According to the invention, fuel is input into the combustion chamber 40, the spark plug 41 is ignited to generate high-pressure fuel gas, and then the high-pressure fuel gas is sprayed into the main cylinder 20 which is compressed by bouncing through the gas outlet pipe 50 to raise the gas pressure, so that the piston 23 of the cylinder obtains stronger power, the bouncing force and height are increased, and the advantages of low noise, strong and continuous power, cleanness and sanitation are achieved.
In an embodiment of the present invention, the magnetic switch 24 is disposed at the lower side of the cylinder 21, the piston 23 is magnetized, and when the piston 23 and the magnetic switch 24 trigger the magnetization, the solenoid valve 63 opens the fuel pipe 60, so that the operation is smoother.
In a preferred embodiment, a safety valve 81 and a manual valve 82 are installed on the upper side of the cylinder 21, wherein the safety valve 81 plays a safety protection role. When the pressure in the cylinder 21 exceeds a predetermined value, the safety valve 81 is opened to discharge a part of the gas so that the pressure in the cylinder 21 does not exceed an allowable value, thereby ensuring that the master cylinder 20 does not have an accident due to an excessive pressure. The manual valve 82 is adjusted manually, and the use function is enhanced. Further, the air outlet 83 is provided below the cylinder 21 to achieve an exhaust effect, and the muffler 120 may be additionally provided to perform silencing.
The combustion chamber 40 is connected to the cylinder 21 through an intake pipe 51, and a one-way fuel valve 61 is provided between the fuel pipe 60 and the combustion chamber 40 in such a manner that the intake of fuel is completed and high-pressure gas is finally generated by combustion in the combustion chamber 40, the fuel pipe being connected to the intake pipe 51.

With continued reference to FIG. 1, at the beginning of the bounce, the piston rod 22 presses against the bottom of the master cylinder 20, firstly the movement of the piston 23 completes the suction action in the cylinder 21, and secondly the piston 23 continues to move and the air in the master cylinder 20 starts to compress and accumulate energy. At the same time, the gas in the outlet pipe 50 at the upper end of the combustion chamber 40 is also compressed into the combustion chamber 40, which provides for the ignition of the following combustion chamber 40. When the bouncing action reaches the lowest point and begins to bounce, the air pressure in the cylinder 21 reaches the highest point, the piston rod 22 begins to move in the reverse direction, the linkage rod 71 connected with the piston rod starts to act together, the detection switch 70 in contact with the linkage rod 71 is triggered and sends out a signal, the signal triggers the spark plug 41 to ignite in the combustion chamber 40, the highly-compressed combustible mixed gas in the combustion chamber 40 forms deflagration, the high-pressure gas rushes into the main cylinder 10 from the bottom of the main cylinder 10 to pressurize the compressed air, a larger driving force is generated for the piston 23, the impact force of the gas can enable the piston 23 to obtain another power, and the two powers complete boosting in the bouncing process. When the piston 23 moves to the air outlet 83, the air in the cylinder 21 is communicated with the atmosphere, and the air pressure returns to the initial state, and the rebound operation is also ended. The piston 23 continues to move due to inertia into the lower cylinder 21 to complete the pumping operation. The action of removing the waste gas in the combustion chamber 40 and the gas outlet pipe 50 thereof is also completed in the process, and the mixing of the fuel and the air is completed and the mixture is injected into the combustion chamber 40. Thus, the next bounce compression action is prepared. Therefore, the device can be used for the next cycle and then run all the time in a cycle to generate strong and continuous bounce assisting work.
With continued reference to fig. 2 and 3, fig. 2 is a schematic view of a bouncer power assisting device according to another embodiment of the present application; fig. 3 is a schematic compression diagram of fig. 2. The air inlet pipe 51 is communicated with the air outlet pipe 50, and the power assisting mechanism 90 is arranged between the combustion chamber 40 and the air outlet pipe 50, so that a further power assisting pushing effect is realized.
Specifically, assist mechanism 90 includes helping hand cylinder 91, and helping hand cylinder 91 has helping hand cylinder piston 92, helping hand cylinder piston rod 93, and combustion chamber piston 94, and wherein helping hand cylinder piston rod 93 is connected helping hand cylinder piston 92 and combustion chamber piston 94, and helping hand cylinder 91 upper end intercommunication outlet duct 80, helping hand cylinder piston 92 to helping hand cylinder 94 bottom are equipped with cylinder spring 94. In the present embodiment, the boost cylinder piston rod 93 is connected to the boost cylinder piston 92 and the combustion chamber piston 94 at the upper and lower ends thereof, respectively, to complete the boost butt joint between the boost cylinder 91 and the combustion chamber 40, thereby generating linkage.
Further, an exhaust pipe 100 is provided at the bottom of the combustion chamber 40, a shutter mechanism 110 is attached to the exhaust pipe 100, and when the piston rod 22 of the master cylinder 20 is lowered to the lowest position, the shutter mechanism 110 opens the exhaust pipe 100 to complete the exhaust operation in the combustion chamber 40. Preferably, the exhaust pipe 100 is provided with a silencer 120 to reduce noise generated.
In an embodiment of the present invention, the shutter mechanism 110 includes a shutter 111 that opens and closes the exhaust pipe 100; the lower end of the valve 111 is provided with a spring; a lever 112 pressing against the lower end of the valve 111, wherein the lever 112 is connected with the lower mounting seat 30 through a pull rope 113; when the lower mounting seat 30 descends to the lowest position, the pull rope is tightened, the lever 112 is pulled, the valve 111 is lifted, the pressure of the combustion chamber 40 is relieved, and meanwhile, the cylinder spring 94 in the power-assisted cylinder 91 contracts to drive the combustion chamber piston 94 to descend and reset.
As shown in fig. 2 to 3, the main cylinder 20 is first pulled away, the gas in the main cylinder 20 starts to be compressed when the bounce compression is performed, air and fuel are simultaneously injected into the combustion chamber 40, and the combustion chamber 40 finishes filling gas when the main cylinder 20 is pressed to the lowest point. When the bouncing motion starts bouncing at the same time, the detection switch 70 detects the motion to trigger the ignition of the ignition plug 41. The combustible mixed gas in the combustion chamber 40 is ignited to generate deflagration to form high-pressure gas, the high-pressure gas pushes the piston 23 and drives the boosting cylinder piston 92 to move together, the boosting cylinder piston 92 presses air into the main cylinder 20 to increase the air pressure, and the piston 23 in the main cylinder 20 obtains stronger power. When the piston 23 of the main cylinder 20 reaches the farthest position, the pull rope 113 on the lower mounting seat 30 will pull the air outlet valve 111 of the combustion chamber 40 to release the pressure, and the cylinder spring 95 in the boost cylinder 91 will contract to pull the boost cylinder piston 92 back, and the combustion chamber piston 94 in the combustion chamber 40 will return to the original position. Since the piston 23 in the main cylinder 20 also passes through the air outlet 83, the air pressure in the cylinder 21 is equal to the atmospheric pressure. The device returns to the original loading state, and then the next cycle action can be carried out, so that strong and continuous bounce assisting work is generated.
In summary, the present invention inputs fuel into the combustion chamber 40, the ignition plug 41 ignites to generate high pressure fuel gas, and then the outlet pipe 50 injects the high pressure gas into the main cylinder 20 which is compressed by bouncing to raise the air pressure, so that the piston 23 obtains stronger power, thereby increasing the strength and height of bouncing, and having the advantages of low noise, strong and continuous power, cleanness and sanitation.
