Wireless window intercom device with replaceable battery and emergency charging interface

Abstract

The invention relates to a wireless window intercom device with replaceable battery and emergency charging interface, realizing talkback of users inside and outside a window by the electronic parts of a main machine and a secondary machine. The secondary machine is powered by the replaceable battery, and the main machine is used for substituting the replaceable battery to charge the secondary machine and is used for interchange of the replaceable batteries alternately. When the replaceable battery can not charge the secondary machine, the main machine charges and supplies power to the secondary machine by virtue of the emergency charging interface. The main machine is powered by electric supply, and the contained high capacity battery can supply power to the main machine and secondary machine when electric supply is cut off, so that wireless window talkback function can be ensured to be normal in a long time even if the electric supply is cut off. Talkback function is closed, the replaceable battery in the secondary machine can be charged by the electric supply or the high capacity battery in the main machine by virtue of the emergency charging interface, thus ensuring that the replaceable battery in the secondary machine has enough electricity when being used at the next time.
