Referring to fig. 5A and 5B, the actuator 66 is assembled by a vibrating plate 661 and a piezoelectric element 662, wherein the piezoelectric element 662 is attached and fixed on a surface of the vibrating plate 661. In the present embodiment, the vibrating plate 661 is made of metal, and the piezoelectric element 662 is made of piezoelectric powder of lead zirconate titanate (PZT) series with high piezoelectric number, and is attached to the vibrating plate 661, so that the piezoelectric element 662 is driven to deform by applying a voltage, and the vibrating plate 661 is driven to reciprocate vertically to deform, so as to drive the actuator 60. The vibrating plate 661 of the actuator 66 is assembled on the fourth surface 656 of the valve cavity seat 65 to cover the pressure chamber 657, and the fourth surface 656 is provided with a stepped groove 658 outside the pressure chamber 657 for receiving a sealing ring 68e therein to prevent fluid leakage around the pressure chamber 657.

As can be seen from the above description, the valve body 63, the valve diaphragm 64, the valve cavity seat 65, and the actuator 66 may constitute the main structure of the actuator 60 for guiding the fluid. However, the main subject of the present application is how to position the stacked and combined structure, and the locking and positioning assembly without using locking elements (such as screws, nuts, bolts, etc.). Therefore, the valve body 63, the valve diaphragm 64, the valve chamber seat 65, and the actuator 66 are sequentially stacked inside the outer cylinder 67 by using the design of the valve cover 62 and the outer cylinder 67, and the valve cover 62 is directly fitted inside the outer cylinder 67 to be positioned and assembled.

Referring to fig. 5A, 5B and 9, the outer tube 67 is made of metal, and has an inner wall 671 surrounding a hollow space, and a bottom of the inner wall 671 of the outer tube 67 has a protruding ring structure 672. Referring to fig. 10A and 10B, the valve cover 62 is also made of a metal material, and has a first through hole 621 and a second through hole 622 that are respectively inserted into the inlet channel 631 and the outlet channel 632 of the valve body 63, 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 tube 67.

Therefore, as shown in fig. 5A and 5B, the valve body 63, the valve diaphragm 64, the valve chamber seat 65, and the actuator 66 are sequentially stacked and then placed in the inner wall 671 of the outer tube 67, so that the entire stacked structure is supported on the collar structure 672 of the outer tube 67, and the valve cover 62 is configured to have an outer diameter slightly larger than the inner wall 671 of the outer tube 67, and can be smoothly guided into the inner wall 671 of the outer tube 67 by the chamfer 623, and the valve body 63, the valve diaphragm 64, the valve chamber seat 65, and the actuator 66 are sequentially stacked and assembled to form the actuator 60, and the actuator 66 can also be located in the hollow space of the inner wall 671 of the outer tube 67, and the piezoelectric element 662 is applied with a voltage to drive the vibrating plate 661 to reciprocate vertically and resonate, thereby achieving the purpose of locking the actuator 60 without using locking elements (such as screws, nuts, bolts, etc.) to lock the positioning assembly.

As shown in fig. 11, in the actuator 60 of the present invention, the inlet valve passage 651 of the valve chamber seat 65 is disposed corresponding to the inlet opening 6311 of the valve body 63, and the valve piece 641a of the valve diaphragm 64 is used to seal the inlet opening 6311 of the valve body 63, and the valve piece 641a is attached to the protrusion structure 6343 of the valve body 63 to generate a preload (preload) effect, which helps to generate a greater preload effect, so as to prevent the reverse flow, while the outlet valve passage 652 is disposed corresponding to the outlet opening 6321 of the valve body 63, and the valve piece 641b of the valve diaphragm 64 is used to seal the outlet valve passage 652 of the valve chamber seat 65, and the protrusion structure 6521 of the valve chamber seat 65 is attached to generate a preload (preload) effect, which helps to generate a greater preload effect, so as to prevent the reverse flow of the check pressure chamber 657, so that the actuator 60 of the present invention does not act between the inlet passage 632 and the outlet passage 632 of the valve body when the actuator is not operated.

As can be seen from the above description, when the piezoelectric element 662 of the actuator 66 is activated by applying a voltage to deform the vibrating plate 661 to be concave, the volume of the pressure chamber 657 is increased, so that a suction force is generated, the valve sheet 641a of the valve diaphragm 64 is subjected to a suction force to open rapidly, a large amount of fluid can be sucked from the inlet channel 631 of the valve body 63 and flows through the inlet opening 6311 of the valve body 63, the through hole 643a of the valve diaphragm 64, and the inlet valve channel 651 of the valve chamber seat 65 to the pressure chamber 657 for temporary storage, and the outlet valve channel 652 is also subjected to a suction force, so that the valve sheet 641b of the valve diaphragm 64 is supported by the extending support 642b to be pressed downward against the convex structure 6521 to assume a closed state.

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 deforms the vibrating plate 661 convexly, and the pressure chamber 657 contracts and decreases in volume, so that the fluid in the pressure chamber 657 is compressed, and at the same time, the interior of the inlet valve channel 651 is subjected to a thrust force, and the flap 641a of the valve diaphragm 64 is subjected to the thrust force, and supported by the extension bracket 642A, the entire upward flat contact is generated against the protrusion structure 6343, thereby presenting a closed state, and the fluid cannot flow back from the inlet valve channel 651, and at this time, the interior of the outlet valve channel 652 is also subjected to the thrust force, and the flap 641B of the valve diaphragm 64 is supported by the extension bracket 42B, thereby presenting a state that the entire upward flat contact is generated against the protrusion structure 6521, and presenting an open state, so that the fluid can flow out of the pressure chamber 657 through the outlet valve channel 652 of the outlet valve chamber seat 65, the hollow hole 643B of the valve body 63, and the outlet channel 6321 and the outlet channel 632 of the valve body 63, and thus the fluid transmission process of the fluid transmission is completed efficiently, and the fluid transmission process of the fluid transmission device can be performed continuously, and the fluid transmission process of the fluid transmission device can be performed in the present case of the present invention, and the operation process of the fluid transmission device can be implemented, and the actuation process of the actuation device can be performed continuously, and the actuation process of the fluid transmission device 60, and the present case, and the actuation process of the actuation device can be implemented.
