Description

Technical Field

[0001] The present invention relates to an air compressor, and in particular to an oil-free air compressor with an air intake and heat dissipation structure applied in the field of air compressors. Background Art

[0002] Air compressor is also called air compressor for short. It is a device used to compress gas. The structure of air compressor is similar to that of water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. Air compressor is the main body of air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy.

[0003] During the continuous operation of the air compressor, the internal temperature of the air compressor cylinder will rise. If this continues for a long time, it will cause the air compressor to shut down due to high temperature or even be damaged, affecting people's production and use.

[0004] After searching, the Chinese invention patent with publication number CN106468254B ​​discloses a main engine structure of a piston intake and heat dissipation type oil-free air compressor, including a crankcase, a compression cylinder and a crankshaft. The compression cylinder includes a cylinder body connected to the crankcase at one end, a cylinder head with an exhaust hole on the other end of the cylinder body, and a piston located in the cylinder body. A compression chamber is formed between the piston and the exhaust assembly, an exhaust assembly is provided between the piston and the cylinder head, the piston is connected to the crankshaft through a connecting rod, a heat dissipation channel connected to the crankcase is provided on the outer sleeve of the compression cylinder, the piston is provided with an intake channel connecting the crankcase and the compression chamber, the intake channel is provided with a one-way valve opened toward the compression chamber, the crankcase is provided with an air inlet, and the crankshaft is provided with an intake fan driving the air flow through the air inlet into the crankcase.

[0005] Based on the above search, combined with the existing technology, it is found that the cooling effect of the cylinder block and the cylinder head is poor, and the temperature inside the cylinder block is still too high. At the same time, in the process of cooling the cylinder block and the cylinder head, dust and the like will enter the cylinder, which can easily reduce the service life of the entire air compressor. Therefore, an oil-free air compressor with an air intake heat dissipation structure is proposed to improve the above problems. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing structure has a poor cooling effect on the cylinder body and the cylinder head, and the temperature inside the cylinder body is still too high. At the same time, in the process of cooling the cylinder body and the cylinder head, dust and the like will enter the cylinder, which can easily cause the service life of the entire air compressor to be reduced.

[0007] In order to solve the above problems, the present invention provides an oil-free air compressor with an air intake and heat dissipation structure, comprising:

[0008] A bottom plate, a top outer wall of the bottom plate is fixedly connected to a support frame, and a top of the support frame is fixedly connected to a motor;

[0016] As a further supplement to the present application, negative pressure suction will be generated at the intake pipe when the air compressor is started. At this time, negative pressure suction will also be generated in the cooling pipe connected to the intake pipe, and an intake plate is connected to one end of the cooling pipe. The intake groove opened on one side of the intake plate can accelerate the flow rate of air around the cylinder body. At the same time, the intake groove is in an inclined elliptical shape, which expands the intake area of ​​the intake plate and avoids dead corners when cooling the cylinder body, meeting people's air intake and heat dissipation needs. When the intake plate accelerates the flow rate of gas around the cylinder body, the negative pressure suction near the intake hole is greater. Therefore, the intake plate is set to be thick at both ends and narrow in the middle. The air flow on both sides of the intake plate can be increased, so that the air flow rate in each area can be relatively balanced, thereby achieving uniform cooling around the cylinder body.

[0017] As another improvement of the present application, the outer walls on the four sides of the cylinder body are fixedly connected with heat sinks, and the heat sinks are distributed at equal distances on the outer wall of the cylinder body.

[0018] As another improvement supplement of the present application, the cooling effect on the cylinder body can be further improved by using a heat sink, so that the cylinder body will not overheat and shut down during the continuous air compression process.

[0020] As another improvement supplement to the present application, during the process of air suction in the intake pipe, negative pressure suction will be generated at the end, thereby driving the blades to rotate, and during the rotation of the blades, the rotating column can be driven to rotate, and the rotation of the rotating column can drive the gear ring frame to rotate together, and during the rotation of the gear ring frame, the first gear meshing with it can be driven to rotate, and the rotation of the first gear can drive the first rotating rod to rotate, and when the first rotating rod rotates, the second rotating rod and the second gear can be driven to rotate, and at the same time, the second gear and the third gear are meshed, and the circumferential inner wall of the third gear is fixedly connected to the third rotating rod, so the third rotating rod will rotate, thereby providing a power source for the subsequent dust removal component, and the entire power comes from the intake airflow of the air compressor, which can be achieved without the use of other electrical energy or mechanical energy, thereby reducing the production cost of the air compressor.

[0021] As another improvement of the present application, the dust removal assembly includes a sleeve fixedly connected to the circumferential outer wall of the third rotating rod, the circumferential outer wall of the sleeve is fixedly connected to a push rod, one side outer wall of the vertical plate is rotatably connected to a rotating shaft, the circumferential outer wall of the rotating shaft is fixedly connected to a rotating disk, the circumferential outer wall of the rotating disk is fixedly connected to a cleaning plate, one side outer wall of the cleaning plate contacts one side outer wall of the second filter screen, one side outer wall of the rotating disk is fixedly connected to a cross bar, one end of the push rod away from the sleeve is rotatably connected to an extension rod, one side outer wall of the extension rod is fixedly connected to a spring, one end of the spring away from the extension rod is fixedly connected to one side outer wall of the push rod, and one side outer wall of the extension rod is pressed against one side outer wall of the cross bar.

[0022] As another improvement supplement to the present application, the sleeve can be driven to rotate during the rotation of the third rotating rod. When the sleeve makes a circular motion, the push rod and the cross bar at one end of it can be driven to rotate together. When the cross bar rotates, it will contact the extension rod and push the cleaning plate. When the cleaning plate rotates, the second filter screen on one side of the suction plate can be effectively scraped off. At the same time, when the cleaning plate is lifted to a certain height, the spring on one side of the extension rod will bend and deform. At this time, the extension rod is separated from the cross bar. The cleaning plate lifted to a certain height will rotate in the opposite direction due to gravity and reset. It can also reversely clean and scrape the second filter screen. At the same time, during the continuous operation of the air compressor, the suction component, power component and dust removal component can all work continuously, thereby ensuring the stability of the air compressor during operation.

[0023] In summary, after adopting the above structure, the present invention has the following advantages compared with the prior art:

[0024] 1. The use of the above-mentioned air intake component can speed up the flow rate of the air around the cylinder body, and at the same time, the cooling effect on the cylinder body can be further improved in combination with the heat sink, so that the cylinder body will not overheat and shut down during the continuous air compression process. When the air compressor is started, negative pressure suction will be generated at the intake pipe. At this time, negative pressure suction will also be generated in the cooling pipe connected to the intake pipe, and an air intake plate is connected to one end of the cooling pipe. The air intake groove opened on one side of the air intake plate can speed up the flow rate of the air around the cylinder body. At the same time, the air intake groove is inclined elliptical, which expands the air intake area of ​​the air intake plate, avoids dead corners when the cylinder body is cooled, and meets people's air intake and heat dissipation needs. When the air intake plate speeds up the flow rate of the gas around the cylinder body, the negative pressure suction near the intake hole is greater. Therefore, the air intake plate is set to be thick at both ends and narrow in the middle. The air flow rate on both sides of the intake plate can be increased, so that the air flow rate in each area can be relatively balanced, thereby achieving uniform cooling around the cylinder body.

[0025] 2. When the above-mentioned power assembly is used, negative pressure suction will be generated at the end during the process of air suction in the intake pipe, thereby driving the blades to rotate. During the rotation of the blades, the rotating column can be driven to rotate, and the rotation of the rotating column can drive the gear ring frame to rotate together. During the rotation of the gear ring frame, the first gear meshed with it can be driven to rotate, and the rotation of the first gear can drive the first rotating rod to rotate. When the first rotating rod rotates, the second rotating rod and the second gear can be driven to rotate. At the same time, the second gear and the third gear are meshed, and the circumferential inner wall of the third gear is fixedly connected to the third rotating rod. Therefore, the third rotating rod will rotate, thereby providing a power source for the subsequent dust removal assembly, and the entire power comes from the intake airflow of the air compressor, which can be achieved without the use of other electrical energy or mechanical energy, thereby reducing the production cost of the air compressor.

[0026] 3. By adopting the above-mentioned dust removal component, during the process of air intake and heat dissipation, the second filter screen can be dusted, and the blockage of the second filter screen can be avoided to affect the heat dissipation effect of the entire intake assembly on the cylinder body. Specifically, during the rotation of the third rotating rod, the sleeve can be driven to rotate. When the sleeve makes a circular motion, the push rod and the cross bar at one end thereof can be driven to rotate together. When the cross bar rotates, it will contact the extension rod to push the cleaning plate. When the cleaning plate rotates, the second filter screen on one side of the intake plate can be effectively scraped off. At the same time, when the cleaning plate is lifted to a certain height, the spring on one side of the extension rod will bend and deform. At this time, the extension rod is separated from the cross bar, and the cleaning plate lifted to a certain height will rotate in the opposite direction due to gravity to reset, and the second filter screen can also be cleaned and scraped off in the opposite direction. At the same time, during the continuous operation of the air compressor, the intake assembly, the power assembly and the dust removal assembly can all work continuously, thereby ensuring the stability of the air compressor during operation.

At this time, negative pressure suction will also be generated in the cooling pipe 23 connected to the air intake pipe 7, and one end of the cooling pipe 23 is connected to an air intake plate 2401. The air intake groove 2403 opened on one side of the air intake plate 2401 can accelerate the flow rate of air around the cylinder body 5.

When the air intake plate 2401 accelerates the gas flow rate around the cylinder body 5, since the negative pressure suction near the air intake hole 2406 is greater, the air intake plate 2401 is set to be thick at both ends and narrow in the middle. The air flow on both sides of the air intake plate 2401 can be increased, so that the air flow rate in each area can be relatively balanced, thereby achieving uniform cooling around the cylinder body 5.

[0049] In the present invention, the power assembly includes a support rod 13 fixedly connected to the circumferential outer wall of the intake pipe 7, the support rod 13 is fixedly connected to a bearing seat 14 away from the intake pipe 7, a positioning plate 15 is fixedly connected to one side of the support rod 13, a rotating column 11 is fixedly connected to the circumferential inner wall of the bearing seat 14, a shaft sleeve 9 is arranged at one end of the rotating column 11 away from the bearing seat 14, blades 10 distributed in a circular shape with equal distances are fixedly connected to the circumferential outer wall of the shaft sleeve 9, the rotating column 11 is rotatably connected to the positioning plate 15, the circumferential outer wall of the rotating column 11 is fixedly connected to a gear ring frame 12, and the gear ring The frame 12 is meshed with a first gear 16, and a first rotating rod 17 is fixedly connected to an outer wall of one side of the first gear 16. A vertical plate 36 is fixedly connected to the circumferential outer wall of the air intake pipe 7, and the bottom of the vertical plate 36 is fixedly connected to the top outer wall of the air intake plate 2401. One end of the first rotating rod 17 is fixedly connected to a second rotating rod 26, and a second gear 27 is fixedly connected to the circumferential outer wall of the second rotating rod 26. The second rotating rod 26 is rotatably connected to the vertical plate 36. The second gear 27 is meshed with a third gear, and a third rotating rod 28 is fixedly connected to the circumferential inner wall of the third gear. Figure 3 As shown, during the process of air intake in the intake pipe 7, negative pressure suction will be generated at the end, thereby driving the blade 10 to rotate. During the rotation of the blade 10, the rotating column 11 can be driven to rotate, and the rotation of the rotating column 11 can drive the gear ring frame 12 to rotate together. During the rotation of the gear ring frame 12, the first gear 16 meshing therewith can be driven to rotate, and the rotation of the first gear 16 can drive the first rotating rod 17 to rotate. When the first rotating rod 17 rotates, the second rotating rod 26 and the second gear 27 can be driven to rotate. At the same time, the second gear 27 is meshed with the third gear, and the circumferential inner wall of the third gear is fixedly connected to the third rotating rod 28. Therefore, the third rotating rod 28 will rotate, thereby providing a power source for the subsequent dust removal component, and the entire power comes from the intake airflow of the air compressor, which can be achieved without the use of other electrical energy or mechanical energy, thereby reducing the production cost of the air compressor.

[0050] In the present invention, the dust removal assembly includes a sleeve 29 fixedly connected to the circumferential outer wall of the third rotating rod 28, the circumferential outer wall of the sleeve 29 is fixedly connected to a push rod 30, one side outer wall of the vertical plate 36 is rotatably connected to a rotating shaft 35, the circumferential outer wall of the rotating shaft 35 is fixedly connected to a rotating disk 31, the circumferential outer wall of the rotating disk 31 is fixedly connected to a cleaning plate 25, one side outer wall of the cleaning plate 25 contacts one side outer wall of the second filter screen 2402, one side outer wall of the rotating disk 31 is fixedly connected to a cross bar 34, one end of the push rod 30 away from the sleeve 29 is rotatably connected to an extension rod 33, one side outer wall of the extension rod 33 is fixedly connected to a spring 32, one end of the spring 32 away from the extension rod 33 is fixedly connected to one side outer wall of the push rod 30, and one side outer wall of the extension rod 33 is pressed against one side outer wall of the cross bar 34, as shown in FIG.

When the sleeve 29 makes a circular motion, it can drive the push rod 30 and the cross bar 34 at one end thereof to rotate together. When the cross bar 34 rotates, it will contact the extension rod 33 to push the cleaning plate 25. When the cleaning plate 25 rotates, the second filter 2402 on one side of the intake plate 2401 can be effectively scraped off. At the same time, when the cleaning plate 25 is lifted to a certain height, the spring 32 on one side of the extension rod 33 will bend and deform. At this time, the extension rod 33 is separated from the cross bar 34. The cleaning plate 25 lifted to a certain height will rotate in the opposite direction due to gravity and reset. It can also reversely clean and scrape the second filter 2402. At the same time, during the continuous operation of the air compressor, the intake component 24, the power component and the dust removal component can all work continuously, thereby ensuring the stability of the air compressor during operation.

[0051] In summary, the working principle of the first embodiment is that when the air compressor is started, negative pressure suction will be generated at the air intake pipe 7. At this time, negative pressure suction will also be generated in the cooling pipe 23 connected to the air intake pipe 7, and one end of the cooling pipe 23 is connected to the air intake plate 2401. The air intake groove 2403 opened on one side of the air intake plate 2401 can accelerate the flow rate of air around the cylinder 5. At the same time, the air intake groove 2403 is inclined elliptical, which expands the air intake area of ​​the air intake plate 2401, avoids dead corners when cooling the cylinder 5, and meets people's air intake and heat dissipation needs. When the air intake plate 2401 accelerates the flow rate of gas around the cylinder 5, due to the proximity to the air intake hole 24 The negative pressure suction force at 06 is greater, so the air intake plate 2401 is set to be thick at both ends and narrow in the middle, which can increase the air flow on both sides of the air intake plate 2401, so that the air flow rate in each area can be relatively balanced, and the uniform cooling of the area around the cylinder body 5 is achieved. During the air intake process of the intake pipe 7, negative pressure suction force will be generated at the end, thereby driving the blade 10 to rotate, and the rotation column 11 can be driven to rotate during the rotation of the blade 10. The rotation of the rotating column 11 can drive the gear ring frame 12 to rotate together, and during the rotation of the gear ring frame 12, the first gear 16 meshing therewith can be driven to rotate, and the rotation of the first gear 16 can drive the first rotating The rod 17 rotates, and when the first rotating rod 17 rotates, the second rotating rod 26 and the second gear 27 can be driven to rotate. At the same time, the second gear 27 and the third gear are meshed, and the circumferential inner wall of the third gear is fixedly connected with the third rotating rod 28. Therefore, the third rotating rod 28 will rotate, thereby providing a power source for the subsequent dust removal component, and the entire power comes from the intake airflow of the air compressor, which can be achieved without the use of other electrical energy or mechanical energy, thereby reducing the production cost of the air compressor. In the process of intake heat dissipation, the third rotating rod 28 can drive the sleeve 29 to rotate, and when the sleeve 29 makes a circular motion, it can drive the push rod 30 and the cross bar 34 at one end thereof to rotate together. When the cross bar 34 rotates, it will contact the extension rod 33 and push the cleaning plate 25. When the cleaning plate 25 rotates, the second filter 2402 on the side of the suction plate 2401 can be effectively scraped. At the same time, when the cleaning plate 25 is lifted to a certain height, the spring 32 on the side of the extension rod 33 will bend and deform. At this time, the extension rod 33 is separated from the cross bar 34. The cleaning plate 25 lifted to a certain height will rotate in the opposite direction due to gravity and reset. It can also reversely clean and scrape the second filter 2402. At the same time, during the continuous operation of the air compressor, the suction component 24, the power component and the dust removal component can all work continuously, thereby ensuring the stability of the air compressor during operation.

The heat sinks 8 can further improve the cooling effect of the cylinder body 5, so that the cylinder body 5 will not overheat and shut down during the continuous air compression process.

[0054] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
