Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, and more specifically, it relates to a winter heat preservation and heating device for greenhouses. Background Technology

[0002] With the advent of high molecular polymers such as polyvinyl chloride (PVC) and polyethylene (PE), plastic films have become widely used in agriculture. Greenhouses, originally specialized equipment for vegetable production, have seen increasingly wider applications with the development of production. Currently, greenhouses are used for potted flowers and cut flowers, fruit tree production for cultivating grapes, strawberries, watermelons, melons, peaches, and citrus fruits, forestry production for seedling cultivation and ornamental tree cultivation, and animal husbandry for raising silkworms, chickens, cattle, pigs, fish, and fish fry.

[0003] The heater is designed to address the heating needs of residential and engineering applications in cold regions during winter. Fuel is burned inside an inner combustion chamber, which is then covered by an outer casing. A heat exchange chamber is formed between the inner and outer casing walls. However, existing devices lack a cleaning mechanism, leading to blockage of the air inlet after prolonged use, affecting air intake efficiency and consequently impacting the greenhouse heating effect. To solve these problems, we have introduced the following device. Utility Model Content
