It is located on the outside of the collection rack 3 to facilitate the placement and removal of the storage box 14. A protective plate 4 is also provided on the top surface of the storage box 14 to prevent the entry of external impurities. The storage box 14 is placed in the collection rack 3, and a positioning piece 13 is connected to the storage box 14. The bottom side of the storage box 14 is movably connected to the pull rack 12. A collection chamber 16 is opened in the fixed shell 2, and a piston 9 is movably connected in the collection chamber 16. An annular cooling strip 5 is also installed on the rear cover plate 1.

[0023] Specifically, the fixed shell 2 is located at the center position of the outer side of the rear cover plate 1, and a plurality of support rods 6 are installed in a ring between the fixed shell 2 and the rear cover plate 1. Annular cooling strips 5 are connected between the support rods 6. The annular cooling strips 5 and the support rods 6 are connected by a pipeline to act on the introduction of liquid, and the effect of heat absorption and cooling can be achieved through the temperature difference between the liquid and the working environment.

[0024] Furthermore, the collecting frame 3 is fixedly mounted on the top surface of the fixed shell 2, and a guide port is opened on the bottom side of the collecting frame 3. A pull frame 12 is movably connected in the guide port. A filter element is installed in the pull frame 12 to filter the collected liquid. One end of the pull frame 12 passes through the outside of the collecting frame 3 to facilitate the replacement of the filter element. The guide port is connected to the collecting chamber 16, and a guide inclined plate 15 is obliquely installed between the inner walls of the collecting frame 3 to facilitate the unified collection of the liquid. The bottom ends of the guide inclined plates 15 are located on both sides of the top of the guide port.

[0025] In this embodiment, a support frame 11 is fixedly installed on the rear side surface of the fixed shell 2, a pull rod 7 is fixedly installed on one side of the piston 9, and the other end of the pull rod 7 passes through the outside of the fixed shell 2. An extrusion sheet 17 is welded and installed on the outer surface of the pull rod 7, and its limit is located on the outside of the fixed shell 2. The pull rod 7 moves and connects between the fixed shell 2 and the support frame 11. An extrusion spring 10 is installed between the extrusion sheet 17 and the support frame 11 to act on the piston 9 to continuously squeeze the liquid. A support frame 11 is fixedly installed on the rear side surface of the fixed shell 2, a pull rod 7 is fixedly installed on one side of the piston 9, and the other end of the pull rod 7 passes through the outside of the fixed shell 2 to act on the movement of the piston 9. An extrusion sheet 17 is welded and installed on the outer surface of the pull rod 7, and its limit is located on the outside of the fixed shell 2. The pull rod 7 moves and connects between the fixed shell 2 and the support frame 11. An extrusion spring 10 is installed between the extrusion sheet 17 and the support frame 11 to act on the piston 9 to continuously squeeze the liquid.

[0026] Working principle: When the rear cover 1 is placed in the air for a long time, the desiccant will absorb the water vapor in the air, which will drip from the storage box 14 after absorption, flow out from the guide port through the guide inclined plate 15, and then be filtered by the filter element. After filtering, the liquid flows into the collection chamber 16 for storage. When cooling is required, the pull rod 7 is pulled backwards. At this time, the extrusion spring 10 will be compressed, and the piston 9 will move backwards. The liquid stored in the collection chamber 16 will enter the front side of the piston 9 from the through hole, and then the pull rod 7 is released. Under the action of the extrusion spring 10, the piston 9 will be squeezed forward. Due to the closed liquid of the one-way valve, it cannot enter the through hole. Under the squeezing of the piston 9, the liquid will enter the support rod 6 from the liquid separation port 8 and finally flow into the annular cooling strip 5. At this time, the liquid will absorb the temperature around the rear cover 1 to achieve the cooling effect.
