In some embodiments, the bottom base 11 may be in a shape of a cylinder and conductive. In some embodiments, the vent tube 12 may also be conductive, is longitudinally embedded in an upper portion of the bottom base 11, and is electrically connected to the bottom base 11. The vent tube 12 defines a columnar vaporization cavity 120. In some embodiments, the housing 13 may be in a shape of a cylinder, is longitudinally sleeved on the upper portion of the bottom base 11, and surrounds the vent tube 12. An annular liquid storage cavity 130 is defined between an inner wall surface of the housing 13 and an outer wall surface of the vent tube 12. A liquid inlet hole 122 communicating the liquid storage cavity 130 with the vaporization cavity 120 may be further formed on the vent tube 12. In some embodiments, the vaporization assembly 14 may be in a shape of a cylinder and is longitudinally arranged in the vaporization cavity 120. A middle portion of the vaporization assembly 14 may form a longitudinally run-through airflow channel 140. The electrode column 15 longitudinally runs through a lower portion of the bottom base 11 and is electrically insulated from the bottom base 11. Specifically, the lower portion of the bottom base 11 is longitudinally provided with an insulating sealing ring 16, and the electrode column 15 further runs through the insulating sealing ring 16, to implement insulating and sealing connection to the bottom base 11. One end of the first electrode claw 17 is fixed to an inner wall of the vent tube 12 and is electrically connected to the vent tube 12, and the other end is in elastic contact with an upper end of the vaporization assembly 14, so as to electrically connect the upper end of the vaporization assembly 14 to the vent tube 12. One end of the second electrode claw 18 is fixed to the electrode column 15 and is electrically connected to the electrode column 15, and the other end is in elastic contact with a lower end of the vaporization assembly 14, so as to electrically connect the lower end of the vaporization assembly 14 to the electrode column 15.
In some embodiments, the electrode column 15 is configured to be electrically connected to a positive electrode of the battery device 2, and the bottom base 11 is configured to be electrically connected to a negative electrode of the battery device 2, to form an electrical loop. Therefore, after flowing out of the positive electrode of the battery device 2, a current can flow through the electrode column 15 and the second electrode claw 18 sequentially and reach the lower end of the vaporization assembly 14; and after running through the vaporization assembly 14 and causing the vaporization assembly 14 to generate heat, the current reaches the upper end of the vaporization assembly 14, and then flows back to the negative electrode of the battery device 2 after flowing through the first electrode claw 17, the vent tube 12, and the bottom base 11 sequentially. It may be understood that, in some embodiments, the electrode column 15 and the bottom base 11 may alternatively be electrically connected to the negative electrode and the positive electrode of the battery device 2 respectively. In this case, a flowing direction of the current is opposite to the foregoing flowing direction.

In some embodiments, the vent tube 12 may be integrally formed by using a metal material and may include a first tube section 121, a second tube section 123 axially connected to an upper end of the first tube section 121, and a third tube section 125 axially connected to a lower end of the first tube section 121, where inner diameters and outer diameters of the third tube section 125, the first tube section 121, and the second tube section 123 are sequentially decreased. The first tube section 121 defines the vaporization cavity 120, and there may be a plurality of liquid inlet holes 122 uniformly formed on a circumferential direction of a side wall of the first tube section 121. A block ring 1231 extending toward a central axis may be arranged at a position close to the first tube section 121 on an inner wall surface of the second tube section 123, which is configured to provide axial resistance force for the first electrode claw 17. An end surface of the block ring 1231 close to the first electrode claw 17 may be a flat surface perpendicular to the central axis of the second tube section 123, and an end surface away from the first electrode claw 17 may be a conical surface in a shape of a horn. An outer diameter of the third tube section 125 matches an inner diameter of the first mounting tube 112, so that the third tube section 125 is longitudinally embedded in the first mounting tube 112 and tightly fits the first mounting tube 112. The height of the third tube section 125 is equal to the height of the first mounting tube 112. In some embodiments, to facilitate to embed the third tube section 125 in the first mounting tube 112, a guide portion 1251 is further formed on an outer wall surface of the third tube section 125 close to a lower end thereof through inward retraction, and an outer diameter of the guide portion 125 is less than that of the first mounting tube 112.
In some embodiments, the housing 13 may be made of a transparent material, and an inner diameter thereof matches the outer diameter of the first mounting tube 112, so that the housing 13 can be axially sleeved on the first mounting tube 112 through a lower end and tightly fits the first mounting tube 112. An upper end surface of the housing 13 may be slightly lower than an upper end surface of the second tube section 123, to better match the suction nozzle component 20. The liquid storage cavity 130 is defined between the inner wall surface of the housing 13 and the inner wall surfaces of the first tube section 121 and the second tube section 123, and an annular liquid injection opening 132 is formed between an upper end of the housing 13 and an upper end of the second tube section 123.
In some embodiments, the vaporization assembly 14 may include a longitudinally arranged cylindrical vaporization core 141, a first sealing ring 142 sleeved on an upper end of the vaporization core 141, and a second sealing ring 143 sleeved on a lower end of the vaporization core 141.
The first sealing ring 142 may include an L-shaped cross section configured to seal a gap between the upper end of the vaporization core 141 and the upper end of the first tube section 121. In some embodiments, the first sealing ring 142 may include a cylindrical first sealing portion 1421 and an annular second sealing portion 1423 connected to an upper end edge of the first sealing portion 1421, where the first sealing portion 1421 is sleeved on an outer wall surface of the upper end of the vaporization core 141, and the second sealing portion 1423 covers an upper end surface of the vaporization core 141. An inner diameter of the second sealing portion 1423 is preferentially greater than a pore size of the vaporization core 141, so that the first electrode claw 17 may not be blocked by the second sealing portion 1423 when matching the vaporization core 141.
The second sealing ring 143 may also include an L-shaped cross section configured to seal a gap between the lower end of the vaporization core 141 and the third tube section 125. In some embodiments, the second sealing ring 143 may include a cylindrical third sealing portion 1431 and an annular fourth sealing portion 1433 connected to a lower end edge of the third sealing portion 1431, where the third sealing portion 1431 is sleeved on an outer wall surface of the lower end of the vaporization core 141, and the fourth sealing portion 1433 covers a lower end surface of the vaporization core 141. A middle portion of the outer wall surface of the vaporization core 141 may directly face the liquid inlet hole 122. A middle portion of the vaporization core 141 forms a longitudinally run-through central through hole 1410. An inner diameter of the fourth sealing portion 1433 is preferentially greater than the pore size of the vaporization core 141, so that the second electrode claw 18 may not be blocked by the fourth sealing portion 1433 when matching the vaporization core 141.
In some embodiments, a first vent groove 1420 in a shape of a labyrinth is formed on an inner wall surface of the first sealing ring 142, and the first vent groove 1420 runs through inner wall surfaces of the first sealing portion 1421 and the second sealing portion 1423. A size of the first vent groove 1420 may be designed to be small enough to include capillary force in a use state, so as to communicate the liquid storage cavity 130 with an airflow channel in the vent tube 12 when the liquid storage cavity 130 is under a relatively great negative pressure, thereby achieving vapor-liquid equilibrium and preventing dry heating. In some embodiments, a second vent groove 1430 in a shape of a labyrinth may also be provided on an inner wall surface of the second sealing ring 143, and the second vent groove 1430 runs through inner wall surfaces of the third sealing portion 1431 and the fourth sealing portion 1433 and has a same function as the first vent groove 1420. In some embodiments, the first sealing ring 142 and the second sealing ring 143 have a same structure and may be compatible, thereby facilitating automated mounting and reducing mold making costs for a sealing ring.
It may be understood that, a vent structure may be arranged on any one of the first sealing ring 142 or the second sealing ring 143, which have advantages and disadvantages respectively. When the vent structure is only arranged on the first sealing ring 142, namely, the first vent groove 1420 of the first sealing ring 142, if liquid leakage occurs, some leaked liquid may flow downward from the upper end of the vaporization core 141 and is vaporized again after being absorbed by the vaporization core 141. When the vent structure is only arranged on the second sealing ring 143, although the possible leaked liquid easily leaks into the bottom base 11, an airflow direction in the airflow channel is flowing upward from the bottom, so that air supplement through the second sealing ring 143 is smoother. In some embodiments, the thickness of sealing silicone, namely, a distance between a surface in contact with the vaporization core 141 of the second sealing ring 143 and a surface in contact with the vent tube 12, at a lower end of the second sealing ring 143 is relatively large, so that the second sealing ring can better seal the lower end of the vaporization core 141 through interference fitting, thereby preventing liquid leakage. When comparison is performed, the thickness of the sealing silicon of the second sealing ring is compared with the thickness of a corresponding part of the first sealing ring 142.

In some embodiments, the heating element 1412 may be made of a material such as a nickel-chromium alloy, an iron-chromium-aluminum alloy, or a silver-palladium alloy, and is first printed or coated on an inner surface of a green body of the porous body 1411 and then formed on the inner wall surface of the porous body 1411 in a sintering manner. The heating element may include two long flat and clip-shaped heating circuits B arranged in parallel in an axial direction of the porous body 1411 and a connection circuit C connecting the two heating circuits in series, where a length direction of each of the two heating circuits B extending in a circumferential direction of the inner wall surface of the porous body 1411, so that the entire heating element is C-shaped. The heating element 1412 may further include an upper end circuit D and a lower end circuit A connected to an upper end and a lower end respectively, which are electrically connected to the first electrode 1413 and the second electrode 1414 respectively.
The first electrode 1413 and/or the second electrode 1414 may be made of a material such as silver or copper, and specifically, may be formed on the inner wall surface of the cylindrical porous body 1411 by coating/printing and sintering silver slurry or copper slurry. In addition, the first electrode and/or the second electrode are/is at least partially connected to the heating element 1412. In some embodiments, the first electrode 1413 and/or the second electrode 1414 may be C-shaped. Generally, slurry of the heating element 1412 is first printed on the green body of the porous body 1411, and slurry of the electrode is then printed or coated, and then the slurry is sintered together. In some embodiments, the width of a notch of the first electrode 1413 may be less than the width of a conductive portion 173, so that the first electrode claw 17 is in electrical contact with all conductive portions 173; and the width of a notch of the second electrode 1414 may be less than the width of a conductive portion 183, so that the second electrode claw 18 is in electrical contact with all conductive portions 183. It may be understood that, in some embodiments, the heating element 1412 may also be made of a metal heating sheet, and the porous body 1411 is also not limited to a porous ceramic material and may be made of any other suitable porous body material. It may be understood that, the first electrode 1413 and/or the second electrode 1414 are/is not limited to being distributed on an end portion of the inner wall surface of the porous body 1411 in a shape of C, and may also distributed on an entire circumferential direction of the end portion of the inner wall surface of the porous body 1411, namely, may be annular.
Arrangement of the first electrode 1413 and/or the second electrode 1414 does not require opening holes and introducing leads in the porous body 1411, so that an internal structure of the porous body 1411 is more complete, controllable, and reliable, and the product consistency is therefore well ensured. In addition, use of leads may be avoided, thereby reducing the manufacturing difficulty and production costs, which is more apparent for the small-size porous body 1411.
In some embodiments, by arranging the first electrode 1413 and the second electrode 1414 at two ends of the inner wall surface of the small-size porous body 1411 respectively may also have various benefits. An area of an inner wall of the small-size porous body 1411 is quite small, if two electrodes are arranged at one end, areas of the two electrodes are excessive small and are not conducive to establish stable electrical connection with an electrode connector, and a problem of short circuit may easily occur. By arranging the first electrode 1413 and the second electrode 1414 at two ends, deployment of the first electrode 1413 and the second electrode 1414 may be facilitated, and areas of the first electrode 1413 and the second electrode 1414 may be greater, thereby facilitating to establish stable electrical connection with the electrode connector.

In some embodiments, the first electrode claw 17 may be made of a material such as phosphor copper or 316 stainless steel, and a gold plated coating may be arranged on a surface of the first electrode claw. Preferably, the first electrode claw 17 is made of a phosphor copper material, and an impedance of the phosphor copper material is relatively small. The first electrode claw 17 may include a mounting portion 171 embedded in the inner wall surface of the second tube section 123, three extension portions 172 connected to the mounting portion 171, and three conductive portions 173 connected to the three extension portions 172 respectively. Each extension portion 172 and a corresponding conductive portion 173 form an elastic conductive arm of the first electrode claw 17. It may be understood that, a quantity of elastic conductive arms of the first electrode claw 17 is not limited to three and may be one or more than one, and when the first electrode claw includes a plurality of elastic conductive arms, electrical connection may be more reliable and assembly may be more convenient.
In some embodiments, the mounting portion 171 may be in a shape of a cylinder and includes a longitudinal fracture 1710 running through two side edges, where existence of the fracture 1710 causes deformation during mounting, thereby ensuring that the mounting portion 171 is better fixed to the inner wall surface of the second tube section 123. Specifically, a horn-shaped guide surface 1210 is arranged at a junction of the second tube section 123 and the first tube section 121. In a process that the first electrode claw 17 is axially inserted into the second tube section 123, the guide surface 1210 applies a radially inward component force to the mounting portion 171 of the first electrode claw 17, so that the fracture 1710 of the mounting portion 171 is closed, an outer diameter is reduced, and the first electrode claw can be inserted into the second tube section 123. After the first electrode claw is mounted in place, the mounting portion 171 provides a reaction force to the inner wall surface of the second tube section 123, so that the mounting portion can be firmly fixed to the second tube section 123. It may be understood that, in some embodiments, the mounting portion 171 may also be integrated together with the second tube section 123. In some embodiments, the mounting portion 171 may also be axially embedded in an upper end of the central through hole 1410 of the vaporization core 141 and elastically abuts against and fixed to the first electrode 1413, so that the elastic conductive arm extends out to be in elastic contact with the vent tube 12.
In some embodiments, the extension portion 172 may be in a shape of a bar and includes good elasticity, which first bends and extends by a certain distance from the mounting portion 171 toward a central axis of the mounting portion 171 and then extends in a direction parallel to the central axis of the mounting portion 171 and away from the mounting portion 171, to provide space for bending of the conductive portion 173 in a direction away from the central axis of the mounting portion 171 and provide a good elastic characteristic. Preferably, there are two or more than two extension portions 172, to ensure more reliable electrical connection; and when there are a plurality of extension portions 172, a best situation is that the extension portions are uniformly distributed at a lower side edge of the mounting portion 171 and extend downward. Specifically, the extension portion 172 first obliquely extends by a certain distance from the mounting portion 171 toward the central axis of the mounting portion 171, and then extends out in a direction parallel to the central axis and away from the mounting portion 171. One conductive portion 173 is arranged at a tail end of each extension portion 172, and is configured to be in elastic contact with the first electrode 1413 of the vaporization core 141. In some embodiments, the conductive portion 173 may be in a shape of a spoon. Specifically, the conductive portion 173 first obliquely extends toward a direction away from the central axis of the mounting portion 171, and then bends and obliquely extends toward a direction of the central axis. An inclined surface of the spoon-shaped structure leans inward and plays a role of guiding, and a bottom portion of the spoon-shaped structure is in arc transition, so that the spoon-shaped structure can be in better contact with the first electrode 1413 of the vaporization core 141 and may not scratch the first electrode 1413 during assembly. A vertical distance between a bottom portion of the conductive portion 173 and the central axis is slightly greater than a radius of a position of the central through hole 1410 of the vaporization core 141 at the first electrode 1413. Therefore, when the conductive portion 173 is axially inserted into the central through hole 1410, because the conductive portion 173 includes an inclined surface leaning inward, a reaction force applied by the vaporization core 141 to the conductive portion 173 includes a component force toward the direction of the central axis, so that the extension portion 171 is elastically deformed toward the direction of the central axis, and the conductive portion 173 can be inserted in this case. After the conductive portion 173 is inserted into the central through hole 1410, the elasticity of the extension portion 171 maintains close contact between the conductive portion 173 and the first electrode 1413.
In some embodiments, the second electrode claw 18 may be made of a material such as phosphor copper or 316 stainless steel, and a gold plated coating may be arranged on a surface of the second electrode claw. Preferably, the second electrode claw 18 is made of a phosphor copper material, and an impedance of the phosphor copper material is relatively small. The second electrode claw 18 may include a mounting portion 181 sleeved on an upper portion of the electrode column 15, an extension portion 182 connected to the mounting portion 181, and a conductive portion 183 connected to the extension portion 182. In some embodiments, the mounting portion 181 may be in a shape of a cylinder and includes a longitudinal fracture 1810 running through two side edges, where existence of the fracture 1810 causes deformation during mounting, thereby ensuring that the mounting portion 181 is better fixed to the upper portion of the electrode column 15. It may be understood that, in some embodiments, the mounting portion 181 may also be integrated with the electrode column 15. In some embodiments, the extension portion 182 may be in a shape of a bar and includes good elasticity. Preferably, there are two or more than two extension portions 182, to ensure more reliable electrical connection; and when there are a plurality of extension portions 181, a best situation is that the extension portions are uniformly distributed at a lower side edge of the mounting portion 181 and extend downward. One conductive portion 183 is arranged at a tail end of each extension portion 182, and is configured to be in elastic contact with the second electrode 1414 of the vaporization core 141. In some embodiments, the conductive portion 183 may be in shape of a spoon. An inclined surface of the spoon-shaped structure leans inward and plays a role of guiding, and a bottom portion of the spoon-shaped structure is in arc transition, so that the spoon-shaped structure can be in better contact with the second electrode 1414 of the vaporization core 141 and may not scratch the second electrode 1414 during assembly. In some embodiments, the second electrode claw 18 and the first electrode claw 17 may have a same structure and may be compatible. In this way, the assembly difficulty and costs may be reduced.
During assembly of the vaporization main body 10, the following steps may be used:
In the foregoing assembly steps of the vaporization main body 10, the first electrode claw 17 and the second electrode claw 18 implement quick electrical contact and conduction between components, which is more convenient and quick in operations when compared with an implementation of lead welding in the related art, so that automated assembly of products can be implemented more easily. It may be understood that, the serial numbers before the steps are only provided for ease of statement, and do not represent a sequence of the steps. For example, during specific assembly, the vent tube combination body may be first constructed, and the bottom base combination body is then constructed.

In this case, the liquid aerosol-generation substrate reaches a periphery of the vaporization core 141 through the liquid inlet hole 122, and the porous body 1411 of the vaporization core 141 absorbs the liquid aerosol-generation substrate through capillary force to the inner surface so as to be in contact with the heating element 1412. During use, the vaporization assembly 1 is mounted onto the battery device 2. When a user inhales through the suction nozzle portion 22, as shown by arrows X in
In some embodiments, the electrode column 15a is configured to be electrically connected to a positive electrode of a battery device 2a, and the bottom base 11a is configured to be electrically connected to a negative electrode of the battery device 2a, to form an electrical loop. Therefore, after flowing out of the positive electrode of the battery device 2a, a current can flow through the electrode column 15a and the second electrode claw 18a sequentially and reach the lower end of the vaporization assembly 14a; and after running through the vaporization assembly 14a and causing the vaporization assembly 14a to generate heat, the current reaches the upper end of the vaporization assembly 14a, and then flows back to the negative electrode of the battery device 2a after flowing through the first electrode claw 17a, the vent tube 12a, and the bottom base 11a sequentially. It may be understood that, in some embodiments, the electrode column 15a and the bottom base 11a may alternatively be electrically connected to the negative electrode and the positive electrode of the battery device 2a respectively. In this case, a flowing direction of the current is opposite to the foregoing flowing direction.
In some embodiments, the bottom base 11a may be integrally formed by using a metal material and may include a circular base 111a and a second mounting tube 113a longitudinally arranged on a bottom surface of the base 111a. A middle portion of the base 111a is provided with a longitudinally run-through through hole 1110a, and the through hole 1110a communicates a first tube section 121a of the vent tube 12a with the second mounting tube 113a. A mounting ring 1132a matching the insulating sealing ring 16a is formed on an inner wall surface of the second mounting tube 113a. An air inlet hole 1130a is further formed on a side wall of the second mounting tube 113a.
In some embodiments, the vent tube 12a may include a first tube section 121a integrally formed with the bottom base 11a and a second tube section 123a axially embedded in an upper end of the first tube section 121a and electrically connected to the first tube section 121a.

Based on this, when the first electrode column 15c and the second electrode column 16c are respectively conducted with a positive electrode and a negative electrode of a battery device, a current flowing out of the positive electrode of the battery device flows back to the negative electrode of the battery device after flowing through the first electrode column 15c, the first electrode 1413c, the first heating element 1412c, the electrical connection portion 1416c, the second heating element 1415c, the second electrode 1414c, and the second electrode column 16c sequentially, to implement a process that the first heating element 1412c and the second heating element 1415c generate heat. When compared with a conduction process with the assistance of components such as a bottom base and a vent tube in the related art, in an electrical loop of this heating process, selection of materials of the bottom base and the vent tube is more flexible and the components may be made of non-metal materials, so that costs of the entire vaporizer 1c may be significantly reduced. In addition, automated production of the vaporizer 1c becomes more convenient.
The vaporization assembly 14d may include a longitudinally arranged cylindrical vaporization core 141d, a first sealing ring 142d sleeved on an upper end of the vaporization core 141d, and a second sealing ring 143d sleeved on a lower end of the vaporization core 141d. A structure of the vaporization core 141d is the same as that of the vaporization core 141b of the vaporization assembly 14b and may include a cylindrical porous body 1411d, a heating element 1412d arranged on an inner wall surface of the porous body 1411d, a first electrode 1413d arranged on an upper end surface of the porous body 1411d and electrically connected to an upper end of the heating element 1412d, and a second electrode 1414d arranged on a lower end surface of the porous body 1411d and electrically connected to a lower end of the heating element 1412d. Main differences between the two structures lie in that: (1) The first sealing ring 142d is conductive, namely, has both sealing and conductive functions, and may be made of conductive silicone. (2) The second sealing ring 143d is a composite sealing ring, where an inner ring part is conductive to be electrically connected to the electrode column 15d; and an outer ring part is not conductive to electrically insulate the conductive inner ring part from the conductive bottom base 11d.
Based on the structure differences, in the vaporization main body 10d, the first electrode 1413d is electrically connected to the vent tube 12d through the first sealing ring 142d, and the second electrode 1414d is electrically connected to the electrode column 15d through the conductive inner ring part of the second sealing ring 143d. Compared with the vaporization main body 10b, no electrode claw extends into the airflow channel, so that interference to airflows in the airflow channel during a flowing process is reduced, and flowing of the airflows becomes smoother. In addition, after the first electrode claw 17b and the second electrode claw 18b are omitted, manufacturing costs can be reduced, assembly steps can be reduced, and the product stability can be improved.
While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive. It will be understood that changes and modifications may be made by those of ordinary skill within the scope of the following claims. In particular, the present invention covers further embodiments with any combination of features from different embodiments described above and below. Additionally, statements made herein characterizing the invention refer to an embodiment of the invention and not necessarily all embodiments.
The terms used in the claims should be construed to have the broadest reasonable interpretation consistent with the foregoing description. For example, the use of the article “a” or “the” in introducing an element should not be interpreted as being exclusive of a plurality of elements. Likewise, the recitation of “or” should be interpreted as being inclusive, such that the recitation of “A or B” is not exclusive of “A and B,” unless it is clear from the context or the foregoing description that only one of A and B is intended. Further, the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise. Moreover, the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
