Description

Fire cover, burner and kitchen range Technical Field The utility model relates to the technical field of stoves, in particular to a fire cover, a combustor and a stove. Background Gas cookers are indispensable living appliances in daily life. At present, a fire cover in the gas cooker is generally made of copper or stainless steel, and the fire cover made of copper has good heat conductivity, so that heat generated by flame can be transferred to a bottom of a pot, and the combustion efficiency of the gas cooker is improved. And the fire cover made of stainless steel material can have lower manufacturing cost, thereby meeting the purchase demands of more people. However, the copper fire cover is susceptible to oxidation reaction with oxygen in the air under high temperature environment, thereby affecting the aesthetic property of the fire cover. Stainless steel fire cover produces the rust easily after using for a certain time, greatly influences rust-resistant effect and the aesthetic property of fire cover. Disclosure of utility model In order to at least partially solve the problems existing in the prior art, according to an aspect of the present utility model, a fire cover is provided, and the technical scheme is as follows. The fire cover comprises an alloy body, a first material layer and a second material layer. The alloy body encloses and closes and form the gas mixing chamber, and the alloy body has the first surface that is located the gas mixing chamber outward. A first material layer is formed on the first outer surface, the first material layer having a second outer surface remote from the first outer surface. The second material layer is formed on the second outer surface, and at least part of the first material layer is exposed outside the second material layer. The first material layer is made of a corrosion-resistant material, and the second material layer is made of a high-temperature-resistant material. According to the fire cover, the alloy body made of the alloy material is low in manufacturing cost, high in strength and toughness, the first material layer formed on the first outer surface of the alloy body can improve corrosion resistance of the alloy body, the second material layer can be formed on the second outer surface of the first material layer so as to improve the pollution resistance of the fire cover, and the first material layer and the second material layer which are sequentially arranged outside the alloy body can effectively improve corrosion resistance, pollution resistance and attractive appearance of the fire cover.
