Electronic cigarette atomized aerosol sampling device, testing device and testing method

Abstract

The invention discloses an electronic cigarette atomized aerosol sampling device, testing device and testing method. The sampling device includes a control valve, a power source and a smoke suction machine suction engine; the control valve is connected with an electronic cigarette and a gas supply device through pipelines respectively, a signal line of the power source for supplying power for theelectronic cigarette and a signal line of the control valve are electrically connected with the smoke suction machine suction engine. The device can test the concentration and particle size distribution of electronic cigarette atomized aerosol particles in real time. The problems that test results before and after testing are inconsistent because aerosol easily blocks a sampling valve inlet part is solved; with the addition of the power supply part controlled by the suction engine, the voltage change problem in the testing process of the electronic cigarette is reduced; the problem of matchingof the cigarette smoke flow and the inlet flow of an aerosol tester is solved, gas flow needs to be supplemented, and the inlet flow of the aerosol tester is met.

Description

technical field [0001] The invention relates to an electronic smoke aerosol sampling device, a testing device and a testing method. Background technique [0002] E-cigarettes are electronic products that mimic cigarettes and have the same look, smoke, taste and feel as cigarettes. It is a product that turns e-liquid into steam by atomization and other means, and then condenses to form an aerosol for users to inhale. Electronic cigarette atomizer is generally a heating element, which is powered by a battery to generate heat to volatilize the e-liquid next to it to form smoke. The smoke output and working status are controlled through the chip and air flow sensor. The nicotine in the e-liquid is atomized. When people smoke, the gaseous substances condense to form particles, simulating smoke, so that when people smoke electronic cigarettes, they can achieve the effect of "swallowing clouds and fog". E-cigarette smoke is also a typical aerosol. Studying the particle size distr...

AI Technical Summary

Problems solved by technology

The sampling device solves the technical problem of the aerosol condensation blocking the sampling pipe part when sampling in the existing electronic cigarette aerosol test system; at the same time, it improves the problem of aerosol changes caused by the voltage change of the electronic cigarette during the test process
