The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.
[0029] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0030] In order to enable those skilled in the technical field to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0031] The embodiments of this application provide an aerosol generating device, such as Figures 1 to 8As shown in the figure, it includes: a housing 10, a bracket 20, and an atomization core 30; the housing 10 is provided with an airway tube 11 communicating with the outside, and a liquid storage chamber 12 arranged around the airway tube 11, and an air inlet 13 is provided at one end of the housing 10 away from the airway tube 11; the bracket 20 is connected to the airway tube 11 and seals the liquid storage chamber 12, the bracket 20 is provided with a liquid inlet hole 21 communicating with the liquid storage chamber 12, and the bracket 20 is also provided with an air passage 22 communicating with the air inlet 13; the atomization core 30 includes a porous ceramic 31 and a heating sheet 32 arranged on the porous ceramic 31, the porous ceramic 31 is arranged on the bracket 20 and abuts against the liquid inlet hole 21, and the heating sheet 32 is arranged opposite to the airway tube 11 and adjacent to the air passage 22.
[0032] The working principle of the aerosol generating device provided by the embodiment of the present application is as follows: the liquid storage chamber 12 is used to store the liquid medicine or aerosol medium; when the user starts to suck, see Figure 3 , external gas enters the air passage 22 through the air inlet 13, and the liquid medicine or aerosol medium in the liquid storage chamber 12 enters the porous ceramic 31 through the liquid inlet hole 21 and contacts the heating sheet 32. After the heating sheet 32 is energized, it generates heat to generate aerosol from the liquid medicine or aerosol medium; the aerosol and the external gas are discharged outwards through the airway tube 11 together.
[0033] The beneficial effect of the aerosol generating device provided by the embodiment of the present application is that the heating sheet 32 of the atomization core 30 is arranged opposite to the airway tube 11, so that the aerosol generated from the liquid medicine or aerosol medium directly enters the airway tube 11, allowing the aerosol to reach the oral cavity directly. During this process, the flow path of the aerosol has no turns, reducing the loss of the aerosol and correspondingly improving the reduction degree of the aroma, thus improving the user's taste experience.
[0034] In addition, the present application uses the porous ceramic 31 as the atomization core 30. The porous ceramic 31 can conduct oil and also exchange air to control the pressure difference between the liquid storage chamber 12 and the outside (the internal pressure of the liquid storage chamber 12 is: the self-weight of the liquid medicine or aerosol medium + air, and the external pressure is: air), so that the internal pressure of the liquid storage chamber 12 is always greater than the external pressure. In this way, the liquid medicine or aerosol medium can continuously flow towards the porous ceramic 31, making the atomization core 30 fully conduct liquid, reducing the situation of oil absorption not being smooth due to steam locking, and further reducing the risk of core burning.
[0035] Furthermore, the shape of the porous ceramic 31 can be a cube, a cylinder, a cone, a trapezoid, or an irregular shape, etc. The present application does not limit this here.
[0036] Such as Figures 8 to 10As shown, further, the aerosol generating device further includes: a power supply device disposed in the housing 10; both ends of the porous ceramic 31 are respectively provided with a communication connection between the atomization chamber 311 and the accommodation hole 312.

The power supply device is electrically connected to the conductive portion 321 through the accommodation hole 312.
[0037] In this embodiment, after the liquid medicine or aerosol medium in the liquid storage chamber 12 enters the porous ceramic 31 through the liquid inlet hole 21 and contacts the heating portion 322, the conductive portion 321 is electrically connected to the power supply device to achieve conduction, so that the heating portion 322 generates heat, and the liquid medicine or aerosol medium is generated into aerosol in the atomization chamber 311. The aerosol in the atomization chamber 311 is discharged outward together with the external gas through the airway tube 11.
[0038] In this embodiment, through the settings of the atomization chamber 311 and the accommodation hole 312, the heating sheet 32 is embedded in the porous ceramic 31, which improves the bonding strength between the heating sheet 32 and the porous ceramic 31, makes the heating sheet 32 not easy to fall off, and can also separate the conductive portion 321 and the heating portion 322 to prevent the heating portion 322 from affecting the connection between the conductive portion 321 and the power supply device; in addition, in this application, the connection with the power supply device can be achieved without welding leads on the heating sheet 32, reducing the situations of unreliable welding, secondary pollution, and high defective rate that may occur during welding of leads.
[0039] Further, the heating sheet 32 can be arranged perpendicular to, parallel to, or inclined to the axial direction of the air passage 22, and this application does not limit this here.
