Description

Technical Field

[0001] The present application belongs to the technical field of electronic cigarettes, and specifically relates to an electronic cigarette cartridge and an electronic cigarette. Background Art

[0002] As a healthy and convenient consumer product, electronic cigarettes have been favored by consumers in recent years and their use has become increasingly popular. Electronic cigarette products use the method of atomizing the e-liquid to provide users with inhalable smoke.

[0003] In the prior art, in order to facilitate users to carry and use electronic cigarettes, electronic cigarette products have a compact and small appearance design. This design method results in a very compact internal structure of the electronic cigarette product.

[0004] However, due to the limited space inside the electronic cigarette products and the very compact structure inside the electronic cigarettes, the internal structure of the electronic cigarette products is prone to some functional defects. For example, the compact structure leads to a smaller atomization bin and liquid storage bin, and a smaller atomization bin easily leads to a small amount of smoke atomization, which in turn leads to incomplete atomization and affects the taste of consumers. A smaller liquid storage bin easily leads to a small e-liquid capacity, which cannot meet the usage needs of demanding consumers. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide an electronic cigarette cartridge and an electronic cigarette, which can solve the problem of small atomization chamber and liquid storage chamber of the electronic cigarette cartridge in the prior art to a certain extent.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0007] In a first aspect, an electronic cigarette cartridge is provided, comprising: a shell, the shell being provided with an airway wall; a cover body, the cover body being fixedly connected to the shell, the cover body and the shell enclosing a accommodating chamber; a bracket, the bracket being arranged in the accommodating chamber, one end of the bracket being fixedly connected to the airway wall, the other end of the bracket being fixedly connected to the cover body, the airway wall and the bracket dividing the accommodating chamber into a smoke channel and a liquid storage chamber, the smoke channel comprising an air extraction section and an atomization section which are interconnected; wherein, the bracket and the cover body enclose the atomization section, and the shell, the bracket and the cover body enclose the liquid storage chamber.

[0008] In an embodiment of the present application, the shell and the cover body are enclosed to form a accommodating chamber, and the shell also has an airway wall. A bracket is also arranged in the accommodating chamber, one end of the bracket is fixedly connected to the airway wall, and the other end of the bracket is fixedly connected to the cover body. The airway wall and the bracket separate the accommodating chamber into a smoke channel and a liquid storage chamber, so that the smoke channel and the liquid storage chamber are independent of each other. The smoke channel is used to provide a flow channel for gas, smoke, and aerosols mixed with gas and smoke, and the liquid storage chamber is used to store tobacco oil. The smoke channel also includes an air extraction section and an atomization section. In actual applications, the tobacco oil in the liquid storage chamber is atomized into smoke in the atomization section. The smoke flows from the atomization section to the air extraction section as the user inhales, and then flows along the air extraction section to the user, and is finally inhaled by the user. Specifically, the atomization section is formed by enclosing the bracket and the cover body, and the liquid storage chamber is formed by enclosing the shell, the bracket, and the cover body. Furthermore, the smoke channel may include an air inlet and an air outlet. During actual use by the user, outside air can enter the smoke channel through the air inlet, and the outside gas and smoke are mixed to form an aerosol, which then flows through the smoke channel to the air outlet and finally flows to the user and is inhaled by the user. There are many parts in the electronic cigarette cartridge in the prior art, resulting in insufficient space in the accommodating chamber, which in turn results in a small space for the area where the smoke oil is atomized and the area where the smoke oil is placed. This may cause incomplete atomization and affect the user experience, and may also be difficult to meet user needs due to the small amount of smoke oil. The electronic cigarette cartridge of the embodiment of the present application can be used by the user only by setting a shell, a bracket, an atomization assembly and a lower cover assembly. Under the condition that the space in the accommodating chamber is the same, the fewer parts set in the accommodating chamber means that the space in the accommodating chamber can be left for the atomization section and the liquid storage chamber. In turn, a larger space can be provided for the storage of smoke oil and the atomization of smoke oil, which has the beneficial effect of improving user experience and better meeting customer needs.

[0009] Optionally, the bracket includes a transition portion, the transition portion is provided with a through hole along the direction of the electronic cigarette cartridge, and the air suction section and the atomization section are connected through the through hole.

[0010] Optionally, the bracket also includes a first cylinder, which is arranged on one side of the transition portion, fixed to the opening of the through hole, connected to the airway wall, and the first cylinder and the airway wall enclose to form the air extraction section.

[0011] Optionally, the bracket also includes a second cylinder, which is arranged on a side of the transition portion away from the first cylinder, the second cylinder is fixed to the opening of the through hole, the second cylinder is connected to the cover body, and the second cylinder and the cover body enclose the atomization section.

[0012] Optionally, the cover body includes an atomizer assembly and a lower cover assembly, the lower cover assembly is connected to the shell, the atomizer assembly is clamped between the bracket and the lower cover assembly along the length direction of the electronic cigarette cartridge, and the atomizer assembly is arranged in the smoke channel.

[0013] Optionally, the lower cover assembly includes a main body and a conductive nail, the main body is provided with an electrode hole and a wiring hole, the electrode hole is connected to the liquid storage chamber, the conductive nail is passed through the electrode hole, and the heating wire of the atomization assembly passes through the wiring hole and is electrically connected to the conductive nail.

[0014] Optionally, the electrode hole includes a coaxial and through first hole and a second hole, the aperture of the first hole is smaller than the aperture of the second hole, and the first hole is arranged at the end of the second hole close to the bracket; the connecting part of the first hole and the second hole has a transition surface perpendicular to the axial direction of the electrode hole.

[0015] Optionally, the conductive nail includes a first conductive part and a second conductive part coaxially connected to each other, the diameter of the first conductive part is smaller than the diameter of the second conductive part, and the first conductive part is arranged at the end of the second conductive part close to the bracket; wherein the first hole cooperates with the first conductive part, and the second hole cooperates with the second conductive part.

[0016] Optionally, there is a preset gap between the surface of the second conductive portion facing the bracket and the transition surface.

[0017] Optionally, the lower cover assembly further includes a sealing member, wherein the sealing member is disposed in the first hole and is sandwiched between the main body and the first conductive portion.

[0018] In a second aspect, an embodiment of the present application further provides an electronic cigarette, comprising the electronic cigarette cartridge as described above.

[0019] In an embodiment of the present application, the electronic cigarette includes the electronic cigarette cartridge described in any of the above embodiments. By arranging a bracket connected to the cover body and the airway wall respectively on the electronic cigarette cartridge, the number of components arranged in the accommodating cavity is as small as possible when the space in the accommodating cavity is the same. The fewer components in the accommodating cavity means that more space can be left for the atomization section and the liquid storage cavity in the accommodating cavity, which can provide more space for the storage and atomization of the e-liquid, thereby improving the user experience and better meeting the beneficial effects of customer needs.

[0026] The electronic cigarette cartridge and the electronic cigarette provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0027] See also Figure 1 to Figure 2The embodiment of the present application provides an electronic cigarette cartridge, comprising: a shell 10, the shell 10 is provided with an airway wall 11; a cover body 20, the cover body 20 and the shell 10 are fixedly connected, and the cover body 20 and the shell 10 are enclosed to form a accommodating chamber 40; a bracket 30, the bracket 30 is arranged in the accommodating chamber 40, one end of the bracket 30 is fixedly connected to the airway wall 11, and the other end of the bracket 30 is fixedly connected to the cover body 20, the airway wall 11 and the bracket 30 separate the accommodating chamber 40 into a smoke channel 41 and a liquid storage chamber 42, and the smoke channel 41 includes an air extraction section 411 and an atomization section 412 that are interconnected; wherein, the bracket 30 and the cover body 20 are enclosed to form the atomization section 412, and the shell 10, the bracket 30 and the cover body 20 are enclosed to form the liquid storage chamber 42.

[0028] In the embodiment of the present application, the housing 10 and the cover 20 enclose a receiving chamber 40, and the housing 10 also has an airway wall 11, and a bracket 30 is also arranged in the receiving chamber 40, one end of the bracket 30 is fixedly connected to the airway wall 11, and the other end of the bracket 30 is fixedly connected to the cover 20, and the airway wall 11 and the bracket 30 separate the receiving chamber 40 into a smoke channel 41 and a liquid storage chamber 42, so that the smoke channel 41 and the liquid storage chamber 42 are independent of each other, and the smoke channel 41 is provided to provide a flow channel for gas, smoke, and aerosol mixed with gas and smoke, and the liquid storage chamber 42 is provided to store tobacco oil. The smoke channel 41 also includes an air extraction section 411 and an atomization section 412. In actual application, the tobacco oil in the liquid storage chamber 42 is atomized into smoke in the atomization section 412, and the smoke flows from the atomization section 412 to the air extraction section 411 as the user inhales, and then flows along the air extraction section 411 to the user, and is finally inhaled by the user. Specifically, the atomization section 412 is formed by the bracket 30 and the cover body 20, and the liquid storage chamber 42 is formed by the shell 10, the bracket 30 and the cover body 20. Furthermore, the smoke channel 41 may include an air inlet and an air outlet. During actual use by the user, the outside air enters the smoke channel 41 through the air inlet, and the outside gas and smoke are mixed to form an aerosol. The aerosol then flows through the smoke channel 41 to the air outlet and finally flows to the user and is inhaled by the user. There are many parts in the electronic cigarette cartridge in the prior art, resulting in insufficient space in the accommodating chamber 40, which in turn results in a smaller space for the area where the smoke oil is atomized and the area where the smoke oil is stored. This may cause incomplete atomization and affect the user experience, and may also be difficult to meet user needs due to the small amount of smoke oil. The electronic cigarette cartridge of the embodiment of the present application can be used by the user only by setting up the shell 10, the bracket 30, the atomization assembly 21 and the lower cover assembly 22. Under the condition that the space in the accommodating chamber 40 is the same, the fewer parts arranged in the accommodating chamber 40 means that more space can be left for the atomization section 412 and the liquid storage chamber 42 in the accommodating chamber 40, which can provide more space for the storage and atomization of the e-liquid, which has the beneficial effect of improving the user experience and better meeting the customer needs.

[0029] Optionally, in the embodiment of the present application, the bracket 30 includes a transition portion 31 , the transition portion 31 is provided with a through hole 311 along the direction of the electronic cigarette cartridge, and the air suction section 411 and the atomization section 412 are connected through the through hole 311 .

[0030] In the embodiment of the present application, the setting of the transition part 31 is used to connect the end of the bracket 30 connected to the airway wall 11 and the end of the bracket 30 connected to the cover body 20. The transition part 31 is provided with a through hole 311 along the direction of the electronic cigarette cartridge, and the setting of the through hole 311 is used to achieve the connection between the suction section 411 and the atomization section 412, thereby realizing the user's inhalation of the aerosol. It can be understood that the airway wall 11 and the cover body 20 are relatively arranged on both sides of the transition part 31. Since the bracket 30 and the cover body 20 enclose the atomization section 412, it can be understood that the process of atomizing the smoke oil to form smoke occurs in the transition part 31, the bracket 30 connected to the cover body 20, and the area enclosed by the cover body 20. When the smoke flows through the through hole 311 with the user's inhalation, it enters the suction section 411, and then mixes with the outside air to form an aerosol and flows to the air outlet. In the embodiment of the present application, by opening a through hole 311 on the transition portion 31, the connection between the atomization section 412 and the exhaust section 411 can be achieved without adding new components in the accommodating chamber 40, which has the beneficial effect of reducing the space occupied in the accommodating chamber 40.

[0031] Optionally, in an embodiment of the present application, the bracket 30 also includes a first cylinder 32, which is arranged on one side of the transition portion 31, and is fixed to the opening of the through hole 311, and is connected to the airway wall 11, and the first cylinder 32 and the airway wall 11 enclose a suction section 411.

[0032] In the embodiment of the present application, the first cylinder 32 is used to connect to the airway wall 11, and the first cylinder 32 is arranged on one side of the transition portion 31. The first cylinder 32 and the airway wall 11 enclose an air extraction section 411. The first cylinder 32 is fixed to the opening of the through hole 311. The air extraction end is connected to the atomization end through the through hole 311. When the user inhales, the smoke flows through the through hole 311, enters the air extraction section 411, and is then inhaled by the user after flowing through the air extraction section 411.

[0033] It should be noted that the first cylinder 32 can be sleeved on the outer periphery of the airway wall 11, and the first cylinder 32 can also be inserted into the airway wall 11. This embodiment does not impose any limitation on the specific connection method between the first cylinder 32 and the airway wall 11, and can achieve the aerosol flowing to the user in the suction section 411.

[0034] Optionally, in an embodiment of the present application, the bracket 30 also includes a second barrel 33, which is arranged on a side of the transition portion 31 away from the first barrel 32, and the second barrel 33 is fixed to the opening of the through hole 311, and the second barrel 33 is connected to the cover body 20, and the second barrel 33 and the cover body 20 enclose to form an atomization section 412.

[0035] In the embodiment of the present application, the second cylinder 33 is used to connect the cover 20, and the second cylinder 33 is arranged on the side of the transition part 31 away from the first cylinder 32. It can be understood that the first cylinder 32 and the second cylinder 33 are arranged opposite to each other, and the second cylinder 33 is fixed to the opening of the through hole 311. It can be understood that the process of atomizing the e-liquid to form smoke occurs in the area enclosed by the transition part 31, the second cylinder 33 and the cover 20, and then the smoke flows through the through hole 311, enters the suction section 411, and then is inhaled by the user after flowing through the suction section 411.

[0036] Optionally, in an embodiment of the present application, the cover body 20 includes an atomizer assembly 21 and a lower cover assembly 22, the lower cover assembly 22 is connected to the shell 10, the atomizer assembly 21 is clamped between the bracket 30 and the lower cover assembly 22 along the length direction of the electronic cigarette cartridge, and the atomizer assembly 21 is arranged in the smoke channel 41.

[0037] In the embodiment of the present application, the atomizer assembly 21 is used to atomize the smoke oil to form smoke to meet the needs of the user. The lower cover assembly 22 is provided to connect and cooperate with the housing 10 to form a accommodating chamber 40 on the one hand, and the lower cover assembly 22 is also provided to provide a limiting effect for the atomizer assembly 21 on the other hand. Specifically, the atomizer assembly 21 is arranged in the smoke channel 41. Further, the atomizer assembly 21 generally includes an oil guide 211 and a heating wire 212. Part of the oil guide 211 is arranged in the atomization section 412, and both ends of the oil guide 211 extend into the liquid storage chamber 42. The heating wire 212 is wound around part of the oil guide 211. Specifically, the oil guide 211 can be a cotton core, a part of the cotton core can be located in the liquid storage chamber 42, and another part of the cotton core can be located in the atomization section 412. By utilizing the adsorption capacity of the cotton core for liquid, the atomizer assembly 21 can transport the liquid in the liquid storage chamber 42 to the atomization section 412 through the cotton core for atomization. For example, the cotton core can be a long strip of liquid-absorbing cotton, which can extend in the left and right directions, and the two ends of the cotton core can extend into the liquid storage chamber 42 from the corresponding notches, and the middle part of the cotton core can be located in the atomization section 412. The liquid in the liquid storage chamber 42 can gradually penetrate the entire cotton core through the end of the cotton core, and the cotton core can absorb the liquid until it reaches a saturated state, thereby realizing the liquid from the liquid storage chamber 42 to the atomization section 412, so as to facilitate the atomization of the liquid. The heating wire 212 can be a heating metal wire, and the heating metal wire heats to atomize the tobacco oil on the cotton core. The bracket 30 and the lower cover assembly 22 clamp the atomization assembly 21 along the direction of the electronic cigarette cartridge to limit the atomization assembly 21 and prevent the adverse effects caused by the displacement of the atomization assembly 21 during use. In the embodiment of the present application, through the cooperation between the bracket 30 and the lower cover assembly 22, the atomization assembly 21 can be fixed without adding new parts in the accommodating chamber 40, which has the beneficial effect of reducing the space occupied in the accommodating chamber 40.

[0038] It should be noted that the end surface of the lower cover assembly 22 close to the atomizer assembly 21 may be provided with a groove, and the groove is used to fix the atomizer assembly 21. A groove is provided on the end surface of the lower cover assembly 22 facing the atomizer assembly 21, and the atomizer assembly 21 is fixed by the groove. The fixing structure is simple and has high stability. The groove can be formed into an arc groove matching the outer surface of the cotton core, and the end of the cotton core can be mounted in the groove, and the positioning and fixing of the cotton core is achieved by the groove.

[0039] Optionally, in an embodiment of the present application, the lower cover assembly 22 includes a main body 221 and a conductive pin 222, the main body 221 is provided with an electrode hole 2211 and a wiring hole 2212, the electrode hole 2211 is connected to the liquid storage chamber 42, the conductive pin 222 is passed through the electrode hole 2211, and the heating wire 212 of the atomization assembly 21 passes through the wiring hole 2212 and is electrically connected to the conductive pin 222.

[0040] In the embodiment of the present application, the main body 221 is used to connect with the housing 10 to form the accommodating chamber 40. The main body 221 is also provided with an electrode hole 2211 and a wiring hole 2212, wherein the electrode hole 2211 is connected with the liquid storage chamber 42, and the conductive nail 222 is penetrated through the electrode hole 2211. The conductive nail 222 is used to connect with the heating wire 212 of the atomizing assembly 21 to make the heating wire 212 generate heat. At the same time, the conductive nail 222 also closes the liquid storage chamber 42, which has the function of preventing the leakage of the smoke oil in the liquid storage chamber 42. The wiring hole 2212 is used to provide a placement space for the heating wire 212 of the atomizing assembly 21. Specifically, the heating wire 212 passes through the wiring hole 2212 and extends into the electrode hole 2211. When the electrode hole 2211 is penetrated into the electrode hole 2211, the heating wire 212 contacts the electrode to make the heating wire 212 generate heat. In addition, passing the heating wire 212 of the atomizer assembly 21 through the wiring hole 2212 has the beneficial effect of limiting and guiding the heating wire 212, thereby preventing the easily deformed heating wire 212 from deforming or becoming detached from the conductive nail 222 and becoming ineffective.

[0041] It should be noted that the lower cover assembly 22 may also include a first sealing ring 224, which is used to achieve sealing between the body 221 and the shell 10, and prevent the smoke oil in the liquid storage chamber 42 from leaking out from the connection between the body 221 and the shell 10. Specifically, the first sealing ring 224 is sleeved on the periphery of the body 221, the body 221 includes an outer wall facing the shell 10, and the shell 10 includes an inner wall facing the body 221. It can be understood that in practical applications, the outer wall and the inner wall are fitted to form a matching surface between the shell 10 and the body 221. Further, the first sealing ring 224 is sandwiched between the outer wall and the inner wall, and the first sealing ring 224 is sleeved on the outer periphery of the body 221. The first sealing ring 224 can be deformed. When the outer wall and the inner wall are relatively squeezed at the same time, the first sealing ring 224 is deformed to achieve sealing between the outer wall and the inner wall, which has the beneficial effect of preventing the smoke oil from leaking out of the liquid storage chamber 42 along the gap between the outer wall and the inner wall.

[0042] Optionally, in an embodiment of the present application, the electrode hole 2211 includes a coaxial and through first hole 2211a and a second hole 2211b, the aperture of the first hole 2211a is smaller than the aperture of the second hole 2211b, and the first hole 2211a is arranged at the end of the second hole 2211b close to the bracket 30; the connecting part between the first hole 2211a and the second hole 2211b has a transition surface 2211c perpendicular to the axial direction of the electrode hole 2211.

[0043] In the embodiment of the present application, the electrode hole 2211 includes a coaxial and through first hole 2211a and a second hole 2211b. It can be understood that the electrode hole 2211 is a stepped hole arranged along the direction of the electronic cigarette cartridge, and the aperture of the first hole 2211a close to the end of the bracket 30 is smaller than the aperture of the second hole 2211b. In the actual assembly process, the end of the conductive nail 222 is first inserted from the second hole 2211b and then continues to be inserted into the first hole 2211a. The end of the conductive nail 222 cooperates with the first hole 2211a, and the tail of the conductive nail 222 cooperates with the second hole 2211b. It can be understood that in order to cooperate with the stepped hole, the conductive nail 222 is also a stepped structure. In addition, the electrode hole 2211 is a stepped hole, and the aperture of the first hole 2211a is different from the aperture of the second hole 2211b. Therefore, the connecting portion of the first hole 2211a and the second hole 2211b has a transition surface 2211c perpendicular to the axial direction of the electrode hole 2211.

[0044] Furthermore, during the assembly process, the oil guide 211 is first assembled to the lower cover assembly 22, the heating wire 212 passes through the wiring hole 2212 and is bent to the position of the conductive nail 222, and contacts the conductive nail 222, and then the bracket 30 is assembled to the lower cover assembly 22. The bracket 30 and the lower cover assembly 22 are interference fit, which can prevent oil leakage. In the next step, the smoke oil is injected into the liquid storage chamber 42 from the electrode hole 2211, and the conductive nail 222 is installed after the smoke oil is injected to achieve the closure of the liquid storage chamber 42. Since the oil injection process is carried out after the lower cover assembly 22 is assembled, the oil injection amount is greatly improved compared with the process of first injecting oil and then installing the lower cover assembly 22, and the air bubble space in the oil storage chamber is small, and the risk of oil leakage is greatly reduced. Since there are fewer parts in the accommodating chamber 40, the atomization section 412 is also much larger, and the atomized smoke oil can be fully combined with the outside air to form an aerosol, which can bring a better experience to the user. In addition, the conductive nail 222 and the heating wire 212 are directly assembled on the main body 221. The main body 221 directly positions the oil guide 211 and the conductive nail 222. The assembly dimension chain is shortened a lot, and the contact between the heating wire 212 and the conductive nail 222 is guaranteed, which can better solve the problem of poor contact.

[0045] Optionally, in an embodiment of the present application, the conductive nail 222 includes a first conductive part 2221 and a second conductive part 2222 coaxially connected to each other, the diameter of the first conductive part 2221 is smaller than the diameter of the second conductive part 2222, and the first conductive part 2221 is arranged at the end of the second conductive part 2222 close to the bracket 30; wherein the first hole 2211a cooperates with the first conductive part 2221, and the second hole 2211b cooperates with the second conductive part 2222.

[0046] In the embodiment of the present application, the first conductive part 2221 is configured to cooperate with the first hole 2211a, and the second conductive part 2222 is configured to cooperate with the second hole 2211b, and the diameter of the first conductive part 2221 is smaller than the diameter of the second conductive part 2222. Since the electrode hole 2211 and the liquid storage chamber 42 are connected, the conductive nail 222 is also configured to seal the liquid storage chamber 42 without adding new parts to the accommodating chamber 40 to prevent the smoke oil in the liquid storage chamber 42 from leaking out. In the embodiment of the present application, the first conductive part 2221 that cooperates with the first hole 2211a and the second conductive part 2222 that cooperates with the second hole 2211b can achieve the beneficial effect of preventing the smoke oil from leaking out of the liquid storage chamber 42 without adding new parts to the accommodating chamber 40.

[0047] Further, the conductive nail 222 may also include a second sealing ring 2223, and the second sealing ring 2223 is provided to enhance the sealing performance of the second conductive part 2222 and the body 221. Specifically, the second sealing ring 2223 is sleeved on the periphery of the second conductive part 2222, and the second sealing ring 2223 is sandwiched between the second conductive part 2222 and the second hole 2211b. The second sealing ring 2223 has the function of blocking the matching gap between the second sealing ring 2223 and the second hole 2211b. Further, the second sealing ring 2223 may be deformed, and in the case of interference fit between the second conductive part 2222 and the second hole 2211b, the second sealing ring 2223 sandwiched between the second conductive part 2222 and the second hole 2211b is deformed to achieve sealing of the matching gap between the second sealing ring 2223 and the second hole 2211b. In the event that the seal 223 fails, the smoke oil may enter the electrode hole 2211 from the liquid storage chamber 42. The provision of the second sealing ring 2223 can prevent the smoke oil from leaking out of the electrode hole 2211 to the outside of the electronic cigarette cartridge.

[0048] Optionally, in the embodiment of the present application, there is a preset gap between the surface of the second conductive portion 2222 facing the bracket 30 and the transition surface 2211 c.

[0049] In the embodiment of the present application, the preset gap is set to provide a placement space for the heating wire 212. In actual applications, due to the low precision of the processing technology, the length of the heating wire 212 cannot be accurately within the actually required length range. Usually, after the heating wire 212 contacts the conductive nail 222, there is still a long section of the heating wire 212 that is not used. The unused heating wire 212 can be set in the preset gap, and the heating wire 212 does not need to be further shortened for a second time, which has the beneficial effect of improving production efficiency and being beneficial to the heating wire 212.

[0050] Optionally, in the embodiment of the present application, the lower cover assembly 22 further includes a sealing member 223 , which is disposed in the first hole 2211 a and is sandwiched between the body 221 and the first conductive portion 2221 .

[0051] In the embodiment of the present application, the seal 223 is provided to prevent the smoke oil from leaking out from the matching gap between the conductive pin 222 and the electrode hole 2211. Specifically, the seal 223 is provided in the first hole 2211a and is sandwiched between the body 221 and the first conductive part 2221. The seal 223 isolates the conductive pin 222 and the smoke oil in the liquid storage chamber 42, preventing the smoke oil from leaking out of the liquid storage chamber 42, and has the beneficial effect of improving the sealing performance of the lower cover assembly 22.

[0052] Optionally, in an embodiment of the present application, an electronic cigarette includes the electronic cigarette cartridge as described above.

[0053] In an embodiment of the present application, the electronic cigarette includes the electronic cigarette cartridge described in any of the above embodiments. By arranging a bracket 30 connected to the cover body 20 and the airway wall 11 respectively on the electronic cigarette cartridge, when the space in the accommodating chamber 40 is the same, as few components as possible are arranged in the accommodating chamber 40. The fewer components in the accommodating chamber 40 means that more space can be left for the atomization section 412 and the liquid storage chamber 42 in the accommodating chamber 40, which can provide more space for the storage and atomization of the e-liquid, which has the beneficial effect of improving the user experience and better meeting customer needs.

[0054] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
