Description

Technical Field

[0001] This application relates to the field of atomization technology, and more particularly to a control method and an electronic atomization device. Background Technology

[0002] HNB (Heat Not Burn) e-cigarette products generate aerosols by heating an aerosol-generating matrix with a heating element. The aerosol-generating matrix is ​​the heated element. In related technologies, changes in the airflow inside the e-cigarette device are detected to determine if the user is inhaling. For example, when the user inhales, the controller detects a change in air pressure and activates the heating element.

[0003] Because this solution only heats the electronic atomizer when the user starts inhaling, the temperature of the atomizing chamber in the electronic atomizer has not reached its optimal state when the user takes the first puff. As a result, the amount of aerosol produced is small and accompanied by a cold breath. This is more noticeable when used in low-temperature conditions such as winter, which seriously affects the user's inhalation taste and user experience. Summary of the Invention

[0004] This application provides a control method and an electronic atomizing device, which can solve the problem that when a user takes their first puff, the temperature of the atomizing chamber in the electronic atomizing device does not reach a better state, resulting in a poor user experience.

[0006] When the electronic atomizing device is detected to have a tendency to be drawn in, the heating module is controlled to heat the heated body.

[0007] In one possible implementation of the first aspect, the housing of the electronic atomizing device is provided with a sensor, and before controlling the heating module to heat the heated body when the electronic atomizing device is detected to have a tendency to be drawn in, the method includes:

[0008] The sensor determines whether the electronic atomizing device has a tendency to be drawn in based on the signal detected by the sensor.

[0009] In one possible implementation of the first aspect, before controlling the heating module to heat the heated body when the state of detecting that the electronic atomizing device has a tendency to be drawn in is mentioned, the method includes:

[0010] Based on one or more sensors in a preset sensor combination, it is determined whether the electronic atomizing device has a tendency to be drawn in; the preset sensor combination includes: a multi-axis accelerometer, a multi-axis gyroscope, an image sensor, an infrared temperature sensor, and a distance sensor.

[0011] In one possible implementation of the first aspect, the electronic atomizing device includes an atomizing chamber for accommodating the heated body to be heated; the heating module includes a heating element for heating the heated body.

[0012] The step of controlling the heating module to heat the heated body when the electronic atomizing device is detected to have a tendency to be drawn in includes:

[0013] When the electronic atomizing device is detected to have a suction tendency, the real-time temperature of a preset detection object is obtained; the preset detection object includes at least one of the heated body, the atomizing chamber, and the heating element.

[0014] If the real-time temperature of a preset detection object is lower than a preset temperature threshold, the heating module is controlled to heat the object.

[0015] In one possible implementation of the first aspect, controlling the heating module to heat the heated body includes:

[0016] Based on a preset mapping relationship, heating parameter values ​​that match the real-time temperature of the preset detection object are determined; the preset mapping relationship records heating parameter values ​​corresponding to different real-time temperatures.

[0017] The heating module is controlled to heat the heated body according to the heating parameter values.

[0018] In one possible implementation of the first aspect, the real-time temperature in the preset mapping relationship is negatively correlated with the heating parameter value.

[0019] In one possible implementation of the first aspect, the method includes:

[0020] When the activation of the electronic atomizing device is detected, it is determined that the electronic atomizing device has a tendency to be inhaled.

[0021] In one possible implementation of the first aspect, controlling the heating module to heat the heated body includes:

[0022] The heating module is controlled to heat the heated body sequentially with a first heating parameter value and a second heating parameter value;

[0023] Wherein, when heated based on the first heating parameter value, the temperature rise of the heated body per unit time is greater than that when heated based on the second heating parameter value.

However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details.

Similarly, the phrase "if determined" or "if detected [the described condition or event]" may be interpreted, depending on the context, as meaning "once determined," "in response to determination," "once detected [the described condition or event]," or "in response to detection [the described condition or event]."

[0043] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0045] One embodiment of this application discloses a control method applied to an electronic atomizing device. The electronic atomizing device includes a heating module, a passive component, and an active component. The passive component stores and transports unheated heat-receiving material, while the active component houses the heated heat-receiving material and drives the passive component to rotate via the heated material. The heating module heats the heat-receiving material to generate an aerosol. The heating module can be a contact or non-contact heating method, and the heating method includes, but is not limited to, resistance heating, electromagnetic heating, laser heating, microwave heating, and infrared radiation heating; this application does not impose any limitations on this. Exemplarily, the active component can be an active wheel, and the passive component can be a passive wheel.

[0046] In this embodiment, the heated body is a thin, flexible medium. The heated body may consist only of an aerosol generating matrix, or it may include both an aerosol generating matrix and a baseband. The baseband is located between the aerosol generating matrix and the heating element in the heating module, and the baseband can contact the heating element in the heating module. Optionally, the thickness of the heated body is 0.05mm-0.5mm.

[0047] The aerosol generating matrix is ​​used to generate aerosols by being heated by a heating element. Exemplarily, the aerosol generating matrix can be used to generate aerosols in a non-combustible manner. That is, the aerosol generating matrix is ​​heated below its ignition point to generate aerosols. The aerosol generating matrix does not burn during the aerosol generation process. An electronic atomizing device is used to allow a user to inhale the aerosol generated by the aerosol generating matrix.

[0048] like Figure 1 As shown, the control method provided in this embodiment includes the following steps:

[0049] S110, when the electronic atomizing device is detected to have a tendency to be drawn in, the heating module is controlled to heat the heated body.

[0050] This allows for preheating of the heating element before the user inhales, increasing its temperature to ensure better atomization during the user's first puff. This results in a sufficient aerosol volume and suitable aerosol temperature generated in the electronic atomization device to meet user needs and achieve a superior taste experience. Furthermore, in this embodiment, the amount of aerosol released during preheating needs to be sufficiently small (e.g., less than 2.5mg) to guarantee a good user experience.

[0051] Regarding the method for determining the inhalation tendency, the control module can determine it based on one or more sensors from a preset sensor combination. Alternatively, it can estimate the motion trend of the electronic atomizing device by measuring changes in acceleration, tilt angle, and rotation angle in multiple directions, thereby determining whether the user is preparing to inhale, i.e., has an inhalation tendency. It can also determine whether there is an inhalation tendency by detecting whether the electronic atomizing device is activated; for example, if the electronic atomizing device is activated, such as when a physical switch button is turned on, it is determined that there is an inhalation tendency. Otherwise, it is determined that there is no inhalation tendency. In some optional embodiments, the inhalation tendency can also be detected by detecting the grip posture of the electronic atomizing device and changes in the capacitance values ​​of some preset grip points using a gravity sensor; this will not be elaborated further in this application. Multiple preset grip points can be set, which can improve the accuracy of the judgment.

[0052] The aforementioned preset sensor combination includes: a gravity sensor, a multi-axis accelerometer, a multi-axis gyroscope, an image sensor, an infrared temperature sensor, and a distance sensor. For example, it can determine whether a face is close to the electronic atomizing device by using an image or sensor, thereby achieving detection; or it can determine this by combining a multi-axis accelerometer with a multi-axis gyroscope. This application does not impose any limitations on this.

[0053] Another embodiment of this application discloses another control method. For example... Figure 2 As shown, this embodiment is based on the above. Figure 1Based on the corresponding embodiment, the housing of the electronic atomizing device is equipped with a sensor. Before step S110, the following step is also included:

[0054] S100, determine whether the electronic atomizing device has a tendency to be drawn in based on the signal detected by the above sensor.

[0055] In this embodiment, when the sensor located on the device casing detects a corresponding signal, the operating state of the electronic atomizing device can be switched from a sleep state to an awake state. If the sensor does not detect a corresponding signal, the operating state of the electronic atomizing device can remain unchanged, such as remaining in a sleep state. The energy consumed per unit time in the sleep state is less than that consumed per unit time in the awake state. In one possible implementation, the sensor can be a touch sensor. Specifically, transparent conductive material can be covered on the two surfaces or other locations of the electronic atomizing device, such as the casing. When a user's hand touches or holds the device, a capacitor is formed based on the capacitance of the human body. By detecting changes in the capacitance, it can be determined whether a touch signal has been detected. When only a single point of electrical charge changes around the device casing, the electronic atomizing device cannot be awakened, avoiding accidental triggering of heating and reducing power consumption. In other embodiments, the sensor can also be a gravity sensor or other types of sensors, or a combination of multiple types of sensors; this application does not limit this.

[0056] This embodiment utilizes the conductivity of the human body to determine whether to wake up the electronic atomizing device based on the user's hand gesture. This allows the electronic atomizing device to remain in a low-power sleep state when not in use, and to be woken up in advance when the user shows signs of inhalation, thereby reducing the standby power consumption of the electronic atomizing device.

[0057] In some optional embodiments, when the e-cigarette device remains in the wake-up state for a first preset duration and no vaping trend is detected, the e-cigarette device is switched back to sleep mode, thereby reducing the standby power consumption of the e-cigarette device. For example, the first preset duration may be 5 seconds.

[0058] In some optional embodiments, the electronic atomizing device is equipped with an infrared sensing unit. When the electronic atomizing device is in a wake-up state, if the user's hand is detected touching the infrared sensing unit, preheating and heating are prohibited, and a shielding anti-touch mode is activated to prevent accidental triggering of the electronic atomizing device to heat up and reduce power consumption.

[0059] In other embodiments, the sensor described above for detecting touch signals can be replaced with one or more of the following: conductive materials, capacitive sensors, infrared sensors, gravity sensors, multi-axis accelerometers, pressure sensors, multi-axis gyroscopes, image sensors, and distance sensors. For example, a touch signal can be determined by detecting the heat of a human body or capturing a thermal image of a face using an infrared sensor, or by determining that a touch signal has been detected when the infrared sensor detects that the electronic atomizing device is close to the user's mouth.

[0060] For the method of determining the suction trend, please refer to the description above. If there is a suction trend, proceed to step S110. Otherwise, proceed to step S100.

[0061] In some alternative embodiments, in the above Figure 1 Based on the corresponding embodiment, the electronic atomizing device includes an atomizing chamber for accommodating the object to be heated. The heating module includes a heating element for heating the object. Figure 3 As shown, step S110 includes:

[0062] S1101, when a suction tendency is detected in the electronic atomizing device, the real-time temperature of a preset detection object is acquired. The preset detection object includes at least one of a heated body, an atomizing chamber, and a heating element.

[0063] S1102: If the real-time temperature of a preset detection object is lower than a preset temperature threshold, the heating module is controlled to heat the object. Otherwise, no heating is performed.

[0064] In step S1102, if the temperature of the heated object can be obtained, it is first determined whether the temperature of the heated object is less than a preset temperature threshold. If it is less, the heating module is controlled to heat the heated object. Otherwise, no heating is performed. If the temperature of the heated object cannot be obtained, the real-time temperature of at least one of the atomizing chamber and the heating element is obtained and compared with the preset temperature threshold. In other embodiments, it can also be set so that the heating module is controlled to heat the heated object only when the temperatures of multiple or all preset detection objects are less than the preset temperature threshold.

[0065] This embodiment determines whether heating is necessary by detecting the real-time temperature of a preset detection object. This helps reduce the power consumption of the electronic atomization device and prevents the heated object from being overheated and baked, which could produce harmful substances or result in a poor inhalation experience, thus ensuring a better taste experience for the user.

[0066] In some alternative embodiments, in the above Figure 3 Based on the corresponding embodiments, such as Figure 4 As shown, step S1102 includes:

[0067] S11021, if the real-time temperature of a preset detection object is lower than a preset temperature threshold, then according to a preset mapping relationship, a heating parameter value matching the real-time temperature of the preset detection object is determined. The preset mapping relationship records the heating parameter values ​​corresponding to different real-time temperatures.

[0068] S11022, the heating module controls the heating of the heated body according to the heating parameter values.

[0069] In this embodiment, the real-time temperature and heating parameter values ​​are negatively correlated in the preset mapping relationship. That is, the heating parameter values ​​increase as the real-time temperature decreases, and decrease as the real-time temperature increases. For example, the heating parameter values ​​can be the average heating power.

[0070] This embodiment determines appropriate heating parameter values ​​based on the real-time temperature of the preset detection object. On the one hand, this helps to reduce the power consumption of the electronic atomization device, and on the other hand, it can prevent the heated object from being overheated and baked, producing harmful substances or producing a poor inhalation taste, thus ensuring that users have a better taste experience.

[0071] In one embodiment, step S110 is replaced by:

[0072] When the electronic atomizing device is detected to have a tendency to be drawn in, the heating module is controlled to heat the heated body sequentially with the first heating parameter value and the second heating parameter value.

[0073] Specifically, when heating based on the first heating parameter value, the temperature rise of the heated object per unit time is greater than that when heating based on the second heating parameter value. That is, the temperature rise rate is faster when heating based on the first heating parameter value, which is beneficial for meeting some temporary suction needs and ensuring timely and rapid preheating of the heated object. Optionally, the temperature rise rate when heating based on the first heating parameter value is greater than a preset temperature rise threshold. Alternatively, the first heating parameter value is greater than a first preset power threshold. This ensures rapid temperature rise during the initial preheating stage, meeting the user's immediate suction needs.

[0074] In one possible implementation, the first heating parameter value and the second heating parameter value are respectively the average heating power within their respective time periods, that is, the average value of the heating power within the corresponding time periods. The first heating parameter value is greater than the second heating parameter value, and the heating duration corresponding to the first heating parameter value is less than the heating duration corresponding to the second heating parameter value.

[0075] Specifically, in this embodiment, the heating process of the heated object includes two stages: a preheating stage and a main heating stage. The preheating stage is triggered by detecting a tendency for the electronic atomizing device to be drawn in. The main heating stage is triggered by detecting a drawn-in action on the electronic atomizing device, which can be determined by changes in the air pressure at the inlet of the electronic atomizing device. For example, when a negative pressure (i.e., pressure lower than ambient atmospheric pressure) forms at the inlet, a drawn-in action is triggered.

[0076] During the preheating stage, the electronic atomizing device controls the heating module to heat the object. This preheating stage can be based on a short period of high-power operation, or a longer period of low-power operation. Alternatively, both can be combined, i.e., high-power operation for a short period followed by low-power operation for a longer period. "High power" and "low power" refer to the average power over the corresponding time period. In one possible implementation, the high power is greater than a first preset power, and the low power is less than the first preset power. "Short time" refers to a duration less than the first preset duration, and "longer time" refers to a duration greater than the first preset duration. For example, the first preset power can be 8W, and the first preset duration can be 1 second.

[0077] refer to Figure 5 It shows the curve of the surface temperature of the heated body changing over time when heating is performed using a combination of high and low power during the preheating stage. Figure 5 In the process, preheating stage C includes high-power preheating stage A and heat preservation stage B. High-power preheating stage A involves controlling the heating module to heat the object at high power for a short period, for example, an average power of 10W. Heat preservation stage B involves controlling the heating module to heat the object at lower power for a longer period, for example, an average power of 7W, keeping the object temperature at a lower level, such as below 180℃. This prevents the object temperature from dropping too low before the user inhales, ensuring the object temperature remains within a stable and suitable range before inhalation, guaranteeing a better first inhalation experience for the user.

[0078] In some optional embodiments, during the heat preservation stage B, the heating module can be turned on and off periodically or non-periodically to heat the object being heated. That is, the object being heated is heated intermittently. This balances energy consumption and heat preservation.

[0079] In some optional embodiments, if the preheating stage lasts for a second preset duration and no user-triggered inhalation is detected, the electronic atomizing device is switched back to sleep mode, thereby reducing the standby power consumption of the electronic atomizing device. For example, the second preset duration may be 10 seconds.

[0080] In some alternative embodiments, step S110 can also be replaced by:

[0081] When the electronic atomizing device is detected to have a tendency to be drawn in, the heating module is controlled to heat the heated body with either the first heating parameter value or the second heating parameter value mentioned above.

[0082] It should be noted that, in all embodiments of this application, before step S110 is implemented, the electronic atomizing device may be in a dormant state, i.e., the electronic atomizing device is already powered on; or it may be in a powered-off state. For example, when powered off, if a touch signal is detected by the touch sensor, or a physical button is pressed, the electronic atomizing device is powered on. In other embodiments, it may also be configured so that when the electronic atomizing device is powered off, touch signal detection, prediction, and heating actions are not performed.

[0083] In some alternative embodiments, in the above Figure 1 Based on the corresponding embodiments, such as Figure 6 As shown, it also includes the following steps:

[0084] S120, when the electronic atomizing device is detected to be triggered to perform a suction action, the heating module is controlled to heat the heated body with the third heating parameter value.

[0085] Specifically, the third heating parameter value corresponding to the first time period in the current suction action is greater than the product of the average heating parameter value of all time periods and the preset multiplier. The preset multiplier is greater than 1. As an example and not a limitation, the above preset multiplier can be 1.2, that is, the third heating parameter value corresponding to the first time period is greater than 1.2 times the average heating parameter value of all time periods.

[0086] In this embodiment, the third heating parameter value is the average heating power of the corresponding time period, that is, the average heating power within the corresponding time period. In other embodiments, the above-mentioned third heating parameter value can also be the average heating temperature of the corresponding time period, and this application does not limit this. In one possible implementation, the average heating power of all time periods is in the range of 8W-15W, and the average heating power of the first time period is in the range of 20W-25W.

[0087] In this embodiment, when heating is just started after the suction is triggered, the value of the third heating parameter corresponding to the first time period is controlled to be greater than the product of the average heating parameter value of all time periods of the suction action and the preset multiplier. That is, the heating body is heated with a larger heating power, which can make the heating body heat up quickly and the aerosol be released quickly. This allows a large amount of aerosol to be generated quickly when heating is started, so as to meet the user's need to obtain sufficient aerosol immediately and achieve a better taste experience.

[0088] On the other hand, in this embodiment, the third heating parameter values ​​are different for different time periods during the suction action, and the third heating parameter value for the later time period is smaller than the third heating parameter value for the previous time period in every two adjacent time periods. That is, during the heating process, the average heating power for all time periods shows a step-down trend, exhibiting a gradual decrease.

[0089] refer to Figure 7 It shows the power variation curves for all time periods during the heating process after the suction action is triggered, obtained experimentally. Curve a represents the average heating power for all time periods, curve b represents the target power for all time periods, i.e., the experimental reference value, and curve c represents the actual power for all time periods. Figure 7 It can be seen that during the heating process, the average heating power in all time periods shows a step-down trend, exhibiting a gradual decrease.

[0090] Current technologies cannot provide suitable heating temperatures for different heating stages. For example, as the composition of the medium changes during the heating process, higher temperatures are not needed in the later stages of heating, as excessively high temperatures can lead to the formation of harmful substances and deterioration of flavor and taste. This application reduces the heating power at the corresponding stages as the heating process progresses, thus avoiding this problem, ensuring that the medium composition has a suitable heating temperature at each stage, preventing the formation of harmful substances, and ensuring a better smoking experience.

[0091] In some alternative embodiments, the heating duration corresponding to the first time period is shorter than the third preset duration. This allows for a shorter duration of high power, avoiding problems such as over-baking of the heated object due to prolonged high-temperature heating, which could lead to the production of harmful substances and deterioration of flavor and texture. By way of example and not limitation, the third preset duration can be 2 seconds.

[0092] In some alternative embodiments, the maximum temperature of the heated body during the first time period is greater than the peak aerosol release temperature corresponding to the heated body. The peak aerosol release temperature is determined based on a first variation curve corresponding to the heated body. The first variation curve characterizes the relationship between the weight loss rate of the heated body and temperature. This allows the temperature to rise rapidly above the peak aerosol release temperature upon heating start-up, thereby quickly generating a large amount of aerosol to meet the user's need for sufficient aerosols immediately and achieve a better taste experience.

[0093] The peak temperature of aerosol release is the temperature corresponding to the maximum weight loss rate on the first variation curve within a preset temperature range. In one possible implementation, the peak temperature of aerosol release is set within the range of [250℃, 300℃]. For example, if the preset temperature range is [200℃, 400℃], and the temperature corresponding to the maximum weight loss rate on the first variation curve within this temperature range is 300℃, then the peak temperature of aerosol release is 300℃. The preset temperature range can be determined after conducting multiple tests on the heated body.

[0094] In some optional embodiments, at least one time point in all time periods has a deviation value greater than a preset deviation threshold between the heating power and the average heating parameter value corresponding to that time period. The deviation value is c, the average heating parameter value corresponding to that time period is a, and the absolute value of the difference between the heating power at that time point and a is b, satisfying: c = b / a. Furthermore, the heating duration corresponding to the heating power with a deviation value greater than the preset deviation threshold is less than a fourth preset duration. This second preset duration is less than the first preset duration mentioned above. As an example and not a limitation, the fourth preset duration can be 0.3 seconds.

[0095] That is, during the power control process at different time periods, there may be brief, rapidly rising control pulses or brief, rapidly falling control pulses, used for rapid heating or uniform heating of the medium at specific stages of the heating process. However, because their pulse duration is short, they will not affect the average heating power of the time period in which they occur. As an example and not a limitation, the preset deviation threshold can be 0.4, and this application is not limited thereto.

[0096] Optionally, the heating duration corresponding to the heating power with a deviation value greater than the preset deviation threshold is less than the heating duration corresponding to the first time period, so as to ensure that the duration of the control pulse that causes a brief and rapid drop or rise is short, so as not to affect the overall average heating power of the time period and to ensure the heating effect of the heated body.

[0097] In some alternative embodiments, the above-mentioned electronic atomizing device includes a PCBA (Printed Circuit Board Assembly), and the sensors disclosed in all the embodiments of this application are connected to the PCBA.

[0098] In any of the above embodiments of this application, the specific type of electronic atomizing device is not limited. For example, electronic atomizing devices include, but are not limited to, air humidifiers, medical atomizers, or electronic cigarettes.

[0099] The aerosol-generating matrix can be solid or gel-like.

[0100] The specific details regarding the solid aerosol generation matrix are as follows:

[0101] The aerosol-generating matrix may include plant components, adjuvant components, smoke-generating agent components, and binder components. Plant components can be one or more combinations of powders formed from crushed tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants. These plant components are used to generate aerosols containing alkaloids when heated.

[0102] In one embodiment, the aerosol generating matrix is ​​a one-piece molded structure. For example, the aerosol generating matrix can be a one-piece structure formed through processes such as injection molding, compression molding, or extrusion. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the mixture is pushed forward by the screw through the extruder barrel and screw, continuously passing through the die head to form products or semi-finished products of various cross-sections. The aerosol generating matrix formed by extrusion molding is strip-shaped. Thus, the aerosol generating matrix remains a one-piece medium after being heated and absorbed or after heating ceases, making it less prone to disintegration and falling off.

[0103] In one embodiment, the aerosol generating matrix can be generally columnar in structure. That is, the aerosol generating matrix is ​​generally elongated, and the longitudinal length of the aerosol generating matrix is ​​greater than the distance between any two points on its cross-section.

[0104] In a cross-section perpendicular to the longitudinal direction of the aerosol-generating matrix, the cross-sectional shape of the aerosol-generating matrix includes, but is not limited to, circular, elliptical, racetrack-shaped, or polygonal shapes. Taking a circular cross-sectional shape as an example, the aerosol-generating matrix is ​​roughly cylindrical, and the longitudinal direction of the aerosol-generating matrix is ​​the axis of the cylinder.

[0105] In one embodiment, the heating element is located on the outer periphery of the aerosol generating matrix, which is divided into multiple regions along the circumference, with each region corresponding to a heating element. This allows for selective heating of different regions along the circumference of the aerosol generating matrix by different heating elements, enabling the release of aerosols from different parts of the matrix. This results in fresher aerosols and a richer flavor for each inhalation.

[0106] In one embodiment, a cavity is formed inside the aerosol generating matrix, and a heating element is located in the cavity. The aerosol generating matrix is ​​divided into multiple regions along the circumference, with each region corresponding to a heating element. This allows for selective heating of different regions of the aerosol generating matrix using different heating elements.

[0107] In one embodiment, the aerosol generating matrix may have multiple media segments along its length, with each media segment corresponding to a heating element. This allows for the selective heating of different media segments of the aerosol generating matrix by using different heating elements.

[0108] In one embodiment, each electronic atomizing device contains multiple aerosol generating substrates. That is, there can be multiple aerosol generating substrates, with each substrate corresponding to a heating element. This allows different aerosol generating substrates to be selectively heated by different heating elements.

[0109] The specific details regarding the liquid aerosol generation matrix are as follows:

[0110] The liquid matrix can be a drug or other substance such as e-liquid. For example, the liquid matrix includes solvents and additives. Solvents include, but are not limited to, propylene glycol and / or glycerol. Additives can include nicotine salts, plant extracts, and / or flavor additives. Flavor additives can be fragrances and flavorings.

[0111] In one embodiment, the electronic atomizing device includes a substrate and a reservoir for storing a liquid aerosol generating matrix. The substrate includes multiple heating surfaces, each with a heating element. The substrate can guide the liquid aerosol generating matrix from the reservoir to the heating surface. For example, the substrate may have liquid guiding holes to guide the liquid aerosol generating matrix to the heating surface. In this way, different heating elements can heat the aerosol generating matrix on different heating surfaces.

[0112] The matrix can be a porous structure. A porous structure refers to a structure with multiple interconnected pores that communicate with the outer surface of the matrix. The pores in a porous structure facilitate the temporary storage of the liquid matrix and allow for its flow. The multiple pores in a porous structure can be arranged randomly; that is, the pores in a porous structure are generated randomly.

[0113] The matrix can be made of ceramic material. Ceramic materials have advantages such as good thermal conductivity and uniformity. For example, the matrix can be made of dense ceramic material or porous ceramic material. Porous ceramic material can be generated by high-temperature sintering of components such as aggregate, binder, and pore-forming agent. During the sintering process of porous ceramic, the pore-forming agent creates randomly arranged pores in the porous ceramic.

[0114] In some embodiments, when there are multiple heating elements, each heating element can be controlled independently. Independent control of each heating element means that each heating element can be individually controlled to turn on, off, or have its temperature adjusted. For example, if each heating element is powered independently, then independent control of each heating element can be achieved.

[0115] In some embodiments, the heating element can be a resistive heating structure. The heating element can be a heating wire, a heating mesh, or a heating plate.

[0116] In some embodiments, the electronic atomizing device includes a power supply unit for powering electrically powered components such as a heating module. The power supply unit includes, but is not limited to, devices capable of providing electrical energy, such as batteries. The power source includes, but is not limited to, batteries. The battery can be a disposable battery or a rechargeable battery.

[0117] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0118] It should be noted that the various method embodiments disclosed in this application can be freely combined, and the technical solutions obtained after free combination are also within the protection scope of this application.

[0119] Another embodiment of this application discloses an electronic atomizing device. For example... Figure 8 As shown, the electronic atomizing device, in addition to including a heating module 81, a passive component 82, and an active component 83, also includes a control module 84. The heating module and the control module are connected, and the control module is used to control the heating module. The active component drives the passive component to rotate via a heated body 85. The control module implements the control method disclosed in any of the above embodiments. Exemplarily, the control module can be an MCU (Microcontroller Unit), the passive component 82 can be a passive wheel, and the active component 83 can be an active wheel. It should be noted that... Figure 8 The number of passive components 82 shown is two, and the number of active components 83 is one, but this application is not limited thereto.

[0120] In one optional embodiment, the heating module includes a heating element and a resonant unit. The heating element and the heated body are correspondingly arranged for heating the heated body. The heating element and the heated body are disposed within a target space. The resonant unit is disposed opposite to the heating element and is used to generate a magnetic field in the target space to heat the heating element. The heating element can be in contact with the heated body, thereby achieving heat conduction. The resonant unit is an L (inductor) C (capacitor) resonant unit.

[0121] Optionally, such as Figure 9 As shown, the heating module includes a heating element 91, a resonant unit 92, a sampling unit 93, and a driving unit 94. The aforementioned control module is connected to the sampling unit and the driving unit, respectively. The sampling unit is used to sample the electrical parameters in the heating module. The sampling unit samples at least one parameter among voltage, current, and power in the circuit. The driving unit converts the power supply into a driving signal, driving the LC resonant unit to resonate and generate a magnetic field. The alternating magnetic field generated by the resonant unit spreads outwards. The heating element, being a metal structure, generates eddy currents due to the cutting of magnetic field lines, thus generating self-heat and heating the object being heated. For example, the heating element can be one of aluminum foil, tin foil, or stainless steel sheet.

[0122] Optionally, the aforementioned electronic atomizing device may further include a pressure sensor and a heated body movement distance detection module. The pressure sensor may be located at the inlet of the electronic atomizing device. The pressure sensor detects the pressure value at the inlet of the electronic atomizing device. When the pressure value at the inlet forms a negative pressure, the control module can determine that the electronic atomizing device has triggered a suction action. It should be noted that in other embodiments, physical devices such as buttons can also be used to determine whether the user has triggered a suction action or whether the suction has ended.

[0123] The heated body movement distance detection module is used to detect the movement distance of the heated body, mainly to determine its movement distance when the heated body is moved after the main heating stage. The heated body movement distance detection module can be located on one side of the heated body's movement trajectory. The detection methods of the heated body movement distance detection module include, but are not limited to, motion image recognition detection, infrared reflection detection of marking lines, and infrared transmission (medium perforation) detection.

[0124] In some alternative embodiments, the electronic atomizing device also includes a motor. The motor is connected to the active component and drives the active component to rotate. For example, the motor provides the active component with the power to retract by engaging with it, causing the heated element to move and retract in a fixed direction.

[0125] Optionally, after the electronic atomizing device is turned on, the heated body can be tightened to keep it in a straight state.

[0126] Optionally, after the heating process triggered by the inhalation action ends, the electronic atomizing device can either cease heating and enter standby or power-off mode, or it can enter a heat preservation mode with lower power to facilitate rapid aerosol generation and provide a suitable temperature for the next inhalation. If there is no inhalation for an extended period (e.g., 600 seconds), the heat preservation mode will be exited, and the device will automatically power off.

[0127] The electronic atomizing device provided in this application embodiment features a roll-up transmission structure designed for a thin, flexible heated body. This structure utilizes a passive component to store and transport the unheated heated body, while an active component houses the heated body and drives the passive component to rotate. Furthermore, when the device detects a tendency to be inhaled, it controls the heating module to heat the heated body, preheating it before the user inhales. This ensures better atomization of the heated body during the user's first inhale, generating sufficient aerosol volume at a suitable temperature to meet the user's immediate needs and achieve a superior taste experience.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
