Description

Technical Field

[0001] This invention relates to the field of air compressor technology, specifically to an air compressor that can reduce the internal piston temperature. Background Technology

[0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston type, rotary vane type, or rotary screw type. An air compressor is a device that uses the rotation of fan blades to drive the piston, which in turn moves the gas and stores it inside a housing.

[0003] In existing technologies, air compressors typically rely on the reciprocating motion of a piston within a cylinder to compress air during operation. While cooling components such as copper pipes can cool the compressed air in existing two-stage air compressor structures, the heat inside the piston is difficult to dissipate effectively, hindering cooling. As the equipment continues to operate, the internal temperature of the piston gradually increases, potentially deteriorating its working environment. The propyne piston is often made of lightweight materials like aluminum alloy, which are prone to thermal deformation under prolonged high temperatures. This alters the fit between the piston and cylinder, causing the piston's trajectory to deviate, leading to abnormal mechanical impacts and vibrations. Vibration not only exacerbates wear on moving parts such as pistons, connecting rods, and bearings but can also reduce valve sealing performance, loosen pipe connections, and cause poor contact in electrical components. This accelerates the aging process of the entire machine, affecting its operational stability and service life, and is detrimental to long-term equipment use. Summary of the Invention

The first water suction pipe and the second water suction pipe are connected to the air compressor body through a fixing bracket. The inner walls of the first water suction pipe and the second water suction pipe are slidably connected with tie rods, and the two sets of tie rods are in opposite directions.

[0007] Preferably, one end of the cooling pipe is connected to the bottom end of the first water pumping pipe, and the other end of the cooling pipe is connected to the top end of the second water pumping pipe. A first water inlet is provided at the connection between the top end of the first water pumping pipe and the cooling pipe. A first drain outlet is provided on the side wall of the top end of the first water pumping pipe. A second drain outlet is provided at the bottom end of the second water pumping pipe. A second water inlet is provided on the side wall of the bottom end of the second water pumping pipe. A connecting pipe is provided between the first drain outlet and the second water inlet.

[0008] Preferably, the outer walls at both ends of the air compressor body are rotatably connected to rotating plates, and a connecting rod is rotatably connected to the surface of the rotating plate away from the axis. A transmission rod is connected to the end of the connecting rod away from the rotating plate. The transmission rod is located between the first water pumping pipe and the second water pumping pipe, and both sets of tie rods are connected to the transmission rod.

[0009] Preferably, an electric telescopic rod is provided between the two sets of fans and installed on the surface of the air compressor body. Both ends of the electric telescopic rod are connected to L-shaped moving blocks. The fans are connected to the upper surface of the L-shaped moving blocks. The side surface of the two sets of fans away from the electric telescopic rod is connected to an air guide cover.

[0010] Preferably, the vibration damping component includes two sets of pressure plates connected to the mounting plate, a telescopic block connected to the center of the lower surface of the two sets of pressure plates, two sets of inclined blocks symmetrically connected to the lower surface of the two sets of pressure plates, a push block attached to one side surface of the two sets of inclined blocks, and a damping rod connected to the side surface of the push block away from the inclined block.

[0011] Preferably, damping springs are provided in the cavities of the inner walls of the telescopic block and the inner walls of the damping rod, the damping rod is filled with oil, a pulley is provided at the contact position between the inclined block and the push block, and a groove matching the pulley is opened at the contact position between the push block and the surface of the inclined block.

[0012] Preferably, two sets of magnetic blocks are symmetrically arranged on the upper surface of the pressure plate, and electromagnets are installed on the lower surface of the mounting plate at positions corresponding to the magnetic blocks, with the magnetic poles of the magnetic blocks and electromagnets being the same. A sensor and a controller are installed on the surface of the mounting plate.

[0013] In summary, the present invention has the following main beneficial effects:

[0014] 1. This invention uses the operation of the first and second water pumping pipes to drive the cooling medium to circulate inside the cooling pipe, contact pipe, and flow pipe, thereby facilitating continuous and stable cooling of the piston's interior during the operation of the air compressor body. The heat generated by the piston during reciprocating motion can be quickly transferred to the cooling medium through the contact pipe. Under the action of the first and second water pumping pipes, the cooling medium circulates between the flow pipe and the cooling pipe. At the same time, through the synergistic action of the heat dissipation fins and the fan, the cooling medium inside the cooling pipe is continuously cooled, thereby effectively reducing the temperature inside the piston. The cooling medium is continuously cooled during circulation and flows back into the contact pipe, thereby facilitating continuous cooling of the piston's inner wall and preventing piston thermal deformation caused by heat accumulation. When the piston's movement frequency increases, with the cooperation of the sensor and controller, the electric telescopic rod and L-shaped moving block drive the fan to move, automatically adjusting the fan position. Then, the airflow is directed more concentratedly towards the cooling pipe through the air guide shroud, further improving the heat dissipation efficiency.

[0015] 2. This invention uses a vibration damping component to dampen the vibration of the air compressor body. When the air compressor body vibrates, the pressure plate moves under force, causing the inclined block to press against the push block. The push block pushes the damping rod to move to both ends. Since both the damping rod and the telescopic block are equipped with damping springs, and the damping rod is filled with oil, the vibration generated by the air compressor body can be effectively mitigated through the synergistic effect of the damping springs and oil, preventing the vibration from being transmitted to the air compressor body. At the same time, the magnetic blocks on the pressure plate and the electromagnets on the mounting plate work together to generate magnetic repulsion force using the principle of "like poles repel each other," further offsetting the vibration and improving the damping effect on the air compressor body. This reduces the vibration amplitude of the air compressor body to a certain extent, reduces vibration damage, improves the stability of the air compressor body's operation, extends the service life of the air compressor body, and enhances the overall safety of the air compressor body.

[0028] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structure, features, and effects of the present invention.

[0029] An air compressor that can reduce the temperature of the internal piston, such as Figure 1 - Figure 11As shown, the compressor includes an air compressor body 1. A mounting plate 11 is provided on the lower surface of the air compressor body 1. Inside the air compressor body 1 are two sets of reciprocating pistons. Air enters through the inlet and is first compressed by the first piston. After prolonged use, the temperature inside the first piston chamber becomes high. After compression by the first piston, the air is then compressed a second time by the second piston. When the air enters the second piston through a copper pipe, it can cool the air to a certain extent. Therefore, the inner wall temperature of the second piston is lower than that of the first piston. Cooling components are provided on both sides of the air compressor body 1 to dissipate heat from the inner walls of the pistons. The cooling medium in the cooling components cools the first piston, then the second piston, and then re-enters the second piston. This cycle continues, cooling the two sets of pistons. The inner wall of the compressor is cooled, which can reduce the piston temperature to a certain extent. The bottom of the mounting plate 11 is provided with two sets of vibration damping components to dampen the vibration of the air compressor body 1. The air compressor body 1 has a cavity for piston movement. The cooling components include contact pipes 22 that fit against the inner wall of the cavity. After the cooling medium passes through the contact pipes 22, it can remove part of the temperature inside the piston, thus facilitating the cooling of the piston. One end of each of the two sets of contact pipes 22 is connected to a flow pipe 21. The flow pipe 21 facilitates the circulation of the cooling medium. The other end of each of the two sets of contact pipes 22 is connected to a cooling pipe 23. The outer wall of the cooling pipe 23 is provided with heat dissipation fins 231, and two sets of fans 29 are provided between the two sets of pistons. The fans 29 are located on one side of the heat dissipation fins 231. The cooling medium inside the cooling pipe 23 can be dissipated by the heat dissipation fins 231 and the fans 29.

[0030] See Figure 5 , Figure 7 , Figure 8 , Figure 11 It can be seen that a first water suction pipe 24 and a second water suction pipe 25 are provided on the side of the cooling pipe 23 away from the fan 29. The first water suction pipe 24 and the second water suction pipe 25 are connected to the air compressor body 1 through a fixing bracket. The inner walls of the first water suction pipe 24 and the second water suction pipe 25 are slidably connected with pull rods, and the two sets of pull rods are in opposite directions. With the arrangement of the first water suction pipe 24 and the second water suction pipe 25, when the pull rods move inside the first water suction pipe 24 and the second water suction pipe 25, the cooling medium can be driven to flow, thereby facilitating the circulation of the cooling medium.

[0031] See Figure 5 , Figure 7 , Figure 8It is known that one end of the cooling pipe 23 is connected to the bottom end of the first water pumping pipe 24, and the other end of the cooling pipe 23 is connected to the top end of the second water pumping pipe 25. A first water inlet is provided at the connection between the top end of the first water pumping pipe 24 and the cooling pipe 23. A first water outlet is provided on the side wall of the top end of the first water pumping pipe 24. A second water outlet is provided at the bottom end of the second water pumping pipe 25. A second water inlet is provided on the side wall of the bottom end of the second water pumping pipe 25. A connecting pipe is connected between the first water outlet and the second water inlet. A one-way valve is provided on the inner wall of the first water inlet, the second water inlet, the first water outlet, and the second water outlet. When the pull rod moves downward, the cooling medium passes through the first water inlet, the second water inlet, the first water outlet, and the second water outlet. The water inlet enters the first water pumping pipe 24. The one-way valves at the first drain outlet and the second water inlet are closed, while the one-way valves at the first water inlet and the second drain outlet are open. At this time, the cooling medium inside the cooling pipe 23 enters the first water pumping pipe 24 through the first water inlet, and the cooling medium inside the second water pumping pipe 25 enters the cooling pipe 23 through the second drain outlet. When the lever is reset, the one-way valves at the first water inlet and the second drain outlet are closed. At this time, the cooling medium inside the first water pumping pipe 24 enters the second water pumping pipe 25 through the first drain outlet and the connecting pipe, thus completing the circulation operation of the cooling medium.

[0032] See Figure 4 , Figure 6 , Figure 7 It is known that rotating plates 27 are rotatably connected to the outer walls of both ends of the air compressor body 1. A connecting rod 271 is rotatably connected to the surface of the rotating plate 27 away from the axis. A transmission rod 26 is connected to the end of the connecting rod 271 away from the rotating plate 27. The transmission rod 26 is located between the first water suction pipe 24 and the second water suction pipe 25. Both sets of pull rods are connected to the transmission rod 26. The piston drive component inside the air compressor body 1 is connected to a shaft. One end of the shaft extends to the outside of the air compressor body 1 and is connected to the rotating plate 27. When the piston moves, the rotating plate 27 rotates synchronously under the action of the shaft, which facilitates the connecting rod 271 to pull the transmission rod 26 to make up-down reciprocating motion. In turn, under the action of the transmission rod 26, the pull rod is driven to move up and down reciprocally, which drives the cooling medium to circulate.

[0033] See Figure 2 , Figure 3 , Figure 4 , Figure 9 , Figure 10 It can be seen that two sets of magnetic blocks 36 are symmetrically arranged on the upper surface of the pressure plate 31. Electromagnets are installed on the lower surface of the mounting plate 11 at the corresponding positions of the magnetic blocks 36. The magnetic blocks 36 and the electromagnets have the same magnetic poles. A sensor and a controller are installed on the surface of the mounting plate 11. When the sensor senses that the piston speed is getting faster, the current of the electromagnet can be increased through the controller to enhance the magnetism of the electromagnet, thereby increasing the magnetic repulsion between the electromagnet and the magnetic blocks 36. At the same time, the electric telescopic rod 28 can be activated under the action of the controller. The electric telescopic rod 28, together with the L-shaped moving block 281, drives the fan 29 to move closer to the cooling pipe 23.

[0034] An electric telescopic rod 28 is installed on the surface of the air compressor body 1 between the two sets of fans 29. Both ends of the electric telescopic rod 28 are connected to L-shaped moving blocks 281. The fans 29 are connected to the upper surface of the L-shaped moving blocks 281. The side surface of the two sets of fans 29 away from the electric telescopic rod 28 is connected to the air guide shroud. When the fans 29 move toward the cooling pipe 23, the airflow blown by the fans 29 is guided by the air guide shroud, thereby improving the heat dissipation efficiency of the cooling pipe 23.

[0035] See Figure 2 , Figure 9 , Figure 10 It is known that the vibration damping component includes two sets of pressure plates 31 connected to the mounting plate 11. A telescopic block 32 is connected to the center of the lower surface of the two sets of pressure plates 31. Two sets of inclined blocks 33 are symmetrically connected to the lower surface of the two sets of pressure plates 31. A push block 34 is attached to one side surface of the two sets of inclined blocks 33. A damping rod 35 is connected to the side surface of the push block 34 away from the inclined block 33. When the air compressor body 1 starts and vibrates, the pressure plate 31 will squeeze the telescopic block 32. At this time, the inclined block 33 will push the push block 34 to move. When the push block 34 moves, it will squeeze the damping rod 35.

[0036] Both the inner wall of the telescopic block 32 and the inner wall cavity of the damping rod 35 are equipped with damping springs. The damping rod 35 is filled with oil. With the cooperation of the damping springs and the oil, the air compressor body 1 can be damped. A pulley is provided at the contact position between the inclined block 33 and the push block 34. A groove matching the pulley is opened at the contact position between the push block 34 and the surface of the inclined block 33. The setting of the pulley and the groove facilitates the guidance of the movement direction of the inclined block 33 and the push block 34.

[0037] The working principle of the present invention is as follows: During the operation of the air compressor body 1, the internal piston will continuously generate heat when it reciprocates. During the movement of the piston, the rotating plate 27 is driven to rotate synchronously. When the rotating plate 27 rotates, the transmission rod 26 is driven to reciprocate up and down through the connecting rod 271. When the transmission rod 26 moves, it synchronously drives the pull rod to reciprocate inside the first water pipe 24 and the second water pipe 25.

[0038] When the pull rod inside the first water-drawing pipe 24 moves downward under the force of the transmission rod 26, the one-way valve of the first water inlet at the top of the first water-drawing pipe 24 opens, and the cooling medium inside the cooling pipe 23 enters the first water-drawing pipe 24. At this time, the one-way valve of the first drain outlet on the side wall at the top of the first water-drawing pipe 24 remains closed. At the same time, the pull rod inside the second water-drawing pipe 25 moves downward synchronously under the force of the transmission rod 26, and the one-way valve of the second drain outlet at the bottom of the second water-drawing pipe 25 opens, and the cooling medium inside it is discharged into the cooling pipe 23.

[0039] When the transmission rod 26 is reset, the pull rod inside the first water pumping pipe 24 moves upward, squeezing the cooling medium inside. At the same time, the pull rod inside the second water pumping pipe 25 moves upward synchronously. At this time, the one-way valve of the first drain port on the side wall of the first water pumping pipe 24 opens, and the one-way valve of the second inlet on the side wall of the second water pumping pipe 25 opens synchronously. The cooling medium in the first water pumping pipe 24 enters the second water pumping pipe 25 through the connecting pipe, thereby realizing the circulation of the cooling medium.

[0040] After the cooling medium inside the second water intake pipe 25 enters the cooling pipe 23, the heat dissipation fins 231 on the outer wall of the cooling pipe 23 dissipate heat from the cooling medium. The cooled cooling medium then enters a set of contact pipes 22, which cools the inner wall of a set of pistons. The cooled cooling medium then enters the flow pipe 21 and enters another set of contact pipes 22, which cools the inner wall of another set of pistons. After cooling, the cooling medium re-enters the cooling pipe 23 for heat dissipation. During the circulation of the cooling medium, the fan 29 continuously blows air onto the cooling pipe 23, which, together with the heat dissipation fins 231, further improves the heat dissipation efficiency of the cooling medium in the cooling pipe 23. This continuously cools the inner walls of both sets of pistons, which helps to reduce the internal temperature of the pistons and prevents the pistons from deforming due to excessive temperature. This, in turn, helps to extend the service life of the air compressor body 1.

[0041] During operation, the air compressor body 1 will vibrate. When vibration occurs, the pressure plate 31 moves under the force of the air compressor body 1, and the inclined block 33 presses the push block 34 to one end. When the push block 34 moves, it presses the damping rod 35. Since the damping rod 35 and the telescopic block 32 are both equipped with damping springs, and the damping rod 35 is filled with oil, it is convenient to work together with the oil to dampen the vibration of the air compressor body 1.

[0042] Two sets of magnetic blocks 36 are installed on the upper surface of the pressure plate 31. An electromagnet is installed on the lower surface of the mounting plate 11 at the position corresponding to the magnetic blocks 36. After the air compressor body 1 is started, the electromagnet is automatically energized. Since the electromagnet and the magnetic blocks 36 have the same magnetic poles, the principle of "like poles repel each other" between the magnetic poles can be used to generate a magnetic repulsive force to further dampen the air compressor body 1, thereby improving the overall damping effect.

[0043] When the piston movement frequency inside the air compressor body 1 increases, the vibration frequency of the air compressor body 1 also increases. At this time, the time interval between continuous compression of air inside the piston is shortened, and the heat cannot be fully dissipated, so the gas temperature rises accordingly. When the sensor detects that the speed of the motor driving the piston movement has increased, under the control of the controller, the electric telescopic rod 28 drives the L-shaped moving block 281 to push the fan 29 closer to the cooling pipe 23. At the same time, the air guide shroud forces the dispersed airflow blown out by the fan 29 to gather and guide it to the cooling pipe 23, thereby improving the heat dissipation efficiency of the cooling pipe 23.
