[0025] An arch-shaped limiting block 23 is fixed to the outer wall of the annular inner combination part 2 in a corresponding manner through welding, an arch-shaped clamping block 44 is fixed to the inner wall of the piston friction part 4 in a corresponding manner through welding, and the arch-shaped limiting block 23 and the arch-shaped clamping block 44 are movably clamped to each other; when the arch-shaped limiting block 23 and the arch-shaped clamping block 44 are centered, the position of the annular inner combination part 2 is fixed, so that the piston is prevented from being loosened due to general accidental rotation, only when the piston friction part 4 is rotated by using a larger force, the arch-shaped clamping block 44 is deformed, and finally the arch-shaped clamping block 44 and the arch-shaped limiting block 23 are separated from each other, so that the connection firmness is improved;

[0026] The arch-shaped clamping block 44 is made of elastic material, an elastic element 45 is connected between one side of the arch-shaped clamping block 44 and the inner wall of the piston friction part 4, an anti-skid pattern 41 is fixed to the outer wall of the piston friction part 4 through welding, and the piston smooth part 11 is fixed to the outer wall of the generator shell 1 through welding; the arch-shaped clamping block 44 can be kept in the original position through the elastic element 45, the arch-shaped clamping block 44 is bent due to stress when the piston friction part 4 is rotated, the elastic element 45 is deformed, at this time, the piston friction part 4 is conveniently rotated, the elastic element 45 stores energy, the elastic potential energy of the elastic element 45 is released after alignment, the arch-shaped clamping block 44 is abutted on the arch-shaped limiting block 23 through elastic force at this time, and the two are conveniently centered;

[0027] The outer wall of the annular inner combination part 2 is correspondingly provided with a small air hole 22, the small air hole 22 and the gap between the two arched limiting blocks 23 are mutually penetrated, the outer wall of the piston friction part 4 is correspondingly provided with a large air hole 43, the large air hole 43 and the space between the two arched clamping blocks 44 are mutually penetrated; when the two arched clamping blocks 44 are aligned with the arched limiting blocks 23, that is, when the installation clamping position is reached, the small air hole 22 and the large air hole 43 are mutually penetrated, at this time, the exchange of air inside and outside the annular inner combination part 2 can be realized, because the current passes through the pin contact 3 when in use, heat is generated to cause the temperature rise inside the annular inner combination part 2, and heat exchange facilitates heat dissipation;

[0028] The inner wall of the internal combustion chamber 12 is correspondingly connected with a tree-shaped embedded pipe 72 through welding penetration, one end of the tree-shaped embedded pipe 72 is flush with the inner wall of the internal combustion chamber 12, and the tree-shaped embedded pipe 72 is in penetration cooperation with the large air hole 43, the two tree-shaped embedded pipes 72 are commonly connected with a gas exchange hose 7 at one end, the gas exchange hose 7 is provided with a pump air device 71, and the pump air device 71 is in penetration connection with an external cold air source;

[0029] The inner wall of the annular inner combination part 2 is uniformly provided with a plurality of lubricating oil inner holes 92, the top outer wall of the piston friction part 4 is correspondingly provided with a lubricating oil outer hole 91, the inner wall of the anti-skid pattern 41 is uniformly provided with a lubricating oil seepage groove 93, and the annular inner combination part 2 is provided with a lubricating oil pump 99; the external cold air pump air device is pumped into the tree-shaped embedded pipe 72 through the start of the pump air device 71, and then pumped into the inside of the shell of the piston friction part 4, and the cold air finally reaches the inside of the annular inner combination part 2, so that the supply of cold air is realized, and the heat generated by the friction of the piston is prevented from deforming;

[0030] The width of the arc-shaped inner plate 42 is less than the width of the notch, and the width of the arc-shaped outer plate 21 is greater than the width of the arc-shaped inner plate 42; because the arc-shaped inner plate 42 is less than the width of the notch, it can be completely staggered during rotation, so that the generator shell 1 can completely extend into the piston friction part 4, and after clamping, because the width of the arc-shaped outer plate 21 is greater than the arc-shaped inner plate 42, the arc-shaped outer plate 21 is uniformly stressed, and is not disconnected due to pulling;

[0031] The inside of the lubricating oil outer hole 91 and the lubricating oil inner hole 92 is provided with a check valve 100; the cold air reaching the inner wall of the annular inner combination part 2 is discharged from the lubricating oil inner hole 92 and the lubricating oil outer hole 91 through heat exchange, and finally discharged to the outside through the lubricating oil seepage groove 93, forming a circulating loop of heat exchange air, and preventing gas backflow through the check valve 100, preventing external air or liquid from entering the inside of the annular inner combination part 2, and improving the sealing performance of the piston.

[0032] Embodiment: The working of the present application is divided into heat exchange state and dust removal state. When the large air hole 43 is aligned with the small air hole 22, it is the heat exchange state, at this time the piston is also in the working state, the flow direction of the gas will pass through the annular inner joint 2. When the large air hole 43 is misaligned with the small air hole 22, it is the dust removal state. Most of the gas in the large air hole 43 cannot enter the inside of the annular inner joint 2, but directly enters the gap between the annular inner joint 2 and the piston friction part 4, blows the dust at the connecting part from inside to outside, compared with the conventional state of blowing gas from the outside to remove dust, this kind of way will not blow the dust further into the device, and when disassembling, it will not cause disassembling difficulty due to dust accumulation.
