Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, and particularly relates to an ignition device. Background Art

[0002] At present, internal combustion burners are used more and more widely, but their disadvantages are also obvious. Although an extinguishing protection device is provided, its action is not sensitive enough to achieve the purpose of safety protection. The national standard for the extinguishing protection device of commercial cooking stoves requires that when the pilot flame goes out, the main flame should also go out immediately. In the existing internal combustion burner with a pilot flame, the pilot flame is set at the combustion chamber part in the center of the burner. If the flameout protection needle is set too short, the flameout protection needle cannot detect high temperature, and the pilot flame itself goes out; if the flameout protection needle is set too long, the main flame will burn to the flameout protection needle, and when the pilot flame goes out, its main flame still burns (as Figure 8 ). Therefore, simply changing the length of the flameout protection needle cannot achieve the purpose of safety protection. Content of the Utility Model

[0028] Referring to Figure 1-8 , an ignition device includes a vertically arranged main body 2. An ignition needle 3 penetrates through the inside of the main body 2. A mixing pipe 5 and a flameout protection needle 4 are also arranged inside the main body 2. The flameout protection needle 4 penetrates through the inside of the main body 2. The top end of the flameout protection needle 4 bends horizontally, and after bending, it forms an annular structure. The shape of the annular structure 41 can be a circular annular structure, or an elliptical annular structure, or a polygonal annular structure. This annular structure surrounds the top end of the mixing pipe 5. A burner cap 1 is arranged at the top of the main body 2. The burner cap 1 encloses the top ends of the flameout protection needle 4 and the ignition needle 3. At least one flame outlet 12 that is internally and externally connected is arranged on the surface of the burner cap 1. The shape of the flame outlet 12 can be circular, or elliptical, or polygonal. The top end of the ignition needle 3 is higher than the top end of the main body 2. The ignition needle 3 is arranged below the annular structure.

[0029] The top of the mixing pipe 5 is higher than the top of the main body 2, and the top of the flameout protection needle 4 is higher than the top of the mixing pipe 5. The flameout protection needle is arranged above the mixing pipe and is used to detect the upward-burning flame.

[0030] A flange 6 is arranged around the top of the main body 2, and the burner cap 1 is fixed to the outside of the flange 6. The flange is used to fix it in the hole of the combustion device.

[0031] A tee 7 is fixedly installed at the bottom of the mixing pipe 5, and one end of the tee 7 communicates with the inside of the mixing pipe 5. The other two ends of the tee are respectively supplied with air and gas.
