Aerosol generating device

Abstract

The invention provides an aerosol generating device, comprising: an aerosol generating substrate that generates inhalable aerosol, and a filter tip connected to the aerosol generating substrate; the filter tip includes a first adsorption unit filled with a filter medium and has The second adsorption unit of the gas mist channel and the gas mist collision wall, the first adsorption unit is located at the gas mist outlet end of the second adsorption unit; wherein the gas mist flows along the gas mist channel and collides with at least part of the gas mist collision Behind the wall there is a flow tendency along the circumference of the second adsorption unit. It can improve the aerosol filtering conditions and obtain the ideal aerosol deposition effect.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a cigarette product with a filtering structure, and in particular to an aerosol generating device. Background technique [0002] At present, there are various types of cigarette products on the market. Generally, ordinary cigarettes include an aerosol generating matrix composed of shredded tobacco that generates composite aerosol and a filter tip for filtering out some harmful substances in the composite aerosol. The customary filter generally consists of two sections. In order to improve the filtering effect, the R&D personnel in the industry consider filling the filter strip of one section of the filter with a high-efficiency adsorption material such as activated carbon. Although such a setting can filter more harmful substances to a certain extent, but While improving the filtering capacity, it will also enhance the overall absorption resistance of the filter, and the filtering capacity...

Problems solved by technology

The disadvantage of this product is that it requires additional configuration and needs to be carried with you, and after multiple uses, this filter will be contaminated with a greater tar smell than ordinary cigarettes

At the same time, the product also further increases the suction resistance

[0005] Technicians in the industry consider transplanting the filter adsorption structure of cigarette holder products into ordinary cigarettes. For example, Chinese patent (publication number CN1747664A) discloses a transparent adsorption filter cigarette, which improves the filter structure of the cigarette and adds a section Adsorption filter, and the adsorption filter is placed between two sections of filter rods, thereby realizing the filtration of harmful substances such as tar and the visualization of harmful substances. However, the actual filtering effect of this product is better than that of ordinary filter cigarettes. Improved, but still not perfect
