Therefore, the higher the insulation efficiency of the heating element, the lower the energy required to heat the same volume of material.

Alternatively, a heating film is added to the outer surface of the insulation within the heating element to improve insulation efficiency.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0043] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] To solve the above problems, please refer to Figures 1 to 4 The embodiment of the present application provides a heating assembly 100, which includes:

[0045] A heating body 110 , the heating body 110 is used to generate heat to heat a material to be heated (not shown in the figure);

[0046] at least one supporting portion 120 , the supporting portion 120 being located on a side wall of the heating body 110 and protruding in a direction away from the heating body 110 ;

[0047] The heat insulating member 200 has a receiving cavity (not marked in the figure) disposed therein;

[0048] The heating body 110 and the support portion 120 are both located in the accommodating cavity, and the heat insulating member 200 and the heating body 110 together define a heat insulating cavity 140 .

[0049] The effect of this embodiment is: because the support portion 120 is located on the side wall of the heating body 110 and protrudes in the direction away from the heating body 110, the two ends of the support portion 120 and the heating body 110 are arched to form a dumbbell-shaped structure. At this time, when the heating body 110 is located in the accommodating cavity, the side of the support portion 120 away from the heating body 110 will be against the inner wall of the thermal insulation member 200, thereby forming an insulating cavity 140 between the inner wall of the heating body 110 and the thermal insulation member 200 and the side wall of the support portion 120. The insulating cavity 140 can be a vacuum environment or filled with inert gas or air. Air, inert gas, and vacuum are all poor conductors of heat. Therefore, when the heating body 110 is in a heating state, its heat conduction effect can be blocked by the insulating cavity 140, thereby preventing its heat dissipation.

[0050] In summary, this embodiment improves the thermal insulation efficiency of the heating component 100 without adding any additional components such as a heating film, thereby reducing the production cost of the heating component.

[0051] It is understood that the support portion 120 and the heating body 110 may be integrally formed or detachably connected. The support portion 120 may be only on one side of the heating body 110, or may be Figure 2 、 Figure 3 The heating element 110 is shown on both sides of the heating element 110. The heating element 110 is typically provided with an airflow channel (not shown) for gas circulation. Therefore, to prevent corrosion of the heating element 110 by external oxygen, an anti-oxidation protective coating may be provided on the inner wall of the heating element 110. To further improve the heating efficiency of the material to be heated, a high infrared emissivity coating or a high thermal conductivity coating may be provided on the inner wall of the heating element 110, thereby improving the heating efficiency of the material to be heated.

[0052] For further information, please refer to Figure 2 The heating assembly 100 further includes an insulating member 300 , which is sleeved on the supporting portion 120 , and an outer wall of the insulating member 300 abuts against an inner wall of the thermal insulation member 200 .

[0053] The effect of this embodiment is that the insulating member 300 can separate the support portion 120 and the thermal insulation member 200, thereby preventing direct electrical connection between the thermal insulation member 200 and the heating body 110. This prevents problems such as short circuits caused by direct contact between the heating body 110 and the thermal insulation member 200. Furthermore, the insulating member 300 can provide a certain degree of thermal insulation, further improving the thermal insulation efficiency of the heating assembly 100.

[0054] It is understood that the insulating member 300 may be an annular structure and may be interference fit between the insulating member 300 and the thermal insulation member 200 and / or the heating body 110, thereby improving the strength after assembly.

[0055] For further information, please refer to Figures 1 to 4 , the thickness of the insulating member 300 is 0.05 mm to 0.5 mm; and / or,

[0056] The thermal conductivity of the insulating member 300 is ≤ 0.3 W / (m·K); and / or,

[0057] The thermal expansion coefficient of the insulating member 300 is ≤ 5 (ppm / °C); and / or,

[0058] The thickness of the thermal insulation member 200 is 0.5 mm to 2 mm; and / or,

[0059] The vacuum degree in the insulation cavity 140 is less than 50 Pa; and / or,

[0060] The length of the heat insulating member 200 is consistent with the length of the heating body 110 .

[0061] The effect of this embodiment is that the thickness of the insulating member 300 affects the size of the heating assembly 100, and further affects the size and cost of the heating assembly 100. To keep the size and cost within a predetermined range, the thickness of the insulating member 300 of this application is 0.05 mm to 0.5 mm.

[0062] The thermal conductivity of the insulating member 300 will affect the thermal insulation efficiency of the heating assembly 100 . To further prevent heat loss during heating of the heating body 110 , the thermal conductivity of the insulating member 300 is ≤0.3 W / (m·K).

[0063] The thermal expansion coefficient of the insulating member 300 will affect the volume of the heating body 110 when the insulating member 300 is working. To prevent the insulating member 300 from colliding during work and causing deformation of the heat insulating member 200 or the heating body 110, its thermal expansion coefficient can be ≤5 (ppm / °C).

[0064] The thickness of the insulating member 300 will also affect the size of the heating assembly 100, and further affect the size and cost of the heating assembly 100. To keep the size and cost within a predetermined range, the thickness of the insulating member 200 of the present application is 0.5 mm to 2 mm.

[0065] The vacuum degree refers to the degree of gas rarefaction in the insulation cavity 140. The smaller the value, the less gas components in the insulation cavity 140, the less medium inside the insulation cavity 140 that can provide heat transfer, and the better the insulation effect of the insulation cavity 140. Therefore, the vacuum degree of this embodiment is <50Pa.

[0066] It can be understood that the material of the insulating part 300 can be at least one of aerogel coating, silicate inorganic glue, and phosphate inorganic glue, and its formation method can be one or more of dipping, plasma spraying, flame spraying, arc spraying or supersonic flame spraying. When it is formed, the curing temperature can be 200~800℃, and the coating hardness can be 5H~9H.

[0067] For further information, please refer to Figures 1 to 4 , the protrusion height of the support portion 120 is 0.3mm to 3mm; and / or,

[0068] The length of the support portion 120 is 2 mm to 5 mm; and / or,

[0069] A slope is provided at the connection between the support portion 120 and the heating body 110; and / or,

[0070] The inner diameter of the heating body 110 is 6 mm to 9 mm; and / or,

[0071] The length of the heating body 110 is 5 mm to 44 mm; and / or.

[0072] The height direction of the protrusion of the support portion 120 is Figure 3 The Y direction in the Figure 3 The Z direction in .

[0073] The effects of this embodiment are:

[0074] The raised height and length of the support portion 120, and the inner diameter and length of the heating body 110, all affect the size of the heating assembly 100, and thus the size and cost of the heating assembly 100. Therefore, the ranges of the raised height and length of the support portion 120, and the inner diameter and length of the heating body 110 in this embodiment ensure that the production cost of the heating assembly 100 is low, and the practicality and structural strength meet expectations. Providing inclined surfaces on the support portion 120 and the heating body 110 can improve the structural strength of the support portion 120.

[0075] It can be understood that after testing, the inner diameter and length of the heating body 110 have the smallest size and cost of the heating component 100 under two combinations, namely: the inner diameter of the heating component 100 is 6mm~7mm, and the length range is 30mm~46mm; and the inner diameter of the heating component 100 is 7~9mm, and the length range is 10~24mm.

[0076] For further information, please refer to Figures 1 to 3 , there are two support parts 120, and the two support parts 120 are symmetrically distributed at both ends of the heating body 110; and / or,

[0077] The heating body 110 is tubular, and an air flow channel is provided inside the heating body 110 for allowing gas to flow.

[0078] The effect of this embodiment is that when there are two support parts 120, which are symmetrically distributed at both ends of the heating body 110, after the heating body 110 and the insulation tube are assembled, the force is evenly distributed at all parts, the structural strength is high, and the service life of the heating component 100 can be effectively improved. Figure 2 、 Figure 3 The heating body 110 is shown on both sides thereof. The heating body 110 is usually provided with an air flow channel for gas circulation.

[0079] For further information, please refer to Figures 2 to 4 The heating body 110 includes a plurality of heating parts 130 connected end to end and at least partially spaced apart;

[0080] The heat generating portion 130 is used to guide current to flow along a preset path formed by the plurality of heat generating portions 130 .

[0081] The effect of this embodiment is that since the heating parts 130 are at least partially separated and the heating parts 130 are connected end to end, the heating parts 130 can guide the current to flow along the heating parts 130 in a serpentine manner according to the preset path, that is, the current can be Figure 4 As shown by the middle arrow, the heat is spread over the entire inner wall of the heating body 110 , thereby achieving a uniform heating effect on the material to be heated in the accommodating cavity.

[0082] For further information, please refer to Figures 1 to 3 The heating body 110 has a first opening (not marked in the figure) for allowing the material to be heated to enter and a second opening (not marked in the figure) located at the opposite end of the first opening. A gap is formed between two adjacent heating parts 130, one end of the gap passes through the first opening or the second opening, and the other end of the gap extends to near the second opening or the first opening.

[0083] The effect of this embodiment is that the gap includes a first gap 111, a second gap 112 and a third gap. The first gap 111 connects the upper edge (the side where the lead 400 is provided in the figure) and the lower edge (the side where the lead 400 is not provided in the figure) of the side wall of the heating body 110. The second gap 112 (not shown in the figure) extends from the upper edge of the side wall of the heating body 110 to the lower edge, but there is a gap between it and the lower edge, that is, it is not connected to the lower edge. The third gap extends from the lower edge of the side wall to the upper edge, but there is a gap between it and the upper edge, that is, it is not connected to the upper edge. The second gap 112 and the third gap are distributed at intervals. At this time, because the gap will have a blocking effect on the current, the inner wall of the heating body 110 is restricted by the gap to form a current conduction channel, that is, the current will flow along the heating part 130, serpentinely connected and spread throughout the inner wall of the entire heating body 110, thereby achieving the effect of uniformly heating the smokeable material located in the accommodating cavity.

[0084] It is understood that the shape, size, and distribution of the gaps can be adjusted according to actual needs, as long as the gaps enable the inner wall of the heating body 110 to form a heat-generating portion 130 that is connected end to end and at least partially separated. For example, a spiral-shaped gap can be designed in the sidewall, extending from the bottom of the inner wall of the heating body 110 to the top of the sidewall, thereby defining a spirally ascending current conduction channel. In this case, current can still flow throughout the inner wall of the heating body 110, achieving uniform heating. If a single current conduction channel is used, the heating rate of the heating assembly 100 may be slow, meaning that the current requires time to flow through the entire current conduction channel. Therefore, the gaps can also form multiple current conduction channels on the sidewall of the heating body 110. In this case, by providing multiple leads 400, current can flow through each current conduction channel, thereby shortening the current flow distance and improving the heating efficiency of the heating assembly 100. The materials of the heating body 110 include, but are not limited to, nickel-chromium alloy, iron-chromium-aluminum alloy, stainless steel alloy, palladium-gold, graphene, or a combination thereof.

[0085] For further information, please refer to Figures 1 to 4 , the heating assembly 100 further includes at least two leads 400;

[0086] At least one lead wire 400 is connected to a starting end of the heating portion 130 , and at least another lead wire 400 is connected to a terminal end of the heating portion 130 .

[0087] The effect of this embodiment is that when there is only one current conduction path, the distance that the current can flow varies depending on the position of the two leads 400, that is, the area that the heating element 100 can heat varies. In this embodiment of the application, the two leads 400 are located at the starting and ending points of the heating portion 130, respectively, allowing the current to flow completely through the entire inner wall of the heating element 100, further improving the uniform heating effect of the heating element 100.

[0088] For further information, please refer to Figures 2 to 4 , the width of the gap is less than 0.5 mm; and / or,

[0089] The heating assembly 100 further includes an insulating filler (not shown in the figures), which is filled in the gap to enhance the strength of the heating body 110 .

[0090] The effect of this embodiment is that if the gap width is too large, the strength of the heating body 110 will be low. Therefore, the gap width of this embodiment can prevent the structural strength of the heating body 110 from being too low when the gap is sufficient to isolate the flow of current.

[0091] Correspondingly, the present application also provides an atomization device, which includes the heating assembly 100 of any one of the above embodiments.

[0092] The effect of this embodiment is that since the atomizing device includes the heating assembly 100 in the above embodiment, the atomizing device has high heat insulation efficiency and low production cost.

[0093] It is understandable that the atomization device in the above embodiments includes but is not limited to aerosol generating devices, aromatherapy machines, drug atomizers, fire sprinkler systems, cleaning equipment, irrigation equipment, beauty equipment, laboratory solute extraction equipment and other equipment.
