The invention discloses a gas stove with a separable control piece. The gas stove comprises a panel, a fuel gas proportional valve, the control piece, a position detection unit, and a main controllerunit, wherein the panel is provided with a combustor; an input end of the fuel gas proportional valve is connected with an external air inlet pipe, and an output end of the fuel gas proportional valveis connected with the combustor; the control piece is separated from the panel and is in contact with one side of the panel; the position detection unit is arranged on the other side of the panel andcan detect the position information of the control piece; and the main controller unit is electrically connected with the position detection unit and is electrically connected with a control end of the fuel gas proportional valve and a igniter to control the fuel gas proportional valve to work according to a detection result of the position detection unit. The combustion of the combustor can be stopped after the control piece is far away from the panel, and accidents are prevented.
