The heater may, for example, comprise a combustible material, a material that can be heated by electrical conduction, or a sensor.

[0108] A sensor is a material that can be heated by being penetrated by a changing magnetic field (e.g., an alternating magnetic field). A sensor can be a conductive material, such that penetration by a changing magnetic field results in inductive heating of the heating material. A heating material can be a magnetic material, such that penetration by a changing magnetic field results in hysteresis heating of the heating material. A sensor can be both conductive and magnetic, allowing it to be heated by both heating mechanisms. In this paper, a device constructed to generate a changing magnetic field is referred to as a magnetic field generator.

[0109] Aerosol modifiers are substances typically located downstream of the aerosol generation region, configured to modify the generated aerosols, for example, by altering their taste, flavor, acidity, or other properties.

For example, aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. For example, aerosol modifiers can be solid, liquid, or gel. Aerosol modifiers can be in powder, filament, or granular form. Aerosol modifiers may not contain filter material.

[0110] An aerosol generator is a device configured to cause the generation of aerosols from an aerosol-generating material. In some embodiments, an aerosol generator is a heater configured to subject the aerosol-generating material to heat energy in order to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, an aerosol generator is configured to cause the generation of aerosols from an aerosol-generating material without heating. For example, an aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0111] This disclosure relates to aerosol supply systems (which may also be referred to as vapor supply systems), such as aerosol sprayers or electronic cigarettes. In the following description, the terms "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term is used interchangeably with aerosol supply systems / devices and electronic aerosol supply systems / devices. Furthermore, as is common in the art, the terms "aerosol" and "vapor," as well as related terms such as "evaporation," "atomization," and "aerosolization," are generally used interchangeably.

[0112] Aerosol supply systems (electronic cigarettes) typically (though not always) comprise modular components, including reusable device parts and replaceable (disposable / consumable) cartridge components. Typically, the replaceable cartridge component will include aerosol generating material and an vaporizer (which may be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power source) and control circuitry. It will be understood that these different parts may include additional components depending on their function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge device part may include, in some cases, a temperature sensor to aid in temperature control. The cartridge is electrically and mechanically connected to the control unit for use, for example, using threads, bayonet connections, or magnetic connections with suitably arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part, and a replacement cartridge can be attached to its appropriate position. Systems and devices that conform to this type of two-piece modular configuration can generally be referred to as two-piece systems / devices.

[0113] Electronic cigarettes typically have a generally elongated shape. For the sake of specific examples, some embodiments of this disclosure will be considered to include such a generally elongated two-piece system employing a disposable cartridge. However, it will be understood that the basic principles described herein can be equally applied to different constructions, such as single-piece systems or modular systems comprising more than two components, refillable devices and single-use disposable items, as well as other overall shapes, such as high-performance devices based on so-called box-shaped patterns that are typically box-shaped. More generally, it will be understood that some embodiments of this disclosure are based on an aerosol delivery system operationally configured to provide the functionality according to the principles described herein, and the construction aspects of the system configured to provide the functionality according to some embodiments of this disclosure are not of primary importance.

[0114] As described in the background art, existing methods for obtaining information about an aerosol supply system require adding special chips or too many components to the system, which is costly and affects the system's heating efficiency. For example, if a certain circuit is always in a conductive state, it will consume part of the system's power supply voltage, affecting the heating efficiency. Based on this, the present invention proposes an information identification and control circuit for an aerosol supply system, which enables the aerosol supply system to identify relevant information at low cost without affecting the system's heating efficiency, so as to achieve the best control scheme for the system based on the relevant information.

[0115] Specifically, an information identification and control circuit for an aerosol supply system includes a first circuit and a second circuit. The first circuit includes a first identification resistor and a first capacitor connected in series. The second circuit includes a first control switch and a heating element connected in series. The relationship between the first and second circuits is as follows: when the first capacitor is charging, the first control switch is open; when the first capacitor is fully charged, the first control switch is closed, and the heating element starts heating. The purpose of this invention is to identify and obtain relevant system information through the identification resistor. Furthermore, since the heating element only starts heating after the series-connected capacitor is fully charged, the circuit with the identification resistor and capacitor does not consume power supply voltage after the heating element starts, thus not affecting the system's heating efficiency. At the same time, compared to adding special chips and numerous components, this invention only adds a resistor, capacitor, and control switch circuit, resulting in low cost and good performance.

[0116] In one implementation, refer to Figure 1 In the information recognition control circuit, the first circuit and the second circuit are connected in parallel. The two ends of the second circuit and the first circuit share the first electrical connection terminal 100 and the second electrical connection terminal 200. The first identification resistor and the first capacitor connected in series in the first circuit are connected to the first control switch, so that when the first capacitor is fully charged, the first control switch is turned on, that is, the first control switch is closed, the second circuit is formed, and the heating element is started. Since the first control switch is turned on after the first capacitor is fully charged, the first circuit is equivalent to an open circuit at this time, and does not consume the power supply voltage from the first electrical connection terminal 100 or the second electrical connection terminal 200, so it has no impact on the heating efficiency of the heating element. Furthermore, the first capacitor can be detected by its charging voltage through the first electrical connection terminal 100 or the second electrical connection terminal 200 to obtain the resistance value of the first identification resistor. For example, in a series circuit of a resistor and a capacitor, the resistance value of the series resistor can be calculated if the initial voltage, full-charge voltage, and charging voltage of the capacitor at a certain moment are known. In this example, only two power supply terminals are needed to obtain the resistance value. It should be understood that the resistance value can also be obtained by other methods, such as adding a chip to directly obtain the resistance value through the voltage and current of the resistor. The control circuit structure of this example is not a limitation on the way to obtain the resistance value.

[0117] In one implementation, refer to Figure 2 The information recognition control circuit also includes a third circuit, with its two ends connected to the first electrical connection terminal 100 and the second electrical connection terminal 200, respectively. The third circuit includes a second identification resistor and a second capacitor connected in series. When the first circuit is on, the third circuit is off; when the third circuit is on, the first circuit is off. That is, the first circuit and the third circuit have opposite conduction directions. Therefore, whether the first electrical connection terminal 100 or the second electrical connection terminal 200 is connected to voltage and the other end is grounded, the capacitor of the corresponding path can be charged to obtain the resistance value of the identification resistor of the corresponding path, thereby obtaining the corresponding information. Specifically, the first circuit further includes a first unidirectional conducting circuit, which is connected in series with a first identification resistor; the third circuit includes a second unidirectional conducting circuit, which is connected in series with a resistor in the second identification circuit. Through the design of the unidirectional conducting circuit, when the first electrical connection terminal 100 is connected to a positive voltage and the second electrical connection terminal 200 is grounded, the first unidirectional conducting circuit conducts to charge the first capacitor, and the resistance value of the first identification resistor can be obtained from the charging voltage of the first capacitor; when the second electrical connection terminal 200 is connected to a positive voltage and the first connection terminal 100 is grounded, the second unidirectional conducting circuit conducts to charge the second capacitor, and the resistance value of the second identification resistor can be obtained from the charging voltage of the second capacitor. In this invention, the first and second unidirectional conducting circuits can be diodes. It is important to note that when the first circuit is conducting, the heating element can be activated once the first capacitor is fully charged, without affecting the system's heating efficiency. When the third circuit is conducting, the resistance value of the second resistor can only be obtained through the supply voltage to the second capacitor via the second electrical connection terminal 200, and the heating element cannot be activated. After the second identification resistor is identified and its resistance value calculated, the directions of the voltage supplied to the first electrical connection terminal 100 and the second electrical connection terminal 200 can be reversed to obtain the resistance value of the first identification resistor and activate the heating element. Furthermore, the resistance value of the second identification resistor can be the same as that of the first identification resistor, serving as an identification resistor with the same information in another power supply direction; alternatively, the resistance value of the second identification resistor can be different from that of the first identification resistor, allowing different types of system information to be obtained from different circuits.

[0118] In one implementation, refer to Figure 3The information recognition and control circuit also includes a fourth circuit. This fourth circuit includes a second control switch, which is connected to the third circuit, the second electrical connection terminal 200, and the heating element. Specifically, the second control switch is connected between the second capacitor and the second identification resistor, so that when the second capacitor is charging, the second control switch is open; when the second capacitor is fully charged, the second control switch is closed, and the heating element starts heating. Based on this circuit, regardless of whether a positive voltage is applied to the first electrical connection terminal 100 or the second electrical connection terminal 200, the resistance value of the internal identification resistor can be measured through the capacitor. Simultaneously, when the capacitor is fully charged, the corresponding control switch can be turned on and the heating element can be started. Furthermore, regardless of which circuit with the identification resistor is active, the heating efficiency of the system will not be affected.

[0119] In the above embodiments, the resistance values ​​of the first identification resistor and the second identification resistor correspond to the information of the aerosol supply system. In this invention, the information of the aerosol supply system includes, but is not limited to, the flavor of the cigarette cartridge, the system ID, and authentication information. The first control switch and the second control switch can be MOSFETs. The entire information identification and control circuit does not require special chips. It only needs capacitors, resistors, and switching elements to realize the identified information without affecting the system heating system.

[0120] It is necessary to understand that Figures 1-3 This is merely a circuit schematic diagram and is not intended to convey the specific structure and component settings of each circuit. Other circuit architectures or related peripheral circuit designs that have the same function according to actual needs should also be within the scope of protection of this invention.

[0121] Furthermore, the present invention provides a cartridge for an aerosol supply system, including the information recognition and control circuit described above.

[0122] In one implementation, such as Figure 4 As shown, the first electrical connection terminal 100 is the first power supply pin of the cartridge, and the second electrical connection terminal 200 is the second power supply pin of the cartridge. The resistance value of the identification resistor in the cartridge can be obtained through these two power supply pins, thereby acquiring information about the cartridge, such as its flavor. This information is then used to optimize the power output of the heating element. Furthermore, regardless of which power supply pin of the cartridge is connected to a positive voltage, a circuit with an identification resistor and capacitor can be activated to obtain cartridge information without affecting the heating efficiency of the heating element. The specific structure and principle of the information identification control circuit within the cartridge are described in the above example of information identification control circuit; repetitions will not be repeated.

[0123] Furthermore, the present invention provides an aerosol supply system, the system comprising:

[0124] A cavity for containing materials that generate aerosols;

[0125] The information recognition control circuit as described above or the cigarette cartridge as described above;

[0126] A heating element is configured to heat the aerosol-generating material to generate an aerosol.

[0127] In one embodiment, the system includes a cartridge as described above and a reusable device terminal connected to the cartridge and having a power source, such as... Figure 5 As shown, the device includes a control circuit, a power supply, and a third power supply pin 300 and a fourth power supply pin 400 connected to the cartridge. The device also includes a measurement control circuit and a heating control circuit. When measuring the voltage of the power supply pins, the control circuit activates the measurement control circuit, and the power supply voltage of the third power supply pin 300 is collected and returned to the control circuit for calculating the resistance value of the identification resistor. When the device activates heating, the control circuit activates the heating control circuit, which heats the cartridge through the third power supply pin 300. It is important to understand that because both power supply pins in the cartridge are connected to a conductive identification resistor circuit, the resistance value of the corresponding identification resistor in the cartridge can be obtained regardless of whether the first power supply pin is connected to the third power supply pin 300 or the second power supply pin is connected to the third power supply pin 300. This means the cartridge can be inserted into the device from any direction. The specific circuit structure and principle in the cartridge are described in the example of the information identification control circuit above; repetitions will not be repeated.

[0128] Furthermore, the present invention provides a heating control method for an aerosol supply system, based on the aerosol supply system described above; specifically, as follows: Figure 6 As shown, the method mainly includes the following steps:

[0129] S101. Obtain the resistance value of the identification resistor in the aerosol supply system and obtain the corresponding information;

[0130] S102. Control the heating element according to the information.

[0131] In one implementation, the resistance value of the identification resistor is determined by: charging a capacitor connected in series with the identification resistor and obtaining the charging time and voltage of the capacitor; and then obtaining the resistance value of the identification resistor based on the charging time and voltage. Specifically, the resistance value of the identification resistor can be calculated using the following formula:

[0132] Vt=V0+(V1-V0)×(1-e -t / RC )

[0133] Where V0 is the initial voltage of the capacitor, V1 is the fully charged voltage of the capacitor, Vt is the voltage of the capacitor at time t, C is the capacitance value of the capacitor, and R is the resistance value of the identification resistor.

[0134] According to the above formula, given the capacitance value, the initial voltage of the capacitor, and the full-charge voltage, the resistance value of the identification resistor can be obtained simply by measuring the voltage value at the corresponding moment; or, the resistance value can be obtained by directly obtaining the time it takes for the capacitor to be fully charged. The principle is as follows. Figure 7 The diagram shows the relationship between time and voltage during the capacitor charging process. Since the resistance values ​​of the identification resistors differ, the charging time for the same capacitor also varies. Therefore, a fixed time, such as time T1, can be set to measure the charging voltage at that time. The corresponding resistance value of the identification resistor can be obtained from the charging voltage at that moment. Alternatively, the resistance value can be obtained from the instant of full charging, thus obtaining the information corresponding to the identification resistor. The information corresponding to the identification resistor can be the flavor of the tobacco cartridge, an identification code, or authentication information. Regarding the tobacco cartridge flavor, in this example, the device can calculate the resistance value of the identification resistor to obtain the flavor of the tobacco cartridge. Different flavors require different heating powers. The control circuit outputs the optimal power based on the flavor of the tobacco cartridge to control the heating element, improving the user experience. For example, corresponding to… Figure 7 The detection resistances were measured to be 1.0Ω, 1.2Ω, and 1.4Ω, respectively, and the relationships between these resistances and the flavor profiles of the tobacco cartridges are shown in Table 1 below:

[0135]

[0136]

[0137] Table 1

[0138] In one implementation, such as Figure 8 The process shown allows the capacitor to begin charging to obtain the resistance value of the identification resistor in response to the detection of a user inhaling the aerosol supply system. Specifically, when the user begins inhaling, the measurement and control circuit on the device side is activated, and the capacitor on the cartridge side begins charging. During charging, the voltage of the power supply pin is measured to calculate the corresponding resistance value of the identification resistor. Once the capacitor is fully charged, the control switch is activated, the heating element is connected, and the heating control on the device side is activated to control the heating element to heat according to the heating control output from the device side to generate aerosol. It is important to note that because the device side needs to obtain the resistance value of the identification resistor first and output the heating control scheme based on the information corresponding to the resistance value, the heating element's heating start time needs to be longer than the capacitor's full charging time.
