As shown in fig. 2 and 5, when the second hinged door 21 rotates downward, the rope 34 is pulled to move downward, and after the direction of the rope 34 is changed by the fixed pulley 39, the other end of the rope 34 pulls the push plate 33 to move horizontally against the elastic force of the second spring 32, and the drying is pushed to pass through the third hinged door 29; in the process of moving the push plate 33 towards the storage box 4, the roller 38 rolls towards the storage box 4, and the roller 38 not only has a supporting effect on the push plate 33, but also reduces the friction force when the push plate 33 moves; the guide block 37 moves within the guide slot 36 to reduce the likelihood of the push plate 33 being deflected. After the push plate 33 pushes the drying plate 3 out of the storage box 4, the drying plate 3 is positioned on the inclined surface 35 of the placement table 2; when the second hinged door 21 is closed, the pulling force of the rope 34 disappears, the push plate 33 is pulled by the elastic force of the second spring 32 to move back, and when the push plate 33 is far away from the third hinged door 29, the third hinged door 29 is closed under the action of the third torsion spring 30, so that the drying plate 3 in the storage box 4 is reduced to be in contact with air; when the second spring 32 is in a natural state, one end of the push plate 33, which is close to the storage box 4, is inserted into the inner wall of the storage box 4 and does not contact the drying plate 3 in the storage box 4, and the drying plate 3 in the storage box 4 moves downwards until the drying plate 3 at the lowest end is aligned with the push plate 33.

As shown in fig. 2, the drying plate 3 on the inclined surface 35 slides onto the first hinge door 10 along the inclined surface 35, and the inclined surface 35 is arranged to slow down the time when the drying plate 3 reaches the first hinge door 10, and simultaneously to enable the drying plate 3 with the push plate 33 protruding to slide onto the first hinge door 10, thereby giving the first hinge door 10 a closing process, and a plurality of times, reducing the possibility of occurrence of the condition that the first hinge door 10 is not completely closed when the drying plate 3 reaches the first hinge door 10.

As shown in fig. 6, a fifth hinge door 44 is rotatably disposed on the outer side wall of the bottom end of the collecting box 20, a fifth torsion spring 45 is disposed on the second hinge door 21, the fifth hinge door 44 has a downward rotation tendency under the driving of the fifth torsion spring 45, a limiting block 49 is fixedly welded on one side wall of the fifth hinge door 44, the limiting block 49 is rectangular, and the limiting block 49 is disposed along the width of the fifth hinge door 44, a clamping block 47 is rotatably disposed on the side wall of the bottom end of the collecting box 20, and the clamping block 47 can be clamped to the limiting block 49, so that the fifth hinge door 44 can be fixed. When a period of time later, the staff needs to process the drying plate 3 used in the collection box 20, firstly, the staff places the garbage can for collecting the drying plate 3 below the collection box 20, then, when the staff rotates the clamping block 47 to enable the clamping block 47 to be far away from the limiting block 46, the fifth hinged door 44 is opened under the action of the fifth torsion spring 45, the drying plate 3 in the collection box 20 falls into the garbage can, then, the staff detects whether the residual drying plate 3 exists in the collection box 20, after no residue exists, the staff pulls the fifth hinged door 44 to rotate to be in a closed state, then, the staff rotates the clamping block 47 to be below the limiting block 46 and tightens the limiting block 46, and accordingly, the fifth hinged door 44 keeps in the closed state.

The implementation principle of the embodiment of the application is as follows: a placing table 2 is arranged in the box body 1, a drying plate 3 which absorbs water is placed on the placing table 2, and a storage box 4 for storing a new drying plate 3 is also arranged on the placing table 2; the box 1 is internally provided with a driving component 12 for driving the drying plate 3 to separate from the placing table 2, a collecting component 13 for collecting the used drying plate 3 and a replacing component 14 for placing a new drying plate 3 in the storage box 4 on the placing table 2, so that the drying plate 3 capable of absorbing moisture in air always exists in the box 1, the dryness of the air is increased, the possibility of damage of electrical equipment due to humidity is reduced, and economic loss is reduced.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
