[0033] Combine Figure 2 and Figure 3 The fan 12 is fixedly connected to the inner walls of the two connecting shells 13, and two second slide rails 7 are fixedly connected to one side of the two connecting shells 13. A filter screen 6 is slidably connected between the two adjacent second slide rails 7. When the filter screen 6 is replaced, it is only necessary to move the filter screen 6 upward to take it out. At the same time, it moves within the second slide rail 7. The outer walls of the two filter screens 6 are penetrated and fixedly connected with two conical buckets 8. The conical buckets 8 increase the direction of air intake, so that air at different positions can enter the shell 2 faster. A continuous moisture absorption component is provided on one side of the outer wall of the shell 2, and two first support plates 9 are provided on one side of the continuous moisture absorption component. A splint 23 is fixedly connected to the top of the two first support plates 9. A desiccant 10 is slidably connected between the two adjacent splints 23 on the left and right.

[0034] Combine Figure 4The continuous moisture absorption component includes a second support plate 15, which is fixedly connected to the shell 2, and a motor 16 is fixedly connected to the top of the second support plate 15.
