Description

Technical Field

[0001] This utility model belongs to the field of air pump technology, specifically relating to a full-dimensional foldable portable air pump. Background Technology

[0002] Air pumps are commonly used inflation tools for items such as air mattresses, kayaks, bicycles, balls, and SUP surfboards. However, traditional air pump designs have many limitations. They are mostly rigid, one-piece structures, large in size, and occupy a lot of indoor space when not in use, creating storage problems for users with limited living space. When used outdoors, the bulky and heavy one-piece air pumps not only disrupt the streamlined design of bicycles, increasing wind resistance and riding burden, but are also difficult to store properly in camping backpacks, causing some outdoor enthusiasts to forgo carrying them.

[0003] Most existing folding air pumps only make simple improvements in one dimension, such as folding handles, and cannot reduce size in all aspects. Moreover, the hinge points of the folding handles are prone to failure. In order to ensure the stability of inflation, air pumps often have a base perpendicular to the body, making the air pump in an "I" shape, which is difficult to store and takes up extra space.

[0004] It is evident that existing air pumps cannot meet users' comprehensive needs for portability, ease of storage, and stability of use in different scenarios, and urgently require innovative design to improve them. Utility Model Content
