Specifically, the number of the fuel cell units 211 may be one, two, three, or more, and when the fuel cell units 211 are multiple, the fuel cell units 211 may be sequentially connected in series, so as to increase the charging voltage and power of the fuel cell units 211, and shorten the time for the earphone charging box to charge the wireless earphone. In addition, because the energy density of the fuel cell 21 is significantly higher than that of a conventional lithium ion battery or other batteries, for example, the energy density of a methanol fuel cell is about three times of that of a lithium ion battery, and the fuel cell 21 can be converted from a low-capacity state to a high-capacity state under the condition of rapidly replenishing the battery fuel, the wireless headset can be charged at any time.
The embodiment of the application provides earphone box of charging is through set up in the battery compartment 2 fuel cell 21, fuel cell 21 can realize right wireless earphone's quick charge, moreover because battery fuel replenishment process in the fuel cavity 212 is shorter, can guarantee earphone box of charging's duration improves user's use and experiences.

Specifically, in order to improve the efficiency of the flow guide structure 3 in delivering oxygen, the flow guide structure 3 may further include a flow guide structure surrounding the peripheral side of the fuel cell 211.

Taking a methanol Fuel Cell (DMFC) using a Cell Fuel as methanol as an example, on one hand, when the methanol Fuel Cell supplies power to the earphone charging box, the wireless earphone can be charged as long as a methanol solution is ensured in the Fuel cavity 212, so that the earphone charging box can rapidly charge the wireless earphone, the cruising ability of the earphone charging box is ensured, and the methanol solution can be directly injected into the Fuel cavity 212 for supplementing, so that the supplementing process can be rapidly completed; on the other hand, the energy density of a methanol fuel cell is about three times that of a conventional lithium ion battery, and thus, the methanol fuel cell has a longer endurance than the lithium ion battery with the same volume.
Specifically, the power generation principle of the methanol fuel cell is as follows:
anode: CH (CH) 3 OH+H 2 O→CO 2 +6H + +6e －

When the fuel cavity 212 is filled with the battery fuel, the inverted trapezoidal bottom surface of the lower end of the valve core 42 is separated from the lower end opening, and the external battery fuel can flow to the fuel cavity 212 from the one-way valve 4 through a methanol liquid inlet pipeline, so that the battery fuel in the fuel cavity 212 can be supplemented; after the fuel cavity 212 finishes filling the battery fuel, the battery fuel in the fuel cavity 212 can abut against the valve core 42, so that the inverted trapezoidal bottom surface of the valve core 42 abuts against the lower end opening, and the leakage of the battery fuel in the fuel cavity 212 is avoided.

When it is necessary to add battery fuel into the fuel cavity 212, the delivery pressure of the external fuel pushes the valve core 42 upward, and the battery fuel enters the valve core 42 from the bottom of the check valve 4, passes through the opening at the top of the valve core 42 and the through hole of the baffle 43, reaches the liquid inlet pipeline, and finally is supplemented to the fuel cavity 212. When the fuel cell needs not to be added to the fuel cavity 212, the spring 44 in the check valve 4 pushes the valve core 43 downward, so that the inverted trapezoidal bottom surface of the valve core 42 abuts against the lower end opening, and the fuel cell in the fuel cavity 212 is prevented from leaking.
