Abstract:
A remote sensing fresh air adjustable system and a knapsack applying same. An air blowing system has three gears (high, middle, and bottom) of air quantity, and air speed is adjusted by a remote controller, so that the back is cool, light, comfortable, and not easy to sweat. A butterfly buckle (3) has an opening and closing elastic function, and the width of two shoulder straps can be automatically adjusted to fit the neck size of fat and thin bodies; moreover, more than 180-degree space movement is provided, so that the neck is more comfortable and fits the shoulders, and the shoulder straps do not droop towards the arms on two sides while the neck is not pressed. In addition, due to a forward inclination function of the buckle, the inclination that best fits the back can be made according to human engineering. The fresh air adjustable system and the knapsack applying same are simple in structure, convenient and practical, and have a good application prospect.
