realizing an insulating and sealed connection with the base 11a. One end of the first electrode claw 17a is fixed to the inner wall of the ventilation duct 12a and is electrically connected to the ventilation duct 12a, and the other end is elastically in contact with the upper end of the atomizer assembly 14a, thereby electrically connecting the upper end of the atomizer assembly 14a to the ventilation duct 12a. One end of the second electrode claw 18a is embedded in the electrode column 15a and electrically connected to the electrode column 15a, and the other end is elastically in contact with the lower end of the atomizer assembly 14a to electrically connect the lower end of the atomizer assembly 14a to the electrode column 15a.

[0085] In some embodiments, the electrode column 15a is used to be electrically connected to the positive electrode of the battery device 2, and the base 11a is used to be electrically connected to the negative electrode of the battery device 2a, thereby forming an electrical circuit. After the current is allowed to come out through the positive electrode of the battery device 2a, it passes through the electrode column 15a and the second electrode claw 18a in sequence, reaches the lower end of the atomizer assembly 14a, penetrates the atomizer assembly 14a and makes the atomizer assembly 14a heat up, reaches the upper end of the atomizer assembly 14a, and then passes through the first electrode claw 17a, the ventilation pipe 12a and the base 11a in sequence before flowing back to the negative electrode of the battery device 2a. It can be understood that in some embodiments, the electrode column 15a and the base 11a can also be electrically connected to the negative electrode and the positive electrode of the battery device 2 respectively. At this time, the direction of the current is opposite to the above direction.

[0086] In some embodiments, the base 11a can be integrally formed of metal materials, and can include a circular base 111a and a second mounting cylinder 113a longitudinally arranged on the bottom surface of the base 111a. A through hole 1110a is longitudinally provided in the middle of the base 111a, and the through hole 1110a connects the first pipe section 121a of the ventilation pipe 12a with the second mounting cylinder 113a. The inner wall surface of the second mounting cylinder 113a is formed with a mounting ring 1132a that matches the insulating sealing ring 16a. An air inlet 1130a is also formed on the side wall of the second mounting cylinder 113a.

[0087] In some embodiments, the ventilation duct 12a may include a first pipe section 121a integrally formed with the base 11a and a second pipe section 123a axially embedded in the upper end of the first pipe section 121a and electrically connected to the first pipe section 121a. The first pipe section 121a defines the above-mentioned atomization chamber 120a, and the above-mentioned liquid inlet holes 122a may be multiple and uniformly formed on the circumference of the side wall of the first pipe section 121a. A retaining ring 1231a may be provided on the inner wall surface of the second pipe section 123a near the first pipe section 123, which is used to provide an axial resistance force to the first electrode claw 17a.

[0088] In some embodiments, the atomizer assembly 14a may include a longitudinally arranged cylindrical atomizer core 141a, a first sealing ring 142a sleeved on the upper end of the atomizer core 141a, and a second sealing ring 143a sleeved on the lower end of the atomizer core 141a. The first sealing ring 142a may have an L-shaped cross-section for sealing the gap between the upper end of the atomizer core 141a and the first pipe section 121a and the second pipe section 123a. The second sealing ring 143a may also have an L-shaped cross-section for sealing the gap between the lower end of the atomizer core 141a and the base 11a. The middle part of the outer wall surface of the atomizer core 141a may be directly opposite the liquid inlet hole 122a. In some embodiments, the first sealing ring 142a and the second sealing ring 143a may be of the same structure.

[0089] In some embodiments, the inner wall surface of the first sealing ring 142a is formed with a first ventilation groove 1420a in the shape of a labyrinth. The size of the first ventilation groove 1420a can be designed to be small enough to have a capillary force in the use state, and is used to connect the liquid storage chamber with the air flow channel in the ventilation duct 12a when the liquid storage chamber is under a large negative pressure, so as to achieve gas-liquid balance and prevent dry burning. In some embodiments, the second sealing ring 143a can also be provided with a second ventilation groove 1430a in the shape of a labyrinth on the inner wall surface, which has the same function as the first ventilation groove 1420a. It can be understood that the ventilation groove can be provided on either the first sealing ring 142a or the second sealing ring 143a. In some embodiments, the first sealing ring 142a can have the same structure as the second sealing ring 143a, and the two can be used interchangeably.

[0090] For example Fig.11 As shown, in some embodiments, the atomizer core 141a may include a cylindrical porous body 1411a, a heating element 1412a disposed on the inner wall surface of the porous body 1411a, a first electrode 1413a disposed at the upper end of the inner wall surface of the porous body 1411a and electrically connected to the upper end of the heating element 1412a, and a second electrode 1414a disposed at the lower end of the inner wall surface of the porous body 1411a and electrically connected to the lower end of the heating element 1412a. In some embodiments, the structure of the atomizer core 141a may be exactly the same as that of the atomizer core 141 described above, and both may be used interchangeably.

[0091] In some embodiments, the electrode column 15a includes a central hole 150a extending downward from the upper end surface. In some embodiments, the electrode column 15a may include a bottom wall 155a to block the central hole 150a so that the central hole 150a can contain the leaked liquid and prevent the leaked liquid from leaking to the outside. In some embodiments, a retaining ring 156a is further provided at the upper end of the inner wall surface of the central hole 150a to resist the second electrode claw 18a. The outer wall surface of the insulating sealing ring 16a forms a card groove 160a for engaging with the mounting ring 1132a of the base 11a.

[0092] In some embodiments, the first electrode claw 17a may be made of elastic metal material, and may include a mounting portion 171a embedded in the inner wall of the second tube segment 123a, an extension portion 172a connected to the mounting portion 171a, and a conductive portion 173a connected to the extension portion 172a. In some embodiments, the mounting portion 171a may be cylindrical, and has a longitudinal fracture 1710a that runs through the upper and lower edges. The existence of the fracture 1710a allows the mounting portion 171a to adapt to the error of the inner diameter size of the second tube segment 123a, thereby increasing applicability. In some embodiments, the extension portion 172a may be strip-shaped, and preferably has three or more extension portions 171a; the three or more extension portions 171a are uniformly connected to the lower side edge of the mounting portion 171a and extend downward. A conductive portion 173a is provided at the end of each extension portion 172a, which is used to elastically contact with the first electrode 1413a of the atomizer core 141a to achieve conductivity, thereby improving assembly efficiency. In some embodiments, the first electrode claw 17 a may have the same structure as the first connecting member 17 , and both may be used interchangeably.

[0093] In some embodiments, the second electrode claw 18a may have the same structure as the first electrode claw 17a, and may also be made of elastic metal material, and include a mounting portion 181a embedded in the central hole 150a of the electrode column 15a, an extension portion 182a connected to the mounting portion 181a, and a conductive portion 183a connected to the extension portion 182a. In some embodiments, the mounting portion 181a may be cylindrical, and have a longitudinal fracture 1810a that passes through the upper and lower side edges. The presence of the fracture 1810a allows the mounting portion 181a to adapt to the size error of the central hole 150a of the electrode column 15a, thereby increasing applicability. In some embodiments, the extension portion 182a may be strip-shaped, and preferably has three or more extension portions 181a; the three or more extension portions 181a are evenly connected to the lower side edge of the mounting portion 181a and extend downward. Each extension portion 182a has a conductive portion 183a disposed at its end for elastically contacting the second electrode 1414a of the atomizer core 141a to achieve electrical conduction, thereby improving assembly efficiency. In some embodiments, the second electrode claw 18a may have the same structure as the second connector 18, and both may be used interchangeably.

[0094] When assembling the atomizing body 10a, the following steps may be adopted:

[0095] (1) providing a base 11a with a first pipe section 121a of a ventilation pipe 12a, an electrode column 15a, an insulating sealing ring 16a, and a second electrode claw 18a, installing the electrode column 15a into the second installation tube 113a of the base 11a through the insulating sealing ring 16a, and then inserting the second electrode claw 18a into the top of the electrode column 15a to form a base assembly; at this time, the conductive portion 183a of the second electrode claw 18a extends upward;

[0096] (2) Providing an atomizer core 141a, a first sealing ring 142a, and a second sealing ring 143a, and respectively sleeve the first sealing ring 142a and the second sealing ring 143a on the upper and lower ends of the atomizer core 141a to form an atomizer assembly 14a;

[0097] (3) Insert the atomizer assembly 14a from top to bottom into the first pipe section 121a of the ventilation pipe 12a, so that the conductive portion 183 of the second electrode claw 18 is in contact with the second electrode 1414 of the atomizer core 141 and is electrically connected to achieve electrical connection between the second electrode 1414 of the atomizer core 141 and the electrode column 15a;

[0098] (4) providing a second pipe segment 123a and a first electrode claw 17a of the ventilation duct 12a, and embedding the first electrode claw 17a into the second pipe 123a of the ventilation duct 12a, with the conductive portion 173a of the first electrode claw 17a extending downward, to form a second pipe segment assembly;

[0099] (5) The second pipe segment assembly is embedded in the top of the first pipe segment 121 a , and the first electrode 1413 a of the atomizer core 141 a is in conductive contact with the conductive portion 173 a of the first electrode claw 17 a , thereby achieving electrical connection between the first electrode 1413 of the atomizer core 141 and the ventilation duct 12 .

[0100] In the above-mentioned assembly steps of the atomizing body 10a, the first electrode claw 17a and the second electrode claw 18a realize electrical contact and conduction between the components. Compared with the related art which realizes electrical contact and conduction by wire welding, the operation is more convenient and quick, and the automatic assembly of the product can be easily realized.

[0101] Figure 12 to Figure 14 The atomizing body 10b in some embodiments of the present invention is shown, and the atomizing body 10b can be used as a substitute for the atomizing body 10 and has the same appearance as the atomizing body 10. As shown in the figure, the atomizing body 10b in some embodiments may include a base 11b, a ventilation pipe 12b, a housing 13b, an atomizing assembly 14b, an electrode column 15b, an insulating sealing ring 16b, a first electrode claw 17b, and a second electrode claw 18b that are coaxially assembled together.

[0102] In some embodiments, the base 11b may be cylindrical and conductive. In some embodiments, the ventilation duct 12b may also be conductive, and is longitudinally embedded in the upper part of the base 11b and electrically connected to the base 11b; the ventilation duct 12b defines a columnar atomization chamber 120b. In some embodiments, the housing 13b may be cylindrical, and is longitudinally sleeved on the upper part of the base 11b and surrounds the ventilation duct 12b; an annular liquid storage chamber 130b is defined between the inner wall surface of the housing 13b and the outer wall surface of the ventilation duct 12b. A liquid inlet hole 122b that connects the liquid storage chamber 130b with the atomization chamber 120b may also be formed on the ventilation duct 12b. In some embodiments, the atomization assembly 14b may be cylindrical and longitudinally arranged in the atomization chamber 120b; a longitudinally penetrating central through hole 1410b may be formed in the middle of the atomization assembly 14b. The electrode column 15b is longitudinally penetrated in the lower part of the base 11b and is electrically insulated from the base 11b; specifically, an insulating sealing ring 16b is longitudinally provided in the lower part of the base 11b, and the electrode column 15b is further penetrated in the insulating sealing ring 16b, thereby realizing an insulating and sealed connection with the base 11b. One end of the first electrode claw 17b is fixed to the upper end of the atomizer assembly 14b and is electrically connected to the upper end of the atomizer assembly 14b, and the other end is elastically contacted with the inner wall of the ventilation duct 12b, thereby electrically connecting the upper end of the atomizer assembly 14b to the ventilation duct 12b. One end of the second electrode claw 18b is fixed to the lower end of the atomizer assembly 14b and is electrically connected to the lower end of the atomizer assembly 14b, and the other end is elastically contacted with the electrode column 15b, thereby electrically connecting the lower end of the atomizer assembly 14b to the electrode column 15b.

[0103] In some embodiments, the electrode column 15b is used to be electrically connected to the positive electrode of the battery device 2b, and the base 11b is used to be electrically connected to the negative electrode of the battery device 2, thereby forming an electrical circuit. After the current is allowed to come out through the positive electrode of the battery device 2b, it passes through the electrode column 15b and the second electrode claw 18b in sequence, reaches the lower end of the atomizer assembly 14b, penetrates the atomizer assembly 14b and heats the atomizer assembly 14b, reaches the upper end of the atomizer assembly 14b, and then passes through the first electrode claw 17b, the ventilation pipe 12b and the base 11b in sequence before flowing back to the negative electrode of the battery device 2. It can be understood that in some embodiments, the electrode column 15b and the base 11b can also be electrically connected to the negative electrode and the positive electrode of the battery device 2b respectively. At this time, the direction of the current is opposite to the above direction.

[0104] For example Fig.13 and Fig.14As shown, in some embodiments, the base 11b can be integrally formed of metal materials, which may include a circular base 111b, a first mounting cylinder 112b longitudinally arranged on the upper surface of the base 111b, and a second mounting cylinder 113b longitudinally arranged on the bottom surface of the base 111b. A through hole 1110b is longitudinally provided in the middle of the base 111b, and the through hole 1110b connects the first mounting cylinder 112b and the second mounting cylinder 113b. The outer wall surface of the second mounting cylinder 113b is formed with a thread structure 1131b for threading the upper end of the battery device 2, and the inner wall surface is formed with a mounting ring 1132b that matches the insulating sealing ring 16b. In some embodiments, the base 11b can have the same structure as the above-mentioned base 11, and the two can be used interchangeably.

[0105] In some embodiments, the ventilation duct 12b can be integrally formed of metal materials, which may include a first pipe section 121b, a second pipe section 123b axially connected to the upper end of the first pipe section 121b, and a third pipe section 125b axially connected to the lower end of the first pipe section 121b, and the inner diameter and outer diameter of the third pipe section 125b, the first pipe section 121b, and the second pipe section 123b are sequentially reduced. The first pipe section 121b defines the above-mentioned atomization chamber 120b, and the above-mentioned liquid inlet hole 122b can be multiple and uniformly formed on the circumference of the side wall of the first pipe section 121b. The outer diameter of the third pipe section 125b is adapted to the inner diameter of the first installation tube 112b, so that the third pipe section 125b is embedded in the first installation tube 112b in the longitudinal direction and is tightly matched with the first installation tube 112b. The height of the third pipe section 125b is equivalent to the height of the first installation tube 112b. In some embodiments, in order to facilitate the embedding of the third pipe segment 125b into the first installation tube 112b, the outer wall surface of the third pipe segment 125b near the lower end is also inwardly formed with a guide portion 1251b, and the outer diameter of the guide portion 125b is smaller than that of the first installation tube 112b. In some embodiments, the inner wall surface at the junction of the first pipe segment 121b and the second pipe segment 123b may be provided with a trumpet-shaped guide surface 1210b inclined toward the outside, which is used to cooperate with the conductive portion 173b of the first electrode claw 17b, so as to facilitate the smooth connection of the conductive portion 173b with the ventilation pipe 12b and facilitate quick assembly.

[0106] In some embodiments, the housing 13b may be made of a transparent material, and its inner diameter is adapted to the outer diameter of the first mounting tube 112b, so that the housing 13b can be sleeved on the first mounting tube 112b at the lower end along the axial direction and tightly fit with the first mounting tube 112b. The upper end surface of the housing 13b may be slightly lower than the upper end surface of the second pipe segment 123b, so as to better match the suction nozzle assembly 20. The inner wall surface of the housing 13b and the inner wall surfaces of the first pipe segment 121b and the second pipe segment 123b define the above-mentioned liquid storage chamber 130b, and an annular liquid injection port 132b is formed between the upper end of the housing 13b and the upper end of the second pipe segment 123b.

[0107] In some embodiments, the atomizer assembly 14b may include a longitudinally arranged cylindrical atomizer core 141b, a first sealing ring 142b sleeved on the upper end of the atomizer core 141b, and a second sealing ring 143b sleeved on the lower end of the atomizer core 141b.

In some embodiments, the heating element 1412b may be formed on the inner wall of the porous body 1411b by screen printing, printing or spraying the heating film slurry on the inner surface of the porous body 1411b, and then sintering to form a heating circuit, which may be distributed on the inner wall of the porous body 1411b in a spiral along the longitudinal direction of the porous body 1411b in some embodiments.

The third electrode portion P is formed at the lower end of the inner wall surface of the porous body 1411b and is connected to the lower end of the heating element 1412b. The fourth electrode portion Q is formed on the lower end surface of the heating element 1412b and is connected to the second electrode claw 18b. In some embodiments, the first electrode 1413b may not be provided with the first electrode portion M, and the second electrode 1414b may not be provided with the third electrode portion P, that is, the first electrode 1413b and the second electrode 1414b are only provided on the end surface of the porous body 1411b, so that the structure of the electrode becomes very simple, the molding process of printing and coating is simpler, and greater convenience is provided for the diversification of electrical connections, for example Fig.21 The atomizing body 1d shown uses conductive silicone to achieve electrical connection.

[0110] For example Fig.13 and Fig.14 As shown, in some embodiments, the electrode column 15b includes a central hole 150b extending upward from the lower end surface, an air outlet 152b formed on the middle side wall, and a card slot 154b formed on the side wall surface, and the air outlet 152b is connected to the central hole 150b for air intake. The card slot 154b is used to engage with the insulating sealing ring 16b. The outer wall surface of the insulating sealing ring 16b forms a card slot 160b for engaging with the mounting ring 1132b of the base 11b. The upper end of the electrode column 15b preferably passes through the through hole 1110b of the base 11b and extends to the vicinity of the lower end of the atomizer core 141b to contact and conduct with the second electrode claw 18b provided at the lower end of the atomizer core 141b.

[0111] In some embodiments, the first electrode claw 17b may be made of materials such as phosphor copper or 316 stainless steel, and a gold-plated layer may be provided on its surface.

Each extension portion 172b and the corresponding conductive portion 173b form an elastic conductive arm of the first electrode claw 17b. It can be understood that the number of elastic conductive arms of the first electrode claw 17b is not limited to three, one or more than one is fine, and having multiple elastic conductive arms can make the electrical connection more reliable and the assembly more convenient.

[0112] In some embodiments, the mounting portion 171b may be in the shape of a circular ring sheet and electrically contact the second electrode portion N of the first electrode 1413b. In some embodiments, the extension portion 172b may be in the shape of a strip and have good elasticity. Preferably, there are two or more extension portions 172b to ensure a more reliable electrical connection. When there are multiple extension portions 171b, they are preferably evenly distributed on the inner circle of the mounting portion 171b and extend upward. A conductive portion 173b is provided at the end of each extension portion 172b for elastically contacting the ventilation duct 12b. In some embodiments, the conductive portion 173b may be in the shape of a spoon, the inclined surface of the spoon is inclined inwardly, and has a guiding function, and the bottom of the spoon is in the shape of a circular arc transition, so that it can better contact and conduct with the ventilation duct 12b. In some embodiments, the mounting portion 171b further includes a plurality of first protrusions 174b protruding toward the upper end surface of the atomizer core 141b. This is mainly because the annular sheet-shaped mounting portion 171b is prone to burrs during the manufacturing process, which easily makes the contact between the mounting portion 171b and the upper end surface of the atomizer core 141b unstable. Adding the first protrusions 174b can better contact the first electrode 1413b on the upper end surface of the atomizer core 141b and provide better consistency. The number of the first protrusions 174b is preferably two to three, and they are evenly distributed around the circumference of the mounting portion 171b.

[0113] In some embodiments, the second electrode claw 18b may be made of materials such as phosphor copper or 316 stainless steel, and a gold-plated layer may be provided on its surface. The second electrode claw 18b is preferably made of phosphor copper material, and the impedance of phosphor copper material is relatively small.

Each extension portion 182b and the corresponding conductive portion 183b form an elastic conductive arm of the second electrode claw 18b. It can be understood that the number of elastic conductive arms of the second electrode claw 18b is not limited to three, one or more than one is fine, and having multiple elastic conductive arms can make the electrical connection more reliable and the assembly more convenient.

[0114] In some embodiments, the mounting portion 181b may be in the shape of a circular ring sheet and electrically contact the fourth electrode portion Q of the second electrode 1414b. In some embodiments, the extension portion 182b may be in the shape of a strip and have good elasticity. Preferably, there are two or more extension portions 182b to ensure a more reliable electrical connection. When there are multiple extension portions 181b, they are preferably evenly distributed in the inner circle of the mounting portion 181b and extend downward. A conductive portion 183b is provided at the end of each extension portion 182b for elastically contacting the upper end of the electrode column 15b. In some embodiments, the conductive portion 183b may be in the shape of a spoon, the inclined surface of the spoon is inclined outward, and has a guiding function. The bottom of the spoon has an arc transition, and can better contact and conduct with the side wall surface of the upper end of the electrode column 15b. In some embodiments, the mounting portion 181b further includes a plurality of second protrusions 184b protruding toward the lower end surface of the atomizer core 141b. This is mainly because the annular sheet-shaped mounting portion 181b is prone to burrs during the manufacturing process, which easily makes the contact between the mounting portion 181b and the lower end surface of the atomizer core 141b unstable. Adding the second protrusions 184b can better contact the second electrode 1414b on the lower end surface of the atomizer core 141b and have better consistency. The number of the second protrusions 184b is preferably two to three, and they are evenly distributed on the circumference of the mounting portion 181b.

[0129] Read also Fig. 20 In some embodiments, the atomizing core 141c may include a cylindrical porous body 1411c, a first heating element 1412c and a second heating element 1415c disposed on the inner wall of the porous body 1411c, an electrical connection portion 1416c disposed on the upper end surface of the porous body 1411c and electrically connected to the upper ends of the first heating element 1412c and the second heating element 1415c, a first electrode 1413c disposed on the lower end surface of the porous body 1141 and electrically connected to the lower end of the first heating element 1412c, and a second electrode 1414c disposed on the lower end surface of the porous body 1141 and electrically connected to the lower end of the second heating element 1415c. It can be understood that the porous body 1411c is not limited to a cylindrical shape, and other cylindrical shapes such as a square cylinder and an elliptical cylinder are also applicable.

[0130] The porous body 1411c can be made of porous ceramic in some embodiments. The first heating element 1412c and the second heating element 1415c can be heating circuits in some embodiments, which are formed on the inner wall surface of the porous body 1411c by printing and spraying the heating film slurry (silver paste or copper paste, etc.) on the inner surface of the porous body 1411c, and then sintering. The first electrode 1413c, the second electrode 1414c and the electrical connection part 1416c can be formed by printing or spraying the conductive film slurry such as silver paste on the porous body blank and sintering in some embodiments. It can be understood that the first heating element 1412c, the second heating element 1415c, the first electrode 1413c, the second electrode 1414c and the electrical connection part 1416c can also be processed by heating metal sheets in some embodiments. The first electrode 1413c and the second electrode 1414c can be fan-shaped in some embodiments, and there is a gap between them. The lower end surface of the porous body 1411c is provided with a groove 1417c corresponding to the interval between the first electrode 1413c and the second electrode 1414c, and the electrical connection portion 1416c may be annular in some embodiments. In some embodiments, the lower end of the porous body 1411c has a larger diameter, which can better contact the first electrode column 15c and the second electrode column 16c, and also to better open the groove 1417c, so as to separate the first electrode 1413c and the second electrode 1414c. In some embodiments, the first electrode column 15c and the second electrode column 16c may be elastic ejector pins.

[0131] In some embodiments, the first heating element 1412c may include a plurality of first heating strips distributed in parallel and spaced in the longitudinal direction of the inner wall surface of the porous body 1411c, and these first heating strips constitute a first heating circuit arranged in parallel and spaced, and the upper end is connected to the electrical connection part 1416c, and the lower end is connected to the first electrode 1413c; the width of each heating strip is 0.1mm-0.6mm, and the thickness is 0.02-0.2mm. In some embodiments, the second heating element 1415c may include a plurality of second heating strips distributed in parallel and spaced in the longitudinal direction of the inner wall surface of the porous body 1411c, and these second heating strips constitute a second heating circuit arranged in parallel and spaced, and the upper end is connected to the electrical connection part 1416c, and the lower end is connected to the second electrode 1414c.

[0132] In some embodiments, the resistivity of the first heating element 1412c and the second heating element 1415c is greater than the resistivity of the first electrode 1413c, the second electrode 1414c and the electrical connection portion 1416c. Preferably, the resistivity of the former is more than 20 times that of the latter. In some embodiments, the first heating element 1412c and the second heating element 1415c can be made of nickel-chromium alloy, iron-chromium-aluminum alloy, silver-palladium alloy and other materials, which can be formed by sintering after the heating element slurry is formed on the inner surface of the porous body blank by silk screen printing or printing. It can be understood that the circuits of the first heating element 1412c and the second heating element 1415c are not limited to those shown in the figure, and can also be other suitable patterns.

[0133] In some embodiments, the second sealing ring 143c may include a first through hole 1431c, a second through hole 1432c and two convex ribs 1433c. Preferably, the line connecting the first through hole 1431c and the second through hole 1432c intersects perpendicularly with the line connecting the two convex ribs 1433c, so that when the second sealing ring 143c is matched with the lower end of the porous body 1411c, the first through hole 1431c and the second through hole 1432c are respectively opposite to the first electrode 1413c and the second electrode 1414c. The first through hole 1431c and the second through hole 1432c are used for the upper ends of the first electrode column 15c and the second electrode column 16c to pass through, respectively, so that the upper ends of the first electrode column 15c and the second electrode column 16c are respectively in electrical contact and conduction with the first electrode 1413c and the second electrode 1414c. Here, when the first electrode column 15c and the second electrode column 16c are respectively connected to the positive electrode and the negative electrode of the battery device, the current flowing out from the positive electrode of the battery device will flow back to the negative electrode of the battery device from the first electrode column 15c, the first electrode 1413c, the first heating element 1412c, the electrical connection portion 1416c, the second heating element 1415c, the second electrode 1414c and the second electrode column 16c in sequence, thereby realizing the heating process of the first heating element 1412c and the second heating element 1415c. Compared with the related art that requires auxiliary conduction through components such as the base and the ventilation duct, the electrical circuit of this heating process has more flexible selection of materials for the base and the ventilation duct, which can be made of non-metallic materials. Therefore, the cost of the entire atomizer 1c can be significantly reduced. In addition, the automated production of the atomizer 1c is more convenient.

[0134] Fig.21 The atomizing body 10d in some embodiments of the present invention is shown. The atomizing body 10d can be a substitute for the atomizing body 10b described above, and may include a base 11d, a ventilation pipe 12d, a shell 13d, an atomizing assembly 14d, an electrode column 15d, and an insulating seal ring 16d that are coaxially assembled together. The structures of the base 11d, the ventilation pipe 12d, the shell 13d, the electrode column 15d, and the insulating seal ring 16d can be respectively the same as the base 11b, the ventilation pipe 12b, the shell 13b, the electrode column 15b, and the insulating seal ring 16b of the atomizing body 10b, and will not be repeated here. The main differences in the structures of the two are: (1) The atomizing body 10d omits the first electrode claw 17b and the second electrode claw 18b compared to the atomizing body 10b; (2) The atomizing assembly 14d is different from the atomizing assembly 14b.

[0135] The atomizer assembly 14d may include a cylindrical atomizer core 141d disposed longitudinally, a first sealing ring 142d sleeved on the upper end of the atomizer core 141d, and a second sealing ring 143d sleeved on the lower end of the atomizer core 141d. The structure of the atomizer core 141d is the same as that of the atomizer core 141d of the atomizer assembly 14b, and may include a cylindrical porous body 1411d, a heating element 1412d disposed on the inner wall surface of the porous body 1411d, a first electrode 1413d disposed on the upper end surface of the porous body 1411d and electrically connected to the upper end of the heating element 1412d, and a second electrode 1414d disposed on the lower end surface of the porous body 1411d and electrically connected to the lower end of the heating element 1412d. The main differences between the two structures are: (1) the first sealing ring 142d is conductive, that is, it has both sealing and conductive functions, and can be made of conductive silicone; (2) the second sealing ring 143d is a composite sealing ring, the inner ring portion of which is conductive to be electrically connected to the electrode column 15d; the outer ring portion is non-conductive to electrically insulate the conductive inner ring portion from the conductive base 11d.

[0136] Based on the above structural differences, in the atomizing body 10d, the first electrode 1413d is electrically connected to the ventilation duct 12d through the first sealing ring 142d, and the second electrode 1414d is electrically connected to the electrode column 15d through the conductive inner ring portion of the second sealing ring 143d. Compared with the atomizing body 10b, since there is no electrode claw extending into the air flow channel, the interference to the air flow in the air flow channel is reduced, and the air flow is smoother. In addition, after omitting the first electrode claw 17b and the second electrode claw 18b, the manufacturing cost can be reduced, the assembly steps are reduced, and the stability of the product is improved.

[0137] It should be pointed out that, for those skilled in the art, without departing from the concept of the present invention, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, all of which belong to the protection scope of the present invention; therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
