Description

Technical Field

[0001] The utility model relates to the technical field of air outlet structures, in particular to an air outlet structure for a heater. Background Art

[0002] A heater is a device that uses energy such as electricity or fuel to heat the air through a heating element and then blows the hot air out with a fan. The heater has the characteristics of fast heating speed, easy use, and flexible mobility. It is one of the commonly used heating devices for winter heating and temporary heating scenarios.

[0003] Common heaters generally use a fan to draw air into the combustion chamber and discharge the gas through the air outlet structure. The air outlet structure guides the exhaust gas generated by combustion to the smoke exhaust system through a heat exchanger, thereby separating the exhaust gas from the hot air, and using filters and catalytic converters to separate harmful substances in the exhaust gas.

[0004] After filtering harmful substances in exhaust gas for a long time, the surface of the filter and catalytic converter will absorb a large amount of impurities, which will clog the filtering structure of the filter and catalytic converter. However, since the filter and catalytic converter are fixed inside the heater, the heater needs to be turned on to clean the filter and catalytic converter. The interior of the heater is relatively narrow, resulting in poor cleaning effect on the filter and catalytic converter. Utility Model Content
