[0030] See also Figure 1-6 The present invention provides an electronic atomization device, comprising: an atomizer 1, a battery rod assembly 2 and an airway plug 3; the battery rod assembly 2 is connected to one end of the atomizer 1; the atomizer 1 has a first airway 100, the first airway 100 is connected to the atomization core to provide airflow to generate aerosol. The battery rod assembly 2 has a second airway 20, the first airway 100 and the second airway 20 are connected, and the second airway 20 provides air intake to the first airway 100; at least one of the atomizer 1 and the battery rod assembly 2 is provided with a first bracket 4, and the first airway 100 and the second airway 20 are connected through the first bracket 4; the airway plug 3 is assembled at the connection between the first airway 100 and the second airway 20 in the first bracket 4, and the airway plug 3 has an airflow channel 10 connecting the first airway 100 and the second airway 20, and the airway plug 3 is used to prevent the leakage from flowing to the airflow channel 10 and the second airway 20.

[0031] The electronic atomization device of the present invention includes an atomizer 1 and a battery rod assembly 2, wherein the atomizer 1 has a first airway 100, the battery rod assembly 2 has a second airway 20, and the electronic atomization device further includes a first bracket 4 and an airway plug 3. The airway plug 3 is assembled at the connection between the first airway 100 and the second airway 20, and the airway plug 3 can be used to prevent the leakage from flowing to the second airway 20, thereby protecting the battery rod assembly 2. In addition, the airway plug 3 has an airflow channel 10 connecting the first airway 100 and the second airway 20, so that the airflow can flow between the first airway 100, the airflow channel 10 and the second airway 20. Compared with the electronic atomization device of the related art, the present invention has the effects of good leakage prevention effect, simple structure and low cost.

[0032] For further information, see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the airway plug 3 includes a main body 31 and a first connecting part 32, and the first bracket 4 includes a second connecting part; the first connecting part 32 is assembled on the second connecting part, and an airflow channel 10 is provided between the first connecting part 32 and the second connecting part; the main body 31 is connected to the first connecting part 32, and the main body 31 is located at one end of the second connecting part close to the first airway 100, the axial projection surface of the main body 31 covers the airflow channel 10, and a liquid guiding structure 311 is provided at one end of the main body 31 away from the first connecting part 32, and the liquid guiding structure 311 is used to guide the leaked liquid to flow in a direction away from the airflow channel 10.

[0033] Specifically, the main body 31 can be integrally connected with the first connection part 32, or can be separately provided with the first connection part 32. In the axial direction of the electronic atomization device, the main body 31 is connected with the first connection part 32, and the first connection part 32 is assembled and connected with the second connection part, and the airflow channel 10 is formed between the first connection part 32 and the second connection part, and the main body 31 is located at one end of the second connection part close to the first airway 100. Therefore, when the axial projection surface of the main body 31 covers the airflow channel 10, it is equivalent to that the main body 31 can cover the airflow channel 10. Therefore, even if the atomized liquid flows downward from the first airway 100, the atomized liquid will be blocked by the main body 31, so it is difficult to flow to the airflow channel 10. Furthermore, a liquid guiding structure 311 is provided at one end of the main body 31 close to the first air channel 100. The liquid guiding structure 311 has a guiding effect on liquid leakage. When the atomized liquid leaks downward from the first air channel 100, the liquid guiding structure 311 will guide the atomized liquid to flow in a direction away from the air flow channel 10, so that the leaked liquid will not flow to the air flow channel 10 and the second air channel 20, thereby protecting the battery rod assembly 2.

[0034] For further information, see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The main body 31 includes a truncated cone structure, an umbrella structure, an arrow-shaped structure, a conical structure or a triangular prism structure.

[0035] Specifically, in some embodiments, the main body 31 may be a truncated cone structure, and the area of ​​the upper surface is smaller than that of the lower surface, the first connecting portion 32 is connected to the lower bottom surface, and the lower bottom surface covers the airflow channel 10, and the side of the truncated cone serves as a liquid guiding structure 311 to guide the leaked liquid to flow in a direction away from the airflow channel 10. In some embodiments, the main body 31 may be an umbrella structure, and the liquid guiding structure 311 is an umbrella surface, the top of the umbrella surface faces the first airway 100, and the unfolded portion of the umbrella surface covers the airflow channel 10. Therefore, when the atomized liquid leaks downward from the first airway 100, the atomized liquid will first contact the top of the umbrella surface, and then flow along the side of the unfolded portion of the umbrella surface away from the airflow channel 10. Therefore, the atomized liquid will not flow to the airflow channel 10 and the microphone channel, thereby protecting the battery rod assembly 2. In some embodiments, the main body 31 can be an arrow-shaped structure. Similarly, the top of the arrow faces the first airway 100, the arrow head covers the airflow channel 10, and the liquid guiding structure 311 is around the arrow head. The atomized liquid will flow around the arrow head instead of flowing to the second airway 20. In some embodiments, the main body 31 can be a conical structure. Similarly, the bottom surface of the cone is connected to the first connecting portion 32, and the bottom surface of the cone covers the airflow channel 10. The liquid guiding structure 311 is the side of the cone, and the atomized liquid flows along the side of the cone. In some embodiments, the main body 31 can be a triangular prism structure, one of the side surfaces is connected to the first connecting portion 32 and covers the airflow channel 10, and the other two side surfaces serve as the liquid guiding structure 311, which can guide the leaked liquid to flow away from the airflow channel 10. In some other embodiments, the main body 31 can also be a structure of other shapes, and the liquid guiding structure 311 can be an arc structure extending circumferentially and radially, or an inclined plane structure, etc.

[0036] It should be noted that the airflow channel 10 can be arranged inside or outside the airway plug 3. When the airflow channel 10 is arranged outside the airway plug 3, the airflow channel 10 is arranged on the surface of the first connecting part and / or the second connecting part. The liquid guiding structure 311 connects the first airway 100 and is away from the airflow channel 10 and the second airway 20. The liquid guiding structure 311 diverts leakage such as atomized liquid or condensed liquid to prevent leakage from entering the battery rod assembly 2 from the second airway 20.

[0037] When the airflow channel 10 is disposed inside the airway plug 3, the main body 31 separates the first airway 100 and the second airway 20. If the top of the main body 31 is closed, the first airway 100 and the second airway cannot be directly connected. The main body 31 is provided with an opening, which is connected to the airflow channel 10 and avoids the liquid guide structure 311. Preferably, the opening is provided at the bottom of the airway plug 3, and the airflow channel 10 is opened from the bottom of the airway plug 3 toward the top, and then bends and extends to the second airway 20.

[0038] For further information, see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , the airflow channel 10 includes a first sub-airflow channel opened inside the second connection part, and a second sub-airflow channel formed between the first connection part 32 and the second connection part, and the first sub-airflow channel, the second sub-airflow channel and the third sub-airflow channel are connected. Specifically, the first airway 100 and the second airway 20 both extend along the axial direction of the electronic atomization device, and the airflow channel 10 is divided into a first sub-airflow channel and a second sub-airflow channel, wherein the first sub-airflow channel extends along the axial direction of the electronic atomization device. The airflow can circulate in the first airway 100, the second sub-airflow channel, the first sub-airflow channel and the second airway 20.

[0039] Further, in some embodiments, see Figure 1 , Figure 4 and Figure 5 The first connecting part 32 includes a first tooth structure, and the second connecting part includes a second tooth structure enclosing a first sub-airflow channel. The first tooth structure and the second tooth structure are connected, and there are a plurality of first intervals between the end of the first tooth structure away from the main body part 31 and the second tooth structure; the plurality of first intervals form a second sub-airflow channel.

[0040] Specifically, the first tooth-like structure includes a plurality of first protrusions 321 spaced apart at an end of the first main body portion 31 away from the liquid-conducting structure 311; the second tooth-like structure includes a base portion enclosing a first sub-airflow channel, and second protrusions 41 spaced apart at the base portion; the first protrusions 321 and the second protrusions 41 are alternately arranged, the peripheral side of the first protrusion 321 abuts against the peripheral side of the second protrusion 41, and a first interval is formed between the end of the first protrusion 321 away from the first main body portion 31 and the base portion.

[0041] In this embodiment, two adjacent second protrusions 41 and the base form a slot, the first protrusion 321 is correspondingly located in the slot, and there is a gap between the first protrusion 321 and the bottom of the slot. The first connecting portion 32 also includes a columnar structure connected to the main body 31, one end of the first protrusion 321 is connected to the main body 31, and one side of the first protrusion 321 is connected to the columnar structure. When the first protrusion 321 and the second protrusion 41 are alternately arranged, the side of the second protrusion 41 abuts against the first protrusion 321, and the side of the second protrusion 41 abuts against the columnar structure, and one end of the second protrusion 41 abuts against an end of the main body 31 close to the first connecting portion 32. Therefore, the first interval only includes the gap space between the first protrusion 321 and the bottom of the slot. The first gap serves as the second sub-airflow channel of this embodiment, which is used as a flow path for airflow. Through the interaction between the first protrusion 321 and the second protrusion 41, the airway plug 3 can be stably assembled on the first bracket 4.

[0042] For further information, see Figure 2 and Figure 6 In some embodiments, the first connection portion 32 includes an end portion 322 and a groove 323 formed between the end portion 322 and the main body portion 31; the second connection portion has a main body 42 that encloses a first sub-airflow channel, and at least two extension portions 43 that are spaced apart. The end of the main body 42 close to the first connection portion 32 has an end face 421, and the extension portion 43 extends from the end face 421 toward the first connection portion 32; the end of the extension portion 43 away from the end face 421 is clamped in the groove 323, and a second interval is provided between the end of the end 322 away from the groove 323 and the end face 421. The second interval and the gap between two adjacent extension portions 43 form a second sub-airflow channel.

[0043] Specifically, the first connecting portion 32 includes a column connected to the main body 31 and an end 322 connected to the column, which is equivalent to the airway plug 3 including the main body 31, the column and the end 322 in sequence. Taking the main body 31 as the top of the airway plug 3 as an example, the area of ​​the bottom side of the main body 31 can be greater than the area of ​​the top surface of the column, or, in the radial and circumferential directions, the bottom side of the main body 31 at least partially exceeds the column; the end 322 can be a columnar structure, but the area of ​​the top surface of the end 322 is greater than the area of ​​the bottom surface of the column, or, in the radial and circumferential directions, the side of the end 322 close to the column at least partially exceeds the column. Therefore, a groove 323 can be formed between the end 322 and the main body 31 for clamping the extension 43 of the first bracket 4. The second connecting portion includes a main body 42 and an extension 43, and the main body 42 is a columnar structure with a circular cross-sectional shape, wherein there is a through hole inside for forming a first sub-airflow channel. The side of the body 42 close to the first connection part 32 is the end face 421, that is, the top surface of the body 42 is the end face 421, and the extension part 43 extends upward from the end face 421. According to the size of the extension part 43 in the radial and circumferential directions, the number of extension parts 43 can be determined. When the extension part 43 is larger in the radial and circumferential directions, only two extension parts 43 can be set; when the extension part 43 is smaller in the radial and circumferential directions, the number of extension parts 43 can exceed two, and it is only necessary to ensure that multiple extension parts 43 are arranged at intervals so that there is a gap between the extension parts 43 and the extension parts 43. Each extension part 43 is provided with an assembly groove connected to the through hole of the body 42, and the opening of the assembly groove is facing the central axis of the electronic atomization device. From the central axis of the electronic atomization device to the circumferential side, the extension part 43 forms an L-shaped structure, wherein the assembly groove is used to accommodate the end 322 of the first connection part 32, and one side of the extension part 43 is connected to the first connection part 32 as a connecting side. When the extension portion 43 is connected to the first connection portion 32, the connection edge of the extension portion 43 is clamped in the groove 323 of the airway plug 3, the bottom side of the main body 31 abuts against the top side of the connection edge, the top side of the end portion 322 abuts against the bottom side of the connection edge, and the end portion 322 is entirely located in the assembly groove of the extension portion 43. The airway plug 3 and the extension portion 43 interact with each other, so that the airway plug 3 can be stably assembled on the first bracket 4. There is a second gap between the bottom side of the end portion 322 and the end face 421, and since there is also a gap between two adjacent extension portions 43, the second gap and the gap between the extension portions 43 can form a second sub-airflow channel.

[0044] For further information, see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 A circular groove 312 is formed at one end of the main body 31 close to the first connecting portion 32 .

[0045] Specifically, the main body 31 mainly extends in the circumferential and radial directions, so that the axial projection surface of the main body 31 covers the airflow channel 10, and the main body 31 can block the airflow channel 10, and the leaked liquid is difficult to flow in the direction of the airflow channel 10. In some embodiments, the main body 31 can also extend in the axial direction, so that a roundabout groove 312 can be opened at one end of the main body 31, and the roundabout groove 312 is located on the circumferential side of the first connecting portion 32. In this way, even if there is leaked liquid from the main body 31 to the direction of the first connecting portion 32, the roundabout groove 312 of the main body 31 can block the leaked liquid and prevent the leaked liquid from continuing to penetrate downward, thereby further preventing the leaked liquid from flowing in the direction of the airflow channel 10. It should be understood that the roundabout groove 312 can be suitable for the case where the main body 31 has a small extension size in the circumferential and radial directions, such as when the axial projection surface of the main body 31 just covers the airflow channel 10, or does not exceed the airflow channel 10 by much, then the roundabout groove 312 can be used to further improve the anti-leakage effect. When the main body 31 has a large circumferential and radial extension, the return groove 312 is not required, and the airway plug 3 also has a better anti-leakage effect, which can also save materials, simplify the manufacturing process, and reduce production costs.

[0046] For further information, see Figure 3 In some embodiments, the airway plug 3 includes a vent tube 33, the vent tube 33 has a first port 331 and a second port 332, both of which face the second airway 20; the first bracket 4 includes a first through hole 44 and a connecting surface surrounding the first through hole 44; the first port 331 is interference fit with the first through hole 44, and a third interval is provided between the second port 332 and the connecting surface, and an airflow channel 10 is formed in the third interval, in the vent tube 33, and in the first through hole 44.

[0047] Specifically, the vent pipe 33 may be U-shaped, V-shaped, W-shaped, spiral-shaped, etc. The two ports of the vent pipe 33 are respectively a first port 331 and a second port 332, wherein the first port 331 faces the second airway 20, and the first port 331 is used to connect to the first bracket 4. The first bracket 4 includes a first through hole 44, and the first through hole 44 extends axially. By interference fitting the first port 331 and the first through hole 44, the inner side of the first port 331 abuts against the outer side of the first through hole 44, thereby achieving a stable connection between the vent pipe 33 and the first bracket 4. The second port 332 faces the second airway 20, that is, the second port 332 faces downward. Therefore, when there is leakage flowing downward from the first airway 100, due to the influence of gravity, the leakage cannot flow from the second port 332 to the inside of the vent pipe 33, and the leakage will only flow along the outermost side of the vent pipe 33. The first bracket 4 also includes a connection surface surrounding the first through hole 44. Since the second port 332 and the connection surface have a third interval, the airflow can flow in the third interval, and the third interval, the inner side of the vent pipe 33 and the inner side of the first through hole 44 can form an airflow channel 10, so that the gas can flow from the first airway 100 to the third interval, and then flow from the third interval through the inner side of the vent pipe 33 and the inner side of the first through hole 44, and finally flow to the second airway 20, so that the gas can flow between the first airway 100 and the second airway 20. Since the leaked liquid cannot flow from the second port 332 into the vent pipe 33, the leaked liquid will not flow into the first through hole 44 and the second airway 20, so that the leaked liquid can be effectively prevented from flowing into the battery rod assembly 2.

[0048] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 5 The first bracket 4 further includes a liquid storage tank 45 which is arranged on the side of the airway plug 3 and opens toward the first airway 100 .

[0049] Specifically, the first bracket 4 may be a part of the battery rod assembly 2, or may be a part of the atomizer 1, or may be a common part of the battery rod assembly 2 and the atomizer 1. In some embodiments, the first bracket 4 may be a part of the battery bracket of the battery rod assembly 2, and a liquid reservoir 45 is provided at one end of the battery bracket close to the atomizer 1; in some other embodiments, the first bracket 4 may be the base of the atomizer 1, and a liquid reservoir 45 may be provided on one side of the base close to the first airway 100; or in the electronic atomization device, the battery bracket and the atomization bracket are integrally provided, and the first bracket 4 is a part thereof, and a liquid reservoir 45 may also be provided to surround the airway plug 3 and the periphery of the main body 31, and the opening of the liquid reservoir 45 is provided to face the first airway 100.

[0050] The liquid reservoir 45 can store the leaked liquid that flows downward from the first air channel 100 but does not flow toward the air flow channel 10 and the second air channel 20. For example, when the airway plug 3 is the main body 31, the liquid reservoir 45 can store the leaked liquid that flows along the liquid guide structure 311; when the airway plug 3 is the vent pipe 33, the connecting surface is the bottom of the liquid reservoir 45, and the liquid reservoir 45 can store the leaked liquid that flows downward along the outermost side of the vent pipe 33.

[0051] For further information, see Figure 1 , the battery rod assembly 2 includes a second bracket 21, the second bracket 21 is provided with at least one circuitous structure, and the second air channel 20 is formed in the circuitous structure. The second bracket 21 is a battery bracket. In some embodiments, for example, when the first bracket 4 includes a base portion enclosing a first sub-airflow channel, the base portion and the circuitous structure can be integrally formed or connected in parts; or when the first bracket 4 includes a first through hole 44, the first through hole 44 and the circuitous structure can be integrally formed or connected in parts; that is, the first bracket 4 can be a part of the second bracket 21, or the two can be two separate structures. After the two are assembled, the airflow channel 10 and the second airflow channel 20 can be connected, and the airflow can flow between the airflow channel 10 and the second airflow channel 20.

[0052] For further information, see Figure 1 In some embodiments, the second bracket 21 further comprises a stepped hole 211 extending radially, the stepped hole 211 is located at one end of the circuitous structure away from the airway plug 3, the second bracket 21 further comprises a microphone bin 212 for mounting a microphone, a notch 213 connecting the microphone bin 212 is formed on the side of the stepped hole 211 away from the airway plug 3, the electronic atomization device further comprises an oil-absorbing cotton 5, the oil-absorbing cotton 5 is assembled in the stepped hole 211 and is located on the side of the notch 213 away from the circuitous structure.

[0053] Specifically, the second bracket 21 is also provided with a stepped hole 211 perpendicular to the detour structure, and the stepped hole 211 is provided with a notch 213, so that the airflow can flow between the detour structure, the stepped hole 211 and the notch 213. Since the notch 213 is located at the end of the detour structure away from the airway plug 3, the airflow can flow through the notch 213 in the second airway 20 and the microphone chamber 212, so that the microphone can be started normally. In addition, oil-absorbing cotton 5 is provided in the stepped hole 211, and the oil-absorbing cotton 5 is provided on the side of the notch 213 away from the detour structure. With the stepped hole 211 close to the detour structure as the top, if the notch 213 is provided in the middle of the stepped hole 211, the oil-absorbing cotton 5 is provided on the bottom side of the stepped hole 211. Therefore, if there is leakage from the airflow channel 10 to the second airway 20, the oil-absorbing cotton 5 will absorb the leakage, thereby protecting the microphone from being damaged by the leakage, and having a further anti-leakage effect. It should be understood that the notch 213 can also be set at a position slightly above the middle or slightly below the middle of the stepped hole 211 , and the specific setting can be adaptively adjusted according to the size of the oil-absorbing cotton 5 and the number of steps of the stepped hole 211 .

[0054] For further information, see Figure 1 The atomizer 1 may also include a base silicone, which has a through hole connected to the first airway 100. If the leaked liquid leaks from the first airway 100, it first passes through the through hole of the base silicone and then flows to the airway plug 3, etc. Therefore, an annular groove may be provided on the side of the base silicone away from the first airway 100, and the annular groove is distributed around the through hole, so that the leaked liquid can be initially blocked here, and the initial leak-proof effect can be achieved. If the leaked liquid continues to spread downward, it will be further prevented from leaking through the airway plug 3, etc.

In summary, the content of this specification should not be understood as limiting the present invention.
