[0022] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0023] Figure 1 A schematic diagram of the structure of an electronic cigarette provided by an exemplary embodiment of the present application, the electronic cigarette comprises: a cigarette rod 11, a cigarette cartridge 12; wherein the cigarette rod 11 is provided with a processing unit 111 and a decryption chip 112; and the cigarette cartridge 12 is provided with an encryption chip 121;

[0024] The processing unit 111 may be a microprocessor unit MCU, which is used to send a startup instruction to the decryption chip 112 when it is detected that the cigarette rod 11 is not in use. After sending the startup instruction, the processing unit 111 switches to a dormant state;

[0025] The decryption chip 112 is used to receive the startup instruction and enter the cartridge detection mode based on the startup instruction; in the cartridge detection mode, a first detection signal is sent; when a first response signal corresponding to the first detection signal is received within a first set time, it is determined that a cartridge 12 is connected to the cigarette rod 11.

[0026] The encryption chip 121 is used to feed back the first response signal to the decryption chip 112 when receiving the first detection signal.

[0027] The decryption chip 112 is a chip used to authenticate the cigarette cartridge 12 by interacting with the encryption chip 121 in the cigarette cartridge 12 .

[0028] The first detection signal may be a pulse signal, and the first response signal is sent by the encryption chip 121 in the cigarette cartridge 12 . When the cigarette cartridge 12 is connected to the cigarette rod 11 , the encryption chip 121 may receive the first detection signal and send a first response signal to the decryption chip 112 .

[0029] The first set time can be determined by the historical time consumed from the decryption chip 112 sending out the first detection signal to receiving the first response signal when the cigarette cartridge 12 is connected to the cigarette rod 11.

[0030] The startup instruction may also include the frequency of the detection signal, and the decryption chip 112 may send the first detection signal according to the frequency, and the first set time may also be the duration of the sending cycle corresponding to the sending frequency. For example, if the sending cycle is 2s or 5s, the first set time is also 2s or 5s.

[0031] When the decryption chip 112 detects that the cigarette cartridge 12 is disconnected from the cigarette rod 11, it sends a first wake-up signal to the processing unit 111 to wake up the processing unit 111, that is, the processing unit 111 is also used for:

[0032] Obtaining a first wake-up signal;

[0033] Switching from a sleep state to a working state based on the first wake-up signal;

[0034] The first prompt unit on the cigarette rod 11 is controlled to work, and a user-perceivable prompt about the disconnection of the cigarette rod 11 and the cigarette cartridge 12 is output.

[0035] When the decryption chip 112 detects that the cigarette cartridge 12 is reconnected to the cigarette rod 11, a second wake-up signal is sent to the processing unit 111 to wake up the processing unit 111, that is, the processing unit 111 is also used for:

[0036] Obtaining a second wake-up signal;

[0037] Switching from a sleep state to a working state based on the second wake-up signal;

[0038] The second prompt unit on the cigarette rod 11 is controlled to work, and a user-perceivable prompt about the connection between the cigarette rod 11 and the cigarette cartridge 12 is output.

[0039] The processing unit 111 and the decryption chip 112 communicate with each other based on the I2C bus, and the decryption chip 112 and the encryption chip 121 communicate with each other through double contacts.

[0040] The solution provided by the embodiment of the present application is that after receiving the start-up instruction sent by the processing unit, the decryption chip automatically detects whether the cigarette cartridge is connected to the cigarette rod; that is, after the decryption chip obtains the start-up instruction, it enters the cigarette cartridge detection mode based on the start-up instruction; in the cigarette cartridge detection mode, a first detection signal is sent; when a first response signal corresponding to the first detection signal is received within a first set time, it is determined that a cigarette cartridge is connected to the cigarette rod. The solution of the present application gives the decryption chip the function of actively searching for cigarette cartridges, thereby realizing that in the process of searching for cigarette cartridges, the MCU does not need to be fully involved, reducing the power consumption of the MCU.

[0041] The execution principles and interaction processes of the component units in this embodiment, such as the processing unit, the decryption chip and the encryption chip, can be found in the description of the following method embodiments.

[0042] Figure 2 A flowchart of a method for finding a cigarette cartridge provided by an exemplary embodiment of the present application is applicable to a decryption chip in a cigarette rod. The method includes:

[0043] 201. Receive a start instruction sent by a processing unit;

[0044] 202. Entering a cigarette cartridge detection mode based on the startup instruction;

[0045] 203. In the cigarette cartridge detection mode, a first detection signal is sent;

[0046] 204. When a first response signal corresponding to the first detection signal is received within a first set time, it is determined that a cigarette cartridge is connected to the cigarette rod.

[0047] The decryption chip is a chip used to authenticate the cigarette cartridge by interacting with the encryption chip in the cigarette cartridge. After the processing unit sends the startup instruction, it will switch to a dormant state. The processing unit is a microprocessor unit MCU.

[0048] The first detection signal may be a pulse signal, and the first response signal is sent by the encryption chip in the cigarette cartridge. When the cigarette cartridge is connected to the cigarette rod, the encryption chip may receive the first detection signal and send a first response signal to the decryption chip.

[0049] The first set time can be determined by the historical time consumed from the decryption chip sending out the first detection signal to receiving the first response signal when the cigarette cartridge is connected to the cigarette rod.

[0050] The startup instruction may also include a detection signal sending frequency, and the decryption chip may send the first detection signal according to the sending frequency, and the first set time may also be the duration of the sending cycle corresponding to the sending frequency. The sending frequency of the detection signal may also be pre-stored in the decryption chip.

[0051] In addition to determining whether a cigarette cartridge is connected to the cigarette rod, the decryption chip can also detect whether the cigarette cartridge is disconnected from the cigarette rod. Specifically, after the decryption chip determines that the cigarette cartridge is connected to the cigarette rod, it can further send a second detection signal according to the frequency of the detection signal; determine whether the cigarette cartridge is disconnected from the cigarette rod based on whether a second response signal corresponding to the second detection signal is received, and wake up the processing unit when it is detected that the cigarette cartridge is disconnected from the cigarette rod. That is, the cigarette cartridge search method provided by the present application also includes the following steps:

[0052] 205. When a second response signal corresponding to the second detection signal is not received within a second set time, it is determined that the cigarette cartridge is disconnected from the cigarette rod;

[0053] 206. Send a first wake-up signal to the processing unit to wake up the processing unit, and the processing unit controls the first prompt unit on the cigarette rod to operate and output a user-perceivable prompt that the cigarette rod is disconnected from the cigarette cartridge.

[0054] The first prompt unit mentioned above can be an indicator light control unit in the cigarette rod, and can also be a vibration control unit in the cigarette rod. Specifically, when the processing unit is awakened by the first awakening signal, the indicator light can be controlled to light up and / or the cigarette rod can vibrate.

[0055] The first wake-up signal may specifically be a high-level signal, and the second set time may be the same as the first set time, or may be longer than the first set time, and may be longer than the sending cycle of the detection signal.

[0056] Through the above scheme, when the decryption chip detects that the cigarette cartridge is disconnected from the cigarette rod, that is, the cigarette cartridge is pulled out, it wakes up the processing unit to control the first prompt unit to work and output a user-perceivable prompt, so that the user can know the current status of the cigarette cartridge and improve the user experience.

[0057] After the cigarette cartridge is disconnected from the cigarette rod, the decryption chip can also detect whether the cigarette cartridge and the cigarette rod are reconnected, that is, the cigarette cartridge search method also includes:

[0058] 207. Send out a third detection signal according to the sending frequency of the detection signal;

[0059] 208. When a third response signal corresponding to the third detection signal is received within a third set time, it is determined that the cigarette cartridge is connected to the cigarette rod;

[0060] The third set time may be the same as the second set time, and the third detection signal may be the same as the first detection signal and the second detection signal.

[0061] Correspondingly, the above-mentioned smoke bomb searching method also includes:

[0062] 209. Send a second wake-up signal to the processing unit to wake up the processing unit, and the processing unit controls the second prompt unit on the cigarette rod to operate and output a user-perceivable prompt about the connection between the cigarette rod and the cigarette cartridge.

[0063] Specifically, in order to enable the processing unit to distinguish the current state of the cigarette cartridge, the second wake-up signal is different from the first wake-up signal, the second wake-up signal can be a low level, and the second prompt unit can be the same as the first prompt unit. When the decryption chip detects that the cigarette cartridge is reconnected to the cigarette rod, it wakes up the processing unit to control the second prompt unit to work and output a user-perceivable prompt, so that the user can know the current state of the cigarette cartridge and improve the user experience.

[0064] To sum up, in the cigarette cartridge finding method provided by the present application, the process of finding the cigarette cartridge is independently completed by the decryption chip, and the processing unit only sends a startup instruction to the decryption chip. A low-power automatic cigarette finding function is newly added inside the decryption chip. Through the above scheme, the present application gives the decryption chip an additional cigarette cartridge finding function in addition to identifying and authenticating the cigarette cartridge, thereby achieving the technical effect of reducing the power consumption of the MCU during the cigarette cartridge finding process.

[0065] Figure 3 A schematic diagram of a smoke bomb search method provided in this application includes the following steps:

[0066] 301. MCU detects whether the user stops smoking or does not smoke; if so, executes the following steps 302;

[0067] 302. The MCU sends a startup instruction to the decryption chip, so that the decryption chip starts the automatic cigarette cartridge search function, and the MCU goes into sleep mode.

[0068] 303. The decryption chip receives the start-up instruction, enters the cigarette cartridge detection mode based on the start-up instruction, and obtains the cigarette cartridge search result;

[0069] 304. The decryption chip feeds back the smoke bomb search result to the MCU.

[0070] The specific way in which the MCU detects whether the user has stopped smoking or has not smoked is as follows: when the sensor associated with the cigarette holder detects that the cigarette rod is in an unused state, it means that the user has stopped smoking or has not smoked.

[0071] When the decryption chip enters the cigarette cartridge detection mode, the detection result is obtained based on the response of the encryption chip in the cigarette cartridge. In the cigarette cartridge detection mode, the decryption chip sends a first detection signal to the encryption chip; when a first response signal corresponding to the first detection signal sent by the encryption chip is received within a first set time, it is determined that a cigarette cartridge is connected to the cigarette rod.

[0072] The above-mentioned start instruction may also carry the sending frequency of the detection signal, and the decryption chip may send the first detection signal to the encryption chip according to the sending frequency.

[0073] In the above scheme, the process of finding the smoke bomb is executed by the decryption chip, thereby achieving the technical effect of reducing the power consumption of the MCU during the process of finding the smoke bomb.

[0074] Figure 4 This is a flow chart of a smoke bomb locating method provided in the present application. The smoke bomb locating method is applicable to a processing unit and may specifically include the following steps:

[0075] 401. When the cigarette rod is detected to be in an unused state, a start instruction is sent to the decryption chip; wherein the start instruction is used to control the decryption chip to enter a cigarette cartridge detection mode, and the decryption chip sends a detection signal in the cigarette cartridge detection mode to determine whether a cigarette cartridge is connected to the cigarette rod based on whether a corresponding response signal is received within a set time;

[0076] 402. Switch the current state to the sleep state.

[0077] Specifically, when the processing unit determines whether the cigarette rod is in an unused state, it can do so in the following way: determine whether data from the sensor corresponding to the cigarette holder is received within a preset time period; if so, it means that the user is smoking and the cigarette rod is in use; if not, it means that the user has stopped smoking and the cigarette rod is in an unused state.

[0078] In some optional embodiments, the above method further includes:

[0079] Obtaining a first wake-up signal;

[0080] Switching from a sleep state to a working state based on the first wake-up signal;

[0081] The first prompt unit on the cigarette rod is controlled to operate and output a user-perceivable prompt that the cigarette rod is disconnected from the cigarette cartridge.

[0082] Among them, the first wake-up signal is the signal sent by the decryption chip when it detects that the cigarette cartridge is disconnected from the cigarette rod.

[0083] After the processing unit completes the control of the first prompt unit, if it detects that the cigarette rod is still in an unused state, the processing unit switches from the working state back to the dormant state.

[0084] In some optional embodiments, the above method further includes:

[0085] Obtaining a second wake-up signal;

[0086] Switching from a sleep state to a working state based on the second wake-up signal;

[0087] The second prompt unit on the cigarette rod is controlled to operate and output a user-perceivable prompt regarding the connection between the cigarette rod and the cigarette cartridge.

[0088] Among them, the second wake-up signal is the signal sent when the decryption chip detects that the cigarette cartridge and the cigarette rod are restored to connection.

[0089] For a specific implementation of the smoke bomb search method applicable to the processing unit, see Figure 2 The corresponding embodiments will not be described in detail here.
