Description

Technical field

[0001] The utility model relates to an installation structure of a central fire cover. [Background Technology]

[0002] Sheet metal burners are being promoted by many burner manufacturers due to their light weight, ease of processing, and low pollution levels. They are now becoming increasingly accessible to the public. Currently, the center burner caps on sheet metal burners on the market are typically riveted to the gas distributor. While this method offers good retention, the later riveting of the center burner cap to the gas distributor after production is difficult due to structural limitations inherent in the distributor, impacting assembly efficiency.

[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]

[0004] The purpose of the present invention is to overcome the above problems. We provide a mounting structure for a central fire cover, which can improve the installation efficiency of the central fire cover.

[0006] In one or more embodiments, the air inlet and the central air outlet are coaxially arranged, and the diameter of the air inlet is larger than the diameter of the central air outlet. When viewed from an upward angle, the mounting hole is located on the inner side of the air inlet.

[0007] In one or more embodiments, the screw is a slotted screw or a cross screw, the number of mounting holes is two or more, and the two or more mounting holes are evenly distributed circumferentially.

[0008] In one or more embodiments, the top center position of the gas distribution plate body is a flat plate, the central air outlet is opened in the middle of the flat plate, and the bottom of the central fire cover is a plane and fits with the flat plate.

[0009] In one or more embodiments, a central air inlet corresponding to the central air outlet is opened at the bottom of the central fire cover, the central air inlet and the central air outlet are coaxially arranged, and the diameter of the central air inlet is larger than the diameter of the central air outlet.

[0010] In one or more embodiments, the center fire cover includes an outer shell, an inner shell and a bottom plate. The bottom plate presses the inner shell inside the outer shell, and an air cavity is formed between the inner shell and the outer shell. Both the outer shell and the inner shell are provided with an air passing structure. The outer shell is riveted to the bottom plate, and the screw holes and the center air inlet are opened on the bottom plate.

[0011] Compared with the background technology, the present invention has the following effects: the center fire cover and the gas distribution plate body are fixed by screws, and the screws are installed and fixed to the center fire cover through the inside of the gas distribution plate body. The screws are not exposed and will not affect the appearance.

[0014] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0015] See attached Figure 1 The present application provides an installation structure of a central fire cover, which includes an air distribution plate main body 1 and a central fire cover 2 arranged in the middle position of the air distribution plate main body. The bottom of the air distribution plate main body is provided with an air inlet 3 at the center, and the top of the air distribution plate main body 1 is provided with a central air outlet 4 at the center. The central air outlet is connected to the interior of the central fire cover 2. The central air outlet is provided with mounting holes 5 around its edge. The central fire cover is provided with screw holes 6 at the position corresponding to the first mounting hole. The screws 7 connect the mounting holes and the screw holes to fix the central fire cover 2 to the air distribution plate main body 1. With this structure, the air distribution plate main body and the central fire cover can be produced separately, and then the air distribution plate main body and the central fire cover can be installed and fixed by screws at a later stage. Compared with riveting, it is less affected by the structure of the air distribution plate main body and has higher assembly efficiency.

[0016] See Figure 2The air inlet 3 and the central air outlet 4 are coaxially arranged, and the diameter of the air inlet is larger than that of the central air outlet. When viewed from above, the mounting hole is located inward of the air inlet. The central fire cover can be mounted and fixed by screwing screws into the bottom of the gas distribution plate body. Preferably, the screws 7 are slotted screws or Phillips screws. The number of mounting holes is two or more, and the two or more mounting holes are evenly distributed around the circumference. In this embodiment, three mounting holes are provided. Mounting and fixing with three screws provides good stability and a more solid structure after assembly.

[0017] The top center position of the gas distribution plate body 1 is a flat plate 8, the central air outlet 4 is opened in the middle position of the flat plate, the bottom of the central fire cover 2 is a plane and fits with the flat plate 8. The central fire cover and the gas distribution plate body utilize the fit of the flat surface and the flat plate to improve the sealing of the connection between the two.

[0018] The bottom of the central fire cover 2 is provided with a central air inlet 9 corresponding to the central air outlet. The central air inlet and the central air outlet are coaxially arranged, and the diameter of the central air inlet is larger than the diameter of the central air outlet, ensuring that the central air inlet does not affect the amount of gas output at the central air outlet and the gas is not blocked.

[0019] The central fire cover 2 includes an outer shell 21, an inner shell 22 and a bottom plate 23. The bottom plate presses the inner shell 22 inside the outer shell 21, and an air cavity is formed between the inner shell and the outer shell. Both the outer shell and the inner shell are provided with an air flow structure 10. The inner shell plays a role of slowing down the air, and cooperates with the air cavity to avoid explosion and backfire. The outer shell 21 is fixed to the bottom plate 23 by riveting, and the screw holes 6 and the central air inlet 9 are opened on the bottom plate.

[0020] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
