Abstract

The utility model relates to an experimental device for exploring that smoking is harmful to health, which comprises an injector, a latex tube, a test tube with a branch tube, a one-way valve, a conduit, an iron stand, an iron clamp, a test tube, a cigarette, a cigarette holder, a rubber plug and a conical flask, the branch tube opening of the test tube with the branch tube is connected with the injector through the latex tube, the rubber plug of the tube opening is inserted into the one-way valve and the conduit, and the test tube opening is provided with a double-hole rubber plug with the conduit. The test tube with the branch tube and the test tube are respectively fixed on the iron stand and are clamped by the iron clamp, one hole of the double-hole rubber plug on the conical flask is connected with the cigarette holder, the other hole is connected with the conduit, and finally, the interfaces of the conduits are connected by the latex tubes. The injector is pushed and pulled to suck smoke generated by burning cigarettes into the container, and the smoke acts with chicken blood or a series of reagents to present color and state changes, so that smoke components are explored. The device is simple in manufacturing material, cheap and easily available in reagent and visual in experimental phenomenon, can better feel the harm of smoke to health, and enhances the environment-friendly awareness that people do not smoke and are far away from second-hand smoke.

Description

[0001] 1. Technical field [0002] The invention relates to the technical field of physical exhibition and experimental teaching of public health and public welfare publicity, and specifically relates to the technical field of teaching of life science and community activity experiments to explore harmful components of cigarette smoke. [0003] 2. Background technology [0004] According to a survey, 48% of lung cancer patients smoke, and 37% live or work with smokers for a long time. About 1.2 million people die from smoking every year. [0005] It is common knowledge that smoking is harmful to health, but it is hard for people to imagine how harmful the smoke of cigarettes is. Because, the smokers we saw didn't get sick or lose weight immediately, on the contrary, people got excited after smoking to help them think. Therefore, if there is a set of experimental devices to visually demonstrate the poison of smoke, the health education for young people will be more effective. ...
