Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food preservation, in particular to a fresh-keeping box. Background Art
[0002] The preservation of fruits and vegetables is an important part of storage. At present, the commonly used storage methods are chemical preservation, low-temperature storage, and controlled atmosphere preservation. Among them, chemical preservation is more commonly used, but it is accompanied by food safety issues. At present, the method of cold chain fruit and vegetable preservation is to mix a certain amount of oxygen and carbon dioxide gas for storage under low temperature conditions, but the key to the method is to control the reasonable gas ratio, which cannot eliminate the survival of harmful microorganisms at low temperatures. Chemical preservatives are used for immersion treatment, and there are many chemical components. Even if the purpose of preservation is achieved, it is difficult to ensure the safety of food.
[0003] At present, when fruits are stored in batches for preservation, large-capacity fresh-keeping boxes are needed for storage. When there are more fruits stored inside, the fruits will produce anaerobic respiration inside the fresh-keeping box, which will generate a certain amount of heat. When the heat is too high, it will increase the reproduction rate of anaerobic bacteria inside, causing the stored fruits to decay faster. At the same time, fruits will produce gases such as ethylene in a relatively high temperature environment, causing fruits and vegetables to mature quickly and are not easy to store for a long time.

The steering gear 1 is controlled to drive the sealing plate to block or open the cold air hole 2 according to the signal fed back by the temperature and humidity sensor 12, so as to control the amount of cold air entering the box body 6. A sealing cover is hingedly mounted at the top of the upper cover plate 5 at the opening of the receiving chamber 7. The hinge between the sealing cover and the upper cover plate has a certain damping. Insulation cotton is bonded to the sealing cover to maintain the temperature in the receiving chamber 7 and slow down the loss of cold air.

The control board 11 is a prior art and will not be described here. A battery is installed in the dustproof box 10, and the battery is connected to the power supply port on the expansion board 13 to power the entire system. The battery can be charged through the charging port, and a solar panel can also be set for outdoor use. The solar panel is connected to the battery through the expansion board 13 to store electricity for the battery.
[0030] The bottom end of the box body 6 is provided with a foot 17, and the foot 17 is used to prop up the bottom end of the box body 6 to provide sufficient ventilation space.
[0031] The ice crystal box needs to be replaced every 24 hours, and the program setting of the control panel 11 has a corresponding alarm prompt.
[0032] The main functions of the fresh-keeping box include: temperature control, humidity control, ultraviolet disinfection, timed air conditioning, network connection and real-time fresh-keeping status monitoring. The temperature and humidity sensor 12 can monitor the ambient temperature and humidity in the box body 6 in real time, and automatically adjust the temperature of the fresh-keeping box according to the different fresh-keeping requirements of different foods by changing the program settings of the control panel 11; the air circulation in the fresh-keeping box is adjusted by controlling the opening and closing of the fan 16, and the temperature is controlled by controlling the servo 1 to drive the sealing plate to intermittently block the cold air hole 2. During the use of the fresh-keeping box, the mobile phone software can be connected to the control panel 11 to monitor and adjust the temperature and humidity in real time, and record past data to achieve intelligent management and use. When using the fresh-keeping box, the relevant program parameters (the most suitable storage temperature and humidity) can be set in advance, and a variety of fresh-keeping modes for different foods can be set to meet the different fresh-keeping requirements of different foods.
