Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette with switchable flavors. Background Technology

[0002] In the field of e-cigarette technology, as consumers' demands for the e-cigarette user experience continue to increase, e-cigarettes with switchable flavors have gradually attracted widespread attention. These e-cigarettes allow users to switch between different flavors, greatly enriching users' choices and meeting diverse needs.

[0003] However, existing flavor-switching e-cigarettes often have relatively simple flavor-switching mechanisms, typically relying solely on manual rotation or sliding by the user to switch between different flavor cartridges. This method lacks an effective positioning mechanism. In actual use, the rotating component is easily rotated by slight external touches or user misoperation, causing a change in the connection position between the smoke guide channel and the cartridge component. This makes it impossible for the user to accurately switch to the desired flavor, severely impacting the convenience and accuracy of use and causing considerable inconvenience. Therefore, this paper presents a flavor-switching e-cigarette to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a flavor-switching electronic cigarette that addresses the shortcomings of existing technologies by solving the technical problem that existing flavor-switching electronic cigarettes do not have a precise positioning function.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A flavor-switching electronic cigarette includes a main body and a top cover mounted on the top of the main body. The main body contains at least two cartridge components for storing e-liquids of different flavors. A rotating component is rotatably provided on the top surface of the top cover. The rotating component is formed with a mouthpiece and a smoke guide channel communicating with the mouthpiece. The bottom end of the smoke guide channel is connected to one of the cartridge components.

[0007] An extension is formed in the middle of the top surface of the top cover, and a central shaft is formed on the bottom surface of the rotating part. The central shaft can rotate and / or slide up and down on the extension. The rotating part is formed with a positioning groove, and the top cover is formed with positioning protrusions in a number that are consistent with the number of tobacco cartridge components and correspond one-to-one with them. When the smoke guide channel is connected to one of the tobacco cartridge components, the positioning protrusion corresponding to that tobacco cartridge component is embedded in the positioning groove.

[0008] Furthermore, a movable chamber is formed within the extension, and a central hole communicating with the movable chamber is formed at the top of the extension. The diameter of the central hole is smaller than the cross-sectional dimension of the movable chamber, and the central shaft passes through the central hole and is placed inside the movable chamber.

[0009] Furthermore, a screw is installed at the bottom of the central shaft placed in the movable chamber, and a limiting piece with a width greater than the diameter of the central hole is formed at the head of the screw. A spring for applying downward pressure to the limiting piece is wound on the central shaft placed in the movable chamber; the spring is placed in the movable chamber and is positioned between the top wall of the movable chamber and the limiting piece.

[0010] Furthermore, the inner side of the top cover is formed with a number of insertion tubes that are the same as the number of cartridge components, and each insertion tube is connected to a different cartridge component; the bottom end of the smoke guide channel is connected to the top end of one of the insertion tubes.

[0011] Furthermore, the cartridge component includes a cartridge case, a top sealing seat on the top of the cartridge case, and a bottom sealing seat on the bottom of the cartridge case. The cartridge case, the top sealing seat, and the bottom sealing seat form an atomizing chamber. An oil storage cotton for storing e-liquid is provided inside the atomizing chamber, and an atomizing device for atomizing the e-liquid is provided inside the oil storage cotton. The top sealing seat is formed with a smoke outlet that communicates with the atomizing device, and the smoke outlet is inserted into the connector.

[0012] Furthermore, an oil-absorbing cotton is provided between the top sealing seat and the inner top wall of the upper cover to prevent e-liquid leakage.

[0013] Furthermore, a bottom cover is installed at the bottom of the main body, and a circuit board electrically connected to the atomizing device is installed inside the bottom cover. A battery electrically connected to the circuit board is installed inside the main body, and the circuit board is provided with a charging port for charging the battery. The bottom cover is formed with several air inlets for allowing outside air to enter the atomizing device, and a regulating valve for controlling the number of air inlets that are open or closed is rotatably provided at the bottom of the bottom cover.

[0014] Furthermore, the top of the cover is formed with an installation chamber, which contains condensation cotton for absorbing e-liquid that has not been fully atomized. The condensation cotton is placed between the plug tube and the smoke guide channel. The installation chamber also contains a silicone pad placed above the condensation cotton. The silicone pad is formed with a number of inserts that are the same as the number of plug tubes. Each insert is embedded in a different plug tube. The silicone pad is placed between the plug tube and the smoke guide channel.

[0015] Furthermore, the cross-sectional dimensions of the silicone pad are smaller than those of the condensation cotton.

[0016] Furthermore, the outer edge of the top cover is formed with a number of positioning marks that are the same as the number of tobacco cartridge components. Several positioning marks correspond one-to-one with different numbers of tobacco cartridge components. The rotating part is formed with a pointer for pointing to one of the positioning marks, and the pointer is aligned with the smoke guide channel.

[0017] The beneficial effects of this invention are as follows: When a user smokes using the mouthpiece, outside air enters the cartridge component corresponding to the smoke guide channel. Upon sensing the air passage, the cartridge component activates, heating the e-liquid inside to generate smoke. The air then carries the smoke out through the smoke guide channel for the user to inhale. When the user needs to switch flavors, pulling the mouthpiece upwards moves the rotating component upwards as well, causing the central shaft to slide upwards on the extension. At this point, the positioning protrusion disengages from the positioning groove. The mouthpiece is then rotated, causing the central shaft to rotate on the extension until the smoke guide channel aligns with another cartridge component. Pushing the mouthpiece downwards causes the central shaft to slide downwards on the extension, connecting the smoke guide channel with the aligned cartridge component. The positioning protrusion corresponding to that cartridge component then embeds into the positioning groove, repositioning the rotating component. Regardless of which cartridge component the smoke guide channel connects to, positioning is achieved through the positioning protrusion and positioning groove, preventing accidental rotation of the rotating component and improving the user experience. Furthermore, the user can switch smoke flavors anytime, anywhere according to their needs, enhancing the practicality of this electronic cigarette. Attached Figure Description

[0024] The following is a detailed description of an electronic cigarette with switchable flavors according to the present invention, with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, an embodiment of the present invention, a flavor-switching electronic cigarette, includes a cylindrical body 1. A top cover 2 is fixedly mounted on the top of the body 1, and a bottom cover 3 is fixedly mounted on its bottom. Inside the body 1 is a support frame 6, which houses at least two cartridge components for heating and atomizing e-liquid. Each cartridge component stores e-liquid of a different flavor. When using the electronic cigarette, the user can generate vapors of different flavors. The inner side of the top cover 2 has a number of insertion tubes 19 matching the number of cartridge components. Each insertion tube 19 is connected to a different cartridge component. A rotating component 4 is rotatably mounted on the top surface of the top cover 2. The rotating component 4 has a mouthpiece 5 and a smoke guide channel 51 connected to the mouthpiece 5. The bottom end of the smoke guide channel 51 is connected to one of the insertion tubes 19. When a user smokes using the mouthpiece 5, outside air enters the cartridge component corresponding to the smoke guide channel 51. Upon sensing the air passing through, the cartridge component activates, heating the e-liquid inside to produce smoke. The air then carries the smoke out, through the connector 19 and the smoke guide channel 51, for the user to inhale. When the user wants to inhale a different flavor of smoke, they rotate the rotating component 4, connecting the smoke guide channel 51 on the rotating component 4 to another connector 19, which also connects to the cartridge component corresponding to that connector 19. At this time, when the user smokes using the mouthpiece 5, the cartridge component corresponding to the smoke guide channel 51 activates, allowing the user to inhale a different flavor of smoke.

[0026] Furthermore, the cartridge component includes a cartridge case 7, with a top sealing seat 8 at the top and a bottom sealing seat 9 at the bottom. The cartridge case 7, the top sealing seat 8, and the bottom sealing seat 9 form an atomizing chamber. An oil-storing cotton 10 for storing e-liquid is provided inside the atomizing chamber, and an atomizing device 11 for atomizing the e-liquid is installed within the oil-storing cotton 10. The top sealing seat 8 has a smoke outlet 12 communicating with the atomizing device 11, which is inserted into the connector 19. When the user smokes through the mouthpiece 5, outside air enters the atomizing device 11. Simultaneously, the atomizing device 11 is activated, heating and atomizing the e-liquid. Finally, the air carries the smoke out of the atomizing device 11, passing sequentially through the smoke outlet 12, the connector 19, and the smoke guide channel 51 for the user to inhale. An absorbent cotton 13 is provided between the top sealing seat 8 and the inner top wall of the top cover 2 to prevent e-liquid leakage. When the e-liquid in the e-liquid atomization chamber leaks out from the gap between the smoke outlet 12 and the plug tube 19, it will be absorbed by the absorbent cotton 13 to prevent the e-liquid from continuing to leak and improve the service life of this electronic cigarette.

[0027] When using this electronic cigarette, to prevent the rotating part 4 from rotating due to accidental contact, an upwardly extending portion 24 is formed at the center of the top surface of the top cover 2, and a central shaft 27 is formed on the bottom surface of the rotating part 4, which is movably connected to the extension portion 24. The central shaft 27 can rotate and / or slide up and down inside the extension portion 24. A positioning groove 31 is formed on the bottom surface of the rotating part 4, and a positioning protrusion 32 is formed on the top surface of the top cover 2, the number of which is the same as the number of insertion tubes 19 and corresponds one-to-one with the insertion tubes 19. When the smoke guide channel 51 is connected to one of the insertion tubes 19, the positioning protrusion 32 corresponding to that insertion tube 19 is embedded in the positioning groove 31. The rotating part 4 is positioned by the cooperation of the positioning protrusion 32 and the positioning groove 31 to prevent the rotating part 4 from rotating due to accidental contact.

[0028] When the user needs to switch flavors, they pull the mouthpiece 5 upwards, causing the rotating component 4 to move upwards as well. This allows the central shaft 27 to slide upwards inside the extension 24. At this time, the positioning protrusion 32 disengages from the positioning groove 31. Then, the mouthpiece 5 is rotated, and the central shaft 27 rotates inside the extension 24. After the smoke guide channel 51 aligns with another connector 19, the mouthpiece 5 is pushed downwards, and the central shaft 27 slides downwards inside the extension 24. When the smoke guide channel 51 connects with the aligned connector 19, the positioning protrusion 32 corresponding to that connector 19 is embedded in the positioning groove 31, repositioning the rotating component 4. Regardless of which connector 19 the smoke guide channel 51 connects to, positioning can be achieved through the positioning protrusion 32 and the positioning groove 31.

[0029] Furthermore, a movable chamber 25 is formed within the extension 24, and a central hole 26 communicating with the movable chamber 25 is formed at the top of the extension 24 (e.g., ...). Figure 4 As shown, the diameter of the central hole 26 is smaller than the cross-sectional dimension of the movable chamber 25, and the central shaft 27 passes through the central hole 26 and is placed inside the movable chamber 25; by providing the movable chamber 25 in the extension 24, the central shaft 27 can not only slide up and down in the extension 24, but also rotate.

[0030] To prevent the rotating part 4 from moving up and down automatically, a screw 28 is installed at the bottom of the central shaft 27 placed in the movable chamber 25. A limiting piece 29 with a width larger than the diameter of the central hole 26 is formed at the head of the screw 28. A spring 30 for applying downward pressure to the limiting piece 29 is wound around the central shaft 27 placed in the movable chamber 25. The spring 30 is placed in the movable chamber 25 and between the top wall of the movable chamber 25 and the limiting piece 29. When the central shaft 27 moves upward in the movable chamber 25, it moves upward with the limiting piece 29, and the spring 30 is compressed. When the central shaft 27 is rotated, the spring 30 is still in a compressed state. When the upward force on the mouthpiece 5 is stopped, the limiting piece 29 is applied downward under the action of the compressed spring 30. After the pressure is transmitted to the rotating part 4, the rotating part 4 automatically returns to its downward position. In addition, under the downward pressure applied by the spring 30 to the rotating part 4, and under the positioning protrusion 32 and the positioning groove 31 to position the rotating part 4, the rotating part 4 will not rotate or move up and down after being accidentally touched, thus improving the user experience of this electronic cigarette.

[0031] In this embodiment, to power the atomizing device 11, a circuit board 15 electrically connected to the atomizing device 11 is installed inside the bottom cover 3. A battery 14 electrically connected to the circuit board 15 is installed inside the main body 1. The circuit board 15 has a charging port 16 for charging the battery 14. The battery 14 can be charged by plugging the charging cable into the charging port 16. The bottom cover 3 is formed with several air inlets 17 for allowing outside air to enter the atomizing device 11. The main body 1 also has a microphone (not shown in the figure) for detecting airflow. The microphone is an airflow sensor. When the user smokes, outside air enters the atomizing device 11 through the air inlets 17. After the air is detected by the microphone, the operation of the atomizing device 11 is controlled. The microphone, battery 14, circuit board 15, charging port 16, and air inlets 17 are all prior art and will not be described in detail here. A regulating valve 18 is rotatably provided at the bottom of the bottom cover 3 to control the number of air inlets 17 that are open or closed. By rotating the regulating valve 18, the air inlets 17 can be blocked or connected to the outside air. The more air inlets 17 are blocked by the regulating valve 18, the less air enters the atomizing device 11, and the lower the power of the atomizing device 11. Conversely, the fewer air inlets 17 are blocked by the regulating valve 18, the more air enters the atomizing device 11, and the higher the power of the atomizing device 11.

[0032] like Figure 4As shown, the top of the upper cover 2 has a mounting chamber 20 formed on its top. The mounting chamber 20 contains condensing cotton 21 for absorbing e-liquid that has not been fully atomized. The condensing cotton 21 is placed between the connector 19 and the smoke guide channel 51. After the atomizing device 11 atomizes the e-liquid, the smoke is guided through the connector 19 and the smoke guide channel 51. If any e-liquid that has not been fully atomized leaks out from the gap between the connector 19 and the smoke guide channel 51, it will be absorbed by the condensing cotton 21 to prevent further leakage. To improve the sealing effect after the connector 19 and the smoke guide channel 51 are connected, a silicone pad 22 is also installed in the mounting chamber 20, placed above the condensing cotton 21. The silicone pad 22 has a number of embedded tubes 23 that are the same number as the connectors 19. Each embedded tube 23 is embedded in a different connector 19. The silicone pad 22 is placed between the connector 19 and the smoke guide channel 51. By embedding the insert 23 into the insertion tube 19, the silicone pad 22 can be stably installed in the installation chamber 20, and the condensation cotton 21 can also be limited, thus stably installing the condensation cotton 21 in the installation chamber 20. In addition, the silicone pad 22 is placed between the insertion tube 19 and the smoke guide channel 51 to improve the sealing between the two and prevent air from escaping from the gaps when smoking.

[0033] The cross-sectional size of the silicone pad 22 is smaller than that of the condensation cotton 21, so that the e-liquid that is not fully atomized can be absorbed by the condensation cotton 21 whether it comes from above or below the silicone pad 22. This not only improves the sealing effect after the connector 19 and the smoke channel 51 are connected, but also prevents the e-liquid from continuing to leak.

[0034] The outer edge of the top cover 2 has a number of positioning marks 34 that match the number of tobacco cartridge components. Each positioning mark 34 corresponds to a different number of tobacco cartridge components. The rotating part 4 has a pointer 33 pointing to one of the positioning marks 34, and the pointer 33 is aligned with the smoke guide channel 51. When the pointer 33 points to one of the positioning marks 34, the tobacco cartridge component corresponding to that positioning mark 34 will connect with the smoke guide channel 51, improving the accuracy of flavor adjustment.

[0035] In this embodiment, the outer wall of the main body 1 is formed with an annular snap-fit ​​groove 35, and a buckle 36 is snapped into the snap-fit ​​groove 35. The buckle 36 is formed with a clip portion 37 for clipping the electronic cigarette in a designated position for easy carrying. When the user does not need to use the electronic cigarette, the clip portion 37 is fastened to the edge of a pocket or other location. With the elasticity of the clip portion 37 and the cooperation of the outer wall of the main body 1, the electronic cigarette is clipped to the edge of the pocket for easy carrying.

[0036] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0037] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
