Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cylinder covers, in particular to a sealed cylinder cover. Background Art
[0002] The refrigeration compressor drives the crankshaft to rotate through the motor, and the crankshaft drives the connecting rod to make the piston reciprocate, thereby realizing the circulation of low-temperature and low-pressure refrigerant vapor into high-temperature and high-pressure gas. This repetitive pushing of the working fluid forms a refrigeration cycle.
[0003] The cylinder head used in traditional piston compressors is made of metal materials such as aluminum or aluminum alloy. When the compressor is discharged, the heat generated by the high-temperature and high-pressure refrigerant will be transferred to the cylinder head through the cylinder head, causing the cylinder head temperature to be too high and causing harmful heating of the refrigerant sucked into the cylinder, reducing the thermal efficiency of the compressor and thus reducing the performance of the compressor.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0023] The following describes an embodiment of the present invention based on its overall structure.
[0024] A sealed cylinder head, such as Figures 1 to 5As shown, it includes a cover body 100, a ladder plate 110 is fixed on the top of the cover body 100, two sets of air inlet channels 111 are reserved laterally in the ladder plate 110, and a buffer assembly is assembled inside the bottom end of the cover body 100;
[0025] The buffer assembly includes a buffer plate 120 slidably disposed within the cover body 100. The top inner wall of the cover body 100 defines a plurality of piston cavities 160. A piston 140 is movably sleeved within each piston cavity 160. The bottom end of the piston 140 is provided with a piston rod 130 fixed to the top of the buffer plate 120. The top edge of the buffer plate 120 is provided with a plurality of springs 150 fixed to the top of the cover body 100. The interior of the cover body 100 is provided with a plurality of return tubes 190 connected to the piston cavity 160 on both sides thereof.
[0026] A channel 180 is defined at the top of the cover body 100 and is connected to the top of the piston chamber 160 . The other end of the channel 180 is connected to the air inlet channel 111 .
[0027] When the compressed air in the cylinder generates pressure on the bottom end of the cover body 100, the buffer plate 120 can be moved upward, compressing the spring 150 while also pushing the piston rod 130 into the piston chamber 160, causing the piston 140 to push upward in the piston chamber 160 and compressing the air inside the piston chamber 160 to enter the return tube 190. The air is then forced to flow in the return tube 190, absorbing the heat inside the cover body 100 and eventually discharging it to the outside.
[0028] On the contrary, when there is no upward pressure on the buffer plate 120, the spring 150 will release the pressure to lower the buffer plate 120, and the piston 140 will move downward in the piston chamber 160, and the outside air will enter the piston chamber 160 through the air inlet channel 111 and the channel 180. When the piston 140 rises next time, the air can be transported to the return tube 190 again, so that the outside air can be continuously drawn into the cover body 100, thereby achieving an air-cooling effect on the cover body 100.
[0029] Please refer to Figure 3 、 Figure 4 and Figure 5 A matching frame groove 170 is formed at the contact position between the inner wall of the cover body 100 and the buffer plate 120 .
[0030] The frame groove 170 is used to fix the stroke of raising and lowering the buffer plate 120, ensuring that the compressed air in the cylinder is not affected.
[0031] Please refer to Figure 1 and Figure 2 Threaded holes 101 are provided at the top of the cover body 100 near the four corners.
[0032] The bolts can be connected to the cylinder body through the threaded holes 101 to achieve a sealing effect.
[0033] Please refer to Figure 1 and Figure 2 The two ends of the return tube 190 extend from the front and rear surfaces of the cover body 100 respectively.
[0034] The air flowing through the return pipe 190 is discharged and can be continuously circulated to take away the heat inside the cover body 100 .
[0035] Please refer to Figure 3 , multiple groups of springs 150 are distributed on the top of the buffer plate 120 and near the corners.
[0036] The buffer plate 120 can be lifted and lowered linearly according to a preset trajectory, thereby achieving the purpose of buffering and protecting the cover body 100 .
[0037] Please refer to Figure 4 A one-way valve is assembled in the return tube 190 and the end of the channel 180 close to the piston chamber 160.
[0038] When the piston 140 rises in the piston chamber 160, the one-way valve in the channel 180 is in a closed state, and the one-way valve in the return tube 190 is in an open state. At this time, the gas inside the piston chamber 160 can enter the return tube 190 and eventually be discharged to the outside. On the contrary, the outside air enters the piston chamber 160 through the channel 180, so that the outside air can be continuously transported to the return tube 190 for the purpose of air cooling and heat dissipation.
[0039] During use, when the compressed air in the cylinder generates pressure on the bottom end of the cover body 100, the buffer plate 120 can be moved upward, and while compressing the spring 150, the piston rod 130 can also be pushed into the piston cavity 160, so that the piston 140 is pushed upward in the piston cavity 160, and the air inside the piston cavity 160 is compressed to enter the return tube 190, so that the air flows in the return tube 190, which can absorb the heat inside the cover body 100 and finally discharge it to the outside;
[0040] On the contrary, when there is no upward pressure on the buffer plate 120, the spring 150 will release the pressure to lower the buffer plate 120, and the piston 140 will move downward in the piston chamber 160, and the outside air will enter the piston chamber 160 through the air inlet channel 111 and the channel 180. When the piston 140 rises next time, the air can be transported to the return tube 190 again, so that the outside air can be continuously drawn into the cover body 100, thereby achieving an air-cooling effect on the cover body 100.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
