The components of the embodiments of the present invention can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without inventive effort shall fall within the scope of the technical solutions claimed for protection by the present invention.

[0025] Example:

[0026] like Figures 1 to 5 As shown, this embodiment provides a burner, including an ignition distributor 1, an inner cover 2 and an outer cover 3, wherein the inner cover 2 is detachably or fixedly arranged on the ignition distributor 1, and the outer cover 3 is assembled with the ignition distributor 1 through the inner cover 2, and an accommodating cavity 31 with an open lower end is defined in the outer cover 3, and the inner cover 2 is detachably sleeved in the accommodating cavity 31, an external fire hole 32 is opened on the outer cover 3, and an internal fire hole 21 connected to the external fire hole 32 is opened on the inner cover 2.

[0027] In this embodiment, the inner cover 2 is detachably or fixedly arranged on the fire divider 1, and the outer cover 3 is assembled with the fire divider 1 through the inner cover 2. A accommodating chamber 31 with an open lower end is defined in the outer cover 3, and the inner cover 2 is cooperatively sleeved in the accommodating chamber 31, so that the outer cover 3 and the inner cover 2 are detachably connected together. An external fire hole 32 is opened on the outer end wall of the outer cover 3, and an internal fire hole 21 connected to the external fire hole 32 is correspondingly opened on the outer end wall of the inner cover 2. Since an air separation cavity is defined in the fire divider 1, when the inner cover 2 and the outer cover 3 are assembled together, a communication relationship is established among the external fire hole 32, the internal fire hole 21 and the air separation cavity. When the inner cover 2 and the outer cover 3 are disassembled, the communication relationship among the external fire hole 32, the internal fire hole 21 and the air separation cavity is disconnected. The structure is simple and easy to disassemble and assemble, which can effectively reduce the production cost of the product, thereby further improving the competitiveness of the product.

[0028] Preferably, the inner cover 2 and the fire distributor 1 are integrally formed, so that the outer cover 3 can be quickly assembled on the fire distributor 1 through the inner cover 2. Of course, after the inner cover 2 and the outer cover 3 are assembled together, post-processing such as drilling is performed to ensure that the hole diameters between the inner cover 2 and the outer cover 3 are consistent.

[0029] Furthermore, a fixing portion 11 is provided on the fire distributor 1 , and a connecting portion 22 is provided on the inner cover 2 . The connecting portion 22 is cooperatively connected with the fixing portion 11 so that the inner cover 2 and the fire distributor 1 are assembled together.

[0030] Preferably, a notch is provided on the ignition distributor 1 to form the fixing portion 11 , and a protrusion is provided downwardly on the inner cover 2 to form the connecting portion 22 , which extends into the notch so that the connecting portion 22 is matched and connected with the fixing portion 11 .

[0031] In this embodiment, since an air separation cavity is defined within the fire divider 1, a recess is provided within the air separation cavity of the fire divider 1 to form a fixing portion 11, and a protrusion is provided on the bottom wall of the inner cover 2 to form a connecting portion 22. The protrusion extends into the recess so that the connecting portion 22 and the fixing portion 11 are matched and connected together, thereby assembling the inner cover 2 and the fire divider 1 together, thereby limiting the displacement of the inner cover 2 and facilitating the assembly between the fire divider 1 and the inner cover 2. Of course, in this embodiment, a protrusion may also be provided within the air separation cavity of the fire divider 1 to form a fixing portion 11, and a recess is provided on the bottom wall of the inner cover 2 to form a connecting portion 22. The protrusion extends into the recess so that the connecting portion 22 and the fixing portion 11 are matched and connected together, thereby also assembling the inner cover 2 and the fire divider 1 together.

[0032] Specifically, a positioning portion 33 is provided on the outer cover 3 , and a matching portion 23 is provided on the inner cover 2 . The matching portion 23 is matched and connected with the positioning portion 33 to limit the assembly work between the outer cover 3 and the inner cover 2 .

[0033] Furthermore, a boss is protruded downward on the bottom wall of the outer cover 3 to form a positioning portion 33, and a through hole is opened on the top wall of the inner cover 2 to form a matching portion 23, and the boss extends into the through hole to make the positioning portion 33 and the matching portion 23 matched and connected together.

[0034] In this embodiment, a boss is provided on the bottom wall of the outer cover 3 to form a positioning portion 33, and a through hole is provided on the top wall of the inner cover 2 to form a mating portion 23. The boss extends into the through hole so that the positioning portion 33 and the mating portion 23 are matingly connected together. In this way, the outer cover 3 and the inner cover 2 are matingly assembled together, thereby limiting the assembly work between the outer cover 3 and the inner cover 2, that is, limiting the displacement of the outer cover 3 by the inner cover 2, and also facilitating the assembly between the outer cover 3 and the inner cover 2. Of course, in this embodiment, a through hole can also be provided on the bottom wall of the outer cover 3 to form the positioning portion 33, and a boss is provided on the top wall of the inner cover 2 to form the mating portion 23, and the boss extends into the through hole so that the positioning portion 33 and the mating portion 23 are matingly connected together.

[0035] Furthermore, an upper end of the outer end wall of the inner cover 2 and a top wall of the accommodating cavity 31 are spaced apart.

[0036] Preferably, the upper end of the inner cover 2 is open.

[0037] In this embodiment, the outer cover 3 has an outer end wall, an upper end wall and an inner end wall connected in sequence, and the outer end wall, the upper end wall and the inner end wall are matched and connected to jointly define a accommodating cavity 31 with an open lower end. When the inner cover 2 is arranged in the accommodating cavity 31, the upper end of the outer end wall of the inner cover 2 and the top wall of the accommodating cavity 31 are spaced apart. At the same time, the upper end of the inner cover 2 is preferably open, so that the product can achieve the purpose of saving materials, thereby effectively reducing the production cost of the product.

[0038] Specifically, the material of the outer cover 3 is resistant to high temperatures above 700°C.

[0039] Preferably, the material of the inner cover 2 is different from that of the outer cover 3 .

[0040] Particularly, the outer cover 3 is made of copper, and the inner cover 2 is made of aluminum.

[0041] In this embodiment, the material of the outer cover 3 is preferably a material that can withstand high temperatures above 700°C, that is, the parts of the fire cover involved in the fire are all made of a material that can withstand high temperatures above 700°C. At the same time, the material of the inner cover 2 is different from that of the outer cover 3. In this way, the amount of expensive materials used in the existing fire cover can be effectively reduced without reducing the wall thickness of the fire cover or reducing the working performance. At the same time, by replacing the inner cover 2 with a cheaper material so that the material of the inner cover 2 is different from that of the outer cover 3, the overall cost of the product is reduced, thereby improving the product competitiveness. More preferably, the material of the outer cover 3 is copper and the material of the inner cover 2 is aluminum, but they are not limited to the above materials. Other more suitable materials can also be selected according to actual needs.

[0042] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
