In order to ensure the heating effect of the aerosol-generated substrate product, it is necessary to ensure that after the heating component unit moves/rotates to the end position, the heating time at this position does not exceed the heating time at the same position.

In the aerosol generating device of the present invention and the process of generating the aerosol:

(1) Keep the position of the heated aerosol-generating base material unchanged, which is conducive to the convenience of inhalation and operation for users who use inhalation-type aerosol-generating devices;

(2) The heating part of the heating element can move relative to the heated aerosol-generating substrate product, which is beneficial to the fact that the aerosol composition generated by the entire aerosol-generating device will not change with time. The segment heating effect is better;

(3) The product structure of the present invention will not cause a substantial increase in the cost of the aerosol generating device, and the present invention has the advantages of low cost and high reliability.

It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes should fall within the protection scope of the appended claims of the present invention.

The patent of the present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the realization of the patent of the present invention is not limited by the above methods, as long as various improvements made by the method concept and technical solutions of the patent of the present invention are adopted, or no improvement is made. It is within the protection scope of the present invention to directly apply the concept and technical solution of the patent of the present invention to other occasions.
