Problems solved by technology

Since a through hole is set in the center of the burner, there are seams in the stamping and welding structure, and there is a relatively large chance of air leakage due to thermal expansion, contraction, and humidity. The area is reduced, on the other hand, it will also greatly affect the life of the combustion board, especially the inner hole of the cordierite honeycomb board, which is easy to be damaged
The damaged combustion board cannot burn normally, and tempering may cause fire and other safety accidents
Furthermore, installing the flameout protection device at the center of the burner's combustion plate is one of the inconveniences of installation. During use, it is in a high-temperature environment for a long time, and the flameout protection device body and connecting wires are prone to aging and leakage, which makes the burner Unable to properly fire and use

Embodiment 1

[0020] Embodiment one: if Figure 2 ~ Figure 4 As shown, the gas burner of this embodiment is mainly composed of a burner body 1, an outer gas mixing chamber 3, an inner gas mixing chamber 4, an injection pipe 21 leading to the outer gas mixing chamber 3, and a Through the side wall of the burner body 1, the partition 9 between the outer gas mixing chamber 3 and the inner gas mixing chamber 4 leads to the injection pipe 22 of the inner gas mixing chamber 4, located in the outer gas mixing chamber The combustion plate 5 and the ignition device 6 and the flameout protection device 7 above the chamber 3 and the internal gas mixing chamber 4 can be designed as an integrated structure or as a split structure. The inner gas mixing chamber 4 is provided with a channel 8, which passes through the partition 9 between the outer gas mixing chamber 3 and the inner gas mixing chamber 4 to the inner side of the outer wall of the burner body 1, and the channel The exhaust part of 8 is in co...

Embodiment 2

[0021] Embodiment two: if Figure 5 As shown, its main structure is the same as that of Embodiment 1, the difference is that the channel 8 is a pipe, one end communicates with the inner gas mixing chamber 4, and the other end passes through the partition 9 to reach the outside of the outer gas mixing chamber 3 Pass through the burning plate 5 upwards.

Embodiment 3

[0022] Embodiment three: as Figure 6 As shown, its main structure is the same as that of Embodiment 1, the difference is that in order to improve the ignition efficiency and safety protection performance, there are two passages 8, and the ends of the passages 8 are distributed at different positions on the inner wall of the burner body 1.

Abstract

The invention relates to a gas burner which comprises a burner body, an outer gas mixing chamber, an inner gas mixing chamber, two ejecting pipes, a burning board, an ignition device and a flame-out protection device, wherein one ejecting pipe leads to the outer gas mixing chamber, and the other ejecting pipe penetrates through the side wall of the burner body and a partition board between the outer gas mixing chamber and the inner gas mixing chamber and leads to the inner gas mixing chamber; the burning board is positioned above the outer gas mixing chamber and the inner gas mixing chamber; the inner gas mixing chamber is provided with a channel which penetrates through the partition board between the outer gas mixing chamber and the inner gas mixing chamber and leads to the inner side of the outer side wall of the burner body, and an exhausting part of the channel is in contact with the burning board through a heat-resistant sealing piece to realize the sealing isolation with the outer gas mixing chamber; the ignition device and the flame-out protection device are mounted on the outer side wall of the burner body, and an ignition needle and a probe extend above the burning board at the external part of the channel. According to the gas burner adopting the structure, the flame-out protection device is not positioned in the central high-temperature environment, so that the service life is long.

Description

technical field [0001] The invention belongs to the technical field of manufacturing gas burners for gas stoves, heaters or industrial and commercial drying equipment, and in particular relates to a gas burner. Background technique [0002] Such as figure 1 As shown, the gas burner in the prior art is mainly composed of a burner body 1, an injection pipe 2, an outer gas mixing chamber, an inner gas mixing chamber, an outer gas mixing chamber and an inner gas mixing chamber. The combustion plate 5 above the chamber, the ignition device 6, and the flameout protection device 7 are composed, and the high-temperature gas burner equipped with the flameout protection device 7 is usually installed in the center of the burner and made with a hole in the structure. Since a through hole is set in the center of the burner, there are seams in the stamping and welding structure, and there is a relatively large chance of air leakage due to thermal expansion, contraction, and humidity. On...
