[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 The present invention provides the following technical solution: a dual-flavor electronic cigarette with independent airways, comprising an electronic cigarette body 1 consisting of a cigarette casing 11, a retainer 12, an oil seal seat 13, an oil cup 14, a mouthpiece 15 with an air intake hole 151, a circuit board 16, a rechargeable lithium battery 17, a ceramic atomizing core 18, and a heating element 19. The retainer 12, the circuit board 16, and the rechargeable lithium battery 17 are integrated and installed inside the cigarette casing 11. The circuit board 16 is provided with a charging port 161. The oil seal seat 13, the oil cup 14, and the mouthpiece 15 are connected end to end. The ceramic atomizing core 18 and the heating element 19 are located between the oil seal seat 13 and the oil cup 14. The invention also includes a first silicone sealing ring 2 and a second silicone sealing ring 3.

[0022] The oil cup 14 and the oil seal seat 13 are connected to form two independent oil storage chambers 141 on the inner side. The oil cup 14 has an air passage 142 that communicates with the oil storage chamber 141, and the air intake hole 151 communicates with the air passage 142.

[0023] Furthermore, by Figures 1-3 , Figure 6 As shown, in this embodiment, the oil seal seat 13 and the oil cup 14 are engaged and connected. The first silicone sealing ring 2 is sleeved on the oil seal seat 13 and located in the connection gap between the oil seal seat 13 and the oil cup 14. The bottom end of the oil cup 14 is provided with a positioning ring 147 for installing the ceramic atomizing core 18. The second silicone sealing ring 3 is sleeved on the ceramic atomizing core 18 and located in the connection gap between the ceramic atomizing core 18 and the positioning ring 147. With the above solution, when in use, the user inhales through the air intake hole 151 of the mouthpiece 15. At this time, the inhalation action causes a change in air pressure in the airway 142 (detected by the airflow sensor, not marked in the figure, which is an integrated function of the circuit board 16), triggering the circuit board 16 to control the rechargeable lithium battery 17 to supply power to the heating tube 19. The heating tube 19 heats up rapidly and transfers heat to the ceramic atomizing core 18.

[0024] The e-liquid in the two independent oil storage chambers 141 (which can store different flavors) permeates to the surface of the ceramic atomizing core 18 through contact or capillary action; after the ceramic atomizing core 18 is heated, the e-liquid is atomized into flavored vapor.

[0025] The atomized vapor flows along its corresponding air passage 142 (which is connected to the oil storage chamber 141 one by one), and is finally inhaled by the user through the air intake 151, achieving a dual-flavor smoking experience.

[0026] When the user stops inhaling, the circuit board 16 cuts off the power supply, the heating element 19 stops working, and the atomization process ends.

[0027] Meanwhile, the first silicone sealing ring 2 tightly fills the connection gap between the oil seal seat 13 and the oil cup 14, and the second silicone sealing ring 3 seals the gap between the ceramic atomizing core 18 and the positioning ring 147, effectively preventing the e-liquid in the oil storage chamber 141 from leaking from the connection part, avoiding the failure of the air passage 142 seal or e-liquid leakage due to loosening, ensuring the stability and reliability of the overall operation, and guaranteeing the user's experience.

[0028] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown, this embodiment also includes: two elastic plates 121 and a first locking block 122. The two elastic plates 121 are symmetrically fixed to the top of the retainer 12, and the first locking block 122 is fixed to the outer wall of the elastic plates 121. The top surface of the first locking block 122 has a first guide slope 1221. A locking hole 143 for the first locking block 122 to be inserted is provided on the oil cup 14. The bottom end of the inner side of the oil cup 14 has a third guide slope 144. With the above scheme, in use, in the connection structure between the oil cup 14 and the retainer 12, the two symmetrically distributed elastic plates 121 and the first locking block 122 at their ends constitute a mechanical locking mechanism.

[0029] When the user installs the oil cup 14, the oil cup 14 is pressed downward along the axial direction of the outer shell 11 of the smoking device. The third guide slope 144 at the bottom of the inner side of the oil cup 14 first contacts the first guide slope 1221 of the first locking block 122. As the pressing stroke advances, the third guide slope 144 generates radial extrusion force on the first guide slope 1221, forcing the elastic sheet 121 to bend and deform in the direction of the central axis of the retainer 12, and the first locking block 122 contracts synchronously.

[0030] When the oil cup 14 is pressed down to the predetermined position, the locking hole 143 aligns with the deformed first locking block 122. The elastic sheet 121 recovers its deformation due to its own elasticity, pushing the first locking block 122 into the locking hole 143. At this time, the top surface of the first locking block 122 fits tightly with the locking hole 143, forming a mechanical lock. This not only ensures the axial positioning accuracy of the oil cup 14 and the retainer 12, but also, through the pre-tightening force of the elastic sheet 121, assists the first silicone sealing ring 2 in strengthening the sealing performance between the oil seal seat 13 and the oil cup 14, preventing the e-liquid from leaking between the atomizing chamber and the circuit chamber.

[0031] During the suction process, the axial suction force on the oil cup 14 is transmitted to the retainer 12 through the engagement of the retainer 14 with the first retainer 122 via the retainer 14. Due to the symmetrical support of the elastic sheet 121, the entire oil cup 14 assembly remains stable, avoiding poor contact caused by suction vibration.

[0032] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the outer wall of the first card block 122 is attached to the inner wall of the card hole 143. After adopting the above solution, a secondary physical sealing barrier is formed on the basis of mechanical locking during use.

[0033] When the first card block 122 is inserted into the card hole 143, the mating surfaces of the two can effectively block gas penetration between the atomization chamber and the circuit chamber. Especially when the e-liquid vapor may generate condensate due to temperature difference, the mating surfaces can prevent the condensate from seeping into the circuit board 16 area along the gap of the card hole 143, thus avoiding the risk of short circuit.

[0034] Preferably, by Figure 1 , Figure 3 and Figure 5 As shown, this embodiment also includes: a second locking block 145, which is fixed to the outer wall of the oil cup 14. A second slot 152 for the second locking block 145 to be inserted is provided on the inner wall of the suction nozzle 15. The top surface of the second locking block 145 has a fourth guide slope 1451. With the above solution, when the user fastens the suction nozzle 15 to the top of the oil cup 14, the second locking block 145 on the outer wall of the oil cup 14 first contacts the second slot 152 on the inner wall of the suction nozzle 15.

[0035] The fourth guide slope 1451 forms a guide engagement with the entrance edge of the second slot 152, guiding the second block 145 to slide smoothly into the second slot 152 along the axial direction.

[0036] Preferably, by Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, the outer wall of the second card block 145 is attached to the inner wall of the second card slot 152. After adopting the above solution, during use, the outer wall of the second card block 145 and the inner wall of the second card slot 152 are attached with high precision, forming a rigid sealing layer at the connection interface between the suction nozzle 15 and the oil cup 14.

[0037] This further improves the sealing performance, which is sufficient to counteract the axial tension during suction and prevent air leakage caused by loosening of the nozzle 15.

[0038] Preferably, by Figure 1 , Figure 3 and Figure 5As shown, this embodiment also includes a third locking block 146, which is fixed to the outer wall of the oil cup 14. A first slot 111 for the third locking block 146 to be inserted is provided on the inner wall of the smoking device housing 11. The bottom surface of the third locking block 146 has a fifth guide slope 1461. With the above solution, when the user inserts the oil cup 14 into the smoking device housing 11, the fifth guide slope 1461 of the third locking block 146 first contacts the inlet edge of the first slot 111.

[0039] As the oil cup 14 is axially advanced, the fifth guide slope 1461 decomposes the axial force into a radial component, forcing the oil cup 14 to automatically center itself and ensuring the installation accuracy of the oil cup 14.

[0040] When the oil cup 14 reaches the predetermined position, the bottom surface of the third locking block 146 is completely in contact with the first locking groove 111, forming an axial limit to ensure the stability and sealing of the oil cup 14 during installation.

[0041] Preferably, by Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, the outer wall of the third card block 146 is attached to the inner wall of the first card slot 111. After adopting the above solution, it provides stable support in the radial direction during use, preventing the oil cup 14 from shaking radially during the suction process. At the same time, it forms an auxiliary sealing barrier to prevent external dust or moisture from seeping into the internal circuit from the gap between the oil cup 14 and the outer shell 11 of the smoking device.

[0042] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0043] Components not described in detail in this article are existing technologies.

[0044] The working principle and usage process of this utility model: When using the electronic cigarette of this utility model, the user inhales through the air inlet 151 of the mouthpiece 15. At this time, the inhalation action causes a change in air pressure in the airway 142 (detected by the airflow sensor, not marked in the figure, which is an integrated function of the circuit board 16), triggering the circuit board 16 to control the rechargeable lithium battery 17 to supply power to the heating tube 19. The heating tube 19 quickly heats up and transfers the heat to the ceramic atomizing core 18. The e-liquid in the two independent oil storage chambers 141 (which can store different flavors) permeates to the surface of the ceramic atomizing core 18 through contact or capillary action; after the ceramic atomizing core 18 is heated, the e-liquid is atomized into flavored vapor. The atomized vapor flows along its corresponding air passage 142 (which is connected to the oil storage chamber 141 one by one), and is finally inhaled by the user through the air inlet 151, achieving a dual-flavor smoking experience. When the user stops inhaling, the circuit board 16 cuts off the power supply, the heating tube 19 stops working, and the atomization process ends. Meanwhile, the first silicone sealing ring 2 tightly fills the connection gap between the oil seal seat 13 and the oil cup 14, and the second silicone sealing ring 3 seals the gap between the ceramic atomizing core 18 and the positioning ring 147, effectively preventing the e-liquid in the oil storage chamber 141 from leaking from the connection part, avoiding the failure of the air passage 142 seal or e-liquid leakage due to loosening, ensuring the stability and reliability of the overall operation, and guaranteeing the user's experience.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
