As shown in fig. 1, the heating element of the present invention is composed of a main body 1 and a tip 2 at one end of the main body. The tip 2 has a conical shape, and may be, for example, a conical shape or a pyramid shape. When the heating element pierces the tobacco product in the electronic smoking article, the shape gradually increases the piercing area of the tobacco product as the tip portion 2 gradually enters, so that the tobacco product can be loosened, and the heat transfer effect and the heating uniformity are improved.
The main body portion 1 connected to the tip portion 2 is rod-shaped or rod-shaped and is constituted by three sides so that its cross section is in a three-fork shape. As shown in fig. 2, the side surface of the main body 1 is preferably a curved surface shape concave toward the axis of the main body, and compared with a planar shape, the curved surface shape can increase the area of the side wall of the heating element, thereby increasing the arrangement space of the heating resistance wires 3 on the side surface of the main body, ensuring faster and more uniform heating of tobacco, improving the utilization rate of tobacco products, and reducing the occurrence of the phenomenon of tobacco powder wall hanging. In addition, as can be seen from fig. 2, the adjacent concave curved surfaces can form a more sharp main body portion side edge, which is matched with the tip end portion, so that the penetration effect of the heating element and the loosening effect after penetrating into tobacco products can be further improved.
Although the heating elements shown in fig. 1-3 are shown as a unitary, non-detachable, solid structure, the body portion 1 and the tip portion 2 may alternatively be detachably connected to each other, for example, by a threaded connection, a snap-fit connection, or a magnetic connection. The detachable split structure can increase the degree of freedom of the use of the heating element, for example, when the body portion 1 or the tip portion 2 is damaged, a user can conveniently replace the damaged portion by the detachable structure; when the heating effect of the main body 1 is not suitable or ideal, a user can conveniently replace the suitable main body 1 through a detachable structure; when maintenance cleaning of the heating element is required, the user can conveniently disassemble the main body portion and the tip portion through the detachable structure so as to more thoroughly clean the heating element. In addition, the heating element can also adopt a hollow structure, and the hollow structure is beneficial to saving materials and reducing cost.

The resistance heating part 3 can adopt heating resistance substrates, the arrangement mode of the substrates can be one circle as shown in the figure or can be multiple circles, but a certain distance is kept to prevent overheating. The heating resistor substrates and the temperature control wires on the side surfaces are respectively and directly connected with the battery.
Specific example 2:

Example 3
As shown in FIG. 5, the heating element is a tab, three tabs with resistive heating substrates on the inner cores are fixed in the slot, and in this embodiment, the slot is three-fork shaped, so that the whole surface is smoother and curved, and the friction resistance is small.
Example 4
As shown in fig. 6, the heating element is an insert sheet, three insert sheets with resistance heating substrates in the inner core are fixed in the insert slot, in this embodiment, the insert slot is circular, and a temperature control line (i.e. a temperature control part) is arranged at the axis of the main body part 1, so that the insert sheet is more stable in the insert slot and is not easy to bend.
Example 5
As shown in fig. 7, the heating element is a core type, and the resistance heating portion 3 is a core of the main body portion 1. Since the main body 1 is made of a high-temperature-resistant insulating material, and the resistance heating portion 3 is made of a metal material, the two materials can be mixed and do not react, and the resistance heating portion 3 can be placed as an inner core in the main body 1, and the inner core resistance heating portions of the main body are arranged in a three-fork shape in this embodiment.
Example 6
As shown in fig. 8, the heating element is a core type, and the resistance heating portion 3 is a core of the main body portion 1. Since the main body 1 is made of a high-temperature resistant insulating material, and the resistance heating portion 3 is made of a metal material, the two materials may be mixed and not reacted, and the resistance heating portion 3 may be placed as an inner core in the main body 1, and the inner core resistance heating portion of the main body is annular in this embodiment.
Example 7
As shown in fig. 9, the heating element is a core type, and the resistance heating portion 3 is a core of the main body portion 1. Since the main body 1 is made of a high-temperature resistant insulating material, and the resistance heating portion 3 is made of a metal material, the two materials can be mixed and do not react, and the resistance heating portion 3 can be placed as an inner core in the main body 1, and the inner core resistance heating portion of the main body in this embodiment has a curved triangle shape.
