The existing heating does not burn electronic smoking set, heat conduction part in the air heating assembly sets up as a whole, is provided with the air current passageway on heat conduction part, and the heating part sets up on heat conduction part's outer wall, and the heat that the heating part produced will pass to heat conduction part when the heating part circular telegram generates heat to realize heating the air through the air current passageway. However, since the heat generating component is disposed on the outer wall of the heat conducting component, the heat generated by the heat generating component can be only unidirectionally conducted to the heat conducting component, so that the air heating assembly cannot quickly heat the room-temperature air to the required air temperature, and the efficiency of heating the air by the heat conducting component is low. Accordingly, a first embodiment of the present application provides an air heating assembly and an electronic smoking article for heating a smoking article, wherein the smoking article may be a cigarette or a product capable of generating volatile substances after heating. Referring to fig. 1, the air heating assembly includes a heat generating part 100 and two heat conductive parts 200.

Specifically, the two heat conducting members 200 are disposed on opposite sides of the heat generating member 100, and the two heat conducting members 200 are stacked with the heat generating member 100, and the two heat conducting members 200 are each provided with a first air flow channel 210, and the first air flow channels 210 of the two heat conducting members 200 are communicated.

By disposing the two heat conductive members 200 on opposite sides of the heat generating member 100, and disposing the heat conductive members 200 in a stacked arrangement with the heat generating member 100, while providing the first air flow channels 210 in both of the two heat conductive members 200, and disposing the first air flow channels 210 of both of the heat conductive members 200 in communication; when the heat generating part 100 generates heat, the heat generating part 100 can simultaneously conduct heat toward the heat conducting parts 200 located at both sides, thereby improving efficiency of the air heating assembly in heating air.

In the present embodiment, in order to reduce the cost, the heat generating component 100 is provided as a resistance wire. The heat conductive member 200 is heated by the heating wire, and the heat conductive member 200 performs a heat convection with the air in the first air flow channel 210. In this embodiment, the heating wire is at least one of stainless steel, nichrome, nickel-iron alloy, iron-chromium-aluminum alloy.

In the present embodiment, since the heat conducting member 200 mainly functions to conduct heat generated by the heat generating member 100 to the heat conducting member 200 itself, and then transfer the heat to the air flow flowing through the heat conducting member 200 by means of convection heat exchange, the air at room temperature is heated to a desired temperature. Therefore, the thermal conductivity of the thermal conductive member 200 is set to be larger than 15W/mK, so that the thermal conductive member 200 can conduct heat efficiently. In this embodiment, the heat conductive member 200 is a metal material such as stainless steel or aluminum alloy; in other embodiments, the heat conductive member 200 may be aluminum nitride ceramic.

In the present embodiment, the heat generating component 100 and the heat conducting component 200 are connected and mounted by means of gluing or strong press fit.

Process of assembling an air heating assembly: since the air heating assembly at this time includes: the heat conductive member 200, the heat generating member 100, and the heat conductive member 200 are stacked in this order. Therefore, when in installation, one of the heat conducting members 200 is positioned, then the bonding glue is coated on two opposite sides of the heat generating member 100, then the heat generating member 100 is placed on the positioned heat conducting member 200, the heat generating member 100 is ensured to be dislocated with the first air flow channel 210 on the positioned heat conducting member 200, and finally the other heat conducting member 200 is placed on the heat conducting member 200, so that the air flow channel on the heat conducting member 200 installed later corresponds to the first air flow channel 210 on the heat conducting member 200 positioned earlier, and the installation of the air heating assembly can be completed.

In operation, the heat conductive member 200 is heated by the heating member, and air passes through the heat conductive member 200 from the first air flow path 210, and the air is preheated to a preset temperature by the heat conductive member 200.

In this embodiment, since the first airflow channel 210 is disposed on the heat conducting member 200, the first airflow channel 210 can make the air exchange heat with the heat conducting member 200, and if the air directly contacts the heat generating member 100 when passing through the first airflow channel 210, the heat generating member 100 directly heats the air, which may result in uneven temperature when the air heating assembly heats. Therefore, the first airflow channel 210 includes a plurality of first through holes 211 arranged in an array on the heat conducting member 200, the first through holes 211 penetrate from the first surface to the second surface of the heat conducting member 200, a preset interval is provided between two adjacent first through holes 211 on the heat conducting member 200, the heat generating member 100 includes a bending portion 110, the bending portion 110 is located between two adjacent first through holes 211, and the first surface and the second surface of the heat conducting member 200 are opposite. Because the heating component 100 comprises the bending part 110, the bending part 110 is positioned between two adjacent first through holes 211, so that air is not in direct contact with the heating component 100, and the air heating component can more accurately control the temperature of air heating; meanwhile, when the air heating assembly heats air, heat generated by the heat generating component 100 needs to be conducted to the heat conducting component 200 at first, and then air passing through the first air flow channel 210 is heated by the heat conducting component 200, so that the heat generated by the heat generating component 100 can be more uniformly distributed on the heat conducting component 200; and because a plurality of first through holes 211 are arranged on the heat conducting component in an array manner, the side walls of the first through holes 211 at different positions on the heat conducting component 200 can perform heat convection, so that the contact area between air and the heat conducting component 200 is increased, and the efficiency of the air heating component in heating air is improved.

Further, the heat generating component 100 further includes a straight portion 120, and the straight portion 120 is located at both ends of the curved portion 110.

The bending portion 120 is provided to include a plurality of horizontal segments 111 and a plurality of vertical segments 112; so that the heat generating part 100 and the heat conductive part 200 can have a larger contact area, thereby further improving the efficiency of the air heating assembly when heating air; meanwhile, the ends of the plurality of vertical sections 112 are sequentially connected with the ends of the plurality of horizontal sections 111, and the plurality of horizontal sections 111 and the plurality of vertical sections 112 are arranged at intervals, so that the heating component 100 can be more uniformly distributed in different areas of the heat conducting component 200, and the heat in a certain area on the heat conducting component 200 is prevented from being excessively concentrated. In other embodiments, the shape of the curved portion 110 may be consistent with a sine function or cosine function curve.
