Detailed Description

In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

The most key concept of the invention is as follows: the windward side and the leeward side are communicated through a plurality of air vents, and the high-pressure fluid on the windward side is used for transferring pressure difference from the air vents to a low-pressure high-speed flow velocity layer to reduce the pressure of the fluid, so that pressure difference thrust in the front-to-back direction is generated, and the thrust of the power device is obviously improved.

The principle of the power device of the invention is specifically analyzed as follows:

the present invention therefore differs from the prior art power plant as follows:

1. the power device of the invention forms two high-speed flow velocity layers 303 with approximately same flow velocity and high flow velocity and low pressure on the lee side shell of the impeller and between the fluid channels.

2. The impeller is communicated between the windward side and the leeward side through a plurality of air vents, so that different fluid pressures respectively generated between the windward side and the leeward side are communicated with each other.

3. Therefore, under the action of the pressure difference, high pressure is generated from low flow velocity passing through the windward side of the impeller, and the low pressure generated by the high-speed flow velocity layer from the plurality of air vents to the leeward side is transferred to the pressure difference to generate the driving force, so that the fluid resistance of the impeller is remarkably reduced.

4. The power device of the invention forms a high-speed flow velocity layer 303 on the casing of the leeward side of the impeller and between the fluid channels, and the high-speed flow velocity layer 303 enables the fluid to pass through the length direction of the leeward side, therefore, the fluid passes through the width direction of the windward side of the impeller and the length direction of the leeward side, and pressure difference and driving force are generated due to different paths and different flow velocities.

5. The power device of the invention is driven by power or external force and is provided with various impellers with fan blades or without fan blades; the invention finds the pressure releasing port for the great fluid pressure borne by the windward side of the stressed surface, and the pressure difference driving force is generated by the communication of the plurality of air ports and the low pressure on the leeward side, in other words, the invention obtains the greater driving force from reducing the fluid resistance on the premise of not increasing the additional power.

Please refer to fig. 1-5: a power device comprises a rotating shaft and an impeller connected with the rotating shaft, wherein the impeller comprises a shell and is characterized in that the shell is provided with a plurality of blades; the impeller is characterized in that a fluid channel is arranged in the shell, at least two first air vents are formed in the leeward side of the shell and communicated with the fluid channel, the fluid channel is communicated with an exhaust port arranged at the farthest end of the shell, and the leeward side of the impeller is communicated with the windward side through an air pipe and/or a second air vent, so that the shell transfers pressure difference to the leeward side to generate driving force.

Please refer to fig. 1-6: a power plant comprises a multistage compressor and a multistage turbine, wherein at least one stage of impeller in the multistage compressor and the multistage turbine is the impeller in the power plant.

Please refer to fig. 3: a power device comprises a rotating shaft and an impeller connected with the rotating shaft, wherein the partial or whole part between the windward side and the leeward side of the impeller is communicated through a plurality of uniformly distributed air vents.

From the above description, the beneficial effects of the present invention are:

the high pressure on the windward side is utilized to generate the pushing force through the low pressure difference of the air vents to the leeward side.

Specifically, the power device generates high-pressure fluid at a low flow rate on the windward side of the impeller shell, and generates a high-flow-rate and low-pressure high-flow-rate layer at a high flow rate and a low pressure which are formed by the leeward side and the fluid channel together, and the high-pressure fluid on the windward side passes through the plurality of second air vents and/or the air ducts, and generates a driving force by a low pressure transfer pressure difference generated towards the leeward side high-flow-rate layer, so that the driving force can be obviously improved by reducing the fluid resistance on the premise of not increasing additional power.

Furthermore, at least two second air vents are arranged on the windward side of the shell and communicated with the fluid channel; the windward side of the shell is provided with at least two vent pipes communicated with the leeward side; the ventilation area of the first vent is larger than the ventilation areas of the second vent and the vent pipe.

Further, the device also comprises a flow disturbing device; and a turbulence device for prolonging a fluid passing path is arranged in the fluid channel, and the turbulence device is a concave-convex turbulence surface, a spiral turbulence surface or a spiral turbulence strip which is concave-convex on the surface.

Further, the exhaust port is arranged on the side opposite to the high rotation direction of the impeller.

Further, the device also comprises a high-speed fluid layer; the shell is partially or wholly provided with the high-speed fluid layer.

Further, the device also comprises an air suction motor and an air suction pipe connected with an air suction port of the air suction motor; the air suction pipe is communicated with the first air vent through a fluid channel.

Furthermore, the windward side and the leeward side of the shell are communicated and generate pressure difference due to different flow rates; the difference in flow velocity between the fluid passing across the windward side of the housing in the width direction and the fluid passing across the leeward side in the length direction creates a pressure differential.

Further, the device also comprises a hollow shell, a rotating shaft and a combustion chamber; the rotating shaft is coaxially and non-concentrically connected with a multistage compressor and a multistage turbine, and the multistage compressor, the combustion chamber and the multistage turbine are accommodated in a hollow shell.

Further, the fluid within the combustion chamber passes through fluid passages within each blade of at least one stage of the wheel of the turbine, allowing the fuel to take a long path for efficient combustion.

Furthermore, the power device comprises a rotating shaft and an impeller connected with the rotating shaft, wherein the partial or whole part between the windward side and the leeward side of the impeller is communicated through a plurality of uniformly distributed air vents.

The first embodiment of the invention is as follows:

referring to fig. 1-3, a power plant includes an impeller 1 connected to a shaft 2; a fluid channel 6 is arranged in the impeller shell, the fluid channel is communicated with a plurality of first air vents 4 uniformly distributed on the whole leeward surface 302 in the length direction, a turbulence device 7 which prolongs a fluid passing path and is concave-convex on the surface is arranged in the fluid channel 6, and the fluid channel is communicated with the end surface of the farthest end of the impeller shell in the length direction, namely an air outlet 8 at the tail part of the impeller shell at the blade tip position; a plurality of second air vents 5 which are communicated through a plurality of air pipes 9 and/or are uniformly distributed on the windward side are uniformly distributed between the whole windward side and the leeward side of the impeller and are communicated with the fluid channel.

Wherein the air intake area of the first air port 4 is larger than the air intake areas of the second air port 5 and the air pipe 9.

The flow disturbing device 7 includes: the turbulence surfaces, spiral turbulence strips and the like which are concave-convex on the surface can be used for prolonging the path of fluid passing through the fluid channel and accelerating the flow velocity of the fluid.

When the impeller 1 rotates at a high speed under the drive of power or external force, fluid which is equal to the movement speed of the impeller enters the fluid channel 6 from the plurality of large first air vents 4 on the leeward surface, and under the combined action of large suction force generated when the fluid flows through the fluid channel at a high speed and strong traction force generated by centrifugal force, the fluid near the first air vents 4 on the leeward surface 302 is sucked into the fluid channel at a high speed, and then the fluid near the plurality of first air vents 4 uniformly distributed on the whole leeward surface is sucked into the fluid channel at a high speed, so that the flow speed on the leeward surface 302 is accelerated, and then two high-speed fluid layers 303 which are mutually communicated and have approximately the same flow speed are formed on the leeward surface of the impeller and in the fluid channel communicated with the leeward surface.

Furthermore, the fluid passing through the windward side 301 of the impeller and having low flow velocity and generating high pressure and the fluid having low flow velocity and generating low pressure of the high-speed fluid layer 303 generate pressure difference due to different flow velocities, so that the great fluid pressure borne by the windward side of the stress surface finds the pressure leakage opening, and meanwhile, under the action of the pressure difference, the fluid passing through the high pressure from the windward side inevitably passes through the plurality of uniformly distributed vent pipes 9 to generate low pressure transfer pressure difference to the high-speed fluid layer 303 on the leeward side, so that the driving force in the front-to-back direction is generated.

Further, the windward side 301 of the impeller generates high-pressure fluid at a low flow rate, and pressure difference is transferred to the high-speed fluid layer 303 through a plurality of second air vents 5 uniformly distributed on the windward side to generate driving force.

Further, the windward side 301 of the impeller generates high-pressure fluid at low flow velocity, and a part of the high-pressure fluid transfers pressure difference to the high-speed fluid layer 303 on the leeward side through the air duct 9; and the other part of the impeller windward side 301 is low in flow speed and high in pressure, so that the pressure difference is transferred with the high-speed fluid layer 303 of the fluid channel through the plurality of second air vents 5.

The windward side of the impeller is communicated with the leeward side, and fluid passes through the low flow velocity of the windward side and generates high pressure, and is easy to pass through the high flow velocity of the leeward side and the generated low pressure transfer of a plurality of vent pipes 9 or/and second vent systems to generate pressure difference driving force from back to front under the direct action of pressure difference.

The fluid resistance generated by the movement of the impeller almost influences the maximum energy consumption of the power device; therefore, the communication relation between the plurality of ventilating pipes on the windward side and the second ventilating openings and the leeward side is reasonably designed, so that the large fluid pressure on the windward side of the stress surface transfers more fluid pressure outwards through the ventilating pipes and/or the second ventilating openings; further, the relationship between the first vent on the leeward side and the fluid channel and the exhaust port is reasonably designed; thereby fully utilizing the relation that the high pressure born on the windward side is inevitably transferred to the low pressure on the leeward side to generate the driving force \ and the pressure difference is generated; thereby significantly reducing the fluid resistance of the impeller.

The fluid resistance generated by the windward side and the leeward side of the traditional impeller influences the maximum energy consumption of the power device. Obviously, the high pressure generated on the windward side is bound to transfer the pressure difference to the low pressure of the leeward side to generate the driving force, and the same as the water flows to the low position is a natural law.

The only difference between the conventional impeller and the present invention is: the direction of the fluid pressure experienced by the impeller is different.

Further, in the conventional power device, fluid passes through the width direction of the windward side and the leeward side of the impeller; the fluid of the invention passes through the width direction of the windward side of the impeller and the length direction of the leeward side, so the path difference of the fluid between the length direction and the width direction of the leeward side and the windward side is larger, the generated pressure difference driving force is larger, and the energy-saving effect is larger.

Furthermore, a tail exhaust port is arranged at the position of the blade tip at the farthest end of the shell of the blade 3 of the impeller along the length direction and on the side opposite to the rotation direction of the impeller, so that high-speed fluid faster than the impeller is exhausted from the tail exhaust ports of the blades in the same direction at the same time, and the impeller rotates faster.

Furthermore, a fluid channel 6 is arranged on the leeward side of the casing of the impeller, which is far away from the front half part of the impeller along the length direction, namely, in the rear half part of the casing of the impeller, and is communicated with the tail exhaust port to form a high-speed fluid layer 303, so that the high pressure generated by the front half part of the impeller is transferred to the low pressure generated by the rear half part of the high-speed fluid layer 303, and the pressure is a driving force, thereby driving the impeller to rotate faster.

Furthermore, a plurality of first air vents are uniformly distributed on the same side surface position of the rotation direction of the impeller, namely the same side surface of the width direction of the leeward side in the rotation direction, along the length direction of the whole impeller, and are communicated with the tail air outlet through a fluid channel to form a high-speed fluid layer 303; therefore, the high pressure and low flow rate generated by the side opposite to the rotation of the impeller (without the high-speed fluid layer 303) must transfer the pressure difference to the high pressure and low flow rate generated by the high-speed fluid layer on the other side, thereby pushing the impeller to rotate faster.

Preferably, the impeller is provided with a high-speed fluid layer on the same side of the leeward side in the width direction of the blade surface, namely about 1/2 or 1/3 of the width of the blade surface, and particularly, the impeller with the wider blade surface can generate larger propelling force.

Further, a high-speed fluid layer 303 is provided on a part or the whole of the same side in the rotation direction of the impeller.

Further, a high-speed fluid layer 303 is arranged on the lee side of the rear half part in the shell of the impeller and/or a high-speed fluid layer 303 is arranged on the same side surface of the shell of the lee side of the impeller along the length direction of the whole impeller and the rotation direction of the impeller.

Fluid channels may also be provided in the impeller housing, partially or entirely, lengthwise, to form a high velocity fluid layer 303, partially or entirely, on the leeward side.

Furthermore, a flow disturbing device 7 is arranged in the fluid channel, preferably the flow disturbing device is a spiral flow disturbing strip, one or more spiral flow disturbing strips are uniformly arranged in the fluid channel, so that the fluid passes through the helical surface around the surface of the fluid in a circle and a circle, and the passing path of the fluid in the fluid channel is prolonged by multiple times.

Further, a spiral flow-disturbing surface is arranged on the whole or part of the periphery of the inner wall of the shell of the impeller; or the turbulent surface is concave-convex on the surface, so that the path of the fluid in the fluid channel is prolonged, and the flow speed of the fluid is remarkably accelerated.

Especially, the exhaust port 8 is arranged at the position of the blade tip of the impeller in the direction opposite to the rotation direction of the impeller, and the blades 3 simultaneously and in the same direction discharge high-speed fluid faster than the impeller from the exhaust port at the position of the blade tip in the direction opposite to the rotation direction of the blades, so as to jointly push the impeller to rotate faster.

Further, by removing the turbulence device 7, the fluid passing through the long and width directions of the windward side and the leeward side of the impeller can generate large pressure difference due to different paths and different flow rates.

Further, the power device of the invention is suitable for driving the impeller to move in water or air by power or external force; wherein the power drive is: the power device drives the impeller to move through various powers; the external force is as follows: the power generation device generates power by driving the impeller to move through external forces such as wind power, water power, firepower, nuclear power, solar energy and the like.

The power device of the invention comprises an impeller which is driven by power or external force to move in water or air.

The second embodiment of the invention is as follows:

referring to fig. 1-4, the power device is a wind driven generator driven by external force.

The length of the impeller of the wind power generation device is at least 20 times larger than the width of the impeller, meanwhile, a flow disturbing device is arranged in the fluid channel, and the path of the fluid passing through the fluid channel is prolonged by multiple times, so that a high-speed fluid layer 303 with higher flow speed is formed.

When wind power drives the impeller to rotate to generate a great centrifugal force, the fluid in the fluid channel 6 passes through the fluid channel in the length direction of the impeller instantly and is discharged from the exhaust port 8 at the blade tip under the action of the great power traction force of the centrifugal force, so that a high-speed fluid layer 303 is formed on the leeward side, and at least 20 times of high-speed fluid layer 303 is formed between the high-speed fluid layer and the slow flow velocity of the fluid passing through the width direction of the windward side, so that a larger pressure difference driving force is generated, the fluid resistance of the impeller is remarkably reduced, and the power generation efficiency of the generator is remarkably improved.

The invention is suitable for various external forces such as various waterpower, firepower, nuclear power, wind power, solar energy and the like to drive the impeller of the generator, so that the generating efficiency of the power device is obviously improved, and a brand new way is opened up for the development of the power device.

The third embodiment of the invention is as follows:

referring to fig. 1-5, unlike embodiment 2, the power plant is a water turbine power generation plant without blades driven by water flow. The water turbine comprises a stator and a rotor (common knowledge and not shown in the drawing) rotating in the stator, wherein the rotor is an impeller 1 connected with a rotating shaft 2 and is the water turbine.

A fluid channel 6 is arranged in the periphery of the water turbine shell, a flow disturbing device 7 is arranged in a half area in the fluid channel in the periphery of the water turbine shell and is a back water surface with high flow speed, a plurality of first water through openings are arranged on the back water surface and are communicated with the fluid channel, and therefore a high-speed fluid layer 303 is formed on the back water surface; the other half of the fluid channel is an upstream surface with slow flow rate because of no turbulent flow device, and a plurality of second water through holes 5 are arranged on the upstream surface and communicated with the fluid channel; the area between every two protruding parts around the shell of the water turbine is used as a blade 3, and at least one water outlet 8 is arranged at the rear part of each blade in the rotating direction on the back water surface and is communicated with the fluid channel; the water inlet area of the first water through opening is larger than that of the second water through opening, and the rest are the same as the above.

When the hydraulic driven water turbine rotates, the regions of the upstream surface and the downstream surface of the impeller rotate continuously, the high water pressure is generated at a low flow rate on the upstream surface in the rotation of the impeller under the impact of water flow, and a low water pressure transfer pressure difference is inevitably generated towards the high-speed fluid layer 303 of the downstream surface, so that the impeller is driven to rotate faster by the pressure difference driving force generated by different flow rates between the upstream surface and the downstream surface in the rotation of the water turbine, and the rest is the same as the above.

Further, at least one drain port 8 is eliminated, and only one larger drain port is provided in communication with the fluid passage at a position rearward of the high-speed fluid layer of the back surface, i.e., at a position farthest from the back surface in the rotational direction.

Further, for the screw blade wheel without the fan blades, the same as the above, the exhaust port 8 of the screw blade wheel is arranged at the rear part of the high-speed fluid layer on the leeward side and communicated with the fluid channel.

Further, the impeller is divided into an upper half and a lower half, the upper half of the impeller is regarded as a windward side with low flow rate, the lower half is regarded as a leeward side with high flow rate, for example, the upper half of the screw impeller is the windward side and the lower half is a high-speed fluid layer of the leeward side, and when the screw impeller rotates along with the spiral shape, due to the difference of flow rates between the upper and lower parts, a pressure difference from top to bottom is generated to drive the impeller to rotate faster.

Further, the impeller includes fan blades or no fan blades, the high-speed fluid layer is provided with fan blades or no fan blades, and the impeller is partially or integrally provided, wherein the impeller without fan blades can be in various geometric shapes, such as various impellers driven by power or external force, such as circular impellers, screw impellers, rolling simple impellers, eccentric impellers, and the like, and the description thereof is omitted.

Furthermore, one part around the impeller is set as the leeward side of the high-speed fluid layer, and pressure difference is generated between the leeward side of the high-speed fluid layer and the windward side of the low flow speed of the other part, and the pressure difference is driving force.

The power device of the invention comprises various impellers which are driven by power or external force and have different shapes and move with fan blades or without fan blades.

The fourth embodiment of the invention is as follows:

referring to fig. 1-6, the difference between the above is that the power device is a one-stage or multi-stage impeller 1 connected with a rotating shaft 2; first air vents 4 are uniformly distributed on the leeward surface 302 of at least one stage of impeller and are communicated with a tail air outlet 8 on the blade tip at the farthest end of the impeller shell in the length direction through a fluid channel 6; the windward side and the leeward side of the impeller are communicated through a plurality of uniformly distributed vent pipes 9 and/or a plurality of second vent holes 5 on the windward side are communicated with the first vent holes 4 on the windward side through fluid channels.

Furthermore, the first air vents uniformly distributed on the leeward side of the impeller can be communicated with the hollow rotating shaft 2 through the fluid channel 6, the hollow rotating shaft 2 is communicated with an air suction port of an air suction motor 305 arranged outside through an air suction pipe 306, an air exhaust port of the air suction motor is communicated with the outside, and the windward side and the leeward side of the impeller are communicated through a plurality of air vents 9 uniformly distributed.

When the impeller rotates at a high speed, the suction motor 305 generates strong suction force to suck fluid into the fluid channel 6 at a high speed from the first air vents 4 uniformly distributed on the leeward side of the impeller, so that a high-speed fluid layer 303 with a faster flow speed is generated on the leeward side, and a larger pressure difference driving force is generated between the low flow speed and the windward side.

Obviously, the suction motor 305 can easily accelerate the flow rate of the leeward side of the impeller and the flow channel with low energy consumption; for example, the suction motor can easily accelerate the flow velocity by multiple times, even ten times, so that a larger pressure difference is generated between the low flow velocity of the leeward side and the high flow velocity of the windward side.

Then, after the multi-stage impellers are accumulated step by step, a larger driving force is generated.

Furthermore, an air suction motor can be omitted, and because the flow speed of fluid passing through the length direction of the leeward side of the impeller and the width direction of the windward side of the impeller is different by multiple times, the impeller of each stage generates multiple pressure difference between the windward side and the leeward side due to different flow speeds, and generates larger driving force after the impellers are accumulated step by step.

The above structure can be used for various power devices such as various power-driven motors, fans, compressors, engines, or steam turbines.

Further, at least one stage of the impeller can be a household fan, and the pressure difference transfer layer 304 is formed between high pressure generated by a windward side and low pressure generated by a leeward side, so that the fan can rotate faster, and a remarkable energy-saving effect is achieved.

Furthermore, at least one stage of the impeller can be a propeller of an underwater power device, and a larger pressure difference driving force is generated between high pressure generated by the upstream surface of the propeller and low pressure generated by the downstream surface of the propeller, so that the driving force of the underwater movement device is improved, and the ship is driven to run faster to achieve a remarkable energy-saving effect.

Further, the at least one stage of impeller is various impellers driven by power or external force.

The fifth embodiment of the invention is as follows:

as shown in fig. 1 to 6, the power plant is a turbine engine including a multistage compressor 10, a combustion chamber 101, a multistage turbine 102, a rotating shaft 2, and a casing 103; wherein the multistage compressor and the multistage turbine are sequentially connected with the rotating shaft 2 coaxially and eccentrically and are accommodated in the hollow shell 103.

As described with reference to example four: in at least one stage of impellers of the multistage compressor and the multistage turbine, a plurality of first air vents 4 uniformly distributed on the leeward side are communicated with a tail air outlet 8 of the impeller shell at the farthest position in the length direction through a fluid channel 6 to form a high-speed fluid layer 303, so that the high pressure on the windward side is transferred to the low pressure on the leeward side to generate driving force.

The working process of the turbine engine of the embodiment is as follows: the rotating shaft 2 is driven by power to coaxially and eccentrically drive the multistage compressor 10 and the multistage turbine 102 to rapidly rotate, the fluid channel 6 in the impeller of at least one stage is communicated with the leeward side through the first air vent 4 to form a high-speed fluid layer 303, so that the high pressure on the windward side is transferred to the low pressure on the leeward side to generate driving force.

If the high pressure of the windward side of the impeller of each stage of the multistage compressor and the multistage turbine transfers the pressure difference to the low pressure of the leeward side to generate the driving force, the multistage impellers form the larger pressure difference driving force than the original driving force together after being accumulated step by step.

Furthermore, each stage of impeller generates multiple pressure difference between the windward side width and the leeward side length direction, and then the multi-stage impellers are gradually accumulated to obtain a larger driving force source.

When the engine works, fluid enters the engine from the air inlet 104, and the multistage compressors are gradually accumulated to generate large internal pressure and driving force; at this time, a plurality of nozzles in the combustion chamber 101 spray fuel to rapidly combust to generate high-temperature and high-pressure hot gas; at the moment, the combustion chamber is easier to fully combust fuel in a state that the multistage gas compressors jointly generate larger internal pressure; the burnt fluid is discharged from the gas outlet 8 through a long path of the fluid channel 6 in each blade 3 of the multistage turbine, because the continuity of the fluid enables the multistage turbine 4 to change the space under the state of no change of time in the high-speed motion state, the burnt fluid passes through a path which is increased by multiple times or even increased by dozens of times easily at a higher speed than the original path, and the fuel has the opportunity to be burnt more fully; it is equivalent to enlarging the internal space of the combustion chamber by several tens of times and then discharging a higher velocity fluid from the outlet 105 backward, so that the driving force of the engine is significantly increased.

For a power plant comprising multiple compressors and/or turbines: on the basis of the structure of the impeller, blades of each stage of the impeller of the multistage compressor and the multistage turbine form a high-speed fluid layer, so that the high pressure on the windward side transfers the pressure difference to the low pressure on the leeward side to generate driving force.

Furthermore, multiple pressure differences are generated by different paths and different flow rates of the fluid passing through the leeward side and the windward side of the impeller in the long and wide directions, and then the pressure differences are accumulated step by step to form a pressure difference driving force source larger than the original pressure difference driving force source.

Furthermore, the fluid channel in each stage of impeller of the multistage turbine is provided with a turbulent flow device which is concave-convex on the surface, thereby further prolonging the path of fluid passing through in the combustion chamber, increasing the path of fuel in the combustion chamber to be larger, and having the opportunity of being fully combusted, thereby generating larger driving force.

The fluid burned in the combustion chamber passes through the fluid channel in each blade in each stage of impeller of the turbine, is discharged, passes through and is discharged again, and then fully burns through a long path.

Referring to fig. 3, a sixth embodiment of the present invention:

different from the embodiments 1-5, the impeller is not provided with the fluid channel 6, and the leeward side and the windward side of the impeller are communicated through a plurality of uniformly distributed air vents 9; because the windward side is a stress surface and bears most of fluid pressure, and the leeward side is a suction surface and bears less fluid pressure; therefore, the leeward side and the windward side are communicated through the uniformly distributed plurality of air vents 9, so that the large fluid pressure borne by the windward side of the stress surface finds the pressure release port, and is discharged from the uniformly distributed plurality of air vents 9 to the leeward side, and the fluid resistance is reduced by the discharged fluid pressure, thereby reducing the fluid resistance of the impeller.

Further, between the leeward side and the windward side of the impeller, the front, middle, rear, or required part or whole is communicated through a plurality of air ports 9.

In summary, the power device of the present invention is various impellers driven by power or external force and having different shapes and having fan blades or no fan blades, and since the windward side and the leeward side of the impeller are communicated with each other, the high pressure on the windward side is fully utilized to inevitably transfer the pressure difference to the low pressure on the leeward side to generate the driving force, so that the driving force of the power device is significantly improved on the premise of not increasing additional power.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
