Description

Technical Field

[0001] This invention relates to the field of air compressor technology, specifically to an air compressor with vibration reduction and noise reduction functions. Background Technology

[0002] An oil-free air compressor is a mechanical device that compresses gas without the need for lubricating oil. It uses a motor-driven crankshaft connecting rod mechanism to cause a piston to reciprocate within a cylinder, thus achieving gas intake, compression, and discharge. Compared to traditional oil-lubricated air compressors, oil-free air compressors discharge compressed gas without oil, meeting the needs of industries with high requirements for air source cleanliness, such as medical, food, electronics, and spray painting, and have broad application prospects.

[0003] However, existing oil-free air compressors still have many shortcomings in practical use. First, the crankcase and motor housing of most oil-free air compressors are separate structures, which not only increases the number of parts and assembly steps, but also leads to increased vibration and higher failure rate due to assembly errors. In addition, the vibration damping structure of existing oil-free air compressors mostly adopts passive methods such as vibration damping pads, which have unsatisfactory vibration damping effect. Resonance can easily occur between the motor and the vibration damping pads, which can actually aggravate vibration and noise. Sound insulation measures usually rely on external sound insulation covers or sound insulation cotton, which are bulky, inconvenient to disassemble and assemble, and not conducive to daily maintenance and pipeline operation. The above problems result in existing oil-free air compressors having defects such as high noise, strong vibration, bulky size, and difficult maintenance, making it difficult to meet the comprehensive requirements of modern industry for lightweight, low noise, and high reliability equipment. Summary of the Invention

[0004] The purpose of this invention is to design a simplified and lightweight oil-free air compressor and to specifically design a vibration-damping and noise-reducing structure. To achieve the above objective, this invention adopts the following technical solution: An air compressor with vibration-damping and noise-reducing functions includes an oil-free air compressor body, an air guide shroud installed on the air guide shroud, an organic cover I installed on the air guide shroud, an organic cover II installed on the oil-free air compressor body, and a vibration-damping and noise-reducing component provided on the oil-free air compressor body. The vibration-damping and noise-reducing component includes two symmetrically arranged frames on both sides of the oil-free air compressor body, each frame containing a sound-insulating airbag I, and a suction cup at each end of the two frames. The sound-insulating airbag I can be inflated within the frame to form a sound barrier on the outside of the oil-free air compressor body. The suction cup flips as the sound-insulating airbag I expands, and the suction cup is used to provide limiting and vibration reduction for the oil-free air compressor body. Two rotating plates are symmetrically arranged on the air guide cover. A carrier rod is fixedly connected to the far end of the two rotating plates. A sound-insulating rubber strip is fixedly connected between the two carrier rods. The sound-insulating rubber strip is located on the top of the oil-free air compressor body. Two sound-insulating airbags are symmetrically fixedly connected to the sound-insulating rubber strip. The sound-insulating rubber strip, together with the two expanded sound-insulating airbags and the two expanded sound-insulating airbags, form a hollow box with a bottom opening fitted onto the oil-free air compressor body. Two sealing frames are installed on each of the two carrier rods. Each sealing frame has a sealing plate that is slidably connected inside. The sealing frames are used to block the side of the air guide shroud and machine cover that interacts with the outside world.

[0005] Furthermore, the vibration damping and noise reduction assembly also includes a support frame, which is fixedly connected to the bottom of the oil-free air compressor body. An air groove is opened inside the support frame, and an air pump is installed on the support frame, connected to the air groove. Two housing frames are fixedly connected to both ends of the support frame, and each end of the two housing frames is rotatably connected to a connecting rod. Each connecting rod is fixedly connected to a torsion spring, with the end of the torsion spring away from the connecting rod fixedly connected to the housing frame. Each connecting rod is fixedly connected to a support rod at the end away from the corresponding torsion spring, with the end of the support rod away from the connecting rod fixedly connected to a sound-insulating airbag. Multiple pull ropes are fixedly connected to both ends of the inner walls of the two sound-insulating airbags. Each connecting rod is fixedly connected to a support plate, and each support plate is slidably connected to a slide rod. Each slide rod is fixedly connected to a suction cup, and each slide rod is fitted with a tension spring, with both ends of the tension spring fixedly connected to the suction cup and the support plate, respectively.

[0006] Furthermore, two bearing blocks are symmetrically fixedly connected to the outer wall of the air guide hood. Each bearing block is rotatably connected to a rotating plate. Two torsion springs are symmetrically fixedly connected to each of the two rotating plates. The end of the torsion spring away from the rotating plate is fixedly connected to the bearing block. Two limiting plates are symmetrically fixedly connected to the outer wall of the air guide hood. A bearing ring is fixedly connected to the air guide hood. A sound-insulating airbag is fixedly connected to the bearing ring on the side near the bearing ring. The two sound-insulating airbags are fixedly connected to two carrier rods respectively. Multiple pull ropes are fixedly connected to both ends of the inner wall of each of the two sound-insulating airbags. Two L-shaped rods are symmetrically fixedly connected to each of the two carrier rods. The ends of the two L-shaped rods on the same carrier rod away from the carrier rod are fixedly connected to a sealing frame. The ends of the two carrier rods near the bearing ring are fixedly connected to a sealing frame. Multiple pull ropes are provided in each sealing frame. The two ends of the pull ropes are fixedly connected to the sealing frame and the sealing plate respectively. Two air guide pipes are symmetrically fixedly connected to the support frame. The air guide pipes are connected to the air duct. The ends of the two air guide pipes away from the support frame are respectively inserted and connected to a sound-insulating airbag.

[0007] Furthermore, a magnet is provided on the side of the support rod away from the connecting rod and close to the oil-free air compressor body, and a magnet is provided on each end of the side of the carrier rod away from the rotating plate. The magnets on the opposite sides of the support rod and the carrier rod have opposite magnetic properties.

[0008] Furthermore, a magnet is provided on the side of the sealing frame away from the pull rope three. The four sealing frames are arranged in pairs, with the two sealing frames fixed to the L-shaped rod forming one group and the two sealing frames fixed to the carrier rod forming another group. The magnets on the sealing plates of the two sealing frames in the same group have opposite magnetic properties on their opposite sides.

[0009] Furthermore, the surfaces of soundproof airbag one, soundproof rubber strip, and soundproof airbag two are all covered with soundproof fabric to block sound penetration.

[0010] Furthermore, the limiting plate is located at the bottom of the bearing block. The limiting plate is used to limit the rotation angle of the rotating plate, and the two support rods on the same frame are staggered.

[0011] Furthermore, both soundproof airbags are connected to the air groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are: Through the design of the shock-absorbing and noise-reducing components, relying on the air-path linkage drive structure, after inflation, they can be combined to form a sealed hollow sound barrier with a bottom opening, blocking the transmission of operating noise to the outside; combined with suction cups to fix the working surface, and with tension springs to form an elastic buffer and shock-absorbing structure, it can offset the vibration of the equipment during operation, prevent the equipment from slipping and shifting, and take into account sound insulation and noise reduction, as well as shock absorption and stability.

[0013] Through the design of shock-absorbing and noise-reducing components, the equipment will be linked to reset after shutdown and pressure relief. In conjunction with the magnetic linkage structure, the sealing plate will be automatically driven to close and block the external interaction port of the equipment. In the idle state, it will isolate the external dust and debris from entering the machine body, prevent the internal piston, crankshaft and other moving components from being worn by impurities, and reduce the frequency of equipment maintenance.

[0014] Through the design of the vibration damping and noise reduction components, a split-combination design is adopted. Relying on magnetic alignment and plug-in air circuit for fixation, the structure can be separated synchronously with the body parts when the equipment is disassembled for maintenance, without the need to disassemble the sound insulation and vibration damping components separately. When the equipment is reset and reassembled, only the air circuit needs to be plugged in to complete the positioning and assembly, which greatly reduces the workload of maintenance and disassembly. At the same time, the structure can automatically retract when idle, without occupying the surrounding space, which is convenient for personnel to operate and debug daily.

[0015] The oil-free air compressor body adopts a crankcase and motor die-cast integrated structure, reducing the number of separate connecting parts, reducing the assembly process, and eliminating the hidden dangers of loosening, abnormal noise, and transmission misalignment caused by the gaps in the separate assembly. This reduces the failure rate of the whole machine from the structural source. Combined with the single cylinder integrated design, it reduces the amount of consumables, significantly reduces the weight of the whole machine, reduces the size of the whole machine, improves the adaptability of the equipment to the site and installation compatibility, and is suitable for small air source operations in multiple scenarios.

[0016] The extended integrated air guide shroud directly serves as the outer enclosure structure of the cylinder, fully covering the crankcase, cylinder and other high-temperature operating components of the whole machine. It can concentrate the airflow to complete the whole-area heat dissipation, which is different from the traditional local airflow heat dissipation structure. It improves the heat dissipation uniformity of high-temperature components, avoids the deformation, lubrication failure and aging damage of components due to long-term high-temperature operation, and extends the service life of the equipment.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] Reference Figures 1 to 14 As shown, an air compressor with shock absorption and noise reduction function includes an oil-free air compressor body 11, an air guide shroud 12 installed on the oil-free air compressor body 11, an organic cover 13 installed on the air guide shroud 12, and an organic cover 14 installed on the oil-free air compressor body 11. It should be added that the oil-free air compressor body 11 integrates the crankcase and motor, and is integrally formed by die casting process. The purpose is to reduce the number of parts and assembly steps, thereby further reducing the failure rate.

[0021] Furthermore, the air guide shroud 12 is designed as an extension, serving as the outer wall of the cylinder component of the oil-free air compressor body 11. This encloses the crankcase, cylinder, and other high-temperature components, allowing for concentrated airflow to achieve full-area heat dissipation and effectively cooling the crankcase, cylinder, and other high-temperature components.

[0022] Furthermore, the oil-free air compressor body 11 adopts a single-cylinder design, which can significantly reduce the number of parts, reduce the overall weight and dimensions, and provide overall machine compatibility.

[0023] The oil-free air compressor body 11 is equipped with a vibration damping and noise reduction component. The vibration damping and noise reduction component includes two symmetrically arranged frames 24 on both sides of the oil-free air compressor body 11. Each of the two frames 24 is equipped with a sound insulation airbag 28. Each end of the two frames 24 is equipped with a suction cup 212. The sound insulation airbag 28 can be inflated and expanded inside the frame 24, thereby forming a sound insulation barrier on the outside of the oil-free air compressor body 11. The suction cup 212 flips as the sound insulation airbag 28 expands. The suction cup 212 is used to provide limit and vibration reduction for the oil-free air compressor body 11. Two rotating plates 215 are symmetrically arranged on the air guide shroud 12. Each of the two rotating plates 215 is fixedly connected to a carrier rod 218 at one end that is far apart from each other. A sound-insulating rubber strip 219 is fixedly connected between the two carrier rods 218. The sound-insulating rubber strip 219 is located on the top of the oil-free air compressor body 11. Two sound-insulating air bags 221 are symmetrically fixedly connected to the sound-insulating rubber strip 219. The sound-insulating rubber strip 219, together with the two expanded sound-insulating air bags 28 and the two sound-insulating air bags 221, form a hollow box with a bottom opening fitted on the oil-free air compressor body 11. Two sealing frames 224 are provided on each of the two carrier rods 218. Each sealing frame 224 has a sealing plate 225 slidably connected inside it. The sealing frames 224 are used to block the side of the air guide shroud 12 and the machine cover 13 that interacts with the outside world.

[0024] The vibration damping and noise reduction assembly also includes a support frame 21, which is fixedly connected to the bottom of the oil-free air compressor body 11. An air groove 22 is provided inside the support frame 21, and an air pump 23 is installed on the support frame 21. The air pump 23 is connected to the air groove 22. Two housing frames 24 are fixedly connected to both ends of the support frame 21, and a connecting rod 25 is rotatably connected to each end of the two housing frames 24. A torsion spring 26 is fixedly connected to each connecting rod 25. The end of the torsion spring 26 away from the connecting rod 25 is fixedly connected to the housing frame 24. A support rod 27 is fixedly connected to the end of each connecting rod 25 away from the corresponding torsion spring 26. The end of the support rod 27 away from the connecting rod 25 is fixedly connected to the sound insulation airbag 28. Multiple pull ropes 29 are fixedly connected to both ends of the inner wall of the two sound insulation airbags 28.

[0025] Each link 25 is fixedly connected to a support plate 210, each support plate 210 is slidably connected to a slide rod 211, each slide rod 211 is fixedly connected to a suction cup 212, and each slide rod 211 is fitted with a tension spring 213, the two ends of the tension spring 213 are fixedly connected to the suction cup 212 and the support plate 210 respectively.

[0026] Two bearing blocks 214 are symmetrically fixedly connected to the outer wall of the air guide shroud 12. The two bearing blocks 214 are rotatably connected to a rotating plate 215. Two torsion springs 216 are symmetrically fixedly connected to each of the two rotating plates 215. The end of the torsion spring 216 away from the rotating plate 215 is fixedly connected to the bearing block 214. Two limiting plates 217 are symmetrically fixedly connected to the outer wall of the air guide shroud 12. A bearing ring 220 is fixedly connected to the air guide shroud 12. A sound insulation airbag 221 on the side close to the bearing ring 220 is fixedly connected to the bearing ring 220. The two sound insulation airbags 221 are fixedly connected to two carrier rods 218. Multiple pull ropes 222 are fixedly connected to both ends of the inner wall of the two sound insulation airbags 221.

[0027] Two L-shaped rods 223 are symmetrically fixedly connected to each of the two carrier rods 218. The ends of the two L-shaped rods 223 on the same carrier rod 218 away from the carrier rod 218 are fixedly connected to a sealing frame 224. The ends of the two carrier rods 218 near the bearing ring 220 are fixedly connected to a sealing frame 224. Each sealing frame 224 is provided with multiple pull ropes 226. The two ends of the pull ropes 226 are fixedly connected to the sealing frame 224 and the sealing plate 225 respectively. Two air guide pipes 227 are symmetrically fixedly connected to the support frame 21. The air guide pipes 227 are connected to the air duct 22. The ends of the two air guide pipes 227 away from the support frame 21 are respectively inserted and connected to a sound insulation airbag 221.

[0028] Among them, the soundproof airbag 28 is provided with a through groove, which is used for the external pipeline of the oil-free air compressor body 11.

[0029] Among them, a magnet is provided on the side of the support rod 27 away from the connecting rod 25 and close to the oil-free air compressor body 11, and a magnet is provided at each end of the side of the carrier rod 218 away from the rotating plate 215. The magnets on the opposite sides of the support rod 27 and the carrier rod 218 have opposite magnetic properties. The function is to make the support rod 27 and the carrier rod 218 magnetically attracted and fixed, so as to ensure the stability of the soundproof box composed of the soundproof airbag 28, the soundproof rubber strip 219, and the soundproof airbag 221.

[0030] The purpose of pull rope 1 29, pull rope 222, and pull rope 3 226 is to use elasticity to cause the structure to reset. Specifically, pull rope 1 29 assists the sound insulation airbag 1 28 to exhaust and contract, so that the sound insulation airbag 1 28 is completely stored in the storage frame 24; pull rope 222 assists the sound insulation airbag 2 221 to exhaust and contract, so that the sound insulation airbag 2 221 and the sound insulation rubber belt 219 contract towards the center of the oil-free air compressor body 11; pull rope 3 226 assists the sealing plate 225 to move, so that the sealing plate 225 is stored in the sealing frame 224.

[0031] Among them, a magnet is provided on the side of the sealing frame 224 away from the pull rope 226. The four sealing frames 224 are in pairs. The two sealing frames 224 fixed to the L-shaped rod 223 form one group, and the two sealing frames 224 fixed to the carrier rod 218 form another group. The magnets on the sealing plates 225 of the two sealing frames 224 in the same group have opposite magnetic properties. The function is to make the two sealing plates 225 in the same group close together, and the two sealing plates 225 are pulled closer to each other by magnetic attraction, so that the sealing plates 225 slide from the sealing frame 224 and the pull rope 226 undergoes elastic deformation.

[0032] Among them, the surfaces of soundproof airbag 28, soundproof rubber strip 219, and soundproof airbag 221 are all covered with soundproof fabric to block sound penetration. Thus, while ensuring the elasticity of soundproof airbag 28, soundproof rubber strip 219, and soundproof airbag 221, the housing composed of soundproof airbag 28, soundproof rubber strip 219, and soundproof airbag 221 can achieve silent treatment of the oil-free air compressor body 11.

[0033] It should be noted that when the soundproofing airbag 221 is fully inflated, the bottom of the soundproofing airbag 221 is flush with the bottom surface of the frame 24. Its function is to ensure that the bottom of the soundproofing box is sealed and to prevent sound leakage.

[0034] Among them, the sound-insulating rubber strip 219 is fixedly connected to both rotating plates 215.

[0035] Wherein: the limiting plate 217 is located at the bottom of the bearing block 214, and the limiting plate 217 is used to limit the rotation angle of the rotating plate 215.

[0036] Among them, the two support rods 27 on the same frame 24 are staggered, so that when the sound insulation airbag 28 is fully retracted and placed in the frame 24, both support rods 27 in the same frame 24 can be put into the frame 24.

[0037] Among them, both soundproof airbags 28 are connected to the air groove 22.

[0038] It should be noted that: the support rod 218, the second sound-insulating airbag 221, the sealing frame 224, and the air guide shroud 12 are connected. The housing frame 24 and the first sound-insulating airbag 28 are connected to the oil-free air compressor body 11. That is, the sound-insulating rubber belt 219, the second sound-insulating airbag 221, and the first sound-insulating airbag 28 can be disassembled separately. When it is necessary to perform work that requires disassembly, such as maintenance or adjustment, on the oil-free air compressor body 11 and the air guide shroud 12, the sound-insulating rubber belt 219, the second sound-insulating airbag 221, and the first sound-insulating airbag 28 will separate simultaneously with the separation of the oil-free air compressor body 11 and the air guide shroud 12. When resetting is required, only the air guide shroud 12 needs to be reinstalled, and the air guide pipe 227 needs to be connected to the sound-insulating airbag 221.

[0039] In the initial state, i.e. before the oil-free air compressor is running, the internal structures of the vibration damping and noise reduction components are as follows: The air guide shroud 12 is installed on the oil-free air compressor body 11. Cover 13 is closed onto the air guide shroud 12, and cover 14 is closed onto the oil-free air compressor body 11. Two air guide pipes 227 are respectively connected to the corresponding soundproof airbags 221. The air pump 23 has not yet started operating. Gas is discharged from the soundproof airbag 28. At this time, the soundproof airbag 28 is fully contracted under the pull of the pull rope 29, and the entire soundproof airbag 28 is retracted into the housing frame 24. The torsion spring 26 has not yet undergone elastic deformation. The two support rods 27 on the same housing frame 24 are folded downwards and retracted into the housing frame 24. The open end of each suction cup 212 is flipped to a horizontal position, and the tension spring 213 has not yet undergone elastic deformation. During the elastic deformation process, before the torsion spring 216 undergoes elastic deformation, the rotating plate 215 flips to a vertical position, and the carrier rod 218 abuts against the outer wall of the air guide shroud 12. At this time, the two ends of the sound-insulating rubber strip 219 connected to the carrier rod 218 are driven upward and rolled up, and the gas in the two sound-insulating airbags 221 is discharged. The sound-insulating airbags 221 are fully contracted under the pull of the pull rope 222. At this time, a set of sealing frames 224 connected to the L-shaped rod 223 flips to fit against the top surface of the cover 13. The set of sealing frames 224 fixed to the carrier rod 218 covers the end of the air guide shroud 12 near the bearing ring 220, and the two sealing plates 225 of the same set are magnetically attracted and fixed to each other. The sealing plates 225 slide out from inside the sealing frames 224, and the pull rope 226 undergoes elastic deformation. At this time, the end of the cover 13 and the air guide shroud 12 that interacts with the outside world is blocked by the sealing frames 224 and sealing plates 225.

[0040] When the oil-free air compressor is running, the compressor body 11 is placed on the working surface, and the vibration damping and noise reduction components operate as follows: The user drives the air pump 23 to operate, causing the air pump 23 to fill the air tank 22 with airflow. The gas flows from the air tank 22 into the soundproof airbags 28 at both ends, and the gas also flows from the air tank 22 into the two soundproof airbags 221 via the two air ducts 227. The gas flowing into the soundproof airbags 28 gradually fills them, causing the soundproof airbags 28 to inflate. At this time, the soundproof airbags 28 push the two support rods 27 upward to rotate in opposite directions, causing the torsion spring 26 to undergo elastic deformation. While the soundproof airbags 28 are inflating, the pull rope 29 is pulled accordingly, causing elastic deformation.

[0041] As the soundproof airbag 28 inflates, the two support rods 27 are pushed by the airbag 28 to gradually rotate into a vertical position. With the rotation of the support rods 27, the support plate 210 rotates synchronously with the connecting rod 25, causing the support plate 210 to drive the suction cup 212 to gradually flip downwards. At this time, the open end of the suction cup 212 gradually flips towards and contacts the working surface where the oil-free air compressor is placed. As the soundproof airbag 28 continues to inflate, the suction cup 212 contacts and presses against the mounting surface. Meanwhile, the slide rod 211... The support plate 210 slides downwards, causing the tension spring 213 to undergo elastic deformation, which gradually expels the air from the suction cup 212. At this time, the suction cup 212 is attracted and fixed to the mounting surface, that is, the oil-free air compressor body 11 and the mounting surface are attracted and fixed by the suction cup 212. Since the suction cup 212 and the oil-free air compressor body 11 are connected by the tension spring 213, the tension spring 213 forms an elastic buffer between the oil-free air compressor body 11 and the mounting surface, providing elastic shock absorption for the operation of the oil-free air compressor.

[0042] While the first soundproofing airbag 28 inflates, gas also fills the second soundproofing airbag 221, causing it to inflate as well. The second soundproofing airbag 221 expands towards the first soundproofing airbag 28 on both sides. Simultaneously, the second soundproofing airbag 221 pulls the second pull rope 222, causing it to elastically deform. During this expansion, the second soundproofing airbag 221 also pulls the soundproofing rubber strip 219, causing it to connect with the support rod 218. Both ends of the sound insulation rubber strip 219 gradually extend downward from the previously upward rolled-up shape, causing the rotating plate 215 to rotate downward. This causes the rotating plate 215 to flip downward on the bearing block 214. At this time, the second torsion spring 216 undergoes elastic deformation. When the rotating plate 215 rotates to contact the limiting plate 217, the rotation of the rotating plate 215 is restricted, and the rotating plate 215 cannot continue to rotate downward. At this time, the carrier rod 218 rotates with the rotating plate 215 and becomes horizontal. The sound insulation rubber strip 219 unfolds and flattens, and the second sound insulation airbag 221 fully inflates.

[0043] It should be noted that when the second soundproof airbag 221 and the first soundproof airbag 28 are fully inflated, the support rod 27 rotates to a vertical position, and the carrier rod 218 flips to a horizontal position. The support rod 27 and the carrier rod 218 are attracted to each other by magnets.

[0044] During the flipping process of the carrier rod 218, the carrier rod 218 drives the sealing frame 224 to move through the L-shaped rod 223, so that multiple sealing frames 224 move to both sides of the oil-free air compressor body 11. The side of the air guide shroud 12 and the machine cover 13 that interacts with the outside world is no longer blocked, thereby releasing the magnetic attraction between the sealing plates 225. At this time, under the elastic reset pull of the pull rope 3 226, the sealing plate 225 is pulled into the sealing frame 224.

[0045] It should be noted that when the first soundproof airbag 28 and the second soundproof airbag 221 are fully inflated and the soundproof rubber strip 219 is laid flat, a soundproof enclosure is formed covering the oil-free air compressor. The enclosure and the oil-free air compressor are attached to the mounting surface by suction cups 212, and elastic shock absorption is provided by tension springs 213. The bottom of the enclosure fits tightly against the mounting surface, thus avoiding any gaps at the bottom that could cause sound leakage.

[0046] At this time, the user can perform operations such as connecting pipelines to the oil-free air compressor body 11 through the through groove on the soundproof airbag 28.

[0047] After using the oil-free air compressor, the user needs to reset the vibration damping and noise reduction components, as follows: The user operates the air pump 23, which draws out the gas from the first soundproof airbag 28 and the second soundproof airbag 221. At this time, the gas in the first soundproof airbag 28 is drawn out and gradually contracts. Under the elastic reset pull of the pull rope 29, the first soundproof airbag 28 contracts and enters the housing frame 24. Then the first soundproof airbag 28 no longer pushes the support rod 27. Under the elastic reset action of the torsion spring 26, the support rod 27 flips and enters the housing frame 24. At this time, the user releases the suction cup 212 from the adsorption state of the mounting surface. At the same time as the support rod 27 flips, the connecting rod 25 drives the suction cup 212 to flip, so that the open end of the suction cup 212 is horizontal. At the same time, under the elastic reset action of the tension spring 213, the suction cup 212 slides and resets on the support plate 210.

[0048] As the gas inside the second soundproof airbag 221 is extracted, it gradually contracts. Under the elastic return pull of the second pull rope 222, the two ends of the second soundproof airbag 221 contract inward. At this time, under the elastic return action of the second torsion spring 216, the rotating plate 215 rotates upward, causing the two ends of the soundproof rubber strip 219 to roll upward. The upward rotation of the rotating plate 215 drives the carrier rod 218 to flip upward until it contacts the air guide cover 12. At this time, the carrier rod 218 drives the sealing frame 224 to move synchronously, causing the sealing frame 224, which is fixed to the L-shaped rod 223, to flip to the top of the first cover 13, corresponding to the bearing ring 220. The two sealing frames 224 are brought closer together. At this time, both sealing frames 224 in the two sets are close to each other, and the magnets of the sealing plates 225 attract each other, causing the two sealing plates 225 in the two sets to be pulled closer and magnetically attracted. At the same time, the sealing plates 225 slide inside the sealing frames 224, causing the pull rope 3 226 to undergo elastic deformation. At this time, the sealing frames 224 and sealing plates 225 form a shielding cover on the end of the air guide shroud 12 and the machine cover 13 that interacts with the outside, thereby sealing the end of the air guide shroud 12 and the machine cover 13 that interacts with the outside, preventing external impurities from entering the interior when the oil-free air compressor is idle. At this time, the vibration damping and noise reduction components are reset.

[0049] It should be noted that after the shock absorption and noise reduction components are reset, the body of the oil-free air compressor is exposed, which makes it easier for the user to operate the oil-free air compressor.

[0050] In summary, the following beneficial effects can be achieved through the design of vibration damping and noise reduction components: Through the design of the shock-absorbing and noise-reducing components, relying on the air-path linkage drive structure, after inflation, they can be combined to form a sealed hollow sound barrier with a bottom opening, blocking the transmission of operating noise to the outside; combined with suction cup 212 to adsorb and fix the working surface, and with tension spring 213 to form an elastic buffer and shock-absorbing structure, to offset the vibration of the equipment operation, prevent the equipment from slipping and shifting, and take into account sound insulation and noise reduction, shock absorption and stability.

[0051] Through the design of shock-absorbing and noise-reducing components, the equipment will be linked to reset after shutdown and pressure relief. In conjunction with the magnetic linkage structure, the sealing plate 225 will be automatically driven to close and block the external interaction port of the equipment. In the idle state, it will isolate the external dust and debris from entering the machine body, prevent the internal piston, crankshaft and other moving components from being worn by impurities, and reduce the frequency of equipment maintenance.

[0052] Through the design of the vibration damping and noise reduction components, a split-combination design is adopted. Relying on magnetic alignment and plug-in air circuit for fixation, the structure can be separated synchronously with the body parts when the equipment is disassembled for maintenance, without the need to disassemble the sound insulation and vibration damping components separately. When the equipment is reset and reassembled, only the air circuit needs to be plugged in to complete the positioning and assembly, which greatly reduces the workload of maintenance and disassembly. At the same time, the structure can automatically retract when idle, without occupying the surrounding space, which is convenient for personnel to operate and debug daily.

[0053] The oil-free air compressor body 11 adopts a crankcase and motor die-cast integrated structure, reducing the number of separate connecting parts, reducing the assembly process of the whole machine, and eliminating the hidden dangers of loosening, abnormal noise, and transmission misalignment caused by the gaps in the separate assembly, thereby reducing the failure rate of the whole machine from the structural source. Combined with the single cylinder integrated design, the amount of consumables is reduced, the weight of the whole machine is significantly reduced, the size of the whole machine is reduced, and the adaptability of the equipment to the site and the compatibility of installation are improved, making it suitable for small air source operations in multiple scenarios.

[0054] The extended integrated air guide shroud 12 directly serves as the outer enclosure structure of the cylinder, fully covering the crankcase, cylinder and other high-temperature operating components of the whole machine. It can concentrate the airflow to complete the whole-area heat dissipation, which is different from the traditional local airflow heat dissipation structure. It improves the heat dissipation uniformity of high-temperature components, avoids the deformation, lubrication failure and aging damage of components due to long-term high-temperature operation, and extends the service life of the equipment.
