Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to an upward-inlet burner. Background Technology

[0002] "Top air intake" refers to the air mixed during combustion entering from the top of the stove panel, and its characteristic is that it is not affected by the stove panel.

[0003] For example, patent CN218178884U discloses an anti-dry-burning top-intake burner, including a base, a burner head, a distributor seat, a central annular flame cap, an outer annular flame cap, and a telescopic temperature probe. The burner head is fastened to the base. The central nozzle seat, left nozzle seat, and right nozzle seat support the top plate of the burner head seat and are respectively opposite to the central ejector tube, the left outer ejector tube, and the right outer ejector tube. The burner head supports the distributor seat. The left axial gas hole and the right axial gas hole are connected to the axial gas channel. The central annular flame cap seat is connected to the central annular gas outlet chamber. The central annular flame cap and the outer annular flame cap are fastened to the central annular flame cap seat and the outer annular gas groove, respectively. The rod of the telescopic temperature probe is fixed to the axial through hole, and the telescopic head extends out from the hole on the axis of the central annular flame cap.

[0004] The problem with the existing technology is that when cleaning the burner, the burner head above the panel is usually removed from the base, and the panel surface and burner head are cleaned. When the user reinstalls the burner head back onto the base, it is difficult to observe the bottom of the burner head, making installation difficult. If the burner head is slightly misaligned, the nozzle seat will not be aligned with the injector tube, resulting in reduced combustion efficiency, abnormal flame color, or even failure to ignite normally. In severe cases, it may endanger the user's safety.

[0005] Therefore, this application proposes an upward-inlet burner to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an upper air intake burner that can prevent the burner head from shifting when it is installed.

The nut 53 is screwed onto the upper ends of the thermocouple 51 and the ignition needle 52 and presses the liquid receiving tray 6 tightly.

[0035] During installation, the thermocouple 51 and the ignition needle 52 pass through the base 1 and the liquid receiving tray 6 from bottom to top, and then the liquid receiving tray 6 is pressed tightly by the nut 53. This installation method does not require the use of other screws, and the structure is simple and the installation is quick.

[0036] In a preferred embodiment, the burner head 2 includes a gas distribution plate 7 and a flame cover 9. The injector tube 4 and the through groove 21 are both disposed on the gas distribution plate 7. A gas mixing channel 8 communicating with the injector tube 4 is disposed in the gas distribution plate 7, and the flame cover 9 is disposed above the gas mixing channel 8.

[0037] In Example 1, as referred to Figure 6 The ejector tube 4 includes two outer ring ejector tubes 41 and one central ejector tube 42. The nozzle 3 includes two outer ring nozzles 31 and one central nozzle 32, which are respectively opposite to the outer ring ejector tubes 41 and the central ejector tube 42.

The outer ring ejector tubes 41 are connected to the outer ring mixing channel 82, and the central mixing channel 81 is connected to the central ejector tube 42. The flame cap 9 includes an outer ring flame cap 91 and a central flame cap 92. The outer ring flame cap 91 is placed over the outer ring mixing channel 82, and the central flame cap 92 is placed over the central ejector tube 42.

[0038] In a preferred embodiment, the central ejector tube 42 is disposed between the two outer ring ejector tubes 41, and the central ejector tube 42 and the outer ring ejector tubes 41 have the same orientation.

[0039] In Example 2, as referred to Figure 7 The number of ejector tube 4 and nozzle 3 is 1. The gas mixing channel 8 includes a central gas mixing channel 81 and an outer ring gas mixing channel 82. The outer ring gas mixing channel 82 is connected to the ejector tube 4 and the central gas mixing channel 81. The flame cap 9 includes an outer ring flame cap 91 and a central flame cap 92. The outer ring flame cap 91 covers the outer ring gas mixing channel 82, and the central flame cap 92 covers the central gas mixing channel 81.
