[0029] Figure 1The first embodiment of the aerosol generating system of the present invention is shown. The aerosol generating system includes an aerosol generating device 100 and an aerosol generating substrate 200. The aerosol generating device is used to heat the aerosol generating substrate 200 to generate an aerosol for the user to inhale. The aerosol generating substrate 200 is at least partially loaded into the aerosol generating device, and can generate an aerosol in a heated state. In some embodiments, the aerosol generating substrate 200 is columnar, specifically, the aerosol generating substrate 200 can be cylindrical, and can be a solid material in the form of a silk strip or a sheet made from leaves and / or stems of plants. Of course, it can be understood that in some other embodiments, the aerosol generating substrate 200 is not limited to a columnar shape, and can be a sheet or block shape. In some embodiments, the aerosol generating substrate 200 is also not limited to a solid material, and can also be a liquid atomization matrix.

[0030] like Figure 1 and Figure 2 As shown, in the present embodiment, the aerosol generating device 100 further includes a housing 10, an atomizing structure 20, a heating structure 30, a fuel supply mechanism 40 and an ignition structure. The housing 10 can be used to accommodate the atomizing structure 20, the heating structure 30, the fuel supply mechanism 40, etc. The atomizing structure 20 is arranged in the housing 10, and is used to accommodate at least part of the aerosol generating matrix 200. The heating structure 30 is spaced and arranged relatively to the atomizing structure 20, so as to achieve heating of the aerosol generating matrix 200 by heating the atomizing structure 20 to generate an aerosol. The fuel supply mechanism 40 can supply fuel to the heating structure 30, and in some embodiments, the fuel can be a gaseous fuel, such as methane. In some embodiments, the fuel can also be a liquid fuel, such as alcohol. In the present embodiment, the fuel supply mechanism 40 can be opened or closed by electric drive, thereby improving the simplicity of operation and the user experience. The ignition structure may be disposed toward the heating structure 30 , and may ignite the fuel while the fuel supply mechanism 40 supplies fuel to the heating structure 30 , thereby heating the atomization structure 20 , thereby achieving heating of the aerosol generating substrate 200 .

[0031] In the present embodiment, the atomizing structure 20 may include a first barrel 21 and a second barrel 22. The first barrel 21 and the second barrel 22 may be coaxially arranged, the first barrel 21 may be located at one end of the second barrel 22, the first barrel 21 and the second barrel 22 may be interconnected, and may be connected to form a component. The second barrel 22 is arranged near the heating structure 30, and an end wall 221 is arranged at one end thereof opposite to the heating structure 30. In the present embodiment, the aerosol generating device 100 also includes an atomizing chamber 23, which is formed in the first barrel 21 and the second barrel 22, and can be partially loaded with the aerosol generating substrate 200. When the heating structure 30 heats the barrel wall of the second barrel 22 of the atomizing structure 20, the heat generated by the heating structure 30 can be conducted to the atomizing chamber 23 through the barrel wall of the second barrel 22, thereby heating the aerosol generating substrate 200 located in the atomizing chamber 23, so that it generates an aerosol for the user to inhale. In some embodiments, the atomizing chamber 23 can be connected to the suction port by connecting to an aerosol output pipe. In some embodiments, the atomizing chamber 23 can also be connected to the outside by connecting to an air intake pipe, and the external gas can be transported to the atomizing chamber 23 through the air intake pipe, and the aerosol generated in the atomizing chamber 23 can be transported to the suction port through the aerosol output pipe for the user to inhale.

[0032] In this embodiment, the heating structure 30 can be a cup body structure, a combustion chamber 31 can be formed inside, and an opening 32 connected to the combustion chamber 31 is provided at one end. The opening 32 can be set toward the atomization structure 20, and the flame ejected from the combustion chamber 31 can be ejected from the opening 32.

[0033] In this embodiment, the fuel supply mechanism 40 may include a fuel storage structure 41 and a fuel supply switch 42. In some embodiments, the fuel storage structure 41 may be a tank, such as a gas tank. The fuel supply switch 42 may be disposed at the fuel outlet of the fuel storage structure 41. In some embodiments, the fuel supply switch 42 may be a valve structure, such as a deflation valve, which may be opened by prying. In some embodiments, the fuel supply switch 42 may not be limited to a valve structure.

[0034] In the present embodiment, the aerosol generating device 100 further includes a driving mechanism 50. The driving mechanism 50 is an electric driving mechanism, which can be opened or closed by an electric driving fuel supply mechanism. By setting the driving mechanism, the fuel supply mechanism can be opened or closed without manually pressing the fuel supply switch, thereby improving the user experience. The driving mechanism 50 is synchronously arranged with the fuel supply mechanism 40 and the ignition structure, that is, the driving mechanism 50 can be opened synchronously with the fuel supply mechanism 40 and the ignition structure. In some embodiments, the driving mechanism 50 is not only opened synchronously with the fuel supply mechanism 40 and the ignition structure, but also can be closed synchronously. When the driving mechanism 50 is turned on, the fuel supply mechanism 40 and the ignition structure are opened synchronously. When the fuel supply mechanism 40 is in the open state, the fuel supply mechanism 40 can supply fuel to the combustion chamber 31, that is, the fuel supply switch 42 is turned on, and the fuel in the fuel storage structure 41 can be sprayed toward the combustion chamber 31, and the ignition structure ignites the fuel in the combustion chamber 31. When the fuel supply mechanism 40 is in the closed state, the fuel supply mechanism stops supplying fuel to the combustion chamber 31, that is, the fuel supply switch 42 is closed, and the ignition structure is closed at the same time. In some embodiments, the ignition structure can also be automatically closed after the fuel in the combustion chamber 31 is ignited. In some embodiments, the stopping of the fuel supply mechanism 40 and the closing of the drive mechanism 50 can also be set asynchronously. For example, after the fuel supply mechanism 40 is opened, the drive mechanism 50 can drive the fuel supply mechanism 40 to open when it is opened for the first time, and then it can be closed. The drive mechanism 50 drives the fuel supply mechanism 40 to close when it is opened for the second time, and then closes again.

[0035] In the present embodiment, the driving mechanism 50 may include an operating rod 51 and a driving assembly 52 that cooperates with the operating rod 51. The operating rod 51 is movably arranged. In the present embodiment, the operating rod 51 can operate the opening or closing of the fuel supply switch 42 based on the lever principle. Specifically, the operating rod 51 can pry the air release valve to open the air release valve. In the present embodiment, when the operating rod 51 is located at the first position, the fuel supply switch 42 is opened, and when the operating rod 51 is located at the second position, the fuel supply switch 42 is closed. The driving assembly 52 can be connected to the operating rod 51 to drive the operating rod 51 to move. The first position and the second position can be defined by the stroke of the fuel supply switch 42 when the fuel supply switch 42 is opened, such as the stroke of the valve stem of the air release valve.

[0036] In this embodiment, the operating rod 51 may include a first rod body 511 and a second rod body 512, wherein the second rod body 512 may be disposed at one end of the first rod body 511 and cooperate with the driving assembly 52, and the end of the first rod body 511 away from the second rod body 512 may extend to the fuel supply switch 42. In this embodiment, the first rod body 511 at least includes a first portion 511a and a second portion 511c connected to the first portion 511a; the first portion 511a may extend to the fuel supply switch 42, and the fuel supply switch 42 may be pried under the downward pressure of the second portion 511c, thereby opening the fuel supply switch 42. The connection between the first portion 511a and the second portion 511c forms a fulcrum 511c, and the fulcrum 511c may be against the fuel storage structure 41. In some embodiments, the first rod 511 further includes a third portion 511d, which is connected to an end of the second portion 511c away from the first portion 511a and is bent with the second portion 511c. The second rod 512 can be installed on the third portion 511d along a length direction perpendicular to the third portion 511d.

[0037] In the present embodiment, the driving assembly 52 may include a driving motor 521, a screw rod and a slider 522. The driving motor 521 may be a conventional motor, such as a servo motor, a stepping motor, etc. The driving motor 521 may be set to rotate in a forward and reverse manner. The screw rod may be connected to the output shaft of the driving motor 521 and driven to rotate by the driving motor 521. The slider 522 may be sleeved on the screw rod and screwed with the screw rod. When the screw rod rotates, the slider 522 may be driven to move along the length direction of the screw rod. The length direction of the screw rod may be perpendicular to the length direction of the operating rod 51. The slider 522 is connected to the operating rod 51. When the driving motor 521 rotates forward, the slider 522 drives the third part 511d to move in the direction of the fuel storage structure 41, and the first part 511a of the operating rod 51 may move in the direction of the atomization structure 20, thereby prying the fuel supply switch 42 to open the fuel supply switch 42. When the driving motor 521 is reversed, the slider 522 drives the third part 511d to move away from the fuel storage structure 41, and the first part 511a of the operating rod 51 can move toward the fuel storage structure 41, thereby closing the fuel supply switch 42, so that the flame of the combustion chamber is extinguished and the combustion stops. In some other embodiments, the driving assembly 52 is not limited to including the driving motor 521, the screw rod and the slider 522. In some embodiments, the fuel supply amount can be adjusted by the forward and reverse rotation of the driving motor 521.

[0038] In this embodiment, the ignition structure can select a conventional ignition switch, which can realize ignition by pulse ignition. When the fuel is sprayed, the ignition structure is opened to ionize the air, generate arc sparks, and then ignite the fuel in the combustion chamber 31, and can be closed after the fuel is ignited. It can be understood that in some other embodiments, the ignition structure can also be formed by piezoelectric ceramics.

[0039] In this embodiment, the aerosol generating system of the present invention can generate aerosol as follows: Figure 3 As shown:

[0040] First, the aerosol generating substrate 200 may be assembled to the aerosol generating device 100 . Specifically, the medium segment of the aerosol generating substrate 200 may be inserted into the atomizing chamber 23 .

[0041] The driving mechanism 50 is turned on. In some embodiments, a button electrically connected to the driving mechanism 50 can be set on the housing 10, and the driving mechanism 50 can be triggered to open or close by pressing the button. When the driving mechanism 50 is turned on, the driving mechanism 50 can drive the fuel supply mechanism 40 to open. Specifically, the driving mechanism 50 drives to open the fuel supply switch 42, and the fuel supply mechanism 40 supplies fuel to the combustion chamber. At the same time, the ignition switch is turned on to ignite the fuel in the combustion chamber 31. When the ignition is successful in the combustion chamber 31, the fuel combustion generates heat, and the switch can be turned off. If the ignition is unsuccessful, the ignition operation can be timed. If it is timed out, the system can issue an abnormal reminder. After the ignition is successful, the temperature of the atomizing chamber 23 can be monitored in real time. When the atomizing chamber 23 reaches the set temperature, the aerosol generating matrix 200 generates an aerosol, which can be inhaled by the user. If the temperature in the atomizing chamber 23 does not reach the preset temperature, the atomizing chamber 23 can be heated and timed. When the heating time exceeds the set time, it can be determined that an aerosol is generated, and the user can inhale the aerosol. When the puffing is finished, the user can pull out the aerosol generating substrate 200. If another puffing is needed, the above operation can be repeated.

[0042] Figure 4A second embodiment of the aerosol generating system of the present invention is shown, which differs from the first embodiment in that the driving component 52 may include an electromagnetic structure 523, which may be located in a direction perpendicular to the length of the operating rod 51. Specifically, it may be arranged opposite to the second rod body 512. When the electromagnetic structure 523 is in a powered-on state, it may be attracted to the operating rod 51, that is, attracted to the second rod body 512, and then may drive the third part 511d of the operating rod 51 to move in the direction of the electromagnetic structure 523, so that the first part 511a of the operating rod 51 moves in the direction of the fuel storage structure 41. When the electromagnetic structure 523 is in a powered-off state, the second rod body 512 may be released, and the third part 511d of the operating rod 51 may move away from the electromagnetic structure 523, so that the first part 511a of the operating rod 51 moves away from the fuel storage structure 41 until the operating rod 51 and the electromagnetic structure 523 are spaced apart, thereby opening the fuel supply mechanism 40.

[0043] Figure 5 The third embodiment of the aerosol generating system of the present invention is shown, which is different from the first embodiment in that a cam structure 524 can be used to replace the screw and the slider. The cam structure 524 can be connected to the output shaft of the drive motor 521, and the drive motor 521 can drive the cam structure 524 to rotate. In this embodiment, the cam structure 524 can be arranged in linkage with the operating rod 51. When the cam structure 524 is in the far repose angle state, the operating rod 51 is in the first position, that is, the third part 511d is driven by the convex part of the cam structure 524 to move toward the direction close to the fuel storage structure 41, the first part 511a moves toward the heating structure 30, and the fuel supply switch 42 is turned on. When the cam structure 524 is in the near repose angle, the operating rod 51 is in the second position, that is, the third part 511b moves away from the fuel storage structure 41, the first part 511a moves away from the heating structure 30, and the fuel supply switch 42 is turned off.

[0044] In some other embodiments, a gear set may be used to replace the screw rod and the slider, and the gear set may include at least a driving wheel and a driven wheel. The driving wheel may be connected to the output shaft of the driving motor 521, and the driving motor 521 may drive the driving wheel to rotate. The driven wheel is connected to the operating rod 51, specifically, it may be connected to the second rod body 512, the second rod body 512 may be arranged non-coaxially with the driven wheel, the second rod body 512 may be connected to the periphery of the rotation center of the driven wheel, and mesh with the driving wheel. When the driving wheel rotates, it may drive the driven wheel to rotate. In addition, the second rod body 512 of the operating rod 51 may be driven to move closer to or away from the fuel storage structure 41, thereby realizing the opening or closing of the fuel supply switch 42.

[0045] In some other embodiments, the driving mechanism may further include a locking structure, which may cooperate with the operating rod 51, specifically, may cooperate with the second rod body 512 of the operating rod 51, so that the second rod body 512 has a self-locking function. By providing the locking structure, when the driving assembly 52 presses the second rod body 512 in the direction of the fuel storage structure 41, the second rod body 512 may be locked in a set position, at which time, the driving assembly 52 is no longer subjected to the force of the second rod body 512, and the driving assembly 52 is separated from the second rod body 512. When the driving assembly 52 contacts the second rod body 512 again and presses the second rod body 512 again, the second rod body 512 may be restored to the state before being locked. The driving assembly 52 may be separated from the second rod body 512 again, the second rod body 512 is not subjected to the pressure of the driving assembly 52, and the fuel supply switch 42 is closed.

[0046] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention.
