Filling-type simple gas oven structure

Abstract

Filling-type simple gas oven structure including a top board, an oven seat, an upper oven body, a separating pad member, a lower oven body and a gas-filling device. The upper and lower oven bodies are mated with each other to form an oven body. Multiple gas reservoirs are continuously arranged in the oven body and communicate with each other via gas ways. The total capacity of the oven body for reserving the gas is increased so that the combustion time is prolonged. The gas-filling device provides double checking effect and prevents the gas from leaking out of the oven body so as to ensure security.
