Automatic air supplementing type fresh food transportation box

Abstract

The invention discloses an automatic air supplementing type fresh food transportation box which comprises a box body. An upper cover abuts against an opening in the upper end of the box body, an exhaust pipe is arranged at the upper end of the upper cover in a penetrating manner, a base is fixed to the bottom of the box body, and two pumping pipes extending into the box body are arranged at the upper end of the base in penetrating and inserting manners; and piston rods are arranged at the upper ends of the two pumping pipes in a penetrating manner, floating balls are fixed to the upper ends ofthe two piston rods, and air pumping pipes communicating with the interior of the box body are arranged on the side walls of the two pumping pipes in penetrating and inserting manners. The automaticair supplementing type fresh food transportation box has the advantages that the floating balls are arranged, when the water surface fluctuates in the transportation process, the floating balls move up and down along with the water surface, then the piston rods are driven to move, external gas is pumped by the piston rods, enters the box body through the pumping pipes and the air pumping pipes andis directly filled into water, air in the water is supplemented, and the survival rate of fresh food is increased.

Description

technical field [0001] The invention relates to the technical field of fresh food transportation, in particular to an automatic air supply type fresh food transportation box. Background technique [0002] With the acceleration of economic globalization, fresh food e-commerce has become very popular at present, and some fresh seafood can also go to tables in inland areas. In the process of fresh food logistics, in order to ensure the survival rate of fresh food, usually It is necessary to transport fresh food into the water, and at the same time, it is necessary to ensure good air permeability. However, there is usually a big contradiction in ensuring moisture and air permeability at the same time; [0003] Most of the existing transport boxes are directly sealed, or have a certain amount of small holes, which can avoid large water damage caused by road bumps, but the speed of gas exchange with the outside is low, resulting in reduced air content in the water and affecting fr...
