The second sidewall is provided with a first card slot and a second card slot, and the first card slot and the second card slot are arranged along the direction from the second sidewall to the top end. A hook is provided on the sidewall of the cartridge. When the cartridge is inserted into the mouthpiece, the cartridge can switch between a first state and a second state. The first state is that the hook is inserted into the first card slot, and the first end is spaced apart from or in contact with the second seal, so that the second seal seals the through hole, and the sealing assembly isolates the flow channel from the corresponding smoke slot. The second state is that the hook is inserted into the second card slot, so that the first end pushes the second seal away from the through hole, and the flow channel is communicated with the corresponding smoke slot through the through hole.

[0007] In some possible implementation manners, an elastic member is provided between the second seal and the top end. When the cartridge switches from the first state to the second state, the elastic member is compressed. When the cartridge switches back from the second state to the first state, the elastic restoring force of the elastic member is used to push the second seal towards the through hole and reseal the through hole.

[0008] In some possible implementation manners, a convex column is provided on the surface of the top end facing the second seal, and a groove is provided on the surface of the second seal facing the top end.

[0065] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments, and are not intended to limit this application.

[0067] Next, some embodiments of the present application will be described in detail in conjunction with the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0068] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides an electronic cigarette 100, including a cigarette rod 10, a first frame 20, a second frame 30, a cigarette mouthpiece 40, a battery 50, and at least two independent cartridges 60. The first frame 20, the second frame 30, and the battery 50 are all fixed in the cigarette rod 10. Each cartridge 60 is detachably fixed in the cigarette rod 10. The cigarette mouthpiece 40 is detachably fixed inside or outside the cigarette rod 10.

[0069] Specifically, the cigarette rod 10 includes a bottom end 11 and a first side wall 12 connected to the bottom end 11. The bottom end 11 and the first side wall 12 jointly enclose a receiving space 14, and an open end 13 communicating with the receiving space 14 is formed on the side of the first side wall 12 away from the bottom end 11. The first frame 20, the second frame 30, and the battery 50 are all fixed within the receiving space 14, and the first frame 20 and the second frame 30 are respectively used to fix the battery 50 and the cartridge 60. The battery 50 is used to supply power to the cartridge 60. The receiving space 14 is divided into at least two receiving slots. Please refer to Figure 2 , Figure 3 and Figure 4 , and each cartridge 60 can be inserted into one of the receiving slots through the open end 13 and fixed to the second frame 30. The cartridge 60 includes a first end 61 and a second end 62 opposite to the first end 61. At this time, the pin 620 of the second end 62 is connected to the battery 50, so that the battery 50 can supply power to the cartridge 60. The mouthpiece 40 is detachably fixed to the open end 13 of the cigarette rod 10, so that the cartridge 60 is clamped between the second frame 30 and the mouthpiece 40. In some embodiments, when the mouthpiece 40 is fixed to the open end 13 of the cigarette rod 10, the mouthpiece 40 is located within the receiving space 14. Among them, the shape of the mouthpiece 40 can adopt an ergonomic duckbill shape. In other embodiments, the mouthpiece 40 can also be in other shapes such as oval or circular.

[0070] Please also refer to Figures 3 to 5 , the mouthpiece 40 includes a top end 41 and a second side wall 42 connected to the top end 41. The top end 41 and the second side wall 42 jointly enclose at least two smoke slots 400, and each smoke slot 400 corresponds to one of the cartridges 60. An inhalation port 410 communicating with the smoke slot 400 is provided on the top end 41. In some embodiments, the mouthpiece 40 and the cigarette rod 10 are fixed to each other by magnetic adsorption force. Specifically, a first magnetic member 420 is provided on the second side wall 42 of the mouthpiece 40, and a second magnetic member (not shown in the figure) is provided inside the cigarette rod 10. The first magnetic member 420 and the second magnetic member attract each other, so that the mouthpiece 40 and the cigarette rod 10 are fixed to each other. In other embodiments, the mouthpiece 40 and the cigarette rod 10 can also be fixed to each other by a clamping method. The mouthpiece 40 and the cigarette rod 10 can also be made of soft rubber material and fixed to each other by an interference fit method.

[0071] When the cartridge 60 is inserted into the receiving slot and the mouthpiece 40 is fixed to the cigarette rod 10, the first end 61 of the cartridge 60 faces the mouthpiece 40 and extends into the smoke chamber 400, and the second end 62 faces the second frame 30. The cartridge 60 is provided with an e-liquid chamber 63, an atomization core 64 and a flow channel 65. Both the e-liquid chamber 63 and the flow channel 65 can extend in the direction from the first end 61 to the second end 62. The e-liquid chamber 63 is used for loading e-liquid. When the user inhales from the inhalation port 410, the atomization core 64 of the cartridge 60 atomizes the e-liquid in the e-liquid chamber 63 into smoke, and the smoke enters the smoke chamber 400 through the flow channel 65, converges and is inhaled by the user through the mouthpiece.

[0072] Each cartridge 60 can load one type of e-liquid. The e-liquids loaded in at least two cartridges 60 can be different from each other. For example, Figure 4 and Figure 5 As shown in, in some embodiments, the number of cartridges 60 is two, that is, the electronic cigarette 100 is a dual-cartridge electronic cigarette. The two cartridges 60 can be inserted into the cigarette rod 10 at the same time and work simultaneously. Among them, the two cartridges 60 are arranged side by side. When the e-liquid in the e-liquid chambers 63 of different cartridges 60 is atomized into smoke, the smoke can be mixed together after flowing out of the corresponding smoke chambers 400, so that the user can inhale the smoke of the two cartridges 60 at the same time.

[0073] In some other embodiments, only one of the two cartridges 60 can be inserted into the cigarette rod 10, and at this time, the cartridge 60 inserted into the cigarette rod 10 works independently.

[0074] In still some other embodiments, the number of cartridges 60 is not limited to two. For example, the number of cartridges 60 can also be three, that is, the electronic cigarette 100 is a triple-cartridge electronic cigarette.

[0075] By providing at least two cartridges 60 in this application, the at least two cartridges 60 can work simultaneously or independently, so that a variety of different experiences of mixed flavors or single flavors can be combined.

[0076] For example, Figure 4 and Figure 5As shown, there are at least two sealing components 70 provided inside the mouthpiece 40. Each sealing component 70 includes a first seal 71 and a second seal 72. The first seal 71 is disposed between each smoke slot 400 and the corresponding cartridge 60, and the first seal 71 has a through hole 710. The second seal 72 is movably disposed inside the smoke slot 400 and is used to seal the through hole 710. In some embodiments, a protrusion 610 is provided on the outer surface of the first end 61 of the cartridge 60. When the first end 61 of the cartridge 60 is inserted into the mouthpiece 40, the first end 61 can push the second seal 72 away from the through hole 710 through the protrusion 610, so that the flow channel 65 in the cartridge 60 communicates with the corresponding smoke slot 400 through the through hole 710. Therefore, the e-liquid in the e-liquid chamber 63 is atomized into smoke and can enter the smoke slot 400 through the through hole 710, and then is inhaled by the user through the smoke slot 400.

[0077] As Figure 3 and Figure 5 shown, in some embodiments, a first card slot 421 and a second card slot 422 are provided on the second side wall 42 of the mouthpiece 40, and the first card slot 421 and the second card slot 422 are arranged along the direction from the second side wall 42 to the top end 41. A catch 66 is provided on the side wall of the cartridge 60. When the cartridge 60 extends into the mouthpiece 40, the cartridge 60 can switch between a first state and a second state. Among them, the first state is that the catch 66 is inserted into the first card slot 421. At this time, the protrusion 610 of the first end 61 of the cartridge 60 is spaced from or just in contact with the second seal 72. At this time, the second seal 72 seals the through hole 710 of the first seal 71, so that the sealing component 70 isolates the flow channel 65 in the cartridge 60 from the smoke slot 400. Therefore, in the first state, the cartridge 60 is fixed in the mouthpiece 40 but is not in a working state. The second state is that the catch 66 is inserted into the second card slot 422, so that the protrusion 610 of the first end 61 pushes the second seal 72 away from the through hole 710. At this time, the flow channel 65 in the cartridge 60 communicates with the corresponding smoke slot 400 through the through hole 710. Therefore, the second state is the working state of the cartridge 60. Therefore, when the user wants to inhale smoke, after inserting the cartridge 60 into the receiving slot and fixing the mouthpiece 40 to the cigarette rod 10, the user can push the mouthpiece 40 towards the cartridge 60, so that the catch 66 disengages from the first card slot 421 and is inserted into the second card slot 422.

[0078] The mouthpiece 40 of the present application has at least two independent smoke chambers 400. Through the second seal 72, the corresponding smoke chamber 400 can be isolated or communicated with the flow channel 65 of the cartridge 60. Therefore, the user can choose to insert only one cartridge 60. By pushing the mouthpiece 40, the second seal 72 corresponding to the cartridge 60 is disengaged from the through hole 710, so that the cartridge 60 is communicated with the corresponding smoke chamber 400. At this time, the user can inhale the smoke introduced through the flow channel 65. The user can also choose to insert at least two cartridges 60 at the same time. By pushing the mouthpiece 40, the second seals 72 corresponding to the at least two cartridges 60 are disengaged from the through hole 710. At this time, the user can inhale the smoke mixed and introduced by the at least two cartridges 60. Therefore, the electronic cigarette 100 of the present application has a flexible usage method, which is beneficial to improving the user experience.

[0079] As Figure 4 and Figure 5 shown, in some embodiments, an elastic member 73 may be provided between the second seal 72 and the top end 41 of the mouthpiece 40. When the cartridge 60 is in the first state, the elastic member 73 is in a free state. When the cartridge 60 is switched from the first state to the second state, the elastic member 73 is compressed. When the cartridge 60 is switched back from the second state to the first state, the elastic restoring force of the elastic member 73 is used to push the second seal 72 toward the through hole 710 and reseal the through hole 710. Among them, the elastic member 73 may be a helical cylindrical spring.

[0080] Furthermore, a convex post 411 may be provided on the inner surface of the top end 41 of the mouthpiece 40, that is, the convex post 411 and the protrusion 610 are respectively located on two opposite surfaces of the top end 41. Correspondingly, a groove 720 may be provided on the surface of the second seal 72 facing the top end 41. One end of the elastic member 73 is sleeved outside the convex post 411, and the opposite end is provided in the groove 720, so that the elastic member 73 elastically abuts between the top end 41 and the second seal 72.

[0081] In some embodiments, an oil-absorbing cotton 74 may also be provided in the mouthpiece 40. The oil-absorbing cotton 74 is used to absorb the e-liquid overflowing from the cartridge 60, thereby reducing the risk of oil leakage of the electronic cigarette 100.

[0082] Please refer to Figure 4 、 Figure 6 and Figure 7, in some embodiments, a mixing device 80 is provided between adjacent smoke troughs 400. The mixing device 80 is configured to fully mix the smoke from at least two smoke troughs 400, and the mixed smoke is discharged from the suction port 410. In some embodiments, the mixing device 80 includes a hollow housing 81 and a plurality of vanes 82 disposed within the housing 81. The plurality of vanes 82 are divided into a plurality of first vanes 821 arranged in parallel and a plurality of second vanes 822 arranged in parallel. The first vanes 821 are located between the second vanes 822 and the cartridge 60. The arrangement direction of the plurality of first vanes 821 is different from the arrangement direction of the plurality of second vanes 822, so that the smoke from at least two smoke troughs 400 is fully mixed in the path of passing through the first vanes 821 and the second vanes 822 in sequence. For example, the arrangement direction of the plurality of first vanes 821 may be perpendicular to the arrangement direction of the plurality of second vanes 822.

[0083] Please refer to Figure 8 , in some other embodiments, the mixing device 80 includes a hollow housing 81 and a plurality of vanes 82 disposed within the housing 81. Along the direction from the second end 62 to the first end 61, the plurality of vanes 82 are helically arranged, so that the smoke from at least two smoke troughs 400 is fully mixed in the path of passing through the plurality of vanes 82.

[0084] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and essence of the technical solutions of the present application.
