AI Technical Summary
Existing burners are prone to blocking fire holes and difficulty in ignition in heavy oil environments. This is mainly because the bottom surface of the discharge column is covered with condensation oil stains, which makes it impossible to receive the discharge of the ignition needle normally, reducing the ignition success rate.
An ignition structure is designed, in which the lower surface of the discharge column is a spherical surface that is sunken upwardly, and the discharge end of the ignition needle is located at the center of the spherical surface. This design makes the distance between the discharge end and the bottom surface of the discharge column equal, and the oil-filled cover part will not affect the discharge, increasing the ignition success rate.
Through this design, the ignition success rate is increased because the spherical surface is partially covered without affecting the ignition success rate, and the ignition success rate is higher than that of the traditional single ignition point. In addition, the spherical surface facilitates the sliding and dripping of oil stains, reduces the accumulation of oil stains, and further improves the ignition success rate.

Description
Technical Field
[0001] The utility model relates to an ignition structure, an inner ring fire cover and a burner comprising the ignition structure. Background Art
[0002] Stir-frying and deep-frying are common cooking methods for users. Burners work in a heavy oil environment for a long time, which inevitably causes oil to accumulate and deposit. Over time, the fire hole is easily blocked and ignition is difficult. According to market maintenance feedback and simulation experiments, the discharge column on the fire cover is prone to condensed oil, which makes it impossible to receive the discharge of the ignition needle normally, resulting in a decrease in the ignition success rate. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the point on the bottom surface of the discharge column closest to the discharge end of the ignition needle is covered with condensed oil, resulting in an inability to normally receive the discharge of the discharge end, resulting in a decrease in the ignition success rate. An ignition structure, an inner ring fire cover and a burner containing the same are provided.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] An ignition structure comprises a discharge column and an ignition needle. The lower surface of the discharge column is a spherical surface that is concave upwards. The ignition needle is located below the discharge column, and the discharge end of the ignition needle is located at the center of the spherical surface.
[0006] In this scheme, the lower surface of the discharge column is set to be an upwardly concave spherical surface, the discharge end of the ignition needle is located at the center of the spherical surface, and the distance from the discharge end to any point on the bottom surface of the discharge column is equal. When the bottom surface of the discharge column is covered with oil, the discharge end can discharge to the area not covered by the oil, because the distance from the center of the sphere to each point on the spherical surface is equal, and the ignition success rate of the discharge end to the spherical surface is equal, that is, there are infinitely many discharge points, so the partial coverage of the spherical surface does not affect the ignition success rate, and the ignition success rate is higher than that of the traditional single ignition point. The upwardly concave spherical surface facilitates the oil on the bottom surface of the discharge column to slide and gather along the spherical surface to the edge of the spherical surface, and drip from the edge under the action of the oil's own gravity, thereby reducing the long-term accumulation of a large amount of oil on the lower surface of the discharge column, which reduces the ignition success rate.
[0007] Preferably, along the vertical direction, the projection of the edge of the spherical surface covers the projection of the discharge end.
[0008] In this solution, the projection of the spherical edge on the ignition needle discharge end in the vertical direction is located on the outer peripheral surface of the ignition needle discharge end, thereby ensuring that the oil stains sliding down from the spherical edge of the discharge end will not cover or block the ignition needle discharge end, ensuring that the ignition success rate will not be affected.

[0010] In this scheme, the lower surface of the discharge column is set to be an upwardly concave spherical surface, the discharge end of the ignition needle is located at the center of the spherical surface, and the distance from the discharge end to any point on the bottom surface of the discharge column is equal. When the bottom surface of the discharge column is covered with oil, the discharge end can discharge to the area not covered by the oil, because the distance from the center of the sphere to each point on the spherical surface is equal, and the ignition success rate of the discharge end to the spherical surface is equal, that is, there are infinitely many discharge points, so the partial coverage of the spherical surface does not affect the ignition success rate, and the ignition success rate is higher than that of the traditional single ignition point. The upwardly concave spherical surface facilitates the oil on the bottom surface of the discharge column to slide and gather along the spherical surface to the edge of the spherical surface, and drip from the edge under the action of the oil's own gravity, thereby reducing the long-term accumulation of a large amount of oil on the lower surface of the discharge column, which reduces the ignition success rate.
[0011] Preferably, the inner ring fire cover also includes an inner ring fire cover body, a protective umbrella and an air supply path, the protective umbrella is connected to the outer circumferential surface of the inner ring fire cover body and protrudes from the outer circumferential surface of the inner ring fire cover body in the radial direction of the inner ring fire cover body, the discharge column is connected to the bottom surface of the protective umbrella, the air inlet of the air supply path is opened on the outer circumferential surface of the protective umbrella, and the air outlet of the air supply path is opened on the bottom surface of the protective umbrella.
[0012] In this solution, the provision of a protective umbrella can prevent the discharge column from being exposed to the outside, and avoid the safety hazard caused by the electric spark splashing during the discharge ignition process. The provision of an air supply path can increase the amount of air between the discharge end below the protective umbrella and the ignition point of the discharge column, thereby improving the ignition success rate.
[0013] Preferably, the gas outlet is opened on the spherical surface of the discharge column.
[0014] In this solution, the air outlet is opened on the spherical surface to accurately replenish air to the discharge point and improve the ignition success rate.
[0015] Preferably, there are a plurality of air outlets, and the plurality of air outlets are evenly distributed on the spherical surface.
[0016] In this solution, multiple air outlets are provided to increase the air volume, and the air outlets are evenly distributed on the spherical surface. In addition, each point on the spherical surface has supplementary air, thereby improving the ignition success rate.
[0017] Preferably, the air inlet is a groove body, the groove body is grooved inwardly from the outer peripheral surface of the protective umbrella along the radial direction of the inner ring fire cover body, and the air outlet is connected to the groove body.
[0018] In this solution, the air inlet is set as a slot body to increase the amount of incoming air, thereby increasing the amount of air supplemented under the umbrella and increasing the ignition success rate.
[0019] Preferably, the groove body extends along the radial direction of the inner ring fire cover body and is connected to the outer side of the fire hole of the inner ring fire cover.
[0020] In this solution, the groove body is connected to the radial direction of the inner ring fire cover body and is connected to the outside of the fire hole of the inner ring fire cover, thereby reducing the difficulty of supplementing secondary air caused by setting up a protective umbrella, thereby solving the problem of flame elongation or even burning the outer ring fire cover.
[0021] Preferably, the protective umbrella and the inner ring fire cover body are integrally formed.
[0022] In this solution, the protective umbrella and the inner ring fire cover body are integrally formed, which increases the structural strength of the inner ring fire cover and reduces the difficulty of installation.

The distance from the discharge end to any point on the bottom surface of the discharge column is equal. When the bottom surface of the discharge column is covered with oil, the discharge end can discharge to the area not covered by the oil. Because the distance from the center of the sphere to each point on the spherical surface is equal, the ignition success rate of the discharge end to the spherical surface is equal, that is, there are infinite discharge points, so the partial coverage of the spherical surface does not affect the ignition success rate. Compared with the traditional single ignition point, the ignition success rate is higher. The upwardly concave spherical surface facilitates the oil on the bottom surface of the discharge column to slide and gather along the spherical surface to the edge of the spherical surface, and drip from the edge under the action of the oil's own gravity, thereby reducing the long-term accumulation of a large amount of oil on the lower surface of the discharge column, resulting in a reduction in the ignition success rate. Setting an air supply path can increase the amount of air between the discharge end below the protective umbrella and the ignition point of the discharge column, thereby improving the ignition success rate.

When the bottom surface of the discharge column is covered with oil, the discharge end can discharge to the area not covered by the oil. Because the distance from the center of the sphere to each point on the spherical surface is equal, the ignition success rate of the discharge end to the spherical surface is equal, that is, there are infinite discharge points, so the partial coverage of the spherical surface does not affect the ignition success rate. Compared with the traditional single ignition point, the ignition success rate is higher. The upwardly concave spherical surface facilitates the oil on the bottom surface of the discharge column to slide and gather along the spherical surface to the edge of the spherical surface, and drip from the edge under the action of the oil's own gravity, thereby reducing the long-term accumulation of a large amount of oil on the lower surface of the discharge column, resulting in a reduction in the ignition success rate. The provision of an air supply path can increase the amount of air between the discharge end below the protective umbrella and the ignition point of the discharge column, thereby improving the ignition success rate.

[0045] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0046] like Figures 1 to 7As shown, this embodiment discloses an ignition structure, which includes a discharge column 300 and an ignition needle 400 . The lower surface of the discharge column 300 is a spherical surface 301 that is concave upward. The ignition needle 400 is located below the discharge column 300 , and the discharge end 401 of the ignition needle 400 is located at the center of the spherical surface 301 . The lower surface of the discharge column 300 is set as a spherical surface 301 that is concave upwards, and the discharge end 401 of the ignition needle 400 is located at the center of the spherical surface 301. The distance from the discharge end 401 to any point on the bottom surface of the discharge column 300 is equal. When the bottom surface of the discharge column 300 is covered with oil, the discharge end 401 can discharge to the area not covered by the oil. Because the distance from the center of the ball to each point of the spherical surface 301 is equal, the ignition success rate of the discharge end 401 to the spherical surface 301 is equal, that is, there are infinite discharge points, so the spherical surface 301 is partially covered without affecting the ignition success rate. Compared with the traditional single ignition point, the ignition success rate is higher. The upward concave spherical surface 301 facilitates the oil on the bottom surface of the discharge column 300 to slide and gather along the spherical surface 301 to the edge of the spherical surface 301, and drip from the edge under the action of the oil's own gravity, thereby reducing the long-term accumulation of a large amount of oil on the lower surface of the discharge column 300, resulting in a reduction in the ignition success rate.
[0047] like Figure 5 As shown, along the vertical direction, the projection of the edge of the spherical surface 301 covers the projection of the discharge end 401. The projection of the edge of the spherical surface 301 along the vertical direction on the discharge end 401 of the ignition needle 400 is located on the outer peripheral surface of the discharge end 401 of the ignition needle 400, thereby ensuring that the oil stains sliding down from the edge of the spherical surface 301 of the discharge end 401 will not cover and block the discharge end 401 of the ignition needle 400, ensuring that the ignition success rate will not be affected.
[0048] like Figures 1 to 7 As shown, this embodiment also discloses an inner ring fire cover, which includes the above ignition structure. The lower surface of the discharge column 300 is set as a spherical surface 301 that is concave upward, and the discharge end 401 of the ignition needle 400 is located at the center of the spherical surface 301. The distance from the discharge end 401 to any point on the bottom surface of the discharge column 300 is equal. When the bottom surface of the discharge column 300 is covered with oil, the discharge end 401 can discharge to the area not covered by the oil, because the distance from the center of the sphere to each point of the spherical surface 301 is equal, and the ignition success rate of the discharge end 401 discharging to the spherical surface 301 is equal, that is, there are infinite discharge points, so the partial coverage of the spherical surface 301 does not affect the ignition success rate, and the ignition success rate is higher than that of the traditional single ignition point. The upwardly concave spherical surface 301 facilitates the oil on the bottom surface of the discharge column 300 to slide and gather along the spherical surface 301 toward the edge of the spherical surface 301, and drip from the edge under the action of the oil's own gravity, thereby reducing the long-term accumulation of a large amount of oil on the lower surface of the discharge column 300, which reduces the ignition success rate.
[0049] like Figure 2 , Figure 4As shown, the inner ring fire cover also includes an inner ring fire cover body 100, a protective umbrella 200 and an air supply path 201. The protective umbrella 200 is connected to the outer circumferential surface of the inner ring fire cover body 100 and protrudes from the outer circumferential surface of the inner ring fire cover body 100 in the radial direction of the inner ring fire cover body 100. The discharge column 300 is connected to the bottom surface of the protective umbrella 200. The provision of the protective umbrella 200 can prevent the discharge column 300 from being exposed to the outside and avoid safety hazards caused by sparks splashing during the discharge ignition process.
[0050] like Figure 4 As shown, the air inlet 202 of the air supply path 201 is opened on the outer peripheral surface of the protective umbrella 200, and the air outlet 203 of the air supply path 201 is opened on the spherical surface 301 of the discharge column 300. The air supply path 201 can increase the air volume at the discharge end 401 below the protective umbrella 200 and the ignition point of the discharge column 300, thereby improving the ignition success rate.
[0051] In other alternative embodiments, the air outlet 203 may also be disposed at other positions at the bottom of the protective umbrella 200 or on the outer peripheral surface of the discharge column 300, both of which can replenish air for the discharge point. Preferably, the air outlet 203 is opened on the spherical surface 301 to accurately replenish air for the discharge point and improve the ignition success rate.
[0052] like Figure 4 As shown, there are multiple air outlets 203, and the multiple air outlets 203 are evenly distributed on the spherical surface 301. Arranging multiple air outlets 203 increases the air volume, and the air outlets 203 are evenly distributed on the spherical surface 301, and each point of the spherical surface 301 has supplementary air, which improves the ignition success rate.
[0053] In this embodiment, the number of the air outlets 203 is 5. In other embodiments, the number of the air outlets is determined according to the diameter of the spherical surface 301 of the discharge column 300, the size of the discharge column 300 itself and the diameter of the air outlet. The specific number of the air outlets is not specifically limited here.
[0054] like Figure 7 As shown, the air inlet 202 is a slot body, which is slotted inward from the outer circumference of the protective umbrella 200 along the radial direction of the inner ring fire cover body 100, and the air outlet 203 is connected to the slot body. The air inlet 202 is set as a slot body to increase the amount of incoming air, thereby increasing the amount of air supplemented to the bottom of the protective umbrella 200 and increasing the ignition success rate.
[0055] like Figure 7 As shown, in this embodiment, part of the air inlet 202 passes through the protective umbrella 200 to directly replenish air under the protective umbrella 200, thereby improving the ignition success rate.
[0056] like Figure 7As shown, the groove body extends along the radial direction of the inner ring fire cover body 100 and is connected to the outer side of the fire hole 101 of the inner ring fire cover through the connecting port 204. The groove body extends along the radial direction of the inner ring fire cover body 100 and is connected to the outer side of the fire hole 101 of the inner ring fire cover, reducing the difficulty of supplementing secondary air caused by setting the protective umbrella 200, thereby solving the problem of flame elongation or even burning the outer ring fire cover.
[0057] In this embodiment, the connecting port 204 is opened on the side of the bottom surface of the protective umbrella 200. In other alternative embodiments, the groove body can also penetrate the protective umbrella 200 along the radial direction of the inner ring fire cover body 100, directly connecting the radial outer side and the radial inner side of the protective umbrella 200. The specific opening position of the connecting port 204 is selected according to actual conditions and is not particularly limited here.
[0058] In this embodiment, the protective umbrella 200 and the inner ring fire cover body 100 are integrally formed, thereby increasing the structural strength of the inner ring fire cover and reducing the difficulty of installation.
[0059] This embodiment also discloses a burner, comprising the inner ring fire cover as described above.
[0060] In this solution, the lower surface of the discharge column 300 is set as a spherical surface 301 that is concave upward, and the discharge end 401 of the ignition needle 400 is located at the center of the spherical surface 301. The distance from the discharge end 401 to any point on the bottom surface of the discharge column 300 is equal. When the bottom surface of the discharge column 300 is covered with oil, the discharge end 401 can discharge to the area not covered by the oil. Because the distance from the center of the sphere to each point of the spherical surface 301 is equal, the ignition success rate of the discharge end 401 to the spherical surface 301 is equal, that is, there are infinite discharge points, so the partial coverage of the spherical surface 301 does not affect the ignition success rate. Compared with the traditional single ignition point, the ignition success rate is higher. The upward concave spherical surface 301 facilitates the oil on the bottom surface of the discharge column 300 to slide and gather along the spherical surface 301 to the edge of the spherical surface 301, and drip from the edge under the action of the oil's own gravity, thereby reducing the long-term accumulation of a large amount of oil on the lower surface of the discharge column 300, resulting in a reduction in the ignition success rate. Providing the air supply path 201 can increase the amount of air between the discharge end 401 below the protective umbrella 200 and the ignition point of the discharge column 300, thereby improving the ignition success rate.
