Description

An adsorption type portable refrigerated transport box

technical field

The utility model relates to the field of refrigerated transport equipment, in particular to a multifunctional refrigerated transport box used in the field of low-temperature logistics of perishable products.

Background technique

With the improvement of living standards, people have higher and higher requirements for the quality and safety of fruits, vegetables and meat. However, under the current conditions, not only the post-harvest processing technology of agricultural products in my country is relatively weak and the production and sales areas are scattered, but also the number of refrigerated vehicles is insufficient. The imperfect infrastructure of cold chain logistics obviously contradicts this demand of people, so it is imminent to transport goods at low temperature and long distance effectively, reliably and economically. Various solutions have been proposed to solve this problem, and the refrigerated transport box is the most representative one among them. At present, the design of the refrigerated transport box mainly lies in the structural design of the box body. For example, a patented refrigerated transport box (2015208698257) designed a refrigerated transport box with a box body and a cover that matches it, and a patented royal jelly refrigerated transport box (2015201316779 ) designed a refrigerated transport box with a card slot that can be embedded in the isolation plate of the royal jelly bottle, and patented a liftable refrigerated transport box (2015202001526) disclosed a liftable refrigerated transport box, and patented a blood refrigerated transport box (2015201107449) discloses a blood refrigerated transport box with upper and lower layers of pull-out storage boxes in the box, and a patented medical refrigerated transport box (2010200223613) discloses a medical refrigerated transport box, a patented fruit and vegetable fresh-keeping refrigerated transport box ( 200920048784X) discloses a fresh-keeping refrigerated transport box for fruits and vegetables. These refrigerated boxes do not consider the cooling source of the refrigerated box, and cannot play the role of constant temperature in the actual process. The patent for a refrigerated transport box with its own cold source (2014107463729) discloses a refrigerated transport box using semiconductor refrigeration, which can effectively provide cooling capacity during transportation and play a constant temperature role, but cannot adjust the temperature, and the cooling capacity too small. Aiming at the problems that the temperature in the transport box cannot be adjusted and the cooling capacity is too small, the utility model proposes an adsorption-type portable refrigerated transport box.
