Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0047] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] This application is based on the technical problem that as the aerosol generating matrix is ​​consumed during the aerosol generating process, the aerosol atomization amount is easily reduced, resulting in a decrease in the taste. An aerosol generating device is provided, in which a controller is electrically connected to an air regulating valve to control the action of the air regulating valve. The controller can obtain the reserve information of the liquid aerosol generating matrix, and adjust the air inlet area of ​​the atomization channel according to the reserve information of the aerosol generating matrix to ensure a stable taste for the user. For details, refer to the following embodiments.

[0049] Please refer to Figure 1 , Figure 2 and Figure 3 In a first embodiment of the present application, an aerosol generating device 10 is provided, including an atomizing element 11, a liquid storage tank 12, an air regulating valve 13 and a controller 14.

[0050] The atomizer 11 is provided with an atomizer channel 111. The atomizer 11 heats the liquid aerosol generating matrix and forms an aerosol in the atomizer channel 111. The aerosol flows along the atomizer channel 111 to the suction nozzle 16 and flows out from the suction nozzle 16 for the user to inhale. The liquid storage tank 12 stores the liquid aerosol generating matrix and provides the liquid aerosol generating matrix for the atomizer 11. The atomizer 11 is at least partially placed in the liquid storage tank 12, so that the atomizer 11 can directly absorb the liquid aerosol generating matrix in the liquid storage tank 12. The air regulating valve 13 is installed at the air inlet of the atomizer channel 111, and is used to adjust the air inlet area of ​​the atomizer channel 111.

[0051] The external air flows into the atomizing channel 111 from the air inlet of the atomizing channel 111, and flows out of the atomizing channel 111 together with the aerosol. The air inlet area of ​​the atomizing channel 111 is adjusted by the air regulating valve 13 to change the flow rate and air intake of the air flow entering the atomizing channel 111, thereby changing the concentration of the aerosol flowing to the user through the suction nozzle 16 and adjusting the user's inhalation taste.

[0052] Since the atomizer 11 continuously consumes the liquid aerosol generating matrix in the liquid storage tank 12, the reserve of the liquid aerosol generating matrix continues to decrease, so that the aerosol atomization amount generated by the atomizer 11 shows a decreasing trend, which reduces the aerosol concentration used by the user and causes the taste to decay. By installing a controller 14 in the aerosol generating device 10, the controller 14 is electrically connected to the air regulating valve 13 to control the action of the air regulating valve 13. The controller 14 can obtain the reserve information of the liquid aerosol generating matrix and adjust the size of the air inlet area according to the reserve information. Specifically, the larger the value of the reserve information, the smaller the area of ​​the air inlet is adjusted.

[0053] For example, when the value of the aerosol generation substrate storage information decreases to a preset value, the air regulating valve 13 is driven to increase the air inlet area of ​​the atomization channel 111, so that the air intake of the atomization channel 111 increases. As the aerosol generation substrate storage decreases, the atomization amount of the aerosol decreases accordingly. By increasing the air inlet area entering the atomization channel 111 to increase the air intake, the amount of aerosol flowing to the user increases, so as to ensure a stable taste for the user.

[0054] In one embodiment, the size of the air inlet area is adjusted according to the value of the reserve information. It can be considered that based on the range of the reserve information value, when the reserve information is in a first preset range, the area of ​​the air inlet is equal to the first preset area. When the reserve information is in a second preset range, the area of ​​the air inlet is equal to the second preset area. The air inlet area can be determined by the number of air inlets, the size of the opening and closing area of ​​a single air inlet, etc. The two preset ranges given above realize the adjustment of two corresponding air inlet areas, that is, there are two adjustment gears for the air intake size.

[0055] In another embodiment, the air intake area can further increase the adjustment gears to make the intake volume adjustment more precise: when the reserve information is in the third preset range, the area of ​​the air intake is equal to the third preset area, that is, three gears of adjustment are achieved. Of course, more preset ranges can also be set to perform corresponding air intake area size adjustments, which is not limited in the present application, to further improve the sensitivity of the adjustment.

[0056] The controller 14 can adopt a control circuit in the form of an integrated circuit to form a control circuit board for obtaining the storage information of the aerosol generating matrix, and then controlling the action of the air regulating valve 13 according to the storage information to ensure the stability of the user's inhalation taste.

[0057] At the beginning of use, the storage volume of the aerosol generating matrix in the liquid storage tank 12 is relatively large, close to 100%. At this time, the aerosol atomization amount generated by the atomizer 11 is large, and the corresponding air intake volume of the atomization channel 111 does not need to be too large, that is, the air inlet area does not need to be too large, and the mixed air flow of aerosol and air flowing to the user has a better taste.

[0058] As the reserve of the aerosol generating matrix is ​​consumed, the amount of aerosol generated by the atomizer 11 decreases, and it is necessary to increase the air intake of the atomizer channel 111, that is, to increase the air intake area, to ensure that the amount of aerosol in the mixed airflow of aerosol and air flowing to the user is sufficient to ensure that the user has a good taste, to ensure a stable taste, and to prevent taste attenuation. The preset value is not limited to a certain value, and may also refer to a certain range of values. The amount of aerosol generated by the atomizer 11 is gradually reduced, not a cliff-like reduction. Therefore, when the user continues to inhale and use it, the user cannot directly and clearly feel the change in taste. Only when the amount of aerosol is reduced to a certain value or range of values, the user can have a clear taste difference, and there is no need to continuously adjust the air intake of the atomizer channel 111.

[0059] By setting a preset value in the controller 14, the storage amount of the aerosol generating substrate is compared with the preset value. Only when the value of the storage information reaches the preset value, the air intake of the atomizing channel 111 is adjusted, so as to ensure the user's puffing taste is stable. The storage information of the liquid aerosol generating substrate can be determined by liquid level detection, puffing number estimation, heating time estimation, etc.

[0060] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In one embodiment, two atomizing elements 11 may be provided, and the air inlet ends of the atomizing channels 111 of the two atomizing elements 11 may have different sizes or may be the same.

[0061] Specifically, the cross-sectional areas of the air inlet ends of the atomizing channels 111 of the two atomizing elements 11 are different in size. Figure 4 As shown, two holes with different apertures can be respectively provided for the two atomizers 11 on the support 123 for mounting the atomizer 11. Figure 4 The middle arrow points to the hole, which serves as the air inlet end of the atomization channel 111, so that the two atomization channels 111 form an unbalanced air channel, thereby increasing the heat dissipation of the heating wire in the atomization element 11 far away from the hole.

[0062] The atomizer 11 includes a heating net 112 and at least two conductive ends 113. The heating net 112 is connected to the conductive ends 113, and the conductive ends 113 are connected to the battery 17 for power supply. Figure 5 As shown on the right, a narrow gap is formed at the connection position between the heating net 112 and the conductive end 113, which affects the heat dissipation. Figure 5As shown on the left, the mesh holes 1121 at the end where the heating net 112 and the conductive end 113 are connected are of the same size, so as to avoid the formation of a slit at the connection position between the heating net 112 and the conductive end 113, which affects the heat dissipation, thereby optimizing the heat dissipation at the edge where the heating net 112 and the conductive end 113 are connected, increasing the heat dissipation area at the edge of the heating net 112, slowing down the carbon deposition at the edge of the heating net 112, and reducing the carbon deposition problem of the heating net 112 when the aerosol generation matrix reserves are reduced. Since the carbon deposition of the heating net 112 will become more serious as the puffing time increases during the puffing process, making the puffing taste worse, the above-mentioned setting can slow down the carbon deposition, which is conducive to ensuring the user's puffing taste experience.

[0063] Please refer to Figure 2 , the liquid storage tank 12 can be made of PCTG (transparent plastic) material and molded by mold injection. The liquid storage tank 12 may include a tank body 121, a sealing silicone cover 122 and a support 123. The tank body 121 is hollow, and the top and bottom ends of the tank body 121 have openings. The sealing silicone cover 122 is made of silicone material and is molded by mold injection, and has an interference fit with the top opening of the tank body 121. The support 123 is used to install the atomizer 11 and is connected to the bottom opening of the tank body 121. The tank body 121, the sealing silicone cover 122 and the support 123 together enclose a space for storing a liquid aerosol generating matrix, and the atomizer 11 is at least partially located in the cavity. A liquid storage cotton 124 is also provided in the liquid storage tank 12, and the liquid storage cotton 124 adsorbs and stores the liquid aerosol generating matrix.

[0064] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 In another embodiment, the air regulating valve 13 is provided with at least two air inlet holes 131 with different apertures, and the two ends of the air inlet hole 131 are respectively used to connect the air inlet of the atomizing channel 111 and the outside of the aerosol generating device 10, so that the external airflow enters the atomizing channel 111 through the air inlet hole 131, and ensures that the airflow of the atomizing channel 111 is smooth, so that the user can inhale the aerosol. The air regulating valve 13 switches the air inlet holes 131 with different apertures to communicate with the air inlet of the atomizing channel 111, so as to adjust the size of the air inlet area of ​​the atomizing channel 111.

[0065] Please refer to Figure 6, the air regulating valve 13 can be provided with more than two air inlets with different apertures, for example, the air inlet 131 includes air hole No. 1, air hole No. 2, air hole No. 3 and air hole No. 4 with decreasing apertures in sequence, that is, the aperture of air hole No. 1 is the largest, and the aperture of air hole No. 4 is the smallest. When the reserve of the aerosol generating matrix accounts for 30% of the liquid storage tank 12, the air regulating valve 13 switches the air hole No. 1 to be connected with the air inlet of the atomizing channel 111. At this time, the air intake volume is the largest, and the fragrance reduction degree of the atomization is improved by a large air flow. When the reserve of the aerosol generating matrix accounts for 60% of the liquid storage tank 12, the air hole No. 2 is selected. At this time, the air flow is switched to a slightly smaller air hole to increase the flow rate of the air flow, speed up the air flow rate in the atomizing channel 111, reduce the temperature of the heating network 112, and improve the life of the heating network 112. When the amount of the aerosol generating substrate accounts for 80% of the liquid storage bin 12, the air hole No. 3 is selected, and the air flow is switched to a slightly smaller air hole to increase the flow rate of the air flow, accelerate the flow of the air flow in the atomization channel 111, reduce the temperature of the heating net 112, and increase the life of the heating net 112. When the amount of the aerosol generating substrate accounts for 90% of the liquid storage bin 12, the air hole No. 4 is selected, and the air flow is switched to a slightly smaller air hole to increase the flow rate of the air flow, accelerate the flow of the air flow in the atomization channel 111, reduce the temperature of the heating net 112, and increase the life of the heating net 112.

[0066] The aerosol generating device 10 is provided with a display screen for displaying the storage amount of the aerosol generating substrate, which can be displayed in the form of percentage, such as 30%, 60%, 80%, 90%, so that the user can intuitively understand the storage amount of the aerosol generating substrate. The display screen is electrically connected to the controller 14, and the controller 14 sends the storage amount information of the aerosol generating substrate to the display screen for display.

[0067] In one embodiment, when the area of ​​the air inlet is equal to the first preset area, the controller 14 controls the battery 17 to output the first output voltage to power the atomizer 11. When the area of ​​the air inlet is equal to the second preset area, the controller 14 controls the battery 17 to switch to the second output voltage to power the atomizer 11, wherein the second output voltage is greater than the first output voltage.

[0068] After the reserve of the liquid aerosol generating matrix decreases, the aerosol atomization amount of the atomizer 11 decreases accordingly. By increasing the output voltage of the battery that supplies power to the atomizer 11 and the battery output cut-off voltage, it is beneficial to increase the aerosol atomization amount of the atomizer 11, ensure the stability of the aerosol concentration flowing to the user, and improve the stability of the user's inhalation taste. According to the preset range of the reserve information, the area of ​​the air inlet is adjusted to the corresponding preset area, and then the battery 17 is controlled to supply power to the atomizer 11 with the corresponding different output voltages. For example: when the value of the reserve information decreases, the corresponding air inlet area is adjusted to increase, and then the output voltage is adjusted to increase, the aerosol atomization amount is increased, and the aerosol concentration flowing to the user is guaranteed to be stable.

[0069] Furthermore, the cut-off voltage can determine the working range of the circuit. Before the controller 14 controls the battery 17 to switch from the first output voltage to the second output voltage, the battery 17 supplies power to the atomizer 11 at the first cut-off voltage, wherein the first cut-off voltage is less than the first output voltage. By adjusting the cut-off voltage of the power supply, it is helpful to ensure the accuracy of the output voltage control, thereby achieving accurate adjustment of the atomization amount.

[0070] In another embodiment, the frequency of adjusting the air intake volume can be increased. When the area of ​​the air intake port is equal to the third preset area, the controller 14 controls the battery 17 to switch to the third output voltage output to power the atomizer 11, wherein the third output voltage is greater than the second output voltage. Before the controller 14 controls the battery 17 to switch from the second output voltage to the third output voltage, the battery 17 powers the atomizer 11 with the second cutoff voltage, wherein the second cutoff voltage is less than the second output voltage. It is possible to achieve multi-frequency adjustment of the atomization volume according to the value of the reserve information, thereby improving the accuracy of the atomization volume adjustment.

[0071] The controller 14 is used to obtain the storage information of the liquid aerosol generating matrix, including obtaining the cumulative number of puffs of the aerosol generating device, and comparing the cumulative number of puffs with the preset value of puffing. And / or, obtaining the cumulative heating time of the atomizer 11, and comparing the cumulative heating time with the preset value of heating. The number of puffs available for puffing / the time available for heating and atomization after the liquid storage tank is full of liquid aerosol generating matrix can be calculated by the software algorithm, and then the proportion of the corresponding storage of the liquid aerosol generating matrix can be obtained according to the actual cumulative number of puffs / heating time.

[0072] At this time, the preset value is the cumulative number of puffs / cumulative heating time corresponding to different reserves of the liquid aerosol generating matrix. When the cumulative number of puffs / cumulative heating time reaches the preset value, the reserve of the aerosol generating matrix can be roughly determined. By comparing the cumulative number of puffs with the preset value and / or the cumulative heating time with the preset value, the reserve of the aerosol generating matrix can be roughly determined, and then the size of the air inlet area can be adjusted according to the different reserves, so that the amount of aerosol flowing to the user remains stable, which is conducive to improving the stability of the user's taste.

[0073] In one embodiment, the controller 14 is used to obtain the storage information of the liquid aerosol generating substrate, including obtaining the cumulative number of puffs of the aerosol generating device, and comparing the cumulative number of puffs with the preset puff value. The number of puffs that can be puffed after the liquid storage tank 12 is full of the liquid aerosol generating substrate is calculated through a software algorithm, and then the proportion of the storage of the liquid aerosol generating substrate corresponding to the actual cumulative number of puffs / heating time can be obtained.

[0074] The detailed comparison process may be: if the cumulative number of puffs of the aerosol generating device is less than the first puff preset value, the reserve information is within the first preset range. If the cumulative number of puffs of the aerosol generating device is greater than the first puff preset value and less than the second puff preset value, the reserve information is within the second preset range. If the cumulative number of puffs of the aerosol generating device is greater than the second puff preset value and less than the third puff preset value, the reserve information is within the third preset range.

[0075] In another embodiment, the controller 14 is used to obtain the storage information of the liquid aerosol generating substrate, including obtaining the cumulative heating time of the atomizer 11, and comparing the cumulative heating time with the heating preset value. The time for the liquid storage tank 12 to be full of liquid aerosol generating substrate for heating and atomization can be calculated by a software algorithm, and then the proportion of the storage of the liquid aerosol generating substrate corresponding to the heating time can be obtained.

[0076] The detailed comparison process may also be: if the cumulative heating time of the atomizer 11 is less than the first heating preset value, the reserve information is within the first preset range. If the cumulative heating time of the atomizer 11 is greater than the first heating preset value and less than the second heating preset value, the reserve information is within the second preset range. If the cumulative heating time of the atomizer 11 is greater than the second heating preset value and less than the third heating preset value, the reserve information is within the third preset range.

[0077] In another embodiment, the controller 14 is used to obtain the storage information of the liquid aerosol generating substrate, including obtaining the cumulative number of puffs of the aerosol generating device, and comparing the cumulative number of puffs with the preset puff value; on the other hand, the controller 14 is used to obtain the storage information of the liquid aerosol generating substrate, obtain the cumulative heating time of the atomizer, and compare the cumulative heating time with the preset heating value. The controller 14 can obtain the proportion of the corresponding storage of the liquid aerosol generating substrate by combining the actual cumulative number of puffs / heating time.

[0078] Please continue to refer to Figure 1 , Figure 2 , Figure 3 and Figure 6Furthermore, the air regulating valve 13 includes a valve body 132 and a valve plate 133. The valve body 132 is a rotary driving component, which can specifically be a servo motor, electrically connected to the controller 14, and the rotation angle of the rotary driving shaft of the valve body 132 is controlled by the controller 14. The valve plate 133 is installed on the rotary driving shaft of the valve body 132. Among them, the air inlet hole 131 is located on the valve plate 133, and is distributed around the rotation axis of the valve plate 133, so that when the valve body 132 drives the valve plate 133 to rotate, the air inlet hole 131 switches position around the rotation axis. Under the rotation drive of the valve body 132, the valve plate 133 switches the air inlet holes 131 of different apertures to be connected with the air inlet of the atomization channel 111, thereby realizing the switching and adjustment of the size of the intake airflow of the atomization channel 111.

[0079] The aerosol generating device 10 includes a shell 15. The shell 15 can be made of PC (polycarbonate), and the shell 15 is gap-matched with the liquid storage tank 12 and the suction nozzle 16 for easy assembly. The shell 15 is provided with an air inlet channel 151. The two ends of the air inlet hole 131 are respectively used to connect the air inlet of the atomization channel 111 and the air inlet channel 151, and the external air enters the atomization channel 111 through the air inlet channel 151 and the air inlet hole 131 in turn. The valve body 132 in the air regulating valve 13 drives the valve plate 133 to rotate, and the air inlet holes 131 of different apertures on the valve plate 133 are rotated and switched to be connected with the air inlet channel 151, so as to adjust the size of the air inlet of the atomization channel 111, and realize the switching and adjustment of the size of the air intake airflow of the atomization channel 111.

[0080] The housing 15 is provided with an arc-shaped guide groove 152, which is circumferentially extended relative to the rotation axis of the valve plate 133, and has a limiting function on the rotation angle of the valve plate 133. The valve plate 133 is provided with a guide rod 134, which is inserted into the arc-shaped guide groove 152. When the valve plate 133 rotates, the guide rod 134 moves along the arc-shaped guide groove 152. Through the cooperation between the guide rod 134 and the arc-shaped guide groove 152, the rotation angle of the valve plate 133 is limited, so as to avoid the valve plate 133 rotating too much, so that the air inlet hole 131 on the valve plate 133 cannot be aligned and connected with the air inlet channel 151, thereby effectively ensuring the accuracy of switching and adjusting the size of the air inlet airflow of the atomizing channel 111.

[0081] See also Figure 7 In a second embodiment of the present application, there is provided an aerosol generating method based on the aerosol generating device as described above, comprising the steps of:

[0082] S100, obtaining the storage amount of the liquid aerosol generating substrate, and comparing the storage amount of the liquid aerosol generating substrate with a preset value. The preset value includes a first preset value and a second preset value, and the second preset value is less than the first preset value. The preset value, the first preset value, and the second preset value correspond to a certain storage amount or storage range of the liquid aerosol generating substrate.

[0083] S200A: If the storage amount of the liquid aerosol generating substrate reaches a first preset value or a second preset value, the first air inlet hole or the second air inlet hole is switched to be connected to the air inlet of the atomizing channel of the atomizing element, wherein the first air inlet hole is smaller than the second air inlet hole.

[0084] Since the second preset value is less than the first preset value, the reserve of the liquid aerosol generating matrix reaches the second preset value, and the reserve is consumed and reduced compared to when it reaches the first preset value, that is, during normal consumption, the reserve first reaches the first preset value, and then reaches the second preset value after consumption, so that the aerosol atomization amount generated by the atomizer is reduced, and the aerosol concentration flowing to the user is reduced, causing the user's taste to decay. Since the first air inlet is smaller than the second air inlet, when the reserve is consumed and reaches the first preset value, the reserve is more than when it reaches the second preset value after consumption, so that the generated aerosol atomization amount is more, and the use of a relatively small first air inlet connected to the atomization channel can provide the user with sufficient aerosol concentration to ensure the user's taste, and when the reserve continues to be consumed to reach the second preset value, the reserve is reduced, so that the generated aerosol atomization amount is reduced, and a relatively large second air inlet is used to connect to the atomization channel to increase the air intake, so that more aerosol flows to the user, which can ensure the user's taste stability.

[0085] The aerosol generation method provided in the present application adjusts the air inlet holes of different apertures to be connected to the atomization channel according to the different reserves of the liquid aerosol generation matrix in the aerosol generation device, so that the amount of aerosol flowing to the user remains stable, which is beneficial to improving the stability of the user's taste.

[0086] See also Figure 8 In the third embodiment of the present application, a method for generating an aerosol is provided, comprising the steps of:

[0087] S100, obtaining the storage amount of the liquid aerosol generating substrate, and comparing the storage amount of the liquid aerosol generating substrate with a preset value, wherein the preset value includes a first preset value and a second preset value, and the second preset value is smaller than the first preset value.

[0088] S200B, if the storage amount of the liquid aerosol generating substrate reaches the first preset value or the second preset value, the output voltage of the battery for powering the atomizer is switched to the first output voltage or the second output voltage, and the output cut-off voltage of the battery for powering the atomizer is switched to the first output cut-off voltage or the second output cut-off voltage. The first output voltage is less than the second output voltage, and the first output cut-off voltage is less than the second output cut-off voltage.

[0089] After the reserve of the liquid aerosol generating matrix is ​​reduced, the aerosol atomization amount of the atomizer is reduced accordingly. By increasing the output voltage of the battery that powers the atomizer and the battery output cut-off voltage, it is beneficial to increase the aerosol atomization amount of the atomizer, ensure the stability of the aerosol concentration flowing to the user, and improve the stability of the user's inhalation taste. Since the second preset value is less than the first preset value, the reserve of the liquid aerosol generating matrix reaches the second preset value, and the reserve is consumed and reduced compared to when it reaches the first preset value, that is, when it is used normally, the reserve first reaches the first preset value, and then reaches the second preset value after consumption, so that the aerosol atomization amount generated by the atomizer is reduced, and the concentration of the aerosol flowing to the user is reduced, causing the user's taste to decay. Since the first output voltage is less than the second output voltage, and the first output cut-off voltage is less than the second output cut-off voltage, when the reserve is consumed to reach the first preset value, the reserve is greater than when it is consumed later to reach the second preset value, so that the generated aerosol atomization amount is greater, and the control battery uses a relatively small first output voltage and a first output cut-off voltage to power the atomizer. The atomizer can provide the user with sufficient aerosol concentration to ensure the user's taste. When the reserve continues to be consumed to reach the second preset value, the reserve is reduced, so that the generated aerosol atomization amount is reduced. The control battery uses a relatively large second output voltage and a second output cut-off voltage to power the atomizer, thereby increasing the aerosol atomization amount of the atomizer, so that more aerosol flows to the user, which can ensure a stable taste for the user.

[0090] The aerosol generation method provided in the present application adjusts the output voltage and output cut-off voltage of the battery for powering the atomizer according to the different reserves of the liquid aerosol generation matrix in the aerosol generation device, so that the amount of aerosol flowing to the user remains stable, which is beneficial to improving the stability of the user's taste.

[0091] See also Fig. 9 In a fourth embodiment of the present application, a method for generating an aerosol is provided, comprising the steps of:

[0092] S100, obtaining the storage amount of the liquid aerosol generating substrate, and comparing the storage amount of the liquid aerosol generating substrate with a preset value, wherein the preset value includes a first preset value and a second preset value, and the second preset value is smaller than the first preset value.

[0093] S200C: If the storage amount of the liquid aerosol generating substrate reaches the first preset value or the second preset value, the input voltage of the atomizing element is switched to the first input voltage or the second input voltage, and the input cut-off voltage of the atomizing element is switched to the first input cut-off voltage or the second input cut-off voltage. The first input voltage is less than the second input voltage, and the first input cut-off voltage is less than the second input cut-off voltage.

[0094] After the reserve of the liquid aerosol generating matrix decreases, the aerosol atomization amount of the atomizer decreases accordingly. By increasing the input voltage and input cut-off voltage of the atomizer, it is beneficial to increase the aerosol atomization amount of the atomizer, ensure the stability of the aerosol concentration flowing to the user, and improve the stability of the user's suction taste. Since the second preset value is less than the first preset value, the reserve of the liquid aerosol generating matrix reaches the second preset value, and the reserve is consumed and reduced compared to when it reaches the first preset value, that is, during normal consumption, the reserve first reaches the first preset value, and then reaches the second preset value after consumption, so that the aerosol atomization amount generated by the atomizer is reduced, and the concentration of the aerosol flowing to the user is reduced, causing the user's taste to decay. Since the first input voltage is smaller than the second input voltage, and the first input cut-off voltage is smaller than the second input cut-off voltage, when the reserve is consumed to reach the first preset value, the reserve is larger than when it reaches the second preset value after consumption, so that the generated aerosol atomization amount is larger, and the input voltage of the atomizer is controlled to adopt a relatively small first input voltage and a first input cut-off voltage, so that the atomizer can provide the user with sufficient aerosol concentration to ensure the user's taste. When the reserve continues to be consumed to reach the second preset value, the reserve is reduced, so that the generated aerosol atomization amount is reduced, and the input voltage of the atomizer is controlled to adopt a relatively large second input voltage and a second input cut-off voltage, so as to increase the aerosol atomization amount of the atomizer, so that more aerosol flows to the user, which can ensure the user's taste is stable.

[0095] The aerosol generation method provided in the present application adjusts the input voltage and input cut-off voltage of the atomizer according to the different reserves of the liquid aerosol generation matrix in the aerosol generation device, so that the amount of aerosol flowing to the user remains stable, which is beneficial to improving the stability of the user's taste.

[0096] In one embodiment, the step S100 specifically includes the following steps:

[0097] S10A, obtaining the cumulative number of puffs, and comparing the cumulative number of puffs with a preset value.

[0098] The number of puffs available for inhalation after the liquid aerosol generating matrix is ​​filled in the liquid storage tank can be calculated by the algorithm of the software, and then the proportion of the corresponding liquid aerosol generating matrix reserve can be known according to the actual accumulated number of puffs. At this time, the preset value is the accumulated number of puffs corresponding to the different reserves of the liquid aerosol generating matrix. For example, the first preset value corresponds to the reserve of the aerosol generating matrix accounting for 60% or 40% of the liquid storage tank, and the second preset value corresponds to the reserve of the aerosol generating matrix accounting for 90% or 80% of the liquid storage tank, that is, when the number of puffs is accumulated, as the reserve is consumed, the number of puffs increases, and the corresponding value of the preset value increases. When the accumulated number of puffs reaches the preset value, the reserve of the aerosol generating matrix can be roughly determined.

[0099] If the storage amount of the liquid aerosol generating substrate reaches the first preset value or the second preset value in step S200A, S200B or S200C, the steps specifically include:

[0100] If the accumulated number of puffs reaches the second preset value or the first preset value, since the second preset value is less than the first preset value, the reserve when the accumulated number of puffs reaches the second preset value is greater than the reserve when the accumulated number of puffs reaches the first preset value.

[0101] By comparing the cumulative number of puffs with a preset value, the reserve of the aerosol generating matrix can be roughly determined, and then, according to the different reserves, the air inlet holes of different apertures can be adjusted to be connected to the atomization channel, or the output voltage and output cut-off voltage of the battery for powering the atomizer can be adjusted, or the input voltage and input cut-off voltage of the atomizer can be adjusted, so that the amount of aerosol flowing to the user remains stable, which is beneficial to improving the stability of the user's taste.

[0102] In another embodiment, the step S100 specifically includes the steps of:

[0103] S10B, obtaining the accumulated heating time, and comparing the accumulated heating time with a preset value.

[0104] The software algorithm can be used to calculate the time available for heating and atomization after the liquid storage tank is full of liquid aerosol generating matrix, and then the proportion of the corresponding liquid aerosol generating matrix reserves can be known according to the accumulated heating time. At this time, the preset value is the accumulated heating time corresponding to the different reserves of the liquid aerosol generating matrix. For example, the first preset value corresponds to the reserves of the aerosol generating matrix accounting for 60% or 40% of the liquid storage tank, and the second preset value corresponds to the reserves of the aerosol generating matrix accounting for 90% or 80% of the liquid storage tank, that is, when the accumulated heating time is consumed, the heating time increases, and the value of the preset value increases. When the accumulated number of puffs reaches the preset value, the reserves of the aerosol generating matrix can be roughly determined.

[0105] If the storage amount of the liquid aerosol generating substrate reaches the first preset value or the second preset value in step S200A, S200B or S200C, the steps specifically include:

[0106] If the accumulated heating time reaches the second preset value or the first preset value, since the second preset value is less than the first preset value, the reserve when the accumulated heating time reaches the second preset value is greater than the reserve when the accumulated heating time reaches the first preset value.

[0107] By comparing the accumulated heating time with the preset value, the reserve of the aerosol generating matrix can be roughly determined, and then, according to the different reserves, the air inlet holes of different apertures can be adjusted to be connected to the atomization channel, or the output voltage and output cut-off voltage of the battery for powering the atomizer can be adjusted, or the input voltage and input cut-off voltage of the atomizer can be adjusted, so that the amount of aerosol flowing to the user remains stable, which is beneficial to improving the stability of the user's taste.

[0108] See also Fig.10 , the preset value is not limited to only the first preset value and the second preset value, and more preset values ​​can be set, such as the third preset value, and the values ​​of the third preset value, the second preset value, and the first preset value increase in sequence. As shown in the figure, the third preset value is 1200 seconds, the second preset value is 1550 seconds, and the first preset value is 1780 seconds. Correspondingly, the first output voltage is set to 3.5V, the second output voltage is set to 3.6V, the third output voltage is set to 3.7V, the first output cut-off voltage is set to 3.3V, the second output cut-off voltage is set to 3.4V, and the third output cut-off voltage is set to 3.5V.

The controller can obtain the reserve of a liquid aerosol generating matrix, and adjust the air inlet area of ​​an atomizing channel according to the reserve information of the aerosol generating matrix to ensure a stable taste for the user.
