Easy folding water pipe device

A folding water pipe device, comprising:

• an inner tube made of elastic material, and the inner tube has a hollow interior;
• an outer tube wrapping around an outer circumference of the inner tube, wherein the outer tube consists of a first wrapping portion and a second wrapping portion, the first wrapping portion and the second wrapping portion are directly connected to each other along a radial direction of the outer tube, and the first wrapping portion and the second wrapping portion have different modulus of elasticities;
• and
• a connector structure having a first connector and a second connector, wherein the first connector connects to one end of the inner tube and the outer tube, and the second connector connects to the other end of the inner tube and the outer tube;
• wherein when the water pipe device is stretched by an external force, the first wrapping portion, the second wrapping portion and the inner tube are stretched simultaneously, and when the external force is released, the first wrapping portion is in a contracted state, causing the outer tube and the inner tube to wind regularly, and an actual length of the second wrapping portion is greater than an actual length of the first wrapping portion.
