Background

At present, a gas warmer is a heating device adopting a gas combustion technology. The heating principle is that after the gas is combusted, the stainless steel mesh cover of the heater is continuously heated, the stainless steel mesh cover rapidly turns red and generates a large amount of infrared radiation to rapidly heat the surrounding environment. The warmer has high heat conversion efficiency, and almost all heat generated by combustion of gas can be used for warming. However, such a heater is often used for outdoor heating because it consumes oxygen in the surrounding environment.

In a gas warmer in the related art, a main ignition assembly comprises an ignition disc and a barrel-shaped stainless steel combustion net covering the ignition disc, wherein the ignition disc burns by taking natural gas as a raw material and heats the combustion net.

In view of the above-mentioned related technologies, the inventor believes that in the actual use process, circular air inlets are densely distributed on the surface of a common combustion net, so that the ignition plate can obtain enough oxygen to be fully combusted during combustion. However, in consideration of the structural strength of the combustion net, an enough gap needs to be reserved between adjacent air inlets, so that the whole air inlet area of the combustion net is reduced, the ignition plate is not favorable for carrying out sufficient combustion, and particularly, in a high-power combustion state, the condition that the combustion is insufficient due to insufficient air inflow of gas is easily caused, so that certain potential safety hazards are generated.
