BACKGROUND

[0003] An electronic vaporization device is configured to heat and vaporize a vaporizable liquid medium to generate inhalable aerosols. The electronic vaporization device generally includes a vaporizer and a power supply device. The vaporizer is configured to accommodate the liquid medium, and heat and vaporize the liquid medium after being powered on. The power supply device is configured to supply power to the vaporizer.

[0004] When the vaporizer vaporizes the liquid medium, air pressure in the liquid storage cavity is reduced as the liquid medium is consumed. This results in inadequate liquid supply to a vaporization core, so that the liquid medium fails to be quickly replenished to the vaporization core. Consequently, dry heating of the vaporization core is caused dry heats, resulting in damage to the vaporization core due to the poor liquid supply, a burnt smell, and harmful substances.

[0040] FIG. 1 to FIG. 2 shows an electronic vaporization device 1 in a first embodiment of the present disclosure. The electronic vaporization device 1 includes a vaporizer 100 and a power supply device 200 matched with and connected to the vaporizer 100. The power supply device 200 is configured to supply power to the vaporizer 100, and may control operations such as opening and closing of the entire electronic vaporization device 1. The vaporizer 100 is configured to accommodate a liquid medium and heat and vaporize the liquid medium after being powered on to generate aerosols. In some embodiments, both the vaporizer 100 and the power supply device 200 may be substantially cylindrical, and may be mechanically and electrically connected axially. Further, the vaporizer 100 and the power supply device 200 may be detachably connected together in a threaded connection manner. It may be understood that in other embodiments, the vaporizer 100 and the power supply device 200 may alternatively be connected together in another detachable manner, such as by magnetic connection or snap -Date Recue/Date Received 2023-07-13 fit connection, or the vaporizer 100 and the power supply device 200 may alternatively be connected together in a non-detachable manner. In addition, the cross-sectional shape of the vaporizer 100 and/or the power supply device 200 is not limited to being circular, and may alternatively be in other shapes, such as oval, racetrack, or rectangular.

[0041] As shown in FIG. 3 to FIG. 5, the vaporizer 100 may include a liquid storage and vaporization body 10 and a mouthpiece body 20 disposed at the upper end of the liquid storage and vaporization body 10. A liquid storage cavity 110 for accommodating a liquid medium and an output channel 120 separated from the liquid storage cavity 110 and configured to deliver aerosols are formed in the liquid storage and vaporization body 10. The mouthpiece body 20 is blocked at the upper end of the liquid storage cavity 110, and has a vaping channel 210 communicated with the output channel 120 formed therein.

[0042] Specifically, the mouthpiece body 20 may include a mouthpiece 21.
The vaping channel 210 is formed in the mouthpiece 21 in the longitudinal direction and may be disposed coaxially with the mouthpiece 21. In some embodiments, the mouthpiece 21 may be made of a hard material such as plastic, to improve structural stability of the vaping channel 210. Further, the mouthpiece 21 may include a blocking part 211 located at the lower part and a mouthpiece part 212 at the upper part. The mouthpiece part 212 may have a flat shape. The flat design can better fit lips, and can better gather vapor to improve vaping experience. The blocking part 211 is inserted in an opening at the upper end of the liquid storage and vaporization body 10, to sealingly block the upper end of the liquid storage cavity 110. In some embodiments, the mouthpiece body 20 may further include a seal member 22 fitted outside the blocking part 211.

[0043] The seal member 22 may be made of an elastic material such as silica gel. The seal member 22 is disposed between the outer wall surface of the blocking part 211 and the cavity wall surface of the upper end of the liquid storage cavity 110 in a sealed manner.

[0044] In some embodiments, the mouthpiece body 20 may be detachably connected to the upper end of the liquid storage and vaporization body 10. In this way, the liquid medium can be added to the liquid storage cavity 110 by detaching the mouthpiece body 20 from the liquid storage and vaporization body 10, to prolong the service life of the vaporizer 100. In addition, parts of the mouthpiece body 20 and/or the liquid storage and vaporization body 10 can be replaced separately, to reduce costs. In other embodiments, the mouthpiece body 20 and the Date Recue/Date Received 2023-07-13 liquid storage and vaporization body 10 may alternatively be connected together in a non-detachable manner.

[0045] The liquid storage and vaporization body 10 may include a shell 11, a vent tube 12, a vaporization assembly 13, an electrode column 14 and abase 16. The vent tube 12 is disposed in the shell 11 in the longitudinal direction and may be disposed coaxially with the shell 11.
The vent tube 12 may be tubular. The inner wall surface of the vent tube 12 defines an output channel 120. An annular liquid storage cavity 110 is defined between the outer wall surface of the vent tube 12 and the inner wall surface of the shell 11. The upper end of the vent tube 12 may be inserted into the mouthpiece body 20. Specifically, the upper end of the vent tube 12 may penetrate through the seal member 22 and be inserted into the mouthpiece 21. The seal member 22 is configured to sealingly wrap on the vent tube 12. The mouthpiece 21 is used for ensuring the reliability of the connection between the vent tube 12 and the mouthpiece body 20.

[0046] The vaporization assembly 13 is accommodated in the vent tube 12 and may be disposed coaxially with the vent tube 12. The vaporization assembly 13 includes a vaporization core 130. The vaporization core 130 includes a liquid absorbing element 131 and a heating element 132 in contact with the liquid absorbing element 131. The liquid absorbing element 131 is in fluid communication with the liquid storage cavity 110, and is configured to absorb the liquid medium from the liquid storage cavity 110 and deliver the liquid medium to the heating element 132. Specifically, in this embodiment, the liquid absorbing element 131 is a porous ceramic, and can absorb the liquid medium from the liquid storage cavity 110 through infiltration and capillary effect of an internal microporous structure of the liquid absorbing element. The liquid absorbing element 131 may be cylindrical, and is internally provided with a vaporization cavity 1310 running through the liquid absorbing element in the longitudinal direction. The vaporization cavity 1310 is communicated with the lower end of the output channel 120 and may be disposed coaxially with the output channel 120. It may be understood that in other embodiments, the liquid absorbing element 131 may alternatively be made of other porous materials, not limited to a porous ceramic material.

[0047] The heating element 132 may be a heating film, and may be formed on a blank of the liquid absorbing element 131 by silk screen printing, printing, spraying or the like, then sintered together with the liquid absorbing element 131 and formed.
Alternatively, the heating element 132 may be an independently formed metal heating sheet or metal heating wire. The Date Recue/Date Received 2023-07-13 heating element 132 includes at least one heating track 1321. The at least one heating track 1321 may be disposed in the inner wall surface of the liquid absorbing element 131 and is configured to generate heat after being energized, so as to heat and vaporize the liquid medium absorbed by the liquid absorbing element 131. In this embodiment, the heating element 132 includes three parallel heating tracks 1321. The three heating tracks 1321 are evenly arranged at intervals in the circumferential direction of the liquid absorbing element 131. This is beneficial to uniformly heat the liquid medium adsorbed by the liquid absorbing element 131.
Each heating track 1321 extends in the axial direction of the heating element 132 in a non-linear manner, such as extending along a curved or zigzag path, to increase the heating area of the heating track 1321. It may be understood that in other embodiments, the quantity of the heating tracks 1321 may be one, two, or three or more, and/or, the heating tracks 1321 may also extend along a straight line.

[0048] The base 16 is disposed at the lower end of the shell 11 and blocks the lower end of the liquid storage cavity 110. The electrode column 14 is inserted into the base 16 in the longitudinal direction and is electrically insulated from the base 16. In some embodiments, both the base 16 and the vent tube 12 are electrically conductive. One pole of the heating element 132 may be directly or indirectly electrically connected to the vent tube 12, so as to be electrically connected to the base 16. Another pole of the heating element 132 may be directly or indirectly electrically connected to the electrode column 14.

[0049] In this embodiment, the upper end of the heating element 132 is electrically connected to the vent tube 12 through a conductive connector 133. The lower end of the heating element 132 is electrically connected to the electrode column 14 through a conductive connector 135. Further, the heating element 132 further includes two end surface electrodes 1322 and 1323 and two connection electrodes 1324 and 1325. The two connection electrodes 1324 and 1325 are respectively disposed at the upper and lower ends of the inner wall surface of the liquid absorbing element 131. The upper and lower ends of the heating track 1321 are respectively connected to the two end surface electrodes 1322 and 1323 through the two connection electrodes 1324 and 1325. The two end surface electrodes 1322 and 1323 are electrically connected to the vent tube 12 and the electrode column 14 via the conductive connectors 133 and 135, respectively.

[0050] The two connection electrodes 1324 and 1325 are cylindrical. The two end surface electrodes 1322 and 1323 are thin annular discs. The upper end of the connection electrode Date Recue/Date Received 2023-07-13 1324 is connected to the end surface electrode 1322, and the lower end is connected to the upper ends of the three heating tracks 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 end of the three heating tracks 1321. It may be understood that in other embodiments, the heating element 132 may alternatively not include the two connection electrodes 1324 and 1325. In other words, the upper and lower ends of the heating track 1321 may alternatively be directly connected to the two end surface electrodes 1322 and 1323. In some other embodiments, the heating element 132 may alternatively not include the two end surface electrodes 1322 and 1323. Accordingly, the conductive connectors 133 and 135 are respectively connected to the two connection electrodes 1324 and 1325.

[0051] In some embodiments, the base 16 may be integrally formed by a metal material, and may be fixed in the shell 11 by riveting or the like. The base 16 may include a base part 161, an inserting part 162 extending upward from the upper end surface of the base part 161, and a connecting part 163 extending downward from the lower end surface of the base part 161.
The base part 161 may be cylindrical. The upper end surface of the base part 161 may abut against the lower end surface of the shell 11. The outer diameter of the base part 161 may be the same as the outer diameter of the lower end of the shell 11. The inserting part 162 may be cylindrical and inserted into the lower part of the shell 11. At least part of the outer peripheral surface of the inserting part 162 is sealingly fitted to the inner wall surface of the shell 11, to sealingly block the lower end of the liquid storage cavity 110. The connecting part 163 may be cylindrical. The outer wall surface of the connecting part 163 is provided with a threaded structure for threaded connection with the power supply device 200. The outer diameter of the connecting part 163 may be smaller than the outer diameter of the base part 161.

[0052] The upper end surface of the base 16 extends longitudinally downward to form a mounting hole 1601 allowing for insertion of the vent tube 12. The lower end surface of the base 16 extends longitudinally upward to form an electrode hole 1603 allowing the electrode column 14 to pass through. The electrode hole 1603 is in communication with the lower end of the mounting hole 1601, and the diameter of the electrode hole 1603 is smaller than the diameter of the mounting hole 1601, so that an annular support surface 1602 is formed at the bottom of the mounting hole 1601. The lower end of the vent tube 12 may be accommodated in the mounting hole 1601 and abut against the support surface 1602. The outer wall surface of the vent tube 12 is in electrical contact with the hole wall surface of the mounting hole 1601.

Date Recue/Date Received 2023-07-13 The outer diameter of the electrode column 14 is smaller than the diameter of the electrode hole 1603, so that an annular vent gap 144 is formed between the outer wall surface of the electrode column 14 and the inner wall surface of the electrode hole 1603. In this way, electric insulation between the electrode column 14 and the base 16 can be guaranteed.
In addition, the vent gap 144 also has a function of allowing airflow circulation.

[0053] In some embodiments, a heat insulation space 1610 may also be formed on the base 16. The heat insulation space 1610 can play a role of heat insulation and heat preservation, to reduce heat transferred outward by the base 16 and reduce heat loss. In this embodiment, the heat insulation space 1610 is an annular groove, which is formed by radial inward recession of the outer peripheral surface of the base part 161. Because the outer diameter of the base part 161 is the largest, the provision of the heat insulation space 1610 on the base part 161 enables the heat insulation space 1610 to have large volumetric space, so as to improve heat insulation effect and reduce heat transferred to the connecting part 163, thereby reducing heat transferred to the power supply device 200. It may be understood that in other embodiments, the heat insulation space 1610 may alternatively be in other shapes, such as a shape of petals arranged at intervals. In some other embodiments, the heat insulation space 1610 may alternatively be wholly or partially formed on the inserting part 162 or the connecting part 163. In addition, the heat insulation space 1610 may also be filled with heat insulation materials to further improve the heat insulation effect.

[0054] In some embodiments, the liquid storage and vaporization body 10 may also include a fixing sleeve 17. The fixing sleeve 17 is cylindrical and fitted at the lower end of the shell 11 and outside the base part 161. This can strengthen the fixation between the shell 11 and the base 16, and can also seal the heat insulation space 1610.

[0055] The vent tube 12 may be integrally formed by a metal material, and may include a first tube section 121, a second tube section 122, and a third tube section 123 sequentially connected from top to bottom in the axial direction. The inner and outer diameters of the first tube section 121, the second tube section 122, and the third tube section 123 are sequentially increased. The outer diameter of the first tube section 121 is the smallest, so that the liquid storage cavity 110 formed between the outer wall surface of the first tube section 121 and the inner wall surface of the shell 11 has a large liquid storage space. The third tube section 123 is inserted into the mounting hole 1601. The outer wall surface of the third tube section 123 is in electrical contact with the hole wall surface of the mounting hole 1601. It may be understood Date Recue/Date Received 2023-07-13 that in other embodiments, the vent tube 12 and/or the base 16 may alternatively be made of an electrically conductive or insulating material, and then coated with an electrically conductive layer on a required electrically conductive part to achieve an electrically conductive function.

[0056] The vaporization assembly 13 is accommodated in the second tube section 122 and at least part of the third tube section 123, and the outer diameter of the liquid absorbing element 131 may be smaller than the inner diameter of the second tube section 122, so as to facilitate mounting of the liquid absorbing element 131 into the second tube section 122, thereby preventing the liquid absorbing element 131 from cracking due to excessive squeezing of the liquid absorbing element 131 by the second tube section 122. In other embodiments, the outer diameter of the liquid absorbing element 131 may alternatively be equal to the inner diameter of the second tube section 122. At least one liquid inlet 1220 is provided in the side wall of the second tube section 122, so that the liquid medium in the liquid storage cavity 110 can flow into the liquid absorbing element 131 through the at least one liquid inlet 1220. In this embodiment, there are a plurality of liquid inlets 1220, and the plurality of liquid inlets 1220 are evenly arranged at intervals in the circumferential direction of the second tube section 122, to facilitate uniform and sufficient liquid supply to the liquid absorbing element 131.

[0057] The upper end of the second tube section 122 has a conductive end surface 1221.
The conductive connector 133 is disposed between the conductive end surface 1221 and the end surface electrode 1322, and abuts against and is electrically connected to the conductive end surface 1221 and the end surface electrode 1322 separately. The conductive connector 133 can produce certain elastic deformation in the axial direction of the vaporization core 130, so that the vaporization core 130 can elastically float to a certain extent in the axial direction of the second tube section 122. Therefore, when product uniformity is not satisfactory, a reliable electrical connection is still formed between the conductive end surface 1221 and the end surface electrode 1322. Further, the vaporization assembly 13 also includes a buffer element 134 disposed between the conductive end surface 1221 and the end surface electrode 1322. The buffer element 134 may be made of an elastic insulation material such as silicone, and can prevent damage to the porous ceramic liquid absorbing element during mounting.

[0058] Specifically, the conductive connector 133 may be integrally formed by a metal material such as phosphor bronze or 316 stainless steel. The surface of the conductive connector 133 may also be provided with a coating layer such as a gold coating or a silver Date Recue/Date Received 2023-07-13 coating, to improve conductivity. The conductive connector 133 may include a body part 1331 and at least one elastic arm 1332 connected to the body part 1331. The body part 1331 is a thin annular disc, and may be disposed between the conductive end surface 1221 and the upper end surface of the buffer element 134, and abuts against and is electrically connected to the conductive end surface 1221. A plurality of conductive bumps 1333 may also protrude from the upper end surface of the body part 1331. The plurality of conductive bumps 1333 are arranged at even intervals in the circumferential direction of the body part 1331. The body part 1331 is in electrical contact with the conductive end surface 1221 via the plurality of conductive bumps 1333. Because burrs are likely to be generated during manufacturing of the disc-shaped body part 1331, the contact stability between the body part 1331 and the conductive end surface 1221 will be affected. By adding the conductive bumps 1333, reliable electrical connection between the body part 1331 and the conductive end surface 1221 can be ensured when product uniformity is not satisfactory. In some embodiments, the quantity of the conductive bumps 1333 may be 2 to 5.

[0059] There may be a plurality of elastic arms 1332. The plurality of elastic arms 1332 are arranged at even intervals in the circumference of the body part 1331, so that the electrical connections between the plurality of elastic arms 1332 and the end surface electrode 1322 are more reliable. In some embodiments, the quantity of the elastic arms 1332 may range from two to four. This can ensure the width of the elastic arms 1332 to enable the elastic arms 1332 to be in contact with the end surface electrode 1322 more stably, and can meet requirements of a manufacturing process and facilitate manufacturing. Specifically, in this embodiment, the quantities of the elastic arms 1332 and the conductive bumps 1333 are three.
Each connecting arm 1336 has a roughly U-shaped sheet structure and good elasticity. The upper arm of the U-shaped sheet structure is integrally connected to the outer edge of the body part 1331. The lower arm is configured to elastically abut against and be electrically connected to the end surface electrode 1322.

[0060] The conductive connector 133 at least partially wraps the buffer element 134, and the buffer element 134 can also achieve a function of flexibly supporting the conductive connector 133. Specifically, the buffer element 134 includes a cylindrical sleeve part 1342 and an annular flange 1341 extending transversely and inwardly from the upper end surface of the sleeve part 1342. The sleeve part 1342 can be fitted to the upper part of the liquid absorbing element 131 and seal the upper outer wall surface of the liquid absorbing element 131 and the Date Recue/Date Received 2023-07-13 inner wall surface of the second tube section 122. The annular flange 1341 is disposed between the conductive end surface 1221 and the end surface electrode 1322. The elastic arms 1332 may be wrapped around the annular flange 1341 from the inner side of the annular flange 1341.

[0061] It may be understood that in other embodiments, the conductive connector 133 may alternatively be mounted upside down, so that the body part 133 1 abuts against and is electrically connected to the end surface electrode 1322, and the elastic arms 1332 abut against and are electrically connected to the conductive end surface 1221.

[0062] The upper end of the electrode column 14 has a conductive end surface 1411. The conductive connector 135 is disposed between the conductive end surface 1411 and the end surface electrode 1323, and abuts against and is electrically connected to the conductive end surface 1411 and the end surface electrode 1323 respectively.

In this embodiment, there are a plurality of air inlets 1412 and a plurality of air inlet holes 1630.
The plurality of air inlets 1412 are arranged at even intervals along the circumference of the first column 141. The plurality of air inlet holes 1630 are arranged at even intervals along the circumference of the connecting part 163.

[0070] In some embodiments, at least one vent passage 152 may be formed on the insulating sleeve 15, and the at least one vent passage 152 communicates the vent gap 144 with the outside. In one embodiment, the vent passage 152 may be used for inflow of air, that is, allowing outside air to enter the vent gap 144. In this case, an air inlet hole 1630 may or may not be provided on the base 16. In another embodiment, the vent passage 152 may be configured to communicate the vent gap 144 with an airflow sensor in the power supply device 200, to enable the power supply device 200 to be turned on through the airflow sensor to supply power to the vaporizer 100 during vaping.

[0071] In this embodiment, there are a plurality of vent passages 152 evenly arranged at intervals in the circumferential direction of the insulating sleeve 15. Each vent passage 152 includes a vent slot 1521 formed in the upper end surface of the insulating sleeve 15 and a vent groove 1522 communicated with the vent slot 1521 and formed in the longitudinal direction in Date Recue/Date Received 2023-07-13 the inner wall surface of the insulating sleeve 15. It may be understood that in other embodiments, The vent passages 152 may alternatively be formed on the outer wall surface of the insulating sleeve 15.

[0072] In some embodiments, at least one vent channel 164 communicating the liquid storage cavity 110 with the outside is formed between the inner wall surface of the base 16 and the outer wall surface of the vent tube 12, to balance pressure in the liquid storage cavity 110 and resolve a problem of unsteady liquid delivery due to excessive negative pressure in the liquid storage cavity 110. The vent channel 164 may be communicated with the vent gap 144 and further be communicated with the outside via the air inlet hole 1630 and/or the vent passages 152.

[0073] Specifically, in this embodiment, there are two vent channels 164 formed on the inner wall surface of the base 16. The two vent channels 164 are linear channels extending longitudinally and are respectively located on the two opposite sides of the circumference of the mounting hole 1601. Each of the vent channels 164 includes an air vent 1641 formed on the support surface 1602 and a main channel 1642 communicating the air vent 1641 with the liquid storage cavity 110. The air vent 1641 may be formed by downward recession of the support surface 1602. The main channel 1642 may extend longitudinally upward from the air vent 1641 to the upper end surface of the mounting hole 1601. It may be understood that in other embodiments, the vent channel 164 may alternatively extend obliquely in a linear shape.
In other words, the extending direction of the vent channel 164 is not parallel to the axial direction of the vent tube 12. In some other embodiments, the vent channel 164 may alternatively be a non-linear channel, and/or, the quantity of the vent channel 164 may alternatively be one, two or more.

[0074] The cross-sectional dimension of the vent channel 164 (the dimension such as the width, depth, cross-sectional area, and the like of the vent channel 164) are set reasonably, so that liquid leakage is prevented because the liquid medium is difficult to pass the vent channel 164 due to a large resistance in the vent channel 164. In addition, the resistance for gas in the vent channel 164 is small so that the gas may be ventilated through the vent channel 164, thereby ensuring that the vent channel 164 has a good function of guiding gas and preventing liquid leakage. When a user inhales, release space filled with no liquid medium is produced in the liquid storage cavity 110 due to consumption of the liquid medium, and the outside air enters the liquid storage cavity 110 through the vent channel 164 to fill in the release space, to Date Recue/Date Received 2023-07-13 prevent inadequate liquid supply of the liquid medium in the liquid storage cavity 110 due to air pressure in the liquid storage cavity 110 being lower than external air pressure, and prevent dry heating of the vaporization core 130 due to a consumption rate of the liquid medium being greater than a supply rate.

[0075] FIG. 6 shows a base 16 in an alternative solution of the present disclosure, which is different from the foregoing first embodiment in that, in this embodiment, a vent channel 164 is in a helical shape.

There is one vent channel 164 that is roughly Z-shaped, and may include two longitudinal channels 1643 and 1645 extending longitudinally and spaced apart from each other, and a communication channel 1644 connecting the two longitudinal channels 1643 and 1645. The lower end of the longitudinal channel 1643 is in communication with a vent gap 144, and may extend a certain distance upwards from the outer wall surface of the lower end of the vent tube 12. The lower end of the longitudinal channel 1645 is in communication with the communication channel 1644, and the upper end is in communication with a liquid storage cavity 110.

[0078] It may be understood that in other embodiments, the quantity of the vent channel 164 may alternatively be one, two or more, and/or the vent channel 164 may alternatively be in a linear shape or a non-linear shape. The linear shape may include various shapes such as a zigzag shape, a curved shape (for example, an S shape or an arc shape), and a helical shape.

[0079] FIGS. 8 to FIG. 9 show a vaporizer 100 in a second embodiment of the present disclosure, which is different from the foregoing first embodiment in that, in this embodiment, Date Recue/Date Received 2023-07-13 a vent channel 164 is formed between the outer wall surface of a base 16 and the inner wall surface of a shell 11.

[0080] Specifically, in this embodiment, the vent channel 164 is formed by inward recession of the outer wall surface of the base 16. The vent channel 164 may be in a linear shape extending longitudinally, and may extend longitudinally from the upper end surface of an inserting part 162 to the lower end surface of a base part 161. The upper end of the vent channel 164 is in direct communication with a liquid storage cavity 110, and the lower end is in direct communication with outside air.

[0081] It may be understood that in other embodiments, the vent channel 164 may alternatively be formed by recession of the inner wall surface of the shell 11, and/or the quantity of the vent channel 164 may alternatively be one, two or more, and/or the vent channel 164 may alternatively be in various shapes such as a linear shape, a zigzag shape, a curved shape (for example, an S shape, an arc shape, or a helical shape), or the like.

[0082] In addition, a vaporization assembly 13 in this embodiment further includes a liquid guide cotton 137 fitted outside a liquid absorbing element 131 and in contact with the liquid absorbing element 131. A liquid medium in the liquid storage cavity 110 is absorbed by the liquid guide cotton 137 and distributed in the liquid guide cotton 137, and then delivered to the liquid absorbing element 131, thereby achieving a faster liquid guiding rate and more uniform liquid guiding.

Both the inner diameter and the outer diameter of the first tube section 121 are smaller than the inner diameter and the outer diameter of the second tube section 122, respectively. The vaporization assembly 13 is accommodated in the second tube section 122. The inner diameter of the second tube section 122 may be slightly smaller than the outer diameter of the liquid guide cotton 137, to enable the second tube section 122 to tightly clamp the liquid guide cotton 137. In this way, the vaporization assembly 13 can be fixed, and liquid leakage can be reduced through sealing. It may be understood that in other embodiments, the inner diameter of the second tube section 122 may alternatively be equal to or larger than the outer diameter of the liquid guide cotton 137.
