The aerosol generating substrate 102 can be a liquid and solidifiable atomization substrate processed from leaves and / or stems of plants (e.g., tobacco), propylene glycol, glycerol, artificial flavors, water, and other support materials, and can also be a paste-shaped atomization medium or a solid atomization substrate. The aerosol generating substrate can be covered with an auxiliary material on one side or both sides in the thickness direction. The auxiliary material can be a plant fiber base material (such as cardboard, oil-proof paper, etc.), a polymer base material (such as plastic, etc.), a metal material, an inorganic non-metallic material (such as ceramic, quartz, etc.), and the like.

In some embodiments, the outer conductor unit 10 comprises a first side wall 111 formed by the first cover plate 11 and a second side wall 121 formed by the second cover plate 12, and the second side wall 121 is arranged opposite to the first side wall 111.

[0050] Further, in some embodiments, the second cover plate 12 is made of metal plate, further, in some embodiments, the second cover plate 12 is made of metal plate or other high-conductivity material, for example, the second cover plate 12 is made of gold, silver, copper, aluminum, iron, gold-containing alloy, aluminum-containing alloy, copper-containing alloy, iron-containing alloy, stainless steel, etc., or the second cover plate 12 is formed by setting a metal coating on the surface of a non-metal cover plate.

[0051] The second cover plate 12 is substantially rectangular in longitudinal section, and can be detachably connected with the first cover plate 11. In some embodiments, the second cover plate 12 can be connected with the first cover plate 11 by setting a screw connection structure. In other embodiments, the second cover plate 12 can also be connected with the first cover plate 11 by setting a clamping structure. In other embodiments, the first cover plate 11 and the second cover plate 12 can be integrally formed. The first cover plate 11 and the second cover plate 12 can shield electromagnetic waves, and can define a nearly closed cavity. The second side wall 121 is provided with a second accommodating groove 122, and the second accommodating groove 122 is polygonal or other shapes in longitudinal section, and in some embodiments, the second accommodating groove 122 can be quadrangular. The second accommodating groove 122 can be used to form the accommodating cavity 14. The second accommodating groove 122 is provided with a second notch 123 on one side, and the second notch 123 and the first notch 115 are mutually spliced to form a passage for installing the air outlet pipe 103. The second side wall 121 is provided with a through hole 124, which can be provided through the thickness direction of the second side wall 121 and communicated with the second accommodating groove 122. The through hole 124 can be provided at the central axis of the second side wall 121.

[0052] As shown in FIG. 3 and FIG. 8, in some embodiments, the partition 13 can be a metal plate, further, in some embodiments, the partition 13 is made of metal plate or other high-conductivity material, for example, the partition 13 is made of gold, silver, copper, aluminum, iron, gold-containing alloy, aluminum-containing alloy, copper-containing alloy, iron-containing alloy, stainless steel, etc., or the partition 13 is formed by setting a metal coating on the surface of a non-metal cover plate.

[0053] In some embodiments, the partition 13 is in the shape of a rectangular plate, and the shape and size of the partition 13 are adapted to the shape and size of the first accommodating groove 112. Specifically, in some embodiments, the partition 13 is substantially rectangular, and in other embodiments, the partition 13 can not be limited to be rectangular. In some embodiments, a through hole 131 is arranged between the accommodating cavity 113 and the accommodating cavity 14, and specifically, the through hole 131 is arranged on the partition 13, the through hole 131 is used to communicate the accommodating cavity 113 and the accommodating cavity 14, and the inner conductor unit 20 can be partially installed in the through hole 131. In some embodiments, the through hole 131 can be a strip-shaped hole, and is substantially elliptical, and in other embodiments, the through hole 131 can be rectangular or other shapes. In other embodiments, the partition 13 can be integrally formed with the first cover plate 11 or the second cover plate 12.

[0054] As shown in FIGS. 2, 3 and 9, in some embodiments, the inner conductor unit 20 can include a radiation portion 21 for radiating electromagnetic energy. The radiation portion 21 is arranged on one side of the accommodating cavity 14, and is in the shape of a long strip, and can be longitudinally arranged along the length direction of the through hole 131. Specifically, in some embodiments, the radiation portion 21 can be arranged on the side of the accommodating cavity 14 opposite to the wide surface 1020 of the aerosol generating substrate 102. The cross section of the radiation portion 21 is substantially square, and of course, it can be understood that in other embodiments, the cross section of the radiation portion 21 can also be circular. The extension direction of the radiation portion 21 is perpendicular to the thickness direction of the aerosol generating substrate 102, and the thickness direction is perpendicular to the radial direction or the width direction of the aerosol generating substrate 102, that is, the radiation portion 21 is parallel to the radial direction of the aerosol generating substrate 102. The longitudinal surface of the radiation portion 21 can be arranged towards the accommodating cavity 14. When the rotation shaft 30 drives the aerosol generating substrate 102 to rotate, the aerosol generating substrate 102 can rotate relative to the radiation portion 21, and the radiation portion 21 can traverse the surface of the aerosol generating substrate 102, that is, the radiation portion 21 is arranged opposite to the wide surface of the aerosol generating substrate 102, and when the aerosol generating substrate 102 rotates by a set angle, the radiation portion 21 can traverse a small range of orientation to heat, and the traversal strategy includes sequentially traversing, fixed or non-fixed interval traversing, etc., so as to ensure that each heating is uniform heating, and further to ensure the consistency of the aerosol.

[0055] The principle of microwave heating is generally based on the design of a quarter-wave coaxial cavity with an open end of the inner conductor unit 20. After the aerosol generating article 100 is added, the accommodating cavity 14 will resonate at the resonance frequency, thereby achieving rapid heating of the aerosol generating substrate 102 in the aerosol generating article 100. The thickness of the aerosol generating substrate 102 is greater than or equal to the radiation depth (effective heating depth) of the radiation portion 21 of the aerosol generating device, and specifically, the thickness of the aerosol generating substrate 102 can be slightly greater than the radiation depth of the radiation portion 21, thereby ensuring good substrate utilization.

[0056] In some embodiments, the inner conductor unit 20 further comprises an impedance matching portion 22, which can be bent with the radiation portion 21, and the cross-sectional shape and size of the impedance matching portion 22 can be adapted to the cross-sectional shape and size of the inner conductor unit 20. The impedance matching portion 22 comprises a first impedance matching segment 221 and a second impedance matching segment 222. The first impedance matching segment 221 is connected with one end of the radiation portion 21 and is bent with the radiation portion 21, and can be arranged at a set angle with the radiation portion 21, which can be an acute angle or a right angle. The second impedance matching segment 222 can be connected with the first impedance matching segment 221 and is bent, and the second impedance matching segment 222 is arranged parallel to the radiation portion 21. The bent arrangement is beneficial to avoid unnecessary heating of the aerosol generating substrate area, thereby ensuring consistent heating area each time. In some embodiments, the distance from the second impedance matching segment 222 to the accommodation cavity 14 is greater than the distance from the radiation portion 21 to the accommodation cavity 14, thereby improving the accuracy of the heating range and avoiding heating of non-heating areas.

[0057] In some embodiments, the inner conductor unit 20 can further comprise a limiting portion 23 connected with the second impedance matching segment 222, and the cross-sectional size of the limiting portion 23 can be greater than that of the second impedance matching segment 222. In some embodiments, the limiting portion 23 can be substantially cylindrical, and the radial dimension of the limiting portion 23 is greater than the maximum width of the second impedance matching segment 222. The radial dimension of the limiting portion 23 is greater than the radial dimension of the connecting through hole 1111, and thus can be used for installation and limiting of the inner conductor unit 20.

[0058] In some embodiments, the inner conductor unit 20 further comprises a connecting portion 24 arranged at the end of the limiting portion 23 away from the impedance matching portion 22, which can be inserted into the connecting through hole 1111 and can be tightly fitted, such as interference fitted, with the connecting through hole 1111. The inner conductor unit 20 is connected with the first side wall 111 of the outer conductor unit 10 through the connection of the connecting portion 24 and the connecting through hole 1111.

[0059] In some embodiments, the rotation shaft 30 is arranged opposite to the inner conductor unit 20 and is connected with the center of the aerosol generating substrate 102 in the accommodation cavity 14. Specifically, the rotation shaft 30 can pass through the through hole 124 into the accommodation cavity 14 and pass through the through hole 1013 of the aerosol generating article 100 to be connected with the center of the aerosol generating substrate 102. In some embodiments, the rotation shaft can be a metal material, such as gold, silver, copper, aluminum, iron, gold-containing alloy, aluminum-containing alloy, copper-containing alloy, iron-containing alloy, stainless steel, etc. In other embodiments, the rotation shaft 30 can also be a non-metal material, such as plastic.

[0060] In some embodiments, the aerosol generating device further comprises a power unit (not shown) which can be connected with the rotating shaft 30 to drive the rotating shaft 30 to rotate. In some embodiments, the power unit (not shown) can comprise an electric mechanism such as a motor, and can be connected with the rotating shaft 30 through a connecting transmission mechanism or directly connected with the rotating shaft 30. In other embodiments, the power unit (not shown) can also be a manual mechanism which can be connected with the rotating shaft 30 through a connecting structure or a transmission mechanism.

[0061] In some embodiments, the aerosol generating device further comprises a microwave feeding unit 40 which can be installed at the mounting hole 116 and connected with the inner conductor unit 20 to feed microwaves to the inner conductor unit 20. The microwaves are reflected and superimposed at the radiation part 21 of the inner conductor unit 20 to form a standing wave field to quickly heat the aerosol generating substrate 102 to generate aerosols. Compared with conventional conduction heating, the microwave heating mode can better meet the user's demand for "zero waiting" and almost no waiting is needed to enjoy the fun of atomization.

[0062] The design of the aerosol generating device based on the sheet-shaped aerosol generating substrate 32 has three great benefits:

[0063] (1) By rotating to traverse the small area of the sheet-shaped aerosol generating substrate 32, a large number of puffs can be achieved while heating to generate aerosols with good consistency. Specifically, the large number of puffs can be more than fourteen, such as fourteen, eighteen, twenty, etc.

[0064] (2) As can be seen from FIG. 10, the aerosol generating device of the present application has better heating focusing; as can be seen from FIG. 11, the feeding efficiency of the working frequency is higher.

[0065] (3) The utilization rate of the aerosol generating substrate 102 is improved, and after the aerosol generating substrate 102 rotates around the center for one revolution, almost all areas of the surface will be traversed.

[0066] It can be understood that the above embodiments only express the preferred embodiments of the present application, which are described in detail and specifically, but cannot be understood as a limitation on the scope of the patent of the present application; it should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and some deformations and improvements can be made, which all belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application shall belong to the scope of the claims of the present application.
