[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The terms "upper", "lower", "inner", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they cannot be understood as limitations on this application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances. The terms "first" and "second" are only used for the convenience of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features.

[0028] See also Figures 1 to 3 The embodiment of the present application provides an aerosol generating structure 100 and a heat-not-burn device having the same. The aerosol generating structure 100 can heat the aerosol generating matrix 403 so that the aerosol generating matrix 403 is heated to generate an aerosol that can be inhaled. The aerosol generating matrix 403 can be solid or a paste of a solid-liquid mixture. In this embodiment, the aerosol generating matrix 403 is a solid sheet. In other embodiments, it can be selected according to actual conditions and is not limited here.

[0029] See also Figures 1 to 3 The aerosol generating structure 100 comprises: a heating housing 200 having a heating chamber 203, a heat source 400 located in the heating chamber 203, and a driving assembly 401 connected to the heating housing 200.

[0030] The heating chamber 203 is used to accommodate the aerosol generating substrate 403. When the heating housing is placed vertically, the aerosol generating substrate 403 is laid flat on the bottom of the heating chamber 203. The heat source 400 is arranged relative to the aerosol generating substrate 403 and is used to heat the corresponding area of ​​the aerosol generating substrate 403, and the projection of the heating surface of the heat source 400 on the aerosol generating substrate 403 along the vertical direction covers a partial area of ​​the aerosol generating substrate 403.

[0031] The driving assembly 401 is used to drive the heat source 400 to rotate relative to the aerosol generating substrate 403, and to make the heat source rotate about a fixed axis to heat different regions of the aerosol generating substrate 403. It is understandable that the driving assembly 401 drives the heat source 400 to rotate. After the rotation is in place, the heat source 400 can radiate heat toward the aerosol generating substrate 403 by means of thermal radiation, and the region of the aerosol generating substrate 403 facing the heat source 400 is heated to release aerosol, while other positions of the aerosol generating substrate 403 do not need to be heated to the temperature for releasing aerosol, so that the aerosol generating substrate 403 does not need to be heated as a whole, thereby saving energy and improving energy utilization.

[0032] Optionally, the aerosol generating structure 100 can act on the aerosol generating matrix 403 in a variety of ways, including resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, etc. In this embodiment, the heat source uses a laser light source to heat the aerosol generating matrix 403. When the laser beam irradiates the surface of the aerosol generating matrix 403, the light energy is absorbed by the aerosol generating matrix 403 and converted into heat energy, causing the surface temperature of the aerosol generating matrix 403 to increase, thereby releasing aerosol. Laser light source heating is efficient, centralized and controllable. In other embodiments, the heat source can also be other heating methods, which can be selected according to actual conditions and are not limited here.

A slide groove may be opened on the inner wall of the heating chamber 203, and the extension path of the slide groove is a straight line. The driving component 401 drives the heat source 400 to slide along the slide groove, thereby realizing the translation of the heat source 400 and locally heating the aerosol generating matrix 403.

[0037] See also Figures 1 to 3 In some embodiments, any point on the translational trajectory of the heat source 400 is at the same distance from the aerosol generating substrate 403 .

[0038] See also Figures 1 to 3 It can be understood that the plane determined by the translational trajectory of the heat source 400 is parallel to the surface of the aerosol generating substrate 403 facing the heat source 400, so that the heat source 400 has the same local heating power on the aerosol generating substrate 403 during each heating process, and the heated area of ​​the aerosol generating substrate 403 is the same each time. By changing the position of the heat source 400, uniform heating of each area of ​​the aerosol generating substrate 403 is achieved, so that the consistency of aerosol generation in the heating chamber 203 is high, and the consistency of the smoking taste is improved.

[0039] It can be understood that the heat source 400 has a rotation center, and the driving component 401 is used to drive the heat source 400 to rotate around its rotation center, so that different areas of the aerosol generating substrate 403 can be heated in sequence.

[0040] See also Figures 1 to 3 In some embodiments, any point on the rotation trajectory of the heat source 400 is at the same distance from the aerosol generating substrate 403 .

[0041] See also Figures 1 to 3 It can be understood that the plane determined by the rotation trajectory of the heat source 400 is parallel to the surface of the aerosol generating substrate 403 facing the heat source 400, so that the heat source 400 has the same local heating power on the aerosol generating substrate 403 during each heating process, and the heated area of ​​the aerosol generating substrate 403 is the same each time. By changing the position of the heat source 400, uniform heating of each area of ​​the aerosol generating substrate 403 is achieved, so that the consistency of aerosol generation in the heating chamber 203 is high, and the consistency of the smoking taste is improved.

[0043] The driving component 401 drives the heat source 400 to rotate at a single angle ranging from 15° to 90°, and the heat source 400 rotates once, twice or three times in the suction interval. When the heat source rotates on a fixed axis, the rotation angle range each time can be 15° to 85.5°, 21° to 75°, 33° to 66°, 45° to 58°, 50° to 83°, 38° to 90°. It is also possible that when the heat source rotates on a fixed axis, the rotation angle each time can be 15°, 28°, 29°, 33°, 43°, 59°, 62.3°, 72.1°, 90°.

[0047] See also Figures 1 to 3 Optionally, the driver can be a motor, which drives the rotating shaft 402 to rotate through a transmission mechanism. The transmission mechanism can be a gear transmission group. The rotating shaft 402 drives the heat source 400 to rotate during the rotation process, thereby forming a rotating heating source on the aerosol generating matrix 403, so that different areas of the aerosol generating matrix 403 are heated by the heat source 400 in turn.

[0048] In some embodiments, the cross-section of the heating chamber 203 is circular, sector-shaped, elliptical, or polygonal.

[0051] In some embodiments, the heating shell 200 is provided with an air inlet channel 301 and an air outlet channel 302. The air inlet channel 301 is used to allow air to flow into the heating chamber 203, and the air flows through the aerosol generating matrix 403 and flows out of the heating chamber 203 through the air outlet channel 302, thereby bringing the generated aerosol out of the heating chamber.

[0052] See also Figures 1 to 3 Optionally, when the aerosol generating structure 100 is arranged in the vertical direction, the air inlet channel 301 is located below the heating chamber 203, and the air outlet channel 302 is located above the heating chamber 203.
