Abstract
Description
Technical Field
[0001] This application belongs to the technical field of electronic cigarettes, and specifically relates to an electronic cigarette. Background Technology
[0002] To prevent minors from using e-cigarettes, most current e-cigarettes incorporate some form of identity verification. Identity verification technology is fast and reliable, making it suitable for application in e-cigarettes to prevent minors from using them.
[0003] In related technologies, the identification module is set on the front of the e-cigarette shell in the form of a circle or square. This not only occupies a large area on the surface of the e-cigarette shell, making the e-cigarette bulky, but also makes it easy to be accidentally touched, increasing the false trigger rate and affecting the power consumption of the e-cigarette. Utility Model Content
[0004] The purpose of this application is to provide an electronic cigarette that can solve the problems of large electronic cigarette size and high false trigger rate caused by the large area occupied by the identity recognition module.
[0005] To solve the above-mentioned technical problems, this application is implemented as follows:
[0006] This application provides an electronic cigarette, including: a housing and a fingerprint sensor;
[0007] The housing includes a front side and a side side arranged adjacent to each other, wherein the width of the side side is smaller than the width of the front side, so that the housing has a flat structure;
[0008] The fingerprint sensor is located on the side, and the side forms a finger contact area for the user's finger to touch.
[0009] In this embodiment, the width of the side of the housing is smaller than the width of the front, so that the housing has a flat structure. The fingerprint sensor is placed on the side of the housing. Compared with placing the fingerprint sensor on the front, this embodiment can reduce the space occupied by the fingerprint sensor on the surface of the e-cigarette housing, which is conducive to the miniaturization of the e-cigarette design, making the e-cigarette easier to carry, and also helps to improve the appearance of the e-cigarette. Furthermore, since the fingerprint sensor occupies a small area, the probability of accidental touch is reduced, so that the e-cigarette will not be accidentally activated, thereby helping to reduce the power consumption of the e-cigarette.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0028] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.
[0029] refer to Figure 1 and Figure 9 This application discloses an electronic cigarette, which includes a housing 10 and a fingerprint sensor 21.
[0030] The housing 10 is a basic component that provides a base for mounting and housing the fingerprint sensor 21; the fingerprint sensor 21 is a detection component that can identify the user's fingerprint information.
[0031] like Figure 4 As shown, the housing 10 may include a front side 11 and a side side 12 arranged adjacent to each other. The width of the side side 12 is smaller than the width of the front side 11, so that the housing 10 has a flat structure. The fingerprint sensor 21 may be disposed on the side side 12 of the housing 10 to reduce the space occupied by the integrated module 20 on the surface of the housing 10.
[0032] Additionally, the side 12 can form a finger contact area 121 for the user's fingers to touch, and the fingerprint sensor 21 can be disposed in the finger contact area 121. When the fingerprint sensor 21 is triggered, it can identify the user's fingerprint, so that subsequent fingerprint analysis can be used to determine whether the user meets the requirements for using electronic cigarettes, such as determining whether the user is an adult.
[0033] In this embodiment, the width of the side 12 of the housing 10 is smaller than the width of the front 11, so that the housing 10 has a flat structure. The fingerprint sensor 21 is disposed on the side 12 of the housing 10. Compared with the method of disposing of the fingerprint sensor 21 on the front 11, this embodiment can reduce the space occupied by the fingerprint sensor 21 on the surface of the electronic cigarette housing 10, which is conducive to the miniaturization design of the electronic cigarette, making the electronic cigarette easier to carry, and also helps to improve the appearance performance of the electronic cigarette. Furthermore, since the fingerprint sensor 21 occupies a small area, the probability of accidental touch is reduced, so that the electronic cigarette is no longer accidentally activated, thereby helping to reduce the power consumption of the electronic cigarette.
[0034] In some embodiments, the fingerprint sensor 21 can be an elongated fingerprint sensor 21. Exemplarily, the fingerprint sensor 21 can be a fingerprint sensor with an ultra-narrow width side. Compared with a circular or square fingerprint sensor 21, the fingerprint sensor 21 in this embodiment has a smaller width and is located on the side 12 of the housing 10, which helps to reduce the space occupied by the fingerprint sensor 21 inside and outside the housing 10, and further improves the miniaturization of the electronic cigarette.
[0035] In some embodiments, the housing 10 can be a cylindrical structure with a rectangular cross-section, such that the thickness of the housing 10 is smaller than its length and width.
[0036] In other embodiments, the housing 10 may also be an elliptical cylindrical structure or other shapes, which are not specifically limited here.
[0037] refer to Figure 3 In some embodiments, the electronic cigarette may further include a button 22, which is disposed in the housing 10 and located inside the fingerprint sensor 21, and is used for electrical connection with the mainboard of the electronic cigarette. Based on this, when the finger contact area 121 is pressed, the fingerprint sensor 21 can transmit the force to the button 22, triggering the button 22, thereby enabling corresponding operations on the electronic cigarette to achieve the corresponding functions. Furthermore, the fingerprint sensor 21 can be electrically connected to the mainboard via a flexible circuit board 24, and the button 22 can also be electrically connected to the mainboard, thus enabling signal transmission between the fingerprint sensor 21 and the button 22 and the mainboard respectively.
[0038] Optionally, button 22 may have an appropriate travel, such as 0.3mm ± 0.05mm, to provide clear tactile feedback.
[0039] In this embodiment of the electronic cigarette, the fingerprint sensor 21 and the button 22 are integrated together to form an integrated module 20. The fingerprint sensor 21 can realize the fingerprint recognition function, and the button 22 can realize the operation of the electronic cigarette. Furthermore, integrating the fingerprint sensor 21 and the button 22 on the side 12 of the housing 10 can reduce the space occupied on the surface of the housing 10, thereby helping to reduce the size of the electronic cigarette and realize the miniaturization design of the electronic cigarette.
[0040] In addition, compared to the fingerprint sensor 21 and button 22 being independently set on the surface of the housing 10, integrating the fingerprint sensor 21 and button 22 on the side 12 of the housing 10 can make the appearance of the housing 10 more concise, which is conducive to improving the aesthetics of the electronic cigarette. Furthermore, since the area occupied on the surface of the housing 10 is reduced, the probability of accidental touch can be reduced, thereby alleviating the problem of energy waste caused by accidental activation of the electronic cigarette.
[0041] In addition, the fingerprint sensor 21 and the button 22 are integrated together in this embodiment, which can alleviate the problem of complex structure caused by separately setting the fingerprint module and physical button on the housing 10. Furthermore, different functions can be achieved to alleviate the problem of the fingerprint module having a single function.
[0042] Integrating the fingerprint sensor 21 and button 22 on the side 12 of the housing 10 can save space on the front 11 of the housing 10 occupied by the user interface, making it easier to integrate the integrated module 20 onto the housing 10. Furthermore, the integrated module 20 on the side 12 is more ergonomic and makes operation more convenient.
[0043] Optionally, such as Figures 5 to 7 As shown, the finger contact area 121 can be provided with a mounting hole 122, and the button 22 can be disposed in the mounting hole 122. In this way, the button 22 can be provided with installation space to realize the installation of the button 22 and ensure the stability of the button 22.
[0044] refer to Figure 6 and Figure 7 In some embodiments, the housing 10 may further include a limiting member 14, which is detachably disposed in the mounting hole 122 to facilitate the installation and removal of the limiting member 14; and the limiting member 14 may be provided with a through hole 141, the button 22 is disposed inside the housing 10, and the end of the button 22 protrudes outside the housing 10 through the through hole 141. Based on this, the end of the button 22 protruding outside the housing 10 can contact the fingerprint sensor 21 and be subjected to the squeezing action of the fingerprint sensor 21.
[0045] Based on the above settings, the button 22 can be limited by the limiting member 14, and the detachable installation of the limiting member 14 facilitates the maintenance or replacement of the button 22.
[0046] refer to Figure 6 In some embodiments, a frame 13 may be provided inside the housing 10. The frame 13 is fastened to the inner surface of the side 12 of the housing 10. The end of the button 22 located inside the housing 10 abuts against the frame 13. In this way, the frame 13 can limit the end of the button 22 to ensure the stability of the button 22 under the pressure.
[0047] refer to Figures 1 to 3 In some embodiments, the electronic cigarette may also include a flexible circuit board 24, which may be disposed within the housing 10. One side of the flexible circuit board 24 is connected to the fingerprint sensor 21, and the other side of the flexible circuit board 24 is used for electrical connection to the motherboard. In this way, the fingerprint sensor 21 can be electrically connected to the motherboard through the flexible circuit board 24 to facilitate the transmission of information between the fingerprint sensor 21 and the motherboard.
[0048] The flexible circuit board 24 may include a first connecting portion 241, a second connecting portion 242, and a bending portion 243. The bending portion 243 is connected between the first connecting portion 241 and the second connecting portion 242 so that the first connecting portion 241 and the second connecting portion 242 can move relative to each other through the bending portion 243, thereby changing the shape of the flexible circuit board 24. In addition, signals can also be transmitted between the first connecting portion 241 and the second connecting portion 242 through the bending portion 243.
[0049] The first connecting part 241 is connected to the fingerprint sensor 21, and the second connecting part 242 is connected to the button 22. In addition, the second connecting part 242 is also used to electrically connect to the control module of the electronic cigarette (e.g., the microprocessor module 60 described below) so as to transmit signals between the fingerprint sensor 21 and the control module.
[0050] In addition, the fingerprint sensor 21, the first connecting part 241, the second connecting part 242 and the button 22 can be stacked in sequence. In this way, while meeting the signal transmission requirements, the layout space of these components in the housing 10 can be optimized, thereby improving the space utilization rate of the housing 10.
[0051] refer to Figure 2 and Figure 3 In some embodiments, the electronic cigarette may further include a reinforcing layer 23, which may be disposed within the housing 10 and stacked between the fingerprint sensor 21 and the button 22. Based on this arrangement, when the user applies pressure to the fingerprint sensor 21 by pressing the finger contact area 121, the reinforcing layer 23 can provide support for the fingerprint sensor 21, thereby effectively alleviating the problem of deformation or even breakage of the fingerprint sensor 21 due to prolonged pressure, and thus improving the service life of the fingerprint sensor 21.
[0052] In addition, when the fingerprint sensor 21 receives a pressing force, it can be transmitted to the reinforcement layer 23 and then to the button 22 to trigger the button 22.
[0053] Optionally, the reinforcing layer 23 can be a metal reinforcing sheet, or other forms, which are not specifically limited here.
[0054] Furthermore, the fingerprint sensor 21, the first connecting part 241, the reinforcing layer 23, the second connecting part 242, and the button 22 can be stacked sequentially. In this way, while meeting the signal transmission requirements, the layout space of these components within the housing 10 can be optimized, thereby improving the space utilization rate within the housing 10.
[0055] Reference Figure 4 and Figure 8 In some embodiments, the electronic cigarette may further include a feedback module 30, which is disposed in the housing 10 and used for electrical connection with the motherboard. Optionally, the feedback module 30 may be disposed on the inner side of the housing 10 or on the outer side of the housing 10, or a portion of the structure of the feedback module 30 may be disposed on the inner side of the housing 10 and another portion on the outer side of the housing 10, as long as it can provide feedback information to the user, the specific arrangement is not limited.
[0056] Optionally, the feedback module 30 can be electrically connected to the microprocessor module 60 on the motherboard to achieve signal transmission.
[0057] Optionally, the feedback module 30 may include at least one of an LED light, a display screen, a vibrator, and a buzzer. Based on this, the feedback module 30 can provide the user with information about the electronic cigarette through sound and light.
[0058] refer to Figure 8 In some embodiments, the electronic cigarette may also include a power management module 50, which is disposed inside the housing 10 and is used to electrically connect to the motherboard so as to manage the power of the electronic cigarette through the power management module 50, thereby improving the battery life of the electronic cigarette.
[0059] Optionally, a microprocessor module 60 may be provided on the motherboard. Both the power management module 50 and the microprocessor module 60 may be located inside the housing 10. The power management module 50 and the integrated module 20 may be electrically connected to the microprocessor module 60 respectively, so as to control the operation of the power management module 50 through the microprocessor module 60, thereby realizing the control of the power of the electronic cigarette.
[0060] Continue to refer to Figure 8In some embodiments, the electronic cigarette may also include a heating module 40, which is disposed within the housing 10 and is used to electrically connect to the motherboard to realize the basic functions of the electronic cigarette.
[0061] Optionally, a microprocessor module 60 may be provided on the motherboard, and the heating module 40 and the integrated module 20 may be electrically connected to the microprocessor module 60 respectively, so that the heating module 40 can be controlled by the microprocessor module 60 to perform heating, thereby realizing the basic functions of the electronic cigarette.
[0062] In some specific embodiments, the hardware control structure of the electronic cigarette may include a microprocessor module 60, a power management module 50, a heating module 40, an integration module 20, and a feedback module 30. The power management module 50, heating module 40, integration module 20, and feedback module 30 are all electrically connected to the microprocessor module 60. The microprocessor module 60, as the overall control unit of the electronic cigarette, can realize functions such as user information storage, fingerprint recognition, and heating management; the power management module 50 supplies power and manages the energy of each module; the heating module 40 is used to heat the e-liquid and other atomizing substrates containing nicotine; and the feedback module 30 is used to provide real-time feedback on the status of the electronic cigarette during operation, such as heating status, battery level, and fingerprint recognition status.
[0063] This application also discloses a method for identifying electronic cigarettes, used to identify the identity information of electronic cigarette users, where the electronic cigarette is the aforementioned electronic cigarette. The disclosed identification method includes:
[0064] When the finger contact area 121 is pressed, it receives the user's fingerprint information and the pressing signal;
[0065] Check whether the identified fingerprint information matches the preset fingerprint information;
[0066] If the fingerprint information matches the preset fingerprint information, the heating function of the electronic cigarette will be activated.
[0067] Based on the above steps, the user's fingerprint can be identified and compared before the e-cigarette is activated. When the fingerprints match, it indicates that the user meets the usage requirements. In this case, the e-cigarette can perform its basic functions for the user to use. When the fingerprints do not match, it indicates that the user does not meet the usage requirements. In this case, the e-cigarette cannot perform its basic functions, thus effectively preventing users who do not meet the usage requirements from using the e-cigarette.
[0068] Optionally, the system receives the user's fingerprint information and pressure signal, including:
[0069] If the pressing time meets the first condition, control the activation of the electronic cigarette and / or detect the electronic cigarette's battery level.
[0070] If the pressing time meets the second condition, control the recognition of fingerprint information.
[0071] Optionally, the first condition can refer to a time less than a preset time, and the second condition can refer to a time greater than or equal to a preset time. Other forms are also possible, but are not specifically limited here.
[0072] For example, the preset time can be 0.5s, but of course, it can also be other values, which are not specifically limited here.
[0073] Specifically, when the pressing time is less than 0.5 seconds, it can be defined as a short press. At this time, it can control the electronic cigarette to wake up or control the electronic cigarette to detect the battery information so that the user can understand the usage status of the electronic cigarette.
[0074] When the pressing time is greater than or equal to 0.5 seconds, it can be defined as continuous pressing. At this time, the fingerprint sensor 21 can be activated so that the fingerprint sensor 21 can identify the user's fingerprint.
[0075] Optionally, the electronic cigarette may include a microprocessor module 60, an integrated module 20, and a power management module 50, wherein the integrated module 20 includes a fingerprint sensor 21 and a button 22;
[0076] If no press signal is received, the microprocessor module 60 is in standby mode and controls the fingerprint sensor 21 to be in a power-off state.
[0077] If the pressing time meets the first condition, the microprocessor module 60 switches to the wake-up state and controls the power management module 50 to detect the power information;
[0078] If the pressing time meets the second condition, the microprocessor module 60 controls the fingerprint sensor 21 to recognize the fingerprint information, and controls the fingerprint sensor 21 to switch to the power-off state after the fingerprint information matching is completed.
[0079] The electronic cigarette in this embodiment has a three-level power consumption management mechanism, including:
[0080] Ultra-low power consumption mode: When button 22 is not pressed, the control microprocessor module 60 is in standby mode, and the microprocessor module 60 controls the fingerprint sensor 21 to be in a power-off state. At this time, the power consumption of the microprocessor module 60 and the fingerprint sensor 21 is low, which is beneficial to improving the battery life of the electronic cigarette.
[0081] Low power mode: When the finger touches the contact area 121, the pressing time of the button 22 is less than a preset time, such as less than 0.5s. At this time, the microprocessor module 60 is woken up and controls the power management module 50 to detect power information and other functions, and controls the fingerprint sensor 21 to remain in a power-off state, thereby reducing power consumption.
[0082] Normal power consumption mode: Press and hold the finger contact area 121, so that the pressing time of the button 22 is greater than or equal to the preset time, such as greater than or equal to 0.5s. At this time, the microprocessor module 60 controls the fingerprint sensor 21 to scan and recognize the user's fingerprint, and sends the recognized fingerprint information to the microprocessor module 60 so that the microprocessor module 60 can compare the recognized fingerprint information with the preset fingerprint information.
[0083] When the detected fingerprint information matches the preset fingerprint information, the microprocessor module 60 determines that the user meets the usage requirements and allows the user to use the electronic cigarette; when the detected fingerprint information does not match the preset fingerprint information, the microprocessor module 60 determines that the user does not meet the usage requirements and the user cannot use the electronic cigarette.
[0084] After fingerprint recognition, the microprocessor module 60 controls the fingerprint sensor 21 to automatically switch to a low-power mode, which can prevent the fingerprint sensor 21 from being in a recognition state for a long time, thus reducing the power consumption of the e-cigarette and extending its battery life.
[0085] Optionally, identifying whether the fingerprint information matches preset fingerprint information includes:
[0086] If the fingerprint information matches the preset information, the system will display a message indicating successful fingerprint recognition.
[0087] If the fingerprint information does not match the preset fingerprint information, the system will enter a time-limited lock mode and display a fingerprint recognition failure message.
[0088] Specifically, if the fingerprint information does not match the preset fingerprint information, that is, if the fingerprint recognition fails, a 3-second input blocking is activated to prevent the fingerprint sensor 21 from being triggered repeatedly.
[0089] In addition, the recognition status can be fed back through the feedback module 30 to provide feedback to the user. For example, the feedback module 30 can use an LED light; after successful fingerprint recognition, the LED light can be solid green; after fingerprint recognition fails, the LED light can be red and flash three times.
[0090] In this embodiment of the application, the fingerprint recognition process is as follows:
[0091] When the user presses the integrated module 20, triggering button 22, the microprocessor module 60 is activated.
[0092] If the pressing time is too short and does not reach the preset time (e.g., less than 0.5s), the fingerprint sensor 21 will not be triggered, and actions such as power detection will not be performed.
[0093] If the pressing time exceeds the preset time (e.g., greater than or equal to 0.5s), the microprocessor module 60 controls the fingerprint sensor 21 to start for fingerprint scanning and recognition.
[0094] If the identified fingerprint information matches the preset information, the preset function is executed, such as informing the user of the successful match through LED lights, vibrators, displays, buzzers, etc.
[0095] If the detected fingerprint information does not match the preset information, a time-limited lock is entered (e.g., lock for 3 seconds). At this time, the microprocessor module 60 blocks the input information of the button 22 to avoid continuous false triggering.
[0096] In summary, the electronic cigarette in this embodiment integrates a fingerprint sensor 21 and a button 22 on the side 12 of the housing 10, thereby achieving a miniaturized design while providing fingerprint recognition and operation functions to prevent minors from using it; the fingerprint function can be activated by the button 22, preventing the fingerprint sensor 21 from being in working state when in standby mode, reducing the overall power consumption of the electronic cigarette when in standby mode, and helping to extend the battery life of the electronic cigarette.
