Description

Technical Field

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

[0002] As a vaporization device to replace traditional tobacco, e-cigarettes rely on e-liquid to moisten the atomizing coil for proper operation. Currently, existing e-liquid bottles on the market suffer from the following technical defects:

[0003] First, the products are highly specialized and lack versatility. Most existing e-cigarette bottles are designed specifically for certain brands or models of e-cigarette cartridges, with a structure designed to match the shape of a specific e-liquid reservoir. This makes them unsuitable for the widely used standard cylindrical e-liquid bottles. This specialized design means that users need to carry multiple specialized e-liquid bottles when switching between different brands and models of open-system e-cigarettes, increasing usage costs and inconvenience.

[0004] Second, the filling efficiency is low and the coil lubrication speed is slow. Traditional filling methods mainly rely on gravity flow or simple squeezing to allow e-liquid to enter the e-liquid reservoir cotton. The e-liquid penetration speed is slow, and the coil lubrication time is long, which affects the user experience. Especially when it is necessary to quickly change e-liquid flavors or use it urgently, the current technology is difficult to meet the needs of instant coil lubrication.

[0005] Third, the product has a single function and cannot be used independently. Existing dedicated e-liquid bottles usually need to be used with specific cartridge structures to complete the filling process. They cannot be used as independent tools to provide filling services for other open-type e-cigarette products, which limits the product's applicability and practical value.

[0006] Therefore, there is an urgent need for a versatile, efficient, and self-sustaining e-cigarette filling technology that can quickly lubricate the core of various open-type e-cigarette products, in order to solve the aforementioned problems of existing technologies. Summary of the Invention

[0007] The technical problem solved by this invention is to provide an electronic cigarette cartridge that can be quickly moistened using a universal oil bottle; the cartridge can be quickly moistened, and the oil bottle can be used independently to fill other open-type electronic cigarette products.

[0008] The technical solution of the present invention to solve the above-mentioned technical problems is:

[0009] The electronic cigarette cartridge includes a shell, an atomizing core assembly, a piston support, a bottom cover, an e-liquid bottle, and a mouthpiece cap. An atomization channel is provided on one side of the shell, within which the atomizing core assembly is placed. An axially movable piston support is provided on the other side. An inverted e-liquid bottle can be inserted above the piston support. A mouthpiece cap can be placed over the e-liquid bottle and the shell. A bottom cover is located at the bottom of the atomization channel and below the piston support, forming an activation cavity that communicates with the atomizing core assembly. When the e-liquid bottle is inverted on the piston support, the bottle opens, and e-liquid enters the activation cavity between the piston support and the bottom cover. When the mouthpiece cap is closed, it pushes the e-liquid bottle and piston support downwards, compressing the activation cavity until it is completely compressed.

[0010] The oil bottle consists of a bottle body and a stopper. The top of the bottle body forms the bottle mouth; the outside of the bottle mouth is threaded; and the stopper is inserted into the bottle mouth for sealing.

[0011] The piston support consists of a piston outer support and a piston inner support that cooperate with each other; the piston inner support is located inside the piston outer support.

[0012] The piston outer support is composed of a ring-shaped part. The top of the ring-shaped part protrudes two barbs in a symmetrical arrangement in the circumferential direction with the top facing upward; the hook angles of the barbs face outward; the side wall at the lower end of the ring-shaped part forms two hook openings symmetrically arranged in the circumferential direction, and the bottom end protrudes radially inward to form a connecting ring; correspondingly;

[0013] The piston inner support is composed of a cylindrical part; the upper end of the cylindrical part forms an oil passage that communicates with the inside and outside; the bottom end of the cylindrical part expands radially outward to form a disc; a barb is formed below the disc;

[0014] The disc is inserted into the annular part, and the barb below the disc hooks onto the connecting ring below the piston outer support. The cooperation between the connecting ring and the disc makes the piston outer support and piston inner support form a fixed structure.

[0015] Two barbs protrude symmetrically in a circumferential manner above the disc; the hooks of the barbs face inward; when the oil bottle is inserted, the barbs hook onto the external thread of the oil bottle opening, the cylindrical part pushes open the bottle stopper that seals the oil bottle opening, and its upper end is inserted into the oil bottle.

[0016] The portion of the outer shell that mates with the piston support has a smaller diameter than the portion above it that mates with the oil bottle and cigarette holder, forming a platform that can mate with the barbs on the outer piston support; in the circumferential direction, the platform, except for the portion that mates with the barbs, forms axially recessed platforms on both sides.

[0017] The cigarette holder cover includes a cigarette holder on the left and an oil bottle cover on the right; the bottom end of the oil bottle cover protrudes axially downward to form a mating part that engages with the recessed platform and the platform surface; the dimension of the mating part to the inner bottom surface of the oil bottle cover is equivalent to the axial dimension of the oil bottle.

[0018] When the table surface engages with the barb above the annular portion, it limits the piston outer support to the first position inside the housing;

[0019] When the cigarette holder cap is inserted downwards, the barb above the annular part is pushed to bend towards the center, releasing the engagement with the platform until the bottom of the engagement part makes axial contact with the platform and engages. At this point, the piston support is in its second position.

[0020] The bottom cover protrudes upward with barbs corresponding to the hook opening of the piston outer support; when the piston support is in the first position, the bottom of the piston support and the bottom cover form an activation cavity; as the piston support moves from the first position to the second position, the activation cavity becomes smaller; when the piston support is in the second position, the barbs on the bottom cover engage with the hook opening of the piston outer support, and the activation cavity is completely compressed.

[0021] This invention innovatively features an activation cavity structure. When the e-liquid bottle is inserted, the e-liquid's own gravity and capillary action cause some of it to automatically enter the activation cavity for temporary storage. During the mouthpiece cap closing process, mechanical compression reduces the volume of the activation cavity, generating positive pressure to precisely force the temporarily stored e-liquid into the atomizer core assembly, achieving instant coil lubrication. This invention addresses three key issues: first, it solves the time-consuming process of traditional e-cigarettes requiring static lubrication, allowing for immediate vaping after assembly, significantly improving the user experience; second, the forced e-liquid supply through mechanical compression is more even and thorough than natural immersion, effectively preventing "dry burning" and "burnt coil" phenomena; and third, the activation cavity forms a buffer storage space, preventing excessive e-liquid seepage or leakage, enhancing product safety and reliability. The overall structure is compact and easy to operate, achieving a convenient "install and vape" experience. Attached Figure Description

[0033] The following embodiments are descriptions of specific implementations of the present invention. 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 invention. All equivalent transformations that can be obtained from the description of the embodiments of the present invention should be within the scope of protection of the present invention.

[0034] like Figures 1 to 10 As shown, the electronic cigarette cartridge of the present invention includes a shell 1, an atomizing core assembly 2, a piston support 3, a bottom cover 4, an oil bottle 5, and a mouthpiece cap 6. An atomizing channel 11 is provided on one side of the shell 1, within which the atomizing core assembly 2 is disposed. The other side is generally cylindrical. An axially movable piston support 3 is disposed within the cylindrical shape. An inverted oil bottle 5 can be inserted above the piston support 3; the mouthpiece cap 6 can be fitted over the oil bottle 5 and the top of the shell 1. The bottom cover 4 is provided at the bottom of the atomizing channel 11 and below the piston support 3, forming an activation cavity 7 that communicates with the atomizing core assembly between the piston support 3 and the bottom cover 4. When the oil bottle 5 is inverted on the piston support 3, the oil bottle 5 is open, and e-liquid enters the activation cavity 7 between the piston support 3 and the bottom cover 4; when the mouthpiece cap 6 is fitted, it pushes the oil bottle 5 and the piston support 3 downwards, compressing the activation cavity 7 until it is completely compressed.

[0035] Specifically, the oil bottle 5 is a conventional oil bottle 5; it consists of a bottle body 51 and a stopper 52. The top of the bottle body 51 forms a bottle mouth; a thread is formed on the outside of the bottle mouth; the stopper 52 is inserted into the bottle mouth to seal it. The stopper 52 can be moved into the bottle body under the action of external force to open the oil bottle 5.

[0036] like Figure 6The piston support 3 consists of a piston outer support 31 and a piston inner support 32 that cooperate with each other. The piston outer support 31 is composed of an annular portion 311, with two barbs 312 protruding upwards and symmetrically arranged in the circumferential direction at the top of the annular portion 311; the hook angles of the barbs 312 face outwards. The sidewall of the lower end of the annular portion 311 forms two hook openings 313 symmetrically arranged in the circumferential direction (correspondingly, the bottom cover 4 protrudes upwards and can hook into the hook openings), and the bottom end protrudes radially inwards to form a connecting ring 314. Correspondingly, the piston inner support 32 is composed of a cylindrical portion 321 that can be inserted into the oil bottle 5 from the opening of the oil bottle 5; the upper end of the cylindrical portion 321 forms an oil passage hole 322 that communicates with the inside and outside. The bottom end of the cylindrical portion 321 expands radially outwards to form a disc 323; a barb 324 is formed below the disc 323. The disc 323 is inserted into the annular part 311. The barb 324 below the disc 323 hooks onto the connecting ring 314 below the piston outer support 31. The piston outer support 31 and piston inner support 32 are fixed together by the cooperation of the connecting ring 314 and the disc 323.

[0037] like Figure 3 , 4 As shown in Figures 9 and 10, two barbs 325 protrude symmetrically in a circular direction above the disc 323; the hooks of the barbs 325 face inward. When the oil bottle 5 is inserted, the barbs 325 can hook onto the external thread at the mouth of the oil bottle, thus creating an axial linkage between the oil bottle 5 and the piston support 3. At this time, the cylindrical part 321 pushes open the bottle stopper 52 that seals the mouth of the oil bottle 5, and its upper end is inserted into the oil bottle 5; a channel from the inside of the oil bottle 5 to the cylindrical part 321 is formed through the oil passage 322.

[0038] like Figures 2 to 5 As shown in Figures 9 and 10, the portion of the outer shell 1 that mates with the piston support 3 has a smaller diameter than the portion above it that mates with the oil bottle 5 and the cigarette holder cap 6, forming a platform 12 that mates with the barbs on the piston outer support 31. The engagement of the platform 12 with the barbs 312 defines the first position of the piston outer support 31 within the outer shell 1. In the circumferential direction, apart from the portion that mates with the barbs 312, the platform 12 forms axially recessed platforms 13 on both sides; that is, the platform 12 extends axially upward between the two platforms 13.

[0039] like Figure 9 , 10The cigarette holder cover 6 includes a cigarette holder 61 on the left and an oil bottle cover 62 on the right. The bottom end of the oil bottle cover 62 protrudes axially downwards to form a mating part 63 that engages with the recessed platform 13 and the platform 12. The dimension of the mating part 63 to the inner bottom surface of the oil bottle cover 62 is approximately equal to the axial dimension of the oil bottle 5. When the cigarette holder cover 6 is inserted downwards over the oil bottle 5, the mating part 63 first contacts the top of the barb 312 of the annular part 311; at this time, the inner bottom of the oil bottle cover 62 contacts the bottom of the oil bottle 5. As the cigarette holder cover 6 continues to be pushed in, it pushes the barb 312 to bend towards the center, releasing its engagement with the platform 12. Continuing to push the cigarette holder cover 6 causes the piston support 3 and the oil bottle 5 to move downwards until the bottom of the mating part 63 axially contacts and engages with the recessed platform 13. At this time, the piston support 3 is in its second position.

[0040] When the piston support 3 is in the first position, the bottom of the piston support 3 and the bottom cover 4 form an activation cavity 7. At this time, the oil bottle 5 is pushed open by the cylindrical part 321; the e-liquid can enter the activation cavity 7 through the oil passage 322 and along the cylindrical part 321. When the piston support 3 is in the second position, the activation cavity 7 is completely compressed; the hook 313 of the piston outer support 311 engages with the corresponding barb 41 protruding upward from the bottom cover 4; the e-liquid in the oil bottle 5 enters directly into the atomizing core assembly 2 through the oil passage 322, the cylindrical part 321, the gap between the bottom cover 4 and the piston support 3, and the oil inlet on the atomizing core assembly 2.

[0041] As the piston support 3 moves from the first position to the second position, the activation cavity 7 shrinks, forcing the e-liquid within it into the atomizer core assembly 2. Inhalation is immediately possible once the mouthpiece cap 6 is properly installed (i.e., the piston support is pushed to the second position).

[0042] By engaging and disengaging the piston support 3 and the outer shell 1, and by moving them axially relative to each other, the axial distance between the bottom cover 4 and the piston support 3 is changed, thereby changing the volume of the activation cavity 7 formed by the piston support 3 and the bottom cover 4. This allows the e-liquid to be quickly pressed into the atomizing core assembly 2 before the mouthpiece cap 6 is fully assembled, thus achieving rapid core lubrication.

[0043] In the aforementioned structure, the piston support 3 and the outer shell 1 are unlocked by the mouthpiece cap 6; after unlocking, the piston support 3 and the oil bottle 5 are pushed together to achieve rapid wicking. Moreover, even if the mouthpiece cap 6 is assembled first, the piston support 3 for rapid wicking will not fail if the oil bottle 5 is not fully assembled. The cartridge with rapid wicking can only be activated after the oil bottle 5 is fully assembled.

[0044] The remaining parts of the electronic cigarette of this invention are unrelated to the implementation of the aforementioned scheme; they will not be described in detail here.
