[0030] Through the above technical solution, the granular moisture absorbent 9 can be easily replaced by setting the discharge slot 13 .

[0031] The supporting mesh plate 8 is tilted, and the tilt angle of the supporting mesh plate 8 is between 25 degrees and 75 degrees.

[0032] Through the above technical solution, the arrangement of the supporting mesh plate 8 is conducive to the discharge of the granular moisture absorbent 9 and the passage of gas.

[0033] The inner cavity of the heating tube 7 is fixedly installed with a cross fixing frame 15, an electric heating wire layer 17 and a barrier screen 18 in sequence from the outside to the inside. A driving motor 14 is fixedly installed on one side of the cross fixing frame 15, and a pushing impeller 16 is fixedly connected to the output end of the driving motor 14.

[0034] Through the above technical scheme, through the setting of the heating tube 7, when the driving motor 14 drives the pushing impeller 16 to rotate, the dehumidified gas can be blown to the heated electric heating wire layer 17, and after the gas is heated, it is sent into the box body 1 through the barrier mesh plate 18, thereby avoiding the situation where the temperature in the box body 1 is too low and frost occurs.

Then, after the device is powered on through the external power socket, the electric heating wire layer 17 in the heating tube 7 is heated. At the same time, the driving motor 14 drives the pushing impeller 16 to rotate, so as to guide the gas in the box body 1 to enter the fixed cover 5 through the air guide hole 12. After the gas passes through the evenly dividing mesh plate 11, the granular desiccant 9 and the supporting mesh plate 8, the gas is dehumidified. Then, the rotating pushing impeller 16 can blow the dehumidified gas to the heated electric heating wire layer 17. After the gas is heated, it is sent into the box body 1 through the barrier mesh plate 18, thereby avoiding the situation where the temperature in the box body 1 is too low and frost occurs, and when the humidity standard in the box body 1 is lowered, the appearance of frost is further suppressed, thereby ensuring the normal operation of the electrical circuit.
