Description
Technical Field
[0001] The utility model relates to the technical field of gas burner heads, in particular to a burner head drainage device and a burner head thereof. Background Art
[0002] The ignition point of the fully premixed commercial gas burner is in the middle of the stove. The air and gas are mixed in the wind cavity before entering the middle of the stove for ignition and combustion.
[0003] At present, in the actual use of the above-mentioned existing fully premixed commercial gas burners, a large amount of soup and water will fall into the burner, that is, the combustion chamber, during cooking. In order to avoid water accumulation and affect the combustion of the burner, most of the burners are provided with a drain for draining water outward. However, since the drain is connected to the combustion chamber, the pot will be constantly lifted and put down during cooking, and the air pressure in the burner will be squeezed, but there is a flame in the combustion chamber, so when the air pressure is squeezed, the flame will rush in and be discharged from the drain, which will reduce the heat of the burner, and there is a safety hazard when the flame is discharged outward. Utility Model Content
[0004] In order to overcome the defects of the prior art, the utility model provides a burner head drainage device and a burner head thereof, aiming to solve the above problems.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a stove head drainage device, including an air inlet pipe, one end of the air inlet pipe is connected to a drainage pipe, an air outlet section located inside the drainage pipe is arranged on the end face of the one end of the air inlet pipe, the side of the air outlet section has an air outlet gap to form an air outlet area outside the air outlet section, and a plurality of drainage holes are opened on the outer wall of the drainage pipe, and the drainage holes are located in the air outlet area.
[0006] The beneficial effect of the utility model is that wind is input from one end of the air inlet pipe and output from the air outlet gap of the air outlet section. Since the drainage hole is located in the air outlet area, the outgoing wind causes air pressure interference to the flame that rushes from the combustion chamber to the drainage pipe, so that the flame will not rush out from the air inlet pipe or the drainage hole, preventing the heat of the burner from being reduced, and effectively eliminating the safety hazards caused by the flame being discharged outward.
[0007] Furthermore, a connecting section is provided at one end of the air inlet pipe near the drain pipe, the air outlet section is installed on the connecting section, a drainage section is provided at one end of the drain pipe near the connecting section, a plurality of drainage holes are provided on the outer wall of the drainage section, the connecting section and the drainage section are detachably provided, and the drainage section is connected to the drain pipe.
[0008] After adopting the above-mentioned further structure, the drain pipe can be installed on the air inlet pipe through the connecting section. Due to the separate structure, it can be easily disassembled and assembled, and the edges can be cleaned. At the same time, the drainage hole is set on the drainage section to further improve the drainage efficiency.
[0009] Furthermore, the air outlet section includes a guide plate arranged on the connecting section, and there are at least four guide plates, at least four of which are distributed along the circumferential direction of the connecting section, and at least four of which do not contact each other and form the air outlet gap, and the air outlet gap is connected to the air inlet pipe.
[0010] After adopting the above-mentioned further structure, the air outlet gap can continuously discharge air, so that the air flow is output from the drain pipe to prevent the flame from entering. Moreover, when the drain pipe is draining water, the water can play a guiding role under the action of the guide plate.
[0011] Furthermore, the guide plate is an arc-shaped plate, and teeth are provided on both side edges of the guide plate.
[0012] After adopting the above-mentioned further structure, the arc-shaped guide plate can better guide the water flow, and because there will be wind output from the air outlet gap, the water entering from the air outlet gap is reduced. At the same time, after the air is discharged from the air outlet gap, when the air flows in the drain pipe, under the action of the teeth, the air in the drain pipe is prone to turbulence, which further prevents the flame from entering the drain pipe and being output from the drain hole.
[0013] Furthermore, the connecting section and the drainage section are threadedly connected.
[0014] After adopting the above-mentioned further structure, the drainage section can be detached from the connecting section for cleaning, which is easy to operate. After water enters the drainage section, the water can be discharged from multiple drainage holes.
[0015] Furthermore, a burner head connecting pipe is provided between the drainage section and the drainage pipe, and an outer wall of the burner head connecting pipe is provided with an external thread.
[0016] After adopting the above further structure, the air inlet pipe and the drain pipe can be conveniently installed on the burner through the burner connecting pipe, and the disassembly and assembly are convenient.
[0017] Furthermore, a limiting ring is provided between the air inlet pipe and the connecting section.
[0018] After adopting the above-mentioned further structure, during the process of installing the drainage section on the connecting section, the position of the drainage section on the connecting section can be limited by the limiting ring to prevent multiple drainage holes from being blocked due to excessive installation.
[0019] The utility model also discloses a burner head, comprising the burner head drainage device mentioned above, the burner head also comprising a furnace shell, the furnace shell is provided with a combustion chamber, the furnace shell is provided with an air chamber, the drainage section is threadedly mounted on the furnace shell so that the drainage pipe extends into the combustion chamber, and the air inlet pipe is located on the outside of the furnace shell.
[0020] The burner head can facilitate installation of the burner head drainage device, so that the drainage pipe is connected to the combustion chamber, thereby facilitating the drainage of water falling into the combustion chamber, and preventing the flame from entering the drainage pipe, thereby preventing the risk of flame leaking out.

[0025] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0026] Combination Figure 1 and Figure 2 A burner drainage device shown in the figure includes an air inlet pipe 1, one end of which is connected to a drainage pipe 9, an air outlet section located inside the drainage pipe 9 is arranged on the end face of one end of the air inlet pipe 1, and an air outlet gap 5 is provided on the side of the air outlet section to form an air outlet area outside the air outlet section, and a plurality of drainage holes 7 are opened on the outer wall of the drainage pipe 9, and the drainage holes 7 are located in the air outlet area; the wind of this embodiment is input from one end of the air inlet pipe 1 and output from the air outlet gap 5 of the air outlet section. Since the drainage holes 7 are located in the air outlet area, the wind that comes out causes air pressure interference to the flame that rushes from the combustion chamber to the drainage pipe 9, so that the flame will not rush out from the air inlet pipe 1 or the drainage hole 7, thereby preventing the heat of the burner from being reduced, and effectively eliminating the safety hazards caused by the flame being discharged outward. The air output by the drainage pipe of this embodiment can also provide secondary air for the combustion of the flame, thereby improving the combustion efficiency.
[0027] Among them, the air inlet pipe 1 of this embodiment is provided with a connecting section 3 at one end close to the drain pipe 9, and the air outlet section is installed on the connecting section 3.
