Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention can be arranged and designed in various different configurations.

[0022] 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.

[0023] Example:

[0024] like Figures 1 to 3 As shown, this embodiment provides a fire cover, comprising an outer cover (1) and an inner cover (2), wherein a receiving cavity (3) with an open lower end is defined in the outer cover (1), and the inner cover (2) is detachably mounted in the receiving cavity (3), an outer fire hole (11) is provided on the outer cover (1), and an inner fire hole (21) connected to the outer fire hole (11) is provided on the inner cover (2).

[0025] In this embodiment, the fire cover is preferably applied to the fire divider, so that the inner cover (2) is detachably or fixedly arranged on the fire divider, and the outer cover (1) is assembled with the fire divider through the inner cover (2), and a receiving cavity (3) with an open lower end is defined in the outer cover (1), and the inner cover (2) is matched and sleeved in the receiving cavity (3), so that the outer cover (1) and the inner cover (2) are detachably connected together, and an outer fire hole (11) is opened on the outer end wall of the outer cover (1), and an inner fire hole (11) is opened on the outer end wall of the inner cover (2). An inner fire hole (21) connected to the outer fire hole (11) is correspondingly provided on the outer end wall of the cover (2). When the inner cover (2) and the outer cover (1) are assembled together, the outer fire hole (11) and the inner fire hole (21) are connected. When the inner cover (2) and the outer cover (1) are disassembled, the outer fire hole (11) and the inner fire hole (21) are 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.

[0026] Furthermore, the aperture of the outer fire hole (11) is the same as or different from the aperture of the inner fire hole (21).

[0027] Preferably, when the aperture of the outer fire hole (11) is different from the aperture of the inner fire hole (21), the aperture of the inner fire hole (21) is smaller than the aperture of the outer fire hole (11).

[0028] In this embodiment, when the aperture of the outer fire hole (11) is the same as the aperture of the inner fire hole (21), the inner cover (2) and the outer cover (1) are assembled together and then subjected to post-processing such as drilling, which helps to ensure that the apertures of the inner cover (2) and the outer cover (1) are consistent. In addition, the apertures of the inner cover (2) and the outer cover (1) can be set to be different, so that a step is formed between the outer fire hole (11) and the inner fire hole (21). More preferably, by making the aperture of the inner fire hole (21) smaller than the aperture of the outer fire hole (11), the tempering performance can be further improved. Of course, the aperture of the outer fire hole (11) near the outlet of the ignition distributor can also be reduced to make the flame more uniform.

[0029] Specifically, a positioning portion (12) is provided on the outer cover (1), and a matching portion (22) is provided on the inner cover (2); the matching portion (22) is matched and connected with the positioning portion (12) to limit the assembly work between the outer cover (1) and the inner cover (2).

[0030] Furthermore, a boss is provided on the bottom wall of the outer cover (1) to form the positioning portion (12), and a through hole is provided on the top wall of the inner cover (2) to form the matching portion (22), and the boss extends into the through hole so that the positioning portion (12) and the matching portion (22) are matched and connected together.

[0031] In this embodiment, a boss is provided on the bottom wall of the outer cover (1) to form a positioning portion (12), and a through hole is provided on the top wall of the inner cover (2) to form a matching portion (22). The boss is inserted into the through hole so that the positioning portion (12) and the matching portion (22) are matched and connected together, so that the outer cover (1) and the inner cover (2) are matched and assembled together, thereby limiting the assembly work between the outer cover (1) and the inner cover (2), that is, the displacement of the outer cover (1) is limited by the inner cover (2), and at the same time, it is also beneficial to the assembly between the outer cover (1) 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 (1) to form a positioning portion (12), and a boss is provided on the top wall of the inner cover (2) to form a matching portion (22). The boss is inserted into the through hole so that the positioning portion (12) and the matching portion (22) are matched and connected together.

[0032] Furthermore, an upper end of the outer end wall of the inner cover (2) and a top wall of the accommodating cavity (3) are spaced apart.

[0033] Preferably, the upper end of the inner cover (2) is open.

[0034] In this embodiment, the outer cover (1) 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 connected together to define a receiving cavity (3) with an open lower end. When the inner cover (2) is sleeved in the receiving cavity (3), the upper end of the outer end wall of the inner cover (2) and the top wall of the receiving cavity (3) 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.

[0035] Specifically, the material of the outer cover (1) is resistant to high temperatures above 700°C.

[0036] Preferably, the material of the inner cover (2) is different from the material of the outer cover (1).

[0037] In particular, the outer cover (1) is made of copper, and the inner cover (2) is made of aluminum.

[0038] In this embodiment, the material of the outer cover (1) is preferably a material that can withstand high temperatures above 700°C, that is, the parts of the fire cover that are 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 (1). 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 and without 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 (1), the overall cost of the product is reduced, thereby improving the competitiveness of the product. More preferably, the material of the outer cover (1) is copper and the material of the inner cover (2) is aluminum, but it is not limited to the above materials. Other more suitable materials can also be selected according to actual needs.

[0039] In this embodiment, since a gas separation cavity is defined in the fire divider, a recess is provided in the gas separation cavity of the fire divider to form a fixing portion, a protrusion is provided on the bottom wall of the inner cover (2) to form a connecting portion, and the protrusion extends into the recess so that the connecting portion and the fixing portion are matched and connected together, thereby assembling the inner cover (2) and the fire divider together, thereby limiting the displacement of the inner cover (2) and facilitating the assembly between the fire divider and the inner cover (2). Of course, in this embodiment, a protrusion can also be provided in the gas separation cavity of the fire divider to form a fixing portion, and a recess is provided on the bottom wall of the inner cover (2) to form a connecting portion, and the protrusion extends into the recess so that the connecting portion and the fixing portion are matched and connected together, thereby also assembling the inner cover (2) and the fire divider together.

[0040] 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.
