Gas leakage during the operation can cause serious harm or even death to the human body. How to efficiently ignite and ensure that gas does not leak is a necessary condition for safe operation.

[0003] Traditional baking bags are manually ignited when in use. If one person manually ignites multiple burners, slow ignition may cause gas leakage, which poses a certain risk. At the same time, the traditional igniter has cumbersome steps during installation, making its subsequent maintenance more troublesome.

[0004] In view of this, research and improvement are carried out on the existing problems, and an external automatic igniter for a middle bag baking machine is provided, which has a reasonable structural design, high stability, and takes into account all aspects of application. The purpose is to solve the problem and improve the practical value through this technology. Summary of the invention

[0005] The present invention adopts external igniters and is arranged on one side of each burner, so that the ignition efficiency is guaranteed and damage caused by long-term baking is avoided. At the same time, a quick connection is achieved through a fixing seat and a buckle, thereby improving the convenience of later maintenance, and realizing an external automatic igniter for a middle-package baking machine.

[0006] In order to achieve the above-mentioned objectives, the present invention adopts the following technical scheme: an external automatic igniter for a middle-package baking machine, comprising a combustion hole, a high-pressure ignition needle for ignition fixedly connected to one side of the combustion hole, a self-priming air inlet for sucking in gas fixedly connected to the upper end of the combustion hole, a connecting rod for quick fixing fixedly connected to the outer side of the lower end of the combustion hole, a fixing seat for fixing fixedly connected to the lower end of the combustion hole, a fixing groove for connecting the connecting rod is provided on the inner side of the fixing seat, a sliding groove for positioning is provided on the upper end of the fixing seat, two groups of clips for fixing are movably connected to the upper end of the fixing seat, a nut for connection is fixedly connected to one side of the clip, a threaded rod is fixedly connected to the clip on the opposite side of the nut, a protrusion for positioning is fixedly connected to the lower end of the clip, and a graphene sheet for improving sealing is provided on the inner side of the clip.
