Detailed Description

In order to more clearly describe the present invention, the present invention will be further described with reference to the accompanying drawings.

It should be understood that the terms "front", "back", "left", "right", "up", "down", "first", "second", etc. are used for convenience of describing the technical solutions of the present invention, and do not indicate that the devices or elements referred to must have special differences, and thus, the present invention cannot be construed as being limited. It will be understood that when an element is referred to as being "coupled" to another element, it can be directly coupled to the other element or intervening elements may also be present. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Fig. 1 and 2 illustrate an electronic aerosol device according to some embodiments of the present invention, which may be used for a user to inhale an aerosol, and may include an atomizer 1 and a battery device 2 coupled to the atomizer 1. The nebulizer 1 may be used for storing and heat nebulizing a liquid aerosol-generating substrate, such as a liquid medicament, and for conducting the aerosol out. The battery means 2 may be used to power the atomiser 1. In some embodiments, the atomizer 1 and the battery device 2 may each have a cylindrical shape, and both are mechanically and electrically connected together in the axial direction. In some embodiments, the nebulizer 1 and the battery device 2 are detachably connected together by means of a threaded connection. It will be appreciated that the atomiser 1 and the battery means 2 are not limited to being threadably connected, but may be removably connected together by magnetic attraction. It will be understood that the atomizer 1 and the battery device 2 are not limited to the cylindrical shape, but may be cylindrical shapes having an oval, racetrack, or irregular shape in cross section.

As shown in fig. 3 to 5, the atomizer 1 may in some embodiments comprise a lower cylindrical atomizing body 10 for storing and heating an atomized liquid aerosol-generating substrate, and a nozzle assembly 20 axially connected to an upper end of the atomizing body 10 for plugging and guiding the liquid aerosol-generating substrate in the atomizing body 10. In some embodiments, the nozzle assembly 20 is inserted into the upper end of the atomising body 10 with a tight fit to facilitate the injection of the liquid aerosol-generating substrate into the atomising body 10. The nozzle assembly 20 may be removably connected to the upper end of the atomising body 10, in which case the liquid aerosol-generating substrate may be added repeatedly, increasing the lifetime of the atomiser 1. For some single-use atomizers 1, the nozzle assembly 20 and the atomizing body 10 may also be non-detachable, i.e., they are locked once connected and cannot be separated without destroying the existing structure. Even if the atomizer is reusable, the atomizer may be of an integrated structure by adding a liquid injector, as in the atomizer 1c shown in fig. 16.

Referring to fig. 6 and 7 together, the atomizing body 10 may include a base 11, a vent pipe 12, a housing 13, an atomizing assembly 14, an electrode post 15, an insulating sealing ring 16, a first electrode jaw 17, and a second electrode jaw 18, which are coaxially assembled together in some embodiments.

The base 11 may be cylindrical in some embodiments and may be electrically conductive. The ventilation duct 12, which may also be electrically conductive in some embodiments, is embedded in the upper portion of the base 11 along the longitudinal direction and is electrically connected to the base 11; the vent tube 12 defines a cylindrical aerosolizing chamber 120. The housing 13, which may be cylindrical in some embodiments, is sleeved on the upper portion of the base 11 along the longitudinal direction and surrounds the ventilation duct 12; an annular reservoir 130 is defined between the inner wall surface of the housing 13 and the outer wall surface of the vent conduit 12. The vent conduit 12 may also be formed with a fluid inlet aperture 122 that communicates the reservoir chamber 130 with the aerosolization chamber 120. The atomizing assembly 14 may be cylindrical in some embodiments and disposed longitudinally in the atomizing chamber 120; the atomizing assembly 14 may define a longitudinally extending air flow passage 140 at a central portion thereof. The electrode column 15 is longitudinally arranged at the lower part of the base 11 in a penetrating way and is electrically insulated from the base 11; specifically, an insulating sealing ring 16 is longitudinally arranged at the lower part of the base 11, and the electrode column 15 is further arranged in the insulating sealing ring 16 in a penetrating manner, so that the insulating sealing connection with the base 11 is realized. One end of the first electrode claw 17 is fixed on the inner wall of the air duct 12 and electrically connected with the air duct 12, and the other end is elastically contacted with the upper end of the atomization assembly 14, so as to electrically connect the upper end of the atomization assembly 14 with the air duct 12. One end of the second electrode claw 18 is fixed on the electrode column 15 and electrically connected to the electrode column 15, and the other end is in elastic contact with the lower end of the atomizing assembly 14 to electrically connect the lower end of the atomizing assembly 14 to the electrode column 15.

In some embodiments, the electrode post 15 is used to electrically connect with the positive electrode of the battery device 2, and the base 11 is used to electrically connect with the negative electrode of the battery device 2, thereby forming an electrical circuit. After the current can come out through the positive electrode of the battery device 2, the current sequentially passes through the electrode column 15 and the second electrode claw 18, reaches the lower end of the atomization assembly 14, penetrates through the atomization assembly 14, and after the atomization assembly 14 generates heat, reaches the upper end of the atomization assembly 14, and then sequentially flows back to the negative electrode of the battery device 2 after passing through the first electrode claw 17, the vent pipe 12 and the base 11. It is understood that in some embodiments, the electrode shaft 15 and the base 11 may also be electrically connected to the negative electrode and the positive electrode of the battery device 2, respectively, and the current flow direction is opposite to the above direction.

As shown in fig. 6 and 7, the base 11 may be integrally formed by a metal material in some embodiments, and may include a circular base 111, a first mounting tube 112 longitudinally disposed on the upper surface of the base 111, and a second mounting tube 113 longitudinally disposed on the bottom surface of the base 111, wherein a through hole 1110 longitudinally penetrating is disposed in the middle of the base 111, and the through hole 1110 communicates the first mounting tube 112 and the second mounting tube 113. The outer wall surface of the second mounting tube 113 is formed with a screw structure 1131 for screwing the upper end of the battery device 2, and the inner wall surface is formed with a mounting ring 1132 fitted to the insulating seal ring 16.

The vent line 12 may be integrally formed of a metal material in some embodiments, and may include a first pipe segment 121, a second pipe segment 123 axially connected to an upper end of the first pipe segment 121, and a third pipe segment 125 axially connected to a lower end of the first pipe segment 121, wherein inner and outer diameters of the third pipe segment 125, the first pipe segment 121, and the second pipe segment 123 decrease sequentially. The first pipe segment 121 defines the atomizing chamber 120, and the liquid inlet holes 122 may be a plurality of holes uniformly formed on the circumferential surface of the first pipe segment 121. A stop ring 1231 extending toward the central axis may be disposed on the inner wall surface of the second tube segment 123 near the first tube segment 123, for providing an axial stopping force to the first electrode claw 17. The end surface of the retainer ring 1231 close to the first electrode claw 17 may be a plane perpendicular to the central axis of the second tube segment 123, and the end surface far from the first electrode claw 17 may be a conical surface with a trumpet shape. The outer diameter of third pipe segment 125 is matched to the inner diameter of first mounting cylinder 112, so that third pipe segment 125 is longitudinally embedded in first mounting cylinder 112 and tightly fitted with first mounting cylinder 112. The height of the third pipe section 125 corresponds to the height of the first mounting cylinder 112. In some embodiments, to facilitate the insertion of the third pipe segment 125 into the first mounting cylinder 112, a guide 1251 is further formed on the outer wall surface of the third pipe segment 125 near the lower end, and the outer diameter of the guide 125 is smaller than that of the first mounting cylinder 112.

The housing 13 may be made of a transparent material in some embodiments, and has an inner diameter matched with the outer diameter of the first mounting cylinder 112, so that the housing 13 can be sleeved on the first mounting cylinder 112 at the lower end in the axial direction and tightly fit with the first mounting cylinder 112. The upper surface of the housing 13 may be slightly lower than the upper surface of the second tube segment 123 to better mate with the nozzle assembly 20. The inner wall surface of the housing 13 and the inner wall surfaces of the first tube segment 121 and the second tube segment 123 define the liquid storage chamber 130 therebetween, and an annular liquid injection port 132 is formed between the upper end of the housing 13 and the upper end of the second tube segment 123.

The atomizing assembly 14 may include a cylindrical atomizing core 141 disposed longitudinally, a first sealing ring 142 sleeved on an upper end of the atomizing core 141, and a second sealing ring 143 sleeved on a lower end of the atomizing core 141.

The first sealing ring 142 may have an L-shaped cross-section for sealing a gap between the upper end of the atomizing core 141 and the upper end of the first pipe segment 121. In some embodiments, the first sealing ring 142 may include a cylindrical first sealing part 1421 and a circular second sealing part 1423 connected to an upper end edge of the first sealing part 1421, the first sealing part 1421 is sleeved on an outer wall surface of an upper end of the atomizing core 141, and the second sealing part 1423 covers an upper end surface of the atomizing core 141. The inner diameter of the second sealing part 1423 is preferably larger than the bore diameter of the atomizing core 141 so that the first electrode claw 17 is not blocked by the second sealing part 1423 when it is engaged with the atomizing core 141.

The second sealing ring 143 may also have an L-shaped cross-section for sealing a gap between the lower end of the atomizing core 141 and the third pipe segment 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 a lower end edge of the third sealing portion 1431, the third sealing portion 1431 is sleeved on an outer wall surface of the lower end of the atomizing core 141, and the fourth sealing portion 1433 covers a lower end surface of the atomizing core 141. The middle part of the outer wall surface of the atomizing core 141 can be opposite to the liquid inlet hole 122. The atomizing core 141 has a central through hole 1410 formed in the middle thereof and extending longitudinally therethrough. The fourth sealing part 1433 is preferably larger in inner diameter than the aperture of the atomizing core 141 so that the second electrode claw 18 is not blocked by the fourth sealing part 1433 when being engaged with the atomizing core 141.

In some embodiments, the inner wall surface of the first seal 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 and

second sealing parts

1421 and 1423. The first ventilation channel 1420 may be designed to have a small enough size to have a capillary force in a use state, so as to conduct the air flow channel between the liquid storage cavity 130 and the ventilation pipe 12 when the liquid storage cavity 130 is under a large negative pressure, so as to achieve a gas-liquid balance and prevent dry burning. In some embodiments, the second seal ring 143 may have a second ventilation groove 1430 formed in a labyrinth shape on an inner wall surface thereof, and the second ventilation groove 1430 may penetrate the inner wall surfaces of the third seal part 1431 and the fourth seal part 1433 to have 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 can be used in common, so as to facilitate automatic installation and save the mold opening cost of the sealing rings.

It should be understood that the first sealing ring 142 and the second sealing ring 143 may alternatively be provided with a ventilation structure, and both have advantages and disadvantages. When only the first sealing ring 142 has the ventilation structure, if liquid leaks from the first ventilation channel 1420 of the first sealing ring 142, some of the leaked liquid flows downward from the upper end of the atomizing core 141, and is absorbed by the atomizing core 141 and atomized again. When only the second gasket 143 has the ventilation structure, although possible leakage easily flows into the base 11, since the direction of the air flow in the air flow channel is from bottom to top, the air is supplied more smoothly through the second gasket 143. In some embodiments, the silicone sealant 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 contacting the atomizing core 141 to the surface contacting the vent pipe 12 can better seal the lower end of the atomizing core 141 by interference fit, so as to avoid liquid leakage. When comparing the two, the thickness of the corresponding portion of the first seal ring 142 is compared.

Referring to fig. 8, the atomizing core 141 may include a cylindrical porous body 1411, a heating element 1412 disposed on an inner wall surface of the porous body 1411, a first electrode 1413 disposed on an upper end of the inner wall surface of the porous body 1411 and electrically connected to an upper end of the heating element 1412, and a second electrode 1414 disposed on a lower end of the inner wall surface of the porous body 1411 and electrically connected to a lower end of the heating element 1412. The porous body 1411 may be a porous ceramic in some embodiments, and may be a small size porous body 1411, such small size porous body 1411 may have a length of 0.8-1.2cm in some embodiments, and an inner diameter of 0.18-0.22 cm.

The heating element 1412, which may be made of a material such as a nickel-chromium alloy, an iron-chromium-aluminum alloy, a silver-palladium alloy, etc. in some embodiments, is printed and sprayed on the inner surface of the blank of the porous body 1411, and is formed on the inner wall surface of the porous body 1411 by sintering, and may include two flat and long rectangular heating lines B arranged in parallel in the axial direction of the porous body 1411 and a connecting line C connecting the two heating lines in series, wherein the two heating lines B extend along the inner wall surface of the porous body 1411 in the circumferential direction so as to be C-shaped as a whole. The heating body 1412 may further include an upper end wire D and a lower end wire a connected to the upper and lower ends, respectively, to be electrically connected to the first and

second electrodes

1413 and 1414, respectively.

The first electrode 1413 and/or the second electrode 1414 may be made of silver, copper, or other materials, and may be formed on an inner wall surface of the cylindrical porous body 1411 by coating/printing with silver paste or copper paste and sintering, and at least a part of the first electrode is connected to the heating element 1412. The first electrode 1413 and/or the second electrode 1414 may be C-shaped in some embodiments, which is typically first printed with a paste for the heating element 1412 onto a green body of the porous body 1411, followed by printing or coating with an electrode paste, and then sintered together. In some embodiments, the width of the gap of the first electrode 1413 may be smaller than the width of the conductive portion 173, so as to electrically contact all the conductive portions 173 of the first electrode claw 17; the width of the gap of the second electrode 1414 may be smaller than the width of the conductive portions 183 so as to electrically connect with all the conductive portions 183 of the second electrode tab 18. It is understood that the heating element 1412 may be made of a metal heating sheet in some embodiments, and the porous body 1411 is also limited to a porous ceramic material, and other suitable porous body materials may also be used. It is to be understood that the first electrode 1413 and/or the second electrode 1414 are not limited to the C-shaped distribution at the end of the inner wall surface of the porous body 1411, but may be distributed over the entire circumference of the end of the inner wall surface of the porous body 1411, i.e., in a ring shape.

The first electrode 1413 and/or the second electrode 1414 are/is disposed without perforating and threading the porous body 1411, so that the internal structure of the porous body 1411 is more complete, controllable and reliable, and the consistency of the product is well ensured. In addition, a lead can be avoided, and the manufacturing difficulty and the production cost are reduced. This is more obvious for application to the miniaturized porous body 1411.

In some embodiments, it is also beneficial to dispose the first electrode 1413 and the second electrode 1414 on two ends of the inner wall surface of the small-sized porous body 1411, because the inner wall area of the small-sized porous body 1411 is small, and if two electrodes are disposed on one end, the area of the two electrodes is too small to facilitate stable electrical connection with the electrode connecting member, and short circuit is also easily caused, and by disposing the first electrode 1413 and the second electrode 1414 on two ends, the first electrode 1413 and the second electrode 1414 can be disposed conveniently, and the area of the first electrode 1413 and the second electrode 1414 can be made larger to facilitate stable electrical connection with the electrode connecting member.

As further shown in fig. 6 and 7, the electrode shaft 15 in some embodiments includes a central bore 150 extending upwardly from the lower end, an outlet bore 152 formed in the top sidewall, and a locking slot 154 formed in the sidewall, the outlet bore 152 communicating with the central bore 150 for inlet of air. The locking groove 154 is used to engage with the insulating seal ring 16. The outer wall surface of the insulating seal ring 16 forms a locking groove 160 for engaging with the mounting ring 1132 of the base 11.

The first electrode tab 17 may be made of phosphor copper or 316 stainless steel, and the surface thereof may be plated with gold. The first electrode tab 17 is preferably made of a phosphor-copper material, which has a relatively small resistance. The first electrode tab 17 may include a mounting portion 171 embedded in an inner wall surface of the second tube 123, three extending portions 172 connected to the mounting portion 171, and three conductive portions 173 connected to the three extending portions 172, respectively. Each extension portion 172 and the corresponding conductive portion 173 form an elastic conductive arm of the first electrode tab 17. It is understood that the number of the elastic conductive arms of the first electrode claw 17 is not limited to three, one or more elastic conductive arms may be provided, and the electric connection may be more reliable and the assembly may be more convenient due to the plurality of elastic conductive arms.

The mounting portion 171 may be cylindrical in some embodiments, and has a longitudinal break 1710 extending through both lateral edges, the break 1710 being configured to deform during installation to ensure that the mounting portion 171 is better secured to the inner wall of the second tube segment 123. Specifically, a trumpet-shaped guide surface 1210 is arranged at the joint of the second pipe section 123 and the first pipe section 121, and when the first electrode claw 17 is plugged into the second pipe section 123 along the axial direction, the guide surface 1210 applies a component force inward in the radial direction to the mounting part 171 of the first electrode claw 17, so that the fracture 1710 of the mounting part 171 is closed, the outer diameter is reduced, and the mounting part can be plugged into the second pipe section 123; when mounted in place, mounting portion 171 provides a reactive force against the inner wall of second tube section 123, thereby securely fastening second tube section 123. It will be appreciated that the mounting portion 171 may also be integrally formed with the second tubular segment 123 in some embodiments. In some embodiments, the mounting portion 171 may be axially inserted into the upper end of the central through hole 1410 of the atomizing core 141 and elastically abutted against the first electrode 1413, so that the elastic conductive arm may be extended to elastically contact the air vent pipe 12.

The extending portion 172 may be a bar shape in some embodiments and has good elasticity, and after it is bent and extended from the mounting portion 171 toward the central axis of the mounting portion 171 for a certain distance, it is extended along the central axis parallel to the mounting portion 171 toward a direction away from the mounting portion 171, so as to provide a space for the conductive portion 173 to be bent toward the central axis away from the mounting portion 171 and provide good elasticity characteristics. The extension 172 preferably has two or more to ensure more reliable electrical connection; when the number of the extending portions 171 is plural, it is preferable that the extending portions are uniformly distributed on the lower edge of the mounting portion 171 and extend downward. Specifically, the extension portion 172 extends from the mounting portion 171 toward the central axis of the mounting portion 171 at an angle and then extends in a direction away from the mounting portion 171 along the central axis. The end of each extending portion 172 is provided with a conductive portion 173 for elastically contacting the first electrode 1413 of the atomizing core 141. The conductive portion 173 may be in the shape of a scoop in some embodiments, and specifically, the conductive portion 173 extends obliquely away from the central axis of the mounting portion 171, and then bends to extend obliquely toward the central axis. The slope of the spoon-like structure slopes inward to provide a guiding function, and the bottom of the spoon-like structure is in arc transition to better contact with the first electrode 1413 of the atomizing core 141, and will not scratch the first electrode 1413 during assembly. The vertical distance from the bottom of the conductive portion 173 to the central axis is slightly greater than the radius of the central through hole 1410 of the atomizing core 141 at the position of the first electrode 1413, so that when the conductive portion 173 is axially inserted into the central through hole 1410, because the conductive portion 173 has an inclined surface inclined toward the inner side, the atomizing core 141 exerts a force on the conductive portion 173, and has a component force toward the central axis, so that the extending portion 171 is elastically deformed toward the central axis, and the conductive portion 173 can be inserted. After the conductive portion 173 is inserted into the central through hole 1410, the elastic force of the extension portion 171 causes the conductive portion 173 to be tightly contacted with the first electrode 1413.

The second electrode tab 18 may be made of phosphor copper or 316 stainless steel in some embodiments, and the surface thereof may be plated with gold. The second electrode tab 18 is preferably made of a phosphor-copper material, which is relatively low resistance. The second electrode claw 18 may include a mounting portion 181 sleeved on the upper portion of the electrode column 15, an extending portion 182 connected to the mounting portion 181, and a conductive portion 183 connected to the extending portion 182. The mounting portion 181 may in some embodiments be cylindrical and have a longitudinal cut 1810 through both side edges, the cut 1810 allowing deformation during mounting to ensure that the mounting portion 181 is better secured to the upper portion of the electrode shaft 15, it being understood that the mounting portion 181 may in some embodiments also be integral with the electrode shaft 15. The extension part 182 may be a bar shape in some embodiments and has good elasticity, and the extension part 182 preferably has two or more to ensure more reliable electrical connection; when there are a plurality of extending portions 181, it is preferable that the extending portions are uniformly distributed on the lower edge of the mounting portion 181 and extend downward. The end of each extending portion 182 is provided with a conductive portion 183 for elastically contacting the second electrode 1414 of the atomizing core 141. The conductive portion 183 may be in the form of a scoop, the slope of which is inclined inward to provide a guiding function, and the bottom of the scoop is rounded to better contact the second electrode 1414 of the atomizing core 141 and to prevent the second electrode 1414 from being scratched during assembly. In some embodiments, the second electrode tab 18 may be identical in structure to the first electrode tab 17, and may be common to both, which may reduce assembly difficulty and cost.

When the atomizing body 10 is assembled, the following steps may be employed:

(1) providing a base 11, an electrode column 15, an insulating sealing ring 16 and a second electrode claw 18, installing the electrode column 15 into a second installation cylinder 113 of the base 11 through the insulating sealing ring 16, and sleeving the second electrode claw 18 on the top of the electrode column 15 to form a base assembly; at this time, the conductive portion 183 of the second electrode tab 18 projects upward;

(2) providing a ventilation pipe 12 and a first electrode claw 17 shown in the figure, and embedding the first electrode claw 17 into a second pipe 123 of the ventilation pipe 12, wherein a conductive part 173 of the first electrode claw 17 extends downwards;

(4) the atomization assembly 14 is plugged into the vent pipe 12 from bottom to top, the first electrode 1413 of the atomization core 141 is in conductive contact with the conductive part 173 of the first electrode claw 17, so that the first electrode 1413 of the atomization core 141 is electrically connected with the vent pipe 12, and a vent pipe assembly is formed;

(5) the vent pipe assembly is inserted into the first mounting cylinder 112 at the top of the base assembly, so as to realize the tight fit and electrical connection between the vent pipe 12 and the base 11, and in addition, the conductive part 183 of the second electrode claw 18 is in contact conduction with the second electrode 1414 of the atomizing core 141;

In the above assembling step of the atomizing main body 10, the first electrode claw 17 and the second electrode claw 18 are electrically connected to each other quickly, and compared with the related art in which the components are electrically connected by wire welding, the operation is more convenient and faster, and the automatic assembly of the product is easier to achieve. It is to be understood that the above-mentioned sequence numbers before the steps are merely for convenience of description, and do not indicate the order of the respective steps.

In the assembled nebulizer 1, the liquid aerosol-generating substrate is first injected into the liquid storage chamber 130 of the nebulizer body 10 through the injection port 132, and after the liquid storage chamber 130 is filled with the aerosol-generating substrate, the nozzle assembly 20 is inserted into the injection port 132 to close the liquid storage chamber 130, and the air vent 220 of the nozzle assembly 20 is communicated with the air vent 12. At this time, the liquid aerosol-generating substrate reaches around the atomizing wick 144 via the liquid inlet hole 122, and the porous body 1411 of the atomizing wick 141 sucks the liquid aerosol-generating substrate to the inner surface to contact the heat-generating body 1412 by capillary force. When the atomizing assembly 1 is mounted on the battery device 2 in use, when a user inhales through the nozzle unit 22, the external air enters through the central hole 150 of the electrode post 15, passes through the through hole 1110 of the base 11, enters the central through hole 1410 of the atomizing core 141, and is then discharged through the air guide hole 220 of the nozzle unit 20, as shown by the arrow X in fig. 3. At the same time, an air switch (not shown) in the battery device 2 is turned on, and the battery device 2 is driven to supply power to the atomizer 1. The heating element 1412 of the atomizing core 141 is energized to generate heat, and heats and atomizes the liquid aerosol-generating substrate on the inner surface of the porous body 1411 to form aerosol, and the aerosol is entrained by the air flow after being mixed with the air flowing through the central through hole 1410.

Fig. 21 shows an atomising body 10d according to some embodiments of the invention, which atomising body 10d may be an alternative to the atomising body 10b described above and may comprise a base 11d, a vent tube 12d, a housing 13d, an atomising assembly 14d, an electrode post 15d and an insulating seal 16d assembled together coaxially. The base 11d, the vent pipe 12d, the housing 13d, the electrode column 15d, and the insulating seal ring 16d may have the same structure as the base 11b, the vent pipe 12b, the housing 13b, the electrode column 15b, and the insulating seal ring 16b of the atomizing body 10b, respectively, and thus, the description thereof is omitted. The two are structurally different in that: (1) the atomizing body 10d omits the first electrode claw 17b and the second electrode claw 18b compared to the atomizing body 10 b; (2) atomization assembly 14d is different than atomization assembly 14 b.

The atomizing assembly 14d may include a cylindrical atomizing core 141d disposed longitudinally, a first sealing ring 142d sleeved on the upper end of the atomizing core 141d, and a second sealing ring 143d sleeved on the lower end of the atomizing core 141 d.

Compared with the atomizing main body 10b, since no electrode claw extends into the airflow passage, the interference of the airflow in the flowing process in the airflow passage is reduced, and the airflow is smoother. In addition, after the first electrode claw 17b and the second electrode claw 18b are omitted, the manufacturing cost can be reduced, the assembly steps can be reduced, and the stability of the product can be improved.

It should be noted that, for a person skilled in the art, the above technical features can be freely combined, and several changes and modifications can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the claims of the present invention.
