Aiming at the problems of limited purification range, fixed structure, the need to match various indoor cleaning equipment (such as sweeping robot) and high space and economic cost of the existing air purifier, an integrated multi-functional air purifier was designed and developed. In traditional sweeping robot by MCU and air purification part, on the basis of serial communication using various sensors to collect environmental data terminal node, the coordinator node after the analysis of the data processing, single chip microcomputer to working mode to make smart choices, enhance the ductility of the product function, the realization of the innovation the location tracking and purification of sudden pollution sources; Cooperate with the self-developed APP interactive end to improve the user experience; Unique air outlet design effectively solves the problem of weak air convection in small air purifier.
