Description

Technical Field

[0002] As a new type of tobacco, heated cigarettes are gradually being accepted by consumers due to their advantages such as harm reduction and multiple flavors, and the market size is gradually expanding. As low-temperature cigarettes, heated cigarettes mainly use heat to steam the smoking material to release a large amount of aerosol for inhalation at low temperatures, which can not only achieve a similar sense of satisfaction as cigarettes, but also reduce the production of harmful substances.

[0003] At present, the method of stabilizing and controlling aerosol release is mainly to add a smoking agent with glycerin as the main component to the smoking material, while reducing its water content.

[0075] A third filter 83 may also be provided on the recovery pipeline for filtering, so that the material recovered in the recovery box 82 is purer. More preferably, the liquid supply assembly 2 is provided with a first weight sensor 25, and the recovery box 82 is provided with a second weight sensor 84. The control module receives the signals of the first weight sensor 25 and the second weight sensor 84, and by comparing the weight changes, the actual amount of atomizer added can be obtained, and the operation of the gas supply assembly 1 and the liquid supply assembly 2 can be adjusted as needed to reduce the waste of atomizer.

[0076] Specifically, the weight reduction of the heating kettle 21 is set as Q1, which is the total amount of added material. The total amount of added material will not be completely absorbed; at the same time, the weight increase of the recovery box 82 is set as Q2, which is the atomizer that has not been absorbed. The atomizer dosage Q to be added is set according to the actual atomized weight. When Q1-Q2=Q, the addition amount requirement is met, and the spray component switch is turned off.

[0077] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
