[0024] Among them, anti-freezing layer 8 is polystyrene resin layer 13, and the outer side and the inner side of polystyrene resin layer 13 are respectively equipped with outer rock wool layer 14 and inner rock wool layer 12, polystyrene resin layer 13 is made of polystyrene resin, polystyrene resin has good heat preservation performance, and outer rock wool layer 14 and inner rock wool layer 12 are both made of rock wool, and rock wool also has certain heat preservation performance, so three layers are combined, to effectively improve the heat preservation and anti-freezing effect of anti-freezing layer 8.

[0025] The heat exchange mechanism comprises a heat dissipation hole groove 10, which is arranged at the bottom of the mounting hole 11. The bottom of the mounting shell 4 is provided with a bottom plate 16 for supporting the mounting shell 4. The top of the bottom plate 16 is provided with a plurality of blocking heads 15 distributed at equal distances and fixed by bolts.
