However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.
[0027] The terms “a,” “one,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “include” and “have” are used to indicate an open-ended meaning of inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.
[0028] This utility model embodiment provides a flame cap, such as Figure 1-8 As shown, the burner cap includes an outer ring wall 100, on which a main burner hole group 1, a flame stabilizing hole group 2, a pressure stabilizing groove 3, and a pressure relief hole group 4 are provided. The main burner hole group 1 includes a plurality of evenly arranged main burner holes 11. The flame stabilizing hole group 2 is located below the main burner hole group 1 and includes a plurality of evenly arranged flame stabilizing holes 21. The pressure stabilizing groove 3 is located below the flame stabilizing hole group 2. The pressure relief hole group 4 includes a first pressure relief hole 41 corresponding to each main burner hole 11. Each first pressure relief hole 41 is simultaneously connected to the corresponding main burner hole 11, the pressure stabilizing groove 3, and the external environment. Part of the gas in the main burner hole 11 enters the corresponding first pressure relief hole 41, and at least a portion of the gas flowing out of the first pressure relief hole 41 can enter the pressure stabilizing groove 3. Figure 1-5The flame stabilizing orifice 21 shown serves the same function as in the prior art, reducing the flow velocity in the main flame region, enabling the burner to maintain stable combustion over a wider range of gas pressure and flow velocity, thus improving combustion efficiency. Furthermore, this application also includes two pressure relief paths. The first pressure relief path involves a first pressure relief orifice 41 on each main flame orifice 11. Part of the gas in the main flame orifice 11 enters the first pressure relief orifice 41, slowing the flow velocity and achieving a flame stabilizing effect, thereby achieving the first pressure relief of the main flame orifice 11. The second pressure relief path involves connecting the first pressure relief orifice 41 to the pressure stabilizing tank 3. The gas delivered by the first pressure relief orifice 41 can enter the pressure stabilizing tank 3, either entirely or partially, and finally enter the external environment. Since the flow from the first pressure relief orifice 41 to the pressure stabilizing tank 3 is a process from a small space to a large space, the gas flowing out of the first pressure relief orifice 41 will have its flow velocity reduced again after entering the pressure stabilizing tank 3, achieving a second pressure relief. Finally, the airflow entering the pressure stabilizing tank 3 will flow to the outer surface of the burner cap at a lower speed, thereby stabilizing the main flame orifice 11. In other words, this application, based on the flame stabilization achieved by the flame stabilization hole 21, adds a first pressure relief hole 41, so that the pressure of part of the main flame hole 11 is relieved again by the first pressure relief hole 41 and the pressure stabilizing groove 3, thereby strengthening the pressure relief and flame stabilization effect, improving the flame stabilization effect of the main flame hole 11, thus meeting the requirements of ultra-high efficiency burners, solving the balance problem between the flame stabilization effect and the flame hole area ratio of the flame stabilization hole 21, improving the heat intensity of the flame hole, achieving effective flame stabilization, enhancing the heat exchange intensity between the flame and the bottom of the pot, and improving thermal efficiency.
[0029] In a preferred embodiment of this invention, each first pressure relief hole 41 extends radially along and penetrates the outer annular wall 100. The air inlet of the first pressure relief hole 41 is connected to its corresponding main flame hole 11. The hole wall of the first pressure relief hole 41 intersects with the wall of the pressure stabilizing groove 3. The hole wall of the first pressure relief hole 41 has an outlet communicating with the pressure stabilizing groove 3, so that the middle part of the first pressure relief hole 41 communicates with the pressure stabilizing groove 3. Part of the gas in the main flame hole 11 enters the first pressure relief hole 41, and all the gas delivered by the first pressure relief hole 41 enters the pressure stabilizing groove 3, and finally enters the external environment. The entire process is a process from a small space to a large space, and after multiple pressure reliefs, the pressure relief and flame stabilization effects are effectively enhanced.
[0030] Optionally, the structure of the first pressure relief hole 41 in this application can also be configured such that part of the gas inside the first pressure relief hole 41 directly enters the external environment, while the other part enters the external environment after passing through the pressure stabilizing groove 3. Specifically, each first pressure relief hole 41 extends axially along and through the outer ring wall 100. The inlet end of the first pressure relief hole 41 is connected to its corresponding main burner hole 11, and the outlet end is connected to the external environment. The hole wall of the first pressure relief hole 41 intersects with the groove wall of the pressure stabilizing groove 3, so that the middle part of the first pressure relief hole 41 communicates with the pressure stabilizing groove 3. In this way, the gas can flow quickly to the outside of the burner cap through two paths: the first path is that part of the gas inside the first pressure relief hole 41 enters the pressure stabilizing groove 3 and then enters the external environment; the second path is that the other part of the gas inside the first pressure relief hole 41 directly enters the external environment. However, when the pressure inside the first pressure relief hole 41 is low, the pressure is mainly relieved through the first path; when the gas pressure inside the first pressure relief hole 41 is high, the flow rate is large and the flow velocity is fast, the two paths can work simultaneously to achieve better pressure relief and meet the pressure relief requirements under different firepower.
[0031] In a preferred embodiment of this utility model, such as Figure 1-7 As shown, the flame stabilizing hole 21 has a through hole 22 connecting to the pressure stabilizing groove 3. Specifically, in this application, the wall of the flame stabilizing hole 21 intersects with one wall of the pressure stabilizing groove 3. During the manufacturing process of the burner cap, the flame stabilizing hole 21 is first opened on the burner cap, and then the pressure stabilizing groove 3 is opened on the outer periphery of the burner cap. This process cuts through the flame stabilizing hole 21 and forms a through hole 22 connecting to the pressure stabilizing groove 3 in the flame stabilizing hole 21. In this way, some of the gas in the flame stabilizing hole 21 can flow out from the through hole 22 and into the pressure stabilizing groove 3, and then flow into the external environment from the pressure stabilizing groove 3, thereby slowing down the flow rate of the flame stabilizing hole 21 and the through hole 22, thus playing a role in stabilizing the flame. In this way, through the first pressure relief from the main burner hole 11 to the first pressure relief hole 41, the second pressure relief from the first pressure relief hole 41 to the pressure stabilizing groove 3, and the third pressure relief from the flame stabilizing hole 21 and the through hole 22, the pressure relief effect can be effectively strengthened, the flame stabilizing effect of the main burner hole 11 can be improved, the heat exchange intensity between the flame and the bottom of the pot can be enhanced, and the thermal efficiency can be improved.
[0032] In a preferred embodiment of this utility model, such as Figure 1-7As shown, the area ratio of the first pressure relief hole 41 to the main flame hole 11 is 23% to 24%. In this application, not only is a large proportion of the main flame hole 11 ensured, but flame stabilization is also achieved, thereby increasing the effective heat of heating the pot bottom, increasing the heat intensity of the flame holes, enhancing the impact of the flame on the pot bottom, and strengthening heat exchange. Furthermore, this application compares the thermal efficiency of this application with a burner containing only the main flame hole group 1 and the pressure stabilizing hole group 2, by adding a pressure relief hole group 4 to the main flame hole group 1 and the pressure stabilizing hole group 2. A comparison of multiple groups with different main flame hole outlet areas reveals that the highest thermal efficiency of existing burners is 77.6%, while the thermal efficiency of this application reaches 78.5%. In other words, this application can achieve greater flame hole heat intensity while ensuring flame stabilization, thereby increasing the heat exchange intensity between the flame and the pot bottom and improving the thermal efficiency of the burner.
[0033] In a preferred embodiment of this utility model, such as Figure 1-7 The flame cover shown also includes an inner ring wall 200 and a top wall 300. The inner ring wall 200 is located on the inner circumference of the outer ring wall 100. The top wall 300 connects the inner ring wall 200 and the top of the outer ring wall 100. The outer ring wall 100, inner ring wall 200, and top wall 300 together form the inner cavity 400 of the flame cover. The top wall 300 gradually slopes downwards from the outside to the inside. The sloped top wall 300 can "constrain" and "guide" the ejected combustion gas. It can guide the flame towards the bottom of the pot, allowing it to stably adhere to the edge of the flame cover and burn, effectively preventing flame lift-off. Stable adhesion and combustion also ensure a stable air supply, thereby promoting complete combustion and reducing yellow flames.
[0034] In a preferred embodiment of this utility model, such as Figure 1-7 As shown, the top wall 300 is provided with a fire-transfer groove 5, which includes a groove bottom 51, two first groove walls 52, and a second groove wall 53. The groove bottom 51 is inserted below the top wall 300 and connected between the outer ring wall 100 and the inner ring wall 200. The bottoms of the two first groove walls 52 are respectively connected to the groove bottom 51, and the outer sides of the tops of the two first groove walls 52 are respectively connected to the outer periphery of the top wall 300, while the inner sides of their tops pass through the top wall 300. The second groove wall 53 is connected to the inner sides of the tops of the two first groove walls 52, and the second groove wall 53 is inclined downwards from the outside to the inside. Figure 1-2 It is easy to see that the side of the fire-transfer groove 5 near the inner ring wall 200 protrudes from the top wall 300. This design enables rapid ignition and fire transfer, avoids blockage by overflowing liquid from the pot, maintains the unobstructed fire-transfer channel, and ensures normal ignition and use even after slight overflow, thus optimizing the fire-transfer path. Furthermore, the downward-sloping second groove wall 53 from the outside inwards quickly guides overflowing liquid from the pot to the outside of the burner cap, preventing it from affecting the fire-transfer groove 5 and maintaining the unobstructed fire-transfer channel.
[0035] In a preferred embodiment of this utility model, such as Figure 1-7As shown, the second groove wall 53 has a second through hole 511 that connects to the inner cavity 400 of the flame cover. Since the flame transfer groove 5 is relatively large, it is prone to flame detachment. By setting the second through hole 511, the flame transfer groove 5 can be prevented from detaching from the flame, thus playing a role in stabilizing the flame.
[0036] In a preferred embodiment of this utility model, such as Figure 1-7 As shown, the bottom 51 of the trough is provided with a first through hole 531, and the fire transmission trough 5 is connected to the inner cavity 400 of the flame cap through the first through hole 531. When the fire transmission trough is connected to the inner cavity of the flame cap, the flame will instantly fill the entire inner cavity of the flame cap upon ignition. During the combustion process, if there is soup overflowing from the bottom of the pot or a strong wind, the flame that is only transmitted outside the flame cap can be easily extinguished. The fire transmission channel and flame located inside the flame cap are physically protected by the flame cap body and are not easily disturbed by the outside world.
[0037] In a preferred embodiment of this utility model, such as Figure 1-7 As shown, the top wall 300 and the outer ring wall 100 have a cut 500 at the intersection area located outside the flame transfer groove 5 to reduce the wall thickness of the flame transfer groove 5 at the connection between the top wall 300 and the outer ring wall 100. Since the wall thickness at this location on the outer side 1 of the outer flame cap is generally thicker than at other locations, in order to ensure that the flame in the flame transfer groove 5 can be transmitted from the inside to the outside, it is necessary to ensure that there is flame throughout the entire flame transfer groove 5. By setting the cut 500, the wall thickness at the connection between the top wall 300 and the outer ring wall 100 can be reduced, the gas resistance can be reduced, the gas output of the flame transfer groove 5 can be increased, and the flame can be quickly and evenly transmitted to the entire flame cap.
[0038] In a preferred embodiment of this utility model, such as Figure 1 , 2 As shown in Figure 4, the burner cap is also equipped with a pot support, and the pressure relief hole group 4 also includes a second pressure relief hole 42, which connects the inner cavity of the burner cap and the pressure stabilizing groove 3. The burner cap of this application can also be fixed with a pot support, and no main flame hole 11 is provided below the area of the burner cap corresponding to the pot support, but a flame stabilizing hole 21 and a second pressure relief hole 42 are provided. The second pressure relief hole 42 connects the inner cavity of the burner cap and the pressure stabilizing groove 3. The diameter of the second pressure relief hole 42 can be the same as the diameter of the first pressure relief hole 41. The second pressure relief hole 42 can further enhance the pressure relief of the main flame hole 11, improve the flame stabilizing effect, and solve the problem of poor flame stabilizing effect caused by the excessively large total exhaust area of multiple main flame holes 11 on combustion, especially in ultra-high-pressure burners. Furthermore, the reason why no main flame hole 11 is provided in the clearance area where the pot support is installed on the burner cap in this application is to avoid the flame of the main flame hole 11 burning the pot support, thereby suppressing flue gas generation.
