Currently, an aerosol generating device is widely popular on the market, and a heating manner of the aerosol generating device is continuously improved. A microwave heating technology gradually becomes mainstream. However, in the related technology, an inner conductor and an outer conductor in a microwave resonant cavity are not easily disassembled, and a vaporized aerosol condenses on a surface of the inner conductor, which causes dirt to be formed over a long time, affecting inhalation taste, and even endangering human health. To resolve this problem, an aspect of this disclosure provides an aerosol generating device 100 and an aerosol generating system 1000 (shown in FIG. 1).

Referring to FIG. 1, according to a first aspect, this disclosure provides an aerosol generating device 100. The aerosol generating device 100 includes a conductor assembly 10 and a microwave assembly 30. The conductor assembly 10 includes a first conductor 11 and a second conductor 13 that can conduct electricity. The first conductor 11 and the second conductor 13 are detachably combined and jointly form a resonant cavity 15, the resonant cavity 15 includes at least a heating region 151, and the heating region 151 is used to heat an aerosol generating article 300. The microwave assembly 30 is configured to feed a microwave into the resonant cavity 15, and an aerosol generating substance 303 in the aerosol generating article 300 absorbs the microwave and is heated to generate an aerosol.

Specifically, the aerosol generating device 100 is a structure in which the aerosol generating substance 303 in the aerosol generating article 300 is acted through microwave heating to generate an aerosol. The aerosol may be visible or invisible and may include vapor (for example, fine particulate matter in a gas state that is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol generating substance 303 is a plant leaf product that has been processed and heated to generate an aerosol. A form of the aerosol generating substance 303 may be liquid, full solid, or semi solid. When the aerosol generating substance 303 is in a liquid state, the aerosol generating substance 303 may be e-liquid. When the aerosol generating substance 303 is in a full solid state, the aerosol generating substance 303 may be tobacco or flower. When the aerosol generating substance 303 is in a semi solid state, the aerosol generating substance 303 may be a thick paste. In this disclosure, an example in which the aerosol generating substance 303 is a paste shown in FIG. 1 or FIG. 10 is used for description.

The conductor assembly 10 is a structure configured to form the resonant cavity 15, shield and confine a microwave in the resonant cavity 15, and also load another element. In this disclosure, the conductor assembly 10 is configured to load the aerosol generating article 300, and enable the aerosol generating substance 303 in the aerosol generating article 300 to be heated by using the microwave in the resonant cavity 15 to generate an aerosol. The first conductor 11 and the second conductor 13 of the conductor assembly 10 are detachably mounted. The detachable mounting may be, but is not limited to, a threaded connection, a magnetic attraction connection, a buckle connection, or the like.

The microwave assembly 30 is an assembly configured to generate a microwave. The microwave is an electromagnetic wave with a frequency of 300 MHz to 300 GHz (with a wavelength of 1 meter to 1 millimeter), which has some properties of visible light and is propagated in a straight line. The microwave can be reflected when encountering with a conductive material, may penetrate through an insulating material such as glass, plastic, or ceramic, and may be absorbed when encountering a medium such as protein containing water, fat, and the aerosol generating substance 303, and electromagnetic energy of the microwave is converted into thermal energy. In this disclosure, the microwave assembly 30 is configured to feed the microwave into the resonant cavity 15. The microwave is reflected and propagated in the resonant cavity 15, and is absorbed by the aerosol generating substance 303, and the aerosol generating substance 303 is heated to generate an aerosol.

In the aerosol generating device 100 of this disclosure, the microwave assembly 30 feeds the microwave into the resonant cavity 15 jointly formed by the first conductor 11 and the second conductor 13, to heat the aerosol generating substance 303. The first conductor 11 and the second conductor 13 are easily disassembled and separated, to facilitate cleaning of the resonant cavity 15, and greatly reduce or even avoid dirt remaining in the resonant cavity 15, thereby ensuring good inhalation taste and maintaining health and safety of a human body, and further reducing energy consumption.

In addition, in the field of vaporization technologies, the aerosol generating device generally heats the aerosol generating substance in a resistive heating manner. Specifically, A heating member such as a resistance wire or a coil is heated by using a power supply, and the heating member transfers heat to the aerosol generating substance to generate an aerosol.

However, in the resistive heating manner, the heating member such as the resistance wire or the coil needs to be arranged, and processing is relatively troublesome. In addition, in a transportation or use process, the heating member falls off due to a problem such as falling or a collision. In addition, the heating member such as the resistance wire or the coil is prone to over-temperature. Once over-temperature occurs, the aerosol generating substance (especially, e-liquid) is prone to produce harmful substances due to high temperature cracking, which causes a safety problem. Moreover, in the resistive heating manner, a temperature field is uneven, a low-temperature non-vaporization region exists, a vaporization process is non-whole vaporization, and vaporization consistency is not good. Moreover, the heating member is in contact with the aerosol generating substance for a long time, and there is a risk of contamination, which affects inhalation taste.

In this disclosure, the aerosol generating device 100 adopts a microwave heating manner. The aerosol generating substance 303 absorbs a microwave to generate an aerosol, without the heating member such as the resistance wire or the coil. Therefore, compared with the resistive heating manner, there is no risk that the heating member such as the resistance wire or the coil falls off, there is no risk that harmful substances are formed due to over-temperature of the heating member, and there is no risk that the heating member is in contact with the aerosol generating substance for a long time to cause contamination. In addition, because the microwave is concentrated in the heating region 151 of the resonant cavity 15, different from heat conduction, the aerosol generating substance 303 absorbs the microwave to generate thermal energy to generate an aerosol. Compared with the resistive heating manner, integrity and consistency of the microwave vaporization heating manner are relatively good. Further, the aerosol generating substance 303 may automatically absorb the microwave to generate thermal energy. In a heating process, the conductor assembly 10 does not actively generate heat. Compared with resistive heating, microwave heating can effectively reduce a temperature of a surface of the aerosol generating device 100.

The aerosol generating device 100 is further described below with reference to the accompanying drawings.

A cavity wall of the resonant cavity 15 has a conductive property and can form a conduction shielding layer, to avoid diffusion of the microwave to an external environment. The coaxial resonant cavity 15 can ensure that the microwave transferred inside the resonant cavity 15 may be transmitted into the aerosol generating substance 303 to be absorbed by the aerosol generating substance 303, to ensure heating uniformity of the aerosol generating substance 303. In some embodiments, the coaxial resonant cavity 15 may be a quarter-wave coaxial resonant cavity 15, that is, a length of the resonant cavity 15 is a quarter wavelength in a microwave transmission direction.

The aerosol generating system 1000 includes the aerosol generating device 100 according to any one of the foregoing embodiments and an aerosol generating article 300. The aerosol generating article 300 is loaded in the resonant cavity 15, and the second conductor 13 at least partially extends into the aerosol generating article 300.

With reference to FIG. 2, in some aspects, the aerosol generating article 300 includes a loading member 301 and an aerosol generating substance 303. The loading member 301 is detachably loaded in the resonant cavity 15, and one end of the second conductor 13 extends into the loading member 301. The aerosol generating substance 303 is loaded in the loading member 301, and the aerosol generating substance 303 is located in the heating region 151.

Preferably, a specific gap is reserved between one end of the second conductor 13 extending into the loading member 301 and the aerosol generating substance 303. Further, the loading member 301 is made of a microwave low-loss material. A microwave high-loss material 500 is arranged in the aerosol generating substance 303. A porous ceramic material 500 is arranged in the aerosol generating substance 303.

Specifically, the aerosol generating article 300 is configured to be placed in the aerosol generating device 100 and be heated by using a microwave to generate an aerosol required by a user. The aerosol generating substance 303 is loaded in the loading member 301. The aerosol generating substance 303 absorbs microwave energy, and high-frequency friction and collision occur on a polar molecule inside the aerosol generating substance 303, so that thermal energy is generated. After a boiling point of the aerosol generating substance 303 is reached, the aerosol generating substance 303 starts to be vaporized, to form an aerosol. The aerosol generating substance 303 is spaced apart from the second end 1333 of the inner conductor 133, to avoid a case that during inhalation of a user, the second end 1333 of the inner conductor 133 is blocked by the aerosol, the aerosol or air cannot enter/exit from the channel 1335 of the inner conductor 133.

The loading member 301 is configured to load the aerosol generating substance 303. In addition, the vaporized aerosol condenses on an inner wall of the loading member 301 and may return to a vaporization region to be re-vaporized, to reduce a loss.

The loading member 301 may be loaded at a central position of the resonant cavity 15 or at another position in the resonant cavity 15. The microwave low-loss material is a non-polar material, and is hardly heated by using energy of the microwave. The microwave low-loss material includes, but is not limited to, ceramic, glass, a high-polymer material, and the like. The high-polymer material may be, for example, polyethylene, polypropylene, or Teflon. Therefore, when the aerosol generating substance 303 absorbs a microwave to generate heat, an outer side of the loading member 301 hardly heats up, thereby effectively reducing a temperature on a surface of the housing 90. The microwave high-loss material 500 is used to absorb a microwave to generate heat, providing the heat to the aerosol generating substance 303, and providing a disturbance effect on a liquid state, to improve vaporization efficiency. The microwave high-loss material 500 may be, but is not limited to, a metal, a carbon material, silicon carbide, or the like. A form of the microwave high-loss material 500 may be a sheet, a rod, a ball, a barrel, a mesh, or the like. The porous ceramic material 500 has good chemical stability and can tolerate a high temperature. The porous ceramic material 500 is used to make vaporization of the aerosol generating substance 303 more violently and uniformly, which can effectively improve vaporization efficiency. The porous ceramic material 500 may be, but is not limited to, a porous ceramic sheet, a porous ceramic rod, a porous ceramic ball, a porous ceramic barrel, a porous ceramic mesh, or the like.

Still referring to FIG. 1 and FIG. 2, when a vaporized aerosol needs to be obtained, the aerosol generating substance 303 may be loaded into the loading member 301, and placed into the resonant cavity 15. The inner conductor 133 of the second conductor 13 is inserted into the aerosol generating article 300, and the first conductor 11 is in a sealed connection with the second conductor 13. The power supply unit 70 provides electric energy, and the control assembly 50 controls the microwave assembly 30 to feed a microwave into the resonant cavity 15. The aerosol generating substance 303 absorbs the microwave to generate heat, and performs vaporization, to generate an aerosol. During inhalation, air enters the resonant cavity 15 through the air inflow passage. In addition, the aerosol is absorbed through the aerosol outflow passage.
