Figure 2A illustrates a front view of a cartridge according to some embodiments of the present application. Figure 2B illustrates a side view of a cartridge according to some embodiments of the present application. Figure 2C illustrates a top view of a cartridge according to some embodiments of the present application. Figure 2D illustrates a bottom view of a cartridge according to some embodiments of the present application.

Fig. 5 illustrates a block diagram of internal circuitry of an atomization device according to some embodiments of the present application. As shown in fig. 1A-1B and 5, the aerosolization device 100 includes a body 100B and a cartridge 100A.

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 a. The control circuit 27 and the verification circuit 28 are electrically connected to the same contact point c. Contact c is connected to a reference voltage. In the present application, the reference voltage is the ground voltage GND.

The body 100B and the cartridge 100A may communicate with each other via a contact a, a contact B, a contact c, and a contact d. Commands, data information, signals, voltages, currents, power, or electrical power may be communicated between the body 100B and the cartridge 100A via contacts a, B, c, and d.

The control circuit 27 may be, but is not limited to, a microcontroller, a microprocessor, a single chip controller, or the like. Control circuitry 27 may send control signal S1 to verification circuitry 28. The verification circuit 28 may receive the control signal S1 from the control circuit 27 and generate a control signal S2. The control signal S2 generated by the verification circuit 28 may be transmitted to the contact b of the cartridge 100A via the contact a.

The control circuit 27 may pass the control signal S3 directly to the cartridge 100A. In some embodiments, the control circuit 27 may turn on the switch circuit 29, so that the control circuit 27 is in communication with the contact a, and transmit the control signal S3 to the contact b of the cartridge 100A via the contact a. The cartridge 100A may transmit data information to the body 100B in response to the control signal S2 or the control signal S3 from the body 100B.

In some embodiments, the control circuit 27 and the verification circuit 28 may be integrally packaged within the same Integrated Chip (IC). In this case, the integrated control circuit 27 and verification circuit 28 may transmit signals/commands to the cartridge 100A via contact a. The cartridge 100A may transmit signal/data information to the integrated control circuit 27 and verification circuit 28 via contact b.

The switching circuit 29 may be used to control the atomizing heating function of the atomizing device 100. The control circuit 27 may be used to control the switch circuit 29 to be turned on or off, thereby turning on or off the atomizing heating function of the atomizing device 100. In particular, the control circuit 27 may turn the switching circuit 29 on or off in response to a pumping action by the user. One end of the resistor R is electrically connected to the power supply Vbat of the atomizer 100, and the other end is electrically connected to the contact a. The resistance R may be used to determine whether the cartridge 100A is electrically connected to the body 100B. Specifically, when the cartridge 100A is not electrically connected to the main body 100B, the contact a is at a high level; when the cartridge 100A is electrically connected to the body 100B, the contact a is turned low due to the insertion of the cartridge 100A; whereby it can be determined whether the cartridge 100A is electrically connected to the main body 100B. The resistance of the resistor R may be, but is not limited to, 1K to 10K.

The cartridge 100A may include a switching circuit 30, a verification circuit 31, and a heating circuit 32. The switch circuit 30 is electrically connected to the verification circuit 31 and the heating circuit 32. The verification circuit 31 and the heating circuit 32 are electrically connected to the same contact b. The inspection circuit 31 and the switch circuit 30 are electrically connected to the same contact d. The junction d is connected to a reference voltage. In the present application, the reference voltage is the ground voltage GND.

The verification circuit 31 may be used to control the switching on and off of the switching circuit 30. In one 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 is received from the verification circuit 31. In one embodiment of the present application, the verification circuitry 31 of the cartridge 100A turns on the switch circuitry 30 after receiving the control signal S2 from the verification circuitry 28 of the main body 100B. The control signals S2 and S3 may include different instructions/information that are transmitted by the body 100B to the cartridge 100A. In some embodiments, the control signals S2 and S3 may include the first, second, third, fourth, and fifth instructions mentioned in the subsequent paragraphs.

Thus, verification of the cartridge 100A to the body 100B may be achieved. That is, when the main body 100B does not match (e.g., does not belong to the same brand) the cartridge 100A, the main body 100B does not have the function of generating the control signal S2 or the control signal S3, and thus the switch circuit 30 of the cartridge 100A cannot be driven to change from normally open to closed. Thus, verification of the cartridge 100A to the body 100B is achieved.

The heating circuit 32 may be used to atomize and heat the tobacco tar in the cartridge 100A. In one embodiment of the present application, the heating circuit 32 may be a resistive heating circuit. However, one skilled in the art will understand that: the heating circuit 32 may also be in other forms as long as it can achieve the atomization heating of the tobacco tar in the cartridge 100A, and is not limited herein.

When the cartridge 100A is attached to the body 100B, the contact B of the cartridge 100A is electrically connected to the contact a of the body 100B, and the contact d of the cartridge 100A is electrically connected to the contact c of the body 100B. Thus, the check circuit 31 may receive the control signal S2 from the check 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 the 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 a flavor of the tobacco tar, a number of sucked ports, a production number, and factory information.

In addition, in some embodiments of the present application, the control circuit 27, the verification circuit 28, the switch circuit 29, the resistor R, and the power supply of the main body 100B may be disposed on the main control module 17 shown in fig. 4A and 4B; the verification circuit 31, the switch circuit 30, and the heating circuit 32 of the cartridge 100A may be disposed on the circuit board 7 shown in fig. 3A and 3B.

Additionally, in some embodiments of the present application, the atomization device may also include other circuitry, such as: the charging management circuit comprises a power supply protection circuit, a charging management circuit, a state indicating circuit, a storage circuit and the like. These circuits may be any type of circuits having the same function as those in the prior art, and are not particularly limited herein.

Fig. 6 illustrates a method of verifying a nebulizing device according to some embodiments of the present application. The following steps 610-618 are the process of the body 100B authenticating the cartridge 100A.

Specifically, in step 610, the main body 100B does not access the cartridge 100A, and the main body 100B is in the static mode and the switch circuit 29 is in the off state.

In step 612, the cartridge 100A, once accessed to the body 100B, at which point the control circuit 27 wakes 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 via the verification circuit 28. Wherein the first instruction instructs the cartridge 100A to feed back first data information for verifying the cartridge 100A. The first data information includes at least one of a flavor of the tobacco tar, a number of sucked portions, a production number, and factory information. When the verification circuit 31 of the cartridge 100A receives the encrypted first command, it decrypts the first command 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 whether there is first data information from the cartridge 100A; if the first data information is not received from the cartridge 100A, the control circuit 27 returns to step 614; if the first data information is received from the cartridge 100A, step 618 is entered.

Upon receiving the first data information from the cartridge 100A, the received first data information is compared with reference data information stored in memory in step 618; if the two are different, the cartridge 100A is an invalid cartridge 100A, then a warning signal is sent in step 619 to remind the user that the cartridge 100A cannot work normally, and the process returns to step 610 to restart the verification method of the atomization device; if the two are the same, the first data information returned by the cartridge 100A is the valid cartridge information, i.e., the main body 100B verifies the validity of the cartridge 100A, thereby entering the smoking control mode.

The memory may be provided in the control circuit 27, or may be provided separately in the main body 100B; the reference data information comprises at least one of tobacco flavor, sucked mouth number, production number and factory information; the warning signal can be in the form of obvious signs such as light flicker; the pumping control mode includes

steps

620 and 622.

When the validity of the cartridge 100A is verified, the main body 100B sends a second command and a third command to the cartridge 100A via the control circuit 27 in step 620. In certain embodiments, the control circuitry 27 may send the second and third instructions to the cartridge 100A via the verification circuitry 28. In certain embodiments, the control circuitry 27 may send the second and third instructions directly to the cartridge 100A. For example, the control circuit 27 may send the second and third commands directly to the cartridge 100A by opening the switch circuit 29 into the path.

Wherein the second instruction instructs the cartridge 100A to open the switch circuit 30 of the cartridge 100A, and the third instruction instructs the cartridge 100A to feed back the second data information for verifying the cartridge 100A. The second data information includes at least one of a taste of the tobacco tar, a number of sucked portions, a production number, and factory information.

At 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, returning to the step 620 and sending an alarm signal; when the second data information is the same as the reference data information, the main body 100B enters the atomizing heating mode. The warning signal can be in the form of obvious signs such as light flicker; the atomization heating mode includes steps 624 through 630.

In the above smoking control mode (i.e., steps 620 and 622), the purpose of requiring the cartridge 100A to return the second data information to the main body 100B is to: the cartridge 100A and the main body 100B are detachably connected; compared with the non-detachable connection manner, the detachable connection may disconnect the cartridge 100A from the main body 100B after being subjected to external interference (e.g., vibration, etc.); thus, the main body 100B again verifies the validity of the cartridge 100A in

steps

620 and 622. However, it should be understood that the steps of the body 100B verifying the validity of the cartridge 100A again in

steps

620 and 622 may be omitted and are not required. That is, the main body 100B may send only the second instruction instructing the cartridge 100A to turn on the switch circuit 30 of the cartridge 100A, and after the cartridge 100A receives the second instruction, only the switch circuit 30 needs to be turned on without returning the second data information to the control circuit 2 of the main body 100B.

When it is verified that the second data information is identical to the reference data information, the main body 100B detects whether the user has a pumping action in step 624. When no user's pumping action is detected, go back to step 624 until a user's pumping action is detected; when a user's pumping action is detected, step 626 is entered.

In step 626, the control circuit 27 of the main body 100B turns on the switch circuit 29 to electrically connect the power supply Vbat of the main body 100B to the heating circuit 32 of the cartridge 100A, thereby achieving the atomizing heating.

In step 628, when the control circuit 27 of the main body 100B detects the end of the suction action of the user, the switch circuit 29 is turned off, and the power supply Vbat of the main body 100B is electrically disconnected from the heating circuit 32 of the cartridge 100A, thereby stopping the atomizing heating.

In step 630, the control circuit 27 of the main body 100B sends the specific data information to the cartridge 100A via the verification circuit 28; the cartridge 100A receives and stores the specific data information while the switching circuit 30 is turned off. The specific data information may be, but is not limited to, the number of sucked ports.

Steps 610 through 618 validate the cartridge 100A for the body 100B, enabling verification of the cartridge 100A by the body 100B. In addition, since the switch circuit 30 is initially in the off state, the switch circuit 30 is turned on only when receiving the on signal from the verification circuit 31, so that the atomizing heating function can be realized; that is, when the main body 100B is not mated with the cartridge 100A, since the main body 100B cannot turn on the switch circuit 30 of the cartridge 100A, the atomizing heating of the tobacco tar in the cartridge 100A cannot be achieved; that is, the verification of the cartridge 100A to the body 100B is achieved. Thus, the two-way forgery prevention of the main body 100B and the cartridge 100A is realized.

FIG. 7 illustrates a method of verifying an aerosolization device according to further embodiments of the present application. Here, 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 are not described again here.

Steps

720 and 722 are pumping control modes. When the control circuit 27 determines that the cartridge 100A is valid, in step 720, the control circuit 27 of the main body 100B sends a second instruction to the cartridge 100A, wherein the second instruction instructs the cartridge 100A to feed back second data information for verifying the cartridge 100A. The second data information includes at least one of a taste of the tobacco tar, a number of sucked portions, a production number, and factory information. At the cartridge 100A end, the cartridge 100A receives the second command 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 flavor of tobacco tar, number of sucked ports, production number and factory information. When the second data information is not the same as the reference data information, go back to 720; and entering a second checking process when the second data information is the same as the reference data information. In contrast to

steps

620 and 622, the switching circuit 30 of the cartridge 100A is not turned on in

steps

720 and 722. Therefore, the atomizing device cannot enter the atomizing heating mode, and the cartridge needs to be subjected to a second verification process again.

The second verification process includes steps 724 through 732.

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

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

In step 728, the main body 100B waits for return data of the cartridge 100A; when no return data is received, go back to 726; when return data is received, step 730 is entered.

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 not the same as the reference data information, the control circuit 27 determines that the cartridge 100A is not a valid cartridge, sends an alert signal, and returns to step 710 to resume the step of verifying the aerosolization device; if the third data information is the same as the reference data information, step 732 is entered. Wherein, the warning signal can be in the form of obvious signs such as light flicker.

In step 732, the control circuit 27 determines that the cartridge 100A is a valid cartridge, at which point the control circuit 27 sends a fifth instruction to the cartridge 100A; the fifth instruction instructs the cartridge 100A to open the switch circuit 30. At the cartridge 100A end, the cartridge 100A receives the command and turns on its switching circuit 30. So far, the second verification process is completed. Then, the atomization heating mode is entered. The atomizing heating pattern includes steps 734 to 738.

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

In step 736, when the control circuit 27 detects the end of the user's smoking action, the switch circuit 29 is closed, 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 aerosol heating.

In step 738, the control circuit 27 of the main body 100B sends the specific data information to the cartridge 100A via the verification circuit 28; the cartridge 100A receives and stores the specific data information while the switching circuit 30 is turned off. The specific data information may be, but is not limited to, the number of sucked ports.

Like steps 610-618, steps 710-718 validate the cartridge 100A for the body 100B, enabling verification of the cartridge 100A by the body 100B. In addition, since the switch circuit 30 is initially in the off state, the switch circuit 30 is turned on only when receiving the on signal from the verification circuit 31, so that the atomizing heating function can be realized; that is, when the main body 100B is not mated with the cartridge 100A, since the main body 100B cannot turn on the switch circuit 30 of the cartridge 100A, the atomizing heating of the tobacco tar in the cartridge 100A cannot be achieved; that is, the verification of the cartridge 100A to the body 100B is achieved. Thus, the two-way forgery prevention of the main body 100B and the cartridge 100A is realized.

In addition, while realizing two-way anti-counterfeiting, the atomization device of the embodiment of the application can realize the two-way verification function of the main body 100B and the cartridge 100A by only utilizing the two contacts B and the two contacts d under the condition that the contacts of the cartridge 100A are not increased. Specifically, in conjunction with fig. 3A-3B and fig. 6-7, contact B may correspond to metal component 9a in fig. 3A and 3B; the contact d may correspond to the metal component 9B in fig. 3A and 3B. Thus, the cartridge 100A end can perform a two-way verification function with only 2 contacts.
