[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figures 1 to 6This utility model provides a cartridge 100 for use in combination with a battery assembly 200 to form an electronic cigarette. It includes an oil cup 10 and an atomizing core 20. The oil cup 10 includes an oil storage sleeve 11, a first sealing seat 12, a second sealing seat 13, a sealing cap 14, and a sealing plug 15. One end of the oil storage sleeve 11 forms a mouthpiece 111, and the other end of the oil storage sleeve 11 is provided with a second limiting protrusion 112. The oil storage sleeve 11 contains an oil storage cavity 113 and a smoke outlet 114, which penetrates one end face of the mouthpiece 111. When inhaling vapor, the user inhales through their mouth towards the mouthpiece 111. Furthermore, a first limiting groove 115 is provided on the outer wall of the oil storage sleeve 11. It is understood that the oil storage sleeve 11 can be made of transparent or semi-transparent material, thus facilitating observation of the remaining e-liquid in the oil storage cavity 113 for the user to add e-liquid.

[0028] The first sealing seat 12 is located inside the first end of the oil storage sleeve 11 and is connected to the oil storage sleeve 11 and the atomizing core 20. The first sealing seat 12 is tightly and elastically abuts against the opening at one end of the smoke outlet 114, thus preventing the e-liquid in the oil storage chamber 113 from flowing into the smoke outlet 114, thereby preventing the user from directly inhaling the e-liquid. The second sealing seat 13 is located inside the second end of the oil storage sleeve 11 and elastically abuts against the cavity wall of the oil storage chamber 113, thereby connecting to the oil storage sleeve 11. The second sealing seat 13 corresponds to the cavity opening of the oil storage chamber 113 and is used to seal the cavity opening of the oil storage chamber 113. The first sealing seat 12 and the second sealing seat 13 can be made of elastic materials such as silicone or rubber, thus better preventing e-liquid leakage.

[0029] The sealing cap 14 is placed over one end of the oil storage sleeve 11 and connected to the second sealing seat 13, thus preventing the second sealing seat 13 from deforming or falling off. The sealing cap 14 is provided with an oil filling hole 141 communicating with the oil storage cavity 113. The sealing plug 15 is inserted into the oil filling hole 141 and is detachably connected to the second sealing seat 13. When the e-liquid is exhausted and needs to be added, the cartridge 100 is removed from the battery assembly 200, then the cartridge 100 is inverted, and the sealing plug 15 is pulled out, allowing e-liquid to be injected through the oil filling hole 141. After the e-liquid is injected into the oil storage cavity 113, the sealing plug 15 is reinserted into the oil filling hole 141.

[0030] The atomizing core 20 is located within the oil storage chamber 113 and includes an oil-separating tube 21, a porous oil intake tube 22, a first air vent tube 23, a porous oil guide 24, and a heating element 25.

The first end of the oil-separating tube 21 is connected to the first sealing seat 12, and the second end is connected to the second sealing seat 13. The wall of the oil-separating tube 21 has several first oil inlet holes 211, spaced apart. All the first oil inlet holes 211 form a ring and surround the porous oil intake tube 22. The first oil inlet holes 211 communicate with the oil storage chamber 113, and the e-liquid in the oil storage chamber 113 flows into the oil-separating tube 21 through the first oil inlet holes 211. The oil-separating tube 21 prevents excessive e-liquid from being transported from the oil storage chamber 113 into the atomizing core 20. The oil separator 21 can be a metal tube or a plastic tube, as long as it can block e-liquid. The material is not specifically limited here.

[0031] The porous oil suction tube 22 is located inside the oil separator tube 21 and between the oil separator tube 21 and the first vent tube 23. The outer peripheral surface of the porous oil suction tube 22 elastically abuts against the inner wall surface of the oil separator tube 21 and covers the first oil inlet hole 211.

The porous oil guide 24 is located inside the first vent tube 23 and contacts the porous oil suction tube 22 through the second oil inlet hole 231. The e-liquid in the porous oil suction tube 22 flows into the porous oil guide 24 through the second oil inlet hole 231.

[0032] The porous suction tube 22 and the porous wicking element 24 can be made of porous or fibrous materials. The porosity of the porous suction tube 22 is greater than that of the porous wicking element 24, thus further hindering the flow of e-liquid into the porous wicking element 24 and reducing the probability of e-liquid leakage. In this embodiment, the porous wicking element 24 is formed by winding multiple sheets of non-woven fabric, and it has a hollow tubular structure. The heating element 25 is located inside and in contact with the porous wicking element 24, and is used to atomize the e-liquid at the porous wicking element 24. The heating element 25 can be a heating wire or a heating mesh, etc.

The second air duct 26 is located between the smoke outlet 114 and the heating element 25. One end of the second air duct 26 is connected to the first air duct 23, and the other end is connected to the oil cup 10. The first air duct 23 communicates with the smoke outlet 114 through the second air duct 26. The second air duct 26 has several oil-absorbing pores. Therefore, the second air duct 26 can absorb the condensed e-liquid within the smoke outlet 114, preventing the user from inhaling the condensed e-liquid and improving the user experience. Preferably, the second air duct 26 is formed by braiding fiberglass threads, thus not only absorbing e-liquid but also possessing high toughness and ease of assembly.

[0034] The end of the porous suction tube 22 facing the smoke outlet 114 is fitted onto the second vent tube 26, allowing the e-liquid condensed and recirculated from the smoke outlet 114 to flow into the porous suction tube 22. The first end of the second vent tube 26 is inserted into the first vent tube 23, and the length of the second vent tube 26 is greater than the length of the first vent tube 23. The porous wicking component 24 is in contact with the second vent tube 26. Therefore, the condensed and recirculated e-liquid can flow directly and stably into the porous wicking component 24. Preferably, the first vent tube 23 and the second vent tube 26 are coaxially arranged.

[0035] The support tube 27 is located inside the first vent tube 23 and abuts against the end face of the porous oil guide 24 to prevent the porous oil guide 24 from falling out of the first vent tube 23. The fixing tube 28 is inserted into the oil separator tube 21 and abuts against the porous oil suction tube 22, and the outer wall of the fixing tube 28 is tightly connected to the inner wall of the oil separator tube 21. One end of the first vent tube 23 is inserted into the fixing tube 28 and connected to the fixing tube 28.

[0036] Secondly, this utility model also discloses an electronic cigarette, including a cartridge 100 and a battery assembly 200, wherein the cartridge 100 is the same as the cartridge 100 described above, therefore, the structure of the cartridge 100 of this electronic cigarette will not be described again here. Since the structure of the cartridge 100 of this electronic cigarette is the same as the structure of the cartridge 100 described above, it also has the same technical effect.

[0037] The battery assembly 200 includes a housing 31, an end cap 32, a battery 33, and electrodes 34. The housing 31 is provided with a battery receiving groove 311 and a docking groove 312. The battery receiving groove 311 extends longitudinally along the housing 31, and its opening is located at the first end of the housing 31. The docking groove 312 is arranged parallel to the battery receiving groove 311, with its opening facing the second end of the housing 31. A second limiting groove 3121 is provided on the side wall of the docking groove 312, and a second limiting protrusion 112 extends into the second limiting groove 3121, thus making the electrical connection of the electrodes 34 more reliable and preventing them from falling off. A docking notch 313 extending into the docking groove 312 is provided on the second end face of the housing 31, and a first limiting protrusion 314 extending into the docking notch 313 is provided on the outer wall surface of the housing 31.

[0038] End cap 32 is connected to the first end of housing 31 and covers the opening of battery receiving groove 311. End cap 32 is provided with air inlet 321. Battery 33 is located in battery receiving groove 311. Electrode 34 is electrically connected to battery 33 and extends into docking groove 312. Tobacco cartridge 100 is detachably inserted into docking groove 312 and extends out through docking notch 313. First limiting protrusion 314 extends into first limiting groove 115, thereby improving connection reliability. Electrode 34 extends toward docking notch 313 and extends into tobacco cartridge 100 for electrical connection with tobacco cartridge 100.

[0039] The battery assembly 200 also includes an airflow sensor 35, a first elastic sealing ring 36, a second elastic sealing ring 37, and an air regulating component 39. The airflow sensor 35 is located within the space formed by the housing 31 and the end cap 32 and is used to detect whether the user is inhaling. A first air guide hole 361 is formed within the first elastic sealing ring 36, which is fixed to the bottom wall of the docking groove 312 and elastically abuts against the cartridge 100. The air inlet 321 communicates with the interior of the cartridge 100 via the first air guide hole 361 and is connected to the first air vent 23, thus better preventing air leakage and improving the stability of the air intake.

[0040] The second elastic sealing ring 37 has a second air guide hole 371 that communicates with the airflow sensor 35. The second elastic sealing ring 37 and the first elastic sealing ring 36 are arranged side by side and elastically abut against the cartridge 100. The second air guide hole 371 communicates with the interior of the cartridge 100 and connects to the first air passage 23. When the user inhales the electronic atomizing device, the gas at the airflow sensor 35 flows towards the cartridge 100 through the second air guide hole 371, thereby triggering the airflow sensor 35. Because the second elastic sealing ring 37 and the first elastic sealing ring 36 are arranged side by side and elastically abut against the cartridge 100, air leakage is better avoided, and the inhalation sensitivity is improved. The air regulating component 39 is movably disposed in the space formed by the housing shell 31 and the end cap 32 and extends to the air inlet 321. When it is necessary to adjust the air intake, the air intake can be adjusted by pushing the air regulating component 39 to move laterally towards the end cap 32.

[0041] The battery assembly 200 also includes a first bracket 381, a display screen 382, ​​and a control board 383. The first bracket 381 is inserted into the battery receiving slot 311 and extends into the end cover 32, abutting against the end cover 32, thus making the installation more stable and reliable. The first bracket 381 is provided with a first positioning slot 384 and a second positioning slot 385. The display screen 382 is installed in the first positioning slot 384 for positioning. The display screen 382 can be used to display information such as battery level to help users understand the usage status. The battery 33 is installed in the second positioning slot 385. Therefore, during assembly, the display screen 382 and the battery 33 are first installed on the first bracket 381, and then the first bracket 381 is inserted into the battery receiving slot 311. This not only facilitates assembly but also makes the battery 33 more securely fixed, preventing it from falling out.

[0042] The first bracket 381 extends into the end cap 32 and has a fixing groove 386 at one end. One end of the control board 383 is inserted into the fixing groove 386.

When the e-liquid in the cartridge 100 is exhausted, the cartridge 100 is removed from the docking groove 312 and a new cartridge 100 is replaced.

[0043] In summary, this utility model achieves its goal through the ingenious cooperation of the oil separator 21, the porous oil suction pipe 22, the first vent pipe 23, and the porous oil guide component 24. The oil separator 21 is located inside the oil cup 10, and its wall is provided with a first oil inlet hole 211, which communicates with the oil storage chamber 113. The porous oil suction pipe 22 is located inside the oil separator 21 and covers the first oil inlet hole 211.

The porous oil guide component 24 is located inside the first vent pipe 23 and contacts the porous oil suction pipe 22 through the second oil inlet hole 231. Therefore, the e-liquid in the oil storage chamber 113 first flows into the oil separator 21 from the first oil inlet 211 and is absorbed by the porous oil suction pipe 22. Then, the porous oil guide 24 conducts the e-liquid at the porous oil suction pipe 22 to the heating element 25 for atomization by the heating element 25, thereby avoiding the problem of excessive e-liquid delivery and e-liquid leakage.
