The atomizing assembly 13 includes an atomizing core 130, and the atomizing core 130 includes a liquid 131 and a heat-generating body 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.

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 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. 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-coupling with the power supply device 200. The outer diameter of the abutment 163 may be smaller than the outer diameter of the base 161.

The upper end surface of the base 16 extends downwards along the longitudinal direction to form a mounting hole 1601 for the air pipe 12 to insert, and the lower end surface of the base 16 extends upwards along the longitudinal direction to form an electrode hole 1603 for the electrode column 14 to penetrate. Electrode hole 1603 is communicated with the lower end of mounting hole 1601, and the aperture of electrode hole 1603 is less than the aperture of mounting hole 1601, makes the bottom of mounting hole 1601 form an annular holding surface 1602. The lower end of the air pipe 12 is accommodated in the mounting hole 1601 and abuts against the support surface 1602, and the outer wall surface of the air pipe 12 is in contact with the hole wall surface of the mounting hole 1601 to communicate therewith. The outer diameter of the electrode column 14 is smaller than the diameter of the electrode hole 1603 so that an annular ventilation gap 144 is formed between the outer wall surface of the electrode column 14 and the inner wall surface of the electrode hole 1603, which ensures electrical insulation between the electrode column 14 and the susceptor 16, while the ventilation gap 144 also has a function of allowing air to flow.

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 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 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 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 sleeved on the lower end of the housing 11 and the outside of the base 161, so as 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 by a metal material, and may include a first pipe segment 121, a second pipe segment 122, and a third pipe segment 123 sequentially connected from top to bottom along an axial direction. The inner diameter and the outer diameter of the first pipe section 121, the second pipe section 122 and the third pipe section 123 are increased in sequence. The outer diameter of the first tube section 121 is minimized so that the reservoir chamber 110 formed between the outer wall surface of the first tube section 121 and the inner wall surface of the housing 11 has a large reservoir space. The third pipe section 123 is fitted into the mounting hole 1601, and an outer wall surface of the third pipe section 123 is in contact with and in communication with a hole wall surface of the mounting hole 1601. It will be appreciated 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.

Atomization assembly 13 is housed in second tube segment 122 and at least a portion of third tube segment 123, and the outer diameter of liquid 131 can be smaller than the inner diameter of second tube segment 122, so that liquid 131 can be conveniently loaded into second tube segment 122, and cracking of liquid 131 caused by excessive squeezing of liquid 131 by second tube segment 122 can be avoided. In other embodiments, the outer diameter of the absorbent body 131 can be equal to the inner diameter of the second tube section 122. At least one inlet port 1220 is formed in a sidewall of second tube segment 122 such that liquid matrix in reservoir chamber 110 can flow into liquid body 131 via the at least one inlet port 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 segment 122, so as to facilitate uniform and sufficient liquid supply to the liquid-absorbing body 131.

The upper end of the second segment 122 has a conductive end surface 1221, and the conductive connecting member 133 is disposed between the conductive end surface 1221 and the end surface electrode 1322, and is abutted against and conducted with the conductive end surface 1221 and the end surface electrode 1322, respectively. The conductive connecting member 133 can elastically deform in the axial direction of the atomizing core 130, so that the atomizing core 130 can elastically float in the axial direction of the second pipe segment 122, and thus when the product consistency is not good, a reliable electrical connection is still formed between the conductive end surface 1221 and the end surface electrode 1322. Further, the atomizing assembly 13 further includes a buffer 134 disposed between the conductive end surface 1221 and the end surface electrode 1322, and the buffer 134 may be made of an insulating elastic material such as silica gel, which can prevent the porous ceramic liquid absorbing material from being crushed during installation.

Specifically, the conductive connecting member 133 may be integrally formed by using a metal material such as phosphor copper or 316 stainless steel. The surface of the conductive connection member 133 may be further provided with a plating layer such as gold plating or silver plating to improve its conductivity. The conductive connector 133 may include a body portion 1331 and at least one elastic arm 1332 connected to the body portion 1331. The main body 1331 is in the shape of a circular ring sheet, and may be disposed between the conductive end surface 1221 and the upper end surface of the buffer 134, and may be in contact with the conductive end surface 1221 and be electrically connected thereto. A plurality of conductive bumps 1333 may also be protrudingly disposed on the upper end surface of the main body portion 1331, the plurality of conductive bumps 1333 are uniformly arranged at intervals along the circumferential direction of the main body portion 1331, and the main body portion 1331 is in contact with the conductive end surface 1221 through the plurality of conductive bumps 1333. Since the sheet-shaped main body 1331 is easily burred during manufacturing, the contact stability between the main body 1331 and the conductive end face 1221 is affected, and the conductive bump 1333 is added, so that reliable electrical connection between the main body 1331 and the conductive end face 1221 can be ensured even when the product consistency is poor. In some embodiments, the number of conductive bumps 1333 may be 2-5.

The plurality of elastic arms 1332 may be provided, and the plurality of elastic arms 1332 are uniformly spaced along the circumference of the main body portion 1331, so that the electrical connection between the plurality of elastic arms 1332 and the end-face electrode 1322 is more reliable. In some embodiments, the number of the elastic arms 1332 may be 2 to 4, which can ensure the width of the elastic arms 1332, so that the elastic arms 1332 can be contacted with the end-face electrode 1322 more stably, and can meet the requirement of the manufacturing process, thereby facilitating the manufacturing. Specifically, in the present embodiment, the number of the elastic arms 1332 and the number of the conductive bumps 1333 are three. Each connecting arm 1336 has a generally U-shaped sheet-like configuration and has good resiliency. The upper arm of the U-shaped plate structure is integrally connected to the outer edge of the main body 1331, and the lower arm is used for elastically abutting against and conducting with the end-face electrode 1322.

The conductive connector 133 at least partially surrounds the buffer 134, and the buffer 134 can also serve as a flexible support for the conductive connector 133. Specifically, the buffer 134 includes a cylindrical sleeve portion 1342 and an annular flange 1341 extending laterally inward from an upper end face of the sleeve portion 1342. The engaging portion 1342 is engaged with an upper portion of the liquid 131 and seals a space between an outer wall surface of the upper portion of the liquid 131 and an inner wall surface of the second pipe section 122. The annular flange 1341 is disposed between the electrically conductive end face 1221 and the end face electrode 1322, and the elastic arm 1332 may wrap around the annular flange 1341 from the inner side of the annular flange 1341.

It is understood that in other embodiments, the conductive connection 133 may be mounted upside down, such that the main body 1331 is in contact with the end face electrode 1322, and the elastic arm 1332 is in elastic contact with and in electrical contact with the conductive end face 1221.

The upper end of the electrode pillar 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, and is respectively abutted against and conducted with the conductive end surface 1411 and 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. Further, the atomizing assembly 13 further includes a buffer member 136, and the buffer member 136 may be made of an insulating elastic material such as silicon gel. The conductive connector 135 at least partially encloses the buffer member 136, and the buffer member 136 can serve to flexibly support the conductive connector 135.

The conductive connector 135 includes a main body portion 1351 and at least one elastic arm 1352 connected to the main body portion 1351, wherein a plurality of conductive bumps 1353 may protrude from an upper end surface of the main body portion 1351, the main body portion 1351 is in contact with the end surface electrode 1323 via the plurality of conductive bumps 1353, and the at least one elastic arm 1352 is in elastic contact with and in contact with the conductive end surface 1411. The structure of the conductive connecting element 135 is the same as that of the conductive connecting element 133, and reference may be made to the above description of the conductive connecting element 133, which is not repeated herein. The conductive connecting member 135 and the conductive connecting member 133 have the same structure and can be used in common, so that the assembly difficulty can be reduced, the mass production is facilitated, and the cost is reduced.

It is understood that in other embodiments, the conductive connector 135 can be mounted upside down, such that the main body portion 1351 is in electrical contact with the conductive end surface 1411, and the elastic arms 1352 are in electrical contact with the end surface electrode 1323.

The damper 136 may be in the shape of a circular cylinder and is received in the third tube segment 123, and a mounting hole 1360 is formed in the damper 136 along the longitudinal direction and communicates with the atomizing chamber 1310. The lower end of the liquid absorbent 131 can be fitted into the mounting hole 1360, and on the one hand, the liquid absorbent 131 can be flexibly clamped and fixed, and on the other hand, leakage of liquid can be prevented by the sealing engagement between the outer wall surface of the liquid absorbent 131 and the hole wall surface of the mounting hole 1360 and the sealing engagement between the outer wall surface of the buffer member 136 and the inner wall surface of the third tube section 123.

The hole wall surface of the mounting hole 1360 may be formed with an annular flange 1361 extending in the lateral direction, and the annular flange 1361 is provided between the conductive end surface 1411 and the end surface electrode 1323, so that the porous ceramic liquid absorbent can be prevented from being crushed at the time of mounting. In the present embodiment, the body portion 1351 abuts against the upper end surface of the annular flange 1361. The elastic arms 1352 can be snap-fitted from the inner side of the annular flange 1361 and wrap around the annular flange 1361, and the upper and lower side arms of the elastic arms 1352 can respectively abut against the upper and lower end surfaces of the annular flange 1361. The upper end of the electrode column 14 abuts against the lower end face of the annular flange 1361 through the conduction portion 1355.

Further, the electrode column 14 and the base 16 can be connected in an insulation and sealing manner through an insulation sleeve 15. Specifically, the electrode column 14 may include a first cylinder 141 and a second cylinder 142 connected to a lower end of the first cylinder 141, and an outer diameter of the first cylinder 141 is greater than an outer diameter of the second cylinder 142. In other embodiments, the outer diameter of the first cylinder 141 may also be equal to or less than the outer diameter of the second cylinder 142. The insulating sleeve 15 may be made of silica gel or plastic material, the insulating sleeve 15 is longitudinally disposed in the electrode hole 1603, the second cylinder 142 is longitudinally disposed in the insulating sleeve 15, and the lower end surface of the first cylinder 141 may abut against the upper end surface of the insulating sleeve 15. In some embodiments, the insulating sleeve 15 may be in the shape of a circular ring 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.

In some embodiments, the central portion of the top surface of the electrode shaft 14 may be extended downward to form a central hole 140, and the central hole 140 is located at the lower portion of the atomizing chamber 1310 and communicates with 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 to the outside. At least one air inlet 1412 is further formed on the sidewall of the first cylinder 141, at least one air inlet 1630 is further formed on the sidewall of the upper portion of the abutting portion 163, which is not provided with a thread structure, a ventilation gap 144 is formed between the outer wall surface of the first cylinder 141 and the hole wall surface of the electrode hole 1603, and the external air can enter the atomizing chamber 1310 through the air inlet 1630, the ventilation gap 144, the air inlet 1412 and the central hole 140 in sequence. In this embodiment, there are a plurality of

air inlets

1412 and 1630, respectively, the plurality of air inlets 1412 are uniformly spaced along the circumferential direction of the first cylinder 141, and the plurality of air inlets 1630 are uniformly spaced along the circumferential direction of the abutting portion 163.

In some embodiments, the insulation cover 15 may further have at least one air channel 152 formed thereon, and the at least one 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 channel 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 power the nebulizer 100 via 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. Each of the air passages 152 includes an air vent 1521 formed on an upper end surface of the insulating sleeve 15 and an air groove 1522 communicating with the air vent 1521 and formed on an inner wall surface of the insulating sleeve 15 in a longitudinal direction. It is understood that in other embodiments, the air channel 152 can be formed on the outer wall surface of the insulation sleeve 15.

In some embodiments, at least one ventilation channel 164 is formed between the inner wall of the base 16 and the outer wall of the vent pipe 12 to communicate the reservoir 110 with the outside for balancing the pressure in the reservoir 110, thereby solving the problem that the liquid cannot be stably discharged due to excessive negative pressure in the reservoir 110. The ventilation channel 164 may be in communication with the ventilation gap 144 and further in communication with the ambient via the air inlet holes 1630 and/or the ventilation channel 152.

Specifically, in the present embodiment, the ventilation passage 164 has two and is formed in the inner wall surface of the base 16. The two ventilation channels 164 are straight channels extending in the longitudinal direction and are respectively located on two circumferentially opposite sides of the mounting hole 1601. Each of the ventilation channels 164 includes a ventilation opening 1641 formed in the support surface 1602 and a main channel 1642 communicating the ventilation opening 1641 with the reservoir chamber 110. The ventilation opening 1641 may be formed by the support surface 1602 being recessed, and the main channel 1642 may extend longitudinally upward from the ventilation opening 1641 to the upper end surface of the mounting hole 1601. It is understood that in other embodiments, the ventilation channel 164 may have a linear shape extending obliquely, i.e., the ventilation channel 164 may extend in a direction not parallel to the axial direction of the ventilation tube 12. In other embodiments, the ventilation channels 164 may be non-linear channels, and/or the number of ventilation channels 164 may be one, two, or more.

The cross-sectional dimension of the ventilation channel 164 (e.g., the width, depth, cross-sectional area, etc. of the ventilation channel 164) is set to be reasonable, so that the liquid medium has a large on-way resistance in the ventilation channel 164 to cause liquid leakage through the ventilation channel 164, and the on-way resistance of the gas in the ventilation channel 164 is small to allow ventilation through the ventilation channel 164, thereby ensuring that the ventilation channel 164 has a good gas and liquid guiding and blocking function. When a user sucks, when a new release space which is not filled with the liquid matrix is generated in the liquid storage cavity 110 due to consumption of the liquid matrix, the external air enters the liquid storage cavity 110 through the ventilation channel 164 to fill the release space, so that the phenomenon that the liquid in the liquid storage cavity 110 is unsmooth due to the fact that the air pressure in the liquid storage cavity 110 is smaller than the external air pressure is avoided, and dry burning of the atomizing core 130 due to the fact that the consumption speed of the liquid matrix is larger than the supply speed is prevented.

Fig. 6 shows an alternative embodiment of the base 16, which differs from the first embodiment described above in that the ventilation channel 164 in this embodiment is helical; the ventilation opening 1641 of the ventilation channel 164 is formed by the support surface 1602 being recessed; the main channel 1642 has a spiral shape, one end of which communicates with the ventilation opening 1641 and the other end of which is spirally wound to the upper end surface of the mounting hole 1601. The number of the ventilation channels 164 may be one, two, or more than two.

Fig. 7 shows an alternative embodiment of the ventilation tube 12 of the present invention, which differs from the first embodiment described above in that the ventilation channel 164 in this embodiment is formed by a depression in the outer wall surface of the ventilation tube 12. Specifically, in the present embodiment, the lower end of the ventilation pipe 12 has a receiving section 1232 received in the mounting hole 1601, and the ventilation channel 164 is formed by recessing the outer wall surface of the receiving section 1232. The ventilation channel 164 has a substantially zigzag shape, which may include two longitudinally extending and spaced

longitudinal channels

1643 and 1645 and a communication channel 1644 connecting the two

longitudinal channels

1643 and 1645. The lower end of the longitudinal passage 1643 communicates with the vent gap 144, which may extend upwardly a distance from the outer wall of the lower end of the vent tube 12. The lower end of the longitudinal passage 1645 is communicated with the communication passage 1644, and the upper end is communicated with the liquid storage cavity 110.

It is understood that in other embodiments, the number of the ventilation channels 164 may be one, two or more, and/or the shape of the ventilation channels 164 may be linear or non-linear. The straight line shape may include various shapes such as a zigzag shape, a curved shape (e.g., an S-shape or an arc shape), a spiral shape, and the like.

Fig. 8 to 9 show a nebulizer 100 according to a second embodiment of the invention, which is different from the first embodiment described above in that a ventilation passage 164 in the present embodiment is formed between the outer wall surface of the base 16 and the inner wall surface of the housing 11.

Specifically, in the present embodiment, the ventilation channel 164 is formed by an outer wall surface of the base 16 being concave. The ventilation channel 164 may have a linear shape extending in the longitudinal direction, and may extend from the upper end surface of the embedding portion 162 to the lower end surface of the base portion 161 in the longitudinal direction. The upper end of the ventilation channel 164 is in direct communication with the reservoir 110 and the lower end is in direct communication with the outside atmosphere.

It is understood that, in other embodiments, the ventilation channel 164 may be formed by a recess on the inner wall surface of the housing 11, and/or the number of the ventilation channels 164 may be one, two or more, and/or the ventilation channel 164 may have various shapes such as a straight line shape, a zigzag line shape or a curved line shape (e.g., S-shaped, arc-shaped or spiral shape).

In addition, the atomizing assembly 13 in this embodiment further includes a liquid guide cotton 137 sleeved outside the liquid absorption 131 and contacting the liquid absorption 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.

Further, in the present embodiment, the vent pipe 12 includes only the first pipe segment 121 and the second pipe segment 122 connected to the lower end of the first pipe segment 121, and the inner diameter and the outer diameter of the first pipe segment 121 are smaller than those of the second pipe segment 122, respectively. Atomizing assembly 13 is received in second tube segment 122. The inner diameter of the second pipe section 122 may be slightly smaller than the outer diameter of the liquid guide cotton 137, so that the second pipe section 122 can clamp the liquid guide cotton 137, on one hand, the atomization assembly 13 can be fixed, and on the other hand, leakage can be reduced through sealing. 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.
