An air intake cylinder 9 is arranged on the top of the protective plate 7. The air intake cylinder 9 is provided with an air valve. The air intake cylinder 9 is connected to the upper insulation shell 1. A filter screen 10 is bolted to the top of the air intake cylinder 9. An air intake fan 11 is fixed in the air intake cylinder 9. A heating element 12 is fixed in the air intake cylinder 9. A heat pipe 12, a temperature sensor 13 is fixed in the upper insulation shell 1, an upper insulation layer 14 is arranged in the upper insulation shell 1, and the upper insulation layer 14 is fixed in the upper insulation groove 4, a lower mounting plate 15 is arranged on the top of the lower insulation shell 2, and a plurality of threaded through holes are equidistantly arranged on the lower mounting plate 15, the lower insulation shell 2 is provided with two lower sealing grooves 16, and the two lower sealing grooves 16 are symmetrical about the vertical center line of the lower insulation shell 2, and the lower sealing grooves 16 are provided with lower sealing rings 17, the lower insulation shell 2 is provided with a lower insulation groove 18, a lower insulation layer 19 is arranged in the lower insulation shell 2, and the lower insulation layer 19 is located in the lower insulation shell 2, the lower insulation shell 2 is provided with ventilation grooves 20, and a plurality of ventilation nets 21 with high mesh density are equidistantly arranged in the ventilation grooves 20.

[0025] Working principle: manually pick up the upper insulation shell 1 and the lower insulation shell 2, align the threaded through holes of the upper mounting plate 3 and the lower mounting plate 15, and fix the upper mounting plate 3 and the lower mounting plate 15 with bolts. Before fixing the upper insulation shell 1 and the lower insulation shell 2 with bolts, a sealing ring must be placed between the upper insulation shell 1 and the lower insulation shell 2 in advance to ensure the sealing of the upper insulation shell 1 and the lower insulation shell 2. The upper insulation shell 1 and the lower insulation shell 2 are fixed with bolts. At this time, the upper sealing ring 6 and the lower sealing ring 17 are respectively in contact with the water inlet pipe and the water outlet pipe to ensure the sealing. When the temperature sensor 13 senses that the temperature between the upper insulation shell 1 and the lower insulation shell 2 is low, the heating tube 12 starts to generate Heat, the air valve opens, the air intake fan 11 starts, the air intake fan 11 draws external air into the air intake cylinder 9, and the heated air enters the upper protective shell 1 and the lower protective shell 2. The air in the upper protective shell 1 and the lower protective shell 2 can be discharged through the ventilation net 21 under the action of air pressure, and the heated air flows in the upper protective shell 1 and the lower protective shell 2 to achieve heating of the smart water meter and the water pipe. After the temperature sensor 13 reaches the appropriate temperature, the air intake fan 11 stops running. At this time, the valve is closed, and the upper insulation layer 14 and the lower insulation layer 19 can slow down the loss of heat. When the temperature of the smart water meter drops to a critical point, the temperature sensor 13 triggers the repetition of the above work.
