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. It is understood that, in other embodiments, the nebulizer 100 and the power supply device 200 may be connected together in other detachable manners, such as a magnetic attraction connection, a snap connection, or the nebulizer 100 and the power supply device 200 may be connected together in a non-detachable manner. The cross-sectional shape of the atomizer 100 and/or the power supply device 200 is not limited to a circular shape, and may be another shape such as an oval shape, a racetrack shape, or 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. The liquid storage and atomization body 10 is formed with a liquid storage cavity 110 for containing a liquid substrate and an output channel 120 isolated from the liquid storage cavity 110 for delivering aerosol.

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 section 212 may have a flat shape, and the flat shape design can better fit the lips, and enables the smoke to be more concentrated, and the suction experience is 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 reservoir 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 longitudinally disposed 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 wicking fluid 131 is in fluid communication with the reservoir 110 for wicking the liquid matrix from the reservoir 110 and conducting the liquid matrix to the heater 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 two end-

face electrodes

1322, 1323 connected to both poles of the at least one heating trace 1321. The at least one heat emitting trace 1321 may be provided on an inner wall surface of the liquid absorbent 131, and is configured to emit heat after being energized, thereby heating and atomizing the liquid substrate adsorbed by the liquid absorbent 131. The two

end surface electrodes

1322 and 1323 are respectively disposed on the upper end surface and the lower end surface of the liquid absorber 131, and are used for externally connecting an external power supply. Further, in some embodiments, the heating element 132 may further include two

connection electrodes

1324, 1325, the two

connection electrodes

1324, 1325 are respectively disposed at the upper and lower ends of the inner wall surface of the liquid absorbent 131, and the upper and lower ends of the heating trace 1321 are respectively connected to the two

end surface electrodes

1322, 1323 through the two

connection electrodes

1324, 1325. It is to be understood that, in other embodiments, the heating element 132 may not include the two connecting

electrodes

1324, 1325, that is, the upper and lower ends of the heating trace 1321 may be directly connected to the two

end surface 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 be beneficial to uniformly heating 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, heat emitting trace 1321 may be one, two, or more than three in number, and/or heat emitting trace 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 liquid storage cavity 110 is absorbed by the liquid guide cotton 137 and is distributed in the liquid guide cotton 137, and then is guided to the liquid absorption body 131, so that the liquid guide speed is higher, and the liquid guide 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 snorkel 12, and thus the base 16, either directly or indirectly. 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 interface 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 air inlet holes 1630 are uniformly distributed along the circumferential direction of the docking portion 163.

The embedding portion 162 may be cylindrical and embedded in the lower portion of the housing 11, and at least a portion of the outer peripheral surface of the embedding portion 162 is in sealing fit with the inner wall surface of the housing 11 to seal and block 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 susceptor 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 disposed at the top of the body portion 1621 or near the top of the body portion 1621, so that less liquid medium 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 preventing 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 in the 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 the connecting portion 1624 and the inner wall surface of the housing 11.

In some embodiments, an insulating space 1610 may be further formed on the base 16, and the insulating space 1610 may perform the functions of insulating and preserving heat, so as to reduce the amount of heat transferred from the base 16 to the outside and reduce heat loss. In this embodiment, the 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 base 161 has the largest outer diameter, the heat insulation space 1610 is provided on the base 161, so that the heat insulation space 1610 has a large volume to improve the heat insulation effect, and the amount of heat transferred to the abutting portion 163 and the power supply device 200 can be reduced. It is understood that in other embodiments, the insulation space 1610 may have other shapes, such as a petal shape arranged at intervals. In other embodiments, the insulation space 1610 may also be formed in whole or in part on the embedding portion 162 or the abutting portion 163. In addition, the thermal insulation space 1610 may be filled with thermal insulation material 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, and the first pipe segment 121 has an inner diameter and an outer diameter smaller than those 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 may 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 thus 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 connector 135 has elasticity, it is possible to prevent the porous ceramic from crushing and absorbing liquid when it is mounted.

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 to provide thermal insulation and air flow communication. On one hand, the space can prevent the atomizing core 130 from directly contacting the electrode column 14, and prevent the heat of the atomizing core 130 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 portion 1355 may have a substantially spoon-shaped structure, and an end of the connection arm 1356 away from the main body portion 1351 is bent toward an inner side of the main body portion 1351, i.e., a spoon opening is toward an inner side of the main body portion 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.
