[0171] The present invention will now 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, and therefore only shows the components related to the present invention.

[0172] See also Figure 1 , Figure 2 The present invention provides an electronic cigarette, which includes a cartridge 10 and a battery device 20 matched with the cartridge 10, and the cartridge 10 and the battery device 20 are detachably connected. The electronic cigarette also includes an atomizer. When in use, the battery device 20 supplies power, and the atomizer atomizes the aerosol-forming matrix stored in the cartridge 10 under the electric drive of the battery device 20, and the aerosol-forming matrix forms smoke under the atomization action, and the smoke is inhaled by the user. The atomizer can be at least one of a microwave heating device, an infrared heating device, an electromagnetic induction heating device, an ultrasonic atomizer, and a resistance heating device. The atomizer can be arranged on the cartridge 10, can be arranged on the battery device 20, or can be independently arranged relative to the cartridge 10 and the battery device 20. When the atomizer is arranged on the battery device 20, or is independently arranged relative to the cartridge 10 and the battery device 20, the atomizer is not involved when the user replaces the cartridge 10, which can reduce the replacement cost of the user. The aerosol-forming substrate may be tobacco liquid, tobacco shreds or tobacco paste. When the types of aerosol-forming substrates are different, the structure of the cigarette cartridge 10 is also different. For example, when the aerosol-forming substrate is tobacco shreds, the cigarette cartridge 10 may be configured to have a structure similar to that of an ordinary cigarette. In this embodiment, the aerosol-forming substrate is tobacco liquid as an example.

[0173] See also Figure 4 , Figure 7 and Figure 8 The cigarette cartridge 10 includes a sealing member 14, a mouthpiece 13 provided with a smoke outlet 131, a cigarette cartridge housing 16, a sealing pad 162, a liquid absorbing member 17, a liquid absorbing member support 18, and a base 15. The mouthpiece 13 is mounted on the upper end of the cigarette cartridge housing 16, the sealing pad 162 is disposed on the upper end of the cigarette cartridge housing 16 and is located between the mouthpiece 13 and the cigarette cartridge housing 16, a portion of the sealing member 14 is sequentially inserted into the interior of the cigarette cartridge housing 16 via the mouthpiece 13 and the sealing pad 162, another portion of the sealing member 14 is exposed to the exterior of the cigarette cartridge 10, the liquid absorbing member 17 and the liquid absorbing member support 18 are disposed in the lower end of the cigarette cartridge housing 16, and the base 15 is connected to the lower end of the cigarette cartridge housing 16. An atomization chamber 151, an air inlet 152 and a matching portion 153 are provided on the base 15. The air inlet 152 and the matching portion 153 are respectively located on opposite sides of the atomization chamber 151. When the cigarette cartridge 10 is installed on the battery device 20, the matching portion 153 and the battery device 20 form a specific matching structure for detecting whether the cigarette cartridge 10 is installed on the battery device 20 and whether the cigarette cartridge 10 is removed from the battery device 20.

[0174] 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, and 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.

[0175] In a specific embodiment, the absorbent support 18 is generally a hollow box-shaped structure with through holes at both ends, and the absorbent 17 is installed in the inner cavity of the absorbent support 18. A plurality of bending portions 181 for bending are provided on the side wall of the absorbent support 18 around the through hole at the upper end of the absorbent support 18. When installing, the absorbent 17 is placed in the inner cavity of the absorbent support 18 so that the lower surface of the absorbent 17 fits with the bottom wall of the absorbent support 18, and then the bending portion 181 is bent at a certain angle and pressure is applied downward so that the bending portion 181 fits with the upper surface of the absorbent 17, thereby fixing the absorbent 17 on the absorbent support 18. The operation is simple and convenient, and the automatic installation of the absorbent 17 can be realized. In this embodiment, the absorbent member 17 is cotton. It is understandable that in other embodiments not shown, the absorbent member 17 can also be a fiber rope, porous ceramics or porous graphite or other elements with absorbent ability, which is not limited here.

[0176] Please further combine Figure 4 , Figure 7 and Figure 8In this embodiment, the sealing member 14 includes an operating portion 141 and a sealing portion (not shown in the figure). One end of the operating portion 141 extends to the outside of the cigarette cartridge 10 and can be operated by the user. The other end of the operating portion 141 passes through the operating portion through-hole 163 and extends into the liquid storage chamber 19. The portion of the operating portion 141 located in the operating portion through-hole 163 seals the operating portion through-hole 163 to prevent leakage of the smoke liquid. The sealing portion includes a first sealing portion 142 and a second sealing portion 143 which are connected to each other. One end of the first sealing portion 142 is connected to one end of the operating portion 141 located in the liquid storage chamber 19, and the other end of the first sealing portion 142 is connected to the second sealing portion 143. A transverse notch 145 is provided at the connection between the first sealing portion 142 and the operating portion 141. The second sealing portion 143 is used to seal the liquid outlet 191. When the operating portion 141 moves outward along the operating portion through hole 163 under the action of external force, it drives the first sealing portion 142 to move upward along the axial direction of the cigarette cartridge 10, and the first sealing portion 142 drives the second sealing portion 143 to open the liquid outlet 191. The radial width of the second sealing portion 143 is greater than the aperture of the operating portion through-hole 163. When the operating portion 141 is continuously pulled upward along the axial direction of the cigarette cartridge 10 until the second sealing portion 143 abuts against the lower end surface of the sealing pad 162, the sealing member 14 cannot continue to move upward, and the first sealing portion 142 is inserted into the operating portion through-hole 163 to seal the operating portion through-hole 163. Since the connection between the first sealing portion 142 and the operating portion 141 has a transverse notch 145, the operating portion 141 and the first sealing portion 142 can be disconnected under the action of an external force, so that the operating portion 141 is separated from the first sealing portion 142 and taken out, and the first sealing portion 142 seals the operating portion through-hole 163, and will not destroy the sealing of the upper end of the liquid storage chamber 19. In addition, the through hole on the mouthpiece 13 for inserting the sealing member 14 serves as the smoke outlet 131 after the operating portion 141 is taken out. In this embodiment, a sealing strip 1421 is provided on the outer wall of the first sealing portion 142 along the radial direction of the first sealing portion 142, and the sealing strip 1421 is tightly fitted with the hole wall of the operating portion through hole 163, thereby improving the sealing of the liquid storage chamber 19. The movement stroke of the seal 14 (the movement distance of the second sealing portion 143 from the liquid outlet 191 to the movement distance of the second sealing portion 143 against the lower end surface of the sealing pad 162) is 5-50mm. In a specific embodiment, the movement stroke of the seal 14 is 10-15mm. If the movement stroke is too short, it means that the axial length of the liquid storage chamber 19 is too short. In this case, the volume of the liquid storage chamber 19 may be too small. If the movement stroke is too long, it will be inconvenient for the user to operate.

[0177] In addition, when the sealing member 14 is pulled, the sealing member 14 is deformed under the action of the pulling force, so that a gap is formed between the operating portion 141 and the hole wall of the operating portion through hole 163, and the external air can enter the liquid storage chamber 19 through the gap, so that the smoke liquid in the liquid storage chamber 19 flows out from the liquid outlet 191 and contacts with the liquid absorbing member 17, and is then absorbed by the liquid absorbing member 17. Otherwise, negative pressure will be formed in the liquid storage chamber 19, which is not conducive to the outflow of smoke liquid. At the same time, the liquid absorbing member 17 is located between the upper end opening of the atomization chamber 151 and the liquid outlet 191. Since the liquid absorbing component 17 is arranged directly below the liquid outlet 191, when the liquid outlet 191 is opened, the smoke liquid in the liquid storage chamber 191 can be absorbed by the liquid absorbing component 17 after flowing out from the liquid outlet 191, thereby shortening the flow distance of the smoke liquid. In actual use, the size of the liquid outlet 191 can be set slightly larger, as long as the size of the liquid outlet 191 matches the size of the liquid absorbing component 17. In this way, the smoke liquid can be quickly absorbed by the liquid absorbing component 17, shortening the waiting time for the liquid absorbing component 17 to absorb the smoke liquid after the user takes out the operating part 141, so that the user can use the electronic cigarette quickly.

[0178] In this embodiment, the atomization device is arranged on the battery device 20, and the atomization device is a resistance heating device, specifically, the atomization device is a heating element 21. The size of the lower end opening of the atomization chamber 151 matches the size of the heating element 21. When the cigarette cartridge 10 is installed on the battery device 20, the heating element 21 arranged on the battery device 20 extends from the lower end opening of the atomization chamber 151 into the atomization chamber 151, and contacts or maintains a preset distance from the liquid absorbing element 17. The heating element 21 can generate heat to heat the smoke liquid on the liquid absorbing element 17 under the action of electric drive, and the smoke liquid is heated to form smoke. When the user uses it, the smoke generated by the atomized smoke liquid in the atomization chamber 151 flows out through the airflow channel 165 and the smoke outlet 131. When the smoke liquid in the liquid storage chamber 19 is exhausted, the user can replace a new cigarette cartridge 10. Since the heating element 21 is arranged on the battery device 20, the replacement of the cigarette cartridge 10 does not involve the heating element 21, which reduces the replacement cost of the cigarette cartridge 10. In addition, the caliber of the lower opening of the airflow channel 165 is larger than the caliber of the upper opening of the airflow channel 165, so that the suction pressure at the lower opening of the airflow channel 165 is smaller, preventing large particles of smoke liquid from being sucked out. In addition, the channel wall at the lower end of the airflow channel 165 is set to an arc surface, making the connection smoother, the smoke encounters less obstacles, and it is not easy to produce condensate. Specifically, one side of the cavity wall of the liquid storage chamber 19 and one side of the channel wall of the airflow channel 165 are the same wall body (not marked in the figure). The lower end of the wall body and the other cavity walls of the liquid storage chamber 19 are enclosed to form a liquid outlet 191, the upper end of the wall body and the other channel walls of the airflow channel 165 are enclosed to form the upper opening of the airflow channel 165, the lower end of the wall body and the other channel walls of the airflow channel 165 are enclosed to form the lower opening of the airflow channel 165, and the lower end of the wall body is bent toward the liquid storage chamber 19, so that the caliber of the upper opening of the airflow channel 165 is smaller than the caliber of the lower opening of the airflow 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 inwards to prevent the smoke liquid in the liquid storage chamber 19 from flowing out through the liquid outlet 191 too quickly.

[0179] In addition, the electronic cigarette of the present invention adopts an isolation structure. Specifically, before using the electronic cigarette, the smoke liquid in the liquid storage chamber 19 is isolated from the liquid absorbing member 17 by the isolation structure, so that the smoke liquid is kept in the liquid storage chamber 19. When it is needed, the liquid storage chamber 19 is opened, so that the smoke liquid in the liquid storage chamber 19 flows to the liquid absorbing member 17 and is then absorbed by the liquid absorbing member 17. In this way, the storage and transportation of the cigarette cartridge 10 are convenient. Moreover, it can effectively prevent the liquid absorbing member 17 from absorbing part of the smoke liquid before contacting the heating member 21, thereby preventing the situation that the heating member 21 squeezes the liquid absorbing member 17 and squeezes out the smoke liquid absorbed on the liquid absorbing member 17 when the cigarette cartridge 10 is installed, thereby avoiding the leakage of smoke liquid. It can be understood that when the liquid absorbing member 17 is made of a hard material such as porous ceramics, an isolation structure may not be set between the liquid storage chamber 19 and the liquid absorbing member 17, and the liquid absorbing member 17 will not be deformed under the squeezing of the heating member 21, so that the smoke liquid on the liquid absorbing member 17 will not be squeezed out. It is understandable that in other embodiments not shown, in addition to using the seal 14 as an isolation structure, other isolation structures may also be used, such as a puncturable sealing membrane or a movable sealing plate, and the liquid storage chamber 19 may be opened by piercing the sealing membrane or the movable sealing plate.

[0180] Please refer again Figure 7 , Figure 8 , the base 15 is located in the receiving portion, and the base 15 is clamped with the cartridge housing 16. In order to ensure the sealing 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, and a mounting portion 166 is protruded downwardly from the upper end opening of the atomization chamber 151 on the upper end surface of the base seal 161, and the lower end opening of the mounting portion 166 is provided, and the liquid absorbent member 17 is installed on the liquid absorbent member bracket 18, and the liquid absorbent member 17 together with the liquid absorbent member bracket 18 are accommodated in the mounting portion 166 after passing through the lower end opening of the mounting portion 166. A liquid through hole 167 connected to the liquid absorbent member 17 is provided at the upper end of the mounting portion 166, and when the liquid outlet 191 is opened, the liquid through hole 167 is also connected to the liquid outlet 191. In addition, the upper end surface of the base seal 161 is partially recessed downward to form a recessed groove 1611 connected to the liquid hole 167, and 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 matches the recessed groove 1611. The insertion portion 160 is inserted into the recessed groove 1611 to effectively prevent the leakage of the smoke liquid. At the same time, the cavity wall of the liquid storage chamber 19 that maintains a preset distance from the liquid outlet 191 is tilted, and the tilted cavity wall can guide the flow of the smoke liquid, which is conducive to the smooth outflow of the smoke liquid.

[0181] An air guide portion 168 is protruded upward on the upper end surface of the base seal 161, and the air guide portion 168 is inserted into the air flow channel 165 from the lower end opening of the air flow channel 165, thereby increasing the sealing performance of the air flow channel 165. An air guide groove 157 is provided on the base 15 corresponding to the air guide portion 168, and one end of the air guide groove 157 penetrates the upper end surface of the base 15 along the axial direction of the cigarette cartridge 10 and is connected to the air guide portion 168, and the other end of the air guide groove 157 penetrates the cavity wall of the atomization cavity 151 along the radial direction of the cigarette cartridge 10 and is connected to the atomization cavity 151. The smoke in the atomization cavity 151 flows out through the air guide groove 157, the air guide portion 168, the air flow channel 165 and the smoke outlet 131 in sequence. A connecting groove 155 is provided on the base 15 opposite to the air guide groove 157. One end of the connecting groove 155 penetrates the cavity wall of the atomization cavity 151 along the radial direction of the cigarette cartridge 10 and is connected with the atomization cavity 151. The other end of the connecting groove 155 penetrates the lower end surface of the base 15 along the axial direction of the cigarette cartridge 10 to form an air inlet 152. In this way, the air inlet 152 and the lower end opening of the atomization cavity 151 are arranged parallel to the axial direction of the cigarette cartridge 10, that is, the two are staggered in the axial direction of the cigarette cartridge 10, which can prevent the condensate formed by the smoke in the atomization cavity 151 from entering the air inlet 152, and further enters the battery device 20 through the air inlet 152, affecting the use of electronic components in the battery device 20. In addition, a partition 156 is provided in the connecting groove 155, and an air hole 1561 is provided on the partition 156. The air hole 1561 is connected to the air inlet 152 and the connecting groove 155 respectively. The aperture of the air hole 1561 is small, and it is difficult for the condensate to enter the air inlet 152 through the air hole 1561 under the action of surface tension. The air hole 1561 can also be provided on the cavity wall of the atomizing chamber 151. The air hole 1561 provided on the cavity wall of the atomizing chamber 151 is used to connect the atomizing chamber 151 and the connecting groove 155, and is used to prevent the condensate from entering the connecting groove 155.

[0182] In order to facilitate the injection of cigarette liquid into the liquid storage chamber 19, a groove 169 is provided on the upper end surface of the sealing gasket 162 on the opposite sides of the sealing member 14, and a connecting port (not shown in the figure) is provided on the opposite sides of the sealing member 14 on the mouthpiece 13. When injecting liquid, one of the connecting ports is used as the injection port, and the other connecting port is used as the exhaust port. The injection needle passes through the injection port and the groove 169 corresponding to the injection port in sequence, and then extends into the liquid storage chamber 19 to inject cigarette liquid into the liquid storage chamber 19. The exhaust needle passes through the exhaust port and the groove 169 corresponding to the exhaust port in sequence, and then extends into the liquid storage chamber 19 to discharge the gas in the liquid storage chamber 19 during the injection process. After the injection is completed, the injection needle and the exhaust needle are pulled out, and the sealing gasket 162 forms a self-seal at the position pierced by the injection needle and the exhaust needle without leaking liquid. The provision of the groove 169 can reduce the thickness of the sealing gasket 162, thereby facilitating the puncture of the injection needle and the exhaust needle. During the entire liquid injection process, the liquid absorbing member 17 and the liquid storage chamber 19 are always in a mutually isolated state, which can effectively prevent the smoke liquid from leaking through the liquid absorbing member 17, and can also prevent the air from disturbing the liquid absorbing member 17 and causing the position of the liquid absorbing member 17 to shift. When inhaling through the cigarette holder 13, the two connecting ports are used as the smoke outlet 131.

[0183] In addition, please combine Figure 5 , Figure 6A liquid collecting member 164 is also provided between the sealing pad 162 and the cigarette holder 13, and the liquid collecting member 164 is used to absorb large particles of smoke liquid or condensed liquid. Specifically, the inner end surface of the cigarette holder 13 is provided with a first connecting tube 132, a second connecting tube 133 and a third connecting tube 134, both ends of which are connected, in sequence along the axial direction of the cigarette cartridge 10, wherein the inner cavity of the first connecting tube 132 forms one of the connecting ports, the inner cavity of the third connecting tube 134 forms another connecting port, and the operating portion 141 of the sealing member 14 passes through the inner cavity of the second connecting tube 133. A plurality of reinforcing ribs 136 are also provided on the inner end surface of the cigarette holder 13 along the axial direction of the cigarette cartridge 10, and the liquid collecting member 164 is sandwiched between the reinforcing ribs 136 and at least one of the first connecting tube 132, the second connecting tube 133 and the third connecting tube 134. In this embodiment, there are two liquid collecting members 164, which are arranged opposite to each other. In a specific embodiment, the liquid collecting member 164 is cotton, which is relatively soft and can fully fit with the first connecting tube 132, the second connecting tube 133, the third connecting tube 134 and the reinforcing rib 136, which can effectively prevent condensed liquid or large particles of smoke liquid from entering the user's mouth through the liquid collecting member 164, which is conducive 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 a fiber rope, porous ceramics, porous graphite and other elements with liquid absorption capacity. In addition, the sealing gasket 162 is provided with a guide groove 1621 and an installation groove 1622 corresponding to the reinforcing rib 136. When the cigarette holder 13 is installed, the reinforcing rib 136 slides along the guide groove 1621 so that the reinforcing rib 136 is partially inserted into the installation groove 1622, thereby realizing the connection relationship between the cigarette holder 13 and the sealing gasket 162.

[0184] Please refer again Figure 4 , Figure 7, the mouthpiece 13 is sleeved on the outside of the upper end of the cartridge housing 16, and the mouthpiece 13 and the cartridge housing 16 are both flat structures, which can effectively prevent the cartridge 10 from rolling off the pressure-bearing plane (for example, the desktop). In addition, a snap-in protrusion 1601 is convexly provided on the opposite side wall of the cartridge housing 16, and a snap-in groove 1301 is provided on the side wall of the mouthpiece 13 corresponding to the snap-in protrusion 1601. The snap-in protrusion 1601 is snapped with the snap-in groove 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, the 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 shrinks inward on the side of the suction end that maintains a preset distance, and is arranged as an arc surface, which is ergonomic and has a good suction experience. When the cartridge 10 is installed in place, the suction end is located outside the battery housing 24. The cartridge shell 16 is made of a transparent or translucent material, and a notch 135 is provided on the portion of the mouthpiece 13 corresponding to the liquid storage chamber 19, so that the cartridge shell 16 is partially exposed through the notch 135, thereby forming a window through which the liquid storage chamber 19 can be observed, making it convenient for the user to observe the usage or remaining amount of the liquid.

[0185] The bottom of the cigarette cartridge 10 is covered with a dust cover (not shown) or the cigarette cartridge 10 is contained in a sealed bag (not shown) to prevent the liquid absorbent 17 from being contaminated before use, thereby affecting the use of the user.

[0186] See also Figures 9 to 13The battery device 20 includes a heating element 21, a conductive column 231 and a battery device body, and the battery device 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 net, a heating wire or a heating rod. Among them, when a heating sheet or a heating net is used, the contact area between the heating element 21 and the liquid absorbing element 17 is large and uniform, and the smoke liquid on the liquid absorbing element 17 can be uniformly heated to 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 be a ceramic heating sheet, which is sintered with tungsten slurry in aluminum nitride ceramic. The two are densely combined and the porosity is less than 1%, so that the heating element 21 can heat up quickly and the temperature distribution is uniform, but the type of the heating element 21 is not limited thereto. Aluminum nitride ceramic refers to a composition including aluminum nitride. At the same time, the composition of aluminum nitride ceramic can also include other substances, such as aluminum oxide. In addition to using aluminum nitride ceramics, the main body of the heating element 21 can also be made of other ceramic materials, such as aluminum oxide 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 holder 23 is arranged in the battery housing 24, and the battery 233 is arranged on the battery holder 23. The holder seal 22 is sleeved on the outside of the upper end of the battery holder 23 and fits tightly with the inner wall of the battery housing 24 to prevent the smoke liquid from leaking into the interior of the battery device 20 through the gap between the battery housing 24 and the battery holder 23. The conductive column 231 is arranged at the upper end of the battery holder 23 and extends into the holder seal 22. The conductive column 231 is used to electrically connect the heating element 21 and the battery 233. The holder seal 22 divides the inner cavity of the battery housing 24 into a receiving cavity 242 located above the holder seal 22 and an installation cavity 243 located below the holder seal 22. The battery holder 23, the battery 233 and the first control board 29 are all located in the installation cavity 243. A portion of the detection component 25 is located in the installation cavity 243, and the other portion is located in the receiving cavity 242. The heating element 21 is located in the receiving cavity 242. The two pins 211 of the heating element 21 pass through the bracket seal 22 and are inserted into the conductive column 231, so as to fix the heating element 21 and electrically connect it to the conductive column 231. The receiving cavity 242 protects the heating element 21 and prevents the heating element 21 from breaking when it hits a hard material 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, so as to prevent the user's fingers from touching the heating element 21, thereby preventing the residual heat of the heating element 21 and the heat generated during self-cleaning from scalding the user. Please refer to Fig.15 and Figure 3, buckles 241 are provided on the two opposite walls of the receiving chamber 242, and slots 11 are correspondingly provided on the opposite side walls of the cartridge housing 16. The buckles 241 cooperate with the 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, the cartridge 10 is partially accommodated in the receiving chamber 242, which can prevent the cartridge 10 from shaking arbitrarily, improve the installation stability of the cartridge 10, and shorten the overall length of the electronic cigarette. In addition, it should be noted that when the cartridge 10 is installed in place, the mouthpiece 13 is located outside the battery housing 24, so that the user can inhale. In addition, a slide groove 1612 is provided on the side wall of the cartridge housing 16 along the sliding direction of the buckle 241 relative to the slot 11. During the installation of the cartridge 10 and the battery device 20, the buckle 241 slides along the slide groove 1612, and then engages with the slot 11 after being disengaged from the slide groove 1612. The setting of the slide groove 1612 can guide the installation of the cigarette cartridge 10 and facilitate the operation.

[0187] When the cigarette cartridge 10 is connected to the battery device 20, the heating element 21 extends into and is located in the atomization chamber 151 to maintain a preset distance or contact the liquid absorbing element 17, and the liquid absorbing element 17 is used to supply smoke liquid to the heating element 21 for atomization. When the cigarette cartridge 10 is installed on the battery device 20, the matching portion 153 on the cigarette cartridge 10 contacts the detection component 25, and when the cigarette cartridge 10 is removed from the battery device 20, the matching portion 153 on the cigarette cartridge 10 is separated from the detection component 25. The detection component 25 is connected to the first control board 29, and the detection component 25 is used to generate a separation signal when it is separated from the matching portion 153. The first control board 29 is used to control the heating element 21 to work according to the separation signal and the preset parameters to remove the residue attached to the heating element 21. The detection component 25 is also used to generate a connection signal when it contacts the matching 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 residue attached to the heating element 21. The residue includes, but is not limited to, residual aerosol-forming matrix and carbonized materials produced at high temperatures. When the separation signal is detected, the self-cleaning mode is started. When it is actually implemented, the heating element 21 is controlled to work for a shorter time at a higher power. 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 when it is atomizing. Removing the residue on the heating element 21 can prevent the residue from affecting the use of the electronic cigarette. For example, when the residue is residual smoke liquid, the residual smoke liquid can be prevented from entering the installation cavity 243 and affecting the electronic components in the installation cavity 243. In addition, self-cleaning is performed after the cigarette cartridge 10 is removed to prevent the liquid absorbent 17 from being carbonized under the high temperature during self-cleaning.

[0188] Two implementations of the detection assembly 25 are provided below.

[0189] In the first embodiment, see Figures 20 to 27 , the detection assembly 25 includes a sensor seal 26, a first cavity 253, a second cavity 254, a first sensor 251 and a second sensor 252. The first cavity 253 and the second cavity 254 are arranged on one side of the battery holder 23 and keep 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 cavity 253 and the second cavity 254 respectively. The first sensor 251 is installed in the first part 261 and placed in the first cavity 253. The opening of the first cavity 253 is connected to the air inlet 152. The second sensor 252 is installed in the second part 262 and placed in the second cavity 254. The matching portion 153 is a sealing protrusion. The matching portion 153 is protruding downward on the lower end surface of the base 15 corresponding to the air guide groove 157. When the cigarette cartridge 10 is installed on the battery device 20, the matching portion 153 blocks the opening of the second cavity 254. The first sensor 251 and the second sensor 252 are respectively connected to the first control board 29 to transmit the airflow signal to the first control board 29. Through the matching structure of the battery bracket 23, the sensor seal 26 and the first control board 29, the first cavity 253 and the second cavity 254 can be disconnected from each other to avoid airflow interference. When the matching portion 153 opens the opening of the second cavity 254 as the cigarette cartridge 10 is removed, a negative pressure will be generated in the second cavity 254, so that the second sensor 252 detects the change in internal air pressure and generates a corresponding airflow signal, that is, a high-level signal. At the same time, since the user will not inhale the electronic cigarette when removing the cigarette cartridge 10, and the first cavity 253 remains connected to the outside, the air pressure in the first cavity 253 remains unchanged, and the first sensor 251 will not detect the airflow signal, that is, a low-level signal is generated. Therefore, when the cigarette cartridge 10 is removed, the airflow signal of the first sensor 251 is low and the airflow signal of the second sensor 252 is high. When the airflow signal of the first sensor 251 is low and the airflow signal of the second sensor 252 is high, it can be considered that the separation signal of the cigarette cartridge 10 being 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 airflow used for detection is different, which can be the flow rate of the airflow or the change in air pressure caused by the flow of the airflow. The first sensor 251 and the second sensor 252 generate airflow signals when detecting corresponding airflow related information.

[0190] After the separation signal is detected, the self-cleaning mode is started. The first control board 29 controls the heating element 21 to work according to the preset parameters to remove the residues attached to the heating element 21. In actual implementation, the heating element 21 is controlled to work for a shorter time at a higher power, for example, heating for 1 second. The power used for self-cleaning is higher than the power of the heating element 21 when atomizing. Removing the residue on the heating element 21 can prevent the residue from affecting the use of the electronic cigarette. For example, when the residue is residual smoke liquid, the residual smoke liquid can be prevented from entering the installation cavity 243 and affecting the electronic components in the installation cavity 243. In addition, self-cleaning is performed after the cigarette cartridge 10 is removed to prevent the liquid absorbent 17 from carbonizing under the high temperature during self-cleaning.

[0191] Please refer to the above Fig.23 as well as Figure 24 to Figure 27 The support seal 22 is provided with a socket 224 for inserting the pin of the heating element 21, an air inlet hole 222 connected to the opening of the first cavity 253, a through hole 223 connected to the opening of the second cavity 254, and an air inlet notch 221. The socket 224 is provided on the upper end surface of the support seal 22, and the air inlet hole 222 and the through hole 223 are located on opposite sides of the socket 224. The pin of the heating element 21 is inserted into the conductive column 231 after passing through the socket 224. The air inlet notch 221 is provided on the side wall of the support seal 22 to maintain a preset distance from the air inlet hole 222. The matching portion 153 of the cigarette cartridge 10 closes or opens the opening of the second cavity 254 through the through hole 223 connected to the opening of the second cavity 254. In addition, please combine Fig. 20 The side wall of the cartridge housing 16 is provided with an air inlet groove 12. The air inlet groove 12 on the cartridge 10 cooperates with the battery housing 24 of the battery device 20 to form an air inlet channel, 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 the smoke in the atomization chamber 151 flows out from the air guide groove 157, the air guide part 168, the air flow channel 165 and the smoke outlet 131. Please combine Fig.23A first vent 245 is provided on the battery housing 24, a second vent 236 is provided on the side wall of the upper end of the battery holder 23, the air inlet notch 221 is communicated with the first vent 245 and the second vent 236 respectively, and the second vent 236 is also communicated with the opening of the first cavity 253. Therefore, when the electronic cigarette is inhaled, external gas enters through the first vent 245, the air inlet notch 221 and the second vent 236, and when flowing through the opening of the first cavity 253, it takes away the air in the first cavity 253, and then flows out from the air inlet hole 222, the air inlet 152, the connecting groove 155, the atomizing cavity 151, the air guide groove 157, the air guide part 168, the air flow channel 165 and the smoke outlet 131, so that a negative pressure is generated in the first cavity 253, and the first sensor 251 detects the change in air pressure and generates a corresponding air flow signal, that is, a high level signal. At this time, the opening of the second cavity 254 is closed by the matching part 153, there is no change in the air pressure in the second cavity 254, and the second sensor 252 remains in the state of outputting a low-level signal. When the airflow signal of the first sensor 251 is at a high level and the airflow signal of the second sensor 252 is at a low level, it is considered that the atomization start signal is detected. After the atomization start signal is detected, 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 smoke liquid on the liquid absorption element 17. It can be understood that the external gas entering from the first vent 245 can also take away the smoke in the atomization cavity 151 after entering the atomization cavity 151.

[0192] It should be noted that when the user does not perform any suction or disassembly operation on the electronic cigarette, there is no change in the air pressure in the first cavity 253 and the second cavity 254, the first sensor 251 and the second sensor 252 are both kept 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 inhales the battery device 20, the air in the first cavity 253 and the second cavity 254 is sucked out, the first cavity 253 and the second cavity 254 are both negative pressure, the first sensor 251 and the second sensor 252 both generate high-level signals, and the heating element 21 does not work at this time, thereby preventing the heating element 21 from working in an abnormal state.

[0193] In order to prevent the condensation of smoke or the leakage of smoke liquid from entering the first cavity 253 and the second cavity 254, thereby affecting the operation of the first sensor 251 and the second sensor 252. Fig. 27 As shown, the upper end surface of the battery holder 23 is partially recessed downward to form a first receiving groove 237 and a second receiving groove 238. A connecting portion 239 is protruded upward along the axial direction of the battery device 20 on the bottom wall of the first receiving groove 237, and the connecting portion 239 is connected to the opening of the first receiving groove 237 and the first cavity 253 respectively. Fig.25A partition 229 is convexly provided on the upper end surface of the support seal 22. When the support seal 22 is installed in place, the air inlet 222 and the connecting portion 239 are located on opposite sides of the partition 229, that is, the air inlet 222 and the connecting portion 239 are staggered. Since the connecting portion 239 is convexly provided and the air inlet 222 and the connecting portion 239 are staggered, even if the condensed liquid of smoke or the leaked smoke liquid enters the battery device 20, it cannot enter the first cavity 253 through the air inlet 222 and the connecting 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 vent 245, the air inlet notch 221 and the second vent 236, and then flows out through the air inlet hole 222, the air inlet 152, the connecting groove 155, the atomizing chamber 151, the air guide groove 157, the air guide part 168, the air flow channel 165 and the smoke outlet 131. In this process, the air in the first cavity 253 is taken out by the external gas through the opening of the first cavity 253, the connecting part 239 and the first receiving groove 237, so that a negative pressure is generated in the first cavity 253. The first sensor 251 detects the change in air pressure and generates a corresponding air flow signal, that is, a high-level signal. It can be understood that in other embodiments not shown, a waterproof and breathable membrane can also be set at the opening of the first cavity 253, so that the air in the first cavity 253 can be smoothly sucked out, and the condensate or leaked smoke liquid and other liquids are isolated outside the first cavity 253 by the waterproof and breathable membrane. Alternatively, a deformable member is provided at the opening of the first cavity 253. Under the action of the user's suction, the deformable member is deformed, so that the space enclosed by the first cavity 253 and the deformable member becomes larger, and the air pressure in the space is reduced. The first sensor 251 detects the change in air pressure and generates a corresponding airflow signal. When the suction stops, the deformable member resumes its deformation and the air pressure in the space is restored. The deformable member isolates liquids such as condensed liquid or leaked smoke liquid outside the first cavity 253. In this embodiment, the detection component 25 also includes a deformable portion 225. The deformable portion 225 is formed by a downward protrusion of a portion 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 upper end opening. Please refer to the embodiment of the present invention in combination with the above. Fig.23When 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 respectively connected to the opening of the second cavity 254 and the second receiving groove 238. 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 deformation part 225 is deformed under the action of the matching part 153, and the enclosed space formed by the second cavity 254 and the deformation part 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 deformation part 225 separates the second sensor 252 in the second cavity 254 from the outside world, thereby preventing the condensed liquid or leaked smoke liquid from entering the second cavity 254 and affecting the normal operation of the second sensor 252.

[0194] 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.

[0195] A dual sensor structure is provided in the battery device 20, which can cooperate with the matching part 153 on the cigarette cartridge 10 to generate a signal when the cigarette cartridge 10 is removed, so that the electronic cigarette can automatically remove the residue on the heating element 21 when the cigarette cartridge 10 is removed, realize self-cleaning, and improve the service life of the heating element 21 and the electronic components in the battery device 10.

[0196] In the second embodiment, a mating portion 153 is formed on the side of the lower end surface of the base 15 opposite to the air inlet 152, and the detection assembly 25 includes a state detection circuit (not shown in the figure), which is used to detect the installation state of the cigarette cartridge 10. When the cigarette cartridge 10 is installed on the battery device 20, the state detection circuit cooperates with the mating portion 153 and is in a conducting state. When the cigarette cartridge 10 is removed from the battery device 20, the state detection circuit and the mating portion 153 are released and are in a disconnected state. The disconnection signal of the state detection circuit corresponds to the separation signal generated when the cigarette cartridge 10 is removed from the battery device 20. In this embodiment, a switch element 653 is provided in the state detection circuit. When the cigarette cartridge 10 is installed on the battery device 20, the mating portion 153 drives the switch element 653 to conduct the state detection circuit. When the cigarette cartridge 10 is removed from the battery device 20, the switch element 653 is separated from the mating portion 153 and reset, so that the state detection circuit is disconnected to generate a separation signal.

[0197] See also Fig.13In actual implementation, the switch element 653 includes an ejector pin 651 and a switch button 652. The battery device 20 is provided with an ejector pin installation through hole (not shown) on the installation side of the cartridge 10. The ejector pin 651 is inserted into the ejector pin installation through hole. The ejector pin 651 protrudes outside the bracket seal 62 and corresponds to the position of the matching portion 153 on the cartridge 10. The ejector pin 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 Corresponding to the position of the ejector pin 651, the switch button 652 is connected to an elastic element and can automatically reset after the external force is removed. When the cigarette cartridge 10 is installed on the battery device 20, the matching portion 153 presses the switch button 652 to the closed position through the ejector pin 651. When the cigarette cartridge 10 is removed from the battery device 20, the ejector pin 651 is reset under the action of the corresponding elastic element, and then the switch button 652 is reset to the disconnected position under the action of the corresponding elastic element. At this time, the state detection circuit is disconnected and a separation signal is generated. The elastic element connected to the ejector pin 651 can be omitted. In the process of the switch button 652 being reset to the disconnected position under the action of the corresponding elastic element, the switch button 652 can drive the ejector pin 651 to reset. The matching portion 153 that can push the ejector pin 651 can be a surface, groove or protrusion of the base 15 of the cigarette cartridge 10. It only needs to be able to press the ejector pin 651 down with the movement of the cigarette cartridge 10, and there is no limitation on the shape. It can be understood that the reset element that drives the ejector pin 651 and the switch button 652 to reset can be other elements besides the elastic element, for example, a magnetic element. Specifically, a pair of magnetic elements that repel each other are provided 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 ejector pin 651 presses the switch button 652, the repulsive force is overcome, so that the switch button 652 is pressed to the closed position.

[0198] It can be understood that the structure of the switch element 653 of the present embodiment is not limited thereto. For example, the switch element 653 is only a switch button, and the matching portion 153 provided on the cigarette cartridge 10 is a push rod. When the cigarette cartridge 10 is installed, the push rod on the cigarette cartridge 10 can press the switch button to the closed position. When the cigarette cartridge 10 is removed from the battery device 20, the push rod leaves the switch button, and the switch button is reset under the action of the corresponding elastic element to disconnect the state detection circuit. Alternatively, the switch element 653 is only a switch button, the top of which protrudes out of the outside of the bracket seal 22, and the matching portion 153 provided on the cigarette cartridge 10 is a plane or a groove. When the cigarette cartridge 10 is installed, the cigarette cartridge 10 can directly press the switch button to the closed position. When the cigarette cartridge 10 is removed from the battery device 20, the cigarette cartridge 10 leaves the switch button, and the switch button is reset under the action of the corresponding elastic element to disconnect the state detection circuit.

[0199] The battery device 20 is provided with a status detection circuit and a resettable switch element 653, which can cooperate with the matching part 153 on the cigarette cartridge 10 to generate a signal when the cigarette cartridge 10 is removed, so that the electronic cigarette can automatically remove the residue on the heating element 21 when the cigarette cartridge 10 is removed, realize self-cleaning, and improve the service life of the heating element 21 and the electronic components in the battery device 20.

[0200] In the above two embodiments, the mating part contacts the detection component when the cigarette cartridge is installed on the battery device, and separates from the detection component when the cigarette cartridge is removed from the battery device. The detection component is used to generate a separation signal when it is separated from the mating part, and generate a connection signal when it contacts the mating part. It can be understood that in other embodiments not shown, the mating part and the detection component can also adopt other mating methods, as long as the detection component generates a separation signal when the cigarette cartridge is removed from the battery device, and the detection component generates a connection signal when the cigarette cartridge is connected to the battery device. For example, the mating part and the detection component may not be in contact at all times. Specifically, the detection component includes a light source and a light sensor. When the cigarette 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. When the cigarette cartridge is removed, the light beam cannot be reflected, so that the light sensor detects that the light beam disappears, and the light sensor generates a separation signal.

[0201] Please refer again Fig.12 , Fig.13, a cavity 61 is provided in 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 and installed in the sensor seal 26 and placed in the cavity 61, the cavity 61 is connected to the mouthpiece 13, the sensor 66 is used to detect the airflow state in the cavity 61, when the air in the cavity 61 is sucked out under the suction action of the user so that a negative pressure is generated in the cavity 61, the sensor 66 generates an airflow signal, and the first control board 29 is used to control the heating element 21 to perform atomization according to the airflow signal. In this way, when the state detection circuit is turned on, the electronic cigarette confirms that the cigarette cartridge 10 is in the installed state, and at this time, it is determined whether the user performs a suction operation according to the airflow signal of the sensor 66. When the user inhales the electronic cigarette, the air in the cavity 61 is sucked out, the cavity 61 is in a negative pressure state, and the airflow signal generated by the sensor 66 is 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 energized and then performs atomization. It should be noted that after the first control board 29 receives the separation signal of the cigarette cartridge 10 being removed from the battery device 20, it indicates that the cigarette cartridge 10 has been removed. At this time, even if the airflow signal is detected to be high, the first control board 29 will not control the battery 233 to supply power to the heating element 21, that is, the heating element 21 cannot perform atomization, which can effectively play a child protection function to prevent the battery device 20 from being triggered by mistake when only the opening of the battery device 20 is sucked. In this embodiment, the sensor 66 is an airflow sensor for generating an airflow signal when the airflow flows. It can be understood that in other embodiments not shown, the sensor 66 is an air pressure sensor for generating an airflow signal when the airflow flows out to generate a negative pressure in the cavity 61. It can be understood that when the type of sensor 66 is different, the relevant information of the airflow used for detection is different, which can be the flow rate of the airflow or the air pressure change caused by the airflow. The sensor 66 generates an airflow signal when detecting the relevant information of the corresponding airflow. It can be understood that the above-mentioned airflow signal constitutes a suction signal, that is, when the detection component 25 generates a connection signal and the sensor 66 generates a suction signal, the first control board 29 controls the battery 233 to supply power to the heating element 21, so that the heating element 21 performs atomization.

[0202] See also Fig.10 , Fig.11, a convex column 226 is formed at the center of the upper end surface of the support seal 22, extending upward along the axial direction of the support seal 22, and the top of the convex column 226 is recessed downward to form a liquid collecting tank 2211. The top of the liquid collecting tank 2211 is provided with two plug holes 224 that penetrate the upper and lower end surfaces of the support seal 22. The two pins 211 of the heating element 21 are respectively connected to the corresponding conductive columns 231 after passing through the plug holes 224 and electrically conducting. During actual use, the condensate generated when the smoke is cooled can be collected in the liquid collecting tank 2211 to prevent the condensate from entering the interior of the battery device 20 and causing damage to other components. In addition, the liquid collecting tank 2211 is arranged to maintain a preset distance from the heating element 21. The heat generated by the heating element 21 after being energized can atomize the condensate in the liquid collecting tank 2211, thereby achieving a cleaning effect on the condensate in the liquid collecting tank 2211. It should also be noted that when the cigarette cartridge 10 is installed in place, the boss 226 is inserted into the atomization chamber 151, and the cavity wall of the atomization chamber 151 fits with the outer surface of the boss 226. In this way, the condensed liquid in the atomization chamber 151 can only enter the liquid collecting tank 2211 and will not leak to other places.

[0203] An air inlet notch 221 is provided on the upper end surface of the support seal 22 at one side of the protruding column 226, and the air inlet notch 221 corresponds to the air inlet port 152. A vent 245 is provided on the side wall of the battery housing 24, and the vent 245 is connected to the outside atmosphere and the air inlet notch 221. An induction tube 2212 is convexly provided on the upper end surface of the battery support 23, and the induction tube 2212 is a tubular structure with two ends connected. The inner cavity of the induction tube 2212 forms an induction channel 2213, and the lower end of the induction channel 2213 is connected to the cavity 61. The upper end of the induction tube 2212 passes through the support seal 22 and extends into the air inlet notch 221. When the cigarette cartridge 10 and the battery device 20 are installed in place, the air inlet notch 221 and the sensing channel 2213 are both connected to the air inlet 152. When the user inhales the electronic cigarette, the external gas enters the air inlet notch 221 through the vent 245, and when it flows through the upper port of the sensing channel 2213, it takes away the air in the cavity 61, and then flows out from the air inlet 152, the connecting groove 155, the atomizing cavity 151, the air guide groove 157, the air guide part 168, the air flow channel 165 and the smoke outlet 131, so that negative pressure is generated in the cavity 61, and 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 atomization. The external gas flows into the atomizing cavity 151 and can carry smoke to flow out from the air guide groove 157, the air guide part 168, the air flow channel 165 and the smoke outlet 131 for the user to inhale. In addition, a waterproof breathable membrane (not shown) can be installed at the upper opening of the sensing tube 2212, so that the condensate cannot enter the cavity 61 and thus prevent the condensate from contacting the sensor 66, while the air in the cavity 61 can be smoothly sucked, so that the sensor 66 detects the relevant information of the airflow. It can be understood that the waterproof breathable membrane can also be set at other positions, as long as the sensor 66 is isolated from the air inlet 152. For example, the waterproof breathable membrane can be set in the cavity 61, or in the sensing channel 2213. It can be understood that in other embodiments not shown, a deformable member can also be set corresponding to the opening of the cavity 61, and the sensor 66 is located in the space enclosed by the deformable member and the cavity 61. When the user inhales, the deformable member is deformed, the volume of the space increases, and the air pressure in the space decreases. The sensor 66 detects the change in air pressure and generates a corresponding airflow signal. When the inhalation stops, the deformable member resumes the deformation and the air pressure in the space is restored. The deformable member isolates the condensate or leaked smoke liquid and other liquids outside the cavity 61.

[0204] Please refer again Figure 2In this embodiment, the opening of the battery housing 24 is set as an oblique opening, and one of the surfaces of the cigarette holder 13 is correspondingly set as an inclined surface. When the cigarette cartridge 10 and the battery device 20 are installed in place, the oblique opening of the battery housing 24 and the inclined surface of the cigarette holder 13 cooperate with each other. In this way, when the cigarette cartridge 10 is installed, the cigarette cartridge 10 can only be inserted into the receiving cavity 242 in a single direction, ensuring that after the cigarette cartridge 10 is inserted, the sensing channel 2213 can correspond to the air inlet 152. Specifically, the battery housing 24 has a first end (not shown) and a second end (not shown) that are relatively arranged. The second end is an open end, and the cigarette cartridge 10 is detachably inserted into the battery housing 24 through the open end. In order to prevent the user from arbitrarily contacting 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 caliber of the open end is small, making it difficult for the user's fingers to be inserted, thereby preventing the user from contacting the heating element 21. The battery housing 224 has a first limiting portion (not shown) and a second limiting portion (not shown), and 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) and a second positioning portion (not shown), and 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 cigarette 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 the first positioning portion is opposite to the second limiting portion and the second positioning portion is opposite to the first limiting portion during assembly, the cigarette cartridge 10 cannot be installed in place. In this embodiment, the two opposite surfaces of the battery housing 24 constitute the first limiting surface and the second limiting surface, and the first limiting surface and the second limiting surface both extend from the first end along the axial direction of the battery device 20 to the second end, and the distance of the first limiting surface extending in the axial direction of the battery device 20 is less than the distance of the second limiting surface extending in the axial direction of the battery device 20. The side of the first limiting surface located at the second end is the first limiting portion, and the side of the second limiting surface located at the second end is the second limiting portion. Correspondingly, the two opposite surfaces of the mouthpiece 13 constitute the first positioning surface and the second positioning surface, and the first positioning surface and the second positioning surface both extend from the suction end along the axial direction of the cigarette cartridge 10, and the distance that the first positioning surface extends in the axial direction of the cigarette cartridge 10 is greater than the distance that the second positioning surface extends in the axial direction of the cigarette cartridge 10. The side of the first positioning surface away from the suction end is the first positioning portion, and the side 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 be arranged in other ways, as long as they are not arranged symmetrically along the central axis of the battery device 20. Similarly, the first positioning portion and the second positioning portion can be arranged symmetrically along the central axis of the cigarette cartridge 10.For example, the first limiting portion and the second limiting portion may be located on the same side of the open end of the battery housing 24. Specifically, the side is a hypotenuse, the lower end of the hypotenuse is the first limiting portion, and the higher end of the hypotenuse is the second limiting portion. Correspondingly, the first positioning portion and the second positioning portion are located on the same side of the mouthpiece 13 away from the suction end. The side is a hypotenuse, the end of the hypotenuse farther from the suction end is the first positioning portion, and the end of the hypotenuse closer to the suction end is the second positioning portion.

[0205] Please refer again Fig.11 In a specific embodiment, at least one through groove 212 is provided on the heating element 21, which passes through the upper and lower surfaces of the heating element 21, so that smoke can flow out after passing through the heating element 21. On the other hand, when the smoke bomb 10 is installed in place, the liquid absorbing member 17 can be deformed under the action of 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, thereby increasing the contact area between the heating element 21 and the liquid absorbing member 17, thereby improving the atomization efficiency. The length of the through groove 212 is 1-2mm, and the width is 0.2-0.5mm. 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 of the mounting 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 smoke liquid from leaking through the through groove 212.

[0206] In addition, the heating element 21 is in the form of a thin sheet, and the thickness of the heating element 21 is 0.2-3mm. In a specific embodiment, the thickness of the heating element 21 is 0.45-0.55mm. 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 easy to break. The selection range of the maximum width of the heating element 21 is 1.5-4.5mm. In a specific embodiment, the selection range of the maximum width of the heating element 21 is 2.5-3.5mm. The selection range of the maximum length of the heating element 21 is 2.5-13.5mm. In a specific embodiment, the selection range of the maximum length of the heating element 21 is 4-5mm. The maximum width and maximum length of the heating element 21 are within the above range, which can ensure that the heating element 21 can smoothly pass through the lower end opening of the atomizing chamber 151, and can ensure that the heating element 21 has sufficient heating area. Through holes (not shown) are provided on both sides of the heating element 21, and the through groove 212 is located between the two through holes. The pin 211 is inserted into the through hole and welded to the heating element 21. The pin 211 is made of hard material, so that during the installation of the cigarette cartridge 10, the heating element 21 will not be compressed and deformed or offset.

[0207] Also, see Fig.14The conductive column 231 used to install the heating element 21 is an elastic conductive column. In this way, when installed, the heating element 21 is in elastic contact with the liquid absorbing element 17, so that a certain processing error can be allowed to ensure that the heating element 21 and the liquid absorbing element 17 fit each other. In a specific embodiment, the conductive column 231 includes a first connecting portion and a second connecting portion. The first connecting portion and the heating element 21 are relatively fixed, and the second connecting portion is relatively fixed to the battery device body. The first connecting portion can move away from or toward the second connecting portion under the action of an external force. Specifically, the first connecting portion is a fixed tube 2314 and a claw 2315 installed in one end of the fixed tube 2314, and the second connecting portion is an outer sleeve 2311, and the fixed tube 2314 is movably arranged in the outer sleeve 2311. The conductive column 231 also includes an elastic member 2312 and an insulating member 2313 housed in the outer sleeve 2311. One end of the elastic member 2312 elastically abuts against the lower end of the outer sleeve 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 the fixed tube 2314 is pressed, the elastic member 2312 can be compressed by the insulating member 2313 to retract into the outer sleeve 2311. When the pressing action on the fixed tube 2314 is released, the fixed tube 2314 is in the elastic member 2213. 312 moves upward under the reset action and partially extends out of the outer sleeve 2311. The claw 2315 includes a clamp 2317 fixedly connected to the inner wall of the outer sleeve 2311 and a clamping portion 2318 installed on the lower end surface of the clamp 2317. The clamping portion 2318 is bent relative to one end of the clamp 2317 toward the central axis of the clamp 2317. 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 fixing of the heating element 21. The operation is simple and convenient. 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 by the insulating member 2313 and do not contact each other, and the insulating member 2313 is made of insulating material. The size of the conductive column 231 is relatively small, which makes the elastic member 2312 installed inside the conductive column 231 very small. If a current passes through the elastic member 2312, the elastic member 2312 will be easily burned out. Under the action of the insulating member 2313, when the power is turned on, the current will not flow through the elastic member 2312, but will flow through the outer sleeve 2311, the fixing tube 2314, and the claw 2315, which can prevent the current from passing through the elastic member 2312 when the heating element 21 is working, causing the elastic member 2312 to be heated and damaged. 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 elastic member 2312 from shifting in position during multiple pressing and resetting, which will cause the elastic member 2312 to fail.It can be understood that the elastic member 2312 includes but is not limited to a spring, a stainless steel shrapnel or a copper shrapnel or other elastic and rigid elements.

[0208] See also Fig.12 , Fig.13 and Fig.15 In the present invention, the battery 233 is a rechargeable battery. The battery device 20 is provided with a charging connection portion (not shown) on a side away from the heating element 21. The charging connection portion includes a second control board 235, a connection column 281 and a contact electrode 282. The contact electrode 282 is connected to the second control board 235 through the connection column 281. The battery holder 23 is provided with a through hole for exposing the contact electrode 282. Correspondingly, please refer to Fig.16 , Fig.17 A charging stand 40 for charging a battery 233 is provided with an electronic cigarette connection part 41 and a power connection part 42. The electronic cigarette connection part 41 is provided with an electronic cigarette slot 411 and a charging column 412 located in the electronic cigarette slot 411. The electronic cigarette slot 411 is used to fix the electronic cigarette, and the charging column 412 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 electronic cigarette connection part 41 and the power connection part 42 are at a set angle, 90°<set angle<180°, for example, 155°, so that the electronic cigarette can be prevented from interfering with protruding objects on the wall during charging, and it is also convenient for users to take it.

[0209] Please refer again Fig.12 , Fig.13 and Fig.15 In order to allow the user to clean the residue of the heating element 21 as needed, in the present embodiment, an operating part 27 is further provided on the battery device 20, and the operating 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 under the operation of the user to clean the residue on the heating element 21. A through hole is provided at the lower end of the battery holder 23 for accommodating the operating part 27. When the self-cleaning function is needed, the user can extend a tool into the through hole and press the operating part 27 to trigger it. The operating part 27 is concealed to avoid misoperation.

[0210] Also, see Figure 1 , Fig.12 and Fig.13 In order to facilitate the user to understand the use status of the electronic cigarette, an indicator light 30 is also provided on the battery device 20. The indicator light 30 is fixed to the battery bracket 23 through a lamp post support 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.

[0211] The control method of the electronic cigarette in the above embodiment is described in detail below.

[0212] See also Fig.19 The electronic cigarette control method of this embodiment includes but is not limited to the following steps:

[0213] Step S1, detecting a separation signal generated when the cigarette cartridge is removed from the battery device, wherein an aerosol-forming matrix is ​​stored in the cigarette cartridge, and a heating element is provided on the battery device, and the heating element is used to heat the aerosol-forming matrix in the cigarette cartridge when power is turned on;

[0214] Step S2, when the separation signal is detected, the heating element is controlled to work to remove the residue on the heating element.

[0215] 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 matrix is ​​stored in the cartridge, and the aerosol-forming matrix can be a substance that can produce inhalable smoke, such as smoke liquid, smoke paste, and tobacco. The battery device is provided with a heating element, and the heating element is used to heat the aerosol-forming matrix 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, and at this time, the heating element may be attached with residues left during use. The residue is, for example, an aerosol-forming matrix remaining on the heating element or a carbide produced by heating. In one embodiment, the aerosol-forming matrix is ​​smoke liquid, and a corresponding liquid absorbing element is provided on the cartridge to supply the smoke liquid to the heating element. When the cartridge is installed on the battery device, the liquid absorbing element is in contact with or close to the heating element, so that the smoke liquid stored in the cartridge can be supplied to the heating element for atomization.

[0216] Corresponding to the first embodiment, when the first sensor and the second sensor are provided on the battery device, the step of detecting the separation signal generated when the cigarette cartridge is removed from the battery device includes:

[0217] Obtaining a first airflow signal of a first sensor and a second airflow signal of a second sensor, wherein the first sensor is disposed in a first cavity on the battery device, the second sensor is disposed in a second cavity on the battery device, the first cavity is communicated with an airflow channel of the electronic cigarette and isolated from the second cavity, and 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;

[0218] If the first airflow signal is at a low level and the second airflow signal is at a high level, a separation signal generated when the cigarette cartridge is removed from the battery device is detected.

[0219] 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.

[0220] 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.

[0221] 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:

[0222] 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.

[0223] Among them, if the first airflow signal and the second airflow signal are both low levels, it means that the electronic cigarette is in an idle state and the heating element does not work. When the electronic cigarette is smoked without installing a cigarette cartridge, airflow will pass through the first cavity and the second cavity, and the first airflow signal and the second airflow signal are both high levels. If a child obtains the electronic cigarette and smokes the electronic cigarette at this time, controlling the heating element to work will cause burns. Therefore, when the first airflow signal and the second airflow signal are both high levels, the heating element does not work.

[0224] 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:

[0225] 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 operate according to the corresponding operating parameters when the electronic cigarette is in a puffing state.

[0226] Among them, when the user draws on the electronic cigarette, there is airflow passing through 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 airflow signal of the second sensor is combined to determine whether the cigarette cartridge is currently in the installed state. When the user draws on the electronic cigarette, only when the second cavity is in a closed state, the second sensor will not detect the airflow change. It can be seen that if the second airflow signal is a low-level signal at this time, it indicates that the second cavity is in a closed state and the cigarette 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 cigarette cartridge has been installed and the user is drawing. 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 drawing state, that is, controls the heating element to perform normal atomization work.

[0227] 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:

[0228] 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;

[0229] If the time length during which the resistance of the heating element rises to the preset resistance length is greater than or equal to the preset time length, the output power of the heating element is controlled so that the resistance of the heating element is maintained at the preset resistance length.

[0230] 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.

[0231] In another embodiment, corresponding to the above second embodiment, when a state detection circuit is provided on the battery device, step S1 detects a separation signal generated when the cigarette cartridge is removed from the battery device, including:

[0232] Obtaining an on / off signal of a status detection circuit, wherein the status detection circuit is used to detect the installation status of the cigarette cartridge, the status detection circuit is arranged on the battery device, the status detection circuit is in an on state when the cigarette cartridge is installed on the battery device, and the status detection circuit is in an off state when the cigarette cartridge is separated from the battery device;

[0233] If the on-off signal is a disconnection signal, a separation signal generated when the cigarette cartridge is removed from the battery device is detected.

[0234] 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.

[0235] 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.

[0236] 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:

[0237] 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;

[0238] 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.

[0239] 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.

[0240] 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:

[0241] 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;

[0242] 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.

[0243] 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.

[0244] In one embodiment, the electronic cigarette control method may further include the following steps:

[0245] Controlling the heating element to work according to the received preset operation signal to remove the residue on the heating element;

[0246] During the operation of the heating element, the resistance change rate of the heating element is obtained;

[0247] If the resistance value change rate is less than the preset change rate, the heating element is controlled to stop working;

[0248] If the resistance value change rate is greater than or equal to the preset change rate, the heating element is controlled to work to remove the residue on the heating element.

[0249] Among them, a self-cleaning manual button is also provided at the bottom of the electronic cigarette. When the manual button is pressed, a preset operation signal is generated to control the heating element to work, and the heating element starts to heat and self-clean. The preset change rate refers to the resistance change rate when the heating element works to remove residues without installing the cigarette 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 without installing the cigarette cartridge. During the self-cleaning process, if the cigarette cartridge is still inserted in the electronic cigarette, the heating element will have a resistance change rate less than the preset change rate due to the attachment of more aerosol-forming matrix. At this time, continuing to self-clean will damage the cigarette cartridge. To ensure that the cigarette cartridge is intact, the heating element is controlled to stop working and self-cleaning is stopped. 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-forming matrix in the cigarette cartridge, and the residue can be cleaned. At this time, the heating element is controlled to work.

[0250] In the control method of the electronic cigarette of the present invention, an aerosol-forming 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-forming matrix in the cartridge when power is turned on. When a separation signal indicating that the cartridge is removed from the battery device is detected, the heating element is controlled to work to remove the residue on the heating element. In this way, the present invention can automatically remove the residue on the heating element for self-cleaning when the cartridge is removed from the battery device, thereby increasing the service life of the heating element.

[0251] Fig.28 FIG. 1 is a schematic diagram of the structure of an electronic cigarette in an exemplary embodiment of the present invention. Fig.28 As 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 implements the above-mentioned electronic cigarette control method by loading and executing the at least one program instruction.

[0252] For specific steps executed by the processor 320 in this embodiment, please refer to Figures 1 to 27 The description of the illustrated embodiment will not be repeated here.

[0253] The present invention also provides a computer storage medium, on which computer program instructions are stored; when the computer program instructions are executed by a processor, the electronic cigarette control method as described above is implemented.

[0254] The aforementioned storage media include: U disk, mobile hard disk, read-only memory (ROM), random access memory (RAM), disk, optical disk or cloud and other media that can store program code.

[0255] The specific steps implemented when the computer program instructions stored in the computer storage medium of this embodiment are executed by the processor are shown in FIG. Figures 1 to 27 The description of the illustrated embodiment will not be repeated here.

[0256] Please refer to Fig.29 , which shows a method flow chart of a method for controlling an electronic cigarette provided by an embodiment of the present invention. Fig.29 As shown, the control method of the electronic cigarette may include:

[0257] Step 110, detecting whether the standby condition of the electronic cigarette is met.

[0258] This step can be achieved in two ways:

[0259] The first method is to determine whether the electronic cigarette is operated; if the electronic cigarette is not operated for a predetermined time, it is determined that the standby condition of the electronic cigarette is met. The predetermined time can be set by the developer or customized by the user.

[0260] The specific implementation of determining whether the electronic cigarette is operated may be: obtaining the operated information of the electronic cigarette, the operated information including the cigarette lighting information and the movement indication information; and determining whether the electronic cigarette is operated according to the operated information.

[0261] The lighting information is whether the electronic cigarette is lit, that is, whether the atomization component in the electronic cigarette is performing atomization; 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 chamber of the electronic cigarette, and the flow information of the liquid in the liquid storage chamber of the electronic cigarette;

[0262] Optionally, the specific implementation of determining whether the electronic cigarette is operated according to the cigarette lighting information may be: when the cigarette lighting signal is not detected, determining that the electronic cigarette is not operated for inhalation; or, when the atomization work is not performed according to the cigarette lighting signal, determining that the electronic cigarette is not operated for inhalation; or, if the cigarette lighting signal and the inhalation signal are detected, determining that the electronic cigarette is operated for inhalation, otherwise determining that the electronic cigarette is not operated for inhalation.

[0263] Among them, the cigarette lighting signal involved in the present application can be a signal generated when the cigarette lighting button on the electronic cigarette is operated. The cigarette lighting signal can also be an airflow signal detected by a sensor component in the electronic cigarette. The airway where the sensor component is located is connected to the mouthpiece of the electronic cigarette. When the user inhales through the mouthpiece of the electronic cigarette, since the sensor component is arranged in the airway connected to the mouthpiece, the sensor component can detect changes in the airflow in the airway, such as changes in air pressure, changes in airflow velocity, etc. The sensor component can be a sensor for detecting airflow, such as an air pressure sensor, an airflow sensor, a pressure sensor, etc.

[0264] Optionally, when the cigarette lighting signal is not an airflow signal detected by the sensor component in the electronic cigarette, the inhalation signal may be an airflow signal detected by the sensor component in the electronic cigarette.

[0265] Optionally, determining whether the electronic cigarette is operated according to the movement indication information may be specifically implemented as follows: if it is determined according to the movement indication information that the electronic cigarette is stationary, then determining that the electronic cigarette is not operated.

[0266] When the user holds the electronic cigarette and rotates or moves it, the electronic cigarette generates acceleration, the liquid surface in the liquid storage chamber shakes, and the liquid in the liquid storage chamber flows. 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.

[0267] Among them, determining whether the electronic cigarette is stationary according to the movement indication information can be achieved 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 in the liquid storage chamber is lower than or equal to a predetermined threshold, it is determined that the electronic cigarette is not operated; 3. If the flow rate of the liquid in the liquid storage chamber 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.

[0268] In the present application, the liquid level height can be detected by setting a liquid level detector in the liquid storage chamber, the acceleration detection of the electronic cigarette can be detected by a gyroscope or other acceleration detection components in the electronic cigarette, and the flow speed of the smoke liquid in the liquid storage chamber can be detected by a flow speed detection device in the liquid storage chamber. The present application does not specifically limit the height detection method, acceleration detection method, and smoke liquid flow information detection method.

[0269] The second method is to detect whether a standby command is received; if a standby command is received, it is determined that the standby condition of the electronic cigarette is met. The standby command may be a standby command generated by the operation of the child lock button on the electronic cigarette, or a standby command generated by the electronic cigarette being knocked, or other standby commands, which will not be described in detail in this embodiment.

[0270] Optionally, the specific implementation of detecting whether the standby command is received may be: obtaining the knocking information of the electronic cigarette; determining whether the standby command is received according to the knocking information. Optionally, a 3D sensor may be provided in the electronic cigarette, and the data detected by the 3D sensor may be used to determine whether the electronic cigarette is knocked to obtain the knocking information; when the knocking information of the electronic cigarette indicates that the electronic cigarette is knocked continuously for a second predetermined number of times, it is determined that the knocking command is received, and the second predetermined number of times may be set by the developer or defined by the user.

[0271] Step 120: If the standby condition of the electronic cigarette is met, the electronic cigarette is controlled to enter the standby state.

[0272] Step 130: if a cigarette lighting signal is detected when the electronic cigarette is in the standby state, the electronic cigarette stops controlling the atomization component to perform atomization according to the cigarette lighting signal.

[0273] By controlling the electronic cigarette to enter a standby state, the electronic cigarette in the standby state stops controlling the atomization component to perform atomization work according to a cigarette lighting signal, so as to temporarily turn off the cigarette lighting function of the electronic cigarette.

[0274] For example, after an e-cigarette user uses the e-cigarette to inhale, when the e-cigarette is left stationary for a preset time of 1 minute, the e-cigarette is controlled to enter standby mode, and the e-cigarette stops atomizing according to the cigarette lighting signal; at this time, if a child grabs the e-cigarette and accidentally touches the cigarette lighting button, the e-cigarette will no longer atomize according to the cigarette lighting signal, thus preventing the atomized smoke from being accidentally inhaled by the child.

[0275] In summary, the method provided by the embodiment of the present invention detects whether the standby condition of the electronic cigarette is met; if the standby condition of the electronic cigarette is met, the electronic cigarette is controlled to enter the standby state; if a cigarette lighting signal is detected when the electronic cigarette is in the standby state, the electronic cigarette stops controlling the atomization component to perform atomization according to the cigarette lighting signal; the problem in the related art that a child grabs the electronic cigarette and accidentally touches the cigarette lighting button, and the smoke atomized by the electronic cigarette is inhaled by the child, which damages the child's physical and mental health; the effect of increasing the child protection function of the electronic cigarette is achieved.

[0276] After the electronic cigarette enters the standby state, the electronic cigarette user can generate an atomization wake-up signal by operating the electronic cigarette to start the atomization function of the electronic cigarette. The specific implementation can be: when the electronic cigarette is in the standby state, if the atomization wake-up signal is detected, the electronic cigarette is controlled to enter the working state; when the electronic cigarette is in the working state, if a cigarette lighting signal is detected, the atomization component is controlled to perform atomization according to the cigarette lighting signal.

[0277] In one example, the electronic cigarette user can trigger the electronic cigarette to enter the working state by removing a predetermined component from the electronic cigarette and then installing it. The specific implementation may be: if after detecting that the predetermined component in the electronic cigarette is removed, it is detected that any predetermined component is installed to the body of the electronic cigarette, it is determined that the atomization wake-up signal is detected, and the predetermined component is an atomizer or a cigarette cartridge.

[0278] In one example, a probe or a button switch is provided on the mounting base, and when the predetermined component is mounted on the mounting base, the predetermined component abuts the probe or presses the button switch; when the electronic cigarette detects an operation signal generated by the probe being abutted or the button switch being pressed, it determines that the predetermined component is installed on the body of the electronic cigarette.

[0279] In another example, a heating element is provided in the predetermined component, and when the predetermined component is installed on the mounting base, the heating element is connected to the load access circuit in the electronic cigarette body; when the electronic cigarette detects that a load is connected to the load access circuit, it determines that the predetermined component is installed to the electronic cigarette body.

[0280] In another example, a magnetic part is provided in the predetermined component, and a Hall switch is provided on the mounting base. When the predetermined component is installed on the mounting base, the Hall switch detects the magnetic part; the electronic cigarette detects whether the predetermined component is installed on the mounting base through the Hall switch. In actual implementation, the magnetic part can be a magnetic ring or a circular magnetic sheet provided at the bottom or end of the cigarette cartridge.

[0281] Optionally, a receiving cavity for a predetermined component is provided on the electronic cigarette body, and a mounting base for the predetermined component is provided in the receiving cavity; the electronic cigarette user can install the predetermined component on the electronic cigarette body by inserting the predetermined component into the receiving cavity; the electronic cigarette can also separate the predetermined component from the electronic cigarette body by pulling the predetermined component out of the receiving cavity. In this embodiment, the electronic cigarette user can trigger the electronic cigarette to enter a working state by pulling the predetermined component out of the receiving cavity and then inserting it again.

[0282] In another embodiment, the electronic cigarette user can trigger the electronic cigarette to enter the standby state by pulling out the predetermined component from the receiving cavity; and then insert the predetermined component into the receiving cavity to trigger the electronic cigarette to enter the working state. The specific implementation can be: when it is detected that the predetermined component is separated from the body of the electronic cigarette, it is determined that the standby instruction is received, and the electronic cigarette is controlled to enter the standby state according to the standby instruction; when it is detected that the predetermined component is installed on the body of the electronic cigarette, it is determined that the atomization wake-up signal is detected, and the electronic cigarette is controlled to enter the working state according to the atomization wake-up signal.

[0283] In another example, when the electronic cigarette meets the standby condition, the electronic cigarette is controlled to enter the standby state, and the predetermined component in the electronic cigarette is controlled to be separated from the body of the electronic cigarette, and the predetermined component is an atomizer or a cigarette cartridge. In this method, the electronic cigarette user can then install the predetermined component to the body of the electronic cigarette, for example, insert the predetermined component into the mounting base of the corresponding accommodating cavity; when the electronic cigarette detects that the predetermined component is installed to the body of the electronic cigarette, the electronic cigarette is controlled to enter the working state; and if a cigarette lighting signal is detected, the atomization component is controlled to perform atomization.
