Description

Technical Field

[0001] The utility model relates to the technical field of air supply structures, in particular to an air supply structure for a barbecue grill. Background Art

[0002] Currently, barbecue grills can be divided into three categories: charcoal barbecue grills, gas barbecue grills, and electric barbecue grills. Charcoal barbecue grills produce a lot of oily smoke during the barbecue process, which pollutes the environment. At the same time, charcoal barbecue grills cannot control the heat, which can cause food to burn and pose a threat to people's health. In contrast, gas barbecue grills and electric barbecue grills are popular for their smoke-free and pollution-free performance. However, the taste of barbecue grills is not as good as that of gas barbecue grills, so more people choose gas barbecue grills. Gas barbecue grills require an air supply structure during use.

[0003] Chinese patent number CN202120858252.3 discloses a barbecue grill and its gas supply pipe assembly, comprising side burners, multiple main burners, and a temperature control valve. It also includes a three-way valve, a side burner valve connecting pipe, a main burner valve connecting pipe, and a temperature control valve connecting pipe. The side burner valve connecting pipe is connected to the side burners at one end, and to the outlet of the three-way valve at the other end. The temperature control valve connecting pipe is connected to the temperature control valve at one end, and to the outlet of the three-way valve at the other end. The main burner valve connecting pipe connects the temperature control valve and the main burners. The three-way valve inlet is also connected to a gas source. During use, the prior art suffers from poor gas and air mixing efficiency during gas supply, which affects the gas mixing efficiency. Utility Model Content
