[0038] Compared with the prior art, at least one of the above one or more technical solutions in the moisture-proof file rack for file management provided by the embodiment of the present utility model has the following technical effects:

[0039] Referring to Figure 1 and Figure 2 , during use, the hair dryer 120 and the exhaust fan 130 operate simultaneously. The hair dryer 120 enters the outside air from the air inlet hole 101 into the drying cavity 110 on the left. Then, when the air passes through the drying device 140 and enters the first file placement cavity 150 through a plurality of air through holes, the drying device 140 adsorbs the moisture in the air, so that the air flowing into the first file placement cavity 150 is dry air. And the exhaust fan 130 outputs the air in the drying cavity 110 on the right to the outside through the air outlet hole 102. The hair dryer 120 and the exhaust fan 130 form an air convection, so that the air flowing into the first file placement cavity 150 passes through a plurality of air through holes 190 and sequentially passes through a plurality of first file placement cavities 150, the stacking cavity 180, a plurality of second file placement cavities 170, and the drying cavity 110 on the right and is output from the air outlet hole 102, performing circulating ventilation on the files 250 placed in the first file placement cavity 150, the stacking cavity 180, and a plurality of second file placement cavities 170, avoiding the files 250 from getting damp, and protecting the files 250.

[0040] In another embodiment of the present utility model, referring to Figure 1 , Figure 3 and Figure 4, on the outer side of each lower positioning groove 162, there is a uniform limiting mechanism 210, and the limiting mechanism 210 includes a spring 211 and a limiting block 212. On the outer side of each lower positioning groove 162 of the cabinet main body 100, a mounting groove 103 is recessed, and a through groove 104 is opened on the groove wall of the mounting groove 103. The limiting block 212 is slidably installed in the mounting groove 103, the spring 211 is installed in the mounting groove 103, and the two ends of the spring 211 are respectively connected to the bottom of the limiting block 212 and the bottom of the mounting groove 103. A limiting end 213 is provided at the top of the limiting block 212, and a pressing portion 214 is provided on the side wall of the limiting block 212. The pressing portion 214 passes through the through groove 104 and extends outwards. The spring 211 has an elastic force to drive the limiting end 213 to extend out of the mounting groove 103, and the limiting end 213 extending out of the mounting groove 103 is used to limit the file 250 in the corresponding upper positioning groove 161 and lower positioning groove 162. Specifically, when placing the file 250, the limiting end 213 retracts into the mounting groove 103 and compresses the spring 211 to make way for the file 250, so that the file 250 jumps over the limiting end 213 and is placed in the corresponding upper positioning groove 161 and lower positioning groove 162. Then the spring 211 elastically resets and pushes the limiting end 213 to move up and reset along the mounting groove 103. By blocking the outer side of the file 250 with the limiting end 213, the file 250 is stably placed in the corresponding upper positioning groove 161 and lower positioning groove 162. Even if the cabinet main body 100 of the moisture-proof file rack for file management is placed on an uneven ground, the phenomenon that the file 250 slides out of the positioning groove and falls will not occur, and the structure is reliable. When it is necessary to take out the file 250, the user presses the pressing portion 214 to drive the limiting end 213 to move down along the mounting groove 103, so that the limiting end 213 retracts into the mounting groove 103, and the file 250 can be taken out from the corresponding upper positioning groove 161 and lower positioning groove 162, and the operation is simple.

[0041] Further, referring to Figure 1 , Figure 3 and Figure 4 , on the outer side of the limiting end 213, there is an inclined guiding surface 213a. During the process of the user putting the file 250 into the corresponding upper positioning groove 161 and lower positioning groove 162, the file 250 pushes the limiting end 213 to move down along the mounting groove 103 through the inclined guiding surface 213a, so that the limiting end 213 retracts into the mounting groove 103 and compresses the spring 211, thereby enabling the file 250 to jump over the limiting end 213 and be placed in the corresponding upper positioning groove 161 and lower positioning groove 162. Then the spring 211 elastically resets and pushes the limiting end 213 to move up and reset along the mounting groove 103, so that the limiting end 213 restricts the file 250 in the corresponding upper positioning groove 161 and lower positioning groove 162, and the operation is convenient.

[0042] In another embodiment of the present invention, referring to Figure 1 and Figure 2The drying device 140 is a water-absorbing carbon box, which has strong water absorption and can alleviate the humidity factor in the air. The water-absorbing carbon box is a mature existing technology. The water-absorbing carbon box can be detachably installed at the bottom of the drying chamber 110, and the water-absorbing carbon box absorbs the moisture in the air passing through it, so that the air passing through the water-absorbing carbon box from the air through hole 190 into the first file placement chamber 150, the stacking chamber 180 and the second file placement chamber 170 is dry air.

[0043] Further, refer to Figure 1 and Figure 2 The left and right side walls of the bottom of the drying chamber 110 are each provided with a limit plate 220, and a slide groove is formed between the limit plate 220 and the bottom wall of the drying chamber 110. The left and right sides of the water-absorbing carbon box are detachably installed at the bottom of the drying chamber 110 along the two slide grooves. After the water-absorbing carbon box has been used for a certain period of time, the user can remove the water-absorbing carbon box from the two slide grooves and replace the water-absorbing carbon box to ensure the moisture-proof performance of the file rack.

[0044] Further, refer to Figure 1 and Figure 2 A handle 141 is provided on the outer side of the water absorbing carbon box, and the handle 141 is convenient for the user to remove the water absorbing carbon box from the two slide grooves, which is convenient for operation.

[0045] In another embodiment of the present invention, referring to Figure 1 and Figure 2 A slot 105 is provided above the two drying chambers 110 at the front end of the cabinet body 100. The two slots 105 extend to the air inlet 101 and the air outlet 102 respectively. One or more layers of filter nets 230 can be removably inserted in the two slots 105, and the two filter nets 230 cover the air inlet 101 and the air outlet 102 respectively. The two filter nets 230 are used to filter dust or insects in the air passing through the air inlet 101 and the air outlet 102, and protect the hair dryer 120 and the exhaust fan 130, thereby increasing the service life of the hair dryer 120 and the exhaust fan 130. After using for a certain period of time, the user can pull out the filter net 230 from the slot 105 to clean or maintain the filter net 230, which is convenient to use.

[0046] Further, refer to Figure 1 and Figure 2 The slot 105 is provided with a removal slot 106 in the slot opening.
