[0040] The present application provides an air supply system, and the air supply system includes an air supply device. In the present application, by providing a gas collection chamber at the outlet of the compression mechanism, the gas can be buffered in the gas collection chamber to reduce the pressure fluctuation of the gas, thereby improving the stability of the gas.

[0044] Refer to Figure 2 and Figure 3 , Figure 2 which is a schematic structural diagram of an air supply device provided by an embodiment of the present application, Figure 3 which is an internal structural schematic diagram of an air supply device provided by an embodiment of the present application. An embodiment of the present application provides an air supply device 20, including: a driving mechanism 28, a compression mechanism 21, and a gas collection member 22.
[0045] Specifically, refer to Figure 4 andFigure 5 , Figure 4 is Figure 2 a schematic cross-sectional view in the A-A direction in Figure 5 is Figure 2 a schematic structural view of the air collecting member in . The compression mechanism 21 forms a compression chamber 211 having a first opening 212 and a second opening 213. The first opening 212 is for air intake, and the second opening 213 is for air exhaust. In this way, air can enter the compression chamber 211 through the first opening 212, and after being compressed in the compression chamber 211, the air is discharged from the compression chamber 211 through the second opening 213.
[0046] The air collecting member 22 is connected to the compression mechanism 21. The air collecting member 22 forms an air collecting chamber 221 having a third opening 222 and a fourth opening 223. The second opening 213 is in communication with the third opening 222. The cross-sectional area of the air collecting member 22 is larger than the opening area of the second opening 213, and the cross-section is perpendicular to the length extension direction of the air collecting member 22.
[0047] In this way, by providing that the air collecting member 22 is connected to the compression mechanism 21 and the cross-sectional area of the air collecting member 22 is larger than the opening area of the second opening 213, the compression chamber 211 is in communication with the air collecting chamber 221, so that the compressed air in the compression chamber 211 can be buffered in the air collecting chamber 221, the pressure fluctuation of the air can be reduced, the noise of the air supply device 20 can be reduced, and the stability of the air supply device 20 can be improved.
[0048] In addition, since the cross-sectional area of the air collecting member 22 is larger than the opening area of the second opening 213, more air can be accommodated in the air collecting chamber 221, the gas storage capacity in the air supply device 20 is increased, which is beneficial to providing a more stable gas supply and ensuring the stable operation of the system.
[0049] Continuing to refer to Figure 3 , the driving mechanism 28 includes a motor 282. The motor 282 has a motor shaft 283. The motor shaft 283 is mechanically connected to an eccentric shaft 284. The bearing of the eccentric shaft 284 is connected to a connecting rod 285. One end of a pin shaft 286 is connected to the connecting rod 285, and the other end is connected to a piston 23. When the motor 282 rotates, it drives the motor shaft 283 to rotate. The motor shaft 283 drives the eccentric shaft 284 to rotate. The rotation of the eccentric shaft 284 drives the connecting rod 285 to move up and down. The up and down movement of the connecting rod 285 drives the pin shaft 286 to move up and down, thereby driving the piston 23 to make a reciprocating motion in the compression chamber 211.
[0050] In some embodiments, continuing to refer to Figure 4 and combining with Figure 6 , Figure 6 is Figure 3Schematic structural diagram of the middle piston. The air supply device 20 further includes a piston 23. The piston 23 is disposed in the compression chamber 211. It can be understood that the gas is compressed by the reciprocating motion of the piston 23 in the compression chamber 211.
[0051] The piston 23 includes a receiving space 231. The connecting rod 285 is located in the receiving space 231 and is connected to the pin shaft 286. The piston 23 further includes a first end 232 and a second end 233. The piston 23 is configured to reciprocate in the compression chamber 211 along a set direction, and the set direction is the arrangement direction of the first end 232 and the second end 233 of the piston. As Figure 4 shown by the arrow B in
[0052] In some embodiments, the first end 232 of the piston is configured to form a first sub-chamber 234 with one end of the compression mechanism 21 during the movement of the piston 23. The first end 232 of the piston is provided with a first ventilation hole 236, and a first one-way valve 238 is provided in the first ventilation hole 236 of the first end 232 of the piston. The first one-way valve 238 is configured to allow gas to enter the first sub-chamber 234 from the compression chamber 211. The first sub-chamber 234 communicates with the first opening 212 through the first ventilation hole 236. The first sub-chamber 234 also communicates with the second opening 213.
[0053] The second end 233 of the piston is configured to form a second sub-chamber 235 with the other end of the compression mechanism 21 during the movement of the piston 23. The second end 233 of the piston is provided with a second ventilation hole 237, and a second one-way valve 239 is provided in the second ventilation hole 237 of the second end 233 of the piston. The second one-way valve 239 is configured to allow gas to enter the second sub-chamber 235 from the compression chamber 211. The second sub-chamber 235 communicates with the first opening 212 through the second ventilation hole 237. The second sub-chamber 235 also communicates with the second opening 213.
[0054] In this way, by providing the first one-way valve 238 and the second one-way valve 239, the first one-way valve 238 and the second one-way valve 239 only allow gas to enter the first sub-chamber 234 and the second sub-chamber 235 from the compression chamber 211, and the gas will not flow in the reverse direction, improving the sealing performance of the first sub-chamber 234 and the second sub-chamber 235. In addition, this makes the compression process more efficient, avoiding the gas from flowing back into the compression chamber 211, thereby reducing the compression efficiency.
[0055] It should be noted that the volumes of the first sub-chamber 234 and the second sub-chamber 235 may be equal or unequal. This application does not limit this, and it is specifically defined according to the actual situation.
[0056] Exemplarily, the volumes of the first sub-chamber 234 and the second sub-chamber 235 are equal. In this way, the supply of the compressed gas will be more stable.
[0057] In this way, referring to Figure 7 , Figure 7 which is a schematic diagram of a first sub-chamber formed by one end of the piston and the compression mechanism in the embodiment of the present application. When the piston 23 moves towards the other end of the compression mechanism 21, the second end 233 of the piston compresses the gas in the second sub-chamber 235 and discharges it through the second opening 213. The gas enters the first sub-chamber 234 through the first ventilation hole 236, and the gas movement path is as shown by the arrow in Figure 7 . Referring to Figure 8 , Figure 8 which is a schematic diagram of a second sub-chamber formed by the piston towards the other end of the compression mechanism in the embodiment of the present application. When the piston 23 moves towards one end of the compression mechanism 21, the first end 232 of the piston compresses the gas in the first sub-chamber 234 and discharges it through the second opening 213. The gas enters the second sub-chamber 235 through the second ventilation hole 237, and the gas movement path is as shown by the arrow in Figure 8 . In this way, the air supply device 20 can continuously supply compressed gas, improving the efficiency of the air supply device 20.
[0058] It should be noted that the number of the first ventilation hole 236 and the second ventilation hole 237 can be one or more, and the present application does not make specific limitations on this.
[0059] Exemplarily, the number of the first ventilation hole 236 and the second ventilation hole 237 is four. In this way, it is convenient for air to enter the first sub-chamber 234 and the second sub-chamber 235.
[0060] It should be noted that the number of the first one-way valve 238 and the second one-way valve 239 is set in one-to-one correspondence with the number of the first ventilation hole 236 and the second ventilation hole 237.
[0061] Exemplarily, the number of the first one-way valve 238 and the second one-way valve 239 is four.
[0062] It can be understood that in order to enhance the sealing performance of the first sub-chamber 234 and the second sub-chamber 235, sealing sleeves or sealing rings can be provided on the surfaces of the first end 232 of the piston and the second end 233 of the piston in contact with the compression mechanism 21. The sealing sleeve is generally fixed on the piston 23 through a sealing end cover. The sealing ring can be sleeved on the circumferential side of the first end 232 of the piston or the circumferential side of the second end 233 of the piston.
[0063] It should be noted that the sealing sleeve and the sealing ring can be made of materials such as rubber, polyurethane or metal.
[0064] Exemplarily, the sealing sleeve can be a leather cup, and the sealing ring can be a piston ring.
[0065] In some embodiments, at least one piston ring can be respectively provided on the first end 232 of the piston and the second end 233 of the piston.

The common end where the second end 242 of the first exhaust passage is communicated with the second end 252 of the second exhaust passage is connected to the second opening 213.
[0070] In this way, the communication between the second end 242 of the first exhaust passage and the second end 252 of the second exhaust passage can reduce the exhaust resistance and improve the exhaust efficiency of the compressor. In addition, the common end where the second end 242 of the first exhaust passage is communicated with the second end 252 of the second exhaust passage is connected to the second opening 213, which can simplify the structure of the compression mechanism 21, reduce the production cost, and at the same time facilitate the maintenance and cleaning of the exhaust passage.

A fourth check valve 253 is provided at the first end 251 of the second exhaust passage, and the fourth check valve 253 is configured to allow gas to enter the second exhaust passage 25 from the second sub-chamber 235.
[0072] In this way, by providing a third one-way valve 243 at the first end 241 of the first exhaust passage, the first sub-chamber 234 is isolated from the first exhaust passage 24, allowing only gas to enter the first exhaust passage 24 from the first sub-chamber 234. The gas does not flow in the reverse direction, preventing the first sub-chamber 234 from sucking back the gas in the first exhaust passage 24, improving the sealing performance of the first sub-chamber 234 and enhancing the compression efficiency. By providing a fourth one-way valve 253 at the first end 251 of the second exhaust passage, the second sub-chamber 235 is isolated from the second exhaust passage 25, allowing only gas to enter the second exhaust passage 25 from the second sub-chamber 235. The gas does not flow in the reverse direction, preventing the second sub-chamber 235 from sucking back the gas in the second exhaust passage 25, improving the sealing performance of the second sub-chamber 235 and enhancing the compression efficiency.
[0073] In some embodiments, referring to Figure 4 and combining with Figure 9 , Figure 9 is Figure 2 a schematic structural view of the compression mechanism in
[0074] a compression mechanism 21 is provided with a first exhaust passage 24 and a second exhaust passage 25. The first end 241 of the first exhaust passage communicates with the first sub-chamber 234, and the first end 251 of the second exhaust passage 24 communicates with the second sub-chamber 235. The second opening 213 includes independent first and second sub-openings 215 and 216. The second end 242 of the first exhaust passage communicates with the first sub-opening 215, and the second end 252 of the second exhaust passage 24 communicates with the second sub-opening 216.
[0075] In some embodiments, a third one-way valve 243 is provided at the first end 241 or the second end 242 of the first exhaust passage. The third one-way valve 243 is configured to allow gas to enter the first exhaust passage 24 from the first sub-chamber 234.

[0076] In this way, since the first exhaust passage 24 and the second exhaust passage 25 are respectively connected to independent sub-openings, by providing a third one-way valve 243 at the first end 241 or the second end of the first exhaust passage, the first sub-chamber 234 is isolated from the gas collection chamber 221, allowing only gas to enter the gas collection chamber 221 from the first sub-chamber 234. The gas will not flow in the reverse direction, preventing the first sub-chamber 234 from sucking back the gas in the gas collection chamber 221, improving the sealing performance of the first sub-chamber 234 and enhancing the compression efficiency. By providing a fourth one-way valve 253 at the first end 251 or the second end of the second exhaust passage, the second sub-chamber 235 is isolated from the gas collection chamber 221, allowing only gas to enter the gas collection chamber 221 from the second sub-chamber 235. The gas will not flow in the reverse direction, preventing the second sub-chamber 235 from sucking back the gas in the second exhaust passage 25, improving the sealing performance of the second sub-chamber 235 and enhancing the compression efficiency.
[0077] Exemplarily, a third one-way valve 243 is provided at the first end 241 of the first exhaust passage, and a fourth one-way valve 253 is provided at the first end 251 of the second exhaust passage.
[0078] In some embodiments, referring again to Figure 4 , the air supply device 20 further includes a pressure relief valve 26, and the pressure relief valve 26 is in communication with the gas collection chamber 221. The pressure relief valve 26 is configured to open when the gas pressure in the gas collection chamber 221 is greater than or equal to the pressure relief threshold of the pressure relief valve 26.
[0079] In this way, when the gas pressure in the gas collection chamber 221 exceeds the pressure relief threshold, the pressure relief valve 26 will open to discharge the excess gas, preventing the pressure in the gas collection chamber 221 from being too high and avoiding equipment damage or safety accidents caused by overpressure. By providing the pressure relief valve 26, the pressure in the gas collection chamber 221 can be effectively controlled, ensuring the safe operation of the equipment and enhancing the safety of the entire system.
[0080] In some embodiments, referring again to Figure 4 , the air supply device 20 further includes an electromagnetic valve 27, and the electromagnetic valve 27 is in communication with the gas collection chamber 221. The electromagnetic valve 27 is configured to open when receiving a control signal.
[0081] In this way, the electromagnetic valve 27 can be remotely controlled by a control signal without manual operation, which is convenient and fast. The electromagnetic valve 27 can cooperate with other devices to achieve automatic control and improve work efficiency.
[0082] It can be understood that in case of equipment failure or safety hazards, the control system will issue a control signal to open the electromagnetic valve 27 to release the compressed air for emergency treatment. In some specific scenarios, such as regular maintenance, cleaning, etc., the control system will issue a control signal to open the electromagnetic valve 27 to release the compressed air for the next step of treatment.
[0083] In some embodiments, referring to Figure 10 , Figure 10 which is a schematic cross-sectional view of the intake passage of the drive mechanism in the embodiment of the present application. The air supply device 20 further includes a drive mechanism 28. The drive mechanism 28 is connected to the piston 23 and is configured to drive the piston 23 to move. The drive mechanism 28 is provided with an intake passage 281, and the intake passage 281 communicates with the first opening 212.
[0084] In this way, the gas enters the compression chamber 211 through the intake passage 281 of the drive mechanism 28. When the gas flows through the drive mechanism 28, it can cool down the drive mechanism 28 and effectively dissipate heat from the drive mechanism 28.
[0085] In some other embodiments, referring to Figure 11 , Figure 11 which is a schematic cross-sectional view of the intake passage of the drive mechanism in another embodiment of the present application. The compression chamber 211 is further provided with a fifth opening 214, and the intake passage 281 communicates with the fifth opening 214.
[0086] In this way, the gas can enter the compression chamber 211 through the first opening 212 of the compression chamber 211, or can enter the compression chamber 211 through the intake passage 281 of the drive mechanism 28 and then through the fifth opening 214, ensuring the air supply of the air supply device 20.
[0087] In some embodiments, referring again to Figure 2 , the air supply device 20 further includes a filter 29 and an intake pipe 30. One end of the intake pipe 30 communicates with the filter 29, and the other end communicates with the first opening 212.
[0088] In this way, the filter 29 can effectively remove impurities in the compressed air, such as dust, oil stains, water droplets, etc., ensuring the cleanliness of the air entering the compression assembly, extending the service life of the compression assembly, and improving the reliability of the air supply device 20. In addition, the clean air can reduce the wear of the compression assembly and extend the service life of the air supply device 20.
