Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to a flip-top, cartridge-replaceable, oil-and-core separated electronic cigarette. Background Technology

[0002] Refillable cartridge e-cigarettes extend their lifespan by replacing the cartridges. To prevent leakage before use, cartridges typically employ a separate coil / electrode structure, meaning the e-liquid inlet channel of the atomizer coil is isolated. Therefore, how to easily replace and use the cartridges with a separate coil / electrode is a challenge for e-cigarettes. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a flip-top type e-cigarette with a separate oil core and cartridge, which can easily achieve a stable fit between the cartridge and the e-cigarette rod, and can also separate the oil core from the cartridge.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0005] The electronic cigarette includes a cartridge and a device. The cartridge can be axially inserted into one side of the device. The device includes a shell and a mouthpiece. The top of the shell is flush with the cartridge. The mouthpiece is swivelly connected to the side of the shell near the cartridge. The mouthpiece cover is fastened to the top of the cartridge, fixing the insertion connection between the cartridge and the device.

[0006] The tip of the cartridge is provided with a barb on the side away from the cigarette holder; the mouthpiece is provided with a hook hole corresponding to the barb; the barb is inserted into the hook hole to achieve the cooperation between the mouthpiece and the cartridge.

[0007] A locking hole is provided on the side of the nozzle near the outer shell; a switch latch is provided on the top of the outer shell near the side connected to the nozzle; a spring is provided laterally between the switch latch and the outer shell; the spring inserts the front end of the switch latch into the locking hole of the nozzle to limit the rotation of the nozzle relative to the outer shell.

[0008] The e-cigarette cartridge includes an oil tank, an atomizer core assembly, sealing silicone, an oil tank support, and a spring. The atomizer core assembly is axially positioned at the center of the oil tank, with sealing silicone at its lower end. The oil tank support is located within the oil tank below the sealing silicone. The top of the atomizer core assembly is telescopically inserted into the top of the oil tank, and its bottom end protrudes radially outward after passing through the sealing silicone and the oil tank support, forming a two-stage axial fit with the oil tank support. The spring is sleeved around the atomizer core assembly, with its two ends abutting against the step formed by the outward protrusion at the bottom of the atomizer core assembly and the oil tank support, respectively. An oil inlet is located at the lower end of the atomizer core assembly. When the atomizer core assembly and the oil tank support form a first-stage fit near the bottom, the oil inlet is located at the position blocked by the sealing silicone. When the atomizer core assembly and the oil tank support form a second-stage axial fit upward, the atomizer core assembly moves upward, and the oil inlet is located above the sealing silicone, communicating with the internal space of the oil tank.

[0009] The atomizing core assembly has a first-stage mating hook and a second-stage mating hook axially arranged on the side wall of its bottom end that mates with the oil tank bracket; the first-stage mating hook is located axially above the second-stage mating hook; the oil tank bracket has a first-stage mating groove and a second-stage mating groove corresponding to the first-stage mating hook and the second-stage mating hook, respectively; when the first-stage mating hook mates with the first-stage mating groove, the atomizing core assembly and the oil tank bracket form a first-stage mating; when the second-stage mating hook mates with the second-stage mating groove, the atomizing core assembly and the oil tank bracket form a second-stage mating.

[0010] The first-level mating hook and the first-level mating groove are offset from the second-level mating hook and the second-level mating groove in the circumferential direction; the first-level mating groove and the second-level mating groove are flush in the axial direction.

[0011] This invention features a hinged connection between the mouthpiece and the outer shell; by flipping the mouthpiece, a stable connection between the cartridge and the device can be achieved, or a new cartridge can be replaced; overcoming the problems of high cost and insufficient suction power associated with magnetic connections. The cartridge employs a two-stage mating structure, requiring only a simple pressing action to activate it when replacing. The overall structure is simple and easy to operate, achieving activation and cartridge-to-device assembly in a single operation. This design reduces cartridge costs and includes an oil-wick separator to prevent leakage during transport and storage. Attached Figure Description

[0025] like Figures 1 to 11 As shown, the electronic cigarette of this invention includes a cartridge 2 and a device 1. The cartridge 2 can be axially inserted into one side of the device 1.

[0026] The device 1 includes a housing 11 and a mouthpiece 12; the top of the housing 11 is flush with the cartridge 2. The mouthpiece 12 is pivotally connected to the side of the housing 11 closest to the cartridge 2; the mouthpiece 12 covers the top of the cartridge 2, securing the cartridge 2 to the device 1. Specifically, a barb 26 is provided on the top of the cartridge 2 away from the device. The mouthpiece 12 has a hook hole 13 corresponding to the barb 26; the barb 26 engages with the hook hole 13 to achieve the engagement between the mouthpiece 12 and the cartridge 2. Furthermore, a locking hole 14 is provided on the side of the mouthpiece 12 closest to the housing 11; a switch lock 15 is provided on the top of the housing 11 near the side connected to the mouthpiece 12. A spring 16 is horizontally positioned between the switch lock 15 and the housing 11; the spring 16 inserts the front end of the switch lock 15 into the locking hole 14 of the mouthpiece 11, limiting the rotation of the mouthpiece 12 relative to the housing 11.

[0027] When it is necessary to open nozzle 12, such as Figure 5 As shown, move the switch latch 15 to the right; this allows the suction nozzle 12 to rotate relative to the outer casing 11. Then disengage the barb 26 from the hook hole 13; rotate the suction nozzle 12 until... Figure 6 The device should appear as shown; then you can remove cartridge 2. Figure 7 As shown, insert the new cartridge 2 after replacing it. Rotate the mouthpiece 12 back. Figure 4 As shown in the diagram; the barb 26 engages with the hook hole 13, and the spring 16 inserts the front end of the switch latch 15 into the latch hole 14 of the mouthpiece 11; the mouthpiece 12 secures the engagement between the tobacco cartridge 2 and the tobacco rod 1.

[0028] The specific structure of the cigarette cartridge is as follows Figures 8 to 11As shown; the cartridge 2 includes an oil tank 21, an atomizing core assembly 22, a sealing silicone 23, an oil tank support 24, and a spring 25.

[0029] An atomizer core assembly 22 is axially positioned at the center of the oil tank 21, with a sealing silicone 23 at its lower end. An oil tank support 24 is positioned below the sealing silicone 23 within the oil tank. The top of the atomizer core assembly 22 is telescopically inserted into the top of the oil tank 21, and its bottom end, passing through the sealing silicone 23 and the oil tank support 24, protrudes radially outward, forming a two-stage axial fit with the oil tank support 24. A spring 25 is fitted around the atomizer core assembly 22, with its two ends abutting against the step formed by the outward protrusion at the bottom of the atomizer core assembly 22 and the oil tank support 24, respectively. An oil inlet 221 is located at the lower end of the atomizer core assembly 22.

[0030] The bottom end of the atomizing core assembly 22 has a first-stage mating hook 222 and a second-stage mating hook 223 axially arranged on the side wall where it mates with the oil tank bracket 24. The first-stage mating hook 222 is located axially above the second-stage mating hook 223. The oil tank bracket 24 has a first-stage mating groove 241 and a second-stage mating groove 242 corresponding to the first-stage mating hook 222 and the second-stage mating hook 223, respectively. The first-stage mating hook 222 and the first-stage mating groove 241 are offset from the second-stage mating hook 223 and the second-stage mating groove 242 in the circumferential direction; the first-stage mating groove 241 and the second-stage mating groove 242 are flush in the axial direction.

[0031] When the first-stage mating hook 222 mates with the first-stage mating groove 241, the atomizing core assembly 22 and the oil tank bracket 24 form a first-stage mating; the oil inlet 221 is located at the sealing position of the sealing silicone 23; the oil core is in a separated state.

[0032] When the second-stage mating hook 223 mates with the second-stage mating groove 242, the atomizing core assembly 22 and the oil tank bracket 24 form a second-stage mating; the atomizing core assembly 22 moves upward and the oil inlet 221 is located above the sealing silicone 23 and communicates with the internal space of the oil tank 21; the oil core is in the combined and connected state.

[0033] Before the cartridge 2 is assembled with the e-cigarette device 1, the atomizer core assembly 22 and the oil tank support 24 are in a first-stage engagement state; the bottom of the atomizer core assembly 22 is exposed at the bottom of the oil tank 21. During assembly, as the cartridge 2 is pushed downwards, the atomizer core assembly 22 is held in place by the e-cigarette device 1; the oil tank 11 continues to press down, causing the oil tank support 24 and the atomizer core assembly 22 to enter a second-stage engagement. After entering the second-stage engagement, the bottom of the atomizer core assembly 22 is flush with the bottom of the oil tank 21; the oil and core are combined and connected, and the atomizer core assembly 22 cannot be pushed further in; a stable engagement is formed. After fastening the mouthpiece 12, the e-cigarette is ready to use.

[0034] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. The structure of the remaining parts of the electronic cigarette is unrelated to the implementation of the aforementioned scheme; it will not be described in detail here.
