[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 This utility model provides a technical solution: a ventilation-type moisture-proof display cabinet for valuable goods, including an upper cabinet body 1, a support plate 2, a display platform 3, a first sealing strip 4, a second sealing strip 5, an exhaust pipe 6, a connecting hole 7, a lower cabinet body 8, a drying cylinder 9, an air inlet pipe 10, a negative pressure fan 11, a connecting pipe 12, a filter plate 13, a connecting block 14, and a receiving plate 15.

[0029] The upper cabinet 1 is a display cabinet with a glass surface. The rear surface of the upper cabinet 1 is open, and a support plate 2 slides through its rear edge. The support plate 2 has a trapezoidal cross-section, and a stepped display stand 3 is fixedly installed on its bottom surface. A latch locks the upper cabinet 1 and the support plate 2. An L-shaped protrusion is located at the top of the support plate 2, and a first sealing strip 4 is fixedly installed on the lower surface of this protrusion. The lower part of the first sealing strip 4 is tightly fitted with a second sealing strip 5, which is also fixedly installed on the upper cabinet 1. On the upper surface, the two sides of the support plate 2 are provided with another set of No. 1 sealing strips 4. The No. 1 sealing strips 4 are tightly attached to the rear surface of the upper cabinet 1. The upper cabinet 1 is provided with an air outlet structure. The air outlet structure realizes the outward flow of air inside the upper cabinet 1 through the air outlet pipe 6, ensuring the air flow inside the upper cabinet 1. The air outlet structure includes the air outlet pipe 6, which is installed through the side surface of the upper cabinet 1. The air outlet pipe 6 is provided with a one-way valve inside. The flow direction of the one-way valve inside the air outlet pipe 6 is from the upper cabinet 1 to the outside. Two sets of air outlet pipes 6 are symmetrically arranged on the two sides of the upper cabinet 1.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, when using this device to display goods, use the key to unlock the latch between the upper cabinet 1 and the support plate 2, pull the support plate 2 out from the rear surface of the upper cabinet 1, and place the goods on the display stand 3 on the surface of the support plate 2. Push the support plate 2 in the opposite direction to reinsert it into the upper cabinet 1. At this time, the first sealing strip 4 at the top of the support plate 2 should be tightly fitted with the second sealing strip 5 on the upper surface of the upper cabinet 1, and the first sealing strips 4 on both sides of the support plate 2 should also be tightly fitted with the rear surface of the upper cabinet 1 to ensure the airtightness of the display cabinet and prevent external moisture and dust from entering. Use the key to relock the upper cabinet 1 and the support plate 2. The air inside the upper cabinet 1 flows to the outside along the one-way air outlet pipe 6 to avoid the accumulation of humid air inside the upper cabinet 1, which would affect the quality of the goods.

[0031] Below the upper cabinet 1 is a lower cabinet 8. The lower cabinet 8 has an air intake structure inside. The air intake structure allows outside air to flow into the upper cabinet 1 through the air intake pipe 10. The air intake structure includes a drying cylinder 9, which is fixedly installed on the bottom surface of the lower cabinet 8. The drying cylinder 9 is hollow inside. Air intake pipes 10 are respectively installed through the two sides of the drying cylinder 9. A negative pressure fan 11 is installed on the inner wall of the air intake pipe 10. The upper end of the drying cylinder 9 is connected to the connecting pipe 12 through the pipe. The upper end of the connecting pipe 12 penetrates the surface of the lower cabinet 8 and the upper cabinet 1 and is inserted into the interior of the upper cabinet 1. The upper part of the connecting pipe 12 is aligned with the connecting hole 7. The connecting hole 7 is installed through the bottom surface of the support plate 2.

[0032] like Figure 4 and Figure 5 As shown, when the device displays the goods, the negative pressure fan 11 in the air inlet pipe 10 is activated. The negative pressure fan 11 draws outside air into the air inlet pipe 10. The air enters the drying cylinder 9 through the air inlet pipe 10 and continues to enter the connecting pipe 12. Since the connecting pipe 12 is aligned with the connecting hole 7, the air will eventually pass through the connecting hole 7 and enter the interior of the upper cabinet 1. Together with the air outlet pipe 6, airflow is formed inside the upper cabinet 1, ensuring air circulation inside the upper cabinet 1 and increasing the moisture-proof effect of the upper cabinet 1.

[0033] Two filter plates 13 are fixedly installed on the inner wall of the air inlet duct 10. The two filter plates 13 are arranged in parallel, and the filter hole size on the surface of the two filter plates 13 is arranged in descending order. The drying cylinder 9 is a cylindrical structure. A semi-circular notch is provided on the front surface of the drying cylinder 9. A connecting block 14 is installed in the notch on the surface of the drying cylinder 9. The connecting block 14 is a circular base plate of a vertically connected semi-circular vertical plate. The vertical plate of the connecting block 14 is bolted to the surface of the drying cylinder 9. A circular ventilation hole is provided on the surface of the circular base plate of the connecting block 14. A receiving plate 15 is fixedly installed on the upper surface of the connecting block 14. The receiving plate 15 is a structure of multiple concentric rings. A circular ventilation hole is provided through the surface of the receiving plate 15. The connecting block 14 and the receiving plate 15 constitute the receiving structure of the desiccant.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, when air enters along the air inlet pipe 10, it first comes into contact with two filter plates 13 inside the air inlet pipe 10. Under the interception of the filter plates 13 with decreasing filter hole size, dust and impurities are blocked, preventing dust from entering the device. The filtered air flows into the drying cylinder 9. During the movement inside the drying cylinder 9, the air comes into contact with the desiccant containing structure composed of the connecting block 14 and the receiving plate 15. Under the adsorption of the desiccant, the moisture in the air is adsorbed, preventing humid air from entering the device and affecting the goods. When the desiccant of the device needs to be replaced, loosen the connecting bolts on the surface of the connecting block 14 and the drying cylinder 9, pull out the connecting block 14 and the receiving plate 15, replace with new desiccant, and reinsert the connecting block 14 and the receiving plate 15 into the drying cylinder 9 to complete the replacement of the desiccant.

[0035] Working principle: When using this exhaust-type moisture-proof display cabinet for valuable goods, the sliding support plate 2 supports the goods, and the latch locks the support plate 2 and the upper cabinet 1. During use, the negative pressure fan 11 is started, which draws in outside air. After being filtered by the filter plate 13 in the air inlet pipe 10, the air enters the drying cylinder 9. The moisture in the air inside the drying cylinder 9 is absorbed by the desiccant. Finally, the treated air enters the interior of the upper cabinet 1 along the connecting pipe 12. Together with the air outlet pipe 6, airflow is formed inside the upper cabinet 1, ensuring air circulation and dryness, thereby ensuring the quality of the goods and increasing the overall practicality.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
