[0045] During the use of an atomizing device, the medium is inserted into the device and heated by its heating element. The medium releases as an aerosol through low-temperature heating without combustion. The heating element is typically electrically heated. In related technologies, the heating element usually includes a heating element and a medium container. The heating element is located inside the medium container. During use, the medium is inserted from one end of the medium container, and the heating element heats the medium.

[0046] Because the heating element and the dielectric container are in contact, the area of ​​the dielectric container in contact with the heating element is also heated during operation, resulting in a higher temperature and a significant temperature difference between this area and the non-contact areas. After the heating element has been used for a period of time, localized areas of the dielectric container are more prone to cracking due to repeated heating, thus affecting the service life of the heating element.

[0047] Figure 1 This is a schematic diagram of the structure of a heating component provided in an embodiment of this application, such as... Figure 1 As shown, the heating assembly includes a dielectric container 10, a heating element 30, and multiple leads 40. Figure 2 This is a schematic diagram of the internal structure of a heating component provided in an embodiment of this application. Figure 2 The medium into which the heating element is inserted is schematically shown using dashed lines. (For example...) Figure 2 As shown, one end of the medium container 10 is closed, and the other end of the medium container 10 has an inlet 10a.

[0048] The heating element 30 is located in the medium container 10. The heating element 30 is cylindrical, and one end of the heating element 30 faces the inlet 10a.

[0049] The lead wire 40 passes through the side wall of the dielectric container 10 and is fixedly connected to the side wall of the dielectric container 10. One end of the lead wire 40 inside the dielectric container 10 is connected to the heating element 30, and the other end of the lead wire 40 outside the dielectric container 10 is used to connect to the power supply. The heating element 30 is suspended in the dielectric container 10 by the support of multiple leads 40.

[0050] By placing the heating element 30 inside the medium receiving cylinder 10, with one end of the heating element 30 facing the inlet 10a, the medium inserted into the medium receiving cylinder 10 through the inlet 10a can be inserted into the heating element 30. A lead wire 40 is provided, penetrating the side wall of the medium receiving cylinder 10, and fixedly connected to the side wall of the medium receiving cylinder 10. The end of the lead wire 40 inside the medium receiving cylinder 10 is connected to the heating element 30. The lead wire 40 supports the heating element 30, suspending it within the medium receiving cylinder 10. This prevents the heating element 30 from directly contacting the medium receiving cylinder 10, thus preventing excessively high temperatures in localized areas of the medium receiving cylinder 10 during heating, which could cause cracking and extend the service life of the heating assembly.

[0051] Furthermore, since the heating element 30 is suspended in the medium container 10 via the lead wire 40, if the heating element 30 is damaged, the connection between the lead wire 40 and the heating element 30 can be cut, the heating element 30 can be removed, a new heating element 30 can be inserted, and the lead wire 40 can be connected to the new heating element 30. Compared to the heating element 30 being directly fixed to the medium container 10, the method of suspending the heating element 30 with the lead wire 40 eliminates the need to damage the medium container 10 when replacing the heating element 30.

[0052] The heating element may also include a support ring 20, which is connected to the inlet 10a. The support ring 20 has an air inlet channel 20a that connects the interior of the medium container 10 to the outside.

[0053] The support ring 20 is connected to the medium container 10, forming a cavity inside the medium container 10. The outside of this cavity is referred to as the outside of the cavity. During the use of the atomizing device, the medium can be inserted into the cavity through the support ring 20, and outside air can enter the cavity through the air inlet channel 20a.

[0054] For example, one side of the support ring 20 may have an annular insertion groove 20b, and the side wall of the medium receiving cylinder 10 may be inserted into the annular insertion groove 20b.

[0055] By connecting a support ring 20 at the inlet 10a of the medium container 10, the medium can be inserted into the medium container 10 through the support ring 20. The support ring 20 limits and supports the medium, which can prevent the medium from tilting and affecting the stability of the heating element 30, such as causing the heating element 30 to loosen or even become detached from the lead wire 40.

[0056] In some examples, a reflective layer is provided on the surface of the medium container 10. The reflective layer may be located on the inner wall or the outer wall of the medium container 10, or on both the inner and outer walls of the medium container 10.

[0057] The reflective layer can be a film layer that can reflect thermal radiation, such as a silver plating layer, or other coatings that have the ability to reflect thermal radiation.

[0058] By providing a reflective layer on the surface of the medium container 10, the impact of heat on the medium container 10 can be reduced, and the thermal expansion of the medium container 10 can be decreased, thereby further reducing the risk of cracking of the medium container 10 and helping to extend the service life of the heating element. The reflective layer located on the inner surface of the medium container 10 can also reflect the heat radiation generated by the heating element 30 towards the center of the medium container 10, improving the heating effect on the medium.

[0059] like Figure 2 As shown, the heating element 30 can be arranged coaxially with the support ring 20, and the inner diameter of the heating element 30 is larger than the inner diameter of the support ring 20.

[0060] The inner diameter of the support ring 20 limits the diameter of the medium that can be inserted into the heating element and also limits the insertion of the medium to prevent it from tilting. Since the inner diameter of the heating element 30 is larger than that of the support ring 20, the heating element 30 does not come into contact with the medium when it is inserted into the heating element. This avoids the medium exerting force on the heating element 30 during insertion or removal, reduces the risk of breakage at the connection between the heating element 30 and the lead wire 40, and ensures that the heating element 30 remains stable and does not loosen even when suspended.

[0061] like Figure 2 As shown, there may be a gap between the outer wall of the heating element 30 and the inner wall of the medium container 10. The outlet of the air inlet channel 20a is directly opposite the gap between the outer wall of the heating element 30 and the inner wall of the medium container 10. That is, the distance from the outlet of the air inlet channel 20a to the center of the support ring 20 is less than the inner radius of the medium container 10 and greater than the inner radius of the support ring 20.

[0062] The function of the air intake channel 20a is to allow outside air to enter the medium container 10 during the suction process. The inlet of the air intake channel 20a can be located on the side of the support ring 20 away from the medium container 10, and the outlet of the air intake channel 20a can be located on the side of the support ring 20 closer to the medium container 10.

[0063] The outlet of the air inlet channel 20a is directly opposite the gap between the outer wall of the heating element 30 and the inner wall of the medium container 10, allowing air entering from the outside to directly enter the gap between the outer wall of the heating element 30 and the inner wall of the medium container 10, and then enter the heating element 30 from the end away from the support ring 20, where it is drawn out along with the aerosol released by the medium. As the air flows through the gap between the outer wall of the heating element 30 and the inner wall of the medium container 10, it not only carries away some of the heat from the medium container 10, cooling it, but also preheats the air using the heat.

[0064] In some examples, the support ring 20 may have multiple air intake channels 20a, which are arranged at equal angular intervals along the circumference of the support ring 20.

[0065] For example Figure 2 As shown, the support ring 20 can have two air intake channels 20a, and the two air intake channels 20a can be arranged at a 180° interval.

[0066] The multiple air intake channels 20a arranged at equal angles allow air to enter the gap between the outer wall of the heating element 30 and the inner wall of the medium container 10 more evenly, making the air velocity difference in different parts of the gap smaller, thus carrying away the heat of the medium container 10 more evenly, and the preheating of the airflow is also more uniform.

[0067] In some examples, the support ring 20 can be a rubber ring or a plastic ring, which is not only easy to process, but also has good thermal insulation properties.

[0068] like Figure 2 As shown, the interior of the medium container 10 may have a limiting protrusion 11, which is located at the closed end of the medium container 10 and inside the orthographic projection of the support ring 20 at the closed end of the medium container 10.

[0069] When the medium is inserted into the heating element, the limiting protrusion 11 can support and limit the end of the medium, preventing the medium from directly contacting the closed end of the medium receiving cylinder 10 and affecting the airflow into the medium.

[0070] For example, there may be multiple limiting protrusions 11, which are spaced apart at the bottom of the medium receiving cylinder 10.

[0071] As an example, the bottom of the medium container 10 may be provided with two limiting protrusions 11, which are arranged symmetrically about the axis of the medium container 10.

[0072] In some examples, the lead 40 is fused or brazed to the sidewall of the medium container 10.

[0073] By using a fusion sealing method to embed the lead wire 40 in the medium container 10 and tightly connect it with the medium container 10, the lead wire 40 can be prevented from loosening, and air leakage from the side wall of the medium container 10 can also be prevented.

[0074] By connecting the lead wire 40 to the medium container 10 through brazing and sealing it, the loosening of the lead wire 40 can be prevented, thus preventing air leakage from the side wall of the medium container 10. The brazing process is relatively simple and easy to manufacture.

[0075] As an example, when processing the medium container 10, a through hole 10b can be formed in the side wall of the medium container 10, and then the lead wire 40 can be passed through the through hole 10b and then sealed by fusion or brazing, so that the lead wire 40 is connected to the side wall of the medium container 10 as a whole.

[0076] In some examples, the lead 40 can be Kovar alloy wire or Invar alloy wire. The dielectric container 10 can be a silicate glass container.

[0077] The thermal expansion coefficients of Kovar alloy wire and Invar alloy wire are very close to those of silicate glass tube. After the lead wire 40 is connected to the medium container 10 as a whole, the connection between the lead wire 40 and the medium container 10 is not easy to crack under heat during the operation of the heating component, making the lead wire 40 not easy to loosen and the connection not easy to leak air.

[0078] In addition to Kovar alloy wire and Invar alloy wire, lead 40 can also be silver wire, nickel wire, nickel-clad copper wire, stainless steel wire, or beryllium copper wire, and can be selected based on different design requirements, such as the strength and cost of lead 40.

[0079] Figure 3 This is a partial structural diagram of another heating component provided in an embodiment of this application, as shown below. Figure 3 As shown, the side wall of the medium container 10 has a through hole 10b, and a metal layer 12 is attached to the wall of the through hole 10b. The lead wire 40 is bonded to the metal layer 12.

[0080] By forming a metal layer 12 on the hole wall of the through hole 10b on the side wall of the medium container 10, and using the metal layer 12 to connect the lead wire 40 and the medium container 10, the risk of cracking at the connection between the lead wire 40 and the medium container 10 due to the difference in thermal expansion coefficients between the lead wire 40 and the medium container 10 can also be reduced.

[0081] For example, the metal layer 12 can be a silver layer or a copper layer. The medium container 10 can be a ceramic container.

[0082] In some examples, the heating element 30 is connected to at least one lead 40 at each end along the axial direction.

[0083] The heating element 30 is cylindrical. By connecting at least one lead wire 40 to each end, the two ends of the heating element 30 can be bound, making the heating element 30 more stable in the medium container 10 and preventing the ends of the heating element 30 from shaking in the medium container 10.

[0084] As an example, in Figure 2 In the example shown, the end of the heating element 30 near the support ring 20 can be connected to two leads 40, and the end of the heating element 30 away from the support ring 20 can be connected to one lead 40.

[0085] In other examples, the end of the heating element 30 away from the support ring 20 may also be connected to two leads 40, making the area at the connection between the leads 40 and the heating element 30 larger and reducing the risk of breakage at the connection.

[0086] The lead wire 40 and the heating element 30 can be welded, for example, by resistance welding, laser welding, arc welding, friction welding, electromagnetic welding, cold welding, electron beam welding, brazing, tin welding, spot welding and other methods.

[0087] Figure 4 This is a schematic diagram of the structure of a heating element provided in an embodiment of this application. Figure 4 The image also shows multiple leads 40 connected to the heating element 30. For example... Figure 4 As shown, the sidewall of the heating element 30 has two strip-shaped notches 30a. The two strip-shaped notches 30a are distributed at intervals along the circumference of the heating element 30, dividing the end of the heating element 30 near the socket 10a into a first semi-ring portion 32 and a second semi-ring portion 33. Each of the first semi-ring portion 32 and the second semi-ring portion 33 is connected to at least one lead wire 40.

[0088] In this example, the heating element 30 includes a cylindrical portion 31, a first semi-ring portion 32, and a second semi-ring portion 33. The first semi-ring portion 32 and the second semi-ring portion 33 are connected to the same end of the cylindrical portion 31, and the first semi-ring portion 32 and the second semi-ring portion 33 are arranged opposite to each other. Lead wires 40 are respectively connected to the end position of the first semi-ring portion 32 away from the cylindrical portion 31, the end position of the second semi-ring portion 33 away from the cylindrical portion 31, and the end position of the cylindrical portion 31 away from the first semi-ring portion 32 and the second semi-ring portion 33.

[0089] During heating, some or all of the cylindrical portion 31, the first semi-ring portion 32, and the second semi-ring portion 33 can be heated to achieve different heating effects.

[0090] For example, when the heating component first starts working, the medium can be preheated using the first semi-ring portion 32 and the second semi-ring portion 33. The preheating time can be 0 to 30 seconds, for example, 10 seconds or 15 seconds.

[0091] For example, the lead 40 connected to the first half-ring 32 can be connected to one pole of the power supply, and the lead 40 connected to the second half-ring 33 can be connected to the other pole of the power supply for power supply. The first half-ring 32 and the second half-ring 33 are connected in series, and the current flows through the first half-ring 32 and the second half-ring 33.

[0092] After preheating, the medium can be transitionally heated using one of the first semi-annular portion 32 and the second semi-annular portion 33, as well as the cylindrical portion 31. The transition heating time can be 0 to 50 seconds, for example, 10 seconds or 20 seconds.

[0093] For example, the lead 40 connected to the first half-ring portion 32 or the second half-ring portion 33 can be connected to one pole of the power supply, and the lead 40 connected to the cylindrical portion 31 can be connected to the other pole of the power supply for power supply. One of the first half-ring portion 32 and the second half-ring portion 33 is connected in series with the cylindrical portion 31, and the current flows through the first half-ring portion 32 or the second half-ring portion 33, as well as the cylindrical portion 31.

[0094] After the transition heating is completed, the medium can be continuously heated using the first semi-ring portion 32, the second semi-ring portion 33, and the cylindrical portion 31.

[0095] For example, the lead 40 connected to the first half-ring 32 and the lead 40 connected to the second half-ring 33 can be connected to the same pole of a power supply, and the lead 40 connected to the cylindrical part 31 can be connected to the other pole of the power supply for power supply. The first half-ring 32 and the second half-ring 33 are connected in parallel and in series with the cylindrical part 31. The current flowing through the cylindrical part 31 is the sum of the currents flowing through the first half-ring 32 and the second half-ring 33, which allows the cylindrical part 31 to be heated with a higher power than the first half-ring 32 and the second half-ring 33.

[0096] The three heating modes—preheating, transition heating, and continuous heating—can be freely combined according to specific needs. For example, after preheating, continuous heating can be initiated directly; after a period of continuous heating, a period of preheating or transition heating can be performed before returning to continuous heating. By combining different heating modes, different heating effects can be produced to meet the requirements of different users.

[0097] The power of the heating element 30 at different heating stages can be changed by altering the resistance of the first semi-ring portion 32, the second semi-ring portion 33, and the cylindrical portion 31. The heating element 30 is mesh-like, and the power of the heating element 30 can be changed by adjusting the size of the mesh, the line width of the heating element 30, and the thickness of the heating element 30, thereby changing the resistance of different parts of the heating element 30.

[0098] For example, during the preheating stage, the resistance of the first semi-ring portion 32 and the second semi-ring portion 33 connected in series can be 1Ω; during the transition heating stage, the resistance of one of the first semi-ring portion 32 and the second semi-ring portion 33 connected in series with the cylindrical portion 31 can be 0.7Ω; during the continuous heating stage, the resistance of the first semi-ring portion 32 and the second semi-ring portion 33 connected in parallel and connected in series with the cylindrical portion 31 can be 0.4Ω.

[0099] For example, the resistance of the first semi-ring portion 32 and the second semi-ring portion 33 can be equal, both being 0.5Ω, while the resistance of the cylindrical portion 31 can be 0.2Ω.

[0100] like Figure 4 As shown, the leads 40 connected to the first half-ring portion 32 and the leads 40 connected to the second half-ring portion 33 are symmetrically distributed.

[0101] Symmetrical distributions can include face-symmetric distributions and centrally symmetric distributions.

[0102] For example, the lead 40 connected to the first half-ring portion 32 and the lead 40 connected to the second half-ring portion 33 can be symmetrical, and the plane of symmetry can pass through the axis of the heating element 30; the lead 40 connected to the first half-ring portion 32 and the lead 40 connected to the second half-ring portion 33 can be centrally symmetrical about the axis of the heating element 30.

[0103] By arranging the leads 40 in a symmetrical manner, the forces exerted on the first half-ring 32 and the second half-ring 33 by the leads 40 can be more balanced, making the heating element 30 more stably suspended.

[0104] Figure 5 This is a partial structural diagram of a heating component provided in an embodiment of this application, as shown below. Figure 5 As shown, the heating assembly may also include an insulating support 50, which is inserted into the strip notch 30a and contacts the two sides of the strip notch 30a opposite to each other in the circumferential direction of the heating body 30.

[0105] Inserting a support member 50 into the strip-shaped notch 30a can provide support for the first half-ring portion 32 and the second half-ring portion 33, thereby improving the structural strength and stability of the heating element 30 and compensating for the impact of the strip-shaped notch 30a on the structural strength and stability.

[0106] For example, the support member 50 can be a ceramic part. Ceramic not only has a stable structure and high structural strength, but it is also insulating and can withstand high temperatures.

[0107] As an example, the support member 50 may be strip-shaped, and multiple first protrusions 51 may be distributed on both sides of the support member 50. The first protrusions 51 contact the sidewall of the strip-shaped notch 30a to support the first semi-ring portion 32 and the second semi-ring portion 33.

[0108] The support member 50 can be fixedly connected to the heating element 30, or it can be elastically engaged in the strip-shaped notch 30a between the first half-ring portion 32 and the second half-ring portion 33, or it can be connected to the inner wall of the medium container cylinder 10.

[0109] For example, the end of the first protrusion 51 may have a groove, and the side wall of the strip notch 30a may be engaged in the groove, so that the support 50 is installed more stably and the support 50 is prevented from becoming loose.

[0110] Figure 6 This is a partial structural diagram of a heating component provided in an embodiment of this application, as shown below. Figure 6 As shown, in some examples, the support member 50 can overlap with the first semi-ring portion 32 and the second semi-ring portion 33. The first semi-ring portion 32 and the second semi-ring portion 33 are respectively provided with connecting holes 30b, located on both sides of the strip-shaped notch 30a. The surface of the support member 50 is provided with a plurality of second protrusions 52, located in the overlapping areas of the support member 50 and the first semi-ring portion 32, and in the overlapping areas of the support member 50 and the second semi-ring portion 33. The second protrusions 52 are inserted into the connecting holes 30b.

[0111] The second protrusion 52, in conjunction with the connecting hole 30b, can stably connect the first half-ring portion 32 and the second half-ring portion 33, and provide support to prevent deformation of the first half-ring portion 32 and the second half-ring portion 33.

[0112] The heating element 30 is mesh-like. In some examples, the second protrusion 52 may also be located in the mesh of the heating element 30. The second protrusion 52 may fit against the sidewall of the mesh near the strip notch 30a to avoid deformation of the first semi-ring portion 32 and the second semi-ring portion 33 in a direction away from each other.

[0113] In some examples, the inner wall of the heating element 30 may be provided with an infrared coating.

[0114] Applying an infrared coating to the inner wall of the heating element 30 can improve the heat radiation capability of the heating element 30, thereby improving the heating efficiency of the heating element 30.

[0115] For example, the infrared coating can be a chromium oxide coating, a silicon carbide coating, a chromium nitride coating, or a spinel oxide coating.

[0116] The heating element 30 can also be nitrided to form nitrides on its inner wall, thereby improving its thermal radiation capacity.

[0117] This application also provides an atomizing device, which includes a power supply and any of the aforementioned heating components. The power supply can be connected to the lead 40 and is used to supply power to the heating component.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
