[0015] As an example, the aerosol generating device further includes an airflow channel configured to allow at least a portion of the first aspirated component to pass through the second receiving cavity to reach the intake port.

[0016] As an example, the airflow channel extends in a straight line.

[0017] As an example, the aerosol generating device includes a first operating mode and a third operating mode, in which both the first load and the second load can be started and operated.

[0018] Specifically, in the first operating mode only of the first operating mode and the third operating mode, the controller is configured to control the operating power of the first load based on the ambient temperature.

[0019] As an example, the minimum operating power of the first load in the third operating mode is greater than or equal to its maximum operating power in the first operating mode.

[0020] As an example, in the first operating mode, the operating power of the first load is configured to be positively correlated with the ambient temperature.

[0021] As an example, in the first operating mode, the value P of the operating power of the first load satisfies:

[0022] P = a + (T - Tmin) / (Tmax - Tmin);

[0023] Where a is the base operating power of the first load, Tmax is the average of the highest temperature over N consecutive days, Tmin is the average of the lowest temperature over N consecutive days, 1≤N≤5, and T is the current ambient temperature.

[0024] As an example, in the first operating mode, the value P of the operating power of the first load satisfies: 5W≤P≤15W.

[0025] As an example, the aerosol generating device also includes an interactive element configured for user operation to select an operating mode.

[0028] The second suction component is configured to produce a constant target value in each operating mode or in the first operating mode.

[0029] As an example, the controller is configured to control the temperature sensor to collect the ambient temperature once every hour.

[0049] Please refer to Figure 1 and Figure 2 Some embodiments of this application provide an aerosol generating apparatus 100, including a first load 1, the first load 1 being used to generate a first suction component from a first aerosol generating matrix.

[0050] Furthermore, the aerosol generating apparatus 100 may also include a first receiving cavity 2 for receiving a first aerosol generating matrix, thereby enabling at least a portion of the first aerosol generating matrix to be retained in the aerosol generating apparatus 100.

[0051] The first aerosol generating matrix may be solid at room temperature. As an example, the first aerosol generating matrix includes a tobacco-containing material containing volatile tobacco flavor compounds, i.e., a first inhalation component, released from the first aerosol generating matrix upon heating. For example, the tobacco-containing material includes, but is not limited to, tobacco leaves, shredded tobacco, tobacco sticks, or tobacco pellets.

[0052] The first aerosol generating matrix can be a liquid at room temperature. For example, the first aerosol generating matrix may include a polyol; or, for example, the first aerosol generating matrix may include a fragrance solution capable of releasing fragrance components.

[0053] In some embodiments, the first aerosol generating matrix primarily comprises flavoring agents for providing aroma.

[0054] For example, flavoring agents may contain cooling agents. Cooling agents make the aerosol refreshing and cool, which helps to enhance the throat-soothing effect. Cooling agents include, but are not limited to, at least one of: N,2,3-trimethyl-2-isopropylbutyramide (WS-23), menthol, peppermint oil, and N-ethyl-p-menthyl-3-carboxamide (WS-3).

[0055] For example, flavorings may contain sweeteners. Sweeteners enhance the sweetness of aerosols, improving their flavor. Sweeteners include, but are not limited to, N-[N-(3,3-dimethylbutyl)]-L-α-aspartic-L-phenylalanine 1-methyl ester (also known as neotame). Sweeteners may also include, but are not limited to, one or more of the following: sucralose, steviol glycosides, neotame, acesulfame potassium, aspartame, glycyrrhizin, sodium saccharin, cyclamate, and monk fruit extract.

[0056] For example, flavoring agents can contain tobacco extracts. The main components of tobacco extracts include tobacco cellulose, tobacco leaf proteins, and other substances that impart a tobacco aroma, but do not contain nicotine or similar substances. Tobacco extracts can enhance the similarity between the smoke and traditional cigarette smoke, giving the aerosol a traditional cigarette flavor.

[0057] For example, flavoring agents may contain fragrances. Fragrances can reduce the irritation caused by tobacco extracts. Fragrances may include at least one of the following: 2-acetylpyrazine, ethyl maltol, and methyl dihydrojasmone. Fragrances may also include throat-soothing ingredients. Throat-soothing ingredients include, but are not limited to, at least one of the following: eugenol, clove leaf oil, clove bud oil, Peruvian balsam oil, fenugreek tincture, star anise oil, vanilla bean tincture, tea polyphenols, lemon oil, and propylene glycol.

[0058] The first aerosol generating matrix may contain at least two flavoring agents, so that the first inhaled component produced by it may contain at least two flavors. For example, the first aerosol generating matrix may contain both a cooling agent and a sweetener, or it may contain both a cooling agent and a tobacco extract, or it may contain both a sweetener and a flavoring.

[0059] The first aerosol generating matrix can also produce a first aspirated component with fruit, coffee, or other flavors.

[0060] In some embodiments, the aerosol generating device 100 further includes a temperature sensor 3 for detecting the ambient temperature. The temperature sensor 3 is a sensor capable of sensing temperature and converting it into a usable output signal. The temperature sensor 3 may include a contact temperature sensor. Preferably, the temperature sensor 3 includes a thermistor. The thermistor may be a positive temperature coefficient thermistor (PTC). The thermistor may be a negative temperature coefficient thermistor (NTC). The ambient temperature mainly refers to the temperature of the external environment where the aerosol generating device 100 is located. For example, the ambient temperature may be the air temperature of the environment where the aerosol generating device 100 is located, or for example, the room temperature of the room where the aerosol generating device 100 is located.

[0061] Therefore, the temperature sensor 3 can be disposed adjacent to the surface of the aerosol generating device 100, or at least a portion of the temperature sensor 3 can be exposed on the surface of the aerosol generating device 100. This makes the temperature sensor 3 more sensitive to changes in external temperature and more accurate in detecting ambient temperature.

[0062] In some embodiments, the aerosol generating device 100 further includes a housing 4, in which the first load 1 and the first receiving cavity 2 are both disposed.

[0063] The temperature sensor 3 can be located inside and in contact with the housing 4. Preferably, the portion of the housing 4 in contact with the temperature sensor 3 is made of a thermally conductive material. A thermally conductive material is understood to have a thermal conductivity of at least 10 W / (m·K) at 23°C and 50% relative humidity, preferably at least 40 W / (m·K), and more preferably at least 100 W / (m·K). Suitable thermally conductive materials include, but are not limited to: graphite, graphene, aluminum, copper, zinc, steel, silver, thermally conductive polymers, or any combination or alloy thereof.

[0064] You can refer to Figure 2 At least a portion of the temperature sensor 3 may be exposed outside the housing 4. For example, the housing 4 may have a through-hole in which at least a portion of the temperature sensor 3 is located.

[0065] You can refer to Figure 2 and Figure 3 The aerosol generating device 100 can be an electrosol generating device, including a power supply assembly. The power supply assembly can include any suitable battery 5. In one embodiment, the battery 5 is a lithium-ion battery. Alternatively, the battery 5 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. The power supply assembly can include a circuit board 6 and a controller 61 disposed on the circuit board 6. The controller 61 can control the power output of the battery 5, for example, causing the battery 5 to output alternating current or direct current, or, for example, causing the battery 5 to output current or voltage in pulse form.

[0066] The controller 61 can also control the overall operation of the aerosol generating device 100. Specifically, the controller 61 controls not only the operation of the battery 5 and the load, but also the operation of other components in the aerosol generating device 100. Furthermore, the controller 61 can determine whether the aerosol generating device 100 is operable by checking the status of its components. The controller 61 includes at least one processor. The processor may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. Moreover, those skilled in the art will understand that the controller 61 may include another type of hardware.

[0067] The first load 1 is able to receive electrical power provided by the power supply component, thereby causing the first aerosol matrix to vaporize and generate the first suction component.

[0068] The controller 61 can be configured to control the operating power of the first load 1 based on the ambient temperature, thereby adjusting the amount of the first aspirated component produced. More specifically, the controller 61 receives the ambient temperature from the temperature sensor 3, determines the corresponding electrical power based on the ambient temperature, and then controls the power supply component to output the electrical power to the first load 1. Thus, the controller 61 adjusts the amount of the first aspirated component produced in response to changes in the ambient temperature. Therefore, the amount of the first aspirated component produced varies under different ambient temperatures, providing users with different aspiration experiences.

[0069] In some embodiments, the aerosol generating apparatus 100 further includes a second load 7, which is used to generate a second suction component from the second aerosol generating matrix. The second suction component is different from the first suction component, thereby enabling the aerosol generating apparatus 100 to provide users with a richer suction experience.

[0070] Furthermore, the aerosol generating apparatus 100 may also include a second receiving cavity 8 for receiving a second aerosol generating matrix, thereby enabling at least a portion of the second aerosol generating matrix to be retained in the aerosol generating apparatus 100.

[0071] The second aerosol generating matrix can be a solid at room temperature. Alternatively, it can be a liquid at room temperature. Preferably, both the first and second aerosol generating matrices are liquids at room temperature.

[0072] In some embodiments, the second aerosol generating matrix comprises nicotine. Nicotine may include nicotine or nicotine salts. Nicotine has a neurostimulatory effect, used to provide the user with the pleasure of inhalation. The second inhalation component generated by the second aerosol generating matrix may contain nicotine.

[0073] In some embodiments, the aerosol generating device 100 further includes an air intake 9 for exporting an aerosol containing a first aspirable component and / or a second aspirable component. The air intake 9 is disposed on the nozzle 10 of the aerosol generating device 100, and is positioned facing the user's oral cavity when the user inhales through the nozzle 10, thereby enabling the first aspirable component and / or the second aspirable component to be drawn into the oral cavity through the air intake 9.

[0074] The first load 1 and the second load 7 can be electrically connected to the power supply component independently, so that the first load 1 and the second load 7 can work independently, so that the air inlet 9 of the aerosol generating device 100 can export a mixed aerosol containing both the first suction component and the second suction component, or an aerosol containing either the first suction component or the second suction component.

[0075] In some embodiments, the aerosol generating device 100 includes a first operating mode, in which both the first load 1 and the second load 7 can be activated. Thus, when the aerosol generating device 100 is in the first operating mode, it can generate both a first suction component and a second suction component, allowing the intake port 9 to discharge a mixed aerosol containing both the first and second suction components.

[0076] In some embodiments, in a first operating mode, the operating power of the first load 1 is configured to be positively correlated with the ambient temperature. In the first operating mode, the operating power of the first load 1 at higher ambient temperatures is greater than the operating power of the first load 1 at lower ambient temperatures. In the first operating mode, the amount of the first aspirated component produced at higher ambient temperatures is greater than the amount of the first aspirated component produced at lower ambient temperatures.

[0077] For example, the second aspirable component contains nicotine, and the first aspirable component contains a cooling agent. In the first operating mode, if a user moves from a cool indoor environment to a warm outdoor environment, the temperature sensor 3 detects an increase in ambient temperature. Based on this increased ambient temperature, the controller 61 controls the first load 1 to increase its operating power, thereby increasing the production of the first aspirable component. This allows the user to inhale more cooling aerosol in warmer outdoor environments, thus reducing discomfort to some extent.

[0078] Conversely, in the first working mode, if a user moves from an outdoor environment with a higher ambient temperature to an indoor environment with a lower ambient temperature, the temperature sensor 3 detects a decrease in ambient temperature. Based on the lower ambient temperature, the controller 61 controls the working power of the first load 1 to decrease, thereby reducing the amount of the first aspirated component produced. As a result, when the user is in an indoor environment with a lower ambient temperature, they can inhale aerosols with less of a cooling sensation.

[0079] Therefore, in the first operating mode, the controller 61 adjusts the operating power of the first load 1 based on the ambient temperature, which enables the user to have a usage experience that is in line with the ambient temperature.

[0080] In some embodiments, in the first operating mode, the value P of the operating power of the first load 1 satisfies:

[0081] P = a + (T - Tmin) / (Tmax - Tmin);

[0082] Where a is the reference operating power of the first load 1, which is a constant, Tmax is the average of the highest temperature over N consecutive days, Tmin is the average of the lowest temperature over N consecutive days, and 1≤N≤5.

[0083] In a typical example, the value of 'a' is 8, and N is 3. Temperature sensor 3 continuously collects temperature data for the three days preceding the day of use. Controller 61 can obtain the highest and lowest temperatures for each of these three days, and then calculate the average value of the highest temperature (Tmax) and the average value of the lowest temperature (Tmin) over these three consecutive days. Then, controller 61 obtains the current ambient temperature (T) from temperature sensor 3, and based on the above formula, calculates the value of P, and then controls battery 5 to provide the corresponding electrical power to the first load 1.

[0084] The controller 61 can control the temperature sensor 3 to collect the ambient temperature once every hour. Of course, depending on the accuracy requirements, the controller 61 can also control the temperature sensor 3 to collect the ambient temperature at a higher or lower frequency.

[0085] In some embodiments, in the first operating mode, the operating power P of the first load 1 satisfies: 5W ≤ P ≤ 15W, preferably 8W ≤ P ≤ 15W. Thus, in the first operating mode, although the controller 61 can adjust the operating power of the first load 1 based on the ambient temperature, the maximum operating power of the first load 1 does not exceed 15W, and the minimum operating power is not lower than 5W.

[0086] In some embodiments, the aerosol generating device 100 includes a third operating mode in which both the first load 1 and the second load 7 can be activated. Specifically, only in the first operating mode (both the first and third operating modes) can the controller 61 control the operating power of the first load 1 based on ambient temperature. In other words, in the third operating mode, the controller 61 cannot control the operating power of the first load 1 based on ambient temperature.

[0087] Furthermore, the minimum operating power of the first load 1 in the third operating mode is greater than or equal to its maximum operating power in the first operating mode.

[0088] When a user moves from one environment to another, such as from indoors to outdoors, and the ambient temperature changes significantly, if the controller 61 in the first working mode cannot meet the user's needs by adjusting the working power of the first load 1 based on the ambient temperature, the user can directly select the third working mode, which will cause the working power of the first load 1 to increase sharply, or cause the amount of the first suction component to increase sharply.

[0089] Alternatively, when the ambient temperature is relatively stable, the user can directly select the third working mode, which enables the aerosol generating device 100 to generate a relatively large amount of the first suction component to meet the user's suction needs at that time.

[0090] In the third operating mode, the target power of the first load 1 can be constant. This target value can be a specific numerical value; for example, in the third operating mode, the target power of the first load 1 can be 15W, meaning that in the third operating mode, the power of the first load 1 can be maintained at 15W. This target value can also be a range; for example, in the third operating mode, the target power of the first load 1 can be between 12W and 20W, meaning that in the third operating mode, the power of the first load 1 can be between 12W and 20W. The controller 61 can adjust the power of the first load 1 in the third operating mode based on factors other than ambient temperature.

[0091] In some embodiments, the aerosol generating device 100 includes a second operating mode, in which only the second load 7 can be activated during the second operating mode. In other words, in the second operating mode, the first load 1 is not activated, or the operating power of the first load 1 is 0W; in the second operating mode, the aerosol generated by the aerosol generating device 100 includes a second suction component but does not include a first suction component.

[0092] In some embodiments, the aerosol generating device 100 is configured to maintain a constant target value for the total amount of aspirated components generated in each operating mode, so as to ensure good consistency in the fullness of each aspirate.

[0093] Therefore, in the first working mode, since the aerosol generating device 100 can generate both the first and second aspirable components, if the controller 61 increases the operating power of the first load 1 based on the ambient temperature, thereby increasing the amount of the first aspirable component generated, then the operating power of the second load 7 can be reduced, thereby reducing the amount of the second aspirable component generated; conversely, if the controller 61 decreases the operating power of the first load 1 based on the ambient temperature, thereby reducing the amount of the first aspirable component generated, then the operating power of the second load 7 can be increased, thereby increasing the amount of the second aspirable component generated.

[0094] Alternatively, in the second operating mode, the first load 1 does not start working, thus not producing the first suction component, so the operating power of the second load 7 can be larger to produce a large amount of the second suction component.

[0095] Alternatively, in the third operating mode, the first load 1 operates at a higher power to generate a larger amount of the first suction component, so that the second load 7 can operate at a lower power to generate less of the second suction component.

[0096] In some embodiments, the second load 7 is configured to maintain a constant target power value in each operating mode or in the first operating mode; or, the second aspiration component is configured to maintain a constant target amount in each operating mode or in the first operating mode. This ensures that the second aspiration component is generated in each operating mode, and that the amount of the second aspiration component generated is the same. This allows the second aspiration component to provide the user with a relatively consistent sensory experience or neural stimulation in each operating mode. Especially when the second aspiration component contains nicotine, it can prevent nicotine levels from exceeding the limit in any operating mode.

[0097] It should be noted that in the first and third operating modes, the second load 7 is optional rather than mandatory. In other embodiments, the second load 7 may not be activated in the first and / or third operating modes, that is, the operating power of the second load may be 0W.

[0098] In some embodiments, the aerosol generating apparatus 100 further includes an interactive element 11 configured for user operation to select an operating mode.

[0099] Interactive element 11 may include a touch screen, knob, slide switch, button, remote control or keyboard.

[0100] When the interactive element 11 includes buttons, there can be one or more buttons. For example, when there are multiple buttons, each button can correspond to a working mode, so that when one of the buttons is triggered, the corresponding working mode is selected. For example, when there is one button, different working modes can be selected by long-pressing or short-pressing the button, or the working mode can be changed by pressing the button continuously.

[0101] When the interactive element 11 includes a slide switch, the aerosol generating device 100 is in a first working mode when the interactive element 11 is slid to a first position; the aerosol generating device 100 is in a second working mode when the interactive element 11 is slid to a second position; and the aerosol generating device 100 is in a third working mode when the interactive element 11 is slid to a third position.

[0102] In some embodiments, the aerosol generating apparatus 100 further includes an airflow channel 121 configured to allow at least a portion of the first aspirated component to pass through the second receiving cavity 8 and reach the intake port 9.

[0103] Furthermore, at least a portion of the second aspirated component can reach the intake port 9 through the airflow channel 121, and at least a portion of the first aspirated component can mix with at least a portion of the second aspirated component in the airflow channel 121 during the flow toward the intake port 9.

[0104] Furthermore, both the first load 1 and the second load 7 are disposed in the airflow channel 121, and the second load 7 is located downstream of the first load 1.

[0105] More specifically, the aerosol generating device 100 further includes a first housing 13, a second housing 14, and a guide tube 12 for defining at least a partial boundary of the airflow channel 121. A first receiving cavity 2 is disposed in the first housing 13, and a second receiving cavity 8 is disposed in the second housing 14. The guide tube 12 includes a first guide tube located in the first housing 13 and a second guide tube passing through the second receiving cavity 8. The first guide tube and the second guide tube are in fluid communication, and the second guide tube is located between the first guide tube and the suction port 9, so that the second guide tube can guide the first suction component to the suction port 9. The first guide tube may also pass through the first receiving cavity 2.

[0106] The proximal end of the air duct 12 is positioned towards and connected to the air inlet 9. Outside air can enter the air duct 12 from the distal end.

[0107] In some embodiments, the airflow channel 121 extends in a straight line.

[0108] In some embodiments, the first load 1 includes an ultrasonic element capable of high-frequency vibration under ultrasonic drive, thereby enabling the first load 1 to utilize ultrasonic vibration to vaporize the first aerosol matrix and form a first suction component.

[0109] In some embodiments, the first aerosol generating matrix is ​​liquid at room temperature. The first load 1 includes a first liquid-absorbing element 1-2 and a first heating element 1-1, which can be connected to the first liquid-absorbing element 1-2. The first liquid-absorbing element 1-2 can be a porous body, used to guide the first aerosol generating matrix into the atomization range of the first heating element 1-1. The first heating element 1-1 is used to heat the liquid matrix, causing it to vaporize and generate an aerosol. The porous body can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body can be porous ceramic or porous metal; this application does not limit the structure and composition of the porous body.

[0110] Furthermore, the aerosol generating device 100 also includes a liquid storage cotton (not shown), which is disposed in the first receiving cavity 2. The liquid storage cotton is used to absorb the liquid matrix, which helps to confine the first aerosol generating matrix in the first receiving cavity 2 within the liquid storage cotton, thereby preventing the first aerosol generating matrix from leaking out of the first receiving cavity 2. It should be noted that the liquid storage cotton is optional rather than mandatory.

[0111] In some embodiments, the second load 7 includes an ultrasonic element capable of high-frequency vibration under ultrasonic drive, thereby enabling the second load 7 to utilize ultrasonic vibration to vaporize the second aerosol matrix and form a second suction component.

[0112] In some embodiments, the second aerosol generating matrix is ​​liquid at room temperature. The second load 7 includes a second liquid-absorbing element 7-2 and a second heating element 7-1, which can be connected to the second liquid-absorbing element 7-2. The second liquid-absorbing element 7-2 can be a porous body used to guide the second aerosol generating matrix into the atomization range of the second heating element. The second heating element 7-1 is used to heat the liquid matrix, causing it to vaporize and generate an aerosol. The porous body can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body can also be porous ceramic or porous metal; this application does not limit the structure and composition of the porous body.

[0113] Furthermore, the aerosol generating device 100 also includes a liquid storage cotton (not shown), which is disposed in the second receiving cavity 8. The liquid storage cotton is used to absorb the liquid matrix, which helps to confine the second aerosol generating matrix in the second receiving cavity 8 within the liquid storage cotton, thereby preventing the second aerosol generating matrix from leaking out of the second receiving cavity 8. It should be noted that the liquid storage cotton is optional rather than mandatory.

[0114] In some embodiments, the first load 1 and the second load 7 have the same shape and structure.

[0115] Please refer to Figure 4 Some embodiments of this application provide a control method for an aerosol generating device 100, the method comprising:

[0116] Receives the ambient temperature from temperature sensor 3;

[0117] The corresponding electrical power is determined based on the ambient temperature.

[0118] The power supply component is controlled to output electrical power to the first load 1, thereby adjusting the amount of the first suction component produced in response to changes in ambient temperature.

[0119] Before the controller 61 receives the ambient temperature, the controller 61 can also control the temperature sensor 3 to obtain the ambient temperature.

[0120] Before the controller 61 controls the temperature sensor 3 to acquire the ambient temperature, the controller 61 can first acquire the operating mode selected by the interactive element 11. In the first operating mode, the controller 61 controls the temperature sensor 3 to acquire the ambient temperature, and then controls the operating power of the first load 1 based on the ambient temperature. In the second operating mode, the controller 61 controls the operating power of the first load 1 to 0W, or controls the first load 1 to not start operating, and the controller 61 can also control the temperature sensor 3 to not start operating. In the third operating mode, the controller 61 controls the first load 1 to operate at a higher power, such that the minimum operating power of the first load 1 in the third operating mode is greater than the maximum operating power of the first load 1 in the second operating mode, and the controller 61 can also control the temperature sensor 3 to not start operating.

[0121] In the first to third working modes, the controller 61 can also control the second load 2 to start working, thereby generating the second suction component.

[0122] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
