Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Referring to fig. 1 to 3, the gas heating burner with the double ignition needles comprises a burner body 10, wherein the burner body 10 is hollow, an upper opening is formed in the upper end of the burner body 10, a ceramic plate 150 is arranged at the upper opening of the burner body 10, fire outlets 151 are uniformly distributed on the ceramic plate 150, an air inlet pipe 110 is communicated with the left side of the burner body 10, a first ignition needle 140 is arranged on the right side of the burner body 10, and a second ignition needle 120 is arranged on the front side or the rear side of the burner body 10. That is, the ignition range can be effectively enlarged through the first ignition needle and the second ignition needle, so that the ignition rate of the furnace end is improved. Simple structure, convenience and practicality, and meets the use requirement.

In the present invention, one side of the first ignition needle 140 or the second ignition needle 120 is provided with an ODS oxygen deficiency protection device 130. Namely, one of the ODS oxygen deficiency protection devices is mainly responsible for igniting the ODS oxygen deficiency protection device 130 to realize oxygen detection protection, and the other one is mainly used for igniting the burner, so that the ignition efficiency can be ensured, and the use requirements can be met.

In the present invention, the ODS oxygen deficiency protection device 130 is disposed on one side of the first ignition pin 140. By disposing the ODS oxygen deficiency protection device 130 together with the first ignition needle 140, that is, at the opposite side of the intake pipe 110. When oxygen is reduced to cause flameout, the ODS hypoxic guard 130 is the first to sense, and the fast guard signals.

Also included are a gas delivery device 20 and a control device for controlling the ignition needle.

The gas conveying device 20 comprises a three-way pipe 200, the three-way pipe 200 is provided with an air inlet end and two air outlet ends, the two air outlet ends are respectively connected with the ODS oxygen deficiency protection device 130 and the air inlet pipe 110 through pipes, a valve 210 is installed on the air inlet end of the three-way pipe 200 and is connected with an external gas pipe, and the ODS oxygen deficiency protection device 130 is electrically connected with the valve 210 and is used for controlling the valve 210 to be closed. That is, the gas is delivered into the burner and the ODS oxygen depletion protective device 130, respectively, by opening the valve 210. The fuel gas is delivered into the ODS oxygen-deficient protection device 130 and ignited through the first ignition needle, and when oxygen is lacked to cause flameout, the ODS oxygen-deficient protection device 130 sends a signal to control the valve 210 to be closed, so that misfire protection is formed.
