Description

Technical Field

[0001] The utility model belongs to the technical field of moisture-proofing, and in particular relates to a moisture-proofing structure. Background Art

[0002] In many applications that require moisture protection, keeping the internal environment dry is a key factor in ensuring the normal preservation of exhibits and extending their display life. For example, in museums, exhibition halls, jewelry stores and other places, humid air in the display cabinet may cause the exhibits to become damp, deteriorate or be damaged. Therefore, how to effectively control and manage the humidity in the display cabinet has become an important technical issue.

[0003] In the prior art, common measures to prevent moisture in display cabinets include using sealed display cabinets, moisture-proof agents, dehumidifiers, etc. Although these methods can mitigate the impact of humid air on displayed items to a certain extent, they also have many shortcomings. During long-term use of sealed display cabinets, the sealing performance may decrease, resulting in air leakage. Moisture-proof agents need to be replaced frequently after their moisture absorption capacity reaches saturation, increasing maintenance costs. Although dehumidifiers are effective, they consume a lot of energy and require regular cleaning and maintenance. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a moisture-proof structure, which can effectively control the humidity inside the display cabinet and keep the internal environment dry by cleverly designing the air flow path and using a desiccant.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A moisture-proof structure comprises a cabinet body, a cabinet top plate is inserted on the top of the cabinet body, a storage bin is opened on the back of the cabinet body, and an air supply component is arranged on the bottom of the storage bin;

[0007] The air supply assembly includes a fan, and a filter is connected to one side of the fan;

[0008] An input hole is provided inside one side of the cabinet;

[0009] A positioning hole corresponding to the input hole is formed through the other side of the cabinet, and an exhaust assembly is inserted into each positioning hole;

[0010] The exhaust assembly comprises an exhaust pipe, one end of which is fixedly connected to a mesh plate, the inner side of which is fixedly connected to a guide column, a piston disc and a spring are sleeved on the guide column, and one end of the guide column is connected to a blocking cover.

[0011] Furthermore, an air inlet duct is provided on one side of the fan, and an air exhaust duct is provided on the other side of the fan;

[0012] The filter element is connected to the air inlet pipe;

[0013] One end of the filter element is provided with a receiving groove, a filter element is placed in the receiving groove, and the other end of the filter element is evenly penetrated with filter holes.

[0014] Furthermore, an air inlet hole is formed through one end of the bottom of the storage bin, the filter is inserted into the air inlet hole, and a retaining ring is fixedly connected to the outer side of one end of the filter.

[0015] Furthermore, the exhaust pipe is inserted into the positioning hole, and an inner ring is fixedly connected to the inner side of one end of the exhaust pipe;

[0016] A guide hole is formed through the center of the side surface of the piston disc, and a guide column passes through the guide hole.

[0017] Furthermore, the top of the cabinet is symmetrically provided with plugging holes, and both ends of the cabinet top plate are fixedly connected with plugging columns corresponding to the plugging holes.

[0018] Furthermore, partition plates are arranged at equal intervals on the inner side of the cabinet.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The moisture-proof structure of the utility model can effectively control the humidity inside the display cabinet and keep the internal environment dry through the air flow path and the use of desiccant. First, the outside air is driven by the fan to enter the storage bin of the display cabinet through the filter element provided with desiccant, thereby ensuring that the air entering the storage bin is dry. The dry air enters different layered spaces through the input hole and is discharged outside the display cabinet through the exhaust assembly. During the air flow process, the humid air in the display cabinet can be taken away, so that the interior of the display cabinet is always kept dry.

[0021] The filter element design of the utility model ensures that the air entering the storage bin is effectively dried by filling the receiving groove with desiccant; the combination of the fan and the filter element ensures that the air reaches the dry standard before entering the showcase, effectively reducing the source of moisture inside the showcase. At the same time, the filter element inside the filter element further removes impurities in the air, ensuring that the air entering the showcase is not only dry but also clean, providing a good display environment.

[0022] The design of the exhaust assembly is also very clever. Through the combination of the exhaust pipe, mesh plate, guide column, piston disc and spring, the air can be discharged smoothly after entering the showcase. When the air passes through the exhaust assembly, the piston disc moves along the axial direction of the guide column under the push of air pressure, and the air can enter the exhaust pipe and be discharged outside the showcase through the exhaust pipe; when the fan stops working, the elastic force of the spring makes the piston disc fit on the mesh plate, preventing the air outside the showcase from entering the showcase through the exhaust pipe, thereby effectively preventing the outside humid air from entering the showcase.

[0023] Through such a design, the utility model overcomes the shortcomings of the prior art and provides a more efficient and reliable display cabinet moisture-proof solution. The improvement of sealing performance, the effective use of desiccant, and the optimization of air flow paths keep the internal environment of the display cabinet dry at all times, protecting the integrity and quality of the displayed items. The overall design is simple and efficient, easy to maintain and operate, reducing the cost of use and improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] See also Figure 2 , Figure 4 and Figure 5 An air inlet pipe 311 is provided on one side of the fan 31 for introducing outside air, and an air exhaust pipe 312 is provided on the other side of the fan 31 for exhausting air into the cabinet; the filter element 33 is connected to the air inlet pipe 311 to ensure that the air entering the fan 31 is filtered and dried; a receiving groove 333 is provided at one end of the filter element 33, and a filter element is placed in the receiving groove 333. The filter element is used to further filter impurities in the air, and filter holes 331 are evenly penetrated at the other end of the filter element 33.
