Technical Field

[0001] The utility model belongs to the technical field of heating equipment, and specifically relates to a novel fuel ignition integrated heating controller. Background Art

[0002] Heaters are mainly devices that use fuel oil as fuel to generate heat and are used to keep warm. The heater is light, flexible, small, light, powerful, easy to operate, safe and reliable, uses less electricity, and consumes less fuel. Heaters are divided into two types: industrial and household. The most common is in the industrial field. In the industrial field, it is mainly used to heat some industrial and commercial places and some large spaces such as buildings and bridges. It can also be used for heating animal husbandry in cold areas. As the name suggests, it is to heat the air.

[0003] Among various heating methods, air heating is relatively comfortable. It heats the entire space with uniform temperature. It has the advantages of rapid heating and fast heat flow. For practical and safety reasons, traditional heaters usually have flame photosensitive probes for detecting flames. However, flame photosensitive probes are usually directly located in open flames when in use, resulting in a short service life and easy danger after failure. Summary of the invention
