[0002] Filing cabinets belong to the office furniture series. They are cabinets used to store archival materials. However, when filing cabinets are used in humid weather such as rainy days, their own moisture-proof effect is poor, so ventilation and dehumidification devices are required.

[0003] After searching the relevant patent: CN214759936U, a ventilation and dehumidification device for a filing cabinet is disclosed. The prior art can achieve simultaneous drying and dehumidification at the upper and lower ends by arranging a dehumidification device inside the filing cabinet body and arranging electric heating branches at the upper and lower ends of the interlayer rack. The use effect is significant and the damp files can be dehumidified faster.

[0004] However, the inventor discovered that the prior art had the following problems during implementation: the prior art adopted a method of extracting moisture from inside the filing cabinet, which resulted in a lower internal pressure after the moisture from inside the filing cabinet was extracted; however, the prior art can only be used in a humid environment, which resulted in external moisture still entering the filing cabinet through the ventilation holes, and it was impossible to completely isolate moisture from entering the filing cabinet. In response to the above problems, the inventor designed a new ventilation and dehumidification device for the filing cabinet. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a ventilation and dehumidification device for a filing cabinet which prevents external humid air from entering the filing cabinet through the ventilation holes, thereby ensuring the dryness inside the filing cabinet and ensuring the use effect of the dehumidification device.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A ventilation and dehumidification device for a filing cabinet comprises a cabinet body, wherein a vertical plate is fixedly connected between the upper and lower inner walls of the cabinet body, the vertical plate is located at the center of the cabinet body, and horizontal plates are fixedly connected between the opposite sides of the vertical plate and the inner wall of the cabinet body, the interiors of the vertical plate and the horizontal plate are hollow, and the two are internally connected, and the upper and lower side surfaces of the horizontal plate are provided with air outlet slots connected to the interior thereof, a heating shell is fixedly installed on the upper surface of the cabinet body, a plurality of heating rods are fixedly installed in the heating shell, an air supply pipe connected to the interior thereof is fixedly installed on the outer surface of the heating shell, and the other end of the air supply pipe passes through the vertical plate, and an air intake fan is fixedly connected to the upper surface of the heating shell, and the output port of the air intake fan passes through the heating shell.

[0008] The utility model is further configured as follows: the front side of the cabinet is rotatably connected to two cabinet doors, and the cabinet doors are provided with a plurality of ventilation holes.

[0009] The utility model is further configured as follows: a ventilation hood is fixedly connected to the top wall of the heating shell, and the ventilation hood is sleeved on the outer surface of the outlet of the suction fan.

[0010] The utility model is further configured as follows: a return frame is arranged inside the ventilation hood, the outer surface of the return frame is in contact with the inner wall of the ventilation hood, a filter is fixedly installed inside the return frame, and the filter is flush with the lower surface of the return frame.

[0011] The utility model is further configured as follows: one side of the return frame slides through the outer surface of the heating shell, and a pulling plate is fixedly connected to one side of the return frame located outside the heating shell.

[0012] The utility model is further configured as follows: a rotating shaft is rotatably connected between inner walls on two opposite sides of the ventilation cover, and an arc-shaped plate is fixedly sleeved on the outer surface of the rotating shaft.

[0015] The advantages of the utility model are:

[0016] Firstly, the utility model draws external air into the heating shell through the suction fan, the heating rod is started, and the air is heated. The heated air is transported to the vertical plate along the air duct, and finally blown into the filing cabinet through the air outlet slots on the horizontally placed plate. The moisture in the filing cabinet is discharged through the ventilation holes. Since the suction fan continuously transports the heated air into the filing cabinet, the pressure inside the filing cabinet is greater than the external pressure. Under the action of the pressure difference, the external humid air can be prevented from entering the filing cabinet through the ventilation holes, thereby ensuring the dryness of the filing cabinet and the use effect of the dehumidification device.

[0017] Secondly, the utility model is provided with a filter, which can filter out solid impurities in the air, thereby further preventing impurities in the air from entering the filing cabinet and adhering to the documents, ensuring the cleanliness of the documents placed in the filing cabinet. At the same time, an impact component is provided. When the suction fan stops running, the arc plate will impact the lower surface of the filter under the push of the supporting spring, so that the dust attached to the surface of the filter will shake, thereby minimizing the problem of dust adhering to the filter for a long time and adhering tightly, and reducing the difficulty of dust cleaning on the filter for the staff.

DETAILED DESCRIPTION

[0023] See also Figure 1-4 , the utility model provides the following technical solutions:

[0024] Specifically, it refers to a ventilation and dehumidification device for a filing cabinet, comprising a cabinet body 1 , the front of the cabinet body 1 is rotatably connected to two cabinet doors 2 for sealing the interior of the cabinet body 1 , and a plurality of ventilation holes 3 are opened on the cabinet doors 2 .

[0025] Specifically, a vertical plate 5 is fixedly connected between the upper and lower inner walls of the cabinet 1, and the vertical plate 5 is located at the center of the cabinet 1. Horizontal placement plates 6 are fixedly connected between the opposite sides of the vertical plate 5 and the inner walls of the cabinet 1. At the same time, the interiors of the vertical plate 5 and the horizontal placement plates 6 are hollow, and the two are internally connected. The upper and lower side surfaces of the horizontal placement plates 6 are provided with air outlet slots 7 connected to the interior thereof. A heating shell 4 is fixedly installed on the upper surface of the cabinet 1, and a plurality of heating rods 10 are fixedly installed in the heating shell 4. The heating rods 10 are existing known technologies and will not be described in detail here. An air supply pipe 8 connected to the interior thereof is fixedly installed on the outer surface of the heating shell 4, and the other end of the air supply pipe 8 passes through the vertical plate 5. An intake fan 9 is fixedly connected to the upper surface of the heating shell 4, and the output port of the intake fan 9 passes through the heating shell 4.

[0026] When in use, external air is drawn into the heating shell 4 through the suction fan 9, the heating rod 10 is started, and the air is heated. The heated air is transported to the vertical plate 5 along the air duct 8, and finally blown into the filing cabinet through the air outlet slot 7 on the horizontal placement plate 6. The moisture in the filing cabinet is discharged through the ventilation hole 3. Since the suction fan 9 continuously transports the heated air into the filing cabinet, the pressure inside the filing cabinet is greater than the external pressure. Under the action of the pressure difference, the external humid air can be prevented from entering the filing cabinet through the ventilation hole 3, thereby ensuring the dryness of the filing cabinet and the use effect of the dehumidification device.

[0027] Specifically, a ventilation hood 11 is fixedly connected to the top wall of the heating shell 4, and the ventilation hood 11 is sleeved on the outer surface of the output port of the suction fan 9. Therefore, when in use, the air delivered by the suction fan 9 is delivered to the heating shell 4 through the bottom of the ventilation hood 11.

[0028] Specifically, a circular frame 12 is provided in the ventilation hood 11, and the outer surface of the circular frame 12 is in contact with the inner wall of the ventilation hood 11. A filter 13 is fixedly installed in the circular frame 12, and the filter 13 is flush with the lower surface of the circular frame 12. When the suction fan 9 transports external air into the ventilation hood 11, the filter 13 can filter the transported air to filter out solid impurities in the air, thereby further preventing impurities in the air from entering the filing cabinet and adhering to the documents, thereby ensuring the cleanliness of the documents placed in the filing cabinet.

[0029] Specifically, one side of the return frame 12 slides through the outer surface of the heating shell 4, and a pulling plate 14 is fixedly connected to one side of the return frame 12 outside the heating shell 4, so the return frame 12 can be pulled out through the pulling plate 14, so as to facilitate cleaning of impurities on the filter 13.

[0030] Specifically, a rotating shaft 15 is rotatably connected between the inner walls of the two opposite sides of the ventilation hood 11, and an arc-shaped plate 16 is fixedly sleeved on the outer surface of the rotating shaft 15. The arc-shaped plate 16 is arranged on the lower side of the filter screen 13, and the top of the arc-shaped plate 16 contacts the lower surface of the filter screen 13. A supporting spring 17 is fixedly connected between the lower surface of the arc-shaped plate 16 and the inner wall of the ventilation hood 11. When the supporting spring 17 is not affected by pressure, the supporting spring 17 will form a thrust on the arc-shaped plate 16, so that the top of the arc-shaped plate 16 contacts the lower surface of the filter screen 13. When the air blower 9 delivers air into the ventilation hood 11, the airflow will form a thrust on the arc plate 16, causing the arc plate 16 to rotate downward, and at the same time the support spring 17 is stressed and contracts. When the air intake fan 9 stops running, the arc plate 16 will hit the lower surface of the filter 13 under the push of the support spring 17, so that the dust attached to the surface of the filter 13 will shake, which minimizes the problem of dust adhering to the filter 13 for a long time and adhering tightly, and reduces the difficulty of cleaning the dust on the filter 13 for the staff.

[0031] The working principle of the ventilation and dehumidification device of the filing cabinet provided by the utility model is as follows: external air is drawn into the heating shell 4 through the suction fan 9, the heating rod 10 is started, and the air is heated, and the heated air is transported to the vertical plate 5 along the air supply pipe 8, and finally blown into the filing cabinet through the air outlet slot 7 on the horizontal placement plate 6, and the moisture in the filing cabinet is discharged through the ventilation hole 3.
