AI Technical Summary
In existing pod-based e-cigarettes, the e-liquid film is difficult to flow effectively into the e-liquid storage space, resulting in uneven e-liquid replenishment and unstable oil pressure, which can easily lead to oil leakage.
A pod structure was designed, in which the top of the activation column is pointed and has radial steps, which are used to pierce and push open the aluminum film, allowing the e-liquid to enter the oil storage cotton through the flow channel, ensuring uniform dispersion of the e-liquid and controlling the flow rate.
It achieves even replenishment of e-liquid to the reservoir cotton, avoids leakage, ensures the balance of e-liquid in the reservoir, and improves the user experience.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and specifically to a cartridge activation and cartridge oil filling structure for a replaceable electronic cigarette. Background Technology
[0002] For cartridge-based e-cigarettes, the cartridge opening is typically sealed with an aluminum foil. During cartridge assembly, the aluminum foil is punctured by a mating structure, allowing e-liquid to enter the reservoir. Due to the relatively flexible nature of the aluminum foil, even when punctured, the e-liquid is difficult to flow into the reservoir. Utility Model Content
[0003] The technical problem solved by this utility model is to provide an oil cartridge activation and oil inlet structure for a replaceable e-cigarette; after the oil bottle is assembled, it can ensure that the e-liquid flows into the oil storage cotton space.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:
[0005] The structure includes a fuel cartridge and a fuel tank. The top of the fuel cartridge forms a mouthpiece, and a smoke channel forms along the central axis. An oil storage chamber is formed along the outer wall of the smoke channel and the outer shell of the fuel cartridge. An aluminum film is sealed below the oil storage chamber. The top of the fuel tank is provided with an upward-facing, pointed activation column corresponding to the oil storage chamber. A radial step is connected to the activation column. An e-liquid flow channel is provided between the activation column and the inner wall of the fuel tank.
[0006] The activation column is positioned near the outer side of the smoke channel wall.
[0007] The activation columns are arranged continuously around the outer side of the smoke channel wall or in several rows along the circumference.
[0008] The activation columns are arranged continuously around the circumference or in multiple rows along the circumference.
[0009] The top surface of the step is slightly lower than the top of the activation column.
[0010] The steps are flat and are arranged in a circumferential gear pattern between the activation column and the inner wall of the oil tank.
[0011] In this invention, the aluminum film of the sealed e-liquid cartridge is pierced by the sharp corner of the activation post. The aluminum film tears upwards along the bevel of the sharp corner. When the pierced part reaches the step section, the platform pushes the aluminum film upwards, opening the cartridge and activating it. After activation, the e-liquid inside the cartridge flows through the piercing hole to replenish the side of the reservoir cotton. The reservoir cotton has vertical ribs, so the e-liquid is supplied from the side, making the speed of e-liquid entry related to the density of the reservoir cotton, thus achieving controllability. Moreover, the e-liquid is more evenly distributed throughout the reservoir cotton for the consumer to use. Guiding the e-liquid to the side of the reservoir cotton controls the amount of e-liquid entering the reservoir based on the negative pressure during the user's inhalation, maximizing the balance of e-liquid in the tank and preventing leakage due to excessive oil pressure.

[0016] The following embodiments are descriptions of specific implementations of the present utility model. 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 utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.
[0017] like Figure 1-3 As shown, the cartridge activation and cartridge oil filling structure of the present invention for the replaceable electronic cigarette includes a cartridge 1 and an oil tank 2. A mouthpiece 11 is formed on the top of the cartridge 1, a smoke channel 12 is formed in the central axis, and an oil storage cavity 15 is formed along the outer side of the smoke channel wall 13 and the cartridge shell 14. An aluminum film 16 is sealed below the oil storage cavity 15.
[0018] The top of the oil tank 2, corresponding to the oil storage cavity, is equipped with an upward-facing, pointed activation column 21. The activation column is located near the outer side of the smoke channel wall 13; the activation column 21 can be arranged continuously in a circle or several columns can be arranged along the circumference.
[0019] The activation column 21 is connected to radial steps 22; the steps 22 are vertical flat plates; they are arranged in a gear-like pattern along the circumference between the activation column 21 and the inner wall of the oil tank 2. The top surface of the steps 22 is slightly lower than the top of the activation column 21.
[0020] An oil flow channel 23 is provided between the activation column 21 and the inner wall of the oil tank 2.
[0021] like Figure 3 , Figure 1 As shown, during the transition from a separated state to an assembled state between the fuel cartridge 1 and the fuel tank 2, the aluminum film 16 is pierced by the sharp corner of the activation column 21, and the aluminum film 16 tears upward along the bevel of the sharp corner; when the pierced part reaches the step 22, the top surface of the step 22 pushes the aluminum film 16 upward as a whole, thus opening the aluminum film 16 and activating the fuel cartridge 1. The e-liquid inside the fuel cartridge 1 will then flow through the piercing hole to replenish the side of the oil reservoir 3.
[0022] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. The remaining parts are not related to the implementation of the above technical solution, nor are they limited to those shown in the figure; they will not be described in detail here.
