Abstract
The invention provides an ignition and flame-out protective device used on an infrared ray stove. The device is arranged on an air outlet port on the inner side wall of a central ventilation channel of a burner and comprises a high-temperature resistant insulation sleeve, an electric conduction needle and an electrode piece, wherein the high-temperature resistant insulation sleeve is arranged inside the central ventilation channel; the electric conduction needle is positioned inside the high-temperature resistant insulation sleeve; the lower end of the electric conduction needle penetrates through the high-temperature insulation sleeve to connect with an electronic control system inside the stove; and the electrode piece is arranged on the upper end of the electric conduction needle through a electric conduction connector. By adopting the scheme, when the stove is ignited, backflow is formed after a gas flow is obstructed by the electrode piece, and a pulse electric spark released by a discharge electrode ring ignites the gas in a backflow zone quickly, and meanwhile, the ignition rate of the stove is greatly improved through multi-point electro-discharging. The electrode piece ensures that the central ventilation channel can not be exposed, greatly improves aesthetic properties of the stove, solves ignition insecurity under the infrared ray stove, and greatly enhances the popularization effect of the infrared ray stove.
