After the drying is completed, the processor will control the switch 20 to open, and the desiccant in the drying cylinder 3 will pass through the feed pipe under the action of gravity 17 enters the heating chamber 9 from the second feed port 10, and then the processor will control the motor 22 and the cylinder 25 to be energized. The cylinder 25 drives the scraper 26 to move down through the air rod, so that the scraper 26 is in contact with the desiccant. 22 will drive the threaded block 24 through the screw 23 to move, and the threaded block 24 will drive the scraper 26 to move from left to right through the air cylinder 25, so as to spread the accumulated desiccant on the mesh plate 12, thereby expanding the surface area of ​​the desiccant. Makes the desiccant easier to heat, and then the blowing device 13 is activated. The blowing device 13 blows air into each thermal spray head 14. The air is heated in the thermal spray head 14. The multiple thermal spray heads 14 can be The desiccant is fully heated, and the moisture absorbed by the desiccant becomes water vapor after being heated and then leaves the desiccant, and then the water vapor is discharged from the exhaust port 16 to the outside of the lock housing 1 through the exhaust pipe 15. After the desiccant is dehydrated, the conveying device 19 The dehydrated desiccant will be output from the second outlet 11 to the first inlet 8 through the feed pipe 18, and finally the dehydrated desiccant will re-enter the drying cylinder 3, thereby realizing the circulating drying of the humid air . By drying the air in the lock case 1, it is possible to prevent the damp air from causing short circuits and leakage in the circuit, prevent the electronic components inside the lock case 1 from being damaged by moisture, and improve the service life of the smart lock.
