Description

Technical Field

[0001] The utility model relates to a gas stove accessory, in particular to a bottom ignition gas stove head. Background Art

[0002] Gas stoves are common cooking equipment in home kitchens. They mainly use gas combustion to provide heat to cook food. Traditional gas stoves generally use the upper ignition method, that is, the ignition needle is set inside the ignition cover. In this structure, the ignition needle will be in a high temperature environment when the gas stove is working, and it is also easily baked by the flame during combustion. Under the baking of high temperature and flame for a long time, the ignition needle is very easy to be damaged, which in turn affects the normal use and safety of the gas stove.

[0003] In addition, the ignition needle is exposed to the external environment and is also subject to external impact. For example, when cleaning or moving the gas stove, the ignition needle is easily collided and damaged. This structural design shortens the life of the ignition needle and requires frequent replacement, which increases the user's maintenance cost and inconvenience of use. Therefore, it is necessary to make further improvements.

[0004] In order to overcome the problem that the ignition needle in the above-mentioned traditional gas stove is easily damaged, the present invention provides a lower ignition gas stove head, which effectively prevents the ignition needle from being affected by high temperature and external impact by improving the setting position and protection structure of the ignition needle, thereby improving the service life of the ignition needle and the safety of the gas stove.

[0023] The utility model is further described in detail below with reference to the accompanying drawings. A bottom ignition gas burner head includes an ejector tube 1, the ejector tube 1 is provided with a docking seat 2, and also includes an isolation plate 3, a mounting hole 4 is opened in the middle of the isolation plate 3, the docking seat 2 passes through the mounting hole 4 and protrudes from the upper end surface of the isolation plate 3, and a fire distribution cover 5 is provided with a docking hole 6 at the bottom thereof and is detachably connected to the docking seat 2;

[0024] An igniter 7 is also installed below the isolation plate 3. Corresponding to its installation position, an ignition hole 8 is opened on the isolation plate 3. The ignition hole 8 is arranged corresponding to the edge of the ignition cover 5. During ignition, the igniter 7 sprays flames toward the ignition hole 8 to ignite the ignition cover 5.

[0025] In one example: the igniter 7 is provided with a bracket 9, and the bracket 9 is fixed to the housing.

[0026] In one of the examples: the ignition hole 8 is a through hole that passes through the upper and lower end surfaces of the isolation plate 3. Corresponding to the position of the through hole, an ignition groove 10 is provided below the isolation plate 3, and the upper end of the ignition groove 10 is fixedly connected to the isolation plate 3.

[0027] In one example, the ignition groove 10 is a groove-shaped structure with an open upper end, and the groove opening of the ignition groove 10 is installed toward the isolation plate 3 .

[0028] In one embodiment, the igniter 7 is extended into the ignition groove 10 and is arranged therein.

[0029] In one example, the horizontal angle between the main body of the ignition groove 10 and the isolation plate 3 is 30-60°.

[0030] In one example, the notch of the ignition groove 10 is arranged on the back side of the ignition hole 8 covered by the ignition groove.

[0031] In one of the examples: the isolation plate 3 is further provided with a plurality of fixing holes 11 , and a plurality of fixing bolts pass through the fixing holes 11 to connect with the docking seat 2 , so as to fix the ejector tube 1 to the bottom of the isolation plate 3 .

[0032] Working principle: In this case, the ejector tube 1 is connected to the gas nozzle. When the gas is fully mixed with the air through the ejector tube 1, the mixed gas flows to the fire distribution cover 5 through the docking seat 2 in the ejector tube 1. The ejector tube 1 is connected to the fire distribution cover 5 through the docking seat 2, so that the gas can be evenly distributed to each combustion hole of the fire distribution cover 5, ensuring the uniformity and stability of gas combustion.

[0033] Furthermore, the igniter 7 in this case is arranged below the isolation plate 3, and ignites through the ignition hole 8 opened on the isolation plate 3. During ignition, the igniter 7 sprays flames toward the ignition hole 8, and the flames reach the edge of the ignition cover 5 through the ignition hole 8, igniting the gas released from the combustion hole of the ignition cover 5 to achieve ignition.

[0034] Among them, in order to make the ignition movement direction controllable and stable, the ignition hole 8 in this case is a through hole that penetrates the upper and lower end surfaces of the isolation plate 3, ensuring that the flame can smoothly pass through the isolation plate 3 to ignite the fire-dividing cover 5, and an ignition groove 10 is provided under the isolation plate 3. The ignition groove 10 cooperates with the ignition hole 8, and the upper end of the ignition groove 10 is fixedly connected to the isolation plate 3 and has a certain installation angle, so that the flame can be effectively guided to the fire-dividing cover 5.

[0035] Compared with the conventional technology: the igniter 7 in this case is arranged below the isolation plate 3, which avoids direct baking by high temperature flames, significantly reduces damage to the ignition needle caused by high temperature, and prolongs the service life of the ignition needle. In addition, the igniter 7 is protected by the isolation plate 3, which avoids direct impact from the external environment, and improves the durability and reliability of the ignition needle.

[0036] The design of the isolation plate 3 and the ignition groove 10 effectively protects the igniter 7 from being damaged during use, thereby enhancing the safety and stability of the ignition system. The matching design of the ignition hole 8 and the ignition groove 10 ensures that the flame ejected by the igniter 7 can accurately ignite the ignition cover 5, thereby improving the ignition success rate and reducing the risk of ignition failure.

[0037] In summary, the present invention significantly improves the safety, reliability and service life of the gas burner head through the innovative ignition needle protection structure and ignition system design, and exhibits excellent technical advantages in ignition efficiency, structural stability and maintenance convenience. It has significant progress and strong market competitiveness, and can therefore be widely promoted and used.

[0038] In summary, the present invention significantly improves the safety, reliability and service life of the gas furnace through the innovative design of the ignition needle position and protection structure, and exhibits excellent technical advantages in ignition efficiency, maintenance convenience and adaptability, and has significant practical value and market competitiveness.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
