Electronic cigarette cartridges and electronic cigarettes

[0001] This application claims priority to the Chinese patent application filed on December 21, 2023, with application number 202323510342.1, entitled “Electronic Cigarette Cartridges and Electronic Cigarettes”, and claims priority to the Chinese patent application filed on December 21, 2023, with application number 202323509923.3, entitled “Electronic Cigarette Cartridges and Electronic Cigarettes”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] 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

[0003] As a healthy and convenient consumer product, e-cigarettes have gained popularity in recent years and are becoming increasingly popular. E-cigarettes atomize e-liquid to provide users with inhalable vapor.

[0004] 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 makes the internal structure of the electronic cigarette product very compact.

[0005] However, due to the limited space and compact structure within e-cigarettes, they are prone to functional defects. For example, the compact structure results in smaller atomizer and liquid storage compartments. A smaller atomizer compartment can lead to a smaller amount of smoke atomized, which in turn results in incomplete atomization and affects the consumer's taste. A smaller liquid storage compartment can also result in a smaller e-liquid capacity, which cannot meet the needs of demanding consumers. Summary of the Invention

[0048] The electronic cigarette cartridge and the electronic cigarette provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0049] First embodiment

[0050] 1 to 2 , the first embodiment of the present application provides an electronic cigarette cartridge 1, which includes a shell 10, a cover 20 and a bracket 30. The shell 10 is provided with an airway wall 11; the cover 20 and the shell 10 are fixedly connected, and the cover 20 and the shell 10 enclose a accommodating chamber 40. The bracket 30 is arranged in the accommodating chamber 40, one end of the bracket 30 is directly connected to the airway wall 11, and the other end of the bracket 30 is fixedly connected to the cover 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. The bracket 30 and the cover 20 enclose the atomization section 412, and the shell 10, the bracket 30 and the cover 20 enclose the liquid storage chamber 42.

[0051] According to this embodiment, the smoke channel 41 and the liquid storage chamber 42 are independent of each other. The smoke channel 41 is used to provide a flow channel for gas, smoke, and aerosols mixed with gas and smoke, while the liquid storage chamber 42 is used to store tobacco oil. The smoke channel 41 also includes an air extraction section 411 and an atomization section 412. In actual use, the tobacco oil in the liquid storage chamber 42 is atomized into smoke in the atomization section 412. As the user inhales, the smoke flows from the atomization section 412 to the smoke extraction section 411, and then flows along the smoke extraction section 411 to the user, and is ultimately inhaled by the user. Specifically, the atomization section 412 is formed by the bracket 30 and the cover 20, and the liquid storage chamber 42 is formed by the housing 10, the bracket 30, and the cover 20.

[0052] Furthermore, the smoke channel 41 may include an air inlet and an air outlet. During actual use by the user, outside air can enter 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.

[0053] The electronic cigarette cartridges in the prior art contain many components, resulting in insufficient space in the accommodating chamber 40. This, in turn, results in less space for the area where the smoke oil is atomized and the area where the smoke oil is stored. This may result in incomplete atomization and affect the user experience, or it may be difficult to meet user needs due to the small amount of smoke oil. However, the electronic cigarette cartridge 1 of this embodiment can be used by the user by only providing the housing 10, the bracket 30, the atomization assembly 50 and the lower cover assembly 22. When the space in the accommodating chamber 40 remains the same, the fewer components provided in the accommodating chamber 40, the more space can be left for the atomization section 412 and the liquid storage chamber 42 in the accommodating chamber 40, thereby providing more space for smoke oil storage and atomization. As a result, the user experience is improved and customer needs are better met.

[0054] Specifically, the airway wall 11 is located within the housing 10 and forms a first channel 41a. The bracket 30 is located within the housing 10 and has a second channel 41b. The second channel 41b communicates with the first channel 41a to form a smoke channel 41. Thus, the airway wall 11 and the bracket 30 form a smoke channel structure 3. A liquid storage chamber 42 is formed between the smoke channel structure 3 and the housing 10. The smoke channel structure 3 is inherently sealed, making the smoke channel 41 and liquid storage chamber 42 independent of each other.

[0055] The stent 30 of this embodiment is made of a sealing material, so that the stent 30 itself has sealing properties. The stent 30 can be directly and tightly connected to the airway wall 11. For example, the sealing material can be plastic, rubber, or other materials.

[0056] Optionally, in this embodiment, the bracket 30 includes a transition portion 31 . The transition portion 31 is provided with a through hole 311 along the length direction of the electronic cigarette cartridge 1 , and the air extraction section 411 and the atomization section 412 are connected through the through hole 311 .

[0057] In this embodiment, the transition portion 31 connects one end of the bracket 30 to the airway wall 11 and one end of the bracket 30 to the cover 20. The through hole 311 in the transition portion 31 connects the air extraction section 411 and the atomization section 412, thereby enabling the user to inhale the aerosol. The airway wall 11 and the cover 20 are disposed on opposite sides of the transition portion 31.

[0058] Since the bracket 30 and the cover body 20 enclose the atomization section 412, the process of atomizing the e-liquid to form smoke occurs in the area enclosed by the transition portion 31, the bracket 30 connected to the cover body 20, and the cover body 20. When the smoke flows through the through hole 311 as the user inhales, it enters the suction section 411, and then mixes with the outside air to form an aerosol that flows to the air outlet.

[0059] In this embodiment, 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.

[0060] Optionally, the bracket 30 further includes a first cylinder 32, which is disposed on a side of the transition portion 31 facing the airway wall 11 and connected to the transition portion 31. The first cylinder 32 is fixed to the opening of the through hole 311, and the first cylinder 32 is connected to the airway wall 11, and the first cylinder 32 and the airway wall 11 enclose an air extraction section 411.

[0061] According to this embodiment, the first cylinder 32 is used to connect to the airway wall 11, and the air extraction section 411 is connected to the atomization section 412 through the through hole 311. When the user inhales, the smoke flows through the through hole 311, enters the air extraction section 411, and then flows through the air extraction section 411 to be inhaled by the user.

[0062] 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 restrictions 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.

[0063] Optionally, the bracket 30 further includes a second barrel 33, which is disposed on a side of the transition portion 31 facing away from the first barrel 32 (or facing the cover 20) and is connected to the transition portion 31. The second barrel 33 is fixed to the opening of the through hole 311 and is connected to the cover 20. The second barrel 33 and the cover 20 enclose atomizing section 412.

[0064] In this embodiment, the second barrel 33 is connected to the cover 20; the first barrel 32 and the second barrel 33 are disposed opposite each other. The process of atomizing the e-liquid to form smoke occurs within the area enclosed by the transition portion 31, the second barrel 33, and the cover 20. The smoke then flows through the through hole 311, enters the suction section 411, and is inhaled by the user.

[0065] Optionally, the electronic cigarette cartridge 1 includes an atomizer assembly 50, and the cover body 20 includes a lower cover assembly 22. The lower cover assembly 22 is connected to the housing 10, and the atomizer assembly 50 is sandwiched between the bracket 30 and the lower cover assembly 22 along the length direction of the electronic cigarette cartridge 1. The atomizer assembly 50 is disposed in the smoke channel 41.

[0066] In the embodiment of the present application, the atomizer assembly 50 is used to atomize the e-liquid to form smoke for the user's use. The lower cover assembly 22 is connected to the housing 10 to form the accommodating chamber 40. The lower cover assembly 22 is also configured to provide a position limit for the atomizer assembly 50. Specifically, the atomizer assembly 50 generally includes an oil guide 51 and a heating wire 52. Part of the oil guide 51 is disposed within the atomizing section 412. Both ends of the oil guide 51 extend into the liquid storage chamber 42. The heating wire 52 is wound around a portion of the oil guide 51.

[0067] The oil guide member 51 can be a cotton core, a portion of which can be located in the liquid storage chamber 42, and another portion of which can be located in the atomization section 412. Utilizing the cotton core's ability to absorb liquid, the atomization assembly 50 can transport the liquid in the liquid storage chamber 42 to the atomization section 412 for atomization through the cotton core. For example, the cotton core can be a long, liquid-absorbing cotton, which can extend in the left and right directions. The two ends of the cotton core can extend into the liquid storage chamber 42 from corresponding notches, and the middle 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. The cotton core can absorb the liquid until it reaches a saturated state, thereby transporting the liquid from the liquid storage chamber 42 to the atomization section 412 for liquid atomization.

[0068] The heating wire 52 can be a heating metal wire that generates heat to atomize the e-liquid on the cotton wick. The bracket 30 and the lower cover assembly 22 clamp the atomizer assembly 50 along the length of the electronic cigarette cartridge 1 to limit the position of the atomizer assembly 50 and prevent adverse effects caused by displacement of the atomizer assembly 50 during use. In this embodiment of the present application, the cooperation between the bracket 30 and the lower cover assembly 22 can achieve the fixation of the atomizer assembly 50 in the accommodating chamber 40 without adding new components, which has the beneficial effect of reducing the space occupied by the accommodating chamber 40.

[0069] The end surface of the lower cover assembly 22 near the atomizer assembly 50 can be provided with a groove for securing the atomizer assembly 50. The groove is provided on the end surface of the lower cover assembly 22 facing the atomizer assembly 50, and the atomizer assembly 50 is secured by the groove. The securing structure is simple and highly stable. The groove can be formed into an arc-shaped groove that matches the outer surface of the cotton wick. The end of the cotton wick can be mounted in the groove, and the groove is used to position and secure the cotton wick.

[0070] Optionally, the lower cover assembly 22 includes a lower cover body 221 and a conductive pin 222. The lower cover body 221 defines an electrode hole 2211 and a wiring hole 2212. The electrode hole 2211 communicates with the liquid storage chamber 42. The conductive pin 222 passes through the electrode hole 2211. The heating wire 52 of the atomizer assembly 50 passes through the wiring hole 2212 and is electrically connected to the conductive pin 222.

[0071] According to this embodiment, the lower cover body 221 is used to connect and cooperate with the housing 10 to form the accommodating chamber 40, and the conductive nail 222 is used to connect to the heating wire 52 of the atomizer assembly 50 to heat the heating wire 52. At the same time, the conductive nail 222 also seals the liquid storage chamber 42, which has the function of preventing the leakage of the tobacco oil in the liquid storage chamber 42. The wiring hole 2212 is used to provide a placement space for the heating wire 52 of the atomizer assembly 50. Specifically, the heating wire 52 passes through the wiring hole 2212 and extends into the electrode hole 2211. When the electrode hole 2211 is inserted into the electrode hole 2211, the heating wire 52 contacts the electrode to heat the heating wire 52. In addition, passing the heating wire 52 of the atomizer assembly 50 through the wiring hole 2212 has the beneficial effect of limiting and guiding the heating wire 52, preventing the easily deformed heating wire 52 from deforming or detaching from the conductive nail 222 and becoming ineffective.

[0072] The lower cover assembly 22 may also include a first sealing ring 224. The first sealing ring 224 is used to seal between the lower cover body 221 and the housing 10, preventing the e-liquid in the liquid storage chamber 42 from leaking out of the connection between the lower cover body 221 and the housing 10. Specifically, the first sealing ring 224 is sleeved around the outer periphery of the lower cover body 221. The lower cover body 221 includes an outer wall facing the housing 10, and the housing 10 includes an inner wall facing the lower cover body 221. It will be appreciated that in actual use, the outer and inner walls fit together to form a mating surface between the housing 10 and the lower cover body 221. Furthermore, the first sealing ring 224 is sandwiched between the outer and inner walls and sleeved around the outer periphery of the lower cover body 221. The first sealing ring 224 is deformable. When the outer and inner walls are simultaneously squeezed against each other, the first sealing ring 224 deforms to seal between the outer and inner walls, thereby preventing e-liquid from leaking out of the liquid storage chamber 42 along the gap between the outer and inner walls.

[0073] Optionally, the electrode hole 2211 includes a first hole 2211a and a second hole 2211b that are coaxial and continuous. The diameter of the first hole 2211a is smaller than that of the second hole 2211b, and the first hole 2211a is located on the side of the second hole 2211b that is closer to the bracket 30. The lower cover body 221 has a transition surface 2211c perpendicular to the axis of the electrode hole 2211 at the junction of the first hole 2211a and the second hole 2211b.

[0074] According to this embodiment, the electrode hole 2211 is a stepped hole arranged along the rectangular direction of the electronic cigarette cartridge 1, and the aperture of the first hole 2211a close to 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 also has a stepped structure. In addition, since the electrode hole 2211 is a stepped hole, a transition surface 2211c can be formed at the location where the first hole 2211a and the second hole 2211b are connected.

[0075] Furthermore, during the assembly process, the oil guide 51 is first assembled to the lower cover assembly 22, and the heating wire 52 is bent through the wiring hole 2212 to the position of the conductive nail 222 and contacts the conductive nail 222. The bracket 30 is then assembled to the lower cover assembly 22. The bracket 30 and the lower cover assembly 22 are interference fit, which can prevent oil leakage. The next step is to inject tobacco oil into the liquid storage chamber 42 from the electrode hole 2211. After the tobacco oil is injected, the conductive nail 222 is installed 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 to the process of injecting oil first 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.

[0076] Because the accommodating chamber 40 contains fewer components and the atomizing section 412 is significantly larger, the atomized e-liquid can fully combine with the outside air to form an aerosol, providing a better user experience. Furthermore, the conductive pin 222 and the heating wire 52 are directly assembled to the lower cover body 221. The lower cover body 221 directly positions the oil guide 51 and the conductive pin 222, significantly shortening the assembly dimension chain and ensuring contact between the heating wire 52 and the conductive pin 222, effectively solving the problem of poor contact.

[0077] Optionally, the conductive nail 222 includes a coaxial and interconnected first conductive portion 2221 and a second conductive portion 2222. The diameter of the first conductive portion 2221 is smaller than the diameter of the second conductive portion 2222. The first conductive portion 2221 is disposed at the end of the second conductive portion 2222 adjacent to the bracket 30. The first conductive portion 2221 fits into the first hole 2211a, and the second conductive portion 2222 fits into the second hole 2211b.

[0078] According to the present application, since the electrode hole 2211 and the liquid storage chamber 42 are connected, the conductive nail 222 is also used to seal the liquid storage chamber 42 without adding any new components to the accommodating chamber 40, preventing the leakage of the e-liquid therein. In this embodiment, the first conductive portion 2221 engaged with the first hole 2211a and the second conductive portion 2222 engaged with the second hole 2211b achieve the beneficial effect of preventing the leakage of e-liquid from the liquid storage chamber 42 without adding any new components to the accommodating chamber 40.

[0079] Furthermore, the conductive nail 222 may also include a second sealing ring 2223. The second sealing ring 2223 is used to enhance the sealing performance of the second conductive part 2222 and the lower cover 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 clamped between the second conductive part 2222 and the second hole 2211b. The second sealing ring 2223 has the function of blocking the fitting gap between the second sealing ring 2223 and the second hole 2211b. Furthermore, the second sealing ring 2223 can be deformed. When the second conductive part 2222 and the second hole 2211b are interference fit, the second sealing ring 2223 clamped between the second conductive part 2222 and the second hole 2211b is deformed to achieve sealing of the fitting gap between the second sealing ring 2223 and the second hole 2211b. In the event that the seal 223 fails, the tobacco oil may enter the electrode hole 2211 from the liquid storage chamber 42 , and the second sealing ring 2223 can prevent the tobacco oil from leaking out of the electrode hole 2211 to the outside of the electronic cigarette cartridge 1 .

[0080] Optionally, a preset gap is provided between the surface of the second conductive portion 2222 facing the bracket 30 and the transition surface 2211c. The preset gap is used to provide a placement space for the heating wire 52. In actual applications, due to the low precision of the processing technology, the length of the heating wire 52 cannot be accurately within the actually required length range. Usually, after the heating wire 52 contacts the conductive nail 222, there is still a long section of the heating wire 52 that is not used. The unused heating wire 52 can be set in the preset gap, and there is no need to further shorten the heating wire 52, which has the beneficial effect of improving production efficiency and benefiting the heating wire 52.

[0081] Optionally, the lower cover assembly 22 further includes a sealing member 223 . The sealing member 223 is disposed in the first hole 2211 a and is sandwiched between the lower cover body 221 and the first conductive portion 2221 .

[0082] According to this embodiment, the seal 223 is used to prevent the leakage of tobacco oil from the gap between the conductive pin 222 and the electrode hole 2211. The seal 223 isolates the conductive pin 222 from the tobacco oil in the liquid storage chamber 42, preventing the tobacco 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.

[0083] Optionally, in this embodiment, an electronic cigarette is further provided, which includes the electronic cigarette cartridge 1 as described above.

[0084] Second embodiment

[0085] Previous e-cigarette cartridges lacked independent ventilation structures. Designs that relied solely on the cotton wick in the atomizer assembly for ventilation made it difficult to control the rate of liquid penetration and find a suitable balance, which easily led to problems such as burnt wicks or oil explosions. This application addresses the lack of independent ventilation structures in previous e-cigarette cartridges by providing an independent ventilation structure. This allows for better control of the pressure difference between the liquid reservoir and the outside world, thereby improving the user experience.

[0086] Referring to Figures 3 to 8, the second embodiment of the present application provides an electronic cigarette cartridge 2. The electronic cigarette cartridge 2 of the second embodiment has a structure and / or construction that is substantially the same as some components of the electronic cigarette cartridge 1 of the first embodiment. The electronic cigarette cartridge 2 includes a shell 10, a cover 20, a bracket 130 and an atomizer assembly 50. The cover 20 is fixedly connected to the shell 10, and the bracket 130 is fixedly connected to the cover 20. Specifically, the shell 10 is provided with an airway wall 11; the bracket 130 includes a connecting portion 131, and the connecting portion 131 is fixedly connected to the airway wall 11. The airway wall 11 and the bracket 130 separate the inner cavity 12 of the shell 10 into a smoke channel 41 and a liquid storage chamber 42. The atomizer assembly 50 is sandwiched between the bracket 130 and the cover 20, and the atomizer assembly 50 is arranged in the smoke channel 41.

[0087] The cover 20 and the housing 10 are interference-fitted to prevent the leakage of the e-liquid. The bracket 130 presses the atomizer assembly 50 onto the cover 20 , and the cover 20 and the bracket 130 cooperate to fix the atomizer assembly 50 .

[0088] The electronic cigarette cartridge 2 also includes an openable and closable adjustment member 60. A vent 101 is defined in the airway wall 11 or the connecting portion 131, connecting the smoke channel 41 to the liquid storage chamber 42. The adjustment member 60 is positioned within the vent 101, on the side of the vent 101 facing the liquid storage chamber 42.

[0089] According to this embodiment, the smoke channel structure 3 is provided with a ventilation structure 4 , which includes a vent 101 and an openable and closable adjustment member. The adjustment member is used to open and close the vent 101 .

[0090] According to this embodiment, the vent 101 connects the flue gas passage 41 and the liquid storage chamber 42, thereby connecting the outside atmosphere and the liquid storage chamber 42. This allows airflow in the liquid storage chamber 42 and the outside atmosphere to flow through, thereby achieving pressure balance between the liquid storage chamber 42 and the outside atmosphere. The regulating member 60 can be opened and closed to open and close the vent 101. Thus, the coordination between the vent 101 and the regulating member 60 can adjust the intake rate of gas entering the liquid storage chamber 42 from the vent 101, thereby balancing the pressure between the liquid storage chamber 42 and the flue gas passage 41. Specifically, when the pressure in the smoke channel 41 is greater than the pressure in the liquid storage chamber 42, since the regulating member 60 is arranged at the end of the vent 101 facing the liquid storage chamber 42, the regulating member 60 opens the vent 101 under the action of the pressure difference between the two, and the aerosol in the smoke channel 41 enters the liquid storage chamber 42; when the pressure in the smoke channel 41 is less than the pressure in the liquid storage chamber 42, the regulating member 60 covers the vent 101 under the action of the pressure difference between the two.

[0091] This embodiment controls the flow of aerosol from the smoke passage 41 into the liquid storage chamber 42 to balance the pressure difference between the liquid storage chamber 42 and the smoke passage 41, allowing the liquid in the liquid storage chamber 42 to uniformly penetrate into the atomizer assembly 50 for atomization. This prevents excessive atomized liquid from causing oil spillage and oil inlet, or insufficient oil from causing insufficient smoke, thereby improving the user experience.

[0092] It should be noted that the bracket 130 can be made of plastic. Using plastic can form a seal with the housing 10, preventing liquid leakage. In actual use, atomized liquid requires heating, and plastic is also heat-resistant and not easily affected by high temperatures. This means that even if the plastic bracket 130 is in close proximity to or in contact with high-temperature components, it will not deform or melt due to the high temperature, thereby preventing odor.

[0093] It should also be noted that, as shown in Figure 6, the aperture of the vent 101 is L, where 0.5mm≤L≤1.5mm. Specifically, the vent 101 can be set to one or more. The cross-sectional shape of the vent 101 is variable, and can be circular, square, elliptical or irregular, etc. The side length of the cross section of the square vent can be greater than or equal to 0.5mm and less than or equal to 1.5mm. At this time, the flow rate of the aerosol flowing into the vent 101 from the smoke channel 41 can prevent the liquid storage chamber 42 from being in a negative pressure state, and can also prevent the oil accumulation on the oil guide 51 due to excessive flow rate.

[0094] Optionally, the bracket 130 further includes a bracket body 132, which includes an atomizing chamber wall 321. The atomizing chamber wall 321 is connected to the side of the connecting portion 131 facing away from the airway wall 11. The smoke channel 41 includes an exhaust section 411 and an atomizing section 412 that are interconnected. The atomizing chamber wall 321 encloses the atomizing section 412, and the airway wall 11 encloses the exhaust section 411.

[0095] According to this embodiment, in actual use, the e-liquid is atomized into smoke in the atomization section 412. The atomization chamber wall 321 is used to enclose the atomization section 412. As the user inhales, the smoke flows from the atomization section 412 to the air extraction section 411, then flows along the air extraction section 411 to the air outlet, and is ultimately inhaled by the user. The atomization section 412 enclosed by the atomization chamber wall 321 and the air extraction section 411 enclosed by the airway wall 11 are interconnected, allowing the user to inhale the smoke formed in the atomization section 412.

[0096] Optionally, the bracket body 132 further includes a transition portion 322, which is sandwiched between the connecting portion 131 and the atomizing chamber wall 321 along the length of the electronic cigarette cartridge 2. The transition portion 322 defines a first hole 3221 along the length of the electronic cigarette cartridge 2; the connecting portion 131 is fixed to the opening of the first hole 3221, and the air extraction section 411 and the atomizing section 412 are connected through the first hole 3221.

[0097] According to this embodiment, the transition portion 322 is used to achieve the connection between the connecting portion 131 and the atomizing chamber wall 321, and the first hole 3221 provided on the transition portion 322 is used to achieve the connection between the atomizing section 412 and the exhaust section 411. Specifically, the connecting portion 131 and the atomizing chamber wall 321 are relatively arranged on both sides of the transition portion 322, and the connecting portion 131 and the atomizing chamber wall 321 are indirectly connected to each other through the transition portion 322. Since the atomizing chamber wall 321 encloses the atomizing section 412 and the airway wall 11 encloses the exhaust section 411, it can be understood that the process of atomizing the e-liquid to form smoke occurs in the area enclosed by the transition portion 322 and the atomizing chamber wall 321. When the smoke flows through the first hole 3221 as the user inhales, it enters the area enclosed by the transition portion 322 and the connecting portion 131, and then mixes with the outside air to form an aerosol and flows to the air outlet.

[0098] Optionally, the bracket body 132 also includes an enclosing portion 323, which is connected to the side of the transition portion 322 away from the connecting portion 131, and the enclosing portion 323 is arranged on the periphery of the atomization chamber wall 321. The enclosing portion 323 and the atomization chamber wall 321 enclose a liquid flow chamber 324, and the enclosing portion 323 is away from the outer wall of the liquid flow chamber 324 and contacts the inner wall of the shell 10.

[0099] According to this embodiment, the liquid flow chamber 324 is used to provide a flow channel for the tobacco oil in the liquid storage chamber 42, thereby directing the tobacco oil in the liquid storage chamber 42 to the location where the tobacco oil is atomized. The tobacco oil stored in the liquid storage chamber 42 enclosed by the housing 10 can flow into the liquid flow chamber 324.

[0100] It should be noted that a first sealing ring 70 may be sleeved around the periphery of the enclosure 323. The first sealing ring 70 is sandwiched between the outer wall of the enclosure 323 facing away from the liquid flow cavity 324 and the inner wall of the housing 10. The first sealing ring 70 is deformable. When the outer wall of the enclosure 323 facing away from the liquid flow cavity 324 and the inner wall of the housing 10 are simultaneously squeezed relative to each other, the first sealing ring 70 deforms to achieve a seal between the outer wall of the enclosure 323 facing away from the liquid flow cavity 324 and the inner wall of the housing 10, thereby preventing e-liquid from leaking from the gap between the outer wall of the enclosure 323 facing away from the liquid flow cavity 324 and the inner wall of the housing 10.

[0101] Optionally, the transition portion 322 is further provided with a second hole 3222 along the length direction of the electronic cigarette cartridge 2 ; the liquid storage chamber 42 and the liquid flow chamber 324 are connected through the second hole 3222 .

[0102] The second hole 3222 is used to achieve communication between the liquid storage chamber 42 and the liquid flow chamber 324, and the liquid flow chamber 324 is used to provide a flow channel for the tobacco oil in the liquid storage chamber 42. In actual applications, the tobacco oil is usually atomized by an atomizer assembly 50, and the atomizer assembly 50 generally includes an oil guide member 51 for adsorbing the tobacco oil. Part of the oil guide member 51 extends into the liquid flow chamber 324 to achieve adsorption of the tobacco oil. Specifically, the tobacco oil in the liquid storage chamber 42 enters the liquid flow chamber 324 through the second hole 3222 and is then adsorbed by the oil guide member 51. The atomizer assembly 50 also includes a heating wire 52 wound around the oil guide member 51. The heating wire 52 generates heat to atomize the tobacco oil adsorbed on the oil guide member 51.

[0103] Specifically, the transition portion 322 can have one second hole 3222, or two oppositely arranged second holes 3222, or a plurality of evenly distributed second holes 3222. The number and specific opening positions of the second holes 3222 can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0104] Optionally, the adjusting member 60 is a cylindrical structure including a first cylindrical portion 61 having a deformable movable portion 611. The first cylindrical portion 61 is sleeved onto the side of the connecting portion 131 facing the liquid storage chamber 42, and the movable portion 611 covers the area where the vent 101 is located. The movable portion 611 has a certain degree of deformation and can be deformed by air pressure.

[0105] The cylindrical adjustment member 60 can be sleeved onto the connecting portion 131, facilitating the connection between the adjustment member 60 and the connecting portion 131. The movable portion 611 of the first cylindrical portion 61 is used to close or open the vent 101. When the pressure within the flue gas passage 41 is lower than the pressure within the liquid storage chamber 42, the movable portion 611 closes the vent 101. At this point, smoke in the flue gas passage 41 cannot enter the liquid storage chamber 42 through the vent 101.

[0106] Optionally, the first cylindrical portion 61 is provided with two slits 6111 extending in a direction parallel to the central axis of the first cylindrical portion 61. The slits 6111 extend to one end surface F of the first cylindrical portion 61, so that the length of the slits 6111 is less than the height of the first cylindrical portion 61; the portion of the first cylindrical portion 61 between the two slits 6111 forms a movable portion 611.

[0107] The slit 6111 is used to release the partial constraints of the movable part 611 by other parts of the first barrel 61. When there is a pressure difference between the two sides of the movable part 611, that is, between the smoke channel 41 and the liquid storage chamber 42, the movable part 611 can be moved by the air pressure. For example, when the pressure in the smoke channel 41 is greater than the pressure in the liquid storage chamber 42, the movable part 611 is moved in the direction away from the vent 101 by the air pressure, and the aerosol in the smoke channel 41 can enter the liquid storage chamber 42 from the vent 101 to achieve pressure balance between the smoke channel 41 and the liquid storage chamber 42. When the pressure in the smoke channel 41 is lower than the pressure in the liquid storage chamber 42, the movable part 611 is covered by the air pressure on the vent 101 to prevent the aerosol in the smoke channel 41 from entering the liquid storage chamber 42 from the vent 101.

[0108] Under the action of the pressure difference, the movable portion 611 can open or close the vent 101, specifically adjusting the pressure balance within the smoke channel 41 and the liquid storage chamber 42, thereby allowing the tobacco liquid in the liquid storage chamber 42 to penetrate the atomizer assembly 50 at a uniform rate for atomization. This can prevent excessive atomized tobacco liquid from causing oil explosion and tobacco liquid inlet, or insufficient tobacco liquid from causing insufficient smoke production, thereby improving the user experience.

[0109] It should be noted that the length of the slit 6111 is smaller than the height of the first barrel 61, so that part of the movable part 611 can be connected to other parts of the first barrel 61. That is to say, the other parts of the first barrel 61 also have partial constraints on the movable part 611, and can achieve connection with the movable part 611 while the movable part 611 can move with the pressure difference between the smoke channel 41 and the liquid storage chamber 42, thereby preventing the movable part 611 from falling off and leaving the location of the vent 101.

[0110] Furthermore, there is an overlap width H between the movable portion 611 and the edge of the vent hole 101 (see FIG6 ), and the overlap width H is greater than or equal to 0.3 mm and less than or equal to 1.0 mm. Specifically, the overlap width H is along the length direction of the electronic cigarette cartridge 2 .

[0111] It should be noted that when H is less than 0.3 mm, the width of the overlapping portion is small, which may easily lead to a large gap between the movable portion 611 and the edge of the vent 101 when the movable portion 611 closes the vent 101. The aerosol in the smoke channel 41 can easily enter the liquid storage chamber 42, resulting in excessive accumulation of smoke oil on the oil guide 51. This may further cause the heating wire 52 to fail to atomize in time, resulting in oil explosion and affecting the experience of smoke entering the mouth.

[0112] When H>1.0mm, the width of the overlapped portion is large, which may easily lead to the gap between the movable portion 611 and the edge of the vent 101 being too small when the movable portion 611 opens the vent 101, making it difficult for the aerosol in the smoke channel 41 to enter the liquid storage chamber 42; it will be difficult to timely balance the pressure difference between the liquid storage chamber 42 and the smoke channel 41 through the vent 101, resulting in poor ventilation of the liquid storage chamber 42; the tobacco oil in the liquid storage chamber 42 is difficult to completely infiltrate the oil guide 51 under the action of negative pressure, resulting in a low amount of smoke atomized by the heating wire 52 and a poor smoke taste; and the heating of the heating wire 52 at this time may cause the cotton core to burn dry, resulting in a burnt smell when inhaling. According to the limitation of the overlapped width, this embodiment can improve the accuracy of controlling the pressure difference between the inside and outside of the electronic cigarette cartridge, thereby improving the user experience.

[0113] Furthermore, as shown in Figure 6, the thickness of the movable part 611 is R, where 0.4mm≤R≤0.8mm. The movable part 611 within the above thickness range can open the vent 101 to satisfy the aerosol in the smoke channel 41 to enter the liquid storage chamber 42, and can also achieve the effect of timely ventilation without oil leakage. If the thickness of the movable part 611 is less than 0.4mm, the processing of the movable part 611 will be more difficult. If the thickness of the movable part 611 is greater than 0.8mm, the force required for the movable part 611 to open the vent 101 will be greater. Therefore, this embodiment can improve the accuracy of controlling the pressure difference between the inside and outside of the electronic cigarette cartridge, thereby improving the user experience.

[0114] Furthermore, the thickness R of the movable portion 611 may be greater than or equal to 0.4 mm and less than or equal to 0.5 mm. For example, the thickness R of the movable portion 611 may be 0.4 mm, 0.45 mm, 0.55 mm, 0.6 mm, 0.7 mm, etc., to further improve the effect of ventilation without oil leakage.

[0115] Optionally, the cylindrical structure further includes a second cylindrical portion 62; the second cylindrical portion 62 is connected to the first cylindrical portion 61 and located within the first cylindrical portion 61. A connecting groove 63 is formed between the inner wall of the first cylindrical portion 61 and the outer wall of the second cylindrical portion 62. The connecting portion 131 is inserted into the connecting groove 63. The second cylindrical portion 62 is sandwiched between the airway wall 11 and the connecting portion 131.

[0116] The second barrel portion 62 facilitates the connection between the cylindrical structure and the connecting portion 131. At the same time, the second barrel portion 62 also improves the sealing between the airway wall 11 and the connecting portion 131, preventing the smoke oil in the liquid storage chamber 42 from leaking from between the airway wall 11 and the connecting portion 131. Compared to the first barrel portion 61, the second barrel portion 62 is closer to the airway wall 11. A connecting groove 63 is formed between the inner wall of the first barrel portion 61 and the outer wall of the second barrel portion 62. The connecting groove 63 is used to connect to the connecting portion 131. Specifically, the connecting portion 131 is inserted into the connecting groove 63 to achieve the connection between the cylindrical structure and the connecting portion 131. The second barrel portion 62 is sandwiched between the airway wall 11 and the connecting portion 131. The connecting portion 131 and the airway wall 11 are simultaneously pressed against each other. The second barrel portion 62 can form a seal between the connecting portion 131 and the airway wall 11, preventing the smoke oil from leaking from the gap between the connecting portion 131 and the airway wall 11.

[0117] It should be noted that the other parts of the cylindrical structure except the movable part 611 also have a certain degree of deformation ability. When the connecting part 131 and the airway wall 11 are pressed against each other, the second cylindrical part 62 can deform to achieve a seal between the connecting part 131 and the airway wall 11.

[0118] Alternatively, the regulating member 60 is a diaphragm structure; a portion of the edge of the diaphragm structure is fixedly connected to the location of the vent hole 101 .

[0119] The diaphragm structure is designed to move in response to the pressure differential between the flue gas passage 41 and the liquid storage chamber 42, thereby opening or closing the vent 101. A portion of the diaphragm structure's edge is fixedly connected to the portion where the vent 101 is located. In other words, the diaphragm structure can be disposed on the airway wall 11 or the connection portion 131 where the vent 101 is located. The diaphragm structure can move in response to the pressure differential between the flue gas passage 41 and the liquid storage chamber 42.

[0120] When the pressure in the smoke channel 41 is greater than the pressure in the liquid storage chamber 42, the diaphragm structure moves away from the vent 101 under the action of the air pressure, allowing the smoke aerosol in the smoke channel 41 to enter the liquid storage chamber 42 through the vent 101, thereby achieving pressure balance between the smoke channel 41 and the liquid storage chamber 42. When the pressure in the smoke channel 41 is less than the pressure in the liquid storage chamber 42, the diaphragm structure is covered by the air pressure to prevent the smoke aerosol in the smoke channel 41 from entering the liquid storage chamber 42 through the vent 101.

[0121] Under the influence of the pressure difference, the diaphragm structure can open or close the vent 101, specifically adjusting the pressure balance within the smoke channel 41 and the liquid storage chamber 42, thereby allowing the tobacco liquid in the liquid storage chamber 42 to penetrate the atomizer assembly 50 at a uniform speed for atomization. This can avoid excessive atomized tobacco liquid causing oil explosion and tobacco liquid inlet, or insufficient tobacco liquid causing insufficient smoke production, thereby improving the user experience.

[0122] It should be noted that the edge of the diaphragm structure may be bonded to the airway wall 11 or the connecting portion 131 , or may be connected via a connecting piece, and this embodiment does not impose any limitation on this.

[0123] It should also be noted that the diaphragm structure is relatively light and can move under the action of a pressure difference. This embodiment does not impose any restrictions on the specific material and weight of the diaphragm structure, and it can open and close the vent 101 under the action of a pressure difference.

[0124] Optionally, the cover body 20 may include, in addition to the lower cover assembly 73, a first bracket 71 and a second bracket 72 that are sequentially connected. The lower cover assembly 73 is disposed at the opening of the housing 10, and the bracket 130 presses the atomizer assembly 50 against the first bracket 71, and the bracket 130 and the first bracket 71 cooperate to secure the atomizer assembly 50. Specifically, a mounting groove is provided on the end surface of the first bracket 71 facing the atomizer assembly 50, and the atomizer assembly 50 is secured by the mounting groove, which has a simple fixing structure and high stability.

[0125] Furthermore, the lower cover assembly 73 may include a lower cover body 74, a second sealing ring 75, a liquid absorbing member 76, a receiving member 77, and a conductive pin 78. The lower cover body 74 has a connection hole, and the conductive pin 78 is connected to the connection hole. The second sealing ring 75 is sleeved around the outer periphery of the lower cover body 74 and sandwiched between the lower cover body 74 and the housing 10. The second sealing ring 75 is used to achieve a seal between the lower cover body 74 and the housing 10, preventing the smoke liquid in the liquid storage chamber 42 from leaking from the connection between the lower cover body 74 and the housing 10. In addition, the lower cover body 74 also has an air inlet that is open to the outside atmosphere. The air inlet is connected to the smoke channel 41. A receiving member 77 is provided on the end of the air inlet facing the atomization chamber. The bottom of the atomization section 412 may be provided with a liquid absorbing member 76. The liquid absorbing member 76 is arranged on the side of the receiving member 77 facing the atomization section 412. The liquid absorbing member 76 can be used to collect condensed liquid in the atomization section 412.

[0126] Furthermore, the atomizer assembly 50 may include an oil guide 51 and a heating wire 52, at least a portion of the heating wire 52 being spirally wound around the oil guide 51. For example, the oil guide 51 may be a cylindrical member extending horizontally, and the heating wire 52 is wound around the circumference of the oil guide 51 and extends approximately axially therewith. By providing the heating wire 52 on the oil guide 51, when a user draws from an electronic cigarette cartridge, the heating wire 52 can heat the oil guide 51 adsorbed with tobacco liquid, causing the tobacco liquid on the heating wire 52 to atomize and generate smoke. The generated smoke can be mixed with airflow from the outside atmosphere into the atomization chamber and then introduced into the user's mouth through the air outlet. By wrapping the heating wire 52 around the outer surface of the oil guide 51, the contact area between the heating wire 52 and the outer surface of the oil guide 51 can be increased, which is conducive to sufficient atomization of the tobacco liquid on the oil guide 51, increasing the amount of smoke generated by atomization, and improving the taste. On the other hand, it can also improve the stability of the connection between the heating wire 52 and the oil guide 51.

[0127] It should be noted that the oil guide member 51 can be a cotton core, part of the cotton core extends into the liquid flow cavity 324, and part of the cotton core is arranged in the atomization section 412. By utilizing the cotton core's ability to adsorb the oil, the oil in the liquid storage cavity 42 can be transported to the atomization section 412 for atomization.

[0128] Furthermore, the cotton core can be a long strip of liquid-absorbing cotton, which can extend in the left and right directions. The two ends of the cotton core can respectively extend into the liquid flow cavity 324, and the middle part of the cotton core can be located in the atomization section 412. The smoke oil in the liquid flow cavity 324 can gradually penetrate the entire cotton core through the end of the cotton core. The cotton core can absorb the smoke oil until it reaches a saturated state, thereby realizing the transport of the smoke oil from the liquid flow cavity 324 to the atomization section 412 to facilitate liquid atomization.
