Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a cigarette cartridge and an electronic cigarette. Background Art

[0002] As people pay more and more attention to health, they realize that traditional cigarettes are harmful to health. Therefore, a product called "electronic cigarettes" has emerged. Compared with traditional cigarettes, electronic cigarettes can meet the physiological needs of users while avoiding harmful substances such as tar and carbon monoxide brought by traditional cigarettes.

[0003] Electronic cigarettes convert liquid into smoke through the atomizer core, allowing users to get the smoking experience. There are two types of electronic cigarette liquid filling methods: oil storage cotton and oil storage cavity. The oil storage cotton form is more wasteful and has low production efficiency. As for the oil storage cavity structure, many electronic cigarettes on the market that use the oil storage cavity type have oil leakage problems, and some electronic cigarettes that use anti-leakage structures do not have pressure-resistant structures. Even some electronic cigarettes with pressure-resistant and anti-leakage structures only replace the oil cavity, and the atomization part and the smoke cartridge are separated. When replacing the smoke cartridge, the smoke liquid in the newly replaced smoke cartridge will mix with the residual smoke liquid in the atomization part, resulting in the problem of cross-flavor, which seriously affects the user's smoking experience.

[0033] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Although the description of the present invention will be introduced in conjunction with preferred embodiments, this does not mean that the features of this invention are limited to this implementation manner. On the contrary, the purpose of introducing the invention in conjunction with the implementation manner is to cover other alternatives or modifications that may be extended based on the claims of the present invention. To provide a deep understanding of the present invention, many specific details will be included in the following description. The present invention can also be implemented without using these details. In addition, to avoid confusing or obscuring the key points of the present invention, some specific details will be omitted in the description.

[0034] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0035] See Figures 1-4 As shown, in one embodiment, the present invention provides a cartridge, including: a liquid storage part 11 for storing e-liquid, and the liquid storage part 11 is provided with a main liquid outlet 111; an atomization part 12 for atomizing the e-liquid; a control valve 13 for controlling the opening and closing of the main liquid outlet 111; wherein, in the first state, the control valve 13 opens the main liquid outlet 111, and the e-liquid in the liquid storage part 11 can flow from the main liquid outlet 111 through the control valve 13 into the atomization part 12; in the second state, the control valve 13 closes the main liquid outlet 111 to prevent the e-liquid from flowing out of the liquid storage part 11.

[0036] That is to say, the cartridge mainly consists of a liquid storage part 11, an atomization part 12 and a control valve 13. Among them, the liquid storage part 11 and the atomization part 12 are connected through the control valve 13. The control valve 13 can control the opening and closing of the main liquid outlet 111 to prevent the e-liquid from leaking from the liquid storage part 11 when not in use. By arranging the liquid storage part 11 and the atomization part 12 together in the cartridge 1, it is convenient for encapsulation. When replacing the cartridge 1, the liquid storage part 11 and the atomization part 12 can be replaced together, which can effectively solve the problem of flavor mixing caused by the remaining e-liquid in the atomization part 12.

[0037] Meanwhile, in the first state, the control valve 13 opens the main liquid outlet 111, and the e-liquid in the liquid storage part 11 can flow from the main liquid outlet 111 through the control valve 13 into the atomization part 12. At this time, the e-liquid flowing into the atomization part 12 can be atomized by the atomization part 12 to form an aerosol, which can be inhaled by the user. In the second state, the control valve 13 closes the main liquid outlet 111 to prevent the e-liquid from flowing out of the liquid storage part 11, ensuring that the e-liquid is stored in the liquid storage part 11 and avoiding the situation of e-liquid leakage.

[0038] Adopting the above technical solution, arranging the liquid storage part and the atomization part together in the cartridge is convenient for encapsulation. When replacing, the whole cartridge can be replaced, which can effectively solve the problem of flavor mixing. At the same time, the atomization part and the liquid storage part are connected through a control valve. By operating the opening and closing of the control valve to realize the opening and closing of the main liquid outlet, the problem of e-liquid leakage can be effectively solved.

[0039] It should be noted that the specific structure of the control valve in this embodiment is not limited and can be reasonably set according to actual needs as long as it can realize the opening and closing of the main liquid outlet and ensure that the e-liquid will not leak in the non-use state.

[0040] Specifically, as shown in Figures 1-4 In an embodiment, the control valve 13 includes: a valve body 130, one end of the valve body 130 extends into the main liquid outlet 111, and the other end is connected to the atomization part 12; a valve seat 131, arranged on the atomization part 12 and connected to the valve body 130 for the installation of the valve body 130. Among them, a liquid guiding hole 133 is provided in the valve body 130, and the liquid inlet 134 of the liquid guiding hole 133 is located in the main liquid outlet 111. In the first state, the liquid inlet 134 can guide the e-liquid in the liquid storage part 11 into the liquid guiding hole 133, and the liquid outlet 135 of the liquid guiding hole 133 is communicated with the atomization part 12, which can guide the e-liquid entering the liquid guiding hole 133 into the atomization part 12.

[0041] That is to say, the control valve 13 is mainly composed of a valve body 130 and a valve seat 131. Among them, the end of the valve body 130 extending into the main liquid outlet 111 can seal the main liquid outlet 111 to ensure that the e-liquid does not leak from the main liquid outlet 111 in the non-use state. The valve seat 131 is arranged on the atomization part 12. The other end of the valve body 130 is connected to the valve seat 131 and can extend into the atomization part 12 and be connected to the atomization part 12, so that the e-liquid entering the valve body 130 can smoothly flow into the atomization part 12. Among them, the valve body 130 and the valve seat 131 are detachably connected, which is convenient for the assembly and disassembly of the two and is also conducive to the replacement of components. Preferably, the valve body 130 and the valve seat 131 are detachably connected by threads. In other embodiments, the valve body 130 and the valve seat 131 can also be detachably connected by other connection methods, such as snap connection, riveting and other connection methods. In addition, the valve body and the valve seat can also be fixedly connected, such as being processed by welding, integral molding, etc.

[0042] Further, referring to Figures 1-4 As shown, a liquid guiding hole 133 is provided in the valve body 130. The liquid inlet 134 of the liquid guiding hole 133 is located in the main liquid outlet 111. In the first state, the liquid inlet 134 can introduce the e-liquid in the liquid storage part 11 into the liquid guiding hole 133. The liquid outlet 135 of the liquid guiding hole 133 is communicated with the atomization part 12 and can introduce the e-liquid entering the liquid guiding hole 133 into the atomization part 12.

[0043] That is, in the first state, that is, the state when the user is using, the e-liquid in the liquid storage part 11 flows out from the main liquid outlet 111 and then enters the liquid guiding hole 133 through the liquid inlet 134. The e-liquid entering the liquid guiding hole 133 flows into the atomization part 12 from the liquid outlet 135 of the liquid guiding hole 133 (as shown by the solid line arrow in Figure 1 ), and then is atomized by the atomization part 12 to form an aerosol and is sucked by the user (as shown by the dotted line arrow in Figure 1 ). By providing a liquid guiding hole on the valve body, it can be ensured that the e-liquid can continuously and reliably flow into the atomization part in the first state, there will be no e-liquid leakage, and the atomization part can also be prevented from dry burning, ensuring the use safety.

[0044] Further, in order to better ensure that the e-liquid does not leak from the main liquid outlet 111, referring to Figures 1-4 As shown, in this embodiment, a sealing ring 137 is provided on the valve body 130. The sealing ring 137 is located downstream of the liquid inlet 134 and is used to keep the valve body 130 and the main liquid outlet 111 sealed. That is to say, in the first state, the second state, and the process of switching between the two states, the sealing ring 137 always fits with the inner wall of the main liquid outlet 111, and can well achieve the sealing effect and avoid the occurrence of e-liquid leakage.

[0045] Referring to Figures 1-4As shown, in one embodiment, the end face of the valve body 130 located within the main liquid outlet 111 is a conical boss 132. The main liquid outlet 111 is provided with a funnel portion. In the second state, the conical boss 132 can be fitted and sealed with the funnel portion. That is, by setting the end face of the valve body 130 located within the main liquid outlet 111 as the conical boss 132 and setting the main liquid outlet 111 as the funnel portion, when in the second state, the two can better achieve the sealing effect through the tight fit of the conical surface to ensure that there is no leakage of e-liquid.

[0046] In addition, to ensure that the conical boss 132 can effectively and reliably close the main liquid outlet 111 in the second state, refer to Figure 1 and Figure 3 As shown, in this embodiment, a sealing ring 136 is provided on the conical boss 132 to seal the valve body 130 and the liquid outlet 111 of the liquid storage portion 11 in the second state. That is, in the second state, a sealing ring 136 is provided between the conical boss 132 and the funnel portion. The sealing ring 136 can effectively seal the gap between the conical boss 132 and the funnel portion, better achieving the sealing effect and ensuring that there is no leakage of e-liquid.

[0047] Furthermore, refer to Figures 1-4 As shown, in one embodiment, the atomizing portion 12 includes: an atomizing assembly 121; an atomizing portion mounting bracket 120 for mounting the atomizing assembly 121; wherein, a first reset member 14 is provided between the atomizing portion mounting bracket 120 and the liquid storage portion 11, and the first reset member 14 can reset the control valve 13 from the first state to the second state.

[0048] That is, the atomizing portion 12 is mainly composed of the atomizing assembly 121 and the atomizing portion mounting bracket 120. Optionally, the atomizing assembly 121 includes a buffer cotton 122, a heating element 124, an electrode 125, and a heating element mounting seat 123. The buffer cotton 122, the heating element 124, and the electrode 125 are all installed within the heating element mounting seat 123. The heating element 124 is used for atomizing e-liquid. The electrode 125 is connected to the heating element 124 and can connect the heating element 124 and the circuit within the cigarette rod 2 after the cigarette cartridge 1 and the cigarette rod 2 are assembled. The buffer cotton 122 is disposed upstream of the heating element 124 and is in close contact with the heating element 124, and is used for sucking the e-liquid within the valve body 130 into the atomizing assembly 121. The atomizing assembly 121 is installed on the atomizing portion mounting bracket 120. The valve seat 131 of the control valve 13 is also fixedly installed on the atomizing portion mounting bracket 120. The atomizing portion 12 can move relative to the liquid storage portion 11 together with the control valve 13. Among them, the liquid storage portion 11 is fixedly connected to the housing 10 of the cigarette cartridge 1, and by operating the housing 10 of the cigarette cartridge 1, the atomizing portion 12 can move relative to the liquid storage portion 11 together with the control valve 13.

[0049] Specifically, in order to close the main liquid outlet 111 of the liquid storage part by the control valve 13 in the non-edible state, refer to Figures 1-4 As shown, in this embodiment, a first reset member 14 is provided between the atomization part mounting bracket 120 and the liquid storage part 11. The first reset member 14 can reset the control valve 13 from the first state to the second state. That is to say, the first reset member 14 can keep the control valve 13 in a state of closing the main liquid outlet 111 of the liquid storage part 11 in the second state, ensuring that the control valve 13 can seal the main liquid outlet 111 in the second state.

[0050] It should be noted that the present invention does not limit the specific structure of the first reset member, and can be reasonably selected and set according to actual needs, as long as it is ensured that the control valve can seal the main liquid outlet in the non-edible state. Specifically, refer to Figures 1-4 As shown, in this embodiment, the first reset member 14 is a spring, one end of which abuts against the lower end of the liquid storage part 11, and the other end abuts against the upper end of the atomization part mounting bracket 120.

[0051] In the first state, the first reset member 14 makes the atomization part 12 and the control valve 13 move away from the liquid storage part 11 by virtue of its own elastic restoring force, so that the upper end of the valve body of the control valve 13 contacts the main liquid outlet 111 of the liquid storage part 11, realizing the sealing of the main liquid outlet 111 and making the control valve 13 reset from the first state to the second state.

[0052] In the second state, pushing the housing 10 of the cartridge 1 makes the atomization part 12 and the control valve 13 move together towards the direction close to the liquid storage part 11, so that the upper end of the valve body of the control valve 13 is separated from the main liquid outlet 111 of the liquid storage part 11, realizing the opening of the main liquid outlet 111 and making the control valve 13 reset from the second state to the first state.

[0053] In other embodiments, the first reset member can also be other structures, such as a pair of same-sex magnetic members respectively arranged on the atomization part and the liquid storage part. Through the mutual repulsion force between the two, the reset of the control valve can be realized. The present invention does not limit this, and can be reasonably selected and set according to actual needs, as long as it is ensured that the first reset member can reset the control valve and seal the main liquid outlet.

[0054] Further, refer to Figures 1-4 As shown, in one embodiment, along the first direction on the valve seat 131 ( Figure 1In the X direction shown in the figure, a guiding groove 1310 is provided for guiding the valve seat 131 to move. Wherein, the first direction is the axial extension direction of the cartridge 1, that is, the control valve 13 and the atomizing part 12 can move relative to the liquid storage part 11 together in the first direction. A guiding groove 1310 is provided on the valve seat 131, and a guiding part capable of cooperating with the guiding groove 1310 is provided at the lower end of the liquid storage part 11. Through the cooperation of the two, the control valve 13 and the atomizing part 12 can move relative to the liquid storage part 11 together in the first direction without circumferential rotation, ensuring the stable and reliable use of the cartridge 1. Along the circumferential direction of the cartridge 1, two guiding grooves 1310 are provided on the valve seat 131, and the two guiding grooves 1310 are symmetrically distributed at 180° around the center. In other embodiments, the valve seat may be provided with other numbers of guiding grooves, and the present invention does not limit this.

[0055] In addition, for the convenience of assembling the valve seat and the atomizing part mounting bracket, refer to Figure 4 As shown in the figure, in one embodiment, a mounting groove 1311 is provided on the valve seat 131, and a protrusion 126 is provided on the atomizing part mounting bracket 120. During installation, the mounting groove 1311 on the valve seat 131 is engaged with the protrusion 126 on the atomizing part mounting bracket 120, which is convenient for the assembly between the two. Along the circumferential direction of the cartridge 1, two mounting grooves 1311 are provided on the valve seat 131, and two protrusions 126 are provided on the atomizing part mounting bracket 120. The two mounting grooves 1311 and the two protrusions 126 are symmetrically distributed at 180° around the center. In other embodiments, the numbers of the mounting groove and the protrusion may also be other numbers, and the present invention does not limit this.

[0056] Furthermore, refer to Figures 1-4 As shown in the figure, in one embodiment, a pressure balance assembly 15 is provided at one end of the liquid storage part 11 away from the main liquid outlet 111. The pressure balance assembly 15 includes a pressure balance chamber 150 and a sealing sphere 151. A gas exchange membrane 152 is provided between the pressure balance chamber 150 and the liquid storage chamber 110 of the liquid storage part 11. The sealing sphere 151 is arranged in the pressure balance chamber 150 for sealing the air outlet 153 of the pressure balance chamber 150 when the gas exchange membrane 152 leaks. By providing the pressure balance assembly 15 on the liquid storage part 11, the pressure in the liquid storage chamber 110 of the liquid storage part 11 can be kept balanced, avoiding the leakage of the liquid storage part 11 when negative pressure occurs.

[0057] Refer to Figures 5-7 As shown in the figure, the present invention also provides an electronic cigarette 00, including: the cartridge 1 in any one of the above embodiments; a cigarette rod 2, provided with an outer shell 20 and an inner shell 21. Wherein, the inner shell 21 is provided with a mounting part 22. The shell of the cartridge 1 extends into the outer shell 20 and is connected to the inner shell 21 through the mounting part 22. In the extending direction of the cigarette rod 2 (such as Figures 5-6In the X direction shown in the figure, the housing 10 of the cartridge 1 can move relative to the cigarette rod 2 and can drive the liquid storage part 11 to move, so that the control valve 13 switches between the first state and the second state.

[0058] That is to say, the electronic cigarette mainly consists of a cartridge 1 and a cigarette rod 2. Among them, the cigarette rod 2 is provided with an outer shell 20 and an inner shell 21. The inner shell 21 is arranged inside the outer shell 20 and is used for installing components such as a battery 25 and a circuit. In order to facilitate the installation of the cartridge 1, an installation part 22 is provided on the inner shell 21, and the part of the cartridge 1 extending into the outer shell 20 can be connected to the inner shell 21 through the installation part 22.

[0059] Specifically, as shown in Figures 5-6 In an embodiment, the atomizing part 12 of the cartridge 1 is fixedly installed on the installation part 22 and is electrically connected to the electrode 221 on the installation part 22. That is to say, the atomizing part 12 is fixedly connected to the installation part 22, and the electrode 125 on the atomizing part 12 is in contact electrical connection with the electrode 221 extending into the installation part 22 in the cigarette rod 2. The electrode 221 contact is installed on the PCB board to realize the electrical connection between the atomizing part 12 and the PCB board.

[0060] Further, in the extending direction of the cigarette rod 2 (such as Figures 5-6 the X direction shown in the figure), the housing 10 of the cartridge 1 can move relative to the cigarette rod 2 and can drive the liquid storage part 11 to move, so that the control valve 13 switches between the first state and the second state. That is to say, in the extending direction of the cigarette rod 2, there is a gap between the housing 10 of the cartridge 1 and the outer shell 20. Push the housing 10 of the cartridge 1 along the extending direction so that the cartridge 1 moves towards the direction close to the installation part 22. Since the atomizing part 12 of the cartridge 1 is fixedly installed on the installation part 22, during the movement, the first resetting part 14 between the liquid storage part 11 and the atomizing part 12 will be compressed. At the same time, the upper part of the valve body 130 of the control valve 13 will also be separated from the main liquid outlet 111 of the liquid storage part 11, realizing the opening of the main liquid outlet 111, so that the control valve 13 switches from the second state to the first state.

[0061] After releasing the cartridge 1, the first resetting part 14 between the liquid storage part 11 and the atomizing part 12 makes the cartridge 1 move in the direction away from the installation part 22 through its own restoring force. That is to say, it makes the liquid storage part 11 move in the direction away from the atomizing part 12. The upper part of the valve body 130 of the control valve 13 will also fit with the main liquid outlet 111 of the liquid storage part 11, realizing the closing of the main liquid outlet 111, so that the control valve 13 switches from the first state to the second state.

[0062] With the above technical solution, by arranging the liquid storage part and the atomization part together in the cartridge, it is convenient for encapsulation. When replacing, the entire cartridge can be replaced, effectively solving the problem of flavor mixing. At the same time, the atomization part and the liquid storage part are connected through a control valve. By operating the opening and closing of the control valve, the opening and closing of the main liquid outlet can be realized, effectively solving the problem of e-liquid leakage. In addition, by pushing the housing of the cartridge, the opening and closing of the main liquid outlet can be achieved, with simple operation and convenient use.

[0063] It should be noted that the specific structure of the installation part in this embodiment is not limited and can be reasonably set according to actual needs.

[0064] Specifically, as shown in Figures 5-6 In one embodiment, the installation part 22 includes: a support plate 23, one end of which is connected to the housing 10 of the cartridge 1 and the other end is connected to the inner housing 21; a second reset member 24 provided between the support plate 23 and the inner housing 21.

[0065] That is to say, the support plate 23 is installed on the inner housing 21, can support the cartridge 1, and is connected to the housing 10 of the cartridge 1. The second reset member 24 is arranged between the support plate 23 and the inner housing 21 and can bear the pressure borne by the support plate 23. When pushing the housing 10 of the cartridge 1 along the extension direction of the cigarette rod 2, the housing 10 of the cartridge 1 can compress the second reset member 24 through the support plate 23, that is, in the first state, the second reset member 24 is in a compressed state.

[0066] After releasing the cartridge 1, the second reset member 24 located between the support plate 23 and the inner housing 21 pushes the cartridge 1 and the support plate 23 to move away from the inner housing 21 through its own restoring force, so that the control valve 13 switches from the first state to the second state. By setting the second reset member 24 and the support plate 23, it can be ensured that after releasing the cartridge 1, the cartridge 1 can reliably move away from the inner housing 21, so that the control valve 13 switches from the first state to the second state, ensuring that the valve body 130 of the control valve 13 closes the main liquid outlet 111 of the liquid storage part 11 and avoiding liquid leakage.

[0067] Furthermore, as shown in Figures 5-6 In this embodiment, a magnetic member 231 is provided on the support plate 23, and a metal sheet is provided at the bottom of the cartridge 1. The support plate 23 and the cartridge 1 are connected by the magnetic attraction of the magnetic member 231 and the metal sheet. Through the magnetic attraction connection, the structure is simple, facilitating the disassembly and replacement of the cartridge 1.

[0068] It should be noted that the specific structure of the second reset member in this embodiment is not limited and can be reasonably selected and set according to actual needs, as long as it can ensure that the control valve is reset to the second state when the cartridge is released.

[0069] Specifically, in one embodiment, the second reset member may include a first magnetic member and a second magnetic member. Among them, the first magnetic member is disposed on the tray, and the second magnetic member is disposed on the inner shell. Through the mutual repulsion force between the two, the reset of the control valve can be achieved. In other embodiments, the second reset member may also be other structures.

[0070] Specifically, refer to Figures 5-6 As shown, in one embodiment, the second reset member 24 includes an elastic member. Preferably, the second reset member 24 is a spring, one end of which abuts against the bottom of the tray 23, and the other end abuts against the upper end of the inner shell 21. At the same time, the inner shell 21 is provided with a mounting protrusion, and the mounting protrusion is provided with a mounting hole 220; a guiding column 230 is provided on the tray 23, and the guiding column 230 extends into the mounting hole 220, which can guide the movement of the tray 23 along the extending direction of the cigarette rod 2, and the elastic member is disposed on the guiding column 230. By providing the guiding column 230 and using the spring as the second reset member 24, not only is the structure simple, easy to use, and convenient for disassembly and assembly, but also through the guiding of the tray 23 by the guiding column 230, the movement of the tray 23 can be made stable, and there will be no jamming problem, ensuring that the electronic cigarette 00 can be used stably and reliably.

[0071] Further, refer to Figures 5-6 As shown, in one embodiment, in the extending direction of the cigarette rod 2, a gap W is provided between the housing 10 of the cigarette cartridge 1 and the outer housing 20 for the movement of the housing 10 of the cigarette cartridge 1, and the movement stroke of the tray 23 is less than or equal to the movement stroke of the cigarette cartridge 1. That is, in the extending direction of the cigarette rod 2, the gap between the housing 10 of the cigarette cartridge 1 and the outer housing 20 is the movement stroke of the cigarette cartridge 1, wherein the movement stroke of the tray 23 is less than or equal to the movement stroke of the cigarette cartridge 1. Specifically, during the opening process of the main liquid outlet 111, the atomizing part 12 and the valve body 130 do not move, and the liquid storage cavity 11 and the outer housing 10 of the cigarette cartridge 1 move together, and the tray 23 moves synchronously in linkage. The synchronous displacement stroke of the two is not less than 1 mm and does not exceed 6 mm. Preferably, 2.5 mm - 3 mm is the best. Within this displacement stroke, it can be ensured that the main liquid outlet 111 can be reliably switched between the closed and open states.

[0072] To avoid the phenomenon of dry burning and ensure the safe use of the electronic cigarette, refer to Figure 7 and in combination with Figures 5-6As shown in the figure, a sliding button 26 is provided on the outer shell 20 of an embodiment. One end of the sliding button 26 is connected to the housing 10 of the cartridge 1, and can drive the housing 10 of the cartridge 1 to move, so that the control valve 13 switches between the first state and the second state; the sliding button 26 is electrically connected to the control circuit 27 in the cigarette rod 2. When the sliding button 26 makes the control valve 13 enter the first state, the sliding button 26 drives the control circuit 27 to supply power to the atomizing part 12, so that the atomizing part 12 atomizes the cigarette liquid entering the atomizing component 121 through the control valve 13. When the sliding button 26 makes the control valve 13 enter the second state, the sliding button 26 drives the control circuit 27 to cut off the power supply to the atomizing part 12, so that the atomizing part 12 stops working.

[0073] That is to say, a sliding button 26 is provided on the outer shell 20, and the interlocking control of the control valve 13 and the atomizing part 12 is realized through the sliding button 26. In the first state, the control valve 13 opens the main liquid outlet 111 of the liquid storage part 11, and the cigarette liquid can flow into the atomizing part 12. At this time, the sliding button 26 can drive the control circuit 27 to supply power to the atomizing part 12, so that the atomizing part 12 atomizes the cigarette liquid entering the atomizing component 121 through the control valve 13. In the second state, the control valve 13 closes the main liquid outlet 111 of the liquid storage part 11, and the cigarette liquid cannot flow into the atomizing part 12. At this time, the sliding button 26 can drive the control circuit 27 to cut off the power supply to the atomizing part 12, so that the atomizing part 12 stops working, avoiding the phenomenon of dry burning and ensuring the use safety of the electronic cigarette 00.

[0074] Generally speaking, by adopting the technical solution of the present application, by arranging the liquid storage part and the atomizing part together in the cartridge, it is convenient for packaging. When replacing, the cartridge can be replaced as a whole, which can effectively solve the problem of flavor mixing. At the same time, the atomizing part and the liquid storage part are connected by a control valve, and the opening and closing of the main liquid outlet are realized by operating the opening and closing of the control valve, which can effectively solve the problem of cigarette liquid leakage. In addition, by pushing the housing of the cartridge, the opening and closing of the main liquid outlet can be realized, and the operation is simple and the use is convenient.
