It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

They are only for convenience of description and do not indicate or imply the device to which they are referred. Or elements must have specific orientations, be constructed and operated in specific orientations, and therefore cannot be construed as limitations to the application. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances. The terms "first" and "second" are only used for convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of technical features.

In a traditional atomizer core, the heating wire is arranged in the atomization channel of the atomizer core. In terms of process selection, the pin of the heating wire can be welded to lead out the lead and then installed in the atomization channel; or, the lead is extended into the atomization channel and welded to the pin of the heating wire. For the former, the lead at the pin of the heating wire is prone to fall off during the assembly process. In order to solve the above problem, the heating element and the lead are usually sintered into one with the atomization carrier of the atomizer core. However, since the lead needs to pass through the atomization carrier and extend to the outside, the structural strength of the atomization carrier will be affected, such as the atomization carrier is prone to cracking. The lead on the pin also affects the assembly speed. Otherwise, the welding space is small, which increases the difficulty of welding, the degree of automation is low, and the production efficiency is difficult to improve.

Thus, the present application provides an atomizer core 100, in which the electrode portion 23 of the heating element 20 extends outside the atomization channel 10c, that is, the electrode portion 23 is exposed to the outside, thereby increasing the welding space and reducing the difficulty of welding and wiring.

Please refer to Figures 1 and 2. The atomizing core 100 in the embodiment of the present application includes an atomizing carrier 10 and a heating element 20. The atomization carrier 10 is used to supply atomization liquid such as oil liquid to adhere, and the heating element 20 generates heat due to the action of an external power supply to atomize the atomization liquid adhering to the surface of the atomization carrier 10 .

Specifically, the atomization carrier 10 has a first end 10a and a second end 10b. The atomization carrier 10 is provided with an atomization channel 10c that runs through the first end 10a and the second end 10b. The two first inner walls 10a are used for atomization. The projection on the cross-section of the channel 10c is a line segment arranged oppositely and parallelly. Among them, the atomization carrier 10 is assembled in the ventilation structure of the atomization device. Usually, the atomization carrier 10 has a cubic structure. In the use state, the first end 10a and the second end 10b of the atomization carrier 10 are in contact with the atomization device. On the end surface that is perpendicular to the flow direction of the gas, the first inner wall 10c1 and the second inner wall 10c2 of the atomization channel 10c can be selected to be parallel to the flow direction of the atomized gas.

At the same time, the structural form of the two second inner walls 10c2 can be selected. For example, the two second inner walls 10c2 can also be arranged in parallel. In this way, the atomization channel 10c is on a plane parallel to the first end 10a or the second end 10b. It is rectangular, which can cause the surface tension of atomized liquids such as oil to be inconsistent on the corresponding inner wall, thereby reducing the risk of blockage of the atomized channel 10c. Alternatively, the two second inner walls 10c2 can also be convex to the outside or concave to the inside. Similarly, it can cause the central axis of the atomization carrier 10 to be offset from the center of the atomization channel 10c, that is, each inner wall corresponding to Wall thickness varies.

The heating element 20 has two symmetrically arranged heating parts 21, a connecting part 22 connected to the same side of the two heating parts 21, and an electrode part 23 extending outward from the other side of the corresponding heating part 21. The two heating parts 21 are respectively arranged on the corresponding first inner wall 10c1. One end of the two electrode parts 23 away from the heating part 21 both extends from the atomization channel 10c to the outside. The electrode part 23 is used to connect with the external electrode. Here, the two heating parts 21 are in contact with the first inner wall 10c1, and their working heat is transferred to the inner wall of the atomization carrier 10 through the first inner wall 10c1. The connection part 22 connects the two heating parts 21 in series. The electrode part 23 is used to connect with the external power supply. At the same time, the outwardly extending portion of the electrode portion 23 is convenient for connecting peripheral leads or directly abutting the electrodes of the peripheral power supply.

The atomizing core 100 provided in this application has an atomizing channel 10c running through the first end 10a and the second end 10b in the middle of the atomizing carrier 10, and has an atomizing channel 10c parallel to the first end 10a or the second end 10b. In the plane, the cross section of the atomization channel 10c has two first inner walls 10c1 and two second inner walls 10c2 that are opposite and arranged in parallel. Among them, the two first inner walls 10c1 are provided for the two heating parts 21 of the heating element 20, and the connecting part 22 is located on one of the second inner walls 10c2, or suspended above the second inner wall 10c2, and will correspond to the heating part 21 The electrode part 23 extends outside the atomization channel 10c, so that the part of the electrode part 23 beyond the first end 10a or the second end 10b can be connected to the external power supply. Compared with the electrode part 23 located in the atomization channel 10c The wiring space of the electrode part 23 of the atomizing core 100 of the present application is larger, which is convenient for operation. Compared with the existing structure in which the heating element and the atomizing carrier are sintered into one body, the atomizing core 100 of the present application has It is possible to first sinter the heating element 20 and the atomization carrier 10 into one body, and then weld the electrode part 23 to the lead wire. The lead wire does not need to be sintered together with the heating element 20 and the atomization carrier 10 to reduce the impact of the lead wire on the atomization carrier 10. The influence of structural strength is conducive to simplifying the manufacturing process when the heating element 20 and the atomization carrier 10 are combined into one body, so as to reduce the overall manufacturing cost of the atomization core 100. When the atomization core 100 can be extended to the outside of the atomization channel 10c, The electrode part 23 is welded to the lead, and then connected to the electrode of the external power supply via the lead, or directly connected to the electrode of the external power supply through the electrode part 23. The electrical connection operation is convenient.

In one embodiment, the connecting portion 22 connecting the two heating portions 21 has an arc-shaped structure, so that the connecting portion 22 has telescopic deformation characteristics in the direction along the two first inner walls 10c1. At the same time, when the connecting portion 22 When placed in the atomization channel 10c in a compressed state, an outward force is exerted on the two heating parts 21, so that the heating parts 21 are in contact with the corresponding first inner wall 10c1, thereby improving the position of the heating element 20 in the atomization channel. The installation stability in 10c is that the heating element 20 can be detachably fixed in the atomization channel 10c through the elastic force of the connecting portion 22.

Of course, the heating element 20 can also be sintered as one body with the atomization carrier 10 in the atomization channel 10c.

In some embodiments, the heating element 10 is made of a metal sheet made of metal materials, including but not limited to titanium, nickel and their alloys, or other alloy materials, such as stainless steel. The atomization carrier 10 may be made of porous ceramics/porous glass or other porous materials, such as cotton, non-woven fabrics and composite materials thereof, but is not limited thereto.

Please refer to Figures 1 and 2. In one embodiment, the electrode part 23 includes a first electrode section 231 placed in the atomization channel 10c and a third electrode section 231 connected to the first electrode section 231 and placed outside the atomization channel 10c. The two electrode segments 232, the first electrode segment 231 and/or the second electrode segment 232 are used to connect with the electrodes of the external power supply. It can be understood that if the electrode part 23 is connected to the peripheral power supply through a lead, the peripheral lead can be provided on the first electrode section 231; or, it can be provided on the second electrode section 232; or, it can be provided on the first electrode section 231. and the connection with the second electrode segment 232; preferably, the lead is connected to the second electrode segment 232. If the electrode part 23 directly contacts the electrode of the external power supply, it may also choose to contact the first electrode segment 231; or contact the second electrode segment 232; or, contact the first electrode segment 231 and the second electrode segment 232 are in contact with each other. Preferably, the heating element 10 can be connected to the electrode of the external power supply through the second electrode section 232 extending outside the atomization channel 10c.

Here, the definition of the first electrode segment 231 and the second electrode segment 232 is the difference between the electrode part 23 inside and outside the atomization channel 10c. The electrode part 23 located inside the atomization channel 10c is the first electrode segment 231, and the electrode part 23 located outside the atomization channel 10c is the second electrode segment 232.

Please refer to FIGS. 2 and 3 . In one embodiment, the two second electrode segments 232 are bent outward and 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 bent outwardly and away from each other. The electrode segments 232 are simultaneously located at the end of the first end 10a or at the end of the second end 10b. It can be understood that after the second electrode segment 232 exposed outside the atomization channel 10c is bent, it contacts the first end 10a or the second end 10b, so that the electrodes of the external power supply can directly contact each other to achieve energization. At this time, the atomization carrier 10 plays a supporting role to prevent the second electrode segment 232 from deflecting during the contact process, and uses the contact and energization method to provide a structure for the plug-in connection of the peripheral power supply. conditions, so that it is convenient to replace the power supply later.

In one embodiment, the first end 10a or the second end 10b is provided with a groove structure for limiting the second electrode segment 232, that is, the groove structure is provided at the end where the second electrode segment 232 is located. It can be understood that in the direction of plugging and unplugging the peripheral power supply, the second electrode segment 232 is blocked by the first end 10a or the second end 10b of the atomizer carrier 10 and its position is limited. However, in order to prevent the peripheral power supply from being disconnected during the plugging process, , the second electrode segment 232 is deflected, and the groove structure is used to limit the deflection of the second electrode segment 232 in the plane where the first end 10a or the second end 10b is located. Here, the shape of the groove structure matches the shape of the second electrode segment 232 to limit the translation sliding of the second electrode segment 232 on the first end 10a or the second end 10b, thereby improving the atomization performance of the second electrode segment 232. The structural stability of the carrier 10 prevents problems such as separation from the atomization carrier 10 when external electrodes are brought into contact. In addition, when the second electrode segments 232 are respectively located in corresponding grooves, they can be separated from the atomization carrier 10 where they are located. The ends of 10 are flush to ensure the consistency of the overall appearance of the atomizer core.

It should be noted that, in other embodiments, the second electrode segment 232 may be partially embedded in the end of the atomization carrier 10 , partially protrude from the corresponding end of the atomization carrier 10 or be flush with the corresponding end, and this application does not make any specific limitation thereto.

Please refer to FIG. 3 . In one embodiment, the heating element 20 further includes a first embedded part 24 . The first embedded part 24 is provided on at least one heating part 21 . The first embedded part 24 is inserted into the first inner wall 10c1 or the third inner wall 10c1 . Second inner wall 10c2. It can be understood that the function of the first embedded part 24 is to increase the contact position between the heating part 21 and the atomization channel 10c, thereby improving the connection stability of the heating part 21 in the atomization channel 10c. At the same time, the first embedded part 24 also It has the function of transferring heat to the inside of the atomization carrier 10 , that is, the working heat of the heating element 20 can be transmitted to the inner wall of the atomization carrier 10 through the first embedded part 24 , thereby increasing the temperature rise rate of the atomization carrier 10 . Here, the material of the first embedded part 24 is not limited, and may be the same as or different from the material of the heating part 21. At the same time, the location of the first embedded part 24 is not limited. For example, a plurality of first embedded parts 24 are symmetrically provided on opposite sides of the heating part 21, and each first embedded part 24 can be selectively inserted into the first inner wall 10c1 or the second inner wall 10c2. In this way, the installation stability of the heating part 21 in the atomization channel 10c is higher. At the same time, the atomization carrier 10 can be heated as a whole. The first embedded part 24 can pre-heat the atomization medium in the atomization carrier 10. The effect of heat, for the viscous atomization medium, is to increase the temperature of the atomization medium through preheating, reduce its viscosity, increase the flow rate in the atomization carrier 10, and prevent the heating element 20 from being atomized When the atomization medium on the inner surface of the channel 10c is heated and atomized, due to the slow flow rate of the atomization medium, the atomization medium cannot be transported to the wall surface where the heating element 20 is located in time, causing the problem of dry burning of the heating element 20.

Please refer to Figure 3. In one embodiment, the heating element 20 further includes a second embedded portion 25. The second embedded portion 25 is provided on at least one electrode portion 23. The second embedded portion 25 is inserted into the first inner wall 10c1 or the second inner wall 10c2. It can be understood that the function of the second embedded portion 25 is to increase the force position of the electrode portion 23 and the atomization channel 10c, thereby improving the connection stability of the electrode portion 23 in the atomization channel 10c. At the same time, the electrode portion 23 can also generate heat after being energized. Then, the heat is transferred to the inside of the atomization carrier 10 through the second embedded portion 25, that is, the working heat generated by the electrode portion 23 can be transmitted to the inner wall of the atomization carrier 10 through the second embedded portion 25, thereby improving the heating rate of the atomization carrier 10. Here, the material of the second embedded portion 25 is not limited, and it can be the same as the material of the electrode portion 23, or it can be different. At the same time, the setting position of the second embedded portion 25 is also not limited. For example, a plurality of second embedded parts 25 are symmetrically arranged on opposite sides of the electrode part 23, and each second embedded part 25 can be selectively inserted into the first inner wall 10c1 or the second inner wall 10c2. When the second embedded part 25 is inserted into the second inner wall 10c2, it is straight, and when the second embedded part 25 is inserted into the first inner wall 10c1, it is folded outward, and its insertion direction forms an angle with the plane where the first inner wall 10c1 is located. In this way, the installation stability of the electrode part 23 in the atomization channel 10c is higher, and at the same time, the atomization carrier 10 can be heated as a whole.

In one embodiment, the heating part 21 has a sheet-like structure, the first inner wall 10c1 is a plane inner wall, and the heating part 21 is attached to the first inner wall 10c1. It can be understood that the heating part 21 with a sheet-like structure has a larger contact area with the in-plane arm, which is more suitable for the heating part 21 to transfer the working heat to the inside of the atomization carrier 10 .

Please refer to Figure 4. In one embodiment, the two second inner walls 10c2 are parallel, and on a cross-section parallel to the first end 10a or the second end 10b, the atomization channel 10c has a square structure, and the connecting portion 22 is adjacent to Closed to the first inner wall 10c1 and the second inner wall 10c2. It can be understood that the atomization channel 10c with a square cross-section structure can cause the central axis of the atomization carrier 10 to be offset from the center of the atomization channel 10c, that is, the corresponding wall thickness of each inner wall is different, and the atomization of oil, etc. The surface tension of the liquid on each inner wall is different, so it is not easy to block the atomization channel 10c, especially when the mobility of the atomization liquid is poor.

Please refer to FIG. 5 . In one embodiment, the two second inner walls 10c2 are both concave toward the outer wall of the atomization carrier 10 to form arc-shaped inner walls, and the connecting portion 22 is attached to the first inner wall 10c1 and the second inner wall 10c2 . It can be understood that the atomization channel 10c with an annular cross-section structure can also cause the central axis of the atomization carrier 10 to be offset from the center of the atomization channel 10c. That is, the corresponding wall thickness of each inner wall is different, and the oil and other mist The surface tension of the atomized liquid on each inner wall is different, so it is not easy to block the atomization channel 10c, especially when the atomized liquid has poor fluidity.

Please refer to Figures 8 and 9. In one embodiment, the connecting portion 22 spans across one end of the atomization channel 10c away from the electrode portion 23, and a gas hole 22a is provided on the connecting portion 22 for the atomization gas to pass through, or the connecting portion 22 is separated from the inner wall of the atomization channel 10c to form a gas gap.

It can be understood that in the initial non-assembled state, the heating element 20 has a sheet-like structure, which is convenient for manufacturing and determining the heating power of the heating element 20. The two heating parts 21 are respectively on opposite sides of the connecting part 22. In this way, the heating element 20 The whole structure is in the shape of a straight line. In the assembled state, the ends of the two heating parts 21 away from the connecting part 22 are bent toward each other, and the bending angle of the two heating parts 21 is adjusted according to the inclination of the inner wall of the atomization channel 10c. In some embodiments, the two heating parts 21 are parallel to each other and perpendicular to the connecting part 22 .

Since the connection part 22 spans the end of the atomization channel 10c away from the electrode part 23 and affects the flow of atomized gas through the atomization channel 10c, it is necessary to open an air hole 22a in the connection part 22. Here, the structural form of the air hole 22a is not limited, as long as the atomized gas can pass through. At the same time, providing the air holes 22a can also reduce the heating power of the connecting part 22 to improve the power utilization rate. Moreover, when the connecting part 22 is in a heating state, it can also continuously heat the atomized gas passing through it, maintain the temperature during the transmission process of the atomized gas, and reduce the probability of condensation of the atomized gas. In addition, when the atomized gas in the atomized channel 10c When the aerosol flows through the connecting part 22 , it releases heat due to heat transfer with external cold air or other components and forms condensate. Once the condensate adheres to the connecting part 22 , it can be heated again by the connecting part 22 Atomization further reduces the formation of condensate.

Of course, an air-passing gap may also be formed between the outer peripheral side of the connecting part 22 and the inner wall of the atomization channel 10c, that is, the atomized gas passes through the atomization channel 10c through the air-passing gap.

Specifically, as shown in FIG. 10 , a square air hole 22 a is opened in the connecting portion 22 . Alternatively, as shown in FIG. 12 , three racetrack-shaped air passage holes 22 a arranged in parallel are opened in the connecting portion 22 .

When it is necessary to explain, whether the number of air holes 22a is 1, 2, 3 or more, the shape of the air holes 22a can be a regular square (such as a square or a rectangle), or other polygons, such as a square. Triangles, regular pentagons, etc. can also be circular or elliptical, or other irregular shapes, which are not specifically limited in this application.

Please refer to Figure 11. In one embodiment, the connecting portion 22 is also provided with a plurality of liquid suction grooves 22b surrounding the periphery of the air hole 22a, and the liquid suction grooves are used to absorb condensate.

It can be understood that when the atomized gas encounters the connection part 22, condensation will occur. The liquid suction tank 22b can be used to adsorb the condensed atomization medium on the connection part 22, and when the temperature rises through the connection part 22, it will The atomized medium here atomizes and rises again.
