The improved backpack is further improved in that the backpack is of a wedge-shaped structure and comprises a base cloth surface, a back cloth surface and two side cloth surfaces, the upper ends of one side of the base cloth surface and the upper end of the back cloth surface are fixedly connected with the back surface of the folding chair cloth, and the two side cloth surfaces are positioned on two side vertical surfaces of the backpack.

Still further, the width of the inner cavity of the backpack is gradually narrowed from bottom to top.

And furthermore, two air inlets are formed in the base fabric surface, a fan is detachably mounted above the air inlets, and an air outlet of the fan faces upwards.

Furthermore, one side of the bottom cloth surface, which is far away from the chair back, and the lower end of the back cloth surface are fixedly connected with a hook surface and a loop surface respectively, so that the bottom cloth surface is movably connected with the back cloth surface through the loop surface. The bottom cloth cover and the back cloth cover are movably connected so as to facilitate the installation and the disassembly of the fan arranged on the bottom cloth cover.

Still further, the air inlet is embedded with a first mesh.

Further improve, the air outlet department inlays and has the second screen cloth.

The utility model also provides a folding chair, be equipped with foretell folding chair heat radiation structure on folding chair's the back of the chair.

Through the utility model provides a technical scheme has following beneficial effect:

through set up flexible knapsack on the folding chair back of the chair, the knapsack inner chamber forms the wind channel, makes the air flow in from the knapsack below, flows out from the chair cloth to play the radiating effect of cooling, be favorable to improving user's use comfort. The backpack has certain leakproofness and flexibility, can be folded along with the folding chair while ensuring the air flow, and does not influence the storage of the folding chair.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "side", "center", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected: either mechanically or electrically: they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Fig. 1 to 6 show that a folding chair heat radiation structure is arranged on the back of a folding chair 10, and comprises a backpack 20 fixedly connected to the back of a folding chair cloth 11, wherein an air inlet 201 is arranged at the bottom of the backpack 20, a fan 30 is arranged at the air inlet 201, and an air outlet 111 communicated with the inner cavity of the backpack 20 is arranged on the folding chair cloth 11.

Specifically, as shown in fig. 3 and 4, the backpack 20 is of a wedge-shaped structure, and includes a bottom cloth 21, a back cloth 22, and two side cloth 23, wherein one side of the bottom cloth 21 and the upper end of the back cloth 22 are both fixedly connected to the back surface of the folding chair cloth 11, and the two side cloth 23 are located on two side vertical surfaces of the backpack 20. The bottom cloth cover 21, the back cloth cover 22 and the two side cloth covers 23 form a closed space as an air duct for air flow. The width of the inner cavity of the backpack 20 is gradually narrowed from bottom to top.

Be equipped with two air intakes 201 on the floorcloth cover 21, air intake 201 top demountable installation has fan 30, and fan 30's air outlet 111 is up, makes the wind that blows out flow from air outlet 111 through knapsack 20 inner chamber, cools down the heat dissipation to user's back. The direction of the arrows in fig. 4 indicates the direction of flow of the air. Of course, the number of the outlet 111 and the fan 30 is not limited thereto.
