[0033] During assembly, the atomizer core 2 and the bracket 4 are first assembled, and the electrode 3 and the base 1 are assembled. During the process of assembling the shell 5, the bracket 4 and the base 1, the lead 23 is connected to the electrode 3, achieving stable circuit conduction and facilitating the connection of the lead 23 and the electrode 3. The connection between the electrode 3 and the lead 23 is easy, which reduces the assembly difficulty and assembly cost, thereby reducing product cost and improving competitive advantage. By adopting the above-mentioned atomizer, the cost of the electronic atomization device is reduced. The power supply component is electrically connected to the electrode 3 exposed on the outer surface of the base 1, and the electrode 3 conducts the heating element 22 through the lead 23. The atomizer core 2 stores a liquid matrix such as tobacco oil, tobacco liquid, etc. The heating element 22 is connected to the power supply component such as a battery through the electrode 3 to achieve circuit conduction, thereby heating the liquid matrix, causing it to evaporate and atomize into an aerosol.

[0034] Optionally, when the base 1 is assembled to the bracket 4, another portion of the electrode 3 can squeeze the portion of the lead 23 held on the outer surface of the bracket 4, thereby maintaining contact. The squeeze between the lead 23 and the electrode 3 further ensures conduction stability.

In one embodiment, one of the bracket 4 and the base 1 is provided with a limiting groove, and the other is provided with a limiting column, and the limiting column is inserted into the limiting groove to achieve circumferential limitation of the two. In this embodiment, the bracket 4 is provided with a card slot 43, and the base 1 is provided with a boss 13, and the boss 13 is engaged in the card slot 43. Specifically, the outer side of the bracket 4 is provided with a limiting groove, and the base 1 is provided with a limiting column.

When the bracket 4 is installed in the mounting groove 11 of the base 1, the limiting column is inserted into the limiting groove. Optionally, the bracket 4 is roughly cylindrical, and two limiting grooves are provided on its outer circumference. Correspondingly, the base 1 is provided with two limiting columns.

[0037] Bracket 4 is provided with a second stopper, which abuts base 1 to restrict base 1 from moving toward the top of housing 5, thereby limiting the axial position of bracket 4 and base 1. Housing 5 is provided with a first stopper 53, which abuts bracket 4 to restrict bracket 4 from moving toward the top of housing 5, thereby limiting the axial position of bracket 4 and housing 5. During assembly, bracket 4 is assembled with base 1, and then with housing 5. Bracket 4 ensures axial position between housing 5 and base 1.

[0038] A wire groove 42 is provided on the outer surface of the bracket 4, and a portion of the lead 23 is snapped into the wire groove 42, thereby reliably retaining the lead 23 on the outer surface of the bracket 4. Optionally, the outer surface of the bracket 4 has a bump that defines the boundary of the wire groove 42. A portion of the lead 23 is bent and suspended on the bump, further preventing the lead 23 from falling off the outer surface of the bracket 4 and ensuring the stable installation of the lead 23 and the bracket 4.

[0039] Optionally, the base 1 is provided with a mounting groove 11, and a portion of the bracket 4 is provided in the mounting groove 11, resulting in a compact structure. For example, the base 1 is provided with a first limiting platform 14, and the second limiting portion of the bracket 4 is a protrusion, further simplifying the structure. The first limiting platform 14 and the protrusion abut against each other along the direction in which the bracket 4 is installed on the housing 5, thereby achieving axial limiting of the two.

[0040] Optionally, the base 1 is provided with a through-hole 12, through which external air flows in. Optionally, the through-hole 12 is formed at the bottom of the mounting groove 11. Optionally, a protrusion 421 is provided in the mounting groove 11 of the base 1, and the through-hole 12 is formed in the protrusion 421. The atomizer further includes a liquid absorbing medium 7, such as a liquid absorbing cotton. The liquid absorbing medium 7 is provided in the mounting groove 11 and sleeved on the protrusion 421. The bottom of the first sealing member 6 abuts against the liquid absorbing medium 7. When liquid leaks between the atomizing core 2 and the through-hole 12, the liquid absorbing medium 7 can absorb the leaked liquid.

[0041] The base 1 and the electrode 3 are an integrally formed structure such as injection molding, which reduces assembly and material costs. In one embodiment, the electrode 3 includes a first connecting portion 31 and a second connecting portion 32, the first connecting portion 31 is arranged in the mounting groove 11, the second connecting portion 32 is arranged at the bottom of the mounting groove 11, and the second connecting portion 32 is exposed to the base 1, and the second connecting portion 32 is used to electrically connect to the power supply assembly, so as to facilitate the connection of the electrode 3 to the power supply assembly and the lead 23 respectively. Optionally, the first connecting portion 31 and the second connecting portion 32 are arranged at an angle, such as a 90° angle, so that the electrode 3 is L-shaped. By setting the L-shaped electrode 3, the contact area between the second connecting portion 32 and the base 1 is increased, which is convenient for injection molding, and can increase the contact area between the second connecting portion 32 and the power supply assembly to achieve stable circuit conduction. In other embodiments, the angle between the first connecting portion 31 and the second connecting portion 32 can also be 30°, 45° or 100°, etc., without limitation. In one embodiment, the electrode 3 is in a sheet shape, which further increases the contact area between the electrode 3 and the lead 23 and achieves stable circuit conduction.

[0042] Optionally, the heating element 22 is a resistance wire or other element, and the lead 23 is connected to the resistance wire. For example, the resistance wire is connected to the two leads 23. Accordingly, two slots 43 are provided on the outside of the bracket 4. The two leads 23 are correspondingly engaged in the two slots 43. The two leads 23 are correspondingly pressed against the two electrodes 3. The two electrodes 3 are respectively connected to the positive and negative poles of the power supply component, thereby achieving circuit conduction of the resistance wire.

[0043] The atomizer core 2 also includes a sleeve 27, a second liquid-conducting medium 26, and a first liquid-conducting medium 25. Both the second liquid-conducting medium 26 and the first liquid-conducting medium 25 can be made of cotton.

The heating element 22 heats the liquid matrix on the second liquid-conducting medium 26 to achieve atomization.

[0044] The bracket 4 defines a receiving cavity 41, which receives the atomizer core 2. The atomizer further includes a first seal 6 and a second seal 8 connected to the bracket 4. The first and second seals 6 and 8 are disposed at opposite ends of the atomizer core 2 to seal the receiving cavity 41 and prevent leakage of the liquid matrix. Specifically, the first and second seals 6 and 8 are both made of silicone.

[0045] Part of the lead wire 23 extends from the bottom of the bracket 4 and is bent and retained on the outer surface of the bracket 4. There is no need to provide an opening or other structure on the bracket 4 to achieve the lead wire passing through, which simplifies the structure and facilitates installation.

[0046] In one embodiment, the first sealing member 6 is provided with a groove 621 at one end facing the base 1, and the lead 23 is bent and passed through the groove 621. After the lead 23 is bent, it is installed in the wire groove 42, which facilitates assembly and achieves the limitation of the lead 23. Furthermore, the bottom of the bracket 4 is provided with an upwardly extending air-avoidance groove 44, and the lead 23 is passed through the air-avoidance groove 44, so that the lead 23 can smoothly transition from the inside to the outside and avoid the lead 23 from breaking due to excessive bending angle.
