[0002] As an alternative to traditional cigarettes, an electronic atomization device generally includes a hollow housing, an atomization core disposed inside the housing, and a power supply device for supplying power to the atomization core. Among them, an air inlet channel, an air outlet channel, and a liquid storage cavity for supplying atomization liquid to the atomization core are further disposed inside the housing. The atomization core is used to heat and atomize the atomization liquid supplied by the liquid storage cavity to form an inhalable aerosol leading to the air outlet channel.

[0003] In the related art, an electrode seat for assembling electrode posts and a support frame for assembling the electrode seat and the atomization core are disposed inside the housing of the electronic atomization device. One end of the electrode post assembled on the electrode seat abuts against the atomization core, and the other end of the electrode post is connected to the power supply device. The electrode post is used to form a path between the atomization core and the power supply device and can support and fix the atomization core. Among them, in order to reduce the assembly resistance of the electrode seat to facilitate the assembly of the electrode seat, there is usually a fitting gap between the electrode seat and the support frame. Therefore, there is a situation where the actual position of the electrode seat deflects relative to the preset assembly position, which may lead to the following problems: 1. Problems such as poor contact between the atomization core and the electrode post or the atomization core being damaged by the electrode post; 2. The fitting gap between the electrode seat and the support frame is uneven, so that condensate is likely to leak at the larger gap; 3. The atomization core is stressed unevenly, resulting in the failure of the sealing structure at the atomization core, and thus the problem of atomization liquid leakage occurs.

[0034] Refer to Figures 1 to 6, The atomization component according to an embodiment of the present application includes a support frame 100, an atomization core 200, and an electrode base 300.

[0035] Specifically, the support frame 100 has an installation cavity 110. The installation cavity 110 has an open end. The atomization core 200 is disposed in the installation cavity 110. The electrode base 300 is at least partially inserted into the installation cavity 110 along a first direction from the open end of the installation cavity 110. An electrode post 310 penetrates through the electrode base 300. One end of the electrode post 310 abuts against the atomization core 200, and the other end of the electrode post 310 is used to be connected to a power supply device. Wherein, the part of the electrode base 300 inserted into the installation cavity 110 has a first insertion section 320 and a second insertion section 330 distributed along the first direction. The second insertion section 330 is closer to the open end of the installation cavity 110 than the first insertion section 320. There is a first gap between the outer peripheral side wall of the first insertion section 320 and the inner peripheral side wall of the installation cavity 110. There is a second gap greater than the first gap between the outer peripheral side wall of the second insertion section 330 and the inner peripheral side wall of the installation cavity 110. At least one of the outer peripheral side wall of the second insertion section 330 and the inner peripheral side wall of the installation cavity 110 is provided with a protruding first positioning portion 331.

[0036] Wherein, the atomization core 200 is provided with an electrode portion 210 for accessing a power supply. The end of the electrode post 310 abuts against the electrode portion 210 of the atomization core 200.

[0037] It should be noted that the first direction is the X direction in the drawings.

[0038] When assembling the electrode base 300, since the second gap is greater than the first gap, that is, the cross-sectional dimension of the part of the installation cavity 110 for accommodating the second insertion section 330 is greater than the cross-sectional dimension of the part of the installation cavity 110 for accommodating the first insertion section 320, the first insertion section 320 is easy to pass through the part of the installation cavity 110 for accommodating the second insertion section 330, which is beneficial to reducing the assembly resistance when the electrode base 300 is inserted into the installation cavity 110, so as to facilitate the assembly of the electrode base 300. Wherein, at least one of the outer peripheral side wall of the second insertion section 330 and the inner peripheral side wall of the installation cavity 110 is provided with a protruding first positioning portion 331. The first positioning portion 331 can reduce the fitting gap between the second insertion section 330 and the support frame 100, thereby restricting the deflection of the electrode base 300 relative to the preset assembly position, and further being beneficial to reducing the situation that the actual position of the electrode base 300 deflects relative to the preset assembly position.

[0039] It should be noted that, in some of the embodiments, the first positioning portion 331 is integrally formed on the second insertion section 330.

[0040] It should be noted that in some other embodiments, the first positioning portion 331 and the second insertion section 330 are of a split structure, and the first positioning portion 331 is connected to the second insertion section 330 by fasteners, which is not limited herein.

[0041] It should be noted that in some of the embodiments, the first gap is 0.05 mm - 0.12 mm. Specifically, the first gap can be 0.05 mm, can be 0.12 mm, can also be 0.1 mm, or can be other dimensions within the above dimension range, which is not limited herein.

[0042] It should be noted that in some of the embodiments, the second gap is 0.15 mm - 0.25 mm. Specifically, the second gap can be 0.15 mm, can be 0.25 mm, can also be 0.2 mm, or can be other dimensions within the above dimension range, which is not limited herein.

[0043] It should be noted that in some of the embodiments, there is a third gap between the surface of the first positioning portion 331 and the wall surface (i.e., the inner peripheral side wall of the mounting cavity 110 where the first positioning portion 331 is not provided among the outer peripheral side wall of the second insertion section 330 and the inner peripheral side wall of the mounting cavity 110) that the first positioning portion 331 faces. The third gap is smaller than the first gap, which is beneficial to ensuring the positioning effect of the first positioning portion 331.

[0044] It should be noted that in some of the embodiments, the third gap is 0 - 0.1 mm. Specifically, the third gap can be 0 mm, can be 0.1 mm, can also be 0.05 mm, or can be other dimensions within the above dimension range, which is not limited herein.

[0045] Referring to Figure 3 、 Figure 4 and Figure 6 , in some of the embodiments, the first positioning portion 331 is provided on the outer peripheral side wall of the second insertion section 330 and extends in the first direction, which can increase the length of the first positioning portion 331 in the first direction, that is, can increase the length of the first positioning portion 331 in the insertion direction of the electrode base 300, thereby being beneficial to improving the positioning effect of the first positioning portion 331. At this time, the third gap is formed between the surface of the first positioning portion 331 and the inner peripheral side wall of the mounting cavity 110 that the first positioning portion 331 faces.

[0046] Referring to Figure 4 , in some of the embodiments, when the first positioning portion 331 is provided on the outer peripheral side wall of the second insertion section 330, a guiding inclined surface 3311 is provided at one end of the first positioning portion 331 away from the opening end of the mounting cavity 110, so as to facilitate the insertion of the electrode base 300 into the mounting cavity 110.

[0047] Referring to Figure 3and Figure 4 In some embodiments, the number of the first positioning portions 331 is plural, and the plural first positioning portions 331 are distributed at intervals along the circumferential direction of the second insertion section 330, which is beneficial to avoiding the problem of uneven second gaps, and is not only beneficial to improving the positioning effect of the first positioning portions 331, but also beneficial to preventing the leakage of condensate from the second gaps.

[0048] It should be noted that, in some embodiments, the plural first positioning portions 331 are symmetrically arranged on the outer peripheral side wall of the second insertion section 330 to reduce the possibility that the actual position of the electrode seat 300 deflects relative to the preset assembly position.

[0049] It should be noted that, in some other embodiments, the first positioning portions 331 may also be arranged on the inner peripheral side wall of the installation cavity 110, which is not limited herein. At this time, a third gap is formed between the surface of the first positioning portion 331 and the outer peripheral side wall of the second insertion section 330 facing the first positioning portion 331. At the same time, the guiding inclined surface 3311 of the first positioning portion 331 is arranged at one end of the first positioning portion 331 close to the open end of the installation cavity 110.

[0050] It should be noted that, in some other embodiments, the first positioning portions 331 are arranged on both the outer peripheral side wall of the second insertion section 330 and the inner peripheral side wall of the installation cavity 110, which is not limited herein. At this time, the first positioning portions 331 on the outer peripheral side wall of the second insertion section 330 and the first positioning portions 331 on the inner peripheral side wall of the installation cavity 110 are arranged in alignment with each other or offset from each other.

[0051] Referring to Figure 3 、 Figure 4 and Figure 6 In some embodiments, a limiting portion 340 extending outward is provided at one end of the electrode seat 300 facing away from the atomization core 200, and the limiting portion 340 abuts against the end surface of the open end of the installation cavity 110. On the one hand, the limiting portion 340 can limit the depth of insertion of the electrode seat 300 into the installation cavity 110; on the other hand, when the electrode seat 300 has a tendency to deflect relative to the preset assembly position, the limiting portion 340 abutting against the end surface of the open end of the installation cavity 110 can limit the electrode seat 300, thereby being beneficial to further reducing the situation that the actual position of the electrode seat 300 deflects relative to the preset assembly position.

[0052] Referring to Figure 6, in some of these embodiments, a raised second positioning portion 120 is provided on the inner top wall of the installation cavity 110 corresponding to the end face of the electrode base 300 facing the atomization core 200. The second positioning portion 120 can reduce the fitting gap between the end face of the electrode base 300 facing the atomization core 200 and the inner top wall of the installation cavity 110, thereby facilitating further reduction of the deflection of the actual position of the electrode base 300 relative to the preset assembly position.

[0053] It should be noted that, in some of these embodiments, there is a fourth gap between the second positioning portion 120 and the end face of the electrode base 300 facing the atomization core 200. The fourth gap is 0 - 0.1 mm. Specifically, the fourth gap can be 0 mm, can be 0.1 mm, can also be 0.05 mm, or can be other dimensions within the above size range, which is not limited herein.

[0054] Refer to Figure 1 and Figure 3 , in some of these embodiments, a first sealing ring 400 is sleeved outside the first insertion section 320 and abuts against the inner peripheral side wall of the installation cavity 110, thereby facilitating prevention of leakage of condensate through the first gap.

[0055] Refer to Figure 4 , in some of these embodiments, a positioning groove 321 for embedding the first sealing ring 400 is provided on the outer peripheral side wall of the first insertion section 320 or on the inner peripheral side wall of the installation cavity 110. The positioning groove 321 can fix the first sealing ring 400, which is beneficial to the assembly difficulty on the one hand and beneficial to improving the stability and reliability of the first sealing ring 400 during operation on the other hand.

[0056] Refer to Figure 1 and Figure 6 , in some of these embodiments, an air inlet channel 350 communicating with the installation cavity 110 is provided on the electrode base 300, and an air outlet channel 130 communicating with the installation cavity 110 is provided on the support frame 100.

A liquid collecting groove 360 corresponding to the air inlet end of the air outlet channel 130 is provided on the support frame 100. The liquid collecting groove 360 is used for collecting the condensate adhering to the inner wall of the air outlet channel 130, which is beneficial to preventing the condensate from leaking through the first gap and the second gap.

An opening communicating the installation cavity 110 and the air outlet channel 130 is formed at one end of the extension part facing the air outlet channel 130, and at least part of the opening is directly opposite to the air inlet end of the air outlet channel 130. By adding an extension part to the support frame 100, the liquid collecting groove 360 is at least partially formed in the extension part to increase the volume of the liquid collecting groove 360.

[0059] Referring Figure 1 and Figure 6 , in some of the embodiments, the air inlet end of the air inlet channel 350 is flared, which is beneficial to reducing the air inlet resistance when the user sucks, so as to increase the flow rate of external air entering the inside of the electronic atomization device.
