[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] Example 1

[0037] like Figure 1-6As shown, this embodiment discloses a dehumidifying filing cabinet capable of extending the storage time of paper documents, comprising a cabinet body 1. The cabinet door on the cabinet body 1 cannot completely seal the cavity 11, so that the hot air flow in the cavity 11 can slowly flow out. A trapezoidal partition 4 for support is provided at the lower part of the inner cavity of the cabinet body 1. The trapezoidal partition 4 divides the inner cavity of the cabinet body 1 into two parts, cavity 11 and cavity 2 12. Cavity 11 is used to store paper documents, and cavity 2 12 is used to guide air into cavity 11 along a predetermined channel to prevent hot air from directly entering cavity 11 and blowing the paper documents away. Horizontal slots 16 are provided on the upper parts of the left and right inner walls of cavity 11, which pass through the rear end of the cabinet body 1, so that a trapezoidal bracket 2 can be added at any time to classify and store paper documents, while compressing the space occupied by a single file, thereby improving space utilization. The two horizontal slots The bottom wall of each of the cabinets 16 is provided with two limiting grooves 17 that penetrate the left and right inner walls of the cavity 11, so that the trapezoidal bracket 2 can only move up and down in the cavity 11, and the left and right side walls of the cabinet 1 are provided with circulation grooves 13. The circulation grooves 13 are close to the side wall of the inner cavity of the cabinet 1 and are evenly provided with multiple circulation holes 14 that penetrate the two limiting grooves 17 respectively. There are multiple trapezoidal brackets 2 on the left and right inner walls of the cavity 11, and the multiple trapezoidal brackets 2 on both sides are staggered with each other. The inclined part of the trapezoidal bracket 2 is used to block the rising hot air flow and intercept the water vapor therein, forcing it to condense into water droplets for collection or treatment, thereby preventing the water vapor from flowing around and being absorbed by paper documents, thereby reducing the storage time of paper documents. The multiple trapezoidal brackets 2 on the same side are provided with two limiting blocks 5 that are slidably connected to the two limiting grooves 17 at one end close to the limiting groove 17;

[0038] For details, please refer to Figure 2 , an air intake fan 3 communicating with the second cavity 12 is provided at the lower right end of the cabinet 1, a part of the air intake fan 3 close to the cabinet 1 passes through the side wall of the cabinet 1 and extends into the second cavity 12, and a ventilation protective cover 31 is provided on the middle of the right inner wall of the second cavity 12, which is located outside the air intake fan 3. An electric heating wire is provided on the inner side of the ventilation protective cover 31 for heating the air entering the second cavity 12. The left and right inner walls of the second cavity 12 are respectively provided with connecting grooves 15 communicating with the two circulation grooves 13. The air drawn into the second cavity 12 by the air intake fan 3 is heated by the electric heating wire inside the ventilation protective cover 31 to become a hot air flow when passing through the ventilation protective cover 31, and then the hot air flow floats up through the connecting groove 15 and enters the circulation groove 13;

[0039] As can be seen from the above, the trapezoidal bracket 2 is first placed horizontally into the cavity 11 through the limiting block 15 and the horizontal groove 16, and then the limiting block 15 is used to slide in the limiting groove 17 to make the trapezoidal bracket 2 slide down to the bottom of the cavity 11, so as to make room for the paper documents stored subsequently. After that, the sorted paper documents are placed on the upper end of the trapezoidal bracket 2, and the above steps are repeated. A new trapezoidal bracket 2 is placed and the paper documents are pressed to prevent them from being blown away by the air flow blown out from the circulation hole 14. Then, the air intake fan 3 is started to introduce the outside air into the cavity 2 12. When passing through the ventilation protective cover 31, the air is heated by the electric heating wire therein to become hot air flow, and finally blown toward the paper documents through the connecting groove 15, the circulation groove 13 and the circulation hole 14 to remove moisture in the paper documents, thereby extending the storage time of the paper documents.

[0040] In addition, a triangular plate 22 is provided at a portion of the upper end of the trapezoidal bracket 2 away from the circulation hole 14 to prevent water droplets condensed on the inclined portion of the trapezoidal bracket 2 from sliding directly along the inclined surface to the vicinity of the documents. The horizontal width of the triangular plate 22 is equal to the horizontal width of the inclined portion of the trapezoidal bracket 2, to avoid affecting the downward pressure of the trapezoidal bracket 2, while being able to accept the sliding water droplets to the greatest extent. The inner cavity of the triangular plate 22 is filled with a desiccant, and a plurality of air holes 23 are evenly arranged on the side with a higher horizontal height of the upper end of the triangular plate 22, which penetrates its inner cavity. Even in the subsequent storage process of the documents, the desiccant and the inclined surface on the triangular plate 22 can reduce the contact between water vapor and even water droplets and the paper documents, thereby extending the storage time of the paper documents.

[0041] For details, please refer to Figure 3-4 , the upper front and rear ends of the trapezoidal bracket 2 are both provided with a slide groove 24 that is not connected to the mounting groove. The interior of the two slide grooves 24 is provided with an L-shaped limit plate 6 for forcing the paper to align. Nowadays, A4 paper is commonly used for printing paper documents. Therefore, the distance between the ends of the two L-shaped limit plates 6 that are close to each other is equal to the length of the A4 paper, so as to facilitate the arrangement of scattered documents. Two springs 25 are provided between the lower end of the L-shaped limit plate 6 and the lower end of the slide groove 24 to further compress the space occupied by a single document. The left end of the vertical part of the L-shaped limit plate 6 is evenly provided with a plurality of air vents 61 that pass through its right end to facilitate the escape of air.

[0042] For details, please refer to Figure 4-5The upper end of the trapezoidal bracket 2 is provided with a groove 21. The width of the A4 paper is slightly larger than the distance between the end of the vertical part of the L-shaped limit plate 6 close to its horizontal part and the side of the groove 21 close to the L-shaped limit plate 6, so that the subsequent L-shaped rubber pad 915 can lift the A4 paper, expand the gap between the documents and papers, and allow air to pass through it to take away the moisture of the paper. The lower end of the trapezoidal bracket 2 is provided with a mounting groove, and the interior of the mounting groove is provided with a sponge pad 74 and two sponge pads 74 located respectively. 4 L-shaped movable plates 72 on the front and rear sides, and the two L-shaped movable plates 72 are symmetrically distributed. The lower end of the L-shaped movable plate 72 is provided with a second slide groove 721. The interior of the second slide groove 721 is provided with an L-shaped limiting plate 7. Two springs 722 are provided between the upper end of the second L-shaped limiting plate 7 and the top wall of the second slide groove 721 to further compress the space occupied by a single document. The left end of the vertical portion of the second L-shaped limiting plate 7 is evenly provided with a plurality of air vents 71 running through the right end thereof to facilitate airflow.

[0043] The lock hole 731 of locking plate 71 is provided with the lock hole 732 of locking plate 71, and the lock hole 733 of locking plate 71 is provided with the lock hole 734 of locking plate 71.

[0044] For further information, see Figure 6 In the initial state, the inner side walls of the vertical and horizontal parts of the L-shaped limiting plate 1 6 are respectively located in the same plane as the inner side walls of the vertical and horizontal parts of the L-shaped limiting plate 2 7. Even if the number of sheets of a single document is too large and exceeds the height of the L-shaped limiting plate 1 6, the L-shaped limiting plate 2 7 can still be used to organize and protect them.

[0045] As can be seen from the above, when the height of the document paper is less than the height of the L-shaped limit plate 1 6, the document can be placed normally. Then, in the process of continuously stacking the trapezoidal bracket 2, the spring 1 25 and the spring 2 722 will be compressed, so that the L-shaped limit plate 1 6 and the L-shaped limit plate 2 7 will be retracted into the slide groove 1 24 and the slide groove 2 721 respectively, so that the trapezoidal bracket 2 presses the document, reducing wrinkles on the surface of the document and improving the storage quality.

[0046] When the height of the document paper is greater than the height of the L-shaped limiting plate 1 6, the documents are first placed neatly, and then when placing the trapezoidal bracket 2, the two L-shaped limiting plates 2 7 are pressed against the corners of the documents until the L-shaped limiting plates 1 6 and 2 7 are pressed against each other, and the above steps are repeated subsequently;

[0047] When the height of the document paper is less than the height of the L-shaped limit plate 1 6 and the length is less than the distance between the ends of the two L-shaped limit plates 1 6, the knob 733 is turned to control the L-shaped movable plates 72 to move closer to each other, so that the L-shaped limit plate 2 7 moves away from the top of the L-shaped limit plate 1 6, and then the trapezoidal bracket 2 is lowered until the L-shaped limit plate 2 7 touches the bottom first, so that the two L-shaped limit plates 2 7 surround the outside of the document, and then the knob 733 is continued to be turned to control the two L-shaped limit plates 2 7 to move toward the document, so as to align the edges and corners of the document, and then the document is pressed in place and kept stationary under the continuous stacking of the trapezoidal bracket 2;

[0048] If there are too many small documents and the height is greater than the height of the L-shaped limit plate 6, there is no need to use this device to avoid the documents being blown away in the subsequent air blowing and dehumidification process.

[0049] Example 2

[0050] This embodiment further improves the dehumidification of the file cabinet based on the first embodiment. Figure 7-10 As shown, the rear ends of the two limit blocks 5 located on the same side are each provided with an air inlet slot 51 extending into the interior of the trapezoidal bracket 2, and the inner surfaces of the two air inlet slots 51 are each provided with a mounting plate 53. The middle portion of the end of the two mounting plates 53 close to the circulation hole 14 is provided with a rotating rod 54, and the end of the two rotating rods 54 close to the circulation hole 14 is provided with a rotating fan 55. The ends of the two mounting plates 53 away from the circulation hole 14 pass through the mounting plate 53 and are provided with a rotating rod 54.

[0051] The heated hot air flows through the connecting groove 15, the circulation groove 13 and the plurality of circulation holes 14 into the cavity 11. When a portion of the air flows out of the circulation hole 14, it directly enters the limit block 5 slidably connected to the limit groove 17 through the air inlet groove 51. The air flow then drives the rotating fan 55 to rotate, and drives the subsequent components to work through the rotating rod 54.

[0052] For details, please refer to Figure 7-8, a side wall of the two air inlet slots 51 away from the circulation hole 14 is provided with an empty slot 57, and the sides of the outer surfaces of the two bevel gears 1 56 that are close to each other are meshed with the bevel gear 2 8 located inside the empty slot 57, and the ends of the two bevel gears 2 8 that are close to each other are jointly provided with a rotating rod 1 81 that is rotatably connected to the inside of the trapezoidal bracket 2, so that the two bevel gears 2 8 can rotate simultaneously, and the outer surfaces of the rotating rod 1 81 and the rotating rod 2 83 are jointly provided with two transmission belts 82 that are respectively located in the two empty slots 57, that is, the rotating fan 55 drives the bevel gear 1 56 to rotate through the rotating rod 54, and then the bevel gear 1 56 drives the meshed bevel gear 2 8 to rotate, and finally the bevel gear 2 8 drives the rotating rod 2 83 to rotate through the rotating rod 1 81 and the transmission belt 82;

[0053] Specifically, the diameter of the air inlet slot 51 is larger than the diameter of the circulation hole 14, and the distance between the bottom of the air inlet slot 51 and the lower end of the limit block 1 5 is equal to the distance between two adjacent circulation holes 14 in the same vertical plane. In other words, the air inlet channel is enlarged, making it easier for the rotating fan 55 to blow. At the same time, the probability of part of the airflow entering the gap between the two trapezoidal supports 2 where paper documents are placed is increased, making it easier for the documents to be directly blown by the hot air flow, thereby reducing the moisture content in the paper documents.

[0054] Specifically, an annular groove 52 is formed at one end of the stopper 5 near the circulation hole 14 and is located outside the air inlet groove 51. A dustproof net 58 is provided inside the annular groove 52 to prevent dust from being blown directly onto the documents and deposited on the documents. Such deposits will gradually increase and form dust and dirt. Then, under the action of water, the dust and dirt will become firmly bonded to the paper, causing stains and wear on the paper, increasing the risk of mold on the paper, and accelerating the aging of the paper, thereby reducing the storage time of paper documents.

[0055] For details, please refer to Figure 7 A movable groove penetrating the lower end of the trapezoidal bracket 2 is provided in the middle of the bottom wall of the empty slot 57. The length of the movable groove is equal to the distance that the rectangular frame 9 moves left and right. A cam 84 is provided on the side of the two empty slots 57 away from the flow hole 14. The two cams 84 are provided with a rotating rod 83 rotatably connected to the inside of the trapezoidal bracket 2 at one end thereof. The cams 84 rotate along with the transmission belt 82. A rectangular frame 9 is provided on the outside of the two cams 84. When the cams 84 rotate, the rectangular frame 9 is pushed outward, so that the rectangular frame 9 moves along a rectangular track.

[0056] For details, please refer to Figure 9, a limit block 2 96 is provided at the upper end of the rectangular frame 9, and a slide groove 4 961 is provided at the left end of the limit block 2 96 and passes through its right end. A T-shaped groove 571 is provided in the upper middle part of the inner wall of the empty slot 57 away from the limit block 1 5, and a disc 572 is provided inside the vertical part of the T-shaped groove 571. A slide rod 573 is provided in the middle part of the end of the disc 572 close to the rectangular frame 9, which is slidably connected to the horizontal part of the disc 572 and the inner surface of the slide groove 4 961. When the rectangular frame 9 moves in the horizontal direction, it drives the limit block 2 96 to slide on the outer surface of the slide rod 573, and when the rectangular frame 9 moves in the vertical direction, the slide rod 573 pulls the disc 572 to move upward in the T-shaped groove 571;

[0057] For further information, see Figure 10 The lifting mechanism 91 is fixedly connected to the lower end of the rectangular frame 9, and a slide 912 is provided on the outer surface of the vertical plate 911. A slide 912 is provided on the upper end of the slide 912 so that the lifting mechanism 91 can be retracted to avoid affecting the pressing and fixing of the trapezoidal bracket 2 on the document. The lower end of the vertical plate 911 extends to the inside of the slide 913 and is provided with two springs 914 together with the bottom wall of the slide 913. An L-shaped rubber pad 915 is provided at one end of the slide 912 close to the L-shaped limiting plate 27 to minimize the damage caused to the L-shaped rubber pad 915 when it moves up to lift the paper.

[0058] In addition, when the lifting mechanism 91 moves to the maximum distance in the direction of the document, the inclined part of the L-shaped rubber pad 915 away from the slide 912 enters the groove 21, making it easier for the L-shaped rubber pad 915 to lift the paper, allowing hot air to enter the gaps between the paper and take away the moisture in the paper.

[0059] Therefore, the specific implementation of this embodiment is as follows:

[0060] After the hot air flow enters the air inlet slot 51 through the circulation hole 14, it blows the rotating fan 55 to rotate, driving the rotating rod 54 and the bevel gear 1 56 to rotate, and then the bevel gear 1 56 drives the meshed bevel gear 2 8 to rotate, and finally the bevel gear 2 8 drives the cam 84 to rotate through the rotating rod 1 81, the transmission belt 82 and the rotating rod 2 83, pushing the rectangular frame 9 outward to move along a rectangular trajectory. When the lifting mechanism 91 moves to the maximum distance in the direction of the document, the inclined part of the side of the L-shaped rubber pad 915 away from the slide 912 enters the groove 21, and then in the upward movement process, the paper is pushed upward to expand the gap between the papers for the air flow blown out from the circulation hole 14 and the moving slot to pass through, thereby taking away the moisture on the paper inside the document, thereby reducing the moisture content of the paper, and thus extending the storage time of the paper document.
