Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology. Background Technology

[0002] Currently, the flavor of e-liquid cartridges is generally achieved through a one-piece structure where flavor ingredients are pre-mixed with e-liquid and then directly packaged within the e-liquid reservoir. This technology has some limitations. For example, flavor ingredients are mostly volatile and easily oxidized active substances. After pre-mixing with e-liquid, they are susceptible to evaporation and loss during product storage and transportation due to environmental factors such as temperature fluctuations and light exposure. This leads to a decrease in e-liquid flavor concentration, flavor distortion, and a negative impact on the user experience. Therefore, there is room for improvement in existing flavored e-liquid cartridges. Utility Model Content

[0003] The technical problem solved by this disclosure is to provide a tobacco cartridge with a pre-built flavor pack and an electronic atomizing device having the tobacco cartridge.

[0004] The technical solution adopted by the utility model to solve its technical problem is: a cartridge with a built-in flavor pack, the cartridge including a shell and a base assembly, the shell forming an internal receiving space, the base assembly being installed at the bottom of the shell to seal the receiving space to form an oil storage tank, an atomizing component being installed in the oil storage tank; a flavor pack being placed in the oil storage tank; the shell having an oil injection hole communicating with the oil storage tank for injecting the electronic cigarette base liquid into the oil storage tank and fusing it with the flavor pack.

[0005] As described above, for e-cigarette cartridges with built-in flavor packets, the number of flavor packets placed in the oil storage compartment is one or more.

[0006] As described above, the e-liquid cartridge with a built-in flavor pack has a limiting member installed in the oil storage compartment. The limiting member is mounted above the base assembly, and the flavor pack is confined between the limiting member and the base assembly. The oil filling hole is located on the shell above the limiting member.

[0007] As described above, the cartridge with a built-in flavor pack has a top plate and a side plate extending downward along the edge of the top plate. A through hole is provided in the surface of the top plate, through which the lower end of the atomizing component passes to be mounted downward on the base assembly. A flow gap is formed between the through hole and the atomizing component to allow the base liquid of the electronic cigarette to flow downward to the flavor pack. The side plate is connected to the base assembly.

[0008] As described above, the e-cigarette cartridge with a built-in flavor pack includes an upper body and a lower body. The upper body is mounted on top of the lower body, and a surrounding side wall with a certain height extends upward along the edge of the upper body. The limiting member covers the upper body from top, and its side panel is fitted and connected to the surrounding side wall. The flavor pack is located between the limiting member and the upper body.

[0009] As described above, the e-liquid cartridge with a built-in flavor pack has a downwardly extending baffle at the edge of the through hole to stabilize the radial position of the flavor pack and prevent the flavor pack from blocking the oil inlet of the atomizing component.

[0010] As described above, for a cigarette cartridge with a built-in flavor pack, the inner wall of the enclosure sidewall is provided with a longitudinally extending and inwardly protruding limiting rib to limit the position of the flavor pack. The lower end of the limiting rib is flush with the bottom edge of the enclosure sidewall, and the upper end of the limiting rib is flush with the top edge of the enclosure sidewall.

[0011] An electronic atomizing device includes a main unit, and the electronic atomizing device further includes a cartridge as described in any of the preceding claims, the cartridge being assembled with the main unit.

[0012] The beneficial effects of this disclosure are as follows: The improved e-liquid cartridges have flavor packets pre-placed in the e-liquid reservoir, which are in a relatively sealed and independent environment before the e-cigarette base liquid is injected. This effectively isolates the cartridges from some external environmental factors and significantly reduces the evaporation and loss of flavor components. This helps to maintain the pure flavor of the original formula after mixing with the e-cigarette base liquid, avoids flavor decay or alteration, and significantly improves the consistency of the user experience.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] See appendix Figure 1-4The image shows a cartridge with a built-in flavor pack. The cartridge 1 includes a shell 2 and a base assembly 3. The shell 2 forms an internal receiving space. The base assembly 3 is installed at the bottom of the shell 2 to seal the receiving space to form an oil storage tank 4. An atomizing component 5 is installed in the oil storage tank 4. A flavor pack 6 is placed in the oil storage tank 4. The shell 2 has an oil injection hole 40 communicating with the oil storage tank 4 for injecting the electronic cigarette base liquid into the oil storage tank 4 and fusing it with the flavor pack 6.

[0026] The shell 2 is hollow inside to form a storage space. The bottom of the shell 2 is sealed by the base assembly 3, thus the storage space inside the shell 2 forms a sealed oil storage tank 4. The atomizing assembly 5 is installed in the oil storage tank 4. The upper part of the shell 2 forms a mouthpiece, which is connected downward to the atomizing assembly 5 to receive the smoke output by atomization.

[0027] Individual flavor packets 6 are pre-placed in the e-liquid storage tank 4 for storage and transportation. Users or distributors can then add the e-cigarette base liquid, typically composed of PG (propylene glycol) and VG (vegetable glycerin). The flavor packets 6 blend with the base liquid to form the e-liquid with the corresponding flavor. Pre-placing the flavor packets 6 independently in the storage tank 4 effectively prevents flavor components from evaporating, evaporating, or oxidizing, ensuring the original flavor formula is maintained after mixing with the base liquid, thus enhancing the user experience. Delaying the mixing of flavor components with the base liquid until just before use effectively avoids potential chemical reactions and stratification issues that may arise from long-term coexistence, ensuring the uniformity and atomization stability of the mixed e-liquid. Due to the improved stability of the flavor components, the overall shelf life of the cartridge 1 is extended, reducing product inventory losses and the risk of expiration.

[0028] Meanwhile, the production end can uniformly prepare e-liquid cartridges 1 and e-liquid storage tanks 4 with standardized flavor packs 6, which makes it easy to flexibly inject different types and concentrations of e-liquid bases according to the market, without the need for frequent overall adjustments to the production formula and cleaning equipment, thus simplifying the production process.

[0029] There is no limit to the number of Flavor Pack 6; it can be one or more. A single Flavor Pack can have a single flavor, or multiple flavors; it can also consist of multiple different flavor packs with distinct flavors. The blending of these different flavors can create new taste profiles. The outer layer can be made of gelatin, modified starch, or similar materials to encapsulate the corresponding flavor components. A larger number of Flavor Pack 6 typically requires more e-cigarette base liquid to dissolve completely. Users can refill the e-cigarette base liquid multiple times, which helps extend the user's experience of the flavored e-liquid and improves the overall experience.

[0030] In some embodiments, a limiting member 7 is disposed within the oil storage tank 4, and the limiting member 7 is mounted above the base assembly 3. The flavor pack 6 is confined between the limiting member 7 and the base assembly 3. The position of the filling hole 40 on the housing 2 is higher than the limiting member 7. The position of the flavor pack 6 is controlled by the limiting member 7 and the base assembly 3 to prevent it from moving freely within the oil storage tank 4, especially from moving to the filling hole 40, which would affect the injection of the e-cigarette base liquid. Therefore, the flavor pack 6 can be confined to a position below the filling hole 40. The filling hole 40 is equipped with a filling plug 41. The filling plug 41 is opened when e-cigarette base liquid needs to be injected, and closed after injection.

[0031] In some embodiments, the limiting member 7 has a top plate 70 and a side plate 71 extending downward along the edge of the top plate 70. A through hole 72 is formed in the surface of the top plate 70, through which the lower end of the atomizing component 5 passes to be mounted downward onto the base assembly 3. A flow gap is formed between the through hole 72 and the atomizing component 5 to allow the e-cigarette base liquid to flow downward toward the flavor pack 6. The side plate 71 is connected to the base assembly 3. The top plate 70 and the base assembly 3 cooperate to form a longitudinal constraint, preventing the flavor pack 6 from shifting vertically. Simultaneously, the side plate 71, while connected to the base assembly 3, restricts the radial movement of the flavor pack 6. The through hole 72 on the top plate 70 has a diameter larger than the radial dimension of the atomizing component 5, forming a flow gap between them. Thus, while allowing the atomizing component 5 to connect downward to the base assembly 3, the through hole 72 also allows for the normal flow of the e-cigarette base liquid, enabling it to contact and dissolve the flavor pack 6.

[0032] Specifically, the base assembly 3 includes an upper body 30 and a lower body 31. The upper body 30 is mounted above the lower body 31, and a surrounding side wall 301 with a certain height extends upward along the edge of the upper body 30. The limiting member 7 covers the upper body 30, and its side panel 71 is fitted and connected to the surrounding side wall 301. The flavor pack 6 is located between the limiting member 7 and the upper body 30.

[0033] The upper seat 30 and lower seat 31 can be fitted with the inner wall of the lower part of the shell 2 by means of tight fit or snap-fit ​​to ensure a stable connection with the shell 2 and seal the bottom of the shell 2. The edge of the upper seat 30 extends longitudinally upward to form a ring of side wall 301, which makes the middle of the upper seat 30 have a cavity structure, forming the lower part of the oil storage tank 4. The limiting member 7 is placed in the cavity structure and is covered by the limiting member 7. The side plate 71 of the limiting member 7 is tightly fitted to the outer surface of the side wall 301 of the upper seat 30. The connection between the two can be made by means of tight fit or snap-fit ​​to ensure the stability of the connection.

[0034] In some embodiments, the edge of the through hole 72 is provided with a downwardly extending baffle 73 to stabilize the radial position of the flavor pack 6, so as to prevent the flavor pack 6 from blocking the oil inlet of the atomizing assembly 5. The baffle 73 can prevent the flavor pack 6 from moving radially toward the atomizing assembly 5, so as to avoid blocking the oil inlet of the atomizing assembly 5 and affecting the atomization of e-liquid.

[0035] Furthermore, the inner wall of the enclosure side wall 301 is provided with a longitudinally extending and inwardly protruding limiting rib 302 to limit the position of the flavor pack 6. The lower end of the limiting rib 302 is flush with the bottom edge of the enclosure side wall 301, and the upper end of the limiting rib 302 is flush with the top edge of the enclosure side wall 301.

[0036] The space between the limiting component 7 and the base assembly 3 has a certain height. The initial height of the flavor pack 6 is roughly the same as the height of the space between the limiting component 7 and the base assembly 3. The baffle 73 on the limiting component 7 effectively provides radial restraint. As the flavor pack 6 gradually dissolves into the e-cigarette base liquid, its volume shrinks, typically settling near the bottom of the oil reservoir 4. The restraining rib 302, extending upwards from the side wall 301 of the upper body 30, provides radial restraint for the flavor pack 6 at multiple height positions, preventing it from approaching the oil inlet of the atomizing component 5. Thus, the baffle 73 of the limiting component 7 and the restraining rib 302 of the upper body 30 work together to radially restrain the flavor pack 6 from its initial state to its final fusion state, ensuring normal e-liquid atomization.

[0037] See appendix Figure 5 An electronic atomizing device 9 is provided, comprising a main unit, the electronic atomizing device 9 further comprising a cartridge 1 as described in any of the preceding claims, the cartridge 1 being assembled with the main unit.

[0038] In summary, the technology of pre-packing flavor packets within the e-liquid cartridge is an optimization and upgrade of the traditional pre-mixing method for e-liquid flavor components. Its core is to encapsulate the flavor components and pre-place them within the e-liquid cartridge's reservoir. After the e-cigarette base liquid is added, the flavor packets gradually dissolve, achieving flavor fusion. This solution effectively isolates the flavor components from environmental factors, avoiding oxidation and stratification issues caused by pre-mixing, ensuring e-liquid homogeneity and flavor stability. Simultaneously, it simplifies the production process, improves the flexibility of adapting to different e-liquid bases and flavors, extends product shelf life, and significantly improves the user experience.
