[0031] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0032] like Figures 1 to 3 As shown, an aerosol generator 10 according to one embodiment includes a liquid storage component 100, a liquid stabilizing component 200, and a thermal radiation heater 300. The liquid storage component 100 forms a liquid storage chamber 102 and an air inlet atomizing channel 104. The inner peripheral wall of the air inlet atomizing channel 104 is provided with an installation groove 104a, which communicates with the liquid storage chamber 102. The liquid stabilizing component 200 is located within the installation groove 104a and connected to the liquid storage component 100. In this embodiment, the liquid stabilizing component 200 not only stabilizes the liquid but also guides it, ensuring a more uniform flow of atomized liquid from the liquid storage chamber 102 into the installation groove 104a, thus avoiding problems of excessive or insufficient atomized liquid volume in the installation groove 104a. It can be understood that the liquid storage chamber 102 is used to store the atomized liquid, which can be a medicinal liquid, e-liquid, or other atomizing medium.

[0033] In one of the embodiments, the liquid stabilizing assembly 200 is formed with an atomization generating cavity 202 in communication with the air inlet atomization flow channel 104. The thermal radiation heating body 300 is at least partially located in the atomization generating cavity 202, and an airflow gap 204 is formed between the thermal radiation heating body 300 and the atomization generating cavity 202 to avoid direct contact between the thermal radiation heating body 300 and the inner circumferential wall of the atomization generating cavity 202. The thermal radiation heating body 300 is provided with an electrically conductive heating portion 302, and an outer wall of the electrically conductive heating portion 302 is provided with a thermal radiation surface 302a that generates heat when the electrically conductive heating portion 302 conducts electricity.

[0034] The aerosol generating device 10 described above has the liquid stabilizing assembly 200 located in the mounting groove 104a and connected with the liquid storage assembly 100. The liquid stabilizing assembly 200 is formed with the atomization generating cavity 202 in communication with the air inlet atomization flow channel 104, so that the atomized liquid in the liquid storage cavity 102 flows into the mounting groove 104a to contact the liquid stabilizing assembly 200. The liquid stabilizing assembly 200 plays a role in guiding and stabilizing the liquid. In addition, the thermal radiation heating body 300 is at least partially located in the atomization generating cavity 202, and the thermal radiation heating body 300 is provided with the electrically conductive heating portion 302. An outer wall of the electrically conductive heating portion 302 is provided with the thermal radiation surface 302a. Moreover, the airflow gap 204 is formed between the thermal radiation heating body 300 and the atomization generating cavity 202.

The heat generated by the electrically conductive heating portion 302 when conducting electricity acts on the inner circumferential wall of the atomization generating cavity 202 in the form of thermal radiation. At the same time, the thermal radiation surface 302a is not in direct contact with the inner circumferential wall of the atomization generating cavity 202, which avoids the problems of a burnt wick or insufficient oil supply, or the problems of oil explosion or a hissing sound when smoking due to excessive oil supply, thereby improving the user experience of the aerosol generating device 10.

[0035] As shown in FIG. 4, Figure 3 In one of the embodiments, the electrically conductive heating portion 302 is at least partially located in the atomization generating cavity 202, so that the heat generated by the electrically conductive heating portion 302 can better act on the inner circumferential wall of the atomization generating cavity 202, and the heat generated by the electrically conductive heating portion 302 can better act on the liquid stabilizing assembly 200.

[0036] As shown in FIG. 4, Figure 3As shown in the drawings, in one embodiment, the conductive heating part 302 is arranged in the atomization generating cavity 202, so that the heat generated by the conductive heating part 302 can better act on the inner wall of the atomization generating cavity 202, and then the heat generated by the conductive heating part 302 can better act on the liquid stabilizing assembly 200, so that the aerosol gas is better generated. It can be understood that in other embodiments, the conductive heating part 302 is not limited to being arranged in the atomization generating cavity 202. For example, the conductive heating part 302 is partially arranged in the atomization generating cavity 202.

[0037] As shown in the drawings, Figure 3 In one embodiment, the conductive heating part 302 is coaxially arranged with the liquid stabilizing assembly 200, so that the heat generated by the conductive heating part 302 can uniformly act on the inner wall of the atomization generating cavity 202.

[0038] As shown in the drawings, Figure 3 In one embodiment, the conductive heating part 302 is arranged opposite to the liquid stabilizing assembly 200, that is, the heat radiation surface 302a of the conductive heating part 302 is arranged opposite to the inner wall of the liquid stabilizing assembly 200, so that the heat generated by the heat radiation surface 302a can better act on the inner wall of the liquid stabilizing assembly 200. In this embodiment, the conductive heating part 302 is coaxially arranged with the liquid stabilizing assembly 200, and the conductive heating part 302 is arranged opposite to the liquid stabilizing assembly 200, and the shortest distance from each position of the heat radiation surface 302a to the inner wall of the liquid stabilizing assembly 200 is equal.

The heat radiation surface 302a is arranged towards the heat absorbing sleeve 220, so that the heat of the heat radiation surface 302a can effectively act on the heat absorbing sleeve 220, and then the heat absorbing sleeve 220 quickly absorbs heat and acts on the liquid guide 210. Further, the atomization generating cavity 202 is formed in the heat absorbing sleeve 220, and the heat absorbing sleeve 220 is further formed with an atomization hole 222 communicating with the atomization generating cavity 202, so that the aerosol gas generated by the atomization of the atomization liquid of the liquid guide 210 can effectively flow out through the atomization hole 222, and the atomization effect of the aerosol generating device 10 is improved.

[0040] As shown in the drawings, Figure 3As shown, further, the liquid guide 210 is sleeved with the heat absorbing sleeve 220, so that the heat absorbed by the heat absorbing sleeve 220 acts on the inner circumferential wall of the heat conducting member quickly, improving the atomization effect of the aerosol generating device 10.

In addition, the heat of the sleeve portion 223 can be conducted to the first extension fixing portion 225 and the second extension fixing portion 227 respectively, so that the area of contact between the heat absorbing sleeve 220 and the liquid guide 210 is larger, and the heat absorbing sleeve 220 can better heat and atomize the liquid guide 210. In addition, the first extension fixing portion 225 and the second extension fixing portion 227 respectively wrap the two end surfaces of the liquid guide 210, so that the liquid guide 210 has a certain tightness, and the problem of liquid leakage of the liquid guide 210 is better avoided.
