1. A wireless charging device, comprising:
a device body comprising a top wall, a bottom wall and a first airflow outlet, wherein the top wall and the bottom wall are opposed to each other, and the first airflow outlet is formed in the top wall;
a covering member installed on the device body, wherein an airflow channel and a second airflow outlet are defined between the covering member and the device body, wherein the airflow channel is in communication with the first airflow outlet and the second airflow outlet, and the second airflow outlet is located under the bottom wall of the device body;
a fan module installed within the covering member, wherein the fan module has an air outlet, and the air outlet faces the airflow channel; and
an airflow adjustment element installed on the bottom wall of the device body and disposed within the airflow channel, wherein the airflow adjustment element is extended in a direction toward the air outlet of the fan module, and the airflow adjustment element is aligned with the air outlet of the fan module, wherein when an airflow produced by the fan module is blown out from the air outlet, the airflow is split into a first-portion airflow and a second-portion airflow by the airflow adjustment element, wherein a flowing direction of the first-portion airflow and a flowing direction of the second-portion airflow are different, the first-portion airflow flows out of the first airflow outlet, and the second-portion airflow flows out of the second airflow outlet.
