Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic cigarettes, and in particular to a detachable electronic cigarette. BACKGROUND

[0002] In existing electronic cigarettes, some designs adopt a structure of stacking cartridges up and down, and the channel in the cartridge is usually designed as equal diameter. After the air enters the lower cartridge, it mixes with the smoke generated by the atomizing core to form primary smoke, and then flows into the upper cartridge to further mix with the smoke generated by the atomizing core of the upper cartridge, and finally forms the output smoke. This structure has high design and manufacturing simplicity, and to some extent meets the basic needs of the electronic cigarette market. However, with the improvement of users' requirements for the use experience of electronic cigarettes, the existing design gradually exposes some technical problems, especially in the uniformity of smoke mixing, the generation of condensate, and the consistency of taste.

[0003] In the prior art, the equal-diameter channel design does not fully consider the influence of volume change on mixing effect when the smoke flows between the upper and lower cartridges. Specifically, after the airflow enters the lower cartridge, the volume of the mixed gas increases significantly after mixing with the smoke generated by the atomizing core; when the primary smoke flows into the upper cartridge, the volume of the mixed gas is further expanded due to the smoke generated by the atomizing core of the upper cartridge. In the case where the flow rate of the gas remains unchanged, the rapid increase in volume will cause the gas pressure to rise, and the airflow will be in a turbulent state, making it difficult for the smoke to be further mixed uniformly. This uneven mixing directly affects the fullness of the smoke and the level of taste, making the user experience harsh.

[0004] In addition, due to the uneven mixing and the increase in gas pressure in the airflow, some of the atomized oil in the smoke is difficult to maintain a fully gaseous state, and small condensate droplets are easily formed on the channel wall or in the airflow. These condensate not only reduces the quality of the smoke and destroys the taste of the electronic cigarette, but also can accumulate in the channel, increasing the frequency and difficulty of cleaning the device, thereby affecting the long-term use performance of the product. CONTENT OF THE UTILITY MODEL

[0005] The purpose of the present application is to at least overcome one of the deficiencies of the prior art, and to provide a detachable electronic cigarette. The electronic cigarette uses a non-equal-diameter channel upper / lower cartridge structure design, which can more effectively address the problem of increasing volume of mixed gas and changes in gas pressure, and avoid the phenomenon of uneven mixing caused by excessive gas pressure. At the same time, through structural optimization and material selection, the new technology significantly reduces the generation of condensate, thereby ensuring the fullness of the smoke and the consistency of the taste.

[0006] To achieve the above object, the application discloses a detachable electronic cigarette, which comprises a body, a lower cartridge and an upper cartridge which are detachable and located in the body and relatively matched, wherein the upper cartridge has a through upper channel, and the lower cartridge has a through lower channel; each of the upper channel and the lower channel is provided with an atomizing core; the upper end of the lower channel directly / indirectly connects with the lower end of the upper channel to form a working channel for atomizing oil and mixing with air; the cross-sectional size of the upper channel is larger than that of the lower channel, so that the upper channel can bear greater flow capacity. Preferably, the cross-sectional area of the upper channel is 1.1 to 1.8 times of that of the lower channel.

[0007] Further, the upper cartridge and the lower cartridge are each provided with an oil reservoir for supplying oil to the atomizing core.

[0008] Further, the body is provided with a battery and a control board connected with the battery, and the upper cartridge and the lower cartridge are connected with the control board, so that the atomizing cores in the upper cartridge and the lower cartridge are powered and controlled by the control board.

[0009] As an optional technical solution, the upper channel and the lower channel are circular, the channel diameter of the lower channel is 2.0-2.3 mm, and the channel diameter of the upper channel is 2.6-3.0 mm.

[0010] As an optional technical solution, the body is further provided with a second working channel which is connected with the working channel, the second working channel is provided with an atomizing core and an oil reservoir for supplying oil to the atomizing core, and the atomizing core is connected with the control board and powered and controlled by the control board. Preferably, the working channel and the second working channel converge into a smoking channel having a mouthpiece at the upper end to form a connected relationship, so that the smoke of the working channel and the second working channel can be mixed and then output.

[0011] Compared with the prior art, the application has at least one of the following beneficial effects:

[0012] 1. Improved smoke mixing uniformity: by adopting a non-equal-diameter channel design, the cross-sectional size of the upper channel is larger than that of the lower channel, effectively solving the problem of uneven mixing caused by volume change and pressure rise during gas flow, thereby improving the mixing effect of the smoke, ensuring the uniformity of the smoke, and improving the smoking experience of the user.

[0013] 2. Reduced condensate generation: the technology optimizes the channel structure to significantly reduce the generation of condensate. The optimization of the design of the upper channel and the lower channel not only avoids the condensation phenomenon caused by excessive gas pressure, but also reduces the deposition of atomized oil on the channel wall, thereby maintaining the quality of the smoke and reducing the frequency and difficulty of equipment cleaning.

[0014] 3. Improve the fullness of smoke and the consistency of taste: The design of the upper channel being larger than the lower channel can better cope with the increase in volume and pressure changes of the mixed gas, thereby avoiding the influence of uneven mixing and condensate, ensuring the fullness of the smoke and the consistency of the taste, providing users with a higher quality smoking experience.

[0015] 4. Enhance the long-term use performance of the product: By reducing the accumulation and cleaning needs of condensate, this technology improves the long-term use performance of the electronic cigarette, reduces the maintenance frequency and difficulty, enhances the stability and durability of the equipment, and provides users with a more durable and reliable use experience. The above listed benefits are not exhaustive of all advantages. Other potential benefits and detailed technical implementations will be further disclosed in the examples or other description sections of this application. BRIEF DESCRIPTION OF DRAWINGS

Embodiments

[0023] The present embodiment discloses an exemplary structure of a detachable electronic cigarette, aiming to improve the uniformity of smoke mixing, the consistency of taste, and the reduction of condensate generation, optimize the user experience and improve the long-term performance of the device.

[0024] Referring to the drawings Figure 1 In particular, the basic structure of the electronic cigarette includes a body 1, an upper cartridge 2, and a lower cartridge 3. The upper cartridge 2 and the lower cartridge 3 each have a through upper channel 4 and a through lower channel 5, and each of the two channels has an atomizing core 7. The upper end of the lower cartridge 3 is connected to the lower end of the upper cartridge 2 through a connecting piece, thereby forming a through working channel 6. Air flows through the lower cartridge 3 and the upper channel 4 and the lower channel 5 of the upper cartridge 2, and mixes with the smoke generated by the atomizing core 7.

[0025] In the above structure, the cross-sectional size of the upper channel 4 is larger than that of the lower channel 4, thereby ensuring that the upper channel 4 can carry a larger flow capacity, avoiding air flow turbulence or uneven mixing caused by mismatched channel sizes.

[0026] Specifically, the cross-sectional area of the upper channel 4 is 1.1 to 1.8 times the cross-sectional area of the lower channel 5, ensuring the sufficiency and smoothness of smoke mixing.

[0027] It should be understood that in the present embodiment, the shape and size of the upper channel 4 and the lower channel 5 are crucial to the flow of smoke. In the preferred implementation, both the upper channel 4 and the lower channel 5 are designed as circles, and the diameter of the lower channel 5 is 2.0-2.3 mm, while the diameter of the upper channel 4 is 2.6-3.0 mm. Such design enables the smoke to avoid uneven mixing or poor flow due to volume and pressure mismatch when passing through the transition between the lower cartridge 2 and the upper cartridge 3. By reasonably designing the channel size and shape, it is ensured that the smoke can be fully mixed between the two channels, thereby improving the fullness and layering of the smoke.

[0028] In actual use, the smoke of the electronic cigarette is smoother and more uniform in taste. Thanks to the above design, the electronic cigarette can provide higher smoke quality when in use, and reduce the problem of poor user experience caused by unstable airflow or excessive condensate generation. At the same time, the user does not need to clean and maintain frequently after use, reducing the problem of equipment failure caused by condensate accumulation, thereby improving the long-term stability and reliability of the equipment.

[0029] To optimize the smoke mixing effect and reduce the generation of condensate due to uneven channel airflow pressure, the oil reservoir of the upper cartridge 2 and the lower cartridge 3 is designed to be able to stably supply oil to the corresponding atomizing core 7, for example, the oil reservoir is connected to the atomizing core 7 through an oil storage cotton core to supply oil. The role of the oil reservoir and the oil supply structure is the storage capacity and supply stability of the oil, ensuring that the atomizing core can obtain sufficient and uniform oil supply each time, thereby ensuring the stability of the atomization effect and the uniformity of the smoke quality.

[0030] It should be understood that the oil supply structure between the oil reservoir and the atomizing core and the flow mode of the oil are well known to those skilled in the art, and the present embodiment does not make further detailed description, because this part belongs to the known technology.

[0031] In addition, the working principle of the atomizing core is also well known to those skilled in the art, and will not be described in detail here. Briefly, the atomizing core heats the atomizing liquid by the power provided by the battery, so that the oil is rapidly vaporized to form smoke and mix with air.

[0032] In the present embodiment, the control board (not shown in the figure) controls the working state of the atomizing core 7 by precisely adjusting the output of the battery power, to ensure the amount of smoke and the atomization effect under different use conditions.

[0033] Specifically, the control board is connected to the atomizing core 7 in the upper cartridge 2 and the lower cartridge 3 respectively, and automatically adjusts the power output according to the user's inhalation demand, to ensure that the amount and quality of smoke can be maintained in the best state each time.

[0034] It should be understood that the working mechanism, adjustment mode and circuit connection mode of the control board are routine designs for those skilled in the art, and will not be described here.

[0035] In the embodiment, in order to improve the convenience and safety of the electronic cigarette, the battery is designed to be rechargeable. Specifically, a charging port is arranged in the body, through which the user can charge the battery. The design of the charging port is similar to the prior art, and common charging interfaces such as USB interfaces can be used.

[0036] In addition, in the implementation, in order to facilitate the user to understand the working state and battery capacity of the electronic cigarette, an indicator light or a display screen can also be arranged on the body of the electronic cigarette. The display screen or the indicator light can be used to indicate the battery capacity, the working state of the device and the fault prompt and other information. These designs are also routine practices for those skilled in the art when designing electronic cigarettes, and belong to the prior art, which will not be described in detail.

[0037] In addition, the connection structure and design of the body 1 and the upper cartridge 2 and the lower cartridge 3 also conform to the conventional structure design, and are well known to those skilled in the art. Through reasonable sealing design, it is ensured that the smoke will not leak, and the loss of oil can be effectively avoided, thereby improving the sealing and safety of the electronic cigarette. The upper cartridge 2 and the lower cartridge 3 can be detached and installed through magnetic adsorption, threaded connection or buckle structure, and the specific connection mode can be selected according to actual needs, which is a design method mastered by those skilled in the art.

[0038] In summary, the detachable electronic cigarette of the embodiment successfully solves the problems of uneven smoke mixing, condensate generation and taste consistency of the existing electronic cigarette by optimizing the channel design of the upper cartridge and the lower cartridge, the stable oil supply system of the atomizing core, the intelligent control of the control board and the battery charging design, meets the high requirements of users on the use experience of the electronic cigarette, and provides higher performance and lower maintenance cost. Embodiment

[0039] On the basis of Embodiment 1, the flexibility and adjustability of the electronic cigarette during use are enhanced in this embodiment, so that the user can flexibly select the taste combination according to personal preference to realize the diversification of taste. That is, the body is provided with a second working channel 8 in addition to the working channel 6. During work, the working channel 6 and the second working channel 8 output different smoke, which is finally mixed and output.

[0040] Specifically, the two cartridges in the working channel 6 can be configured to perform different functions. For example, the cartridges in the lower or upper oil reservoirs in the working channel 6 can be filled with oil with a specific flavor, such as menthol or other custom flavors, to provide additional flavor support to the smoke. The second working channel 8 can serve as the main smoke channel, with the built-in oil reservoir using regular or flavorless oil to produce the base smoke. When the two streams of smoke converge in the smoking channel, the right mix of flavors and regular smoke can be output simultaneously, enhancing the richness and depth of the taste. This design allows the electronic cigarette to not only meet the needs of single-flavor use, but also to provide a variety of flavor experiences through combinations.

[0041] This flexible design allows users to combine multiple flavors when using the electronic cigarette according to their individual needs. For example, in some scenarios, users can choose to use both channels for regular smoke to achieve a pure base flavor with higher fullness; in other scenarios, users can choose to use one channel in the working channel 6 for special flavor oil, while the second working channel 8 continues to be used as the main smoke channel, to achieve a mixed smoke output with a specific flavor. This flexible design significantly enhances the playability and user experience of the electronic cigarette, allowing it to meet basic needs while also catering to more personalized market needs.

[0042] In addition, this dual-channel flavor combination can further enhance the depth and uniqueness of the smoke. During smoking, users can experience the coordinated combination of flavor smoke and regular smoke, with the fullness of the base smoke and the freshness or unique flavor of the flavor smoke. This complex taste experience is difficult to achieve with existing single-channel electronic cigarettes, and is the difference between this embodiment and embodiment 1.

[0043] When in use, users can also adjust the flavor output of the cartridges in the working channel 6 by replacing different types of flavor oil, further enriching the use scenarios of the electronic cigarette. For example, in certain seasons or occasions, users can choose to add flavor oil that matches the festive atmosphere (such as menthol in winter or fruit flavor in summer), to achieve a smoking experience that is more in line with the use environment. This flexibility not only meets the user's demand for changing the taste of the smoke, but also significantly enhances the market appeal of the electronic cigarette.

[0044] In summary, this embodiment, through the design of the smoke channel, allows the electronic cigarette to achieve a variety of taste outputs through the flexible combination of main smoke and flavor smoke, thereby enhancing the flexibility and market competitiveness of the product. This design not only meets the user's demand for traditional smoke flavor, but also provides a more personalized and varied smoking experience, providing users with a higher quality of use.
