The combustion chamber is located inside one end of the shell and is fixedly connected to the shell via a bracket. The gap between the combustion chamber and the shell forms a hot air chamber. The fan is located inside the other end of the shell. One end of the combustion chamber is inserted into the stove cover, and the burner is fixedly connected to the stove cover. The gas conduit communicates with the burner and the gas valve. The fan is opposite to the stove cover. The fan comprises a shell, a motor base, a brushless motor, and an impeller. The shell is square and has a central circular hole. The brushless motor is fixed to the motor base, one impeller is fixed to the brushless motor shaft, and the other impeller is fixedly connected to the motor base. The two impellers are arranged in a mirror image. The problem is that the burner is susceptible to backfire or unstable flame fluctuations due to wind influence. Utility Model Content
