Description

Technical Field

[0001] The utility model relates to a central fire cover of a burner. Background Art

[0002] Since the burner center fire cover in the prior art has no indicating structure, the center fire cover is installed randomly, resulting in the center fire outlet hole being unable to directly align with the ignition needle, affecting the normal ignition and stability of the center fire cover. Utility Model Content

[0003] The utility model aims to provide a technical solution for a burner center fire cover to address the deficiencies in the prior art. The design of the opening can not only increase safety indication and consistency, but also make the opening face the ignition pinhole when assembling the center fire cover, thereby enhancing the effectiveness and stability of ignition.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A burner center fire cover, comprising

[0006] A fire cover body;

[0007] Features:

[0008] A retaining ring is provided on the top of the fire cover body, and an opening is provided on the retaining ring; through the design of the opening, not only can the safety indication and consistency be increased, but also when the central fire cover is assembled, the opening is made to face the ignition pin hole, thereby enhancing the effectiveness and stability of ignition.

[0009] Furthermore, the fire cover body is provided with at least one group of central fire outlet holes and flame stabilizing holes along the circumferential direction, and each group of central fire outlet holes and flame stabilizing holes are staggered and evenly distributed, thereby improving the stability and reliability of gas combustion and making the flame distribution more uniform.

[0010] Furthermore, the inner diameter of the central fire outlet hole is larger than the inner diameter of the flame stabilizing hole.

[0011] Furthermore, two upper and lower adjacent central fire outlet holes and flame stabilizing holes are arranged parallel to each other, making the central flame more stable and reliable.

[0012] Furthermore, the central fire outlet hole and the flame stabilizing hole are both arranged to be inclined upward from the inner side surface to the outer side surface of the fire cover body, so as to ensure that the mixed gas is transported in an inclined direction and improve the combustion efficiency of the fuel gas.

[0013] Furthermore, the outer edge of the retaining ring protrudes from the outer edge of the fire cover body, which can protect the central fire hole and the flame stabilizing hole, reduce the soup from flowing into the burner through the central fire hole and the flame stabilizing hole, or cause blockage of the central fire hole and the flame stabilizing hole, affecting the transportation efficiency of the mixed gas.

[0014] Furthermore, a slot is provided on the inner side of the bottom of the fire cover body to facilitate stable assembly of the central fire cover.

[0015] Furthermore, the card slot has a ring-shaped structure.

[0016] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0017] 1. The opening design not only increases safety indication and consistency, but also makes the opening face the ignition pin hole when assembling the center fire cover, thus enhancing the effectiveness and stability of ignition.

[0018] 2. The fire cover body is provided with at least one group of central fire outlet holes and flame stabilizing holes along the circumferential direction, and each group of central fire outlet holes and flame stabilizing holes are staggered and evenly distributed, so as to improve the stability and reliability of gas combustion and make the flame distribution more uniform.

[0019] 3. The central fire outlet hole and the flame stabilizing hole are arranged upwardly and inclined from the inner side of the fire cover body to the outer side, so as to ensure that the mixed gas is transported in the inclined direction and improve the combustion efficiency of the gas.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0029] like Figures 1 to 4 As shown, a burner center fire cover of the utility model comprises a fire cover body 1, a retaining ring 2 is provided on the top of the fire cover body 1, and an opening 3 is provided on the retaining ring 2; through the design of the opening 3, not only the safety indication and consistency can be increased, but also when the center fire cover is assembled, the opening 3 is directed toward the ignition pinhole, thereby enhancing the effectiveness and stability of ignition.

[0030] The outer edge of the retaining ring 2 protrudes from the outer edge of the fire cover body 1, which can protect the central fire hole 4 and the flame stabilizing hole 5, reduce the soup from flowing into the burner through the central fire hole 4 and the flame stabilizing hole 5, or cause the central fire hole 4 and the flame stabilizing hole 5 to be blocked, affecting the transportation efficiency of the mixed gas.

[0031] The fire cover body 1 is provided with at least one group of central fire holes 4 and flame stabilizing holes 5 along the circumferential direction. The present application preferably adopts two groups of central fire holes 4 and flame stabilizing holes 5 which are arranged in parallel with each other, and each group of central fire holes 4 and flame stabilizing holes 5 are staggered and evenly distributed, so as to improve the stability and reliability of gas combustion and make the flame distribution more uniform.

[0032] The inner diameter of the central fire outlet hole 4 is larger than the inner diameter of the flame stabilizing hole 5, which is not only beneficial to the output of the mixed gas, but also beneficial to stabilizing the central fire, thereby improving the stability and reliability of the central fire during combustion.

[0033] The two upper and lower adjacent central fire outlet holes 4 and flame stabilizing holes 5 are arranged parallel to each other, so that the central flame is more stable and reliable.

[0034] The central fire outlet hole 4 and the flame stabilizing hole 5 are both arranged to be inclined upward from the inner side surface to the outer side surface of the fire cover body 1, so as to ensure that the mixed gas is transported in the inclined direction and improve the combustion efficiency of the fuel gas.
