To meet the requirement of the prior fluid action device for expanding the total input amount of the fluid and enrich the flow expanding mode or path of the fluid action device. Fig. 4 is a schematic structural diagram of a first embodiment of a middle-flow negative-pressure amplification structure of a fluid action device according to the present invention, and as shown in fig. 4, a middle-flow negative-pressure amplification structure 420 provided in the first embodiment of the middle-flow negative-pressure amplification structure includes a fluid cylinder 421; the body of the fluid cylinder 421 is provided with a middle fluid secondary inlet 422, and the middle fluid secondary inlet 422 is communicated with the inner space of the fluid cylinder 421.
Further, the middle section fluid secondary inlet 422 forms an annular opening at the sidewall of the fluid cylinder 421; the middle section fluid auxiliary inlet 422 with annular belt-shaped opening establishes a narrow passage at the part of the inner side of the fluid cylinder 421, which is actually communicated with the inside of the fluid cylinder 421; the narrow passage is positioned at the tail part of the outlet end of the flow guide structure body or behind the outlet end of the flow guide structure body.
Further, as shown in fig. 5-7, the middle-stage flow rate negative pressure amplification structure 420 further includes an bucket 423, and the bucket 423 is disposed outside the middle-stage flow secondary inlet 422; the opening of the bucket 423 is a driven fluid amplification inlet; when the fast flowing internal fluid flows through the middle section fluid secondary inlet 422, negative pressure (lower than the pressure of the external fluid) is generated at the position, namely, a pressure difference is formed between the inside and the outside of the middle section fluid secondary inlet 422, and under the action of the pressure difference, the external fluid of the middle section fluid secondary inlet 422 is forced to enter the inside of the middle section fluid secondary inlet 422, so that the purpose of fluid input amplification is realized.
Further, the bucket 423 may be formed integrally with the fluid cylinder 421, or may be formed integrally with the fluid cylinder 421.
In particular, as shown in FIGS. 5-7, the bucket 423 may be tapered, curved, or folded.
In particular, as shown in fig. 4, the middle flow guide strip 424 may be disposed at the middle fluid secondary inlet 422, and as shown in fig. 5-7, the middle flow guide strip 424 may also be disposed in the bucket 423.
Further, the middle guide strip 424 disposed at the annular opening separates the fluid cylinder 421 into two separated parts to be connected into a whole, but not enough to affect the amplification fluid input too much.
Further, the middle-section flow-guiding strips 424 may also be arranged as flow-guiding strips, i.e. flow-guiding strips in spoke shape perpendicular to the axis of the fluid cylinder 421, and the two separated parts of the fluid cylinder 421 are connected into an integral structure by the middle-section flow-guiding strips 424.
It should be noted that the middle-section diversion strip has a function of connecting two parts separated by the annular-belt-shaped opening to form an integral structure, and the structure of the guided middle-section amplification input fluid is changed into a structure with pre-rotation (left or right) or without pre-rotation (linear input) by selectively arranging the structure of the middle-section diversion strip.
By designing different structures of the middle flow guide strip 424, the fluid can enter in a pre-rotation or non-pre-rotation mode, and the following description lists several structures:
in specific implementation, as shown in fig. 5 to 7, the middle-section flow guide strips 424 are arranged in a left-handed manner, and when fluid passes through the secondary inlets between the middle-section flow guide strips 424, the direction of the fluid is changed according to the arrangement structure of the middle-section flow guide strips 424, so that the external fluid rotates in a left-handed manner to enter the fluid cylinder 421.
In specific implementation, as shown in fig. 4, the middle-section flow guide strips 424 are in a planar structure and are radially arranged around the central axis, and when fluid passes through the secondary inlets between the middle-section flow guide strips 424, the direction of the fluid is changed according to the arrangement structure of the middle-section flow guide strips 424, so that the fluid enters the fluid cylinder 421 in a linear manner, and the fluid has no pre-rotation effect.
In order to meet the actual requirement of a high dynamic pressure (or high total pressure) of fluid output by a fluid action device, or the requirement of a use scene that a dynamic-static pressure conversion structure or a device arranged by the fluid action device obtains high static pressure of the output fluid, the invention provides a fluid centrifugal cross-flow action device with a fluid pressurization output structural body, fig. 12 is a structural schematic diagram of a first embodiment of the fluid centrifugal cross-flow action device with the fluid pressurization output structural body, and as shown in fig. 12, the fluid centrifugal cross-flow action device provided by the first embodiment of the fluid centrifugal cross-flow action device with the fluid pressurization output structural body comprises a centrifugal impeller 100, a centrifugal cross-flow guide cylinder 200 and a fluid pressurization output structural body 600; the fluid pressurization output structure 600 is an impeller for increasing the dynamic pressure of the output fluid; the fluid pressurization output structure 600 is deployed within the centrifugal flow-through diversion cylinder 200, with the fluid pressurization output structure 600 located behind the fluid outflow end of the diversion structure.
When the centrifugal cross-flow guide cylinder is used, high-speed fluid which is input by a centrifugal impeller and flows out from the output end of the centrifugal cross-flow guide cylinder 200 through the guide structure body is subjected to work again by the fluid pressurization output structure body 600, so that the output fluid dynamic pressure of the centrifugal cross-flow action device is further improved.
In particular, as shown in fig. 13-14, the fluid pressurization output structure 600 may be selected from an axial flow impeller, a conical impeller, and a structure in which the movable impeller 611 is matched with the stationary vane body 612. It should be noted that the fluid pressurization output structure 600 is not limited to the structure using the axial flow impeller, the tapered impeller, and the structure using the movable impeller and the stationary blade in cooperation, and any other pressurization impeller structure designed to increase the fluid output pressure also belongs to the inventive concept of the present invention, and falls within the protective scope of the present invention.

Alternatively, a single total shaft arrangement is employed between the fluid pressurization output structure 600 and the centrifugal impeller 100.
Alternatively, the fluid pressurization output structure 600 and the centrifugal impeller 100 are respectively provided with a sub-driving shaft structure, and the sub-driving shafts of the two are structurally provided with a shaft structure connected to each other as a whole to transmit the power source of the total driving source.
In specific implementation, the fluid pressurization output structure 600 and the centrifugal impeller 100 may be driven by a driving source respectively.
It should be noted that, regardless of the common drive source structure or the sub-drive source structure adopted between the fluid pressurization output structure 600 and the centrifugal impeller 100, the drive source may be an internal drive source or an external drive source.
The fluid centrifugal through-flow action device with the fluid pressurization output structure can effectively increase the fluid output full pressure.
The structures shown in fig. 12-14 can be used in combination or individually as components in the corresponding positions of a fluid centrifugal flow activation device provided by the present invention, and can also be used individually or in combination in other fluid activation devices according to the effects that can be expected from the above structures.

The inlet flow amplification structure of the fluid action device provided by the invention can be applied to the embodiment of the fluid centrifugal cross-flow action device. It should be noted that the middle-section diversion strip enables the middle-section amplified fluid to generate a pre-rotation effect, and the pre-rotation orientation of the amplified fluid should be a mutual promotion mode matched with the rotation direction of the fluid in the diversion structure.
The term "middle stage" in the above-mentioned term "middle stage flow rate negative pressure amplification structure" refers to a stage after the driving means of the fluid action device and before the fluid outlet end of the fluid action device.
