Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation.

For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0055] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0056] It is worth noting that the "aerosol generating substrate" in the present invention refers to a substrate capable of releasing volatile compounds capable of forming an aerosol. Such volatile compounds can be released by heating the aerosol generating substrate. As an alternative to heating or burning, in some cases, the volatile compounds can be released by chemical reactions or by mechanical stimulation such as ultrasound. The aerosol generating substrate in the present invention can be liquid or include solid and liquid components. The aerosol forming substrate may include nicotine. The aerosol forming substrate may also include at least one aerosol precursor, such as propylene glycol or glycerol.

[0057] It is worth noting that the "aerosol generating device" in the present invention refers to a device that interacts with an aerosol generating substrate to generate an aerosol.

[0058] like Figure 1 to Figure 3 The working process of controlling the liquid delivery component and the atomization component of the aerosol generating device shown, and Figures 4 to 9 The present invention provides a control method for an aerosol generating device, wherein the aerosol generating device comprises a liquid storage chamber 50, a liquid delivery component, an atomizing component and a control component, wherein the atomizing component comprises a first buffer 31 and an atomizing element 32,

[0059] The control component is used to control the liquid delivery component to continuously deliver the aerosol generating matrix to the atomization component within a first time period T1, and is also used to control the atomization component to continuously atomize the aerosol generating matrix it receives within a second time period T2, wherein the first time period T1 is longer than the second time period T2, and the first time period T1 and the second time period T2 partially overlap.

[0060] By adopting this technical solution, the control component controls the liquid delivery component to actively deliver oil, effectively avoiding oil leakage and oil explosion; and the time for the liquid delivery component to deliver the aerosol-generating matrix is ​​longer than the working time of the atomization component, which can ensure that the atomization component is adequately supplied with oil and avoid dry burning.

[0061] Preferably, the start time of the first time period T1 is not later than the start time of the second time period T2, and the end time of the first time period T1 is not earlier than the end time of the second time period T2. During the second time period T2 of the atomizer assembly, the liquid delivery assembly always delivers the aerosol-generating substrate to the atomizer assembly, further effectively avoiding dry burning.

[0062] According to a preferred embodiment of the present invention, Figure 1 As shown, the start time of the first time period T1 is earlier than the start time of the second time period T2, and the first time period T1 and the second time period T2 end at the same time.

[0063] Specifically, if Figure 1 As shown, after the sensing unit of the control component senses the user's use action, such as suction sensing, pressing the switch, etc., it first controls the liquid delivery component to transmit the aerosol generating matrix to the atomizing component, and the transmitted aerosol generating matrix is ​​cached on the first cache part 31 of the atomizing component. After a certain delay, the control component controls the atomizing component to start atomization. After working for a period of time, when the control component senses the user's closing action, it turns off the liquid delivery component and the atomizing component, and stops the transmission and atomization of the aerosol generating matrix. By caching the aerosol generating matrix for a period of time before the atomizing component works, the temperature of the atomizing component is avoided from rising rapidly, and the liquid delivery component has not yet provided enough aerosol generating matrix to the atomizing component, and the possible scorching and dry burning problems may exist.

[0064] Furthermore, to ensure the user experience, the delay time does not exceed 1s. If the time is too long, it will affect the user experience. The best delay time is between 0.5s-1s, that is, the start time of the first time period T1 is 0.5~1s earlier than the start time of the second time period T2. This can ensure that when the atomizer component is working, the atomizer component already has a certain amount of aerosol generating matrix.

[0065] According to a preferred embodiment of the present invention, Figure 2As shown, the first time period T1 and the second time period T2 start at the same time, and the end time of the first time period T1 is later than the end time of the second time period T2.

[0066] Specifically, after the sensing unit of the control component senses the user's use action, such as suction sensing, pressing the switch, etc., the liquid delivery component is controlled to transmit the aerosol-generating matrix to the atomizing component, and the atomizing component starts to atomize the aerosol-generating matrix. After working for a period of time, after the control component senses the user's closing action, it does not stop the transmission and atomization of the aerosol-generating matrix at the same time, but first stops the atomization of the aerosol-generating matrix, and then stops the liquid delivery component from providing the aerosol-generating matrix to the atomizing component after a period of time. The aerosol-generating matrix will be cached on the first cache part 31 of the atomizing component to prepare for the next atomization, thereby solving the coking and dry burning problems that may exist due to the rapid temperature rise of the atomizing component, and the atomizing component is immediately started after sensing the user's use action, which can reduce the smoke response time and improve the user experience.

[0067] Furthermore, in this solution, the liquid delivery component is closed 0.5s-2s later, that is, the end time of the first time period T1 is 0.5-2s later than the end time of the second time period T2, ensuring that the amount of smoke oil delivered during this time does not exceed the maximum buffer capacity of the atomizer component.

[0068] According to a preferred embodiment of the present invention, the start time of the first time period T1 is earlier than the start time of the second time period T2, and the end time of the first time period T1 is later than the end time of the second time period T2.

[0069] Specifically, if Figure 3As shown, after the sensing unit of the control component senses the user's usage action, such as suction sensing, pressing the switch, etc., it does not open the liquid delivery component and the atomization component at the same time, but first opens the liquid delivery component to transmit the aerosol generating matrix, and the transmitted aerosol generating matrix is ​​cached by the first cache part 31 on the atomization element 32, and the atomization component is opened after a certain delay to atomize the aerosol generating matrix. After working for a period of time, when the control component sensing unit senses the user's closing action, it does not close the liquid delivery component and the atomization component at the same time, but first closes the atomization component to stop the aerosol generating matrix atomization, delays the closing of the liquid delivery component, continues to transmit the aerosol generating matrix to the atomization component, and caches it in the first cache part 31 of the atomization element 32. After caching a certain amount of aerosol generating matrix, the liquid delivery component is closed and the transmission of the aerosol generating matrix is ​​stopped to prepare for the next use, thereby solving the carbonization and dry burning problems that may exist due to the rapid temperature rise of the atomization element 32, shortening the delayed start time before the atomization component works, accelerating the smoke response speed, improving the user experience, and after the atomization component finishes working, the time for delaying the closing of the liquid delivery component is also shortened, reducing the cache amount of the aerosol generating matrix in the first cache part 31, which can reduce the possibility of waste of the aerosol generating matrix.

[0070] In this technical solution, it is preferred that the sum of the two delay times does not exceed 2 seconds. If the time is too long, the amount of aerosol-generating substrate transmission may exceed the maximum buffer capacity of the first buffer section 31. That is, the start time of the first time period T1 is earlier than the start time of the second time period T2, and the end time of the first time period T1 is later than the end time of the second time period T2. The first time period T1 is no longer than the second time period T2 by no more than 2 seconds.

[0071] It is worth noting that Figure 1 to Figure 3 The ordinate is voltage, wherein the voltage of the atomizing assembly is higher than the voltage of the liquid transmission assembly. However, this does not limit the voltage of the atomizing assembly to be higher than the voltage of the liquid transmission assembly. This is only for distinguishing and displaying the working states of the atomizing assembly and the liquid transmission assembly. The voltage of the atomizing assembly may be greater than, equal to or less than the voltage of the liquid transmission assembly. The specific voltage may be determined based on actual conditions and actual needs, such as the specific atomizing assembly and liquid transmission assembly used, without any special restrictions.

[0072] According to another specific embodiment of the present invention, the present invention also provides an aerosol generating device, including a liquid storage chamber 50, a liquid delivery component, an atomizing component and a control component, the atomizing component including a first buffer 31 and an atomizing element 32, and the control component is used to control the aerosol generating device to implement any of the aforementioned control methods. With this technical solution, the liquid delivery component is controlled by the control component to actively deliver oil, effectively avoiding oil leakage and oil explosion; and the time for the liquid delivery component to deliver the aerosol generating matrix is ​​longer than the working time of the atomizing component, which can ensure that the atomizing component is adequately supplied with oil to avoid dry burning.

[0073] Furthermore, the liquid delivery component is a liquid flow pump 11, such as a piezoelectric pump or a peristaltic pump. Figure 4 As shown, the liquid flow pump 11 includes a liquid inlet 12 and a liquid outlet 13, wherein the liquid inlet 12 is connected to the liquid storage chamber 50, and the liquid outlet 13 is connected to the first buffer portion 31. The liquid storage chamber 50 stores the aforementioned aerosol generating substrate, and the aerosol generating substrate can enter the first buffer portion 31 of the atomizing assembly in a timely and quantitative manner through the liquid flow pump 11.

[0074] Furthermore, the first buffer section 31 may be any liquid storage or liquid conducting structure known in the prior art, such as a fiber-shaped, sponge-shaped, or sintered porous body, which may play the role of buffering the aerosol generating matrix.

[0075] Furthermore, the aerosol generating device also includes a battery component for providing power to the control component, the atomization component, the liquid delivery component, etc.

[0076] Furthermore, the atomization component can be atomized by vibration or by heating.

[0077] Furthermore, the aerosol generating device further includes a second driving component. When the working mode of the atomizing element 32 is heating atomization, the second driving component is a DC voltage conversion unit, which can increase or decrease the battery voltage of the atomizing element 32 to ensure the operation of the atomizing element 32. When the working mode of the atomizing element 32 is vibration atomization, the second driving component is an alternating voltage conversion unit, which can convert the battery voltage into an alternating voltage.

[0078] In a preferred embodiment of the present invention, the first buffer portion 31 is a porous ceramic, the porous ceramic includes a first end and a second end, the first end of the porous ceramic is connected to the liquid outlet 13 of the flow pump 11, and the second end of the porous ceramic is inlaid with an atomizing element 32. Compared with the traditional atomizing structure of winding a heating wire on a glass fiber rope, the volume of the porous ceramic can be set larger to cache more aerosol-generating substrates. The atomizing element 32 can be a heating atomizing element, such as a resistance heating element or an electromagnetic heating element.

[0079] Furthermore, a second buffer portion is included, which is arranged between the liquid delivery component and the first buffer portion 31 and is used to better buffer the aerosol generating matrix.

[0080] In a preferred embodiment, Figures 4 to 6 As shown, the second buffer portion is a flexible buffer portion 20, which is made of a flexible buffer material, such as organic cotton, sponge, etc. Compared with porous ceramics, the flexible buffer material can absorb and transfer the aerosol-generating matrix delivered by the liquid delivery component faster, quickly and effectively buffer the aerosol-generating matrix, avoid leakage and dry burning, and the flexible buffer material does not contact the atomizing element 32, and will not produce adverse odors when heated.

[0081] Furthermore, the flexible buffer portion can be arranged side by side with the porous ceramic; or the second buffer portion can be embedded in the first end of the first buffer portion. Figures 4 to 6 As shown, the liquid outlet 13 of the flow pump 11 is in direct contact with the flexible buffer portion 20. Compared with porous ceramics, the flexible buffer material can absorb and transfer the aerosol generating matrix delivered by the liquid delivery component more quickly, quickly and effectively cache the aerosol generating matrix, and avoid leakage and dry burning.

[0082] In another preferred embodiment, Figure 7 to Figure 9 As shown, the second buffer part is a buffer tank 40, which is arranged at the first end of the porous ceramic. The upper end of the buffer tank 40 is open, and the liquid outlet 13 of the flow pump 11 is inserted into the buffer tank 40 from the opening, and the opening is closed to prevent the aerosol-generating matrix from seeping out at the matching point of the liquid outlet 13 of the flow pump 11 and the buffer tank 40, resulting in leakage. A buffer cavity 41 is also left at the bottom of the buffer tank 40. The aerosol-generating matrix transferred by the flow pump 11 can be buffered in the buffer cavity 41, thereby increasing the buffer amount of the aerosol-generating matrix in the atomization component and preventing leakage.

[0083] Furthermore, the aerosol generating device further comprises a first driving assembly, through which the amount of aerosol generating substrate transmitted by the flow pump 11 to the atomizing assembly is precisely controlled.

[0084] Furthermore, when the flow pump 11 is a piezoelectric pump, the first drive component is an AC voltage conversion unit, which is used to convert the battery voltage of the piezoelectric pump into an AC voltage; when the liquid delivery component is a peristaltic pump, the first drive component is a DC voltage conversion unit, which is used to control the battery voltage of the peristaltic pump and further control the rate at which the flow pump 11 delivers the aerosol generating device.

[0085] In summary, by using the aerosol generating device described in the present invention, the control component controls the liquid delivery component to actively deliver oil, which effectively avoids oil leakage and oil explosion; and the time for the liquid delivery component to deliver the aerosol generating matrix is ​​longer than the working time of the atomization component, which can ensure that the atomization component is adequately supplied with oil to avoid dry burning.

[0086] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
