Description of the invention: [Technical field to which the invention pertains] The present invention relates to a microgear pump having a composite toothed rotor, and more particularly to an active rotor and a driven rotor having two different tooth combinations. The two rotors are placed in the rotor casing and mesh with each other to achieve volumetric efficiency and smooth operation during operation, so that the micro gear pump can fully utilize the invention design. [Prior Art] Among the various micro-pulls, a few use non-mechanical driving methods, such as Ultrasonic, Thermocouple, Electroosmotic, etc., most of which use thin films. The squeak is called the driver's micro-pull, and in the film-driven micro-pull, there are piezoelectric (Piezoelectric) (US patent 6867532), electrostatic 弋 (Electrostatic) (US patent 6435840), diarrhea (Thermopneumatic ), electromagnetic (Electr〇 magnetic), shape memory alloy (SMA) and other different forms, and the performance of various different driving forms of micro-pumps, piezoelectric or electrostatic force driven micro-pull, due to The structure is simple and efficient, and there are many applications. The driving principle of the film-driven micro-pull is that when the actuator is energized, the electrode (c〇unter electr〇de) or the piezoelectric piece (piezo disk) will contract and expand. The phenomenon, which in turn causes the film to reciprocally compress the pump room, and controls the flow of fluid into and out through the check valve. Many of today's micro-pulls are made of jingle materials. The film is actuated, 4 1287603 and with different inlet and outlet (Inlet/0utlet) to control the flow = process technology and can not use high elastic film material
