Abstract
The utility model discloses EVA material back of the body width stereo shaping ventilating structure knapsack, it comprises knapsack body, the back side of described knapsack body is provided with the cushion of arc convex, described cushion is shaping by EVA material, and being located at the middle part at the knapsack body back side, the surface of described cushion is provided with air guide structure.The utility model just arranges the cushion with air guide structure at the middle part at the knapsack back side, when cushion is resisted against human body back, larger gap is all formed above and below cushion and between human body, effectively can carry out cross-ventilation with the air guide structure on the surface of cushion, thus effectively the heat that human body back produces be taken away.In addition, the shaping cushion of EVA material has the advantages such as high resiliency, high flexibility, highly-breathable, and the use sense that can improve use is further subject to.The utility model structure is simple, not only material cost is greatly reduced, and has significant ventilating permeability effect.
Description
Technical field
The utility model relates to EVA material back of the body width stereo shaping ventilating structure knapsack.
Background technology
The back side of existing common knapsack does not generally arrange special ventilating structure, when heat, user is when bearing knapsack, due to very close to each other between knapsack and the back of user, the function of absorbing sweat and the backing material making knapsack is also breathed freely, therefore the back of user cannot aeration-drying, and result of use is not good enough.In addition, occurred that the back side of some knapsacks has ventilating structure on the market, this back of the body width structure occupies the whole back side of knapsack, has certain ventilating permeability effect, but result of use or not good enough, and waste material.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is to provide simple, with ventilated function the EVA material of a kind of structure to carry on the back width stereo shaping ventilating structure knapsack.
For achieving the above object, the utility model is by the following technical solutions:
EVA material back of the body width stereo shaping ventilating structure knapsack, comprise knapsack body, the back side of described knapsack body is provided with the cushion of arc convex, and described cushion is shaping by EVA material, and being located at the middle part at the knapsack body back side, the surface of described cushion is provided with air guide structure.
Described air guide structure comprises the leading chute running through cushion upper/lower terminal, and the upper/lower terminal of described leading chute forms two points of prongs respectively; Described cushion is equipped with the guiding gutter be communicated with leading chute in the surrounding of leading chute.
The bottom surface of described guiding gutter is provided with air-vent.Air-vent can improve ventilated effect further.
The utility model adopts above technical scheme, just the cushion with air guide structure is set at the middle part at the knapsack back side, when cushion is resisted against human body back, larger gap is all formed above and below cushion and between human body, effectively can carry out cross-ventilation with the air guide structure on the surface of cushion, thus effectively the heat that human body back produces be taken away.In addition, the shaping cushion of EVA material has the advantages such as high resiliency, high flexibility, highly-breathable, and the use sense that can improve use is further subject to.The utility model structure is simple, not only material cost is greatly reduced, and has significant ventilating permeability effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details:
Fig. 1 is the front view of the utility model EVA material back of the body width stereo shaping ventilating structure knapsack;
Fig. 2 is the side view of the utility model EVA material back of the body width stereo shaping ventilating structure knapsack.
Detailed description of the invention
As shown in Figure 1 or 2, the utility model comprises knapsack body 3, and the back side of described knapsack body 3 is provided with the cushion 1 of arc convex, and described cushion 1 is shaping by EVA material, and being located at the middle part at knapsack body 3 back side, the surface of described cushion 1 is provided with air guide structure 2.
Described air guide structure 2 comprises the leading chute 21 running through cushion 1 upper/lower terminal, and the upper/lower terminal of described leading chute 21 forms two points of prongs respectively; Described cushion 1 is equipped with the guiding gutter 22 be communicated with leading chute 21 in the surrounding of leading chute 21.
The bottom surface of described guiding gutter is provided with air-vent 23.Air-vent 23 can improve ventilated effect further.
The utility model just arranges the cushion 1 with air guide structure 2 at the middle part at the knapsack back side, when cushion 1 is resisted against human body back, larger gap is all formed above and below cushion 1 and between human body, effectively can carry out cross-ventilation with the air guide structure 2 on the surface of cushion 1, thus effectively the heat that human body back produces be taken away.In addition, the shaping cushion 1 of EVA material has the advantages such as high resiliency, high flexibility, highly-breathable, and the use sense that can improve use is further subject to.The utility model structure is simple, not only material cost is greatly reduced, and has significant ventilating permeability effect.
