Electronic dampproof box

Abstract

Electronic moisture-proof box possesses lockable cabinet as main body for depositing articles. A cabinet door capable of being opened and closed is setup in the cabinet. Display screen for temperature and humidity, and operational buttons for setting up temperature and humidity are setup on the control faceplate. There are microprocessor and components for sensing temperature and humidity inside the control faceplate. Moreover, there is control expansion board in use for connecting the control faceplate to semiconductor refrigerator inside the electronic moisture-proof box. Through the control expansion board, the semiconductor refrigerator is connected to circuit of the power supplier, which possesses function of AC-DC conversion. Reducing number of opening or closing cabinet door, the invention displays raises accuracy for displaying actual humidity inside cabinet, and reduces influence on dehumidification and moisture control.

Description

technical field [0001] The present invention relates to an electronic moisture-proof box, in particular to a humidity value set via a control panel, and a microprocessor compares the actual humidity value sensed by the humidity sensing element with the preset parameter value as a semiconductor The basis for whether the refrigerator must be operated, so as to realize the electronic moisture-proof box that can accurately display the humidity and control it. Background technique [0002] In the existing technology, we will come into contact with or use some precious and sophisticated electronic products, or commemorative collections. These items usually need to be placed in a safe place to avoid unnecessary collision damage. , it is also necessary to pay attention to avoiding the damage of moisture, because moisture is invisible to the naked eye. When people feel that the object is damaged by moisture, the damage of moisture to the object is often irreparable; for example: opti...

[0004] The traditional electronic moisture-proof box is provided with a pointer type hygrometer 20 at the box door 11, and dehumidification control is carried out in an analog signal transmission mode; however, the pointer type hygrometer 20 is only used to display the humidity value inside the moisture-proof box, and the whole The setting of the humidity value is controlled by the humidity setting knob (not shown) inside the cabinet 10, that is, the user adjusts the humidity setting knob according to the humidity value displayed by the pointer hygrometer 20, so it must be opened repeatedly The box door 11 is not only extremely inconvenient to use, but also the actual use effect is extremely unstable, which greatly reduces the effect of dehumidification and humidity control
