However, the first aerosol generated by the first nebulizer needs to pass through the rear of the second nebulizer to flow into the third nebulizer. When the second nebulizer is working, the aerosol flowing into the third nebulizer is a mixture of the first aerosol and the second aerosol; when the second nebulizer is not working, the first aerosol will condense in large quantities when flowing through the second nebulizer. Thus, regardless of whether the second nebulizer is working or not, the first aerosol will be affected by the second nebulizer when flowing through the second nebulizer. Utility Model Content

[0052] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] The terms "first", "second" and "third" in this application are only used for descriptive purposes and cannot be understood as indicating or suggesting relative importance or implicitly indicating the quantity or order of the indicated technical features. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative position relationship or movement situation between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or equipment that includes a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or equipment.

[0054] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0055] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be one or more intermediate elements in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0056] Please refer to Figure 1 and Figure 2 , the present application provides an embodiment of an aerosol generating device 100, the aerosol generating device 100 includes a plurality of atomizers. It should be noted that, as described in the present application, "plurality" refers to a number of two or more. Figure 2 In the illustrated embodiment, the aerosol generating device 100 includes three atomizers, namely a first atomizer 1 , a second atomizer 2 and a third atomizer 3 .

[0057] In some embodiments, reference may be made to Figure 2 and Figure 4 The first nebulizer 1 includes a first storage chamber for storing a first aerosol-generating substrate and a first atomization assembly 11 for atomizing the first aerosol-generating substrate to generate a first aerosol; the second nebulizer 2 includes a second storage chamber for storing a second aerosol-generating substrate and a second atomization assembly 21 for atomizing the second aerosol-generating substrate to generate a second aerosol; the third nebulizer 3 includes a third storage chamber for storing a third aerosol-generating substrate and a third atomization assembly 31 for atomizing the third aerosol-generating substrate to generate a third aerosol.

[0058] The second atomizer 2 and the third atomizer 3 are independently and separately in fluid communication with the first atomizer 1, and the first atomizer 1 is located downstream of the second atomizer 2 and the third atomizer 3 in the direction of airflow. This allows the second atomizer 2 and the third atomizer 3 to be at the same level and not in an upstream-downstream relationship. Therefore, the second aerosol generated by the second atomizer 2 can flow into the downstream first atomizer 1 without passing through the third atomizer 3, and the third aerosol generated by the third atomizer 3 can flow into the downstream first atomizer 1 without passing through the second atomizer 2.

[0059] In some embodiments, at least two of the first, second and third aerosol-generating substrates may be different, such that at least two of the first, second and third aerosols may have different flavours.

[0060] In some embodiments, the first aerosol-generating substrate comprises nicotine. Nicotine may include nicotine or a nicotine salt. Nicotine has a neurostimulating effect, providing a pleasurable sensation to the user upon inhalation. The first aerosol generated by the first aerosol-generating substrate contains nicotine.

[0061] In some embodiments, the second aerosol-generating substrate primarily comprises flavoring agents for providing fragrance or adjusting taste.

[0062] For example, the second aerosol-generating substrate may include a cooling agent. This cooling agent can provide a refreshing and cooling aerosol, thereby enhancing 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).

[0063] For example, the second aerosol-generating substrate may include a sweetener. The sweetener can enhance the sweetness of the aerosol, improving its flavor. Sweeteners include, but are not limited to, N-[N-(3,3-dimethylbutyl)]-L-α-aspartame-L-phenylalanine 1-methyl ester (also known as neotame). Sweeteners may also include, but are not limited to, one or more of sucralose, steviol glycosides, neotame, acesulfame potassium, aspartame, glycyrrhizin, saccharin sodium, cyclamate, and monk fruit sweetener.

[0064] For example, the second aerosol-generating substrate may include tobacco extract. The main components of tobacco extract include tobacco cellulose, tobacco leaf protein, and other substances that have a tobacco aroma, but do not contain nicotine or nicotine-like substances. Tobacco extract can enhance the similarity of the smoke to traditional cigarette smoke, giving the aerosol a traditional cigarette flavor.

[0065] For example, the second aerosol-generating substrate may contain a flavor. The flavor can reduce the irritation caused by the tobacco extract. The flavor may include at least one of 2-acetylpyrazine, ethyl maltol, and methyl dihydrojasmonate. The flavor may also include a throat-soothing ingredient. Throat-soothing ingredients include, but are not limited to, at least one of 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.

[0066] In some examples, the second aerosol-generating substrate may contain at least two flavoring agents simultaneously, so that the second aerosol generated thereby may contain at least two flavors. For example, the second aerosol-generating substrate may contain both a cooling agent and a sweetener, or may contain both a cooling agent and a tobacco extract, or may contain both a sweetener and a flavoring.

[0067] The second aerosol generated by the second aerosol-generating substrate may also have a fruit flavor, a coffee flavor, or other flavors.

[0068] The third aerosol-generating substrate primarily comprises a flavoring agent for providing fragrance or adjusting flavor. The third aerosol-generating substrate may be the same as or different from the second aerosol-generating substrate. Thus, the flavor of the second aerosol may be the same as or different from the flavor of the third aerosol.

[0069] In some embodiments, the first, second, and third aerosol-generating substrates are different from one another, resulting in different flavors for the first, second, and third aerosols. Thus, the aerosol-generating device 100 is capable of outputting at least seven flavors. For example, the device 100 may output at least three aerosols of a single flavor: the first, second, and third aerosols. It may also output a mixed aerosol containing any two of the first, second, and third aerosols. Alternatively, it may output a mixed aerosol containing all three aerosols: the first, second, and third aerosols. Alternatively, it may output a mixed aerosol containing all three aerosols: the first, second, and third aerosols.

[0070] In other embodiments, the first aerosol-generating substrate, the second aerosol-generating substrate, and the third aerosol-generating substrate are the same, or the flavor of the first aerosol, the second aerosol, and the third aerosol are the same, so that the more atomizers are involved in the operation of the first atomizer 1, the second atomizer 2, and the third atomizer 3, the greater the amount of aerosol generated per unit time by the aerosol generating device 100.

[0071] In some embodiments, the first aerosol-generating substrate is a liquid substrate, and the first atomizing assembly includes an ultrasonic element capable of high-frequency vibration under ultrasonic drive, so that the first atomizing assembly can utilize ultrasonic vibration to atomize the liquid substrate to form aerosol.

[0072] In some embodiments, reference may be made to Figure 4The first aerosol-generating matrix is ​​a liquid matrix. The first atomizing assembly 11 includes a first liquid-absorbing element 111 and a first heating element 112. The first heating element 112 can be connected to the first liquid-absorbing element 111 or in contact with the first liquid-absorbing element 111. The first liquid-absorbing element 111 can be a porous body, used to guide the liquid matrix into the atomization range of the first heating element 112. The first heating element 112 is used to heat the liquid matrix so that the liquid matrix is ​​atomized, thereby generating aerosol. The porous body can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber or nylon fiber. The porous body can be a porous ceramic or porous metal. This application does not limit the structure and composition of the porous body.

[0073] Furthermore, the first atomizer 1 further includes a liquid reservoir 4 disposed in the first storage chamber. The liquid reservoir 4 is used to absorb the liquid matrix, thereby helping to confine the liquid matrix in the first storage chamber within the liquid reservoir 4, thereby preventing the liquid matrix from leaking out of the first storage chamber. It should be noted that the liquid reservoir 4 is optional and not required.

[0074] In some embodiments, the aerosol generating device 100 further includes a power supply assembly 5, which is electrically connected to the first heating element 112 to provide electrical power for heating the first heating element 112. The power supply assembly includes a power supply, which can be any suitable battery. For example, the power supply includes a lithium battery, a rechargeable battery, or a disposable battery.

[0075] The power supply assembly also includes a controller that is electrically connected to the power supply. The controller can obtain its operating voltage from the power supply and control the power output of the power supply.

[0076] In some embodiments, the controller can control the electrical power output of the power supply to the first heating element 112 , thereby controlling the amount of the first aerosol generated by the first atomizer 1 per unit time.

[0077] In some embodiments, the first atomizer assembly 11 includes both a first heating element 112 and a second heating element 113. The first heating element 112 and the second heating element 113 can be connected to or in contact with the same first liquid-absorbing element 111. Alternatively, the first heating element 112 and the second heating element 113 can be connected to two independent first liquid-absorbing elements 111.

[0078] The first heating element 112 and the second heating element 113 can be arranged along the direction in which the first channel 13 in the first atomizer 1 extends, or can be arranged along the direction of the airflow in the first atomizer 1 during inhalation, or can be arranged along the extension direction of the first liquid-absorbing element 111, so that the first heating element 112 and the second heating element 113 can have no overlap in the arrangement direction, or the first heating element 112 and the second heating element 113 can only partially overlap in the arrangement direction. In this way, when the first heating element 112 and the second heating element 113 are working simultaneously, the first atomization assembly 11 can have a larger atomization area, thereby increasing the amount of the first aerosol produced per unit time.

[0079] In some embodiments, the first atomizer 1 includes a positive electrode and a negative electrode, and the positive electrode and the negative electrode of the first atomizer 1 are electrically connected to the positive and negative electrodes of a power supply, respectively. The first heating element 112 and the second heating element 113 can be connected in parallel between the positive and negative electrodes. Thus, the first heating element 112 and the second heating element 113 can generate and stop generating heat simultaneously.

[0080] In some embodiments, the power supply assembly 5 is configured to independently provide electrical power to the first heating element 112 and the second heating element 113 , so that the first heating element 112 and the second heating element 113 can operate and be controlled independently.

[0081] For example, the first atomizer 1 includes a first electrode, a second electrode, and a third electrode, wherein the first electrode is a positive electrode, and the second and third electrodes are independent negative electrodes. The first heating element 112 is electrically connected between the first and second electrodes, and the second heating element 113 is electrically connected between the first and third electrodes. Thus, the controller can control the power supply to independently provide electrical power to the first heating element 112 and the second heating element 113, so that either the first heating element 112 or the second heating element 113 can generate heat independently, so that the first heating element 112 and the second heating element 113 can generate heat simultaneously, and so that the first heating element 112 and the second heating element 113 can generate heat at different voltages or currents.

[0082] For example, the first atomizer 1 includes a first electrode, a second electrode, and a third electrode, wherein the first electrode and the third electrode are independent positive electrodes, and the second electrode is a negative electrode. The first heating element 112 is electrically connected between the first electrode and the second electrode, and the second heating element 113 is electrically connected between the second electrode and the third electrode.

[0083] In some embodiments, the first heating element 112 and the second heating element 113 may have substantially the same resistive material and the same initial resistance; the first heating element 112 and the second heating element 113 may have substantially the same shape structure; the first heating element 112 and the second heating element 113 may have substantially the same size.

[0084] In some embodiments, the second aerosol-generating substrate is a liquid substrate, and the second atomizing assembly includes an ultrasonic element capable of high-frequency vibration under ultrasonic drive.

[0085] In some embodiments, reference may be made to Figure 4 The second aerosol-generating substrate is a liquid substrate. The second atomizing assembly 21 includes a third liquid-absorbing element 211 and a third heating element 212. The third heating element 212 can be connected to or in contact with the third liquid-absorbing element 211. The third liquid-absorbing element 211 can be a porous body, which is used to guide the liquid substrate into the atomization range of the third heating element 212.

[0086] The second atomizer 2 may also include liquid storage cotton 4 for absorbing the liquid matrix.

[0087] In some embodiments, the power supply assembly 5 is electrically connected to the third heating element 212 , and the controller can control the power output of the power supply to the third heating element 212 , thereby controlling the amount of the second aerosol generated by the second atomizer 2 per unit time.

[0088] In some embodiments, the second atomizing assembly 21 includes both a third heating element 212 and a fourth heating element 213. The third heating element 212 and the fourth heating element 213 can be connected to the same third liquid absorbing element 211. Alternatively, the third heating element 212 and the fourth heating element 213 can be connected to two independent third liquid absorbing elements 211.

[0089] The third heating element 212 and the fourth heating element 213 can be arranged along the direction in which the third channel 22 in the second atomizer 2 extends, or along the direction of the airflow in the second atomizer 2 during inhalation, or along the direction in which the third liquid absorbing element 211 extends. In this way, when the third heating element 212 and the fourth heating element 213 operate simultaneously, the second atomizing assembly 21 can have a larger atomization area, thereby increasing the amount of second aerosol generated per unit time.

[0090] In some embodiments, the second atomizer 2 includes a positive electrode and a negative electrode, and the positive electrode and the negative electrode of the second atomizer are electrically connected to the positive electrode and the negative electrode of the power supply respectively. The third heating element 212 and the fourth heating element 213 can be connected in parallel between the positive electrode and the negative electrode.

[0091] In some embodiments, the power supply assembly 5 is configured to independently provide electrical power to the third heating element 212 and the fourth heating element 213 , so that the third heating element 212 and the fourth heating element 213 can independently operate and be independently controlled.

[0092] The third heating element 212 and the fourth heating element 213 may have substantially the same resistance; the third heating element 212 and the fourth heating element 213 may have substantially the same shape and structure; the third heating element 212 and the fourth heating element 213 may have substantially the same size.

[0093] In some embodiments, the third aerosol-generating substrate is a liquid substrate, and the third atomizing assembly includes an ultrasonic element capable of high-frequency vibration under ultrasonic drive.

[0094] In some embodiments, the third aerosol-generating substrate is a liquid substrate, and the third atomizing assembly 31 includes a fourth liquid-absorbing element 311 and a fifth heating element 312. The fifth heating element 312 can be connected to the fourth liquid-absorbing element 311. The fourth liquid-absorbing element 311 can be a porous body, which is used to guide the liquid substrate into the atomization range of the fifth heating element 312.

[0095] The third atomizer 3 may also include liquid storage cotton 4 for absorbing the liquid matrix.

[0096] In some embodiments, the power supply assembly 5 is electrically connected to the fifth heating element 312 , and the controller can control the power output of the power supply to the fifth heating element 312 , thereby controlling the amount of the third aerosol generated by the third atomizer 3 per unit time.

[0097] In some embodiments, the third atomizing assembly 31 includes both a fifth heating element 312 and a sixth heating element 313. The fifth heating element 312 and the sixth heating element 313 can be connected to the same fourth liquid aspirating element 311. Alternatively, the fifth heating element 312 and the sixth heating element 313 can be connected to two independent fourth liquid aspirating elements 311.

[0098] The fifth heating element 312 and the sixth heating element 313 can be arranged along the direction in which the fourth channel 32 in the third atomizer 3 extends, or along the direction of the airflow in the third atomizer 3 during inhalation, or along the direction in which the fourth liquid-absorbing element 311 extends. In this way, when the fifth heating element 312 and the sixth heating element 313 operate simultaneously, the third atomizing assembly 31 can have a larger atomization area, thereby increasing the amount of the third aerosol produced per unit time.

[0099] In some embodiments, the third atomizer 3 includes a positive electrode and a negative electrode, and the positive electrode and the negative electrode of the third atomizer 3 are respectively used to electrically connect to the positive electrode and the negative electrode of the power supply. The fifth heating element 312 and the sixth heating element 313 can be connected in parallel between the positive electrode and the negative electrode.

[0100] In some embodiments, the power supply assembly is configured to independently provide electrical power to the fifth heating element 312 and the sixth heating element 313 , so that the fifth heating element 312 and the sixth heating element 313 can independently operate and be independently controlled.

[0101] The fifth heating element 312 and the sixth heating element 313 may have substantially the same resistance material and the same initial resistance; the fifth heating element 312 and the sixth heating element 313 may have substantially the same shape structure; the fifth heating element 312 and the sixth heating element 313 may have substantially the same size.

[0102] In some embodiments, the first nebulizer 1 , the second nebulizer 2 , and the third nebulizer 3 are independently electrically connected to the power supply assembly 5 , so that the power supply assembly 5 can independently provide electrical power to the first nebulizer 1 , the second nebulizer 2 , and the third nebulizer 3 .

[0103] Therefore, any one of the first atomizer 1, the second atomizer 2 and the third atomizer 3 can work independently to generate only one aerosol among the first aerosol, the second aerosol and the third aerosol; or, any two of the first atomizer 1, the second aerosol 2 and the third aerosol 3 can work simultaneously to generate a mixed aerosol containing any two aerosols among the first aerosol, the second aerosol and the third aerosol; or, the first atomizer 1, the second aerosol 2 and the third aerosol 3 can work simultaneously to generate a mixed aerosol containing the first aerosol, the second aerosol and the third aerosol.

[0104] In some embodiments, the aerosol generating device 100 further includes an operating member 6 , which is configured to be operated by a user to adjust the electrical power provided by the power supply assembly 5 to the first atomizer 1 , the second atomizer 2 , and the third atomizer 3 .

[0105] In some embodiments, the aerosol generating device 100 includes multiple operating modes. The operating modes include the ratio of the aerosol volume generated by the corresponding atomizer to the total aerosol volume, so that different operating modes can provide different inhalation experiences for the user.

[0106] The working mode may include one or more preset modes. A preset mode is a pre-set mode, and the user can select a preset mode through the operating element 2 on the aerosol generating device 100, but cannot modify the content of the preset mode.

[0107] In some embodiments, the preset mode includes at least two of the seven preset modes in Table 1. In the first to seventh preset modes, the aerosol volume ratios (ratios between the aerosol volume and the total aerosol volume) of the first aerosol, the second aerosol, and the third aerosol are as shown in Table 1:

[0108] Preset Mode The proportion of the first aerosol The proportion of the second aerosol The proportion of the third aerosol First preset mode 100％ 0％ 0％ Second preset mode a1％ a2％ 0％ Third preset mode a3％ 0％ a4％ Fourth preset mode 0％ a5％ a6％ Fifth preset mode a7％ a8％ a9％ Sixth preset mode 0％ 100％ 0％ Seventh preset mode 0％ 0％ 100％

[0109] The sum of a1 and a2 equals 100. The sum of a3 and a4 equals 100. The sum of a5 and a6 equals 100. The sum of a7, a8, and a9 equals 100.

[0110] The values ​​of at least two of a1-a9 may be different, or the values ​​of at least two of a1-a9 may be the same.

[0111] The user sets or selects a preset mode through the operating member 2, and then the aerosol generating device 100 outputs an aerosol that conforms to the preset mode (the aerosol output by the aerosol generating device 100 may include a single aerosol or a mixed aerosol formed by a mixture of multiple aerosols). Thus, the user can change the puffing taste after changing the preset mode, obtaining a different puffing experience.

[0112] The total amount of aerosol generated by at least two of the plurality of preset modes may be the same. The total amount of aerosol generated by at least two of the plurality of preset modes may be different.

[0113] In some embodiments, the aerosol generating device 100 further includes a memory, in which data associated with the contents of the preset mode is stored. The controller in the aerosol generating device 100 can read the data associated with the current preset mode stored in the memory, and then issue instructions based on the read data to cause the corresponding atomizer to generate aerosol.

[0114] In one embodiment, the operating member 2 is configured to be user-operable so that the user can customize the operating mode. For example, the user can use the operating member 2 to customize the aerosol volume ratio of the first aerosol, the second aerosol, and / or the third aerosol. For example, the user can use the operating member 2 to customize the total amount of aerosol generated.

[0115] In some embodiments, the operating element 2 includes a touch screen, a knob, a sliding switch, a button, a remote control, or a keyboard.

[0116] When the operating member 2 includes a button, the button may be one or more. For example, when there are multiple buttons, each button may correspond to a preset mode, so that when one of the buttons is triggered, the corresponding preset mode is selected. For example, when there is only one button, different preset modes can be selected by long pressing or short pressing the button, or the operating mode can be changed by continuously pressing the button.

[0117] In some embodiments, the operating member 2 includes a puff detection element, which is configured to detect the puff degree of the aerosol generating device 100 and establish a first operating mode at a first puff degree and a second operating mode at a second puff degree.

[0118] Specifically, the puff detection element may be provided with a variable capacitance sensing capacitor for sensing airflow or air pressure. The sensing capacitor has different capacitance corresponding to different puff levels. The controller can obtain the capacitance of the sensing capacitor or an electrical parameter associated with the capacitance, and can judge the puff level based on the size of the obtained capacitance or electrical parameter and / or the duration of a certain capacitance or electrical parameter, and then control the corresponding atomizer to generate an aerosol volume or an aerosol volume ratio that conforms to the current working mode.

[0119] The degree of puffing can include puff force, and the capacitance or electrical parameter of the sensing capacitor can be positively or negatively correlated with the puff force. Therefore, the aerosol generating device 100 can automatically change operating modes based on the user's puff force to meet the user's current needs. For example, when a user takes multiple puffs, the aerosol generating device 100 can provide the user with varying puff flavors and a different puff experience based on the user's puff force over the number of puffs.

[0120] The puff duration may include the duration of a puff. The duration of a certain capacitance or electrical parameter of the sensing capacitor may be positively or negatively correlated with the puff duration. The aerosol generating device 100 may switch operating modes when the duration of a user's puff reaches a preset duration, thereby providing the user with different top notes and after notes during a puff, thereby providing the user with a variety of puff flavors and a rich puff experience.

[0121] In some embodiments of the present application, the controller can respond to the operation of the operating member 2. Specifically, the controller can respond to the working mode set by the operating member 2 to control the atomizer associated with the working mode to generate an aerosol volume or an aerosol volume ratio that conforms to the working mode.

[0122] The controller can be configured to:

[0123] In response to the set working mode, obtaining one or more target atomizers associated with the current working mode;

[0124] Obtaining the electrical power required by each of the one or more target atomizers in a current operating mode;

[0125] The one or more target atomizers are controlled to operate with the electric power required by each in the current operating mode.

[0126] For example, the second preset mode specifies that the first aerosol accounts for 75% of the aerosol volume, the second aerosol accounts for 25% of the aerosol volume, and the third aerosol accounts for 0%. The second preset mode is selected as the current operating mode via operating element 2. The controller responds by reading data related to the second preset mode from memory. The controller then selects, from the plurality of aerosols, a first aerosol 1 for generating the first aerosol and a second aerosol 2 for generating the second aerosol as the two target aerosols, and a third aerosol 3 as the non-target aerosol.

[0127] The controller obtains the aerosol volume ratio of the first aerosol and the aerosol volume ratio of the second aerosol based on the data related to the second preset mode read from the memory.

[0128] Then, the controller controls the first atomizer 1 to operate at a first power, so that the first atomizer 1 generates a first aerosol volume that substantially satisfies the aerosol volume ratio of the first aerosol in the first preset mode; controls the second atomizer 2 to operate at a second power, so that the second atomizer 2 generates a second aerosol volume that substantially satisfies the aerosol volume ratio of the second aerosol in the first preset mode; and controls the third atomizer 3 to not operate.

[0129] In some embodiments, reference may be made to Figure 1 and Figure 2 The aerosol generating device 100 or the first atomizer 1 further includes a mouthpiece assembly 7 having an inhalation port 71. The aerosols generated by the multiple atomizers 1 can all flow into the inhalation port 71. At least a portion of the mouthpiece assembly 7 can be held by the user's mouth. When the user holds the mouthpiece assembly 7, the inhalation port 71 is positioned toward the user's oral cavity. The user inhales the aerosol output by the aerosol generating device 100 by inhaling the mouthpiece assembly 7.

[0130] In some embodiments, reference may be made to Figure 2 and Figure 3 The first atomizer 1 includes a first channel 13 and a second channel 14, which are independently in fluid communication with the nozzle assembly 7. Therefore, the airflow in the first channel 13 and the airflow in the second channel 14 may not intersect in the first atomizer 1 during their downstream flow.

[0131] The second atomizer 2 is in fluid communication with the first channel 13, so that at least part of the second aerosol can flow into the mouthpiece assembly 7 through the first channel 13. The third atomizer 3 is in fluid communication with the second channel 14, so that at least part of the third aerosol can flow into the mouthpiece assembly 7 through the second channel 14.

[0132] In some embodiments, the second nebulizer 2 and / or the third nebulizer 3 is configured to be sealedly connected to the first nebulizer 1 to prevent the second aerosol from flowing into the second channel 14 and to prevent the third aerosol from flowing into the first channel 13, or to prevent the second aerosol and the third aerosol from mixing with each other before flowing into the first nebulizer 1.

[0133] For example, you can refer to Figure 2 and Figure 6 The first atomizer 1 further includes a soft seat 15, which is provided with a first inlet 151 in fluid communication with the first channel 13 and a second inlet 152 in fluid communication with the second channel 14. The soft seat 15 elastically abuts against the second atomizer 2 and the third atomizer 3, establishing a sealed connection between the second atomizer 2 and the third atomizer 3 and the first atomizer 1. Thus, the second atomizer 2 is in sealed communication with the first channel 13, and the third atomizer 3 is in sealed communication with the second channel 14. The soft seat 15 can be made of silicone.

[0134] For further information, please refer to Figure 2 and Figure 6 The first atomizer 1 further includes a first shell 16, in which the first storage cavity is disposed. The soft seat 15 is sealingly connected to the first shell 16, so that the soft seat 15 can seal one end of the first storage cavity to prevent leakage of the first aerosol generating matrix.

[0135] It should be noted that other methods may be used to prevent the second aerosol and the third aerosol from mixing with each other before flowing into the first atomizer 1 .

[0136] In some embodiments, reference may be made to Figure 2 A mixing chamber 72 is provided inside the suction nozzle assembly 7 , and the mixing chamber 72 is fluidically connected to the suction port 71 . The mixing chamber 72 is fluidically connected to the first channel 13 and the second channel 14 .

[0137] When the second atomizer 2 and the third atomizer 3 generate aerosols simultaneously, the second aerosol and the third aerosol may be mixed in the mixing chamber 72 and then flow into the inlet 71 .

[0138] In some embodiments, the first atomizer assembly 11 is disposed corresponding to the first channel 13, such that the first aerosol generated by atomizing the first aerosol-generating substrate by the first atomizer assembly 11 is primarily directed to the mouthpiece assembly 7 via the first channel 13. When the first atomizer 1 and the second atomizer 2 simultaneously generate aerosol, the second aerosol and at least a portion of the first aerosol can mix in the first channel 13, thereby forming a first mixed aerosol.

[0139] When the first atomization assembly 11 includes a first heating element 112 and a second heating element 113, and the first heating element 112 and the second heating element 113 are electrically connected to the power supply assembly 5 independently and separately, the proportion of the first aerosol in the first mixed aerosol can be regulated by controlling the number of heating elements participating in heating in the first heating element 112 and the second heating element 113.

[0140] For example, in one operating mode, the first heating element 112, the second heating element 113, and the third heating element 212 are all working and generating heat. In another operating mode, the first heating element 112 and the third heating element 212 are all working and generating heat, while the second heating element 113 is not working and generating heat. Alternatively, in another operating mode, the second heating element 113 and the third heating element 212 are all working and generating heat, while the first heating element 112 is not working and generating heat.

[0141] When the second atomization assembly 21 includes a third heating element 212 and a fourth heating element 213, and when the third heating element 212 and the fourth heating element 213 are electrically connected to the power supply assembly 5 independently, the proportion of the second aerosol in the first mixed aerosol can be regulated by controlling the number of heating elements participating in heating in the third heating element 212 and the fourth heating element 213.

[0142] For example, the first atomizer assembly 11 does not include the second heating element 113. In one operating mode, the first heating element 112, the third heating element 212, and the fourth heating element 213 all operate and generate heat. In another operating mode, the first heating element 112 and the third heating element 212 all operate and generate heat, while the fourth heating element 213 does not. Alternatively, in another operating mode, the first heating element 112 and the fourth heating element 213 all operate and generate heat, while the third heating element 212 does not.

[0143] Or for example: the first atomizer assembly 11 has a second heating element 113 that works independently of the first heating element 112. In one operating mode, the first heating element 112, the second heating element 113, the third heating element 212, and the fourth heating element 213 all work and generate heat. In another operating mode, the first heating element 112 and the second heating element 113 both work and generate heat, one of the third heating element 212 and the fourth heating element 213 works and generates heat, and the other does not work and generates heat. Or in another operating mode, the third heating element 212 and the fourth heating element 213 both work and generate heat, one of the first heating element 112 and the second heating element 113 works and generates heat, and the other does not work and generates heat.

[0144] In other embodiments, the proportions of the first aerosol and the second aerosol in the first mixed aerosol can be adjusted by increasing or decreasing the electric power provided by the power supply to the first atomization assembly 11, or by increasing or decreasing the electric power provided by the power supply to the second atomization assembly 21.

[0145] In some embodiments, reference may be made to Figure 4 The first atomizer 1 further includes a fourth atomizer assembly 12, which is disposed corresponding to the second channel 14 such that the first aerosol generated by atomizing the first aerosol-generating substrate by the fourth atomizer assembly 12 is primarily directed to the mouthpiece assembly 7 via the second channel 14. When the first atomizer 1 and the third atomizer 3 simultaneously generate aerosols, the third aerosol and at least a portion of the first aerosol can mix in the second channel 14 to form a second mixed aerosol.

[0146] In some embodiments, the first atomizer 1 may have two independent first storage chambers, which are not connected to each other. Each first storage chamber is used to store the first aerosol generating matrix. The first atomization assembly 11 and the fourth atomization assembly 12 are respectively arranged corresponding to the two first storage chambers, so that the first atomization assembly 11 and the fourth atomization assembly 12 are respectively used to atomize the first aerosol generating matrix stored in different first storage chambers.

[0147] Alternatively, the first atomizer assembly 11 and the fourth atomizer assembly 12 are arranged corresponding to the same first storage cavity, so that the first atomizer assembly 11 and the fourth atomizer assembly 12 can atomize the first aerosol-generating substrate stored in the same first storage cavity.

[0148] In some embodiments, the first aerosol-generating substrate is a liquid substrate, and the fourth atomizing assembly 12 includes an ultrasonic element capable of high-frequency vibration under ultrasonic drive.

[0149] In some embodiments, the first aerosol-generating substrate is a liquid substrate, and the fourth atomizing assembly 12 includes a second liquid-absorbing element 121 and a seventh heating element 122. The seventh heating element 122 can be connected to or in contact with the second liquid-absorbing element 121. The second liquid-absorbing element 121 can be a porous body, which is used to guide the liquid substrate into the atomization range of the seventh heating element 122.

[0150] In some embodiments, the power supply assembly 5 is electrically connected to the seventh heating element 122 , and the controller can control the power output of the power supply to the seventh heating element 122 , thereby controlling the amount of the first aerosol generated by the first atomizer 1 per unit time.

[0151] In some embodiments, the fourth atomizer assembly 12 includes both a seventh heating element 122 and an eighth heating element 123. The seventh heating element 122 and the eighth heating element 123 can be connected to the same second liquid-absorbing element 121. Alternatively, the seventh heating element 122 and the eighth heating element 123 can be connected to two independent second liquid-absorbing elements 121.

[0152] The seventh heating element 122 and the eighth heating element 123 can be arranged along the direction in which the second channel 14 in the first atomizer 1 extends, or can be arranged along the direction of the airflow in the first atomizer 1 during inhalation, or can be arranged along the extension direction of the second liquid-absorbing element 121. This allows the fourth atomizer assembly 12 to have a larger atomization area when the seventh heating element 122 and the eighth heating element 123 are operating simultaneously, thereby increasing the amount of the first aerosol produced per unit time.

[0153] In some embodiments, the first atomizer 1 includes a positive electrode and a negative electrode, and the positive electrode and negative electrode of the first atomizer 1 are respectively used to electrically connect to the positive electrode and negative electrode of the power supply. The seventh heating element 122 and the eighth heating element 123 can be connected in parallel with each other between the positive electrode and the negative electrode.

[0154] In some embodiments, the power supply assembly 5 is configured to independently provide electrical power to the seventh heating element 122 and the eighth heating element 123 , so that the seventh heating element 122 and the eighth heating element 123 can operate independently and be controlled independently.

[0155] The seventh heating element 122 and the eighth heating element 123 may have substantially the same resistance material and the same initial resistance, may have substantially the same shape structure, and may have substantially the same size.

[0156] The seventh heating element 122 and the first heating element 112 may have substantially the same resistance material and the same initial resistance; the seventh heating element 122 and the first heating element 112 may have substantially the same shape and structure; the seventh heating element 122 and the first heating element 112 may have substantially the same size.

[0157] When the fourth atomizer assembly 12 includes a seventh heating element 122 and an eighth heating element 123, and when the seventh heating element 122 and the eighth heating element 123 are electrically connected to the power supply assembly 7 independently, the proportion of the first aerosol in the second mixed aerosol can be regulated by controlling the number of heating elements participating in heating in the seventh heating element 122 and the eighth heating element 123.

[0158] When the third atomization assembly 31 includes a fifth heating element 312 and a sixth heating element 313, and when the fifth heating element 312 and the sixth heating element 313 are electrically connected to the power supply assembly 5 independently, the proportion of the third aerosol in the second mixed aerosol can be regulated by controlling the number of heating elements participating in heating in the fifth heating element 312 and the sixth heating element 313.

[0159] In some embodiments, the power supply assembly 5 is configured to independently provide electrical power to the first atomizer assembly 11 and the fourth atomizer assembly 12. Thus, the first atomizer assembly 11 and the fourth atomizer assembly 12 can operate simultaneously or independently. Alternatively, the first atomizer assembly 11 and the fourth atomizer assembly 12 can use the same electrical power to atomize the first aerosol-generating substrate, or they can use different electrical powers to atomize the first aerosol-generating substrate.

[0160] The proportion of the first aerosol in the total aerosol can be adjusted by controlling the number of atomizer assemblies participating in the first atomizer assembly 11 and the fourth atomizer assembly 12 .

[0161] As an example, when the first atomizer assembly 11, the second atomizer 2, and the third atomizer 3 are in operation and the fourth atomizer assembly 12 is not in operation, the first aerosol formed by atomizing the first aerosol generating substrate by the first atomizer assembly 11 mixes with the second aerosol in the first channel 13 to form a first mixed aerosol, and then the first mixed aerosol flows into the mixing chamber 72. The third aerosol flows into the mixing chamber 72 through the second channel 14, and thus the third aerosol mixes with the first mixed aerosol in the mixing chamber 72.

[0162] As an example, when the fourth atomizer assembly 12, the second atomizer 2, and the third atomizer 3 are in operation and the first atomizer assembly 11 is not in operation, the first aerosol formed by atomizing the first aerosol generating substrate by the fourth atomizer assembly 12 is mixed with the third aerosol in the second channel 14 to form a second mixed aerosol, and then the second mixed aerosol flows into the mixing chamber 72. The second aerosol flows into the mixing chamber 72 through the first channel 13, and the second aerosol is mixed with the second mixed aerosol in the mixing chamber 72.

[0163] As an example, the first atomizing assembly 11, the fourth atomizing assembly 12, the second atomizer 2, and the third atomizer 3 operate to form a first mixed aerosol in the first channel 13 and a second mixed aerosol in the second channel 14. The first mixed aerosol and the second mixed aerosol are then mixed in the mixing chamber 72.

[0164] As an example, the first atomizer 1 is not working, and the second atomizer 2 and the third atomizer 3 are working, then the second aerosol and the third aerosol are mixed in the mixing chamber 72 to form a mixed aerosol that does not contain the first aerosol.

[0165] When the second aerosol-generating substrate and the third aerosol-generating substrate are the same, or when the second aerosol and the third aerosol have the same flavor, the total aerosol volume and / or the proportion of the first aerosol in the total aerosol volume can be regulated by controlling the number of atomizers participating in the second atomizer 2 and the third atomizer 3.

[0166] In some embodiments, reference may be made to Figure 2 The second atomizer 2 further includes a third channel 22. The second atomizing assembly 21 is arranged corresponding to the third channel 22, so that the second aerosol is mainly guided from the third channel 22 to the first channel 13. The third channel 22 and the first channel 13 can be arranged coaxially.

[0167] In some embodiments, reference may be made to Figure 2 The third atomizer 3 further includes a fourth channel 32. The third atomizing assembly 31 is arranged corresponding to the fourth channel 32, so that the third aerosol is mainly guided from the fourth channel 32 to the second channel 14. The fourth channel 32 and the second channel 14 can be arranged coaxially.

[0168] In some embodiments, reference may be made to Figure 1 and Figure 2 The aerosol generating device 100 further comprises a housing 8, in which at least a portion of the first atomizer 1, the second atomizer 2 and the third atomizer 3 can be disposed. The housing 8 helps to increase the surface consistency of the aerosol generating device 100.

[0169] Furthermore, at least a portion of the first atomizer 1 and at least one of the second atomizer 2 and the third atomizer 3 are removably disposed in the housing 8 , so that at least one of the first atomizer 1 , the second atomizer 2 and the third atomizer 3 can be replaced.

[0170] In some embodiments, the aerosol generating device 100 further includes a first conductive element electrically connected to the first atomizer 1, and the first conductive element passes through the second atomizer 2 and is electrically connected to the power supply assembly 5. On the one hand, this can reduce the distance between the first atomizer 1 and the second atomizer 2 and / or the distance between the first atomizer 1 and the third atomizer 3, thereby shortening the length of the air path between the first atomizer 1 and the second atomizer 2 and / or the distance between the first atomizer 1 and the third atomizer 3, thereby reducing the amount of condensation of the second aerosol before entering the first channel 13 and / or the amount of condensation of the third aerosol before entering the second channel 14. On the other hand, this can prevent the first conductive element from affecting the sealing connection between the first atomizer 1 and the second atomizer 2 and / or the distance between the first atomizer 1 and the third atomizer 3, thereby preventing the second aerosol from leaking before entering the first channel 13 and / or preventing the third aerosol from leaking before entering the second channel 14.

[0171] The first conductive element may be a wire, a conductive metal, or a flexible circuit board.

[0172] For further information, please refer to Figure 3 The second atomizer 2 is provided with a first through-hole 23 for the first conductive element to pass through. The aerosol generating device 100 further includes a sealant disposed in the first through-hole 23 to seal the gap between the first atomizer 1 and the first conductive element. This prevents leakage of the first aerosol and / or second aerosol through the first through-hole. After the first conductive element passes through the first through-hole 23, a sealant can be injected into the first through-hole 23 to fill the first through-hole 23. The sealant cures to form a sealant.

[0173] The first conductive element can pass through the second storage cavity. The first through hole 23 passes through the liquid storage cotton 4 in the second atomizer 2.

[0174] The first through hole 23 may be parallel to the third channel 22 .

[0175] In some embodiments, the aerosol generating device 100 further includes a second conductive element electrically connected to the first atomizer 1 , and the second conductive element is electrically connected to the power supply assembly 5 through the third atomizer 3 .

[0176] The second conductive element may be a wire, a conductive metal, or a flexible circuit board.

[0177] For further information, please refer to Figure 3The third atomizer 3 is provided with a second through-hole 33 for the second conductive element to pass through. The aerosol generating device 100 further includes a sealant disposed in the second through-hole 33 to seal the gap between the first atomizer 1 and the second conductive element. This prevents leakage of the first aerosol and / or second aerosol through the second through-hole. After the second conductive element passes through the second through-hole, a sealant can be injected into the second through-hole 33 to fill the second through-hole 33. The sealant cures to form a sealant.

[0178] The second conductive element can pass through the third storage chamber 32. The second through hole 33 passes through the liquid storage cotton 4 in the third atomizer 3.

[0179] The second through hole 33 may be parallel to the four channels 32 .

[0180] The first conductive element can be electrically connected to the first atomization assembly 11 , and the second conductive element can be electrically connected to the fourth atomization assembly 12 .

[0181] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 further includes an air regulating switch 9 , which is configured to adjust the air intake volume of the air intake channel 10 .

[0182] The air regulating switch 9 may include a manual air regulating switch, and the user may directly operate the air regulating switch 9 to adjust the air intake volume of the air intake channel 10 , thereby adjusting the concentration of the aerosol or the inhalation resistance inhaled by the user through the inhalation port 71 .

[0183] The air regulating switch 9 may include an electrically controlled air regulating switch, which is electrically connected to the controller so as to be controlled by the controller to adjust the air intake amount of the air intake passage 10 .

[0184] The air regulating switch 9 may include a continuous air regulating switch, which can continuously adjust the air intake volume of the air intake passage 10 , and can make the air intake volume of the air intake passage 10 gradually change from small to large or from large to small.

[0185] The air regulating switch 9 may include a gear-type air regulating switch, and different air intake gears can cause the air intake amount of the air intake passage 10 to change suddenly.

[0186] It should be noted that the specification and drawings of this application provide preferred embodiments of the present application, but are not limited to the embodiments described in this specification. Furthermore, it is possible for a person skilled in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
