Description

Technical Field

[0001] This utility model relates to a burner. Background Technology

[0002] Patent CN216047842U discloses an outdoor burner, including a combustion tube, a transparent tube, and a feeding tube. The transparent tube is detachably installed on the combustion tube, and the feeding tube is installed on the side wall of the combustion tube and connected to it. An inclined air inlet mesh is provided at the bottom of the feeding tube, with its end extending into the combustion tube to form the base plate of the combustion tube. In use, fuel is placed in the combustion tube and ignited. Excess fuel is loaded into the feeding tube. Both the fuel in the combustion tube and the fuel in the feeding tube fall onto the air inlet mesh. The holes in the air inlet mesh replenish the oxygen needed for fuel combustion, thus preventing the fuel from extinguishing. Under the influence of gravity, the fuel in the feeding tube continuously falls onto the air inlet mesh and rolls down along it into the combustion tube, providing automatic fuel replenishment.

[0003] It has the following shortcomings: the diameter of the air intake hole is fixed, which results in a relatively fixed amount of oxygen during combustion, making the combustion intensity of the combustion tube completely uncontrollable. Moreover, the uncontrollable combustion intensity of the combustion tube leads to a highly uncertain and unadjustable combustion flame in the transparent tube. Utility Model Content

[0004] The purpose of this invention is to provide an improved burner that allows for adjustment of the combustion heat of the combustion tube.

[0005] The purpose of this utility model is achieved as follows.

[0006] An improved burner includes a combustion tube, a feed tube, a flame tube, and a perforated plate. The flame tube is located at the upper end of the combustion tube, and the bottoms of the combustion tube and the feed tube are connected. The perforated plate forms the bottom of the combustion tube and the feed tube, and the mesh openings slope downwards from the feed tube towards the combustion tube. A chamber is provided below the perforated plate, and a dust collection box is provided at the bottom of the chamber. An air inlet is provided on the side wall of the chamber, and a movable damper is provided on the side wall of the chamber corresponding to the air inlet. The damper has a connecting hole. Adjusting the damper allows at least part of the air inlet and the connecting hole to be aligned and overlapped. The combustion tube is connected to the outside through the chamber, the air inlet, and the connecting hole.

[0007] This utility model adjusts the size of the overlapping portion of the air intake hole and the connecting hole of the damper, thereby controlling the flow rate of oxygen supplied from the outside to the combustion tube and thus controlling the fire intensity inside the combustion tube.

[0008] Furthermore, a heat insulation sleeve is provided outside the combustion tube. The bottom of the heat insulation sleeve is open, and an air intake channel is left between the heat insulation sleeve and the combustion tube. A support part is provided near the top outer periphery of the combustion tube. A guide ring is provided on the support part. The guide ring is placed inside the heat insulation sleeve near the top. The outer periphery of the guide ring abuts or is close to the inner side wall of the heat insulation sleeve. The bottom of the flame tube sits on the guide ring and is located between the combustion tube and the heat insulation sleeve. An air intake channel connecting the flame tube is left between the inner periphery of the guide ring and the combustion tube.

[0009] The air guide ring controls the airflow into the flame tube through the intake channel, thereby determining the maximum flame height entering the flame tube. In conjunction with the damper, it adjusts the firepower inside the flame tube, thus regulating the flame height within the flame tube.

[0010] Furthermore, the feed pipe is inclined on one side of the combustion pipe, and the feed pipe extends into the flame pipe to form a fixing bracket for vertically fixing the flame pipe.

[0011] Furthermore, the damper is a turntable, with the center of the turntable and the side wall of the chamber connected by a pivot. The connecting hole and the air inlet are both arc-shaped with the pivot as the center, and the turntable is provided with a handle.

[0012] The handle allows for easy rotation of the turntable, thereby adjusting the overlap range between the connecting hole and the air intake hole.

[0013] Furthermore, a limiting part is provided on one side of the turntable corresponding to the connecting hole. The limiting part extends into the air inlet, and the turntable drives the limiting part to move within the air inlet.

[0014] The limiting part restricts the rotation range of the turntable to prevent the turntable from rotating too much.

[0015] Furthermore, the damper is placed inside the chamber, and the side wall of the chamber is provided with an arc-shaped clearance hole corresponding to the handle part, through which the handle part passes.

[0016] The damper features a concealed design, and the curved clearance hole allows the handle to extend into the chamber for user operation.

[0017] Furthermore, the guide ring is circular, which facilitates the placement of the flame tube.

[0018] Furthermore, the guide ring is provided with guide holes. The guide holes increase the air intake of the flame tube, which helps to increase the flame height of the flame tube.

[0019] This utility model relates to an air damper that adjusts the size of the overlapping portion of the air inlet and connecting hole, thereby controlling the flow rate of oxygen supplied to the combustion tube and thus controlling the flame intensity within the combustion tube. A guide ring controls the airflow entering the flame tube through the air intake channel, thereby determining the maximum flame height entering the flame tube. This, combined with the air damper adjustment, regulates the flame intensity within the combustion tube, thus adjusting the flame height. The handle facilitates the rotation of a turntable, adjusting the overlap range of the connecting hole and air inlet. Air damper adjustment is simple and easy to operate. A limiting part restricts the rotation range of the turntable, preventing excessive rotation angle. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1, see Figure 1-4 As shown, an improved burner includes a combustion tube 1, a feed tube 2, a flame tube 3, a perforated plate 4, a heat insulation sleeve 5, and a chamber 6.

[0026] The feed pipe 2 is inclined on one side of the combustion pipe 1. The bottoms of the combustion pipe 1 and the feed pipe 2 are connected. The mesh plate 4 forms the bottom of the combustion pipe 1 and the feed pipe 2, and the mesh is inclined from top to bottom from the feed pipe 2 towards the combustion pipe 1. A chamber 6 is provided below the mesh plate 4. The heat insulation sleeve 5 is fitted onto the combustion pipe 1. The bottom of the heat insulation sleeve 5 is connected and fixed to the chamber 6. The bottom of the heat insulation sleeve 5 is open. An air intake channel 50 is left between the heat insulation sleeve 5 and the combustion pipe 1. A support part 11 is provided near the top outer periphery of the combustion pipe 1. A guide ring 7 is provided on the support part 11. The guide ring 7 is placed inside the heat insulation sleeve 5 near the top. The outer periphery of the guide ring 7 abuts or is close to the inner wall of the heat insulation sleeve 5. The flame tube 3 is provided at the upper end of the combustion pipe 1. Specifically, the bottom of the flame tube 3 sits on the guide ring 7 and is located between the combustion pipe 1 and the heat insulation sleeve 5. An air intake channel 70 connecting the flame tube 3 is left between the inner periphery of the guide ring 7 and the combustion pipe 1. The feed pipe 2 extends into the flame tube 3 and a fixed bracket 21 extends out, which fixes the flame tube 3 vertically.

[0027] Preferably, the guide ring 7 is annular, and several guide holes can be provided on the guide ring 7 to further increase the air intake of the flame tube.

[0028] A dust collection box 61 is provided at the bottom of the chamber 6, and an air inlet 60 is provided on the side wall of the chamber 6. A movable damper 8 is provided on the side wall of the chamber 6 corresponding to the air inlet 60. The damper 8 has a connecting hole 80. By adjusting the damper 8, the air inlet 60 and the connecting hole 80 are at least partially aligned and overlapped. The combustion pipe 1 is connected to the outside through the chamber 6, the air inlet 60 and the connecting hole 80. Specifically, the damper 8 is a turntable. The center of the turntable is rotatably connected to the side wall of the chamber 6 via a pivot. Both the connecting hole 80 and the air inlet 60 are arc-shaped with the pivot as the center. The turntable has a handle 81. A limiting part 82 is provided on the side of the turntable corresponding to the connecting hole 80. The limiting part 82 extends into the air inlet 60. The turntable drives the limiting part 82 to move within the air inlet 60.

[0029] In this embodiment, the damper 8 is placed inside the chamber 6, and the side wall of the chamber 6 is provided with an arc-shaped clearance hole 62 corresponding to the handle part 81, through which the handle part 81 passes.

[0030] Its working principle is as follows: the user adjusts the overlap range between the connecting hole 80 and the air inlet 60 via the handle 81 to control the combustion intensity within the combustion tube 1. The flame from the combustion tube 1 extends upward into the flame tube 3. Outside air enters the flame tube 3 through the air inlet channel 50 and the annular guide-restricted air inlet 70, and this airflow pushes the flame within the flame tube 3 upward. Thus, the user adjusts the flame height within the flame tube 3 by adjusting the damper 8.
