Description
Technical Field

These devices often require frequent charging, and wireless chargers can provide a very convenient way of charging these devices, so the demand for wireless chargers is increasing.
The wireless charger is a device for charging by utilizing the electromagnetic induction principle, and the principle is similar to that of a transformer, and the wireless charger achieves the purpose of wireless charging by arranging a coil at each of a transmitting end and a receiving end, wherein the coil at the transmitting end sends electromagnetic signals to the outside under the action of power, and the coil at the receiving end receives the electromagnetic signals and converts the electromagnetic signals into currents.
The mobile phone battery generates heat through chemical reaction in the battery during charging, so that the battery is prevented from being charged and overheated, the safety requirement on a wireless charger is gradually improved along with the improvement of the safety consciousness of a user, the charging safety problem is the primary problem of the wireless charger, and in the prior art, the protection of the mobile phone is realized by adopting an automatic power-off mode;

(1) Poor radiating effect after active power failure: the wireless charger charges by generating and transmitting a high-frequency electromagnetic field, the electromagnetic field is transmitted through air and the charging panel, and part of electromagnetic energy is converted into heat energy, so that the charging panel heats, and the lithium ions of the lithium battery release heat energy in the reaction, so that the charging panel of the wireless charger and the battery of the mobile phone both heat, and even if the wireless charger is powered off, the heat dissipation effect of the charging panel and the mobile phone is still poor;
(2) The mobile phone cannot be safely separated from the charging panel: the charging panel of the wireless charger and the mobile phone are both used as heat sources, after the charging panel and the mobile phone are in contact with each other, the gap in the middle is small, heat is difficult to dissipate, if the mobile phone is separated from the charging panel in a mode of bouncing the mobile phone, the risk of colliding with the mobile phone can exist, and if the mobile phone is not separated from the charging panel, the heat dissipation of the mobile phone can be influenced.
For example, the techniques disclosed in CN202222469847.7, a desktop wireless charger with overheat protection structure, and CN202222146166.7, a wireless charger overheat protection device, are both core in that the heat dissipation of the wireless charger is achieved by the heat dissipation airflow, but the airflow cannot flow between the charging panel and the mobile phone, so only one of the wireless charger and the mobile phone can be dissipated, and the above technical problems cannot be satisfied.
