[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0014] Please see attached Figure 1-3 The present application provides a gas burner with a fire cover positioning and water seepage prevention function, which includes a burner body 1, a central fire cover 2 and an outer ring fire cover 3. The burner body 1 is provided with a central air cavity 4 and an outer ring air cavity 5. The central fire cover 2 is covered on the central air cavity, and the outer ring fire cover 3 is covered on the outer ring air cavity. A first positioning structure is provided between the central fire cover 2 and the burner body, and the first positioning structure can limit the rotation of the central fire cover. A second positioning structure is provided between the outer ring fire cover 3 and the burner body, and the second positioning structure can limit the rotation of the outer ring fire cover. The first positioning structure is composed of a positioning pin 6 and a positioning pin 7. The center fire cover and the outer ring fire cover are composed of a socket 7, the second positioning structure is consistent with the structure of the first positioning structure, the positioning pins are arranged on the center fire cover and the outer ring fire cover, the positioning sockets are arranged on the burner body, through the cooperation of the positioning pins and the positioning sockets, after the center fire cover and the outer ring fire cover are installed to the burner body, the rotation of the center fire cover and the outer ring fire cover can be limited to keep their positions fixed; in addition, when installing the center fire cover and the outer ring fire cover, since the positioning pins and the positioning sockets need to be installed in position, the user is required to assemble them after alignment, and the user can judge whether the center fire cover and the outer ring fire cover are installed in place.
