[0021] 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.

[0022] Reference Figure 1-4 The embodiment of the present invention is an ignition device for a natural gas fire grate, which includes: a shell 1, which serves as the main structure of the entire ignition device; a limiting hole is provided on the rear surface of the shell 1, which is used to limit the position of the inlet 9 of the pipe 8, ensuring that natural gas can smoothly enter the pipe 8, and the inlet 9 of the pipe 8 is located inside the limiting hole; a pipe 8 is fixedly connected to the lower bottom wall of the shell 1, which is used to introduce natural gas from the outside into the device and transport it to the nozzle for spraying; the pipe 8 is located just below the support plate 2, and an inlet 9 is provided on the rear surface of the pipe 8, which is a channel for natural gas to enter the pipe 8; a nozzle 7 is provided on the upper surface of the pipe 8, which is responsible for spraying natural gas at a certain pressure and flow rate, and meeting the electric spark generated by the spark plug to achieve ignition; a support plate 2 is movably connected to the side inner wall of the shell 1, which is used to support and fix the partition 3 to ensure the stability of the internal structure of the device; a placement platform is provided on the side inner wall of the shell 1, which is used to provide support for the support plate 2 so that it can be placed stably, and the support plate 2 is located on the upper surface of the placement platform.

[0023] The front and rear inner walls of the support plate 2 are fixedly connected with a partition 3 for separating the nozzles 7 to ensure the stability of the ignition, jet and ash collection processes. The front surface of the shell 1 is provided with a mounting hole 14 for installing the igniter. The inside of the mounting hole 14 is fixedly connected with an igniter 6 for generating high voltage electricity, generating electric sparks through the spark plug 10, and igniting the natural gas ejected from the nozzle. The rear surface of the igniter 6 is fixedly connected with a plurality of spark plugs 10 for generating electric sparks for ignition. The spark plug 10 is located directly in front of the nozzle 7, and the nozzle 7 is located between the partition 3. The front surface of the igniter 6 is provided with a switch 11 for controlling the start and stop of the igniter. The inside of the shell 1 is slidably connected with a collecting plate 4. It is used to collect ashes and solid residues generated during the combustion of natural gas. A handle is provided on the front surface of the collecting plate 4 to facilitate the user to remove and clean the collecting plate. The collecting plate 4 is located directly below the pipe 8. The lower surface of the outer shell 1 is fixedly connected with a pillar 12 to support the entire ignition device to ensure its stability. The lower end of the pillar 12 is fixedly connected with an anti-slip pad 13 to enhance the stability of the device. A placement port 5 is provided on the front surface of the outer shell 1 to place the collecting plate 4. A limiting groove is provided inside the outer shell 1 to accommodate the collecting plate 4. The limiting groove is connected to the placement port 5 to limit the sliding range of the collecting plate to prevent it from falling off or misalignment. The collecting plate 4 is located inside the limiting groove.

[0024] Working principle: When the user needs to ignite natural gas, first start the igniter 6 through the switch 11 on the front surface of the shell 1. After receiving the starting signal, the igniter 6 provides high voltage electricity to multiple spark plugs 10 through the internal circuit system. After receiving the high voltage electricity, the spark plugs 10 generate electric sparks. These electric sparks are located in front of the nozzle 7 and are used to ignite the natural gas ejected from the nozzle 7. The natural gas enters the device through the inlet 9 of the pipeline 8 and flows inside the pipeline 8 to the nozzle 7. The nozzle 7 ejects the natural gas at a certain pressure and flow rate to form a combustible gas mixture. During the ignition process, a certain amount of ash and solid residue will be generated. These ashes will naturally fall onto the collection plate 4 under the action of gravity. The collection plate 4 is located directly below the pipe 8 and can effectively capture and collect the ash to prevent it from being scattered into the environment and causing pollution. The user can use the placement port 5 on the front surface of the shell 1 and the internal limiting groove to pull out the collection plate 4 for cleaning under the action of the handle. The design of the support 12 and the anti-slip pad 13 ensures the stability of the entire ignition device, and the anti-slip pad 13 enhances the friction between the device and the installation surface to prevent the device from sliding or tipping over during operation.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
