[0026] (III) Beneficial effects

[0027] Compared with the prior art, the present invention provides a multifunctional moisture-proof electric meter box, which has the following beneficial effects:

[0028] (1) The multifunctional moisture-proof electric meter box has a humidity sensor which detects the air humidity inside the electric meter box casing. When the humidity is too high, the humidity sensor will drive the exhaust fan to start working, and then the exhaust fan will discharge the humid air inside the electric meter box casing. In this way, the air inside the electric meter box casing can be prevented from being too humid, and the internal equipment of the electric meter box can be prevented from malfunctioning due to the influence of humid air, thereby improving the service life of the equipment and ensuring the measurement accuracy of the electric meter.

[0029] (2) The multifunctional moisture-proof electric meter box can protect the exhaust fan during operation by means of the protective cover, thereby preventing certain objects from touching the exhaust fan from the bottom, thereby ensuring that the exhaust fan can operate normally.

[0030] (3) In the multifunctional moisture-proof electric meter box, external air will enter the interior of the drying box, and then the desiccant inside the drying box will absorb the moisture in the air. Finally, the dehumidified air will enter the interior of the electric meter box shell through the air inlet slot, thereby reducing the humidity of the air entering the interior of the electric meter box shell.

[0031] (4) The multifunctional moisture-proof electric meter box moves the baffle by pulling the control slot, and then the baffle will open. At the same time, the baffle will drive the support rod to move, and wait until the lower side of the support rod moves to the position of the limit slot and stops. Then the support rod will adapt to the limit slot to form a snap connection, and then the support rod will support the baffle, so that the baffle can be easily and conveniently opened for a long time.

[0032] (5) When the air is too humid in rainy weather, the staff of the multifunctional moisture-proof electric meter box moves the support rod and then takes the lower side of the support rod out from the inside of the limit groove, so that the support rod can no longer support the baffle. After that, the baffle can be closed and the baffle will block the fixed shell, so as to avoid humid air from entering the inside of the electric meter box shell through the drying box as much as possible, further reducing the situation where the air inside the electric meter box shell is too humid.
