Abstract

The invention provides an aerosol generating device, comprising a gas pipeline, a liquid pipeline and an aerosol pipeline. A gas outlet is arranged in the pipe wall of the gas pipeline; the gas pipeline is communicated with the end opening located at the first end of the aerosol pipeline through the gas outlet; the pipe wall of the aerosol pipeline is provided with a liquid inlet; the liquid pipeline is communicated the aerosol pipeline through the liquid inlet; the diameter of the gas pipeline is greater than the diameter of the aerosol pipeline; the diameter of the aerosol pipeline is greater than the diameter of the gas outlet; and the liquid inlet is close to the first end. According to the aerosol generating device, high pressure gas first passes through the gas pipeline at first, then through the gas outlet with a small diameter and finally through the aerosol pipeline; because of high pressure of the gas, the flow rate at the small outlet increases sharply, cross section increases from the small outlet to the aerosol pipeline, so siphonage is generated, which allows medicinal liquid to be sucked from the liquid pipeline to places surrounding air flow; and the high-speed air flow cuts the liquid into particles of various sizes and ejects the particles out at a high speed, thereby forming aerosol.

Description

technical field [0001] The invention relates to the technical field of aerosol generation, in particular to an aerosol generating device. It can be used for the safety evaluation of inhalation toxicology drugs, the inhalation experiment research of acute toxicity of pesticides, the construction of various animal disease models and the experimental research of their drug efficacy, the research of the influence of air pollutants on the animal respiratory system, etc. Background technique [0002] Inhalation toxicology is a science that studies the various conditions, laws and mechanisms of the occurrence, development and elimination of the toxic effects of inhalable substances on the body, as well as the risk assessment of inhalable substances. His professional research contents mainly include: the physical and chemical properties of various substances in the air; the basic biology of the respiratory tract; the deposition and retention of inhaled substances in the body and the...
