Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to a structure for the separation of the cartridge and the device in an e-cigarette. Background Technology

[0002] In e-cigarettes, e-liquid typically seeps into a reservoir, where it is then atomized by the atomizer coil at the center to create vapor for the user to inhale. Therefore, a channel must be established between the e-liquid and the reservoir during use. However, if this channel remains open even when the e-cigarette is not in use, leakage from the reservoir can easily occur.

[0003] Therefore, a solution is needed that can easily open or close the channel from the e-liquid to the oil-collecting cotton. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a structure for the combination and separation of the e-liquid cartridge and the e-cigarette rod in an e-cigarette; the e-liquid channel to the e-liquid storage cotton can be opened or closed by the combination and separation of the e-liquid cartridge and the e-cigarette rod.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0006] The structure includes a cartridge and a device, the device being inserted into the bottom of the cartridge. The cartridge includes an oil tank, a bottom sealing assembly for the oil tank, an oil pipe assembly, and a copper pipe. The oil tank is hollow, with a tubular section extending inward from the top of the oil pipe assembly, and a bottom sealing assembly at the bottom. The oil pipe assembly contains an atomizing core assembly, with an oil inlet near the bottom. The bottom sealing assembly is fitted with a copper pipe. The bottom of the oil pipe assembly is fitted inside the copper pipe. When the device is not inserted into the cartridge, the oil inlet is located inside the copper pipe. When the device is inserted into the cartridge, the oil inlet is exposed above the copper pipe and communicates with the hollow oil storage space in the oil tank.

[0007] The tubular section at the top of the oil tank has a through hole formed at the center of the top of the oil tank, and a section of circular tube extends inward below the through hole; the diameter of the through hole is smaller than the inner diameter of the circular tube to form a step at the top of the oil tank; the top of the oil pipe assembly is a suction nozzle, the lower end of the suction nozzle protrudes outward to form a convex ring, and a spring is sleeved on the suction nozzle above the convex ring; the two ends of the spring rest on the bottom of the step and the top of the convex ring.

[0008] The convex ring is located inside the circular tube and is sealed to the circular tube.

[0009] The oil tank bottom sealing assembly includes a lower sealing silicone sealant and an oil tank bottom cover; the lower sealing silicone sealant is fitted onto the upper end of the oil tank bottom cover; the lower sealing silicone sealant is sealed to the inner wall of the oil tank; a copper tube is fitted inside the oil tank bottom cover, and the bottom end of the oil tank bottom cover protrudes towards the center to form a limiting ring; the bottom end of the oil tube assembly is limited above the limiting ring.

[0010] The top of the cigarette rod is provided with a cigarette rod cover, and the center of the cover protrudes upward to form a boss; when the cigarette rod is inserted into the cartridge, the boss pushes against the oil pipe assembly of the cartridge and moves upward to the top of the stroke.

[0011] The oil tube assembly includes a stainless steel tube, an oil storage cotton, and a bottom seal; the oil storage cotton is placed inside the stainless steel tube, the bottom is sealed with a bottom seal, and the upper end is connected to a nozzle; an oil inlet is provided on the stainless steel tube corresponding to the lower end of the oil storage cotton; the oil storage cotton is hollow and an atomizing core assembly is installed inside it.

[0012] When the e-cigarette cartridge of this invention is inserted into the e-cigarette holder, the top cover of the holder pushes the oil pipe assembly upward, opening the oil inlet and allowing e-liquid to enter the oil reservoir. When the e-cigarette holder is removed, the oil pipe assembly is pushed downward by spring force to reset, closing the oil inlet and completely separating the e-liquid from the oil reservoir. Therefore, when not in use, it prevents e-liquid from entering the oil reservoir, reducing the occurrence of leakage. Attached Figure Description

[0019] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.

[0020] like Figures 1 to 5 As shown, the combination and separation structure of the electronic cigarette cartridge and the e-cigarette rod of this utility model includes a cartridge 01 and an e-cigarette rod 02, which can be inserted into the bottom of the cartridge 01. The cartridge 01 includes an oil tank 1, an oil tank bottom sealing assembly 4, an oil pipe assembly 2, and a copper pipe 3.

[0021] The oil tube assembly 2 includes a stainless steel tube 23, an oil storage cotton 25, a bottom seal 24, a nozzle 22, a spring 21, and an atomizing core assembly 26. The oil storage cotton 25 is placed inside the stainless steel tube 23, the bottom is sealed with a bottom seal 24, and the nozzle 22 is connected to the upper end. An oil inlet hole 231 is provided on the stainless steel tube 23 corresponding to the lower end of the oil storage cotton 25. The oil storage cotton 25 is hollow and houses the atomizing core assembly 26. The nozzle 22 protrudes outward to form a convex ring 221, and the spring 21 is sleeved on the nozzle 22 above the convex ring 221.

[0022] The oil tank 1 is hollow, with a tubular section formed inward at the top for the suction nozzle 22 at the top of the internal oil pipe assembly 2 to pass through, and an oil tank bottom sealing assembly 4 is provided at the bottom. The tubular section at the top of the oil tank has a through hole formed in the center of the top of the oil tank, and a circular tube 11 extends inward below the through hole; the diameter of the through hole is smaller than the inner diameter of the circular tube to form a step 12 at the top of the oil tank.

[0023] The convex ring 221 of the suction nozzle 22 is located inside the round tube 11 and is sealed to the round tube 11. The two ends of the spring 21 rest below the step 12 and above the convex ring 221.

[0024] The bottom sealing assembly 4 of the oil tank includes a lower sealing silicone 41 and an oil tank bottom cover 42; the lower sealing silicone 41 is fitted onto the upper end of the oil tank bottom cover 42; the lower sealing silicone 41 seals against the inner wall of the oil tank 1; a copper tube 3 is fitted inside the oil tank bottom cover 42. The bottom end of the oil tank bottom cover 42 protrudes towards the center to form a limiting ring 421; the bottom end of the oil tube assembly 2 is limited above the limiting ring 421.

[0025] A top cover 5 is provided at the top of the cigarette rod 02, and a boss 51 is formed by the upward protrusion of the center of the top cover 5.

[0026] When the e-cigarette rod 02 is inserted into the cartridge 01, the boss 51 pushes against the oil pipe assembly 2 of the cartridge 01 and moves it to the top of its stroke. At this time, the oil inlet 231 is located above the copper pipe 3 and is connected to the hollow oil storage space in the oil tank 1; at the same time, the spring 21 is compressed and contracts.

[0027] When the e-cigarette rod 02 is not inserted into the cartridge 01, the spring 21 extends and returns to its uncompressed state; the oil pipe assembly 2 moves towards the oil tank bottom cover 42 and is positioned by the limiting ring 421. The oil inlet 231 is located inside the copper pipe 3 and is sealed by the copper pipe 3. At this time, the channel of e-liquid in the oil tank 1 to the oil storage cotton 25 is closed.

[0028] As shown in the figure, the rest of the electronic cigarette of this utility model is the same as that of existing electronic cigarettes; it will not be described again here.
