Summary of the Invention

[0003] This application provides an electronic atomizing device that enables the movement control and storage of a thin sheet-like medium within a limited internal space.

[0015] In one possible implementation of the first aspect, the control module is further configured to control the heating module to heat the heated body when the electronic atomizing device is detected to have a tendency to be drawn in.

[0016] In one possible implementation of the first aspect, the control module is further configured to detect whether the electronic atomizing device has a tendency to be drawn in, based on one or more sensors in a preset sensor combination; the preset sensor combination includes: a multi-axis accelerometer, a multi-axis gyroscope, an image sensor, and an infrared temperature sensor.

[0017] In one possible implementation of the first aspect, the control module is further configured to control the heating module to heat the heated body sequentially with a first heating parameter value and a second heating parameter value when the electronic atomizing device is detected to have a tendency to be drawn in; wherein, the temperature rise of the heated body per unit time when heated based on the first heating parameter value is greater than the temperature rise of the heated body per unit time when heated based on the second heating parameter value.

[0036] 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.

[0037] like Figure 1As shown, one embodiment of this application provides an electronic atomizing device, including: a passive component 11, an active component 12, a heating module 13, and a control module 14. The heating module 13 and the control module 14 are connected.

[0038] The active component 12 is used to receive the heated object 15 and to drive the passive component 11 to rotate via the heated object 15. The passive component 11 is used to store and transport the unheated object 15. The heating module 13 is used to heat the object 15 to generate an aerosol. The heating module 13 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. For example, the control module 14 can be an MCU (Microcontroller Unit), the passive component 11 can be a passive wheel, and the active component 12 can be an active wheel. It should be noted that... Figure 1 The number of passive components shown is two, and the number of active components 12 is one, but this application is not limited thereto.

[0039] 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.

[0040] The aerosol generating matrix is ​​used to generate aerosols by being heated by a heating element. For example, 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.

[0041] In this embodiment, the control module is configured to control the heating module to heat the object with heating parameter values ​​when the electronic atomization device is detected to be triggered for inhalation. Specifically, the heating parameter values ​​differ for different time periods within the inhalation action, and the heating parameter value for the later time period is lower than that for the previous time period. That is, during the heating process, the average heating power across all time periods exhibits a step-down trend, showing a gradual decrease.

[0042] In this embodiment, the heating parameter value is the average heating power over the corresponding time period, that is, the average heating power within the corresponding time period. In other embodiments, the heating parameter value may also be the average heating temperature over the corresponding time period, and this application does not impose any restrictions on this.

[0043] refer to Figure 2 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 2 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.

[0044] 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.

[0045] In some alternative embodiments, the heating duration corresponding to the first time period is shorter than the first 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 first preset duration can be 2 seconds.

[0046] 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.

[0047] 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.

[0048] 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 second preset duration. This second preset duration is less than the first preset duration mentioned above. As an example and not a limitation, the second preset duration can be 0.3 seconds.

[0049] That is, during the power control process at different time periods, there may be a brief, rapidly rising control pulse 31 (such as...). Figure 3 As shown), there may also be a brief, rapid drop in control pulse 41 (such as...). Figure 4 As shown, it is used for rapid heating or uniform heating of the medium at a specific stage of the heating process, but because its pulse time is short, it will not affect the average heating power of the time period in which that moment occurs. As an example and not a limitation, the preset deviation threshold can be 0.4, and this application is not limited thereto.

[0050] 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.

[0051] In some alternative embodiments, based on any of the above embodiments, the 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 a preset multiplier. The preset multiplier is greater than 1. As an example and not a limitation, the preset multiplier can be 1.2, that is, the heating parameter value corresponding to the first time period is greater than 1.2 times the average heating parameter value of all time periods.

[0052] In this embodiment, the heating parameter value is the average heating power for the corresponding time period, that is, the average heating power within the corresponding time period. In other embodiments, the above heating parameter value can also be the average heating temperature for the corresponding time period, and this application does not limit this. In one possible implementation, the average heating power for all time periods ranges from 8W to 15W, and the average heating power for the first time period ranges from 20W to 25W.

[0053] This embodiment controls the heating parameter value corresponding to the first time period to be greater than the product of the average heating parameter value of all time periods of the current suction action and the preset multiplier when heating is just started after the suction is triggered. In other words, 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.

[0054] In some optional embodiments, the control module is further configured to, when it detects that the heating module has stopped heating, control the heated object to move a preset distance after a preset time delay, so that the unheated heated object is placed in the heating area of ​​the heating module. In this embodiment, moving the heated object after a preset time delay can prevent the temperature of the just-heated heated object from becoming too high and damaging the internal components of the electronic atomizing device. Moving the heated object a preset distance after heating ends can prevent the heated object from being reheated, thus avoiding the generation of harmful substances. The preset time period and preset distance can be set as needed, and this application does not limit them. The preset time period can be any value from 0 to 5 seconds.

[0055] Optionally, the control module is further configured to control the heating module to stop heating when it detects that the electronic atomizing device meets at least one condition in a preset trigger condition group. The conditions in the preset trigger condition group include:

[0056] The pressure at the inlet of the electronic atomizing device is the same as the ambient air pressure.

[0057] The duration of the suction action exceeds the preset maximum duration.

[0058] An abnormality in heating was determined based on the electrical parameters of the electronic atomization device.

[0059] In some optional embodiments, the control module is configured to heat the heated body while simultaneously controlling its movement when the preset physical parameters of the heated body meet a second preset condition. The second preset condition can be that the thickness of the heated body is less than a preset thickness threshold, or that the heating area of ​​the heated body is greater than a corresponding preset area threshold. In this case, heating can be performed while the heated body is moved, ensuring sufficient heating of the heated body while maintaining a relatively stable amount of aerosol generated, thus guaranteeing a good and consistent suction experience for the user. In other embodiments, the heated body can also remain stationary when heating is initiated after the suction action is triggered.

[0060] In some optional embodiments, the control module is configured to control the heating module to heat the heating element when it detects a tendency for the electronic atomizing device to be inhaled. This allows for preheating of the heating element before the user inhales, increasing its temperature before inhalation. This ensures better atomization of the heated element during the user's first inhalation, resulting in a sufficient amount of aerosol produced at a suitable temperature to meet user needs and achieve a better taste experience. Furthermore, in this embodiment, the amount of aerosol released during preheating needs to be sufficiently small (e.g., less than 2.5 mg) to guarantee a good user experience.

[0061] The method for determining the inhalation tendency can be based on one or more sensors from a preset sensor combination. Alternatively, the motion trend of the electronic atomizing device can be estimated by measuring changes in acceleration, tilt angle, and rotation angle in multiple directions, thereby determining whether the user is preparing to inhale (i.e., exhibiting an inhalation tendency). The preset sensor combination includes a multi-axis accelerometer, a multi-axis gyroscope, an image sensor, and an infrared temperature sensor. Detection can be achieved by determining whether a face is close to the electronic atomizing device using either an image or sensor; or by combining multi-axis accelerometer and multi-axis gyroscope. This application does not impose any limitations on this method.

[0062] In one embodiment, the control module is configured to control the heating module to heat the heated body with a first heating parameter value or a second heating parameter value when the electronic atomizing device is detected to have a tendency to be drawn in, or to control the heating module to heat the heated body with the first heating parameter value and the second heating parameter value in sequence.

[0063] 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 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 temporary suction needs.

[0064] 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.

[0065] Specifically, in this embodiment, the heating process of the heated body includes two stages: a preheating stage and a main heating stage. The preheating stage is triggered by detecting a tendency to be drawn into the electronic atomizing device. This tendency can be determined 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 it has a tendency to be drawn into the device. Otherwise, it is determined that it does not have a tendency to be drawn into the device. In some optional embodiments, a gravity sensor can also be used to detect the gripping posture of the electronic atomizing device and changes in the capacitance value of some preset gripping points to detect whether a tendency to be drawn into the device is present; this will not be elaborated further here. The main heating stage is triggered by detecting a drawn-in action of the electronic atomizing device. Specifically, this 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 the ambient air pressure) is formed at the inlet, a drawn-in action is determined to be triggered.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] In some optional embodiments, both the first heating parameter value and the second heating parameter value are less than the heating parameter value during the first time period after the electronic atomizing device is triggered to inhale. Optionally, the heating parameter value during the first time period after the electronic atomizing device is triggered to inhale is greater than a second preset power threshold. The second preset power threshold is greater than the first preset power threshold. This ensures that a large amount of aerosol is rapidly generated when heating starts after the inhale is triggered, improving the user's taste experience.

[0070] This allows the temperature to rapidly rise above the critical temperature for aerosol generation immediately upon the start of main heating, quickly generating a large amount of aerosol and improving the user's inhalation experience. As an example, and not a limitation, the heating element is heated at an average power of 15W for the first 0.5 seconds of the main heating phase, rapidly raising its temperature to above 220°C. Then, this average heating power is reduced, for example, to 10W, until the main heating phase ends. The main heating phase ends when no inhalation is detected, such as when a pressure sensor detects that the pressure at the inhalation port of the electronic atomizer has returned to ambient pressure; or when heating stops when the duration since the start of autonomous heating reaches a preset time threshold. This preset time threshold is greater than the typical inhalation duration for a single user session.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] In some alternative embodiments, the electronic atomizer can be powered on via a physical button or triggered by a sensor. For example, the casing of the electronic atomizer may have a touch sensor, and the control module may be configured to control the electronic atomizer to start when a touch signal is detected by the touch sensor.

[0075] Optionally, after the electronic atomizing device is turned on, the heated body can be tightened to keep it in a straight state.

[0076] 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.

[0077] In some optional embodiments, 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.

[0078] Optionally, such as Figure 6 As shown, the heating module includes a heating element 61, a resonant unit 62, a sampling unit 63, and a driving unit 64. The control module can be 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 resonant unit to generate a magnetic field. The alternating magnetic field generated by the resonant unit spreads outwards. The heating element is a metal structure; the heating element generates eddy currents due to the cutting of magnetic field lines, thereby generating self-heat and heating the heated object. For example, the heating element can be one of aluminum foil, tin foil, or stainless steel sheet.

[0079] 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.

[0080] The aerosol-generating matrix can be solid or gel-like.

[0081] The specific details regarding the solid aerosol generation matrix are as follows:

[0082] 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.

[0083] 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.

[0084] In one embodiment, the aerosol generating matrix can be generally columnar in structure. Furthermore, the aerosol generating matrix is ​​generally elongated and flexible, with its longitudinal length greater than the distance between any two points on its cross-section.

[0085] 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, flat, elliptical, racetrack-shaped, or polygonal shapes.

[0086] 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.

[0087] 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.

[0088] It should be noted that all the embodiments disclosed above in this application can be combined in any way, and the technical solutions obtained after the combination are also within the protection scope of this application.
