DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make a purpose, technical solutions, and advantages of the present disclosure clearer, the present disclosure will be further described in details below with reference to the accompanying drawings and embodiments. It should be understood that, the specific embodiments described herein are merely used for explaining the present disclosure, and are not intended to limit the present disclosure.
It should be noted that, when a part is referred to as being “fixed to” or “disposed on” another part, the part may be directly on another part or indirectly on another part. When a part is referred to as being “connected to” another part, it may be directly or indirectly connected to another part. Orientation or positional relationship indicated by terms “upper”, “lower”, “left”, “right”, and the like are based on the orientation or positional relationship shown in the accompanying drawings, and is merely for the convenience of description, rather than indicating or implying that an apparatus or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present disclosure. For those having ordinary skill in the art, a specific meaning of the above-mentioned terms may be understood according to a specific situation. Terms “first” and “second” are merely for the convenience of description, and cannot be understood as indicating or implying relative importance or implying the number of technical features. A meaning of “a plurality of” is two or more, unless specifically defined otherwise.
In a conventional atomization core, a heating wire is disposed in an atomization channel of an atomization core. In the process selection, a pin of the heating wire may be welded to a leading wire, and then be mounted in the atomization channel; or, the leading wire is inserted into the atomization channel to be welded to the pin of the heating wire. For the former, the leading wire at the pin of the heating wire is prone to detachment during an assembly process. In order to solve this problem, a heating element and the leading wire usually sinter into an integrated structure with an atomization carrier of the atomization core. However, because the lead is required to penetrate through the atomization carrier and extend to the outside, so that structural strength of the atomization carrier is affected, and thus the atomization carrier is prone to cracking, and the leading wire on the pin also affects an assembly speed. For the latter, a space for welding is narrow, so that welding difficulty is increased, and a level of automation is reduced, and thus a production efficiency is difficult to be improved.
Based on this, the present disclosure provides an atomization core, in which electrode parts of a heating element extends to the outside of an atomization channel, that is, the electrode parts are exposed to the outside, so that a welding space is increased, and thus difficulty of welding a leading wire is reduced.
Referring to FIG. 1 and FIG. 2 , an atomization core 100 according to an embodiment of the present disclosure includes an atomization carrier 10 and a heating element 20. The atomization carrier 10 is used for allowing an atomization liquid, such as oil to attach thereto, and the heating element 20 is heated under an action of an external power supply, to atomize the atomization liquid attaching to a surface of the atomization carrier 10.
Specifically, the atomization carrier 10 has a first end 10 a and a second end 10 b, the atomization carrier 10 is provided with an atomization channel 10 c penetrating through the first end 10 a and the second end 10 b, and projections of two first inner walls 10 cl on a cross section of the atomization channel 10 c are line segments arranged opposite to each other, for example, line segments arranged opposite and parallel to each other. The atomization carrier 10 is disposed in a ventilation structure of an atomization apparatus, and usually, the atomization carrier 10 has a cubic structure. In a using state, the first end 10 a and the second end 10 b of the atomization carrier 10 are end faces perpendicular to a flow direction of an atomization gas, and first inner walls 10 cl and second inner walls 10 c 2 of the atomization channel 10 c may be parallel to the flow direction of the atomization gas.
Meanwhile, structural forms of the two second inner walls 10 c 2 may be selected, for example, the two second inner walls 10 c 2 may also be arranged to parallel to each other, so that an orthographic projection of the atomization channel 10 c on a plane parallel to the first end 10 a or the second end 10 b is rectangular. The rectangle may cause surface tension on corresponding inner walls, of a atomization liquid, such as oil, and the like, to be inconsistent, to reduce a risk of blocking the atomization channel 10 c. Alternatively, the two second inner walls 10 c 2 may also be designed to protrude outwards or concave inwards, and similarly, this design may cause a central axis of the atomization carrier 10 to be offset from a center of the atomization channel 10 c, that is, a wall thickness corresponding to each wall is different.
If a distance from the central axis of the atomization channel to a wall thereof is the same at all positions (for example, when a cross section perpendicular to a central axis of the atomization channel, of the atomization channel, is circular), and especially when the central axis of the atomization channel coincides with a center line of the atomization carrier, the atomization liquid will be prone to forming a closed liquid film with balanced force distribution in the atomization channel, thereby causing blockage of the atomization channel.
By adjusting a structure of the atomization channel and/or distribution of the wall thickness of the atomization carrier, the distances from the central axis of the atomization channel to different positions of the wall thereof may be varied, so that the distances between an outer peripheral wall of the atomization carrier and the walls of the atomization channel are different. In this way, at least in a circumferential direction of the atomization carrier, there are differences between transference driving force or the transference amount of the atomization medium from the outer peripheral wall of the atomization carrier to the wall of the atomization channel, so that it is beneficial to reduce and prevent the atomization medium from forming a liquid film on the wall of the atomization channel, and thus splashing of a atomization medium is avoided, and the blockage of the atomization channel caused by low fluidity of the atomization medium is avoided.
The heating element 20 is provided with two heating parts 21 (for example, two symmetrically arranged heating parts 21), a connecting part 22 which is connected to a same side of the two heating parts 21, and electrode parts 23 which are extending outwards from the other side of the corresponding heating parts 21. The two heating parts 21 are respectively disposed on the corresponding first inner walls 10 c 1, an end of the electrode part 23 away from the heating part 21 extends out of the atomization channel 10 c, and the electrode parts 23 are used for being connected to an external electrode. Herein, the two heating parts 21 abut against the first inner walls 10 c 1, so that heat generated during working thereof is transferred to the wall of the atomization carrier 10 through the first inner walls 10 c 1. The two heating parts 21 are connected in series by the connecting part 22. The electrode parts 23 are used for connecting an external power supply. Meanwhile, the outwardly extending portion of the electrode parts 23 facilitates the connection with a peripheral leading wire or directly abutting against an electrode of the external power supply.
According to the atomization core 100 provided by the present disclosure, the atomization channel 10 c penetrating through the first end 10 a and the second end 10 b is provided in a middle portion of the atomization carrier 10. In a plane parallel to the first end 10 a or the second end 10 b, the cross section of the atomization channel 10 c is provided with two first inner walls 10 cl which are opposite (f) to each other, for example, opposite and parallel to each other, and two second inner walls 10 c 2. The two heating parts 21 of the heating element 20 are disposed on the two first inner walls 10 c 1, and the connecting part 22 is disposed on one of the second inner walls 10 c 2, or suspended above the second inner walls 10 c 2. The electrode parts 23 corresponding to the heating parts 21 extends out of the atomization channel 10 c. In this way, the portion of the electrode parts 23 extending beyond the first end 10 a or the second end 10 b may be connected to an external power supply. Compared with a structure in which electrode parts 23 are located in the atomization channel 10 c, the electrode parts 23 of the atomization core 100 of the present disclosure have a greater wiring space, so that it is convenient for operating. Compared with a structure in which a heating element sinters into an integrated structure with an atomization carrier in the related art, the atomization core 100 of the present disclosure may firstly sinter the heating element 20 into an integrated structure with the atomization carrier 10, and then the electrode parts 23 are welded to the leading wire, so that the leading wire does not need to sinter into an integrated structure with the heating element 20 and the atomization carrier 10, thereby reducing influence of the leading wire on the structural strength of the atomization carrier 10, and it is beneficial for simplifying a manufacturing process when the heating element 20 sinters into an integrated structure with the atomization carrier 10, and thus an overall production and manufacturing cost of the atomization core 100 is reduced. The atomization core 100 may be welded to the leading wire by the electrode parts 23 extending to the outside of the atomization channel 10 c, and then be connected to the electrode of the external power supply via the leading wire, or the atomization core 100 may be directly connected to the electrode of the external power supply directly via the electrode parts 23, so that an operation of the electrical connection is convenient.
In an embodiment, the connecting part 22 connecting the two heating parts 21 has an arc-shaped structure. In this way, the connecting part 22 have a characteristic of elastic deformation in a direction along the two first inner walls 10 c 1. Meanwhile, when the connecting part 22 is in a compressed state, and is placed in the atomization channel 10 c, it applies an outward force to the two heating parts 21, to make the heating parts 21 abut against the corresponding first inner walls 10 c 1, so that mounting stability of the heating element 20 in the atomization channel 10 c is improved. Among them, the heating element 20 may be detachably fixed in the atomization channel 10 c through an elastic force of the connecting part 22.
Certainly, the heating element 20 may also sinter into an integrated structure with the atomization carrier 10 in the atomization channel 10 c.
In some embodiments, the heating element 10 is a metal sheet made of a metal material, and the metal material includes but not limited to titanium, nickel and alloys thereof, or other alloy materials, such as stainless steel, and the like. A material of the atomization carrier 10 may be porous ceramic or porous glass, or other porous materials, such as cotton, non-woven fabric, and a composite material thereof, but it is not limited to these materials.
Referring to FIG. 1 and FIG. 2 , in an embodiment, the electrode parts 23 include a first electrode segment 231 disposed in the atomization channel 10 c, and a second electrode segment 232 which are connected to the first electrode segment 231 and disposed outside the atomization channel 10 c. The first electrode segment 231 and/or the second electrode segment 232 are used for being connected to an electrode of an external power supply. It may be understood that, if the electrode parts 23 are connected to the external power supply through an external leading wire, the external leading wire may be disposed on the first electrode segment 231, or, may be disposed on the second electrode segment 232, or, may be disposed at a position where the first electrode segment 231 and the second electrode segment 232 are connected. For example, the leading wire are connected to the second electrode segment 232. When the electrode parts 23 directly abut against the electrode of the external power supply, alternatively, the leading wire may abut against the first electrode segment 231, or abut against the second electrode segment 232, or, abut against the position where the first electrode segment 231 is connected to the second electrode segments 232. For example, the heating element 10 may be connected to the electrode of the external power supply by the second electrode segment 232 extending out of the atomization channel 10 c.
Herein, the distinction between the first electrode segment 231 and the second electrode segment 232 is defined by the position of the electrode parts 23 relative to the atomization channel 10 c. The electrode parts 23 disposed in the atomization channel 10 c is the first electrode segment 231, and the electrode parts 23 outside the atomization channel 10 c is the second electrode segment 232.
Referring to FIG. 2 and FIG. 3 , in an embodiment, the two second electrode segments 232 are bent outwards away from each other and abut against the first end 10 a or the second end 10 b, that is, the two second electrode segments 232 are both located at an end of the first end 10 a or an end of the second end 10 b. It may be understood that, the second electrode segments 232 exposed outside the atomization channel 10 c abut against the first end 10 a or the second end 10 b after being bent, to directly abut against the electrode of the external power supply to achieve electrical connection. At this point, the atomization carrier 10 serves to provide structural support to prevent the second electrode segments 232 from shifting in a process of abutting against. Moreover, by using an electrical connection manner by abutting against, a structural basis for the external power supply to connect through a plug-in and pull-out manner is provided. In this way, it is facilitating subsequent replacement of the power supply.
Referring to FIG. 13 , in an embodiment, the first end 10 a or the second end 10 b is provided with groove structures 10 d for limiting positions of the second electrode segments 232, that is, the groove structures 10 d are disposed at an end where the second electrode segments 232 is located. It may be understood that, in a plug-in/plug-out direction of the peripheral power supply, the second electrode segments 232 are positionally constrained by the first end 10 a or the second end 10 b of the atomization carrier 10. However, in order to prevent the second electrode segments 232 from shifting in a plug-in process of the external power supply, the groove structures 10 d are used for limiting shifting of the second electrode segments 232 in a plane where the first end 10 a or the second end 10 b is located. Herein, shapes of the groove structures 10 d are adapted to external shapes of the second electrode segments 232 to limit translational sliding of the second electrode segments 232 at the first end 10 a or the second end 10 b, so that the structural stability of the second electrode segments 232 on the atomization carrier 10 is improved, and thus the external electrode is prevented from detaching from the atomization carrier 10 when touching, and the like. In addition, when the second electrode segments 232 are located in the corresponding groove structures 10 d, the second electrode segments 232 may be flush with an end of the atomization carrier 10 where they are located, to ensure consistency of overall appearance of the atomization core.
It should be noted that, in some other embodiments, the second electrode segments 232 may be partially embedded into an end of the atomization carrier 10, and partially protrude from the corresponding end of the atomization carrier 10 or flush with the corresponding end, which is not specifically limited herein.
Referring to FIG. 3 , in an embodiment, the heating element 20 further includes first embedding parts 24, at least one of the heating parts 21 is provided with the first embedding parts 24, and the first embedding parts 24 are embedded into the first inner walls 10 cl or the second inner walls 10 c 2. It may be understood that, a function of the first embedding parts 24 is to increase the contact positions of the heating parts 21 in the atomization channel 10 c, so that the connection stability of the heating parts 21 in the atomization channel 10 c is improved. Meanwhile, the first embedding parts 24 also have a function of transferring heat to interior of the atomization carrier 10, that is, the heat generated by working of the heating element 20 may be transmitted to the wall of the atomization carrier 10 via the first embedding parts 24, so that a heating rate of the atomization carrier 10 is improved. Herein, a material of the first embedding parts 24 is not limited, and may be the same as or different from the material of the heating parts 21. At the same time, setting positions of the first embedding parts 24 is not limited. For example, several first embedding parts 24 are symmetrically provided at two opposite sides of each heating parts 21, and each first embedding part 24 is selectively embedded into either the first inner walls 10 cl or the second inner walls 10 c 2. In this way, the mounting stability of the heating parts 21 in the atomization channel 10 c is higher. Meanwhile, it enables overall heating of the atomization carrier 10. The first embedding parts 24 may preheat the atomization medium in the atomization carrier 10, for a viscous atomization medium, a temperature of the atomization medium is improved by preheating, so that a viscosity of the atomization medium is reduced, thereby a flow rate of the atomization medium in the atomization carrier 10 is improved, and thus the following issue is avoid: when the heating element 20 heats and atomizes the atomization medium on an inner wall surface of the atomization channel 10 c, because the flow rate of the atomization medium is slow, the atomization medium cannot be transferred to the wall surface where the heating element 20 is located in time, so that the heating element 20 experiences dry burning.
Referring to FIG. 3 , in an embodiment, the heating element 20 further includes second embedding parts 25, at least one of the electrode parts 23 is provided with the second embedding parts 25, and the second embedding parts 25 are embedded into the first inner walls 10 cl or the second inner walls 10 c 2. It may be understood that, a function of the second embedding parts 25 is to increase contact positions of the electrode parts 23 in the atomization channel 10 c, so that the connection stability of the electrode parts 23 in the atomization channel 10 c is improved. Meanwhile, the electrode parts 23 are capable of generating heat after being energized, and then the heat is transmitted to the interior of the atomization carrier 10 through the second embedding parts 25, that is, the heat generated by working of the electrode parts 23 may be transferred to the wall of the atomization carrier 10 through the second embedding parts 25, so that the heating rate of the atomization carrier 10 is improved. Herein, a material of the second embedding parts 25 is not limited, which may be the same as or different from the material of the electrode parts 23. For example, several second embedding parts 25 are symmetrically provided at two opposite sides of each electrode part 23, and each second embedding part 25 is selectively embedded into either the first inner walls 10 cl or the second inner walls 10 c 2. When the second embedding parts 25 are embedded into the second inner walls 10 c 2, the second embedding parts 25 are in a straight state, and when the second embedding parts 25 are embedded into the first inner walls 10 c 1, the second embedding parts 25 are folded outwards, and an insertion direction of the second embedding parts 25 forms an angle with a plane where the first inner wall 10 cl is located. In this way, the mounting stability of the electrode parts 23 in the atomization channel 10 c is higher, and meanwhile, it may also achieve overall heating of the atomization carrier 10.
In an embodiment, the heating element 20 further includes first embedding parts 24 and second embedding parts 25, at least one of the heating parts 21 is provided with the first embedding parts 24, and the first embedding parts 24 are embedded into the first inner walls 10 cl or the second inner walls 10 c 2. At least one of the electrode parts 23 is provided with the second embedding parts 25, and the second embedding parts 25 are embedded into the first inner walls 10 cl or the second inner walls 10 c 2.
In an embodiment, the heating parts 21 has a sheet-like structure, the first inner walls 10 cl are plane inner walls, and the heating parts 21 fit on the first inner walls 10 c 1. It may be understood that, the heating parts 21 with the sheet-shaped structure have a greater area in contact with the plane inner wall, and is more suitable for the heating parts 21 to transmit the heat generated by working to the interior of the atomization carrier 10.
Referring to FIG. 4 , in an embodiment, the two second inner walls 10 c 2 are parallel, and in a cross section parallel to the first end 10 a or the second end 10 b, the atomization channel 10 c has a square structure, and the connection part 22 fits on the first inner walls 10 cl and the second inner walls 10 c 2. It may be understood that, since the atomization channel 10 c has a square structure, the central axis of the atomization carrier 10 may be offset from the center of the atomization channel 10 c, that is, the wall thickness corresponding to each inner wall is different, so that the surface tension of the atomization liquid such as oil in each inner wall is different, and thus it is not easy to block the atomization channel 10 c, especially when the fluidity of the atomization liquid is poor.
Referring to FIG. 5 , in an embodiment, the two second inner walls 10 c 2 are both recessed towards the outer wall of the atomization carrier 10 or protrude from walls of the atomization carrier 10 to form an arc-shaped inner walls, and the connecting part 22 fit on the first inner walls 10 cl and the second inner walls 10 c 2. It may be understood that, an atomization channel 10 c, which has a cross section with a ring-shaped structure, a central axis of the atomization carrier 10 may also be offset from the center of the atomization channel 10 c, that is, the wall thickness corresponding to each inner wall is different, the surface tension of the atomization liquid such as oil in each inner wall is different, so that is not easy to block the atomization channel 10 c, especially when the fluidity of the atomization liquid is poor.
Referring to FIG. 8 and FIG. 9 , in an embodiment, the connecting part 22 spans across an end of the atomization channel 10 c away from the electrode parts 23, and the connecting part 22 is provided with a venthole 22 a for the atomization gas to pass through, or the connecting part 22 is spaced from the inner walls of the atomization channel 10 c and forms a gas passing gap.
It may be understood that, in an initial unassembled state, the heating element 20 has a sheet-shaped structure, which facilitates production and manufacturing and determining heating power of the heating element 20, and the two heating parts 21 are disposed at two opposite sides of the connecting part 22, respectively. In this way, the whole heating element 20 has a linear structure. In an assembling state, ends of the two heating parts 21 away from the connecting part 22 are bent towards each other. Bending angles of the two heating parts 21 are adjusted according to the inclination of the inner walls of the atomization channel 10 c. In some embodiments, the two heating parts 21 are parallel to each other and perpendicular to the connecting part 22.
Since the connecting part 22 spans across an end of the atomization channel 10 c away from the electrode parts 23, the flow of the atomization gas passing through the atomization channel 10 c is affected, and therefore, a venthole 22 a needs to be formed on the connecting part 22. A structure form of the venthole 22 a is not limited herein, as long as it allows the atomization gas to pass through. Meanwhile, the venthole 22 a may also reduce the heating power of the connecting part 22 to improve a power utilization rate. When the connecting part 22 is in the heating state, the atomization gas passing through the connecting part 22 may be continuously heated by the connecting part 22, the temperature of the atomization gas during a transmission process is maintained, so that condensation probability of the atomization gas is reduced. In addition, when aerosol in the atomization channel 10 c flows through the connecting part 22, the aerosol releases heat due to thermal exchange with external cold air or other parts, thereby forming condensate. Once the condensed liquid is attached to the connecting part 22, the condensed liquid may be heated by the connecting part 22 and will atomize again, so that the formation of the condensed liquid is further reduced.
Certainly, it is also possible that the outer peripheral side of the connecting part 22 is spaced from the inner wall of the atomization channel 10 c and forms a gas passing gap 22 c, that is, the atomization gas passes through the atomization channel 10 c through the gas passing gap 22 c.
Specifically, as shown in FIG. 10 , a square-shaped venthole 22 a is provided on the connecting part 22, or, as shown in FIG. 12 , the connecting part 22 is provided three with ventholes 22 a arranged in parallel in a racetrack shape.
It should be noted that, the number of the ventholes 22 a may be one, two, three or more, and the shapes of the venthole 22 a may be a regular square (such as a square or a rectangle), or may be other polygons, such as a regular triangle, a regular pentagon, or the like, or may be a circle or an ellipse, or may be other irregular shapes, which is not limited in the present disclosure.
Referring to FIG. 11 , in an embodiment, the connecting part 22 is further provided with a plurality of liquid absorbing grooves 22 b surrounding the venthole 22 a, and the liquid absorbing grooves are used for adsorbing condensate.
It may be understood that, when the atomization gas contacts with the connecting part 22, a condensation phenomenon may occur, and the atomization medium after condensation may be adsorbed on the connecting part 22 by using the liquid absorbing grooves 22 b. When the connecting part 22 heats up during operation, it will re-atomize the atomization medium on the connecting part 22.
In some embodiments, the liquid absorbing grooves 22 b may be capillary grooves. The capillary grooves are groove structures with a small size, and the atomization medium after condensation is adsorbed on the connecting part 22 due to a capillary adsorption force.
Referring to FIG. 14 , in an embodiment, the connecting part 22 spans across an end of the atomization channel 10 c away from the electrode parts 23. The connecting part 22 is provided with a venthole 22 a for the atomization gas to pass through, and the connecting part 22 is spaced from the inner wall of the atomization channel 10 c and to form a as passing gap 22 c.
Referring to FIG. 6 and FIG. 7 , in another embodiment, a same side of the two heating parts 21 are connected to a same side of the connecting part 22. Ends of the two heating parts 21 facing towards the connecting part 22 are bent towards each other, and then are disposed in the atomization channel 10 c. the connecting part 22 abuts against one of the second inner walls.
Similarly, in the initial unassembled state, the heating element 20 has a sheet-like structure, which facilitates production and manufacturing and determining the heating power of the heating element 20. The two heating parts 21 are disposed at the same side of the connecting part 22, separately, so that the heating element 20 has a U-shaped structure as a whole. In the assembled state, ends of the two heating parts 21 facing towards the connecting part 22 are bent toward each other, that is, they are bent relative to the connecting part 22, and the bending angle relative to the connecting part 22 is adjusted according to the inclination of the inner wall of the atomization channel 10 c. In some embodiments, the two heating parts 21 are parallel to each other, and the bent connecting part 22 fits on the second inner walls of the atomization channel 10 c to form an avoidance structure, to ensure that the atomization channel 10 c is unblocked.
Referring to FIG. 15 , an embodiment of the present disclosure further provides an atomization apparatus, and the atomization apparatus includes a bottom assembly 201, an oil storage assembly 202, a gas pipe 203, and the atomization core 100 above-mentioned. The bottom assembly 201 includes a base body 204 and electrode columns 205 disposed on the base body 204, and the oil storage assembly 202 is disposed on the base body 204. The gas pipe 203 is disposed in the liquid storage assembly (for example, an oil storage assembly 202).
