[0024] Figure 1-5The first embodiment is shown: a premixed burner with a continuous flame, including an installation cylinder 1. A mixing cylinder 3 is fixedly connected to the inner wall of the installation cylinder 1 by a support rod 2. A combustion plate 9 is fixedly connected to the top of the inner wall of the mixing cylinder 3. A combustion hole is opened through the surface of the combustion plate 9. An air pipe 6 is connected to the bottom end of the mixing cylinder 3. The end of the air pipe 6 away from the mixing cylinder 3 passes through the installation cylinder 1 and extends to the outside of the installation cylinder 1. A main gas pipe 7 is connected to the installation cylinder 1. The main gas pipe 7 passes through the installation cylinder 1 and the mixing cylinder 3 and extends into the interior of the mixing cylinder 3. A mixing mechanism 4 is provided at the end of the main gas pipe 7 located inside the mixing cylinder 3. A continuous flame gas pipe 8 is connected to one side of the installation cylinder 1. The continuous flame gas pipe 8 passes through the installation cylinder 1 and the mixing cylinder 3 and extends into the interior of the mixing cylinder 3.
