The principle of operation of the present invention will now be described as follows: when the Bluetooth earphone is required to be charged, the bin cover 3 is opened, then the two Bluetooth earphones are placed in corresponding positions in the inner shell 2, so that the conductive contacts of the Bluetooth earphone are in contact with the corresponding conductive contact rods 6, then the bin cover 3 is closed, when the bin cover 3 is closed, the top pressing groove column 111 is driven by the bulge 10 to press down the movable column 113, when the movable column 113 moves downwards, the pressure switch 115 is pressed down, and after the pressure switch 115 is closed, the charging control circuit board 4 starts to transmit the electric quantity stored in the battery 5 to the Bluetooth earphone;
in the charging process, if abnormal temperature rise occurs at the contact point of the conductive contact rod 6 and the conductive contact of the Bluetooth headset due to corrosion and the like, heat is quickly transferred to the heat-conducting ceramic plate 7 and is transferred to the corresponding automatic temperature switch 9 through the heat-conducting ceramic plate 7, after the temperature rises to a certain value, a heat-sensing element in the automatic temperature switch 9 can close the contact under the action of thermal stress, and at the moment, the protection switch 19 can be immediately electrified and closed, so that the charging work of the charging control circuit board 4 can be immediately stopped;
the connection loop of the electromagnetic strip 127 and the charging control circuit board 4 is immediately connected after the automatic temperature switch 9 is closed, at this time, the electromagnetic strip 127 can immediately generate magnetic attraction force, so that the iron core 125 can be adsorbed to drive the piston rod 122 to move upwards, the space between the jacking groove column 111 and the piston rod 122 can be increased after the piston rod 122 moves upwards, at this time, under the action of internal and external pressure difference, the air in the inner shell 2 can be sucked into the air suction groove 121 through the air suction hole 123 on the jacking groove column 111, and under the action of the check valve 124, the air sucked into the air suction groove 121 can be prevented from flowing backwards, and after the air in the inner shell 2 is sucked into the air suction groove 121, the oxygen content in the inner shell 2 can be greatly reduced, so that the effect of suppressing open flame can be achieved, the possibility of burning down of the Bluetooth earphone can be reduced, meanwhile, when the piston rod 122 moves upwards, the air in the air suction groove 121 and the installation cavity 126 can be pressed into the frame-shaped sealing groove 131 through the communication hole 133, under the action of air pressure, the abutting end face of the elastic sealing frame 132 and the outer shell 1 can be prevented from entering the inner shell 1, so that the air can be sealed between the cabin cover 3 and the outer shell 1;
meanwhile, after the piston rod 122 is electrified, under the action of magnetic attraction, the iron sheet 153 is adsorbed to drive the pressing block 152 to move upwards for a certain distance, at this time, the pressing block 152 does not apply pressing force to the Bluetooth headset, after the air pressure in the inner shell 2 is reduced, the external air can expand and bulge the elastic membrane 162 towards the inner wall of the inner shell 2 through the air hole 163 under the action of external air pressure, at this time, under the action of the elastic membrane 162, the two Bluetooth headsets can be lifted upwards, so that the conductive contact of the Bluetooth headset is separated from the conductive contact rod 6, and the Bluetooth headset is ensured to be effectively disconnected from the conductive contact rod 6;
and after the electromagnetic strip 127 is electrified, the two conical sealing iron columns 174 are adsorbed to move downwards for a certain distance, at this time, the disinfection fragrance 172 in the liquid storage cavity 171 can escape through the inverted conical hole 173 through volatilization, so that people can be reminded of abnormal conditions of Bluetooth headset charging through fragrance, meanwhile, when the temperature automatic switch 9 is closed, the buzzer 18 is electrified to alarm through hearing, alarm can be sounded, under the action of the timer 20, even if the temperature automatic switch 9 returns to normal temperature after temperature is reduced, under the action of the timer 20, the electromagnetic strip 127 and the buzzer 18 can continue to work until the timing time is over, and in the daily use of the Bluetooth headset, if sweat is adhered to the Bluetooth headset, the sealing cover 22 can be opened, the disinfection fragrance 172 in the liquid storage cavity 171 can be poured out, and the Bluetooth headset is matched with a paper towel to wipe (the disinfection fragrance 172 needs to be replaced and supplemented regularly).
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
