An agentia distributor comprises a basic shell, a circuit device and a dividing wheel rotatable in the basic shell, wherein the basic shell comprises a suction nozzle, an air flowing path communicatedwith the suction nozzle is defined in the basic shell, the circuit device is arranged in the basic shell and comprises a first circuit board and a pressure sensor arranged on the bottom surface of the first circuit board and located in the air flowing path, the pressure sensor is used for sensing the air pressure in the air flowing path, and multiple grooves arranged at intervals of equal anglesare formed in the dividing wheel and are used for accommodating corresponding agentia bags on an agentia belt. When the dividing wheel rotates to a position for suction, a user can suck agentia in oneof the agentia bags through the suction nozzle, and at the position for suction, one of the grooves of the dividing wheel enables the downstream side position of the pressure sensor to be communicated with the air flowing path.
