    • In a kerosene heater in which combustion is effected by means of a wick (3), a wick raising and lowering mechanism (5) for raising and lowering the wick (3) and a fine-regulatable wick raising and lowering mechanism (20) for finely controlling the combustion rate of the wick (3) are provided. The fine-regulatable wick raising and lowering mechanism (20) generally includes a rack (23), a wick-raising pinion (32), a wick-lowering pinion (34), a first manually operable member (27) for driving the wick-raising pinion (32), and a second manually operable member (28) for driving the wick-lowering pinion (34). The combustion rate can be finely, easily, and safely regulated by means of an operation between the rack (23) and the wick-raising and lowering pinions (32, 34).
    • 在燃烧通过灯芯(3)进行燃烧的煤油加热器中,用于升高和降低燃烧芯(3)的油芯升降机构(5)和一个可调节油芯升降机构(20),用于 提供了精细控制燃烧芯(3)的燃烧速率的方法。 精细调节芯吸升降机构(20)通常包括齿条(23),吸芯升降小齿轮(32),吸芯小齿轮(34),第一可手动操作的构件(27),用于驱动芯 以及用于驱动吸芯降低小齿轮(34)的第二手动操作构件(28)。 可以通过在齿条(23)和上升和下降小齿轮(32,34)之间的操作来精细地,容易地并且安全地调节燃烧速率。
