Description

Technical Field

[0001] This invention relates to the field of air compressor technology, and more particularly to an air compressor oil supply and lubrication device. Background Technology

[0002] An air compressor is a device that draws in air from the atmosphere and compresses it to a higher pressure through mechanical action. It is widely used in many fields such as industrial production, automobile repair, household cleaning, and medical equipment. According to different working principles, air compressors can be mainly divided into reciprocating compressors and centrifugal compressors. Among them, lubrication of air compressors is very important. It helps to reduce wear, improve efficiency and extend the service life of the machine. For reciprocating compressors, there is friction between the cylinder and the piston, so lubrication can prevent overheating and wear.

[0003] Existing patent CN118775216A discloses a piston-type air compressor, including a housing with a crankshaft structure inside. The upper end of the crankshaft structure is connected to a movable plate that can move up and down. A push rod is fixedly connected to the upper end of the movable plate. A storage component is located within the housing. The upper end of the push rod passes through the storage component and is connected to a piston component. A conveying component and a rotating component are located within the piston component, with one end of the rotating component connected to the conveying component. A lubricating component is located on the piston component and connected to the rotating component. A conductive component is connected to the conveying component, with its output end positioned above the lubricating component. A connecting component is located within the housing, and the rotating component is connected to the connecting component. This device provides cooling oil to the piston seat during air compression, thereby reducing the heat of the piston seat, further protecting the components on the piston seat, indirectly increasing the service life of the piston seat, and further improving the practicality of the device.

[0004] The above structure can lubricate the piston, but it cannot cool the piston according to its heat dissipation temperature. This can easily lead to over-lubrication, wasting lubricating oil and contaminating the system. Alternatively, insufficient lubrication can increase friction and accelerate wear, resulting in excessively high local temperatures. The inability to adjust piston lubrication according to its temperature makes it difficult to ensure the equipment operates within a reasonable temperature range, causing inefficient operation, hindering optimal performance, reducing overall efficiency, and shortening the equipment's lifespan.

[0018] The beneficial effects of this invention are as follows:

[0019] This invention fills the oil supply assembly with lubricating oil. When compressing air, air is continuously input into the compression cylinder through the air supply pipe, activating the drive mechanism and forcing the compression assembly to move back and forth. This causes the compression assembly to compress the air in the compression cylinder. When the air is compressed to a reasonable pressure, it is released into the storage cylinder for storage. Compressed air is then supplied to other equipment through the air supply pipe. The friction between the compression assembly and the inner wall of the compression cylinder generates heat, causing the compression assembly temperature to rise. When the temperature rises above a set value, a detection component detects this and transmits the temperature to the expansion component. The expansion component expands, forcing the oil supply assembly to deliver lubricating oil to the oil storage assembly. When the compression assembly moves to the position of the oil injection assembly, compressed air is introduced into the oil storage assembly, forcing the compressed air to drive the push assembly. This push assembly then pushes the lubricating oil in the oil storage assembly into the oil injection assembly. Under the high pressure of the compressed gas, the oil injection assembly is forced to spray lubricating oil onto the compression assembly, cooling it down. After the compression assembly cools down, the detection component detects this and transmits the temperature to the expansion assembly. At this point, the expansion assembly contracts, forcing the oil supply assembly to retract, thus... The lubricating oil in the oil supply assembly continuously enters the oil delivery assembly to a suitable position, preparing to provide lubricating oil for the oil storage assembly. Simultaneously, the oil storage assembly is disconnected from the storage cylinder, causing the pushing assembly to retract to its original position. This process is repeated. At high temperatures, lubricating oil is continuously sprayed out; at low temperatures, lubricating oil is continuously replenished. In summary, this air compressor oil supply and lubrication device can regulate the temperature of the compression assembly based on the temperature generated by the frictional heat between the compression assembly and the compression cylinder. At high temperatures, the temperature is used to deliver lubricating oil to the oil storage assembly, utilizing the compression... The high pressure of the air pushes the lubricating oil to the oil injection component for spraying. The higher the temperature, the more lubricating oil is delivered and sprayed, achieving rapid cooling and efficient use of lubricating oil. At low temperatures, the temperature can be used to replenish the lubricating oil in the oil supply component, facilitating the delivery of lubricating oil to the oil storage component at high temperatures. This allows for the regulation of the lubricating oil supply based on the temperature of the compression component, ensuring that the equipment operates within a reasonable range, promoting efficient operation, ensuring optimal performance, improving overall equipment efficiency, and extending the equipment's service life.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0033] Example 1:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an air compressor oil supply and lubrication device of the present invention includes a support frame 1, a compression cylinder 2 and a storage cylinder 3 connected to the compression cylinder 2 are provided on the support frame 1, a connecting pipe is provided between the compression cylinder 2 and the storage cylinder 3, a valve is provided on the connecting pipe for control, an air supply pipe 4 for conveying air is provided on the compression cylinder 2, and an air supply pipe 5 for supplying compressed air is provided on the storage cylinder 3.

[0035] A drive mechanism 6 is provided on the support frame 1, and a compression component 7 adapted to the compression cylinder 2 is provided on the drive mechanism 6. The compression component 7 rubs against the compression cylinder 2.

[0036] The compression cylinder 2 is equipped with an oil supply component 8, the compression component 7 is equipped with a temperature detection component 9, the detection component 9 is equipped with an expansion component 10, the compression cylinder 2 is equipped with an oil delivery component 11 connected to the oil supply component 8, the expansion component 10 is located inside the oil delivery component 11, the compression cylinder 2 is equipped with an oil storage component 12 connected to the oil delivery component 11 and the storage cylinder 3, the oil storage component 12 is equipped with a push component 13, the compression cylinder 2 is equipped with an oil injection component 14 connected to the oil storage component 12, and the oil injection component 14 sprays oil onto the compression component 7.

[0037] Working principle: The oil supply assembly 8 is filled with lubricating oil. When compressing air, air is continuously input into the compression cylinder 2 through the air supply pipe 4. The drive mechanism 6 is activated, forcing the compression assembly 7 to move back and forth, thus compressing the air in the compression cylinder 2. When the air is compressed to a reasonable pressure, it is released into the storage cylinder 3 for storage. Compressed air is then supplied to other equipment through the air supply pipe 5. Heat is generated due to the back-and-forth friction between the compression assembly 7 and the inner wall of the compression cylinder 2, causing the temperature of the compression assembly 7 to rise. When the temperature rises above a set value, the detection component 9 detects this and transmits the temperature to the expansion assembly 10. The expansion assembly 10 expands, forcing the oil delivery assembly 11 to deliver lubricating oil to the oil reservoir 12. When the compression assembly 7 moves to the position of the injection assembly 14, it introduces compressed air into the oil reservoir 12, forcing the compressed air to drive the push assembly 13 to move. The push assembly 13 then pushes the lubricating oil in the oil reservoir 12 into the injection assembly 14. Under the high pressure of the compressed gas, the injection assembly 14 is forced to spray lubricating oil onto the compression assembly 7, cooling the compression assembly 7. After the compression assembly 7 cools down, the detection assembly 9 is forced to detect the temperature and transfer it to the expansion assembly 10. At this time, the expansion assembly 10 contracts, forcing... The oil delivery assembly 11 is retracted, allowing lubricating oil from the oil supply assembly 8 to continuously enter the oil delivery assembly 11 to a suitable position, preparing to provide lubricating oil for the oil storage assembly 12. Simultaneously, the oil storage assembly 12 is disconnected from the storage cylinder 3, causing the push assembly 13 to retract to its original position. This process is repeated, continuously spraying lubricating oil when the temperature is high and replenishing it when the temperature is low. In summary, this air compressor oil supply and lubrication device can regulate the temperature of the compression assembly 7 based on the temperature generated by the frictional heat between the compression assembly 7 and the compression cylinder 2. At high temperatures, the temperature is used to deliver lubricating oil to the oil storage assembly. Component 12 uses high-pressure compressed air to push lubricating oil to the oil injection component 14 for spraying. The higher the temperature, the more lubricating oil is delivered and sprayed, achieving rapid cooling and efficient use of lubricating oil. At low temperatures, it can replenish the lubricating oil in the oil supply component 8 to the oil delivery component 11, facilitating the delivery of lubricating oil to the oil storage component 12 at high temperatures. This allows for the adjustment of the lubricating oil supply based on the temperature of the compression component 7, ensuring the equipment operates within a reasonable range, promoting efficient operation, ensuring optimal performance, improving overall equipment efficiency, and extending the equipment's service life.

[0042] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an air compressor oil supply and lubrication device of the present invention includes an oil supply assembly 11 comprising an oil supply cylinder 1101 disposed on a compression cylinder 2, a partition 1102 disposed inside the oil supply cylinder 1101, an oil supply rod 1103 slidably disposed on the partition 1102, an oil supply piston 1104 disposed at one end of the oil supply rod 1103, a force-receiving piston 1105 disposed at the other end of the oil supply rod 1103, an oil supply pipe 804 located between the oil supply cylinder 1101 and the oil supply piston 1104 and communicating with the oil supply cylinder 1101, an oil supply pipe 1106 disposed on the oil supply cylinder 1101, and a one-way valve 1107 installed on the oil supply pipe 1106.

[0043] like Figure 5 , Figure 8 and Figure 9As shown, an air compressor oil supply and lubrication device of the present invention includes a detection component 9 comprising a metal hose 901 disposed on a piston base 702. The metal hose 901 is hollow inside and filled with working fluid. A plurality of liquid suction cores 902 are disposed on the inner wall of the metal hose 901. A heat-conducting rod 903 is disposed at the end of the metal hose 901. The heat-conducting rod 903 is inserted into the piston base 702 and close to the compression piston 703.

[0044] like Figure 8 As shown, an air compressor oil supply and lubrication device of the present invention includes an expansion assembly 10 comprising a heat exchange shell 1001 disposed at the end of a metal hose 901, a heat transfer rod 1002 disposed on the heat exchange shell 1001, an expansion air bladder 1003 disposed on the heat transfer rod 1002, and the expansion air bladder 1003 being located between an oil supply cylinder 1101 and a force-receiving piston 1105.

[0045] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, an air compressor oil supply and lubrication device of the present invention includes an oil storage assembly 12 comprising an oil storage cylinder 1201 disposed on a compression cylinder 2, an air guide pipe 1202 connected to a storage cylinder 3 disposed at one end of the oil storage cylinder 1201, a solenoid valve 1203 disposed on the air guide pipe 1202, a pressure relief valve 1204 disposed on the oil storage cylinder 1201, an oil guide pipe 1205 disposed at the other end of the oil storage cylinder 1201, a one-way valve 1206 installed on the oil guide pipe 1205, the oil storage cylinder 1201 connected to an oil delivery pipe 1106, and the oil guide pipe 1205 connected to an oil injection assembly 14.

[0046] like Figure 7 As shown, an air compressor oil supply and lubrication device of the present invention includes a push assembly 13 comprising a partition 1301 disposed inside an oil storage cylinder 1201, a push rod 1302 disposed on the partition 1301, a pneumatic piston 1303 disposed at one end of the push rod 1302, a spring 1304 sleeved on the outer ring of the push rod 1302 disposed between the pneumatic piston 1303 and the partition 1301, and an oil pusher piston 1305 disposed at the other end of the push rod 1302, wherein the oil pusher piston 1305 is filled with lubricating oil between the oil storage cylinder 1201 and the pneumatic piston 1303 is filled with gas between the pneumatic piston 1303 and the oil storage cylinder 1201.

[0047] like Figure 2 , Figure 5 and Figure 10As shown, an air compressor oil supply and lubrication device of the present invention includes an oil injection assembly 14 comprising an annular pipe 1401 disposed on the inner wall of a compression cylinder 2, the annular pipe 1401 being connected to an oil guide pipe 1205, and the inner wall of the annular pipe 1401 being connected to a plurality of evenly distributed oil distribution pipes 1402, on which oil injectors 1403 are installed. When the compression piston 703 moves to the oil injector 1403, the output end of the oil injector 1403 is aligned with the compression piston 703.

[0048] Working principle: The oil supply tank 802 is filled with lubricating oil through the supply pipe 803 connected to the lubricating oil supply device. When compressing air, air is continuously input into the compressor cylinder 2 through the air supply pipe 4. The motor 602 is started, and the output shaft of the motor 602 rotates, which drives the cam 603 to rotate. The rotation of the cam 603 drives the shaft 604 to rotate, and the shaft 604 drives the connecting rod 605 to move back and forth continuously. This forces the connecting rod 605 to drive the compression rod 701 to move back and forth linearly. The compression rod 701 drives the piston base 702 to move back and forth, which in turn drives the compression piston 703 to move back and forth. This causes the compression piston 703 to continuously compress the input air until the air is compressed to a reasonable pressure, forming compressed air. This forces the compressor cylinder 2 to connect with the storage cylinder 3, so that the compressed air is stored in the storage cylinder 3. The compressed air is then supplied to other equipment through the air supply pipe 5.

[0049] Heat is generated by the back-and-forth friction between the inner wall of the compression cylinder 2 and the compression piston 703, causing the temperature of the compression piston 703 to rise. This, in turn, forces the temperature of the piston base 702 to rise. When the temperature rises above a set value, the heat-conducting rod 903 transfers heat to the metal hose 901, creating a vacuum within the hose. This lowers the boiling point of the working fluid, causing the working fluid, such as water, to absorb heat and evaporate. The water vapor carries the heat to the other end of the hose, where it accumulates. Under the heat transfer action of the heat exchange shell 1001 and the heat transfer rod 1002, the heat is transferred to the expansion bladder 1003, causing it to expand and thus reducing the pressure in the oil delivery cylinder 1101. The increased pressure in the space caused by the gas acts on the piston 1105, forcing it to move. Under the action of the partition 1102, the piston 1103 moves, which in turn moves the oil delivery rod 1103. The oil delivery rod 1103 then moves the oil delivery piston 1104, forcing it to squeeze the lubricating oil in the oil delivery cylinder 1101. Under the action of the oil delivery pipe 1106 and the one-way valve 1107, the lubricating oil is continuously fed into the oil storage cylinder 1201. After the heat exchange is complete, the water vapor releases heat and condenses into liquid. Under the capillary action of the liquid suction core 902, the liquid quickly returns to the end of the metal hose 901, forcing the water to continuously transfer heat until the lubricating oil in the oil storage cylinder 1201 reaches a certain value.

[0050] Oil is injected into the compression piston 703. When the compression piston 703 moves to the oil injector 1403, the solenoid valve 1203 is opened. Since the compressed air stored in the storage cylinder 3 has a high pressure, it forces the compressed air to enter the oil storage cylinder 1201 through the air guide pipe 1202. The compressed air acts on the pneumatic piston 1303, causing the pneumatic piston 1303 to move rapidly, which drives the push rod 1302 to move rapidly, compressing the spring 1304, which causes the push rod 1302 to drive the push piston 1305 to move. At this time, the one-way valve 1206 is opened. Under the action of the oil guide pipe 1205, the push piston 1305 quickly pushes the lubricating oil into the annular pipe 1401. The lubricating oil is introduced into the oil injector 1403 through the oil distribution pipe 1402, and the lubricating oil is sprayed onto the compression piston 703 through the oil injector 1403 to lubricate and cool the compression piston 703.

[0051] When the solenoid valve 1203 is closed and the pressure relief valve 1204 is opened, the compressed air in the oil reservoir 1201 is discharged. Under the action of the spring 1304, the starting piston and the pushing piston are retracted to their original positions. Since the amount of lubricating oil in the oil delivery cylinder is insufficient, the lubricating oil will not enter the oil reservoir 1201 during the retraction of the pushing piston.

[0052] When the compression piston 703 cools down, the temperature of the piston base 702 drops, and the heat transfer between the metal hose 901 and the heat-conducting rod 903 is no longer formed. This causes the temperature of the heat exchange shell 1001 to drop, and the temperature of the heat transfer rod 1002 to drop. At this time, the expansion bladder 1003 contracts, forcing the force-bearing piston 1105 to retract. Under the action of the partition 1102, the oil delivery rod 1103 is driven to retract, and the oil delivery rod 1103 drives the oil delivery piston 1104 to retract. This forces the volume of the oil delivery cylinder 1101 and the oil delivery piston 1104 to increase and the pressure to decrease. Under the action of the oil supply pipe 804 and the one-way valve 805, the lubricating oil in the oil supply tank 802 is continuously delivered to the oil delivery cylinder to prepare for the supply of lubricating oil to the oil storage cylinder 1201. The above steps are repeated. When the temperature is high, the lubricating oil is continuously sprayed out, and when the temperature is low, the lubricating oil is continuously replenished.

[0053] The drive mechanism 6 provides power, converting rotational force into linear reciprocating motion, causing the compression assembly 7 to reciprocate, thereby compressing air and continuously forming compressed air. The compression assembly 7 compresses air, storing it as compressed air. Simultaneously, the piston base 702 and the compression piston 703 provide a seal, and the friction between the compression piston 703 and the compression cylinder 2 generates heat, which affects the detection assembly 9. The oil supply assembly 8 continuously provides lubricating oil, ensuring the device can continuously use lubricating oil. The replenishment pipe 803 continuously replenishes the lubricating oil, preventing oil shortages that could lead to insufficient lubrication and cooling, thus improving the device's efficiency. The one-way valve 8... The 05 setting prevents oil from flowing back into the oil supply tank 802 from the oil delivery cylinder; the oil delivery component 11 enables the delivery of lubricating oil to the oil storage tank 1201, facilitating the transition of lubricating oil and storing it. At low temperatures, it guides lubricating oil from the oil supply tank 802 into the oil delivery cylinder, facilitating replenishment and improving the device's efficiency and ingenuity; the detection component 9 detects the temperature of the piston base 702 and the compression piston 703, utilizing the temperature difference and transferring the temperature to the expansion component 10; the liquid suction core 902 allows the condensed working liquid to flow back to the heat-conducting rod 903 via capillary action, ensuring a continuous supply of heat. The expansion assembly 10 accelerates the return flow of the working fluid, improves heat exchange efficiency, and facilitates temperature transfer. The expansion assembly 10 utilizes temperature to control the expansion bladder 1003. When the temperature rises, the expansion bladder 1003 expands, occupying space, reducing volume, and increasing pressure to achieve mechanical movement. When the temperature is low, the expansion bladder 1003 contracts, causing the force-bearing piston 1105 to retract, thereby controlling the lubricating oil in the oil delivery cylinder and improving the device's efficiency. The oil storage assembly 12 introduces compressed air into the oil storage cylinder 1201, and through the action of the pushing assembly 13, guides lubricating oil into the oil guide pipe 1205, fully utilizing the high pressure of the compressed air, improving the device's efficiency, and storing the lubricating oil for later use. When the compression piston 703 is sprayed with oil in a timely manner, the flexibility of the device is improved. The setting of the push assembly 13 makes full use of the high pressure of compressed air to drive the pneumatic piston 1303 to move, thereby forcing the push piston 1305 to push the lubricating oil to the oil guide pipe 1205. The setting of the spring 1304 can realize the return of the pneumatic piston 1303 and the push piston 1305 to their original positions after movement, so as to prepare for the next movement and improve the rationality of the device. The setting of the oil spray assembly 14 can spray the lubricating oil onto the compression piston 703, so as to achieve the cooling and lubrication of the compression piston 703 and the piston base 702, avoid overheating, reduce the friction between the compression piston 703 and the inner wall of the compression cylinder 2, improve the overall efficiency of the equipment, and extend the service life of the equipment.

[0054] This solution can regulate the temperature of the compression piston 703 and piston base 702 based on the heat generated by the friction between the compression piston 703 and the compression cylinder 2. At high temperatures, the lubricating oil is delivered to the oil reservoir 1201 using the temperature difference, and the lubricating oil is pumped to the oil injector 1403 by the high pressure of compressed air. The higher the temperature, the more lubricating oil is delivered, forcing more lubricating oil to be sprayed out, thus achieving rapid cooling and rational use of lubricating oil. At low temperatures, the lubricating oil in the oil supply tank 802 can be replenished to the oil delivery cylinder using the temperature difference, facilitating the delivery of lubricating oil to the oil reservoir 1201 at high temperatures. This allows for the regulation of the lubricating oil supply based on the temperature of the compression piston 703 and piston base 702, ensuring that the equipment operates within a reasonable temperature range, promoting efficient operation, ensuring optimal performance, improving overall equipment efficiency, and extending the service life of the equipment.
