This is a smoke absorber that can be clamped on the collar. It is very convenient to use. It only has a switch button and a knob to control the smoking intensity. It is an intuitive product. It allows smokers to avoid the embarrassment of social situations affecting others, and it can also reduce the presence of second-hand smoke in the environment, which is very helpful to people and the environment.
