Claim:
1. An airflow concentrator for an electric hairdryer, comprising: an airflow divider which is adapted for connecting with the electric hairdryer, wherein an airflow generated by the electric hairdryer is divided and deflected by said airflow divider to two airflows to be flowed out of said airflow divider at an altered flowing direction different from the flowing direction generated from the electric hairdryer; two connecters which are connected with said airflow divider, said two connectors are inclined towards a center line of said airflow concentrator respectively; and two airflow nozzles which are adjustably connected with said connecters respectively, wherein said airflow from said airflow divider is deflected and then flowed out thereof, wherein said airflow, which is generated by said electric hairdryer and flows into said airflow divider, is divided and deflected in said airflow divider and flows out of said airflow divider, wherein said airflows being divided and deflected in said airflow divider flow into said two airflow nozzles through said connecters respectively, are deflected in said airflow nozzles respectively, and flow out of said two airflow nozzles respectively, each of said airflow nozzles further comprising: an airflow nozzle connecter, which is connected with said respective connecter so as to enable said airflow from said respective divider outlet of said respective airflow divider flowing into said respective airflow nozzle through said respective airflow nozzle connecter; a guiding cavity, which is communicated with said respective airflow nozzle connecter, wherein said airflow in said respective airflow nozzle is deflected therein; and an airflow outlet, said airflow being deflected in said guiding cavity flowing out of said airflow nozzle therethrough, wherein said airflow from said airflow divider flows into said respective guiding cavity through said respective airflow nozzle connecter, and flow out said respective airflow outlet after being deflected in said respective guiding cavity, each of said airflow nozzles further comprising a connection portion, a first airflow guiding surface, a second airflow guiding surface, and a pair of protuberances protruded at two side surfaces of said airflow nozzle, said two side surfaces of said airflow nozzle being extended along said connecting portion to said airflow outlet, said two protuberances being respectively located in corresponding positions in said two side surfaces of said airflow nozzle, said first airflow guiding surface being extended from said connecter portion to said airflow outlet, said second airflow guiding surface being extended from said connecter portion to said airflow outlet, said airflow outlet being defined between said first airflow guiding surface, said second airflow guiding surface and said two protuberances of said two side surfaces, each said connecting portion defines a central axis, each said airflow nozzle has an asymmetrical structure formed through a differential angle of curvature between said first airflow guiding surface and said second airflow guiding surface such that said airflow outlet has a central axis different from the central axis of said connecting portion for facilitating airflow deflection;
