[0025] Side strips 61 are installed on both sides of the front end of the top block 64 and inside the distribution box 1. A slide groove 62 is provided at the side end of the side strip 61. A desiccant 68 is installed at the top end of the slide groove 62. Limiting grooves 63 are provided on the front and rear sides of the slide groove 62 and inside the body of the side strip 61. When the vacuum pump 67 is operating, the air at the upper end of the distribution box 1 is processed by the desiccant 68 to dehumidify the air. When the air is discharged through the vacuum pump 67, the air at the lower end of the distribution box 1 can be discharged through the heat dissipation holes 3.

[0026] The storage component 7 includes a moving bar 71 and a storage groove 72 opened at the top of the moving bar 71. Side blocks 75 are installed on both sides of the moving bar 71.
