Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of gas stoves, specifically relating to a burner head with an adjustable direct injection component. Background Technology
[0002] As people's living standards continue to improve, their requirements for cooking food are also increasing. Direct-injection stoves, with their concentrated flames, strong heat, and high combustion, can meet people's needs for efficient and rapid stir-frying, and are therefore very popular.
[0003] To meet the demands of large-scale production and maintain low manufacturing costs, most mainstream stoves on the market are manufactured using a casting process. However, the casting process is susceptible to dimensional tolerances due to factors such as mold wear and the cooling rate of the molten metal. Furthermore, traditional direct-injection components are typically mounted in a fixed configuration, making it impossible to adjust their position according to the actual tolerances of the stove body. This misalignment between the gas outlet of the direct-injection component and the center of the direct-injection premixing channel causes a deviation in the gas injection trajectory. Consequently, the flame distribution produced during cooking is uneven, resulting in uneven heating around the bottom of cooking utensils and affecting the quality of the food. Moreover, to reduce casting tolerances, the manufacturing precision of the casting molds is typically optimized. Pursuing high-precision casting molds significantly increases the cost of the molds, leading to a substantial increase in the production cost of the stove body and hindering cost control for the company.
[0004] Therefore, further improvements are needed. Utility Model Content
[0005] The purpose of this utility model is to overcome at least one of the shortcomings of the prior art and to provide a burner head with an adjustable direct injection component, wherein the direct injection component is adjustablely installed on the furnace body, ensuring that the gas outlet end of the direct injection component can be aligned with the center of the direct injection premix channel.
[0006] To achieve the above objectives, the technical solution provided by this utility model embodiment is as follows:
[0007] A burner head with an adjustable direct injection component includes a furnace body and a direct injection component disposed on the furnace body. The furnace body is provided with a direct injection premixing channel, which is disposed vertically through the center of the furnace body. The direct injection component is adjustablely installed on the furnace body so that the position of the direct injection component can be adjusted horizontally to ensure that the gas outlet end of the direct injection component is aligned with the center of the direct injection premixing channel.
[0008] An adjustable mounting structure is provided between the direct injection component and the furnace body. The direct injection component can be horizontally adjusted and fixed to the furnace body through the adjustable mounting structure.
[0009] The direct injection component includes a direct injection body. The furnace body is provided with mounting columns. The mounting columns are a plurality of columns arranged on the bottom surface of the furnace body and are evenly spaced around the direct injection premix channel. The adjustable installation structure includes mounting holes on the mounting columns, adjustment holes on the direct injection body corresponding to the mounting holes, and fastening components that are fastened to the mounting holes. The mounting holes are located at the bottom end of the mounting columns, and the adjustment holes are strip-shaped and extend outward from the center of the direct injection body.
[0010] When the fastening component passes through the adjustment hole and connects with the mounting hole, the position of the direct injection component is adjusted horizontally through the adjustment hole so that the air outlet end of the direct injection component is aligned with the center of the direct injection premix channel.
[0011] When the fastening component is fastened to the mounting hole, the fastening component presses the direct injection body against the mounting column, thereby fixing the direct injection component to the furnace body.
[0012] The direct injection body is provided with an air passage, and an air inlet and an air outlet connected to the air passage. The vertical projection shape of the air passage is cross-shaped and is located inside the direct injection body. There is at least one air inlet located on the side wall of the direct injection body, and there are several air outlets evenly spaced on the top surface of the direct injection body.
[0013] The direct injection body is also provided with a hollow part, which is recessed inward from the bottom of the direct injection body and avoids the air passage.
[0014] The air inlet is two, and the direct injection component also includes an air inlet component, an air outlet component, and a plug component. The air inlet component is disposed on one of the air inlets to enable the direct injection body to communicate with an external air source, the plug component is disposed on the other air inlet to block the air inlet, and the air outlet component is disposed on the air outlet with its air outlet end facing the air inlet end of the direct injection premix channel.
[0015] When the direct injection component is installed on the furnace body, there is a certain gap between the direct injection body and the direct injection premixing channel so that air can enter the direct injection premixing channel through the gap and mix with the gas output by the direct injection component. The gap is A, 8mm≤A≤12mm.
[0016] The furnace body is provided with a fire distribution gas chamber and an ejector tube connecting the fire distribution gas chamber. The fire distribution gas chamber is annular and located around the direct injection premix channel. The ejector tube is located on the side of the furnace body. The horizontal projection shape of the air inlet end of the ejector tube is conical, and its radial dimension gradually decreases along the gas delivery direction.
[0017] The furnace body is also provided with a gas guide plate for guiding the gas to be evenly distributed in the fire distribution chamber. The gas guide plate is set on the top opening of the fire distribution chamber and is located above the gas outlet end of the ejector tube.
[0018] The burner head also includes a fire cover, which is installed on the top opening of the fire distribution chamber. The fire cover is provided with a first fire distribution hole and a second fire distribution hole. The first fire distribution hole consists of several holes and is evenly spaced on the outside of the fire cover, and the second fire distribution hole consists of several holes and is evenly spaced on the inside of the fire cover.
[0019] The burner head also includes an ignition needle, and the furnace body is provided with an ignition mounting plate for installing the ignition needle. The ignition mounting plate is located between the direct injection premix channel and the fire distribution chamber.
[0020] The beneficial effects of this utility model are as follows:
[0021] This utility model, through the adoption of the above technical solution, features a burner head with an adjustable direct injection component mounted on the burner body. This allows the direct injection component to be adjusted horizontally according to the actual tolerances of the burner body, ensuring that the gas outlet of the direct injection component is aligned with the center of the direct injection premixing channel of the burner body. This prevents misalignment between the two and ensures that the gas injection trajectory is aligned with the direct injection premixing channel. Consequently, the flame distribution generated by the burner head during cooking is uniform, resulting in even heating of the bottom and surrounding areas of the cooking vessel and guaranteeing the quality of the cooked food.
[0022] By adopting the above technical solution for the furnace head, the gas outlet of the direct injection component can be aligned with the center of the direct injection premixing channel of the furnace body by adjusting the horizontal position of the direct injection component. Therefore, the furnace body casting is allowed to have a reasonable range of dimensional tolerances, which reduces the production requirements of the furnace body casting. There is no need to excessively pursue the high precision of the casting mold, which reduces the investment cost of the casting mold and thus reduces the production cost of the furnace body, which is conducive to the enterprise's cost control of the furnace body.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0032] See Figure 1-8 This burner head, equipped with an adjustable direct injection component 2, includes a burner body 1 and a direct injection component 2. In this embodiment, the burner body 1 is provided with a direct injection premixing channel 11, which runs vertically through the center of the burner body 1. An adjustable mounting structure is provided between the direct injection component 2 and the burner body 1. The adjustable mounting structure allows the direct injection component 2 to be adjusted horizontally and fixed to the burner body 1. This allows the position of the direct injection component 2 to be adjusted horizontally according to the actual tolerance of the burner body 1, ensuring that the gas outlet of the direct injection component 2 is aligned with the center of the direct injection premixing channel 11 of the burner body 1, avoiding misalignment between the two, and ensuring that the gas injection trajectory is aligned with the direct injection premixing channel 11. This results in a uniform flame distribution during cooking, ensuring that the bottom of the cooking vessel is heated evenly around the perimeter, thus guaranteeing the quality of the cooked food.
[0033] By adopting the above technical solution for the furnace head, the gas outlet of the direct injection component 2 can be aligned with the center of the direct injection premixing channel 11 of the furnace body 1 by adjusting the horizontal position of the direct injection component 2. Therefore, the furnace body 1 casting is allowed to have a reasonable range of dimensional tolerances, which reduces the production requirements of the furnace body 1 casting. There is no need to excessively pursue the high precision of the casting mold, which reduces the investment cost of the casting mold, thereby reducing the production cost of the furnace body 1 and is conducive to the enterprise's cost control of the furnace body 1.
[0034] Furthermore, in this embodiment, the direct injection component 2 includes a direct injection body 21, and the furnace body 1 is provided with mounting columns 12. Preferably, there are three mounting columns 12, which are arranged circumferentially and evenly around the periphery of the direct injection premixing channel 11 on the bottom surface of the furnace body 1. The adjustable mounting structure includes mounting holes 121, adjusting holes 211, and fastening components 3. The mounting holes 121 are preferably screw holes, located on the mounting columns 12 and at their bottom ends. The adjusting holes 211 are strip-shaped, located on the direct injection body 21, and extend outward from the center of the direct injection body 21. The length of the adjusting holes 211 is preferably 3mm-5mm, ensuring that the direct injection component 2 can be installed smoothly. For fine-tuning of the position, the fastening component 3 is preferably a screw that is threadedly fastened to the mounting hole 121. When the fastening component 3 passes through the adjustment hole 211 and is connected to the mounting hole 121, the direct injection component 2 is moved horizontally through the adjustment hole 211 so that the air outlet end of the direct injection component 2 is aligned with the center of the direct injection premix channel 11. When the fastening component 3 is fastened to the mounting hole 121, the direct injection body 21 is pressed against the mounting column 12 through the fastening component 3, so that the direct injection component 2 is fixedly installed on the furnace body 1, preventing the direct injection component 2 from loosening during use. This ensures both the adjustability of the direct injection component 2 and the fixed installation of the direct injection component 2, which can be understood by those skilled in the art.
[0035] Furthermore, the direct injection body 21 is provided with a gas flow channel 212, an air inlet 213, and an air outlet 214. Specifically, in this embodiment, the vertical projection shape of the gas flow channel 212 is cross-shaped and is located inside the direct injection body 21, so that the gas can be evenly distributed inside the direct injection body 21. The air inlet 213 is located on the side wall of the direct injection body 21 and connects to the gas flow channel 212. The number of inlets is preferably two and they are arranged at intervals to enable external gas sources to input gas into the direct injection body 21. The dual air inlets 213 enable the direct injection body 21 to flexibly switch gas sources, allowing the furnace body 1 to simultaneously adapt to multiple fuels such as natural gas and liquefied petroleum gas. The air outlet 214 is located on the top surface of the direct injection body 21. The number of outlets is preferably five and they are evenly arranged at intervals to enable the output of gas from the direct injection body 21. The multiple outlets can increase the flame coverage area and further make the bottom of the cooking vessel more evenly heated, as those skilled in the art can understand.
[0036] Furthermore, the direct injection body 21 is also provided with a hollow portion 215. Specifically, in this embodiment, the hollow portion 215 is provided on the bottom surface of the direct injection body 21. It is recessed inward from the bottom surface of the direct injection body 21 and avoids the gas flow channel 212. While ensuring the function of the direct injection body 21, it can reduce the amount of material used in the direct injection body 21, so that the direct injection body 21 achieves a balance between lightweight and function, optimizes the structure of the direct injection body 21, reduces the production cost of the direct injection body 21, and reduces the weight of the direct injection body 21, making the burner head lighter. This is something that those skilled in the art can understand.
[0037] Furthermore, the direct injection component 2 also includes an air intake component 22, an air outlet component 23, and a plug component 24. Specifically, in this embodiment, the air intake component 22 is preferably a metal connector and is installed on one of the air inlets 213 through a threaded structure to enable the direct injection body 21 to communicate with an external air source. The plug component 24 is preferably a metal plug and is installed on the other air inlet 213 through a threaded structure to block the air inlet 213, so that the direct injection component 2 can meet the usage requirements of a single air source or dual air sources, thus improving the versatility of the direct injection component 2. The air outlet component 23 is preferably a metal nozzle and is installed on the air outlet 214 through a threaded structure, with its air outlet facing the air inlet of the direct injection premixing channel 11, so that the gas inside the direct injection component 2 is sprayed out in the direction of the direct injection premixing channel 11, which can ensure the mixing efficiency of gas and air, as can be understood by those skilled in the art.
[0038] Furthermore, in this embodiment, when the direct injection component 2 is disposed on the furnace body 1, there is a certain gap between the direct injection body 21 and the direct injection premixing channel 11. The size of the gap is preferably 9mm, so that air enters the direct injection premixing channel 11 through the gap and mixes with the gas output by the direct injection component 2. Through the above technical solution, air can be sent into the direct injection premixing channel 11 through the gap and premixed with the gas output by the direct injection body 21, ensuring the combustion effect of the gas in the direct injection body 21. This is understood by those skilled in the art.
[0039] Furthermore, the furnace body 1 is also provided with a flame distribution chamber 13 and an injector tube 14. Specifically, in this embodiment, the flame distribution chamber 13 is annular and located around the direct injection premix channel 11, and the top surface of the flame distribution chamber 13 is open. The arrangement of the flame distribution chamber 13 can increase the flame range generated by the furnace head. The injector tube 14 is located on the side of the furnace body 1 and connects to the flame distribution chamber 13. The horizontal projection shape of the air inlet end of the injector tube 14 is conical, and its radial dimension gradually decreases along the gas delivery direction. Through the above technical solutions, while the gas is delivered from the external gas source to the flame distribution chamber 13, the gas is concentrated from the outside of the injector tube 14 towards its center, which increases the gas flow rate and enhances the gas pressure, thereby outputting gas with higher flow rate and higher pressure to the flame distribution chamber 13. This is understandable to those skilled in the art.
[0040] Furthermore, the furnace body 1 is also provided with a gas guide plate 15. Specifically, in this embodiment, the gas guide plate 15 is disposed on the top opening of the fire distribution chamber 13 and located above the gas outlet end of the injector tube 14. The vertical projection shape of the gas guide plate 15 is arc-shaped and extends from the gas outlet end of the injector tube 14 to both sides. When the gas enters the fire distribution chamber 13, the gas guide plate 15 can guide the gas to various positions in the fire distribution chamber 13, so that the gas can be evenly distributed in the fire distribution chamber 13. Through the above technical solution, the turbulence of the gas in the fire distribution chamber 13 is suppressed, and the flame generated by the fire distribution chamber 13 is kept consistent, further making the bottom of the cooking vessel more evenly heated. This is understandable to those skilled in the art.
[0041] Furthermore, the burner head also includes a flame cover 4. Specifically, in this embodiment, the flame cover 4 is installed on the top opening of the fire distribution chamber 13 and is provided with a first fire distribution hole 41 and a second fire distribution hole 42. There are seventy-two first fire distribution holes 41, which are evenly spaced on the outside of the flame cover 4. When the flame cover 4 is installed on the furnace body 1, the first fire distribution holes 41 connect to the fire distribution chamber 13 and ignite to form the outer ring fire of the furnace body 1. There are sixty second fire distribution holes 42, which are evenly spaced on the inside of the flame cover 4. When the flame cover 4 is installed on the furnace body 1, the second fire distribution holes 42 all connect to the fire distribution chamber 13 and ignite to form the inner ring fire of the burner head. Through the above technical solutions, the gas can be evenly sprayed out and burned from the fire distribution chamber 13, ensuring the stability and uniformity of the flame. Moreover, the fire distribution chamber 13 forms a dual-zone fire distribution design, making the flame coverage of the burner head larger. This is understandable to those skilled in the art.
[0042] Furthermore, the burner head also includes an ignition needle 5, and an ignition mounting plate 16 is provided on the furnace body 1. Specifically, in this embodiment, the ignition mounting plate 16 is set between the direct injection premix channel 11 and the fire distribution chamber 13 by welding. The ignition needle 5 is installed on the ignition mounting plate 16 by a threaded structure, which provides a stable installation position for the ignition needle 5 and can accurately ignite the gas on the furnace body 1, thereby improving the ignition reliability and success rate of the burner head.
[0043] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. 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 without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
