The real wireless earphone belongs to a daily wearable product used at high frequency, however, a user often ignores active preventive measures due to weak safety consciousness, and the real wireless earphone is easily splashed by domestic water, rainwater or sweat and the like. Therefore, when the real wireless earphone is charged, the Pogo Pin (namely the spring Pin connector 20) of the charging bin is subjected to electrolytic corrosion due to accumulated liquid, and the service performance and the service life of the product are greatly reduced.
The existing solution is to improve the electrolytic corrosion resistance of the product by continuously optimizing the plating performance of the surface of the Pogo Pin, but the cost of raw materials is increased to a certain extent.
Therefore, the problems that the Pogo Pin of the conventional wireless device charger is easy to be subjected to electrolytic corrosion due to accumulated liquid, and the service performance and the service life of the product are greatly reduced need to be solved.

In this embodiment, the control Unit 10 is a micro controller Unit (MCU, also called a single chip microcomputer). The main function of the control unit 10 is to control the fault reminding unit 40 to notify the user to clean the electrical connector after receiving the fault parameter sent by the first connection end. It should be noted that the control unit further includes a wireless communication module capable of establishing a communication connection with a terminal device of a user and sending a reminding message for cleaning the electrical connector to the terminal device. Specifically, the Wireless communication module may be a WI-FI (Wireless-Fidelity) module, or a bluetooth module.

The electric connector has various types such as a fixed pin connector and a pogo pin connector 20 having a telescopic function, etc. In this embodiment, the wireless device is a wireless headset, and the electrical connector is a Pogo pin connector 20 (i.e., Pogo pin). The wireless earphone can be charged by correspondingly contacting the female end (or the male end) of the spring pin on the wireless earphone with the male end (or the female end) of the spring pin connector 20.

For example, the display panel displays a text of "please check whether the spring needle has accumulated liquid and process in time" to remind the user.
It is understood that the fault notification unit 40 may be other devices in other embodiments. For example, a sounder device may be used to implement the function of a message alert. In particular, the sound-emitting device may be a loudspeaker.

In other embodiments, the fault notification unit 40 may be other devices. For example, a light emitting device (e.g., an LED lamp) may be used to implement the message alert function. Specifically, after the control unit 10 receives the fault parameter, the control unit 10 sends a level control signal to the LED lamp, and the LED lamp may remind the user of the information for cleaning the pogo pin connector 20 in a manner of flashing, lighting, or the like. It should be understood that the number of LED lamps is not limited to one, and may be one or more, as long as the user can be reminded to clean the pogo pin connector 20.
It should be noted that the fault notification unit 40 may also be implemented by combining various devices to notify the user to clean the pogo pin connector 20. For example, the reminding can be realized by simultaneously displaying characters through the display panel and playing voice through the loudspeaker, or simultaneously realizing the reminding by flashing the LED and playing voice through the loudspeaker.
In this embodiment, the second connection end of the fault detection circuit 30 is electrically connected to the electrical connector, and receives an abnormal current signal of the electrical connector, the abnormal current signal is converted into a fault parameter through internal processing of the fault detection circuit 30, and the fault parameter is output to the control unit 10 through the first connection end of the fault detection circuit 30, so that the control unit 10 controls the fault reminding unit 40 to notify a user to clean the electrical connector. In the embodiment, the fault detection circuit 30 actively detects the abnormal current of the electrical connector, and sends necessary reminding information to the user through the fault reminding unit 40 to help the user correctly use the product, thereby avoiding electrolytic corrosion of the pogo pin connector 20 of the wireless device charger due to effusion, improving the service performance of the product and prolonging the service life of the product.
