The top of the stopper 111 is also provided with a smoke outlet 1112 communicating with the inner cavity of the stopper 111. The stopper 111 is provided with a first partition plate 1113 and a second partition plate 1114 extending downwardly along the axial direction of the stopper 111, and the first partition plate 1113 is close to the air inlet 1111, and the second partition plate 1114 is close to the smoke outlet 1112. In this embodiment, the first partition plate 1113, the second partition plate 1114 and the top inner surface of the stopper 111 are integrally formed. It can be understood that in other embodiments not shown, the first partition plate 1113 and the second partition plate 1114 are integrally formed with each other. The two partition plates 1114 can also be connected to the top inner surface of the stop portion 111 by means of snap-fitting, plugging, etc. The first partition plate 1113 and the side of the stop portion 111 on which the air inlet hole 1111 is provided form a chamber enclosed, and the chamber forms an air inlet channel 1115 connected to the air inlet hole 1111. The second partition plate 1114 and the side of the stop portion 1111 close to the smoke outlet 1112 form a chamber enclosed between the smoke outlet 1116 connected to the smoke outlet 1112. The first partition plate 1113, the second partition plate 1114 and the top inner wall of the stopper 111 form a liquid storage chamber 1117 for storing liquid smoke. The stopper 111 is also provided with a liquid injection hole 1118 connecting the liquid storage chamber 1117 and the outside. In this embodiment, a liquid smoke plug 1119 is provided in the liquid injection hole 1118. The liquid smoke plug 1119 is made of rubber material. It can be understood that in other embodiments not shown, the liquid smoke plug 1119 is 119 can also be made of other materials with good sealing properties such as silicone. When the user needs to inject liquid, the user can drip liquid into the liquid storage chamber 1117 through the injection hole 1118. After the user has finished injecting liquid into the liquid storage chamber 1117 through the injection hole 1118, the liquid plug 1119 is installed in the injection hole 1118. The liquid plug 1119 can seal the injection hole 1118 to prevent the liquid in the liquid storage chamber 1117 from leaking from the injection hole 1118 to the outside.

[0062] Grooves 1121 are formed on two side walls of the connecting portion 112 , and a protrusion 1122 for connecting with the lower cover structure 12 is formed on the groove wall of each groove 1121 .

[0063] Please see Figure 2 and, Figure 3 as well as Figure 5The lower cover structure 12 includes an atomizing housing 121 connected to the connecting portion 112, a heating element 122 installed in the atomizing housing 121, and a liquid absorbing element 123 disposed on the top of the heating element 122. In this embodiment, the lower cover structure 12 is connected to one end of the cartridge housing 11 through a connecting structure (not shown in the figure), and the liquid absorbing element 123 can be taken out from the cartridge housing 11 by operating the lower cover structure 12.

[0064] The atomizing housing 121 includes a body 1211 disposed in the connecting portion 112 and a sealing cover 1212 disposed at the lower end of the body 1211 .

[0065] A placement groove 1213 for accommodating the liquid absorbent component 123 is provided at the top of the main body 1211, and bending grooves 1214 for installing the heating component 122 are provided at both ends of the bottom groove wall of the placement groove 1213, which are bent inward along the axial direction of the main body 1211. The side walls at both ends of the main body 1211 are recessed with hollow grooves 1215 along the radial direction of the main body 1211. Each hollow groove 1215 has at least one guide hole (not shown) on the groove wall. In this embodiment, the guide hole on the groove wall of one of the hollow grooves 1215 connects the air inlet channel 1115 and the placement groove 1213, and the guide hole on the groove wall of the other hollow groove 1215 connects the air outlet channel 1116 and the placement groove 1213.

[0066] Two insertion holes 1216 are provided at the lower ends of the sealing cover 1212 corresponding to the two bending grooves 1214, and each insertion hole 1216 is connected to its corresponding bending groove 1214. The two ends of the sealing cover 1212 protrude upward along the axial direction of the sealing cover 1212 to form two clips 1217 for connecting to the connecting part 112. The two clips 1217 radially correspond to the two empty grooves 1215 respectively, and each clip 1217 is provided with a clip groove 1218 corresponding to the protrusion 1122. In this embodiment, the clamping member 1217 is a connecting structure. Since there is a certain radial gap between each clamping member 1217 and the groove wall of the radially corresponding empty groove 1215, and the outer surface of the side wall of the connecting portion 112 and the outer surface of the protrusion 1122 arranged on the outer surface of the side wall are not in the same plane, there is a certain difference, by leaving a radial gap, the two side walls of the connecting portion 112 provided with the protrusion 1122 can be placed in the two gaps respectively, and the lower cover structure 12 can be connected to the cartridge housing 112 through the clamping grooves 1218 and the two protrusions 1122 respectively. The protrusion 1122 is connected so that the lower cover structure 12 can be kept fixed relative to the cigarette cartridge shell 11, and by providing a hollow groove 1215 on both sides of the main body 1211, when the two side walls of the connecting part 112 with the protrusion 1122 are respectively placed in two gaps, it is convenient for the user to adjust the position of the protrusion 1122 and the snap-in groove 1218 during assembly to prevent assembly misalignment. It can be understood that the hollow groove 1215 can be omitted. When the hollow groove 1215 is omitted, the two snap-in parts 1217 are made of soft materials such as silicone and rubber, which is convenient for the user to install the protrusion 1122 in the snap-in groove 1218. It is understandable that in other embodiments not shown, the positions of the clamping member 1217 and the protrusion 1122 can be interchanged, that is, the clamping member 1217 can also be set on the cartridge housing 11, and the protrusion 1122 can also be set on the atomizer housing 121, as long as the protrusion 1122 is installed in the clamping groove 1218 so that the lower cover structure 12 can be fixed relative to the cartridge housing 11. It is understandable that in other embodiments not shown, the lower cover structure 12 can also be connected to the cartridge housing 11 by magnetic connection, threaded connection, etc.

[0067] It can be understood that the type of the heating element 122 can be a heating wire, a heating net, a heating plate, etc. The heating element 122 can be made of steel, nickel alloy, ceramic and other materials. In the present embodiment, the heating element 122 is a steel heating plate sintered with a conductive paste. The heating element 122 is arranged in the placement groove 1213. The two ends of the heating element 122 are respectively passed through the two bending grooves 1214 and then bent inward along the radial direction of the main body 1211 to form a bending end 1221. A connection hole for connecting to the battery device 20 is provided on each bending end 1221 corresponding to the socket 1216 (not shown in the figure).

[0068] The liquid absorbing member 123 is arranged in the placement groove 1213 and abuts against the heating member 122. In this embodiment, the liquid absorbing member 123 is arranged on the top of the heating member 122. It can be understood that in other embodiments not shown, the liquid absorbing member 123 can also be arranged at the bottom of the heating member 122, as long as the liquid absorbing member 123 at least partially abuts against the heating member 122. The liquid absorbing member 123 is made of cotton, cotton cloth or porous ceramics, which are easy to absorb liquid. The liquid absorbing member 123 can gradually absorb the smoke liquid and gradually conduct the absorbed smoke liquid to the heating member 122, so that the heating member 122 heats the smoke liquid absorbed by the atomized liquid absorbing member 123. The space for the heating member 122 to heat the atomized smoke liquid forms an atomizing chamber 1222 that is connected to both the air inlet channel 1115 and the air outlet channel 1116.

[0069] Please see Figure 2 In the present embodiment, the liquid inlet cover 13 and the cigarette cartridge shell 11 are two detachable parts, and the liquid inlet cover 13 is installed in the cigarette cartridge shell 11, and one end of the liquid inlet cover 13 is located between the main body 1211 and the first partition plate 1113 and abuts against the top surface of one end of the main body 1211, and the other end of the liquid inlet cover 13 is located between the main body 1211 and the second partition plate 1114 and abuts against the top surface of the other end of the main body 1211, so that the liquid inlet cover 13 can remain fixed relative to the cigarette cartridge shell 11. It can be understood that in other embodiments not shown, one end of the liquid inlet cover 13 can be connected to the side wall of the first partition plate 1113, and the other end of the liquid inlet cover 13 can be connected to the side wall of the second partition plate 1114. The connection methods include but are not limited to snap-in, plug-in, threaded connection, etc. It can be understood that in other embodiments not shown, the two ends of the liquid inlet cover 13 are respectively integrally formed with the first partition plate 1113 and the second partition plate 1114, as long as the liquid inlet cover 13 can remain fixed relative to the cigarette cartridge shell 11. The liquid inlet cover 13 is provided with at least one liquid inlet hole 131 communicating with the liquid storage cavity 1117 and the placement groove 1213 , so that the smoke liquid in the liquid storage cavity 1117 can flow through the liquid absorption component 123 through the liquid inlet hole 131 and be gradually absorbed by the liquid absorption component 123 .

[0070] Please see Figure 2 and Figure 6 The battery device 20 includes a battery housing 21 which is covered outside the lower cover structure 12 and abutted against the lower end of the stopper 111, a control board 23 and a battery 24 accommodated in the battery housing 21, a button structure 25 installed on the battery housing 21, and two electrode contacts 26 installed above the battery housing 21 at intervals.

[0071] The battery housing 21 is provided with a receiving cavity 211 for installing the cigarette cartridge 10. In the present embodiment, by placing the connecting portion 112 in the receiving cavity 211, the top end of the battery housing 21 and the lower end of the stop portion 111 are abutted against each other, so that the battery device 20 can remain fixed relative to the cigarette cartridge 10. It can be understood that in other embodiments not shown, the battery housing 21 can also be connected to the stop portion 111 by magnetic connection, snap connection, etc., so that the battery device 20 can remain fixed relative to the cigarette cartridge 10.

[0072] The control board 23 and the battery 24 are sequentially arranged from top to bottom along the axial direction of the battery housing 21 .

[0073] The button structure 25 includes at least one button 251 mounted on the battery housing 21 and an electronic switch 252 provided in the battery housing 21 and connected to the control board 25 and one of the buttons 251. In this embodiment, the user presses the button 251 connected to the electronic switch 252 so that the button 251 can start or turn off the electronic switch 252, thereby controlling the opening or closing of the battery device 20. It can be understood that in other embodiments not shown, the electronic switch 252 can be omitted. When the electronic switch 252 is omitted, each button 251 is connected to the control board 23, and one of the buttons 251 can be used to control the opening or closing of the battery device 20, one of the buttons 251 can be used to control the increase of the power output of the battery device 20 to the cigarette cartridge 10, and one of the buttons 251 can be used to control the reduction of the power output of the battery device 20 to the cigarette cartridge 10. It can be understood that the function and number of the buttons 251 are not limited, and can be set according to the control requirements of the battery device 20.

[0074] In this embodiment, the two electrode contacts 26 are fixed on the bottom groove wall of the accommodating cavity 211, and the fixing methods include but are not limited to snap-on, threaded connection, etc. The distance between the two electrode contacts 26 is equal to the distance between the two jacks 1216. One end of each electrode contact 26 is passed through the groove wall of the accommodating cavity 211 and connected to the control board 23. When the battery device 20 and the cigarette cartridge 10 are connected, the end of each electrode contact 26 away from the control board 23 can pass through the jack 1216 and the connecting hole in turn and remain fixed to the heating element 122.

[0075] Installation process: First, install the lower cover structure 12 on the lower end of the cartridge housing 11. The lower cover structure 12 is connected to the protrusion 1122 of the cartridge housing 11 through the snap-in groove 1218. The lower cover structure 12 can remain fixed relative to the cartridge housing 11, so that the sealing cover 1212 can cover the lower end opening of the cartridge housing 11; secondly, place the connecting part 112 in the accommodating cavity 211, and the top of the battery housing 21 and the lower end of the stopper 111 are abutted, so that the battery device 20 can remain fixed relative to the cartridge 10. At this time, the end of each electrode contact 26 away from the control board 23 can pass through the jack 1216 and the connecting hole in turn and remain fixed to the heating element 122.

[0076] Usage process: When injecting liquid, the user can drip the liquid into the liquid storage chamber 1117 through the liquid injection hole 1118. After the user has finished injecting the liquid into the liquid storage chamber 1117 through the liquid injection hole 1118, the liquid plug 1119 is installed in the liquid injection hole 1118. The liquid plug 1119 can seal the liquid injection hole 1118 to prevent the liquid in the liquid storage chamber 1117 from leaking from the liquid injection hole 1118 to the outside.

[0077] After the cigarette cartridge 10 and the battery device 20 are assembled, the end of each electrode contact 26 away from the control board 23 can pass through the jack 1216 and the connection hole in sequence and connect to the heating element 122, thereby limiting the radial displacement of the electrode contact 26, so that the electrode contact 26 can be more firmly connected to the heating element 122. When the electronic cigarette is started, the circuit is turned on, and the liquid absorbing element 123 gradually conducts the absorbed smoke liquid to the heating element 122, so that the heating element 122 heats the smoke liquid absorbed by the atomized liquid absorbing element 123. When the user inhales, the outside air can pass through the air inlet channel 1115 and mix with the smoke in the atomizing chamber 1222. The mixed smoke then flows out from the smoke outlet 1112 through the air outlet channel 1116 to the outside to be inhaled by the user.

[0078] When the user needs to clean the heating element 122 in the atomizer housing 121 or replace the liquid absorbing element 123 in the atomizer housing 121, the user separates the cigarette cartridge 10 and the battery device 20, and then removes the lower cover structure 12 installed at one end of the cigarette cartridge housing 11, separates the lower cover structure 12 relative to the cigarette cartridge housing 11, and takes out the heating element 122 and the liquid absorbing element 123 installed in the placement groove 1213 at the top of the body 1211. Taking out the heating element 122 and the liquid absorbing element 123 is not only convenient for cleaning the dirt on the heating element 122, but also convenient for replacing the liquid absorbing element 123. When 17 is made of soft materials such as silicone and rubber, by moving one of the clamping parts 1217, the clamping groove 1218 on the clamping part 1217 is disengaged from the protrusion 1122 corresponding to its position, and the other clamping part 1217 is still connected to the cartridge shell 11. At this time, the lower cover structure 12 is rotated around the end relatively fixed to the cartridge shell 11, that is, the end of the clamping part 1217 that is still connected to the cartridge shell 11 is rotated until the heating element 122 and the liquid absorbing element 123 installed in the placement groove 1213 at the top of the main body 1211 can be taken out. The electronic cigarette 100 of this embodiment has a placement groove 1213 on the top of the body 1211. When cleaning the heating element 122 and replacing the liquid absorbent element 123, the heating element 122 and the liquid absorbent element 123 can be taken out by taking them out from above and supporting them from below, thereby preventing the heating element 122 and the liquid absorbent element 123 from falling to the ground, and preventing the smoke liquid absorbed by the liquid absorbent element 123 from overflowing to the outside and causing leakage.

[0086] Please see Fig.10 A placement groove 3311 for placing the heating element 332 is provided on the main body 331 corresponding to the crimping piece 313, and mounting holes 3312 for connecting with the base 333 are respectively provided on both sides of the placement groove 3311 on the main body 331. The upper end of the main body 331 protrudes upward along the axial direction of the main body 331 to form a protrusion 3313 corresponding to the groove 322. In this embodiment, the main body 331 is matched with the protrusion 3313 and the groove 322 so that the main body 331 and the liquid inlet cover 32 remain relatively fixed. It can be understood that in other embodiments not shown, the main body 331 can also be connected to the liquid inlet cover 32 by means of threaded connection or other connection methods.

[0087] It can be understood that the type of the heating element 332 can be a heating wire, a heating net, a heating plate, etc. The heating element 332 can be made of steel, nickel alloy, ceramic and other materials. In the present embodiment, the heating element 332 is a steel heating plate sintered with a conductive paste. The heating element 332 is arranged in the placement groove 3311, and the two ends of the heating element 332 are respectively provided with through holes corresponding to the two mounting holes 3312 (not shown in the figure).

[0088] The base 333 is provided with a connection groove 3331 for mounting the liquid absorbing member 334 corresponding to the heating member 332, and the base 333 is provided with two connection ports 3333 corresponding to the two through holes.

In this embodiment, the end surface of the electrode contact member 335 extending into the mounting hole 3312 is sleeved with a bushing 336, and the outer surface of the bushing 336 abuts against the hole wall of the mounting hole 3312. The electrode contact member 335 can be fixed relative to the heating member 332 through the bushing 336 abutting against the hole wall of the mounting hole 3312. It is understandable that in other embodiments not shown, the end surface of the electrode contact 335 extending into the mounting hole 3312 can also be connected to the wall of the mounting hole 3312 by snapping, so that the electrode contact 335 can remain fixed relative to the heating element 332. In this embodiment, a liquid injection hole 3332 is further provided on the base 333, which passes through the main body 331 and the liquid inlet cover 32 in sequence and is connected to the outside world. A sealing plug (not shown in the figure) is provided in the liquid injection hole 3332, and the sealing plug is made of rubber material. It can be understood that in other embodiments not shown, the sealing plug can also be made of other materials with good sealing properties such as silicone. When the user needs to inject liquid, the user can drip smoke liquid into the liquid storage chamber 311 through the liquid injection hole 3332. When the user has finished injecting smoke liquid into the liquid storage chamber 311 through the liquid injection hole 3332, the sealing plug is installed in the liquid injection hole 3332. The sealing plug can seal the liquid injection hole 3332 to prevent the smoke liquid in the liquid storage chamber 311 from leaking from the liquid injection hole 3332 to the outside world.

[0089] The liquid absorbing member 334 is arranged in the connecting groove 3331. In this embodiment, the upper end surface of the liquid absorbing member 334 and the lower end surface of the heating member 332 are against each other. The liquid absorbing member 334 is made of a material that is easy to absorb liquid, such as cotton, cotton cloth or porous ceramics. The liquid absorbing member 334 can gradually absorb the smoke liquid in the liquid storage chamber 311 that flows to the liquid absorbing member 334 through the lower liquid hole, and gradually conduct the absorbed smoke liquid to the heating member 332, so that the heating member 332 heats the smoke liquid absorbed by the atomized liquid absorbing member 334. The space where the heating member 332 heats the atomized smoke liquid forms an atomizing chamber (not shown in the figure), and the heating member 332 constitutes a part of the peripheral wall of the atomizing chamber. The atomizing chamber is connected to the smoke outlet 312 to form an air outlet channel 3121.

[0090] Please also see Figure 8 and Fig. 9The detachable part 331 of the sealing cover 34 is provided with a clamping portion 341, and the clamping portion 341 is provided with a clamping groove 3411 which can correspond to the buckle 314. The buckle 314 can open or close the connecting groove 3331 and replace the liquid absorbent part 334 in the connecting groove 3331 by cooperating with the clamping groove 3411. It can be understood that in other embodiments not shown, the sealing cover 34 can be detachably connected to the lower end of the cigarette cartridge housing 31. The detachable connection method includes but is not limited to clamping, plugging, magnetic connection and other connection methods. As long as the user can adjust the sealing cover 34 by pushing, rotating or other methods, so that the connecting groove 3331 is exposed, it is convenient for the user to take out the liquid absorbent part 334 located in the connecting groove 3331. For example, when the sealing cover 34 and the lower end of the cartridge housing 31 are connected in a snap-fit ​​manner, there are two snap buckles 314, which are relatively arranged at the lower side of the cartridge housing 31, and there are two snap-fitting portions 341, which are respectively arranged at both ends of the sealing cover 34, and each snap-fitting portion 341 is provided with a snap-fitting groove 3411 corresponding to the snap-fitting groove 314, so that the user can separate at least one snap-fitting portion 314 from the corresponding snap-fitting groove 3411 to make the connection groove 333 1 is exposed, thereby replacing the liquid absorbing member 334 in the connecting groove 3331; for example, when the sealing cover 34 and the lower end of the cartridge housing 31 are connected by magnetic connection, the sealing cover 34 and the cartridge housing 31 are both made of magnetic materials, and the magnetic polarities of the sealing cover 34 and the cartridge housing 31 are different. The user can remove the sealing cover 34 from the cartridge housing 31 to expose the connecting groove 3331, thereby replacing the liquid absorbing member 334 in the connecting groove 3331; for example, when the sealing cover 3 4 and the lower end of the cartridge housing 31 are connected in a rotating manner, an axial hole (not shown in the figure) is opened at the lower end of the cartridge housing 31, and a rotating hole (not shown in the figure) corresponding to the axial hole is opened on the sealing cover 34, and a rotating shaft is arranged in the rotating hole, and one end of the rotating shaft is passed through the rotating hole and extends into the axial hole. It can be understood that there is no limitation on the opening position of the axial hole. The axial hole can be opened at the end of the sealing cover 34, or the axial hole can also be opened at the side of the sealing cover 34. The user can rotate around the end of the sealing cover 34 that is relatively fixed to the cartridge housing 31, so that the connecting groove 3331 is exposed, thereby replacing the liquid absorbing member 334 in the connecting groove 3331. It can be understood that there is no limitation on the direction in which the sealing cover 34 rotates relative to the cartridge housing 31. The sealing cover 34 can rotate along the axial direction of the cartridge housing 31, or the sealing cover 34 can also rotate along the radial direction of the cartridge housing 31. The rotation direction of the sealing cover 34 can be determined according to the position of the axial hole opened on the sealing cover 34.

[0091] In this embodiment, two electrode holes 342 are respectively provided at the lower ends of the two electrode contacts 335 on the sealing cover 34. When the user does not need to replace the liquid absorbent component 334, the sealing cover 34 can cover the lower end of the cartridge housing 31, so that the lower ends of the two electrode contacts 335 are exposed to the outside through the two electrode holes 342 respectively, and the user can connect the battery device through the two partially exposed electrode contacts 335.

[0092] See also Fig. 9 In one embodiment, the sealing cover 34 is also provided with at least one air inlet (not shown) connecting the outside air and the atomizing chamber. When the electronic cigarette is in use, the outside air can enter the atomizing chamber through the air inlet and mix with the smoke. The smoke mixed with the outside air then flows out from the smoke outlet 312 through the air outlet channel 3121 and is inhaled by the user. Fig.11 and Fig.12 In another embodiment, the air inlet connected to the atomization chamber can also be opened on the upper side of the cartridge housing 31, and the inner cavity connected to the air inlet and the atomization chamber forms an air inlet channel 3122. At this time, the outside air can enter the air inlet channel 3122 and flow downward into the atomization chamber to mix with the smoke, and then flow upward through the air outlet channel 3121 to the smoke outlet 312 and out.

[0093] It can be understood that in other embodiments not shown, the base 333 can be omitted. When the base 333 is omitted, the placement groove 3311 is a through groove, and a limiting groove (not shown) for fixing the heating element 332 is opened on the groove wall of the placement groove 3311, and a limiting protrusion (not shown) corresponding to the limiting groove is provided on the heating element 332. The heating element 332 can be stably installed in the placement groove 3311 through the cooperation between the limiting protrusion and the limiting groove; at this time, the suction The liquid part 334 is installed on the side of the placement groove 3311 away from the crimping part 313. The liquid absorbent part 334 can be abutted against the end surface of the heating part 332 away from the crimping part 313. One end of each electrode contact part 335 passes through the through hole in turn and extends into the mounting hole 3312, so that the electrode contact part 335 can remain fixed relative to the heating part 332. The user can adjust the sealing cover 34 to expose the connecting groove 3331, so that the user can take out the liquid absorbent part 334 located in the connecting groove 3331.

[0094] It can be understood that in other embodiments not shown, the sealing plug can be omitted. When the sealing plug is omitted, the sealing cover 34 is provided with a smoke liquid plug 343 corresponding to the injection hole 3332. The smoke liquid plug 343 can be made of silicone, rubber or other materials. When the sealing cover 34 covers the lower end of the cigarette cartridge shell 31, the smoke liquid plug 343 can block the injection hole 3332. When the user needs to inject liquid, the sealing cover 34 can be adjusted to expose the injection hole 3332, and smoke liquid can be added to the liquid storage chamber 311 through the injection hole 3332.

[0095] The battery device is installed on the cigarette cartridge 30 so that the positive and negative electrodes on the battery device can be connected to the two electrode contacts 335 respectively, and the circuit is turned on.

[0096] Installation process: install the liquid inlet cover 32 in the cartridge housing 31, set the heating element 332 in the main body 331, install the main body 331 at the lower end of the liquid inlet cover 32, install the liquid absorbent 334 in the base 333, install the base 333 at the lower end of the main body 331, and install the sealing cover 34 at the lower end of the cartridge housing 31.

[0097] Usage process: By providing a crimping piece 313, the crimping piece 313 can compact the heating element 332 and the liquid absorbing element 334. When the user needs to replace the liquid absorbing element 334, the user can adjust the sealing cover 34 to expose the connecting groove 3331, so that the user can take out the liquid absorbing element 334 located in the connecting groove 3331; when the user needs to clean the dirt on the heating element 332, the user can adjust the sealing cover 34, disassemble the base 333 and the main body 331 in turn, and take out the heating element 332 installed in the main body 331.

[0098] In the electronic cigarette of the present invention, since one end of the lower cover structure 33 is relatively fixed to the cartridge housing 31, the other end of the lower cover structure 33 can be operated and rotated around the end of the lower cover structure 33 relatively fixed to the cartridge housing 31 to expose the liquid absorbent member 334; the electronic cigarette of the present invention is convenient for replacing the liquid absorbent member 334.

[0099] Embodiment 3

[0100] Please also see Figure 13-14The main difference between the cigarette cartridge 30 provided in the third embodiment and the cigarette cartridge 30 in the second embodiment is that an operating groove 346 is provided on the sealing cover 34 corresponding to the liquid absorbing member 334, and a buckle groove 344 is formed along the groove wall of the operating groove 346 extending toward the electrode hole 342, and a blocking member 345 is provided in the operating groove 346. In this embodiment, the blocking member 345 is made of a high temperature resistant transparent material, and the blocking member 345 includes a blocking portion 3451 adapted to the groove diameter of the operating groove 346, and a sealing portion 3451 provided at the side of the blocking portion 3451 and corresponding to the buckle groove 344. The buckling protrusion 3452 and the cover body portion 3453 provided on the sealing portion 3451 at one end away from the operating groove 346, in this embodiment, the blocking member 345 cooperates with the buckling protrusion 3452 and the buckling groove 344, so that the blocking member 345 can be fixed to the sealing cover 34, and when the user needs to replace the absorbent member 334, the user can take out the blocking member 345, and the blocking member 345 is separated from the operating groove 346, so that the connecting groove 3331 is exposed, which is convenient for the user to take out the absorbent member 334 located in the connecting groove 3331. It can be understood that in other embodiments not shown, the blocking member 345 can also be detachably connected to the groove wall of the operating groove 346 by means of plugging, threading, etc. For example, the buckle groove 344 can be omitted. When the buckle groove 344 is omitted, the buckle protrusion 3452 is also omitted. In this case, the blocking member 345 can be made of soft materials such as rubber and silicone, thereby increasing the friction between the outer wall of the blocking portion 3451 and the groove wall of the operating groove 346. The blocking member 345 can be detachably connected to the groove wall of the operating groove 346 through the resistance force between the outer wall of the blocking portion 3451 and the groove wall of the operating groove 346. The sealing cover 34 remains fixed. For example, an external thread section (not shown) is provided on the outer wall of the sealing portion 3451, and an internal thread section (not shown) cooperating with the external thread section is provided on the wall of the operating groove 346. The threaded cooperation between the outer wall of the sealing portion 3451 and the wall of the operating groove 346 enables the sealing member 345 to remain fixed to the sealing cover 34. At this time, as long as the user can operate the sealing member 345, the sealing member 345 will be detached from the operating groove 346, exposing the connecting groove 3331, so that the user can take out the liquid absorbing member 334 located in the connecting groove 3331.In this embodiment, the diameter of the cover body 3453 is larger than the diameter of the blocking portion 3451, so that the operating groove 346 can be better covered to prevent the smoke liquid from leaking from the operating groove 346 when the liquid absorbent member 334 fails to absorb the smoke liquid in time. In addition, since the blocking member 345 is made of a high temperature resistant transparent material, when the outer wall of the blocking portion 3451 and the groove wall of the operating groove 346 cooperate, one end of the blocking portion 3451 can abut against the liquid absorbent member 334, on the one hand, applying a holding force to the liquid absorbent member 334, so that the liquid absorbent member 334 can absorb the smoke liquid in time. The liquid absorbent member 334 can better abut against the heating member 332. On the one hand, it can be judged whether one end surface of the liquid absorbent member 334 and one end surface of the heating member 332 are in place, thereby improving the user experience. On the other hand, it is convenient for the user to observe through the blocking member 345 whether the liquid absorbent member 334 has been fully placed. If the liquid absorbent member 334 is not fully placed, the user can operate the blocking member 345 to place a sufficient amount of liquid absorbent member 334, thereby ensuring that the liquid absorbent member 334 can absorb the smoke liquid in time.

[0101] Embodiment 4

[0102] Please also see Fig.15 The main difference between the cigarette cartridge 30 provided in the fourth embodiment and the cigarette cartridge 30 in the second embodiment is that a shielding groove 347 is provided on the end surface of the sealing cover 34 facing the liquid absorbent member 334, and the shielding groove 347 is a blind groove. In the present embodiment, the groove wall of the shielding groove 347 is roughly rectangular, and a sealing ring (not shown) made of a material with good sealing properties such as silicone and rubber is provided in the shielding groove 347. When the user does not need to take out the liquid absorbent member 334 provided in the connecting groove 3331, the sealing cover 34 is covered, and the sealing ring can abut against the groove wall of the connecting groove 3331 to prevent the smoke liquid absorbed by the liquid absorbent member 334 from overflowing from the connecting groove 3331.

[0103] Embodiment 5

[0104] Please also see Figure 16-19The main difference between the cigarette cartridge 30 provided in the fifth embodiment and the cigarette cartridge 30 in the second embodiment is that the liquid absorbing member 334 and the blocking member 345 are both arranged in the connecting groove 3331, the liquid absorbing member 334 is arranged between the blocking member 345 and the heating member 332, and the blocking member 345 is connected to the groove wall of the connecting groove 3331 to block the connecting groove 3331, and the connection method includes but is not limited to the connection method of snap connection and plug-in connection. In this embodiment, the blocking member 345 is made of a material with good sealing performance such as rubber and silicone, thereby increasing the friction between the outer wall of the blocking member 345 and the groove wall of the connecting groove 3331. Through the resistance force between the outer wall of the blocking member 345 and the groove wall of the connecting groove 3331, the blocking member 345 can prevent the smoke liquid absorbed by the liquid absorbing member 334 from leaking to the outside through the gap between the groove wall of the connecting groove 3331 and the side of the blocking member 345. One end of the blocking member 345 and The groove wall of the connecting groove 3331 is formed in one piece, and the user can adjust the blocking piece 345 by pushing, rotating or other means to expose the connecting groove 3331, so as to take out the liquid absorbing piece 334 located in the connecting groove 3331. The end surface of the sealing cover 34 facing the blocking piece 345 is provided with a pushing protrusion 348 that can cooperate with the blocking piece 345. When the sealing cover 34 is in the process of covering the connecting groove 3331, the pushing protrusion 348 can push the blocking piece 345, so that the blocking piece 345 moves toward the direction of the liquid absorbing piece 334 until it abuts against the liquid absorbing piece 334. The liquid absorbing piece 334 abuts against the heating piece 332 under the push of the blocking piece 345. When the sealing cover 34 completely covers the connecting groove 3331, the blocking piece 345 applies a holding force to the liquid absorbing piece 334 under the abutment of the pushing protrusion 348, so that the liquid absorbing piece 334 can better abut against the heating piece 332.

[0105] Usage process: When the user needs to inject liquid, the user can drip liquid into the liquid storage chamber 311 through the injection hole 3332; when the user needs to replace the liquid absorption piece 334, the user operates the sealing cover 34 relative to the cigarette cartridge shell 31, and the user can take out the blocking piece 345 to expose the connecting groove 3331, thereby taking out the liquid absorption piece 334 located in the connecting groove 3331.

[0106] The above embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
