[0028] In one embodiment, a heating assembly of an atomization device is provided, which is a heating non-combustion device for inserting a smoking article or the like atomization substrate for heating and atomization smoking use. The heating assembly redesigns the outer shape structure of the heating body, sets the heating body into a tapered structure, and the upper end of the heating body is smaller than the lower end during use, so that the tobacco residue generated by heating the atomization substrate will slide down to the bottom under the action of gravity, without being bonded to the heating body, and the heating body is not easy to get dirty, reducing the cleaning difficulty of the heating body.

[0029] Please refer to Figure 1 and Figure 2 The heating assembly of the embodiment mainly includes a heating body 1 and a mounting seat 2. The heating body 1 is a long rod structure, one end of the heating body 1 is used for inserting into the atomization substrate, and the other end of the heating body 1 is connected with the mounting seat 2. The mounting seat 2 is used for fixing and mounting the heating body 1 in the atomization device, and the end of the heating body 1 away from the mounting seat 2 is inserted into the heating cavity of the atomization device, so that the end of the heating body 1 away from the mounting seat 2 can be inserted into the atomization substrate to heat the atomization substrate internally, realizing heating and roasting smoking.

[0030] The heating body 1 includes an insertion part 11 and a mounting part 12, which are connected side by side along the axial length direction of the heating body 1. The insertion part 11 and the mounting part 12 can be an integrated structure, and the insertion part 11 can be fixedly connected with the mounting part 12 by welding, clamping, bonding or the like.

[0031] The insertion part 11 includes opposite first and second ends. The first end of the insertion part 11 is away from the mounting part 12, and the second end of the insertion part 11 is connected with the mounting part 12. The insertion part 11 is used for inserting into the atomization substrate to heat the atomization substrate. The mounting part 12 is connected with the mounting seat 2. The mounting seat 2 can be fixed on the mounting part 12 by injection molding, and the mounting seat 2 is fixedly connected with the mounting frame in the atomization device.

[0032] The circumferential surface of the insertion part 11 is provided with a groove, which can be arranged in a spiral or curved manner on the circumferential surface of the insertion part 11 to cover only the circumferential surface of the insertion part 11. The groove of the insertion part can be prepared by laser engraving or etching.

[0033] The heating structure 111 and the temperature measuring structure 112 are arranged in the groove of the insertion part 11. The heating structure 111 and the temperature measuring structure 112 can be in close contact with each other or arranged separately. The heating structure 111 and the temperature measuring structure 112 are independent of each other. The heating structure 111 can be a thin nickel sheet, nickel-chromium alloy, aluminum, ferritic stainless steel, or other resistance heating materials. The heating structure 111 can convert electrical energy into heat energy to heat the atomized substrate. The insertion part 11 is made of a heat-conducting material, such as quartz, so that the heat generated by the heating structure 111 can be uniformly transmitted to the circumferential surface of the insertion part 11 to achieve uniform heating of the atomized substrate. The temperature measuring structure 112 can be made of platinum, copper, nickel, iron, germanium, indium, thermocouple alloy, and rhodium-iron alloy. The temperature measuring structure 112 measures the heating temperature by measuring the change in resistance value. The real-time heating temperature measured by the temperature measuring structure 112 controls the heating temperature of the device to improve the heating temperature accuracy.

[0034] The heating structure 111 and the temperature measuring structure 112 can be adhered in the groove of the insertion part 11 by high-temperature resistant glue. The heating structure 111 and the temperature measuring structure 112 can also be clamped in the groove of the insertion part 11 by extrusion deformation.

[0035] The heating structure 111 and the temperature measuring structure 112 are respectively connected to independent wires to realize electrical connection between the heating structure 111 and the temperature measuring structure 112 and the circuit board in the atomization device.

[0036] In this embodiment, the insertion part 11 gradually decreases in the direction away from the mounting part 2, that is, the second end of the insertion part 11 gradually decreases in the direction of the first end. The gradual decrease refers to the peripheral outer diameter of the insertion part 11. The insertion part 11 can have a conical structure. The circumferential surface of the insertion part 11 has a certain inclination angle relative to the central axis, and the inclination angle a is 0.5-2°. Preferably, the inclination angle a of the circumferential surface of the insertion part 11 relative to the central axis is 0.5°. The insertion part 11 is slightly inclined. In use, the first end of the insertion part 11 is located at the upper end, and the second end of the insertion part 11 is located at the lower end. The upper end of the insertion part 11 is smaller than the lower end. This is beneficial for the insertion of the insertion part 11 into the atomized substrate. In addition, a slope is formed on the circumferential surface of the insertion part 11. The tobacco residue generated by heating the atomized substrate will slide down to the bottom under the action of gravity without being adhered to the insertion part 11, thereby maintaining the cleanliness of the heating body 1 and reducing the cleaning difficulty of the heating body 1.

[0037] The diameter of the insertion portion 11 can be set as required, for example, the diameter of the second end of the insertion portion 11 is 2.4 mm.

[0038] In other embodiments, the insertion portion 11 can also be a polygonal cone structure, and an inclined circumferential surface can be formed on the insertion portion 11, so that the tobacco residue can be discharged to the bottom of the insertion portion 11 and not adhere to the insertion portion 11.

[0039] In this embodiment, the first end of the insertion portion 11 can also be provided with a sharp cone structure, so that the insertion portion 11 is more easily inserted into the atomization substrate.

[0040] In this embodiment, since the insertion portion 11 of the heating body 1 is provided as a tapered structure away from the mounting portion 12, that is, the insertion portion 11 is a conical structure, when the insertion portion 11 is inserted into the atomization substrate for use, the upper end of the insertion portion 11 is smaller than the lower end, so that the tobacco residue generated by heating the atomization substrate will slide down to the bottom under the action of gravity, and will not adhere to the heating body 1, thereby preventing the heating body from being easily contaminated, and reducing the cleaning difficulty of the heating body.

[0041] In one embodiment, the circumferential surface of the insertion portion 11 is provided with an anti-adhesion layer, which wraps the heating structure 111 and the temperature measuring structure 112, and is the outermost structure of the insertion portion 11. The anti-adhesion layer has a smooth surface and has a lubricating effect, so that the tobacco residue generated by heating the atomization substrate is not easily adhered to the anti-adhesion layer, and the setting of the anti-adhesion layer can further reduce the adhesion of the tobacco residue to the insertion portion 11.

[0042] The mounting portion 12 can also be provided with an anti-adhesion layer, so that the outer surface of the entire heating body 1 has an anti-adhesion layer, which can have a better anti-adhesion effect.

[0043] The anti-adhesion layer includes one or more of a nano material and a graphite material, which can form a smooth surface and a lubricating surface, which is beneficial for the tobacco residue to slide along the surface of the insertion portion 11. In addition, the anti-adhesion layer can also be a high-temperature-resistant insulating material, which can provide insulation protection for the heating structure 111 and the temperature measuring structure 112, and the high-temperature-resistant anti-adhesion layer can also avoid melting during heating.

[0044] In one embodiment, the heating body 1 and the mounting seat 2 can be fixedly connected by clamping, interference fit, etc., and the mounting portion 12 of the heating body 1 and the mounting seat 2 are fixedly connected by clamping, interference fit, etc.

[0045] The middle part of the mounting seat 2 can be provided with an axial mounting hole 21, and the mounting portion 12 is inserted into the mounting hole 21 of the mounting seat 2.

The lower end of the mounting seat 2 is a U-shaped structure, and the opening end of the U-shaped structure is fixedly connected with the disc structure. The mounting portion 12 extends into the U-shaped structure through the mounting hole 21, and the U-shaped structure can protect the mounting portion 12 from physical interference with other structures in the atomization device. The U-shaped structure is also provided with a threading hole, so that the line connected to the mounting portion 12 can pass through the U-shaped structure and be electrically connected with the circuit board.

[0047] The disc structure of the mounting seat 2 is provided with a first clamping portion 22, which is a flange structure and can realize axial limiting of one end. The U-shaped structure of the mounting seat 2 is provided with a second clamping portion 23, which is a reverse hook type buckle structure and is used to pass through the mounting hole of the mounting frame to realize axial limiting of the other end. The combined action of the first clamping portion 22 and the second clamping portion 23 can clamp the mounting seat 2 on the mounting frame, and the mounting process of the mounting seat 2 only needs to press the mounting seat 2 downward along the axial direction to realize the mounting, which is convenient and stable.
