Description

Technical Field

[0001] This utility model relates to the field of backpacks, and more particularly to a breathable backpack back structure. Background Technology

[0002] Backpacks, as a convenient carrying tool, are widely used in various scenarios such as daily commuting, outdoor travel, mountaineering and exploration, and students going to school. One of the core design goals is to improve the user's comfort when carrying the backpack, especially for long periods of time or when carrying a heavy load.

[0003] When users carry a backpack for extended periods, especially during exercise or in hot environments, a relatively enclosed microclimate is formed between the back and the bag. This makes it difficult for the body's heat and sweat to dissipate effectively, leading to heat buildup and sweat-soaked clothing. This not only causes a sticky and stuffy feeling but can also lead to skin allergies and prickly heat in severe cases, greatly reducing the user experience. Traditional backpack ventilation solutions can achieve breathability through more complex structures, but the disadvantages are that the structure is complex, costly, difficult to maintain, and difficult to store. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a breathable backpack back structure, which solves the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a breathable backpack back structure, comprising:

[0006] A breathable back structure is provided on the back of the backpack. The breathable back structure includes a breathable mesh, a breathable fabric, breathable holes, and a breathable layer. The breathable mesh is located on the back of the backpack. A breathable fabric is provided on the inner side of the breathable mesh. Multiple breathable holes are provided on the surface of the breathable fabric. A breathable layer is provided on the inner side of the breathable fabric. The breathable layer is a three-dimensional mesh structure composed of one of the following: polyolefin elastomer, thermoplastic polyester elastomer, polyethylene elastomer, and polypropylene elastomer.

[0007] Preferably, it also includes a disassembly assembly; the disassembly assembly is connected to the back ventilation structure.

[0008] Preferably, the disassembly assembly includes a connecting strap, a zipper, and a zipper pull. The zipper is horizontally disposed on the outer surface of the connecting strap, and the connecting strap is disposed on the upper middle side of the breathable mesh.

[0009] Preferably, the outer surface of the zipper is provided with a zipper pull, and the zipper pull is slidably disposed on the zipper teeth.

[0010] Preferably, the shape of the breathable back structure is a contour that conforms to the back of the backpack.

[0011] Preferably, the two ends of the connecting strap are sewn together to the left and right sides of the back of the backpack, and the upper and lower sides of the connecting strap are separated by breathable mesh.

[0012] Beneficial effects

[0013] This invention provides a breathable back structure for a backpack. Compared with the prior art, it has the following advantages:

[0014] 1. In this utility model, through the designed back ventilation structure, when the user's back sweats, the sweat generated on the user's back will first penetrate the ventilation layer. Because the three-dimensional mesh structure composed of polyolefin elastomer or thermoplastic polyester elastomer, polyethylene elastomer, or polypropylene elastomer has good ventilation and breathability, the sweat that penetrates the ventilation holes will not stagnate on the surface of the ventilation layer, but will quickly diffuse outward through the material of the ventilation layer itself and eventually be discharged outside the backpack, thereby avoiding the accumulation of moisture between the back and the backpack. When the backpack is compressed, the ventilation layer made of the three-dimensional mesh structure composed of polyolefin elastomer, thermoplastic polyester elastomer, polyethylene elastomer, or polypropylene elastomer absorbs and disperses the impact pressure of the backpack on the back with its good elasticity and compression resilience, providing a comfortable shock absorption effect. Even under pressure, the innermost ventilation fabric can still maintain a small gap with the user's back, preventing the ventilation holes from being blocked due to complete contact, and ensuring that the path of sweat discharge is always unobstructed.

[0015] 2. In this utility model, through the designed disassembly component, when the backpack is in normal use, the zipper on the outer surface of the connecting strap is in a closed state, and the internal breathable layer and breathable fabric are securely contained within it. When the user needs to disassemble or replace the core functional layer, first operate the zipper pull to slide it along the zipper teeth. Opening the zipper opens the upper and lower sides of the breathable mesh. At this time, the user can easily remove the entire back breathable structure composed of the breathable layer and breathable fabric for subsequent cleaning, drying, or disinfection, completely solving the problem of traditional backpacks being difficult to clean and prone to bacterial growth.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides two technical solutions, specifically including the following embodiments:

[0024] Example 1:

[0025] A breathable backpack back structure includes: a breathable back structure 1; the breathable back structure 1 is disposed on the back of the backpack 2, and includes a breathable mesh 101, a breathable fabric 102, breathable holes 103, and a breathable layer 104; the breathable mesh 101 is disposed on the back of the backpack 2, the inner side of the breathable mesh 101 is provided with the breathable fabric 102, the surface of the breathable fabric 102 is provided with multiple breathable holes 103, and the inner side of the breathable fabric 102 is provided with the breathable layer 104, the breathable layer 104 is a three-dimensional mesh structure composed of one of polyolefin elastomer, thermoplastic polyester elastomer, polyethylene elastomer, and polypropylene elastomer. It should be noted that any material that meets the conditions and is made into a three-dimensional mesh breathable structure through a specific process can be used on backpacks. The backpack straps, waist, back of the backpack, straps, waist and other parts that come into close contact with the human body can all achieve better breathability and increase carrying comfort through this method.

[0026] When the user sweats during work, the sweat first penetrates the breathable layer 104. Due to the excellent ventilation and breathability of the three-dimensional mesh structure composed of one of the following: polyolefin elastomer, thermoplastic polyester elastomer, polyethylene elastomer, and polypropylene elastomer, the sweat that penetrates the breathable holes 103 does not stagnate on the surface of the breathable layer 104. Instead, it quickly diffuses outward through the material of the breathable layer 104 itself and is eventually discharged outside the backpack, thus preventing moisture from accumulating between the back and the backpack. When the backpack is under pressure, the breathable layer 104, made of one of the following: polyolefin elastomer, thermoplastic polyester elastomer, polyethylene elastomer, and polypropylene elastomer, absorbs and disperses the impact pressure of the backpack on the back due to its good elasticity and compression resilience, providing a comfortable cushioning effect. Even under pressure, the innermost breathable fabric 102 still maintains a small gap with the user's back, preventing the breathable holes 103 from being blocked due to complete contact, ensuring that the path for sweat to escape is always unobstructed.

[0027] Example 2:

[0028] Based on Embodiment 1, component 3 is disassembled. Component 3 is connected to the back ventilation structure 1. Component 3 includes a connecting strap 301, a zipper 302, and a zipper pull 303. The zipper 302 is horizontally positioned on the outer surface of the connecting strap 301, which is located on the upper middle side of the ventilation mesh 101. The zipper pull 303 is provided on the outer surface of the zipper 302 and is slidably positioned on the zipper teeth. The back ventilation structure 1 is shaped to fit the back of the backpack 2. The two ends of the connecting strap 301 are sewn together on the left and right sides of the back of the backpack 2, and the upper and lower sides of the connecting strap 301 separate the ventilation mesh 101. In addition to the zipper 302, it includes, but is not limited to, Velcro, buckles, and buttons. The backpack can be detached using various methods such as knots, magnetic snaps, and split embedding. When the backpack is in normal use, the zipper 302 on the outer surface of the connecting strap 301 is closed, and the internal breathable layer 104 and breathable fabric 102 are securely contained within. When the user needs to remove or replace the core functional layer, first operate the zipper pull 303 to slide it along the teeth of the zipper 302. Opening the zipper 302 opens the upper and lower sides of the breathable mesh 101. At this time, the user can easily remove the entire back breathable structure 1 composed of the breathable layer 104 and the breathable fabric 102 for subsequent cleaning, drying, or disinfection, completely solving the problem of traditional backpacks being difficult to clean and prone to bacterial growth.

[0029] The above description is merely a preferred embodiment of this application and is not intended to limit this application.
