Referring to fig. 3A and 3B, fig. 3A is a schematic structural view of a flow guiding unit of the present disclosure, and fig. 3B is a schematic structural view of an actuating element of the present disclosure. The flow guiding units 241 respectively include a base 2411, an inlet plate 2412, a resonance plate 2413, a spacer 2414, an actuating member 2415 and an outlet member 2416, wherein the base 2411 is provided with an inlet 2411 a. The inlet plate 2412 is provided on one side (hereinafter, not limited to) of the base 2411, and the inlet plate 2412 has at least one inlet 2412a, and the inlet 2412a communicates with the inlet 2412a of the base 2411. The resonator plate 2413 is disposed on the other side (e.g., above, but not limited to) of the base 2411, and is spaced from the inlet plate 2412, the resonator plate 2413 has a center hole 2413a, a movable portion 2413b, and a fixed portion 2413c, the center hole 2413a is located at the center of the resonator plate 2413 and vertically corresponds to the inlet hole 2411a of the base 2411, the movable portion 2413b is located at the periphery of the center hole 2413a and corresponds to the inlet 2412a, so that the movable portion 2413b can vertically vibrate at the position of the inlet hole 2411a, and the fixed portion 2413c is located at the periphery of the resonator plate 2413 and is fixed to the base 2411. The spacer 2414 is disposed on the fixing portion 2413c of the resonator plate 2413, and its central region is recessed to define a spacing chamber 2414a with the resonator plate 2413. The actuator 2415 is disposed on the spacer 2414, and has a vibration portion 2415a, an outer frame portion 2415b, a plurality of connection portions 2415c, a plurality of gaps 2415d and a piezoelectric element 2415e, wherein the vibration portion 2415a is disposed at the center of the actuator 2415 and vertically corresponds to the spacing chamber 2414a, the connection portions 2415c are disposed between the vibration portion 2415a and the outer frame portion 2415b, connect the two and elastically support the vibration portion 2415a, the gaps 2415d are formed between the vibration portion 2415a, the outer frame portion 2415b and the connection portions 2415c, and allow fluid to pass therethrough, and the piezoelectric element 2415e is attached to the vibration portion 2415 a; the outlet member 2416 has a frame plate 2416a and a cover plate 2416b, the frame plate 2416a is overlapped on the outer frame portion 2415b of the actuating member 2415, and the central recess thereof and the vibrating portion 2415a of the actuating member 2415 define an outlet chamber 2416c, the cover plate 2416b is overlapped on the frame plate 2416a and has an outlet 2416d at the center thereof; the piezoelectric element 2415e begins to deform due to the piezoelectric effect, and thus the vibrating portion 2415a of the actuator 2415 attached thereto is driven to vibrate up and down between the outlet chamber 2416c and the spacing chamber 2414a, thereby changing the volumes of the outlet chamber 2416c and the spacing chamber 2414a to change the internal pressure of the two chambers, thereby generating a pressure gradient, and facilitating the fluid to enter from the inlet 2412a, pass through the inlet 2411a, the central hole 2413a, the gap 2415d, and finally be discharged from the outlet 2416d to deliver the fluid.

Please refer to fig. 3C to fig. 3D, wherein fig. 3C and fig. 3D are schematic operation diagrams of the flow guide unit according to the present disclosure. When the piezoelectric element 2415e drives the actuating element 2415 by the piezoelectric effect, referring to fig. 3C, the piezoelectric element 2415e leads the vibrating portion 2415a of the actuating element 2415 to displace upward, and synchronously drives the movable portion 2413b of the resonator plate 2413 to displace upward by the resonance effect, so that the vibrating portion 2415a moves toward the outlet member 2416, which will greatly increase the volume of the partition chamber 2414a, and start to draw the fluid in the inlet port 2412a into the partition chamber 2414a, and at the same time, as the movable portion 2413b of the resonator plate 2413 moves upward, the volume in the inlet port 2411a of the base 2411 is increased, and the fluid added to the inlet port 2411a starts to be introduced into the partition chamber 2414a, so that the inlet port 2411a is also in a negative pressure state, and a large amount of fluid outside the flow guide unit 241 is drawn through the inlet port 2412a of the inlet plate 2412 into the flow guide port 2411 a. Referring again to fig. 3D, the piezoelectric element 2415e guides the downward displacement of the vibrating portion 2415a of the actuating member 2415. And the movable part 2413b of the resonance plate 2413 is displaced downward in synchronization with the resonance effect, and when the vibrating part 2415a is displaced downward, the fluid pressing the partition chamber 2414a starts to rapidly flow to the outlet chamber 2416c, the pressure of the outlet chamber 2416c is rapidly increased, and the fluid starts to be discharged from the outlet port 2416 d. At the same time, since the fluid in the partition chamber 2414a and the outlet chamber 2416c is rapidly discharged to the outlet 2416d, the interior of the partition chamber 2414a and the outlet chamber 2416c is in a negative pressure state, and the fluid is continuously introduced from the inlet 2412 a. Repeating the above steps will allow fluid to continuously enter the inlet 2412a, pass through the inlet aperture 2411a, the central bore 2413a, the separation chamber 2414a, the void 2415d, the outlet chamber 2416c, and finally exit the outlet 2416d for delivery of the fluid.

When the flow guiding units 241 are arranged in series, two flow guiding units 241 are vertically spaced and fixed by a fixing structure 245, a series chamber 2451 is defined between the flow guiding units 241 in series, and the fixing structure 245 is provided with a series outlet 2452, so that the flow guiding units 241 in series can guide the fluid to the series chamber 2451, and then concentrate on the series outlet 2452 and discharge the fluid.

Referring to fig. 4C, fig. 4C is a schematic diagram of the flow guiding units connected in series and in parallel. The plurality of flow guiding units 241 may be arranged in series and parallel to form a driving region 241A, and fig. 4C illustrates four flow guiding units 241, but not limited thereto. The series-parallel connection mode is that the flow guide units 241 are arranged in parallel, then the flow guide units 241 after being connected in parallel are connected in series through the fixing structure 245, so that the flow guide units 241 after being connected in series and in parallel can concentrate the fluid in the series chamber 2451 before the fluid is discharged through the series outlet 2452.

Referring to fig. 5A, fig. 5A is a schematic structural diagram of a first embodiment of a valve of a power driver of the present disclosure. The valves 243 each include a passage base 2431, a first passage 2432, a second passage 2433, an actuating plate 2434, a piezoelectric plate 2435, and a closing member 2436, wherein the passage base 2431 has a base surface 2431a and is recessed from the base surface 2431a to form a valve chamber 2431 b. The first passage 2432 is located in the passage base 2431, and one end of the first passage 2432 serves as a flow inlet 2432a for connecting the driving region 241A, and the other end communicates with the valve chamber 2431 b. The second passage 2433 is also located in the passage base 2431 and has a communication area 2433a and an exit area 2433b, the communication area 2433a and the exit area 2433b are perpendicular to each other and communicate with each other, the communication area 2433a is located between the exit area 2433b and the valve chamber 2431b, one end of the communication area is communicated with the exit area 2433b, and the other end of the communication area is communicated with the valve chamber 2431b, so that the exit area 2433b is communicated with the valve chamber 2431 b. The actuating plate 2434 is disposed on the base surface 2431a and covers the valve chamber 2431b, and the actuating plate 2434 has a first actuating surface 2434a and a second actuating surface 2434 b. The piezoelectric plate 2435 is attached to the first actuating surface 2434a of the actuating plate 2434. The closing member 2436 has a blocking portion 2436a and a connecting rod 2436b, the connecting rod 2436b is inserted into the communicating area 2433a of the second passage 2433, and has one end connected to the blocking portion 2436a and the other end connected to the second actuating surface 2434b of the actuating plate 2434; wherein the cross-sectional area of the obstruction 2436a is greater than the cross-sectional area of the second passage 2433 at the communicating area 2433a thereof, and the length of the link 2436b is greater than the length of the second passage 2433 at the communicating area 2433a thereof.

As mentioned above, when the piezoelectric plate 2435 is not actuated, the valve 243 is in an open state (as shown in fig. 5A), and since the length of the connecting rod 2436b is greater than the sum of the length of the communicating area 2433a and the depth of the valve chamber 2431b, when the movable plate 2434 is horizontal, the blocking portion 2436a will not close the position of the second passage 2433 where the communicating area 2433a and the outlet area 2433b are connected, so that the communicating area 2433a and the outlet area 2433b are communicated with each other, and fluid can enter from the fluid inlet 2432a of the first passage 2432, flow into the valve chamber 2431b, and finally flow out through the communicating area 2433a and the outlet area 2433 b. Referring to fig. 5B, fig. 5B is a schematic closing diagram of the valve of the power driver of the present disclosure. When the piezoelectric plate 2435 deforms and drives the actuating plate 2434 to bend away from the channel base 2431 through stress, the link 2436b of the closing member 2436 is pulled up, so that the blocking portion 2436a of the closing member 2436 abuts against a position in the second channel 2433 where the communicating area 2433a and the outlet area 2433b are connected, the communicating area 2433a is closed, the valve 243 is closed, and the opening or closing of the valve 243 is controlled through the piezoelectric plate 2435, so as to further control the flow rate and the pressure of the fluid flowing into the confluence chamber 244.

Referring to fig. 6A, fig. 6A is a schematic structural diagram of a second embodiment of a valve of a power driver of the present disclosure. The structure is substantially the same as that of the previous embodiment, and therefore will not be described again, but the difference is that the length of the connecting rod 2436b in this embodiment is equal to the sum of the length of the communicating area 2433a and the depth of the valve chamber 2431b, so that when the piezoelectric sheet 2435 is not actuated, the blocking portion 2436a abuts against the communicating area 2433a and the outlet area 2433b, so as to block the communicating area 2433a and the outlet area 2433b, and fluid cannot pass through, so that the valve 243 is in a closed state, and thus the valve 243 in this embodiment is in a normally closed state. Referring to fig. 6B, when the piezoelectric plate 2435 deforms and the actuating plate 2434 is driven to bend in a direction approaching the channel base 2431 by stress, the connecting rod 2436B of the closing member 2436 is pushed, so that the blocking portion 2436a of the closing member 2436 is away from the position of the second channel 2433 where the communicating area 2433a and the outlet area 2433B are connected, so that the communicating area 2433a and the outlet area 2433B are communicated, and the valve 243 is opened. In this embodiment, the piezoelectric sheet 2435 is used to control the opening or closing of the valve 243 to further control the flow rate and pressure of the fluid flowing into the confluence chamber 244.
