[0043] Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[0044] Figure 1 This is a schematic diagram of the aerosol generating device provided in the embodiments of this application.
[0045] like Figure 1 As shown, the aerosol generating article 20 is removably received in the aerosol generating apparatus 10. The aerosol generating article 20 includes an aerosol forming matrix, which may include one or more of the following: vanilla leaves, tobacco leaves, homogenized tobacco, expanded tobacco, in powder, granules, fragments, strips, or flakes; or, the aerosol forming matrix may contain additional tobacco or non-tobacco volatile flavor compounds to be released when the matrix is heated. The aerosol generating article 20 may be configured in a shape similar to a conventional cigarette.
[0046] Aerosol generating device 10 includes:
[0047] When the aerosol generating article 20 is received by the aerosol generating apparatus 10, the heating element 101 can heat at least a portion of the aerosol generating article 20 to generate aerosol; this is commonly referred to as circumferential heating or peripheral heating, etc. In this example, the heating element 101 can be configured as a tubular structure, and at least a portion of the aerosol generating article 20 can be inserted into the heating element 101.
[0048] In other examples, it is also possible for the heating element 101 to be inserted into the aerosol-generating article 20 for heating, i.e., central heating or internal heating as commonly referred to. The shape of the heating element 101 includes, but is not limited to, needle-shaped, pin-shaped, or sheet-shaped.
[0049] It should be noted that the heating method of the heating element 101 includes, but is not limited to, resistance heating, electromagnetic heating, infrared heating, air heating, etc.
[0050] Circuit 102 is used to control the aerosol generating device. Circuit 102 includes a control unit, which is a hardware component that controls the overall operation of the aerosol generating device. The control unit can be implemented as an array of logic gates, or it can be implemented as a combination of a microcontroller and a memory, the memory storing a program executable in the microcontroller, such as a control method for the aerosol generating device 10 executable in the microcontroller. Those skilled in the art will understand that the control unit can be implemented in other forms of hardware.
[0051] Power source 103 is used to provide electrical power, such as power to heating element 101, circuit 102, etc. In this example, power source 103 includes a battery cell disposed in aerosol generating device 10, which may be a rechargeable battery cell or a single-use battery cell. In other examples, power source 103 may be a device independent of aerosol generating device 10.
[0052] Based on the above-described aerosol generating device, in one example, the control unit is configured to, upon startup of the heat engine, first control the heating element to rise from an initial temperature to a first preset temperature and maintain it at the first preset temperature for a first preset time; then control the heating element to rise from the first preset temperature to a second preset temperature to end the preheating of the heating element.
[0053] In this example, the second preset temperature is between 240°C and 350°C, or between 240°C and 300°C, or between 240°C and 280°C.
[0054] In this example, the first preset temperature is approximately half of the second preset temperature. In practice, it can be adjusted based on factors such as the suction feel, aerosol temperature, or product temperature. Generally, the first preset temperature can be between 120℃ and 180℃, or between 120℃ and 160℃, or between 120℃ and 150℃, or between 120℃ and 140℃.
[0055] In this example, the first preset time is generally adjusted based on the total preheating time of the heating element, and the first preset time is approximately half of the total preheating time of the heating element. Specifically, the first preset time can be between 5s and 15s, or between 5s and 12s, or between 5s and 10s.
[0056] Thus, by reasonably setting the first preset temperature and the first preset time, the heating element is kept at a low temperature for a period of time before being raised to the target temperature during the start-up of the motor. This avoids problems with the user's inhalation experience, such as the problem of the aerosol generating product 20 absorbing too much energy and causing the aerosol to burn the mouth, or the problem of the aerosol generating product 20 producing too little aerosol at the end of preheating, etc., thereby improving the user experience. It should be noted that in the prior art, sometimes the target temperature during the preheating stage is lowered to avoid the problem of the aerosol burning the mouth, but this will result in a poor inhalation taste (the aerosol is not rich in substances); while the technical solution of this application does not require lowering the target temperature during the preheating stage, and can maintain a better inhalation taste.
[0057] In one example, the control unit is configured to, upon receiving a heating start command, acquire the initial temperature of the heating element; if the initial temperature of the heating element is higher than a preset temperature threshold, initiate a hot start; if the initial temperature of the heating element is lower than the preset temperature threshold, initiate a cold start; wherein, during a cold start, the heating element is controlled to rise from the initial temperature to a third preset temperature.
[0058] In this example, by obtaining the initial temperature of the heating element and comparing it with a preset temperature threshold, it is determined whether to initiate a hot-start or cold-start operation. Generally, the preset temperature threshold is between 40℃ and 90℃, or between 40℃ and 80℃, or between 40℃ and 60℃.
[0059] It is understandable that a hot start is generally caused by continuous use of the aerosol generating device, such as after continuously drawing in multiple aerosol generating products 20. Therefore, in other examples, the decision to enter a hot start phase can also be determined based on the usage interval between two adjacent aerosol generating products 20; specifically, if the usage interval between two adjacent aerosol generating products 20 is less than a preset time threshold, a hot start phase is initiated; otherwise, a cold start phase is initiated.
[0060] In this example, during cold start-up, the heating element is controlled to rise from an initial temperature to a third preset temperature. Generally, the third preset temperature is the same as the second preset temperature. That is, the third preset temperature is between 240℃ and 350℃, or between 240℃ and 300℃, or between 240℃ and 280℃.
[0061] Therefore, specific temperature profiles are used for hot or cold machine startup to avoid problems caused by using the same temperature profile, such as the aforementioned suction experience issues.
[0062] In one example, the control unit is configured to control the heating element to maintain the heating element at the second preset temperature for a second preset time before ending the preheating of the heating element.
[0063] Generally, the second preset time is approximately half of the total preheating time of the heating element. Specifically, the second preset time can be between 5s and 15s, between 5s and 12s, or between 5s and 10s.
[0064] In one example, the control unit is configured to control the power supplied to the heating element to a first preset power, so that the heating element rises from the initial temperature to the first preset temperature; control the power supplied to the heating element to a second preset power lower than the first preset power, so that the heating element maintains the first preset temperature for a first preset time; and control the power supplied to the heating element to a third preset power higher than the second preset power, so that the heating element rises from the first preset temperature to the second preset temperature.
[0065] Generally, the first preset power or the third preset power is the maximum heating power that the power supply can provide to the heating element.
[0066] In one example, the control unit is configured to output a prompt signal indicating that aspirable aerosol has been released when the preheating of the heating element is complete.
[0067] Specifically, a prompting device (not shown in the figure) connected to the control unit can perform a prompting operation based on the prompting signal for aspirable aerosol output by the control unit. For example, the prompting device is a vibration motor, which vibrates to prompt the user that aerosol can be aspirated based on the prompting signal for aspirable aerosol output by the control unit (including a start signal for controlling the operation of the vibration motor); or the prompting device is an LED light, which stays on or flashes to prompt the user that aspirable aerosol can be aspirated based on the prompting signal for aspirable aerosol output by the control unit.
[0068] Figure 2 This is a schematic diagram of the temperature curve for cold start provided in the embodiments of this application.
[0069] like Figure 2As shown, the temperature curve for cold start-up is plotted, with the horizontal axis representing time and the vertical axis representing the temperature of heating element 101. The time period t0–t3 represents the time it takes to draw an aerosol to generate product 20; the time period t0–t2 represents the preheating stage of heating element 101; and the time period t2–t3 represents the drawing stage of heating element 101. T0 represents the initial temperature of heating element 101, Tx represents the preset temperature threshold, T1 represents the third preset temperature of heating element 101, and T2 represents the target temperature maintained by heating element 101 during the drawing stage. Specifically,
[0070] At time t0, when the control unit receives the heating start command, it obtains the initial temperature of the heating element 101 as T0. Since the initial temperature T0 of the heating element 101 is lower than the preset temperature threshold Tx, it enters cold start mode.
[0071] During the time period t0 to t1, when the machine is started from cold, the control unit controls the power supply 103 to provide the heating power to the heating element 101 to the maximum heating power, for example, the maximum power of 36W, so that the temperature of the heating element 101 can be rapidly increased from the initial temperature T0 at time t0 to the third preset temperature T1 at time t1.
[0072] At time t1, when the temperature of the heating element 101 reaches the third preset temperature T1, the control unit controls the heating power supplied by the power supply 103 to the heating element 101 to decrease, and begins to maintain the temperature of the heating element 101 at the third preset temperature T1.
[0073] During the time period t1 to t2, the control unit controls the power supply 103 to provide energy to the heating element 101 in order to maintain the temperature of the heating element 101 at the third preset temperature T1.
[0074] At time t2, when the duration of maintaining the temperature of the heating element 101 at the third preset temperature T1 reaches the duration of the time interval t1 to t2, the control unit outputs a prompt signal indicating that the aerosol can be aspirated, prompting the user to aspirate. At the same time, the control unit further reduces the heating power supplied to the heating element 101 by the power supply 103 and begins to maintain the temperature of the heating element 101 at the target temperature T2.
[0075] During the time period t2 to t3, the control unit controls the power supply 103 to provide energy to the heating element 101 in order to maintain the temperature of the heating element 101 at the target temperature T2 until the suction ends, i.e., at time t3.
[0076] In practical operation, the control unit can obtain the real-time temperature of the heating element 101 through a temperature sensing element, which includes, but is not limited to, thermocouples and temperature sensing components with a temperature coefficient of resistance. In some examples, if the heating element 101 is made of a material with a temperature coefficient of resistance, the heating element 101 can also serve as a temperature sensing element.
[0077] Figure 3 This is a schematic diagram of the temperature curve for starting up a heat engine, provided in an embodiment of this application.
[0078] like Figure 3 As shown, the temperature curve for heat engine start-up is plotted, with the horizontal axis representing time and the vertical axis representing the temperature of heating element 101. The time period from t0 to t3 represents the time period for drawing an aerosol to generate product 20; the time period from t0 to t2' represents the preheating stage of heating element 101; and the time period from t2' to t3 represents the drawing stage of heating element 101. T0 represents the initial temperature of heating element 101, Tx represents the preset temperature threshold, T10 represents the first preset temperature of heating element 101, T1' represents the second preset temperature of heating element 101, and T2 represents the target temperature maintained by heating element 101 during the drawing stage. Specifically,
[0079] At time t0, when the control unit receives the heating start command, it obtains the initial temperature T0 of the heating element 101. Since the initial temperature T0 of the heating element 101 is higher than the preset temperature threshold Tx, the system initiates a hot start.
[0080] During the time period from t0 to t11, when the engine starts up, the control unit controls the power supply 103 to provide the heating power to the heating element 101 at the maximum heating power, for example, a maximum power of 36W, so that the temperature of the heating element 101 can be rapidly increased from the initial temperature T0 at time t0 to the first preset temperature T10 at time t11.
[0081] At time t11, when the temperature of the heating element 101 reaches the first preset temperature T10, the control unit controls the power supply 103 to reduce the heating power supplied to the heating element 101 and begins to maintain the temperature of the heating element 101 at the first preset temperature T10.
[0082] During the time period t11 to t12, the control unit controls the power supply 103 to provide energy to the heating element 101 in order to maintain the temperature of the heating element 101 at the first preset temperature T10.
[0083] At time t12, when the duration of maintaining the temperature of the heating element 101 at the first preset temperature T10 reaches the duration of the time interval t11 to t12, the control unit controls the power supply 103 to increase the heating power supplied to the heating element 101, and raises the temperature of the heating element 101 again.
[0084] During the time period t12 to t13, the control unit controls the power supply 103 to supply the heating power to the heating element 101 to the maximum heating power, for example, the maximum power of 36W, so that the temperature of the heating element 101 can be rapidly increased from the first preset temperature T10 at time t12 to the second preset temperature T1' at time t13.
[0085] At time t13, when the temperature of the heating element 101 reaches the second preset temperature T1', the control unit controls the power supply 103 to reduce the heating power supplied to the heating element 101 and begins to maintain the temperature of the heating element 101 at the second preset temperature T1'.
[0086] During the time period t13~t2', the control unit controls the power supply 103 to provide energy to the heating element 101 in order to maintain the temperature of the heating element 101 at the second preset temperature T1'.
[0087] At time t2', when the duration of maintaining the temperature of heating element 101 at the second preset temperature T1' reaches the duration of the time interval t13 to t2', the control unit outputs a prompt signal indicating that the aerosol can be aspirated, prompting the user to aspirate. At the same time, the control unit further reduces the heating power supplied to heating element 101 by power supply 103 and begins to maintain the temperature of heating element 101 at the target temperature T2.
[0088] During the time period t2' to t3, the control unit controls the power supply 103 to provide energy to the heating element 101 in order to maintain the temperature of the heating element 101 at the target temperature T2 until the suction ends, i.e., at time t3.
[0089] Similarly, in actual operation, the control unit can obtain the real-time temperature of the heating element 101 through a temperature sensing element, which includes, but is not limited to, thermocouples and temperature sensing components with a temperature coefficient of resistance. In some examples, if the heating element 101 is made of a material with a temperature coefficient of resistance, the heating element 101 can also serve as a temperature sensing element.
