The invention relates to an intelligent air purifier with excellent circulation performance based on Internet of Things. The intelligent air purifier comprises a shell and a chassis, wherein the shellis fixed above the chassis; the shell is internally provided with an air inlet tank, a filtering mechanism, a treatment mechanism and an air outlet tank; the chassis is internally provided with a bottom plate, a power mechanism and two adsorption mechanisms; the filtering mechanism comprises a filtering tank and a cleaning component; the adsorption mechanisms comprise exhaust fans, exhaust tubes,air outlet tubes, lifting tubes, connecting tubes and suckers. According to the intelligent air purifier with excellent circulation performance based on Internet of Things, a filtering net is cleanedthrough the cleaning component, so that the circulation capability of air flowing through the filtering net is improved, the frequency of replacing the filtering net is reduced, and the cost is reduced; compared with a conventional cleaning component, the cleaning component is capable of intelligently changing a working direction and is relatively high in working efficiency, and in addition, theadsorption mechanisms are supported by the power mechanism to be adsorbed to the ground, then the air purifier is prevented from being pushed down, security accidents are avoided, and the stability ofthe air purifier is improved.
