It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may include, for example, a fixed connection, an integral connection, or a detachable connection; may be communication within two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art can understand the specific meaning of the above terms in the present invention in specific situations.

The schematic diagram of the preferred embodiment of the cartridge provided by the present scheme is shown in fig. 1 and fig. 2, the cartridge 1 is provided with a flue 10 and an inner cavity 12, the flue 10 is communicated with the inner cavity 12, and the flue gas atomized by the atomizer flows out from the inner cavity 12 along the flue 10. And a backflow groove 11 is formed in the inner wall of the flue 10 and communicated with the inner cavity 12. The backflow groove 11 can prevent large liquid drops from adhering to the inner wall of the flue 10 and can guide the liquid drops to flow back into the inner cavity 12, thereby preventing liquid leakage.

The backflow grooves 11 are provided with a plurality of grooves, four grooves are provided in the embodiment, and the four backflow grooves 11 are uniformly distributed along the circumferential direction of the flue 10, so that the area of the inner wall of the flue 10 where liquid drops can adhere is small enough, and the liquid drops are further prevented from being accumulated. The return grooves 11 extend in the axial direction of the flue 10, and contribute to smoother flow of the liquid droplets back into the interior of the inner chamber 12.

The existing common cigarette cartridge of the electronic cigarette is usually directly exposed outside, so that the surface of the cigarette cartridge needs to be processed when the appearance design is carried out, but the appearance design on the surface of the cigarette cartridge is difficult in process, and the internal structure of the cigarette cartridge is not influenced, so that the design of a complex appearance is difficult. Moreover, as the cartridges are often replaced, the complex appearance of the cartridge surface design is not a good undertaking. In view of this, as shown in fig. 3 to 10, the present disclosure further provides an embodiment of an electronic cigarette. The electron cigarette has included above-mentioned cartridge 1, shell subassembly 2 and base subassembly 3, shell subassembly 2 with the detachable connection of base subassembly 3, cartridge 1 set up in shell subassembly 2 inside and with base subassembly 3 is connected. The housing assembly 2 and the base assembly 3 may be connected by a screw or a snap. Since the cartridge 1 is arranged inside the housing component 2, the outer surface of the cartridge 1 can be simplified as much as possible, while a correspondingly more complex design can be designed on the surface of the housing component 2. Designing the appearance on the outer surface of the housing assembly 2 not only simplifies the process and enables more complex designs to be achieved, but also helps to save costs since the housing assembly 2 does not need to be replaced during use, as compared to designing the appearance on the surface of the cartridge 1.

In view of the fact that the existing electronic cigarette is mostly provided with the charging port 31, in order to further beautify the appearance, as shown in fig. 4 to 6, an air inlet groove 32 is arranged on the inner wall of the charging port 31 of the base assembly 3, and the air inlet groove 32 is communicated with the inside of the base assembly 3, so that the normal operation of the atomizer is ensured. Air flows into the interior of the base assembly 3 in the direction of the arrows shown in figure 6, ensuring smooth ventilation of the cartridge 1. This kind of scheme need not to ventilate in shell subassembly 2 or base subassembly 3 surface trompil, has avoided the trompil to influence the outward appearance, further helps promoting the outward appearance effect.

The outer housing component 2 comprises an outer housing 20 and an inner housing 21, the inner housing 21 being fixedly connected within the outer housing 20, and the cartridge being received within the inner housing 21. The base component 3 is provided with a connecting section 33, the outer surface of the connecting section is provided with an external thread, the inner wall surface of the inner shell 21 is provided with an internal thread 212 matched with the external thread, and meanwhile, the inner shell 21 is in threaded connection with the base component 3. In this embodiment, the outer casing 20 and the inner casing 21 are two independent components, so that the connection structure between the outer casing 2 and the base assembly 3 can be designed on the inner casing 21 and the appearance can be designed on the outer surface of the outer casing 20, and then the outer casing 20 and the inner casing 21 are fixedly connected, which helps to further simplify the process.

Specifically, a convex mouth 23 is provided on the inner wall of the housing 20, and the convex mouth extends towards the inside of the housing 20 along the axial direction of the housing 20. The surface of the inner shell 21 is provided with a connecting hole 211 matched with the convex mouth 23, and the convex mouth 23 is inserted into the connecting hole 211 and fixedly connected with the connecting hole 211 in an interference fit manner. The outer shell 20 is provided with a flue 22, and the flue 22 penetrates through the convex nozzle 23. The convex mouth 23 can be fixedly connected with the outer shell 20 and the inner shell 21 after being in interference fit with the connecting hole 211, and the convex mouth 23 can be inserted into the inner shell 21 and close to a smoke cartridge, so that the smoke outlet channel 22 is communicated with the smoke channel 10, and smoke can flow out conveniently.

The convex mouth 23 comprises an extending section 231 and a clamping section 232, and the outer diameter of the clamping section 232 is larger than that of the extending section 231. The extending section 231 is inserted into the inner shell 21, and the clamping section 232 is connected with the inner shell 21 in an interference fit manner. The protruding section 231 is inserted to communicate with the flue 10. Of course, the connection mode between the outer shell 20 and the inner shell 21 is not limited to this, and meanwhile, the procedures such as welding and the like may be added on the basis to ensure the fixed connection between the outer shell 20 and the inner shell 21.

In summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
