[0038] Embodiment:

[0039] Please refer to Figure 1 and Figure 2 The electronic atomization device provided in the embodiments of the present application comprises a base 10, an atomization assembly 20, a liquid storage cup 30, an electrode piece 40 and an elastic piece 50, the atomization assembly 20 is arranged on the base 10; the liquid storage cup 30 is arranged on the base 10, and the base 10, the liquid storage cup 30 and the atomization assembly 20 jointly enclose a liquid storage cavity 301; the electrode piece 40 is arranged on the base 10; the elastic piece 50 is connected to the electrode piece 40 and the atomization assembly 20 respectively. Among them, the liquid storage cavity 301 is used for storing atomization medium, the atomization assembly 20 is used for heating the atomization medium to generate aerosol, and the electronic atomization device further comprises a battery 60, and the battery 60 supplies power to the atomization assembly 20 through the electrode piece 40 and the elastic piece 50.

[0040] Please refer to Figures 2 to 5The atomization assembly 20 comprises a flexible sealing member 1, a rigid support member 2 and a heating body 3. The flexible sealing member 1 is provided with a mounting groove 11 and a lower liquid outlet 12 in communication with the mounting groove 11, and the lower liquid outlet 12 is in communication with a liquid storage cavity 301. The rigid support member 2 is arranged in the mounting groove 11 and is provided with one or more liquid passing holes 21, and the liquid passing holes 21 are arranged at least partially opposite to the lower liquid outlet 12. The heating body 3 comprises a hard base and a heating coating arranged on one side of the hard base. The hard base has a microporous structure, and the hard base is arranged on the side of the rigid support member 2 away from the lower liquid outlet 12 and is accommodated in the mounting groove 11. The heating coating is arranged on the side of the hard base away from the rigid support member 2 and is arranged in correspondence with the microporous structure. The rigid support member 2 and the heating body 3 are both flat, and the rigid support member 2 is in sealing contact with the flexible sealing member 1.

[0041] The rigid support member 2 is arranged in the mounting groove 11 of the flexible sealing member 1, and the rigid support member 2 is located between the heating body 3 and the flexible sealing member 1, so that the rigid support member 2 can support the flexible sealing member 1. Moreover, the heating body 3 is arranged in the mounting groove 11 of the flexible sealing member 1, and the rigid support member 2 is in sealing contact with the flexible sealing member 1, so that reliable sealing can be achieved by wrapping the heating body 3 with the flexible sealing member 1.

[0042] It should be noted that the elastic member 50 is connected to the electrode member 40 and the heating coating, respectively, that is, the heating body 3 is supported by the electrode member 40 through the elastic member 50, so that the risk of stress top crushing the heating body 3 can be avoided. Moreover, the heating body 3 is in close contact with the rigid support member 2, so that the stress of the electrode member 40 pressing against the heating body 3 can be transmitted to the rigid support member 2, and the rigid support member 2 has high structural strength, so that the flexible sealing member 1 can be supported. The rigid support member 2 is in sealing contact with the flexible sealing member 1, and the flexible sealing member 1 is also in sealing contact with the liquid storage cup 30, so that reliable sealing can be achieved by wrapping the heating body 3 with the flexible sealing member 1.

[0043] The rigid support member 2 can be made of a hard metal material, for example, the rigid support member 2 can be a stainless steel block, which can not only ensure that the rigid support member 2 has sufficient structural strength, but also can make the rigid support member 2 have good heat conduction performance, thereby improving the heat conduction effect.

[0044] It should be understood that the rigid support member 2 can absorb the heat of the heating body 3, thereby preheating the atomization medium at the lower liquid outlet 12 and avoiding the phenomenon of air bubbles.

[0045] The atomization medium in the liquid storage cavity 301 can flow into the heating body 3 through the lower liquid outlet 12 and the liquid passing holes 21, so that the amount of liquid can be adjusted by changing the number and aperture size of the liquid passing holes 21. For example, please refer to Figure 3 and Figure 4The rigid support 2 is provided with three liquid passing holes 21, which are distributed along the length direction of the rigid support 2. When two of the three liquid passing holes 21 are arranged opposite to the lower liquid outlet 12, the amount of the atomized medium flowing downward is moderate; when one of the three liquid passing holes 21 is arranged opposite to the lower liquid outlet 12, the amount of the atomized medium flowing downward is less; and when all of the three liquid passing holes 21 are arranged opposite to the lower liquid outlet 12, the amount of the atomized medium flowing downward is more.

[0046] It should be understood that the number of the liquid passing holes 21 is set according to actual needs, such as one, two, three, etc. When the rigid support 2 is provided with one liquid passing hole 21, the size of the overlapping area of the liquid passing hole 21 and the lower liquid outlet 12 can be changed to adjust the amount of the atomized medium flowing downward.

[0047] The hard base has a micro-porous structure, so that the hard base has a liquid absorption capacity. The heating coating can heat the atomized medium held by the hard base. The heating coating is in elastic contact with and electrically connected to the external electrode member 40, specifically, the heating coating is in elastic contact with the electrode member 40 through the elastic member 50. According to actual needs, the hard base can be a ceramic base or a glass base. Specifically, the hard base can be a porous glass base, a porous ceramic base, or a liquid-conducting base formed by perforating a dense glass or a dense ceramic. The hard base is in elastic contact with the electrode member 40 through the elastic member 50, which can reduce the risk of the hard base being crushed by the electrode member 40.

[0048] The porosity of the hard base ranges from 40% to 70%, such as 40%, 45%, 50%, 60%, 65%, 70%, etc., so that the hard base has a certain structural strength and a better liquid absorption capacity. The thickness of the hard base ranges from 0.5 mm to 2 mm, such as 0.5 mm, 0.8 mm, 1.2 mm, 1.6 mm, 1.8 mm, 2 mm, etc., which meets the ultra-thin characteristics of the heating body 3.

[0049] It should be noted that the hard base can only meet the above-mentioned porosity range; or the hard base can only meet the above-mentioned thickness range; or the hard base meets both the above-mentioned porosity range and the above-mentioned thickness range.

[0050] Please refer to Figure 3 and Figure 4The atomization assembly 20 further comprises a flexible liquid guide 4, which is arranged between the rigid support 2 and the hard base and accommodated in the mounting groove 11, in liquid communication with the lower liquid port 12, and capable of absorbing the atomization medium flowing to the liquid passage 21 from the lower liquid port 12. The flexible liquid guide 4 can not only absorb the atomization medium to lock the liquid, but also buffer the force between the heat generating body 3 and the rigid support 2 to avoid rigid contact. Moreover, the flexible liquid guide 4 of the same thickness has better liquid locking capacity than the ceramic base or the glass base, thereby preventing the atomization medium from leaking rapidly and ensuring that the liquid flow speed is neither too fast nor too slow.

[0051] The thickness of the flexible liquid guide 4 is in the range of 0.1 mm to 0.3 mm, for example, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.28 mm, 0.3 mm, etc. The flexible liquid guide 4 can also reduce the heat insulation effect. For example, the flexible liquid guide 4 is liquid guide cotton, which has poor heat conduction effect and is not conducive to heat conduction. That is, the heat of the heat generating body 3 can be better conducted to the atomization medium at the lower liquid port 12 through the rigid support 2, thereby achieving a preheating effect.

[0052] It should be noted that, since the flexible liquid guide 4 is arranged between the rigid support 2 and the heat generating body 3, that is, the rigid support 2 is arranged above the flexible liquid guide 4, the flexible liquid guide 4 can be prevented from swelling and deforming after absorbing the atomization liquid, thereby increasing the overall structural strength of the atomization assembly 20.

[0053] Please refer to Figure 3 , Figure 4 and Figure 6 The flexible sealing member 1 is provided with a limiting structure 13, and the side of the heat generating body 3 away from the flexible liquid guide 4 abuts against the limiting structure 13. The limiting structure 13 can limit the heat generating body 3, the flexible liquid guide 4 and the rigid support 2 in the mounting groove 11, thereby preventing the heat generating body 3, the flexible liquid guide 4 and the rigid support 2 from being separated from the mounting groove 11. According to actual needs, the limiting structure 13 can be a buckle structure, that is, the heat generating body 3 is buckled into the mounting groove 11 through the buckle structure.

[0054] Please refer to Figure 3 , Figure 4 and Figure 5 The atomization assembly 20 further comprises a reinforcing frame 5, which is arranged on the side of the flexible sealing member 1 away from the heat generating body 3, at least partially abuts against the inner circumferential wall of the lower liquid port 12, and defines a lower liquid cavity 53. The reinforcing frame 5 can not only support the flexible sealing member 1, but also prevent the flexible sealing member 1 from being extruded and deformed in the radial direction of the lower liquid port 12.

[0055] Please refer to Figure 3 and Figure 5The reinforcing frame 5 comprises an end wall part 51 and a side wall part 52, the end wall part 51 is arranged on the side surface of the flexible sealing member 1 away from the heat-generating body 3, the end wall part 51 is provided with a through hole, and the end wall part 51 is attached on the side surface of the flexible sealing member 1 away from the heat-generating body 3. The side wall part 52 is arranged on the end wall part 51 and extends towards the rigid support 2, the side wall part 52 abuts against the inner circumferential wall of the lower liquid outlet 12 and is arranged around the through hole, so as to prevent the flexible sealing member 1 from being extruded and deformed in the radial direction of the lower liquid outlet 12, and the side wall part 52 and the end wall part 51 jointly enclose a lower liquid cavity 53, and the through hole is part of the lower liquid cavity 53.

[0056] The first positioning structure is arranged on the reinforcing frame 5, the second positioning structure is arranged on the flexible sealing member 1 and matches the first positioning structure, and the first positioning structure and the second positioning structure match each other, so as to facilitate positioning when the reinforcing frame 5 and the flexible sealing member 1 are assembled.

[0057] Please refer to Figure 3 and Figure 5 In some embodiments, one of the first positioning structure and the second positioning structure is the positioning protrusion 14, and the other is the positioning groove 511, the positioning protrusion 14 is embedded into the positioning groove 511, for example, the first positioning structure is the positioning protrusion 14, and the second positioning structure is the positioning groove 511. Wherein, the positioning protrusion 14 and the positioning groove 511 are in interference fit, so as to ensure the connection firmness between the reinforcing frame 5 and the flexible sealing member 1.

[0058] Please refer to Figure 3 and Figure 6 The inner wall of the mounting groove 11 is provided with the first rib 15, the first rib 15 is in sealing contact with the side of the rigid support 2 away from the flexible liquid guide 4, the outer side of the flexible sealing member 1 is further provided with the second rib 16, the second rib 16 is used for sealing contact with the liquid storage cup 30, and the sealing of the flexible sealing member 1 to the heat-generating body 3 is realized.
