[0002] The development of technology has had a great impact on all aspects. In recent years, with the improvement of people's health awareness, electronic cigarettes have become popular among people because they do not contain harmful components such as tar and suspended particles. In addition to being harmless to physical health, the e-liquid of electronic cigarettes can be flavored with different ingredients, and users can choose the flavor of the e-liquid according to their own preferences. Therefore, smoking electronic cigarettes is gradually becoming a trend.

[0003] Electronic cigarettes need to replace cartridges, which are consumables and the key to the long-term profitability of electronic cigarette manufacturers. However, once a certain brand of electronic cigarette becomes a hit in the market, a large number of counterfeit electronic cigarettes and compatible cartridges will appear in the electronic cigarette market, resulting in a decline in the sales volume of genuine cartridges. Moreover, a large number of counterfeits will impact the brand and image of the genuine product. Counterfeit and shoddy electronic cigarettes and cartridges are passed off as genuine in the electronic cigarette market, and it is difficult for consumers to distinguish between counterfeit cartridges and genuine cartridges. Inhaling e-liquid with unknown ingredients will harm consumers' physical health. In the prior art, electronic cigarettes do not have anti-counterfeiting technology or the anti-counterfeiting technology is weak, and the anti-counterfeiting technology is easily cracked, resulting in the technical problem that cartridges are easily forged by illegal manufacturers.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after without special explanation.

[0041] Next, in conjunction with Figures 1 - 6 Describe the e-cigarette rod, cartridge, device, and control method of the present invention.

[0042] Figure 1 The following shows a flowchart of the e-cigarette control method provided by an embodiment of the present invention. Figure 2 This is a schematic structural diagram of an e-cigarette rod provided by an embodiment of the present invention. The e-cigarette rod includes a controller 201, a power supply 202, and a decryption unit 203. After an e-cigarette cartridge is inserted into the e-cigarette rod:

[0043] The controller 201 confirms whether there is a communication link between the cartridge and the rod. If there is a communication link, a preset key is sent to the cartridge;

[0044] If the controller 201 receives the serial number encrypted using the key fed back by the cartridge, the decryption unit 203 is triggered to decrypt the encrypted serial number using the key, and it is determined whether the decrypted serial number is a legal serial number. When the serial number is legal, after sensing the user's sucking action, the power supply 202 is triggered to supply power to the atomizer in the cartridge to atomize the e-liquid in the cartridge. When the serial number is illegal, the power supply 202 is prohibited from supplying power to the atomizer in the cartridge;

[0045] If the controller 201 confirms that there is no communication link between the cartridge and the rod or does not receive the serial number encrypted with the key and fed back by the cartridge, the power supply 202 is prohibited from supplying power to the atomizer in the cartridge.

[0046] The e-cigarette rod includes a controller 201, a power supply 202, and a decryption unit 203. Exemplarily, the controller 201 is a microcontroller unit (MCU). The MCU is also known as a single-chip microcomputer or a microcontroller. It appropriately reduces the frequency and specifications of the central processing unit and integrates peripheral interfaces such as memory, counter, USB, A / D conversion, UART, PLC, and DMA on a single chip to form a chip-level computer for different combinations of control in different application scenarios. The power supply 202 is used to supply power to the rod and the cartridge of the e-cigarette. The decryption unit 203 is used to decrypt the encrypted information returned by the cartridge to obtain the serial number carried on the cartridge for anti-counterfeiting.

[0047] The following describes the e-cigarette control method of the present invention according to Figure 1 the flowchart of the e-cigarette control method in

[0048] Step 101: The cartridge is inserted into the rod.

[0049] Exemplarily, when a user smokes an e-cigarette, a cartridge needs to be configured for the e-cigarette rod. Thus, when a user uses an e-cigarette, the e-cigarette needs to detect whether a cartridge is inserted into the e-cigarette rod. Only when the controller of the rod detects that the cartridge is inserted into the rod can the e-cigarette trigger the authentication operation of the cartridge.

[0050] In the circuit of the cartridge, there is a heating wire on the atomizer for heating the e-liquid. Among them, the resistance of the heating wire is a low resistance. After the cartridge is installed on the rod, the circuit on the controller 201 of the e-cigarette will change due to the access of the heating wire with a low resistance. When the controller 201 detects the access of a low resistance in the circuit, the circuit will trigger a change in the level to generate a level signal. When this level signal appears in the circuit, the controller 201 determines that the cartridge is installed on the e-cigarette rod.

[0051] Step 102: The controller 201 confirms whether there is a communication link between the cartridge and the rod.

[0052] Exemplarily, if the cartridge is a genuine cartridge, a communication link for verifying the authenticity of the cartridge can be established between the cartridge and the smoking rod, and the data is transmitted in this communication link to verify whether there is correct anti-counterfeiting information on the cartridge. After the controller 201 detects that the cartridge is inserted into the smoking rod, the controller 201 needs to determine whether there is a communication link between the cartridge and the smoking rod. When there is a communication link between the cartridge and the smoking rod, the method in step 103 is executed; when there is no communication link between the cartridge and the smoking rod, the method in step 108 is executed.

[0053] Step 103: The controller 201 sends a preset key to the cartridge.

[0054] Exemplarily, after the controller 201 confirms that a communication link is established between the cartridge and the smoking rod, in order to verify whether there is a correct anti-counterfeiting serial number on the cartridge, the controller 201 sends a preset key to the cartridge, where the key is used for the cartridge to encrypt the serial number on its own storage space.

[0055] If the cartridge is genuine, an encryption chip is provided inside the cartridge, and a serial number for anti-counterfeiting is stored on the storage space of the chip. When the cartridge receives the key sent by the controller 201, it parses the key to obtain the encryption algorithm corresponding to the key. Among them, there are various types of encryption algorithms, and the type of encryption algorithm used can be determined according to actual needs in specific applications. After the cartridge determines the encryption algorithm, it encrypts the serial number according to the encryption algorithm to obtain an encrypted serial number. After the cartridge generates the encrypted serial number, it sends it to the controller 201 of the smoking rod so that the controller 201 can verify the authenticity of the serial number.

[0056] Step 104: The controller 201 determines whether it receives the serial number encrypted with the key fed back by the cartridge.

[0057] Exemplarily, when the cartridge newly loaded into the smoking rod is genuine, the cartridge will generate an encrypted serial number according to the key and the serial number, and send the encrypted serial number to the controller 201 of the smoking rod through the communication link. If the cartridge is a counterfeit, there may be no encryption chip in the cartridge; or the encryption chip in the counterfeit cartridge cannot establish a communication link with the controller 201 of the smoking rod; it is also possible that the cartridge is a highly imitated counterfeit cartridge, and a counterfeit serial number is also stored on the storage space of the highly imitated cartridge. The highly imitated cartridge can generate a counterfeit encrypted serial number according to the counterfeit serial number and the key sent by the controller 201, and send the counterfeit encrypted serial number to the controller 201 of the smoking rod.

[0058] In order to obtain the serial number that can prove that the cigarette cartridge is genuine, the controller 201 determines whether it has received the serial number encrypted using the key fed back by the cigarette cartridge. If the cigarette rod receives the serial number encrypted using the key fed back by the cigarette cartridge, the method in step 105 is continued to be executed; if the cigarette rod does not receive the serial number encrypted using the key fed back by the cigarette cartridge, the method in step 108 is directly executed.

[0059] Step 105: The controller 201 triggers the decryption unit 203 to decrypt the encrypted serial number using the key.

[0060] Exemplarily, after the controller 201 of the cigarette rod receives the encrypted serial number sent by the cigarette cartridge, the decryption unit 203 decrypts the encrypted serial number according to the key, wherein the decryption process of the cigarette rod is the reverse process of the encryption process of the cigarette cartridge. Specifically, the decryption unit 203 performs a decryption operation on the encrypted serial number according to the decryption algorithm corresponding to the key to obtain the real serial number of the cigarette cartridge.

[0061] Step 106: The controller 201 determines whether the serial number is a legal serial number.

[0062] Exemplarily, the serial number is the identity information of each cigarette cartridge, and the serial number of the genuine cigarette cartridge is uniquely determined, wherein the manufacturer will generate the serial number based on the relevant information of the cigarette cartridge. After the decryption unit 203 of the cigarette rod parses the serial number, the controller 201 calculates the estimated serial number based on the information of the cigarette cartridge, and verifies it with the parsed serial number. If the two serial numbers are consistent, it means that the serial number is correct, and it can be determined that the verified cigarette cartridge is genuine, and the method in step 107 is continued; if the verification is inconsistent, it means that the cigarette cartridge is a counterfeit cigarette cartridge, and the method in step 108 is directly executed.

[0063] Step 107 , after sensing the user's puffing action, the controller 201 triggers the power supply 202 to supply power to the atomizer in the cigarette cartridge to atomize the cigarette oil in the cigarette cartridge.

[0064] Exemplarily, when the controller 201 of the cigarette rod verifies that the serial number of the cigarette cartridge is a serial number that meets the standards, it is determined that the cigarette cartridge is a genuine cigarette cartridge, and the cigarette cartridge changes from a locked state to an unlocked state. The controller 201 turns on the cigarette lighting function, and the controller 201 connects the power supply 202 to the cigarette cartridge. The power supply 202 supplies power to the heating wire in the atomizer of the cigarette cartridge, and the heating wire is heated to evaporate the cigarette oil so that the user can use the electronic cigarette normally.

[0065] Step 108: The controller 201 prohibits the power supply 202 from supplying power to the atomizer in the cigarette cartridge.

[0066] Exemplarily, during the process of the cigarette rod of the electronic cigarette verifying the authenticity of the cartridge, when any one of the following three situations described below occurs, it indicates that the cartridge is a counterfeit. Once it is determined that the cartridge is a counterfeit, the controller 201 prohibits the power supply 202 from supplying power to the atomizer in the cartridge.

[0067] The three situations in which it can be determined that the cartridge is a counterfeit are as follows: First, the controller 201 confirms that there is no communication link between the cartridge and the cigarette rod; Second, the controller 201 does not receive the serial number encrypted with the usage key feedback from the cartridge; Third, the controller 201 determines that the parsed serial number is an illegal serial number.

[0068] When the controller 201 verifies that the cartridge is a counterfeit, the cartridge is set to a locked state to invalidate the cigarette lighting function, and the power supply 202 does not supply power to the atomizer in the cartridge. Once the cartridge is locked, no matter how the user adjusts the electronic cigarette, the cartridge will not supply power to the atomizer of the cartridge.

[0069] Through the technical solution of the present invention, when the cartridge of the electronic cigarette is inserted into the cigarette rod, if the cartridge is genuine, a communication link will be formed between the cartridge and the cigarette rod, and the cartridge will encrypt the serial number on the cartridge according to the key sent by the controller of the electronic cigarette. The controller decrypts and verifies the encrypted serial number returned by the cartridge. When the serial number is legal, the power supply of the cigarette rod supplies power to the atomizer of the cartridge so that the user can use the electronic cigarette normally. During this process, the serial number on the cartridge cannot be directly read by the electronic cigarette. The serial number is numbered according to a preset numbering rule and is difficult to be randomly copied. The ciphertext transmitted between the cigarette rod and the cartridge of the electronic cigarette is encrypted. The controller on the cigarette rod decrypts the encrypted serial number and determines the authenticity of the cartridge by verifying whether the serial number is correct. Thus, through the electronic cigarette control method of the present invention, the serial number of the cartridge is not easily stolen, the data transmitted through the communication link between the cigarette rod and the cartridge is encrypted data, and the encryption technology is difficult to be cracked by illegal manufacturers, improving the anti-counterfeiting performance of the electronic cigarette cartridge.

[0070] As Figure 3 shown, based on the inventive concept of an electronic cigarette rod in an embodiment of the present invention, the present invention also provides an electronic cigarette cartridge, characterized in that the cartridge includes e-liquid 301, an atomizer 302, and an encryption unit 303. After the cartridge is inserted into the cigarette rod, the encryption unit receives the key sent by the cigarette rod, uses the key to encrypt the pre-stored serial number of the cartridge, and transmits the encrypted serial number back to the cigarette rod to trigger the cigarette rod to supply power to the atomizer when the serial number is legal.

[0071] Exemplarily, there is e-liquid 301 on the cartridge, and different flavors can be added to the e-liquid for users to choose. The atomizer 301 has a heating wire with a low resistance. When the heating wire is powered on, the heating wire generates heat to evaporate the e-liquid for the user to smoke. The encryption unit 303 is used to encrypt the serial number on the storage space of the cartridge according to the key.

[0072] An encryption chip is provided on the cartridge. Anti-counterfeiting of the cartridge chip is a relatively novel brand authentication method. The controller on the electronic cigarette verifies the serial number on the encryption chip of the cartridge. If the verification passes, the cartridge is determined to be a genuine cartridge; if the verification fails, the cartridge is determined to be a non-genuine cartridge.

[0073] As Figure 4 shown, based on the inventive concept of an electronic cigarette rod in an embodiment of the present invention, the present invention also provides an electronic cigarette device, characterized in that the electronic cigarette device includes a cigarette rod 401 and a cartridge 402, the cartridge 402 is electrically connected to the cigarette rod 401 through a plug-in structure 403, the cartridge 402 includes e-liquid 4021, an atomizer 4022 and an encryption unit 4023, and the cigarette rod 401 includes a controller 4011, a power supply 4012 and a decryption unit 4013. Among them, after the cartridge 402 is inserted into the cigarette rod 401:

[0074] The controller 4011 powers on the encryption unit 4023 and sends a preset key to the encryption unit 4023;

[0075] The encryption unit 4023 uses the key to encrypt the pre-stored serial number of the cartridge 402 and transmits the encrypted serial number back to the controller 4011;

[0076] The controller 4011 triggers the decryption unit 4013 to use the key to decrypt the encrypted serial number and determines whether the decrypted serial number is a legal serial number;

[0077] If the serial number is legal, after sensing the user's sucking action, the controller 4011 triggers the power supply 4012 to supply power to the atomizer 4022 to atomize the e-liquid 4021. If the serial number is illegal, the power supply 4012 is prohibited from supplying power to the atomizer 4021.

[0078] Further, the plug-in structure 403 includes a power supply circuit and a communication link between the cartridge 402 and the cigarette rod 401. Among them, the power supply circuit and the communication link share the same single wire, and the communication link is a single-wire bidirectional communication link.

[0079] Exemplarily, when the cartridge 402 is installed on the stem 401 of the electronic cigarette, the cartridge 402 is electrically connected to the stem 401 through a plug-in structure. A circuit line that can transmit both current and communication signals is integrated on the plug-in structure, that is, the power supply circuit and the communication link between the cartridge 402 and the stem 401 share the same single wire. Bidirectional data transmission is carried out between the controller 4011 of the stem 401 and the encryption unit 4023 of the cartridge 402 through a single-wire communication link, and the single-wire communication protocol is used for the communication link. Among them, there are various types of single-wire communication protocols, and the single-wire communication protocol used can be determined according to actual needs in specific applications.

[0080] Further, the stem 401 further includes a pneumatic sensor for sensing the user's sucking action.

[0081] Exemplarily, when the stem senses the user's sucking action, the controller 4011 regulates the power supply 4012 to heat the atomizer 4022 for the user to use the e-liquid 4021.

[0082] Further, the controller 4011 determines whether the decrypted serial number is a legal serial number based on a preset serial number coding rule.

[0083] Exemplarily, the manufacturer numbers the cartridge 402 according to the factory information of the cartridge 402 and a preset numbering rule to generate a serial number. This preset numbering rule is confidential information and is specifically related to information such as the device model, production time, batch, and flavor of the cartridge. After the electronic cigarette parses out the serial number, it calculates the serial number according to the information of the cartridge 402 and the preset numbering rule, and verifies it with the parsed serial number. If the verification is consistent, it means that the serial number is correct and the cartridge 402 is a genuine product. If the verification is inconsistent, it means that the cartridge 402 is a counterfeit product.

[0084] Further, the power supply is a battery.

[0085] As Figure 5 shown, based on the inventive concept of a stem of an electronic cigarette in an embodiment of the present invention, the present invention further provides a method for controlling an electronic cigarette cartridge for an electronic cigarette stem, characterized in that the method includes:

[0086] Step 501: After the cartridge is inserted into the stem, confirm whether there is a communication link between the cartridge and the stem. If there is a communication link, send a preset key to the cartridge;

[0087] Step 502: If the encrypted serial number fed back by the cartridge using the key is received, decrypt the encrypted serial number using the key, and determine whether the decrypted serial number is a legitimate serial number. If the serial number is legitimate, trigger the power supply in the cigarette rod to supply power to the atomizer in the cartridge after detecting the user's puffing action to atomize the e-liquid in the cartridge. If the serial number is illegal, prohibit the power supply from supplying power to the atomizer in the cartridge;

[0088] Step 503: If it is confirmed that there is no communication link between the cartridge and the cigarette rod or the encrypted serial number fed back by the cartridge using the key is not received, prohibit the power supply from supplying power to the atomizer in the cartridge.

[0089] As Figure 6 shown, based on the inventive concept of an e-cigarette rod in an embodiment of the present invention, the present invention also provides an e-cigarette control method for an e-cigarette device. The e-cigarette device includes a cigarette rod and a cartridge electrically connected to each other through a plug-in structure. The method is characterized in that the method includes:

[0090] Step 601: After the cartridge is inserted into the cigarette rod, the cigarette rod sends a preset key to the cartridge;

[0091] Step 602: The cartridge encrypts the pre-stored serial number of the cartridge using the key and transmits the encrypted serial number back to the cigarette rod;

[0092] Step 603: The cigarette rod decrypts the encrypted serial number using the key and determines whether the decrypted serial number is a legitimate serial number;

[0093] Step 604: If the serial number is legitimate, the cigarette rod supplies power to the atomizer in the cartridge after detecting the user's puffing action to atomize the e-liquid in the cartridge;

[0094] Step 605: If the serial number is illegal, prohibit power supply to the atomizer.

[0095] According to another aspect of the present invention, the present invention also provides a storage medium in which multiple instructions are stored. The instructions are suitable for being loaded by a processor to execute any of the above-described authentication methods for e-cigarette cartridges.

[0096] In summary, although the present invention has been disclosed above with preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is subject to the scope defined by the claims.
