Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, and more specifically to a fire cover installation and fixing structure and a gas stove. Background Art

[0002] The burner of a gas stove generally consists of a burner head (or a burner head + a gas distribution plate), an outer fire cover and a central fire cover. The inner cavity of the burner head is a gas mixing chamber, and the outer fire cover and the central fire cover are arranged above the gas mixing chamber. The outer fire cover and the central fire cover are respectively provided with a full circle of fire outlet holes. The gas in the pipeline is mixed with the air through the gas mixing chamber and then sprayed out from the fire outlet holes and burned when it encounters fire. When the installation position of the outer fire cover deviates, a matching gap will appear between the fire cover and the burner head, causing fire leakage, or even abnormal combustion such as the flame retracting into the burner head. The high temperature burning of the open flame will cause the parts to burn out, and even cause a fire, which will cause safety hazards. At present, the market has the following installation and fixing structures for the fire cover: 1. With a cylindrical positioning pin; 2. Lock the fire cover and the base with screws or threads. For example, the Chinese patent authorization announcement number CN217843860U discloses a fire cover positioning mechanism and a gas stove, which adopts a method of setting a positioning hole that matches the positioning piece on the fire cover assembly and the burner head. Since the end of the positioning piece facing the positioning hole is provided with a connecting part, and the connecting part is a sphere, the wear caused by the contact between the positioning piece and the burner head is avoided. The operator rotates the fire cover assembly on the burner head. When the positioning piece rotates to the positioning hole, the positioning and installation of the fire cover assembly are achieved, which reduces the labor intensity and improves the overall installation efficiency of the gas stove equipment. However, the disadvantage is that it may cause after-sales problems such as leakage or backfire and burning of parts due to improper installation of the fire cover by the end user. For this reason, it is necessary to further improve the existing technology. Summary of the invention

[0003] The purpose of the utility model is to solve the deficiencies of the prior art and to provide a stable and reliable fire cover with a fool-proof installation design. If the fire cover is not installed properly, the stove cannot be ignited and used.
