The main body 100B may include a control circuit 27 , a verification circuit 28 , a switch circuit 29 , and a resistor R. The control circuit 27 is electrically connected to the verification circuit 28 and the switch circuit 29 . The verification circuit 28, the switch circuit 29, and the resistor R are electrically connected to the same contact point a. The control circuit 27 and the verification circuit 28 are electrically connected to the same contact point c. Contact c is connected to the reference voltage.

In this case, the integrated control circuit 27 and verification circuit 28 can transmit signals/commands to the cartridge 100A via the contact a. The cartridge 100A can transmit signal/data information to the integrated control circuit 27 and the verification circuit 28 via the contact b.

The switch circuit 29 can be used to control the atomizing heating function of the atomizing device 100 .

One end of the resistor R is electrically connected to the power supply Vbat of the atomizing device 100, and the other end is electrically connected to the contact point a. The resistance R can be used to determine whether the cartridge 100A is electrically connected to the main body 100B. Specifically, when the cartridge 100A is not electrically connected to the main body 100B, the contact point a is at a high level; and when the cartridge 100A is electrically connected to the main body 100B, due to the access of the cartridge 100A, the contact point a turns to a low voltage flat; thereby it can be determined whether the cartridge 100A is electrically connected to the main body 100B.

The verification circuit 31 can be used to control the switching circuit 30 to be turned on and off. In an embodiment of the present application, the switch circuit 30 is in an off state, and the switch circuit 30 is turned on only when an on signal from the verification circuit 31 is received. In an embodiment of the present application, the verification circuit 31 of the cartridge 100A turns on the switch circuit 30 only after receiving the control signal S2 from the verification circuit 28 of the main body 100B. The control signal S2 and the control signal S3 may include different instructions/information transmitted from the main body 100B to the cartridge 100A. In some embodiments, the control signal S2 and the control signal S3 may include the first command, the second command, the third command, the fourth command and the fifth command mentioned in the following paragraphs.

Therefore, the verification of the main body 100B by the cartridge 100A can be realized. That is, when the main body 100B and the cartridge 100A do not match (for example, they do not belong to the same brand), the main body 100B does not have the function of generating the control signal S2 or the control signal S3, so the switch circuit 30 of the cartridge 100A cannot be driven to be normally driven by Open becomes closed. Therefore, the verification of the main body 100B by the cartridge 100A is realized.

The heating circuit 32 can be used to atomize and heat the e-liquid in the cartridge 100A. In one embodiment of the present application, the heating circuit 32 may be a resistive heating circuit. However, those skilled in the art can understand that the heating circuit 32 can also be in other forms, as long as it can realize atomization and heating of the e-liquid in the cartridge 100A, which is not limited here.

When the cartridge 100A is connected to the main body 100B, the contact b of the cartridge 100A is electrically connected to the contact a of the main body 100B, and the contact d of the cartridge 100A is electrically connected to the contact c of the main body 100B. Thus, the verification circuit 31 can receive the control signal S2 from the verification circuit 28, and turn on the switch circuit 30 in response to the control signal S2.

In some embodiments of the present application, the verification circuit 31 may send data information to the contact a via the contact b, and the control circuit 27 generates the control signal S1 in response to the comparison result between the data information and the reference data information.

In some embodiments of the present application, the data information and the reference data information include at least one of the flavor of e-liquid, the number of mouths that have been inhaled, a production number, and factory information.

In addition, in some embodiments of the present application, the atomizing device may further include other circuits, such as a power protection circuit, a charging management circuit, a status indication circuit, and a storage circuit, and the like. These circuits can be any form of circuits with the same functions existing in the prior art, which are not specifically limited herein.

FIG. 6 illustrates a verification method of an atomizing device according to some embodiments of the present application. The following steps 610 to 618 are the process for the main body 100B to verify the cartridge 100A.

Specifically, in step 610, the main body 100B is not connected to the pod 100A, at this time the main body 100B is in a static mode, and the switch circuit 29 is in an off state.

In step 612, once the cartridge 100A is connected to the main body 100B, the control circuit 27 is woken up in response to the interrupt wake-up signal.

In step 614 , the awakened control circuit 27 establishes a connection with the cartridge 100A via the verification circuit 28 , and sends the encrypted first command to the verification circuit 31 of the cartridge 100A through the verification circuit 28 . Wherein, the first instruction instructs the pod 100A to feed back first data information for verifying the pod 100A. The first data information includes at least one of the flavor of the e-liquid, the number of mouths that have been inhaled, a production number, and factory information. When the verification circuit 31 of the cartridge 100A receives the encrypted first instruction, it decrypts the first instruction and feeds back the first data information to the control circuit 27 via the verification circuit 28 .

In step 616, the control circuit 27 waits for the first data information from the cartridge 100A; if the first data information from the cartridge 100A is not received, the control circuit 27 returns to step 614; 100A first data information, then go to step 618 .

After receiving the first data information from the cartridge 100A, in step 618, compare the received first data information with the reference data information stored in the memory; if the two are not the same, it means the cartridge 100A is an invalid cartridge 100A, then a warning signal is issued in step 619 to remind the user that the cartridge 100A cannot work normally, and go back to step 610 to restart the verification method of the atomizing device; if the two are the same, it means that the The first data information returned by the cartridge 100A is valid cartridge information, that is, the main body 100B verifies the validity of the cartridge 100A, thereby entering the smoking control mode.

Among them, the memory can be set in the control circuit 27, or can be set in the main body 100B separately; the reference data information includes at least one of the taste of e-liquid, the number of mouths that have been inhaled, the production number and the factory information; the warning signal can be flashing lights, etc. Obvious sign form; puff control mode includes step 620 and step 622.

After verifying the validity of the cartridge 100A, in step 620 , the main body 100B sends the second instruction and the third instruction to the cartridge 100A via the control circuit 27 . In some embodiments, the control circuit 27 may send the second command and the third command to the cartridge 100A via the verification circuit 28 . In some embodiments, the control circuit 27 may directly send the second command and the third command to the cartridge 100A. For example, the control circuit 27 can directly send the second command and the third command to the cartridge 100A by opening the switch circuit 29 into a channel.

The second instruction instructs the pod 100A to turn on the switch circuit 30 of the pod 100A, and the third instruction instructs the pod 100A to feed back second data information for verifying the pod 100A. The second data information includes at least one of the flavor of the e-liquid, the number of mouths that have been smoked, the production number, and the factory information.

At the end of the cartridge 100A, it receives the second command and the third command from the main body 100B, turns on the switch circuit 30, and feeds back the second data information to the control circuit 27 of the main body 100B.

In step 622, the main body 100B receives the second data information from the cartridge 100A, and compares the second data information with the reference data information; when the second data information is not the same as the reference data information, go back to step 620, and A warning signal is issued; when the second data information is the same as the reference data information, the main body 100B enters the atomization heating mode. The warning signal can be in the form of obvious signs such as flashing lights; the atomization heating mode includes steps 624 to 630 .

In the above puff control mode (ie steps 620 and 622 ), the purpose of requiring the cartridge 100A to return the second data information to the main body 100B is: the cartridge 100A and the main body 100B are detachably connected; Compared with other methods, the detachable connection may cause the pod 100A to be disconnected from the main body 100B after being subjected to external interference (such as vibration, etc.); therefore, in steps 620 and 622, the main body 100B verifies the effectiveness of the pod 100A again. sex. However, it should be understood that the steps of the main body 100B verifying the validity of the cartridge 100A again in steps 620 and 622 may be omitted, but not required. That is, the main body 100B can only send the second command instructing the cartridge 100A to turn on the switch circuit 30 of the cartridge 100A, and after receiving the second command, the cartridge 100A only needs to turn on the switch circuit 30 without returning the second data The information is given to the control circuit 2 of the main body 100B.

After it is verified that the second data information is the same as the reference data information, in step 624, the main body 100B detects whether the user has a suction action. When the user's puffing action is not detected, go back to step 624 until the user's puffing action is detected; when the user's puffing action is detected, go to step 626 .

In step 626, the control circuit 27 of the main body 100B turns on the switch circuit 29 to realize the electrical connection between the power supply Vbat of the main body 100B and the heating circuit 32 of the cartridge 100A, thereby realizing atomization heating.

In step 628, when the control circuit 27 of the main body 100B detects the end of the user's puffing action, the switch circuit 29 is turned off, and the electrical connection between the power supply Vbat of the main body 100B and the heating circuit 32 of the cartridge 100A is interrupted, thereby stopping the atomization heating .

In step 630 , the control circuit 27 of the main body 100B sends specific data information to the pod 100A via the verification circuit 28 ; the pod 100A receives and stores the specific data information, and turns off the switch circuit 30 at the same time. Wherein, the specific data information may be, but not limited to, the number of inhaled mouths.

Steps 610 to 618 are the process of verifying the cartridge 100A by the main body 100B, which realizes the verification of the cartridge 100A by the main body 100B. In addition, since the switch circuit 30 is initially in an off state, the switch circuit 30 is turned on only when the turn-on signal from the verification circuit 31 is received, so that the atomizing heating function can be realized; that is, when the main body 100B is not connected to the When the cartridge 100A is matched, since the main body 100B cannot turn on the switch circuit 30 of the cartridge 100A, the atomization heating of the e-liquid in the cartridge 100A cannot be realized; that is, the verification of the main body 100B by the cartridge 100A is realized. . Thus, the two-way anti-counterfeiting of the main body 100B and the cartridge 100A is realized.

FIG. 7 illustrates a verification method of an atomizing device according to other embodiments of the present application. Wherein, steps 710 to 719 are the same process of verifying the cartridge 100A by the main body 100B as steps 610 to 619 in FIG. 6 , and details are not repeated here.

Steps 720 and 722 are puff control modes. When the control circuit 27 determines that the pod 100A is valid, in step 720, the control circuit 27 of the main body 100B sends a second command to the pod 100A, wherein the second instruction instructs the pod 100A to feed back the second command used to verify the pod 100A. Data information. The second data information includes at least one of the flavor of the e-liquid, the number of mouths that have been smoked, the production number, and the factory information. At the end of the cartridge 100A, the cartridge 100A receives the second instruction from the main body 100B, and feeds back second data information.

In step 722, the control circuit 27 of the main body 100B receives the second data information from the cartridge 100A, and compares the second data information with the reference data information. Wherein, the reference data information includes at least one of the flavor of the e-liquid, the number of mouths that have been inhaled, the production number, and the factory information. When the second data information is different from the reference data information, go back to 720; when the second data information is the same as the reference data information, enter the second verification process. Compared with steps 620 and 622, the switch circuit 30 of the cartridge 100A is not turned on in steps 720 and 722. Therefore, the atomization device cannot enter the atomization heating mode, and the cartridge needs to be checked again for the second time.

The second verification process includes steps 724 to 732 .

In step 724 , the main body 100B detects through the control circuit 27 whether the user has a suction action; when no suction action is detected, go back to 724 ; when a suction action is detected, go to step 726 .

In step 726, the control circuit 27 sends the encrypted fourth command to the verification circuit 31 of the cartridge 100A via the verification circuit 28, wherein the fourth command instructs the cartridge 100A to feed back the third data for verifying the cartridge 100A information. At the end of the cartridge 100A, it receives and decrypts the fourth instruction, and feeds back the third data information to the main body 100B.

In step 728, the main body 100B waits for the return data of the cartridge 100A; when the return data is not received, go back to 726; when the return data is received, go to step 730.

In step 730, the control circuit 27 of the main body 100B compares the received third data information with the reference data information; if the third data information is different from the reference data information, the control circuit 27 determines that the cartridge 100A is not a valid cigarette If the third data information is the same as the reference data information, then go to step 732. Among them, the warning signal may be in the form of obvious signs such as flashing lights.

In step 732 , the control circuit 27 determines that the pod 100A is a valid pod, and at this time, the control circuit 27 sends a fifth command to the pod 100A; the fifth instruction instructs the pod 100A to turn on the switch circuit 30 . At the end of the cartridge 100A, the cartridge 100A receives the instruction and turns on its switch circuit 30 . So far, the second verification process is completed. Next, enter the atomization heating mode. The atomization heating mode includes steps 734 to 738 .

In step 734, the control circuit 27 turns on the switch circuit 29, and in response to the user's puffing action, the heating circuit 32 atomizes and heats the e-liquid in the cartridge 100A.

In step 736, when the control circuit 27 detects the end of the user's puffing action, it closes the switch circuit 29 and interrupts the electrical connection between the power supply Vbat of the main body 100B and the heating circuit 32 of the cartridge 100A, thereby stopping the atomization heating.

In step 738 , the control circuit 27 of the main body 100B sends specific data information to the pod 100A via the verification circuit 28 ; the pod 100A receives and stores the specific data information, and turns off the switch circuit 30 at the same time. Wherein, the specific data information may be, but not limited to, the number of inhaled mouths.

Similar to steps 610 to 618 , steps 710 to 718 are the process of verifying the cartridge 100A by the main body 100B, which realizes the verification of the cartridge 100A by the main body 100B. In addition, since the switch circuit 30 is initially in an off state, the switch circuit 30 is turned on only when the turn-on signal from the verification circuit 31 is received, so that the atomizing heating function can be realized; that is, when the main body 100B is not connected to the When the cartridge 100A is matched, since the main body 100B cannot turn on the switch circuit 30 of the cartridge 100A, the atomization heating of the e-liquid in the cartridge 100A cannot be realized; that is, the verification of the main body 100B by the cartridge 100A is realized. . Thus, the two-way anti-counterfeiting of the main body 100B and the cartridge 100A is realized.

In addition, while realizing two-way anti-counterfeiting, the atomizing device of the embodiment of the present application can also realize the two-way connection between the main body 100B and the pod 100A by using only two contacts b and d without increasing the contacts of the pod 100A.
