[0038] It should be noted that the one-way valve in the air inlet pipe 32 can only allow external gas to enter the compression pipe 31 ; the one-way valve in the air outlet pipe 33 can only allow the gas in the compression pipe 31 to enter the gas storage tank 2 .

[0039] Reference Figure 3 , Figure 5 and Figure 8 , wherein the compression assembly includes a piston plate 4, which is slidably connected in the piston tube 3, a compression chamber 41 is opened in the mobile frame 1, a seesaw shaft 42 is fixedly connected in the compression chamber 41, a linkage plate 43 is rotatably connected on the seesaw shaft 42, a first hinge seat 431 is fixedly connected to the top of the linkage plate 43 and the bottom of the piston plate 4, a push-pull rod 44 is rotatably connected between the two groups of first hinge seats 431, a reciprocating screw rod 45 is rotatably connected in the compression chamber 41, a sliding block 46 is threadedly sleeved on the outer wall of the reciprocating screw rod 45, a side wall of the sliding block 46 is fixedly connected to a second hinge seat 461, a linkage rod 462 is fixedly connected in the second hinge seat 461, the other end of the linkage rod 462 is fixedly connected to the side wall of the linkage plate 43, a driving motor 47 is fixedly connected to the top of the mobile frame 1, and the output shaft of the driving motor 47 is fixedly connected to the top of the reciprocating screw rod 45.

[0040] By setting the above structure, the driving motor 47 is turned on to drive the reciprocating screw 45 to rotate, so that the sliding block 46 moves back and forth up and down along the reciprocating screw 45. When the sliding block 46 moves downward, it will pull the side of the linkage plate 43 close to the sliding block 46 to rotate downward, so that the side of the linkage plate 43 away from the sliding block 46 is lifted upward, thereby pushing the push-pull rod 44 to push the piston plate 4 to move upward, thereby compressing the gas in the piston tube 3 and opening the one-way valve in the outlet pipe 33, so that the gas is compressed along the outlet pipe 33. When the sliding block 46 moves upward, the linkage plate 43 will rotate in the opposite direction, thereby pulling the piston plate 4 downward through the push-pull rod 44, thereby generating suction in the piston tube 3, thereby opening the one-way valve in the air inlet pipe 32, so that the external gas is sucked into the piston tube 3, and so on and so forth, and gas will be continuously filled into the air tank 2, thereby increasing the air pressure in the air tank 2, thereby completing the air compression, and in conjunction with the arrangement of the four groups of piston tubes 3 and the air outlet pipe 33, the gas compression efficiency is effectively improved.

[0041] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 The cooling assembly includes a cooling groove 5, which is provided in the side wall of the piston tube 3. The plurality of cooling grooves 5 are connected to each other through a circulation pipe 51. A pneumatic disc 52 is fixed and connected to the air outlet pipe 33. A pneumatic impeller 521 is rotatably connected to the air outlet pipe 33. A hydraulic disc 53 is fixed and connected to the circulation pipe 51. The rotating shaft of the pneumatic impeller 521 passes downward into the hydraulic disc 53 and is fixedly connected to the hydraulic impeller 531. A lubricating ring 6 is fixedly connected to the piston tube 3. A liquid storage pipe 61 is fixedly connected to the bottom of the air outlet pipe 33. The liquid storage pipe 61 is connected to the lubricating ring 6. The inner cavity of the ring 6 is connected, and a lubrication hole 62 is opened between the lubrication ring 6 and the inner cavity of the piston tube 3. A sealing plate 63 is slidably connected in the lubrication ring 6, and the sealing plate 63 is aligned with the lubrication hole 62. A sealing spring 631 is fixedly connected between the side wall of the sealing plate 63 and the inner wall of the lubrication ring 6, and there is magnetic repulsion between the side wall of the piston plate 4 and the sealing plate 63; a linkage disk 511 is fixed and connected to the circulation pipe 51, and a linkage impeller 512 is rotatably connected in the linkage disk 511, and the top end of the rotating shaft of the linkage impeller 512 passes through the liquid storage tube 61 and is fixedly connected to the liquid stirring impeller 611.

[0042] By setting the above structure, when the piston plate 4 moves upward to the lubrication ring 6, the magnetic repulsion between the piston plate 4 and the blocking plate 63 will cause the blocking plate 63 to slide toward the side of the compression blocking spring 631, thereby releasing the blockage of the lubrication hole 62. At this time, the water-based lubricant in the lubrication ring 6 will enter the piston tube 3 along the lubrication hole 62, and with the reciprocating movement of the piston plate 4, the water-based lubricant will be evenly applied to the inner wall of the piston tube 3, effectively reducing the friction between the piston plate 4 and the piston tube 3, improving the durability of both, and also improving the efficiency of air compression; and the water-based lubricant can also It can effectively reduce the heat generated by the reciprocating sliding friction between the piston plate 4 and the piston tube 3, reduce the thermal wear between the two, further improve the durability of the two, and ensure the air compression effect; and when the compressed gas enters the air storage tank 2 along the outlet pipe 33, it will drive the pneumatic impeller 521 in the pneumatic disc 52 to rotate, thereby synchronously driving the rotation of the hydraulic impeller 531 in the hydraulic disc 53, thereby driving the coolant in the circulation pipe 51 and the cooling tank 5 to flow, realizing uniform cooling of the piston tube 3, further reducing the thermal wear between the piston plate 4 and the piston tube 3, and ensuring the durability of the piston plate 4 and the piston tube 3. Moreover, when the liquid in the circulation pipe 51 flows, it will also drive the linkage impeller 512 to rotate, thereby driving the stirring impeller 611 in the liquid storage pipe 61 to rotate, thereby stirring the water-based lubricant stored in the liquid storage pipe 61, avoiding the stratification and segregation of the water-based lubricant, so that the components inside the water-based lubricant are evenly dispersed in the liquid storage pipe 61, and improving the use effect of the water-based lubricant.

[0043] Reference Figure 3 , Figure 7 and Figure 8 , wherein a collecting ring 64 is fixedly connected to the bottom of the inner cavity of the piston tube 3, and multiple groups of collecting rings 64 are connected through a series tube 641, a piston groove 65 is opened in the sliding block 46, a pressure plate 651 is slidably connected in the piston groove 65, a return spring 652 is fixedly connected between the top of the pressure plate 651 and the piston groove 65, a liquid guide tube 653 is fixed on the top of the piston groove 65 and connected, the other end of the liquid guide tube 653 is connected to the inner cavity of the series tube 641, and a one-way valve is arranged in the liquid guide tube 653; a drain pipe 654 is fixed and connected to the upper part of the side wall of the piston groove 65, the drain pipe 654 passes through to the outside of the movable frame 1, and a one-way valve is arranged in the drain pipe 654.

[0044] It should be noted that the one-way valve in the liquid guide tube 653 can only allow the lubricant in the collecting ring 64 to enter the piston groove 65 ; the one-way valve in the liquid discharge tube 654 can only allow the lubricant in the piston groove 65 to be discharged along the liquid discharge tube 654 .

[0045] By setting the above structure, the excess water-based lubricant in the piston tube 3 will fall into the collecting ring 64. When the sliding block 46 moves upward, the air pressure plate 651 will gradually return downward under the rebound effect of the return spring 652, thereby generating a suction effect in the piston groove 65, thereby opening the one-way valve in the liquid guide tube 653, so that the water-based lubricant dripping into the collecting ring 64 enters the piston groove 65 along the series tube 641 and the liquid guide tube 653. When the air pressure plate 651 is compressed, the piston The compressed gas in the groove 65 will also open the one-way valve in the drain pipe 654. At this time, the air flow will be discharged along the exhaust pipe 761 and the drain pipe 654 at the same time. When the air compression plate 651 moves to the upper part of the piston groove 65, the water-based lubricant liquid level in the piston groove 65 will first cross the drain pipe 654. At this time, the recovered water-based lubricant will be discharged along the drain pipe 654. This ensures continuous lubrication while effectively reducing the loss of lubricant, reducing the waste of resources, and improving energy saving effects.

[0046] Reference Figure 3 , Figure 8 , Fig.10 and Fig.11 The filter assembly includes a filter disc 7, which is fixedly connected to the air inlet pipe 32. The filter disc 7 is communicated with the inner cavity of the air inlet pipe 32. A rotating shaft 71 is rotatably connected inside the filter disc 7. A filter screen disc 72 is fixedly connected to the rotating shaft 71. The bottom end of the rotating shaft 71 penetrates downward to the bottom of the filter disc 7. A torsion spring 73 is fixedly connected between the outer wall of the rotating shaft 71 and the bottom plate of the filter disc 7. A winding disc 731 is fixedly connected to the bottom end of the rotating shaft 71. A pull rope 732 is fixedly wound around the side wall of the winding disc 731. A guide wheel 7 is fixedly connected to the outer wall of the piston tube 3. 4, the other end of the pull rope 732 is close to the outer wall of the guide wheel 74, penetrates into the compression chamber 41 and is fixedly connected to the linkage plate 43; both sides of the bottom of the filter disc 7 are provided with ash discharge grooves 75, the top of the filter disc 7 is fixedly connected with a back-blowing pipe 751, and the output end of the back-blowing pipe 751 is located at the top of the ash discharge groove 75, and the multiple groups of back-blowing pipes 751 are fixed and connected with an air collecting pipe 76, and the top of the piston groove 65 is fixed and connected with an exhaust pipe 761, the other end of the exhaust pipe 761 is connected with the inner cavity of the air collecting pipe 76, and a one-way valve is arranged in the exhaust pipe 761.

[0047] It should be noted that the one-way valve in the exhaust pipe 761 can only allow the gas in the piston groove 65 to enter the backflush pipe 751 .

[0048] By setting the above structure, when the gas enters the intake pipe 32, it will be filtered by the filter plate 72, so that the dust carried in the gas is filtered out, which effectively improves the cleanliness of the gas and ensures the use effect of the subsequent compressed gas. Moreover, when the end of the linkage plate 43 close to the piston tube 3 is rotated downward, the pull rope 732 will pull the rotating shaft 71 to rotate, so that the filter plate 72 rotates, thereby continuously switching the filtering position of the filter plate 72, effectively improving the filtering effect, and in this process, the torsion spring 73 accumulates force. When the linkage plate 43 is turned to the opposite end, the filter plate 72 will rotate in the opposite direction under the action of the swirling force of the torsion spring 73, so as to realize the filter plate 72 reciprocating rotation, and when the sliding block 46 moves to the bottom of the compression chamber 41, the air compression plate 651 will be compressed into the piston groove 65, thereby compressing the gas in the piston groove 65, and opening the one-way valve in the exhaust pipe 761, so that the gas is transported to the back-blowing pipe 751 along the exhaust pipe 761 and the gas collecting pipe 76, and finally blown to the filter plate 72 along the back-blowing pipe 751, thereby backflushing the filter plate 72, so that the dust attached to the filter plate 72 is blown off and discharged from the filter plate 7 along the dust discharge groove 75, thereby improving the filtering effect of the filter plate 72, effectively ensuring the cleanliness of the compressed gas, avoiding the wear of the internal components of the device by dust, and ensuring the use effect of the compressed air.

[0049] Embodiment 2:

[0050] Reference Figure 1-Figure 11 , which is basically the same as the first embodiment, on the basis of the first embodiment, an air compression method is proposed, and the steps are as follows:

[0051] Step 1: continuously filling the gas storage tank 2 with compressed gas;

[0052] Step 2: filtering the gas flowing through the air intake pipe 32;

[0053] Step 3: Cooling and lubricating the inner wall of the piston tube 3 during the compression process.

[0054] Reference Figure 1-Figure 11When the sliding block 46 moves downward, the linkage plate 43 is pulled to rotate on the side close to the sliding block 46, thereby lifting the side of the linkage plate 43 away from the sliding block 46 upward, thereby pushing the piston plate 4 upward, thereby compressing the gas in the piston tube 3 and opening the one-way valve in the air outlet pipe 33, so that the gas is pressed into the gas storage tank 2 along the air outlet pipe 33, and when the sliding block 46 moves upward, the linkage plate 43 is caused to rotate in the opposite direction, thereby pulling the piston plate 4 downward through the push-pull rod 44, thereby generating a suction effect in the piston tube 3, thereby opening the one-way valve in the air inlet pipe 32, so that the external gas is sucked into the piston tube 3, and so on and so forth, gas will be continuously filled into the gas storage tank 2, thereby increasing the air pressure in the gas storage tank 2, thereby completing the air compression.

[0055] When the gas enters the intake pipe 32, it will be filtered by the filter plate 72, so that the dust carried in the gas is filtered out, which effectively improves the cleanliness of the gas and ensures the use effect of the subsequent compressed gas. Moreover, when the end of the linkage plate 43 close to the piston tube 3 rotates downward, the pull rope 732 will pull the rotating shaft 71 to rotate, so that the filter plate 72 rotates, thereby continuously switching the filtering position of the filter plate 72, effectively improving the filtering effect, and in this process, the torsion spring 73 accumulates force. When the linkage plate 43 is turned to the opposite end, the filter plate 72 will rotate in the opposite direction under the action of the swirling force of the torsion spring 73. , thereby realizing the reciprocating rotation of the filter disc 72, and when the sliding block 46 moves to the bottom of the compression chamber 41, the air pressure plate 651 will be compressed into the piston groove 65, thereby compressing the gas in the piston groove 65, and opening the one-way valve in the exhaust pipe 761, so that the gas is transported to the backblowing pipe 751 along the exhaust pipe 761 and the gas collecting pipe 76, and finally blown toward the filter disc 72 along the backblowing pipe 751, thereby recoil-flushing the filter disc 72, so that the dust attached to the filter disc 72 is blown off and discharged from the filter disc 7 along the dust discharge groove 75, thereby improving the filtering effect of the filter disc 72 and effectively ensuring the cleanliness of the compressed gas.

[0056] When the piston plate 4 moves upward to the lubrication ring 6, the magnetic repulsion between the piston plate 4 and the sealing plate 63 will cause the sealing plate 63 to slide toward the side of the compression sealing spring 631, thereby releasing the blockage of the lubrication hole 62. At this time, the water-based lubricant in the lubrication ring 6 will enter the piston tube 3 along the lubrication hole 62, and with the reciprocating movement of the piston plate 4, the water-based lubricant will be evenly applied to the inner wall of the piston tube 3, effectively reducing the friction between the piston plate 4 and the piston tube 3, improving the durability of both, and also improving the efficiency of air compression; and the water-based lubricant can also effectively reduce the heat generated by the reciprocating sliding friction between the piston plate 4 and the piston tube 3, reduce the thermal wear between the two, and further improve the durability of both.

[0057] When the compressed gas enters the gas storage tank 2 along the gas outlet pipe 33, it will push the pneumatic impeller 521 in the pneumatic disc 52 to rotate, thereby synchronously driving the rotation of the hydraulic impeller 531 in the hydraulic disc 53, thereby driving the coolant in the circulation pipe 51 and the cooling tank 5 to flow, achieving uniform cooling of the piston tube 3, further reducing the thermal wear between the piston plate 4 and the piston tube 3, and ensuring the durability of the piston plate 4 and the piston tube 3. Moreover, when the liquid in the circulation pipe 51 flows, it will also push the linkage impeller 512 to rotate, thereby driving the stirring impeller 611 in the liquid storage pipe 61 to rotate, thereby stirring the water-based lubricant stored in the liquid storage pipe 61, avoiding the stratification and segregation of the water-based lubricant, so that the components inside the water-based lubricant are evenly dispersed in the liquid storage pipe 61, and improving the use effect of the water-based lubricant. The excess water-based lubricant in the piston tube 3 will fall into the collecting ring 64. When the sliding block 46 moves upward, the return spring 652 will gradually return the air pressure plate 651 downward, thereby generating a suction effect in the piston groove 65, thereby opening the one-way valve in the liquid guide tube 653, so that the water-based lubricant dripping into the collecting ring 64 will flow into the piston groove 65 along the series tube 641 and the liquid guide tube 653. When the air pressure plate 651 is compressed, the piston groove 65 The compressed gas will also open the one-way valve in the drain pipe 654. At this time, the air flow will be discharged along the exhaust pipe 761 and the drain pipe 654 at the same time. When the air compression plate 651 moves to the upper part of the piston groove 65, the water-based lubricant liquid level in the piston groove 65 will first cross the drain pipe 654. At this time, the recovered water-based lubricant will be discharged along the drain pipe 654. This ensures continuous lubrication while effectively reducing the loss of lubricant, reducing the waste of resources, and improving energy saving effects.
