[0031] The furnace base 10 is provided with a gas supply boss 11; the nozzle 30 is installed on the gas supply boss 11; the gas supply boss 11 can be aligned and matched with the positioning notch 24.

[0032] In the present utility model, an annular retaining wall 23 is formed by extending downward at the outer edge of the gas distribution plate 20, and an air inlet end aligned with the air inlet end of the central injection channel 22 is formed in the annular retaining wall 23; the furnace base 10 is provided with a gas supply boss 11, the nozzle 30 is installed on the gas supply boss 11, and the gas supply boss 11 can be aligned and matched with the positioning notch 24. In the present utility model, by using the matching structure of the gas supply boss 11 and the positioning notch 24 of the annular retaining wall 23, the gas distribution plate 20 can be quickly aligned and installed on the furnace base 10, achieving the effect of anti-fool positioning and installation; moreover, the coherent matching structure of the annular retaining wall 23 and the gas supply boss can block the nozzle 30 and the central injection channel 22, making the appearance of the burner more beautiful and coordinated.

[0033] In this embodiment, the gas supply boss 11 is provided with an arc-shaped outer wall 12; the arc-shaped outer wall 12 is embedded in the positioning notch 24 and is in smooth transition with the annular retaining wall 23. The arc-shaped outer wall 12 and the annular retaining wall 23 form a complete and coherent circular outer wall, with a beautiful overall appearance transition and high consistency.

[0034] In this embodiment, a central first limiting portion 25 is arranged below the middle of the gas distribution plate 20; the furnace base 10 is provided with a central second limiting portion 13; the central first limiting portion 25 is matched with the central second limiting portion 13. Through the central first limiting portion 25 and the central second limiting portion 13, the middle positioning and matching of the gas distribution plate 20 and the furnace base 10 are realized. With the peripheral positioning notch 24 and the gas supply boss 11, the quick alignment and positioning installation of central alignment and circumferential alignment can be completed.

[0035] Specifically, the central first limiting portion 25 and the central second limiting portion 13 are a conical platform and a circular groove structure that cooperate with each other. The conical platform and the circular groove are centered and aligned, and the central alignment installation can be quickly carried out.

[0036] Furthermore, in order to reduce the overall weight, the conical platform structure can adopt a hollow structure.

[0037] In this embodiment, the annular gas mixing groove 21 includes two spiral bottom surfaces 26 symmetrically arranged on both sides of the central injection channel 14; the starting point of the spiral bottom surface 26 is arranged near the gas outlet end of the central injection channel 22. The cross-sectional area of the annular gas mixing groove 21 gradually decreases, and the transition of the mixed gas of fuel gas and air passing through is smooth.
