Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

In the existing electronic cigarette device, basically, a mode of packaging tobacco tar by using tobacco cartridges is adopted, and the tobacco cartridges are sold by manufacturers of electronic cigarettes. However, the cartridges are easy to imitate, even if some cartridges are made of DIY, the source of tobacco tar in the imitated cartridges is also five-flower eight-door, so that the quality of the imitated cartridges is difficult to ensure for merchants, users trade and put the imitated cartridges into tobacco stems for use, the imitated cartridges may harm bodies, and the imitated cartridges also affect the reputation and legal rights of the merchants.

For this purpose, referring to fig. 1, the invention provides a cartridge encryption anti-counterfeiting chip, the electronic cigarette includes a cartridge and a tobacco stem, the cartridge encryption anti-counterfeiting chip is disposed in the cartridge, the cartridge and the tobacco stem are connected in a pluggable manner, and in an embodiment of the invention, the cartridge encryption anti-counterfeiting chip includes:

the processing unit 10 is electrically connected with the signal transmission end;

an encryption operation unit 20, the encryption operation unit 20 being electrically connected to the processing unit 10;

The storage unit 30 is electrically connected with the encryption operation unit 20 and the processing unit 10 respectively, and the storage unit 30 stores a factory code in advance; the factory code of each cigarette bullet encryption anti-counterfeiting chip is different;

the processing unit 10 is configured to receive the client code and output the client code to the encryption operation unit 20, so that the encryption operation unit 20 performs operation according to a preset operation rule to obtain a first operation value, and compares the first operation value with the preset first operation value;

the processing unit 10 is further configured to, when it is determined that the first operation value is consistent with the preset first operation value, control the encryption operation unit 20 to perform encryption encoding on the client code and the factory code according to a preset encryption encoding rule to form an encryption encoding;

the processing unit 10 is further configured to control the encryption operation unit 20 to convert the encryption code into a code hopping code according to a code hopping rule that the tobacco bounces are transferred to the tobacco stem when the tobacco bounces are plugged and unplugged last time, and control the encryption operation unit 20 to randomly generate the code hopping rule and transfer the code hopping code and the code hopping rule randomly generated this time back to the tobacco stem together, so that the tobacco stem restores the code hopping code to the encryption code according to the code hopping rule that the tobacco bounces are transferred to the tobacco stem when the tobacco bounces last time are plugged and restore the encryption code, and then judge whether the tobacco bounces are true or false according to the encryption code and the preset decoding operation rule, and store the code hopping code and the code hopping rule randomly generated this time when the tobacco bounces are true.

In this embodiment, the cartridge encryption anti-counterfeiting chip may include a package housing and a pin, the processing unit 10, the encryption operation unit and the storage unit 30 may be disposed on a circuit board and disposed in the package housing, the signal transmission end may be a metal pin of the cartridge encryption anti-counterfeiting chip, one end is electrically connected with the processing unit 10 on the circuit board, and the other end extends out of the package housing to be connected with a peripheral circuit. The processing unit 10 may be implemented by a main control chip, for example, an MCU, a DSP (Digital Signal Process, a digital signal processing chip), an FPGA (Field Programmable Gate Array, a programmable gate array chip), etc., the storage unit 30 may be implemented by a nonvolatile memory, for example, an EPROM memory, an EEPROM memory, a Flash memory, etc., and the encryption operation unit 20 may be implemented by a logic device.

It should be understood that in practical application, the chip producer may provide the electronic cigarette producer with the encryption anti-counterfeiting chip of the cartridge of the invention and also provide the electronic cigarette producer with the programming tool, so that the user may set the basic code in the programming tool according to the specification, and then the programming tool generates a plurality of different client codes according to the preset checking rules, so as to ensure that the tobacco rods produced by each electronic cigarette manufacturer are different. The client code generated by the programming tool may also include the time at which the client code was currently generated and the code of the current e-cigarette manufacturer (which may be preset by the chip manufacturer). In addition, the programming tool can also realize the verification of the data transmitted by the cartridge, and can also enable a user to add other auxiliary programs in the programming tool and burn the auxiliary programs into the tobacco stem for storage.

In this embodiment, when a cartridge is inserted into a tobacco rod, the tobacco rod detects that the cartridge is inserted into the tobacco rod and outputs a client code, at this time, the processing unit 10 receives the client code output by the tobacco rod and outputs the client code to the encryption operation unit 20, and controls the encryption operation unit 20 to operate according to a preset operation rule (the preset operation rule is set by a chip manufacturer) to obtain a first operation value, and compares the first operation value with the preset first operation value, for example, according to the preset operation rule, the client code is added from the first position to the last position to be 100, if the client code cannot be received or the sum of the client codes added together is not 100, the current tobacco rod error can be judged, and the processing unit 10 in the cartridge encryption anti-counterfeiting chip stops working and does not transmit any signal back.

It can be understood that the processing unit 10 of the cartridge encryption anti-counterfeiting chip can also output a client code error signal when the client code calculation is incorrect. Besides the cigarette bullet encryption anti-counterfeiting chip, the electronic cigarette manufacturer can also be provided with a switch circuit and a control circuit, wherein the switch circuit is arranged between the heating wire and the output thimble of the cigarette bullet, and the control circuit is respectively and electrically connected with the cigarette bullet encryption anti-counterfeiting chip and the controlled end of the switch circuit. When the control circuit receives a customer code error signal output by the cartridge encryption anti-counterfeiting chip, the switch circuit is controlled to be in an off state, so that a user cannot start the cartridge.

In this embodiment, if the processing unit 10 of the cartridge confirms that the first calculation value is consistent with the preset first calculation value, the factory code currently stored in the storage unit 30 is read and output to the encryption operation unit 20, the encryption operation unit 20 is controlled to encrypt the client code and the factory code according to the preset encryption coding rule to form an encryption code, the encryption operation unit 20 is controlled to convert the encryption code into the code according to the code hopping rule that the cigarette is bounced to the tobacco stem when the cartridge is plugged last time, the encryption operation unit 20 is controlled to randomly generate the code hopping rule, and the code hopping code and the code hopping rule generated randomly at this time are returned to the tobacco stem together, so that the tobacco stem restores the code hopping code to the encryption code according to the code hopping rule that the cigarette is bounced to the tobacco stem when the cartridge is plugged last time, and then the authenticity of the cartridge is judged according to the encryption code and the preset decoding operation rule. The preset decoding rule is also designed directly by the chip producer and is arranged in the programming tool for burning the cigarette rod, so that the authentication of the cigarette bullet is realized.

From the above, each time the cartridge is successfully plugged, the tobacco stem stores the randomly generated code hopping rule. Therefore, when the cigarette bullet encryption anti-counterfeiting chip is plugged in and plugged out next time, the formed new code hopping code can be generated according to the code hopping rule stored last time, a new code hopping rule is randomly generated at the same time, the new code hopping rule and the code hopping rule are transmitted to the cigarette stem together, so that the cigarette stem restores the code hopping code to the encrypted code according to the code hopping rule that the cigarette bounces when the cigarette bounces are plugged in and plugged in last time, authenticity of the cigarette bullet is judged according to the encrypted code and the preset decoding operation rule, and after the cigarette bullet is authenticated to be positive, the code hopping rule of this time is reserved, and therefore the code hopping code transmitted by the cigarette bullet next time can be restored to the encrypted code. The preset decoding operation rule is also set by a chip developer.

In addition, if the current cartridge is plugged in and pulled out for the first time, that is, the cartridge chip receives the client code of the current cartridge for the first time, the encryption code can be directly sent and the code hopping rule is randomly generated and transmitted to the cartridge at the same time, at the moment, the code hopping code is the encryption code, the cartridge can also find the corresponding code hopping rule which is not stored, for example, in the embodiment, the cartridge encryption anti-counterfeiting chip can also return the factory code of the cartridge at the same time, so that the cartridge determines the current model, determines whether the current cartridge is plugged in and pulled out for the first time, and stores the corresponding code hopping rule for the cartridge corresponding to different factory codes. Similarly, if a certain cartridge is plugged into the a tobacco rod for multiple times, and then plugged into the B tobacco rod for the first time, the stored code hopping rule is read according to the transmitted client code, if not, the encryption code can be directly sent, meanwhile, the code hopping rule is randomly generated and transmitted to the tobacco rod, so that the tobacco rod is authenticated, and the process is repeated in the subsequent plugging process according to the embodiment.

In summary, because of the code hopping rule, the code hopping codes transmitted each time are different, and pirates cannot read the code hopping codes therein as broken codes through devices such as oscilloscopes. Meanwhile, as the code hopping rule of each time is also random, pirates cannot find the rule generated by code hopping code of each time, so that the code hopping code cannot be cracked, and the anti-counterfeiting performance of the cigarette bullet is effectively improved.

In another embodiment of the present invention, the processing unit is further configured to output the code hopping code and the code hopping rule generated randomly at this time, and together with the code hopping code, the client code and the stored code hopping rule. Thus, the processing unit 10 can record the authentication times of the current tobacco rod and store the corresponding code hopping rules corresponding to different client codes. In addition, the client code, the corresponding code hopping code and the code hopping rule generated randomly at this time are stored, so that the code hopping rule generated randomly by the encryption operation unit 20 is controlled by the processing unit 10 each time is not repeated, the code hopping codes output each time are different, pirates cannot copy the code hopping codes effectively, and the anti-counterfeiting performance of the cigarette bullet encryption anti-counterfeiting chip is further improved.

According to the invention, communication between the cigarette rod and the cigarette bullet encryption anti-counterfeiting chip is realized by arranging the signal transmission end, and when the cigarette bullet is inserted into the cigarette rod, the client code output by the cigarette rod is accessed, so that the processing unit 10 outputs the client code to the encryption operation unit 20, and the encryption operation unit 20 obtains a first operation value after operation according to a preset operation rule and compares the first operation value with the preset first operation value. When the first calculation value is confirmed to be consistent with the preset first calculation value, the current tobacco rod is judged to be positive, the encryption operation unit 20 is controlled to encrypt the client code and the factory code according to a preset encryption coding rule to form an encryption code, the encryption operation unit 20 is controlled to generate the jump code according to the jump code rule transmitted to the tobacco rod by the tobacco spring back when the tobacco cartridge is plugged in last time, the encryption operation unit 20 is controlled to randomly generate the jump code rule, the jump code and the jump code rule randomly generated at this time are transmitted back to the tobacco rod together, so that the tobacco rod restores the jump code to the encryption code according to the jump code rule transmitted to the tobacco rod by the tobacco spring back when the tobacco cartridge is plugged in last time, authenticity of the tobacco cartridge is judged according to the encryption code and the preset decoding operation rule, and when the tobacco cartridge is true, the jump code and the jump code rule randomly generated at this time are stored. Therefore, the cigarette bullet encryption anti-counterfeiting chip can not only realize the authentication of the cigarette stems to the cigarette bullets, but also realize the authentication of the cigarette stems to the cigarette bullets, ensure that the cigarette bullets and the cigarette stems can start working after being mutually confirmed to be produced by the same legal provider, effectively improve the anti-counterfeiting performance of the electronic cigarette bullets and ensure the health and the safety of the user sucking the electronic cigarettes. In addition, the encryption anti-counterfeiting chip of the cigarette bullet also enables the data transmitted by each cigarette bullet and the cigarette stem for authentication to be different in each time of plugging and unplugging by the code jumping mode, thereby effectively preventing pirates from re-engraving the authentication data and further improving the anti-counterfeiting performance of the electronic cigarette bullet and the electronic cigarette.

Referring to fig. 1, in an embodiment of the present invention, the signal transmission terminal is further configured to simultaneously access the power signal to provide the operating voltage for the processing unit 10.

It should be understood that, in this embodiment, the electrical connection between the tobacco rod and the tobacco cartridge is often realized through the metal thimble, and in this embodiment, since the data of the mutual communication between the tobacco cartridge encryption anti-counterfeiting chip and the tobacco rod is a digital signal, and the voltage required by the processing unit 10 of the tobacco cartridge encryption anti-counterfeiting chip for operation is a direct current voltage, the signal transmission end can simultaneously realize the transmission of the data signal and the power signal through the carrier wave. Therefore, in practical application, the cartridge can simultaneously realize the functions of supplying power to the cartridge encryption anti-counterfeiting chip and communicating with the tobacco stem only by arranging a thimble for communication for the cartridge encryption anti-counterfeiting chip. Therefore, the number of extra ejector pins for communication is effectively reduced, the structure of the cartridge carrying the cartridge encryption anti-counterfeiting chip is simplified, and the production cost of the cartridge and the tobacco stem is reduced.

Through above-mentioned setting, can realize transmitting data signal and power signal simultaneously through a communication thimble on the cigarette bullet, reduce the cigarette bullet of electron cigarette and the thimble quantity on the tobacco rod effectively, retrench the structure of carrying the cigarette bullet of cigarette bullet encryption anti-fake chip, improve miniaturization and the integration of electron cigarette bullet and tobacco rod.

Referring to fig. 1, in an embodiment of the present invention, the processing unit is further configured to, while outputting the code hopping code and the code hopping rule randomly generated at this time, read the factory code in the storage unit 30 and output the factory code to the tobacco rod, so that the tobacco rod confirms the type of the cartridge, and store the received code hopping code corresponding to the factory code and the code hopping rule randomly generated at this time according to the factory code.

In this embodiment, as can be seen from the foregoing embodiment, the factory code of each cartridge encryption anti-counterfeit chip is different. Because the tobacco stems are often inserted into different tobacco cartridges, in the process of authenticating the tobacco cartridges, the code hopping rule of the tobacco cartridges, which is stored in the tobacco stems and corresponds to the factory code of the tobacco cartridges and is sent by the tobacco cartridges last time, is required to be searched for, and the code hopping code sent by the tobacco cartridges this time is restored and calculated. The misjudgment of the cartridges caused by the fact that the tobacco stems call wrong code jumping rules facing different cartridges is prevented.

Through the arrangement, the stability and the reliability of the operation of the cigarette bullet encryption anti-counterfeiting chip are effectively improved, and the accuracy and the reliability of the cigarette bullet with the encryption anti-counterfeiting chip are improved in the process of identifying and authenticating the cigarette stems.

It should be understood that if the pirate copies the encryption anti-counterfeiting chip of the cartridge of the present invention completely, misjudgment of the cartridge may be caused, so that the cartridge authentication of the pirated cartridge is correct, and the health of the user and legal benefits of the legal manufacturer are affected.

For this reason, referring to fig. 1, in an embodiment of the present invention, the processing unit is further configured to output, while outputting the code hopping code and the code hopping rule randomly generated at this time, a corresponding plug number signal to the tobacco stem according to the number of code hopping codes of the corresponding client codes already stored in the storage unit 30, so that the tobacco stem determines whether the tobacco cartridge is authentic according to the plug number signal and the number of stored code hopping codes of the corresponding factory codes.

It should be understood that in practical applications, pirates may mass produce imitated cartridges in view of earning illegal interests, but the factory codes of the batches of cartridges are consistent.

In this embodiment, as can be seen from the above, the processing unit outputs the code hopping code and the code hopping rule generated randomly at this time, and stores the code hopping code, the client code and the code hopping rule generated randomly at this time in the storage unit 30. Therefore, the processing unit may output the corresponding number of plugging times signal to the tobacco rod according to the number of the code hopping codes of the corresponding client code stored in the storage unit 30, for example, the α -cartridges have been inserted into the a-tobacco rod 2 times, and each time the α -cartridges are successfully authenticated, when the α -cartridges are inserted for the third time, the number of the code hopping codes of the corresponding a-cartridges currently stored should be 3, and similarly, the corresponding a-tobacco rod will have a record that the α -cartridges have been inserted 3 times. At this time, if the user takes the counterfeit α cartridge, the number of times of inserting and extracting the corresponding a-cartridge in the a-cartridge is 1, but the number of times of inserting and extracting the corresponding α -cartridge in the a-cartridge should be 4 times at this time, and the numbers of both sides are not identical, at this time, the a-cartridge judges that the current α -cartridge is counterfeit, so the operation of the cartridge is stopped.

In addition, the preset programming tool for burning the tobacco stems can lock the delivery codes determined as pirate tobacco cartridges, so that when the subsequent tobacco cartridges are inserted, if the delivered delivery codes are consistent with the locked delivery codes, the tobacco stems directly stop working. From the above, it can be seen that the cartridges produced by the pirate are all the same factory code, and when one of them is judged as the pirate cartridge and locked with the factory code, the other pirate cartridges cannot work during insertion because the factory code is consistent with the cartridge.

Through the arrangement, the complete hardware re-engraving of the anti-counterfeiting encryption chip for the cartridge encryption can be effectively prevented by pirates, the anti-counterfeiting performance of the cartridge is further improved, and the health of users for sucking and legal benefits of manufacturers are ensured.

Referring to fig. 2, in an embodiment of the present invention, the cartridge encryption anti-counterfeit chip further includes a recording end, and the recording end is electrically connected with the processing unit 10;

the burning terminal is used for accessing an external terminal and receiving a working mode signal burnt in by the external terminal;

a processing unit 10, configured to store the operation mode signal burnt in by the external terminal in a storage unit 30;

the processing unit 10 is further configured to read the operation mode signal in the storage unit 30 and output the operation mode signal to the tobacco rod together while outputting the code hopping code and the code hopping rule randomly generated at this time, so that the tobacco rod works according to the operation mode corresponding to the operation mode signal after confirming that the cartridge is true.

In this embodiment, the bullet producer can autonomously customize part of the functions of the bullet encryption anti-counterfeiting chip, burn the designed working mode signal into the bullet encryption anti-counterfeiting chip, store the signal in the storage unit 30 by the processing unit 10, and read the working mode signal in the storage unit 30 and output the signal to the tobacco stem together when the jump code and the jump code rule randomly generated at this time are output, so that the tobacco stem works according to the working mode corresponding to the working mode signal after confirming that the bullet is true.

In this embodiment, the working units corresponding to the working mode signals may be working modes with different cartridge tastes, and it is to be understood that the basic working principle of the tobacco tar type electronic cigarette is that the tobacco stems output voltages with different magnitudes to heating wires in the cartridges, so that the heating wires atomize surrounding tobacco tar after heating, and the surrounding tobacco tar is inhaled by a user through an air flue, and because different types of tobacco tar have different components, the tastes experienced by the user are different at different temperatures (temperatures of the heating wires), namely, when the tobacco stems output different voltages. So in order to guarantee that the user can have better taste experience when using the cigarette bullet of different tastes, the cigarette bullet producer can design and burn different work unit signals according to the difference of current cigarette bullet tobacco tar taste, for example the cigarette bullet of peppermint tobacco tar, its design adopts 3.5V voltage for the heating, when peppermint flavor cigarette bullet inserts the tobacco rod like this, the tobacco rod is carrying out the authentication, confirms that current cigarette bullet is the true back, just works with the mode that the working mode signal corresponds, when the user carries out the smoking action, outputs 3.5V voltage to the heater of cigarette bullet. Therefore, the individual customized service can be carried out on the cartridges with different tastes, so that the user can have better taste when sucking the cartridges with different tastes.

In this embodiment, the unit of work signal can also act as a restriction to allow the use of cartridges to comply with laws and regulations in the country and region in which the user is located. For example, when a user inserts a cartridge in an area where smoking is prohibited, after the user completes authentication of the cartridge and determines that the cartridge is authentic, the user can determine whether the current positioning position is the area where smoking is prohibited according to the data content of the working mode signal and through an external terminal in communication connection with the external terminal, if smoking is prohibited in the current occasion in public places, the operation of the cartridge can be stopped, and the user cannot inhale the cartridge.

In addition, among the e-cigarette tobacco tar, there is a CBD (cannabidiol) tobacco tar, in which CBD is extracted from cannabis. However, at present, CBD tobacco tar is illegal in some countries and regions, if a user brings CBD tobacco cartridges from a region where CBD tobacco tar is legal into a region where CBD tobacco tar is prohibited, and inserts CBD tobacco cartridges into a tobacco stem, the tobacco stem, after authenticating that the current tobacco cartridge is genuine, determines that the current region prohibits sucking CBD tobacco cartridges according to the data content of a working unit signal and a location address of an external terminal, such as a mobile phone, connected with the tobacco stem in a communication manner, thereby stopping the work of the tobacco stem and making the user incapable of sucking the tobacco cartridges.

In addition, in another embodiment, in order to prevent the memory in the cigarette rod from being insufficient, a part of the working program content can be burnt in the cigarette bullet encryption anti-counterfeiting chip, and after the cigarette rod is authenticated, the working mode signal in the cigarette bullet encryption anti-counterfeiting chip is read for working. Therefore, the program storage space of the electronic cigarette can be improved under the condition that the appearance of the cigarette rod body is not changed.

Through the arrangement, the cigarette bullet producer can set different working modes according to different cigarette bullets according to the design requirements of the cigarette rods or the electronic cigarettes, so that the experience of a user is improved, and the program storage space of the cigarette rods is saved. The use of the cigarette bullet can be in accordance with laws and regulations of the country and region where the user is located, so that the health and standardization of the use of the electronic cigarette are ensured.

Referring to fig. 2, the cartridge encryption anti-counterfeit chip further includes a clock unit 40;

the clock unit 40 is electrically connected with the processing unit 10 and the encryption operation unit 20, respectively;

the processing unit 10 is further configured to control the clock unit 40 to generate a timing signal corresponding to the timing control signal according to the timing control signal, so as to provide working timing for the processing unit 10 and the encryption operation unit 20.

In this embodiment, the clock unit 40 may be implemented by a crystal oscillator, a voltage-controlled LC oscillator, etc., and the processing unit 10 may output a clock generation signal according to a timing control signal burnt in by an external terminal, control the clock unit 40 to generate a corresponding timing signal, and provide working timings for the processing unit 10 and the encryption operation unit 20. Therefore, a user can select corresponding time sequences according to requirements, so that the time sequences of data and signals output by the cartridge encryption anti-counterfeiting chip are matched with the time sequences of the tobacco stems, and the period duration of the working time sequences can be reduced according to requirements, so that the time for transmitting the data between the cartridge encryption anti-counterfeiting chip and the tobacco stems is effectively reduced, and the efficiency of mutual communication is improved.

Specifically, taking the voltage-controlled crystal oscillator as an example of the clock unit 40, the processing unit 10 may output a PWM signal with a corresponding duty ratio according to a preset clock-PWM duty ratio (determined by parameters of the voltage-controlled crystal oscillator) and a timing control signal, so that the voltage-controlled crystal oscillator generates a corresponding timing signal.

Through the arrangement, the design requirement of a user on the working time sequence of the cigarette bullet encryption anti-counterfeiting chip can be met, each period of the working time sequence can be properly reduced according to actual conditions, so that the time for transmitting data between the cigarette bullet encryption anti-counterfeiting chip and a cigarette stem is shortened, and the efficiency of mutual communication is improved.

It is noted that, since the cartridge of the present invention includes the above-mentioned cartridge encryption anti-counterfeiting chip, the embodiments of the present invention include all the technical solutions of all the embodiments of the above-mentioned cartridge encryption anti-counterfeiting chip, and the achieved technical effects are identical, and are not described herein again.

Referring to fig. 3, the invention further provides an electronic cigarette, which comprises a cigarette stem, a cigarette cartridge and the cigarette cartridge encryption anti-counterfeiting chip according to any one of the above, wherein the cigarette cartridge encryption anti-counterfeiting chip is arranged in the cigarette cartridge, the cigarette cartridge and the cigarette stem are connected in a pluggable manner, and the cigarette cartridge comprises a connecting end which is connected with a signal transmission end.

The cigarette rod comprises a communication end, a control unit 70, a decoding operation unit 100, a power supply unit 80, a memory 60 and an insertion detection unit 90, wherein the communication end is respectively and electrically connected with the power supply unit 80 and the control unit 70, the communication end is used for connecting with the connecting end of the cigarette cartridge, and the power supply unit 80 is respectively and electrically connected with the control unit 70 and the decoding operation unit 100; the control unit 70 is electrically connected with the decoding operation unit 100, the memory 60 and the insertion detection unit 90, respectively, and the client code is pre-stored in the memory 60;

The insertion detection unit 90 is configured to detect a cartridge insertion state and output a corresponding insertion detection signal;

the control unit 70 is configured to read the client code in the memory 60 and output the client code to the cartridge through the communication terminal when determining that the cartridge is inserted according to the insertion detection signal;

the control unit 70 is further configured to confirm the type of the cartridge according to the factory code, and read the code jumping rule that the corresponding cigarette in the memory 60 is bounced and transferred to the cigarette stem when the cigarette is plugged and unplugged last time according to the type of the cartridge;

the control unit 70 is further configured to, when receiving the code hopping code, read a code hopping rule that the cigarette bounces and transmits to the cigarette stem when the cigarette is plugged in and plugged out last time, and control the decoding operation unit 100 to restore the code hopping code to an encrypted code according to the code hopping rule that the cigarette bounces and transmits to the cigarette stem when the cigarette is plugged in and plugged out last time, perform decoding operation on the encrypted code according to a preset decoding operation rule, obtain a second operation value, compare the second operation value with the preset second operation value, and when the second operation value is consistent with the preset second operation value, the control unit 70 confirms that the current cigarette bounces are correct and keep working state, and store the code hopping rule and the code hopping code that are randomly generated this time; when the second calculation value is inconsistent with the preset second calculation value, the control unit 70 stops working;

The control unit 70 is further configured to compare the number of plugging times recorded by the cartridge with the number of corresponding skip codes stored in the memory 60 according to the number of plugging times signal sent by the cartridge, and if the number of plugging times recorded by the cartridge is inconsistent with the number of corresponding skip codes stored in the memory 60, the control unit 70 stops working;

the control unit 70 is further configured to perform operation according to an operation mode corresponding to the operation mode signal sent from the cartridge after confirming that the cartridge is genuine.

In this embodiment, the communication end may be a metal thimble, and when the cartridge is inserted, the connection end of the cartridge contacts with the communication end, so as to realize the electrical connection between the signal transmission end of the cartridge encryption anti-counterfeiting chip and the communication end of the tobacco rod, so that the power supply unit 80 of the tobacco rod provides working voltage for the cartridge encryption anti-counterfeiting chip of the cartridge through the communication end, and meanwhile, the carrier technology is used to transmit the working voltage and simultaneously, the digital signal data can be mutually transmitted.

In this embodiment, after receiving the code hopping rule and code hopping code transmitted from the cartridge and the factory code, the control unit 70 firstly confirms the cartridge type according to the factory code, reads the code hopping rule transmitted from the last time when the cartridge is plugged in and pulled out corresponding to the cartridge type, restores the code hopping code received this time to an encrypted code, then controls the decoding operation unit 100 to perform decoding operation on the encrypted code according to a preset decoding operation rule (set by a chip developer), and then compares the decoded code with a preset second operation value (set by the chip developer), if the decoded code hopping rule and the code hopping code are consistent, the control unit 70 judges that the current cartridge is true, and stores the code hopping rule and the code hopping code randomly generated this time in the memory 60 and stores the code hopping rule and the code hopping code in the memory space corresponding to the factory code.

It will be appreciated that there is a very small probability that pirates will completely re-etch the cartridges and their internal devices to produce large quantities of pirated cartridges of the same factory code. For this reason, in this embodiment, the control unit 70 also receives the number of plugging signals at the same time, since the factory code of the cartridge encryption anti-counterfeiting chip in each cartridge is different and the customer code in each control unit 70 and the customer code of each cartridge are also different, and it is known that after verifying that the code of the present skip code is correct, the present skip code is stored in the memory 60, so if the cartridge is true, after the code skip code decoding is correct, the number of skip codes in the memory 60 and the number of plugging signals transmitted from the cartridge should be consistent, for example, the current original α cartridge and the original a cartridge, the α cartridge has been successfully plugged into the a cartridge twice before this time, at this time, the user takes out the α cartridge and inserts the a cartridge again, and after verifying the customer code of the a cartridge, the α cartridge generates and stores a new skip code and a randomly generated skip code according to the rules generated during the second time of inserting. At this time, the α -ray should have four code hopping codes (the first code hopping code is the encryption code itself) and three code hopping rules recorded therein, and output corresponding plug frequency signals to the tobacco stem at the same time, so as to indicate that the current α -ray has been inserted four times. After decoding and checking the new jump code, the jump code is stored in the memory 60, the number of the jump code stored at the moment is 4, and the number of the jump code is consistent with the number of the plugging signals, and the control unit 70 can judge that the current cartridge is true. If the numbers of times of the two sides of the inserted α -ray cartridge are inconsistent, the current α -ray cartridge is a pirated product, the control unit 70 will stop working and lock the delivery code corresponding to the α -ray cartridge. In this way, in the subsequent cartridge insertion process, if the factory code of the inserted cartridge is the locked factory code, the control unit 70 will stop directly, so that the large-batch pirate cartridges of the same factory code produced by the pirate manufacturer cannot be used, so as to prevent the user from sucking the current pirate cartridge, improve the use safety of the user, and improve the anti-counterfeiting performance of the electronic cigarette rod and the cartridge.

It should be understood that in practical applications, a heating unit and a triggering assembly are often disposed in the electronic cigarette, and a user controls the heating unit to operate by triggering the triggering assembly to suck the tobacco tar atomized in the cartridge. In this embodiment, when the control unit 70 confirms that the current cartridge is true, the user may trigger the trigger assembly to perform the sucking action, and when the control unit 70 confirms that the current cartridge is false, the control unit 70 enters a sleep state and stops receiving the signal transmitted from the trigger assembly, so that the user cannot suck the atomized tobacco tar.

Referring to fig. 3, in an embodiment of the present invention, the tobacco rod further comprises:

and a communication unit 50, wherein the communication unit 50 is electrically connected with the control unit 70, and the communication unit 50 is used for communication connection with an external terminal.

The control unit 70 is further configured to upload the stored plurality of factory codes and the corresponding plurality of code hopping codes and code hopping rules to the external terminal via the communication unit 50.

The control unit 70 is further configured to report the factory code corresponding to the locked cartridge to the external terminal via the communication unit 50 when the factory code corresponding to the cartridge is locked.

The communication unit 50 is further configured to receive a cartridge locking signal transmitted from an external terminal;

The control unit 70 is further configured to determine a factory locking code according to the cartridge locking signal, and stop the control unit 70 when the factory locking code of the cartridge is the factory locking code.

In this embodiment, the external terminal may be an electronic device such as a mobile phone or a tablet, and the control unit 70 of the tobacco rod may upload the stored plurality of factory codes, the corresponding plurality of jump code codes and the jump code rules to the external terminal through the communication unit 50, so that the user may see the current number of times of inserting and extracting the tobacco cartridge on the external terminal, for example, the corresponding APP of the mobile phone end, thereby improving the convenience of use of the user.

In addition, the external terminal can report the received data to the cloud server of the electronic cigarette manufacturer, so that the electronic cigarette manufacturer can know the preference of the user for different types and different tastes of cartridges through the big data.

In another embodiment, as can be seen from the above, when a counterfeit cartridge is generated, the tobacco rod locks the factory code of the pirated cartridge, so that the tobacco rod stops working uniformly when the factory code is inserted into the cartridge with the locked factory code. Meanwhile, the code is reported to the external terminal through the communication unit 50, so that the locked factory code is uploaded to the cloud end by the external terminal, and a background electronic cigarette manufacturer and a background chip manufacturer can know the code.

Meanwhile, the external terminal also transmits corresponding cartridge locking signals to all the tobacco stems according to the received locked delivery codes, so that when other produced tobacco stems are in communication connection with the external terminal, the cartridge locking signals received by the communication unit 50 determine the locked delivery codes, and in the subsequent process of inserting the cartridges, if the delivery code of a certain cartridge is consistent with the locked delivery code, the control unit 70 directly stops working. Meanwhile, the tobacco rod can also comprise an indication component, and the control unit 70 can control the indication component, for example, a display screen displays the current cigarette bullet errors, so that the cigarettes with the same factory code, which are produced by pirates in a large scale in a repeated way, cannot be used on the tobacco rod of the original version, and the anti-counterfeiting performance of the electronic cigarette is further improved.

It is worth noting that, because the electronic cigarette of the present invention is based on the above-mentioned cartridge encryption anti-counterfeiting chip, the embodiments of the electronic cigarette of the present invention include all the technical schemes of all the embodiments of the above-mentioned cartridge encryption anti-counterfeiting chip, and the achieved technical effects are identical, and are not described in detail herein.

Referring to fig. 4, the invention further provides a cartridge authentication method, which is implemented based on the electronic cigarette, and comprises the following steps:

Step S100, when a cigarette cartridge is inserted into a cigarette rod, the cigarette cartridge acquires a client code sent by the cigarette rod, calculates the client code according to a preset calculation rule, and then obtains a first calculation value, and compares the first calculation value with the preset first calculation value;

step 200, when the first calculation value is consistent with the preset first calculation value, the cigarette bullet confirms that the current cigarette stem is correct, and the client code and the factory code preset and stored in the cigarette bullet are encrypted according to a preset encryption coding rule to form an encryption code;

step S300, the cigarette bullet generates the code hopping code according to the code hopping rule that the cigarette bounces and transmits to the cigarette stem when the cigarette is plugged and unplugged last time, randomly generates and stores the code hopping rule to the cigarette bullet, and transmits the code hopping code and the code hopping rule randomly generated this time back to the cigarette stem;

step S400, the tobacco rod restores the code hopping code to the encryption code according to the code hopping rule that the tobacco bounces are transmitted to the tobacco rod when the tobacco rod is plugged and unplugged last time, the encryption code is decoded and operated according to the preset decoding algorithm, a second algorithm value is obtained and compared with the preset second algorithm value, when the second algorithm value is consistent with the preset second algorithm value, the tobacco rod confirms that the current tobacco cartridge is correct and starts working, and the randomly generated code hopping rule and code hopping code are stored in the tobacco rod; and when the second calculation value is inconsistent with the preset second calculation value, stopping working of the tobacco stem.

It is to be understood that the method is based on the electronic cigarette stem and the cigarette cartridge with the electronic cigarette encryption anti-counterfeiting chip.

In this embodiment, when the cartridge is inserted into the cartridge, the cartridge detects that the cartridge is inserted into the cartridge and outputs the client code, at this time, the cartridge performs operation according to a preset operation rule (the preset operation rule is set by the chip manufacturer), and then obtains a first operation value, and compares the first operation value with the preset first operation value, for example, according to the preset operation rule, the client code is added from the first bit to the last bit to be 100, if the client code cannot be received or the sum of the client codes is not 100, it can be determined that the current cartridge is wrong, the processing unit 10 in the cartridge encryption anti-counterfeiting chip stops working, and does not transmit any signal back.

Referring to fig. 5, in an embodiment of the present invention, before step S400, the method further includes:

s500, reading a preset stored factory code and outputting the factory code to a tobacco rod when the code hopping code and the code hopping rule randomly generated at the time are output by the tobacco cartridge;

and S600, determining the type of the cigarette bullet according to the received delivery code by the cigarette stem, and reading the code jumping rule that the cigarettes rebound to the cigarette stem when being plugged and pulled last time, which is stored in the cigarette stem, according to the type of the cigarette bullet.

From the foregoing, it can be seen that if a pirate perfectly rewrites the cartridge and its internal components, the tobacco rod may also be misjudged for the current pirate cartridge.

For this purpose, referring to fig. 6, in an embodiment of the present invention, after step S400, further includes:

step S700, the cartridge stores the code hopping code and the corresponding client code in the cartridge while outputting the code hopping code and the code hopping rule randomly generated at this time;

step S800, the tobacco cartridges generate plugging frequency data according to the number of code hopping codes stored in the tobacco cartridges and transmit the plugging frequency data to tobacco stems;

step S900, comparing the number of the code hopping codes stored in the tobacco stems with the number of the code hopping codes stored in the tobacco stems according to the number of the plugging times, stopping the tobacco stems from working and locking the current factory codes if the number of the plugging times is inconsistent with the number of the code hopping codes stored in the tobacco stems; if the number of the plugging times data is consistent with the number of the jump code codes stored in the memory, the tobacco stem keeps working state.

In this embodiment, it is known from the above that after the client code of the tobacco rod is authenticated, the tobacco cartridge outputs the code hopping code and the code hopping rule randomly generated at this time, and stores the code hopping code and the corresponding client code in the tobacco cartridge, for example, the number of code hopping codes stored in the tobacco cartridge is 2 after two normal authentications are performed on the current α -tobacco cartridge with a master, and if the third insertion is performed, the number of code hopping codes stored in the α -tobacco cartridge with a master is 3, and similarly, the number of times of corresponding α -tobacco cartridge records in the tobacco rod is 3. At this time, if a brand new alpha cartridge which is not plugged and unplugged is taken for testing, the number of times of inserting the cigarette rod correspondingly in the alpha cartridge which is plugged and unplugged is 1 time, but in practice, the cigarette rod is already plugged 3 times, the number of two sides cannot be consistent, and the delivery code of each cartridge is unique, so that the cigarette rod can confirm that the current cartridge is the cartridge which is plugged and stops working.

In addition, in another embodiment of the present invention, after confirming that the current cartridge is a fake one, the tobacco rods can directly lock the corresponding delivery code of the current cartridge, or through an internal communication circuit, the APP uploaded to the external terminal is used for alarming, so that when all the tobacco rods which are produced at present are in communication connection with the external terminal, the locking signal sent by the external terminal is received, so as to lock the alarming delivery code, and when any tobacco rod is inserted into the cartridge, if the delivery code of the cartridge is the alarming delivery code, the operation is directly stopped and the alarm prompts the current cartridge to be wrong.

Due to the fact that the factory codes of the tobacco cartridges copied by the pirates are consistent, and large-scale production is often carried out for illegal benefits, through the arrangement, the current factory codes can be immediately locked as long as the tobacco stems confirm that the current tobacco cartridges are the re-engraving pirates, and all the pirate tobacco cartridges produced by the pirates cannot be used.

Through the arrangement, the full hardware re-etching of the internal devices of the cartridge by pirates can be effectively prevented, the anti-counterfeiting performance of the cartridge is further improved, and the health of the user sucking and the legal benefits of manufacturers are ensured.

Referring to fig. 7, in an embodiment of the present invention, after step S900, the method further includes:

s1000, reading a preset working mode signal preset and stored in the cartridge and outputting the preset working mode signal to a tobacco stem when the cartridge outputs a code hopping code and a code hopping rule randomly generated at the time;

and S1100, after the tobacco stem confirms that the tobacco cartridge is correct, working according to a preset working mode corresponding to the preset working mode signal.

In this embodiment, the cartridge further stores a preset operation mode signal, where the preset operation mode signal is set by the electronic cigarette producer and is burned in the cartridge together, so that the tobacco rod works according to the preset operation mode corresponding to the preset operation mode signal after the tobacco rod is confirmed to be correct. For example, different heating currents or preset heating temperatures through the atomizing wires are set for different cartridges with different tastes, so that the tobacco stems can control the heating temperatures of tobacco tar in the cartridges to be kept within a certain preset heating temperature interval when a user sucks the cartridges according to preset working mode signals transmitted by the cartridges, the sucking taste of the cartridges with different tastes is guaranteed, and the experience of the user is improved.

In addition, a part of heating programs of the electronic cigarette can be directly preset and stored in the cigarette bullet as a preset working mode signal, after the cigarette bullet is inserted and the cigarette stem verifies that the cigarette bullet is correct, the cigarette stem can work according to the transmitted heating programs, so that the number of the programs stored in the cigarette stem can be effectively reduced, and the program storage space of the cigarette stem of the electronic cigarette is improved under the condition that the volume of the cigarette stem is not changed.

It is worth noting that, because the cartridge authentication method of the present invention is based on the electronic cigarette and the cartridge encryption anti-counterfeiting chip, embodiments of the cartridge authentication method of the present invention include all technical schemes of all embodiments of the electronic cigarette and the cartridge encryption anti-counterfeiting chip, and the achieved technical effects are identical, and are not repeated herein.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
