Device for demonstrating harm of smoking to health and manufacturing method thereof

Abstract

The invention provides a device for demonstrating the harm of smoking to health and a manufacturing method thereof. The device is characterized in that the device is mainly formed by a human body lung model made of plastics, and a smoking pipeline and a support thereof which are connected with the human body lung model, wherein the lung model consists of a transparent and elastic plastics shell and spongy filler wrapped in the shell, materials of the filler in the lung model contain color-changing agent or are coated with color-changing agent on the surface, one end of the smoking pipeline is connected with the lung module, and the other end of the smoking pipeline is branched into a branch pipe A and a branch pipe B. When the device is used, a cigarette is inserted into a round hole at the branch pipe A end and is ignited, the right lung part of the lung model is pinched and released repeatedly for simulating the smoking movement of the human body lungs, and meanwhile, the color of the filler in the right lung part of the lung model is observed to be changed into gray black from red. Through the bright color comparison of the gray right lung part and the ruddy left lung part, the principle and the phenomenon of harm of smoking to the lungs are concretely and visually demonstrated, so that a smoker can personally see the terrible phenomenon of the harm of smoking to the lungs, and is warned of no smoking and quit smoking.

Description

technical field [0001] The invention relates to a teaching appliance, in particular to a demonstrator that smoking is harmful to health and a manufacturing method thereof.
