Description
CROSS-REFERENCE TO THE RELATED APPLICATIONS

This application is based upon and claims priority to Chinese Patent Application No. 202211684525.2, filed on Dec. 27, 2022, the entire contents of which are incorporated herein by reference.


TECHNICAL FIELD

The present invention relates to the technical field of fresh product cold chain preservation, and in particular to a fresh product cold chain distribution device and a distribution method.


BACKGROUND

In the modern logistics industry, fresh food transportation accounts for a large proportion. Fresh food, prone to quick spoilage, requires a whole process of cold chain transportation and distribution. With the rapid construction of China's cold chain logistics system, the whole process of cold chain logistics from the production end to the urban distribution center has been essentially solved. However, there are still many problems to be solved in the distribution mode and equipment from the urban distribution center to the consumer. The existing fresh product cold chain distribution method involves coordinating delivery times between the courier and the consumer, or the courier placing the fresh product in regular logistics pick-up lockers or community stores for the consumer to pick up. Cold chain distribution relies on insulated bags and foam insulated boxes, and fresh products are subject to passive insulation and warming processes, which require high delivery efficiency. This delivery method, while consuming a large amount of manpower, makes it difficult to guarantee the quality of fresh products. The main problems with the existing fresh product cold chain distribution are as follows: 1. the lack of a self-service device with multi-temperature zones, low energy consumption, and low cost along with a solution for fresh produce cold chain distribution. If a shared community refrigerator is used, firstly, the requirement of simultaneously preserving and freezing products in multi-temperature zones cannot be realized; secondly, the operation must be prolonged to keep a low temperature, and the energy consumption is bound to be high; thirdly, the equipment is expensive and the investment cost is high, and low utilization rate will lead to higher operation cost; fourthly, the foam insulated logistics box placed in the refrigerator must be unpacked to ensure low temperature of fresh products, which is easy to cause logistics confusion and fresh products contamination. 2. The logistics boxes used for cold chain delivery of fresh products lack refrigeration capacity and can only carry out passive insulation, and the temperature is increased in the distribution and storage processes, so that the distribution time is short, and the quality of the fresh products cannot be guaranteed. 3. The insulated logistics box for fresh product cold chain delivery is made of plastic foam, which is disposable and easily broken, and extensive use for a long time will cause serious environmental pollution.


SUMMARY

Aiming at the shortcomings in the prior art, the present invention aims to provide a fresh product cold chain distribution device and distribution method to achieve self-service, low energy consumption, and multi-temperature storage in the cold chain distribution, meet the requirements of long-term and constant-temperature refrigeration for fresh products, promote the recycling of the insulated logistics box, improve the distribution efficiency of fresh products, ensure the best refrigeration effect of fresh products in the whole process, improve product quality, and reduce environmental pollution.


In order to achieve the purposes described above, the technical solution adopted by the present invention is as follows: a fresh product cold chain distribution device, comprising at least one refrigeration logistics box and a self-service fresh product pickup cabinet. The refrigeration logistics box comprises a box body, a box cover, a side cover, a quick-connection plug board, a refrigeration device, a temperature selection switch, and an identification; the box body comprises a positioning slot and air guide grooves; the refrigeration logistics box is matched and fixedly placed in the self-service pickup cabinet unit cell through the positioning slot and the limiting lock in the self-service pickup cabinet unit cell.

The self-service fresh product pickup cabinet 1 comprises a cabinet body 11, a side panel 12, a back panel 13, a top panel 14, a door panel 15, an air channel cover panel 16, an exhaust channel 101, an inlet channel 102, a scanner 17, a touch display screen, 18 and a control panel 103; the cabinet body 11 comprises a plurality of unit cells, each unit cell is provided with a door panel 15, an electric door lock 151, a contact power supply plug 19, a limiting lock 100, inlet holes 1022 of the self-service pickup cabinet unit cell, and exhaust holes 1011 of the self-service pickup cabinet unit cell, and an inlet channel 102 and an exhaust channel 101 are provided between each set of unit cells.


In the present invention, the refrigeration logistics box 2 equipped with a refrigeration device 24 is used to store fresh products requiring low-temperature preservation during the distribution process. The temperature of the refrigeration logistics box 2 is adjusted through the temperature selection switch 232, and the refrigeration logistics box 2 is continuously powered during the distribution by connecting the power supply interface on the quick-connection plug board 231 of the refrigeration logistics box 2 to the power supply end of the delivery vehicle. In the delivery terminal, the courier scans the identification 25 of the refrigeration logistics box using the scanner 17 on the self-service fresh product pickup cabinet 1 and stores the refrigeration logistics box 2; in the unit cell, the refrigeration logistics box 2 is positioned and fixed by the limiting lock 100, and the refrigeration logistics box 2 is continuously powered through the contact power supply plug 19 and the elastic contact point on the quick-connection plug board 231 of the refrigeration logistics box 2; the heat released by the refrigeration logistics box 2 is discharged through the air channel between unit cells to cool down the unit cell and reduce energy consumption. The self-service fresh product pickup cabinet 1 can store the refrigeration logistics box 2 for a long time, allowing consumers to freely pick up the products. After the consumer takes the fresh products and returns the refrigeration logistics box 2, the courier can retrieve and reuse the refrigeration logistics box 2.


In the present invention, the refrigeration logistics box 2 equipped with a refrigeration device 24 is used to store fresh products requiring low-temperature preservation during the distribution process. In the delivery terminal, the refrigeration logistics box 2 filled with fresh products is stored in one of the plurality of unit cells on the self-service fresh product pickup cabinet 1, and the refrigeration logistics box 2 is continuously powered through the contact power supply plug 19 and the elastic contact point on the quick-connection plug board 231. By doing so, the temperature during the whole delivery process remains constant, and consumers can pick up the products freely, which ensures the product quality and greatly improves the convenience.


After receiving the delivery order, the courier puts the refrigeration logistics box 2 containing the products in the rear box of the battery car. In order to guarantee the continuous refrigeration in the distribution process and during the storage period, elastic contact points 2313 and a storage battery standard plug 2314 are provided on the quick-connection plug board 231 of the side cover 23 of the refrigeration logistics box (referring to FIG. 3). During the delivery process, the refrigeration logistics box is powered by connecting the storage battery standard plug to the battery car, and the temperature selection switch 232 is turned on at the same time.
