[0033] The technical solution in this application will be described clearly and completely below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0034] See also Figure 1-3 The present application provides a heating element 10. The heating element 10 is used to heat a cigarette product placed in an electronic smoking device.

[0035] The heating element 10 includes a bearing column 11 and a heating wire 12. The heating wire 12 surrounds the bearing column 11. The bearing column 11 supports the heating wire 12. The bearing column 11 is an integrally formed columnar structure. The heating wire 12 is detachably surrounded and sleeved on the bearing column 11.

[0036] See also Figure 4 , the bearing column 11 includes a first end face 111 and a second end face 112 that are arranged opposite to each other. A side face 113 is connected between the first end face 111 and the second end face 112. The side face 113 has a plurality of grooves 114. The grooves 114 are formed by being recessed from the side face 113 toward the central axis 11a of the bearing column 11. The grooves 114 extend from the first end face 111 to the second end face 112. The groove 114 has a first recessed surface 1140a. The first recessed surface 1140a includes a first sub-surface 1141 and a second sub-surface 1142. The first sub-surface 1141 and the second sub-surface 1142 intersect each other perpendicularly. The angle between the first sub-surface 1141 and the second sub-surface 1142 of the groove 114 is a right angle. The intersection line 1143 of the first sub-surface 1141 and the second sub-surface 1142 is parallel to the central axis 11a. In other embodiments, the included angle between the first sub-surface 1141 and the second sub-surface 1142 may also be an acute angle or an obtuse angle.

[0037] See also Figure 5In one embodiment, the groove 114 of the bearing column 11 may have a second concave surface 1140b. The second concave surface 1140b is a curved surface. Since the second concave surface 1140b is a curved surface, the difficulty of mold opening is simplified during the process of manufacturing the bearing column 11, and the production cost is saved.

[0038] See also Figure 6 In one embodiment, the groove 114 of the bearing column 11 may have a third recessed surface 1140c. The third recessed surface 1140c includes a third sub-surface 1145, a first curved surface 1146 and a fourth sub-surface 1147. The first curved surface 1146 is connected between the third sub-surface 1145 and the fourth sub-surface 1147. The third sub-surface 1145 and the fourth sub-surface 1147 are perpendicular. The third sub-surface 1145 and the fourth sub-surface 1147 are planes. The first curved surface 1146 is an arc surface. Since the third recessed surface 1140c has the structural characteristics of a combination of a curved surface and an arc surface, in the process of manufacturing the bearing column 11, the bearing column 11 can flexibly match the curved surface and the arc surface according to the different positioning positions and diameters of the heating wire 12, thereby increasing the adaptability of the product.

[0039] The material of the supporting column 11 can be Teflon or polyetheretherketone (Polyetheretherketone, Peek).

[0040] See also Figure 2-3 The heating wire 12 surrounds the supporting column 11. The heating wire 12 includes a plurality of horizontal portions 121 and a plurality of vertical portions 122. The horizontal portions 121 and the vertical portions 122 are connected at intervals. Figure 7 The horizontal portion 121 includes a first horizontal branch 1211 located at the first end surface 111 and a second horizontal branch 1212 located at the second end surface 112 . The vertical portion 122 is disposed in the groove 114 .

[0041] See also Figure 2-3 The heating element 10 further includes a sleeve 13. The sleeve 13 sleeves the bearing column 11 and the heating wire 12. The sleeve 13 includes a needle portion 131 and a base portion 132. The base portion 132 is located at one end of the needle portion 131. The needle portion 131 is used to insert the cigarette product. The sleeve 13 is made of zirconium oxide.

[0042] The sleeve 13 made of zirconium oxide provided by the present application has the following advantages over the sleeve made of alumina in the prior art: First, due to the large specific heat capacity of zirconium oxide, when the sleeve of the same volume absorbs the same amount of heat, the sleeve 13 made of zirconium oxide has the advantages of stable temperature rise and uniform temperature, which is conducive to uniform heating of the cigarette products of the electronic cigarette set, making the cigarette products taste good when smoked, and improving the product experience of the electronic cigarette set; Second, zirconium oxide has the characteristics of small particle size after sintering, and has high surface finish after polishing. When the sleeve 13 made of zirconium oxide is applied to the electronic cigarette set, the sleeve 13 is not easy to adhere to ash and has the advantage of being easy to clean. The surface finish of the sleeve 13 is greater than ▽9; Third, the toughness of zirconium oxide is greater than that of alumina, which solves the problem that the sleeve made of alumina is easy to break due to high brittleness during use.

[0043] The heating element 10 further includes a bearing base 14. The bearing base 14 is sleeved on the base portion 132 of the sleeve 13. The bearing base 14 includes a plurality of buckle portions 141. The buckle portion 141 is located at one end of the base portion 132 away from the needle portion 131. The buckle portion 141 is used to buckle the heating element 10 with other components in the electronic smoking device. In this embodiment, the buckle portion 141 extends in a direction away from the base portion 132 and away from the needle portion 131, and forms a hook 1411 at the free end 141a, and the hook 1411 is used to buckle the heating element 10 with other components in the electronic smoking device.

[0044] The bearing base 14 is made of plastic. The bearing column 11 and the heating wire 12 are assembled by inserting them into the sleeve 13, and the bearing column 11, the heating wire 12 and the sleeve 13 are put into a mold for making the bearing base 14. The bearing base 14 is formed and sleeved on the sleeve 13 by injection molding. The first end 14a of the bearing base 14 abuts against the end surface of the base portion 132 of the sleeve 13 facing the needle portion 131. The second end 14b of the bearing base 14 abuts against the end surface of the base portion 132 of the sleeve 13 away from the needle portion 131, and the bearing column 11 and the heating wire 12 are encapsulated in the sleeve 13. By forming the bearing base 14 through injection molding, and encapsulating the bearing column 11 and the heating wire 12 in the sleeve 13, the alignment process of the bearing column 11, the heating wire 12, the sleeve 13 and the bearing base 14 during the assembly of the electronic cigarette device can be omitted. The alignment process is the process of calibrating the verticality of the heating element when the heating element is installed in the electronic cigarette device. Furthermore, by forming the bearing base 14 through injection molding, and encapsulating the bearing column 11 and the heating wire 12 in the sleeve 13, the gap between the bearing base 14 and the sleeve 13 can be avoided, and the ash or dust can be prevented from entering the sleeve 13 during the use of the electronic cigarette device, which affects the heating performance of the electronic cigarette device.

[0045] The heating element 10 further includes an insulating tube 15. The insulating tube 15 is sleeved on the end of the heating wire 12 to insulate and protect the end of the heating wire 12.
