Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a mildew-proof food packaging box. Background Art

[0002] As the name suggests, packaging boxes are boxes used to package products. They can be classified by material, such as paper boxes, iron boxes, wooden boxes, leather boxes, etc. They can also be classified by the name of the packaged products, such as moon cake boxes, tea boxes, food packaging boxes, etc.

[0003] A mildew-proof and breathable packaging box with publication number CN220501553U specifically includes a packaging box main body, a cavity is left in the packaging box main body, and a heating block is fixedly connected to the lower surface of the packaging box main body. The mildew-proof and breathable packaging box can effectively remove the internal moisture accumulation in the packaging box through the provision of a breathable film, a heating plate, etc., thereby greatly protecting the dry environment inside the packaging box. The breathable film and the heating plate can well exchange the gas inside the packaging box with the external gas, thereby effectively solving the problem that the freshness and shelf life of food and other perishable products are greatly reduced due to the poor ventilation effect of the commonly used packaging boxes. Even due to the internal moisture accumulation in the packaging box, especially for products that are easily affected by moisture or need to maintain a dry environment, there is no good dehumidification and mildew prevention means, which causes the product to be affected by moisture, deteriorate, or even moldy. In addition, the existing packaging boxes also have the following disadvantages during use:

[0004] (1) Although existing packaging boxes can achieve ventilation through breathable films, the material and pore size of the breathable films may affect the ventilation performance, thereby affecting the mildew-proof effect;

[0005] (2) There is only one heating plate inside the existing packaging box heating block, which may cause uneven temperature distribution inside the packaging box body and affect the anti-mildew effect. Utility Model Content

[0006] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a mildew-proof box for food packaging.

[0007] In order to solve the above problems, the technical solution of the present utility model includes:

[0009] A ventilation structure, the ventilation structure being arranged on a side of the ventilation hole away from the air vent;

[0010] A top cover is provided on the top of the packaging box body, and a plurality of fixing structures are provided between the top cover and the packaging box body;

[0011] There are several window ribs, and the several window ribs are equidistantly arranged inside the air vents. One end of the several window ribs is tilted upward, and the other end is tilted downward.

[0012] Furthermore, the ventilation structure includes a filter, a fixing frame, a fixed shaft, a fan and a shell. The shell is provided on the side of the ventilation hole away from the air vent. A filter is provided on one side of the interior of the shell, and a fixing frame is provided on the other side. A fixed shaft is provided between the fixing frame and the filter. One end of the fixed shaft is fixedly connected to the center of the fixing frame, and the other end is fixedly connected to the fan.

[0013] Furthermore, the first magnet and the second magnet attract each other.

[0014] Furthermore, a battery is provided inside the cavity, and a number of equidistant inner cavities are provided inside the four sides of the packaging box body, and a heating tube is provided inside each of the inner cavities.

[0015] Furthermore, each group of the fixed structure includes through cavity one, through cavity two, magnet one and magnet two. Through cavity one is provided on the top of the packaging box body, through cavity two is provided at a position corresponding to through cavity one on the bottom of the top cover, magnet two is provided inside through cavity one, and magnet one is provided inside through cavity two.
