Referring to fig. 1, an embodiment of the present invention provides an atomizer 100, which includes a main body 10, a power supply module 20, a control module 30, and an atomizing pipe 40. Wherein, the power supply module 20 is installed in the main body 10 for supplying power to the atomizer 100. The control module 30 is used for controlling the working state of the atomizer 100 according to user operation. The nebulizing tube 40 is surrounded by an inductive coil 50, the inductive coil 50 being capable of generating an alternating magnetic field which can penetrate the nebulizing tube 50 under the supply of an alternating current, thereby inducing the nebulizing tube 50 to react and generate heat to heat the aerosol-generating substrate to produce an aerosol.

The structure and the implementation of the atomizing tube 40 of the atomizer 100 of the present application will be described in detail below by taking various embodiments as examples. However, the following embodiments are only exemplary and do not limit the technical scope of the present application. In addition, for the sake of distinction, the reference numbers of the atomizing pipes 40 will be shown differently in different embodiments, and are not described herein.

Referring to fig. 2 and 3, in the first embodiment, the atomizing tube 40a is substantially cylindrical and forms an atomizing chamber 412a with two open ends along the axial direction, and the aerosol-generating substrate can be inserted into and pulled out of the atomizing tube 40a from one open end. The atomizing tube 40a includes an intermediate section configured as a heat generating region and a connecting section arranged at least one end of the intermediate section along its own axial direction, at least one of the connecting sections being configured as a non-heat generating region that can generate heat to bake the aerosol-generating substrate, the non-heat generating region then being kept at a lower temperature throughout.

Thus, at least one end of the heating area in the axial direction is provided with a non-heating area, so that heat generated by the heating area is not easily conducted to other components positioned on the axial direction of the atomizing pipe 40a under the blocking of the non-heating area, the service life of the components is prevented from being influenced by overhigh temperature, and meanwhile, the waste of energy is avoided.

As a preferred embodiment, the intermediate section is provided with connecting sections at both ends in the axial direction of the atomizing tube 40a, both of which are configured as non-heat-generating regions. Thus, the non-heat generating regions are disposed at both axial ends of the atomizing tube 40a, and the heat generating region is located between the two non-heat generating regions. Therefore, the heat generated by the heat generating region can be blocked by the non-heat generating regions at both ends in the axial direction thereof, preventing the heat from being conducted along both ends in the axial direction thereof.

It is understood that, in other embodiments, the non-heat-generating region is only disposed at one end of the heat-generating region in the axial direction of the atomizing tube 40a, so as to prevent the heat of the atomizing tube 40a from being conducted to the end where the non-heat-generating region is disposed, which is not limited herein.

In this manner, the heat generating layer 43a emits heat which is conducted through the primary tube 41a to the aerosol generating substrate in the nebulizing chamber 412a to generate an aerosol, whereas the primary tube 41a, which is not covered with the heat generating layer 43a, prevents heat from being conducted to other components located at both axial ends of the nebulizing tube 40 a.

Further, at least one limiting rib 414a extending into the atomizing chamber 412a is protruded from the inner surface of the main tube 41a, and the limiting rib 414a can extrude the aerosol-generating substrate to compress the circumferential dimension of the aerosol-generating substrate, thereby shortening the heat conduction distance and facilitating the heat of the heat-generating layer 43a to be transferred into the aerosol-generating substrate. Specifically, the main tube body 41a is provided with 3 to 8, preferably 4 to 6, limiting ribs 414, and each limiting rib 414a extends from one end of the main tube body 41a to the other end of the main tube body 41a along the axial direction of the main tube body 41 a. It is understood that the number and arrangement of the limiting ribs 414a are not limited thereto, and may be set as required to meet different requirements.
