Anti-rot type transport case for fruit and vegetable transportation

Abstract

The invention discloses an anti-rot type transport case for fruit and vegetable transportation. The anti-rot type transport case comprises a shell and a triggering mechanism. A triggering cavity, a containing cavity and two refrigerating cavities are formed in the shell. The triggering cavity is located above the containing cavity. The two refrigerating cavities are located below the containing cavity. The triggering mechanism comprises two piston plates symmetrically connected in the triggering cavity in a sliding manner. The two piston plates communicate with the inner walls of the two sidesof the triggering cavity through two connecting springs respectively. A balancing weight is arranged in the space, located between the two piston plates, of the triggering cavity. In the using process of the transport case, fruits and vegetables can be subjected to low-temperature freshness preservation, and the fruits and vegetables can be fully moisturized without an external power source or other electric appliances; and meanwhile, a moving mechanism is further arranged, and the freshness preservation range is large during low-temperature freshness preservation.

Description

technical field [0001] The invention relates to the field of fruit and vegetable transportation, in particular to an anti-rot transport box for fruit and vegetable transportation. Background technique [0002] Fruit and vegetable transportation refers to the transportation of fruits, and during the transportation of fruits, we generally need to keep them fresh at low temperature to avoid rotten fruits during long-distance transportation; [0003] After retrieval, the application number is CN201711242300.0, which is a patent application document named a fruit and vegetable transport box, including a box body, a refrigeration room, a control room and a fresh-keeping room are arranged in the box, and a sealable inlet is provided on the side wall of the refrigeration room. There is a heat insulation layer fixed on the side wall of the refrigeration room, and a closeable material feeding port is provided on the side wall of the fresh-keeping room; a piston that can slide along th...

[0003] After retrieval, the application number is CN201711242300.0, which is a patent application document named a fruit and vegetable transport box, including a box body, a refrigeration room, a control room and a fresh-keeping room are arranged in the box, and a sealable inlet is provided on the side wall of the refrigeration room. There is a heat insulation layer fixed on the side wall of the refrigeration room, and a closeable material feeding port is provided on the side wall of the fresh-keeping room; a piston that can slide along the side wall of the control room is installed in the control room, and a control valve is fixed on the side wall of the refrigeration room. The air outlet one-way valve connected to the room, the side wall of the fresh-keeping room is fixed with an inlet pipe and an inlet one-way valve connected with the control room, and the inlet pipe is connected with the inlet one-way valve. The level of the middle bottom is relatively high, which makes it difficult for the water entering the bottom of the fresh-keeping chamber to enter the refrigeration chamber under pressure, and the water spray nozzle is always in a fixed state during the whole process. The scope of water spraying is limited, and it cannot fully preserve the freshness of fruits and vegetables in the safe room;
