Specifically, the heat generating layer 112 may be formed on the outer surface of the sidewall of the substrate 111 by silk-screen printing, sputtering, coating, printing, or the like.

As shown in fig. 3, the base 13 is annular and has a bottom wall and an annular side wall connected to the bottom wall, and the bottom wall and the annular side wall of the base 13 enclose to define a limiting cavity 131; part of the heating element 11 is inserted into the limit cavity 131 of the base 13. In this embodiment, the base 13 further has an end face deviating from the bottom wall thereof, specifically, a surface of one end of the base 13 deviating from the bottom wall thereof in the axial direction thereof, and the end face connects the inner wall face and the outer wall face of the annular side wall of the base 13; wherein, the axial direction of the base 13 is parallel to the inserting direction a (see fig. 4) of the heating element 11 into the base 13. The conductive member 14 includes a body portion 141 and an electrical connection portion 142 connected in this order; the main body 141 is located outside the base 13 and is used for coupling a power supply. Specifically, the body part 141 may pass through the conductive member to be coupled with a power source, thereby realizing that the power supply assembly 20 supplies power to the heat generating body 11. In this embodiment, a side of the sidewall of the base 13 facing away from the limiting cavity 131 and a side of the end of the base 13 facing away from the base 13 along the radial direction of the base 13 are both outside the base 13.

In an embodiment, please refer to fig. 4, fig. 4 is a schematic structural diagram of the conductive element and the base after assembly; at least part of the body 141 of the conductive element 14 is overlapped on the end face of the chassis 13; the term "lap joint" as used herein means that at least a part of the main body 141 is supported by the end surface of the base 13, i.e., the end of the base 13 supports the part of the main body 141 supported thereon; the electric connection part 142 and the body part 141 are connected to the part of the end face of the base 13 and are located on the inner side of the side wall of the base 13, so that after the heating element 11 is inserted into the limiting cavity 131 of the base 13, the electric connection part 142 of the conductive element 14 is in contact with the electrode 12 located on the outer surface of the heating element 11 to realize electric connection, and is in tight contact with the electrode under the action of gravity of the heating element 11, thereby effectively increasing the connection reliability of the two parts. Moreover, since at least a portion of the body 141 is overlapped on the end surface of the base 13, the conductive element 14 can be supported by the base 13, so that in the process that a portion of the heating element 11 is inserted into the base 13 and the electrical connection portion 142 of the conductive element 14 is pressed, the conductive element 14 can be tightly hung on the base 13 without relative displacement or separation with the base 13 along the axial direction of the base 13, the conductive element 14 can be accurately connected to the electrode 12, and the heating assembly 10 cannot normally work due to the misalignment of the electrical connection portion 142 and the electrode 12. It is understood that, corresponding to the electrodes 12, the conductive elements 14 are also plural in number and are arranged at intervals along the circumferential direction of the base so as to be connected with the plural electrodes 12 in a one-to-one correspondence, respectively. In the present embodiment, the number of the electrodes 12 is two, and the polarities of the two electrodes 12 are opposite, that is, one positive electrode and one negative electrode; correspondingly, two conductive elements 14 are connected to the positive electrode 12 and the negative electrode 12, respectively.

Specifically, as shown in fig. 4, the electrical connection portion 142 of the conductive element 14 includes a bending portion 1421 and an abutting portion 1422; the bending portion 1421 is connected to an end of the main body 141 close to the inside of the base 13, that is, an end close to the limiting cavity 131 of the base 13, and extends toward the center of the base 13; the contact portion 1422 is connected to one end of the bent portion 1421 remote from the body portion 141, and extends in the insertion direction a in which the heating element 11 is inserted into the base 13 so as to contact the electrode 12 located on the outer surface of the heating element 11.

In a specific embodiment, an included angle between the bending part 1421 and/or the abutting part 1422 and an insertion direction a of the heating element 11 inserted into the base 13 is greater than 90 ° and smaller than 180 °, that is, the included angle between the bending part 1421 and/or the abutting part 1422 and the insertion direction a is an obtuse angle, so that a blocking phenomenon when the heating element 11 is inserted into the base 13 and abutted against the electrical connection part 142 is reduced or avoided, so that the heating element 11 is more smoothly inserted into the base 13, which is not only convenient for installation, but also can avoid the heating element 11 from damaging the electrical connection part 142 in the process of being inserted into the base 13.

Specifically, the electrical connection portion 142 has elasticity, and may be an elastic conductive sheet, such as a copper alloy, a steel material, or the like, having elasticity. As shown in fig. 4, the electrical connection portion 142 is suspended in the base 13 at a first position, that is, as shown in fig. 5a, fig. 5a is a schematic view of the electrical connection portion in the first position; when the heating element 11 is not inserted into the base 13, the electrical connection portion 142 is specifically in the first position; and as shown in FIG. 5b, FIG. 5b is a schematic view showing the electrical connection part at a second position under the pressing of the heating element; after the heating element 11 is inserted into the base 13, the electric connecting part 142 is pressed by the heating element 11, and the electric connecting part 142 is elastically deformed and switched from the first position to the second position; at this time, the electrical connection portion 142 has an elastic force moving toward the first position, by which the electrode 12 and the electrical connection portion 142 are brought into close contact to achieve reliable connection therebetween. It can be seen that due to the elastic deformation of the electrical connection portion 142, α is greater than α ', where α' is an included angle between the bending portion 1421 and the abutting portion 1422 when the electrical connection portion 142 is at the first position; α is an included angle between the bending part 1421 and the abutting part 1422 when the electrical connecting part 142 is at the second position; meanwhile, due to the elastic deformation of the electrical connection portion 142 when the heating element 11 is inserted into the base 13, the included angle between the bending portion 1421 and/or the abutting portion 1422 and the insertion direction a of the heating element 11 into the base 13 is also increased to a certain extent, but still larger than 90 ° and smaller than 180 °. Specifically, the bending portion 1421 may be bent upward and downward along the insertion direction a of the heating element 11 around the connection portion of the bending portion 1421 and the main body 141, so as to switch between the first position and the second position.

With continued reference to fig. 4, in the embodiment, the body portion 141 of the conductive element 14 includes a first body portion 1411 and a second body portion 1412 electrically connected to each other; the first body portion is connected to the end face of the base 13, and the electrical connection portion 142 is connected to one end of the first body portion 1411 away from the second body portion 1412, so that the conductive element 14 is connected to the base 13, and thus when the heating element 11 is inserted into the base 13, the body portion 141 can support the conductive element 14 through the base 13, and thus in the process that part of the heating element 11 is inserted into the base 13 and extrudes the electrical connection portion 142 of the conductive element 14, the conductive element 14 can be tightly connected to the base 13 without relative displacement or separation between the conductive element 14 and the base 13 along the axial direction of the base 13, so that the conductive element 14 can be accurately connected to the electrode 12, and the heating assembly 10 cannot normally operate due to the misalignment between the electrical connection portion 142 and the electrode 12. Wherein, the second body portion 1412 extends along the axial direction of the base 13, that is, the second body portion 1412 extends along the longitudinal direction perpendicular to the radial direction of the annular sidewall of the base 13 and is located at the outer side of the sidewall of the base 13 for coupling with a power supply; it is easy to understand that the end of the second body portion 1412 away from the first body portion 1411 is used for coupling with a power supply, the connection method is less affected by the temperature of the heating element 11, the connection reliability is high, and the connection method has no limitation on the material of the heating element 11, and the application range is wider. Specifically, the end of the second body portion 1412 remote from the first body portion 1411 is connected to the conductive member, so that the conductive member 14 is coupled to the power supply, and the power supply assembly 20 supplies power to the heating body 11.

In the present embodiment, the conductive member 14 includes a body portion 141 and a plurality of electrical connection portions 142; the body 141 is arc-shaped, the plurality of electrical connection portions 142 are arranged at intervals along the circumferential direction of the body 141, or the plurality of electrical connection portions 142 are uniformly distributed in a preset area of the body 141; specifically, the first body portion 1411 is planar, an edge of the first body portion 1411 close to the electrical connection portion 142 and an edge of the first body portion close to the second body portion are arcs, the second body portion 1412 is an arc-shaped surface attached to an outer wall surface of the base 13, and the electrical connection portions 142 are distributed at intervals along the edge of the first body portion 1411 close to the electrical connection portion 142, or are uniformly distributed on the arc of the edge. The arrangement of the plurality of electrical connection parts 142 can increase the contact points of the conductive element and the electrode 12 on the heating element 11, so as to ensure that the heating element 11 can be effectively contacted with the electrical connection parts 142 when the circumferential deviation occurs in the base 13, and thus, the effective electrical connection between the heating element and the electrical connection parts is realized. In the present embodiment, the conductive member 14 includes one body portion 141 and two electrical connection portions 142.
