Referring to FIGS. 5A and 5B, the actuator 66 is assembled by a vibrating plate 661 and a piezoelectric element 662 which is attached and fixed to the surface of the vibrating plate 661. In the present embodiment, the vibrating plate 661 is made of a metal material, and the piezoelectric element 662 can be made of a piezoelectric powder of a high-voltage electric lead zirconate titanate (PZT) series, and is attached and fixed to the vibrating plate 661. The piezoelectric element 662 is driven to apply a voltage to deform, so that the vibrating plate 661 is also deformed in a vertical reciprocating motion for driving the actuating device 60. The vibrating plate 661 of the actuator 66 is disposed on the fourth surface 656 of the valve cavity seat 65 to cover the pressure chamber 657, and the fourth surface 656 is disposed outside the pressure chamber 657.

As can be seen from the above description, the valve body 63, the valve diaphragm 64, the valve body seat 65, and the actuator 66 can constitute the main structure in which the fluid guiding of the actuator 60 is introduced. However, how to position the stacked structure so that it does not need to lock the component (such as screws, nuts, bolts, etc.) to lock the positioning assembly is the main subject to be implemented in this case. Therefore, the valve body 63, the valve diaphragm 64, the valve body seat 65, and the actuator 66 are sequentially laminated inside the outer cylinder 67, and then the valve cover is used. The description is made by directly fitting and fitting the inner portion of the outer cylinder 67 to the outer cylinder 67.

Referring to FIGS. 5A, 5B, and 9 , the outer tube 67 is made of a metal material having an inner wall 671 surrounding a hollow space, and the inner wall 671 of the outer tube 67 has a convex ring structure 672 at the bottom. Referring to FIG. 10A and FIG. 10B , the valve cover body 62 is also made of a metal material, and has a first through hole 621 and a second through hole 622 respectively for the inlet passage 631 and the outlet passage of the valve body 63 . The 632 is correspondingly inserted, and the bottom edge of the valve cover 62 has a chamfer 623, and the outer diameter of the valve cover 62 is slightly larger than the inner wall 671 of the outer cylinder 67.

Therefore, as shown in FIGS. 5A and 5B, the valve body 63, the valve diaphragm 64, the valve body seat 65, and the actuator 66 are sequentially stacked and placed in the inner wall 671 of the outer cylinder 67 to allow the entire stack. Structural bearing On the convex ring structure 672 of the outer cylinder 67, the valve cover body 62 is designed to have a smaller outer diameter than the inner wall 671 of the outer cylinder 67, and can be smoothly introduced into the inner wall 671 of the outer cylinder 67 by using the chamfer 623. The snap-fit assembly is combined with the positioning valve body 63, the valve diaphragm 64, the valve body seat 65, and the actuator 66 to sequentially form the actuating device 60, and the actuator 66 can also be hollow on the inner wall 671 of the outer cylinder 67. In the space, the piezoelectric element 662 is driven to generate a voltage to drive the vibrating plate 661 to perform a vertical reciprocating motion to form a resonance, thereby achieving an actuating device 60 that does not need to lock the component (for example, a screw, a nut, a bolt, etc.) to lock the positioning assembly. .

As shown in Fig. 11, in the case of the actuator device 60, the inlet valve passage 651 of the valve body seat 65 is disposed corresponding to the inlet opening 6311 of the valve body 63, and is closed by the valve piece 641a of the valve diaphragm 64. The function of the valve structure is performed, and the valve piece 641a covers the inlet opening 6311 of the valve body 63, and at the same time, the convex portion structure 6343 of the valve body 63 is attached to generate a pre-force effect, which helps to produce a larger pre-cover. The tightening effect is to prevent backflow, and the outlet valve passage 652 is disposed corresponding to the outlet opening 6321 of the valve body 63, and is closed by the valve piece 641b of the valve diaphragm 64 to function as a valve structure, and the valve of the valve diaphragm 64 The piece 641b covers the outlet valve passage 652 of the valve cavity seat 65, and simultaneously engages the convex portion structure 6521 of the valve cavity seat 65 to generate a pre-force effect, which contributes to a larger pre-tightening effect. In order to prevent the back pressure chamber 657 from being pressed into the pressure chamber 657, the actuating device 60 constructed in the present case does not produce a backflow between the inlet passage 631 and the outlet passage 632 of the valve body 63 without being actuated.

As can be seen from the above description, the actuating device 60 of the present invention performs the fluid transfer operation as shown in FIG. 12A. When the piezoelectric element 662 of the actuator 66 is actuated by the application of a voltage, the vibrating plate 661 is concavely deformed. When the volume of the pressure chamber 657 is increased, suction is generated, and the valve piece 641a of the valve diaphragm 64 is quickly opened by a suction force, so that the fluid can be sucked in a large amount from the inlet passage 631 on the valve body 63, and flows through The inlet opening 6311 of the valve body 63, the hollow hole 643a of the valve diaphragm 64, and the inlet valve passage 651 of the valve cavity seat 65 flow into the pressure chamber 657 Temporarily stored, while the outlet valve passage 652 is also subjected to suction, the valve piece 641b of the valve diaphragm 64 is subjected to the suction force, and the entire downwardly flat contact against the convex portion structure 6521 is brought into a closed state by the support of the extension bracket 642b.

Thereafter, as shown in FIG. 12B, when the direction of the electric field applied to the piezoelectric element 662 is changed, the piezoelectric element 662 will cause the vibration plate 661 to be convexly deformed, and at this time, the pressure chamber 657 contracts and the volume is reduced to make the pressure chamber. The fluid in the chamber 657 is squeezed, and at the same time, the inlet valve passage 651 is subjected to the thrust, and the valve piece 641a of the valve diaphragm 64 is subjected to the thrust, and the support is extended by the extension bracket 642a to produce the entire upward flatness against the convex structure. 6343 is in a closed state, the fluid cannot be reversed by the inlet valve passage 651, and at this time, the outlet valve passage 652 is also subjected to thrust, and the valve piece 641b of the valve diaphragm 64 is subjected to the thrust, and the entire support is generated by the support of the extension bracket 42b. The detachment is in a state of being close to the convex portion structure 6521, and the fluid is discharged from the outlet valve passage 652 out of the pressure chamber 657 via the outlet valve passage 652 of the valve cavity seat 65 and the valve diaphragm 64. The hollow hole 643b, the outlet opening 6321 on the valve body 63, and the outlet passage 632 flow out of the actuating device 60, so the process of fluid transfer is completed, and the operations of FIGS. 12A and 12B are repeated, that is, the operation is continued. The delivery of the fluid, such as the actuating device 60 of the present invention, allows the fluid to be reflowed during transport without the need for recirculation to achieve efficient transmission.

When the result of the test liquid in the first container is normal, the sensor 20 stops the actuating device 60 for the user to use the test liquid that has been filtered and passed the detection in the first container 10.

Referring to FIG. 13 , which is another embodiment of the portable liquid detecting and filtering device 1 of the present invention, the portable liquid detecting and filtering device 1 further includes a second container 40 disposed on the second container 40 . Under the bottom of the first container 10, the first container 10 further includes a filtering channel 12 connecting the actuating device 60 and the filter element 30, and communicating with the second container 40, the remaining components and the upper An embodiment is the same, so it will not be described; when the sensor 20 detects that the detection result of the detection liquid in the first container 10 is abnormal, the sensor 20 activates the actuation device 60, and the actuation device 60 starts to capture the first The detection liquid in a container, and the detection liquid is delivered to the filter element 30, through which the detection liquid is filtered to enter the second container 40, so as to be filtered. The test liquid is contained in the second container 40.
