Description

Technical Field

[0001] This invention relates to the field of aerosol generation device technology, and more particularly to a heating component and atomizing device. Background Technology

[0002] Traditional cigarettes produce a large amount of harmful substances during combustion, leading some to use heated tobacco products (HTMs) as an alternative. HTMs involve inserting a cartridge (atomized substance) into the device, which is then heated at a low temperature for inhalation. Specifically, the cartridge is inserted into a heating pin inside the device. The heating pin heats the cartridge at a low temperature for easy inhalation. However, because the side of the heating pin is continuously flat, a significant amount of cartridge residue remains on the side after heating. When the cartridge is heated again, this residue prevents the heating pin from fully heating it, affecting the flavor. Summary of the Invention

[0003] Therefore, it is necessary to provide a heating component and atomizing device to address the problem that a large amount of e-liquid residue remains on the side of the heating needle after heating is complete.

[0004] This invention provides a heating assembly, comprising:

[0005] A heating element includes opposing first and second ends and a heating portion located between the first and second ends, wherein the outer peripheral surface of the heating portion is a discontinuous surface.

[0006] A conductive component, one end of which is connected to the heating element, and the other end of which is connected to a power source to supply power to the heating element for heating.

[0007] The aforementioned heating component can be installed in an atomizing device, which can then heat the atomized material for the user to inhale. Specifically, when energized, the conductive component drives the heating component to heat up, thereby heating and atomizing the atomized material in contact with the heating component to form an aerosol, which can then be inhaled by the user. The heating component heats the atomized material by contacting its heating part. This heating part is a discontinuous planar shape, ensuring that no residue remains after heating the atomized material, thus not affecting the subsequent heating of new atomized material.

[0008] In one embodiment, the heating element includes a plurality of heating units arranged in a stacked manner, with two adjacent heating units electrically connected, and the sides of the plurality of heating units forming a discontinuous planar heating portion.

[0009] In one embodiment, the heating element further includes a guide unit, one end of which is connected to the outermost heating unit, and the other end of which is tapered.

[0010] In one embodiment, the heating element includes a spiral conductor, which is a spiral strip and has spiral grooves, so that the outer peripheral side of the spiral conductor forms a discontinuous surface of the heating element.

[0011] In one embodiment, the heating unit is a closed annular sheet, and the heating element further includes a support and a conductive material. The support is located between two adjacent heating units, and the conductive material is electrically connected to the two adjacent heating units.

[0012] In one embodiment, the support portion includes at least one of a first support ring, a second support ring, and a third support ring. The first support ring has a first through hole along the axial direction, the second support ring has a notch along the radial direction, and the third support ring has a plurality of second through holes along the axial direction. The first through hole, the second through hole, or the notch can all be filled with the conductive material so that the conductive material electrically connects two adjacent heating units.

[0013] In one embodiment, the support includes an insulating ring with an outer diameter smaller than that of the heating unit. The insulating ring and the conductive material are both disposed between two adjacent heating units, with the conductive material located outside the insulating ring.

[0014] In one embodiment, the heating assembly further includes a support rod and a filler. The support rod is not in contact with the heating element and is fixed relative to it by the filler. One end of the support rod passes through the heating element and is electrically connected to the conductive element, and the other end of the support rod is tapered.

[0015] In one embodiment, the heating assembly further includes an insulating base, and the heating element, the support rod, and the conductive element are all connected to the insulating base and fixed relative to each other.

[0016] The present invention also provides an atomizing device, including a battery, a storage cavity and the above-mentioned heating component. The storage cavity is used to store atomized material, and the battery is electrically connected to the conductive element to supply power to the heating element through the conductive element, thereby heating the atomized material by the heating part of the heating element.

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the specific details described below are only a part of the embodiments of the present invention, and the present invention can be implemented in many other embodiments different from those described herein. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] Please refer to Figure 1 The present invention provides an atomizing device 100 for heating atomized material (cigarette cartridge) at low temperature to generate an aerosol for inhalation by a user.

[0037] The atomizing device 100 includes a housing 101, a battery 102, and a heating assembly 103. The housing 101 contains an atomizing chamber 1011 and a storage chamber 1012, with the battery 102 located in the storage chamber 1012. The atomizing chamber 1011 houses the heating assembly 103, and the battery 102 is electrically connected to the heating assembly 103 to supply power. When the heating assembly 103 is energized, it generates heat, thereby heating the atomized material inserted into the atomizing chamber 101 at a low temperature, causing the atomized material to generate an aerosol.

[0038] The heating assembly 103 includes a heating element 1, a support rod 2, a conductive element 3, and an insulating base 4. The heating element 1, support rod 2, and conductive element 3 are all connected to the insulating base 4 and kept relatively fixed. At the same time, the conductive element 3 is electrically connected to both the heating element 1 and the support rod 2.

[0039] The conductive component 3 includes a first lead 31 and a second lead 32. One end of the first lead 31 is connected to the heating element 1, and one end of the second lead 32 is connected to the support rod 2. The other ends of both the first lead 31 and the second lead 32 are electrically connected to the battery 102, so that the battery 102 can supply power to the heating element 1 through the first lead 31, enabling the heating element 1 to generate heat and thus heat the atomized material. It should be emphasized that the heating element 1 does not contact the support rod 2 to avoid short circuits.

[0040] The support rod 2 is made of a conductive material, such as copper or aluminum.

[0041] refer to Figure 2 and Figure 3 The support rod 2 includes a rod body 21 and a guide body 22. One end of the rod body 21 is connected to the insulating base 4, and the other end of the rod body 21 is connected to the guide body 22. The end of the guide body 22 facing away from the rod body 21 is tapered. The heating element 1 is sleeved on the rod body 21, and in the length extension direction of the support rod 2, the heating element 1 is located between the insulating base 4 and the guide body 22. The guide body 22 can play a guiding role, and the end of the atomized material can press against the guide body 22 so that the side wall of the heating element 1 can contact the atomized material, thereby heating the atomized material.

[0042] The heating element 1 includes multiple heating units 11 arranged in a stacked manner, with adjacent heating units 11 electrically connected. The sides of the multiple heating units 11 form a discontinuous (uneven) heating portion 14. Alternatively, the heating element 1 can be understood as including opposing first end 12 and second end 13, with the heating portion 14 located between the first end 12 and the second end 13. Furthermore, the first end 12 is electrically connected to a first lead 31. When the heating portion 14 contacts and heats the atomized material, the residue after combustion is less likely to remain on the uneven heating portion 14, reducing the adhesion of residue to the heating portion 14. When new atomized material contacts the heating portion 14, the heating portion 14 can fully heat the atomized material, resulting in a good-tasting aerosol.

[0043] Figure 2 and Figure 3The heating unit 11 in the illustrated embodiment is a non-closed spiral, and adjacent heating units 11 are spirally connected, forming a complete spiral body, similar to the shape of a spring. Alternatively, the heating part 14 can be understood as including a spiral conductor, which is a long spiral strip with spiral grooves, so that the outer peripheral surface of the spiral conductor forms a discontinuous planar heating part. There is a gap between adjacent heating units 11, allowing the heating range of the heating part 14 to be larger, enabling efficient heating of the atomized material. Of course, in other embodiments, there may be no gap between adjacent heating units 11, meaning that adjacent heating units 11 are directly connected vertically. Both methods result in a discontinuous planar heating part 14, ensuring that after heating the atomized material, residue from the atomized material does not easily adhere to the heating part 14.

[0044] It is important to emphasize that the outer peripheral surface of the heating part 14 is a discontinuous surface, which mainly includes the following situations: (1) The outer peripheral surface of the heating part 14 has gaps, the shape and area of ​​which are not limited, so that the outer peripheral surface of the heating part 14 cannot form a continuous surface; (2) The outer peripheral surface of the heating part 14 has no gaps, but the outer peripheral surface of the heating part 14 is uneven.

[0045] Figure 2 and Figure 3 The embodiments shown all include a guide body 22 for the support rod 2 and a cone-shaped guide body 22 for pressing the atomized material, so that the interior of the atomized material can be quickly inserted into the heating element 1 until the interior of the atomized material is in full contact with the heating element 14. The heating element 1 is spirally arranged around the rod body 21 of the support rod 2. The first end 12 of the heating element 1 is connected to the first lead wire 31, and the second end 13 of the heating element 1 is connected to the guide body 22 of the support rod 2 through a spiral ring 23. It should be emphasized that the spiral ring 23 is made of an insulating material, such as a high-temperature resistant plastic, to avoid short circuits caused by electrical connection between the heating element 1 and the support rod 2. In addition, there is also a gap between the heating element 1 and the rod body 21. In order to improve the stability of the relative fixation between the heating element 1 and the support rod 2, an insulating material, such as a high-temperature resistant colloid, can be filled between the rod body 21 and the heating element 1, which can improve the rigidity of the heating element 1 and the support rod 2 and prevent deformation during use.

[0046] Figure 4 and Figure 5 The support rods 2 in the illustrated embodiments do not have guide bodies 22, but only rod bodies 21. The rod bodies 21 are located entirely inside the heating element 1.

[0047] The heating element 1 also includes a guide unit 15, one end of which is connected to the outermost heating unit 11, and the other end of which is tapered. The function of the guide unit 15 is similar to... Figure 1The guide body 22 in the illustrated embodiments is consistent, all designed to facilitate rapid movement of the atomized material to the heating element 14, allowing the heating element 14 to heat the atomized material. It should be emphasized that... Figure 4 and Figure 5 In the illustrated embodiment, the guide unit 15 is an insulator, and the rod 21 is directly connected to the guide unit 15 inside the heating element 1. During operation, the guide unit 15 does not generate heat and only serves to facilitate the quick insertion of the atomized material.

[0048] It is understood that in other embodiments, the guide unit 15 may also use the same material as the heating element 1 or be integrally formed with the heating element 1. In this embodiment, the guide unit 15 not only provides a quick connection with the atomized material, but also generates heat during operation, thereby improving the heating efficiency of the atomized material. It should be emphasized that in this embodiment, an insulator needs to be provided between the rod 21 and the guide unit 15 to prevent the rod 21 from directly contacting the guide unit 15 and causing a short circuit.

[0049] Figures 2 to 5 In the embodiments shown, the insulating base 4 is not provided, and the heating element 1 can be installed in the atomizing chamber 1011 in other ways. In other embodiments, Figures 2 to 5 The embodiment shown can also be equipped with an insulating base 4, and the atomizing unit 11, rod 21, first lead 31 and second lead 32 are all fixed relative to each other by the insulating base 4, which can improve the stability of the heating component 103.

[0050] refer to Figure 6 and Figure 7 , Figure 6 and Figure 7 The heating unit 11 in the illustrated embodiment is a closed sheet-like heating ring 16. The heating element 1 also includes a support portion 17 and a conductive material 18. There are multiple heating rings 16, which are stacked one on top of the other. Adjacent heating rings 16 are separated by the support portion 17 and electrically connected by the conductive material 18.

[0051] The support portion 17 includes at least one of a first support ring 171, a second support ring 172, and a third support ring 173. The diameters of the heating ring 16, the first support ring 171, the second support ring 172, and the third support ring 173 are basically the same, so that after the multiple heating rings 16 and the support rings are stacked and installed, the heating portion 14 formed by the multiple heating rings 16 and the outer wall of the support ring is a discontinuous surface. After the heating rings 16 heat the atomized material, the residue of the atomized material combustion is not easily attached to the heating portion 14.

[0052] The first support ring 171 has a first through hole 1711 extending through it along its thickness direction (axial direction), the second support ring 172 has a notch 1721 extending through it along its diameter direction (radial direction), and the third support ring 173 has multiple second through holes 1731 extending through it along its thickness direction (axial direction). The first through hole 1711, the second through hole 1731 and the notch 1721 can all be filled with conductive material 18 so that the conductive material 18 can simultaneously contact the two adjacent heating rings 16 and electrically connect the two adjacent heating rings 16.

[0053] Figure 6 and Figure 7 The support portion 17 in the illustrated embodiment includes only a first support ring 171. There are multiple first support rings 171 and multiple heating rings 16, with the heating rings 16 and the first support rings 171 arranged in a staggered, overlapping manner. It should be emphasized that the first through holes 1711 of two adjacent first support rings 171 are not located on the same straight line, but are staggered, ensuring stable installation of the multiple first support rings 171.

[0054] The first support ring 171, the second support ring 172, and the third support ring 173 can all be made of insulating material. During installation, the inner walls of the first support ring 171, the second support ring 172, and the third support ring 173 can abut against the rod body 21 of the support rod 2 to enhance the overall stability of the heating assembly and prevent short circuits.

[0055] The aforementioned conductive material 18 is made of conductive material, such as solder. During the assembly process, the heating rings 16 and the first support rings 171 can be alternately fitted onto the rod body 21 one by one, and solder can be injected through the first through hole 1711 of the first support ring 171 to connect the multiple heating rings 16.

[0056] Figure 6 and Figure 7 The illustrated embodiment also includes an insulating base 4. One end of the first lead 31 passes through the insulating base 4 and is electrically connected to the bottommost heating ring 16. The other end of the first lead 31 is electrically connected to the negative terminal of the battery. The end of the rod 21 away from the guide 22 passes through the insulating base 4 and is electrically connected to one end of the second lead 32. The other end of the second lead 32 is electrically connected to the positive terminal of the battery. Powered by the battery, multiple heating rings 16 can heat up simultaneously to heat and atomize the atomized material in contact with them.

[0057] refer to Figure 8 , Figure 9 and Figure 10 , Figure 8 and Figure 9 The illustrated embodiments and Figure 6 and Figure 7 The only difference is the structure of the support part 17; the other structures are basically the same.

[0058] Figure 8 and Figure 9 The support portion 17 of the illustrated embodiment includes a plurality of insulating rings 174, each insulating ring 174 being located between two adjacent heating rings 16, serving to support and fix the heating rings 16. It should be emphasized that the inner diameter of the insulating ring 174 is equal to the inner diameter of the heating ring 16, while the outer diameter of the insulating ring 174 is smaller than the outer diameter of the heating ring 16. The area of ​​the heating ring 16 that is larger than the insulating ring 174 is used to install a conductive material 18; that is, the conductive material 18 is also located between two adjacent heating rings 16, for electrically connecting the two adjacent heating rings 16.

[0059] and Figure 6 and Figure 7 Compared to the illustrated embodiment, the main difference is that the conductive element 18 in this embodiment has fewer installation limitations and can be installed in any area outside the insulating ring 174 and inside the heating ring 16. Figure 6 and Figure 7 The conductive material 18 in the illustrated embodiment can only be installed in the hole corresponding to the support ring, making the installation process more convenient. The conductive material 18 in this embodiment can be a silver-based or copper-based solder or other conductive material with good temperature resistance.

[0060] Since the outer diameter of the insulating ring 174 is smaller than the outer diameter of the heating ring 16, the outer surface of the insulating ring 174 cannot be flush with the outer surface of the heating ring 16, resulting in larger pores in the heating part 14. After the heating part 14 heats the atomized material, the residue of the atomized material is less likely to adhere to the heating part 14.

[0061] It is understandable that if it is necessary to further enlarge the aperture of the heating element 14, the number of insulating rings 174 can be increased between two adjacent heating rings 16.

[0062] It should be emphasized that there is a gap between two adjacent heating rings 16 in this embodiment. During the heating process, the heating ring 16 can heat the air in the gap, and the hot air in the gap can heat the atomized material. Because the gap is evenly distributed, the atomized material can be heated evenly, resulting in a good taste of the aerosol produced by the atomized material.

[0063] To further increase the insulation between the heating element 1 and the support rod 2, an insulating film can be coated on the surface of the support rod 2. This insulating film can be a ceramic glaze, glass glaze, or inorganic adhesive film, etc. Alternatively, an insulating spacer can be added between the heating element 1 and the support rod 2. This insulating spacer can be anodized aluminum, ceramic, glass, etc. Or, the support rod 2 can be anodized in situ. For example, if the support rod 2 is made of aluminum and placed in air, its outer surface will oxidize to aluminum oxide. Aluminum oxide reduces the conductivity between the support rod 2 and the heating element 1.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications, substitutions, and improvements without departing from the concept of the present invention, and these should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of this invention should be determined by the claims.
