As shown in
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 on the blocking part 211.
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.
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 another embodiment, the mouthpiece body 20 and the liquid storage and vaporization body 10 may alternatively be connected together in a non-detachable manner.
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 a base 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.
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 body 131 and a heating element 132 in contact with the liquid absorbing body 131. The liquid absorbing body 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 body 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 body 131. The liquid absorbing body 131 may be cylindrical, and is internally provided with a vaporization cavity 1310 running through the liquid absorbing body 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 body 131 may alternatively be made of other porous materials, not limited to a porous ceramic material.
The heating element 132 may be a heating film, and may be formed on a blank of the liquid absorbing body 131 by silk screen printing, printing, spraying or the like, then sintered together with the liquid absorbing body 131 and formed. Alternatively, the heating element 132 may be an independently formed metal heating sheet or metal heating wire. The heating element 132 includes at least one heating track 1321 and two end surface electrodes 1322 and 1323 connected to two poles of the 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 body 131 to generate heat after energized, to heat and vaporize the liquid medium adsorbed by the liquid absorbing body 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 absorbing body 131 for external connection of an external power supply. Further, in other embodiments, the heating element 132 may also include 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 body 131. The upper and lower ends of the heating track 1321 are connected to the two end surface electrodes 1322 and 1323 through the two connection electrodes 1324 and 1325, respectively. 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 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 body 131. This is beneficial to uniformly heat the liquid medium adsorbed by the liquid absorbing body 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. The two connection electrodes 1324 and 1325 are cylindrical, and the two end surface electrodes 1322 and 1323 are thin annular discs. The upper end of the connection electrode 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 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.
In some embodiments, the vaporization core 130 may further include a liquid guide cotton 137 fitted outside the liquid absorbing body 131 and in contact with the liquid absorbing body 131. The liquid medium in the liquid storage cavity 110 is adsorbed by the liquid guide cotton 137 and distributed in the liquid guide cotton 137, and then delivered to the liquid absorbing body 131. In this way, the liquid guide is faster and more uniform.
The base 16 is disposed at the lower end of the shell 11 and blocks the lower end of the liquid storage cavity 110. In some embodiments, both the base 16 and the vent tube 12 are electrically conductive. The end surface electrode 1322 can be directly or indirectly electrically connected to the vent tube 12, to electrically connected to the base 16. The electrode column 14 is inserted into the base 16 in the longitudinal direction and is electrically insulated from the base 16. The end surface electrode 1323 is directly or indirectly electrically connected to the electrode column 14.
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 insertion 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 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. At least one air inlet hole 1630 may also be formed in the side wall that is at the upper part of the connecting part 163 and that is not provided with the threaded structure, to allow outside air to enter the vaporization cavity 1310. In this embodiment, there are a plurality of air inlet holes 1630, and the plurality of air inlet holes 1630 are evenly arranged at intervals in the circumferential direction of the connecting part 163.
The insertion 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 insertion 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. Specifically, in this embodiment, the insertion part 162 may include a body part 1621 and a sealing boss 1622 extending outward from the body part 1621. The outer wall surface of the body part 1621 may be in a clearance fit with the inner wall surface of the shell 11. The body part 1621 has a longer length in the axial direction, so that force required for mounting the base 16 into the shell 11 is reduced. The sealing boss 1622 is in an interference fit with the inner wall surface of the shell 11. The sealing effect is enhanced by the interference fit. The axial length of the sealing boss 1622 is short, so that force required for mounting the base 16 into the shell 11 is reduced while sealing performance is ensured. In addition, the sealing boss 1622 may be disposed on the top of the body part 1621 or close to the top of the body part 1621, so that less liquid medium penetrates between the outer wall surface of the insertion part 162 and the inner wall surface of the shell 11, thereby achieving a better liquid leakage prevention effect. A guide bevel 1623 may also be formed at the upper end of the sealing boss 1622. The outer diameter of the guide bevel 1623 gradually decreases from bottom to top, and the outer diameter of the upper end of the guide bevel 1623 is smaller than the inner diameter of the shell 11, so that the sealing boss 1622 can be easily guided into the shell 11. It may be understood that in other embodiments, the outer wall surface of the body part 1621 may alternatively be in a transition fit with the inner wall surface of the shell 11. In some other embodiments, the sealing boss 1622 may alternatively be located at the middle or lower part of the body part 1621.
Further, the insertion part 162 may further include a joint part 1624 connected to the lower end of the body part 1621. The outer wall surface of the joint part 1624 may be in an interference fit with the inner wall surface of the shell 11. This can further improve the liquid leakage prevention effect, and can make fixation of the insertion part 162 in the shell 11 more reliable. In addition, the insertion part 162 is located at the opening of the shell 11, and has little influence on the force required for mounting the base 16 into the shell 11. It may be understood that in other embodiments, the outer wall surface of the joint part 1624 and the inner wall surface of the shell 11 may alternatively be in a transition fit or a clearance fit.
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 insertion 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.
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.
The vent tube 12 may be integrally formed by a metal material, and may include a first tube section 121 and a second tube section 122 connected to the lower end of the first tube section 121. 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. The outer diameter of the first tube section 121 is small, 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 larger liquid storage space. The lower end of the second tube section 122 is inserted in the base 16, and the outer wall surface of the second tube section 122 is in electrical contact with the inner wall surface of the base 16. It may be understood 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.
The vaporization core 130 is accommodated in the second tube section 122, and at least one liquid inlet 1220 is formed in the side wall of the second tube section 122, to enable the liquid medium in the liquid storage cavity 110 to flow into the vaporization core 130 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 body 131. 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 core 130 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.
The upper end of the second tube section 122 has a conductive end surface 1221. The conductive end surface 1221 directly or indirectly abuts against and is electrically connected to the end surface electrode 1322. In this embodiment, the conductive end surface 1221 directly abuts against and is electrically connected to the end surface electrode 1322.
In some embodiments, the vaporization assembly 13 further includes a conductive connector 135. The electrode column 14 is electrically connected to the end surface electrode 1323 through the conductive connector 135. Further, 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. The conductive connector 135 may include a body part 1351 and at least one elastic arm 1352 connected to the body part 1351. The at least one elastic arm 1352 may be in elastic and electrical contact with the conductive end surface 1411 or the end surface electrode 1323. The conductive connector 135 may produce certain elastic deformation in the longitudinal direction, to cause the vaporization core 130 to produce certain elastic floating in the longitudinal direction. As a result, a reliable electrical connection is still formed between the conductive end surface 1411 and the end surface electrode 1323 in the case of low product uniformity. In addition, due to the elasticity of the conductive connector 135, the porous ceramic liquid absorbing body can be prevented from being damaged during installation.
Specifically, in this embodiment, the outer wall surface of the electrode column 14 protrudes outward to form a circular flange 1412. A conductive end surface 1411 is formed on the upper end surface of the flange 1412. The center part of the top surface of the electrode column 14 may extend downwards to form a center hole 140. The center hole 140 is located under the vaporization cavity 1310 and can receive and accommodate certain leaked liquid or condensate. The lower end of the center hole 140 has a bottom wall 143. The bottom wall 143 seals the lower end of the center hole 140, to prevent leakage of the leaked liquid or condensate in the center hole 140 to the outside. A circular vent gap 144 is formed between the outer wall surface of the electrode column 14 and the inner wall surface of the base 16. The air inlet hole 1630 is communicated with vaporization cavity 1310 through the vent gap 144. There is a spacing between the upper end surface of the electrode column 14 and the lower end surface of the vaporization core 130. The spacing can play a role of heat insulation and air circulation.
The spacing can prevent the vaporization core 130 from being in direct contact with the electrode column 14, and prevent heat of the vaporization core 130 from being directly transferred to the electrode column 14, thereby achieving heat insulation. In addition, the spacing also communicates the vent gap 144 with the vaporization cavity 1310.
As shown in
The body part 1351 is cylindrical and is fitted on the upper part of the electrode column 14. The lower end of the body part 1351 abuts against the conductive end surface 1411 and is in electrical contact with the conductive end surface 1411. The inner wall surface of the body part 1351 is in electrical contact with the outer wall surface of the electrode column 14. In this way, the fixation of the conductive connector 135 on the electrode column 14 is more reliable, and the electrical connection between the conductive connector 135 and the electrode column 14 is more reliable. A flare structure 1353 may also be provided at the bottom of the body part 1351. The diameter of the flare structure 1353 gradually decreases from bottom to top, to facilitate the fitting of the body part 1351 onto the electrode column 14. In addition, the outer surface of the upper end of the electrode column 14 may also be formed with a guide bevel, to facilitate the fitting of the body part 1351 onto the electrode column 14.
Preferably, there are a plurality of elastic arms 1352. The plurality of elastic arms 1352 are evenly arranged at intervals in the circumferential direction of the body part 1351. Each elastic arm 1352 includes a conducting part 1355 configured to elastically abut against and be electrically connected to the end surface electrode 1323 and a connecting arm 1356 connecting the conducting part 1355 and the body part 1351. In some embodiments, the quantity of the elastic arms 1352 may range from two to four. This can ensure the width of the elastic arms 1352 to enable the elastic arms 1352 to be in electrical contact with the end surface electrode 1323 more stably, and can meet requirements of a manufacturing process and facilitate manufacturing. Specifically, in this embodiment, the quantity of the elastic arms 1352 is two.
Further, in this embodiment, the connecting arm 1356 is sheet-shaped and has good elasticity, and may extend upward from the top surface of the body part 1351 and obliquely toward the center of the body part 1351. The conducting part 1355 may roughly have a spoon-shaped structure, and may be formed by the end of the connecting arm 1356 away from the body part 1351 bending toward the inside of the body part 1351, that is, the bowl of the spoon faces the inside of the body part 1351. The bevel of the spoon-shaped structure has a guiding effect, and the bottom of the spoon is an arc surface, to be in better contact with the end surface electrode 1323. It may be understood that in other embodiments, the connecting arm 1356 may alternatively be inclined away from the center of the body part 1351, and/or, the bowl of the scoop of the conducting part 1355 may alternatively face the outside of the body part 1351.
It may be understood that in other embodiments, the conductive end surface 1411 may also be formed on the upper end surface of the electrode column 14. In some other embodiments, the body part 1351 may abut against and be electrically connected to the end surface electrode 1323, and the elastic arm 1352 may elastically abut against and be electrically connected to the conductive end surface 1411.
As shown in
Further, at least one vent passage 152 for air circulation may also be formed on the insulating sleeve 15. 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.
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 1521 formed in the upper end surface of the insulating sleeve 15 and a vent groove 1522 communicated with the vent 1521 and formed in the longitudinal direction in 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. In some other embodiments, the vent groove 1522 may also extend in a non-linear shape, such as a spiral shape, an S shape, or a zigzag shape.
It may be understood that the foregoing technical features can be used in any combination without limitation.
