[0020] refer to Figure 1 and Figure 2 The utility model provides an engine packaging box with a hidden gas charging and discharging port, comprising: a box cover 1 and a base 2.

[0021] The bottom surface of the box cover 1 is open, and the interior is hollow. The edge of the opening is sealed and connected to the base 2. The hollow interior is used to accommodate the engine and its mounting bracket and accessories.

[0022] The box cover 1 may have various shapes, such as a square box shape, a cylindrical shape, a hemispherical shape, etc. This embodiment takes a direction box as an example.

[0023] The side wall of the box cover 1 is provided with a document placement area 3 and an instrument installation area 4 which are recessed inwards. The document placement area 3 is used to store engine-related documents and product history, and the instrument installation area 4 is used to arrange an inflation valve 7, an air release valve 8, a safety valve 9, a pressure gauge 10 and a humidity indicator 11.

[0024] The opening of the document placement area 3 is movably connected with a first cover plate 5, and the opening of the instrument installation area 4 is movably connected with a second cover plate 6. As an example, the first cover plate 5 is rotatably connected to the outer wall of the document placement area 3 by a hinge, and the second cover plate 6 is rotatably connected to the outer wall of the instrument installation area 4 by a hinge. The first cover plate 5 can block the interior of the document placement area 3, and the second cover plate 6 can block the interior of the instrument installation area 4 and protect the instruments and valves therein to avoid being exposed to the outside.

[0025] The inside of the instrument installation area 4 is provided with embedded parts, and the two sides of the embedded parts are respectively the inside of the box cover 1 and the inside of the instrument installation area 4; the inflation valve 7, the deflation valve 8, the safety valve 9, the pressure gauge 10 and the humidity indicator 11 are installed on the embedded parts, and the inflation valve 7, the deflation valve 8, the inner end of the safety valve 9 and the pressure gauge 10 and the humidity indicator 11 probe are located in the internal space of the box cover 1. When the pressure gauge 10 detects that the air pressure inside the packaging box is too high, the deflation valve 8 is used to exhaust, and when the pressure is too low, the inflation valve 7 is used to inflate. The safety valve 9 is used as an additional insurance measure. When the humidity indicator 11 detects that the humidity inside the box is too high, dry gas is filled to ensure that the humidity inside the box is appropriate. The inflation valve 7, the deflation valve 8, the safety valve 9, the pressure gauge 10 and the humidity indicator 11 are common components and can be selected according to needs.
