Description

Technical Field

[0001] This invention relates to the field of heated smoke appliances, and in particular to a power protection control method for the start-up phase of a heated smoke appliance, a heated smoke appliance, and a storage medium. Background Technology

[0002] With increasingly stringent regulations on cigarettes in various countries and growing public awareness of health, heated tobacco products (HTPs) have become increasingly popular in recent years. These products primarily work by vaporizing substances like nicotine from tobacco, allowing users to inhale the vapor.

[0003] Currently, the most common type of heated tobacco product is the resistance heating type. Resistance heating devices can be further divided into two main categories based on the relative positions of the heater and the tobacco medium: internal heating and external heating.

[0004] Among them, externally heated smoking appliances have the advantage of high efficiency in utilizing the smoke medium, but also have significant disadvantages: slow heating speed and low heat transfer efficiency. To improve the heating speed, resistance-heated smoking appliances often use a method of reducing the heater resistance for temperature control. However, this also increases the requirements for battery power and temperature control schemes. For example, during the heating process, the power supply needs to output a large current instantaneously to heat the aerosol, which leads to higher requirements for the battery's output capacity. This also causes a series of problems such as severe overheating of the electronic switch controlling the heater power, increased circuit loss, reduced battery cycle life, and reduced appliance endurance. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a power protection control method for the start-up phase of a heated smoke appliance, which reduces the instantaneous current required when starting a non-combustible smoke appliance, thereby protecting the power supply and solving the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] In a first aspect, one embodiment of this application provides a power protection control method for the start-up phase of a heated smoking appliance. The heated smoking appliance includes a heating chamber, a power supply, a heater, and a controller. The heater is used to heat an aerosol-forming matrix contained in the heating chamber during operation to generate aerosols. The heater includes a heating resistor group. Under the control of the controller, the power supply and the heating resistor group can respectively form a first heating circuit with a first resistance and a second heating circuit with a second resistance, wherein the first resistance is greater than the second resistance. The first heating circuit and the second heating circuit are used to transmit power energy to generate heat in the same area of ​​the heater. The controller can monitor the operating parameters of the first heating circuit and the second heating circuit. The power protection control method for the start-up phase includes the following steps: Step 1: The controller starts the first heating circuit; Step 2: The controller controls the first heating circuit to work to transmit power energy to the heater, and the controller simultaneously acquires the operating parameters of the heated smoking appliance; Step 3: The controller determines whether the operating parameters of the heated smoking appliance exceed a preset parameter threshold: if yes, the controller switches the first heating circuit to the second; if no, the above step 2 is repeated.

[0008] Furthermore, the operating parameters of the heating appliance are parameters related to any combination of the following: the heating power of the first heating circuit, the temperature of the heater, the continuous working time after startup, the current flowing through at least a portion of the heating resistor group, the voltage of at least a portion of the heating resistor group, and the resistance of at least a portion of the heating resistor group.

[0009] Furthermore, the heating resistor group includes a common resistor, and both the first heating circuit and the second heating circuit include a common resistor.

[0010] Furthermore, the heating resistor group includes a first resistor and a second resistor. The controller controls the power supply and selects the common resistor to form a first heating circuit with the first resistor or to form a second heating circuit with the second resistor.

[0011] Furthermore, the resistance of the second resistor increases as the heater temperature rises, and the controller determines whether the resistance of the second resistor is safe for the power supply based on whether the operating parameters of the heating appliance exceed the preset parameter threshold.

[0012] Furthermore, the heating resistor group includes a first resistor and a second resistor, and the controller controls the power supply to select the first and second resistors connected in series to form a first heating circuit or to select the first and second resistors connected in parallel to form a second heating circuit.

[0013] Furthermore, the control method also includes: Step 4: After switching to the second heating circuit, the controller continues to acquire the operating parameters of the heating appliance; the controller determines whether the operating parameters of the heater exceed the preset parameter threshold: if yes, the controller disconnects the second heating circuit and stops transmitting power energy to the heater; if no, the second heating circuit continues to operate.

[0014] Secondly, this application also provides a heated smoking device, which includes: a heating chamber, a power supply, a heater, and a controller. The heater is used to heat an aerosol-forming matrix contained in the heating chamber during operation to generate aerosol. The heater includes a heating resistor group. Under the control of the controller, the power supply and the heating resistor group can respectively form a first heating circuit with a first resistance and a second heating circuit with a second resistance, wherein the first resistance is greater than the second resistance. The first heating circuit and the second heating circuit are used to transmit power energy to generate heat in the same area of ​​the heater. The controller can monitor the operating parameters of the first heating circuit and the second heating circuit. The controller is configured to: start the first heating circuit; control the first heating circuit to operate to transmit power energy to the heater; simultaneously acquire the operating parameters of the heated smoking device; determine whether the operating parameters of the first heating circuit exceed a preset parameter threshold; if yes, switch the first heating circuit to the second heating circuit to operate to transmit power energy to the heater; if no, control the first heating circuit to transmit power energy to the heater.

[0015] Furthermore, the controller includes a memory and a processor. The memory stores computer-readable instructions, which, when executed by the processor, cause the processor to perform a power protection control method for the start-up phase of a heated smoke appliance as provided in the first aspect above.

[0016] Thirdly, this application provides a non-volatile readable storage medium storing computer-readable instructions, which, when executed by a processor, cause the processor to perform the function of a heated smoke appliance as described in the first aspect embodiment or in combination with the second aspect embodiment.

[0017] The aerosol-generating article is a smoking article, comprising an aerosol-forming matrix that generates an aerosol through heating, which can be directly inhaled into the lungs of a user. Preferably, the aerosol-forming matrix is ​​a solid aerosol-forming matrix. The aerosol-forming matrix may simultaneously comprise solid and liquid components. Preferably, the aerosol-forming matrix includes nicotine. In some preferred embodiments, the aerosol-forming matrix includes tobacco.

[0018] An aerosol generating device is used to describe an apparatus that interacts with an aerosol-forming matrix of an aerosol-generating article to generate an aerosol. Preferably, the aerosol generating device is a heated smoking device that interacts with the aerosol-generating matrix of the aerosol-generating article to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. The aerosol generating device can also be a holder for a smoking article.

[0019] The power source can be any suitable power source, such as a DC voltage source, like a battery. In one embodiment, the power source is a lithium-ion battery. Alternatively, the power source can be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or lithium polymer battery.

[0020] The control element can be a simple switch. Alternatively, the control element can be a circuit and may include one or more microprocessors or microcontrollers.

[0021] An aerosol generation system may include an aerosol generation device and one or more aerosol generation articles, wherein the aerosol generation device is configured with a corresponding number of heating chambers to contain the aerosol generation articles.

[0022] As can be seen from the above technical solution, the advantages and positive effects of the power protection control method for the start-up phase of the heated smoke appliance proposed in this invention are as follows:

[0023] Under the control of the controller, the power supply and heating resistor group form a first heating circuit and a second heating circuit. During the power-on phase, the controller first starts the first heating circuit with a higher resistance value to prevent high current from damaging the battery power supply. Then, by acquiring the operating parameters of the heating appliance, the controller determines to switch to the second heating circuit with a lower resistance value. This ensures that the resistance value of the heater is always at a relatively high value, improving the overall load capacity of the heating circuit and ensuring that the battery output current is always suppressed to a relatively low level, thereby improving the protection of the battery power supply.

[0031] The following detailed description of the features and advantages of the present invention is sufficient to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly. Furthermore, based on the specification, claims and drawings disclosed herein, those skilled in the art can easily understand the related objects and advantages of the present invention.

[0032] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0035] In a first embodiment of the present invention, the heated smoke appliance may include: a heating chamber, a power supply, a heater, and a controller. The heater is used to heat an aerosol-forming matrix housed within the heating chamber during operation to generate an aerosol. The heater may include a heating resistor array. Under the control of the controller, the power supply and the heating resistor array can respectively form a first heating circuit with a first resistance and a second heating circuit with a second resistance, wherein the first resistance is greater than the second resistance. The controller can monitor the operating parameters of the first and second heating circuits.

[0036] It should be noted that the first heating circuit and the second heating circuit are used to transmit power to generate heat in the same area of ​​the heater, and not to heat different areas of the cigarette.

[0037] The controller can be an MCU (Micro Controller Unit).

[0038] Please refer to Figure 1 As shown, the control method for power protection during the start-up phase of the heating fume appliance via the controller may include the following steps:

[0039] S1: Start the first heating circuit.

[0040] S2: Control the first heating circuit to transmit power to the heater, and at the same time acquire the operating parameters of the heating fume.

[0041] In one embodiment, the controller can periodically acquire the operating parameters of the heating appliance at longer time intervals in order to reduce power consumption.

[0042] S3: Determine whether the operating parameters of the heating appliance exceed the preset parameter threshold: If yes, switch the first heating circuit to the second heating circuit to transmit power energy to the heater; if no, continue to repeat step two above.

[0043] Under the control of the controller, the power supply and heating resistor group form a first heating circuit and a second heating circuit. During the power-on phase, the controller first activates the first heating circuit with a higher resistance value to prevent high current from damaging the battery power supply. Then, by acquiring the operating parameters of the heating appliance, the controller determines to switch to the second heating circuit with a lower resistance value. This ensures that the resistance value of the heater is always at a relatively high value, improving the overall load capacity of the heating circuit and ensuring that the battery output current is always suppressed to a relatively low level, thereby improving the protection of the battery power supply.

[0044] The operating parameters of the heating appliance can be parameters related to any one or more of the following: the heating power of the first heating circuit, the temperature of the heater, the continuous working time after startup, the current flowing through at least a portion of the heating resistor group, the voltage of at least a portion of the heating resistor group, and the resistance of at least a portion of the heating resistor group.

[0045] In one embodiment, the heating resistor group may include a common resistor, and both the first heating circuit and the second heating circuit include the common resistor.

[0046] The heating resistor group includes a first resistor and a second resistor. The controller controls the power supply and selects the common resistor to form a first heating circuit with the first resistor or to form a second heating circuit with the second resistor.

[0047] Please refer to Figure 2 Under the control of the controller, the common resistor and the first resistor form a high-resistance first heating circuit, and the common resistor and the second resistor form a low-resistance second heating circuit. The first heating circuit and the second heating circuit form two heating tracks in the heater. Among them, 1-2 is the heating track of the higher-resistance first heating circuit, and 3-2 is the heating track of the lower-resistance second heating circuit.

[0048] When the heating appliance is started, the controller first starts the first heating circuit and shuts down heating track 3-2. During the process of the first heating circuit supplying energy to the heater, the heater's heating track is 1-2. When the controller obtains that the current temperature of the heater is greater than the preset threshold, the controller shuts down heating track 1-2 and switches to heating track 3-2 for heating.

[0049] Specifically, you can refer to Figure 3 The controller starts heating trajectory 1-2 to power the heater. During this process, the controller captures the real-time temperature of heating trajectory 1-2 and determines whether the real-time temperature of heating trajectory 1-2 has reached the threshold temperature 1. If not, the controller continues to start heating trajectory 1-2 to power the heater until the controller determines that the real-time temperature of heating trajectory 1-2 has reached 1.

[0050] When the real-time temperature of heating trajectory 1-2 reaches 1, the controller shuts down heating trajectory 1-2 and starts heating trajectory 3-2 to power the heater. Then, during the heating process of heating trajectory 3-2, the controller captures the real-time temperature of heating trajectory 3-2 and determines whether the real-time temperature of heating trajectory 3-2 has reached the threshold temperature 2. If not, the controller continues to start heating trajectory 3-2 to power the heater until it determines that the real-time temperature of heating trajectory 3-2 has reached 2.

[0051] When the controller determines that the real-time temperature of the 3-2 heating trajectory has reached the preset temperature 2, the controller controls the 3-2 heating trajectory to shut down.

[0052] It can be understood that threshold temperature 2 can be the target temperature for heating. For example, if the target temperature for heating the smoke device is 200℃, then threshold temperature 2 is 200℃. Threshold temperature 1 is the transition temperature, which is lower than threshold temperature 2. Threshold temperature 1 can be set to 100℃. The purpose of threshold temperature 1 is to make the first heating circuit corresponding to heating trajectory 1-2 heat up first, increase the temperature of the heater, thereby increasing the resistance of the second heating circuit corresponding to heating trajectory 3-2, which has a lower resistance than at room temperature. This avoids excessive instantaneous current output from the battery power supply when switching to heating trajectory 3-2, which would affect the battery life.

[0053] It is understandable that this allows the resistance of the heating trajectory formed by the first and second heating circuits to remain at a relatively high value, thus suppressing the current output by the battery power supply to a relatively low level and improving the protection of the battery power supply.

[0054] Further, please refer to Figure 4R1 is the room temperature resistance of the first heating circuit, and R0 is the room temperature resistance of the second heating circuit, where R1 > R0. According to Ohm's law, when the same voltage is applied to the first heating circuit, the current flowing through it is less than the current flowing through the second heating circuit. That is, by activating the higher-resistance first heating circuit during the start-up phase of the heating appliance, the controller can effectively reduce the battery's output current during heating startup. When the controller detects that the heater has reached the threshold temperature, it switches the first heating circuit to the lower-resistance second heating circuit to continue supplying power to the heater. At this point, since the heater already has a certain temperature, the second heating circuit heats up, and its resistance is greater than R0. Therefore, the controller can control the battery to output less current.

[0055] It is understandable that, since the resistance of a low-resistance heating circuit is lower than that of a high-resistance heating circuit at the same temperature, switching the first heating circuit to the second heating circuit for power supply can keep the electrical power on the heater at a higher level, thereby improving the heating efficiency of the smoking appliance.

[0056] The resistance of the second resistor increases as the heater temperature rises. The controller can determine whether the resistance of the second resistor is safe for the power supply based on whether the operating parameters of the heating appliance exceed the preset parameter threshold.

[0057] For example, the controller can acquire the temperature of the heater and determine whether the resistance of the second resistor is safe for the power supply by checking whether the temperature of the heater exceeds a preset parameter threshold.

[0058] The controller can also determine whether the resistance of the second resistor is safe for the power supply by acquiring the continuous working time after startup, the current flowing through at least a part of the heating resistor group, the voltage of at least a part of the heating resistor group, the resistance of at least a part of the heating resistor group, and any combination of the above parameters.

[0059] It is understandable that the controller determines whether the resistance of the second resistor is safe for the power supply based on the operating parameters of the heating appliance. The specific process is well known to those skilled in the art and will not be elaborated further here.

[0060] Please refer to Figure 2 and Figure 5 , Figure 5 This is a block diagram of an electrical control system provided in one embodiment of this application. The controller can also be connected to and interact with devices and functional modules such as charging management, discharge protection, power detection, battery temperature detection, buttons, and LED indicators. The controller is connected to a control circuit corresponding to the heating appliance control method provided in the above embodiment to supply power to the heater, thereby enabling the heater to heat the appliance.

[0061] For example, please refer to Figure 6 During the operation of the heating appliance, the controller can first control the switching switch to connect node 1 via a control signal, so that the current from the battery power supply flows through node 1 to the heater, and then flows back to the battery from node 2 through the protection circuit, forming the first heating circuit. The controller then controls the switching switch to connect node 3 via a control signal, so that the current from the battery power supply flows through node 3 to the heater, and then flows back to the battery from node 2 through the protection circuit, forming the second heating circuit.

[0062] It is understandable that the first and second heating circuits are connected in series with the protection circuit, so that during the discharge process of the battery power supply, the current passes through the protection circuit, thereby improving the protection of the battery power supply and related components.

[0063] In another embodiment, the heating resistor group may include a first resistor and a second resistor, and the controller controls the power supply to select the first resistor and the second resistor connected in series to form a first heating circuit or to select the first resistor and the second resistor connected in parallel to form a second heating circuit.

[0064] Furthermore, the control method may also include: Step 4: After switching to the second heating circuit, the controller continues to acquire the operating parameters of the heating appliance; the controller determines whether the operating parameters of the heater exceed the preset parameter threshold: if yes, the controller disconnects the second heating circuit and stops transmitting power energy to the heater; if no, the second heating circuit continues to operate.

[0065] It is understandable that after the controller switches to start the main power control loop to continue supplying power to the heater, the controller can obtain the operating parameters of the heating appliance, such as the temperature of the heater, through the temperature acquisition circuit and other means. This allows the controller to manage the input and output power of the battery power supply based on the temperature curve of the heater.

[0066] It should be noted that the specific setup and implementation process of the temperature acquisition circuit are well known to those skilled in the art, and will not be described in detail here.

Under the control of the controller, the power supply and the heating resistor group can respectively form a first heating circuit with a first resistance and a second heating circuit with a second resistance. The first resistance is greater than the second resistance. The first heating circuit and the second heating circuit are used to transmit power energy to generate heat in the same area of ​​the heater. The controller can monitor the operating parameters of the first heating circuit and the second heating circuit.

[0069] The controller can be configured to: start the first heating circuit; control the first heating circuit to operate to transmit power energy to the heater; simultaneously acquire the operating parameters of the heating appliance; determine whether the operating parameters of the first heating circuit exceed a preset parameter threshold: if yes, switch the first heating circuit to the second heating circuit to operate to transmit power energy to the heater; if no, control the first heating circuit to transmit power energy to the heater.

[0070] In one embodiment, the controller may include a memory and at least one processor configured to execute the applicable method steps according to the invention. Furthermore, the method according to the invention can be implemented using one or more computer programs, which can be executed by at least one processor or controller.

[0071] In one embodiment, the method steps, apparatus, and computer program according to the invention can be implemented by at least one separate or embedded hardware module.

[0072] Computer programs can be stored on at least one computer-readable medium, such as memory circuitry, a memory card, a disk, or an optical disk. Some functional entities can be implemented by program modules linked to another functional entity. Functional entities can also be stored in separate memory and executed by a separate processor that can communicate via, for example, a message bus. An example of such a message bus could be a Peripheral Component Interconnect (PCI) bus.
