It should be understood that this case can have various changes in different aspects without departing from the scope of this case, and that the descriptions and diagrams therein are used as illustrations in nature, not to limit this case.

Please refer to Fig. 1, which is a schematic structural view of the pump in the first preferred embodiment of the present case. As shown in the figure, the pump 1 of this case is mainly composed of a micropump device 10 and a filter joint 11, wherein the micropump device 10 has an inlet 100 and an outlet 101, and in the micropump device 10, for example, an actuator ( not shown), inlet/outlet valve structure (not shown), but not limited thereto. The control structure (not shown) flows in the chamber (not shown) of the micropump device 10 , and then flows out through the outlet 101 . In some embodiments, the inlet 100 and the outlet 101 are respectively connected to the communication pipes 102 and 103 for assisting the delivery of the fluid.

Please continue to refer to FIG. 1, as shown in the figure, the filter joint 11 of this case is detachably connected to the inlet 100 of the micropump device 10, and the filter joint 11 is mainly composed of a hollow body 110 and an insertion port 114 communicating with the hollow body 100. , the first opening 111 and the filter screen 113, but not limited thereto. As shown in FIG. 1 and FIG. 2 , in this embodiment, the hollow body 110 can be, but not limited to, a frame structure in which there is an accommodating space 115 , and the hollow body 110 has a first surface 110 a and a side surface 116 , the first opening 111 is disposed on the first surface 110a. And, in this embodiment, the socket 114 can be but not limited to a hollow tubular structure, and protrudingly arranged on the side 116 of the hollow body 110, because the socket 114 is connected with the accommodation space inside the hollow body 110 115 is connected, so it can transport the fluid in the accommodating space 115 to the inlet 100 of the micropump device 10 connected to the other end through the plug port 114. In this embodiment, one end of the plug port 114 is connected to the The connecting pipe 102 is connected, and can be connected with the inlet 100 of the micropump device 10 through the connecting pipe 102, but in other embodiments, the insertion port 114 can also be directly connected with the inlet 100 of the micropump device 10, Its implementation is not limited thereto. In addition, in some embodiments, the insertion interface 114 can be but not limited to a structure integrally formed with the hollow body 110, and in other embodiments, the insertion interface 114 can also be set as a detachable structure, and can be It is installed separately from the hollow body 110 , and its shape and connection method can be changed freely according to the actual implementation situation, and are not limited thereto.

In this embodiment, the mesh size of the filter screen 113 is preferably between 100 mesh and 500 mesh, and the mesh size of 300 mesh is the best, but it is not limited thereto. The effect of the pore size on the performance of the pump 1 about the mesh number of the filter screen 113 is shown in Table 1 below:

Table I

As shown in Table 1, the control group is a pump without a filter joint. It can be seen from the table that although the filter screen will produce a certain resistance to the fluid after the filter joint is used, it can be obtained from the experimental data in Table 1. It is known that although filter screens with different mesh numbers (that is, corresponding to different pore sizes) are used, they do not have a particularly large impact on the flow rate and lift of the pump, so it can be seen that even the pump with the filter joint of this case can still be used. Maintain its fluid delivery performance, and at the same time, it can filter the fluid to remove impurities that will affect the performance and service life of the pump.

In addition, in some embodiments, the filter screen 113 can be covered and bonded to the first opening 111 of the first surface 110a by welding, but the combination of the filter screen 113 and the first opening 111 is not limited thereto. It can also adopt other joining methods according to the actual implementation situation.

Please continue to refer to Fig. 1, as shown in the figure, the filter joint 11 of the pump 1 can be arranged in other devices 2 containing fluid, but it is not limited thereto, when the pump 1 is activated, the filter joint 11 can pass through the micropump device 10 suction force, and impels the fluid to flow into the accommodation space 115 of the hollow body 110 of the filter joint 11 from the filter screen 113 on the first opening 111 of the filter joint 11, and then flows into the connecting pipe 102 through the socket 114, and flows to the inlet 100 of the micropump device 10, then enters the micropump device 10, and finally flows out from the outlet 101 of the micropump device 10, whereby the pump 1 of this case can pass through the filter joint 11 to effectively filter fluid impurities , and will not affect the purpose of the operation of the micropump device 10 .

Please refer to Figure 3, Figure 4A and Figure 4B at the same time, Figure 3 is a schematic diagram of the separation of the filter screen of the pump in the second preferred embodiment of the case, and Figure 4A is a schematic structural view of the filter joint of the pump in the second preferred embodiment of the case , Fig. 4B is a side view of Fig. 4A. As shown in Figure 3, the pump 2 of this case has a micropump structure 20 and a filter joint 21 equally, and the micropump structure 20 also has an inlet 200, an outlet 201, and connecting pipes 202, 202, and 203. Similarly, the filter joint 21 also has a hollow body 210 , an insertion port 214 communicating with the hollow body 210 , and a first opening 211 . However, in this embodiment, the filter joint 21 of the pump 2 further has a second opening 217 (as shown in FIG. The surface 210b is disposed corresponding to the first surface 210a.

And, in this embodiment, the filter joint 21 further includes another filter screen 218, which is correspondingly covered and arranged on the second opening 217, and as mentioned above, the filter screen 218 can be welded and correspondingly arranged on the second opening 217. On the second opening 217 of the second surface 210b, but not limited thereto. As for the mesh number of the filter screen 218, it is also preferably between 100 mesh and 500 mesh, and 300 mesh is the best, but it is not limited thereto.

And in this embodiment, the first opening 211 and the second opening 217 are large-area openings, but it is not limited to this, and because this embodiment has the first opening 211 and the second opening 217 at the same time, so multi-directional Moreover, the large-area opening and the corresponding filter mesh design can reduce the fluid resistance generated when filtering fluid.

Please refer to Fig. 3 and Fig. 5 at the same time. Fig. 5 is a schematic diagram of the operation of the pump shown in Fig. 3. As shown in the figure, in this embodiment, the filter joint 11 of the pump 2 can be arranged on other devices containing fluid , but not limited thereto, when the pump 2 is activated, the suction force of the micropump device 20 can cause the fluid to flow from the first opening 211 of the filter joint 21 as shown in the arrow direction in the figure and the filter screens 213, 218 on the second opening 217 flow into the accommodation space 215 of the hollow body 210 of the filter joint 21, then flow into the connecting pipe 202 through the socket 214, and then flow to the inlet 200 of the micropump device 20, and into the micropump device 20, and finally flows out through the outlet 201 of the micropump device 20. In this embodiment, by correspondingly covering and welding the two filter screens 213 and 218 on the two open ends (ie, the first opening 211 and the second opening 217) of the filter joint 21, it is effective for other devices. In this way, through the setting of the filter joint 21 of the pump 2, it is not necessary to separately set up related filter devices in the fluid tanks of other devices.
