Description of the Invention: [Technical Field] The present invention relates to a micro-pump, and more particularly to a flat micro-type of an axial magnetic body in which a magnet is integrated into an impeller and a coil is fitted to the housing. Type Lipu. [Prior Art] The structure of the conventional centrifugal puddle generates a magnetic field by inputting a current from a coil on the stator, and a magnetic force acts on the magnet on the rotor to drive the impeller to rotate, thereby causing the fluid to flow, depending on the motor setting of the pump. It can be roughly divided into external motor pump and interpolated motor pump, and its advantages and disadvantages are as follows: Please refer to the prior art external motor pump as shown in FIG. 1A. The external motor pump 10 series adopts the motor 12 and the pump body to be separated and designed to transmit power through the transmission shaft. The fluid 13 is introduced from the center and centrifugally pushed out through the rotating impeller 11 , and has the advantages of easy assembly and leakage. However, if the required combination space is relatively large and the transmission shaft becomes long, it is difficult to align the shaft of the motor 12 with the axis of the impeller 11 . If the shaft of the motor 12 is not aligned with the axis of the impeller 11, vibration noise is reduced and reduced. Its life. Referring again to the prior art interposer motor pump illustrated in FIG. 1B. The interpolated motor pump 10 system embeds the motor 12 at the axial position of the impeller 11, and the diameter of the motor 12 is limited by the blade shape, resulting in a limitation of the torque output. If the diameter of the motor 12 is to be increased, the blade shape is compressed. This results in a limited flow or pressure output of the fluid 13. Further, since the motor 12 is limited to the axial center of the impeller 11, the heat generated during operation is not easily dissipated, which is liable to cause 4 201024551. The motor overheats and affects the service life. SUMMARY OF THE INVENTION A flat micropump, and pressure' is called volume. The problem to be solved by the present invention is to provide a flat miniaturization with a high output torque and a high fluid outlet.
