Description

Technical Field

[0001] This utility model relates to the field of stove head technology, specifically a stove head for commercial oil-fired clay pot stoves. Background Technology

[0002] Currently, commercial fuel-fired clay pot stoves are commonly used cooking equipment in the catering industry, mainly for cooking methods that require slow simmering over low heat, such as making soup and porridge.

[0003] In existing technologies, traditional fuel-fired stoves often suffer from intense combustion due to fuel oil splashing during actual use. This makes it difficult to maintain a stable, continuous heat, which can lead to overflowing soups or localized overheating and burning of food, affecting the cooking results. Furthermore, the heat control is not precise enough to meet the specific temperature requirements of different ingredients at different cooking stages. Therefore, this invention proposes a dedicated stove head for commercial fuel-fired clay pot stoves to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing oil-fired stoves, such as inaccurate flame adjustment and excessive splattering leading to intense flames, this invention incorporates a relatively rotatable upper and lower flame retardant, along with specially sized flame outlets and spiral guide channels. This achieves precise control of the flame jet and the transition from intense to gentle heat, preventing spillage of broth and burning of food, thus improving both cooking results and safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a burner head base, the burner head base end face is provided with a placement cavity, the burner head base end face is integrally formed with an ignition cover, the placement cavity is provided with an upper retarder, a lower retarder and a distributor, the distributor is installed at the bottom of the placement cavity, a gas pipe is installed on the outer wall of the burner head base, and one end of the gas pipe is connected to the inside of the distributor, the lower retarder is placed on the end face of the distributor, the upper retarder is fastened above the lower retarder, the outer walls of the upper and lower retarders are respectively provided with two fire outlet holes and one fire outlet hole on their circumference, the two fire outlet holes and the one fire outlet hole are staggered, the bottom of the lower retarder is provided with multiple sets of fire inlet holes, a rotating mechanism is installed inside the ignition cover, and the outer walls of the upper and lower retarders are both cover-shaped, with an annular flange integrally formed on the fitting side surface;

[0006] The rotating mechanism is used to drive the upper retarder to rotate relative to the lower retarder.

[0007] Preferably, the rotating mechanism includes an annular gear disk with an external tooth structure fixedly connected to the outer wall of the upper igniter, and a rotating groove is provided inside the ignition cover, and a gear is rotatably connected in the rotating groove, the gear meshing with the external teeth of the annular gear disk.

[0008] Preferably, each group of fire inlets has a spiral guide groove on its inner wall, the first fire outlet has a gradually narrowing diameter, and the second fire outlet has a gradually expanding diameter.

[0009] Preferably, the lower retarder end face is provided with an annular groove, and the upper retarder and the lower retarder contact surface are provided with a limiting plate, and the shape of the limiting plate matches the shape of the inner wall of the annular groove, and slides in the annular groove.

[0010] Preferably, an annular oil storage groove is formed on the surface of the limiting plate.

[0011] Compared with the prior art, this utility model provides a special burner head for commercial oil-fired clay pot stoves, which has the following beneficial effects:

[0012] 1. Through the meshing transmission of gears and ring gear disc, the upper retarder is driven to rotate relative to the lower retarder, dynamically adjusting the overlap area of ​​flame outlet one and flame outlet two, thereby achieving precise control of the flame spray volume. Compared with traditional burners, this burner can stably output the low heat required for slow simmering, effectively preventing the soup from boiling over or the food from overheating and burning locally, significantly improving the cooking quality of soup and porridge.

[0013] 2. The spiral guide groove on the inner wall of the ignition inlet in this device promotes full mixing of fuel and air. Combined with the structural design of the gradually narrowing ignition outlet one and the gradually expanding ignition outlet two, the intense flame is transformed into a uniform and stable smoldering flame. At the same time, the cooperation between the annular slide and the limiting plate ensures the rotational stability of the upper retarder. The annular oil storage groove on the surface of the limiting plate forms an oil seal layer, which reduces rotational friction and prevents flame leakage. Attached Figure Description

[0020] This utility model provides a technical solution for a dedicated burner head for commercial oil-fired clay pot stoves:

[0021] Please see Figure 1-4 A special burner head for a commercial oil-fired clay pot stove includes a burner head base 1. The burner head base 1 has a placement cavity on its end face. An ignition cover 13 is integrally formed on the end face of the burner head base 1. An upper igniter 4, a lower igniter 5, and a flame distributor 7 are arranged in the placement cavity. The flame distributor 7 is installed at the bottom of the placement cavity. A gas pipe 2 is installed on the outer wall of the burner head base 1, and one end of the gas pipe 2 is connected to the inside of the flame distributor 7. The lower igniter 5 is placed on the end face of the flame distributor 7. The upper igniter 4 is fastened above the lower igniter 5. The outer walls of the upper igniter 4 and the lower igniter 5 are respectively provided with a second flame outlet 12 and a first flame outlet 11 on their circumference. The second flame outlet 12 and the first flame outlet 11 are staggered. The bottom of the lower igniter 5 has multiple sets of flame inlet holes 10. A rotating mechanism is installed inside the ignition cover 13. The outer walls of the upper igniter 4 and the lower igniter 5 are both cover-shaped, and an annular flange is integrally formed on the side surface.

[0022] The rotating mechanism is used to drive the upper retarder 4 to rotate relative to the lower retarder 5.

[0023] Furthermore, by rotating the upper slower 4 and the lower slower 5 relative to each other, the overlapping area of ​​the first flame outlet 11 and the second flame outlet 12 can be dynamically adjusted, thereby precisely controlling the flame jet volume, solving the problem of inaccurate firepower adjustment of traditional stove heads, and meeting the detailed requirements of fire control in different cooking stages such as soup making and porridge making.

[0024] The rotating mechanism includes an annular gear disk 9 with an external tooth structure fixedly connected to the outer wall of the upper retarder 4. A rotating groove 14 is provided inside the ignition cover 13, and a gear 15 is rotatably connected inside the rotating groove 14. The gear 15 meshes with the external teeth of the annular gear disk 9.

[0025] Furthermore, through the meshing transmission between gear 15 and ring gear disk 9, the external adjustment force is converted into the circular motion of the upper slow burner 4. It should be noted that: before cooking, the ring gear disk 9 is driven to rotate according to the ingredients to be cooked. During the cooking process, it is forbidden to touch gear 15 to avoid burns.

[0026] Each set of fire inlets 10 has a spiral guide groove on its inner wall. Fire outlet 11 has a gradually narrowing diameter, and fire outlet 2 has a gradually expanding diameter.

[0027] Furthermore, the spiral guide groove of the fire inlet 10 causes the fuel and air to form a swirling mixture, improving combustion efficiency; the tapered fire outlet 11 accelerates the airflow injection, and the tapered fire outlet 2 12 disperses the flame. The two work together to transform the concentrated and intense fire of the traditional burner into a uniform and stable simmer, avoiding the phenomenon of soup boiling over or food being overheated and burned in some areas.

[0028] The lower retarder 5 has an annular groove 6 on its end face. The upper retarder 4 and the lower retarder 5 are fitted with a limiting plate 8. The shape of the limiting plate 8 matches the shape of the inner wall of the annular groove 6 and slides in the annular groove 6.

[0029] Furthermore, the cooperative structure between the annular groove 6 and the limiting plate 8 ensures the stability of the upper retarder 4 when it rotates.

[0030] An annular oil reservoir is formed on the surface of the limiting plate 8;

[0031] Furthermore, the annular oil reservoir can store fuel and form an oil seal layer at high temperatures, reducing the frictional resistance between the limiting plate 8 and the annular slide 6, making rotation adjustment easier.

[0032] When the operator uses the dedicated burner head of this commercial oil-fired clay pot stove, the fuel is delivered to the flame distributor 7 via the gas pipe 2, and then enters the retarder through the fire inlet 10 at the bottom of the lower retarder 5. The spiral guide grooves on the inner wall of the fire inlet 10 cause the fuel and air to swirl and mix, ensuring that the fuel and air entering the retarder are fully premixed, laying the foundation for stable combustion.

[0033] At this point, the upper retarder 4 and the lower retarder 5 are in their initial installation positions, with flame outlet 11 and flame outlet 12 staggered. In the initial state, the flame is ejected from the staggered flame outlets. Because flame outlet 11 has a tapered aperture, it accelerates the airflow, while flame outlet 12 has a widening aperture, it disperses the flame. Together, they transform the intense flame from fuel combustion into a uniform and stable simmer, avoiding the problems of soup overflowing or food burning caused by excessive heat in traditional burners.

[0034] Before cooking, the heat is adjusted according to the ingredients. The operator can drive the gear 15 inside the ignition cover 13 to rotate via an external drive structure. The gear 15 meshes with the annular gear disk 9 fixed to the outer wall of the upper retarder 4, converting the external adjustment force into the circular motion of the upper retarder 4, causing the upper retarder 4 to rotate relative to the lower retarder 5. As the upper retarder 4 rotates, the overlapping area of ​​the first flame outlet 11 and the second flame outlet 12 changes, thereby precisely controlling the flame spray volume and meeting the detailed requirements of different cooking stages such as simmering soup and making porridge, solving the problem of inaccurate heat adjustment of traditional stove heads.

[0035] The annular groove 6 on the end face of the lower retarder 5 and the limiting plate 8 on the contact surface of the upper retarder 4 ensure that the upper retarder 4 remains stable during rotation, preventing flame instability caused by shaking. At the same time, the annular oil reservoir on the surface of the limiting plate 8 stores fuel oil, forming an oil seal layer at high temperatures. This reduces the frictional resistance between the limiting plate 8 and the annular groove 6, making rotation adjustment easier and smoother, and further enhances the sealing at the contact point between the upper retarder 4 and the lower retarder 5, preventing flame leakage and improving the safety and reliability of the burner head.

[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
