In order to avoid damage to the compressor caused by the high internal temperature when the piston moves repeatedly, it is necessary to discharge the high-temperature gas in time. In addition, the piston may be damaged when it moves repeatedly, resulting in greater wear and tear during the compression and exhaust exchange process of the compressor.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] See also Figure 1-Figure 8As shown, a cylinder split multi-row closed labyrinth compressor comprises a labyrinth compressor body 1, wherein the labyrinth compressor body 1 is provided with a multi-row compression chamber 2, wherein the compression chamber 2 is provided with a first piston 3, a second piston 4 and a connecting rod 8, wherein the two ends of the connecting rod 8 are respectively connected to the first piston 3 and the second piston 4, and the first piston 3 and the connecting rod 8 are both slidably connected to the interior of the compression chamber 2, and the crankshaft inside the labyrinth compressor body 1 can be rotated by a motor, and the crankshaft can drive the rocker to push the first piston 3, the second piston 4 and the connecting rod 8 to rise and fall, so that the first piston 3 and the second piston 4 are lifted and lowered inside the compression chamber 2, and when the second piston 4 moves upward, the air inside the compression chamber 2 is compressed, and at the same time, the temperature of the compressed air becomes high, which easily causes the temperature inside the compression chamber 2 to become high, and a cooling structure 5 is provided inside the labyrinth compressor body 1 and at the upper end of the compression chamber 2, and the cooling structure 5 comprises a plurality of reserved grooves 51, wherein the reserved grooves 51 are provided between two adjacent compression chambers 2, and the first connecting holes 52 and the second connecting holes 53 are provided on both sides inside the reserved grooves 51, and the first connecting holes 53 are provided on both sides inside the reserved grooves 51. The hole 52 is located above the second connecting hole 53. The first connecting hole 52 and the second connecting hole 53 are both connected to the compression chamber 2 on both sides of the reserved groove 51, so that the air flow inside the compression chamber 2 flows when the second piston 4 rises and falls in the compression chamber 2. A second floating cover 56 is installed inside the first connecting hole 52, and the second floating cover 56 is rotatably connected to the inner wall of the first connecting hole 52. A first floating cover 54 is installed inside the second connecting hole 53, and the first floating cover 54 is rotatably connected to the inner wall of the second connecting hole 53. The second floating cover 56 and the first floating cover 54 on the same side rotate in opposite directions. The second floating cover 56 can be opened to the inside of the compression chamber 2, and the first floating cover 54 can be opened to the inside of the reserved groove 51. A heat dissipation aluminum plate 55 is installed inside the reserved groove 51, and the heat dissipation aluminum plate 55 is used to dissipate the heat inside the compression chamber 2. The heat generated when the second piston 4 compresses the air inside the compression chamber 2 can be conducted through the heat dissipation aluminum plate 55, so that the hot air in the compression chamber 2 can be quickly discharged as much as possible, and the temperature will not be too high when the air is compressed for a long time.

[0039] See also Figure 3-Figure 5 As shown, the top ends of the first floating cover 54 and the second floating cover 56 are integrally provided with connecting pins, and the top inner walls of the first connecting hole 52 and the second connecting hole 53 are provided with pin holes, and the connecting pins of the first floating cover 54 and the pin holes of the second connecting hole 53 are detachably installed, and the connecting pins of the second floating cover 56 and the pin holes of the first connecting hole 52 are detachably installed, and the first floating cover 54 and the second floating cover 56 are detachably installed, and the first floating cover 54 and the second floating cover 56 are inserted into the first connecting hole 52 and the second connecting hole 53, and it is ensured that the second floating cover 56 can rotate freely inside the first connecting hole 52, and the first floating cover 54 can rotate freely inside the second connecting hole 53, thereby realizing the opening and closing of the first floating cover 54 and the second floating cover 56.

[0040] See also Figure 6 As shown, when the top end of the second piston 4 moves upward along the inside of the compression chamber 2 to the position of the first floating cover 54, the first floating cover 54 and the second floating cover 56 are both in an open state. When the second piston 4 moves upward, the airflow is compressed so that the first floating cover 54 and the second floating cover 56 are opened, so that the reserved groove 51 and the internal air pressure of the compression chamber 2 are at the same pressure.

[0041] See also Figure 7 As shown, when the top end of the second piston 4 moves upward from the position of the first floating cover 54 along the inside of the compression chamber 2, the first floating cover 54 and the second floating cover 56 are both in a closed state; when the second piston 4 moves upward between the first floating cover 54 and the second floating cover 56, the second floating cover 56 is blocked by the second piston 4 and thus closed, and similarly the first floating cover 54 is also closed; when the top end of the second piston 4 moves downward along the inside of the compression chamber 2 to the position of the first floating cover 54, the second floating cover 56 is in a closed state, and the first floating cover 54 is in an open state; when the second piston 4 moves downward, the airflow below the compression chamber 2 flows out from the first floating cover 54.

[0042] See also Figure 8 As shown, when the top end of the second piston 4 moves downward from the position of the second floating cover 56 along the inside of the compression chamber 2, the second floating cover 56 is in an open state, and when the second piston 4 moves downward between the second floating cover 56 and the first floating cover 54, the top end of the compression chamber 2 is in a negative pressure state, so that the second floating cover 56 is opened.

[0043] The crankshaft inside the labyrinth compressor body 1 can be rotated by a motor, and the crankshaft can drive the rocker to push and thereby push the first piston 3, the second piston 4 and the connecting rod 8 to rise and fall, so that the first piston 3 and the second piston 4 rise and fall inside the compression chamber 2. When the second piston 4 moves upward, the air inside the compression chamber 2 is compressed, and at the same time, the temperature of the compressed air increases, which easily causes the temperature inside the compression chamber 2 to increase. When the second piston 4 moves upward, it compresses the airflow so that the first floating cover 54 and the second floating cover 56 are opened, so that the reserved groove 51 and the air pressure inside the compression chamber 2 are at the same pressure. When the second piston 4 moves upward between the first floating cover 54 and the second floating cover 56, the second floating cover 56 is blocked by the second piston 4 Thus, it is closed, and the first floating cover 54 will also be closed. The first floating cover 54 is in an open state. When the second piston 4 moves downward, the air flow under the compression chamber 2 flows out from the first floating cover 54. When the second piston 4 moves downward between the second floating cover 56 and the first floating cover 54, the top of the compression chamber 2 is in a negative pressure state, so that the second floating cover 56 is opened. By opening or closing the first floating cover 54 and the second floating cover 56, the second piston 4 moves upward to discharge the hot air of the previous stroke after compression inside the compression chamber 2 in time, thereby avoiding damage to the compressor caused by the high temperature inside the compression chamber 2; when the second piston 4 moves downward, the compression chamber 2 in a negative pressure state is filled with air, thereby reducing the power loss of the first piston 3 during the return stroke.

[0044] See also Figure 2 , Fig. 9 and Fig.10 As shown, a buffer structure 6 is provided inside the labyrinth compressor body 1 and between the first piston 3 and the second piston 4. The buffer structure 6 includes a fixed sleeve 61, which is embedded in the labyrinth compressor body 1. The buffer structure 6 can be installed inside the labyrinth compressor body 1. A placement groove 62 is provided inside the fixed sleeve 61. A telescopic spring 63 is placed inside the placement groove 62 and at each first piston 3. The telescopic spring 63 is placed inside the placement groove 62, so that the telescopic spring 63 is compressed and extended inside the placement groove 62. A floating plate 64 is provided at the bottom end of the placement groove 62. Both ends of the telescopic spring 63 are respectively connected to the fixed sleeve 61 and the floating plate 64. A contact block 65 is integrally provided on the inner wall of the floating plate 64. The contact block 65 corresponds to the top surface of the first piston 3. After the first piston 3 moves upward, the first piston 3 contacts the contact block 65 of the floating plate 64, so that the contact block 65 and the floating plate 64 can be moved upward, and the telescopic spring 63 is used to reduce the impact of the first piston 3.

[0045] See also Fig.10As shown, the floating plate 64 is slidably connected to the inside of the placement groove 62, and a connecting ring 66 is connected between the contact blocks 65, and the connecting ring 66 corresponds to the top of the first piston 3, and a sealing ring 67 is pasted on the lower surface of the connecting ring 66, and the outer diameter of the sealing ring 67 is adapted to the inner diameter of the compression chamber 2.

[0046] After the first piston 3 moves upward, the first piston 3 contacts the contact block 65 of the floating plate 64, so that the contact block 65 and the floating plate 64 can be moved upward, and the telescopic spring 63 is used to reduce the impact of the first piston 3. When the first piston 3 moves the floating plate 64 to the extreme position, the floating plate 64 fits with the inside of the placement groove 62, and the first piston 3 is in close contact with the sealing ring 67, so that the deformed sealing ring 67 can block the gap, thereby reducing the leakage of the air flow inside the compression chamber 2. When the first piston 3 moves upward to the extreme position, the first piston 3 is limited by the contact block 65, and the telescopic spring 63 can reduce the impact of the contact block 65, prevent the first piston 3 from moving beyond the stroke, and also reduce the damage of the piston parts; through the connecting ring 66 and the sealing ring 67 of the buffer structure 6, the top of the first piston 3 contacts the sealing ring 67, thereby preventing dust in the compression chamber 2 from entering the bottom of the first piston 3.

[0047] See also Figure 2 , Fig.11 and Fig.12 As shown, a dust removal structure 7 is provided between the placement groove 62 and the reserved groove 51, and the dust removal structure 7 includes a threaded hole 71, the threaded hole 71 is opened at the bottom end of the reserved groove 51, and the internal thread of the threaded hole 71 is connected with a threaded sleeve 72, the threaded hole 71 is screwed into the inside of the threaded sleeve 72, and a fixing block 73 is welded at the bottom end of the threaded sleeve 72. A plurality of exhaust holes 74 are opened inside the fixing block 73. Under normal circumstances, airflow can flow inside the threaded sleeve 72 and the fixing block 73. The reserved groove 51 and the placement groove 62 are connected through the threaded sleeve 72 and the exhaust holes 74. A partition plate 75 is installed inside the grooved sleeve 72, and filter holes are opened on the surface of the partition plate 75, and a collecting hole 76 is integrally provided on the lower surface of the partition plate 75 and located at the filter hole. The collecting hole 76 is used for one-way passage of dust in the compression chamber 2. When the air pressure at the top end of the compression chamber 2 is greater than the air pressure at the bottom end of the compression chamber 2, the dust at the top end of the compression chamber 2 will flow from the bottom end of the compression chamber 2. At this time, the dust flows from the collecting hole 76 of the partition plate 75. The inverted eight-shaped collecting hole 76 can prevent the dust from flowing back to the top end of the compression chamber 2, and it can fall from the bottom end of the exhaust hole 74.

[0048] See also Fig.11As shown, the shape of the collecting hole 76 is an inverted eight-shaped shape, and the top diameter of the collecting hole 76 is larger than the bottom diameter of the collecting hole 76. The top diameter of the collecting hole 76 is compatible with the filter hole diameter of the partition plate 75. The collecting hole 76 can prevent dust from flowing back to the top of the threaded sleeve 72 or the inside of the reserved groove 51.

[0049] See also Fig.12 As shown, an intermediate ball 77 is placed between the threaded hole 71 and the threaded sleeve 72, and a limiting ring 78 is provided on the inner wall of the upper end of the fixed block 73. The intermediate ball 77 is located between the spacer plate 75 and the limiting ring 78, and the diameter of the intermediate ball 77 is between the inner diameter of the threaded sleeve 72 and the inner diameter of the limiting ring 78. The air pressure at the top of the compression chamber 2 is greater than the air pressure at the bottom of the compression chamber 2. After the intermediate ball 77 descends, the limiting ring 78 and the intermediate ball 77 are in contact to prevent the air flow from flowing. The air pressure at the top of the compression chamber 2 is much smaller than the air pressure at the bottom of the compression chamber 2, so that the intermediate ball 77 is separated from the limiting ring 78, so that the dust accumulated last time can fall into the exhaust hole 74, and the dust falls from the inside of the fixed block 73 to the lower end of the labyrinth compressor body 1, so that the dust can enter the exhaust hole 74 from the collecting hole 76, and the dust can also be prevented from accumulating in the dust removal structure 7.

[0050] When the air pressure at the top of the compression chamber 2 is greater than the air pressure at the bottom of the compression chamber 2, the dust at the top of the compression chamber 2 will flow from the bottom of the compression chamber 2. At this time, the dust will flow from the collecting hole 76 of the partition plate 75. The collecting hole 76 in the shape of an inverted figure eight can prevent the dust from flowing back to the top of the compression chamber 2, and can fall from the bottom of the exhaust hole 74. The partition plate 75 can make the dust flow downward in one direction, and not too much dust will accumulate inside the compression chamber 2. The shape of the collecting hole 76 can also prevent the dust from flowing back to the top of the compression chamber 2. The placement groove 62 and the floating plate 64 are close and far away so that the dust inside the fixed block 73 is discharged; the cooling structure 5 and the dust removal structure 7 cooperate with each other, and the middle ball 77 and the limiting ring 78 are in contact when the second piston 4 moves upward, which can prevent the airflow from leaking when the second piston 4 compresses the air. When the second piston 4 moves downward, the middle ball 77 is separated from the limiting ring 78, which can allow the dust to enter the exhaust hole 74 from the collecting hole 76, and can also prevent the dust from accumulating in the dust removal structure 7.
