Description

Detachable cold-charged phase change cold storage fresh box

technical field

The invention relates to a fresh-keeping box, in particular to a detachable cold-filling type phase-change cold-storage fresh-keeping box.

Background technique

With the rapid development of the Internet of Things + e-commerce, fresh fruits and vegetables and frozen foods have also entered e-commerce and express logistics products. At present, fresh fruits and vegetables and frozen foods are transported by couriers to For end customers, foam plastics or adding ice cubes are often used. This method has disadvantages such as deterioration of the transported goods due to improper heat preservation, and partial frostbite of fruits and vegetables due to adding ice cubes. Although ice cubes are the simplest and most common phase change cold storage materials, when used alone, ice cubes are disposable consumables and cannot be reused many times, resulting in unnecessary waste. At present, a variety of phase change cold storage materials have been researched and developed, but few phase change cold storage materials have been applied to products.

Contents of the invention

In view of the defects in the prior art and the limitation of the use of phase change cold storage materials, the purpose of the present invention is to provide a detachable and cold-filled phase change cold storage fresh box that can meet the short-distance preservation and transportation of goods and is convenient to carry.

In order to achieve the above object, the present invention adopts the following technical solutions: a detachable and cold-filled phase-change cold storage fresh box, including a box body and a box cover, box grooves are opened on the four sides of the box body, and the box body A detachable cold-charged phase-change cold storage plate is inserted into the body tank, and a temperature display screen is installed on one side of the box body to display the internal temperature of the phase-change cold storage fresh-keeping box.

The four sides of the box are fastened together with the box cover by fastening hooks.

The cold-charging phase-change cold storage plate is detachably connected to the box cover, which is used to facilitate the removal of the phase-change cold storage plate for cold charging.

The cold-charged phase-change cold-storage plate is filled with phase-change cold-storage materials selected according to the cold-storage temperature to form multiple temperature sections.

The beneficial effects of the present invention are:

After the detachable phase-change cold storage plate is inserted into the box body groove of the detachable cold-charged phase-change cold storage fresh-keeping box of the present invention after phase-change cold storage, it has a good heat preservation effect and is very suitable for the transportation of a small amount of fresh-keeping goods Low-temperature distribution, low cost, not subject to geographical restrictions, can be used repeatedly, low cost, safe and hygienic.

Description of drawings

Fig. 1 is a three-dimensional exploded schematic diagram of the detachable cold-filling phase-change cold-storage fresh-keeping box of the present invention.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, a detachable cold-charged phase-change cold storage fresh box includes a box cover 1, a box body 2, a box body groove 3, a cold-charged phase-change cold storage plate 4, a temperature display 5, a fastening Grab hook 6.

The box cover 1 is fastened on the box body 2 through four fastening hooks 6, the other four sides of the box body 2 except the bottom surface are all provided with box body grooves, and the detachable cold charging type phase change cold storage plate 4 is inserted into the In the tank of the box body 2 , the temperature display screen 5 is located in the center of one side of the box body 2 . The detachable cold-charged phase-change cold-storage fresh box of the present invention can be used by inserting the cold-charged phase-change cold-storage plate 4 into the tank 2 of the box body.

The box cover 1 is fastened together with the box body 2 by the fastening hook 6, which is convenient and quick to open and close without affecting its thermal insulation effect. The other four surfaces of the box body 2 except the bottom surface are all provided with grooves, into which the cold-charging type phase-change cold storage plate 4 can be inserted. The detachable cold-charging phase-change cold storage plate 4 can be conveniently taken out to charge cold, and the phase-change cold storage plate of different phase-change cold storage materials can also be exchanged according to different transport items. The detachable cold-charged phase-change cold storage plate is equipped with phase-change cold storage materials. The phase-change cold-storage material filled inside the detachable cold-charged phase-change cold storage plate can be selected according to specific requirements, and there are multiple temperature ranges. The temperature display screen 5 can display the inside of the phase change cold storage fresh-keeping box.

After the coolness of the cold-charged phase-change cold storage plate 4 is released, it can be removed and placed in a cold storage, freezer, etc. for charging, and the cold-storage material stored in the cold-charged phase-change cold storage plate is used to store the coldness, and then it can be stored during transportation. Slowly release the cooling capacity to ensure the freshness of the transported items.

The shape of the detachable cold-filling type phase-change cold storage fresh-keeping box of the present invention is made into a cube. The box cover and the box bottom are made of PVC braided mesh cloth, PE board and PU insulation material from the outside to the inside. From the outside to the inside, the four sides are PVC braided mesh cloth, PE board, and detachable phase change cold storage board. The temperature display screen measures the temperature through the temperature sensor installed in the fresh-keeping box and displays it on the display screen. The phase-change cold storage material used in the specific embodiment of the present invention is octanoic acid. The initial melting temperature of octanoic acid is 9.646°C, the peak melting temperature is 14.407°C, and the latent heat of melting is 116.945J/g; the initial solidification temperature is 5.399°C, and the latent heat of solidification is 115.463 J/g. A total of 2kg of octanoic acid is installed in the four cold-charged phase-change cold storage plates. The cooling rate is 0.0125°C/min after testing, and it takes about 4.88 hours to heat up from the freezing point to the melting point, which can meet the needs of short-distance transportation. The temperature in the box is maintained at 0-10°C for about 5 hours.

When the detachable cold-charged phase-change cold storage fresh box is in use, different detachable phase-change cold storage plates can be selected according to the temperature requirements of different transport products, and the phase-change cold storage plates are equipped with different types of phase-change cold storage materials.
