Description of the invention: [Technical field to which the invention pertains] The present invention relates to a micropump device. [Prior Art] = The name of the pump is the same as the volume-reduced version I. Because the size of the miniature motor used can only be a smaller power motor. Therefore, the efficiency of the = system depends on the design of the valve S and the compression unit. The potential disadvantages are: the airtightness of the inlet and outlet valves and the excessive length of the input innovation. The space is waiting for each inferior family. [Inventive content] Therefore, the object of the present invention is to provide a (four) device unit = a two-cell unit, a valve unit, and a - compression unit _, 70. The motor is driven by the early action of the motor to allow the fluid to be sucked in or discharged out of the valve. The door reading unit includes at least one door base and an inlet and outlet two door valve seat connected to the compression unit. The valve seat has at least: two columns formed in it. - Inside the recess. The cylinder has at least - discharge absence =, /, on the outer wall of the garment y. The depression includes - a circular depression and at least - and - a lack of a spherical depression extending outward from the circular depression - and a radiation depression and a discharge gap are connected to the inlet and outlet. Stealing - In and out 'contained' hollow hollow tube part and - disc part T two circle 1312032 The tube part penetrates the middle of the disc part. The hollow circular tube portion has different diameters on both sides of the disk portion. The hollow tube portion of the larger diameter is a suction valve, and the smaller tube portion of the smaller tube is a discharge valve. # When the inlet and outlet valves are assembled in the valve seat, the inner wall of the discharge valve is sleeved to contact the annular outer wall of the cylinder, and the outer wall of the suction valve contacts the annular recessed annular shape [the disc portion covers the circular depression and exposes a portion of the radiation depression. When the suction of the motor unit is started, 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. When the compression unit parent motor unit is driven to start compression, the peach in the compression unit 70 passes through the inlet and outlet holes and the discharge gap, and pushes the discharge valve out of the valve unit. [Embodiment] As described above, the present invention provides a micro-pump device which is more efficient, and 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 micropump will be described below by way of examples. Referring to Figure 1, there is shown an exploded view of a micropump in accordance with an embodiment of the present invention. The micropump 100 can be roughly divided into a motor unit, a valve unit, and a housing unit. The motor unit provides the power source required for the mini fruit and drives the mechanism within the star reduction unit so that fluid can be drawn into or out of the micropump via the valve unit. The motor unit includes a motor 126, a pump base 124, a transmission shaft 12A, a rotating shaft 116, and an inclined arm joint #114. The motor 126 is attached to the 1312032 pump seat 124 by means of a screw 122. The drive shaft 120 is fixed to the motor 126, and the rotating shaft ι 6 and a steel ball 118 are then filled into the shaft hole of the transmission shaft 12A. The bottom end of the inclined arm connector 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 unit. Since the shaft hole is at a small angle with the rotation shaft of the motor 126, the shaft 116 makes a pointed cone movement, which in turn drives the angled arm link 114 to rotate in a conical manner. When the inclined arm link 114 rotates, the arm portion of the inclined arm link 114 moves up and down to press or stretch the three compression cylinders i i . The compression unit includes a compression cylinder 110 and a compression cylinder block 112. The compression cylinder 110 is a compressible compression cylinder whose bottom end is coupled to the arm portion 114a of the inclined arm link 114. When the motor 126 drives the inclined arm link 114 to rotate, the three compression cylinders U0 are pressed or stretched by the passive oblique arm link Π4. 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 embodiment has three compression cylinders 11 〇, other numbers of compression cylinders can be used as needed. The door unit includes an inlet and outlet valve 106 and a valve seat 1〇8. The inlet and outlet valves 1 〇6 are assembled on the valve seat 8 to provide a suction and discharge path for the fluid. When the motor unit, the valve unit and the compression unit are installed, the motor 126 and the pump base 124 are first fixed by screws 122, and the components are first superposed, and then the upper end of the hook is first engaged with the upper cover 1〇4, and then the card is inserted. The other end of the hook 1〇2 is engaged with the pump base 124. In order to fix the components of the micropump with the hooks 1〇2, the circumferences of the upper cover W4, the valve seat 108, the compression cylinder block 112 and the pump base 124 are designed to be fixed by the engagement grooves for fixing the clamps from 1 to 2. In addition to the 7L parts of the hook 1〇2 micropump, the components of the micropump can also be screwed. Referring to Fig. 2, the figure shows the section 1312032 of the assembled micropump of Fig. i. 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 higher 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 into or discharged from the compression cylinder 110. 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 110a of the compression cylinder U is connected to one of the arms 114a of the inclined arm link, so that the torque of the motor 126 is transmitted to the compression cylinder 11 through the transmission shaft 12, the rotating shaft 116, and the inclined arm link 114.

This figure also shows the upper and lower sides of the inlet and outlet valves (7) 6 and the valve seat 108. The wide door 108 includes an access hole 109 and a cylinder m. The inlet and outlet holes 1〇9 and the column ill are formed in the circular recesses i〇9c of the valve seat 1〇8. The circle U1 has three discharge notches l〇9a located at its annular outer wall 11Ui. The other side of the d-hole 109 is shown in the other view of the lowermost door _, and the entrance and exit hole 109 (four) of the three discharge gaps U) 9a are in the bottom of the hole (not shown (four) face). The three radiating shapes (4) b extend outward from the circular recessed position, so the three radiating depressions are all named = the inlet and outlet holes (10). The three ellipses are the secret parts of the three sag. The three inlet holes 109 on one side of the valve seat 1〇8 are used for engagement with the three compression cylinders 11〇, respectively. Refer to Figures 3 and 4 for the case.

When the inlet and outlet valve 1〇6 is assembled to the valve seat 108 (the broken line in the figure shows the corresponding position when the inlet and outlet valve Π1G6 is assembled to the valve seat 108), the outer wall of the suction valve 1〇7 contacts the annular inner wall of the circular recess (10)^ L〇9d The inner wall of the discharge valve 1G6a is fitted into contact with the dome-shaped outer wall 111a' of the cylinder (1) and the disk portion 1Q6b covers the circular recess (10). And expose a part of the radiation depression _. At the same time, the three mosquitoes are engaged with the three positioning recesses 108b; the three partitions 1〇7a are also fitted to the annular outer wall 111a' of the cylindrical iu to isolate the fluid in the three radiating recesses. When the pressure of the compression cylinder 110 is lower than the pressure of the micro-sugar, the suction path 103a of the fluid passes through the suction hole 104b and the muffler chamber, and then flows into the three radiation depressions 1〇9b, respectively, and then pushes open. The inlet valve ι〇7 enters the two inlet and outlet holes 1〇9b, respectively, and finally enters the three compression cylinders 110, respectively. When the pressure of the compression cylinder UG is higher than that of the micro-system, 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 contains the upper and lower sides of the upper cover 1〇4. The discharge hole i〇4c is located in the central area of the upper cover 104, and the suction hole 1〇4b is located in the region of the upper edge of the upper cover ι4. The upper cover 104 includes a hermetic partition wall 1〇4e and a silencing partition wall 1〇4d constituting the muffler 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 1312032 = s 5L suction valve and the circular discharge valve design. The _ inlet and outlet valve includes a 1-tube suction valve, a discharge valve, and a disc portion. The suction and the discharge path only need to share the same as the through-hole, and the discharge path can pass through the central portion of the valve seat. In order to promote efficiency, it can be better. The present invention has been disclosed in the above-described preferred embodiments, and it is not intended to limit the invention to any of the skilled artisan, and various modifications and changes can be made without departing from the spirit and scope of the invention.
