A main heat-conducting plate 5 is symmetrically connected to the inner side of the main heat insulation layer 4, and a main heat insulation ring 8 is fixedly connected to the bottom of the inner cavity of the shell 3. A secondary heat-conducting plate 7 is fixedly connected to the upper surface of the main heat insulation ring 8, and a sampling bottle 6 is movably connected to the upper surface of the secondary heat-conducting plate 7. Simultaneously, a secondary screw thread is fixedly connected to the lower end of the outer side of the shell 3. The inner cavity of the secondary screw-in cylinder 9 is fixedly connected to the bottom shell 10, and the inner cavity of the bottom shell 10 is fixedly connected to the secondary heat insulation layer 11. The interior of the secondary heat insulation layer 11 is movably connected to the refrigeration box 12, and the upper surface of the refrigeration box 12 is movably connected to the secondary heat insulation ring 15. A through-hole is opened in the middle of the upper surface of the refrigeration box 12, and a heat-conducting column 14 is slidably connected in the through-hole. The lower end of the heat-conducting column 14 is fixedly connected to the bottom of the inner cavity of the refrigeration box 12 by a magnet 13, and the upper end of the heat-conducting column 14 passes through the through hole opened in the lower surface of the shell 3 and abuts against the secondary heat-conducting plate 7.

[0019] In this embodiment, a sampling bottle 6 containing a water sample is inserted into the housing 3, so that the outer side of the sampling bottle 6 can respectively adhere to the inner side of the main heating plate 5 and the main heating layer. Then, the main screw connector 2 is screwed into the inner cavity of the housing 3, so that the cap 1 can be fixedly connected to the upper surface of the housing 3, and the cap of the sampling bottle 6 can abut against the buffer plate 17 inside the main screw connector 2 to fix the sampling bottle 6. Then, the refrigeration box 12 after cooling is inserted into the bottom shell 10, and the ice cubes frozen inside the refrigeration box 12 can fully contact the lower end of the heat-conducting column 14, so that the heat-conducting column 14 can be fixedly connected to the refrigeration box 12. The upper end of the heat-conducting column 14 is embedded in the through hole opened on the lower surface of the housing 3. Furthermore, the outer side of the bottom shell 10 can be screwed into the interior of the auxiliary screw cylinder 9. Rotating the bottom shell 10 causes the cooling box 12 and the heat-conducting column 14 to move upward synchronously under the action of the screw structure. The upper end of the heat-conducting column 14 can then abut against the lower surface of the auxiliary heat-conducting plate 7. At this time, the heat on the surface of the sampling bottle 6 can be transferred to the ice in the cooling box 12 through the main heat-conducting plate 5, the auxiliary heat-conducting plate 7, and the heat-conducting column 14, thereby ensuring that the sampling bottle 6 inside the shell 3 is kept at a low temperature. This can suppress the activity of substances inside the sampling bottle 6 and ensure the accuracy of subsequent testing.

The bottom housing 10 can be made of polyvinyl chloride material to further enhance the heat insulation effect. The anti-slip block on the outer side of the bottom housing 10 can help reduce the chance of slipping when rotating.
