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 discharge column is prone to depositing oil stains, resulting in a decrease in the ignition success rate, and to provide an inner ring fire cover and a burner containing the same.

The discharge column is detachably inserted into the ventilation groove through the assembly groove and is clamped in the ventilation groove.

[0006] In this solution, the discharge column is detachably connected to the protective umbrella. When a lot of oil is deposited on the discharge column, the discharge column can be removed in time for cleaning or replacement, thereby ensuring that the ignition success rate is not affected by the oil coverage. In the process of disassembling and assembling the discharge column, the assembly groove is used for the passage of the discharge column. After the discharge column is placed in the ventilation groove, because the assembly groove is connected to the ventilation groove, the assembly groove is used to replenish air for the discharge ignition point. The ventilation groove connects the outer side of the outer peripheral surface of the protective umbrella and the lower surface of the protective umbrella to replenish air for the discharge ignition point, thereby improving the ignition success rate. The assembly groove structure can play a dual role, reduce costs, and has a simple structure.

[0007] Preferably, the axis of the assembly groove is perpendicular to the axis of the ventilation groove, a protrusion is provided on the outer peripheral surface of the discharge column, the discharge column moves from the opening of the assembly groove along the axial direction of the assembly groove toward the ventilation groove, and the protrusion is clamped in the ventilation groove to limit the vertical movement of the discharge column.

[0010] In this solution, the protrusion of the discharge column enters the ventilation groove through the assembly groove, and the inner wall surface of the ventilation groove not penetrated by the assembly groove serves as a limiting portion. By selecting the discharge column, the bottom surface of the protrusion abuts against the upper surface of the limiting portion, and the limiting portion acts on the protrusion to balance the gravity of the discharge column itself, thereby limiting the movement of the discharge column in the vertical direction. The process is simple, the structure is reliable, and the cost is low.

[0011] Preferably, the number of the protrusions is multiple and they are evenly arranged on the outer peripheral surface of the discharge column.

[0043] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0044] like Figures 1 to 7 As shown, this embodiment discloses an inner ring fire cover, which includes an inner ring fire cover body 100, a protective umbrella 200, and a discharge column 300. The protective umbrella 200 is connected to the outer peripheral surface of the inner ring fire cover body 100 and protrudes from the outer peripheral surface of the inner ring fire cover body 100 in the radial direction of the inner ring fire cover body 100.

[0045] like Figure 6 As shown, the protective umbrella 200 includes a ventilation groove 201, which is grooved inward from the outer peripheral surface of the protective umbrella 200 along the radial outer side of the inner ring fire cover body 100 to the radial inner side, and the ventilation groove 201 is connected to the lower surface of the protective umbrella 200. The ventilation groove 201 connects the outer side of the outer peripheral surface of the protective umbrella 200 and the lower side of the protective umbrella 200, so as to supplement air for the discharge ignition point and improve the ignition success rate.

[0046] like Figure 6 As shown, the protective umbrella 200 includes an assembly groove 202, which is opened on the lower surface of the protective umbrella 200, and the discharge column 300 is detachably connected to the protective umbrella 200 through the assembly groove 202. The discharge column 300 is detachably connected to the protective umbrella 200. When a lot of oil is deposited on the discharge column 300, the discharge column 300 can be removed in time for cleaning or replacement, thereby ensuring that the ignition success rate is not affected by the oil coverage.

[0047] like Figure 3 As shown, the assembly groove 202 is connected to the ventilation groove 201, and the discharge column 300 is detachably connected to the ventilation groove 201 through the assembly groove 202. During the process of disassembling and assembling the discharge column 300, the assembly groove 202 is used for the passage of the discharge column 300. After the discharge column 300 is fixed to the ventilation groove 201, because the assembly groove 202 is connected to the ventilation groove 201, the assembly groove 202 is used to supplement air for the discharge ignition point to improve the ignition success rate. The assembly groove 202 can play a dual role in one structure, reduce costs, and has a simple structure.

[0048] like Figure 4 As shown, in this embodiment, the assembly groove 202 is cross-shaped, part of the lower inner wall surface of the ventilation groove 201 is penetrated by the assembly groove 202, and the lower inner wall surface of the ventilation groove 201 between two adjacent assembly grooves 202 that is not penetrated by the assembly groove 202 serves as a limiting portion 203.

[0049] In other alternative embodiments, the assembly groove 202 may also be in other shapes, the shape of the assembly groove 202 matches the shape of the discharge column 300, and a limiting portion 203 is provided in the ventilation groove 201, and the specific shape of the assembly groove 202 is not limited.

[0050] like Figure 3 As shown, in this embodiment, the axis of the assembly groove 202 is perpendicular to the axis of the ventilation groove 201. Figure 7 As shown, a protrusion 301 is provided on the outer peripheral surface of the discharge column 300 .

[0051] When installing the discharge column 300 , the protrusion 301 is aligned with the assembly groove 202 , and the discharge column 300 moves from the opening of the assembly groove 202 along the axis direction of the assembly groove 202 toward the ventilation groove 201 .

[0052] like Figure 4 As shown, after the protrusion 301 of the discharge column 300 enters the ventilation groove 201, the bottom surface of the protrusion 301 of the rotating discharge column 300 abuts against the limiting portion 203, and the limiting portion 203 acts on the protrusion 301 to balance the gravity of the discharge column 300, thereby limiting the movement of the discharge column 300 in the vertical direction.

[0053] When removing the discharge column 300, the discharge column 300 is rotated to align the protrusion 301 with the assembly groove 202, and the discharge column 300 is taken out of the ventilation groove 201 from the assembly groove 202, and the discharge column 300 is taken out. The operation is simple, the structure is simple, and the assembly and disassembly of the discharge column 300 is completed at a low cost, thereby ensuring that the ignition success rate is not affected by oil stains.

[0054] like Figure 7 As shown, in this embodiment, the number of protrusions 301 of the discharge column 300 is four and they are evenly arranged on the outer circumference of the discharge column 300. The plurality of protrusions 301 are arranged on the outer circumference of the discharge column 300 so that the discharge column 300 is evenly stressed without deviation, thereby improving the stability of the fixation of the discharge column 300.

[0055] In other alternative embodiments, the number and shape of the protrusions 301 can be specifically selected as needed, and the shape of the discharge column 300 should be compatible with the shape of the assembly groove 202 , or at least be able to pass through the assembly groove 202 and abut against the limiting portion 203 .

[0056] In this embodiment, a rigid structure is used to achieve the purpose of locking by rotation. In other replaceable embodiments, elastic parts such as rubber can be provided on the discharge column 300, and the elastic parts can be compressed to pass through the assembly groove 202 and be locked in the ventilation groove 201 by restoring the deformation, thereby achieving the purpose of disassembly and assembly.

[0057] like Figure 3 As shown, the ventilation groove 201 penetrates the protective umbrella 200 from the outer peripheral surface of the protective umbrella 200 to the radial inner side of the inner ring fire cover body 100. The ventilation groove 201 can not only replenish air for the ignition point, but also replenish air for the fire hole of the inner ring fire cover, reducing the difficulty of replenishing secondary air caused by the installation of the protective umbrella 200, thereby solving the problem of flame elongation or even burning the outer ring fire cover.

[0058] In this embodiment, the inner ring fire cover body 100 and the protective umbrella 200 are integrally formed to enhance the structural strength.

[0059] In other alternative embodiments, the protective umbrella 200 is detachably connected to the inner ring fire cover body 100, which is convenient for cleaning and replacement of the protective umbrella 200, and also convenient for disassembling the discharge column 300 after removing the protective umbrella 200, thereby improving the ignition success rate.

[0060] like Figure 1-Figure 3 As shown, this embodiment also discloses a burner, including the inner ring fire cover as above. The burner includes an ignition needle 400, and the ignition needle 400 is located below the discharge column 300, and the central axis of the ignition needle 400 coincides with the central axis of the discharge column 300. That is, the central axis of the ignition needle 400 passes through the center of the discharge column 300, and the discharge end of the ignition needle 400 faces the lower surface of the discharge column 300, thereby improving the ignition success rate.

[0061] like Figure 3 As shown, the lower surface of the discharge column 300 includes a convex point 302, the convex point 302 faces the ignition needle 400, and the central axis of the convex point 302 coincides with the central axis of the ignition needle 400. An arc is formed between the discharge end of the ignition needle 400 and the convex point 302, thereby igniting the gas ejected from the inner ring fire cover. The convex point 302 is provided to facilitate the formation of an arc to improve the ignition success rate.
