Please refer to Figures 3A and 3B first. Figure 3A is a schematic diagram of the structure of the diversion unit of the project, and Figure 3B is a schematic diagram of the structure of the actuator of the project. The guide units 241 respectively include a base 2411, an inlet plate 2412, a resonance plate 2413, a spacer 2414, an actuator 2415, and an outlet member 2416. The base 2411 is provided with an inflow hole 2411a. The inlet plate 2412 is disposed on one side of the base 2411 (the following is not a limitation), and the inlet plate 2412 has at least a flow inlet 2412a, and the inlet 2412a communicates with the inlet 2412a of the base 2411. The resonance plate 2413 is arranged on the other side of the base 2411 (the upper part is not limited to this), and is arranged opposite to the entrance plate 2412. The resonance plate 2413 has a central hole 2413a, a movable part 2413b, and a fixed part 2413c . The central perforation 2413a is located at the center of the resonance plate 2413 and corresponds perpendicularly to the inflow hole 2411a of the base 2411, and the movable portion 2413b is located on the periphery of the central perforation 2413a and corresponds to the inflow port 2412a, so that the movable portion 2413b can be in the inflow hole 2411a. The position oscillates up and down, and the fixing portion 2413c is located in the peripheral area of the resonance plate 2413 for fixing to the base 2411. The spacer 2414 is disposed on the fixing portion 2413c of the resonance plate 2413, and the central area of the spacer 2414 is recessed with the resonance plate 2413 to define a compartment 2414a. The actuating member 2415 is disposed on the spacer 2414, and has a vibrating portion 2415a, an outer frame portion 2415b, a plurality of connecting portions 2415c, a plurality of gaps 2415d, and a piezoelectric member 2415e. The vibrating portion 2415a is located in the center of the actuating member 2415 , And perpendicular to the compartment 2414a, the connecting portions 2415c are provided between the vibrating portion 2415a and the outer frame portion 2415b, connecting the two and elastically supporting the vibrating portion 2415a, and these gaps 2415d are formed in the vibrating portion 2415a and the outer frame Between the part 2415b and the connecting parts 2415c, fluid passes through, and the piezoelectric element 2415e is attached to the vibrating part 2415a. The outlet member 2416 has a frame plate 2416a and a cover plate 2416b. The frame plate 2416a is stacked on the outer frame portion 2415b of the actuating member 2415, and its central recess and the vibrating portion 2415a of the actuating member 2415 define an outlet cavity 2416c, The cover plate 2416b is stacked on the frame plate 2416a and has a first-rate outlet 2416d in the center; among them, the piezoelectric element 2415e begins to deform due to the piezoelectric effect, so it drives the vibrating part 2415a of the actuator 2415 attached to it in the outlet chamber 2416c Vibrate up and down with the compartment 2414a, thereby changing the volume of the outlet chamber 2416c and the compartment 2414a, changing the pressure inside the two, thereby generating a pressure gradient, and encouraging fluid to enter through the inlet 2412a and through the inflow hole 2411a , The central perforation 2413a, the gap 2415d, and finally discharged from the outlet 2416d to transport fluid.

Please continue to refer to Figures 3C to 3D. Figures 3C and 3D are schematic diagrams of the operation of the diversion unit of this project. When the piezoelectric element 2415e uses the piezoelectric effect to drive the actuator 2415, please refer to Figure 3C first. The piezoelectric element 2415e leads the vibrating part 2415a of the actuator 2415 to move upward, and uses the resonance effect to synchronously drive the resonance plate 2413. The movable portion 2413b is displaced upward. As the vibrating part 2415a moves toward the outlet member 2416, the volume of the compartment 2414a will be greatly increased, and the fluid in the inlet 2412a will be sucked into the compartment 2414a. At the same time, the movable part 2413b of the resonance plate 2413 will move upwards. The volume of the inflow hole 2411a of the base 2411 is increased, and the fluid in the inflow hole 2411a is introduced into the compartment 2414a, so that the inflow hole 2411a is also in a negative pressure state, and the flow is drawn and guided through the inflow port 2412a of the inlet plate 2412 A large amount of fluid outside the unit 241 enters the inflow hole 2411a. Referring again to FIG. 3D, the piezoelectric element 2415e causes the vibrating part 2415a of the moving element 2415 to move downward, and synchronously links the movable part 2413b of the resonance plate 2413 to move downward through the resonance effect. When the vibrating portion 2415a is displaced downward, the fluid that begins to squeeze the compartment 2414a flows rapidly to the outlet cavity 2416c, the pressure of the outlet cavity 2416c increases sharply, and the fluid starts to be discharged from the outlet 2416d. At the same time, since the fluid in the compartment 2414a and the outlet chamber 2416c is rapidly discharged to the outflow port 2416d, the compartment 2414a and the outlet chamber 2416c present a negative pressure state, so that the fluid continuously enters through the inflow port 2412a. Repeating the above two steps in this way will enable the fluid to continuously enter from the inlet 2412a, through the inflow hole 2411a, the central perforation 2413a, the compartment 2414a, the gap 2415d, the outlet chamber 2416c, and finally the outflow port 2416d for transportation fluid.

Please refer to Figure 4A. Figure 4A is a schematic diagram of the parallel connection of diversion units in this case. The guiding units 241 in this case can be arranged in parallel to form the driving area 241A. In FIG. 4A, two guide units 241 are used for illustration, but not limited thereto. When the guide units 241 are arranged in parallel, the adjacent guide units 241 can share the same base 2411, the inlet plate 2412, the resonance plate 2413, the spacer 2414, the actuator 2415, and the outlet member 2416, and they can be used separately Different areas of each element complete the related structure. When the base 2411, the inlet plate 2412, the resonance plate 2413, the spacer 2414, the actuator 2415, and the outlet member 2416 are stacked, multiple flow guide units 241 arranged in parallel can be completed.

Please refer to Figure 4B. Figure 4B is a schematic diagram of the series connection of the diversion units in this project. The diversion units 241 in this case can be arranged in series to form a driving area 241A. FIG. 4B uses two diversion units 241 for illustration, but is not limited to this. When the diversion units 241 are arranged in series, the two diversion units 241 are vertically spaced and fixed through a fixed structure 245. The series-connected diversion units 241 define a series chamber 2451, and the fixed structure 245 A series outlet 2452 is provided, so that the series-connected flow guiding unit 241 can guide the fluid to the series-connected chamber 2451, and then concentrate on the series-connected outlet 2452 to discharge the fluid together.

Please refer to Figure 4C. Figure 4C is a schematic diagram of the series and parallel connection of the diversion units in this case. In this case, the guide units 241 can be arranged in series and parallel to form a driving area 241A. FIG. 4C uses four guide units 241 for illustration, but is not limited to this. The series-parallel method is to first arrange the guide units 241 in parallel, and then connect the parallel guide units 241 in series through the fixed structure 245, so that the series-parallel guide units 241 can precede the fluids in the series chamber 2451 Concentrated, and finally eliminated by the serial exit 2452.

Please refer to Fig. 5A first. Fig. 5A is a structural diagram of the first embodiment of the valve of the power actuator of the present invention. The valves 243 in this case all include a channel base 2431, a first channel 2432, a second channel 2433, an actuating piece 2434, a piezoelectric piece 2435, and a closing member 2436, respectively. The channel base 2431 has a base surface 2431a, and is recessed on the base surface 2431a to form a valve chamber 2431b. The first channel 2432 is located in the channel base 2431. One end of the first channel 2432 serves as an inlet 2432a for connecting the driving area 241A, and the other end is connected to the valve chamber 2431b. The second passage 2433 is also located in the passage base 2431, and has a communication area 2433a and an outlet area 2433b. The communication area 2433a and the outlet area 2433b are perpendicular to and communicate with each other. The communication area 2433a is located between the outlet area 2433b and the valve chamber 2431b. In the meantime, one end is connected to the outlet area 2433b, and the other end is connected to the valve chamber 2431b, so that the outlet area 2433b communicates with the valve chamber 2431b. The actuating piece 2434 is disposed on the base surface 2431a and covers the valve chamber 2431b. The actuating piece 2434 has a first actuating surface 2434a and a second actuating surface 2434b. The piezoelectric sheet 2435 is attached to the first actuation surface 2434a of the actuation sheet 2434. The closing member 2436 has a blocking portion 2436a and a connecting rod 2436b. The connecting rod 2436b penetrates through the communication area 2433a of the second channel 2433, one end of which is connected to the blocking portion 2436a, and the other end is connected to the second actuating surface 2434b of the actuating piece 2434; The cross-sectional area of the blocking portion 2436a is greater than the cross-sectional area of the second passage 2433 and the communication area 2433a, and the length of the connecting rod 2436b is greater than the length of the second passage 2433 and the communication area 2433a.

As mentioned above, when the piezoelectric disc 2435 has not actuated, the valve 243 is in the open state (as shown in Fig. 5A). Since the length of the connecting rod 2436b is greater than the sum of the length of the communication area 2433a and the depth of the valve chamber 2431b, it serves as a moving disc. When 2434 is in a horizontal shape, the blocking portion 2436a will not close the position where the connecting area 2433a and the outlet area 2433b of the second channel 2433 are connected, so that the connecting area 2433a and the outlet area 2433b are in communication with each other, and fluid can flow in from the first channel 2432. The port 2432a enters, flows into the valve chamber 2431b, and finally flows out through the communication area 2433a and the outlet area 2433b. Please refer to Figure 5B again. Figure 5B is a schematic diagram of the closed valve of the power actuator of this case. When the piezoelectric sheet 2435 is deformed and the moving sheet 2434 is bent away from the channel base 2431 through the stress, the connecting rod 2436b of the closure 2436 is pulled up, so that the blocking portion 2436a of the closure 2436 abuts against the second channel 2433 The position where the middle communication area 2433a and the outlet area 2433b are connected, the communication area 2433a is closed to close the valve 243, and the opening or closing of the valve is controlled through the piezoelectric sheet 2435 to further control the flow and pressure of the fluid flowing into the confluence chamber 244 .

Please refer to Fig. 6A. Fig. 6A is a schematic structural diagram of the second embodiment of the valve of the power actuator in this case. Its structure is roughly the same as the previous embodiment, so it will not be repeated. 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 when the piezoelectric piece 2435 has not actuated , The blocking portion 2436a is tightly connected to the communicating area 2433a and the outlet area 2433b, blocking the communicating area 2433a and the outlet area 2433b, fluid cannot pass, and the valve 243 is closed. Therefore, the valve 243 of this embodiment is normally closed. status. Referring again to Figure 6B, when the piezoelectric sheet 2435 is deformed and the moving sheet 2434 is bent toward the channel base 2431 through the stress, the connecting rod 2436b of the closing member 2436 is pushed at the same time, so that the blocking portion 2436a of the closing member 2436 leaves the first The connecting position of the connecting area 2433a and the outlet area 2433b in the two passages 2433 makes the connecting area 2433a communicate with the outlet area 2433b, so that the valve 243 is opened. This embodiment, like the first embodiment, uses the piezoelectric sheet 2435 to control the opening or closing of the valve 243 to further control the flow and pressure of the fluid flowing into the confluence chamber 244.

In summary, this project provides a miniature detection device that uses a power driver composed of multiple diversion units with diversion channels, valves, and confluence chambers, and uses the thrust generated by the transmission fluid to propel the flying vehicle to make the flight The vehicle can be moved by thrust, and the detection unit provided on the flight vehicle provides relevant detection signals, which are transmitted back to the controller on the user side. The power driver of the guide unit can reduce the volume, Weight reduction is more advantageous for flying vehicles and has great industrial use value, so an application is filed in accordance with the law.

This case can be modified in many ways by those who are familiar with this technology, but it is not deviated from the protection of the patent application.
