Description

Technical Field

[0001] This utility model relates to an inner furnace core and a furnace core assembly using the inner furnace core, belonging to the field of burner technology. Background Technology

[0002] Various furnace core structures have been disclosed in the prior art. For example, Chinese utility model patent CN208936148U, entitled "A Furnace Core for Complete Combustion of Energy," discloses a furnace core comprising a furnace core body and a flame distribution frame disposed within the furnace core body. An oil injector is located at the lower part of the furnace core body, and atomized oil is blown into the furnace core cavity by a blower and ignited by an igniter. Another example is Chinese invention patent application CN120027416A, entitled "An Energy-Saving and Consumption-Reducing Furnace Core and a Burner Using the Furnace Core," which discloses an energy-saving and consumption-reducing furnace core comprising a furnace core body, a furnace cavity formed within the furnace core body, and a first flame distribution element and a second flame distribution element disposed within the furnace cavity. These first and second flame distribution elements enable more complete fuel atomization.

[0003] In existing furnace core assemblies, the upper part of the furnace core is more prone to burnout due to the higher temperature in the upper part of the furnace cavity. Once the furnace core burns out, the entire furnace core needs to be replaced, which is costly.

[0004] Based on the above issues, the applicant conducted research, which led to this case. Utility Model Content

[0005] The purpose of this utility model is to provide an inner furnace core that can better protect the furnace core and improve the combustion effect. Another purpose of this utility model is to propose a furnace core assembly using this inner furnace core.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An inner furnace core includes a cylinder, the lower end of which is a sealed end and the upper end of which is an open end. The sealed end is provided with a through hole communicating with the inner cavity of the cylinder. The outer wall of the open end has a support portion mounted on the upper part of the outer furnace core. The upper part of the open end is higher than the upper end of the outer furnace core.

[0008] In a preferred embodiment of this invention, the support portion is a horizontal support platform.

[0009] As a preferred embodiment of this utility model, the open end is formed into a flared mouth that is larger at the top and smaller at the bottom.

[0010] In a preferred embodiment of this invention, the outer wall of the capping end forms an outwardly extending annular retaining edge.

[0011] As a preferred embodiment of this utility model, the cylinder is provided with a plurality of air-assisted holes communicating with the inner cavity of the cylinder.

[0012] In a preferred embodiment of this utility model, there are multiple through holes arranged around the central axis of the cylinder.

[0013] As a preferred embodiment of this utility model, the upper part of the open end is provided with a flame spreader cover, which abuts against the open end. The flame spreader cover is provided with multiple flame outlet holes, and a combustion chamber is formed between the flame spreader cover and the sealed end.

[0014] A furnace core includes an outer furnace core, the lower end of which is a fuel inlet and the upper end of which is a flame outlet. It also includes an inner furnace core, which includes a cylindrical body. The lower end of the cylindrical body is a sealed end that extends into the outer furnace core. The upper end of the cylindrical body is an open end. The sealed end has a through hole communicating with the inner cavity of the cylindrical body. The outer wall of the open end has a support portion mounted on the upper part of the outer furnace core, and the upper part of the open end is higher than the upper end of the outer furnace core.

[0015] In a preferred embodiment of this utility model, the upper end of the outer furnace core forms a support surface, the support part is a horizontal support platform, the horizontal support platform presses against the support surface, and the outer wall of the cap end is provided with an annular retaining edge extending towards the inner wall of the outer furnace core.

[0016] As a preferred embodiment of this utility model, it also includes a cylindrical outer shell, the upper end of the outer furnace core is provided with an outwardly extending support flange, the support flange is mounted on the upper end of the outer shell, a fire-gathering ring is provided on the support flange, and the open end is located inside the fire-gathering ring.

[0017] The inner furnace core proposed in this invention can be used with various outer furnace cores. During use, it is mounted on top of the outer furnace core, thus isolating the upper part of the outer furnace core from the flame inside the inner furnace core. This prevents direct scorching of the upper part of the outer furnace core by the flame, reducing the chance of the outer furnace core burning. If the inner furnace core burns out, it only needs to be replaced. By incorporating the inner furnace core, this invention can also compress and release the fuel entering from the outer furnace core, thereby further improving fuel atomization and combustion efficiency. This invention also proposes a furnace core using this inner furnace core, which protects the outer furnace core and extends its service life. Attached Figure Description

[0032] To better understand the technical solution of this utility model, the following description is provided in more detail with reference to the embodiments.

[0033] Reference Figures 1 to 4 An inner furnace core 10 includes a cylindrical body 11. The lower end of the cylindrical body 11 is a sealed end 12, which is integrally formed with the cylindrical body 11. Alternatively, the sealed end 12 can be a separate component mounted on the lower end of the cylindrical body 11. The upper end of the cylindrical body 11 is an open end 13. The sealed end 12 has multiple through holes 19 communicating with the inner cavity of the cylindrical body 11, allowing fuel and flame to enter the inner cavity of the cylindrical body 11. The outer wall of the open end 13 has a support portion 16 mounted on the upper part of the outer furnace core 20, with the upper part of the open end 13 higher than the upper part of the outer furnace core 20. The support portion 16 of this invention can be mounted on the top of the outer furnace core 20, or a support area can be provided on the upper part of the inner wall of the outer furnace core 20, with the support portion 16 mounted on the support area.

[0034] In a preferred embodiment of this utility model, the support part 16 is a horizontal support platform, which is mounted on the top of the outer furnace core 20.

[0035] As a preferred embodiment of this utility model, the open end 13 forms a funnel-shaped opening 15 that is larger at the top and smaller at the bottom, so that the fuel and flame can be further expanded and dispersed through the upper part of the furnace body, thereby improving combustion efficiency.

[0036] As a preferred embodiment of this invention, the outer wall of the cap end 12 forms an outwardly extending annular baffle 14. This annular baffle 14 can reduce the distance between the lower part of the cylinder 11 and the outer furnace core 20, reduce the area between the inner wall of the outer furnace core 20 and the outer wall of the cylinder 11, and reduce the risk of the upper part of the outer furnace core 20 being burned.

[0037] As a preferred embodiment of the present invention, the cylinder 11 is provided with a plurality of air-aiding holes 18 communicating with the inner cavity of the cylinder 11. The air-aiding holes 18 are generally located in the middle of the entire inner furnace core 10 along the axial direction. In the embodiment, their direction is obliquely upward from the outside to the inside.

[0038] As a preferred embodiment of the present invention, there are multiple through holes 19, which are arranged around the central axis of the cylinder 11. In the embodiment, the through holes 19 are arranged near the periphery of the cap end 12.

[0039] In a preferred embodiment of this invention, a flame distribution cover 30 is provided on the upper part of the open end 13, and the flame distribution cover 30 abuts against the open end 13. The flame distribution cover 30 has multiple outlet holes 31, and a combustion chamber 100 is formed between the flame distribution cover 30 and the sealed end 12. In this embodiment, the flame distribution cover 30 is generally shaped like a cap, and a recessed platform 17 is provided on the upper end of the inner furnace core 10. The flame distribution cover 30 presses against the recessed platform 17. The combustion chamber 100 formed by the flame distribution cover 30 and the sealed end 12 is a concentrated combustion area with a high internal temperature. The flame coming out of the combustion chamber 100 directly acts on the kitchen utensils to be heated.

[0040] This utility model also provides a furnace core, including an outer furnace core 20. The lower end of the outer furnace core 20 is a fuel inlet, and the fuel inlet is correspondingly provided with an atomizing nozzle and a blower channel. These are structures in the prior art and are not the focus of this application's improvement, so they will not be described in detail here. The upper end of the outer furnace core 20 is a flame outlet, and it also includes an inner furnace core 10 disposed at the flame outlet, through which the flame of the original single outer furnace core 20 is received. The inner furnace core 10 of this utility model includes a cylindrical body 11. The lower end of the cylindrical body 11 is a sealed end 12, which extends into the outer furnace core 20. The upper end of the cylindrical body 11 is an open end 13. The sealed end 12 is provided with a through hole 19 communicating with the inner cavity of the cylindrical body 11. The outer wall of the open end 13 has a support part 16 mounted on the upper part of the outer furnace core 20. The upper part of the open end 13 is higher than the upper part of the outer furnace core 20. That is, the flame no longer directly sprays out from the upper part of the outer furnace core 20, but is transferred to the inner furnace core 10. Although the heat of the inner furnace core 10 can be transferred to the outer furnace core 20, the flame does not directly act on the upper part of the outer furnace core 20, which can reduce the heating temperature of the outer furnace core 20 and also avoid the flame directly acting on the upper part of the outer furnace core 20, causing further oxidation and damage to the upper part of the outer furnace core 20.

[0041] In a preferred embodiment of the present invention, the upper end of the outer furnace core 20 forms a support surface, the support part 16 is a horizontal support platform, the horizontal support platform presses against the support surface, and the outer wall of the cap end 12 is provided with an annular retaining edge 14 extending toward the inner wall of the outer furnace core 20.

[0042] In a preferred embodiment of this invention, a cylindrical outer shell 50 is also included. A blower is connected to the bottom of the cylindrical outer shell 50. In this invention, the outer shell 50 primarily serves for isolation and aesthetic purposes. No flame burns in the area between the interior of the outer shell 50 and the outer furnace core 20; therefore, the outer shell 50 is not considered part of the furnace core. The upper end of the outer furnace core 20 has an outwardly extending support flange, which is mounted on the upper end of the outer shell 50. A flame-gathering ring 40 is provided on the support flange to concentrate the flame. The open end 13 is located inside the flame-gathering ring 40 and is lower than the upper end of the flame-gathering ring 40. In this invention, the side wall of the outer furnace core 20 has multiple holes 21 for supplying air and directing it into the inner furnace core 10, thus aiding combustion.

[0043] The scope of protection of this utility model is not limited to this embodiment. Any similar modifications made to it are considered to be within the scope of protection of this utility model.
