Description:
TECHNICAL FIELD 
     The present invention relates to the technical field of cold insulation equipment for cold chain transportation, and particularly to an inflatable insulation box. 
     BACKGROUND ART 
     In the industries of outdoor sports and logistics, there is usually a requirement to store and transport temperature-sensitive products or articles, such as pharmaceutical vaccine articles, fresh foods, fruits, cold drinks, foodstuff and the like, which should be maintained within an appropriate temperature range during transportation so as to ensure the quality of the transported articles. It needs more than ever to keep temperature and freshness of products as the rise of food E-commerce. 
     Now, EPP (Expanded polyproplene) boxes are commonly applied to current insulation boxes, i.e. insulation boxes made from polypropene plastic foam materials. However, the EPP boxes have disadvantages as shown below:
         1. It takes much efforts to separate a lid from the EPP box as it is not easy to open the lid;   2. Cold insulation performance is poor, and space utilization is inefficient due to a heavy ice plate which occupies a relatively large space in the box, generally, under the requirements of cold insulation, an 8 kg-ice plate is required to be placed onto a 25 L incubator to meet the needs;   3. The body of the EPP box is relatively thick and cannot be folded, occupying too much space.       

     In the current market, there are also insulation boxes with a box body filled with a foam layer, which can be compressed and folded if empty to decrease the space occupied. However, such box body has barely satisfactory thermal insulation performance, and has no obvious effects on space saving.

     Further, the box body includes a front side face, a rear side face, a left side face, a right side face and a bottom face which are integrally connected, and the box lid is integrally connected with the rear side face of the box body; and creases are provided between the individual faces of the box body and between the box lid and the box body. 
       FIG. 1  is a front schematic view of an inflatable insulation box provided by an example of the present invention when closed;  FIG. 2  is a side schematic view of the inflatable insulation box shown in  FIG. 1  when closed;  FIG. 3  is a front schematic view of the inflatable insulation box shown in  FIG. 1  when a box lid is opened;  FIG. 4  is a side schematic view of the inflatable insulation box shown in  FIG. 1  when a box lid is opened;  FIG. 5  is a top view of the inflatable insulation box shown in  FIG. 1  when a box lid is opened; and  FIG. 6  is a structural schematic view of the inflatable insulation box shown in  FIG. 1  when completely unfolded. 
     As depicted in  FIG. 1-6 , the inflatable insulation box provided by the example comprises a box body  1  and a box lid  2 . 
     The box body  1  is integrally connected with the box lid  2 . Specifically, the box body  1  comprises a front side face  101  of the box body, a bottom face of the box body, a left side face  103  of the box body, a right side face  104  of the box body and a rear side face  105  of the box body that are integrally connected, and the box lid  2  is integrally connected with the rear side face  105  of the box body. This generates the unfolded view as depicted in  FIG. 6 . The inflatable insulation box described in the example can be obtained by folding the individual faces of the box body and the box lid, in which the box body  1  has an opening and the box lid  2  is configured to close the opening of the box body  1 . 
     The individual faces of the box body  1  and the box lid  2  comprise fabrics on the outer layers and airbags  6  on the inner layers, respectively, and the airbags on the individual faces of the box body  1  communicate with the airbags of the box lid  2  to form an integer. An air valve  3  is provided on the front side face  101  of the box body  1  and configured to inflate or deflate all of the airbags  6  of the box body  1  and the box lid  2 . 
     In other solutions of the example, the airbags of the individual faces of the box body  1  may not communicate or selectively-partially communicate with the airbags of the box lid  2 , and the air valve  3  is provided on the box body  1  or the box lid  2  and configured to communicate with the airbags of the individual parts. 
     Airbags used for thermal insulation result in a better performance. When stored, the air valve can be opened, and the box body and the box lid are squeezed to deflate the airbags, and folded up after compressed so as to minimize the volume for storage. 
     The inner surfaces on the outer layers of the box body  1  and the box lid  2  are configured as reflective fabrics so as to allow the inflatable insulation box to have a better thermal insulation effect. For example, the common fabrics may have surfaces coated with metallic silver to make them become reflective fabrics. 
     The utilization of reflective fabrics can well improve the thermal insulation performance of the box body. 
     The outer fabrics of the box body  1  and the box lid  2  may be PVC sandwich weaved materials, i.e. polyvinyl chloride materials. On the one hand, as the outer fabric, PVC sandwich weaved materials reduces the weight of the product due to their lighter weight, which facilitates product transportation, on the other hand, PVC sandwich weaved materials facilitate folding of the product, and allow the product to be easily cleaned. 
     In a preferable technical solution of the example, airbags on the individual faces of the box body  1  and the box lid  2  are all bar-like airbags closely arranged in parallel. The airbags on the individual faces of the box body  1  and the box lid  2  have a thickness not greater than 15 mm after being inflated. 
     The airbags employ mini bar-like airbags which are independent but communicate may effectively decrease the thickness after the airbags are inflated, providing a larger space inside the box body, and meanwhile effectively preventing airbag damages. 
     In the example, the opening of the box body  1  is connected with the box lid  2  by means of a waterproof zipper  4 . At the same time, with the purpose of achieving better thermal insulation performance, a sealing and thermal insulating strip is circumferentially disposed along inner edges of the box lid  2 , and capable of covering over the waterproof zipper  4 . 
     Connecting the box lid with the box body by means of the waterproof zipper facilitates the opening and closing of the insulation box and results in a good sealing effect and ease of use at the same time. The configuration of the sealing and thermal insulating strip ensures the sealing and thermal insulation effects at the waterproof zipper, improves the thermal insulation performance of the product and further insures that the product is capable of maintaining its internal temperature for a long time. 
     In the examples, a strap  5  is provided on the left side face  103  and the left side face  104  of the box body  1 . 
     In other solutions of the example, handles may be provided on the left side face  103  and the right side face  104  of the box body  1  respectively. The handles may be made of webbing and have an n-shaped structure. 
     In an preferable solution of the example, outer wall surfaces or inner wall surfaces of the box body  1  are provided with mesh bags. The mesh bags on the outer wall surfaces may be used for storing goods at room temperature, and the mesh bags on the inner wall surfaces may be configured to fix the articles inside the box body or store ice bags. 
     In an preferable solution of the example, creases  7  are provided among the front side face  101  of the box body, the bottom face  102  of the box body, the left side face  103  of the box body, the right side face  104  of the box body, the rear side face of the box body and the box lid respectively, so as to enable more convenient folding and compressing. 
     Finally, it should be indicated that, all of the above-mentioned examples are only used for illustration of the technical solutions of the present invention, and not for limiting it. Although the present invention have been detailed with reference to the foregoing examples, those skilled in the art shall understand that they can still make modifications to the technical solutions as illustrated by the foregoing examples or equivalent substitutions to a part or all of the technical features. Such modifications or substitutions shall not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions as illustrated by the examples of the present invention.
