Description

Technical Field

[0001] This invention belongs to the field of fluid power, and specifically relates to a novel fluid ejector. Background Technology

[0002] Existing fluid ejectors, such as compressors, turbojet engines, electronic fuel injection engines, chemical reaction jets, propellers, high-pressure water jets, and high-pressure water pumps, have fluid injection volumes limited by product power or fuel consumption. Ultimately, there is a bottleneck with a limit that cannot be increased further. Therefore, it is necessary to find ways to increase the fluid injection volume without increasing power or fuel consumption, while also making the injection flow rate adjustable. In addition, many existing fluid ejectors require both cooling of the ejector casing and cooling of the ejected fluid. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a novel fluid ejector. This invention is achieved through the following technical solution:

[0004] A novel fluid ejector includes a fluid ejection device and a fluid amplification device. The fluid amplification device consists of a multi-hole tail nozzle cover, a high-pressure fluid connecting pipe, and a fluid amplifier. The multi-hole tail nozzle cover is located at one end of the fluid ejection device and has several holes. One end of the high-pressure fluid connecting pipe is connected to the holes, and the other end is connected to the fluid amplifier.

[0005] The fluid jetting device is preferably a fluid jetting device 1. The high-pressure fluid ejected from the tail of the fluid jetting device 1 passes through the holes on the porous tail nozzle cover 2, which reduces the flow area and further increases the fluid pressure. The high-pressure fluid enters the fluid amplifier 4 through the high-pressure fluid connecting pipe 3. Due to the wall effect, the fluid amplifier 4 draws in multiple times the amount of fluid from the periphery and mixes with the high-pressure fluid from the fluid jetting device 1 before being ejected, forming a jet of fluid with a larger flow rate. At the same time, the outer shell of the fluid jetting device 1 and the jet fluid can be cooled.

[0006] The high-pressure fluid entering the fluid amplifier 4 via the high-pressure fluid connection pipe 3 can be gas or liquid. The fluid amplifier 4 can also draw in gas or liquid from the surrounding area. The high-pressure fluid and the fluid drawn in can be different. The mixed fluid ejected from the fluid amplifier 4 can be gas, liquid, or a gas-liquid mixture.

[0007] The high-pressure fluid connecting pipe is connected to the hole through a conical cavity. One end of the conical cavity is connected to the high-pressure fluid connecting pipe, and the other end is connected to the hole.

[0008] The number of holes is at least three, and the number of high-pressure fluid connecting pipes and fluid amplifiers corresponds to the number of holes; the fluid amplifier is an air amplifier or an optimized and improved structure of an air amplifier.

[0009] The fluid injection device is one of the following: compressor, chemical reaction explosion generator, engine, pulse ramjet, gas turbine, turbojet, turbo-ramjet, ramjet, pulsejet, propeller, high-pressure water injector, high-pressure water pump, and propeller. The engine is one of the following: electronic fuel injection engine, rocket engine, turbofan engine, turboprop engine, piston propeller engine, turboprop engine, turborocket engine, ducted fan engine, and propfan engine.

[0010] It also includes a guide tube, which is cylindrical and is mounted on the fluid jetting device via a connecting rod, enclosing both the fluid jetting device and the fluid amplification device. The opening at the end of the guide tube enclosing the fluid jetting device is a vacuum suction port, and the opening at the end enclosing the fluid amplification device is a main nozzle. The fluid ejected from the outer shell of the fluid jetting device 1, the guide tube 7, and the main nozzle 9 can all be cooled.

[0011] The vacuum suction port is not coaxially aligned with the fluid jetting device. By changing the structure, the fluid inlet of the guide tube 7, i.e., the vacuum suction port 10, can be in any position and any direction to achieve different needs and functions.

[0012] The multi-hole tail nozzle cover is also equipped with a fluid vent pipe, which has a flow control valve. By adjusting the flow control valve, the fluid pressure in the high-pressure fluid connection pipe 3 can be adjusted, thereby adjusting the fluid intake of the fluid amplifier 4 and controlling the flow rate of the total nozzle 9.

[0013] Both the vacuum inlet and the main nozzle are connected to movable steering pipes. These movable steering pipes are designed to be steerable, thereby controlling different air intake and jet directions to meet various needs.

[0014] Compared with existing technologies, this invention has the following beneficial effects: This invention provides a novel fluid ejector that, by improving the structure of existing fluid ejectors, achieves a multiple increase in the ejection flow rate, and both the entire casing surface of the fluid ejector and the ejected fluid can be cooled. This invention designs the tail nozzle seal of existing fluid ejectors as a multi-hole tail nozzle cover. Each small nozzle on the tail nozzle cover is connected to a fluid amplifier via a pipe. The high-pressure fluid ejected from the fluid ejector enters each fluid amplifier through these pipes, allowing for the absorption of more fluid from the periphery. This amplifies the fluid at the final ejection port of the device by multiple times, with the amplification reaching 3-25 times or even greater, achieving a significant increase in the ejection flow rate of a single fluid ejector without increasing energy consumption. This invention can be used as a vacuum generating device, a device for obtaining large-flow, high-pressure ejected fluid, or a high-energy power device. Attached Figure Description
