If the operating part is pulled further in a direction away from the liquid storage cavity until the second sealing part abuts against the sealing gasket, the first sealing part inserts into the operating part through hole to seal the operating part through hole. The operating part and the first sealing part are disconnected through the transverse notch.

[0074] Furthermore, when the seal is pulled, the seal deforms, forming a gap between the operating part and the wall of the perforation of the operating part. External gas enters the liquid storage chamber through the gap. A sealing strip is provided on the outer wall of the first sealing part in a radial direction.

[0150] Detailed Implementation

[0151] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0152] Please see Figure 1 , Figure 2 This invention provides an electronic cigarette comprising a cartridge 10 and a battery device 20 cooperating with the cartridge 10, wherein the cartridge 10 and the battery device 20 are detachably connected. The electronic cigarette also includes an atomizing device. In use, the battery device 20 supplies power, and the atomizing device, driven by the battery device 20, atomizes the aerosol stored within the cartridge 10 to form a matrix. The aerosol matrix forms smoke under atomization, which is then inhaled by the user. The atomizing device can be at least one of a microwave heating device, an infrared heating device, an electromagnetic induction heating device, an ultrasonic atomizing device, and a resistance heating device. The atomizing device can be mounted on the cartridge 10, on the battery device 20, or independently of both the cartridge 10 and the battery device 20. When the atomizing device is mounted on the battery device 20 or independently of the cartridge 10 and the battery device 20, the user does not need to replace the atomizing device when replacing the cartridge 10, thus reducing replacement costs. The aerosol forming matrix can be e-liquid, tobacco, or tobacco paste. The structure of the cartridge 10 varies depending on the type of aerosol forming matrix. For example, when the aerosol forming matrix is ​​tobacco, the cartridge 10 can be configured to resemble the structure of a regular cigarette. In this embodiment, we take e-liquid as an example as the aerosol forming matrix.

[0153] Please see Figure 4 , Figure 7 and Figure 8 The cartridge 10 includes a sealing element 14, a mouthpiece 13 with a smoke outlet 131, a cartridge shell 16, a sealing gasket 162, a liquid-absorbing element 17, a liquid-absorbing element support 18, and a base 15. The mouthpiece 13 is installed at the upper end of the cartridge shell 16, the sealing gasket 162 is disposed at the upper end of the cartridge shell 16 and located between the mouthpiece 13 and the cartridge shell 16, a portion of the sealing element 14 is inserted into the interior of the cartridge shell 16 via the mouthpiece 13 and the sealing gasket 162, and the other portion of the sealing element 14 is exposed to the exterior of the cartridge 10, the liquid-absorbing element 17 and the liquid-absorbing element support 18 are disposed in the lower end of the cartridge shell 16, and the base 15 is connected to the lower end of the cartridge shell 16. The base 15 is provided with an atomizing chamber 151, an air inlet 152 and a mating part 153. The air inlet 152 and the mating part 153 are located on opposite sides of the atomizing chamber 151. When the cartridge 10 is installed on the battery device 20, the mating part 153 and the battery device 20 form a specific mating structure to detect whether the cartridge 10 is installed on the battery device 20 and whether the cartridge 10 has been removed from the battery device 20.

[0154] The cartridge shell 16 is generally a hollow cylindrical structure with both ends open. The inner cavity of the cartridge shell 16 forms a liquid storage chamber 19 for storing e-liquid. The volume of the liquid storage chamber 19 is 0.5-3 ml. If the volume of the liquid storage chamber 19 is too small, the amount of e-liquid stored will not meet the user's vaping needs. If the volume of the liquid storage chamber 19 is too large, the amount of e-liquid stored will be too large, which may cause the user to not be able to use it up in one day. When the volume of the liquid storage chamber 19 is 0.5-3 ml, it can just meet the user's vaping needs. An airflow channel 165 is opened along the axial direction of the cartridge shell 16 in the wall on one side. Both the liquid storage chamber 19 and the airflow channel 165 are open at the upper and lower ends, and the liquid storage chamber 19 and the airflow channel 165 are isolated from each other. The lower opening of the airflow channel 165 is connected to the atomizing chamber 151 of the base 15, and the upper opening of the airflow channel 165 is connected to the smoke outlet 131 of the mouthpiece 13. The air inlet 152 on the base 15 is connected to the atomizing chamber 151. The upper opening of the liquid storage chamber 19 is sealed by a sealing gasket 162, which has a through hole 163 for the operation part of the sealing member 14. The lower opening of the liquid storage chamber 19 forms a liquid outlet 191, which connects the liquid storage chamber 19 and the liquid suction member 17. The lower end of the cartridge shell 16 extends downward along the axial direction of the cartridge shell 16 to form a receiving part (not shown in the figure). The liquid suction member 17 is fixedly installed outside the liquid outlet 191 and inside the receiving part by a liquid suction member bracket 18. The liquid suction member 17 is connected to the atomizing chamber 151 on the base 15. The lower end of the seal 14 passes through the outside of the cartridge 10, sequentially through the mouthpiece 13 and the operating perforation 163 of the sealing gasket 162, and is inserted into the liquid storage chamber 19, sealing the outlet 191. This seals the liquid storage chamber 19, preventing leakage of e-liquid before use, facilitating storage and transportation, and preventing the e-liquid in the liquid storage chamber 19 from deteriorating due to contact with outside air. When the user needs to use the electronic cigarette, the seal 14 can be removed from the outlet 191, opening the outlet 191. The e-liquid in the liquid storage chamber 19 can then come into contact with the suction device 17 through the outlet 191 and be absorbed by the suction device 17.

[0155] In one specific embodiment, the liquid suction bracket 18 is generally a hollow box-shaped structure with through holes at both the upper and lower ends, and the liquid suction component 17 is installed inside the cavity of the liquid suction bracket 18. Multiple bendable portions 181 are provided on the sidewalls of the liquid suction bracket 18 around the upper through hole. During installation, the liquid suction component 17 is placed in the cavity of the liquid suction bracket 18, so that the lower surface of the liquid suction component 17 is in contact with the bottom wall of the liquid suction bracket 18. Then, the bends 181 are bent at a certain angle, and downward pressure is applied to make the bends 181 fit against the upper surface of the liquid suction component 17, thereby fixing the liquid suction component 17 onto the liquid suction bracket 18. The operation is simple and convenient, and the installation of the liquid suction component 17 can be automated. In this embodiment, the absorbent element 17 is cotton. It can be understood that in other embodiments not shown, the absorbent element 17 may also be a fiber rope, porous ceramic or porous graphite or other elements with absorbent capacity, and there is no limitation here.

[0156] Please combine further Figure 4 , Figure 7 and Figure 8In this embodiment, the sealing member 14 includes an operating part 141 and a sealing part (not shown in the figure). One end of the operating part 141 extends to the outside of the cartridge 10 and can be operated by the user. The other end of the operating part 141 passes through the operating part through hole 163 and extends into the liquid storage chamber 19. The part of the operating part 141 located in the operating part through hole 163 seals the operating part through hole 163 to prevent liquid leakage. The sealing part includes a first sealing part 142 and a second sealing part 143 connected to each other. One end of the first sealing part 142 is connected to the end of the operating part 141 located in the liquid storage chamber 19, and the other end of the first sealing part 142 is connected to the second sealing part 143. The connection between the first sealing part 142 and the operating part 141 has a transverse notch 145. The second sealing part 143 is used to seal the liquid outlet 191. When the operating part 141 moves outward along the operating part perforation 163 under the action of external force, it drives the first sealing part 142 to move upward along the axis of the cigarette cartridge 10. The first sealing part 142 then drives the second sealing part 143 to open the liquid outlet 191. The radial width of the second sealing part 143 is greater than the diameter of the operating part through hole 163. When the operating part 141 is pulled upward along the axial direction of the cigarette cartridge 10 until the second sealing part 143 abuts against the lower end face of the sealing gasket 162, the sealing member 14 can no longer move upward. The first sealing part 142 is inserted into the operating part through hole 163 to seal the operating part through hole 163. Since the connection between the first sealing part 142 and the operating part 141 has a transverse notch 145, the operating part 141 and the first sealing part 142 can be separated under the action of external force, so that the operating part 141 can be removed after being separated from the first sealing part 142. The first sealing part 142 seals the operating part through hole 163 without damaging the sealing of the upper end of the liquid storage chamber 19. In addition, the through hole on the mouthpiece 13 for inserting the sealing member 14 becomes the smoke outlet 131 after the operating part 141 is removed. In this embodiment, a sealing strip 1421 protrudes radially outward from the outer wall of the first sealing part 142. The sealing strip 1421 fits tightly against the wall of the through hole 163 of the operating part, improving the sealing performance of the liquid storage chamber 19. The travel distance of the sealing member 14 (the distance the second sealing part 143 travels from the liquid outlet 191 to the point where the second sealing part 143 abuts against the lower end face of the sealing gasket 162) is 5-50 mm. In one specific embodiment, the travel distance of the sealing member 14 is 10-15 mm. If the travel distance is too short, it indicates that the axial length of the liquid storage chamber 19 is too short, which may result in a small volume of the liquid storage chamber 19. If the travel distance is too long, it will cause inconvenience to the user.

[0157] Furthermore, during the pulling of the sealing element 14, the sealing element 14 deforms under the pulling force, forming a gap between the operating part 141 and the wall of the operating part perforation 163. External air can enter the liquid storage chamber 19 through this gap, thus facilitating the e-liquid in the liquid storage chamber 19 to flow out from the liquid outlet 191 and come into contact with the suction element 17, where it is then absorbed. Otherwise, a negative pressure would form in the liquid storage chamber 19, which would be detrimental to the flow of e-liquid. Simultaneously, the suction element 17 is located between the upper opening of the atomizing chamber 151 and the liquid outlet 191. Since the liquid suction component 17 is located directly below the liquid outlet 191, when the liquid outlet 191 is opened, the e-liquid in the storage chamber 191 can be absorbed by the liquid suction component 17 after flowing out of the liquid outlet 191, which shortens the flow distance of the e-liquid. In actual use, the size of the liquid outlet 191 can be set to be slightly larger, as long as the size of the liquid outlet 191 matches the size of the liquid suction component 17. Thus, the e-liquid can be quickly absorbed by the liquid suction component 17, shortening the waiting time for the liquid suction component 17 to absorb the e-liquid after the user removes the operation part 141, making it convenient for the user to use the electronic cigarette quickly.

[0158] In this embodiment, the atomizing device is mounted on the battery device 20. The atomizing device is a resistance heating device, specifically, the heating element 21. The size of the lower opening of the atomizing chamber 151 matches the size of the heating element 21. When the cartridge 10 is mounted on the battery device 20, the heating element 21, mounted on the battery device 20, extends into the atomizing chamber 151 from the lower opening and contacts or maintains a preset distance from the liquid-absorbing component 17. Under electric drive, the heating element 21 generates heat to heat the e-liquid on the liquid-absorbing component 17, and the heated e-liquid forms smoke. When the user uses the device, the smoke generated by the atomized e-liquid in the atomizing chamber 151 flows out through the airflow channel 165 and the smoke outlet 131. When the e-liquid in the storage chamber 19 is depleted, the user can replace the cartridge 10 with a new one. Since the heating element 21 is mounted on the battery device 20, the replacement of the cartridge 10 does not involve the heating element 21, reducing the replacement cost of the cartridge 10. Furthermore, the diameter of the lower opening of the airflow channel 165 is larger than the diameter of the upper opening of the airflow channel 165, resulting in lower suction pressure at the lower opening of the airflow channel 165 and preventing large particles of e-liquid from being drawn out. In addition, the lower wall of the airflow channel 165 is designed as an arc surface, making the connection smoother, reducing the obstruction encountered by the smoke, and making it less likely to generate condensate. Specifically, one side wall of the liquid storage chamber 19 and one side wall of the airflow channel 165 are the same wall (not shown in the figure). The lower end of the wall and the other walls of the liquid storage chamber 19 form the outlet 191, the upper end of the wall and the other walls of the airflow channel 165 form the upper opening of the airflow channel 165, and the lower end of the wall and the other walls of the airflow channel 165 form the lower opening of the airflow channel 165. The lower end of the wall is curved towards the liquid storage chamber 19, so that the diameter of the upper opening of the airflow channel 165 is smaller than the diameter of the lower opening of the airflow channel 165. At the same time, the diameter of the outlet 191 is relatively small. Specifically, the lower end of the storage cavity 19 contracts inward to prevent the liquid in the storage cavity 19 from flowing out of the outlet 191 too quickly.

[0159] Furthermore, the electronic cigarette of the present invention employs an isolation structure. Specifically, before using the electronic cigarette, the e-liquid in the storage chamber 19 is isolated from the suction member 17 through the isolation structure, keeping the e-liquid within the storage chamber 19. When needed, the storage chamber 19 is opened, allowing the e-liquid in the storage chamber 19 to flow onto the suction member 17 and be absorbed by the suction member 17. This facilitates the storage and transportation of the cartridge 10. Moreover, it effectively prevents the suction member 17 from absorbing some e-liquid before contacting the heating element 21, thus preventing the heating element 21 from squeezing the suction member 17 and squeezing out the absorbed e-liquid when the cartridge 10 is installed, thereby avoiding e-liquid leakage. Understandably, when the suction member 17 is made of a hard material such as porous ceramic, an isolation structure may not be provided between the storage chamber 19 and the suction member 17. The suction member 17 will not deform under the pressure of the heating element 21, therefore, the e-liquid on the suction member 17 will not be squeezed out. Understandably, in other embodiments not shown, in addition to using the seal 14 as an isolation structure, other isolation structures may be used, such as a puncturable sealing membrane or a movable sealing plate, by puncturing the sealing membrane or the movable sealing plate to open the liquid reservoir 19.

[0160] Please refer to it again. Figure 7 , Figure 8 The base 15 is located within the receiving section and is snapped into the cartridge shell 16. To ensure the airtightness of the base 15, a base seal 161 is also provided between the base 15 and the cartridge shell 16. The base seal 161 is sleeved on the outside of the upper end of the base 15. A mounting portion 166 is provided on the upper end surface of the base seal 161, corresponding to the upper opening of the atomizing chamber 151. The lower end of the mounting portion 166 is provided, and the liquid suction member 17 is mounted on the liquid suction member bracket 18. The liquid suction member 17 and the liquid suction member bracket 18 are received in the mounting portion 166 after passing through the lower opening of the mounting portion 166. The upper end of the mounting portion 166 has a liquid passage hole 167 communicating with the liquid suction member 17. When the liquid outlet 191 is opened, the liquid passage hole 167 is also communicating with the liquid outlet 191. In addition, the upper end face of the base seal 161 is recessed downward to form a recessed groove 1611 communicating with the liquid passage 167. The lower end face of the liquid storage chamber 19 extends downward to correspond to the liquid outlet 191 and forms an insertion part 160 that mates with the recessed groove 1611. The insertion part 160 is inserted into the recessed groove 1611, which can effectively prevent e-liquid leakage. At the same time, the wall of the liquid storage chamber 19 is inclined at a preset distance from the liquid outlet 191. The inclined wall can guide the flow of e-liquid, which is conducive to the smooth flow of e-liquid.

[0161] An air guide portion 168 protrudes upward from the upper end surface of the base seal 161. The air guide portion 168 is inserted into the airflow channel 165 through the lower end opening of the airflow channel 165, increasing the sealing performance of the airflow channel 165. A guide groove 157 is provided on the base 15 corresponding to the air guide portion 168. One end of the guide groove 157 passes through the upper end surface of the base 15 along the axial direction of the cartridge 10 and communicates with the air guide portion 168. The other end of the guide groove 157 passes through the cavity wall of the atomizing chamber 151 along the radial direction of the cartridge 10 and communicates with the atomizing chamber 151. The smoke in the atomizing chamber 151 flows out sequentially through the guide groove 157, the air guide portion 168, the airflow channel 165, and the smoke outlet 131. A connecting groove 155 is provided on the base 15 relative to the air guide groove 157. One end of the connecting groove 155 passes through the cavity wall of the atomizing chamber 151 along the radial direction of the cartridge 10 and is connected to the atomizing chamber 151. The other end of the connecting groove 155 passes through the lower end face of the base 15 along the axial direction of the cartridge 10 to form an air inlet 152. In this way, the air inlet 152 and the lower end opening of the atomizing chamber 151 are arranged parallel to each other along the axial direction of the cartridge 10. That is, the two are staggered in the axial direction of the cartridge 10, which can prevent the condensate formed by the smoke in the atomizing chamber 151 from entering the air inlet 152 and further entering the battery device 20 through the air inlet 152, affecting the use of the electronic components in the battery device 20. Additionally, a baffle 156 is provided within the connecting groove 155, with vent holes 1561 formed on the baffle 156. The vent holes 1561 connect to both the air inlet 152 and the connecting groove 155. The vent holes 1561 have a small diameter, making it difficult for condensate to pass through and enter the air inlet 152 due to surface tension. Vent holes 1561 can also be formed on the wall of the atomizing chamber 151. These vent holes 1561 connect the atomizing chamber 151 and the connecting groove 155, preventing condensate from entering the connecting groove 155.

[0162] To facilitate the injection of e-liquid into the storage chamber 19, a groove 169 is provided on each side of the upper end surface of the sealing gasket 162 opposite to the sealing element 14. A connecting port (not shown in the figure) is provided on each side of the sealing element 14 on the mouthpiece 13. During injection, one of the connecting ports serves as the injection port, and the other as the exhaust port. The injection needle passes through the injection port and the corresponding groove 169 sequentially before entering the storage chamber 19 to inject e-liquid. The exhaust needle passes through the exhaust port and the corresponding groove 169 sequentially before entering the storage chamber 19 to expel gas from the storage chamber 19 during injection. After injection, the injection and exhaust needles are removed, and the sealing gasket 162 forms a self-sealing seal at the puncture points of the injection and exhaust needles, preventing leakage. The grooves 169 reduce the thickness of the sealing gasket 162, thus facilitating the puncture by the injection and exhaust needles. Throughout the liquid injection process, the suction element 17 and the storage chamber 19 remain isolated from each other, effectively preventing leakage of the e-liquid through the suction element 17 and preventing air from disturbing the suction element 17 and causing it to shift position. When drawing through the mouthpiece 13, the two connecting ports are used as smoke outlets 131.

[0163] Additionally, please combine Figure 5 , Figure 6A liquid collecting element 164 is also provided between the sealing gasket 162 and the mouthpiece 13. The liquid collecting element 164 is used to absorb large particles of e-liquid or condensate. Specifically, the inner end face of the mouthpiece 13 is provided with a first connecting pipe 132, a second connecting pipe 133, and a third connecting pipe 134, all of which are through at both ends, protruding sequentially along the axial direction of the cartridge 10. The inner cavity of the first connecting pipe 132 forms one connecting port, and the inner cavity of the third connecting pipe 134 forms the other connecting port. The operating part 141 of the sealing element 14 passes through the inner cavity of the second connecting pipe 133. A plurality of reinforcing ribs 136 are also provided on the inner end face of the mouthpiece 13 along the axial direction of the cartridge 10. The liquid collecting element 164 is sandwiched between the reinforcing ribs 136 and at least one of the first connecting pipe 132, the second connecting pipe 133, and the third connecting pipe 134. In this embodiment, there are two liquid collecting elements 164, which are arranged opposite to each other. In one specific embodiment, the liquid collecting element 164 is made of cotton. The cotton is soft and can fully conform to the first connecting pipe 132, the second connecting pipe 133, the third connecting pipe 134, and the reinforcing rib 136. This effectively prevents condensate or large particles of e-liquid from entering the user's mouth through the liquid collecting element 164, thus improving the liquid absorption capacity of the liquid collecting element 164. It is understood that in other embodiments not shown, the liquid collecting element 164 can also be a fiber rope, porous ceramic, porous graphite, or other components with liquid absorption capacity. Furthermore, the sealing gasket 162 has a guide groove 1621 and an installation groove 1622 corresponding to the reinforcing rib 136. When installing the mouthpiece 13, the reinforcing rib 136 slides along the guide groove 1621, causing a portion of the reinforcing rib 136 to insert into the installation groove 1622, thereby establishing the connection between the mouthpiece 13 and the sealing gasket 162.

[0164] Please refer to it again. Figure 4 , Figure 7The mouthpiece 13 is fitted onto the upper exterior of the cartridge housing 16. Both the mouthpiece 13 and the cartridge housing 16 are flat structures, effectively preventing the cartridge 10 from rolling off a pressure-bearing surface (e.g., a tabletop). Additionally, a locking protrusion 1601 protrudes from the opposite sidewall of the cartridge housing 16, and a locking groove 1301 is formed on the sidewall of the mouthpiece 13 corresponding to the locking protrusion 1601. The locking protrusion 1601 and the locking groove 1301 engage, thus establishing the connection between the cartridge housing 16 and the mouthpiece 13 and preventing the mouthpiece 13 from being arbitrarily disassembled after installation. Simultaneously, the end of the mouthpiece 13 furthest from the cartridge housing 16 is the suction end, with the smoke outlet 131 located on it. The outer surface of the mouthpiece 13 tapers inward at a predetermined distance from the suction end and is curved, conforming to ergonomics and providing a superior suction experience. When the cartridge 10 is installed, the suction end is located outside the battery housing 24. The cartridge shell 16 is made of transparent or semi-transparent material. The part of the mouthpiece 13 corresponding to the liquid storage cavity 19 is provided with a notch 135, so that the cartridge shell 16 is partially exposed through the notch 135, thereby forming a window that can be observed to see the liquid storage cavity 19, making it convenient for users to observe the amount of e-liquid used or remaining.

[0165] The bottom of the cartridge 10 is covered with a dust cover (not shown) or the cartridge 10 is contained in a sealed bag (not shown) to prevent the liquid absorption part 17 from being contaminated before use and affecting the user's use.

[0166] Please see Figures 9 to 13The battery device 20 includes a heating element 21, a conductive post 231, and a battery device body. The battery device body includes a detection component 25, a battery casing 24, a battery bracket 23, a bracket seal 22, a battery 233, and a first control board 29. The heating element 21 can be a heating plate, a heating mesh, a heating wire, or a heating rod. When a heating plate or a heating mesh is used, the contact area between the heating element 21 and the liquid-absorbing component 17 is large and uniform, which can uniformly heat the e-liquid on the liquid-absorbing component 17 and prevent local overheating. The heating element 21 can be made of metal, ceramic, or metal-ceramic composite materials. In one specific embodiment, the heating element 21 can be a ceramic heating plate, in which tungsten paste is sintered in aluminum nitride ceramic. The two are densely bonded with a porosity of less than 1%, which allows the heating element 21 to heat up rapidly and the temperature distribution to be uniform. However, the type of heating element 21 is not limited to this. Aluminum nitride ceramic refers to ceramics whose composition includes aluminum nitride. At the same time, the composition of aluminum nitride ceramics can also include other substances, such as aluminum oxide. Besides using aluminum nitride ceramic, the main body of the heating element 21 can also be made of other ceramic materials, such as alumina or silicon nitride. Besides using tungsten paste, the heating part of the heating element 21 can also be made of other metal pastes, such as silver paste. The battery bracket 23 is disposed within the battery housing 24, and the battery 233 is disposed on the battery bracket 23. The bracket seal 22 is fitted over the upper end of the battery bracket 23 and tightly adheres to the inner wall of the battery housing 24, preventing e-liquid from leaking into the battery device 20 through the gap between the battery housing 24 and the battery bracket 23. A conductive post 231 is disposed at the upper end of the battery bracket 23 and extends into the bracket seal 22; the conductive post 231 is used for electrical connection between the heating element 21 and the battery 233. The bracket seal 22 divides the inner cavity of the battery housing 24 into a receiving cavity 242 located above the bracket seal 22 and a mounting cavity 243 located below the bracket seal 22. The battery bracket 23, the battery 233, and the first control board 29 are all located within the mounting cavity 243. The detection component 25 is partially located within the mounting cavity 243 and partially within the receiving cavity 242. The heating element 21 is located within the receiving cavity 242. Its two leads 211 pass through the bracket seal 22 and are inserted into the conductive post 231, securing the heating element 21 and providing electrical connection with it. The receiving cavity 242 protects the heating element 21 from breakage if the battery device 20 is dropped and it comes into contact with a hard object. Furthermore, the distance between the lowest point of the top of the receiving cavity 242 and the upper surface of the heating element 21 is greater than zero, preventing the user's fingers from touching the heating element 21 and thus preventing burns from residual heat or heat generated during self-cleaning. Please refer to [link to relevant documentation]. Figure 15 and Figure 3The receiving cavity 242 has two opposing cavity walls with latches 241, and the cartridge shell 16 has corresponding slots 11 on its opposite side walls. The latches 241 engage with the slots 11, allowing the cartridge 10 to be detachably mounted on the battery device 20. When the cartridge 10 is mounted on the battery device 20, the cartridge 10 is partially contained within the receiving cavity 242, preventing the cartridge 10 from shaking and improving its installation stability, while also shortening the overall length of the electronic cigarette. Additionally, it should be noted that when the cartridge 10 is in place, the mouthpiece 13 is located outside the battery shell 24 for easy inhalation. Furthermore, the cartridge shell 16 has a sliding groove 1612 on its side wall along the sliding direction of the latches 241 relative to the slots 11. During the installation of the cartridge 10 and the battery device 20, the latches 241 slide along the sliding groove 1612, disengaging from the sliding groove 1612 and engaging with the slots 11. The groove 1612 is designed to guide the installation of the cigarette cartridge 10, making the operation convenient.

[0167] When the cartridge 10 is connected to the battery device 20, the heating element 21 extends into and is located within the atomization chamber 151 to maintain a preset distance or contact the liquid-absorbing element 17, which supplies e-liquid to the heating element 21 for atomization. When the cartridge 10 is installed on the battery device 20, the mating part 153 on the cartridge 10 contacts the detection component 25, and when the cartridge 10 is removed from the battery device 20, the mating part 153 on the cartridge 10 separates from the detection component 25. The detection component 25 is connected to the first control board 29, and the detection component 25 generates a separation signal when separated from the mating part 153. The first control board 29 controls the heating element 21 to operate according to the separation signal and preset parameters to remove residues attached to the heating element 21. The detection component 25 also generates a connection signal when in contact with the mating part 153. At this time, the first control board 29 cannot control the heating element 21 to operate according to the preset parameters to remove residues attached to the heating element 21. Residues include, but are not limited to, residual aerosol-forming matrix and carbonized materials generated at high temperatures. Upon detecting a separation signal, a self-cleaning mode is activated. In practice, this involves controlling the heating element 21 to operate at a higher power for a shorter time, for example, controlling it to operate at a higher power for 0.8 seconds. It should be noted that the power used for self-cleaning is higher than the power of the heating element 21 during atomization. Removing residues from the heating element 21 prevents them from affecting the use of the e-cigarette. For example, if the residue is residual e-liquid, it prevents residual e-liquid from entering the mounting cavity 243 and affecting the electronic components within it. Furthermore, performing self-cleaning only after the cartridge 10 is removed prevents the liquid-absorbing component 17 from carbonizing under the high temperatures during self-cleaning.

[0168] The following provides two implementation methods for the detection component 25.

[0169] In the first embodiment, please refer to Figures 20 to 27 The detection component 25 includes a sensor seal 26, a first cavity 253, a second cavity 254, a first sensor 251, and a second sensor 252. The first cavity 253 and the second cavity 254 are disposed on one side of the battery holder 23 and maintained at a preset distance from the upper end of the battery holder 23. The sensor seal 26 has a first portion 261 and a second portion 262 corresponding to the first cavity 253 and the second cavity 254, respectively. The first sensor 251 is installed in the first portion 261 and placed within the first cavity 253. The opening of the first cavity 253 communicates with the air inlet 152. The second sensor 252 is installed in the second portion 262 and placed within the second cavity 254. The mating portion 153 is a sealing protrusion that protrudes downwards from the lower end face of the base 15, corresponding to the air guide groove 157. When the cartridge 10 is installed on the battery device 20, the mating portion 153 seals the opening of the second cavity 254. The first sensor 251 and the second sensor 252 are respectively connected to the first control board 29 to transmit airflow signals to the first control board 29. Through the cooperative structure of the battery bracket 23, the sensor seal 26 and the first control board 29, the first cavity 253 and the second cavity 254 can be kept separate to avoid airflow interference. When the mating part 153 opens the opening of the second chamber 254 as the cartridge 10 is removed, a negative pressure is generated inside the second chamber 254. This causes the second sensor 252 to detect the change in internal air pressure and generate a corresponding airflow signal, i.e., a high-level signal. Simultaneously, since the user does not inhale when removing the cartridge 10, and the first chamber 253 remains connected to the outside, the air pressure inside the first chamber 253 remains unchanged. Therefore, the first sensor 251 does not detect an airflow signal, i.e., generates a low-level signal. Thus, when the cartridge 10 is removed, the airflow signal of the first sensor 251 is low and the airflow signal of the second sensor 252 is high. When the airflow signal of the first sensor 251 is low and the airflow signal of the second sensor 252 is high, it can be considered that a separation signal of the cartridge 10 being removed from the battery device 20 has been detected. It should be noted that when the types of the first sensor 251 and the second sensor 252 are different, the relevant information used for detecting the airflow is different; it can be the airflow velocity or the air pressure change caused by the airflow. The first sensor 251 and the second sensor 252 generate airflow signals when they detect relevant information about the corresponding airflow.

[0170] Upon detecting a separation signal, a self-cleaning mode is activated. The first control board 29 controls the heating element 21 to operate according to preset parameters to remove residues adhering to it. In practice, the heating element 21 operates at a higher power for a shorter time, for example, heating for 1 second. The power used for self-cleaning is higher than the power used by the heating element 21 during atomization. Removing residues from the heating element 21 prevents them from affecting the use of the e-cigarette. For example, if the residue is residual e-liquid, it prevents residual e-liquid from entering the mounting cavity 243 and affecting the electronic components inside. In addition, self-cleaning is performed only after the cartridge 10 is removed to prevent the liquid absorption element 17 from carbonizing under the high temperature during self-cleaning.

[0171] Following the above, please refer to... Figure 23 as well as Figures 24 to 27 The bracket seal 22 is provided with a socket 224 for inserting the pins of the heating element 21, an air inlet 222 communicating with the opening of the first cavity 253, a through hole 223 communicating with the opening of the second cavity 254, and an air inlet notch 221. The socket 224 is opened on the upper end face of the bracket seal 22, and the air inlet 222 and the through hole 223 are located on opposite sides of the socket 224. The pins of the heating element 21 are inserted into the conductive post 231 after passing through the socket 224. The air inlet notch 221 is opened on the side wall of the bracket seal 22 at a preset distance from the air inlet 222. The mating part 153 of the cartridge 10 closes or opens the opening of the second cavity 254 through the through hole 223 communicating with the opening of the second cavity 254. In addition, please refer to Figure 20 An air inlet groove 12 is provided on the side wall of the cartridge shell 16. The air inlet groove 12 on the cartridge 10 cooperates with the battery shell 24 of the battery device 20 to form an air intake channel, allowing external gas to enter the electronic cigarette. The gas entering the electronic cigarette enters the atomization chamber 151 of the cartridge 10, and carries the smoke in the atomization chamber 151 out through the air guide groove 157, the air guide part 168, the airflow channel 165, and the smoke outlet 131. Please refer to Figure 23The battery casing 24 has a first vent 245, and the battery bracket 23 has a second vent 236 on the side wall at the upper end. The air inlet 221 is connected to the first vent 245 and the second vent 236 respectively. The second vent 236 is also connected to the opening of the first cavity 253. Thus, when the electronic cigarette is inhaled, external gas enters through the first vent 245, the air inlet 221 and the second vent 236. When it flows through the opening of the first cavity 253, it carries away the air in the first cavity 253 and then flows out from the air inlet 222, the air inlet 152, the connecting groove 155, the atomizing cavity 151, the air guide groove 157, the air guide part 168, the airflow channel 165 and the smoke outlet 131, so that a negative pressure is generated in the first cavity 253. The first sensor 251 detects the change in air pressure and generates a corresponding airflow signal, that is, generates a high-level signal. At this time, the opening of the second chamber 254 is closed by the mating part 153, there is no change in air pressure inside the second chamber 254, and the second sensor 252 remains in the state of outputting a low level signal. When the airflow signal of the first sensor 251 is high level and the airflow signal of the second sensor 252 is low level, it is considered that an atomization start signal has been detected. After the atomization start signal is detected, the atomization mode is started. The first control board 29 controls the heating element 21 to work according to the preset parameters to atomize the e-liquid on the liquid suction element 17. It can be understood that the external gas entering from the first vent 245 can also carry away the smoke in the atomization chamber 151 after entering the atomization chamber 151.

[0172] It is important to note that when the user does not perform any inhalation or disassembly / removal operations on the electronic cigarette, there is no change in air pressure within the first chamber 253 and the second chamber 254. Both the first sensor 251 and the second sensor 252 maintain a low-level output signal, and the heating element 21 does not operate; that is, it neither performs self-cleaning nor atomization. When the user only inhales from the battery device 20, the air in both the first chamber 253 and the second chamber 254 is drawn out, resulting in negative pressure within both chambers. Both the first sensor 251 and the second sensor 252 generate high-level signals. At this time, the heating element 21 also does not operate, thus preventing it from working under abnormal conditions.

[0173] To prevent condensate from the smoke or leaked smoke from entering the first chamber 253 and the second chamber 254, thus affecting the operation of the first sensor 251 and the second sensor 252. For example... Figure 27 As shown, the upper end face of the battery holder 23 is recessed downwards to form a first receiving groove 237 and a second receiving groove 238. A connecting portion 239 protrudes upwards along the axial direction of the battery device 20 on the bottom wall of the first receiving groove 237, and the connecting portion 239 communicates with both the opening of the first receiving groove 237 and the opening of the first cavity 253. Please refer to... Figure 25A partition 229 protrudes downwards from the upper end surface of the bracket seal 22. When the bracket seal 22 is installed in place, the air inlet 222 and the connecting part 239 are located on opposite sides of the partition 229, that is, the air inlet 222 and the connecting part 239 are staggered. Because the connecting part 239 protrudes and the air inlet 222 and the connecting part 239 are staggered, even if the condensate of the smoke or the leaked smoke liquid enters the battery device 20, it cannot enter the first cavity 253 through the air inlet 222 and the connecting part 239, but remains in the first receiving groove 237. Under the user's suction, external gas enters the first receiving groove 237 through the first vent 245, the air inlet 221, and the second vent 236, and then flows out through the air inlet 222, the air inlet 152, the connecting groove 155, the atomizing chamber 151, the air guide groove 157, the air guide part 168, the airflow channel 165, and the smoke outlet 131. During this process, the air in the first chamber 253 is carried out by the external gas through the opening of the first chamber 253, the connecting part 239, and the first receiving groove 237, resulting in a negative pressure in the first chamber 253. The first sensor 251 detects the change in air pressure and generates a corresponding airflow signal, i.e., a high-level signal. It can be understood that in other embodiments not shown, a waterproof and breathable membrane can also be provided at the opening of the first chamber 253. In this way, the air in the first chamber 253 can be smoothly sucked out, while liquids such as condensate or leaked smoke liquid are isolated outside the first chamber 253 by the waterproof and breathable membrane. Alternatively, a deformable element can be provided at the opening of the first cavity 253. Under the user's suction, the deformable element deforms, increasing the space enclosed by the first cavity 253 and the deformable element. This reduces the air pressure within the space, and the first sensor 251 detects the pressure change, generating a corresponding airflow signal. When suction stops, the deformable element returns to its original shape, and the air pressure in the space recovers. The deformable element isolates condensate or leaked e-liquid outside the first cavity 253. In this embodiment, the detection component 25 also includes a deformable portion 225, which is formed by a portion of the upper surface of the support seal 22 that protrudes downwards corresponding to the through hole 223. The deformable portion 225 is a hollow structure with an open upper end. Please refer to... Figure 23When the bracket seal 22 is installed on the battery bracket 23, the deformable part 225 extends into and is located in the second receiving groove 238. The bottom wall of the second receiving groove 238 is provided with a connecting hole 230, which communicates with the opening of the second cavity 254 and the second receiving groove 238 respectively. The deformable part 225 closes the opening of the second cavity 254 by closing the connecting hole 230. At this time, the deformable part 225 and the second cavity 254 cooperate to form a sealed space to accommodate the second sensor 252. When the cartridge 10 is installed in place, the mating part 153 is inserted into the deformable part 225 through the through hole 223 to seal the deformable part 225, which is equivalent to sealing the opening of the second cavity 254. When the cartridge 10 is pulled out, the deformable part 225 deforms under the action of the mating part 153. The sealed space formed by the second cavity 254 and the deformable part 225 increases, creating a negative pressure within the space. The second sensor 252 detects the change in air pressure and generates a corresponding airflow signal, i.e., a high-level signal. The deformable part 225 isolates the second sensor 252 inside the second cavity 254 from the outside, thus preventing condensate or leaked e-liquid from entering the second cavity 254 and affecting the normal operation of the second sensor 252.

[0174] Understandably, the deformable part 225, as part of the detection component 25, can also be directly mounted on the battery holder 23 and located at the opening of the second cavity 254, and cooperate with the second cavity 254 to form a sealed space for accommodating the second sensor 252. In this case, the through hole 223 on the bracket seal 22 is configured to penetrate the upper end face and the lower end face of the bracket seal 22, so that when the cartridge 10 is installed in place, the mating part 153 is inserted into the deformable part 225 through the through hole 223 to seal the deformable part 225. At the same time, the deformable part 225 can isolate the second sensor 252 in the second cavity 254 from the outside world, preventing the condensate or leaked e-liquid from entering the second cavity 254. Furthermore, the second sensor 252 generates an airflow signal by detecting changes in air pressure within its cavity. Therefore, it is sufficient to ensure that there is no change in air pressure within the cavity where the second sensor 252 is located after the cartridge 10 is installed, but a change in air pressure occurs when the cartridge 10 is removed. The change in air pressure can be caused directly by the mating part 153 being pulled out relative to the second cavity 254 when the deformable part 225 is not provided, or by the change in air pressure acting on the deformable part 225 when the mating part 153 is pulled out relative to the second cavity 254 when the deformable part 225 is provided. In this case, the opening of the deformable part 225 is the opening of the second cavity 254. Correspondingly, the opening of the second cavity 254 is in a closed state after the cartridge 10 is installed, and in an open state after the cartridge 10 is removed, thereby generating the aforementioned change in air pressure.

[0175] The battery device 20 is equipped with a dual sensor structure that can cooperate with the mating part 153 on the cartridge 10 to generate a signal when the cartridge 10 is removed. This allows the electronic cigarette to automatically remove residues from the heating element 21 when the cartridge 10 is removed, achieving self-cleaning and improving the service life of the heating element 21 and the electronic components in the battery device 10.

[0176] In the second embodiment, a mating portion 153 is formed on the lower end face of the base 15 opposite to the air inlet 152. The detection component 25 includes a state detection circuit (not shown in the figure). The state detection circuit is used to detect the installation state of the cartridge 10. When the cartridge 10 is installed on the battery device 20, the state detection circuit and the mating portion 153 are engaged and in a conductive state. When the cartridge 10 is removed from the battery device 20, the state detection circuit and the mating portion 153 are disengaged and in a disconnected state. The disconnection signal of the state detection circuit corresponds to the separation signal generated when the cartridge 10 is removed from the battery device 20. In this embodiment, the state detection circuit is provided with a switching element 653. When the cartridge 10 is installed on the battery device 20, the mating portion 153 drives the switching element 653 to conduct the state detection circuit. When the cartridge 10 is removed from the battery device 20, the switching element 653 separates from the mating portion 153 and resets, causing the state detection circuit to disconnect and generate a separation signal.

[0177] Please see Figure 13In actual implementation, the switching element 653 includes a pin 651 and a switch button 652. The battery device 20 has a pin mounting through hole (not shown in the figure) on the side where the cartridge 10 is installed. The pin 651 passes through the pin mounting through hole and protrudes beyond the bracket seal 62 and corresponds to the position of the mating part 153 on the cartridge 10. The pin 651 is connected to an elastic element and can automatically reset after the external force is removed. The switch button 652 is set on the first control board 29 where the state detection circuit is located and corresponds to the position of the pin 651. The switch button 652 is connected to an elastic element and can automatically reset after the external force is removed. When the cartridge 10 is installed on the battery device 20, the mating part 153 presses the switch button 652 to the closed position through the pin 651. When the cartridge 10 is removed from the battery device 20, the pin 651 resets under the action of the corresponding elastic element, thereby causing the switch button 652 to reset to the open position under the action of the corresponding elastic element. At this time, the state detection circuit is disconnected and a separation signal is generated. The elastic element connected to the ejector pin 651 can be omitted. During the process of the switch button 652 resetting to the open position under the action of the corresponding elastic element, the switch button 652 can drive the ejector pin 651 to reset. The mating part 153 that can push the ejector pin 651 can be a surface, groove, or protrusion of the base 15 of the cartridge 10, as long as it can press the ejector pin 651 down with the movement of the cartridge 10, without any shape limitation. Understandably, the reset element that drives the ejector pin 651 and the switch button 652 to reset can be other elements besides the elastic element, such as a magnetic element. Specifically, the switch button 652 is provided with a pair of magnetically repulsive elements. In its natural state, under the action of repulsive force, the switch button 652 is in the open position. When the ejector pin 651 presses the switch button 652, by overcoming the repulsive force, the switch button 652 is pressed to the closed position.

[0178] Understandably, the structure of the switching element 653 in this embodiment is not limited to this. For example, the switching element 653 may be simply a switch button, and the mating part 153 provided on the cartridge 10 may be a push rod. When the cartridge 10 is installed, the push rod on the cartridge 10 can press the switch button to the closed position. When the cartridge 10 is removed from the battery device 20, the push rod leaves the switch button, and the switch button resets under the action of the corresponding elastic element to disconnect the state detection circuit. Alternatively, the switching element 653 may be simply a switch button, the top of which protrudes outside the bracket seal 22. The mating part 153 provided on the cartridge 10 may be a plane or a groove. When the cartridge 10 is installed, the cartridge 10 can directly press the switch button to the closed position. When the cartridge 10 is removed from the battery device 20, the cartridge 10 leaves the switch button, and the switch button resets under the action of the corresponding elastic element to disconnect the state detection circuit.

[0179] The battery device 20 is equipped with a status detection circuit and a resettable switch element 653, which can cooperate with the mating part 153 on the cartridge 10 to generate a signal when the cartridge 10 is removed. This allows the electronic cigarette to automatically remove residues from the heating element 21 when the cartridge 10 is removed, achieving self-cleaning and improving the service life of the heating element 21 and the electronic components in the battery device 20.

[0180] In both of the above embodiments, the mating part contacts the detection component when the cartridge is installed on the battery device and separates from the detection component when the cartridge is removed from the battery device. The detection component generates a separation signal when separated from the mating part and a connection signal when in contact with the mating part. It is understood that in other embodiments not shown, the mating part and the detection component can also use other mating methods, as long as the detection component generates a separation signal when the cartridge is removed from the battery device and a connection signal when the cartridge is connected to the battery device. For example, the mating part and the detection component may never contact each other. Specifically, the detection component includes a light source and a light sensor. When the cartridge is installed on the battery device, the light beam generated by the light source is reflected by the mating part, causing the light sensor to detect the light beam and generate a connection signal. When the cartridge is removed, the light beam is no longer reflected, causing the light sensor to detect the disappearance of the light beam and generate a separation signal.

[0181] Please refer to it again. Figure 12 , Figure 13The battery holder 23 has a cavity 61. The battery device 20 also includes a sensor seal 26 and a sensor 66. The sensor 66 is connected to the first control board 29 and installed in the sensor seal 26 and placed in the cavity 61. The cavity 61 is connected to the mouthpiece 13. The sensor 66 is used to detect the airflow state in the cavity 61. When the user inhales, the air in the cavity 61 is drawn out, creating a negative pressure in the cavity 61. The sensor 66 generates an airflow signal. The first control board 29 controls the heating element 21 to perform atomization based on the airflow signal. Thus, when the state detection circuit is on, the electronic cigarette confirms that the cartridge 10 is in the installed state. At this time, it determines whether the user is inhaling based on the airflow signal from the sensor 66. When the user inhales the electronic cigarette, the air in the cavity 61 is drawn out, and the cavity 61 is in a negative pressure state. The sensor 66 generates a high-level airflow signal. At this time, the first control board 29 controls the battery 233 to supply power to the heating element 21 so that the heating element 21 generates heat and performs atomization. It should be noted that after receiving the separation signal indicating that the cartridge 10 has been removed from the battery device 20, the first control board 29 indicates that the cartridge 10 has been removed. At this time, even if a high-level airflow signal is detected, the first control board 29 will not control the battery 233 to supply power to the heating element 21. That is, the heating element 21 cannot perform atomization, which effectively provides child protection and prevents the battery device 20 from being accidentally triggered when only the opening of the battery device 20 is sucked in. In this embodiment, the sensor 66 is an airflow sensor, used to generate an airflow signal when airflow flows. It can be understood that in other embodiments not shown, the sensor 66 is a pressure sensor, used to generate an airflow signal when airflow causes negative pressure to be generated in the cavity 61. It can be understood that when the type of sensor 66 is different, the relevant information of the airflow to be detected is different, which can be the airflow velocity or the air pressure change caused by the airflow. The sensor 66 generates an airflow signal when it detects the corresponding airflow-related information. Understandably, the aforementioned airflow signal constitutes a suction signal. That is, when the detection component 25 generates a connection signal and the sensor 66 generates a suction signal, the first control board 29 controls the battery 233 to supply power to the heating element 21, so that the heating element 21 performs atomization.

[0182] Please see Figure 10 , Figure 11A protrusion 226 extends upward along the axial direction of the upper end face of the bracket seal 22, forming a protrusion 226. The top of the protrusion 226 is recessed downward to form a liquid collection groove 2211. Two insertion holes 224 are provided at the top of the liquid collection groove 2211, penetrating the upper and lower end faces of the bracket seal 22. The two leads 211 of the heating element 21 pass through the insertion holes 224 and are connected to the corresponding conductive posts 231, thus achieving electrical conductivity. During actual use, the condensate generated when the smoke cools can be collected in the liquid collection groove 2211, preventing the condensate from entering the battery device 20 and damaging other components. Furthermore, the liquid collection groove 2211 is positioned at a preset distance from the heating element 21. The heat generated by the heating element 21 after being energized can atomize the condensate in the liquid collection groove 2211, achieving a cleaning effect on the condensate in the liquid collection groove 2211. It should also be noted that when the cartridge 10 is installed, the protrusion 226 is inserted into the atomizing chamber 151, and the wall of the atomizing chamber 151 is in contact with the outer surface of the protrusion 226. In this way, the condensate in the atomizing chamber 151 can only enter the collection tank 2211 and will not leak to other places.

[0183] An air inlet 221 is provided on the upper end face of the bracket seal 22, on one side of the protrusion 226, and the air inlet 221 corresponds to the air inlet 152. A vent 245 is provided on the side wall of the battery housing 24, which is connected to the outside atmosphere and the air inlet 221. A sensing tube 2212 is provided on the upper end face of the battery bracket 23. The sensing tube 2212 is a tubular structure with both ends open. The inner cavity of the sensing tube 2212 forms a sensing channel 2213. The lower end of the sensing channel 2213 is connected to the cavity 61. The upper end of the sensing tube 2212 passes through the bracket seal 22 and extends into the air inlet 221. When the cartridge 10 and battery device 20 are installed, the air intake notch 221 and the sensing channel 2213 are both connected to the air intake port 152. When the user inhales the electronic cigarette, external gas enters the air intake notch 221 through the air vent 245. When it flows through the upper port of the sensing channel 2213, it carries away the air in the cavity 61 and then flows out from the air intake port 152, the connecting groove 155, the atomizing chamber 151, the air guide groove 157, the air guide part 168, the airflow channel 165, and the smoke outlet 131, creating a negative pressure in the cavity 61. The sensor 66 generates an airflow signal. At this time, the first control board 29 controls the battery 233 to supply power to the heating element 21 so that the heating element 21 generates heat after being powered on, thereby performing atomization. The external gas flowing into the atomizing chamber 151 can carry smoke out from the air guide groove 157, the air guide part 168, the airflow channel 165, and the smoke outlet 131 for the user to inhale. Additionally, a waterproof and breathable membrane (not shown) can be installed at the upper opening of the sensing tube 2212 to prevent condensate from entering the cavity 61 and thus preventing condensate from contacting the sensor 66, while allowing air to be smoothly drawn in from the cavity 61, enabling the sensor 66 to detect airflow-related information. Understandably, the waterproof and breathable membrane can also be placed in other locations, as long as it isolates the sensor 66 from the air inlet 152. For example, the waterproof and breathable membrane can be placed in the cavity 61 or in the sensing channel 2213. Understandably, in other embodiments not shown, a deformable member can also be provided corresponding to the opening of the cavity 61. The sensor 66 is located within the space formed by the deformable member and the cavity 61. When the user inhales, the deformable member deforms, increasing the volume of the space and decreasing the air pressure within it. The sensor 66 detects the change in air pressure and generates a corresponding airflow signal. When inhalation stops, the deformable member returns to its original shape, and the air pressure in the space recovers. The deformable member isolates condensate or leaked e-liquid outside the cavity 61.

[0184] Please refer to it again. Figure 2In this embodiment, the opening of the battery housing 24 is set at an angle, and one surface of the mouthpiece 13 is correspondingly set at an angle. When the cartridge 10 and the battery device 20 are installed in place, the angle of the battery housing 24 and the angle of the mouthpiece 13 cooperate with each other. Thus, when the cartridge 10 is installed, it can only be inserted into the receiving cavity 242 in a single direction, ensuring that the sensing channel 2213 can correspond to the air inlet 152 after the cartridge 10 is inserted. Specifically, the battery housing 24 has a first end (not shown in the figure) and a second end (not shown in the figure) that are arranged opposite to each other. The second end is an open end, and the cartridge 10 is detachably inserted into the battery housing 24 through the open end. In order to prevent the user from arbitrarily touching the heating element 21 and causing unnecessary burns, the distance from the lowest point of the open end to the upper surface of the heating element 21 is greater than zero, so that the heating element 21 is located in the receiving cavity 242. The diameter of the open end is small, making it difficult for the user's fingers to insert, thereby preventing the user from touching the heating element 21. The battery housing 224 has a first limiting part (not shown) and a second limiting part (not shown), the distance from the first limiting part to the first end is less than the distance from the second limiting part to the first end. Correspondingly, the mouthpiece 13 is provided with a first positioning part (not shown) and a second positioning part (not shown), the distance from the first positioning part to the suction end is greater than the distance from the second positioning part to the suction end. When the cartridge 10 and the battery device 20 are assembled, the first positioning part abuts against the first limiting part, and the second positioning part abuts against the second limiting part. If, during assembly, the first positioning part is opposite to the second limiting part, and the second positioning part is opposite to the first limiting part, the cartridge 10 cannot be installed in place. In this embodiment, the two opposing surfaces of the battery housing 24 constitute a first limiting surface and a second limiting surface, both extending from the first end along the axial direction of the battery device 20 to the second end, and the distance the first limiting surface extends axially along the battery device 20 is less than the distance the second limiting surface extends axially along the battery device 20. The side of the first limiting surface located at the second end is the first limiting portion, and the side of the second limiting surface located at the second end is the second limiting portion. Correspondingly, the two opposing surfaces of the mouthpiece 13 constitute the first positioning surface and the second positioning surface. Both the first positioning surface and the second positioning surface extend along the axial direction of the cartridge 10 from the inhalation end, and the distance the first positioning surface extends along the axial direction of the cartridge 10 is greater than the distance the second positioning surface extends along the axial direction of the cartridge 10. The side of the first positioning surface away from the inhalation end is the first positioning portion, and the side of the second positioning surface away from the inhalation end is the second positioning portion. It is understood that in other embodiments, the first limiting portion and the second limiting portion can also adopt other arrangement methods, as long as they are not symmetrically arranged along the central axis of the battery device 20. Similarly, the first positioning portion and the second positioning portion can be arranged symmetrically along the central axis of the cartridge 10.For example, the first limiting part and the second limiting part can be located on the same side of the opening end of the battery housing 24. Specifically, this side is a sloping side, with the lower end of the sloping side being the first limiting part and the higher end of the sloping side being the second limiting part. Correspondingly, the first positioning part and the second positioning part are located on the same side of the mouthpiece 13 away from the suction end. This side is a sloping side, with the end of the sloping side farther from the suction end being the first positioning part and the end of the sloping side closer to the suction end being the second positioning part.

[0185] Please refer to it again. Figure 11 In one specific embodiment, the heating element 21 has at least one through groove 212 extending through both the upper and lower surfaces of the heating element 21, facilitating the flow of vapor through the heating element 21. Furthermore, when the cartridge 10 is installed, the liquid-absorbing component 17 can deform under external force and partially accommodate itself within the through groove 212. Thus, the liquid-absorbing component 17 can contact not only the surface of the heating element 21 but also the wall of the through groove 212, increasing the contact area between the heating element 21 and the liquid-absorbing component 17, thereby improving atomization efficiency. The through groove 212 has a length of 1-2 mm and a width of 0.2-0.5 mm. On the one hand, the length of the through groove 212 needs to be shorter than the maximum length of the heating element 21, leaving space for mounting pins 211 at both ends of the heating element 21. On the other hand, the narrow width of the through groove 212 prevents leakage of e-liquid through the through groove 212.

[0186] Furthermore, the heating element 21 is in the form of a thin sheet, with a thickness of 0.2-3 mm. In one specific embodiment, the thickness of the heating element 21 is 0.45-0.55 mm. If the heating element 21 is too thick, it will hinder heat conduction; if it is too thin, its strength will be insufficient, and the heating element 21 will be prone to breakage. The maximum width of the heating element 21 is selected from 1.5-4.5 mm, and in one specific embodiment, the maximum width of the heating element 21 is selected from 2.5-3.5 mm. The maximum length of the heating element 21 is selected from 2.5-13.5 mm, and in one specific embodiment, the maximum length of the heating element 21 is selected from 4-5 mm. The maximum width and maximum length of the heating element 21 are within the above ranges, ensuring that the heating element 21 can smoothly pass through the lower opening of the atomizing chamber 151 and that the heating element 21 has a sufficient heating area. The heating element 21 has through holes on both sides (not shown in the figure), and the through groove 212 is located between the two through holes. After the pin 211 is inserted into the through hole, it is welded and fixed to the heating element 21. The pin 211 is made of hard material so that the heating element 21 will not be deformed or shifted due to pressure during the installation of the cartridge 10.

[0187] Additionally, please see Figure 14The conductive post 231 used to mount the heating element 21 is an elastic conductive post. Thus, during installation, the heating element 21 and the liquid-absorbing element 17 make elastic contact, allowing for a certain degree of processing error while ensuring a close fit between the heating element 21 and the liquid-absorbing element 17. In one specific embodiment, the conductive post 231 includes a first connecting portion and a second connecting portion. The first connecting portion is fixed relative to the heating element 21, and the second connecting portion is fixed relative to the battery device body. The first connecting portion can move away from or towards the second connecting portion under external force. Specifically, the first connecting portion is a fixing tube 2314 and a claw 2315 installed in one end of the fixing tube 2314, and the second connecting portion is an outer sleeve 2311, with the fixing tube 2314 movably disposed within the outer sleeve 2311. The conductive post 231 also includes an elastic element 2312 and an insulating element 2313 housed within the outer sleeve 2311. One end of the elastic element 2312 elastically abuts against the lower end of the outer sleeve 2311, and the other end of the elastic element 2312 elastically abuts against the insulating element 2313. The lower end of the fixing tube 2214 contacts the insulating element 2213. When the fixing tube 2314 is pressed, it can compress the elastic element 2312 through the insulating element 2313 and retract into the outer sleeve 2311. When the pressing action on the fixing tube 2314 is released, the fixing tube 2314 retracts into the elastic element 2312. Under the reset action of 312, it moves upward and partially extends out of the outer sleeve 2311. The claw 2315 includes a clamp 2317 fixedly connected to the inner wall of the outer sleeve 2311 and a holding part 2318 installed on the lower end face of the clamp 2317. The end of the holding part 2318 relative to the clamp 2317 is bent towards the central axis of the clamp 2317. The holding part 2318 is an elastic element. When the pin 211 of the heating element 21 is installed, the pin 211 passes through the clamp 2317 and is squeezed by the holding part 2318, thereby fixing the heating element 21. The operation is simple and convenient. In addition, the insulating part 2313 is disposed between the elastic element 2312 and the fixing tube 2314, so that the elastic element 2312 and the fixing tube 2314 are isolated from each other by the insulating part 2313 and do not contact each other. The insulating part 2313 is made of insulating material. The small size of the conductive post 231 results in a very small elastic element 2312 installed inside it. If current were to flow through the elastic element 2312, it would easily burn out. Thanks to the insulating element 2313, when energized, the current does not flow through the elastic element 2312, but instead flows through the outer sleeve 2311, the fixing tube 2314, and the claw 2315. This prevents the elastic element 2312 from overheating and being damaged when the heating element 21 is working. Furthermore, the insulating element 2313 is an insulating ball that positions the elastic element 2312, preventing it from shifting position during repeated pressing and resetting, which could lead to its failure.Understandably, the elastic element 2312 includes, but is not limited to, elements with both elasticity and rigidity, such as springs, stainless steel springs, or copper springs.

[0188] Please see Figure 12 , Figure 13 and Figure 15 In this invention, battery 233 is a rechargeable battery. Battery device 20 has a charging connection portion (not shown in the figure) on the side away from the heat-generating element 21. The charging connection portion includes a second control board 235, a connecting post 281, and a contact electrode 282. The contact electrode 282 is connected to the second control board 235 via the connecting post 281. Battery bracket 23 has a through hole for exposing the contact electrode 282. Correspondingly, please refer to [reference needed]. Figure 16 , Figure 17 A charging base 40 for charging a battery 233 includes an electronic cigarette connection part 41 and a power connection part 42. The electronic cigarette connection part 41 includes an electronic cigarette slot 411 and a charging post 412 located in the electronic cigarette slot 411. The electronic cigarette slot 411 is used to fix the electronic cigarette, and the charging post 412 is used to electrically connect to the contact electrode 282 on the battery device 20. The power connection part 42 is provided with a charging interface, such as a USB interface or plug. The electronic cigarette connection part 41 and the power connection part 42 are at a set angle, 90° < set angle < 180°, for example, 155°, so as to avoid interference between the electronic cigarette and protruding objects on the wall when charging, and also to facilitate the user's access.

[0189] Please refer to it again. Figure 12 , Figure 13 and Figure 15 To allow users to clean the residue on the heating element 21 as needed, in this embodiment, the battery device 20 is also provided with an operation part 27. The operation part 27 is connected to the second control board 235 and is used to trigger the second control board 235 to control the heating element 21 to work according to preset parameters to clean the residue on the heating element 21 under the operation of the user. The lower end of the battery bracket 23 is provided with a through hole for accommodating the operation part 27. When the self-cleaning function is needed, the user can press the operation part 27 by inserting a tool into the through hole to trigger it. The operation part 27 is designed to be concealed, thereby avoiding accidental operation.

[0190] In addition, please see Figure 1 , Figure 12 and Figure 13 To help users understand the usage status of the electronic cigarette, the battery device 20 is also equipped with an indicator light 30. The indicator light 30 is fixed on the battery bracket 23 by the lamp post cover 232 and connected to the first control board 29. The battery housing 24 is provided with a through hole for observing the indicator light 30.

[0191] The control method of the electronic cigarette in the above embodiments will be described in detail below.

[0192] Please see Figure 19 The electronic cigarette control method of this embodiment includes, but is not limited to, the following steps:

[0193] Step S1: Detect the separation signal generated when the cartridge is removed from the battery device. The cartridge contains an aerosol forming matrix, and the battery device is equipped with a heating element for heating the aerosol forming matrix in the cartridge when powered on.

[0194] Step S2: When a separation signal is detected, the heating element is controlled to operate to remove the residue on the heating element.

[0195] The electronic cigarette of the present invention includes a cartridge and a battery device, which are detachably connected. The cartridge stores an aerosol-forming matrix, which can be a substance capable of producing inhalable vapor, such as e-liquid, tobacco paste, or tobacco shreds. The battery device is equipped with a heating element, which heats the aerosol-forming matrix in the cartridge to form vapor when powered on. When the cartridge is removed from the battery device, the cartridge separates from the heating element, at which point residues left from use may adhere to the heating element. These residues may include, for example, the aerosol-forming matrix remaining on the heating element or carbon deposits generated during heating. In one embodiment, the aerosol-forming matrix is ​​e-liquid, and the cartridge is equipped with a corresponding liquid-absorbing element to supply e-liquid to the heating element. When the cartridge is installed on the battery device, the liquid-absorbing element contacts or approaches the heating element, thereby supplying the e-liquid stored in the cartridge to the heating element for atomization.

[0196] Corresponding to the first embodiment described above, when the battery device is equipped with a first sensor and a second sensor, the step of detecting the separation signal generated when the cartridge is removed from the battery device includes:

[0197] The first airflow signal from the first sensor and the second airflow signal from the second sensor are acquired. The first sensor is disposed in the first cavity of the battery device, and the second sensor is disposed in the second cavity of the battery device. The first cavity is connected to the airflow channel of the electronic cigarette and isolated from the second cavity. The second cavity is in a closed state when the cartridge is installed on the battery device and in an open state after the cartridge is removed from the battery device.

[0198] If the first airflow signal is low and the second airflow signal is high, a separation signal generated when the cartridge is removed from the battery device is detected.

[0199] The first sensor is disposed in a first cavity of the battery device, and the second sensor is disposed in a second cavity of the battery device. The first cavity is connected to the airflow channel of the electronic cigarette, but the first and second cavities are isolated from each other. The second cavity is in a sealed state when the cartridge is installed on the battery device and in an open state after the cartridge is removed from the battery device. In actual implementation, the cartridge is provided with a sealing part, which is inserted into the opening of the second cavity and seals the opening when the cartridge is installed on the battery device. Thus, when the cartridge is removed from the battery device, negative pressure will be generated in the second cavity due to the removal of the sealing part. The pressure causes airflow disturbance, and the second airflow signal of the second sensor is a high-level signal. At the same time, since the user does not inhale when removing the cartridge, there is no airflow in the airflow channel of the electronic cigarette, and the removal of the cartridge does not cause a change in air pressure in the first chamber. Therefore, the first airflow signal of the first sensor is a low-level signal. Thus, when the first airflow signal is low and the second airflow signal is high, it can be considered that the cartridge is currently being removed from the battery device. The first airflow signal being low and the second airflow signal being high is equivalent to the separation signal of the cartridge being removed from the battery device.

[0200] When a separation signal is detected, the e-cigarette controls the heating element to operate and remove residue. In practice, the e-cigarette controls the heating element according to preset parameters, thereby activating a self-cleaning mode to remove residue. These preset parameters include one of the following: preset operating voltage, preset temperature, preset power, and preset operating duration. The preset operating voltage is higher than the operating voltage of the e-cigarette when inhaled; it can also be equal to the current output voltage of the battery. The preset temperature is higher than the operating temperature of the e-cigarette when inhaled, which is also the atomization temperature of the heating element during normal operation. The preset power is higher than the operating power of the e-cigarette when inhaled, which is also the atomization power of the heating element during normal operation. By using a higher operating voltage, operating temperature, or operating power, the attached residue can be consumed quickly in a shorter time. The preset operating duration is a relatively short duration, such as 1 second. Of course, in practice, controlling the heating element according to the operating parameters corresponding to the e-cigarette when inhaled can also remove residue; the only difference is the time required for removal.

[0201] When the battery device is equipped with a first sensor and a second sensor located in the first cavity and the second cavity respectively, the control method of the electronic cigarette may further include the following steps:

[0202] If both the first airflow signal and the second airflow signal are at a low level or both are at a high level, the heating element will not work.

[0203] If both the first and second airflow signals are low, it indicates that the e-cigarette is idle and the heating element is not working. When the e-cigarette is inhaled without a cartridge installed, airflow passes through both the first and second chambers, and both the first and second airflow signals are high. If a child obtains the e-cigarette and inhales at this time, the heating element could be activated, causing burns. Therefore, when both the first and second airflow signals are high, the heating element is not working.

[0204] When the battery device is equipped with a first sensor and a second sensor located in the first cavity and the second cavity respectively, the control method of the electronic cigarette may further include the following steps:

[0205] If the first airflow signal is high and the second airflow signal is low, the heating element is controlled to work according to the working parameters corresponding to the electronic cigarette in the inhalation state.

[0206] When a user inhales an e-cigarette, airflow passes through the e-cigarette's airflow channel. The first sensor generates a high-level airflow signal. This, combined with the airflow signal from the second sensor, determines whether the cartridge is currently installed. The second sensor will not detect airflow changes only if the second chamber is closed during inhalation. Therefore, if the second airflow signal is low, it indicates the second chamber is closed and the cartridge is installed. Thus, when both the first and second airflow signals are high, it indicates the cartridge is installed and the user is inhaling. At this time, the e-cigarette controls the heating element according to the operating parameters corresponding to the inhalation state, thus controlling the heating element to perform normal atomization.

[0207] After controlling the heating element to operate according to the operating parameters corresponding to when the electronic cigarette is in the inhalation state, the control method of the electronic cigarette may also include the following steps:

[0208] If the time it takes for the resistance of the heating element to rise to the preset resistance value is less than the preset time, then the heating element will be controlled to stop working.

[0209] If the time it takes for the resistance of the heating element to rise to the preset resistance value is greater than or equal to the preset time, the output power of the heating element is controlled so that the resistance of the heating element remains at the preset resistance value.

[0210] The preset resistance value is the atomization resistance value when the e-cigarette is atomizing. This is the normal operating resistance value. Typically, an e-cigarette is set with an atomization temperature at the factory, which corresponds to the resistance value of a heating element. When the e-cigarette is working, the battery device outputs voltage to the heating element to make it work and monitors the resistance value of the heating element in real time. When the resistance value of the heating element reaches the resistance value corresponding to the preset atomization temperature, the output power is controlled to stabilize the resistance value of the heating element at that value, which is the aforementioned atomization resistance value. Of course, the atomization resistance value can also be calculated based on the atomization temperature or power set by the user. During the heating process of an electronic cigarette, if the time it takes for the resistance of the heating element to rise to the preset resistance value is less than the preset time, it indicates that the heating element is heating up too quickly due to dry burning. To protect the cartridge, heating is stopped at this time. If the time it takes for the resistance of the heating element to rise to the preset resistance value is greater than or equal to the preset time, it indicates that the heating element is working normally. At this time, the output power of the heating element is controlled to stabilize the resistance of the heating element at the preset resistance value. Stable resistance means that the deviation of the resistance of the heating element from the preset resistance value is within a small range.

[0211] In another embodiment, corresponding to the second embodiment described above, when a state detection circuit is provided on the battery device, step S1 detects the separation signal generated when the cartridge is removed from the battery device, including:

[0212] The on / off signal of the status detection circuit is obtained. The status detection circuit is used to detect the installation status of the tobacco cartridge. The status detection circuit is set on the battery device. The status detection circuit is in the on state when the tobacco cartridge is installed on the battery device, and in the off state when the tobacco cartridge is separated from the battery device.

[0213] If the on / off signal is a disconnect signal, a separation signal generated when the cartridge is removed from the battery device is detected.

[0214] The status detection circuit is located on the battery device to detect the installation status of the cartridge. In this embodiment, the status detection circuit includes a switching element for turning the status detection circuit on and off. The switching element includes an elastic element and a switch button connected to the elastic element. When the cartridge is installed on the battery device, the cartridge presses the switch button on the switching element by pressing the pin or rod on the battery device. The elastic element in the switching element is in a deformed state, the switching element closes, and the status detection circuit is turned on. At this time, the on / off signal of the status detection circuit is a conducting signal, that is, the status detection circuit changes from an off state to a conducting state. The electronic cigarette then recognizes that it has detected the installation signal of the cartridge or considers the cartridge to be in the installation state. When the cartridge is pulled out of the battery device, the cartridge no longer presses the pin or rod, the external force on the switch button is removed, the elastic element in the switching element recovers its deformation, the switch button resets, and the status detection circuit is turned off. At this time, the on / off signal of the status detection circuit is a disconnected signal, that is, the status detection circuit changes from a conducting state to a disconnected state. The electronic cigarette then detects the separation signal of the cartridge.

[0215] When a separation signal is detected, the e-cigarette controls the heating element to operate and remove residue. In practice, the e-cigarette controls the heating element according to preset parameters to remove residue. These preset parameters include one of the following: preset operating voltage, preset temperature, preset power, and preset duration. The preset operating voltage is higher than the operating voltage of the e-cigarette when inhaled; it can also be equal to the current output voltage of the battery. The preset temperature is higher than the operating temperature of the e-cigarette when inhaled, which is also the atomization temperature of the heating element during normal operation. The preset power is higher than the operating power of the e-cigarette when inhaled, which is also the atomization power of the heating element during normal operation. By using a higher operating voltage, operating temperature, or operating power, the attached residue can be consumed quickly in a shorter time. For example, the preset operating duration can be a short duration, such as 1 second. Of course, in practice, controlling the heating element according to the operating parameters corresponding to the e-cigarette when inhaled can also remove residue.

[0216] When the battery device is equipped with a state detection circuit and a sensor, the control method for the electronic cigarette may further include the following steps:

[0217] When the cartridge is in the installed state, a third airflow signal from the sensor is acquired. The sensor is located in a cavity on the battery device, and the cavity is connected to the airflow channel of the electronic cigarette.

[0218] If the third airflow signal is high, the heating element will be controlled to work according to the working parameters corresponding to when the electronic cigarette is in the inhalation state.

[0219] When the status detection circuit on the battery device is on, the e-cigarette confirms that the cartridge is installed. At this time, it determines whether the user is inhaling based on the airflow signal from the sensor. When the user inhales, airflow passes through the e-cigarette's airflow channel, and the airflow signal generated by the sensor is high. At this time, the e-cigarette controls the heating element to operate according to the operating parameters corresponding to the inhalation state, i.e., controlling the heating element to perform normal atomization. It should be understood that after detecting a separation signal indicating that the cartridge has been removed from the battery device, it indicates that the cartridge has been removed and is in an uninstalled state. In this case, even if the third airflow signal is high, the heating element will not be activated.

[0220] After controlling the heating element to operate according to the operating parameters corresponding to when the electronic cigarette is in the inhalation state, the control method of the electronic cigarette may also include the following steps:

[0221] If the time it takes for the resistance of the heating element to rise to the preset resistance value is less than the preset time, then the heating element will be controlled to stop working.

[0222] If the duration for which the resistance of the heating element rises to the preset resistance value is greater than or equal to the preset duration, the output power of the heating element is controlled so that the resistance of the heating element remains at the preset resistance value.

[0223] The preset resistance value is the atomization resistance value when the e-cigarette is atomizing. This is the normal operating resistance value. Typically, an e-cigarette is set with an atomization temperature at the factory, which corresponds to the resistance value of a heating element. When the e-cigarette is working, the battery device outputs voltage to the heating element to make it work and monitors the resistance value of the heating element in real time. When the resistance value of the heating element reaches the resistance value corresponding to the preset atomization temperature, the output power is controlled to stabilize the resistance value of the heating element at that value, which is the aforementioned atomization resistance value. Of course, the atomization resistance value can also be calculated based on the atomization temperature or power set by the user. During the heating process of an electronic cigarette, if the time it takes for the resistance of the heating element to rise to the preset resistance value is less than the preset time, it indicates that the heating element is heating up too quickly due to dry burning. To protect the cartridge, heating is stopped at this time. If the time it takes for the resistance of the heating element to rise to the preset resistance value is greater than or equal to the preset time, it indicates that the heating element is working normally. At this time, the output power of the heating element is controlled to stabilize the resistance of the heating element at the preset resistance value. Stable resistance means that the deviation of the resistance of the heating element from the preset resistance value is within a small range.

[0224] In one embodiment, the control method for electronic cigarettes may further include the following steps:

[0225] The heating element is controlled to work according to the received preset operation signal to remove the residue on the heating element;

[0226] During the operation of the heating element, the rate of change of the heating element's resistance is obtained;

[0227] If the rate of change of resistance is less than the preset rate of change, the heating element will stop working.

[0228] If the resistance change rate is greater than or equal to the preset change rate, the heating element is controlled to work to remove the residue on the heating element.

[0229] The e-cigarette features a manual self-cleaning button at the bottom. Pressing this button generates a preset operation signal to activate the heating element, initiating self-cleaning. The preset resistance change rate refers to the rate of resistance change when the heating element is working to remove residue without a cartridge installed. During self-cleaning, if the cartridge is still inserted, the heating element's resistance change rate will be lower than the preset rate due to the presence of a significant amount of aerosol matrix. Continuing self-cleaning in this case could damage the cartridge, so the heating element stops working, halting self-cleaning. Conversely, if the resistance change rate is greater than or equal to the preset rate, it is considered that the heating element is not in contact with the aerosol matrix in the cartridge, allowing for residue cleaning, and the heating element continues to operate.

[0230] The present invention discloses a control method for an electronic cigarette, wherein the cartridge of the electronic cigarette stores an aerosol-forming matrix, and a heating element is provided on the battery device. The heating element is used to heat the aerosol-forming matrix in the cartridge when power is applied. When a separation signal indicating that the cartridge has been removed from the battery device is detected, the heating element is controlled to operate to remove residues from the heating element. In this way, the present invention can automatically remove residues from the heating element when the cartridge is removed from the battery device, thereby performing self-cleaning and improving the service life of the heating element.

[0231] Figure 28 This is a schematic diagram of the structure of an electronic cigarette according to an exemplary embodiment of the present invention. Figure 28 As shown, the present invention also provides an electronic cigarette, including a memory 310 and a processor 320. The memory 310 stores at least one program instruction, and the processor 320 loads and executes the at least one program instruction to implement the electronic cigarette control method described above.

[0235] For the specific steps and flow of the computer program instructions stored on the computer storage medium in this embodiment being executed by the processor, please refer to [reference needed]. Figures 1 to 27 The description of the illustrated embodiments will not be repeated here.

[0236] Please refer to Figure 29 This illustrates a flowchart of a method for controlling an electronic cigarette according to an embodiment of the present invention. Figure 29 As shown, the control method for this electronic cigarette may include:

[0237] Step 110: Check if the standby conditions for the electronic cigarette are met.

[0238] This step can be achieved in the following two ways:

[0239] The first method involves determining whether the e-cigarette has been operated. If the e-cigarette has not been operated for a predetermined time, then the standby conditions for the e-cigarette are considered met. The predetermined time can be set by the developers or customized by the user.

[0240] Specifically, determining whether an electronic cigarette has been operated can be achieved by: acquiring operation information of the electronic cigarette, including lighting information and movement indication information; and determining whether the electronic cigarette has been operated based on the operation information.

[0241] The lighting information refers to whether the electronic cigarette is lit, that is, whether the atomizing component inside the electronic cigarette is atomizing; the movement indication information includes at least one of the following: the acceleration information of the electronic cigarette, the liquid level information in the liquid reservoir of the electronic cigarette, and the flow information of the e-liquid in the liquid reservoir of the electronic cigarette.

[0242] Optionally, determining whether an electronic cigarette has been operated based on the cigarette lighting information can be implemented as follows: if no cigarette lighting signal is detected, determine that the electronic cigarette has not been operated for inhalation; or, if no vaporization operation is performed according to the cigarette lighting signal, determine that the electronic cigarette has not been operated for inhalation; or, if both a cigarette lighting signal and an inhalation signal are detected, determine that the electronic cigarette has been operated for inhalation, otherwise determine that the electronic cigarette has not been operated for inhalation.

[0243] The cigarette-lighting signal involved in this application can be a signal generated when the cigarette-lighting button on the electronic cigarette is operated. The cigarette-lighting signal can also be an airflow signal detected by a sensor component inside the electronic cigarette. The airway where the sensor component is located is connected to the mouthpiece of the electronic cigarette. When the user inhales through the mouthpiece of the electronic cigarette, since the sensor component is located in the airway connected to the mouthpiece, the sensor component can detect changes in airflow in the airway, such as changes in air pressure, changes in airflow velocity, etc. The sensor component can be a sensor for detecting airflow, such as an air pressure sensor, an airflow sensor, a pressure sensor, etc.

[0244] Optionally, when the cigarette lighting signal is not the airflow signal detected by the sensor components inside the electronic cigarette, the inhalation signal can be the airflow signal detected by the sensor components inside the electronic cigarette.

[0245] Optionally, the specific implementation of determining whether the electronic cigarette has been operated based on the movement indication information can be as follows: if it is determined from the movement indication information that the electronic cigarette is idle, then it is determined that the electronic cigarette has not been operated.

[0246] When a user holds and rotates or moves the electronic cigarette, the electronic cigarette generates acceleration, the liquid level in the reservoir agitates, and the e-liquid in the reservoir flows. In this application, the electronic cigarette can obtain movement indication information; based on this movement indication information, it can determine whether the electronic cigarette is stationary or being moved.

[0247] The determination of whether an e-cigarette is inactive based on the movement indication information can be achieved in any of the following ways: 1. If the acceleration of the e-cigarette is lower than or equal to a predetermined threshold, the e-cigarette is determined not to be operated; 2. If the change in the liquid level in the reservoir is lower than or equal to a predetermined threshold, the e-cigarette is determined not to be operated; 3. If the flow rate of the e-liquid in the reservoir is lower than or equal to a predetermined threshold, the e-cigarette is determined not to be operated. The predetermined threshold is usually set by the developers.

[0248] In this application, the liquid level can be detected by setting a liquid level detector in the liquid storage cavity, the acceleration of the electronic cigarette can be detected by a gyroscope or other acceleration detection device inside the electronic cigarette, and the flow velocity of the e-liquid in the liquid storage cavity can be detected by a flow velocity detection device inside the liquid storage cavity. This application does not specifically limit the height detection method, acceleration detection method, and e-liquid flow information detection method.

[0249] The second method involves detecting whether a standby command has been received. If a standby command is received, then the standby conditions for the e-cigarette are determined to be met. The standby command can be generated by the operation of the child lock button on the e-cigarette, or by being tapped on the e-cigarette. Other standby commands are also possible, but will not be elaborated upon in this implementation.

[0250] Optionally, the specific implementation of detecting whether a standby command has been received can be: acquiring tapping information from the electronic cigarette; and determining whether a standby command has been received based on the tapping information. Optionally, a 3D sensor can be installed inside the electronic cigarette, and the data detected by the 3D sensor can be used to determine whether the electronic cigarette has been tapped and tapping information has been obtained; when the tapping information of the electronic cigarette indicates that the electronic cigarette has been tapped continuously for a second predetermined number of times, it is determined that a tapping command has been received. The second predetermined number of times can be set by the developer or customized by the user.

[0251] Step 120: If the standby conditions of the electronic cigarette are met, control the electronic cigarette to enter standby mode.

[0252] Step 130: If a cigarette-lighting signal is detected when the electronic cigarette is in standby mode, the electronic cigarette stops controlling the atomizing component to perform atomization work according to the cigarette-lighting signal.

[0253] By controlling the e-cigarette to enter standby mode, the e-cigarette in standby mode stops controlling the atomizing component to atomize according to the lighting signal, thus temporarily disabling the e-cigarette's lighting function.

[0254] For example, after an e-cigarette user has been using the e-cigarette, if the e-cigarette is left to standby for a predetermined time of 1 minute, the e-cigarette will enter standby mode and stop vaporizing according to the lighting signal. At this time, if a child grabs the e-cigarette and accidentally touches the lighting button, the e-cigarette will not vaporize according to the lighting signal, thus preventing the child from accidentally inhaling the vapor.

[0255] In summary, the method provided by this invention detects whether the standby conditions of the electronic cigarette are met; if the standby conditions are met, the electronic cigarette is controlled to enter a standby state; if a cigarette-lighting signal is detected while the electronic cigarette is in standby state, the electronic cigarette stops controlling the atomizing component to perform atomization work according to the cigarette-lighting signal; this solves the problem in related technologies where children accidentally touch the cigarette-lighting button, and the atomized smoke is inhaled by the children, harming their physical and mental health; thus achieving the effect of increasing the child protection function of electronic cigarettes.

[0256] After the e-cigarette enters standby mode, the user can activate the e-cigarette's atomization function by generating an atomization wake-up signal. Specifically, if the e-cigarette detects an atomization wake-up signal while in standby mode, it will control the e-cigarette to enter working mode; if the e-cigarette detects a cigarette lighting signal while in working mode, it will control the atomization component to perform atomization work according to the cigarette lighting signal.

[0257] In one example, an e-cigarette user can trigger the e-cigarette to enter working mode by removing and reinstalling a predetermined component. Specifically, if, after detecting the removal of a predetermined component from the e-cigarette, any predetermined component is then detected being installed into the e-cigarette body, a vaporization wake-up signal is determined to have been detected. This predetermined component is either an atomizer or a cartridge.

[0258] In one example, a probe or button switch is provided on the mounting base. When a predetermined component is installed on the mounting base, the predetermined component abuts against the probe or presses the button switch. When the electronic cigarette detects an operation signal generated by the probe being abutted or the button switch being pressed, it determines that the predetermined component has been installed on the body of the electronic cigarette.

[0259] In another example, a heating element is provided within a predetermined component, which is connected to a load access circuit within the electronic cigarette body when the predetermined component is installed to the mounting base; the electronic cigarette determines that the predetermined component has been installed to the electronic cigarette body when it detects that a load is connected to the load access circuit.

[0260] In another example, a magnetic element is provided within the predetermined component, and a Hall switch is provided at the mounting base. When the predetermined component is installed onto the mounting base, the Hall switch detects the magnetic element; the electronic cigarette detects whether the predetermined component is installed onto the mounting base via the Hall switch. In actual implementation, the magnetic element can be a magnetic ring or a circular magnetic sheet located at the bottom or end of the cartridge.

[0261] Optionally, the electronic cigarette body has a receiving cavity for a predetermined component, and a mounting base for the predetermined component is disposed within the receiving cavity. The electronic cigarette user can install the predetermined component onto the electronic cigarette body by inserting it into the receiving cavity. Alternatively, the electronic cigarette can be separated from the electronic cigarette body by pulling the predetermined component out of the receiving cavity. In this embodiment, the electronic cigarette user can trigger the electronic cigarette to enter working mode by pulling the predetermined component out of the receiving cavity and then inserting it again.

[0262] In another embodiment, the e-cigarette user can trigger the e-cigarette to enter standby mode by removing a predetermined component from the receiving cavity; and then trigger the e-cigarette to enter working mode by inserting the predetermined component into the receiving cavity. Specifically, this can be implemented as follows: when the predetermined component is detected to be separated from the e-cigarette body, a standby command is determined to be received, and the e-cigarette is controlled to enter standby mode according to the standby command; when the predetermined component is detected to be installed into the e-cigarette body, an atomization wake-up signal is determined to be detected, and the e-cigarette is controlled to enter working mode according to the atomization wake-up signal.

[0263] In another example, when standby conditions are met, the e-cigarette is controlled to enter a standby state, and a predetermined component, such as an atomizer or cartridge, is separated from the e-cigarette body. In this method, the e-cigarette user can then reinstall the predetermined component into the e-cigarette body, for example, by inserting it into a mounting base within a corresponding receiving cavity. When the e-cigarette detects that the predetermined component has been installed into its body, it enters a working state; and if a cigarette-lighting signal is detected, the atomizing assembly is controlled to perform atomization.

[0264] Taking a cartridge as an example, the electronic cigarette body is provided with a cartridge receiving cavity, and a cartridge mounting base is provided inside the receiving cavity; a pusher can be provided on the mounting base, and when the electronic cigarette meets the standby conditions, the pusher is driven to push the cartridge, so that the cartridge is detached from the mounting base.

[0265] In another example, when standby conditions are met, the electronic cigarette is controlled to enter a standby state, and a predetermined component within the electronic cigarette is controlled to rotate around its central axis, causing a first component within the predetermined component to separate from or move away from a second component on the electronic cigarette body. The predetermined component is an atomizer or a cartridge; when the first component is separated from or moves away from the second component, the electronic cigarette lacks atomization capability. In this method, the electronic cigarette user can then operate the predetermined component to rotate around its central axis to reset it. When the electronic cigarette detects the predetermined component resetting, it determines that an atomization wake-up signal has been detected.

[0266] In another example, the e-cigarette user can trigger the e-cigarette to enter the working state by rotating and resetting a predetermined component. Specifically, after the e-cigarette detects that the first component has separated from or moved away from the second component on the e-cigarette body, if it detects that the predetermined component has been rotated to a predetermined position (i.e., reset), it determines that an atomization wake-up signal has been detected, and the e-cigarette has atomization capability when the predetermined component is rotated to the predetermined position.

[0267] Optionally, the e-cigarette user can trigger the e-cigarette to enter working state by rotating a predetermined component. Specifically, when the e-cigarette is in standby mode, it detects whether a predetermined component inside the e-cigarette has been rotated; the predetermined component is an atomizer or cartridge. If the predetermined component is detected to have been rotated to a predetermined position, an atomization wake-up signal is detected. Optionally, the e-cigarette determines that it has received a standby command and enters standby mode when it detects that the first component has separated from or moved away from the second component on the e-cigarette body, allowing the user to trigger the e-cigarette to enter standby mode by rotating the predetermined component.

[0268] Optionally, the first and second components within the electronic cigarette can be configured in the following ways:

[0269] In the first configuration, the first component is an electrode on the cartridge, and the second component is an electrode on the electronic cigarette body. When the first and second components are connected, the battery component inside the electronic cigarette body can supply power to the atomizing component (e.g., a heating element) within a predetermined part through the first and second components to perform atomization. When the electronic cigarette meets standby conditions, the predetermined part can be controlled to rotate around its central axis, causing the electrode on the predetermined part to separate from the electrode on the electronic cigarette body. This allows the electronic cigarette to stop atomizing based on a cigarette-lighting signal when it detects such a signal.

[0270] The second type involves a liquid storage chamber within a predetermined component as the first component, and a heating element and a liquid guiding element on the electronic cigarette body, with the liquid guiding element being the second component. Both ends of the liquid guiding element can extend into the liquid storage chamber. When both ends of the liquid guiding element extend into the liquid storage chamber, the liquid guiding element can absorb the e-liquid in the liquid storage chamber. When the electronic cigarette controls the heating element to heat up according to the cigarette lighting signal, it can atomize the e-liquid on the liquid guiding element. When the electronic cigarette meets the standby conditions, it can control the predetermined component to rotate around the central axis of the predetermined component, causing the liquid guiding element to separate from the liquid storage chamber and stop the liquid guiding element from continuing to absorb e-liquid, so that the electronic cigarette stops atomizing according to the cigarette lighting signal when it detects the cigarette lighting signal.

[0271] The third type has a first component that is a liquid-absorbing element within a predetermined component, used to draw e-liquid from the storage chamber of the predetermined component. The second component is a heating element. When the liquid-absorbing element and the heating element are close to each other, the liquid-absorbing element draws e-liquid from the storage chamber, and the heating element heats up and atomizes the e-liquid on the liquid-absorbing element. When the electronic cigarette meets the standby conditions, it can control the predetermined component to rotate around the central axis of the predetermined component, so that the liquid-absorbing element is moved away from the heating element, so as to avoid the heating element atomizing the e-liquid on the liquid-absorbing element when it heats up, so that the electronic cigarette stops atomizing according to the cigarette-lighting signal when it detects the cigarette-lighting signal.

[0272] Optionally, a magnetic element may be provided on the predetermined component, and a Hall switch may be provided on the mounting base. The electronic cigarette user can rotate the predetermined component to keep the magnetic element at a preset distance or away from the Hall switch. When the predetermined component is rotated to the reset position, the Hall switch can detect the magnetic element, and when the predetermined component leaves the reset position, the Hall switch cannot detect the magnetic element. The electronic cigarette detects whether the predetermined component has been rotated to the reset position through the Hall switch. In actual implementation, other methods can also be used to determine whether the predetermined component has been rotated to the reset position, which will not be described in detail in this embodiment.

[0273] It should be noted that: in this application, the first component inside the predetermined component is separated from or moved away from the second component on the electronic cigarette body by controlling the predetermined component to rotate around the central axis of the predetermined component; in actual implementation, the first component and the second component can also be separated or moved away by other means, such as driving the first component to move and change position, or driving the second component to move and change position, which will not be described in detail in this embodiment.

[0274] When the e-cigarette is in standby mode, the user can still activate the atomization function using any of the following wake-up methods:

[0275] The first method involves the e-cigarette user tapping the e-cigarette to activate its vaporization function. Specifically, this can be achieved by: acquiring movement indication information of the e-cigarette when it is in standby mode; this movement indication information includes at least one of the following: acceleration information of the e-cigarette, liquid level information in the e-cigarette's reservoir, and e-liquid flow information in the e-cigarette's reservoir; determining the tapping information of the e-cigarette based on this movement indication information; and if the tapping information meets a first wake-up condition, then determining that a vaporization wake-up signal has been detected.

[0276] The first wake-up condition can be set by the developer or customized by the user; for example, the first wake-up condition can be that the electronic cigarette is tapped a first predetermined number of times. The first predetermined number of times can be set by the developer or customized by the user. This embodiment does not specifically limit the first wake-up condition.

[0277] In practical implementation, an electronic cigarette can be equipped with a 3D sensor. The data detected by this 3D sensor can be used to determine whether the electronic cigarette is in a static state or has been tapped. For example, when an electronic cigarette is tapped, it will vibrate. The 3D sensor can be used to determine whether the electronic cigarette is vibrating, and if it is, it can be determined that the electronic cigarette has been tapped.

[0278] The second method involves the e-cigarette user activating the atomization function by pressing the activation button on the e-cigarette. Specifically, this can be achieved by: acquiring the operation information generated by pressing the activation button when the e-cigarette is in standby mode; and confirming that the atomization wake-up signal has been detected when the operation information meets the second wake-up condition.

[0279] The second wake-up condition can be set by the system developers or customized by the user. For example, the second wake-up condition can be that the wake-up button is pressed multiple times in a row, or the wake-up button is pressed and held for a preset first duration. This embodiment does not specifically limit the second wake-up condition.

[0280] The third method involves the e-cigarette user entering their fingerprint at the fingerprint input device of the e-cigarette to activate the e-cigarette's atomization function. Specifically, this can be achieved by: acquiring the fingerprint collected by the fingerprint input device when the e-cigarette is in standby mode; comparing the collected fingerprint with a preset fingerprint; and confirming that an atomization wake-up signal has been received when the collected fingerprint matches the preset fingerprint, and controlling the atomization component to perform atomization work according to the cigarette lighting signal.

[0281] The fourth type is an electronic cigarette equipped with a facial recognition device, which allows users to activate the vaporization function of the electronic cigarette by performing facial recognition.

[0282] In one example, the specific implementation can be as follows: when the electronic cigarette is in standby mode, a facial recognition device is used to collect a facial image; when the facial image matches a preset facial image, it is determined that a vaporization wake-up signal has been received, and the vaporization component is controlled to perform vaporization work according to the cigarette lighting signal.

[0283] In another example, when the e-cigarette is in standby mode, a facial recognition device is used to capture a facial image; the facial features in the image are used to determine whether the user is a child; if the user is not a child, a vaporization wake-up signal is received, and the vaporization component is controlled to perform vaporization based on the cigarette lighting signal.

[0284] In another example, when the e-cigarette is in standby mode, a facial recognition device captures a facial image; the facial features in the image are identified to determine the user's age; if the user's age is higher than or equal to a preset age, it is determined that a vaporization wake-up signal has been received, and the vaporization component is controlled to perform vaporization based on the cigarette lighting signal. The preset age can be set by the developers or customized by the user; for example, the preset age could be 18 years old.

[0285] The fifth method involves the e-cigarette user pressing a pressure button or pressure sensor to activate the e-cigarette's atomization function. Specifically, when the e-cigarette is in standby mode, it acquires the pressure value detected by the pressure button or pressure sensor. When the detected pressure value reaches a preset pressure value, it confirms receipt of an atomization wake-up signal and controls the atomization component to perform atomization based on the lighting signal. The preset pressure value can be set by the developers or customized by the user; for example, the developers can set the preset pressure value to be higher than the maximum output force for a child.

[0286] The sixth method involves the e-cigarette user speaking a preset voice command to activate the e-cigarette's vaporization function. Specifically, this can be achieved by: activating a voice acquisition device when the e-cigarette is in standby mode; acquiring voice information collected by the voice acquisition device; and if the voice information contains a preset voice command, confirming that a vaporization activation signal has been received, and controlling the vaporization component to perform vaporization based on the cigarette-lighting signal. The preset voice command can be set by the developer or customized by the user. For example, the developer can set the voice command to any of the following: power on, vaporize, start, etc. This embodiment does not specifically limit this.

[0287] The seventh method involves activating the e-cigarette's vaporization function when the user approaches the e-cigarette with a terminal device linked to it. Specifically, when the e-cigarette is in standby mode, it uses wireless communication technology to search for terminal devices within a predetermined range (the range supported by this technology). If a terminal device linked to the e-cigarette is detected or a wireless connection is established, a vaporization wake-up signal is received, and the vaporization component is controlled to vaporize according to the lighting signal. Alternatively, the terminal device linked to the e-cigarette sends a vaporization wake-up signal to the e-cigarette via wireless or wired communication technology. When the e-cigarette receives the signal, it controls the vaporization component to vaporize according to the lighting signal.

[0288] Wireless communication technologies can include any of the following: Bluetooth, NFC (Near Field Communication), infrared, etc. Wired communication can be achieved through a USB data cable connection.

[0289] The eighth type involves an iris recognition device installed on the e-cigarette. The user performs iris recognition to activate the e-cigarette's vaporization function. Specifically, when the e-cigarette is in standby mode, the iris recognition device captures an iris image; when this iris image matches a preset iris image, a vaporization wake-up signal is received, and the vaporization component is controlled to perform vaporization based on the cigarette-lighting signal.

[0290] The ninth method involves e-cigarette users activating the e-cigarette's atomization function by entering a activation password. Specifically, this can be achieved by: obtaining the password entered by the user; if the password entered by the user matches the preset activation password, then confirming that an atomization wake-up signal has been received, and controlling the atomization component to perform atomization work according to the cigarette lighting signal.

[0291] The tenth method involves e-cigarette users activating the atomization function of the e-cigarette by inputting an unlock gesture. Specifically, this can be achieved by: acquiring the unlock gesture input by the user; if the unlock gesture input by the user matches the preset unlock gesture, then confirming that an atomization wake-up signal has been received, and controlling the atomization component to perform atomization work according to the cigarette lighting signal.

[0292] Eleventh, an e-cigarette user can activate the e-cigarette's atomization function by shaking it. Specifically, this can be achieved by: acquiring the e-cigarette's shaking indication information, which includes at least one of the following: the e-cigarette's acceleration information, the liquid level information in the e-cigarette's reservoir, and the e-liquid flow information in the e-cigarette's reservoir; determining the e-cigarette's shaking frequency based on the shaking indication information; and if the e-cigarette's shaking frequency reaches a preset frequency threshold, determining that an atomization wake-up signal has been received, and controlling the atomization component to perform atomization work according to the cigarette lighting signal.

[0293] The twelfth method is that the e-cigarette user can use an external device (e.g., USB) to activate the e-cigarette's atomization function. Specifically, if the e-cigarette has not been operated for a predetermined time and a connection to an external device is detected, it is determined that an atomization wake-up signal has been received, and the atomization component is controlled to perform atomization work according to the cigarette lighting signal.

[0294] The thirteenth method involves the e-cigarette user forcefully inhaling to activate the e-cigarette's atomization function. Specifically, the e-cigarette has an independent airway connected to the mouthpiece but isolated from the atomization chamber. This independent airway is equipped with a pressure detection device. When the pressure detected by the device reaches a preset pressure threshold, an atomization activation signal is received, and the atomization component is controlled to perform atomization based on the cigarette lighting signal.

[0295] The preset air pressure threshold can be set by the developers or customized by the users. The preset air pressure threshold can be the air pressure value that is difficult to reach in the independent airway when a child is inhaling.

[0296] The fourteenth type is that after the e-cigarette's atomization function is turned off, the e-cigarette can restart the atomization function at a set time. Specifically, the timing can be as follows: when the e-cigarette has not been operated for a predetermined time, the timing starts; when the preset restart time is reached, the atomization wake-up signal is received, and the atomization component is controlled to perform atomization work according to the cigarette lighting signal.

[0297] Optionally, if no operation of the electronic cigarette is detected within a preset second time period after the electronic cigarette starts its atomization function, the electronic cigarette is controlled to stop controlling the atomization component to perform atomization work according to the cigarette lighting signal. When the atomization function is off for a preset restart time period, an atomization wake-up signal is confirmed to be received, and the atomization component is controlled to perform atomization work according to the cigarette lighting signal.

[0298] The fifteenth method involves electronic cigarettes recognizing user body shape information, including at least one of height, weight, etc.; determining whether the user is a child based on this body shape information; and if the user is not a child, confirming that a vaporization wake-up signal has been received, and controlling the vaporization component to perform vaporization work based on the cigarette lighting signal.

[0299] The sixteenth method involves the e-cigarette user removing and reinstalling a predetermined component from the e-cigarette to activate its atomization function. Specifically, when the e-cigarette is detected to have switched from a state without the predetermined component to a state with the predetermined component installed, an atomization wake-up signal is received, and the atomization component is controlled to perform atomization based on the cigarette lighting signal.

[0300] The implementation of detecting the switching of the electronic cigarette from a state without the predetermined component to a state with the predetermined component installed can be referred to the implementation of detecting the predetermined component being installed on the electronic cigarette body in the above content, and will not be repeated here.

[0301] Optionally, when a vapor wake-up signal is detected, a vapor wake-up prompt message is displayed. This prompt message can be displayed in any of the following ways: text prompt, voice prompt, sound prompt, indicator light prompt, etc.

[0302] Optionally, if the e-cigarette meets the standby conditions, the e-cigarette is controlled to enter the standby state, and the lock installed on the e-cigarette is locked; thereafter, the user can unlock the e-cigarette with a key to start the atomization function. Correspondingly, if the e-cigarette detects a cigarette-lighting signal when it detects that the lock is opened, it controls the atomization component to perform atomization.

[0303] In practice, e-cigarette users can lock the e-cigarette with a key to trigger it to enter standby mode. Specifically, when the e-cigarette detects that the lock is closed, it determines that it has received a standby command and enters standby mode according to the command.

[0304] Optionally, if the e-cigarette meets the standby conditions, the e-cigarette is controlled to enter the standby state, and the control knob is rotated from the initial position to a predetermined angle in the first direction; the user can operate the knob to rotate the predetermined angle in the second direction to activate the e-cigarette's atomization function; correspondingly, when the e-cigarette detects that the knob has been rotated to the initial position, it determines that an atomization wake-up signal has been detected.

[0305] When the first direction is clockwise, the second direction is counterclockwise; when the first direction is counterclockwise, the second direction is clockwise. The predetermined angle is usually set by the developers. Electronic cigarettes display instructions on the knob to indicate whether to rotate the knob in the second direction, such as arrows.

[0306] In practice, e-cigarette users can rotate the knob from the initial position to a preset position by a predetermined angle in the first direction to trigger the e-cigarette to enter standby mode. Specifically, when the e-cigarette detects that the knob has been rotated to the preset position, it determines that it has received a standby command and enters standby mode according to the standby command.

[0307] Optionally, when the e-cigarette is in working mode, the user can also trigger the e-cigarette to enter standby mode through any of the following standby operation methods:

[0308] The first method involves the e-cigarette user pressing the child lock button on the e-cigarette to trigger the e-cigarette to enter standby mode. Specifically, this can be achieved by: when the e-cigarette is in working mode, detecting the operation information generated by pressing the child lock button; and when the operation information meets the standby conditions, determining that the atomization wake-up signal has been detected.

[0309] The standby conditions can be set by the system developers or customized by the user. For example, the standby conditions can be that the child lock button is pressed multiple times in a row, or that the child lock button is pressed and held for a preset third time. This embodiment does not specifically limit the standby conditions.

[0310] The second method involves the e-cigarette user entering their fingerprint at the fingerprint input device of the e-cigarette, triggering the e-cigarette to enter working mode.

[0311] The third method involves installing a facial recognition device on the electronic cigarette to capture facial images; determining whether the user is a child based on the facial features in the image; and if the user is identified as a child, then receiving a standby command.

[0312] Fourthly, when the e-cigarette is in standby mode, a facial recognition device is used to capture a facial image; the facial features in the image are identified to determine the user's age; if the user's age is lower than a preset age, a standby command is received. The preset age can be set by the developers or customized by the user; for example, the preset age could be 18 years old.

[0313] The fifth method involves the e-cigarette user pressing a pressure button or pressure sensor to trigger the e-cigarette to enter standby mode. Specifically, this can be achieved by: acquiring the pressure value detected by the pressure button or pressure sensor when the e-cigarette is in standby mode; and confirming receipt of a standby command when the detected pressure value reaches a preset pressure value. The preset pressure value can be set by the developers or customized by the user.

[0314] The sixth method involves the e-cigarette user speaking a preset voice command to the e-cigarette to indicate that it is in standby mode, thus triggering the e-cigarette to enter standby mode. Specifically, this can be achieved by: activating a voice acquisition device when the e-cigarette is in standby mode; acquiring voice information collected by the voice acquisition device; and confirming that a standby command has been received if the voice information contains a preset voice command. The preset voice command can be set by the developer or customized by the user. For example, the developer can set the voice command to any of the following: standby, hibernation, or shutdown. This embodiment does not specifically limit this.

[0315] The seventh method involves the electronic cigarette receiving a standby command when it exceeds a preset distance from the bound terminal device. This preset distance can be set by the system developers or customized by the user; this embodiment does not impose specific limitations on it.

[0316] The eighth method involves an iris recognition device installed on the e-cigarette. The user performs iris recognition on the e-cigarette to trigger it into standby mode. Specifically, this can be implemented as follows: when the e-cigarette is in standby mode, the iris recognition device captures an iris image; when this iris image matches a preset iris image, a standby command is received.

[0317] The ninth method involves the e-cigarette user triggering the e-cigarette to enter standby mode by entering a shutdown password. Specifically, this can be achieved by: obtaining the password entered by the user; if the password entered by the user matches the preset shutdown password, then it is confirmed that a standby command has been received.

[0318] The tenth method is that e-cigarette users can trigger the e-cigarette to enter standby mode by inputting a standby gesture. Specifically, this can be achieved by: obtaining the standby gesture input by the user; if the standby gesture input by the user matches the preset standby gesture, then it is determined that a standby command has been received.

[0319] Eleventh, an e-cigarette user can trigger the e-cigarette to enter standby mode by shaking it. Specifically, this can be achieved by: acquiring the shaking indication information of the e-cigarette, which includes at least one of the following: acceleration information of the e-cigarette, liquid level information in the liquid reservoir of the e-cigarette, and e-liquid flow information in the liquid reservoir of the e-cigarette; determining the shaking frequency of the e-cigarette based on the shaking indication information; and determining that a standby command has been received if the shaking frequency of the e-cigarette reaches a preset frequency threshold.

[0320] The twelfth method involves allowing e-cigarette users to trigger the e-cigarette into standby mode using an external device. Specifically, if a connection between the e-cigarette and an external device is detected, a standby command is confirmed. Alternatively, when the e-cigarette is connected to an external device via wired or wireless means, the user can send a standby command to the e-cigarette via the external device, and the e-cigarette will enter standby mode upon receiving the command.

[0321] The thirteenth method is for the e-cigarette user to forcefully inhale to trigger the e-cigarette to enter standby mode. Specifically, the e-cigarette is equipped with an independent airway that is connected to the mouthpiece but isolated from the atomization chamber. The independent airway is equipped with an air pressure detection device.
