In the past, the car carrying cold drinks had to be covered with a quilt, which followed the insulation method of placing quilts on wooden boxes that used to sell popsicles. Covering the refrigerator with a quilt can further improve the thermal insulation effect, isolate the convection of hot air, improve the thermal insulation performance, and prevent the temperature of the items in the refrigerator from changing rapidly. The quilt can keep warm, not just warm, because the quilt mainly delays the heat exchange with the outside world, so if you wrap something cold with the quilt in summer, it can also make it less likely to get hot and wrap the ice cream, and it won't melt quickly.

Nowadays, refrigerated trucks play a central role in cold chain logistics, mainly in ensuring food safety and fresh food quality. The utility model relates to a cold drink selling device, in particular to a cold drink selling car. Comprises a chassis car and a carriage, wherein the carriage is arranged as a sales room and a power generation room; The sales room is equipped with an ice cream machine, a juicer and a refrigerator. The generator set and power distribution cabinet are arranged in the generator room. Compared with the prior art, the invention has strong maneuverability. In addition to the ice cream machine, juicer, refrigerator and other cold drink production and storage equipment, the carriage is also equipped with an independent power generation system, including generator sets and power distribution cabinets, which can meet the long-term work requirements. At the same time, there is also an output junction box under the carriage, which has the function of emergency power output and is more practical for the whole vehicle.

With the approach of midsummer, people's demand for cold drinks is getting stronger and stronger, and the cold drink market is showing a hot trend. Various summer heat dissipation products such as ice cream, fruit juice and frozen fruit are more and more popular. In this context, there are various cold drink shops on the street.

Because of the low investment and quick effect, the mobile cold drink truck is more suitable for busy commercial streets, schools or large community entrances, seaside, parks and other places where people are concentrated. However, the existing mobile cold drink truck is simple in structure, low in maneuverability, difficult to pass through some complicated sections, and unable to work in the field for a long time without an independent power supply system. At the same time, the existing mobile cold drink truck can not achieve more functions besides providing cold drinks, such as providing emergency power. Therefore, there are some limitations in practical application.
