Description

A universal oil bottle enables rapid coil lubrication for electronic cigarettes. Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and specifically to an electronic cigarette that uses a universal oil bottle to achieve rapid filling of the coil. Background Technology

[0002] As a substitute for traditional tobacco, e-cigarettes have seen continuous market demand growth in recent years. Among them, open-system e-cigarettes are favored by many users due to their advantages such as refillability and lower operating costs. However, existing open-system e-cigarette products generally suffer from problems such as cumbersome operation, low refill efficiency, and susceptibility to contamination during the refilling process.

[0003] Traditional e-liquid filling methods mainly rely on manually squeezing the e-liquid bottle or using tools such as droppers to drip e-liquid into the cartridge. This method has obvious drawbacks: First, the filling speed is slow, and the e-liquid relies on gravity to naturally penetrate, resulting in a long coil lubrication time; second, it is difficult to accurately control the filling amount, which can easily lead to insufficient filling causing dry burning or excessive filling causing leakage; third, different brands of cartridges have different interface specifications, and the dedicated e-liquid bottles have poor compatibility.

[0004] Some existing technologies attempt to use air pressure to assist in e-liquid filling, but these often employ complex air pump or piston structures, resulting in bulky, costly devices that are difficult to port. Other technologies use pre-pressurized e-liquid bottles, but these suffer from poor sealing, uncontrollable pressure, and lack of reusability. Furthermore, existing e-liquid bottles are often sold bundled with specific e-cigarette cartridges, preventing cross-brand compatibility and leading to resource waste.

[0005] Therefore, there is an urgent need for a simple, easy-to-operate, efficient, and versatile refilling device to solve the technical challenges of rapid, clean, and precise refilling of open-type electronic cigarettes. Summary of the Invention

[0006] The technical problem solved by this invention is to provide a universal oil bottle for quickly lubricating electronic cigarette cartridges; it enables the universal oil bottle to quickly fill and lubricate electronic cigarette cartridges.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is:

[0008] The electronic cigarette includes a shell, a cartridge, an e-liquid bottle, and an injection / release mechanism. The cartridge is located on the top of the shell, and the injection / release mechanism is located inside the shell. The e-liquid bottle passes through the injection / release mechanism to inject e-liquid into the cartridge. During the process of the e-liquid bottle passing through the injection / release mechanism and connecting to the cartridge, the injection / release mechanism first injects air into the e-liquid bottle so that the e-liquid in the bottle can flow quickly into the cartridge, and then releases air from the e-liquid bottle so that all the e-liquid can be injected into the cartridge.

[0009] The oil bottle has an oil injection needle protruding from the top via a sealing silicone sealant.

[0010] The e-cigarette cartridge includes a mouthpiece, a bottom cap, an oil reservoir, and an atomizing core assembly; the bottom cap is sealed at the bottom of the mouthpiece; an oil reservoir is placed within the space enclosed by the mouthpiece and the bottom cap; the oil reservoir forms an atomization channel corresponding to the mouthpiece opening of the mouthpiece; the atomizing core assembly is placed within the atomization channel; the bottom cap and the oil reservoir are staggered within the atomization channel to form an oil filling channel.

[0011] The outer shell is provided with a cavity below the oil injection channel to accommodate the gas injection and unloading mechanism and the oil bottle; the gas injection and unloading mechanism is provided at the top of the cavity.

[0012] The gas injection and degassing mechanism includes a silicone sealing cavity, an injection needle, and a degassing needle. The silicone sealing cavity forms an injection needle channel through which the oil injection needle of the oil supply bottle passes, corresponding to the oil injection channel. The injection needle is hollow, with one end located inside the silicone sealing cavity and the bottom end exposed outside the silicone sealing cavity. Vent holes are provided in the parts inside and outside the silicone sealing cavity. The degassing needle is hollow, passes through the silicone sealing cavity, with both ends exposed outside the silicone sealing cavity, and a degassing hole is provided near the bottom end.

[0013] The bottom ends of the air injection needle and the air release needle are needle-shaped. During the oil bottle assembly process, the bottom end of the air injection needle passes through the sealing silicone of the oil bottle and is inserted into the oil bottle to introduce the air in the sealing silicone cavity into the oil bottle.

[0014] During and after the oil bottle assembly process, the bottom of the air release needle passes through the sealing silicone of the oil bottle and is inserted into the oil bottle. The air pressure inside and outside the oil bottle is balanced so that the e-liquid is injected into the oil storage cotton under gravity.

[0015] This invention utilizes an air injection needle to rapidly introduce compressed air from the air injection and degassing mechanism into the e-liquid bottle during the initial insertion phase. This forces the e-liquid into the reservoir cotton immediately after insertion, achieving rapid coil lubrication. After the compressed gas is introduced into the e-liquid bottle, the degassing needle balances the pressure inside and outside the bottle, ensuring all e-liquid is injected into the cartridge. Therefore, this invention employs a dual-adjustment structure of air injection and air delivery to achieve rapid coil lubrication and e-liquid filling. Attached Figure Description

[0025] The gas injection and degassing mechanism 4 includes a silicone sealing cavity 41, an injection needle 42, and a degassing needle 43. The silicone sealing cavity 41 forms an injection needle channel 46 through which the oil injection needle of the oil supply bottle passes, corresponding to the oil injection channel 26. The injection needle 42 is hollow, with one end located inside the silicone sealing cavity and the bottom end exposed outside the silicone sealing cavity. Vent holes 44 are respectively provided on the parts inside and outside the silicone sealing cavity 41. The degassing needle 43 is hollow, passes through the silicone sealing cavity 41, with both ends exposed outside the silicone sealing cavity, and a degassing hole 45 is provided near the bottom end.

[0026] As shown in the figure, when the outer shell 1 and the cartridge 2 are in an inverted state, the oil bottle 3 is inverted and passes through the gas injection and degassing mechanism 4 to inject oil into the cartridge.

[0027] As shown in Figure 3, during the process of the oil bottle 3 passing through the gas injection and degassing mechanism 4 and connecting to the e-liquid cartridge 2, the gas in the sealing silicone cavity 41 is compressed, and the bottom end of the gas injection needle 42 passes through the sealing silicone 31 of the oil bottle 3 and is inserted into the oil bottle 3, introducing the air in the sealing silicone cavity 41 into the oil bottle 3; the e-liquid can flow into the e-liquid cartridge 2 quickly.

[0028] During and upon completion of the assembly of the oil bottle 3, the bottom end of the air release needle 43 passes through the sealing silicone 31 of the oil bottle 3 and is inserted into the oil bottle 3. The top end of the air release needle 43 communicates with the space below the oil storage cotton 23. This space is connected through the atomizing core assembly 24 and the mouthpiece 25. By balancing the air pressure inside and outside the oil bottle 3, the e-liquid is injected into the oil storage cotton 23 under gravity. Therefore, all the remaining e-liquid in the oil bottle 3 can be injected into the cartridge 2.

[0029] The structure of the remaining parts of the electronic cigarette of the present invention 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.
