When the compression unit is started to be sucked by the motor unit, the fluid outside the valve unit is sucked by the radiation recess, and the suction valve is pushed open and then enters the compression unit through the inlet and outlet holes. S [When the unit X motor unit is driven to start compression, the body in the compression unit 7L is discharged outside the valve unit through the inlet and outlet holes and the discharge gap and pushes the discharge valve open. [Embodiment] The present invention provides a more efficient micropump device, which improves the efficiency of the micropump by improving the airtightness of the inlet and outlet valves and shortening the fluid intake and discharge paths. The structure and function of the micro pump will be described below by way of examples. Please refer to Figure 1 for an exploded view of a micropump according to an embodiment of the present invention. The micropump 100 can be roughly divided into a motor unit, a two valve unit, and a compression unit. The motor unit provides the power source required for the mini-fruit and drives the mechanism within the compression unit so that fluid can be drawn into or out of the micropump via the valve unit. The motor unit 70 includes a motor cymbal 26, a pump housing 24, a transmission shaft 12A, a rotating shaft 116, and a slant arm link 114. The motor 126 is attached to the 6 200817588 pump base 124 by means of a screw 122. The drive shaft 120 is fixed to the motor ι26, and the rotating shaft 116 and a steel ball 118 are then filled into the shaft hole of the transmission shaft 120. The bottom end of the inclined arm link 114 is fixed to the rotating shaft 116 such that the inclined arm link 114 can drive the power of the motor 126 to drive the mechanism in the driving compression unit. Since the shaft hole is at a small angle with the rotation shaft of the motor 126, the shaft 丨丨6 makes a pointed cone motion, which in turn drives the angled arm link 114 to also rotate in a conical shape. When the inclined arm link 114 is rotated, the arm portion of the inclined arm link 114 is, for example, moved up and down to press or stretch the three compression cylinders 110. The compression unit includes a compression cylinder 110 and a compression cylinder block 112. The compression cylinder 11 is a compressible compression cylinder whose bottom end is connected to the arm U4a of the inclined arm link 114. When the motor 126 drives the ramp arm link 114 to rotate, the three compression cylinders 110 will be squeezed or stretched by the passive ramp arm link 114. The compression cylinder 11 is assembled in the recess of the compression cylinder block 112 and is fixed under the valve seat 1〇8. Although the present embodiment has three compression cylinders 11 〇, other numbers of compression cylinders can be used as needed. The valve unit includes an inlet and outlet valve 106 and a valve seat 1〇6 assembled to the valve seat 108 to provide a suction and discharge path for the fluid. When the motor unit, the valve unit and the compression unit are assembled, the motor 126 and the pump base 124 are first fixed by using the screw 122, and the components are first superposed, and then the upper end of the hook 1〇2 is firstly engaged with the upper cover 1〇4. The other end of the hook 102 is then engaged with the pump base 124. In order to fix the components of the micropump with the hooks 1 〇 2, the upper cover 1 〇 4 door seats 108, the compression cylinder block 112 and the circumference of the pump base 124 structure, and the engagement grooves are fixed for the hooks 102 to be fixed. In addition to the 2 elements of the hook 1〇2 mini fruit, the components of the micropump can also be screwed. In May, reference is made to the section of the second ® '''''''''' This figure contains a cross-sectional view of the micropump after assembly (bottom left) and an enlarged view of the inlet and outlet valve sections (top right). The mechanism by which the micropump drives the fluid is that the pressure in the compression cylinder is returned to or lower than the pressure outside the micropump by the compression reduction or the stretching amplification of the compression cylinder 110, so that the fluid can be sucked in or discharged from the compression cylinder. The compression of the compression cylinder 110 is reduced or stretched to amplify the drive from the torque of the motor 126. The connecting portion 11a of the compression cylinder 110 is coupled to one of the arm portions 114a of the inclined arm link, so that the torque of the motor 126 is transmitted to the compression cylinder 11 () via the transmission shaft 12, the rotating shaft 116, and the inclined arm link 114. Ο Ο Referring to FIG. 3, an enlarged view of a valve seat and an inlet and outlet valve of a micro pump according to an embodiment of the invention is shown. This figure also shows the inlet and outlet valves 1% and the upper and lower sides of the valve seat 108. The valve seat 108 includes an inlet and outlet 109 and a cylinder lu. The inlet and outlet holes 1〇% and the cylinder 111 are both formed within 1〇% of the circular recess of the valve seat 1〇8. The cylinder 1 has three discharge notches 109a on its annular outer wall. The inlet and outlet hole 109 is only shown in the lowermost valve seat; in the other view of the valve seat, the inlet and outlet hole 109 is located in the circular depression l〇9c of the lower discharge side of the three discharge gaps (not drawn) Shown on the map). The three radiating recesses l〇9b extend outward from the circular recessed position, so that the three radiating recesses are connected to the inlet and outlet holes 109. The three elliptical positioning depressions are respectively three (four) shaped recessed parts. One of the three inlet and outlet holes 109 of one side of the valve seat 108 is used for engagement with the three compression cylinders 11A, respectively. Please also refer to Figures 3 and 4. The inlet and outlet valves 1〇6 contain ten = tube and - disc parts. The hollow circular tube portion penetrates the middle portion B' of the disc portion, and the diameter of the hollow circular tube portion on both sides of the disc portion is different, and the hollow circular tube portion of the diameter is - suctioned into the width 107, the smaller the diameter of the tube; Tube: 200817588 is a discharge valve 1 〇 6a. In and out of the reading The inner wall of the suction reading 1〇7 has three partitions on the lion of the disc. The second two 106 includes three positioning portions to include the above structures. 06 can be a one-piece design. Seat == 2 and 31st. When the inlet and outlet valves are installed in the valve 1〇8, the dotted line indicates that the inlet and outlet valve 106 is assembled to the valve seat, and the outer wall of the suction valve 107 contacts the garment-shaped inner wall 109d of the circular recess l〇9c, and drains.

At the same time, the three positioning portions are engaged with the three 疋=recesses 108b; the three partitions 1〇7a are also fitted to the outer wall 111a of the cylinder (1) for isolating the fluid in the three radiation-like depressions. When the pressure of the compressed red 110 is lower than the pressure outside the micropump, the suction path of the fluid passes through the suction hole and the muffler chamber, and then flows into the three radiating recesses 109b, respectively, and then pushes in the suction valve. 7 enters the three inlet and outlet holes 109b, respectively, and finally enters the three compression cylinders 11b. When the dust force of the compression cylinder 110 is higher than that of the micro-fruit, the fluid discharge path 103b passes through the discharge slit 109a to push the discharge valve 1〇6a and exit the micro-pump through the discharge hole 104c. Figure 5 is an enlarged view of a top cover of a micropump in accordance with an embodiment of the present invention. This figure includes the upper and lower sides of the upper cover 104. The discharge hole 104c is located in the central area of the upper cover 104, and the suction hole 1 〇 4b is located in the area of the edge of the upper cover 1 〇 4 杈. The upper cover 1 〇 4 includes a hermetic partition wall 4e and a silencing partition wall 1 〇 4d constituting the muffling chamber 104a. It can be seen from the above embodiments of the present invention that the micropump of the present invention is designed to make the valve more airtight by the 200817588 round tube type suction valve and the round tube type discharge valve. In addition, the inlet and outlet valves include a tubular inlet valve, a discharge valve and a disc portion, so that the suction path and the discharge path only need to be the same as the through hole, and the discharge path can pass through the central portion of the valve seat. This will further improve the efficiency of the micropump. Although the present invention has been described above in terms of a preferred embodiment, it is not intended to limit the invention, and it is obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
