Description

Aerosol generating device and using method thereof Technical Field The invention relates to the field of aerosol generating devices, in particular to an aerosol generating device and a using method thereof. Background As an option for consumers to reduce the harm caused by conventional tobacco, the development of new aerosol-generating articles has been rapid in recent years, and common aerosol-generating articles can be broadly classified into electronic cigarettes, heated cigarettes, and the like according to the form of aerosol-generating materials. The aerosol-generating materials used in electronic cigarettes are liquid materials, while the aerosol-generating materials used in heating cigarettes are solid materials, such as tobacco flakes, tobacco particles, cut filler, reconstituted tobacco, and the like. That is, the aerosol-generating article comprises a solid material that generates an aerosol, i.e., a solid aerosol-generating medium. Illustratively, during normal use of the solid tobacco media, the solid tobacco media is heated to temperatures above 200 ℃ without burning, thereby avoiding inhalation of harmful components of conventional tobacco products due to burning and high temperature (up to 800 ℃) degradation. Such an aerosol-generating article comprising a solid smoking material structurally comprises a smoking unit, a cooling unit, a filtering unit and a wrapping unit. The fuming unit is a substrate which is heated by the heating unit to generate inhalable aerosol, and can be the tobacco sheet, the tobacco particles and the like. Aerosol generating devices on the market are mainly divided into two main forms of internal heating and external heating according to the form of the heating body. The aerosol-generating device has a receiving portion comprising a cavity into which the aerosol-generating article is inserted, enabling the receiving of the aerosol-generating article. If internal heating is employed, a heating element (e.g., a heater pin, heater tab, etc.) extends into the receptacle and is inserted into the smoke generating cell of the aerosol-generating article, and heat conduction occurs from within the smoke generating cell to form an aerosol. If external heating is employed, heating elements (e.g., heating rings, wires, etc.) are disposed on the inner wall of the receiving portion and around the aerosol-generating article, with heat transfer from outside the smoke generating unit to form an aerosol. The aerosol generating device on the market at present can only be used for determining and adapting to the same aerosol generating product after the heating body is determined and designed, and the resistance during suction can not adapt to the difference of the requirements of different consumers due to the structural design determination. In addition, in the research and development process of new products, aerosol generating products with different specifications and absorption resistance parameters are required to be tested, and if the parameters cannot be adjusted, the aerosol generating device is frequently changed to perform experiments, so that the research and development efficiency is greatly reduced. Disclosure of Invention The invention aims to solve the technical problem that the existing aerosol generating device cannot be adapted to aerosol generating products with different specifications. In a first aspect, embodiments of the present invention disclose an aerosol-generating device comprising a receptacle for receiving an aerosol-generating article, and further comprising a length-adapting device for the aerosol-generating article, wherein the length-adapting device comprises: A length adjusting rod extending along a first direction, the first direction being consistent with the extending direction of the aerosol-generating product, the length adjusting rod being insertable into a receiving portion for receiving the aerosol-generating product along the first direction, an end face of the length adjusting rod at one end within the receiving portion for supporting the aerosol-generating product; and the operating part is connected with the length adjusting rod and used for driving the length adjusting rod to move along the first direction so as to adjust the insertion length of the length adjusting rod in the accommodating part. Because the length adapting device is arranged in the aerosol generating device, the length of the heated aerosol generating product can be conveniently adjusted by adopting the aerosol generating device of the invention so as to adapt to different types of aerosol generating products. For example, when performing the test, the aerosol-generating article to be tested may be first placed in the accommodating portion, and the operating portion may be adjusted according to the length of the aerosol-generating article smoking unit. Illustratively, when the length adapting device of the present invention needs to be converted from adapting an aerosol
