Abstract
The utility model discloses an EVA compress-moulded breathable structure of backpack back. The breathable structure forms a backpack back and is characterized in that the breathable structure is an EVA layer and comprises a first group of projections disposed at upper and lower ends and in the middle, a second group of projections corresponding to shoulder blades of a human body, and at least one pair of third projections corresponding to the back and waist of the human body. A gap forms each two adjacent projections of the breathable structure, so that a gap is also reserved between contact parts of the backpack back and the human back; hot gas produced by the human back is easily guided out from the gaps during the use of a backpack, and accordingly natural ventilation and drying is achieved. In addition, sweat produced by the parts of the projections of the breathable structure, in contact with the human back, can be absorbed by the EVA material, and a wearer is prevented from catching a cold due to the accumulated sweat. The breathable structure is formed by single compression moulding, so that production efficiency is improved.
Description
Technical field
The utility model relates to ventilating structure, particularly the ventilating structure of knapsack back of the body width EVA moulded section.
Background technology
At present common knapsack is all generally to adopt fibers material to make on the market, although that fibers material has is convenient clear
The functions such as clean, waterproof, but air permeable effect is poor, the knapsack back side is without heat sinking function, in use knapsack back of the body width with human body near contacting, especially during the broiling summer, knapsack back of the body width and the human body back contact site clothes that is more easily wet with sweat, knapsack back of the body width and human body back tight, causing cannot natural draft drying, easily causes user's skin discomfort, sufferings and inflammation, and the sweat storing after cooling easily causes user to catch a cold.
EVA (ethylene-vinyl acetate copolymer) material has the advantages such as good buffering, antidetonation, heat insulation, moistureproof absorbing sweat, and at present, China's EVA material is mainly used in foaming in shoe material.
Summary of the invention
The purpose of this utility model is to provide a kind of moistureproof absorbing sweat, the ventilating structure of the EVA moulded section for knapsack back of the body width of good heat dissipation effect.
For achieving the above object, the utility model is by the following technical solutions: the ventilating structure of knapsack back of the body width EVA moulded section, described ventilating structure forms inclusion back of the body width, described ventilating structure is EVA material layer, first group of projection that in the middle of this ventilating structure comprises, upper/lower terminal arranges, second group of projection of setting corresponding to human body both sides shoulder blade, more than one pair of the 3rd group of projection of setting corresponding to human body back and waist.
Adopt above structure, the ventilating structure of knapsack back of the body width is by EVA moulded section, has the advantages such as good buffering, antidetonation, heat insulation, moistureproof absorbing sweat due to EVA material, thereby makes knapsack back of the body width have the advantages such as ventilative, heat radiation.Simultaneously, the ventilating structure of knapsack back of the body width is provided with three groups of projections, forms gap between adjacent projections, and knapsack back of the body width and human body back contact site exist gap like this, people use the hot gas Yi Cong gap that in knapsack process, back produces to lead away, reach the effect of natural draft drying.In addition, the sweat that the projection on knapsack back of the body width ventilating structure and human body back contact site produce can be adsorbed by EVA material, stores sweat and cause user to catch a cold after avoiding lowering the temperature.
Three groups of projections that arrange on the ventilating structure of knapsack back of the body width match with human body back, thereby it is more comfortable that knapsack is used.
Described ventilating structure is by pressing mold one-shot forming, and processing technology is simple.
The 3rd group of projection of described ventilating structure is two pairs.
The ventilating structure of the utility model knapsack back of the body width EVA moulded section, this ventilating structure is provided with three groups of projections, between adjacent projections, form gap, there is gap in knapsack back of the body width and human body back contact site like this, people use the hot gas Yi Cong gap that in knapsack process, back produces to lead away, reach the effect of natural draft drying.In addition, the sweat that the projection on knapsack back of the body width ventilating structure and human body back contact site produce can be adsorbed by EVA material, stores sweat and cause user to catch a cold after avoiding lowering the temperature.Ventilating structure, by pressing mold one-shot forming, has been simplified one-tenth production. art, has improved production efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the ventilating structure of the utility model knapsack back of the body width EVA moulded section.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in further detail:
As shown in Figure 1, the ventilating structure 4 of the utility model knapsack back of the body width EVA moulded section, described ventilating structure 4 forms inclusion back of the body width, described ventilating structure is EVA material layer, first group of projection 1 that in the middle of this ventilating structure comprises, upper/lower terminal arranges, second group of projection 2 of setting corresponding to human body both sides shoulder blade, more than one pair of the 3rd group of projection 3 of setting corresponding to human body back and waist.
Described ventilating structure 4 is moulded section.
The 3rd group of projection 3 of described ventilating structure 4 is two pairs.
When the ventilating structure of the utility model knapsack back of the body width EVA moulded section is used, because ventilating structure is provided with projection, between user back and knapsack, form gap, even if heat also can be dried after perspiring in time like this, can not affect the healthy of user.Knapsack back of the body web material is ventilative good EVA material, and the hot gas between user back and knapsack also can be good at leaving like this, and EVA material light weight, when having good air permeable effect, can not bring burden to user.
