An inlet is provided on the atomizing head. When the movable member disengages from the switch device, the inlet is in fluid cutoff with the liquid storage cavity. When the movable member presses the switch device, the inlet is in communication with the liquid storage cavity.

[0038] Further, the cartridge further includes an air pipe and a liquid sealing member received in the liquid storage chamber. The liquid sealing member is movable relative to the air pipe. The atomizing head is snap-connected to the liquid sealing member.

[0069] Detailed implementation mode

[0070] Now, the present invention will be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only schematically shows the basic structure of the present invention, so it only shows the components related to the present invention.

[0071] Embodiment 1

[0072] Please refer to Figure 1 、 Figure 2 , Embodiment 1 of the present invention provides an electronic cigarette, which includes a cartridge 10 and an atomization component (not shown in the figure) connected to the cartridge 10. The atomization component is axially movably connected to the cartridge 10. The atomization component includes an atomizer head 20 and a battery component 30. The atomizer head 20 is connected to one end of the battery component 30, and the atomizer head 20 is electrically connected to the battery component 30. When in use, the cartridge 10 supplies e-liquid to the atomizer head 20, and the atomizer head 20 works under the electric drive of the battery component 30. The e-liquid generates smoke under the heating of the atomizer head 20, and the smoke is inhaled by the user. Among them, the cartridge 10 and the atomizer head 20 form an atomizer (not shown in the figure).

[0073] Please refer to Figure 4, the cartridge 10 includes a housing 11, a seal 12 installed at one end of the housing 11, and a liquid-sealing member (not shown in the figure) movably received in the housing 11. Moving the liquid-sealing member can cause the liquid-sealing member 13 to be sealingly connected to or disengaged from the seal 12. When the liquid-sealing member is sealingly connected to the seal 12, the e-liquid is blocked and cannot flow out. When the liquid-sealing member is disengaged from the seal 12, the e-liquid can flow out.

[0074] Specifically, the housing 11 is generally in a hollow cylindrical structure with an opening at the lower end. The inner cavity of the housing 11 forms a liquid storage cavity 110 for storing e-liquid. The top wall of the housing 11 extends downward along the axial direction of the housing 11 to form a ventilation pipe 111. The ventilation pipe 111 is a hollow pipe with upper and lower ends communicating. A suction port 112 is provided at the top of the housing 11. The suction port 112 is in communication with the inner cavity of the ventilation pipe 111 and the outside atmosphere, and the suction port 112 is used for the user's suction operation. In this embodiment, the ventilation pipe 111 and the housing 11 are of an integrally formed structure. It can be understood that in other embodiments not shown, the ventilation pipe 111 and the housing 11 can also be independent components, and they only need to be connected during use.

[0075] The seal 12 is received in the lower end of the housing 11. The outer peripheral surface of the seal 12 is sealingly fitted with the inner peripheral surface of the housing 11. To improve the sealing performance between the seal 12 and the housing 11, the seal 12 is made of a sealing material, including silicone or rubber.

[0076] Further, a jack 121 is axially formed at the center of the seal 12, and the jack 121 penetrates the upper and lower end faces of the seal 12. Further, a slot 122 communicating with the jack 121 is formed by axially downwardly recessing the upper end face of the seal 12. The diameter of the slot 122 is larger than the diameter of the jack 121.

[0077] The liquid sealing member is generally in a cylindrical structure with both ends penetrating. The liquid sealing member includes a liquid sealing part 13 and a sliding sleeve part 131 connected to each other. The liquid sealing part 13 is generally in a hollow sleeve-like structure with an opening at the lower end, and the liquid sealing part can be hermetically connected to the slot 122. The sliding sleeve part 131 protrudes from the upper end surface of the liquid sealing part 13. The sliding sleeve part 131 is generally in a tubular structure with the upper end penetrating. An air vent 132 is provided at the center of the upper end surface of the liquid sealing part 13, and the air vent 132 communicates with both the liquid sealing part 13 and the sliding sleeve part 131. The sliding sleeve part 131 is slidably sleeved outside the air pipe 111. When the sliding sleeve part 131 slides, the liquid sealing part 13 can move under the drive of the sliding sleeve part 131. Specifically, when the sliding sleeve part 131 slides downward relative to the air pipe 111, the liquid sealing part 13 can move downward under the drive of the sliding sleeve part 131 and gradually insert into the slot 122. When the sliding sleeve part 131 slides to the lower end surface of the liquid sealing part 13 abuts against the bottom wall of the slot 122, the liquid sealing part 13 cannot move downward continuously, and the liquid sealing part 13 is hermetically connected to the slot 122. At this time, the liquid sealing member is in the liquid sealing position. In this position, the liquid sealing member closes the liquid storage cavity 110, and the smoke liquid in the liquid storage cavity 110 cannot flow out, and the smoke liquid is separated from the atomizing head 20. When the sliding sleeve part 131 slides upward relative to the air pipe 111, the liquid sealing part 13 can move upward under the drive of the sliding sleeve part 131 and gradually pull out of the slot 122. When the sliding sleeve part 131 slides upward to the lower end surface of the air pipe 111 abuts against the upper end surface of the liquid sealing part 13, the liquid sealing member cannot move upward continuously. At this time, the liquid sealing member 13 is in the liquid discharging position. In this position, the liquid sealing part 13 is completely pulled out of the slot 122, the liquid sealing member opens the liquid storage cavity 110, and the smoke liquid in the liquid storage cavity 110 can flow out, and the smoke liquid is communicated with the atomizing head 20. In order to improve the sealing performance of the liquid storage cavity 110, the liquid sealing member is made of a sealing material, including but not limited to silica gel or rubber.

[0078] It can be understood that in other embodiments not shown, the slot 122 on the sealing member 12 can also be omitted. At this time, when the liquid sealing member is in the liquid sealing state, the lower end surface of the liquid sealing part 13 abuts against the upper end surface of the sealing member 12 to close the liquid storage cavity 110. When the liquid sealing member is in the liquid discharging state, the lower end surface of the liquid sealing part 13 is separated from the upper end surface of the sealing member 12 to open the liquid storage cavity 110.

[0079] When the cartridge 10 leaves the factory, the liquid-sealing member is in the liquid-sealing position to seal the liquid storage cavity 110 and prevent the e-liquid from leaking. The sliding socket part 131 of the liquid-sealing member is hermetically connected to the ventilation pipe 111. On the one hand, it guides the sliding of the liquid-sealing member, and on the other hand, it can also prevent the e-liquid from entering the ventilation pipe 111 through the connection between the sliding socket part 131 and the ventilation pipe 111. In this embodiment, a plurality of annular protrusions (not shown in the figure) are provided on the inner wall of the sliding socket part 131 along the circumferential direction of the sliding socket part 131, thereby increasing the friction between the sliding socket part 131 and the ventilation pipe 111, and effectively preventing the liquid-sealing member from easily leaving the liquid-sealing position and causing e-liquid leakage when the cartridge 10 shakes.

[0080] Please refer to Figure 3 、 Figure 4 In one embodiment, the cartridge 10 further includes a bottom cover 14. The bottom cover 14 is installed at the lower end of the outer shell 11. The upper end surface of the bottom cover 14 fits against the lower end surface of the seal 12, thereby fixing and supporting the seal 12 and preventing the seal 12 from deforming and causing e-liquid leakage. At least one liquid injection hole 143 is provided on the bottom cover 14. During liquid injection, the liquid injection needle passes through the liquid injection hole 143, pierces the seal 12, and extends into the liquid storage cavity 110 for liquid injection. When the liquid injection needle is pulled out, the seal 12 can automatically restore the seal of the liquid storage cavity 110. In this embodiment, a sealing cover 141 is rotatably installed on the lower end surface of the bottom cover 14. A sealing plug 142 protrudes corresponding to the liquid injection hole 143 on the sealing cover 141. Rotating the sealing cover 141 can make the sealing plug 142 close or open the liquid injection hole 143. When the sealing plug 142 closes the liquid injection hole 143, it can further prevent the e-liquid from leaking through the liquid injection hole 143. When the sealing plug 142 opens the liquid injection hole 143, it is convenient for the user to perform the liquid injection operation. In this embodiment, the bottom cover 14 is snap-connected to the outer shell 11. Understandably, the bottom cover 14 and the outer shell 11 can also be connected in a detachable manner such as plugging or threaded connection.

[0081] Understandably, in other embodiments not shown, a liquid injection port corresponding to the liquid injection hole 143 is provided on the seal 12. During liquid injection, the liquid injection needle passes through the liquid injection hole 143 and the liquid injection port in sequence and then extends into the liquid storage cavity 110 for liquid injection.

[0082] Please refer to Figure 5 、 Figure 6, the upper end of the atomizing head 20 sequentially passes through the bottom cover 14 and the seal 12 and then extends into the liquid-sealing member and is clamped with the liquid-sealing portion. The atomizing head 20 is linked with the liquid-sealing member. The atomizing head 20 includes an atomizing tube 21, a heating component (not shown in the figure) arranged in the atomizing tube 21, and a first electrode 24 installed at one end of the atomizing tube 21. The atomizing tube 21 is generally a hollow cylindrical structure with both ends penetrating. The inner cavity of the atomizing tube 21 forms an atomizing chamber 210. A liquid inlet 211 is formed on the outer wall of the atomizing tube 21, and the liquid inlet 211 is communicated with the atomizing chamber 210. In this embodiment, there are two liquid inlets 211, which are oppositely arranged on the outer wall of the atomizing tube 21. It can be understood that in other embodiments, the number of the liquid inlets 211 can be one, three or more. Optionally, the liquid inlet 211 is formed on the side wall of the atomizing tube 21. The atomizing tube 21 is matched with the jack 121, and the upper end of the atomizing tube 21 extends into the liquid-sealing member 13 through the jack 121. In this embodiment, the heating component is arranged along the axis of the atomizing head 20. Specifically, the heating component includes a liquid-absorbing member 22 and a heating element 23 that are in contact with each other. The liquid-absorbing member 22 and the heating element 23 are both accommodated in the atomizing chamber 210. The liquid-absorbing member 22 has the ability to absorb the smoke liquid. After the heating element 23 is powered on, it can generate heat. During use, after the heating element 23 is powered on, it heats the smoke liquid absorbed on the liquid-absorbing member 22, and the smoke liquid generates smoke under the heating of the heating element 23. The smoke fills the atomizing chamber 210. The liquid-absorbing member 22 is generally a hollow cylindrical structure with both ends penetrating. The liquid-absorbing member 22 is attached to the inner wall of the atomizing tube 21 corresponding to the liquid inlet 211. The heating element 23 is accommodated in the inner cavity of the liquid-absorbing member 22. The liquid-absorbing member 22 is cotton, and the heating element 23 is a spiral heating wire. It can be understood that in other embodiments not shown, the liquid-absorbing member 22 can also be a fiber rope, a porous ceramic, a porous graphite, etc., and the heating element 23 can also be a heating sheet, a heating mesh or an electromagnetic induction heating device, etc. In addition, alternatively, the heating component can also be an ultrasonic atomizing device, etc., which is not limited here.

[0083] The first electrode 24 is generally a hollow tubular structure with both ends penetrating. The first electrode 24 is installed at the lower end of the atomizing tube 21 and is communicated with the atomizing chamber 210. One lead of the heating element 23 is electrically connected to the first electrode 23, and the other lead of the heating element 23 is electrically connected to the atomizing tube 21. In this way, when the positive and negative electrodes of the battery assembly 30 are respectively electrically connected to the first electrode 24 and the atomizing tube 21, the function of the battery assembly 30 supplying power to the heating element 23 is realized. In order to achieve electrical isolation and avoid short circuit, an insulating member (not shown in the figure) is clamped between the first electrode 24 and the atomizing tube 21. The material of the insulating member includes but is not limited to silica gel or rubber.

[0084] In addition, please refer to again Figure 6, a first engaging portion 133 is provided on the inner wall of the liquid sealing portion 13 of the liquid sealing member, and a second engaging portion 212 capable of engaging with the first engaging portion 133 is provided on the outer wall of the atomizing tube 21. When the liquid sealing member is in the liquid sealing position, the atomizing head 20 is inserted upward. The upper end of the atomizing head 20 passes upward through the jack 121 and then gradually extends into the liquid sealing member until the upper end of the atomizing head 20 abuts against the inner wall of the liquid sealing member. At this time, when the atomizing head 20 is further pushed upward, the liquid sealing member 13 will move upward together under the drive of the atomizing head 20. When the liquid sealing member moves to a position where the upper end surface of the liquid sealing portion 13 abuts against the lower end surface of the air vent pipe 111 and stops moving, the liquid sealing member is in the liquid discharging position. It should be noted that during the upward movement of the atomizing head 20, the second engaging portion 212 of the atomizing head 20 can move above the first engaging portion 133 after passing over the first engaging portion 133. When the liquid sealing member is in the liquid discharging position, the liquid inlet 211 of the atomizing head 20 extends at least partially into the liquid storage cavity 110 and is in communication with the liquid storage cavity 110, so that the smoke liquid in the liquid storage cavity 110 flows into the atomizing cavity 210 through the liquid inlet 211, and the user can perform a suction operation.

[0085] In addition, in other embodiments not shown, a liquid passing port is provided on the side wall of the bottom of the liquid sealing portion 13 of the liquid sealing member. When the liquid sealing member is in the liquid sealing state, the lower end of the liquid sealing portion 13 is inserted into the jack 121, and the liquid passing port is closed by the sealing member 12. When the liquid sealing member moves upward under the drive of the atomizing head 20, the lower end of the liquid sealing portion 13 is still inserted into the jack 121, but the liquid passing port moves upward, so that the liquid passing port extends into the liquid storage cavity 110 after separating from the sealing member 12. At this time, the smoke liquid in the liquid storage cavity 110 enters the atomizing cavity 210 after passing through the liquid passing port.

[0086] When the user finishes sucking, the atomizing head 20 is pulled out relative to the cartridge 10. Due to the engaging relationship between the first engaging portion 133 and the second engaging portion 212, the liquid sealing member can move downward under the drive of the atomizing tube 21 and finally return to Figure 4 the shown liquid sealing position, so that the smoke liquid in the liquid storage cavity 110 cannot flow out, thereby achieving the effect that the liquid storage cavity 110 is automatically sealed when the atomizing head 20 is pulled out.

[0087] In this embodiment, the first clamping portion 133 is an annular protrusion protruding from the inner wall of the liquid sealing portion 13 along the circumferential direction of the liquid sealing member, and the second clamping portion 212 is an annular protrusion protruding from the outer wall of the atomizing tube 21 along the circumferential direction of the atomizing tube 21. It can be understood that in other embodiments not shown, one of the first clamping portion 133 and the second clamping portion 212 is an annular protrusion, and the other of the first clamping portion 133 and the second clamping portion 212 is an annular groove, and the clamping relationship between the liquid sealing member and the atomizing tube 21 can also be achieved. It can be understood that in other embodiments not shown, the first clamping portion 133 and the second clamping portion 212 can also adopt other shaped clamping structures, such as two pairs of protrusions and elastic pieces arranged oppositely, which are not limited.

[0088] Please refer to again Figure 4 , the cartridge 10 further includes a support sleeve 15. The support sleeve 15 is wrapped around the outside of the liquid sealing portion 13 of the liquid sealing member. The support sleeve 15 is made of a hard material. Due to the supporting effect of the support sleeve 15 on the liquid sealing portion 13, it can prevent the situation that the first clamping portion 133 and the second clamping portion 212 are not tightly clamped, resulting in the first clamping portion 133 and the second clamping portion 212 being easily disengaged and thus affecting the movement of the liquid sealing member. In this embodiment, the support sleeve 15 is made of stainless steel material, but it can also be other hard materials without limitation.

[0089] Please refer to again Figure 5 , the battery assembly 30 includes a battery case 31 and a battery cover plate 32 and a battery 33 received in the battery case 31. The battery case 31 is generally a hollow cylindrical structure with an opening at the upper end. The battery cover plate 32 is in a plate-like structure and is arranged along the radial direction of the battery case 31. Thus, the battery cover plate 32 divides the inner cavity of the battery case 31 into a battery installation cavity (not shown in the figure) located below the battery cover plate 32 and a cartridge installation cavity (not shown in the figure) located above the battery cover plate 32. Among them, the battery 33 is received in the battery installation cavity, and the lower end of the cartridge 10 is inserted into the cartridge installation cavity.

[0090] The atomizing head 20 is detachably connected to the battery assembly 30. Specifically, the lower end of the atomizing tube 21 is threadedly connected to the battery cover plate 32. A second electrode 321 is installed on the lower end face of the battery cover plate 32. The first electrode 24 contacts and is electrically connected to the second electrode 321. One of the positive and negative electrodes of the battery 33 is electrically connected to the second electrode 321, and the other of the positive and negative electrodes of the battery 33 is electrically connected to the battery cover plate 32, thereby realizing the function of the battery 33 supplying power to the atomizing head 20. An air inlet channel 322 is radially formed on the battery cover plate 32 along the radial direction of the battery cover plate 32. An air inlet hole 311 communicating with the outside atmosphere is formed on the battery case 31. One end of the air inlet channel 322 communicates with the inner cavity of the first electrode 24, and the other end of the air inlet channel 322 is connected to the air inlet hole 311. Thus, external gas enters the atomizing cavity 210 after passing through the air inlet hole 311, the air inlet channel 322, and the inner cavity of the first electrode 24 in sequence and mixes with the generated smoke. The mixed gas enters the user's mouth after passing through the ventilation pipe 111 and the smoking port 112 in sequence. It can be understood that in other embodiments, the gas flow path is not limited to this one and is not limited.

[0091] In addition, please refer to again Figure 6 , a first engaging portion 113 is provided on the outer wall of the housing 11, and a positioning portion 312 cooperating with the first engaging portion 113 is provided on the inner wall of the battery case 31. When the atomizing head 20 is gradually inserted into the cartridge 10, the cartridge 10 is gradually inserted into the cartridge mounting cavity until the liquid sealing member moves from the liquid sealing position to the liquid discharging position driven by the atomizing head 20, the positioning portion 312 and the first engaging portion 113 are engaged with each other. At this time, the battery assembly 30 and the cartridge 10 are stably connected, preventing the battery assembly 30 from separating from the cartridge 10, and the user can perform a suction operation. After the suction is completed, the atomizing head 20 is pulled out. When the liquid sealing member moves from the liquid discharging position to the liquid sealing position driven by the atomizing head 20, the positioning portion 312 and the first engaging portion 113 are disengaged from each other. At this time, the battery assembly 30 together with the atomizing head 20 can be further pulled off the cartridge 10. The cartridge 10 separated from the atomizing head 20 seals the liquid storage cavity 110 under the action of the liquid sealing member, and the e-liquid cannot flow out, thereby facilitating the carrying and transportation of the cartridge 10. In this embodiment, the first engaging portion 113 is a groove recessed on the outer wall of the housing 11, and the positioning portion 312 is a protrusion protruding on the inner wall of the battery case 31. It can be understood that in other embodiments not shown, the first engaging portion 113 is a protrusion protruding on the outer wall of the housing 11, and the positioning portion 312 is a groove recessed on the inner wall of the battery case 31.

[0092] Please refer to Figure 1 , Figure 6, the electronic cigarette according to the first embodiment of the present invention further includes a cigarette ignition device 50 and a control board 70. Among them, the atomizing head 20, the battery assembly 30, and the cigarette ignition device 50 are all electrically connected to the control board 70. When the user triggers the cigarette ignition device 50, the cigarette ignition device 50 generates a start signal and transmits it to the control board 70. When the control board 70 receives this signal, it controls the battery assembly 30 to supply power to the atomizing head 20. The cigarette ignition device 50 can be a switch or an airflow sensor.

[0093] It can be understood that in other embodiments not shown, the liquid sealing member may also move without relying on the pushing or clamping action of the atomizing head 20 to close or open the liquid storage cavity 110. Specifically, an elastic member (for example, a spring) may be provided between the upper end of the liquid sealing member and the inner end surface of the outer shell 11. The liquid sealing member can compress the elastic member and move upward along the axial direction of the ventilation pipe 111, so that the lower end of the liquid sealing member is separated from the upper end of the sealing member 12. At this time, the liquid storage cavity 110 is opened, and the e-liquid is also communicated with the atomizing head 20. When the liquid sealing member gets rid of the pushing action of the atomizing head 20, the liquid sealing member can reset under the action of the elastic member, so that the lower end of the liquid sealing member is hermetically abutted against the upper end of the sealing member 12. At this time, the liquid storage cavity 110 is closed, and the e-liquid cannot flow out.

[0094] For the atomizer provided by the first embodiment of the present invention, when the atomizing head 20 is connected to the cartridge 10, the liquid sealing member moves under the drive of the atomizing head 20 to open the liquid storage cavity 110, so that the liquid inlet 211 is communicated with the liquid storage cavity 110, and the user can perform a suction operation; when the atomizing head 20 is separated from the cartridge 10, the liquid sealing member moves under the drive of the atomizing head 20 to close the liquid storage cavity 110. While realizing the automatic sealing of the cartridge 10, the e-liquid is also isolated from the atomizing head 20, preventing the situation that the life of the atomizing head 20 is shortened due to the e-liquid always contacting the atomizing head 20 and the poor smoking taste caused by the deterioration of the e-liquid, and greatly improving the user experience.

[0095] The electronic cigarette provided by the first embodiment of the present invention has the same technical effects as the above atomizer because it has all the technical features of the above atomizer.

[0096] Embodiment Two

[0097] Please refer to Figures 7 - 9 , the difference between the electronic cigarette provided by the second embodiment of the present invention and the electronic cigarette of the first embodiment is that: in this embodiment, a second engaging portion 114 cooperating with the positioning portion 312 is further provided on the outer wall of the outer shell 11.

[0095]

[0098] Specifically, please refer to Figure 7, the second engaging portion 114 is located below the first engaging portion 113. As described in the first embodiment above, when the liquid sealing member is driven by the atomizing head 20 to move from the liquid sealing position to the liquid discharging position, the positioning portion 312 and the first engaging portion 113 are engaged with each other, thereby realizing the function of stably connecting the battery assembly 30 and the cartridge 10. Please refer to Figure 9 , in this embodiment, when the liquid sealing member is driven by the atomizing head 20 to move from the liquid discharging position to the liquid sealing position, after the positioning portion 312 is disengaged from the first engaging portion 113, it further engages with the second engaging portion 114. At this time, the battery assembly 30 and the cartridge 10 are stably connected again by the engaging relationship between the positioning portion 312 and the second engaging portion 114. At this time, the liquid storage cavity 110 is in a closed state, and the e-liquid cannot leak, which is convenient for the user to carry the entire electronic cigarette. At the same time, the top of the atomizing tube 21 is in contact with the inner end surface of the liquid sealing member. Please refer to Figure 8 , when the positioning portion 312 is engaged with the second engaging portion 114 and the atomizing head 20 is continuously pulled out, the positioning portion 312 can be disengaged from the second engaging portion 114, and finally the cartridge 10, the atomizing head 20 and the battery assembly 30 are separated. The cartridge 10 separated from the atomizing head 20 closes the liquid storage cavity 110 under the action of the liquid sealing member, and the e-liquid cannot flow out, that is, the e-liquid is fluidly cut off from the atomizing head 20, thereby facilitating the carrying and transportation of the cartridge 10.

[0099] In this embodiment, the liquid sealing member is pushed upward by the upper end of the atomizing tube 21. In other embodiments, it can also move upward by relying on the engaging action between the atomizing tube 21 and the liquid sealing member.

[0100] In this embodiment, both the first engaging portion 113 and the second engaging portion 114 are grooves protruding from the outer wall of the housing 11, and the positioning portion 312 is a protrusion protruding from the inner wall of the battery case 31. It can be understood that in other embodiments not shown, both the first engaging portion 113 and the second engaging portion 114 are protrusions protruding from the outer wall of the housing 11, and the positioning portion 312 is a groove recessed in the inner wall of the battery case 31.

[0101] In addition, please refer to again Figure 9, when the positioning portion 312 is engaged with the second engaging portion 114, the axial distance between the lower end surface of the ventilation pipe 111 and the upper end surface of the liquid sealing portion 13 of the liquid sealing member is equal to the axial distance between the first engaging portion 113 and the second engaging portion 114. Thus, when the positioning portion 312 moves to be engaged with the first engaging portion 113, the lower end surface of the ventilation pipe 111 just abuts against the upper end surface of the liquid sealing portion 13, thereby restricting the further upward movement of the liquid sealing member and playing a reminding role in whether the atomizing head 20 is installed in place. In this embodiment, an annular flange 115 is convexly provided on the outer wall of the housing 11 along the circumferential direction of the housing 11. When the positioning portion 312 is engaged with the second engaging portion 114, the axial distance between the lower end surface of the annular flange 115 and the upper end surface of the battery housing 31 is equal to the axial distance between the first engaging portion 113 and the second engaging portion 114. Thus, when the positioning portion 312 moves to be engaged with the first engaging portion 113, the lower end surface of the annular flange 115 abuts against the upper end surface of the battery housing 31, further playing a limiting role. In addition, when the positioning portion 312 is engaged with the second engaging portion 114, the axial distance between the upper end surface of the battery cover plate 32 and the lower end surface of the bottom cover 14 is greater than or equal to the axial distance between the lower end surface of the ventilation pipe 111 and the upper end surface of the liquid sealing portion 13 to provide a movable space for the bottom cover 14 relative to the battery cover plate 32 when the liquid sealing member moves from the liquid sealing position to the liquid discharging position. Optionally, in this embodiment, the axial distance between the lower end surface of the ventilation pipe 111 and the upper end surface of the liquid sealing portion 13 is 4 mm, and the axial distance between the upper end surface of the battery cover plate 32 and the lower end surface of the bottom cover 14 is 4.5 mm.

[0102] For the electronic cigarette provided in the second embodiment of the present invention, when the positioning portion 312 moves to be engaged with the second engaging portion 114, the liquid sealing member is in the liquid sealing position, the smoke liquid is isolated from the atomizing head 20, and at the same time, a stable connection is maintained between the battery assembly 30 and the cartridge 10. The cartridge 10, the atomizing head 20 and the battery assembly 30 form an integral whole, which is convenient for the user to carry. The user can isolate the smoke liquid from the atomizing head 20 without completely disassembling the cartridge 10 from the atomizing assembly, and the operation is convenient, improving the user experience.

[0103] Embodiment Three

[0104] Please refer to Figures 10 - 13 , the difference between the electronic cigarette provided in the third embodiment of the present invention and the electronic cigarette in the second embodiment lies in that: in this embodiment, the electronic cigarette further includes a switch device 40 and a movable member 60.

[0105] Specifically, the switch device 40, the cigarette lighter device 50, and the movable member 60 cooperate with each other. When the movable member 60 is moved until it abuts against the switch device 40, the cigarette lighter device 50 is enabled. That is, at this time, operating the cigarette lighter device 50 can make the circuit between the battery assembly 30 and the atomizing head 20 in a conducting state, so that the battery assembly 30 can supply power to the atomizing head 20 to drive the atomizing head 20 to work and atomize the e-liquid. When the movable member 60 is moved until it separates from the switch device 40, the cigarette lighter device 50 is locked. That is, regardless of whether the cigarette lighter device 50 is operated, the circuit between the battery assembly 30 and the atomizing head 20 is in an open state.

[0106] In this embodiment, the electronic cigarette further includes a control board 70. Among them, the atomizing head 20, the battery assembly 30, the switch device 40, and the cigarette lighter device 50 are all electrically connected to the control board 70. When the movable member 60 is moved until it abuts against the switch device 40, the switch device 40 generates a trigger signal and feeds the trigger signal back to the control board 70. At this time, the cigarette lighter device 50 in the enabled state can generate a start signal under the operation of the user and feed it back to the control board 70. When the control board 70 receives the start signal, the control board 70 controls the atomizing head 20 to start, that is, controls the circuit between the atomizing head 20 and the battery assembly 30 to conduct. When the movable member 60 is moved until it separates from the switch device 40, the trigger signal is interrupted, and the control board 70 locks the cigarette lighter device 50. The cigarette lighter device cannot send a start signal or even if it sends a signal to the control board 70, the control board 70 does not send a signal to make the atomizing head 20 work. The cigarette lighter device 50 can be a switch or a sensor. Optionally, it is an airflow sensor or a pressure sensor or other sensors. It can be understood that the control board 70 can also be replaced by other electronic components with control functions, such as a controller. In one embodiment, the controller is electrically connected to the atomizing head, the cigarette lighter device 50, and the switch device, and the controller is used to control the atomizing head to work after receiving the trigger signal and the start signal.

[0107] It can be understood that in other embodiments not shown, it can also be that the atomizing head 20, the battery assembly 30, the switch device 40, and the cigarette lighter device 50 are connected in series, and the control board 70 is omitted. When the movable member 60 is moved until it abuts against the switch device 40, the switch device 40 closes, and the cigarette lighter device 50 is enabled. When the cigarette lighter device 50 is also closed by operating the cigarette lighter device 50, the circuit between the battery assembly 30 and the atomizing head 20 is in a conducting state. When the movable member 60 is moved until it separates from the switch device 40, the switch device 40 disconnects. Obviously, at this time, regardless of whether the cigarette lighter device 50 is operated to the closed or open state, the circuit between the battery assembly 30 and the atomizing head 20 is in an open state. Both the switch device 40 and the cigarette lighter device 50 are switches with on / off functions.

[0108] The cigarette lighter device 50 is installed on the battery case 31, the control board 70 is installed in the battery installation cavity and is located between the battery 33 and the battery cover plate 32. The switch device 40 is installed on the upper end surface of the control board 70. The movable member 60 is movably inserted through the battery cover plate 32 and is located directly above the switch device 40. The upper end of the movable member 60 extends to the upper end surface of the battery cover plate 32, and the lower end of the movable member 60 extends to the lower end surface of the battery cover plate 32. Moving the movable member 60 upward can separate the lower end of the movable member 60 from the switch device 40, and moving the movable member 60 downward can make the lower end of the movable member 60 abut against the switch device 40.

[0109] Please refer to again Figure 11 When the positioning portion 312 moves to engage with the second engaging portion 114, the upper end of the movable member 60 is separated from the lower end surface of the bottom cover 14, and the movable member 60 is in a natural state, so that the lower end of the movable member 60 is separated from the switch device 40. At this time, the cigarette lighter device 50 is locked, and the circuit between the battery assembly 30 and the atomizing head 20 is in an open state regardless of whether the cigarette lighter device 50 is operated. Please refer to again Figure 12 When the positioning portion 312 moves to engage with the first engaging portion 113, the upper end of the movable member 60 abuts against the lower end surface of the bottom cover 14, and the movable member 60 is in a pressed state, so that the lower end of the movable member 60 abuts against the switch device 40. At this time, the cigarette lighter device 50 is enabled, and operating the cigarette lighter device 50 can make the circuit between the battery assembly 30 and the atomizing head 20 in a conductive state, so that the battery assembly 30 can supply power to the atomizing head 20 to drive the atomizing head 20 to atomize the e-liquid. When the positioning portion 312 disengages from the first engaging portion 113 and then engages with the second engaging portion 114, the movable member 60 can be reset so that the lower end of the movable member 60 is separated from the switch device 40, and the cigarette lighter device 50 is locked again and returns to Figure 11 the state shown.

[0110] In addition, in an embodiment not shown, when the positioning portion 312 moves to engage with the second engaging portion 114, the upper end of the movable member 60 is separated from the lower end surface of the bottom cover 14, and the movable member 60 is in a natural state. At this time, the lower end of the movable member 60 can also be abutted against the switch device 40, but the switch device 40 is not pressed, so the switch device 40 is not triggered. When the positioning portion 312 moves to engage with the first engaging portion 113, the movable member 60 will press the switch device 40 under the pushing of the bottom cover 14, thereby triggering the switch device 40. Further, the switch device 40 is an elastic switch button.

[0111] In this embodiment, the movable member 60 is a spring pin. Optionally, please refer to Figure 13, a through hole 323 is formed in the battery cover plate 32. The movable member 60 is rod-shaped and movably passes through the through hole 323. A first abutting edge 3231 protrudes radially inward from the hole wall of the through hole 323 along the radial direction of the through hole 323. A second abutting edge 601 protrudes radially outward from the outer wall of the movable member 60 along the radial direction of the movable member 60. A reset member 61 is telescopically arranged between the first abutting edge 3231 and the second abutting edge 601. Thus, the movable member 60 can compress the reset member 61 and move downward under the pushing of the bottom cover 14 to press the switch device 40. When the pushing action of the bottom cover 14 on the movable member 60 is removed, the movable member 60 can move upward and reset under the elastic force of the reset member 61 and then disengage from the switch device 40. In this embodiment, the reset member 61 is a spring. It can be understood that in other embodiments not shown, the reset member 61 can also be a rigid and elastic element such as a stainless steel shrapnel or a copper shrapnel.

[0112] In the electronic cigarette provided in the third embodiment of the present invention, only when the cartridge 10 and the battery assembly 30 are in the position where the positioning portion 312 is engaged with the first engaging portion 113, can the user operate the cigarette lighting device 50 to make the circuit between the battery assembly 30 and the atomizing head 20 in a conducting state, and then perform the operation of sucking the smoke, preventing children from easily triggering the cigarette lighting device 50 and causing the situation of accidentally sucking the smoke or scalding children, playing a safety protection role for children, and thus playing an anti-misoperation function. In addition, when the positioning portion 312 is engaged with the second engaging portion 114, at this time, the e-liquid and the atomizing head 20 are isolated from each other, and the e-liquid cannot leak, which is convenient for carrying. Moreover, even if the cigarette lighting device 50 is accidentally triggered during the carrying process, the circuit between the battery assembly 30 and the atomizing head 20 cannot be conducted, avoiding the occurrence of dry burning, and further preventing the atomizing head 20 from being damaged.

[0113] Embodiment Four

[0114] Please refer to Figures 14 - 22 , the difference between the electronic cigarette provided in the fourth embodiment of the present invention and the electronic cigarette in the first embodiment lies in that: the air intake mode in this embodiment is different, which is mainly manifested in the different structures of the cartridge 10 and the atomizing head 20.

[0115] Specifically, please refer to Figure 20, in this embodiment, the difference in the structure of the cartridge 10 from that of the first embodiment lies in that a fixing tube 116 is formed by the top wall of the outer shell 11 extending downward along the axis of the outer shell 11. The fixing tube 116 is sleeved outside the air pipe 111. Among them, the space surrounded between the inner wall of the fixing tube 116 and the outer wall of the air pipe 111 constitutes the air inlet chamber 1161, and the space surrounded between the outer wall of the fixing tube 116 and the inner wall of the outer shell 11 constitutes the liquid storage chamber 110. An air inlet passage 1162 is radially formed in the wall body of the cartridge 10 along the radial direction of the cartridge 10. One end of the air inlet passage 1162 is communicated with the outside atmosphere, and the other end of the air inlet passage 1162 is communicated with the air inlet chamber 1161. In addition, a liquid outlet gap (not shown in the figure) is left between the lower end surface of the fixing tube 116 and the upper end surface of the sealing member 12. The liquid sealing member 13 is slidably received in the fixing tube 116. Sliding the liquid sealing member 13 upward can make the liquid sealing member 13 open the liquid outlet gap. At this time, the e-liquid in the liquid storage chamber 110 can flow out through the liquid outlet gap; please refer to Figure 24 , sliding the liquid sealing member 13 downward can make the liquid sealing member close the liquid outlet gap. At this time, the liquid storage chamber 110 is closed and the e-liquid cannot flow out.

[0116] Please refer to Figures 16 - 18 , in this embodiment, the atomizing head 20 includes an outer sleeve 25, an inner sleeve 26 and a connecting member 27 received in the outer sleeve 25, a heating assembly (not shown in the figure) provided in the inner sleeve 26, and a first electrode 24 installed at one end of the inner sleeve 26.

[0117] The outer sleeve 25 and the inner sleeve 26 are both roughly hollow cylindrical structures with both ends connected. The inner cavity of the inner sleeve 26 forms an atomizing chamber 210. The outer wall of the inner sleeve 26 is closely fitted with the inner wall of the outer sleeve 25 to achieve a sealing effect. Two notches 261 are relatively opened along the axial direction of the inner sleeve 26 on the outer wall of the inner sleeve 26. The notches 261 run through the upper end face of the inner sleeve 26. Due to the presence of the notches 261, a ventilation gap 251 is formed between the outer sleeve 25 and the inner sleeve 26. A first air inlet 262 is opened on the bottom wall of the notch 261. The first air inlet 262 is connected to the atomizing chamber 210 and the ventilation gap 251. The outer wall of the inner sleeve 26 is staggered with the notches 261 and is also provided with a liquid inlet 211 connected to the atomizing chamber 210. A connecting port 252 connected to the liquid inlet 211 is opened on the side wall of the outer sleeve 25. The connector 27 is a roughly sleeve-like structure with two through-holes. It is mounted on the upper end of the inner sleeve 26. A second air inlet hole 271 is defined on the outer wall of the connector 27 along its axial direction. The upper end of the second air inlet hole 271 extends through the upper end surface of the connector 27, while the lower end of the second air inlet hole 271 communicates with the ventilation gap 251. Furthermore, to prevent liquid from leaking between the outer sleeve 25 and the inner sleeve 26, a sealing element (not shown) is interposed between the outer sleeve 25 and the inner sleeve 26 around the liquid inlet 211. The sealing element is made of a sealing material, including but not limited to silicone or rubber.

[0118] The first electrode 24 is installed at the lower end of the inner sleeve 26. The heating component and the arrangement are the same as those in the first embodiment and will not be described again here.

[0119] Also, see Figure 21 The inner wall of the liquid sealing member 13 is provided with a first locking portion 133, and the outer wall of the outer sleeve 25 is provided with a second locking portion 212 that can be engaged with the first locking portion 133. The structure and arrangement of the first locking portion 133 and the second locking portion 212 are the same as those in the first embodiment and will not be repeated here. Figure 20, when the atomizing head 20 is inserted into the cartridge 10, the top of the atomizing head 20 pushes against the inner end face of the liquid-sealing member 13, thereby driving the liquid-sealing member 13 to move upward. Eventually, the liquid-sealing member 13 opens the liquid outlet notch, and the communication port 252 is at least partially in communication with the liquid storage chamber 110. At this time, the liquid-sealing member 13 is in the liquid-discharging position, and the e-liquid in the liquid storage chamber 110 can sequentially enter the atomizing chamber 210 through the liquid outlet notch, the communication port 252, and the liquid inlet 211, thereby realizing the communication between the e-liquid and the atomizing head 20. In addition, at this liquid-discharging position, the lower end of the ventilation pipe 111 is inserted into the connector 27. The user can perform a suction operation. During suction, external gas sequentially enters the atomizing chamber 210 through the air inlet passage 1162, the air inlet chamber 1161, the second air inlet hole 271, the ventilation gap 251, and the first air inlet hole 262 and mixes with the smoke. The mixed gas sequentially enters the user's mouth through the inner cavity of the connector 27, the inner cavity of the ventilation pipe 111, and the smoking port 112. During the above process, the external gas flows through the atomizing head 20 before entering the atomizing chamber 210, so that part of the heat on the atomizing head 20 can be transferred to the gas entering the electronic cigarette. In this way, it is ensured that the air flow before entering the atomizing chamber 210 already has a relatively high temperature, improving the atomization efficiency and saving energy. In addition, there is no need to provide an air inlet hole at the bottom of the atomizing head 20, which is easy to process and also prevents the e-liquid from leaking through this air inlet hole.

[0120] Please refer to Figure 22 , after the user finishes suction and pulls out the atomizing head 20 relative to the cartridge 10, due to the engagement relationship between the first engaging portion 133 and the second engaging portion 212, the liquid-sealing member 13 is driven to move downward together with the atomizing head 20. Eventually, the liquid-sealing member 13 closes the liquid outlet notch. At this time, the liquid-sealing member 13 is in the liquid-sealing position, and the e-liquid in the liquid storage chamber 110 cannot flow out, thus realizing the effect of separating the e-liquid from the atomizing head 20.

[0121] In addition, in this embodiment, the air inlet passage 322 of the battery cover 32 on the battery assembly 30 is omitted, and the rest of the structure is the same as that in the first embodiment, which will not be elaborated here. At the same time, the fixed pipe the fixed pipe 116 can also be omitted in this embodiment. At this time, the liquid-sealing member 13 adopts the same structure as that in the first embodiment, and can also achieve the above effects.

[0122] Embodiment Five

[0123] Please refer to Figures 23 - 25 , the difference between the electronic cigarette provided in the fifth embodiment of the present invention and the electronic cigarette in the first embodiment lies in that: in this embodiment, the heating assembly is arranged along the radial direction of the atomizing head 20.

[0124] Specifically, the cartridge 10 includes a housing 11, a seal 12, a liquid-sealing member 13, a sealing cover 18, a liquid-blocking sleeve 19, and a liquid-sealing member 13. Among them, a liquid storage cavity 110 is provided on the housing 11. The seal 12 is installed at the lower end of the housing 11. The sealing cover 18 is installed at the lower end of the air pipe 111 of the housing 11. The liquid-blocking sleeve 19 is connected between the sealing cover 18 and the seal 12. The liquid-sealing member 13 is movably received in the liquid-blocking sleeve 19.

[0125] In this embodiment, the sealing cover 18 is generally a tapered hollow structure with both ends penetrating. The upper end of the sealing cover 18 is sleeved on the lower end of the air pipe 111. The liquid-blocking sleeve 19 is generally a tubular structure with both ends penetrating. And the upper end of the liquid-blocking sleeve 19 is sealed and inserted into the lower end of the sealing cover 18. The lower end of the liquid-blocking sleeve 19 is sealed and inserted into the slot 122 of the seal 12. Two oppositely arranged liquid inlet holes 161 are formed on the side wall of the liquid-blocking sleeve 19. The liquid inlet holes 161 are communicated with both the liquid storage cavity 110 and the inner cavity of the liquid-blocking sleeve 19. Liquid flow holes 134 are formed on the side wall of the liquid-sealing member 13 corresponding to the liquid inlet holes 161. Sliding the liquid-sealing member 13 upward relative to the liquid-blocking sleeve 19 can align and communicate the liquid flow holes 134 with the liquid inlet holes 161, so that the smoke liquid in the liquid storage cavity 110 can flow out successively through the liquid inlet holes 161 and the liquid flow holes 134. Sliding the liquid-sealing member 13 downward relative to the liquid-blocking sleeve 19 can misalign the liquid flow holes 134 with the liquid inlet holes 161, thereby closing the liquid storage cavity 110, and the smoke liquid in the liquid storage cavity 110 cannot flow out.

[0126] In this embodiment, the atomizing head 20 includes an atomizing tube 21 having an atomizing cavity 210, an atomizing base 28 installed at the lower end of the atomizing tube 21, and a heating component received in the atomizing cavity 210.

[0127] The atomizing tube 21 is roughly a cylindrical structure with both ends through, and the atomizing chamber 210 is formed by the inner cavity of the atomizing tube 21. The atomizing base 28 is sealed and installed in the lower end of the atomizing tube 21. The atomizing base 28 is provided with an air inlet 311, which is connected to the outside atmosphere and the atomizing chamber 210. Two oppositely arranged liquid inlets 211 are provided on the side wall of the atomizing tube 21 corresponding to the liquid flow holes 134, and the liquid inlet 211 is connected to the atomizing chamber 210. A first electrode column 281 and a second electrode column 282 are installed on the atomizing base 28. The heating assembly includes a heating element 23 and a liquid absorbing element (not shown) in contact with each other. One pin of the heating element 23 is electrically connected to the first electrode column 281, and the other pin of the heating element 23 is electrically connected to the second electrode column 282. In addition, one of the positive and negative electrodes of the battery assembly (not shown) is electrically connected to the first electrode column 281, and the other of the positive and negative electrodes of the battery assembly 30 is electrically connected to the second electrode column 282, thereby enabling the battery assembly to supply power to the heating element 23. One end of the liquid absorbing member extends into one of the liquid inlets 211, and the other end of the liquid absorbing member extends into the other liquid inlet 211. In this embodiment, the heating element 23 and the liquid absorbing member are arranged radially along the atomizing tube 21.

[0128] In addition, a first locking portion 133 is provided on the inner wall of the liquid sealing member 13, and a second locking portion 212 capable of engaging with the first locking portion 133 is provided on the outer wall of the atomizing tube 21. Figure 25 When the atomizer head 20 is inserted into the cigarette cartridge 10, the atomizer head 20 passes through the sealing member 12 and is inserted into the liquid sealing member 13. Finally, the liquid sealing member 13 moves upward under the pushing action of the atomizer head 20 until it abuts against the inner end surface of the sealing cover 18. At this time, the liquid flow hole 134 is aligned with the liquid inlet hole 161 and the liquid inlet port 211 and is connected. At this time, the liquid sealing member 13 is in the liquid discharge position. The smoke liquid in the liquid storage chamber 110 can enter the atomizer head 20 through the liquid inlet hole 161, the liquid flow hole 134 and the liquid inlet port 211 in sequence, thereby connecting the smoke liquid and the atomizer head 20. In this liquid discharge position, the user can perform the inhalation operation. Figure 25 When the atomizer head 20 is removed from the cigarette cartridge 10, the engagement between the first engaging portion 133 and the second engaging portion 212 causes the liquid sealing member 13 to move downward along with the atomizer head 20, ultimately causing the liquid flow hole 134 and the liquid inlet hole 161 to be offset from each other. At this point, the liquid sealing member 13 is in the liquid sealing position, and the liquid inlet hole 161 is closed by the sidewall of the liquid sealing member 13, isolating the liquid from the atomizer head 20. Furthermore, the elliptical structure of the atomizer tube 21 effectively prevents the atomizer head 20 from rotating within the liquid sealing member 13, ensuring precise alignment and communication between the liquid inlet 211 and the liquid flow hole 134.

[0129] In addition, in this embodiment, the structure of the battery assembly is the same as that of the first embodiment and will not be described again here.

[0130] Inspired by the above-described ideal embodiments of the present invention, through the above description, relevant staff can make various changes and modifications without departing from the scope of the present invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
