[0024] As Figs. 1 to 3 In combination with the shown, a breathable backpack includes a backpack body, the backpack body includes a front width 1, a back width 2 and a side width 3, the top end of the side width 3 is sewn with two shoulder straps 4, characterized in that the backpack body further includes a breathable device 5, one end of the breathable device 5 is arranged on the back width 2, the other end of the breathable device passes through the back width 2 and is connected with the shoulder strap 4.
[0025] The breathable device is applied to the back width and shoulder strap part of the backpack, and forms an air flow space through the ventilation chamber. In the embodiment, the breathable device plays multiple roles in the breathable backpack, such as improving air circulation, reducing pressure, perspiration and moisture, and improving stability, which is a key design to improve the comfort and practicality of the backpack.
[0026] The breathable device 5 includes a first chamber 6 and a second chamber 7, the first chamber is a closed single-port chamber for limiting gas flow, and the first chamber 6 is independent of the second chamber 7 and is not connected.
[0027] The first chamber and the second chamber form separate ventilation chambers. The first chamber provides the role of a breathable passage in the embodiment, and the second chamber can adjust the carrying adaptability according to the carrying experience in the embodiment, and improve the comfort of use.
[0028] In the embodiment, the first chamber 6 includes a breathable hole 8 forming a breathable passage, a breathable cavity 9 and a gas control chamber 10 in sequence, the breathable hole 8 is two middle hollow air holes 8, and the breathable hole 8 is arranged on both sides of the oval-shaped breathable cavity 9.
[0029] In the embodiment, the gas control chamber 10 is a gradually expanding closed chamber with one-way opening of the breathable hole 8.
[0030] Gas can flow in from the gas permeable hole, through the gas permeable cavity, and then into the gas control chamber from the gas permeable hole. Because the gas control chamber is a gradually expanding closed chamber, gas also flows out from the gas permeable hole, thereby achieving the effect of gas circulation.
[0031] In the embodiment, the second chamber 7 is semi-enclosed with respect to the first chamber 6, and sequentially comprises a flow line 11, a flow chamber 12, and a flow pipe 13. The flow line 11 is in a curved shape and is arranged at the rear panel 2. The flow chamber 12 is arranged at the innermost side of the rear panel 2.
[0032] The position design of the first chamber with respect to the second chamber is beneficial to reducing the size of the gas permeable device in the backpack and reducing the load of the backpack.
[0033] In the embodiment, the flow pipe 13 is arranged on the shoulder strap 4, and the end of the flow pipe 13 is provided with an exhaust port 14 and an inflation port 15. The inflation port 15 is used to inflate the gas in the second chamber 7 by pressing to form gas.
[0034] The technical feature realizes the adjustability of the supporting force of the shoulder strap through the cooperation of the flow pipe 13, the exhaust port 14, and the inflation port 15, improves the air permeability and comfort, enhances the functionality of the backpack, and significantly improves the user experience, especially suitable for scenarios that need to be carried for a long time.
[0035] In the embodiment, the exhaust port 14 is provided with an exhaust valve 16, and the exhaust valve 16 is used to discharge the gas in the second chamber 7.
[0036] When the gas in the second chamber is too saturated, the exhaust valve can be used to reduce the gas content in the second chamber.
[0037] In the embodiment, the shoulder strap comprises a limiting belt 17, which is sewn at the end of the flow pipe to limit the movement range of the flow pipe 13. The limiting belt is used to prevent the movement of the flow pipe during use.
[0038] In the embodiment, the rear panel 2 further comprises a bulging area 18 and a recessed area 19. The gas permeable device 5 is arranged in the bulging area 18 of the rear panel 2. The bulging area 18 and the recessed area 19 are sewn with an arc-shaped hollow hem bar 20 along the edge portion. The hollow hem bar 20 is made of elastic material, such as silicone or rubber.
[0039] The bulging area and the recessed area provide a concave-convex contact surface for the back in the embodiment, thereby reducing the contact surface of the back with the rear panel of the backpack, reducing the proportion of sweat generation, and providing a breathable and comfortable carrying environment.
[0040] In the embodiment, the back width 2 further comprises a breathable contact area 21, which is set 0.5 cm higher than the groove area 19 and is made of mesh fabric.
[0041] The mesh structure promotes air circulation, reduces the hot and stuffy feeling of the back, keeps the back dry and comfortable, and prolongs the service life of the breathable contact area.
[0042] In the embodiment, the back width 2 is made of breathable fiber, and the shoulder strap is provided with a breathable ring 22.
[0043] Compared with the prior art, the breathable device is applied to the back width and the shoulder strap of the backpack, and forms an air flow space through the ventilation chamber. In particular, the combination of the first chamber and the second chamber plays multiple roles in improving air circulation, reducing pressure, perspiration and moisture removal, and improving stability in the breathable backpack. It is the key to improving the comfort and practicality of the backpack.
[0044] In the case of no conflict, the above embodiments and features in the embodiments can be combined with each other.
[0045] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, and are not limited to the protection scope of the utility model.
