[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1-Figure 3 As shown, an electronic cigarette with a flavor conversion function of the present invention comprises a housing 1, wherein a cartridge installation cavity, a sealed mainboard installation cavity and an airway 17 are formed inside the housing 1, and a mouthpiece 2 is arranged on the housing 1, and the mouthpiece 2 is arranged corresponding to the airway 17; It also includes a multi-flavor cigarette cartridge 100, which is movably arranged in the cigarette cartridge installation cavity. By applying suction or blowing force to the cigarette holder 2, the multi-flavor cigarette cartridge 100 is controlled to move up and down along the cigarette cartridge installation cavity to switch the flavors of the multi-flavor cigarette cartridge 100. The number of multi-flavor cigarette cartridges 100 can be multiple, such as two or three; It also includes an airway 17 switching component, which is push-type arranged on the shell 1. By pressing the airway 17 switching component, the airflow is used to control the up and down movement of the multi-flavor cigarette cartridge 100 in the cigarette cartridge installation cavity. When the airway 17 switching component is not pressed, only the suction action can be realized, and the suction action will not switch the flavor of the cigarette cartridge. Only when the airway 17 switching component is pressed, the suction action can be switched to the switching action of the cigarette cartridge flavor.

[0022] In this embodiment, the multi-flavor cigarette cartridge 100 has three independent small cigarette cartridges inside, each small cigarette cartridge is used to store cigarette liquid of different flavors, and three groups of conductive contacts 27 are arranged on the multi-flavor cigarette cartridge 100 along the height direction, and each group of conductive contacts 27 corresponds to a small cigarette cartridge. The multi-flavor cigarette cartridge 100 can switch to cigarette cartridges of different flavors when it reaches different heights. After switching to the conductive position, the corresponding conductive contacts 27 are in contact and conduct electricity, so that the corresponding cigarette cartridge can be heated; A control mainboard 9 and a battery 8 are installed in the mainboard installation cavity. The battery 8 is connected to the control mainboard 9. A charging interface 6 is arranged on the control mainboard. An elastic conductive sheet 11 is arranged on the side of the control mainboard 9 facing the multi-flavor cigarette cartridge 100. One end of the elastic conductive sheet 11 is conductively connected to the top position of the control mainboard 9. The other end of the elastic conductive sheet 11 is an active end and extends toward the bottom surface of the mainboard installation cavity. A conductive sealing sheet 19 is arranged at the bottom active end of the elastic conductive sheet 11. The conductive sealing sheet 19 is used to conduct or seal the bottom of the shell 1. The first air inlet 7, the position corresponding to the multi-flavor cigarette cartridge 100 on the elastic conductive sheet 11 is also provided with a conductive contact pin 26. When the airway 17 switching component is not pressed, the conductive contact pin 26 is in conductive contact with the conductive contact point 27. When the airway 17 switching component is pressed, the elastic conductive sheet 11 is elastically deformed under pressure, so that the conductive contact pin 26 is separated from the conductive contact 27. At this time, the power connection is disconnected. After the cigarette cartridge switches the height position, the squeezing of the elastic conductive sheet 11 is released, so that the conductive contact point 27 on the corresponding cigarette cartridge can be in contact with the conductive contact pin 26, and the power supply to the corresponding cigarette cartridge is completed. Figure 5 As shown,.

[0023] Among them, Figure 5 As shown, three positioning slots 28 are equidistantly arranged on the multi-flavor cigarette cartridge 100 along the height direction, each positioning slot 28 is arranged corresponding to a group of conductive contacts 27, and a positioning plug 29 is arranged on the elastic conductive sheet 11 at the bottom of the conductive contact pin 26. When the conductive contact pin 26 is in conductive contact with the conductive contact 27, the positioning plug 29 is inserted into the positioning slot 28 to complete the fixed positioning of the cigarette cartridge in height. After pressing the elastic conductive sheet 11, the positioning plug 29 can be separated from the positioning slot 28. At this time, the suction airflow can make the cigarette cartridge change in height, as shown in FIG. Figure 7 shown.

[0024] like Figure 3As shown, a first sealing portion 21 is provided at the upper end of the multi-flavor cigarette cartridge 100, and a second sealing portion 14 is provided at the bottom of the multi-flavor cigarette cartridge 100, the first sealing portion 21 and the second sealing portion 14 are in sealing contact with the inner wall of the cigarette cartridge installation cavity, a first magnetic ring is embedded in the first sealing portion 21, and a second magnetic ring 22 is also embedded in the cigarette cartridge installation cavity, a first limit stop ring 23 is provided at the top position of the multi-flavor cigarette cartridge 100 in the cigarette cartridge installation cavity, and a second limit stop ring 15 is provided at the bottom position of the multi-flavor cigarette cartridge 100, a cigarette cartridge travel gap cavity is formed between the first limit stop ring 23 and the second limit stop ring 15, and the multi-flavor cigarette cartridge 100 can move up and down in the cigarette cartridge travel gap cavity, and the second magnetic ring 22 is located at the cigarette cartridge travel gap cavity. In the middle position, the multi-flavor cigarette cartridge 100 has three conductive positions, a cigarette cartridge air inlet is arranged at the top of the first sealing part 21, and a plurality of atomization air outlets 16 are arranged at the bottom of the second sealing part 14. The space at the bottom of the second sealing part 14 forms a smoke outlet chamber, and the smoke outlet chamber is connected to the airway 17 through a smoke outlet 18, and the smoke outlet chamber is connected to the first air inlet 7. The multi-flavor cigarette cartridge 100 has three positioning points, namely the extreme position of the top position, the middle magnetic ring position and the extreme position of the bottom. When the multi-flavor cigarette cartridge 100 is located at these three positions, the conductive contact pin 26 and the conductive contact point 27 are arranged corresponding to each other, and the conductive connection of the multi-flavor cigarette cartridge 100 can be completed at this time. Of course, if the number of cigarette cartridges increases, more position positioning can be achieved by increasing the number of magnetic rings in the height direction.

[0025] The conductive sealing sheet 19 is provided with a first conductive hole 20. When the elastic conductive sheet 11 is pressed, the first conductive hole 20 faces the first air inlet 7. When the elastic conductive sheet 11 is not pressed, the conductive sealing sheet 19 seals the first air inlet 7. Figure 4 As shown, in the normal state, air enters the top of the cigarette cartridge and exhausts air through the atomization air outlet 16 at the bottom. The smoke gas enters the airway 17 through the smoke outlet 18 and is then discharged from the mouthpiece 2 to achieve the purpose of suction. At this time, the first air inlet 7 cannot take in air to inhale external air. Once the elastic conductive sheet 11 is pressurized, it means that the multi-flavor cigarette cartridge 100 is switched in the height direction. At this time, after the first conducting hole 20 is connected to the first air inlet 7, as the multi-flavor cigarette cartridge 100 rises and falls, the first air inlet 7 can be used as an air inlet and outlet to meet the up and down movement of the multi-flavor cigarette cartridge 100.

[0026] Among them, Figure 3 and Figure 7As shown, the airway 17 switching assembly includes a pressing seal 5, one end of the pressing seal 5 extends out of the housing 1, and the other end extends into the cartridge installation cavity, and a positioning sleeve 12 is also provided in the cartridge installation cavity at one end thereof, and one end of the pressing seal 5 extends into the positioning sleeve 12, and the positioning sleeve 12 is connected to the mainboard installation cavity; A sealing partition 10 is arranged at the top of the pressing seal 5 in the cigarette cartridge installation cavity, a sealing docking portion 32 is fixedly arranged at the bottom of the sealing partition 10, a second conduction hole 31 is arranged on the sealing partition 10, a third conduction hole 30 is arranged on the sealing docking portion 32, and a fourth conduction hole 25 is arranged on the sealing pressing member. When the pressing seal 5 is not pressed, the second conduction hole 31, the third conduction hole 30 and the fourth conduction hole 25 are respectively connected and conducted, a second air inlet 3 is arranged on the top of the housing 1, and the bottom surface of the sealing docking portion 32 is an arc-shaped contact surface, which is arc-sealed with the outer cylindrical surface of the arc-shaped pressing seal 5. When the pressing seal 5 is pressed, the second conduction hole 31 and the third conduction hole 30 are sealed by the pressing seal 5. When the pressing seal 5 is not pressed, the third conduction hole 30, the second conduction hole 31 and the fourth conduction hole 25 are connected. At this time, air is taken in by the second air inlet 3 to realize the normal operation of the cigarette cartridge. Once the pressing seal 5 is squeezed, the fourth conduction hole 25 is misaligned with the second and third conduction holes 30. Due to the provision of the sealing docking portion 32 and the arc-shaped sealing pressing member arc-shaped sealing contact, after the misalignment, the airflow isolation can be realized. At this time, the multi-flavor cigarette cartridge 100 can be lifted up and down by suction through the cigarette holder 2.

[0027] The sealing pressing member is provided with a docking air guide hole 24 , and when the pressing sealing member 5 is not pressed, the docking air guide hole 24 is in communication with the air passage 17 .

[0028] like Figure 7 As shown, a first adapter air channel 417 is also provided on the pressing seal 5, and a second adapter air channel 3317 is also provided on the shell 1. When the pressing seal 5 is pressed, the first adapter air channel 417 and the second adapter air channel 3317 are connected and connected. At this time, the cigarette cartridge mounting cavity and the air channel 17 are connected and connected, and the docking air guide hole 24 is sealed. When the first adapter air channel 417 and the second adapter air channel 3317 are connected and connected, suction can be used to realize the up and down lifting control of the multi-flavor cigarette cartridge 100, and the originally extended part of the pressing seal 5 is extended into the air channel 17 to seal the air channel 17. The outer diameter of the pressing seal 5 is larger than the inner diameter of the air channel 17.

[0029] Among them, a return spring 13 is also installed between the sealing docking part 32 and the positioning sleeve 12. The return spring 13 is located on one side of the sealing docking part 32 to form a bent buckle part. The bent buckle part is buckled into the limiting buckle groove set on the pressing seal 5 and sealed and fixed with glue. In this way, when the pressing seal 5 is pressed, the return spring 13 is continuously compressed, and the pressing seal 5 is reset by the return spring 13.

[0030] When the multi-flavor cigarette cartridge 100 is located at the position of the first limit stop ring 23, the first flavor of the multi-flavor cigarette cartridge 100 is obtained; When the multi-flavor cigarette cartridge 100 is located at the second magnetic ring 22, the second flavor of the multi-flavor cigarette cartridge 100 is obtained; When the multi-flavor cigarette cartridge 100 is located at the second position limiting retaining ring 15, the third flavor of the multi-flavor cigarette cartridge 100 is obtained.

[0031] The present invention abandons the traditional complicated operation of manually pressing buttons multiple times to switch flavors. The user can quickly switch the flavors of the cartridges through a simple inhalation or blowing action, which not only simplifies the operation steps, but also effectively avoids the poor experience caused by misoperation or mispressing. Secondly, the present invention does not need to rely on visual judgment and button operation. Even in a dark or lightless environment, the user can easily switch the flavor of the cartridge, meeting the needs in a variety of usage scenarios; in addition, by providing a plurality of independent small cartridges and corresponding conductive contacts 27 in the multi-flavor cartridge 100, and combining the airway 17 switching component controlled by the airflow, the stability and reliability of the switching process are ensured, and the occurrence of problems such as air leakage and cartridge mismatch is avoided; At the same time, the airflow switching method is combined with the lifting and lowering movement of the cartridge, making the switching process more intuitive and smooth, effectively improving the user's usage efficiency.

[0032] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
