[0020] The present invention provides a high-strength water hose made of polyester fiber. Figure 1-3 As shown, it includes a water hose inner layer 11, a water hose middle layer 12, a water hose outer layer 13, a first gap 14, a second gap 15, an elastic pad 16, a first groove 17, a second groove 18, and a water injection channel 19.

[0021] like Figure 1-3 As shown, the water hose inner layer 11, the water hose middle layer 12 and the water hose outer layer 13 are all made of polyester fiber, a first gap 14 is provided between the water hose inner layer 11 and the water hose middle layer 12, a second gap 15 is provided between the water hose middle layer 12 and the water hose outer layer 13, and elastic pads 16 are provided in the first gap 14 and the second gap 15. The elastic pads 16 in the first gap 14 are fixedly connected to the outer circular surface of the water hose inner layer 11, and the elastic pads 16 in the second gap 15 are fixedly connected to the outer circular surface of the water hose middle layer 12. A water injection channel 19 is opened in the water hose inner layer 11.

[0022] The outer circumference of the hose inner layer 11 is provided with a plurality of first grooves 17, and the outer circumference of the hose intermediate layer 12 is provided with a plurality of second grooves 18. The hose inner layer 11 is blended with spandex fibers, and the inner circumference of the hose inner layer 11 is coated with a fluorocarbon resin coating. Both the hose intermediate layer 12 and the hose outer layer 13 are treated with a CFL solution. The width of the second grooves 18 is greater than the width of the first grooves 17. The second grooves 18 and the first grooves 17 are provided on the hose inner layer 11 and the hose intermediate layer 12, respectively, with equal arcs.

[0023] It is worth noting that the ratio of spandex fiber to polyester fiber in the inner layer 11 of the water hose is less than 1:5, the thickness of the inner layer 11 of the water hose, the middle layer 12 of the water hose and the outer layer 13 of the water hose are equal, and the elastic pad 16 is made of rubber material.

[0024] When the water hose is filled with water, the water pressure in the inner layer 11 of the water hose increases, and the inner circular surface of the inner layer 11 of the water hose is subjected to high water pressure, thereby causing the inner layer 11 of the water hose to expand. The first groove 17 ensures that the cross-sectional area of ​​the inner circular surface of the inner layer 11 of the water hose expands, and then the inner layer 11 of the water hose compresses the elastic pad 16 in the first gap 14, and the elastic pad 16 generates elastic potential energy for the middle layer 12 of the water hose, thereby pushing the middle layer 12 of the water hose to expand outward. The second groove 18 ensures that the cross-sectional area of ​​the inner circular surface of the middle layer 12 of the water hose expands. Finally, the middle layer 12 of the water hose compresses the elastic pad 16 in the second gap 15, and the elastic pad 16 generates elastic potential energy for the outer layer 13 of the water hose, thereby pushing the outer layer 13 of the water hose to expand outward, thereby ensuring the expansibility and strength of the water hose.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
