Description

Technical Field

[0001] This utility model belongs to the field of electronic atomization technology, and in particular relates to an atomizer and an electronic atomization device. Background Technology

[0002] Atomizers consist of an oil cup and an atomizing assembly. In related technologies, the atomizing assembly incorporates multiple layers of liquid guides. The atomized liquid in the oil cup flows through and is stored within these layers, preventing excessive liquid from flowing directly to the atomizer coil and causing leakage. This results in better oil retention and reduces leakage issues. However, due to the excessive number of liquid guides, not only does the atomized liquid need to flow through multiple layers, but the airflow also needs to pass through them. This can easily create negative pressure, hindering liquid flow and degrading the liquid delivery performance. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] Please see Figures 1 to 6 This utility model provides an atomizer, including a housing 1, a base 2, and an atomizing component 3. The base 2 is connected to one end of the housing 1. The atomizing component 3 is disposed inside the housing 1 and, together with the base 2 and the housing 1, forms a liquid storage chamber 100. The atomizing component 3 includes an outer cover 31, and a first liquid guide 32, an outer tube 33, a second liquid guide 34, an inner tube 35, and an atomizing core 36, which are disposed inside the outer cover 31 and sequentially connected radially from the outside to the inside. The outer cover 31 is provided with a connection between the liquid storage chamber 100 and the first liquid guide 36. The liquid inlet 11 of the liquid guide 32; a liquid inlet gap 320 is formed between one end of the first liquid guide 32 along the axial direction of the atomizer and the base 2, which is connected to the liquid inlet 11; the outer tube 33 is provided with a first return air groove 332 and a first liquid guide port 331 connecting the first liquid guide 32 and the second liquid guide 34, and the inner tube 35 is provided with a second return air groove 352 and a second liquid guide port 351 connecting the atomizing core 36 and the second liquid guide 34; the first return air groove 332, the second return air groove 352 and the liquid inlet gap 320 are correspondingly arranged.

[0037] In this embodiment of the invention, the atomizing component 3 adopts a structure in which an outer cover 31, a first liquid guide 32, an outer tube 33, a second liquid guide 34, an inner tube 35, and an atomizing core 36 are arranged radially in sequence, so that the atomizing component 3 includes multiple layers of liquid guides, thus achieving a better oil-locking effect. In addition, a liquid inlet 11 is provided in the outer cover 31, and a liquid inlet gap 320 is also provided between the first liquid guide 32 and the base 2. Air return grooves are respectively provided in the outer tube 33 and the inner tube 35, and the liquid inlet gap 320 and the air return groove are correspondingly arranged. In this way, external air can pass through the second air return groove 352, the second liquid guide 34, the first air return groove 332, the first liquid guide 32, the liquid inlet gap 320, and the liquid storage chamber 100 in sequence to form a stepped air exchange path, thereby balancing the internal and external air pressure, reducing the internal liquid guide resistance, and ensuring smooth oil flow and stability during use.

[0038] It should be noted that this utility model has undergone reliability testing on the atomizer, including filling with oil for 30 seconds, lubricating the coil for 3 minutes, and exhibiting no burnt taste or oil leakage during inhalation, indicating that the atomizer is reliable.

[0039] For example, such as Figure 2 As shown, the axial direction is parallel to the X-axis.

[0040] Furthermore, in some embodiments, the liquid inlet 11 is disposed on the outer cover 31 and is opposite to the end of the first liquid guide 32 that is axially close to the base 2.

[0041] Specifically, the first liquid guide 32 has an inlet gap 320 with the base 2 at one end along the axial direction. The inlet 11 on the outer cover 31 can be set opposite to the inlet gap 320. In this way, the liquid inlet process can be better realized, and the air exchange process can also be better realized.

[0042] Furthermore, during the liquid guiding process, the atomizing liquid can flow from the inlet 11 to the first liquid guide 32, then through the first liquid guide port 331 to the second liquid guide 34, and finally through the second liquid guide port 351 to the atomizing core 36. In other words, the atomizing liquid can circulate between the liquid guides via the liquid guide ports. During the ventilation process, external air can sequentially pass through the second return air groove 352, the second liquid guide 34, the first return air groove 332, the first liquid guide 32, the inlet gap 320, and the storage chamber 100, forming a stepped ventilation path. This balances the internal and external air pressure, reduces internal liquid guiding resistance, and ensures smooth and stable oil flow during use.

[0043] In some embodiments, the first return air groove 332 extends axially and is connected to the first liquid guide port 331. The first return air groove 332 and the first liquid guide port 331 are both provided on the outer tube 33 and are connected to each other. In this way, air exchange and liquid guidance can be carried out in an orderly manner in the second liquid guide 34. The first return air groove 332 provides air exchange for the second liquid guide 34, and the atomized liquid can be quickly guided to the second liquid guide 34.

[0044] In some specific embodiments, the first return air groove 332 can be mainly elongated, the first return air groove 332 is parallel to the axial direction, and the first return air groove 332 can be connected to one end of the first liquid guide port 331 along the axial direction, thereby realizing the connection between the first return air groove 332 and the first liquid guide port 331, and realizing the orderly operation of air exchange and liquid guide in the second liquid guide 34.

[0045] In some embodiments, the second air return groove 352 extends axially and communicates with the second liquid guide port 351. Both the second air return groove 352 and the second liquid guide port 351 are disposed in the inner tube 35 and communicate with each other, so that air exchange and liquid guidance can be carried out in an orderly manner in the atomizing core 36, the second air return groove 352 provides air exchange for the atomizing core 36, and the atomizing liquid can be quickly guided to the atomizing core 36.

[0046] In some specific embodiments, the second return air groove 352 can be mainly elongated, the second return air groove 352 is parallel to the axial direction, and the second return air groove 352 can be connected to one end of the second liquid guide port 351 along the axial direction, thereby realizing the connection between the second return air groove 352 and the second liquid guide port 351, and realizing the orderly operation of air exchange and liquid guide in the atomizing core 36.

[0047] In some embodiments, the first return air groove 332 extends axially and is connected to the first liquid guide port 331; simultaneously, the second return air groove 352 extends axially and is connected to the second liquid guide port 351. This allows for the orderly exchange of air and liquid guide in the second liquid guide 34, and similarly, the orderly exchange of air and liquid guide in the atomizing core 36 can be achieved, which will not be elaborated further here.

[0048] In some specific embodiments, the flow cross-sections of the first return air groove 332 and the second return air groove 352 are much smaller than the flow cross-sections of the first liquid guide port 331 and the second liquid guide port 351, so that the return air groove can be used entirely for air exchange, and the liquid guide port can also be used for smooth liquid guidance, avoiding mutual interference between the air exchange and liquid guidance processes.

[0049] Furthermore, in some embodiments, the density of the first conductive liquid 32 is less than the density of the second conductive liquid 34. Specifically, the first conductive liquid 32 can be a low-density conductive liquid, and the second conductive liquid 34 can be a high-density conductive liquid. Radially, the first conductive liquid 32 is closer to the liquid storage cavity 100. Therefore, the low density of the first conductive liquid 32 allows for better liquid penetration and diffusion, ensuring a better liquid transport effect. The second conductive liquid 34 is farther from the liquid storage cavity 100. Therefore, in addition to transporting liquid to the atomizing core 36, the second conductive liquid 34 also needs to have a certain oil-locking ability. By setting the density of the second conductive liquid 34 to be higher, a good oil-locking effect can be achieved while ensuring smooth liquid transport.

[0050] Furthermore, in some embodiments, the thickness of the first liquid guide 32 in the radial direction is less than the thickness of the second liquid guide 34 in the radial direction. Radially, the first liquid guide 32 is closer to the liquid storage cavity 100; therefore, its smaller thickness allows for better liquid penetration and diffusion, ensuring a better liquid transport effect. The second liquid guide 34, being farther from the liquid storage cavity 100, needs to not only transport liquid to the atomizing core 36 but also possess a certain oil-locking ability. By setting the thickness of the second liquid guide 34 to be greater, a good oil-locking effect can be achieved while ensuring smooth liquid transport.

[0051] Furthermore, in some embodiments, the density of the first conductive liquid 32 is less than the density of the second conductive liquid 34, and the thickness of the first conductive liquid 32 in the radial direction is less than the thickness of the second conductive liquid 34 in the radial direction. In this way, the functions of the first conductive liquid 32 and the second conductive liquid 34 can be better utilized, and a good oil-locking effect can be achieved while ensuring a good liquid transmission effect.

[0052] Furthermore, the wall thickness of the outer tube 33 is a in the radial direction; a first liquid guide 32 is provided on the outer side of the outer tube 33, and a second liquid guide 34 is provided on the inner side of the outer tube 33; both the first liquid guide 32 and the second liquid guide 34 can be flexible liquid guides.

[0053] In some embodiments, the first liquid guide 32 or the second liquid guide 34 has a first interference fit amount b with the outer tube 33, where b > a. Thus, there is an interference fit amount ba between the first liquid guide 32 and the second liquid guide 34, thereby forming an oil guide bridge between the first liquid guide 32 and the second liquid guide 34. Compared with the multi-layer liquid guide structure in the related art, where there is a distance of one tube wall thickness between adjacent liquid guide layers, the interference fit between the first liquid guide 32, the tube wall of the outer tube 33, and the second liquid guide 34 in this embodiment of the present invention allows the atomizing liquid to be quickly introduced from the first liquid guide 32 to the second liquid guide 34, thereby improving the liquid guiding effect between the first liquid guide 32 and the second liquid guide 34.

[0054] In some embodiments, the first liquid guide 32, the second liquid guide 34 and the outer tube 33 have a first interference fit amount b, wherein b > a.

[0055] Specifically, the first liquid guide 32 and the second liquid guide 34 can simultaneously have an interference fit with the wall of the outer tube 33. The sum of the interference fit between the first liquid guide 32 and the outer tube 33 and the interference fit between the second liquid guide 34 and the outer tube 33 can be the first interference fit amount b. Since b > a, there is an interference fit ba between the first liquid guide 32 and the second liquid guide 34. Similarly, an oil bridge can be formed between the first liquid guide 32 and the second liquid guide 34, which can improve the liquid guiding effect. This will not be elaborated here.

[0056] Understandably, the interference fit between the first liquid guide 32 and the outer tube 33, and the interference fit between the second liquid guide 34 and the outer tube 33 can be the same or different, and can be set according to the actual situation.

[0057] Furthermore, in some embodiments, the atomizing core 36 includes a heating element 361 and a third liquid guide 362 wrapped around the outside of the heating element 361. At least one of the second liquid guide 34 and the third liquid guide 362 is a flexible liquid guide. In the radial direction, the second interference fit c between the flexible liquid guide and the inner tube 35 is greater than the wall thickness d of the inner tube 35. Specifically, in the radial direction, the second liquid guide 34 is disposed on the outer side of the inner tube 35, and the third liquid guide 362 is disposed on the inner side.

[0058] In some implementations, the second liquid guide 34 or the third liquid guide 362 has a second interference fit amount c with the inner tube 35. Since the second interference fit amount c is greater than the wall thickness d of the inner tube 35, there is an interference fit of cd between the second liquid guide 34 and the third liquid guide 362, thereby forming an oil guide bridge between the second liquid guide 34 and the third liquid guide 362. Compared with the multi-layer liquid guide structure in related technologies, where there is a distance of one tube wall thickness between adjacent liquid guide layers, the interference fit between the second liquid guide 34, the tube wall of the inner tube 35, and the third liquid guide 362 in this embodiment of the present invention allows the atomizing liquid to be quickly introduced from the second liquid guide 34 to the third liquid guide 362, thereby achieving the purpose of rapid wick lubrication.

[0059] In some possible implementations, the second liquid guide 34, the third liquid guide 362, and the inner tube 35 have a second interference fit amount c. That is, the second liquid guide 24 and the third liquid guide 362 can simultaneously have an interference fit with the inner tube 35. The sum of the interference fit amount between the second liquid guide 24 and the inner tube 35 and the interference fit amount between the third liquid guide 362 and the inner tube 35 can be the second interference fit amount c. Since the second interference fit amount c is greater than the wall thickness d of the inner tube 35, there is an interference fit amount cd between the second liquid guide 34 and the third liquid guide 362. This can also form an oil guide bridge between the second liquid guide 34 and the third liquid guide 362, which can improve the liquid guiding effect. This will not be elaborated further here.

[0060] Understandably, the interference fit between the second liquid guide 34 and the inner tube 35, and the interference fit between the third liquid guide 362 and the inner tube 35 can be the same or different, and can be set according to the actual situation.

[0061] Furthermore, in some embodiments, the first liquid guide 32, the second liquid guide 34, and the third liquid guide 362 are all oil-guiding cotton, and the fiber direction of at least one of the first liquid guide 32 and the second liquid guide 34 extends along the axial direction of the atomizer. In this way, the atomizing liquid can be rapidly guided along the axial direction.

[0062] In some specific embodiments, the atomizing component 3 further includes a liquid inlet 11 opened on the side of the outer cover 31 away from the base 2 along the axial direction. The projection surface of the liquid inlet 11 along the axial direction falls into the first liquid guide 32. The first liquid guide 32 is oil-guiding cotton, and the fiber direction of the first liquid guide 32 is parallel to the axial direction. In this way, when the liquid storage chamber 100 is full of oil, the flow direction of the atomizing liquid can be parallel to the fiber direction of the first liquid guide 32, thereby achieving rapid oil guiding when the liquid is full.

[0063] Furthermore, in some embodiments, the base 2 is provided with a first assembly groove 21 with an opening facing the atomizing component 3, and the outer cover 31 passes through the first assembly groove 21. The first assembly groove 21 has a clearance opening 211 that connects the liquid storage chamber 100 and the liquid inlet 11. In this way, the base 2 and the outer cover 31 can be assembled and connected. The atomizing liquid in the liquid storage chamber 100 can flow through the clearance opening 211 of the first assembly groove 21 to the liquid inlet 11, and then to the liquid inlet gap 320 to flow to the first liquid guide 32, thereby realizing the conduction of the atomizing liquid.

[0064] In some specific embodiments, the outer cover 31 has a plurality of spaced liquid inlets 11 along the circumferential direction. Correspondingly, the first assembly groove 21 has a relief opening 211 that corresponds one-to-one with the liquid inlets 11 along the circumferential direction. In this way, the liquid inlet path of the atomizing liquid can be dispersed, making the atomizing liquid of the first liquid guide 32 more uniform and improving the liquid transmission effect of the first liquid guide 32.

[0065] Furthermore, in some embodiments, the side of the first assembly groove 21 away from the opening is provided with at least two abutting protrusions 212 arranged circumferentially, and the first liquid guide 32 abuts against the abutting protrusions 212, so that a liquid inlet gap 320 is formed between the side of the first assembly groove 21 away from the opening and the first liquid guide 32.

[0066] Specifically, the opening of the first assembly groove 21 faces the atomizing component 3. The bottom side of the first assembly groove 21 can be provided with multiple abutting protrusions 212. The outer cover 31 of the atomizing component 3 is disposed in the first assembly groove 21, and the first liquid guide 32 is disposed in the outer cover 31. That is to say, the first liquid guide 32 is also disposed in the first assembly groove 21. The first liquid guide 32 can abut against the abutting protrusions 212 on the bottom side of the first assembly groove 21. In this way, there is a gap between the first liquid guide 32 and the bottom side of the first assembly groove 21, and there is also a gap between two adjacent abutting protrusions 212, thereby defining the liquid inlet gap 320, so as to realize the liquid guiding and air exchange process.

[0067] Furthermore, in some embodiments, a second assembly groove 22 communicating with the first assembly groove 21 is provided on the side away from the opening of the first assembly groove 21, and one end of the outer tube 33 extends axially to the second assembly groove 22, and the outer side of the outer tube 33 abuts against the side wall of the second assembly groove 22.

[0068] Specifically, with the atomizing component 3 on top and the base 2 on the bottom, the opening of the first assembly groove 21 faces upward. A second assembly groove 22 that connects to the first assembly groove 21 can also be opened on the bottom side of the first assembly groove 21. In this way, the outer side of the end of the outer tube 33 away from the opening can abut against the side wall of the second assembly groove 22, so that the outer tube 33 and the base 2 can be assembled and connected.

[0069] In some specific embodiments, the first liquid guide 32 and the outer cover 31 extend to the first assembly groove 21, and the outer tube 33 and the second liquid guide 34 extend to the second assembly groove 22. Thus, the outer cover 31 is clamped between the first assembly groove 21 and the first liquid guide 32. At the same time, the outer side of the outer tube 33 abuts against the first liquid guide 32 along the axial direction and another part abuts against the second assembly groove 22. The outer tube 33 is clamped between the first liquid guide 32 and the second liquid guide 34 along the axial direction, and another part of the outer tube 33 is clamped between the second assembly groove 22 and the second liquid guide 34 along the axial direction. In this way, the outer cover 31 and the base 2 can be assembled and connected, the outer cover 31, the first liquid guide 32, the outer tube 33 and the second liquid guide 34 can be assembled and connected, and the outer tube 33 and the base 2 can be assembled and connected.

[0070] In some specific embodiments, the abutment protrusion 212 is disposed on the bottom side of the first assembly groove 21 and surrounds the second assembly groove 22. The outer tube 33 can extend to the bottom side of the second assembly groove 22, and the bottom side of the second assembly groove 22 can support the bottom side of the outer tube 33, thereby improving the connection stability of the outer tube 33. The first liquid guide 32 can extend to the abutment protrusion 212, and the liquid inlet gap 320 between the first liquid guide 32 and the base 2 is achieved through the abutment protrusion 212.

[0071] Furthermore, in some embodiments, a third assembly groove 23 communicating with the second assembly groove 22 is provided on the side away from the opening of the second assembly groove 22, one end of the inner tube 35 extends to the third assembly groove 23 along the axial direction, and the outer side of the inner tube 35 abuts against the side wall of the third assembly groove 23.

[0072] Specifically, with the atomizing component 3 on top and the base 2 on the bottom, the opening of the first assembly groove 21 faces upward, and a third assembly groove 23 communicating with the second assembly groove 22 can be opened on the bottom side of the second assembly groove 22. In this way, the outer side of the end of the inner tube 35 away from the opening can abut against the side wall of the third assembly groove 23, so that the inner tube 35 and the base 2 can be assembled and connected.

[0073] In some specific embodiments, the first liquid guide 32 and the outer cover 31 extend to the first assembly groove 21, the outer tube 33 and the second liquid guide 34 extend to the second assembly groove 22, and the inner tube 35 and the atomizing core 36 extend to the third assembly groove 23. Thus, the outer cover 31 is clamped between the first assembly groove 21 and the first liquid guide 32. Simultaneously, the outer side of the outer tube 33 abuts against the first liquid guide 32 along its axial direction, and another portion abuts against the second assembly groove 22. The outer tube 33 is clamped between the first liquid guide 32 and the second liquid guide 34 along its axial direction, and another portion of the outer tube 33 is clamped between the second assembly groove 22 and the second liquid guide 34 along its axial direction. The inner tube 35 is positioned between the second liquid guide 34 and the third assembly groove 23. The outer axial portion of the inner tube 35 abuts against the second liquid guide 34, and the other portion abuts against the third assembly groove 23. The inner tube 35 is sandwiched between the second liquid guide 34 and the atomizing core 36, and the inner tube 35 is sandwiched between the third assembly groove 23 and the atomizing core 36. This allows for the assembly connection of the outer cover 31 and the base 2, the assembly connection of the outer tube 33 and the base 2, the assembly connection of the outer cover 31, the first liquid guide 32, the outer tube 33, the second liquid guide 34 and the atomizing core 36, and the assembly connection of the inner tube 35 and the base 2.

[0074] Furthermore, a second aspect of the present invention provides an electronic atomizing device, including a battery rod assembly and an atomizer.

[0075] In this embodiment of the invention, the atomizing component 3 adopts a structure in which an outer cover 31, a first liquid guide 32, an outer tube 33, a second liquid guide 34, an inner tube 35, and an atomizing core 36 are arranged radially in sequence, so that the atomizing component 3 includes multiple layers of liquid guides, thus achieving a better oil-locking effect. In addition, a liquid inlet 11 is provided in the outer cover 31, and a liquid inlet gap 320 is also provided between the first liquid guide 32 and the base 2. Air return grooves are respectively provided in the outer tube 33 and the inner tube 35, and the liquid inlet gap 320 and the air return groove are correspondingly arranged.
