[0041] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "locked" to another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0042] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0043] Please see Figures 1-3This application provides an aerosol generating device 100, which includes a liquid storage box assembly 11, an outer tube 12, and an atomizing assembly 13. Specifically, the liquid storage box assembly 11 is provided with an injection hole 1111; the outer tube 12 is disposed inside the liquid storage box assembly 11, and the atomizing assembly 13 is disposed inside the outer tube 12. The atomizing assembly 13 is used to heat the liquid matrix to generate aerosol; the outer tube 12 and the liquid storage box assembly 11 together define a first liquid storage chamber 15, which is used to store the liquid matrix; the outer tube 12 and the atomizing assembly 13 define a second liquid storage chamber 16, which is connected to the injection hole 1111; and a liquid guide hole 121 is provided at one end of the outer tube 12 near the injection hole 1111, which is connected to the first liquid storage chamber 15 and the second liquid storage chamber 16. Since the liquid guiding hole 121 is located at one end close to the liquid injection hole 1111, when liquid is injected into the first liquid storage chamber 15 through the liquid injection hole 1111, the air bubbles and pressure difference in the first liquid storage chamber 15 are reduced.

[0044] In some embodiments, please refer to Figure 1 and Figure 2 The aerosol generating device 100 includes a liquid storage component 14 disposed in a second liquid storage chamber 16 and in fluid communication with a liquid guide hole 121. The liquid storage component 14 is used to receive and retain a liquid matrix from a first liquid storage chamber 15. An atomizing component 13 is used to atomize the liquid matrix retained in the liquid storage component 14, thereby generating an aerosol. Because the liquid matrix is ​​held by the liquid storage component 14, the liquid matrix is ​​less likely to leak through the atomizing component 132 during transportation or storage, and the user can obtain a better taste during the initial inhalation when using the aerosol generating device 100.

[0045] In some embodiments, the liquid reservoir 14 can be made of an elastic organic porous material. The liquid reservoir 14 can have a hardness or flexibility between that of conventional flexible plant cotton / nonwoven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A), thus the structure is stable and has very low expansion after absorbing and wetting the liquid matrix, while also having a certain degree of hardness to be easily fixed and maintained. As an example, the liquid reservoir 14 can be rigid synthetic cotton.

[0046] In some embodiments, please refer to Figure 4 and Figure 5The atomizing assembly 13 includes a support tube 131, a liquid guide 132, and a heating element.

The liquid guide surface 1321 is opposite to the liquid storage unit 14 and is fluidly connected to the second liquid storage chamber 16 through the liquid guide port 1311. The liquid guide 1322 guides the liquid matrix from the liquid guide surface 1321 to the heating surface 1322. The heating element is disposed on the heating surface 1322 and is used to heat the liquid matrix located on the heating surface 1322 to generate an aerosol.

[0047] In some embodiments, the liquid guiding element 132 is located within the support tube 131 and extends axially along the support tube 131.
