Abstract

The invention discloses a backpack with a heat dissipation pad. A pad is arranged between the backpack and a human body contact face; the upper layer face of the pad is in contact with the backpack, and the lower layer face of the pad is in contact with a human body; the upper layer face and the lower layer face are netty and are connected with each other through some supporting rods; the density and the regular arrangement of the supporting rods do not greatly influence flowing of air; and therefore, heat produced by the back of the human body can be dissipated from the netty lower layer face and brought away by the air flowing between the two layer faces.

Description

The knapsack that cooling pad is arranged

Affiliated technical field

The invention belongs to the technical field of life appliance class.

Background technology

Knapsack is the instrument in the very familiar life of people, if we carefully investigate: almost on average everyone has a knapsack in the world, and somebody oneself people just has several knapsacks, and the problem of visible knapsack is not allowed not look.What problem does knapsack have on earth? historical so far all knapsack all is to haul the back of the body at back by several straps, not only reliable but also fashionable like this, does does having the people also to dare structure to knapsack present one's view or change? we are calm once to examine: the people produces very large heat when carrying the knapsack walking, the maximum that the heat of human body falls apart and from the back side, because the back is in the top large tracts of land part of human body, the situation that people usually use " sweat flows the chivalrous back of the body " to describe the human body adstante febre, but knapsack has but covered this a part of people's bulk area makes heat be difficult to distribute, like this people carry the bag walking can leicht fallen D/A weak, tired, although the problem that musette bag occurs is not obvious, but for large knapsack, particularly the knapsack in the army is very serious on the impact of the heat loss of human body, and each soldier's hyperthermia and fast appearance fatigue can weaken the fighting capacity of army.

Summary of the invention

Hinder the shortcoming of human motion heat radiation in order to change knapsack, I have invented a kind of special knapsack, this knapsack is the same with general knapsack, just between knapsack and people's contact level, installed a cooling pad additional the heat of human body can be scattered and disappeared away from people's back, like this people carry the knapsack walking time can feel to feel nice and cool, easily a lot.But installed the weight that such one deck cooling pad can increase the weight of knapsack additional, how to accomplish to make the little not only firm but also thermal diffusivity of this cooling pad weight is well the major issue that the present invention will solve as far as possible.

The technical scheme that technical solution problem of the present invention is taked is: install a pad between knapsack and people's contact level additional, the upper aspect of this piece pad contacts with knapsack, subsurface contacts with human body, upper and lower aspect is made into netted, there are some support bars to be connected between upper aspect and subsurface, the density of support bar and well-regulated arrangement can not cause on the circulation of air large impact, like this, human body can be dispersed into out again and can be taken away by the air that flows between two aspects from netted subsurface from the heat of back generation.

What is the material of cooling pad of the present invention? because the pressure that this layer pad will support is different, the large knapsack that has will support tens jin pressure, will use wire material so; The musette bag that has needn't support very large pressure, and light aluminium or plastics are just passable again to adopt the fine weight of some hardness; The special knapsack that has can be selected again large alloy material of better lightweight hardness such as the knapsack of army.

Cooling pad subsurface of the present invention is made into netted, and network structure can distribute the human heat, and network structure is even to the pressure at the back side of human body, and network structure also makes support bar install between two aspects equably and supports.A lot of knapsacks on the market all are comfortablely to install one deck foam-rubber cushion additional wrapping for the people is carried now, such structure is unscientific, foam-rubber cushion not only makes easier the accumulating of heat become heat keeper and also not change the sensation of feeling bad, because no matter you have added any pad, knapsack does not reduce people's pressure, increased the weight of on the contrary, certainly, the problem of dispelling the heat needn't be considered in the area of the cold that has.

The upper aspect of cooling pad of the present invention and the supporting way of the support bar between subsurface are that the perpendicular slice support bar adds and the angled brace supporting way of aspect, also can all use brace to support, because brace and aspect consist of a lot of triangles, triangle is the most firm shape.If support bar is at right angle setting all, all support bar is to predominate for so such cooling pad possibility pressurized, and this cooling pad has just collapsed.The too dense of support bar can affect the circulation of air and increase weight, and it is inadequate again to have dredged very much its support force, and this is really although this cooling pad simply but has a lot of technology to make us puzzling one's brains.Be what kind of knapsack what kind of cooling pad that weight by knapsack designs or designs by the compression capability of cooling pad so? that to have had knapsack to go to buy loose paying somebody's debt and expecting repayment later be that the cooling pad that family has removes to buy a knapsack that is fit to again to family again? or buy a knapsack of being furnished with cooling pad? these minor issues needn't have been answered one by one, and the appearance of any new things all can have a lot of problems to come the back will to solve.Having the correct theory of the knapsack of cooling pad to resemble one powerful revolutionary force saves up strength to start out.

The invention has the beneficial effects as follows: when the people carries the knapsack walking that cooling pad is arranged, pressing the knapsack position at people back can give out heat, nice and cool, light, happy, the indefatigability of sensation when the people walks like this.

Fig. 2 is the horizontal lateral plan of cooling pad knapsack of the present invention.

Fig. 3 is the wave knuckle supporting steel strand between cooling pad two aspects.

Among the figure, 1 aspect net, 2 straight line steel wire bars, the curved steel wire bar of 3 streamlines, 4 steel wires handing-over chalaza, 5 steel wire support bars, 6 wave knuckle steel wire bars, 7 knapsacks, 8 heat insulating mattress, 9 backpack strips.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is piece layer face steel wire of the present invention (1), and the steel wire of upper and lower two aspects of cooling pad of the present invention is the same.Steel wire among Fig. 1 sees not to be cuboid or the square of rule on the whole, but the shape attitude of the slightly wide streamline periphery of top narrow lower portion, the shape that the people of the suitable general knapsack of such shape carries on the back contact-making surface, certainly, also the knapsack of regular shape needs the cooling pad of regular shape.It is netted to see among Fig. 1 that the mutual vertical plane of straight line steel wire bar (2) is woven into, and interface point (4) can be pad or weaving point.There is fusiform bent steel strand (3) top and the bottom of also seeing the aspect net among Fig. 1, and this is to be avoided the horn shape body in the appearance of cooling pad side perimeters, have not only reduced the weight of unnecessary horn shape body but also avoided the possibility injury of horn shape body to human body.

We have seen the horizontal side view of cooling pad knapsack among Fig. 2.The knapsack of this figure is the same with general knapsack (comprising multiple knapsack), just the people's contact level at knapsack has installed a cooling pad (8) additional, the size of this piece cooling pad should be the same with the size of people's contact level of knapsack (7), but cooling pad can not be too less than knapsack, and blocks air flows to cooling pad because knapsack might the edge hangs down affects heat sinking function.See among Fig. 2 and have a lot of steel wire support bars (5) that two aspects are maintained a certain distance between upper and lower two aspects (1).The distance of upper and lower two aspects is fixed, and has connected and composed a lot of triangle bodies because two the adjacent support bars between two aspects are relatively oblique, and the triangle body pressurizes and also do not change shape.Between relative two straight line steel wire bars (2) support bar (5) is arranged on upper and lower two aspects, the triangle body that these support bars consist of also is the same rule, and this enters into air seldom to hinder between two aspects and can take heat out of fast.The operation principle of cooling pad is: the heat that gives out from the human body back side is directly to enter between two aspects or be transmitted in the steel wire bar all can be taken out of cooling pad by the air between two aspects of inflow, blowing of people's walking or wind is the power of circulation of air, so cooling pad of the present invention does not need the energy that operation power is provided.See among Fig. 2 that this cooling pad shape resembles straight plate, although there is the triangle that is much consisted of by the steel wire bar to fix on the cooling pad, but thisly be fixed with certain limit, just locality is fixing, area is large can integral body can slightly make the curved shape of elasticity, and this is so that cooling pad can slightly be made at people's the back side back side feature that the curved lid shape of elasticity just is fit to the people.

Fig. 3 is the shape of a wave knuckle steel wire bar (6).The purpose of this figure is to illustrate that the support bar (5) in the cooling pad can be the edge strip part that is angled from the consecutive identical angle of rule with a rectangular steel wire bar.Like this, all material reality of cooling pad of the present invention all is rectangular steel wire bar: upper and lower aspect (1) is rectangular steel wire bar reticulate body; Be rectangular steel wire bar wave fold angle type support bar (5) between aspect, the interface point (6) of all steel wire bars all is pad, and the form of welding can at will not fall apart cooling pad to take off.

The selected material of cooling pad of the present invention is the steel wire bar, whether is other material not suitable for? be not like this, other alloy material also may have than the better characteristics of steel wire bar; We first the material of usefulness should be hardness, the density of material, the combination of price, hardness is good, the steel wire bar support force that density is large is large, the heat conduction is fast, its Jie's lattice are not high yet, but if the knapsack of some special forces, and they consider but is function and do not minded its price, the material of their knapsack cooling pad may select some hardness large, lightweight alloy material.Also has an important ideological problem: be the necessity of having considered its installation because cooling pad has increased the weight of knapsack? answer is: any instrument is certain weight all, on the mankind's history, the human decision of never abandoning using this instrument because of the weight of some instrument, for example: people can not abandon wearing footwear because of the weight of footwear, although that the people does not wear footwear is passable yet; People can not abandon wearing cotton dress because of the weight of cotton dress, although it is also passable not wear cotton dress.

There is the invention of the knapsack of cooling pad to resemble one powerful correct revolutionary force and will impacts the now family of the whole world tens knapsacks, soon, only have summer the fool just to carry in the street and do not had the knapsack of cooling pad.
