When the invention is used, it is connected to the air inlet of the combustion device, for example, the air inlet of the engine. As shown in FIG. 4 and FIG. 5, the use mode of the present invention is used alone, and the engine 30 is provided with an air inlet 301. The end of the intake hose 301 is connected to one end of the intake hose 31, and the other end of the intake hose 31 is fitted to the output pipe 162 of the casing 10 of the present invention, so that the installation is completed, and the installation process is very easy. Further, as shown in FIG. 6, a plurality of uses of the present invention are used. When the present invention is applied to an engine 30 having a plurality of intake ports 301, such as the engine 30 of a ship, the plurality of intake ports 301 can pass through multiple The intake hoses 31 connect a plurality of outlet tubes 162 of the present invention such that each of the inlets 301 of the engine 30 can benefit from the increased pressure of the input air by the present invention.

Referring to the first preferred embodiment of the present invention shown in FIG. 5, the air in the environment will be from the rear end of the first flow path A and the second flow path D. The rear ends are respectively attracted into the inside of the casing 10.

The air that is drawn into the first flow path A that is repeatedly bent and extended by the environment is attracted by the plurality of guide pieces 13 because the flow path is longer than the second flow path D, and the flow rate is slowed down, plus the flow The time travels along the curved first flow path A, so that the air flow of the final slowing speed will flow into the air chamber B from the side of the air chamber B, and gradually accelerates along the inner circumferential surface of the tapered portion 1611, and then The moving manner of the spiral flows out to the output flow path c of the output pipe 162; in contrast, the air flowing into the second flow path D of the air intake member 20 from the environment is the fastest because the flow path is the shortest and there is no obstruction in the middle. The speed flows forward to the front end of the second flow path D, and is ejected toward the middle of the output flow path c inside the output pipe 162.

Since the velocity of the air ejected from the front end of the second flow path D is faster than the air velocity gradually starting to accelerate forward around the air chamber B, the central output tube is made by the difference in speed between the two and the difference in flow direction. The direct injection airflow in 162 can be mutually drawn with the surrounding spiral moving airflow, and a vortex is formed between the airflow directly flowing in the center and the surrounding airflow, so that the air flowing forward in the air chamber B is not only the width of the air. The gradually decreasing tapered section 1611 can achieve the effect of forward acceleration by means of a nozzle, and can further utilize the eddy current between the airflows to enhance the pressure and speed of the air outputted from the output flow passage c of the output pipe 162, so that the connection is The fuel in the engine 30 of the invention can increase the intake efficiency of the intake port 301 due to the formation of a low pressure region inside the intake port 301, so that the fuel in the engine 30 can be completely burned, the fuel consumption is reduced, the horsepower of the engine 30 is enhanced, and the engine 30 is reduced.

Within port 301. Referring to FIG. 7, the engine 30 is provided with an air inlet 301. An air inlet hose 31 is connected to the output pipe 162 of the casing 10 of the present invention. The air inlet hose 31 is inserted into one end of the air inlet 301. There is a gap between the intake hose 31 and the intake port 301 in the port 301.

Thus, when the airflow accelerated by the present invention flows out of the intake port 301 from the output flow path c, the negative pressure formed inside the intake port 301 will be the air around the outer side of the intake port 301 from the intake hose 31 and the output. The gap between the tubes 162 is drawn into the air inlet 301, further increasing the amount of air input into the air inlet 301, further improving the efficiency of fuel combustion in the combustion device such as the engine 30, enhancing the horsepower of the engine 30 and reducing the carbon deposit of the ignition device.
