Therefore, phase change materials are usually used in fields such as thermal energy storage and temperature control. They can be divided into inorganic phase change materials and organic phase change materials. The phase change material packaging box is a structure used to contain and protect the phase change material, which generally has good sealing, temperature resistance and thermal conductivity.

[0003] However, the existing phase change material packaging box has the following problems when used:

[0004] For example, a phase change material packaging box with a publication number of CN205266110U and an authorization announcement date of 20160525, although the device can be opened and closed by screws, multiple screws need to be turned when the device is opened and closed, which makes the opening and closing of the device inconvenient, reducing the convenience of using the phase change material packaging box. At the same time, when the phase change material is packaged in the packaging box, it is not convenient to maintain a vacuum environment for the phase change material, which affects the preservation effect of the phase change material.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original phase change material packaging box. Utility Model Content

[0023] The inner wall of the rotary sleeve 7 is movably provided with a lifting rod 8, and the outer wall of the rotary sleeve 7 on the side of the blocking plate 602 is rotatably connected with a sealing ring 15, and a suction air duct is opened on the sealing ring 15, and the sealing ring 15 is matched with the blocking plate 602, so that the blocking plate 602 can block the suction air duct on the sealing ring 15 under the push of the adjusting rod 601, or the adjusting rod 601 drives the blocking plate 602 away from the suction air duct on the sealing ring 15 to open it, and the lower end of the lifting rod 8 is fixedly connected with a pressing plate 9, and a clamping rod 10 is fixed parallel to the side of the upper surface of the pressing plate 9, the bracket 4 and the clamping rod 10 are connected through, the positioning frame 5 and the rotary sleeve 7 form a rotating structure, and the rotary sleeve 7 and the lifting rod 8 are threadedly connected, so that when the pressing plate 9 moves, the pressing plate 9 drives the clamping rod 10 to slide relative to the bracket 4, thereby improving the stability of the movement of the box cover 12, and facilitating the user to rotate the rotary sleeve 7 to make the lifting rod 8 move vertically, thereby driving The pressing plate 9 and the box cover 12 move, and at the same time, a pressing rod 11 is fixedly installed on the lower surface of the pressing plate 9, and the lower end of the pressing rod 11 is fixedly connected to the box cover 12. The lifting rod 8, the pressing plate 9, the pressing rod 11 and the box cover 12 are all hollow structures, which is conducive to sucking the air in the packaging box body 1 through the hollow lifting rod 8, the pressing plate 9, the pressing rod 11 and the box cover 12. A sealing ring 13 is bonded to the outer wall at the edge of the box cover 12, and a clamping column 14 is fixed at both ends of the lower surface of the box cover 12. The packaging box body 1 and the box cover 12 are slidably connected, and the packaging box body 1 and the sealing ring 13 are fitted.

[0024] When the phase change material is used to encapsulate the box body, Figure 1-2 and Figure 4 As shown, the user pours the phase change material into the packaging box body 1, and then the user pushes the bracket 4 to rotate so that the bracket 4 drives the box cover 12 to move above the packaging box body 1, and then the user rotates the rotary sleeve 7, and then the lifting rod 8 moves downward relative to the rotary sleeve 7, and then the lifting rod 8 drives the pressing plate 9 to move downward, and as the pressing plate 9 moves, the pressing plate 9 drives the clamping rod 10 to slide relative to the bracket 4, and then the pressing plate 9 drives the pressing rod 11 to move downward, and then the pressing rod 11 drives the box cover 12 to move downward, and then as the rotary sleeve 7 continues to rotate, the box cover 12 is finally inserted into the packaging box body 1, and at the same time, the box cover 12 squeezes the sealing ring 13 to fit the packaging box body 1, and as the box cover 12 moves, the box cover 12 drives the clamping column 14 to insert into the clamping sleeve 3, and at this time the phase change material is loaded into the packaging box body 1;

[0025] Then as Figure 1-Figure 5As shown, the user rotates the adjusting rod 601, and then the adjusting rod 601 moves on the positioning frame 5 through the thread.

At this time, the packaging box body 1 is released from the vacuum state. Then the user rotates the rotary sleeve 7 in the opposite direction to make the box cover 12 disengage from the packaging box body 1. Next, the user rotates the bracket 4 so that the bracket 4 drives the box cover 12 away from the packaging box body 1, thereby completing the opening of the device. When the device is in use, the heat dissipation fins 2 increase the contact area between the packaging box body 1 and the phase change material, thereby improving the efficiency of the phase change material in absorbing or releasing heat.
