Fig. 1-2 illustrate an electronic atomizer 1 according to some embodiments of the present invention, where the electronic atomizer 1 includes an atomizer 100 and a power supply device 200 cooperatively connected with the atomizer 100.

In some embodiments, the atomizer 100 and the power supply device 200 may each have a generally cylindrical configuration, and the two may be mechanically and electrically coupled together in the axial direction. Further, the atomizer 100 and the power supply device 200 may be detachably connected by means of a screw connection.

Further, the cross-sectional shape of the atomizer 100 and/or the power supply apparatus 200 is not limited to a circular shape, and may be other shapes such as an oval shape, a racetrack shape, and a rectangular shape.

As shown in fig. 3-5, the atomizer 100 may include a liquid-storing atomizing body 10 and a nozzle body 20 disposed at an upper end of the liquid-storing atomizing body 10. A reservoir chamber 110 for holding a liquid substrate and an output channel 120 isolated from the reservoir chamber 110 for delivering an aerosol are formed in the reservoir atomizing body 10. The nozzle body 20 is closed at the upper end of the reservoir 110, and has a suction passage 210 formed therein to communicate with the output passage 120.

Specifically, the nozzle body 20 may include the nozzle 21, and the suction passage 210 may be formed in the longitudinal direction within the nozzle 21 and may be disposed coaxially with the nozzle 21. In some embodiments, the suction nozzle 21 may be made of a hard material such as plastic, which is beneficial to the structural stability of the suction channel 210. Further, the suction nozzle 21 may include a blocking portion 211 at a lower portion and a suction nozzle portion 212 at an upper portion. The mouthpiece portion 212 may have a flat shape, which may better fit the lips, and may enable the smoke to be more concentrated and the suction experience to be better. The sealing part 211 is embedded in the upper opening of the liquid storage atomizing main body 10 to seal and seal the upper end of the liquid storage cavity 110. In some embodiments, the nozzle body 20 can also include a seal 22 that fits over the blocking portion 211. The sealing member 22 may be made of an elastic material such as silicone, and the sealing member 22 is sealingly disposed between an outer wall surface of the blocking portion 211 and an upper end wall surface of the reservoir 110.

In some embodiments, the nozzle body 20 can be detachably connected to the upper end of the liquid storage atomizing body 10, and on one hand, the liquid substrate can be added to the liquid storage cavity 110 by detaching the nozzle body 20 from the liquid storage atomizing body 10, so as to prolong the service life of the atomizer 100; on the other hand, the parts of the nozzle body 20 and/or the liquid storage and atomization body 10 can be replaced independently, so that the cost is reduced. In other embodiments, the nozzle body 20 and the liquid storing and atomizing body 10 can be connected together in a non-detachable manner.

The reservoir atomizing body 10 may include a housing 11, a vent tube 12, an atomizing assembly 13, an electrode post 14, and a base 16. The vent tube 12 is disposed longitudinally in the housing 11 and may be disposed coaxially with the housing 11. Vent tube 12 may be tubular with an interior wall surface of vent tube 12 defining an outlet passage 120 and an annular reservoir 110 defined between an exterior wall surface of vent tube 12 and an interior wall surface of housing 11. The upper end of the vent tube 12 may be embedded in the nozzle body 20, and specifically, the upper end of the vent tube 12 may pass through the seal 22 and be embedded in the nozzle 21. Wherein the sealing member 22 is used for sealing and wrapping the vent pipe 12, and the suction nozzle 21 is used for ensuring the reliability of the connection between the vent pipe 12 and the suction nozzle main body 20.

The atomizing assembly 13 is accommodated in the vent pipe 12 and may be disposed coaxially with the vent pipe 12. The atomizing assembly 13 includes an atomizing core 130, and the atomizing core 130 includes a liquid 131 and a heating element 132 in contact with the liquid 131. The liquid absorbing body 131 is in liquid-conducting communication with the reservoir chamber 110, and is used for absorbing the liquid matrix from the reservoir chamber 110 and conducting the liquid matrix to the heating body 132. Specifically, in this embodiment, the absorbent body 131 is a porous ceramic that is capable of drawing the liquid matrix from the reservoir 110 by infiltration and capillary action of its internal microporous structure. The liquid absorbent 131 may be cylindrical, and an atomizing chamber 1310 is formed therein and penetrates in the longitudinal direction. The nebulizing chamber 1310 communicates with the lower end of the output channel 120 and may be disposed coaxially with the output channel 120. It is understood that in other embodiments, the liquid absorbent 131 is not limited to porous ceramic materials, and other porous materials may be used.

The heating element 132 may be a heating film, which may be formed on the blank of the liquid absorbent 131 by silk-screen printing, printing or spraying, and then sintered with the liquid absorbent 131; alternatively, the heating element 132 may be a separately formed metal heating sheet or a metal heating wire. The heating element 132 includes at least one heating trace 1321, and the at least one heating trace 1321 may be provided on an inner wall surface of the liquid absorbent 131 to generate heat after being energized, thereby heating and atomizing the liquid substrate adsorbed by the liquid absorbent 131. Further, the heating element 132 may further include end- face electrodes 1322, 1323 and connection electrodes 1324, 1325. The connection electrodes 1324 and 1325 are provided on the upper and lower sides of the inner wall surface of the liquid-absorbent 131, respectively, and the end- face electrodes 1322 and 1323 are provided on the upper and lower end faces of the liquid-absorbent 131, respectively. The upper and lower ends of the heat generating trace 1321 are connected to the end- face electrodes 1322 and 1323 via the connection electrodes 1324 and 1325, respectively, so that an external power source can be externally connected via the connection electrodes 1324 and 1325 or the end- face electrodes 1322 and 1323. It is to be understood that in other embodiments, the heat-generating body 132 may not include the connection electrodes 1324, 1325, or the heat-generating body 132 may not include the end- face electrodes 1322, 1323.

In this embodiment, the heating element 132 includes three heating traces 1321 connected in parallel, and the three heating traces 1321 are uniformly spaced along the circumferential direction of the liquid absorbing body 131, so as to facilitate uniform heating of the liquid substrate absorbed by the liquid absorbing body 131. Each of the heat emitting traces 1321 extends in a non-linear manner, for example, in a curved or zigzag manner in the axial direction of the heat emitting element 132, which is advantageous for increasing the heating area of the heat emitting trace 1321. The two connection electrodes 1324, 1325 are cylindrical, and the two end- face electrodes 1322, 1323 are annular plate-shaped. The upper end of the connection electrode 1324 is connected to the end-face electrode 1322, and the lower end is connected to the upper ends of the three heat generation traces 1321. The lower end of the connection electrode 1325 is connected to the end surface electrode 1323, and the upper end is connected to the lower ends of the three heat generation traces 1321. It is understood that in other embodiments, the number of heating traces 1321 may be one, two, or more than three, and/or heating traces 1321 may also extend along a straight line.

In some embodiments, the atomizing core 130 can further include a wicking cotton 137 that is sleeved outside the liquid 131 and contacts the liquid 131. The liquid matrix in the reservoir 110 is absorbed by the wicking cotton 137 and distributed in the wicking cotton 137, and then is transferred to the absorbent 131, so that the liquid transfer rate is higher, and the liquid transfer is more uniform.

The base 16 is disposed at the lower end of the housing 11 and seals the lower end of the reservoir 110. In some embodiments, both the base 16 and the vent tube 12 may be electrically conductive. The end electrode 1322 may be electrically connected to the vent tube 12, either directly or indirectly, and thus to the base 16. The electrode column 14 is longitudinally disposed through the base 16 and is electrically insulated from the base 16. The end face electrode 1323 is electrically connected to the electrode column 14 directly or indirectly.

In some embodiments, the base 16 may be integrally formed of a metal material and may be fixed in the housing 11 by riveting or the like. The susceptor 16 may include a base 161, an embedding portion 162 extending upward from an upper end of the base 161, and an abutting portion 163 extending downward from a lower end of the base 161. The base 161 may have a cylindrical shape, an upper end surface of the base 161 may abut against a lower end surface of the housing 11, and an outer diameter of the base 161 may coincide with an outer diameter of a lower end of the housing 11. The abutting portion 163 may have a cylindrical shape, and an outer wall surface of the abutting portion 163 is provided with a screw structure for screw connection with the power supply device 200. The outer diameter of the abutment 163 may be smaller than the outer diameter of the base 161. At least one air inlet 1630 is further disposed on the sidewall of the upper portion of the docking portion 163, which is not provided with a thread structure, for allowing outside air to enter the atomizing chamber 1310. In this embodiment, there are a plurality of air inlet holes 1630, and the plurality of air inlet holes 1630 are uniformly distributed along the circumferential direction of the abutting portion 163.

The embedding part 162 may be cylindrical and embedded in the lower portion of the housing 11, and at least a part of the outer peripheral surface of the embedding part 162 is in sealing fit with the inner wall surface of the housing 11 to seal the lower end of the reservoir 110. Specifically, in the present embodiment, the embedding portion 162 may include a body portion 1621 and a sealing boss 1622 extending outwardly from the body portion 1621. The outer wall surface of the body portion 1621 may be clearance fitted with the inner wall surface of the housing 11, and the body portion 1621 has a long length in the axial direction, which may reduce the assembling force required when the base 16 is fitted into the housing 11. The sealing boss 1622 is in interference fit with the inner wall surface of the housing 11, and the sealing effect is enhanced by the interference fit. The axial length of the sealing boss 1622 is short to reduce the force required to assemble the base 16 into the housing 11 while ensuring sealability. In addition, the sealing boss 1622 may be located at the top of the body portion 1621 or near the top of the body portion 1621, so that less liquid matrix may infiltrate between the outer wall surface of the embedding portion 162 and the inner wall surface of the housing 11, and the liquid leakage prevention effect is better. The upper end of the sealing boss 1622 may further be formed with a guide slope 1623, an outer diameter of the guide slope 1623 is gradually reduced from bottom to top, and the outer diameter of the upper end of the guide slope 1623 is smaller than an inner diameter of the housing 11, so that the sealing boss 1622 may be conveniently guided into the housing 11. It will be appreciated that in other embodiments, the outer wall surface of body portion 1621 may also be transition fit with the inner wall surface of housing 11. In other embodiments, the sealing boss 1622 may also be located at a middle or lower portion of the body portion 1621.

Further, the insertion portion 162 may further include a connection portion 1624 connected to a lower end of the body portion 1621. The outer wall surface of the connecting portion 1624 can be in interference fit with the inner wall surface of the housing 11, which can further improve the liquid leakage prevention effect, and can further secure the fixing of the embedding portion 162 in the housing 11. Further, since the embedding portion 162 is located at the opening of the housing 11, it has a small influence on the assembling force required when the base 16 is loaded into the housing 11. It will be appreciated that in other embodiments, a transition fit or a clearance fit may be used between the outer wall surface of connecting portion 1624 and the inner wall surface of housing 11.

In some embodiments, an insulating space 1610 may be further formed on the base 16, and the insulating space 1610 may perform an insulating function, so as to reduce heat transferred from the base 16 to the outside and reduce heat loss. In the present embodiment, the thermal insulation space 1610 is a circular ring-shaped groove formed by an outer circumferential surface of the base 161 being depressed inward in the radial direction. Since the outer diameter of the base 161 is the largest, the heat insulation space 1610 is provided on the base 161, so that the heat insulation space 1610 has a large volume, which improves the heat insulation effect, and reduces the amount of heat transferred to the abutting portion 163, thereby reducing the amount of heat transferred to the power supply device 200.

It is understood that the insulating space 1610 may take other shapes in other embodiments. In some embodiments, the insulation space 1610 may include a plurality of insulation slots spaced apart, which may be circumferentially and/or axially spaced apart along the base 16, e.g., the plurality of insulation slots may be spaced apart in a petaloid pattern. In other embodiments, the insulation space 1610 may also be formed entirely or partially on the embedding portion 162 or the abutting portion 163. In addition, the thermal insulation space 1610 may be filled with a thermal insulation medium to further improve the thermal insulation effect.

In some embodiments, the liquid storage atomizing body 10 may further include a fixing sleeve 17, and the fixing sleeve 17 is cylindrical and is disposed at the lower end of the housing 11 and outside the base 161 to enhance the fixing between the housing 11 and the base 16 and to seal the heat insulation space 1610.

The vent pipe 12 may be integrally formed of a metal material, and may include a first pipe segment 121 and a second pipe segment 122 connected to a lower end of the first pipe segment 121, wherein an inner diameter and an outer diameter of the first pipe segment 121 are smaller than an inner diameter and an outer diameter of the second pipe segment 122. The outer diameter of the first tube segment 121 is small so that the reservoir chamber 110 formed between the outer wall surface of the first tube segment 121 and the inner wall surface of the housing 11 has a large reservoir space. The lower end of the second pipe section 122 is embedded in the base 16, and the outer wall surface of the second pipe section 122 is in contact and communication with the inner wall surface of the base 16. It is understood that in other embodiments, the vent tube 12 and/or the base 16 may be made of conductive or insulating material and then coated with a conductive layer at the desired conductive location to achieve the conductive function.

The atomizing core 130 is accommodated in the second pipe section 122, and at least one inlet 1220 is opened on a side wall of the second pipe section 122, so that the liquid matrix in the reservoir 110 can flow into the atomizing core 130 through the at least one inlet 1220. In this embodiment, there are a plurality of liquid inlets 1220, and the liquid inlets 1220 are uniformly spaced along the circumference of the second tube section 122, so as to facilitate uniform and sufficient liquid supply to the liquid absorber 131. The inner diameter of the second tube section 122 can be slightly smaller than the outer diameter of the liquid guide cotton 137, so that the second tube section 122 can clamp the liquid guide cotton 137, and can fix the atomizing core 130 on one hand and reduce liquid leakage through sealing on the other hand. It is understood that in other embodiments, the inner diameter of the second tube segment 122 may be equal to or greater than the outer diameter of the liquid guide cotton 137.

The upper end of the second pipe segment 122 has an electrically conductive end surface 1221, and the electrically conductive end surface 1221 is directly or indirectly abutted and conducted with the end surface electrode 1322. In this embodiment, the end face 1221 is in direct contact with the end face electrode 1322 and electrically connected thereto.

In some embodiments, the atomizing assembly 13 further includes a conductive connector 135, and the electrode column 14 and the end face electrode 1323 are electrically connected by the conductive connector 135. Further, the electrode column 14 has a conductive end surface 1411, and the conductive connecting member 135 is disposed between the conductive end surface 1411 and the end surface electrode 1323. The conductive connector 135 can include a body portion 1351 and at least one resilient arm 1352 coupled to the body portion 1351, the at least one resilient arm 1352 being in resilient contact with the conductive end surface 1411 or the end surface electrode 1323. The conductive connecting member 135 can elastically deform in the longitudinal direction, so that the atomizing core 130 can elastically float in the longitudinal direction, and when the product consistency is not good, a reliable electrical connection is still formed between the conductive end surface 1411 and the end surface electrode 1323. In addition, since the conductive connection member 135 has elasticity, it is possible to prevent the porous ceramic from being crushed to absorb liquid at the time of mounting.

Specifically, in the present embodiment, the outer wall surface of the electrode column 14 is formed with an annular flange 1412 protruding outward, and the upper end surface of the flange 1412 forms a conductive end surface 1411. The central portion of the top surface of the electrode shaft 14 may be extended downward to form a central hole 140. The central hole 140 is located at the lower portion of the atomizing chamber 1310, and can receive and contain a certain amount of leakage or condensation. The lower end of the central hole 140 has a bottom wall 143, and the bottom wall 143 seals the lower end of the central hole 140 to prevent leakage of liquid or condensate in the central hole 140 to the outside. An annular air gap 144 is formed between the outer wall surface of the electrode column 14 and the inner wall surface of the base 16, and the air inlet hole 1630 is communicated with the atomizing chamber 1310 through the air gap 144. The upper end surface of the electrode column 14 is spaced from the lower end surface of the atomizing core 130, and the spacing serves as heat insulation and gas flow communication. On one hand, the interval can avoid the atomizing core 130 from directly contacting the electrode column 14, and the heat of the atomizing core 130 is prevented from directly transferring to the electrode column 14, thereby being beneficial to heat insulation. On the other hand, this spacing also serves to communicate vent gap 144 with aerosolizing chamber 1310.

As shown in fig. 6, the conductive connection member 135 may be integrally formed of a metal material such as phosphor copper or 316 stainless steel. The surface of the conductive connection member 135 may be further provided with a plating layer such as gold plating or silver plating to improve its conductivity. The main body portion 1351 is cylindrical and is sleeved on the upper portion of the electrode column 14, the lower end of the main body portion 1351 abuts against the conductive end surface 1411 and is in contact conduction with the conductive end surface 1411, and the inner wall surface of the main body portion 1351 is in contact conduction with the outer wall surface of the electrode column 14, so that the conductive connecting member 135 is fixed on the electrode column 14 more firmly, and the electrical connection between the conductive connecting member 135 and the electrode column 14 is more reliable. The bottom of the body portion 1351 may also have a flared structure 1353, the bore of the flared structure 1353 gradually decreasing from bottom to top to facilitate the body portion 1351 to be fitted onto the electrode column 14. In addition, the outer side surface of the upper end of the electrode column 14 may be formed with a guide slope so that the body portion 1351 is fitted over the electrode column 14.

Preferably, the plurality of elastic arms 1352 are arranged at regular intervals along the circumference of the main body portion 1351, and each elastic arm 1352 includes a conduction portion 1355 for elastically abutting against and conducting with the end-face electrode 1323 and a connection arm 1356 for connecting the conduction portion 1355 and the main body portion 1351. In some embodiments, the number of the elastic arms 1352 may be 2 to 4, which can ensure the width of the elastic arms 1352 to make the elastic arms 1352 contact and conduct with the end-face electrode 1323 more stably, and can meet the requirements of the manufacturing process to facilitate the manufacturing process. Specifically, in the present embodiment, the number of the elastic arms 1352 is two.

Further, in the present embodiment, the connecting arm 1356 has a sheet shape and good elasticity, and may extend upward from the top surface of the main body portion 1351 and obliquely toward the center of the main body portion 1351. The conduction part 1355 may have a substantially spoon-shaped structure, and an end of the connection arm 1356 away from the main body part 1351 may be bent towards an inner side of the main body part 1351, that is, a spoon opening is towards an inner side of the main body part 1351. The inclined plane of the spoon-shaped structure has a guiding function, and the bottom of the spoon is an arc surface, so that the spoon can be better contacted with the end face electrode 1323. It will be appreciated that in other embodiments, the connecting arm 1356 can also be angled away from the center of the body portion 1351, and/or the scoop of the conduit 1355 can also be oriented toward the outside of the body portion 1351.

It is to be understood that in other embodiments, the conductive end surface 1411 can also be formed on the upper end surface of the electrode shaft 14. In other embodiments, the main body portion 1351 may be in contact with the end surface electrode 1323, and the elastic arm 1352 may be in elastic contact with the conductive end surface 1411 and be in electrical contact therewith.

As further shown in fig. 3-5, the electrode shaft 14 and the base 16 may be hermetically and insulatively connected by an insulating sleeve 15. Specifically, the insulating sleeve 15 may be made of an insulating material such as silicon gel or plastic, the insulating sleeve 15 is longitudinally disposed in the abutting portion 163, the electrode column 14 is longitudinally disposed in the insulating sleeve 15, and the lower end surface of the flange 1412 may abut against the upper end surface of the insulating sleeve 15. In some embodiments, the insulating sleeve 15 may be in a circular ring shape with an opening at one side, a through hole 150 is formed through the insulating sleeve 15 along the longitudinal direction, and the electrode column 14 is inserted into the through hole 150. A cut-off groove 151 is formed at one circumferential side of the insulating sheath 15, and the cut-off groove 151 penetrates upper and lower sides of the insulating sheath 15 to facilitate the assembly of the electrode shaft 14 into the insulating sheath 15.

Further, at least one air channel 152 may be formed on the insulation cover 15, and the air channel 152 connects the air gap 144 with the outside. In one embodiment, the air channel 152 can be used for air intake, i.e., for the external air to enter the air gap 144, and the air intake holes 1630 may or may not be provided on the base 16. In another embodiment, the air passage 152 may be used to communicate the air gap 144 with an airflow sensor in the power supply device 200, so that the power supply device 200 can be activated to supply power to the nebulizer 100 by the airflow sensor during a puff.

In this embodiment, the air passages 152 are plural and uniformly spaced along the circumference of the insulating sheath 15.
