Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of ignition needle, specifically relates to an infrared heating plate ignition needle. BACKGROUND

[0002] The infrared heating plate ignition needle is a specially designed device for igniting an infrared heating plate. This ignition needle is commonly used in industrial heating equipment, such as infrared heaters or ovens, and its working principle is to generate high temperature through electric heating to ignite the fuel on the heating plate or start the heating element.

[0003] In the prior art document with the publication number CN201721700241.2, an ignition needle is proposed, which has a conductive part connected to the ground needle circuit. When the ignition needle is installed in the furnace head, the conductive part contacts the metal furnace head, and the ground needle is connected to the ground, allowing the ground needle to achieve double grounding. When igniting, even if there is no flame between the probe and the ground needle due to insufficient gas, a loop cannot be formed, and a flame exists between the probe and the inner wall of the furnace head, forming a loop with the conductive part, and the detection line outputs a signal indicating successful ignition, ensuring the accuracy of the probe. In addition, since the length of the ground needle is shorter than that of the probe, when the fire enters the furnace head, the fire near the ground needle can be ignited, avoiding the explosion caused by the excessive ignition of the fire, and ensuring the normal operation of the furnace head.

[0004] In actual operation, the infrared heating plate has many deficiencies in ignition, such as low success rate of electronic ignition or manual ignition, frequent ignition attempts not only reduce work efficiency, but also shorten the service life of the equipment. In addition, these ignition methods may have safety hazards, such as sparks flying or high temperature accidents, increasing the risk in the use process. When it is raining, if it needs to be used, the operation feasibility is low. Therefore, an infrared heating plate ignition needle is proposed. UTILITY MODEL CONTENTS
