Description

Technical Field

[0001] This utility model relates to the field of heating elements for small electrical appliances, specifically to a heating element for a small iron. Background Technology

[0002] Small irons (such as handheld garment steamers and mini travel irons) are widely used for spot ironing at home or for travel due to their small size and portability. The heating element is the core component of a small iron; its heat distribution uniformity, heat dissipation efficiency, and compact structure directly affect the ironing effect and the product's portability. Currently, most small irons have flat heating elements, typically measuring 150*50*3mm, which are relatively large. These heating elements have a power of 500W-700W, with the heating area concentrated in the center and insufficient heating at the edges, resulting in uneven temperature distribution on the iron's bottom surface. Therefore, this paper proposes a new heating element for small irons to address these issues. Utility Model Content
