[0031] The oil filling pipe 5 is inserted into the connecting passage 44, and an oil filling hole 53 is formed on the wall of the oil filling pipe 5. The oil filling pipe 5 has a first end 51 and a second end 52 which are arranged opposite to each other, wherein the first end 51 is arranged toward the installation chamber 41, and the second end 52 is arranged toward the oil storage chamber 42. The first end 51 is an open end communicating with the oil filling hole 53, and the second end 52 is a closed end. A clamping portion 54 is convexly formed on the outer peripheral wall of the oil filling pipe 5;

[0032] The oil filling pipe 5 is capable of moving in the connecting channel 44 to switch from the sealing position to the oil filling position. When the oil filling pipe 5 is located at the sealing position, the oil filling pipe 5 is clamped with the connecting channel 44 through the clamping portion 54, and the oil filling hole 53 is located outside the oil storage chamber 42, and the oil filling hole 53 is not connected to the oil storage chamber 42; when the oil filling pipe 5 is located at the oil filling position, the oil filling hole 53 is located in the oil storage chamber 42, and the oil storage chamber 42 is connected with the first end 51 of the oil filling pipe 5 through the oil filling hole 53.

[0033] The design of the built-in oil storage chamber 42 and the oil filling tube 5 provides a more efficient and hygienic oil filling method. The user can simply control the opening and closing of the oil storage chamber 42 by moving the oil filling tube 5, thereby avoiding the complexity of manually inserting the oil bottle upside down. In addition, the sealing position design of the oil filling tube 5 ensures that the oil in the oil storage chamber 42 will not leak when not in use, further reducing the waste of oil and the loss of aroma. The clamping portion 54 can form a clamping connection with the connecting channel 44 to prevent the oil filling tube 5 from falling into the oil storage chamber 42 during storage and transportation.

[0034] In some embodiments of the present application, an oil pipe seal 6 is also included, which is sleeved on the oil filling pipe 5 and located at the outer periphery of the clamping portion 54; this design increases the sealing performance of the oil filling system, ensuring that when the oil filling pipe 5 is in a sealed position, the tobacco oil will not leak out from the joint between the oil filling pipe 5 and the connecting channel 44. This helps to keep the inside of the electronic cigarette clean, reduce the maintenance frequency, and extend the service life of the electronic cigarette.

[0035] In some embodiments of the present application, the clamping portion 54 is disposed around the outer peripheral wall of the oil filling pipe 5, which can enhance the structural stability between the oil filling pipe 5 and the connecting channel 44. This makes the oil filling pipe 5 more secure during transportation or storage, and reduces the risk of falling off or shifting due to vibration or misoperation.

[0036] In some embodiments of the present application, the clamping portion 54 is located between the oil filling hole 53 and the second end 52. That is, the oil filling hole 53 is located above the clamping portion 54 and there is a certain distance between the oil filling hole 53 and the clamping portion 54. When the oil filling tube 5 is in the sealing position, the oil can be effectively prevented from flowing back from the oil storage chamber 42 to the oil filling tube 5.

[0037] In some embodiments of the present application, the oil filling tube 5 is provided with a plurality of the oil filling holes 53, and the oil filling holes 53 are arranged at equal intervals along the circumference of the oil filling tube 5. The equal interval arrangement of the plurality of oil filling holes 53 ensures that the smoke oil can flow evenly from the oil filling tube 5 into the oil storage chamber 42, avoiding the problem of poor or uneven flow of the smoke oil that may be caused by a single oil filling hole 53. The plurality of oil filling holes 53 can also work simultaneously, significantly improving the speed and efficiency of the smoke oil injection.

[0038] In some embodiments of the present application, an oil storage cotton 7 is further included, and the oil storage cotton 7 is arranged in the oil storage chamber 42, and the oil storage cotton 7 is provided with a cavity 71 for accommodating the oil filling tube, and the cavity 71 is connected to the connecting channel 44. The material of the oil storage cotton 7 generally has good oil absorption and oil retention, and it can absorb and retain more smoke oil, effectively improve the smoke oil absorption and transmission efficiency, reduce the volatilization of smoke oil, prolong the use time of the electronic cigarette, and reduce the number of frequent oil fillings by users.

[0039] In some embodiments of the present application, when the oil filling tube 5 is located at the oil filling position, the first end 51 of the oil filling tube 5 protrudes from the connecting channel 44 and is located in the installation chamber 41. The first end 51 of the oil filling tube 5 protrudes from the connecting channel 44 and is located in the installation chamber 41, which means that the user can directly align the opening of the oil filling bottle 1 with the first end 51 of the oil filling tube 5 when filling oil, without complicated alignment operations, simplifying the oil filling process. In addition, when in the oil filling position, the oil filling tube 5 can be in close contact with the sealing silicone of the oil filling bottle 1, and the sealing silicone is pushed open by the oil filling tube 5 to form an effective seal, thereby reducing the leakage of the e-liquid during the oil filling process.

[0040] Reference Figure 5 and Figure 6 In some embodiments of the present application, an oil filling bottle 1 is further included; the oil filling bottle 1 is provided with a chamber 13 for accommodating tobacco oil and a bottle mouth 11 connected to the chamber 13, the bottle mouth 11 is sleeved with an oil filling seal 3, and the oil filling seal 3 is provided with a petal-shaped opening that can be opened under the action of an external force; when the oil filling bottle 1 is installed in the installation chamber 41, the oil filling pipe 5 is located at the oil filling position, and the first end 51 of the oil filling pipe 5 is inserted into the bottle mouth 11 through the petal-shaped opening; the oil storage chamber 42, the oil filling pipe 5, the bottle mouth 11 and the chamber 13 are connected in sequence.

[0041] By designing an integrated connection between the oil filling bottle 1 and the electronic cigarette, the user can simply install the oil filling bottle 1 to complete the oil filling process without additional manual operation, which greatly improves the convenience of oil filling. The petal-shaped opening design allows the oil filling bottle 1 to remain sealed when not in use to prevent oil leakage. In conjunction with the oil filling tube 5, the oil filling tube 5 can not only push open the oil filling seal 3, but also maintain a sealed state after the oil filling is completed to prevent oil backflow or leakage, thereby improving the overall sealing performance.

[0042] In some embodiments of the present application, a step portion 111 is convexly provided on the inner wall of the bottle mouth 11 for abutting against the oil filling tube 5. The step portion 111 on the inner wall of the bottle mouth 11 is tightly abutted against the oil filling tube 5, thereby enhancing the connection stability between the oil filling tube 5 and the oil filling bottle 1, and enabling the oil filling tube 5 to be accurately aligned when inserted into the bottle mouth 11. In use, the oil filling tube 5 can be pushed into the oil storage chamber 42 by the abutment of the step portion 111, forming a connection between the oil storage chamber 42 and the chamber 13.

[0043] In some embodiments of the present application, a mounting groove 411 adapted to the bottle mouth 11 is provided on one side of the mounting chamber 41 close to the connecting passage. In a specific embodiment of the present application, the mounting groove 411 is located at the bottom of the mounting chamber 41. The mounting groove 411 can provide precise alignment guidance and clear insertion depth indication for the oil filling bottle 1, so that the user can easily determine whether the oil filling bottle 1 has been correctly installed when filling oil, thereby simplifying the operation process.

[0044] In the specific embodiment of the present application: the connection channel 44 between the oil storage chamber 42 and the installation chamber 41 is sealed by the oil filling pipe 5 installed with the oil pipe seal 6, wherein the oil filling pipe 5 can be a stainless steel pipe. During assembly, the entire electronic cigarette rod is assembled first, and the oil storage chamber 42 has a connection channel 44. The oil filling pipe 5 is covered with the oil pipe seal 6 and installed in the connection channel 44 to seal it, so as to prevent the oil in the oil storage cotton 7 from leaking out and the fragrance from escaping.

[0045] During the manufacturing process, a bulging process is used to process a convex ring on the stainless steel tube to form a clamping portion 54 of the oil filling tube 5, and the oil pipe seal 6 and the connecting channel 44 are put on to achieve clamping sealing, so as to ensure that the oil filling tube 5 is not easy to fall off or move during logistics transportation. When installing the oil filling bottle 1, the oil filling tube 5 is used to push open the petal silicone of the oil filling bottle 1 to start oiling.

[0046] Specifically, after the user unscrews the bottle cap of the oil filling bottle 1, the user inserts the entire oil filling bottle 1 upside down into the electronic cigarette rod. After the bottle mouth 11 of the oil filling bottle 1 contacts the oil filling tube 5, the oil filling tube 5 is pushed to move in the direction of the oil storage cotton 7, and the oil filling tube 5 is moved to the oil filling position. At the same time, the oil filling tube 5 pushes open the petal-shaped opening of the oil filling seal 3 at the bottle mouth 11, and the tobacco oil flows from the chamber 13 through the oil filling tube 5 into the oil storage cotton 7, thereby achieving the purpose of filling the tobacco rod with oil.
