Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Two limiting mechanisms 6 are symmetrically arranged on the top surface of the connecting pipe 1, and are used to limit the air inlet pipe 4 and the burner body 5. The limiting mechanism 6 includes an L-shaped vertical plate 61 fixed on the top surface of the connecting pipe 1, a rotating cylinder 62 rotatably connected to the vertical plate end of the vertical plate 61, a screw 63 rotatably connected to the rotating cylinder 62, a moving column 64 coaxially fixed to the surface of the screw 63 on one side close to the air inlet pipe 4, and a limiting rod 65 coaxially fixed to the surface of the moving column 64 on one side close to the air inlet pipe 4 and used to limit the air inlet pipe 4, and a moving rod 66 slidably connected to the horizontal plate end of the vertical plate 61 on the same side is fixed on the circumferential outer wall of the moving column 64. By setting the connecting pipe 1, the entire burner can be connected to the gas pipe 2, and by setting the ventilation pipe 3 and the air inlet pipe 4, the ventilation operation of the gas can be performed. By setting the two limiting mechanisms 6, the air inlet pipe 4 can be limited, and the burner body 5 can be limited, which makes it easy to disassemble, replace or clean the burner body 5.

[0029] In this embodiment, a guide groove is provided on the bottom surface of the horizontal plate end of the vertical plate 61, and a guide block 67 is fixed on the top surface of the moving rod 66, which is slidably connected to the guide groove on the bottom surface of the horizontal plate end of the vertical plate 61 on the same side, so as to guide the movement of the moving rod 66, and thus indirectly guide the movement of the limit rod 65.

[0030] In addition, a through hole connected to its inner cavity is provided on the circumferential outer wall of the air inlet pipe 4, and a limiting hole corresponding to the position and size of the through hole on the same side of the outer wall of the air inlet pipe 4 is provided on the circumferential outer wall of the air vent pipe 3. The limiting rod 65 passes through the through hole on the same side of the outer wall of the air inlet pipe 4 and is slidably connected with the limiting hole on the same side of the outer wall of the air vent pipe 3, which can smoothly limit the air inlet pipe 4 and then limit the burner body 5.

[0031] Furthermore, the material of the outer layer 51 is a nickel-based alloy, the high-temperature resistant layer 52 is welded and fixed on the inner wall of the outer layer 51, and the material of the high-temperature resistant layer 52 is high-temperature resistant stainless steel, which can enable the entire burner body 5 to have a good heat storage function, thereby reducing heat loss.

[0032] Specifically, sealing rings are provided at the contact parts of the connecting pipe 1, the gas pipe 2 and the ventilation pipe 3, and sealing rings are also provided at the contact parts of the air inlet pipe 4, the ventilation pipe 3 and the burner body 5, which can make the sealing of the whole device better and prevent the leakage of gas during the transportation process.

[0033] It is worth noting that a fixing column 68 is coaxially fixed to a side surface of the rotating drum 62 away from the air intake pipe 4, a turntable 69 is coaxially fixed to a side surface of the fixing column 68 away from the air intake pipe 4, and a shifting column 610 is fixed near the edge of a side surface of the turntable 69 away from the air intake pipe 4, thereby facilitating driving the rotating drum 62 to rotate.

[0034] It should be noted that the longitudinal sectional shape of the guiding groove on the bottom surface of the transverse plate end of the vertical plate 61 is convex, and the shape of the guiding block 67 is convex and adapted to the shape of the guiding groove on the bottom surface of the transverse plate end of the vertical plate 61, which can make the connection between the guiding block 67 and the guiding groove on the bottom surface of the transverse plate end of the same-side vertical plate 61 closer, and indirectly make the limiting rod 65 more stable during movement.

[0035] Among them, the gas pipe 2 involved in this embodiment is a prior art, and its structure and working principle are as well-known to those skilled in the art, so it will not be elaborated here.

[0036] During the specific use of this embodiment, when it is necessary to disassemble the intake pipe 4 and the burner body 5, first rotate the two turntables 69 through the two dial posts 610. The rotation of the turntable 69 drives the rotation of the same-side fixed column 68 coaxially fixed thereto. The rotation of the fixed column 68 drives the rotation of the same-side rotating cylinder 62 coaxially fixed thereto. The rotation of the rotating cylinder 62 drives the movement of the screw rod 63 threadedly connected thereto. The screw rod 63 moves under the guiding action of the same-side moving column 64, the same-side moving rod 66, the same-side guiding block 67 and the guiding groove on the bottom surface of the transverse plate end of the same-side vertical plate 61, so that the screw rod 63 moves horizontally away from the intake pipe 4. The movement of the intake pipe 4 drives the movement of the same-side moving column 64 fixed thereto. The movement of the moving column 64 drives the movement of the same-side limiting rod 65 fixed thereto. When the limiting rod 65 is completely separated from the same-side limiting hole on the outer wall of the ventilation pipe 3 and the same-side through hole on the outer wall of the intake pipe 4, stop rotating the two dial posts 610, and then the intake pipe 4 and the burner body 5 can be separated from the ventilation pipe 3. According to the above description, conversely, the new intake pipe 4 and the burner body 5 can also be installed.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and do not limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
