Description

Technical Field

[0001] This utility model belongs to the field of electronic cigarette technology, and specifically relates to a novel electronic cigarette. Background Technology

[0002] E-cigarettes are electronic products that mimic traditional cigarettes, having the same appearance, smoke, taste, and feel. They work by vaporizing nicotine and other substances, allowing users to inhale the vapor. Using e-cigarettes can help smokers reduce their dependence on nicotine, control their cravings, and become an important means of quitting smoking.

[0003] Currently, common e-cigarettes mainly consist of cartridges (containing e-liquid) and devices (containing batteries and circuit boards). Cartridges and devices come in two types: separate and integrated. With the development of technology and users' complaints about insufficient battery capacity, e-cigarettes with clip-on batteries have gradually come into people's view.

[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN223008473U discloses "an electronic cigarette back clip battery device", which includes a housing, a connecting plate fixedly connected to the bottom of the housing, a limiting block fixedly connected to one end of the connecting plate, a limiting plate fixedly connected to the outer surface of the limiting block, a first locking block fixedly connected to the bottom of the housing near the connecting plate, a back cover snapped into the bottom of the housing, and an L-shaped sliding groove opened on one side of the back cover.

[0049] 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.

[0050] Please see Figures 1-8 The present invention provides the following technical solution: a novel electronic cigarette, comprising a cartridge 1 and a clip-on power supply 2 for providing power to the cartridge 1. The clip-on power supply 2 is detachably connected to the cartridge 1. The cartridge 1 comprises: a cartridge shell 11 with a cavity, a base 12 disposed at the bottom of the cartridge shell 11, a mouthpiece 13 disposed at the top of the cartridge shell 11, a liquid storage cotton 15 disposed in the cartridge shell 11, an air guide tube 17 disposed in the liquid storage cotton 15, a second circuit board 4 disposed in the base 12 and having a second air passage 41, and an air regulating plate 7 slidably disposed in the base 12.

[0051] Furthermore, by Figures 1-4As shown, in this embodiment, the top end of the air duct 17 is connected to the mouthpiece 13, and an atomizing core 18 is provided inside the air duct 17. The atomizing core 18 is connected to the second circuit board 4 through a wire. A large air hole 71 and a small air hole 72 are provided on the air regulating plate 7 and cooperate with the second air passage 41. A toggle block 73 is fixed on the bottom surface of the air regulating plate 7 and passes through the adjustment sliding hole 121 opened at the bottom end of the base 12. With the above solution, when the user uses this new type of electronic cigarette, he first slides the air regulating plate 7 by toggle block 73 and selects the large air hole 71 or the small air hole 72 to cooperate with the second air passage 41 according to his own needs (if the overall size is not considered, more air holes of different sizes can also be set) to adjust the air intake. The back clip power supply 2 provides power to the entire device and is detachably connected to the cartridge 1 for easy charging and replacement.

[0052] When the user inhales, a negative pressure is formed at the mouthpiece 13. Under the action of the pressure difference, the outside air enters the second air passage 41 through the selected air hole (large air hole 71 or small air hole 72) on the air regulating plate 7, and then flows upward along the air guide tube 17. At this time, the second circuit board 4 transmits the electrical energy provided by the back clip power supply 2 to the atomizing core 18. The atomizing core 18 heats up after being powered on.

[0053] The e-liquid is stored in the reservoir cotton 15. Due to capillary action, the e-liquid slowly seeps into the atomizer core 18. When the heated atomizer core 18 comes into contact with the e-liquid, it heats and atomizes the e-liquid into vapor. As the user inhales, the airflow containing the e-liquid vapor continues to rise along the air duct 17 and is eventually inhaled by the user through the mouthpiece 13.

[0054] During this process, users can adjust the air intake by sliding the air adjustment plate 7. When a larger amount of vapor and a richer flavor are needed, the large air hole 71 can be aligned with the second airway 41 to allow more air to enter, thus allowing the atomizing core 18 to atomize more e-liquid. When a smaller amount of vapor and a milder flavor are needed, the small air hole 72 can be aligned with the second airway 41 to reduce the air intake, and correspondingly, the amount of atomized e-liquid will also decrease. This adjustable air intake design allows users to flexibly adjust the user experience according to their preferences.

[0055] In summary, this new type of electronic cigarette is powered by a clip-on power supply 2, uses an air intake plate 7 to adjust the air intake, and combines the atomizing effect of the atomizing core 18 on the e-liquid to achieve the generation and inhalation of e-liquid vapor, providing users with an adjustable user experience.

[0056] Preferably, by Figures 1-5As shown, this embodiment also includes: a limiting slider 74 fixed to the side of the air regulating plate 7, and a limiting groove 122 that cooperates with the limiting slider 74 in the base 12. With the above solution, when in use, the limiting slider 74 added to the side of the air regulating plate 7 and the limiting groove 122 in the base 12 constitute a sliding guide mechanism. This structure plays a key role in the air regulating process: when the user drives the air regulating plate 7 to slide laterally through the toggle block 73, the limiting slider 74 is simultaneously embedded in the limiting groove 122 and moves along its track.

[0057] When the air regulating plate 7 slides to the point where the large air hole 71 or the small air hole 72 is fully aligned with the second air passage 41, the limiting slider 74 will reach the preset end point of the limiting slide groove 122. The physical limiting prevents the air regulating plate 7 from sliding excessively, ensuring that the central axis of the air hole and the air passage are strictly aligned, and avoiding misalignment of the air hole or decrease in sealing due to excessive sliding.

[0058] Preferably, by Figures 1-4 As shown, this embodiment also includes: an insulating plate 3 disposed in the base 12, the insulating plate 3 having a first air passage 31 communicating with the second air passage 41, and the top and bottom surfaces of the insulating plate 3 respectively attached to the second circuit board 4 and the air regulating plate 7. After adopting the above solution, when in use, the insulating plate 3 is made of high temperature resistant insulating material (such as glass fiber reinforced nylon or epoxy resin board), and the surface is sprayed with insulating paint or attached with insulating film.

[0059] On the one hand, the insulating plate 3 forms an insulating barrier between the second circuit board 4 and the gas regulating plate 7 to prevent leakage; on the other hand, the insulating plate 3 plays a supporting role between the second circuit board 4 and the gas regulating plate 7. Through the insulating plate 3, the gas regulating plate 7 is tightly attached to the inner wall of the base 12, and the stability of the gas regulating plate 7 is ensured by friction, so that the gas regulating plate 7 can be stably positioned after adjustment.

[0060] Preferably, by Figures 1-4 As shown, this embodiment also includes: an air guide seat 5 located inside the port of the base 12 and a support plate 16 located at the top of the base 12. The air guide seat 5 has a third air passage 51 communicating with the second air passage 41. The support plate 16 has a stepped hole 161 communicating with the third air passage 51. The bottom end of the air guide tube 17 is embedded in the stepped hole 161. With the above solution, when the user inhales, the airflow follows the following path to complete energy conversion and material transfer: outside air → air hole of the air regulating plate 7 (large air hole 71 / small air hole 72) → first air passage 31 of the insulating plate 3 → second air passage 41 of the second circuit board 4 → third air passage 51 of the air guide seat 5 → stepped hole 161 of the support plate 16 → air guide tube 17 (built-in atomizing core 18) → mouthpiece 13.

[0061] The stepped hole 161 can be matched with air guide tubes 17 of different diameters and ensures that the outer wall of the air guide tube 17 fits tightly with the inner wall of the stepped hole 161, thereby improving the sealing performance. In addition, the stepped hole 161 is also used to support the air guide tube 17 and improve the stability of the air guide tube 17.

[0062] Preferably, by Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, this embodiment also includes: a locking block 123 fixed to the outer wall of the base 12, a locking groove 112 that cooperates with the locking block 123 is provided on the inner wall of the cartridge shell 11, and a guide slope 1231 is provided on the top surface of the locking block 123. With the above solution, when assembling the cartridge shell 11 and the base 12, the cartridge shell 11 is pressed down along the axis of the base 12. The guide slope 1231 of the locking block 123 first contacts the inlet chamfer of the locking groove 112. The guiding effect of the guide slope 1231 automatically corrects the insertion angle deviation, ensuring that the locking block 123 is smoothly aligned with the locking groove 112.

[0063] When the vertical arm of the card block 123 is fully embedded in the card slot 112, the elastic deformation of the material generates a retaining force, making the cartridge shell 11 and the base 12 form a rigid connection.

[0064] Preferably, by Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, the outer wall of the card block 123 is attached to the inner wall of the card slot 112. After adopting the above solution, this close contact during use can not only improve the stability of the connection between the cartridge shell 11 and the base 12, but also greatly improve the sealing of the connection between the cartridge shell 11 and the base 12, thus avoiding leakage.

[0065] In addition, after the cartridge shell 11 is stably connected to the base 12, it can also improve the stability of other internal accessories (such as the insulating plate 3, the second circuit board 4, the air guide seat 5, the air regulating plate 7, and the support plate 16).

[0066] Optionally, by Figure 1 , Figure 7 and Figure 8As shown, in this embodiment, the clip-on power supply 2 includes: a power supply housing 21, a first circuit board 24 disposed inside the power supply housing 21, a rechargeable lithium battery 25 fixed to the surface of the first circuit board 24, a conductive base 26 fixed to the first circuit board 24, and a charging interface 27 fixed to the first circuit board 24. A connector 6 is provided on the second circuit board 4, and a conductive rod 61 that cooperates with the conductive base 26 is provided on the connector 6. With the above scheme, when the clip-on power supply 2 is connected to the cartridge 1, the power transmission path is: rechargeable lithium battery 25 → first circuit board 24 → conductive base 26 (spring pin) → conductive rod 61 (connector 6) → second circuit board 4 (MCU control circuit) → atomizing core 18.

[0067] In the second circuit board 4, the MCU (such as STM8L151) monitors the resistance of the atomizing core 18 in real time. When the conductive rod 61 contacts the conductive base 26 (spring pin), a 100ms preheating pulse is used to eliminate the dry burning phenomenon of the liquid storage cotton 15 at the initial contact, thereby improving the atomization consistency.

[0068] The charging port 27 is a universal Type-C port, used to connect a power cord to charge the rechargeable lithium battery 25.

[0069] Preferably, by Figure 1 , Figure 7 and Figure 8 As shown, this embodiment also includes: a first magnet 14, a positioning block 22, and a second magnet 23. Four diagonally distributed mounting slots 111 are provided on the cartridge 1. The first magnet 14 is fixed in the mounting slot 111. The four positioning blocks 22 are diagonally fixed to the power supply housing 21 and adapted to the mounting slots 111. The second magnet 23 is fixed to the end face of the positioning block 22 and attracts the first magnet 14. With the above scheme, when in use, the first magnet 14 and the second magnet 23 are neodymium iron boron magnets and have opposite magnetic poles.

[0070] Four positioning blocks 22 cooperate with the mounting groove 111 to form mechanical positioning. When the positioning block 22 is embedded in the mounting groove 111, the first magnet 14 and the second magnet 23 attract each other, and at the same time the conductive seat 26 and the conductive rod 61 are electrically connected.

[0071] The clip-on power supply 2 and the cartridge 1 are connected by a combination of "mechanical positioning (positioning block 22 and mounting groove 111) + magnetic attraction (first magnet 14 and second magnet 23)", which ensures a stable connection and prevents accidental separation of the clip-on power supply 2 and the cartridge 1, thus affecting the user experience. In addition, when a positive pulling force is applied (perpendicular to the contact surface of the clip-on power supply 2 and the cartridge 1), the clip-on power supply 2 and the cartridge 1 can be separated when the pulling force is greater than the magnetic attraction force of the first magnet 14 and the second magnet 23, which facilitates charging, disassembly, maintenance or replacement.

[0072] 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.

[0073] Components not described in detail in this article are existing technologies.

[0074] The working principle and usage process of this utility model: When the user uses the electronic cigarette of this utility model, he first slides the air regulating plate 7 by moving the toggle block 73, and selects the large air hole 71 or the small air hole 72 to match the second air channel 41 according to his own needs (if the overall size is not considered, more air holes of different sizes can also be set), thereby adjusting the air intake. The back clip power supply 2 provides power to the entire device, and it is detachably connected to the cartridge 1 for easy charging and replacement.

[0075] When the user inhales, a negative pressure is formed at the mouthpiece 13. Under the action of the pressure difference, the outside air enters the first air passage 31 through the selected air hole (large air hole 71 or small air hole 72) on the air regulating plate 7, and then passes through the second air passage 41, the third air passage 51 and the stepped hole 161 in sequence, and finally flows upward along the air guide tube 17. At this time, the second circuit board 4 transmits the electrical energy provided by the back clip power supply 2 to the atomizing core 18, and the atomizing core 18 heats up after being powered on.

[0076] The e-liquid is stored in the storage cotton 15. Due to capillary action, the e-liquid will slowly seep into the atomizing core 18. When the heated atomizing core 18 comes into contact with the e-liquid, it heats and atomizes the e-liquid into vapor. As the user inhales, the airflow containing the e-liquid vapor continues to rise along the air duct 17 and is finally inhaled by the user through the mouthpiece 13.

[0077] During this process, users can adjust the air intake by sliding the air adjustment plate 7. When a larger amount of vapor and a richer flavor are needed, the large air hole 71 can be aligned with the second airway 41 to allow more air to enter, thus allowing the atomizing core 18 to atomize more e-liquid. When a smaller amount of vapor and a milder flavor are needed, the small air hole 72 can be aligned with the second airway 41 to reduce the air intake, and correspondingly, less e-liquid will be atomized. This adjustable air intake design allows users to flexibly adjust the user experience according to their preferences.

[0078] In summary, this new type of electronic cigarette is powered by a clip-on power supply 2, uses an air intake plate 7 to adjust the air intake, and combines the atomizing effect of the atomizing core 18 on the e-liquid to achieve the generation and inhalation of e-liquid vapor, providing users with an adjustable user experience.

[0079] 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.
