[0033] The concept, specific structure and generated technical effects of the utility model will be described clearly and completely in combination with embodiments and drawings, so as to fully understand the purpose, features and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all embodiments, based on the embodiments of the utility model, other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model. In addition, all the coupling / connection relations involved in the patent are not single component direct connection, but can be composed of better coupling structure by adding or reducing coupling auxiliary parts according to the specific implementation situation. The various technical features in the utility model creation can be interactively combined without mutual contradiction and conflict.

[0034] Referring to Figure 1 , 2 The double-group atomization electronic cigarette of the utility model includes shell 10, the shell 10 has first accommodating cavity 11 and second accommodating cavity 12, and first atomization assembly 20 and second atomization assembly 30 are arranged in the shell 10, wherein the second atomization assembly 30 is detachably arranged in the second accommodating cavity 12. In addition, it also includes battery 70, the battery 70 is electrically connected with the first atomization assembly 20 and the second atomization assembly 30, and provides the electric energy required for the work of two atomization assemblies.

[0035] The first atomization assembly 20 and the second atomization assembly 30 each include an atomization core and a liquid storage cavity, the atomization core is arranged in the liquid storage cavity, absorbs the atomization liquid in the liquid storage cavity through the atomization core, and forms an aerosol after being heated by electricity. The first atomization assembly 20 has a first liquid storage cavity 21, and the second atomization assembly 30 has a second liquid storage cavity 32. The first liquid storage cavity 21 and the second liquid storage cavity 32 are respectively used to contain different kinds of atomization liquid. In this way, by combining different atomization liquids, the user can choose to use one kind of atomization liquid alone or use two kinds of atomization liquid at the same time according to personal preference, so as to obtain a richer taste experience. For example, the first atomization assembly 20 can be used to contain a conventional atomization liquid to provide a basic smoke, and the second atomization assembly 30 can be used to contain an atomization liquid with an ice feeling. When the two kinds of atomization liquid are used at the same time, the basic smoke can be added with a cool taste. This combination can allow the user to freely adjust the coolness according to personal preference, that is, the basic smoke can be used alone, or the smoke with a cool feeling can be obtained by starting the second atomization assembly 30, so as to realize a more personalized smoking experience.

[0036] Specifically, referring to Figure 2 The second atomization assembly 30 is fixed in the second accommodating cavity 12 through a bottom cover 40, and the bottom cover 40 is detachably connected to the end of the shell 10. It can be understood that by detaching the bottom cover 40, the detachability of the second atomization assembly 30 can be realized. In some embodiments, the capacity of the atomization liquid of the first atomization assembly 20 is greater than that of the second atomization liquid, that is, when the second atomization liquid mainly provides different flavors, the switching of different tastes can be realized by replacing the second atomization assembly 30. When the second atomization liquid is exhausted or the user wants to try other flavors, the entire device does not need to be replaced, only the bottom cover 40 needs to be detached, and the second atomization assembly 30 filled with different flavor atomization liquid needs to be replaced, which is convenient, fast, economical and practical.

[0037] It should be noted that, referring to Figures 2-4, the bottom cover 40 is provided with an air inlet 42, one end of the shell 10 is provided with a mist outlet 13, the first atomization assembly 20 and the second atomization assembly 30 share an air passage, and the mist outlet 13 communicates with the first atomization assembly 20 and the second atomization assembly 30 through the air passage. In use, the user inhales through the mist outlet 13, and the external air enters from the air inlet 42 of the bottom cover 40 and drives the atomized gas mist when passing through the first atomization assembly 20 and the second atomization assembly 30. The two kinds of gas mist are fully mixed in the shared air passage and then output from the mist outlet 13, thereby realizing effective fusion of two different flavors. The size of the air inlet 42 is matched with the corresponding air inlet and air outlet, so that the user has a real smoking feeling when using, and thus, in some embodiments, a sealing element 50 is arranged between the bottom cover 40 and the second containing cavity 12 to seal the second containing cavity 12. By sealing the second containing cavity 12 through the sealing element 50, the gas only enters through the air inlet 42, and no additional gas enters from the side, thereby ensuring accurate control of the air inlet and the integrity of the air flow passage. This design not only provides a more realistic smoking experience, but also avoids the problem of reduced atomization effect caused by air leakage, and also prevents leakage of the atomized liquid.

[0038] Further, with reference to Figure 2 By sealing the second containing cavity 12 through the sealing element 50, the air inlet 42 on the bottom cover 40 can still maintain normal air flow passage with the air outlet when the second atomization assembly 30 is not placed inside the second containing cavity 12. That is, the user can choose to use only the first atomization assembly 20 to provide a basic electronic cigarette experience. This design provides greater flexibility in use: the user can choose to install or not to install the second atomization assembly 30 according to personal preference, and the device can maintain normal air flow passage and good use experience whether or not the second atomization assembly 30 is installed. When the user temporarily does not need additional flavor, the second atomization assembly 30 can be removed, and the device can still maintain normal use of the basic function.

[0039] Further, the sealing element 50 is a sealing ring, and the sealing ring is arranged on the outer peripheral wall of the bottom cover 40. By arranging the annular sealing ring structure on the outer peripheral wall of the bottom cover 40, when the bottom cover 40 is assembled with the second containing cavity 12, the sealing ring is extruded and deformed with the inner wall of the second containing cavity 12, thereby forming a reliable sealing effect. This design not only ensures the air tightness of the second containing cavity 12, but also facilitates disassembly and assembly of the bottom cover 40. When the second atomization assembly 30 needs to be replaced, the bottom cover 40 can be easily disassembled, and the sealing ring can still remain on the outer peripheral wall of the bottom cover 40 without falling off or being damaged. Preferably, the sealing ring is an "O" ring made of rubber.

[0040] In some embodiments, with reference to Figure 2The abutment of the inner peripheral wall of the bottom cover 40 and the outer peripheral wall of the second atomization assembly 30 means that when the second atomization assembly 30 is installed into the second accommodating cavity 12, the inner wall surface of the bottom cover 40 is tightly fitted with the outer wall surface of the second atomization assembly 30. This abutment forms a stable connection through the direct contact of the two surfaces, ensures that the second atomization assembly 30 is fixed in position and cannot shake during use, and at the same time, this abutment also helps to maintain the sealing of the air flow channel, thereby ensuring that when the user uses it, the air can only enter from the air inlet 42 provided on the bottom cover 40, flow through the first atomization assembly 20 and the second atomization assembly 30 through the air channel, and finally be output from the mist outlet 13, which can ensure the stability of the air flow and the atomization effect, so that the base smoke and the smoke with flavor can be fully mixed.

[0041] With reference to Figure 1 , 2 The housing 10 is provided with an opening 14 near the bottom cover 40, which is designed to facilitate the user to disassemble the bottom cover 40. The opening 14 is provided on one side or both sides of the housing 10 and is semicircular. When in use, the user can put his fingers into the opening 14 and use the finger pads to contact the edge of the bottom cover 40 to exert a disassembly force. When it is necessary to replace or check the second atomization assembly 30, the user can easily put his fingers into the semicircular opening 14 and separate the bottom cover 40 from the housing 10 by exerting an outward force. This user-friendly design is particularly suitable for the scenario of replacing the second atomization assembly 30 containing menthol, making the operation more convenient. The semicircular shape of the opening 14 can provide sufficient operating space for the fingers and will not affect the overall aesthetics of the device. At the same time, the presence of the opening 14 will not affect the sealing effect of the sealing ring, ensuring that the device maintains good sealing during use.

[0042] It should be noted that the opening 14 can be provided on one side or on both sides. These two setting methods have their own advantages: when provided on one side, the integrity of the other side of the housing 10 can be maintained, reducing the complexity of mold manufacturing, and at the same time, the basic disassembly requirement can also be met; when provided on both sides, the user can use two fingers to exert force at the same time, making the disassembly more labor-saving and uniform, avoiding the inclination or jamming of the bottom cover 40 during disassembly, which is particularly convenient for users who frequently replace the second atomization assembly 30 containing menthol.

[0043] In some embodiments, with reference to Figure 3 , 4The outer peripheral wall of the bottom cover 40 is provided with a protrusion 41, and the inner wall of the shell 10 is provided with a groove 15 matched with the protrusion 41. The protrusion 41 and the groove 15 are matched for positioning and locking. When the bottom cover 40 is installed on the shell 10, the protrusion 41 on the outer peripheral wall of the bottom cover 40 is matched and clamped with the groove 15 on the inner wall of the shell 10, so as to realize accurate position positioning and reliable fixing effect. This design not only prevents the bottom cover 40 from rotating or loosening during use, but also provides the user with a clear assembly in place feeling when the user replaces the second atomization assembly 30 through the cooperation of the protrusion 41 and the groove 15. When the protrusion 41 is completely embedded in the groove 15, a clear clamping sound and touch feeling are generated, so that the user can confirm that the bottom cover 40 has been correctly installed in place.

[0044] With reference to Figures 2-4 Further comprising a PCB board 60, which is arranged between the first accommodating cavity 11 and the second accommodating cavity 12.

[0045] With reference to Figure 3 , 4 The side of the PCB board 60 close to the second atomization assembly 30 is provided with a spring needle 61, and the second atomization assembly 30 is provided with an electrode 31 electrically connected with the spring needle 61. The PCB board 60 is arranged horizontally between the first accommodating cavity 11 and the second accommodating cavity 12, which not only effectively utilizes the space, but also facilitates overall assembly. In addition, the side of the PCB board 60 close to the second atomization assembly 30 is provided with a spring needle 61, and the second atomization assembly 30 is correspondingly provided with an electrode 31 electrically connected with the spring needle 61. When the second atomization assembly 30 is installed, the spring needle 61 forms a reliable electrical connection with the electrode 31. Since the spring needle 61 structure is adopted, good electrical contact can be ensured during disassembly and assembly, and has a certain buffering effect, preventing component damage caused by excessive installation force. At the same time, the elastic design of the spring needle 61 can compensate for the slight displacement caused by vibration or thermal expansion and contraction during use, ensuring the stability of the electrical connection. The horizontal arrangement of the PCB board 60 not only reduces the overall height of the device, but also provides more space for circuit wiring and component arrangement, making the entire product structure more compact.

[0046] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the above-mentioned embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present application. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
