Description

Technical Field

[0001] This application belongs to the field of desiccant application technology, and in particular relates to an electrothermal dehydration desiccant box. Background Technology

[0002] Desiccants are widely used in all aspects of human production and life. Color-changing granular desiccants, due to their ease of use and reusability, have become an essential condition for the storage environment of important humidity-sensitive items such as precision optical instruments. Currently, the common method of using desiccants is to put them in a breathable bag and place the bag in a relatively sealed space such as an instrument case. In this case, the desiccant gradually absorbs moisture, changes color, and eventually loses its dehumidifying effect. During the moisture absorption process, a low humidity is created in the sealed space, protecting the instruments and other items within. For desiccants that have completely changed color and lost their dehumidifying effect, dehydration can be achieved through heating, but this method requires specialized heating equipment and is not suitable for special environments such as laboratories, warehouses, and the field. Regularly replacing desiccants not only increases costs but also complicates operation and management. Due to these two factors, important items such as precision optical instruments are at risk of long-term exposure to humid environments, which can easily cause mold growth on sensitive components, leading to performance degradation or even scrapping. Summary of the Invention

[0003] This application addresses the practical needs of desiccant applications by proposing an electrically heated dehydrating desiccant box that can easily restore drying efficiency by heating and dehydration after the desiccant absorbs moisture, changes color, and becomes ineffective.

[0004] This application is achieved through the following technical measures: It includes a desiccant box body, one end of which is completely open, and the other end is a sieve surface with densely packed fine pores, while the rest is sealed. The open end of the desiccant box body has a heating cap, and the sieve surface has a sealing cap. The desiccant box body, heating cap, and sealing cap, when combined, form an airtight internal space containing granular color-changing desiccant. The desiccant box body is made of a colorless, transparent, and low-heat-resistant material, and the diameter of the fine pores on the sieve surface is much smaller than the size of the desiccant particles. The heating cap includes a heating cap shell, inside which a heat insulation plate, an electric heating plate, a heat conducting plate, and a light source are installed layer by layer. The top surface of the heating cap shell is flat, and the side has a power interface for supplying power to the electric heating plate and the light source. The function of the heat insulation plate is to prevent heat transfer from the electric heating plate to the heating cap shell, and the function of the heat conducting plate is to evenly diffuse the heat generated by the electric heating plate over a large area. When the desiccant needs to be dehydrated, the heating cap is energized and heats up, causing the desiccant particles inside the desiccant box to gradually dehydrate and change color. The light source facilitates observation of the desiccant's color change effect. The power can be turned off when the desiccant returns to its anhydrous color. When the electrically heated dehydrating desiccant box is in the heating and dehydration state, the sealing cap is removed and the heating cap is placed upright with the heating cap facing down; when storing, the sealing cap is installed; when using, the sealing cap is removed and the entire box is placed in the instrument packaging box.

[0005] Preferably, the power interface of the heating cover adopts the power interface of commonly used portable small electrical appliances such as mobile phones, such as the TYPE-C interface.

[0006] Preferably, the internal surface temperature of the heating cover in the power-on heating state does not exceed 70°C.

[0007] Preferably, the heating cover light source is a white light source.

[0008] Compared with the prior art, the beneficial effect of the present invention is that it can quickly and conveniently dehydrate the desiccant, restore the drying efficiency of the desiccant, and facilitate the reuse and long-term storage of the desiccant. Attached Figure Description

[0012] To illustrate the technical content, objectives, and effects of this application in detail, a specific implementation method is provided below, along with accompanying drawings, to explain the solution.

[0013] Reference Figure 1 , Figure 2 As shown, this application provides an electrically heated dehydrating desiccant box, including a desiccant box body 1. The desiccant box body 1 has a cylindrical structure with a heating cover 2 at the opening, a densely perforated bottom, and a sealing cover 3 on the outside of the bottom. The desiccant box body 1 is connected to the heating cover 2 and the sealing cover 3 by threads. The heating cover 2 includes a circular heating cover shell 4. Inside the heating cover shell 4, a heat insulation plate 5, an electric heating plate 6, a heat conducting plate 7, and a light source 8 are installed layer by layer from the inside out. The heat insulation plate 5 and the heat conducting plate 7 are mainly circular, and the diameter of the heat conducting plate 7 is smaller than the diameter of the heat insulation plate 5. The heat conducting plate 7 does not directly contact the heating cover shell 4. The heating cover shell 4 has a power interface on its side to supply power to the electric heating plate 6 and the light source 8. The function of the heat insulation plate 5 is to prevent the electric heating plate 6 from transferring heat to the heating cover shell 4, and the function of the heat conducting plate 7 is to evenly diffuse the heat generated by the electric heating plate 6 to a large area to avoid local overheating. When the desiccant needs to be dehydrated, the heating cover 2 of the electric heating dehydration desiccant box should be placed upright with the desiccant facing downwards, allowing it to sink and contact or approach the heat-conducting plate 7. Then, remove the sealing cover 3. The heating cover 2, when energized, heats the desiccant particles, causing them to gradually dehydrate and change color. The light source 8 facilitates observation of the desiccant's color change effect. Once the desiccant returns to its anhydrous color, the power can be disconnected, and the entire electric heating desiccant box can be placed inside the instrument case. If it is not necessary to place it inside the instrument case, the sealing cover 3 should be installed to prevent the desiccant from contacting outside air.

[0014] Technical features not described in this application can be implemented using existing technology, and will not be elaborated upon here. Of course, the above description is not intended to limit this application, nor is this application limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this application should also fall within the protection scope of this application.
