Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical engineering, and specifically discloses a gas power generating device. Background Art

[0002] In structural engineering design, linear motion actuators are often required. Generally, motors, compression springs, high-pressure gases, gunpowder, fuel engines, etc. are used as power sources. However, in actual use scenarios, these traditional mechanisms have limitations. For example, the torque of motors is limited and a speed reducer is needed to amplify the torque. Spring energy storage often requires other power sources for energy storage. High-pressure gases require a gas source for supply. Gunpowder is restricted in transportation, storage, and daily use. Engines need to be pre-ignited and operate stably before they can be used. In some environments that require quick response, large stroke, and large load, they are often not suitable. Against this technical background, the present invention proposes a power generating device that utilizes the combustion of combustible gas to do work. Summary of the Invention

[0003] To solve the above technical problems, the present invention proposes a gas power generating device. By utilizing the combustion of combustible gas to do work, the power is directly output without passing through conversion devices such as speed reducers and levers, and can output power with quick response, large stroke, and large impact, and can be used as the power source for machinery such as impact drills, automatic rock drilling bits, cutters, and simulation launchers.

[0004] To achieve the above object, the technical solution adopted by the present invention is: A gas-powered generating device, characterized in that: it includes a cylinder block assembly and a piston assembly. The cylinder block assembly includes a cylinder block, a one-way valve, and an ignition electrode. The bottom of the cylinder block is provided with an oxidant gas inlet hole and a fuel gas inlet hole, and the side wall is provided with an exhaust hole. The piston assembly includes a piston, an exhaust rod plug, an exhaust rod, a piston return spring, an exhaust rod return spring, and an exhaust rod pressing cap. The piston is movably installed in the cylinder block and forms a combustion chamber between the piston and the bottom of the cylinder block, and an exhaust chamber is formed between the piston and the side wall of the cylinder block. The oxidant gas inlet hole and the fuel gas inlet hole are respectively communicated with the combustion chamber, and the exhaust hole is communicated with the exhaust chamber. The one-way valve is installed in the oxidant gas inlet hole. An igniter installation hole communicated with the combustion chamber is also provided on the bottom of the cylinder block, and the ignition electrode is installed in the igniter installation hole. A first exhaust passage and an installation passage that communicate with each other are provided inside the piston. The exhaust rod plug is movably arranged in the first exhaust passage, and the exhaust rod is movably installed in the installation passage. The exhaust rod plug is connected to one end of the exhaust rod. A second exhaust passage, an exhaust gas inlet hole, and an exhaust gas outlet hole are provided inside the exhaust rod. The second exhaust passage communicates with the first exhaust passage through the exhaust gas inlet hole and communicates with the exhaust chamber through the exhaust gas exhaust hole. The piston return spring is sleeved on the piston, and the exhaust rod return spring is sleeved on the exhaust rod. It also includes a piston limit cap, an air extraction spring limit seat, an air extraction spring, and a push head. The piston limit cap is fixedly installed at the opening of the cylinder block and presses the piston return spring. The air extraction spring limit seat is installed on the piston limit cap and sleeved on the exhaust rod pressing cap. The air extraction spring is installed on the air extraction spring limit seat and is located between the air extraction spring limit seat and the exhaust rod pressing cap. The push head is fixed to the other end of the exhaust rod opposite to the exhaust rod plug.

[0005] In the above structure: A gas-powered generating device proposed by the present invention includes a cylinder block assembly, a piston assembly, a piston limit cap, an air extraction spring limit seat, an air extraction spring, and a push head. Among them, the cylinder block assembly includes a cylinder block, a one-way valve, and an ignition electrode, and the piston assembly includes a piston, an exhaust rod plug, an exhaust rod, a piston return spring, an exhaust rod return spring, and an exhaust rod pressing cap. This application does not need to rely on a flywheel for energy storage. By compressing combustible gas, it directly uses the gas to push the piston to do work, and completes actions such as resetting, exhausting, and inhaling through springs.

[0006] The cylinder block assembly can use the one-way valve to automatically inhale air inside the combustion chamber through the movement of the piston assembly, provide an oxidant for the next combustion, and seal the gas during combustion. The cylinder block can be used as the negative electrode for ignition, and the ignition electrode as the positive electrode. When the combustion chamber is filled with combustible gas, the negative ignition voltage is applied to the cylinder block, and the positive voltage is applied to the ignition electrode, and an arc can be generated through tip discharge to ignite the combustible gas. An exhaust hole is provided on the side wall of the cylinder block. When the piston assembly moves backward to the end position, the exhaust hole opens, and the high-pressure gas can be discharged from the exhaust hole.

[0007] A first exhaust passage is provided inside the piston, and a second exhaust passage is provided inside the exhaust rod. The second exhaust passage is communicated with the first exhaust passage through the exhaust gas inlet, and is communicated with the exhaust chamber through the exhaust gas outlet. When the piston moves, the first exhaust passage and the second exhaust passage inside the piston and the exhaust rod are closed to ensure the sealing of the fuel gas. When the piston moves forward under the action of the piston return spring, the first exhaust passage and the second exhaust passage inside the piston and the exhaust rod are opened, and the exhausted gas after combustion can be completely discharged.

[0008] The piston assembly, the air extraction spring positioning seat, and the air extraction spring can restrict the initial position of the piston assembly, ensuring that there is an initial volume inside the power generating device to accommodate a certain amount of combustible gas. When the piston assembly recoils under the fuel gas pressure, since there is a load behind the push head, at this time, the push head will press the exhaust rod, causing the exhaust rod plug to closely adhere to the inner wall of the first exhaust passage inside the piston, thereby closing the first exhaust passage. When the piston assembly recoils in place, the push head continues to recoil a small distance under the action of inertia, driving the exhaust rod to move. The exhaust rod drives the exhaust rod plug to move together, and the exhaust rod plug disengages from the inner wall of the first exhaust passage inside the piston, and the first exhaust passage is opened. At this time, the second exhaust passage inside the exhaust rod is also in an open state. The piston assembly moves forward under the action of the piston return spring, and the air extraction spring limit seat impacts the piston limit cap. The piston continues to move forward under the action of inertia, squeezing the exhausted gas in the chamber through the piston, and exhausting all the exhausted gas through the first exhaust passage inside the piston and the second exhaust passage inside the exhaust rod, and starts to compress the air extraction spring. The air extraction spring rebounds to drive the piston to reset, causing a certain initial volume to be generated inside the combustion chamber. At this time, the inside of the combustion chamber is in a negative pressure state, and air is drawn into the combustion chamber through the one-way valve in the cylinder block assembly. After reaching air pressure balance, the one-way valve is closed, and the exhaust rod spring squeezes the exhaust rod forward and drives the exhaust rod plug to move so that it closely adheres to the inner wall of the first exhaust passage, thereby closing the first exhaust passage inside the piston and the second exhaust passage inside the exhaust rod to complete the sealing.

[0009] The working principle of this application is as follows: 1. Initial stage: Through the action between the air extraction spring and the piston assembly via the air extraction spring seat, the piston assembly is restricted to the initial position, creating a certain space between the piston assembly and the front end of the cylinder block, which is the combustion chamber. In the initial state, the combustion chamber is filled with air. When the exhaust rod return spring pushes the exhaust rod forward, the exhaust rod drives the exhaust rod plug to move together, blocking the first exhaust passage with the exhaust rod plug. At this time, the first exhaust passage inside the piston is closed, and the second exhaust passage inside the exhaust rod is also in a closed state, and the inside of the fuel gas power generating device is sealed.

[0010] 2. Combustion and work stage: When the combustible gas is sprayed into the combustion chamber from the conveying channel, it is fully mixed with the air in the combustion chamber. The negative electrode of the high-voltage ignition voltage is applied to the cylinder block, and the positive electrode is applied to the ignition electrode. The high voltage breaks down the mixed gas in the combustion chamber to generate an arc, which ignites the mixed gas in the combustion chamber. The combustion of the combustible gas releases a large amount of heat, causing the gas to expand and push the piston to move backward. At this time, since there is a load behind the push head, the push head squeezes the exhaust rod towards the piston direction, driving the exhaust rod plug to move together, and blocking the first exhaust channel through the exhaust rod plug, ensuring that both the first exhaust channel inside the piston and the second exhaust channel inside the exhaust rod are in a closed state. The piston does work while moving backward and compresses the piston return spring at the same time. When the rear end of the piston hits the piston limit cap, it stops, completing the working stage.

[0011] 3. Reset stage After the piston completes its work, the piston will open the exhaust hole on the cylinder block, and most of the combustion exhaust gas will be discharged therefrom. The piston makes a reset movement forward under the action of the piston return spring. At this time, the piston is the driving part, and the exhaust rod and the push head are the driven parts. Due to the action of inertia force, the exhaust rod and the push head will move backward a small distance relative to the piston. At this time, the first exhaust channel inside the piston is opened. During the forward movement of the piston, all the exhaust gas in the combustion chamber will pass through the first exhaust channel, the exhaust gas inlet, the second exhaust channel, and the exhaust gas outlet in sequence, and be squeezed into the exhaust chamber, and then through the exhaust chamber and the exhaust hole, all of it is squeezed out of the power generating device. When the air extraction spring limit seat moves forward with the piston and hits the piston fixing cap, the piston assembly continues to move forward due to inertia and begins to squeeze the air extraction spring until the piston assembly hits the bottom of the cylinder block. At this time, the exhaust rod and the push head continue to move forward and under the action of the exhaust rod return spring, the exhaust rod drives the exhaust rod plug to move, and blocks the first exhaust channel through the exhaust rod plug, closing the first exhaust channel inside the piston, and the second exhaust channel inside the exhaust rod is also in a closed state. The piston moves backward under the action of the air extraction spring, leaving the initial volume of the combustion chamber. At this time, the inside of the combustion chamber is in a negative pressure state, and the atmospheric pressure outside the gas power generating device acts on the one-way valve, causing the one-way valve to open backward, and air enters the combustion chamber. After the pressure inside and outside the combustion chamber is balanced, the valve is closed, and the gas power generating device completes the reset. At this time, as long as combustible gas is sprayed in again and ignited, it can enter the combustion working stage again to complete the cycle.

[0012] Furthermore, it also includes a fixing pin, and the push head is fixedly installed behind the exhaust rod through the fixing pin.

[0013] In the above structure: In this application, the connection and fixation between the push head and the exhaust rod are realized by setting the fixing pin.

[0014] Further: The cylinder block assembly further includes a check valve retaining ring and a check valve spring. The check valve retaining ring is fixed on the check valve, and the check valve spring is sleeved on the check valve and located between the check valve retaining ring and the cylinder block.

[0015] In the above structure: The cylinder block assembly in this application further includes a check valve retaining ring and a check valve spring. When the inside of the combustion chamber is in a negative pressure state, air is drawn into the combustion chamber through the check valve in the cylinder block assembly. After the pressure inside and outside the combustion chamber reaches equilibrium, the check valve moves forward under the action of the check valve spring to close the valve of the check valve.

[0016] Further: The cylinder block assembly further includes an insulating ceramic insulating sleeve, and the ceramic insulating sleeve is installed in the igniter installation hole and sleeved on the ignition electrode.

[0017] In the above structure: The cylinder block assembly of this application further includes an insulating ceramic insulating sleeve, and the ceramic insulating sleeve is installed in the igniter installation hole for protecting the ignition electrode and insulating it.

[0018] Further: The fuel gas inlet hole communicates with a delivery channel for delivering combustible gas.

[0019] In the above structure: The delivery channel is used to deliver combustible gas, and the combustible gas enters the combustion chamber through the fuel gas inlet hole.

[0020] Further: The first exhaust channel is arranged in a funnel shape with a large bottom and a small mouth, and the exhaust rod plug is located inside the funnel mouth.

[0021] In the above structure: The first exhaust channel is arranged in a funnel shape with a large bottom and a small mouth, so that when the exhaust plug blocks the first exhaust channel, the sealing effect is better.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention does not require flywheel energy storage. The exhaust and intake structures enable the motion generator to output power without waiting for the engine to reach a stable working state through a heat engine, so it can respond faster and can perform one or more actions independently. Since there is no need for a crankshaft to compress fuel, a longer stroke can be achieved. Each action is performed independently, enabling it to be applicable to harsh working conditions without worrying about flameout problems. Compared with an electric motor, it does not require a speed reduction mechanism to increase torque and can output linear motion without a conversion mechanism. Compared with a compressed gas actuator, it does not require a compressor and has a longer endurance than compressed gas. Compared with a gunpowder power source, it can perform actions multiple times and is more flexible and safe in storage, transportation, and use. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the cylinder block 1-1 is further provided with an igniter installation hole communicated with the combustion chamber 8, and the ignition electrode 1-6 is installed in the igniter installation hole. The piston 2-1 is internally provided with a first exhaust passage 2-7 and an installation passage that are communicated with each other. The exhaust rod plug 2-2 is movably arranged in the first exhaust passage 2-7. The exhaust rod 2-3 is movably installed in the installation passage. The exhaust rod plug 2-2 is connected to one end of the exhaust rod 2-3. The exhaust rod 2-3 is internally provided with a second exhaust passage 2-8, an exhaust gas inlet hole, and an exhaust gas outlet hole. The second exhaust passage 2-8 is communicated with the first exhaust passage 2-7 through the exhaust gas inlet hole and is communicated with the exhaust chamber 10 through the exhaust gas exhaust hole 9. The piston return spring 2-4 is sleeved on the piston 2-1, and the exhaust rod return spring 2-5 is sleeved on the exhaust rod 2-3. It further includes a piston limit cap 3, an air extraction spring limit seat 4, an air extraction spring 5, and a push head 7. The piston limit cap 3 is fixedly installed at the opening of the cylinder block 1-1 and presses the piston return spring 2-4. The air extraction spring limit seat 4 is installed on the piston limit cap 3 and sleeved on the exhaust rod compression cap 2-6. The air extraction spring 5 is installed on the air extraction spring limit seat 4 and is located between the air extraction spring limit seat 4 and the exhaust rod compression cap 2-6. The push head 7 is fixed to the other end of the exhaust rod 2-3 opposite to the exhaust rod plug 2-2. It further includes a fixing pin 6, and the push head 7 is fixedly installed behind the exhaust rod 2-3 through the fixing pin 6. The cylinder block assembly 1 further includes a check valve retaining ring 1-3 and a check valve spring 1-4. The check valve retaining ring 1-3 is fixed on the check valve 1-2, and the check valve spring 1-4 is sleeved on the check valve 1-2 and is located between the check valve retaining ring 1-3 and the cylinder block 1-1. The cylinder block assembly 1 further includes an insulating ceramic insulating sleeve 1-5. The ceramic insulating sleeve 1-5 is installed in the igniter installation hole and sleeved on the ignition electrode 1-6. The fuel gas inlet hole is communicated with a conveying channel 12 for conveying combustible gas. The first exhaust passage 2-7 is arranged in a funnel shape with a large bottom and a small mouth, and the exhaust rod plug 2-2 is located inside the funnel mouth.

[0028] A gas-powered generating device proposed by the present invention includes a cylinder block assembly 1, a piston assembly 2, a piston limit cap 3, an air extraction spring limit seat 4, an air extraction spring 5, and a push head 7. Among them, the cylinder block assembly 1 includes a cylinder block 1-1, a one-way valve 1-2, and an ignition electrode 1-6. The piston assembly 2 includes a piston 2-1, an exhaust rod plug 2-2, an exhaust rod 2-3, a piston return spring 2-4, an exhaust rod return spring 2-5, and an exhaust rod compression cap 2-6. This application does not rely on a flywheel for energy storage. By compressing combustible gas, it directly uses the gas to push the piston 2-1 to do work, and completes actions such as resetting, exhausting, and inhaling through springs.

[0029] The cylinder block assembly 1 can utilize the one-way valve 1-2 to automatically inhale air inside the combustion chamber 8 through the movement of the piston assembly 2, provide an oxidant for the next combustion, and seal the gas during combustion. The cylinder block 1-1 can serve as the negative electrode for ignition, and the ignition electrode 1-6 as the positive electrode. When the combustion chamber 8 is filled with combustible gas, the negative ignition voltage is applied to the cylinder block 1-1, and the positive voltage is applied to the ignition electrode 1-6. An arc can be generated through tip discharge to ignite the combustible gas. An exhaust hole 9 is provided on the side wall of the cylinder block 1-1. When the piston assembly 2 moves backward to the end position, the exhaust hole 9 opens, and the high-pressure gas can be discharged from the exhaust hole 9.

[0030] A first exhaust passage 2-7 is provided inside the piston 2-1, and a second exhaust passage 2-8 is provided inside the exhaust rod 2-3. The first exhaust passage 2-7 is connected to the second exhaust passage 2-8 through an exhaust gas inlet and is connected to an exhaust chamber 10 through an exhaust gas outlet. When the piston 2-1 moves, the first exhaust passage 2-7 and the second exhaust passage 2-8 inside the piston 2-1 and the exhaust rod 2-3 are closed to ensure the sealing of the gas. When the piston 2-1 moves forward under the action of the piston return spring 2-4, the first exhaust passage 2-7 and the second exhaust passage 2-8 inside the piston 2-1 and the exhaust rod 2-3 open, and the exhaust gas after combustion can be completely discharged.

[0031] The piston assembly 2, the positioning seat of the air extraction spring 5, and the air extraction spring 5 can constrain the initial position of the piston assembly 2, ensuring that there is an initial volume inside the power generating device to accommodate a certain amount of combustible gas. When the piston assembly 2 recoils under the gas pressure, since there is a load behind the push head 7, at this time, the push head 7 will press the exhaust rod 2-3, causing the exhaust rod plug 2-2 to be in close contact with the inner wall of the first exhaust passage 2-7 in the piston 2-1, thus closing the first exhaust passage 2-7. When the piston assembly 2 recoils to the end position, the push head 7 continues to recoil a small distance under the action of inertia, driving the exhaust rod 2-3 to move. The exhaust rod 2-3 drives the exhaust rod plug 2-2 to move together. The exhaust rod plug 2-2 disengages from the inner wall of the first exhaust passage 2-7 in the piston 2-1, and the first exhaust passage 2-7 is opened. At this time, the second exhaust passage 2-8 in the exhaust rod 2-3 is also in an open state. The piston assembly 2 recoils forward under the action of the piston return spring 2-4. The air extraction spring limit seat 4 impacts the piston limit cap 3. The piston 2-1 continues to move forward under the action of inertia, squeezing the exhaust gas in the chamber through the piston 2-1, and exhausting all the exhaust gas through the first exhaust passage 2-7 inside the piston 2-1 and the second exhaust passage 2-8 in the exhaust rod 2-3, and starts to compress the air extraction spring 5. The rebound of the air extraction spring 5 drives the piston 2-1 to reset, making a certain initial volume generated inside the combustion chamber 8. At this time, the inside of the combustion chamber 8 is in a negative pressure state, and air is drawn into the combustion chamber 8 through the one-way valve 1-2 in the cylinder block assembly 1. After reaching air pressure balance, the one-way valve 1-2 is closed. The exhaust rod spring 2-5 squeezes the exhaust rod 2-3 forward and drives the exhaust rod plug 2-2 to move so that it closely adheres to the inner wall of the first exhaust passage 2-7, thus closing the first exhaust passage 2-7 in the piston 2-1 and the second exhaust passage 2-8 in the exhaust rod 2-3 to complete the sealing.

[0032] The working principle of this application is specifically as follows: 1. Initial stage: Through the interaction between the air extraction spring 5 and the piston assembly 2 via the air extraction spring 5 seat, the piston assembly 2 is restricted to the initial position, creating a certain space between the piston assembly 2 and the front end of the cylinder block 1-1, which is the combustion chamber 8. In the initial state, the combustion chamber 8 contains air. When the exhaust rod return spring 2-5 pushes the exhaust rod 2-3 forward, the exhaust rod 2-3 drives the exhaust rod plug 2-2 to move together, blocking the first exhaust passage 2-7 through the exhaust rod plug 2-2. At this time, the first exhaust passage 2-7 inside the piston 2-1 is closed, and the second exhaust passage 2-8 in the exhaust rod 2-3 is also in a closed state, and the inside of the gas power generating device is sealed.

[0033] 2. Combustion and work stage: When the combustible gas is injected into the combustion chamber 8 through the delivery channel 12, it mixes fully with the air in the combustion chamber 8. The negative pole of the high-voltage ignition voltage is applied to the cylinder block 1-1, and the positive pole is applied to the ignition electrode 1-6. The high voltage breaks down the mixed gas in the combustion chamber 8 to generate an electric arc, which ignites the mixed gas in the combustion chamber 8. The combustion of the combustible gas releases a large amount of heat, causing the gas to expand and push the piston 2-1 to move backward. At this time, since there is a load behind the push head 7, the push head 7 squeezes the exhaust rod 2-3 towards the piston 2-1, driving the exhaust rod plug 2-2 to move together. The first exhaust channel 2-7 is blocked by the exhaust rod plug 2-2, ensuring that both the first exhaust channel 2-7 inside the piston 2-1 and the second exhaust channel 2-8 inside the exhaust rod 2-3 are in a closed state. While moving backward to do work, the piston 2-1 compresses the piston return spring 2-4. When the rear end of the piston 2-1 hits the piston limit cap 3, it stops, completing the working stage.

[0034] 3. Reset stage After the piston 2-1 finishes working, the piston 2-1 will open the exhaust hole 9 on the cylinder block 1-1, and most of the combustion exhaust gas will be discharged therefrom. The piston 2-1 makes a reset movement forward under the action of the piston return spring 2-4. At this time, the piston 2-1 is the driving part, and the exhaust rod 2-3 and the push head 7 are the driven parts. Due to the action of inertia, the exhaust rod 2-3 and the push head 7 will move backward a small distance relative to the piston 2-1. At this time, the first exhaust channel 2-7 inside the piston 2-1 is opened. During the forward movement of the piston 2-1, all the exhaust gas in the combustion chamber 8 is successively discharged into the exhaust chamber 10 through the first exhaust channel 2-7, the exhaust gas inlet, the second exhaust channel 2-8, and the exhaust gas outlet. Through the exhaust chamber 10, it is all discharged outside the power generating device through the exhaust hole 9. When the air extraction spring limit seat 4 moves forward with the piston 2-1 and hits the piston 2-1 fixing cap, the piston assembly 2 continues to move forward due to inertia and starts to squeeze the air extraction spring 5 until the piston assembly 2 hits the bottom of the cylinder block 1-1. At this time, the exhaust rod 2-3 and the push head 7 continue to move forward and, under the action of the exhaust rod return spring 2-5, the exhaust rod 2-3 drives the exhaust rod plug 2-2 to move, and the first exhaust channel 2-7 is blocked by the exhaust rod plug 2-2, closing the first exhaust channel 2-7 inside the piston 2-1, and the second exhaust channel 2-8 inside the exhaust rod 2-3 is also in a closed state. The piston 2-1 moves backward under the action of the air extraction spring 5, leaving the initial volume of the combustion chamber 8. At this time, the inside of the combustion chamber 8 is in a negative pressure state, and the atmospheric pressure outside the gas power generating device acts on the one-way valve 1-2, causing the one-way valve 1-2 to open backward, and air enters the combustion chamber 8. After the internal and external pressures of the combustion chamber 8 are balanced, the valve is closed, and the gas power generating device completes the reset. At this time, as long as combustible gas is injected again and ignited, it can enter the combustion working stage again to complete the cycle.

[0035] In this embodiment: In the present application, the connection and fixation between the push head 7 and the exhaust rod 2-3 are achieved by setting the fixing pin 6.

[0036] In this embodiment: The cylinder block assembly 1 in the present application further includes a check valve retaining ring 1-3 and a check valve spring 1-4. When the inside of the combustion chamber 8 is in a negative pressure state, air is drawn into the combustion chamber 8 through the check valve 1-2 in the cylinder block assembly 1. After the internal and external pressures of the combustion chamber 8 reach equilibrium, the check valve 1-2 moves forward under the action of the check valve spring 1-4 to close the valve of the check valve 1-2.

[0037] In this embodiment: The cylinder block assembly 1 of the present application further includes an insulating ceramic insulating sleeve 1-5. The ceramic insulating sleeve 1-5 is installed in the igniter installation hole to protect the ignition electrode 1-6 and insulate it.

[0038] In this embodiment: The delivery channel 12 is used to deliver combustible gas, and the combustible gas enters the combustion chamber 8 through the fuel gas inlet hole.

[0039] In this embodiment: The first exhaust channel 2-7 is set in a funnel shape with a large bottom and a small opening, so that when the exhaust plug blocks the first exhaust channel 2-7, the sealing effect is better.

[0040] The present invention does not require flywheel energy storage. The exhaust and intake structures enable the action generator to output power without waiting for the engine to reach a stable working state after warm-up, thus enabling faster response and allowing it to perform one or more actions individually. Since there is no need for a crankshaft to compress fuel, a longer stroke can be achieved. Each action is performed individually, enabling it to be applicable to harsh working conditions without worrying about flameout. Compared with an electric motor, it does not require a speed reduction mechanism to increase torque and can output linear motion without a conversion mechanism. Compared with a compressed gas actuator, it does not require a compressor and has a longer endurance than compressed gas. Compared with a gunpowder power source, it can perform actions multiple times and is more flexible and safe in storage, transportation, and use.

[0041] The above is only a preferred embodiment of the present invention and does not impose any other form of limitation on the present invention. Any modification or equivalent change made based on the technical essence of the present invention still falls within the scope of protection required by the present invention.
