DETAILED DESCRIPTION OF THE INVENTION

[0031] The present invention is described below in detail in combination with the specific embodiments in the attached drawings.

[0032] FIG. 1, FIG. 2, and FIG. 3 show Embodiment 1 of the elastic hollow breathable massaging burden-reducing backpack. From the drawings, two flexible straps 2 are arranged on the front surface of the backpack 1 in a bilateral symmetrical manner totally, the upper end of each strap is connected to the upper part of the front surface of the backpack through a rubber band 3, and the lower end of each strap penetrates through the corresponding strap buckle 4 arranged at the lower part of the front surface of the backpack 1 and then is fixed.

[0033] Referring to FIG. 3, each strap 2 is provided with an elastic auxiliary strap 5, the two ends of which are fixed to the corresponding strap at a certain interval, so that each auxiliary elastic strap is shorter than the corresponding strap between the two fixed ends of each auxiliary elastic strap when not being stressed and can be stretched to exceed the corresponding strap between the two fixed ends of the auxiliary elastic strap when being stressed. The auxiliary elastic straps 5 are arranged on the inner sides of the straps 2 respectively.

[0034] Massage pads 6 with convex massage nails are arranged on the inner sides, in contact with human shoulders, on the upper parts of the straps 2 respectively and are made of an elastic high-density EVA material, and the protruding height of each massage nail of each massage pad is 2.5 cm.

[0035] Referring to FIG. 1 and FIG. 2, a quadrangular groove 7 is formed in the middle part of the front surface of the backpack 1, with the effect of protecting the spine realized. An opening formed in the upper end of the groove 7 communicates with the atmosphere and is covered by a layer of a ventilation net, so that the heat dissipation effect is exerted; and the groove has a depth of 2.5 cm. The bottom edge of the groove is parallel to the bottom edge of the backpack, and the two vertical edges are symmetrically inward concave arcs.

[0036] Embodiment 2 shown in FIG. 4 differs from Embodiment 1 described above only in that there is no groove in the middle part of the front surface of the backpack 1.
