吸烟引起火灾的报道不少。我设计了一种自熄烟,在香烟的过滤嘴与烟的交界处放上一个小小的水囊,在吸烟时,不影响吸烟效果,而想把烟头熄灭时,只需轻轻地在香烟的过滤嘴上一按,水就从这个囊中向烟头方向射出,使烟头火熄灭。省新昌城关中学学生 There are many reports of fire caused by smoking. I designed a self-extinguishing cigarette with a small water bladder at the junction of the cigarette filter and the cigarette. When smoking, it does not affect the smoking effect. When I want to extinguish the cigarette, I just lightly smoke the cigarette. When the filter is pressed, the water is ejected from the capsule toward the cigarette butts to extinguish the cigarette.
