[0170] Now, the present invention will be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, so it only shows the components related to the present invention.

[0171] Please refer to Figure 1 , Figure 2 , the present invention provides an e-cigarette, which includes a cartridge 10 and a battery device 20 that cooperates with the cartridge 10. The cartridge 10 and the battery device 20 are detachably connected. The e-cigarette further includes an atomizing device. When in use, the battery device 20 supplies power, and the atomizing device atomizes the aerosol stored in the cartridge 10 under the electric driving action of the battery device 20 to form a matrix. The aerosol matrix forms smoke under the atomizing action, and the smoke is 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 provided on the cartridge 10, can be provided on the battery device 20, or can be independently provided relative to the cartridge 10 and the battery device 20. When the atomizing device is provided on the battery device 20, or is independently provided relative to the cartridge 10 and the battery device 20, the user does not need to deal with the atomizing device when replacing the cartridge 10, which can reduce the user's replacement cost. The aerosol matrix can be e-liquid, tobacco shreds, or tobacco paste. When the types of the aerosol matrix are different, the structure of the cartridge 10 is also different. For example, when the aerosol matrix is tobacco shreds, the cartridge 10 can be set to a structure similar to that of a regular cigarette. In this embodiment, the aerosol matrix is taken as an example of e-liquid.

[0172] Please refer to Figure 4 、 Figure 7 and Figure 8 As shown, the cartridge 10 includes a seal 14, a mouthpiece 13 provided with a smoke outlet 131, a cartridge housing 16, a gasket 162, a liquid absorber 17, a liquid absorber bracket 18, and a base 15. The mouthpiece 13 is installed at the upper end of the cartridge housing 16. The gasket 162 is provided at the upper end of the cartridge housing 16 and located between the mouthpiece 13 and the cartridge housing 16. A part of the seal 14 is inserted into the interior of the cartridge housing 16 through the mouthpiece 13 and the gasket 162 in sequence, and another part of the seal 14 is exposed outside the cartridge 10. The liquid absorber 17 and the liquid absorber bracket 18 are provided inside the lower end of the cartridge housing 16, and the base 15 is connected to the lower end of the cartridge housing 16. The base 15 is provided with an atomization chamber 151, an air inlet 152, and a mating portion 153. The air inlet 152 and the mating portion 153 are located on opposite sides of the atomization chamber 151 respectively. When the cartridge 10 is installed on the battery device 20, the mating portion 153 and the battery device 20 form a specific mating structure for detecting whether the cartridge 10 is installed on the battery device 20 and whether the cartridge 10 is removed from the battery device 20.

[0173] The cartridge shell 16 is roughly a hollow cylindrical structure with two ends connected, and the inner cavity of the cartridge shell 16 forms a liquid storage chamber 19 for storing smoke liquid. The volume of the liquid storage chamber 19 is 0.5-3ml. If the volume of the liquid storage chamber 19 is too small, the amount of smoke liquid stored cannot meet the user's suction needs. If the volume of the liquid storage chamber 19 is too large, the amount of smoke liquid stored is too large, resulting in the user may not be able to use it up on the same day. When the volume of the liquid storage chamber 19 is 0.5-3ml, it can just meet the user's suction needs. An airflow channel 165 is opened in the wall of one side of the cartridge shell 16 along the axial direction of the cartridge shell 16. The liquid storage chamber 19 and the airflow channel 165 are both opened 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, the upper opening of the airflow channel 165 is connected to the smoke outlet 131 of the cigarette holder 13, and 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, and the sealing gasket 162 is provided with an operating portion perforation 163 for penetrating the sealing member 14. The lower opening of the liquid storage chamber 19 constitutes a liquid outlet 191, and the liquid outlet 191 is used to connect the liquid storage chamber 19 with the liquid absorption member 17. The lower end of the cigarette cartridge housing 16 extends downward along the axial direction of the cigarette cartridge housing 16 to form a receiving portion (not shown in the figure). The liquid absorption member 17 is fixedly installed on the outside of the liquid outlet 191 and is located in the receiving portion through the liquid absorption member bracket 18, and the liquid absorption 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 cigarette cartridge 10, through the mouthpiece 13, the operating part perforation 163 of the sealing gasket 162, and is inserted into the liquid storage chamber 19 and blocks the liquid outlet 191, so that the liquid storage chamber 19 is sealed, so that the cigarette cartridge 10 will not leak the smoke liquid before use, which is convenient for storage and transportation, and the smoke liquid in the liquid storage chamber 19 will not deteriorate due to contact with the outside air. When the electronic cigarette needs to be used, the user can operate the seal 14, remove the seal 14 from the liquid outlet 191, so that the liquid outlet 191 is opened, and the smoke liquid in the liquid storage chamber 19 can contact the liquid absorbing member 17 through the liquid outlet 191 and then be absorbed by the liquid absorbing member 17.

[0174] In a specific embodiment, the liquid absorbent holder 18 is generally a hollow box-shaped structure with through holes at its upper and lower ends, and the liquid absorbent 17 is installed inside the cavity of the liquid absorbent holder 18. A plurality of bendable portions 181 are provided on the side wall of the liquid absorbent holder 18 around the upper through hole of the liquid absorbent holder 18. During installation, the liquid absorbent 17 is placed in the cavity of the liquid absorbent holder 18 so that the lower surface of the liquid absorbent 17 is in contact with the bottom wall of the liquid absorbent holder 18. Then, the bendable portions 181 are bent at a certain angle and a downward pressure is applied so that the bendable portions 181 are in contact with the upper surface of the liquid absorbent 17, thereby fixing the liquid absorbent 17 on the liquid absorbent holder 18. The operation is simple and convenient, and the automation of the installation of the liquid absorbent 17 can be realized. In this embodiment, the liquid absorbent 17 is cotton. It can be understood that in other embodiments not shown, the liquid absorbent 17 can also be an element with liquid absorption ability such as a fiber rope, a porous ceramic or a porous graphite, etc., which is not limited here.

[0175] Please further combine Figure 4 , Figure 7 and Figure 8, in this embodiment, the seal 14 includes an operation part 141 and a sealing part (not shown in the figure). One end of the operation part 141 extends to the outside of the cartridge 10 and can be operated by the user. The other end of the operation part 141 passes through the operation part perforation 163 and extends into the liquid storage cavity 19. The part of the operation part 141 located in the operation part perforation 163 seals the operation part perforation 163 to prevent the leakage of the e-liquid. The sealing part includes a first sealing part 142 and a second sealing part 143 which are connected to each other. One end of the first sealing part 142 is connected to one end of the operation part 141 located in the liquid storage cavity 19. The other end of the first sealing part 142 is connected to the second sealing part 143. And there is a transverse notch 145 at the connection between the first sealing part 142 and the operation part 141. The second sealing part 143 is used to seal the liquid outlet 191. When the operation part 141 moves outward along the operation part perforation 163 under the action of an external force, it drives the first sealing part 142 to move upward along the axial direction of the cartridge 10, and the first sealing part 142 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 aperture of the operation part perforation 163. When the operation part 141 is continuously pulled upward along the axial direction of the cartridge 10 until the second sealing part 143 abuts against the lower end surface of the sealing gasket 162, the seal 14 cannot move upward continuously. The first sealing part 142 is inserted into the operation part perforation 163 to seal the operation part perforation 163. Since there is a transverse notch 145 at the connection between the first sealing part 142 and the operation part 141, the operation part 141 and the first sealing part 142 can be disconnected under the action of an external force, so that the operation part 141 can be taken out after being separated from the first sealing part 142, and the first sealing part 142 seals the operation part perforation 163 without damaging the sealing performance at the upper end of the liquid storage cavity 19. In addition, the through hole on the mouthpiece 13 for inserting the seal 14 serves as the smoke outlet 131 after the operation part 141 is taken out. In this embodiment, a sealing strip 1421 protrudes radially outward along the outer wall of the first sealing part 142. The sealing strip 1421 is in close fit with the hole wall of the operation part perforation 163, improving the sealing performance of the liquid storage cavity 19. The movement stroke of the seal 14 (the movement distance of the second sealing part 143 from the liquid outlet 191 to the second sealing part 143 abutting against the lower end surface of the sealing gasket 162) is 5 - 50 mm. In a specific embodiment, the movement stroke of the seal 14 is 10 - 15 mm. If the movement stroke is too short, it indicates that the axial length of the liquid storage cavity 19 is too short. Thus, the volume of the liquid storage cavity 19 may be too small. If the movement stroke is too long, it will be inconvenient for the user to operate.

[0176] In addition, during the process of pulling the seal 14, the seal 14 deforms under the pulling force, creating a gap between the operating part 141 and the hole wall of the operating part perforation 163. External air can enter the liquid storage cavity 19 through the gap, facilitating the liquid in the liquid storage cavity 19 to flow out from the liquid outlet 191 and come into contact with the liquid absorbent member 17, which is then adsorbed by the liquid absorbent member 17. Otherwise, a negative pressure will be formed in the liquid storage cavity 19, which is not conducive to the outflow of the liquid. At the same time, the liquid absorbent member 17 is located between the upper opening of the atomization cavity 151 and the liquid outlet 191. Since the liquid absorbent member 17 is arranged directly below the liquid outlet 191, when the liquid outlet 191 is opened, the liquid in the liquid storage cavity 191 can be adsorbed by the liquid absorbent member 17 as soon as it flows out from the liquid outlet 191, shortening the flow distance of the liquid. In actual use, the size of the liquid outlet 191 can be set slightly larger as long as it matches the size of the liquid absorbent member 17. Thus, the liquid can be quickly adsorbed by the liquid absorbent member 17, shortening the waiting time for the liquid absorbent member 17 to adsorb the liquid after the user removes the operating part 141, and facilitating the user to quickly use the electronic cigarette.

[0177] In this embodiment, the atomizing device is disposed on the battery device 20. The atomizing device is a resistance heating device. Specifically, the atomizing device is 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 installed on the battery device 20, the heating element 21 disposed on the battery device 20 extends into the atomizing chamber 151 from the lower opening of the atomizing chamber 151 and contacts the liquid absorbing member 17 or maintains a preset distance from the liquid absorbing member 17. The heating element 21 can generate heat under the action of electric drive to heat the e-liquid on the liquid absorbing member 17, and the e-liquid is heated to form a mist. When the user uses it, the mist generated by atomizing the e-liquid in the atomizing chamber 151 flows out through the air flow channel 165 and the smoke outlet 131. When the e-liquid in the liquid storage chamber 19 is exhausted, the user can replace the new cartridge 10. Since the heating element 21 is disposed 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. In addition, the diameter of the lower opening of the air flow channel 165 is larger than the diameter of the upper opening of the air flow channel 165, so that the suction pressure at the lower opening of the air flow channel 165 is smaller, preventing large particle e-liquid from being sucked out. In addition, the channel wall at the lower end of the air flow channel 165 is arranged as an arc surface, making the connection smoother, with less obstruction to the mist and not easily generating condensate. Specifically, one side wall of the liquid storage chamber 19 and one side wall of the air flow channel 165 are the same wall body (not shown in the figure). The lower end of the wall body and the other walls of the liquid storage chamber 19 enclose to form the liquid outlet 191. The upper end of the wall body and the other channel walls of the air flow channel 165 enclose to form the upper opening of the air flow channel 165. The lower end of the wall body and the other channel walls of the air flow channel 165 enclose to form the lower opening of the air flow channel 165. The lower end of the wall body bends towards the liquid storage chamber 19, so that the diameter of the upper opening of the air flow channel 165 is smaller than the diameter of the lower opening of the air flow channel 165. At the same time, the diameter of the liquid outlet 191 is relatively small. Specifically, the lower end of the liquid storage chamber 19 contracts inward to prevent the e-liquid in the liquid storage chamber 19 from flowing out too fast through the liquid outlet 191.

[0178] In addition, the electronic cigarette of the present invention adopts a separation structure. Specifically, before using the electronic cigarette, the e-liquid in the liquid storage chamber 19 is separated from the liquid absorption member 17 through the separation structure, so that the e-liquid is kept in the liquid storage chamber 19. When in use, the liquid storage chamber 19 is opened, so that the e-liquid in the liquid storage chamber 19 flows onto the liquid absorption member 17 and is then adsorbed by the liquid absorption member 17. In this way, it is convenient for the storage and transportation of the cartridge 10. Moreover, it can effectively prevent the situation that the liquid absorption member 17 adsorbs some e-liquid before contacting the heating member 21, which may cause the heating member 21 to squeeze the liquid absorption member 17 when the cartridge 10 is installed and squeeze out the e-liquid adsorbed on the liquid absorption member 17, avoiding e-liquid leakage. It can be understood that when the liquid absorption member 17 is made of a hard material such as porous ceramic, a separation structure may not be provided between the liquid storage chamber 19 and the liquid absorption member 17, and the liquid absorption member 17 will not deform under the extrusion of the heating member 21. Therefore, the e-liquid on the liquid absorption member 17 will not be squeezed out. It can be understood that in other embodiments not shown, in addition to using the seal 14 as the separation structure, other separation structures may also be used, for example, a pierceable sealing film or a movable sealing plate, and the liquid storage chamber 19 is opened by piercing the sealing film or the movable sealing plate.

[0179] Please refer to again Figure 7 、 Figure 8 , the base 15 is located in the receiving portion, and the base 15 is snap-connected with the cartridge housing 16. In order to ensure the sealing performance of the base 15, a base seal 161 is also provided between the base 15 and the cartridge housing 16. The base seal 161 is sleeved on the outside of the upper end of the base 15. An installation portion 166 is convexly provided on the upper end surface of the base seal 161 corresponding to the upper end opening of the atomization chamber 151. The lower end of the installation portion 166 is open. The liquid absorption member 17 is installed on the liquid absorption member bracket 18. The liquid absorption member 17 together with the liquid absorption member bracket 18 is received in the installation portion 166 through the lower end opening of the installation portion 166. A liquid passing hole 167 communicating with the liquid absorption member 17 is provided at the upper end of the installation portion 166. When the liquid outlet 191 is opened, the liquid passing hole 167 is also communicated with the liquid outlet 191. In addition, a recessed groove 1611 communicating with the liquid passing hole 167 is formed by partially recessing the upper end surface of the base seal 161. The lower end surface of the liquid storage chamber 19 extends downward corresponding to the liquid outlet 191 to form an insertion portion 160 that cooperates with the recessed groove 1611. The insertion portion 160 is inserted into the recessed groove 1611, which can effectively prevent e-liquid leakage. At the same time, the chamber wall of the liquid storage chamber 19 that maintains a preset distance from the liquid outlet 191 is inclined. The inclined chamber wall can play a guiding role in the flow of e-liquid, which is beneficial to the smooth outflow of e-liquid.

[0180] On the upper end surface of the base seal 161, a gas guiding portion 168 protrudes upward. The gas guiding portion 168 is inserted into the air flow channel 165 from the lower end opening of the air flow channel 165, increasing the sealing performance of the air flow channel 165. A gas guiding groove 157 is provided on the base 15 corresponding to the gas guiding portion 168. One end of the gas guiding groove 157 penetrates the upper end surface of the base 15 along the axial direction of the cartridge 10 and then communicates with the gas guiding portion 168, and the other end of the gas guiding groove 157 penetrates the cavity wall of the atomization chamber 151 along the radial direction of the cartridge 10 and then communicates with the atomization chamber 151. The smoke in the atomization chamber 151 flows out successively through the gas guiding groove 157, the gas guiding portion 168, the air flow channel 165 and the smoke outlet 131. A communication groove 155 is provided on the base 15 opposite to the gas guiding groove 157. One end of the communication groove 155 penetrates the cavity wall of the atomization chamber 151 along the radial direction of the cartridge 10 and then communicates with the atomization chamber 151, and the other end of the communication groove 155 penetrates the lower end surface 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 atomization chamber 151 are arranged parallel to each other along the axial direction of the cartridge 10, that is, the two are arranged offset in the axial direction of the cartridge 10, which can prevent the condensate formed by the smoke in the atomization 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. In addition, a partition plate 156 is provided in the communication groove 155, and a gas passing hole 1561 is opened on the partition plate 156. The gas passing hole 1561 communicates with the air inlet 152 and the communication groove 155 respectively. The aperture of the gas passing hole 1561 is small, and it is difficult for the condensate to enter the air inlet 152 through the gas passing hole 1561 under the action of surface tension. Gas passing holes 1561 can also be opened on the cavity wall of the atomization chamber 151. The gas passing holes 1561 opened on the cavity wall of the atomization chamber 151 are used to communicate the atomization chamber 151 and the communication groove 155 to prevent the condensate from entering the communication groove 155.

[0181] In order to facilitate the injection of e-liquid into the liquid storage cavity 19, a groove 169 is provided on the upper end surface of the gasket 162 on both sides opposite to the seal 14. On both sides opposite to the seal 14 on the cigarette holder 13, a communication port (not shown in the figure) is provided respectively. During liquid injection, one of the communication ports serves as the liquid injection port, and the other communication port serves as the exhaust port. The liquid injection needle sequentially passes through the liquid injection port and the groove 169 corresponding to the liquid injection port and then extends into the liquid storage cavity 19 to inject e-liquid into the liquid storage cavity 19. The exhaust needle sequentially passes through the exhaust port and the groove 169 corresponding to the exhaust port and then extends into the liquid storage cavity 19 to discharge the gas in the liquid storage cavity 19 during the liquid injection process. After the liquid injection is completed, the liquid injection needle and the exhaust needle are withdrawn, and the gasket 162 forms a self-seal at the positions punctured by the liquid injection needle and the exhaust needle without leaking liquid. The provision of the groove 169 can reduce the thickness of the gasket 162, thereby facilitating the puncture of the liquid injection needle and the exhaust needle. During the entire liquid injection process, the liquid absorption member 17 and the liquid storage cavity 19 are always in a mutually isolated state, which can effectively prevent the e-liquid from leaking through the liquid absorption member 17 and also prevent the air from disturbing the liquid absorption member 17 and causing the position of the liquid absorption member 17 to shift. When sucking through the cigarette holder 13, the two communication ports are used as the smoke outlet 131.

[0182] In addition, please refer to Figure 5 、 Figure 6, a liquid collecting member 164 is further provided between the gasket 162 and the mouthpiece 13. The liquid collecting member 164 is used to absorb large particle e-liquid or condensate. Specifically, on the inner end face of the mouthpiece 13, a first communication pipe 132, a second communication pipe 133, and a third communication pipe 134 that are both penetrated at both ends are successively convex along the axial direction of the cartridge 10. Among them, the inner cavity of the first communication pipe 132 forms one of the communication ports, and the inner cavity of the third communication pipe 134 forms the other communication port. The operating portion 141 of the seal 14 penetrates through the inner cavity of the second communication pipe 133. On the inner end face of the mouthpiece 13, a plurality of reinforcing ribs 136 are further convex along the axial direction of the cartridge 10. The liquid collecting member 164 is clamped between the reinforcing ribs 136 and at least one of the first communication pipe 132, the second communication pipe 133, and the third communication pipe 134. In this embodiment, there are two liquid collecting members 164 and they are arranged oppositely. In a specific embodiment, the liquid collecting member 164 is cotton. The cotton is relatively soft and can be fully attached to the first communication pipe 132, the second communication pipe 133, the third communication pipe 134, and the reinforcing ribs 136, which can effectively prevent condensate or large particle e-liquid from entering the user's mouth through the liquid collecting member 164 and is beneficial to improving the liquid absorption capacity of the liquid collecting member 164. It can be understood that in other embodiments not shown, the liquid collecting member 164 can also be an element with liquid absorption capacity such as a fiber rope, a porous ceramic, or a porous graphite. In addition, a guiding groove 1621 and an installation groove 1622 are formed on the gasket 162 corresponding to the reinforcing ribs 136. When installing the mouthpiece 13, the reinforcing ribs 136 slide along the guiding groove 1621 so that part of the reinforcing ribs 136 is inserted into the installation groove 1622, thereby realizing the connection relationship between the mouthpiece 13 and the gasket 162.

[0183] Please refer to again Figure 4 , Figure 7, the mouthpiece 13 is sleeved outside the upper end of the cartridge housing 16. Both the mouthpiece 13 and the cartridge housing 16 are flat structures, which can effectively prevent the cartridge 10 from rolling off a bearing plane (e.g., a tabletop). Additionally, on the opposite side walls of the cartridge housing 16, there are protruding engaging protrusions 1601. Corresponding to the engaging protrusions 1601, engaging grooves 1301 are provided on the side walls of the mouthpiece 13. The engaging protrusions 1601 are snap-connected with the engaging grooves 1301, thereby realizing the connection relationship between the cartridge housing 16 and the mouthpiece 13 and preventing the mouthpiece 13 from being arbitrarily disassembled after installation. At the same time, one end of the mouthpiece 13 away from the cartridge housing 16 is the suction end, and the smoke outlet 131 is arranged on the suction end. The outer surface of the mouthpiece 13 contracts inward on the side maintaining a preset distance from the suction end and is set as an arc surface, which conforms to ergonomics and provides a good suction experience. When the cartridge 10 is installed in place, the suction end is located outside the battery housing 24. The cartridge housing 16 is made of a transparent or semi-transparent material. A notch 135 is provided on the part of the mouthpiece 13 corresponding to the liquid storage cavity 19, so that part of the cartridge housing 16 is exposed through the notch 135, thereby forming a window through which the liquid storage cavity 19 can be observed, facilitating the user to observe the usage amount or remaining amount of the e-liquid.

[0184] A dust-proof cover (not shown in the figure) is sleeved on the bottom of the cartridge 10 or the cartridge 10 is housed in a sealed bag (not shown in the figure) to prevent the liquid absorption member 17 from being contaminated before use and affecting the user's experience.

[0185] Please refer to Figures 9 to 13, the battery device 20 includes a heating element 21, a conductive post 231, and a battery device main body. The battery device main body includes a detection component 25, a battery housing 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 sheet, a heating mesh, a heating wire, or a heating rod. Among them, when using a heating sheet or a heating mesh, the contact area between the heating element 21 and the liquid absorption member 17 is large and uniform, which can uniformly heat the e-liquid on the liquid absorption member 17 and prevent local overheating. The heating element 21 can be made of a metal material, a ceramic material, or a metal-ceramic composite material. In a specific embodiment, the heating element 21 can adopt a ceramic heating sheet, in which tungsten paste is sintered in aluminum nitride ceramic, and the combination of the two is dense and the porosity is less than 1%, so that the heating element 21 can quickly heat up and the temperature distribution is uniform, but the type of the heating element 21 is not limited to this. Aluminum nitride ceramic means that its composition includes aluminum nitride. At the same time, the composition of the aluminum nitride ceramic can also include other substances, such as aluminum oxide. In addition to using aluminum nitride ceramic, the main body part of the heating element 21 can also be made of other ceramic materials, such as alumina or silicon nitride. In addition to 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 arranged in the battery housing 24, and the battery 233 is arranged on the battery bracket 23. The bracket seal 22 is sleeved outside the upper end of the battery bracket 23 and closely fits with the inner wall of the battery housing 24 to prevent the e-liquid from leaking into the interior of the battery device 20 through the gap between the battery housing 24 and the battery bracket 23. The conductive post 231 is arranged at the upper end of the battery bracket 23 and extends into the bracket seal 22. The conductive post 231 is used for electrically connecting 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 above the bracket seal 22 and an installation cavity 243 below the bracket seal 22. The battery bracket 23, the battery 233, and the first control board 29 are all located in the installation cavity 243. A part of the detection component 25 is located in the installation cavity 243, and the other part is located in the receiving cavity 242. The heating element 21 is located in the receiving cavity 242. Two pins 211 of the heating element 21 pass through the bracket seal 22 and are inserted into the conductive post 231 to realize the fixation of the heating element 21 and the electrical connection with the conductive post 231. The receiving cavity 242 plays a protective role for the heating element 21, which can prevent the heating element 21 from breaking when it touches a hard substance when the battery device 20 falls. In addition, 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, which can prevent the user's finger from touching the heating element 21, and further prevent the residual heat of the heating element 21 and the heat generated during self-cleaning from scalding the user. Please refer to Figure 15 and Figure 3, snap fasteners 241 are provided on two opposite cavity walls of the receiving cavity 242, and corresponding card slots 11 are provided on two opposite side walls of the cartridge housing 16. The snap fasteners 241 cooperate with the card slots 11, so that the cartridge 10 can be detachably mounted on the battery device 20. When the cartridge 10 is mounted on the battery device 20, a part of the cartridge 10 is received in the receiving cavity 242, which can prevent the cartridge 10 from shaking arbitrarily, improve the mounting stability of the cartridge 10, and can shorten the overall length of the electronic cigarette. In addition, it should be noted that when the cartridge 10 is mounted in place, the mouthpiece 13 is located outside the battery housing 24 for the user to suck. Moreover, a sliding groove 1612 is formed on the side wall of the cartridge housing 16 along the sliding direction of the snap fastener 241 relative to the card slot 11. During the installation process of the cartridge 10 and the battery device 20, the snap fastener 241 slides along the sliding groove 1612, and then disengages from the sliding groove 1612 and engages with the card slot 11. The setting of the sliding groove 1612 can guide the installation of the cartridge 10 and facilitate the operation.

[0186] When the cartridge 10 is connected to the battery device 20 in place, the heating element 21 extends into and is located in the atomization cavity 151 to maintain a preset distance or contact the liquid absorption member 17. The liquid absorption member 17 is used to supply e-liquid to the heating element 21 for atomization. When the cartridge 10 is mounted on the battery device 20, the mating portion 153 on the cartridge 10 contacts the detection assembly 25, and when the cartridge 10 is removed from the battery device 20, the mating portion 153 on the cartridge 10 is separated from the detection assembly 25. The detection assembly 25 is connected to the first control board 29. The detection assembly 25 is used to generate a separation signal when separated from the mating portion 153. The first control board 29 is used to control the heating element 21 to work according to the separation signal and preset parameters to remove the residues attached to the heating element 21. The detection assembly 25 is also used to generate a connection signal when contacting the mating portion 153. At this time, the first control board 29 cannot control the heating element 21 to work according to the preset parameters to remove the residues attached to the heating element 21. The residues include but are not limited to residual aerosol-forming matrix and carbides generated at high temperatures. When the separation signal is detected, the self-cleaning mode is started. In actual implementation, the heating element 21 is controlled to work at a higher power for a shorter time. For example, the heating element 21 is controlled to work 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 work. Removing the residues on the heating element 21 can prevent the residues from affecting the use of the electronic cigarette. For example, when the residue is residual e-liquid, it can prevent the residual e-liquid from entering the installation cavity 243 and affecting the electronic components in the installation cavity 243. In addition, self-cleaning is only performed after the cartridge 10 is removed, which can prevent the liquid absorption member 17 from carbonizing under the high temperature during self-cleaning.

[0187] The following provides two implementation manners of the detection assembly 25.

[0188] In the first embodiment, please refer to Figures 19 to 26 , the detection component 25 includes a sensor seal 26, a first chamber 253, a second chamber 254, a first sensor 251, and a second sensor 252. The first chamber 253 and the second chamber 254 are arranged on one side of the battery holder 23 and maintain a preset distance from the upper end of the battery holder 23. The sensor seal 26 is provided with a first part 261 and a second part 262 corresponding to the first chamber 253 and the second chamber 254 respectively. The first sensor 251 is installed in the first part 261 and placed in the first chamber 253. The opening of the first chamber 253 is communicated with the air inlet 152. The second sensor 252 is installed in the second part 262 and placed in the second chamber 254. The mating part 153 is a sealing protrusion, and the mating part 153 corresponds to the air guide groove 157 and protrudes downward on the lower end surface of the base 15. When the cartridge 10 is installed on the battery device 20, the mating part 153 blocks the opening of the second chamber 254. The first sensor 251 and the second sensor 252 are respectively connected to the first control board 29 to transmit the air flow signal to the first control board 29. Through the cooperation structure of the battery holder 23, the sensor seal 26, and the first control board 29, the first chamber 253 and the second chamber 254 can be made not to communicate with each other to avoid air flow interference. When the mating part 153 opens the opening of the second chamber 254 as the cartridge 10 is removed, a negative pressure will be generated in the second chamber 254, causing the second sensor 252 to detect the change in the internal air pressure and generate a corresponding air flow signal, that is, a high-level signal. At the same time, since the user does not suck on the electronic cigarette when removing the cartridge 10, and the first chamber 253 remains in communication with the outside, the air pressure in the first chamber 253 remains unchanged, and the first sensor 251 will not detect an air flow signal, that is, a low-level signal. Therefore, when the cartridge 10 is removed, the air flow signal of the first sensor 251 is low level and the air flow signal of the second sensor 252 is high level. When the air flow signal of the first sensor 251 is low level and the air flow signal of the second sensor 252 is high level, it can be considered that a separation signal indicating that the cartridge 10 has been removed from the battery device 20 is detected. It should be noted that when the types of the first sensor 251 and the second sensor 252 are different, the relevant information of the air flow for detection is different, which can be the flow rate of the air flow or the change in air pressure caused by the air flow. The first sensor 251 and the second sensor 252 generate air flow signals when detecting the relevant information of the corresponding air flow.

[0189] After detecting the separation signal, the self-cleaning mode is activated. The first control board 29 controls the heating element 21 to work according to preset parameters to remove the residues attached to the heating element 21. In actual implementation, the heating element 21 is controlled to work at a relatively high power for a short time. For example, it is heated for 1 second, and the power used for self-cleaning is higher than the power of the heating element 21 during atomization work. Removing the residues on the heating element 21 can prevent the residues from affecting the use of the electronic cigarette. For example, when the residue is residual e-liquid, it can prevent the residual e-liquid from entering the installation cavity 243 and affecting the electronic components in the installation cavity 243. In addition, self-cleaning is performed only after the cartridge 10 is removed, which can prevent the liquid absorption member 17 from carbonizing under the action of high temperature during self-cleaning.

[0190] Continuing from the above, please refer to Figure 22 and Figures 23 to 26 , the bracket seal 22 is provided with a jack 224 for inserting the pins of the heating element 21, an air inlet hole 222 communicating with the opening of the first chamber 253, a through hole 223 communicating with the opening of the second chamber 254, and an air inlet notch 221. The jack 224 is opened on the upper end surface of the bracket seal 22. The air inlet hole 222 and the through hole 223 are located on opposite sides of the jack 224. The pins of the heating element 21 are inserted into the conductive column 231 after passing through the jack 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 hole 222. The mating portion 153 of the cartridge 10 closes or opens the opening of the second chamber 254 through the through hole 223 communicating with the opening of the second chamber 254. In addition, please combine Figure 19 , an air inlet groove 12 is formed on the side wall of the cartridge housing 16. The air inlet groove 12 on the cartridge 10 and the battery housing 24 of the battery device 20 cooperate to form an air inlet passage, so that external gas can enter the electronic cigarette. The gas entering the electronic cigarette enters the atomization chamber 151 of the cartridge 10 and flows out from the air guide groove 157, the air guide portion 168, the air flow passage 165, and the smoke outlet 131, carrying the smoke in the atomization chamber 151. Please combine Figure 22, a first vent 245 is formed in the battery housing 24, a second vent 236 is formed in the side wall at the upper end of the battery bracket 23, the intake notch 221 is respectively communicated with the first vent 245 and the second vent 236, and the second vent 236 is also communicated with the opening of the first chamber 253. Thus, when sucking on the electronic cigarette, external gas enters through the first vent 245, the intake notch 221 and the second vent 236. When flowing through the opening of the first chamber 253, it takes away the air in the first chamber 253, and then flows out from the intake hole 222, the intake port 152, the communication groove 155, the atomization chamber 151, the air guide groove 157, the air guide portion 168, the air flow channel 165 and the smoke outlet 131, so that a negative pressure is generated in the first chamber 253. The first sensor 251 detects the change in air pressure and generates a corresponding air flow signal, that is, generates a high-level signal. At this time, the opening of the second chamber 254 is closed by the mating portion 153, there is no change in air pressure in the second chamber 254, and the second sensor 252 remains in the state of outputting a low-level signal. When the air flow signal of the first sensor 251 is high level and the air flow signal of the second sensor 252 is low level, it is considered that the atomization start signal is detected. After detecting the atomization start signal, the atomization mode is started, and the first control board 29 controls the heating element 21 to work according to preset parameters to atomize the e-liquid on the liquid absorbing member 17. It can be understood that the external gas entering from the first vent 245 can also take away the smoke in the atomization chamber 151 after entering the atomization chamber 151.

[0191] It should be noted that when the user does not perform any sucking and disassembly operations on the electronic cigarette, there is no change in air pressure in both the first chamber 253 and the second chamber 254, and both the first sensor 251 and the second sensor 252 remain in the state of outputting low-level signals, and the heating element 21 does not work, that is, neither self-cleaning nor atomization is performed. When the user only sucks on the battery device 20, the air in both the first chamber 253 and the second chamber 254 is sucked out, and both the first chamber 253 and the second chamber 254 are in negative pressure. Both the first sensor 251 and the second sensor 252 generate high-level signals. At this time, the heating element 21 also does not work. Thus, it is possible to prevent the heating element 21 from working under abnormal conditions.

[0192] In order to prevent the condensate of the smoke or the leaked e-liquid from entering the first chamber 253 and the second chamber 254 and affecting the operation of the first sensor 251 and the second sensor 252. As Figure 26 shown, a part of the upper end surface of the battery bracket 23 is recessed downward to form a first receiving groove 237 and a second receiving groove 238. A communicating portion 239 protrudes upward along the axial direction of the battery device 20 on the bottom wall of the first receiving groove 237, and the communicating portion 239 is respectively communicated with the first receiving groove 237 and the opening of the first chamber 253. Please combine Figure 24, a partition portion 229 protrudes downward on the upper end surface of the bracket seal 22. When the bracket seal 22 is installed in place, the air inlet hole 222 and the communication portion 239 are located on opposite sides of the partition portion 229, that is, the air inlet hole 222 and the communication portion 239 are arranged staggeredly. Since the communication portion 239 protrudes and the air inlet hole 222 and the communication portion 239 are arranged staggeredly, even if the condensate of the smoke or the leaked smoke liquid enters the battery device 20, it cannot enter the first chamber 253 through the air inlet hole 222 and the communication portion 239, but remains in the first receiving groove 237. Under the suction action of the user, the external gas enters the first receiving groove 237 through the first ventilation port 245, the air inlet notch 221 and the second ventilation port 236, and then flows out through the air inlet hole 222, the air inlet 152, the communication groove 155, the atomization chamber 151, the air guide groove 157, the air guide portion 168, the air flow 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 communication portion 239 and the first receiving groove 237, so that a negative pressure is generated in the first chamber 253. The first sensor 251 detects the change in air pressure and generates a corresponding air flow signal, that is, generates 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. Or, a deformable member is provided at the opening of the first chamber 253. Under the suction action of the user, the deformable member deforms, so that the space formed by enclosing the first chamber 253 and the deformable member becomes larger, the air pressure in this space decreases, the first sensor 251 detects the change in air pressure and generates a corresponding air flow signal. When the suction stops, the deformable member returns to its original shape and the air pressure in this space returns. The deformable member isolates liquids such as condensate or leaked smoke liquid outside the first chamber 253. In this embodiment, the detection assembly 25 further includes a deformable portion 225, which is formed by protruding downward a part of the upper end surface of the bracket seal 22 corresponding to the through hole 223. The deformable portion 225 is a hollow structure with an open upper end. Please refer to Figure 22When the bracket seal 22 is installed on the battery bracket 23, the deformed portion 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 is connected to the opening of the second cavity 254 and the second receiving groove 238 respectively. The deformed portion 225 closes the opening of the second cavity 254 by closing the connecting hole 230. At this time, the deformed portion 225 cooperates with the second cavity 254 to form a closed space for accommodating the second sensor 252. When the cigarette cartridge 10 is installed in place, the matching portion 153 is inserted into the deformed portion 225 through the through hole 223 to seal the deformed portion 225, which is equivalent to sealing the opening of the second cavity 254. When the cigarette cartridge 10 is pulled out, the deformed portion 225 is deformed under the action of the matching portion 153, and the enclosed space formed by the second cavity 254 and the deformed portion 225 becomes larger, so that negative pressure is generated in the space, and the second sensor 252 detects the change in air pressure and generates a corresponding airflow signal, that is, a high-level signal. The deformed portion 225 isolates the second sensor 252 in the second cavity 254 from the outside world, thereby preventing condensed liquid or leaked smoke liquid from entering the second cavity 254 and affecting the normal operation of the second sensor 252.

[0193] It can be understood that the deformation part 225, as a part of the detection component 25, can also be directly arranged 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 closed space for accommodating the second sensor 252. At this time, the through hole 223 on the bracket seal 22 is arranged to pass through the upper end surface and the lower end surface of the bracket seal 22, so that when the cigarette cartridge 10 is installed in place, the matching part 153 is inserted into the deformation part 225 through the through hole 223 to seal the deformation part 225. At the same time, the deformation part 225 can separate the second sensor 252 in the second cavity 254 from the outside world to prevent condensed liquid or leaked smoke liquid from entering the second cavity 254. In addition, the second sensor 252 generates an airflow signal by detecting the air pressure change in the cavity where it is located. Therefore, it is only necessary to ensure that the cavity where the second sensor 252 is located has no air pressure change after the cigarette cartridge 10 is installed and that the air pressure change can occur when the cigarette cartridge 10 is removed. The air pressure change can be the air pressure change directly caused by the matching part 153 being pulled out relative to the second cavity 254 when there is no deformation part 225, or the air pressure change caused by the matching part 153 being pulled out relative to the second cavity 254 when the deformation part 225 is provided. In this case, the opening of the deformation 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 cigarette cartridge 10 is installed, and in an open state after the cigarette cartridge 10 is removed, thereby generating the above-mentioned air pressure change.

[0194] The battery device 20 is provided with a dual-sensor structure, which can cooperate with the mating part 153 on the cartridge 10 to generate a signal when the cartridge 10 is removed, so that the electronic cigarette can automatically remove the residues on the heating element 21 when the cartridge 10 is removed, realizing self-cleaning and improving the service life of the heating element 21 and the electronic components in the battery device 10.

[0195] In the second embodiment, a mating part 153 is formed on one side of the lower end surface of the base 15 opposite to the air inlet 152. The detection assembly 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 cooperates with the mating part 153 and is in a conducting state. When the cartridge 10 is removed from the battery device 20, the cooperation between the state detection circuit and the mating part 153 is released and it is 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, a switching element 653 is provided in the state detection circuit. When the cartridge 10 is installed on the battery device 20, the mating part 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 part 153 and resets, so that the state detection circuit is disconnected to generate a separation signal.

[0196] Please refer to Figure 13, in actual implementation, the switch element 653 includes a thimble 651 and a switch button 652. The battery device 20 is provided with a thimble installation through hole (not shown in the figure) on the side where the cartridge 10 is installed. The thimble 651 is inserted through the thimble installation through hole. The thimble 651 protrudes outside the bracket seal 62 and corresponds to the mating portion 153 on the cartridge 10. The thimble 651 is connected to an elastic element and can automatically reset after the external force is removed. The switch button 652 is arranged on the first control board 29 where the state detection circuit is located and corresponds to the position of the thimble 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 portion 153 presses the switch button 652 to the closed position through the thimble 651. When the cartridge 10 is removed from the battery device 20, the thimble 651 resets under the action of the corresponding elastic element, and then the switch button 652 resets 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 thimble 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 thimble 651 to reset. The mating portion 153 that can push the thimble 651 can be a surface, groove or protrusion on the base 15 of the cartridge 10, as long as it can press down the thimble 651 along with the movement of the cartridge 10, and there is no limitation on the shape. It can be understood that the reset elements for driving the thimble 651 and the switch button 652 to reset can be other elements in addition to the elastic element. For example, magnetic elements. Specifically, a pair of magnetically repulsive magnetic elements are arranged in the switch button 652. In the natural state, under the action of the repulsive force, the switch button 652 is in the open position. When the thimble 651 presses the switch button 652, by overcoming the repulsive force, the switch button 652 is pressed to the closed position.

[0197] It can be understood that the structure of the switch element 653 in this embodiment is not limited to this. For example, the switch element 653 is only a switch button, and at the same time, the mating portion 153 arranged on the cartridge 10 is 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. Or, the switch element 653 is only a switch button, and the top end of the switch button protrudes outside the bracket seal 22. At the same time, the mating portion 153 arranged on the cartridge 10 is 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.

[0198] The battery device 20 is provided with a state detection circuit and a resetable 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, so that the electronic cigarette can automatically remove the residues on the heating element 21 when the cartridge 10 is removed, realizing self-cleaning and improving the service life of the heating element 21 and the electronic components in the battery device 20.

[0199] In the above two 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 is used to generate a separation signal when separating from the mating part and generate a connection signal when contacting the mating part. It can be understood that in other embodiments not shown, the mating part and the detection component can also adopt other cooperation methods, as long as a separation signal is generated by the detection component when the cartridge is removed from the battery device, and a connection signal is generated by the detection component when the cartridge is connected to the battery device. For example, the mating part and the detection component may not contact each other all the time. 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, so that the light sensor detects the light beam, and the light sensor generates a connection signal therefrom. When the cartridge is removed, the light beam cannot be reflected, so that the light sensor detects the disappearance of the light beam, and the light sensor generates a separation signal therefrom.

[0200] Please refer to again Figure 12 、 Figure 13, a cavity 61 is provided inside the battery holder 23. The battery device 20 further includes a sensor seal 26 and a sensor 66. The sensor 66 is connected to the first control board 29, installed inside the sensor seal 26 and placed into the cavity 61. The cavity 61 communicates with the mouthpiece 13. The sensor 66 is used to detect the air flow state inside the cavity 61. When, under the suction of the user, the air inside the cavity 61 is sucked out, causing a negative pressure inside the cavity 61, the sensor 66 generates an air flow signal. The first control board 29 is used to control the heating element 21 to perform atomization work according to the air flow signal. Thus, when the status detection circuit is turned on, the electronic cigarette confirms that the cartridge 10 is in the installed state. At this time, it is judged whether the user performs a suction operation according to the air flow signal of the sensor 66. When the user sucks the electronic cigarette, the air inside the cavity 61 is sucked out, and the cavity 61 is in a negative pressure state. The sensor 66 generates an air flow signal with a high level. 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 and then performs atomization work. It should be noted that after the first control board 29 receives the separation signal that the cartridge 10 is removed from the battery device 20, it indicates that the cartridge 10 has been removed. At this time, even if an air flow signal with a high level 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 work, which can effectively play a child protection function and prevent the battery device 20 from being accidentally triggered when only sucking on the opening of the battery device 20. In this embodiment, the sensor 66 is an air flow sensor, which is used to generate an air flow signal when air flows. It can be understood that in other embodiments not shown, the sensor 66 is a pressure sensor, which is used to generate an air flow signal when air flows out, causing a negative pressure inside the cavity 61. It can be understood that when the type of the sensor 66 is different, the relevant information of the air flow detected is different, which can be the flow rate of the air flow or the pressure change caused by the air flow. The sensor 66 generates an air flow signal when detecting the corresponding relevant information of the air flow. It can be understood that the above air flow signal constitutes a suction signal, that is, when the detection component 25 generates a connection signal and at the same time 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 work.

[0201] Please refer to Figure 10 , Figure 11, at the center of the upper end face of the bracket seal 22, a convex post 226 extends upward along the axial direction of the bracket seal 22. A liquid collecting groove 2211 is formed by downward depression at the top of the convex post 226. Two jacks 224 penetrating the upper and lower end faces of the bracket seal 22 are provided at the top of the liquid collecting groove 2211. Two pins 211 of the heating element 21 respectively pass through the jacks 224 and are connected to the corresponding conductive posts 231 and electrically conducted. During actual use, the condensate generated when the smoke is cooled can be collected in the liquid collecting groove 2211, preventing the condensate from entering the interior of the battery device 20 and damaging other components. Moreover, the liquid collecting groove 2211 is provided at a preset distance from the heating element 21. The heat generated after the heating element 21 is powered on can atomize the condensate in the liquid collecting groove 2211, realizing the cleaning effect on the condensate in the liquid collecting groove 2211. Additionally, it should be noted that when the cartridge 10 is installed in place, the convex post 226 is inserted into the atomization cavity 151, and the cavity wall of the atomization cavity 151 fits with the outer surface of the convex post 226. Thus, the condensate in the atomization cavity 151 can only enter the liquid collecting groove 2211 and will not leak to other places.

[0202] An air intake notch 221 is formed on one side of the convex post 226 on the upper end surface of the bracket seal 22, and the air intake notch 221 corresponds to the air intake port 152. A vent port 245 is formed on the side wall of the battery housing 24, and the vent port 245 is in communication with the external atmosphere and the air intake notch 221. An induction tube 2212 protrudes from the upper end surface of the battery bracket 23. The induction tube 2212 has a tubular structure with both ends penetrating. The inner cavity of the induction tube 2212 forms an induction channel 2213. The lower end of the induction channel 2213 is in communication with the cavity 61. The upper end of the induction tube 2212 passes through the bracket seal 22 and extends into the air intake notch 221. When the cartridge 10 and the battery device 20 are installed in place, both the air intake notch 221 and the induction channel 2213 are in communication with the air intake port 152. When the user sucks on the electronic cigarette, the external gas enters the air intake notch 221 through the vent port 245. When flowing through the upper port of the induction channel 2213, it takes away the air in the cavity 61, and then flows out from the air intake port 152, the communication groove 155, the atomization chamber 151, the air guide groove 157, the air guide portion 168, the air flow channel 165, and the smoke outlet 131, causing a negative pressure in the cavity 61. The sensor 66 generates an air flow 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 energized and then performs the atomization work. When the external gas flows into the atomization chamber 151, it can carry the smoke and flow out from the air guide groove 157, the air guide portion 168, the air flow channel 165, and the smoke outlet 131 for the user to suck. In addition, a waterproof and breathable membrane (not shown in the figure) can be installed at the upper end opening of the induction tube 2212, so that the condensate cannot enter the cavity 61 and further prevent the condensate from contacting the sensor 66, while the air in the cavity 61 can be sucked smoothly, enabling the sensor 66 to detect relevant information about the air flow. It can be understood that the waterproof and breathable membrane can also be provided at other positions, as long as the sensor 66 is isolated from the air intake port 152. For example, the waterproof and breathable membrane can be provided in the cavity 61, or in the induction channel 2213. It can be understood that 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 in the space formed by the enclosure of the deformable member and the cavity 61. When the user sucks, the deformable member deforms, and the volume of this space increases, causing the air pressure in this space to decrease. The sensor 66 detects the change in air pressure and generates a corresponding air flow signal. When the suction stops, the deformable member returns to its original shape, and the air pressure in this space returns. The deformable member isolates the condensate or leaked smoke liquid and other liquids outside the cavity 61.

[0203] Please refer to again Figure 2, in this embodiment, the opening of the battery housing 24 is provided as an inclined opening, and one surface of the mouthpiece 13 is correspondingly provided as an inclined surface. When the cartridge 10 is installed in place with the battery device 20, the inclined opening of the battery housing 24 cooperates with the inclined surface of the mouthpiece 13. In this way, when the cartridge 10 is installed, the cartridge 10 can only be inserted into the receiving cavity 242 in a single direction, ensuring that the induction 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) which are oppositely arranged. The second end is the open end, and the cartridge 10 is detachably inserted into the battery housing 24 through the open end. 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, and the diameter of the open end is small, making it difficult for the user's finger to reach in. Thus, the user can be prevented from touching the heating element 21. The battery housing 224 has a first limiting portion (not shown in the figure) and a second limiting portion (not shown in the figure). The distance from the first limiting portion to the first end is less than the distance from the second limiting portion to the first end. Correspondingly, the mouthpiece 13 is provided with a first positioning portion (not shown in the figure) and a second positioning portion (not shown in the figure). The distance from the first positioning portion to the suction end is greater than the distance from the second positioning portion to the suction end. When the cartridge 10 and the battery device 20 are assembled in place, the first positioning portion abuts against the first limiting portion, and the second positioning portion abuts against the second limiting portion. If, during assembly, the first positioning portion is opposite to the second limiting portion and the second positioning portion is opposite to the first limiting portion, the cartridge 10 cannot be installed in place. In this embodiment, two opposite surfaces of the battery housing 24 constitute a first limiting surface and a second limiting surface. Both the first limiting surface and the second limiting surface extend along the axial direction of the battery device 20 from the first end to the second end, and the distance that the first limiting surface extends in the axial direction of the battery device 20 is less than the distance that the second limiting surface extends in the axial direction of the battery device 20. The side edge of the first limiting surface at the second end is the first limiting portion, and the side edge of the second limiting surface at the second end is the second limiting portion. Correspondingly, two opposite surfaces of the mouthpiece 13 constitute a first positioning surface and a second positioning surface. Both the first positioning surface and the second positioning surface extend along the axial direction of the cartridge 10 from the suction end, and the distance that the first positioning surface extends in the axial direction of the cartridge 10 is greater than the distance that the second positioning surface extends in the axial direction of the cartridge 10. The side edge of the first positioning surface away from the suction end is the first positioning portion, and the side edge of the second positioning surface away from the suction end is the second positioning portion. It can be understood that in other embodiments, the first limiting portion and the second limiting portion can also adopt other setting 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 only need not be symmetrically arranged along the central axis of the cartridge 10.For example, the first limiting portion and the second limiting portion may be located on the same side edge of the open end of the battery housing 24. Specifically, this side edge is an inclined side. The lower end of the inclined side is the first limiting portion, and the higher end of the inclined side is the second limiting portion. Correspondingly, the first positioning portion and the second positioning portion are located on the same side edge of the mouthpiece 13 away from the suction end. This side edge is an inclined side. The end of the inclined side farther from the suction end is the first positioning portion, and the end of the inclined side closer to the suction end is the second positioning portion.

[0204] Please refer to again Figure 11 , in a specific embodiment, at least one through groove 212 penetrating the upper and lower surfaces of the heating element 21 is formed in the heating element 21, which can facilitate the outflow of the smoke after passing through the heating element 21. On the other hand, when the cartridge 10 is installed in place, the liquid absorbing member 17 can be deformed under an external force and partially accommodated in the through groove 212. In this way, the liquid absorbing member 17 can not only contact the surface of the heating element 21, but also contact the groove wall of the through groove 212, increasing the contact area between the heating element 21 and the liquid absorbing member 17, and thus improving the atomization efficiency. The length of the through groove 212 is 1-2 mm, and the width is 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, and parts for installing the lead pins 211 are left at both ends of the heating element 21. On the other hand, the width of the through groove 212 is small, which can prevent the e-liquid from leaking through the through groove 212.

[0205] In addition, the heating element 21 is in the shape of a thin sheet, and the thickness of the heating element 21 is 0.2-3 mm. In a specific embodiment, the thickness of the heating element 21 is 0.45-0.55 mm. If the heating element 21 is too thick, it is not conducive to heat conduction. If it is too thin, the strength is insufficient and the heating element 21 is prone to breakage. The selection range of the maximum width of the heating element 21 is 1.5-4.5 mm. In a specific embodiment, the selection range of the maximum width of the heating element 21 is 2.5-3.5 mm. The selection range of the maximum length of the heating element 21 is 2.5-13.5 mm. In a specific embodiment, the selection range of the maximum length of the heating element 21 is 4-5 mm. When the maximum width and maximum length of the heating element 21 are within the above ranges, it can be ensured that the heating element 21 can smoothly pass through the lower end opening of the atomization chamber 151, and it can be ensured that the heating element 21 has a sufficient heating area. Through holes (not shown in the figure) are formed on both sides of the heating element 21, and the through groove 212 is located between the two through holes. After the lead pins 211 are inserted into the through holes, they are welded and fixed to the heating element 21. The lead pins 211 are made of a hard material, so that during the installation process of the cartridge 10, the heating element 21 will not be deformed or displaced under pressure.

[0206] In addition, please refer to Figure 14, the conductive post 231 for installing the heating element 21 is an elastic conductive post. In this way, during installation, the heating element 21 is in elastic contact with the liquid absorption element 17, thereby allowing a certain processing error to ensure that the heating element 21 and the liquid absorption element 17 are in mutual fit. In a specific embodiment, the conductive post 231 includes a first connection portion and a second connection portion. The first connection portion is relatively fixed to the heating element 21, and the second connection portion is relatively fixed to the battery device main body. The first connection portion can move away from or towards the second connection portion under the action of an external force. Specifically, the first connection portion is a fixed tube 2314 and a claw 2315 installed inside one end of the fixed tube 2314, and the second connection portion is an outer sleeve tube 2311. The fixed tube 2314 is movably disposed inside the outer sleeve tube 2311. The conductive post 231 further includes an elastic member 2312 and an insulating member 2313 housed inside the outer sleeve tube 2311. One end of the elastic member 2312 elastically abuts against the lower end of the outer sleeve tube 2311, and the other end of the elastic member 2312 elastically abuts against the insulating member 2313. The lower end of the fixed tube 2214 contacts the insulating member 2213. When pressing the fixed tube 2314, the fixed tube 2314 can compress the elastic member 2312 through the insulating member 2313 and then retract into the outer sleeve tube 2311. When the pressing action on the fixed tube 2314 is released, the fixed tube 2314 moves upward under the reset action of the elastic member 2312 and partially extends outside the outer sleeve tube 2311. The claw 2315 includes a clamp 2317 fixedly connected to the inner wall of the outer sleeve tube 2311 and a clamping portion 2318 installed on the lower end surface of the clamp 2317. One end of the clamping portion 2318 relative to the clamp 2317 is bent towards the central axis of the clamp 2317, and the clamping portion 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 clamping portion 2318 to achieve the fixation of the heating element 21, which is simple and convenient to operate. In addition, the insulating member 2313 is arranged between the elastic member 2312 and the fixed tube 2314, so that the elastic member 2312 and the fixed tube 2314 are isolated from each other through the insulating member 2313 and do not contact each other, and the insulating member 2313 is made of an insulating material. The size of the conductive post 231 is small, which makes the elastic member 2312 installed inside the conductive post 231 very small. Assuming that there is an electric current passing through the elastic member 2312, the elastic member 2312 is very easy to burn out. Under the action of the insulating member 2313, when energized, the electric current does not flow through the elastic member 2312, but flows through the outer sleeve tube 2311, the fixed tube 2314, and the claw 2315, which can prevent the phenomenon that the elastic member 2312 is damaged due to the electric current passing through the elastic member 2312 and causing the elastic member 2312 to generate heat when the heating element 21 works. On the other hand, the insulating member 2313 is an insulating ball, which can play a positioning role for the elastic member 2313, preventing the position of the elastic member 2312 from shifting during multiple pressing and resetting processes, resulting in the failure of the elastic member 2312.Understandably, the elastic member 2312 includes, but is not limited to, elastic and rigid elements such as springs, stainless steel shrapnel, or copper shrapnel.

[0207] Please refer to Figure 12 , Figure 13 and Figure 15 , in the present invention, the battery 233 is a rechargeable battery. A charging connection part (not shown in the figure) is provided on one side of the battery device 20 away from the heating element 21. The charging connection part includes a second control board 235, a connecting column 281, and a contact electrode 282. The contact electrode 282 is connected to the second control board 235 through the connecting column 281. A through hole for exposing the contact electrode 282 is provided on the battery bracket 23. Correspondingly, please refer to Figure 16 , a charging base 40 for charging the battery 233 is provided with an e-cigarette connection part 41 and a power connection part 42. The e-cigarette connection part 41 is provided with an e-cigarette slot 411 and a charging post located in the e-cigarette slot 411. The e-cigarette slot 411 is used to fix the e-cigarette, and the charging post is used to electrically connect with 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 a plug. The e-cigarette connection part 41 and the power connection part 42 form a set angle, 90° < set angle < 180°, for example, 155°, so as to avoid interference between the e-cigarette and the protruding objects on the wall during charging and facilitate the user's access.

[0208] Please refer to again Figure 12 , Figure 13 and Figure 15 , in order to enable the user to clean the residue on the heating element 21 according to their own needs, in this embodiment, an operation part 27 is further provided on the battery device 20. 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 user's operation. A through hole for accommodating the operation part 27 is provided at the lower end of the battery bracket 23. When the self-cleaning function needs to be used, the user can insert a tool into the through hole to press the operation part 27 to trigger it. The operation part 27 is set in a concealed manner, so as to avoid misoperation.

[0209] In addition, please refer to Figure 1 , Figure 12 and Figure 13 , in order to facilitate the user to understand the usage status of the e-cigarette, an indicator light 30 is further provided on the battery device 20. The indicator light 30 is fixed on the battery bracket 23 through the lamp post cover 232 and is connected to the first control board 29. A through hole for observing the indicator light 30 is provided on the battery housing 24.

[0210] The control method of the e-cigarette in the above embodiment will be described in detail below.

[0211] Please refer to Figure 18 , the control method of the electronic cigarette in this embodiment includes but is not limited to the following steps:

[0212] Step S1, detecting a separation signal generated when the cartridge is removed from the battery device. Among them, an aerosol-forming substrate is stored in the cartridge, and a heating element is provided on the battery device. The heating element is used to heat the aerosol-forming substrate in the cartridge when powered on;

[0213] Step S2, when the separation signal is detected, controlling the heating element to work to remove the residues on the heating element.

[0214] The electronic cigarette of the present invention includes a cartridge and a battery device, and the cartridge and the battery device are detachably connected. An aerosol-forming substrate is stored in the cartridge, and the aerosol-forming substrate can be substances such as e-liquid, tobacco paste, and tobacco leaves that can generate inhalable smoke. The battery device is provided with a heating element, and the heating element is used to heat the aerosol-forming substrate in the cartridge to form smoke when powered on. When the cartridge is removed from the battery device, the cartridge is separated from the heating element. At this time, residues left during use may adhere to the heating element. The residues are, for example, the aerosol-forming substrate remaining on the heating element or carbides generated by heating. In one embodiment, the aerosol-forming substrate is e-liquid, and a corresponding liquid-absorbing member is provided on the cartridge to supply e-liquid to the heating element. When the cartridge is installed on the battery device, the liquid-absorbing member contacts or approaches the heating element, so that the e-liquid stored in the cartridge can be supplied to the heating element for atomization.

[0215] Corresponding to the above first embodiment, when a first sensor and a second sensor are provided on the battery device, the step of detecting a separation signal generated when the cartridge is removed from the battery device includes:

[0216] Obtaining a first air flow signal of the first sensor and a second air flow signal of the second sensor. Among them, the first sensor is arranged in a first cavity on the battery device, and the second sensor is arranged in a second cavity on the battery device. The first cavity is communicated with the air flow channel of the electronic cigarette and is isolated from the second cavity. The second cavity is in a closed state when the cartridge is installed on the battery device and is in an open state after the cartridge is removed from the battery device;

[0217] If the first air flow signal is at a low level and the second air flow signal is at a high level, it is detected that a separation signal is generated when the cartridge is removed from the battery device.

[0218] Among them, the first sensor is arranged in the first cavity on the battery device, and the second sensor is arranged in the second cavity on the battery device. The first cavity is connected with the airflow channel of the electronic cigarette, and the first cavity and the second cavity are not connected with each other but isolated from each other. The second cavity is in a closed state when the cigarette cartridge is installed on the battery device and is in an open state after the cigarette cartridge is removed from the battery device. In actual implementation, a sealing part is provided on the cigarette cartridge, and the sealing part is inserted into the opening of the second cavity and blocks the opening when the cigarette cartridge is installed on the battery device. In this way, when the cigarette cartridge is removed from the battery device, a negative pressure will be generated in the second cavity due to the withdrawal 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 will not inhale when removing the cigarette cartridge, there is no airflow passing through the airflow channel of the electronic cigarette, and the air pressure in the first cavity will not change when the cigarette cartridge is pulled out. Therefore, the first airflow signal of the first sensor is a low-level signal. Therefore, when the first airflow signal is low and the second airflow signal is high, it can be considered that the cigarette cartridge is currently being removed from the battery device. The first airflow signal is low and the second airflow signal is high, which is equivalent to a separation signal that the cigarette cartridge is removed from the battery device.

[0219] When the separation signal is detected, the electronic cigarette controls the heating element to work to remove the residue on the heating element. In actual implementation, the electronic cigarette controls the heating element to work according to the preset parameters, thereby starting the self-cleaning mode to remove the residue on the heating element. Among them, the preset parameters include one of the preset working voltage, the preset temperature and the preset power and the preset working time. The preset working voltage is greater than the working voltage when the electronic cigarette is in the suction state. The preset working voltage can also be equal to the current output voltage of the battery. The preset temperature is greater than the working temperature when the electronic cigarette is in the suction state. The working temperature is also the atomization temperature when the heating element is working normally. The preset power is greater than the working power when the electronic cigarette is in the suction state. The working power is also the atomization power when the heating element is working normally. By adopting a higher working voltage, working temperature or working power, the attached residue can be quickly consumed in a shorter time. The preset working time is a shorter time, for example, 1 second. Of course, in actual implementation, the heating element is controlled to work according to the corresponding working parameters when the electronic cigarette is in the suction state, and the residue on the heating element can also be removed. The only difference is the length of the elimination time.

[0220] When the battery device is provided 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:

[0221] If the first airflow signal and the second airflow signal are both at a low level or both at a high level, the heating element is controlled not to work.

[0222] Among them, if both the first airflow signal and the second airflow signal are at a low level, it indicates that the electronic cigarette is in an idle state and the heating element does not work. When the electronic cigarette is puffed without a cartridge installed, there will be airflow in both the first chamber and the second chamber, and both the first airflow signal and the second airflow signal are at a high level. If a child obtains the electronic cigarette and puffs on it at this time, controlling the heating element to work will cause burns. Therefore, when both the first airflow signal and the second airflow signal are at a high level, the heating element does not work.

[0223] When the battery device is provided with a first sensor and a second sensor located in the first chamber and the second chamber respectively, the control method of the electronic cigarette may further include the following steps:

[0224] If the first airflow signal is at a high level and the second airflow signal is at a low level, the heating element is controlled to work according to the working parameters corresponding to the suction state of the electronic cigarette.

[0225] Among them, when the user puffs on the electronic cigarette, there is airflow in the airflow channel of the electronic cigarette, and the airflow signal generated by the first sensor is at a high level. At this time, the installation state of the cartridge is judged by combining the airflow signal of the second sensor. When the user puffs on the electronic cigarette, only when the second chamber is in a closed state will the second sensor not detect a change in airflow. It can be seen that if the second airflow signal is at a low level at this time, it indicates that the second chamber is in a closed state and the cartridge is installed on the electronic cigarette. Therefore, when the first airflow signal is at a high level and the second airflow signal is at a low level, it indicates that the cartridge has been installed and the user is puffing. At this time, the electronic cigarette controls the heating element to work according to the working parameters corresponding to the suction state of the electronic cigarette, that is, controls the heating element to perform normal atomization work.

[0226] After controlling the heating element to work according to the working parameters corresponding to the suction state of the electronic cigarette, the control method of the electronic cigarette may further include the following steps:

[0227] If the duration for the resistance value of the heating element to rise to the preset resistance value is less than the preset duration, control the heating element to stop working;

[0228] If the duration for the resistance value of the heating element to rise to the preset resistance value is greater than or equal to the preset duration, control the heating element to output power so that the resistance value of the heating element remains at the preset resistance value.

[0229] Among them, the preset resistance value is the atomization resistance value when the electronic cigarette performs atomization work and is the normal working resistance value. Usually, when the electronic cigarette leaves the factory, an atomization temperature will be set, and this atomization temperature corresponds to a resistance value of the heating element. When the electronic cigarette is working, the battery device outputs voltage to the heating element to make the heating element 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, by controlling the output power, the resistance value of the heating element is stabilized at this resistance value, that is, the aforementioned atomization resistance value. Of course, the atomization resistance value can also be calculated according to the atomization temperature or power actually set by the user. During the heating process of the electronic cigarette, if the duration for the resistance value of the heating element to rise to the preset resistance value is less than the preset duration, it indicates that the heating element has overheated due to dry burning and the temperature has risen too fast. To protect the cartridge, heating is stopped at this time; if the duration for the resistance value of the heating element to rise to the preset resistance value is greater than or equal to the preset duration, it indicates that the heating element is working normally. At this time, by controlling the output power of the heating element, the resistance value of the heating element is stabilized at the preset resistance value. The resistance value being stable means that the deviation of the resistance value of the heating element from the preset resistance value is within a relatively small range.

[0230] In another embodiment, corresponding to the above second embodiment, when a status 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:

[0231] Obtain the on-off signal of the status detection circuit. Among them, the status detection circuit is used to detect the installation status of the cartridge. The status detection circuit is provided on the battery device. The status detection circuit is in a conducting state when the cartridge is installed on the battery device, and the status detection circuit is in a disconnected state when the cartridge is separated from the battery device;

[0232] If the on-off signal is a disconnection signal, then the separation signal generated when the cartridge is removed from the battery device is detected.

[0233] Among them, the state detection circuit is arranged on the battery device for detecting the installation state of the cigarette cartridge. In this embodiment, a switch element for turning on and off the state detection circuit is provided in the state detection circuit. The switch element includes an elastic element and a switch button connected to the elastic element. When the cigarette cartridge is installed on the battery device, the cigarette cartridge presses the switch button on the switch element by pressing the ejector pin arranged on the battery device or the ejector rod arranged on the cigarette cartridge. The elastic element in the switch element is in a deformed state, and the switch element is closed to turn on the state detection circuit. At this time, the on-off signal of the state detection circuit is a on-signal, that is, the state detection circuit changes from an off state to an on state, and the electronic cigarette determines that the installation signal of the cigarette cartridge is detected or that the cigarette cartridge is in an installed state; when the cigarette cartridge is pulled out of the battery device, the cigarette cartridge no longer presses the ejector pin or the ejector rod, the external force of the ejector pin or the ejector rod on the switch button is removed, the deformation of the elastic element in the switch element is restored, the switch button is reset, and the state detection circuit is disconnected. At this time, the on-off signal of the state detection circuit is a disconnection signal, that is, the state detection circuit changes from an on state to an off state, and the electronic cigarette detects the separation signal of the cigarette cartridge.

[0234] When the separation signal is detected, the electronic cigarette controls the heating element to work to remove the residue on the heating element. In actual implementation, the electronic cigarette controls the heating element to work according to the preset parameters, so as to remove the residue on the heating element. Among them, the preset parameters include one of the preset working voltage, the preset temperature and the preset power and the preset duration. The preset working voltage is greater than the working voltage when the electronic cigarette is in the suction state. The preset working voltage can also be equal to the current output voltage of the battery. The preset temperature is greater than the working temperature when the electronic cigarette is in the suction state. The working temperature is also the atomization temperature when the heating element is working normally. The preset power is greater than the working power when the electronic cigarette is in the suction state. The working power is also the atomization power when the heating element is working normally. By adopting a higher working voltage, working temperature or working power, the attached residue can be quickly consumed in a shorter time. For example, the preset working duration is a shorter duration, such as 1 second. Of course, in actual implementation, the heating element is controlled to work according to the corresponding working parameters when the electronic cigarette is in the suction state, and the residue on the heating element can also be removed.

[0235] Wherein, when the battery device is provided with a state detection circuit and a sensor, the control method of the electronic cigarette may further include the following steps:

[0236] When the cigarette cartridge is in an installed state, a third airflow signal of the sensor is obtained, wherein the sensor is arranged in a cavity on the battery device, and the cavity is connected to an airflow channel of the electronic cigarette;

[0237] If the third airflow signal is at a high level, the heating element is controlled to operate according to the corresponding operating parameters when the electronic cigarette is in the inhalation state.

[0238] When the on-off signal of the status detection circuit on the battery device is an on signal, the electronic cigarette confirms that the cartridge is in the installed state. At this time, it is determined whether the user is inhaling based on the airflow signal of the sensor. When the user inhales the electronic cigarette, there is airflow passing through the airflow channel of the electronic cigarette, and the airflow signal generated by the sensor is at a high level. At this time, the electronic cigarette controls the heating element to work according to the corresponding working parameters when the electronic cigarette is in the suction state, that is, controls the heating element to perform normal atomization. It should be understood that after detecting the separation signal of the cartridge being removed from the battery device, it indicates that the cartridge has been removed and is not installed. At this time, even if the third airflow signal is detected to be at a high level, the heating element is not controlled to work.

[0239] After controlling the heating element to work according to the corresponding working parameters when the electronic cigarette is in the inhalation state, the control method of the electronic cigarette may further include the following steps:

[0240] If the time duration for the resistance value of the heating element to rise to the preset resistance value is less than the preset time duration, the heating element is controlled to stop working;

[0241] If the time length during which the resistance value of the heating element rises to the preset resistance value is greater than or equal to the preset time length, the output power of the heating element is controlled so that the resistance value of the heating element is maintained at the preset resistance value.

[0242] Among them, the preset resistance value is the atomization resistance value when the electronic cigarette is performing atomization work, which is the normal working resistance value. Usually, an atomization temperature is set for the electronic cigarette when it leaves the factory. The atomization temperature corresponds to the resistance value of a heating element. When the electronic cigarette is working, the battery device outputs a voltage to the heating element to make the heating element 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 so that the resistance value of the heating element is stabilized at the resistance value, that is, the aforementioned atomization resistance value. Of course, the atomization resistance value can also be calculated according to the atomization temperature or power actually set by the user. During the heating process of the electronic cigarette, if the time when the resistance of the heating element rises to the preset resistance value is less than the preset time, it means that the heating element heats up too quickly due to dry burning. In order to protect the cigarette cartridge, the heating is stopped at this time; if the time when the resistance of the heating element rises to the preset resistance value is greater than or equal to the preset time, it means that the heating element is working normally. At this time, the output power of the heating element is controlled so that the resistance of the heating element is stabilized at the preset resistance value. Resistance stability means that the deviation of the resistance of the heating element relative to the preset resistance value is within a smaller range.

[0243] In one embodiment, the electronic cigarette control method may further include the following steps:

[0244] Controlling the heating element to work according to the received preset operation signal to remove the residue on the heating element;

[0245] During the operation of the heating element, the resistance change rate of the heating element is obtained;

[0246] If the resistance change rate is less than the preset change rate, control the heating element to stop working;

[0247] If the resistance change rate is greater than or equal to the preset change rate, control the heating element to work to remove the residues on the heating element.

[0248] Wherein, a self-cleaning manual button is further provided at the bottom of the electronic cigarette. When the manual button is pressed, a preset operation signal for controlling the heating element to work is generated, and the heating element starts to heat for self-cleaning. The preset change rate refers to the resistance change rate when the heating element works to remove residues under the condition of not installing a cartridge. When the heating element works with preset parameters to remove residues, the preset change rate refers to the resistance change rate when the heating element works with preset parameters under the condition of not installing a cartridge. During the self-cleaning process, if the cartridge is still inserted into the electronic cigarette, the resistance change rate of the heating element will be less than the preset change rate due to the attachment of more aerosol formation matrix. At this time, if the self-cleaning continues, the cartridge will be damaged. To ensure the integrity of the cartridge, control the heating element to stop working and stop self-cleaning. On the contrary, if the resistance change rate is greater than or equal to the preset change rate, it is considered that the heating element is not in contact with the aerosol formation matrix in the cartridge, and the residue cleaning can be carried out. At this time, continue to control the heating element to work.

[0249] For the control method of the electronic cigarette of the present invention, an aerosol formation matrix is stored in the cartridge of the electronic cigarette, and a heating element is provided on the battery device. The heating element is used to heat the aerosol formation matrix in the cartridge when powered on. When a separation signal indicating that the cartridge is removed from the battery device is detected, control the heating element to work to remove the residues on the heating element. In this way, the present invention can automatically clean the residues on the heating element for self-cleaning when the cartridge is removed from the battery device, thereby improving the service life of the heating element.

[0250] Figure 27 It is a schematic structural diagram of an electronic cigarette in an exemplary embodiment of the present invention. As Figure 27 shown, the present invention further 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 control method of the electronic cigarette as described above.

[0251] For the specific steps executed by the processor 320 in this embodiment, please refer to Figures 1 to 26 the description of the embodiments shown, and details will not be repeated here.

[0252] The present invention further provides a computer storage medium, on which computer program instructions are stored; when the computer program instructions are executed by a processor, the control method of the electronic cigarette as described above is implemented.

[0253] The aforementioned storage medium includes: various media that can store program codes, such as USB flash drives, external hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, optical discs, or cloud storage, etc.

[0254] For the specific step flow implemented when the computer program instructions stored in the computer storage medium of this embodiment are executed by the processor, please refer to Figures 1 to 26 the description of the illustrated embodiment, which will not be elaborated here.

[0255] Please refer to Figure 28 , which shows the method flowchart of the control method of an electronic cigarette provided by an embodiment of the present invention. As Figure 28 shown, the control method of the electronic cigarette may include:

[0256] Step 110, detecting whether the standby condition of the electronic cigarette is met.

[0257] This step can be implemented in the following two ways:

[0258] First, determining whether the electronic cigarette is operated; if the electronic cigarette has not been operated for a predetermined duration, it is determined that the standby condition of the electronic cigarette is met. Among them, the predetermined duration can be set by developers or customized by users.

[0259] Among them, the specific implementation of determining whether the electronic cigarette is operated can be: obtaining the operation information of the electronic cigarette, where the operation information includes lighting information and movement indication information; and determining whether the electronic cigarette is operated according to the operation information.

[0260] Among them, the lighting information is whether the electronic cigarette is lit, that is, whether the atomization component in the electronic cigarette performs atomization work; the movement indication information includes at least one of the acceleration information of the electronic cigarette, the liquid level height information in the liquid storage cavity of the electronic cigarette, and the liquid flow information of the e-liquid in the liquid storage cavity of the electronic cigarette;

[0261] Optionally, the specific implementation of determining whether the electronic cigarette is operated according to the lighting information can be: when no lighting signal is detected, it is determined that the electronic cigarette is not operated for suction; or, when atomization work is not performed according to the lighting signal, it is determined that the electronic cigarette is not operated for suction; or, if a lighting signal and a suction signal are detected, it is determined that the electronic cigarette is operated for suction, otherwise it is determined that the electronic cigarette is not operated for suction.

[0262] Among them, the ignition signal involved in this application can be a signal generated when the ignition button on the electronic cigarette is operated. The ignition signal can also be an air flow signal detected by a sensor component in the electronic cigarette. The air duct where the sensor component is located is connected to the mouthpiece of the electronic cigarette. When the user sucks through the mouthpiece of the electronic cigarette, since the sensor component is arranged in the air duct connected to the mouthpiece, the sensor component can detect the air flow change in the air duct, such as air pressure change, air flow velocity change, etc. The sensor component can be a sensor for detecting air flow such as a barometric pressure sensor, an air flow sensor, a pressure sensor, etc.

[0263] Optionally, when the ignition signal is not the air flow signal detected by the sensor component in the electronic cigarette, the suction signal can be the air flow signal detected by the sensor component in the electronic cigarette.

[0264] Optionally, the specific implementation of determining whether the electronic cigarette is operated according to the movement indication information can be: if it is determined according to the movement indication information that the electronic cigarette is stationary, it is determined that the electronic cigarette is not operated.

[0265] When the user holds the electronic cigarette and rotates or moves the electronic cigarette, the electronic cigarette generates acceleration, the liquid level in the liquid storage cavity shakes, and the e-liquid in the liquid storage cavity will flow. In this application, the electronic cigarette can obtain the movement indication information of the electronic cigarette; and determine whether the electronic cigarette is stationary or shaking according to the movement indication information.

[0266] Among them, determining whether the electronic cigarette is stationary according to the movement indication information can be implemented in any of the following ways: 1. If the acceleration of the electronic cigarette is lower than or equal to a predetermined threshold, it is determined that the electronic cigarette is not operated; 2. If the change value of the liquid level height in the liquid storage cavity is lower than or equal to a predetermined threshold, it is determined that the electronic cigarette is not operated; 3. If the flow velocity of the e-liquid in the liquid storage cavity is lower than or equal to a predetermined threshold, it is determined that the electronic cigarette is not operated. Among them, the predetermined threshold is usually set by the developer.

[0267] In this application, the detection of the liquid level height can be detected by setting a liquid level detector in the liquid storage cavity. The acceleration detection of the electronic cigarette can be detected by a gyroscope or other acceleration detection components in the electronic cigarette. The flow velocity of the e-liquid in the liquid storage cavity can be detected by a flow velocity detection device in the liquid storage cavity. This application does not make specific limitations on the height detection method, the acceleration detection method, and the detection method of the e-liquid flow information.

[0268] Second, detect whether a standby instruction is received; if a standby instruction is received, it is determined that the standby condition of the electronic cigarette is met. Among them, the standby instruction can be a standby instruction generated by operating the child lock key on the electronic cigarette, the standby instruction can also be a standby instruction generated by knocking the electronic cigarette, and the standby instruction can also be others, which will not be elaborated one by one in this implementation.

[0269] Optionally, the specific implementation of detecting whether a standby instruction is received may be: obtaining the tapping information of the electronic cigarette; determining whether a standby instruction is received according to the tapping information. Optionally, a 3D sensor may be provided in the electronic cigarette, and the data detected by the 3D sensor can be used to determine whether the electronic cigarette is tapped to obtain the tapping information; when the tapping information of the electronic cigarette indicates that the electronic cigarette is continuously tapped up to a second predetermined number of times, it is determined that a tapping instruction is received, and the second predetermined number of times can be set by the developer or customized by the user.

[0270] Step 120, if the standby condition of the electronic cigarette is satisfied, control the electronic cigarette to enter the standby state.

[0271] Step 130, when the electronic cigarette is in the standby state and a smoking signal is detected, the electronic cigarette stops controlling the atomization component to perform atomization work according to the smoking signal.

[0272] By controlling the electronic cigarette to enter the standby state, the electronic cigarette in the standby state stops controlling the atomization component to perform atomization work according to the smoking signal, so as to temporarily turn off the smoking function of the electronic cigarette.

[0273] For example, after the user of the electronic cigarette uses the electronic cigarette for suction and the electronic cigarette is left standing for a predetermined duration of 1 minute, control the electronic cigarette to enter the standby state, and the electronic cigarette stops performing atomization work according to the smoking signal; at this time, if a child grabs the electronic cigarette and accidentally touches the smoking button, since the electronic cigarette no longer performs atomization work according to the smoking signal, the atomized smoke is prevented from being accidentally inhaled by the child.

[0274] In summary, the method provided by the embodiment of the present invention detects whether the standby condition of the electronic cigarette is satisfied; if the standby condition of the electronic cigarette is satisfied, control the electronic cigarette to enter the standby state; when the electronic cigarette is in the standby state and a smoking signal is detected, the electronic cigarette stops controlling the atomization component to perform atomization work according to the smoking signal; solves the problem in the related art that a child grabs the electronic cigarette and accidentally touches the smoking button, and the atomized smoke of the electronic cigarette is inhaled by the child, damaging the physical and mental health of the child; achieves the effect of increasing the child protection function of the electronic cigarette.

[0275] After the electronic cigarette enters the standby state, the user of the electronic cigarette can generate an atomization wake-up signal by operating the electronic cigarette to activate the atomization function of the electronic cigarette. The specific implementation may be: when the electronic cigarette is in the standby state and an atomization wake-up signal is detected, control the electronic cigarette to enter the working state; when the electronic cigarette is in the working state and a smoking signal is detected, control the atomization component to perform atomization work according to the smoking signal.

[0276] In one example, an e-cigarette user can trigger the e-cigarette to enter the working state by removing and reinstalling a predetermined component from the e-cigarette. The specific implementation can be as follows: If, after detecting that a predetermined component inside the e-cigarette is removed, it is detected that any predetermined component is installed onto the main body of the e-cigarette, it is determined that an atomization wake-up signal is detected, and this predetermined component is an atomizer or a cartridge.

[0277] In one example, a probe or a push-button switch is provided on the mounting base. When the predetermined component is installed onto this mounting base, the predetermined component presses against the probe or presses the push-button switch; when the e-cigarette detects an operation signal generated by the probe being pressed against or the push-button switch being pressed, it is determined that the predetermined component is installed onto the main body of the e-cigarette.

[0278] In another example, a heating element is provided inside the predetermined component. When the predetermined component is installed onto the mounting base, this heating element is connected to the load access circuit inside the main body of the e-cigarette; when the e-cigarette detects that there is a load accessing the load access circuit, it is determined that the predetermined component is installed onto the main body of the e-cigarette.

[0279] In yet another example, a magnetic component is provided inside the predetermined component, and a Hall switch is provided on the mounting base. When the predetermined component is installed onto the mounting base, the Hall switch detects the magnetic component; the e-cigarette detects whether the predetermined component is installed onto the mounting base through the Hall switch. In actual implementation, this magnetic component can be a magnetic ring or a circular magnetic sheet provided at the bottom or the lower end of the cartridge.

[0280] Optionally, a receiving cavity for the predetermined component is provided on the main body of the e-cigarette, and a mounting base for the predetermined component is provided inside the receiving cavity; the e-cigarette user can install the predetermined component onto the main body of the e-cigarette by inserting the predetermined component into this receiving cavity; the e-cigarette can also separate the predetermined component from the main body of the e-cigarette by pulling the predetermined component out of the receiving cavity. In this embodiment, the e-cigarette user can trigger the e-cigarette to enter the working state by pulling the predetermined component out of the receiving cavity and then inserting it.

[0281] In another embodiment, the e-cigarette user can trigger the e-cigarette to enter the standby state by pulling the predetermined component out of the receiving cavity; and then trigger the e-cigarette to enter the working state by inserting the predetermined component into the receiving cavity. The specific implementation can be as follows: When it is detected that the predetermined component is separated from the main body of the e-cigarette, it is determined that a standby instruction is received, and the e-cigarette is controlled to enter the standby state according to this standby instruction; when it is detected that the predetermined component is installed onto the main body of the e-cigarette, it is determined that an atomization wake-up signal is detected, and the e-cigarette is controlled to enter the working state according to this atomization wake-up signal.

[0282] In another example, when the e-cigarette meets the standby condition, the e-cigarette is controlled to enter the standby state, and a predetermined component in the e-cigarette is controlled to be separated from the main body of the e-cigarette. The predetermined component is an atomizer or a cartridge. In this way, the user of the e-cigarette can reinstall the predetermined component to the main body of the e-cigarette, for example, insert the predetermined component into the mounting base of the corresponding accommodating cavity; when the e-cigarette detects that the predetermined component is installed to the main body of the e-cigarette, the e-cigarette is controlled to enter the working state; and if a smoking signal is detected, the atomization component is controlled to perform atomization work.

[0283] Taking the cartridge as an example, a receiving cavity for the cartridge is provided on the main body of the e-cigarette, and a mounting base for the cartridge is provided in the receiving cavity; a pushing member may be provided on the mounting base, and when the e-cigarette meets the standby condition, the pushing member is driven to push the cartridge so that the cartridge is separated from the mounting base.

[0284] In yet another example, when the e-cigarette meets the standby condition, the e-cigarette is controlled to enter the standby state, and a predetermined component in the e-cigarette is controlled to rotate around the central axis of the predetermined component, so that a first component in the predetermined component is separated from or moved away from a second component on the main body of the e-cigarette; wherein, the predetermined component is an atomizer or a cartridge, and the e-cigarette does not have atomization ability when the first component is separated from or moved away from the second component. In this way, the user of the e-cigarette can then operate the predetermined component to rotate and reset around the central axis of the predetermined component. When the e-cigarette detects that the predetermined component is reset, it is determined that an atomization wake-up signal is detected.

[0285] In yet another example, the user of the e-cigarette can trigger the e-cigarette to enter the working state by rotating and then resetting the predetermined component. The specific implementation can be: after the e-cigarette detects that the first component is separated from or moved away from the second component on the main body of the e-cigarette, if it detects that the predetermined component rotates to a predetermined position (that is, resets), it is determined that an atomization wake-up signal is detected, and the e-cigarette has atomization ability when the predetermined component rotates to the predetermined position.

[0286] Optionally, the user of the e-cigarette can trigger the e-cigarette to enter the working state by rotating the predetermined component. The specific implementation can be: when the e-cigarette is in the standby state, it detects whether the predetermined component in the e-cigarette is rotated, and the predetermined component is an atomizer or a cartridge; if it detects that the predetermined component is rotated to a predetermined position, it is determined that an atomization wake-up signal is detected. Optionally, when the e-cigarette detects that the first component is separated from or moved away from the second component on the main body of the e-cigarette, it determines that a standby instruction is received and enters the standby state, so that the user can trigger the e-cigarette to enter the standby state by rotating the predetermined component.

[0287] Optionally, the first component and the second component in the e-cigarette can be set in the following ways:

[0288] First, the first component is the electrode on the cartridge, and the second component is the electrode on the e-cigarette body; when the first component is connected to the second component, the battery component in the e-cigarette body can supply power to the atomization component (e.g., the heating element) in the predetermined component through the first component and the second component for atomization work. When the e-cigarette meets the standby condition, it can control the predetermined component to rotate around the central axis of the predetermined component, so that the electrode on the predetermined component is separated from the electrode on the e-cigarette body, so as to realize that when the e-cigarette detects a smoking signal, it stops atomizing according to the smoking signal.

[0289] Second, the first component is the liquid storage cavity in the predetermined component, and a heating element and a liquid guiding element are arranged on the e-cigarette body, and the liquid guiding element is the second component; both ends of the liquid guiding element can extend into the liquid storage cavity. When both ends of the liquid guiding element extend into the liquid storage cavity, the liquid guiding element can absorb the e-liquid in the liquid storage cavity. When the e-cigarette controls the heating element to heat according to the smoking signal, it can atomize the e-liquid on the liquid guiding element; when the e-cigarette meets the standby condition, it can control the predetermined component to rotate around the central axis of the predetermined component, so that the liquid guiding element is separated from the liquid storage cavity, and the liquid guiding element stops absorbing e-liquid continuously, so as to realize that when the e-cigarette detects a smoking signal, it stops atomizing according to the smoking signal.

[0290] Third, the first component is the liquid absorbing element in the predetermined component, and the liquid absorbing element is used to absorb the e-liquid in the liquid storage cavity of the predetermined component, and the second component is the heating element; when the liquid absorbing element and the heating element are close, the liquid absorbing element absorbs the e-liquid in the liquid storage cavity, and the heating element heats up to atomize the e-liquid on the liquid absorbing element; when the e-cigarette meets the standby condition, it can control the predetermined component to rotate around the central axis of the predetermined component, so that the liquid absorbing element is far away from the heating element, so as to avoid atomizing the e-liquid on the liquid absorbing element when the heating element heats up, and realize that when the e-cigarette detects a smoking signal, it stops atomizing according to the smoking signal.

[0291] Optionally, a magnetic part can be arranged on the predetermined component, and a Hall switch can be arranged on the mounting base; the user of the e-cigarette can rotate the predetermined component to keep the magnetic part at a preset distance from or away from the Hall switch. When the predetermined component is rotated to the reset position, the Hall switch can detect the magnetic part, and when the predetermined component leaves the reset position, the Hall switch cannot detect the magnetic part; the e-cigarette detects whether the predetermined component is rotated to the reset position through the Hall switch; in actual implementation, other methods can also be used to determine whether the predetermined component is rotated to the reset position, which will not be elaborated one by one in this embodiment.

[0292] It should be noted that: in this application, by controlling the rotation of the predetermined component in the e-cigarette around the central axis of the predetermined component, the first component in the predetermined component is separated from or away from the second component on the e-cigarette body; in actual implementation, the first component and the second component can also be separated or away from each other in other ways, such as driving the first component to move and change positions, or driving the second component to move and change positions, which will not be elaborated one by one in this embodiment.
