[0002] Gas-fired furnaces are important thermal equipment widely used in industrial production processes such as heating, smelting, and roasting. They utilize the combustion of gas to generate heat energy. Through the combustion of gas mixed with air, the chemical energy in the fuel is converted into heat energy, providing the high-temperature heat source required for industrial production. Such equipment typically consists of a gas burner, furnace, waste heat recovery device, and flue gas exhaust device, and is equipped with various monitoring instruments and control systems to ensure its efficient and stable operation.
[0003] Secondly, industrial gas furnaces have many advantages, such as uniform furnace temperature, uniform workpiece heating, large loading capacity, high productivity, good furnace body insulation performance, and energy saving. These advantages make industrial gas furnaces play an important role in heat treatment processes such as metal heating, casting annealing, tempering, and quenching. At the same time, industrial gas furnaces are also equipped with complete safety protection devices, such as natural gas pressure automatic control systems and alarm systems, to ensure the safe operation of the equipment. Users can choose different types of industrial gas furnaces, such as trolley type, box type, pit type, and continuous type, according to their own products and production needs.
[0004] However, due to the design differences of different gas furnaces, there are often different distances between their reserved openings and the burner head, which places extremely high demands on the adaptability and flexibility of the ignition system; therefore, an automatic ignition device for gas furnaces is proposed to address the above problems.

[0013] The advantages of this utility model are:
[0014] 1. The automatic ignition device for a gas stove described in this utility model involves placing an installation plate in the reserved opening of the gas stove. The rotating handle, through the cooperation of the rotating rod and the threaded rod, drives the threaded sleeve to move longitudinally under the rotational limiting guidance of the limiting rod and the limiting sleeve.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1-4As shown, an automatic ignition device for a gas stove includes a mounting plate 101; a handle 102 is fixedly connected to the lower end of the mounting plate 101; limit rods 103 are symmetrically fixedly connected to the upper end of the mounting plate 101; limit sleeves 104 are slidably connected to the outer side of the limit rods 103; threaded sleeves 105 are fixedly connected between the two limit sleeves 104; a rotating rod 107 is rotatably connected to the inner side of the handle 102; a threaded rod 108 is fixedly connected to the upper end of the rotating rod 107; the threaded rod 108 is threadedly connected to the threaded sleeve 105; a handle 106 is fixedly connected to the lower end of the rotating rod 107; a heating rod 109 is fixedly connected to the upper end of the threaded sleeve 105; during operation, the mounting plate 101 is placed in the reserved opening of the gas stove, and then the handle 106 is rotated, which drives the rotating rod 107 and the threaded rod 108 to rotate, thereby igniting the gas stove through the threaded sleeve 105. The design of the rod 108 and the threaded sleeve 105, with the threaded sleeve 105 rotated and limited by the limiting rod 103 and the limiting sleeve 104, allows the threaded sleeve 105 to move longitudinally. This, in turn, drives the heating rod 109 to move longitudinally, bringing it to the side of the burner head in the gas furnace. The gas furnace is then ignited by starting the heating rod 109. In this step, the mounting plate 101 is placed in the reserved opening of the gas furnace. The rotating handle 106, through the cooperation of the rotating rod 107 and the threaded rod 108, drives the threaded sleeve 105 to move longitudinally under the rotational limiting guidance of the limiting rod 103 and the limiting sleeve 104. This allows the heating rod 109 to adjust longitudinally according to the different distances between the reserved opening and the burner head, thus optimizing the ignition connection between the reserved opening and the burner head, and improving the accuracy and efficiency of ignition.
[0024] like Figure 1-4 As shown, a serrated cylinder 201 is fixedly connected to the outer side of the handle 106; during operation, the serrated cylinder 201 increases the friction between the device and the operator's hand, making it more convenient for the operator to rotate the device.
[0025] like Figure 1-4 As shown, a fixed ring 301 is fixedly connected to the outer side of the grip 102 and the lower end of the mounting plate 101; a movable ring 302 is slidably connected to the outer side of the grip 102 and the lower end of the fixed ring 301; an internal toothed ring 303 is fixedly connected to the lower end of the movable ring 302; a spring 304 is provided between the fixed ring 301 and the movable ring 302; the two ends of the spring 304 are fixedly connected to the fixed ring 301 and the movable ring 302 respectively.
[0026] like Figure 1-4As shown, multiple fixing blocks 401 are fixedly connected to the outer side of the fixing ring 301; a fixing rod 402 is fixedly connected to the lower end of the fixing block 401; a sliding sleeve 403 is fixedly connected to the outer side of the moving ring 302; the fixing rod 402 and the sliding sleeve 403 are slidably connected; the internal toothed ring 303 is slidably engaged with the serrated cylinder 201; during operation, after the heating rod 109 is adjusted by rotating the handle 106, the elasticity of the spring 304, along with the limiting effect of the fixing rod 402 and the sliding sleeve 403 on the moving ring 302, causes the moving ring 302 to drive the internal toothed ring 303 to move downwards, thereby causing the internal toothed ring 303 to engage with the serrated cylinder 201, thus limiting the automatic rotation of the handle 106 under non-human conditions and enhancing the stability of the device.
[0027] like Figure 2-4 As shown, a limiting ring 501 is fixedly connected to the upper end of the grip 106; a limiting groove 502 is formed on the inner side of the lower end of the grip bar 102; the limiting ring 501 is located inside the limiting groove 502 and is rotatably connected to the limiting groove 502; during operation, the structural design of the limiting ring 501 and the limiting groove 502 makes the grip 106 more stable when rotating.
[0028] like Figure 1-4 As shown, the mounting plate 101 has multiple threaded holes 601 on its inner side; during operation, the threaded holes 601 make the device more stable when installed in the reserved opening.
[0029] like Figure 1-4 As shown, a silicone sleeve 701 is fixedly connected to the outer side of the rotating rod 107; during operation, the silicone sleeve 701 makes it more comfortable for the operator to hold the device.
[0030] The working principle is as follows: The mounting plate 101 is placed in the pre-reserved opening of the gas furnace. Then, the handle 106 is rotated, causing the rotating rod 107 and threaded rod 108 to rotate. Through the cooperation between the threaded rod 108 and the threaded sleeve 105, and the rotational limitation of the threaded sleeve 105 by the limiting rod 103 and the limiting sleeve 104, the threaded sleeve 105 moves longitudinally. This, in turn, drives the heating rod 109 to move longitudinally, bringing it to the vicinity of the burner head in the gas furnace. The heating rod 109 is then activated, igniting the gas furnace. In this step, the mounting plate 101 is placed in the pre-reserved opening of the gas furnace. Rotating the handle 106, through the cooperation of the rotating rod 107 and the threaded rod 108, drives the threaded sleeve 105 to move longitudinally under the rotational limitation guidance of the limiting rod 103 and the limiting sleeve 104. This allows the heating rod 109 to adjust its position according to the different distances between the pre-reserved opening of the gas furnace and the burner head. The longitudinal adjustment optimizes the ignition connection between the reserved port and the burner head, thereby improving the accuracy and efficiency of ignition. The serrated cylinder 201 increases the friction between the device and the operator's hand, making it easier for the operator to rotate the device. After adjusting the heating rod 109 by rotating the handle 106, the elasticity of the spring 304, along with the limiting of the moving ring 302 by the fixed rod 402 and the sliding sleeve 403, causes the moving ring 302 to drive the inner toothed ring 303 to move downwards. This causes the inner toothed ring 303 to engage with the serrated cylinder 201, thus limiting the automatic rotation of the handle 106 under non-human operation and enhancing the stability of the device. The structural design of the limiting ring 501 and the limiting groove 502 makes the rotation of the handle 106 more stable. The threaded hole 601 makes the device more stable when installed in the reserved port. The silicone sleeve 701 makes it more comfortable for the operator to hold the device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
