Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, and in particular to a gas stove head side ignition device. Background Technology

[0002] Commercial stoves are widely used in hotels, restaurants, canteens, and other similar establishments. Existing commercial stoves typically employ a bottom-ignition structure, where the ignition pipe and ignition mechanism are located at the center or side of the bottom of the stove. In actual use, this ignition structure is constantly at high temperatures, but liquids or water can easily fall into the stove and come into contact with it. This causes the ignition mechanism to cool down rapidly, potentially leading to the bursting of internal components like the ignition needle, shortening its lifespan. In some cases, water accumulation in the stove can also cause the ignition mechanism to malfunction.

[0003] Therefore, a Chinese utility model patent with authorization announcement number CN221279509U disclosed an independent side-ignition device. By placing the induction needle, ignition needle, and ignition tube on the side of the combustion chamber, it prevents the induction needle and ignition needle from being directly burned during use. At the same time, the ignition cover prevents soup or water from falling into and directly contacting the induction needle and ignition needle, thereby preventing the induction needle and ignition needle from bursting, improving service life, and also preventing the induction needle and ignition needle from malfunctioning due to water accumulation. The guide cover has an opening on one side, which corresponds to the induction needle and ignition needle. The vent is used to output the mixed gas, so that the mixed gas first contacts the guide cover and is output towards the induction needle and ignition needle through the guide cover. However, this requires a special induction needle, which increases the difficulty of manufacturing and increases the manufacturing cost. More importantly, the vent alone is sometimes not enough to meet the long-term burning of the permanent flame, and it is easy to go out, resulting in failure to function properly. Based on this phenomenon, it is necessary to improve the existing technology. Utility Model Content

[0017] (III) The technical effects to be achieved

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Firstly, the ignition mechanism of this utility model includes a base set on the outer wall of the burner head, and an ignition needle and a pilot flame gas pipe running through the base. The pilot flame gas pipe is connected to the main air inlet pipe, and the outlet of the pilot flame gas pipe is aligned with the ignition needle. The base is provided with a ventilation pipe connected to the combustion chamber. Through the ventilation pipe, the mixed gas (oxygen and fuel gas) in the combustion chamber can be replenished to the ignition needle area.

[0020] Secondly, the ventilation pipe of this utility model includes an air inlet on the side wall of the combustion chamber inside the burner head and an air outlet on the upper surface of the base. The air inlet and the air outlet are connected by a gas supply pipe. This ventilation pipe is reasonably designed, which facilitates the supply of the mixed gas (fuel gas and oxygen) in the combustion chamber to the ignition needle area. It is more conducive to the ignition needle to replenish the mixed gas, and it is easier for the pilot flame to be extinguished, which is more conducive to meeting the usage requirements.

[0021] Thirdly, the base of this utility model is provided with a windproof cover for covering the ignition needle and the pilot flame gas pipeline. The windproof cover corresponding to the combustion chamber is open. The windproof cover and the upper surface of the base form a pilot flame combustion chamber. The outlet of the ventilation pipe is located in the pilot flame combustion chamber. This arrangement of the windproof cover is beneficial to the space, which is conducive to the gas transported by the pilot flame gas pipeline being ignited by the ignition needle. At the same time, it is also conducive to the secondary replenishment of gas by the ventilation pipe so that the pilot flame is not easily extinguished. It is more conducive to meeting the needs of use and has great market value. Attached Figure Description

However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0036] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A side-mounted ignition device for a gas burner includes a burner head 1 and a combustion chamber 2 disposed within the burner head 1. An ignition mechanism 3 is disposed on the end face of the burner head 1 on one side of the combustion chamber 2, and a main air intake pipe 4 is disposed on the lower end face of the burner head 1. The ignition mechanism 3 includes a base 31 disposed on the outer wall of the burner head 1, and an ignition needle 32 and a pilot flame gas pipe 33 disposed along the base 31. The pilot flame gas pipe 33 is connected to the main air intake pipe 4, and the outlet of the pilot flame gas pipe 33 is aligned with the ignition needle 32. A ventilation pipe 34 is disposed on the base 31 and is connected to the combustion chamber 2. The ventilation pipe 34 can ignite the mixed gas (oxygen and fuel gas) in the combustion chamber 2 at the ignition needle 32. The ventilation pipe 34 can also replenish the mixed gas (oxygen and fuel gas) in the combustion chamber 2 to the area of ​​the ignition needle 32. This helps to achieve a longer-term combustion of the pilot flame, reduces the occurrence of extinguishing, and is more conducive to normal use.

[0037] Example 2: This can be explained based on Example 1, such as... Figure 2 , Figure 4 and Figure 5As shown, the ventilation pipe 34 includes an air inlet 341 located on the side wall of the combustion chamber 2 inside the burner head 1 and an air outlet 342 located on the upper surface of the base body 31. The air inlet 341 and the air outlet 342 are connected by a gas supply pipe. This facilitates the secondary replenishment of the mixed gas (oxygen and fuel gas) in the combustion chamber 2 to the ignition needle 32, which better meets the usage requirements. In this embodiment, there is only one ventilation pipe 34, which reduces the difficulty of manufacturing. The number of ventilation pipes 34 can be determined according to the actual situation.

[0038] Example 3: This can be described based on Example 1 or Example 2, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, to ensure better combustion of the ignition mechanism 3, a windproof cover 35 is provided on the base 31 to cover the ignition needle 32 and the pilot flame gas pipe 33. The windproof cover 35 corresponding to the combustion chamber 2 is open, and the windproof cover 35 and the upper surface of the base 31 form a pilot flame combustion chamber. The outlet of the ventilation pipe 34 is located in the pilot flame combustion chamber. This arrangement facilitates observation of the ignition of the ignition needle 32 and the combustion status, making it easier to control. Further explanation is provided below. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the base 31 is provided with a slot 311, such as Figure 7 and Figure 8 As shown, a locking block 351 that mates with the locking slot 311 is provided on the windproof cover 35, such as... Figure 3 , Figure 5 and Figure 6 As shown, the windproof cover 35 is installed on the base 31 by the cooperation of the card block 351 and the card slot 311, which also makes it easy to remove the windproof cover 35 from the base 31.

[0039] Example 4: This can be described based on Example 1, Example 2, or Example 3, such as... Figure 1 , Figure 2 and Figure 4 As shown, the outlet of the pilot flame gas pipeline 33 is equipped with a guide cover 331, which is more conducive to gas output. The main intake pipe 4 is equipped with a gas inlet 41 and a pilot flame mixed gas outlet pipe 42. The pilot flame mixed gas outlet pipe 42 is connected to the pilot flame gas pipeline 33 through a connecting pipe (not shown in the figure), which is conducive to transmitting the mixed gas (oxygen and gas) in the main intake pipe 4 to the ignition needle 32 for ignition and combustion. The gas inlet 41 is conducive to supplying gas to the main intake pipe 4.

[0040] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, as shown in the figure. Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, the burner head 1 includes a furnace body 11 and a chamber 12 disposed on the furnace body 11. A combustion seat 13 is disposed in the chamber 12, and a combustion chamber 2 is disposed inside the combustion seat 13. There is a gap between the combustion seat 13 and the furnace body 11 (a gap is formed between the outer wall of the combustion seat 13 and the inner wall of the furnace body 11, which forms a gas exhaust channel). The side walls of the combustion seat 13 are respectively provided with exhaust ports 14. The lower end face of the furnace body 11 is provided with a gas inlet 15 connected to the main air inlet pipe 4. A ventilation pipe 34 is provided on the furnace body 11. The gas (oxygen and gas) in the main air inlet pipe 4 is transported to the gap through the gas inlet 15. The gap is then transported to the combustion chamber 2 through the exhaust port 14 for combustion. At the same time, it is beneficial to replenish the gas in the gap to the ignition needle 32 area, which is conducive to achieving a longer-term combustion of the pilot flame, reducing the occurrence of extinguishing, and better meeting normal use requirements. In this embodiment, the combustion seat 13 is frustum-shaped, which is reasonable and easy to implement.

[0041] Among them, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 9 As shown, an annular lower step 121 is provided at the lower part of the furnace body 11 inside the chamber 12, and an upper step 122 is provided at the opening of the furnace body 11 in the chamber 12. Gas inlets 15 are evenly arranged along the annular lower step 121. The diameter of the lower end face of the combustion seat 13 is smaller than the inner diameter of the annular lower step 121, which is conducive to the lower part of the combustion seat 13 being inserted into the annular lower step 121. An outer edge 131 is provided on the upper end face of the combustion seat 13, and the upper step 122 is used to place the outer edge 131, which is conducive to the installation of the combustion seat 13 in the chamber 12.

[0042] Among them, such as Figure 1 , Figure 2 , Figure 5 and Figure 9 As shown, the exhaust port 14 array is arranged on the side wall of the combustion seat 13, which is conducive to the full delivery of gas.

[0043] Among them, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the base 31 and the burner head 1 are integrally formed, which greatly enhances the structural strength and makes it more conducive to the gas transmission through the ventilation pipe 34.

[0044] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as ignition needles that are mature in the existing technology, and will not be described in detail here.

[0045] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
