Description

Technical Field

[0001] This utility model discloses a backpack technology, and in particular relates to a breathable backpack. Background Technology

[0002] Backpacks are a general term for bags carried on the back when going out. With the increase in carrying time and the amount of items inside the backpack, the wearer will feel tired and sweat. As a result, a lot of sweat will be generated on the back of the backpack. After a long period of use, the backpack will be soaked and unable to wick away the sweat in time, which can easily cause itchy and uncomfortable skin for the wearer. Therefore, a new backpack product is needed. Utility Model Content

[0003] The purpose of this invention is to provide a breathable backpack to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a breathable backpack, comprising a bag body and a breathable component disposed on the back panel of the bag body. The breathable component includes two upper back sections, two middle back sections, two side back sections, and two lower back sections, which are symmetrically arranged according to the back muscle groups. A flow channel is provided between the eight sections of the breathable component, and several mesh holes are provided in the eight sections of the breathable component near the carrying area.

[0005] Preferably, the weaving structure of the eight regions of the breathable component includes a mesh layer, an inner layer, and an intermediate layer. The mesh is disposed on the mesh layer, and both the inner layer and the intermediate layer adopt a mesh structure. The weaving density of the mesh structure in the intermediate layer is greater than that in the inner layer.

[0006] Preferably, the intermediate layer is made of hydrophobic yarn and the inner layer is made of hydrophilic yarn.

[0007] Preferably, the eight regions of the breathable component have flow channels that are interconnected in the middle region of the breathable component.

[0008] Preferably, the mesh on the mesh layer is arranged in a ring array and is concave towards the side of the package in an arc shape.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This product utilizes a multi-layer structure in its breathable components, with the middle layer having a higher fiber density than the inner layer, creating an additional pressure difference. When sweat is absorbed and penetrates into the middle layer through the mesh of the mesh layer, it is driven to diffuse into the inner layer under the additional pressure difference. The middle and inner layers form a hydrophilic / hydrophobic gradient, enabling unidirectional sweat transmission. The mesh on the mesh layer is arranged in a ring array and is concave towards the side of the bag in an arc shape, which can reduce the stickiness to the skin and improve comfort when carrying the bag.

[0011] The eight drainage channels of the breathable component are interconnected in the middle area of ​​the breathable component. This area on the back has a high concentration of sweat glands and is the area with the most sweat. The drainage channels allow sweat to spread quickly to various areas, reducing sweat accumulation in this area, increasing the evaporation area of ​​sweat on the back, accelerating sweat evaporation, and keeping the breathable component dry overall.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] A breathable backpack, such as Figure 1 As shown, it includes a bag body 1 and a breathable component 2 disposed on the back panel of the bag body 1. The breathable component 2 includes two upper back 3, two middle back 4, two side back 5 and two lower back 6, which are divided into eight regions symmetrically arranged according to the back muscle groups. A guide channel 7 is provided between the eight regions of the breathable component 2, and several mesh holes 8 are provided near the carrying area of ​​the eight regions of the breathable component 2.

[0019] like Figure 2 and Figure 3 As shown, the weaving structure of the eight areas of the breathable component 2 includes a mesh layer, an inner layer, and a middle layer. The mesh layer is the top layer and closest to the user's back. The middle layer is located between the mesh layer and the inner layer. Mesh 8 is set on the mesh layer. Both the inner and middle layers use a mesh structure. The weaving density of the mesh structure in the middle layer is greater than that in the inner layer. This multi-layer structure, with the middle layer having a higher fiber density than the inner layer, creates an additional pressure difference. When sweat is absorbed and permeates through the mesh 8 of the mesh layer into the middle layer, it is driven to diffuse towards the inner layer under the additional pressure difference. Furthermore, the middle layer uses hydrophobic yarn, while the inner layer uses hydrophilic yarn, forming a hydrophilic / hydrophobic gradient. Combined with the hydrophilic design of the inner layer, this achieves unidirectional sweat transmission. Figure 4 As shown, the mesh 8 on the mesh layer is arranged in a ring array and is concave towards the side of the package 1 in an arc shape, which can reduce the stickiness to the skin and improve comfort.

[0020] The eight drainage channels 7 of the breathable component 2 are interconnected in the middle area of ​​the breathable component 2. The back area has a relatively dense concentration of sweat glands and is the area with a large amount of sweat. The drainage channels 7 allow sweat to spread quickly to each area, reducing sweat accumulation in this area, increasing the evaporation area of ​​sweat in the back area, accelerating sweat evaporation, and keeping the breathable component 2 dry overall.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
