Detailed Description

So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

Some embodiments according to the invention are described below with reference to the drawings.

As shown in fig. 1, 2 and 7, the present invention provides a backpack having a heat dissipation function, comprising: first wind channel structure 1, first wind channel structure 1 includes: the first sealing layer 11, the first sealing layer 11 has air outlet groups; the second sealing layer 12, the second sealing layer 12 and the first sealing layer 11 form a first air duct, and the first air duct is provided with a first air inlet; the air outlet device 4 is provided with a second air inlet and an air outlet; the elastic supporting piece is arranged in the first air channel; an air outlet of the air outlet device 4 is communicated with a first air inlet of the first air duct structure 1.

The elastic supporting piece is arranged in the first air duct structure 1 to form support, so that on one hand, deformation caused by extrusion of a human body on the first air duct can be reduced, the volume of the first air duct is favorably maintained, and meanwhile, the impact of the first air duct on the human body during carrying is reduced; the air outlet device 4 is used for changing the air flow speed in the first air channel structure 1, and the air flow passes through the position where the human body is in contact with the first air channel so as to keep the position dry and cool.

The first air duct may have a linear shape, a curved shape, or other regular or irregular shapes.

As shown in fig. 2, the first sealing layer 11 and the second sealing layer 12 may be made of a gas-impermeable material, such as rubber, chemical fiber, dacron, and the like. The first sealing layer 11 and the second sealing layer 12 made of airtight materials are beneficial to adjusting the flow direction of the first air channel, so that air flow enters from the air inlet and flows out from the air outlet group.

The arrangement of the air outlet hole group and the arrangement of the air inlet are beneficial to the air flow to pass through a first air channel formed by the first sealing layer 11 and the second sealing layer 12, so that the circulation speed of the contact position of a human body and the first air channel is increased, and the contact position is kept dry. The contact position of the first air duct and the human body is generally the first sealing layer 11, and because the human body is not always in pressure contact with the first sealing layer 11, gaps are generated at the contact position, air flow can leave the first air duct through the air outlet group, and the air flow circulation speed at the contact position is increased, so that the effect of keeping the contact position dry and cool is achieved. The number of rows of the air outlet group may be 1 row, and may be multiple rows, and the number of holes of the air outlet group may be 1, and may be multiple rows, and the number of holes of the air outlet group is not limited herein.

The air output of the air outlet can be adjusted by setting the aperture of the first air outlet group 111. As shown in fig. 3 and 4, the first air inlet is disposed at one end of the first air duct; the air outlet group comprises a first air outlet group 111, and holes in the first air outlet group 111 are arranged along the extending direction of the first air duct; the aperture of the holes in the first air outlet group 111 close to the first air inlet is smaller than the aperture of the holes in the first air outlet group 111 far away from the first air inlet. When the air current gets into first air intake, the velocity of flow is fast, and after getting into first air intake, the velocity of flow of air current diminishes gradually, so the aperture that sets up the hole in the first air outlet group 111 that is close to first air intake is little, and the aperture of the hole in the first air outlet group 111 that keeps away from first air intake is big to keep the airflow flow who flows from each first exhaust vent unanimous relatively. Maintaining a relatively uniform airflow rate may allow uniform heat dissipation from the holes in the first air outlet group 111 around the first air duct, which may avoid overheating and wetting of the contact position.

The first outlet group 111 cannot take over the flow of the excessive air. When the air flow of the air inlet reaches a certain degree, the air flow is often caused to form turbulent flow in the first air channel. The presence of turbulence reduces the velocity of the airflow and slows the airflow at the point of contact. The second air outlet group 112 is arranged, and the holes in the second air outlet group 112 are arranged along the extending direction of the first air duct, so that the condition of turbulent flow caused by overlarge airflow can be avoided.

Optionally, the number of the first air outlet group 111 is set to 1 group, and the number of the second air outlet group 112 is set to 2 groups, so as to avoid the occurrence of turbulent flow.

As shown in fig. 4, the holes of first outlet group 111 may be staggered with the holes of adjacent second outlet group 112. The air outlet groups are in multiple rows, and the holes of the air outlet groups in two adjacent rows are arranged in a staggered mode.

The aperture of the holes in the second outlet group 112 close to the air inlet may also be smaller than the aperture of the holes in the second outlet group 112 far from the air inlet.

The elastic supporting piece is arranged in the first air channel and can maintain the volume of the first air channel. When the human body contacts with the first air channel, the first air channel is often extruded, the airflow in the first air channel is reduced after the first air channel is extruded, and the contact position is not kept dry. When the human body extrudees first wind channel, elastic support piece can reduce the extruded degree of first wind channel through taking place deformation to maintain the volume in first wind channel, be favorable to avoiding the moist phenomenon of contact position to appear. The elastic support may include: a first stopper layer 131, an elastic element 133 and a second stopper layer 123, the elastic element 133 being disposed between the first stopper layer 131 and the second stopper layer 123. The first limiting layer 131 and the second limiting layer 123 are arranged to limit the elastic element 133, and maintain the posture of the elastic element 133 after being installed in the first air duct, so as to achieve the supporting effect. For example, the first stopper layer 131 and the second stopper layer 123 may be planes woven by cotton threads, and the elastic element 133 may be a plastic thread having elasticity, which is repeatedly passed through the two planes to dispose the elastic element 133 between the first stopper layer 131 and the second stopper layer 123, thereby making the elastic support. The elastic element 133 may also be a spring, or any other object with elasticity. These can all be regarded as the elastic element 133 of this application, set up between first stopper layer 131 and second stopper layer 123, realize the support effect to first wind channel.

It will be appreciated that the cushioning material will often have good air permeability and that the air leaving through the vents can exit directly through the air permeable layer 15 to increase the speed of air flow across the surface of the body.

The material of the air-permeable layer 15 can be a mesh structure such as sponge, and the arrangement of the air-permeable layer 15 enables the air flow in the first air channel to leave the first air channel through the air outlet group, so that the air flow speed of the contact position of the human body and the first air channel is increased, and the contact position is kept dry and cool.
