Two ends of each detection resistor are electrically connected to two contact elements 32, i.e. the number of the detection resistors plus one is equal to the number of the contact elements 32. Each detection resistor can be composed of a plurality of resistors connected in series or in parallel, namely the number of the detection resistors in the physical sense is variable, but the detection resistor of the application refers to the resistance value formed by all resistors of which two adjacent contact pieces 32 are connected at two ends; i.e. the R1 or R2 … Rn may comprise several resistors connected in series or parallel, respectively. The voltage detection module may be a plurality of switch circuits (such as a triode, etc.), and different voltages conduct the heating circuit to heat the atomizing core of the cartridge 10.
Hereinafter, description will be made on a case where the maximum number of the conductive members 22 is 3 and the resistance values of the first to n-th detection resistors are not equal to each other:
when the cartridge 10 is not provided with the conductive elements 22 or the number of conductive elements 22 is 1 (as shown in fig. 1), such a cartridge 10 represents a taste one; the detection voltage obtained by the voltage switch module V is the voltage at two ends of the detection resistors R1 and R2, and at this time, the detection voltage is conducted to the heating circuit corresponding to the first flavor of the cartridge to heat and atomize the atomization core in the cartridge 10;
when the cartridge 10 is provided with 2 electrically connected conductive elements 22 (as shown in fig. 2) at two ends corresponding to the detection resistor R1, the cartridge 10 has a second taste; the detection voltage obtained by the voltage switch module V is the voltage at two ends of the detection resistor R2, and at this time, the detection voltage is conducted to the heating circuit corresponding to the second cartridge taste to heat and atomize the atomization core in the cartridge 10; at this time, the detection resistor R1 is shorted by the two conductive members 22 through the corresponding two contact members 32, that is, at this time, the detection resistor R1 is regarded as not present;

Hereinafter, description will be made on a case where the maximum number of the conductive members 22 is 3 and the resistance values of the first to n-th detection resistors are equal:
in this case, the shorting detection resistors R1 and R2 have the same effect, so that only three shorting modes as shown in fig. 1, 2, 3, and 4 can distinguish the cartridges 10 of three flavors.
The maximum number of conductive elements 22 may be increased depending on the number of flavors of the cartridge 10, while the number of flavors of the cartridge 10 may be increased.
The positions of the conductive members 22 of the cartridge of embodiment 1 of the present application are schematic positions, and may be changed arbitrarily, and finally, the conductive members 22 connected to two ends of different detection resistors are used as targets, that is, the short circuit detection resistor R1 does not have to be conductive members at the first and second positions, and the conductive members at the second and third positions may be short-circuited R1 by changing internal connection lines. The first to third positions are non-fixed.
The detection circuit can be directly integrated on the microcontroller, is simple and convenient, has low cost compared with a cartridge identification method such as an acousto-optic sensor, can realize automatic control, and can realize identification after the cartridge is inserted into the tobacco rod.
Example 2

Hereinafter, description will be made in a state where the maximum number of conductive members 22 is 2:
as shown in fig. 6A, when the conductive members 22 are sequentially provided with 2 conductive members 22, which are respectively in contact with the contact members of the cigarette rod, the low level is transmitted to the contact members of the cigarette rod, and the number 0 is indicated, namely, the taste type of the cigarette cartridge is 0 type; the contact piece transmits the 0 type cartridge taste represented by 2 low-level signals to the judging module, and the judging module controls the corresponding heating circuit to heat the atomizer of the cartridge according to the signals;
as shown in fig. 6B, the conductive member 22 is disposed at a first position of two positions arranged in sequence, the second position is empty or the conductive member is disposed, but the conductive member at the second position is not grounded. At this time, the electric signals transmitted by the conductive piece are sequentially low level and high level, and represent the number 1, namely the type 1 of the flavor of the cartridge;
as shown in fig. 6C, the conductive member 22 is disposed at a second position of the two positions arranged in sequence, the first position is empty or the conductive member is disposed, but the conductive member at the first position is not grounded. At this time, the electric signals transmitted by the conductive piece are sequentially high level and low level, and represent the number 2, namely the type 2 of the flavor of the cartridge;
as shown in fig. 6D, the conductive member 22 is not provided with the conductive member 22 or provided with the conductive member at two positions arranged in sequence, but the conductive member is not grounded. At this time, the electric signals transmitted by the conductive elements 22 are all high level, which indicates the number 3, namely indicates the type 3 of the flavor of the cartridge;
as above, when the matching number of the conductive member 22 and the contact member 32 is 2, it is possible to recognize a taste of 4 types of cartridges at maximum. When the number of conductive elements 22 increases to 3, up to 8 types of cartridge flavors can be identified. And so on. Therefore, embodiment 2 can identify more cartridge flavor types with a smaller number of conductive elements 22.
In terms of structural design, for convenience of manufacturing versatility, as many conductive elements 22 as 2, 3, etc. may be disposed on each cartridge; however, only the conductive member 22 is selected to be grounded, and the conductive member 22 can be directly conducted with the negative electrode 21 on the cartridge when grounded, and at this time, a conductive cap is provided, so that the conductive member 22 required to be conducted with the negative electrode 21 is electrically conducted through the conductive cap.
Alternatively, the conductive member 22 may be formed integrally with the negative electrode, i.e., a member including the negative electrode and the conductive member 22 is formed by one metal member.
The position of the conductive member 22 of the cartridge according to embodiment 2 of the present application is a schematic position, and any transformation may be performed, and the position of the conductive member 22 may be determined by determining a binary level, for example, the first position may be a binary first position, and the second position may be a binary second position, or vice versa.
In this embodiment 2, the number of the contacts 32 of the stem is set on the cartridge 10 to transmit the low-level signal to the contacts, so that the number of the cartridge tastes is indicated by the number of the arranged combination types of the unequal number of the conductive elements 22, and the structure is simple and the cost is low.
The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and variations of the present application will be apparent to those skilled in the art.
