[0002] As a tobacco alternative, e-cigarettes are gaining increasing market penetration. One of the core components of e-cigarettes is the cartridge, which stores e-liquid and atomizes it using an atomizer for user inhalation. Currently, in most e-cigarette cartridges, the composition and flavor of the e-liquid are fixed at the time of manufacture. Users can only choose from a limited number of preset flavors and cannot adjust them according to personal preference after purchase. Utility Model Content

[0003] To address the shortcomings of related technologies, one aspect of this utility model proposes a cigarette cartridge structure, which includes: The shell and the base are provided. The shell has a connection port and the base is inserted into the connection port. The base and the shell together form a receiving cavity. The shell has a top wall that is arranged opposite to the base. A suction nozzle is provided on the side of the top wall facing away from the base. The top wall also has an injection hole arranged adjacent to the suction nozzle. A sealing cap is inserted into the injection hole. The atomizer is located inside the receiving cavity. One end of the atomizer is connected to the mouthpiece, and the other end of the atomizer is inserted into the base. Oil-storing cotton fills the receiving cavity and wraps the atomizer. The oil-storing cotton has an injection channel that communicates with the injection hole. The injection channel and the injection hole are arranged coaxially. The oil-retaining cotton is pre-wetted with base liquid, and the injection hole is used to inject fragrance liquid.

[0004] Furthermore, a mounting groove is formed on the side of the base facing the top wall, and the atomizer includes: The exhaust pipe has one end connected to the mouthpiece; The atomizing core has one end connected to the other end of the smoke outlet tube, and the other end of the atomizing core is inserted into the bottom wall of the mounting slot. Oil storage cotton includes: The first oil storage section is connected to the smoke outlet pipe, and the injection channel is opened in the first oil storage section; The second oil reservoir is fitted onto the atomizer core and contacts the first oil reservoir.

[0007] Another aspect of this utility model provides an electronic cigarette, which includes a cartridge structure as described above and a power supply structure for the cartridge structure.

[0008] Compared with related technologies, the cartridge structure of this utility model features a separate "base liquid-flavor liquid" design. This allows users to inject the flavor liquid through the injection hole according to their preference after receiving the cartridge. The flavor liquid is absorbed by the oil-retaining cotton as it flows within the injection channel and blends with the base liquid. Therefore, the aerosol generated by the atomization of this utility model cartridge has the user's preferred flavor. In summary, the cartridge structure using this utility model allows users to adjust the flavor of the cartridge according to their own preferences. Attached Figure Description

If the specific posture changes, the directional indicator will also change accordingly.

[0014] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0015] Furthermore, the descriptions involving "first," "second," etc., in the embodiments of this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0016] To address the technical deficiencies in related technologies, this embodiment provides an electronic cigarette, such as... Figure 1 As shown, the electronic cigarette includes a cartridge structure 100 for atomizing e-liquid to generate an aerosol, and a cigarette rod structure 200 for supplying power to the cartridge structure 100.

[0017] Continue to refer to Figure 2 As shown, in this embodiment, the cartridge structure 100 includes a shell 110 and a base 120. The shell 110 has a connection port 111, and the base 120 is inserted into the connection port 111, so that the base 120 and the shell 110 enclose a receiving cavity. The shell 110 has a top wall 112 arranged opposite to the base 120. A mouthpiece 113 is provided on the side of the top wall 112 facing away from the base 120. The top wall 112 also has an injection hole 114 arranged adjacent to the mouthpiece 113, and a sealing cap 115 is inserted into the injection hole 114.

[0018] Continue to refer to Figure 2 As shown, an atomizer 130 is disposed within the receiving cavity. One end of the atomizer 130 is connected to the mouthpiece 113, and the other end of the atomizer 130 is inserted into the base 120. The receiving cavity is also filled with oil-retaining cotton 140, which wraps around the atomizer 130. The oil-retaining cotton 140 has an injection channel 1411 that communicates with the injection hole 114, and the injection channel 1411 is coaxially arranged with the injection hole 114.

[0019] In this embodiment, the oil-retaining cotton 140 is pre-wetted with a base liquid, which is formed by mixing PG (Propylene Glycol) and VG (Vegetable Glycerin) in a certain proportion. This base liquid has no flavor.

[0020] When a user uses the cartridge structure 100 of this embodiment, they inject flavoring liquid through the injection hole 114 according to their preference. As the flavoring liquid flows within the injection channel 1411, it is absorbed by the oil-retaining cotton 140 and blends with the base liquid, thus the aerosol generated by the cartridge structure 100 of this embodiment has the user's preferred flavor.

[0021] Furthermore, continue to refer to Figure 2 As shown, in this embodiment, a mounting groove 121 is formed on the side of the base 120 facing the top wall 112. The atomizer 130 includes a smoke outlet tube 131 and an atomizing core 132. One end of the smoke outlet tube 131 is connected to the mouthpiece 113, and one end of the atomizing core 132 is connected to the other end of the smoke outlet tube 131, with the other end of the atomizing core 132 inserted into the bottom wall of the mounting groove 121. The oil reservoir 140 includes a first oil reservoir 141 and a second oil reservoir 142. The first oil reservoir 141 is fitted onto the smoke outlet tube 131, and an injection channel 1411 is opened in the first oil reservoir 141. The second oil reservoir 142 is fitted onto the atomizing core 132 and contacts the first oil reservoir 141, thereby allowing the flavoring liquid that has penetrated the first oil reservoir 141 to diffuse into the second oil reservoir 142 and enter the atomizing core 132.

[0022] Optionally, in order to increase the diffusion rate of the fragrance liquid, a portion of the second oil storage section 142 blocks the injection channel 1411, so that some of the fragrance liquid that is not absorbed by the first oil storage section 141 directly reaches the second oil storage section 142 under the action of gravity.

[0023] For example, the cartridge structure 100 of this embodiment may also include an oil guide tube 150, which is inserted into the injection channel 1411. The tube wall of the oil guide tube 150 is provided with multiple oil outlet holes, so that the flavor liquid can be evenly seeped out during the flow process, rather than concentrated in a certain area of ​​the first oil storage part 141. This ensures that the flavor liquid is absorbed more efficiently by the first oil storage part 141 and reduces the risk of local oversaturation or loss.

[0024] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
