Description

Aerosol generating device capable of realizing bidirectional suction

Technical Field

The utility model belongs to the field of heating non-combustion cigarette smoking set, in particular to an aerosol generating device capable of pumping in two directions.

Background

With the improvement of living standard, people pay more and more attention to their health problems, and in recent years, the attention on the health problems of smoking is high. In order to meet the changing consumption requirements of various large enterprises at home and abroad, various completely hollow tobacco products for replacing the traditional cigarettes are developed in a dispute. Among these growing fully hollow tobacco products, electronic cigarettes and heat-not-combusted cigarettes are superior.

The electronic cigarette serving as an electronic product is expanded and applied in the tobacco industry, and has the advantages that the smoking variability is strong, the smoke smoking taste can be randomly regulated and controlled by adjusting components of tobacco tar, but the taste, particularly the heat sensation, of the smoke is generated mainly through an electronic atomizer, and is still different from the traditional cigarette which generates smoke through heating, so that the acceptance of old smokers is poor.

The heating non-combustion cigarette is characterized in that a smoking section of the heating cigarette generates smoke, the acceptance of the smoke taste is good, the current market-oriented heating non-combustion cigarette mainly comprises a smoking core material section, a hollow supporting section, a cooling section and a filter tip section, the smoking core material section is a reconstituted tobacco sheet filled orderly or disorderly, and when the reconstituted tobacco sheet is heated, essence, spice and a smoking agent loaded on the reconstituted tobacco sheet are evaporated to generate smoke. However, the existing cigarette which is not heated and combusted has some problems, such as easy deformation of a temperature reduction section, overheating of smoke temperature and the like. To this end, we have devised "a rod-shaped smoking segment and method of making the same and a tobacco rod comprising the same" (patent application No. 201920751936.6). In the subsequent development process, the smoking section is found to have the effect of cooling, so that a bar-shaped cigarette and a preparation method thereof are designed (the patent application number is 201910507012.6); however, the cigarettes of the two designs still have a defect that the utilization rate of the smoke agent and the essence and flavor is not high. This phenomenon is not only found in cigarettes of such rod-shaped smoking segments, but is also quite evident in conventional heated non-burning cigarettes (e.g., iQOS and GLO). The residue rate of the smoke agent in the iQOS cigarette after suction is still 50% -60% of the original amount, the residue in GLO is slightly lower, but the residue rate is about 45% -50%, and the residue rate in the cigarette is about 50% -65%. The defect not only increases the difficulty of guaranteeing the amount of the smoke, but also seriously wastes the smoke agent and the essence and spice, and improves the production cost of the product.

SUMMERY OF THE UTILITY MODEL
