Description

Technical Field

[0001] The utility model belongs to the technical field of ironing machines, and in particular relates to a low-temperature handheld ironing machine. Background Art

[0002] Steam ironing machines, as a popular and convenient household ironing tool, are designed to efficiently iron clothes while they are hanging naturally, without the aid of an ironing board. They are easy to operate and produce remarkable results. However, most steam ironing machines currently on the market use 100°C high-temperature steam generated by boiling water for ironing. Although this method is effective in most cases, it also faces a limitation that cannot be ignored: for clothes made of specific materials, such as delicate cashmere, fine velvet, soft rabbit hair, and mohair, directly using 100°C steam to iron may cause a series of problems. These problems include but are not limited to the shrinkage of clothing fibers, the formation of knots, and the loss of the original fluffiness of the clothes. These problems not only affect the comfort and aesthetics of wearing, but may also directly damage the quality of the clothes and cause irreversible damage. Utility Model Content
