The control circuit 117 of the smoking appliance 11 is also provided with a signal terminal 1170 for connecting to the voltage identification element 123 . In this embodiment, the control circuit 117 can obtain the voltage signal value from the voltage identification element 123 through the signal terminal 1170 . The voltage signal value can be used to identify different types of cartridges 12 . In this embodiment, the voltage identification elements 123 of different types of cartridges 12 may be different, so that the control circuit 117 obtains different voltage signal values for different types of cartridges 12 . The control circuit 117 can judge the type of the cartridge 12 according to the voltage signal value. In this embodiment, the number of each type of cartridge 12 may be one or more.

In some embodiments, the voltage signal values of the cartridges 12 of the same type are the same. For example, for the type A cartridge 12, the voltage signal value is 2V. In other embodiments, the voltage signal values of different types of cartridges 12 are different, and the voltage signal values of different cartridges in the same type of cartridges 12 may also be different. For example, for the type A pod 12, the voltage signal value ranges from 2-5V, and the type A pod 12 includes 5 pods, and the voltage signal values correspond to 2V, 3V, 3.5V, 4V, and 5V respectively. For the type B cartridge 12, the voltage signal value is, for example, 6-10V.

In a specific application scenario, the electronic cigarette 1 includes a set of voltage identification elements 123. When the cartridge 12 is placed on the smoking device 11, the power supply terminal 1160 of the smoking device 11 is connected to the power receiving terminal 1210 of the cartridge 12. The pod 12 supplies power, and the control circuit 117 of the smoking device 11 acquires a voltage signal value of 2V from the voltage identification element 123, and judges that the type of the pod 12 is type A. Or when the electronic cigarette 1 includes multiple sets of voltage identification elements 123, the voltage signal values of the multiple sets of voltage identification elements 123 can also be obtained, such as "5V, 4V, 3V, 2V" in sequence, and the voltage signal value of the cartridge 12 can be judged. type. In this embodiment, for only one set of voltage identification elements 123, compared with the high and low level signals "0" and "1", the control circuit 117 can distinguish at least three types of cartridges 12 through the voltage signal value.

In this embodiment, the electronic cigarette 1 is used to identify different types of cartridges 12 by setting the voltage identification element 123, and the voltage identification method can identify more types of cartridges 12, improving the scalability and flexibility of the identification of cartridges 12 The control circuit 117 can judge the type of the cartridge 12 through the voltage signal value from the voltage identification element 123, can quickly identify the type of the cartridge 12, and can be used as an anti-counterfeiting mark, and can also facilitate identification of different types of cartridges. The pod 12 adopts a corresponding working method or tracks and manages it, so as to realize the personalized control of the pod 12. In addition, in order to identify more types of pods, only the output voltage of the voltage identification element 123 needs to be changed, which is convenient for operation and low in manufacturing cost.

In this embodiment, the pod 12 further includes an identification terminal 1230 for connecting the voltage identification element 123 and the signal terminal 1170 respectively. For example, the identification end 1230 is connected to the voltage identification element 123 through a line, and the identification end 1230 and the signal end 1170 are electrically connected through contact, so that the control circuit 117 is connected to the voltage identification element 123 to receive the signal from the voltage The voltage signal value of the identification element 123 .

In this embodiment, the setting position of the voltage identification element 123 can have many situations, such as the following examples:

In the first case, the voltage identification elements 123 may all be located in the cartridge 12 .

In the second case, a part of the voltage identification element 123 is located in the cartridge 12 , and the other part is located in the smoking appliance 11 .

In the third case, the electronic cigarette 1 includes multiple sets of voltage identification elements 123, some of which are all located in the cartridge 12, and in other groups of voltage identification elements 123, each set of voltage identification elements 123 is partially Located in the smoking device 11 , the other part is located in the cartridge 12 , the combination of the voltage signal values of the multiple groups of voltage identification elements 123 is used to identify the type of the cartridge 12 .

Of course, there may be other situations. For example, the electronic cigarette 1 includes multiple sets of voltage identification elements 123, and some sets of voltage identification elements 123 are all located in the cartridge 12, while other sets of voltage identification elements 123 are all located in the smoking device 11. The combination of the voltage signal values of the group voltage identification elements is used to identify the type of the cartridge 12 .

For the first case, the voltage identification elements 123 can all be located in the cartridge 12, and this embodiment can be specifically described as follows:

The voltage identification element 123 may include a plurality of resistors connected in series and connected between the voltage source VDD and the ground. The identification terminal 1230 can be connected between any two adjacent resistors among multiple resistors, and the connection point between any two adjacent resistors will generate a voltage division due to the voltage division effect of the resistors, and the identification terminal 1230 can be obtained partial pressure value. For example, each group of voltage identification elements 123 includes four resistors, which are A resistor, B resistor, C resistor, and D resistor in sequence from the voltage source VDD to the ground, so the tag end can be connected between the A resistor and the B resistor, or can be connected to Between the B resistor and the C resistor, it can also be connected between the C resistor and the D resistor. In the following, it is taken as an example that each set of voltage identification elements 123 includes two resistors.

As shown in FIG. 3 , the voltage identification element 123 may include a first resistor 1231 and a second resistor 1232 . The first resistor 1231 and the second resistor 1232 can all be located in the cartridge 12 . One end of the first resistor 1231 is connected to the voltage source VDD, the other end is respectively connected to the identification end 1230 and one end of the second resistor 1232, and the other end of the second resistor 1232 is grounded. In this embodiment, the voltage source VDD can be the power supply circuit 116 of the smoking appliance 11, that is, one end of the first resistor 1231 is connected to the power receiving end 1210, so that when the smoking appliance 11 and the cartridge 12 are connected, the first resistor 1231 passes through The power receiving terminal 1210 and the power supply terminal 1160 receive voltage or current. For example, in some implementations, one end of the first resistor 1231 is connected to the receiving end 1210 so as to be coupled to the power supply end 1160 of the power supply circuit 116, the first resistor 1231 and the second resistor 1232 can be connected in series, and the identification end 1230 is connected to the first Between the resistor 1231 and the second resistor 1232 , that is, the other end of the first resistor 1231 . In some implementations, the resistance values of the first resistor 1231 and the second resistor 1232 of the multiple groups of voltage identification elements 123 may be different, corresponding to outputting different voltage signal values.

One end of the second resistor 1232 is connected to the identification terminal 1230 to generate a divided voltage, and the control circuit 117 obtains the divided voltage value through the signal terminal 1170 and the identification terminal 1230 as a voltage signal value. The control circuit 117 can judge the types of different cartridges 12 through the voltage signal value.

For example, the electronic cigarette 1 includes a set of voltage identification elements 123 . After the smoking device 11 and the pod 12 are combined, the control circuit 117 obtains the divided voltage value at one end of the second resistor 1232 through the signal terminal 1170 and the identification terminal 1230 . For example, the voltage source VDD is 5V, for a certain group of voltage identification elements 123, the first resistance 1211 is 3Ω, the second resistance 1212 is 2Ω, and the divided voltage value of the second resistance 1232 is 2V, then the potential of the identification terminal 1230 If it is 2V, then the voltage signal value output by the group of voltage identification elements 123 is 2V, and the value of the divided voltage of the second resistor 1232 is 2V, and the type of the corresponding pod 12 is, for example, type A. If the divided voltage value obtained by the control circuit 117 is 3V, the type of the corresponding pod 12 is Class B.

For example, the electronic cigarette 1 includes multiple groups of voltage identification elements 123, such as two groups, and the control circuit 117 obtains the divided voltage value of one group of 1V, and the divided voltage value of the other group of voltage identification elements 123 is 2V, then 1V2V can be used as the voltage The signal value corresponds to the type of pod 12 being A2. In this embodiment, the corresponding relationship between the voltage signal value and the type of the cartridge 12 can be designed according to the actual situation.

As shown in FIG. 3 , the number of identification terminals 1230 , the number of signal terminals 1170 and the number of groups of voltage identification elements 123 may be the same, and each identification terminal 1230 is connected to a voltage identification element 123 .

For example, the electronic cigarette 1 includes a group of voltage identification elements 123 , correspondingly including an identification terminal 1230 and a signal terminal 1170 . The one identification terminal 1230 is connected to the voltage identification element 123 and used to be connected to the signal terminal 1170 .

For example, the electronic cigarette 1 includes multiple sets of voltage identification elements 123, correspondingly including the same number of identification terminals 1230 and signal terminals 1170, each identification terminal 1230 is connected to a corresponding different signal terminal 1170 and a different set of voltage identification elements 123, and one One to one correspondence.

In order to reduce the number of identification terminals 1210, referring to the embodiment shown in FIG. 4 , a first selection circuit 124 can also be provided to make each group of voltage identification elements 123 communicate with the signal terminal 1170 in sequence, so that the control circuit 117 can obtain Each group of voltage identification elements 123 divides the voltage value, so that the number of identification terminals 1230 and signal terminals 1170 can be reduced.

As shown in FIG. 4 , the control circuit 117 may further include a control terminal 1171 . The cartridge 12 may further include a first selection circuit 124 . The first selection circuit 124 has a first controlled terminal 1240 , a first output terminal 1241 and a plurality of first input terminals 1242 . The first controlled terminal 1240 is used to connect to the control circuit 117 through the control terminal 1171 , the first output terminal 1241 is used to connect to the identification terminal 1230 , and each first input terminal 1242 is connected to a group of voltage identification elements 123 . Specifically, the first input terminal 1242 may be connected between the first resistor 1231 and the second resistor 1232 to obtain a voltage division value of the second resistor 1232 .

After the smoking appliance 11 is combined with the cartridge 12, the power supply terminal 1160 is connected to the power receiving terminal 1210 of the heating circuit 121, the control terminal 1171 of the control circuit 117 is connected to the first controlled terminal 1240 of the first selection circuit 124, and the control circuit 117 The signal terminal 1170 is connected to the identification terminal 1230 . The control circuit 117 outputs a selection signal to the first selection circuit 124 through the control terminal 1171 and the first controlled terminal 1240. After the first selection circuit 124 receives the selection signal through the first controlled terminal 1240, it identifies each group of voltages in sequence. The element 123 is connected to the identification terminal 1230, so that the control circuit 117 obtains the respective divided voltage values from each group of voltage identification elements 123, and the combination of the respective divided voltage values constitutes a voltage signal value.

For example, the number of voltage identification elements 123 is four, and the control circuit 117 outputs a selection signal to the first selection circuit 124 through the control terminal 1171 and the first controlled terminal 1240 . The first selection circuit 124 connects each group of voltage identification elements 123 sequentially, for example, connects each group of voltage identification elements 123 and the corresponding first input terminal 1242 sequentially. The control circuit 117 sequentially obtains the divided voltage values of the connected voltage identification elements 123 through the signal terminal 1170 and the identification terminal 1230, for example, 1V, 1V, 2V, and 2V in sequence, and the control circuit 117 combines the divided voltage values of each group to form a voltage signal The value, such as "1122", is used to identify a corresponding type of cartridge 12 or a cartridge 12.

Of course, when the number of voltage identification elements 123 is multiple groups, the first selection circuit 124 can be connected to some groups of voltage identification elements 123, the first output terminal 1241 of the first selection circuit 124 is connected to one identification terminal 1230, and the other part A group of voltage identification elements 123 can be directly connected to one identification terminal 1230 , so that the number of identification terminals 1230 is less than the number of groups of voltage identification elements 123 .

The electronic cigarette 1 of this embodiment can effectively reduce the number of identification terminals 1230 and signal terminals 1170 by setting the first selection circuit 124, so as to avoid too many circuits making the structure complex and easily lead to failure of the electronic cigarette 1, and simplifying the wiring can cut costs.

For the second case, part of each group of voltage identification elements 123 may be located in the cartridge 12, while the other part may be located in the smoking device 11. This embodiment can be specifically described as follows:

Referring to FIG. 5 , a part of the voltage identification element 123 is located in the smoking appliance 11 , and the other part is located in the cartridge 12 . Part of the voltage identification elements 123 located in the smoking appliance 11 and some of the voltage identification elements 123 located in the cartridge 12 jointly generate a voltage signal value. For example, when the smoking appliance 11 and the cartridge 12 are combined, part of the voltage identification element 123 located in the smoking appliance 11 communicates with or is electrically connected to a part of the voltage identification element 123 located in the cartridge 12, and the combination forms the voltage identification element 123, and the control circuit 117 obtains the voltage signal value from the voltage identification element 123 through the signal terminal 1170 .

Specifically, the voltage identification element 123 may include a first resistor 1231 and a second resistor 1232 , wherein part of the voltage identification element 123 located in the smoking appliance 11 includes the first resistor 1231 . One end of the first resistor 1231 is connected to the voltage source VDD, for example, the voltage source VDD can be the power supply circuit 116 of the smoking appliance 11, that is, one end of the first resistor 1231 is connected to the power supply circuit 116, for example, one end of the first resistor 1231 is connected to the power supply terminal 1160. The other end of the first resistor 1231 is connected to the signal end 1170 . When the electronic cigarette 1 includes multiple sets of voltage identification elements 123 , the first resistor 1231 of each set of voltage identification elements 123 can be connected to one signal terminal 1170 correspondingly. Part of the voltage identification element 123 located in the cartridge 12 includes a second resistor 1232 . One end of the second resistor 1232 is connected to the identification end 1230, and the other end of the second resistor 1232 is grounded. After the smoking device 11 and the pod 12 are combined, the first resistor 1231 and the second resistor 1232 form a loop through the identification terminal 1230 and the signal terminal 1170 , and a voltage division is generated at the end of the second resistor 1232 connected to the identification terminal 1230 . The control circuit 117 obtains the divided voltage value through the signal terminal 1170 and the identification terminal 1230 as a voltage signal value.

As shown in the connection relationship shown in Figure 5, the electronic cigarette 1 includes four sets of voltage identification elements 123, for example. The four second resistors 1232 of the spring 12 are correspondingly connected. Therefore, the control circuit 117 can obtain the divided voltage value of each group of voltage identification elements 123 through the correspondingly connected signal terminal 1170 and identification terminal 1230 , and combine the divided voltage values of each group of voltage identification elements 123 as a voltage signal value.

Certainly, for example, the voltage identification element 123 includes a first resistor 1231 and a second resistor 1232 , the first resistor 1231 is disposed in the cartridge 12 , and one end is connected to the voltage source VDD, and the other end is connected to the identification terminal 1230 . The second resistor 1232 is disposed in the smoking appliance 11, and one end is connected to the signal end 1110, and the other end is grounded.

In this embodiment, a part of the voltage identification element 123 is located in the cartridge 12, and a part is located in the smoking device 11, so that the cooperation between the smoking device 11 and the cartridge 12 can improve the anti-counterfeiting ability, and the split setting of the voltage identification element 123 can reduce the number of cigarette cartridges 12. The lower manufacturing cost enhances the adaptability between the cartridge 12 and the smoking device 11, thereby providing better and more suitable atomization conditions for the cartridge 12. In addition, it can effectively save the occupied space of each circuit or component in the pod 12, which is beneficial to reduce the volume of the pod 12, making the shape of the pod 12 more refined and beautiful, and the separate arrangement can effectively save the production cost of the pod 12 .

Regarding the third case, in the third case, the electronic cigarette 1 includes multiple sets of voltage identification elements 123, some of which are all located in the cartridge 12, and in other sets of voltage identification elements 123, each set Part of the voltage identification element 123 is located in the smoking device 11, and the other part is located in the cartridge 12. The combination of the voltage signal values of the multiple voltage identification elements is used to identify the type of the cartridge 12. It can be referred to and combined with the above-mentioned first situation and In the second case, again, no detailed introduction will be given.

For the voltage identification element 123, there may also be the following examples:

The voltage identification element 123 may include a plurality of resistors connected in series and connected between the voltage source VDD and the ground. The identification terminal 1230 can be connected between any two adjacent resistors among multiple resistors, and the connection point between any two adjacent resistors will generate a voltage division due to the voltage division effect of the resistors, and the identification terminal 1230 can be obtained partial pressure value. For example, each group of voltage identification elements 123 includes four resistors, which are A resistor, B resistor, C resistor, and D resistor in sequence from the voltage source VDD to the ground, then the identification terminal 1230 can be connected between the A resistor and the B resistor, or can be connected Between the B resistor and the C resistor, it can also be connected between the C resistor and the D resistor

When the electronic cigarette 1 includes multiple sets of voltage identification elements 123 , each set of voltage identification elements 123 can share a part of resistance, and each set of voltage identification elements 123 has another part of resistance respectively. For example, two groups of voltage identification elements 123 share A resistance and B resistance, and the resistance of another part of one group of voltage identification elements 123 is C1 resistance and D1 resistance, and the other part of resistance of another group of voltage identification elements 123 is C2 resistance and D2 resistance. .

As shown in FIG. 6 and FIG. 7 , for example, the electronic cigarette 1 includes a second selection circuit 125 . The second selection circuit 125 has a second controlled terminal 1250 , a second input terminal 1251 and a plurality of second output terminals 1252 . The control circuit 117 includes a control terminal 1171 for coupling to the second controlled terminal 1250 . The voltage identification element 123 includes a first resistor 1231 and a second resistor 1232. One end of the first resistor 1231 is coupled to the voltage source VDD, and the other end of the first resistor 1231 is respectively coupled to the second input terminal 1251 and the identification terminal 1230. One end of the two resistors 1232 is correspondingly connected to a second output end 1252 , and the other end of each second resistor 1232 is grounded.

The control circuit 117 is used to output a selection signal to the second selection circuit 125 through the second controlled terminal 1250. After the second selection circuit 125 receives the selection signal through the second controlled terminal 1250, it sequentially connects the first resistor 1231 and each The second resistor 1232 is used to generate a divided voltage at the other end of the first resistor 1231, so that the control circuit 117 can obtain the divided voltage value from each second resistor 1232, and the combination of the divided voltage value of each group of second resistors 1232 constitutes a voltage signal value.

Of course, if the second resistor 1232 is shared, the second selection circuit 125 can be provided with several second input terminals 1251 and second output terminals 1252 corresponding to the first resistors 1231 and the second resistors 1232 respectively. Certainly, some of the voltage identification elements 123 in the multiple groups of voltage identification elements 123 share the first resistor 1231 , and the part of the voltage identification elements 123 have their own second resistors 1232 , which are selectively connected through the second selection circuit 125 . The other partial voltage identification elements 123 have respective first resistors 1231 and second resistors 1232 . The numbers of identification terminals 1230 and signal terminals 1170 are set accordingly.

There may also be various situations regarding the arrangement of the voltage identification element 123 , for example, in the example shown in FIG. 6 , the voltage identification element 123 may be all arranged in the cartridge 12 . For example, in the example shown in Figure 7, a part of the voltage identification element 123 is set in the cartridge 12, and another part is set in the smoking appliance 11, for example, the first resistor 1231 is set in the smoking appliance 11, and the second resistor 1232 and the second selection The circuit 125 can be set in the cartridge 12 .

The working mode of the power supply circuit 116 includes, for example, whether to supply power, output voltage value, output power value, power supply duration and other related working parameters.

In some embodiments, when the type of the cartridge 12 does not meet the requirements, the control circuit 117 controls the power supply circuit 116 to not supply power to the heating circuit 121 or to supply power with low power. For example, when the cartridge 12 is combined with the smoking appliance 11 and the control circuit 117 does not obtain the voltage signal value of the cartridge 12, it can control the power supply circuit 116 to not supply power to the heating circuit 121 or supply power with low power. Alternatively, the control circuit 117 stores preset voltage signal values of various cartridges 12, and the control circuit 117 obtains the voltage signal value of the currently combined cartridge 12 to match with the stored voltage signal value. If it does not match, it can control The power supply circuit 116 does not supply power to the heating circuit 121 or supplies power with low power. Of course, the control circuit 117 can also obtain the preset voltage signal value from other places.

In this embodiment, power supply with low power means that the voltage value provided is lower than the voltage value for the normal operation of the heating circuit 121 , and/or the current value provided is lower than the current value for the normal operation of the heating circuit 121 . The purpose of setting the low battery power supply is to make the pod 12 that does not meet the requirements unable to work normally.

As shown in FIG. 5 , the smoking appliance 11 may also include a communication circuit 118 coupled to the control circuit 116 for communication with external devices (such as servers or terminals, and of course cloud servers), and the control circuit 116 may obtain data through the communication circuit 118 , such as voltage signal values of more types of pods 12 , so that the smoking device 11 can support more pods 12 . In other words, the control circuit 116 can update and replace the data through the communication circuit 118 , so as to update and replace the supported cartridges 12 .

Of course, the control circuit 116 can also obtain data related to the working mode through the communication circuit 118, so as to update, adjust, and replace the relevant data of the previous working mode, such as updating, adjusting, and replacing the corresponding output power value of a certain type of pod 12 , voltage value, etc., or add a new working mode (such as intermittent power supply mode, etc.). Of course, the control circuit 116 can also obtain new firmware through the communication circuit 118 to update the built-in program or software of the smoking appliance 11 .

Of course, the control circuit 116 can also send data through the communication circuit 118, such as the voltage signal value of the voltage identification element 123, etc., so as to track the pod 12 and the smoking set 11 more effectively, so as to facilitate after-sales service and anti-counterfeiting identification Wait.

In some implementations, the smoking appliance 11 may also include a human-computer interaction interface, such as a display screen or function buttons 115 in FIG. to suit their personal habits.

In some embodiments, the control circuit 117 may also include a warning circuit (not shown in the figure), and when the control circuit 117 detects that the type of the cartridge 12 does not meet the requirements, a warning message may be sent through the warning circuit. For example, the warning circuit is a voice broadcast circuit. When the type of the cartridge 12 does not meet the requirements, the control circuit 117 controls to turn on the voice broadcast circuit for voice broadcast prompts. Alternatively, the warning circuit can also be a display circuit, which can display warning information through display components connected to it, such as LED lamps, display screens, and the like.

In this embodiment, by controlling the power supply circuit 116 to work according to the working mode matching the type of the cartridge 12, after the smoking device 11 recognizes the cartridge 12, it can match the working mode most suitable for the cartridge 12 to facilitate personalized control of the cartridge 12 , to more effectively utilize the characteristics of the pod 12, thereby improving the taste of the pod 12.
