DETAILED DESCRIPTION

[0043] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0044] In the embodiment of the present application, the orientation or position relationship of "upper", "lower", "top" and "bottom" is based on the attached Figure 1 The orientation or position relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] On the one hand, the present application provides an aerosol generating device. Figure 2 and Figure 3 , including a accommodating chamber 20a and an air supply assembly 10.

[0046] The aerosol generating device 100 is used to atomize an atomizing medium to generate an aerosol for the user to inhale. The atomizing medium includes but is not limited to medicines, nicotine-containing materials or solid materials without nicotine, etc.

[0047] The atomizing medium may be a solid material with plants such as tobacco as the main raw material and corresponding aerosol formers and aroma materials added thereto. In one embodiment, the atomizing medium may be cylindrical.

[0048] The aerosol generating device 100 generally also includes a heating element and a power supply component. The heating element is electrically connected to the power supply component. The power supply component provides electrical energy to the heating element. The heating element can convert the electrical energy into thermal energy. The atomizing medium is atomized under the action of the heating element to generate an aerosol.

[0049] It should be noted that the appearance of the heating element is not limited. In some embodiments, the heating element is a heating needle with a needle-like structure, and the heating needle can be inserted into the atomizing medium to heat and atomize the atomizing medium.

[0050] In some other embodiments, the heating element may also be a heating sheet having a tip for inserting the atomized medium.

[0051] The accommodating chamber 20a is used to accommodate the atomizing medium, and the atomizing medium can be atomized in the accommodating chamber 20a to generate aerosol.

[0052] It is understandable that the aerosol generating device 100 is also provided with an opening communicating with the accommodating chamber 20a, and the atomized medium can be placed into or removed from the accommodating chamber 20a through the opening.

[0053] The shape of the accommodating cavity 20a is not limited. For example, see Figure 2 and Figure 3 The accommodating chamber 20a may be cylindrical, and the peripheral side wall of the cylindrical accommodating chamber 20a is circular, so that the atomized medium can be conveniently placed in or removed from the accommodating chamber 20a.

[0054] The air supply assembly 10 is provided with an air supply channel 11a, and the accommodating chamber 20a is connected with the outside through the air supply channel 11a. The air supply assembly 10 is used to transport the outside airflow to the accommodating chamber 20a through the air supply channel 11a.

[0055] It should be noted that the atomizing medium easily absorbs water vapor in the ambient air, resulting in a higher water vapor content in the atomizing medium. The water vapor retained in the atomizing medium, on the one hand, causes the heat of the aerosol generating device 100 to be absorbed by moisture, thereby increasing the power required for the atomizing medium to be atomized into an aerosol; on the other hand, the high-temperature water vapor easily causes the first two puffs of aerosol to burn the mouth.

[0056] It can be understood that after the external airflow enters the containing chamber 20a, it can take away the water vapor retained on the atomizing medium and leave the containing chamber 20a, thereby being able to reduce the water vapor content in the atomizing medium to a certain extent. In this way, during use by the user, on the one hand, the heat generated by the aerosol generating device 100 can be used more for heating the atomizing medium, and the power required for atomizing the atomizing medium to produce aerosol is lower; on the other hand, it can reduce the content of high-temperature water vapor carried by the aerosol, thereby reducing the temperature of the aerosol, and can reduce the risk of scalding the mouth in the first two puffs of aerosol.

[0057] Furthermore, the structure of the air supply assembly 10 is relatively simple and compact, so that the volume of the aerosol generating device 100 can be designed to be more compact.

[0058] In the related art, the packaging box of the atomizing medium is sealed to prevent moisture from exceedingly high water vapor content in the atomizing medium. However, when the user opens the package and the atomizing medium is exposed to a high humidity environment, the effect of this measure will be significantly weakened, and the provision of a cooling structure in the atomizing medium leads to problems such as complex production process, increased cost, waste of resources, and poor cooling in a high humidity environment. Some aerosol generating devices are designed with a condensation air duct to absorb the high-temperature water vapor in the atomizing medium, which makes the aerosol generating device large in size and complex in structure, and the condensation water absorbing consumables need to be replaced frequently, resulting in inconvenience in use and increased cost.

[0059] In the aerosol generating device 100 of the embodiment of the present application, the accommodating chamber 20a is used to accommodate the atomizing medium, and the air supply component 10 is provided with an air supply channel 11a. The accommodating chamber 20a is connected with the outside through the air supply channel 11a. The air supply component 10 is used to transport the external airflow to the accommodating chamber 20a through the air supply channel 11a, and introduce the external airflow into the accommodating chamber 20a through the air supply component 10, so as to take away the water vapor in the atomizing medium and reduce the water vapor content in the atomizing medium. That is to say, the aerosol generating device 100 of the embodiment of the present application can take away the water vapor in the atomizing medium, thereby reducing the content of water vapor in the atomizing medium. When the user inhales, the content of high-temperature water vapor is relatively low, which reduces the risk of scalding the mouth. At the same time, the moisture-proof requirements of the atomizing medium can be reduced, which facilitates the production of the atomizing medium and reduces the production cost and mass production process complexity of the atomizing medium. On the other hand, the air supply component 10, as a dehydration component of the aerosol generating device 100, does not generate consumables, and the user's use cost is relatively low. At the same time, the air supply component 10 can work in a cycle, eliminating the user's operation of replacing the dehydration component, which is convenient for user use.

[0060] In one embodiment, please refer to Figures 1 to 3 The aerosol generating device 100 includes a shell 40, which is an appearance structural component of the aerosol generating device 100. An installation space 40a can be opened on the shell 40, and components such as the air supply component 10 of the aerosol generating device 100 can be arranged in the installation space 40a.

[0061] The formation method of the accommodation cavity 20a is not limited. For example, please refer to Figure 2 and Figure 3 In one embodiment, the aerosol generating device 100 includes a heating tube 20, and the heating tube 20 is the heating element mentioned above.

[0062] The heating tube 20 forms a receiving cavity 20 a. After the atomized medium is placed in the receiving cavity 20 a, the heating tube 20 wraps around the atomized medium.

[0063] It is understandable that water vapor in the air can more easily enter the interior of the atomizing medium through the peripheral side of the atomizing medium. Generally speaking, the water vapor content on the peripheral side of the atomizing medium is relatively high.

[0064] After the heating tube 20 generates heat, the heat can be preferentially transferred to the surrounding side of the atomizing medium. In this way, in the preheating stage, the heat generated by the heating tube 20 can be transferred to the water vapor as much as possible, thereby increasing the temperature of the water vapor. The high-temperature and high-humidity water vapor can be fully carried away from the accommodating chamber 20a by the external airflow introduced by the air supply component 10, and the aerosol generating device 100 has a better dehydration effect.

[0065] It should be noted that the preheating stage refers to the stage in which the heat generated by the aerosol generating device 100 is used to heat the atomizing medium to increase its temperature, and the water vapor absorbs the heat and becomes a high temperature and high humidity state, so that the water vapor is more easily absorbed by the external airflow.

[0066] During the preheating stage, the temperature in the accommodating chamber 20a is lower than the atomization temperature of the atomizing medium (generally between 200°C and 350°C), thereby reducing the waste of the atomizing medium.

[0067] The extending direction of the heating tube 20 is not limited. Figures 1 to 3 The extending directions of the axial ends of the heating tube 20 can be used as the top and bottom directions of the aerosol generating device 100 , and the atomized medium can be placed into the accommodating cavity 20 a from the top of the aerosol generating device 100 .

[0068] The air supply channel 11a may be formed in any manner. In some embodiments, the air supply channel 11a may be formed integrally on the housing 40 .

[0069] In some other embodiments, please refer to Figure 2 and Figure 3 The air supply assembly 10 includes a base 11, which is provided with an air supply channel 11a and a flow port 11b, and the air supply channel 11a is connected to the accommodating chamber 20a through the flow port 11b. That is, the external air flow can enter the accommodating chamber 20a through the air supply channel 11a and the flow port 11b in sequence.

[0070] The position of the flow port 11b on the seat body 11 is not limited. For example, please refer to Figure 1 , Figure 4 and Figure 5 , the flow port 11 b is located at the top of the base body 11 . That is, the heating pipe 20 formed with the accommodating cavity 20 a can be disposed at the top of the base body 11 .

[0071] The seat body 11 can facilitate the opening of the air supply channel 11a in the aerosol generating device 100. Specifically, the seat body 11 can be a component of the aerosol generating device 100, and can be processed separately. On the one hand, the seat body 11 can be processed to form air supply channels 11a of different shapes according to actual needs. On the other hand, the seat body 11 can be installed in the housing 40 after being processed. In this way, the seat body 11 and the housing 40 can be processed at the same time, thereby improving the production efficiency of the aerosol generating device 100.

[0072] It can be understood that, in this embodiment, the structure of the housing 40 is relatively simple and easy to produce.

[0073] The position of the base 11 on the aerosol generating device 100 is not limited. Figure 2 and Figure 3 The seat body 11 may be at the bottom of the heating tube 20 . The seat body 11 provides an installation base for the heating tube 20 . The heating tube 20 may be installed on the seat body 11 . External air flows through the bottom of the heating tube 20 to the top.

[0074] The shape of the air supply channel 11a is not limited. For example, see Figure 4 and Figure 5 , can be an "L"-shaped air supply channel 11a of this shape. After the base 11 is connected to the heating tube 20, the accommodating cavity 20a and the air supply channel 11a can also form an "L"-shaped cavity. In this way, the size of the aerosol generating device 100 in a certain direction can be reduced, thereby facilitating the design of the overall appearance, size, etc. of the aerosol generating device 100.

[0075] See also Figures 2 to 5 The air supply assembly 10 further includes a fan blade 12, which is disposed in the air supply channel 11a. Thus, the flow of air in the air supply channel 11a can be enhanced, thereby transporting external airflow to the accommodating chamber 20a through the air supply channel 11a.

[0076] The movement form of the fan blade 12 is not limited, for example, it can be rotation, reciprocating motion, etc.

[0077] It should be noted that there is no limitation on the method of controlling the fan blades 12 to convey the external airflow.

[0078] In some embodiments, a rocker (not shown) is provided to connect with the fan blade 12, and the user controls the rotation of the fan blade 12 through the rocker, thereby delivering the external airflow into the accommodating chamber 20a. The rotation of the fan blade 12 is controlled manually, and the structure of the aerosol generating device 100 is relatively simple, and the production cost is relatively low.

[0079] In some other embodiments, please refer to Figure 4 and Figure 5The air supply assembly 10 includes a driving member 13 , which is drivingly connected to the fan blade 12 .

[0080] The type of the driving element 13 is not limited, and it may be, for example, a motor, a solenoid valve, a gear pump, or a piston pump.

[0081] The power supply assembly can provide electrical energy to the driving member 13, and the driving member 13 converts the electrical energy into mechanical energy and outputs it to the fan blades 12. The fan blades 12 deliver the external airflow to the accommodating chamber 20a through the air supply channel 11a.

[0082] Specifically, see Figure 2 , Figure 3 and Figure 5 The driving member 13 is provided with a rotating shaft 131, and the rotating shaft 131 is drivingly connected to the fan blade 12. When it is necessary to transport the external airflow to the accommodating chamber 20a, the power supply component provides power to the driving member 13. When the driving member 13 is energized, the rotating shaft 131 rotates to drive the fan blade 12 to rotate, thereby blowing the airflow toward the accommodating chamber 20a.

[0083] In this embodiment, the fan blades 12 are controlled by the driving member 13 to convey the external airflow, and the aerosol generating device 100 has a high degree of automation and is convenient for users to use.

[0084] The installation method of the driving member 13 is not limited. For example, in one embodiment, refer to Figure 5 The seat body 11 is provided with a mounting groove 11c and a partition wall 11d between the mounting groove 11c and the air supply channel 11a, the partition wall 11d is formed with a through hole 11e, the driving member 13 is provided in the mounting groove 11c, and the rotating shaft 131 of the driving member 13 extends into the air supply channel 11a through the hole 11e and is drivingly connected with the fan blade 12. The mounting groove 11c can facilitate the installation of the driving member 13, and the through hole 11e can facilitate the rotating shaft 131 of the driving member 13 to extend into the air supply channel 11a.

[0085] It is understandable that the rotating shaft 131 of the driving member 13 generally needs to be coaxially arranged with the fan blade 12, and the airflow also enters the fan blade 12 through the axial direction of the fan blade 12. In other words, the axial direction of the driving member 13 needs to be parallel to the axial direction of a part of the air supply channel 11a.

[0086] For details, please continue to see Figure 5 The "L"-shaped air supply channel 11a is formed with a corner, so that the main structure of the driving member 13 is conveniently arranged outside the air supply channel 11a. The fan blades 12 can be driven to move by only extending the rotating shaft 131 into the air supply channel 11a through the hole 11e. The driving member 13 generates less resistance to the airflow, and the air supply assembly 10 has a better water removal effect.

[0087] The type of the fan blade 12 is not limited, for example, it can be an axial flow fan blade 12, a centrifugal fan blade 12, etc.

[0088] See also Figure 2 The airflow of the axial flow fan blade 12 flows along the axial direction of the fan blade 12. When the air supply channel 11a is designed to be in the above-mentioned "L" shape, the axial flow fan blade 12 can be set as far away from the corner of the air supply channel 11a as possible. In this way, the airflow passes through the fan blade 12, passes through one end distance, and then passes through the corner, which can reduce the resistance of the corner to the airflow, and can improve the water removal effect of the air supply component 10 to a certain extent.

[0089] In one embodiment, please refer to Figure 3 , Figure 5 and Figure 6 The fan blade 12 includes a wheel disc 12a, a rotating shaft 12b and a plurality of blades 12c surrounding the rotating shaft 12b. One end of the rotating shaft 12b and each blade 12c are connected to the wheel disc 12a, and the other ends extend in a direction away from the wheel disc 12a.

[0090] It can be understood that, in this embodiment, the fan blade 12 is a centrifugal fan blade 12. The rotating shaft 131 of the driving member 13 is drivingly connected to the rotating shaft 12b. When the rotating shaft 131 rotates, the blade 12c is driven to rotate around the rotating shaft 12b. The fan blade 12 of this structure can introduce the external airflow along the axial direction of the fan blade 12 and discharge it in the radial direction of the fan blade 12. In this way, the flow direction of the airflow can be changed through the fan blade 12, which is convenient for the design of the air supply channel 11a.

[0091] For example, see Figure 5 As mentioned above, when the air supply channel 11a is set to an "L" shape, the fan blades 12 of this embodiment can be set at the corners of the air supply channel 11a, and the external airflow can be directly blown to the accommodating cavity 20a after passing through the fan blades 12. In this way, the resistance of the air supply channel 11a to the airflow is reduced, and the water removal effect of the air supply component 10 is better.

[0092] In one embodiment, please refer to Figure 5 The air supply assembly 10 includes a rectifying member 14 , the air supply channel 11 a includes an air inlet communicating with the outside, and the rectifying member 14 is disposed between the air inlet and the fan blades 12 .

[0093] The rectifying member 14 has a center hole extending axially. The rectifying member 14 is arranged in the air supply channel 11a. The extension direction of the center hole of the rectifying member 14 can be consistent with the extension direction of the air supply channel 11a. In this way, when the fan blade 12 is a centrifugal fan blade 12, the rectifying member 14 can allow the airflow to enter the center of the centrifugal fan blade 12 and prevent the boosted airflow from overflowing from all sides.

[0094] In one embodiment, please refer to Figures 1 to 3The housing 40 is provided with an opening 40b and an air inlet grille 40c located at the opening 40b, and the external air flow enters the air supply channel 11a through the air inlet grille 40c.

[0095] The air inlet grille 40c has a certain filtering effect, which can prevent larger impurities from entering the air supply channel 11a and affecting the movement of the fan blades 12. In this way, the risk of the fan blades 12 getting stuck can be reduced, and the reliability of the operation of the air supply assembly 10 is improved.

[0096] The air inlet grille 40c may be formed integrally on the outer shell 40. The outer shell 40 may be formed synchronously to form the air inlet grille 40c during the production process, and the processing may be completed on the same production line.

[0097] Of course, the air inlet grille 40c can also be a separate component. During the assembly process of the aerosol generating device 100, the air inlet grille 40c is assembled to the opening 40b of the outer shell 40. The air inlet grille 40c and the outer shell 40 can be processed on two production lines respectively, thereby improving the production efficiency of the aerosol generating device 100.

[0098] In this embodiment, the air inlet grille 40c and the housing 40 are assembled in any manner. For example, the air inlet grille 40c and the housing 40 may be connected by a non-detachable connection such as welding, so that the connection strength between the air inlet grille 40c and the housing 40 is higher and the stability is better.

[0099] Of course, the air inlet grille 40c can also be connected by a detachable connection method such as fastening connection, snap connection, etc. In this way, when a large amount of impurities enter the air supply channel 11a, the air inlet grille 40c can be removed from the outer shell 40, which is convenient for the user to clean the air supply channel 11a, and the service life of the aerosol generating device 100 is longer.

[0100] In one embodiment, please refer to Figure 2 and Figure 3 The aerosol generating device 100 includes a blocking member 30, which is used to block foreign matter in the accommodating chamber 20a from entering the air supply channel 11a.

[0101] It is understandable that when the air supply assembly 10 includes the fan blade 12, foreign matter entering the air supply passage 11a may affect the movement of the fan blade 12, thereby causing the fan blade 12 to fail. In this embodiment, the blocking member 30 can reduce the risk of foreign matter entering the air supply passage 11a, and the reliability of the operation of the air supply assembly 10 is relatively higher.

[0102] Specifically, the barrier 30 can be arranged at the bottom of the heating tube 20, and impurities dropped on the atomized medium can be blocked by the barrier 30. At the same time, the atomized medium can also be placed on the barrier 30 by its own gravity, and the barrier 30 can play the function of supporting the atomized medium.

[0103] In one embodiment, the aerosol generating device 100 further includes a control module, and the control module is used to control the implementation of various functions of the aerosol generating device 100 .

[0104] The control module includes a controller, which can receive instructions from a user and control the actions of various functional units of the aerosol generating device 100 .

[0105] It should be noted that the functional unit can be selected according to actual needs. For example, see Figure 7 In addition to the air supply component 10, the power supply component and the heating element, the functional unit may also include at least one of a switch unit, a timing unit and a signal output unit.

[0106] The switch unit is used to turn on or off the aerosol generating device 100. The user can transmit the on or off command to the controller through the switch unit, and the controller controls the actions of the heating element, the air supply component 10, the power supply component, the signal output unit, and the timing unit according to the received command.

[0107] The type of the switch unit is not limited. For example, the switch unit can be a button type, a touch type, etc.

[0108] The timing unit can accumulate time and feed back the accumulated time to the controller.

[0109] The type of the timing unit is not limited, for example, it can be a timer, a counter or a crystal oscillator.

[0110] The signal output unit can feed back the current state of the aerosol generating device 100 to the user, so that the user can identify the current state of the aerosol generating device 100 .

[0111] The type of the signal output unit is not limited, for example, it can be a vibrator, a signal light, etc.

[0112] Another aspect of the present application embodiment provides a control method of the aerosol generating device 100, which is used for the aerosol generating device 100 of any embodiment of the present application, see Figure 8 , control methods include:

[0113] Step S100: turning on the aerosol generating device;

[0114] Specifically, the user may transmit a power-on instruction to the controller of the aerosol generating device 100 through the switch unit, and after receiving the power-on instruction, the controller controls the aerosol generating device 100 to power on.

[0115] It is understandable that after the switch unit receives the user's instruction, the signal output unit can output a signal to prompt the user, so that the user can know that the aerosol generating device 100 has successfully received the corresponding instruction.

[0116] Specifically, taking the example of a signal output unit including a signal light and a vibrator, after the aerosol generating device 100 receives a command from the user, the vibrator can vibrate and the signal light can flash at the same time, and both the signal light and the vibrator can output signals. In this way, the signal light and the vibrator protect each other, thereby improving the reliability of the signal output unit.

[0117] It should be noted that the vibration frequency of the vibrator and the flashing frequency of the signal light are not limited and can be designed according to actual conditions. For example, the vibrator can vibrate once and the signal light can flash once.

[0118] Step S200: controlling the air supply component to deliver air to the accommodating chamber;

[0119] Specifically, the air supply component 10 may include a driving component 13 and a fan blade 12. When the aerosol generating device 100 is in the turned-on state, the controller can also control the power supply component to supply power to the driving component 13, and the driving component 13 drives the fan blade 12 to rotate, thereby delivering air to the accommodating chamber 20a.

[0120] Step S300: determining that the aerosol generating device is in an inhalable state;

[0121] It should be noted that the inhalable state of the aerosol generating device 100 means that the aerosol generated by the aerosol generating device 100 at this time will not burn the mouth.

[0122] Step S400: controlling the aerosol generating device to emit an inhalable signal.

[0123] It can be understood that, in this embodiment, the controller can determine that the aerosol generating device 100 is in the inhalable state. At the same time, the controller controls the signal output unit to send an inhalable signal, which is easy for users to identify and more convenient for users to use.

[0124] The types of signal output units and the methods of sending signals have been introduced above and will not be repeated here.

[0125] It is understandable that when the aerosol generating device 100 is in different states, the signal output unit may use different frequencies to send signals, so as to facilitate user differentiation. For example, when the aerosol generating device 100 is in the inhalable state, the vibrator may vibrate continuously for multiple times, and the signal light may flash in the form of a breathing light.

[0126] In this embodiment, after the aerosol generating device 100 is turned on, air is introduced into the accommodating chamber 20a through the air supply component 10, so that the water vapor retained in the atomized medium can be taken away, reducing the water content of the atomized medium. After the aerosol generating device 100 sends an inhalable signal, the user can start to inhale the aerosol. At this time, the concentration of high-temperature water vapor is relatively low, the concentration of the aerosol is higher, and the risk of aerosol burning the mouth is reduced.

[0127] It should be noted that there is no limit to the way to determine whether the aerosol generating device 100 is in an inhalable state. In some embodiments, the control module of the aerosol generating device 100 further includes a temperature detection unit, which can detect the temperature of the aerosol in real time and feed the temperature back to the controller. In this way, a preset temperature value that will not burn the mouth can be set. When it is detected that the temperature of the aerosol is lower than the preset temperature value, the controller can determine that the aerosol generating device 100 is in an inhalable state.

[0128] The type of the temperature detection unit is not limited, and can be, for example, a thermistor sensor, a temperature sensor, or the like.

[0129] In some other embodiments, the step of determining that the aerosol generating device 100 is in the inhalable state includes:

[0130] Step S310: obtaining the continuous working time of the air supply component 10;

[0131] Step S320: It is determined that the continuous working time reaches the second set time, and the aerosol generating device 100 is in an inhalable state.

[0132] Specifically, the continuous working time of the air supply component 10 can be recorded by a timing unit. When the controller controls the power supply component to supply power to the air supply component 10, the controller can control the timing unit to start timing. The time accumulated by the timing unit at this stage is the continuous working time of the air supply component 10. The timing unit can feed back the continuous working time of the air supply component 10 to the controller in real time. After the controller confirms that the continuous working time of the air supply component 10 reaches the second set time, it can be determined that the aerosol generating device 100 is in an inhalable state.

[0133] It should be noted that the value of the second set time is not limited and can be designed according to the flow rate of the air flow delivered by the air supply component 10, and the specific value can be obtained through testing before leaving the factory.

[0134] Exemplarily, the second set time may be set within a range of 5 seconds to 8 seconds, such as 5 seconds, 6 seconds, 7 seconds, 8 seconds, etc.

[0135] After the continuous working time of the air supply component 10 reaches the second set time, it can be understood that the water vapor content in the atomized medium will not cause the risk of scalding the mouth. The controller can control the power supply component to stop supplying power to the air supply component 10, and the air supply component 10 stops working. In this way, the power of the power supply component can be saved.

[0136] When the air supply assembly 10 stops working, the controller can also synchronously control the timing unit to reset the accumulated time to zero, so that the time can be accumulated again when it is used next time.

[0137] It is understandable that when the air supply component 10 just stops working, the temperature in the accommodating chamber 20a is still relatively low. At this time, the heating element can continue to heat for a certain period of time, and then the aerosol generating device 100 can be controlled to send an inhalable signal, so that the user can inhale the aerosol when inhaling.

[0138] In one embodiment, before the step of controlling the air supply assembly 10 to supply air to the accommodating chamber 20a, the method further includes:

[0139] Controlling the heating element of the aerosol generating device 100 to generate heat;

[0140] Specifically, after the aerosol generating device 100 receives the power-on command, the power supply component supplies power to the heating element, and the heating element converts the electrical energy into thermal energy, thereby heating the atomizing medium. At the same time, the water vapor in the atomizing medium can also absorb heat and heat up.

[0141] Determine whether the air supply assembly 10 meets the start-up conditions.

[0142] After the air supply component 10 meets the starting conditions, the controller controls the air supply component 10 to turn on. In this way, the efficiency of the air supply component 10 during continuous working time can be improved. While ensuring the dehydration effect, the continuous working time of the air supply component 10 can be reduced, the loss of the air supply component 10 can be delayed, and the power of the power supply component can be saved.

[0143] It should be noted that the start-up condition of the air supply component 10 is not limited. Exemplarily, the start-up condition is that the continuous heating time of the heating element reaches a first set time.

[0144] Specifically, the timing unit can accumulate the continuous heating time of the heating element and feed back the accumulated time to the controller in real time. After the controller confirms that the continuous heating time of the heating element reaches the first set time, it controls the power supply component to supply power to the air supply component 10, and the air supply component 10 starts working.

[0145] It is understandable that when the continuous heating time of the heating element reaches the first set time, the timing unit can be reset to zero, so that the timing unit can continue to accumulate the continuous working time of the air supply component 10.

[0146] After the continuous heating time of the heating element reaches the first set time, the temperature of the atomized medium in the accommodating chamber 20a can reach a temperature that is relatively easy to be absorbed by the airflow, and illustratively, this temperature is about 50°C. Water vapor is easily separated from the atomized medium at this temperature. At this time, the air supply component 10 is controlled to be turned on. The overall water removal efficiency of the air supply component 10 is higher during the working time. When the heating element works within the first set time, the air supply component 10 does not need to be turned on, so that the power of the power supply component can be saved.

[0147] The value of the first set time is not limited and can be designed according to the heat generated by the heating element. The aerosol generating device 100 can confirm the specific value of the first set time through factory testing.

[0148] Exemplarily, the first set time may be a value within a range of 5 seconds to 12 seconds, for example, 5 seconds, 7 seconds, 9 seconds, 11 seconds, 12 seconds, etc.

[0149] In one embodiment, the aerosol generating device 100 is controlled to emit an inhalable signal, which may be:

[0150] Controlling the vibration of the vibrator of the aerosol generating device 100;

[0151] When the aerosol generating device 100 is in the inhalable state, the controller controls the vibrator to vibrate at a certain frequency or vibrate once, so that a signal can be transmitted to the user.

[0152] The vibrator can generate a vibration feeling. When the user holds the aerosol generating device 100, the vibration of the vibrator can give the user a strong feedback, which is convenient for the user to find the signal in time.

[0153] In some other embodiments, the aerosol generating device 100 may be controlled to emit an inhalable signal by:

[0154] The signal light controlling the aerosol generating device 100 flashes.

[0155] The number of times and frequency of the signal light flashing are not limited. For example, it can flash in the form of a breathing light.

[0156] In a specific embodiment, the control method of the aerosol generating device 100 includes the following steps:

[0157] Step S501: Turn on the aerosol generating device 100;

[0158] Step S502: controlling the heating element of the aerosol generating device 100 to generate heat, the vibrator to vibrate once, and the signal light to flash once;

[0159] The vibrator and the signal light prompt the user, indicating that the aerosol generating device 100 has been turned on.

[0160] Step S503: determining that the continuous heating time of the heating element reaches a first set time;

[0161] At this time, the air supply component 10 has met the opening condition, and the air supply component 10 can be controlled to open.

[0162] Step S504: controlling the air supply assembly 10 to supply air to the accommodating chamber 20a;

[0163] Step S505: determining that the continuous working time of the air supply component 10 reaches a second set time;

[0164] At this time, the aerosol generating device 100 is already in an inhalable state, and the aerosol generating device 100 can be controlled to send an inhalable signal.

[0165] Step S506: Control the vibrator to vibrate once, and control the signal light to flash in the form of a breathing light.
