Technical Field

[0001] This invention relates to the field of air compressor technology, specifically to a hollow eccentric pin water-cooled oil-free scroll air compressor. Background Technology

[0002] With the improvement of industrial manufacturing technology, many industries have increasingly broader and higher demands for compressed air applications. At the same time, environmental protection indicators have also put forward new requirements for the green application of compressed air, and the market demand for oil-free air compressors is gradually increasing.

[0003] Traditional air compressors have long faced problems such as cumulative energy consumption (cooling / lubrication requires independent power sources), overheating risk, local temperature control failure of scroll components, lubrication interruption (reliant on manual maintenance and prone to sudden oil shortages), high maintenance costs (frequent replacement of coolant / lubricating oil and consumables), and system fragility (numerous electronic control failures, numerous sealing points and high leakage rate). In essence, these problems are caused by fragmented functional modules and external dependence, resulting in low energy efficiency, poor reliability and heavy maintenance burden. Summary of the Invention

The outer wall of the end ring sleeve is provided with an expanded diameter annular groove, and the input channels extend around to the expanded diameter annular groove. A cooling liquid storage pan is provided on the outside of the end ring sleeve, and the outer wall of the cooling liquid storage pan is provided with heat-conducting rings. The inner side of the expanded diameter annular groove is connected to the inner input end of the cooling liquid storage pan through circumferentially distributed output channels. The output end of the outer ring sidewall of the cooling liquid storage pan is provided with circumferentially distributed return pipes, and while the return pipes are placed on the outside, their output ends are connected to the output end of the return channel.

[0009] Preferably, the central transmission mechanism includes a transmission main shaft, which is embedded and rotates inside the center of the main tank, while an eccentric guide wheel is fixed at one end of the transmission main shaft facing the transfer kit mechanism, and the eccentric guide wheel is embedded and rotates inside the liquid storage ring, and a trapezoidal pusher is disposed opposite to the side wall of the eccentric guide wheel.

[0011] Preferably, the lubrication drive mechanism includes a forward pusher can, which slides along the inner wall of the main tank and is sleeved on the outside of the transmission main shaft.

[0015] This invention provides a hollow eccentric pin water-cooled oil-free scroll air compressor. It has the following beneficial effects: 1.

[0016] 2. This invention features a closed-loop self-regulating cooling system: the coolant release is directly controlled by the displacement amplitude of the forward push tank (i.e., the spindle speed). At high speeds, the compression amount increases, and the flow rate automatically increases. The coolant flows through the surface of the vortex assembly (moving / static vortex channels, deflecting disk) to directly absorb the heat of compression. Then, it flows through the heat-conducting ring of the cooling liquid storage pan for efficient heat dissipation. The coolant is fully recovered through the return pipe and reabsorbed and stored by the sponge block, resulting in zero medium loss.

[0017] 3. This invention has a mechanical synchronous coordination effect: the spindle speed synchronously controls the compression frequency, lubrication frequency and coolant flow rate, and the three are strictly proportionally synchronized. The coating ball continuously contacts the spindle during the reciprocating motion of the can, ensuring uninterrupted lubrication. The reset snap ring returns the can to its original position, and the sponge expands to refill the liquid, preparing for the next cycle. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 - Appendix Figure 2This invention provides a hollow eccentric pin water-cooled oil-free scroll air compressor, comprising: a main tank 1 for fixing the structure of the hollow eccentric pin water-cooled oil-free scroll air compressor. The main tank 1 is a cylindrical structure with one side opening. As the core fixing structure, the main tank 1 provides a stable installation foundation to ensure the overall smooth operation of the equipment. When the equipment is in operation, the main tank 1 houses the transfer kit 3, the air compressor kit 4, the central transmission mechanism 5, and the lubrication drive mechanism 7, preventing the vibration of each component from interfering with the internal operation. Its cylindrical structure design maintains the sealing performance on the one hand to prevent the intrusion of external foreign objects, and on the other hand to support the dynamic interaction of the internal mechanisms. When the drive motor 2 starts, the main tank 1 bears the stress of torque transmission to ensure the stability of the rotation trajectory of the central transmission mechanism 5, thereby avoiding displacement deviation from affecting the compression efficiency of the scroll air compressor mechanism 6. The fixing function of the main tank 1 indirectly supports the coolant circulation and lubrication system, without directly participating in fluid or mechanical actions. Please see the appendix Figure 1 - Appendix Figure 2 The drive motor 2 is located in the main tank 1 and is used to generate the rotational torque required for the vortex air compressor. The drive motor 2 is set on the side wall of the main tank 1. The drive motor 2 generates continuous rotational torque by inputting electrical energy and directly transmits it to the transmission main shaft 51 of the central transmission mechanism 5. This torque is the initial driving force source for the operation of the equipment and is responsible for driving the eccentric swing action of the vortex air compressor mechanism 6. During the start-up phase, the output shaft of the drive motor 2 rotates synchronously with the transmission main shaft 51 to ensure that the contact motion between the moving vortex channel 62 and the stationary vortex channel 63 continues. Its power output matches the load requirements: it increases the compression frequency at high speed and reduces mechanical stress at low speed. The stability of the drive motor 2 directly affects the efficiency of the entire equipment and prevents the reciprocating motion of the lubrication drive mechanism 7 from being interrupted due to torque fluctuations. Please see the appendix Figure 3 - Appendix Figure 6 The transfer kit mechanism 3 is located in the main tank 1 and is used to form a sealed guiding space for the eccentric displacement of the moving vortex, and to store and output vortex coolant to cool the moving vortex. The transfer kit mechanism 3 is attached to one side opening of the main tank 1. The transfer kit mechanism 3 is mainly responsible for forming a sealed guiding space for the eccentric displacement of the moving vortex, and storing and outputting coolant to cool the moving vortex. When the equipment is running, the reciprocating motion of the lubrication drive mechanism 7 pushes the internal structure of the transfer kit mechanism 3 to release the stored coolant. The coolant is output to the transfer channel 34 through the squeezing action of the annular sponge block 33 and flows to the air compressor kit 4 to cool the hot surface. At the same time, the return channel 35 receives the cooled coolant backflow to complete the closed loop circulation. The transfer kit mechanism 3 ensures that there is no leakage in the vortex movement through the sealed space. Its coolant management mechanism directly relies on external mechanical drive to maintain heat exchange efficiency. Please see the appendix Figure 5 - Appendix Figure 6The transfer assembly 3 includes a middle ring 31, which is fixed to the side of the main tank 1 away from the drive motor 2. A liquid storage ring 32 is embedded in the inner wall of the middle ring 31. An annular sponge block 33 is embedded and fitted to the inner wall of the liquid storage ring 32. A transfer channel 34 is embedded around the outer wall of the liquid storage ring 32 facing the air compressor assembly 4, and its output end extends to the air compressor assembly 4. A return channel 35 is surrounded around the outer ring of the middle ring 31, and its output end penetrates the side wall of the liquid storage ring 32. The middle ring 31 is fixed to the main tank 1. The structure provides support; the reservoir ring 32 stores coolant and releases the liquid under pressure under the action of the lubrication drive mechanism 7; the annular sponge block 33 absorbs and releases coolant, and the fluid is output by compression; the transfer channel 34 transmits coolant to the air compressor kit mechanism 4 and guides the flow path; the return channel 35 receives the returned coolant and returns it to the reservoir ring 32. These sub-components work together: the compression of the annular sponge block 33 releases coolant, and the transfer channel 34 and the return channel 35 form a circulation channel to ensure that the coolant continuously contacts the vortex surface for heat dissipation without the intervention of external pumps.

[0022] Please see the appendix Figure 4 - Appendix Figure 8 The air compressor assembly 4 is located in the transfer assembly 3. It works with the middle ring 31, the transfer channel 34 and the return channel 35 to form a sealed stationary space for the static vortex and to receive and transport vortex coolant to cool the static vortex. The air compressor assembly 4 is fitted and sealed to the outside of the transfer assembly 3. The air compressor assembly 4 forms a sealed stationary space for the static vortex and receives and transports coolant to cool the static vortex. During equipment operation, coolant flows from the transfer assembly 3 into the air compressor assembly 4 and absorbs heat by contacting the surface of the static vortex channel 63 through the input channel. The mechanism uses the sealing design of the end ring 41 to maintain the compression space. At the same time, the coolant reduces the heat load during the flow. The pipeline structure of the air compressor assembly 4 ensures that the coolant is evenly distributed and accelerates heat dissipation through external exposure during the return stage. Its working principle focuses on thermal management: after absorbing heat, the coolant flows to the cooling reservoir 43 for cooling and supports the continuous operation of the vortex air compressor assembly 6. Please see the appendix Figure 7 - Appendix Figure 8The air compressor assembly 4 includes an end ring 41, which is fitted and fixed to the outside of the middle ring 31, forming an annular air compressor space. The outer ring sidewall of the end ring 41 has an air inlet structure, and the inner cavity sidewall of the end ring 41 has circumferentially distributed input channels adjacent to the output end of the transfer channel 34. An expanded diameter annular groove 42 is provided inside the outer wall of the end ring 41, and the input channels extend around and around the expanded diameter annular groove 42. A cooling liquid reservoir 43 is provided on the outer side of the end ring 41, and heat-conducting rings are distributed on the outer wall of the cooling liquid reservoir 43. The inner side of the expanded diameter annular groove 42 connects to the inner input end of the cooling liquid reservoir 43 through circumferentially distributed output channels. A circularly distributed return pipe 44 is installed at the output end of the outer ring sidewall. While the return pipe 44 is placed on the outside, its output end is connected to the output end of the return channel 35. The end ring sleeve 41 forms a static vortex sealing space. The input channel receives the coolant and guides it to the expansion annular groove 42. The expansion annular groove 42 increases the flow area of ​​the coolant and improves the heat exchange efficiency. The cooling liquid reservoir 43 dissipates heat through the heat conduction ring, reducing the temperature of the coolant. The return pipe 44 transports the cooled coolant back to the transfer kit mechanism 3. These sub-components work together: the coolant enters the expansion annular groove 42 from the input channel, then flows into the cooling liquid reservoir 43 through the output channel for heat dissipation, and finally returns through the return pipe 44. The principle ensures that the coolant circulates and dissipates heat in the static vortex area without energy loss.

[0023] Please see the appendix Figure 4 - Appendix Figure 6 The central transmission mechanism 5 is located in the main tank 1 and works with the middle section ring 31, the liquid storage ring 32 and the annular sponge block 33 to transmit the eccentric rotation torque. The central transmission mechanism 5 is embedded in the main tank 1 and transmits the rotation torque of the drive motor 2 to the vortex air compressor mechanism 6 to achieve eccentric motion. During equipment operation, the rotation of the transmission main shaft 51 drives the eccentric guide wheel 52 to swing, driving the eccentric moving disk 61 to perform vortex compression. At the same time, the rotation of the trapezoidal pusher 53 triggers the reciprocating movement of the lubrication drive mechanism 7. The transmission process of the central transmission mechanism 5 ensures efficient torque conversion: the speed of the transmission main shaft 51 directly controls the compression frequency and lubrication action synchronously. Its working principle is based on mechanical transmission, which supports the core compression and auxiliary system drive without interruption. Please see the appendix Figure 5 - Appendix Figure 6The central transmission mechanism 5 includes a transmission main shaft 51, which is embedded and rotates inside the center of the main tank 1. An eccentric guide wheel 52 is fixed to one end of the transmission main shaft 51 facing the transfer assembly mechanism 3, and is embedded and rotates inside the liquid storage ring 32. A trapezoidal pusher 53 is positioned opposite the side wall of the eccentric guide wheel 52. The transmission main shaft 51 transmits torque to drive the entire mechanism to rotate. The eccentric guide wheel 52 converts the rotation into eccentric oscillation, which drives the eccentric moving plate 61 to move. The trapezoidal pusher 53 pushes the trapezoidal top platform 73 of the lubrication drive mechanism 7 as it rotates, triggering reciprocating movement. These sub-components work together: the input of the transmission main shaft 51 drives the eccentric guide wheel 52 to generate a vortex motion, and the protruding structure of the trapezoidal pusher 53 pushes periodically to realize the mechanical drive of coolant and lubricant. Its principle ensures efficient power conversion without additional control elements. Please see the appendix Figure 3 - Appendix Figure 5 The input shaft end of the transmission spindle 51 is connected to the output end of the drive motor 2. The input shaft end of the transmission spindle 51 is directly connected to the output end of the drive motor 2 to achieve seamless torque transmission. When the equipment starts, the rotational force of the drive motor 2 is input to the transmission spindle 51 through this connection point to drive it to rotate continuously. This connection ensures that the power transmission is not delayed and supports the synchronous action of the eccentric guide wheel 52 and the trapezoidal push table 53 of the central transmission mechanism 5. Its working principle focuses on efficient energy transmission: the input torque is directly converted into vortex compression and lubrication drive without intermediate loss.

[0024] Please see the appendix Figure 3 - Appendix Figure 8 The vortex air compressor mechanism 6 is located in the air compressor kit mechanism 4. It works with the middle ring sleeve 31 and the end ring sleeve 41 to form the dynamic and static vortices required for air compression. The vortex air compressor mechanism 6 is embedded in the transfer kit mechanism 3. The vortex air compressor mechanism 6 forms dynamic and static vortices to perform air compression. When the equipment is running, the dynamic vortex channel 62 swings eccentrically with the biased moving plate 61 and comes into contact with the static vortex channel 63 to generate compression force. Air is drawn in from the air inlet, compressed in the vortex motion, and discharged through the output air pipe 64. The working principle of this mechanism depends on the drive of the central transmission mechanism 5: the eccentric motion generates continuous compression, the coolant flow manages the heat load, its independent function realizes efficient gas processing, and it has an oil-free lubrication design. Please see the appendix Figure 3 - Appendix Figure 8The vortex air compressor mechanism 6 includes a deflecting moving disk 61 and a stationary vortex channel 63. The deflecting moving disk 61 is attached to the outer wall of the liquid storage ring 32 and swings eccentrically. The rotating end of the deflecting moving disk 61 is fixed to the centrifugal end of the eccentric guide wheel 52. The moving vortex channel 62 is fixed to the outer side of the deflecting moving disk 61, and the stationary vortex channel 63 is fixed to the inner wall of the end ring 41. The stationary vortex channel 63 and the moving vortex channel 62 are attached to each other inside the end ring 41. The deflecting moving disk 61 swings eccentrically, driving the moving vortex channel 62 to move. The moving vortex channel 62 and the stationary vortex channel 63 are in contact with the compressed air. The stationary vortex channel 63 is fixed to provide a reaction force. The output air pipe 64 discharges the compressed gas. These sub-components work together: the swing of the deflecting moving disk 61 causes the moving vortex channel 62 to generate a vortex trajectory. The compressed air accumulates in the center of the stationary vortex channel 63 and is released through the output air pipe 64. The principle ensures that the compression process is continuous and the coolant contacts the surface to dissipate heat. Please see the appendix Figure 7 - Appendix Figure 8 An output air pipe 64 is located at the center of the static vortex channel 63, and compressed air is discharged through the output air pipe 64. The output air pipe 64 is located at the center of the static vortex channel 63 and is responsible for discharging compressed air. During the vortex compression process, the air is squeezed to the central area of ​​the static vortex channel 63 and continuously output through the output air pipe 64. The pipe is designed to maintain unidirectional airflow to prevent backflow from interfering with compression efficiency. Its working principle is independent: as an exhaust channel, it directly supports the gas handling function of the vortex air compressor mechanism 6 without any additional drive mechanism.

[0025] Please see the appendix Figure 9 - Appendix Figure 10 The lubrication drive mechanism 7 is located in the main tank 1. It works in conjunction with the transmission main shaft 51, eccentric guide wheel 52, trapezoidal pusher 53, and the continuously rotating vortex to generate the hydraulic thrust for coolant circulation and to output lubricant during transmission. The lubrication drive mechanism 7 is embedded and movable in the main tank 1. The lubrication drive mechanism 7 generates the hydraulic thrust for coolant circulation and outputs lubricant. When the equipment is running, the trapezoidal pusher 53 of the central transmission mechanism 5 pushes the mechanism, triggering the forward pusher tank 71 to move back and forth. This displacement squeezes the coolant storage structure of the transfer kit mechanism 3, driving the coolant to flow. At the same time, the lubricant in the conical liquid storage tank 75 is applied to the transmission main shaft 51. Its working principle is based on mechanical reciprocating: displacement generates fluid pumping force and lubrication action, supporting thermal management and friction reduction. Please see the appendix Figure 9 - Appendix Figure 10The lubrication drive mechanism 7 includes a forward pusher 71, which slides along the inner wall of the main tank 1 and is sleeved on the outside of the transmission main shaft 51. The forward pusher 71 and the inner side wall of the main tank 1 are limited and pushed by a reset snap spring structure. A limiting sleeve 72 is fixed to one end of the forward pusher 71 facing the eccentric guide wheel 52, and the limiting sleeve 72 is sleeved on the outside of the eccentric guide wheel 52. A trapezoidal top platform 73 is provided on the inner wall of the limiting sleeve 72 and engages with the trapezoidal push platform 53. A sealing push ring 74 is fixed to the side wall of the forward pusher 71 facing the liquid storage ring 32, and the sealing push ring 74 can slide along the liquid storage ring 32. The sidewall of the liquid ring sleeve 32 enters into the liquid storage ring sleeve 32 and can squeeze the annular sponge block 33 inside it. The forward push tank 71 slides back and forth, pushing the coolant and lubricant. The limiting sleeve 72 is sleeved with the eccentric guide wheel 52 to limit the range of motion. The trapezoidal top platform 73 is pushed by the trapezoidal push platform 53, triggering displacement. The sealing push ring 74 squeezes the annular sponge block 33 to release the coolant. The conical liquid storage tank 75 stores the lubricant. These sub-components work together: the engagement of the trapezoidal top platform 73 drives the forward push tank 71 to move, the sealing push ring 74 pumps the coolant, and the conical liquid storage tank 75 outputs lubricant. The principle realizes self-driven fluid management. Please see the appendix Figure 9 - Appendix Figure 10 The forward push tank 71 is equipped with a conical liquid storage chamber 75, and the contact part between the conical liquid storage chamber 75 and the transmission main shaft 51 is equipped with a coating ball structure. The conical liquid storage chamber 75 is located inside the forward push tank 71, stores lubricant and applies it to the transmission main shaft 51 through the coating ball structure. When the lubrication drive mechanism 7 moves back and forth, the lubricant in the conical liquid storage chamber 75 is evenly distributed to the surface of the transmission main shaft 51 by the coating ball structure, reducing frictional heat. Its working principle is independent: storing and outputting lubricant to ensure smooth transmission. This process is synchronized with the displacement, without external intervention, and maintains the stability of the central transmission mechanism 5.

[0026] Based on the above technical solution, embodiments of the present invention also provide a working principle for a hollow eccentric pin water-cooled oil-free scroll air compressor, including the following: When the drive motor 2 starts, it generates rotational torque, which is directly transmitted to the transmission main shaft 51 of the central transmission mechanism 5, causing the transmission main shaft 51 to rotate continuously. The rotation of the transmission main shaft 51 drives the eccentric guide wheel 52 to rotate synchronously. The eccentric guide wheel 52 is connected to the deflecting disk 61 of the vortex air compressor mechanism 6, causing the deflecting disk 61 to perform eccentric oscillation. The eccentric oscillation of the deflecting disk 61 drives the moving vortex channel 62 to move in the inner cavity of the end ring 41 of the air compressor kit mechanism 4. The moving vortex channel 62 and the stationary vortex channel 63 fit together to form a vortex motion trajectory. During this vortex motion, air is drawn in from the air inlet structure of the end ring 41 and compressed under the continuous squeezing of the moving vortex channel 62 and the stationary vortex channel 63. The compressed air is discharged through the output air pipe 64 in the center of the stationary vortex channel 63, completing the vortex air compressor operation. During the rotation of the transmission main shaft 51, the trapezoidal pusher 53 of the central transmission mechanism 5 rotates synchronously with the rotation of the eccentric guide wheel 52. The rotational motion of the trapezoidal pusher 53 engages with the trapezoidal top platform 73 of the lubrication drive mechanism 7. The trapezoidal pusher 53 pushes the trapezoidal top platform 73, causing the forward pusher 71 of the lubrication drive mechanism 7 to move along the inner wall of the main tank 1. The displacement of the forward pusher 71 is transmitted to the eccentric guide wheel 52 through the limiting sleeve 72. When the protruding part of the trapezoidal pusher 53 disengages from the trapezoidal top platform 73, the reset snap ring structure causes the forward pusher 71 to return to the initial state. The continuous rotation of the trapezoidal pusher 53 repeatedly pushes and releases the trapezoidal top platform 73, causing the forward pusher 71 to form a reciprocating motion. The reciprocating motion of the forward push tank 71 acts on the liquid storage ring 32 of the transfer kit mechanism 3. The sealing push ring 74 of the lubrication drive mechanism 7 moves synchronously with the forward push tank 71. The sealing push ring 74 enters the liquid storage ring 32 and squeezes the annular sponge block 33. When the annular sponge block 33 is squeezed, it releases the stored coolant. The coolant flows out through the transfer channel 34 of the transfer kit mechanism 3. The output end of the transfer channel 34 extends to the input channel of the end ring 41 of the air compressor kit mechanism 4. The coolant flows into the input channel of the end ring 41 from there. The coolant flows in the input channel and enters... The inner side of the expanded diameter annular groove 42 is connected to the input end of the cooling liquid reservoir 43 through the output channel, and the coolant enters the cooling liquid reservoir 43 through this channel. In the cooling liquid reservoir 43, the coolant flows through the heat-conducting rings distributed on the outer wall, and the heat is dissipated to the external environment through the heat-conducting rings, causing the coolant temperature to drop. The cooled coolant flows out from the output end of the outer ring side wall of the cooling liquid reservoir 43 through the return pipe 44. The output end of the return pipe 44 is connected to the output end of the return channel 35 of the transfer kit mechanism 3, and the coolant returns to the reservoir ring 32 through the return channel 35, forming a closed loop circulation of the coolant. During the coolant circulation process, the coolant flows through the surfaces of the moving vortex channel 62 and the stationary vortex channel 63 of the vortex air compressor mechanism 6. When the coolant enters the input channel of the end ring sleeve 41 from the transfer channel 34, it contacts the outer surfaces of the moving disk 61 and the moving vortex channel 62. When it flows in the expansion annular groove 42 and the coolant reservoir 43, the coolant surrounds the heat exchange zone of the stationary vortex channel 63. The continuous flow of the coolant carries away the heat generated by the moving vortex channel 62 and the stationary vortex channel 63. The cooling process of the coolant occurs at the heat conduction ring of the coolant reservoir 43, and then flows back to the reservoir ring sleeve 32 for re-storage. Meanwhile, during the reciprocating motion of the forward push tank 71 of the lubrication drive mechanism 7, the lubricant inside the conical liquid storage tank 75 is applied to the surface of the transmission main shaft 51 through the coating ball structure. The coating ball structure contacts the transmission main shaft 51 as the forward push tank 71 moves, and evenly coats the lubricant inside the conical liquid storage tank 75 onto the transmission main shaft 51. The coating process of the lubricant occurs synchronously with the reciprocating motion of the forward push tank 71, ensuring that the rotating surface of the transmission main shaft 51 is continuously lubricated. With the drive motor 2 running continuously, the above process forms a continuous cycle: the rotation of the transmission spindle 51 drives the vortex air compressor mechanism 6 to perform air compression; at the same time, the rotation of the trapezoidal pusher 53 triggers the reciprocating movement of the lubrication drive mechanism 7; the reciprocating movement of the lubrication drive mechanism 7 pushes the annular sponge block 33 of the transfer kit mechanism 3 to release coolant; the coolant flows into the air compressor kit mechanism 4, and returns to the transfer kit mechanism 3 after being cooled; the coolant contacts and cools the vortex air compressor mechanism 6 in the flow; the reciprocating movement of the lubrication drive mechanism 7 applies lubricant to the transmission spindle 51; The rotational torque of the drive motor 2 maintains the rotational speed of the transmission spindle 51, ensuring that the vortex motion of the moving vortex channel 62 and the stationary vortex channel 63 of the vortex air compressor mechanism 6 is uninterrupted. Each rotation cycle of the trapezoidal pusher 53 corresponds to one displacement cycle of the forward pusher tank 71 of the lubrication drive mechanism 7. In each displacement, the amount of the sealing pusher ring 74 that squeezes the annular sponge block 33 depends on the displacement amplitude. The amount of coolant released is determined by the degree of compression of the annular sponge block 33. In the flow path, the coolant enters the input channel, the expansion annular groove 42, the cooling liquid storage plate 43, the return pipe 44 and the return channel 35 from the liquid storage ring 32 through the transfer channel 34, and finally returns to the liquid storage ring 32. The cooling efficiency of the coolant depends on the heat exchange efficiency of the heat-conducting ring of the cooling liquid storage plate 43. The lubricant application process relies on the storage of the conical liquid storage tank 75 and the mechanical action of the application ball structure. The compression operation of the vortex air compressor 6 is synchronized with the flow of coolant. When the coolant comes into contact with the moving vortex channel 62, it occurs at the swing position of the deflecting moving disk 61. When it comes into contact with the stationary vortex channel 63, it occurs in the inner cavity of the end ring sleeve 41. The return channel 35 guides the cooled coolant back to the storage ring sleeve 32. The annular sponge block 33 reabsorbs the coolant to prepare for the next compression. The reset snap ring structure ensures that after the forward push tank 71 retracts, the sealing push ring 74 leaves the storage ring sleeve 32, allowing the annular sponge block 33 to return to its original shape to store coolant. The entire working cycle is uninterrupted: the input of drive motor 2 is continuously converted into vortex air compressor operation and cooling lubrication drive; the reciprocating frequency of lubrication drive mechanism 7 is determined by the rotational speed of transmission spindle 51 and synchronized with the rotation of eccentric guide wheel 52; the initiation and maintenance of coolant circulation depend on the action of lubrication drive mechanism 7; the flow direction of coolant is fixed by the paths of transfer channel 34 and return channel 35; lubricant consumption is regulated by the capacity of conical reservoir 75; the application process is uninterrupted. The working cycle continues until the drive motor 2 stops. When it stops, the speed of the transmission spindle 51 decreases, the pushing frequency of the trapezoidal pusher 53 decreases, the displacement amplitude of the lubrication drive mechanism 7 decreases, the amount of coolant released decreases, and the lubrication application rate decreases. All components return to their initial state after the movement stops, but the coolant and lubricant are stored in the annular sponge block 33 and the conical reservoir 75 for the next start-up. The power output of the drive motor 2 matches the load of the mechanism: at high speed, the transmission spindle 51 rotates faster, the vortex compression frequency increases, the trapezoidal pusher 53 moves faster, the reciprocating frequency of the lubrication drive mechanism 7 increases, the coolant flow rate increases, the lubrication application rate increases, the closed-loop design of the coolant circulation ensures continuous heat dissipation, and the lubrication application prevents transmission jamming. The workflow always starts with the start of the drive motor 2 and ends with the stop of the drive. During the process, the mechanical interaction of each component generates a chain reaction: rotation triggers a vortex, the vortex triggers reciprocating motion, the reciprocating motion triggers fluid flow, the fluid flow achieves thermal management, the thermal management supports continuous rotation, and the cooling of the coolant occurs at a specific stage in the cooling reservoir 43, but the cooling effect covers the entire vortex area.
