[0022] In the description of this utility model, it should be understood that if there are descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationship, the orientation description may be based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0023] In the description of this utility model, if there is a description of quantity, "several" means one or more, "more than" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] like Figures 1 to 7As shown, this utility model discloses a controllable oil tank switch cartridge assembly, including an oil cup 1, an oil cup base 2, a mouthpiece 3, an atomizing core assembly, and a steel pipe connecting mechanism. The mouthpiece 3 has an air outlet, and a connecting pipe 31 is provided at the lower end of the air outlet. The steel pipe connecting mechanism includes a steel pipe 51 that is connected to the connecting pipe 31 and can rotate synchronously. The oil cup base 2 includes a sealing silicone seat 21 installed at the lower end of the oil cup 1. The sealing silicone seat 21 has an atomizing core mounting hole at its center. The side wall of the atomizing core mounting hole has two oppositely arranged oil inlet slots 211. The steel pipe 51 passes through the oil cup 1 and is fitted around the atomizing core assembly. The lower end of the steel pipe 51 and the lower end of the atomizing core assembly are both inserted into the atomizing core mounting hole. The lower end of the steel pipe 51 has an oil inlet hole 511 on each side, corresponding to the positions of the two oil inlet slots 211.

[0026] When the oil tank is closed after production and not in use or during transportation, the oil inlet 511 at the lower end of the steel pipe 51 is misaligned with the oil inlet slot 211 on the atomizer core mounting hole. At this time, the side wall of the atomizer core mounting hole will block the oil inlet of the steel pipe 51, and the oil in the oil cup 1 cannot enter the atomizer core assembly through the oil inlet 511. When it is necessary to open the oil tank, simply rotate the nozzle 3 to a certain angle. When the nozzle 3 rotates, it will drive the steel pipe 51 to rotate synchronously, so that the oil inlet 511 at the lower end of the steel pipe 51 rotates to the position of the oil inlet slot 211 on the atomizer core mounting hole. At this time, the oil inlet 511 connects the oil cup 1 and the atomizer core assembly, and the oil in the oil cup 1 will enter the atomizer core assembly through the oil inlet 511. After that, it can be used normally.

[0027] This invention has a simple structure. By rotating the nozzle 3, the channel between the oil tank and the atomizing core assembly can be controlled, effectively isolating the atomizing core assembly from the oil when not in use, and preventing oil leakage during transportation or when not in use.

[0028] In this utility model, the upper end of the oil cup 1 is provided with a suction nozzle connecting hole 11, and a sealing ring 52 is provided between the suction nozzle connecting hole 11 and the steel pipe 51 to ensure the sealing of the upper end of the oil cup 1 and prevent oil leakage.

[0029] In this utility model, the steel pipe connecting mechanism further includes a steel pipe cap 53 and a fixing ring 54. The lower end of the steel pipe cap 53 is fitted onto the upper end of the steel pipe 51 with an interference fit to achieve a fixed connection. The upper end of the steel pipe cap 53 is inserted into the connecting pipe 31 with an interference fit to achieve a fixed connection. The fixing ring 54 is fitted around the connecting pipe 31 to ensure the fixing effect between the connecting pipe 31 and the upper end of the steel pipe cap 53. The sealing ring 52 is located between the suction nozzle connecting hole 11 and the steel pipe cap 53 to ensure the sealing between the oil cup 1 and the steel pipe 51 and prevent oil leakage.

[0030] In this invention, the lower end of the suction nozzle 3 is provided with two rotation limiting blocks 32 located around the connecting pipe 31, and the upper end of the oil cup 1 is provided with a rotation limiting groove 13 adapted to the rotation limiting blocks 32 located around the suction nozzle connecting hole 11. This effectively limits the rotation of the suction nozzle 3, ensuring that the oil cup is in either an open or closed state and preventing excessive rotation.

[0031] In this utility model, the upper side of the oil cup 1 is also provided with an oil injection hole and an oil injection silicone plug 14 covering the oil injection hole. The oil injection hole is used for oil injection after assembly and is sealed by the oil injection silicone plug 14.

[0032] In this utility model, the atomizing core assembly includes a heating core 41 and an oil-absorbing cotton 42 sleeved around the heating core 41, with the oil-absorbing cotton 42 placed between the heating core 41 and the steel pipe 51.

[0033] In this invention, the oil cup base 2 further includes an oil cup bottom cover 22. The upper end of the oil cup bottom cover 22 has a receiving cavity. The lower end of the sealing silicone seat 21 is installed within the receiving cavity of the oil cup bottom cover 22. A snap-fit ​​mechanism is provided between the outer wall of the receiving cavity and the inner wall of the lower end of the oil cup. The middle part of the oil cup bottom cover 22 also has an air inlet communicating with the atomizing core assembly. The oil cup bottom cover 22 is used to fix the sealing silicone seat 21 and the oil cup 1.

[0034] In this utility model, the upper periphery of the air inlet is provided with two limiting top plates 222 that can be inserted into the atomizing core mounting hole and are arranged opposite to each other. The lower end of the steel pipe 51 is provided with slots 512 that are adapted to the two limiting top plates 222 respectively. The two slots 512 and the two oil inlets 511 are all located in the same direction of the steel pipe 51. The two limiting top plates 222 and the two oil inlet slots 211 are arranged in the same direction. When the oil tank is closed, the two limiting top plates 222 and the two slots 512 are misaligned. At this time, the sealing silicone seat 21 and the oil cup bottom cover 22 cannot be fully inserted into the oil cup 1. When the mouthpiece 3 is rotated, the mouthpiece 3 drives the steel tube 51 to rotate. At this time, the oil inlet 511 opens, and the two slots 512 at the lower end of the steel tube 51 are opposite to the two limiting top plates 222 on the oil cup bottom cover 22. In this way, the oil cup bottom cover 22 and the sealing silicone seat 21 can be moved into the oil cup 1 by pressing the oil cup bottom cover 22. As the space inside the oil cup 1 becomes smaller, the oil in the oil cup 1 will be instantly squeezed into the atomizing core assembly, thereby completing the rapid lubrication of the heating core 41, shortening the waiting time for the e-liquid to enter the atomizing core assembly, and meeting the user's needs in a timely manner.

[0035] In this invention, the latching mechanism includes multiple strip-shaped engaging grooves 12 disposed on the inner wall of the lower end of the oil cup 1 and multiple hooks 221 disposed on the outer wall of the oil cup bottom cover 22. By providing the strip-shaped engaging grooves 12, a preliminary engaging and fixing between the oil cup bottom cover 22 and the oil cup 1 can be achieved when not in use or during transportation. When in use, the oil cup bottom cover 22 can be directly pressed to allow the hooks 221 to slide within the strip-shaped engaging grooves 12.

[0036] This invention effectively prevents e-liquid leakage during manufacturing or transportation of electronic cigarettes. It is also simple and convenient to use, allowing e-liquid to quickly enter the atomizer core assembly for rapid user access. Furthermore, the structure is simple, easy to manufacture, and low in cost.

[0037] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
