[0032] In addition, features described in the specification, operations or characteristics can be combined in any appropriate manner to form various embodiments, and the steps involved in each embodiment can be sequentially adjusted or adjusted in a manner that can be apparent to those skilled in the art. Therefore, the description and drawings are only for the purpose of clearly describing one embodiment, and do not mean the necessary composition and / or order.

The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.
[0034] In the related art, the heating assembly with two holes has a distance without a heating body in the circumferential direction, which makes the liquid guide medium not heated by the heating body in a distance in the circumferential direction, and further makes the aerosol generating substrate on the liquid guide medium not fully generate aerosol. And the heating assembly has three pins, which has high production cost.
[0035] In view of this, the application provides a heating assembly, an atomizing core and an atomizing device, so that the liquid guide medium has a heating body heating at any part in the circumferential direction, improving the utilization rate of the aerosol generating substrate on the liquid guide medium, and using two pins, which reduces the production cost compared with the technical solution of using three pins.
[0036] Please refer to Figure 1 and Figure 2 The atomizing device includes an atomizing core 100, the atomizing core 100 includes a heating assembly 10 and a liquid guide medium 20, the liquid guide medium 20 has a containing cavity 21, and the heating assembly 10 is installed in the containing cavity 21.
[0037] The liquid guide medium 20 is a component for guiding the aerosol generating substrate, is provided with a plurality of channels for transmitting the aerosol generating substrate, and can transmit the aerosol generating substrate from the side of the liquid guide medium 20 away from the containing cavity 21 to the side of the liquid guide medium 20 close to the containing cavity 21, and can be a liquid guide cotton or a liquid guide ceramic.
[0038] The heating assembly 10 is a component for heating the aerosol generating substrate to generate aerosol.
[0039] Please refer to Figure 3 The heating assembly 10 includes a heating body 11, a first pin 12 and a second pin 13. The heating body 11 includes a plurality of heating wires 111, each of which is in a complete annular structure, the central axes of the plurality of heating wires 111 are collinear, and the plurality of heating wires 111 are arranged in the axial direction of the heating wire 111.

[0040] The heating element 11 is a component for heating the aerosol generating substrate to generate an aerosol. When the heating element 11 is powered, heat is generated to heat the aerosol generating substrate. The first pin 12 and the second pin 13 are electrically conductive components for electrically connecting the heating element 11 and a power supply device (such as a power source). One of the first pin 12 and the second pin 13 is connected to the positive pole of the power supply device, and the other is connected to the negative pole of the power supply device. When the heating assembly 10 is assembled with the liquid guide medium 20, the heating element 11 is installed in the accommodation cavity 21 of the liquid guide medium 20 and in contact with the inner wall of the accommodation cavity 21, and the first pin 12 and the second pin 13 extend out of the accommodation cavity 21 of the liquid guide medium 20.
[0041] With the above technical solution, the heating element 11 is arranged to include a plurality of heating wires 111, each of which has a complete annular structure, the central axes of the plurality of heating wires 111 are collinear, and the plurality of heating wires 111 are arranged along the axial direction. In this way, the heating element 11 is arranged in a closed manner in the circumferential direction, and there is no interval. Therefore, the liquid guide medium 20 can be heated by the heating element 11 at any position in the circumferential direction, and the utilization rate of the aerosol generating substrate on the liquid guide medium 20 can be improved. Moreover, the heating assembly 10 is provided with two pins, i.e., the first pin 12 and the second pin 13. Compared with the technical solution of arranging three pins, the number of pins is reduced, and the production cost is reduced.

It can be understood that in other embodiments, the line connecting the first connection site 112 and the second connection site 113 of the same heating wire 111 can also deviate from the central axis of the heating wire 111.
[0044] In an embodiment, the line connecting the first connection sites 112 of the plurality of heating wires 111 is parallel to the central axes of the heating wires 111, and the line connecting the second connection sites 113 of the plurality of heating wires 111 is parallel to the central axes of the heating wires 111.

In this way, the liquid medium 20 is heated by the corresponding heating wire 111 every same distance along the axial direction, which is beneficial to uniformly heat the liquid mediated by the liquid medium 20. Of course, in other embodiments, the plurality of heating wires 111 can be arranged non-equidistantly along the axial direction.
[0046] In an embodiment, the heating assembly 10 further comprises a reinforcing rib (not shown in the figure), which is connected between two adjacent heating wires 111. By arranging the reinforcing rib, the overall strength of the heating body 11 is improved. Of course, in specific applications, the heating assembly 10 can also not be provided with a reinforcing rib.

[0048] In an embodiment, the heating wire 111 is in any one of a circular ring structure, an elliptical ring structure, a rectangular ring structure, and a regular polygon ring structure. In specific implementation, the shape of the heating wire 111 is matched with the shape of the accommodation cavity 21 of the liquid medium 20, so that when the heating body 11 is installed in the accommodation cavity 21, the heating wire 111 contacts the inner wall of the liquid medium 20 in the circumferential direction of the heat-conducting medium. In this embodiment, the heating wire 111 is in a circular ring structure, and correspondingly, the cross section of the accommodation cavity 21 of the liquid medium 20 is circular.
[0049] In an embodiment, the wire diameters of the plurality of heating wires 111 are the same, the cross-sectional shapes of the plurality of heating wires 111 are the same, and the materials of the plurality of heating wires 111 are the same. In this way, the heating performance of each heating wire 111 is the same. The cross section of the heating wire 111 can be in any one of a circular shape, an elliptical shape, a rectangular shape, and a regular polygon shape. It can be understood that in other embodiments, at least one heating wire 111 has a wire diameter different from that of the other heating wires 111, or at least one heating wire 111 has a cross-sectional shape different from that of the other heating wires 111, or at least one heating wire 111 has a material different from that of the other heating wires 111.
