[0019] As Figures 1 to 5As shown in the figure, in this embodiment, the utility model includes a housing 1 and a heating module 2 disposed within the housing 1. The housing 1 includes a lower housing 3 and an upper cover plate 4 adapted to the lower housing 3. The lower housing 3 includes a bottom plate 5, a left side plate 6, a right side plate 7, a front side plate 8, and a rear side plate 9. The bottom plate 5, the left side plate 6, the right side plate 7, the front side plate 8, and the rear side plate 9 together enclose a receiving cavity 11 with an opening 10. In this embodiment, the bottom plate 5, the left side plate 6, the right side plate 7, the front side plate 8, and the rear side plate 9 are integrally designed. In this embodiment, first recesses 12 are provided on both the front side plate 8 and the rear side plate 9. A second recess 13 corresponding to the first recess 12 is provided on the side surface of the upper cover plate 4. The upper cover plate 4 and the lower housing 3 are hinged by a hinge member 14. The connecting ends of the hinge member 14 are respectively disposed in the first recess 12 on the rear side plate 9 and the second recess 13 on the rear side of the upper cover plate 4. A buckle 15 is provided at the second recess 13 on the front side of the upper cover plate 4. A buckle fixing seat 16 adapted to the buckle 15 is provided at the first recess 12 on the front side plate 8. After the upper cover plate 4 covers the opening 10, the buckle 15 is snapped onto the buckle fixing seat 16. In this embodiment, the buckle 15 is hinged to the front side of the upper cover plate 4, and a bayonet 27 is provided on the buckle 15. A protrusion 28 adapted to the bayonet 27 is provided on the buckle fixing seat 16 where it is snapped. After the upper cover plate 4 covers the opening 10, the protrusion 28 is inserted into the bayonet 27.

[0020] In this embodiment, the heating module 2 is located within the receiving cavity 11, and the receiving cavity 11 is filled with moisture-absorbing particles 17. In this embodiment, through holes 18 communicating with the receiving cavity 11 are provided on both the bottom plate 5 and the upper cover plate 4. The through holes 18 can serve as moisture-absorbing holes or moisture-discharging holes under different usage working states. Adopting the technical solution of the utility model enables the user to have two usage methods: ① Quickly replace the moisture-absorbing particles. When the user needs to quickly use the moisture-absorbing card for dehumidification, the user can directly open the upper cover plate 4, pour out the moisture-absorbing particles 17 that have become saturated with moisture in the receiving cavity 11, place the moisture-absorbing particles 17 saturated with moisture in a high-power drying device for quick drying, or directly use the spare dry moisture-absorbing particles 17. After pouring the dry moisture-absorbing particles 17 back into the receiving cavity 11, fasten the upper cover plate 4, and then put the moisture-absorbing card into the moisture-proof box to continue dehumidification to cope with the situation of urgent dehumidification; ② Regenerate the moisture-absorbing particles. Take the moisture-absorbing card out of the moisture-proof box, then connect the moisture-absorbing card to a 220V AC power supply to make the ceramic heating element in the heating module 2 heat up, so that the moisture-absorbing particles are fully regenerated and dried by heating. Disconnect the power supply and let the moisture-absorbing card stand still to cool down, and then put the moisture-absorbing card back into the moisture-proof box for moisture absorption.

[0021] In this embodiment, the moisture-absorbing particles 17 are color-changing moisture-absorbing silica gel particles. The main component of the color-changing moisture-absorbing particles is silica, which is a material with a dense microporous structure and can adsorb moisture in the air, thereby achieving the effect of moisture absorption and drying. When the silica gel absorbs moisture to a certain extent, if cobalt chloride is attached to the particles, it will show different colors according to the moisture content. Specifically, cobalt chloride appears blue in the dry state. When it absorbs moisture, it forms CoCl2·6H2O, which appears pink. As the moisture absorption increases, the color gradually changes from blue to purple and finally to light red, thus intuitively indicating the humidity of the environment and the moisture absorption degree of the silica gel. In this embodiment, an observation area 24 is provided on the bottom plate 5, and a plurality of observation holes 26 communicating with the accommodation cavity 11 are provided in the observation area 24. Users can see the color of the color-changing moisture-absorbing silica gel particles through the observation holes 26, and then judge whether it is necessary to replace or regenerate the color-changing moisture-absorbing silica gel particles.

[0022] In this embodiment, after the upper cover plate 4 covers the opening 10 and the buckle 15 is clamped to the buckle fixing seat 16, the buckle 15 and the fixing seat 16 will not protrude from the top of the first recess 12 or the top of the second recess 13. In this embodiment, the hinge member 14 will not protrude from the top of the first recess 12 or the top of the second recess 13. In this embodiment, the housing 1 is in the shape of a cuboid. Through the above design, different placement requirements of the moisture-absorbing card in the sealed cabinet can be realized, that is, it can be placed flat, or it can be placed upright, or it can be placed upright with different sides, and it is very flexible and convenient to use.

[0023] As Figure 4 and Figure 5 shown, in this embodiment, four support protrusions 19 are provided on the outer side surface of the bottom plate 5. The heating module 2 includes a control board 20, a ceramic heating element 21 electrically connected to the control board 20, and a heat conduction plate 22 attached to the ceramic heating element 21; the control board 20 is fixed on the inner side surface of the bottom plate 5, and a plurality of support columns 23 are provided on the inner side surface of the bottom plate 5. The heat conduction plate 22 is fixedly arranged on the top of the support columns 23, and the ceramic heating element 21 is attached to the lower surface of the heat conduction plate 22. In this embodiment, a power supply interface 25 is provided on the bottom plate 5, and an external power supply is electrically connected to the control board 20 through the power supply interface 25. Through the design of the heating module 2 described above, the regeneration of the moisture-absorbing particles can be realized, that is, the moisture-absorbing card is taken out of the moisture-proof box, and then the moisture-absorbing card is connected to the power supply, so that the ceramic heating element in the heating module 2 generates heat, and the heat generated by the ceramic heating element is conducted out through the heat conduction plate 22, which can accelerate the regeneration speed of the moisture-absorbing particles.

[0024] Although the embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
